                        SPECIAL MEETING OF STOCKHOLDERS


                MERGERS PROPOSED -- YOUR VOTE IS VERY IMPORTANT



     The boards of directors of World Access, Inc. and STAR Telecommunications,
Inc. have agreed on a merger that will combine the businesses of World Access
and STAR. The STAR merger agreement also provides for the sale of PT-1
Communications, Inc., STAR's subsidiary, to a third party.



     As a result of the STAR merger, World Access will issue a total of
approximately 22.9 million shares of World Access common stock assuming World
Access chooses to pay all of the consideration in stock. Each outstanding share
of STAR common stock will be converted into the right to receive, at the
election of World Access:



     - 0.386595 shares of World Access common stock, subject to adjustment as
       described in the accompanying joint proxy statement/prospectus; or



     - a combination of shares of World Access common stock and cash.



     The board of directors of World Access has also agreed on a merger that
will combine the businesses of World Access and Communication TeleSystems
International, which does business as WorldxChange Communications. As a result
of the WorldxChange merger, World Access will issue a total of approximately
29.8 million shares of World Access common stock. Each outstanding share of
WorldxChange common stock, including shares of preferred stock deemed to be
automatically converted into shares of common stock immediately before
completion of the WorldxChange merger, will be converted into the right to
receive 0.6583 shares of World Access common stock.



     The World Access common stock is traded on the Nasdaq National Market under
the symbol "WAXS." The closing price for the World Access common stock on August
1, 2000 was $8 11/16 per share. FOR A DISCUSSION OF RISK FACTORS YOU SHOULD
CONSIDER IN EVALUATING THE MERGERS AND THE PT-1 ASSET SALE, SEE "RISK FACTORS"
BEGINNING ON PAGE 29.



     STAR cannot complete the STAR merger or the PT-1 asset sale without the
approval of its stockholders, and World Access cannot complete the STAR merger
or the WorldxChange merger without the approval of its stockholders. STAR and
World Access have scheduled special meetings to vote on these transactions and
other important proposals. A joint proxy statement/prospectus accompanies this
letter and provides detailed information about the special meetings, the STAR
merger, the WorldxChange merger and the PT-1 asset sale. In addition, you may

                             QUESTIONS AND ANSWERS


                             ABOUT THE STAR MERGER


Q:  WHAT IS THE STAR MERGER?


A:   The boards of directors of World Access and STAR have voted to combine the
     businesses of World Access and STAR. To combine the companies, STAR will
     merge with a subsidiary of World Access, becoming a wholly-owned subsidiary
     of World Access. The completion of the STAR merger is conditioned on the
     sale of PT-1 by STAR. Unless World Access waives this condition, World
     Access will be merging with STAR minus its PT-1 operations if we complete
     the STAR merger. After the STAR merger, the percentage in voting power of
     the combined companies that will be owned by the pre-merger stockholders
     under the two possible consideration alternatives will be as follows:

     100% World Access stock...................................    82%     18%        --

</TABLE>



Q:   WHAT WILL STAR STOCKHOLDERS RECEIVE IN THE STAR MERGER?



A:   World Access has the option to pay STAR stockholders one of two forms of
     consideration when the STAR merger is completed. Assuming a value of $9.00
     per share of World Access common stock, World Access will issue a total
     dollar value of approximately $205.0 million to the STAR stockholders in
     consideration in the STAR merger. STAR stockholders who are entitled to and
     exercise dissenters' rights of appraisal under Delaware law will not
     receive either form of merger consideration.



     If World Access selects the first form of consideration, each STAR
     stockholder will be entitled to receive, for each share of STAR common
     stock, 0.386595 shares of World Access common stock. This amount is subject
     to upward adjustment if STAR sells PT-1 prior to the completion of the STAR
     merger for net cash proceeds in excess of $150.0 million.



     If World Access selects the second form of consideration, each STAR
     stockholder will be entitled to receive, for each share of STAR common
     stock, the same total value as that paid in the first form of
     consideration. However, under the second form, each STAR stockholder will
     receive up to 60% of its consideration in World Access common stock and up
     to 40% of its consideration in cash. If World Access selects the second
     form of consideration, each STAR stockholder will receive the same
     percentages of stock and cash as other STAR stockholders.



     World Access will not issue fractional shares. World Access will issue cash
     instead of fractional shares based on the average closing price of World
     Access common stock as reported on the Nasdaq Stock Market for the ten-day
     trading period ending at the close of trading on the date of the completion
     of the STAR merger.



     The following table shows the approximate number of shares of World Access
     common stock and amount of cash instead of fractional shares that a STAR
     stockholder will receive upon completion of the STAR merger if World Access
     selects the first form of consideration. This table assumes an average
     closing sale price for the World Access common stock of $9.00 for the
     purpose of calculating the amount of cash paid instead of fractional shares
     and the value of total consideration received.

     The following table shows the approximate number of shares of World Access
     common stock and amount of cash, including cash instead of fractional
     shares, that a STAR stockholder will receive if World Access selects the
     second form of consideration and pays 40% of the consideration to each STAR
     stockholder in cash and pays 60% of the consideration in the form of World
     Access common stock. This table assumes an average closing sale price for
     the World Access common stock of $9.00 per share for the purpose of
     calculating the amount of cash paid instead of fractional shares, the total
     amount of all cash received and the value of total consideration received.
     These assumptions are solely for purposes of illustrating the two forms of
     consideration. The calculation of the amount of cash to be received as STAR
     merger consideration will actually be based on the average closing price of
     World Access common stock for the ten-day trading period ending at the
     close of trading on the date immediately before the completion of the STAR
     merger.

     If STAR completes the PT-1 asset sale to Counsel, the net cash proceeds
will be less than $150.0 million.



Q:   WHAT HAPPENS IF STAR DOES NOT SELL PT-1 PRIOR TO THE COMPLETION OF THE STAR
     MERGER?



A:   If STAR does not sell PT-1 prior to the completion of the STAR merger, then
     World Access does not have to complete the STAR merger.



Q:   WHAT HAPPENS IF STAR SELLS PT-1 FOR LESS THAN NET CASH PROCEEDS OF AT LEAST
     $150.0 MILLION?



A:   If STAR sells PT-1 to a buyer other than Counsel and does not receive net
     cash proceeds of at least $150.0 million from that sale, then World Access
     does not have to complete the STAR merger. However, the STAR merger
     agreement provides that the condition to World Access' obligations under
     the STAR merger agreement relating to the sale of PT-1 will be deemed
     satisfied if STAR sells the assets of PT-1 to Counsel under the PT-1 asset
     sale agreement.



Q:   WHAT IS THE WORLDXCHANGE MERGER?



A:   World Access has also agreed to a merger with WorldxChange. The STAR merger
     does not depend on the completion of the WorldxChange merger, and the
     WorldxChange merger does not depend on the completion of the STAR merger.
     Consequently, there are three possible combinations that you should
     consider:


     - World Access and STAR;


     - World Access and WorldxChange; and



     - World Access, STAR and WorldxChange.

<PAGE>   16




     Unless stated otherwise, information provided in this joint proxy
     statement/prospectus assumes completion of the WorldxChange merger. Where
     appropriate, we have indicated where information pertaining to World Access
     and STAR does not give effect to the merger with WorldxChange.


Q:   WHAT DO I NEED TO DO NOW?


A:   Mail your signed proxy card in the enclosed return envelope as soon as
     possible so that your shares will be represented at your meeting. If you do
     not include instructions on how to vote your properly signed proxy, your
     shares will be voted for approval of the proposals on which you are able to
     vote.


Q:   WHAT DO I DO IF I WANT TO CHANGE MY VOTE?


A:   If you are a World Access stockholder and want to change your vote, send
     the secretary of World Access a later-dated, signed proxy card before the
     World Access meeting or attend the meeting in person. You may also revoke
     your proxy by sending written notice to the secretary of World Access
     before the meeting. World Access stockholders who have signed the voting
     agreements described in this document may not revoke the proxies they gave
     in the voting agreements.



     If you are a STAR stockholder and want to change your vote, send the
     secretary of STAR a later-dated, signed proxy card before the STAR meeting
     or attend the meeting in person. You may also revoke your proxy by sending
     written notice to the secretary of STAR before the meeting. STAR
     stockholders who have signed the voting or conversion agreements described
     in this document may not revoke the proxies they gave in the voting or
     conversion agreements.


Q:   IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
     SHARES FOR ME?

A:   Your broker will vote your shares only if you provide instructions on how
     to vote by following the information provided to you by your broker.

Q:   SHOULD I SEND IN MY STAR STOCK CERTIFICATES NOW?

A:   No. After the STAR merger is completed, World Access will send STAR
     stockholders written instructions for exchanging their STAR stock
     certificates for the applicable STAR merger consideration.


Q:   WHEN DO YOU EXPECT THE STAR MERGER AND THE PT-1 ASSET SALE TO BE COMPLETED?



A:   World Access and STAR are working toward completing the STAR merger, and
     STAR is working to complete the PT-1 asset sale, as quickly as possible.
     World Access and STAR hope to complete the STAR merger, and STAR hopes to
     complete the PT-1 asset sale, in the third calendar quarter of 2000.



Q:   WILL I RECOGNIZE AN INCOME TAX GAIN OR LOSS ON THE STAR MERGER OR THE PT-1
     ASSET SALE?



A:   STAR stockholders will not recognize gain or loss for federal income tax
     purposes if the STAR merger is completed, except that STAR stockholders
     will recognize gain or loss with respect to cash received in lieu of
     fractional shares or cash received after the exercise of appraisal rights.
     If World Access elects to pay cash as part of the STAR merger
     consideration, STAR stockholders will recognize their gain realized for
     federal income tax purposes, but only up to the amount of cash received,
     and any such recognized gain may be taxed as ordinary income. STAR
     stockholders will not recognize gain or loss for federal income tax
     purposes from the PT-1 asset sale if PT-1 is sold for cash. STAR
     stockholders are urged to consult their own tax advisors to determine their
     particular tax consequences.


Q:   AM I ENTITLED TO APPRAISAL RIGHTS?


A:   If you are a STAR stockholder who will receive a combination of World
     Access common stock and cash, other than cash paid in lieu of fractional
     shares, under the STAR merger agreement and do not vote for the adoption of
     the STAR merger agreement, you may have the right under Delaware law to
     dissent from the STAR merger and request an appraisal of the fair value of
     your STAR common


                                        3
<PAGE>   17


     stock. In order to preserve this right, you must follow the procedures
     discussed on page 67 of this joint proxy statement/prospectus. STAR
     stockholders are not entitled to appraisal rights in connection with the
     PT-1 asset sale. If you are a World Access stockholder, you are not
     entitled to appraisal rights under Delaware law.



                             QUESTIONS AND ANSWERS


                         ABOUT THE WORLDXCHANGE MERGER



Q:  WHAT IS THE WORLDXCHANGE MERGER?



A:   The boards of directors of World Access and WorldxChange have voted to
     combine the businesses of World Access and WorldxChange. To combine the
     companies, WorldxChange will merge with a subsidiary of World Access, with
     such subsidiary continuing as a wholly-owned subsidiary of World Access.
     After the WorldxChange merger, the percentage in voting power of the
     combined companies will be as follows:

</TABLE>



Q:   WHAT WILL WORLDXCHANGE SHAREHOLDERS RECEIVE IN THE WORLDXCHANGE MERGER?



A:   When the WorldxChange merger is completed, WorldxChange shareholders will
     receive 0.6583 shares of World Access common stock in exchange for each
     share of WorldxChange common stock, including each share of WorldxChange
     common stock into which shares of WorldxChange preferred stock are deemed
     converted immediately prior to the completion of the WorldxChange merger.
     Assuming a value of $9.00 per share of World Access common stock, World
     Access will issue a total dollar value of approximately $270.0 million to
     WorldxChange shareholders in consideration in the WorldxChange merger.



     World Access will not issue fractional shares. World Access will issue cash
     in lieu of fractional shares based on the average closing sale price of
     World Access common stock over a ten-trading day period ending at the close
     of trading on the second trading day prior to the date of the completion of
     the WorldxChange merger.



     The following table shows the approximate number of shares of World Access
     common stock and amount of cash instead of fractional shares that a
     WorldxChange shareholder will receive for WorldxChange common stock held or
     received upon conversion of preferred stock upon completion of the
     WorldxChange merger. This table assumes an average closing price for the
     World Access common stock of $9.00 for the purpose of calculating the
     amount of cash paid instead of fractional shares and the value of total
     consideration received.

Q:   WHAT ARE THE STAR MERGER AND THE PT-1 ASSET SALE?



A:   This joint proxy statement/prospectus contains information regarding an
     additional merger, the STAR merger, and the sale by STAR of the assets of
     its wholly-owned subsidiary, PT-1. The completion of the WorldxChange
     merger does not depend on the completion of the STAR merger or the PT-1
     asset sale, and the completion of the STAR merger or the PT-1 asset sale
     does not depend on the


                                        4
<PAGE>   18


     completion of the WorldxChange merger. Consequently, there are three
     possible combinations that you should consider:



     - World Access and WorldxChange;


     - World Access and STAR; and


     - World Access, STAR, and WorldxChange.


Q:   WHAT DO I NEED TO DO NOW?


A:   If you are a World Access stockholder, you should mail your signed proxy
     card in the enclosed return envelope as soon as possible so that your
     shares may be represented at the World Access meeting. If you do not
     include instructions on how to vote your properly signed proxy, your shares
     will be voted for approval of the proposals with regard to which you are
     entitled to vote.


Q:   WHAT DO I DO IF I WANT TO CHANGE MY VOTE?

A:   If you are a World Access stockholder and you want to change your vote,
     send the secretary of World Access a later-dated, signed proxy card before
     the meeting or attend the meeting in person. You may also revoke your proxy
     by sending written notice to the secretary of World Access before the
     meeting. World Access stockholders who have signed voting agreements may
     not revoke the proxies given by them in the voting agreement.


Q:   SHOULD I SEND IN MY WORLDXCHANGE STOCK CERTIFICATES NOW?



A:   No. After the WorldxChange merger is completed, World Access will send
     WorldxChange shareholders written instructions for exchanging their
     WorldxChange stock certificates for World Access stock certificates.



Q:   WHEN DO YOU EXPECT THE WORLDXCHANGE MERGER TO BE COMPLETED?



A:   World Access and WorldxChange are working toward completing the
     WorldxChange merger as quickly as possible. World Access and WorldxChange
     hope to complete the merger in the third calendar quarter of 2000.



Q:   WILL I RECOGNIZE AN INCOME TAX GAIN OR LOSS ON THE WORLDXCHANGE MERGER?



A:   WorldxChange shareholders will not recognize gain or loss for federal
     income tax purposes if the WorldxChange merger is completed, except that
     WorldxChange shareholders will recognize gain or loss with respect to cash
     received in lieu of fractional shares or cash received after the exercise
     of dissenters' rights. Holders of WorldxChange preferred stock may have
     additional tax consequences upon payment of the accrued and unpaid
     dividends on such stock as part of the WorldxChange merger. WorldxChange
     shareholders are urged to consult their own tax advisors to determine their
     particular tax consequences.


Q:   AM I ENTITLED TO APPRAISAL OR DISSENTERS' RIGHTS?


A:   If you are a WorldxChange shareholder, you may be entitled to dissenters'
     rights under California law. In order to preserve this right, you must
     follow the procedures discussed on page 113 of this joint proxy
     statement/prospectus. If you are a World Access stockholder, you are not
     entitled to appraisal rights under Delaware law.

     In 1999, World Access adopted a strategy designed to build on its
U.S.-based carrier service business and position itself to become a significant
provider of bundled voice, data and Internet services to retail business
customers located in selected European countries. World Access believes that the
European telecommunications market has become extremely fragmented in recent
years due primarily to deregulation and significant forecasted growth. As a
result, World Access expects that a significant consolidation of carriers
operating in Europe will occur in the next few years, not unlike that which
occurred in the United States telecommunications market during the late 1980's
and 1990's. The strategy of World Access is to establish a pan-European
telecommunications network and gain significant market share during this period
of consolidation by playing a leading role in the consolidation of this market.
To execute its strategy, World Access intends to aggressively pursue the
acquisition of businesses, with a


                                        6
<PAGE>   20

particular emphasis on those that provide retail services to small and medium
sized businesses operating in Europe.

     To support its retail services strategy, World Access acquired FaciliCom
International in December 1999. FaciliCom had invested in excess of $200.0
million over the past few years to establish an inter-country network in the
U.S. and 13 European countries. Although the vast majority of its revenues were
derived from transporting traffic for other carriers, similar to World Access'
base business, FaciliCom's network was readily capable of supporting retail
traffic and related services. This acquisition effectively doubled the size of
World Access' carrier service revenue, provided a significant amount of European
originated revenue and lowered the combined company's costs of terminating
international traffic in Europe.

     World Access entered 2000 with an annual revenue base in excess of $1.0
billion, almost all of which relates to transporting traffic for other carriers.
In February 2000, World Access acquired NETnet International, a subsidiary of
Long Distance International. NETnet, which had revenues of approximately $83.0
million in 1999, provides an array of telecommunications services to small and
medium sized business customers in Austria, France, Germany, Italy, Norway,
Spain, Sweden, Switzerland and the United Kingdom.

     The acquisition of NETnet gave World Access approximately 20,000 retail
customers, an experienced retail sales force and a foundation for the offering
of bundled voice, data and Internet services to its targeted market in Europe.
It also provided World Access with a strong retail trade name, which World
Access currently expects to use for all of its retail product offerings in
Europe. World Access hopes to substantially improve the historical gross margins
realized by NETnet by terminating selected NETnet traffic over the World Access
network and eliminating the costs of redundant network facilities.

     With the addition of NETnet, World Access now has an annual revenue base in
excess of $1.1 billion, approximately eight percent of which is derived from
retail services and the remainder from its base carriers' carrier business. Of
the total revenue, approximately 60% results from traffic originated in the
United States and 40% from traffic originated in Europe.


     In February 2000, World Access entered into agreements to merge with STAR
and WorldxChange. These two companies are expected to increase World Access'
annual revenue base by an additional $1.0 billion, approximately $400.0 million
of which will be generated from traffic originated in Europe. After completing
these mergers, World Access revenue mix will be approximately 20% retail and 80%
carriers' carrier.



     In addition to an improved retail/carrier revenue mix, the STAR and
WorldxChange mergers are expected to provide World Access with substantial
benefits in the areas of network coverage, network capacity and reduced
operating costs. In combining the networks and operations of all three
companies, World Access expects that there will be redundant switching
equipment, facilities and personnel. World Access expects to eliminate these
redundant assets and significantly reduce the headcount of the combined company
in an effort to realize cost synergies. As a result, World Access expects to
record a one-time restructuring charge upon the completion of the STAR and
WorldxChange mergers. The restructuring charge is expected to include the
write-down of switching and transmission equipment taken out of service, the
write-off of certain leasehold improvements, a provision for lease commitments
remaining on certain facilities and equipment taken out of service, employee
termination benefits and other related costs. Although World Access has not yet
finalized the restructuring program, it is expected to be approved in its final
form and adopted immediately following the mergers. World Access has not yet
determined the actual restructuring charge to be recorded but expects that it
will be significant.


     The STAR and WorldxChange mergers will give World Access substantial
operations and network capacity in Germany and the United Kingdom, which
represent the two largest segments of the European telecommunications market.
World Access expects to leverage these operations to further grow its retail
business in these two key countries. WorldxChange has also developed
Internet-based information management systems that incorporate all key aspects
of retail telecommunications services, including

                                        7
<PAGE>   21

billing, fraud protection and customer care. These information systems are
expected to serve as the platform for supporting all retail operations conducted
by World Access in Europe.


     Although the STAR and WorldxChange mergers are expected to provide
significant benefits to World Access, they also dramatically increase the
business and financial risks World Access must overcome to execute its strategy.
World Access, STAR and WorldxChange all have a history of significant net
operating losses, and World Access is expected to assume approximately $300.0
million in debt upon the consummation of the two mergers. You should carefully
review the risk factors contained in this joint proxy statement/prospectus.


     The sale of $70.0 million of Series A Preferred Stock, the sale of $158.1
million of common stock in private placement transactions and approximately
$275.0 million of gross cash proceeds from the sale of two equipment businesses
in April 2000 have significantly enhanced the financial strength of World Access
and improved its liquidity. World Access believes that existing cash balances of
approximately $400.0 million, available borrowings under a $100.0 million
revolving bank line of credit and additional cash expected to be generated from
the sale of remaining World Access Equipment Group assets will provide World
Access with sufficient financial resources to support the cash requirements of
World Access, STAR and WorldxChange for at least the next 12 months.

     In June 2000, World Access agreed to acquire all or a majority of TelDaFax
AG, a leading provider of bundled fixed line, wireless, Internet and e-commerce
services to business and residential customers in Germany. In 1999, TelDaFax
produced revenue and earnings before interest, taxes, depreciation and
amortization of approximately $329.0 million and $9.0 million, respectively. As
of March 31, 2000, TelDaFax had approximately $50.0 million in cash and
marketable securities, with essentially no debt.

     TelDaFax currently operates nine switches and has 170 interconnection
points within Germany. They are also in the process of deploying a
2,800-kilometer fiber optic network between selected German cities that will
provide the foundation for future growth in their service offerings. The
TelDaFax network, together with the existing network assets of World Access and
Star, will give World Access one of the most extensive telecommunication
networks in Germany. In addition, TelDaFax has a dedicated sales force that
consists of 350 direct sales personnel and over 1,000 non-exclusive sales
agents.

     World Access stockholders will receive a separate proxy
statement/prospectus on the TelDaFax acquisition in the near future. The
financial statements of TelDaFax have been included in this joint proxy
statement/prospectus and considered in the preparation of the Unaudited Pro
Forma Financial Information contained herein.

                           SUMMARY OF THE STAR MERGER


THE STAR MERGER


     In the STAR merger, STAR will merge with and into a subsidiary of World
Access and become a subsidiary of World Access. In the STAR merger, World Access
will issue a total of approximately 22.9 million shares of World Access common
stock to the STAR stockholders if it elects to pay all of the STAR merger
consideration in stock and will assume approximately $75.0 million of STAR's
debt.



     World Access and STAR believe the STAR merger will permit World Access and
STAR to realize several benefits, including:



     - potential cost savings and synergies from integrating the systems and
       operations of both companies;



     - creation of a diversified geographic and product market position for the
       combined companies;


     - combining operations to take advantage of potential growth in bundled
       voice, data and Internet services to key international markets; and

     - strengthening international network presence and wholesale customers.


     Despite the anticipated benefits, the parties will incur significant merger
related expenses, in addition there are potential risks to the STAR merger,
including:



     - profitability may not be achieved;



     - increased cash flow may be necessary to fund capital expenditures and
       meet obligations on outstanding indebtedness;



     - market share may decrease, and the companies may face pricing pressures
       if they are not able to compete successfully with other
       telecommunications firms; and



     - government regulatory policies may increase pricing pressures, delay
       payments, change foreign currency values and decrease demand for the
       companies' services and products.



CONDITIONS TO COMPLETION OF THE STAR MERGER



     World Access' and STAR's respective obligations to complete the STAR merger
are subject to the satisfaction or waiver of closing conditions.



     The conditions that must be satisfied or waived before World Access is
obligated to complete the STAR merger include the following:



     - no material adverse effect may occur with respect to STAR;



     - holders of fewer than 1% of the shares of STAR common stock shall have
       exercised dissenters' rights of appraisal under Delaware law; and



     - STAR must complete the PT-1 asset sale to Counsel for net cash proceeds
       of at least $120.0 million or complete the sale of PT-1 to a party other
       than Counsel for net cash proceeds of at least $150.0 million pursuant to
       an agreement reasonably satisfactory to World Access.



     Any of the closing conditions can be waived by the party that is not
obligated to complete the STAR merger if the condition is not satisfied.



     If either World Access or STAR waives any condition, World Access and STAR
will each consider the facts and circumstances at that time and determine
whether a resolicitation of proxies from stockholders is appropriate. The boards
of directors of STAR and World Access will resolicit stockholder approval of the
STAR merger if either company waives a material closing condition that the
boards believe a reasonable investor would consider important when deciding to
approve the STAR merger.

                         SUMMARY OF THE PT-1 ASSET SALE



THE PT-1 ASSET SALE



     World Access is not obligated to complete the STAR merger unless STAR sells
the assets of its wholly-owned subsidiary, PT-1, for net cash proceeds of at

will be satisfied if STAR sells the assets of PT-1 to Counsel for net cash
proceeds of at least $120.0 million under the terms of the PT-1 asset sale
agreement.



     STAR and PT-1 have agreed to sell the assets of PT-1 to Counsel for $150.0
million, subject to adjustment based on increases in the accounts payable or
receivable of PT-1 and the increases or decreases in the net worth of the assets
of PT-1 on the closing date.



     If the STAR stockholders approve the PT-1 asset sale but do not approve the
STAR merger, STAR intends to complete the PT-1 asset sale.

complete the PT-1 asset sale if the condition is not satisfied.



     If either STAR or Counsel waives any closing conditions, STAR and Counsel
will each consider the facts and circumstances at that time and determine
whether a resolicitation of proxies from stockholders is appropriate. The STAR
board of directors will resolicit stockholder approval of the PT-1 asset sale if
either STAR or Counsel waives a material closing condition that the STAR board
of directors believe a reasonable investor would consider important when
deciding to approve the PT-1 asset sale.

Access. In the WorldxChange merger, World Access will issue a total of
approximately 29.8 million shares of World Access common stock to the
WorldxChange shareholders and will assume approximately $225.0 million of
WorldxChange's debt.



     World Access believes the WorldxChange merger will provide several
potential benefits, including:



     - strengthening international presence through adding WorldxChange's global
       communications network and presence in Europe and the Pacific Rim to

OPINION OF WORLD ACCESS' FINANCIAL ADVISORS



     In deciding to approve the WorldxChange merger, World Access' board of
directors considered an opinion from its financial advisor, Donaldson, Lufkin &
Jenrette Securities Corporation, as to the fairness to World Access, from a
financial point of view, of the consideration to be paid by World Access
pursuant to the WorldxChange merger agreement.



INTERESTS OF DIRECTORS, OFFICERS AND SHAREHOLDERS IN THE WORLDXCHANGE MERGER



     When considering the recommendations of World Access' and WorldxChange's
boards of directors, you should be aware that certain World Access and
WorldxChange directors, officers and shareholders have interests in the
WorldxChange merger that are different from, or are in addition to, all other
stockholders of World Access and shareholders of WorldxChange. These interests
include the acceleration of stock options and severance payments upon completion
of the WorldxChange merger, as well as the right of WorldxChange's Chairman of
the Board to serve as a World Access director or appoint someone else to do so.



ANTITRUST AND DOMESTIC AND FOREIGN REGULATORY APPROVALS REQUIRED TO COMPLETE THE
WORLDXCHANGE MERGER



     The WorldxChange merger is subject to antitrust laws. World Access,
WorldxChange and other related parties have made the required filings with the
Department of Justice, the Federal Trade Commission, the German Cartel Office
and Australian and New Zealand foreign investment review boards. However, the
companies are not permitted to complete the WorldxChange merger until the


                                       16
<PAGE>   30


applicable waiting periods have expired or terminated. The Department of Justice
and the Federal Trade Commission granted an early termination of the waiting
period, effective April 6, 2000. No further action under the U.S. antitrust laws
is required, as long as the WorldxChange merger is completed prior to April 6,
2001. The Department of Justice, the Federal Trade Commission, the German Cartel
Office, and the Australian and New Zealand foreign investment review boards, as
well as other foreign regulatory agencies or governments, state or private
persons, may challenge the WorldxChange merger at any time before or after its
completion.



     The WorldxChange merger is also subject to state and federal
telecommunications regulatory approvals. World Access and WorldxChange have
filed applications or notices, as required, in 48 states and at the FCC. The FCC
has approved the WorldxChange merger.

(2) Gross profit is exclusive of depreciation and amortization related to the
    services network which is shown separately below.


(3) EBITDA from continuing operations as used in this joint proxy
    statement/prospectus is earnings (loss) before net interest expense
    (income), income taxes, foreign exchange gains or losses, depreciation and
    amortization and is presented because World Access believes that such
    information


                                       18
<PAGE>   32


    is commonly used in the telecommunications industry as one measure of a
    company's operating performance and historical ability to service debt.
    EBITDA from continuing operations is not determined in accordance with
    generally accepted accounting principles, is not indicative of cash provided
    by operating activities, should not be used as a measure of operating income
    and cash flows from operations as determined under generally accepted
    accounting principles and should not be considered in isolation or as an
    alternative to, or to be more meaningful than, measures of performance
    determined in accordance with generally accepted accounting principles.
    EBITDA, as calculated by World Access, may not be comparable to similarly
    titled measures reported by other companies and could be misleading unless
    all companies and analysts calculated EBITDA in the same manner. The
    following table reconciles our loss from continuing operations to EBITDA
    from continuing operations and EBITDA from continuing operations before
    restructuring charge:

(2) The pro forma net income or loss per share assumes that STAR and CEO
    Telecommunications, Inc., which STAR acquired in a pooling of interests
    transaction on November 30, 1997, were C-corporations for all periods
    presented.


(3) See Note 2 of Notes to Consolidated Financial Statements set forth in STAR's
    annual report on Form 10-K for the fiscal year ended December 31, 1999 and
    incorporated by reference herein, for an explanation of the method used to
    determine the number of shares used in computing basic and diluted income
    (loss) per common share and pro form basic and diluted income (loss) per
    common share.


(4) EBITDA from continuing operations as used in this joint proxy
    statement/prospectus is earnings (loss) before net interest expense
    (income), income taxes, foreign exchange gains or losses, depreciation and
    amortization and is presented because STAR believes that such information is
    commonly used in the telecommunications industry as one measure of a
    company's operating performance and historical ability to service debt.
    EBITDA from continuing operations is not determined in accordance with
    generally accepted accounting principles, is not indicative of cash provided
    by operating activities, should not be used as a measure of operating income
    and cash flows from operations as determined under generally accepted
    accounting principles and should not be considered in isolation or as an
    alternative to, or to be more meaningful than, measures of performance
    determined in accordance with generally accepted accounting principles.
    EBITDA, as calculated by STAR, may not be comparable to similarly titled
    measures reported by other companies and could be misleading unless all
    companies and analysts calculate EBITDA in the same manner.


(5) Includes assets financed with capital leases, notes and vendor financing
    arrangements.


(6) Does not include wholesale billed minutes of use from T-One Corporation, a
    former subsidiary of STAR, prior to the year ended December 31, 1997.
    Includes wholesale billed minutes of use attributable to ALLSTAR Telecom,
    formerly know as United Digital Network, Inc., a subsidiary of STAR, for all
    years presented.


(7) Represents wholesale gross call usage revenue per billed minute. Amounts
    exclude other revenue related items such as finance charges. This data does
    not include wholesale billed minutes of use from T-One prior to the year
    ended December 31, 1997.

operations to EBITDA from continuing operations (in thousands):

                                  RISK FACTORS



     IN ADDITION TO THE OTHER INFORMATION CONTAINED OR INCORPORATED BY REFERENCE
IN THIS JOINT PROXY STATEMENT/PROSPECTUS, YOU SHOULD CAREFULLY CONSIDER THE
FOLLOWING RISK FACTORS IN DECIDING WHETHER TO VOTE FOR OR EXERCISE DISSENTERS'
RIGHTS WITH RESPECT TO THE MERGERS.



RISK FACTORS CONCERNING THE COMBINED COMPANY IN CONNECTION WITH THE MERGERS



THE FAILURE TO SUCCESSFULLY INTEGRATE THE COMPANIES BY MANAGING THE SIGNIFICANT
CHALLENGES OF INTEGRATING THREE COMPANIES MAY RESULT IN THE COMBINED COMPANY NOT
ACHIEVING THE ANTICIPATED BENEFITS OF THE MERGERS.



     The mergers require the integration in a timely manner of three companies
that previously operated independently. The companies will have to combine
workforces and integrate offices. The combination of the companies may require
some employees to relocate as part of this process. World Access expects that
after the mergers it will, as a result of the combined company's increased size
and requirements, be able to consolidate its purchasing and obtain more
favorable prices from suppliers. However, the combined company's ability to do
so may be limited by changes in the purchasing power or practices of its
competitors and other market dynamics. The integration of the networks of STAR
and WorldxChange into the World Access network will be a complex, time consuming
and expensive process that may disrupt the combined company's business if not
completed in a timely and efficient manner. No assurance can be given that the
combined company will be able to successfully integrate its operations without
encountering difficulties or experiencing the loss of key employees, extended
network downtime, or that the cost savings and synergies expected from
integration will be realized. The combined companies may incur significant
expenses in consolidating each company's network and operations. The
consolidation of the company will require substantial attention from management.
These expenses and the diversion of management's attention, as well as any
difficulties encountered in the transition and integration process, could have a
significant negative effect on the combined company's revenues, levels of
expenses and stock price and could damage relationships with key customers and
employees.



THE COMBINED COMPANY MAY NOT BE ABLE TO ACHIEVE PROFITABILITY.



     After giving effect to the mergers and certain other transactions, the
combined companies would have had total losses of approximately $72.8 million
from continuing operations for the three months ended March 31, 2000 and $0.62
per diluted share as compared to the $0.57 loss per diluted share from
continuing operations of World Access for the same period on a stand alone
basis. The significance of these losses could cause the combined company's stock
price to drop and prohibit the combined company from achieving profitability.



THE FIXED EXCHANGE RATIOS IN EACH OF THE MERGERS MAY REQUIRE STAR OR
WORLDXCHANGE TO CLOSE THE STAR MERGER OR THE WORLDXCHANGE MERGER, RESPECTIVELY,
AT A TIME WHEN THE VALUE OF THE WORLD ACCESS SHARES TO BE RECEIVED BY THE STAR
STOCKHOLDERS OR THE WORLDXCHANGE SHAREHOLDERS, RESPECTIVELY, IS SUBSTANTIALLY
LESS THAN IT WAS ON THE DATES THE STAR MERGER AGREEMENT AND THE WORLDXCHANGE
MERGER AGREEMENT WERE ENTERED INTO.



     Neither WorldxChange nor STAR has the right under their respective merger
agreements to decline to close the merger if World Access's stock price falls
below any particular level. This could result in WorldxChange and STAR
shareholders receiving World Access shares worth substantially less than these
shares were worth at the time the merger agreements were entered into.



     The value of the World Access stock on February 11, 2000, which is the
original date the exchange ratios were agreed upon, was $22.875. As an example
of World Access' stock price volatility, the following

common stock on the Nasdaq National Market during the indicated months.

</TABLE>



THE COMBINED COMPANY'S INCREASED FINANCIAL LEVERAGE WILL SUBJECT IT TO
SIGNIFICANT OPERATING AND FINANCIAL RESTRICTIONS.



     Immediately after the completion of the mergers, the combined company will
have a higher degree of financial leverage than prior to the mergers. At March
31, 2000, World Access had $414.0 million of long-term debt and a total debt to
equity ratio of approximately 39.8%, STAR had approximately $43.1 million of
long-term debt and approximately $270.1 stockholders' equity and WorldxChange
had $71.4 million of long-term debt and negative stockholders' equity. Based on
World Access' balance sheet at March 31, 2000 reflecting the combination of
World Access, STAR and WorldxChange, the combined company would have had
long-term debt of $524.0 million and a total debt to equity ratio of 38.1%.



     The combined company's indebtedness could have serious negative
consequences. For example, it could:



     - limit the combined company's ability to obtain additional financing for
       working capital, capital expenditures or other purposes or make it
       difficult to obtain such financing on favorable terms;



     - require the combined company to dedicate a substantial portion of its
       cash flow from operations to service payments on its debt, which will
       reduce the funds that would otherwise be available for operations and
       future business opportunities; and



     - make it difficult for the combined company to meet its debt service
       requirements or force the combined company to modify its operations if
       there is a substantial decrease in operating income and cash flows or an
       increase in expenses.



     World Access anticipates that the combined company's 2000 debt service
payments will be approximately $415.0 million exclusive of any obligation to
redeem its outstanding debt securities. If the combined company is unable to
generate sufficient cash flow or to otherwise obtain funds necessary to meet its
obligations, or if the combined company does not comply with the various
covenants under its indebtedness, the combined company will be in default under
the terms of that debt. If the combined company defaults, the holders of
indebtedness can accelerate the maturity of the indebtedness that is owed to
them, which could cause defaults under the combined company's other
indebtedness.


                                       30
<PAGE>   44


IF THE MERGERS ARE APPROVED, THE VOTING INTERESTS OF CURRENT WORLD ACCESS
STOCKHOLDERS WILL BE SUBSTANTIALLY DILUTED IN THE COMBINED COMPANY DUE TO THE
ISSUANCE OF COMMON STOCK TO STAR AND WORLDXCHANGE STOCKHOLDERS.



     The completion of the STAR merger and WorldxChange merger will result in a
substantial dilution of the voting and equity interests of current World Access
stockholders. Following the completion of the mergers and assuming that World
Access elects to use its stock as consideration in the STAR merger to the
maximum extent possible, the current World Access stockholders will:



          (i) own shares representing approximately 67.0% of the combined
     company's total voting power and



          (ii) own 68.0% of the total number of outstanding shares of the
     combined company's common stock on a fully diluted basis.



     If only the STAR merger is completed, assuming that World Access elects to
use its stock as consideration in the STAR merger to the maximum extent
possible, the current World Access stockholders will:



          (i) own shares representing approximately 82.0% of the combined
     company's total voting power after completion of the STAR merger and



          (ii) own 83.0% of the total number of outstanding shares of the
     combined company's common stock on a fully diluted basis after completion
     of the STAR merger.



If only the WorldxChange merger is completed, the current World Access
stockholders will:



          (i) own shares representing approximately 77.0% of the combined
     company's total voting power after completion of the WorldxChange merger
     and



          (ii) own 78.0% of the total number of outstanding shares of the
     combined company's common stock on a fully diluted basis after completion
     of the WorldxChange merger.



IF THE SALE OF PT-1 IS NOT COMPLETED PRIOR TO THE CLOSING OF THE STAR MERGER, IF
STAR DOES NOT RECEIVE NET CASH PROCEEDS OF AT LEAST $120.0 MILLION FROM THE SALE
OF THE ASSETS OF PT-1 TO COUNSEL, OR IF STAR DOES NOT RECEIVE NET CASH PROCEEDS
OF AT LEAST $150.0 MILLION FROM THE SALE OF PT-1 TO ANOTHER PURCHASER, THE STAR
MERGER MAY NOT CLOSE.



     If STAR sells the assets of PT-1 to Counsel for net cash proceeds of less
than $120.0 million, or to a purchaser other than Counsel for net cash proceeds
of less than $150.0 million, then World Access does not have to complete the
STAR merger. There can be no assurance that STAR will complete the PT-1 asset
sale to Counsel for net cash proceeds of at least $120.0 million, or to any
other purchaser for net cash proceeds of at least $150.0 million, as required by
the STAR merger agreement. In the event that the STAR merger is not completed,
STAR may face significant costs associated with the failed STAR merger,
including a termination fee of $14.0 million, and will need to obtain additional
capital. STAR is not certain that it will be able to raise additional capital on
favorable terms or at all.


                                       31
<PAGE>   45


     While STAR believes it will complete the PT-1 asset sale to Counsel, the
completion of the PT-1 asset sale is subject to closing conditions contained in
the PT-1 asset sale agreement. There can be no assurance that all such
conditions will be satisfied. In addition, the PT-1 asset sale agreement
provides that the PT-1 asset sale agreement can be terminated under certain
circumstances, including by PT-1 or Counsel if the PT-1 asset sale is not
completed on or before August 31, 2000.



     STAR cannot guarantee that the PT-1 asset sale will be completed. If the
PT-1 asset sale agreement is terminated and STAR does not enter into an
alternative definitive agreement for the sale of PT-1, World Access does not
have to complete the STAR merger. If the PT-1 asset sale agreement is
terminated, STAR may face significant costs associated with the failed PT-1
asset sale, including a termination fee of $5.85 million. In addition, PT-1 will
be required to pay the termination fee if the PT-1 asset sale agreement is not
approved by the required vote of the stockholders of STAR and STAR sells the
assets of PT-1 to another party within one year of the failed stockholder vote.



     In addition, the completion of the PT-1 asset sale to Counsel for net cash
proceeds of at least $120.0 million is dependent, in part, on the results of a
final audit to be conducted after the close of the PT-1 asset sale. There can be
no assurance that the net value of the assets of PT-1 as of the closing of the
PT-1 asset sale will be greater than or equal to the net value of the assets as
of December 31, 1999 or that there will be no increases in the accounts payable
or receivable of PT-1, which may result in net cash proceeds of less than $120.0
million for the PT-1 asset sale.



DECREASED CASH FLOW MAY LIMIT THE COMBINED COMPANY'S ABILITY TO CONTINUE TO MAKE
CAPITAL EXPENDITURES FOR THE ACQUISITION AND DEVELOPMENT OF ITS INTERNATIONAL
TELECOMMUNICATIONS NETWORK, WHICH IS NECESSARY TO BE COMPETITIVE IN THIS
INDUSTRY.



     The combined company will need to enhance and expand its network and build
out its telecommunications network infrastructure in order to maintain a
competitive position and to meet the increasing demands for service quality,
capacity and competitive pricing. The combined company will need to raise
additional capital from equity or debt sources if its cash flow from operations
is insufficient to meet its capital expenditure and working capital
requirements. If the combined company's available cash flow substantially
decreases as a result of lower telecommunications prices or for other reasons,
the combined company may have limited ability to continue to make capital
expenditures for the acquisition and development of its international
telecommunications network. If cash flow from operations is not sufficient to
satisfy the combined company's capital expenditure requirements, additional debt
or equity financing or other sources of capital may not be available to meet the
combined company's requirements.



RISK FACTORS CONCERNING THE COMBINED COMPANY'S BUSINESS OPERATIONS



THE COMBINED COMPANY MAY NOT BE ABLE TO LEASE TRANSMISSION FACILITIES AT
HISTORICAL RATES, WHICH MAY NEGATIVELY IMPACT THE COMBINED COMPANY'S
PROFITABILITY AND CAUSE A LOSS OF CUSTOMERS.



     As a result of the mergers, the combined company will be able to utilize
World Access' network facilities, STAR's network facilities and WorldxChange's
network facilities. However, the combined company's future profitability will be
based in part upon its ability to transmit long distance telephone calls over
transmission facilities, also referred to in the industry as network facilities,
leased from others on a cost-effective basis. Also, a substantial portion of the
combined company's transmission capacity will be obtained on a variable, per
minute and short-term basis, subjecting the combined company to the possibility
of unanticipated price increases and service cancellations. Since the combined
company will not generally have long-term arrangements for the purchase or
resale of international long distance services, and since rates fluctuate
significantly over short periods of time, the combined company's gross margins
are subject to significant fluctuations. Competitive pricing pressures for these
facilities may also negatively impact the combined company in the longer term.


                                       32
<PAGE>   46


IF THE COMBINED COMPANY CANNOT SUCCESSFULLY ENTER THE DATA TRANSMISSION
BUSINESS, IT MAY LOSE CUSTOMERS AND INCUR SIGNIFICANT EXPENSES.



     The combined company's experience in providing data transmission services
to date has been limited and, consequently, the combined company can provide no
assurance that it will be successful in the data transmission business. The
combined company's ability to successfully enter the data transmission business
will depend upon, among other things, its ability to:



     - select new equipment and software and integrate these into its network;



     - hire and train qualified personnel; and



     - enhance its billing, back-office and information systems to accommodate
       data transmission services and customer acceptance of its service
       offerings.



     In providing data transmission services, the combined company will be
dependent upon vendors for assistance in the planning and deployment of its data
product offerings, as well as ongoing training and support. If the combined
company is not successful at entering the data transmission business, it may
suffer a loss of customers and incur significant expenses without any increase
in income to offset such expenses.



TECHNICAL DIFFICULTIES WITH OR FAILURES IN THE COMBINED COMPANY'S
TELECOMMUNICATIONS NETWORK COULD RESULT IN DISSATISFIED CUSTOMERS AND LOST
REVENUE.



     In Europe, there are a number of different protocols for data transmission.
The combined company's network will need to be able to handle all of these
protocols, which will pose technical difficulties. Technical difficulties with
or failures in the combined company's telecommunications network could result in
dissatisfied customers and lost revenue. For example, a failure in a portion of
the combined company's network could prevent the combined company from
delivering telephone calls initiated by its customers. Additionally, technical
difficulties with the network could cause the loss of call detail record
information, which is the basis for the combined company's ability to process
and substantiate customer billings. Components of each companies' networks have
failed in the past, which have resulted in lower billing collections. The
combined company can provide no assurance that similar or other failures or
technical difficulties will not occur in the future, which could result in the
loss of customers and revenue.



WORLD ACCESS MAY NOT BE ABLE TO INCREASE ITS NETWORK CAPACITY AT A RATE THAT IS
COMMENSURATE WITH THE DEMANDS OF ITS CUSTOMER BASE.



     World Access is currently in the process of expanding its network, and as
it expands its network and the volume of its network traffic, its cost of
revenues will increasingly consist of fixed costs arising from the ownership and
maintenance of switches and fiber optic cables. These costs may increase, and
its operating margins may decrease. If its traffic volume were to decrease, or
fail to increase to the extent expected or necessary to make efficient use of
its network, its costs as a percentage of revenues would increase significantly,
which could significantly decrease the revenues of its business operations.



     In addition, World Access' business depends in part on its ability to
obtain transmission facilities on a cost-effective basis. World Access may not
be able to obtain sufficient transmission facilities or access to undersea fiber
optic cable on economically viable terms. World Access' failure to obtain
telecommunications facilities that are sufficient to support its network traffic
in a manner that ensures the reliability and quality of its telecommunications
services could increase World Access' operational costs, as well as cause a loss
of customers due to poor quality or unreliable service.



THE COMBINED COMPANY'S BUSINESS IS DEPENDENT UPON THE INTEGRITY AND EXPANSION OF
ITS NETWORK AND TELECOMMUNICATIONS FACILITIES, WHICH PUTS ITS OPERATIONS AT RISK
TO OUTSIDE FORCES BEYOND ITS CONTROL.



     Any system or network failure that interrupts the combined company's
operations could cause the loss of customers, a reduction in revenues or a
decrease in the combined company's stock price. The combined


                                       33
<PAGE>   47


company's operations are dependent on its ability to successfully expand its
network and integrate new and emerging technologies and equipment into its
network, which are likely to increase the risk of system failure and to cause
strain upon the networks. The combined company's operations also depend on its
ability to protect its hardware and other equipment from damage from natural
disasters such as fires, floods, hurricanes and earthquakes, other catastrophic
events such as civil unrest, terrorism and war and other sources of power loss
and telecommunications failures. The combined company's cannot be certain that
its switches will not become disabled in the event of an earthquake, power
outage or otherwise. A network failure or a significant decrease in telephone
traffic as a result of a natural or man-made disaster could have a material
adverse effect on the combined company's relationships with its customers, its
revenues and its operating results.



THE COMBINED COMPANY MAY BE UNABLE TO MANAGE EFFECTIVELY WORLD ACCESS' RECENT
RAPID GROWTH AND THE RAPID GROWTH PLANNED FOR THE COMBINED COMPANY, WHICH MAY
ADVERSELY AFFECT THE QUALITY OF THE COMBINED COMPANY'S PRODUCTS AND SERVICES AND
ITS ABILITY TO RETAIN KEY PERSONNEL.



     World Access' rapid growth from recent acquisitions and the expansion of
its operations has placed significant demands on its resources. In addition,
World Access expects that its expansion into foreign countries will lead to
increased financial and administrative demands, such as:


     - increased operational complexity associated with expanded network
       facilities;

     - administrative burdens associated with managing an increasing number of
       foreign subsidiaries and relationships with foreign partners; and

     - expanded treasury functions to manage foreign currency risks.


     If World Access, and the combined company after the mergers, is unable to
manage its growth effectively, the quality of its products and services and its
ability to retain key personnel could be adversely affected. To successfully
manage its future growth, the combined company must effectively manage its
operational, financial and management information systems, as well as its
employees.



RISK FACTORS CONCERNING THE COMPANIES' FINANCIAL CONDITION



WORLD ACCESS MAY SUSTAIN MATERIAL LIABILITY AS A RESULT OF STOCKHOLDER SUITS.



     Following World Access' announcement in January 1999 regarding earnings
expectations for the quarter and year ended December 31, 1998 and the subsequent
decline in the price of World Access common stock, a number of stockholders
filed class action complaints against World Access. The plaintiffs allege
violations of the federal securities laws and have requested an unspecified
amount of damages in their complaints and have not quantified their claim at the
time this joint proxy statement/prospectus was printed. World Access may have to
pay substantial damages if the plaintiffs are successful in their actions.



RESTRICTIONS UNDER THE WORLD ACCESS CREDIT FACILITY MAY REQUIRE WORLD ACCESS TO
MAKE BUSINESS DECISIONS THAT ARE ADVERSE TO WORLD ACCESS' LONG TERM INTERESTS
AND THE INTERESTS OF ITS STOCKHOLDERS.



     Restrictions under the World Access $100.0 million revolving line of credit
facility may require World Access to make business decisions that are adverse to
World Access' long term interests and to the interests of the holders of its
common stock. For example, World Access generally must obtain the lenders'
consent and sometimes prepay a portion of the outstanding debt under the credit
facility before it can issue securities, enter into acquisitions for cash or
securities, dispose of its assets or incur additional debt. World Access also
must maintain certain operating ratios and achieve specified financial
thresholds.



     Upon a default under World Access' credit facility, the lenders may require
World Access to immediately repay the entire amount outstanding under the credit
facility. If World Access cannot repay these borrowings, it may need to seek the
protection of the federal bankruptcy laws to continue operating its business,
and possibly sell its assets, which would have a material adverse effect on its
business and its relationships with customers, suppliers and employees. Even if
World Access is able to repay all amounts


                                       34
<PAGE>   48


owed under the credit facility, the payment of the amount outstanding under the
credit facility could result in a loss in liquidity. In addition, in the event
of a default under the credit facility that World Access does not cure, the
lenders could foreclose on the collateral securing the loans, which would result
in the lenders owning and having effective control over World Access' operations
and possibly in the sale of World Access' assets, which would have a material
adverse effect on World Access' business and its relationships with customers,
suppliers and employees.



IF STAR'S LENDERS DO NOT EXTEND THE DUE DATE FOR CERTAIN DEBT, OR IF THEY SUE TO
COLLECT CERTAIN DEBTS PRIOR TO COMPLETING THE PT-1 ASSET SALE, STAR COULD BECOME
INSOLVENT OR BE FORCED TO FILE FOR BANKRUPTCY.



     STAR is subject to certain restrictions under its financing arrangements,
including its financing arrangement with WorldCom Network Services, Inc. If STAR
violates any restrictions under its financing arrangements, STAR's lenders may
accelerate payment of the amounts STAR owes them. If STAR's lenders do not
extend the due date for STAR's debt or if STAR's lenders sue to collect on any
of STAR's debt, it could force STAR to file for bankruptcy or reorganize its
business.



     If STAR violates any restrictions under its receivables sale agreement with
RFC, RFC may declare an event of default and no longer purchase receivables from
STAR. If RFC does not continue to purchase STAR's receivables, STAR may be
deprived of needed liquidity. RFC can refrain from purchasing additional
receivables from STAR if STAR is in default under any other financing
arrangement.



     STAR has entered into promissory notes with WorldCom Network Services in
the amounts of $56.0 and up to $30.0 million, both of which are currently due on
August 31, 2000. In addition, STAR and certain of its subsidiaries owe Nortel
Networks, Inc. approximately $35 million. STAR intends to seek extensions on a
month to month basis from WorldCom Network Services to permit the PT-1 asset
sale to close and is working to obtain payment terms from Nortel. If STAR
commits a breach of the terms of the STAR merger agreement which results in
World Access having the right to terminate the STAR merger agreement, WorldCom
Network Services can accelerate payment of the outstanding balance. If STAR is
unable to obtain an extension from WorldCom Network Services and WorldCom
Network Services seeks to collect its debt, or if Nortel seeks to collect the
sum STAR and its subsidiaries owes to it, STAR and certain of its subsidiaries
may need to seek the protection of the federal bankruptcy laws to continue
operating its business, unless the sale of PT-1 is completed before these debts
are sought to be collected.



     STAR's anticipated financing arrangement with World Access provides for a
mutually agreeable initial advance but no such advance has been made, nor have
any other advances been made despite STAR's request. There can be no assurance
that World Access will provide financing to STAR. If World Access does provide
financing to STAR, such financing would be due if the STAR merger agreement was
terminated or if any terms of the financing were breached.



     There can be no assurance that STAR will not breach any restrictions under
its financing arrangements, that it will not breach the terms of the STAR merger
agreement or that if STAR enters into a financing arrangement with World Access,
that World Access will agree to make additional advances to STAR. STAR cannot
predict what actions its lenders will take if it is out of compliance with any
restrictions under any of its financing arrangements or under the STAR merger
agreement.



IF WORLDXCHANGE'S LENDERS ACCELERATE PAYMENT OF THE AMOUNTS WORLDXCHANGE OWES
THEM, WORLDXCHANGE COULD BECOME INSOLVENT OR BE FORCED TO FILE FOR BANKRUPTCY.



     WorldxChange is subject to certain restrictions under its financing
arrangements, including its financing arrangement with Foothill Capital
Corporation. If WorldxChange violates any restrictions under its financing
arrangements, its lenders may accelerate payment of the amounts it owes them. If
the lenders accelerate payment on any of WorldxChange's debt, it could force
WorldxChange to file for bankruptcy or reorganize its business. Under
WorldxChange's financing arrangements, if WorldxChange commits a breach of the
terms of these arrangements, WorldxChange's lenders can accelerate payment of
their obligations. There can be no assurance that WorldxChange will not breach
any of its financing


                                       35

arrangements. WorldxChange cannot predict what actions its lenders will take if
it is out of compliance with any restrictions under any of its financing
arrangements.



WORLDXCHANGE WILL NOT HAVE SUFFICIENT CASH FLOW FROM ITS BUSINESS TO PAY ITS
DEBT, AND UNLESS THE WORLDXCHANGE MERGER IS COMPLETED BEFORE OCTOBER 1, 2000,
WORLDXCHANGE WILL NEED TO RAISE ADDITIONAL CAPITAL TO PAY, OR WILL NEED TO
RESTRUCTURE, ITS DEBT OBLIGATIONS, WHICH CANNOT BE ASSURED.



     The amount of WorldxChange's outstanding debt is large compared to its cash
flow. As of March 31, 2000 WorldxChange had:



        - total consolidated debt of approximately $204.5 million; and



        - stockholders' deficit of approximately $51.8 million.



     Of WorldxChange's total consolidated debt, approximately $162.0 million is
due over the next 12 months. The earliest of the maturity dates for this debt is
October 1, 2000. WorldxChange will not generate enough cash from its operations
to meet these obligations. If the WorldxChange merger is not completed by the
earliest maturity of these obligations, WorldxChange will need to raise
additional capital to pay, or will need to restructure, a substantial portion of
these obligations. No assurance can be given that additional capital will be
raised or that such obligations can or will be restructured.



DUE TO STAR'S LARGE AMOUNT OF DEBT PAYMENTS, STAR WILL NOT HAVE SUFFICIENT CASH
FLOW FROM ITS INDEPENDENT BUSINESS OPERATIONS TO PAY ITS DEBT AND STAR MAY NEED
TO RAISE ADDITIONAL CAPITAL TO PAY, OR WILL NEED TO RESTRUCTURE, ITS DEBT
OBLIGATIONS IF THE PT-1 ASSET SALE IS NOT COMPLETED, WHICH CANNOT BE ASSURED.



     The amount of STAR's outstanding debt is large compared to its cash flow
and the net book value of its assets. STAR is required to make significant
payments under its outstanding debt. As of March 31, 2000, STAR had:



        - total consolidated debt of approximately $179.0 million, including
          $25.9 million outstanding under its receivables sale arrangement with
          RFC and $56.0 million under its financing arrangement with WorldCom
          Network Services which was entered into on April 12, 2000; and



        - stockholders' equity of approximately $270.1 million.



     The WorldCom debt is currently due August 31, 2000 and STAR will seek month
to month extensions of this debt to permit the STAR merger to close.



     The following chart shows the interest and principal payments due on all of
STAR's currently outstanding debt for each of the next five fiscal years,
assuming STAR's lenders do not require early payment of the amounts due under
its credit arrangements. Also, because the interest rates under some of its
credit arrangements are based upon variable market rates, the amount of these
interest payments could fluctuate in the future.

     Due to the large amount of these principal and interest payments, STAR will
not generate enough cash from its operations to meet these obligations. In
addition, because of the large amount of STAR's debt and the restraints on its
cash flow, STAR has experienced difficulty paying trade debts as they

become due. STAR expects that the proceeds it receives from the sale of the
assets of PT-1 will provide it with sufficient capital to continue its
operations and service its debt. However, there can be no assurance that the
PT-1 asset sale will close, that STAR will find an alternative buyer for PT-1 or
that the proceeds STAR receives from the PT-1 asset sale will be sufficient. If
the PT-1 asset sale is not completed, STAR will need to raise additional capital
to pay its debts, or will need to restructure a substantial amount of these
obligations. No assurance can be given that additional capital will be raised or
that such obligations can or will be restructured.



WORLD ACCESS RELIES ON MCI WORLDCOM FOR A SUBSTANTIAL AMOUNT OF ITS GROSS
PROFITS AND THE TERMINATION OF WORLD ACCESS' CARRIER SERVICE AGREEMENT WITH MCI
WORLDCOM COULD SIGNIFICANTLY DECREASE ITS REVENUES AND GROSS PROFITS.



     World Access entered into a Carrier Service Agreement with MCI WorldCom
under which MCI WorldCom purchases international long distance services from
World Access on a wholesale basis. World Access recorded approximately $53.0
million of revenue and related gross profit of $18.0 million during the first
quarter of 2000. This represented approximately 21.0% and 56.0% of World Access'
total revenue and gross profit, respectively. Termination of the service
agreement, or any reduction in the services provided, could significantly
decrease World Access' revenues and profits, particularly in the carrier
services business. MCI WorldCom Network Services is obligated to purchase from
World Access at least $25.0 million a month of such services, provided the
services are of acceptable quality and the rates quoted are at least equal to
the rates WorldCom Network Services is obtaining from other third party
providers. The service agreement is for a one-year term but automatically renews
each month, subject to a one year termination notice.



RISK FACTORS CONCERNING THE COMPANIES' INDUSTRY



THE COMPANIES' RELIANCE ON INTERNATIONAL SALES IS SIGNIFICANT AND COULD RESULT
IN LOST REVENUE AND INCREASED COSTS BECAUSE OF INTERNATIONAL REGULATORY CHANGES,
POLITICAL AND ECONOMIC INSTABILITY AND DIFFICULTY IN COLLECTION EFFORTS.



     Non-U.S. sales represented approximately 4.8% of World Access' total sales
in the year ended December 31, 1999, approximately 11.7% of STAR's total sales
in the year ended December 31, 1999 and approximately 25.5% of WorldxChange's
total sales in the year ended December 31, 1999. After the mergers, the combined
company intends to increase its international sales. The companies international
sales are subject to inherent risks, including:


     - changes in regulatory requirements, tariffs or other barriers;

     - difficulties in staffing and managing foreign operations;

     - long payment cycles;

     - unstable political and economic environments;


     - potentially adverse tax consequences of international tax laws; and



     - fluctuations in foreign currency values.



THE COMBINED COMPANY CANNOT ASSURE YOU THAT ITS PLANNED ENTRY INTO THE INTERNET
AND DATA BUSINESS IN EUROPE WILL BE SUCCESSFUL DUE TO THE LEVEL OF COMPETITION
AND THE COMBINED COMPANY'S LACK OF EXPERIENCE IN THIS NEW MARKET.



     The market for Internet connectivity and related services is extremely
competitive. The combined company's primary competitors will include other
Internet service providers that have a significant national or international
presence, but soon may also include competition from traditional
telecommunications carriers that expand into the market for Internet services.
Many of these carriers have substantially greater resources, capital and
operational experience than the combined company will have. The combined


                                       37
<PAGE>   51


company will require substantial additional capital to make investments in its
Internet operations, and may not be able to obtain that capital on favorable
terms or at all.



     Even if the combined company is able to establish and expand its Internet
business, it will face numerous risks that may adversely affect the operations
of its Internet business. These risks include:



     - competition in the market for Internet services;



     - its ability to adapt and react to rapid changes in technology related to
       the Internet;



     - vulnerability to unauthorized access, computer viruses and other
       disruptive problems;



     - adverse regulatory developments; and



     - difficulties managing the growth of its Internet business, including the
       need to enter into agreements with other providers of infrastructure
       capacity and equipment and to acquire other Internet service providers
       and Internet-related businesses on acceptable terms.



AS THE COMBINED COMPANY EXPANDS ITS FOCUS ON RETAIL CUSTOMERS AND EMERGING
CARRIERS, ITS LEVEL OF UNCOLLECTIBLE DEBT MAY INCREASE.



     In the companies' experience, a greater percentage of the revenues
generated by retail customers and from emerging carriers has been uncollectible
as compared to revenues generated by sales to established wholesale carriers and
large international carriers. Therefore, since the percentage of World Access'
revenues after the mergers derived from retail operations and from sales to
emerging carriers will increase as a result of the mergers, its level of
uncollectible debt may increase, which would result in lower revenues and
profits. In addition, the combined company may expend considerable resources to
collect receivables from customers who fail to make timely payments.



DELAYS AND INCONSISTENCIES IN IMPLEMENTATION OF THE WORLD TRADE ORGANIZATION
AGREEMENT AND OTHER COMPETITIVE DIRECTIVES MAY SLOW DOWN THE RATE OF THE
COMBINED COMPANY'S EXPANSION IN SOME FOREIGN COUNTRIES



     Under the World Trade Organization Agreement, the U.S. and 68 other
countries agreed to open their telecommunications markets to competition and
foreign ownership effective February 5, 1998. These World Trade Organization
member countries, which have increased to 72, represent approximately 90% of
worldwide telecommunications traffic. Although the World Trade Organization
Agreement has been implemented, to some degree, by most of the 72 signatory
countries, some signatory countries have not yet fully implemented their World
Trade Organization commitments. The combined company's ability to expand its
operations internationally will be limited if any signatory country to the World
Trade Organization Agreement fails to implement its obligations on a timely
basis.



     The national governments of the European Union member states were required
to pass legislation to liberalize the telecommunications markets within their
countries to implement European Commission directives. Most of the member states
have now implemented the required legislation. The legislation and/or its
implementation have, in certain circumstances, imposed significant obstacles on
the ability of carriers to proceed with the licensing process. These barriers
include requirements that carriers:


     - post significant bonds or make significant capital commitments to build
       infrastructure;

     - complete extensive application documentation; and

     - pay substantial license fees.


     Implementation has also been slow in certain member states as a result of
their failure to dedicate the resources necessary to have a functioning
regulatory body in place. These factors and slow implementation of legislation
in connection with deregulation of telecommunications services could slow down
the combined company's rate of expansion and increase the cost of such
expansion.

GOVERNMENT REGULATORY POLICIES AND INDUSTRY CONSOLIDATION IN EUROPE MAY DECREASE
PROFIT MARGINS AND INCREASE PRICING PRESSURES IN THE COMBINED COMPANY'S INDUSTRY
AND DECREASE DEMAND FOR SERVICES AND PRODUCTS.



     The companies expect that government regulatory policies, including the
Telecommunications Act of 1996, are likely to continue to have a major impact on
the pricing of both existing and new public network services and possibly
accelerate the entrance of new competitors and consolidation of the industry. In
addition, industry consolidation, especially in Europe, may decrease profit
margins. These trends may decrease demand for the combined company's services
and products that support these services. Lower prices may affect the cost
effectiveness of the combined company's deployment of public network services.
User uncertainty regarding future policies may also decrease demand for the
combined company's telecommunications products and services.



FOREIGN GOVERNMENTS MAY ATTEMPT TO PREVENT THE COMBINED COMPANY FROM CONDUCTING
ITS BUSINESS AND FROM EXPANDING INTO THE FOREIGN COUNTRY.



     Governments of many countries exercise substantial influence over various
aspects of the telecommunications market. In some cases, the government owns or
controls companies that are or may become the combined company's competitors or
on which the combined company may depend for required interconnections to local
telephone networks and other services. Accordingly, government actions in the
future could block or impede the combined company's operation of its business.



     World Access desires to expand the combined company's foreign operations as
these markets increasingly permit competition. The nature, extent and timing of
the combined company's foreign operations, however, will be determined, in part,
by the actions taken by foreign governments to permit competition and the
response of incumbent carriers to these efforts. The regulatory authorities in
these countries may not provide the combined company with practical
opportunities to compete in the near future, or at all, and the combined company
may not be able to take advantage of any such liberalization in a timely manner.



RECENT FEDERAL COMMUNICATIONS COMMISSION ACTIONS MAY ADVERSELY AFFECT THE
COMBINED COMPANY'S OPERATIONS AND REVENUES BY INCREASING COMPETITION, WHICH MAY
INCREASE PRICING PRESSURES AND DECREASE DEMAND FOR THE COMBINED COMPANY'S
SERVICES.



     Recent Federal Communications Commission rulemaking orders and other
actions have lowered the entry barriers for new carriers and resale
international carriers by streamlining the processing of new applications and by
eliminating the international settlements policy for arrangements with foreign
carriers that lack market power and on other selected routes. In addition, the
Federal Communications Commission's rules implementing the World Trade
Organization Basic Telecommunications Agreement presume that competition will be
advanced by the U.S. entry of carriers and resale carriers from World Trade
Organization member countries, thus further increasing the number of potential
competitors in the U.S. market and the number of carriers which may also offer
end-to-end services. Increased competition may increase pricing pressures,
reduce the combined company's margins and decrease demand for the combined
company's services.



FEDERAL COMMUNICATIONS COMMISSION INTERVENTION REGARDING THE SETTLEMENT RATES
CHARGED BY FOREIGN CARRIERS MAY DISRUPT THE COMBINED COMPANY'S TRANSMISSION
ARRANGEMENTS TO CERTAIN COUNTRIES AND CAUSE THE COMBINED COMPANY TO SUFFER A
DECREASE IN REVENUES.



     The Federal Communications Commission recently has sought to reduce the
foreign routing costs of U.S. international carriers by prescribing maximum or
benchmark settlement rates which foreign carriers may charge U.S. carriers for
routing telecommunications traffic. The Federal Communications Commission's
benchmarks order was recently upheld by the U.S. Court of Appeals for the
District of Columbia circuit. The Federal Communications Commission's action may
reduce the combined company's settlement costs, although the costs of other U.S.
international carriers also may be reduced in a similar


                                       39
<PAGE>   53


fashion. The Federal Communications Commission has not stated how it will
enforce the new settlement benchmarks if U.S. carriers are unsuccessful in
negotiating settlement rates at or below the prescribed benchmarks. Any future
Federal Communications Commission intervention could disrupt the combined
company's transmission arrangements to certain countries or require the combined
company to modify its existing arrangements, which could cause the combined
company to suffer a decrease in revenues.



A RECENT FEDERAL COMMUNICATIONS COMMISSION ORDER DIRECTING ALL DOMESTIC
INTERSTATE CARRIERS TO DE-TARIFF THEIR SERVICES MAY ADVERSELY AFFECT THE
COMBINED COMPANY'S ABILITY TO COMPETITIVELY PRICE ITS SERVICE OFFERINGS.



     The Telecommunications Act of 1996 permits the Federal Communications
Commission to forbear enforcement of tariff provisions, which apply to all
interstate and international carriers, and the U.S. Court of Appeals for the
District of Columbia Circuit recently upheld the Federal Communications
Commission's order directing all domestic interstate carriers to de-tariff their
offerings. The Federal Communications Commission's order only applies to
domestic services. However, the Federal Communications Commission may forbear
its current tariff rules for U.S. international carriers such as the combined
company, or order these carriers to de-tariff their services. Any such Federal
Communications Commission action would likely afford non-dominant international
carriers greater flexibility in pricing service offerings, which would increase
the combined company's competition. The Federal Communications Commission
routinely reviews the contribution rate for various levels of regulatory fees,
including the rate for fees levied to support universal service, which fees may
be increased in the future for various reasons, including the need to support
the universal service programs mandated by the Telecommunications Act of 1996,
the total costs for which are still under review by the Federal Communications
Commission.



DELAYS AND COSTS INCURRED IN ACHIEVING COMPLIANCE WITH GOVERNMENT REGULATIONS
AND EVOLVING INDUSTRY STANDARDS FOR THE COMBINED COMPANY'S PRODUCTS COULD
ADVERSELY AFFECT ITS REVENUES.



     If the combined company's products fail to comply with the various existing
and evolving regulations and industry standards or if the combined company
experiences delays and incurs costs in achieving compliance with these
regulations and standards, revenues could materially decrease as a result of the
increased costs. The combined company'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
and services must comply with various regulations promulgated by the Federal
Communications Commission, as well as with standards established by Bell
Communications Research. Internationally, the combined company's products and
services must comply with standards established by telecommunications
authorities in various countries, as well as with recommendations of the
International Telecommunications Union. Any failure to comply with these
standards could result in a material reduction of revenue and a loss of
customers for the combined company.



RISK FACTORS CONCERNING THE COMBINED COMPANY'S COMMON STOCK



SIGNIFICANT VARIANCE IN THE COMBINED COMPANY'S QUARTERLY OPERATING RESULTS COULD
ADVERSELY AFFECT THE PRICE OF THE COMBINED COMPANY'S COMMON STOCK.



     In future quarters, the combined company's results of operations may fail
to meet the expectations of market analysts and investors, which may adversely
affect the price of its common stock. World Access' quarterly operating results
have varied significantly in the past, and the combined company's quarterly
operating results are expected to do so in the future. World Access' revenues,
costs and expenses have fluctuated significantly in the past and are likely to
continue to fluctuate significantly in the future as a result of numerous
factors. The combined company's revenues in any given period can vary due to
factors such as:


     - call volume fluctuations, particularly in regions with relatively high
       per-minute rates;

     - the addition or loss of major customers, whether through competition or
       merger;

                                       40
<PAGE>   54


     - the loss of economically beneficial routing options for the termination
       of traffic; and



     - technical difficulties with or failures of portions of its network that
       impact its ability to provide service to or bill customers.



     The combined company's cost of services and operating expenses in any given
period can vary due to factors such as:



     - fluctuations in rates charged by carriers to terminate traffic;


     - increases in bad debt expense and reserves;

     - the timing of capital expenditures, and other costs associated with
       acquiring or obtaining other rights to switching and other transmission
       facilities;


     - changes in sales incentive plans; and


     - costs associated with changes in staffing levels of sales, marketing,
       technical support and administrative personnel.


     In addition, the combined company's operating results can vary due to
factors such as:


     - changes in routing due to variations in the quality of vendor
       transmission capability;


     - the amount of, and the accounting policy for, return traffic under
       operating agreements;


     - actions by domestic or foreign regulatory entities;


     - the level, timing and pace of the combined company's expansion in
       international and retail markets; and


     - general domestic and international economic and political conditions.


     Further, World Access obtains a substantial portion of its transmission
capacity on a variable, per minute and short-term basis. Therefore, World Access
may experience unanticipated price increases and service cancellations. Since
World Access does not generally have long-term arrangements for the purchase or
resale of long distance services, and since rates fluctuate significantly over
short periods of time, World Access' gross margins may also fluctuate
significantly over short periods of time.



     In response to competitive pressures or new product and service
introductions, the combined company may take certain pricing or marketing
actions that could materially adversely affect its quarterly operating results.
World Access currently bases its expense levels, in part, on its expectations of
future sales. If future sales levels are below expectations, then the combined
company may be unable to adjust spending sufficiently in a timely manner to
compensate for the unexpected sales shortfall.



     Accordingly, you should not rely upon period-to-period comparisons of
operating results as an indication of future performance. In addition, the
operating results of any quarterly period are not indicative of results that you
should expect for a full fiscal year. Historically, World Access has generated a
disproportionate amount of its operating revenues toward the end of each
quarter, making precise prediction of revenues and earnings particularly
difficult and resulting in risk of variance of actual results from those
forecast at any time.

                                   PROPOSAL 1



                    THE MERGER BETWEEN WORLD ACCESS AND STAR



     This section of the joint proxy statement/prospectus describes the proposed
merger between World Access and STAR. This proposal is for consideration by the
World Access stockholders and the STAR stockholders, voting separately. The
completion of the STAR merger is conditioned on the sale of PT-1 by STAR. Unless
World Access waives this condition, World Access will be merging with STAR minus
its PT-1 operations if the STAR merger is completed.



BACKGROUND OF THE STAR MERGER



     During the first quarter of 1999, the STAR board of directors and members
of its management began searching for additional capital at a time when STAR's
core business margins were declining as a result of increased competition. In
addition, STAR was incurring significant capital costs in connection with the
expansion of its business into Germany and the development of its retail long
distance operations. During this time period, STAR engaged Goldman Sachs Credit
Partners LP, Kaufman Bros., L.P., Lehman Brothers, Morgan Stanley Dean Witter
and Deutsche Bank Securities Inc. to pursue a possible high yield bond offering
and to provide financial advice on strategic mergers. STAR concluded that it
would not raise sufficient capital from a high yield bond offering.



     During this same period, STAR also consulted with Goldman Sachs, Kaufman
Bros., Lehman Brothers, Morgan Stanley and Deutsche Bank about the feasibility
of spinning off its European operations, the possibility of the sale of stock of
one or more of STAR's subsidiaries and raising senior subordinated debt. STAR
determined that it could not pursue these transactions because the
telecommunications market conditions were not favorable and STAR lacked
sufficient capital.



     STAR received several acquisition proposals in the last quarter of 1999 for
STAR's German operations. These proposals were not considered attractive by the
STAR board of directors because the sale of STAR's German operations would have
provided additional cash but did not fit with STAR's strategy to diversify and
improve its business mix.



     In the late fall of 1999, STAR was approached by World Access, which was
aware of STAR's search for a strategic transaction. STAR was unable to discuss a
transaction with World Access at that time because it was subject to an
exclusive negotiating agreement with a third party. On December 20, 1999, after
the exclusive negotiating agreement had expired, STAR and World Access announced
the execution of a letter of intent under which World Access would acquire all
of STAR's outstanding capital stock in exchange for shares of common stock of
World Access, and possibly cash, valued at approximately $10.50 per share of
STAR common stock. The letter also called for World Access to provide STAR with
a short-term loan when a definitive agreement was signed. During the due
diligence period, World Access concluded that STAR would require substantial
capital to achieve its business objectives, including capital expenditures
necessary to expand its network, employ new technologies and enter foreign
markets. World Access also concluded that STAR's operating losses could not be
stemmed as easily as World Access had first thought and it would require a
significant capital investment to return STAR to profitability. World Access and
STAR both maintained strong networks but both parties determined that there
would be a continuing need for capital to fund expansions into new geographic
areas and in order to enter into new operating agreements.



     Representatives of World Access and STAR met to renegotiate the terms of
the STAR merger. STAR's management had taken steps to improve cash flow,
including through the reduction of capital


                                       42
<PAGE>   56


expenditures, but in part due to capital constraints, had not been able to
return STAR to profitability or positive cash flow. World Access determined that
the initial offer it had made to STAR was too high because of STAR's financial
condition and future capital requirements. STAR considered World Access' revised
proposal and determined that the revised offer was in the best interests of the
STAR stockholders because of STAR's operating results, capital requirements and
prospects.



     On February 2, 2000, the parties agreed to reprice the STAR merger, and
World Access indicated that STAR was free to shop for better offers from other
bidders. Under the revised terms, World Access agreed to pay between $7.50 and
$8.00 for each outstanding share of STAR common stock. In addition, World Access
agreed in principle to provide STAR with a short-term loan, subject to STAR's
and World Access' agreement on the definitive terms of the short-term loan.
Based on this agreement, the parties issued a joint press release announcing the
repricing and worked to finalize the STAR merger agreement.



     During the period between December 20, 1999 and February 2, 2000, STAR did
not receive a superior proposal from another potential competing bidder. Prior
to signing a definitive agreement, the STAR board of directors was free to and
did seek out other proposals. The STAR board of directors met on February 7,
2000 and considered the revised proposal at length. Given STAR's rising debt and
cash shortage and the lack of superior offers, management was instructed to
continue negotiations with World Access.



     On February 8, 2000, the board of directors of World Access met to receive
a report from management regarding the status of the merger discussions with
STAR, including the results of World Access' due diligence investigation of STAR
and the resulting repricing of the transaction. On February 11, 2000, the board
of directors of World Access met again to consider the merger with STAR. At this
meeting, management reviewed, for the board of directors, the strategic reasons
for a business combination with STAR. Management and legal counsel described the
specific terms of the proposed STAR merger agreement. During this meeting,
Donaldson, Lufkin & Jenrette gave its oral opinion as to the fairness of the
consideration to be paid by World Access under the STAR merger agreement. The
board of directors also received summaries of the results of World Access' due
diligence investigation of STAR. The World Access board of directors unanimously
approved the STAR merger agreement and the transactions contemplated by the STAR
merger agreement and unanimously agreed to recommend its adoption to the
stockholders of World Access. On February 11, 2000, Donaldson, Lufkin & Jenrette
forwarded its written opinion regarding the fairness of the consideration to be
paid by World Access under the STAR merger agreement to the members of the board
of directors of World Access.



     On or about February 7, 2000 and February 11, 2000, the STAR board of
directors met to consider World Access' renegotiated proposal. The board
received an opinion from Deutsche Bank Securities Inc. that the proposal was
fair from a financial point of view to STAR and STAR's stockholders. The STAR
board of directors also received advice from Delaware legal counsel on its
obligations regarding its duty of care and its duty to exercise informed
business judgment.



     At the meeting held on February 11, 2000, the STAR board of directors
concluded that the STAR merger was fair to and in the best interests of STAR and
its stockholders. The STAR board of directors considered STAR's financial
condition, the decline in margins in its core business due to increased
competition and the significant capital required to diversify STAR's business
mix. The STAR board of directors voted to approve the STAR merger agreement and
the transactions contemplated by the STAR merger agreement and voted to
recommend that the stockholders of STAR vote for the approval and adoption of
the STAR merger agreement and the transactions contemplated by the STAR merger
agreement. In approving the STAR merger, the STAR board of directors considered
the potential benefits of the STAR merger, including all material business,
financial, legal and market factors, and the risks associated with the STAR
merger discussed below under the heading "STAR's reasons for the STAR merger."



     Beginning on or about May 18, 2000, STAR began discussions with World
Access regarding the PT-1 asset sale agreement. STAR sought World Access'
approval of the terms of the PT-1 asset sale agreement, as well as World Access'
consent to STAR's execution of the PT-1 asset sale agreement, as required by


                                       43
<PAGE>   57


the STAR merger agreement. On May 25, 2000, STAR received World Access' consent
to enter into the PT-1 asset sale agreement although World Access had not yet
determined whether the PT-1 asset sale agreement met the requirements of the
STAR merger agreement. On May 30, 2000, representatives of both STAR and World
Access met in Atlanta, Georgia to discuss the terms of the PT-1 asset sale
agreement in relation to the requirements of the STAR merger agreement. STAR and
World Access determined that an amendment to the STAR merger agreement was
necessary to adjust the amount of net cash proceeds that STAR was required to
obtain from the PT-1 asset sale and to modify certain other provisions of the
STAR merger agreement as more fully described in this joint proxy statement/
prospectus.



     On June 6, 2000, the STAR board of directors met to consider the proposal
to amend the STAR merger agreement. The STAR board of directors received advice
from Delaware legal counsel on its obligations regarding its duty of care and
its duty to exercise informed business judgment. The STAR and World Access board
of directors did not seek a new fairness opinion regarding the amendment to the
STAR merger agreement as the boards of directors determined that the terms of
the amendment did not differ materially from the original terms of the STAR
merger agreement. In addition, the STAR board of directors obtained a fairness
opinion from Kaufman Bros. regarding the PT-1 asset sale. The STAR board of
directors concluded that the amendment to the STAR merger agreement was fair to
and in the best interests of the stockholders of STAR. The STAR board of
directors considered the potential benefits of the amendment to the STAR merger
agreement, including the importance of completing the STAR merger for the
reasons discussed below under the heading "STAR's reasons for the STAR merger."
The STAR board of directors also considered the potential negative consequences
of the amendment to the STAR merger agreement also discussed below.



     On June 6, 2000, STAR entered into the PT-1 asset sale agreement with
Counsel. On June 7, 2000, STAR and World Access executed the amendment to the
STAR merger agreement and issued a joint press release announcing the amendment
to the STAR merger agreement.


WORLD ACCESS' REASONS FOR THE STAR MERGER


     In approving the STAR merger, the World Access board of directors
considered the potential benefits of the STAR merger and the risks associated
with the STAR merger. All material business, financial, legal and market factors
are discussed below. In view of the number and wide variety of factors
considered in connection with its evaluation of the STAR merger, the board of
directors did not consider it practicable to, nor did it attempt to, quantify or
otherwise assign relative weights to the material factors considered in reaching
its determination. The World Access board of directors viewed its position and
recommendation as being based on the totality of the information and factors
presented to and considered by it. In addition, individual directors may have
given different weight to different information and factors.



     The financial terms of the STAR merger.  The World Access board of
directors considered information concerning the business, earnings, operations,
financial condition and prospects of World Access and STAR, individually, on a
combined basis, and in conjunction with the WorldxChange merger. The board
determined to approve the STAR merger agreement and the transactions
contemplated by the STAR merger agreement based on its consideration of these
factors without taking into account the WorldxChange merger. The board also
considered the opinion of Donaldson, Lufkin & Jenrette Securities Corporation as
to the fairness to World Access, from a financial point of view, of the
consideration to be paid by World Access pursuant to the STAR merger agreement.



     Star's extensive facilities-based network.  The World Access board of
directors considered the approximately $350.0 million that STAR has invested in
its international network and the additional geographic coverage, connectivity
and capacity this network would bring World Access. The STAR network connects
more than 51 countries worldwide and includes 24 international gateway switches,
17 transoceanic cable systems and a North American fiber network that connects
30 cities. The board reviewed financial analyses prepared by World Access
management that estimated a range of gross margin improvement that could be
realized by redirecting selected World Access traffic over the STAR network


                                       44
<PAGE>   58


and redirecting selected STAR traffic over the World Access network. The board
determined that the World Access estimates were realistic and that based on the
financial analyses presented and their own business judgment, the cost savings
would be substantial.



     The board placed particular emphasis on the investments made by STAR in
recent years to implement its German network, including switching and
transmission equipment, cable connections between 23 German cities and related
operating licenses. The presence of the network and related infrastructure
within Germany was a significant factor in evaluating the STAR merger due to the
size of the German telecommunications market, the importance of this market to
World Access' future strategic plans and the ability of the network to
efficiently support retail service offerings.



     Star's established revenue base.  The World Access board of directors
considered the current revenue base of STAR, which consisted primarily of
approximately $350.0 million in U.S.-based carrier traffic and $150.0 million
from traffic originated in Germany. Of the German revenue, World Access
management estimated approximately 90% was related to carrier services and 10%
from retail services. The addition of this revenue base establishes World Access
as one of the largest providers of carrier services in the world and provides a
significant base within Germany to leverage future growth.



     Potential cost savings and synergies.  The board reviewed financial
analyses by World Access management that estimated a range of selling, general
and administrative cost savings that could be realized by combining World Access
and STAR, including the elimination of redundant switching centers, customer
care operations and corporate office functions. The board determined that the
World Access estimates were realistic and that based on the financial analyses
presented and their own business judgment, the cost savings would be
substantial.



     STAR's established customer base.  The World Access board of directors
considered the compatibility of STAR's established base of carrier customers
with World Access' existing customer base. STAR's customer base includes 14 of
the top 40 global carriers, the vast majority of which are complementary to
World Access' customer base. In particular, STAR does considerable business with
AT&T, Sprint and Qwest Communications, three global telecommunications
companies. World Access currently does not do significant business with these
companies and is optimistic that these and other STAR customer relationships can
be leveraged to provide incremental revenue and further cost reductions.



     Ability to accelerate plans to become a leading provider of bundled voice,
data and internet services to key European markets.  The World Access board of
directors considered the additional services offered by STAR, which would be
made available to current and future customers of World Access. Specifically,
the board considered the significant expansion of retail telecommunications
services available throughout Europe and the potential positioning of World
Access as one of the top long distance carriers in Germany.



     The World Access board of directors also considered the following material
risks associated with completing the STAR merger, but concluded that the
advantages of the STAR merger far outweighted the risks:



     - STAR's history of operating losses and negative cash flow, though the
       board felt that the spending plans and controls of World Access combined
       with the realization of margin improvement and cost savings as a result
       of the merger would eliminate these losses and negative cash flow within
       a one year period;



     - World Access' ability to service and repay STAR's outstanding debt and
       financial commitments, though this risk was significantly reduced as a
       result of the cancellation of STAR's participation in a China-U.S. cable
       consortium and WorldCom's agreement to convert approximately $90.0
       million of STAR trade debt into shares of World Access common stock upon
       consummation of the STAR merger; and


                                       45
<PAGE>   59


     - the risk that World Access would be unable to effectively integrate the
       technical operations, customers, suppliers and management of both STAR
       and WorldxChange and realize the margin and cost savings synergies noted
       above.



THE WORLD ACCESS BOARD OF DIRECTORS' RECOMMENDATION THAT STOCKHOLDERS APPROVE
THE STAR MERGER



     The World Access board of directors considered the advisability of the STAR
merger and believes that the terms of the STAR merger agreement and the
transactions contemplated thereby are fair to and in the best interests of the
stockholders of World Access. The World Access board of directors has
unanimously approved the STAR merger agreement and the transactions contemplated
by the STAR merger agreement. The World Access board of directors unanimously
recommends that the stockholders of World Access vote for the approval and
adoption of the STAR merger agreement and the transactions contemplated by the
STAR merger agreement.


STAR'S REASONS FOR THE STAR MERGER


     In approving the STAR merger, the STAR board of directors considered the
potential benefits of the STAR merger and the risks associated with the STAR
merger. All material business, financial, legal and market factors are discussed
below. After due deliberation, the STAR board of directors concluded that the
STAR merger was fair to and in the best interest of STAR and its stockholders
based on the following material factors:



     The financial condition of STAR.  The STAR board of directors examined the
current financial condition of STAR and determined that STAR was facing
significant cash restraints resulting in difficulty in meeting STAR's ongoing
obligations. STAR was experiencing substantial operating losses and negative
cash flow and its ability to implement its operating and business plans was
severely constrained by the absence of available capital. The STAR board of
directors noted that as of December 31, 1999 STAR had long term debt obligations
of $94.3 million and total debt obligations of $156.4 million. The STAR board of
directors also considered that STAR was unable to fund required future capital
expenditures needed to expand and maintain STAR's business. STAR's management
focused on minimizing losses and improving cash flow but it lacked the capital
necessary to implement a business plan designed to return STAR to profitability.
The STAR board of directors considered that all of these factors and STAR's debt
obligations created a substantial risk of insolvency and the need to seek
bankruptcy protection.



     Lack of financing alternatives.  During the first quarter of 1999, STAR
began to explore financing alternatives. The STAR board of directors engaged
financial advisors to examine STAR's options with respect to sources of
financing, including equity and debt financing. The STAR board of directors
determined that the necessary financing would not be available or would not be
available on acceptable terms.



     The potential cost savings and synergies.  The STAR board of directors
considered the potential cost savings and synergies that World Access and STAR
would achieve through the STAR merger. The STAR board of directors reviewed a
number of financial analyses prepared by World Access that estimated a range of
cost savings achievable through the STAR merger. The STAR board of directors
determined that the World Access estimates were realistic and that based on the
World Access analyses and their own business judgment, the cost savings would be
substantial. The STAR board of directors considered the following material
potential cost savings and synergies that would be achieved through the STAR
merger:



     - the combined technical operations would create a more efficient
       communications network than STAR's and World Access' networks on a
       stand-alone basis;



     - the combined company would have a geographically broader, more diverse
       network and savings could be achieved through the elimination of
       overlapping networks; and



     - STAR could combine its network monitoring operations with those of World
       Access, which would generate cost savings.


                                       46
<PAGE>   60


     Diversified geographic market position.  The STAR board of directors
considered that World Access' network coverage would complement STAR's existing
coverage. The STAR board of directors considered that STAR would obtain a
broader European presence through the combination of STAR's network assets and
licenses in Germany with World Access' existing operations.



     Diversified product and service offering.  The STAR board of directors
considered that the combined company would be in a position to offer a broader
array of services and products than STAR could individually. STAR was facing
declining profit margins in the wholesale business and STAR's efforts to enter
the retail market were encountering difficulty, in part due to capital
constraints. The combination with World Access would provide STAR with an
increased presence in foreign markets, expanded use of Internet based
technologies and expansion opportunities in selected retail markets, which the
STAR board of directors believed would increase stockholder value.



     Enhanced Management Strength.  The STAR board of directors considered that
the STAR merger would strengthen STAR's management team by providing additional
financial and technical expertise. The STAR board of directors noted that STAR
was facing difficulty filling key managerial positions and determined that the
STAR merger would obviate the need to fill certain key management positions and
would improve STAR's ability to recruit key personnel.



     The STAR board of directors also considered the following material risks
associated with completing the STAR merger, but concluded that the advantages of
the STAR merger far outweighed these risks:



     - the possibility that World Access would be unable to complete the STAR
       merger and the WorldxChange merger simultaneously;



     - the risk that World Access would be unable to effectively integrate the
       technical operations and management of both STAR and WorldxChange, or to
       effectively integrate future acquisitions considering the announced
       intention of World Access to make acquisitions;



     - the risk that World Access might not have sufficient funds available to
       finance the combined companies, though the STAR board of directors
       considered that at the time of its approval of the STAR merger, World
       Access had significant capital resources; and



     - overall risks inherent in the highly competitive telecommunications
       industry, but the STAR board of directors considered that the combined
       companies would be better able to withstand and respond to competitive
       risks.



     The above discussion of the information and factors considered by the STAR
board of directors sets forth the material factors considered by the STAR board
of directors. The STAR board of directors considered many factors when
evaluating the STAR merger agreement and the STAR merger. The STAR board of
directors did not quantify, rank or attempt to assign relative weights to the
factors considered in reaching its determination. In addition, the STAR board of
directors conducted an overall analysis of the above factors, including a
thorough discussion with and questioning of STAR's management. The STAR board of
directors also considered management's analysis of the STAR merger based on
information received from STAR's legal, financial and accounting advisors. The
STAR board of directors considered all these factors as a whole, and considered
the factors overall to be favorable to and to support its determination.



THE STAR BOARD OF DIRECTORS' RECOMMENDATION THAT STOCKHOLDERS APPROVE THE STAR
MERGER



     The STAR board of directors carefully considered the advisability of the
STAR merger and believes that the terms of the STAR merger agreement and the
transactions contemplated by the STAR merger agreement are fair to and in the
best interests of the stockholders of STAR. The STAR board of directors approved
the STAR merger agreement and the transactions contemplated by the STAR merger
agreement. The STAR board of directors recommends that the stockholders of STAR
vote for the approval and adoption of the STAR merger agreement and the
transactions contemplated by the STAR merger agreement.

OPINION OF WORLD ACCESS' FINANCIAL ADVISOR REGARDING THE STAR MERGER


     World Access asked Donaldson, Lufkin & Jenrette Securities Corporation in
its role as financial advisor, to render an opinion to the World Access board as
to the fairness, from a financial point of view, to World Access of the
consideration to be paid by World Access. On February 11, 2000, Donaldson,
Lufkin & Jenrette rendered an oral opinion to World Access' board of directors,
which was subsequently confirmed in writing as of the same date, to the effect
that, as of the date of the opinion, and based upon and subject to the
assumptions, limitations and qualifications set forth in the written opinion,
the consideration to be paid by World Access pursuant to the STAR merger
agreement was fair to World Access, from a financial point of view. The full
text of Donaldson, Lufkin & Jenrette's opinion is attached as Annex C to this
joint proxy statement/prospectus.



     Donaldson, Lufkin & Jenrette expressed no opinion as to the prices at which
STAR common stock or World Access common stock would actually trade at any time.
Donaldson, Lufkin & Jenrette's opinion did not address the relative merits of
the STAR merger and the other business strategies considered by the World Access
board of directors nor did it address the decision of the World Access board of
directors to proceed with the STAR merger. Donaldson, Lufkin & Jenrette's
opinion did not constitute a recommendation to any World Access stockholder as
to how such stockholder should vote on the STAR merger.



     World Access and STAR determined the consideration to be paid by World
Access in arm's length negotiations, in which Donaldson, Lufkin & Jenrette
advised World Access.



     World Access selected Donaldson, Lufkin & Jenrette as its financial advisor
because Donaldson, Lufkin & Jenrette is an internationally recognized investment
banking firm that has substantial experience providing strategic advisory
services. Donaldson, Lufkin & Jenrette was not retained as an advisor or agent
to the stockholders of World Access or any other person. As part of its
investment banking business, Donaldson, Lufkin & Jenrette is regularly engaged
in the valuation of businesses and securities in connection with mergers,
acquisitions, underwritings, sales and distributions of listed and unlisted
securities, private placements and valuations for corporate and other purposes.
World Access did not impose any restrictions or limitations upon Donaldson,
Lufkin & Jenrette with respect to the investigations made or the procedures
followed by Donaldson, Lufkin & Jenrette in rendering its opinion.



     In arriving at its opinion, Donaldson, Lufkin & Jenrette:



     - reviewed the draft dated February 26, 2000 of the merger agreement and
       assumed the final form of that agreement would not vary in any respect
       material to Donaldson, Lufkin & Jenrette's analysis;



     - reviewed financial and other information that was publicly available or
       furnished to it by World Access and STAR, including information provided
       during discussions with their respective managements, which included
       certain financial projections of each of World Access and STAR that were
       prepared by World Access' management;



     - compared certain financial and securities data of World Access and STAR
       with various other companies whose securities are traded in public
       markets;



     - reviewed the historical stock prices and trading volumes of the common
       stock of World Access and STAR;



     - reviewed prices paid in selected other business combinations; and



     - conducted other financial studies, analyses and investigations as
       Donaldson, Lufkin & Jenrette deemed appropriate for purposes of rendering
       its opinion.



     In rendering its opinion, Donaldson, Lufkin & Jenrette relied upon and
assumed the accuracy and completeness of all of the financial and other
information that was available to it from public sources, that was provided to
it by World Access and STAR or their respective representatives, or that was
otherwise reviewed by it. Donaldson, Lufkin & Jenrette relied upon the estimates
of the management of World Access of the operating synergies achievable as a
result of the STAR merger. Donaldson, Lufkin &

                                       48
<PAGE>   62


Jenrette also assumed that the financial projections of World Access and STAR
supplied to it were reasonably prepared on the basis reflecting the best
currently available estimates and judgments of the management of World Access as
to the future operating and financial performance of World Access and STAR. In
addition, Donaldson, Lufkin & Jenrette relied upon and assumed net cash proceeds
of $150.0 million from the sale of PT-1 by STAR. Donaldson, Lufkin & Jenrette
expressed no opinion with respect to such forecasts or the assumptions on which
they were based. Donaldson, Lufkin & Jenrette did not assume any responsibility
for making any independent evaluation or appraisal of the assets or liabilities
of World Access or for making any independent verification of any of the
information reviewed by Donaldson, Lufkin & Jenrette. Donaldson, Lufkin &
Jenrette also did not assume any responsibility for making any independent
investigation of any legal matters affecting World Access or STAR and assumed
the correctness of all legal advice given to each of them and to World Access'
board of directors, including advice as to the tax consequences of the STAR
merger. Donaldson, Lufkin & Jenrette assumed that the STAR merger would be
accounted for as a purchase under generally accepted accounting principles and
that it would qualify as a tax-free reorganization for U.S. federal income tax
purposes.



     Donaldson, Lufkin & Jenrette's opinion is necessarily based upon economic,
market, financial and other conditions as they existed on, and on information
available to Donaldson, Lufkin & Jenrette as of, the date of its opinion.
Donaldson, Lufkin & Jenrette states in its opinion that, although subsequent
developments may affect its opinion, Donaldson, Lufkin & Jenrette does not have
any obligation to update, revise or reaffirm its opinion.



SUMMARY OF FINANCIAL ANALYSES PERFORMED BY DONALDSON, LUFKIN & JENRETTE



     The following is a summary of the financial analyses Donaldson, Lufkin &
Jenrette presented to the World Access board of directors on February 11, 2000
in connection with the preparation of Donaldson, Lufkin & Jenrette's opinion. No
company or transaction Donaldson, Lufkin & Jenrette used in the analyses
described below is directly comparable to World Access, STAR or to the STAR
merger. In addition, mathematical analysis such as determining the mean or
median is not in itself a meaningful method of using selected company or
transaction data. The analyses Donaldson, Lufkin & Jenrette performed are not
necessarily indicative of actual values or future results, which may be
significantly more or less favorable than suggested by these analyses. The
information summarized in the tables which follow should be read in conjunction
with the accompanying text.



     For purposes of the following analyses, Donaldson, Lufkin & Jenrette (i)
used the February 9, 2000 closing price of the World Access common stock of
$22.88 per share and (ii) assumed net cash proceeds of $150.0 million from the
sale by STAR of PT-1. It should be understood that Donaldson, Lufkin & Jenrette
makes no prediction, and there can be no assurance, as to what the closing price
of World Access common stock or the net cash proceeds from the sale of PT-1 will
actually be.



1. CONSIDERATION PAID ANALYSIS



     Donaldson, Lufkin & Jenrette reviewed the consideration to be paid by World
Access pursuant to the STAR merger agreement. In reviewing the consideration to
be paid by World Access, Donaldson, Lufkin & Jenrette assumed an exchange ratio
of 0.3905, which represents the exchange ratio based on net cash proceeds from
the sale of PT-1 of $150.0 million.



2. COMPARABLE PUBLICLY TRADED COMPANY ANALYSIS



     Donaldson, Lufkin & Jenrette analyzed the market values and trading
multiples of selected publicly traded emerging multinational carriers that
Donaldson, Lufkin & Jenrette believed were reasonably


                                       49
<PAGE>   63


comparable to STAR based on business and certain financial characteristics.
These comparable companies consisted of:



<TABLE>
    <S>      <C>
    (i)      IDT Corporation;
    (ii)     Pacific Gateway Exchange, Inc.;
    (iii)    PRIMUS Telecommunications Group, Incorporated;
    (iv)     RSL Communications, Ltd.; and
    (v)      Startec Global Communications Corporation.
</TABLE>



     In examining these comparable companies, Donaldson, Lufkin & Jenrette
calculated the enterprise value of each company as a multiple of its respective:
(i) last quarter annualized revenue; (ii) projected calendar year 2000 revenue;
(iii) gross property, plant and equipment and (iv) net property plant and
equipment. The enterprise value of a company is equal to the value of its
fully-diluted common equity plus debt and the liquidation value of outstanding
preferred stock, if any, minus cash and the value of certain other assets,
including minority interests in other entities. All historical data was derived
from publicly available sources as of February 9, 2000 and all projected data
was obtained from Wall Street research reports.



     Donaldson, Lufkin & Jenrette performed this analysis in order to compare
the ratio of STAR's enterprise value to its last quarter annualized revenues,
estimated 2000 revenues as provided by World Access, gross property, plant and
equipment and net property, plant and equipment to those of the comparable
companies and to the reference range, which represents a tighter range of the
ratios as deemed reasonable by Donaldson, Lufkin & Jenrette. In addition,
Donaldson, Lufkin & Jenrette compared the enterprise value of STAR to the
implied enterprise values obtained by the above mentioned ratios of the
comparable companies and the reference range and STAR's last quarter annualized
revenues, estimated 2000 revenues as provided by World Access, gross property,
plant and equipment and net property, plant and equipment. Donaldson, Lufkin &
Jenrette's analysis of the comparable companies yielded the following multiple
ranges and implied enterprise values:

     The comparable company analysis showed that the implied multiples of World
Access' consideration were either within or lower than the range of multiples
implied by the prevailing market prices of the comparable companies. In
addition, the analysis showed that the enterprise value based on World Access'
consideration was either within or lower than the range of enterprise values
implied by the multiples of the comparable companies and STAR's last quarter
annualized revenues, estimated 2000 revenues, gross property, plant and
equipment and net property, plant and equipment.

3. ANALYSIS OF SELECTED MERGER AND ACQUISITION TRANSACTIONS



     Donaldson, Lufkin & Jenrette reviewed selected mergers and acquisitions
transactions of companies that operate businesses reasonably similar to that of
STAR. In addition, for purposes of this analysis, Donaldson, Lufkin & Jenrette
selected key mergers and acquisitions transactions deemed most relevant by
Donaldson, Lufkin & Jenrette based on the business characteristics of the
acquiror and/or target and the business nature of the transaction. The following
mergers and acquisitions transactions were deemed most relevant by Donaldson,
Lufkin & Jenrette:


     - Viatel, Inc.'s acquisition of Destia Communications, Inc.


     - PRIMUS Telecommunications Group, Incorporated's acquisition of TresCom
       International, Inc.



     In examining these acquisitions, Donaldson, Lufkin & Jenrette calculated
the enterprise value of the acquired company implied by each of these
transactions as a multiple of the last twelve-month revenue, last quarter
annualized revenue, and net property, plant and equipment. The last twelve-month
period for which financial data for the company at issue has been reported is
referred to as the last twelve-month revenue. In addition, Donaldson, Lufkin &
Jenrette calculated the enterprise values implied by the above mentioned ratios
of the selected mergers and acquisitions transactions and STAR's last
twelve-month revenue, last quarter annualized revenue and net property, plant
and equipment. Donaldson, Lufkin & Jenrette's analysis of these comparable
acquisitions yielded the following multiple ranges and implied enterprise
values:

     The analysis of selected mergers and acquisitions transactions showed that
the implied multiples of World Access' consideration were, in each case, within
or lower than the range of multiples paid by the selected mergers and
acquisitions transactions as well as by the key mergers and acquisitions
transactions. In addition, the analysis of selected mergers and acquisitions
transactions showed that the transaction value of World Access' consideration
was, in each case, within or lower than the range of implied transaction values
based on the multiples paid by selected mergers and acquisition transactions.


4. DISCOUNTED CASH FLOW ANALYSIS


     In addition, Donaldson, Lufkin & Jenrette performed a discounted cash flow
analysis for STAR on a stand-alone basis. The analysis was based upon financial
projections, including synergies, for the five-year period ending fiscal 2004 as
provided by the management of World Access. Donaldson, Lufkin & Jenrette
performed this analysis to estimate the net present value of STAR's enterprise
value and to compare it to the implied enterprise value based on World Access'
consideration. Donaldson, Lufkin & Jenrette calculated EBITDA for STAR. EBITDA
is earnings before interest, taxes, depreciation and amortization and other
items. Donaldson, Lufkin & Jenrette calculated the terminal value of STAR at the
end of the forecast period, by applying a range of estimated EBITDA multiples
selected in Donaldson, Lufkin & Jenrette's subjective judgment. The terminal
value estimates are a hypothetical approximation of the value of the
enterprise's cash flows beyond the end of the five-year period covered by the
management's projections. The management's projected EBITDA and Donaldson,
Lufkin & Jenrette's subjective estimate


                                       51

of the terminal values based on management's projected EBITDA were then
discounted to the present using a range of discount rates selected in Donaldson,
Lufkin & Jenrette's subjective judgment.

     The above analysis shows that the implied enterprise value based on World
Access' consideration of $619.7 million is near the high range of the implied
enterprise values of $507.6 million to $662.4 million obtained by the analysis.



     The summary set forth above does not purport to be a complete description
of the analyses performed by Donaldson, Lufkin & Jenrette but describes the
material elements of the presentation that Donaldson, Lufkin & Jenrette made to
the World Access board on February 11, 2000 in connection with the preparation
of Donaldson, Lufkin & Jenrette's fairness opinion. The preparation of a
fairness opinion involves various determinations as to the most appropriate and
relevant methods of financial analysis and the application of these methods to
the particular circumstances and, therefore, such an opinion is not readily
susceptible to summary description. Donaldson, Lufkin & Jenrette conducted each
of the analyses in order to provide a different perspective on the transaction
and to add to the total mix of information available. Donaldson, Lufkin &
Jenrette did not for a conclusion as to whether any individual analysis,
considered in isolation, supported or failed to support an opinion as to
fairness from a financial point of view. Rather, in reaching its conclusion,
Donaldson, Lufkin & Jenrette considered the results of the analyses in light of
each other and ultimately reached its opinion based on the results of all
analyses taken as a whole. Donaldson, Lufkin & Jenrette did not place any
particular reliance or weight on any individual analysis, but instead concluded
that its analyses, taken as a whole, supported its determination. Accordingly,
notwithstanding the separate factors summarized above, Donaldson, Lufkin &
Jenrette has indicated to World Access that it believes that its analyses must
be considered as a whole and that selecting portions of its analyses and the
factors considered by it, without considering all analyses and factors, could
create an incomplete view of the evaluation process underlying its opinion. The
analyses Donaldson, Lufkin & Jenrette performed are not necessarily indicative
of actual values or future results, which may be significantly more or less
favorable than suggested by these analyses.



ENGAGEMENT LETTER



     Under the terms of an engagement letter dated January 12, 2000, World
Access agreed to pay Donaldson, Lufkin & Jenrette a fee of $400,000 at the time
that Donaldson, Lufkin & Jenrette delivered to the World Access board of
directors its opinion, irrespective of the conclusion reached in the opinion,
and to pay Donaldson, Lufkin & Jenrette a fee of $750,000, less any amounts paid
pursuant to delivery of the fairness opinion, payable in cash promptly upon
consummation of a business combination between World Access and STAR. In
addition, World Access agreed to reimburse Donaldson, Lufkin & Jenrette for all
of its out-of-pocket expenses, including the reasonable fees and expenses of
counsel incurred by Donaldson, Lufkin & Jenrette in connection with its
engagement, and to indemnify Donaldson, Lufkin & Jenrette for liabilities and
expenses arising out of Donaldson, Lufkin & Jenrette's engagement, including
liabilities under federal securities laws.



     The terms of the fee arrangement with Donaldson, Lufkin & Jenrette, which
Donaldson, Lufkin & Jenrette and World Access believe are customary in
transactions of this nature, were negotiated at arms-length between World Access
and Donaldson, Lufkin & Jenrette. World Access' board of directors was aware of
such arrangement, including the fact that a significant portion of the aggregate
fee payable to Donaldson, Lufkin & Jenrette is contingent upon consummation of
the STAR merger.

OPINION OF STAR'S FINANCIAL ADVISOR REGARDING THE STAR MERGER


     Deutsche Bank Securities Inc. acted as financial advisor to the board of
directors of STAR in connection with the proposed merger of World Access and
STAR. At the February 7, 2000, meeting of the board of directors of STAR,
Deutsche Bank delivered its oral opinion, subsequently confirmed in writing
dated as of the same date, to the board of directors of STAR to the effect that,
as of the date of such opinion, based upon and subject to the assumptions made,
matters considered and limits of the review undertaken by Deutsche Bank, the
merger consideration was fair, from a financial point of view, to STAR
stockholders. The full text of Deutsche Bank's opinion is attached as Annex E to
this joint proxy statement/prospectus.



     In connection with Deutsche Bank's role as financial advisor to the board
of directors of STAR, and in arriving at its opinion, Deutsche Bank has, among
other things:


     - reviewed certain publicly available financial information and other
       information concerning STAR and World Access;

     - reviewed certain internal analyses and other information furnished to it
       by STAR and World Access;

     - held discussions with the members of the senior managements of STAR and
       World Access regarding the businesses and prospects of their respective
       companies and the joint prospects of the World Access/STAR combined
       company;

     - reviewed the reported prices and trading activity for the common stock of
       both STAR and World Access;

     - compared certain financial and certain stock market information for STAR
       and World Access with similar information for selected companies whose
       securities are publicly traded;

     - reviewed the terms of the draft STAR merger agreement, dated February 6,
       2000, and assumed that the final form of the STAR merger agreement would
       not vary in any respect that would be material to Deutsche Bank's
       analysis; and

     - performed such other studies and analyses and considered such other
       factors as it deemed appropriate.


     Deutsche Bank prepared its financial analyses of the STAR merger before the
merger agreement with WorldxChange was announced, the PT-1 asset sale agreement
was signed, or the STAR merger agreement was amended on June 7, 2000 to reduce
the exchange ratio from 0.3905 to 0.386595. Deutsche Bank did not consider the
WorldxChange merger, the terms of the PT-1 asset sale agreement, or the June 7,
2000 adjustment in the exchange ratio when analyzing the fairness, from a
financial point of view, of the STAR merger consideration to STAR stockholders.


     In preparing its opinion, Deutsche Bank did not assume responsibility for
the independent verification of, and did not independently verify, any
information, whether publicly available or furnished to it, concerning STAR or
World Access, including, without limitation, any financial information,
forecasts or projections, considered in connection with the rendering of its
opinion. Accordingly, for purposes of its

                                       53
<PAGE>   67

opinion, Deutsche Bank assumed and relied upon the accuracy and completeness of
all such information. Deutsche Bank did not conduct a physical inspection of any
of the properties or assets, and did not prepare or obtain any independent
evaluation or appraisal of any of the assets or liabilities of STAR or World
Access. With respect to the financial forecasts and projections, including
analyses and forecasts made available to Deutsche Bank and used in its analysis,
including analyses and forecasts of certain cost savings, operating
efficiencies, revenue effects and financial synergies expected by STAR and World
Access to be achieved as a result of the STAR merger, Deutsche Bank assumed that
they have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the management of STAR and World Access, as
the case may be, as to the matters covered thereby. In rendering its opinion,
Deutsche Bank expressed no view as to the reasonableness of such forecasts and
projections, or the assumptions on which they are based. Deutsche Bank's opinion
was necessarily based upon economic, market and other conditions as in effect
on, and the information made available to Deutsche Bank as of, the date of its
opinion.

     For purposes of rendering its opinion, Deutsche Bank assumed that, in all
respects material to its analysis:

     - the representations and warranties of STAR and World Access contained in
       the STAR merger agreement are true and correct;

     - STAR and World Access will each perform all of the covenants and
       agreements to be performed by it under the STAR merger agreement;

     - all conditions to the obligations of each of STAR and World Access to
       consummate the STAR merger will be satisfied without any waiver thereof;

     - all material governmental, regulatory or other approvals and consents
       required in connection with the consummation of the transactions
       contemplated by the STAR merger agreement will be obtained; and

     - in connection with obtaining any necessary governmental, regulatory or
       other approvals and consents, or any amendments, modifications or waivers
       to any agreements, instruments or orders to which either STAR or World
       Access is a party or is subject or by which it is bound, no limitations,
       restrictions or conditions will be imposed or amendments, modifications
       or waivers made that would have a material adverse effect on STAR or
       World Access or materially reduce the contemplated benefits of the STAR
       merger to STAR or its stockholders.

     In addition, Deutsche Bank was advised by STAR, and accordingly assumed for
purposes of its opinion, that the STAR merger will be treated as a tax-free
reorganization for federal income tax purposes.

     In connection with Deutsche Bank's role as financial advisor to STAR and in
arriving at its opinion, Deutsche Bank was not requested or authorized to
solicit, and did not solicit, any alternative transactions to the STAR merger.


     The following is a summary of the material financial analyses used by
Deutsche Bank in reaching its opinion and does not purport to be a complete
description of the analyses performed by Deutsche Bank. The following
quantitative information, to the extent it is based on market data, is based on
market data as it existed at or about February 4, 2000, and is not necessarily
indicative of current market conditions. Readers should understand that the
order of analyses described below do not represent relative importance or weight
given to these analyses by Deutsche Bank.



     Analysis of selected publicly traded companies.  Deutsche Bank compared
certain financial information and commonly used valuation measurements for STAR
and World Access to corresponding information and measurements for three groups
of publicly traded telecom services companies: a group of large capitalization
competitive global carriers consisting of Global Telesystems, Energis and
Teleglobe; a group of mid capitalization competitive global carriers consisting
of Primus, RSL and Viatel; and a group of international long distance carriers
consisting of IDT, Pacific Gateway, Startec Global and Telscape International.

                                       54
<PAGE>   68


     The financial information and valuation measurements of the selected
comparable companies included, among other things:



     - total enterprise value, or total enterprise value, which is common equity
       market value plus debt and cash;



     - ratios of total enterprise value to sales for the last reported quarter,
       which was the third quarter of 1999, annualized;



     - ratios of total enterprise value to estimated sales for the year 2000;



     - ratios of total enterprise value to earnings before interest expenses,
       tax, depreciation and amortization, or EBITDA, for the last quarter
       annualized;



     - ratios of total enterprise value to property, plant and equipment, or
       property, plant and equipment, net of depreciation; and



     - ratios of total enterprise value to gross property, plant and equipment.



     The total enterprise value of a company is equal to the value of its
fully-diluted common equity plus debt, cash and the liquidation value of
outstanding preferred stock, if any. Last quarter, annualized revenue means the
last quarter annualized for which financial data for the company at issue has
been reported. In this case, the last quarter was the third quarter of 1999.



     To calculate the total enterprise value multiples for STAR, World Access
and the selected comparable companies, Deutsche Bank used publicly available
information concerning historical and projected financial performance, including
published historical financial information and estimates of future financial
results from published equity research analyst reports.



     For each of the selected comparable companies, Deutsche Bank calculated
five trading multiples: total enterprise value to sales of the last quarter
annualized and for 2000 estimated; total enterprise value to EBITDA of last
quarter annualized; and total enterprise value to property, plant and equipment
net of depreciation and to gross property, plant and equipment. This analysis
indicated the following medians and means:

(1) The range, median and mean of the EBITDA multiple for the Big Cap
    Competitive Global Carrier group were based solely on the EBITDA multiple
    for Teleglobe because the EBITDA multiple was not meaningful for each of
    Global Telesystems and Energis.

(2) The range, median and mean of the gross property, plant and equipment
    multiple were based solely on the gross property, plant and equipment
    multiple of Global Telesystems because the gross property, plant and
    equipment multiple for each of Energis and Teleglobe was not applicable.

(3) The range, median and mean of the 2000E sales multiple for the International
    Long Distance Carrier group was calculated excluding Telscape International
    because the 2000E sales multiple for Telscape International was not
    available.
(4) The range, median and mean of the EBITDA multiple for the International Long
    Distance Carrier group was calculated excluding Startec Global and Telscape
    International because the EBITDA multiple for each of these companies was
    not meaningful.


     Deutsche Bank calculated (i) the implied total enterprise value of STAR on
a stand alone basis; (ii) the implied equity value of STAR on a stand alone
basis; and (iii) the implied equity value per share of STAR on a stand alone
basis, in each case based on the trading multiples for the International Long
Distance Carrier group. Deutsche Bank analyzed the three groups and concluded
that STAR most closely resembles the International Long Distance Carrier group
and, more specifically, IDT and Pacific Gateway in that group. Deutsche Bank
deemed World Access most comparable to a range between the International Long
Distance Carrier group and the Mid Cap Competitive Global Carrier Group with a
closer emphasis on the International Long Distance Carrier Group. The implied
total enterprise value, implied equity value and implied equity value per share
for STAR, in each case based on the multiple ranges for the International Long
Distance Carriers, are as follows:

     Deutsche Bank also calculated (i) the implied total enterprise value of
World Access on a stand alone basis; (ii) the implied equity value of World
Access on a stand alone basis; and (iii) the implied equity value per share of
World Access on a stand alone basis, in each case based on a comparable trading

The gross property, plant and equipment for World Access (pro forma for its
previously announced acquisitions and divestitures) was not provided to Deutsche
Bank and therefore Deutsche Bank did not calculate total enterprise value as a
multiple of the gross property, plant and equipment.



     The preceding analysis allows a comparison of implied per share equity
values, based on multiple ranges of comparable publicly held companies, of STAR
and World Access. The relationship of those implied per share equity values may
be compared with the exchange ratio under the STAR merger agreement.


     None of the companies utilized as a comparison are identical to STAR or
World Access. Accordingly, Deutsche Bank believes the analysis of the publicly
traded comparable companies is not simply mathematical. Rather, it involves
complex considerations and qualitative judgments concerning differences in
financial and operating characteristics of the comparable companies and other
factors that could affect the public trading value of the comparable companies.


     Contribution analysis.  Deutsche Bank analyzed the relative contributions
of STAR and World Access to the estimated pro forma income statement and balance
sheet of the combined company. This analysis showed that on a pro forma combined
basis (excluding (i) the effect of any synergies that may be realized as a
result of the STAR merger, and (ii) non-recurring expenses relating to the STAR
merger), based on the estimated 2000 figures, STAR and World Access would
account for approximately 47.4% and 52.6%, respectively, of the combined
company's pro forma total revenues, approximately 52.3% and 47.7%, respectively,
of the combined company's gross profit and (8.2%) and 108.2%, respectively, of
the combined company's EBITDA. These percentage contributions may be compared
with the percentage of World Access shares to be owned following the STAR merger
(without giving effect to the WorldxChange merger or the June 7, 2000 adjustment
of the exchange ratio) by former STAR stockholders and by the stockholders of
World Access before the STAR merger of 20.6% and 79.4%, respectively, and
approximately 28.9% and 71.1%, respectively, of the combined company's total
enterprise value (based on the closing price of World Access stock on February
4, 2000 and on the assumptions that there will be no increase in the STAR merger
consideration as a result of the sale of PT-1 and that all of the merger
consideration will be paid in stock).



     The contribution analysis shows that the percentage of World Access shares
to be owned by the former STAR holders is substantially higher than STAR's
contribution to the combined companies' EBITDA, but less than STAR's
contribution to the combined companies' revenues and gross profits.


     Discounted cash flow analysis.  Deutsche Bank performed a discounted cash
flow analysis for both World Access and STAR. Deutsche Bank calculated the
discounted cash flow values for each of World Access and STAR as the sum of the
net present values of (i) the estimated future cash flow that World

                                       57
<PAGE>   71


Access or STAR, as the case may be, will generate for the years 2000 through
2004, plus (ii) the value of World Access or STAR at the end of such period. The
total enterprise values, equity values and equity values per share for STAR were
based on the financial projections for STAR for the years 2000 through 2004
prepared by STAR's management. The discounted cash flow analysis of STAR
management's projections assumes ranges of discount rates of 14% to 16% and 2004
estimated EBITDA exit multiples of 9x to 11x. The total enterprise values,
equity values and equity values per share for World Access were based on the
financial projections for World Access for the years 2000 through 2004 prepared
by World Access' management. The discounted cash flow analysis of World Access
management's projections assumes ranges of discount rates of 12% to 14% and 2004
estimated EBITDA exit multiples of 11x to 13x. For the combined company,
Deutsche Bank used the same discounted cash flow methodology as for the
discounted cash flow analyses of STAR and World Access on a stand alone basis
and assumed the same ranges of discount rates and 2004 estimated exit multiples
as World Access on a stand alone basis. Projections for the combined company
included assumed synergies and transaction expenses. This analysis indicated:

Access shown in the foregoing analysis may be compared with the exchange ratio

     Pro forma financial effects analysis.  Deutsche Bank analyzed certain pro
forma effects of the STAR merger. Based on such analysis, Deutsche Bank computed
the share price, revenues per share and total debt per share for STAR
stockholders pre-transaction, for stockholders of the combined company and the
STAR equivalent post-transaction, based on management's 2000 estimates, after
taking into account the potential cost savings and other synergies identified by
management that STAR and World Access could achieve if the STAR merger was
consummated and after non-recurring costs relating to the STAR merger, and
assuming the exchange ratio is 0.3905 and also assuming that the entire
consideration is stock. Deutsche Bank calculated the following pro forma effects
of the STAR merger, after taking into account the potential cost savings and
other synergies and after non-recurring costs:

</TABLE>



     This analysis shows that, based on management's 2000 estimates, the
STAR-World Access merger (without giving effect to the WorldxChange merger or
the June 7, 2000 adjustment in the exchange ratio), on a pro forma basis per
STAR share equivalent, would increase EBITDA, EBIT and book value and reduce
debt, but would reduce revenues.


     Premiums analysis.  Deutsche Bank conducted a premiums analysis, comparing
the World Access/STAR transaction to the median and mean of 27 telecom
transactions, completed or pending, greater than $100 million and less than $2
billion for the period of May 1, 1997 to February 4, 2000 and to the median and
mean of 124 general transactions, completed or pending, greater than $250
million and less than $1 billion that resulted in a controlling stake for the
period of January 1, 1999 to February 4, 2000. The premiums analysis was
conducted one day prior to announcement date, one week prior to announcement

                                       58

date and four weeks prior to announcement date. The premium to STAR's share
price was calculated using the original announcement date of the execution of
the letter of intent of December 20, 1999, to enter into the STAR merger and an
exchange ratio of 0.3905 World Access share per STAR share. This analysis

     This premium analysis permits a comparison between the premium over STAR's

     Other considerations and analyses.  In connection with its opinion Deutsche
Bank also considered, among other things:



     - telecom equipment company trading and transaction comparables to
       corroborate World Access' statement that it will be able to sell its
       Equipment Division for $525 to $600 million,



     - historical exchange ratios of World Access and STAR based on historical
       trading prices,



     - the amounts of STAR shares that have traded at different price levels,
       and



     - precedent telecom services transactions.


     Because many of the precedent transactions occurred in market conditions
for international long distance companies that differed from market conditions
at the time the financial analyses were conducted and/or because business mix or
other factors made the targets in the precedent transactions non-comparable to
STAR, while Deutsche Bank reviewed precedent telecom services transactions, it
did not rely on a precedent transactions analysis.


     The foregoing summary describes analyses that Deutsche Bank deemed material
in its presentation to the STAR board of directors, but it is not a
comprehensive description of all analyses performed by Deutsche Bank in
connection with preparing its opinion. The preparation of a fairness opinion is
a complex process involving the application of subjective business judgment in
determining the most appropriate and relevant methods of financial analysis and
the application of those methods to the particular circumstances and, therefore,
is not readily susceptible to summary description. Deutsche Bank believes that
its analyses must be considered as a whole and that considering any portion of
such analyses and of the factors considered without considering all analyses and
factors could create a misleading view of the process underlying the opinion. In
arriving at its fairness determination, Deutsche Bank did not assign specific
weights to any particular analyses.


     In conducting its analyses and arriving at its opinions, Deutsche Bank
utilized a variety of generally accepted valuation methods. The analyses were
prepared solely for the purpose of enabling Deutsche Bank to provide its opinion
to the board of directors of STAR as to the fairness to STAR stockholders, from
a financial point of view, of the merger consideration and do not purport to be
appraisals or necessarily reflect the prices at which businesses or securities
actually may be sold, which are inherently subject to uncertainty. In connection
with its analyses, Deutsche Bank made, and was provided by STAR's management
with, numerous assumptions with respect to industry performance, general
business and economic conditions and other matters, many of which are beyond
STAR's or World Access' control. Analyses based on estimates or forecasts of
future results are not necessarily indicative of actual past or

                                       59
<PAGE>   73

future values or results, which may be significantly more or less favorable than
suggested by such analyses. Because such analyses are inherently subject to
uncertainty, being based upon numerous factors or events beyond the control of
STAR, World Access or their respective advisors, neither STAR nor Deutsche Bank
nor any other person assumes responsibility if future results or actual values
are materially different from these forecasts or assumptions.


     The terms of the STAR merger were determined through negotiations between
STAR and World Access and were approved by the STAR board of directors. Although
Deutsche Bank provided advice to the STAR board of directors as to the fairness
of the merger consideration to the stockholders of STAR, from a financial point
of view, the decision to enter into the STAR merger was solely that of the STAR
board of directors. The opinion of Deutsche Bank was only one of a number of
factors taken into consideration by the STAR board of directors in making its
determination to approve the STAR merger. Deutsche Bank's opinion was provided
to the STAR board of directors to assist it in connection with its consideration
of the STAR merger and does not constitute a recommendation to any holder of
STAR common stock as to how to vote with respect to the STAR merger.


     The STAR board of directors selected Deutsche Bank as financial advisor in
connection with the STAR merger based on Deutsche Bank's qualifications,
expertise, reputation and experience in mergers and acquisitions. STAR has
retained Deutsche Bank pursuant to an engagement letter dated January 25, 2000.
As compensation for Deutsche Bank's services in connection with the STAR merger,
a cash fee of $250,000 became payable by STAR to Deutsche Bank upon signing and
STAR will pay Deutsche Bank an additional $1,050,000 upon consummation of the
STAR merger. Regardless of whether the STAR merger is consummated, STAR has
agreed to reimburse Deutsche Bank for reasonable fees and disbursements of
Deutsche Bank's counsel and all of Deutsche Bank's reasonable travel and other
out-of-pocket expenses incurred in connection with the STAR merger or otherwise
arising out of the retention of Deutsche Bank under the engagement letter. STAR
has also agreed to indemnify Deutsche Bank and certain related persons to the
full extent lawful against certain liabilities, including certain liabilities
under the federal securities laws that may arise out of its engagement or the
STAR merger.

     Deutsche Bank is an internationally recognized investment banking firm
experienced in providing advice in connection with mergers and acquisitions and
related transactions. It is an affiliate of Deutsche Bank AG (together with its
affiliates, the DB Group).

     One or more members of the DB Group have, from time to time, provided
investment banking, commercial banking, including extension of credit, other
financial services to STAR and World Access or their respective affiliates for
which it has received compensation. In the ordinary course of business, members
of the DB Group may actively trade in the securities and other instruments and
obligations of STAR and World Access for their own accounts and for the accounts
of their customers. Accordingly, the DB Group may at any time hold a long or
short position in such securities, instruments and obligations.


CONSIDERATION THAT STAR STOCKHOLDERS WILL RECEIVE IN THE STAR MERGER


     Upon completion of the STAR merger, each outstanding share of STAR common
stock will be automatically canceled and converted into the right to receive one
of two forms of merger consideration to be determined by World Access.


     - Under the first form of consideration, each STAR stockholder will be
       entitled to receive, for each share of STAR common stock, 0.386595 shares
       of World Access common stock, subject to upward adjustment if STAR sells
       PT-1 prior to the completion of the STAR merger for net cash proceeds in
       excess of $150.0 million.



     - Under the second form of merger consideration, each STAR stockholder will
       be entitled to receive, for each share of STAR common stock, the same
       total value as that paid in the first form of consideration. However,
       under the second form, each STAR stockholder will receive up to 60% of
       its consideration in World Access common stock and up to 40% of its
       consideration in cash. If


                                       60
<PAGE>   74


       World Access selects the second form of consideration, each STAR
       stockholder will receive the same percentages of stock and cash as other
       STAR stockholders.



     No fractional shares of World Access common stock will be issued in
connection with the STAR merger. Instead, STAR shareholders will receive cash,
without interest, instead of a fractional share of World Access common stock.


     Shares of STAR common stock for which dissenters' rights of appraisal, if
available, have been perfected in accordance with Delaware law will not be
entitled to receive the merger consideration described above.


     Upon completion of the STAR merger, each outstanding STAR stock option or
warrant will be automatically converted into an option to purchase such number
of shares of World Access common stock as is equal to the number of shares of
STAR common stock covered under such STAR stock option or warrant multiplied by
the exchange ratio at a per share price equal to the exercise price specified in
the STAR stock option or warrant divided by the exchange ratio. The amount of
World Access common stock each STAR stock option or warrant will be convertible
into is subject to upward adjustment if STAR sells PT-1 before the completion of
the STAR merger for net cash proceeds in excess of $150.0 million. Each newly
issued World Access stock option will contain terms which are substantially
similar to the terms governing the original STAR stock option or warrant.



COMPLETION OF THE STAR MERGER



     The completion of the STAR merger will occur two business days after the
conditions to completion are satisfied or waived or at a later time agreed to by
World Access and STAR. The STAR merger will be effective at the time that the
certificate of merger is filed unless World Access and STAR specify a later
effective time in the certificate of merger.



MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE STAR MERGER



     The following discussion summarizes the material federal income tax
consequences of the STAR merger. Long Aldridge & Norman LLP, as counsel to World
Access, is of the opinion that the following discussion sets forth the material
federal income tax consequences of the STAR merger under the federal income tax
laws in effect as of the date of this joint proxy statement/prospectus. The
following discussion is not a complete analysis of all aspects of federal income
taxation that may be relevant to you as a STAR stockholder in light of your
particular circumstances. For example, it does not address the federal income
tax considerations or the special tax rules that may be relevant to you if you
are one of the following types of holders:



     - an insurance company;



     - a tax-exempt organization;



     - an employee stock ownership plan;



     - a bank;



     - a broker, dealer or financial institution;



     - a holder that holds STAR common stock as part of a position in a
       "straddle" or as part of a "hedging" or "conversion" transaction for
       federal income tax purposes;



     - a holder that has a "functional currency" other than the United States
       dollar;



     - a holder subject to the alternative minimum tax;



     - a holder that is not a citizen or resident of the United States, or that
       is a foreign corporation, foreign partnership or foreign estate or trust
       as to the United States;


                                       61
<PAGE>   75


     - a holder who acquired shares of STAR common stock pursuant to the
       exercise of options or otherwise as compensation or through a
       tax-qualified retirement plan; or



     - a holder of options to acquire shares of STAR common stock.



     In addition, the discussion does not consider the effect of any foreign,
state, local, or other tax laws, or any tax consequences, such as estate or gift
tax, other than the federal income tax consequences of the STAR merger that may
be applicable to STAR stockholders, or the consequences of transactions
completed before or after the STAR merger. Further, this discussion assumes that
as a STAR stockholder, you hold your STAR common stock as a "capital asset"
within the meaning of Section 1221 of the Internal Revenue Code of 1986, as
amended. Generally, a capital asset is property held for investment. This
discussion is based on the Internal Revenue Code and final, temporary and
proposed treasury regulations promulgated under the Internal Revenue Code,
administrative pronouncements and rulings, and judicial decisions as of the date
of this joint proxy statement/prospectus, all of which are subject to change or
differing interpretations at any time with possible retroactive effect and any
such change could affect the continuity and validity of this discussion.



     We have not requested a ruling from the Internal Revenue Service with
respect to the federal income tax consequences of the STAR merger nor is the
completion of the STAR merger conditioned on the receipt by World Access or STAR
of such a ruling or an opinion of tax counsel concerning such tax consequences.
YOU ARE URGED TO CONSULT YOUR OWN TAX ADVISOR AS TO THE SPECIFIC FEDERAL, STATE,
LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES TO YOU OF THE STAR MERGER.


  The STAR merger


     Long Aldridge & Norman LLP has rendered an opinion to World Access that the
STAR merger will constitute a "reorganization" within the meaning of Section
368(a) of the Internal Revenue Code. This opinion is subject to the limitations,
qualifications and assumptions referred to herein and in such opinion. In
rendering its opinion as to the status of the STAR merger as a "reorganization,"
and in rendering its opinion with respect to the following discussion, counsel
has relied upon, and has assumed the accuracy of, information, factual
statements and representations made by World Access and STAR in this joint proxy
statement/prospectus and the STAR merger agreement, including those
representations to counsel contained in certificates of their officers. Any
inaccuracy or change with respect to such information, representations or
assumptions, or any past or future actions by World Access or STAR contrary to
such information, representations or assumptions could adversely affect the
conclusions reached in such opinion and the discussion set forth below.



     Counsel's opinion neither binds the Internal Revenue Service nor precludes
it or the courts from adopting a contrary position, and no assurance can be
given that contrary positions will not be successfully asserted by the Internal
Revenue Service or adopted by a court if the issues are litigated.



     The PT-1 asset sale will not prevent "reorganization" treatment.  In order
for the STAR merger to qualify as a "reorganization," STI Merger Co., the
subsidiary of World Access that STAR will merge into in the STAR merger, must
acquire "substantially all" of STAR's assets under the Internal Revenue Code,
notwithstanding the fact that the PT-1 asset sale will occur prior to the STAR
merger and is counted as an asset that STAR should have at the effective time of
the merger for purposes of this calculation. The Internal Revenue Service has
publicly ruled that a target corporation's pre-merger sale of 50% of its
historic business assets for cash did not violate the "substantially all"
requirement where all the remaining assets, including the cash proceeds were
transferred to the acquiring corporation. Based on this Internal Revenue Service
published ruling position on pre-merger asset sales by a target corporation,
STAR's representations that the Internal Revenue Service private letter ruling
requirements regarding the "substantially all" requirement will be met, and the
other Internal Revenue Service and judicial authority, the "substantially all"
requirement will be met in the STAR merger and the PT-1 asset sale will not
prevent the STAR merger from constituting a "reorganization" within the meaning
of Section 368(a) of the Internal Revenue Code.


                                       62
<PAGE>   76


     Under the "continuity of business enterprise requirement," STI Merger Co.
must also continue STAR's "historic business" or use a significant portion of
STAR's historic assets in a business in order for the STAR merger to qualify as
a "reorganization" under the Internal Revenue Code. World Access has represented
to counsel that STI Merger Co. will satisfy this test irrespective of the PT-1
asset sale. Based on such World Access representation, Internal Revenue Service
and judicial authority, the "continuity of business enterprise" requirement will
also be met with respect to the STAR merger.



     The balance of this discussion is based on the conclusion in the opinion
that the STAR merger will constitute a "reorganization" within the meaning of
Section 368(a) of the Internal Revenue Code, and that STAR completes the PT-1
asset sale prior to the STAR merger.


     World Access stockholders will not recognize any gain or loss for federal
income tax purposes solely as a result of the STAR merger.

  Tax considerations for STAR stockholders


     Receipt of World Access stock in the STAR merger.  You will recognize
neither gain nor loss upon the exchange of your STAR common stock for World
Access common stock and fractional share interests. Your tax basis in the shares
of World Access common stock you receive in the exchange will be the same as the
tax basis of the shares of STAR common stock you surrender in the exchange less
any portion of such basis allocable to any fractional share interest in any
share of World Access common stock for which cash is received. The holding
period of the World Access common stock you receive in the exchange will include
the holding period during which you held your STAR common stock, provided you
held such shares as a capital asset as of the effective time of the STAR merger.



     Receipt of World Access stock and cash.  If World Access elects to pay
cash, and you realize gain on the exchange of your STAR common stock for a
combination of cash and World Access common stock and fractional share
interests, you will be required to recognize such gain in an amount equal to the
lesser of (i) the amount of gain you realize on the exchange (i.e., the excess
of the sum of the cash and the fair market value of the World Access common
stock you receive over your tax basis in the STAR common stock surrendered in
the exchange) and (ii) the amount of cash you receive in the exchange. If,
however, you realize a loss on the exchange of your STAR common stock for a
combination of cash and World Access common stock, you cannot recognize such
loss.



     Your tax basis in the shares of World Access common stock you receive in
the exchange in which you also receive cash will be the same as the tax basis of
your shares of STAR common stock surrendered in the exchange, less any portion
of such basis allocable to any fractional share interest in any share of World
Access common stock for which cash is received, increased by the amount of any
gain recognized in the exchange, whether treated as a capital gain or a dividend
as discussed below, and decreased by the amount of cash you receive. The holding
period of the World Access common stock you receive in the exchange will include
the holding period during which you held your STAR common stock.



     Character of gain recognized.  The character of the gain you are required
to recognize upon your receipt of cash depends on your particular facts and
circumstances as a STAR stockholder. Assuming you held your STAR common stock as
a capital asset, any gain recognized will be characterized as capital gain
unless your receipt of such cash is treated as having the effect of the
distribution of a dividend under the Internal Revenue Code.



     To determine whether any such recognized gain is capital gain or is a
dividend, a hypothetical redemption is deemed to occur under which a STAR
stockholder that receives a combination of cash and World Access common stock is
treated as (i) hypothetically receiving solely shares of World Access common
stock in exchange for all of its STAR common stock, and (ii) having a portion of
its shares of World Access common stock equal in value to the cash actually
received in the STAR merger redeemed by World Access. The cash you receive in
the hypothetical redemption will have the effect of a distribution of a dividend
to you unless such hypothetical redemption (i) is "not essentially equivalent to
a dividend" with respect to you or (ii) results in a "substantially
disproportionate" redemption of your equity


                                       63
<PAGE>   77


interest in World Access, in both cases after giving effect to the constructive
ownership rules of the Internal Revenue Code. If either of these redemption
tests is satisfied, then your gain will be capital gain, and will be long-term
capital gain if your STAR common stock was held for more than one year as of the
effective time of the STAR merger. These redemption tests and the application of
the constructive ownership rules are complex. Your tax consequences will depend
upon your particular facts and circumstances as a STAR stockholder. We urge you
to consult with your tax advisor with respect to these matters.



     If none of the redemption tests is satisfied, you will be treated as having
received a dividend distribution in that hypothetical redemption exchange. The
amount of such distribution will generally equal the amount of cash you receive,
but not in excess of the gain you realize on the exchange pursuant to the STAR
merger, and such amount will be treated as a dividend, and thus ordinary income,
to the extent of your allocable portion of the accumulated earnings and profits,
if any, as determined for federal income tax purposes of STAR. If the amount of
such distribution exceeds your allocable portion of STAR's accumulated earnings
and profits, then the excess will first be applied against and reduce your basis
in such stock, but not below zero, and then any excess will be treated as gain
from the sale or exchange of World Access common stock, and thus capital gain,
and will be long-term capital gain if your STAR common stock was held for more
than one year as of the effective time of the STAR merger. If such distribution
is taxable as a dividend to you as a corporate stockholder, it may qualify for
the "dividends received deduction;" such dividend distribution may, however,
also be subject to the "extraordinary dividend" provisions of the Internal
Revenue Code.



     Cash for fractional shares.  Based on the current published ruling position
of the Internal Revenue Service, you will recognize gain or loss measured by the
difference between the amount of cash received and the portion of the tax basis
of your STAR common stock allocable to such fractional share interest. Such gain
or loss will be capital gain or loss, and will be long-term capital gain if your
STAR common stock was held for more than one year as of the effective time of
the STAR merger.



     Cash received by dissenting STAR stockholders.  If you exercise appraisal
rights, any cash received in connection therewith will be treated as having been
received in redemption of your STAR common stock, provided the payment is not
treated as a dividend pursuant to the Internal Revenue Code. If, after such
redemption, you own no World Access stock after giving effect to the
constructive ownership rules of the Internal Revenue Code, then you will
recognize gain or loss measured by the difference between the amount of cash
received and the tax basis of your STAR common stock surrendered, which will be
long-term capital gain or loss if your STAR common stock was held for more than
one year as of the effective time of the STAR merger.



     Reporting requirements.  When you file your federal income tax return for
the taxable year in which the STAR merger occurs, you will be required to attach
a statement to your return which includes certain information required by the
Internal Revenue Service concerning your participation as a STAR stockholder in
the STAR merger. ACCORDINGLY, YOU ARE URGED TO CONSULT WITH YOUR TAX ADVISOR
CONCERNING COMPLIANCE WITH THIS REQUIREMENT AND ANY OTHER TAX REPORTING
REQUIREMENTS.


  Tax considerations for the corporate parties


     World Access, STI Merger Co. and STAR.  No gain or loss will be recognized
by World Access, STI Merger Co. or STAR as a result of the STAR merger.



     Limitation on STAR tax attributes.  Under the Internal Revenue Code, STI
Merger Co. will succeed to the net operating losses, certain "recognized
built-in losses," capital losses, general business credits, minimum tax credits,
excess foreign tax credits and certain other tax attributes of STAR. Use of
these tax attributes by World Access is subject to specific limitations under
the Internal Revenue Code and certain provisions of the treasury regulations
governing the filing of a consolidated federal income tax return, such as the
"separate return limitation year" rules. After an ownership change, the amount
of the loss corporation's taxable income for a post-ownership change year that
may be offset by the loss corporation's net operating losses arising before the
ownership change is annually limited to an amount referred to as the

                                       64
<PAGE>   78


"Section 382 limitation." The Section 382 limitation generally equals the
product of (i) the fair market value of the loss corporation's stock immediately
before the ownership change, multiplied by (ii) the federal long-term,
tax-exempt rate published monthly by the Internal Revenue Service, which was
5.53% for August 2000.



     STAR and its domestic subsidiaries are members of a "consolidated group"
which files a consolidated federal income tax return. The STAR consolidated
group, with STI Merger Co. as STAR's corporate successor, will constitute a
"loss subgroup" which will undergo a Section 382 ownership change upon
completion of the STAR merger. Utilization of any STAR loss subgroup's net
operating loss carryover, after taking into account the PT-1 sale, which we
refer to as the "pre-change STAR loss subgroup net operating losses," against
future World Access consolidated federal taxable income will be subject to an
annual loss subgroup Section 382 limitation.



     An additional limitation may apply under which the pre-change STAR loss
subgroup net operating losses can only be used to the extent of the "qualifying
separate return limitation year subgroup" members' aggregate, cumulative
contribution to World Access consolidated taxable income, or the "separate
return limitation year limitation." Because the STAR loss subgroup and its
separate return limitation year net operating loss subgroup should be treated as
co-extensive, and the Section 382 ownership change and separate return
limitation year event will occur at the same time, the separate return
limitation year limitation should be eliminated with respect to the STAR loss
subgroup net operating losses. Notwithstanding the foregoing, it is anticipated
that any net operating loss carryovers of STAR will be used to partially offset
gain to be recognized by STAR from the sale of the PT-1 assets.



     Limitation on World Access tax attributes.  World Access and its domestic
subsidiaries are members of a "consolidated group" which files a consolidated
federal income tax return. For its taxable year ended December 31, 1999, the
World Access consolidated group incurred a consolidated net operating loss, and
has a consolidated net operating loss carryover. As such, it constitutes a "loss
group." World Access believes that the World Access loss group may have already
incurred a Section 382 ownership change in either or both of its 1998 and 1999
taxable years. Thus, the World Access consolidated group's ability to utilize
its own consolidated net operating loss carryover as of December 31, 1999
against its future consolidated federal taxable income may already be subject to
an annual loss group Section 382 limitation.



     If consummation of either or both the STAR merger and the WorldxChange
merger does result in an ownership change for the World Access loss group, the
amount of such annual loss group Section 382 limitation will depend in part, on
future values which cannot be predicted at this time. In the case of successive
ownership changes, the applicable pre-ownership change World Access loss group
or member's net operating losses will be subject to the lowest amount of Section
382 limitation which results from any of such successive ownership changes. If
instead, completion of either or both the STAR merger and the WorldxChange
merger does not result in an ownership change for the World Access loss group,
then any existing annual loss group Section 382 limitation for World Access will
simply continue to apply.


EXCHANGE OF STAR STOCK CERTIFICATES FOR WORLD ACCESS STOCK CERTIFICATES


     When the STAR merger is completed, World Access' exchange agent will mail a
letter of transmittal and instructions to former STAR stockholders describing
the procedures for surrendering STAR stock certificates in exchange for the
applicable STAR merger consideration. STAR stockholders will be required to
deliver their STAR stock certificates, an executed letter of transmittal and any
other required documents to the exchange agent. The STAR stock certificates will
be canceled, and STAR stockholders will receive the number of shares of World
Access common stock and a check for any cash consideration to which they are
entitled under the STAR merger agreement. STAR stockholders also will receive
cash instead of fractional shares of World Access common stock that they would
have otherwise received.



     YOU SHOULD NOT SUBMIT YOUR STAR STOCK CERTIFICATES FOR EXCHANGE UNLESS AND
UNTIL YOU RECEIVE THE TRANSMITTAL INSTRUCTIONS AND A FORM OF LETTER OF
TRANSMITTAL FROM THE EXCHANGE AGENT.


                                       65
<PAGE>   79

RESTRICTIONS ON SALES OF SHARES BY AFFILIATES OF WORLD ACCESS AND STAR


     The World Access common stock that will be issued in the STAR merger will
be registered under the Securities Act. These shares will be freely transferable
under the Securities Act, except for shares issued to any person who is an
affiliate of either World Access or STAR. Affiliates include individuals or
entities that control, are controlled by, or are under common control of, either
World Access or STAR and may include some of their respective officers,
directors and principal stockholders. Affiliates may not sell the shares of
World Access common stock they acquire in the STAR merger except pursuant to:



     - an effective registration statement under the Securities Act covering the
       resale of those shares;



     - Rule 145 under the Securities Act; or



     - any other exemption under the Securities Act.


ACCOUNTING TREATMENT OF THE STAR MERGER


     World Access intends to account for the STAR merger as a purchase for
financial reporting and accounting purposes, under United States generally
accepted accounting principles. After the STAR merger, the results of operations
of World Access and STAR will be included in the consolidated financial
statements of World Access. The purchase price will be allocated based on the
fair values of the assets acquired and the liabilities assumed. Any excess of
cost over fair value of the net tangible assets of STAR acquired will be
recorded as goodwill and other intangible assets and will be amortized by
charges to operations under United States generally accepted accounting
principles. These allocations will be made based upon valuations and other
studies that have not yet been finalized.


REGULATORY FILINGS AND APPROVALS REQUIRED TO COMPLETE THE STAR MERGER


     The STAR merger is subject to the requirements of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended. The Hart-Scott-Rodino Act
prevents the completion of transactions until required information and materials
are furnished to the Antitrust Division of the Department of Justice and the
Federal Trade Commission and the appropriate waiting periods end or expire.
World Access and STAR have filed the required information and materials with the
Antitrust Division of the Department of Justice and the Federal Trade
Commission. The Department of Justice and Federal Trade Commission granted an
early termination of the waiting period, effective March 16, 2000. No further
action under the Hart-Scott-Rodino Act is required, as long as the STAR merger
is completed prior to March 16, 2001.



     The Antitrust Division of the Department of Justice or the Federal Trade
Commission may challenge the STAR merger on antitrust grounds either before or
after expiration of the waiting period. Other persons could take action under
the antitrust laws, including seeking to enjoin the STAR merger. Additionally,
at any time before or after the completion of the STAR merger or the expiration
of the waiting period, any state could take action under the antitrust laws.


     The STAR merger also requires notification in certain European countries.


     Under the German Competition Act, the German Cartel Office must be notified
of the STAR merger, and the STAR merger cannot be completed until it has been
approved by the German Cartel Office or a one month waiting period has expired.
The waiting period starts from the date that the German Cartel Office considers
the notification complete. On May 18, 2000, the German Cartel Office approved
the STAR merger.


     Following the completion of the STAR merger, an information filing must be
made in Denmark with the national competition authority.


     The STAR merger is subject to state and federal telecommunications
regulatory approvals. All but two of the state regulatory agencies and the
Federal Communications Commission require prior notice or approval of the STAR
merger. Requests for approval or notifications of the STAR merger have been
filed on behalf of World Access and STAR in 48 states and with the Federal
Communications Commission.


                                       66
<PAGE>   80


The legal standard for approval varies from state to state, but approval of the
STAR merger generally requires a showing that it is consistent with the public
interest. The Federal Communications Commission has approved the STAR merger.



     STAR and World Access cannot complete the STAR merger unless and until the
registration statement of which this joint proxy statement/prospectus is a part
is declared effective and STAR and World Access are in compliance with Delaware
law.



     Other than as described above, we are not aware of any other material
governmental or regulatory approval required for completion of the STAR merger.



RIGHTS OF DISSENTING STAR STOCKHOLDERS



     If World Access elects to convert shares of STAR common stock into the
right to receive a combination of shares of World Access common stock and cash
in the STAR merger, and you are a STAR stockholder who does not wish to accept
the merger consideration, you have the right to demand the appraisal of and be
paid the fair value of your shares in cash. The fair value of your shares of
STAR common stock will exclude any element of value arising from the expectation
or completion of the STAR merger. Appraisal rights are not available if World
Access elects to convert shares of STAR common stock into the right to receive
shares of World Access common stock only.



     THIS JOINT PROXY STATEMENT PROSPECTUS CONSTITUTES THE NOTICE OF APPRAISAL
RIGHTS REQUIRED BY DELAWARE LAW. FAILURE TO PROPERLY AND TIMELY COMPLY WITH
THESE PROCEDURES WILL RESULT IN THE LOSS OF YOUR APPRAISAL RIGHTS. IF YOU LOSE
YOUR APPRAISAL RIGHTS, YOU WILL RECEIVE THE MERGER CONSIDERATION ONLY. THE
FOLLOWING DISCUSSION IS A SUMMARY OF DELAWARE LAW AND IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE RELEVANT PROVISIONS OF DELAWARE LAW, A COPY OF
WHICH IS ATTACHED AS ANNEX H AND INCORPORATED HEREIN BY REFERENCE.



     If you have a beneficial interest in STAR common stock held of record by
another person or entity, such as a nominee, and you wish to exercise the right
to appraisal, if available, you must promptly act to cause the record holder to
follow the steps below and in Annex H properly and in a timely manner.



     Delaware courts have decided that the statutory appraisal remedy, depending
on factual circumstances, may or may not be a stockholder's exclusive remedy in
connection with transactions such as the STAR merger.



     Written demand.  If World Access elects to convert shares of STAR common
stock into the right to receive both shares of World Access common stock and
cash, and you are a STAR common stockholder who wishes to exercise appraisal
rights you must deliver a written demand for appraisal of your shares of STAR
common stock to STAR before the vote on the STAR merger at the STAR stockholders
meeting. The demand should be delivered to STAR at 223 East De La Guerra Street,
Santa Barbara, California 93101, Attention: Corporate Secretary.



        Your written demand must reasonably inform STAR:



           - of your identity as a STAR common stockholder; and



           - that by your written demand, you intend to demand appraisal of your
             shares.



        An abstention or proxy or vote against the STAR merger is not a written
        demand for appraisal.



        You must hold your shares of STAR common stock of record:



           - on the record date for the STAR stockholders meeting; and



           - from the time you make the written demand, continuously through the
             STAR merger.



        You must not vote in favor of the STAR merger or consent to the STAR
        merger in writing.



     After the STAR merger.  Within 10 days after the STAR merger, if appraisal
rights are available, World Access must send notice of the STAR merger to each
person who has satisfied the procedures

                                       67
<PAGE>   81


established by Delaware law. Within 120 days after the STAR merger, if you are a
STAR common stockholder who complied with these appraisal procedures, you are,
upon written request, entitled to receive from World Access a statement of:



        - the total number of shares of STAR common stock not voted for the STAR
          merger and for which written demands for appraisal were received; and



        - the total number of holders of such shares.



This statement must be mailed by World Access within ten days after its receipt
of the written request for the statement or within ten days after the expiration
of the period for delivery of written demand for appraisal, whichever is later.



     Petition in the Court of Chancery.  If you have followed the steps above,
if appraisal rights are available, and the STAR merger is completed, you or
World Access may file a petition in the Court of Chancery of the State of
Delaware, within 120 days after the STAR merger is completed, demanding a
determination of the "fair value" of your shares. World Access has no obligation
to file this petition, and does not currently intend to file this petition. If
you wish to have the Court of Chancery determine the "fair value" of your
shares, you must file the petition. You will fail to perfect and lose your right
to appraisal if no petition is filed within 120 days after the STAR merger is
completed.



     The Court of Chancery may require you to submit your share certificates to
the Register in Chancery for notation of the appraisal proceeding. If you fail
to comply with this direction, the court may dismiss the appraisal proceedings
as to you.



     If you have complied with these procedures, the Court of Chancery will
determine whether you have complied with Delaware law and if you are entitled to
appraisal rights. After determining the STAR common stockholders entitled to
appraisal, the court will appraise the "fair value" of shares of STAR common
stock. "Fair value" will be determined exclusive of any element of value arising
from the completion or expectation of the STAR merger. The court may consider
all relevant factors including market value, asset value, dividends, earning
prospects, and the nature of the business. "Fair value" may be more than, the
same as, or less than the value of the merger consideration.



     The court will also determine if interest will be paid on the amounts to be
received by those STAR common stockholders whose shares have been appraised. The
costs of the appraisal proceeding may be determined by the court and taxed on
the parties as the court determines to be equitable. You also may apply to the
court to have the expenses of the appraisal proceeding incurred by you charged
pro rata against the value of all shares entitled to appraisal.



     Withdrawal of written demand for appraisal.  If you fail to perfect, lose
or withdraw your right to appraisal under Delaware law, you will receive the
merger consideration provided in the STAR merger agreement. You may withdraw
your written demand for appraisal by delivering a written withdrawal of your
demand for appraisal and acceptance of the merger consideration to World Access.
Any attempt to withdraw made more than 60 days after the STAR merger will
require the written approval of World Access. No appraisal proceeding filed with
the Court of Chancery may be dismissed as to you without approval of the court.



     Rights of STAR common stockholders demanding appraisal.  If you have
complied with the procedures of Delaware law as to appraisal, after the STAR
merger, you will not be entitled to:



        - vote your shares of STAR common stock subject to appraisal, or



        - dividends or distributions on your shares of STAR common stock subject
          to appraisal.



You will still be entitled to dividends or distributions payable on your shares
subject to appraisal as to a date prior to the STAR merger.

INTERESTS OF DIRECTORS, OFFICERS AND STOCKHOLDERS IN THE STAR MERGER


  Option plans and change in control arrangements


     STAR's stockholders should be aware that some of STAR's executive officers
and directors have interests in the STAR merger that are in addition to the
interests of the stockholders of STAR generally.



     Under STAR's 1997 Omnibus Stock Incentive Plan, the administrator of the
plan, which is a committee of the STAR board of directors, may provide for the
acceleration of the stock options, stock appreciation rights, stock units or
restricted shares granted to employees and outside directors in the event of a
change in control.



     Under STAR's 1996 Outside Director Nonstatutory Stock Option Plan, the STAR
board of directors may decide upon a change in control, that it is necessary or
desirable to accelerate the exercisability of outstanding options granted under
the plan. The STAR board of directors also has the discretion to terminate any
outstanding options that have been accelerated but not exercised during the
exercise period. The STAR merger constitutes a change in control under the 1997
Omnibus Stock Incentive Plan and the 1996 Outside Director Nonstatutory Stock
Option Plan.


     Other than as discussed below, the STAR board of directors does not intend
to accelerate options or other securities held by executive officers or
directors of STAR under the 1997 Omnibus Stock Incentive Plan or the 1996
Outside Director Nonstatutory Stock Option Plan.


     On January 3, 2000, STAR's non-executive stock option committee determined
that all of David Vaun Crumly's currently outstanding and future unvested
options would become exercisable five business days before a change in control.
The non-executive stock option committee accelerated Mr. Crumly's stock options
as an incentive for Mr. Crumly's continued employment with STAR through the
completion of the STAR merger. As of             , 2000, Mr. Crumly's options to
purchase                shares will accelerate upon the STAR merger. The
approximate value of his accelerated options as of             , 2000 is
$          .


  Change in control agreement


     In January 1996, STAR entered into an employment agreement with David Vaun
Crumly, whereby Mr. Crumly became Executive Vice President. Under his employment
agreement, Mr. Crumly will receive a bonus equal to the lesser of $1,500,000 or
a percentage of the monthly gross sales of accounts relating to customers
introduced to STAR by Mr. Crumly for the month before a sale transaction. The
percentage is either ten, twenty or thirty percent, depending on the size of the
monthly gross sales. STAR must pay the bonus in cash within 90 days of the sale
transaction, or if the stockholders of STAR receive stock in the transaction,
STAR can pay up to 50% of the bonus in STAR common stock or the shares of common
stock of the acquiring company. The STAR merger constitutes a sale transaction
under the agreement. As of             , 2000, Mr. Crumly's bonus is
approximately $          .


  Registration rights under voting agreement of Christopher Edgecomb


     World Access and Christopher Edgecomb entered into a voting and stock
transfer restriction agreement under which World Access granted to Mr. Edgecomb
unlimited "piggyback" registration rights. Mr. Edgecomb is entitled to include
the shares of World Access common stock he acquires in the STAR merger in any
registration of capital stock for the account of World Access or any selling
stockholder. World Access has also agreed to pay all of Mr. Edgecomb's expenses
in any piggyback registration, other than underwriting commissions and fees of
Mr. Edgecomb's legal counsel.


  Election of member of board of directors of World Access

     In the STAR merger agreement, World Access agreed to elect Christopher
Edgecomb to the board of directors of World Access or another person designated
by STAR and agreed to by World Access.

                    DESCRIPTION OF THE STAR MERGER AGREEMENT



     World Access and STAR entered into the original STAR merger agreement on
February 11, 2000. On June 7, 2000, the parties amended the original STAR merger
agreement to:



     - adjust the exchange ratio,



     - reduce World Access' short-term loan commitments to STAR by amounts
provided to STAR by WorldCom or any of its affiliates, and



     - provide that the condition to World Access' obligations under the STAR
merger agreement relating to STAR's sale of PT-1 will be satisfied if STAR sells
the assets of PT-1 to Counsel for net cash proceeds of at least $120.0 million
pursuant to the PT-1 asset sale agreement.



     The original STAR merger agreement as amended is referred to in this joint
proxy statement/prospectus as the STAR merger agreement. This is only a summary
of the STAR merger agreement and may not contain all of the information that is
important to you. The STAR merger agreement is attached to this joint proxy
statement/prospectus as Annex A. World Access and STAR urge you to read it
carefully.



DESCRIPTION OF THE STAR MERGER CONSIDERATION



     Upon completion of the STAR merger, each outstanding share of STAR common
stock will be automatically canceled and converted into the right to receive one
of two forms of merger consideration to be determined by World Access.



     - Under the first form of consideration, each STAR stockholder will be
       entitled to receive, for each share of STAR common stock, 0.386595 shares
       of World Access common stock, subject to upward adjustment if STAR sells
       PT-1 prior to the completion of the STAR merger for net cash proceeds in
       excess of $150.0 million.



     - Under the second form of merger consideration, each STAR stockholder will
       be entitled to receive, for each share of STAR common stock, the same
       total value as that paid in the first form of consideration. However,
       under the second form, each STAR stockholder will receive up to 60% of
       its consideration in World Access common stock and up to 40% of its
       consideration in cash. If World Access selects the second form of
       consideration, each STAR stockholder will receive the same percentages of
       stock and cash as other STAR stockholders.



     No fractional shares of World Access common stock will be issued in
connection with the STAR merger. Instead, STAR shareholders will receive cash,
without interest, instead of a fractional share of World Access common stock.
Shares of STAR common stock for which dissenters' rights of appraisal, if
available, have been perfected in accordance with Delaware law will not be
entitled to receive the merger consideration described above.



     Upon completion of the STAR merger, each outstanding STAR stock option or
warrant will be automatically converted into an option to purchase the number of
shares of World Access common stock that equals the number of shares of STAR
common stock covered under the STAR stock option or warrant multiplied by the
exchange ratio at a per share price equal to the exercise price specified in the
STAR stock option or warrant divided by the exchange ratio. The amount of World
Access common stock each STAR stock option or warrant will be convertible into,
is subject to upward adjustment if STAR sells PT-1 before to the completion of
the STAR merger for net cash proceeds in excess of $150.0 million. Each newly
issued World Access stock option will contain terms that are substantially
similar to the terms governing the original STAR stock option or warrant.

       agreement to be performed or complied with at or before completion of the

     - each of the parties must obtain all consents and approvals that are
       necessary to complete the STAR merger. However, if the failure of a party
       to use reasonable efforts to obtain such consents and approvals is the
       cause of the failure to obtain such consents and approvals, the party
       failing to use reasonable efforts must complete the STAR merger;



     - no material adverse effect with respect to either party shall have
       occurred since February 11, 2000; and



     - the waiting period applicable to the STAR merger under the

                                       73
<PAGE>   87


       the reclamation of STAR's capacity in the network, and STAR must have no
       further obligations or liabilities with respect to the network.



TERMINATION OF THE STAR MERGER AGREEMENT



     The STAR merger agreement may be terminated at any time before completion
of the STAR merger by either party for any of the following reasons:



     - by mutual written consent;



     - if the other party fails to comply with its material covenants or
       agreements in the STAR merger agreement and fails to cure such
       noncompliance within ten business days after receiving a notice of
       breach; however, the non-breaching party may not terminate the STAR
       merger agreement if the breaching party continues to use reasonable
       efforts to cure the breach;



     - if the other party has breached any of its representations or warranties,
       and the breach remains uncured for ten business days after receiving a
       notice of breach; however, the non-breaching party may not terminate the
       STAR merger agreement if the breaching party continues to use reasonable
       efforts to cure the breach;



     - if the STAR merger has not been completed by September 30, 2000, unless
       the failure to complete the STAR merger is the result of a breach of the
       STAR merger agreement by the party seeking to terminate the STAR merger
       agreement;



     - if any permanent injunction, order, decree or ruling by any governmental
       entity preventing the completion of the merger has become final and
       nonappealable; or



     - if the stockholders of World Access or STAR fail to approve the STAR
       merger agreement by the required vote.



     The STAR merger agreement may be terminated at any time prior to completion
of the STAR merger by STAR if, prior to the STAR stockholders vote and upon
three business days' prior notice to World Access, STAR's board of directors
determines that an acquisition proposal is a superior proposal. However, STAR's
termination of the STAR merger agreement is subject to the following conditions:



        - prior to termination and upon request by World Access, STAR negotiates
          with World Access regarding a revised proposal by World Access;


        - the STAR board of directors determines, during such three-day period
          and after considering the revised World Access proposal, that the
          acquisition proposal is a superior proposal; and


        - STAR pays the $14.0 million termination fee.



     The STAR merger agreement may be terminated at any time prior to completion
of the STAR merger by World Access if STAR:



     - is involved in a voluntary or involuntary bankruptcy or similar
       proceeding;



     - is subject to the appointment of a receiver or similar official;



     - is subject to a winding up or a liquidation decree or order;



     - shares a general assignment for the benefit of its creditors;

       recommendation or approves or recommends a superior proposal before the
       STAR stockholders meeting; or



     - is involved in an event of default under the anticipated short-term loan
       agreements between World Access and STAR.


                                       74
<PAGE>   88


PAYMENT OF TERMINATION FEE IF THE STAR MERGER AGREEMENT IS TERMINATED



     STAR must pay World Access a termination fee of $14.0 million if the STAR
merger agreement is terminated for the following reasons:



     - because the STAR board of directors determines that a competing
       acquisition proposal is a superior proposal;



     - if the STAR merger agreement is terminated by World Access because the
       STAR board of directors makes an adverse change in the STAR
       recommendation or approves or recommends a superior proposal; or



     - because the stockholders of STAR have not adopted the STAR merger
       agreement by the required vote and STAR enters into a definitive
       agreement with respect to a business combination with an entity other
       than World Access within 12 months after the termination of the STAR
       merger agreement.



EXTENSION, WAIVER AND AMENDMENT OF THE STAR MERGER AGREEMENT



     The STAR merger agreement may be amended by World Access and STAR at any
time before completion of the STAR merger. However, no amendment may be made
after adoption of the STAR merger agreement by the World Access and STAR
stockholders.

merger:



     - extend the time for the performance of any of the obligations or other
       acts of the other party under the STAR merger agreement;



     - waive any inaccuracies in representations and warranties of the other
       party; or

       in the STAR merger agreement.


                  STAR VOTING AGREEMENTS AND CREDIT AGREEMENTS



     This section of the joint proxy statement/prospectus describes the voting
agreements of Christopher E. Edgecomb and Samer Tawfik and the anticipated STAR
credit agreements.


EDGECOMB VOTING AGREEMENT


     World Access and Christopher E. Edgecomb have entered into a voting and
stock transfer restriction agreement, dated February 11, 2000, under which Mr.
Edgecomb has agreed to vote all of his shares of STAR common stock in favor of
the STAR merger and against any action that would not be in favor of the STAR
merger.



     Under the agreement, Mr. Edgecomb may not:



     - sell or transfer any of his shares of STAR common stock;



     - trade or take any position with respect to his shares of STAR common
       stock;



     - enter into any voting arrangement or understanding with respect to his
       shares of STAR common stock; or



     - take any action that would make his representations or warranties untrue
       or prevent him from performing any of his obligations.


                                       75
<PAGE>   89


     The agreement also prohibits Mr. Edgecomb from transferring or taking a
position in any of the shares of World Access common stock he receives in the
STAR merger for six months after the completion of the STAR merger or as long as
he is a member of the World Access board of directors. World Access has the
first right to assist Mr. Edgecomb in the sale of his shares to an "accredited
investor" or "qualified institutional buyer," as defined in the Securities
Exchange Act of 1934, as amended. However, if World Access is unable to arrange
for a sale within 30 days, Mr. Edgecomb may complete the sale.



     World Access has also agreed to provide Mr. Edgecomb piggyback registration
rights for Mr. Edgecomb's shares of World Access common stock that he is
restricted from selling under Rule 144 of the Securities and Exchange Act of
1934. Mr. Edgecomb can only exercise this right if he requests the registration
of at least 25% of his shares or shares having a value of at least $2.0 million.



     Mr. Edgecomb has also agreed to restrictions on the solicitation or
employment of STAR employees.


     The voting and stock transfer restriction agreement terminates upon the
termination of the STAR merger agreement in accordance with its terms.

TAWFIK VOTING AGREEMENT


     On February 11, 2000, World Access also entered into a voting and stock
transfer restriction agreement with Samer Tawfik. Under this agreement, Mr.
Tawfik has agreed to vote all of his shares of STAR common stock in favor of the
STAR merger and against any action that would not be in favor of the STAR
merger.



     Under the agreement, Mr. Tawfik may not:



     - sell or transfer any of his shares of STAR common stock, except that Mr.
       Tawfik can transfer up to 2,430,000 shares of his STAR common stock to
       unaffiliated third parties;



     - trade or take any position with respect to his shares of STAR common
       stock;



     - enter into any voting arrangement or understanding with respect to his
       shares of STAR common stock; or



     - take any action that would make his representations or warranties untrue
       or prevent him from performing any of his obligations.



     Mr. Tawfik may not transfer any of the shares of World Access common stock
he receives in the STAR merger agreement for six months after the completion of
the STAR merger. World Access has the first right to assist Mr. Tawfik in the
sale of his shares to an "accredited investor" or a "qualified institutional
buyer," as defined in the Securities Exchange Act of 1934. However, if World
Access is unable to arrange for a sale within 30 days, Mr. Tawfik may complete
the sale.


     The voting and stock transfer restriction agreement terminates upon the
termination of the STAR merger agreement in accordance with its terms.


     Because Mr. Edgecomb and Mr. Tawfik each hold a significant number of
shares of STAR common stock, there is a greater likelihood that the STAR merger
will be approved by the required vote of the STAR stockholders. Mr. Edgecomb's
voting agreement applies to           shares representing approximately      %
of the voting power for the STAR merger as of                , 2000. Mr.
Tawfik's voting agreement applies to           shares representing approximately
     % of the voting power for the STAR merger as of                , 2000. The
combined voting power for the STAR merger under the agreements of Mr. Edgecomb
and Mr. Tawfik is approximately      % as of                , 2000.

STAR CREDIT AGREEMENTS


     World Access expects to enter into a credit agreement with STAR which would
provide STAR with a short-term loan of up to $25.0 million. The loan will
provide an initial advance to STAR and additional advances, each of which will
be made in World Access' sole discretion. The loan will be secured by all
personal property of STAR, PT-1 and Helvey Com LLC, including all equipment,
inventory, Indefeasible Rights of Use in telecommunications cables and cable
systems, accounts receivable, and general intangibles of STAR, PT-1, and Helvey;
by a pledge of all capital stock owned by STAR in certain of its subsidiaries;
and by a pledge of all capital stock owned by PT-1 in certain of its
subsidiaries. The interest rate will be LIBOR plus 4% per year. The loan will be
due on the earlier of:



     - one year from the date of the STAR credit agreement; or



     - 90 days after the STAR merger agreement terminates.



     World Access also expects to enter into a credit agreement with STAR
Telecommunications Holding GmbH, which would provide STAR GmbH with a short-term
loan of $10.0 million. This loan will provide an initial advance to STAR GmbH
and additional advances, each of which will be made in World Access' sole
discretion. The loan will be secured by all personal property of STAR GmbH. STAR
will pledge all of its interest in STAR GmbH and STAR GmbH will pledge all of
its interest in STAR Telecommunications Deutschland GmbH and STAR
Telecommunications Network GmbH. The interest rate will be LIBOR plus 4% per
year. The loan will be due on the earlier of:



     - one year from the date of the STAR GmbH credit agreement; or



     - 90 days after the STAR merger agreement is terminated.



     World Access will reduce the amount of credit it provides to STAR or its
subsidiaries for each dollar of additional financing provided to STAR and its
subsidiaries by WorldCom Network Services up to an aggregate of $30.0 million.



                           INFORMATION REGARDING STAR



     STAR provides high-quality, competitively priced, long distance
telecommunication services to consumer and commercial retail customers as well
as to other telecommunications carriers located within the U.S. and Europe. In
Germany, STAR offers Internet service providers wholesale dial-up services along
with a range of support services including data center co-location and bandwidth
provisioning. STAR seeks to capitalize on the increasing demand for high-quality
international communications services which is being driven by the globalization
of the world's economies, the worldwide trend toward telecommunications
deregulation, and the growth of voice, data and Internet traffic.



     STAR was incorporated in Delaware on September 13, 1996. Additional
information regarding STAR is contained in STAR's filings with the Securities
and Exchange Commission pursuant to the Securities Exchange Act of 1934. See
"Where You Can Find More Information" on the inside front cover page of this
joint proxy statement/prospectus.



                                STAR LITIGATION



     On February 14, 2000 and March 1, 2000, identical class action complaints
were filed against STAR and Christopher E. Edgecomb, Mary A. Casey, Mark
Gershein, Gordon Hutchins, Jr., John R. Snedegar, Arunas A. Chesonis and Samer
Tawfik. The complaint alleged causes of action for breach of fiduciary duty
arising from approval of the STAR merger on the grounds that the consideration
to be received in the STAR merger was unfair, unconscionable and grossly
inadequate. On May 31, 2000, the Superior Court of the State of California of
the County of Santa Barbara granted STAR's demurrer on the grounds that the
plaintiff's complaints were legally deficient, effectively dismissing the
lawsuit. On July 14, 2000, the plaintiff filed a notice of appeal from that
judgment.


                                       77
<PAGE>   91


     On March 11, 1999, a proceeding was commenced by PT-1 by notice of petition
following the election by a PT-1 stockholder to dissent from STAR's merger with
PT-1 and following a demand for payment of the fair value of approximately
2,731,330 shares of PT-1 held by the stockholder. The proceeding was commenced
in the Supreme Court of the State of New York. The PT-1 stockholder is seeking
damages in accordance with his appraisal rights under New York law. On July 26,
2000, the Supreme Court of the State of New York of the County of Queens issued
a temporary restraining order in favor of the stockholder which prevents PT-1
from distributing any of the proceeds of the PT-1 asset sale to STAR unless PT-1
has first set aside a reserve in the amount of $37,649,800 in cash to satisfy
the stockholder's claim.



     From time to time, STAR is party to various legal proceedings, including
billing disputes and collection matters and actions brought by certain
terminated employees that arise in the ordinary course of business.

                       COMPARISON OF RIGHTS OF HOLDERS OF


                         WORLD ACCESS COMMON STOCK AND


                               STAR COMMON STOCK



     This section of the joint proxy statement/prospectus summarizes the
differences between the World Access common stock and STAR common stock. STAR
stockholders should read this entire document, and each companies' certificate
of incorporation, bylaws and the other documents referred to carefully for a
more complete understanding of the differences between the World Access common
stock and STAR common stock. For information on how to obtain these documents,
see "Where You Can Find More Information" on the inside front cover page.



     The rights of World Access' stockholders are governed by its certificate of
incorporation, as amended, its bylaws and the laws of the State of Delaware. The
rights of STAR stockholders are currently governed by its certificate of
incorporation, as amended and restated, its bylaws and the laws of the State of
Delaware. After the completion of the STAR merger, STAR stockholders will become
stockholders of World Access. Because STAR and World Access are both Delaware
corporations, after the STAR merger is completed, the rights of STAR's
stockholders will continue to be governed by Delaware law. The following
paragraphs compare the rights of World Access stockholders and STAR stockholders
under the certificates of incorporation and bylaws of World Access and STAR, as
applicable.



COMPARISON OF AUTHORIZED AND OUTSTANDING CAPITAL STOCK



     The authorized capital stock of World Access currently consists of
160,000,000 shares, of which 150,000,000 shares are common stock of $.01 par
value per share, and 10,000,000 shares of which are preferred stock of $.01 par
value per share. Note, however, that pursuant to this joint proxy
statement/prospectus, the World Access stockholders are being asked to approve
an amendment to the World Access certificate of incorporation that would
increase the number of shares of common stock World Access is authorized to
issue to 290,000,000. As of August 1, 2000, 61,707,277 shares of World Access
common stock were outstanding and 613,905 shares of World Access preferred stock
were outstanding.



     The authorized capital stock of STAR consists of 100,000,000 shares of
common stock, of which 58,656,802 shares were outstanding as of August 1, 2000
and 5,000,000 shares of preferred stock, of which no shares were outstanding as
of August 1, 2000.



COMPARISON OF CLASSES OF COMMON STOCK



     World Access and STAR each have one class of common stock issued and
outstanding. Holders of World Access common stock and holders of STAR common
stock are each entitled to one vote for each share held.



COMPARISON OF REQUIREMENTS FOR SPECIAL MEETING OF STOCKHOLDERS



     Special meetings of World Access may be called by World Access' board of
directors or an officer instructed by the board of directors to call a meeting.



     Special meetings of STAR may be called by the president of STAR and must be
called by the president or secretary of STAR at the request of a majority of the
board of directors.



COMPARISON OF REQUIREMENTS FOR ACTION BY WRITTEN CONSENT IN LIEU OF A
STOCKHOLDERS' MEETING



     Pursuant to the World Access certificate of incorporation, World Access
stockholders may not take action without a meeting by written consent except for
preferred stockholders.



     STAR stockholders may take action without a meeting only by unanimous
written consent of the stockholders entitled to vote on such action.


                                       79
<PAGE>   93


COMPARISON OF RECORD DATE FOR DETERMINING STOCKHOLDERS



     Both the World Access bylaws and the STAR bylaws provide that each of their
boards of directors may fix a record date that:



     - in the case of determination of the stockholders entitled to vote at any
       meeting of stockholders or adjournment of any meeting, may not be more
       than 60 days or less than ten days before the date of the meeting; and



     - in the case of any other action, may not be more than 60 days before any
       such action.



Furthermore, if the World Access board of directors or the STAR board of
directors do not fix a record date in the manner described above, then:



     - the record date for determining stockholders entitled to notice of or to
       vote at a meeting of stockholders will be at the close of business on the
       day after the day that notice is given, or, if notice is waived, at the
       close of business on the day after the day that the meeting is held; and



     - the record date for determining stockholders for any other purpose will
       be at the close of business on the day the board of directors adopt the
       related resolution.



COMPARISON OF PROCEDURES TO NOMINATE DIRECTORS



     The World Access bylaws require that board nominations be made by the board
of directors or a stockholder who gives timely notice to the secretary of World
Access. To give timely notice, a stockholder's nomination notice must be
received by the secretary of World Access at least 120 days before the one-year
anniversary of the date of the proxy statement in connection with the previous
year's annual meeting of stockholders. A nominating stockholder's notice must be
received by World Access no later than the close of business on the tenth day
following the earlier of:



     - the day on which notice of the upcoming meeting was mailed or given to
       the World Access stockholders; or



     - the day on which public disclosure of the date of the upcoming meeting
       was made by World Access if:



        - no annual meeting was held in the previous year;



        - the date of the upcoming annual meeting has changed by more than 30
          days from the date set forth in the previous year's proxy statement;
          or



        - the upcoming meeting is not an annual meeting.



     The STAR certificate of incorporation and bylaws are silent with respect to
the nomination of persons for election to the STAR board of directors.



COMPARISON OF NUMBER OF DIRECTORS



     The World Access amended certificate of incorporation and bylaws provide
that the World Access board of directors may not have less than three and not
more than 12 directors. The exact number of directors will be determined from
time to time by the World Access board of directors. Note, however, that in
connection with this joint proxy statement/prospectus, World Access is seeking
approval by its stockholders of an amendment to its certificate of incorporation
that would increase the maximum number of directors to 15.



     The STAR certificate of incorporation and bylaws provide that the number of
directors will be determined from time to time by the STAR board of directors.


                                       80
<PAGE>   94


COMPARISON OF CLASSIFIED BOARD OF DIRECTORS



     Each of World Access' and STAR's board of directors is currently divided
into three classes, as nearly equal in size as possible, in which each class of
directors is elected annually. Directors of World Access and STAR are elected
for a three year term and until their successors are elected and qualified.



     You should note, however, that in connection with this joint proxy
statement/prospectus, World Access is seeking the approval of its stockholders
to amend its certificate of incorporation to eliminate World Access' classified
board of directors. If this amendment is approved by the required vote of the
World Access stockholders, all World Access directors would be elected annually
to serve a one-year term. At an annual meeting in which a quorum is present, the
persons receiving a plurality of the votes cast by World Access stockholders
would be elected as the directors.



COMPARISON OF PROCEDURES FOR THE REMOVAL OF DIRECTORS



     The World Access bylaws provide that any director or the entire board of
directors may be removed at any time, with cause, by the holders of a majority
of the voting power of the shares entitled to vote at an election of directors.



     Delaware law provides that any director or the entire board of directors of
STAR may be removed for cause, by the holders of a majority of the shares
entitled to vote at an election of directors.



COMPARISON OF BOARD OF DIRECTORS VACANCIES



     The bylaws of both World Access and STAR provide that vacancies on the
board of directors may be filled by the vote of the majority of directors
remaining in office.



COMPARISON OF NOTICE REQUIREMENTS OF SPECIAL MEETINGS OF THE BOARD OF DIRECTORS



     The World Access bylaws provide that the chairman of the board, the
vice-chairman of the board, the president or a majority of directors then in
office may call special meetings of the board of directors. The bylaws do not
require a specific notice period, but only require that the notice provide
sufficient time for the convenient assembly of the directors.



     The STAR bylaws provide that special meetings may be called by the
president on ten days notice to each director by mail or 48 hours notice either
personally by telephone, telegram or facsimile. Special meetings must be called
in like manner and on like notice by the president or secretary upon the written
request of two directors, or the sole director if the board consists of only one
director.



COMPARISON OF PROCEDURES FOR AN AMENDMENT OF CERTIFICATE OF INCORPORATION AND
BYLAWS



     The World Access amended certificate of incorporation imposes a
super-majority voting requirement with respect to certain amendments. Any
amendment to the classified board provisions of the certificate of
incorporation, or any proposed change to the certificate or bylaws which is
inconsistent with such provision, requires the vote of holders of at least 75%
of the voting power of all shares entitled to vote in the election of directors,
voting as a single class. The World Access bylaws may be amended by either the
board of directors or stockholders of World Access.



     Except with respect to the corporate name, registered office, name of the
registered agent and purpose of the corporation, which require a majority vote,
the stockholders of STAR may amend the certificate of incorporation only by the
vote of at least 75% of the voting power of the outstanding shares entitled to
vote in the election of directors, voting as a single class. The STAR bylaws may
be amended by the STAR board of directors or by the vote of stockholders owning
75% of the shares of STAR.

                                   PROPOSAL 2



                       DESCRIPTION OF THE PT-1 ASSET SALE



     This section of the joint proxy statement/prospectus describes the proposed
sale by STAR of the assets of its wholly-owned subsidiary, PT-1, to Counsel.
This proposal is for the consideration of the STAR stockholders only.



BACKGROUND OF THE PT-1 ASSET SALE



     PT-1 constitutes 90% of the net book value of STAR. As a condition to World
Access' obligation to complete the STAR merger, STAR is required to sell PT-1
for net cash proceeds of at least $150.0 million or complete the sale of the
assets of PT-1 to Counsel pursuant to the PT-1 asset sale agreement for net cash
proceeds of at least $120.0 million. STAR has entered into an agreement with
Counsel to sell to Counsel, or one of its affiliates, certain assets of PT-1,
including the assumption of certain liabilities, for cash proceeds of $150.0
million, subject to adjustment based on increases or decreases in the accounts
payable or receivable of PT-1 and the net worth of the assets of PT-1 on the
closing date.



     On February 14, 2000, STAR and World Access issued a joint press release
announcing the STAR merger agreement and indicating that the sale of certain
STAR assets would be required. After the announcement, STAR began to receive
inquiries from potential purchasers regarding PT-1, including an inquiry from
Counsel. Following a series of preliminary discussions between representatives
of STAR and representatives of Counsel, on February 22, 2000, a representative
of STAR met with representatives of Counsel at an industry conference in
California to discuss the potential acquisition of the PT-1 assets by Counsel.



     On February 29, 2000, STAR engaged Kaufman Bros. to act as its exclusive
financial and merger advisor and investment banker in connection with the PT-1
asset sale. Kaufman Bros. reviewed the inquiries from potential acquirors of
PT-1 received after the February 14, 2000 press release and familiarized itself
with PT-1's operations. STAR received three offers for the sale of some or all
of the assets of PT-1 by the end of March, 2000. One offer was for the separate
acquisition of the portion of PT-1's business providing long distance services
accessible through a dialed prefix, the second offer was for PT-1's prepaid
calling card operations, and the third offer was made by Counsel for the entire
operations of PT-1. Working with Kaufman Bros., STAR evaluated each offer
carefully and determined that the offers for the individual component businesses
of PT-1 were not attractive because STAR believed there was more value in PT-1
as a whole company. As evidence of this, the STAR board of directors considered
that the combined value of the two offers for the component businesses of PT-1
was less than the offer STAR had received from Counsel for PT-1 as a whole
company. STAR was particularly concerned that the combined offers for the
separate component businesses of PT-1 would not provide net cash proceeds of at
least $150.0 million as required by the STAR merger agreement.



     On March 8, 2000, STAR met with Counsel in New York to discuss Counsel's
interest in PT-1. Representatives and financial advisors of STAR and Counsel
attended the meeting. At the meeting, Counsel indicated that it was serious
about the acquisition, that it was interested in moving quickly to close the
deal and that it wanted STAR to enter into an exclusive arrangement with
Counsel. STAR was unwilling to commit to an exclusive arrangement at that time,
but permitted Counsel to begin due


                                       84
<PAGE>   98


diligence. On March 18, 2000, STAR met with Counsel in Toronto, Canada, to
continue discussions. After the March 18, 2000 meeting, formal discussions on
the letter of intent began. The STAR board of directors held a meeting on March
24, 2000 to discuss the terms of the letter of intent and considered the
proposal at length. The STAR board of directors decided to continue negotiations
with Counsel and to obtain World Access' approval as required by the STAR merger
agreement. STAR and Counsel executed the letter of intent on March 29, 2000.



     On June 6, 2000, the STAR board of directors met to consider the definitive
PT-1 asset sale agreement. The STAR board of directors received an opinion from
Kaufman Bros. that the proposed PT-1 asset sale was fair from a financial point
of view to STAR's stockholders. The STAR board of directors also received advice
from Delaware legal counsel on its obligations regarding its duty of care and
its duty to exercise informed business judgment. At the meeting, the STAR board
of directors concluded that the PT-1 asset sale was fair to and in the best
interests of STAR and its stockholders. The STAR board of directors considered
many factors in making its decision, including the need to complete the PT-1
asset sale prior to and in connection with the close of the STAR merger and the
financial condition of STAR and need to raise funds to pay debt and fund
operations. The STAR board of directors also considered the potential benefits
and the potential risks of the PT-1 asset sale, including all material business,
financial, legal and market factors discussed below under the heading "STAR's
reasons for the PT-1 asset sale." The STAR board of directors voted to approve
the PT-1 asset sale agreement and the transactions contemplated by the PT-1
asset sale agreement and voted to recommend that the stockholders of STAR vote
for the approval and adoption of the PT-1 asset sale agreement and the
transactions contemplated by the PT-1 asset sale agreement.



     On June 7, 2000, the parties announced the execution of the PT-1 asset sale
agreement.



STAR'S REASONS FOR THE PT-1 ASSET SALE



     In approving the PT-1 asset sale, the STAR board of directors considered
the potential benefits of the PT-1 asset sale and the risks associated with the
PT-1 asset sale. All material business, financial, legal and market factors are
discussed below.



     After due deliberation, the STAR board of directors concluded that the PT-1
asset sale was fair to and in the best interests of STAR and its stockholders
based on all of the following material factors:



          The sale of PT-1 is a condition to the close of the STAR merger.  The
     STAR merger agreement requires that STAR sell PT-1 for net cash proceeds of
     at least $150.0 million or complete the sale of the assets of PT-1 to
     Counsel for net cash proceeds of at least $120.0 million. If STAR fails to
     sell PT-1 for net cash proceeds of at least $150.0 million or complete the
     sale of the assets of PT-1 to Counsel for net cash proceeds of at least
     $120.0 million, then World Access does not have to complete the STAR
     merger. The STAR board of directors has voted to approve the STAR merger
     and has determined that the completion of the STAR merger is fair to and in
     the best interests of STAR and its stockholders.



          The financial condition of STAR.  The STAR board examined the current
     financial condition of STAR and determined that STAR's cash flow situation
     and debt levels and debt maturities required the sale of certain non-core
     segments of STAR's operations. The PT-1 asset sale is a condition to the
     close of the STAR merger and STAR entered into the STAR merger agreement
     partly to alleviate its cash flow situation. In the event that the STAR
     merger does not close, and should STAR elect to proceed with the PT-1 asset
     sale, STAR expects that the sale of the assets of PT-1 will provide needed
     cash to allow STAR to continue its operations and growth.



          Improved focus on STAR's core business.  Historically, STAR has
     focused its operations on the wholesale international long distance market.
     Through acquisitions, including the acquisition of PT-1, STAR expanded its
     operations into the consumer and commercial retail long distance markets.
     If the STAR merger does not close, the PT-1 asset sale would enable STAR to
     focus on its wholesale


                                       85
<PAGE>   99

     international long distance business and continue to expand its network in
     order to improve operating margins.


     The STAR board of directors also considered the material risks associated
with completing the PT-1 asset sale, including the following, but concluded that
the advantages of the PT-1 asset sale far outweighed these risks:



     - The risk that Counsel might not have sufficient funds available to
       finance the purchase of PT-1's assets, though the STAR board of directors
       considered that at the time of its approval of the PT-1 asset sale,
       Counsel represented that it has sufficient resources; and



     - The risk that STAR may not receive net cash proceeds of $120.0 million
       from Counsel as required in the STAR merger agreement, though the STAR
       board of directors considered that at the time of its approval of the
       PT-1 asset sale, the PT-1 asset sale consideration would generate the
       necessary net cash proceeds.



     The above discussion of the information and factors considered by the STAR
board of directors only sets forth the material factors considered by the STAR
board of directors. The STAR board of directors considered many factors when
evaluating the PT-1 asset sale agreement and the PT-1 asset sale. The STAR board
of directors did not quantify, rank or attempt to assign relative weights to the
factors considered in reaching its determination. In addition, the STAR board of
directors conducted an overall analysis of the above factors, including a
thorough discussion with and questioning of STAR's management. The STAR board of
directors also considered management's analysis of the PT-1 asset sale based on
information received from STAR's legal, financial and accounting advisors. The
STAR board of directors considered all these factors as a whole, and considered
the factors overall to be favorable to STAR and to support its determination.



THE STAR BOARD OF DIRECTORS' RECOMMENDATION THAT STOCKHOLDERS APPROVE THE PT-1
ASSET SALE



     The STAR board of directors has carefully considered the advisability of
the PT-1 asset sale and believes that the terms of the PT-1 asset sale agreement
and the transactions contemplated by the PT-1 asset sale agreement are fair to
and in the best interests of STAR and its stockholders. The STAR board of
directors has approved the PT-1 asset sale agreement and the transactions
contemplated by the PT-1 asset sale agreement. The STAR board of directors
recommends that the stockholders of STAR vote for the approval and adoption of
the PT-1 asset sale agreement and the transactions contemplated by the PT-1
asset sale agreement.



OPINION OF STAR'S FINANCIAL ADVISOR REGARDING THE PT-1 ASSET SALE



     In connection with its consideration of the proposed PT-1 asset sale, STAR
requested that Kaufman Bros. advise the STAR board of directors with respect to
the fairness to the stockholders of STAR, from a financial point of view, of the
consideration to be paid by Counsel to PT-1 in the PT-1 asset sale.



     STAR selected Kaufman Bros. for a number of reasons, including its
familiarity with STAR and PT-1 and its experience and reputation in the areas of
valuation and financial advice, particularly in relation to transactions of the
size and nature of the PT-1 asset sale. Kaufman Bros. is an investment banking
firm which is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, leveraged buyouts,
negotiated underwritings, private placements and valuations for corporate and
other purposes. In the normal course of its business, Kaufman Bros. trades STAR
common stock for its own account or for the account of its customers and,
accordingly, may, from time to time, hold long or short positions in STAR common
stock.



     On May 25, 2000, Kaufman Bros. reviewed with the STAR board of directors
the financial analyses performed by Kaufman Bros. and delivered to the STAR
board of directors an oral opinion. The oral opinion was subsequently confirmed
by delivery of a written opinion, dated May 25, 2000, to the effect that, based
upon and subject to the considerations and limitations set forth in the opinion,
as of May 25,

                                       86
<PAGE>   100


2000, the consideration to be paid by Counsel to PT-1 in the PT-1 asset sale was
fair, from a financial point of view, to the stockholders of STAR.



     The following summary of the Kaufman Bros. opinion may not include all of
the information important to you. The full text of the opinion letter, dated May
25, 2000, delivered by Kaufman Bros. to the STAR board of directors, which sets
forth fully the assumptions made, general procedures followed, matters
considered and limits on the scope of review undertaken, is included as Annex G
to this joint proxy statement/prospectus and is incorporated herein by
reference. Kaufman Bros. has consented to the inclusion of the full text of its
opinion as Annex G to this joint proxy statement/prospectus. Holders of STAR
common stock are urged to read the Kaufman Bros. opinion carefully and in its
entirety.



     STAR did not place any limitation upon Kaufman Bros. with respect to the
procedures to be followed or factors to be considered in rendering its opinion.
In conducting its investigation and analysis and in arriving at its opinion,
Kaufman Bros. reviewed information and took into account the financial and
economic factors it deemed relevant and material under the circumstances. In
connection with its analysis, Kaufman Bros., among other things:



     - reviewed the PT-1 asset sale agreement in the form presented to the STAR
       board of directors;



     - reviewed internal financial information concerning the business and
       operations of PT-1 furnished to Kaufman Bros. for purposes of its
       analysis, as well as publicly available information, such as STAR's
       recent filings with the SEC;



     - reviewed forecasts and projections of PT-1 prepared or supplied by the
       management of STAR and PT-1 for the fiscal years ending December 31, 2000
       through December 31, 2005;



     - held discussions with executives of PT-1 and STAR concerning PT-1's
       historical and current financial condition, operating results, and future
       prospects;



     - visited PT-1's facility in Flushing, New York;



     - compared the financial position and operating results of PT-1 with those
       of other publicly traded companies Kaufman Bros. deemed reasonably
       comparable to PT-1;



     - compared the proposed financial terms of the PT-1 asset sale with the
       financial terms of other business combinations Kaufman Bros. deemed
       reasonably comparable to the proposed PT-1 asset sale;



     - performed such other financial studies, analyses, inquiries and
       investigations as it deemed appropriate.



     In addition, Kaufman Bros. took into account the manner in which the
financial terms of the PT-1 asset sale were negotiated by STAR and Counsel, the
terms of the merger between STAR and World Access as they relate to the PT-1
asset sale and the results of the various discussions held by STAR and Kaufman
Bros. with persons with a possible interest in acquiring PT-1.



     In arriving at its opinion, Kaufman Bros. assumed and relied upon, without
independent verification, the accuracy and completeness of all of the financial
and other information provided to it by or on behalf of PT-1, or obtained by
Kaufman Bros. from publicly available sources and upon the assurance of the
management of STAR and PT-1 that they were not aware of any information or facts
that would make any of this information incomplete or misleading. In conducting
its review, Kaufman Bros. did not conduct or obtain an independent evaluation or
appraisal of any of the assets or liabilities, contingent or otherwise, of PT-1,
nor was it furnished with any evaluation or appraisal. Kaufman Bros. assumed,
with STAR's consent, that:



     - the sale of PT-1 will be consummated in accordance with the terms set
       forth in the PT-1 asset sale agreement, without any amendments and
       without waiver by the parties thereto of any of the conditions to their
       respective obligations under the agreement; and


                                       87
<PAGE>   101


     - all regulatory and other approvals and third party consents required for
       consummation of the PT-1 asset sale will be obtained without material
       cost to STAR or PT-1.



     Kaufman Bros. assumed that the financial forecasts examined by it were
reasonably prepared, at the time of their delivery to Kaufman Bros., based upon
the best available estimates and good faith judgments of PT-1's and STAR's
respective senior managements as to the future performance of PT-1. In the
course of analyzing the PT-1 projections, Kaufman Bros. performed certain
sensitivity analyses to incorporate the results of the quarter ended March 31,
2000 and other information available since the time the projections were
delivered to Kaufman Bros. and prior to the date of the Kaufman Bros. opinion.



     Kaufman Bros. noted that its opinion was necessarily based upon the
financial, economic, market and other conditions as they existed and could be
evaluated by Kaufman Bros. on, and the information made available to it as of,
the date of its opinion. Kaufman Bros. has disclaimed any undertaking or
obligation to advise any person of any change in any fact or matter affecting
its opinion that is brought to its attention after the date of its opinion.
Although Kaufman Bros. evaluated the consideration to be paid by Counsel to PT-1
in the PT-1 asset sale from a financial point of view, Kaufman Bros. was not
asked to, and did not, recommend the specific consideration payable in the PT-1
asset sale, which was determined through negotiations between STAR and Counsel.



     The Kaufman Bros. opinion is for the information of the STAR board of
directors for its use in evaluating the fairness, from a financial point of
view, to the stockholders of STAR of the consideration to be paid by Counsel to
STAR in the PT-1 asset sale. The opinion does not constitute a recommendation as
to any action the STAR board of directors or any stockholder of STAR should take
in connection with the PT-1 asset sale or any aspect of the transaction. The
Kaufman Bros. opinion is not an opinion as to the structure, terms or effect of
any other aspect of the PT-1 asset sale or any transaction contemplated in
connection with the PT-1 asset sale or as to the merits of the underlying
decision of STAR to enter into the PT-1 asset sale agreement or any other
transaction.



     In preparing its opinion, Kaufman Bros. performed a variety of financial
and comparative analyses, including those described below. The summary of these
analyses does not purport to be a complete description of the analyses
underlying the Kaufman Bros. opinion or of the presentation by Kaufman Bros. to
the STAR board of directors. The preparation of a fairness opinion is a complex
analytical process involving various determinations as to the most appropriate
and relevant methods of financial analyses and the application of those methods
to the particular circumstances and, therefore, such an opinion is not readily
susceptible to summary description. Furthermore, in arriving at its opinion,
Kaufman Bros. did not attribute particular weight to any analysis or factor
considered by it, but rather made qualitative judgments as to the significance
and relevance of each analysis and factor. Accordingly, Kaufman Bros. believes
that its analysis must be considered as a whole and that selecting portions of
its analyses and factors, without considering all analyses and factors, could
create a misleading or incomplete view of the process underlying the preparation
of its opinion. In its analysis, Kaufman Bros. made numerous assumptions with
respect to the company, industry performance, general business, economic, market
and financial conditions and other matters, many of which are beyond PT-1's and
STAR's control. The estimates contained in its analyses and the valuation ranges
resulting from any particular analysis are not necessarily indicative of the
actual values or predictive of future results or values, which may be
significantly more or less favorable than those suggested by the analyses. In
addition, analyses relating to the value of businesses or securities do not
purport to be appraisals or to reflect the prices at which businesses or
securities actually may be sold. Accordingly, these analyses and estimates are
inherently subject to substantial uncertainty.



     The Kaufman Bros. opinion and analyses were only one of many factors
considered by the STAR board of directors in its evaluation of the PT-1 asset
sale and should not be viewed as determinative of the view of the STAR board of
directors or management of STAR with respect to the PT-1 asset sale or the
consideration to be paid by Counsel in the PT-1 asset sale.

     The following is a summary of the material financial analyses performed by
Kaufman Bros. in connection with rendering its opinion.



  Analysis of Selected Comparable Acquisition Transactions



     Using publicly available information, Kaufman Bros. analyzed certain
financial and operating information relating to the following ten selected
merger and acquisition transactions in the calling card and dial-around
telecommunications sector each of which were consummated in calendar years 1997
through 2000. The comparable transactions were chosen based on a review of
acquired companies that possessed general business, operating and financial
characteristics representative of companies in the industry in which PT-1
operates. Kaufman Bros. noted that none of the comparable transactions reviewed
was exactly comparable to the PT-1 asset sale and that the range of information
available for each comparable transaction varied from detailed information
relating to publicly registered companies, to limited and summary information
contained in public press releases relating to private companies. The comparable
transactions reviewed by Kaufman Bros. were (the purchaser is listed first and
is followed by the acquired company):



     Fiscal Year 2000


     EGlobe/Trans Global Communications



    Fiscal Year 1999


    DCI Telecommunications/Wavetech International


    Viatel/Destia Communications


    EGlobe/Coast International Telecom


    World Access/Comm/Net Holdings Corporation


    AT&T/Smartalk Teleservices


    EGlobe/TeleKey



    Fiscal Year 1998


    Teleglobe/Excel Communications


    Primus Telecommunications/Trescom International



     Fiscal Year 1997


     LCI International/USLD Communications



     For each comparable transaction, Kaufman Bros. calculated multiples of:



     - the market value of common equity plus book value of total debt and
       preferred stock minus total cash, referred to as Enterprise Value, of the
       acquired company to its last twelve months EBIT. EBIT is earnings before
       interest and taxes; and



     - Enterprise Value to the last twelve-month EBITA. EBITDA is earnings
       before interest, taxes, depreciation and amortization.



The last twelve-month earnings and balance sheet data items were based upon the
most recent quarterly publicly available information prior to the closing of the
respective comparable transaction. Kaufman Bros. then applied these multiples to
the last twelve-month financial results of PT-1 for the period ended March 31,
2000, to determine PT-1's Enterprise Value. Based upon these analyses:



     - The median multiple of Enterprise Value to last twelve-month EBIT for the
       comparable transactions is 17.4x;



     - The median multiple of Enterprise Value to last twelve-month EBITDA for
       the comparable transactions is 10.1x;



     - The implied Enterprise Value of PT-1, based upon applying these median
       multiples to PT-1's financial data, falls within the range of $151.2
       million to $159.2 million. Kaufman Bros. noted that the consideration to
       be paid by Counsel to PT-1 in the PT-1 asset sale was close to this
       range.


                                       89
<PAGE>   103


  Analysis of Selected Publicly Traded Companies



     Kaufman Bros. reviewed publicly available financial information, as of the
most recently reported period, and stock market information as of May 24, 2000,
for the following six publicly traded companies that Kaufman Bros. deemed
reasonably comparable based upon their general business and operating and
financial characteristics to PT-1:



     - Global Telecom Solutions;



     - Tricom SA;



     - IDT Corporation;



     - RSL Communications, LTD.;



     - Pacific Gateway Exchange; and



     - Dial-Thru International.



     Kaufman Bros. noted that none of the comparable companies is directly
comparable to PT-1.



     For each comparable company, Kaufman Bros. calculated multiples of
Enterprise Value to last twelve-month EBIT, last twelve-month EBITDA and to
total assets. Kaufman Bros. then applied these multiples to the last
twelve-month financial results of PT-1 for the period ended March 31, 2000,
furnished to Kaufman Bros.. Based upon these analyses:



     - the median multiple of Enterprise Value to last twelve-month EBIT for the
       comparable companies is 6.8x;



     - the median multiple of Enterprise Value to last twelve-month EBITDA for
       the comparable companies is 6.7x;



     - the median multiple of Enterprise Value to the total assets for the
       comparable companies is 1.2x; and



     - the implied Enterprise Value of PT-1 based upon these median multiples of
       PT-1's financial data falls within the range of $61.5 million to $161.8
       million. Kaufman Bros. noted that the consideration to be paid by Counsel
       to PT-1 in the PT-1 asset sale fell within this range.



  Discounted Cash Flow Analysis



     Kaufman Bros. performed a discounted cash flow analysis of PT-1, on a
stand-alone-basis, using the PT-1 projections for the fiscal years 2000 through
2005. In addition, Kaufman Bros. performed certain sensitivity analyses based
upon the PT-1 projections to incorporate the results of the quarter ended March
31, 2000 and certain other information available since the time the PT-1
projections were delivered to Kaufman Bros. and prior to the date of the Kaufman
Bros. opinion. A discounted cash flow analysis is a traditional valuation
methodology used to derive a valuation of a corporate entity by calculating the
estimated future free cash flows of the entity and discounting the cash flow
results back to the present. Free cash flows means earnings before interest,
taxes, depreciation and amortization less taxes, capital expenditures and
changes in working capital.



     In its discounted cash flow analyses, Kaufman Bros. estimated a terminal
value of free cash flow in 2005 using a perpetual annual growth rate of 3% and
discounted the stream of free cash flows during the forecast period together
with the estimated terminal value back to March 31, 2000 at discount rates
ranging from 23.0% to 26.0%. Selection of an appropriate discount rate is an
inherently subjective process and is affected by numerous factors. The discount
rates used by Kaufman Bros. were selected based upon PT-1's recent historical
financial results, current financial condition and the risk associated with PT-1
achieving its financial projections. This range of discount rates also reflects
an estimate of the cost of capital for PT-1, and the rates of return for
comparable public companies adjusted for market capitalization and industry.
This analysis produced Enterprise Values for PT-1 ranging from $149.7 million


                                       90

to $182.0 million. Kaufman Bros. noted that the consideration to be paid by
Counsel to PT-1 in the PT-1 asset sale fell within this range.



  Compensation



     Pursuant to the terms of Kaufman Bros.' engagement, STAR has paid to
Kaufman Bros. the sum of $50,000 and has agreed to pay Kaufman Bros. a cash fee
of 1% of the consideration paid by Counsel to STAR upon closing of the PT-1
asset sale less any amounts previously paid. STAR has also agreed to reimburse
Kaufman Bros. for its reasonable out-of-pocket expenses incurred in performing
its services, including the reasonable fees and expenses of its legal counsel,
and to indemnify Kaufman Bros. and related persons against certain liabilities
relating to or arising out of its engagement, including certain liabilities
under the federal securities laws.



INFORMATION ABOUT COUNSEL



     Counsel is a subsidiary of Counsel Corporation, Inc., an investment and
management company that specializes in Internet communication technologies and
other technology-based enterprises. The common stock of Counsel Corporation is
traded on the Nasdaq National Market under the symbol "CXSN."



PURCHASE PRICE



     Counsel will purchase all of PT-1's assets that relate to PT-1's debit card
and long distance services accessible through a dialed prefix for $150.0 million
in cash, subject to adjustment upward or downward to the extent that the net
value of the purchased assets, less the liabilities being assumed of PT-1 as of
the closing date, is greater or less than $47,589,862. In addition, the purchase
price is subject to adjustment to the extent that PT-1's accounts payable and
accounts receivable for the 30 days prior to close differ materially from the
figures for the 30 days prior to December 31, 1999. Counsel will only assume
some liabilities, including those liabilities itemized on PT-1's balance sheet
as accounts payable and accrued expenses, accrued taxes payable, short-term
debt, deferred revenue and long-term debt. On the closing date, Counsel will pay
STAR $150.0 million in cash, subject to adjustment as indicated above and less
$22.5 million which will be held in escrow pursuant to an escrow agreement
between STAR and Counsel. One quarter of the escrow amount of $22.5 million,
less any amounts paid to Counsel in connection with indemnification claims made
by Counsel, will be released to STAR on each six month anniversary of the
closing date of the PT-1 asset sale. Counsel must pay STAR 100% of the escrow
amount, less any amounts paid to Counsel in connection with indemnification
claims made by Counsel, when the STAR merger closes and when World Access
assumes STAR's and PT-1's obligations under the PT-1 asset sale agreement.



MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE PT-1 ASSET SALE



     The PT-1 asset sale is a taxable transaction to STAR. STAR expects that the
net proceeds of the PT-1 asset sale will be substantially greater than the
adjusted tax basis of the PT-1 assets and that, accordingly, PT-1 will recognize
substantial gain from the sale, which will only be partially offset by STAR's
net operating loss carryovers. Therefore, STAR will have income tax liability
from the sale of PT-1's assets of between $6-$12 million.



ACCOUNTING TREATMENT OF THE PT-1 ASSET SALE



     STAR intends to account for the PT-1 asset sale as a sale of assets in
accordance with United States generally accepted accounting principles. STAR
expects to record a loss on its financial statements for the difference between
the total proceeds from the sale of the PT-1 assets and the net book value of
those assets, even though for tax purposes, STAR will have income tax due from
the sale of the assets.

REGULATORY FILINGS AND APPROVALS REQUIRED TO COMPLETE THE PT-1 ASSET SALE



     The PT-1 asset sale is subject to the requirements of the Hart-Scott-Rodino
Act. The Hart-Scott-Rodino Act prevents the completion of transactions until
required information and materials are furnished to the Antitrust Division of
the Department of Justice and the Federal Trade Commission and the appropriate
waiting periods end or expire. STAR and Counsel have filed the required
information and materials with the Antitrust Division of the Department of
Justice and the Federal Trade Commission. The Department of Justice and Federal
Trade Commission granted an early termination of the waiting period, effective
July 10, 2000. No further action under the Hart-Scott-Rodino Act is required, as
long as the PT-1 asset sale is completed by July 10, 2001.



     The Antitrust Division of the Department of Justice or the Federal Trade
Commission may challenge the PT-1 asset sale on antitrust grounds either before
or after expiration of the waiting period. Other persons could take action under
the antitrust laws, to enjoin the PT-1 asset sale. Additionally, at any time
before or after the completion of the PT-1 asset sale or the expiration of the
waiting period, any state could take action under the antitrust laws.



     The PT-1 asset sale is also subject to obtaining authorizations, consents,
certifications or other approvals from the Federal Communications Commission and
the state public utility commissions in the states of New York, California,
Florida, New Jersey and Texas. The required filings have been made and STAR and
Counsel are waiting for comments and approvals from the applicable governmental
agencies.



     Other than the approvals described above and compliance with the applicable
corporate laws of Delaware, we are not aware of any other material governmental
or regulatory approval required for completion of the PT-1 asset sale.


RIGHTS OF DISSENTING STAR STOCKHOLDERS


     STAR stockholders will not be entitled to dissenters' rights under Delaware
law in connection with the PT-1 asset sale.



STAR OFFICER AGREEMENT TO VOTE SHARES IN FAVOR OF THE PT-1 ASSET SALE



     Mr. Edgecomb has agreed to vote all of his shares of STAR common stock in
favor of the PT-1 asset sale. Mr. Edgecomb held approximately [     %] of the
outstanding capital stock of STAR as of the STAR record date representing
approximately   % of the combined voting power for the PT-1 asset sale. Because
Mr. Edgecomb holds a significant number of shares of STAR common stock, there is
a greater likelihood that the PT-1 asset sale will be approved by the required
vote of the STAR stockholders.



INTERESTS OF STAR'S DIRECTORS, OFFICERS, STOCKHOLDERS AND FINANCIAL ADVISORS



     STAR stockholders should be aware that some of STAR's directors, officers
and stockholders have interests in the STAR merger, of which the PT-1 asset sale
is a condition precedent, that are in addition to all other stockholders of
STAR.



     Kaufman Bros., STAR's financial advisor has issued a fairness opinion to
the STAR board of directors in connection with the PT-1 asset sale. After the
PT-1 asset sale is completed, Kaufman Bros. will be paid a transaction fee of 1%
of the PT-1 asset sale price. Regardless of whether the PT-1 asset sale is
completed, STAR will reimburse Kaufman Bros. for reasonable fees and expenses of
Kaufman Bros.' counsel and all of Kaufman Bros.' reasonable travel and other
out-of-pocket expenses incurred in connection with the PT-1 asset sale.



                  DESCRIPTION OF THE PT-1 ASSET SALE AGREEMENT



     This section of the joint proxy statement/prospectus is a summary of the
material terms of the PT-1 asset sale agreement and does not contain all of the
information that is important to you. Counsel, STAR and PT-1 urge you to read
the PT-1 asset sale agreement carefully.

<PAGE>   106


THE PT-1 ASSET SALE CLOSING DATE



     The closing of the PT-1 asset sale shall take place as soon as possible
after all required regulatory approvals are obtained, but no later than five
days after satisfaction of the conditions in the PT-1 asset sale agreement or at
a later time agreed to by the parties.


PURCHASE PRICE


     Counsel will purchase all of PT-1's assets that relate to PT-1's debit card
and long distance services accessible through a dialed prefix for $150.0 million
in cash, subject to adjustment upward or downward to the extent that the net
value of the purchased assets, less the liabilities being assumed of PT-1 as of
the closing date, is greater or less than $47,589,862. In addition, the purchase
price is subject to adjustment to the extent that PT-1's accounts payable and
accounts receivable for the 30 days prior to close differ materially from the
figures for the 30 days prior to December 31, 1999. Counsel will only assume
some liabilities, including those liabilities itemized on PT-1's balance sheet
as accounts payable and accrued expenses, accrued taxes payable, short-term
debt, deferred revenue and long-term debt. On the closing date, Counsel will pay
STAR $150.0 million in cash, subject to adjustment as indicated above and less
$22.5 million which will be held in escrow pursuant to an escrow agreement
between STAR and Counsel. One quarter of the escrow amount of $22.5 million,
less any amounts paid to Counsel in connection with indemnification claims made
by Counsel, will be released to STAR on each six month anniversary of the
closing date of the PT-1 asset sale. Counsel must pay STAR 100% of the escrow
amount, less any amounts paid to Counsel in connection with indemnification
claims made by Counsel, when the STAR merger closes and when World Access
assumes STAR's and PT-1's obligations under the PT-1 asset sale agreement.

     Counsel will assume liabilities that:



     - are itemized on the balance sheet of PT-1 as of the closing date, as

       deferred revenue and long-term debt;



     - are liens for PT-1 taxes not yet due and payable;



     - relate to claims for payphone compensation to the extent it is accrued
       and itemized on the balance sheet of PT-1 as of the closing date; and



     - arose after the closing date under the agreements, contracts, leases,

       Counsel.



     Counsel will not assume, and PT-1 will retain, liabilities:



     - itemized on the balance sheet of PT-1 as of the closing date, as
       liabilities due to carriers, intercompany payables and deferred tax
       liability;



     - for taxes for periods prior to the closing date and income taxes in
       connection with this sale of assets;



     - relating to employee, post-employment or retiree benefits or compensation
       arrangements existing prior to the closing date;



     - relating to any action, lawsuit, investigation or proceeding relating to
       PT-1 that is pending as of the closing date of the PT-1 asset sale, or
       arises from the acts or omissions of PT-1 or from strict liability or
       liability under law or contract imposed on PT-1 or the assets being
       purchased by Counsel prior to the closing date, other than the
       liabilities for payphone compensation to the extent they are assumed by
       Counsel as described above; and



     - relating to any deferred tax asset or PT-1's satellite offices.

                                   PROPOSAL 3



                THE MERGER BETWEEN WORLD ACCESS AND WORLDXCHANGE



     This section of the joint proxy statement/prospectus describes the proposed
merger between World Access and WorldxChange. This proposal is for the
consideration of the World Access stockholders. While we believe that the
description covers the material terms of the WorldxChange merger and the related
transactions, this summary may not contain all of the information that is
important to you. You should read this entire document and the other documents
we refer to carefully for a more complete understanding of the WorldxChange
merger.



BACKGROUND OF THE WORLDXCHANGE MERGER



     In the spring of 1999, Roger B. Abbott, Chief Executive Officer of
WorldxChange, met with John D. Phillips and W. Tod Chmar in Atlanta, Georgia. At
this meeting, Mr. Phillips explained his views regarding certain trends in the
international long distance industry, including the likely consolidation among
international long distance providers. Mr. Phillips expressed his desire to make
World Access a leader in the movement toward consolidation of the international
long distance industry and asked Mr. Abbott to consider a possible business
combination involving World Access and WorldxChange. No agreement regarding a
possible transaction was reached at this meeting, but the parties kept in
contact with periodic telephone conversations throughout the summer and
remainder of 1999.


     On December 14, 1999, after World Access acquired FaciliCom International,
Inc. and entered into a definitive agreement to acquire Long Distance
International, Inc., Mr. Abbott called Mr. Phillips regarding a possible
transaction. During numerous phone calls over the next few weeks, the parties
worked through the basic economic terms of a transaction and instructed their
representatives to begin working on a definitive merger agreement.

                                       97
<PAGE>   111


     During the month of January and into the early part of February, the
parties worked on the definitive merger agreement and conducted their respective
due diligence investigations of the other party. On January 18, 2000, Roger
Abbott and Walter Anderson, the Chairman of the board of WorldxChange, met with
John D. Phillips and W. Tod Chmar in Atlanta to discuss Mr. Phillips' vision for
the combined company.



     On February 8, 2000, the World Access board of directors met by telephonic
conference call to receive an update from World Access management on, and to
discuss the terms of, the proposed transaction with WorldxChange. On February
11, 2000, the World Access board of directors met again by telephonic conference
call to consider the merger with WorldxChange. At this meeting, management
reviewed, for the board of directors, the strategic reasons for a business
combination with WorldxChange and management and legal counsel described the
specific terms of the proposed merger agreement. During this meeting, Donaldson,
Lufkin & Jenrette Securities Corporation, or Donaldson, Lufkin & Jenrette gave
its oral opinion as to the fairness of the consideration to be paid by World
Access pursuant to the merger agreement. The board of directors also received
summaries of the results of World Access' due diligence investigation of
WorldxChange. After the foregoing, the World Access board of directors
unanimously approved the WorldxChange merger agreement and the transactions
contemplated thereby and unanimously agreed to recommend its adoption to the
stockholders of World Access. On February 11, 2000, Donaldson, Lufkin & Jenrette
forwarded its written opinion regarding the fairness of the consideration to be
paid by World Access pursuant to the merger agreement to the members of the
board of directors of World Access.



     On February 5, 2000, the WorldxChange board of directors met by telephonic
conference call to consider the merger with World Access. During this meeting,
management reviewed the strategic reasons for a business combination with World
Access and described the specific terms of the proposed merger agreement. After
the foregoing, the WorldxChange board approved the WorldxChange merger agreement
and the transactions contemplated thereby.



WORLD ACCESS' REASONS FOR THE WORLDXCHANGE MERGER



     In approving the WorldxChange merger, the World Access board of directors
considered the potential benefits of the WorldxChange merger and the risks
associated with the WorldxChange merger. All material business, financial, legal
and market factors are discussed below. In view of the number and wide variety
of factors considered in connection with its evaluation of the WorldxChange
merger, the World Access board of directors did not consider it practicable to,
nor did it attempt to, quantify or otherwise assign relative weights to the
material factors considered in reaching its determination. The World Access
board of directors viewed its position and recommendation as being based on the
totality of the information and factors presented to and considered by it. In
addition, individual directors may have given different weight to different
information and factors.



     The World Access board of directors believes that the WorldxChange merger
is fair to and in the best interests of World Access and its stockholders for
the following reasons:



     The financial terms of the WorldxChange merger.  The World Access board of
directors considered information concerning the business, earnings, operations,
financial condition and prospects of World Access and WorldxChange,
individually, on a combined basis, and in conjunction with the STAR merger. The
board determined to approve the WorldxChange merger agreement and the
transactions contemplated thereby based on its consideration of these factors
without taking into account the STAR merger. The board of directors also
considered the opinion of Donaldson, Lufkin & Jenrette as to the fairness to
World Access, from a financial point of view, of the consideration to be paid by
World Access pursuant to the WorldxChange merger agreement.



     WorldxChange's global communications network.  The World Access board of
directors considered WorldxChange's presence in Europe and the Pacific Rim and
the potential for entry into additional countries. The board believes
WorldxChange's retail presence in the United Kingdom will accelerate the
implementation of World Access' strategy to increase its retail
telecommunications services throughout

                                       98
<PAGE>   112


Europe. The board of directors also considered the technical capabilities, cost
effectiveness, expansion possibilities and available capacity of WorldxChange's
telecommunications network in multiple countries, ownership interest in undersea
cable telecommunications systems and indefeasible rights of use in additional
undersea cable systems.



     Industry trend toward consolidation.  The World Access board of directors
considered the status of the international telecommunications services industry
and the likely trend toward consolidation of service providers. It considered
the potential significant cost savings to be achieved as a result of the
WorldxChange merger in order to provide global retail telecommunications
services at competitive rates.



     WorldxChange's international presence.  The World Access board of directors
considered the compatibility of WorldxChange's operations in Australia, Canada,
the Netherlands, New Zealand and the United Kingdom with World Access' existing
operations. The board of directors also considered WorldxChange's agreements for
telecommunications services in Belgium, Chile, France, Germany and Guatemala in
light of potential expansion. The combination of World Access and WorldxChange
would result in a combined network covering 18 countries worldwide. This
increased international presence accelerates World Access' strategy to increase
its non-U.S. services.



     Growing retail operations and diversified revenues.  The World Access board
of directors considered WorldxChange's growing retail operations, which would be
made available to World Access in the future. WorldxChange is currently serving
more than 550,000 residential and commercial retail customers each month.
Additionally, the World Access board of directors believes that WorldxChange
would strengthen World Access' position outside of North America because more
than 40% of WorldxChange's revenues originate outside of North America.



     The World Access board also considered the following potentially negative
factors but concluded they were outweighed by the positive factors described
above:



     Risks associated with integration.  The World Access board of directors
considered the risk that World Access would be unable to effectively integrate
the technical operations and management of World Access and WorldxChange.



     Risk of not achieving profitability.  The World Access board of directors
considered the risk that the combined company may not be profitable. Both World
Access and WorldxChange had losses in the first quarter of 2000. Despite
expected cost savings from the WorldxChange merger, the combined company may
continue to have losses which may cause the price of the World Access common
stock to decline.



THE WORLD ACCESS BOARD OF DIRECTORS' RECOMMENDATION THAT STOCKHOLDERS APPROVE
THE WORLDXCHANGE MERGER



     The World Access board of directors has carefully considered the
advisability of the WorldxChange merger and believes that the terms of the
WorldxChange merger are fair to, and that the WorldxChange merger is in the best
interests of, the stockholders of World Access. The board of directors of World
Access has unanimously approved the WorldxChange merger agreement and the
transactions contemplated by the WorldxChange merger agreement and unanimously
recommends that the stockholders of World Access vote for the approval and
adoption of the WorldxChange merger agreement and the transactions contemplated
by the WorldxChange merger agreement.



WORLDXCHANGE'S REASONS FOR THE WORLDXCHANGE MERGER



     The WorldxChange board of directors believes that the WorldxChange merger
is fair to and in the best interests of WorldxChange's stockholders for the
following reasons:



     - The WorldxChange merger provides WorldxChange shareholders with an amount
       of World Access shares, in a tax-free exchange, which, based on the World
       Access share price at the time the WorldxChange merger agreement was
       signed, represented a premium over the most recent price at which
       WorldxChange sold shares of its capital stock;


                                       99
<PAGE>   113


     - WorldxChange shareholders will be able to participate in the potential
       growth of World Access' business after the WorldxChange merger and to
       benefit from the potential appreciation in the value of World Access
       common stock; and



     - WorldxChange shareholders will have the liquidity of publicly traded
       World Access shares in place of their WorldxChange shares, which are not
       publicly traded.



     In reaching its decision to approve the WorldxChange merger agreement and
the proposed WorldxChange merger, the WorldxChange board consulted with
WorldxChange management and its advisors and considered the following factors:



     - The belief of the WorldxChange board that WorldxChange's
       telecommunications equipment and other assets, together with
       WorldxChange's presence in key European markets, would provide the
       combined company with opportunities for growth superior to those of
       WorldxChange as an independent company;



     - The fact that WorldxChange requires significant additional financing to
       fund operating cash needs and continue growing, and the belief of the
       WorldxChange board that WorldxChange has limited ability to obtain this
       needed capital as an independent company;



     - The belief of the WorldxChange board that the terms of the merger
       agreement, including the value of the World Access stock to be exchanged
       for the shares of WorldxChange common stock, are fair to and in the best
       interests of the WorldxChange shareholders;



     - The fact that WorldxChange had not previously been successful in entering
       into a satisfactory agreement with other potential acquirors or strategic
       partners; and



     - The belief of the WorldxChange board that the combined company would have
       a greater ability to serve customers and provide greater opportunities
       for employees than WorldxChange as an independent company.



The WorldxChange board also considered the following potentially negative
factors but concluded that they were outweighed by the positive factors
described above:



     - The risk that World Access's stock price would decline between the
       signing of the merger agreement and the closing of the merger, resulting
       in the WorldxChange shareholders receiving less value for their
       WorldxChange shares;



     - The risk that the WorldxChange merger would not be completed in a timely
       manner or at all and that the public announcement of the merger could
       hinder WorldxChange's ability to attract and retain key employees; and



     - The risk that, after WorldxChange committed to complete the merger, a
       more attractive strategic alternative would become available to the
       Company.



     Based on all of the above factors and considerations, the WorldxChange
board concluded that the WorldxChange merger was advisable, fair to, and in the
best interests of WorldxChange and its shareholders and that WorldxChange should
proceed with the WorldxChange merger.



OPINION OF WORLD ACCESS' FINANCIAL ADVISOR REGARDING THE WORLDXCHANGE MERGER



     World Access asked Donaldson, Lufkin & Jenrette, in its role as financial
advisor, to render an opinion to the World Access board as to the fairness, from
a financial point of view, to World Access of the consideration to be paid by
World Access. On February 11, 2000, Donaldson, Lufkin & Jenrette rendered an
oral opinion to World Access' board of directors, which was subsequently
confirmed in writing as of the same date, to the effect that, as of the date of
the opinion, and based upon and subject to the assumptions, limitations and
qualifications set forth in the opinion, the consideration to be paid by World
Access pursuant to the WorldxChange merger agreement was fair to World Access,
from a financial point


                                       100
<PAGE>   114


of view. The full text of Donaldson, Lufkin & Jenrette's opinion is attached as
Annex D to this joint proxy statement/prospectus.



     Donaldson, Lufkin & Jenrette expressed no opinion as to the price at which
World Access common stock would actually trade at any time. Donaldson, Lufkin &
Jenrette's opinion did not address the relative merits of the WorldxChange
merger and the other business strategies considered by the World Access board of
directors nor did it address the decision of the World Access board of directors
to proceed with the WorldxChange merger. Donaldson, Lufkin & Jenrette's opinion
did not constitute a recommendation to any World Access stockholder as to how
such stockholder should vote on the WorldxChange merger.



     World Access and WorldxChange determined the consideration to be paid by
World Access in arm's length negotiations, in which Donaldson, Lufkin & Jenrette
advised World Access.



     World Access selected Donaldson, Lufkin & Jenrette as its financial advisor
because Donaldson, Lufkin & Jenrette is an internationally recognized investment
banking firm that has substantial experience providing strategic advisory
services. Donaldson, Lufkin & Jenrette was not retained as an advisor or agent
to the stockholders of World Access or any other person. As part of its
investment banking business, Donaldson, Lufkin & Jenrette is regularly engaged
in the valuation of businesses and securities in connection with mergers,
acquisitions, underwritings, sales and distributions of listed and unlisted
securities, private placements and valuations for corporate and other purposes.
World Access did not impose any restrictions or limitations upon Donaldson,
Lufkin & Jenrette with respect to the investigations made or the procedures
followed by Donaldson, Lufkin & Jenrette in rendering its opinion.



     In arriving at its opinion, Donaldson, Lufkin & Jenrette:



     - reviewed the draft dated February 10, 2000 of the WorldxChange merger
       agreement and assumed the final form of that agreement would not vary in
       any respect material to Donaldson, Lufkin & Jenrette's analysis;



     - reviewed financial and other information that was publicly available or
       furnished to it by World Access and WorldxChange, including information
       provided during discussions with their respective managements, which
       included certain financial projections of each of World Access and
       WorldxChange that were prepared by World Access' management;



     - compared certain financial and securities data of World Access and
       WorldxChange with various other companies whose securities are traded in
       public markets;



     - reviewed the historical stock prices and trading volumes of the common
       stock of World Access;



     - reviewed prices paid in selected other business combinations; and



     - conducted other financial studies, analyses and investigations as
       Donaldson, Lufkin & Jenrette deemed appropriate for purposes of rendering
       its opinion.



     In rendering its opinion, Donaldson, Lufkin & Jenrette relied upon and
assumed the accuracy and completeness of all of the financial and other
information that was available to it from public sources, that was provided to
it by World Access and WorldxChange or their respective representatives, or that
was otherwise reviewed by it. Donaldson, Lufkin & Jenrette relied upon the
estimates of the management of World Access of the operating synergies
achievable as a result of the WorldxChange merger. Donaldson, Lufkin & Jenrette
also assumed that the financial projections of World Access and WorldxChange
supplied to it were reasonably prepared on the basis reflecting the best
currently available estimates and judgments of the management of World Access as
to the future operating and financial performance of World Access and
WorldxChange. Donaldson, Lufkin & Jenrette expressed no opinion with respect to
such forecasts or the assumptions on which they were based, and Donaldson,
Lufkin & Jenrette did not assume any responsibility for making any independent
evaluation or appraisal of the assets or liabilities of World Access or for
making any independent verification of any of the information reviewed by
Donaldson, Lufkin & Jenrette. Donaldson, Lufkin & Jenrette also did not assume
any responsibility for making any independent investigation of any legal matters
affecting World Access or WorldxChange and assumed the


                                       101
<PAGE>   115


correctness of all legal advice given to each of them and to World Access' board
of directors, including advice as to the tax consequences of the WorldxChange
merger. Donaldson, Lufkin & Jenrette assumed that the WorldxChange merger would
be accounted for as a purchase under generally accepted accounting principles
and that it would qualify as a tax-free reorganization for U.S. federal income
tax purposes.



     Donaldson, Lufkin & Jenrette's opinion is necessarily based upon economic,
market, financial and other conditions as they existed on, and on information
available to Donaldson, Lufkin & Jenrette as of, the date of its opinion.
Donaldson, Lufkin & Jenrette states in its opinion that, although subsequent
developments may affect its opinion, Donaldson, Lufkin & Jenrette does not have
any obligation to update, revise or reaffirm its opinion.



SUMMARY OF FINANCIAL ANALYSES PERFORMED BY DONALDSON, LUFKIN & JENRETTE



     The following is a summary of the financial analyses Donaldson, Lufkin &
Jenrette presented to the World Access board of directors on February 11, 2000
in connection with the preparation of Donaldson, Lufkin & Jenrette's opinion. No
company or transaction Donaldson, Lufkin & Jenrette used in the analyses
described below is directly comparable to World Access, WorldxChange or to the
WorldxChange merger. In addition, mathematical analysis such as determining the
mean or median is not in itself a meaningful method of using selected company or
transaction data. The analyses Donaldson, Lufkin & Jenrette performed are not
necessarily indicative of actual values or future results, which may be
significantly more or less favorable than suggested by these analyses. The
information summarized in the tables which follow should be read in conjunction
with the accompanying text. For purposes of the following analyses, Donaldson,
Lufkin & Jenrette used the February 9, 2000 closing price of the World Access
common stock of $22.88 per share.


1. CONSIDERATION PAID ANALYSIS


     Donaldson, Lufkin & Jenrette reviewed the consideration to be paid by World
Access pursuant to the WorldxChange merger agreement by using an exchange ratio
of (i) 0.6583, which assumes an average stock price of at least $20.38 per share
and is referred to as the initial exchange ratio for the ten-day period ending
at the close of trading on the second trading day preceding the closing, which
is referred to as the average period, and (ii) 1.1666, which assumes an average
stock price of less than $20.38 per share during the averaging period and the
issuance of the maximum number of contingent shares on the first anniversary of
the completion of the WorldxChange merger, which is referred to as the maximum
exchange ratio. In reviewing the consideration to be paid by World Access,
Donaldson, Lufkin & Jenrette used the closing stock price on February 9, 2000 of
$22.88 per share to determine the consideration to be paid based on the initial
exchange ratio and $11.50 per share, the floor price, to determine the
consideration to be paid based on the maximum exchange ratio.



2. COMPARABLE PUBLICLY TRADED COMPANY ANALYSIS



     Donaldson, Lufkin & Jenrette analyzed the market values and trading
multiples of selected publicly traded emerging multinational carriers that
Donaldson, Lufkin & Jenrette believed were reasonably comparable to WorldxChange
based on business and certain financial characteristics. These comparable
companies consisted of:


<TABLE>
    <S>      <C>
    (i)      IDT Corporation;
    (ii)     Pacific Gateway Exchange, Inc.;
    (iii)    PRIMUS Telecommunications Group, Incorporated;
    (iv)     RSL Communications, Ltd.; and
    (v)      Startec Global Communications Corporation.
</TABLE>


     In examining these comparable companies, Donaldson, Lufkin & Jenrette
calculated the enterprise value of each company as a multiple of its respective:
(i) last quarter annualized revenue; (ii) projected calendar year 2000 revenue;
(iii) gross property, plant and equipment and (iv) net property plant and
equipment. The enterprise value of a company is equal to the value of its
fully-diluted common equity plus

                                       102
<PAGE>   116


debt and the liquidation value of outstanding preferred stock, if any, minus
cash and the value of certain other assets, including minority interests in
other entities. All historical data was derived from publicly available sources
as of February 9, 2000 and all projected data was obtained from Wall Street
research reports.



     Donaldson, Lufkin & Jenrette performed this analysis in order to compare
the ratio of WorldxChange's enterprise value to its last quarter annualized
revenues, estimated 2000 revenues as provided by World Access, gross property,
plant and equipment and net property, plant and equipment to those of the
comparable companies and to the reference range, which represents a tighter
range of the ratios as deemed reasonable by Donaldson, Lufkin and Jenrette. For
purposes of this analysis, Donaldson, Lufkin & Jenrette compared the implied
multiples of World Access' consideration to be paid based on the initial
exchange ratio, which results in a higher value for the consideration to be paid
than the maximum exchange ratio. In addition, Donaldson, Lufkin & Jenrette
compared the enterprise value of WorldxChange, based on the initial exchange
ratio, to the implied enterprise values obtained by the above mentioned ratios
of the comparable companies and the reference range and WorldxChange's last
quarter annualized revenues, estimated 2000 revenues as provided by World
Access, gross property, plant and equipment and net property, plant and
equipment. Donaldson, Lufkin & Jenrette's analysis of the comparable companies
yielded the following multiple ranges and implied enterprise values:

     The comparable company analysis showed that the implied multiples of World
Access' consideration, based on the initial exchange ratio, were either within
or lower than the range of multiples implied by the prevailing market prices of
the comparable companies. In addition, the analysis showed that the enterprise
value based on World Access' consideration, based on the initial exchange ratio,
was either within or lower than the range of enterprise values implied by the
multiples of the comparable companies and WorldxChange's last quarter annualized
revenues, estimated 2000 revenues, gross property, plant and equipment and net
property, plant and equipment.

3. ANALYSIS OF SELECTED M&A TRANSACTIONS


     Donaldson, Lufkin & Jenrette reviewed selected mergers and acquisitions
transactions of companies that operate businesses reasonably similar to that of
WorldxChange. In addition, for purposes of this analysis, Donaldson, Lufkin &
Jenrette selected key mergers and acquisitions transactions deemed most relevant
by Donaldson, Lufkin & Jenrette based on the business characteristics of the
acquiror and/or target and the business nature of the transaction. The following
mergers and acquisitions transactions were deemed most relevant by Donaldson,
Lufkin & Jenrette:


     - Viatel, Inc.'s acquisition of Destia Communications, Inc.

     - PRIMUS Telecommunications Group, Incorporated's acquisition of TresCom
       International, Inc.


     In examining these acquisitions, Donaldson, Lufkin & Jenrette calculated
the enterprise value of the acquired company implied by each of these
transactions as a multiple of last quarter annualized revenue and net property,
plant and equipment. In addition, Donaldson, Lufkin & Jenrette calculated the
enterprise values implied by the above mentioned ratios of the selected mergers
and acquisitions transactions and WorldxChange's last quarter annualized revenue
and net property, plant and equipment. Donaldson, Lufkin & Jenrette's analysis
of these comparable acquisitions yielded the following multiple ranges and
implied enterprise values:

</TABLE>



     The analysis of selected mergers and acquisitions transactions showed that
the implied multiples of World Access' consideration, based on the initial
exchange ratio, were, in each case, within or lower than the range of multiples
paid by the selected mergers and acquisitions transactions as well as by the key
mergers and acquisitions transactions. In addition, the analysis of selected
mergers and acquisitions transactions showed that the transaction value of World
Access' consideration, based on the initial exchange ratio, was, in each case,
within or lower than the range of implied transaction values based on the
multiples paid by selected mergers and acquisition transactions, as well as by
the key merger and acquisitions transactions.


4. DISCOUNTED CASH FLOW ANALYSIS


     In addition, Donaldson, Lufkin & Jenrette performed a discounted cash flow
analysis for WorldxChange on a stand-alone basis. The analysis was based upon
financial projections, including synergies, for the five-year period ending
fiscal 2004 as provided by the management of World Access. Donaldson, Lufkin &
Jenrette performed this analysis to estimate the net present value of
WorldxChange's enterprise value and to compare it to the implied enterprise
value based on World Access' consideration. Donaldson, Lufkin & Jenrette
calculated EBITDA for WorldxChange. EBITDA is earnings before interest, taxes,
depreciation and amortization. Donaldson, Lufkin & Jenrette calculated the
terminal value of WorldxChange at the end of the forecast period, by applying a
range of estimated EBITDA multiples selected in Donaldson, Lufkin & Jenrette's
subjective judgment. The terminal value estimates are a hypothetical
approximation of the value of the enterprise's cash flows beyond the end of the
five-year period covered by the management's projections. The management's
projected EBITDA and Donaldson, Lufkin & Jenrette's subjective estimate of the
terminal values based on management's projected EBITDA


                                       104
<PAGE>   118


were then discounted to the present using a range of discount rates selected in
Donaldson, Lufkin & Jenrette's subjective judgment.

<TABLE>
<S>                                                           <C>
Range of EBITDA Multiples...................................   10.0x - 12.0x
Discount rates..............................................   15.0% - 18.3%
Implied Total Enterprise Value..............................  $758.2 - $998.1
WorldxChange Enterprise Value...............................      $924.5
</TABLE>



     The above analysis shows that the implied enterprise value based on World
Access' consideration, based on the initial exchange ratio, of $924.5 million is
near the high range of the implied enterprise values of $758.2 million to $998.1
million obtained by the analysis.



     The summary set forth above does not purport to be a complete description
of the analyses performed by Donaldson, Lufkin & Jenrette but describes the
material elements of the presentation that Donaldson, Lufkin & Jenrette made to
the World Access board on February 11, 2000 in connection with the preparation
of Donaldson, Lufkin & Jenrette's fairness opinion. The preparation of a
fairness opinion involves various determinations as to the most appropriate and
relevant methods of financial analysis and the application of these methods to
the particular circumstances and, therefore, such an opinion is not readily
susceptible to a summary description. Donaldson, Lufkin & Jenrette conducted
each of the analyses in order to provide a different perspective on the
transaction and to add to the total mix of information available. Donaldson,
Lufkin & Jenrette did not form a conclusion as to whether any individual
analysis, considered in isolation, supported or failed to support an opinion as
to fairness from a financial point of view. Rather, in reaching its conclusion,
Donaldson, Lufkin & Jenrette considered the results of the analyses in light of
each other and ultimately reached its opinion based on the results of all
analyses taken as a whole. Donaldson, Lufkin & Jenrette did not place any
particular reliance or weight on any individual analysis, but instead concluded
that its analyses, taken as a whole, supported its determination. Accordingly,
notwithstanding the separate factors summarized above, Donaldson, Lufkin &
Jenrette has indicated to World Access that it believes that its analyses must
be considered as a whole and that selecting portions of its analyses and the
factors considered by it, without considering all analyses and factors, could
create an incomplete view of the evaluation process underlying its opinion. The
analyses Donaldson, Lufkin & Jenrette performed are not necessarily indicative
of actual values or future results, which may be significantly more or less
favorable than suggested by these analyses.



  ENGAGEMENT LETTER



     Under the terms of an engagement letter dated January 18, 2000, World
Access agreed to pay Donaldson, Lufkin & Jenrette a fee of $850,000 at the time
that Donaldson, Lufkin & Jenrette delivered to the World Access board of
directors its opinion, irrespective of the conclusion reached in the opinion,
and to pay Donaldson, Lufkin & Jenrette a fee of $1.5 million, less any amounts
paid pursuant to delivery of the fairness opinion, payable in cash promptly upon
consummation of a business combination between World Access and WorldxChange in
one or a series of transactions, by merger, consolidation, or any other business
combination, by purchase involving all or a substantial amount of the business,
securities or assets of WorldxChange or otherwise. In addition, World Access
agreed to reimburse Donaldson, Lufkin & Jenrette for all of its out-of-pocket
expenses, including the reasonable fees and expenses of counsel incurred by
Donaldson, Lufkin & Jenrette in connection with its engagement, and to indemnify
Donaldson, Lufkin & Jenrette for liabilities and expenses arising out of
Donaldson, Lufkin & Jenrette's engagement, including liabilities under federal
securities laws.



     The terms of the fee arrangement with Donaldson, Lufkin & Jenrette, which
Donaldson, Lufkin & Jenrette and World Access believe are customary in
transactions of this nature, were negotiated at arms-length between World Access
and Donaldson, Lufkin & Jenrette. World Access' board of directors was aware of
such arrangement, including the fact that a significant portion of the aggregate
fee payable to Donaldson, Lufkin & Jenrette is contingent upon consummation of

CONSIDERATION THAT WORLDXCHANGE SHAREHOLDERS WILL RECEIVE IN THE WORLDXCHANGE
MERGER



     Upon completion of the WorldxChange merger, each outstanding share of
WorldxChange common stock will be automatically canceled and converted into the
right to receive 0.6583 shares of World Access common stock. Under the
WorldxChange articles of incorporation, all outstanding shares of WorldxChange
preferred stock voted in favor of the WorldxChange merger will be deemed
automatically converted into shares of WorldxChange common stock immediately
prior to the completion of the WorldxChange merger. Therefore, outstanding
shares of WorldxChange preferred stock voted in favor of the WorldxChange merger
will be entitled to the WorldxChange merger consideration described above on an
as-converted basis. No fractional shares of World Access common stock will be
issued in connection with the WorldxChange merger. Instead, WorldxChange
shareholders will receive cash, without interest, in lieu of any fraction of a
share of World Access common stock to which they would otherwise be entitled
under the WorldxChange merger agreement.



     Upon completion of the WorldxChange merger, each outstanding WorldxChange
stock option or warrant will be automatically converted into an option to
acquire such number of shares of World Access common stock as is equal to the
number of shares of WorldxChange common stock covered under such WorldxChange
stock option or warrant multiplied by 0.6583. The exercise price will be the
exercise price specified in the WorldxChange stock option or warrant divided by
0.6583. Each newly-issued World Access stock option will contain terms which are
substantially similar to the terms governing the original WorldxChange stock
option or warrant.



CLOSING; EFFECTIVE TIME OF THE WORLDXCHANGE MERGER



     The closing of the WorldxChange merger will occur on the second business
day following the satisfaction or waiver of all conditions to the completion of
the WorldxChange merger, or at such other time as World Access and WorldxChange
agree. On the date of the closing of the WorldxChange merger, World Access and
WorldxChange will file a certificate of merger with the Delaware Secretary of
State and an agreement of merger with the California Secretary of State. The
WorldxChange merger will be effective upon the filing of the certificate of
merger and the agreement of merger.



MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE WORLDXCHANGE MERGER



     The following discussion summarizes the material federal income tax
consequences of the WorldxChange merger. Long Aldridge & Norman LLP, as counsel
to World Access, is of the opinion that, except as to matters upon which they
have expressly declined to express an opinion, the following discussion sets
forth the material federal income tax consequences of the WorldxChange merger
under the federal income tax laws in effect as of the date of this joint proxy
statement/prospectus. The following discussion is not a complete analysis of all
aspects of federal income taxation that may be relevant to you as a WorldxChange
shareholder in light of your particular circumstances. For example, it does not
address


                                       106
<PAGE>   120


the federal income tax considerations or the special tax rules that may be
relevant to you if you are one of the following types of holders:



     - an insurance company;



     - a tax-exempt organization;



     - an employee stock ownership plan;



     - a bank;



     - a broker, dealer or financial institution;



     - a holder that holds WorldxChange capital stock as part of a position in a
       "straddle" or as part of a "hedging" or "conversion" transaction for
       federal income tax purposes;



     - a holder that has a "functional currency" other than the United States
       dollar;



     - a holder subject to the alternative minimum tax;



     - a holder that is not a citizen or resident of the United States, or that
       is a foreign corporation, foreign partnership or foreign estate or trust
       as to the United States;



     - a holder who acquired shares of WorldxChange capital stock pursuant to
       the exercise of options or otherwise as compensation or through a
       tax-qualified retirement plan; or



     - a holder of options to acquire shares of WorldxChange capital stock.



     In addition, the discussion does not consider the effect of any foreign,
state, local, or other tax laws, or any tax consequences, such as estate or gift
tax, other than the federal income tax consequences of the WorldxChange merger
that may be applicable to WorldxChange shareholders, or except as expressly
provided below, the consequences of transactions completed before or after the
WorldxChange merger. Further, this discussion assumes that as a WorldxChange
shareholder, you hold your WorldxChange capital stock as a "capital asset"
within the meaning of Section 1221 of the Internal Revenue Code of 1986, as
amended. Generally, a capital asset is property held for investment. This
discussion is based on the Internal Revenue Code and final, temporary and
proposed treasury regulations promulgated under the Internal Revenue Code,
administrative pronouncements and rulings, and judicial decisions as of the date
hereof, all of which are subject to change or differing interpretations at any
time with possible retroactive effect and any such change could affect the
continuing validity of this discussion.



     We have not requested a ruling from the IRS with respect to the federal
income tax consequences of the WorldxChange merger nor is the completion of the
WorldxChange merger conditioned on the receipt by World Access or WorldxChange
of such a ruling or an opinion of tax counsel concerning such tax consequences.
YOU ARE URGED TO CONSULT YOUR OWN TAX ADVISOR AS TO THE SPECIFIC FEDERAL, STATE,
LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES TO YOU OF THE WORLDXCHANGE MERGER.



  The WorldxChange merger



     Long Aldridge & Norman LLP has rendered an opinion to World Access that the
WorldxChange merger will constitute a "reorganization" within the meaning of
Section 368(a) of the Internal Revenue Code. This opinion is subject to the
limitations, qualifications and assumptions referred to herein and in such
opinion. In rendering its opinion as to the status of the WorldxChange merger as
a "reorganization," and in rendering its opinion with respect to the following
discussion, counsel has relied upon, and has assumed the accuracy of
information, factual statements and representations made by World Access and
WorldxChange in this joint proxy statement/prospectus and the WorldxChange
merger agreement. Any inaccuracy or change with respect to such information,
representations or assumptions, or any past or future actions by World Access or
WorldxChange contrary to such information, representations or assumptions could
adversely affect the conclusions reached in such opinion and the discussion set
forth below.


                                       107
<PAGE>   121


     Counsel's opinion neither binds the Internal Revenue Service nor precludes
it or the courts from adopting a contrary position, and no assurance can be
given that contrary positions will not be successfully asserted by the Internal
Revenue Service or adopted by a court if the issues are litigated. The balance
of this discussion is based on the conclusion in the opinion that the
WorldxChange merger will constitute a "reorganization" within the meaning of
Section 368(a) of the Internal Revenue Code.



     WorldxChange has received the opinion of O'Melveny & Myers LLP to the
effect that the WorldxChange merger will be treated for federal income tax
purposes as a reorganization within the meaning of Section 368(a)(1) of the
Internal Revenue Code.



     World Access stockholders will not recognize any gain or loss for federal
income tax purposes solely as a result of the WorldxChange merger.



  Tax considerations for WorldxChange shareholders



     Receipt of World Access stock in the WorldxChange merger.  You will not
recognize gain or loss upon the exchange of your WorldxChange common stock and
preferred stock for World Access common stock and fractional share interests
except for the receipt of cash in lieu of a fractional share of World Access
common stock and the portion of the World Access common stock you received in
payment of accrued and unpaid dividends on your WorldxChange preferred stock
that is treated by the Internal Revenue Service as a dividend distribution to
you, as more fully described below.



     Your tax basis in the shares of World Access common stock you receive in
the exchange will be the same as the tax basis of your shares of WorldxChange
capital stock (and if you hold shares of both common stock and preferred stock
in WorldxChange, by aggregating the tax basis of all such shares) surrendered in
the exchange less any portion of such basis allocable to any fractional share
interest in any share of World Access common stock for which you receive cash.
The holding period of the World Access common stock you receive in the exchange
will include the holding period during which you held your WorldxChange capital
stock.



     Cash for fractional shares.  Based on the current published ruling position
of the Internal Revenue Service, you will recognize gain or loss measured by the
difference between the amount of cash received in lieu of a fractional share
interest in World Access common stock and the portion of the tax basis of your
WorldxChange capital stock allocable to such fractional share interest. Such
gain or loss will be capital gain or loss, provided that you held the
WorldxChange capital stock as a capital asset as of the effective time of the
WorldxChange merger, and will be long-term capital gain if your WorldxChange
capital stock was held for more than one year as of the effective time of the
WorldxChange merger.



     Dividends on escrowed World Access common stock.  Dividends paid to you by
World Access on World Access common stock you receive in the exchange, including
the shares held pursuant to the WorldxChange escrow agreement will be treated as
if you held such shares of World Access common stock directly.



     Return of escrowed shares to World Access to satisfy claims.  Pursuant to
the WorldxChange escrow agreement, if a claim is successfully asserted by World
Access against the escrow fund, the escrow agent will be instructed to return to
World Access that number of shares of World Access common stock with a value in
an amount equal to the claim using the $20.38 share price to value such returned
shares. Any such returned shares would reduce on a pro rata basis the escrowed
shares that could be distributed to WorldxChange shareholders after any
indemnification claims of World Access under the merger agreement are satisfied.
Because the number of shares to be returned to World Access from the escrow
account is based on the initial negotiated value of $20.38 per share of World
Access common stock, you will realize no benefit or detriment from any
appreciation or depreciation of such World Access common stock following the
effective time of the WorldxChange merger. Accordingly, the return of such
shares to World Access in satisfaction of escrow claims will not result in your
recognition of gain or loss and instead, will be treated as a non-taxable
purchase price adjustment as part of the original stock-for-stock exchange. Upon
a return of any such shares to World Access, your tax basis in your pro rata
share of the returned


                                       108
<PAGE>   122

shares will be added to the tax basis of your remaining shares of World Access
common stock received in the exchange.

     Sale of escrowed shares held in the expense fund.  To the extent escrowed
shares of World Access common stock held in the expense fund are sold by the
shareholder representative, you will be required to recognize gain or loss for
federal income tax purposes with respect to your allocable share of the gross
proceeds as if you sold such shares of World Access common stock directly.


     Release of escrowed shares to WorldxChange shareholders.  You will not
recognize any gain or loss or any interest income, as a result of the
distribution to you of any of the World Access common stock held in either the
escrow fund or the expense fund because under both such arrangements described
in the WorldxChange merger agreement, the stock-for-stock exchange takes place
at the effective time of the WorldxChange merger, not later when the escrowed
shares of World Access common stock are released from the applicable escrow
provisions to you as former WorldxChange shareholders.



     World Access common stock received for accrued dividends on WorldxChange
preferred stock.  The law is unclear as to how shares you receive that are or
could be attributed to accrued but undeclared and unpaid dividends, or "dividend
related shares," will be characterized for federal income tax purposes. In at
least two private letter rulings, which cannot be relied upon by other taxpayers
as binding legal precedent, the Internal Revenue Service has taken the position
that common stock issued by an acquiring company in payment of such dividends
would be treated as part of an overall stock-for-stock exchange and would be
tax-free to the recipient shareholders. Moreover, dividends have not been
declared on any of the shares of the WorldxChange preferred stock, will not be
declared as of the effective time of the WorldxChange merger, and, in general,
with certain exceptions not here applicable, shareholders are not taxable on
unpaid dividends that have not been declared. Based upon these principles, you
would not recognize gain or loss on the receipt of the dividend related shares.
Furthermore, the Internal Revenue Service has not taken a position in any
reported case or in any published or private ruling that shares received in
exchange for shares in an otherwise tax-free acquisition should be treated in
part as payment of unpaid dividends. In this case, your tax basis in the
dividend related shares will be the same as your basis in the other shares of
World Access common stock received in the exchange and your holding period for
the dividend related shares will include the holding period during which you
held your WorldxChange preferred stock. Notwithstanding the absence of authority
on point, however, it is possible that the Internal Revenue Service could
attempt to treat the receipt of shares identified with accrued but unpaid
dividends, including the dividend related shares, as the actual or deemed
payment of dividends, and therefore taxable as ordinary income to the extent of
your allocable portion of the accumulated earnings and profits, if any, as
determined for federal income tax purposes, of WorldxChange. If the amount of
such actual or deemed payment exceeds such earnings and profits, then the excess
first will be applied against and reduce your basis in your preferred stock, but
not below zero, and then any excess over such amount will be treated as capital
gain from the sale of such WorldxChange stock and will be long-term capital gain
if your WorldxChange preferred stock was held for more than one year as of the
effective time of the WorldxChange merger. If such actual or deemed payment is
treated as a dividend and you are a corporation, the distribution may qualify
for the "dividends received deduction", and may possibly be subject to the
"extraordinary dividend" provisions of the Internal Revenue Code. Here, your tax
basis in the dividend related shares will be the fair market value of such
shares upon receipt and your holding period will begin upon receipt of such
shares.



     Due to the inherently factual nature of these determinations, coupled with
the lack of Internal Revenue Service or judicial authority as to how your
receipt of the dividend related shares should be characterized for federal
income tax purposes, Long Aldridge & Norman LLP has expressed no opinion with
respect to this matter. World Access intends to take the position that the
dividend related shares should be treated as part of the overall stock-for-stock
exchange. No ruling from the Internal Revenue Service has been sought. Thus, no
assurance can be given to you that the position currently intended to be taken
by World Access described above will be accepted by the Internal Revenue
Service.


                                       109
<PAGE>   123


     Cash received by dissenting WorldxChange shareholders.  If you exercise
appraisal rights, any cash received in connection therewith will be treated as
having been received in redemption of your WorldxChange common stock, provided
the payment is not treated as a dividend payment. If, after such redemption, you
own no World Access stock after giving effect to the constructive ownership
rules of the Internal Revenue Code, then you will recognize gain or loss
measured by the difference between the amount of cash received and the tax basis
of your WorldxChange common stock surrendered, which will be long-term capital
gain or loss if your WorldxChange common stock was held for more than one year
as of the effective time of the WorldxChange merger.



     Reporting requirements.  When you file your federal income tax return for
the taxable year in which the WorldxChange merger occurs, you will be required
to attach a statement to your return which includes certain information required
by the Internal Revenue Service concerning your participation as a WorldxChange
shareholder in the WorldxChange merger. Accordingly, you are urged to consult
with your tax advisor concerning compliance with this requirement and any other
tax reporting requirements.


  Tax considerations for the corporate parties


     World Access, WorldxChange Communications, Inc. formerly known as CTI
Merger Co. and WorldxChange.  No gain or loss will be recognized by World
Access, WorldxChange Communications, Inc., which was formerly known as CTI
Merger Co. and is a subsidiary of World Access, or WorldxChange as a result of
the WorldxChange merger.



     Potential "Excess Parachute Payments."  Under certain circumstances,
acceleration of the vesting of specific WorldxChange options and the making of
certain payments by World Access to WorldxChange employees following the
WorldxChange merger may result in "excess parachute payments" to a "disqualified
individual" within the meaning of Section 280G of the Internal Revenue Code.
World Access will not be entitled to a tax deduction for the amounts determined
to be excess parachute payments, thereby increasing World Access' taxable income
or reducing its taxable loss, if applicable, by the amount of any excess
parachute payments. Excess parachute payments are also subject to a 20% excise
tax payable by the disqualified individual receiving the payment. Because the
calculation of whether such amounts may be determined to be excess parachute
payments cannot be made until the effective time of the WorldxChange merger or
thereafter, no determination can be made at this time whether any amounts will
be determined to be excess parachute payments. Therefore, Long Aldridge & Norman
LLP has expressed no opinion with respect to this matter.



     Limitation on WorldxChange tax attributes.  Under the Internal Revenue
Code, WorldxChange Communications, Inc., which was formerly known as CTI Merger
Co. will succeed to the net operating losses, certain "recognized built-in
losses," capital losses, general business credits, minimum tax credits, excess
foreign tax credits and certain other tax attributes of WorldxChange. Use of
these tax attributes by World Access is subject to specific limitations under
the Internal Revenue Code and certain provisions of the treasury regulations
governing the filing of a consolidated federal income tax return, such as the
"separate return limitation year" rules. After an ownership change, the amount
of the loss corporation's taxable income for a post-ownership change year that
may be offset by the loss corporation's net operating losses arising before the
ownership change is annually limited to an amount referred to as the "Section
382 limitation." The Section 382 limitation generally equals the product of (i)
the fair market value of the loss corporation's stock immediately before the
ownership change, multiplied by (ii) the federal long-term, tax-exempt rate
published monthly by the Internal Revenue Service (5.53% for August 2000).



     WorldxChange and its domestic subsidiaries are members of a "consolidated
group" which files a consolidated federal income tax return. The WorldxChange
consolidated group, with WorldxChange Communications, Inc., which was formerly
known as CTI Merger Co. as WorldxChange's corporate successor will constitute a
"loss subgroup" which will undergo a Section 382 ownership change upon the
completion of the WorldxChange merger. Utilization of any such loss subgroup's
net operating loss carryover, which we refer to as the "pre-change WorldxChange
loss subgroup net operating losses," against


                                       110
<PAGE>   124


future World Access consolidated federal taxable income will be subject to an
annual loss subgroup Section 382 limitation.



     An additional limitation may apply under which the pre-change WorldxChange
loss subgroup net operating losses can only be used to the extent of the
"qualifying separate return limitation year subgroup" members' aggregate,
cumulative contribution to World Access consolidated taxable income or the
"separate return limitation year limitation." Because the WorldxChange loss
subgroup and its separate return limitation year net operating loss subgroup
should be treated as co-extensive, and the Section 382 ownership change and
separate return limitation year event will occur at the same time, the separate
return limitation year limitation should be eliminated with respect to the
WorldxChange loss subgroup net operating losses.



     Limitation on World Access tax attributes.  World Access and its domestic
subsidiaries are members of a "consolidated group" which files a consolidated
federal income tax return. For its taxable year ended December 31, 1999, the
World Access consolidated group incurred a consolidated net operating loss, and
has a consolidated net operating loss carryover. As such, it constitutes a "loss
group." World Access believes that the World Access loss group may have already
incurred a Section 382 ownership change in either or both of its 1998 and 1999
taxable years. Thus, the World Access loss group's ability to utilize its own
consolidated net operating loss carryover as of December 31, 1999 against its
future consolidated federal taxable income may already be subject to an annual
loss group Section 382 limitation.



     If the completion of either or both the WorldxChange merger and the STAR
merger does result in an ownership change for the World Access loss group, the
amount of such annual loss group Section 382 limitation will depend in part, on
future values which cannot be predicted at this time. In the case of successive
ownership changes, the applicable pre-ownership change World Access loss group
or member's net operating losses will be subject to the lowest amount of Section
382 limitation which results from any of such Section 382 ownership changes. If
instead, consummation of either or both the WorldxChange merger and the STAR
merger does not result in an ownership change for the World Access loss group,
then any existing annual loss group Section 382 limitation for World Access will
simply continue to apply.



EXCHANGE OF WORLDXCHANGE STOCK CERTIFICATES FOR WORLD ACCESS STOCK CERTIFICATES



     When the WorldxChange merger is completed, World Access' exchange agent
will mail to WorldxChange shareholders a letter of transmittal and instructions
for use in surrendering WorldxChange stock certificates in exchange for World
Access stock certificates. When WorldxChange shareholders deliver their
WorldxChange stock certificates to the exchange agent along with an executed
letter of transmittal and any other required documents, their WorldxChange stock
certificates will be canceled, and WorldxChange shareholders will receive World
Access stock certificates representing the number of full shares of World Access
common stock to which the WorldxChange shareholder is entitled under the
WorldxChange merger agreement. WorldxChange shareholders will receive payment in
cash in lieu of any fractional shares of World Access common stock which would
have been otherwise issuable in the WorldxChange merger.



     YOU SHOULD NOT SUBMIT YOUR WORLDXCHANGE STOCK CERTIFICATES FOR EXCHANGE
UNLESS AND UNTIL YOU RECEIVE THE TRANSMITTAL INSTRUCTIONS AND A FORM OF LETTER
OF TRANSMITTAL FROM THE EXCHANGE AGENT.


                                       111

RESTRICTIONS ON SALES OF SHARES BY AFFILIATES OF WORLD ACCESS AND WORLDXCHANGE



     The shares of World Access common stock to be issued in the WorldxChange
merger will be registered under the Securities Act of 1933. These shares will be
freely transferable under the Securities Act of 1933, except for shares of World
Access common stock issued to any person who is an affiliate of either of World
Access or WorldxChange. Persons who may be deemed to be affiliates include
individuals or entities that control, are controlled by, or are under common
control with either of World Access or WorldxChange and may include some of
their respective officers and directors, as well as their respective principal
stockholders. Affiliates may not sell their shares of World Access common stock
acquired in the WorldxChange merger except pursuant to:



     - an effective registration statement under the Securities Act of 1933
       covering the resale of those shares;



     - Rule 145 under the Securities Act of 1933; or



     - any other applicable exemption under the Securities Act of 1933.



ACCOUNTING TREATMENT OF THE WORLDXCHANGE MERGER



     We intend to account for the WorldxChange merger as a purchase for
financial reporting and accounting purposes, under United States generally
accepted accounting principles. After the WorldxChange merger, the results of
operations of World Access and WorldxChange will be included in the consolidated
financial statements of World Access. The purchase price will be allocated based
on the fair values of the assets acquired and the liabilities assumed. Any
excess of cost over fair value of the net tangible assets of WorldxChange
acquired will be recorded as goodwill and other intangible assets and will be
amortized by charges to operations under United States generally accepted
accounting principles. These allocations will be made based upon valuations and
other studies that have not yet been finalized.



REGULATORY FILINGS AND APPROVALS REQUIRED TO COMPLETE THE WORLDXCHANGE MERGER



     The WorldxChange merger is subject to the requirements of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, which prevents
transactions from being completed until required information and materials are
furnished to the Antitrust Division of the Department of Justice and the Federal
Trade Commission and the appropriate waiting periods end or expire. World
Access, WorldxChange and related parties have filed the required information and
materials with the Antitrust Division of the Department of Justice and the
Federal Trade Commission. The Department of Justice and Federal Trade Commission
granted an early termination of the waiting period, effective April 6, 2000. No
further action under the Hart-Scott-Rodino Act is required, as long as the
WorldxChange merger is completed prior to April 6, 2001.



     The Antitrust Division of the Department of Justice or the Federal Trade
Commission may challenge the WorldxChange merger on antitrust grounds either
before or after expiration of the waiting period. Accordingly, at any time
before or after the completion of the WorldxChange merger, either the Antitrust
Division of the Department of Justice or the Federal Trade Commission could take
action under the antitrust laws. Certain other persons could take action under
the antitrust laws, including seeking to enjoin the WorldxChange merger.
Additionally, at any time before or after the completion of the WorldxChange
merger, notwithstanding that the applicable waiting period expired or ended, any
state could take action under the antitrust laws. There can be no assurance that
a challenge to the WorldxChange merger under the antitrust laws will not be made
or that, if a challenge is made, it would not be successful.



     The WorldxChange merger also requires notification in certain European
countries.



     Under the German Competition Act, the German Cartel Office must be notified
of the WorldxChange merger, and the WorldxChange merger cannot be completed
until approved by the German Cartel Office or a one month waiting period has
expired. The waiting period starts from the date that the notification is
considered by the German Cartel Office to be complete. During the initial one
month


                                       112
<PAGE>   126


waiting period, the German Cartel Office may decide to open a further
investigation of the transaction. If a further investigation is instituted, the
WorldxChange merger may not be completed until a further three month period has
expired or the WorldxChange merger has been cleared. At any time during the
period, the German Cartel Office may act to block the WorldxChange merger or
impose conditions upon its completion. There can be no assurance that a
challenge to the WorldxChange merger on competition law grounds will not be made
or that, if such a challenge is made, it would not be successful in Germany.



     Following the completion of the WorldxChange merger, an information filing
must be made in Denmark with the national competition authority. In addition,
the WorldxChange merger is also subject to review and clearance by the foreign
investment review boards of Australia and New Zealand.



     The WorldxChange merger is subject to state and federal telecommunications
regulatory approvals. All but two of the state regulatory agencies and the
Federal Communications Commission require prior notice or approval of the
WorldxChange merger. Applications or notices, as required, requesting either
approval or providing notification of the WorldxChange merger have been filed on
behalf of World Access and WorldxChange in 48 states and at the Federal
Communications Commission. The governing legal standard for approval varies from
state to state, but approval of the WorldxChange merger generally requires a
showing that it is consistent with the public interest. The Federal
Communications Commissions has approved the WorldxChange merger.



     Except for approvals by state and federal authorities having jurisdiction
over telecommunications activities conducted by World Access and WorldxChange,
World Access and WorldxChange are not aware of any other material governmental
or regulatory approval required for completion of the WorldxChange merger, other
than the effectiveness of the registration statement of which this joint proxy
statement/prospectus is a part, and compliance with applicable corporate laws
of Delaware and California.



RIGHTS OF DISSENTING WORLDXCHANGE SHAREHOLDERS



     The following provides a summary of the statutory procedure a dissenting
WorldxChange shareholder must follow in order to exercise dissenters' rights
under Chapter 13 of the California General Corporation Law. This summary is
qualified in its entirety by reference to the full text of Chapter 13 of the
California law. A copy of Chapter 13 of the California law is attached as Annex
I to this joint proxy statement/prospectus and is incorporated by reference
into this document. Failure to comply with the procedures set forth in
California law will result in the loss or waiver of dissenters' rights.
Therefore, this discussion and Chapter 13 of the California law should be
reviewed carefully by any WorldxChange shareholder who wishes to exercise
statutory dissenters' rights or who wishes to preserve the right to do so.



     If the WorldxChange merger is completed, each WorldxChange shareholder
owning shares on the date for the determination of shareholders entitled to vote
on or consent to the WorldxChange merger that does not vote their shares in
favor of the WorldxChange merger and complies with the provisions and procedures
of Chapter 13 of the California law, will be entitled to require WorldxChange to
purchase for cash at their fair market value the WorldxChange shares owned by
such shareholder.



     The fair market value of the WorldxChange shares will be determined as of
the day before the first announcement of the terms of the proposed WorldxChange
merger, excluding any appreciation or depreciation resulting from the merger but
adjusted for any stock split, reverse stock split or share dividend that becomes
effective after the announcement. A failure to vote against the WorldxChange
merger will not constitute a waiver of dissenters' rights set forth in Chapter
13 of the California law. Any WorldxChange shares as to which dissenters' rights
are exercised will not be converted into the right to receive shares of World
Access common stock in the merger.



     The merger agreement provides that WorldxChange will not be the surviving
corporation in the WorldxChange merger. Under California law, the surviving
corporation will assume WorldxChange's obligations under Chapter 13 of the
California law.

     To qualify as a dissenting share under California law, shares of
WorldxChange stock must satisfy each of the following requirements:



     - the shares of WorldxChange stock must have been outstanding on the record
       date;



     - the shares of WorldxChange stock must not have been voted in favor of the
       WorldxChange merger;



     - the holder of such shares of WorldxChange stock must make a written
       demand that WorldxChange repurchase such shares of WorldxChange stock at
       fair market value; and



     - the holder of such shares of WorldxChange stock must submit share
       certificates for endorsement.



     WorldxChange is required within 10 days after the date of the approval of
the merger by the required WorldxChange shareholder vote or consent to mail a
notice of the approval of the merger to each shareholder who has not voted to
approve and adopt the WorldxChange merger, together with:



     - a copy of Sections 1300 through 1304 of Chapter 13 of the California law;



     - a statement of the price determined by WorldxChange to represent the fair
       market value of the dissenting WorldxChange shares; and



     - a brief description of the procedure to be followed if the shareholder
       desires to exercise dissenters' rights. The statement of price by
       WorldxChange constitutes an offer by WorldxChange to purchase all
       properly dissenting shares at the stated amount.



     In order to exercise dissenters rights, shareholders must send a written
demand to WorldxChange that WorldxChange repurchase their dissenting shares.
WorldxChange must receive this demand within 30 days after the date on which
notice of the approval of the WorldxChange merger by the outstanding shares of
WorldxChange stock is mailed to dissenting shareholders. The demand must state
the number and class of shares held of record that the shareholder demands that
WorldxChange purchase, and a statement of what the dissenting shareholder claims
to be the fair market value of the dissenting shares as of the day before the
announcement of the proposed merger. The statement of fair market value in this
demand by the dissenting shareholder constitutes an offer by the shareholder to
sell the shares at this price to WorldxChange.



     In addition, within 30 days after the date on which notice of the approval
by the outstanding shares was mailed to shareholders, the dissenting shareholder
must also submit to WorldxChange at its principal office or the office of its
transfer agent share certificates representing any dissenting shares that the
dissenting shareholder demands that WorldxChange purchase, so that the
dissenting shares may either be stamped or endorsed with the statement that the
shares are dissenting shares or may be exchanged for certificates of appropriate
denomination so stamped or endorsed.



     If the dissenting shareholder and WorldxChange agree that the shares
qualify as dissenting shares and agree upon the price of the shares, the
dissenting shareholder is entitled to the agreed upon price plus the legal rate
of interest on judgments from the date of such agreement. This amount is to be
paid to the dissenting shareholder within the later of 30 days after the date of
such agreement or 30 days after any statutory or contractual conditions to the
closing of the WorldxChange merger are satisfied or waived, subject to surrender
by the dissenting shareholder of his, her or its certificates representing the
dissenting shares to WorldxChange unless provided otherwise by agreement. Any
agreement between WorldxChange and a shareholder fixing the fair market value of
any dissenting shares will be filed with the secretary of WorldxChange.



     If the dissenting shareholder and WorldxChange fail to agree upon the fair
market value of the dissenting shares or whether the shares qualify as
dissenting shares, the dissenting shareholder may file a complaint in California
superior court of the proper county within six months after the date on which
notice of the approval of the WorldxChange merger is mailed to shareholders
requesting that the court determine the fair market value of the dissenting
shares and, if applicable, whether the shares qualify as dissenting shares.


                                       114
<PAGE>   128


     The costs and expenses of the action, including reasonable compensation to
the appraisers, will be fixed and assessed or apportioned as the court considers
equitable. However, if the appraisal exceeds the price offered by WorldxChange,
then WorldxChange would be required to pay the costs, including, in the
discretion of the court, attorneys' fees, fees of expert witnesses and interest
at a legal rate on the judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is 125 percent of
the price offered by WorldxChange.



     Under the provisions of Chapter 5 of the California law and Section 1306 of
the California law, a California corporation is legally prohibited from
purchasing shares of stock through the payment of cash or other property, even
if all dissenters' rights conditions are fulfilled, unless the corporation
satisfies certain financial conditions. Due to these legal restrictions, neither
WorldxChange nor the surviving corporation in the WorldxChange merger may be
legally able to repurchase all or any dissenting shares of the dissenting
shareholders for cash.



     To the extent that WorldxChange is prohibited from making cash payments to
holders of dissenting shares who exercise and perfect their dissenters' rights
of their fair market value, unpaid dissenting shareholders will become creditors
of WorldxChange for the unpaid amount plus interest at the legal rate on
judgments until the date of payment. The rights of unpaid dissenting
shareholders, however, will be subordinate to the rights of all other creditors
of WorldxChange in any liquidation proceeding, with the unpaid debt to be
payable when permissible under the provisions of Chapter 5.



     If any shareholder who demands the purchase of his, her or its shares under
Chapter 13 of the California law fails to perfect, or effectively withdraws or
loses his, her or its right to such purchase, the shares of that holder will be
converted into a right to receive the applicable merger consideration in
accordance with the WorldxChange merger agreement.



     Dissenting shares lose their status as dissenting shares if:



     - the WorldxChange merger is abandoned, in which case WorldxChange must pay
       on demand to any dissenting shareholder who has initiated proceedings in
       good faith under Chapter 13 of the California law all necessary expenses
       incurred in these proceedings and reasonable attorney's fees;



     - the shares are transferred prior to their submission for the required
       endorsement or are surrendered for conversion into shares of another
       class in accordance with the amended and restated articles of
       incorporation of WorldxChange;



     - the dissenting shareholder and WorldxChange do not agree upon the status
       of the shares as dissenting shares or do not agree on the purchase price
       of the shares, but neither WorldxChange nor the shareholder files a
       complaint or intervenes in a pending action within six months after
       mailing the notice of approval of the WorldxChange merger; or



     - with WorldxChange's consent, the shareholder delivers to WorldxChange a
       written withdrawal of such shareholder's demand for purchase of his, her
       or its shares.



     Except as expressly limited by provisions of California law pertaining to
dissenters' rights, holders of dissenting shares continue to have all of the
rights and privileges incident to their shares until the fair market value of
their shares is agreed upon or determined. A dissenting shareholder may not
withdraw the demand for payment of the fair market value of dissenting shares
unless WorldxChange consents to the request for withdrawal.



     FAILURE TO FOLLOW THE STEPS REQUIRED BY CHAPTER 13 OF THE CALIFORNIA
GENERAL CORPORATION LAW FOR PERFECTING DISSENTERS' RIGHTS MAY RESULT IN THE LOSS
OF SUCH RIGHTS (IN WHICH EVENT A SHAREHOLDER WILL BE ENTITLED TO RECEIVE THE
APPLICABLE MERGER CONSIDERATION IN EXCHANGE FOR THOSE DISSENTING SHARES IN
ACCORDANCE WITH THE WORLDXCHANGE MERGER AGREEMENT). BECAUSE OF THE COMPLEXITY OF
THE PROVISIONS OF CHAPTER 13, WORLDXCHANGE SHAREHOLDERS WHO ARE CONSIDERING
OBJECTING TO THE WORLDXCHANGE MERGER SHOULD CONSULT THEIR OWN LEGAL ADVISORS.

INTERESTS OF WORLDXCHANGE'S DIRECTORS, OFFICERS AND SHAREHOLDERS IN THE
WORLDXCHANGE MERGER



     Certain WorldxChange officers, directors and shareholders have interests in
the merger that are different from or in addition to those of the other
shareholders of WorldxChange, as follows:



     - World Access is obligated under the WorldxChange merger agreement to
       cause Walter Anderson, WorldxChange's Chairman of the board, or another
       person designated by Mr. Anderson, to be elected to the World Access
       board.



     - In the WorldxChange merger, the WorldxChange shares beneficially owned by
       WorldxChange executive officers (including common stock issuable upon
       conversion of the preferred stock owned beneficially by directors Walter
       Anderson and Tom Cirrito) and directors as of August 1, 2000 will be
       converted into a total of 25,144,433 shares of World Access with a total
       value of approximately $226,299,897, assuming a per share value of the
       World Access common stock of $9.00. In addition, these officers and
       directors held options and warrants that were exercisable within 60 days
       of August 1, 2000 to purchase a total of 828,950 shares of WorldxChange
       common stock at exercise prices ranging between $.67 and $11.00. To the
       extent these options are not exercised before the merger, these options
       will carry over and be exercisable for World Access common stock, with
       the exercise price and number of shares applicable to each option
       adjusted based on the exchange ratio.



     - Roger Abbott, WorldxChange's Chief Executive Officer and a director, and
       Edward Soren, WorldxChange's Executive Vice President and a director,
       have agreed with World Access not to sell shares of World Access common
       stock received by them in the WorldxChange merger for a period of six
       months after the WorldxChange merger is completed. However, World Access
       has agreed to permit Roger Abbott to sell up to $30 million worth of the
       World Access shares he receives in the WorldxChange merger beginning
       immediately after the WorldxChange merger is completed. In addition,
       World Access has agreed to allow Mr. Soren to sell up to 750,000 of the
       World Access shares received by him in the merger beginning immediately
       after the WorldxChange merger is completed.



     - Under Mr. Abbott's employment agreement with WorldxChange, if Mr.
       Abbott's employment with WorldxChange is terminated other than for cause,
       death or disability following the completion of the WorldxChange merger,
       Mr. Abbott will be entitled all earned but unpaid salary and bonus
       through the date of termination, plus a lump sum cash payment equal to
       $50,000 times the number of months then remaining until July 31, 2002,
       plus the cost for Mr. Abbott to maintain through July 31, 2002 the
       insurance and other benefits enjoyed by Mr. Abbott at the time of his
       termination.



     - Under his employment agreement with WorldxChange, Patrick Aelvoet,
       WorldxChange's Chief Financial Officer, will be entitled to a $25,000
       bonus upon completion of the WorldxChange merger. He is also entitled to
       a $50,000 severance payment if, after the WorldxChange merger, his
       employment with WorldxChange is terminated without cause and without at
       least 90 days' advance notice. In addition, if Mr. Aelvoet's employment
       with WorldxChange is involuntarily terminated within 12 months after the
       WorldxChange merger, all of his unvested options to purchase World Access
       common stock will become immediately fully vested and remain so until the
       earlier of one year following such termination or ten years from the
       applicable grant date. Mr. Aelvoet has options to purchase a total of
       150,000 shares of WorldxChange common stock at exercise prices ranging
       from $9.00 to $11.00 per share. As of August 1, 2000, 56,250 of these
       options were vested and 93,750 options were unvested. Unless their
       vesting is accelerated as described above, these unvested options will
       vest at varying rates each calendar quarter.



     - Under his employment agreement with WorldxChange, if the employment of
       Eric Lipoff, WorldxChange's Vice President and General Counsel, is
       involuntarily terminated following the WorldxChange merger, he will be
       entitled to receive all earned but unpaid salary and bonuses through the
       date of such termination, plus a lump sum cash payment equal to $16,666
       times the number of months then remaining until December 31, 2002, plus
       the cost for Mr. Lipoff to


                                       116
<PAGE>   130


       maintain through December 31, 2002 the health insurance and other
       benefits in effect at the time of such termination. In addition, if Mr.
       Lipoff's employment is terminated without cause after the WorldxChange
       merger and on or prior to December 31, 2002, all of Mr. Lipoff's
       currently unvested options to purchase a total of 150,000 shares of
       WorldxChange common stock at $10.00 per share, would become immediately
       fully vested.



     - WorldxChange directors Sen. Paul Laxalt and Dann Angeloff each have
       options to purchase 57,500 shares of WorldxChange common stock at $10.00
       per share. As of August 1, 2000, a total of 52,292 of these options were
       vested. Following the WorldxChange merger, all of these unvested options
       will immediately fully vest and remain exercisable for one year following
       the completion of the merger.

                DESCRIPTION OF THE WORLDXCHANGE MERGER AGREEMENT



     World Access and WorldxChange entered into the original WorldxChange merger
agreement on February 11, 2000. On May 23, 2000, the parties amended the
original WorldxChange merger agreement to delete the provisions therein relating
to the possible payment by World Access to the WorldxChange shareholders of
contingent shares after the completion of the WorldxChange merger and to make
the necessary conforming changes. On August 1, 2000, World Access and
WorldxChange again amended the WorldxChange merger agreement to reflect the fact
that the parties entered into a management services agreement. The original
WorldxChange merger agreement, as amended, is referred to in this joint proxy
statement/prospectus as the WorldxChange merger agreement. This is only a
summary of the WorldxChange merger agreement and may not contain all of the
information that is important to you. World Access and WorldxChange urge you to
read the WorldxChange merger agreement carefully and in its entirety.



DESCRIPTION OF THE WORLDXCHANGE MERGER CONSIDERATION



     After the completion of the WorldxChange merger, WorldxChange will be a
wholly-owned subsidiary of World Access and each outstanding share of
WorldxChange common stock held by WorldxChange or a subsidiary of WorldxChange
will be cancelled and will no longer be outstanding. Each share of WorldxChange
common stock not held by WorldxChange or a subsidiary of WorldxChange will be
converted into the right to receive 0.6583 shares of World Access common stock.
No fractional shares will be issued. Instead, WorldxChange shareholders will
receive cash based on the market price of World Access common stock.



REPRESENTATIONS AND WARRANTIES CONTAINED IN THE WORLDXCHANGE MERGER AGREEMENT



     World Access and WorldxChange each made representations and warranties in
the WorldxChange merger agreement regarding aspects of their respective
businesses, financial condition, structure and other facts pertinent to the
WorldxChange merger, including:



     - corporate existence, organization, standing, authority and capitalization



     - financial statements;



     - compliance with applicable laws and required licenses and permits;



     - absence of conflicts between each party's obligations under the
       WorldxChange merger agreement and its charter, bylaws, and material
       contracts, and applicable law;


                                       119
<PAGE>   133


     - absence of pending or threatened suits, actions or other proceedings not
       already disclosed in the WorldxChange merger agreement;



     - the filing of tax returns and payment of taxes;



     - consents and regulatory approvals required to complete the WorldxChange
       merger; and



     - required approvals by the respective boards of directors and
       stockholders.



WORLDXCHANGE'S CONDUCT OF BUSINESS BEFORE COMPLETION OF THE WORLDXCHANGE MERGER



     WorldxChange has agreed that until the completion of the WorldxChange
merger, it will conduct its business in the ordinary course and substantially in
accordance with past practice.



     WorldxChange also agreed that until the completion of the WorldxChange
merger, it would conduct business in compliance with specific restrictions
relating to:



     - the issuance, redemption, reclassification, combination or split of any
       of its capital stock;


     - employees and employee benefits and remuneration;


     - the issuance of dividends or other distributions on its capital stock;



     - the modification of its certificate of incorporation or bylaws;


     - the acquisition of assets or other entities;


     - the sale of assets;



     - the incurrence of new indebtedness;


     - capital expenditures and other investments;


     - entering into contracts that would restrict World Access from engaging in
       business in certain geographic areas after the completion of the
       WorldxChange merger;



     - changing its accounting policies and procedures; and


     - the settlement of litigation.


NO OTHER NEGOTIATIONS INVOLVING WORLDXCHANGE



     Until the WorldxChange merger is completed, WorldxChange has agreed that it
will not permit any of its agents and representatives to, directly or indirectly
take any of the following actions without World Access' written consent:



     - solicit any inquiries regarding an acquisition proposal;



     - participate in any discussions or negotiations regarding an acquisition
       proposal; or



     - disclose any confidential information with respect to an acquisition
       proposal.



     WorldxChange also agreed that it would cause its agents and representatives
to, immediately discontinue any discussions or negotiations regarding an
acquisition proposal in effect on February 11, 2000.



TREATMENT OF WORLDXCHANGE STOCK OPTIONS AND WARRANTS



     After completion of the WorldxChange merger, each outstanding WorldxChange
stock option or warrant will be automatically converted into an option to
purchase the number of shares of World Access common stock as is equal to the
number of shares of WorldxChange common stock covered under the WorldxChange
stock option or warrant multiplied by 0.6583 at a per share price equal to the
exercise price of the WorldxChange option or warrant divided by 0.6583. Each
newly issued World Access stock option will contain terms substantially similar
to the terms of the original STAR stock option or warrant.


                                       120
<PAGE>   134

BOARD OF DIRECTORS AND OFFICERS OF WORLD ACCESS


     World Access and WorldxChange agreed that, immediately following the
completion of the WorldxChange merger, World Access will elect a WorldxChange
designee to the World Access board of directors. The WorldxChange designee will
be Walter Anderson, or a person designated by Gold & Appel Transfer S.A. and
acceptable to World Access. Gold & Appel S.A. is a shareholder of WorldxChange.



CONDITIONS TO COMPLETION OF THE WORLDXCHANGE MERGER



     Each party's obligations to complete the WorldxChange merger is subject to
the satisfaction or waiver of each of the following material conditions:



     - the WorldxChange merger agreement and the WorldxChange merger must be
       approved by the required vote of the stockholders of World Access and
       WorldxChange;



     - this joint proxy statement/prospectus must have been declared effective
       by the Securities and Exchange Commission, and must not be subject to a
       stop order suspending the effectiveness of this joint proxy
       statement/prospectus; and



     - World Access and WorldxChange must have entered into an escrow agreement
       governing the terms and conditions of the holding and release of the
       shares of World Access common stock issued in the WorldxChange merger.



     - each of the representations and warranties of the other party must be
       true and correct as of February 11, 2000 and as of the date the
       WorldxChange merger is completed except where any failure to be true and
       correct results from any act of World Access performed under the
       management services agreement between World Access and WorldxChange or
       would not have a material adverse effect on the other party;



     - each party must perform or comply with its agreements and covenants
       required by the WorldxChange merger agreement, except that WorldxChange
       will be deemed to have satisfied this condition even if it has not
       performed or complied with its agreements and covenants if the failure to
       do so is due to WorldxChange's performance of its obligations under the
       management services agreement between World Access and WorldxChange; and



     - each party must obtain all consents and approvals required by the
       WorldxChange merger, except where the failure to obtain any such consent
       or approval would not have a material adverse effect on the other party
       or if such failure results from acts performed by World Access under the
       management services agreement between World Access and WorldxChange;



     Additionally, World Access' obligations to complete the WorldxChange merger
are subject to the satisfaction or waiver of the following conditions before
completion of the WorldxChange merger:



     - WorldxChange must have complied with all procedures and requirements
       applicable to it under the dissenters' rights chapter of the California
       General Corporation Law, the period for exercising dissenters' rights
       under the California General Corporation Law must have expired and fewer
       than 1% of the shares of WorldxChange capital stock shall have exercised
       dissenters' rights with respect to the WorldxChange merger; and



     - all shares of WorldxChange preferred stock shall have been voted in favor
       of the WorldxChange merger agreement, and such shares shall have been
       deemed converted into not more than 8,282,829 shares of WorldxChange
       common stock.

TERMINATION OF THE WORLDXCHANGE MERGER AGREEMENT



     The WorldxChange merger agreement may be terminated at any time prior to
completion of the WorldxChange merger by either party for any of the following
reasons:



     - by mutual written consent;



     - if the other party fails to comply in any material respects with any of
       its covenants or agreements in the WorldxChange merger agreement and
       fails to cure the failure within 30 days after receipt of notice of
       breach. However, the non-breaching party may not terminate the
       WorldxChange merger agreement if the breaching party is using reasonable
       efforts to cure the breach, and World Access may not terminate the
       WorldxChange merger agreement if WorldxChange's breach is because of acts
       of World Access performed under the management services agreement between
       World Access and WorldxChange;



     - if the other party has breached any of its representations or warranties,
       which breach has not been cured within 30 days after receipt of written
       notice of the breach. However, the non-breaching party may not terminate
       the WorldxChange merger agreement as long as the breaching party is using
       reasonable efforts to cure the breach, and World Access may not terminate
       the WorldxChange merger agreement if WorldxChange's breach is because of
       acts of World Access performed under the management services agreement
       between World Access and WorldxChange;



     - if the WorldxChange merger is not completed before December 31, 2000,
       except that the right to terminate the WorldxChange merger agreement is
       not available to the party whose action or failure to act has been the
       cause of or resulted in the failure of the WorldxChange merger to occur
       on or before December 31, 2000; or



     - if the WorldxChange merger agreement fails to receive the requisite vote
       for approval by the stockholders of World Access or WorldxChange, in each
       case upon the taking of such vote.



EXTENSION, WAIVER AND AMENDMENT OF THE WORLDXCHANGE MERGER AGREEMENT



     The WorldxChange merger agreement may be amended by World Access and
WorldxChange at any time before completion of the WorldxChange merger. However,
following stockholder approval, no amendment may be made that requires further
approval by the stockholders. World Access and WorldxChange may extend the time
for the performance of any of the obligations or other acts of the other party
under the WorldxChange merger agreement, waive any inaccuracies of the other
party's representations and warranties and waive compliance with any of the
agreements or conditions of the other party contained in the WorldxChange merger
agreement.


POST-CLOSING INDEMNIFICATION


     After the completion of the WorldxChange merger, World Access will be
entitled to indemnification from and against any and all losses incurred by
World Access, its successors or assigns, and their respective officers,
employees, consultants and agents as a result of any of the following:



     - a breach of any representation or warranty of WorldxChange in the
       WorldxChange merger agreement;



     - a breach of any representation or warranty of WorldxChange in the
       certificate to be provided by WorldxChange at the closing with respect to
       the truth, accuracy and fulfillment of representations, warranties and
       covenants of WorldxChange;



     - a breach prior to the completion of the WorldxChange merger of any
       covenant or agreement of WorldxChange contained in the WorldxChange
       merger agreement; or



     - the imposition of the suspended $17.6 million dollar fine, or other
       monetary penalty, imposed in connection with or related to a matter
       involving WorldxChange before the California Public Utilities Commission.
       However, World Access will only be entitled to indemnification if the

                                       122
<PAGE>   136


       imposition arises out of wrongful acts or omissions of WorldxChange which
       occur after the effective date of the order related to such matter and
       before the completion of the WorldxChange merger.



     WorldxChange will not have to indemnify World Access for losses incurred
because of acts of World Access performed under the management services
agreement between World Access and WorldxChange. All claims for indemnification
must be asserted no later than one year following the completion of the
WorldxChange merger. No claim may be made, except in limited circumstances,
until the amount of each loss in excess of $150,000 exceeds $3.0 million in the
aggregate, at which time World Access may claim indemnification for the amount
of losses, in each case net of $150,000, in excess of $3.0 million.



     Upon approval of the WorldxChange merger agreement and the transactions
contemplated by the WorldxChange merger agreement by the WorldxChange
shareholders, Edward S. Soren, a shareholder of WorldxChange, will serve as the
attorney-in-fact and agent of the WorldxChange shareholders with authority to
take any actions permitted to be taken by the WorldxChange shareholders under
the WorldxChange merger agreement and the escrow agreement, including those
related to indemnification.



           WORLDXCHANGE SERVICES, VOTING AND PARTICIPATION AGREEMENTS



     This section of the joint proxy statement/prospectus describes agreements
related to the WorldxChange merger agreement, including the World Access
stockholders' voting and stock transfer restriction agreement, the WorldxChange
shareholders' voting and stock transfer restriction agreements, the escrow
agreement, the World Access -- WorldxChange services agreement and the Foothill
Capital Corporation participation agreement. While World Access and WorldxChange
believe that these descriptions cover the material terms of these agreements,
these summaries may not contain all of the information that is important to you.


WORLD ACCESS VOTING AGREEMENT


     On February 11, 2000, WorldxChange and certain World Access stockholders,
including Armstrong International Telecommunications, Inc., WorldCom Network
Services, Inc., The 1818 Fund III, L.P., John D. Phillips, Walter J. Burmeister,
W. Tod Chmar Geocapital V, L.P., Geocapital Advisors, L.P., Geocapital Investors
V, L.P., Gilbert Global Equity Partners, L.P., Gilbert Global Equity Partners
(Bermuda), L.P. and Resurgens Partners, LLC, entered into a voting and stock
transfer restriction agreement, pursuant to which each World Access stockholder
agreed to vote all of its shares of World Access capital stock (whether owned
beneficially or of record), as well as any other shares of World Access capital
stock such World Access stockholder acquires prior to the completion of the
WorldxChange merger, in favor of the WorldxChange merger and the adoption and
approval of the WorldxChange merger agreement. Each World Access stockholder
also agreed to vote against any action or agreement that would result in a
material breach of any covenant, representation or warranty of World Access
contained in the WorldxChange merger agreement. Further, each World Access
stockholder agreed not to (except in limited circumstances) sell, hypothecate,
transfer, pledge, encumber, assign or otherwise dispose of any of its shares of
World Access capital stock prior to the termination of the voting and stock
transfer restriction agreement. The voting and stock transfer restriction
agreement terminates upon the first to occur of:



     - the termination of the WorldxChange merger agreement in accordance with
       the termination provisions of the WorldxChange merger agreement,



     - the completion of the WorldxChange merger and



     - October 31, 2000.



     As of the World Access record date, the World Access stockholders that
entered into the voting and stock transfer restriction agreement owned shares of
World Access capital stock representing approximately 50% of the voting stock of
World Access voting together as a single class.


                                       123

WORLDXCHANGE VOTING AGREEMENTS



     World Access has entered into separate voting and stock transfer
restriction agreements with the following WorldxChange shareholders: Tom
Cirrito; Roger B. Abbott and Rosalind Abbott, whose shares of WorldxChange
capital stock are owned jointly; Walter Anderson; and Edward S. Soren. Each
voting and stock transfer restriction agreement is substantially similar and
contains the following provisions:



     - each WorldxChange shareholder must vote all of its shares of WorldxChange
       capital stock (whether owned beneficially or of record), as well as any
       other shares of WorldxChange capital stock acquired prior to the
       completion of the WorldxChange merger, in favor of the WorldxChange
       merger and the adoption and approval of the WorldxChange merger
       agreement;



     - each WorldxChange shareholder must vote against any action or agreement
       that would result in a material breach of any covenant, representation or
       warranty of WorldxChange contained in the WorldxChange merger agreement;



     - subject to certain exceptions designed to ensure that the same number of
       shares of WorldxChange capital stock remain subject to the restrictions
       and obligations set forth in the voting and stock transfer restriction
       agreements, no WorldxChange shareholder may:



        - sell, transfer, or otherwise dispose of any shares of WorldxChange
          capital stock or options to acquire shares,



        - trade or take any position, hedge or otherwise, with respect to shares
          of WorldxChange capital stock or options to acquire such shares,



        - enter into any voting arrangement with respect to shares of
          WorldxChange capital stock or options to acquire such shares or



        - take any action that would make any of such WorldxChange shareholder's
          representations or warranties untrue to a material extent or have the
          effect of preventing or materially impeding such WorldxChange
          shareholder from performing any of its obligations;



     - except for Edward S. Soren, Roger B. Abbott and Rosalind Abbott (as
       described below), until six months following the completion of the
       WorldxChange merger, no WorldxChange shareholder may (i) Transfer or
       enter into any contract or understanding with respect to the Transfer of
       any of the shares of World Access common stock to be received by such
       shareholder in the WorldxChange merger or (ii) trade or take any
       position, hedge or otherwise, with respect to the shares of World Access
       common stock received by such shareholder in the WorldxChange merger; and



     - each voting and stock transfer restriction agreement terminates upon the
       first to occur of (i) the termination of the WorldxChange merger
       agreement in accordance with its termination provisions



     Because the above-referenced shareholders hold a significant number of
WorldxChange stock, there is a greater likelihood that the WorldxChange merger
will be approved. The WorldxChange voting agreements represent approximately an
aggregate of           WorldxChange capital stock, which is approximately      %
of the voting stock of WorldxChange.



EXECUTIVE MANAGEMENT SERVICES AGREEMENT WITH WORLDXCHANGE



     World Access has entered into an Executive Management Services Agreement
with WorldxChange under which World Access will manage the operations and
business affairs of WorldxChange as if World Access and WorldxChange had already
completed the WorldxChange merger. The agreement calls for World Access to serve
as the exclusive agent for WorldxChange to provide all management services
required for the operation and management of WorldxChange. World Access has the
authority, to the fullest extent permitted by law, to take all actions and make
all decisions on behalf of WorldxChange in the operation and management of
WorldxChange's day to day business affairs. World Access may contract with third
parties to perform the management services. WorldxChange will reimburse World
Access, on a monthly basis, for all expenses incurred by World Access on behalf
of WorldxChange. WorldxChange is

                                       124
<PAGE>   138


obligated to provide and furnish World Access with any reasonable assistance
and/or information necessary for World Access to perform the services under the
agreement. The agreement will terminate on the first to occur of the following:



     - the parties terminate the WorldxChange merger agreement;



     - the completion of the WorldxChange merger;



     - World Access gives WorldxChange 15 days notice or WorldxChange materially
       breaches the services agreement; or



     - World Access materially breaches the services agreement.



FOOTHILL CAPITAL CORPORATION PARTICIPATION AGREEMENT



     On February 11, 2000, World Access entered into a participation agreement
with Foothill Capital Corporation under which WorldxChange can borrow money. A
participation agreement is an agreement that establishes the terms under which
an additional lender, referred to as a participant and in this case World
Access, provides a portion of the funds to be borrowed under a loan arrangement
to a lead lender. In this participation agreement, Foothill is the lead lender
and will act as agent for World Access in dispersing the funds and in
administering and collecting the loan. The Foothill participation agreement
provides for World Access to provide up to $45.0 million to be advanced by
Foothill to WorldxChange and certain of its subsidiaries. The terms of the loan
are governed by the terms of an existing loan arrangement between Foothill and
WorldxChange. The Foothill loan to WorldxChange is structured as a term loan
which bears interest at a rate of 11% per annum and matures on February 11,
2001. The Foothill loan to WorldxChange is subject to extension by World Access
up to October 1, 2003. Both the term loan and the existing indebtedness to
Foothill under the loan arrangement will be secured by a security interest in
all personal property of WorldxChange. The participation interest of World
Access in the term loan is a last-out participation, which means that at any
time after an acceleration by Foothill of the maturity of the obligations under
the loan arrangement, or the failure of WorldxChange to repay such obligations
in full upon the obligations stated maturity, all amounts collected or received
by Foothill will be applied first to the repayment of all principal, interest
and costs owing to Foothill, and then, to repayment of amounts owing to World
Access.

WorldxChange offers Internet access service in the United States, The
Netherlands, New Zealand, and the United Kingdom. Each of these services is
described in more detail below.



     International and domestic long distance telephone service.  International
and domestic long distance telephone service is accessed from a customer's
billing location, such as the home or office. In North America, Germany,

     Calling card services.  WorldxChange sells pre-paid calling card services
in most of the countries in which it operates. In these countries, customers
access WorldxChange's calling card service by dialing a national toll-free
number or a local access number.



     Internet access services.  WorldxChange introduced its Internet access
service, known as "wxc.net", in June 1999. Customers access WorldxChange's
Internet service by dialing a local or toll-free number. This service is offered
to residential and commercial customers for a fixed monthly price.



     Other retail services.  WorldxChange also provides the other retail

small portion of WorldxChange's revenues and are currently provided as ancillary
offerings.



     - Toll-free service.  WorldxChange provides domestic toll-free service to
       customers in most of the countries in which it operates. Toll-free
       customers in the United States also may obtain an enhanced feature known

       forwarded to alternate numbers until answered.



     - Directory assistance.  WorldxChange provides its U.S. and Canadian long
       distance customers with nationwide directory assistance service 24 hours

<PAGE>   140


     - Dedicated access service.  This service provides customers with a
       dedicated, leased transmission line that connects the customer's business
       directly to our network. This service is marketed to high-volume
       customers in the United States, Germany and the United Kingdom and can be
       used for voice, data, video and Internet access.



     - Operator services.  In the United States, WorldxChange offers 24-hour
       operator service to customers that have pre-selected the WorldxChange
       service. In addition, alternative operator services are offered,
       predominately for U.S. bound calls originating from countries outside the
       United States.



  Wholesale services



     Carrier services.  WorldxChange sells long distance transmission capacity
to carriers through a direct sales force in the United States, Australia,
Canada, New Zealand and the United Kingdom. These customers, which include some
of the largest carriers in the world, may purchase capacity to carry traffic
where they do not have their own routes, where they require additional or
reserve capacity, or where WorldxChange is able to provide more favorable
pricing. These carrier customers use WorldxChange transmission capacity to
provide service to their customers.



     Other wholesale services.  WorldxChange sells transmission capacity to
customers that offer their own branded products and services such as private
label calling cards. In addition, WorldxChange also sells transmission capacity
to resellers for subsequent sale of long distance services to their customers.



THE WORLDXCHANGE NETWORK



     As of March 1, 2000, WorldxChange's network consisted of:



     - 43 switches in ten countries;



     - long-term rights to use on-land cable capacity in the United States;



     - seven satellite earth stations at locations in the United States and
       abroad; and



     - an international transmission network consisting of direct ownership
       interests and long-term rights to use the following undersea cables:


                                   Americas-I


                                      APCN

                                      PTAT




                                  Taino-Caribe




                                    Tasman 2

                               UK-Netherlands 12


                                       127
<PAGE>   141


     WorldxChange also has arrangements to connect with the telecommunications
networks of large telecommunications carriers in each of Australia, Belgium,
Canada, Chile, France, Germany, Guatemala, The Netherlands, New Zealand and the
United Kingdom, as well as arrangements to connect with the networks of major
carriers in the United States.



  Costs of call origination, transmission and termination



     The major components of WorldxChange's costs include the cost of
origination, transmission and termination.



     Origination and termination.  In general, WorldxChange pays a per-minute
fee to originate and terminate calls. WorldxChange can reduce the costs of its
U.S. calls by having a direct connection with the applicable local telephone
companies, which allows WorldxChange to carry a larger portion of each call on
its network. WorldxChange can reduce these costs outside North America by
connecting with the large national carriers. In addition, these connections
allow WorldxChange to provide network access through prefix code dialing and to
transport calls on its network originating in a greater number of locations.



     Transmission.  WorldxChange currently uses a combination of direct
ownership interests in undersea cables, long-term rights to use on-land and
undersea cables, leased lines and arrangements with other carriers, to manage
its transmission costs. WorldxChange usually tries to acquire ownership
interests in long-term rights to use undersea cables and/or that connect cities
with substantial calling traffic between them. However, WorldxChange has used
leased lines in regions where long-term rights of use are either too expensive
or if WorldxChange believes prices for long-term rights of use will decline, or
where long-term rights of use are not available. In some cases, WorldxChange
uses specialized equipment to further increase the capacity of the cables on
which it has long-term rights of use.



     Other.  In addition to the cost of origination, transmission and
termination, the other costs of the WorldxChange network relate primarily to
switching and related equipment, WorldxChange's Internet access equipment and
network management and related software.



  Network operations



     North America.  WorldxChange monitors and maintains the North American
portion of its network from a centralized network operations center in San
Diego, which operates 24 hours a day.



     Overseas operations.  Currently, each of the foreign WorldxChange operating
subsidiaries monitors its own domestic switching and network functions.
WorldxChange's San Diego network operation center monitors the intercontinental,
intercountry and intracountry portions of the WorldxChange network.



     Information systems.  WorldxChange's information systems provide vital
operating information and statistics. These information systems are relied upon
to monitor carrier traffic volumes and patterns and price schedules and are used
to respond quickly to changes in these traffic volumes, patterns and prices and
assist in routing calls to their destination in the least expensive manner.
WorldxChange has installed a wide area network linking all its switch sites,
which coordinates the use of WorldxChange's systems.



  North American network



     WorldxChange has switches in each of the 10 cities listed below that are
connected with the WorldxChange network. WorldxChange expects to relocate its
switch in Seattle to San Francisco by approximately September 1, 2000.



<TABLE>

                                       128
<PAGE>   142


     WorldxChange connects the North American portion of its network with other
regions of the world through interests on the Americas-I, Atlantic Crossing,
Canus 1, Columbus II, HAW-5, Taino-Caribe and TPC-5 undersea cables.



     U.S. network.  Prior to March 1999, WorldxChange leased most of its on-land
cables from MCI WorldCom. As those leases expired, they were converted to
long-term rights of use covering the same capacity. These new arrangements also
allow additional capacity to be added in the future.



     In February 1999, WorldxChange entered into a five-year lease with Level 3
Communications providing additional capacity to carry calls, which is commonly
referred to as transmission capacity. This lease is convertible into a long-term
right of use at the end of the lease.



  European network



     WorldxChange connects the European portion of its network with other
regions of the world through interests on the Atlantic Crossing, Cantat 3,
Columbus-II, F.L.A.G., PTAT, TAT-12/TAT-13, UK-Belgium 6, UK-Germany 6 and
UK-Netherlands 12 undersea cables.



     ACC Acquisition.  In November 1999, WorldxChange acquired the operations of
ACC Corp. in France, Germany and the United Kingdom, and a switch in Italy. This
acquisition expanded WorldxChange's presence in these key European markets.
WorldxChange is in the process of integrating the operations and network
equipment into its existing operations and network. No assurance can be given
that this integration can or will be successful.



  Pacific Rim network



     WorldxChange has a total of nine switches in Australia. WorldxChange
connects the Asia Pacific portion of its network with other regions of the world
through interests on the APCN, Jasuraus, F.L.A.G., Guam-Philippines, PacRim
East, Tasman 2, TPC-5 and US-Japan undersea cables.



  Latin America network



     WorldxChange has a switch in Guatemala City, Guatemala and Santiago, Chile.
WorldxChange connects the Latin American portion of its network through an
ownership interest in the Pan American undersea cable, as well as via satellite
services.



  Network hardware and software



     North America.  WorldxChange uses switches throughout its North American
network. These switches enable WorldxChange to handle large, simultaneous call
volumes, provide high quality service to customers and connect with local
carriers.



     During the fourth quarter of 1998, WorldxChange experienced technical
problems with a new switch that it installed in New York. The problems included
the failure of the switch to record billing information for certain calls.
WorldxChange worked with the vendor of the switch to fix the problems and has
implemented new procedures to detect any similar problems that may arise with
this switch or similar switches in the future. However, there can be no
assurance that WorldxChange will not experience additional problems with its
switching equipment in the future.



     Overseas operations.  WorldxChange uses both switches assembled by
WorldxChange and purchased from outside vendors in markets outside of North
America. The switches assembled by WorldxChange are personal computer-based
devices designed to route calls and provide customer service and billing
functions. Shortly before WorldxChange acquired ACC Corp.'s U.K. operations, ACC
introduced a new billing system in the United Kingdom that has not performed
properly, resulting in delaying billing and billing inaccuracies. WorldxChange
has installed its own billing system in place of the faulty ACC system in the
United Kingdom. However, there can be no assurance that this replacement billing
system will not also experience problems.

     Least cost routing.  WorldxChange uses a combination of hardware and
software to route a call over the most cost-efficient route available at the
time the call is placed. Prices for various destinations fluctuate daily.
WorldxChange uses routing software to frequently revise routing tables,
including accounting for fluctuations in currency exchange rates, as the cost of
certain routes changes. WorldxChange employs a group of employees based in San
Diego who focus on monitoring the routing of calls and seeking to minimize
transmission costs. In addition to the monitoring performed by WorldxChange's
San Diego-based team, a limited amount of the monitoring is performed in each of
the countries in which WorldxChange operates.



  Internet network



     WorldxChange provides Internet access from its network. Internet customers
dial an access number, which connects the customer over the WorldxChange network
to WorldxChange's server in Los Angeles, which ultimately connects the customer
to the Internet. WorldxChange monitors its Internet network from its San Diego
network operations center.



TERMINATION ARRANGEMENTS



     WorldxChange terminates calling traffic through a number of routing
alternatives. These alternatives include resale arrangements, operating
agreements and other termination arrangements as described below.



     Resale arrangements provide WorldxChange with multiple options to route
traffic through switches in various destination countries. These arrangements
generally involve terminating traffic through a third party. For example,
WorldxChange does not have operations in Afghanistan. If one of its customers
wishes to place a call to Afghanistan, WorldxChange can pass the call on to a
third party carrier by purchasing some of the excess capacity on that carrier's
network. The carrier would then terminate the call in Afghanistan either
directly or through another carrier with which it has a relationship.



     During a typical month, WorldxChange may purchase capacity from more than
80 vendors. WorldxChange pays per-minute charges to use much of this capacity,
which subjects WorldxChange to potential price increases. In addition, since
WorldxChange generally obtains this capacity on a short-term basis, it may
experience service cancellations. WorldxChange's vendor contracts provide that
rates are subject to change after notice periods varying from one to 30 days.
The pricing of termination services depends on such factors as the volume of
call traffic and the time of day.



     The Federal Communications Commission or foreign regulatory agencies may
assert that certain of WorldxChange's call termination practices do not comply
with current international settlement rules and policies, such as current
international simple resale rules. WorldxChange could face sanctions, including
forfeitures, if the Federal Communications Commission were to find that certain
of WorldxChange's termination arrangements violate Federal Communications
Commission rules.



SALES AND MARKETING



     WorldxChange uses a number of marketing channels to reach customers. These
channels include direct mail, independent sales agents, multilevel marketing, a
direct sales force, affinity groups, the Internet and media advertising. This
multi-faceted approach allows WorldxChange to customize its marketing for
specific geographic markets and services.



  United States



     WorldxChange uses several channels to market its services to U.S.
customers, including direct mail, its recently introduced "xPectations ML"
multi-level marketing program, direct sales and other channels such as affinity
programs, the Internet and media advertising. These channels are described
below.



     Direct mail.  WorldxChange has developed a number of different direct mail
programs, each designed to appeal to a particular market segment. Direct mail is
used principally to market services to residential and commercial customers who
have not pre-subscribed to WorldxChange's service.

                                       130
<PAGE>   144


     Multilevel marketing.  In October 1998, WorldxChange introduced its
xPectations ML marketing program in the United States. This program involves the
marketing by independent representatives of WorldxChange long distance service,
as well as Internet access and prepaid calling card services, to potential
customers. These representatives also seek to recruit additional xPectations ML
representatives who will in turn market WorldxChange services to their contacts.
Program representatives earn commissions based on revenues collected by
WorldxChange from new customers that they sign up, as well as based on revenues
collected from customers signed up by other representatives that they recruit to
the program.



     WorldxChange also uses the Internet to enhance the xPectations ML program.
xPectations ML representatives can obtain their own Web site, which WorldxChange
hosts. This allows representatives to use a professionally-designed Web site to
market the xPectations ML program to potential customers while allowing
WorldxChange to retain control over the advertising content on the site.



     Direct sales.  WorldxChange employs a direct sales force in the United
States. This direct sales force primarily markets WorldxChange prepaid calling
cards to residential and commercial customers. They also sell excess
transmission capacity to carrier and other wholesale customers. The direct sales
approach is used for these services because they are more complex and usually
have a longer sales cycle.



     Other channels.  WorldxChange also uses affinity programs, the Internet and
media advertising to market its services in the United States. Under the
affinity programs, WorldxChange partners with other companies and organizations
to introduce and sell WorldxChange services. WorldxChange's Internet marketing
strategy includes the recent introduction of the "Virtual PIN" program under
which customers are able to purchase and recharge prepaid calling cards
exclusively through the WorldxChange website, which may be accessed at
www.worldxchange.com.



  Europe



     WorldxChange's marketing activities vary from country to country and are
based on aspects of WorldxChange's marketing programs used throughout the world.
For example, WorldxChange is in the process of beginning the process of
implementing the xPectations ML program in Europe, and WorldxChange has
commenced direct mailing campaigns modeled after its U.S. direct mail programs.



     Marketing activities vary by the kind of service WorldxChange is selling
and the kind of customer WorldxChange is targeting within a particular country.
For example, in the United Kingdom, WorldxChange markets its residential long
distance services through affinity programs and direct mail programs. Direct
sales and independent agents are used to generate commercial long distance
business in the United Kingdom, direct sales are used to generate resale and
carrier and other business there, and independent agents are used to market
WorldxChange's calling card services there.



     In The Netherlands WorldxChange uses direct mail, affinity programs, direct
sales and independent agents to market its residential and commercial long
distance services. WorldxChange also uses direct sales, independent agents and
limited media advertising to market other services in The Netherlands, including
its resale and carrier services.



     In Belgium, WorldxChange relies on direct mail and independent agents to
market its residential long distance services and direct sales to market its
long distance service to commercial customers as well as sales of excess
capacity to carrier and other wholesale customers there. In addition,
independent agents also market WorldxChange's long distance services to Belgian
commercial customers.



     WorldxChange is in the process of establishing a sales and marketing
program in France and Germany. In France, WorldxChange is promoting its
residential long distance service, which currently requires customers to dial a
prefix, through independent agents and direct mail. WorldxChange uses direct
sales to market calling card services and direct sales and independent agents to
market commercial long distance services, which require the use of a four-digit
access code, in France. WorldxChange is marketing its calling card services in
Germany primarily through independent agents and, to a lesser extent, through


                                       131
<PAGE>   145


affinity programs. WorldxChange also has conducted direct mailing campaigns in
both France and Germany.



  The Pacific Rim



     WorldxChange's marketing strategy in Australia and New Zealand uses direct
mailing, independent agents, affinity programs and media advertising to reach
potential residential long distance customers. WorldxChange relies on direct
sales and independent agents to market its long distance service to commercial
customers and direct sales to reach calling card and carrier and other wholesale
customers.



WORLDWIDE OPERATIONS



  U.S. headquarters operations



     WorldxChange's senior management directs WorldxChange's operations and
those of its foreign operating subsidiaries and develops and oversees the
implementation of its overall business strategy from WorldxChange's San Diego
headquarters. Headquarters personnel currently perform centralized financial
services for WorldxChange's foreign operating subsidiaries, including financial
planning and analysis and cost control. WorldxChange's San Diego-based senior
management also coordinate the acquisition of additional transmission capacity,
either leased or purchased, based on the growth of traffic volumes in each
market and helps arrange financing and vendor discounts on behalf of
WorldxChange's foreign operating subsidiaries. In addition, headquarters
personnel perform worldwide treasury functions for WorldxChange's foreign
operating subsidiaries, including managing cash flows between the foreign
operating subsidiaries for the transmission of traffic between them as well as
the allocation of working capital.



     Headquarters personnel also manage the expansion of the WorldxChange
network, which includes determining whether to acquire additional capacity for
existing operations and integrating foreign operating subsidiaries into
WorldxChange's network. Headquarters personnel also coordinate traffic routing
over the network, which involves the programming of WorldxChange's switches to
transport international calls over the route which is most likely to result in
the lowest-cost transmission without sacrificing quality.



  Non-U.S. operations



     Each of WorldxChange's foreign operating subsidiaries is a limited
liability company that is directly or indirectly wholly- or majority-owned by
WorldxChange. WorldxChange's significant operating subsidiaries are briefly
discussed below. WorldxChange has additional subsidiaries in other countries,
but the operations of these subsidiaries are not significant.



  Australian operations



     WorldxChange's Australian operating subsidiary provides local service and
international and domestic long distance service to residential and commercial
customers and sells excess transmission capacity to other carrier customers.
Calling card services are also provided. Current commercial customers in
Australia include multinational corporations, large national companies, as well
as small and medium-sized businesses.



  Belgian operations



     WorldxChange's Belgian operating subsidiary provides domestic and
international long distance and calling card services to residential and
commercial customers. It also sells excess transmission capacity to other
telecommunications carriers.



  Dutch operations



     WorldxChange's Dutch operating subsidiary provides local service and
domestic and international long distance service to residential and commercial
customers and call shops. Commercial customers include


                                       132
<PAGE>   146


small and medium-sized businesses. This operating subsidiary also has reseller,
carrier and other wholesale customers.



  French operations



     WorldxChange's French operating subsidiary provides local service, domestic
and international long distance and calling card services to residential and
commercial customers. It also sells excess transmission capacity to other
telecommunications carriers.



  German operations



     WorldxChange's German operating subsidiary provides local service, domestic
and international long distance and calling card services to residential and
commercial customers. It also sells excess transmission capacity to other
telecommunications carriers.



  New Zealand operations



     WorldxChange's New Zealand operating subsidiary provides domestic and
international long distance services to residential and commercial customers, as
well as toll-free services.



  U.K. operations



     WorldxChange's U.K. operating subsidiary provides local service and
domestic and international long distance service to residential and commercial
customers and other carriers in the United Kingdom, as well as calling card
services. Current commercial customers include small and medium-sized
businesses.



EMPLOYEES



     As of June 30, 2000, WorldxChange employed approximately 876 people,
including officers, administrative and sales personnel, of which 786 were
full-time employees and 90 were part-time employees.



PROPERTIES



     WorldxChange's principal offices are located at 9999 Willow Creek Road, San
Diego, California, where WorldxChange occupies approximately 36,100 square feet
under a lease that expires on August 31, 2002.



     WorldxChange also maintains a 24,300 square-foot office at 9775
Businesspark Avenue, San Diego, California, which houses WorldxChange's human
resources, technical and certain other corporate functions. This lease expires
on July 31, 2002.



     WorldxChange leases all of the facilities in which its switches are
installed. These leases are generally multi-year leases. In addition, our
foreign operating subsidiaries lease facilities for their respective corporate
offices and switch sites.



LEGAL PROCEEDINGS



     In May 1997, the California Public Utilities Commission issued an order
revoking WorldxChange's authority to provide intrastate calling service in
California and imposing certain other fines and penalties, including, among
other things, a $19.6 million fine, against WorldxChange based on the California
Public Utilities Commission's finding that WorldxChange had violated California
laws and regulations requiring WorldxChange to obtain prior consumer
authorization before switching consumers' long distance carriers. WorldxChange
has paid $2.0 million of the $19.6 million fine, with the balance suspended so
long as WorldxChange is not found to have committed any future violations of
statutes or California Public Utilities Commission directives. Under the
California Public Utilities Commission's order, the sanctions and fines are
binding on any successor to WorldxChange, unless the California Public Utilities
Commission orders otherwise. WorldxChange has implemented a number of policies
and procedures


                                       133
<PAGE>   147


designed to help reduce the likelihood of future allegations of the kind leading
to the California Public Utilities Commission's order. However, there can be no
assurance that additional allegations of wrongdoing will not be brought against
WorldxChange in the future or that, if such allegations are made, that they
would not result in substantial expense and/or liability to WorldxChange. For
example, if such allegations were to be made in California and WorldxChange were
found to have violated statutes or any California Public Utilities Commission
directives, WorldxChange would be subject to paying the $17.6 million portion of
the California Public Utilities Commission fine that is currently suspended, as
well as potentially other fines and penalties, which could be substantial. If
WorldxChange were required to pay the suspended portion of the California Public
Utilities Commission fine and/or any such additional fines or penalties,
WorldxChange's business would be harmed. In September 1995, the California
Attorney General notified WorldxChange that it was investigating alleged
violations by WorldxChange of certain consumer protection laws. WorldxChange
commenced negotiations for a settlement with the California Attorney General,
but these negotiations were terminated in 1997 in connection with the California
Public Utilities Commission proceedings described above without any settlement
agreement. It is possible that the California Attorney General could reopen its
investigation of WorldxChange or commence a lawsuit against WorldxChange based
on the same or new or additional allegations of wrongdoing by WorldxChange. If
such investigation were to be reopened or such lawsuit were to be commenced,
WorldxChange would be forced to respond and defend itself, which could result in
significant expense and diversion of WorldxChange's management's time and
resources. In addition, WorldxChange could incur significant liability pursuant
to a settlement or adverse judicial ruling in connection with any such
proceedings.



     WorldxChange was also notified in September 1995 by the attorneys general
of five other states that they were investigating alleged violations by
WorldxChange of certain consumer protection laws. WorldxChange settled these
allegations by paying an aggregate amount of $475,000 and, without admitting
liability, consenting to civil injunctions.



     WorldxChange is a party, from time to time, to certain legal and
administrative proceedings, claims and inquiries that arise in the ordinary
course of its business, as well as to certain other litigation, some of which
proceedings, claims and inquiries involve claims for substantial amounts of
damages. Although the ultimate outcome of these proceedings, claims and
inquiries is uncertain, WorldxChange does not believe that any of these
proceedings, claims or inquiries will materially harm WorldxChange's business.

              WORLDXCHANGE MANAGEMENT'S DISCUSSION AND ANALYSIS OF


                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS



     The following discussion should be read in conjunction with WorldxChange's
financial statements, the notes thereto and the other financial data included
elsewhere in this joint proxy statement/prospectus.



OVERVIEW



  General



     WorldxChange is a global telecommunications company that specializes in
providing high-quality, low-cost domestic and international telecommunications
services. WorldxChange has established operations in North America, Europe and
the Pacific Rim. WorldxChange's global facilities include switches located in
major metropolitan areas in ten countries.



  Revenues



     WorldxChange obtains its revenues from providing international and domestic
telecommunication services to retail and wholesale customers. WorldxChange's
retail revenues are derived from usage generated by residential and commercial
customers. WorldxChange's wholesale revenues are composed of revenues generated
from sales to other U.S. and foreign telecommunications carriers and resellers.



     Revenues are derived mainly from the number of minutes (or fractions
thereof) used by WorldxChange's customers and billed by WorldxChange and are
recognized upon completion of the calls, as well as, to a lesser extent, from
certain recurring monthly fees that we recognized when services are provided.
Prices for long distance calls have decreased substantially in many of the
markets that WorldxChange serves due to increased competition and to cost
reductions associated with technological advancements. As a consequence,
WorldxChange has experienced and expects to continue to experience declining
revenues per minute in these markets.



     WorldxChange's revenues have increased from $331.7 million in fiscal 1997
to $421.6 million in fiscal 1999. WorldxChange's total retail revenues have
grown from $139.7 million in fiscal 1997 to $212.0 million in fiscal 1999.
WorldxChange's foreign retail revenues have increased from $28.1 million in
fiscal 1997 to $69.4 million in fiscal 1999. WorldxChange has achieved its
retail growth primarily through the use of direct mail marketing campaigns in
Europe, the U.S. and Australia, as well as through agent sales.



     The following table reflects percentages of total revenue from
WorldxChange's North American and non-North American operations and by type of
customer for fiscal 1997, 1998, and 1999 and the six months ended March 31, 1999
and 2000:

     In November 1999, WorldxChange purchased the European operations of ACC
Corp, which is referred to in this discussion as ACC Europe. The acquisition of
ACC Europe has been accounted for using the purchase method of accounting.
Accordingly, the results of ACC Europe's operations have been included from the
date of acquisition, November 4, 1999. The increase in revenues outside North
America during the six months ended March 31, 2000 has been primarily
attributable to this purchase.



  Cost of services



     Cost of services is WorldxChange's largest expense and consists of both
variable and fixed costs. Variable costs include costs associated with the
origination and termination of calls. Virtually all calls WorldxChange carries
must be originated and terminated by a local carrier. Variable costs also
include the cost of transmitting calls using the long distance facilities of
other carriers, which WorldxChange uses if it cannot carry the traffic over its
own network. These local and long distance carriers charge on a per minute
basis. WorldxChange's fixed costs consist of leased point-to-point cable
capacity, which typically requires fixed monthly payments regardless of usage.
Because the cost of leased lines is fixed, transmitting a greater portion of
WorldxChange's traffic over the leased lines reduces its incremental marginal
transmission costs. Accordingly, once certain volume levels are reached, leased
line capacity can be more cost-effective than capacity acquired from other long
distance carriers.



     Capitalized costs associated with WorldxChange's ownership interests in
cables and long-term rights of use in cables or other facilities are expensed in
depreciation and amortization and are therefore not accounted for as part of
cost of services. To the extent WorldxChange's expanded use of its interests in
cables or long-term rights of use in cables or other facilities reduces its
utilization of leased lines and the facilities of other long distance carriers,
WorldxChange believes the increase in depreciation expense associated with its
interests in cables or long-term rights of use in cables or other facilities
will be offset by a decrease in its variable and fixed cost of services.



  Selling, general and administrative expenses



     WorldxChange's selling, general and administrative expenses consist of
commissions paid to its independent agents and direct sales force, advertising
and promotional costs, direct mail expenses, employee compensation, occupancy,
insurance, professional fees, bad debt expense, expenses relating to customer
service operations and the costs related to maintaining and supporting its
systems. As WorldxChange starts operations in new markets, it incurs significant
start-up costs associated with establishing a supporting infrastructure,
particularly for hiring and training of personnel, leasing office space and
paying various fees in conjunction with its business. As WorldxChange increases
its sales and marketing efforts and commences operations in new markets,
WorldxChange expects that its sales and marketing expenses will increase.



  Depreciation and amortization expenses



     Depreciation and amortization expenses consist of depreciation of all fixed
assets and computer equipment, as well as amortization of the fixed costs
associated with WorldxChange's:



     - owned and leased switching platforms, which have been capitalized and are
       being amortized over their estimated useful lives or the term of the
       lease, which is typically five to seven years; and



     - Interests in cables or long-term rights of use in cables or other
       facilities interests in international undersea and on-land fiber-optic
       cable systems, which are being amortized over their estimated useful
       lives, which is typically 20 years.


                                       136
<PAGE>   150


     WorldxChange expects depreciation and amortization expenses to increase
significantly as a result of the amortization of the $68.2 million of goodwill
and $17.0 million of customer list recorded in association with its purchase of
ACC Europe. Customer list is amortized over five years and goodwill is amortized
over 20 years.



  Interest expense



     Interest expense principally consists of interest payable on WorldxChange's
revolving credit agreement, subordinated notes, notes payable and capital
leases. As WorldxChange incurs additional indebtedness to expand its operations,
it expects interest expense to increase.



  Income taxes



     As of September 30, 1999, WorldxChange has net operating loss carryforwards
available for federal, state, and foreign tax purposes of approximately $74.2
million, $45.0 million and $55.0 million, respectively. The federal net
operating loss carryforwards will begin expiring in 2007, and the state net
operating loss carryforwards begin to expire in 1999 and will continue to expire
through 2003, unless previously utilized. The Canadian and Netherlands net
operating loss carryforwards, in the amounts of $6.2 million and $5.5 million,
respectively, will begin expiring in 2003. WorldxChange's other foreign net
operating loss carryforwards carry forward indefinitely. The realization of
future domestic benefits from net operating loss carryforwards may be limited
under Section 382 of the Internal Revenue Code if certain cumulative changes
occur in its equity ownership. WorldxChange has not recognized any income tax
benefit in its historical financial statements because it believes the
realization of the deferred tax asset is uncertain. See Note 7 to Consolidated
Financial Statements.



  Pro-forma quarterly results of operations



     On November 4, 1999, WorldxChange purchased ACC Europe. The following table
sets forth supplemental unaudited pro-forma quarterly results of operations for
each of the past six quarters for the period ended March 31, 2000 that
WorldxChange's management believes is important to provide an understanding of
its results of operations. The supplemental unaudited pro-forma quarterly
Statements of Operations assumes that the purchase of ACC Europe had been
completed as of the beginning of the periods presented. This information has
been prepared substantially on the same basis as the audited financial
statements appearing elsewhere, and all necessary adjustments, consisting only
of normal recurring adjustments, have been included in the amounts stated below

     Revenues.  WorldxChange's revenues increased in each of the first five
quarters presented, primarily due to increased revenues in North America and
Europe. In October 1998, WorldxChange initiated a multilevel marketing program
in North America to augment its direct mail marketing efforts and provide an
added retail sales distribution channel. In addition, we began to offer and
market calling card products. In Europe, revenues have grown due to increased
marketing expenditures on direct mail campaigns and direct sales. The decline in
revenue in the quarter ended March 31, 2000 is primarily attributable to
reductions in North America of operator service revenue. WorldxChange made a
strategic decision during the latter part of fiscal 1999 to reduce both
marketing and sales efforts in the operator service market.



     Cost of Services.  The gross margin percentages ranged from 20.2% to 22.0%
over the most recent five quarters presented. The fluctuations between quarters
were the result of changes in the mix of retail and wholesale revenue, margin
degradations due to the expansion of network infrastructure in Europe, margin
improvements gained in North America due to WorldxChange's purchase of its
on-land fiber optic cable capacity and declining North American carrier margins
throughout the periods presented. The decline in gross margins in the quarter
ended March 31, 1999 from the quarter ended December 31, 1998 was due to a
decline in margins in Europe. The decline in European margins was due to
expansion of WorldxChange's European leased network facilities. The European
leased network facilities were increased to obtain interconnection with the
telecommunications networks of dominant carriers in Europe and to meet the
minimum capacity levels required for this interconnection. The facilities were
also expanded to provide WorldxChange with the capacity needed for its expected
future growth.



     Selling, general and administrative expenses.  Selling, general and
administrative spending levels fluctuated throughout most of the periods
presented due to increases and decreases in sales and marketing spending and the
continued expansion of WorldxChange's European infrastructure. In spite of
increased sales and marketing spending during most of the quarters, selling,
general and administrative expenses as a percentage of revenues continued to
decrease over the periods. Selling, general and administrative levels decreased
in the quarter ending March 31, 2000 from the quarter ended December 31, 1999
due to a decline in promotional and selling expense in North America.
WorldxChange plans to focus more of its promotional and selling efforts and
resources in Europe.


                                       138
<PAGE>   152


     Depreciation and amortization expenses.  Depreciation and amortization
increased during the quarters as WorldxChange made approximately $100.0 million
in capitalized purchases during this period to expand the geographic scope and
available capacity of its network.



     Interest expense.  Interest expense fluctuated commensurate with the level
of quarterly indebtedness. The decline in interest expense in the quarter ended
March 31, 1999 from the quarter ended December 31, 1998 was due to a reduction
in WorldxChange's notes payable of $8.5 million. The increase of interest
expense in the quarters ended June 30, 1999, December 31, 1999 and March 31,
2000 were due to an increase in WorldxChange's indebtedness associated with the
purchase of its on-land fiber optic capacity in the United States and capital
lease obligations.



RESULTS OF OPERATIONS



  Six months ended March 31, 2000 compared to six months ended March 31, 1999



     Revenues.  Total revenues increased by 52.8% to $291.6 million in the first
six months of fiscal 2000 from $190.7 million for the first six months of fiscal
1999. The increase in revenues was primarily attributable to revenues from ACC
Europe, which WorldxChange acquired in November 1999, and continued internal
growth in WorldxChange's retail and carrier revenues, offset by a decrease in
operator services revenues in North America.



     In North America, revenues increased by 19.3% to $175.8 million for the
first six months of fiscal 2000 from $147.4 million for the first six months of
fiscal 1999. The increase was primarily attributable to an increase in
WorldxChange's retail revenue from $56.1 million in the first six months of
fiscal 1999 to $87.3 million for the same period of fiscal 2000. This increase
in revenue is attributable to WorldxChange's multilevel marketing program which
was initiated in October 1998 and its expanded sales and marketing efforts for
its calling card products. The multilevel marketing program was initiated to
augment WorldxChange's direct mail marketing efforts and provide an additional
retail sales distribution channel. Operator services revenue declined 65.1% to
$6.5 million for the first six months of fiscal 2000 from $12.9 million for the
first six months of fiscal 1999. WorldxChange made a strategic decision during
the latter part of fiscal 1999 to reduce both marketing and sales effort in the
operator services market. WorldxChange's North American carrier revenues
increased 4.5% to $81.9 million for the first six months of fiscal 2000 from
$78.4 million for the first six months of fiscal 1999.



     In the Pacific Rim, revenues decreased by 12.8%, to $25.8 million for the
first six months of fiscal 2000 from $29.6 million for the first six months of
fiscal 1999. This decline was primarily attributable to the loss of
WorldxChange's largest reseller customer, which accounted for approximately 9.0%
of this region's revenues. This reseller was acquired by a competitor and the
competitor began to migrate the reseller's customer traffic off WorldxChange's
network in October 1998. The balance of the reduction was due to decreases in
pricing resulting from competitive pricing pressures and declining costs.



     In Europe, revenues increased by 556.9% for the first six months of fiscal
2000 to $90.0 million from $13.7 million for the same period of fiscal 1999,
primarily due to the acquisition of ACC Europe. ACC Europe contributed $76.1
million of total European revenue. The balance of the increase in revenues was
due to geographic expansion in the region and increased direct mail campaigns in
the region.



     Cost of services.  Cost of services increased by 52.7% to $230.2 million
for the first six months of fiscal 2000 from $150.8 million for the same six
months in fiscal 1999 and, as a percentage of revenue, decreased to 78.9% from
79.0%, respectively. Cost of services as a percentage of revenue decreased
primarily as a result of higher margins associated with ACC Europe's revenues
and an overall increase in retail revenues as a percentage of total revenues.
Retail revenues have higher gross margins than the gross margins associated with
carrier revenues. ACC Europe's margins are higher because the percentage of its
revenues that are retail revenues is greater than the comparable percentage for
WorldxChange excluding ACC Europe. North America cost of services as a
percentage of revenues increased from 84.0% in the first six months of fiscal
1999 to 84.3% in the first six months of fiscal 2000. The increase was
associated with a decline in carrier revenue margins, partially offset by a
higher revenue mix of retail revenues. Cost of


                                       139
<PAGE>   153


services as a percentage of revenues remained constant in the Pacific Rim. In
Europe, excluding ACC Europe, cost of services as a percentage of revenues
increased from 82.4% for the first six months of fiscal 1999 to 94.2% for the
same period of fiscal 2000. This increase was due to additional costs associated
with obtaining interconnection with the telecommunications networks of dominant
local carriers in various countries and meeting their minimum capacity level
requirements, as well as expansion of WorldxChange's European network
infrastructure.



     Selling, general and administrative expenses.  Selling, general and
administrative expenses increased by 48.0% to $84.6 million for the first six
months of fiscal 2000 from $57.1 million for the same period in fiscal 1999 and,
as a percentage of revenues, decreased from 30.0% to 29.0%. The increase in
selling, general and administrative expenses was due to the purchase of ACC
Europe, increased spending in Europe and direct costs associated with increases
in revenues. These expenses in Europe, excluding ACC Europe, increased from $8.2
million for the first six months of fiscal 1999 to $14.9 million for the first
six months of fiscal 2000. This increase was due to increased sales, operations
and back office infrastructure to support sales growth and the expansion into
new markets in Europe. Selling, general and administrative expenses in the
Pacific Rim remained relatively flat. Selling, general and administrative
expenses in North America increased to $40.6 million for the first six months of
fiscal 2000 from $38.1 million for the same period of fiscal 1999. The increase
in these expenses in North America was due to increased commissions, billing
costs and bad debt expense associated with increased revenues. As a percentage
of revenue, North America selling, general and administrative expenses decreased
to 20.7% in the first six months of fiscal 2000, from 22.6% in the first six
months of fiscal 1999. Included in selling, general and administrative expenses
was bad debt expense of $10.9 million for the first six months of fiscal 2000
and $8.4 million for the same period in fiscal 1999. The increase in bad debt
expense was attributable to an increase in revenue. Bad debt expense as a
percentage of revenue decreased to 3.8% in the first six months of fiscal 2000
from 4.4% in the same period of fiscal 1999. Bad debt expense as a percentage of
revenue has improved as management has enhanced its account monitoring and
reporting systems designed to reduce bad debt exposure and allow for timely
identification, follow-up and mitigation of potential risk customers.
WorldxChange expects selling, general and administrative expenses to continue to
grow as revenues increase and as it continues to expand into new markets and
build infrastructure.



     Depreciation and amortization expenses.  Depreciation and amortization
expenses increased to $21.8 million for the first six months of fiscal 2000 from
$7.7 million in the first six months of fiscal 1999. The increase in
depreciation and amortization was due to the amortization of $85.2 million of
intangible assets recorded in association with the purchase of ACC Europe and
$12.2 million of goodwill recorded in association with the purchase of a
minority interest in WorldxChange's Australian operations and increased
depreciation associated with the build-out of network and supporting
infrastructure.



     Interest expense.  Interest expense increased by 73.1% to $13.5 million for
the first six months of fiscal 2000 from $7.8 million in the first six months of
fiscal 1999. The increase was primarily due to the debt associated with the
purchase of ACC Europe and the on-land fiber optic capacity.



  Fiscal 1999 compared to fiscal 1998



     Revenues.  Total revenues for fiscal 1999 increased by 5.7% to $421.6
million from $398.9 million for fiscal 1998. The increase in revenues was
primarily associated with an increase in European and North American retail
revenues, which was partially offset by a decrease in operator services revenues
in North America.



     In North America, revenues increased for fiscal 1999 by 4.9% to $337.5
million from $321.8 million in fiscal 1998. The increase in revenue was
primarily attributable to increased retail and carrier revenues offset by a
decline in operator services revenue. Retail revenues increased 15.3% from
$123.5 million in fiscal 1998 to $142.4 in fiscal 1999. This increase in retail
revenue is attributable to increased promotional spending and the introduction
of WorldxChange's multilevel marketing program. In October 1998, WorldxChange
initiated a multilevel marketing program to augment its direct mail marketing
efforts and provide an added retail sales distribution channel. Also
contributing to the increase in retail revenue was


                                       140
<PAGE>   154


WorldxChange's expanded sales and marketing efforts for its calling card
products. Revenue derived from operator services decreased 43.5% from $40.5
million for fiscal 1998 to $22.9 million for fiscal 1999. The decline in
operator services revenues was due to WorldxChange's strategic decision to
reduce marketing efforts in the operator services market. WorldxChange's North
American carrier revenues increased 9.1% to $172.0 million for fiscal 1999 from
$157.7 million for fiscal 1998.



     In the Pacific Rim, revenues decreased by 4.8%, to $55.6 million for fiscal
1999 from $58.4 million for fiscal 1998. This decline was primarily attributable
to the loss of WorldxChange's largest reseller customer, which accounted for
approximately 23% of this region's revenues. This reseller was acquired by a
competitor, and the competitor began to migrate the reseller's customer traffic
off WorldxChange's network in October 1998. A substantial portion of the
reduction in revenues attributable to the reseller was offset by increased
retail revenue generated through direct mail and agent sales.



     In Europe, revenues increased by 52.4% for fiscal 1999 to $28.5 million
from $18.7 million for the same period of fiscal 1998, primarily due to
increases in retail revenues. Retail revenues increased due to geographic
expansion in the region and increased direct mail campaigns in the region.



     Cost of services.  Cost of services increased by 14.3% to $328.3 million
fiscal 1999 from $287.3 million for fiscal 1998 and, as a percentage of revenue,
increased to 77.9% from 72.0%. Cost of services as a percentage of revenue
increased primarily as a result of decreasing margins associated with carrier
revenues. Carrier revenues as a percentage of total revenues increased for
fiscal 1999 compared to fiscal 1998. These revenues have lower gross margins
than the gross margins from retail and operator services revenues. Cost of
services as a percentage of revenues increased in North America from 75.7% for
fiscal 1998 to 81.6% for fiscal 1999. Cost of services as a percentage of
revenues decreased in the Pacific Rim from 77.0% for fiscal 1998 to 72.8% for
fiscal 1999. Cost of services as a percentage of revenues increased in Europe
from 84.4% for fiscal 1998 to 88.1% for fiscal 1999. This increase was due to
additional costs associated with the expansion of WorldxChange's European
network infrastructure.



     Selling, general and administrative expenses.  Selling, general and
administrative expenses increased by 8.0% to $124.1 million for 1999 from $115.0
million for fiscal 1998 and, as a percentage of revenues, increased from 28.8%
to 29.4%. The increase was primarily due to increased spending in Europe and the
Pacific Rim, offset in part by reduced general and administrative spending in
North America. These expenses in Europe increased from $10.8 million for fiscal
1998 to $21.2 million for fiscal 1999. This increase was due to increased sales,
operations and back office infrastructure to support sales growth and the
expansion into new markets in Europe. Selling, general and administrative
expenses in the Pacific Rim increased by 6.0% to $21.3 million for fiscal 1999
from $20.1 million for fiscal 1998. This increase was due to growth in the
supporting infrastructure and increased staffing levels in customer service in
WorldxChange's Pacific Rim markets. Selling, general and administrative expenses
in North America decreased to $81.5 million for fiscal 1999 from $84.1 million
for fiscal 1998. The decline in these expenses in North America was due to
WorldxChange's efforts to streamline its North American operations by reducing
personnel costs and overall spending. Included in selling, general and
administrative expenses was bad debt expense of $15.2 million for fiscal 1999
and fiscal 1998. Bad debt expense as a percentage of revenue decreased to 3.6%
in fiscal 1999 from 3.8% in fiscal 1998. Bad debt expense as a percentage of
revenue has improved as management has enhanced its account monitoring and
reporting systems designed to reduce bad debt exposure and allow for timely
identification, follow-up and mitigation of potential risk customers.



     Depreciation and amortization expenses.  Depreciation and amortization
expenses increased by 43.6% to $17.7 million for fiscal 1999 from $12.3 million
of fiscal 1998. The increase in depreciation and amortization was due to the
continued build-out of WorldxChange's network and supporting infrastructure.



     Interest expense.  Interest expense increased by 41.3% to $16.9 million for
fiscal 1999 from $11.9 million in fiscal 1998. The increase was primarily due to
interest associated with the subordinated promissory notes issued between May
and August of 1998.


                                       141
<PAGE>   155


  Fiscal 1998 compared to fiscal 1997



     Revenues.  Total revenues for fiscal 1998 increased by 20.3% to $398.9
million from $331.7 million for fiscal 1997. Growth in revenues during 1998 was
attributable primarily to an increase in traffic volume, offset in part by a
decline in average carrier prices. Total revenues for fiscal 1998 were also
negatively impacted by WorldxChange's inability to bill for certain calls during
the period due to technical difficulties with a newly installed switch.



     In North America, WorldxChange's revenues for fiscal 1998 increased by
10.3% to $321.8 million, primarily as a result of substantial increases in sales
of residential and operator services. Revenues from residential customers
increased by 13.5% to $116.1 million for fiscal 1998 from $102.3 million for
fiscal 1997. The increase in residential revenues was due to increased
promotional spending in late fiscal 1997, which stimulated growth in the first
half of fiscal 1998. Revenues from operator services increased by 51.7% to $40.5
million for fiscal 1998 from $26.7 million for fiscal 1997. Revenues from
carrier and commercial customers were relatively stable.



     In the Pacific Rim, revenues increased by 139.3% to $58.4 million for
fiscal 1998 from $24.4 million for fiscal 1997, reflecting significant increases
in the usage of WorldxChange's services by residential and commercial customers.



     In Europe, revenues increased by 19.9% to $18.7 million for fiscal 1998
from $15.6 million for fiscal 1997, reflecting significant increases in the
usage of WorldxChange's services by residential and commercial customers.



     Cost of services.  Cost of services increased by 22.2% to $287.3 million
for fiscal 1998 from $235.0 million for fiscal 1997 and, as a percentage of
revenues, increased to 72.0% for fiscal 1998 from 70.9% for fiscal 1997. Cost of
services increased as a percentage of revenues as a result of lower margins
associated with carrier revenues. Although WorldxChange's carrier costs
decreased during fiscal 1998 due to competitive pricing pressures, it was unable
to maintain the gross margins WorldxChange experienced in 1997. In addition,
during the fourth quarter of fiscal 1998, WorldxChange experienced technical
problems with a newly installed switch. The problems included the failure of the
switch to record billing information for certain calls. As a result,
WorldxChange was unable to bill for all of its calls. This resulted in
WorldxChange's incurring costs for calls with no corresponding revenues, which
reduced overall gross margins.



     Selling, general and administrative expenses.  In fiscal 1998, selling,
general and administrative expenses increased by 1.3% to $115.0 million from
$113.5 million for fiscal 1997 and, as a percentage of revenue, decreased to
28.8% for fiscal 1998 from 34.2% for fiscal 1997. A significant portion of the
increase in spending was directly related to the increase in revenues, as
marketing and sales expenses increased due to increases in commissions,
marketing, and other related expenses. Selling, general and administrative
expenses, as a percentage of revenue, declined primarily due to a reduction in
bad debt expense. Bad debt expense was $15.2 million in fiscal 1998 compared to
$22.3 million for fiscal 1997. Bad debt expense as a percentage of revenue
decreased to 3.8% for fiscal 1998 from 6.7% in fiscal 1997. The reduction in bad
debt expense was due to WorldxChange increasing its efforts in the initial
review for credit approval for new customers and has enhanced its
account-monitoring and reporting systems designed to reduce its bad debt
exposure and allow for timely recognition of risk customers. Furthermore,
WorldxChange increased the number and quality of its credit and collection staff
worldwide.



     Depreciation and amortization expenses.  Depreciation and amortization
expenses increased by 41.4% to $12.3 million for fiscal 1998 from $8.7 million
for fiscal 1997. This increase was due to the expansion of WorldxChange's
network and capital deployed as it entered new markets.



     Interest expense.  Interest expense increased by 36.8% to $11.9 million in
fiscal 1998 from $8.7 million in fiscal 1997. The increase in interest was due
to the increase in the level of debt and capital lease obligations WorldxChange
incurred in order to fund its network expansion.

LIQUIDITY AND CAPITAL RESOURCES



     As a consequence of the rapid expansion of WorldxChange's business and its
historical capital constraints, WorldxChange has incurred cumulative net losses
from inception in 1991 through March 31, 2000. These losses and associated
negative cash flows resulted primarily from start-up costs, marketing expenses
and capital expenditures required to build and deploy its network. WorldxChange
has utilized cash provided from financing activities to fund losses and capital
expenditures. The sources of this cash have primarily been private placement
equity offerings, the issuance of subordinated debt, capital lease and vendor
financing and WorldxChange's revolving credit facility.



     For the six-month period ending March 31, 2000, WorldxChange's net cash
used in operating activities was $24.3 million, primarily consisting of a net
loss of $59.3 million, offset by an increase in operating working capital of
$3.8 million and $32.8 million of non-cash charges consisting of the provision
for bad debts and depreciation and amortization. Cash used in investing
activities totaled $58.4 million, which was primarily for the purchase of ACC
Europe. Cash provided by financing activities consisted primarily of the net
private placement equity offering totaling $48.7 million and increased net
borrowings of $14.7 million, offset by debt and capital lease payments of $9.2
million. As of March 31, 2000 WorldxChange had approximately $9.6 million in
cash.



     For fiscal 1999, cash used in operating activities was $31.5 million,
primarily composed of a net loss of $63.9 million, offset by an increase in
operating working capital and non-cash charges relating to the provision for bad
debt and depreciation and amortization. Cash used in investing activities,
primarily capital expenditures, totaled $27.6 million in fiscal 1999. Cash
provided by financing activities amounted to $76.3 million, primarily consisting
of the receipt of $101.6 million in private placement equity offerings, offset
by repayments of subordinated debt, certain notes payable and capital lease
obligations. As of September 30, 1999, WorldxChange had $38.0 million in cash.



     As of September 30, 1998, WorldxChange had approximately $20.9 million in
cash. WorldxChange's net cash used in operating activities was $31.7 million in
fiscal 1998, primarily caused by a net loss of $27.5 million and a decrease in
operating working capital of $28.0 million, offset by $27.5 million of non-cash
charges consisting of the provision for bad debts and depreciation and
amortization. Cash used for investing activities totaled $12.0 million in fiscal
1998, which was for capital expenditures. The capital expenditures primarily
consisted of purchases associated with the expansion of WorldxChange's network,
computers, and general equipment. Net cash provided by financing activities
totaled $60.5 million for fiscal 1998, which consisted of $55.2 million in
proceeds from the issuance of subordinated debt, $10.0 million from a private
placement equity offering and a $0.7 million increase in WorldxChange's
revolving credit facility, offset by $5.3 million in the repayment of debt and
capital lease obligations. Net cash used in operating activities for fiscal 1997
was $7.2 million and net cash used in investing activities, principally capital
expenditures, was $10.9 million for fiscal 1997. WorldxChange financed these
capital expenditures primarily with long-term debt. Net cash provided by
financing activities for fiscal 1997 was $18.8 million.



     In October 1997, the California Public Utilities Commission issued its
final order which imposed a $19.6 million fine against WorldxChange, $2.0
million of which was charged against earnings in fiscal 1997 and was paid in
April 1998 and the remainder of which is suspended by the California Public
Utilities Commission subject to WorldxChange's refraining from committing any
violations of statutes or California Public Utilities Commission directives. See
"Certain Information Regarding WorldxChange -- Legal Proceedings".



     Capital expenditures, including assets acquired by incurring capital lease
obligations, for fiscal 1997, 1998 and 1999 totaled $19.4 million, $22.4
million, and $81.0 million, respectively. Capital expenditures, including assets
acquired by incurring capital lease obligations, for the six-month period ended
March 31, 2000 totaled approximately $16.3 million. Pursuant to the WorldxChange
merger agreement, WorldxChange is subject to certain restrictions in making
capital expenditures and other investments until the completion of the merger.
WorldxChange expects to incur an additional $7.0 million in capital expenditures
prior to the completion of the WorldxChange merger. WorldxChange expects to fund
these expenditures through vendor or other third party financing.

     WorldxChange has utilized capital lease and vendor financing to assist in
financing the building of its network, systems and infrastructure. As of March
31, 2000, the balance of capital lease financing obligations totaled $41.1
million, primarily relating to the lease of its switching platforms in North
America. In addition, as of March 31, 2000 WorldxChange had outstanding $39.0
million vendor financed note payables relating to various fiber optic cable
acquisitions.



     WorldxChange has a billing and collection services agreement with Zero Plus
Dialing Incorporated. Under this services agreement, WorldxChange has the
ability to sell certain receivables, subject to full recourse provisions, to
Zero Plus Dialing. At March 31, 2000 the maximum amount to be sold under this
agreement was sold, and WorldxChange was contingently liable for approximately
$692,000.



     In March 1997, WorldxChange entered into its credit facility, which
consists of an accounts receivable-based revolving credit facility and a term
loan. In February 2000, the credit facility was amended to increase the maximum
borrowing capacity, add a bridge loan, extend the maturity date of the revolving
credit agreement and term loan and reduce the interest rate charge. The credit
facility allows WorldxChange to borrow up to a maximum of $65.0 million, subject
to certain restrictions and borrowing base limitations. The maximum available
borrowing base under the revolving credit agreement is $30.0 million and is
determined as a specified percentage of eligible accounts receivable. The
balance outstanding on the revolving credit agreement is reduced by the
application of payments received on collections of accounts receivable. The
accounts receivable revolving credit facility had an outstanding balance of
approximately $16.5 million at March 31, 2000, and $10.5 million available for
borrowing pursuant to the borrowing base limitations. This facility bears
interest at the prime rate plus 1.75% and is repaid through collections of
accounts receivable. The term loan was issued in the amount of $5.0 million,
which at March 31, 2000 had an outstanding balance of approximately $4.7
million, bears interest at the prime rate plus 5.00% and requires monthly
reductions of principal of $300,000 plus interest. The bridge loan has a maximum
borrowing availability of $30.0 million, bears interest at 11% and matures on
February 11, 2001. The maturity date may be extended until October 1, 2003 by
the bridge loan participant. As part of the amended agreement and the
WorldxChange merger agreement, World Access agreed to participate in the bridge
loan and agreed to fund the $30.0 million under the agreements. As of March 31,
2000, the outstanding balance on the bridge loan was $25.0 million and $5.0
million was available for borrowing. In total as of March 31, 2000, WorldxChange
had $46.2 million borrowed under the credit facility and $15.5 million available
for borrowing.



     In May 2000, the credit facility was amended to increase the maximum
borrowing capacity to $80.0 million. The $15.0 million increase in the borrowing
capacity consists of an additional $15.0 million under the bridge loan, under
the same terms and conditions.



     The revolving credit agreement and the term loan mature at the earlier of
60 days prior to the maturity of the subordinated promissory notes or the notes
due on the ACC Europe acquisition or October 1, 2003. As of March 31, 2000,
WorldxChange was in compliance with the restrictive covenants under the credit
facility. WorldxChange's obligations under the credit facility are secured by
first position in substantially all of its property.



     In January 2000, WorldxChange secured a $15 million loan commitment from
Gold & Appel. Any borrowings under this loan commitment will bear interest at
15% and is payable on December 31, 2000. As of March 31, 2000, WorldxChange had
no borrowings outstanding associated with this commitment.



     In fiscal 1997, WorldxChange sold a 40% interest in WorldxChange Pty. Ltd.,
its Australian operating subsidiary, to an affiliate of the Asian Infrastructure
Fund. The proceeds of approximately $9.0 million from this sale were used to
finance working capital requirements and the expansion of this operating
subsidiary. In September 1999, WorldxChange issued 1,554,763 shares of its
common stock to the Asian Infrastructure Fund in exchange for the 40% interest
in WorldxChange Pty. Ltd. The acquisition was accounted for under the purchase
method of accounting at a value of $17,102,000 or $11.00 per share.



     From May through August 1998, WorldxChange issued and sold subordinated
promissory notes in the aggregate principal amount of $55.0 million. These notes
bear interest at the rate of 12.5% per annum,


                                       144
<PAGE>   158


provide for quarterly payments of interest only and mature on November 30, 2000.
These notes provide the lender the right to require WorldxChange to use 35% of
the net proceeds from any private placement or public offering of its common
stock to repay the notes. The balance of these notes at September 30, 1999 and
March 31, 2000 was $45.2 million.



     In September 1998, WorldxChange sold 788,127 shares of its common stock in
a private placement at a price of $12.69 per share for total proceeds of $10.0
million. In December 1998, WorldxChange sold 871,087 shares of its common stock
in a private placement at a price of $11.48 per share for total proceeds of
$10.0 million. In March 1999, WorldxChange sold 3,000,000 shares of its common
stock in a private placement at a price of $10.00 per share for total proceeds
of $30.0 million. In June 1999, WorldxChange sold 2,727,270 shares of its common
stock in a private placement at a price of $11.00 per share for total proceeds
of $30.0 million. The offerings raised a total of $80.0 million. The proceeds
from these private placements were used for network expansion, to pay for direct
mail campaigns and other marketing activities, to repay subordinated debentures,
and to prepay a portion of WorldxChange's subordinated promissory notes and for
other corporate purposes.



     In August 1999, WorldxChange entered into an agreement to sell 30,000
shares of its Series A Convertible Preferred Stock in a private placement for
total proceeds of $30.0 million. These shares are convertible into 2,727,270
shares of WorldxChange's common stock. Prior to the conversion of these shares,
WorldxChange is obligated to pay the holder of these shares an annual dividend
equal to 4% of the face amount of these shares. These dividends are declared and
accrued monthly.



     WorldxChange entered into two agreements during fiscal 1999 for the
acquisition of the right to use land-based fiber optic cable systems for a total
price of $45.0 million. The vendors have agreed to finance 90% of the commitment
at 12% interest, with monthly principal and interest payments over a five year
amortization period. As of March 31, 2000, WorldxChange had acquired
approximately $37.1 million, leaving $7.9 million to be ordered.



     On November 4, 1999, WorldxChange acquired the outstanding shares of
certain European subsidiaries of ACC Corp, a subsidiary of AT&T. The operations
of these subsidiaries are located in the United Kingdom, Germany, France and
Italy. As part of this transaction, WorldxChange also acquired from ACC Corp a
switch located in the United States and certain long-term rights of use in a
transatlantic telecommunications cable system. The $113 million purchase price
for this transaction was composed of $60 million cash and a $53 million, 12% per
annum interest rate note due on or before December 28, 2000. WorldxChange
financed $50 million of the cash payment through the issuance in November 1999
of 50,000 shares of Series B Convertible Preferred Stock to two existing
shareholders for $50 million. These shares are convertible into 5,555,550 shares
of WorldxChange's common stock. Prior to the conversion of these shares,
WorldxChange is obligated to pay the holder of these shares an annual dividend
equal to 4% of the face amount of these shares. These dividends are declared and
accrued monthly.



     Prior to WorldxChange acquiring ACC Corp.'s U.K. operations, ACC
implemented a new billing system in the United Kingdom that did not function
properly, resulting in delayed billings and billings containing errors which had
to be manually corrected. The billing has been delayed as much as 75 days. This
has resulted in up to approximately $20.0 million in receivables being collected
up to 75 days later than under normal terms. Due to this delay in collections,
WorldxChange was forced to pay vendors late, negatively impacting the
relationships and requiring WorldxChange to incur late payment fees and interest
charges of approximately $500,000 with vendors. WorldxChange was able to
accurately estimate billing amounts and reflect these amounts in the applicable
quarterly operating results.



     WorldxChange believes that it will be able to satisfy its operating cash
requirements through the maturity date of its credit facility from a combination
of cash on hand, the proceeds of equity offerings, availability under
WorldxChange's vendor financing arrangements, its secured credit facility,
outstanding loan commitment and from the financing of WorldxChange's European
receivables. Under the WorldxChange merger agreement, WorldxChange will need
World Access' consent to incur debt or raise additional proceeds from equity
offerings, and there can be no assurance that any such additional debt or

                                       145
<PAGE>   159


equity proceeds can or will be raised. If the WorldxChange merger is not
completed by the maturity of the credit facility, WorldxChange will need to
raise additional capital to pay, or will need to restructure, its obligations in
connection with the ACC Europe acquisition and the subordinated promissory notes
described above. No assurance can be given that additional capital will be
raised or that such obligations can or will be restructured. The table below
summarizes WorldxChange's financial commitments as they relate to capital
expenditures, secured and unsecured loans and notes, and the credit facility.



     Below is a table summarizing capital expenditures, commitments, and debt
obligations as of March 31, 2000.

</TABLE>



MARKET RISK



     The carrying value of cash and cash equivalents approximates fair value due
to the short-term, highly liquid nature of the cash equivalents, which have
maturities of three months or less. Interest rate fluctuations would not have a
significant effect on the fair market value of cash equivalents held by
WorldxChange.



     At March 31, 2000 WorldxChange had outstanding debt, excluding capital
lease obligations, in the amount of $204.5 million, of which $183.3 million is
fixed interest debt. Variable rate debt $16.5 million carries adjustable
interest rates at the prime rate plus 1.75%, and the remaining $4.7 million
carries an adjustable rate at prime plus 5.0%. A one percent change in the
interest rate would change interest payments by approximately $17,700 per month.



FOREIGN CURRENCY EXPOSURE



     While an increasing amount of WorldxChange's revenues will be denominated
in non-U.S. currencies, a disproportionate portion of its expenditures,
including interest, will be denominated in U.S. dollars. In addition, the assets
and liabilities of WorldxChange's non-U.S. subsidiaries are generally
denominated in local currencies. Accordingly, WorldxChange may be subject to
significant foreign currency exchange risks. In addition, WorldxChange may in
the future acquire interests in entities that operate in countries where the
expatriation or conversion of currency is restricted. WorldxChange currently
does not hedge against foreign currency exchange risks, but may in the future.
Because of the number of currencies involved, WorldxChange's constantly changing
foreign currency exposure and the fact that all foreign currencies do not
fluctuate in the same manner against the U.S. dollar, WorldxChange cannot
quantify the effect of exchange rate fluctuations on its future financial
condition or results of operations.



EURO CONVERSION



     On January 1, 1999, several member countries of the European Union
established fixed conversion rates and adopted the euro as their new common
legal currency. Since that date, the euro has traded on


                                       146
<PAGE>   160


currency exchanges, although the legacy currencies will remain legal tender in
the participating countries for a transition period between January 1, 1999 and
January 1, 2002. During the transition period, parties can elect to pay for
goods and services and transact business using either the euro or a legacy
currency. Between January 1, 2002 and July 1, 2002, the participating countries
will introduce euro currency coins and withdraw all legacy currencies.



     The euro conversion may affect cross-border competition by creating
cross-border price transparency. WorldxChange is assessing its pricing and
marketing strategy in order to insure that it remains competitive in a broader
European market. In addition, WorldxChange is reviewing whether certain existing
contracts will need to be modified. WorldxChange's currency risks and risk
management for operations in participating countries may be reduced as the
legacy currencies now trade at a fixed exchange rate against the euro.
WorldxChange will continue to evaluate issues involving introduction of the
euro. However, based on current information and assessments, WorldxChange does
not expect that the euro conversion will have a material adverse effect on its
results of operations or financial condition.



SEASONALITY



     WorldxChange's European and Australian operations experience seasonality
during the summer seasons of those regions, which results in decreased customer
calling volumes.



RECENT ACCOUNTING PRONOUNCEMENTS



     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities, which establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts, and for hedging activities.
In June 1999, SFAS No. 133 was amended by SFAS No. 137, Accounting for
Derivative Instruments and Hedging Activities -- Deferral of the Effective Date
of SFAS 133. As a result of this amendment, SFAS No. 133 shall be effective for
all fiscal quarters of all fiscal years beginning after June 15, 2000. In
accordance with SFAS No. 133, an entity is required to recognize all derivatives
as either assets or liabilities in the statement of financial position and
measure those instruments at fair value. SFAS No. 133 requires that changes in
the derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allows a derivative's gain and losses to offset related results on the hedged
item in the income statement and requires that a company formally document,
designate and assess the effectiveness of transactions that receive hedge
accounting. WorldxChange does not expect the adoption of this standard to have a
material effect on its consolidated financial position or results of operations.



     On December 3, 1999, the Securities and Exchange Commission staff issued
SAB No. 101, Revenue Recognition in Financial Statements. The SAB spells out
four basic criteria that must be met before companies can record revenue. These
are: (i) persuasive evidence that an arrangement exists; (ii) delivery has
occurred or services have been rendered; (iii) the seller's price to the buyer
is fixed or determinable; and (iv) collectibility is reasonably assured. Many of
the examples in the SAB address situations that give rise to the potential for
recording revenue prematurely. They include transactions subject to
uncertainties regarding customer acceptance, including rights to refunds and
extended payment terms, and require continuing involvement by the seller.



     In March 2000, the SEC issued SAB 101A -- Amendment: Revenue Recognition in
Financial Statements, that delays the implementation date of certain provisions
of SAB 101. Management does not believe the adoption of SAB 101 would have a
material impact on WorldxChange's operations.



     In March 2000, the Financial Accounting Standards Board issued
Interpretation No. 44, Accounting for Certain Transactions Involving Stock
Compensation, an interpretation of APB Opinion No. 25. The Interpretation poses
and answers 20 separate questions dealing with APB 25 implementation practice
issues.


                                       147
<PAGE>   161


     The Interpretation will be applied prospectively to new awards,
modifications to outstanding awards, and changes in employee status on or after
July 1, 2000, except as follows: (i) requirements related to the definition of
an employee apply to new awards granted after December 15, 1998; (ii)
modifications that directly or indirectly reduce the exercise price of an award
apply to modifications made after December 15, 1998; and (iii) modifications to
add a reload feature to an award apply to modifications made after January 12,
2000. Financial statements for periods prior to July 1, 2000 will not be
affected. Management does not expect the adoption of Interpretation No. 44 to
have a material effect on its consolidated financial position or results of
operations.

(1) Cost of services is exclusive of depreciation and amortization related to
    the services network which is shown separately below.


(2) EBITDA as used in this proxy statement/prospectus is operating loss plus
    depreciation and amortization expense and is presented because WorldxChange
    believes that such information is commonly used in the telecommunications
    industry as one measure of a company's operating performance and historical
    ability to service debt. EBITDA from continuing operations is not determined
    in accordance with generally accepted accounting principles, is not
    indicative of cash provided by operating activities, should not be used as a
    measure of operating income and cash flows from operations as determined
    under generally accepted accounting principles and should not be considered
    in isolation or as an alternative to, or to be more meaningful than,
    measures of performance determined in accordance with generally accepted
    accounting principles. EBITDA, as calculated by WorldxChange, may not be
    comparable to similarly titled measures reported by other companies and
    could be misleading unless all companies and analysts calculate EBITDA in
    the same manner.

      COMPARISON OF THE RIGHTS OF HOLDERS OF WORLD ACCESS COMMON STOCK AND


                           WORLDXCHANGE COMMON STOCK



     This section of the joint proxy statement/prospectus summarizes differences
between the World Access common stock and WorldxChange common stock. These
differences arise from differences between the Delaware law and the California
law, and between the corporate charters and bylaws of World Access and
WorldxChange. WorldxChange stockholders should read the full text of each
state's corporate statute and each companies' respective corporate charters and
bylaws for a more complete understanding of the differences between World Access
common stock and WorldxChange common stock. For information on how to obtain
these documents, see "Where You Can Find More Information" on the inside front
cover page __.



     The rights of World Access' stockholders are governed by its certificate of
incorporation, as amended, its bylaws and the laws of the State of Delaware. The
rights of WorldxChange's shareholders are currently governed by its articles of
incorporation, as amended and restated, its bylaws, as amended and restated, and
California law. Upon completion of the WorldxChange merger, the WorldxChange
shareholders will become World Access stockholders, and the WorldxChange
shareholders' rights will be governed by World Access' certificate of
incorporation, as amended, its bylaws and Delaware law.



     Pursuant to the Voting and Share Transfer Restriction Agreements referred
to on page 124, the holders of WorldxChange's preferred stock have agreed to
vote in favor of the WorldxChange merger. Under the applicable certificates of
determination of preferences with respect to each series of preferred stock, if
the holder of shares of such series of preferred stock votes to approve a merger
or other business combination transaction involving WorldxChange, such holder is
deemed to have converted all of such holder's shares of such series into shares
of WorldxChange common stock immediately prior to consummation of such
transaction. Accordingly, no separate discussion of the rights of the holders of
the WorldxChange preferred stock is provided.



COMPARISON OF AUTHORIZED AND OUTSTANDING CAPITAL STOCK



     The authorized capital stock of World Access consists of 160,000,000
shares, of which 150,000,000 shares are common stock of $.01 par value per
share, and 10,000,000 shares of which are preferred stock of $.01 par value per
share. Note, however, that pursuant to this joint proxy statement/prospectus,
the World Access stockholders are being asked to approve an amendment to the
World Access certificate of incorporation which would increase the number of
shares of common stock World Access is authorized to issue to 290,000,000. As of
August 1, 2000, 61,707,277 shares of World Access common stock were outstanding,
and 584,260 shares of World Access preferred stock were outstanding.



     The authorized capital stock of WorldxChange currently consists of
110,000,000 shares, of which 100,000,000 shares shall be common stock of no par
value, and 10,000,000 shares of which shall be preferred stock of no par value.
As of August 1, 2000, 42,613,954 shares of WorldxChange common stock were
outstanding, and 30,000 shares of WorldxChange preferred stock were outstanding.



COMPARISON OF CLASSES OF COMMON STOCK



     World Access and WorldxChange each have one class of common stock issued
and outstanding. Holders of World Access common stock and holders of
WorldxChange common stock are each entitled to one vote for each share held.



COMPARISON OF REQUIREMENTS FOR SPECIAL MEETING OF SHAREHOLDERS



     Under Delaware law, special meetings of stockholders may be called by a
corporation's board of directors or such person or persons as may be authorized
by such corporation's certificate of incorporation or bylaws. World Access'
certificate of incorporation provides that special meetings of stockholders may
be called by the board of directors or by any officer instructed by the board of
directors.


                                       151
<PAGE>   165


     Under California law, a special meeting of shareholders may be called by
the board of directors, the chairman of the board, the president or the holders
of shares entitled to cast not less than 10% of the votes at such meeting or
additional persons provided in the articles or bylaws. WorldxChange's bylaws
also provide that the Chief Executive Officer may call a special meeting of
shareholders.



COMPARISONS OF REQUIREMENTS FOR ACTION BY WRITTEN CONSENT IN LIEU OF
SHAREHOLDERS' MEETING



     Under both California and Delaware law, shareholders may execute an action
by written consent in lieu of a shareholder meeting. Both California and
Delaware law permit a corporation in its charter to eliminate such actions by
written consent. Pursuant to World Access' certificate of incorporation, World
Access stockholders may not take action without a meeting by written consent
except for preferred stockholders. WorldxChange's articles of incorporation do
not eliminate shareholder actions by written consent.



     Elimination of the ability of stockholders to act by written consent could
lengthen the amount of time required to take stockholder actions, since certain
actions by written consent are not subject to the minimum notice requirement of
a stockholders' meeting. The elimination of stockholder actions by written
consents, however, could deter hostile takeover attempts. A holder or group of
holders controlling a majority interest of World Access' common stock would not
be able to amend World Access' certificate of incorporation, World Access'
bylaws or remove directors pursuant to a stockholder action by written consent,
but instead, would have to call a stockholders' meeting and observe the notice
periods determined by the World Access board pursuant to World Access' bylaws
prior to attempting to obtain approval of any such actions.



COMPARISON OF RECORD DATE FOR DETERMINING SHAREHOLDERS



     The World Access bylaws provide that the World Access board of directors
may fix a record date that:



     - in the case of determination of the stockholders entitled to vote at any
       meeting of stockholders or adjournment of any meeting, may not be more
       than 60 days or less than ten days before the date of the meeting; and



     - in the case of any other action, may not be more than 60 days before any
       to such action.



Furthermore, the World Access bylaws provide that if the World Access board of
directors does not fix a record date in the manner described above, then:



     - the record date for determining stockholders entitled to notice of or to
       vote at a meeting of stockholders will be at the close of business on the
       day next after the day that notice is given, or, if notice is waived, at
       the close of business on the day after the day that the meeting is held;
       and



     - the record date for determining stockholders for any other purpose will
       be at the close of business on the day the World Access board of
       directors adopt the related resolution.



     The WorldxChange bylaws provide that the board of directors may fix a time
in the future as a record date for the determination of the shareholders
entitled to notice of and to vote at any meeting of shareholders, to receive any
report, to receive any dividend or distribution, or any allotment of rights, or
to exercise rights in respect to any change, conversion or exchange of shares.
The record date will not be more than 60 days or less than ten days before the
date of any meeting, or more than 60 days before any other event for the
purposes of which it is fixed. When a record date is fixed, only shareholders of
record on that date are entitled to notice of and to vote at the meeting, to
receive any report, to receive a dividend, distribution or allotment of rights,
or to exercise the rights, as the case may be, notwithstanding any transfer of
any shares on the books of the corporation after the record date, except as
otherwise may be provided in the articles of incorporation or bylaws.


                                       152
<PAGE>   166


COMPARISON OF PROCEDURES TO NOMINATE DIRECTORS



     The World Access bylaws require that board nominations be made by the board
of directors or a stockholder who gives timely notice to the secretary of the
company. To give timely notice, a stockholder's nomination notice must be
received by the secretary of World Access at least 120 days before the one-year
anniversary of the date of the proxy statement in connection with the previous
year's annual meeting of stockholders. A nominating stockholder's notice must be
received by World Access no later than the close of business on the tenth day
following the earlier of:



     - the day on which notice of the upcoming meeting was mailed or given to
       the World Access stockholders; or



     - the day on which public disclosure of the date of the upcoming meeting
       was made by World Access if:



      - no annual meeting was held in the previous year;



      - the date of the upcoming annual meeting has changed by more than 30 days
        from the date set forth in the previous year's proxy statement; or



      - the upcoming meeting is not an annual meeting.



     Under WorldxChange's bylaws, at any meeting of shareholders, a person may
be a candidate for election to WorldxChange's board only if the person is
nominated:



     - by or at the direction of WorldxChange's board;



     - by any nominating committee or person appointed by WorldxChange's board;
       or



     - by a shareholder of record entitled to vote at such meeting who complies
       with certain notice procedures and has given timely notice of such
       nomination in writing to WorldxChange's secretary. To be timely, a
       shareholder's notice must be delivered to the Secretary no later than the
       close of business on the 60th day or earlier than the close of business
       on the 90th day before the meeting; provided, however, that if less than
       70 days notice of the date of the meeting is given by WorldxChange,
       notice by the shareholder to be timely must be delivered no later than
       the 10th day after the day on which public announcement of the date of
       such meeting is first made by WorldxChange.



COMPARISON OF NUMBER OF DIRECTORS



     The World Access amended certificate of incorporation and bylaws provide
that the World Access board of directors may not have less than three nor more
than 12. The exact number of directors will be determined from time to time by
the World Access board of directors. Note, however, that in connection with
joint proxy statement/prospectus, World Access is seeking approval by its
stockholders of an amendment to its certificate of incorporation that would
increase the maximum number of directors to 15.



     Under WorldxChange's articles of incorporation, the number of members of
the board of directors must be at least five, and not more than nine, unless
changed by an amendment to the articles of incorporation or by a bylaw duly
adopted by approval of the outstanding shares of WorldxChange. There are
currently seven members of WorldxChange's board of directors.



COMPARISON OF CLASSIFIED BOARD OF DIRECTORS



     Delaware law provides that a corporation may divide its board of directors
into various classes with staggered terms of office under its certificate of
incorporation or bylaws. World Access' board of directors is currently divided
into three classes, as nearly equal in size as possible, with one class being
elected annually. Directors are elected to a term of three years and until their
successors are elected and qualified. You should note that, in connection with
this joint proxy statement/prospectus, World Access is seeking the approval of
its stockholders to an amendment to the certificate of incorporation of World
Access which


                                       153
<PAGE>   167


would eliminate World Access' staggered board of directors. If this amendment is
approved, directors would be elected annually to a term of one year. At an
annual meeting in which a quorum is present, the persons receiving a plurality
of the votes cast would be elected as the directors.



     WorldxChange's board of directors is not divided into classes.



COMPARISON OF PROCEDURES FOR THE REMOVAL OF DIRECTORS



     Under Delaware law a director may be removed, with or without cause, by the
holders of a majority of the outstanding shares then entitled to vote thereon
unless (i) the corporation has a classified board of directors, in which case a
director may be removed only with cause unless the certificate of incorporation
provides otherwise, or (ii) the corporation has cumulative voting, in which
case, if less than the entire board is to be removed, no director may be removed
without cause if the number of votes cast against such removal would be
sufficient to elect the director under cumulative voting. World Access' bylaws
provide for removal of directors only for cause.



     Under California law, any director or the entire board of directors may be
removed without cause with the approval of a majority of the outstanding shares
entitled to vote thereon. However, no individual director may be removed (unless
the entire board is removed) if the number of votes cast against such removal
would be sufficient to elect the director under cumulative voting, whether or
not the corporation's articles of incorporation or bylaws do not otherwise
provide for cumulative voting. A corporation's board of directors may remove for
cause by declaring vacant the office of a director who has been (i) declared of
unsound mind by an order of court or (ii) convicted of a felony.



COMPARISON OF BOARD OF DIRECTORS VACANCIES



     Under Delaware law, vacancies and newly created directorships may be filled
by vote of a majority of the directors then in office (even though less than a
quorum), unless (i) otherwise provided in the corporation's certificate of
incorporation or bylaws, or (ii) the certificate of incorporation directs that a
particular class is to elect such director, in which case the majority of
directors elected by such class, or a sole remaining director elected by such
class, shall fill such vacancy. World Access' bylaws provide that vacancies on
the World Access 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, even if less
than a quorum, or by a sole remaining director.



     Unless otherwise provided in a corporation's articles of incorporation or
bylaws, under California law, any vacancy on a board of directors, other than
one created by removal of a director, may be filled by approval of the remainder
of the corporation's board of directors. Even if the number of remaining
directors is less than a quorum, a vacancy may be filled by the unanimous
written consent of the directors then in office or by the affirmative vote of a
majority of the directors at a meeting held pursuant to notice or waivers of
notice or by a sole remaining director. Unless the articles of incorporation or
a bylaw adopted by the shareholders provide that the board may fill vacancies
occurring in the board by reason of the removal of directors, such vacancies may
be filled only with the approval of a majority of the outstanding shares
entitled to vote thereon. WorldxChange's bylaws provide that vacancies in the
WorldxChange board of directors, except for a vacancy created by the removal of
a director, may be filled by a majority of the remaining directors, even if less
than a quorum, or by a sole remaining director. A vacancy created by the removal
of a director by the shareholders or by court order may be filled only by a vote
of the shareholders at a duly held meeting at which a quorum is present.



COMPARISON OF NOTICE REQUIREMENTS OF SPECIAL MEETINGS OF THE BOARD OF DIRECTORS



     The World Access bylaws provide that the chairman of the board, the
vice-chairman of the board, the president or a majority of directors then in
office may call special meetings of the board of directors. The bylaws do not
require a specific notice period, but only require that the notice provide
sufficient time for the convenient assembly of directors.


                                       154
<PAGE>   168


     Special meetings of the WorldxChange board of directors for any purpose or
purposes may be called at any time by the chairman of the board, the president,
any vice president or the secretary, or by any two directors, or by one or more
shareholders holding not less than 25% of any series of preferred stock of the
corporation.



     Written notice of the time and place of special meetings shall be delivered
personally to each director or communicated to each director by telephone or by
telegraph or mail, charges prepaid, addressed to him or her at his or her
address as it is shown upon the records of the corporation or, if it is not so
shown on such records or is not readily ascertainable, at the place at which
meetings of the directors are regularly held. In case such notice is mailed or
telegraphed, it shall be deposited in the United States mail or delivered to the
telegraph company in the place in which the principal executive office of the
corporation is located at least forty-eight hours prior to the time of the
holding of the meeting. In case the notice is delivered, personally or by
telephone, it be will be delivered at least twenty-four hours prior to the time
of the holding of the meeting. Such mailing, telegraphing or delivery,
personally or by telephone, as above provided, shall be due, legal and personal
notice to each such director.



COMPARISON OF PROCEDURES FOR AN AMENDMENT OF CERTIFICATE OF INCORPORATION AND
BYLAWS



     The World Access amended certificate of incorporation imposes a
super-majority voting requirement with respect to certain amendments. Any
amendment to the classified board provisions of the certificate of
incorporation, or any proposed change to the certificate or bylaws which is
inconsistent with such provision, requires the vote of holders of at least 75%
of the voting power of all shares entitled to vote in the election of directors,
voting as a single class. The World Access bylaws may be amended by the board of
directors or stockholders of World Access.



     WorldxChange's articles of incorporation requires the approval of 66 2/3%
of the combined voting power of its shareholders to amend any provisions of
Article Eight, which deals with amendments, Article Four, which deals with
cumulative voting, or Article Five, which deals with the election and term of
directors.



COMPARISON OF NOTICE REQUIREMENTS OF STOCKHOLDER'S MEETINGS



     World Access' bylaws provide that notice of a special meeting of
stockholders must be timely given in writing not less than ten days or more than
60 days before to the meeting. The notice must state the purposes for which the
meeting is called. The World Access bylaws require that board nominations be
made by the board of directors or a stockholder who gives timely notice to the
secretary of the company. To be timely, a stockholder's nomination notice must
be received by World Access at least 120 days before the one-year anniversary of
the date of the proxy statement in connection with the previous year's annual
meeting of stockholders. A nominating stockholder's notice must be received by
World Access no later than the close of business on the tenth day following the
earlier of:



     - the day on which notice of the upcoming meeting was mailed or given to
       the World Access stockholders; or



     - the day on which public disclosure of the date of the upcoming meeting
       was made by World Access if:



      - no annual meeting was held in the previous year;



      - the date of the upcoming annual meeting has changed by more than 30 days
        from the date contemplated in the previous year's proxy statement; or



      - the upcoming meeting is not an annual meeting.



     The bylaws of WorldxChange provide that upon request in writing that a
special meeting of shareholders be called for any proper purpose, notice will be
given to shareholders entitled to vote that a meeting will be held at a time
requested by the person or persons calling the meeting, not less than 35 or more
than 60 days after receipt of the request. The notice will specify the general
nature of the business to be transacted at the meeting, and no other business
may be transacted at such meeting.

COMPARISON OF STOCKHOLDER APPROVAL OF CERTAIN BUSINESS COMBINATIONS



     World Access is subject to Section 203(a) of the Delaware General
Corporation Law, which prohibits a Delaware corporation from engaging in any
business combination with any interested stockholder for a period of three years
following the time that such stockholder became an interested stockholder, with
certain exceptions, unless:



     - before such time, the board of directors of the corporation approved
       either the business combination or the transactions that resulted in the
       stockholder becoming an interested stockholder;



     - upon consummation of the transactions that 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 for purposes of determining the
       number of shares outstanding those shares owned (a) by persons who are
       directors and also officers and (b) by employee stock plans in which
       employee participants do not have the right to determine confidentially
       whether shares held subject to the plan will be tendered in a tender or
       exchange offer; or



     - at or after such time, the business combination is approved by the board
       of directors and authorized at an annual or special meeting of
       stockholders, and not by written consent, by the affirmative vote of at
       least 66 2/3% of the outstanding voting stock that is not owned by the
       interested stockholder.



     Section 203(c)(3) defines "business combinations" to include:



     - any merger or consolidation involving the corporation and (a) any
       interested stockholder, or (b) any other corporation, partnership,
       unincorporated association or other entity if the merger or consolidation
       is caused by the interested stockholder and as a result of such merger or
       consolidation, DGCL Section 203(a) is not applicable to the surviving
       entity;



     - any sale, lease, exchange, mortgage, pledge, transfer or other
       disposition of 10% or more of the assets of the corporation involving the
       interested stockholder, with certain exceptions;



     - any transaction that results in the issuance or transfer by the
       corporation of any stock of the corporation to the interested
       stockholder;



     - any transaction involving the corporation that has the effect of
       increasing the proportionate share of the stock of any class or series of
       the corporation beneficially owned by the interested stockholder; or



     - the receipt by the interested stockholder of the benefit of any loans,
       advances, guarantees, pledges or other financial benefits, with certain
       exceptions, provided by or through the corporation.



     California law requires that holders of common stock receive common stock
of the surviving company or parent company in a merger of the corporation with
the holder of more than 50% but less than 90% of the target's or its affiliate's
common stock unless all of the target company's shareholders consent to the
transaction. This provision of California law may have the effect of making a
"cash-out" merger by a majority shareholder more difficult to accomplish.
Although Delaware law does not parallel California law in this respect, under
some circumstances Section 203 provides similar protection to stockholders
against coercive two-tiered bids for a corporation in which the stockholders are
not treated equally.



COMPARISON OF INSPECTION OF SHAREHOLDER LIST



     Both Delaware and California law allow any shareholder to inspect and copy
the shareholder list for a purpose reasonably related to such person's interest
as a shareholder. Delaware law provides for inspection rights as to a list of
stockholders entitled to vote at a meeting within a ten day period preceding a
stockholders' meeting for any purpose germane to the meeting. California law
provides, in addition, for an absolute right to inspect and copy the
corporation's shareholder list by persons holding an aggregate of 5% or more of
the corporation's voting shares, or shareholders holding an aggregate of 1% or
more of such shares who have made certain filings with the Securities and
Exchange Commission.

     World Access' bylaws mirror the Delaware statutory provisions with respect
to inspection of shareholder lists. WorldxChange's bylaws mirror the California
statutory provisions with respect to inspection of shareholder lists.



COMPARISON OF DIVIDENDS AND REPURCHASES OF SHARES



     Delaware law permits a corporation to declare and pay dividends out of
surplus or, if there is no surplus, out of net profits for the fiscal year in
which the dividend is declared and/or for the preceding fiscal year as long as
the amount of capital of the corporation following the declaration and payment
of the dividend is not less than the aggregate amount of the capital represented
by the issued and outstanding stock of all classes having a preference upon the
distribution of assets. In addition, Delaware law generally provides that a
corporation may redeem or repurchase its shares only if the capital of the
corporation is not impaired and such redemption or repurchase would not impair
the capital of the corporation.



     Under California law, a corporation may not make any distribution to its
shareholders unless either:



     - the corporation's retained earnings immediately prior to the proposed
       distribution equal or exceed the amount of the proposed distribution; or



     - immediately after giving effect to such distribution, the corporation's
       assets exclusive of goodwill, capitalized research and development
       expenses and deferred charges, would be at least equal to 1 1/4 times its
       liabilities and the corporation's current assets would be at least equal
       to its current liabilities or 1 1/4 times its current liabilities if the
       average pre-tax and pre-interest expense earnings for the preceding two
       fiscal years were less than the average interest expense for such years.
       Such tests are applied to California corporations on a consolidated
       basis.



COMPARISON OF DISSOLUTION RIGHTS



     Under Delaware law, unless the board of directors approves the proposal to
dissolve, the dissolution must be unanimously approved by all the shareholders
entitled to vote thereon. Only if the dissolution is initially approved by the
board of directors may the dissolution be approved by a simple majority of the
outstanding shares of the corporation's stock entitled to vote. In the event of
such a board-initiated dissolution, Delaware law allows a Delaware corporation
to include in its certificate of incorporation a supermajority (greater than a
simple majority) voting requirement in connection with dissolutions. World
Access' amended certificate of incorporation contains no such supermajority
voting requirement.



     Under California law, shareholders holding 50% or more of the total voting
power may authorize a corporation's dissolution, with or without the approval of
the corporation's board of directors, and this right may not be modified by the
articles of incorporation.

COMPARATIVE PER SHARE MARKET PRICE DATA FOR WORLD ACCESS, STAR AND WORLDXCHANGE



     The World Access common stock is traded on the Nasdaq National Market under
the symbol "WAXS," and the STAR common stock is traded on the Nasdaq National
Market under the symbol "STRX." WorldxChange's capital stock has no established
public trading market, and therefore has no public market price.


     The following table sets forth, for the calendar quarters indicated, the
high and low sale prices per share of World Access common stock and STAR common
stock as reported on the Nasdaq National Market.

     The following table sets forth the closing prices per share of World Access
common stock and STAR common stock as reported on the Nasdaq National Market on
(i) December 20, 1999, the business day preceding public announcement that World
Access and STAR had signed a letter of intent to merge and (ii) August 1, 2000,
the last full trading day for which closing prices were available at the time of
the printing of this joint proxy statement/prospectus. This table also sets
forth the equivalent price per share of STAR common stock on those dates. The
equivalent price per share is equal to the closing price of a share of World
Access common stock on that date multiplied by .386595, the number of shares of
World Access common stock to be issued in exchange for each share of STAR common
stock, assuming no adjustment to the exchange ratio as provided for in the STAR
merger agreement in connection with the PT-1 sale.

     STAR and World Access believe that the STAR common stock presently trades
on the basis of the value of the World Access common stock expected to be issued
in exchange for the STAR common stock in the STAR merger, discounted primarily
for the uncertainties associated with the STAR merger. Apart from the publicly
disclosed information concerning World Access which is included in, or
incorporated by reference into, this joint proxy statement/prospectus, World
Access cannot state with certainty what factors account for changes in the
market price of the World Access common stock.

     STAR stockholders are advised to obtain current market quotations for World
Access common stock and STAR common stock. No assurance can be given as to the
market prices of World Access common stock or STAR common stock at any time
before the completion of the STAR merger or as to the market price of World
Access common stock at any time after the completion of the STAR merger.

     World Access and STAR have never paid cash dividends on their respective
shares of capital stock. Pursuant to the STAR merger agreement, STAR has agreed
not to pay cash dividends pending the consummation of the STAR merger without
the written consent of World Access.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS



     The following Unaudited Pro Forma Condensed Combined Financial Statements
of World Access give effect to several transactions, under seven different
scenarios, that World Access has completed or are currently contemplated as
follows:



<TABLE>
<S>            <C>                    <C>
Scenario 1:    World Access acquires  STAR, WorldxChange and TelDaFax.
Scenario 2:    World Access acquires  STAR and WorldxChange.
Scenario 3:    World Access acquires  STAR and TelDaFax.
Scenario 4:    World Access acquires  WorldxChange and TelDaFax.
Scenario 5:    World Access acquires  STAR.
Scenario 6:    World Access acquires  WorldxChange.
Scenario 7:    World Access acquires  TelDaFax.
</TABLE>



     The Unaudited Pro Forma Condensed Combined Statements of Operations for the
year ended December 31, 1999 under all three scenarios also give effect to (i)
the FaciliCom acquisition, (ii) the Comm/Net acquisition and (iii) the LDI
acquisition as if each of the acquisitions had occurred on January 1, 1999. The
Unaudited Pro Forma Condensed Combined Balance Sheets as of March 31, 2000 under
all seven scenarios gives effect to the STAR, WorldxChange and TelDaFax
acquisitions as if each acquisition had occurred on March 31, 2000. The
Unaudited Pro Forma Condensed Combined Statements of Operations for the three
months ended March 31, 2000 under all seven scenarios also give effect to the
LDI acquisitions as if the acquisition had occurred on January 1, 1999.



     On June 14, 2000, World Access entered into a definitive agreement pursuant
to which it agreed to acquire a majority share in TelDaFax in a series of
transactions. TelDaFax is a leading facilities-based provider of bundled fixed
line, wireless, Internet and e-Commerce services to business and residential
customers in Germany. Pursuant to the terms of the agreement, World Access has
agreed to buy the 33% interest in TelDaFax held by investment pools advised by
Apax Partners & Co. (the "Apax Acquisition") by issuing World Access common
stock at an exchange ratio of 1.025 shares of World Access for each share of
TelDaFax (the "Exchange Ratio"). In addition, World Access intends to make a
tender offer (the "Tender Offer") for all of the remaining shares of TelDaFax at
the Exchange Ratio. World Access also will contribute certain of its German
businesses to TelDaFax in exchange for newly issued TelDaFax shares (the
"Contribution").



     The completion of these transactions (the "Transactions") is subject to,
among other things, acquisitions by World Access in the Transactions of no less
than 50.1% of the fully diluted shares outstanding of TelDaFax on a pro forma
basis, certain regulatory approvals, including antitrust approval in Germany,
and the approval of the shareholders of World Access. The closing of the Apax
Acquisition, the Tender Offer and the Contribution will occur simultaneously.
The Transactions are anticipated to close around the end of the third quarter.
Concurrent with the Transactions, World Access intends to apply for listing on
one or more European stock exchanges, including the Neuer Market in Germany.


     The proforma 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 Condensed Combined Financial Statements represent the
preliminary determination of these adjustments based upon available information.
The total estimated purchase price of the transaction has been allocated on a
preliminary basis to assets and liabilities based on management's estimate of
their fair values. There can be no assurance that the actual adjustments will
not differ significantly from the pro forma adjustments reflected in the
Unaudited Pro Forma Condensed Combined Financial Statements.


     The Unaudited Pro Forma Condensed 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 Condensed Combined Financial Statements should be read in conjunction with
the historical consolidated financial statements of World Access, LDI, STAR,
WorldxChange and TelDaFax and the related notes thereto. See "Incorporation of
Certain Documents by Reference" and "Available Information."

STAR ADJUSTMENTS


     (1)  These columns represent the historical financial position and results
        of operations of STAR as of and for the three months ended March 31,
        2000 and for the year ended December 31, 1999 and have been adjusted to
        reflect the sale of PT-1 as required for the successful completion of
        the STAR merger. For pro forma purposes, we have assumed that the net
        cash proceeds on the sale of PT-1 will be equal to $120.0 million.

     (2)  The STAR merger will be accounted for under the purchase method of
          accounting. The total cost to acquire STAR is subject to change, to
          the extent that the number of shares of STAR common stock to be
          acquired will not be fixed until the effective date of the merger. A
          change in total cost will result in a corresponding change in goodwill
          and related amortization expense. The excess of the purchase price
          over the fair value of the net assets acquired has been allocated to
          goodwill and other intangible assets. These allocations are subject to
          change pending the completion of the final analysis of the total
          purchase price and fair values of the assets acquired and the
          liabilities assumed. The impact of such changes could be material.

            2000, approximately 22,667,000 shares of World Access Common Stock
            are assumed to have been issued in connection with the STAR merger

            In accordance with the STAR merger agreement, World Access, at its
            option, may pay up to 40% of the purchase price in the form of cash.
            Currently, World Access has no intention of paying any portion of
            the STAR purchase price with cash other than an immaterial amount to
            be paid for fractional shares and any cash to be paid for
            Dissenters' Shares. However, should World Access decide to pay a
            portion of the STAR purchase price in cash, assuming the maximum of
            40% and based upon the average closing price of World Access Common
            Stock on Nasdaq for the 10 trading day period ended July 17, 2000 of
            $10.83, World Access would be required to pay STAR shareholders
            approximately $98.2 million in cash and issue approximately 13.6
            million shares of World Access Common Stock having an approximate
            value of $171.5 million in connection with the merger. Since the
            option to pay a portion of the STAR purchase price in cash is solely
            at the option of the World Access and World Access has no intention
            of paying any portion of the STAR purchase price with the cash
            option, the pro forma balance sheets have been prepared excluding
            the cash option.

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


            (a) The average market price represents the average market price of
                World Access Common Stock for the three trading days prior to
                and on June 7, 2000, the date economic terms of the merger were
                amended.



        (ii)As the consummation of the merger is expected to occur after July
            1, 2000, we have valued the World Access options using the guidance
            in FIN 44, Accounting for Certain Transactions Involving Stock
            Compensation, an interpretation of APB Opinion No. 25. Under FIN 44,
            the fair value of vested options issued will be included as part of
            the purchase price. The fair value of unvested options issued will
            also be included as part of the purchase price; however, a portion
            of the intrinsic value (if any) of the unvested options will be
            allocated to unearned compensation and recognized as compensation
            cost over the remaining future vesting period. The intrinsic value
            to be allocated to unearned compensation is not significant and has
            not been reflected in these pro forma financial statements.



            In accordance with the merger agreement, each STAR option is to be
            converted into an option to purchase 0.3866 shares of World Access
            Common Stock. At March 31, 2000, STAR had 3,717,665 options
            outstanding; 1,774,049 of which were vested and 1,943,616 were
            unvested. The vested and unvested options are convertible to 685,847
            and 751,402 World Access options, respectively, totaling 1,437,249.



            The fair value of the 685,847 vested options is $4.4 million
            computed using the Black-Scholes Option Pricing Model and is
            included in the purchase price. The fair value of the

             CONDENSED COMBINED FINANCIAL STATEMENTS -- (CONTINUED)


            751,402 unvested options is $3.7 million computed using the
            Black-Scholes Option Pricing Model. The assumptions used in the
            Black-Scholes model are: dividend yield 0%, volatility 70%, risk
            free interest rate of 6.43%, and an expected life of 3 years.



        (iii) STAR pro forma stockholders' equity as of March 31, 2000 assumes
              the sale of PT-1 for net cash proceeds of $120.0 million.



        (iv) The pro forma goodwill is preliminary and subject to change based
             on a final review of the fair values of STAR's net assets as of the
             actual merger date. Upon a final review of the fair value of STAR's
             assets and liabilities, it is likely that certain tangible and
             intangible assets such as international licenses, foreign carrier
             operating agreements and property and equipment may be recognized
             at amounts which differ from the amounts estimated in these
             unaudited pro forma financial statements. Although we do not expect
             these final adjustments to be significant, they could increase or
             decrease the depreciation and amortization expense reflected in the
             unaudited pro forma financial statements.



        (v)  Intangible assets consist of retail customer base, licenses and
             interconnection, management and workforce expertise. Amortization
             is provided using the straight-line method over a 5-year period.

        7,826,000 shares of World Access Common Stock based upon a conversion
        rate of $11.50 per share. These shares are assumed to be issued for
        purposes of the calculation of basic and diluted earnings per share in
        the pro forma condensed combined statement of operations. The balance
        sheet adjustment reflects the conversion of approximately $77.4 million
        from accounts payable to common stock and paid-in capital for the amount
        of indebtedness outstanding as of March 31, 2000.



     (7)  Elimination of intercompany revenues and related costs.



     (8)  Adjustment for the additional tax benefit derived from certain pro
          forma adjustments. World Access has not recorded any tax benefit on a
          pro forma basis that may be derived from STAR's net operating losses.



     (9)  Represents pro forma weighted average shares for basic and diluted
          earnings from continuing operations per share. The weighted average
          shares are computed assuming the issuance of approximately 22,667,000
          shares of common stock to complete the STAR merger and 7,826,000
          shares upon the conversion of STAR indebtedness into World Access
          Common Stock, see Note 6. Due to the pro forma loss from continuing
          operations, potential common stock shares related to stock options,
          stock warrants, convertible notes and convertible preferred stock have
          been excluded from the diluted loss per share as the inclusion of
          these potential common stock shares would be anti-dilutive.

            (a) The average price represents the average market price of World
                Access Common Stock for the three trading days prior to and on
                May 23, 2000, the date economic terms of the merger were
                amended.


        (ii) As the consummation of the merger is expected to occur after July
             1, 2000, we have valued the World Access options using the guidance
             in FIN 44, Accounting for Certain Transactions Involving Stock
             Compensation, an interpretation of APB opinion No. 25. Under FIN
             44, the fair value of vested options issued will be included as
             part of the purchase price. The fair value of unvested options
             issued will also be included as part of the purchase price;
             however, a portion of the intrinsic value (if any) of the unvested
             options will be allocated to unearned compensation and recognized
             as compensation cost over the remaining future vesting period. The
             intrinsic value to be allocated to unearned compensation is not
             significant and has not been reflected in these pro forma financial
             statements.

             CONDENSED COMBINED FINANCIAL STATEMENTS -- (CONTINUED)


             In accordance with the merger agreement, each WorldxChange option
             is to be converted into an option to purchase 0.6583 shares of
             World Access Common Stock. At March 31, 2000, WorldxChange had
             3,965,531 options outstanding; 2,482,267 of which were vested and
             1,483,264 were unvested. The vested and unvested options are
             convertible to 1,634,076 and 976,433 World Access options
             respectively, totaling 2,610,509. The fair value of the 1,634,076
             vested options is $12.7 million computed using the Black-Scholes
             Option Pricing Model and is included in the purchase price. The
             fair value of the 976,433 unvested options is $5.0 million computed
             using the Black-Scholes Option Pricing Model. The assumptions used
             in the Black-Scholes model are: dividend yield 0%, volatility 70%,
             risk free interest rate of 6.43%, and an expected life of 3 years.



        (iii) As an integral component of the merger agreement, World Access
              agreed to provide WorldxChange up to $45.0 million in bridge
              funds, $25.0 million of which had been advanced as of March 31,
              2000. These funds are being used to finance operating losses
              expected to be incurred by WorldxChange prior to the merger date
              and to make permanent investments in working capital that are
              required to support WorldxChange growth. World Access expects that
              the remaining balance of $20.0 million to be advanced subsequent
              to the merger date and intends to fully forgive this loan in
              connection with the consummation of the merger. As a result, the
              bridge financing already funded is being accounted for as
              additional purchase price.



        (iv) At March 31, 2000, WorldxChange has PC based switches with net book
             value of approximately $6.5 million. The merger with World Access
             would result in an impairment of these assets, hence, the
             adjustment to write-off impaired assets from the acquisition.
             Consequently, depreciation expense is decreased by $1.3 million and
             $325,000 for the year ended December 31, 1999 and the three months
             ended March 31, 2000, respectively.



        (v) The pro forma goodwill is preliminary and subject to change based on
            a final review of the fair values of WorldxChange's net assets as of
            the actual merger date. Upon a final review of the fair value of
            WorldxChange's assets and liabilities, it is likely that certain
            tangible and intangible assets such as international licenses,
            foreign carrier operating agreements and property and equipment may
            be recognized at amounts which differ from the amounts estimated in
            these unaudited pro forma financial statements. Although we do not
            expect these final adjustments to be significant, they could
            increase or decrease the depreciation and amortization expense
            reflected in the unaudited pro forma financial statements.



        (vi) Intangible assets consist of retail customer base, management
             information systems, licenses and interconnection, management and
             workforce expertise. Amortization is provided using the
             straight-line method over a 5-year period.



     (12) Amortization of goodwill over an estimated life of 20 years. The pro
          forma adjustment to goodwill was computed as follows (in thousands):

     (13) Elimination of WorldxChange's historical goodwill.



     (14) Elimination of WorldxChange's historical shareholders' deficit
          accounts.



     (15) In connection with the consummation of the WorldxChange merger, a
          certain vendor of WorldxChange has agreed to convert approximately
          $25.0 million of WorldxChange indebtedness into approximately
          2,174,000 shares of World Access Common Stock based upon a conversion
          rate of $11.50 per share. These shares are assumed to be issued for
          purposes of the calculation of basic and diluted earnings per share in
          the pro forma condensed combined statement of operations. The balance
          sheet adjustment reflects the conversion of approximately $2.3 million
          from accounts payable to common stock and paid-in-capital for the
          amount of indebtedness outstanding as of March 31, 2000.



     (16) Elimination of intercompany carrier service revenues and related
          costs.



     (17) At March 31, 2000, WorldxChange had a $2,351,114 note payable plus
          $209,762 interest payable to STAR. Assuming the mergers of
          WorldxChange and STAR with World Access are consummated, this
          adjustment is necessary to eliminate the intercompany debt and
          interest payable.



     (18) Adjustment for the additional income tax provision derived from
          certain pro forma adjustments. World Access has not recorded any tax
          benefit on a pro forma basis that may be derived from WorldxChange's
          net operating losses.



     (19) Represents pro forma weighted average shares for basic and diluted
          earnings from continuing operations per share. The weighted average
          shares are computed assuming the issuance of an aggregate of
          29,848,000 shares issued to complete the WorldxChange merger and
          2,174,000 shares upon the conversion of WorldxChange indebtedness into
          World Access Common Stock, see Note 15. Due to the pro forma loss from
          continuing operations potential common stock shares related to stock
          options, stock warrants, convertible notes and convertible preferred
          stock have been excluded from the diluted loss per share as the
          inclusion of these potential common stock shares would be
          anti-dilutive.

TELDAFAX ADJUSTMENTS



(21) These columns represent the historical financial position and results of
     operations of TelDaFax as of and for the three months ended March 31, 2000
     and for the year ended December 31, 1999.



     The following tables represent the conversion of TelDaFax's balance sheet
     as of March 31, 2000 and statements of operations for the three months and
     year ended March 31, 2000 and December 31, 1999, respectively, from local
     currency (deutsche marks) into U.S. dollars. The U.S. dollar equivalent was
     computed by multiplying the deutsche mark balance by 0.4884, the exchange
     rate as of March 31, 2000 for the balance sheet and by 0.5048 and 0.5435
     which represent the average exchange rates for the three months and year
     ended periods March 31, 2000 and December 31, 1999, respectively.

        - Klose Share Purchase.  From June 14, 2000 until December 31, 2001, Dr.
          Henning F. Klose has a right to sell to World Access, and World Access
          has an obligation to purchase from Dr. Klose at Dr. Klose's option,
          all shares of TelDaFax stock held by Dr. Klose in up to three
          installments. From July 1, 2002 until December 31, 2002, World Access

          Vermogensverwaltung KG has a right to sell to World Access, and World

          offer, World Access will offer as consideration 1.025 shares of World
          Access Common Stock for each share of TelDaFax stock.



     The TelDaFax Purchase will be accounted for under the purchase method of
     accounting. For purposes of these pro forma financial statements, World
     Access has assumed that all five transactions were consummated resulting in
     World Access acquiring 100% of the outstanding TelDaFax shares. The total
     cost to acquire TelDaFax is subject to change, to the extent that the
     number of shares of TelDaFax capital stock to be acquired will not be fixed
     until the effective date of the merger. A change in total cost will result
     in a corresponding change in goodwill and related amortization expense. The
     excess of the purchase price over the fair value of the net assets acquired
     has been allocated to goodwill and other intangible assets. These
     allocations are subject to change pending the completion of the final
     analysis of the total purchase price and fair values of the assets acquired
     and

         days subsequent to June 14, 2000, the date economic terms of the
         purchase were announced.



     (ii) The pro forma goodwill is preliminary and subject to change based on a
          final review of the fair values of TelDaFax's net assets as of the
          actual purchase date. Upon a final review of the fair value of
          TelDaFax's assets and liabilities, it is likely that certain tangible
          and intangible assets such as customer lists, trademarks and property
          and equipment may be recognized at amounts which differ from the
          amounts estimated in these unaudited pro forma financial statements.
          Although we do not expect these final adjustments to be significant,
          they could increase or decrease the amortization and depreciation
          expense reflected in the unaudited pro forma financial statements.



     (iii) Intangible assets consist of retail customer base, licenses and
           interconnection, management and workforce expertise. Amortization is

(25) Elimination of historical shareholders' equity accounts.



(26) Elimination of intercompany service revenues and related costs.



(27) World Access has not recorded any tax benefit on a pro forma basis that may
     be derived from TelDaFax's net operating losses.



(28) Represents pro forma weighted average shares for basic and diluted earnings
     from continuing operations per share. The weighted average shares are
     computed assuming the issuance of an aggregate of 34,675,000 shares issued
     to complete the TelDaFax purchase. Due to the pro forma loss from
     continuing operations potential common stock shares related to stock
     options, stock warrants, convertible notes and convertible preferred stock
     have been excluded from the diluted loss per share as the inclusion of
     these potential common stock shares would be anti-dilutive.

(29) On December 17, 1999, World Access entered into an Asset Purchase Agreement
     with Long Distance International, Inc. ("LDI") whereby it agreed to
     purchase substantially all of its assets in exchange for World Access
     Convertible Preferred Stock, Series D, with an Aggregate Liquidation
     Preference of $185,000,000 ("World Access Preferred") and the assumption of
     certain of LDI's liabilities. At the closing of the transaction, 81% of the
     World Access Preferred was issued to holders of LDI's 12 1/4% Senior Notes
     due 2008 ("Note Holders"), in satisfaction of LDI's obligations thereunder;
     6% of World Access Preferred was issued to NETnet International S.A.
     ("S.A.") in satisfaction of LDI's obligation under an Acquisition Agreement
     dated October 9, 1998; 3% of the

             CONDENSED COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

     World Access Preferred was issued to LDI to satisfy any remaining
     obligations; and 10% of the World Access Preferred was deposited into
     escrow to secure LDI's indemnification obligations under the Asset Purchase
     Agreement. Any escrow proceeds not so applied will be allocated 70% to the
     Note Holders; 20% to S.A. and 10% to LDI.

     The Unaudited Pro Forma World Access Condensed Combined Statement of
     Operations for the year ended December 31, 1999 give effect to our February
     2000 acquisition of LDI, our December 1999 merger with FaciliCom and
     related transactions, and our May 1999 acquisition of Comm/Net as if the
     acquisitions had been completed on January 1, 1999. The Unaudited Pro Forma
     World Access Condensed Combined Statement of Operations for the three
     months ended March 31, 2000 gives effect to our February 2000 acquisition
     of LDI as if the acquisition had been completed on January 1, 2000. The
     unaudited pro forma condensed combined statements of operations, while
     helpful in illustrating characteristics of the combined company under one
     set of assumptions, does not attempt to predict or suggest future results.

     As a result of the FaciliCom merger and the restructuring program initiated
     by World Access in the fourth quarter of 1999, World Access expects to
     realize significant operational and financial synergies. These synergies
     are expected to include cost reductions resulting from traffic routing
     changes made to take advantage of each company's least cost routes,
     elimination of redundant leased line costs, elimination of redundant
     switching centers and consolidation of certain administrative functions.
     World Access currently estimates that these annualized cost savings, which
     have been excluded from the unaudited pro forma condensed combined
     statement of operations, will range from $20.0 million to $35.0 million.

     The unaudited pro forma condensed combined statements of operations are
     presented for comparative purposes only and are not intended to be
     indicative of the actual results had these transactions occurred as of the
     beginning of the period nor does it purport to indicate results which may
     be attained in the future.

     A. This column represents the historical results of operations of World
        Access. The World Access results of operations for the year ended
        December 31, 1999 includes the results of Comm/Net from May 1, 1999 and
        the results of FaciliCom from December 7, 1999. The World Access results
        of operations for the three months ended March 31, 2000 include the
        results of operations of LDI from February 11, 2000.

     B. This column represents the historical results of operations of FaciliCom
        for the period January 1, 1999 to December 6, 1999.


        On August 17, 1999 the Company entered into a definitive merger
        agreement with FaciliCom International, Inc. ("FaciliCom"), a privately
        owned company that is a facilities-based provider of European and U.S.
        originated international long-distance voice, data and Internet
        services. On December 7, 1999, the transaction was completed in its
        final form whereby FaciliCom merged into the Company (the "FaciliCom
        Merger").



        In connection with the FaciliCom Merger, the stockholders of FaciliCom
        received approximately $56.0 million in cash, 369,901 shares of
        Convertible Preferred Stock, Series C (the "Series C Preferred Stock"),
        and 495,557 vested options that each may be exercised to acquire one
        share of the Company's common stock at an average exercise price of
        $2.63 per share. In addition, the Company issued 1,912,500 non-qualified
        options to purchase Company common stock at an exercise price of $15.00
        per share in exchange for substantially all the options held by
        FaciliCom's employees. The Series C Preferred Stock which has a $369.9
        million liquidation preference was valued at $265.5 million based on its
        estimated market value as of the FaciliCom Stock Valuation Date, as
        determined by an investment banking firm. The stock options were valued
        at $24.8 million based on the Black-Scholes option valuation model.
        Included in other liabilities in the table below, is $300.0 million
        10 1/2% FaciliCom Series B Senior Notes due 2008 which were exchanged
        for the Company's 13.25% Senior Notes due 2008 having an aggregate
        principal amount of $300.0 million. As consideration for this exchange
        the Company issued 942,627 shares of its common stock valued at $15.0
        million to FaciliCom noteholders.



        The Series C Preferred Stock bears no dividend and is convertible into
        shares of the Company's common stock at a conversion rate of $20.38 per
        common share, subject to adjustment in the event of below market
        issuances of common stock, stock dividends, subdivisions, combinations,
        reclassifications and other distributions with respect to common stock.
        If the closing trading price of the Company's common stock exceeds
        $20.38 per share for 60 consecutive trading days, the Series C Preferred
        Stock will automatically convert into common stock. Initially, the
        holders of the Series C Preferred Stock were entitled to elect four new
        directors to the Company's board of directors. Except for the election
        of directors, the holders of the Series C Preferred Stock vote on an
        as-converted basis with the holders of the Company's common stock.



        The acquisition of FaciliCom has been accounted for using the purchase
        method of accounting. Accordingly, the results of FaciliCom's operations
        have been included in the accompanying consolidated financial statements
        from December 7, 1999. The excess of purchase price over the

     C. This column represents the historical results of operations of Comm/Net
        for the period January 1, 1999 to April 30, 1999.


        In May 1999, the Company acquired substantially all the assets and
        assumed certain liabilities of Comm/Net Holding Corporation and its
        wholly owned subsidiaries, Enhanced Communications Corporation, Comm/Net
        Services Corporation and Long Distance Exchange Corporation (Comm/Net
        Holdings and its wholly owned subsidiaries are collectively referred to
        herein as "Comm/Net"). Comm/Net, headquartered in Plano, Texas, is a
        facilities-based provider of wholesale international long distance and
        wholesale prepaid calling card services, primarily to the Mexican
        telecommunications markets.



        In connection with the acquisition, the Company issued 23,174 shares of
        4.25% Cumulative Junior Convertible Preferred Stock, Series B (the
        "Series B Preferred Stock"), valued at approximately $18.5 million with
        a $23.2 million liquidation preference, and paid approximately $3.5
        million to retire certain Comm/Net notes payable outstanding at the time
        of acquisition. The Series B Preferred Stock is convertible into shares
        of the Company's common stock at a conversion rate of $16.00 per common
        share, subject to standard anti-dilution adjustments. If the closing
        trading price of the Company's common stock exceeds $16.00 per share for
        45 consecutive trading days, the Series B Preferred Stock will
        automatically convert into common stock. Preferred dividends began
        accruing July 1, 1999 and are payable quarterly. In March 2000, the
        Series B Preferred Stock was converted into 1,448,373 shares of the
        Company's common stock.



        The acquisition of Comm/Net has been accounted for under the purchase
        method of accounting. Accordingly, the results of Comm/Net's operations

            (i) World Access management has determined the fair value of the
       185,000 shares of Series D Preferred Stock issued as part of the LDI
       merger consideration to be $217,560 or $1,176 per share. The fair value

       stock into which the preferred shares are convertible multiplied by the
       average market price of the common stock for three trading days prior and
       the three trading days subsequent to the date economic terms of the
       acquisition are announced, and then adding a six percent premium to the
       value to reflect the preferred stock preferences over common stock. The

       Stock bears no dividend and is convertible into shares of World Access
       Common Stock at a conversion rate of $18 per common share of World Access

       World Access common stock. If the closing trading price of World Access

       following assumptions: dividend yield 0%, volatility 70%, risk free
       interest rate of 6.3% and an expected life of 4 years. The World Access
       options have an exercise price of $18.50 per share. The holders of the

     K.  Adjustment for the additional tax benefit derived from certain pro

         operating losses.

     L.  To increase preferred stock dividends to reflect the Series B preferred
         stock issued in connection with the Comm/Net acquisition as outstanding

     N.  Represents pro forma weighted average shares and basic diluted earnings
         from continuing operations per share for the year ended December 31,
         1999. The weighted average shares are computed assuming the issuance of
         (1) an aggregate of 4,713,128 shares issued for $75.0 million in
         connection with the private placement of World Access common stock in
         conjunction with the FaciliCom merger; (2) an aggregate of 942,627
         shares issued to the holders of the FaciliCom notes; (3) an aggregate
         963,722 shares issued to certain FaciliCom shareholders; and (4)
         7,500,000 shares released from escrow related to the acceleration of
         the Resurgens earn-out in connection with the FaciliCom merger as of
         January 1, 1999. Due to the pro forma loss from continuing operations
         potential common stock shares related to stock options, stock warrants,
         convertible notes and convertible preferred stock have been excluded
         from the diluted loss per share as the inclusion of these potential
         common stock shares would be anti-dilutive.

         For the three months ended March 31, 2000, no additional shares of
         common stock are deemed to be outstanding. Due to the pro forma loss
         from continuing operations potential common stock shares related to
         stock options, stock warrants, convertible notes and convertible
         preferred stock have been excluded from the diluted loss per share as
         the inclusion of these potential common shares would be anti-dilutive.


     O.  In April 2000, the Company sold its Telco Systems division to BATM
         Advanced Communications Limited, an Israel-based technology company,
         for $260.8 million of cash and 960,000 restricted shares of BATM common
         stock. The shares of BATM common stock, which had an initial value of
         approximately $70.0 million, trade on the London Stock Exchange. Under
         the terms of the definitive agreement, the Company may not sell,
         transfer or otherwise monetize these shares for a period of one year
         without the consent of BATM. Cash proceeds have been adjusted for the
         estimated taxes payable on the gain realized and other fees and
         expenses relating to the sale.

         Under the terms of the Indenture governing World Access' $300.0 million
         of 13.25% Senior Notes due 2008, World Access has an obligation to
         utilize the net cash proceeds from the sale of certain of the Company's
         equipment businesses to make a one-time tender offer for all or a
         portion of the 13.25% Senior Notes outstanding. Based on transactions
         completed as of the date of this joint proxy statement/prospectus, the
         Company is currently obligated to tender for approximately $160.0
         million of the 13.25% Senior Notes by January 2, 2001. The pro forma
         financial statements do not include the impact, if any, of the tender
         offer on the financial position of World Access.

                       MANAGEMENT OF THE COMBINED COMPANY


EXECUTIVE OFFICERS


     Following the consummation of the STAR merger and/or the WorldxChange
merger, John D. Phillips will serve as Chairman of the Board and Chief Executive
Officer of the combined company, and Walter J. Burmeister will serve as the
President of the combined company. It is anticipated that the other current
executive officers of World Access will continue as executive officers of the
combined company with the duties and responsibilities they currently have at
World Access. At the time of mailing this joint proxy statement/prospectus, the
companies have not yet determined which specific offices will be held by the
current executive officers of STAR and WorldxChange.


BOARD OF DIRECTORS


     The board of directors of World Access currently consists of 11 members,
seven of which are elected by the World Access common stockholders and four of
which are nominated and elected by the Series C preferred stockholders. Upon the
completion of the STAR merger and/or the WorldxChange merger, pursuant to the
terms of the World Access Certificate of Designation of the Series C preferred
stock, due to the decreased percentage of the total outstanding World Access
common stock represented by the number of shares of World Access common stock
issuable upon conversion of the Series C preferred stock, the Series C preferred
stockholders will be entitled to designate only two directors.



     The current directors of World Access elected by common stockholders are:
Stephen J. Clearman, John P. Imlay, Jr., Massimo Prelz Oltramonti, John D.
Phillips, John P. Rigas, Carl E. Sanders and Lawrence C. Tucker. The current
directors of World Access designated by the Series C preferred stockholders are:
Walter J. Burmeister, Kirby J. Campbell, Bryan Cipoletti and Dru A. Sedwick. In
connection with the completion of the STAR and/or WorldxChange mergers, two of
the current directors of World Access designated by the Series C preferred
stockholders will no longer serve on the World Access board. As of the date of
this joint proxy statement/prospectus, the two directors whose terms will end
upon completion of the STAR and/or WorldxChange mergers have not been
determined.



     Under the terms of the STAR merger agreement, World Access agreed to elect
Christopher Edgecomb, or such other person designated by STAR and agreed to by
World Access, to the board of directors of World Access immediately following
completion of the STAR merger. Under the terms of the WorldxChange merger
agreement, World Access agreed to elect one designee of WorldxChange to the
World Access board of directors immediately following completion of the
WorldxChange merger. The WorldxChange merger agreement provides that this
designee will be Walter Anderson, who is currently the Chairman of the Board of
WorldxChange, or another person designated by Gold & Appel Transfer S.A. and
reasonably acceptable to World Access. Mr. Anderson has the power to direct such
designation by Gold & Appel Transfer S.A. As of the date of this joint proxy
statement/prospectus, the director designees of STAR and WorldxChange have not
been determined.



                   RECENT DEVELOPMENTS INVOLVING WORLD ACCESS



     The board of directors of World Access has approved a Purchase and Transfer
Agreement, dated as of June 14, 2000, under which World Access will acquire
shares of TelDaFax stock.



     Pursuant to the TelDaFax Purchase Agreement, World Access will acquire
shares of TelDaFax in five transactions:



     - Contribution.  TelDaFax and Netnet Telekommunications GmbH and NewTel
       Communications GmbH, each a subsidiary of World Access, will enter into a
       Contribution/Exchange Agreement under which World Access will contribute
       the German operations of Netnet and NewTel to TelDaFax in exchange for
       newly issued shares of TelDaFax;



     - Funds Share Purchase.  Apax Germany II L.P., Apax Funds Nominees Ltd. fur
       "B" Account, Apax Funds Nominees Ltd. fur "D" Account and AP
       Vermogensverwaltung Gesellschaft

                                       207
<PAGE>   221


       burgerlichen Rechts, collectively referred to as the Funds, have agreed
       to sell all of the TelDaFax shares held by them to World Access. In the
       purchase of the TelDaFax shares from the Funds, each share of TelDaFax
       stock will be exchanged for 1.025 shares of World Access common stock;



     - Klose Share Purchase.  From June 14, 2000 until December 31, 2001, Dr.
       Henning F. Klose has a right to sell to World Access, and World Access
       has an obligation to purchase from Dr. Klose at Dr. Klose's option, all
       shares of TelDaFax stock held by Dr. Klose in up to three installments.
       From July 1, 2002 until December 31, 2002, World Access has a right to
       purchase from Dr. Klose, and Dr. Klose has an obligation to sell to World
       Access at World Access' option, all shares of TelDaFax stock held by Dr.
       Klose. In the Klose share purchase, each share of TelDaFax stock will be
       exchanged for 1.025 shares of World Access common stock;



     - A+M Share Purchase.  From the closing of World Access' purchase of the
       TelDaFax shares held by the Funds until April 30, 2001, A+M GmbH & Co
       Vermogensverwaltung KG has a right to sell to World Access, and World
       Access has an obligation to purchase from A+M at A+M's option, all shares
       of TelDaFax stock held by A+M. From July 1, 2000 until December 31, 2001,
       World Access has a right to purchase from A+M, and A+M has an obligation
       to sell to World Access at World Access' option, all shares of TelDaFax
       stock held by A+M. In the A+M share purchase, each share of TelDaFax
       stock will be exchanged for 1.025 shares of World Access common stock;
       and



     - Tender Offer.  World Access will conduct a tender offer for all of the
       issued and outstanding shares of TelDaFax. In the tender offer, World
       Access will offer as consideration 1.025 shares of World Access common
       stock for each share of TelDaFax stock.



     The TelDaFax transactions require the approval of a majority in voting
power of the shares of World Access common stock, World Access Series A
preferred stock, World Access Series C preferred stock, World Access Series D
preferred stock and World Access Series E preferred stock entitled to vote and
voting as a single class. The World Access stockholders will consider and vote
on the TelDaFax transactions at a separate special meeting. In connection with
this meeting, World Access will file a separate registration statement with the
Securities and Exchange Commission containing a proxy statement describing the
TelDaFax transactions.



                                   PROPOSAL 4



              AMENDMENT OF THE WORLD ACCESS AMENDED CERTIFICATE OF


                 INCORPORATION TO INCREASE THE NUMBER OF SHARES


             OF COMMON STOCK THAT WORLD ACCESS IS ENTITLED TO ISSUE


                 FROM 150,000,000 SHARES TO 290,000,000 SHARES



     Currently, World Access does not have a sufficient number of shares of
common stock authorized for issuance under its amended certificate of
incorporation to complete both the STAR merger and the WorldxChange merger.
Although neither the STAR merger agreement nor the WorldxChange merger agreement
condition the closing of the mergers on stockholder approval of an increase in
authorized shares. However, if the World Access stockholders do not approve an
increase in the authorized shares, World Access' management will determine with
which merger World Access will proceed with or if an alternative structure for
one of the mergers is feasible.



     The World Access board of directors has adopted a resolution unanimously
approving and recommending to the World Access stockholders for their approval
an amendment to Article IV of World Access' amended certificate of incorporation
to provide therein for an increase in the number of shares of common stock
authorized for issuance from 150,000,000 shares to 290,000,000 shares. World
Access' authorized common stock currently consists of 150,000,000 shares of
common stock, $.01 par value per share, of which 60,101,658 were issued and
outstanding as of May 22, 2000 and approximately 46,006,000 were reserved for
issuance upon conversion of Series A preferred stock, Series C preferred stock
and Series D preferred stock, upon the conversion of Series A preferred stock
underlying options for such stock

                                       208
<PAGE>   222


and upon exercise of options and warrants granted under World Access' stock
option plans and director warrant plans. Accordingly, as of May 22, 2000, World
Access had available for issuance approximately 43.9 million shares of common
stock. Upon completion of the STAR merger, World Access will issue approximately
22.9 million shares of World Access common stock as consideration to the STAR
stockholders. Upon completion of the WorldxChange merger, World Access will
issue approximately 29.8 million shares of World Access common stock as
consideration to the WorldxChange shareholders.



     The World Access board of directors believes the increase in the number of
shares of common stock authorized for issuance is desirable to enhance our
flexibility in connection with possible future actions, such as public or
private offerings of shares for cash, dividends payable in our stock, corporate
mergers and acquisitions, and implementation and continuation of employee
benefit plans. Having additional authorized shares for issuance in the future
would allow shares of common stock to be issued without the expense and delay of
a special meeting of stockholders. The additional shares of common stock may be
voting or non-voting as determined in the board's sole discretion with no
further authorization by security holders required for the creation and issuance
thereof, subject to the requirements of the Nasdaq National Market that
stockholder approval be obtained for certain issuances of additional shares of
common stock in excess of 20% of the number of shares then outstanding. In
addition, if World Access issued a new series of common stock or any preferred
stock that disparately reduced the voting rights of the World Access common
stock, then the World Access common stock could be excluded from the Nasdaq
National Market. The terms of any new series of common stock or any preferred
stock subject to this proposal cannot be stated or estimated at this time.



     The World Access board of directors is not proposing the increase in the
authorized number of shares of common stock with the intention of using the
shares for anti-takeover purposes. However, it is possible that the issuance of
additional shares of common stock authorized by this Proposal 4 may render more
difficult or discourage a merger, tender offer or proxy contest involving World
Access, the assumption of control of World Access by the holder of a large block
of the common stock or the removal of incumbent management. For example, the
issuance of additional shares of common stock could discourage a potential
acquiror by:



     - increasing the number of shares of common stock necessary to gain control
       of World Access;



     - permitting World Access, through the public or private issuance of shares
       of common stock, to dilute the stock ownership of a potential acquiror;
       or



     - permitting World Access to privately place shares of common stock with
       purchasers who side with the board of directors in opposing a takeover
       bid.



     Except for the proposed issuance in connection with the TelDaFax
transaction, World Access does not have any current plans, agreements or
understandings under which any of the additional shares of common stock to be
authorized would be issued.



     Approval of this Proposal 4 requires the affirmative vote of a majority in
voting power of the outstanding shares of World Access common stock, Series A
preferred stock, Series C preferred stock, Series D preferred stock and Series E
preferred stock voting as a single class, and a majority of the outstanding
shares of World Access common stock voting as a single class. If approved by the
World Access stockholders, the amendment to the amended certificate of
incorporation will become effective upon filing with the Secretary of the State
of Delaware a certificate of amendment to our amended certificate of
incorporation, which filing is expected to take place shortly after the World
Access special meeting.



THE WORLD ACCESS BOARD OF DIRECTORS RECOMMENDS THAT THE WORLD ACCESS
STOCKHOLDERS VOTE FOR THE AMENDMENT TO THE WORLD ACCESS AMENDED CERTIFICATE OF
INCORPORATION TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK AUTHORIZED FOR
ISSUANCE FROM 150,000,000 SHARES TO 290,000,000 SHARES.

                                   PROPOSAL 5



               AMENDMENT OF THE WORLD ACCESS AMENDED CERTIFICATE


                   OF INCORPORATION TO INCREASE THE NUMBER OF


                       AUTHORIZED DIRECTORS FROM 12 TO 15



     The World Access board of directors has adopted a resolution unanimously
approving and recommending to the stockholders for their approval an amendment
to Article IX of the World Access amended certificate of incorporation to
increase the number of authorized directors from 12 to 15.


     Article IX of the World Access amended certificate of incorporation
currently provides that the World Access board of directors shall consist of not
fewer than three members and not more than 12 members. The exact number of
authorized directors within this range may be fixed from time to time by a
resolution of the World Access board. The World Access board of directors
believes an increase in the maximum number of directors from 12 to 15 will
provide it greater flexibility in determining the board's composition.


     Approval of this Proposal 5 requires the affirmative vote of at least 75%
in voting power of the outstanding shares of World Access common stock, Series A
preferred stock, Series C preferred stock, Series D preferred stock and Series E
preferred stock entitled to vote and voting as a single class. If approved by
the World Access stockholders, the amendment to the amended certificate of
incorporation will become effective upon filing with the Secretary of State of
Delaware a certificate of amendment to the World Access amended certificate of
incorporation, which filing is expected to take place shortly after the World
Access special meeting.



THE WORLD ACCESS BOARD OF DIRECTORS RECOMMENDS THAT THE WORLD ACCESS
STOCKHOLDERS VOTE FOR THE AMENDMENT TO THE WORLD ACCESS AMENDED CERTIFICATE OF
INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED DIRECTORS FROM 12 TO 15.

     The World Access board of directors has adopted a resolution unanimously
approving and recommending to the stockholders for their approval an amendment
to Article IX of the World Access amended certificate of incorporation to end
the classification of the World Access board of directors.



     Article IX of the World Access amended certificate of incorporation
currently provides for the division of the board of directors into three classes
with each serving staggered three year terms. The purpose of dividing the
directors into three classes was to promote continuity and stability in our
management and policies by making an attempted takeover of World Access more
difficult. A classified board of directors extends the time required to make a
change in control of the board and tends to discourage any hostile takeover
because it takes at least two annual meetings to make a change in control of the
board, since only a minority of the directors are elected at each meeting.



     The World Access board of directors believes that the elimination of the
classified board will allow World Access stockholders to express their views
annually regarding the board in its entirety by electing all directors annually
and also help to ensure that each director will represent the interest of all
stockholders. Further, the elimination of the classified board promotes greater
accountability by all directors each year and encourages directors to better
serve stockholders while discouraging preserving the status quo. Because there
is no limit to the number of terms an individual may serve, the continuity and
stability of the World Access board's membership and our policies and long-term
strategic planning should not be affected. Although eliminating the
classification of the World Access board may increase the risk of a hostile


                                       210

takeover, World Access' management believes the benefits of eliminating the
classification of the board provides greater potential for value to
shareholders. Further, as World Access seeks to acquire new businesses, it may,
from time to time, grant board nominees to acquired companies, for which shorter
terms are beneficial. If this proposal is approved, World Access directors will
be elected for and will serve one year terms until their successors are duly
elected and qualified or until the earlier of their death, resignation or
removal. The amendment to the World Access certificate of incorporation to
eliminate the classified board would not shorten the terms of directors elected
or appointed prior to it becoming effective. The new procedure would, however,
apply to all World Access directors as their terms expire.



     Approval of this Proposal 6 requires the affirmative vote of at least 75%
in voting power of the outstanding shares of World Access common stock, Series A
preferred stock, Series C preferred stock, Series D preferred stock and Series E
preferred stock entitled to vote and voting as a single class. If approved by
the World Access stockholders, the amendment to the amended certificate of
incorporation will become effective upon filing with the Secretary of State of
Delaware a certificate of amendment to the World Access amended certificate of
incorporation, which filing is expected to take place shortly after the World
Access special meeting.



THE WORLD ACCESS BOARD OF DIRECTORS RECOMMENDS THAT THE WORLD ACCESS
STOCKHOLDERS VOTE FOR THE AMENDMENT TO THE WORLD ACCESS AMENDED CERTIFICATE OF
INCORPORATION TO END THE CLASSIFICATION OF THE WORLD ACCESS BOARD OF DIRECTORS
SO THAT ALL DIRECTORS WILL SERVE TERMS OF ONE YEAR AND UNTIL THEIR SUCCESSORS
ARE DULY ELECTED AND QUALIFIED.

                                   PROPOSAL 7



AMENDMENT TO THE WORLD ACCESS DIRECTORS' WARRANT INCENTIVE PLAN TO INCREASE THE
 NUMBER OF WARRANTS ISSUABLE UNDER THE PLAN FROM 600,000 WARRANTS TO 1,200,000
                                    WARRANTS



     In December 1994, in an effort to attract and retain the best available
personnel to serve on its board of directors, World Access established the World
Access, Inc. Directors' Warrant Incentive Plan. Other purposes of the Warrant
Plan are to provide additional incentive to the persons serving as World Access
directors, to encourage their continued service on the World Access board, and
to align director and stockholder long-term incentives. World Access directors
currently receive no cash compensation.



     The Warrant Plan also represents a source of equity capital to World Access
in that directors are required to pay the warrant exercise price in the form of
cash. In addition, warrants issued under the Warrant Plan are non-qualified for
federal income tax purposes. This tax treatment is intended to provide World
Access income tax deductions equal to the difference between the aggregate
market value and aggregate exercise price of the warrants on the dates of
exercise.



DESCRIPTION OF PROPOSED AMENDMENT



     The aggregate number of shares of World Access common stock currently
authorized for issuance pursuant to the Warrant Plan is 600,000. As of August 1,
2000, 450,000 shares available under the Warrant Plan had been issued or were
contingently issuable upon the exercise of outstanding warrants. To date, all
warrants under the Warrant Plan have been granted only to outside directors of
the board. On April 25, 2000, the World Access board approved, subject to and
effective upon stockholder approval, an amendment to the Warrant Plan that would
authorize an additional 600,000 shares of World Access common stock for issuance
under the Warrant Plan, so that the total shares authorized for the Warrant Plan
will be 1,200,000 shares. If the proposed amendment is approved by the World
Access stockholders, this change will be effective as of April 25, 2000.



     World Access believes that the increase in the authorized shares under the
Warrant Plan is in the best interests of all stockholders and will further the
purposes of the Warrant Plan. The number of authorized shares has not been
increased since the Warrant Plan was initially adopted in December 1994. World
Access has grown significantly since that time and is forecasting significant
additional growth during the next few years. The increase in the number of
authorized shares will provide World Access with 750,000 shares available for
future issuance under the Warrant Plan. With five elected outside directors
currently serving on the World Access board of directors, these shares would
allow for three years of potential grants, assuming the performance criteria
under the Warrant Plan is met in each year.



BRIEF SUMMARY OF THE WARRANT PLAN


     The Warrant Plan provides that each member of the World Access board may be
granted on an annual basis, in the discretion of the World Access board,
warrants to purchase up to 50,000 shares of World Access common stock in the
aggregate. However, no warrants may be granted under the Warrant Plan during
1999 and thereafter unless the fair market value of the World Access common
stock has increased a certain amount over the previous four years. The shares
may be authorized, but unissued, reacquired or forfeited shares of World Access
common stock. Each warrant will have a five-year term. The initial exercise
price of the warrants granted under the Warrant Plan shall be 110% of the fair
market value of the World Access common stock on the date of grant. World Access
must, at all times, keep available and reserve a number of shares sufficient to
satisfy the Warrant Plan's requirements.

     The warrants shall become exercisable in one or more installments as the
World Access board may determine, but if a director has not attended at least
75% of the meetings of the World Access board for the year in which an
installment first becomes exercisable, then such installment will not become
exercisable at that time. Generally, no warrant shall be exercisable within the
first six months of its term. The warrants are exercisable only while the World
Access board member remains a member of the board, and for 60 days thereafter.
This exercise period is extended to three months if the termination of service
is

                                       212
<PAGE>   226

due to a total and permanent disability. Generally, the exercise period is
extended to six months following a non-employee director's death if death occurs
while still a director, and the portion of the warrant exercisable is determined
as if the director had lived and continued service as a director for an
additional six months. If death occurs during the three months following
termination of service as a director, the warrant may be exercised during the
six months following death, but only to the extent that it had accrued at the
date of termination. Payment of the exercise price may be made in cash or check
or any combination thereof. Warrants generally may not be transferred other than
by will or by the laws of descent or distribution, or pursuant to a qualified
domestic relations order. However, the World Access board may, in its
discretion, authorize transfer to the spouse, children, or grandchildren of the
warrant holder, to a trust for such family members, to a partnership of which
such family members are the only partners, or to a charitable organization,
under certain circumstances.


     The World Access board shall adjust the number of shares of World Access
common stock available for issuance under the Warrant Plan as well as the price
per share of World Access common stock covered by each outstanding warrant
proportionately for any increase or decrease in the number of issued shares of
World Access common stock resulting from a stock split, reverse stock split,
stock dividend, combination or reclassification of the World Access common
stock, or any other increase or decrease in the number of issued shares of World
Access common stock effected without receipt of consideration by World Access
(not including the conversion of convertible securities or the issuance by World
Access of stock or convertible securities). Warrants to be issued pursuant to
the Warrant Plan will become immediately exercisable:



     - if World Access is to be consolidated with or acquired by another entity
       in a merger;



     - upon the sale of substantially all of World Access's assets or the sale
       of at least 90% of the outstanding World Access common stock to a third
       party;



     - upon the merger or consolidation of World Access with or into any other
       corporation or the merger or consolidation of any corporation with or
       into World Access in which consolidation or merger the stockholders of
       World Access receive distributions of cash or securities; or



     - upon the liquidation or dissolution of World Access.


     The World Access board has authority to:


     - determine, upon review of relevant information and in accordance with the
       Warrant Plan, the fair market value of the World Access common stock;



     - interpret the Warrant Plan;



     - prescribe, amend and rescind rules and regulations relating to the
       Warrant Plan;



     - authorize any person to execute on behalf of World Access any instrument
       required to effectuate the grant of a warrant previously granted under
       the Warrant Plan; and



     - make all other determinations deemed necessary or advisable for the
       administration of the Warrant Plan.


     All World Access board determinations will be final and binding on all
holders of warrants.

     A warrant may be suspended or terminated if the Chief Executive Officer of
World Access reasonably believes that the warrant holder has committed an act of
misconduct. If the World Access board (excluding the relevant warrant holder)
determines that the warrant holder has committed an act of embezzlement, fraud,
dishonesty, nonpayment of an obligation owed to World Access, breach of
fiduciary duty or deliberate disregard of World Access rules resulting in loss,
damage or injury to World Access, or if the warrant holder makes unauthorized
disclosure of any World Access trade secret or confidential information, engages
in unfair competition, induces any World Access customer to breach a contract
with World Access, or induces any principal for whom World Access acts as agent
to terminate such agency relationship, such warrant holder shall not be entitled
to exercise any warrant.

     The Warrant Plan will continue in effect until December 2004, unless
earlier terminated by the World Access board. The World Access board may amend
or terminate the Warrant Plan at any time, provided

                                       213
<PAGE>   227

any such amendment or termination will not affect previously granted warrants,
unless otherwise agreed in writing between World Access and the holder of the
warrant.


     As of August 1, 2000, there were 350,000 warrants issued and outstanding
under the Warrant Plan at exercise prices ranging from $8.25 to $25.85 per
share, all of which were exercisable. As of August 1, 2000, 100,000 warrants
have been exercised under the Warrant Plan. Current directors of World Access
have been granted warrants to acquire the following number of shares of Common
Stock under the Warrant Plan: Mr. Clearman - 150,000; Mr. Imlay - 50,000; Mr.
Phillips - 100,000; and Mr. Sanders - 50,000.


     Federal Income Tax Consequences.  Neither World Access nor the warrant
holder has income tax consequences from the grant of warrants under the Warrant
Plan. Generally, in the tax year when the holder exercises a warrant, the
warrant holder recognizes ordinary income in the amount by which the fair market
value of the shares at the time of exercise exceeds the exercise price for the
warrants. World Access will generally have a deduction in the same amount as the
ordinary income recognized by the warrant holder in World Access' tax year in
which or with which the warrant holder's tax year (of exercise) ends.

VOTE REQUIRED


     Approval of this Proposal 7 requires the affirmative vote of a majority in
voting power of the outstanding shares of World Access common stock, Series A
preferred stock, Series C preferred stock, Series D preferred stock and Series E
preferred stock, voting as a single class. If approved by the World Access
stockholders, the amendment to the Warrant Plan will become effective upon such
approval.



THE WORLD ACCESS BOARD OF DIRECTORS RECOMMENDS THAT THE WORLD ACCESS
STOCKHOLDERS VOTE FOR THE AMENDMENT TO THE WORLD ACCESS DIRECTORS' WARRANT
INCENTIVE PLAN TO INCREASE THE NUMBER OF WARRANTS ISSUABLE UNDER THE PLAN FROM
600,000 WARRANTS TO 1,200,000 WARRANTS.



                                   PROPOSAL 8



        AMENDMENT TO THE WORLD ACCESS DIRECTORS' WARRANT INCENTIVE PLAN


               TO CHANGE THE PERFORMANCE CRITERIA UNDER THE PLAN



     On April 25, 2000, the World Access board approved, subject to and
effective upon stockholder approval, an amendment to the Warrant Plan that would
change the performance criteria of the World Access common stock under the
Warrant Plan. If the proposed amendment is approved by the World Access
stockholders, this change will be effective as of April 25, 2000. The previous
performance criteria dates back to the inception of the Warrant Plan in December
1994 when World Access common stock traded at $1.25 per share.



     Under the current provisions of the Warrant Plan, no warrants may be
granted for a year unless the price of World Access common stock has increased
by a compounded average annual growth rate equal to or in excess of 35% for the
four years preceding the year of grant. The proposed amendment would decrease
the period over which the growth rate of World Access common stock is to be
measured to determine whether warrants may be granted for a particular year.
Under the proposed amendment, beginning in February 2001, the growth rate of the
price of World Access common stock will be measured over the previous two years
rather than the previous four years. In addition, the stock price must have
grown by a compounded average annual growth rate equal to or in excess of 10%
over the measurement period, rather than 35%, in order for the World Access
board to grant warrants under the Warrant Plan.



     World Access believes that the decrease in the measurement period for the
growth rate of World Access common stock for the determination of whether
warrants may be granted is in the best interests of all stockholders and will
further the purposes of the Warrant Plan. The target price to determine
eligibility in February 2001 is approximately $26.00 under both the previous and
proposed performance criteria. The proposed revisions to the performance
criteria were designed to address the fact that the previous criteria


                                       214
<PAGE>   228


requires a target price of more than $60.00 per share in February 2002. Warrants
issued under the Warrant Plan represent the only form of ongoing consideration
paid to outside directors. As a result, World Access believes the performance
criteria defined under this Warrant Plan must be reasonably defined to assist
World Access in attracting and retaining highly qualified outside directors.



VOTE REQUIRED



     Approval of this Proposal 8 requires the affirmative vote of a majority in
voting power of the outstanding shares of World Access common stock, Series A
preferred stock, Series C preferred stock, Series D preferred stock and Series E
preferred stock, voting as a single class. If approved by the World Access
stockholders, the amendment to the Warrant Plan will become effective upon such
approval.



     THE WORLD ACCESS BOARD OF DIRECTORS RECOMMENDS THAT THE WORLD ACCESS
STOCKHOLDERS VOTE FOR THE AMENDMENT TO THE WORLD ACCESS DIRECTORS' WARRANT
INCENTIVE PLAN TO CHANGE THE PERFORMANCE CRITERIA OF WORLD ACCESS COMMON STOCK
UNDER THE PLAN.



                                   PROPOSAL 9



                       ELECTION OF WORLD ACCESS DIRECTORS


     The World Access amended certificate of incorporation provides that the
World Access board shall be classified into three classes as nearly equal in
number as possible, such that approximately one-third of the members of the
board shall be elected at each annual meeting of stockholders, and each director
shall serve for a three-year term. The World Access amended certificate of
incorporation further provides that the World Access board shall consist of not
fewer than three members and not more than 12 members, with the exact number of
directors within such range to be fixed from time to time by the World Access
board. If Proposal 5 is approved by the World Access stockholders at the World
Access special meeting, World Access will amend its amended certificate of
incorporation to increase the number of authorized directors from 12 to 15.
Notwithstanding these provisions, the World Access amended certificate of
incorporation provides that whenever the holders of any one or more classes or
series of stock has the right, voting separately by class or series, to elect
directors at an annual or special meeting of stockholders, such directors so
elected shall not be divided into classes, and the number of such directors
shall not be counted in determining the maximum number of directors permitted
under Article IX of the World Access amended certificate of incorporation,
unless expressly provided otherwise by the terms of the class or series in the
World Access amended certificate of incorporation. Messrs. Burmeister, Campbell,
Cipoletti and Sedwick are designees of the Series C preferred stock of World
Access and, as such, are not divided into classes. If Proposal 5 is approved at
the World Access special meeting, all World Access directors, including the
nominees for director named in this joint proxy statement/prospectus, will serve
terms of one year or until their successors are duly elected and qualified.

     The World Access board has fixed the number of directors at 11, and the
World Access board currently is comprised of 11 members. There are three
director positions in the class whose term of office expires in 2000. Two of
these positions are currently held by Stephen J. Clearman and John D. Phillips,
who are standing for reelection. The persons named as proxies are not entitled
to vote for a greater number of persons than the number of nominees named in
this joint proxy statement/prospectus. There are no family relationships among
any World Access directors, executive officers or nominees.

     The World Access board knows of no reason why the nominees may be unable to
serve as a director. If a nominee is unable to serve, the shares represented by
all valid proxies received may be voted for a substitute nominee designated by
the World Access board, or the World Access board may reduce the number of
directors. If any director resigns, dies or is otherwise unable to serve out his
or her term, or the number of directors is increased by the World Access board,
any vacancy so arising may be filled by the World Access board. A director
elected to fill a vacancy shall serve until the next election of the class of
directors to which such director belongs and until his or her successor is
elected and qualified.

eligible to attend during 1999 and (ii) the total number of meetings held by any
committee of the World Access board upon which such director served during 1999.

     The Executive Committee was formed in December 1999 and presently consists
of Messrs. Burmeister, Campbell, Phillips and Tucker. The Executive Committee
performs such duties as are delegated to it by the board of directors, subject
to the limitations on such delegation contained in the Delaware General
Corporation Law.

     The Audit Committee, which presently consists of Messrs. Cipoletti,
Oltramonti and Rigas, recommends engagement of independent auditors for World
Access, reviews and approves services performed by such auditors, reviews and
evaluates World Access' accounting system and its system of internal controls
and performs other related duties delegated to such committee by the World
Access board. The Audit Committee met two times during 1999.

     The Compensation Committee, which presently consists of Messrs. Clearman,
Imlay, Sanders and Sedwick, performs such duties regarding compensation for
executive officers as the World Access board may delegate to such Committee from
time to time. The Compensation Committee met eight times during 1999.

     The World Access board has not established a separate committee of its
members to nominate candidates for election as directors.


WORLD ACCESS DIRECTOR COMPENSATION


     World Access' non-employee directors receive no cash compensation for their
service as directors of World Access. Their compensation is in the form of stock
warrants as discussed below. The directors are reimbursed for out-of-pocket
travel and related expenses incurred in connection with their attendance at
meetings of the World Access' board or its committees and at other World Access
events to which they are invited.

     In December 1994, in an effort to attract and retain experienced executives
to serve as outside directors, the Outside Directors' Warrant Plan was adopted.
World Access' stockholders approved the Warrant Plan at the 1995 Annual Meeting
of Stockholders.

     The purposes of the Warrant Plan are to attract and retain the best
available personnel for service as directors of World Access, to provide
additional incentive to the persons serving as directors, to align director and
stockholder long-term interests and to encourage continued service on the World
Access board. Warrants may be granted under the Warrant Plan only to directors
of World Access who are neither employees of World Access nor of any of its
affiliates. The aggregate number of shares of common stock authorized to be
issued pursuant to the Warrant Plan is 2,400,000, subject to adjustment in
certain instances as described below. The Warrant Plan provides that each
eligible non-employee director elected to serve as a director of World Access on
or after October 1, 1994 may be granted, in the discretion of the World Access
board, warrants to purchase no more than 450,000 shares of common stock in the
aggregate.
                                       218
<PAGE>   232

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 June 1999, the our board granted the following directors warrants to
purchase a total of 201,000 shares of World Access' common stock at an exercise
price of $11.69 per share, the then current market price: Mr. Clearman -- 17,000
shares; Mr. Imlay -- 42,000 shares; Mr. Sanders -- 42,000 shares; and Mr.
Tucker -- 100,000 shares. These warrants, which were fully vested upon issuance,
expire on June 15, 2004.

     In December 1999, Mr. Prelz and Mr. Rigas joined World Access' board and
were each granted warrants to purchase 100,000 shares of World Access' common
stock at an exercise price of $17.62 per share, the then current market price.
These warrants, which were fully vested upon issuance, expire on December 9,
2004.

     In December 1994, we also adopted the Directors' Warrant Incentive Plan
pursuant to which our 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 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 our 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. Upon
stockholder approval at the World Access special meeting, 35% for the four-year
period will be amended to 10% for the two-year period and the number of
authorized shares will be increased to 1.2 million shares.

     In March 1999, pursuant to the Incentive Plan, our board granted each of
Messrs. Clearman, Imlay and Sanders warrants to purchase 50,000 shares of our
common stock at an exercise price of $8.25 per share, 110% of the then current
market price. These warrants became fully vested on December 31, 1999 and expire
on March 10, 2004.

     Notwithstanding the foregoing, the Warrant Plan and the Incentive Plan
provide that warrants awarded pursuant to these plans will become immediately
exercisable (i) if we are consolidated with or acquired by another entity in a
merger, (ii) upon the sale of substantially all of our assets or the sale of at
least 90% of outstanding common stock to a third party, (iii) upon our merger or
consolidation with or into any other corporation or the merger or consolidation
of any corporation with or into us (in which consolidation or merger our
stockholders received distributions of cash or securities as a result thereof),
or (iv) upon our liquidation or dissolution.


                   DESCRIPTION OF WORLD ACCESS' CAPITAL STOCK



WORLD ACCESS COMMON STOCK



     The holders of World Access common stock are entitled to one vote for each
share held of record on all matters to be voted on by the stockholders. There is
no cumulative voting with respect to the election of directors. Accordingly,
holders of a majority of the outstanding shares of World Access common stock and
the holders of the World Access Series A preferred stock, Series D preferred
stock and Series E preferred stock, voting on an as converted to common stock
basis, can elect all members of World Access' board of directors, and holders of
the remaining shares of World Access common stock by themselves cannot elect any
member of the board of directors.



     The holders of World Access common stock are entitled to receive dividends
when, as and if declared by the board of directors out of funds legally
available therefor. In the event of the liquidation, dissolution or winding up
of World Access, the holders of World Access common stock are entitled to share
ratably in all assets remaining available for distribution to them after payment
of liabilities and after provision has been made for each class of stock, if
any, having preference over the World Access common stock.


                                       219
<PAGE>   233


Holders of shares of World Access common stock, as such, have no conversion,
preemptive or other subscription rights. There are no redemption provisions
applicable to the World Access common stock.



WORLD ACCESS PREFERRED STOCK



     Both the World Access and STAR certificates of incorporation authorize
their respective boards of directors to issue shares of preferred stock in one
or more series and to fix the designations, preferences, powers and rights of
the shares to be included in such shares. The STAR certificate of incorporation
authorizes the issuance of 5,000,000 shares of preferred stock. No shares of
STAR preferred stock are issued and outstanding. The World Access certificate of
incorporation authorizes the issuance of 10,000,000 shares of preferred stock,
of which 50,000 shares designated as Series A preferred stock, 350,259.875
shares designated as Series C preferred stock, 184,000 shares designated as
Series D preferred stock, and 9,645 shares designated as Series E are issued and
outstanding. The material terms of the Series A preferred stock, the Series C
preferred stock, the Series D preferred stock and the Series E preferred stock
are summarized below.



  World Access Series A preferred stock



     Dividends.  The holders of the Series A preferred stock are entitled to
receive, when, as and if declared by the World Access board of directors,
quarterly cash dividends at an annual rate on the liquidation preference of the
Series A preferred stock (i.e., $1,000) equal to 4.25%. Dividends payable on the
Series A preferred stock are cumulative and accrue, whether or not declared, on
a daily basis from April 19, 1999.



     Ranking.  The Series A preferred stock ranks, as to dividend and
liquidation rights, senior to World Access common stock, the Series C preferred
stock and the Series D preferred stock.



     Voting rights.  In addition to any voting rights provided by law, the
holders of the Series A preferred stock are entitled to vote on all matters
voted on by holders of World Access common stock voting together as a single
class with the holders of World Access common stock, Series C preferred stock,
Series D preferred stock and other shares entitled to vote thereon. Each holder
of the Series A preferred stock is entitled to cast the number of votes per
share as is equal to the number of votes that such holder would be entitled to
cast had such holder converted its shares into World Access common stock on the
record date for determining the stockholders entitled to vote on any such
matters.



     In addition, unless the consent or approval of a greater number of shares
is then required by law, the vote of the holders of at least 66 2/3% of the
outstanding shares of Series A preferred stock, voting separately as a single
series, is required to: (i) authorize, increase the authorized number of shares
of or issue any shares of any class of stock ranking senior to, or on par with,
the Series A preferred stock; (ii) authorize, adopt or approve an amendment to
the certificate of incorporation of World Access that would increase or decrease
the par value of the Series A preferred stock, or alter or change the powers,
preferences or special rights of the Series A preferred stock, or would alter or
change the powers, preferences or special rights of stock ranking senior to, or
on par with, the Series A preferred stock; (iii) amend or alter the certificate
of incorporation so as to affect the Series A preferred stock adversely and
materially; (iv) authorize or issue any security convertible into, exchangeable
for or evidencing the right to purchase or otherwise receive any shares of any
class or classes of stock ranking senior to, or on par with, the Series A
preferred stock; (v) subject to certain limited exceptions described in the
World Access certificate of incorporation, effect the voluntary liquidation,
dissolution, winding up, recapitalization or reorganization of World Access, or
the consolidation or merger of World Access with or into another entity, or the
sale or other distribution to another entity of all or substantially all of the
assets of World Access; or (vi) authorize, increase the authorized number of
shares of, or issue any shares of capital stock having an optional or mandatory
redemption date earlier than April 21, 2004 or amend the terms of any capital
stock to provide that such capital stock has an optional or mandatory redemption
date earlier than April 21, 2004.


                                       220
<PAGE>   234


     Board of directors representation.  If World Access (i) fails to declare or
pay the full amount of dividends payable on the Series A preferred stock for two
quarterly dividend periods (whether consecutive or not) or (ii) fails to comply
with specific affirmative and negative covenants of World Access set forth in
the Stock Purchase Agreement, dated April 19, 1999, between World Access and The
1818 Fund III, L.P., then the number of directors on the World Access board of
directors must be increased by one, and the holders of the Series A preferred
stock will have the exclusive right to fill such directorship. The person
designated as a director by the holders of the Series A preferred stock will
continue in such position until such breach is cured.



     Redemption.  On or after April 21, 2003, World Access has the right to
redeem the Series A preferred stock for a price per share equal to $1,000 plus
an amount per share equal to all accrued and unpaid dividends through the
redemption date. If a change of control of World Access occurs on or before
April 21, 2001, World Access has the right to redeem the Series A preferred
stock for a price per share equal to $1,250 plus an amount per share equal to
all accrued and unpaid dividends through the redemption date.



     Conversion price.  The Series A preferred stock is convertible, at any time
by the holder thereof, into shares of World Access common stock for a conversion
price equal to $11.50 per share. The conversion price is subject to adjustment
in the event of below market issuances of World Access common stock, stock
dividends, subdivisions, combinations, reclassifications and other distributions
with respect to World Access common stock and certain other instances described
in the World Access certificate of incorporation.



     Mandatory exchange.  If at any time on or after April 19, 2004 until April
19, 2009, the holders of at least 50% of the Series A preferred stock demand
that World Access exchange the Series A preferred stock, then World Access must
exchange all such shares for shares of World Access common stock or subordinated
nonconvertible notes of World Access. The exchange must occur at a per share
price equal to $1,000 per share plus an amount per share equal to all accrued
and unpaid dividends to the exchange date. The exchange date must occur at any
time, or from time to time, during the period from the 40th day following the
date a stockholder demands the exchange to the third anniversary of such date.
Any shares of common stock issued in the exchange will be valued at 95% of the
average market price of World Access common stock for the ten trading days
preceding the applicable exchange date, but in no event greater than the
conversion price then in effect.



     Mandatory conversion.  If for 45 consecutive trading days the market price
of World Access common stock exceeds 261% of the conversion price in effect on
each such trading day, all shares of Series A preferred stock will be
automatically converted into such number of shares of World Access common stock
as equals the number of shares subject to conversion multiplied by the quotient
of $1,000 divided by the conversion price in effect on the last trading day of
such 45-day period.



  World Access Series C preferred stock



     Ranking.  The Series C preferred stock ranks, as to dividends, on par with
the World Access common stock and the Series D preferred stock and junior to the
Series A preferred stock. With respect to liquidation preference, the Series C
preferred stock ranks senior to the World Access common stock, junior to the
Series A preferred stock, and on par with the Series D preferred stock.



     Voting rights.  In addition to any voting rights provided by law, except
with respect to the election of directors, the holders of the Series C preferred
stock are entitled to vote on all matters voted on by holders of World Access
common stock voting together as a single class with the holders of World Access
common stock, Series A preferred stock, Series D preferred stock and other
shares entitled to vote thereon. Each holder of the Series C preferred stock is
entitled to cast the number of votes per share as is equal to the number of
votes that such holder would be entitled to cast had such holder converted its
shares into World Access common stock on the record date for determining the
stockholders entitled to vote on any such matters.


                                       221
<PAGE>   235


     In addition, unless the consent or approval of a greater number of shares
is then required by law, the vote of the holders of at least 66 2/3% of the
outstanding shares of Series C preferred stock, voting separately as a single
series, is required to: (i) authorize, increase the authorized number of shares
of or issue any shares of any class of stock ranking senior to the Series C
preferred stock; (ii) authorize, adopt or approve an amendment to the
certificate of incorporation of World Access that would increase or decrease the
par value of the Series C preferred stock, or alter or change the powers,
preferences or special rights of the Series C preferred stock, or would alter or
change the powers, preferences or special rights of stock ranking senior to the
Series C preferred stock; (iii) amend or alter the certificate of incorporation
so as to affect the Series C preferred stock adversely and materially; (iv)
authorize or issue any security convertible into, exchangeable for or evidencing
the right to purchase or otherwise receive any shares of any class or classes of
stock ranking senior to the Series C preferred stock; and (v) subject to certain
limited exceptions described in the World Access certificate of incorporation,
effect the voluntary liquidation, dissolution, winding up, recapitalization or
reorganization of World Access, or the consolidation or merger of World Access
with or into another entity, or the sale or other distribution to another entity
of all or substantially all of the assets of World Access.



     Board of directors representation.  The holders of the Series C preferred
stock have the right, voting as a separate series, to nominate and elect four
directors to the World Access board of directors (and are not entitled to vote
with respect to the election of any other directors), provided that on the
record date for determining the stockholders eligible to vote for directors, at
least 15% of the originally issued Series C preferred stock is outstanding.
However, if the World Access common stock issuable upon conversion of the Series
C preferred stock equals less than 20% of the outstanding shares of capital
stock of World Access entitled to vote for the election of directors, then, so
long as the outstanding shares of Series C preferred stock equal at least 15% of
the originally issued Series C preferred stock, the holders of the Series C
preferred stock have the right to elect (voting as a separate series), the
number of directors which, as a percentage of the total number of World Access
directors, is at least equal to the percentage of all outstanding shares of
capital stock entitled to vote for the election of directors held by such
holders of Series C preferred stock, on an as converted basis.



     Conversion price.  The Series C preferred stock is convertible, at any time
by the holder thereof, into shares of World Access common stock for a conversion
price equal to $20.38 per share. The conversion price is subject to adjustment
in the event of below market issuances of World Access common stock, stock
dividends, subdivisions, combinations, reclassifications and other distributions
with respect to World Access common stock and other instances described in the
World Access certificate of incorporation.



     Mandatory conversion.  If for 60 consecutive trading days the market price
of World Access common stock exceeds the conversion price in effect on each such
trading day, all shares of Series C preferred stock will be automatically
converted into such number of shares of World Access common stock as equals the
number of shares subject to conversion multiplied by the quotient of $1,000
divided by the conversion price in effect on the last trading day of such 60-day
period.



     In addition, any outstanding shares of Series C preferred stock that have
not been converted into World Access common stock by December 7, 2002 will be
automatically converted into such number of shares of World Access common stock
as is equal to the number of shares of Series C preferred stock subject to
conversion, multiplied by the quotient of (i) $1,000 divided by (ii) the average
market price for the 20 consecutive days ending on December 7, 2002.
Notwithstanding the foregoing, the average market price for the 20 consecutive
days ending on December 7, 2002 may not be less than $11.50 or greater than the
conversion price, and is subject to increase based on a specific decline in the
Nasdaq Composite Index between December 7, 1999 and December 7, 2002.



  World Access Series D preferred stock



     Ranking.  The Series D preferred stock ranks, as to dividends, on par with
the World Access common stock and the Series C preferred stock and junior to the
Series A preferred stock. With respect to


                                       222
<PAGE>   236


liquidation preference, the Series D preferred stock ranks senior to the World
Access common stock, junior to the Series A preferred stock, and on par with the
Series C preferred stock.



     Voting rights.  In addition to any voting rights provided by law, the
holders of the Series D preferred stock are entitled to vote on all matters
voted on by holders of World Access common stock voting together as a single
class with the holders of World Access common stock, Series A preferred stock,
Series C preferred stock and other shares entitled to vote thereon. Each holder
of the Series D preferred stock is entitled to cast the number of votes per
share as is equal to the number of votes that such holder would be entitled to
cast had such holder converted its shares into World Access common stock on the
record date for determining the stockholders entitled to vote on any such
matters.



     Conversion price.  The Series D preferred stock is convertible, at any time
by the holder thereof, into shares of World Access common stock for a conversion
price equal to $18.00 per share. The conversion price is subject to adjustment
in the event of below market issuances of World Access common stock, stock
dividends, subdivisions, combinations, reclassifications and other distributions
with respect to World Access common stock and other instances described in the
World Access certificate of incorporation.



     Mandatory conversion.  If for 60 consecutive trading days the market price
of World Access common stock exceeds the conversion price in effect on each such
trading day, all shares of Series D preferred stock will be automatically
converted into such number of shares of World Access common stock as equals the
number of shares subject to conversion multiplied by the quotient of $1,000
divided by the conversion price in effect on the last trading day of such 60-day
period.



     In addition, any outstanding shares of Series D preferred stock that have
not been converted into World Access common stock by February 14, 2003 will be
automatically converted into such number of shares of World Access common stock
as is equal to the number of shares of Series D preferred stock subject to
conversion, multiplied by the quotient of (i) $1,000 divided by (ii) the average
market price for the 20 consecutive days ending on February 14, 2003.
Notwithstanding the foregoing, the average market price for the 20 consecutive
days ending on February 14, 2003 may not be less than $11.50 or greater than the
conversion price, and subject to increase based on a specific decline in the
Nasdaq Composite Index between February 14, 2000 and February 14, 2003.



  World Access Series E preferred stock



     Ranking.  The Series E preferred stock ranks, as to dividends, on par with
the World Access common stock, the Series C preferred stock, and Series D
preferred stock and junior to the Series A preferred stock. With respect to
liquidation preference, the Series E preferred stock ranks senior to the World
Access common stock, junior to the Series A preferred stock, and on par with the
Series C preferred stock and Series D preferred stock.



     Voting rights.  In addition to any voting rights provided by law, the
holders of the Series E preferred stock are entitled to vote on all matters
voted on by holders of World Access common stock voting together as a single
class with the holders of World Access common stock, Series A preferred stock,
Series C preferred stock, Series D preferred stock and other shares entitled to
vote thereon. Each holder of the Series E preferred stock is entitled to cast
the number of votes per share as is equal to the number of votes that such
holder would be entitled to cast had such holder converted its shares into World
Access common stock on the record date for determining the stockholders entitled
to vote on any such matters.



     Conversion price.  The Series E preferred stock is convertible, at any time
by the holder thereof, into shares of World Access common stock for a conversion
price equal to $21.75 per share. The conversion price is subject to adjustment
in the event of below market issuances of World Access common stock, stock
dividends, subdivisions, combinations, reclassifications and other distributions
with respect to World Access common stock and other instances described in the
World Access certificate of incorporation.



     Mandatory conversion.  If for ten consecutive trading days the market price
of World Access common stock exceeds the conversion price in effect on each such
trading day, all shares of Series E preferred stock will be automatically
converted into such number of shares of World Access common stock

                                       223
<PAGE>   237


as equals the number of shares subject to conversion multiplied by the quotient
of $1,000 divided by the conversion price in effect on the last trading day of
such ten-day period.



     In addition, any outstanding shares of Series E preferred stock that have
not been converted into World Access common stock by July 13, 2003 will be
automatically converted into such number of shares of World Access common stock
as is equal to the number of shares of Series E preferred stock subject to
conversion, multiplied by the quotient of (i) $1,000 divided by (ii) the average
market price for the ten consecutive days ending on July 13, 2003.
Notwithstanding the foregoing, the average market price for the ten consecutive
days ending on July 13, 2003 may not be less than $11.50 or greater than the
conversion price, and subject to increase based on a specific decline in the
Nasdaq Composite Index between July 13, 2000 and July 13, 2003.

(1) The 750,000 and 250,000 options granted to Mr. Phillips at $12.75 per share
    were originally scheduled to vest over a four-year period. In connection
    with Mr. Phillips' execution of a letter agreement with Armstrong
    International Telecommunications, Inc. (see "Executive Employment
    Agreements"), World Access' board elected to vest all these options in full
    upon the consummation of its merger with FaciliCom in December 1999. The
    17,000 options vested immediately upon issuance, and the other 250,000 of
    options will vest one-third on each of the first three anniversaries from
    date of grant.
(2) The first option grant indicated will vest 25% on each of the first four
    anniversaries from date of grant and the second grant will vest one-third on
    each of the first three anniversaries from date of grant.
(3) All options granted will vest 25% on each of the first four anniversaries
    from date of grant.
(4) The 5% and 10% appreciation rates are set forth in the Securities and
    Exchange Commission rules and no representation is made that common stock
    will appreciate at these assumed rates or at all.

     On April 16, 1999, World Access entered into new employment agreements with
each of John D. Phillips, its Chairman and Chief Executive Officer, W. Tod

agreement gives notice of termination. If, during the term of the agreement, Mr.
Phillips' employment with World Access is terminated (i) by World Access without
cause, as defined below, or (ii) by Mr. Phillips for good reason, as defined
below, Mr. Phillips will be entitled to an amount in cash equal to two times his
base annual salary, which will be paid in bi-weekly installments over a period
of 24 months, and to his then current life insurance, disability, medical,
dental and hospitalization benefits for a period of 24 months or such longer
period as may be provided by the terms of the appropriate program, all of Mr.
Phillips' stock options, warrants and stock appreciation rights granted on or
prior to the date of his employment agreement shall become fully vested and
immediately exercisable until the first anniversary of Mr. Phillips' termination
date, and all performance units granted to Mr. Phillips at any time prior to his
termination shall become fully vested.


     Mr. Chmar's employment agreement provides for a base salary of $300,000 per
year. The agreement further provides that Mr. Chmar may be awarded an annual
bonus in the discretion of the World Access board pursuant to a bonus or
incentive plan or otherwise. The initial term of the agreement is three years,
with an automatic one-year extension on each anniversary of the agreement's
effective date unless either party to the agreement gives notice of termination.
If, during the term of the agreement, Mr. Chmar's employment with World Access

                                       230
<PAGE>   244

may be provided by the terms of the appropriate program, all of Mr. Chmar's
stock options, warrants and stock appreciation rights granted on or prior to the
date of his employment agreement shall become fully vested and immediately
exercisable until the first anniversary of Mr. Chmar's termination date, and all
performance units granted to Mr. Chmar at any time prior to his termination
shall become fully vested.

     Mr. Gergel's employment agreement provides for a base salary of $300,000
per year. The agreement further provides that Mr. Gergel may be awarded an
annual bonus in the discretion of our board pursuant to a bonus or incentive
plan or otherwise. The initial term of the agreement is three years, with an
automatic one-year extension on each anniversary of the agreement's effective
date unless either party to the agreement gives notice of termination. If,
during the term of the agreement, Mr. Gergel's employment with World Access is
terminated (i) by World Access without cause or (ii) by Mr. Gergel for good
reason following a change of control, Mr. Gergel will be entitled to an amount
in cash equal to his base annual salary, which will be paid in bi-weekly
installments over a period of 12 months, and to his then current life insurance,
disability, medical, dental and hospitalization benefits for a period of 12
months or such longer period as may be provided by the terms of the appropriate
program, all of Mr. Gergel's stock options, warrants and stock appreciation
rights granted on or prior to the date of his employment agreement shall become
fully vested and immediately exercisable until the first anniversary of Mr.
Gergel's termination date, and all performance units granted to Mr. Gergel at
any time prior to his termination shall become fully vested. Notwithstanding
these provisions, if Mr. Gergel terminates his employment for any reason, in
addition to receiving the same treatment with respect to his options, warrants,
rights and performance units, he shall be entitled to an amount of cash equal to
one-half of his base annual salary and the benefits described above for a period
of six months.


     Mr. Yokley's employment agreement provides for a base salary of $300,000
per year. The agreement further provides that Mr. Yokley will be paid a signing
bonus equal to the costs he incurred to leave his previous job and may be
awarded an annual bonus in the discretion of the World Access board pursuant to
a bonus or incentive plan or otherwise. The initial term of the agreement is
three years, with an automatic one-year extension on each anniversary of the
agreement's effective date unless either party to the agreement gives notice of
termination. This notwithstanding, the term of Mr. Yokley's agreement cannot
expire until 24 months after a change in control of World Access as defined in
the agreement. If, during the term of the agreement, Mr. Yokley's employment
with World Access is terminated (i) by World Access without cause or (ii) by Mr.
Yokley for good reason, Mr. Yokley will be entitled to an amount in cash equal
to two times his base annual salary, which will be paid in bi-weekly
installments over a period of 12 months, and to his then current life insurance,
disability, medical, dental and hospitalization benefits for a period of 12
months or such longer period as may be provided by the terms of the appropriate
program, all of Mr. Yokley's stock options, warrants and stock appreciation
rights granted on or prior to the date of his employment agreement which have
vested or which would vest in the two years following Mr. Yokley's termination
date shall become fully vested and immediately exercisable until the first
anniversary of Mr. Yokley's termination date, and all performance units granted
to Mr. Yokley at any time prior to his termination shall become fully vested.


     For the purposes of the employment agreements with each of Messrs.
Phillips, Chmar and Gergel, the following definitions apply:

     A termination of employment is for cause if the employee has been convicted
of a felony or a felony prosecution has been brought against the employee or if
the termination is evidenced by a resolution adopted in good faith by two-thirds
(2/3) of the board that the employee (i) intentionally and continually failed
substantially to perform his reasonably assigned duties, other than a failure
resulting from the employee's incapacity due to physical or mental illness or
from the employee's assignment of duties that would constitute good reason,
which failure continued for a period of at least 30 days after a written notice
of demand for substantial performance has been delivered to the employee
specifying the manner in which the employee has failed substantially to perform
or (ii) intentionally engaged in illegal conduct or gross misconduct which
results in material economic harm to World Access.

                                       231
<PAGE>   245

     Good reason means a good faith determination by the employee that any one
or more of the following events has occurred, without the employee's express
written consent:


     - the assignment to the employee of any duties inconsistent with the
       employee's position, authority, duties or responsibilities as in effect
       immediately prior to the date of his employment agreement, or any other
       action by World Access that results in a material diminution in such
       position, authority, duties or responsibilities;



     - a reduction by World Access in the employee's base salary, or a change in
       the eligibility requirements or performance criteria under any bonus,
       incentive or compensation plan, program or arrangement under which the
       employee is covered immediately prior to his termination date which
       adversely affects the employee;



     - any failure to pay the employee any compensation or benefits to which he
       is entitled within five days of the date due;



     - World Access' requiring the employee to be based anywhere other than
       within 50 miles of the employee's job location as of the date of his
       employment agreement, except for reasonably required travel on World
       Access' business which is not greater than such travel requirements prior
       to the date of his employment;



     - the taking of any action by World Access that would materially adversely
       affect the physical conditions existing in or under which the employee
       performs his employment duties;



     - the insolvency or the filing of a petition for bankruptcy by World
       Access;



     - any purported termination of the employee's employment for cause by World
       Access which does not comply with his terms of his employment agreement;
       or



     - any breach by World Access of any provision of an employment agreement.


     A change in control shall have occurred if:


     - a majority of the directors of World Access shall be persons other than
       persons:



      - for whose election proxies shall have been solicited by the board; or



      - who are then serving as directors appointed by the board to fill
        vacancies on the board caused by death or resignation, but not by
        removal, or to fill newly-created directorships;



     - a majority of the outstanding voting power of World Access shall have
       been acquired or beneficially owned by any person (other than World
       Access, a subsidiary of World Access or the employee) or any two or more
       persons acting as a partnership, limited partnership, syndicate, or other

     John D. Phillips and Armstrong International Telecommunications, Inc. have

any of its affiliates remains a stockholder of World Access. The provisions of
the letter agreement terminate upon:



     - Mr. Phillips' death or disability;



     - any decision to remove, or to not reelect, Mr. Phillips as the Chief
       Executive Officer of World Access in which at least 50% of the directors
       elected by the holders of World Access Series C preferred stock (or, upon
       conversion into or other acquisition of World Access common stock, by 50%
       of the directors nominated, designated or elected by Armstrong
       International Telecommunications, Epic Interests, Inc. and BFV
       Associates, Inc., or their affiliates) vote in favor of such removal or
       fail to vote in favor of such reelection;



     - the fifth anniversary of the closing of our merger with FaciliCom in the
       event that Mr. Phillips is no longer Chief Executive Officer of World
       Access for any reason; and



     - upon a change of control of World Access.


     On November 29, 1999, we entered into an agreement with A. Lindsay Wallace,
President of our Equipment Group, that provides incentive compensation for Mr.
Wallace in the event of the sale of specified divisions of our Equipment Group.
This agreement provides that World Access will pay to Mr. Wallace:


     - a cash payment equal to 0.75% of the gross consideration received by
       World Access upon the sale of the NACT Switching Division;



     - a cash payment equal to 0.75% of the gross consideration received by
       World Access upon the sale of the Wireless Local Loop Division; and



     - 0.5% of the gross consideration received by World Access upon the sale of
       the Transport and Access Division.


     This agreement also provides that all stock options granted to Mr. Wallace
under our 1991 Stock Option Plan and 1998 Incentive Equity Plan will become
fully vested upon the sale of the NACT Switching Division and the Transport and
Access Division, and those options may be exercised by Mr. Wallace at any time
until the one year anniversary of the termination of Mr. Wallace's employment
with World Access. Additionally, this agreement states that if Mr. Wallace's
employment with World Access is terminated as a direct result of the sale of one
of these divisions, World Access will continue to pay Mr. Wallace's current base
salary through the second anniversary of his termination date. World Access'
obligations under this agreement are conditioned upon Mr. Wallace remaining the
President of the Equipment Group through the closing of the sales of these
divisions, his assistance in facilitating these sales and his agreement to serve
as a full-time employee or consultant with the buyer of these divisions for a
period of six months following the closing date. This agreement may be revoked
at any time by the Chief Executive Officer of World Access, in his sole
discretion.

WORLD ACCESS' COMPENSATION COMMITTEE REPORT


     This report sets forth information on the compensation and benefits
provided to World Access' Chief Executive Officer and other executive officers
of World Access during 1999 and has been prepared by the Compensation Committee
of World Access' board of directors.


     Compensation philosophy.  The Compensation Committee is currently comprised
of four non-employee directors. Among other things, the Compensation Committee
reviews and approves annual executive officer compensation. In general, the
compensation policies adopted by the Compensation Committee are designed to (i)
attract and retain executives capable of leading World Access to meet its
business objectives and (ii) motivate World Access executives to enhance
long-term stockholder value.


     The annual compensation of Mr. Phillips, our Chairman and Chief Executive
Officer, and our other executive officers consists of a combination of base
salary, incentive bonuses and stock options. The Compensation Committee sets
base salaries for executive officers based principally on an assessment of World
Access' short and long-term goals and the specific responsibilities of each
officer. Information on individual performance is provided to the Compensation
Committee by our Chief Executive Officer. In addition to individual performance
against goals and responsibilities, the Compensation Committee is aware of
executive compensation practices at comparable companies (i.e., companies which
are generally of the same size in related industries). The Compensation
Committee uses this information only as a general reference, however, and not to
set specific salary amounts.


     Incentive bonuses.  Annually, the Compensation Committee establishes the
performance goals and range of bonuses under our Short-Term Incentive Plan for
Senior Executives which was approved by our stockholders in June 1999. The
performance goals for 1999 were tied to World Access achieving predefined levels
of:



     - earnings per share;



     - revenue;



     - earnings before interest, taxes, depreciation and amortization; and



     - common stock price appreciation. Each performance goal operates
       independently, so achieving or failing to achieve results from one
       measurement does not reflect the eligible bonus amounts awarded for
       others.



     Stock options.  The stock option program is a long-term incentive plan for
executive officers and other key employees. The objectives of the program are to
align executive and stockholder long-term interests by creating a strong and
direct relationship between executive compensation and stockholder returns. The
Compensation Committee strongly believes that by providing those individuals who
have substantial responsibility for the management and growth of World Access
and the maximizing of stockholder returns with an opportunity to increase their
ownership of common stock, the best interests of stockholders and executives
will be more closely aligned. World Access stock options typically vest over
three to four years, which increases the long-term value of these awards.


     The Compensation Committee's determination of the number of options to
award to an individual executive officer is made in a manner similar to that
described above with respect to the setting of salaries. In addition, in
determining the number of options to be granted to an individual, the
Compensation Committee takes into account the number of options already granted
to that individual and the value of those options.


     Discussion of 1999 Chief Executive Officer compensation.  Based on our
actual performance against Short-Term Incentive Plan goals in 1999, as well as
Mr. Phillips' ability to complete several key strategic initiatives during the
year, the Compensation Committee awarded Mr. Phillips an incentive bonus of $1.0
million. Key strategic initiatives completed by Mr. Phillips included:



     - $50.0 million investment by The 1818 Fund III;



     - acquisition of Comm/Net;

                                       234
<PAGE>   248


     - FaciliCom merger;



     - $75.0 million private placement by institutional investors;



     - pending acquisition of Long Distance International; and



     - pending monetization of the Company's equipment businesses. The
       Compensation Committee also considered Mr. Phillips' continued progress
       in establishing a broad, experienced management team, the efficient
       integration of acquired businesses and the significant increase in the
       Company's market capitalization during 1999.


                                          Submitted by the Compensation
                                          Committee

     Pursuant to Securities and Exchange Commission regulations, this
performance graph is not "soliciting material," is not deemed filed with the
Commission and is not to be incorporated by reference in any of World Access'
filings under the Securities Act or the Securities Exchange Act.


            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE


     Section 16(a) of the Exchange Act requires World Access' directors and
executive officers, and persons who own beneficially more than ten percent of a
registered class of World Access' equity securities, to file with the Securities
and Exchange Commission initial reports of ownership and reports of changes in
ownership of World Access' securities. Directors, executive officers and greater
than ten-percent stockholders are required by Commission regulations to furnish
World Access with copies of all Section 16(a) reports they file.

     To the best of World Access' knowledge, based solely on review of the
copies of such reports furnished to it and representations that no other reports
were required, all Section 16(a) filing requirements applicable to World Access'
directors, executive officers and greater than ten-percent beneficial owners
were complied with during the 1999 fiscal year, except for Mr. Phillips, whose

Statement of Changes in Beneficial Ownership on Form 5 was not filed timely. Mr.
Phillips was required to file a Form 5 to reflect shares of World Access common
stock that he gifted to his children in December 1999.


  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS WITH WORLD ACCESS' DIRECTORS,
                           OFFICERS AND STOCKHOLDERS


     During 1999, World Access paid aggregate fees of approximately $215,900 to
JDP Aircraft II, Inc. for charter flight services provided to World Access. John
D. Phillips, World Access' Chairman and Chief Executive Officer, is the sole
shareholder and an officer of JDP Aircraft II.

     In April 1999, World Access issued 50,000 shares of Series C preferred
stock to The 1818 Fund III for consideration of $50.0 million. Lawrence C.
Tucker, one of World Access' directors, is a co-manager of The 1818 Fund III.

     World Access paid Brown Brothers Harriman & Co. $750,000 for advisory
services in connection with a $75.0 million private placement of World Access
common stock in December 1999 and $830,000 for advisory services in connection
with an $83.1 million private placement of World Access common stock in February
2000. Additionally, World Access paid Brown Brothers Harriman & Co.
approximately $1.6 million for advisory services in connection with the sale of
Telco Systems, Inc. in April 2000. Mr. Tucker is a General Partner of Brown
Brothers Harriman.

     FaciliCom, with which World Access merged in December 1999, has
historically relied on its majority stockholder, Armstrong Holdings, Inc. for
the performance of services, including customer billing. In connection with the
FaciliCom merger, an affiliate of Armstrong Holdings received 309,002 shares of
World Access' Series C preferred stock, which represented approximately 20.0% of
World Access' voting common stock at December 31, 1999. In December 1999, World
Access entered into a two-year services agreement with Armstrong Holdings. The
terms of the agreement includes professional services billed at hourly rates and
data center services based on usage and disk storage space. World Access
believes that the terms of the agreements are competitive with similar services
offered in the industry.

     In December 1999, World Access sold 4,713,128 shares of restricted common
stock for $75.0 million, or $15.91 per share, in a private transaction with a
group of institutional and sophisticated investors. Entities affiliated with
Geocapital Partners, entities affiliated with Gilbert Global Equity Partners,
and Zilkha Capital Partners were the purchasers of $20.0 million, $30.0 million,
and $13.0 million of World Access common stock, respectively, in this
transaction. Stephen J. Clearman, a general partner of Geocapital Partners,
Massimo Prelz Oltramonti, a Managing Director of Gilbert Global Equity Partners,
and John P. Rigas, a Managing Partner of Zilkha Capital Partners, are members of
the World Access board of directors.

     Quorum; vote required.  A majority of the shares of World Access common

following table sets forth the vote required for approval of each of the
proposals to be considered at the World Access special meeting.



<TABLE>
<CAPTION>
---------------------------------------------------------------------------------------
        PROPOSAL                                  VOTE REQUIRED
---------------------------------------------------------------------------------------
<S>                        <C>
  Proposals 1, 3, 7 and 8  - majority in voting power of the shares of World Access
                             voting stock entitled to vote and voting as a single
                             class.
---------------------------------------------------------------------------------------
  Proposal 4               - majority in voting power of the shares of World Access
                             voting stock entitled to vote and voting as a single
                             class; and
                           - majority of the shares of World Access common stock
                             entitled to vote and voting as a single class.
---------------------------------------------------------------------------------------
  Proposals 5 and 6        - 75% in voting power of the shares of World Access voting
                             stock entitled to vote and voting as a single class.
---------------------------------------------------------------------------------------
  Proposal 9               - plurality in voting power of the shares of World Access
                             voting stock entitled to vote for the election of
                             directors and voting as a single class.
---------------------------------------------------------------------------------------
</TABLE>



     The total outstanding shares of World Access common stock for purposes of
calculating the number of shares constituting a quorum and needed for approval
includes the number of shares of World Access common stock issuable upon
conversion of the Series A preferred stock, the Series C preferred stock (except
with respect to the election of directors) and the Series D preferred stock.



     Shares of World Access voting stock that are voted "for," "against" or
"withheld" at the World Access special meeting will be treated as being present
at such meeting for purposes of establishing a quorum and will also be treated
as votes eligible to be cast by the World Access voting stock present in person
or represented by proxy at the World Access special meeting and entitled to vote
on the subject matter. Abstentions will be counted for purposes of determining
both the presence or absence of a quorum for the transaction of business and the
total number of votes cast with respect to a particular matter. Broker non-votes
will be counted for purposes of determining the presence or absence of a quorum
for the transaction of business but will not be counted for purposes of
determining the number of votes cast with respect to the particular proposal on
which the broker has expressly not voted. Because approval of the proposals
described herein other than the election of nominees for director requires the
affirmative vote of a majority in voting power of outstanding shares of World
Access voting stock, abstentions and broker non-votes will have the same effect
as negative votes with respect to these proposals.



     Security ownership by certain beneficial owners and management.  As of the
close of business on the World Access record date, directors and executive
officers of World Access and their respective affiliates may be deemed to be the
beneficial owners of shares of World Access common stock representing
approximately      % of the outstanding voting power of World Access.



     Solicitation and revocability of proxies.  This joint proxy
statement/prospectus is being furnished to holders of World Access voting stock
in connection with the solicitation of proxies by and on behalf of the board of
directors of World Access for use at the World Access special meeting. All
shares of World Access voting stock that are entitled to vote and are
represented at the World Access special meeting, by properly executed proxies
received prior to or at such meeting and not duly and timely revoked, will be
voted at such meeting in accordance with the instructions indicated on such
proxies. If no instructions are indicated, such proxies will be voted for the
approval and adoption of the proposals described herein.



     If any other matters are properly presented for consideration at the World
Access special meeting or any adjournments or postponements thereof, including,
among other things, consideration of a motion to adjourn or postpone such
meeting to another time and/or place, including, without limitation, for the
purpose of soliciting additional proxies, the persons named in the enclosed form
of proxy and voting


                                       240
<PAGE>   254


thereunder will have discretion to vote on such matters in accordance with their
best judgment. Proxies voting against the proposals presented in this joint
proxy statement/prospectus may not be voted for an adjournment or postponement
of the World Access special meeting.



     Any proxy given pursuant to this solicitation may be revoked by the person
giving it any time before it is voted. Proxies may be revoked by:



     - filing with the Secretary of World Access at or before the taking of the
       vote at the World Access special meeting a written notice of revocation
       bearing a later date than the proxy;



     - duly executing a later-dated proxy relating to the same shares and
       delivering it to the Secretary of World Access before the taking of the
       vote at the World Access special meeting; or



     - attending the World Access special meeting and voting in person.
       Attendance at the World Access special meeting will not in and of itself
       constitute a revocation of a proxy.



     Any written notice of revocation or subsequent proxy should be sent so as
to be delivered to World Access, Inc., at 945 E. Paces Ferry Road, Suite 2200,
Atlanta, Georgia 30326, Attention: Secretary, or hand delivered to the Secretary
of World Access at or before the taking of the vote at the World Access special
meeting.



     All expenses of this solicitation, including the cost of preparing and
mailing this joint proxy statement/prospectus to stockholders of World Access,
will be borne by World Access. In addition to solicitation by use of the mails,
proxies may be solicited by directors, officers and employees of World Access in
person or by telephone, telegram or other means of communication. Such
directors, officers and employees will not be additionally compensated, but may
be reimbursed for reasonable out-of-pocket expenses in connection with such
solicitation. Arrangements will also be made with custodians, nominees and
fiduciaries for forwarding of proxy solicitation materials to beneficial owners
of shares held of record by such custodians, nominees and fiduciaries, and World
Access will reimburse such custodians, nominees and fiduciaries for reasonable
expenses incurred in connection therewith.

                            THE STAR SPECIAL MEETING



     Date, time and place of the STAR special meeting.



                                            , 2000


                             11:00 A.M., LOCAL TIME


                             223 EAST DE LA GUERRA


                        SANTA BARBARA, CALIFORNIA 93101



     STAR board of directors' recommendations.  The board of directors of STAR
approved the STAR merger agreement, the PT-1 asset sale agreement and the
transactions considered in both the STAR merger agreement and the PT-1 asset
sale agreement, and recommends that the stockholders of STAR vote:



     - for the approval and adoption of the STAR merger agreement,



     - for the approval and adoption of the PT-1 asset sale agreement, and



     - for the approval of the transactions considered in both the STAR merger
       agreement and the PT-1 asset sale agreement.



     STAR record date.  The board of directors of STAR has fixed             ,
2000 as the date for determination of holders of STAR common stock, who will be
entitled to notice of the STAR special meeting and to vote at the STAR special
meeting.



     Stockholders entitled to vote.  As of the close of business on the STAR
record date,           shares of STAR common stock were outstanding, held by
approximately                holders of record. Each share of outstanding STAR
common stock is entitled to one vote.



     Only STAR stockholders on the close of business on the STAR record date are
entitled to notice of the STAR special meeting and to vote at the STAR special
meeting, or vote on any adjournment or postponement of the STAR special meeting.



     Quorum and vote required.  Each STAR stockholder on the STAR record date is
entitled to cast one vote for each share of STAR common stock held by the STAR
stockholder. The holders of a majority of the shares of STAR common stock issued
and outstanding and entitled to vote at the STAR special meeting, who are
present in person or represented by proxy, will constitute a quorum for the
transaction of business at the STAR special meeting. The approval of the STAR
merger agreement, the PT-1 asset sale agreement and the transactions considered
in both the STAR merger agreement and the PT-1 asset sale agreement require the
affirmative vote of a majority of the outstanding shares of STAR common stock.



     Shares of STAR common stock that are voted "for," "against" or "withheld"
at the STAR special meeting are treated as being present at such meeting for
purposes of establishing a quorum and are also treated as votes eligible to be
cast by the holders of STAR common stock present in person or represented by
proxy at the STAR special meeting and entitled to vote on the subject matter.
Abstentions are counted for purposes of determining both the presence 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 of a quorum for the transaction of business but will
not be counted for purposes of determining the number of votes cast on the
particular proposal that the broker has expressly not voted. Because adoption
and approval of the STAR merger agreement, the PT-1 asset sale agreement, and
the transactions considered in both the STAR merger agreement and the PT-1 asset
sale agreement, require the affirmative vote of a majority of outstanding shares
of STAR common stock, abstentions and broker non-votes will have the same effect
as negative votes.



     Two of STAR's stockholders holding a total of [1%] of the outstanding
common stock of STAR as of the STAR record date have agreed to vote in favor of
the STAR merger.


                                       242

     Security ownership by STAR directors, executive officers and their
affiliates.   As of the close of business on the STAR record date, directors and
executive officers of STAR and their respective affiliates were deemed to be the
owners of shares of STAR common stock representing approximately      % of the
outstanding common stock of STAR.



     Solicitation and revocability of proxies.  This joint proxy
statement/prospectus is being provided to holders of STAR common stock in
connection with the solicitation of proxies by the board of directors of STAR
for use at the STAR special meeting. All shares of STAR common stock entitled to
vote and represented at the STAR special meeting by properly executed proxies
received before or at the meeting and not duly and timely revoked, will be voted
at the meeting pursuant to the instructions on the proxies. If the proxies do
not have instructions, the proxies will be voted for the approval and adoption
of the STAR merger agreement, the PT-1 asset sale agreement and the transactions
considered in both the STAR merger agreement and the PT-1 asset sale agreement.



     If any other matters are properly presented for consideration at the STAR
special meeting or any adjournment or postponement of the STAR special meeting,
including the consideration of a motion to adjourn or postpone the STAR special
meeting to another time and/or place, the persons named in the enclosed form of
proxy will have the right to vote on such matters. However, proxies voting
against the proposals presented in this joint proxy statement/prospectus may not
be voted for an adjournment or postponement of the STAR special meeting.



     Any proxy given pursuant to this solicitation may be revoked by the
stockholder giving it any time before it is voted. Proxies may be revoked by:



     - filing with the Secretary of STAR at or before the taking of the vote at
       the STAR special meeting a later dated written notice revoking the proxy;



     - executing a later-dated proxy for the same shares and delivering it to
       the Secretary of STAR before the vote is taken at the STAR special
       meeting; or



     - attending the STAR special meeting and voting in person. However
       attendance at the STAR special meeting will not in and of itself
       constitute a revocation of a proxy.



     Any written notice of revocation or subsequent proxy should be sent to STAR
Telecommunications, Inc., 223 East De La Guerra Street, Santa Barbara, CA 93101,
Attention: Secretary, or hand delivered to the Secretary of STAR at or before

be solicited by directors, officers and employees of STAR in person or by

the solicitation will not be additionally compensated, but may be reimbursed for
reasonable out-of-pocket expenses for such solicitation. Arrangements will also
be made with custodians, nominees and fiduciaries for forwarding proxy
solicitation materials to beneficial owners of shares held of record by such
custodians, nominees and fiduciaries, and STAR will reimburse such custodians,
nominees and fiduciaries for reasonable expenses for such solicitation.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Shareholders
Communications Telesystems International d.b.a.

WorldxChange Communications



     We have audited the consolidated balance sheets of Communications
Telesystems International d.b.a. WorldxChange Communications as of September 30,
1999 and 1998, and the related consolidated statements of operations,
shareholders' deficit, and cash flows for each of the three years in the period
ended September 30, 1999. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on the
financial statements based on our audits.


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


     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Communications Telesystems International d.b.a. WorldxChange Communications at
September 30, 1999 and 1998, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended September 30,
1999, in conformity with accounting principles generally accepted in the United
States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 (INFORMATION SUBSEQUENT TO SEPTEMBER 30, 1999 AND PERTAINING TO MARCH 31, 2000
       AND FOR THE SIX MONTHS ENDED MARCH 31, 1999 AND 2000 IS UNAUDITED)

1. BUSINESS ACTIVITY


     Communications TeleSystems International d/b/a WorldxChange Communications
("WorldxChange"), a California corporation, is a facilities-based
telecommunications carrier that provides international and domestic
long-distance service to retail and carrier customers. Our retail base is
comprised of residential and commercial customers. Our wholesale base is
comprised of other U.S. and foreign telecommunications carriers and resellers.
We have established retail and carrier operations in the United States, the
Pacific Rim, Canada, Europe and Latin America. WorldxChange also provides
operator, debit/calling card service, toll free, private line and other enhanced
services.



     WorldxChange has established operations in the United Kingdom, France,
Germany, Belgium, The Netherlands, Australia, New Zealand and Canada through
wholly-owned subsidiaries. WorldxChange has additional subsidiaries domiciled in
various other countries; however, the activity of these subsidiaries to date has
not been significant.



     The revenue from WorldxChange's international operations continues to
increase as a percentage of total revenue. For the years ended September 30,
1997, 1998 and 1999 international revenue, including Canada, represented
approximately 13%, 20% and 22% of WorldxChange's total revenue, respectively.


2. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Basis of Presentation


     The accompanying financial statements have been prepared assuming that
WorldxChange will continue as a going concern. WorldxChange has experienced
recurring losses and has a deficiency in working capital and shareholders'
equity. WorldxChange's rapid growth and investments for additional anticipated
growth have required significant capital. Historically, WorldxChange's capital
needs have been met primarily through a combination of a revolving credit
facility, debt, lease financing, cash flows from operations and private
placement equity offerings. During the year ended September 30, 1999,
WorldxChange raised approximately $100 million in private placement offerings
(Note 8). Management believes its available cash, $30 million of financing
received from World Access (Note 13), $15 million of available credit facility
from a shareholder (Note 13), vendor committed financing, along with the
existing credit facility will be adequate to meet WorldxChange's domestic and
international capital requirements for the next twelve months. Management also
believes that WorldxChange's ability to raise additional financing will enable
the continuation of its global expansion. However, without additional financing,
WorldxChange will be required to delay, reduce the scope of and/or eliminate
certain of its future expansion plans, and/or reduce its planned expenditures on
infrastructure and marketing activities.


  Interim Financial Information (Unaudited)

     The accompanying financial statements at March 31, 2000 and for the six
months ended March 31, 1999 and 2000 are unaudited but include all adjustments
(consisting of normal recurring accruals), which, in the opinion of management,
are necessary for a fair statement of the financial position and the operating
results and cash flows for the interim date and periods presented. Results for
the interim period ended March 31, 2000 are not necessarily indicative of
results for the entire year or future periods.

                          WORLDXCHANGE COMMUNICATIONS


           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 (INFORMATION SUBSEQUENT TO SEPTEMBER 30, 1999 AND PERTAINING TO MARCH 31, 2000
       AND FOR THE SIX MONTHS ENDED MARCH 31, 1999 AND 2000 IS UNAUDITED)

  Consolidation


     The accompanying consolidated financial statements include the accounts of
WorldxChange and its wholly and majority owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.


  Cash Equivalents

     Cash equivalents are highly liquid investments purchased with maturities of
three months or less when purchased to be cash equivalents.

  Foreign Currency

     Assets and liabilities of operations outside the United States, for which
the functional currency is not U.S. dollars, are translated into U.S. dollars
using the exchange rate in effect at each period end. Revenues and expenses are
translated at the average exchange rate prevailing during the period. Cumulative
translation adjustments are included as a separate component of shareholders'
deficit. Exchange gains and losses from foreign currency transactions are
included in "Other (income) expense," in the accompanying Consolidated
Statements of Operations.

  Concentration of Credit Risk


     WorldxChange's customer base is comprised of several hundred carrier
customers and over 750,000 residential and commercial users of its direct dial
long distance telephone services, as well as hotels and other users of its
operator-assisted long distance telephone services. These customers are located
principally throughout the United States (U.S.), and to a much lesser extent in
the Pacific Rim, Europe, Latin America, and Canada. WorldxChange's U.S. revenues
from residential and smaller commercial users are billed and collected by local
exchange carriers (LECs). These LECs pass through to WorldxChange their
collection experience with customers billed under these billing agreements.
WorldxChange direct bills carrier and certain commercial customers in the U.S.
and direct bills all customers in its international markets. WorldxChange
performs credit evaluations of the financial condition of these direct bill
customers, and may require a deposit in certain circumstances. Revenue is
reported net of estimated customer credits which are provided for in the
financial statements at the same time the corresponding revenue is recognized.
The Company periodically estimates its reserve requirements for uncollectable
accounts, and the bad debt expense is included in selling, general and
administrative expense. No one customer accounted for more than 10% of revenues
for any period during fiscal 1999, 1998 and 1997 and for the six months ended
March 31, 2000.


  Equipment and Leasehold Improvements


     Equipment and leasehold improvements are recorded at cost and are
depreciated or amortized using the straight-line method over the estimated
useful lives of the assets (generally two to seven years) Equipment under
capital leases are recorded at the net present value of the minimum lease
payments and are amortized over the shorter of the useful life of the asset or
the lease term (ranging from three to seven years). Interests in international
undersea and on-land fiber-optic cable systems are amortized over their
estimated useful lives, typically 20 years.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 (INFORMATION SUBSEQUENT TO SEPTEMBER 30, 1999 AND PERTAINING TO MARCH 31, 2000
       AND FOR THE SIX MONTHS ENDED MARCH 31, 1999 AND 2000 IS UNAUDITED)

  Installation Costs


     Installation costs consists of costs incurred by WorldxChange for the
expansion of its switching capacity and related network. These costs also
include dialer installation costs incurred upon establishing network services
with certain operator services customers. These costs are amortized using the
straight-line method over three years.



  Accrued Network Costs



     Accrued network costs represent an estimate for cost of network services
received from third party telecommunications companies for which WorldxChange
has not been invoiced. The estimates are based upon vendor contract rates and
actual minutes utilized per WorldxChange's records.


  Minority Interest


     Certain of WorldxChange's subsidiaries have sold stock to outside
investors. Income or losses from these operations are allocated to minority
shareholders based on ownership percentages. Losses in excess of the amounts
invested by the minority shareholders are absorbed by WorldxChange. In September
1999, WorldxChange issued 1,554,763 shares of its common stock in exchange for
the shares held by certain minority shareholders of its Australian subsidiary
and a related holding company (Note 8). At September 30, 1999 a 2.2% minority
interest remains in a WorldxChange subsidiary.


  Stock-Based Compensation


     As permitted by SFAS No. 123, Accounting for Stock-Based Compensation,
WorldxChange accounts for compensation expense under its stock-based
compensation plans in accordance with Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees. Pro forma disclosure of net loss,
as if the fair value-based method had been applied in measuring compensation
expense, is presented in Note 8.


  Revenue Recognition


     Revenue is recognized as long distance telecommunications services are
provided. Prepaid calling card revenue is reported net of selling discounts and
recorded when minutes are used. Deferred revenue relates to amounts received
from or billed to customers prior to WorldxChange providing telecommunications
services.



  Cost of Services



     Cost of services is exclusive of depreciation and amortization related to
the services network which is included in "Depreciation and amortization"
presented separately on the consolidated statements of operations.


  Advertising


     WorldxChange charges advertising costs to expense as the costs are
incurred. Total advertising expense was $11,278,000, and $7,717,000 for the six
months ended March 31, 2000 and 1999. Total advertising expense was $17,201,000,
$14,117,000 and $19,118,000 for the years ended September 30, 1997, 1998, and
1999, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 (INFORMATION SUBSEQUENT TO SEPTEMBER 30, 1999 AND PERTAINING TO MARCH 31, 2000
       AND FOR THE SIX MONTHS ENDED MARCH 31, 1999 AND 2000 IS UNAUDITED)

  Use of Estimates

     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.

  Comprehensive Income


     Effective April 1, 1998, WorldxChange adopted SFAS No. 130, Reporting
Comprehensive Income. This statement requires that all components of
comprehensive income be reported, net of any related tax effect, in the
financial statements in the period in which they are recognized. The components
of comprehensive income for WorldxChange include net loss and foreign currency
translation adjustments.


  Segment Information


     Effective October 1, 1998, WorldxChange adopted SFAS No. 131, Disclosures
about Segments of an Enterprise and Related Information. This statement requires
disclosures of certain information about WorldxChange's operating segments,
products, geographic areas in which it operates and its major customers. This
information is presented in Note 12.


  Fair Values of Financial Instruments


     WorldxChange believes that the carrying amounts of its cash, cash
equivalents, accounts receivable, accounts payable, accrued liabilities, and
notes payable approximate their fair market values due to their short-term
nature or variable interest rates.


  New Accounting Standards


     In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activities. In May
1999, the FASB voted to delay the effective date of SFAS No. 133 by one year.
The Company will be required to adopt FAS 133 for fiscal year 2001. This
statement establishes a new model for accounting for derivatives and hedging
activities. Under SFAS No. 133, all derivatives must be recognized as assets and
liabilities and measured at fair value. WorldxChange does not expect the
adoption of SFAS No. 133 to have a material impact on its consolidated financial
position or results of operations.


  Reclassifications

     Certain prior period amounts have been reclassified to conform with the
current period presentation.

3. ACQUISITIONS


     In December 1998, WorldxChange completed a business combination with CTS
Telcom, Inc. and WorldxChange Limited, affiliates under common ownership and
management control, both of which have been accounted for in a manner similar to
a pooling-of-interests. WorldxChange issued 278,000 shares in connection with
the acquisition of WorldxChange Limited, and no consideration was paid for the
acquisition of CTS Telcom. The accompanying pooled consolidated financial
statements are derived from

     In March 1997, WorldxChange entered into its credit facility, which
consists of an accounts receivable-based revolving credit facility and a term
loan. In February 2000, the credit facility was amended to increase the maximum
borrowing capacity, add a bridge loan, extend the maturity date of the revolving
credit agreement and term loan and reduce the interest rate charge. The credit
facility allows WorldxChange to borrow up to a maximum of $65.0 million, subject
to certain restrictions and borrowing base limitations. The maximum available
borrowing base under the revolving credit agreement is $30.0 million and is
determined as a specified percentage of eligible accounts receivable. The
balance outstanding on the revolving credit agreement is reduced by the
application of payments received on collections of accounts receivable. The
accounts receivable revolving credit facility had an outstanding balance of
approximately $16.5 million at March 31, 2000, and $10.5 million available for
borrowing pursuant to the borrowing base limitations. This facility bears
interest at the prime rate plus 1.75% and is repaid through collections of
accounts receivable. The term loan was issued in the amount of $5.0 million,
which at March 31, 2000 had an outstanding balance of approximately $4.7
million, bears interest at the prime rate plus 5.00% and requires monthly
reductions of principal of $300,000 plus interest. The bridge loan has a maximum
borrowing availability of $30.0 million, bears interest at 11% and matures on
February 11, 2001. The maturity date may be extended until October 1, 2003 by
the bridge loan participant. As part of the amended agreement and the
WorldxChange merger agreement, World Access agreed to participate in the bridge
loan and agreed to fund the $30.0 million under the agreement. As of March 31,
2000, the outstanding balance on the bridge loan was $25.0 million and $5.0
million was available for borrowing. In total, as of March 31, 2000,
WorldxChange had $46.2 million borrowed under the credit facility and $15.5
million available for borrowing.



     The revolving credit agreement and the term loan mature at the earlier of
60 days prior to the maturity of the subordinated promissory notes or the notes
due in the ACC Europe acquisition or October 1, 2003. As of March 31, 2000,
WorldxChange was in compliance with the restrictive covenants under the credit
facility. WorldxChange's obligations under the credit facility are secured by
first position in substantially all of its property.


     In May 2000, the credit facility was amended to increase the maximum
borrowing capacity to $80.0 million. The $15.0 million increase in the borrowing
capacity consists of an additional $15.0 million under the bridge loan, under
the same terms and conditions.


     As of September 30, 1998 and 1999, and March 31, 2000, WorldxChange was in
compliance with these covenants, as amended and restructured in order to reflect
the debt and equity financings discussed below and in Note 8 and the acquisition
of two affiliated companies during fiscal 1999 as discussed in

Note 3. WorldxChange's obligations under this agreement are secured by a first
position in substantially all of its assets, excluding equipment where
encumbrances already exist.



     From May through August 1998, WorldxChange issued and sold subordinated
promissory notes in the aggregate principal amounts of $55.0 million. These
notes bear interest at 12.5% per annum, provide for quarterly payments of
interest only and mature on November 30, 2000. These notes provide the lender
the right to require WorldxChange to use a portion of the net proceeds from any
private placement or public offering of WorldxChange's common stock to repay the
notes. As such, the outstanding balance at September 30, 1999 has been reduced
to $45,200,000. As of March 31, 2000 the outstanding balance was $45,200,000.



     In addition, WorldxChange also issued a promissory note in August 1998 in
the amount of $1.2 million representing accrued interest on the subordinated
promissory notes. This note bears interest at the rate of 10.0% per annum,
provides for quarterly payments of interest only and matures on November 30,
2000. In accordance with the terms of the note, this balance was repaid out of
the proceeds of the private placement equity offerings.



     In October 1998, WorldxChange entered into an indefeasible right of use
agreement to lease capacity in a transatlantic telecommunications cable system
for $8,250,000. The purchase was vendor financed with a note that bears interest
at 12.0% per annum and provides for monthly payments of principal and interest.
WorldxChange's obligations under this agreement are secured by a first-priority
security interest in the leased capacity. At March 31, 2000 and September 30,
1999, the outstanding balance related to this agreement was $6,855,030 and
$7,521,000, respectively.



     In February 1999, WorldxChange entered into an indefeasible right of use
agreement to lease capacity in a nationwide fiber optic communications system.
The initial fee for each capacity segment is calculated based on mileage between
cities, as defined per the agreement. This purchase was vendor financed with
notes that bear interest at 12.0% per annum and provide for payments in equal
monthly installments of principal and interest. At March 31, 2000 and September
30, 1999, the outstanding balances related to this agreement were $14,213,922
and $8,693,000 respectively.



     In March 1999, WorldxChange entered into an indefeasible right of use
agreement to lease capacity in a nationwide telecommunications network. Pursuant
to this agreement, WorldxChange signed notes payable to the vendor for the
purchase price. These notes bear interest at 11.5% per annum and provide for
monthly payments of principal and interest. WorldxChange's obligations under
this agreement are secured by a security interest in the leased capacity. At
March 31, 2000 and September 30, 1999, the aggregate outstanding balance were
approximately $15,556,864 and $16,989,000, respectively, which was comprised of
two separate notes with balances outstanding of $12,568,751 and $2,988,113 at
March 31, 2000.



     In June 1999, WorldxChange entered into an indefeasible right of use
agreement to lease capacity in a fiber optic communications system for
$2,969,000. The purchase was vendor financed with a note that bears interest at
10.0% per annum and provides for payments in equal monthly installments of
principal and interest, which are inclusive of all operation and maintenance
fees. At March 31, 2000 and September 30, 1999, the outstanding balances related
to this agreement were $2,351,114 and $2,568,000 respectively.

6. COMMITMENTS AND CONTINGENCIES

  Leases


     WorldxChange leases its primary operating facilities under noncancellable
operating leases which expire at various dates through March 2015. Certain of
these leases contain escalation clauses based on inflation or fixed amounts and
the leases generally require WorldxChange to pay utilities, insurance, taxes and
other operating expenses. Rental expense under such leases was $4,059,000,
$4,783,000, and $3,129,000, respectively, for the six months ended March 31,
2000 and the years ended September 30, 1999 and 1998.



     WorldxChange leases its switches and certain other telecommunication and
computer equipment under capital leases, most of which contain bargain or fair
market value purchase options. At March 31, 2000 and September 30, 1999 and 1998
assets acquired under these leases have an original cost of $51,894,739,
$42,958,000 and $40,099,000, respectively, and accumulated amortization of
$28,713,089, $24,375,000, and $18,515,000, respectively. The amortization of
these assets is included with depreciation and amortization expense presented in
the Consolidated Statements of Operations.

  Commitments for Undersea Cable and Land-based Fiber Optic Cable Systems


     WorldxChange has entered into three agreements to increase its ownership of
undersea cables. These commitments will continue WorldxChange's further
expansion in international markets, and are expected to require incremental
capital expenditures of approximately $18.0 million. Of this balance, $4.0
million will be vendor financed at 11% interest, with monthly principal and
interest payments over a four year amortization period. The remaining $14.0
million will be paid in installments of $6.8 million upon service delivery date
and payments of $3.0 million and $4.2 million on the 1st and 2nd anniversaries
of the service delivery dates, respectively. As of September 30, 1999 and March
31, 2000 these obligations remain outstanding.



     WorldxChange entered into an agreement during the year ended September 30,
1999 to acquire $25.0 million of capacity in land-based fiber optic cable
systems. The vendor has agreed to finance 90% of the commitment at 12% interest,
with monthly principal and interest payments over a five year amortization
period. At September 30, 1999, WorldxChange has purchased for cash of
approximately $10.0 million, leaving $15.0 million to be ordered. As of March
31, 2000, $7.9 million remained to be ordered.


7. INCOME TAXES


     Income taxes are provided for in accordance with the provisions of FASB
Statement No. 109, Accounting for Income Taxes. Under this method, WorldxChange
recognizes deferred tax assets and liabilities for the expected future tax
effects of temporary differences between the carrying amounts and the tax bases
of assets and liabilities, as well as operating loss carryforwards.

     At September 30, 1999, WorldxChange had net operating loss carryforwards
available for federal, state and foreign tax purposes of approximately
$74,200,000, $45,000,000 and $55,000,000 respectively. The federal tax loss
carryforwards will begin expiring in 2007, unless previously utilized. The state
tax loss carryforwards began expiring in 1999 and will continue to expire
through 2003, unless previously utilized. The Canadian and Netherlands net
operating loss carryforwards in the amounts of $6,200,000 and $5,500,000,
respectively, will begin expiring in 2003. Other foreign loss carryforwards may
be carried forward indefinitely. The realization of future domestic benefits
from net operating loss carryforwards may be limited under Section 382 of the

8. SHAREHOLDERS' DEFICIT

  Common Stock


     In September 1998, WorldxChange completed a private placement for the
issuance of 1,659,214 shares of common stock. WorldxChange issued 788,127 shares
of common stock in September 1998 for $10,000,000. The remaining 871,087 shares
of common stock were issued in December 1998 for another $10,000,000. During
fiscal 1999, WorldxChange issued 5,727,000 shares of common stock for proceeds
of $60,000,000.



     In September 1999, WorldxChange issued 1,554,763 shares of its common stock
in exchange for minority interests held in certain of its subsidiaries. The
acquisition was accounted for under the purchase method of accounting at a value
of $17,102,000, or $11.00 per share. The excess value of the stock issued over
the minority interest balance at September 30, 1999 was recorded as goodwill of
$12,194,000. This intangible asset is being amortized on a straight-line basis
over 20 years.

  Preferred Stock


     As of September 30, 1998, WorldxChange had 23 shares of Series A Cumulative
Preferred Stock outstanding. The shares were non-voting and entitled the holders
to certain annual cumulative dividends. During fiscal 1999, all 23 shares were
repurchased by WorldxChange.



     In August 1999, WorldxChange issued 30,000 shares of Series A Convertible
Preferred Stock for $30,000,000. The holders of the Series A Convertible
Preferred Stock are entitled to receive an annual cash dividend of $40 per share
(an aggregate of $100,000 at September 30, 1999). The holders of the Series A
Convertible Preferred Stock are entitled to certain antidilution rights and have
liquidation rights senior to those of common shareholders.



     Each share of Series A Convertible Preferred Stock is convertible into
90.9091 shares of common stock. The stock is convertible at the option of the
holder six months after issuance provided WorldxChange has not completed a
public offering and no such offering is pending. The stock is automatically
convertible: (i) six months from a completed registered public offering,
provided there has been no other registered public offering during the course of
the six months and no registered public offering is pending, or (ii) in the
event there is no registered public offering, two years from the date of
issuance, provided there is no registered public offering pending.


  Stock Options


     WorldxChange's 1996 Stock Option Plan provides for the granting of stock
options to purchase, and the issuance of, up to 3 million shares to employees,
non-exempt directors and consultants. Generally, options are granted at prices
at least equal to fair value of WorldxChange's common stock on the date of grant
as determined by WorldxChange's Board of Directors. In addition, certain
officers and directors have been granted stock options outside the Plan.



     Pro forma information regarding net loss is required by SFAS No. 123, and
has been determined as if WorldxChange had accounted for its employee stock
options under the fair value method of that statement. The fair value of these
options was estimated at the date of grant using the minimum value method and
the following weighted average assumptions for fiscal year 1997, 1998 and 1999,
respectively: risk free interest rate of 6.20%, 5.25% and 5.75%; expected option
life of seven years; and no annual dividends.



     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the vesting period of such options. The
effects of applying SFAS 123 for pro forma disclosure purposes are not likely to
be representative of the effects on pro forma net income or loss in future years
because they do not take into consideration pro forma compensation expenses
related to grants made prior to fiscal 1996. WorldxChange's pro forma
information follows:

9. RELATED PARTY TRANSACTIONS

  Affiliated Long Distance Companies


     In fiscal 1996, WorldxChange began utilizing long distance services from
four affiliated companies owned by a relative of WorldxChange's
officers/shareholders. Billings by the four affiliates for long distance
services provided to WorldxChange were approximately $12,607,000, $5,409,000 and
$1,705,000 for the years ended September 30, 1997, 1998 and 1999, respectively.



     WorldxChange had accounts payable to the four affiliates of $468,000 at
September 30, 1998 and no such amounts outstanding at September 30, 1999.
Effective January 1999, WorldxChange terminated the agreements with these
affiliates.


10. SAVINGS PLAN


     In January 1996, WorldxChange adopted a 401(k) Savings Plan covering
substantially all employees that have been employed for at least one year and
meet other age and eligibility requirements. Participants may elect to
contribute up to six percent of their compensation. WorldxChange matches 25% of
participant contributions. WorldxChange's matching contribution totaled $62,000,
$82,000 and $100,000 during the years ended September 30, 1997, 1998 and 1999,
respectively.


11. LITIGATION AND REGULATION


     WorldxChange is required under federal law and regulations to file tariffs
showing rates, terms and conditions affecting its services. WorldxChange has
filed interstate long distance tariffs with the FCC. The FCC has adopted an
order that, with certain exceptions, rescinds the requirement that carriers such
as WorldxChange maintain FCC tariffs and mandates that tariffs be withdrawn. The
FCC stayed its order pending judicial review. If tariffs are eliminated, it will
probably be necessary for WorldxChange to secure contractual agreements with its
customers providing for many of the terms of its existing tariffs. Absent
tariffs and contracts, WorldxChange believes that disputes could arise
concerning the respective rights of WorldxChange and its customers, which could
hinder WorldxChange's ability to collect its accounts receivable, increase
WorldxChange's overall bad debt losses and collection expenses, and increase
WorldxChange's exposure to unlimited damage claims. The FCC has not proposed to
change its requirements that tariffs for international services be filed, and
WorldxChange continues to file such tariffs.



     The intrastate long distance operations of WorldxChange are also subject to
various state laws. The majority of states require certification or
registrations. WorldxChange has secured the ability to offer intra-state service
in forty-one states. Many states require tariff filing as well.



     WorldxChange has been successful in obtaining all necessary regulatory
approvals to date, although revision of tariffs, authorities and approvals are
being made on a continuing basis and many such requests are pending at any one
time.



     Some states may assess penalties on long distance service providers for
traffic sold prior to tariff approval. Such states may require refunds to be
made to customers. It is the opinion of management that such penalties and
refunds, if any, would not have a material adverse effect on the consolidated
results of operations, financial position or liquidity of WorldxChange.



     In May 1997, the California Public Utilities Commission ("CPUC") issued an
order, which became effective in October 1997, revoking WorldxChange's
Certificate of Public Convenience and Necessity (the

"CPCN") in California and imposing certain other fines and penalties against
WorldxChange based on the CPUC's findings that WorldxChange violated California
laws and regulations requiring WorldxChange to obtain prior consumer
authorization before switching consumers' long distance carriers. As a result of
the revocation for WorldxChange's CPCN, WorldxChange cannot provide intrastate
telecommunication services in California. In addition, WorldxChange must, among
other things, (i) pay a $19.6 million fine to the state of California, $2
million of which has been paid with the balance suspended so long as
WorldxChange is not found to have committed any future violations of California
law or CPUC directives; (ii) reimburse the CPUC for $100,000 in prosecution
costs which has also been paid; and (iii) pay approximately $1.9 million in
reparations to consumers, of which $1,211,000 remains payable at September 30,
1999 and $899,000 remains payable at March 31, 2000.



     Under the CPUC's order, the suspension of WorldxChange's CPCN and the other
sanctions and fines imposed on WorldxChange are binding on any successor of
WorldxChange. WorldxChange may apply to the CPUC for reinstatement of the CPCN
after October 22, 2000, although there can be no assurance that such
reinstatement would be granted.



     In addition, WorldxChange is subject to certain legal, regulatory and
administrative proceedings, claims and inquiries arising in the ordinary course
of business, some of which involve claims for substantial amounts of damages.
The ultimate outcome of such proceedings, claims or inquiries cannot be
predicted at this time. It is management's opinion, after consultation with its
legal counsel, that any such liability or possible restrictions placed on
WorldxChange's operations resulting from the ultimate resolution of such
proceedings, claims, and inquiries, beyond that provided, would not have a
material effect on WorldxChange's consolidated financial position or
WorldxChange's future consolidated results of operations or cash flows.


12. SEGMENT INFORMATION


     In 1999, WorldxChange adopted SFAS 131.  The prior year's segment
information has been restated to present three reportable operating segments.
WorldxChange's segments are organized on the basis of geographic location and
include North America, Pacific Rim and Europe. None of WorldxChange's operating
segments have been aggregated.



     WorldxChange evaluates performance and allocates resources based on profit
or loss from operations before interest expense, other income (loss) and
minority interest. The accounting policies of the reportable segments are the
same as those described in the basis of presentation and summary of significant
accounting policies. Intersegment sales and transfers between geographic regions
are accounted for at prices that approximate arm's length transactions. No
single customer accounted for 10% or more of revenues in fiscal 1999, 1998 or
1997.



     WorldxChange's regional segments earn revenue from direct-dial long
distance services as well as operator, debit/calling card, toll free, private
line and other enhanced services to residential customers, other
telecommunications carriers, and small to medium-sized businesses. Each of
WorldxChange's reportable regions represents a strategic business segment that
functions in an environment with common economic characteristics determined
based on historical and expected future performance.

13. SUBSEQUENT EVENTS


     On November 4, 1999, WorldxChange acquired the outstanding shares of
certain European subsidiaries of ACC Corp, a subsidiary of AT&T. The operations
of these subsidiaries are located in the United Kingdom, Germany, France and
Italy. As part of this transaction, WorldxChange also acquired from ACC Corp a
switch located in the United States and certain indefeasible rights of use of a
transatlantic telecommunications cable system. The $113 million purchase price
for this transaction was comprised of $60 million cash and a $53 million, 12%
per annum interest rate note due on or before December 28, 2000. The acquisition
has been accounted for as a purchase, and accordingly, the excess purchase price
over the fair value of the net assets acquired of approximately $85.0 million
has been preliminarily allocated to goodwill and customer base based on
management's estimates. Goodwill will be amortized on a straight-line basis over
twenty years and the customer base will be amortized over five years.



     WorldxChange financed $50 million of the cash payment through the issuance
in November 1999 of 50,000 shares of Series B Convertible Preferred Stock to two
existing shareholders for $50 million. The Series B Convertible Preferred Stock
has a liquidation preference of $1,000 per share.


     Unless previously converted prior to 180 days after the issuance date, on
the 180th day each share of Series B Stock shall be convertible automatically,
without any additional consideration by the holder thereof, into 111.111 fully
paid and non-assessable common shares.


     Assuming that the acquisition of ACC Corp. had occurred on the first day of
WorldxChange's fiscal year ended September 30, 1998, pro forma condensed
consolidated results of operations would have been as follows (in thousands):

up to $15 million from a shareholder. The loans bear interest at 15% and becomes

     In February 2000, WorldxChange signed an Agreement and Plan of merger with
World Access, Inc. Concurrent with the signing of the Agreement and Plan of
merger, World Access, Inc. agreed to participate in WorldxChange's existing loan
and security agreement with a financial institution whereby the existing line
increased by $30 million. The $30 million consists of a term loan, which bears
interest at 11% and is payable in total on February 11, 2001. In May 2000, the
loan and security agreement was amended to increase the term loan to $45
million.



     In January 2000, WorldxChange negotiated payment terms with a network
provider to finance outstanding invoices payable to the carrier. Under the terms
of the agreement, the Company agreed to pay to the carrier a total of $24.1
million for services through August 31, 1999. Payments in the aggregate of $4.3
million are due and payable in monthly installments through September 30, 2000
and the remainder is payable in monthly installments of $1.25 million beginning
October 2000. The financing bears interest at 13%.



14. RECENT EVENT (UNAUDITED)



     Effective August 1, 2000, WorldxChange has entered into an Executive
Management Services Agreement with World Access under which World Access will
manage the operations and business affairs of WorldxChange as if World Access
and WorldxChange had already completed the merger. The agreement will terminate
on the first to occur of the following:



     - the parties terminate the WorldxChange merger agreement,



     - the completion of the WorldxChange merger,



     - World Access gives WorldxChange 15 days notice or WorldxChange materially
       breaches the services agreement or



     - World Access materially breaches the services agreement.

INDEPENDENT AUDITORS' REPORT



     We have audited the accompanying consolidated balance sheets of TelDaFax AG
as of December 31, 1999, 1998 and 1997, and the related consolidated statements
of operations, retained earnings, 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, the financial statements referred to above present fairly,
in all material respects, the financial position of TelDaFax AG as of December
1999, 1998 and 1997, and the results of its operations and its cash flows for
the years then ended in conformity with generally accepted accounting
principles.



     As discussed in Note 11, the Company's 1999 financial statements have been
restated to account for the acquisition of Demuth & Dietl only from the
acquisition date, October 4, 1999.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS


                               (DM IN THOUSANDS)



1. DESCRIPTION OF BUSINESS



     TelDaFax Telefon-, Daten- und Fax Transfer GmbH & Co.  KG was founded in
March 1995. On July 1, 1997, TelDaFax Telefon-, Daten und Fax Transfer GmbH &
Co. KG transferred all of its business assets to TelDaFax GmbH. TelDaFax AG was
then established through a change in the legal form of TelDaFax GmbH. The
transfer of the business assets was a contribution-in-kind to TelDaFax GmbH in
exchange for new shares. The assets were contributed at their fair market value.
The step-up amounts were treated as contributed capital. Following a resolution,
of the General Meeting of Shareholders on May 27, 1998, the legal form was
changed again to that of a stock corporation in accordance with Sections 190ff
and 238ff of the law governing changes in legal form. The incorporation into
TelDaFax AG was entered in the Commercial Register on June 10, 1998.



     TelDaFax AG ("TelDaFax"), a German company, provides voice telephony, fax
and data transmission services along with mobile hardware and mobile phone cards
throughout Germany. TelDaFax provides fixed-to-mobile, -international and
-domestic connections to commercial and residential customers through a
communication network of dedicated lines leased from Deutsche Telekom AG. Prior
to January 1, 1998, these services were provided solely to commercial customers.
The receipt of a Category 4 License from the Federal Ministry for Post and
Telecommunications for fixed-line telecommunication services on September 30,
1997 and the full liberalization of the German telecommuncations market on
January 1, 1998 allowed TelDaFax to expand these services to residential
customers under the carrier number "01030". TelDaFax also provides internet
access through its majority-owned subsidiary GeoNet Systems GmbH and mobile
phone hardware and calling cards through its majority-owned subsidiaries Demuth
& Dietl + Co. Kommunikationselektronic GmbH and Netztel Plus Drillish AG.
TelDaFax also wholly owns BNC Kommunikationssysteme GmbH & Co. KG, an operating
division responsible for monitoring TelDaFax router system, and TelDaFax
Vertriebs GmbH, an operating division consisting of TelDaFax's sales
organization.



     The accompanying financial statements have been prepared in accordance with
United States generally accepted accounting principles ("US GAAP"). TelDaFax
maintains its financial records in accordance with German statutory regulations
which represents generally accepted accounting principles in Germany. Generally,
accepted accounting principles in Germany vary in certain respects from US GAAP.
Accordingly, TelDaFax has recorded certain adjustments in order that these
financial statements be in accordance with US GAAP.



2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES



  Interim Financial Information (Unaudited)



     The unaudited consolidated balance sheet as of March 31, 2000 and the
related consolidated statements of operations, shareholders' equity and cash
flows for each of the three month periods ended March 31, 2000 and 1999, have
been prepared pursuant to the rules and regulations of the Securities and
Exchange Commission. All adjustments, in the opinion of management, that are
necessary for the fair statement of the financial position and the operating
results and cash flows for the interim periods have been presented. Results of
operations for the three month periods ended March 31, 2000 and 1999 are not
necessarily indicative of the results that may be achieved for the entire years
or future periods.



  Principles of Consolidation



     The accompanying consolidated financial statements include the accounts of
TelDaFax and its wholly-and majority-owned financial subsidiaries. All
significant intercompany accounts and transactions have been eliminated in
consolidation.

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)



  Cash and Cash Equivalents



     TelDaFax considers all highly liquid investments purchased with an initial
maturity of three months or less to be cash equivalents.



  Concentration of Credit Risk



     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash and cash equivalents
and trade receivables. Concentration of credit risk with respect to trade
receivables is limited as the outstanding total represents a large number of
customers with individually small balances. The Company does not require
collateral or other security interests against trade receivable balances;
however, it does maintain reserves for potential credit losses and such losses
have been within management's expectations. Substantially all of the Company's
cash and cash equivalents are deposited in financial institutions in Germany.



  Inventories



     Inventories are stated at the lower of cost or market and are valued using
the weighted-average method.



  Property, Plant and Equipment



     Property, plant and equipment, including equipment under capital leases, is
valued at acquisition or production cost and depreciated or amortized over their
estimated useful lives, or over the lives of the underlying leases, if less,
using the straight-line method as follows:

  Intangible Assets



     Intangible assets mainly relate to goodwill, acquired software, acquired
technical know-how and the license for fixed-line telecommunication services.



     Goodwill is amortized on a straight-line basis over 15 years. Goodwill as
of March 31, 2000 and December 31, 1999, 1998 and 1997, net of accumulated
amortization, was DM 21,238, DM 8,049, DM 3,852 and DM 2,694, respectively.



     Software is capitalized when it is purchased from a third party, either in
the ordinary course of business or, in the case of the acquisition of
subsidiaries, as allocated goodwill. It is amortized over 4 years.



     Technical know-how is capitalized as allocated goodwill in the case of the
acquisition of subsidiaries. It is amortized over 4 years.



     Technical know-how as of March 31, 2000 and December 31, 1999, 1998 and
1997, net of accumulated amortization, was DM 1,042, DM 1,245, DM 2,054 and DM
2,614, respectively.



     TelDaFax evaluates the recoverability of long-lived assets by measuring the
carrying amount of the assets against the estimated undiscounted future cash
flows associated with them. At the time such evaluations indicate that the
future undiscounted cash flows of long-lived assets are not sufficient to
recover the carrying value of such assets, the assets are adjusted to their fair
values. Based on these evaluations, there were no material adjustments to the
carrying value of long-lived assets during the three month period ended March
31, 2000 and 1999 and the years ended December 31, 1999, 1998 and 1997.

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)



  Revenue Recognition



     Telecommunication revenue is recognized as services are provided. Mobile
hardware revenue is reported when the customer takes possession of the product
and prepaid mobile calling card revenue is recorded when the minutes are used.



  Advertising



     TelDaFax expenses advertising costs as incurred. Total advertising costs
were DM 4,862, DM 5,041, DM 24,696, DM 12,321 and DM 3,434 for the three month
periods ended March 31, 2000 and 1999 and the years ended December 31, 1999,
1998 and 1997, respectively.



  Recent Accounting Pronouncements



     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 133 "Accounting for Derivative
Instruments and Hedging Activities", which establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. In June 1999, SFAS No.
133 was amended by SFAS 137, "Accounting for Derivative Instruments and Hedging
Activities -- Deferral of the Effective Date of SFAS 133". As a result of this
amendment, SFAS No. 133 shall be effective for all fiscal quarters of all fiscal
years beginning after June 15, 2000. In accordance with SFAS No. 133, an entity
is required to recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value.
SFAS No. 133 requires that changes in the derivatives' fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. Special
accounting for qualifying hedges allows a derivative's gains and losses to
offset related results on the hedged item in the income statement and requires
that a company formally document, designate and assess the effectiveness of
transactions that receive hedge accounting. The Company does not expect the
adoption of this standard to have a material effect on its consolidated
financial position or results of operations.



  Use of Estimates



     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 could differ from those estimates.



  Reclassification



     Certain amounts in prior years financial statements have been reclassified
to conform with the presentation in 1999.

<PAGE>   302

                          AGREEMENT AND PLAN OF MERGER

     THIS AGREEMENT AND PLAN OF MERGER, dated as of February 11, 2000 (this
"Agreement"), is made and entered into among WORLD ACCESS, INC., a Delaware
corporation ("WAXS"), STI Merger Co., a Delaware corporation and wholly-owned
subsidiary of WAXS ("Merger Sub"), and STAR TELECOMMUNICATIONS, INC., a Delaware
corporation ("STAR").

                              W I T N E S S E T H:

     WHEREAS, the Boards of Directors of STAR and WAXS deem it advisable and in
the best interests of each corporation and its respective stockholders that STAR
and WAXS engage in a business combination in order to advance the long-term
strategic business interests of STAR and WAXS;

     WHEREAS, the combination of STAR and WAXS shall be effected by the terms of
this Agreement through a merger as outlined below (the "Merger");

     WHEREAS, in furtherance thereof, the respective Boards of Directors of
STAR, Merger Sub and WAXS have approved the Merger, upon the terms and subject
to the conditions set forth in this Agreement, pursuant to which each share of
common stock, par value $0.001 per share, of STAR ("STAR Common Stock") issued
and outstanding immediately prior to the Effective Time (as defined in Section
1.3) will be converted into the right to receive the consideration set forth in
Section 1.6;

     WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code"), and the regulations
promulgated thereunder; and

     WHEREAS, simultaneously with the execution and delivery of this Agreement,
WAXS and Christopher E. Edgecomb and Samer Tawfik (the "Principal Stockholders")
are entering into an agreement (the "Voting and Stock Transfer Restriction
Agreement") pursuant to which each Principal Stockholder will agree to, among
other things, vote in favor of the Merger and certain restrictions on the
transfer of the consideration received in the Merger.

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement, and intending to be legally bound hereby, the parties hereto agree as
follows:

                                   ARTICLE I

                                   THE MERGER

     1.1 The Merger.  Upon the terms and subject to the conditions set forth in
this Agreement, and in accordance with the General Corporation Law of the State
of Delaware (the "DGCL"), STAR shall be merged with and into Merger Sub at the
Effective Time (as defined below). Following the Merger, the separate corporate
existence of STAR shall cease and Merger Sub shall continue as the surviving
corporation (the "Surviving Corporation").

     1.2 Closing.  Subject to the satisfaction or waiver of the conditions set
forth in Article VI, the closing of the Merger and the transactions contemplated
by this Agreement (the "Closing") will take place on the second business day
following the satisfaction or waiver of such conditions, unless another time or
date is agreed to in writing by the parties hereto (the date of the Closing
being referred to herein as the "Closing Date"). The Closing shall be held at
the offices of Long Aldridge & Norman LLP, 303 Peachtree Street, Suite 5300,
Atlanta, Georgia 30303, unless another place is agreed to by the parties hereto.

     1.3 Effective Time.  On the Closing Date the parties shall (i) file a
certificate of merger (the "Certificate of Merger") in such form as is required
by, and executed in accordance with, the relevant provisions of the DGCL and
(ii) make all other filings or recordings required under the DGCL in
                                       A-1
<PAGE>   303

connection with the Merger. The Merger shall become effective at such time as
the Certificate of Merger is duly filed with the Delaware Secretary of State or
at such subsequent time as WAXS and STAR shall agree and as shall be specified
in the Certificate of Merger (the date and time the Merger becomes effective
being the "Effective Time").

     1.4 Effects of the Merger.  At and after the Effective Time, the Merger
will have the effects set forth in the DGCL. Without limiting the generality of
the foregoing, and subject thereto, at the Effective Time all the property,
rights, privileges, powers, licenses, authorizations and franchises of Merger
Sub and STAR shall be vested in the Surviving Corporation, and all debts,
liabilities and duties of Merger Sub and STAR shall become the debts,
liabilities and duties of the Surviving Corporation.

     1.5 Certificate of Incorporation/Bylaws.  The certificate of incorporation
and bylaws of Merger Sub, as in effect immediately prior to the Effective Time,
shall be the certificate of incorporation and bylaws of the Surviving
Corporation, until thereafter changed or amended as provided therein or by
applicable law.

     1.6 Conversion of Securities.  At the Effective Time, by virtue of the
Merger and without any action on the part of WAXS, Merger Sub, STAR or the
holders of any of the following securities:

          (a) [Intentionally omitted.]

          (b) Each share of STAR Common Stock issued and outstanding and
     directly or indirectly owned or held by STAR or a Subsidiary thereof at the
     Effective Time shall, by virtue of the Merger, cease to be outstanding and
     shall be canceled and retired and no capital stock of WAXS or other
     consideration shall be delivered in exchange therefor.

          (c) Subject to Section 2.4, each share of STAR Common Stock issued and
     outstanding immediately prior to the Effective Time (other than the
     Dissenter's Shares (as defined in Section 8.12)) shall be converted into
     the right to receive, at the election of WAXS by written notice to STAR
     prior to the Closing, (i) the number of shares of WAXS Common Stock
     obtained by solving for "X" in the following formula (the "Exchange
     Ratio"):

           X = 7.81 + Z
               --------
                    20

or (ii) such number of shares of WAXS Common Stock as shall equal sixty percent
(60%) of the Exchange Ratio and an amount in cash equal to forty percent (40%)
of the sum of $7.81 plus "Z" (as defined below); provided, however, that WAXS
and STAR expressly agree that, notwithstanding anything in this Agreement to the
contrary, in order to ensure that the Merger satisfies the continuity of
interest requirement under Treasury Regulation Section 1.368-1(e), that in no
event shall WAXS issue cash for more than forty-five percent (45%) of the
outstanding shares of STAR Common Stock, including for purposes of this
calculation cash paid for fractional shares pursuant to Section 2.4 and cash
paid for Dissenters' Shares.

For purposes of this Section 1.6, "Z" shall equal the PT-1 Excess Proceeds (as
defined in Section 8.12) divided by 62,856,702. All shares of STAR Common Stock,
at the Effective Time, shall no longer be outstanding and shall automatically be
canceled and retired and each holder of a certificate representing any such
shares (a "Certificate") shall cease to have any rights with respect thereto,
except as set forth in this Section 1.6(c), Section 2.4 or at law. The shares of
WAXS Common Stock issued pursuant to this Section 1.6(c) together with any cash
in lieu of fractional shares paid pursuant to Section 2.4 shall be referred to
herein as the "Merger Consideration."

     1.7 STAR Stock Options.

          (a) At the Effective Time, by virtue of the Merger and without any
     further action on the part of STAR, WAXS, Merger Sub or the holder of any
     outstanding option, warrant or other right to acquire STAR capital stock (a
     "STAR Stock Option"), each STAR Stock Option will be automatically
     converted into a WAXS Stock Option (as defined in Section 3.1(b)) to
     purchase shares of WAXS Common Stock in an amount equal to the number of
     shares of STAR Common Stock covered under
                                       A-2
<PAGE>   304

     such STAR Stock Option multiplied by the Exchange Ratio (rounded to the
     nearest whole number of shares of WAXS Common Stock) at a price per share
     of WAXS Common Stock equal to the per share option exercise price specified
     in the STAR Stock Option divided by the Exchange Ratio (rounded to the
     nearest whole cent). Each such WAXS Stock Option shall contain terms and
     provisions which are substantially similar to those terms, conditions and
     provisions governing the original STAR Stock Option, except that references
     to STAR in such STAR Stock Option will be deemed to refer to WAXS and the
     date of grant of the STAR Stock Option shall be deemed to be the date of
     grant of such WAXS Stock Option. At the Effective Time, for purposes of
     interpretation of such new WAXS Stock Option, (i) all references in any
     stock option plan of STAR shall be deemed to refer to WAXS; (ii) any stock
     option plan of STAR which governs the STAR Stock Option shall continue to
     govern the WAXS Stock Option substituted therefor; and (iii) WAXS shall, as
     soon as practicable after the Effective Time, issue to each holder of an
     outstanding STAR Stock Option a document evidencing the foregoing issued
     and substituted WAXS Stock Option by WAXS. It is the intention of the
     parties: (1) that, subject to applicable law, STAR Stock Options assumed by
     WAXS qualify, following the Effective Time, as incentive stock options, as
     defined in Section 422 of the Code, to the extent that STAR Stock Options
     qualified as incentive stock options prior to the Effective Time, (2) that
     each holder of a STAR Stock Option shall receive a new WAXS Stock Option
     which preserves (but does not increase) the excess of the fair market value
     of the shares subject to such STAR Stock Option immediately before the
     Effective Time over the aggregate option price of such shares immediately
     before the Effective Time, if any such excess then exists, (3) that the
     terms, conditions, restrictions and provisions of the WAXS Stock Option be
     substantially similar to the terms, conditions, restrictions and provisions
     of the STAR Stock Option, and (4) any terms conditions, restrictions or
     provisions of a STAR Stock Option applicable to a number of shares rather
     than a percentage or fraction of shares should be appropriately adjusted
     based upon the Exchange Ratio. Without the prior written consent of WAXS
     (which may be withheld in its discretion), no new options shall be issued
     by STAR on or after the date hereof, including, without limitation, under
     any stock option plan currently maintained by STAR.

          (b) With respect to each STAR Stock Option converted into a WAXS Stock
     Option pursuant to Section 1.7(a), and with respect to the shares of WAXS
     Common Stock underlying such option, WAXS shall file and keep current all
     requisite registration statements, on Form S-8 or other appropriate form,
     for as long as such options remain outstanding, which registration
     statement shall include a prospectus meeting the requirements of General
     Instruction C to Form S-8 with respect to affiliates of STAR, subject at
     all times to compliance with all applicable federal and state securities
     laws.

          (c) After the date of this Agreement, STAR agrees that it will not
     grant any restricted stock, stock appreciation rights or limited stock
     appreciation rights and also agrees that it will not permit cash payments
     to holders of STAR Stock Options in lieu of the substitution therefor of
     WAXS Stock Options, as described in this Section 1.7.

     1.8 Certain Adjustments.  If between the date hereof and the Effective
Time, the outstanding WAXS Common Stock or STAR Common Stock shall have been
changed into a different number of shares or different class by reason of any
reclassification, recapitalization, stock split, split-up, combination, exchange
of shares or similar capital stock event or a stock dividend or dividend payable
in any other securities shall be declared with a record date within such period,
or any similar event shall have occurred, the Exchange Ratio shall be
appropriately adjusted to provide to the holders of STAR Common Stock and the
holders of STAR Stock Options the same economic effect as contemplated by this
Agreement prior to such event.

                            EXCHANGE OF CERTIFICATES

     2.1 Exchange Fund.  At least five (5) days prior to the mailing of the
Joint Proxy Statement/Prospectus (as defined in Section 5.1), WAXS shall
appoint a commercial bank or trust company reasonably acceptable to STAR to act
as exchange agent hereunder (the "Exchange Agent") for the purpose of exchanging
Certificates for the Merger Consideration. Immediately prior to the Effective
Time, WAXS shall deposit with the Exchange Agent, in trust for the benefit of
holders of shares of STAR Common Stock, cash payable and certificates
representing the WAXS Common Stock issuable pursuant to Section 1.6 in exchange
for outstanding shares of STAR Common Stock. WAXS agrees to deposit with the
Exchange Agent from time to time as needed, cash sufficient to pay cash in lieu
of fractional shares pursuant to Section 2.4 and any dividends and other
distributions pursuant to Section 2.3. Any cash and certificates of WAXS Common
Stock deposited with the Exchange Agent shall hereinafter be referred to as the
"Exchange Fund".

     2.2 Exchange Procedures.  As soon as reasonably practicable after the
Effective Time, WAXS shall cause the Exchange Agent to mail to each holder of a
Certificate (other than to holders of Dissenter's Shares) (i) a letter of
transmittal which shall advise such holder of the effectiveness of the Merger
and specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent, and which letter shall be in customary form and have such other
provisions as WAXS may reasonably specify and (ii) instructions for effecting
the surrender of such Certificates in exchange for the applicable Merger
Consideration. Upon surrender of a Certificate to the Exchange Agent together
with such letter of transmittal, duly executed and completed in accordance with
the instructions thereto, and such other documents as may reasonably be required
by the Exchange Agent, the holder of such Certificate shall be entitled to
receive in exchange therefor promptly (A) one or more shares of WAXS Common
Stock (which shall be in uncertificated book entry form unless a physical
certificate is requested) representing, in the aggregate, the whole number of
shares that such holder has the right to receive pursuant to Section 1.6 (after
taking into account all shares of STAR Common Stock then held by such holder),
and (B) a check in the amount equal to the cash that such holder has the right
to receive pursuant to the provisions of Section 1.6(c), if any, and this
Article II, including cash in lieu of any additional shares of WAXS Common Stock
pursuant to Section 2.4 and dividends and other distributions pursuant to
Section 2.3. No interest will be paid or will accrue on any cash payable
pursuant to 1.6(c), Section 2.3 or Section 2.4. In the event of transfer of
ownership of STAR Common Stock which is not registered in the transfer records
of STAR, one or more shares of WAXS Common Stock evidencing, in the aggregate,
the proper number of shares of WAXS Common Stock, a check in the proper amount
of cash in lieu of any additional shares of WAXS Common Stock pursuant to
Section 2.4, a check in the proper amount of cash pursuant to Section 1.6(c) and
any dividends or other distributions to which such holder is entitled pursuant
to Section 2.3, may be issued with respect to such STAR Common Stock to such a
transferee if the Certificate representing such shares of STAR Common Stock is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and to evidence that any applicable stock
transfer taxes have been paid.

     2.3 Distributions with Respect to Unexchanged Certificates.  No dividends
or other distributions declared or made with respect to shares of WAXS Common
Stock with a record date after the Effective Time shall be paid to the holder of
any unexchanged Certificate with respect to the shares of WAXS Common Stock that
such holder would be entitled to receive upon surrender of such Certificate and
no cash payment in lieu of fractional shares of WAXS Common Stock shall be paid
to any such holder pursuant to Section 2.4 until such holder shall surrender
such Certificate in accordance with Section 2.2. Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
paid to such holder of shares of WAXS Common Stock issuable in exchange
therefor, without interest, (a) promptly after the time of such surrender, the
amount of any cash payable in lieu of fractional shares of WAXS Common Stock to
which such holder is entitled pursuant to Section 2.4 and the amount of
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of WAXS Common Stock, and (b)
at the appropriate payment date, the amount of
                                       A-4
<PAGE>   306

dividends or other distributions with a record date after the Effective Time but
prior to such surrender and a payment date subsequent to such surrender payable
with respect to such shares of WAXS Common Stock.

     2.4 No Fractional Shares of WAXS Common Stock.

          (a) No certificates or scrip or shares of WAXS Common Stock
     representing fractional shares of WAXS Common Stock or book-entry credit of
     the same shall be issued upon the surrender for exchange of Certificates
     and such fractional share interests will not entitle the owner thereof to
     vote or to have any rights of a stockholder of or a holder of shares of
     WAXS Common Stock.

          (b) Notwithstanding any other provision of this Agreement, each holder
     of shares of STAR Common Stock exchanged pursuant to the Merger who would
     otherwise have been entitled to receive a fraction of a share of WAXS
     Common Stock (after taking into account all Certificates delivered by such
     holder) shall receive, in lieu thereof, cash (without interest) in an
     amount equal to the product of (i) such fractional part of a share of WAXS
     Common Stock multiplied by (ii) the average of the daily closing price for
     a share of WAXS Common Stock on the Nasdaq for the ten (10) consecutive
     trading days in which such shares are traded on the Nasdaq, ending at the
     close of trading on the date of the Effective Time or, if such date is not
     a business day, the business day immediately preceding the date on which
     the Effective Time occurs. As promptly as practicable after the
     determination of the amount of cash, if any, to be paid to holders of
     fractional interests, the Exchange Agent shall so notify WAXS, and WAXS
     shall promptly deposit such amount with the Exchange Agent and shall cause
     the Exchange Agent to promptly forward payments to such holders of
     fractional interests subject to and in accordance with the terms hereof.

     2.5 No Further Ownership Rights in STAR Common Stock.  As applicable, all
shares of WAXS Common Stock issued and cash paid upon conversion of shares of
STAR Common Stock in accordance with the terms of Article I and this Article II
(including any cash paid pursuant to Section 2.4) shall be deemed to have been
issued or paid in full satisfaction of all rights pertaining to the shares of
STAR Common Stock.

     2.6 Termination of Exchange Fund.  Any portion of the Exchange Fund which
remains undistributed to the holders of Certificates for six (6) months after
the Effective Time shall be delivered to the Surviving Corporation or otherwise
on the instruction of the Surviving Corporation, and any holders of the
Certificates who have not theretofore complied with this Article II shall
thereafter look only to the Surviving Corporation and WAXS for the Merger
Consideration with respect to the shares of STAR Common Stock formerly
represented thereby to which such holders are entitled pursuant to Section 1.6
and Section 2.2, any cash in lieu of fractional shares of WAXS Common Stock to
which such holders are entitled pursuant to Section 2.4 and any dividends or
distributions with respect to shares of WAXS Common Stock to which such holders
are entitled pursuant to Section 2.3. Any such portion of the Exchange Fund
remaining unclaimed by holders of shares of STAR Common Stock five (5) years
after the Effective Time (or such earlier date immediately prior to such time as
such amounts would otherwise escheat to or become property of any Governmental
Entity (as defined in Section 3.1(c)(3)) shall, to the extent permitted by law,
become the property of the Surviving Corporation free and clear of any claims or
interest of any Person previously entitled thereto.

     2.7 No Liability.  None of WAXS, Merger Sub, STAR, the Surviving
Corporation or the Exchange Agent shall be liable to any Person in respect of
any Merger Consideration from the Exchange Fund delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

     2.8 Investment of the Exchange Fund.  The Exchange Agent shall invest any
cash included in the Exchange Fund as directed by the Surviving Corporation on a
daily basis. Any interest and other income resulting from such investments shall
promptly be paid to the Surviving Corporation.

     2.9 Lost Certificates.  If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the Person claiming
such Certificate to be lost, stolen or destroyed and, if required by the
Surviving Corporation, the posting by such Person of a bond in such reasonable
amount as
                                       A-5
<PAGE>   307

the Surviving Corporation may direct as indemnity against any claim that may be
made against it with respect to such Certificate, the Exchange Agent will
deliver in exchange for such lost stolen or destroyed Certificate the applicable
Merger Consideration with respect to the shares of STAR Common Stock formerly
represented thereby, any cash in lieu of fractional shares of WAXS Common Stock,
and unpaid dividends and distributions on shares of WAXS Common Stock
deliverable in respect thereof, pursuant to this Agreement.

     2.10 Withholding Rights.  Each of the Surviving Corporation and WAXS shall
be entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any holder of shares of STAR Common Stock such
amounts as it is required to deduct and withhold with respect to the making of
such payment under the Code and the rules and regulations promulgated
thereunder, or any provision of state, local or foreign tax law. To the extent
that amounts are so withheld by the Surviving Corporation or WAXS, as the case
may be, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the shares of STAR Common Stock
in respect of which such deduction and withholding was made by the Surviving
Corporation or WAXS, as the case may be.

     2.11 Stock Transfer Books.  The stock transfer books of STAR shall be
closed immediately upon the Effective Time and there shall be no further
registration of transfers of shares of STAR Common Stock thereafter on the
records of STAR. On or after the Effective Time, any Certificates presented to
the Exchange Agent or WAXS for any reason shall be converted as provided in
Articles I and II hereof.

                                  ARTICLE III


                         REPRESENTATIONS AND WARRANTIES


     3.1 Representations and Warranties of WAXS and Merger Sub.  Except as set
forth in the WAXS SEC Reports (as defined below) filed and publicly available
prior to the date hereof or the WAXS Disclosure Schedule delivered by WAXS to
STAR prior to the execution of this Agreement (the "WAXS Disclosure Schedule")
(each section of which qualifies the correspondingly numbered representation and
warranty or covenant to the extent specified therein), WAXS and Merger Sub
represent and warrant to STAR as follows:

          (a) Organization; Standing and Power; Subsidiaries.

             (1) Each of WAXS, its Subsidiaries (as defined in Section 8.12) and
        Merger Sub is a corporation duly organized, validly existing and in good
        standing under the laws of its jurisdiction of incorporation or
        organization, has the requisite power and authority to own, lease and
        operate its properties and to carry on its business as now being
        conducted, except where the failure to be so organized, existing and in
        good standing or to have such power and authority would not have a
        Material Adverse Effect on WAXS, and is duly qualified and in good
        standing to do business in each jurisdiction in which the nature of its
        business or the ownership or leasing of its properties makes such
        qualification necessary other than in such jurisdictions where the
        failure to so qualify or to be in good standing would not have a
        Material Adverse Effect on WAXS. The copies of the certificate of
        incorporation and bylaws of WAXS and Merger Sub which were previously
        furnished or made available to STAR are true, complete and correct
        copies of such documents as in effect on the date of this Agreement.

             (2) Exhibit 21.1 to WAXS's Annual Report on Form 10-K for the year
        ended December 31, 1998 includes all the Subsidiaries of WAXS which as
        of the date of this Agreement are Significant Subsidiaries (as defined
        in Rule 1-02 of Regulation S-X of the SEC). All the outstanding shares
        of capital stock of, or other equity interests in, each such Significant
        Subsidiary have been validly issued and are fully paid and nonassessable
        and are owned directly or indirectly by WAXS, free and clear of all
        pledges, claims, liens, charges, encumbrances and security interests of
        any kind or nature whatsoever (collectively "Liens") and free of any
        other restriction (including any restriction on the right to vote, sell
        or otherwise dispose of such capital stock or other ownership
        interests). Neither WAXS nor any of its Subsidiaries directly or
                                       A-6
<PAGE>   308

        indirectly owns any equity or similar interest in, or any interest
        convertible into or exchangeable or exercisable for any equity or
        similar interest in, any corporation, partnership, joint venture or
        other business association or entity (other than the Subsidiaries of
        WAXS) that is or would reasonably be expected to be material to WAXS and
        its Subsidiaries taken as a whole.

          (b) Capital Structure.  As of February 7, 2000:

             (1) The authorized capital stock of WAXS consists of (A)
        150,000,000 shares of WAXS Common Stock, of which 53,787,805 shares are
        outstanding and no shares are held in the treasury of WAXS and (B)
        10,000,000 shares of Preferred Stock, par value $.01 per share, of which
        50,000 shares designated as 4.25% Cumulative Senior Perpetual
        Convertible Preferred Stock, Series A, par value $.01 per share (the
        "Series A Preferred Stock"), and 350,259.875 shares designated as
        Convertible Preferred Stock, Series C (the "Series C Preferred Stock"),
        are outstanding. WAXS has reserved or has available 4,347,827 shares of
        WAXS Common Stock for issuance upon conversion of the Series A Preferred
        Stock and 18,027,478 shares of WAXS Common Stock for issuance upon
        conversion of the Series C Preferred Stock. All issued and outstanding
        shares of the capital stock of WAXS are duly authorized, validly issued,
        fully paid and nonassessable, and no class of capital stock is entitled
        to preemptive rights. In addition to the rights described in Section
        3.1(b) of the WAXS Disclosure Schedule, there are outstanding options,
        warrants or other rights (a "WAXS Stock Option") to acquire 13,133,837
        shares of capital stock from WAXS.

             (2) No bonds, debentures, notes or other indebtedness of WAXS
        having the right to vote on any matters on which holders of capital
        stock of WAXS may vote ("WAXS Voting Debt") are issued or outstanding.

             (3) Except as otherwise set forth in this Section 3.1(b) and as
        contemplated by Section 1.5 and Section 1.6, there are no securities,
        options, warrants, calls, rights, commitments, agreements, arrangements
        or undertakings of any kind to which WAXS or any of its Subsidiaries is
        a party or by which any of them is bound obligating WAXS or any of its
        Subsidiaries to issue, deliver or sell, or cause to be issued, delivered
        or sold, additional shares of capital stock or other voting securities
        of WAXS or any of its Subsidiaries or obligating WAXS or any of its
        Subsidiaries to issue, grant, extend or enter into any such security,
        option, warrant, call right, commitment, agreement, arrangement or
        undertaking. There are no outstanding obligations of WAXS or any of its
        Subsidiaries to repurchase, redeem or otherwise acquire any shares of
        capital stock of WAXS or any of its Subsidiaries.

          (c) Authority; No Conflicts.

             (1) WAXS and Merger Sub have all requisite corporate power and
        authority to enter into this Agreement and to consummate the Merger and
        the other transactions contemplated hereby, subject, in the case of
        WAXS, to the approval by the stockholders of WAXS by the Required WAXS
        Vote (as defined in Section 3.1(g)) of this Agreement, the Merger and
        the other transactions contemplated hereby and, in the case of Merger
        Sub, the affirmative vote of WAXS, as sole stockholder thereof, of this
        Agreement, the Merger and the other transactions contemplated hereby.
        The execution and delivery of this Agreement and the consummation of the
        Merger and the other transactions contemplated hereby have been duly
        authorized by all necessary corporate action on the part of WAXS and
        Merger Sub, subject, in the case of WAXS, to the approval by the
        stockholders of WAXS of this Agreement, the Merger and the transactions
        contemplated hereby by the Required WAXS Vote and subject, in the case
        of Merger Sub, to the affirmative vote of WAXS, as sole stockholder
        thereof, of this Agreement, the Merger and the other transactions
        contemplated hereby. This Agreement has been duly executed and delivered
        by WAXS and Merger Sub and constitutes a valid and binding agreement of
        each of WAXS and Merger Sub, enforceable against it in accordance with
        its terms, except to the extent that its enforceability may be limited
        by applicable bankruptcy, insolvency, reorganization, moratorium or
        other laws affecting the enforcement of creditors' rights
                                       A-7
<PAGE>   309

        generally or by general equitable principles (regardless of whether such
        enforceability is considered in a proceeding in equity or at law).

             (2) Subject, in the case of WAXS, to the approval by the
        stockholders of WAXS of this Agreement, the Merger and the transactions
        contemplated hereby by the Required WAXS Vote and, in the case of Merger
        Sub, the affirmative vote of WAXS, as sole stockholder thereof, of this
        Agreement, the Merger and the other transactions contemplated hereby,
        the execution and delivery of this Agreement by WAXS and Merger Sub does
        not, and the consummation by WAXS and Merger Sub of the Merger and the
        other actions contemplated hereby will not, conflict with, or result in
        any violation of, or constitute a default (with or without notice or
        lapse of time, or both) under, or give rise to a right of termination,
        amendment, cancellation or acceleration of any obligation or the loss of
        a material benefit under, or the creation of a Lien on any assets (any
        such conflict, violation, default, right of termination, amendment,
        cancellation or acceleration, loss or creation, a "Violation") of: (A)
        any provision of the certificate of incorporation or bylaws of WAXS, any
        Subsidiary of WAXS or Merger Sub, or (B) except as would not have a
        Material Adverse Effect on WAXS and subject to obtaining or making the
        consents, approvals, orders, authorizations, registrations, declarations
        and filings referred to in paragraph (3) below, any loan or credit

        judgment, order, decree, statute, law, ordinance, rule or regulation
        applicable to WAXS, any Subsidiary of WAXS or their respective
        properties or assets.

             (3) No consent, approval, order or authorization of, or
        registration, declaration or filing with, any supranational, national,
        state, municipal, local or foreign government, any instrumentality,
        subdivision, court, administrative agency or commission or other
        authority thereof, or any quasi-governmental or private body exercising
        any supranational, national, state, municipal, local or foreign
        regulatory, taxing, importing or other governmental or
        quasi-governmental authority (a "Governmental Entity"), is required by
        or with respect to WAXS, any Subsidiary of WAXS or Merger Sub in
        connection with the execution and delivery of this Agreement by WAXS or
        Merger Sub or the consummation of the Merger and the other transactions
        contemplated hereby, except for those required under or in relation to
        (A) the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
        (the "HSR Act"), (B) state securities or "blue sky" laws (the "Blue Sky

        limitation, those of the United States Federal Communication Commission
        (the "FCC"), (J) any filings and approvals expressly contemplated by
        this Agreement, and (K) such consents, approvals, orders,
        authorizations, registrations, declarations and filings the failure of

        WAXS. Consents, approvals, orders, authorizations, registrations,
        declarations and filings required under or in relation to any of the
        foregoing clauses (A) through (K) are hereinafter referred to as
        "Necessary Consents".

          (d) Reports and Financial Statements.

             (1) WAXS has filed all required registration statements,
        prospectuses, reports, schedules, forms, statements and other documents
        required to be filed by it under the federal securities laws with the
        SEC since January 1, 1998 (collectively, including all exhibits thereto,
        the "WAXS SEC Reports"). No Subsidiary of WAXS, including, without
        limitation Merger Sub, is required to file any form, report,
        registration statement, prospectus or other document with the SEC not
        otherwise filed with a WAXS SEC Report. As of the respective times such
        documents were filed or, as applicable, became effective, or as
        subsequently amended, the WAXS SEC Reports
                                       A-8
<PAGE>   310

        complied as to form and content, in all material respects, with the
        requirements of the Securities Act and the Exchange Act, as the case may
        be, and the rules and regulations promulgated thereunder and, taken as a
        whole, the WAXS SEC Reports do 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. Each of the
        financial statements (including the related notes) included in the WAXS
        SEC Reports (or, if amended or superseded by a filing prior to the date
        of this Agreement, then on the date of such filing) presents fairly, in
        all material respects, the consolidated financial position and
        consolidated results of operations and cash flows of WAXS and its
        Subsidiaries as of the respective dates or for the respective periods
        set forth therein all in conformity with GAAP consistently applied
        during the periods involved except as otherwise noted therein, and
        subject, in the case of the unaudited interim financial statements, to
        normal and recurring year-end adjustments that have not been and are not
        expected to be material in amount. All of such WAXS SEC Reports, as of
        their respective dates (or as of the date of any amendment to the
        respective WAXS SEC Report filed prior to the date of this Agreement),
        complied or will comply as to form in all material respects with the
        applicable requirements of the Securities Act and the Exchange Act and
        the rules and regulations promulgated thereunder.

             (2) Since December 31, 1998, WAXS and its Subsidiaries have not
        incurred any liabilities that are of a nature that would be required to
        be disclosed on a balance sheet of WAXS and its Subsidiaries or the
        footnotes thereto prepared in conformity with GAAP, other than (A)
        liabilities incurred in the ordinary course of business or (B)
        liabilities that would not have a Material Adverse Effect on WAXS.

          (e) Information Supplied.  None of the information supplied or to be

     Proxy Statement/Prospectus (as defined herein) will, on the date it is
     first mailed to WAXS's and STAR's stockholders, as applicable, or at the
     time of the WAXS Stockholders Meeting or the STAR Stockholders Meeting, as
     applicable, contain any untrue statement of a material fact or omit to
     state any 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. The Joint Proxy Statement/Prospectus will,
     on the date it is first mailed to WAXS's and STAR's stockholders and at the
     time of the WAXS Stockholders Meeting and the STAR Stockholders Meeting,
     comply as to form in all material respects with the requirements of the
     Exchange Act and the rules and regulations promulgated thereunder.

     of the holders of any class or series of WAXS capital stock necessary to
     adopt this Agreement and approve the Merger and the other transactions
     contemplated hereby.

          (h) Required Merger Sub Board Approval.  The Board of Directors of
     Merger Sub, by resolutions duly adopted by a unanimous written consent and

     any class or series of Merger Sub capital stock necessary to adopt this
     Agreement and approve the Merger and the other transactions contemplated
     hereby.

          (j) Litigation: Compliance with Laws.

             (1) There is no suit, investigation, action or proceeding pending
        or, to the Knowledge of WAXS, threatened, against or affecting WAXS or
        any Subsidiary of WAXS having, or which would have a Material Adverse
        Effect on WAXS, nor is there any judgment, decree, injunction, rule or
        order of any Governmental Entity or arbitrator outstanding against WAXS
        or any Subsidiary of WAXS having, or which would have a Material Adverse
        Effect on WAXS.

             (2) Except as would not have a Material Adverse Effect on WAXS,
        WAXS and its Subsidiaries hold all permits, licenses, variances,
        authorizations, exemptions, orders and approvals of all Governmental
        Entities including, without limitation, the FCC and state public
        utilities commissions, which are necessary for the operation of the
        businesses of WAXS and its Subsidiaries (the "WAXS Permits"). Such WAXS
        permits are valid and in full force and effect and WAXS and its
        Subsidiaries are in compliance with the terms of the WAXS Permits,
        except where the failure to be valid and in full force and effect or to
        so comply would not have a Material Adverse Effect on WAXS. The
        businesses of WAXS and its Subsidiaries are not being conducted in
        violation of, and WAXS has not received any notices of violations with
        respect to, any law, ordinance or regulation of any Governmental Entity,
        except for possible violations which would not have a Material Adverse
        Effect on WAXS. WAXS is not aware of any threatened suspension,
        cancellation or invalidation of any such WAXS Permit. Except as set
        forth in the WAXS SEC Reports or except as would not have a Material
        Adverse Effect on WAXS, neither WAXS nor any of its Subsidiaries has
        received notice from either the FCC or any state public utilities
        commissions of any complaint filed therewith concerning WAXS or any of
        its Subsidiaries, operations or services.

          (k) Absence of Certain Changes or Events.  Except for liabilities
     incurred in connection with this Agreement or the transactions contemplated
     hereby, and except as permitted by Section 4.1, since December 31, 1998
     through and including the date hereof, (i) WAXS and its Subsidiaries have
     conducted, in all material respects, their business only in the ordinary
     course and (ii) there has not been any change, circumstance or event which
     has had, or would reasonably be expected to have, a Material Adverse Effect
     on WAXS, other than any change, circumstance or effect relating (A) to the
     economy or financial markets in general, or (B) in general to the
     industries in which WAXS and its Subsidiaries operate and not specifically
     relating to WAXS and its Subsidiaries.

          (l) Intellectual Property.  Except as would not have a Material
     Adverse Effect on WAXS: (i) WAXS and each of its Subsidiaries owns, or is
     licensed to use (in each case, free and clear of any Liens, or claim of
     rights therein by any third party) all Intellectual Property (as defined
     below) used in or necessary for the conduct of its business as currently
     conducted, (ii) the use of any Intellectual Property by WAXS and its
     Subsidiaries does not infringe on or otherwise violate the rights of any
     Person and is in accordance with any applicable license pursuant to which
     WAXS or any Subsidiary acquired the right to use any Intellectual Property;
     (iii) to the Knowledge of WAXS, no Person is challenging, infringing on or
     otherwise violating any right of WAXS or any of its Subsidiaries with

     its
                                      A-10
<PAGE>   312

     Subsidiaries; and (iv) neither WAXS nor any of its Subsidiaries has
     received any written notice of any pending claim with respect to any
     Intellectual Property used by WAXS and its Subsidiaries and to WAXS's
     Knowledge no Intellectual Property owned and/or licensed by WAXS or its
     Subsidiaries is being used or enforced in a manner that would result in the
     abandonment, cancellation or unenforceability of such Intellectual
     Property. For purposes of this Agreement, "Intellectual Property" shall
     mean trademarks, service marks, brand names, certification marks, trade
     dress and other indications of origin, the goodwill associated with the
     foregoing and registrations in any jurisdiction of, and applications in any

          (m) Brokers or Finders.  No agent, broker, investment banker,
     financial advisor or other firm or Person is or will be entitled to any
     broker's or finder's fee or any other similar commission or fee in
     connection with any of the transactions contemplated by this Agreement
     based upon arrangements made by or on behalf of WAXS, except Donaldson,
     Lufkin & Jenrette Securities Corporation (the "WAXS Financial Advisor"),
     whose fees and expenses will be paid by WAXS in accordance with WAXS's
     agreement with such firm, a copy of which has been, or will be promptly
     when available, provided to STAR.

          (n) Opinion of WAXS Financial Advisor.  WAXS has received the opinion
     of the WAXS Financial Advisor, dated the date of this Agreement, to the
     effect that as of such date, the Merger Consideration is fair, from a
     financial point of view, to WAXS and its stockholders, a copy of which has

        period prior to the date of this Agreement; (iv) there are no material
        liens on any of the assets of WAXS or any of its Subsidiaries with
        respect to Taxes, other than liens for Taxes not yet due and payable or

             (2) There are no contracts, agreements, plans or arrangements,
        including but not limited to the provisions of this Agreement, covering

          (p) Certain Contracts.  Neither WAXS nor any of its Subsidiaries is a
     party to or bound by (i) any "material contract" (as such term is defined
     in Item 601(b)(10) of Regulation S-K of the SEC), (ii) any noncompetition
     agreement or any other agreement or arrangement that limits or otherwise
     restricts WAXS or any of its Subsidiaries or any successor thereto, from
     engaging or competing in any line of business or in any geographic area,
     which agreement or arrangement would have a Material Adverse Effect on WAXS
     or the Surviving Corporation after giving effect to the Merger, or (iii)
     any agreement or arrangement between WAXS or any of its Subsidiaries, on
     the one hand, and any affiliates, directors or officers of WAXS or its
     Subsidiaries, on the other hand, that is not on arm's-length terms. All

     respective terms, except to the extent that such enforceability may be
     subject to applicable bankruptcy, insolvency, moratorium, reorganization,
     or other laws affecting the enforcement or creditors' rights generally or
     by general equitable principles, and other than such contracts which by
     their terms are no longer in force or effect. Neither WAXS nor its
     Subsidiaries are in violation or breach of or default under any such
     contract, nor to WAXS's and its Subsidiaries' Knowledge, is any other party
     to any such contract in violation or breach or other default under any such
     contract, except for any such violation, breach or default which would not
     have a Material Adverse Effect on WAXS.

     3.2 Representations and Warranties of STAR.  Except as set forth in the
STAR SEC Reports (as defined below) filed and publicly available prior to the
date hereof or the STAR Disclosure Schedule delivered by STAR to WAXS prior to
the execution of this Agreement (the "STAR Disclosure Schedule") (each section
of which qualifies the correspondingly numbered representation and warranty or
covenant to the extent specified therein), STAR represents and warrants to WAXS
as follows:

          (a) Organization; Standing and Power; Subsidiaries.

             (1) Each of STAR and its Subsidiaries is a corporation duly
        organized, validly existing and in good standing under the laws of its
        jurisdiction of incorporation or organization, has the requisite power
        and authority to own, lease and operate its properties and to carry on
        its business as now being conducted, except where the failure to be so
        organized, existing and in good standing or to have such power and
        authority would not have a Material Adverse Effect on STAR, and is duly
        qualified and in good standing to do business in each jurisdiction in
        which the nature of its business or the ownership or leasing of its
        properties makes such qualification necessary, other than in such
        jurisdictions where the failure to so qualify or to be in good standing
        would not have a Material Adverse Effect on STAR. The copies of the
        certificate of incorporation and bylaws of STAR which were previously
        furnished or made available to WAXS are true, complete and correct
        copies of such documents as in effect on the date of this Agreement.

             (2) Exhibit 21.1 to STAR's Annual Report on Form 10-K for the year
        ended December 31, 1998 includes all the Subsidiaries of STAR which as
        of the date of this Agreement are Significant Subsidiaries (as defined
        in Rule 1-02 of Regulation S-X of the SEC). All the outstanding shares
        of capital stock of, or other equity interests in, each such Significant
        Subsidiary have been validly issued and are fully paid and nonassessable
        and are owned directly or indirectly by STAR, free and clear of all
        Liens and free of any other restriction (including any restriction on
        the right to vote, sell or otherwise dispose of such capital stock or
        other ownership interests). Neither STAR nor any of its Subsidiaries
        directly or indirectly owns any equity or similar interest in, or any
        interest convertible into or exchangeable or exercisable for any equity
        or similar interest in, any corporation, partnership, joint venture or
        other business association or entity (other than the Subsidiaries of
        STAR), that is or would reasonably be expected to be material to STAR
        and its Subsidiaries taken as a whole.

        and no class of capital stock is entitled to preemptive rights. There
        are outstanding options, warrants or other rights to acquire 4,173,571
        shares of capital stock from STAR. Section 3.2(b) of the STAR Disclosure

        having the right to vote on any matters on which holders of capital
        stock of STAR may vote ("STAR Voting Debt") are issued or outstanding.

             (3) Except as otherwise set forth in this Section 3.2(b), there are
        no securities, options, warrants, calls, rights, commitments,
        agreements, arrangements or undertakings of any kind to which STAR or
        any of its Subsidiaries is a party or by which any of them is bound
        obligating STAR or any of its Subsidiaries to issue, deliver or sell, or
        cause to be issued, delivered or sold, additional shares of capital
        stock or other voting securities of STAR or any of its Subsidiaries or
        obligating STAR or any of its Subsidiaries to issue, grant, extend or
        enter into any such security, option, warrant, call, right, commitment,
        agreement, arrangement or undertaking. There are no outstanding
        obligations of STAR or any of its Subsidiaries to repurchase, redeem or
        otherwise acquire any shares of capital stock of STAR or any of its
        Subsidiaries.

          (c) Authority; No Conflicts.

             (1) STAR has all requisite corporate power and authority to enter
        into this Agreement and to consummate the Merger and the other
        transactions contemplated hereby, subject to the approval by the
        stockholders of STAR by the Required STAR Vote (as defined in Section
        3.2(g)) of this Agreement, the Merger and the other transactions
        contemplated hereby. The execution and delivery of this Agreement and
        the consummation of the Merger and the other transactions contemplated
        hereby have been duly authorized by all necessary corporate action on
        the part of STAR, subject to the approval by the stockholders of STAR of
        this Agreement and the Merger and the other transactions contemplated
        hereby by the Required STAR Vote. This Agreement has been duly executed
        and delivered by STAR and constitutes a valid and binding agreement of
        STAR, enforceable against it in accordance with its terms, except to the
        extent that its enforceability may be limited by applicable bankruptcy,
        insolvency, reorganization, moratorium or other laws affecting the
        enforcement of creditors' rights generally or by general equitable
        principles (regardless of whether such enforceability is considered in a
        proceeding in equity or at law).

             (2) Subject to the approval by the stockholders of STAR of this
        Agreement, the Merger and the other transactions contemplated hereby by
        the Required STAR Vote, the execution and delivery of this Agreement by
        STAR does not, and the consummation by STAR of the Merger and the other
        actions contemplated hereby will not, conflict with, or result in a
        Violation of: (A) any provision of the certificate of incorporation or
        bylaws of STAR or a Shareholder or any Subsidiary of STAR or (B) except
        as would not have a Material Adverse Effect on STAR, subject to
        obtaining or making the consents, approvals, orders, authorizations,

        below, any loan or credit agreement, note, mortgage, bond, indenture,
        lease, or other agreement, obligation, instrument, permit, concession,
        franchise, license, judgment, order, decree, statute, law, ordinance,
        rule or regulation applicable to STAR, any Subsidiary of STAR or their
        respective properties or assets.

             (3) No consent, approval, order or authorization of, or
        registration, declaration or filing with, any Governmental Entity is
        required by or with respect to STAR or any Subsidiary of
                                      A-13
<PAGE>   315

        STAR in connection with the execution and delivery of this Agreement by
        STAR, or the consummation of the Merger and the other transactions
        contemplated hereby, except the Necessary Consents and such consents,
        approvals, orders, authorizations, registrations, declarations and
        filings the failure of which to make or obtain would not have a Material
        Adverse Effect on STAR.

          (d) Reports and Financial Statements.

             (1) STAR has filed all required registration statements,
        prospectuses, reports, schedules, forms, statements and other documents
        required to be filed by it under the federal securities laws with the
        SEC since January 1, 1998 (collectively, including all exhibits thereto,
        the "STAR SEC Reports"). No Subsidiary of STAR is required to file any
        form, report, registration statement or prospectus or other document
        with the SEC not otherwise filed with an STAR SEC Report. As of the
        respective times such documents were filed or, as applicable, became
        effective, or as subsequently amended, the STAR SEC Reports complied as
        to form and content, in all material respects, with the requirements of
        the Securities Act and the Exchange Act, as the case may be, and the
        rules and regulations promulgated thereunder, and, taken as a whole, the
        STAR SEC Reports do 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. Each of the financial
        statements (including the related notes) included in the STAR SEC
        Reports (or, if amended or superseded by a filing prior to the date of
        this Agreement, then on the date of such filing) presents fairly, in all
        material respects, the consolidated financial position and consolidated
        results of operations and cash flows of STAR and its Subsidiaries as of
        the respective dates or for the respective periods set forth therein,
        all in conformity with GAAP consistently applied during the periods
        involved except as otherwise noted therein, and subject, in the case of
        the unaudited interim financial statements, to normal and recurring
        year-end adjustments that have not been and are not expected to be
        material in amount. All of such STAR SEC Reports, as of their respective
        dates (or as of the date of any amendment to the respective STAR SEC
        Report filed prior to the date of this Agreement), complied or will

        contributed to by STAR or any other employer (a "STAR Affiliate") which,

        ERISA and the Code), except where the failure to comply with such
        obligations would not result in a Material Adverse Effect on STAR. Each
        STAR Employee Benefit Plan that is intended to qualify under Code
        Section 401(a) has received a favorable determination letter (or other
        ruling indicating its tax-qualified status) from the IRS, and the IRS
        has not threatened or taken any action to revoke any favorable
        determination letter issued with respect to any such STAR Employee

        copies of all of the current documents relating to the STAR Employee

        5500 annual reports (including all schedules thereto), summary plan

        WAXS, no plan amendments have been adopted and no such amendments or
        changes shall be adopted or made prior to the Closing Date without
        WAXS's approval, except as required by applicable law after the date
        hereof.

             (4) Neither STAR nor any STAR Affiliate has any agreement,
        arrangement, commitment or understanding to create any additional STAR
        Employee Benefit Plans or to continue, modify, change or terminate any
        existing STAR Employee Benefit Plans that could have a Material Adverse
        Effect on STAR.

        the Pension Benefit Guaranty Corporation or any other federal or state
        agency or (ii) is liable for any federal, state, local or foreign taxes
        that would have a Material Adverse Effect on STAR. Except for such
        liabilities that would not have a Material Adverse Effect on STAR, there
        is no transaction in connection with which STAR or any STAR Affiliate
        could be subject to either a civil penalty assessed pursuant to ERISA
        Section 502, a tax imposed by Code Section 4975 or liability for a
        breach of fiduciary responsibility under ERISA.

             (6) Other than routine claims for benefits payable to participants
        or beneficiaries in accordance with the terms of the STAR Employee
        Benefit Plans, or relating to qualified domestic relations orders (as
        defined in Section 414(p) of the Code), there are no claims, pending or
        threatened, by any participant or beneficiary against any of the STAR
        Employee Benefit Plans or any fiduciary of any of the STAR Employee
        Benefit Plans that could have a Material Adverse Effect on STAR.

             (7) Neither STAR nor any STAR Affiliate has at any time maintained,
        sponsored or contributed to any "pension plan" as defined in ERISA
        Section 3(2) which is subject to Title IV of ERISA or contributed to any
        pension plan which is a "multiemployer plan" as defined in ERISA Section
        3(37)(A).

        be accelerated, (iii) amounts will become immediately payable, and/or
        (iv) the immediate funding for any benefits is required, upon the

        3.2(j)(8) of the STAR Disclosure Schedule sets forth an estimate of the
        total value and/or cost of any such change in control benefits and/or
        funding and the time periods in which such payments must be made and/or
        funding obligations must be met, including but not limited to the value
        and/or costs of any gross up payments for tax purposes.

             (9) To the Knowledge of STAR, no key employee, or group of
        employees of STAR has any plans to terminate employment with STAR other

     or otherwise sell or agree to sell any assets (other than the sale of
     assets used in the operations of the business of STAR and its Subsidiaries
     in the ordinary course; provided, however, STAR may enter into a definitive
     agreement for (and consummate) the PT-1 Sale on terms and conditions which
     would satisfy the condition set forth in Section 6.2(h) hereof).

          (g) Investments; Indebtedness.  STAR shall not, and shall not permit
     any of its Subsidiaries to, (i) make any loans, advances or capital

     pursuant to any contract or other legal obligation of STAR or any of its
     Subsidiaries existing at the date hereof or (ii) create, incur, assume or

     existence on the date hereof or in the ordinary course of business
     consistent with past practice, in each case as such credit facilities,
     indentures and other arrangements may be amended, extended, modified,
     refunded, renewed or refinanced after the date hereof.

          (h) Compensation.  Other than as contemplated by Section 4.1(h) of the
     STAR Disclosure Schedule, STAR shall not increase the amount of

     the ordinary course of business consistent with past practice.

          (j) Certain Agreements.  STAR shall not, and shall not permit any of
     its Subsidiaries to, enter into any agreement or arrangement that limits or
     otherwise restricts STAR or any of its Subsidiaries or any of their
     respective affiliates or any successor thereto, or that could, after the
     Effective Time, limit or restrict WAXS or the Surviving Corporation or any
     of their respective affiliates or any successor thereto, from engaging or
     competing in any line of business or, in any geographic area which
     agreement or arrangement would reasonably be expected to have a Material

Effective Time, STAR shall exercise, consistent with the terms and conditions of
this Agreement, complete control and supervision over its operations.

                                   ARTICLE V

                             ADDITIONAL AGREEMENTS

     5.1 Preparation of Proxy Statement: Stockholders Meetings.

          (a) As promptly as reasonably practicable following the date hereof,
     WAXS and STAR shall prepare (in form and substance reasonably satisfactory
     to each of WAXS and STAR) and file with the SEC proxy materials which shall
     constitute the joint proxy statement and prospectus in connection with the
     WAXS Stockholders Meeting and the STAR Stockholders Meeting (such proxy
     statement and prospectus, and any amendments or supplements thereto, the
     "Joint Proxy Statement/Prospectus") and WAXS shall prepare (in form and
     substance reasonably satisfactory to each of WAXS and STAR) and file a
     registration statement on Form S-4 with respect to the issuance of WAXS
     Common Stock in the Merger (the "Registration Statement"). The Joint Proxy
     Statement/Prospectus will be included in and will constitute a part of the
     Registration Statement as WAXS's prospectus. The Registration Statement and
     the Joint Proxy Statement/Prospectus shall comply as to form in all
     material respects with the applicable provisions of the Securities Act and
     the Exchange Act and the rules and regulations thereunder. Each of WAXS and
     STAR shall use reasonable efforts to have the Registration Statement
     declared effective by the SEC as promptly as reasonably practicable after
     filing with the SEC and to keep the Registration Statement effective as
     long as is necessary to consummate the Merger and the actions contemplated
     thereby. WAXS and STAR shall, as promptly as practicable after receipt
     thereof, provide the other party copies of any written comments and advise
     the other party of any oral comments, with respect to the Joint Proxy
     Statement/Prospectus received from the SEC. WAXS will provide STAR with a
     reasonable opportunity to review and comment on any amendment or supplement
     to the Registration Statement prior to filing such with the SEC, and will
     provide STAR with a copy of all such filings made with the SEC.
     Notwithstanding any other provision herein to the contrary, no amendment or
     supplement (including by incorporation by reference) to the Joint Proxy
     Statement/Prospectus or the Registration Statement shall be made without
     the approval of both parties, which approval shall not be unreasonably
     withheld or delayed; provided, that with respect to documents filed by a
     party which are incorporated by reference in the Registration Statement or
     Joint Proxy Statement/Prospectus, this right of approval shall apply only
     with respect to information relating to the other party or its business,
     financial condition or results of operations. WAXS will use reasonable
     efforts to cause the Joint Proxy Statements/Prospectus to be mailed to
     WAXS's stockholders, and STAR will use reasonable efforts to cause the
     Joint Proxy Statement/Prospectus to be mailed to STAR's stockholders, in
     each case as promptly as practicable after the Registration Statement is
     declared effective under the Securities Act. WAXS shall also take any
     action (other than qualifying to do business in any jurisdiction in which
     it is not now so qualified or to file a general consent to service of
     process) required to be taken under any applicable state securities laws in
     connection with the issuance of WAXS Common Stock and STAR shall furnish
     all information concerning STAR and the holders of STAR Common Stock as may
     be reasonably requested in connection with any such action. Each party will
     advise the other party, promptly after it receives notice thereof, of the
     time when the Registration Statement has become effective, the issuance of
     any stop order, the suspension
                                      A-21
<PAGE>   323

     of the qualification of the WAXS Common Stock issuable in connection with
     the Merger for offering or sale in any jurisdiction, or any request by the
     SEC for amendment of the Joint Proxy Statement/Prospectus or the
     Registration Statement. If at any time prior to the Effective Time any
     information relating to WAXS or STAR, or any of their respective
     affiliates, officers or directors, should be discovered by WAXS or STAR
     which should be set forth in an amendment or supplement to any of the
     Registration Statement or the Joint Proxy Statement/Prospectus so that any
     of such documents would not include any misstatement of a material fact or
     omit to state any material fact necessary to make the statements therein,
     in light of the circumstances under which they were made, not misleading,
     the party which discovers such information shall promptly notify the other
     party hereto and, to the extent required by law, rules or regulations, an
     appropriate amendment or supplement describing such information shall be
     promptly filed with the SEC and disseminated to the stockholders of WAXS
     and STAR.

          (b) Subject to Section 5.4, STAR shall, as promptly as reasonably
     practicable following the execution of this Agreement, duly take all lawful
     action to call, give notice of, convene and hold a meeting of its
     stockholders (the "STAR Stockholders Meeting") (which meeting the parties
     intend to be held no later than thirty (30) days following the date on
     which the Registration Statement has been declared effective by the SEC)
     for the purpose of obtaining the Required STAR Vote with respect to the
     actions contemplated by this Agreement and shall take all lawful action to
     solicit the adoption of this Agreement by the Required STAR Vote. Subject
     to Section 5.4, the Board of Directors of STAR shall recommend adoption of
     this Agreement by the stockholders of STAR to the effect as set forth in
     Section 3.2(f), and shall not withdraw, modify or materially qualify in any
     manner adverse to WAXS such recommendation or take any action or make any
     statement in connection with the STAR Stockholders Meeting materially
     inconsistent with such recommendation (collectively, an "Adverse Change in
     the STAR Recommendation"); provided, however, that the foregoing shall not
     prohibit accurate disclosure of factual information regarding the business,
     financial condition or results of operations of WAXS or STAR or the fact
     that an Acquisition Proposal has been made, the identity of the party
     making such proposal or the material terms of such proposal (provided, that
     the Board of Directors of STAR does not withdraw, modify or materially
     qualify in any manner adverse to WAXS its recommendation) in the
     Registration Statement or the Joint Proxy Statement/Prospectus, to the
     extent such information, facts, identity or terms is required to be
     disclosed therein under applicable law.

          (c) WAXS shall, as promptly as reasonably practicable following the
     execution of this Agreement, duly take all lawful action to call, give
     notice of, convene and hold a meeting of its stockholders (the "WAXS
     Stockholders Meeting") (which meeting the parties intend to be held no
     later than thirty (30) days following the date on which the Registration
     Statement has been declared effective by the SEC) for the purpose of
     obtaining the Required WAXS Vote with respect to the transactions
     contemplated by this Agreement and shall take all lawful action to solicit
     the approval of the transactions contemplated hereby by the Required WAXS
     Vote. The Board of Directors of WAXS shall recommend approval of the
     transactions contemplated hereby by the stockholders of WAXS to the effect
     as set forth in Section 3.1(f), and shall not withdraw, modify or
     materially qualify in any manner adverse to STAR such recommendation or
     take any action or make any statement in connection with the WAXS
     Stockholders Meeting materially inconsistent with such recommendation;
     provided, however, that the foregoing shall not prohibit accurate
     disclosure of factual information regarding the business, financial
     condition or operations of WAXS or STAR.

     5.2 Access to Information.  Upon reasonable notice, each of STAR and WAXS
shall (and shall cause its Subsidiaries to) afford to the officers, employees,
accountants, counsel, financial advisors and other representatives of the other
party hereto reasonable access during normal business hours, during the period
prior to the Effective Time, to all its properties, books, contracts,
commitments, records, officers and employees and, during such period, each of
STAR and WAXS shall (and shall cause its Subsidiaries to) furnish promptly to
the other party hereto (a) a copy of each report, schedule, registration
statement and other document filed, published, announced or received by it
during such period pursuant to the
                                      A-22
<PAGE>   324

requirements of federal or state securities laws, as applicable (other than
documents which such party is not permitted to disclose under applicable law),
and (b) consistent with its legal obligations, all other information concerning
it and its business, properties and personnel as such other party may reasonably
request; provided, however, that either STAR or WAXS may restrict the foregoing
access to the extent that any law, treaty, rule or regulation of any
Governmental Entity applicable to such party requires such party or its
Subsidiaries to restrict access to any properties or information. The parties
will hold any such information which is non-public in confidence to the extent
required by, and in accordance with, the provisions of the Confidentiality
Agreement, dated December 17, 1999, between STAR and WAXS (the "Confidentiality
Agreement"). Any investigation by WAXS or STAR shall not affect the
representations and warranties made herein of STAR or WAXS, as the case may be.

     5.3 Reasonable Efforts.

          (a) Subject to the terms and conditions of this Agreement, each party
     will use 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 the Merger and the other
     transactions contemplated by this Agreement as soon as practicable after
     the date hereof, including (i) preparing and filing as promptly as
     practicable all documentation to effect all necessary applications,
     notices, petitions, filings, and other documents and to obtain as promptly
     as practicable all consents, waivers, licenses, orders, registrations,
     approvals, permits and authorizations necessary or advisable to be obtained
     from any third party and/or any Governmental Entity in order to consummate
     the Merger or any of the other transactions contemplated by this Agreement
     and (ii) taking all reasonable steps as may be necessary to obtain all such
     material consents, waivers, licenses, registrations, permits,
     authorizations, tax rulings, orders and approvals. The parties each shall
     keep the other apprised of the status of matters relating to completion of
     the transactions contemplated hereby, including promptly furnishing the
     other with copies of notices or other communications received by it or any
     of its Subsidiaries or affiliates from any Governmental Entity or third
     party with respect to the Merger or any of the other transactions
     contemplated by this Agreement, in each case, to the extent permitted by
     law or regulation or any applicable confidentiality agreements existing on
     the date hereof.

          (b) Promptly following execution of this Agreement, STAR and WAXS
     shall promptly prepare and file any required notifications with the United
     States Department of Justice and the Federal Trade Commission as required
     by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
     (the "HSR Act"). The parties shall cooperate with each other in connection
     with the preparation of such notifications and related matters, including
     sharing information concerning sales and ownership and such other
     information as may be needed to complete such notification, and providing a
     copy of such notifications to the other prior to filing; provided, that
     WAXS and STAR shall have the right to redact any dollar revenue information
     from the copies of such notifications provided to the other parties. The
     parties shall keep all information about the other obtained in connection
     with the preparation of such notification confidential pursuant to the
     terms of the Confidentiality Agreement. Each Person shall pay the filing
     fee required under the regulations promulgated pursuant to the HSR Act with
     respect to its own filing thereunder.

     5.4 Acquisition Proposals.  Without the prior written consent of WAXS,
pending the Effective Time or earlier termination of this Agreement pursuant to
Section 7.1, STAR agrees that neither it nor any of its Subsidiaries shall, and
that it shall use its reasonable efforts to cause its employees, officers,
directors, affiliates, agents and representatives (including any investment
banker, financial advisor, attorney or accountant retained by any of them) not
to, directly or indirectly, initiate, solicit, encourage or knowingly facilitate
(including by way of furnishing information or engaging in discussions or
negotiations) any inquiries or the making of any proposal or offer with respect
to a merger, reorganization, share exchange, consolidation, business
combination, recapitalization, liquidation, dissolution or similar action
involving STAR, or any purchase or sale of a material portion of the assets of
(including stock of Subsidiaries) of STAR, taken as a whole, or any purchase or
sale of, or tender or exchange offer for, a material portion of the equity
securities of STAR (any such proposal or offer being hereinafter referred to as
an "Acquisition Proposal"). STAR further agrees that neither it nor any of its
Subsidiaries shall, and that it shall use its
                                      A-23
<PAGE>   325

reasonable efforts to cause it and its Subsidiaries' officers, directors,
affiliates, employees, agents and representatives (including any investment
banker, financial advisor, attorney or accountant retained by it or any of its
Subsidiaries) not to, directly or indirectly, have any discussion with or
provide any confidential information or data to any Person relating to an
Acquisition Proposal, or engage in any negotiations concerning an Acquisition
Proposal, or knowingly facilitate any effort or attempt to make or implement an
Acquisition Proposal or accept an Acquisition Proposal. STAR agrees that it and
its Subsidiaries will, and will cause its officers, directors, affiliates,
employees, agents and representatives to, immediately cease and cause to be
terminated any activities, discussions or negotiations existing as of the date
of this Agreement with any parties conducted heretofore with respect to any
Acquisition Proposal. STAR agrees that it will promptly inform its directors,
officers, affiliates, key employees, agents and representatives of the
obligations undertaken in this Section 5.4. Notwithstanding anything contained
in this Section 5.4 or otherwise in this Agreement to the contrary, STAR or its
Board of Directors shall be permitted to (A) in response to an unsolicited bona
fide written Acquisition Proposal by any Person, recommend approval of such an
unsolicited bona fide written Acquisition Proposal to its stockholders or effect
an Adverse Change in the STAR Recommendation or (B) engage in any discussions or
negotiations with, or provide any information to, any person in response to an
unsolicited bona fide written Acquisition Proposal by any such Person, if and
only to the extent that, in any such case as is referred to in clause (A) or
(B), (i) the STAR Stockholders Meeting shall not have occurred, (ii) its Board
of Directors (x) in the case of clause (A) above, concludes in good faith that
such Acquisition Proposal constitutes a Superior Proposal (as defined in Section
8.12) and terminates this Agreement pursuant to Section 7.1 (h) or (y) in the
case of clause (B) above concludes in good faith that such Acquisition Proposal
could reasonably be expected to result in a Superior Proposal, (iii) prior to
providing any information or data to any Person in connection with an
Acquisition Proposal by any such Person, its Board of Directors receives from
such Person an executed confidentiality agreement containing confidentiality
terms at least as stringent as those contained in the Confidentiality Agreement,
and (iv) prior to providing any information or data to any Person or entering
into discussions or negotiations with any such Person regarding such Acquisition
Proposal, its Board of Directors notifies WAXS promptly of such inquiries,
proposals or offers received by, any such information requested from, or any
such discussions or negotiations sought to be initiated or continued with, any
of its representatives indicating, in connection with such notice, the name of
such Person and the material terms and conditions of any inquiries, proposals or
offers. STAR agrees that it will promptly keep WAXS informed of the status and
terms of any such proposals or offers and the status and terms of any such
discussions or negotiations. STAR agrees that it will, and will cause its
officers, directors and representatives to, immediately cease and cause to be
terminated any activities, discussions or negotiations existing as of the date
of this Agreement with any parties conducted heretofore with respect to any
Acquisition Proposal. STAR agrees that it will promptly inform its directors,
officers, key employees, agents and representative of the obligations undertaken
in this Section 5.4. Nothing in this Section 5.4 shall (x) permit STAR or WAXS
to terminate this Agreement (except as specifically provided in Article VII
hereof) or (y) affect any other obligation of STAR or WAXS under this Agreement.

     5.5 Fees and Expenses.  All Expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be paid by the party
incurring such Expenses. As used in this Agreement, "Expenses" includes all
out-of-pocket expenses (including all fees and expenses of counsel, accountants,
investment bankers, experts and consultants to a party hereto and its
affiliates) incurred by a party or on its behalf in connection with or related
to the authorization, preparation, negotiation, execution and performance of
this Agreement and the transactions contemplated hereby.

     5.6 Public Announcements.  Neither WAXS nor STAR shall, without the prior
consent of the other party, issue a press release or any other public statement
with respect to this Agreement or the transactions contemplated hereby except
pursuant to a joint communications plan, unless otherwise required by applicable
law or by obligations pursuant to any listing agreement with, or rules of, any
securities exchange, in which case the parties shall use reasonable efforts to
consult with each other before issuing any press release or otherwise making any
public statement with respect to this Agreement or the transactions contemplated
hereby.
                                      A-24

     5.7 Listing.  So long as WAXS Common Stock is quoted on the Nasdaq or
listed on any national securities exchange, WAXS, prior to the Effective Time,
will cause to be quoted or listed, upon official notice of issuance, and keep
quoted or listed on such system or exchange, all WAXS Common Stock issuable
pursuant to Article I hereof.

     5.8 Termination of Tax Sharing Agreement.  As of the Effective Time, STAR
shall cause all Tax Sharing Agreements to which STAR or any of its Subsidiaries
is a party to be terminated and of no further force and effect after the
Effective Time, thereby extinguishing any rights or obligations of any party
thereunder.

     5.9 Management Services.  Subject to obtaining any necessary regulatory or
third party consents and to the extent permitted under applicable law, WAXS and
STAR intend to enter into a management agreement pursuant to which WAXS will
provide, under the supervision and direction of the STAR board of directors,
certain management services to STAR. Neither party shall have any obligation
under this Section 5.9 and the provision of the foregoing services shall be
subject to the negotiation of a definitive agreement satisfactory to each of
WAXS and STAR in its sole discretion.

     5.10 New Director of WAXS.  WAXS shall take all appropriate action such
that, immediately following the Effective Time, and without further action by
WAXS, one (1) designee of STAR shall be elected to the Board of Directors of
WAXS. Such STAR designee shall be Christopher E. Edgecomb, or such other person
designated by STAR and agreed to by WAXS prior to the Effective time.

     5.11 Further Assurances.  At and after the Effective Time, the officers and
directors of the Surviving Corporation will be authorized to execute and
deliver, in the name and on behalf of STAR or Merger Sub, any deeds, bills of
sale, assignments or assurances and to take and do, in the name and on behalf of
STAR or Merger Sub, any other actions and things to vest, perfect or confirm of
record or otherwise in the Surviving Corporation any and all rights, properties,
or assets acquired or to be acquired by the Surviving Corporation as a result
of, or in connection with, the Merger.

     5.12 Directors' and Officers' Indemnification and Insurance.

          (a) From the Effective Time through the sixth (6th) anniversary of the
     date on which the Effective Time occurs, WAXS shall indemnify and hold
     harmless each present (as of the Effective Time) or former officer or
     director of STAR and its Subsidiaries (the "Indemnified Parties"), against
     all claims, losses, liabilities, damages, judgments, fines and reasonable
     fees, costs and expenses, including attorneys' fees and disbursements
     (collectively, "Costs"), incurred in connection with any claim, action,
     suit, proceeding or investigation, whether civil, criminal, administrative
     or investigative, arising out of or pertaining to (i) the fact that the
     Indemnified Party is or was an officer or director of STAR or any of its
     Subsidiaries or (ii) matters existing or occurring at or prior to the
     Effective Time (including this Agreement and the transactions and actions
     contemplated hereby), whether asserted or claimed prior to, at or after the
     Effective Time, to the fullest extent permitted under applicable law;
     provided that no Indemnified Party may settle any such claim without the
     prior approval of WAXS (which approval shall not be unreasonably withheld
     or delayed). Each Indemnified Party will be entitled to advancement of
     expenses incurred in the defense of any claim, action, suit, proceeding or
     investigation from WAXS within ten (10) business days of receipt by WAXS
     from the Indemnified Party of a request therefor; provided that any person
     to whom expenses are advanced provides an undertaking, to the extent
     required by the DGCL, to repay such advances if it is ultimately determined
     that such person is not entitled to indemnification.

          (b) WAXS shall maintain, at no expense to the beneficiaries, in effect
     for six years from the Effective Time the current policies of the
     directors' and officers' liability insurance maintained by STAR with
     respect to matters existing or occurring at or prior to the Effective Time
     (including the transactions contemplated by this Agreement); provided that
     WAXS may substitute therefor policies of at least the same coverage
     containing terms and conditions which are not materially less advantageous
     to any beneficiary thereof; and provided, further, that in no event shall
     WAXS be

                                      A-25
<PAGE>   327

     required to pay annual premiums for such insurance in excess of 125% of the
     annual premiums currently paid by STAR for such insurance.

          (c) Notwithstanding anything herein to the contrary, if any claim,
     action, suit, proceeding or investigation (whether arising before, at or
     after the Effective Time) is made against any Indemnified Party, on or
     prior to the sixth (6th) anniversary of the Effective Time, the provisions
     of this Section 5.12 shall continue in effect until the final disposition
     of such claim, action, suit, proceeding or investigation.

          (d) The covenants contained in this Section 5.12 are intended to be
     for the benefit of, and shall be enforceable by, each of the Indemnified
     Parties and their respective heirs and legal representatives and shall not
     be deemed exclusive of any other rights to which an Indemnified Party is
     entitled, whether pursuant to law, contract or otherwise.

          (e) In the event that the Surviving Corporation or any of its
     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 or conveys all or substantially
     all of its properties and assets to any Person, then, and in each such
     case, proper provision shall be made so that the successors or assigns of
     the Surviving Corporation or the purchaser of such properties and assets
     shall succeed to the obligations set forth in this Section 5.12.

     5.13 Confidentiality.  The parties each agree that the Confidentiality
Agreement shall continue in full force and effect until the Effective Time, and

     representations and warranties speak as of another date, in which case any

     chief financial officer of STAR to such effect.

          (b) Performance of Obligations of STAR.  STAR shall have performed or

     notices to any Governmental Entity required to consummate the Merger and
     the other transactions contemplated hereby, or of any other third party
     required of STAR or any of its Subsidiaries to consummate the Merger and
     the other transactions contemplated hereby, the failure of which to be
     obtained or taken would have a Material Adverse Effect on WAXS or the
     Surviving Corporation, shall have been obtained; provided, however, that
     the provisions of this Section 6.2(c) shall not be available to WAXS, if
     its failure to fulfill its obligations pursuant to Section 5.3 shall have
     been the cause of, or shall have resulted in, the failure to obtain such
     consent or approval.

          (d) No Material Change.  STAR and its Subsidiaries, taken as a whole,
     shall not have suffered, since the date hereof, a Material Adverse Effect,
     other than any change, circumstance or effect relating (i) to the economy
     or financial markets in general, (ii) in general to the industries in which
     STAR operates and not specifically relating to STAR or (iii) the trading
     price of STAR Common Stock.

          (e) Opinion of Counsel to STAR.  WAXS shall have received from Riordan
     & McKinzie an opinion, dated the Closing Date, in form and substance
     reasonably satisfactory to WAXS.

     adopted or promulgated, and no temporary restraining order, preliminary or
     permanent injunction or other order issued by a court or other Governmental
     Entity of competent jurisdiction shall be in effect (i) having the effect
     of making the Merger illegal or otherwise prohibiting consummation of the
     Merger or (ii) which otherwise would have a Material Adverse Effect on WAXS
     or the Surviving Corporation; provided, however, that the provisions of
     this Section 6.2(f) shall not be available to WAXS if its failure to
     fulfill its obligations pursuant to Section 5.3 shall have been the cause
     of, or shall have resulted in any such order or injunction.

          (g) Dissenters' Rights.  STAR shall have complied with all procedures
     and requirements applicable to it under Section 262 of the DGCL, the period
     for exercising dissenters' rights of appraisal pursuant to the DGCL in
     connection with the Merger shall have expired, and holders of less than one
     percent (1%) of the shares of STAR Common Stock issued and outstanding
     immediately prior to the Closing shall have exercised such dissenters'
     rights of appraisal, and WAXS shall have received a certificate from an
     officer of STAR to all such effects.

          (h) Sale of PT-1.  STAR shall have consummated the sale of the capital
     stock of PT-1 Communications, Inc. ("PT-1"), or the assets of PT-1 on a
     substantially equivalent basis, for Net PT-1 Sale Proceeds (as defined in
     Section 8.12 ) of at least $150,000,000 pursuant to an agreement in form
     and substance reasonably satisfactory to WAXS (the "PT-1 Sale"); provided,
     however, if
                                      A-27
<PAGE>   329

     (i) the PT-1 Sale has not been consummated prior to the Closing Date, (but
     STAR has entered into a definitive agreement, in form and substance
     satisfactory to WAXS, for the PT-1 Sale) and (ii) WAXS determines in its
     sole discretion to waive compliance with this Section 6.2(h) and proceed
     with the Merger, then WAXS and STAR agree that in such event, they shall
     amend this Agreement to provide that (A) the formula used to determine the
     Exchange Ratio shall be modified by deleting "Z" therefrom and (B) a holder
     of STAR Common Stock and STAR Stock Options immediately prior to the
     Effective Time shall have a right to receive such holder's pro rata share
     of an aggregate number of additional "contingent" shares of WAXS Common
     Stock, if and when the PT-1 Sale is consummated pursuant to such definitive
     agreement (or, in the case of a holder of STAR Stock Option, when such
     option is exercised), equal to the PT-1 Excess Proceeds divided by twenty
     (20) (the "Contingent Shares") and that the provisions of any such
     amendment to this Agreement concerning the issuance of such Contingent
     Shares will satisfy the requirements of Section 3.03 of IRS Revenue
     Procedure 77-37, as it has been amplified and superseded, which established
     the circumstances under which the Internal Revenue Service previously
     issued advanced rulings on contingent stock arrangements in mergers
     intended to qualify as "reorganizations" under Section 368(a) of the Code.

          (i) STAR shall have provided evidence satisfactory to WAXS that any
     and all obligations of STAR (or any of its affiliates) relating to or
     arising in connection with the China-U.S. Cable Network were fully
     satisfied by the reclamation of STAR's capacity in such network and neither
     STAR nor any of its affiliates has any further obligation or liability with
     respect thereto, including without limitation payment of the amounts
     claimed and owing by STAR according to that letter dated January 11, 2000
     from Kou Yinsen, Director, CBP to Jim Kolsrud.

     representations and warranties speak as of another date, in which case any
     such representations and warranties shall be true and correct as of such
     date), except where any failures to be true and correct would not have a
     Material Adverse Effect on WAXS, and STAR shall have received a certificate
     of the chief executive officer and the chief financial officer of WAXS to
     such effect.

          (b) Performance of Obligations of WAXS.  WAXS shall have performed or
     complied in all material respects with all material agreements and
     covenants required to be performed by it under this Agreement at or prior
     to the Closing Date, and STAR shall have received a certificate of the
     chief executive officer and the chief financial officer of WAXS to such
     effect.

          (c) Consents and Approvals.  Other than the filing provided for under
     Section 1.3, all consents, approvals and actions of, filings with and
     notices to any Governmental Entity required to consummate the Merger and
     the other transactions contemplated hereby, or of any other third party
     required of WAXS or any of its Subsidiaries to consummate the Merger and
     the transactions contemplated hereby, the failure of which to be obtained
     or taken would have a Material Adverse Effect on WAXS, shall have been
     obtained; provided, however, that the provisions of this Section 6.3(c)
     shall not be available to STAR if its failure to fulfill any of its
     obligations pursuant to Section 5.3 shall have been the cause of, or shall
     have resulted in, the failure to obtain such consent or approval.

          (d) No Material Change.  WAXS shall not have suffered, since the date
     hereof, a Material Adverse Effect, other than any change, circumstance or
     effect relating (i) to the economy or financial markets in general, (ii) in
     general to the industries in which WAXS operates and not specifically
     relating to WAXS or (iii) the trading price of WAXS Common Stock.

          (e) Opinion of Counsel to WAXS.  STAR shall have received from Long
     Aldridge & Norman LLP an opinion, dated the Closing Date, in form and
     substance reasonably satisfactory to STAR.

          (f) No Injunctions or Restraints; Illegality.  No laws shall have been
     adopted or promulgated, and no temporary restraining order, preliminary or
     permanent injunction or other order issued by a court or other Governmental
     Entity of competent jurisdiction shall be in effect (i) having the effect
     of making the Merger illegal or otherwise prohibiting consummation of the
     Merger or (ii) which otherwise would have a Material Adverse Effect on WAXS
     after giving effect to the Merger; provided, however, that the provisions
     of this Section 6.3(g) shall not be available to STAR if its failure to
     fulfill its obligations pursuant to Section 5.3 shall have been the cause
     of, or shall have resulted in any such order or injunction.

          (g) Exchange Fund.  An officer of the Exchange Agent shall have
     certified in writing to STAR that the deposit required to be made by WAXS
     into the Exchange Fund pursuant to Section 2.1 has been made in connection

                           TERMINATION AND AMENDMENT

     7.1 Termination.  This Agreement may be terminated at any time prior to the
Effective Time, by action taken or authorized by the Board of Directors of the
terminating party or parties:

          (a) By mutual written consent of WAXS and STAR;

          (b) By either WAXS or STAR, if the other party shall have failed to
     comply in any material respect with any of its material covenants or
     agreements contained in this Agreement, which failure to so comply has not
     been cured within ten (10) business days following receipt by such other
     party of written notice of such failure to comply; provided, however, that
     if any such breach is curable by the breaching party through the exercise
     of the breaching party's reasonable efforts and for so long as the
     breaching party shall be so using its reasonable efforts to cure such
     breach, the non-breaching party may not terminate this Agreement pursuant
     to this paragraph; and provided, further, that no party shall have the
     right to terminate this Agreement pursuant to this Section 7.1(b) if such
     party is then failing to comply in any material respect with any of its
     covenants or agreements contained in this Agreement;

          (c) By either WAXS or STAR, if there has been a breach by the other
     party of any representations or warranties, which breach has not been cured
     within ten (10) business days following receipt by such other party of
     written notice of such failure to comply; provided, however, that if any
     such breach is curable by the breaching party through the exercise of the
     breaching party's reasonable efforts and for so long as the breaching party
     shall be so using reasonable efforts to cure such breach, the non-breaching
     party may not terminate this Agreement pursuant to this paragraph; and
     provided further, that this provision shall not apply to such breaches
     which would not have a Material Adverse Effect on WAXS or the Surviving
     Corporation;

          (d) By either STAR or WAXS, if the Effective Time shall not have
     occurred on or before September 30, 2000 (the "Termination Date");
     provided, however, that the right to terminate this Agreement under this
     Section 7.1(d) shall not be available to any party whose action or failure
     to fulfill any obligation under this Agreement has been the cause of, or
     resulted in, the failure of the Effective Time to occur on or before the
     Termination Date and any such action or failure constitutes a breach of
     this Agreement by such party;

          (e) By either STAR or WAXS if any Governmental Entity (i) shall have
     issued an order, decree or ruling or taken any other action (which the
     parties shall have used their reasonable efforts to resist, resolve or
     lift, as applicable, in accordance with Section 5.3) permanently
     restraining, enjoining or otherwise prohibiting the transactions
     contemplated by this Agreement, and such order, decree, ruling, or other
     action shall have become final and nonappealable or (ii) shall have failed

     issue an order, decree or ruling or to take any other action (which order,
     decree, ruling or other action the parties shall have used their reasonable
     efforts to obtain, in accordance with Section 5.3), which, in the case of
     each of (i) and (ii) is necessary to fulfill the conditions set forth in
     Section 6.2(f) with respect to WAXS or Section 6.3(g) with respect to STAR,
     and such denial of a request to issue such order, decree, ruling or take
     such other action shall have become final and nonappealable; provided,
     however, that the right to terminate this Agreement under this Section
     7.1(e) shall not be available to any party whose action or failure to
     fulfill any obligation under this Agreement has been the cause of such
     action or inaction and any such action or failure constitutes a breach of
     this Agreement by such party;

          (f) By WAXS or STAR if the adoption of this Agreement by the
     stockholders of WAXS or the stockholders of STAR shall not have been
     obtained by reason of the failure to obtain the Required WAXS Vote or the
     Required STAR Vote, as applicable, in each case upon the taking of such
     vote at a duly held meeting of stockholders of WAXS or STAR, or at any
     adjournment thereof;

          (g) By WAXS if the Board of Directors of STAR, prior to the Required
     STAR Vote, shall make an Adverse Change in the STAR Recommendation (other
     than in connection with STAR's termination of this Agreement pursuant to
     Section 7.1(b)) or approve or recommend a Superior Proposal pursuant to
     Section 5.4 or shall resolve to take any such actions;

          (h) By STAR, at any time prior to the Required STAR Vote upon three
     (3) business days' prior notice to WAXS, if its Board of Directors shall
     have determined as of the date of such notice that an Acquisition Proposal
     is a Superior Proposal; provided, however, that (i) STAR shall have
     complied with Section 5.4, (ii) prior to such termination, STAR shall, if
     requested by WAXS in connection with a revised proposal by it, negotiate in
     good faith for such three (3) business day period with WAXS and (iii) the
     Board of Directors of STAR shall have concluded in good faith, as of the
     effective date of such termination, after taking into account any revised
     proposal by WAXS during such three (3) business day period, that an
     Acquisition Proposal is a Superior Proposal; and provided, further, that it
     shall be a condition to termination by STAR pursuant to this Section 7.1(h)
     that STAR shall have made the payment of the fee to WAXS pursuant to
     Section 7.2(b);

          (i) By WAXS, if (X) either STAR or any of its material Subsidiaries

     affairs of STAR or any of its material Subsidiaries and, in each case, such
     decree or order shall remain unstayed and in effect for a period of 30
     consecutive days; or

          (j) By WAXS if there has been an Event of Default under the Credit
     Agreement, of even date herewith, between WAXS and STAR.

     7.2 Effect of Termination.

          (a) In the event of any termination of this Agreement by either STAR
     or WAXS, as provided in Section 7.1, this Agreement shall forthwith become
     void and there shall be no liability or obligation on the part of WAXS or
     STAR or their respective officers or directors except with respect to
     Section 3.1(m), Section 3.2(l), the second sentence of Section 5.2, Section
     5.5, Section 5.6, this Section 7.2, and Article VIII, which provisions

                                      A-30
<PAGE>   332

     notwithstanding anything to the contrary contained in this Agreement,
     neither WAXS nor STAR shall be relieved or released from any liabilities or
     damages arising out of its breach of this Agreement;

          (b) If this Agreement is terminated by STAR pursuant to Section

          (c) If this Agreement is terminated by WAXS pursuant to Section
     7.1(g), STAR shall, within three (3) days following such termination, pay
     to WAXS the Termination Fee; and

          (d) If this Agreement is terminated by WAXS or STAR pursuant to
     Section 7.1(f) because STAR's stockholders have failed to adopt this
     Agreement by the Required Star Vote and STAR enters into a definitive
     agreement with respect to a Business Combination within twelve (12) months
     following such termination, then STAR shall pay to WAXS the Termination Fee
     prior to or at the consummation thereof.

     7.3 Amendment.  This Agreement may be amended by STAR and WAXS, by action
taken or authorized by their respective Boards of Directors or representatives
or authorized officers, at any time before or after approval of the matters
presented in connection with the Merger by the stockholders of STAR and WAXS
(including, without limitation, an amendment as described in Section 6.2(h)),
but, after any such approval, no amendment shall be made which by law or in
accordance with the rules of any relevant stock exchange or automatic quotations
system requires further approval by such stockholders without such further
approval. This Agreement may not be amended except by an instrument in writing
signed on behalf of each of STAR and WAXS.

     7.4 Extension, Waiver.  At any time prior to the Effective Time, the

other acts of the other parties hereto, (ii) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto and (iii) waive compliance with any of the agreements or

such extension or waiver shall be valid only if set forth in a written
instrument signed on behalf of such party. The failure of any party to this
Agreement to assert any of its rights under this Agreement or otherwise shall
not constitute a waiver of those rights.

WAXS ("Merger Sub"), and STAR Telecommunications, Inc., a Delaware corporation
("STAR").



                                  WITNESSETH:



     WHEREAS, WAXS, Merger Sub and STAR are parties to that certain Agreement
and Plan of Merger, dated as of February 11, 2000 (the "Merger Agreement"),
pursuant to which STAR will merge with and into Merger Sub;



     WHEREAS, the parties have agreed to make certain amendments to the Merger
Agreement; and



     WHEREAS, capitalized terms used, but not otherwise defined herein, shall
have the meanings given to such terms in the Merger Agreement.



     NOW THEREFORE, in consideration of the mutual covenants contained herein
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties to hereby mutually agree as follows:



          1. Section 1.6(c) of the Merger Agreement is hereby deleted in its
     entirety and replaced with the following:



             "Subject to Section 2.4, each share of STAR Common Stock issued and
        outstanding immediately prior to the Effective Time (other than the
        Dissenter's Shares (as defined in Section 8.12)) shall be converted into
        the right to receive, at the election of WAXS by written notice to STAR
        prior to the Closing, (i) the number of shares of WAXS Common Stock
        obtained by solving for "X" in the following formula (the "Exchange
        Ratio"):



<TABLE>
                        <S>  <C>  <C>    <C>  <C>
                        X    =    7.7319 +    Z
                                  -------------
                                        20
</TABLE>



        or (ii) such number of shares of WAXS Common Stock as shall equal up to
        sixty percent (60%) of the Exchange Ratio and an amount in cash equal up
        to forty percent (40%) of the average closing price of the WAXS Common
        Stock on Nasdaq for the ten (10) trading day period ending at the close
        of trading on the trading day immediately preceding the Closing Date
        multiplied by "X"; provided, however, that WAXS and STAR expressly agree
        that, notwithstanding anything in this Agreement to the contrary, in

        requirement under Treasury Regulation Section 1.368-l(e), in no event
        shall WAXS issue cash for more than forty-five percent (45%) of the

        lieu of fractional shares paid pursuant to Section 2.4 shall be referred
        to herein as the "Merger Consideration."

        that any and all obligations of STAR (or any of its affiliates) relating
        to or arising in connection with the China-U.S. Cable Network were not
        fully satisfied by the reclamation of STAR's capacity in such network
        and that neither STAR nor any of its affiliates has any further
        obligation or liability with respect thereto."



          6. Except as expressly set forth in this Amendment, the Merger
     Agreement shall remain in full force and effect and shall not be deemed to
     have been modified or amended by this Amendment.



          7. This Amendment constitutes the entire understanding of the parties
     with respect to the subject matter hereof, and any other prior or
     contemporaneous agreements, whether written or oral, with respect thereto
     are expressly superseded hereby.



          8. This Amendment may be executed in two or more counterparts, each of
     which shall for all purposes be deemed to be an original and all of which
     shall constitute the same instrument.

                          AGREEMENT AND PLAN OF MERGER


     THIS AGREEMENT AND PLAN OF MERGER, dated as of February 11, 2000 (this
"Agreement"), by and among World Access, Inc., a Delaware corporation ("WAXS"),
CTI Merger Co., a Delaware corporation and wholly-owned subsidiary of WAXS
("Merger Sub"), and Communication TeleSystems International d/b/a WorldxChange
Communications, a California corporation ("CTI").


                              W I T N E S S E T H:

     WHEREAS, the Boards of Directors of CTI and WAXS deem it advisable and in
the best interests of each corporation and its respective stockholders that CTI
and WAXS engage in a business combination in order to advance the long-term
strategic business interests of CTI and WAXS;

     WHEREAS, the combination of CTI and WAXS shall be effected by the terms of
this Agreement through a merger as outlined below (the "Merger");

     WHEREAS, in furtherance thereof, the respective Boards of Directors of CTI,
Merger Sub and WAXS have approved the Merger, upon the terms and subject to the
conditions set forth in this Agreement, pursuant to which each share of common
stock, par value $.01 per share, of CTI ("CTI Common Stock"), each share of
preferred stock, Series A, no par value per share, of CTI (the "CTI Series A
Preferred Stock") and each share of preferred stock, Series B, no par value per
share, of CTI (the "CTI Series B Preferred Stock") (the CTI Series A Preferred
Stock and the CTI Series B Preferred Stock are collectively referred to herein
as the "CTI Preferred Stock" and the CTI Preferred Stock and the CTI Common
Stock are collectively referred to herein as the "CTI Capital Stock") issued and
outstanding immediately prior to the Effective Time (as defined in Section 1.3)
will be converted into the right to receive the consideration set forth in
Section 1.7;

     WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code"), and the regulations
promulgated thereunder; and

     WHEREAS, simultaneously with the execution and delivery of this Agreement,
WAXS is entering into an agreement with each of Roger Abbott and Rosalind
Abbott, Atocha, L.P., Gold & Appel Transfer S.A. and Edward Soren (the
"Principal Stockholders") pursuant to which each Principal Stockholder will
agree to, among other things, vote in favor of the Merger and certain
restrictions on the transfer of the consideration received in the Merger.

                                       B-1
<PAGE>   344

     NOW, THEREFORE, in consideration of the mutual representations, warranties
and covenants contained herein, and upon and subject to the terms and the
conditions hereinafter set forth, the parties do hereby agree as follows:

                                   ARTICLE I

                                   THE MERGER

     1.1 The Merger.  Upon the terms and subject to the conditions set forth in
this Agreement, and in accordance with the Delaware General Corporation Law (the
"DGCL") and the California General Corporation Law (the "CGCL"), CTI shall be
merged with and into Merger Sub at the Effective Time (as defined below).
Following the Merger, the separate corporate existence of CTI shall cease and
Merger Sub shall continue as the surviving corporation (the "Surviving
Corporation").

     1.2 Closing.  Subject to the satisfaction or waiver of the conditions set
forth in Article VII, the closing of the Merger and the transactions
contemplated by this Agreement (the "Closing") will take place on the second
business day following the satisfaction or written waiver of such conditions,
unless another time or date is agreed to in writing by the parties hereto (the
date of the Closing being referred to herein as the "Closing Date"). The Closing
shall be held at the offices of Long Aldridge & Norman LLP, 303 Peachtree
Street, Suite 5300, Atlanta, Georgia 30303.

     1.3 Effective Time.  On the Closing Date the parties shall (i) file a
certificate of merger in such form as is required by, and executed in accordance
with, the relevant provisions of the DGCL (the "Delaware Certificate of Merger")
and an agreement of merger in such form as is required by, and executed in
accordance with, the relevant provisions of the CGCL (the "California Agreement
of Merger") and (ii) make all other filings or recordings required under the
DGCL and the CGCL in connection with the Merger. The Merger shall become
effective at such time as the Delaware Certificate of Merger and the California
Agreement of Merger are duly filed with the Delaware Secretary of State and the
California Secretary of State, respectively, or at such subsequent time as WAXS
and CTI shall agree and as shall be specified in the Delaware Certificate of
Merger and the California Agreement of Merger (the date and time the Merger
becomes effective being the "Effective Time").

     1.4 Effects of the Merger.  At and after the Effective Time, the Merger
will have the effects set forth in the DGCL and the CGCL. Without limiting the
generality of the foregoing, and subject thereto, at the Effective Time all the
property, rights, privileges, powers, licenses, authorizations and franchises of
Merger Sub and CTI shall be vested in the Surviving Corporation, and all debts,
liabilities and duties of Merger Sub and CTI shall become the debts, liabilities
and duties of the Surviving Corporation.

     1.5 Articles of Incorporation/Bylaws.  The articles of incorporation and
bylaws of Merger Sub, as in effect immediately prior to the Effective Time,
shall be the articles of incorporation and bylaws of the Surviving Corporation,
until thereafter changed or amended as provided therein or by applicable law.

     1.6 New Directors of WAXS.  Immediately following the Effective Time, WAXS
shall cause one (1) designee of CTI to be elected to the Board of Directors of
WAXS. Such CTI designee shall be Walt Anderson, or such other person designated
by Gold & Appel Transfer S.A. and reasonably acceptable to WAXS.

     1.7 Conversion of Securities.  At the Effective Time, by virtue of the
Merger and without any action on the part of WAXS, Merger Sub, CTI or the
holders of any of the following securities:

          (a) [Intentionally Omitted.]

          (b) Each share of CTI Capital Stock issued and outstanding and
     directly or indirectly owned or held by CTI or a Subsidiary (as defined in
     Section 3.1(b)) thereof at the Effective Time shall, by virtue of the
     Merger, cease to be outstanding and shall be canceled and retired and no
     capital stock of WAXS or other consideration shall be delivered in exchange
     therefor.

                                       B-2
<PAGE>   345

          (c) Subject to Sections 2.4, 2.5 and 2.14 hereof, each share of CTI
     Capital Stock issued and outstanding immediately prior to the Effective
     Time shall be converted into the right to receive 0.6583 (the "Exchange
     Ratio") shares of common stock, par value $.01 per share, of WAXS ("WAXS
     Common Stock"). All shares of CTI Capital Stock, as of the Effective Time,
     shall no longer be outstanding and shall automatically be canceled and
     retired and each holder of a certificate representing any such shares (a
     "Certificate") shall cease to have any rights with respect thereto, except
     as set forth in this Section 1.7(c), Section 2.4, Section 2.5 and/or
     Section 2.14 and as provided under applicable law. The shares of WAXS
     Common Stock issuable pursuant to Section 1.7(c) and, if applicable, the
     Contingent Shares issuable pursuant to Section 1.7(d), together with any
     cash in lieu of fractional shares paid pursuant to Section 2.4, shall be
     referred to herein collectively as the "Merger Consideration."

          (d) In the event that the average of the closing prices of WAXS Common
     Stock as reported on the National Market System of the Nasdaq Stock Market
     (the "Nasdaq") for the ten (10) trading-day period ending at the close of
     trading on the second (2nd) trading day preceding the Closing (the
     "Averaging Period") is less than $20.38, then in addition to the shares of
     WAXS Common Stock issued pursuant to Section 1.7(c), each CTI stockholder
     who receives shares of WAXS Common Stock pursuant to Section 1.7(c) shall
     be entitled to receive, subject to Section 2.5, the amount, if any (the
     "Contingent Amount"), by which the Target Price (as defined below) exceeds
     the greater of (X) the Current Market Price (as defined below) on the first
     anniversary of the Effective Time (the "Maturity Date") and (Y) the Floor
     Price (as defined below), multiplied by the number of shares of WAXS Common
     Stock issued to such holder pursuant to Section 1.7(c). The maximum number
     of Contingent Shares that may be issued to CTI stockholders pursuant to
     this Section 1.7(d) shall in all events be less than fifty percent (50%) of
     the sum of the shares of WAXS Common Stock issued pursuant to Section
     1.7(c) plus the number of Contingent Shares issued pursuant to this Section
     1.7(d). The Contingent Amount shall only be paid in shares of WAXS Common
     Stock (the "Contingent Shares"), which shares shall be valued for purposes
     hereof at the greater of the Current Market Price as of the Maturity Date
     and the Floor Price and rounded to the nearest whole share. Notwithstanding
     anything to the contrary contained in this Agreement, any and all rights
     in, or to receive, the Contingent Amount shall terminate and be of no
     further force or effect if, at any time on or prior to the Maturity Date,
     the Current Market Price is greater than the Target Price. The parties
     further acknowledge and agree that if any shares of WAXS Common Stock
     constituting part of the Escrow Fund (as defined in Section 2.5) are
     released to WAXS in accordance with the Escrow Agreement (as defined in
     Section 7.1(e)), then the right to receive the Contingent Amount with
     respect to such shares of WAXS Common Stock shall terminate and be of no
     further force or effect. Neither the right to receive the Contingent Shares
     nor any interest therein shall be transferable or assignable by a holder of
     CTI Capital Stock except by operation of law. The terms and conditions
     relating to the Contingent Shares have been negotiated by WAXS and CTI so
     as to satisfy, to the extent possible, the specific requirements of Section
     3.03 of the IRS Revenue Procedure 77-37, as it has been amplified and
     superseded, which established the circumstances under which the Internal
     Revenue Service (the "IRS") previously issued advance rulings on contingent
     stock arrangements in mergers intended to qualify as "reorganizations"
     under Section 368(a) of the Code. Solely for purposes of this Agreement's
     compliance with such Revenue Procedure, the maximum number of shares of
     WAXS Common Stock issuable pursuant to Sections 1.7(c) and 2.6(b), and as
     Contingent Shares pursuant to this Section 1.7(d) is 58,146,739 shares of
     WAXS Common Stock.

          For purposes hereof, (a) the "Target Price" means $20.38 per share of
     WAXS Common Stock; provided, however, that if the Nasdaq Composite Index
     (the "IXIC") at the close of trading on the Maturity Date is eighty-five
     percent (85%), or less, of the IXIC at the close of trading on the date of
     the Effective Time (the difference between one hundred percent (100%) and
     such percentage being referred to as the "Market Correction Percentage"),
     then the Target Price shall be reduced by a percentage equal to that
     portion of the Market Correction Percentage in excess of fifteen percent
     (15%); (b) the "Current Market Price" means, as of any date specified
     herein, the average of the daily closing trading prices of WAXS Common
     Stock, as reported on the Nasdaq, for the
                                       B-3
<PAGE>   346

     twenty (20) consecutive trading days (in which such shares are traded on
     the Nasdaq) ending at the close of trading on such date; (c) the "Floor
     Price" means $11.50 per share of WAXS Common Stock; and (d) references to
     the "close of trading" as of or on a particular date shall mean such date,
     or if such date is not a trading day or no shares of WAXS Common stock are
     traded on the Nasdaq on such date, the last trading day preceding such date
     on which shares of WAXS Common Stock were traded on the Nasdaq.

     1.8 CTI Stock Options.

          (a) At the Effective Time, by virtue of the Merger and without any
     further action on the part of CTI, WAXS, Merger Sub or the holder of any
     outstanding CTI Stock Option (as defined in Section 3.2), each CTI Stock
     Option will be automatically converted into (i) an option to purchase
     shares of WAXS Common Stock (a "WAXS Stock Option") in an amount equal to
     the number of shares of CTI Common Stock covered under such CTI Stock
     Option multiplied by the Exchange Ratio (rounded to the nearest whole
     number of shares of WAXS Common Stock) at a price per share of WAXS Common
     Stock equal to the per share option exercise price specified in the CTI
     Stock Option divided by the Exchange Ratio (rounded to the nearest whole
     cent) and (ii) if applicable, the right to acquire for no additional
     consideration such number of Contingent Shares as is equal to the number of
     Contingent Shares the holder of such CTI Stock Option would be entitled to
     receive pursuant to Section 1.7(d) if such CTI Stock Option had been
     exercised immediately prior to the Effective Time. Each WAXS Stock Option
     shall contain terms and provisions which are substantially similar to those
     terms, conditions and provisions governing the original CTI Stock Option,
     except that references to CTI in such CTI Stock Option will be deemed to
     refer to WAXS and the date of grant of the CTI Stock Option shall be deemed
     to be the date of grant of such WAXS Stock Option. At the Effective Time,
     for purposes of interpretation of such new WAXS Stock Option, (i) all
     references in any stock option plan of CTI (including, without limitation,
     CTI's 1996 and 1999 Stock Option/Stock Purchase Plans) shall be deemed to
     refer to WAXS; (ii) any stock option plan of CTI which governs the CTI
     Stock Option shall continue to govern the WAXS Stock Option substituted
     therefor; and (iii) WAXS shall, as soon as practicable after the Effective
     Time, issue to each holder of an outstanding CTI Stock Option such
     documentation as appropriately evidences the foregoing issued and
     substituted WAXS Stock Option by WAXS. It is the intention of the parties:
     (1) that, subject to applicable law, CTI Stock Options assumed by WAXS
     qualify, following the Effective Time, as incentive stock options, as
     defined in Section 422 of the Code, to the extent that CTI Stock Options
     qualified as incentive stock options prior to the Effective Time, (2) that
     each holder of a CTI Stock Option shall receive a new WAXS Stock Option
     which preserves (but does not increase) the excess of the fair market value
     of the shares subject to such CTI Stock Option immediately before the
     Effective Time over the aggregate option price of such shares immediately
     before the Effective Time, if any such excess then exists, (3) that the
     terms, conditions, restrictions and provisions of the WAXS Stock Option be
     substantially similar to the terms, conditions, restrictions and provisions
     of the applicable CTI Stock Option, including without limitation, the same
     vesting schedule (other than to the extent accelerated pursuant to the
     existing terms of such CTI Stock Option or plan under which such Stock
     Option was granted), and (4) any terms conditions, restrictions or
     provisions of a CTI Stock Option applicable to a number of shares rather
     than a percentage or fraction of shares should be appropriately adjusted
     based upon the Exchange Ratio.

          (b) With respect to each CTI Stock Option converted into a WAXS Stock
     Option pursuant to Section 1.8(a), and with respect to the shares of WAXS
     Common Stock and Contingent Shares, if any, in respect of such shares of
     WAXS Common Stock underlying such option, WAXS shall file and keep current
     all requisite registration statements, on Form S-8 or other appropriate
     form(s), and comply in all other material respects with applicable state
     and federal requirements for as long as such options remain outstanding.

          (c) After the date of this Agreement, CTI agrees that it will not (x)
     grant any options, warrants or other rights to acquire any shares of CTI
     Capital Stock (except as set forth on SCHEDULE 5.1(C)),
                                       B-4
<PAGE>   347

     including any restricted stock, stock appreciation rights, limited stock
     appreciation rights or any other stock rights, (y) permit cash payments to
     holders of CTI Stock Options in lieu of the substitution therefor of WAXS
     Stock Options, as described in this Section 1.8 or (z) modify the vesting
     rules under any CTI Stock Option outstanding on the date hereof or take any
     other action (other than the transactions contemplated in this Agreement)
     which in any way would have the effect of accelerating the vesting of the
     options granted thereunder.

          (d) A holder of a WAXS Stock Option into which a CTI Stock Option has
     been converted in accordance with this Section 1.8 may exercise such option
     in whole or in part in accordance with its terms by delivering a properly
     executed notice of exercise to WAXS, together with the consideration
     therefor and the federal withholding tax information, if any, required in
     accordance with the related stock option plan.

     1.9 Certain Adjustments.  If between the date hereof and the Effective
Time, the outstanding WAXS Common Stock or CTI Capital Stock shall have been
changed into a different number of shares or different class by reason of any
reclassification, recapitalization, stock split, split-up, combination or
exchange of shares or a stock dividend or dividend payable in any other
securities shall be declared with a record date within such period, or any
similar event shall have occurred, the Exchange Ratio shall be appropriately
adjusted to provide to the holders of CTI Capital Stock and CTI Stock Options
the same economic effect as contemplated by this Agreement prior to such event.

                                   ARTICLE II


                            EXCHANGE OF CERTIFICATES


     2.1 Exchange Fund.  Prior to the Effective Time, WAXS shall appoint a
commercial bank or trust company reasonably acceptable to CTI to act as exchange
agent hereunder (the "Exchange Agent") for the purpose of exchanging
Certificates for the Merger Consideration. At or prior to the Effective Time,
WAXS shall deposit with the Exchange Agent, in trust for the benefit of holders
of shares of CTI Capital Stock, certificates representing the WAXS Common Stock
issuable pursuant to Section 1.7 in exchange for outstanding shares of CTI
Capital Stock. WAXS 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 2.4 and any dividends and other distributions pursuant to
Section 2.3. Any cash, certificates of WAXS Common Stock deposited with the
Exchange Agent shall hereinafter be referred to as the "Exchange Fund".

     2.2 Exchange Procedures.  As soon as reasonably practicable after the
Effective Time, the Surviving Corporation shall cause the Exchange Agent to mail
to each holder of a Certificate (i) a letter of transmittal which shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon delivery of the Certificates to the Exchange Agent, and
which letter shall be in customary form and have such other provisions as WAXS
may reasonably specify and (ii) instructions for effecting the surrender of such
Certificates in exchange for the applicable Merger Consideration. Upon surrender
of a Certificate to the Exchange Agent together with such letter of transmittal,
duly executed and completed in accordance with the instructions thereto, and
such other documents as may reasonably be required by the Exchange Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor (A)
one or more shares of WAXS Common Stock (which shall be in uncertificated book
entry form unless a physical certificate is requested) representing, in the
aggregate, the whole number of shares that such holder has the right to receive
pursuant to Section 1.7 (after taking into account all shares of CTI Capital
Stock then held by such holder), and (B) a check in the amount equal to the cash
that such holder has the right to receive pursuant to this Article II, including
cash in lieu of any additional shares of WAXS Common Stock pursuant to Section
2.4 and dividends and other distributions pursuant to Section 2.3. No interest
will be paid or will accrue on any cash payable pursuant to Section 2.3 or
Section 2.4. In the event of transfer of ownership of CTI Capital Stock which is
not registered in the transfer records of CTI, one or more certificates
evidencing, in the aggregate, the proper number of shares of WAXS Common Stock,
a check in the proper amount of cash in lieu of any additional shares of
                                       B-5
<PAGE>   348

WAXS Common Stock pursuant to Section 2.4, and any dividends or other
distributions to which such holder is entitled pursuant to Section 2.3, may be
issued with respect to such CTI Capital Stock to such a transferee if the
Certificate representing such shares of CTI Capital Stock is presented to the
Exchange Agent, accompanied by all documents required to evidence and effect
such transfer and to evidence that any applicable stock transfer taxes have been
paid.

     2.3 Distributions with Respect to Unexchanged Shares.  No dividends or
other distributions declared or made with respect to shares of WAXS Common Stock
with a record date after the Effective Time shall be paid to the holder of any
unsurrendered Certificate with respect to the shares of WAXS Common Stock that
such holder would be entitled to receive upon surrender of such Certificate and
no cash payment in lieu of fractional shares of WAXS Common Stock shall be paid
to any such holder pursuant to Section 2.4 until such holder shall surrender
such Certificate in accordance with Section 2.2. Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
paid to such holder of shares of WAXS Common Stock issuable in exchange
therefor, without interest, (a) promptly after the time of such surrender, the
amount of any cash payable in lieu of fractional shares of WAXS Common Stock to
which such holder is entitled pursuant to Section 2.4 and the amount of
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of WAXS Common Stock, and (b)
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 a
payment date subsequent to such surrender payable with respect to such shares of
WAXS Common Stock.

     2.4 No Fractional Shares of WAXS Common Stock.

          (a) No certificates or scrip or shares of WAXS Common Stock
     representing fractional shares of WAXS Common Stock or book-entry credit of
     the same shall be issued upon the surrender for exchange of Certificates,
     and such fractional share interests will not entitle the owner thereof to
     vote or to have any rights of a stockholder of WAXS.

          (b) Except for Contingent Shares, if any, notwithstanding any other
     provision of this Agreement, each holder of a Certificate exchanged for
     Merger Consideration who would otherwise have been entitled to receive a
     fraction of a share of WAXS Common Stock (after taking into account all
     Certificates delivered by such holder) shall receive, in lieu thereof, cash
     (without interest) in an amount equal to the product of (i) such fractional
     part of a share of WAXS Common Stock multiplied by (ii) the average closing
     price of WAXS Common Stock on the Nasdaq over the Averaging Period. As
     promptly as practicable after the determination of the amount of cash, if
     any, to be paid to holders of fractional interests, the Exchange Agent
     shall so notify WAXS, and WAXS shall cause the Surviving Corporation to
     deposit such amount with the Exchange Agent and shall cause the Exchange
     Agent to forward payments to such holders of fractional interests subject
     to and in accordance with the terms hereof.

     2.5 Escrow of Shares.

          (a) At the Closing, 2,453,385 of the shares of WAXS Common Stock to be
     issued to CTI's stockholders pursuant to Section 1.7(c) (collectively, the
     "Escrow Fund") shall be delivered to SunTrust Bank, Atlanta (the "Escrow
     Agent"), which Escrow Fund shall serve as the sole and exclusive source of
     recovery for any WAXS Protected Party (as defined in Section 8.1) for any
     indemnification claims hereunder. The Escrow Fund shall be held in escrow
     and released pursuant to the terms and conditions of the Escrow Agreement
     (as defined in Section 7.1(e)). The terms and conditions of the Escrow
     Agreement have been structured by WAXS and CTI so as to satisfy the
     specific requirements of Section 3.06 of IRS Revenue Procedure 77-37, as it
     has been amplified and superseded, which established the circumstances
     under which the IRS previously issued advance rulings on the escrow of
     stock in mergers intended to qualify as "reorganizations" under Section
     368(a) of the Code.

          (b) If any Contingent Shares are issued at a time that shares of WAXS
     Common Stock remain in escrow pursuant to the Escrow Agreement (as defined
     in Section 7.1(d)), then any Contingent
                                       B-6
<PAGE>   349

     Shares that are issued with respect to such shares of WAXS Common Stock
     shall be delivered to the Escrow Agent and shall be held and released in
     accordance with the terms and conditions of Section 4 of the Escrow
     Agreement.

     2.6 No Further Ownership Rights in CTI Capital Stock.

          (a) All shares of WAXS Common Stock issued and cash paid upon
     conversion of shares of CTI Capital Stock in accordance with the terms of
     this Article II (including any cash paid pursuant to Section 2.4) shall be
     deemed to have been issued or paid in full satisfaction of all rights
     pertaining to the shares of CTI Capital Stock.

          (b) Any accrued and unpaid dividends owed upon consummation of the
     Merger to any holder of CTI Preferred Stock in connection with the
     automatic conversion of such CTI Preferred Stock under the articles of
     incorporation of CTI shall be paid, at the Closing, solely in shares of
     WAXS Common Stock (valued at $20.38 per share). Any such shares so issued
     to any holder of CTI Preferred Stock shall not affect the Exchange Ratio.

     2.7 Termination of Exchange Fund.  Any portion of the Exchange Fund which
remains undistributed to the holders of Certificates for six months after the
Effective Time shall be delivered to the Surviving Corporation or otherwise on
the instruction of the Surviving Corporation, and any holders of the
Certificates who have not theretofore complied with this Article II shall
thereafter look only to the Surviving Corporation and WAXS for the Merger
Consideration with respect to the shares of CTI Capital Stock formerly
represented thereby to which such holders are entitled pursuant to Section 1.7
and Section 2.2, any cash in lieu of fractional shares of WAXS Common Stock to
which such holders are entitled pursuant to Section 2.4 and any dividends or
distributions with respect to shares of WAXS Common Stock to which such holders
are entitled pursuant to Section 2.3. Any such portion of the Exchange Fund
remaining unclaimed by holders of shares of CTI Capital Stock five years after
the Effective Time (or such earlier date immediately prior to such time as such
amounts would otherwise escheat to or become property of any Governmental Entity
(as defined in Section 3.6) shall, to the extent permitted by law, become the
property of the Surviving Corporation free and clear of any claims or interest
of any person previously entitled thereto.

     2.8 No Liability.  None of WAXS, Merger Sub, CTI, the Surviving Corporation
or the Exchange Agent shall be liable to any person in respect of any Merger
Consideration from the Exchange Fund delivered to a public official pursuant to
any applicable abandoned property, escheat or similar law.

     2.9 Investment of the Exchange Fund.  The Exchange Agent shall invest any
cash included in the Exchange Fund as directed by the Surviving Corporation on a
daily basis. Any interest and other income resulting from such investments shall
promptly be paid to the Surviving Corporation.

     2.10 Lost Certificates.  If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by the
Surviving Corporation, the posting by such person of a bond in such reasonable
amount as the Surviving Corporation may direct as indemnity against any claim
that may be made against it with respect to such Certificate, the Exchange Agent
will deliver in exchange for such lost stolen or destroyed Certificate the
applicable Merger Consideration with respect to the shares of CTI Capital Stock
formerly represented thereby, any cash in lieu of fractional shares of WAXS
Common Stock, and unpaid dividends and distributions on shares of WAXS Common
Stock deliverable in respect thereof, pursuant to this Agreement.

     2.11 Withholding Rights.  Each of the Surviving Corporation and WAXS shall
be entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any holder of shares of CTI Capital Stock such
amounts as it is required to deduct and withhold with respect to the making of
such payment under the Code and the rules and regulations promulgated
thereunder, or any provision of state, local or foreign tax law. To the extent
that amounts are so withheld by the Surviving Corporation or WAXS, as the case
may be, such withheld amounts shall be treated for all purposes of this
Agreement as
                                       B-7
<PAGE>   350

having been paid to the holder of the shares of CTI Capital Stock in respect of
which such deduction and withholding was made by the Surviving Corporation or
WAXS, as the case may be.

     2.12 Further Assurances.  At and after the Effective Time, the officers and
directors of the Surviving Corporation will be authorized to execute and
deliver, in the name and on behalf of CTI or Merger Sub, any deeds, bills of
sale, assignments or assurances and to take and do, in the name and on behalf of
CTI or Merger Sub, any other actions and things to vest, perfect or confirm of
record or otherwise in the Surviving Corporation any and all right, title and
interest in, to and under any of the rights, properties or assets acquired or to
be acquired by the Surviving Corporation as a result of, or in connection with,
the Merger.

     2.13 Stock Transfer Books.  The stock transfer books of CTI shall be closed
immediately upon the Effective Time and there shall be no further registration
of transfers of shares of CTI Capital Stock thereafter on the records of CTI. On
or after the Effective Time, any Certificates presented to the Exchange Agent or
WAXS for any reason shall be converted into the Merger Consideration with
respect to the shares of CTI Capital Stock formerly represented thereby, any
cash in lieu of fractional shares of WAXS Common Stock to which the holders
thereof are entitled pursuant to Section 2.4 and any dividends or other
distributions to which the holders thereof are entitled pursuant to Section 2.3.

     2.14 Further Holdback.  At the Closing, separately from the shares of WAXS
Common Stock comprising the Escrow Fund (which shall be deposited with the
Escrow Agent pursuant to the Escrow Agreement), a total of 49,068 of the shares
of WAXS Common Stock to be issued to CTI's stockholders pursuant to Section
1.7(c) (the "Expense Fund") shall be deemed delivered to each CTI stockholder
and at the deemed direction of each such stockholder delivered to an escrow
agent to be designated in writing by CTI not less than five (5) days prior to
the Closing Date. Any and all escrow provisions with respect to the Expense Fund
shall in all aspects satisfy the specific requirements of Section 3.06 of IRS
Revenue Procedure 77-37, as it has been amplified and superseded by the IRS. The
CTI stockholders as of immediately prior to the Effective Time shall be the
holders of record with full voting rights to all of the shares of WAXS Common
Stock held in the Expense Fund. The CTI stockholders as of immediately prior to
the Effective Time shall be entitled to exercise such voting rights until such
time, if any, as such shares of WAXS Common Stock are sold to pay
Representative's Costs pursuant to this Section 2.14. The escrow agent shall
deliver to the CTI stockholders as of immediately prior to the Effective Time
such proxies or other documents as may be necessary to enable such CTI
stockholders to exercise such voting rights. Further, the CTI stockholders as of
immediately prior to the Effective Time shall be entitled to promptly receive
any dividend distribution with respect to the shares of WAXS Common Stock held
in the Expense Fund. Any such dividends paid with respect to such shares shall
be distributed by the escrow agent to the CTI stockholders as of immediately
prior to the Effective Time as holders of record of such shares. The Expense
Fund shall be available in the good faith discretion of the Shareholder
Representative to pay the costs and expenses, if any, incurred by the
Shareholder Representative in defending (including, without limitation, assuming
the defense of any third party claims pursuant to Section 8.5) or otherwise
responding to, on behalf of the stockholders of CTI, any claims for
indemnification by any WAXS Protected Party pursuant to Article VIII hereof, or
otherwise in the performance of its duties hereunder, including, without
limitation, the reasonable fees, costs and expenses of attorneys, accountants
and other professionals engaged by the Shareholder Representative for such
purpose (collectively, the "Representative Costs"). The Shareholder
Representative shall have the authority to direct the sale from time to time of
such number of shares from the Expense Fund as may be necessary to reimburse the
Shareholder Representative for any Representative's Costs, which shall be
reimbursed to the Shareholder Representative from the Expense Fund promptly
after the escrow agent's receipt of a request therefor. The Shareholder
Representative shall also be entitled to have any Representative's Costs
advanced to the Shareholder Representative from the Expense Fund upon request
therefor, provided that any such advanced amounts not actually expended by the
Shareholder Representative to pay Representative's Costs shall be promptly
returned to the Expense Fund or returned to the stockholders of CTI as of
immediately prior to the Effective Time on a pro rata basis. All shares of WAXS
Common Stock or any cash amounts returned to the Expense Fund pursuant to the
immediately preceding sentence which are remaining in the
                                       B-8
<PAGE>   351

Expense Fund at the later to occur of (i) the expiration of the period for
asserting claims pursuant to Section 8.2(b) or (ii) the first date on which
there are no pending claims from any WAXS Protected Party shall be distributed
by the escrow agent to the stockholders of CTI as of immediately prior to the
Effective Time on a pro rata basis. CTI shall have authority to negotiate, and
the Shareholder Representative shall have authority to enter into an agreement
with the escrow agent designated by CTI, which shall effectuate the foregoing.
WAXS agrees that, notwithstanding any contrary provision of this Agreement, any
voting agreement between WAXS and any Principal Stockholder or any other
agreement entered into in connection herewith or therewith, any shares of WAXS
Common Stock comprising the Expense Fund may be sold from time to time at the
discretion of the Shareholder Representative as contemplated hereby. The
provisions of Section 8.7 shall apply to all actions taken by the Shareholder
Representative as contemplated hereunder.

                                  ARTICLE III


                     REPRESENTATIONS AND WARRANTIES OF CTI


     CTI hereby represents and warrants to WAXS as follows:

     3.1 Organization and Authorization.

          (a) Each of CTI and its Subsidiaries is a corporation duly organized,
     validly existing and in good standing under the laws of the jurisdiction of
     its incorporation or organization, as applicable, and has the corporate
     power and authority to carry on and conduct its business as it is now being
     conducted and to own or lease its properties and assets, and is duly
     qualified and in good standing. Each of CTI and its Subsidiaries is duly
     qualified and in good standing in every state of the United States and in
     such other jurisdictions (within or outside of the United States) in which
     the conduct of its business or the ownership of its properties and assets
     requires it to be so qualified except where the failure to be so qualified
     would not have a Material Adverse Effect (as defined in Section 3.6) on
     CTI.

          (b) SCHEDULE 3.1(B) sets forth (i) every entity in which CTI owns
     fifty percent (50%) or more of the outstanding equity, directly or
     indirectly (each a "Subsidiary" and collectively, the "Subsidiaries"), and
     (ii) the equity interest in such entity that is owned by CTI. Except as
     noted on SCHEDULE 3.1(B), all outstanding shares of capital stock of the
     Subsidiaries (the "Subsidiary Shares") are owned by CTI, directly or
     indirectly, free and clear of all liens, restrictions, claims, equities,
     charges, options, rights of first refusal or encumbrances. Except as set
     forth on SCHEDULE 3.1(B), CTI has full power, right and authority to vote
     all of the shares of capital stock of each Subsidiary which are owned or
     held by CTI. Except as set forth on SCHEDULE 3.1(B), CTI is not a party to
     or bound by any agreement prohibiting or restricting its right to transfer
     or vote the shares of capital stock of any Subsidiary which are owned or
     held by CTI.

          (c) Subject to the approval of this Agreement, the Merger and the
     other transactions contemplated hereby by the stockholders of CTI by the
     Required CTI Stockholder Vote, CTI has the corporate power to execute,
     deliver and perform this Agreement and to consummate the transactions and
     perform its obligations contemplated hereby. The execution, delivery and
     performance of this Agreement, and the consummation of the transactions
     contemplated hereby, have been duly and validly authorized by all necessary
     action on the part of CTI, subject to the approval of this Agreement, the
     Merger and the other transactions contemplated hereby by the stockholders
     of CTI by the Required CTI Stockholder Vote. This Agreement has been duly
     and validly executed and delivered by CTI and constitutes CTI's legal,
     valid and binding obligation, enforceable in accordance with its terms,
     except to the extent such enforcement may be limited by applicable
     bankruptcy, reorganization, moratorium or other such laws affecting the
     enforcement of creditors' rights generally.

     3.2 Authorized and Outstanding Stock.  The authorized capital stock of CTI,
the number of issued and outstanding shares thereof and the record holders of
such issued and outstanding shares of CTI's capital stock are set forth on
SCHEDULE 3.2. All of such issued and outstanding shares of capital stock of CTI
are validly issued, fully paid and nonassessable. There are outstanding options,
warrants or other
                                       B-9
<PAGE>   352

rights, to acquire an aggregate of 4,029,110 shares of capital stock of CTI
(each, a "CTI Stock Option"). SCHEDULE 3.2 lists the exercise price and vesting
schedule for each CTI Stock Option.

     3.3 Absence of Other Claims.  Except as set forth on SCHEDULE 3.2, there is
not outstanding, nor is CTI bound by, any subscriptions, options, preemptive
rights, warrants, calls, commitments or agreements or rights of any character
requiring CTI to issue or entitling any person or entity to acquire any
additional shares of capital stock or any other equity security of CTI,
including any right of conversion or exchange under any outstanding security or
other instrument, and CTI is not obligated to issue or transfer any shares of
its capital stock for any purpose. There are no outstanding obligations of CTI
to repurchase, redeem or otherwise acquire any outstanding shares of capital
stock of CTI.

     3.4 Financial Statements.  SCHEDULE 3.4 contains true, correct and complete
copies of (i) the audited consolidated balance sheet of CTI as of September 30,
1998, and the related audited statement of income, retained earnings, and cash
flows for the year then ended, and the related notes thereto; (ii) the audited
consolidated balance sheet of CTI as of September 30, 1999, and the related
audited statement of income, retained earnings, and cash flows for the year then
ended, and the related notes thereto; and (iii) the unaudited consolidated
balance sheet of CTI for the three (3) month period ending December 31, 1999,
and the related unaudited statement of income, retained earnings, and cash flows
for the period then ended (the "Interim Financial Statements") (collectively,
the "Financial Statements"). The Financial Statements present fairly, in all
material respects, the consolidated financial position of CTI, as of the dates
thereof, and the related results of its operations for the periods then ended.
Except as set forth on SCHEDULE 3.4, the Financial Statements have been prepared
in accordance with GAAP on a basis consistent with prior periods subject, in the
case of the Interim Financial Statements, to the absence of any notes thereto
and to normal and recurring year-end adjustments, which adjustments will not,
individually or in the aggregate, be material in amount.

     3.5 No Undisclosed Liabilities.  Except (i) as and to the extent reflected
and adequately reserved against in the Financial Statements, (ii) for
liabilities and obligations of a type not required under GAAP to be disclosed in
the Financial Statements and which were incurred in the ordinary course of
business, consistent with past practice or (iii) as shown on SCHEDULE 3.5, as of
September 30, 1999, CTI had no liabilities or obligations whatsoever, whether
accrued, absolute, contingent or otherwise. Since September 30, 1999, CTI has
not incurred any liability or obligation whatsoever, except for (i) liabilities
and obligations incurred in the ordinary course of business consistent with past
practice or (ii) as reflected on SCHEDULE 3.5.

     3.6 No Violation of Law.  Except as set forth on SCHEDULE 3.6, neither CTI
nor any of its Subsidiaries is or has been (by virtue of any past or present
action, omission to act, contract to which it is a party or any occurrence or
state of facts whatsoever) in violation of, or has received any notices of
violation with respect to, any applicable local, state, federal or international
law, ordinance, regulation, order, injunction or decree, or any other
requirement of any supranational, national, state, municipal, local or foreign
government, instrumentality, subdivision, court, administrative agency,
commission or authority thereof, or any quasi-governmental or private body
exercising any supranational, national, state, municipal, local or foreign
regulatory, taxing, importing or other governmental or quasi-governmental
authority (a "Governmental Entity") binding on it, or relating to its assets or
business, except where such violation or loss, liability, penalty or expense by
virtue thereof would not have a Material Adverse Effect on CTI. For purposes of
this Agreement, "Material Adverse Effect" means, with respect to any specified
entity, any change, circumstance or effect or breach of any of the provisions of
this Agreement that, individually or in the aggregate with all other changes,
circumstances and effects or breaches, is or would reasonably be expected to be
materially adverse to (i) the business, financial condition or results of
operations of such entity and its Subsidiaries taken as a whole, or (ii) the
ability of such entity (or the party owning such entity) to consummate the
transactions contemplated by this Agreement.

     3.7 Property.  Except where it would not have a Material Adverse Effect on
CTI:

          (a) Each of CTI and its Subsidiaries (i) has marketable fee simple
     title to all of its material real property and has valid title to all
     personal and mixed, tangible and intangible properties and
                                      B-10
<PAGE>   353

     assets which it purports to own, including all such real and personal
     properties and assets reflected, but not shown as leased or encumbered, in
     the Financial Statements (except for inventory and assets sold in the
     ordinary course of business consistent with past practice and supplies
     consumed in the ordinary course of business consistent with past practice);
     and (ii) except for Permitted Liens (as defined hereafter), owns such real
     and personal property free and clear of objections, liens, restrictions,
     claims, charges, security interests, easements or other encumbrances of any
     nature whatsoever, including any mortgages, leases, chattel mortgages,
     conditional sales contracts, collateral security arrangements and other
     title or interest retention arrangements. "Permitted Liens" shall mean (x)
     the security interests, easements or other encumbrances described in
     SCHEDULE 3.7 and (y) liens for Taxes not yet due and payable. All
     properties and assets of CTI and its Subsidiaries are in the possession or
     control of CTI or its Subsidiaries, as applicable.

          (b) Except as would not have a Material Adverse Effect on CTI, the
     plants, structures and equipment owned or leased by CTI or any of its
     Subsidiaries are structurally sound with no known defects, are in good and
     safe operating condition and repair and are adequate for the uses to which
     they are being put.

          (c) Except as would not have a Material Adverse Effect on CTI, the
     rights, properties and other assets presently owned, leased or licensed by
     CTI or any of its Subsidiaries include all rights, properties and other
     assets necessary to permit CTI and its Subsidiaries to conduct their
     business in the same manner as their business has been conducted in prior
     periods, without any need for replacement, refurbishment or extraordinary
     repair.

     3.8 [Intentionally Omitted.]

     3.9 [Intentionally Omitted.]

     3.10 Intellectual Property.

          (a) Generally.  SCHEDULE 3.10(A) sets forth a complete and accurate
     list of (i) all material patents, trademarks, service marks, trademark and
     service mark registrations, trademark and service mark registration
     applications, label filings, copyrights, inventions, patents and patent
     applications owned by CTI or any of its Subsidiaries and all agreements
     with respect thereto, (ii) all material trade names owned by CTI or any of
     its Subsidiaries and (iii) all contracts, agreements or understandings
     pursuant to which CTI or any of its Subsidiaries has authorized any person
     to use or any person has the right to use, in any business or commercial
     activity, any of the items listed in clauses (i) and (ii) above that are
     owned by CTI or any of its Subsidiaries. Except as would not have a
     Material Adverse Effect on CTI or as set forth on SCHEDULE 3.10(A), neither
     CTI nor any of its Subsidiaries has heretofore infringed upon, and is not
     now infringing upon, any patent, service mark, trade name, trademark,
     copyright, trade secret, or other intellectual property belonging to any
     other person. Except as would not have a Material Adverse Effect on CTI or
     as set forth on SCHEDULE 3.10(A), CTI does not know of any person
     infringing upon any of CTI's or its Subsidiaries' patents, service marks,
     trademarks, copyrights, trade secrets, or other intellectual property. CTI
     has made available to Buyer true, correct and complete copies of each
     trademark and service mark registration or application therefor, patent or
     patent application or other item listed in SCHEDULE 3.10(A) and each
     assignment or license with respect to any thereof.

          (b) Computer Software and Databases.  SCHEDULE 3.10(B) accurately
     identifies all material proprietary computer software and databases
     internally developed or acquired by CTI or any of its Subsidiaries
     (excluding generally available "shrink wrap" software and databases).
     Except as would not have a Material Adverse Effect on CTI, CTI and its
     Subsidiaries have all computer software and databases that are necessary to
     conduct the business of CTI and its Subsidiaries as presently conducted and
     all documentation relating to all such computer software and databases.
     Except as would not have a Material Adverse Effect on CTI, all such
     computer software and databases perform in accordance with the
     documentation related thereto or used in connection therewith and are free
     of defects in programming and operation. SCHEDULE 3.10(B) identifies each
     person to whom CTI or any
                                      B-11
<PAGE>   354

     of its Subsidiaries, in the last two (2) years, has sold, licensed, leased
     or otherwise transferred or granted any interest or rights to any of the
     computer software and databases described above and the date of each such
     sale, license, lease or other transfer or grant. CTI has made available to
     WAXS true, correct and complete copies of all documents relating to each
     such sale, license, lease or other transfer or grant.

          (c) Year 2000 Compliance.  Except as would not have a Material Adverse
     Effect on CTI, all computer hardware and software (including all computer
     hardware and software contained in imbedded systems) used in the business
     of CTI and its Subsidiaries or included in products previously or currently
     manufactured by CTI or any of its Subsidiaries (whether such hardware and
     software is owned by CTI or any of its Subsidiaries or is licensed from
     third parties) (collectively, the "Technology Systems") is designed to be
     used during and after the calendar year 2000 and such hardware and software
     will continue to operate during each such time period to accurately process
     date data (including, but not limited to calculating, comparing and
     sequencing) from, into and between the twentieth and twenty-first
     centuries, including leap year calculations ("Year 2000 Compliance").
     Except as would not have a Material Adverse Effect on CTI, the occurrence
     of the calendar year 2000 will not adversely affect the Technology Systems
     of CTI or any of its Subsidiaries or of third parties using products
     manufactured, or services provided, by CTI or any of its Subsidiaries. No
     expenditures in excess of currently budgeted items are necessary to cause
     Technology Systems to operate properly during and after the calendar year
     2000. CTI and its Subsidiaries have taken reasonable steps to determine
     whether the failure of any third parties with which CTI or any of its
     Subsidiaries has a relationship to achieve Year 2000 Compliance could have
     a Material Adverse Effect on CTI. Except as would not have a Material
     Adverse Effect on CTI, all computer hardware and software embedded in
     products manufactured, or services provided, by CTI or any of its
     Subsidiaries, when used in combination with, or interfacing with computer
     hardware and software of any other person, shall accurately accept, release
     and exchange date data, and shall continue to function in the same manner
     as it performs today and shall not otherwise impair the accuracy or
     function ability of such person's computer hardware or software.

     3.12 Employment Matters and Benefit Plans.

          (a) SCHEDULE 3.12(A) sets forth a list of all material agreements,
     arrangements, commitments, and policies (1) which relate to employee
     benefits; (2) which pertain to present or former employees, officers,
     retirees, directors or independent contractors (or their beneficiaries,
     dependents or spouses) of CTI or any of its Subsidiaries; and (3) which are
     currently in effect or expected to be adopted, maintained by, sponsored by,
     or contributed to by CTI or any other employer (a "CTI Affiliate")
                                      B-12
<PAGE>   355

     which, under Section 414 of the Code, would constitute a single employer
     with CTI (collectively referred to as "CTI Employee Benefit Plans",
     including, but not limited to, all: (A) employee benefit plans as defined
     in Section 3(3) of ERISA; and (B) all other deferred compensation,
     incentive, profit-sharing, thrift, stock ownership, stock appreciation
     rights, bonus, stock option, stock purchase, vacation, or other benefit
     plans or arrangements.

          (b) CTI and all CTI Affiliates have complied with their respective
     substantive obligations with respect to all CTI Employee Benefit Plans
     (including, but not limited to, (1) filing or distributing all reports or
     notices required by ERISA or the Code and (2) complying with all
     requirements of Part 6 of Title I of ERISA and Code Section 4980B) and have
     maintained the CTI Employee Benefit Plans in compliance with all applicable
     laws and regulations (including, but not limited to, ERISA and the Code),
     except where the failure to comply with such obligations would not result
     in a Material Adverse Effect on CTI. Each CTI Employee Benefit Plan that is
     intended to qualify under Code Section 401(a) has received a favorable
     determination letter (or other ruling indicating its tax-qualified status)
     from the IRS which is current with respect to all plan provisions required
     under applicable law for which such a letter can be obtained under IRS
     procedures, and the IRS has not threatened or taken any action to revoke
     any favorable determination letter issued with respect to any such CTI
     Employee Benefit Plan. No statement, either oral or written, has been made
     or administrative action has been taken by CTI or any CTI Affiliate (or any
     agent of either) to any Person regarding any CTI Employee Benefit Plans
     that is not in accordance with the terms of that plan that would have a
     Material Adverse Effect on CTI.

          (c) CTI has made available to WAXS true, correct and complete copies
     of all of the current documents relating to the CTI Employee Benefit Plans,
     including, but not limited to (1) all plan texts (including any subsequent
     amendments), trust instruments and other funding arrangements adopted or
     entered into in connection with each of the CTI Employee Benefit Plans; (2)
     the notices and election forms used to notify employees and their
     dependents of their continuation coverage rights under group health plans
     (under Code Section 4980B(f) and ERISA Section 606), if applicable; and (3)
     the most recent Form 5500 annual reports (including all schedules thereto),
     summary plan descriptions and favorable determination letters, if
     applicable, for Employee Benefit Plans. Since the date such documents were
     supplied to WAXS, no plan amendments have been adopted and no such
     amendments or changes shall be adopted or made prior to the Closing Date
     without WAXS's approval, except as required by applicable law after the
     date hereof.

          (d) Except as listed in SCHEDULE 3.12(D), neither CTI nor any CTI
     Affiliate has any material agreement, arrangement, commitment or
     understanding to create any additional CTI Employee Benefit Plans or to
     continue, modify, change or terminate any existing CTI Employee Benefit
     Plans.

          (e) None of the CTI Employee Benefit Plans (1) is currently under
     investigation, audit or review by the U.S. Department of Labor, the IRS,
     the Pension Benefit Guaranty Corporation or any other federal or state
     agency or (2) is liable for any federal, state, local or foreign taxes that
     would have a Material Adverse Effect on CTI. Except for such liabilities
     that would not have a Material Adverse Effect on CTI, there is no
     transaction in connection with which CTI or any CTI Affiliate could be
     subject to either a civil penalty assessed pursuant to ERISA Section 502, a
     tax imposed by Code Section 4975 or liability for a breach of fiduciary
     responsibility under ERISA.

          (f) Other than routine claims for benefits payable to participants or
     beneficiaries in accordance with the terms of the CTI Employee Benefit
     Plans, or relating to qualified domestic relations orders (as defined in
     Section 414(p) of the Code), there are no claims, pending or threatened, by
     any participant or beneficiary against any of the CTI Employee Benefit
     Plans or any fiduciary of any of the CTI Employee Benefit Plans that would
     have a Material Adverse Effect on CTI.

          (g) Neither CTI nor any CTI Affiliate has at any time maintained,
     sponsored or contributed to any "pension plan", as defined in ERISA Section
     3(2), which is subject to Title IV of ERISA or contributed to any pension
     plan which is a "multiemployer plan" as defined in ERISA Section 3(37)(A).

          (h) SCHEDULE 3.12(H) sets forth a list of all agreements,
     arrangements, commitments and CTI Employee Benefit Plans, under which (1)
     any benefits will be increased, (2) the vesting or exercisability of
     benefits will be accelerated, (3) amounts will become immediately payable,
     and/or (4) the immediate funding for any benefits is required, upon the
     occurrence of the transactions contemplated by this Agreement. Except with
     respect to CTI Stock Options, SCHEDULE 3.12(H) also sets forth a good faith
     estimate of the total value and/or cost of any such change in control
     benefits and/or funding and a statement of the time periods in which such
     payments must be made and/or funding obligations must be met, including but
     not limited to the value and/or costs of any gross up payments for tax
     purposes.

          (i) To the knowledge of CTI, no key employee, or group of employees of
     CTI has any plans to terminate employment with CTI or any of its
     Subsidiaries other than employees with plans to retire. CTI and its
     Subsidiaries have complied with all laws relating to the employment of
     labor, including provisions thereof relating to wages, hours and equal
     opportunity, and it does not have any labor relations problems (including
     threatened or actual strikes or work stoppages or grievances), except for
     such failures or problems that would not have a Material Adverse Effect on
     CTI.

     3.13 Collective Bargaining.  Except as set forth on SCHEDULE 3.13, there
are no labor contracts, collective bargaining agreements, letters of
understanding or other arrangements, formal or informal, with any union or labor
organization covering any of CTI's or its Subsidiaries' employees and none of
said employees are represented by any union or labor organization. CTI has made
available to Buyer a true, correct, and complete copy of each agreement listed
on SCHEDULE 3.13.

     3.14 Labor Disputes.  CTI and its Subsidiaries are in compliance with all
federal and state laws respecting employment and employment practices, terms and
conditions of employment, wages and hours, except where the failure to be in
compliance would not have a Material Adverse Effect on CTI. No unfair labor
practice complaint against CTI or any of its Subsidiaries is pending before the
National Labor Relations Board. CTI does not know of any labor strike or other
labor trouble actually pending, being threatened against, or affecting CTI or
any of its Subsidiaries. Relations between management and labor are amicable and
there have not been, nor are there presently, any attempts to organize non-union
employees, nor are there plans for any such attempts.

     3.15 Investments.  Except for the Subsidiary Shares and as disclosed on
SCHEDULE 3.15, neither CTI nor any of its Subsidiaries owns any capital stock or
other securities or have any other material investment in any person or other
entity.

     3.16 Tax Matters.  Except as set forth on SCHEDULE 3.16:

          (a) (i) All material Tax Returns required to be filed under applicable
     law by CTI and each of its Subsidiaries have been filed, or requests for
     extensions have been timely filed and have not expired; (ii) all such Tax
     Returns filed by CTI and its Subsidiaries are complete and accurate in all
     material respects; (iii) all Taxes shown to be due on such Tax Returns or

     Financial Statements reflect that adequate reserves have been established
     for the payment of such Taxes, and no other material Taxes are payable by
     CTI and its Subsidiaries with respect to items or periods covered by such
     Tax Returns (whether or not shown on or reportable on such Tax Returns) or
     with respect to any period prior to the date of this Agreement; (iv) CTI
     and each of its Subsidiaries has disclosed on their federal income Tax
     Return all positions taken therein that could give rise to a substantial
     understatement of income Tax within the meaning of Section 6662 of the
     Code; (v) there are no material liens on any of the assets of CTI or any of
     its Subsidiaries with respect to Taxes, other than liens for Taxes not yet
     due and payable or for Taxes that CTI or any of its Subsidiaries is
     contesting in good faith through appropriate proceedings and for which the
     Financial Statements reflect that appropriate reserves have been
     established; (vi) no power of attorney to deal with Tax matters or waiver
     or extension of any statute of limitations with respect to Taxes has been
     granted by CTI or any of its Subsidiaries; and (vii) there is no (X) audit,
     examination, deficiency or refund litigation or matter in controversy with
     respect to any Taxes of CTI and its Subsidiaries nor (Y) has the IRS nor
     any other Tax authority asserted any claim for Taxes in
                                      B-14
<PAGE>   357

     writing, or to the knowledge of CTI, is threatening to assert any claim for
     Taxes, that might reasonably be expected to result in a Tax determination
     which would have a Material Adverse Effect on CTI.

          (b) SCHEDULE 3.16 sets forth the names of the Subsidiaries of CTI
     which are or have been a member of an affiliated group of corporations
     filing a consolidated federal income Tax Return (or a group of corporations
     filing a consolidated, combined or unitary income Tax Return under
     comparable provisions of state, local or foreign Tax law) other than a
     group the common parent of which was CTI;

          (c) There are no contracts, agreements, plans or arrangements,
     including but not limited to the provisions of this Agreement, covering any
     employee or former employee of CTI or any of its Subsidiaries that,
     individually or collectively, could give rise to the payment of any amount
     (or portion thereof) that would not be deductible pursuant to Section 280G
     of the Code.

          (d) Neither CTI nor any of its Subsidiaries is a party to (i) a Tax
     Sharing Agreement, (ii) transactions which have produced deferred
     intercompany gains, losses or other intercompany items or excess loss
     accounts (within the meaning of Treas. Reg. sec. 1.1502-13 or 1.1502-19,
     respectively, or any predecessor regulations or any comparable items for
     state, local or non-United States Tax purposes), or (iii) any joint
     venture, partnership, limited liability company or other arrangement or
     contract that should be treated as a partnership for federal income Tax
     purposes or as to which, an election has been made under Treas. Reg. sec.
     301.7701-3 to have the entity disregarded for federal income Tax purposes
     as an entity separate from its owner.

          (e) None of CTI and its Subsidiaries (i) has or has had operations or
     assets outside the United States taxable as a "branch" by the United States
     or as a "permanent establishment" by any foreign country, (ii) has received
     written notice of any claim made by a Tax authority in a jurisdiction where
     CTI or any of its Subsidiaries does not file Tax Returns that it is or may
     be subject to Taxes in such jurisdiction, (iii) is a "passive foreign
     investment company" within the meaning of the Code, (iv) has participated
     in or cooperated with an international boycott or has been requested to do
     so in connection with any prior transaction or the transactions
     contemplated by this Agreement, and (v) has availed itself of any Tax
     amnesty, Tax holiday or similar relief in any jurisdiction.

          (f) CTI has made available to WAXS true copies of (i) all material Tax
     Returns that CTI or its Subsidiaries have filed since its fiscal year ended
     September 30, 1995, and (ii) all material correspondence, including without
     limitation, closing agreements, private letter rulings, advance pricing
     agreements and gain recognition agreements and other written submissions to
     or communications with any Tax authorities.

          (g) (i) There is no plan or intention on the part of holders of CTI
     Capital Stock who own five percent (5%) or more of the CTI Capital Stock by
     vote or value (the "5% CTI stockholders"), nor have any of such 5% CTI
     stockholders entered any agreement, and to the knowledge of CTI, there is
     no plan or intention on the part of the remaining holders of CTI Capital
     Stock to sell, exchange or otherwise dispose of a number of shares of WAXS
     Common Stock received in the Merger (excluding the Contingent Shares, if
     any) to any person related to WAXS within the meaning of Treas. Reg. sec.
     1.368-1(e)(3) that would reduce the CTI stockholders' aggregate ownership
     of such WAXS Common Stock to a number of shares of WAXS Common Stock having
     a value, as of the Effective Time of the Merger, of less than fifty percent
     (50%) of the value of all of the formerly outstanding CTI Capital Stock as
     of the Effective Time. For purposes of this representation, shares of WAXS
     Common Stock exchanged for cash or other property, surrendered by
     dissenters or exchanged for cash in lieu of fractional shares of WAXS
     Common Stock will be treated as outstanding CTI Capital Stock as of the
     Effective Time. Any third party who may acquire WAXS Common Stock from
     Roger Abbott and Rosalind Abbott as former CTI stockholders after the
     Merger as contemplated in the Voting and Stock Transfer Restriction
     Agreement dated as of the date hereof between WAXS and Roger Abbott and
     Rosalind Abbott (the "Abbott Voting and Stock Transfer Restriction
     Agreement"), will not be a person related to WAXS within the meaning of
                                      B-15
<PAGE>   358

     Treas. Reg. sec. 1.368-1(e)(3), and there are no facts and circumstances
     indicating that the cash to be used by each such third party to purchase
     the WAXS Common Stock from such former CTI stockholders receiving WAXS
     Common Stock in the Merger will in substance be exchanged by WAXS or any of
     its Subsidiaries for CTI Capital Stock.

             (ii) The fair market value of the WAXS Common Stock (inclusive of
        Contingent Shares, if any) and cash in lieu of fractional shares of
        Parent Common Stock, if any, together with any cash paid or shares of
        WAXS Common Stock issued, as the case may be, in satisfaction of accrued
        unpaid dividends on CTI Preferred Stock, received by each holder of CTI
        Capital Stock in the Merger will be approximately equal to the fair
        market value of the shares of CTI Capital Stock surrendered in the
        Merger by each CTI stockholder.

             (iii) CTI is not a regulated investment company, a real estate
        investment trust, or a corporation fifty percent (50%) or more of the
        value of whose total assets (excluding cash, cash items, receivables and
        U.S. government securities) are stock or securities and eighty percent
        (80%) or more of the value of whose total assets are assets held for
        investment. For purposes of the fifty percent (50%) and eighty percent
        (80%) determinations under the preceding sentence, stock and securities
        in any subsidiary corporation shall be disregarded and the parent
        corporation shall be deemed to own its ratable share of the subsidiary's
        assets. A corporation shall be considered a subsidiary for purposes of
        this paragraph if the parent owns fifty percent (50%) or more of the
        combined voting power of all classes of stock entitled to vote, or fifty
        percent (50%) or more of the total value of shares of all classes of
        stock outstanding.

             (iv) In the Merger, CTI will transfer to Merger Sub at least ninety
        percent (90%) of the fair market value of its net assets, and at least
        seventy percent (70%) of the fair market value of its gross assets held
        immediately prior to the Merger. For purposes of this representation,
        amounts paid by CTI to dissenters or to CTI stockholders who receive
        cash or other property, CTI assets used by CTI to pay reorganization
        expenses, and CTI assets used for redemptions and distributions
        (excluding regular, normal dividends) made by CTI prior to the Effective
        Time will be included as assets of CTI held immediately prior to the
        Merger.

             (v) None of the compensation received by any stockholder-employee
        of CTI will be separate consideration for, or allocable to, any of the
        shares of CTI Capital Stock held by such stockholder-employee; none of
        the shares of WAXS Common Stock issued in the Merger and received by any
        stockholder-employee of CTI will be separate consideration for, or
        allocable to, any employment agreement, agreement not to compete or any
        other compensation owed or owing to such stockholder-employee; and the
        compensation paid to any stockholder-employee of CTI will be for
        services actually rendered and will be commensurate with amounts paid to
        third parties bargaining at arm's length for similar services.

             (vi) CTI and each of its stockholders will pay their respective
        expenses, if any, incurred in connection with the Merger.

             (vii) There is no intercorporate indebtedness existing between WAXS
        and CTI or between CTI and the Merger Sub that was issued, acquired, or
        will be settled at a discount.

             (viii) At the Effective Time of the Merger, the fair market value
        of the assets of CTI transferred to Merger Sub will equal or exceed the
        sum of its liabilities assumed by Merger Sub, plus (without duplication)
        the amount of liabilities, if any, to which the transferred assets of
        CTI are subject.

             (ix) The liabilities of CTI assumed by Merger Sub and the
        liabilities of CTI to which the transferred assets of CTI are subject
        were incurred by CTI in the ordinary course of its business.

             (x) CTI is not under the jurisdiction of a court in a Title 11 or
        similar case within the meaning of Section 368(a)(3)(A) of the Code.

                                      B-16
<PAGE>   359

             (xi) The business carried on by CTI at the Effective Time is its
        "historic business" within the meaning of Treas. Reg. sec. 1.368-1(d).

             (xii) Prior to the Effective Time, CTI has not distributed the
        stock of any corporation in a distribution qualifying for Tax-free
        treatment under Section 355 of the Code.

             (xiii) During the five (5) year period ending as of the Effective
        Time, neither CTI nor any persons related to CTI within the meaning of
        Treas. Reg. sec. 1.368-1(e)(3) (but without regard to Treas. Reg. sec.
        1.368-1(e)(3)(i)(A)) will have directly or through any transaction,
        agreement, or arrangement with any other person, (A) acquired CTI
        Capital Stock with consideration other than shares of WAXS capital stock
        or CTI Capital Stock or (B) made any "extraordinary distributions" with
        respect to CTI Capital Stock within the meaning of Treas. Reg. sec.
        1.368-1T(e)(1)(ii)(A).

             (xiv) The principal purposes of CTI for participating in the Merger
        are bona fide purposes unrelated to Taxes, and the terms of this
        Agreement are the product of arm's-length negotiations.

             (xv) CTI and each of its Subsidiaries are not currently, have not
        been within the last five (5) years, and do not anticipate becoming a
        "United States real property holding corporation" within the meaning of
        Section 897(c) of the Code.

             (xvi) There is a valid business reason underlying the Section
        1.7(d) provisions concerning the possible issuance of Contingent Shares
        and the provisions of this Agreement relating to Contingent Shares
        satisfy the specific requirements of Section 3.03 of IRS Revenue
        Procedure 77-37, as it has been amplified and superseded by the IRS.

             (xvii) There is a valid business reason for the escrow of shares of
        WAXS Common Stock, including Contingent Shares, if any, pursuant to
        Section 2.5 of this Agreement and the Escrow Agreement described in
        Section 7.1(d), and the escrow provisions of this Agreement and the
        Escrow Agreement satisfy the specific requirements of Section 3.06 of
        IRS Revenue Procedure 77-37, as it has been amplified and superseded by
        the IRS.

             (xviii) There is a valid business reason for the escrow of shares
        of WAXS Common Stock comprising the Expense Fund pursuant to Section
        2.14 of this Agreement, and the escrow provisions of Section 2.14
        satisfy the specific requirements of Section 3.06 of IRS Revenue
        Procedure 77-37, as it has been amplified and superseded by the IRS.

          (h) For purposes of this Agreement:

             (i) "Tax" (and, with correlative meaning, "Taxes" shall mean: (i)
        all taxes, charges, fees, levies or other assessments, however
        denominated, including any interest, penalties or other additions to tax
        that may become payable in respect thereof, imposed by any federal,
        territorial, state, local or foreign government or any agency or
        political subdivision of any such government, which taxes shall include,
        without limiting the generality of the foregoing, all income or profits

        income taxes), payroll and employee withholding taxes, unemployment
        insurance, social security taxes, sales and use taxes, ad valorem taxes,

        Benefit Guaranty Corporation premiums and other governmental charges,
        and other obligations of the same or of a similar nature to any of the
        foregoing, which the Person is required to pay, withhold or collect; and
        (ii) any liability for the payment of any amounts described in clause
        (i) as a result of being a successor to or transferee of any individual
        or entity or a member of an affiliated, consolidated or unitary group
        for any period (including pursuant to Treas. Reg. sec. 1.1502-6 or
        comparable provisions of state, local or foreign tax law); and (iii) any
        liability for the payment of amounts

it or any of its property or any of its capital stock is subject, except where
the failure to obtain such consent or approval would not have a Material Adverse
Effect on CTI.

     date of such filing) presents fairly, in all material respects, the
     consolidated financial position and consolidated results of operations and
     cash flows of WAXS and its Subsidiaries as of the respective dates or for
     the respective periods set forth therein all in conformity with GAAP

     statements, to normal and recurring year-end adjustments that have not been

     their respective dates (or as of the date of any amendment to the
     respective WAXS SEC Report filed prior to the date of this Agreement),
     complied as to form in all material respects with the applicable
     requirements of the Securities Act of 1933, as amended (the "Securities

     Act"), and the rules and regulations promulgated thereunder.

     since December 31, 1999, WAXS and its Subsidiaries have not incurred any
     liabilities that are of a nature that would be required to be disclosed on
     a balance sheet of WAXS and its Subsidiaries or the footnotes thereto

     the ordinary course of business or (B) liabilities that would not have a
     Material Adverse Effect on WAXS.

     4.7 Brokers and Advisers.  Except for Donaldson, Lufkin & Jenrette

Statement/Prospectus (as defined herein) will, on the date it is first mailed to
WAXS's stockholders, or at the time of the WAXS Stockholders Meeting contain any
untrue statement of a material fact or omit to state any 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. The Proxy
Statement/Prospectus will, on the date it is first mailed to WAXS's stockholders
and at the time of the WAXS Stockholders Meeting, comply as to form in all
material respects with the requirements of the Exchange Act and the rules and
regulations promulgated thereunder.

or effect relating (A) to the economy or financial markets in general, or (B) in

          (a) (i) All material Tax Returns required to be filed under applicable

     extensions have been timely filed and have not expired; (ii) all such Tax
     Returns filed by WAXS and its Subsidiaries are complete and accurate in all
     material respects; (iii) all Taxes shown to be due on such Tax Returns or
     on subsequent assessments with respect thereto have been paid or the WAXS
     SEC Reports reflect that adequate reserves have been established for the
     payment of such Taxes, and no other material Taxes are payable by WAXS or
     any of its Subsidiaries with respect to items or periods covered by such
     Tax Returns (whether or not shown on or reportable on such Tax Returns) or

     Reports reflect that appropriate reserves have been established; and (v)
     there is no audit, examination, deficiency or refund litigation or matter
     in controversy with respect to any Taxes of WAXS and its Subsidiaries that
     might reasonably be expected to result in a Tax determination which would
     have a Material Adverse Effect on WAXS.

          (b) There are no contracts, agreements, plans or arrangements,
     including but not limited to the provisions of this Agreement, covering any
     employee or former employee of WAXS or any of its Subsidiaries that,
     individually or collectively, could give rise to the payment of any amount
     (or portion thereof) that would not be deductible pursuant to Section 280G
     of the Code.

          (c) Neither WAXS nor any of its Subsidiaries is a party to a Tax
     Sharing Agreement.

          (d) (i) During the five (5) year period beginning as of the Effective
     Time, neither WAXS nor any person "related" to WAXS within the meaning of
     Treas. Reg. sec. 1.368-1(e)(3) will (A) be under any obligation and will
     have entered into any agreement to redeem or repurchase any of the WAXS
     Common Stock issued in the Merger or to make any "extraordinary
     distributions" within the meaning of Treas. Reg. sec. 1.368-1T(e)(1)(ii)(A)
     in respect of the WAXS Common Stock and (B) have a plan or intention to
     reacquire any of the WAXS Common Stock issued in the Merger either directly
     or through any transaction, agreement or arrangement with any other person,
     except (X) for escrowed shares of WAXS Common Stock, if any, which may be
     returned to WAXS pursuant to the Escrow Agreement and (Y) that WAXS may
     repurchase shares of WAXS Common Stock on the open market through a broker
     for the prevailing market price pursuant to an open-market repurchase
     program as described in Rev. Rul. 99-58, 1999-52 I.R.B. 701. To the
     knowledge of WAXS, any third party who may acquire WAXS Common Stock from
     Roger Abbott and Rosalind Abbott as former CTI stockholders after the
     Merger as contemplated by the Abbott Voting and Stock Transfer Restriction
     Agreement will not be a person related to WAXS within the meaning of Treas.
     Reg. sec. 1.368-1(e)(3) and to the knowledge of WAXS, there are no facts
     and circumstances indicating that the cash to be used by any such third
     party to purchase the WAXS Common Stock from such former CTI stockholders
     receiving such WAXS Common Stock in the Merger will in substance be
     exchanged by WAXS or any of its Subsidiaries for CTI Capital Stock.

             (ii) As of the Effective Time, neither WAXS nor any person related
        to WAXS within the meaning of Treas. Reg. sec. 1.368-1(e)(3) will own
        beneficially or of record, nor will have owned during the past five (5)
        years, any CTI Capital Stock or securities of CTI or options or
        instruments giving the holder thereof the right to acquire CTI Capital
        Stock or securities of CTI.

             (iii) Prior to or in the Merger, neither WAXS nor any person
        related to WAXS within the meaning of Treas. Reg. sec. 1.368-1(e)(3)
        will have acquired directly or through any transaction,

                                      B-25
<PAGE>   368

        agreement or arrangement with any other person, any capital stock of CTI
        with consideration other than shares of WAXS Common Stock.

             (iv) The fair market value of the WAXS Common Stock (inclusive of
        Contingent Shares, if any) and cash in lieu of fractional shares of WAXS
        Common Stock, if any, together with any cash paid or shares of WAXS
        Common Stock issued, as the case may be, in satisfaction of accrued
        unpaid dividends on CTI Preferred Stock, received by each holder of CTI
        Capital Stock in the Merger will be approximately equal to the fair
        market value of the shares of CTI Capital Stock surrendered in the
        Merger by each CTI stockholder.

             (v) Following the Merger, WAXS will cause Merger Sub to continue
        CTI's "historic business" within the meaning of Treas. Reg. sec.
        1.368-1(d) or use a significant portion of CTI's historic business
        assets in a business. For purposes of this representation, Merger Sub
        will be treated as conducting CTI's historic business or using a
        significant portion of CTI's historic business assets in a business if
        (a) the members of the WAXS "qualified group" (as defined below in this
        Section 4.15(d)(viii)), in the aggregate, continue the historic business
        of CTI or use a significant portion of CTI's historic business assets in
        a business, or (b) the foregoing activities are undertaken by a
        partnership in which (1) the members of the WAXS qualified group, in the
        aggregate, own at least a thirty-three and one third percent (33 1/3%)
        interest in the partnership, or (ii) one or more members of the
        qualified group has active and substantial management functions as a
        partner with respect to the partnership business and the members of the
        qualified group, in the aggregate, own at least a twenty percent (20%)
        interest in the partnership.

             (vi) On and prior to the Effective Time, WAXS will be in "control"
        of Merger Sub within the meaning of Section 368(c) of the Code, which is
        a newly-formed corporation that was organized for the sole purpose of
        facilitating the Merger.

             (vii) WAXS has no plan or intention, and WAXS has no plan or
        intention to cause the Merger Sub, to issue additional shares of its
        capital stock following the Merger, or take any other action, that would
        result in WAXS losing "control" of the Merger Sub within the meaning of
        Section 368(c) of the Code.

             (viii) WAXS has no plan or intention following the Merger to
        liquidate the Merger Sub; to merge the Merger Sub with and into another
        corporation; to sell or otherwise dispose of the stock of the Merger
        Sub; or to cause the Merger Sub to sell or otherwise dispose of any of
        the assets acquired from CTI, except for dispositions made in the
        ordinary course of business or for transfers or successive transfers of
        all or part of the assets acquired from CTI to a member(s) of the WAXS
        qualified group or to a partnership that has a member(s) of the
        qualified group as a partner who own, in the aggregate, at least a
        thirty-three and one third percent (33 1/3%) interest in the
        partnership, or (ii) one or more members of the qualified group has
        active and substantial management functions as a partner with respect to
        the partnership business and the members of the qualified group, in the
        aggregate, own at least a twenty percent (20%) interest in the
        partnership. For purposes of this Section 4.15(d) and as set forth under
        Treas. Reg. sec. 1.368-1(d)(4)(ii), the term "qualified group" shall
        mean one or more chains of corporations connected through stock
        ownership with WAXS, but only if WAXS owns directly stock meeting the
        requirements of Section 368(c) of the Code in at least one other
        corporation, and stock meeting the requirements of Section 368(c) of the
        Code in each of the corporations (except WAXS) is owned directly by one
        of the other corporations.

             (ix) WAXS and Merger Sub will pay their respective expenses, if
        any, incurred in connection with the Merger.

             (x) There is no intercorporate indebtedness existing between WAXS
        and CTI or between the Merger Sub and CTI that was issued, acquired, or
        will be settled at a discount.

                                      B-26
<PAGE>   369

             (xi) Neither WAXS nor Merger Sub is a regulated investment company,
        a real estate investment trust, or a corporation fifty percent (50%) or
        more of the value of whose total assets (excluding cash, cash items,
        receivables and U.S. government securities) are stock or securities and
        eighty percent (80%) or more of the value of whose total assets are
        assets held for investment. For purposes of the fifty percent (50%) and
        eighty percent (80%) determinations under the preceding sentence, stock
        and securities in any subsidiary corporation shall be disregarded and
        the parent corporation shall be deemed to own its ratable share of the
        subsidiary's assets. A corporation shall be considered a subsidiary for
        purposes of this paragraph if the parent owns fifty percent (50%) or
        more of the combined voting power of all classes of stock entitled to
        vote, or fifty percent (50%) or more of the total value of shares of all
        classes of stock outstanding.

             (xii) No stock of the Merger Sub will be issued in the Merger.

             (xiii) Neither WAXS nor the Merger Sub is under the jurisdiction of
        a court in a Title 11 or similar case within the meaning of Section
        368(a)(3)(A) of the Code.

             (xiv) In the Merger, to the knowledge of WAXS, the Merger Sub will
        acquire at least ninety percent (90%) of the fair market value of CTI's
        net assets, and at least seventy percent (70%) of the fair market value
        of CTI's gross assets held immediately prior to the Merger. For purposes
        of this representation, amounts paid by CTI to dissenters or to CTI
        stockholders who receive cash or other property, CTI assets used by CTI
        to pay reorganization expenses, and CTI assets used for redemptions and
        distributions (excluding regular, normal dividends) made by CTI prior to
        the Effective Time will be included as assets of CTI held immediately
        prior to the Merger.

             (xv) None of the compensation received by any stockholder-employee
        of CTI will be separate consideration for, or allocable to, any of the
        shares of CTI Capital Stock held by such stockholder-employee; none of
        the shares of WAXS Common Stock issued in the Merger and received by any
        stockholder-employee of CTI will be separate consideration for, or
        allocable to, any employment agreement, agreement not to compete or any
        other compensation owed or owing to such stockholder-employee; and the
        compensation paid to any stockholder-employee of CTI will be for
        services actually rendered and will be commensurate with amounts paid to
        third parties bargaining at arm's length for similar services.

             (xvi) The payment of cash in lieu of fractional shares of WAXS
        Common Stock is solely for the purpose of avoiding the expense and
        inconvenience to WAXS of issuing fractional shares and does not
        represent separately bargained-for consideration. The total cash
        consideration that will be paid in the Merger to CTI stockholders
        instead of issuing fractional shares of WAXS Common Stock will not
        exceed one percent (1%) of the total Merger Consideration that will be
        issued in the Merger.

             (xvii) Prior to the Effective Time, neither WAXS nor any Subsidiary
        of WAXS has distributed the stock of any corporation in a distribution
        of stock qualifying for Tax-free treatment under Section 355 of the
        Code.

             (xviii) The principal purposes of WAXS for participating in the
        Merger are bona fide purposes unrelated to Taxes, and the terms of this
        Agreement are the product of arm's-length negotiations.

             (xix) To the extent of the shares of WAXS Common Stock, including
        Contingent Shares, if any, that are placed in escrow under the Escrow
        Agreement for possible return to WAXS under the conditions specified in
        such Escrow Agreement and this Agreement: (1) there is a valid business
        reason for establishing the escrow arrangement; (2) the shares of WAXS
        Common Stock subject to the Escrow Agreement at the Effective Date,
        including the Contingent Shares, if any, which are issued pursuant to
        Section 1.7(d) hereunder and subsequently become subject to the Escrow
        Agreement, will each appear as issued and outstanding on the balance
        sheet of
                                      B-27
<PAGE>   370

        WAXS and such shares will be legally outstanding under applicable state
        law; (3) all dividends paid on such stock by WAXS will be distributed to
        the former CTI stockholders; (4) all voting rights of such stock held
        under the Escrow Agreement will be exercisable by the former CTI
        stockholders or on their behalf by the Shareholder Representative; (5)
        such stock will not be subject to restrictions requiring its return to
        WAXS because of the death, failure to continue employment or similar
        restrictions; (6) all such stock will be released from the Escrow
        Agreement within five (5) years after the Effective Time (except where
        there is a bona fide dispute as to whom such stock should be released);
        (7) the return of such stock to WAXS will not be triggered by an event
        the occurrence or nonoccurrence of which is within the control of the
        CTI stockholders; (8) the return of such stock to WAXS will not be
        triggered by the payment of additional Tax or reduction in Taxes paid as
        a result of an IRS audit of the CTI stockholders, Merger Sub or WAXS
        either (x) with respect to the Merger or (y) when the Merger involves a
        related person within the meaning of Section 267(c)(4) of the Code; (9)
        the mechanism for the calculation of the number of shares of WAXS Common
        Stock to be returned to WAXS from the Escrow Fund is objective and
        readily ascertainable; and (10) at least fifty percent (50%) of the
        number of shares of WAXS Common Stock issued as of Effective Time to the
        CTI stockholders will not be subject to the Escrow Agreement or the
        Expense Fund.

             (xx) As to the Contingent Shares, if any, which may be issued by
        WAXS pursuant to Section 1.7(d) hereunder: (1) all the Contingent Shares
        will be issued by WAXS pursuant to Section 1.7(d) of this Agreement
        within five (5) years from the Effective Time and as to any Contingent
        Shares which are placed in escrow under the Escrow Agreement, such
        Contingent Shares will be released from the Escrow Agreement within five
        (5) years after the Effective Time (except where there is a bona fide
        dispute as to whom such stock should be released); (2) there is a valid
        business reason for the provisions in Section 1.7(d) concerning the
        possible issuance of Contingent Shares; (3) the maximum number of
        Contingent Shares that may be issued is stated hereunder; (4) at least
        fifty percent (50%) of the maximum number of shares of WAXS Common Stock
        (inclusive of the Contingent Shares) will be issued as of the Effective
        Time pursuant to Section 1.7(c) hereunder; (5) the Section 1.7(d)
        provisions concerning the possible right to receive Contingent Shares
        after the Effective Time prohibit assignment of such rights except by
        operation of law; (6) the Section 1.7(d) provisions can give rise only
        to the receipt of additional WAXS Common Stock; (7) such stock issuance
        will not be triggered by an event the occurrence or nonoccurrence of
        which is within the control of the CTI stockholders; (8) such stock
        issuance will not be triggered by the payment of additional Tax or
        reduction in Taxes paid as a result of an IRS audit of the CTI
        shareholders or WAXS either (x) with respect to the Merger or (y) when
        the Merger involves related persons within the meaning of Section
        267(c)(4) of the Code; and (9) the mechanism in Section 1.7(d) hereunder
        for the calculation of Contingent Shares to be issued is objective and
        readily ascertainable.

             (xxi) To the knowledge of WAXS, there is a valid business reason
        for the escrow of shares of WAXS Common Stock comprising the Expense
        Fund pursuant to Section 2.14 of this Agreement, and to the knowledge of
        WAXS, the escrow provisions of Section 2.14 satisfy the specific
        requirements of Section 3.06 of IRS Revenue Procedure 77-37, as it has
        been amplified and superseded by the IRS.

                                   ARTICLE VI

                             ADDITIONAL AGREEMENTS

     6.1 Preparation of Proxy Statement: Stockholders Meetings.

          (a) As promptly as reasonably practicable following the date hereof,
     WAXS shall prepare and file with the Securities and Exchange Commission
     (the "SEC") materials which shall constitute its proxy statement and
     prospectus in connection with the WAXS Stockholders Meeting (such proxy
     statement and prospectus, and any amendments or supplements thereto, the
     "Proxy Statement/Prospectus") and WAXS shall prepare and file a
     registration statement on Form S-4 with respect to the issuance of all WAXS
     Common Stock in the Merger, including, without limitation, the Contingent
     Shares and the shares of WAXS Common Stock issuable to the holders of CTI
     Preferred Stock as contemplated by Section 2.6(b) (the "Registration
     Statement"). The Proxy Statement/Prospectus will be included in and will
     constitute a part of the Registration Statement as WAXS's prospectus. The
     Registration Statement and the Proxy Statement/Prospectus shall comply as
     to form in all material respects with the applicable provisions of the
     Securities Act and the Exchange Act and the rules and regulations
     thereunder. WAXS shall use reasonable efforts to have the Registration
     Statement declared effective by the SEC as promptly as reasonably
     practicable after filing with the SEC and to keep the Registration
     Statement effective as long as is necessary to consummate the Merger and
     the actions contemplated thereby. CTI shall use its reasonable best efforts
     to cooperate with and assist WAXS in connection with the preparation and
     amendment of the Proxy Statement/Prospectus and the Registration Statement.
     WAXS will provide CTI with a
                                      B-30
<PAGE>   373

     reasonable opportunity to review and comment on any amendment or supplement
     to the Registration Statement prior to filing such with the SEC, and will
     provide CTI with a copy of all such filings made with the SEC. WAXS will
     use reasonable efforts to cause the Joint Proxy Statements/Prospectus to be
     mailed to WAXS's stockholders as promptly as practicable after the
     Registration Statement is declared effective under the Securities Act. WAXS
     shall also take any action (other than qualifying to do business in any
     jurisdiction in which it is not now so qualified or to file a general
     consent to service of process) required to be taken under any applicable
     state securities laws in connection with the issuance of WAXS Common Stock
     and CTI shall furnish all information concerning CTI and the holders of CTI
     Capital Stock as may be reasonably requested in connection with any such
     action. WAXS will advise CTI promptly after it receives notice thereof, of
     the time when the Registration Statement has become effective, the issuance
     of any stop order or the suspension of the qualification of the WAXS Common
     Stock issuable in connection with the Merger for offering or sale in any
     jurisdiction or any request by the SEC for amendment of the Registration
     Statement. If at any time prior to the Effective Time any information
     relating to WAXS or CTI, or any of their respective affiliates, officers or
     directors, should be discovered by WAXS or CTI which should be set forth in
     an amendment or supplement to the Registration Statement or the Proxy
     Statement/Prospectus so that any of such documents would not include any
     misstatement of a material fact or omit to state any material fact
     necessary to make the statements therein, in light of the circumstances
     under which they were made, not misleading, the party which discovers such
     information shall promptly notify the other party hereto and, to the extent
     required by law, rules or regulations, an appropriate amendment or
     supplement describing such information shall be promptly filed with the SEC
     and disseminated to the stockholders of WAXS and CTI.

          (b) CTI shall, as promptly as reasonably practicable following the
     execution of this Agreement, (i) duly take all lawful action to call, give
     notice of, convene and hold a meeting of its stockholders (which meeting
     the parties intend to be held no later than 30 days following the date on
     which the Registration Statement has been declared effective by the SEC)
     for the purpose of obtaining or (ii) duly take all lawful action to obtain
     by written consent pursuant to the CGCL, the required vote of its
     stockholders with respect to the actions contemplated by this Agreement and
     shall take all lawful action to solicit the adoption of this Agreement by
     the stockholders of CTI by written consent or otherwise. The Board of
     Directors of CTI shall recommend adoption of this Agreement by the
     stockholders of CTI and shall not withdraw, modify or materially qualify in
     any manner adverse to WAXS such recommendation or take any action or make
     any statement materially inconsistent with such recommendation
     (collectively, an "Adverse Change in the CTI Recommendation"); provided,
     however, that the foregoing shall not prohibit accurate disclosure of
     factual information regarding the business, financial condition or results
     of operations of WAXS or CTI or the fact that an Acquisition Proposal (as
     defined in Section 6.4) has been made, the identity of the party making
     such proposal or the material terms of such proposal (provided, that the
     Board of Directors of CTI does not withdraw, modify or materially qualify
     in any manner adverse to WAXS its recommendation) in the Registration
     Statement or the Proxy Statement/Prospectus, to the extent such
     information, facts, identity or terms is required to be disclosed therein
     under applicable law.

          (c) WAXS shall, as promptly as reasonably practicable following the
     execution of this Agreement, duly take all lawful action to call, give
     notice of, convene and hold a meeting of its stockholders (the "WAXS
     Stockholders Meeting") (which meeting the parties intend to be held no
     later than 30 days following the date on which the Registration Statement
     has been declared effective by the SEC) for the purpose of obtaining the
     required vote of its stockholders with respect to the transactions
     contemplated by this Agreement and shall take all lawful action to solicit
     the approval of the transactions contemplated hereby by the stockholders of
     WAXS. The Board of Directors of WAXS shall recommend approval of the
     transactions contemplated hereby by the stockholders of WAXS and shall not
     withdraw, modify or materially qualify in any manner adverse to CTI such
     recommendation or take any action or make any statement in connection with
     the WAXS Stockholders Meeting materially inconsistent with such
     recommendation; provided, however, that the
                                      B-31
<PAGE>   374

     foregoing shall not prohibit accurate disclosure of factual information
     regarding the business, financial condition or operations of WAXS or CTI.

     6.2 Access to Information.  Upon reasonable notice, each of CTI and WAXS
shall (and shall cause its Subsidiaries to) afford to the officers, employees,
accountants, counsel, financial advisors and other representatives of the other
parties hereto reasonable access during normal business hours, during the period
prior to the Effective Time, to all its properties, books, contracts,
commitments, records, officers and employees and, during such period, each of
CTI and WAXS shall (and shall cause its Subsidiaries to) furnish promptly to the
other parties hereto (a) a copy of each report, schedule, registration statement
and other document filed, published, announced or received by it during such
period pursuant to the requirements of federal or state securities laws, as
applicable (other than documents which such party is not permitted to disclose
under applicable law), and (b) consistent with its legal obligations, all other
information concerning it and its business, properties and personnel as such
other party may reasonably request; provided, however, that either CTI or WAXS
may restrict the foregoing access to the extent that any law, treaty, rule or
regulation of any governmental entity applicable to such party requires such
party or its Subsidiaries to restrict access to any properties or information.
The parties will hold any such information which is non-public in confidence to
the extent required by, and in accordance with, the provisions of the
Confidentiality Agreement, dated January 6, 2000, between CTI and WAXS (the
"Confidentiality Agreement"). Any investigation by WAXS or CTI shall not affect
the representations and warranties made herein of CTI or WAXS, as the case may
be.

     6.3 Reasonable Efforts.

          (a) Subject to the terms and conditions of this Agreement, each party
     will use 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 the Merger and the other
     transactions contemplated by this Agreement as soon as practicable after
     the date hereof, including (i) preparing and filing as promptly as
     practicable all documentation to effect all necessary applications,
     notices, petitions, filings, and other documents and to obtain as promptly
     as practicable all consents, waivers, licenses, orders, registrations,
     approvals, permits and authorizations necessary or advisable to be obtained
     from any third party and/or any governmental entity in order to consummate
     the Merger or any of the other transactions contemplated by this Agreement
     and (ii) taking all reasonable steps as may be necessary to obtain all such
     material consents, waivers, licenses, registrations, permits,
     authorizations, tax rulings, orders and approvals. The parties each shall
     keep the other apprised of the status of matters relating to completion of
     the transactions contemplated hereby, including promptly furnishing the
     other with copies of notices or other communications received by it or any
     of its Subsidiaries or affiliates from any governmental entity or third
     party with respect to the Merger or any of the other transactions
     contemplated by this Agreement, in each case, to the extent permitted by
     law or regulation or any applicable confidentiality agreements existing on
     the date hereof.

          (b) The parties shall promptly prepare and file any required
     notifications with the United States Department of Justice (the "DOJ") and
     the Federal Trade Commission (the "FTC") as required by the
     Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
     Act"). The parties shall cooperate with each other in connection with the
     preparation of such notifications and related matters, including sharing
     information concerning sales and ownership and such other information as
     may be needed to complete such notification, and providing a copy of such
     notifications to the other prior to filing; provided, that WAXS and CTI
     shall have the right to redact any dollar revenue information from the
     copies of such notifications provided to the other parties. The parties
     shall keep all information about the other obtained in connection with the
     preparation of such notification confidential pursuant to the terms of the
     Confidentiality Agreement. Each party shall pay the filing fee required
     under the regulations promulgated pursuant to the HSR Act with respect for
     the notification for which such party is the "Acquiring Person" (as defined
     in the regulations promulgated to the HSR Act).

     6.4 Acquisition Proposals.  Without the prior written consent of WAXS,
pending the Closing, CTI agrees that neither it nor any of its Subsidiaries
shall, and that it shall cause its employees, officers, directors, affiliates,
agents and representatives (including any investment banker, financial advisor,
attorney or accountant retained by any of them) not to, directly or indirectly,
initiate, solicit, encourage or knowingly facilitate (including by way of
furnishing information or engaging in discussions or negotiations) any inquiries
or the making of any proposal or offer with respect to a merger, reorganization,
share exchange, consolidation, business combination, recapitalization,
liquidation, dissolution or similar action involving CTI, or any purchase or
sale of a material portion of the assets of (including stock of Subsidiaries) of

that neither it nor any of its Subsidiaries shall, and that it shall cause it
and its Subsidiaries' officers, directors, affiliates, employees, agents and
representatives (including any investment banker, financial advisor, attorney or
accountant retained by it or any of its Subsidiaries) not to, directly or
indirectly, have any discussion with or provide any confidential information or
data to any Person relating to an Acquisition Proposal, or engage in any
negotiations concerning an Acquisition Proposal, or knowingly facilitate any
effort or attempt to make or implement an Acquisition Proposal or accept an
Acquisition Proposal. CTI agrees that it and its Subsidiaries will, and will
cause its officers, directors, affiliates, employees, agents and representatives
to, immediately cease and cause to be terminated any activities, discussions or
negotiations existing as of the date of this Agreement with any parties
conducted heretofore with respect to any Acquisition Proposal. CTI agrees that
it will promptly inform its directors, officers, affiliates, key employees,
agents and representatives of the obligations undertaken in this Section 6.4.

     6.5 Fees and Expenses.  All Expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be paid by the party
incurring such Expenses. As used in this Agreement, "Expenses" includes all
out-of-pocket expenses (including all fees and expenses of counsel, accountants,
investment bankers, experts and consultants to a parry hereto and its
affiliates) incurred by a party or on its behalf in connection with or related
to the authorization, preparation, negotiation, execution and performance of
this Agreement and the transactions contemplated hereby.

     6.6 Public Announcements.  Neither WAXS nor CTI shall, without the prior
consent of the other party, issue a press release or any other public statement
with respect to this Agreement or the transactions contemplated hereby except
pursuant to a joint communications plan, unless otherwise required by applicable
law or by obligations pursuant to any listing agreement with or rules of any
securities exchange, in which case the parties shall use reasonable efforts to
consult with each other before issuing any press release or otherwise making any
public statement with respect to this Agreement or the transactions contemplated
hereby.

     6.7 Listing.  So long as WAXS Common Stock is quoted on the Nasdaq or
listed on any national securities exchange, WAXS, if permitted by the rules of
such system or exchange, will quote or list and keep quoted or listed on such

WAXS shall not voluntarily cause or take any steps to voluntarily cause WAXS
Common Stock to fail to be quoted on the Nasdaq or a national securities
exchange.

     6.8 Termination of Tax Sharing Agreements.  As of the Effective Time, CTI
shall cause all Tax Sharing Agreements to which CTI or any of its Subsidiaries
is a party to be terminated and of no further force and effect after the
Effective Time, thereby extinguishing any rights or obligations of any party
thereunder.

     6.9 Bridge Financing.  WAXS agrees to make funds available to Borrower (as
defined in that certain Participation Agreement, of even date herewith, between
Foothill Capital Corporation and WAXS (the "Participation Agreement")) on and
subject to the terms and conditions set forth in the Participation Agreement.

     6.10 Tax Treatment; Plan of Reorganization.  This Agreement is intended to
constitute a "plan of reorganization" within the meaning of Treas. Reg.
sec.1.368-2(g). During the period from the date of this
                                      B-33
<PAGE>   376

Agreement through the Effective Time, unless the parties shall otherwise agree
in writing, none of WAXS, CTI or any of their respective Subsidiaries shall
knowingly take or fail to take any action which action or failure to act which
could reasonably be expected to cause the Merger to fail to qualify as a
"reorganization" within the meaning of Section 368(a) of the Code. After the
Merger and pursuant to the plan of reorganization set forth in this Agreement,
WAXS expects to transfer some or all of the assets of the Surviving Corporation
in a manner permitted under Section 368(a)(2)(C) of the Code and Treas. Reg.
sec.1.368-2(k). WAXS and CTI agree to treat the Merger as a reorganization
within the meaning of Section 368(a) of the Code. To this end, none of WAXS, CTI
nor Merger Sub, nor, after the Merger, the Surviving Corporation will take any
position on any federal, state or local income or franchise Tax Return, or take
any other Tax reporting position that is inconsistent with the treatment of the
Merger as a reorganization within the meaning of Sections 368(a)(1)(A) and
368(a)(2)(D) of the Code, unless otherwise required by a "determination" (as
defined in Section 1313(a)(1) of the Code) or by applicable state or local
income or franchise Tax law.

     6.11 Directors' and Officers' Indemnification and Insurance.

          (a) From the Effective Time through the sixth (6th) anniversary of the
     date on which the Effective Time occurs, WAXS shall indemnify and hold
     harmless each present (as of the Effective Time) or former officer or
     director of CTI and its Subsidiaries (the "Indemnified Parties"), against
     all claims, losses, liabilities, damages, judgments, fines and reasonable
     fees, costs and expenses, including attorneys' fees and disbursements
     (collectively, "Costs"), incurred in connection with any claim, action,
     suit, proceeding or investigation, whether civil, criminal, administrative
     or investigative, arising out of or pertaining to (i) the fact that the
     Indemnified Party is or was an officer or director of CTI or any of its
     Subsidiaries or (ii) matters existing or occurring at or prior to the
     Effective Time (including those related to this Agreement and the
     transactions and actions contemplated hereby), whether asserted or claimed
     prior to, at or after the Effective Time, to the fullest extent permitted
     under applicable law; provided that no Indemnified Party may settle any
     such claim without the prior approval of WAXS (which approval shall not be
     unreasonably withheld or delayed). Each Indemnified Party will be entitled
     to advancement of expenses incurred in the defense of any claim, action,
     suit, proceeding or investigation from WAXS within ten (10) business days
     of receipt by WAXS from the Indemnified Party of a request therefor;
     provided that any person to whom expenses are advanced provides an
     undertaking, to the extent required by the CGCL, to repay such advances if
     it is ultimately determined that such person is not entitled to
     indemnification.

          (b) WAXS shall maintain, at no expense to the beneficiaries, in effect
     for six years from the Effective Time the current policies of the
     directors' and officers' liability insurance maintained by CTI with respect
     to matters existing or occurring at or prior to the Effective Time
     (including the transactions contemplated by this Agreement); provided that
     WAXS may substitute therefor policies of at least the same coverage
     containing terms and conditions which are not materially less advantageous
     to any beneficiary thereof; and provided, further, that in no event shall
     WAXS be required to pay annual premiums for such insurance in excess of
     125% of the annual premiums currently paid by CTI for such insurance.
     Notwithstanding the foregoing, if the insurance policies that WAXS would be
     required to maintain pursuant to this Section 6.11(b) would require the
     payment of aggregate annual premiums in excess of 125% of the aggregate
     annual premiums in effect under such policies of CTI as of the date hereof
     (the "CTI Policies"), then WAXS shall be obligated to use commercially
     reasonable efforts to obtain and maintain such substitute policies of
     insurance as are the best available as to amount and other coverage terms
     and conditions for annual premiums equal to 125% of the aggregate annual
     premiums in respect of the CTI Policies.

          (c) Notwithstanding anything herein to the contrary, if any claim,
     action, suit, proceeding or investigation (whether arising before, at or
     after the Effective Time) is made against any Indemnified Party, on or
     prior to the sixth (6th) anniversary of the Effective Time, the provisions
     of this Section 6.11 shall continue in effect until the final disposition
     of such claim, action, suit, proceeding or investigation.
                                      B-34
<PAGE>   377

          (d) The covenants contained in this Section 6.11 are intended to be
     for the benefit of, and shall be enforceable by, each of the Indemnified
     Parties and their respective heirs and legal representatives and shall not
     be deemed exclusive of any other rights to which an Indemnified Party is
     entitled, whether pursuant to law, contract or otherwise.

          (e) In the event that WAXS or any of its 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 or conveys all or substantially all of its
     properties and assets to any person, then, and in each such case, proper
     provision shall be made so that the successors or assigns of WAXS or the
     purchaser of such properties and assets shall succeed to the obligations
     set forth in this Section 6.11.

     6.12 Merger Sub Stockholder Resolutions.  Pending the Closing, WAXS shall
not rescind or modify in any material respect the Merger Sub Stockholder
Resolutions.

     6.13 Compliance with Dissenters' Rights Statute.  CTI shall comply with all
procedures and requirements applicable to CTI under Chapter 13 of the CGCL.

     6.14 Good Faith.  The parties shall perform and exercise their respective
obligations and rights provided for hereunder in good faith.

     Corporation; provided, however, that the provisions of this Section 7.2(c)
     shall not be available to WAXS if WAXS's failure to fulfill its obligations
     pursuant to Section 6.3 shall have been the cause of, or shall have
     resulted in, the failure to obtain any such consent or approval.

          (d) No Material Change.  CTI and its Subsidiaries, taken as a whole,
     shall not have suffered, since the date hereof, a Material Adverse Effect,

     or the Surviving Corporation; provided, however, that the provisions of
     this Section 7.2(f) shall not be available to WAXS if its failure to
     fulfill its obligations pursuant to Section 6.3 shall have been the cause
     of, or shall have resulted in any such order or injunction.

          (g) Trading Price.  The average of the closing prices of WAXS Common
     Stock as reported on the Nasdaq for the ten (10) consecutive trading days
     ending at the close of trading on the second (2nd) trading day preceding

     Merger and the transactions contemplated hereby shall have been obtained,
     except where the failure to obtain any such consent or approval would not
     have a Material Adverse Effect on WAXS or the Surviving Corporation;
     provided, however, that the provisions of this Section 7.3(c) shall not be

                                  ARTICLE VIII

            POST-CLOSING INDEMNIFICATION; SHAREHOLDER REPRESENTATIVE

     8.1 Remedies.  Subject to the terms of this Article VIII, from and after
the Effective Time, WAXS shall be indemnified and held harmless from and against
any and all claims, losses, liabilities, damages, costs (including court costs)
and expenses (including reasonable attorneys' and accountants' fees) suffered or
incurred by WAXS, its successors or assigns, and their respective officers,
employees, consultants and agents (the "WAXS Protected Parties") (hereinafter
"Loss" or "Losses"), as a result of, or with respect to, (i) except as otherwise
provided in Section 8.2, any breach or inaccuracy of any representation or
warranty of CTI set forth in this Agreement (without regard to any Material
Adverse Effect qualification contained in any such representation or warranty,
except such qualification contained in the representation and warranty in
Section 3.18(a)), whether such breach or inaccuracy exists or is made on the
date of this Agreement or as of the Closing Date; (ii) any breach or inaccuracy

imposition of the suspended $17.6 million fine, or other monetary penalty,
imposed in connection with or related to the matter described in item 1 of

     8.2 Indemnity Claims.

          (a) Survival.  The representations and warranties of CTI contained
     herein or in any certificate or other document delivered pursuant hereto or
     in connection herewith shall not be extinguished by the Closing but shall
     survive the Closing, subject to the limitations set forth in Section 8.2(b)
     hereof with respect to the time periods within which claims for indemnity
     must be asserted, and the covenants and agreements of the parties contained
     herein shall survive without limitation as to time except as may be
     otherwise specified herein. Notwithstanding the foregoing, none of the
     representations and warranties of CTI contained in Section 3.16(g) hereof
     or in the CTI certificate required pursuant to Section 7.2(a) with respect
     to Section 3.16(g) hereof shall survive the Closing and no WAXS Protected
     Party shall be entitled to indemnification pursuant to this Article VIII
     for any breach or alleged breach by CTI of such representations and
     warranties. No investigation or other examination of CTI by WAXS shall
     affect the term of survival of any representation or warranty contained
     herein or in any certificate or other document delivered pursuant hereto or
     in connection herewith.

          (b) Time to Assert Claims.  All claims for indemnification hereunder
     shall be asserted no later than one (1) year after the Effective Time
     provided; however, that if a notice of claim which conforms, in all
     material respects, as to form and substance with the requirements set forth
     in Section 8.4 is given pursuant to Section 8.4 prior to such one-year
     anniversary of the Effective Time, such representation or warranty shall
     continue indefinitely with respect to the claims in such notice until such
     claims are resolved pursuant to this Article VIII. Nothing herein shall be
     deemed to prevent a WAXS Protected Party from making a claim for a Loss
     hereunder for potential or contingent claims or demands provided the notice
     of Loss sets forth the specific basis for any such potential or contingent
     claim or demand to the extent then feasible and the party making the claim
     has reasonable grounds to believe that such a claim or demand may become
     actual.

     8.3 Deductible.  Notwithstanding any other provision hereof, the WAXS
Protected Parties shall make no claim against CTI for indemnification hereunder
(except pursuant to Section 8.1(a)(iv)) unless and until the amount of each
individual Loss in excess of $150,000 (the "Subdeductible Amount") exceeds
$3,000,000 in the aggregate (the "Deductible Amount"), in which event the WAXS
Protected Parties may claim indemnification for the amount of such Losses (in
each case net of the Subdeductible Amount) in excess of the Deductible Amount.

     8.4 Notice of Claim.  A WAXS Protected Party shall notify the Shareholder
Representative (as defined in Section 8.7), in writing, of any claim for
indemnification, specifying in reasonable detail the nature of the Loss, and, if
known, the amount, or an estimate of the amount, of the liability arising
therefrom. The WAXS Protected Party shall provide to the Shareholder
Representative as promptly as practicable thereafter such information and
documentation as may be reasonably requested to support and verify the claim
asserted, so long as such disclosure would not violate the attorney-client
privilege of the WAXS Protected Party.

     8.5 Defense.  If the facts pertaining to a Loss arise out of the claim of
any third party, or if there is any claim against a third party available by
virtue of the circumstances of the Loss, the Shareholder Representative may
assume the defense or the prosecution thereof by prompt written notice to the
WAXS Protected Party, including the employment of counsel or accountants, at its
cost and expense. The WAXS Protected Party shall have the right to employ
counsel separate from counsel employed by the Shareholder Representative in any
such action and to participate therein, but the fees and expenses of such
counsel employed by the WAXS Protected Party shall be at its expense. The
Shareholder Representative shall not be liable for any settlement of any such
claim effected without its prior written consent, which shall not be
unreasonably withheld or delayed. The Shareholder Representative shall not agree
to a settlement of any claim which provides for any relief, other than the
payment of monetary damages, which would have a material precedential impact or
effect on the business or financial condition of any WAXS Protected Party
without the WAXS Protected Party's prior written consent. Whether or not the
Shareholder Representative chooses to so defend or prosecute such claim, the
parties hereto shall reasonably cooperate
                                      B-38
<PAGE>   381

in the defense or prosecution thereof and shall furnish such records,
information and testimony, and attend such conferences, discovery proceedings,
hearings, trials and appeals, as may be reasonably requested in connection
therewith. The Shareholder Representative shall be subrogated to all rights and
remedies of any WAXS Protected Party.

     8.6 Satisfaction of Obligations.  Notwithstanding anything else herein or
otherwise to the contrary (except as set forth in Section 10.1), (i) the sole
remedy of any WAXS Protected Party for any breach by CTI of a representation or
warranty of CTI hereunder shall be the right to receive indemnification from CTI
pursuant to this Article VIII and (ii) the Escrow Fund shall constitute the WAXS
Protected Parties' sole source of recovery for claims for indemnification
arising under this Article VIII, and none of CTI, its Subsidiaries or any of
their respective officers, directors, employees or shareholders shall have any
personal liability whatsoever with respect thereto.

     8.7 Shareholder Representative.

          (a) Upon approval by the stockholders of CTI of the Merger, this
     Agreement and the other transactions contemplated hereby, the stockholders
     of CTI will be deemed to have appointed, as of the Effective Time, Edward
     S. Soren (the "Shareholder Representative") as their representative under
     this Agreement and the Escrow Agreement, including for purposes of the
     indemnification obligations set forth in this Article VIII, and as
     attorney-in-fact and agent for and on behalf of such CTI stockholders with
     authority to take any and all actions and make any and all decisions
     required or permitted to be taken or made by them under this Agreement and
     the Escrow Agreement (including the settling of claims for indemnity). The
     Shareholder Representative shall have full power and authority as agent of
     the CTI stockholders to represent the CTI stockholders, and their
     successors, heirs, representatives, and assigns with respect to all matters
     arising under this Agreement and the Escrow Agreement and any other matters
     concerning the transactions contemplated by this Agreement and the Escrow
     Agreement after the Closing, and all action taken by the Shareholder
     Representative shall be binding upon the CTI stockholders and their
     successors, heirs, representatives and assigns as if expressly confirmed
     and ratified by each of them.

          (b) The Shareholder Representative shall act in good faith in
     undertaking his duties set forth herein. The Shareholder Representative,
     acting in such capacity, shall not incur any liability with respect to any
     action or inaction taken by him except those involving his own willful
     misconduct or gross negligence. The Shareholder Representative may, in all
     questions arising under this Agreement, rely on the advice of counsel and
     for anything done, omitted or suffered in good faith by the Shareholder
     Representative based on such advice, the Shareholder Representative shall
     not be liable to anyone, except to the extent such action or inaction
     involves the Shareholder Representative's own willful misconduct or gross
     negligence. Nothing set forth in this Section 8.7(b) shall in any way
     relieve the Shareholder Representative in his capacity as a CTI Stockholder
     of his obligations under this Article VIII.

          (c) In the event of the death or permanent disability of the
     Shareholder Representative or his resignation as the Shareholder
     Representative, a successor Shareholder Representative shall be appointed
     by Roger Abbott. Prompt notice of such appointment shall be delivered in
     writing by Roger Abbott to WAXS and the Escrow Agent.

                                   ARTICLE IX

                          TERMINATION PRIOR TO CLOSING

     9.1 Termination of Agreement.  This Agreement may be terminated at any time
prior to the Closing:

          (a) By mutual written consent of WAXS and CTI;

          (b) By either WAXS or CTI, if the other party shall have failed to
     comply in any material respect with any of its material covenants or
     agreements contained in this Agreement, which failure to so comply has not
     been cured within thirty (30) days following receipt by such other party of
     written
                                      B-39
<PAGE>   382

     notice of such failure to comply; provided, however, that if any such
     breach is curable by the breaching party through the exercise of the
     breaching party's reasonable efforts and for so long as the breaching party
     shall be so using its reasonable efforts to cure such breach, the
     non-breaching party may not terminate this Agreement pursuant to this
     paragraph; and provided, further, that no party shall have the right to
     terminate this Agreement pursuant to this Section 9.1(b) if such party is
     then failing to comply in any material respect with any of its covenants or
     agreements contained in this Agreement;

          (c) By either WAXS or CTI, if there has been a breach by the other
     party of any representations or warranties, which breach has not been cured
     within thirty (30) days following receipt by such other party of written
     notice of such failure to comply; provided, however, that if any such
     breach is curable by the breaching party through the exercise of the
     breaching party's reasonable efforts and for so long as the breaching party
     shall be so using reasonable efforts to cure such breach, the non-breaching
     party may not terminate this Agreement pursuant to this paragraph; and
     provided further, that this provision shall only apply to such breaches
     which would have a Material Adverse Effect on (i) WAXS (after giving effect
     to the Merger), (ii) the Surviving Corporation or (iii) WAXS (after giving
     effect to the Merger) and the Surviving Corporation;

          (d) By either CTI or WAXS, if the Effective Time shall not have
     occurred on or before October 31, 2000 (the "Termination Date"); provided,
     however, that the right to terminate this Agreement under this Section
     9.1(d) shall not be available to any party whose action or failure to
     fulfill any obligation under this Agreement has been the cause of, or
     resulted in, the failure of the Effective Time to occur on or before the
     Termination Date and any such action or failure constitutes a breach of
     this Agreement;

          (e) By either CTI or WAXS if any governmental entity (i) shall have
     issued an order, decree or ruling or taken any other action (which the
     parties shall have used their reasonable efforts to resist, resolve or
     lift, as applicable, in accordance with Section 6.3) permanently
     restraining, enjoining or otherwise prohibiting the transactions
     contemplated by this Agreement, and such order, decree, ruling, or other
     action shall have become final and nonappealable or (ii) shall have failed
     to issue an order, decree or ruling or to take any other action (which
     order, decree, ruling or other action the parties shall have used their
     reasonable efforts to obtain, in accordance with Section 6.3), which, in
     the case of each of (i) and (ii) is necessary to fulfill the conditions set
     forth in Section 7.2(f) with respect to WAXS or Section 7.3(g) with respect
     to CTI, and such denial of a request to issue such order, decree, ruling or
     take such other action shall have become final and nonappealable; provided,
     however, that the right to terminate this Agreement under this Section
     9.1(e) shall not be available to any party whose action or failure to
     fulfill any obligation under this Agreement has been the cause of such
     action or inaction and any such action or failure constitutes a breach of
     this Agreement; or

          (f) By WAXS or CTI if the adoption of this Agreement by the
     stockholders of WAXS or the stockholders of CTI shall not have been
     obtained by reason of the failure to obtain the required vote of the WAXS
     or CTI stockholders, in each case, upon the taking of such vote.

     9.2 Effect of Termination.  In the event of any termination of this
Agreement by either CTI or WAXS, as provided in Section 9.1, this Agreement
shall forthwith become void and there shall be no liability or obligation on the
part of WAXS or CTI or their respective officers or directors except with
respect to Sections 6.2, 6.5, 6.6, this Section 9.2 and Section 10.7, which
provisions shall survive such termination and except that, notwithstanding
anything to the contrary contained in this Agreement, neither WAXS nor CTI shall
be relieved or released from any liabilities or damages arising out of its
breach of this Agreement.

     9.3 Amendment.  This Agreement may be amended by CTI and WAXS, by action
taken or authorized by their respective Boards of Directors or representatives
or authorized officers, at any time before or after approval of the matters
presented in connection with the Merger by the stockholders of CTI and WAXS,
but, after any such approval, no amendment shall be made which by law or in
accordance with the rules of any relevant stock exchange or automatic quotations
system requires further
                                      B-40
<PAGE>   383

approval by such stockholders without such further approval. This Agreement may
not be amended except by an instrument in writing signed on behalf of each of
CTI and WAXS.

     9.4 Extension, Waiver.  At any time prior to the Effective Time, the
parties hereto, by action taken or authorized by their respective Boards of
Directors, representatives or authorized officers, may, to the extent legally
allowed, (i) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (ii) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto and (iii) waive compliance with any of the agreements or
conditions contained herein. Any agreement on the part of a party hereto to any
such extension or waiver shall be valid only if set forth in a written
instrument signed on behalf of such party. The failure of any party to this
Agreement to assert any of its rights under this Agreement or otherwise shall
not constitute a waiver of those rights.

                                   ARTICLE X

                                 MISCELLANEOUS

shall survive the Closing. Notwithstanding anything in this Agreement to the
contrary, nothing contained in Article VIII or in any other provision hereof
shall limit, modify or otherwise affect the rights or remedies of WAXS or CTI,
at law or in equity, arising prior to the Effective Time or against any person
or entity for fraud or intentional misrepresentation.

     10.2 Entire Agreement.  This Agreement (including the Schedules and
Exhibits), the Escrow Agreement and the Confidentiality Agreement constitute the

provided, however, that this provision is not intended to abrogate any other
written agreement between the parties executed with or after this Agreement.

     10.3 Parties Bound by Agreement; Successors and Assigns.  The terms,
conditions and obligations of this Agreement shall inure to the benefit of and
be binding upon the parties hereto and the respective successors and assigns

rights, duties or obligations hereunder or any part thereof to any other person
or entity. WAXS may assign its rights and duties hereunder in whole or in part
(before or after the Effective Time) to one or more affiliates but if it does
so, it shall remain liable for all WAXS' obligations hereunder.

     10.4 Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall for all purposes be deemed to be an original
and all of which shall constitute the same instrument.

     10.5 Headings.  The headings of the Sections and paragraphs of this
Agreement are inserted for convenience only and shall not be deemed to
constitute part of this Agreement or to affect the construction thereof.

     10.6 Modification and Waiver.  Any of the terms or conditions of this
Agreement may be waived in writing at any time by the party which is entitled to
the benefits thereof. No waiver of any of the provisions of this Agreement shall

        provided further, that (i) this provision shall only apply to such
        breaches which would have a Material Adverse Effect on (A) WAXS (after
        giving effect to the Merger), (B) the Surviving Corporation or (C) WAXS
        (after giving effect to the Merger) and the Surviving Corporation and
        (ii) WAXS shall not have the right to terminate this Agreement pursuant
        to this Section 9.1(c) if CTI's breach of any of its representations and
        warranties stated herein is caused by or results from any act or
        omission of WAXS pursuant to the Management Agreement occurring from and
        after the date of the Management Agreement through and including the
        Closing Date;"



          (j) Section 9.1(d).  Section 9.1(d) of the Merger Agreement is hereby
     amended by changing the date "October 31, 2000" therein to "December 31,

                               February 11, 2000

Board of Directors
World Access, Inc.
945 East Paces Ferry Road
Suite 2200
Atlanta, GA 30326

Dear Sirs:

     You have requested our opinion as to the fairness from a financial point of
view to World Access, Inc. (the "Company") of the consideration to be paid by
the Company pursuant to the terms of the Agreement and Plan of Merger, dated as
of February 11, 2000 (the "Agreement"), by and among the Company, STI Merger
Co., a wholly-owned subsidiary of the Company ("Merger Sub"), and STAR
Telecommunications, Inc. ("STAR"), pursuant to which STAR will be merged (the
"Merger") with and into Merger Sub.

     Pursuant to the Agreement, each share of common stock, par value $0.001 per
share, of STAR ("STAR Common Stock") issued and outstanding will be converted
into, at the election of the Company by written notice to STAR prior to the
Closing, the following consideration (the "Merger Consideration"): (i) the right
to receive the number of shares of common stock, par value $.01 per share, of
the Company ("WAXS Common Stock") obtained by solving for "X" in the following
formula (the "Exchange Ratio"): X = (7.81 + Z) / 20.00, or (ii) the right to
receive, at the option of the holder, either (x) the number of shares of WAXS
Common Stock equal to the Exchange Ratio or (y) such number of shares of WAXS
Common Stock as shall equal sixty percent (60%) of the Exchange Ratio and an
amount in cash equal to forty percent (40%) of the sum of ($7.81 + Z) (the "Cash
and Stock Election"); provided, however, that in no event shall more than
forty-five percent (45%) of the outstanding shares of STAR Common Stock receive
the Cash and Stock Election. For the purposes of the Agreement and this opinion,
(a) in determining the Exchange Ratio, "Z" shall equal the PT-1 Excess Proceeds
(as defined below) divided by the number of issued and outstanding STAR
shares/options and (b) "PT-1 Excess Proceeds" means the cash proceeds received
by STAR at the consummation of the sale of PT-1, net of all taxes, fees and
expenses in connection with the sale of PT-1 ("Net PT-1 Proceeds") in excess of
$150.0 million.

     In arriving at our opinion, we have reviewed the draft dated February 6,
2000 of the Agreement. We also have reviewed financial and other information
that was publicly available or furnished to us by the Company and STAR,
including information provided during discussions with their respective
managements. Included in the information provided during discussions with the
respective managements were certain financial projections of STAR for the period
beginning January 1, 2000 and ending December 31, 2004 prepared by the
management of the Company and certain financial projections of the Company for
the period beginning January 1, 2000 and ending December 31, 2004 prepared by
the management of the Company. In addition, we have compared certain financial
and securities data of the Company and STAR with various other companies whose
securities are traded in public markets, reviewed the historical stock prices
and trading volumes of the common stock of the Company and STAR, reviewed prices
paid in certain other business combinations and conducted such other financial
studies, analyses and investigations as we deemed appropriate for purposes of
this opinion.

     In rendering our opinion, we have relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to
us from public sources, that was provided to us by the Company and STAR or their
respective representatives, or that was otherwise reviewed by us. In particular,
we have relied upon the estimates of the management of the Company of the
operating synergies achievable as a result of the Merger. With respect to the
financial projections supplied to us, we have relied on representations that
they have been reasonably prepared on the basis reflecting the best
<PAGE>   394

currently available estimates and judgments of the management of the Company as
to the future operating and financial performance of the Company and STAR. In
addition, we have relied upon and assumed Net PT-1 Proceeds of $150.0 million
from the sale of PT-1. We have not assumed any responsibility for making any
independent evaluation of any assets of liabilities or for making any
independent verification of any of the information reviewed by us. We have
assumed that the Merger will be accounted for as a purchase under generally
accepted accounting principles and that it will qualify as a tax-free
reorganization for U.S. federal income tax purposes.

     Our opinion is necessarily based on economic, market, financial and other
conditions as they exist on, and on the information made available to us as of,
the date of this letter. It should be understood that, although subsequent
developments may affect this opinion, we do not have nay obligation to update,
revise or reaffirm this opinion. We are expressing no opinion as to the prices
at which the WAXS Common Stock will actually trade at any time. Our opinion does
not address the relative merits of the Merger and the other business strategies
being considered by the Company's Board of Directors, nor does it address the
Board's decision to proceed with the Merger. Our opinion does not constitute a
recommendation to any stockholder as to how such stockholder should vote on the
proposed transaction.

Board of Directors
World Access, Inc.
945 East Paces Ferry Road
Suite 2200
Atlanta, GA 30326

Dear Sirs:


     You have requested our opinion as to the fairness from a financial point of
view to World Access, Inc. (the "Company") of the consideration to be paid by
the Company pursuant to the terms of the Agreement and Plan of Merger, dated as
of February 11, 2000 (the "Agreement"), by and among the Company, CTI Merger
Co., a wholly-owned subsidiary of the Company ("Merger Sub"), and Communication
TeleSystems International d/b/a WorldxChange Communications, ("CTI"), pursuant
to which CTI will be merged (the "Merger") with and into Merger Sub.


     Pursuant to the Agreement, each share of common stock, par value $.01 per
share, of CTI, each share of preferred stock, Series A, no par value per share,
of CTI and each share of preferred stock, Series B, no par value per share, of
CTI, issued and outstanding, will be converted into the right to receive 0.6583
shares of common stock, par value $.01 per share, of the Company ("WAXS Common
Stock") (such shares and the Contingent Shares referred to below are referred to
as the "Merger Consideration"). In the event that the average of the closing
prices of WAXS Common Stock for the ten (10) trading-day period ending at the
close of trading on the second trading day preceding the Closing is less than
$20.38, then, in addition to the shares of WAXS Common Stock issued pursuant to
the above, each CTI stockholder who receives shares of WAXS Common Stock shall
be entitled to receive the amount, if any (the "Contingent Amount"), by which
the Target Price (as defined below) exceeds the greater of (i) the Current
Market Price (as defined below) on the first anniversary of the Effective Time
(the "Maturity Date") and (ii) $11.50, multiplied by the number of shares of
WAXS Common Stock issued to such holder pursuant to the prior sentence. The
Contingent Amount shall only be paid in shares of WAXS Common Stock (the
"Contingent Shares"), which shares shall be valued for purposes hereof at the
greater of the Current Market Price as of the Maturity Date and $11.50 and
rounded to the nearest whole share. Any and all rights in, or to receive, the
Contingent Amount shall terminate and be of no further force or effect if, at
any time on or prior to the Maturity Date, the Current Market Price is greater
than the Target Price.

     For purposes hereof, (a) the Target Price means $20.38 per share of WAXS
Common Stock; provided, however, that if the Nasdaq Composite Index (the "IXIC")
at the close of trading on the Maturity Date is eighty-five percent (85%) or
less than the "IXIC" at the close of trading on the date of the Effective Time
(the difference between one hundred percent (100%) and such percentage being
referred to as the "Market Correction Percentage"), then the Target Price shall
be reduced by a percentage equal to that portion of the Market Correction
Percentage in excess of fifteen percent (15%); and (b) the Current Market Price
means, as of any date specified herein, the average of the daily closing trading
prices of WAXS Common Stock for the twenty (20) consecutive trading days ending
at the close of trading on such date.

     In arriving at our opinion, we have reviewed the draft dated February 10,
2000 of the Agreement. We also have reviewed financial and other information
that was publicly available or furnished to us by the Company and CTI including
information provided during discussions with their respective managements.
Included in the information provided during discussions with the respective
managements were certain financial projections of CTI for the period beginning
January 1, 2000 and ending December 31, 2004 prepared by the management of the
Company, and certain financial projections of the Company for the
<PAGE>   396

period beginning January 1, 2000 and ending December 31, 2004 prepared by the
management of the Company. In addition, we have compared certain financial and
securities data of the Company and CTI with various other companies whose
securities are traded in public markets, reviewed prices paid in certain other
business combinations and conducted such other financial studies, analyses and
investigations as we deemed appropriate for purposes of this opinion.

     In rendering our opinion, we have relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to

the future operating and financial performance of the Company and CTI. We have
not assumed any responsibility for making any independent evaluation of any
assets or liabilities or for making any independent verification of any of the
information reviewed by us. We have assumed that the Merger will be accounted

                                                                February 7, 2000

Board of Directors
Star Telecommunications, Inc.
223 East De La Guerra
Santa Barbara, CA 93101

Ladies and Gentlemen:

     Deutsche Bank Securities Inc. ("Deutsche Bank") has acted as financial
advisor to Star Telecommunications, Inc. ("STAR") in connection with the
proposed merger of STAR and World Access, Inc. ("World Access") pursuant to the
Agreement and Plan of Merger (the "Merger Agreement") to be entered into among
World Access, STAR and STI Merger Co., a wholly owned subsidiary of World Access
("Acquiror Sub"), which provides, among other things, for the merger of STAR
with and into Acquiror Sub (the "Transaction"), as a result of which STAR will
become a wholly owned subsidiary of World Access. As set forth more fully in the
Merger Agreement, as a result of the Transaction, each share of the Common
Stock, par value $0.001 per share, of STAR ("STAR Common Stock") not owned
directly or indirectly by World Access or STAR will be converted into the right
to receive the "Merger Consideration" described below. The "Merger
Consideration" is (A) a number of shares of Common Stock, par value $0.01 per
share, of World Access ("World Access Common Stock") equal to a fraction (the
"Exchange Ratio") (1) the numerator of which is the sum of (a) $7.81 and (b) an
amount equal to the "PT-1 Excess Proceeds" (as defined in the Merger Agreement)
divided by the total number of issued and outstanding shares of STAR Common
Stock and shares of STAR common stock underlying issued and outstanding options
with exercise prices of $7.81 or less (the "PT-1 Excess Proceeds Per Share") and
(2) the denominator of which is $20.00; or, at the election of World Access by
written notice to STAR, (B) (1) a number of shares of World Access Common Stock
equal to 60 percent of the Exchange Ratio and (2) an amount in cash equal to 40
percent of the sum of (a) $7.81 and (b) the PT-1 Excess Proceeds Per Share. The
terms and conditions of the Transaction are more fully set forth in the Merger
Agreement.

     You have requested Deutsche Bank's opinion, as investment bankers, as to
the fairness, from a financial point of view, to the holders of STAR Common
Stock of the Merger Consideration to be received by such stockholders pursuant
to the Merger Agreement.

     In connection with Deutsche Bank's role as financial advisor to, and in
arriving at its opinion, Deutsche Bank has reviewed certain publicly available
financial and other information concerning STAR and World Access and certain
internal analyses and other information furnished to it by STAR and World
Access. Deutsche Bank has also held discussions with members of the senior
managements of STAR and World Access regarding the businesses and prospects of
their respective companies and the joint prospects of a combined company. In
addition, Deutsche Bank has (i) reviewed the reported prices and trading
activity for STAR Common Stock and World Access Common Stock, (ii) compared
certain financial and stock market information for STAR and World Access with
similar information for certain other companies whose securities are publicly
traded, (iii) reviewed the financial terms of certain recent business
combinations which it deemed comparable in whole or in part, (iv) reviewed the
terms of the February 6, 2000 draft of the Merger Agreement, and (v) performed
such other studies and analyses and considered such factors as it deemed
appropriate.

     Deutsche Bank has not assumed responsibility for independent verification
of, and has not independently verified, any information, whether publicly
available or furnished to it, concerning STAR or World Access, including,
without limitation, any financial information, forecasts or projections
considered in connection with the rendering of its opinion. Accordingly, for
purposes of its opinion, Deutsche Bank has assumed and relied upon the accuracy
and completeness of all such information and Deutsche Bank has not conducted a
physical inspection of any of the properties or assets, and has not prepared or
obtained any independent evaluation or appraisal of any of the assets or
liabilities, of STAR or World Access. With respect to the financial forecasts
and projections, including the analyses and forecasts of certain cost

                                       E-1
<PAGE>   398

savings, operating efficiencies, revenue effects and financial synergies
expected by STAR and World Access to be achieved as a result of the Transaction
(collectively, the "Synergies"), made available to Deutsche Bank and used in its
analyses, Deutsche Bank has assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
management of STAR or World Access, as the case may be, as to the matters
covered thereby. In rendering its opinion, Deutsche Bank expresses no view as to
the reasonableness of such forecasts and projections, including the Synergies,
or the assumptions on which they are based. Deutsche Bank's opinion is
necessarily based upon economic, market and other conditions as in effect on,
and the information made available to it as of, the date hereof. We undertake no
obligation to update this opinion to reflect any developments occurring after
the date hereof. We express no opinion as to the price or range of prices at
which World Access Common Stock may trade subsequent to the announcement or
consummation of the Transaction.

     For purposes of rendering its opinion, Deutsche Bank has assumed that the
final terms of the Merger Agreement would not vary from the February 6, 2000
draft that Deutsche Bank reviewed in any respect that would be material to
Deutsche Bank's analysis. Further, Deutsche Bank has assumed that, in all
respects material to its analysis, the representations and warranties of STAR,
World Access and Acquiror Sub contained in the Merger Agreement are true and
correct, STAR, World Access and Acquiror Sub will each perform all of the
covenants and agreements to be performed by it under the Merger Agreement and
all conditions to the obligations of each of STAR, World Access and Acquiror Sub
to consummate the Transaction will be satisfied without any waiver thereof.
Deutsche Bank has also assumed that all material governmental, regulatory or
other approvals and consents required in connection with the consummation of the
Transaction will be obtained and that in connection with obtaining any necessary
governmental, regulatory or other approvals and consents, or any amendments,
modifications or waivers to any agreements, instruments or orders to which
either STAR or World Access is a party or is subject or by which it is bound, no
limitations, restrictions or conditions will be imposed or amendments,
modifications or waivers made that would have a material adverse effect on STAR
or World Access or materially reduce the contemplated benefits of the
Transaction to STAR or its stockholders. In addition, you have informed Deutsche
Bank, and accordingly for purposes of rendering its opinion Deutsche Bank has
assumed, that the Transaction will be tax-free to each of the STAR, World
Access, World Access's stockholders and, to the extent they receive World Access
Common Stock, STAR's stockholders.

     In connection with our engagement, we have not been authorized by STAR or
its Board of Directors to solicit, nor have we solicited, any alternative
transactions to the Transaction.

     This opinion is addressed to, and for the use and benefit of, the Board of
Directors of STAR and is not a recommendation to the stockholders of STAR to
approve the Transaction. This opinion is limited to the fairness, from a
financial point of view, to the stockholders of STAR of the consideration to be
received by such stockholders pursuant to the Merger Agreement in the
Transaction, and Deutsche Bank expresses no opinion as to the merits of the
underlying decision by STAR to engage in the Transaction.

     Deutsche Bank will be paid a fee for its services as financial advisor to
STAR in connection with the Transaction, a substantial portion of which is
contingent upon consummation of the Transaction. We are an affiliate of Deutsche
Bank AG (together with its affiliates, the "DB Group"). One or more members of
the DB Group have, from time to time, provided investment banking, commercial
banking (including extension of credit) and other financial services to STAR and
World Access or their respective affiliates for which it has received
compensation. A portion of the proceeds of a bridge loan to be provided by World
Access to STAR pursuant to the Merger Agreement may be used to repay
indebtedness of STAR which has been extended by one or more members of the DB
Group. In the ordinary course of business, members of the DB Group may actively
trade in the securities and other instruments and obligations of STAR and World
Access for their own accounts and for the accounts of their customers.
Accordingly, the DB Group may at any time hold a long or short position in such
securities, instruments and obligations.

     Based upon and subject to the foregoing, it is Deutsche Bank's opinion as
investment bankers that, as of the date hereof, the Merger Consideration to be
received pursuant to the Merger Agreement by holders of STAR Common Stock in the
Transaction is fair, from a financial point of view, to such stockholders.

                                          Very truly yours,

                                   ARTICLE II



                               PURCHASE AND SALE



     SECTION 2.01 Purchase and Sale.  Upon the terms and subject to the
conditions set forth in this Agreement, the Seller agrees to, and to cause each
of its Subsidiaries to, sell, assign, transfer, convey and deliver the Assets to
the Purchaser or its designated affiliates, and the Purchaser agrees to purchase
and accept the Assets from the Seller and such Subsidiaries, on the Closing
Date.



     SECTION 2.02 Delivery of Instruments of Transfer.  (a) On the Closing Date,
the Seller and each of its relevant Subsidiaries shall deliver to the Purchaser
such specific assignments, bills of sale, endorsements, leases and other good
and sufficient instruments of conveyance and transfer, in form and substance
satisfactory to the Purchaser, the Seller and their respective counsel, as shall
be reasonably requested by the Purchaser to effectively vest in the Purchaser
title to all the Assets, including, but not limited to the bill of sale and
assignment and assumption agreement (including, without limitation, appropriate
assignments of trademarks, copyrights and patents, if applicable), dated the
Closing Date, substantially in the form of Exhibit A (the "Bill of Sale")
(provided that, for the avoidance of doubt, the third-party consents set forth
on Schedule 8.05 shall be the only third-party consents with respect to Material
Contracts required for Closing, provided further that the Seller and the Parent
shall use best efforts consistent with Section 2.02(b) to obtain any other
third-party consents following Closing). Simultaneously with the delivery of
such instruments and agreements, the Parent and Seller shall put the Purchaser
in actual possession and operating control of the Assets, free and clear of all
Encumbrances, except Permitted Encumbrances.



     (b) Anything in this Agreement to the contrary notwithstanding, this
Agreement shall not constitute an agreement to assign any Asset or any claim or
right or any benefit arising thereunder or resulting therefrom if such
assignment, without the consent of a third party thereto, would constitute a
breach or other contravention of such Asset or in any way adversely affect the
rights of the Purchase or the Seller thereunder. The Purchaser, the Seller and
the Parent shall use their best efforts (but without the payment of money by the
Seller, the Parent or the Purchaser) to obtain the consent of the other parties
to any such Asset or claim or right or any benefit arising thereunder for the
assignment thereof to the Purchaser as the Purchaser may request. If such
consent is not obtained, or if an attempted assignment thereof would be
ineffective or would adversely affect the rights of the Seller thereunder so
that the Purchaser would not in fact receive all such rights, the Seller, the
Parent and the Purchaser shall cooperate in a mutually agreeable arrangement
under which the Purchaser would obtain the benefits and assume the obligations
thereunder in accordance with this Agreement, including subcontracting,
sublicensing, or subleasing to the Purchaser, or under which the Seller would
enforce for the benefit of the Purchaser, with the Purchaser assuming the
Seller's obligations, any and all rights of the Seller against a third party
thereto. The Seller and the Parent shall promptly pay to the Purchaser when
received all monies received by the Seller or the Parent under any Asset or any
claim or right or any benefit arising thereunder.



     SECTION 2.03 Purchase Price; Escrow Amount.  (a) The consideration (the
"Purchase Price") to be paid to the Parent by the Purchaser for the Assets shall
be $150,000,000, which shall be paid, less the Escrow Amount and the Closing
Reduction Amount (if any), on the Closing Date in cash by wire transfer of
immediately available funds to a bank account of the Seller designated by the
Seller to the Purchaser in writing not less than two Business Days prior the
Closing. The Purchase Price is subject to adjustment as set forth in Section
2.03(b) and Section 2.04. On the Closing Date the Purchaser shall deposit the
Escrow Amount into escrow pursuant to a mutually agreed-upon escrow agreement
(the "Escrow Agreement"). The Escrow Amount, less any amounts thereof that are
subject to, or previously paid to the Purchaser in respect of, claims for
indemnification by the Purchaser hereunder, shall be released to the Seller as
to 25% thereof on each 6-month anniversary of the Closing; provided that 100% of
the Escrow Amount, less any amounts thereof that are subject to, or previously
paid to the Purchaser in respect of, claims for indemnification that have been
made by the Purchaser under this Agreement, shall be released to the Seller upon
the closing of the Parent Merger and the express written assumption by Waxs of
the Seller's and the Parent's indemnification and other obligations hereunder.

     (b) (i) Five Business Days prior to Closing the Parent and the Seller shall
deliver to the Purchaser their best estimate of the cash, accounts payable and
accounts receivable (together with an estimate of sales and purchases of the
Company for the thirty days prior to Closing and such information reasonably
necessary for the Purchaser to evaluate all of the foregoing items) (the
"Estimated Closing Statement") of the Company as of such date. During the three
Business Days commencing with the delivery of the the Estimated Closing
Statement the parties shall, together with their respective accountants, work
together to agree upon the calculation set forth in the Estimated Closing
Statement and whether the Days Accounts Payable and Receivable for the 30 days
prior to Closing vary materially from the Days Accounts Payable and Receivable
for the 30 days prior to December 31, 1999. If the parties reach agreement as to
the foregoing calculation and agree that the respective Days Accounts Payable
and Receivable for the foregoing periods vary materially, the Purchase Price
shall be automatically reduced to the extent such variance would result in lower
accounts receivable being purchased and/or higher accounts payable being assumed
by the Purchaser, such reduction to be calculated based on the accounts
receivable and accounts payable of the Seller that would have existed at Closing
had such variance not existed, and such amount shall be deemed the "Closing
Reduction Amount". If the parties are unable to reach agreement by the date that
is two Business Days prior to Closing, the parties shall submit the matter for
resolution by an Independent Third Party, together with the parties' respective
calculations. The Independent Third Party shall be instructed to render its
determination of the correct Estimated Closing Statement and the amount, if any,
by which the Purchase Price should be reduced (such amount then being deemed the
"Closing Reduction Amount") within such two Business Day period and by Closing,
and such determination shall be binding on the parties at Closing. The costs and
expenses of the Independent Third Party hereunder shall be borne equally by the
parties hereto.



     (ii) As promptly as practicable, but no later than 60 days, after the
Closing Date, the Parent will cause to be prepared and delivered to the
Purchaser the Closing Balance Sheet (as defined below), and a certificate signed
by the Controller or Chief Financial Officer of Seller based on such Closing
Balance Sheet setting forth the Parent's calculation of Net Assets (as defined
below). The Closing Balance Sheet (the "Closing Balance Sheet") shall (x) fairly
present the Assets and Assumed Liabilities as at the close of business on the
Closing Date in accordance with GAAP applied on a basis consistent with those
used in the preparation of the Balance Sheet, any (y) include line items
substantially consistent with those in the Balance Sheet. "Net Assets" shall
mean an amount equal to (i) the Assets minus (ii) the Assumed Liabilities.



     (c) If the Purchaser disagrees with the Parent's calculation of Net Assets
delivered pursuant to Section 2.03(b)(ii) the Purchaser may, within 60 days
after delivery of the documents referred to in Section 2.03(b)(ii), deliver a
notice to the Parent disagreeing with such calculation and setting forth the
Purchaser's calculation of such amount. Any such notice of disagreement shall
specify those items or amounts as to which the Purchaser disagrees.



     (d) If a notice of disagreement shall be duly delivered pursuant to Section
2.03(c), the Purchaser and the Parent shall, during the 30 days following such
delivery, use their best efforts to reach agreement on the disputed items or
amounts in order to determine, as may be required, the amount of Net Assets,
which amount shall not be more than the amount thereof shown in the Parent's
calculations delivered pursuant to Section 2.03(b)(ii) nor less than the amount
thereof shown in the Purchaser's calculation delivered pursuant to Section
2.03(c). If during such period, the Purchaser and the Parent are unable to reach
such agreement, they shall promptly thereafter cause the Independent Third Party
promptly to review this Agreement and the disputed items or amounts for the
purpose of calculating Net Assets. In making such calculation, the Independent
Third Party shall consider only those items or amounts in the Closing Balance
Sheet or the Parent's calculation of Net Assets as to which the Purchaser has
disagreed as specified in the notice delivered pursuant to Section 2.03(c). The
Independent Third Party shall deliver to the Purchaser and the Parent, as
promptly as practicable, a report setting forth such calculation. Such report
shall be final and binding upon the Purchaser and the Parent and the Seller. The
cost of such review and report shall be borne (i) by the Parent if the
difference between Final Net Assets (as defined in Section 2.04(a)) and Net
Assets as set forth in the Parent's calculation of Net Assets delivered


                                       F-6
<PAGE>   406


pursuant to Section 2.03(b)(ii) is greater than the difference between Final Net
Assets and Net Assets as set forth in the Purchaser's calculation of Net Assets
delivered pursuant to Section 2.03(c), (ii) by the Purchaser if the first such
difference is less than the second such difference and (iii) otherwise equally
by the Purchaser and the Parent.



     (e) The Purchaser, the Parent and the Seller agree that they will, and
agree to cause their respective independent accountants to, cooperate and assist
in the preparation of the Closing Balance Sheet and the calculation of Net

the amount of such excess. If Final Net Assets exceeds Base Net Assets, the
Purchaser shall pay to the Parent, in the manner and with interest as provided

further that the Parent shall receive a credit for any payments to be made by it
under this Section 2.04(a) of up to $10,366,372 (the amount of transaction taxes
payable in respect of debit-card sales and use taxes included in the Balance
Sheet and not assumed by the Purchaser), it being understood that (x) the
Closing Reduction Amount shall be recalculated pursuant to the terms hereof and
any increase thereto shall reduce Final Net Assets dollar for dollar to the
extent of such increase and the foregoing credit shall not be applied against
any such reduction, (y) any decrease in the Closing Reduction Amount pursuant to
such recalculation shall increase Final Net Assets dollar for dollar to the
extent of such decrease (but not above the original Closing Reduction Amount
determined at Closing) and (z) any unused portion of such credit shall not be
applied against any other payments to be made by the Seller or the Parent under
any other provision of this Agreement.



     (b) Any payment pursuant to Section 2.04(a) shall be made at a mutually
convenient time and place within 10 days after Final Net Assets has been

certified or official bank check payable in immediately available funds to the
other party or by causing such payments to be credited by wire transfer to such

request from any party to this Agreement, the requested party shall execute,
acknowledge and deliver all such further acts, assurances, deeds, assignments,
transfers, conveyances and other instruments and papers as may be


                                       F-7
<PAGE>   407


reasonably required to sell, assign, transfer, convey and deliver the Assets to
the Purchaser and for the Purchaser to assume the Assumed Liabilities and the
Seller to retain the Excluded Liabilities.



     SECTION 2.07 Employees.  As of the Closing Date, the Purchaser shall hire
(or make offers to hire) all or substantially all of the Seller's employees as
employees of the Purchaser (the "Transferred Employees"). The Purchaser shall
take all such reasonable actions as are necessary to allow the Transferred

to participate in the benefit programs of the Purchaser, and shall use
reasonable efforts to ensure that such benefit plans are substantially similar

Accrued Payphone Compensation.  In addition to the payment of the Purchase
Price, the Purchaser shall, subject to the provisions hereof, assume at the
Closing the Assumed Liabilities. Notwithstanding any provision in this Agreement
or any other writing to the contrary, the Purchaser is assuming only the Assumed
Liabilities and is not assuming the Excluded Liabilities including any other
liability or obligation of Seller (or any predecessor of Seller or any prior
owner of all or part of its businesses and assets) of whatever nature, whether
presently in existence or arising hereafter. All such other liabilities and
obligations shall be retained by and remain obligations and liabilities of
Seller. The parties hereto acknowledge and agree that any Assumed Liabilities
constituting accrued taxes payable and accrued Payphone Compensation shall
remain primarily obligations of the Seller subject to reimbursement, or payment
on the Seller's behalf, by the Purchaser upon its receipt from the Seller of
evidence reasonably satisfactory to the Purchaser that such amounts are required
to be paid (i.e., the Purchaser shall not, without limitation, be required to
file any tax returns or be named a party to any litigation or other
proceedings).



     SECTION 3.02 Bill of Sale.  On the Closing Date, the Purchaser shall
execute and deliver to the Seller the Bill of Sale.

or, to the best knowledge of the Company and the Parent, threatened against the
Company or the Parent challenging the validity or propriety of the transactions

or arrangement serving as a source of funding any benefits payable under any
Company Employee Benefit Plan, and (d) the most recently issued financial
statement and actuarial report, if any, for each Company Employee Benefit Plan.
No "prohibited transactions" (as such term is defined in Section 4975 of the
Code, or in Part 4 of Subtitle B of Title I of ERISA) have occurred with respect
to any Company Employee Benefit Plan that could result in the imposition of
taxes or penalties that, in the aggregate, would have a Company Material Adverse
Effect. With respect to each of the Company Employee Benefit Plans that is
intended to qualify for favorable income tax treatment under Section 401(a) of
the Code,

                                      F-13

(i) the Internal Revenue Service ("IRS") has issued a favorable determination
letter with respect to such plan; (ii) except as set forth on Schedule 5.11, the
Company has furnished the Purchaser with a copy of the determination letter most
recently issued by the IRS with respect to such plan and the application filed
with the IRS for such determination letter; and (iii) to the best knowledge of
the Company, no event has occurred from the date of each such favorable
determination letter that would adversely affect the tax-qualified status of the
plan in question. Each Company Employee Benefit Plan has been administered in
compliance with the applicable requirements of ERISA and the Code, and in
compliance with all other applicable provisions of law, except for such
noncompliance, if any, that, in the aggregate, would not have a Company Material
Adverse Effect. With respect to each Company Employee Benefit Plan, neither the
Company nor any Subsidiary has incurred liabilities which, in the aggregate,
could have a Company Material Adverse Effect as a result of the violation of or
the failure to comply with any applicable provision of ERISA, the Code, any
other applicable provision of law, or any provision of such plan. None of the
Company Employee Benefit Plans which is an "employee pension benefit plan", as
that term is defined in Section 3(2) of ERISA (a "Company Employee Pension
Benefit Plan"), has incurred an "accumulated funding deficiency," within the
meaning of Section 3(2) of ERISA or Section 412 of the Code. Neither the Company
nor any Subsidiary has failed to make any contribution to, or to make any
payment under, any Company Employee Benefit Plan that it was required to make
pursuant to the terms of the plan or pursuant to applicable law in any amount
which, in the aggregate, could have a Company Material Adverse Effect. To the
best knowledge of the Company, no "reportable events," with respect to which a
notice must be filed with the Pension Benefit Guaranty Corporation ("PBGC"), has
occurred with respect to any Company Employee Pension Benefit Plan subject to
Title IV of the ERISA. No proceedings by the PBGC to terminate an y Company
Employee Pension Benefit Plan pursuant to Subtitle C of Title IV of ERISA have
to the best of the Company's knowledge, been instituted or threatened. Except
for any liabilities in an amount which, in the aggregate, would not have a
Company Material Adverse Effect, neither the Company nor any Subsidiary (1) has
incurred any liability to the PBGC in connection with any Company Employee
Pension Benefit Plan, including any liability under Section 4069 of ERISA and
any penalty imposed under Section 4071 of ERISA, (2) has terminated any Company
Employee Pension Benefit Plan, or ceased operations at any facility or withdrawn
from any Company Employee Pension Benefit Plan, in a manner that could subject
it to liability or any liens under Section 4062, 4063, 4064 or 4068 of ERISA or
(3) has any knowledge as to the existence of any state of facts, or as to the
occurrence of any transactions, that might reasonably be anticipated to result
in any liability of the Company or any Subsidiary to the PBGC under any other
provision of Title IV of ERISA. There is no pending or, to the best knowledge of
the Company, threatened legal action, proceeding or investigation against or
involving any Company Employee Benefit Plan which could result in liabilities to
the Plan, the Company or any Subsidiary. Except as disclosed on Schedule 5.11,
the present value of accrued benefits of each Company Employee Benefit Plan that
is a defined benefit plan as defined in Section 3(35) of ERISA does not exceed
the value of the assets of such plan available to pay such benefits by an amount
that, in the aggregate for all such plans, could have a Company Material Adverse
Effect. All representations made by the Company in this Section 5.11 are
likewise true with respect to each Subsidiary.



     SECTION 5.12 Environmental Matters.  "Company Real Properties" shall mean
all real property now or previously owned, operated or leased by the Company,
any Subsidiary or any predecessor-in-interest. Except as set forth on Schedule
5.12: (i) the Company, each of the Subsidiaries, and to the best of the
Company's knowledge, each of the Company Real Properties is in compliance with,
and has no liability under any federal, state, or local law, statute, rule or
regulation, or the common law governing or relating to the environment or to
occupational health and safety ("Environmental Law"), (ii) none of the Company,
any Subsidiary or any of the Company Real Properties has been alleged in writing
by any governmental agency or third party to be in violation of, to be liable
under, or to be subject to any administrative or judicial proceeding pursuant
to, any Environmental Law, and (iii) there are no facts or circumstances which
could reasonably form the basis for the assertion of any claims against the
Company or any Subsidiary relating to environmental matters, except, in any such
case, where the failure to comply or such liability could not be reasonably
expected to have a Company Material Adverse Effect.

<PAGE>   424


Purchaser and its affiliates, officers, directors, employees, agents and

entitlement to indemnification hereunder except to the extent that the
indemnifying party shall have been actually prejudiced as a result of such
failure. The indemnified party shall take all reasonable or necessary steps to
cooperate in the defense of such Claims, including retaining and providing to
the indemnifying party all documents, records and other information that may be
relevant to such Claims and making employees available to the extent reasonably
requested to fully cooperate in the resolution or defense of such Claims and
provide any additional information (including explanations and interpretations

specific performance or other equitable relief to prevent breaches of the terms
of this Agreement and to enforce specifically such terms in addition to any
other remedies to which the indemnified party may be entitled, at law or in
equity. Notwithstanding the foregoing, each of the Parent and the Seller hereby
agrees that in the event that the Seller fails or refuses to consummate the
transactions contemplated by this Agreement with the Purchaser for any reason
(other than (i) the failure, after good faith efforts, to obtain necessary
regulatory approval for the transactions contemplated hereby, (ii) the failure,
after good faith efforts by the Board of the Parent, of a majority of the
Parent's shareholders entitled to vote to approve the transactions contemplated
hereby (provided that if within 12 months of such failure to approve the Asset
Sale, the Assets are directly or indirectly sold to a third party other than the
Purchaser, the exclusion contained in this clause (ii) shall not apply), (iii)
the Purchaser's breach of the material terms and conditions of this Agreement,
or (iv) the mutual written consent of the Purchaser, Seller and Parent), the
Seller shall promptly upon demand pay to the Purchaser $5,850,000 in cash as
liquidated damages (the "Liquidated Damages Amount") by wire transfer to a bank
account designated by the Purchaser to the Parent. Each of the Parent and the
Seller hereby acknowledges that the Liquidated Damages Amount is reasonable and
not punitive in nature. The Purchaser acknowledges and agrees that the payment
of the Liquidated Damages Amount shall be the exclusive remedy of the Purchaser
for such failure or refusal by the Seller referred to in this Section 10.05;
provided that the payment of the Liquidated Damages Amount shall not be the
Purchaser's exclusive remedy in respect of the foregoing in the event (i) the
Parent or the Seller willfully breaches the terms of this Agreement or (ii) the
Parent or the Seller fails to pay the Liquidated Damages Amount within 10
Business Days of the Purchaser's demand therefor absent a good faith, reasonable
basis dispute between the parties as to the legitimacy of the Purchaser's
demand.



     SECTION 10.07 Escrow Amount.  The Purchaser shall be entitled to satisfy
any indemnifiable claims or Liquidated Damages Amount under this Article X out
of the Escrow Amount without limiting any of its other rights or remedies
against the Seller and the Parent hereunder in excess of the Escrow Amount.

     SECTION 11.02 Financial Records and Product History Files.  (a) If at any
time it is necessary that a party be furnished with additional information,
documents or records relating to the Assets or the Business in order properly to
prepare or support any Action (other than an Action in which the parties hereto
are opposed in interest) or its Company Tax returns or other documents or
reports required to be filed with governmental authorities or any securities
exchanges or otherwise for any reasonably legitimate purpose, and such
information, documents or records are in the possession or control of another
party, such


                                      F-26
<PAGE>   426


other party agrees to use all reasonable efforts (at the expense of the
requesting party) to furnish or make available such information, documents or
records (or copies thereof) and personnel; and



     (b) Each party to this Agreement hereby agrees that it shall cooperate with
the other by executing and/or filing or causing to be executed and/or filed any
required documents and by making available to the other, without limitation, all
work papers, records and notes of any kind, at all reasonable times, for the
purpose of allowing the appropriate party to complete Tax returns, respond to
audits, obtain refunds, make any determination required under this Agreement,
verify issues and negotiate settlements with Tax authorities or defend or
prosecute Tax claims. In the case of Income Taxes relating to the Business, the

provided, however, that the Purchaser shall remain jointly and severally liable

                                  May 25, 2000



To the Board of Directors of


Star Telecommunications, Inc.


223 E. De La Guerra Street


Santa Barbara, California 93101



Gentlemen:



     We understand that Star Telecommunications, Inc. (the "Star") and PT-1
Communications, Inc., a wholly-owned subsidiary of Star ("PT-1"), propose to
enter into a Asset Purchase Agreement (the "Asset Purchase Agreement") with
Counsel Communications LLC ("Counsel"), pursuant to which PT-1 will sell certain
of its assets to Counsel for an aggregate purchase price of $150 million (the
"Transaction"). In addition, Counsel will assume certain of the liabilities of
PT-1. Consummation of the Transaction is subject to, among other things, the
approval of the shareholders of Star. The terms of the Transaction are more
fully described in the Asset Purchase Agreement.



     In connection with your review and analysis of the Transaction, you have
requested our opinion, as investment bankers, as to the fairness, from a
financial point of view, of the consideration to be paid by Counsel to Star in
the Transaction (including the assumption of liabilities) to the shareholders of
Star.



     Kaufman Bros., L.P., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of securities, private placements of public and private companies
and valuations for corporate and other purposes.



     In conducting our analysis and arriving at our opinion as expressed herein,
we have reviewed, among other things, the following:



     - a draft of the Asset Purchase Agreement, dated May 23, 2000, by and among
       Star, PT-1 and Counsel;



     - a draft of the Joint Proxy Statement/Prospectus, dated May   , 2000,
       relating to the Transaction;



     - certain documents and reports filed by Star and Counsel with the
       Securities and Exchange Commission;



     - certain internal information and documents relating to PT-1 provided to
       us by Star's and PT-1's respective managements, including historical
       financial information and financial forecasts;



     - certain publicly available information concerning certain other companies
       engaged in businesses which we believe to be reasonably comparable to
       PT-1; and



     - information concerning certain other business transactions which we
       believe to be reasonably comparable to the Transaction.



     We have also discussed with certain officers and employees of Star and PT-1
the business and operations, assets, present condition and future prospects of
PT-1, and performed such analyses as we deemed appropriate.



     We visited the PT-1 facility in Flushing, New York, but have not made,
obtained or been provided with any independent evaluation or appraisal of the
properties and facilities or of any of the assets or liabilities of PT-1
(contingent or otherwise). We have assumed and relied upon the accuracy and
completeness of the financial and other information used by us in arriving at
our opinion, and upon the assurances of the managements of Star and PT-1 that
they are not aware of any information that would make the information provided
to us incomplete or misleading, and have not attempted to independently


                                       G-1
<PAGE>   431


verify such information. With respect to financial forecasts, we were advised by
the management of Star, and we assumed without independent investigation, that
they were reasonably prepared and reflected, as of the times they were delivered
to us, the best currently available estimates and judgment as to the expected
future financial performance of PT-1. We have also assumed, with your permission
and without independent investigation, that:



     - The Transaction will be consummated in accordance with the terms set
       forth in the draft of the Asset Purchase Agreement, dated May 23, 2000,
       without any amendment thereto and without any waiver by any of the
       parties of any of the conditions to their respective obligations; and



     - All regulatory and other approvals and third party consents required for
       consummation of the Transaction will be obtained without material cost to
       Star or PT-1.



     Our opinion is necessarily based upon financial, economic, market and other
conditions as they exist, and the information available to us, as of the date
hereof. We disclaim any undertakings or obligation to advise any person of any
change in any fact or matter affecting this opinion which may come or be brought
to our attention after the date hereof. Although we evaluated the consideration
to be paid by Counsel to PT-1 in the Transaction from a financial point of view,
Kaufman was not asked to and did not recommend the specific consideration
payable in the Transaction, which was determined through negotiations between
Star and Counsel.



     In the ordinary course of our business, we may hold and actively trade
securities of Star for our own account and for the accounts of our customers
and, accordingly, may at any time hold a long or short position in such
securities.



     Our opinion does not constitute a recommendation as to any action the Board
of Directors or any shareholder of Star should take in connection with the
Transaction or any aspect thereof and is not a recommendation to any person on
how such person should vote in his or her consideration of the Transaction. Our
opinion relates solely to the fairness, as of the date hereof, from a financial
point of view, of the consideration to be paid by Counsel to PT-1 in the
Transaction to the shareholders of Star. We express no opinion herein as to the
structure, terms or effect of any other aspect of the Transaction, the merits of
the underlying decision of Star or PT-1 to enter into the Transaction or any
other transactions or business strategies discussed by the Boards of Directors
of Star or PT-1 as alternatives to the Transaction. Without limiting the
generality of the foregoing, we express no opinion as to any aspect of the
proposed merger among Star, World Access, Inc. and STI Merger Co.



     This opinion has been prepared at the request of, and for the information
of, the Board of Directors of Star solely for its use in evaluating the
fairness, from a financial point of view, of the consideration to be paid by
Counsel to PT-1 in the Transaction to the shareholders of Star. It may not be
used for any other purpose, published, reproduced, summarized, described or
referred to or given to any other person or otherwise made public without our
prior written consent.



     Based upon and subject to the foregoing, it is our opinion, as investment
bankers, that, as of the date hereof, the consideration to be paid by Counsel to
PT-1 in the Transaction (including the assumption of liabilities) is fair, from
a financial point of view, to the shareholders of Star.



                                          Very truly yours,



                                          KAUFMAN BROS., L.P.

                                                                         ANNEX H


              SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW

     sec. 262. Appraisal rights.

     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec. 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to
sec. 251(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or
sec. 264 of this title:

          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a.  Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

             b.  Shares of stock of any other corporation, or depository
        receipts in respect thereof, which shares of stock (or depository
        receipts in respect thereof) or depository receipts at the effective
        date of the merger or consolidation will be either listed on a national
        securities exchange or designated as a national market system security
        on an interdealer quotation system by the National Association of
        Securities Dealers, Inc. or held of record by more than 2,000 holders;

             c.  Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

             d.  Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

                                       H-1
<PAGE>   433

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of such
     stockholder's shares shall deliver to the corporation, before the taking of
     the vote on the merger or consolidation, a written demand for appraisal of
     such stockholder's shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of such stockholder's
     shares. A proxy or vote against the merger or consolidation shall not
     constitute such a demand. A stockholder electing to take such action must
     do so by a separate written demand as herein provided. Within 10 days after
     the effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each constituent
     corporation who has complied with this subsection and has not voted in
     favor of or consented to the merger or consolidation of the date that the
     merger or consolidation has become effective; or

          (2) If the merger or consolidation was approved pursuant to sec. 228
     or sec. 253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated
                                       H-2
<PAGE>   434

     therein. For purposes of determining the stockholders entitled to receive
     either notice, each constituent corporation may fix, in advance, a record
     date that shall be not more than 10 days prior to the date the notice is
     given, provided, that if the notice is given on or after the effective date
     of the merger or consolidation, the record date shall be such effective
     date. If no record date is fixed and the notice is given prior to the
     effective date, the record date shall be the close of business on the day
     next preceding the day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has
                                       H-3
<PAGE>   435

submitted such stockholder's certificates of stock to the Register in Chancery,
if such is required, may participate fully in all proceedings until it is
finally determined that such stockholder is not entitled to appraisal rights
under this section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

      SECTIONS 1300 THROUGH 1312 OF THE CALIFORNIA GENERAL CORPORATION LAW

     Section 1300.  Shareholder in short-form merger; Purchase at fair market
value; "Dissenting shares"; "Dissenting shareholder"

     (a) If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation in a short-form merger may, by complying with this chapter, require
the corporation in which the shareholder holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision (b). The fair market value shall be determined
as of the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split, or share dividend which becomes effective thereafter.

     (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:

          (1) Which were not immediately prior to the reorganization or
     short-form merger either (A) listed on any national securities exchange
     certified by the Commissioner of Corporations under subdivision (o) of
     Section 25100 or (B) listed on the National Market System of the NASDAQ
     Stock Market, and the notice of meeting of shareholders to act upon the
     reorganization summarizes this section and Sections 1301, 1302, 1303 and
     1304; provided, however, that this provision does not apply to any shares
     with respect to which there exists any restriction on transfer imposed by
     the corporation or by any law or regulation; and provided, further, that
     this provision does not apply to any class of shares described in
     subparagraph (A) or (B) if demands for payment are filed with respect to 5
     percent or more of the outstanding shares of that class.

          (2) Which were outstanding on the date for the determination of
     shareholders entitled to vote on the reorganization and (A) were not voted
     in favor of the reorganization or, (B) if described in subparagraph (A) or
     (B) of paragraph (1) (without regard to the provisos in that paragraph),
     were voted against the reorganization, or which were held of record on the
     effective date of a short-form merger; provided, however, that subparagraph
     (A) rather than subparagraph (B) of this paragraph applies in any case
     where the approval required by Section 1201 is sought by written consent
     rather than at a meeting.

          (3) Which the dissenting shareholder has demanded that the corporation
     purchase at their fair market value, in accordance with Section 1301.

          (4) Which the dissenting shareholder has submitted for endorsement, in
     accordance with Section 1302.

     (c) As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.

     Section 1301.  Notice to holder of dissenting shares of reorganization
approval; Demand for purchase of shares; Contents of demand

     (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a brief description of the procedure to be followed if
the shareholder desires to exercise the shareholder's

                                       I-1
<PAGE>   437

right under such sections. The statement of price constitutes an offer by the
corporation to purchase at the price stated any dissenting shares as defined in
subdivision (b) of Section 1300, unless they lose their status as dissenting
shares under Section 1309.

     (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.

     (c) The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

     Section 1302.  Stamping or endorsing dissenting shares

     Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.

     Section 1303.  Dissenting shareholder entitled to agreed price with
interest thereon; When price to be paid

     (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

     (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.

     Section 1304.  Action by dissenters to determine whether shares are
dissenting shares or fair market value of dissenting shares or both; Joinder of
shareholders; Consolidation of actions; Determination of issues; Appointment of
appraisers

     (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder fail to agree upon the fair market value of the
shares, then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision

                                       I-2
<PAGE>   438

(i) of Section 1110 was mailed to the shareholder, but not thereafter, may file
a complaint in the superior court of the proper county praying the court to
determine whether the shares are dissenting shares or the fair market value of
the dissenting shares or both or may intervene in any action pending on such a
complaint.

     (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.

     (c) On the trial of the action, the court shall determine the issues. If
the status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

     Section 1305.  Duty and report of appraisers; Court's confirmation of
report; Determination of fair market value by court; Judgment, and payment;
Appeal; Costs of action

     (a) If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share. Within the time fixed by
the court, the appraisers, or a majority of them, shall make and file a report
in the office of the clerk of the court. Thereupon, on the motion of any party,
the report shall be submitted to the court and considered on such evidence as
the court considers relevant. If the court finds the report reasonable, the
court may confirm it.

     (b) If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

     (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.

     (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

     (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

     Section 1306.   Prevention of payment to holders of dissenting shares of
fair market
value; Effect

     To the extent that the provisions of Chapter 5 prevent the payment to any
holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.

     Section 1307.  Disposition of dividends upon dissenting shares

     Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against the total amount to be paid by the corporation
therefor.

                                       I-3
<PAGE>   439

     Section 1308.  Rights and privileges of dissenting shares; Withdrawal of
demand for payment

     Except as expressly limited in this chapter, holders of dissenting shares
continue to have all the rights and privileges incident to their shares, until
the fair market value of their shares is agreed upon or determined. A dissenting
shareholder may not withdraw a demand for payment unless the corporation
consents thereto.

     Section 1309.  When dissenting shares lose their status

     Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to require
the corporation to purchase their shares upon the happening of any of the
following:

          (a) The corporation abandons the reorganization. Upon abandonment of
     the reorganization, the corporation shall pay on demand to any dissenting
     shareholder who has initiated proceedings in good faith under this chapter
     all necessary expenses incurred in such proceedings and reasonable
     attorneys' fees.

          (b) The shares are transferred prior to their submission for
     endorsement in accordance with Section 1302 or are surrendered for
     conversion into shares of another class in accordance with the articles.

          (c) The dissenting shareholder and the corporation do not agree upon
     the status of the shares as dissenting shares or upon the purchase price of
     the shares, and neither files a complaint or intervenes in a pending action
     as provided in Section 1304, within six months after the date on which
     notice of the approval by the outstanding shares or notice pursuant to
     subdivision (i) of Section 1110 was mailed to the shareholder.

          (d) The dissenting shareholder, with the consent of the corporation,
     withdraws the shareholder's demand for purchase of the dissenting shares.

     Section 1310.  Suspension of proceedings for compensation or valuation
pending
litigation

     If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings under
Sections 1304 and 1305 shall be suspended until final determination of such
litigation.

     Section 1311.  Shares to which chapter inapplicable

     This chapter, except Section 1312, does not apply to classes of shares
whose terms and provisions specifically set forth the amount to be paid in
respect to such shares in the event of a reorganization or merger.

     Section 1312.  Attack on validity of reorganization or short-form merger;
Rights of shareholders; Burden of proof

     (a) No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

     (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such
                                       I-4
<PAGE>   440

shareholder's shares pursuant to this chapter; but if the shareholder institutes
any action to attack the validity of the reorganization or short-form merger or
to have the reorganization or short-form merger set aside or rescinded, the
shareholder shall not thereafter have any right to demand payment of cash for
the shareholder's shares pursuant to this chapter. The court in any action
attacking the validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded shall not restrain or
enjoin the consummation of the transaction except upon 10 days' prior notice to
the corporation and upon a determination by the court that clearly no other
remedy will adequately protect the complaining shareholder or the class of
shareholders of which such shareholder is a member.

     (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS


     Section 102 of the General Corporation Law of the State of Delaware
("DGCL") allows a corporation to eliminate or limit the personal liability of
directors of a corporation to the corporation or to any of its security holders
for monetary damages for a breach of fiduciary duty as a director, except (i)
for breach of the director's duty or 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.

     Articles X and XI of the World Access, Inc. amended certificate of
incorporation provide for indemnification of directors, officers and employees
to the fullest extent permissible under the DGCL.

     Officers and directors of World Access are presently covered by insurance
which (with certain exceptions and with certain limitations) indemnifies them
against any losses or liabilities arising from any alleged "wrongful act"
including any alleged breach of duty, neglect, error, misstatement, misleading
statement, omissions or other act done or wrongfully attempted. The cost of such
insurance is borne by World Access as permitted by the DGCL.

     World Access has entered into separate indemnification agreements with its
directors and non-director officers at the level of Vice President and above.
These indemnification agreements provide as follows:

     - there is a rebuttable presumption that the director or officer has met
       the applicable standard of conduct required for indemnification;

     - World Access will advance litigation expenses to a director or officer at
       his request provided that he undertakes to repay the amount advanced if
       it is ultimately determined that he is not entitled to indemnification
       for such expenses;

     - World Access will indemnify a director or officer for amounts paid in
       settlement of a derivative suit;

     - in the event of a determination by the disinterested members of the board
       of directors or independent counsel that a director or officer did not
       meet the standard of conduct required for indemnification, the director
       or officer may contest this determination by petitioning a court or
       commencing any arbitration proceeding conducted by a single arbitrator
       pursuant to the rules of the American Arbitration Association to make an
       independent determination of whether such director or officer is entitled
       to indemnification under his indemnification agreement; and

     - World Access will reimburse a director or officer for expenses incurred
       enforcing his rights under his indemnification agreement.

     (B)  Financial Statement Schedules.  The financial statement schedules that
are required by Regulation S-X are incorporated herein by reference to our
Annual Report on Form 10-K for the year ended December 31, 1999.

ITEM 22.  UNDERTAKINGS


     The undersigned registrant hereby undertakes:



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



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



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


                                      II-6
<PAGE>   447


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



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



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



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



          (4) If the registrant is a foreign private issuer, to file a
     post-effective amendment to the registration statement to include any
     financial statements required by Rule 3-19 of this chapter at the start of
     any delayed offering or throughout a continuous offering. Financial
     statements and information otherwise required by Section 10(a)(3) of the
     Act need not be furnished, provided, that the registrant includes in the
     prospectus, by means of a post-effective amendment, financial statements
     required pursuant to this paragraph (a)(4) and other information necessary
     to ensure that all other information in the prospectus is at least as
     current as the date of those financial statements. Notwithstanding the
     foregoing, with respect to registration statements on Form F-3, a
     post-effective amendment need not be filed to include financial statements
     and information required by Section 10(a)(3) of the Act or Rule 3-19 of
     this chapter if such financial statements and information are contained in
     periodic reports filed with or furnished to the Commission by the
     registrant pursuant to Section 13 or Section 15(d) of the Securities
     Exchange Act of 1934 that are incorporated by reference in the Form F-3.



          (5) Insofar as the 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
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Act and is, therefore, unenforceable. In the
     event that 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 Act and will be governed by the final
     adjudication of such issue.



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



          (7) 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.
