To the Stockholders of STAR Telecommunications, Inc.:

     We have entered into a merger agreement with World Access, Inc. The STAR
merger agreement provides for a merger that would result in STAR becoming a
wholly-owned subsidiary of World Access. As a stockholder of STAR, you would
become a stockholder of World Access as a result of the STAR merger. The STAR
merger agreement also provides for the sale to a third party of PT-1
Communications, Inc., our wholly-owned subsidiary. As a result of the STAR
merger, each outstanding share of STAR common stock will be converted into the
right to receive, at the election of World Access, (a) 0.3905 shares of World
Access common stock, subject to adjustment as described in the accompanying
joint proxy statement/prospectus, or (b) a combination of shares of World Access
common stock and cash.

     As further described in the joint proxy statement/prospectus, we are also
seeking stockholder approval for the PT-1 sale. We have entered into a letter of
intent with a third party, PT-1 acquiror, for the PT-1 sale and we anticipate
that we will enter into a definitive agreement with PT-1 acquiror. This joint
proxy statement/prospectus describes the PT-1 letter of intent in detail. We are
seeking stockholder approval to proceed with the PT-1 sale to PT-1 acquiror, or
in the event that we do not reach a definitive agreement with PT-1 acquiror, to
such other buyer and on such other terms as our board of directors shall
subsequently approve, subject to the minimum requirements set forth in the joint
proxy statement/prospectus, including our receipt of a sales price of at least
$       , obtaining the opinion of our financial advisor in connection with the
sale and approval by our board of directors of a definitive sale agreement
containing terms that our board of directors determines to be in the best
interests of STAR. Except as requested in the joint proxy statement/prospectus,
we will not solicit any further stockholder vote for the PT-1 sale. Accordingly,
you will not have the opportunity to vote on a definitive PT-1 sale agreement.

     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 May
22, 2000 was $11 9/16 per share.

     We cannot complete the STAR merger or the PT-1 sale without the approval of
our stockholders. We have scheduled a special meeting on           ,           ,
2000 at          , local time, at           , to vote on these transactions. A
joint proxy statement/prospectus accompanies this letter and provides detailed
information about the special meeting, the STAR merger and the PT-1 sale. We
urge you to read the joint proxy statement/prospectus document carefully.

     Your board of directors recommends that you vote to approve the STAR merger
agreement and the PT-1 sale. Please use this opportunity to take part in the
affairs of STAR by voting on these important matters. Whether or not you plan to
attend the meeting, please complete, sign, date and return the accompanying
proxy in the enclosed envelope. Returning the proxy will not deprive you of your
right to attend the special meeting and vote in person. Your vote is very
important.

                                          Sincerely,

                                          /s/ Mary A. Casey

                         STAR TELECOMMUNICATIONS, INC.
                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

                         TO BE HELD ON          , 2000

To the Stockholders of STAR Telecommunications, Inc.:

     We have agreed, subject to your approval, to merge STAR with a subsidiary
of World Access, Inc. We also have agreed with World Access to sell PT-1
Communications, Inc., our wholly-owned subsidiary, to a third party. The PT-1
sale also requires your approval. If the STAR merger agreement is approved by
our stockholders and the STAR merger is completed, each outstanding share of
STAR common stock will be converted into the right to receive, at the election
of World Access, (a) 0.3905 shares of World Access common stock, subject to
adjustment as described in the joint proxy statement/prospectus, or (b) a
combination of shares of World Access common stock and cash. If STAR does not
sell PT-1 prior to the completion of the STAR merger, or if STAR does not
receive net cash proceeds of at least $150.0 million from the PT-1 sale, then
World Access does not have to complete the STAR merger.

     We will hold a special meeting of stockholders on           ,           ,
2000 at           , local time, at           , for the following purposes:

          1. Proposal 1. To approve the Agreement and Plan of Merger, dated as
     of February 11, 2000, among World Access, STI Merger Co. and STAR, which
     will result in STAR becoming a wholly-owned subsidiary of World Access;

          2. Proposal 2. To consider a resolution authorizing the PT-1 sale
     subject to the minimum requirements set forth in the accompanying joint
     proxy statement/prospectus, including STAR's receipt of a sales price of at
     least $       , obtaining the opinion of STAR's financial advisor as to the

                SUMMARY OF THE JOINT PROXY STATEMENT/PROSPECTUS

     This joint proxy statement/prospectus pertains to the merger of STI Merger
Co., a wholly-owned subsidiary of World Access, and STAR Telecommunications,
Inc., the merger of WORLDxCHANGE Communications, Inc. f/k/a CTI Merger Co., a
wholly-owned subsidiary of World Access, and Communication TeleSystems
International d/b/a WORLDxCHANGE Communications, as well as the sale by STAR of
its wholly-owned subsidiary, PT-1 Communications, Inc., and is being sent to the
stockholders of World Access, STAR and WORLDxCHANGE. The joint proxy
statement/prospectus also pertains to two proposals regarding amendments to the
World Access Amended Certificate of Incorporation, a proposal regarding an
amendment to the World Access Directors' Warrant Incentive Plan and the election
of the nominees named herein as World Access directors, that only the World
Access stockholders will consider and vote upon. World Access is soliciting
proxies for its special meeting in lieu of an annual meeting and is asking its
stockholders to consider and vote upon all of the proposals described in this
joint proxy statement/prospectus, other than the PT-1 sale. STAR is soliciting
proxies for its special meeting and is asking its stockholders to consider and
vote upon the proposed merger between World Access and STAR and the sale by STAR
of PT-1 described in this joint proxy statement/prospectus. WORLDxCHANGE is not
soliciting proxies or consents from its shareholders. Rather, World Access is
providing this joint proxy statement/prospectus to the WORLDxCHANGE shareholders
in connection with the issuance of World Access common stock to such
shareholders in the proposed merger between World Access and WORLDxCHANGE.
Throughout this joint proxy statement/prospectus, "we" and "us" mean World
Access and its subsidiaries after giving effect to the STAR merger and the
WORLDxCHANGE merger.

                             QUESTIONS AND ANSWERS
                     FOR WORLD ACCESS AND STAR STOCKHOLDERS

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.

     After the STAR merger, assuming completion of the proposed combination of
     World Access with WORLDxCHANGE, which is discussed further below, and
     assuming that World Access elects to use its stock as the sole
     consideration in the STAR merger to the extent possible, the stockholders
     of World Access will own approximately 63.0%, the former stockholders of
     STAR will own approximately 17.0%, and the former shareholders of
     WORLDxCHANGE will own approximately 20.0% in voting power of the combined
     companies. If the STAR merger is completed but the WORLDxCHANGE merger is
     not completed, the former stockholders of STAR will own approximately 22.0%
     of the combined companies.

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. 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, 0.3905 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. The exact exchange ratio
     is determined by solving for "X" in the following equation:

                                     X = 7.81 + Z

     "Z" equals the net cash proceeds in excess of $150.0 million received by
     STAR at the time of the completion of the sale of PT-1, divided by
     62,856,702 (the number of issued and outstanding shares

                                        1
<PAGE>   15

     of STAR common stock, plus the number of shares underlying outstanding STAR
     stock options and warrants as of February 11, 2000).

     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-day period ending at the close of
     trading on the date of the completion of the STAR merger.

     EXAMPLE:  Assume that (i) you, a STAR stockholder, own 100 shares of STAR
     common stock, (ii) prior to the completion of the STAR merger, STAR sells
     PT-1 for net cash proceeds of $200.0 million, and (iii) the average closing
     sale price of World Access common stock over a ten-day period ending at the
     close of trading on the date of the completion of the STAR merger is
     $25.00. In this case, the exchange ratio would be increased to 0.4305
     ((7.81 + 0.8)/20). Therefore, you would be entitled to receive 43 shares of
     World Access common stock (100 x 0.4305) and a check for $1.25.

     Instead of only issuing shares of World Access common stock to the STAR
     stockholders in the STAR merger, World Access may issue, for each share of
     STAR common stock, a number of shares of World Access common stock equal to
     60% of the exchange ratio and an amount in cash equal to 40% of the sum of
     $7.81 plus "Z." As is the case with the first form of consideration, 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-day period ending at the close of trading on
     the date of the completion of the STAR merger.

     EXAMPLE:  Using the same assumptions described above and further assuming
     that World Access elects to issue shares of World Access common stock and
     cash upon completion of the STAR merger, you would be entitled to receive
     25 shares of World Access common stock (0.2583 x 100) and a check for
     $365.15. This check would represent cash in lieu of fractional shares (0.83
     x $25) and the cash portion of the merger consideration ((40% of 7.81 +
     0.8) x 100).

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 does not receive net cash proceeds of at least $150.0 million from
     the PT-1 sale, then World Access does not have to complete the STAR merger.
     STAR has entered into a letter of intent with PT-1 acquiror for the PT-1
     sale and STAR anticipates that it will enter into a definitive agreement
     with PT-1 acquiror. In the event that STAR does not reach a definitive
     agreement with PT-1 acquiror, STAR will sell PT-1 to such other buyer and
     on such other terms as the STAR board of directors shall subsequently
     approve, subject to the minimum requirements set forth in this joint proxy
     statement/prospectus, including STAR's receipt of a sales price of at least
     $       , obtaining the opinion of STAR's financial advisor in connection
     with the sale and approval by the STAR board of directors of a definitive
     sale agreement containing terms that the STAR board of directors determines
     to be in the best interests of STAR.

Q:   WHAT HAPPENS IF THE STAR STOCKHOLDERS APPROVE THE PT-1 SALE FOR A SALES
     PRICE OF AT LEAST $          ?

A:   If the STAR stockholders approve the PT-1 sale for a sales price of at
     least $          , the minimum requirements set forth in this joint proxy
     statement/prospectus have been met and negotiations have been successfully
     completed with PT-1 acquiror, STAR will sell PT-1 to PT-1 acquiror. In the
     event that STAR is unable to negotiate a definitive agreement with PT-1
     acquiror, STAR will attempt to sell PT-1 for a sales price of at least
     $          to such other buyer and on such other terms as the STAR board of
     directors shall subsequently approve. The consummation of any PT-1 sale
     would be subject to STAR's receipt of a sales price of at least
     $          , obtaining the opinion of STAR's financial advisor in
     connection with the sale and approval by the STAR board of directors of a

                                        2
<PAGE>   16

     definitive sale agreement containing terms that the STAR board of directors
     determines to be in the best interests of STAR. Except as requested in the
     accompanying joint proxy statement/prospectus, STAR will not solicit any
     further stockholder vote for the PT-1 sale. Accordingly, STAR stockholders
     will not have the opportunity to vote on a definitive PT-1 sale agreement.

Q:   WHAT IS THE WORLDXCHANGE MERGER?

A:   World Access has also agreed to a merger between another of its
     wholly-owned subsidiaries and WORLDxCHANGE. The WORLDxCHANGE merger is
     described in this joint proxy statement/ prospectus. 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.

     You should be aware that if the WORLDxCHANGE merger is completed, the
     business and operations of WORLDxCHANGE will be vested in WORLDxCHANGE
     Communications, Inc., which will be a wholly-owned subsidiary of World
     Access, and WORLDxCHANGE shareholders will become stockholders of World
     Access.

     This joint proxy statement/prospectus is also being sent to shareholders of
     WORLDxCHANGE. 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:   DOES THE BOARD OF DIRECTORS OF WORLD ACCESS RECOMMEND VOTING IN FAVOR OF
     THE STAR MERGER?

A:   Yes. After careful consideration, World Access' board of directors
     recommends that its stockholders vote in favor of the STAR merger agreement
     and the issuance of shares of World Access common stock to the stockholders
     of STAR in the merger.

Q:   DOES THE BOARD OF DIRECTORS OF STAR RECOMMEND VOTING IN FAVOR OF THE STAR
     MERGER AND THE PT-1 SALE?

A:   Yes. After careful consideration, STAR's board of directors recommends that
     its stockholders vote in favor of the STAR merger agreement, the proposed
     STAR merger and the proposed PT-1 sale to PT-1 acquiror or such other
     buyer, subject to the minimum requirements set forth in this joint proxy
     statement/prospectus, including STAR's receipt of a sales price of at least
     $            , obtaining the opinion of STAR's financial advisor as to the
     fairness from a financial point of view of the consideration to be received
     in the sale and approval by the STAR board of directors of a definitive
     sale agreement containing terms that the STAR board of directors determines
     to be in the best interests of STAR.

Q:   ARE THERE RISKS I SHOULD CONSIDER IN DECIDING WHETHER TO VOTE FOR THE STAR
     MERGER AND THE PT-1 SALE?

A:   Yes. In evaluating the STAR merger and the PT-1 sale, you should carefully
     consider the factors discussed in the section entitled "Risk Factors" on
     page 38.

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 may 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 to be voted on at the
     meeting with regard to which you are entitled to vote.

<PAGE>   17

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 voting
     agreements described herein may not revoke the proxies given by them 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 voting or conversion agreements described
     herein may not revoke the proxies given by them 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 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 sale, as quickly as possible. World
     Access and STAR hope to complete the STAR merger, and STAR hopes to
     complete the PT-1 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
     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 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) pursuant to the terms of 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 stock. In order to preserve this right,
     you must follow the procedures discussed on page 83 of this joint proxy
     statement/prospectus. STAR stockholders are not entitled to appraisal
     rights in connection with the PT-1 sale. If you are a World Access
     stockholder, you are not entitled to appraisal rights under Delaware law.

                                QUESTIONS AND ANSWERS
                    FOR WORLD ACCESS AND WORLDXCHANGE STOCKHOLDERS

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, assuming completion of the proposed
     combination of World Access with STAR, which is discussed above, the
     stockholders of World Access will own approximately 63.0%, the former
     shareholders of WORLDxCHANGE will own approximately 20.0%, and the former
     stockholders of STAR will own approximately 17.0% in voting power of the
     combined companies. If the WORLDxCHANGE merger is completed but the STAR
     merger is not completed, the former shareholders of WORLDxCHANGE will own
     approximately 24.0% in voting power of the combined companies.

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.
     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 10-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.

     EXAMPLE:  If you, a WORLDxCHANGE shareholder, own 100 shares of
     WORLDxCHANGE common stock, then after the completion of the WORLDxCHANGE
     merger you will receive 65 shares of World Access common stock (100 x
     0.6583) and a check for $20.75 (0.83 x $25.00).

     additional merger, the STAR merger, and the sale by STAR of its

     does not depend on the completion of the STAR merger or the PT-1 sale, and
     the completion of the STAR merger or the PT-1 sale does not depend on the
     completion of the WORLDxCHANGE merger. Consequently, there are three
     possible combinations that you should consider:

Q.   DOES THE BOARD OF DIRECTORS OF WORLD ACCESS RECOMMEND VOTING IN FAVOR OF

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

     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 121 of this joint proxy
     statement/prospectus. If you are a World Access stockholder, you are not
     entitled to appraisal rights under Delaware law.

                           SUMMARY OF THE STAR MERGER

THE STAR MERGER

     In the STAR merger, STAR will merge with and into a wholly-owned subsidiary
of World Access and, as a result, STAR will become a wholly-owned subsidiary of
World Access.

     The STAR merger agreement is attached to this joint proxy
statement/prospectus as Annex A. World Access and STAR encourage you to read the
STAR merger agreement carefully. The STAR merger agreement is more fully
described on page 86.

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

     - potential cost savings and synergies from financial and operating
       efficiencies and other synergies that would potentially result from
       integrating the systems and operations of both companies;

     - creation of a diversified geographic and product market position for the
       combined companies which could potentially become a leading provider of
       global telecommunications services with a state-of-the-art pan-European
       network;

     - 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.

     There are potential risks to the STAR merger, including:

     - profitability may not be achieved, and World Access and STAR will incur
       significant merger-related expenses;

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

     - market share may decrease, and we may face pricing pressures if we 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 our
       services and products.

     The potential benefits to the STAR merger may not be achieved.

TERMINATION OF THE STAR MERGER AGREEMENT

     The STAR merger agreement may be terminated under limited circumstances at
any time before the completion of the STAR merger. The circumstances, subject to
exceptions and qualifications, include:

     - by mutual written consent of World Access and STAR;

     - by World Access or STAR, in the event of an uncured breach by the other
       party of any of its covenants or agreements in the STAR merger agreement;

     - by World Access or STAR, in the event of an uncured breach by the other
       party of any of its representations or warranties in the STAR merger
       agreement;

     - by World Access or STAR, if the STAR merger is not completed on or before
       September 30, 2000;

     - by World Access or STAR if a final, nonappealable court order prohibiting
       the STAR merger is issued or if a court fails to issue a court order
       which is necessary to complete the STAR merger, and the failure to issue
       the order is final and nonappealable;

     - by World Access or STAR, if the stockholders of World Access or STAR fail
       to adopt the STAR merger agreement by the requisite vote at meetings duly
       called;

     - by World Access, if the STAR board of directors (i) withdraws or modifies
       its recommendation that the STAR stockholders approve and adopt the STAR
       merger agreement and the STAR merger or (ii) approves or recommends an
       alternative proposal which the STAR board of directors concludes would
       result in a more favorable transaction, from a financial point of view,
       to the STAR stockholders than the STAR merger;

     - by STAR, at any time prior to the STAR stockholders' vote upon three
       business days' prior notice to World Access, if the STAR board of
       directors determines that an alternative proposal to acquire a majority
       of the stock or assets of STAR or in which the continuing STAR directors
       would not constitute a majority of the directors of the surviving entity
       would result in a more favorable transaction, from a financial point of
       view, to the STAR stockholders than the STAR merger;

     - by World Access, if either STAR or any of its material subsidiaries is
       the subject of (i) a voluntary or involuntary bankruptcy proceeding, (ii)
       the appointment of a liquidator, receiver or similar official or (iii)
       liquidation proceedings or the winding up of affairs; or

     - by World Access if there is an event of default under an anticipated
       credit agreement between World Access and STAR.

TERMINATION FEE

     If the STAR merger agreement is terminated for certain reasons, STAR will
be required to pay World Access a termination fee of $14.0 million. STAR will be
required to pay the termination fee:

     - if the STAR merger agreement is terminated by STAR because the STAR board
       of directors determines that an alternative proposal to acquire a
       majority of the stock or assets of STAR or in which the continuing STAR
       directors would not constitute a majority of the directors of the

                                       11
<PAGE>   25

       surviving entity would result in a more favorable transaction, from a
       financial point of view, to the STAR stockholders than the STAR merger;

     - if the STAR merger agreement is terminated by World Access because the
       STAR board of directors fails to recommend that the STAR stockholders
       approve the STAR merger or qualifies its recommendation in a manner
       adverse to World Access;

     - if the STAR merger agreement is terminated by World Access because the
       STAR board of directors approves or recommends an alternative proposal
       which the board of directors concludes would result in a more favorable
       transaction, from a financial point of view, to the STAR stockholders
       than the STAR merger; or

     - if the STAR merger agreement is terminated by World Access or STAR
       because the stockholders of STAR have not adopted the STAR merger
       agreement by the requisite vote, and STAR, within one year following the
       termination, enters into a definitive agreement with respect to a
       business combination of the type described in the STAR merger agreement.

NO OTHER NEGOTIATIONS INVOLVING STAR

     STAR agreed that until completion of the STAR merger or unless World Access
consents in writing, STAR will not directly or indirectly take any of the
following actions:

     - solicit, initiate, encourage or knowingly facilitate any inquiries
       regarding the acquisition of, or the making of a proposal to acquire, a
       material portion of the assets or stock of STAR or involving a business
       combination with STAR;

     - participate in any discussions or negotiations regarding a proposal to
       acquire a material portion of the assets or stock of STAR or involving a
       business combination with STAR;

     - disclose any confidential information with respect to a proposal to
       acquire a material portion of the assets or stock of STAR or involving a
       business combination with STAR; or

     - knowingly facilitate any effort or attempt to make, implement or accept a
       proposal to acquire a material portion of the assets or stock of STAR or
       involving a business combination with STAR.

     Notwithstanding the restrictions above, STAR may, in response to an
unsolicited, bona fide written proposal to acquire a material portion of the
assets or stock of STAR or for a business combination with STAR, (i) recommend
approval by its stockholders of such proposal or withdraw, modify or qualify in
a manner adverse to World Access its recommendation that the STAR stockholders
approve the STAR merger or (ii) furnish information and engage in discussions
regarding such proposal, provided that:

     - the STAR special meeting has not occurred;

     - with respect to recommending approval of such a proposal or changing the
       recommendation to the STAR stockholders regarding the approval of the
       STAR merger, the STAR board of directors concludes that such a proposal
       involving the acquisition of a majority of the assets or stock of STAR or
       in which the continuing STAR directors would not constitute a majority of
       the directors of the surviving entity would result in a more favorable
       transaction, from a financial point of view, to the STAR stockholders
       than the STAR merger and terminates the STAR merger agreement and pays
       the $14.0 million termination fee described above;

     - with respect to furnishing information or engaging in discussions
       regarding a proposal to acquire a majority of the assets or stock of STAR
       or in which the continuing STAR directors would not constitute a majority
       of the directors of the surviving entity, the STAR board of directors
       concludes that such proposal could reasonably be expected to result in a
       more favorable transaction, from a financial point of view, to the STAR
       stockholders than the STAR merger;

     - prior to providing information to the third party making a proposal to
       acquire a material portion of the assets or stock of STAR or for a
       business combination with STAR, STAR enters into a

                                       12
<PAGE>   26

       confidentiality agreement with such third party having terms at least as
       stringent as those contained in the confidentiality agreement between
       World Access and STAR; and

     - prior to providing information or entering into discussions with a third
       party, STAR notifies World Access of the third party inquiries, proposals
       or offers, including the identity of the third party and the material
       terms of the inquiries, proposals or offers.

MANAGEMENT SERVICES

     World Access and STAR intend to enter into an agreement pursuant to which
World Access will provide management services to STAR pending the completion of
the STAR merger.

STAR VOTING AGREEMENTS

     STAR stockholders Christopher E. Edgecomb and Samer Tawfik entered into
voting and stock transfer restriction agreements with World Access. The
agreements require these STAR stockholders to vote all shares of STAR common
stock beneficially owned by them in favor of the approval and adoption of the
STAR merger agreement and approval of the STAR merger. Mr. Edgecomb and Mr.
Tawfik also agreed to restrictions on the pre-closing transfer of their shares
of STAR common stock and post-closing transfer of shares of World Access common
stock received by them in the STAR merger. Subject to restrictions, Mr. Edgecomb
was given the right to have shares of World Access common stock issued to him in
the STAR merger registered with the Securities and Exchange Commission. Mr.
Edgecomb and Mr. Tawfik collectively held approximately [     %] of the voting
power of STAR capital stock as of the STAR record date.

OPINIONS OF WORLD ACCESS' AND STAR'S FINANCIAL ADVISORS

     In deciding to approve the STAR 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
STAR merger agreement. STAR's board considered the opinion of its financial
advisor, Deutsche Bank Securities, Inc., as to the fairness, from a financial
point of view, of the merger consideration to the STAR stockholders. The full
text of the written opinions of the financial advisors are attached to this
joint proxy statement/prospectus as Annex C and Annex E, respectively, and
should be read carefully in their entireties for a description of the
assumptions made, matters considered and limitations on the review undertaken.
The opinion of Donaldson, Lufkin, & Jenrette Securities Corporation is directed
to the World Access board, and the opinion of Deutsche Bank Securities, Inc. is
directed to the STAR board and was given prior to the announcement of the
WORLDxCHANGE merger agreement. These opinions do not constitute a recommendation
as to how to vote to any stockholders with respect to any matter relating to the
STAR merger.

CERTAIN MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE STAR MERGER

     Neither World Access, STI Merger Co. or STAR as the corporate parties, nor
STAR stockholders will recognize gain or loss for federal income tax purposes as
a result of participating in the STAR merger, except for:

     - cash received by STAR stockholders instead of fractional shares;

     - cash received by dissenting STAR stockholders who exercise appraisal
       rights; and

     - cash received by STAR stockholders if World Access elects to pay cash as
       part of the STAR merger consideration, in which case 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.

     World Access has received a legal opinion to this effect.

ACCOUNTING TREATMENT OF THE STAR MERGER

     We intend to account for the STAR merger as a purchase for financial
accounting purposes in accordance with United States generally accepted
accounting principles.

INTERESTS OF CERTAIN PERSONS IN THE STAR MERGER

     When considering the recommendations of World Access' and STAR's boards of
directors, you should be aware that certain World Access and STAR directors,
officers and stockholders have interests in the STAR merger that are different
from, or are in addition to, all other stockholders of World Access and STAR.
These interests include:

     - STAR's non-executive stock option committee determined that upon a change
       in control, all currently outstanding and future options held by Kelly
       Enos, Chief Financial Officer of STAR, and David Vaun Crumly, Executive
       Vice President of STAR, that have not vested, will become fully
       exercisable upon a change in control. The STAR merger constitutes a
       change in control under the agreement.

     - STAR has entered into an employment agreement with Mr. Crumly whereby
       upon the occurrence of a sale transaction, Mr. Crumly is entitled to
       receive a bonus equal to $1.5 million or a percentage of the monthly
       gross sales of accounts relating to customers introduced to STAR by Mr.
       Crumly.

     - World Access and Christopher Edgecomb have entered into a voting and
       stock transfer restriction agreement pursuant to which World Access
       granted to Mr. Edgecomb registration rights that entitle Mr. Edgecomb to
       include the shares of World Access common stock he receives in the STAR
       merger in any registration of capital stock for the account of World
       Access or any selling stockholder.

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

ANTITRUST AND DOMESTIC AND FOREIGN REGULATORY APPROVAL REQUIRED TO COMPLETE THE
STAR MERGER

     The STAR merger is subject to antitrust laws. World Access, STAR and other
related parties have made the required filings with the Department of Justice,
the Federal Trade Commission and the German Cartel Office. The Department of
Justice and the Federal Trade Commission granted an early termination of the
waiting period, effective March 16, 2000. No further action under the U.S.
antitrust laws is required, as long as the STAR merger is completed prior to
March 16, 2001. On May 18, 2000, the German Cartel office approved the STAR
merger. The Department of Justice, the Federal Trade Commission or the German
Cartel Office, as well as a foreign regulatory agency or government, state or
private person, may challenge the STAR merger at any time before or after its
completion.

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

RIGHTS OF DISSENTING STAR STOCKHOLDERS

     If pursuant to the terms of the STAR merger agreement, shares of STAR
common stock are converted, at the election of World Access, into the right to
receive both shares of World Access common stock and cash, other than cash in
lieu of fractional shares, STAR stockholders will have the right to demand
appraisal for their shares of STAR common stock.

                                       14
<PAGE>   28

     If the STAR merger is approved by the required vote of STAR stockholders
and is not abandoned or terminated and if the STAR stockholders will receive
cash other than cash in lieu of fractional shares in the STAR merger, the
holders of STAR common stock who did not vote in favor of or consent to the STAR
merger may be entitled to exercise appraisal rights pursuant to Section 262 of
the Delaware General Corporation Law, a copy of which is attached hereto as
Annex G. In order to exercise appraisal rights, STAR stockholders must take
certain steps, including, among others:

     - continuously holding the STAR common stock from the time of making a
       written demand for appraisal through the effective time of the STAR
       merger;

     - voting against the proposal to approve and adopt the STAR merger
       agreement;

     - delivering a written demand for appraisal to STAR before the taking of
       the vote on the STAR merger; and

     - filing a petition in the Court of Chancery of the State of Delaware
       demanding a determination of the fair value of the STAR common stock
       within 120 days after the date of the completion of the STAR merger.

     Fair value would be determined by the Court of Chancery of the State of
Delaware exclusive of any element of value arising from the STAR merger. Failure
to take any of the above actions required under Section 262 will result in a
loss of such statutory appraisal rights.

RESTRICTIONS ON THE ABILITY TO SELL WORLD ACCESS STOCK

     All shares of World Access common stock received by STAR stockholders in
connection with the STAR merger will be freely transferable unless the holder is
considered an affiliate of World Access or STAR under the Securities Act of
1933.

                            SUMMARY OF THE PT-1 SALE

THE PT-1 SALE

     As a condition to World Access' obligation to complete the STAR merger,
STAR is required to sell its wholly-owned subsidiary, PT-1 Communications, Inc.,
for net cash proceeds of at least $150.0 million.

     STAR has entered into a letter of intent with a third party, PT-1 acquiror,
for the sale of certain assets of PT-1 and the assumption of certain liabilities
for $150.0 million, subject to adjustment based on the net worth of the assets
of PT-1 on the closing date. There can be no guarantee that the terms of a
definitive agreement between STAR and PT-1 acquiror, or any other buyer, will
contain the terms set forth in the PT-1 letter of intent. Further, as of the
date of this joint proxy statement/prospectus, there can be no guarantee that
completion of the sale of PT-1 to PT-1 acquiror, or any other buyer, will
satisfy the condition precedent to World Access' obligation to complete the STAR
merger.

     STAR is seeking stockholder approval to proceed with the PT-1 sale to PT-1
acquiror, or in the event that STAR does not reach a definitive agreement with
PT-1 acquiror, to such other buyer and on such other terms as the STAR board of
directors shall subsequently approve, subject to the minimum requirements set
forth in the accompanying joint proxy statement/prospectus, including STAR's
receipt of a sales price of at least $            , obtaining the opinion of
STAR's financial advisor in connection with the sale and approval by the STAR
board of directors of a definitive sale agreement containing terms that the STAR
board of directors determines to be in the best interests of STAR. STAR has
entered into the PT-1 letter of intent with PT-1 acquiror for the PT-1 sale and
STAR anticipates that it will enter into a definitive agreement with PT-1
acquiror. This joint proxy statement/prospectus describes the PT-1 letter of
intent in detail. Except as requested in the accompanying joint proxy
statement/prospectus, STAR will not solicit any further stockholder vote for the
PT-1 sale. Accordingly, STAR stockholders will not have the opportunity to vote
on the definitive PT-1 sale agreement.

     The PT-1 letter of intent is attached to this joint proxy
statement/prospectus as Annex F. STAR encourages the STAR stockholders to read
the PT-1 letter of intent carefully. The PT-1 letter of intent is more fully
described on page 102.

NEGOTIATION OF DEFINITIVE AGREEMENT WITH PT-1 ACQUIROR

     STAR and PT-1 acquiror have agreed to proceed diligently and in good faith
to negotiate, execute and deliver a definitive agreement in connection with the
sale of PT-1 to PT-1 acquiror. The terms of the definitive agreement are subject
to negotiation and may differ substantially from the terms of the PT-1 letter of
intent. In the event that STAR and PT-1 acquiror are unable to reach a
definitive agreement, STAR will proceed with the PT-1 sale to such other buyer
and on such other terms as the STAR board of directors shall subsequently
approve, subject to the minimum requirements set forth in this joint proxy
statement/prospectus, including STAR's receipt of a sales price of at least
$          , obtaining the opinion of STAR's financial advisor in connection
with the sale and approval by the STAR board of directors of a definitive sale
agreement containing terms that the STAR board of directors determines to be in
the best interests of STAR.

TERMS OF THE DEFINITIVE AGREEMENT WITH PT-1 ACQUIROR

     STAR is currently negotiating a definitive agreement with PT-1 acquiror
based on the terms of the PT-1 letter of intent. In addition, negotiation of the
final PT-1 sale agreement is subject to satisfactory completion of a due
diligence review of PT-1 by PT-1 acquiror.

     Pursuant to the PT-1 letter of intent, PT-1 acquiror has agreed to pay STAR
$150.0 million in cash for certain assets of PT-1, provided that the purchase
price may be adjusted upward or downward to the extent that the net value of the
purchased assets, less liabilities assumed by PT-1 acquiror, as set forth on the
balance sheet to be delivered as soon as practicable following the closing, is
greater than or less than $37,223,490. PT-1 acquiror will only assume PT-1's (i)
accounts payable and accrued expenses, (ii) accrued taxes payable, (iii)
short-term debt, (iv) deferred revenue and (v) long-term debt.
                                       16
<PAGE>   30

     The PT-1 letter of intent provides that the definitive agreement will
contain, among other things, representations and warranties, covenants,
conditions and indemnification provisions appropriate for such agreements. The
PT-1 letter of intent further provides that:

     - the representations and warranties of STAR will survive the close of the
       PT-1 sale for two years (other than those in respect of tax matters,
       which will survive the close of the PT-1 sale until the expiration of the
       applicable statute of limitations);

     - STAR and PT-1 acquiror will proceed diligently and in good faith to file
       all documents necessary to satisfy any applicable waiting period under
       the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended;

     - STAR will obtain all material third-party consents to the transactions
       contemplated by the PT-1 letter of intent, provided such condition may be
       waived by PT-1 acquiror in its sole discretion;

     - STAR shall use reasonable efforts to identify, with PT-1 acquiror, key
       employees and to cause certain of STAR's key executives to enter into
       employment agreements and non-competition agreements with PT-1 acquiror;
       and

     - STAR shall cause PT-1 to conduct the business and operations of PT-1 in
       the ordinary course consistent with past practice.

THE PT-1 SALE CLOSING DATE

     STAR and PT-1 acquiror have agreed to proceed diligently and in good faith
to complete the close of the PT-1 sale by the earlier of (i) the close of the
STAR merger or (ii) June 30, 2000.

VOTE REQUIRED FOR APPROVAL

     The holders of a majority of the outstanding shares of STAR common stock
must approve the PT-1 sale. STAR stockholders are entitled to cast one vote per
share owned as of [          ], 2000, the STAR record date.

     Christopher E. Edgecomb, a STAR stockholder holding [     %] of the
outstanding common stock of STAR, has agreed to vote in favor of the PT-1 sale.
Directors and officers of STAR collectively beneficially owned approximately
[     %] of the outstanding common stock of STAR as of the STAR record date.

TERMINATION FEE

     Pursuant to the PT-1 letter of intent, if the PT-1 sale agreement is
terminated for certain reasons, STAR will be required to pay PT-1 acquiror a
termination fee of $5.85 million. STAR will be required to pay the termination
fee if STAR fails or refuses to consummate the PT-1 sale for any reason other
than:

     - the failure to obtain necessary regulatory approval for the PT-1 sale;

     - the failure of a majority of the outstanding shares of STAR common stock
       to approve the PT-1 sale, provided STAR does not sell PT-1 to a third
       party within twelve months of the stockholder vote;

     - PT-1 acquiror's breach of the material terms and conditions of the
       definitive PT-1 sale agreement; or

     - the mutual written consent of STAR and PT-1 acquiror.

                                       17
<PAGE>   31

NO OTHER NEGOTIATIONS INVOLVING PT-1

     STAR has agreed not to:

     - solicit, discuss or encourage the making of any inquiry, offer or
       proposal which constitutes or is reasonably likely to lead to an
       acquisition proposal; or

     - accept or entertain an offer by any person other than PT-1 acquiror, or
       enter into discussions with, or provide information to any person, other
       than PT-1 acquiror, concerning an acquisition proposal.

     STAR has agreed that it will keep PT-1 acquiror informed of any acquisition
proposal.

STAR VOTING AGREEMENT

     The PT-1 letter of intent requires Mr. Edgecomb, a STAR stockholder, to
enter into a voting agreement with PT-1 acquiror. The agreement will require Mr.
Edgecomb to vote all shares of STAR common stock beneficially owned by him in
favor of the approval of the PT-1 sale. Mr. Edgecomb held approximately [     %]
of the outstanding capital stock of STAR as of the STAR record date.

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

     If STAR completes the PT-1 sale with PT-1 acquiror, or with another buyer
on terms like those set forth in the PT-1 letter of intent, for cash, PT-1 will
recognize substantial gain from the sale, which will only be partially offset by
STAR's net operating loss carryovers and 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 SALE

     If STAR completes the sale of PT-1's assets to PT-1 acquiror, or with
another buyer on terms like those set forth in the PT-1 letter of intent, for
cash, STAR intends to account for the PT-1 sale as a sale of assets in
accordance with United States generally accepted accounting principles.

INTERESTS OF CERTAIN PERSONS IN THE PT-1 SALE

     When considering the recommendation of STAR's board of directors, you
should be aware that certain STAR directors, officers and stockholders have
interests in the STAR merger, of which the PT-1 sale is a condition precedent,
that are different from, or are in addition to, all other stockholders of STAR.
These interests are described on page 85.

     Kaufman Brothers, STAR's financial advisor in connection with the PT-1
sale, has been engaged to issue a fairness opinion to STAR's board of directors
in connection with sale and is entitled to certain fees and expense
reimbursements regardless of whether the PT-1 sale is consummated.

ANTITRUST AND OTHER REGULATORY APPROVAL REQUIRED TO COMPLETE THE PT-1 SALE

     The PT-1 sale is subject to antitrust laws. STAR and PT-1 acquiror or such
other buyer, will make the required filings with the Department of Justice and
the Federal Trade Commission. However, the companies will not be permitted to
complete the PT-1 sale until the applicable waiting periods have expired or
terminated. The Department of Justice or the Federal Trade Commission, as well
as a state or private person, may challenge the PT-1 sale at any time before or
after its completion.

                       SUMMARY OF THE WORLDXCHANGE MERGER

THE WORLDXCHANGE MERGER

     In the WORLDxCHANGE merger, WORLDxCHANGE will merge into a wholly-owned
subsidiary of World Access, with the surviving company continuing as a
wholly-owned subsidiary of World Access.

     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 upon the
satisfaction of the conditions for such payment contained in the WORLDxCHANGE
merger agreement and to make the necessary conforming changes. The WORLDxCHANGE
merger agreement and the amendment to the WORLDxCHANGE merger agreement are
attached to this joint proxy statement/prospectus as Annex B. The original
WORLDxCHANGE merger agreement as amended is referred to in this joint proxy
statement/prospectus as the WORLDxCHANGE merger agreement. World Access
encourages you to read the WORLDxCHANGE merger agreement carefully. The
WORLDxCHANGE merger agreement is more fully described on page 129.

     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
       World Access' operations;

     - providing a stronger telecommunications company during the consolidation
       trend in the international telecommunications services industry; and

     - combining growing retail operations and adding diversified revenues.

     There are potential risks to the WORLDxCHANGE merger, including:

     - profitability may not be achieved, and World Access and WORLDxCHANGE will
       incur significant merger-related expenses;

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

     - market share may decrease, and we may face pricing pressures if we 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 our
       services and products.

     The potential benefits from the WORLDxCHANGE merger may not be achieved.

pursuant to the WORLDxCHANGE merger agreement. The full text of the written
opinion of World Access' financial advisor is attached to this joint proxy
statement/prospectus as Annex D and should be read carefully in its entirety for

Corporation is directed to the Word Access board. This opinion does not

CERTAIN MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE WORLDXCHANGE MERGER

     Neither World Access, WORLDxCHANGE Communications, Inc. f/k/a CTI Merger

       rights; and

INTERESTS OF CERTAIN PERSONS 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:

     - Under the terms of the WORLDxCHANGE merger agreement, World Access has
       agreed to cause one designee of WORLDxCHANGE to be elected to the World
       Access board of directors. 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 record date for determining the WORLDxCHANGE shareholders
       entitled to approve the WORLDxCHANGE merger, executive officers and
       directors of WORLDxCHANGE and Gold & Appel Transfer S.A. and Atocha, L.P.
       collectively beneficially owned a total of        shares of WORLDxCHANGE
       common stock (not including any shares subject to outstanding options or
       warrants beneficially owned by these individuals or entities). Under the
       WORLDxCHANGE merger agreement, these shares will be converted in the
       WORLDxCHANGE merger into a total of        shares of World Access common
       stock with an aggregate value of $       (assuming a per share value of
       World Access common stock equal to $20.38). In addition, as of the record
       date for determining the WORLDxCHANGE shareholders entitled to approve
       the WORLDxCHANGE merger, these individuals and entities collectively
       owned options and warrants to purchase a total of           shares of
       WORLDxCHANGE common stock at exercise prices ranging from $       to
       $       per share. Under the WORLDxCHANGE merger agreement, these options
       and warrants will be converted into the right to acquire shares of World
       Access common stock in accordance with the WORLDxCHANGE merger agreement.

     - Each of Roger Abbott, Chief Executive Officer and director of
       WORLDxCHANGE, Edward Soren, Executive Vice President and director of
       WORLDxCHANGE, Gold & Appel Transfer S.A. and Atocha L.P. has agreed in
       his or its voting and stock transfer restriction agreement with World
       Access not to sell or otherwise transfer the World Access shares received
       by him or it in the WORLDxCHANGE merger until six months after the
       completion of the WORLDxCHANGE merger. However, Mr. Soren's agreement
       permits Mr. Soren immediately to sell up to 750,000 shares of World
       Access common stock to be received by Mr. Soren in the WORLDxCHANGE
       merger without restriction. In addition, Mr. Abbott's agreement permits
       Mr. Abbott immediately to sell such number of shares of World Access
       common stock to be received by Mr. Abbott in the WORLDxCHANGE merger as
       would provide Mr. Abbott with gross proceeds of up to $30.0 million.

     - Under Mr. Abbott's employment agreement with WORLDxCHANGE, if, in
       connection with a change of control of WORLDxCHANGE or otherwise, Mr.
       Abbott's employment with WORLDxCHANGE is terminated other than for cause,
       death or disability, or if Mr. Abbott's employment is constructively
       terminated, Mr. Abbott will be entitled to the payment of any earned but
       unpaid salary and/or bonus under the agreement and a lump sum cash
       payment in an amount equal to the amount he would have earned under the
       agreement from the date of termination through July 31, 2002 (currently
       $50,000 per month) plus the cost for Mr. Abbott to obtain benefits
       equivalent to those in effect at the time of the termination through July
       31, 2002. The WORLDxCHANGE merger is a change of control under Mr.
       Abbott's employment agreement and the employment agreements discussed
       below.

     - Patrick Aelvoet, WORLDxCHANGE's Chief Financial Officer, has an
       employment agreement with WORLDxCHANGE that provides for the payment of a
       $50,000 severance payment to Mr. Aelvoet if, in connection with a change
       of control of WORLDxCHANGE or otherwise,

                                       25
<PAGE>   39

       WORLDxCHANGE terminates Mr. Aelvoet's employment without cause and
       without at least 90 days' advance notice of such termination. In
       addition, Mr. Aelvoet's employment agreement provides for the payment of
       a $25,000 bonus to Mr. Aelvoet if the WORLDxCHANGE merger is completed
       prior to May 30, 2000, regardless of whether Mr. Aelvoet's employment is
       terminated following the WORLDxCHANGE merger.

     - Pursuant to three separate stock option agreements with WORLDxCHANGE, Mr.
       Aelvoet has options to purchase an aggregate of 150,000 shares at prices
       ranging from $9.00 per share to $11.00 per share. Under the WORLDxCHANGE
       merger agreement, all of these options will, to the extent not exercised
       by Mr. Aelvoet as of immediately prior to the WORLDxCHANGE merger, be
       converted into the right to acquire shares of World Access common stock
       in accordance with the merger agreement. Under Mr. Aelvoet's option
       agreements, if his employment with WORLDxCHANGE is involuntarily
       terminated within 12 months following a change of control of
       WORLDxCHANGE, his unvested options would become immediately fully vested
       and remain exercisable until the earlier of one year from the date of
       such termination or ten years from the applicable grant date.

     - Eric G. Lipoff, WORLDxCHANGE's Vice President and General Counsel, has an
       employment agreement with WORLDxCHANGE that provides that, if in
       connection with a change of control of WORLDxCHANGE or otherwise,
       WORLDxCHANGE terminates Mr. Lipoff's employment without cause or there is
       otherwise an involuntary termination of Mr. Lipoff's employment, Mr.
       Lipoff will be entitled to the payment of any earned but unpaid salary
       and/or bonus under the agreement and the amount of compensation that he
       would have earned under the agreement from the date of such termination
       through December 31, 2002 (currently $16,666 per month) plus the cost for
       Mr. Lipoff to obtain benefits equivalent to those in effect at the time
       of the termination through December 31, 2002.

     - Mr. Lipoff has an option to purchase a total of 150,000 shares of
       WORLDxCHANGE common stock at $10.00 per share. Under the WORLDxCHANGE
       merger agreement, this option will be converted into the right to acquire
       shares of World Access common stock in accordance with the WORLDxCHANGE
       merger agreement. Pursuant to Mr. Lipoff's option agreement, this option
       will fully vest on December 31, 2002, except that the options will
       immediately fully vest if Mr. Lipoff's employment with WORLDxCHANGE is
       terminated without cause or there is otherwise an involuntary termination
       of Mr. Lipoff's employment at any time prior to December 31, 2002.
       Options the vesting of which is so accelerated would remain exercisable
       until 90 days from the date Mr. Lipoff's employment is so terminated.

     - Effective January 3, 2000, each of Sen. Paul Laxalt and Dann Angeloff,
       who are directors of WORLDxCHANGE, received an option to purchase 12,500
       shares of WORLDxCHANGE common stock at $10.00 per share. Under the
       WORLDxCHANGE merger agreement, these options will, to the extent not
       exercised by Sen. Laxalt and Mr. Angeloff, as applicable, as of the
       effective time of the WORLDxCHANGE merger, be converted into the right to
       acquire shares of World Access common stock in accordance with the
       WORLDxCHANGE merger agreement. The option agreements with respect to
       these options provide for the immediate vesting in full of these options
       upon a change of control of WORLDxCHANGE. If the vesting of these options
       is so accelerated, they would remain exercisable until the earlier of the
       day before the first anniversary of the termination of the optionee as a
       WORLDxCHANGE director following such change of control or ten years from
       the option grant date.

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

                                       26
<PAGE>   40

boards. However, the companies are not permitted to complete the WORLDxCHANGE
merger until the 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.

RIGHTS OF DISSENTING WORLDXCHANGE SHAREHOLDERS

     The WORLDxCHANGE shareholders may be entitled to exercise dissenters'
rights pursuant to Chapter 13 of the California Corporations Code, a copy of
which is attached hereto as Annex H. 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
       WORLDxCHANGE 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.

     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. 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/or whether the
shares qualify as dissenting shares.

     Dissenting shares lose their status as dissenting shares and the holders of
dissenting shares cease to be dissenting shareholders and cease to be entitled
to require WORLDxCHANGE to purchase their shares if:

     - the WORLDxCHANGE merger is abandoned;

     - 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 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.

    1998; Comm/Net -- May 1999; and FaciliCom -- December 1999.
(2) EBITDA from continuing operations consists of earnings (loss) before net
    interest expense (income), income taxes, foreign exchange gains or losses,
    depreciation and amortization. EBITDA should not be considered as a
    substitute for operating earnings, net income (loss), cash flow or other
    combined statement of operations or cash flow data computed in accordance
    with generally accepted accounting principles or as a measure of our results
    of operations or liquidity. EBITDA is widely used as a measure of a
    company's operating performance and its ability to service its indebtedness
    because it

(1) EBITDA represents operating loss plus depreciation and amortization expense.
    WORLDxCHANGE has included information concerning EBITDA herein because such
    information is commonly used in the telecommunications industry as one
    measure of an issuer's operating performance and historical ability to
    service debt. EBITDA is not determined in accordance with generally accepted
    accounting principles, is not indicative of cash provided by operating
    activities, is not necessarily comparable to similarly titled measures of
    other companies, 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.

     The following table reconciles our net loss to EBITDA:

                                  RISK FACTORS

     THE STAR MERGER, INCLUDING THE PT-1 SALE, AND THE WORLDXCHANGE MERGER
INVOLVE A HIGH DEGREE OF RISK. UPON COMPLETION OF THE STAR MERGER AND THE
WORLDXCHANGE MERGER, THE STAR STOCKHOLDERS AND WORLDXCHANGE SHAREHOLDERS WHO DO
NOT PERFECT DISSENTERS' RIGHTS WILL RECEIVE WORLD ACCESS COMMON STOCK. AN
INVESTMENT IN WORLD ACCESS COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. 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 MERGERS

WE MAY NOT ACHIEVE ANTICIPATED BENEFITS FROM INTEGRATION OF OPERATIONS.

     The mergers require the integration in a timely manner of three companies
that previously operated independently. We will have to combine our workforces
and integrate our offices. We may require some employees to relocate as part of
this process. We expect that we will, as a result of our increased size and
requirements, be able to consolidate our purchasing and obtain more favorable
prices from suppliers. However, our ability to do so may be limited by changes
in the purchasing power or practices of our competitors and other market
dynamics. No assurance can be given that we will be able to integrate our
operations without encountering difficulties or experiencing the loss of key
employees or that the cost savings and synergies expected from integration will
be realized. The consolidation of operations will require substantial attention
from management. The diversion of management's attention and any difficulties
encountered in the transition and integration process could have a material
adverse effect on our revenues, levels of expenses and operating results and
damage our relationship with our key customers and employees.

WE MAY NOT BE ABLE TO ACHIEVE PROFITABILITY.

     On a pro forma basis, after giving effect to the mergers and certain other
transactions, World Access would have had a loss from continuing operations for
the three months ended March 31, 2000 of $0.72 per diluted share as compared to
the $0.56 loss per diluted share from continuing operations for the same period
on a stand alone basis. Despite anticipated benefits of the mergers, we may not
achieve profitability.

WORLD ACCESS, STAR AND WORLDXCHANGE WILL INCUR SIGNIFICANT MERGER-RELATED
CHARGES.

     We will incur significant consolidation and integration expenses. In
addition, World Access, STAR and WORLDxCHANGE will incur merger-related expenses
of approximately $6.0 million, including investment banking, legal and
accounting fees and financial printing and other related charges. The foregoing
amounts are preliminary, and the actual amounts may be higher or lower.
Moreover, we may incur additional unanticipated expenses in connection with the
integration of our businesses.

WE MAY NOT SUCCESSFULLY INTEGRATE THE NETWORKS OF STAR AND WORLDXCHANGE INTO THE
WORLD ACCESS NETWORK.

     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 our business if not completed in a timely and efficient manner. Extended
network downtime could have a material adverse effect on our revenues and our
relationships with our customers. No assurance can be given that we will be able
to successfully integrate the networks of STAR and WORLDxCHANGE into the World
Access network.

OUR INCREASED FINANCIAL LEVERAGE WILL SUBJECT US TO SIGNIFICANT OPERATING AND
FINANCIAL RESTRICTIONS.

     Immediately subsequent to the consummation of the mergers, we 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

                                       38
<PAGE>   52

million of long-term debt and negative stockholders' equity. Based on World
Access' pro forma balance sheet at March 31, 2000, as a result of the
consummation of the mergers and certain other transactions, we would have had
long-term debt of $524.0 million and a total debt to equity ratio of 38.1%.

     Our combined indebtedness could have serious negative consequences. For
example, it could:

     - limit our ability to obtain additional financing for working capital,
       capital expenditures or other purposes or to obtain such financing on
       favorable terms;

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

     - make it difficult for us to meet our debt service requirements or force
       us to modify our operations if there is a substantial decrease in
       operating income and cash flows or an increase in expenses;

     - limit our flexibility to react to changes in our businesses and the
       industry in which we operate and make us more vulnerable to downturns and
       competitive pressures in our businesses; and

     - require us to redeem a substantial portion of our outstanding debt
       securities upon the sale of certain portions of the World Access
       Equipment Group.

     There is no assurance that we will be able to meet the obligations on our
outstanding indebtedness. World Access anticipates that its 2000 pro forma debt
service payments will be approximately $415.0 million exclusive of any
obligation to redeem our outstanding debt securities. If we are unable to
generate sufficient cash flow or to otherwise obtain funds necessary to meet our
obligations, or if we do not comply with the various covenants under our
indebtedness, we will be in default under the terms of that debt. If we default,
the holders of indebtedness can accelerate the maturity of the indebtedness that
is owed to them, and this could cause defaults under our other indebtedness.

DECREASED CASH FLOW MAY LIMIT OUR ABILITY TO CONTINUE TO MAKE CAPITAL
EXPENDITURES FOR THE ACQUISITION AND DEVELOPMENT OF OUR INTERNATIONAL
TELECOMMUNICATIONS NETWORK.

     We believe that we must continue to enhance and expand our network and
build out our telecommunications network infrastructure in order to maintain our
competitive position and continue to meet the increasing demands for service
quality, capacity and competitive pricing. We will need to raise additional
capital from equity or debt sources if our cash flow from operations is
insufficient to meet our capital expenditure and working capital requirements.
If our available cash flow substantially decreases as a result of lower
telecommunications prices or for other reasons, we may have limited ability to
continue to make capital expenditures for the acquisition and development of our
international telecommunications network. If cash flow from operations is not
sufficient to satisfy our capital expenditure requirements, there can be no
assurance that additional debt or equity financing or other sources of capital
will be available to meet our requirements.

VOTING INTERESTS OF CURRENT WORLD ACCESS STOCKHOLDERS WILL BE SUBSTANTIALLY
DILUTED.

     Following the completion of the mergers, the current World Access
stockholders (i) will own shares representing approximately 63.0% of our total
voting power and (ii) will own 65.0% of the total number of outstanding shares
of our common stock on a fully diluted basis. 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. 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 (i) will own shares representing approximately 78.0%
of the total voting power of World Access after completion of the STAR merger
and (ii) will own 80.0% of the total number of outstanding shares of World
Access common stock on a fully diluted basis after completion of STAR merger. If
only the WORLDxCHANGE merger is completed, the current World Access stockholders
(i) will own shares representing approximately 76.0% of the total voting power
of World Access after

                                       39
<PAGE>   53

completion of the WORLDxCHANGE merger and (ii) will own 77.0% of the total
number of outstanding shares of World Access common stock on a fully diluted
basis after completion of the WORLDxCHANGE merger.

SALES OF LARGE AMOUNTS OF OUR SHARES FOLLOWING THE MERGERS COULD ADVERSELY
AFFECT THE PRICE OF OUR COMMON STOCK.

     The market price of our common stock could fall significantly if
stockholders sell large amounts of stock in the public market following the
mergers. These sales, or the possibility that these sales may occur, could make
our stockholders unable to realize the value of the merger consideration
received, as measured prior to completion of the mergers, and may make it more
difficult for us to sell equity or equity-related securities in the future.
After the mergers, all of the shares of our stock issued in the mergers will be
eligible for immediate sale except shares held by affiliates of the companies
that will be subject to limitations on the volume of sales under federal
securities laws. In addition, some of our stockholders will have the right to
demand registration of their shares for resale after the mergers.

BENEFITS OF THE STAR MERGER OR THE WORLDXCHANGE MERGER WILL NOT BE AVAILABLE TO
WORLD ACCESS STOCKHOLDERS IF EITHER OF THESE MERGERS IS NOT COMPLETED.

     None of the benefits identified by World Access and STAR as reasons for the
STAR merger will be realized by World Access stockholders if the STAR merger is
not completed. Likewise, none of the benefits identified by World Access and
WORLDxCHANGE as reasons for the WORLDxCHANGE merger will be realized by World
Access stockholders if the WORLDxCHANGE merger is not completed. Nevertheless,
neither merger is conditioned on the completion of the other merger.

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

     On March 29, 2000, STAR entered into a letter of intent with a third party,
PT-1 acquiror, for the sale of all of the assets of PT-1. Pursuant to the terms
of the PT-1 letter of intent, PT-1 acquiror will pay $150.0 million in cash for
the assets of PT-1, less certain liabilities and subject to a purchase price
adjustment based on the results of a final audit to be conducted after the close
of the PT-1 sale. While STAR expects that it will successfully complete the PT-1
sale, there can be no assurance that STAR will complete the PT-1 sale or that
STAR will find another purchaser for PT-1. Further, there can be no assurance
that STAR will complete the PT-1 sale to PT-1 acquiror, or to any other
purchaser, for net cash proceeds of at least $150.0 million, as required by the
STAR merger agreement.

     If STAR does not successfully complete the PT-1 sale to PT-1 acquiror, STAR
will attempt to sell PT-1 to an alternative buyer subject to the minimum
requirements set forth in this joint proxy statement/prospectus, including
STAR's receipt of a sales price of at least $       , obtaining the opinion of
STAR's financial advisor in connection with the sale and approval by the STAR
board of directors of a definitive sale agreement containing terms that the STAR
board of directors determines to be in the best interests of STAR.

     Pursuant to the terms of the STAR merger agreement, if STAR fails to sell
PT-1 for net cash proceeds of at least $150.0 million, then World Access does
not have to complete the STAR merger. 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 may need to obtain
additional capital. STAR is not certain that it will be able to raise additional
capital on favorable terms or at all.

     While STAR believes it will complete the PT-1 sale to PT-1 acquiror, the
completion of the PT-1 sale is subject to certain conditions, including, among
others: (i) negotiation of a definitive PT-1 sale agreement, (ii) the expiration
of the waiting period applicable to the PT-1 sale under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, and (iii) the receipt of all
material third party

                                       40
<PAGE>   54

consents and approvals required of PT-1 to complete the PT-1 sale. Accordingly,
there can be no assurance that all such conditions will be satisfied. In
addition, the PT-1 letter of intent provides that the PT-1 sale will be subject
to termination under certain circumstances, including, among others: (i) by the
nonbreaching party in the event of a breach of any material terms or conditions
contained in the PT-1 sale agreement, (ii) if the necessary regulatory approvals
are not obtained or (iii) if the PT-1 sale agreement is not approved by STAR's
stockholders. STAR cannot guarantee that the PT-1 sale will be consummated with
PT-1 acquiror or any other buyer. If STAR does not enter into a definitive PT-1
sale agreement with PT-1 acquiror 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 a definitive PT-1 sale agreement is negotiated with
PT-1 acquiror and subsequently terminated, STAR may face significant costs
associated with the failed PT-1 sale, including a termination fee of $5.85
million.

     In addition, the completion of the PT-1 sale to PT-1 acquiror for cash
proceeds of at least $150.0 million is dependent, in part, on the results of a
final audit to be conducted after the close of the PT-1 sale. There can be no
assurance that the net value of the assets of PT-1 will be greater than or equal
to the value of the assets as originally presented to PT-1 acquiror, which may
result in cash proceeds of less than $150.0 million for the PT-1 sale. If STAR
fails to complete the PT-1 sale prior to the close of the STAR merger or to sell
the assets of PT-1 for net cash proceeds of greater than $150.0 million, the
STAR merger may not close.

RISK FACTORS CONCERNING WORLD ACCESS, STAR AND WORLDXCHANGE

OUR INABILITY TO INTEGRATE ACQUIRED COMPANIES COULD RESULT IN SUBSTANTIAL COSTS
AND MAY DAMAGE OUR RELATIONSHIPS WITH OUR KEY CUSTOMERS AND EMPLOYEES.

     An element of our growth strategy is to acquire companies that complement
or expand our existing business. If we are unable to successfully integrate
acquired businesses, we may not be able to realize anticipated cost
efficiencies, operational and other benefits in a timely manner, and we may
incur substantial costs and delays or other operational, technical or financial
problems. In addition, the failure to successfully integrate acquisitions may
divert management's attention from our existing business and may damage our
relationships with our key customers and employees.

FUTURE ACQUISITIONS MAY SIGNIFICANTLY DECREASE OUR STOCKHOLDERS' PERCENTAGE
OWNERSHIP, REDUCE OUR PROFITABILITY AND HINDER OUR ABILITY TO RAISE CAPITAL.

     We may issue securities in future acquisitions that could significantly
reduce our stockholders' equity ownership and reduce our earnings on a per share
basis. We also may incur additional debt and amortization expense related to
goodwill and other intangible assets acquired in future acquisitions. This
additional debt and amortization expense may reduce significantly our
profitability and hinder our ability to raise capital in the future.

WE MAY BE UNABLE TO MANAGE EFFECTIVELY OUR RAPID GROWTH, WHICH MAY MATERIALLY
ADVERSELY AFFECT THE QUALITY OF OUR PRODUCTS AND SERVICES AND OUR ABILITY TO
RETAIN KEY PERSONNEL.

     Our rapid growth from recent acquisitions and the expansion of our
operations has placed significant demands on our resources. In addition, we
expect that our 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 we are unable to manage our growth effectively, the quality of our
products and services and our ability to retain key personnel could be adversely
affected. To successfully manage our growth, we must

                                       41
<PAGE>   55

continue to improve our operational, financial and management information
systems and to motivate and effectively manage our employees.

WE MAY SUSTAIN MATERIAL LIABILITY AS A RESULT OF STOCKHOLDER SUITS AGAINST US.

     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. We may have to pay substantial damages if
the plaintiffs are successful in their actions.

RESTRICTIONS UNDER OUR CREDIT FACILITY MAY REQUIRE US TO MAKE BUSINESS DECISIONS
THAT ARE ADVERSE TO OUR LONG TERM INTERESTS AND THE INTERESTS OF OUR
STOCKHOLDERS.

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

     Upon a default under our credit facility, the lenders may require us to
immediately repay the entire amount outstanding under the credit facility. If we
cannot repay these borrowings, we may need to seek the protection of the federal
bankruptcy laws to continue operating our business, and possibly sell our
assets, which would have a material adverse effect on our business and our
relationships with customers, suppliers and employees. Even if we were able to
repay all amounts owed under the credit facility, our business, financial
condition and results of operations would be materially adversely affected due
to the resulting loss in liquidity. In addition, in the event of a default under
the credit facility that we do not cure, the lenders could foreclose on the
collateral securing our obligations, which would result in the lenders owning
and having effective control over our operations and possibly in the sale of our
assets, which would have a material adverse effect on our business and our
relationships with customers, suppliers and employees.

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

     STAR is subject to certain restrictions under its financing arrangements,
including its financing arrangements with WorldCom Network Services, Inc. and
RFC Capital Corporation and its anticipated financing arrangement with World
Access. 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 accelerate payment on any of STAR's debt, it could force STAR to file
for bankruptcy or reorganize its business. Under STAR's financing arrangements
with WorldCom and its anticipated financing arrangement with World Access, 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, World
Access and WorldCom can accelerate payment of the outstanding balance. STAR's
anticipated financing arrangement with World Access will provide for a
predetermined initial advance with additional advances to be made solely in
World Access' discretion. 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.

<PAGE>   56

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 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.

STAR MAY NOT HAVE SUFFICIENT CASH FLOW FROM ITS BUSINESS TO PAY ITS DEBT.

     The amount of STAR's outstanding debt is large compared to its cash flow
and the net book value of its assets. STAR has substantial repayment obligations
under its outstanding debt. As of March 31, 2000, STAR had:

        - Total consolidated debt of approximately $184.3 million, including
          $82.0 million outstanding pursuant to its financing arrangement with
          RFC and including its financing arrangement with WorldCom which was
          entered into on April 12, 2000; and

        - Stockholders' equity of approximately $270.1 million.

                                       43
<PAGE>   57

     The following chart shows the aggregate 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 accelerate payment of the amounts due
under its financing arrangements. Also, because the interest rates under some of
its financing 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 may
not generate enough cash from its operations to meet these obligations. STAR has
entered into a letter of intent with PT-1 acquiror to sell the assets of PT-1
for cash proceeds of $150.0 million less certain liabilities and subject to a
purchase price adjustment. In the event that STAR does not reach a definitive
agreement with PT-1 acquiror, STAR will attempt to sell PT-1 to another buyer
subject to the minimum requirements set forth in this joint proxy
statement/prospectus, including STAR's receipt of a sales price of at least
$          , obtaining the opinion of STAR's financial advisor in connection
with the sale and approval by the STAR board of directors of a definitive sale
agreement containing terms that the STAR board of directors determines to be in
the best interests of STAR. STAR expects that the proceeds it receives from the
sale 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 sale to
PT-1 acquiror will close, that STAR will find an alternative buyer for PT-1 or
that the proceeds STAR receives from the PT-1 sale will be sufficient.

AS A HOLDING COMPANY, OUR LIQUIDITY COULD BE ADVERSELY AFFECTED IF OUR
SUBSIDIARIES ARE UNABLE TO DISTRIBUTE MONEY TO US.

     As a holding company without significant income from operations, we are
dependent upon the income from our operating subsidiaries to meet our operating
expenses. If our operating subsidiaries are unable to pay dividends or otherwise
distribute amounts to us sufficient to cover our operating expenses, then we may
be subject to liquidity problems, even if, on a consolidated basis, our
operating subsidiaries are profitable.

WE MAY LOSE MARKET SHARE AND FACE PRICING PRESSURES IF WE ARE NOT ABLE TO
COMPETE SUCCESSFULLY WITH OTHER TELECOMMUNICATIONS FIRMS.

     The segments of the telecommunications industry in which we operate are
intensely competitive. We believe that competition will continue to increase,
placing downward pressure on prices, thus adversely affecting our gross margins.
Many of the companies with whom we compete have significantly more extensive
engineering, manufacturing, marketing, financial and technical resources than we
have. We are uncertain whether we can continue to compete successfully or retain
market share.

IF WE FAIL TO ADEQUATELY RESPOND TO TECHNOLOGICAL CHANGES IN THE
TELECOMMUNICATIONS INDUSTRY, WE MAY LOSE MARKET SHARE.

     The telecommunications industry is in a period of rapid technological
evolution, marked by the introduction of competitive product and service
offerings, such as the utilization of the Internet for international voice and
data communications. We may fail to adequately respond to the technological
changes in the telecommunications industry and thus lose market share.

our competitors may challenge our competitive position or increase the amount of
expenditures that will be required for us to respond to a rapidly changing
technological environment.

IF WE CANNOT ATTRACT AND RETAIN QUALIFIED MANAGEMENT AND TECHNICAL PERSONNEL, WE
MAY FAIL TO SUCCESSFULLY OPERATE OUR BUSINESS.

     We are highly dependent on the services of several key executive officers
and technical employees, particularly John D. Phillips, World Access' Chief
Executive Officer, and Walter J. Burmeister, World Access' President. In
addition, we will need to hire additional skilled personnel to support the
continued growth of our business. The market for skilled personnel, especially
those with the technical abilities we require, is currently very competitive,
and we must compete with much larger companies with significantly greater
resources to attract and retain these persons. If we are unable to retain the
services of Mr. Phillips, Mr. Burmeister, and other key management and technical
personnel or to attract such personnel in the future, we may not be able to
successfully operate our business.

GOVERNMENT REGULATORY POLICIES AND INDUSTRY CONSOLIDATION IN EUROPE MAY DECREASE
PROFIT MARGINS AND INCREASE PRICING PRESSURES IN OUR INDUSTRY AND DECREASE
DEMAND FOR OUR SERVICES AND PRODUCTS.

     We 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 our services and products that
support these services. Lower prices may affect the cost effectiveness of our
deployment of public network services. User uncertainty regarding future
policies may also decrease demand for our telecommunications products and
services.

OUR 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, we intend to
increase our international sales. Our 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;

     - difficulty in accounts receivable collection;

     - potentially adverse tax consequences of international tax laws;

     - dependence on foreign partners; and

     - fluctuations in foreign currency values.

WE MAY FACE LIABILITY UNDER THE FOREIGN CORRUPT PRACTICES ACT.

     Our international operations are subject to the Foreign Corrupt Practices
Act, which generally prohibits U.S. companies and their intermediaries from
bribing foreign officials for the purpose of obtaining or keeping business. We
may face liability under the Foreign Corrupt Practices Act as a result of past
or future actions taken without our knowledge by our agents, strategic partners
and other intermediaries.

WE MAY NOT BE ABLE TO LEASE TRANSMISSION FACILITIES AT HISTORICAL RATES.

     Our future profitability will be based in part upon our 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. As a result of the mergers, we will be able to utilize World Access'
network facilities, STAR's network facilities and WORLDxCHANGE's network
facilities. However, our experience in providing data transmission services to
date has been limited and, consequently, we can provide no assurance that we
will be successful in the data transmission business. Our ability to
successfully enter the data transmission business will depend upon, among other
things, our ability to:

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

     - hire and train qualified personnel; and

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

     If we are not successful, there may be a material adverse effect on our
business, financial condition and operations. Also, a substantial portion our
transmission capacity is obtained on a variable, per minute and short-term
basis, subjecting us to the possibility of unanticipated price increases and
service cancellations. Since we 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, our gross margins are
subject to significant fluctuations. Competitive pricing pressures for these
facilities may also negatively impact us in the longer term. In providing these
services, we will be dependent upon vendors for assistance in the planning and
deployment of our data product offerings, as well as ongoing training and
support. In Europe, there are a number of different protocols for data
transmission. Our network will need to be able to handle all of these protocols,
which will pose technical difficulties.

DELAYS AND INCONSISTENCIES IN IMPLEMENTATION OF THE WORLD TRADE ORGANIZATION
AGREEMENT AND OTHER COMPETITIVE DIRECTIVES MAY ADVERSELY AFFECT OUR BUSINESS 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. Our ability to expand our operations
internationally will be limited if any signatory country to the World Trade
Organization Agreement fails to implement its obligations on a timely basis.
These factors and other obstacles which could develop in connection with the
deregulation of telecommunications services could have a material adverse effect
on our operations by slowing down our rate of expansion.

     The national governments of the European Union member states in which we
currently operate, and in which we may operate in the future, 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. In certain cases this has been
done on an inconsistent, and sometimes unclear, basis. In addition, 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 other obstacles which

                                       46
<PAGE>   60

could develop in connection with deregulation of telecommunications services
could have a material adverse effect on our operations by slowing down the rate
of our expansion.

WE CANNOT ASSURE YOU THAT OUR PLANNED ENTRY INTO THE INTERNET AND DATA BUSINESS
IN EUROPE WILL BE SUCCESSFUL.

     The market for Internet connectivity and related services is extremely
competitive. Our primary competitors will include other Internet service
providers, or ISPs, that have a significant national or international presence.
Many of these carriers have substantially greater resources, capital and
operational experience than we do. We also expect we will experience increased
competition from traditional telecommunications carriers that expand into the
market for Internet services. In addition, we will require substantial
additional capital to make investments in our Internet operations, and we may
not be able to obtain that capital on favorable terms or at all.

     Even if we are able to establish and expand our Internet business, we will
face numerous risks that may adversely affect the operations of our Internet
business. These risks include:

     - competition in the market for Internet services;

     - our limited operating history as an ISP;

     - our ability to adapt and react to rapid changes in technology related to
       our Internet business;

     - uncertainty relating to the continuation of the adoption of the Internet
       as a medium of commerce and communications;

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

     - adverse regulatory developments;

     - potential liability for information disseminated over our network; and

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

AS WE EXPAND OUR FOCUS ON RETAIL CUSTOMERS AND EMERGING CARRIERS, OUR LEVEL OF
UNCOLLECTIBLE DEBT MAY INCREASE.

     As a wholesale provider of international long distance services, we will
depend upon traffic from other long distance providers, and upon the collection
of receivables from these customers. If we experience difficulties in the
collection of our accounts receivable from our major customers, our cash flow
may be substantially reduced. In addition, we may expend considerable resources
to collect receivables from customers who fail to make timely payments.

     In our experience, a large percentage of the revenues generated by retail
customers and from emerging carriers is uncollectible. Therefore, if the
percentage of our revenues derived from retail operations and from sales to
emerging carriers increases, our level of uncollectible debt is likely to
increase.

WORLD ACCESS' CERTIFICATE OF INCORPORATION AND BYLAWS COULD MAKE IT LESS LIKELY
THAT ITS STOCKHOLDERS RECEIVE A PREMIUM FOR THEIR SHARES IN AN UNSOLICITED
TAKEOVER ATTEMPT.

     If World Access stockholders do not approve Proposals 4 and 5 in this joint
proxy statement/ prospectus, some provisions of World Access' amended
certificate of incorporation and its bylaws could discourage unsolicited
acquisition proposals or delay or prevent a change in control resulting in its
stockholders receiving a lower premium for their shares in any such attempt or
in our market price per share and the voting and other rights of its
stockholders being adversely affected. Currently, those provisions include a
classified board of directors, a prohibition on written consents in lieu of
meetings of

                                       47
<PAGE>   61

the stockholders and the authorization to issue up to 150,000,000 shares of
common stock and up to 10,000,000 shares of preferred stock, with the board
having the authority to designate the rights, preferences and limitations of the
preferred stock.

TERMINATION OF WORLD ACCESS' CARRIER SERVICE AGREEMENT WITH WORLDCOM NETWORK
SERVICES COULD MATERIALLY ADVERSELY AFFECT OUR REVENUES.

     World Access entered into a Carrier Service Agreement with WorldCom Network
Services, Inc., a wholly-owned subsidiary of MCI WorldCom, under which WorldCom
Network Services purchases international long distance services from us on a
wholesale basis. WorldCom Network Services presently provides a significant
portion of our service revenues. Termination of the service agreement, or any
reduction in the services provided, could materially decrease our revenues.
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. Revenues attributable to the Service Agreement for 1999
comprised approximately 53.4% of total 1999 revenues of World Access for this
period.

TECHNICAL DIFFICULTIES WITH OR FAILURES IN OUR TELECOMMUNICATIONS NETWORK COULD
RESULT IN DISSATISFIED CUSTOMERS AND LOST REVENUE.

     Technical difficulties with or failures in our telecommunications network
could result in dissatisfied customers and lost revenue. For example, a failure
in a portion of our network could prevent us from delivering telephone calls
initiated by our customers. Additionally, technical difficulties with the
network could cause the loss of call detail record information, which is the
basis for our ability to process and substantiate customer billings. Components
of our networks have failed in the past which have had a material adverse effect
on our operating results. There can be no assurance that similar or other
failures will not occur in the future.

THE GROWTH OF OUR TELECOMMUNICATIONS NETWORK WILL BE COSTLY, AND WE MAY NOT BE
ABLE TO INCREASE OUR NETWORK CAPACITY AT A RATE THAT IS COMMENSURATE WITH THE
DEMANDS OF OUR CUSTOMER BASE.

     We are currently in the process of expanding our network, and as we expand
our network and the volume of our network traffic, our 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 our operating
margins may decrease. If our traffic volume were to decrease, or fail to
increase to the extent expected or necessary to make efficient use of our
network, our costs as a percentage of revenues would increase significantly,
which could have a material adverse effect on our business, financial condition
or results of operations.

     In addition, our business depends in part on our ability to obtain
transmission facilities on a cost-effective basis. We may not be able to obtain
sufficient transmission facilities or access to undersea fiber optic cable on
economically viable terms. Our failure to obtain telecommunications facilities
that are sufficient to support our network traffic in a manner that ensures the
reliability and quality of our telecommunications services could have a material
adverse effect on our business, financial condition or results of operations.
Undersea fiber optic cables typically take several years to plan and construct,
and carriers generally make investments well in advance, based on a forecast of
anticipated traffic. Therefore, our operations are subject to the risk that we
will not adequately anticipate the amount of traffic over our network and may
not procure sufficient cable capacity or network equipment in order to ensure
the cost-effective transmission of customer traffic. We do not control the
construction of these facilities and must obtain access to these facilities
through partial ownership positions. If ownership positions are not available,
we must obtain access to these facilities through lease arrangements on
negotiated terms that may vary with industry and market conditions.

                                       48

FOREIGN GOVERNMENTS MAY ATTEMPT TO PREVENT US FROM CONDUCTING OUR BUSINESS.

     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 our competitors or companies, such as
national telephone companies, upon which we and our foreign partners may depend
for required interconnections to local telephone networks and other services.
Accordingly, government actions in the future could have a material adverse
effect on our operations. In highly regulated countries in which we are not
dealing directly with the dominant local exchange carrier, the dominant carrier
may have the ability to route service to our foreign partner and, if this
occurs, we may not receive the revenues from the services and have limited or no
recourse. In countries where competition is not yet fully established and we are
dealing with an alternative operator, foreign laws may prohibit or impede new
operators from offering services in these markets.

     We currently plan to expand our foreign operations as these markets
increasingly permit competition. The nature, extent and timing of our 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
us with practical opportunities to compete in the near future, or at all, and we
may not be able to take advantage of any such liberalization in a timely manner.

RECENT FEDERAL COMMUNICATIONS COMMISSION ACTIONS MAY ADVERSELY AFFECT US BY
INCREASING COMPETITION, WHICH MAY INCREASE PRICING PRESSURES AND DECREASE DEMAND
FOR OUR SERVICES.

     Recent FCC 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 FCC'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 our margins and decrease demand for our services.

FCC INTERVENTION REGARDING THE SETTLEMENT RATES CHARGED BY FOREIGN CARRIERS MAY
DISRUPT OUR TRANSMISSION ARRANGEMENTS TO CERTAIN COUNTRIES.

     The FCC 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 FCC's benchmarks order was recently upheld by the U.S. Court of
Appeals for the District of Columbia circuit. The FCC's action may reduce our
settlement costs, although the costs of other U.S. international carriers also
may be reduced in a similar fashion. The FCC 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 FCC
intervention could disrupt our transmission arrangements to certain countries or
require us to modify our existing arrangements.

A RECENT FCC ORDER MAY ADVERSELY AFFECT OUR ABILITY TO COMPETITIVELY PRICE OUR
SERVICE OFFERINGS.

The Telecommunications Act of 1996 permits the FCC to forbear enforcement of the
tariff provisions in such act, which apply to all interstate and international
carriers, and the U.S. Court of Appeals for the District of Columbia Circuit
recently upheld an FCC order directing all domestic interstate carriers to de-
tariff their offerings. The FCC's order only applies to domestic services.
However, the FCC may forbear its current tariff rules for U.S. international
carriers such as us, or order these carriers to de-tariff their services. Any
such FCC action would likely afford non-dominant international carriers greater
flexibility in pricing service offerings, which would increase our competition.
The FCC routinely reviews the contribution rate for various levels of regulatory
fees, including the rate for fees levied to support universal

                                       49
<PAGE>   63

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 FCC.

OUR FAILURE TO COMPLY WITH STATE REGULATIONS COULD RESULT IN PENALTIES,
INCLUDING REVOCATION OF ONE OF OUR CERTIFICATES OF AUTHORITY.

     Various state laws and regulations impose prior certification,
notification, registration, tariff and/or other requirements on our intrastate
long distance telecommunications operations and our subsidiaries. The vast
majority of states require that we and our subsidiaries apply for certification
to provide intrastate telecommunications services. In most jurisdictions, we
also must file and obtain prior regulatory approval of tariffs for intrastate
services. State regulatory authorities can generally condition, modify or revoke
certificates of authority or impose fines and other penalties for failure to
comply with state laws and regulations.

REGULATION OF CUSTOMERS MAY MATERIALLY ADVERSELY AFFECT OUR REVENUES BY
DECREASING THE VOLUME OF TRAFFIC WE RECEIVE FROM MAJOR CUSTOMERS.

     Our customers are also subject to actions taken by domestic or foreign
regulatory authorities that may affect the ability of customers to deliver
traffic to us. Regulatory sanctions have been imposed on certain of our
customers in the past. Future regulatory actions could materially adversely
affect the volume of traffic received from a major customer, which could
materially decrease our revenues.

DELAYS AND COSTS INCURRED IN ACHIEVING COMPLIANCE WITH GOVERNMENT REGULATIONS
AND EVOLVING INDUSTRY STANDARDS FOR OUR PRODUCTS COULD ADVERSELY AFFECT OUR
REVENUES.

     Our products' failure to comply with the various existing and evolving
regulations and industry standards or the delays and costs incurred in achieving
compliance with these regulations and standards could materially decrease our
revenues, increase our costs and reduce our profitability. Our 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 FCC, as well as with standards established by Bell
Communications Research. Internationally, our products and services must comply
with standards established by telecommunications authorities in various
countries, as well as with recommendations of the International
Telecommunications Union.

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

     Any system or network failure that interrupts our operations could have a
material adverse effect on our business, financial condition or results of
operations. Our operations are dependent on our ability to successfully expand
our network and integrate new and emerging technologies and equipment into our
network, which are likely to increase the risk of system failure and to cause
strain upon the networks. Our operations also depend on our ability to protect
our 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. We cannot be certain that our 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 our
relationships with our customers and our business, operating results and
financial condition.

RISK FACTORS CONCERNING WORLD ACCESS COMMON STOCK

THE PRICE OF WORLD ACCESS COMMON STOCK HAS BEEN VOLATILE AND COULD CONTINUE TO
FLUCTUATE SUBSTANTIALLY.

     World Access common stock is traded on the Nasdaq National Market. The
market price of World Access common stock has been volatile and could fluctuate
substantially based on a variety of factors, including the following:

     - announcements of new products or technological innovations by us or
       others;

     - variations in our results of operations;

     - individual sales of large amounts of shares;

     - the gain or loss of significant customers;

     - the timing of acquisitions of businesses or technology licenses;

     - the issuance by World Access of significant amounts of common stock in
       connection with acquisitions or otherwise;

     - legislative or regulatory changes;

     - general trends in the industry;

     - market conditions; and

     - analysts' estimates and other events in our industry.

     In addition, the stock market has experienced extreme price and volume
fluctuations that have particularly affected the market price for many
technology companies and that have often been unrelated to the operating
performance of these companies. These broad market fluctuations may adversely
affect the market price of World Access common stock.

SIGNIFICANT VARIANCE IN OUR QUARTERLY OPERATING RESULTS COULD ADVERSELY AFFECT
THE PRICE OF WORLD ACCESS COMMON STOCK.

     In future quarters, our results of operations may fail to meet the
expectations of market analysts and investors, which may adversely affect the
price of our common stock. World Access quarterly operating results have varied
significantly in the past and 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. Our 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;

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

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

     Our 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 our 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 our sales incentive plans; and

                                       51
<PAGE>   65

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

     In addition, our operating results can vary due to factors such as:

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

     - our loss of favorable routing options;

     - 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 our expansion in international and retail
       markets; and

     - general domestic and international economic and political conditions.

     Further, we obtain a substantial portion of our transmission capacity on a
variable, per minute and short-term basis; therefore, we may experience
unanticipated price increases and service cancellations. Since we do 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, our gross margins may also fluctuate significantly over short periods of
time.

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

     Accordingly, we believe that you should not rely upon period-to-period
comparisons of our operating results as an indication of our 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.

     Matters to be considered.  At the World Access special meeting,
stockholders of record of World Access as of the close of business on the World
Access record date will be asked to consider and vote upon the following
proposals:

     - Proposal 1. To approve and adopt the STAR merger agreement and the
       transactions contemplated thereby. Under the STAR merger agreement, (i)
       each outstanding share of STAR common stock will be converted into the
       right to receive, at the election of World Access, (a) 0.3905 shares of
       World Access common stock, subject to adjustment, also referred to as the
       exchange ratio, or (b) that number of shares of World Access common stock
       equal to 60% of the exchange ratio and 40% of the sum of 7.81 plus the
       net cash proceeds in excess of $150.0 million received by STAR upon the
       sale of its subsidiary, PT-1 Communications, Inc., divided by 62,856,702;
       and (ii) STAR will become a wholly-owned subsidiary of World Access;

     - Proposal 3. To approve and adopt the WORLDxCHANGE merger agreement and
       the transactions contemplated thereby. Under the WORLDxCHANGE merger
       agreement, (i) each outstanding share of WORLDxCHANGE common stock
       (including shares of preferred stock deemed to be automatically converted
       into common stock) will be converted into the right to receive 0.6583
       shares of World Access common stock; and (ii) WORLDxCHANGE will become a
       wholly-owned subsidiary of World Access;

     - Proposal 4. To approve an amendment to Article IV of World Access'
       amended certificate of incorporation to increase the number of shares of
       common stock that World Access is authorized to issue from 150,000,000
       shares to 290,000,000 shares;

     - Proposal 5. To approve an amendment to Article IX of World Access'
       amended certificate of incorporation to increase the number of authorized
       directors from 12 to 15 and to end the division of World Access' board of
       directors into three classes so that all directors will serve terms of
       one year or until their successors are duly elected and qualified or
       until their earlier resignation or removal;

     - Proposal 6. To approve an amendment to World Access' Directors' Warrant
       Incentive Plan to increase the number of warrants issuable under the
       Directors' Warrant Incentive Plan from 600,000 warrants to 1,200,000
       warrants and to modify the performance criteria of World Access common
       stock under the plan;

     - Proposal 7. To elect as directors the two nominees named herein to serve
       (i) if Proposal 5 is approved, for a term of one year and until their
       successors are duly elected and qualified or until their earlier
       resignation or removal or (ii) if Proposal 5 is not approved, for a term
       of three years and until their successors are elected and qualified or
       until their earlier resignation or removal; and

     - to transact such other business as may properly come before the World
       Access special meeting or any adjournments or postponements thereof.

     The stockholders of record of the World Access Series C preferred stock
will not be entitled to consider and vote upon Proposal 7.

     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.
Approval of Proposal 4 by the World Access stockholders to increase the number
of shares of common stock World Access is authorized to issue is required for
World Access to have sufficient authorized shares to complete both mergers.

     World Access board of directors' recommendations.  The board of directors
of World Access unanimously approved the STAR merger agreement, the WORLDxCHANGE
merger agreement and the transactions contemplated thereby and unanimously
recommends that the stockholders of World Access vote FOR the approval and
adoption of the STAR merger agreement and the WORLDxCHANGE merger agreement and
the transactions contemplated thereby.

     In addition, the board of directors of World Access unanimously approved,
recommended and declared advisable the amendments to the World Access amended
certificate of incorporation to increase the number of shares of common stock
World Access has the authority to issue, increase the maximum number of
authorized World Access directors and eliminate the classification of the World
Access board of directors. The board also recommends a vote for the amendment to
the World Access Directors' Warrant Incentive Plan to increase the number of
warrants issuable under the Directors' Warrant Incentive Plan from 600,000 to
1,200,000 and for the nominees for director described in this joint proxy
statement/prospectus.

     World Access record date.  The board of directors of World Access has fixed
               , 2000 as the record date for determination of holders of World
Access voting stock entitled to notice of, and to vote at, the World Access
special meeting.

     Stockholders entitled to vote.  As of the close of business on the record
date,                shares of World Access common stock were outstanding, held
by approximately                holders of record. World Access stockholders are
entitled to cast one vote per share of World Access common stock owned or to be
received upon the conversion of shares of preferred stock owned as of the World
Access record date.

     World Access has 50,000 shares of Series A preferred stock issued and
outstanding. Each share of Series A preferred stock is convertible at the option
of the holder into World Access common stock in accordance with a conversion
formula contained in the World Access amended certificate of incorporation. The
Series A preferred stock is entitled to vote on the approval and adoption of the
proposals to be considered at the special meeting on an as converted basis with
the World Access common stock voting together as a single class. Therefore, the
holders of the Series A preferred stock may vote with the holders of World
Access common stock on the proposals described herein as if they held 4,347,826
shares of World Access common stock.

     World Access also has 350,259.875 shares of Series C preferred stock issued
and outstanding. Each share of Series C preferred stock is convertible at the
option of the holder into World Access common stock in accordance with a
conversion formula contained in the World Access amended certificate of
incorporation. Except with respect to the election of directors, the Series C
preferred stock is entitled to vote on the approval and adoption of the
proposals to be considered at the special meeting on an as converted basis with
the World Access common stock voting together as a single class. Therefore, the
holders of the Series C preferred stock may vote with the holders of World
Access common stock on the proposals described herein (except with respect to
the election of directors) as if they held 17,186,451 shares of World Access
common stock.

     World Access also has 184,000 shares of Series D preferred stock issued and
outstanding. Each share of Series D preferred stock is convertible at the option
of the holder into World Access common stock in accordance with a conversion
formula contained in the World Access amended certificate of incorporation. The
Series D preferred stock is entitled to vote on the approval and adoption of the
proposals to be considered at the special meeting on an as converted basis with
the World Access common stock voting together as a single class. Therefore, the
holders of the Series D preferred stock may vote with the holders of World
Access common stock on the proposals described herein as if they held 10,222,222
shares of World Access common stock.

     Only holders of record of World Access voting stock as of the close of
business on the World Access record date are entitled to notice of and to vote
at the World Access special meeting and any adjournments or postponements
thereof.

                                       54
<PAGE>   68

     Quorum; vote required.  Each holder of record of World Access common stock
on the World Access record date is entitled to cast one vote for each share of
World Access common stock held thereby. A majority of the shares of World Access
common stock entitled to vote at the World Access special meeting will
constitute a quorum for the transaction of business at the World Access special
meeting. The election of the nominees for director will require the affirmative
vote of a 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.
Pursuant to the World Access amended certificate of incorporation, the
stockholders of record of the World Access Series C preferred stock will not be
entitled to consider and vote upon the election of the nominees for director.
The approval and adoption of the STAR merger agreement and the transactions
contemplated thereby and the WORLDxCHANGE merger agreement and the transactions
contemplated thereby, the approval of the amendment to the World Access
Directors' Warrant Incentive Plan to increase the number of warrants issuable
under the Directors' Warrant Incentive Plan and the approval of the amendment to
the World Access amended certificate of incorporation to increase the number of
shares of common stock World Access is authorized to issue will require the
affirmative vote of a majority in voting power of the shares of World Access
voting stock entitled to vote and voting as a single class. The approval of the
amendment to the World Access amended certificate of incorporation to increase
the number of shares of common stock World Access is authorized to issue will
also require the affirmative vote of a majority of the shares of World Access
common stock entitled to vote and voting as a single class. The approval of the
amendment to the World Access amended certificate of incorporation to increase
the maximum number of authorized directors and to eliminate the classification
of the World Access board of directors will require the affirmative vote of at
least 75% in voting power of the shares of World Access voting stock entitled to
vote and voting as a single class. 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

fiduciaries for forwarding of proxy solicitation materials to beneficial owners
of shares held of record by such custodians, nominees and fiduciaries, and World

        statement/prospectus, including STAR's receipt of a sales price of at
        least $           , obtaining the opinion of STAR's financial advisor as
        to the fairness from a financial point of view of the consideration to
        be received in the sale and approval by the STAR board of directors of a
        definitive sale agreement containing terms that the STAR board of
        directors determines to be in the best interests of STAR; and

     -  To transact any other business that is properly brought before the STAR
        special meeting, or any adjournment or postponement of the STAR special

     STAR board of directors' recommendations.  The board of directors of STAR
approved the STAR merger agreement, the transactions contemplated by the STAR
merger agreement and the PT-1 sale, including either the sale of PT-1 to PT-1
acquiror pursuant to the terms of PT-1 letter of intent or to such other buyer
and on such terms as the STAR board of directors shall subsequently approve,
subject to the minimum requirements set forth in this joint proxy
statement/prospectus, including STAR's receipt of a sales price of at least $
          , obtaining the opinion of STAR's financial advisor in connection with
the sale and approval by the STAR board of directors of a definitive sale
agreement containing terms that the STAR board of directors determines to be in
the best interests of STAR, and recommends that the stockholders of STAR vote
FOR the approval and adoption of the STAR merger agreement, FOR the approval of
the PT-1 sale and FOR the approval of the transactions contemplated by the STAR
merger agreement and the PT-1 sale.

     STAR record date.  The board of directors of STAR has fixed             ,
2000 as the record date for determination of holders of STAR common stock
entitled to notice of and to vote at the STAR special meeting.

     Stockholders entitled to vote.  As of the close of business on the record

approximately                holders of record. Each share of outstanding STAR
common stock is entitled to one vote.

     Only holders of record of STAR common stock as of the close of business on
the STAR record date are entitled to notice of and to vote at the special

majority of the outstanding shares of STAR common stock.

     Shares of STAR common stock that are voted "FOR," "AGAINST" or "WITHHELD"

the STAR special meeting and entitled to vote on the subject matter. Abstentions

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

particular proposal on which the broker has expressly not voted. Because
adoption and approval of the STAR merger agreement, the PT-1 sale, and the
transactions contemplated by the STAR merger agreement and the PT-1 sale,
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

                                   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 the consideration of
the World Access stockholders and the STAR stockholders, voting separately.
While we believe that the description covers the material terms of the STAR
merger and the related transactions, this summary may not contain all of the
information that is important to you. You should carefully read this entire
document and the other documents we refer to for a more complete understanding
of the STAR merger.

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, significant capital costs were being incurred in connection with the
expansion of STAR's business into Germany and the development of its retail long
distance operations. During this time period, Goldman Sachs Credit Partners LP,
Kaufman Brothers, Lehman Brothers, Morgan Stanley Dean Witter and Deutsche Bank
Securities Inc. were retained to pursue a possible high yield bond offering and
to provide financial advice on potential transactions with strategic merger
partners. STAR ultimately concluded that a high yield bond offering would not be
an effective means of raising necessary capital.

     During this same period, STAR also consulted with each of Goldman Sachs,
Kaufman Brothers, 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. Market conditions in the telecommunications business and the capital
position of STAR made such contemplated transactions infeasible.

     STAR received several acquisition proposals in the last quarter of 1999,
but each proposal was limited to the acquisition of STAR's German operations.
These proposals were not considered attractive by the STAR board of directors as
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 overall 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 as STAR was subject to a prior
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 whereby World Access proposed to 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 infuse cash in the
form of a bridge loan upon the signing of a definitive agreement. During the due
diligence period contemplated by the letter of intent, World Access discovered
that for a variety of reasons, STAR would require significant, near term capital
infusion. As a result of this unexpected need by STAR for capital, World Access
and STAR representatives met to renegotiate the terms of the merger in light of
STAR's capital requirements. On February 2, 2000, the parties agreed to a
repricing of the 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 and agreed to provide STAR with significant interim financing. Based on
this agreement, the parties issued a joint press release announcing the
repricing and proceeded to finalize the 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

                                       59
<PAGE>   73

shortage and the unavailability of superior offers, management was instructed to
continue negotiations with World Access.

     On February 8, 2000, the board of directors of World Access met by
telephonic conference call 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 again
met by telephonic conference call 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, DLJ
gave its oral opinion as to the fairness of the consideration to be paid by
World Access pursuant to the STAR merger agreement. The board of directors also
received summaries of the results of World Access' due diligence investigation
of STAR. After the foregoing, the World Access board of directors unanimously
approved the STAR merger agreement and the transactions contemplated thereby and
unanimously agreed to recommend its adoption to the stockholders of World
Access. On February 11, 2000, DLJ forwarded its written opinion regarding the
fairness of the consideration to be paid by World Access pursuant to 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 with respect to 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 the current financial
condition of STAR, the decline in margins in its core business due to increased
competition and the significant capital required to accomplish management's
program of diversification. The STAR board of directors voted to approve the
STAR merger agreement and the transactions contemplated thereby and voted to
recommend that the stockholders of STAR vote for the approval and adoption of
the STAR merger agreement and the transactions contemplated thereby. In
approving the STAR merger, the STAR board of directors considered the potential
benefits of the merger, including relevant business, financial, legal and market
factors, some of which are discussed below under the heading "STAR's reasons for
the STAR merger."

WORLD ACCESS' REASONS FOR THE STAR MERGER

     The World Access board of directors believes that the STAR merger is fair
to and in the best interests of World Access and its stockholders. After
consideration of relevant business, financial, legal and market factors, the
board of directors unanimously approved the STAR merger agreement and the
transactions contemplated thereby and voted to recommend that the stockholders
of World Access vote FOR the approval and adoption of the STAR merger agreement
and the transactions contemplated thereby.

     In deciding to approve the STAR merger agreement and to recommend approval
and adoption of the STAR merger agreement by the World Access stockholders, the
World Access board of directors considered a number of factors, including
particularly the factors listed 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 specific 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
                                       60
<PAGE>   74

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 thereby based on its consideration of these
factors without taking into account the WORLDxCHANGE merger. The board of
directors 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. The directors also considered their own knowledge of World Access and
STAR and their respective businesses.

     STAR's extensive facilities-based network.  The World Access board of
directors considered STAR's strong international network presence, which
connects more than 51 countries worldwide and includes 24 international gateway
switches, 17 transoceanic cable systems, a North American fiber network
connecting 30 cities and ownership in a planned German fiber optic network
connecting approximately 23 German cities.

     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 also
considered the importance of market position in the global telecommunications
services industry. The World Access board of directors considered the potential
significant cost savings to be achieved as a result of the STAR merger in
providing global retail telecommunications services at competitive rates.

     STAR's established customer base.  The World Access board of directors
considered the compatibility of STAR's established base of wholesale customers
with World Access' existing customer base. STAR's customer base includes 14 of
the top 40 global carriers, and STAR was the first carrier in the emerging
carrier marketplace to be selected by AT&T for overflow capacity.

     Ability to accelerate plans to become a leading provider of bundled voice,
data and internet services to key international 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 of directors 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.

RECOMMENDATION OF THE WORLD ACCESS BOARD OF DIRECTORS

     The World Access board of directors has carefully 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 BOARD OF DIRECTORS OF WORLD
ACCESS HAS UNANIMOUSLY APPROVED THE STAR MERGER AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY AND UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF WORLD
ACCESS VOTE FOR THE APPROVAL AND ADOPTION OF THE STAR MERGER AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED THEREBY.

STAR'S REASONS FOR THE STAR MERGER

     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 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 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 relevant
business, financial, legal and market factors, some of which are discussed
below.

                                       61
<PAGE>   75

     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 a number of factors, including the following:

     The potential cost savings and synergies.  The STAR board of directors
considered the potential cost savings and synergies that would be achieved by
the combination of World Access and STAR. Among the benefits from integration
that the STAR board of directors considered were the potential financial and
operating efficiencies and other synergies that would result from integrating
the systems and operations of both companies. In addition, the STAR board of
directors considered the enhanced capabilities that the combined management team
would provide to STAR's operations.

     Diversified geographic and product market position.  The STAR board of
directors considered the complementary geographic network coverage of each
company and the enhanced European presence that would be obtained by the
integration of STAR's network assets and licenses in Germany with World Access'
existing European operations. The board of directors' analysis included the
potential positioning of the combined company as a leading provider of global
telecommunications services with a state-of-the art pan-European network in 14
Western European countries and ownership positions in 26 international fiber
optic cable networks.

     The financial condition of STAR.  The STAR board of directors examined the
current financial condition of STAR and considered the potential benefits of a
sale transaction to a company with greater financial resources than that of
STAR. The STAR board of directors was particularly concerned about the current
debt load of STAR and its weak capital position. The STAR board of directors
considered the availability of interim financing in connection with the STAR
merger and the lack of a superior offer prior to the approval of the STAR merger
agreement.

     The foregoing discussion of the information and factors considered by the
STAR board of directors is not intended to be exhaustive. In view of the wide
variety of factors considered in connection with its evaluation of the STAR
merger agreement and the STAR merger, the STAR board of directors did not find
it practical to, nor did it attempt to, quantify, rank or otherwise attempt to
assign relative weights to the specific factors considered in reaching its
determination. In addition, the STAR board of directors did not undertake to
make a specific determination as to whether any particular factor was favorable
or unfavorable to the board of directors, or assign any particular weight to any
factor, but rather conducted an overall analysis of the factors described above,
including thorough discussion with and questioning of STAR's management and
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.

RECOMMENDATION OF THE STAR BOARD OF DIRECTORS

     The STAR board of directors has 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 HAS
APPROVED THE STAR MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THE STAR
MERGER AGREEMENT AND RECOMMENDS THAT THE STOCKHOLDERS OF STAR VOTE FOR THE
APPROVAL AND ADOPTION OF THE STAR MERGER AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY.

OPINION OF WORLD ACCESS' FINANCIAL ADVISOR REGARDING THE STAR MERGER

     The board of directors of World Access engaged Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ") to act as its financial advisor in connection
with the STAR merger. On February 11, 2000, DLJ 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

                                       62
<PAGE>   76

of view. As described above under "World Access' reasons for the STAR merger,"
DLJ's opinion was only one of many factors taken into consideration by the board
of directors of World Access in making its determination to approve the STAR
merger agreement.

     THE FULL TEXT OF DLJ'S OPINION IS INCLUDED AS ANNEX C TO THIS JOINT PROXY
STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. STOCKHOLDERS ARE
URGED TO READ CAREFULLY DLJ'S OPINION IN ITS ENTIRETY FOR THE DESCRIPTIONS OF
THE PROCEDURES FOLLOWED, ASSUMPTIONS MADE, OTHER MATTERS CONSIDERED AND
LIMITATIONS OF THE REVIEW UNDERTAKEN IN ARRIVING AT THE OPINION. DLJ'S OPINION
WAS PREPARED FOR AND ADDRESSED TO WORLD ACCESS' BOARD OF DIRECTORS AND ONLY
ADDRESSES THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE CONSIDERATION TO
BE PAID BY WORLD ACCESS. DLJ'S OPINION DOES NOT:

          (1) ADDRESS THE MERITS OF THE UNDERLYING DECISION BY WORLD ACCESS TO
              ENGAGE IN THE STAR MERGER OR OTHER BUSINESS STRATEGIES CONSIDERED
              BY WORLD ACCESS;

          (2) CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW THAT
              STOCKHOLDER SHOULD VOTE AT THE STOCKHOLDERS' MEETING; OR

          (3) CONSTITUTE AN OPINION AS TO THE PRICE AT WHICH WORLD ACCESS COMMON
              STOCK WILL ACTUALLY TRADE AT ANY TIME.

     The type and amount of consideration was determined in arms-length
negotiations between World Access and STAR. No restrictions or limitations were
imposed by World Access upon DLJ with respect to the investigations made or the
procedures followed by DLJ in rendering its opinion.

     In arriving at its opinion, DLJ, among other things:

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

     - compared selected 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 DLJ deemed appropriate for purposes of its
       opinion.

     In rendering its opinion, DLJ 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. DLJ
relied upon the estimates of the management of World Access of the operating
synergies achievable as a result of the STAR merger. DLJ 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, DLJ relied upon and
assumed net cash proceeds of $150.0 million from the sale of PT-1 by STAR. DLJ
expressed no opinion with respect to such forecasts or the assumptions on which
they were based, and DLJ 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
DLJ. DLJ 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. DLJ assumed that the STAR merger would be accounted for as a pooling of
interests under generally accepted accounting principles and that it would
qualify as a tax-free reorganization for U.S. federal income tax purposes.

     The preparation of a fairness opinion is a complex process that is not
necessarily susceptible to partial analysis or summary description and involves
determinations about the most appropriate and relevant methods of financial
analysis and the application of these methods to the particular circumstances.
DLJ performed each of the analyses summarized below in order to provide a
different perspective on the STAR merger and add to the total mix of information
available. However, although the separate analyses are summarized below, DLJ
believes that its analyses must be considered as a whole. Selecting portions of
the analyses or of the summary set forth below, without considering the analyses
as a whole, could create an incomplete or misleading view of the processes
underlying DLJ's opinion. DLJ 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 and did not attempt to
assign specific weights to particular analyses or factors considered. Rather, in
arriving at its opinion, DLJ considered the results of each of these analyses
together, in their totality and in light of each of the other analyses and made
qualitative judgements as to the significance and relevance of all of the
factors and analyses considered in arriving at its opinion.

     In performing its analyses, DLJ made numerous assumptions with respect to
industry performance, business and regulatory, financial, economic, monetary,
political and market conditions and other matters, many of which are beyond the
control of World Access or STAR. In addition, analyses relating to the value of
businesses or securities are not appraisals and do not reflect the prices at
which the businesses or securities can actually be sold. Stockholders should
understand that no company or transaction used in DLJ's analyses as a comparison
is directly comparable to World Access or STAR or to the STAR merger. It should
also be understood that analyses based upon projections or forecasts of future
results are not necessarily indicative of actual future results, which may be
significantly more or less favorable than suggested by those analyses. Because
these analyses are inherently subject to uncertainty, being based upon numerous
factors or events beyond the control of the parties, none of World Access, STAR
or DLJ or any other person assumes responsibility if future results are
different from those forecast. See "Risk Factors" elsewhere in this joint proxy
statement/prospectus.

     DLJ's opinion is necessarily based upon economic, market, financial and
other conditions as they existed on, and on information available to DLJ as of,
the date of its opinion. It should be understood that, although subsequent
developments may affect its opinion, DLJ does not have any obligation to update,
revise or reaffirm its opinion as a result of changes in such conditions or
otherwise.

     The following is a brief summary of the principal analyses performed by DLJ
in connection with DLJ's opinion and included in its presentation to World
Access' board of directors. For purposes of the following analyses, DLJ (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 DLJ 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.

     Included in the discussion below are summaries of some of the statistical
information appearing in that discussion presented in a tabular format. While
these tables are presented for the purpose of clarity and ease of reference,
they are not substitutes for, and must be read along with, all of the
information appearing under the captions immediately preceding them as well as
all of the information set forth in this document.

1. CONSIDERATION PAID ANALYSIS

     DLJ 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, DLJ 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.

                                       64
<PAGE>   78

2. COMPARABLE COMPANY ANALYSIS

     To provide comparative market information, DLJ compared selected historical
and projected operating and financial ratios of STAR to the corresponding data
and ratios of selected publicly traded companies that operate businesses
reasonably similar to STAR.

     For purposes of these analyses, DLJ compared STAR relative to the following
five companies deemed by DLJ to be reasonably comparable to STAR:

<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>

     However, no other company utilized in DLJ's analysis of comparable publicly
traded companies is identical to World Access or STAR. Accordingly, this
analysis necessarily involves complex considerations and judgments concerning
differences in financial and operating characteristics of each of World Access
and STAR and other factors that could affect the public trading values of World
Access, STAR or any other comparable company included in this analysis.

     Historical financial information used with respect to the comparable
companies was as of the most recent financial statements publicly available for
each company as of February 9, 2000. DLJ examined certain publicly available
financial data of the comparable companies including enterprise value (defined
as market value of common equity plus book value of total debt and preferred
stock less cash) as multiples of the latest publicly available last quarter
annualized revenues, estimated 2000 revenues taken from various analysts
research reports, gross property, plant and equipment and net property, plant
and equipment.

     DLJ 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 at
February 9, 2000. In addition, DLJ compared the enterprise value of STAR to the
implied enterprise values obtained by the above mentioned ratios of the
comparable companies 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.

(1) In comparing the ratio of STAR's enterprise value to its last quarter
    annualized revenues, estimated 2000 revenues, gross property, plant and
    equipment and net property, plant and equipment to those of the comparable
    companies at February 9, 2000, DLJ also determined a reference range for the

                                       65
<PAGE>   79

    comparable companies. The reference range represents a tighter range of the
    ratios as deemed reasonable by DLJ for comparative purposes.
(2) Source of Projections:

        - IDT Corporation: Lazard Freres research report dated December 6, 1999;

        - Pacific Gateway Exchange, Inc.: Jefferies research report dated
          November 17, 1999;

        - PRIMUS Telecommunications Group, Incorporated: Jefferies research
          report dated December 1, 1999;

        - RSL Communications, Inc.: DLJ research report dated December 1, 1999;
          and

        - STAR: projections provided by World Access management.

     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 M&A TRANSACTIONS.

     DLJ reviewed selected mergers and acquisitions transactions of companies
that operate businesses reasonably similar to that of STAR. Of these selected
M&A transactions, the following mergers and acquisitions transactions were
deemed most relevant by DLJ:

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

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

     However, no company, transaction or business utilized in DLJ's analysis of
selected M&A transactions is identical to World Access, STAR or the STAR merger.
Accordingly, this analysis necessarily involves complex considerations and
judgments concerning differences in financial and operating characteristics of
companies and other factors that could affect the acquisition, public trading or
other values of the companies or transactions being analyzed.

     DLJ performed this analysis in order to compare STAR's ratios of the
implied transaction value to its last twelve months revenues, last quarter
annualized revenues and net property, plant and equipment to those of the
selected mergers and acquisitions transactions. In addition, DLJ compared the
transaction value of STAR to the implied transaction values obtained by the
above mentioned ratios of the selected mergers and acquisitions transactions and
STAR's last twelve months revenues, last quarter annualized revenues and net
property, plant and equipment.

* For purposes of this analysis, DLJ compared STAR's ratios of the implied
  transaction value to its last twelve months revenues, last quarter annualized
  revenues and net property, plant and equipment to those

                                       66
<PAGE>   80

  of the selected mergers and acquisitions transactions deemed most relevant by
  DLJ. In addition, DLJ compared the transaction value of STAR to the implied
  transaction values obtained by the above mentioned ratios of the selected
  mergers and acquisitions transactions deemed most relevant by DLJ and STAR's
  last twelve months revenues, last quarter annualized revenues and net
  property, plant and equipment.

     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, DLJ 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. DLJ 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. DLJ calculated EBITDA for
STAR. EBITDA is earnings before interest, taxes, depreciation and amortization
and other items. DLJ calculated the terminal value of STAR at the end of the
forecast period, by applying a range of estimated EBITDA multiples selected in
DLJ'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 DLJ's subjective estimate of the terminal values based on
management's projected EBITDA were then discounted to the present using a range
of discount rates selected in DLJ's subjective judgment.

                                ($ IN MILLIONS)

<TABLE>

Discount rates...............................  15.0% - 18.3%
Implied Total Enterprise Value...............  $507.6 - $662.4
STAR Enterprise Value........................  $619.7
</TABLE>

     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 is not a complete description of the analyses
performed by DLJ, but describes, in summary form, the principal elements of the
analyses made by DLJ in arriving at DLJ's opinion. The preparation of a fairness
opinion involves 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 summarized.

ENGAGEMENT LETTER

     World Access selected DLJ to render an opinion in connection with the STAR
merger based upon DLJ's qualifications, expertise and reputation, including the
fact that DLJ, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers

     Pursuant to the terms of an engagement letter dated January 12, 2000, World
Access agreed to pay DLJ a fee of $400,000 at the time that DLJ delivered to the
World Access board of directors its opinion,

                                       67
<PAGE>   81
irrespective of the conclusion reached in the opinion, and to pay DLJ 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 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 STAR, or otherwise.
In addition, World Access agreed to reimburse DLJ for all of its out-of-pocket
expenses, including the reasonable fees and expenses of counsel incurred by DLJ
in connection with its engagement, and to indemnify DLJ for liabilities and
expenses arising out of DLJ's engagement, including liabilities under federal
securities laws.

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

     DLJ provides a full range of financial, advisory and brokerage services and
in the course of its normal trading activities may from time to time effect
transactions and hold positions in the securities or debt of World Access and/or
STAR for its own account and for the accounts of its customers. DLJ has
performed investment banking and other services for World Access in the past and
has been compensated for such services. DLJ acted as financial advisor to World
Access in connection with its acquisition of FaciliCom International, Inc., and
acted as solicitation agent in connection with the consent solicitation for
FaciliCom's outstanding senior notes. DLJ is currently acting as financial
advisor to World Access in connection with the WORLDxCHANGE merger.

OPINION OF STAR'S FINANCIAL ADVISOR REGARDING THE STAR MERGER

     Deutsche Bank Securities Inc. has 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 WRITTEN OPINION, DATED FEBRUARY 7, 2000,
WHICH SETS FORTH, AMONG OTHER THINGS, THE ASSUMPTIONS MADE, MATTERS CONSIDERED
AND LIMITS ON THE REVIEW UNDERTAKEN BY DEUTSCHE BANK IN CONNECTION WITH THE
OPINION, IS ATTACHED AS ANNEX E TO THIS JOINT PROXY STATEMENT/PROSPECTUS AND IS
INCORPORATED HEREIN BY REFERENCE. STOCKHOLDERS OF STAR ARE URGED TO READ
DEUTSCHE BANK'S OPINION IN ITS ENTIRETY. THE SUMMARY OF DEUTSCHE BANK'S OPINION
SET FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY
BY REFERENCE TO THE FULL TEXT OF DEUTSCHE BANK'S OPINION.

     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;

                                       68
<PAGE>   82

     - 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 or the letter of intent for the
sale of PT-1 Communications was signed. Deutsche Bank did not consider the
WORLDxCHANGE merger or the terms of the proposed sale of PT-1 when analyzing the
fairness, from a financial point of view, of the 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 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.

                                       69
<PAGE>   83

     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 and the results derived from these 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, collectively, the "selected
comparable 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.

     Such financial information and valuation measurements included, among other
things:

     - total enterprise value, or TEV;

     - ratios of TEV to sales for the third quarter of 1999 annualized, or LQA;

     - ratios of TEV to estimated sales for the year 2000;

     - ratios of TEV to EBITDA for the LQA;

     - ratios of TEV to property, plant and equipment, or PP&E, net of
       depreciation; and

     - ratios of TEV to gross PP&E.

     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.

                                       70
<PAGE>   84

     For each of the selected comparable companies, Deutsche Bank calculated
five trading multiples: TEV to sales of the LQA and for 2000 estimated; TEV to
EBITDA of LQA; and TEV to PP&E net of depreciation and to gross PP&E. 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 GPP&E multiple were based solely on the
    GPP&E multiple of Global Telesystems because the GPP&E 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 TEV 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 TEV,
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:

The gross PP&E 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 TEV as a multiple of the gross PP&E.

     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 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) by former STAR stockholders and by the
stockholders of World Access before the STAR merger of 20.6%

                                       72
<PAGE>   86

and 79.4%, respectively, and approximately 28.9% and 71.1%, respectively, of the
combined company's TEV (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).

     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 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 TEVs,
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 TEVs, 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:

     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:

     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
date and four weeks prior to announcement date. The premium to STAR's share
price was calculated

                                       73

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 indicated:

     Other considerations and analyses.  In connection with its opinion Deutsche
Bank also considered, among other things, (i) 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, (ii) historical
exchange ratios of World Access and STAR based on historical trading prices,
(iii) STAR cumulative price histogram, and (iv) 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 and factors 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 and factors considered
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 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

                                       74
<PAGE>   88

board of directors. As described above, the opinion and presentation of Deutsche
Bank to the STAR board of directors were only two 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 TO BE RECEIVED 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 outstanding share of STAR
       common stock will be converted into the right to receive the number of
       shares of World Access common stock obtained by solving for "X" in the
       following equation:

                                  X = 7.81 + Z
                                      --------
                                         20

        "Z" equals the net cash proceeds in excess of $150.0 million received by
        STAR upon completion of the sale of its subsidiary, PT-1 (i.e., cash
        proceeds net of all taxes, fees, expenses and costs incurred in
        connection with such sale), divided by 62,856,702 (initially calculated
        to be the number of issued and outstanding shares of STAR common stock,
        plus the number of shares underlying outstanding STAR stock options and
        warrants as of February 11, 2000). World Access and STAR can give you no
        assurance that PT-1 can be sold or that it can be sold for net cash
        proceeds in excess of $150.0 million; therefore, we can give you no
        assurance that "Z" will be greater than zero. The number of shares of
        World Access common stock to be issued for each share of STAR common
        stock is referred to as the exchange ratio.

        The sale of PT-1 is a condition to World Access' obligation to complete
        the STAR merger. If, however, such sale is not completed by the date on
        which the STAR merger is to be completed

                                       75
<PAGE>   89

        and World Access decides to proceed with the STAR merger, the exchange
        ratio will be modified by deleting "Z." Further, in such event, a holder
        of STAR common stock and STAR stock options or warrants will have the
        right to receive an additional number of shares of World Access common
        stock upon completion of such sale or exercise of such options or
        warrants equal to the net cash proceeds from the PT-1 sale in excess of
        $150.0 million divided by 20. You should note that the decision to waive
        the sale of PT-1 as a closing condition is a matter within World Access'
        sole and exclusive discretion, and World Access is under no obligation
        to waive such condition.

     - Under the second form of merger consideration, each share of STAR common
       stock would be converted into the right to receive the number of shares
       of World Access common stock equal to 60% of the exchange ratio and an
       amount in cash equal to 40% of the sum of $7.81 plus "Z."

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, in lieu 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 acquire 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. The exercise price will be the exercise price specified in the
STAR stock option or warrant multiplied by the exchange ratio. 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.

CLOSING; EFFECTIVE TIME OF THE STAR MERGER

     The closing of the STAR merger will occur on the second business day
following the satisfaction or waiver of all conditions to the completion of the
STAR merger, or at such other time as World Access and STAR agree. On the date
of the closing of the STAR merger, World Access and STAR will file a certificate
of merger with the Secretary of State of the State of Delaware, at which time
the STAR merger will be effective, unless World Access and STAR agree to and
specify a subsequent effective time in the certificate of merger.

CERTAIN MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE STAR MERGER

     The following is a summary of certain material federal income tax
consequences of the STAR 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, as disclosed herein, to the extent the
following discussion summarizes matters of law or legal conclusions, it is
accurate in all material respects under the federal income tax laws as now in
effect. The following discussion is general in nature and does not purport to be
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: (i) an insurance company; (ii) a tax-exempt organization;
(iii) an employee stock ownership plan; (iv) a bank; (v) a broker, dealer or
financial institution; (vi) 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; (vii) a holder that has a "functional currency"
other than the United States dollar; (viii) a holder subject to the alternative
minimum tax; (ix) 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; (x) a holder who acquired shares of STAR
common stock

                                       76
<PAGE>   90

pursuant to the exercise of options or otherwise as compensation or through a
tax-qualified retirement plan; or (xi) 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 (for example, 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 summary assumes that as
a STAR stockholder, you hold your STAR common stock as a "capital asset"
(generally, property held for investment) within the meaning of Section 1221 of
the Internal Revenue Code of 1986, as amended, or the Code. This summary is
based on the Code and final, temporary and proposed treasury regulations
promulgated thereunder, 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 continuity and validity of this summary.

     We have not requested a ruling from the IRS with respect to the federal
income tax consequences of the STAR merger nor is consummation 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 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 accuracy of 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 tax discussion set forth below.

     The opinion represents such counsel's best judgment as to the tax treatment
of the STAR merger, but neither binds the IRS nor precludes it from adopting a
contrary position, and no assurance can be given that contrary positions will
not be successfully asserted by the IRS 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 STAR merger will constitute a "reorganization" within the
meaning of Section 368(a) of the Code, and that STAR completes the sale of PT-1
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.  Under Section 354 of the
Code, 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 time under Delaware corporate law when the STAR merger becomes effective.

                                       77
<PAGE>   91

     Receipt of World Access stock and cash.  If World Access exercises its
right to pay you cash as part of the STAR merger consideration, the amount of
cash World Access can elect to pay has been limited so that the aggregate amount
of such cash payments will not result in the STAR merger failing to constitute a
"reorganization" within the meaning of Section 368(a) of the Code. 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
for federal income tax purposes (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, such loss cannot be recognized by you.

     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 as a result of the receipt of cash 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 Section 356 of the
Code, in which case the gain will be characterized as ordinary income to the
extent of your ratable share of the accumulated and undistributed earnings and
profits of STAR.

     To determine whether any such recognized gain is capital gain or ordinary
income, 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 amount 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, under the redemption tests of Section 302 of the Code, and for
this purpose, taking into consideration the stock ownership attribution rules of
Section 318 of the Code not only World Access stock directly owned by you, but
also World Access stock owned by certain of your family members and other
entities in which you have an interest, and any World Access stock you have a
right or option to acquire, 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 interest in World
Access. If either of these redemption tests under Section 302(b) of the Code is
satisfied, then "exchange" treatment occurs under Section 302(a) of the Code,
and such 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. The Section 302 redemption tests and the application of the
stock ownership attribution rules are complex and the tax consequences to you
will depend upon your particular facts and circumstances as a STAR stockholder.
You are urged to consult with your tax advisor with respect to these matters.

     If none of the redemption tests under Section 302 of the Code is satisfied,
when you exchange shares of STAR common stock for a combination of cash and
shares of World Access common stock, you will be treated as having received a
dividend distribution in that exchange under Section 301 of the Code. 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

                                       78
<PAGE>   92

and profits (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" under Section 243 of the
Code; such dividend distribution may, however, also be subject to the
"extraordinary dividend" provisions of Section 1059 of the Code.

     Cash for fractional shares.  Irrespective of whether World Access elects to
pay cash to STAR stockholders as part of the STAR merger consideration, it will
pay cash in lieu of fractional shares. Based on the current published ruling
position of the IRS, the cash you receive in lieu of a fractional share interest
in World Access common stock will be treated as received in "exchange" for such
fractional share interest under Section 302(a) of the Code. 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, subject to the provisions and
limitations of Section 302 of the Code. If, as a result of such redemption, you
own no World Access stock either directly or through the application of the
stock ownership attribution rules of Section 318 of the Code, then "exchange"
treatment occurs under Section 302(a) of the Code. If exchange treatment
applies, 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
IRS 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.

  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. Under
Section 162(m) of the Code, World Access may not be allowed to deduct
compensation payable to a STAR employee in connection with the STAR merger to
the extent that the aggregate compensation exceeds $1.0 million under certain
circumstances. No determination can be made at this time whether Section 162(m)
will apply, and therefore, Long Aldridge & Norman LLP has expressed no opinion
with respect to this matter.

     The PT-1 sale.  Among other statutory and judicial requirements, in order
for the STAR merger to qualify as a "reorganization," STI Merger Co. must
acquire "substantially all" of STAR's assets within the meaning of Section
368(a)(2)(D) of the Code. For private letter ruling purposes, the IRS has
indicated that the transfer of seventy percent (70%) of the fair market value of
the target corporation's gross assets and ninety percent (90%) of the fair
market value of the target corporation's net assets will be deemed
"substantially all." Judicial decisions have been substantially more lenient,
and in addition to the percentage of property transferred, have focused on the
nature of the assets retained by the target corporation and the purpose for
their retention in making this determination. Under the STAR merger agreement,
STAR's completion of the PT-1 sale is a closing condition to World Access'
obligation to consummate the STAR merger.

                                       79
<PAGE>   93

     The IRS has also issued a published ruling holding that a pre-merger sale
of fifty percent (50%) of its historic business assets by the acquired
corporation for cash did not violate the "substantially all" requirement because
all the remaining assets (including the cash proceeds) were transferred to the
acquiring corporation. Based on STAR's representations that the IRS private
letter ruling requirements regarding the "substantially all" requirement will be
met, the IRS published ruling position on pre-merger asset sales by an acquired
corporation and other IRS and judicial authority, the "substantially all"
requirement should be met in the STAR merger.

     In this regard, World Access must also satisfy the "continuity of business
enterprise" requirement set forth in Section 1.368-1(d) of the treasury
regulations in order for the STAR merger to qualify as a "reorganization" under
Section 368(a) of the Code. This test is satisfied if STI Merger Co. continues
STAR's "historic business" or uses a significant portion of STAR's historic
assets in a business. World Access has represented to counsel that STI Merger
Co. will satisfy this test, notwithstanding the PT-1 sale. Based on such World
Access representations and the other available IRS and judicial authority, the
"continuity of business enterprise" requirement should also be met with respect
to the STAR merger.

     Limitation on STAR tax attributes.  Under Section 381 of the Code, STI
Merger Co. will succeed to the net operating losses ("NOLs"), 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 Sections 381, 382, 383, 384 of the 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" (the "SRLY")
rules. Under Section 382 of the Code, special limitations apply following an
"ownership change" to the use of NOLs and "net unrealized built-in losses" in
excess of a threshold amount recognized during the five-year period following an
ownership change. 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 NOLs 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 IRS (5.84%
for May 2000). The Section 382 limitation for any post-ownership change year
will generally be zero unless the loss corporation satisfies the "continuity of
business enterprise" requirement (described in the immediately prior paragraph)
for the two-year period following the ownership change.

     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
consummation of the STAR merger. The World Access consolidated group's ability
to utilize the STAR loss subgroup's NOL carryover as of December 31, 1999, and
any additional NOL carryover of such loss subgroup arising in STAR's taxable
year beginning January 1, 2000 during the period prior to the effective time of
the STAR merger, after taking into account the PT-1 sale (collectively, the
"pre-change STAR loss subgroup NOLs") against future World Access consolidated
federal taxable income will be subject to an annual loss subgroup Section 382
limitation. Successive ownership changes with respect to the STAR loss subgroup
or members thereof may result in an additional, lesser (but never in a greater)
Section 382 limitation with respect to previously limited NOLs.

     An additional limitation may apply under which the pre-change STAR loss
subgroup tax NOLs can only be used to the extent of the "qualifying SRLY
subgroup" members' aggregate, cumulative contribution to World Access
consolidated taxable income (the "SRLY limitation"). Because the STAR loss
subgroup and its SRLY NOL subgroup should be treated as co-extensive, and the
Section 382 ownership change and SRLY event will occur at the same time, the
SRLY limitation should be eliminated with respect to the STAR loss subgroup
NOLs. However, the STAR subgroup for built-in losses may not be co-extensive
with the STAR loss subgroup and its SRLY NOL subgroup and, if not, then if such
STAR subgroup built-in losses exceed a specified threshold amount, such built-in
losses recognized during the five-year period following the SRLY event may still
be subject to limitation under

                                       80
<PAGE>   94

the SRLY rules. Notwithstanding the foregoing, it is anticipated that any NOL
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 NOL, and has a
consolidated NOL carryover. As such, it constitutes a "loss group." Although it
is currently unclear whether the World Access loss group will undergo a Section
382 ownership change as a result of consummating either or both the STAR merger
and the WORLDxCHANGE merger, 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 NOL carryover as of December 31, 1999,
and certain "recognized built-in losses" against its future consolidated federal
taxable income years 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 NOLs will be subject to the lowest amount of Section 382 limitation
which results from any of such successive ownership changes. If instead,
consummation 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
to former STAR stockholders a letter of transmittal and instructions for use in
surrendering STAR stock certificates in exchange for the applicable STAR merger
consideration. When STAR stockholders deliver their STAR stock certificates to
the exchange agent along with an executed letter of transmittal and any other
required documents, their STAR stock certificates will be canceled and they will
receive the number of full shares of World Access common stock to which they are
entitled under the STAR merger agreement and a check in an amount equal to the
cash consideration to which such stockholder is entitled, if any. STAR
stockholders also will receive payment of cash in lieu of any fractional shares
of World Access common stock which would have been otherwise issuable to them in
the STAR merger. If World Access elects to pay cash as part of the merger
consideration, STAR stockholders will also receive the amount of cash to which
they are entitled under the STAR merger agreement upon delivery to the exchange
agent of their STAR stock certificates, an executed letter of transmittal and
any other required documents.

     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.

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

     The shares of World Access common stock to 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 of World Access common
stock issued to any person who is an affiliate of either World Access or STAR.
Persons who may be deemed to be 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 and directors, as well
as their respective principal stockholders. Affiliates may not sell their shares
of World Access common stock acquired in the STAR merger except pursuant to (i)
an effective registration statement under the Securities Act of 1933 covering
the resale of those shares, (ii) Rule 145 under the Securities Act of 1933 or
(iii) any other applicable exemption under the Securities Act of 1933.

ACCOUNTING TREATMENT OF THE STAR MERGER

     We intend 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, or the HSR, 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, STAR 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 March 16, 2000. No
further action under the HSR 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. Accordingly, at any time before or after
the completion of the STAR merger, either the Antitrust Division of the
Department of Justice or the Federal Trade Commission could take action under
the antitrust laws. 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, 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 STAR merger under the
antitrust laws will not be made or that, if a challenge is made, it would not be
successful.

     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 notification is considered by
the German Cartel Office to be complete. During the initial one month waiting
period, the German Cartel Office may decide to open a further investigation of
the STAR merger. If a further investigation is instituted, the STAR merger may
not be completed until a further three month period has expired or the STAR
merger has been cleared. At any time during the period, the German Cartel Office
may act to block the STAR merger or impose conditions upon its completion. There
can be no assurance that a challenge to the STAR merger on competition law
grounds will not be made or that, if such a challenge is made, it would not be
successful in Germany. 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 FCC
require prior notice or approval of the STAR merger. Applications or notices, as
required, requesting either approval or providing notification of the STAR
merger have been filed on behalf of World Access and STAR in 48 states and with
the FCC. The governing 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 FCC has approved the STAR merger.

                                       82
<PAGE>   96

     Other than approvals by state and federal authorities having jurisdiction
over telecommunications activities conducted by World Access or STAR, we are not
aware of any other material governmental or regulatory approval required for
completion of the STAR 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.

RIGHTS OF DISSENTING STAR STOCKHOLDERS

     If, pursuant to the terms of the STAR merger agreement, 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, any holder of STAR common stock
who does not wish to accept this consideration has the right to demand the
appraisal of and to be paid, in cash, the fair value of the shares of STAR
common stock under Section 262 of the General Corporation Law of the State of
Delaware. The fair value of the STAR common stock will exclude any element of
value arising from the completion or expectation of the STAR merger. The
following discussion represents only a summary of the material provisions of
Section 262 and is qualified in its entirety by reference to the full text of
Section 262, which is reprinted in its entirety as Annex G to this joint proxy
statement/prospectus. A person having a beneficial interest in STAR common stock
as of the STAR record date held of record in the name of another person, such as
a nominee, and who wishes to exercise his or her right to appraisal to the
extent such right exist, must act promptly to cause the record holder to follow
the steps summarized below and set forth in Annex G properly and in a timely
manner to perfect any appraisal rights provided under Section 262.

     THIS JOINT PROXY STATEMENT/PROSPECTUS SHALL CONSTITUTE THE NOTICE REQUIRED
BY SECTION 262. ANY HOLDER OF STAR COMMON STOCK WHO WISHES TO EXERCISE APPRAISAL
RIGHTS SHOULD REVIEW THE FOLLOWING DISCUSSION AND ANNEX G CAREFULLY BECAUSE
FAILURE TO TIMELY AND PROPERLY COMPLY WITH THE PROCEDURES SPECIFIED WILL RESULT
IN THE LOSS OF APPRAISAL RIGHTS UNDER SECTION 262 OF THE GENERAL CORPORATION LAW
OF THE STATE OF DELAWARE AND WILL RESULT IN SUCH STOCKHOLDER RECEIVING THE
CONSIDERATION PROVIDED FOR IN THE STAR MERGER AGREEMENT.

     Under Section 262, a record holder of STAR common stock who will receive a
combination of World Access common stock and cash (other than cash paid in lieu
of fractional share) pursuant to the terms of the STAR merger agreement, who
makes the demand described below with respect to such shares, who continuously
is the record holder of such shares from the time of making a written demand for
appraisal through the effective time of the STAR merger, who otherwise complies
with the statutory requirements set forth in Section 262, and who neither votes
in favor of approval of the STAR merger nor consents thereto in writing will be
entitled to have his or her STAR stock appraised by the Court of Chancery of the
State of Delaware and to receive payment of the "fair value" of such shares as
described below. STAR stockholders considering seeking appraisal should
recognize that the fair value of shares could be determined to be more, the same
or less than the value of the consideration provided for in the STAR merger
agreement.

     A record holder of STAR common stock wishing to exercise appraisal rights
must deliver to STAR at the address below, before the taking of the
stockholders' vote on the STAR merger, a written demand for appraisal of his or
her STAR common stock. A proxy or vote against the STAR merger agreement will
not constitute a demand for appraisal. A written demand is essential. Such
written demand must inform STAR of the stockholder's identity and that such
stockholder intends thereby to demand appraisal of the stockholder's shares. All
written demands for appraisal of STAR common stock should be sent or delivered
to STAR at 223 East De La Guerra Street, Santa Barbara, California 93101,
Attention: Corporate Secretary. In addition, a record holder of STAR common
stock wishing to exercise his or her appraisal rights must hold such shares of
record on the record date, on the date the written demand for appraisal rights
is made and must hold such shares continuously through the effective time of the
STAR merger. Stockholders who hold their STAR common stock in nominee form and
who wish to exercise appraisal rights must take all necessary steps in order
that a demand for appraisal is made by the record holder of such shares and are
urged to consult with their nominee to determine the appropriate procedures for
the making of a demand for appraisal by the record holder.

                                       83
<PAGE>   97

     Within ten days after the effective time of the STAR merger, World Access
must send a notice as to the effectiveness of the STAR merger to each person who
has satisfied the appropriate provisions of Section 262. Within 120 days after
the effective time of the STAR merger, any former holder of STAR stock who has
complied with the requirements for exercise of appraisal rights under Section
262 will be entitled, upon written request, to receive from World Access a
statement setting forth (i) the aggregate number of shares of STAR stock not
voted in favor of the STAR merger agreement and with respect to which demands
for appraisal have been received and (ii) the aggregate number of holders of
such shares. Any such statement must be mailed within ten days after a written
request therefor has been received by World Access or within ten days after
expiration of the period for delivery of demand for appraisal, whichever is
later.

     Within 120 days after the effective time of the STAR merger, World Access
or any record holder of STAR stock who has complied with the requirements of
Section 262 may file a petition in the Court of Chancery of the State of
Delaware demanding a determination of the "fair value" of such shares. World
Access is not under any obligation to file this petition and does not currently
intend to file such petition. Accordingly, it is the obligation of the holders
of STAR common stock to initiate all necessary action to perfect their appraisal
rights within the time prescribed in Section 262. A record holder of STAR common
stock will fail to perfect, or effectively lose, his or her right to appraisal
if no petition for appraisal of share of STAR common stock is filed within 120
days after the effective time of the STAR merger.

     If a petition for an appraisal is timely filed, at a hearing on such
petition, the Court of Chancery of the State of Delaware will determine the
holders of STAR common stock entitled to appraisal rights and thereafter will
appraise the "fair value" of the STAR stock, exclusive of any element of value
arising from the completion or expectation of the STAR merger. The Court of
Chancery may require the stockholders who have demanded an appraisal for their
shares and who had stock represented by certificates to submit their stock
certificates to the Register in Chancery for notation thereon of the pendency of
the appraisal proceedings. If any stockholder fails to comply with such
direction, the Court of Chancery may dismiss the proceedings as to such
stockholder.

     In determining fair value, the Court of Chancery is to take into account
all relevant factors. In Weinberger v. UOP Inc., the Delaware Supreme Court
discussed the factors that could be considered in determining fair value in an
appraisal proceeding, stating that "proof of value by any techniques or methods
which are generally considered acceptable in the financial community and
otherwise admissible in court" should be considered, and that "fair price
obviously requires consideration of all relevant factors involving the value of
a company." The Delaware Supreme Court stated that in making this determination
of fair value the court must consider market value, asset value, dividends,
earning prospects, the nature of the enterprise and any other factors which
could be ascertained as of the date of the merger which throw light on future
prospects of the merged corporation. In Weinberger, the Delaware Supreme Court
stated that "elements of future value, including the nature of the enterprise,
which are known or susceptible of proof as of the date of the Merger and not the
product of speculation, may be considered." Section 262, however, provides that
fair value is to be "exclusive of any element of value arising from the
accomplishment or expectation of the Merger."

     The Court of Chancery will also determine the amount of interest, if any,
to be paid upon the amounts to be received by persons whose STAR common stock
has been appraised. The costs of the action may be determined by such court and
imposed upon the parties as the court deems equitable in the circumstances. Upon
application of a stockholder, the Court of Chancery may also order that all or a
portion of the expenses incurred by any holder of STAR common stock in
connection with an appraisal, including without limitation, reasonable
attorneys' fees and the fees and expenses of experts utilized in the appraisal
proceeding, be charged pro rata against the value of all of the STAR common
stock entitled to appraisal.

     If any record holder of STAR common stock who demands appraisal of his or
her shares under Section 262 fails to perfect, or effectively withdraws or loses
his or her right to appraisal, as provided in the General Corporation Law of the
State of Delaware, the STAR common stock of such stockholder will

                                       84
<PAGE>   98

be entitled to receive the consideration provided for in the STAR merger
agreement. A holder may withdraw his or her demand for appraisal by delivering
to World Access a written withdrawal of his or her demand for appraisal and
acceptance of the consideration provided for in the STAR merger agreement,
except that any such attempt to withdraw made more than 60 days after the
effective time of the STAR merger will require the written approval of World
Access. Notwithstanding the foregoing, no appraisal proceeding filed in the
Court of Chancery shall be dismissed as to any stockholder without the approval
of the court. Failure to follow the steps required by Section 262 for perfecting
appraisal rights may result in the loss of such rights.

     Any record holder of STAR common stock who has duly demanded an appraisal
in compliance with Section 262 will not, after the effective time of the STAR
merger, be entitled to vote the STAR common stock subject to such demand for any
purpose or be entitled to the payment of dividends or other distributions on
those shares, except dividends or other distributions payable to record holders
of shares of STAR common stock as of a date prior to the effective time of the
STAR merger.

INTERESTS OF CERTAIN PERSONS IN THE STAR MERGER

  Option plans and change in control arrangements

     In connection with the recommendation of STAR's board of directors, STAR's
stockholders should be aware that certain executive officers and directors have
certain 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, upon the grant of stock
options, stock appreciation rights, or SARs, stock units or restricted shares,
the administrator of the plan, which is a committee of the board of directors,
may provide for the acceleration of the stock options, SARs, stock units or
restricted shares granted to employees and outside directors in the event of a
change in control. Under the plan and the 1996 Outside Director Nonstatutory
Stock Option Plan, the definition of a change in control includes a merger or
consolidation of STAR, certain changes in the composition of the board of
directors or the acquisition of 50% or more of the combined voting power of
STAR's outstanding stock. The STAR merger constitutes a change in control under
the plan.

     Pursuant to STAR's 1996 Outside Director Nonstatutory Stock Option Plan, if
a change in control has occurred or if the board of directors has in good faith
determined that a change in control is about to occur, the board of directors
may decide that it is necessary or desirable to accelerate the exercisability of
outstanding options granted under the plan and provide an exercise period during
which the accelerated options may be exercised. The board of directors also has
the discretion to terminate any outstanding options that have been accelerated
but not exercised during the exercise period. In the event of a merger of STAR
into another corporation in which holders of common stock receive cash for their
shares, the board of directors may provide that all outstanding options granted
under the plan shall automatically convert into the right to receive cash equal
to the difference between the exercise price and the amount paid to holders of
common stock pursuant to the merger. The STAR merger constitutes a change in
control under the 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, upon a change in control, all currently outstanding and future options
held by Kelly Enos that have not vested will become exercisable on a date that
is five business days prior to the consummation of the change in control. The
STAR merger constitutes a change in control. As of             , 2000, Ms. Enos
held options to purchase                shares that were not exercisable. These
options will accelerate upon the STAR merger.

     On January 3, 2000 STAR's non-executive stock option committee determined
that, upon a change in control, all currently outstanding and future options
held by David Vaun Crumly that have not vested will

                                       85
<PAGE>   99

become exercisable on a date that is five business days prior to the
consummation of the change in control. The STAR merger constitutes a change in
control. As of             , 2000, Mr. Crumly held options to purchase
               shares that were not exercisable. These options will accelerate
upon the STAR merger.

  Change in control agreement

     In January 1996, STAR entered into an employment agreement with David Vaun
Crumly, whereby Mr. Crumly became Executive Vice President.

     The agreement provides that in the event of a sale transaction, in lieu of
commissions on STAR's accounts, 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 the
sale transaction. The percentage is either ten, twenty or thirty percent,
depending on the size of the monthly gross sales. A sale transaction is the
acquisition of more than 75% of the voting securities of STAR pursuant to a
tender offer or exchange approved in advance by the board of directors. 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 may 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.

  Registration rights under voting agreement of Christopher Edgecomb

     World Access and Christopher Edgecomb entered into a voting and stock
transfer restriction agreement pursuant to which World Access granted to Mr.
Edgecomb unlimited "piggyback" registration rights. Subject to certain
exceptions and qualifications, these registration rights entitle Mr. Edgecomb 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 bear all expenses of Mr.
Edgecomb 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.

                           THE STAR MERGER AGREEMENT

     This section of the joint proxy statement/prospectus describes the STAR
merger agreement. While we believe that the description covers the material
terms of the STAR merger agreement, this summary 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, and we urge you to read it
carefully.

THE STAR MERGER/EFFECTIVE TIME

     The STAR merger agreement provides that upon completion of the STAR merger,
STAR will be merged with and into STI Merger Co., which is a wholly-owned
subsidiary of World Access. STI Merger Co. will survive the merger. On the
closing date of the STAR merger, World Access and STAR will file a certificate
of merger with the Secretary of State of the State of Delaware. At the time of
the filing of the certificate of merger, the STAR merger will be effective
unless World Access and STAR agree to and specify a subsequent effective time in
the certificate of merger.

                                       86
<PAGE>   100

THE STAR MERGER CONSIDERATION

     Upon completion of the STAR merger, each outstanding share of STAR common
stock held by STAR or a subsidiary of STAR will no longer be outstanding and
will be canceled and retired, and no consideration will be delivered for such
shares.

     Upon completion of the STAR merger, each outstanding share of STAR common
stock not held by STAR or a subsidiary of STAR will be automatically canceled
and converted into the right to receive, at the election of World Access, one of
the following forms of consideration:

     - the number of shares of World Access common stock obtained by solving for
       "X" in the following formula which is the exchange ratio:

                                  X = 7.81 + Z
                                      --------
                                         20

        "Z" equals (i) the net cash proceeds in excess of $150.0 million
        received by STAR upon the completion of the sale of its subsidiary,
        PT-1, net of all taxes, fees, expenses and costs incurred in connection
        with such sale, divided by (ii) 62,856,702 (initially calculated to be
        the number of issued and outstanding shares of STAR common stock, plus
        the number of shares underlying outstanding STAR stock options and
        warrants as of February 11, 2000). World Access and STAR can give you no
        assurance that PT-1 can be sold or that it can be sold for net cash
        proceeds in excess of $150.0 million; therefore, we can give you no
        assurance that "Z" will be greater than zero.

        The sale of PT-1 is a condition to World Access' obligation to complete
        the STAR merger. If, however, such sale is not completed by the date on
        which the STAR merger is to be completed and World Access decides to
        proceed with the STAR merger, the exchange ratio will be modified by
        deleting "Z." Further, in such event, a holder of STAR common stock and
        STAR stock options or warrants will have the right to receive an
        additional number of shares of World Access common stock upon completion
        of such sale or exercise of such options or warrants equal to the net
        cash proceeds from the PT-1 sale in excess of $150.0 million divided by
        20. You should note that the decision to waive the sale of PT-1 as a
        closing condition is a matter within World Access' sole and exclusive
        discretion, and World Access is under no obligation to waive such
        condition.

     - the number of shares of World Access common stock equal to 60% of the
       exchange ratio and an amount in cash equal to 40% of the sum of $7.81
       plus "Z," as defined above.

No fractional shares will be issued. Instead, STAR stockholders will receive
cash based on the market price of World Access common stock. In addition, shares
of STAR common stock for which dissenters' rights of appraisal have been
perfected pursuant to the General Corporation Law of the State of Delaware will
not be entitled to receive the merger consideration described above.

respective businesses in the ordinary course in all material respects and will
use reasonable efforts to preserve intact their lines of business, maintain
their rights and franchises and preserve their relationships with customers and

respective businesses in compliance with specific restrictions relating to the
following:

     - the issuance and redemption of securities;

     - capital expenditures or other investments;

     - the incurrence of indebtedness;

     - the settlement of litigation;

     - the entering into of contracts;

     - accounting policies and procedures; and

     - actions which would jeopardize the tax treatment of the STAR merger.

NO OTHER NEGOTIATIONS INVOLVING STAR

     Until the STAR merger is completed or the STAR merger agreement is
terminated, STAR has agreed that neither it nor its subsidiaries will, and that
it will cause its employees, officers, directors, affiliates, agents, and
representatives not to, directly or indirectly take any of the following actions
without the prior written consent of World Access:

     - solicit, initiate, encourage or knowingly facilitate (including by way of
       furnishing information or engaging in discussions or negotiations) any
       inquiries regarding or the making of an acquisition proposal, as defined
       below;

     - participate in any discussions or negotiations regarding an acquisition
       proposal;

     - disclose any confidential information to any person in connection with an
       acquisition proposal; or

     - knowingly facilitate any effort or attempt to make, implement or accept
       an acquisition proposal.

                                       88
<PAGE>   102

     Notwithstanding the limitations on STAR's actions, STAR may, in response to
an unsolicited, bona fide written acquisition proposal, (i) recommend approval
by its stockholders of such proposal or withdraw, modify or qualify in a manner
adverse to World Access its recommendation that the STAR stockholders approve
the STAR merger or (ii) furnish information and engage in discussions regarding
such proposal, provided that:

     - the STAR stockholders meeting has not occurred;

     - with respect to recommending approval of such acquisition proposal or
       changing the recommendation to the STAR stockholders regarding the
       approval of the STAR merger, the STAR board of directors concludes that
       such acquisition proposal is a superior proposal, as defined below, and
       terminates the STAR merger agreement and pays the termination fee
       described below;

     - with respect to furnishing information or engaging in discussions
       regarding such acquisition proposal, the STAR board of directors
       concludes that such proposal could reasonably be expected to result in a
       superior proposal;

     - prior to providing information to the third party making an acquisition
       proposal, STAR enters into a confidentiality agreement with such third
       party having terms at least as stringent as those contained in the
       confidentiality agreement between World Access and STAR; and

     - prior to providing information or entering into discussions with such
       third party, STAR notifies World Access of such third party inquiries,
       proposals or offers, including the identity of the third party and the
       material terms of the inquiries, proposals or offers.

     STAR has agreed that it will keep World Access informed of the state of
acquisition proposals. STAR also agreed that it and its subsidiaries would, and
would cause their officers, directors, affiliates, employees, agents and
representatives to, discontinue any discussions or negotiations regarding an
acquisition proposal in effect on February 11, 2000.

     An "acquisition proposal" is any proposal or offer regarding:

     - a business combination or similar action involving STAR;

     - any purchase or sale of a material portion of the assets 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.

     A "superior proposal" is a written proposal by a person unaffiliated with
STAR which is for:

     - a business combination or similar action involving STAR as a result of
       which STAR's stockholders prior to such action no longer own 50% of the
       voting securities of the surviving entity or the individuals serving on
       the board of directors of STAR prior to such action do not constitute a
       majority of the board of directors of the surviving entity;

     - a sale, lease, exchange, transfer or other disposition (in one or a
       series of transactions) of at least 50% of the assets of STAR and its
       subsidiaries, taken as a whole; or

     - the acquisition of at least 50% of the common stock of STAR through a
       business combination, exchange offer or otherwise.

In addition, to be a "superior proposal," such proposal must be on terms which
the STAR board of directors concludes (after consultation with its financial
advisors and outside legal counsel), taking into account all legal, financial,
regulatory and other aspects of the proposal, would result in a more favorable
transaction, from a financial point of view, to the STAR stockholders than the
STAR merger and is reasonably capable of being concluded.

<PAGE>   103

TREATMENT OF STAR STOCK OPTIONS AND WARRANTS

     Upon completion of the STAR merger, each outstanding option or warrant to
purchase STAR common stock 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. 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.

     World Access will file all required registration statements (on Form S-8 or
another appropriate form) with respect to each STAR stock option or warrant
converted into a World Access stock option, as well as the shares of World
Access common stock underlying such option. World Access will keep such
registration statements current for so long as such options remaining
outstanding.

MANAGEMENT SERVICES

     To the extent permitted by applicable law, World Access and STAR intend to
enter into a management agreement under which World Access would provide
management services to STAR pending the completion of the STAR merger.

BOARD OF DIRECTORS OF WORLD ACCESS

     World Access and STAR have agreed that immediately following the completion
of the STAR merger, World Access will cause one STAR designee to be elected to
the World Access board of directors. The STAR designee will be Christopher E.
Edgecomb, or such other person designated by STAR and agreed to by World Access
prior to the completion of the STAR merger.

INTERIM FINANCING OF STAR

     World Access and STAR have agreed that World Access will make available up
to $25.0 million in secured financing to STAR and up to $10.0 million in secured
financing to STAR's subsidiary, STAR Telecommunications GmbH. This financing
will mature at the earlier of one year from February 11, 2000 and 90 days after
the termination of the STAR merger agreement. In the event of a breach or
default by STAR under the STAR merger agreement, all such financing will become
immediately due and payable.

CONDITIONS TO COMPLETION OF THE STAR MERGER

     The respective obligations of World Access and STAR to complete the STAR
merger are subject to the satisfaction or waiver of each of the following
conditions before completion of the STAR merger:

     - the waiting period (and any extension thereof) applicable to the STAR
       merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
       amended, must be terminated or must expire;

     - the STAR merger agreement and the STAR merger must be approved by the
       requisite vote of the stockholders of World Access and STAR; and

     - the registration statement with respect to the shares of World Access
       common stock to be issued in the STAR merger must be declared effective
       by the Securities and Exchange Commission, and the registration statement
       must not be subject to a stop order or a threatened proceeding with
       respect to a stop order.

     World Access' obligations to complete the STAR merger are subject to the
satisfaction or waiver of each of the following additional conditions before
completion of the STAR merger:

     - STAR's representations and warranties must be true and correct as of
       February 11, 2000 and as of the date of the completion of the STAR
       merger, except to the extent the representations and

                                       90
<PAGE>   104

       warranties speak only as of a particular date and except where any
       failure to be true and correct would not have a material adverse effect
       (as defined below) on World Access or the surviving corporation;

     - STAR must perform or comply in all material respects with all of its
       material agreements and covenants required by the STAR merger agreement
       to be performed or complied with at or before completion of the STAR
       merger;

     - all consents and approvals required of STAR to complete the STAR merger,
       the failure of which to obtain would have a material adverse effect on
       World Access or the surviving corporation, must be obtained. However, if
       the failure of World Access to use reasonable efforts to obtain such
       consents and approvals is the cause of the failure to obtain such
       consents and approvals, World Access must complete the STAR merger
       (assuming all other conditions to World Access' obligations are fulfilled
       or waived);

     - no material adverse effect with respect to STAR, taken as a whole with
       its subsidiaries, shall have occurred since February 11, 2000, 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 relating specifically to STAR, or (iii) to the
       trading price of STAR common stock;

     - World Access must receive from STAR's legal counsel a legal opinion
       reasonably satisfactory to World Access with respect to certain matters;

     - no laws may be adopted or injunctions or orders issued by a court or
       other governmental entity having the effect of making the STAR merger
       illegal or prohibiting the completion of the STAR merger or which would
       otherwise have a material adverse effect on World Access or the surviving
       corporation. However, World Access must complete the STAR merger
       (assuming all other conditions to its obligations are fulfilled or
       waived) if its failure to use reasonable efforts to complete the STAR
       merger was the cause of, or resulted in, any such order or injunction;

     - STAR must comply with all procedures and requirements applicable to it
       under the dissenters' rights section of the General Corporation Law of
       the State of Delaware, the period for exercising dissenters' rights of
       appraisal in connection with the STAR merger must expire, and fewer than
       1% of the shares of STAR common stock must have exercised dissenters'
       rights of appraisal;

     - STAR must complete the sale of PT-1 for net cash proceeds of at least
       $150.0 million pursuant to an agreement reasonably satisfactory to World
       Access. However, if such sale has not been completed prior to the closing
       date of the STAR merger (but STAR has entered into a definitive agreement
       satisfactory to World Access with respect to such sale) and World Access
       decides in its sole discretion to waive the sale of PT-1 as a closing
       condition and proceed with the STAR merger, the parties have agreed as
       follows:

        - the formula used to determine the exchange ratio will be modified by
          deleting "Z"; and

        - a holder of STAR common stock and STAR stock options or warrants will
          have the right to receive an additional number of "contingent" shares
          of World Access common stock (if and when the sale of PT-1 is
          completed, or in the case of a holder of stock options or warrants,
          when such stock option or warrant is exercised), equal to the net cash
          proceeds from the sale in excess of $150.0 million divided by 20; and

     - STAR must provide evidence satisfactory to World Access that all
       obligations of STAR relating to the China-U.S. Cable Network were fully
       satisfied by the reclamation of STAR's capacity in the network and that
       STAR has no further obligations or liabilities with respect to the
       network.

                                       91
<PAGE>   105

     STAR's obligations to complete the STAR merger and the other transactions
are subject to the satisfaction or waiver of each of the following additional
conditions before completion of the STAR merger:

     - World Access' representations and warranties must be true and correct as
       of February 11, 2000 and as of the date of the completion of the STAR
       merger, except to the extent the representations and warranties speak
       only as of a particular date and except where any failure to be true and
       accurate would not have a material adverse effect on World Access;

     - World Access must perform or comply in all material respects with all of
       its material agreements and covenants required by the STAR merger
       agreement to be performed or complied with at or before completion of the
       STAR merger;

     - all consents and approvals required of World Access to complete the STAR
       merger, the failure of which to obtain would have a material adverse
       effect on World Access or the surviving corporation, must be obtained.
       However, if the failure of STAR to use reasonable efforts to obtain such
       consents and approvals is the cause of the failure to obtain such
       consents and approvals, STAR must complete the STAR merger (assuming all
       other conditions to STAR's obligations are fulfilled or waived);

     - no material adverse effect with respect to World Access shall have
       occurred since February 11, 2000, 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 World Access operates and not
       relating specifically to World Access, or (iii) to the trading price of
       World Access common stock;

     - STAR must receive from World Access' legal counsel a legal opinion
       reasonably satisfactory to STAR;

     - no laws may be adopted or injunctions or orders issued by a court or
       other governmental entity having the effect of making the STAR merger
       illegal or prohibiting the completion of the STAR merger or which would
       otherwise have a material adverse effect on World Access. However, STAR
       must complete the STAR merger (assuming all other conditions to its
       obligations are fulfilled or waived) if its failure to use reasonable
       efforts to complete the STAR merger was the cause of, or resulted in, any
       such order or injunction; and

     - the exchange agent to be appointed pursuant to the STAR merger agreement
       must certify to STAR that the requisite deposit of cash in lieu of
       fractional shares and stock certificates to be made by World Access with
       the escrow agent has been made.

     A "material adverse effect" means, with respect to any entity, any change,
circumstance or effect or any breach of the provisions of the STAR merger
agreement that, individually or in the aggregate, is or would reasonably be
expected to be materially adverse to the business, financial condition or
results of operations of such entity and its subsidiaries, taken as a whole, or
the ability of such entity to complete the STAR merger.

TERMINATION OF THE STAR MERGER AGREEMENT

     The STAR merger agreement may be terminated at any time prior to completion
of the STAR merger for any of the following reasons:

     - by written consent of World Access and STAR;

     - by either World Access or STAR, if the other party fails to comply in any
       material respect with any of its material covenants or agreements in the
       STAR merger agreement, which failure to comply is uncured within ten
       business days following receipt of a notice of breach. However, if any
       breach is curable by the breaching party through the exercise of
       reasonable efforts, the non-breaching party may not terminate the STAR
       merger agreement for so long as the breaching party continues to use
       reasonable efforts to cure the breach. In addition, no party may
       terminate the

                                       92
<PAGE>   106

       STAR merger agreement if such party is then failing to comply in any
       material respect with any of its covenants or agreements in the STAR
       merger agreement;

     - by either World Access or STAR, if the other party has breached any of
       its representations or warranties, which breach is uncured within ten
       business days following receipt of a notice of breach. However, if any
       breach is curable by the breaching party through the exercise of
       reasonable efforts, the non-breaching party may not terminate the STAR
       merger agreement for so long as the breaching party continues to use
       reasonable efforts to cure the breach. In addition, no party may
       terminate the STAR merger agreement with respect to such breaches which
       would not have a material adverse effect on World Access or the surviving
       corporation;

     - by either World Access or STAR, if the STAR merger is not completed on or
       before September 30, 2000. However, no party may terminate the STAR
       merger agreement if the failure of the STAR merger to be completed by
       such date is caused by the failure of such party to fulfill any of its
       obligations under the STAR merger agreement and such failure to fulfill
       any of its obligations constitutes a breach of the STAR merger agreement;

     - by either World Access or STAR if any governmental entity has issued a
       final and nonappealable order, decree or ruling permanently enjoining or
       prohibiting the STAR merger or has failed to issue an order, decree or
       ruling (which failure to issue is final and nonappealable), which, in
       either case, is necessary to fulfill a party's obligation to complete the
       STAR merger. However, no party may terminate the STAR merger agreement if
       such party's failure to fulfill any obligation under the STAR merger
       agreement is the cause of such action or inaction by the governmental
       entity;

     - by World Access or STAR, if the stockholders of World Access or STAR fail
       to adopt the STAR merger agreement by the requisite vote, in each case
       upon the taking of a vote at a duly held meeting;

     - by World Access, if the STAR board of directors (prior to the STAR
       stockholders meeting) makes an adverse change in the STAR recommendation,
       as defined below, or approves or recommends a superior proposal;

     - by STAR, at any time prior to the STAR stockholders vote, upon three
       business days' prior notice to World Access, if its board of directors
       determines that an acquisition proposal is a superior proposal. However,
       STAR may not terminate the STAR merger agreement unless:

        - prior to termination, STAR negotiates with World Access regarding a
          revised proposal by World Access, if negotiations are requested 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 termination fee described below; or

     - by World Access, if:

        - either STAR or any of its material subsidiaries (i) commences a
          voluntary case under any applicable bankruptcy, insolvency or similar
          law or consents to the entry of an order for relief in an involuntary
          case under any such law, (ii) consents to the appointment of a
          receiver, liquidator, custodian, trustee or similar official of STAR
          or a subsidiary of STAR or for all or a material portion of the
          property or assets of STAR or a subsidiary of STAR or (iii) effects
          any general assignment of the benefit of creditors;

        - a governmental entity enters a decree or order for (i) relief of STAR
          or any of its material subsidiaries in an involuntary case under any
          applicable bankruptcy, insolvency or other similar law, (ii)
          appointment of a receiver, liquidator, custodian, trustee or similar
          official of STAR or a subsidiary of STAR or for all or a material
          portion of the property or assets of STAR or a subsidiary of STAR or
          (iii) the winding up or liquidation of the affairs of STAR or any of
          its

                                       93
<PAGE>   107

          material subsidiaries and, in each case, such decree or order remains
          unstayed and in effect for 30 consecutive days; or

        - there is an event of default under the anticipated credit agreements
          between World Access and STAR.

An "adverse change in the STAR recommendation" would occur if STAR withdraws,
modifies or materially qualifies, in any manner adverse to World Access, its
recommendation that the STAR stockholders adopt the merger agreement, or takes
any action or makes any statement in connection with the STAR stockholders
meeting materially inconsistent with such recommendation.

PAYMENT OF TERMINATION FEE

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

     - if the STAR merger agreement is terminated by STAR because the STAR board
       of directors determines that an acquisition proposal is a superior
       proposal, then STAR must pay the termination fee prior to termination of
       the STAR merger agreement;

     - 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, then STAR
       must pay the termination fee within three days following the termination
       of the STAR merger agreement; or

     - if the STAR merger agreement is terminated by World Access or STAR
       because the stockholders of STAR have not adopted the STAR merger
       agreement by the requisite vote and STAR enters into a definitive
       agreement with respect to a business combination, as defined below,
       within 12 months following termination, then STAR must pay the
       termination fee prior to or at the closing of the business combination.

     A "business combination" means:

     - a business combination or similar transaction involving STAR as a result
       of which (i) STAR's stockholders no longer own 65% of the voting
       securities of the surviving entity or any person owns at least 20% of the
       voting securities of the surviving entity or (ii) individuals comprising
       the STAR board of directors prior to the completion of the transaction do
       not constitute a majority of the board of directors of the surviving
       entity;

     - a sale, lease, exchange, transfer or other disposition (in one or a
       series of related transactions) of at least 50% of the assets of STAR and
       its subsidiaries, taken as a whole; or

     - the acquisition by a person of at least 20% of the common stock of STAR,
       whether by business combination, exchange offer or otherwise.

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 which requires further approval by the World Access and STAR
stockholders in accordance with law or the rules of any relevant stock exchange.

     World Access or STAR may, at any time prior to completion of the STAR
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 and waive compliance with
any of the agreements of the other party contained in the STAR merger agreement.

                         RELATED TRANSACTION AGREEMENTS

     This section of the joint proxy statement/prospectus describes agreements
related to the STAR merger agreement, including the voting agreements of
Christopher E. Edgecomb and Samer Tawfik and the anticipated STAR credit
agreements. While we 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.

EDGECOMB VOTING AGREEMENT

     World Access and Christopher E. Edgecomb have entered into a voting and
stock transfer restriction agreement, dated February 11, 2000, pursuant to which
Mr. Edgecomb agreed, among other things, to vote all of his shares of STAR
common stock in favor of the STAR merger and against any action that would
impede, delay, postpone, or would reasonably be expected to discourage, the STAR
merger, or that would result in a breach of a covenant or a representation or
warranty of STAR under the STAR merger agreement.

     Except in limited circumstances, until the earlier of the completion of the
STAR merger and the termination of the voting and stock transfer restriction
agreement, Mr. Edgecomb may not:

     - sell, hypothecate, transfer, pledge, encumber, assign or otherwise
       dispose of, a "transfer", or enter into any contract or understanding
       with respect to a transfer of, any of his shares of STAR common stock;

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

     - enter into any voting arrangement or understanding with respect to such
       shares; or

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

     For the longer of six months following the completion of the STAR merger
and such time as Mr. Edgecomb is a member of the World Access board of
directors, Mr. Edgecomb may not transfer, or enter into any contract or
understanding with respect to the transfer of, any of the shares of World Access
common stock issued to Mr. Edgecomb pursuant to the STAR merger agreement, or
trade or take any position, hedge or otherwise, with respect to such shares of
World Access common stock. If, at any time after six months and within 18 months
following the completion of the STAR merger, Mr. Edgecomb is otherwise permitted
and desires to take any such action, a "proposed action," he must provide notice
to World Access. World Access has the first right to assist in the private
disposition of the shares specified in the notice of a proposed action to an
"accredited investor" or "qualified institutional buyer," as such terms are
defined in the Securities Exchange Act of 1934, as amended. However, if World
Access is unable to arrange for such private disposition within 30 days, Mr.
Edgecomb may complete the proposed action.

     Subject to limitations, World Access has also agreed to provide Mr.
Edgecomb piggyback registration rights with respect to the shares of World
Access common stock issued to Mr. Edgecomb in the STAR merger and not publicly
saleable by Mr. Edgecomb under the Securities and Exchange Commission's Rule
144. However, in order to exercise these rights, Mr. Edgecomb must request the
inclusion in such registration of at least 25% of such shares or shares having a
value of at least $2.0 million.

     Subject to limited exceptions, Mr. Edgecomb also agreed to specific
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 agreed, among other things, to vote all of his shares of STAR common
stock in favor of the STAR merger and against any action that would

                                       95
<PAGE>   109

impede, delay, postpone, or would reasonably be expected to discourage, the STAR
merger, or that would result in a breach of a covenant or a representation or
warranty of STAR under the STAR merger agreement.

     Until the earlier of the completion of the STAR merger and the termination
of the voting and stock transfer restriction agreement, Mr. Tawfik may not:

     - sell, hypothecate, transfer, pledge, encumber, assign or otherwise
       dispose of, a "transfer," or enter into any contract or understanding
       with respect to a transfer of, any of his shares of STAR common stock,
       except that Mr. Tawfik is expressly permitted to transfer up to 2,430,000
       shares of his STAR common stock to unaffiliated third parties;

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

     - enter into any voting arrangement or understanding with respect to such
       shares; or

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

     For six months following the completion of the STAR merger, Mr. Tawfik may
not transfer, or enter into any contract or understanding with respect to the
transfer of, any of the shares of World Access common stock issued to Mr. Tawfik
pursuant to the STAR merger agreement, or trade or take any position, hedge or
otherwise, with respect to such shares of World Access common stock. If, at any
time after six months and within 18 months following the completion of the STAR
merger, Mr. Tawfik is otherwise permitted and desires to take any such action, a
"proposed action", he must provide notice to World Access. World Access has the
first right to assist in the private disposition of the shares specified in the
notice of a proposed action to an "accredited investor" or a "qualified
institutional buyer," as such terms are defined in the Securities Exchange Act
of 1934, as amended. However, if World Access is unable to arrange for such
private disposition within 30 days, Mr. Tawfik may complete the proposed action.

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

                                   PROPOSAL 2

                                 THE PT-1 SALE

     This section of the joint proxy statement/prospectus describes the proposed
sale by STAR of its wholly-owned subsidiary, PT-1, to a third party, subject to
the minimum requirements set forth in this joint proxy statement/prospectus,
including STAR's receipt of a sales price of at least $          , obtaining the
opinion of STAR's financial advisor in connection with the sale and approval by
the STAR board of directors of a definitive sale agreement containing terms that
the STAR board of directors determines to be in the best interests of STAR. This
section of the joint proxy statement/prospectus also describes the terms of a
letter of intent between STAR and PT-1 acquiror pursuant to which STAR
anticipates entering into a definitive agreement for the sale of PT-1. This
proposal is for the consideration of the STAR stockholders. While we believe
that the description covers the material terms of the proposed PT-1 sale and the
related transactions, this summary may not contain all of the information that
is important to you. You should carefully read this entire document and the
other documents we refer to for a more complete understanding of the PT-1 sale.

APPROVAL OF THE PT-1 SALE

     As a condition to World Access' obligation to complete the STAR merger,
STAR is required to sell its wholly-owned subsidiary, PT-1, for net cash
proceeds of at least $150.0 million. As of the date of this joint proxy
statement/prospectus, there can be no guarantee that completion of the sale of
PT-1 to PT-1 acquiror, or any other buyer, will satisfy this condition.

     STAR is seeking stockholder approval to proceed with the PT-1 sale to PT-1
acquiror, or in the event that STAR does not reach a definitive agreement with
PT-1 acquiror, to such other buyer and on such other terms as the STAR board of
directors shall subsequently approve, subject to the minimum requirements set
forth in this joint proxy statement/prospectus, including STAR's receipt of a
sales price of at least $       , obtaining the opinion of STAR's financial
advisor in connection with the sale and approval by the STAR board of directors
of a definitive sale agreement containing terms that the STAR board of directors
determines to be in the best interests of STAR.

     STAR has entered into the PT-1 letter of intent with PT-1 acquiror for the
sale of certain assets and the assumption of certain liabilities of PT-1 to PT-1
acquiror and STAR anticipates that it will enter into a definitive agreement
with PT-1 acquiror. This joint proxy statement/prospectus describes the PT-1
letter of intent in detail.

     The terms of the definitive agreement are subject to negotiation and may
differ substantially from the terms of the PT-1 letter of intent. If a
definitive agreement is reached with PT-1 acquiror, STAR will sell certain
assets of PT-1 to PT-1 acquiror for cash proceeds of $150.0 million dollars plus
the assumption of certain liabilities, subject to adjustment based on the net
worth of the assets of PT-1 on the closing date of the PT-1 sale. In the event
that STAR does not reach a definitive agreement with PT-1 acquiror, STAR will
seek other buyers for PT-1 with the aid of Kaufman Brothers, STAR's financial
advisor.

     In determining the minimum sale price range for PT-1, the STAR board of
directors consulted with STAR's management, counsel and financial advisors. In
making its determination, the STAR board of directors reviewed and analyzed the
historical financial results and future prospects of PT-1's operations and
assessed comparable valuations of businesses similar to those of PT-1 to the
extent that comparable
                                       97
<PAGE>   111

information was available. The STAR board of directors and management estimated
potential transaction values using standard industry methodologies as well as
subjective factors relating specifically to PT-1 and the reasons for its sale.
The industry standard methodologies included analysis of trading multiples of
comparable public companies, analysis of valuation multiples of transactions
involving comparable companies and discounted cash flow analysis.

     The estimates contained in such 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 such 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, such analyses and estimates are inherently subject to
substantial uncertainty. The analyses were only one of many factors considered
by the STAR board of directors in its evaluation of the sale of PT-1 and should
not be viewed as determinative of the view of the STAR board of directors or
management with respect to the consideration to be paid for the sale of PT-1.

     The STAR board of directors considers it essential to give management the
flexibility to consummate a sale of PT-1 in a timely manner. In connection with
the execution of a definitive purchase agreement with a buyer of PT-1, STAR will
request an opinion from Kaufman Brothers as to the fairness, from a financial
point of view, to STAR of the consideration to be received by STAR in the sale
of PT-1.

     Except as requested in this joint proxy statement/prospectus, STAR will not
solicit any further stockholder vote for the PT-1 sale. Accordingly, STAR
stockholders will not have the opportunity to vote on the definitive PT-1 sale
agreement.

BACKGROUND OF THE PT-1 SALE

     PT-1 constitutes 90% of the 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. STAR has entered into a letter
of intent with PT-1 acquiror to sell to PT-1 acquiror certain assets of PT-1,
including the assumption of certain liabilities, for cash proceeds of $150.0
million, subject to adjustment based on the net worth of the assets of PT-1 on
the closing date. In the event that STAR does not reach a definitive agreement
with PT-1 acquiror pursuant to the terms of the PT-1 letter of intent, STAR will
attempt to sell PT-1 to such other buyer and on such other terms as the STAR
board of directors shall subsequently approve, subject to the minimum
requirements set forth in this joint proxy statement/prospectus, including
STAR's receipt of a sales price of at least $       , obtaining the opinion of
STAR's financial advisor in connection with the sale and approval by the STAR
board of directors of a definitive sale agreement containing terms that the STAR
board of directors determines to be in the best interests of STAR. If STAR does
not receive net cash proceeds of at least $150.0 million from the PT-1 sale,
then World Access does not have to complete the STAR merger.

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

     On February 29, 2000, STAR engaged Kaufman Brothers, L.P., to act as its
exclusive financial and merger advisor and investment banker in connection with
the PT-1 sale. Kaufman Brothers reviewed the inquiries from potential acquirors
of PT-1 generated by the February 14, 2000 press release and proceeded to
familiarize 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
proposal was for the separate acquisition of PT-1's dial around business, the
second proposal was for PT-1's prepaid calling card operations, and the third
offer was made by PT-1 acquiror for the entire operations of PT-1. Working with
Kaufman Brothers, STAR

                                       98
<PAGE>   112

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 evidenced by the fact that the combined
value of the two offers for component business of PT-1 was less than the offer
STAR had received from PT-1 acquiror 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 PT-1 acquiror in New York to discuss
further PT-1 acquiror's interest in PT-1. Representatives and financial advisors
of STAR and PT-1 acquiror attended the meeting. At the meeting, PT-1 acquiror
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 PT-1 acquiror. STAR was unwilling to commit to an
exclusive arrangement at that time, but permitted PT-1 acquiror to begin due
diligence. On March 18, 2000, STAR met with PT-1 acquiror in Toronto, Canada, to
continue discussions. Following 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 resolved to continue
negotiations with PT-1 acquiror and to seek World Access' approval as required
by the STAR merger agreement. STAR and PT-1 acquiror executed the letter of
intent on March 29, 2000.

     On May   , 2000, the STAR board of directors met to consider the PT-1 sale.
At the meeting, the STAR board of directors concluded that the sale of PT-1 to
PT-1 acquiror pursuant to the terms of the PT-1 letter of intent, or in the
event that STAR did not reach a definitive agreement with PT-1 acquiror, to such
other buyer and on such other terms as the STAR board of directors shall
subsequently approve, subject to the minimum requirements set forth in this
joint proxy statement/prospectus, including STAR's receipt of a sales price of
at least $          , obtaining the opinion of STAR's financial advisor in
connection with the sale and approval by the STAR board of directors of a
definitive sale agreement containing terms that the STAR board of directors
determines to be in the best interests of STAR was fair to and in the best
interests of STAR and its stockholders. The STAR board of directors considered
numerous factors in reaching its conclusion, including the necessity of
completing the sale of PT-1 prior to and in connection with the close of the
STAR merger and considered the potential benefits of the PT-1 sale, including
relevant business, financial, legal and market factors, some of which are
discussed below under the heading "STAR's reasons for the PT-1 sale." The STAR
board of directors voted to approve the PT-1 sale and transactions contemplated
thereby and voted to recommend that the stockholders of STAR vote FOR the
approval of the PT-1 sale on such terms as the STAR board of directors shall
determine to be in the best interests of STAR and contingent on the negotiation
of a definitive agreement with PT-1 acquiror or such other buyer as the STAR
board of directors shall subsequently approve, subject to the minimum
requirements set forth in this joint proxy statement/prospectus, including
STAR's receipt of a sales price of at least $          , obtaining the opinion
of STAR's financial advisor in connection with the sale and approval by the STAR
board of directors of a definitive sale agreement containing terms that the STAR
board of directors determines to be in the best interests of STAR.

     Except as requested in this joint proxy statement/prospectus, STAR will not
solicit any further stockholder vote for the PT-1 sale. Accordingly, STAR
stockholders will not have the opportunity to vote on a definitive PT-1 sale
agreement.

STAR'S REASONS FOR THE PT-1 SALE

     At the meeting held on May   , 2000, the STAR board of directors concluded
that the PT-1 sale was fair to and in the best interests of STAR and its
stockholders. The board of directors of STAR voted to approve the PT-1 sale to
PT-1 acquiror or such other buyer as the STAR board of directors shall
subsequently approve, subject to the minimum requirements set forth in this
joint proxy statement/prospectus, including STAR's receipt of a sales price of
at least $          , obtaining the opinion of STAR's financial advisor in
connection with the sale and approval by the STAR board of directors of a
definitive sale agreement containing terms that the STAR board of directors
determines to be in the best

                                       99
<PAGE>   113

interests of STAR and voted to recommend that the stockholders of STAR vote for
the approval of the PT-1 sale and such transactions as may be contemplated
thereby.

     After due deliberation, the STAR board of directors concluded that the PT-1
sale to PT-1 acquiror or such other buyer as the STAR board of directors shall
subsequently approve, subject to the minimum requirements set forth in this
joint proxy statement/prospectus, including STAR's receipt of a sales price of
at least $          , obtaining the opinion of STAR's financial advisor in
connection with the sale and approval by the STAR board of directors of a
definitive sale agreement containing terms that the STAR board of directors
determines to be in the best interests of STAR, was fair to and in the best
interest of STAR and its stockholders based on a number of factors, including
the following:

          The PT-1 sale 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. If STAR fails to sell PT-1 for net cash proceeds
     of at least $150.0 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
     required the sale of certain non-core segments of STAR's operations. The
     PT-1 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 sale, STAR expects that the sale 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 sale of PT-1 would enable STAR to
     focus on its wholesale international long distance business and continue to
     expand its network in order to improve operating margins.

     The foregoing discussion of the information and factors considered by the
STAR board of directors is not intended to be exhaustive. In view of the wide
variety of factors considered in connection with its evaluation of the PT-1
sale, the STAR board of directors did not find it practical to, nor did it
attempt to, quantify, rank or otherwise attempt to assign relative weights to
the specific factors considered in reaching its determination. In addition, the
STAR board of directors did not undertake to make a specific determination as to
whether any particular factor was favorable or unfavorable to the board of
directors' ultimate determination or assign any particular weight to any factor,
but rather conducted an overall analysis of the factors described above,
including thorough discussion with and questioning of STAR's management and
management's analysis of the PT-1 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.

RECOMMENDATION OF THE STAR BOARD OF DIRECTORS

     The STAR board of directors has carefully considered the advisability of
the PT-1 sale and believes that the PT-1 sale and such transactions as may be
contemplated thereby are fair to and in the best interests of STAR and its
stockholders. THE STAR BOARD OF DIRECTORS HAS APPROVED THE PT-1 SALE AND SUCH
TRANSACTIONS AS MAY BE CONTEMPLATED THEREBY AND RECOMMENDS THAT THE STOCKHOLDERS
OF STAR VOTE FOR THE APPROVAL OF THE PT-1 SALE AND SUCH TRANSACTIONS AS MAY BE
CONTEMPLATED THEREBY.

                                       100
<PAGE>   114

CONSIDERATION TO BE RECEIVED IN THE PT-1 SALE

     STAR has entered into the PT-1 letter of intent with PT-1 acquiror pursuant
to which STAR has agreed to sell certain assets of PT-1 to PT-1 acquiror for
$150.0 million in cash provided that the purchase price may be adjusted upward
or downward to the extent that the net value of the purchased assets, less
liabilities assumed by PT-1 acquiror, as set forth on the balance sheet to be
delivered as soon as practicable following the closing, is greater than or less
than $37,223,490. PT-1 acquiror will only assume PT-1's (i) accounts payable and
accrued expenses, (ii) accrued taxes payable, (iii) short-term debt, (iv)
deferred revenue and (v) long-term debt. The terms of the definitive agreement
are subject to negotiation and may differ substantially from the terms of the
PT-1 letter of intent.

     In the event that STAR is unable to negotiate a definitive agreement with
PT-1 acquiror, STAR will proceed with the PT-1 sale to such other buyer and on
such other terms as the board of directors of STAR shall subsequently approve,
subject to STAR's receipt of a sales price of at least $          , obtaining
the opinion of STAR's financial advisor in connection with the sale and approval
by the STAR board of directors of the terms of any definitive sale agreement.
Except as requested in the accompanying joint proxy statement/prospectus, STAR
will not solicit any further stockholder vote for the PT-1 sale. Accordingly,
STAR stockholders will not have the opportunity to vote on a definitive PT-1
sale agreement.

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

     If STAR completes the sale of PT-1 to PT-1 acquiror, or another buyer on
terms like those set forth in the PT-1 letter of intent, for cash, the PT-1 sale
will be a taxable transaction to STAR. STAR expects that the net proceeds of the
PT-1 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 SALE

     If STAR completes the sale of PT-1's assets to PT-1 acquiror, or another
buyer for cash, the PT-1 sale will be accounted for by STAR 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.

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

     STAR anticipates that the PT-1 sale will be subject to the requirements of
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or HSR,
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. The HSR requirements will be satisfied if the PT-1 sale is completed
within one year from the termination of the waiting period.

     The Antitrust Division of the Department of Justice or the Federal Trade
Commission may challenge the PT-1 sale on antitrust grounds either before or
after expiration of the waiting period. Accordingly, at any time before the
completion of the PT-1 sale, either the Antitrust Division of the Department of
Justice or the Federal Trade Commission could take action under the antitrust
laws. Other persons could take action under the antitrust laws, including
seeking to enjoin the PT-1 sale. Additionally, at any time before or after the
completion of the PT-1 sale, 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 PT-1 sale under the antitrust laws
will not be made or that, if a challenge is made, it would not be successful.

RIGHTS OF DISSENTING STAR STOCKHOLDERS

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

INTERESTS OF CERTAIN PERSONS IN THE PT-1 SALE

     When considering the recommendation of the STAR board of directors, you
should be aware that certain STAR directors, officers and stockholders have
interests in the STAR merger, of which the PT-1 sale is a condition precedent,
that are different from, or are in addition to, all other stockholders of STAR.
These interests are described on page 85.

     Kaufman Brothers, STAR's financial advisor, has been engaged to issue a
fairness opinion to STAR's board of directors in connection with the PT-1 sale.
Upon consummation of the PT-1 sale, Kaufman Brothers will receive a transaction
fee equal to 1% of the PT-1 sales price. Regardless of whether the PT-1 sale is
consummated, STAR has agreed to reimburse Kaufman Brothers for reasonable fees
and disbursements of Kaufman Brothers' counsel and all of Kaufman Brothers'
reasonable travel and other out-of-pocket expenses incurred in connection with
the PT-1 sale.

                           THE PT-1 LETTER OF INTENT

     This section of the joint proxy statement/prospectus describes the terms of
the PT-1 letter of intent between STAR and PT-1 acquiror. While we believe that
the description covers the material terms of the PT-1 letter of intent, this
summary may not contain all of the information that is important to you. The
PT-1 letter of intent is attached to this joint proxy statement/prospectus as
Annex F and we urge you to read it carefully. There can be no guarantee that the
terms of a definitive agreement between STAR and PT-1 acquiror or any other
buyer will contain the terms set forth below.

NEGOTIATION OF DEFINITIVE AGREEMENT WITH PT-1 ACQUIROR

     STAR and PT-1 acquiror have agreed to proceed diligently and in good faith
to negotiate, execute and deliver definitive agreements in connection with the
sale of PT-1 to PT-1 acquiror. STAR has agreed to make all reasonable efforts to
facilitate PT-1 acquiror in certain aspects of negotiations with World Access
related to the PT-1 sale and in identifying and recruiting key officers and
employees of STAR and PT-1 for employment by PT-1 acquiror or the entity
operating the business of PT-1. In the event that STAR and PT-1 are unable to

TERMS OF THE DEFINITIVE AGREEMENT WITH PT-1 ACQUIROR

       of the applicable statute of limitations);

     - STAR and PT-1 acquiror will proceed diligently and in good faith to file
       all documents necessary to satisfy any applicable waiting period under
       the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended;

     - STAR will obtain all material third-party consents to the transactions
       contemplated by the PT-1 letter of intent, provided such condition may be
       waived by PT-1 acquiror in its sole discretion;

     - STAR shall use reasonable efforts to identify, with PT-1, key employees
       and to cause certain of STAR's key executives to enter into employment
       agreements and non-competition agreements with PT-1 acquiror; and

     - STAR shall cause PT-1 to conduct the business and operations of PT-1 in
       the ordinary course consistent with past practice.

DESCRIPTION OF THE PT-1 ASSETS

     PT-1 has agreed, on the terms set forth in the PT-1 letter of intent, to
sell to PT-1 acquiror all of the assets that relate to and are used in the debit
card and dial around businesses of PT-1 and PT-1's subsidiaries.

ASSUMPTION OF LIABILITIES

     Concurrently with its purchase of the assets of PT-1's debit card and dial
around telecom businesses, PT-1 acquiror will assume those liabilities itemized
on the balance sheet of PT-1 as of the closing date, as (i) accounts payable and
accrued expenses, (ii) accrued taxes payable, (iii) short-term debt, (iv)
defined revenue and (v) long-term debt.

respective businesses in the ordinary course and consistent with past practice.

NO OTHER NEGOTIATIONS INVOLVING THE PT-1 SALE

     STAR has agreed not to:

     - solicit, discuss or encourage any inquiries, offers or proposals which
       constitute or are reasonably likely to lead to an acquisition proposal;

<PAGE>   117

PAYMENT OF TERMINATION FEE

     Pursuant to the PT-1 letter of intent, if STAR fails or refuses to
consummate the PT-1 sale for any reason, other than the following, STAR will be
required to pay PT-1 acquiror a termination fee of $5.85 million in cash upon
demand:

     - the failure to obtain the necessary regulatory approvals for the PT-1
       sale;

     - the failure of a majority of STAR's stockholders entitled to vote to
       approve the transactions contemplated (provided that STAR does not sell
       the PT-1 assets to another purchaser within twelve months of such failure
       to approve the asset sale to PT-1 acquiror);

     - PT-1 acquiror's breach of the material terms of the PT-1 sale agreement;
       or

     - upon the mutual written consent of PT-1 acquiror and STAR.

agreement with PT-1 acquiror. The agreement will require Mr. Edgecomb, as a STAR
stockholder, to vote all shares of STAR common stock beneficially owned by him
in favor of the approval of the PT-1 sale. Mr. Edgecomb held approximately
[       %] of the outstanding capital stock of STAR as of the STAR record date.

                                   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.

     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 DLJ 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, DLJ 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

     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. After
consideration of relevant business, financial, legal and market factors, the
board of directors unanimously approved the WORLDxCHANGE merger agreement and
the transactions contemplated thereby and voted to recommend that the
stockholders of World Access vote FOR the approval and adoption of the
WORLDxCHANGE merger agreement and the transactions contemplated thereby.

     In deciding to approve the WORLDxCHANGE merger agreement and to recommend
approval and adoption of the WORLDxCHANGE merger agreement by the World Access
stockholders, the World Access board of directors considered a number of
factors, including particularly the factors listed 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 specific 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 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 DLJ 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. The directors also considered
their own knowledge of World Access and WORLDxCHANGE and their respective
businesses.

     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 of directors also
considered the technical capabilities, cost effectiveness, expansion
possibilities and available capacity of WORLDxCHANGE's switches in multiple
countries,

                                       105
<PAGE>   119

ownership interest in undersea cable systems, IRUs in additional undersea cable
systems comprising more than 370 E-1 circuits and seven satellite earth stations
in the U.S. and abroad.

     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. The board of
directors also considered the importance of market position in the global
telecommunications services industry. 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
interconnection agreements in Belgium, Chile, France, Germany and Guatemala in
light of potential expansion.

     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.

RECOMMENDATION OF THE WORLD ACCESS BOARD OF DIRECTORS

     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 THEREBY AND UNANIMOUSLY RECOMMENDS THAT THE
STOCKHOLDERS OF WORLD ACCESS VOTE FOR THE APPROVAL AND ADOPTION OF THE
WORLDXCHANGE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY.

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;

     - 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 a number of factors,
including:

     - historical information concerning World Access' and WORLDxCHANGE's
       respective businesses, financial performance and condition, operations,
       management and competitive position;

                                       106
<PAGE>   120

     - WORLDxCHANGE management's assessment of the business and financial
       prospects of World Access and WORLDxCHANGE as a combined company. In this
       regard, the WORLDxCHANGE board considered financial market and industry
       conditions and the potential synergies and opportunities for growth
       inherent in a combined company. In light of these factors, the
       WORLDxCHANGE board concluded that the long-term business and financial
       prospects of a combined company were superior to those of WORLDxCHANGE as
       an independent company;

     - the terms and conditions of the WORLDxCHANGE merger agreement, which the
       WORLDxCHANGE board believes to be fair, and in the best interests of, the
       WORLDxCHANGE shareholders;

     - WORLDxCHANGE's prior experience with other potential acquirors or
       strategic partners;

     - the ability of WORLDxCHANGE, as an independent company, to meet its near-
       and longer-term operating cash needs and fund capital expenditures
       necessary to achieve future growth;

     - the current and historical market prices and trading information with
       respect to World Access' common stock; and

     - the impact of the WORLDxCHANGE merger on WORLDxCHANGE's customers and
       employees.

     The WORLDxCHANGE board also considered certain potentially negative factors
in assessing the proposed WORLDxCHANGE merger. These factors include:

     - the risk that the value of World Access' common stock to be received at
       the closing of the WORLDxCHANGE merger would be less than the value of
       the World Access common stock reflected in the WORLDxCHANGE merger
       exchange ratio due to potential declines in the trading price of World
       Access' shares;

     - the risk that the WORLDxCHANGE merger will not be completed in a timely
       manner or at all and the effect of the public announcement on
       WORLDxCHANGE's ability to attract and retain key employees; and

     - the risk that a strategic alternative more favorable to the WORLDxCHANGE
       merger will be presented or become available to WORLDxCHANGE prior to the
       closing of the WORLDxCHANGE merger, which alternative WORLDxCHANGE would
       be prohibited from pursuing under the terms of the WORLDxCHANGE merger
       agreement.

     The above factors are not intended to represent an exhaustive list of all
of the factors considered by the WORLDxCHANGE board. However, they are believed
to include all of the material factors considered. In light of the variety of
factors considered, the WORLDxCHANGE board did not find it practicable to, and
did not, quantify or otherwise assign relative weight to any one or more of the
factors it considered in reaching its determination. In addition, individual
WORLDxCHANGE directors may have given different weights to different factors.
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

     The board of directors of World Access engaged DLJ to act as its financial
advisor in connection with the WORLDxCHANGE merger. On February 11, 2000, DLJ
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 of view. As described above under "World
Access' reasons for the WORLDxCHANGE merger," DLJ's opinion was

                                       107
<PAGE>   121

only one of many factors taken into consideration by the board of directors of
World Access in making its determination to approve the WORLDxCHANGE merger
agreement.

     THE FULL TEXT OF DLJ'S OPINION IS INCLUDED AS ANNEX D TO THIS JOINT PROXY
STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. STOCKHOLDERS ARE
URGED TO READ CAREFULLY DLJ'S OPINION IN ITS ENTIRETY FOR THE DESCRIPTIONS OF
THE PROCEDURES FOLLOWED, ASSUMPTIONS MADE, OTHER MATTERS CONSIDERED AND
LIMITATIONS OF THE REVIEW UNDERTAKEN IN ARRIVING AT THE OPINION. DLJ'S OPINION
WAS PREPARED FOR AND ADDRESSED TO WORLD ACCESS' BOARD OF DIRECTORS AND ONLY
ADDRESSES THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE CONSIDERATION TO
BE PAID BY WORLD ACCESS. DLJ'S OPINION DOES NOT:

     (1) ADDRESS THE MERITS OF THE UNDERLYING DECISION BY WORLD ACCESS TO ENGAGE
         IN THE WORLDXCHANGE MERGER OR OTHER BUSINESS STRATEGIES CONSIDERED BY
         WORLD ACCESS;

     (2) CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW THAT
         STOCKHOLDER SHOULD VOTE AT THE STOCKHOLDERS' MEETING; OR

     (3) CONSTITUTE AN OPINION AS TO THE PRICE AT WHICH WORLD ACCESS COMMON
         STOCK WILL ACTUALLY TRADE AT ANY TIME.

     The type and amount of consideration was determined in arms-length
negotiations between World Access and WORLDxCHANGE. No restrictions or
limitations were imposed by World Access upon DLJ with respect to the
investigations made or the procedures followed by DLJ in rendering its opinion.

     In arriving at its opinion, DLJ, among other things:

     - reviewed the draft, dated February 10, 2000, of the WORLDxCHANGE merger
       agreement and assumed that the final form of that agreement would not
       vary in any respect that would be material to DLJ'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; and

     - compared selected 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 and WORLDxCHANGE, reviewed prices
       paid in selected other business combinations and conducted other
       financial studies, analyses and investigations as DLJ deemed appropriate
       for purposes of its opinion.

     In rendering its opinion, DLJ 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. DLJ
relied upon the estimates of the management of World Access of the operating
synergies achievable as a result of the WORLDxCHANGE merger. DLJ 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. DLJ
expressed no opinion with respect to such forecasts or the assumptions on which
they were based, and DLJ 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
DLJ. DLJ also did not assume any responsibility for making any independent
investigation of any legal matters affecting World Access or WORLDxCHANGE 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
WORLDxCHANGE merger. DLJ assumed that the WORLDxCHANGE merger would be accounted
for as a pooling of interests under generally accepted accounting principles and
that it would qualify as a tax-free reorganization for U.S. federal income tax
purposes.

                                       108
<PAGE>   122

     The preparation of a fairness opinion is a complex process that is not
necessarily susceptible to partial analysis or summary description and involves
determinations about the most appropriate and relevant methods of financial
analysis and the application of these methods to the particular circumstances.
DLJ performed each of the analyses summarized below in order to provide a
different perspective on the WORLDxCHANGE merger and add to the total mix of
information available. However, although the separate analyses are summarized
below, DLJ believes that its analyses must be considered as a whole. Selecting
portions of the analyses or of the summary set forth below, without considering
the analyses as a whole, could create an incomplete or misleading view of the
processes underlying DLJ's opinion. DLJ 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 and did not attempt to
assign specific weights to particular analyses or factors considered. Rather, in
arriving at its opinion, DLJ considered the results of each of these analyses
together, in their totality and in light of each of the other analyses and made
qualitative judgements as to the significance and relevance of all of the
factors and analyses considered in arriving at its opinion.

     In performing its analyses, DLJ made numerous assumptions with respect to
industry performance, business and regulatory, financial, economic, monetary,
political and market conditions and other matters, many of which are beyond the
control of World Access or WORLDxCHANGE. In addition, analyses relating to the
value of businesses or securities are not appraisals and do not reflect the
prices at which the businesses or securities can actually be sold. Stockholders
should understand that no company or transaction used in DLJ's analyses as a
comparison is directly comparable to World Access, WORLDxCHANGE or the
WORLDxCHANGE merger. It should also be understood that analyses based upon
projections or forecasts of future results are not necessarily indicative of
actual future results, which may be significantly more or less favorable than
suggested by those analyses. Because these analyses are inherently subject to
uncertainty, being based upon numerous factors or events beyond the control of
the parties, none of World Access, WORLDxCHANGE or DLJ or any other person
assumes responsibility if future results are different from those forecast. See
"RISK FACTORS" elsewhere in this joint proxy statement/prospectus.

     DLJ's opinion is necessarily based upon economic, market, financial and
other conditions as they existed on, and on information available to DLJ as of,
the date of its opinion. It should be understood that, although subsequent
developments may affect its opinion, DLJ does not have any obligation to update,
revise or reaffirm its opinion as a result of changes in such conditions or
otherwise.

     The following is a brief summary of the principal analyses performed by DLJ
in connection with DLJ's opinion and included in its presentation to World
Access' board of directors. For purposes of the following analyses, DLJ used the
February 9, 2000 closing price of the World Access common stock of $22.88 per
share. It should be understood that DLJ makes no prediction, and there can be no
assurance, as to what the closing price of World Access common stock will
actually be.

     Included in the discussion below are summaries of some of the statistical
information appearing in that discussion presented in a tabular format. While
these tables are presented for the purpose of clarity and ease of reference,
they are not substitutes for, and must be read along with, all of the
information appearing under the captions immediately preceding them as well as
all of the information set forth in this document.

1. CONSIDERATION PAID ANALYSIS

     DLJ 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 (the "Initial
Exchange Ratio") for the ten-day period ending at the close of trading on the
second trading day preceding the closing (the "Averaging 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
(the "Maximum Exchange Ratio"). In reviewing the consideration to be

                                       109
<PAGE>   123

paid by World Access, DLJ 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 COMPANY ANALYSIS

     To provide comparative market information, DLJ compared selected historical
and projected operating and financial ratios of WORLDxCHANGE to the
corresponding data and ratios of selected publicly traded companies that operate
businesses reasonably similar to WORLDxCHANGE.

     For purposes of these analyses, DLJ compared WORLDxCHANGE relative to the
following five companies deemed by DLJ to be reasonably comparable to
WORLDxCHANGE:

<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>

     However, no company utilized in DLJ's analysis of comparable publicly
traded companies is identical to World Access or WORLDxCHANGE. Accordingly, this
analysis necessarily involves complex considerations and judgments concerning
differences in financial and operating characteristics of each of World Access
and WORLDxCHANGE and other factors that could affect the public trading values
of World Access, WORLDxCHANGE or any other comparable company included in this
analysis.

     Historical financial information used with respect to the comparable
companies was as of the most recent financial statements publicly available for
each company as of February 9, 2000. DLJ examined certain publicly available
financial data of the comparable companies including enterprise value (defined
as market value of common equity plus book value of total debt and preferred
stock less cash) as multiples of the latest publicly available last quarter
annualized revenues, estimated 2000 revenues taken from various analysts
research reports, gross property, plant and equipment and net property, plant
and equipment.

     DLJ 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 at
February 9, 2000. For purposes of this analysis, DLJ 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, DLJ 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
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.

(1) In comparing the ratio of WORLDxCHANGE's enterprise value (based on the
    Initial Exchange Ratio) to its last quarter annualized revenues, estimated
    2000 revenues, gross property, plant and equipment and net property, plant
    and equipment to those of the comparable companies at February 9, 2000, DLJ
    also determined a reference range for the comparable companies. The
    reference range represents a tighter range of the ratios as deemed
    reasonable by DLJ for comparative purposes.

     - IDT Corporation:  Lazard Freres research report dated December 6, 1999;

     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

     DLJ reviewed selected mergers and acquisitions transactions of companies
that operate businesses reasonably similar to that of WORLDxCHANGE. Of these
selected M&A transactions, the following mergers and acquisitions transactions
were deemed most relevant by DLJ:

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

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

     However, no company, transaction or business utilized in DLJ's analysis of
selected M&A transactions is identical to World Access, WORLDxCHANGE or the
WORLDxCHANGE merger. Accordingly, this analysis necessarily involves complex
considerations and judgments concerning differences in financial and operating
characteristics of companies and other factors that could affect the
acquisition, public trading or other values of the companies or transactions
being analyzed.

     DLJ performed this analysis in order to compare WORLDxCHANGE's ratios of
the implied transaction value (based on the Initial Exchange Ratio) to its last
quarter annualized revenues and net property, plant and equipment to those of
the selected mergers and acquisitions transactions. In addition, DLJ compared
the transaction value of WORLDxCHANGE (based on the Initial Exchange Ratio) to
the implied transaction values obtained by the above mentioned ratios of the
selected mergers and acquisitions transactions and WORLDxCHANGE's last quarter
annualized revenues and net property, plant and equipment.

* For purposes of this analysis, DLJ compared WORLDxCHANGE's ratios of the
  implied transaction value (based on the Initial Exchange Ratio) to its last
  quarter annualized revenues and net property, plant and equipment to those of
  the selected mergers and acquisitions transactions deemed most relevant by
  DLJ. In addition, DLJ compared the transaction value of WORLDxCHANGE (based on
  the Initial Exchange Ratio) to the implied transaction values obtained by the
  above mentioned ratios of the selected mergers and acquisitions transactions
  deemed most relevant by DLJ and WORLDxCHANGE's last quarter annualized
  revenues and net property, plant and equipment.

     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, DLJ 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. DLJ 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. DLJ calculated
EBITDA for WORLDxCHANGE. EBITDA is earnings before interest, taxes, depreciation
and amortization and other items. DLJ calculated the terminal value of
WORLDxCHANGE at the end of the forecast period, by applying a range of estimated
EBITDA multiples selected in DLJ'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 DLJ's subjective estimate of
the terminal values based on management's projected EBITDA were then discounted
to the present using a range of discount rates selected in DLJ's subjective
judgment.

     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 is not a complete description of the analyses
performed by DLJ, but describes, in summary form, the principal elements of the
analyses made by DLJ in arriving at DLJ's opinion. The preparation of a fairness
opinion involves 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 summarized.

  ENGAGEMENT LETTER

     World Access selected DLJ to render an opinion in connection with the
WORLDxCHANGE merger based upon DLJ's qualifications, expertise and reputation,
including the fact that DLJ, as part of its investment banking business, is
regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, underwritings, sales and distributions
of listed and unlisted securities, private placements and valuations for
corporate and other purposes.

     Pursuant to the terms of an engagement letter dated January 18, 2000, World
Access agreed to pay DLJ a fee of $850,000 at the time that DLJ delivered to the
World Access board of directors its opinion, irrespective of the conclusion
reached in the opinion, and to pay DLJ 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 DLJ for all of its out-of-pocket expenses, including the
reasonable fees and expenses of counsel incurred by DLJ in connection with its
engagement, and to indemnify DLJ for liabilities and expenses arising out of
DLJ's engagement, including liabilities under federal securities laws.

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

     DLJ provides a full range of financial, advisory and brokerage services and
in the course of its normal trading activities may from time to time effect
transactions and hold positions in the securities or debt of World Access for
its own account and for the accounts of its customers. DLJ has performed
investment banking and other services for World Access in the past and has been
compensated for such services. DLJ acted as financial advisor to World Access in
connection with its acquisition of FaciliCom International, Inc., and acted as
solicitation agent in connection with the consent solicitation for FaciliCom's
outstanding senior notes. DLJ is currently acting as financial advisor to World
Access in connection with its proposed acquisition of STAR. Further, DLJ is
currently providing advisory services in connection with the exploration of a
possible sale of World Access' NACT Telecommunications Inc. and Telco Systems
Inc. subsidiaries and World Access' Wireless Local Loop Division.

CONSIDERATION TO BE RECEIVED 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.

                                       114
<PAGE>   128

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.

CERTAIN MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE WORLDXCHANGE MERGER

     The following is a summary of certain 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, as disclosed herein, to the
extent the following discussion summarizes matters of law or legal conclusions,
it is accurate in all material respects under the federal income tax laws as now
in effect. The following discussion is general in nature and does not purport to
be 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 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: (i) an insurance company; (ii) a
tax-exempt organization; (iii) an employee stock ownership plan; (iv) a bank;
(v) a broker, dealer or financial institution; (vi) 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; (vii) a
holder that has a "functional currency" other than the United States dollar;
(viii) a holder subject to the alternative minimum tax; (ix) 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; (x) 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 (xi) 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 (for example, 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 summary assumes that as a
WORLDxCHANGE shareholder, you hold your WORLDxCHANGE capital stock as a "capital
asset" (generally, property held for investment) within the meaning of Section
1221 of the Internal Revenue Code of 1986, as amended, or the Code. This summary
is based on the Code and final, temporary and proposed treasury regulations
promulgated thereunder, 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 summary.

     We have not requested a ruling from the IRS with respect to the federal
income tax consequences of the WORLDxCHANGE merger nor is consummation 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 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 accuracy of
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 tax discussion
set forth below.

     The opinion represents such counsel's best judgment as to the tax treatment
of the WORLDxCHANGE merger, but neither binds the IRS nor precludes it from
adopting a contrary position, and no assurance can be given that contrary
positions will not be successfully asserted by the IRS 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 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
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.  Under Section
354 of the Code, 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 IRS as a dividend
distribution to you under Section 301 of the Code, 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 IRS, the cash you receive in lieu of a fractional share interest in World
Access common stock will be treated as received in "exchange" for such
fractional share interest under Section 302(a) of the Code. You will recognize
gain or loss measured by the difference between the amount of cash received and
the portion of the tax basis of

                                       116
<PAGE>   130

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 agreed upon 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 under
Section 354 of the Code. Upon a return of any such shares to World Access, your
tax basis in your pro rata share of the returned 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 under Section
354 of the Code 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 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 (the
"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 IRS 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 under Section 354 of the Code. Moreover, dividends
have not been declared on any of the shares of the WORLDxCHANGE preferred stock
and will not be declared as of the effective time of the WORLDxCHANGE merger,
and, in general, which 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 IRS 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

                                       117
<PAGE>   131

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 IRS 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 under Section 301 of the Code, and therefore taxable as
ordinary income to the extent of your allocable portion of the accumulated
earnings and profits (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"
under Section 243 of the Code, and may possibly be subject to the "extraordinary
dividend" provisions of Section 1059 of the 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 IRS 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 IRS has been sought nor has any opinion of tax counsel been issued
regarding this issue. 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 IRS.

     Cash received by dissenting WORLDxCHANGE shareholders.  Cash received by
WORLDxCHANGE shareholders who exercise appraisal rights will be treated as
having been received in redemption of your WORLDxCHANGE common stock, subject to
the provisions and limitations of Section 302 of the Code. If, as a result of
such redemption, you own no World Access stock either directly or through the
application of the stock ownership attribution rules of Section 318 of the Code,
then "exchange" treatment occurs under Section 302(a) of the Code. If exchange
treatment applies, 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 IRS 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.

  Tax considerations for the corporate parties

     World Access, WORLDxCHANGE Communications, Inc. f/k/a CTI Merger Co. and
WORLDxCHANGE.  No gain or loss will be recognized by World Access, WORLDxCHANGE
Communications, Inc. f/k/a CTI Merger Co., or WORLDxCHANGE as a result of the
WORLDxCHANGE merger. However, 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" within the meaning of Section 280G of the
Code. Excess parachute payments are not deductible in accordance with Section
280G. No determination can be made at this time whether any amounts will be
determined to be excess parachute payments, and therefore, Long Aldridge &
Norman LLP has expressed no opinion with respect to this matter.

     Limitation on WORLDxCHANGE tax attributes.  Under Section 381 of the Code,
WORLDxCHANGE Communications, Inc. f/k/a CTI Merger Co. will succeed to the net
operating losses ("NOLs"), 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 Sections 381, 382, 383,
384 of the 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" (the "SRLY") rules. Under Section 382 of the Code, special
limitations apply after an "ownership change" to the use of NOLs and "net
unrealized built-in losses" in excess of a threshold amount recognized during
the five-year period after such ownership change. 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 NOLs 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 IRS (5.84% for May 2000). The Section 382 limitation
for any post-ownership change year will generally be zero unless the loss
corporation satisfies a "continuity of business enterprise" requirement for the
two-year period following the ownership change.

     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. f/k/a CTI Merger Co.
as WORLDxCHANGE's corporate successor) will constitute a "loss subgroup" which
will undergo a Section 382 ownership change upon consummation of the
WORLDxCHANGE merger. Consequently, the World Access consolidated group's ability
to utilize such loss subgroup's NOL carryover as of September 30, 1999, and any
additional loss subgroup's NOL carryover of such loss subgroup arising in
WORLDxCHANGE's fiscal year beginning October 1, 1999 during the period prior to
the effective time of the WORLDxCHANGE merger (collectively, the "pre-change
WORLDxCHANGE loss subgroup NOLs") against future World Access consolidated
federal taxable income will be subject to an annual loss subgroup Section 382
limitation. If there is a prior Section 382 limitation, then successive
ownership changes may result in an additional, lesser (but never in a greater)
Section 382 limitation with respect to previously limited NOLs.

     An additional limitation may apply under which the pre-change WORLDxCHANGE
loss subgroup NOLs can only be used to the extent of the "qualifying SRLY
subgroup" members' aggregate, cumulative contribution to World Access
consolidated taxable income (the "SRLY limitation"). Because the WORLDxCHANGE
loss subgroup and its SRLY NOL subgroup should be treated as co-extensive, and
the Section 382 ownership change and SRLY event will occur at the same time, the
SRLY limitation should be eliminated with respect to the WORLDxCHANGE loss
subgroup NOLs. However, the WORLDxCHANGE subgroup for built-in losses may not be
co-extensive with the WORLDxCHANGE loss subgroup and its SRLY NOL subgroup and,
if not, then if such WORLDxCHANGE subgroup built-in losses exceed a specified
threshold amount, such built-in losses recognized during the five-year period
following the SRLY event may still be subject to limitation under the SRLY
rules.

     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 NOL, and has a
consolidated NOL carryover. As such, it constitutes a "loss group." Although it
is currently unclear whether the World Access loss group will undergo a Section
382 ownership change as a result of consummating either or both the WORLDxCHANGE
merger and the STAR merger, 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 NOL carryover as of December 31, 1999, and
certain "recognized built-in losses" against its future consolidated federal
taxable income may already be subject to an annual loss group Section 382
limitation.

                                       119
<PAGE>   133

     If consummation 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 NOLs 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.

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 (i) an effective
registration statement under the Securities Act of 1933 covering the resale of
those shares, (ii) Rule 145 under the Securities Act of 1933 or (iii) 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, or HSR, which
prevents transactions from being completed until

                                       120
<PAGE>   134

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 HSR 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 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 FCC
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 FCC. 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
FCC 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

                                       121
<PAGE>   135

Corporation Law, or the CGCL. This summary is not a complete statement of the
law relating to dissenters' rights and is qualified in its entirety by reference
to the full text of Chapter 13 of the CGCL. A copy of Chapter 13 of the CGCL is
attached as Annex I to this joint proxy statement/prospectus and is incorporated
herein by reference. Failure to comply with the procedures set forth in Chapter
13 of the CGCL will result in the loss or waiver of dissenters' rights.
Therefore, this discussion and Chapter 13 of the CGCL 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 who complies with the provisions and
procedures of Chapter 13 of the CGCL, 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 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 in consequence of the
proposed WORLDxCHANGE merger (i.e., valuing the WORLDxCHANGE shares as if the
WORLDxCHANGE merger had not occurred) but adjusted for any stock split, reverse
stock split or share dividend that becomes effective thereafter. A failure to
vote affirmatively against the WORLDxCHANGE merger will not constitute a waiver
of dissenters' rights set forth in Chapter 13 of the CGCL. 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 WORLDxCHANGE
merger.

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

     To qualify as a dissenting share under the CGCL, 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 ten days after the date of the approval of
the WORLDxCHANGE merger by the required WORLDxCHANGE shareholder vote or consent
to mail a notice of the approval of the WORLDxCHANGE 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 CGCL, 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 such dissenting
shareholder's shares. WORLDxCHANGE must receive such 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

                                       122
<PAGE>   136

mailed to dissenting shareholders. The demand must set forth the number and
class of shares held of record by such shareholder 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 WORLDxCHANGE merger. The statement of fair
market value in such demand by the dissenting shareholder constitutes an offer
by the shareholder to sell the shares at such 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, such dissenting
shareholder must also submit to WORLDxCHANGE at its principal office or the
office of any transfer agent thereof share certificates representing any
dissenting shares that the dissenting shareholder demands that WORLDxCHANGE
purchase, so that such dissenting shares may either be stamped or endorsed with
the statement that the shares are dissenting shares or 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. Such 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
consummation 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/or whether the shares qualify as dissenting shares.

     The costs and expenses of the action, including reasonable compensation to
the appraisers, will be fixed and shall be assessed or apportioned as the court
considers equitable, but, 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 CGCL and Section 1306 of the CGCL,
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 the above mentioned provisions of the CGCL prohibit cash
payments to holders of dissenting shares who exercise and perfect their
dissenters' rights of their fair market value, such dissenting shareholders will
become creditors of WORLDxCHANGE for an amount equal to the fair market value of
their shares as to which the dissenters' rights are perfected plus interest
accrued thereon at the legal rate on judgments until the date of payment. The
rights of such dissenting shareholders, however, will be subordinate to the
rights of all other creditors of WORLDxCHANGE in any liquidation proceeding,
with such 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 CGCL fails to perfect, or effectively withdraws or loses his,
her or its right to such purchase, the shares of such

                                       123
<PAGE>   137

holder will be converted into a right to receive the applicable merger
consideration with respect thereto in accordance with the terms of the
WORLDxCHANGE merger agreement.

     Dissenting shares lose their status as dissenting shares, and the holders
of dissenting shares cease to be dissenting shareholders and cease to be
entitled to require WORLDxCHANGE to purchase their shares if:

     - the WORLDxCHANGE merger is abandoned, in which case WORLDxCHANGE shall
       pay on demand to any dissenting shareholder who has initiated proceedings
       in good faith under Chapter 13 of the CGCL all necessary expenses
       incurred in such 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 such request for withdrawal.

     FAILURE TO FOLLOW THE STEPS REQUIRED BY CHAPTER 13 OF THE CGCL 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 WITH RESPECT TO SUCH DISSENTING SHARES IN ACCORDANCE WITH THE
WORLDXCHANGE MERGER AGREEMENT). IN VIEW 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 CERTAIN PERSONS IN THE WORLDXCHANGE MERGER

     Under the terms of the WORLDxCHANGE merger agreement, World Access has
agreed to cause one designee of WORLDxCHANGE to be elected to the World Access
board of directors. 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 record date for determining the WORLDxCHANGE shareholders
entitled to approve the WORLDxCHANGE merger, executive officers and directors of
WORLDxCHANGE and Gold & Appel Transfer S.A. and Atocha, L.P. collectively
beneficially owned a total of           shares of WORLDxCHANGE common stock (not
including any shares subject to outstanding options or warrants beneficially
owned by these individuals or entities). Under the WORLDxCHANGE merger
agreement, these shares will be converted in the WORLDxCHANGE merger into a
total of           shares of World Access common stock with an aggregate value
of $       (assuming a per share value of World Access common stock equal to
$20.38). In addition to the foregoing, WORLDxCHANGE executive officers and
directors and Gold & Appel Transfer S.A. and Atocha, L.P. beneficially owned
options and warrants to purchase an aggregate of           shares of
WORLDxCHANGE common stock. These options and

                                       124
<PAGE>   138

warrants had exercise prices ranging from $       to $       per share. Pursuant
to the WORLDxCHANGE merger agreement, these options and warrants, to the extent
not exercised as of immediately prior to the WORLDxCHANGE merger, will be
converted into the right to acquire shares of World Access common stock in
accordance with the WORLDxCHANGE merger agreement. Each of Roger Abbott, Chief
Executive Officer and a director of WORLDxCHANGE, and Edward Soren, Executive
Vice President and a director of WORLDxCHANGE, have agreed with World Access to
vote his shares in favor of the WORLDxCHANGE merger. In addition, affiliates of
Walter Anderson, WORLDxCHANGE's Chairman of the board, and Thomas Cirrito, a
WORLDxCHANGE director, have agreed with World Access to vote their shares in
favor of the WORLDxCHANGE merger.

     Each of Mr. Abbott, Mr. Soren, Gold & Appel Transfer S.A. and Atocha L.P.
has agreed in his or its voting and stock transfer restriction agreement with
World Access not to sell or otherwise transfer the World Access shares received
by him or it in the WORLDxCHANGE merger until six months after the completion of
the WORLDxCHANGE merger. However, Mr. Soren's agreement permits Mr. Soren
immediately to sell up to 750,000 shares of World Access common stock to be
received by Mr. Soren in the WORLDxCHANGE merger without restriction. In
addition, Mr. Abbott's agreement permits Mr. Abbott immediately to sell such
number of shares of World Access common stock to be received by Mr. Abbott in
the WORLDxCHANGE merger as would provide Mr. Abbott with aggregate gross cash
proceeds of up to $30.0 million. In no event will Mr. Abbott be permitted to
sell more than $30.0 million worth of World Access common stock received by him
in the WORLDxCHANGE merger prior to the expiration of the six-month transfer
restriction period under his voting and stock transfer restriction agreement
with World Access.

     Under Mr. Abbott's employment agreement with WORLDxCHANGE, if, in
connection with a change of control of WORLDxCHANGE or otherwise, Mr. Abbott's
employment with WORLDxCHANGE is terminated other than for cause, death or
disability, or if Mr. Abbott's employment is constructively terminated, Mr.
Abbott will be entitled to:

     - the payment of any earned but unpaid salary and/or bonus under the
       agreement; and

     - a lump sum cash payment in an amount equal to the amount he would have
       earned under the agreement from the date of termination through July 31,
       2002 (currently $50,000 per month) plus the cost for Mr. Abbott to obtain
       benefits equivalent to those in effect at the time of the termination
       through July 31, 2002.

Mr. Abbott's employment agreement defines "cause" to include:

     - Mr. Abbott's conviction of a felony;

     - fraudulent conduct by Mr. Abbott in connection with the business of
       WORLDxCHANGE; and

     - Mr. Abbott's bad faith refusal to perform his duties as WORLDxCHANGE's
       Chief Executive Officer.

Mr. Abbott's employment agreement defines "constructive termination" as:

     - a material reduction in the kind or level of Mr. Abbott's employee
       benefits;

     - the relocation of Mr. Abbott to a location more than 40 miles from
       WORLDxCHANGE's current offices in San Diego without Mr. Abbott's prior
       consent;

     - the failure of WORLDxCHANGE to have Mr. Abbott's employment agreement
       assumed by any successor entity; or

     - any circumstances which would constitute a constructive termination of
       Mr. Abbott's employment under California law.

The WORLDxCHANGE merger would constitute a change of control of WORLDxCHANGE
under Mr. Abbott's employment agreement.

     Patrick Aelvoet, WORLDxCHANGE's Chief Financial Officer, has an employment
agreement with WORLDxCHANGE that provides for the payment of a $50,000 severance
payment to Mr. Aelvoet if, in connection with a change of control of
WORLDxCHANGE or otherwise, WORLDxCHANGE terminates Mr. Aelvoet's employment
without cause and without at least 90 days' advance notice of such termination.
Mr. Aelvoet's employment agreement defines "cause" to include:

     - personal dishonesty;

     - incompetence;

     - willful misconduct;

     - abandonment of employment or extensive absences;

     - conflict of interest or breach of fiduciary duty involving intent for or
       obtainment of material personal or family profit;

     - violation of any law (other than minor traffic offenses and the like);

     - a court order prohibiting Mr. Aelvoet's continued employment with
       WORLDxCHANGE;

     - a final cease-and-desist order issued by a regulatory agency; or

     - any material, uncured breach by Mr. Aelvoet of his employment agreement.

     The completion of the WORLDxCHANGE merger would constitute a change of
control of WORLDxCHANGE under Mr. Aelvoet's employment agreement.

     Pursuant to three separate stock option agreements with WORLDxCHANGE, Mr.
Aelvoet has options to purchase 50,000 WORLDxCHANGE shares at $9.00 per share,
25,000 shares at $10.00 per share, and 75,000 shares at $11.00 per share. Of the
options to purchase 50,000 shares, options to purchase 25,000 shares are
currently vested, with the remainder vesting at the rate of 3,125 shares per
quarter commencing on July 1, 2000. Of the options to purchase 25,000 shares,
options to purchase 7,812.5 shares are currently vested, with the remainder
vesting at the rate of 1,562.5 shares per quarter commencing on August 1, 2000.
Of the options to purchase 75,000 shares, options to purchase 14,062.5 shares
are currently vested, with the remainder vesting at the rate of 4,687.5 shares
per quarter commencing on July 1, 2000. Under Mr. Aelvoet's option agreements,
if his employment with WORLDxCHANGE is involuntarily terminated within 12 months
following a change of control of WORLDxCHANGE, his options would become
immediately fully vested and remain exercisable until the earlier of one year
from the date of such termination or ten years from the applicable grant date.
Mr. Aelvoet's stock option agreements define "involuntary termination" as:

     - Mr. Aelvoet's involuntary dismissal or discharge for reasons other than
       misconduct; or

     - Mr. Aelvoet's voluntary resignation following:

      - a material reduction in Mr. Aelvoet's responsibilities;

      - a 15% or greater decrease in Mr. Aelvoet's total compensation; or

      - a relocation of Mr. Aelvoet's place of employment by more than 50 miles
        without Mr. Aelvoet's consent.

     Eric G. Lipoff, WORLDxCHANGE's Vice President and General Counsel, has an
employment agreement with WORLDxCHANGE that provides that, if in connection with
a change of control of WORLDxCHANGE or otherwise, WORLDxCHANGE terminates Mr.
Lipoff's employment without

                                       126
<PAGE>   140

cause or there is otherwise an involuntary termination of Mr. Lipoff's
employment, Mr. Lipoff will be entitled to:

     - the payment of any earned but unpaid salary and/or bonus under the
       agreement; and

     - the amount of compensation that he would have earned under the agreement
       from the date of termination through December 31, 2002 (currently $16,666
       per month) plus the cost for Mr. Lipoff to obtain benefits equivalent to
       those in effect at the time of the termination through December 31, 2002.

Mr. Lipoff's employment agreement defines "cause" to include:

     - willful misconduct of a serious nature in connection with his employment;

     - abandonment of employment or excessive absences after reasonable notice;

     - conflict of interest or breach of fiduciary duty involving his
       responsibilities as an employee involving intent for or obtainment of
       material personal or family profit;

     - conviction of any felony criminal offense; or

     - the issuance by any court or other governmental entity of an order
       prohibiting Mr. Lipoff's continued employment with WORLDxCHANGE which is
       not vacated within ten days after its entry.

     The agreement defines an "involuntary termination" as:

     - the relocation of Mr. Lipoff to a facility or location outside the
       California counties of Orange or San Diego without Mr. Lipoff's consent;

     - the failure of WORLDxCHANGE to have Mr. Lipoff's employment agreement
       assumed by any successor entity; or

     - any circumstances that would constitute a constructive termination of Mr.
       Lipoff's employment under California law.

The completion of the WORLDxCHANGE merger would constitute a change of control
of WORLDxCHANGE under Mr. Lipoff's employment agreement.

     Mr. Lipoff also has an option to purchase a total of 150,000 shares of
WORLDxCHANGE common stock at $10.00 per share. Under the WORLDxCHANGE merger
agreement, all of these options will be converted into the right to acquire
shares of World Access common stock in accordance with the WORLDxCHANGE merger
agreement. Pursuant to Mr. Lipoff's option agreement, this option will fully
vest on December 31, 2002, except that the option will immediately fully vest if
Mr. Lipoff's employment with WORLDxCHANGE is terminated without cause at any
time prior to December 31, 2002. Mr. Lipoff's stock option agreement defines
"cause" as it is defined in his employment agreement. If the vesting of this
option is so accelerated, Mr. Lipoff will have 90 days following the termination
of his employment to exercise the option.

     Effective January 3, 2000, each of Sen. Paul Laxalt and Dann Angeloff, who
are directors of WORLDxCHANGE, received an option to purchase 12,500 shares of
WORLDxCHANGE common stock at $10.00 per share. Under the WORLDxCHANGE merger
agreement, all of these options will, to the extent not exercised by Sen. Laxalt
and Mr. Angeloff, as applicable, as of the effective time of the WORLDxCHANGE
merger, be converted into the right to acquire shares of World Access common
stock in accordance with the WORLDxCHANGE merger agreement. These options are
each currently vested as to 1,041.67 shares and vest at the rate of an
additional 1,041.67 shares per month until fully vested. However, upon a change
of control of WORLDxCHANGE, these options will each immediately fully vest and
remain exercisable until the earlier of one year after the termination of these
directors following a change of control of WORLDxCHANGE or ten years from the
date of grant. The completion of the WORLDxCHANGE merger would constitute a
change of control of WORLDxCHANGE under the terms of the options.

                       THE WORLDXCHANGE MERGER AGREEMENT

     This section of the joint proxy statement/prospectus describes 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 upon the satisfaction of the conditions for such payment
contained in the WORLDxCHANGE merger agreement and to make the necessary
conforming changes. The original WORLDxCHANGE merger agreement, as amended, is
referred to in this joint proxy statement/prospectus as the WORLDxCHANGE merger
agreement. While World Access and WORLDxCHANGE believe that the description
covers the material terms of the WORLDxCHANGE merger agreement, this summary may
not contain all of the information that is important to you. The WORLDxCHANGE
merger agreement is attached to this joint proxy statement/prospectus as Annex
B, and World Access and WORLDxCHANGE urge you to read it carefully.

THE WORLDXCHANGE MERGER/EFFECTIVE TIME

     The WORLDxCHANGE merger agreement provides that upon completion of the
merger, WORLDxCHANGE will be merged with and into WORLDxCHANGE Communications,
Inc. f/k/a CTI Merger Co., a wholly-owned subsidiary of World Access.
WORLDxCHANGE Communications, Inc. f/k/a CTI Merger Co. will survive the merger.
On the closing date 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. Upon the filing of
the certificate of merger and the agreement of merger, the WORLDxCHANGE merger
will be effective.

THE WORLDXCHANGE MERGER CONSIDERATION

     Each share of WORLDxCHANGE capital stock owned or held by WORLDxCHANGE or a
subsidiary of WORLDxCHANGE will no longer be outstanding and will be canceled
and retired, and no consideration will be delivered for such shares.

     Each share of WORLDxCHANGE capital 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.

     Of the shares of World Access common stock to be issued to the WORLDxCHANGE
shareholders in the WORLDxCHANGE merger, 2,453,385 of such shares will be
delivered to SunTrust Bank, Atlanta, as escrow agent. These shares will be held
by SunTrust Bank as security for claims by World Access for indemnification
pursuant to the WORLDxCHANGE merger agreement and the applicable escrow

World Access' exclusive source of recovery for indemnification claims.

     At the closing of the WORLDxCHANGE merger, 49,068 of the shares of World
Access common stock to be issued to the WORLDxCHANGE shareholders will be

or (iii) any purchase or sale of, or tender or exchange offer for, a material
portion of the equity securities of WORLDxCHANGE.

TREATMENT OF WORLDXCHANGE STOCK OPTIONS AND WARRANTS

     Upon completion of the WORLDxCHANGE merger, each outstanding option or
warrant to purchase WORLDxCHANGE capital stock 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 WORLDxCHANGE common stock covered under such
WORLDxCHANGE stock option or warrant multiplied by 0.6583 at a per share price
equal to the exercise price specified in the WORLDxCHANGE option or warrant
divided

                                       131
<PAGE>   145

       of World Access common stock pursuant to the WORLDxCHANGE merger
       agreement; and

     - no law, order or injunction must be adopted or issued which has the
       effect of making the WORLDxCHANGE merger illegal or prohibiting

       WORLDxCHANGE operates and not specifically relating to WORLDxCHANGE;

     - all consents and approvals required of WORLDxCHANGE to complete the
       WORLDxCHANGE merger must be obtained, except where the failure to obtain
       any such consent or approval would not have a Material Adverse Effect on
       World Access or the surviving corporation;

     - WORLDxCHANGE's legal counsel must have delivered to World Access a legal
       opinion pertaining to the corporate existence of WORLDxCHANGE, the
       corporate power and authority of WORLDxCHANGE to execute and perform the
       WORLDxCHANGE merger agreement, and the effectiveness of the WORLDxCHANGE

     A "Material Adverse Effect" is any change, circumstance or effect or breach
of any of the provisions of the WORLDxCHANGE merger agreement that individually,
or in the aggregate, is or would reasonably be expected to be materially adverse
to the business, financial condition or results of operations of an entity taken
as a whole with its subsidiaries or the ability of such entity to complete the
transactions contemplated by the WORLDxCHANGE merger agreement.

TERMINATION OF THE WORLDXCHANGE MERGER AGREEMENT

     The WORLDxCHANGE merger agreement may be terminated at any time prior to
completion of the WORLDxCHANGE merger:

     - by mutual written consent of World Access and WORLDxCHANGE;

     - by World Access or WORLDxCHANGE, if the other party fails to comply in
       any material respects with any of its covenants or agreements in the
       WORLDxCHANGE merger agreement, which failure to comply is not cured
       within 30 days following receipt of notice of breach. However, if a
       breach is curable through the use of reasonable efforts, the
       non-breaching party may not terminate the WORLDxCHANGE merger agreement
       so long as the breaching party is using reasonable efforts to cure the
       breach. Further, no party may terminate the WORLDxCHANGE merger agreement
       if such party is then failing to comply in any material respect with any
       of its covenants and agreements;

     - by World Access or WORLDxCHANGE, if the other party has breached any of
       its representations or warranties, which breach has not been cured within
       30 days following receipt of written notice of the breach. However, if
       the breach is curable through the use of reasonable efforts, the non-
       breaching party may not terminate the WORLDxCHANGE merger agreement so
       long as the breaching party is using reasonable efforts to cure the
       breach. Further, no party may terminate the WORLDxCHANGE merger agreement
       unless the breach would have a Material Adverse Effect on World Access,
       the surviving corporation in the WORLDxCHANGE merger or World Access and
       such surviving corporation;

     - by World Access or WORLDxCHANGE, if the WORLDxCHANGE merger is not
       completed before October 31, 2000 except that the right to terminate the
       WORLDxCHANGE merger agreement is not available to any 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 October 31, 2000 and such
       action or failure to act constitutes a breach of the WORLDxCHANGE merger
       agreement;

     - by World Access or WORLDxCHANGE if any governmental entity has issued a
       final and nonappealable order, decree or ruling permanently enjoining or
       prohibiting the WORLDxCHANGE merger or has failed to issue an order,
       decree or ruling (which failure to issue is final and nonappealable),
       which, in either case, is necessary to fulfill a party's obligation to
       complete the WORLDxCHANGE merger. However, no party may terminate the
       WORLDxCHANGE merger agreement if such party's failure to fulfill any
       obligation under the WORLDxCHANGE merger agreement is the cause of such
       action or inaction by the governmental entity; or

     - by World Access or WORLDxCHANGE, if the WORLDxCHANGE merger agreement
       fails to receive the requisite vote for adoption 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 (whether
before or after adoption of the WORLDxCHANGE merger agreement by the
stockholders of World Access and WORLDxCHANGE). However, following stockholder
approval, no amendment may be made which, by law or in accordance with rules of
any relevant stock exchange or automatic quotations system, requires

                                       134
<PAGE>   148

further approval by the stockholders. World Access and WORLDxCHANGE may, at any
time prior to completion of the WORLDxCHANGE merger, 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 (the "WAXS Protected Parties") as a result of
any of the following:

     - a breach of any representation or warranty of WORLDxCHANGE in the
       WORLDxCHANGE merger agreement (except with respect to certain tax matters
       and, except in limited circumstances, without regard to materiality
       qualifications contained in such representation or warranty);

     - 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 as set forth in the WORLDxCHANGE merger
       agreement (without regard, except in limited circumstances, to any
       materiality qualification contained in such representation or warranty);

     - 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
       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.

     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 the WAXS Protected
Parties may claim indemnification for the amount of losses (in each case net of
$150,000) in excess of $3.0 million. The sole remedy of any WAXS Protected Party
for a breach of a representation or warranty of WORLDxCHANGE is the right to
receive indemnification pursuant to the WORLDxCHANGE merger agreement, and the
shares of World Access common stock to be held in escrow will constitute the
sole source of recovery for the WAXS Protected Parties.

     Upon approval of the WORLDxCHANGE merger agreement and the transactions
contemplated thereby 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 and all actions and make
any and all decisions required or permitted to be taken or made by the
WORLDxCHANGE shareholders under the WORLDxCHANGE merger agreement and the escrow
agreement (including those related to indemnification).

                         RELATED TRANSACTION 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, W. Tod Chmar 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 (i) the termination of the WORLDxCHANGE
merger agreement in accordance with the termination provisions of the
WORLDxCHANGE merger agreement, (ii) the completion of the WORLDxCHANGE merger
and (iii) 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, beneficially or of record, shares of World Access capital stock
representing approximately      % of the voting stock of World Access voting
together as a single class. A copy of the voting and stock transfer restriction
agreement is attached as Annex J to this joint proxy statement/prospectus.

WORLDXCHANGE VOTING AGREEMENTS

     World Access has entered into separate voting and stock transfer
restriction agreements with the following WORLDxCHANGE shareholders: Atocha,
L.P.; Roger B. Abbott and Rosalind Abbott, whose shares of WORLDxCHANGE capital
stock are owned jointly; Gold & Appel Transfer S.A.; 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 (i) sell, hypothecate,
       transfer, pledge, encumber, assign or otherwise dispose of (collectively,
       "Transfer"), or enter into any contract or understanding with respect to
       the Transfer of, any shares of WORLDxCHANGE capital stock or options to
       acquire shares, (ii) trade or take any position, hedge or otherwise, with
       respect to shares of WORLDxCHANGE capital stock or options to acquire
       such shares, (iii) enter into any voting arrangement with respect to
       shares of WORLDxCHANGE capital stock or options to acquire such shares or
       (iv) take any action that would make any of such WORLDxCHANGE
       shareholder's representations or warranties untrue to

                                       136
<PAGE>   150

       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 or (ii) the
       expiration of the post-closing stock transfer restrictions set forth in
       the voting and stock transfer restriction agreements.

     While the voting and stock transfer restriction agreements are
substantially similar, they do contain some differences. Edward S. Soren is
permitted to Transfer up to 750,000 shares of World Access common stock issued
to him in the WORLDxCHANGE merger. In addition, Roger B. Abbott and Rosalind
Abbott will be permitted to sell, in the aggregate, shares of World Access
common stock issued to them in the WORLDxCHANGE merger having aggregate gross
cash proceeds of up to $30.0 million.

     As of the WORLDxCHANGE record date, these WORLDxCHANGE shareholders own,
beneficially or of record, shares of WORLDxCHANGE capital stock representing
approximately      % of the voting stock of WORLDxCHANGE on a fully-diluted
basis.

ESCROW AGREEMENT

     As a condition to each party's obligations to complete the WORLDxCHANGE
merger, World Access and WORLDxCHANGE must enter into an escrow agreement to
secure the indemnification obligations of WORLDxCHANGE under the WORLDxCHANGE
merger agreement.

     The escrow agreement contemplates that 2,453,385 shares of World Access
common stock will be delivered to the escrow agent upon completion of the
WORLDxCHANGE merger.

     The escrow agreement provides a mechanism for the release to World Access
of World Access common stock in the event of undisputed claims by World Access
of an indemnifiable loss. If a claim by World Access of a loss is disputed, no
shares may be released by the escrow agent except as directed by a final,
nonappealable decision of a court of competent jurisdiction or a notice in
writing signed by World Access and the WORLDxCHANGE shareholder representative.

     On the first anniversary of the completion of the WORLDxCHANGE merger, the
escrow agent must release to the WORLDxCHANGE shareholders their pro rata
portion of the remaining shares of World Access common stock held in escrow, if
no notice of an indemnifiable loss by World Access is pending at such time. If
one or more notices of loss are pending at such time, the escrow agent will
retain in escrow such number of shares as is sufficient to satisfy the amount
claimed in such notice or notices of loss. The escrow agent will release to the
WORLDxCHANGE shareholders all shares remaining in escrow upon final resolution
of all claims for indemnity.

     For purposes of determining the number of shares of World Access common
stock to be released from, or retained in, escrow, each share will be valued at
$20.38.

     The escrow agreement will terminate on the first to occur of (i) the later
of (a) ten days after the first anniversary of the completion of the
WORLDxCHANGE merger, (b) the satisfaction of all indemnification claims pending
on the first anniversary of the completion of the WORLDxCHANGE merger and (c)
the disbursement of the entire escrow fund in accordance with the escrow
agreement or (ii) a mutual consent signed by World Access and the WORLDxCHANGE
shareholder representative.

WORLD ACCESS -- WORLDXCHANGE SERVICES AGREEMENT

     On February 14, 2000, World Access and WORLDxCHANGE entered into a services
agreement, pursuant to which each party may provide the other party with
operations services pending the completion of the WORLDxCHANGE merger. The World
Access -- WORLDxCHANGE services agreement terminates at the earlier of (i) 90
days following the termination of the WORLDxCHANGE merger agreement or such
earlier time as agreed by the parties, (ii) a written agreement of the parties
terminating the services agreement or (iii) the completion of the WORLDxCHANGE
merger.

FOOTHILL CAPITAL CORPORATION PARTICIPATION AGREEMENT

     On February 11, 2000, World Access entered into a participation agreement
with Foothill Capital Corporation, which, as amended, provides for World Access
to provide up to $45.0 million to be advanced by Foothill to WORLDxCHANGE and
certain of its subsidiaries, including WORLDxCHANGE Communications, Inc., CTS
Telecom Holdings, Inc. and CTS Telecom, Inc. pursuant to the terms of an
existing credit facility evidenced by a Loan and Security Agreement dated as of
March 11, 1997, as thereafter amended, between Foothill, WORLDxCHANGE and the
subsidiaries. The Foothill loan to WORLDxCHANGE and its subsidiaries is
structured as a term loan which bears interest at a rate of 11% per annum,
payable monthly in arrears, and matures on February 11, 2001, subject to
extension by World Access up to October 1, 2003. Both the term loan and the
existing indebtedness to Foothill under the credit facility will be secured by a
blanket security interest in all personal property of WORLDxCHANGE and the
subsidiaries. The participation interest of World Access in the term loan is a
last-out participation, such that at any time after an acceleration by Foothill
of the maturity of the obligations under the credit facility, or the failure of
WORLDxCHANGE and the subsidiaries to repay such obligations in full upon their
stated maturity, all amounts collected or received by Foothill from collateral
liquidation or otherwise will be applied first to repayment of all principal,
interest and costs owing to Foothill, and thereafter, to repayment of amounts
owing to World Access.

                    COMPARATIVE PER SHARE MARKET PRICE DATA

     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.

</TABLE>

     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) May 23, 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 .3905, 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

          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 three different
scenarios, that World Access has completed or are currently contemplated. The
first scenario assumes World Access acquires both STAR and WORLDxCHANGE. The
second scenario assumes World Access acquires STAR but not WORLDxCHANGE. The
third scenario assumes World Access acquires WORLDxCHANGE but not STAR. 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 CommNet 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 three scenarios gives effect to the STAR and WORLDxCHANGE 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 three scenarios also give effect to the LDI acquisitions as if
the acquisition had occurred on January 1, 2000.

     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 and
WORLDxCHANGE 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 $150.0 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

</TABLE>

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

            (a) The average market price represents the average market price of
                World Access Common Stock for the three trading days prior and
                the three trading days subsequent to February 14, 2000, the date
                economic terms of the merger were announced.

        (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. Any
             intrinsic value that is allocated to unearned compensation is
             deducted from the fair value of the unvested options.

             In accordance with the merger agreement, each STAR option is to be
             converted into an option to purchase 0.3905 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
             692,766 and 758,982 World Access options, respectively, totaling
             1,451,748.

             The fair value of the 692,766 vested options is $9.9 million
             computed using the Black-Scholes Option Pricing Model and is
             included in the purchase price. The fair value of the 758,982
             unvested options is $9.3 million computed using the Black-Scholes
             Option Pricing Model. Of this amount, $2.9 million was allocated to
             unearned compensation and $6.4

            million is included in the purchase price. 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 $150.0 million.

     (4)  The issuance of World Access unvested options in exchange for STAR
          unvested options resulted in unearned compensation of $2.9 million
          which will be recognized as compensation cost over the remaining
          future vesting period of the unvested options. The weighted average
          remaining vesting period for the unvested options is 43 months,
          resulting in compensation cost of $798,000 for the year ended December
          31, 1999 and $200,000 for the three months ended March 31, 2000.

     (5)  Elimination of STAR's historical goodwill and other intangibles.

     (6)  Elimination of STAR's pro forma stockholders equity accounts.

     (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 22,894,000
          shares of common stock to complete the STAR merger. 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.

     (11) The WORLDxCHANGE merger will be accounted for under the purchase
          method of accounting. The total cost to acquire WORLDxCHANGE is
          subject to change, to the extent that the number of shares of
          WORLDxCHANGE 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 the liabilities assumed. The impact of such
          changes could be material. The preliminary purchase price and goodwill

</TABLE>

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

            (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. Any
             intrinsic value that is allocated to unearned compensation is
             deducted from the fair value of the unvested options.

             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. Of this amount,
             $23,000 was allocated to unearned compensation and $5.0 million is
             included in the purchase price. 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) World Access has issued WORLDxCHANGE a $45 million revolving
             credit facility. For purposes of the unaudited pro forma
             information, we have assumed that World Access will provide
             WORLDxCHANGE with $45 million of funding before the merger is
             consummated. As of March 31, 2000, $25 million had been advanced
             to WORLDxCHANGE.

        (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.

</TABLE>

     (13) The issuance of World Access unvested options in exchange for
          WORLDxCHANGE unvested options resulted in unearned compensation of
          $23,000 which will be recognized as compensation cost over the
          remaining future vesting period of the unvested options. The weighted
          average remaining vesting period for the unvested options is 10
          months, resulting in compensation cost of $23,000 for the year ended
          December 31, 1999 and $7,000 for the three months ended March 31,
          2000.

     (14) Elimination of WORLDxCHANGE's historical goodwill and other
          intangibles.

     (15) Elimination of WORLDxCHANGE's historical shareholders' deficit
          accounts.

     (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
          29,824,610 shares issued to complete the WORLDxCHANGE merger. 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.

PRO FORMA WORLD ACCESS

     (20) 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 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%

        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.

     K. 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 LDI's and FaciliCom's net 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
        for the full period.

        stock and warrant redemption accretion.

     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.

                       COMPARISON OF RIGHTS OF HOLDERS OF
                         WORLD ACCESS COMMON STOCK AND
                               STAR COMMON STOCK

     This section of the joint proxy statement/prospectus describes certain
differences between STAR common stock and World Access common stock. While World
Access and STAR believe that the description covers the material differences
between the two, this summary may not contain all of the information that is
important to STAR stockholders, including the information set forth in the
certificates of incorporation and bylaws of each company. STAR stockholders
should read this entire document and the other documents referred to carefully
for a more complete understanding of the differences between STAR common stock
and World Access common stock.

     The rights of stockholders of STAR are currently governed by STAR's
certificate of incorporation, as amended and restated, and STAR's bylaws. After
the completion of the STAR merger, STAR stockholders will become stockholders of
World Access. The rights of stockholders of World Access are governed by World
Access' certificate of incorporation, as amended, and World Access' bylaws.
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 the General Corporation Law of the State of Delaware. The following
paragraphs compare certain 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 STAR consists of 100,000,000 shares of
common stock, of which shares were outstanding as of May 22, 2000 and 5,000,000
shares of preferred stock, of which no shares were outstanding as of May 22,
2000.

     The authorized capital stock of World Access currently consists of
160,000,000 shares, of which 150,000,000 shares shall be common stock of $.01
par value per share, and 10,000,000 shares of which shall be 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 May 22, 2000, 60,101,658 shares of World Access
common stock were outstanding and 584,260 shares of World Access preferred stock
were outstanding.

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.

SPECIAL MEETING OF STOCKHOLDERS

     Special meetings of World Access may be called by a majority of 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 the majority of
the board of directors.

ACTION BY WRITTEN CONSENT IN LIEU OF A STOCKHOLDERS' MEETING

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

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

                                       164
<PAGE>   178

VOTING BY WRITTEN BALLOT

     World Access' bylaws and STAR's certificate of incorporation both provide
that the election of directors need not be by written ballot.

RECORD DATE FOR DETERMINING STOCKHOLDERS

     Both the World Access bylaws and the STAR bylaws provide that their
respective 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, shall not be more
       than 60 days nor less than ten days before the date of the meeting; and

     - in the case of any other action, shall not be more than 60 days prior 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 shall be at the close of business on
       the day next preceding the day on which notice is given, or, if notice is
       waived, at the close of business on the day next preceding the day on
       which the meeting is held; and

     - the record date for determining stockholders for any other purpose shall
       be at the close of business on the same day on which the World Access
       board of directors adopts the related resolution.

NOMINATION OF DIRECTORS

     The STAR certificate of incorporation and bylaws are silent with respect to
the nomination of persons for election to the STAR board of 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 be timely, a stockholder's nomination notice must be received by
World Access at least 120 days prior to the one-year anniversary of the date of
the proxy statement in connection with the previous year's annual meeting of
stockholders. If (i) no annual meeting was held in the previous year, (ii) 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 (iii) the upcoming
meeting is not an annual meeting, 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.

NUMBER OF DIRECTORS

     The World Access amended certificate of incorporation and bylaws provide
that the World Access board of directors must consist of not fewer than three
and not more than 12 directors, with the exact number to be fixed 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 the certificate of incorporation which would
increase the maximum number of directors to 15.

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

                                       165
<PAGE>   179

CLASSIFIED BOARD OF DIRECTORS

     Delaware law provides that a corporation's board of directors may be
divided into various classes with staggered terms of office. Each of World
Access' and STAR's board of directors is divided into three classes, as nearly
equal in size as possible, with one class being elected annually. Directors of
STAR and World Access are elected to a term of three years 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 an amendment to the certificate of incorporation of World Access which would
eliminate World Access' classified board of directors. If this amendment is
approved by the requisite vote of the World Access stockholders, all World
Access 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 by World Access stockholders would be elected as the directors.

REMOVAL OF DIRECTORS

     Delaware law provides that any director or the entire board of directors of
STAR may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election 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,
voting together as a single class.

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.

NOTICE OF SPECIAL MEETING 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.

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.

     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.

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, and 184,000 shares designated as
Series D preferred stock are issued and outstanding. The material terms of the
Series A preferred stock, the Series C preferred stock and the Series D
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.

     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
                                       167
<PAGE>   181

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.

     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

                                       168
<PAGE>   182

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 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
                                       169
<PAGE>   183

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.

with a network of owned and leased undersea and land-based fiber optic cables.

     WORLDxCHANGE's services currently include international and domestic long
distance telephone service, pre-paid calling card services, operator services,
Internet access and e-commerce services. WORLDxCHANGE markets these services

WORLDxCHANGE currently serves customers in the United States, Australia,
Belgium, Canada, France, Germany, Guatemala, The Netherlands, New Zealand and
the United Kingdom.

SERVICES

     WORLDxCHANGE provides a variety of retail telecommunication and information
services to residential and commercial customers, including international and
domestic long distance telephone service and pre-paid calling card services,
operator services, Internet access and e-commerce services. WORLDxCHANGE also
provides wholesale and resale services to carrier customers.

  Retail services

     WORLDxCHANGE offers international and domestic long distance telephone
service and pre-paid calling card services in all of its primary geographic
markets, including the United States, Australia, Belgium, Canada, France,
Germany, The Netherlands, New Zealand and the United Kingdom. In addition,
WORLDxCHANGE offers e-commerce services in the United States and Canada, as well
as 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,
Australia and New Zealand, customers who have pre-subscribed to WORLDxCHANGE's
service may access the WORLDxCHANGE network by dialing a prefix. U.S. customers
who have pre-subscribed to WORLDxCHANGE's service may use the service by dialing
"1+," and U.S. customers who have not pre-subscribed must dial a seven-digit
code. Most of WORLDxCHANGE's U.S. residential customers use the seven-digit
access code. WORLDxCHANGE's international and domestic long distance telephone
service generally enables customers to call to any destination.

     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 retail customers for a fixed monthly price.

     e-Commerce services.  WORLDxCHANGE has implemented several e-commerce
services. For example, in July 1999, WORLDxCHANGE introduced "Virtual PIN," a
program under which North American customers are able to purchase and recharge
prepaid calling cards exclusively through the WORLDxCHANGE website, which may be
accessed at www.worldxchange.com. In addition, North American customers are also
offered the "iPlan" billing option, under which they can receive a discount by
having their bills rendered over the Internet instead of by paper invoice. Other
features allow North American customers, via the Internet, to sign up for
WORLDxCHANGE services and make changes to

                                       173
<PAGE>   187

the services they select, view their call data, generate customized billing
reports, and make billing and service inquiries.

     WORLDxCHANGE's e-commerce strategy also includes the "xPectations ML"
marketing program. Under this program, independent representatives can obtain
their own website, which WORLDxCHANGE hosts. This allows the representatives to
use a professionally-designed website to market WORLDxCHANGE's services to
potential customers and the xPectations ML program to prospective new
representatives while allowing WORLDxCHANGE to retain control over the
advertising content on the site.

     Other retail services.  WORLDxCHANGE also provides the other retail
services described below. These services currently account for a relatively
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
       as "follow me" service, under which toll-free calls are automatically
       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
       a day.

     - 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;

     - IRUs in more than 25 million DS-0 miles of on-land fiber optic cable

     WORLDxCHANGE also has arrangements to connect with the telecommunications
networks of dominant 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
local exchange 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 direct interconnection 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
interconnecting with the dominant national carriers. In addition, these
interconnections 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, IRUs in 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 undersea
cables and/or IRUs that connect network cities with substantial calling traffic
between them. However, WORLDxCHANGE has used leased lines in regions where IRUs
are either too expensive or if WORLDxCHANGE believes IRU prices will decline, or
where IRUs are not available. In some cases, WORLDxCHANGE uses compression or
multiplexing equipment to further increase the capacity of its IRUs.

                                       175
<PAGE>   189

     Other.  In addition to the cost of origination, transmission and
termination, the other costs of the WORLDxCHANGE network relate primarily to
switching equipment, compression equipment, WORLDxCHANGE's Internet protocol
overlay and facility/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 infrastructure.
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 effecting least-cost routing. WORLDxCHANGE has installed a wide area
network linking all its switch sites, which coordinates the use of
WORLDxCHANGE's systems.

     TCIB 2000 feature platform.  The TCIB 2000 performs switching, billing and
customer care functions. These services are integrated with other platforms like
the Siemens EWSD or Ericsson AXE-10 switch. The TCIB 2000 system is used in the
operation of WORLDxCHANGE's operating subsidiaries in Belgium, Guatemala, The
Netherlands and New Zealand.

  North American network

     WORLDxCHANGE has switches in each of the ten cities listed below that are
connected with a fiber optic backbone. WORLDxCHANGE expects to relocate its
switch in Seattle to San Francisco by approximately July 1, 2000.

<TABLE>

</TABLE>

     WORLDxCHANGE connects the North American portion of its network with other
regions of the world through direct ownership interests or IRUs 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 approximately 17.5
million route miles of fiber optic transmission capacity, representing most of
its U.S. transmission capacity, from MCI WorldCom. As those leases expired, they
were converted to long-term IRU arrangements covering the same capacity. The IRU
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 covering approximately 19.4 million route miles of fiber optic
transmission capacity. This lease is convertible into a 15-year IRU on the same
capacity at the end of the lease.

  European network

     WORLDxCHANGE uses two TCIB 2000 switches in continental Europe, and
Ericsson AXE-10 switches in the United Kingdom and Germany. WORLDxCHANGE
connects the European portion of its network with other regions of the world
through direct ownership interests or IRUs 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.

                                       176
<PAGE>   190

     ACC Acquisition.  In November 1999, WORLDxCHANGE acquired the operations of
ACC Corp. in France, Germany and the United Kingdom, and a switch in Italy.
WORLDxCHANGE is in the process of integrating the operations and network
equipment and capacity 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 five TCIB 2000 switches in Australia, as well
as Siemens EWSD switches in Sydney, Melbourne, Perth and Brisbane in Australia.
WORLDxCHANGE is interconnected with Telstra through Telstra's National Access
interconnection program. WORLDxCHANGE connects the Asia Pacific portion of its
network with other regions of the world through direct ownership interests or
IRUs 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 TCIB 2000 switch in Guatemala City, Guatemala and
Santiago, Chile. WORLDxCHANGE connects the Latin American portion of its network
through a direct ownership interest in the Pan American undersea cable, as well
as via satellite services.

  Network hardware and software

     North America.  WORLDxCHANGE uses Siemens DC0-CS and EWSD switches
throughout its North American network. These switches enable WORLDxCHANGE to
handle large, simultaneous call volumes, provide high quality service to
customers and seamlessly interconnect with local operators.

     WORLDxCHANGE has installed the Siemens EWSD switch at its Dallas, Los
Angeles and New York switch sites. The Siemens EWSD switch in Dallas has 15,000
ports, the Los Angeles switch has 21,000 ports, and the EWSD switch in New York
has 31,000 ports. The Siemens DC0-CS switch has approximately 5,760 ports. A
Siemens EWSD switch with 21,000 ports can simultaneously handle 21,000 calls.
WORLDxCHANGE may replace the DC0-CS switches as capacity limits on those
switches are approached.

     During the fourth quarter of 1998, WORLDxCHANGE experienced technical
problems with the new Siemens EWSD 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 Siemens to fix the problems and has
implemented new procedures to detect any similar problems that may arise with
the Siemens EWSD switches in the future. Siemens has agreed to provide
WORLDxCHANGE with additional future lease financing for third-party equipment,
free software and deferred lease payments on most of the EWSD and DC0-CS
switches in the United States. There can be no assurance that WORLDxCHANGE will
not experience additional problems with the EWSD or other switching equipment in
the future.

     Overseas operations.  WORLDxCHANGE uses a combination of TCIB 2000, Siemens
EWSD and Ericsson AXE-10 switching equipment in certain markets outside of North
America. The TCIB 2000 is a personal computer-based, integrated telephony
hardware and software platform designed by WORLDxCHANGE that combines standard
switching functions with customer care 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 platform in place of the faulty ACC system in the United Kingdom.
However, there can be no assurance that this replacement billing platform will
not also experience problems.

     Least cost routing.  WORLDxCHANGE uses a combination of network 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 change.

                                       177
<PAGE>   191

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 Ascend Communications MAX/TNT random access server in Los
Angeles. The modems interface with a Radius server in Los Angeles. The Radius
server verifies the customer's account number and password. Once the Radius
server verifies the customer's account information, the call goes to a Cisco
Series 7206 router for connection to the Internet backbone. WORLDxCHANGE uses
Navais software to monitor the integrity of 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's correspondent
relationships or through the third party itself. 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 of that carrier's network. The carrier
would then terminate the call in Afghanistan either through a correspondent
relationship that it has with a carrier with facilities in Afghanistan or
directly through its own local facilities.

     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 FCC 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 FCC 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.

                                       178
<PAGE>   192

     Direct mail.  WORLDxCHANGE has developed a number of different direct mail
programs, each tailored 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.

     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 several e-commerce services, such
as the "Virtual PIN" program under which our 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
distilled from 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,

                                       179
<PAGE>   193

independent agents also market WORLDxCHANGE's long distance services to Belgian
commercial customers.

     WORLDxCHANGE is in the process of establishing a sales and marketing
infrastructure 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
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. These foreign operating subsidiaries are briefly discussed below.

  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.

                                       180

  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 December 31, 1999, WORLDxCHANGE employed approximately 1,312 people,
including officers, administrative and sales personnel.

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 (the "CPUC") issued
an order revoking WORLDxCHANGE's authority to provide intrastate calling service
in California and imposing certain

                                       181
<PAGE>   195

other fines and penalties, including, among other things, a $19.6 million fine,
against WORLDxCHANGE based on the CPUC'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 CPUC directives. Under the CPUC's order, the sanctions and fines are
binding on any successor to WORLDxCHANGE, unless the CPUC orders otherwise.
WORLDxCHANGE has implemented a number of policies and procedures designed to
help reduce the likelihood of future allegations of the kind leading to the
CPUC'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
CPUC directives, WORLDxCHANGE would be subject to paying the $17.6 million
portion of the CPUC 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 CPUC 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 CPUC 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. In addition to historical
information, the following discussion and other parts of this prospectus contain
forward-looking information that involves risks and uncertainties.
WORLDxCHANGE's actual results could differ materially from those anticipated by
forward-looking information due to factors discussed under "Business" and
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 and non-recurring fees that are 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.

</TABLE>

     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, known as "MIUs," and long-term rights of use in cables or other
facilities, known as "IRUs," 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 MIUs or IRUs reduces its utilization of leased
lines and the facilities of other long distance carriers, WORLDxCHANGE believes
the increase in depreciation expense associated with the MIUs or IRUs 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

                                       184
<PAGE>   198

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

     - MIU or IRU 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.

     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
to present fairly the unaudited quarterly results of operations data. The
pro-forma adjustments give effect to the amortization of the intangible assets
recorded in association with the ACC Europe purchase and the recognition of
interest expense on the debt incurred as if the purchase were incurred at the
beginning of the periods presented. The supplemental unaudited pro-forma
quarterly statements of operations is not necessarily indicative of

                                       185

either future results of operations or results that might have been achieved if
the purchase had been consummated as of the indicated dates.

</TABLE>

     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.

                                       186
<PAGE>   200

     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

                                       187
<PAGE>   201

revenues. Cost of 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. 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 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.

                                       188
<PAGE>   202

     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.

     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.

  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

                                       189
<PAGE>   203

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 due to efficiencies gained as
WORLDxCHANGE's revenues increased.

     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
                                       190
<PAGE>   204

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 CPUC subject to
WORLDxCHANGE's refraining from committing any violations of statutes or CPUC
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.

     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
                                       191
<PAGE>   205

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 or AIF. 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 AIF 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, 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

                                       192
<PAGE>   206

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 capacity on 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 indefeasible 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.

     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 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 under the loan 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.

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. The remaining $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.
                                       193
<PAGE>   207

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 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

                                       194
<PAGE>   208

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.

     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.

            COMPARISON OF THE RIGHTS OF SHAREHOLDERS OF WORLDXCHANGE
                        AND STOCKHOLDERS OF WORLD ACCESS

     The rights of WORLDxCHANGE's shareholders are governed by its articles of
incorporation, as amended and restated, its bylaws, as amended and restated, and
the laws of the State of California. 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. Upon completion of the WORLDxCHANGE merger, the
WORLDxCHANGE shareholders will become World Access stockholders, and their
rights will be governed by World Access' certificate of incorporation, as
amended, its bylaws and the laws of the State of Delaware.

     The following is a summary of the material differences between the rights
of holders of WORLDxCHANGE capital stock and the rights of holders of World
Access capital stock at the date hereof. These differences arise from
differences between the Delaware General Corporation Law, or DGCL, and the
California General Corporation Law, or CGCL, and between the respective
corporate charters and bylaws of WORLDxCHANGE and World Access. This summary is
not a complete comparison of rights that may be of interest to you; therefore,
you should read the full text of each state's corporate statute and the
respective corporate charters and bylaws of WORLDxCHANGE and World Access. For
information on how to obtain these documents, see "WHERE YOU CAN FIND MORE
INFORMATION" on page                .

     Pursuant to the Voting and Share Transfer Restriction Agreements referred
to on page 136, 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 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 March 22, 2000, 37,022,683 shares of WORLDxCHANGE common stock were
outstanding, and 80,000 shares of WORLDxCHANGE preferred stock were outstanding.

     The authorized capital stock of World Access consists of 160,000,000
shares, of which 150,000,000 shares shall be common stock of $.01 par value per
share, and 10,000,000 shares of which shall be 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                ,        shares of World Access
common stock were outstanding, and        shares of World Access preferred stock
were outstanding.

COMPARISON OF RIGHTS OF COMMON STOCK

     The holders of WORLDxCHANGE common stock are entitled to one vote per
share. The holders of WORLDxCHANGE common stock are entitled to receive
dividends when and as declared by the board of directors out of funds legally
available for the payment of dividends. The holders of WORLDxCHANGE common stock
have no preemptive rights or redemption rights.

     The holders of World Access common stock are entitled to one vote per
share. The holders of common stock are entitled to receive such dividends as may
be declared from time to time by the board of directors. The holders of World
Access common stock have no preemptive rights or redemption rights.

COMPARISON OF SHAREHOLDER RIGHTS UNDER DELAWARE AND CALIFORNIA LAW

     Number of directors.  World Access' bylaws provide for a board of directors
of not less than three nor more than 12, with the exact number to be fixed 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 the certificate of incorporation
which would increase the maximum number of directors to 15. World Access' board
currently consists of 11 members. Following the completion of the WORLDxCHANGE
merger, the World Access board of directors will consist of 11 members.

     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 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.

     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.

     Removal of directors.  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.

     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.

     Filling new seats or vacancies on the board of directors.  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.

     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.

                                       199
<PAGE>   213

     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.

     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.

     Indemnification and limitation of liability.  California and Delaware have
similar laws governing indemnification by a corporation of its officers,
directors, employees and other agents. The laws of both states permit, with
certain exceptions, a corporation to adopt charter provisions eliminating the
liability of its directors to the corporation or its shareholders for monetary
damages for breach of the directors' fiduciary duty of care. There are
nonetheless certain differences between the laws of the two states and the
charters of WORLDxCHANGE and World Access with respect to indemnification and
limitation of liability, which are summarized below.

     WORLDxCHANGE's articles of incorporation eliminate the liability of
directors to the corporation to the fullest extent permissible under California
law. California law does not permit the elimination of monetary liability where
such liability is based on: (i) intentional misconduct or knowing and culpable
violation of law; (ii) acts or omissions that a director believes to be contrary
to the best interests of the corporation or its shareholders or that involve the
absence of good faith on the part of the director; (iii) receipt by the director
of an improper personal benefit; (iv) acts or omissions that show reckless
disregard for the director's duty to the corporation or its shareholders, where
the director in the ordinary course of performing a director's duties should be
aware of a risk of serious injury to the corporation or its shareholders; (v)
acts or omissions that constitute an unexcused pattern of inattention that
amounts to an abdication of the director's duty to the corporation and its
shareholders; (vi) transactions between the corporation and a director who has a
material financial interest in such transaction; and (vii) liability for
improper distributions, loans or guarantees.

     World Access' certificate of incorporation eliminates the liability of
directors to World Access or its stockholders for monetary damages for breach of
fiduciary duty as a director to the fullest extent permissible under Delaware
law, as it may be amended and supplemented. Under Delaware law, such provision
may not eliminate or limit a director's monetary liability for: (i) breaches of
the director's duty of loyalty to the corporation or its stockholders; (ii) acts
or omissions not in good faith or involving intentional misconduct or knowing
violations of law; (iii) the payment of unlawful dividends or unlawful stock
repurchases or redemptions; or (iv) transaction in which the director received
an improper personal benefit. Such limitation of liability provisions also may
not limit a director's liability for violation of, or otherwise relieve World
Access or its directors from the necessity of complying with, federal or state
securities laws, or affect the availability of nonmonetary remedies such as
injunctive relief or rescission.

     California and Delaware law require indemnification of a present or former
director or officer of the corporation when the individual has defended
successfully any action on the merits. Delaware law generally permits
indemnification of expenses, including attorneys' fees, actually and reasonably
incurred in the defense or settlement of a derivative or third-party action,
provided there is a determination by a majority vote of a disinterested quorum
of the directors, by independent legal counsel or by a majority vote of a quorum
of the stockholders that the person seeking indemnification acted in good faith
and in a manner reasonably believed to be in the best interests of the
corporation. California law generally permits the same. Under Delaware law, no
indemnification may be made in respect of any derivative action or action in
which the individual has been adjudged to be liable to the corporation, unless
the court so authorizes. Under California law, no indemnification may be made
(i) in respect of any derivative action or action in which the individual has
been adjudged liable to the corporation, unless the court so authorizes, (ii) of
amounts paid in settling or otherwise disposing of a pending action without
court approval, or (iii) of

                                       200
<PAGE>   214

expenses incurred in defending a pending action which is settled or otherwise
disposed of without court approval.

     Expenses incurred by an officer or director in defending an action may be
paid in advance, under Delaware law and California law, if such director or
officer undertakes to repay such amounts if it is ultimately determined that he
or she is not entitled to indemnification. In addition, the laws of both states
authorize a corporation's purchase of indemnity insurance for the benefit of its
officers, directors, employees and agents whether or not the corporation would
have the power to indemnify against the liability covered by the policy.
WORLDxCHANGE's bylaws authorize the purchase of such insurance.

     California law permits a California corporation to provide rights to
indemnification beyond those provided therein to the extent such additional
indemnification is authorized in the corporation's articles of incorporation.
Thus, if so authorized, rights to indemnification may be provided pursuant to
agreements or bylaw provisions which make mandatory the permissive
indemnification provided by California law. In addition, Delaware law states
that the indemnification provided by statute shall not be deemed exclusive of
any other rights under any bylaw, agreement, vote of shareholders, or of
disinterested directors, or otherwise.

     Interested director transactions.  Under both California and Delaware law,
certain contracts or transactions in which one or more of a corporation's
directors have an interest are not void or voidable because of such interest if
certain conditions are met. With certain exceptions, the conditions are similar
under California and Delaware law. Under California and Delaware law, (i) either
the shareholders or the board of directors must approve any such contract or
transaction after full disclosure of the material facts, and, in the case of
board approval, the contract or transaction must also be "just and reasonable"
(in California) or "fair" (in Delaware) to the corporation, or (ii) the contract
or transaction must have been "just and reasonable" or "fair" (as applicable) as
to the corporation at the time it was approved. In the latter case, California
law explicitly places the burden of proof on the interested director. Under
California law, if shareholder approval is sought, the interested director is
not entitled to vote his shares at a shareholder meeting with respect to any
action regarding such contract or transaction. If board approval is sought, the
contract or transaction must be approved by a majority vote of a quorum of the
directors, without counting the vote of any interested directors (except that
interested directors may be counted for purposes of establishing a quorum).
Under Delaware law, if stockholder approval is sought generally, the contract or
transaction must be approved in good faith by a majority of stockholders. If
board approval is sought, the contract or transaction must be approved by a
majority of the disinterested directors (even though less than a majority of a
quorum). Therefore, certain transactions that the WORLDxCHANGE board of
directors might not be able to approve because of the number of interested
directors could, in the case of World Access, be approved by a majority of the
disinterested directors of World Access, although less than a majority of a
quorum.

     Loans to officers and employees.  Under California law, a corporation
cannot make any loan or guaranty to or for the benefit of a director or officer
of the corporation or its parent unless such loan or guaranty, or a plan
providing for such loan or guaranty, is approved by shareholders owning a
majority of the outstanding shares of the corporation. However, under California
law, any corporation with 100 or more shareholders of record may seek approval,
by vote of the majority of outstanding shares, of a bylaw provision authorizing
the board of directors alone to approve loans or guaranties to or on behalf of
officers (whether or not such officers are directors) if the board determines
that any such loan or guaranty may reasonably be expected to benefit the
corporation. WORLDxCHANGE's bylaws do not authorize the WORLDxCHANGE board of
directors to approve such loans or guaranties.

     Under Delaware law, a corporation may make loans to, guaranty the
obligations of, or otherwise assist its officers or other employees and those of
its subsidiaries (including directors who are also officers or employees) when
such action, in the judgment of the directors, may reasonably be expected to
benefit the corporation.

     Shareholder derivative suits.  California law provides that a shareholder
bringing a derivative action on behalf of a corporation need not have been a
shareholder at the time of the transaction in question,
                                       201
<PAGE>   215

provided that certain tests are met. Under Delaware law, a stockholder may bring
a derivative action on behalf of the corporation only if the stockholder was a
stockholder of the corporation at the time of the transaction in question or his
or her stock thereafter devolved upon him or her by operation of law. California
law also provides that the corporation or the defendant in a derivative suit may
make a motion to the court for an order requiring the plaintiff shareholder to
furnish a security bond. Delaware does not have a similar bonding requirement.

     Elimination of actions by written consent of shareholders.  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. WORLDxCHANGE's articles of incorporation do not eliminate shareholder
actions by written consent. In contrast, except with respect to actions by
preferred stockholders pursuant to World Access' certificate of incorporation,
World Access stockholder actions may not be taken 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.

     Power to call special meeting of shareholders.  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.

     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.

     Notice procedures.  World Access' bylaws provide that notice of a special
meeting of stockholders must be timely given in writing not less than ten days
nor more than 60 days prior 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 prior to the one-year
anniversary of the date of the proxy statement in connection with the previous
year's annual meeting of stockholders. If (i) no annual meeting was held in the
previous year, (ii) 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 (iii) the upcoming meeting is not an annual meeting, 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.

     The bylaws of WORLDxCHANGE provide that upon request in writing that a
special meeting of shareholders be called for any proper purpose, notice shall
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 nor

                                       202
<PAGE>   216

more than 60 days after receipt of the request. The notice shall specify the
general nature of the business to be transacted at the meeting, and no other
business may be transacted at such meeting.

     Supermajority voting requirements.  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 (Amendments), Article
Four (No Cumulative Voting) or Article Five (Election and Term of Directors).
World Access' certificate of incorporation requires the approval of the holders
of at least 75% of the combined voting power of its stockholders to alter, amend
or repeal Article IX (Management) of the certificate of incorporation, or to
adopt any provision in the certificate of incorporation or bylaws that would be
inconsistent with that article.

     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:

          (i) prior to 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;

          (ii) 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

          (iii) at or subsequent to 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:

          (i) 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;

          (ii) 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;

          (iii) any transaction that results in the issuance or transfer by the
     corporation of any stock of the corporation to the interested stockholder;

          (iv) 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

          (v) 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.
                                       203
<PAGE>   217

     Inspection of shareholder list.  Both California and Delaware law allow any
shareholder to inspect and copy the shareholder list for a purpose reasonably
related to such person's interest as a shareholder. 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. Delaware law also 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. However, Delaware
law contains no provisions comparable to the absolute right of inspection
provided by California law to certain large shareholders.

     WORLDxCHANGE's bylaws mirror the California statutory provisions with
respect to inspection of shareholder lists. World Access' bylaws mirror the
Delaware statutory provisions with respect to inspection of shareholder lists.

     Dividends and repurchases of shares.  California law dispenses with the
concepts of par value of shares as well as statutory definitions of capital,
surplus and the like. The concepts of par value, capital and surplus exist under
Delaware law.

     Under California law, a corporation may not make any distribution to its
shareholders unless either: (i) the corporation's retained earnings immediately
prior to the proposed distribution equal or exceed the amount of the proposed
distribution; or (ii) 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 (not including deferred taxes, deferred income and other
deferred credits), 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.

     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.

     Mergers.  Both California and Delaware law generally require that a
majority of the holders of the stock of each of the acquiring and target
corporations approve statutory mergers. Delaware law does not require a
stockholder vote of the surviving corporation in a merger (unless the
corporation provides otherwise in its certificate of incorporation) if (i) the
merger agreement does not amend the existing certificate of incorporation, (ii)
each share of the surviving corporation outstanding before the merger is an
identical outstanding share after the merger, and (iii) either (a) no shares of
common stock of the surviving corporation and no shares, securities or
obligations convertible into such stock are to be issued or delivered under the
plan of merger, or (b) the number of shares to be issued by the surviving
corporation in the merger does not exceed 20% of the shares outstanding
immediately prior to the merger. California law contains a similar exception to
its voting requirements for reorganizations where shareholders or the
corporation itself, or both, immediately prior to the reorganization own
immediately after the reorganization equity securities constituting more than
five-sixths of the voting power of the surviving or acquiring corporation or its
parent entity.

     Both California and Delaware law also require that a sale of all or
substantially all of the assets of a corporation be approved by a majority of
the voting shares of the corporation transferring such assets.

     With certain exceptions, California law also requires that mergers,
reorganizations, certain sales of assets and similar transaction be approved by
a majority vote of each class of shares outstanding. By contrast, Delaware law
generally does not require class voting, except in certain transactions
involving an

                                       204
<PAGE>   218

amendment to the certificate of incorporation which adversely affects a specific
class of shares. World Access' certificate of incorporation does not, except in
limited circumstances, require class voting.

     Dissenters'/Appraisal rights.  Under both California and Delaware law, a
shareholder of a corporation participating in certain major corporate
transactions may, under varying circumstances, be entitled to dissenters' rights
pursuant to which such shareholder may receive cash in the amount of the fair
market value of his, her or its shares in lieu of the consideration he, she or
it would otherwise receive in the transaction. Under Delaware and California law
such fair market value is determined exclusive of any element of value arising
from the accomplishment or expectation of the merger or consolidation.

     Under Delaware law, appraisal rights are not available (i) with respect to
the sale, lease or exchange of all or substantially all of the assets of a
corporation, (ii) with respect to a merger or consolidation by a corporation
whose shares are either listed on a national securities exchange or are held of
record by more than 2,000 holders if such stockholders receive only shares of
the surviving corporation or shares of any other corporation which are either
listed on a national securities exchange or held of record by more than 2,000
holders, plus cash in lieu of fractional shares, or (iii) to stockholders of a
corporation surviving a merger if, among other conditions, no vote of the
stockholders of the surviving corporation is required to approve the merger
because the merger agreement does not amend the existing certificate of
incorporation, each share of the surviving corporation outstanding prior to the
merger is an identical outstanding or treasury share after the merger, and the
number of shares to be issued in the merger does not exceed 20% of the shares of
the surviving corporation outstanding immediately prior to the merger, unless
otherwise provided in the certificate of incorporation.

     The limitations on the availability of appraisal rights under California
law are different from those under Delaware law. Shareholders of a California
corporation whose shares are listed on a national securities exchange generally
do not have such appraisal rights unless the holders of at least 5% of the class
of outstanding shares claim the right or the corporation or any law restricts
the transfer of such shares. Appraisal rights are also unavailable if the
shareholders of a corporation or the corporation itself, or both, immediately
prior to the merger will own immediately after the reorganization equity
securities constituting more than 83.3% (or five-sixths) of the voting power of
the surviving or acquiring corporation or its parent entity. California law
generally affords appraisal rights in sale of assets reorganizations.

     Dissolution.  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. 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.

     The foregoing is an attempt to summarize the material differences in the
corporation laws of California and Delaware, the WORLDxCHANGE articles of
incorporation and the World Access amended certificate of incorporation, the
WORLDxCHANGE bylaws and the World Access bylaws, and does not purport to be a
complete list of differences in the rights and remedies of holders of shares of
California, as opposed to Delaware, corporations and shareholders or
stockholders of WORLDxCHANGE and World Access in particular. Such differences
can be determined in full by reference to California law, to Delaware law and to
the WORLDxCHANGE articles of incorporation and the World Access amended
certificate of incorporation and the WORLDxCHANGE bylaws and the World Access
bylaws. In addition, the laws of California and Delaware provide that provisions
in the charter or bylaws of the corporation may modify the statutory provisions
that affect various rights of holders of shares.

PREFERRED STOCK

     The World Access amended certificate of incorporation authorizes the board
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 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, and 184,000 shares designated as Series D preferred stock are
issued and outstanding. The material terms of the Series A preferred stock, the
Series C preferred stock and the Series D 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.

     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

                                       206
<PAGE>   220

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.

     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

                                       207
<PAGE>   221

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 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
                                       208
<PAGE>   222

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.

                      MANAGEMENT OF THE COMBINED COMPANIES

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 companies, and Walter J. Burmeister will serve as the
President of the combined companies. It is anticipated that the other current
executive officers of World Access will continue as executive officers of the
combined companies 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.

                                   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

     The World Access board of directors has adopted a resolution unanimously
approving, deeming advisable 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.

                                       210
<PAGE>   224

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 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 43,892,342 shares of common stock.

     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. In addition, an increase in the number of shares of common stock
authorized for issuance is required in order for World Access to complete both
the STAR merger and the WORLDxCHANGE merger. 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.

     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 and Series D 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 APPROVES, RECOMMENDS AND DEEMS ADVISABLE
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 AND 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

     The World Access board of directors has adopted a resolution unanimously
approving, deeming advisable 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 and
to end the classification of the World Access board of directors.

     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
                                       211
<PAGE>   225

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.

     In addition, 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. 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.

     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 and Series D 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 the 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 APPROVES, RECOMMENDS AND DEEMS ADVISABLE
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 AND 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 6

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 AND TO CHANGE THE PERFORMANCE CRITERIA UNDER THE PLAN

     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 (the "Warrant 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.

DESCRIPTION OF PROPOSED THIRD 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 May 22,
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
(i) 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 and (ii) change the performance criteria
of World Access common stock under the Warrant Plan. If the proposed amendment
is approved by the World Access stockholders, these changes will be effective as
of April 25, 2000.

     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, and 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 increase in the authorized shares under the
Warrant Plan and 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 Warrant Plan will provide World Access with
approximately $4.7 million of new capital in the future, assuming full exercise
of all outstanding warrants. In addition, the nonqualified nature of the
warrants may result in significant future tax deductions for World Access equal
to the difference between the market value and exercise price of the warrants on
the dates of exercise.

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.
                                       213
<PAGE>   227

     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 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 (i) if World Access is to
be consolidated with or acquired by another entity in a merger, (ii) upon the
sale of substantially all of World Access's assets or the sale of at least 90%
of the outstanding World Access common stock to a third party, (iii) upon the
merger or consolidation of World Access with or into any other corporation or
the merger or consolidation of any corporation with or into World Access (in
which consolidation or merger the stockholders of World Access receive
distributions of cash or securities as a result thereof), or (iv) upon the
liquidation or dissolution of World Access.

     The World Access board has authority to: (i) determine, upon review of
relevant information and in accordance with the Warrant Plan, the fair market
value of the World Access common stock, (ii) interpret the Warrant Plan, (iii)
prescribe, amend and rescind rules and regulations relating to the Warrant Plan,
(iv) 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 (v) 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 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.
                                       214
<PAGE>   228

     As of May 22, 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 May 22, 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 6 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 and Series D preferred stock, voting
as a single class. If approved by the World Access stockholders, the amendment
to the World Access Directors' Warrant Incentive Plan will become effective upon
such approval.

THE WORLD ACCESS BOARD OF DIRECTORS APPROVES AND 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 AND TO CHANGE THE PERFORMANCE
CRITERIA OF WORLD ACCESS COMMON STOCK UNDER THE PLAN.

                     PRINCIPAL STOCKHOLDERS OF WORLD ACCESS

     World Access' only issued and outstanding classes of voting securities are
common stock, Series A preferred stock, Series C preferred stock and Series D
preferred stock. As of May 22, 2000, there were 60,101,658 shares of World
Access common stock issued and outstanding; 50,000 shares of Series A preferred
stock issued and outstanding (convertible to 4,347,826 shares of World Access
common stock); 350,260 shares of Series C preferred stock issued and outstanding
(convertible into 17,186,451 shares of World Access common stock) and 184,000
shares of Series D preferred stock issued and outstanding (convertible into
10,222,222 shares of World Access common stock).

                                   PROPOSAL 7

                       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

                                       218
<PAGE>   232

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.

THE BOARD OF DIRECTORS OF WORLD ACCESS UNANIMOUSLY RECOMMENDS THAT THE
STOCKHOLDERS OF WORLD ACCESS VOTE "FOR" THE ELECTION OF STEPHEN J. CLEARMAN AND
JOHN D. PHILLIPS AS DIRECTORS.

total number of meetings of the World Access board which such director was

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,

     The Compensation Committee, which presently consists of Messrs. Clearman,

     The World Access board has not established a separate committee of its
members to nominate candidates for election as directors.

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

                                       221
<PAGE>   235

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. 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.

(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.

EXECUTIVE EMPLOYMENT AGREEMENTS

     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
Chmar, its Executive Vice President and Secretary, and Mark A. Gergel, its
Executive Vice President and Chief Financial Officer. Mr. Phillips' employment
agreement provides for a base salary of $625,000 per year. The agreement further
provides that Mr. Phillips 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. 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
is terminated (i) by World Access without cause or (ii) by Mr. Chmar for good
reason, Mr. Chmar 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

options, warrants and

                                       225
<PAGE>   239

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.

     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.

     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:

          (i) 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; (ii) 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; (iii) any failure to pay the employee any compensation or
     benefits to which he is entitled within five days of the date due; (iv)
     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; (v) 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; (vi) the insolvency or
     the filing of a petition for bankruptcy by World Access; (vii) 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
     (viii) any breach by World Access of any provision of an employment
     agreement.

                                       226

     A change in control shall have occurred if: (i) a majority of the directors
of World Access shall be persons other than persons: (A) for whose election
proxies shall have been solicited by the board, or (B) 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; (ii)
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 group acting in concert
for the purpose of acquiring, holding or disposing of voting stock of World
Access, which group does not include the employee; or (iii) there shall have
occurred: (A) a merger or consolidation of World Access with or into another
corporation (other than (1) a merger or consolidation with a subsidiary of World
Access or (2) a merger or consolidation in which (a) the holders of voting stock
of World Access immediately prior to the merger as a class continue to hold
immediately after the merger at least a majority of all outstanding voting power
of the surviving or resulting corporation or its parent and (b) all holders of
each outstanding class or series of voting stock of World Access immediately
prior to the merger or consolidation have the right to receive substantially the
same cash, securities or other property in exchange for their voting stock of
World Access as all other holders of such class or series); (B) a statutory
exchange of shares of one or more classes or series of outstanding voting stock
of World Access for cash, securities or other property; (C) the sale or other
disposition of all or substantially all of the assets of World Access, in one
transaction or a series or transactions; or (D) the liquidation or dissolution
of World Access; unless more than 25% of the voting stock, or the voting equity
interest, of the surviving corporation or the corporation or other entity
acquiring all or substantially all of the assets of World Access (in the case of
a merger, consolidation or disposition of assets) or of World Access or its
resulting parent corporation (in the case of a statutory share exchange) is
beneficially owned by the employee or a group that includes the employee.

     John D. Phillips and Armstrong International Telecommunications, Inc. have
entered into a letter agreement, pursuant to which Mr. Phillips has agreed not
to sell or transfer, directly or indirectly, any shares of World Access common
stock held by him without the prior written consent of Armstrong International
Telecommunications for so long as Armstrong International Telecommunications or
any of its affiliates remains a stockholder of World Access. The provisions of
the letter agreement terminate upon (i) Mr. Phillips' death or disability, (ii)
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, (iii) 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 (iv) 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: (i) a cash
payment equal to 0.75% of the gross consideration received by World Access upon
the sale of the NACT Switching Division; (ii) 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 (iii) 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
                                       227

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.

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 (i) earnings per share; (ii) revenue; (iii) earnings before interest, taxes,
depreciation and amortization; and (iv) 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: (i) $50.0
million investment by The 1818 Fund III; (ii) acquisition of Comm/Net; (iii)
FaciliCom merger; (iv) $75.0 million private placement by institutional
investors; (v) pending acquisition of Long Distance International; and (vi)
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
Annual

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

     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.

               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.

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.

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.

  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. Estimated credit
losses are provided for in the financial statements at the same time the
corresponding revenue is recognized. 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, including equipment under capital
leases, 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) or the term of the related lease (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.

  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.

  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.

  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.

  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. ("CTS") and WORLDxCHANGE Limited ("WxL"), 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 WxL. The accompanying pooled consolidated
financial statements are derived from the combined historical financial
statements of CTS, WxL and WORLDxCHANGE. All significant intercompany accounts
and transactions have been eliminated.

     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

       AND FOR THE SIX MONTHS ENDED MARCH 31, 1999 AND 2000 IS UNAUDITED)

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.

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

  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.

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
Internal Revenue Code if certain cumulative changes occur in WORLDxCHANGE's
ownership.

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.

       AND FOR THE SIX MONTHS ENDED MARCH 31, 1999 AND 2000 IS UNAUDITED)

  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 subject to limitations.
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.

 (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)

     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):

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. Total payments totaling monthly of
which $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%.

                          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>   277

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>   278

     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.

                                   ARTICLE II

                            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>   280

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>   281

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>   282

        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>   283

        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.

        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 Laws"),

        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>   284

        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
     supplied by WAXS for inclusion or incorporation by reference in the Joint
     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.

          (f) WAXS Board Approval.  The Board of Directors of WAXS, by
     resolutions duly adopted by unanimous vote at a meeting duly called and
     held and not subsequently rescinded or modified in any way (the "WAXS Board
     Approval"), has duly (i) determined that this Agreement, the Merger and the
     other transactions contemplated hereby are fair to and in the best
     interests of WAXS and its stockholders, (ii) approved this Agreement, the
     Merger and the other transactions contemplated hereby and (iii) declared
     the advisability of this Agreement, the Merger and the other transactions
     contemplated hereby, and, further, (iv) recommended that the stockholders
     of WAXS approve and adopt this Agreement, the Merger and the other
     transactions contemplated hereby and directed that this Agreement and the
     transactions contemplated hereby be submitted for consideration by WAXS's
     stockholders at the WAXS Stockholders Meeting.

          (g) Required WAXS Stockholder Vote.  The affirmative vote of holders
     of shares of WAXS Common Stock, Series A Preferred Stock and Series C
     Preferred Stock, voting together as a single class, representing a majority
     of the outstanding shares of WAXS Common Stock, Series A Preferred Stock
     and Series C Preferred Stock (the "Required WAXS Vote"), is the only vote
     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

     (iii) declared the advisability of this Agreement, the Merger and the other
     transactions contemplated hereby, and, further, (iv) recommended that WAXS
     adopt this Agreement and approve the Merger and the other transactions
     contemplated hereby and directed that this Agreement and the transactions
     contemplated hereby be submitted for consideration by WAXS at a meeting
     duly called.

          (i) Required Merger Sub Stockholder Vote.  The affirmative vote of
     WAXS, as sole stockholder of Merger Sub, is the only vote of the holders of
     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>   286

     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
        for Taxes that WAXS and its Subsidiaries is contesting in good faith

        refund litigation or matter in controversy with respect to any Taxes of
        WAXS and its Subsidiaries that might reasonably be expected to result in

<PAGE>   287

          (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
     contracts filed with the WAXS SEC Reports and the contracts listed on
     Section 3.1(p) of the WAXS Disclosure Schedule are valid, binding and are
     in full force and effect and enforceable in accordance with their
     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.

          (b) Capital Structure.

             (1) The authorized capital stock of STAR consists of (A) 50,000,000
        shares of STAR Common Stock, of which 58,683,131 shares are outstanding
        and no shares are held in the treasury of STAR and (B) 5,000,000 shares
        of preferred stock, par value $0.001 per share, of which no shares are
        outstanding. All issued and outstanding shares of the capital stock of
        STAR are duly authorized, validly issued, fully paid and nonassessable,
        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
        Schedule lists the exercise price and vesting schedule for each STAR
        Stock Option.

             (2) No bonds, debentures, notes or other indebtedness of STAR
        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,
        registrations, declarations and filings referred to in paragraph (3)
        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>   289

        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
        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, STAR 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 STAR 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 STAR.

          (e) Information Supplied.  None of the information supplied or to be
     supplied by STAR for inclusion or incorporation by reference in the Joint
     Proxy Statement/Prospectus will, on the date it is first mailed to WAXS's
     or STAR's stockholders, as applicable, or at the time of the WAXS
     Stockholders Meeting (as defined in Section 5.1) 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.

          (f) Board Approval.  The Board of Directors of STAR, by resolutions
     duly adopted by unanimous vote at a meeting duly called and held and not
     subsequently rescinded or modified in any way (the "STAR Board Approval"),
     has duly (i) determined that this Agreement, the Merger and the other
     transactions contemplated hereby are fair to and in the best interests of
     STAR and its stockholders, (ii) approved this Agreement, the Merger and the
     other transactions contemplated hereby and (iii) declared the advisability
     of this Agreement, the Merger and the other transactions contemplated
     hereby, and, further, (iv) recommended that the stockholders of STAR
     approve and adopt this Agreement, the Merger and the other transactions
     contemplated hereby and directed that
                                      A-14
<PAGE>   290

     this Agreement and the transactions contemplated hereby be submitted for
     consideration by STAR's stockholders.

          (g) Required Stockholder Vote.  The affirmative vote of the holders of
     a majority of the outstanding shares of STAR Common Stock (the "Required
     STAR Vote") is the only vote of the holders of any class or series of STAR
     capital stock necessary to adopt this Agreement and approve the Merger and
     the other transactions contemplated hereby.

          (h) Litigation: Compliance with Laws.

             (1) There is no suit, investigation, action or proceeding pending
        or, to the Knowledge of STAR, threatened, against or affecting STAR or
        any Subsidiary of STAR having, or which would have a Material Adverse
        Effect on STAR, nor is there any judgment, decree, injunction, rule or
        order of any Governmental Entity or arbitrator outstanding against STAR
        or any Subsidiary of STAR having, or which would have a Material Adverse
        Effect on STAR.

             (2) Except as would not have a Material Adverse Effect on STAR,
        STAR 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, necessary for the operation of the businesses of
        STAR and its Subsidiaries (the "STAR Permits"). Such STAR permits are
        valid and in full force and effect and STAR and its Subsidiaries are in
        compliance with the terms of the STAR 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 STAR. The businesses of STAR and its
        Subsidiaries are not being conducted in violation of, and STAR has not
        received any notices of violations with respect to, any law, ordinance
        or regulation of any Governmental Entity, except for possible violations

             (2) STAR and all STAR Affiliates have complied with their
        respective substantive obligations with respect to all STAR Employee
        Benefit Plans (including, but not limited to, (i) filing or distributing
        all reports or notices required by ERISA or the Code and (ii) complying
        with all requirements of Part 6 of Title I of ERISA and Code Section
        4980B) and have maintained the STAR 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 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
        Benefit Plan. No statement, either oral or written, has been made by
        STAR or any STAR Affiliate (or any agent of either) to any Person
        regarding any STAR Employee Benefit Plans that is not in accordance with
        the terms of that plan that would have a Material Adverse Effect on

        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.

             (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.

        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).

             (8) Section 3.2(j)(8) of the STAR Disclosure Schedule sets forth 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

     use of any Intellectual Property by STAR and its Subsidiaries does not

     the Knowledge of STAR, no Person is challenging, infringing on or otherwise

     and (iv) neither STAR nor any of its Subsidiaries has received any written
     notice of any pending claim with respect to any Intellectual Property used
     by STAR and its Subsidiaries and to STAR's Knowledge, no Intellectual

     enforced in a manner that would result in the abandonment, cancellation or
     unenforceability of such Intellectual Property.

          (l) 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

          (l) Litigation.  STAR shall not and shall not permit any of its
     Subsidiaries to settle or, compromise any litigation, except where the
     amount paid or payable, in each case, does not exceed $200,000.

     4.2 Control of STAR's Business.  Except as provided in Section 5.9, nothing
contained in this Agreement shall give WAXS, directly or indirectly, the right
to control or direct STAR's operations prior to the Effective Time. Prior to the
Effective Time, STAR shall exercise, consistent with the terms and conditions of
this Agreement, complete control and supervision over its operations.

                             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>   297

     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>   298

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>   299

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>   301

     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
if this Agreement is terminated or if the Merger is not consummated for any
reason whatsoever, such Confidentiality Agreement shall thereafter remain in
full force and effect in accordance with its terms.

     5.14 Compliance with Dissenters' Rights Statute.  STAR shall comply with
all procedures and requirements applicable to it under Section 262 of the DGCL.

     5.15 Interim Financing.  The parties have agreed that WAXS will make
available up to $25,000,000 in secured financing to STAR and up to $10,000,000
in secured financing to STAR's subsidiary, STAR Telecommunications GmbH,
(collectively, the "Interim Financing") pursuant to the terms of the Loan
Documents (as defined below). The Interim Financing will mature at the earlier
of one year from the date hereof and ninety (90) days after any termination of
this Agreement (other than a termination due to STAR's breach or default under
this Agreement which will result in the Interim Financing becoming immediately
due and payable). The Interim Financing will be made pursuant to, and subject to
the finalization of, appropriate loan and security documents (the "Loan
Documents") substantially in the form of, and as contemplated by, the draft Loan
Documents distributed to STAR on or prior to the date hereof.

     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.

          (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
     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>   303

     (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.

     6.3 Additional Conditions to Obligations of STAR.  The obligations of STAR
to effect the Merger are subject to the satisfaction of, or waiver by STAR, on
or prior to the Closing Date of the following additional conditions:

          (a) Representations and Warranties.  Each of the representations and
     warranties of WAXS set forth in this Agreement shall be true and correct as
     of the date of this Agreement and as of the Closing Date as though made on
     and as of the Closing Date (except to the extent in either case that such
     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.

                                      A-28
<PAGE>   304

          (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
     with the establishment thereof.

                                  ARTICLE VII

                           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
     to
                                      A-29
<PAGE>   305

     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
     (1) commences a voluntary case under any applicable bankruptcy, insolvency
     or other similar law now or hereafter in effect, or consents to the entry
     of an order for relief in an involuntary case under any such law, (2)
     consents to the appointment of or taking possession by a receiver,
     liquidator, assignee, custodian, trustee, sequestrator or similar official
     of STAR or any of its Subsidiaries or for all or a material portion of the
     property or assets of STAR or any of its Subsidiaries or (3) effects any
     general assignment for the benefit of creditors or (Y) a Governmental
     Entity having jurisdiction enters a decree or order for (a) relief in

     under any applicable bankruptcy, insolvency or other similar law now or
     hereafter in effect, (b) appointment of a receiver, liquidator, assignee,
     custodian, trustee, sequestrator or similar official of STAR or any of its
     Subsidiaries or for all or a material portion of the property and assets of

     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
     shall survive such termination and except that,
                                      A-30
<PAGE>   306

     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
     7.1(h), STAR shall, prior to such termination, pay to WAXS $14,000,000 in
     immediately available funds (the "Termination Fee");

          (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
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.

the parties and delivered to the other party, it being understood that both

     8.5 Entire Agreement; No Third Party Beneficiaries.

          (a) This Agreement and the Confidentiality Agreement constitute the
     entire agreement and supersede all prior agreements and understandings,

     of Intent, dated December 17, 1999, between WAXS and STAR, among the

<PAGE>   308

          (b) This Agreement shall be binding upon and inure solely to the
     benefit of each party hereto, and nothing in this Agreement, express or
     implied, is intended to or shall confer upon any other Person any right,
     benefit or remedy of any nature whatsoever under or by reason of this
     Agreement, except as provided for in Section 5.12.

     8.6 Governing Law.  This Agreement shall be governed and construed in
accordance with the laws of the State of Delaware (without giving effect to
choice of law principles thereof).

     8.7 Severability.  If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any law or public policy, all
other terms and provisions of this Agreement shall nevertheless remain in full
force and effect so long as the economic or legal substance of the actions
contemplated hereby is not affected in any manner materially adverse to any
party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner in order that the
transactions contemplated hereby are consummated as originally contemplated to
the greatest extent possible.

     8.8 Assignment.  Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto, in whole
or in part (whether by operation of law or otherwise), without the prior written
consent of the other parties, and any attempt to make any such assignment
without such consent shall be null and void. Subject to the preceding sentence,
this Agreement will be binding upon, inure to the benefit of and be enforceable
by the parties and their respective successors and assigns.

     8.9 Submission to Jurisdiction; Waivers.  Each of WAXS and STAR irrevocably
agrees that any legal action or proceeding with respect to this Agreement or for
recognition and enforcement of any judgment in respect hereof brought by the
other party hereto or its successors or assigns may be brought and determined in
the Chancery or other Courts of the State of Delaware, and each of WAXS and STAR
hereby irrevocably submits with regard to any such action or proceeding for
itself and in respect to its property, generally and unconditionally, to the
nonexclusive jurisdiction of the aforesaid courts. Each of WAXS and STAR hereby
irrevocably waives, and agrees not to assert, by way of motion, as a defense,
counterclaim or otherwise, in any action or proceeding with respect to this
Agreement, (i) any right to trial by jury with respect to any action, suit or
proceeding arising out of or relating to this Agreement, the Merger or any other
transaction contemplated hereby, (ii) any claim that it is not personally
subject to the jurisdiction of the above named courts for any reason other than
the failure to lawfully serve process, (iii) that it or its property is exempt
or immune from jurisdiction of any such court or from any legal process
commenced in such courts (whether through service of notice, attachment prior to
judgment, attachment in aid of execution of judgment, execution of judgment or
otherwise), and (iv) to the fullest extent permitted by applicable law, that (a)
the suit, action or proceeding in any such court is brought in an inconvenient
forum, (b) the venue of such suit, action or proceeding is improper and (c) this
Agreement, or the subject matter hereof, may not be enforced in or by such
courts.

     8.10 Enforcement.  The parties agree that irreparable damage would occur in
the event that any of the provisions of this Agreement were not performed in

     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>   316

          (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>   317

     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>   318

     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>   319

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>   320

     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>   321

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>   322

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>   323

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

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>   324

     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

     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>   325

     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.

     3.11 Litigation.  SCHEDULE 3.11 sets forth all litigation, claims, suits,
actions, investigations, indictments or informations, proceedings or
arbitrations, grievances or other procedures (including grand jury
investigations, actions or proceedings, and product liability and workers'
compensation suits, actions or proceedings) pending, or to the knowledge of CTI,
threatened, before any court, commission, arbitration tribunal, or judicial,
governmental or administrative department, body, agency, administrator or
official, grand jury, or any other forum for the resolution of grievances,
against CTI or any of its Subsidiaries or involving any of its or their assets
or business, except for such matters as would not have a Material Adverse Effect
on CTI. Further, except as set forth in SCHEDULE 3.11 and for matters which
would not have a Material Adverse Effect on CTI, there are no material
judgments, orders, writs, injunctions, decrees, indictments or informations,
grand jury subpoenas or civil investigative demands, plea agreements,
stipulations or awards (whether rendered by a court, commission, arbitration
tribunal, or judicial, governmental or administrative department, body, agency,
administrator or official, grand jury or any other forum for the resolution of
grievances) against or relating to CTI or any of its Subsidiaries or involving
any of its or their assets or business. CTI has made available to WAXS all
information requested by WAXS with respect to each pending litigation, claim,
suit, action, investigation, indictment or information, proceeding, arbitration,
grievance or other procedure listed in SCHEDULE 3.11, and the judgements and
informations, grand jury subpoenas and civil investigative demands, plea
agreements, stipulations and awards listed in said Schedule.

     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>   326

     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).
                                      B-13

     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

     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

     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,

     any other Tax authority asserted any claim for Taxes in
                                      B-14
<PAGE>   328

     writing, or to the knowledge of CTI, is threatening to assert any claim for

     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,

     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

     be subject to Taxes in such jurisdiction, (iii) is a "passive foreign
     investment company" within the meaning of the Code, (iv) has participated

          (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

     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

     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

     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

     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>   330

             (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.

all Governmental Entities necessary for the operation of the business of CTI and

<PAGE>   332

          (f) Neither CTI nor any of its Subsidiaries is subject to any contract

without the giving of notice or the lapse of time, or both, (i) violate or
conflict with any of the provisions of any charter document or bylaw of CTI or a

     3.20 Agreements in Full Force and Effect.  Except as expressly set forth in

regulation, order, decree or award of any Governmental Entity or any lease,
agreement, contract, mortgage, note, license, permit, tariff, authorization or
any other instrument to which CTI or a Subsidiary thereof is a party or to which
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.

conducted its business only in the ordinary course, and has not:

     will contain any untrue statement of a material fact or omitted or will

     such reports, 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

     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),

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

material respects with the requirements of the Exchange Act and the rules and
regulations promulgated thereunder.

     terms of the WAXS Permits, except as disclosed in the WAXS SEC Reports or

     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

          (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,

     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

     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>   339

        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

        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.

             (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>   341

        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 V

                                   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>   344

     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>   345

     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).

<PAGE>   346

     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
CTI, taken as a whole, or any purchase or sale of, or tender or exchange offer
for, a material portion of the equity securities of CTI (any such proposal or
offer being referred to herein as an "Acquisition Proposal"). CTI further agrees
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
system or exchange, all WAXS Common Stock issuable pursuant to Article I hereof.
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>   347

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.

<PAGE>   348

          (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.

     Stock as reported on the Nasdaq for the ten (10) consecutive trading days

                                  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
of any representation or warranty of CTI set forth in the certificates to be
provided to WAXS pursuant to Sections 7.2(a) and (b), without regard to the

(iii) any breach of or noncompliance by CTI prior to the Effective Time with any

     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>   352

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

     by Roger Abbott. Prompt notice of such appointment shall be delivered in
     writing by Roger Abbott to WAXS and the Escrow Agent.

                          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>   353

     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>   354

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

     10.6 Modification and Waiver.  Any of the terms or conditions of this

Board of Directors
World Access, Inc.

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>   361

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.

point of view.

Board of Directors
World Access, Inc.

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>   363

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

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
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.

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>   365

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,

[Name of PT-1 acquiror]

March 29, 2000

Star Telecommunications, Inc.
223 E. De La Guerra Street
Santa Barbara, California 93101

Ladies and Gentlemen:

     This letter of intent (the "Letter") sets forth our binding agreement with
respect to the acquisition by [PT-1 acquiror] or one of its affiliates ("[PT-1
acquiror]") from Star Telecommunications, Inc. or one of its affiliates (the
"Seller", and together with [PT-1 acquiror], the "Parties") of all of the assets
relating to or used in connection with the debit card and dial-around businesses
(the "Businesses") operated by the Seller's wholly-owned subsidiary PT-1
Communications, Inc. (together with any subsidiaries thereof, "PT-1"). The
assets acquired by [PT-1 acquiror] hereunder are referred to as the "Assets".

     1. Terms.

     [PT-1 acquiror] will pay to the Seller at the closing of the transactions
contemplated hereby (the "Closing") a purchase price of $150,000,000 in cash
(the "Purchase Price") in exchange for the Seller transferring to [PT-1
acquiror] the Assets, including, without limitation, all cash, cash equivalents,
accounts receivable and other line item asset categories (except for deferred
tax assets) in respect of the Assets set forth on the Balance Sheet (as defined
below) and for the period of PT-1's operation from December 31, 1999 through
Closing; provided that the Purchase Price shall be adjusted upward or downward
to the extent at Closing the net value of the Assets (i.e., total Assets (not
including any deferred tax asset) less Assumed Liabilities (as defined below) as
set forth on an audited balance sheet of PT-1 to be delivered by the accounting
firm of Arthur Andersen as soon as practicable following Closing, and subject to
[PT-1 acquiror's] right to dispute the accuracy of such audited balance sheet)
is greater than or less than $37,223,490 (i.e., the net value thereof set forth
on the Balance Sheet as of December 31, 1999); and provided further that if the
Seller is able, or is reasonably determined by an independent third party
jointly selected by the Parties to be able, to utilize any benefit from its
deferred tax asset set forth on the Balance Sheet, the Purchase Price shall be
reduced by an amount equal to 50% of such benefit (or if such benefit is
determined to be realizable after the Closing, the Seller shall promptly pay
such amount to [PT-1 acquiror] in cash). At Closing [PT-1 acquiror] will assume
only liabilities of PT-1 in respect of the following line items on the Balance
Sheet: (i) Accounts payable and accrued expenses; (ii) Accrued taxes payable;
(iii) Short-Term debt; (iv) Deferred Revenue; and (v) Long-term debt (the
"Assumed Liabilities"). All pre-Closing liabilities other than the Assumed
Liabilities will remain obligations of the Seller.

     2. Financial Information.  The Seller represents and warrants to [PT-1
acquiror] that (a) the balance sheet of PT-1 attached as Exhibit A as of
December 31, 1999 (the "Balance Sheet") and the income statement of PT-1 for the
year ended December 31, 1999 are true and accurate, have been prepared from the
books and records of PT-1 in accordance with United States generally accepted
accounting principles ("GAAP") consistently applied and fairly present in all
material respects the financial condition of PT-1, (b) the Balance Sheet shows
all material liabilities, absolute or contingent, of PT-1 required to be
recorded thereon, (c) the assets shown on the Balance Sheet consist only of the
Assets and (d) since the date of the Balance Sheet, (i) PT-1 has incurred no
liabilities or obligations other than liabilities or obligations incurred in the
ordinary course of business, consistent with the past practices of PT-1 and
which do not and could not, individually or in the aggregate, reasonably be
expected to have a material adverse effect on the business, financial condition
or results of operations of PT-1, the Assets or the Businesses (a "Material
Adverse Effect"), (ii) there has been no Material Adverse Effect and (iii) there
has not occurred any other event, circumstance or condition that has had or
could reasonably be expected to have, individually or in the aggregate, a
Material Adverse Effect.

     3. Negotiation of Definitive Agreements; Exclusivity.

     (a) Good Faith.  The Parties will proceed diligently and in good faith to
negotiate, execute and deliver definitive agreements (including, without
limitation, an asset purchase agreement, employment agreements with key
executives, a shared network services agreement, and other necessary or
desirable services agreements (collectively, the "Agreements")), the present
intent of the Parties being to deliver such Agreements by April 21, 2000
(provided that the failure to so deliver the Agreements by such date shall not
constitute a breach of this Letter), subject in all respects to the approval of
the Parties, verification of legal and factual issues deemed relevant to the
Parties and receipt of requisite regulatory and other approvals or consents. The
Seller shall make all reasonable efforts (i) to assist [PT-1 acquiror] in
identifying key executives of the Seller and PT-1, and recruiting such key
employees and other officers and employees of the Seller and PT-1 identified by
[PT-1 acquiror] for employment by the entity operating the Businesses following
the Closing and (ii) to facilitate conversations and meetings between [PT-1
acquiror] and World Access, Inc. ("WAI") with a view to securing for [PT-1
acquiror] a right of first refusal for the purchase of any business competitive
with the Businesses that is owned and offered for sale by WAI at any time after
the date hereof.

     (b) Terms of the Agreements.  The Agreements will contain, among other
things, representations and warranties, covenants, conditions and
indemnification provisions appropriate for such agreements; provided that (i)
the representations and warranties of the Seller will survive the Closing for
two years (other than those in respect of tax matters, which will survive the
Closing until the expiration of the applicable statute of limitations); (ii) the
Parties will proceed diligently and in good faith to file all documents
necessary to satisfy any applicable waiting period under the Hart-Scott-Rodino
Act; (iii) the Seller will obtain all material third-party consents to the
transactions contemplated hereby prior to Closing (which condition may be waived
by [PT-1 acquiror] in its absolute discretion); (iv) the Seller will represent
and warrant (and hereby represents and warrants) that the accounts receivable of
PT-1 shown on the Balance Sheet and any more recent financial statements
furnished to [PT-1 acquiror] are valid, genuine and fully collectible, and
adequate reserves have been provided therefor under GAAP; and (v) the Seller
shall use its reasonable commercial efforts to identify, with [PT-1 acquiror],
and to cause certain of the Seller's key executives to enter into exclusive
employment agreements with [PT-1 acquiror], or to agree to not, directly or
indirectly, engage in any business competitive with the Businesses and [PT-1
acquiror], and the Seller will not, and shall use its reasonable commercial
efforts to cause such key executives to not, solicit or hire away any of the
employees of [PT-1 acquiror] or its affiliates, in the case of each of the
foregoing for a period of three years following the Closing. Promptly following
the execution of this Letter, Christopher Edgecomb, the Chief Executive Officer
of the Seller, shall deliver his agreement, in his capacity as a shareholder, to
at all times vote his shares of the Seller in favor of the transactions
contemplated hereby.

     (c) No Other Arrangements.  None of the Seller or its affiliates, officers,
directors, employees or other agents shall (i) directly or indirectly, solicit,
discuss or encourage the making of any inquiry, offer or proposal which
constitutes or is reasonably likely to lead to any Transaction Proposal (as
defined below); or (ii) accept or entertain an offer by any person, other than
[PT-1 acquiror], or enter into discussions with, or provide information to any
person, other than [PT-1 acquiror], concerning any Transaction Proposal. The
Seller agrees that it will promptly notify [PT-1 acquiror] after receipt of any
Transaction Proposal of the material terms thereof and any ongoing developments
with respect thereto. For purposes of this Letter, "Transaction Proposal" shall
mean any proposal or offer to acquire an equity interest in, or a substantial
portion of, PT-1, the Businesses or the Assets, whether by merger, sale of
equity interests, asset purchase or other transaction, other than pursuant to
the transactions contemplated by this Letter.

     4. Due Diligence; Access.

     The transactions contemplated herein are subject to the completion by [PT-1
acquiror] of a due diligence review of PT-1, the Businesses and the Assets
satisfactory to [PT-1 acquiror] in its absolute discretion. [PT-1 acquiror] will
have the right to, and Seller shall provide to [PT-1 acquiror], reasonable
access during normal business hours to the facilities, personnel, records,
contracts and other documents of

                                       F-2
<PAGE>   369

PT-1, including, without limitation, information related to financial,
accounting, commercial, legal, environmental, regulatory and employee benefits
matters as reasonably requested and necessary to complete such review. Any
investigation pursuant to this Section shall be conducted so as not to interfere
unreasonably with the conduct of the business of PT-1.

     5. Confidentiality; Public Announcements.

     The Parties agree (i) not to disclose (and to cause their affiliates and
their directors, officers, employers and agents not to disclose) to any third
party (other than to WAI and to directors, officers, employers and agents on a
need to know basis) any matters in respect of this Letter, and (ii) not to make
any announcement regarding the transactions contemplated hereby without the
prior written consent of the other Party.

     6. Closing Date; Interim Operations.

     The parties shall proceed diligently and in good faith to complete the
Closing (including by completing and facilitating the completion of all
pre-Closing actions required or contemplated hereby) by the earlier of (i) the
closing of the acquisition of the Seller by WAI or (ii) June 30, 2000. At all
times prior to the Closing of the transactions contemplated hereby, the Seller
shall, and shall cause PT-1 to, conduct the business and operations of PT-1 in
the ordinary course consistent with past practice.

     7. Miscellaneous.

     (a) Injunctive Relief; Liquidated Damages.  Each Party acknowledges and
agrees that the other Party would be irreparably damaged in the event that any
of the terms of this Letter are not performed in accordance with their specific
terms or are otherwise breached. Accordingly, each Party agrees that the other
party shall be entitled to an injunction, specific performance or other
equitable relief to prevent breaches of the terms of this Letter and to enforce
specifically such terms in addition to any other remedies to which the Parties
may be entitled, at law or in equity. Without limiting the foregoing, each Party
agrees to indemnify and hold harmless the other Party (the "Indemnified Party")
with respect to any losses or damages suffered by the Indemnified Party arising
out of any breach of the terms of this Letter; provided that in addition to and
not in limitation of the foregoing indemnity and the other remedies available to
[PT-1 acquiror], and in order to induce [PT-1 acquiror] to enter into this
Letter, the Seller hereby agrees that in the event that the Seller fails or
refuses to consummate the transactions contemplated hereby with [PT-1 acquiror]
for any reason (other than (i) the failure to obtain necessary regulatory
approval for the transactions contemplated hereby, (ii) the failure of a
majority of the Seller's shareholders entitled to vote to approve the
transactions contemplated hereby (provided that if within 12 months of such
failure to approve the Assets or PT-1 are directly or indirectly sold to a third
party other than [PT-1 acquiror], the exclusion contained in this clause (ii)
shall not apply), (iii) [PT-1 acquiror's] breach of the material terms and
conditions of the Agreements, or (iv) the mutual written consent of the
Parties), the Seller shall promptly upon demand pay to [PT-1 acquiror]
$5,850,000 in cash as liquidated damages (the "Liquidated Damages Amount"). The
Seller hereby acknowledges that the Liquidated Damages Amount is reasonable and
not punitive in nature.

     (b) Authorization.  Each Party represents and warrants to the other Party
that this Letter has been duly authorized by such Party and constitutes its
valid and binding agreement.

     (c) Governing Law.  This Letter shall be governed by the laws of the State
of New York without regard to the conflicts of law principles thereof and shall
be enforceable in the state and federal courts of the State of New York, to
which exclusive jurisdiction the Parties hereby submit.

     (d) Counterparts.  This Letter may be executed in counterparts, each of
which shall be deemed to be an original, but all of which together shall
constitute one and the same document.

     (e) Assignment.  This Letter may not be assigned by any party hereto
without the prior written consent of the other Party hereto.

              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.

<PAGE>   372

          (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
                                       G-2
<PAGE>   373

     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
                                       G-3
<PAGE>   374

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

                                       H-1
<PAGE>   376

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

                                       H-2
<PAGE>   377

(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.

<PAGE>   378

     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
                                       H-4
<PAGE>   379

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.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

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

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

     (2) The registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement 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) 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.

     (4) The undersigned registrant hereby undertakes 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.

     (5) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

                VOTING AND STOCK TRANSFER RESTRICTION AGREEMENT


         This VOTING AND STOCK TRANSFER RESTRICTION AGREEMENT (this
"Agreement"), dated as of February 11, 2000, is made and entered into among
World Access, Inc., a Delaware corporation ("WAXS"), and Samer Tawfik
("Stockholder").

         WHEREAS, WAXS and STAR Telecommunications, Inc. ("STAR") propose to
enter into an Agreement and Plan of Merger, dated as of the date hereof (as the
same may be amended or supplemented, the "Merger Agreement"; capitalized terms
used but not defined herein shall have the meanings set forth in the Merger
Agreement ), providing for a business combination between WAXS and STAR (the
"Transaction"), upon the terms and subject to the conditions set forth in the
Merger Agreement;

         WHEREAS, Stockholder owns 9,183,711 shares of STAR Common Stock (such
shares of STAR Common Stock, together with any other shares of STAR capital
stock of which Stockholder acquires beneficial ownership after the date hereof
and during the term of this Agreement whether upon the exercise of options,
warrants or rights, the conversion or exchange of convertible or exchangeable
securities, or by means of purchase, dividend, distribution or otherwise, being
collectively referred to herein as the "STAR Subject Shares");

         WHEREAS, in connection with its approval of the Merger Agreement and
the Transaction, the Board of Directors of STAR has approved this Agreement in
accordance with Section 203 of the DGCL; and

         WHEREAS, as a condition to its willingness to enter in the Merger
Agreement, WAXS has requested that Stockholder enter into this Agreement;

         NOW, THEREFORE, in consideration of the premises and the
representations, warranties and agreements contained herein, the parties agree
as follows:

         1.       Representations and Warranties of Stockholder.  Stockholder
hereby represents and warrants to WAXS as follows:

                  (a)      Authority; No Conflicts. Stockholder has the legal
         capacity and all requisite power and authority to enter into this
         Agreement, to perform his obligations hereunder and to consummate the
         transactions contemplated hereby. This Agreement has been duly
         authorized, executed and delivered by Stockholder and constitutes a
         valid and binding obligation of Stockholder enforceable in accordance
         with its terms. No filing with, and no permit, authorization, consent
         or approval of, any Governmental Entity or any other Person


<PAGE>   2

is necessary for the execution of this Agreement by Stockholder and the
consummation by Stockholder of the transactions contemplated hereby and none of
the execution and delivery of this Agreement by Stockholder, the consummation
of the transactions contemplated hereby or compliance with the terms hereof by
Stockholder will conflict with, or result in any violation of, or default (with
or without notice or lapse of time or both) under any provision of any
agreement to which Stockholder is a party, including any voting agreement,
stockholders agreement, voting trust, trust agreement, pledge agreement, loan
or credit agreement, note, bond, mortgage, indenture, lease or other agreement,
instrument, permit, concession, franchise or license or violate any judgment,
order, notice, decree, statute, law, ordinance, rule or regulation applicable
to Stockholder or to his property or assets.

         (b)      The STAR Subject Shares. Stockholder is the record and
beneficial owner of, and has good and marketable title to, 9,183,711 shares of
STAR Common Stock, free and clear of any encumbrances, agreements, adverse
claims, liens or other arrangements with respect to the ownership of or the
right to vote or dispose of such shares of STAR Common Stock, other than with
respect to various margin positions taken by Stockholder with respect to a
portion of such shares that have been pledged pursuant to the margin loan
agreements set forth on Schedule 1 hereto (the "Margin Requirements"). Other
than such 9,183,711 shares of STAR Common Stock, Stockholder does not
beneficially or of record own any shares of STAR capital stock or securities
convertible or exchangeable for shares of STAR capital stock. Stockholder has
the sole right and power to vote and, subject to the Margin Requirements,
dispose of such shares of STAR Common Stock. None of such 9,183,711 shares of
STAR Common Stock are subject to any voting trust or other agreement,
arrangement or restriction with respect to the voting or transfer of any of the
shares of STAR Common Stock, except as contemplated by this Agreement and
except with respect to the Margin Requirements.

         (c)      STAR Stock Options. Stockholder does not own, as of the date
hereof, and will not acquire prior to the Effective Time, any STAR Stock
Options.

2.       Covenants of Stockholder. Until the termination of this Agreement
in accordance with Section 4 hereof, Stockholder agrees as follows:

         (a)      Voting of STAR Subject Shares. At any meeting of stockholders
of STAR or at any adjournment thereof or in any other circumstances upon which
Stockholder's vote, consent or other approval (including by written consent) is
sought, Stockholder shall vote all of the STAR Subject Shares then beneficially
owned by Stockholder (i) in favor of the Transaction and the adoption and the
approval of the Merger Agreement and each of the other transactions
contemplated by the Merger Agreement, (ii) against any action or agreement that
would result in a breach of any covenant, representation or warranty or any
other obligation or agreement of STAR under the Merger Agreement and (iii)
against any action or agreement that would impede, interfere with, delay or
postpone or that would reasonably be expected to discourage the Transaction,
including, but not limited to: (A) any

                                       2
<PAGE>   3

extraordinary corporate transactions (other than the Transaction), such as a
merger, consolidation or other business combination involving STAR or its
Subsidiaries, a sale or transfer of a material amount of assets of STAR or its
Subsidiaries or a reorganization, recapitalization or liquidation of STAR or
its Subsidiaries; (B) any amendment of STAR's certificate of incorporation or
bylaws or other proposal or transaction involving STAR or any of its
Subsidiaries, which amendment or other proposal or transaction would in any
manner impede, prevent or nullify the Transaction, the Merger Agreement or any
of the other transactions contemplated by the Merger Agreement or change in any
manner the voting rights of any class of STAR capital stock; or (C) any change
in the management or board or directors of STAR.

         (b)      [INTENTIONALLY OMITTED.]

         (c)      Pre-Closing Transfer Restrictions. Stockholder agrees not to
(i) sell, hypothecate, transfer, pledge, encumber, assign or otherwise dispose
of (including by gift) (collectively, "Transfer"), or enter into any contract,
option, put, call or other arrangement or understanding (including any profit
sharing arrangement) with respect to the Transfer of, any of the STAR Subject
Shares to any Person, other than with respect to the Margin Requirements, (ii)
trade or take any position, hedge or otherwise, with respect to the STAR
Subject Shares, (iii) enter into any voting arrangement or understanding,
whether by proxy, voting agreement or otherwise, with respect to any of the
STAR Subject Shares or (iv) take any action that would make any of its
representations or warranties contained herein untrue or incorrect or have the
effect of preventing or impeding Stockholder from performing any of his
obligations under this Agreement; provided, however, that Stockholder may,
prior to the Effective Time and subject to compliance with all applicable legal
requirements (including, without limitation, all applicable securities laws,
rules, regulations and requirements), Transfer up to 2,430,671 shares of
Stockholder's STAR Common Stock to unaffiliated third parties in one or more
arms-length transactions.

         (d)      Post-Closing Transfer Restrictions. Stockholder agrees not to
(i) Transfer, or enter into any contract, option, put, call or other
arrangement or understanding (including any profit sharing arrangement) with
respect to the Transfer of, any of the shares of WAXS Common Stock issued to
Stockholder pursuant to the Merger Agreement to any Person, or (ii) trade or
take any position, hedge or otherwise, with respect to such shares of WAXS
Common Stock, for six (6) months following the Effective Time. If, at any time
after six (6) months and within eighteen (18) months following the Effective
Time, Stockholder desires to take any action referred to in clauses (i) or (ii)
above (a "Proposed Action"), Stockholder shall give prior written notice of
such Proposed Action to WAXS, specifying the number of shares subject to the
Proposed Action. Stockholder acknowledges and agrees that WAXS shall have the
first right to assist in the private disposition of the shares specified in
such notice of Proposed Action to an "accredited investor" or "qualified
institutional buyer" (as such terms are defined in Exchange Act). If WAXS is
unable to arrange such a private disposition on terms reasonably satisfactory
to Stockholder within thirty (30) days after

                                       3

receipt of notice of the Proposed Action, Stockholder shall be free to
consummate the Proposed Action.

interests or obligations hereunder may be assigned by any party hereto without
the prior written consent of the other party hereto. Subject to the preceding
sentence, this Agreement will be binding upon, inure to the benefit of and be
enforceable by the parties hereto and their respective successors and permitted

shall become effective when one or more of the counterparts have been signed by
each of the parties and delivered to the other party, it being understood that

         (e)      Governing Law; Jurisdiction; Waiver. This Agreement shall be

<PAGE>   6

         from jurisdiction of any such court or from any legal process
         commenced in such courts (whether through service of notice,
         attachment prior to judgment, attachment in aid of execution of
         judgment, execution of judgment or otherwise), and (iv) to the fullest
         extent permitted by applicable law, that (a) the suit, action or
         proceeding in any such court is brought in an inconvenient forum, (b)
         the venue of such suit, action or proceeding is improper and (c) this
         Agreement, or the subject matter hereof, may not be enforced in or by
         such courts.

                  (f)      Severability. If any term or other provision of this
         Agreement is invalid, illegal or incapable of being enforced by any
         rule or law, or public policy, all other conditions and provisions of
         this Agreement shall nevertheless remain in full force and effect so
         long as the economic or legal substance of the transactions
         contemplated hereby is not affected in any manner materially adverse
         to any party. Upon any determination that any term or other provision
         is invalid, illegal or incapable of being enforced, the parties hereto
         shall negotiate in good faith to modify this Agreement so as to effect
         the original intent of the parties as closely as possible in an
         acceptable manner to the end that transactions contemplated hereby are
         fulfilled to the extent possible.

                  (g)      Action as Stockholder; No Limitation. Stockholder has
         agreed to the terms and conditions of this Agreement solely in his
         capacity as a holder of shares of STAR Common Stock. WAXS acknowledges
         and agrees that none of the provisions of this Agreement shall be
         deemed to limit, restrict or otherwise hinder the ability of
         Stockholder, in his capacity as a member of the Board of Directors of
         STAR, to exercise his fiduciary duties under applicable law.

         6.       Enforcement. The parties agree that irreparable damage would
occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached.
It is accordingly agreed that, in addition to any other remedy to which it may
be entitled, at law or in equity, the parties shall be entitled to the remedy
of specific performance of the covenants and agreements contained herein and
injunctive and other equitable relief.

         7.       Parties in Interest. This Agreement shall be binding upon and
inure solely to the benefit of each party hereto. Except as provided in the
preceding sentence, nothing in this Agreement, express or implied, is intended
to or shall confer upon any other person any rights, benefits or remedies or
any nature whatsoever under or by reason of this Agreement.

         (a)      Voting of STAR Subject Shares. At any meeting of stockholders
of STAR or at any adjournment thereof or in any other circumstances upon which
Stockholder's vote, consent or other approval (including by written consent) is
sought, Stockholder shall vote all of the STAR Subject Shares then beneficially
owned by Stockholder (i) in favor of the Transaction and the adoption and the
approval of the Merger Agreement and each of the other transactions contemplated
by the Merger Agreement, (ii) against any action or agreement that would result
in a breach of any covenant, representation or warranty or any other obligation
or agreement of STAR under the Merger Agreement and (iii) against any action or
agreement that would impede, interfere with, delay or postpone or that would
reasonably be expected to discourage the Transaction, including, but not limited
to: (A) any




                                       2
<PAGE>   3

extraordinary corporate transactions (other than the Transaction), such as a
merger, consolidation or other business combination involving STAR or its
Subsidiaries, a sale or transfer of a material amount of assets of STAR or its
Subsidiaries or a reorganization, recapitalization or liquidation of STAR or its
Subsidiaries; (B) any amendment of STAR's certificate of incorporation or bylaws
or other proposal or transaction involving STAR or any of its Subsidiaries,
which amendment or other proposal or transaction would in any manner impede,
prevent or nullify the Transaction, the Merger Agreement or any of the other
transactions contemplated by the Merger Agreement or change in any manner the
voting rights of any class of STAR capital stock; or (C) any change in the
management or board or directors of STAR. Stockholder shall not hereafter,
unless and until this Agreement terminates pursuant to Section 7 hereof, purport
to grant (other than through the irrevocable proxy granted in Section 2(b)) any
proxy or power of attorney with respect to any of the STAR Subject Shares,
deposit any of the STAR Subject Shares into a voting trust or enter into any
agreement (other than this Agreement), arrangement or understanding with any
Person, directly or indirectly, to vote, grant any proxy or give instructions
with respect to the voting of any of the STAR Subject Shares. Stockholder
further agrees not to commit or agree to take any action inconsistent with the
foregoing.

         (b)      Proxy. Stockholder hereby grants to and appoints WAXS and any
individual designated in writing by WAXS, as Stockholder's proxy and
attorney-in-fact (with full power of substitution), for and in the name, place
and stead of Stockholder, a proxy to vote, or to grant a consent or approval in
respect of and to represent, all of the STAR Subject Shares then beneficially
owned by Stockholder in the manner indicated in Section 2(a) above to the same
extent as Stockholder may have under applicable law, rules and regulations.
Stockholder agrees that this proxy shall be irrevocable and coupled with an
interest and may under no circumstances be revoked, agrees to take such further
action or execute such other instruments as may be necessary to effectuate the
intent of this proxy and hereby revokes any proxy previously granted by
Stockholder with respect to any of the STAR Subject Shares. Such irrevocable
proxy is executed and intended to be irrevocable in accordance with the
provisions of Section 212(e) of the DGCL.

         (c)      Pre-Closing Transfer Restrictions. Stockholder agrees that,
until the earlier of the Effective Time and the termination of this Agreement,
Stockholder will not (i) sell, hypothecate, transfer, pledge, encumber, assign
or otherwise dispose of (including by gift) (collectively, "Transfer"), or enter
into any contract, option, put, call or other arrangement or understanding
(including any profit sharing arrangement) with respect to the Transfer of, any
of the STAR Subject Shares to any Person, other than with respect to the Margin
Requirements, (ii) trade or take any position, hedge or otherwise, with respect
to the STAR Subject Shares, (iii) enter into any voting arrangement or
understanding, whether by proxy, voting agreement or otherwise, with respect to
any of the STAR Subject Shares or (iv) take any action that would make any of
its representations or warranties contained herein untrue or incorrect or have
the effect of preventing or impeding Stockholder from performing any of his
obligations under this Agreement.


                                        3

<PAGE>   4

         (d)      Post-Closing Transfer Restrictions. Stockholder agrees not to
(i) Transfer, or enter into any contract, option, put, call or other arrangement
or understanding (including any profit sharing arrangement) with respect to the
Transfer of, any of the shares of WAXS Common Stock issued to Stockholder
pursuant to the Merger Agreement to any Person, or (ii) trade or take any
position, hedge or otherwise, with respect to such shares of WAXS Common Stock,
for the longer of (x) six (6) months following the Effective Time and (y) such
time as Stockholder is a member of the Board of Directors of WAXS. If, at any
time after six (6) months and within eighteen (18) months following the
Effective Time, Stockholder desires to take any action referred to in clauses
(i) or (ii) above (a "Proposed Action"), Stockholder shall give prior written
notice of such Proposed Action to WAXS, specifying the number of shares subject
to the Proposed Action. Stockholder acknowledges and agrees that WAXS shall have
the first right to assist in the private disposition of the shares specified in
such notice of Proposed Action to an "accredited investor" or "qualified
institutional buyer" (as such terms are defined in Exchange Act). If WAXS is
unable to arrange such a private disposition on terms reasonably satisfactory to
Stockholder within thirty (30) days after receipt of notice of the Proposed
Action, Stockholder shall be free to consummate the Proposed Action.

3.       Registration Rights.

         (a)      Definitions. For purposes of this Section 3, the terms
"register", "registered" and "registration" refer to a registration effected by
preparing and filing with the Securities and Exchange Commission (the
"Commission") a registration statement or similar document in compliance with
the Securities Act of 1933, as amended (the "Securities Act"), and using
commercially reasonable efforts to obtain from the Commission the declaration or
ordering of effectiveness of such registration statement or document.

         (b)      Piggyback Registration. If at any time WAXS shall propose to
register any of its capital stock for sale or disposition (i) for its own
account for cash under the Securities Act in a public offering, other than a
registration relating to acquisitions or employee benefit plans, or (ii) for the
account of any selling stockholder, WAXS shall, to the extent permitted under
any agreements existing on the date hereof:

                  (i)      Promptly give Stockholder at least ten (10) days'
written notice prior to the filing thereof, which notice shall include the
proposed date on which the registration statement is to be filed, the proposed
price per share and a list of the jurisdictions in which WAXS intends to attempt
to qualify such securities under the applicable blue sky or other state
securities laws ("Blue Sky Laws"); and

                  (ii)     Include in such registration (and any related
qualification under Blue Sky Laws), and in any underwriting involved therein,
all of the shares of WAXS Common Stock then held by Stockholder which were
acquired pursuant to the Merger Agreement and

                                       4
<PAGE>   5

which are not publicly saleable under the Commission's Rule 144 (the "Remaining
Shares") and which are specified in a written request or requests made by
Stockholder within ten (10) days after receipt of such written notice from WAXS;
provided, however, that in no event shall Stockholder request that WAXS include
either less than twenty-five percent (25%) of such Remaining Shares or Remaining
Shares then held by Stockholder having a value of less than $2,000,000 in such
registration.

         (c)      Underwriting Agreement. The right of Stockholder to
registration pursuant to this Section 3 shall be conditioned upon Stockholder's
participation in any underwriting relating to WAXS's registered public offering.
Stockholder shall (together with WAXS) enter into an underwriting agreement in
customary form with the underwriter or underwriters selected by WAXS.
Notwithstanding any provision of this Section 3, if the managing underwriter in
its reasonable judgment determines that marketing factors require a limitation
of the number of securities to be underwritten, the underwriter may exclude some
or all of the Remaining Shares for which Stockholder seeks registration from
inclusion in the registration and underwriting; provided, however, that if WAXS
proposes to include in such registration shares of capital stock held by
shareholders of WAXS other than Stockholder ("Other Holders"), then the number
of shares to be so excluded shall be allocated among Stockholder and the Other
Holders pro rata based upon the number of shares of capital stock proposed to be
included in the registration by each of them, so long as such allocation is
consistent with any existing agreements between WAXS and a third party.

         (d)      Expenses of Registration. WAXS shall bear all registration
costs and expenses related to any registration and underwriting contemplated by
this Section 3, except that Stockholder shall bear (i) all underwriting
commissions (and transfer taxes, if any) relating to the Remaining Shares
registered and (ii) the fees and expenses of legal counsel and accountants to
Stockholder.

         (e)      Indemnification. In the event any Remaining Shares are
included in a registration statement under this Section 3:

                  (i)      To the extent permitted by law, WAXS will indemnify
and hold harmless Stockholder against any losses, claims, damages or liabilities
to which he may become subject under the Securities Act, the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), any Blue Sky Laws, or other
federal or state law, insofar as such losses, claims, damages or liabilities (or
action in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively, a "Violation"): (x) any
untrue statement or alleged untrue statement of a material fact contained in
such registration statement, including any preliminary prospectus or final
prospectus contained therein or any amendments or supplements thereto, (y) the
omission or alleged omission to state therein a material fact required to be
stated therein, or necessary to make the statements therein not misleading, or
(z) any violation or alleged violation by WAXS of the Securities Act, the
Exchange Act, any Blue Sky Laws or any rule or regulation promulgated under the

                                       5
<PAGE>   6

Securities Act, the Exchange Act or any Blue Sky Law. Notwithstanding the
preceding, WAXS shall not be liable in any such case to Stockholder for any such
loss, claim, damage, liability or action to the extent that it arises out of or
is based upon a Violation which occurs in reliance upon written information
furnished by Stockholder expressly for use in connection with such registration.

         (ii)     To the extent permitted by law, Stockholder will indemnify and
hold harmless WAXS, each of its directors, officers, agents and affiliates and
each person, if any, who controls any of the foregoing within the meaning of the
Securities Act, and any underwriter, against any losses, claims, damages or
liabilities to which WAXS or any such director, officer, controlling person, or
underwriter may become subject, under the Securities Act, the Exchange Act, any
Blue Sky Laws or other federal or state law, but only insofar as such losses,
claims, damages or liabilities (or actions in respect thereto) arise out of or
are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs solely in reliance upon and in conformity
with written information relating to the Remaining Shares furnished by
Stockholder expressly for use in connection with such registration.

         (iii)    Notwithstanding the preceding, the indemnity agreements
contained in this Section 3 shall not apply to amounts paid in settlement of any
loss, claim, damage, liability or action if such settlement is effected without
the consent of the indemnifying party, which consent shall not be unreasonably
withheld.

         (iv)     Promptly after receipt by an indemnified party under this
Section 3 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 3, deliver to
the indemnifying party a written notice of the commencement thereof. Following
receipt of such notice, the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties; provided, however,
that an indemnified party shall have the right to retain its own counsel, with
the fees and expenses to be paid by the indemnifying party, if representation of
such indemnified party by the counsel retained by the indemnifying party would
be inappropriate due to actual or potential differing interests between such
indemnified party and any other party represented by such counsel in such
proceeding. The failure to deliver written notice to the indemnifying party
within a reasonable time of the commencement of any such action shall not
relieve such indemnifying party of any liability to the indemnified party under
this Section 3 unless, and to the extent, that the indemnifying party can
demonstrate that such failure was materially prejudicial to its ability to
defend such action.

                                       6
<PAGE>   7

                           (v)      The obligations of WAXS and Stockholder
         under this Section 3 shall survive the completion of any offering of
         Remaining Shares in a registration statement under this Section 3.

                  (f)      Stockholder's Obligations. Whenever registration of
         any of Stockholder's Remaining Shares is being effected, WAXS may
         require Stockholder to furnish WAXS with the information required by
         Item 507 of Regulation S-K promulgated by the Commission (or any
         equivalent provision subsequently promulgated by the Commission),
         together with such other information as WAXS may reasonably request
         in writing.

         4.       Rule 16b-3 Approval. WAXS will cause its Board of Directors to
take any and all necessary and appropriate action under Rule 16b-3 promulgated
by the Commission in order to make the acquisition of WAXS Common Stock by
Stockholder pursuant to the Merger Agreement exempt under Section 16 of the
Exchange Act.

         5.       STAR Employees.

                  (a)      Non-Solicitation. Stockholder shall not, for one (1)
         year following the Effective Time, solicit for employment, directly or
         on behalf of any other party, any persons who (i) are employed by STAR
         (or any of its affiliates) on the date hereof or (ii) were employed by
         STAR (or any of its affiliates) during the three (3) months prior to
         the date hereof, through and including the Effective Time (such persons
         collectively being referred to as "STAR Employees"), or induce or
         attempt to induce the termination of any such person's employment with
         WAXS (or any of its affiliates).

                  (b)      Employment. For one (1) year following the Effective
         Time, without the prior written consent of WAXS (i) neither Stockholder
         nor any entity controlled by Stockholder shall hire or employ any STAR
         Employee and (ii) Stockholder shall use reasonable best efforts to
         cause any entity with which Stockholder is then affiliated not to hire
         or employ any STAR Employee.

                  (c) Exception. Paragraphs (a) and (b) above notwithstanding,
         Stockholder may solicit and employ Susan Mire at any time.

         6.       Assignment. Neither this Agreement nor any of the right,
interests or obligations hereunder may be assigned by any party hereto without
the prior written consent of the other party hereto. Subject to the preceding
sentence, this Agreement will be binding upon, inure to the benefit of and be
enforceable by the parties hereto and their respective successors and permitted
assigns.

         7.       Termination. This Agreement shall terminate, and no party
hereto shall have any rights or obligations hereunder, upon the termination of
the Merger Agreement in accordance with its terms.

                  (c)      Interpretation. When a reference is made in this
         Agreement to Sections, such reference shall be to a Section of this
         Agreement unless otherwise indicated. The headings contained in this
         Agreement are for reference purposes only and shall not affect in any
         way the meaning or interpretation of this Agreement. Wherever the words
         "include", "includes" or "including" are used in this Agreement, they
         shall be deemed to be followed by the words "without limitation".

                  (d)      Counterparts. This Agreement may be executed in one
         or more counterparts, all of which shall be considered one and the same
         agreement, and shall become effective when one or more of the
         counterparts have been signed by each of the parties and delivered to
         the other party, it being understood that each party need not sign the
         same counterpart.

                  (e)      Governing Law; Jurisdiction; Waiver. This Agreement
         shall be governed by, and construed in accordance with, the laws of the
         State of Delaware regardless of the laws that might otherwise govern
         under applicable principles of conflicts or law. Each of WAXS and
         Stockholder irrevocably agrees that any legal action or proceeding with
         respect to this Agreement or for recognition and enforcement of any
         judgment in respect hereof brought by the other party hereto or its
         successors or assigns may be brought and determined in the Chancery or
         other Courts of the State of Delaware, and each of WAXS and Stockholder
         hereby irrevocably submits with regard to any such action or proceeding
         for itself and in respect to its property, generally and
         unconditionally, to the nonexclusive jurisdiction of the aforesaid
         courts. Each of WAXS and Stockholder hereby irrevocably waives, and
         agrees not to assert, by way of motion, as a defense, counterclaim or
         otherwise, in any action or proceeding with respect to this Agreement,
         (i) any right to trial by jury with respect to any action, suit or
         proceeding arising out of or relating to this Agreement, (ii) any claim
         that it is not personally subject to the jurisdiction of the above
         named courts for any reason other than the failure to lawfully serve
         process, (iii) that it or its property is exempt or immune from
         jurisdiction of any such court or from any legal process commenced in
         such courts (whether through service of notice, attachment prior to
         judgment, attachment in aid of execution of judgment, execution of
         judgment or otherwise), and (iv) to the fullest extent permitted by
         applicable law, that (a) the suit, action or proceeding in any such
         court is brought in an inconvenient forum, (b) the venue of such suit,
         action or proceeding is improper and (c) this Agreement, or the subject
         matter hereof, may not be enforced in or by such courts.

                  (f)      Severability. If any term or other provision of this
         Agreement is invalid, illegal or incapable of being enforced by any
         rule or law, or public policy, all other conditions and provisions of
         this Agreement shall nevertheless remain in full force and effect so
         long as the economic or legal substance of the transactions
         contemplated hereby is not affected in any manner materially adverse to
         any party. Upon any determination that any term or other provision is
         invalid, illegal or incapable of being enforced, the parties hereto
         shall negotiate in good faith to modify this Agreement so as to effect
         the original intent of

                                       9
<PAGE>   10

         the parties as closely as possible in an acceptable manner to the end
         that transactions contemplated hereby are fulfilled to the extent
         possible.

                  (g)      Action as Stockholder; No Limitation.  Stockholder
         has agreed to the terms and conditions of this Agreement solely in his
         capacity as a holder of shares of STAR Common Stock. WAXS acknowledges
         and agrees that none of the provisions of this Agreement shall be
         deemed to limit, restrict or otherwise hinder the ability of
         Stockholder, in his capacity as a member of the Board of Directors of
         STAR, to exercise his fiduciary duties under applicable law.

                  (h)      Attorneys' Fees. Should any action or proceeding be
         brought to construe or enforce the terms and conditions of this
         Agreement or the rights of the parties hereunder, the losing party
         shall pay to the prevailing party all court costs and reasonable
         attorneys' fees and costs incurred in such action or proceeding.
         Attorneys' fees incurred in enforcing any judgment in respect of this
         Agreement are recoverable as a separate item. The preceding sentence is
         intended to be severable from the other provisions of this Agreement
         and to survive any judgment and, to the maximum extent permitted by
         law, shall not be deemed merged into any such judgment.

                  (i)      Enforcement. The parties agree that irreparable
         damage would occur in the event that any of the provisions of this
         Agreement were not performed in accordance with their specific terms or
         were otherwise breached. It is accordingly agreed that, in addition to
         any other remedy to which it may be entitled, at law or in equity, the
         parties shall be entitled to the remedy of specific performance of the
         covenants and agreements contained herein and injunctive and other
         equitable relief.

                  (j)      Parties in Interest. This Agreement shall be binding
         upon and inure solely to the benefit of each party hereto. Except as
         provided in the preceding sentence, nothing in this Agreement, express
         or implied, is intended to or shall confer upon any other person any
         rights, benefits or remedies or any nature whatsoever under or by
         reason of this Agreement.

                 VOTING AND STOCK TRANSFER RESTRICTION AGREEMENT


         This VOTING AND STOCK TRANSFER RESTRICTION AGREEMENT (this "Agreement),
dated as of February 11, 2000 (this "Agreement"), is made and entered into among
World Access, Inc., a Delaware corporation ("WAXS"), and Roger B. Abbott and
Rosalind Abbott (Roger B. Abbott and Rosalind Abbott are sometimes referred to
collectively herein as "Stockholder").

         WHEREAS, WAXS and Communication TeleSystems International d/b/a
WORLDxCHANGE Communications ("CTI") propose to enter into an Agreement and Plan
of Merger, dated as of the date hereof (as the same may be amended or
supplemented, the "Merger Agreement"; capitalized terms used but not defined
herein shall have the meanings set forth in the Merger Agreement), providing for
a business combination between WAXS and CTI (the "Transaction"), upon the terms
and subject to the conditions set forth in the Merger Agreement;

         WHEREAS, Roger B. Abbott and Rosalind Abbott jointly own 14,214,857
shares of CTI Common Stock (such shares of CTI Common Stock, together with any
other shares of CTI capital stock of which Stockholder acquires beneficial
ownership after the date hereof and during the term of this Agreement whether
upon the exercise of options, warrants or rights, the conversion or exchange of
convertible or exchangeable securities, or by means of purchase, dividend,
distribution or otherwise, being collectively referred to herein as the "CTI
Subject Shares"); and

         WHEREAS, as a condition to its willingness to enter in the Merger
Agreement, WAXS has requested that Stockholder enter into this Agreement;

         NOW, THEREFORE, in consideration of the premises and the
representations, warranties and agreements contained herein, the parties agree
as follows:

         1.       Representations and Warranties of Stockholder. Except as set
forth on Schedule 1 attached hereto, Stockholder hereby represents and warrants
to WAXS as follows:

                  (a)      Authority; No Conflicts. Stockholder has the legal
         capacity and all requisite power and authority to enter into this
         Agreement, to perform its obligations hereunder and to consummate the
         transactions contemplated hereby. This Agreement has been duly
         authorized, executed and delivered by Stockholder and constitutes a
         valid and binding obligation of Stockholder enforceable in accordance
         with its terms. No filing with, and no permit, authorization, consent
         or approval of, any governmental authority or any other person is
         necessary for the execution of this Agreement by Stockholder and the
         consummation by Stockholder of the transactions contemplated hereby and
         none of the execution and delivery of this Agreement by Stockholder,
         the consummation of the transactions contemplated hereby or compliance
         with the terms hereof by Stockholder will conflict with, or result in
         any violation of, or default (with or without notice or lapse of time
         or both) under any provision of any agreement to which Stockholder is a
         party, including any voting agreement, stockholders agreement, voting
         trust, trust agreement,


<PAGE>   2

         pledge agreement, loan or credit agreement, note, bond, mortgage,
         indenture, lease or other agreement, instrument, permit, concession,
         franchise or license or violate any judgment, order, notice, decree,
         statute, law, ordinance, rule or regulation applicable to Stockholder
         or to its property or assets except (i) where the failure to make such
         filings or obtain such permits, authorizations, consents or approvals
         would not prevent or delay the performance by Stockholder of its
         obligations under this Agreement or (ii) for any such conflicts,
         violations, defaults or other occurrences that would not prevent or
         delay the performance by Stockholder of its obligations under this
         Agreement.

                  (b)      CTI Subject Shares. Stockholder is the record and
         beneficial owner of, and has good and marketable title to, 14,214,857
         shares of CTI Common Stock, free and clear of any encumbrances,
         agreements, adverse claims, liens or other arrangements with respect to
         the ownership of or the right to vote or dispose of such shares of CTI
         Common Stock. Other than such shares of CTI Common Stock, Stockholder
         does not beneficially or of record own any shares of CTI capital stock
         or securities convertible or exchangeable for shares of CTI capital
         stock. Stockholder has the sole right and power to vote and dispose of
         such shares of CTI Common Stock. None of such shares of CTI Common
         Stock are subject to any voting trust or other agreement, arrangement
         or restriction with respect to the voting or transfer of any of the
         shares of CTI Common Stock, except as contemplated by this Agreement.

                  (c)      CTI Stock Options. Neither Roger B. Abbott nor
         Rosalind Abbott own any CTI Stock Options.

         2.       Covenants of Stockholder. Until the termination of this
Agreement in accordance with Section 4 hereof, Stockholder agrees as follows:

                  (a)      Voting of CTI Subject Shares. At any meeting of
         stockholders of CTI or at any adjournment thereof or in any other
         circumstances upon which Stockholder's vote, consent or other approval
         (including by written consent) is sought, Stockholder shall vote all of
         the CTI Subject Shares then beneficially owned by Stockholder (i) in
         favor of the Transaction and the adoption and approval of the Merger
         Agreement and each of the other transactions contemplated by the Merger
         Agreement and (ii) against any action or agreement that would result in
         a material breach of any covenant, representation or warranty or any
         other obligation or agreement of CTI under the Merger Agreement.
         Stockholder shall not hereafter, unless and until this Agreement
         terminates pursuant to Section 4 hereof, purport to grant any proxy or
         power of attorney with respect to any of the CTI Subject Shares,
         deposit any of the CTI Subject Shares into a voting trust or enter into
         any agreement (other than this Agreement), arrangement or understanding
         with any person, directly or indirectly, to vote, grant any proxy or
         give instructions with respect to the voting of any of the CTI Subject
         Shares. Stockholder further agrees not to commit or agree to take any
         action inconsistent with the foregoing.

                  (b)      Pre-Closing Transfer Restrictions. Except as
         contemplated by this Agreement or the Merger Agreement, Stockholder
         agrees not to (i) sell, hypothecate, transfer, pledge, encumber, assign
         or otherwise dispose of (including by gift)



                                       2

         (collectively, "Transfer"), or enter into any contract, option, put,
         call or other arrangement or understanding (including any profit
         sharing arrangement) with respect to the Transfer of, any of the CTI
         Subject Shares to any person, (ii) trade or take any position, hedge or
         otherwise, with respect to the CTI Subject Shares, (iii) enter into any
         voting arrangement or understanding, whether by proxy, voting agreement
         or otherwise, with respect to any of the CTI Subject Shares or (iv)
         take any action that would make any of its representations or
         warranties contained herein untrue or incorrect to a material extent or
         have the effect of preventing or materially impeding Stockholder from
         performing any of its obligations under this Agreement. Notwithstanding
         the foregoing, Stockholder may Transfer any of the CTI Subject Shares
         to any person who (x) is, at the time of such Transfer, already subject
         to an agreement with WAXS substantially identical in form and substance
         hereto (in which case, the CTI Subject Shares subject to the Transfer
         shall be governed by such substantially identical agreement) or (y)
         delivers to WAXS a counterpart of this Agreement duly executed by such
         person and otherwise agrees to be bound by all the terms and conditions
         hereof, and WAXS is otherwise reasonably satisfied that this Agreement
         is fully enforceable against such person; provided, however, that
         Stockholder shall not be entitled to Transfer any of the CTI Subject
         Shares unless immediately following such Transfer, the aggregate number
         of CTI Subject Shares subject to the terms and conditions hereof and/or
         to the terms and conditions of a substantially identical agreement or
         agreements with WAXS shall be at least equal to the aggregate number of
         CTI Subject Shares which are subject to the terms and conditions of
         this Agreement as of the date of the Merger Agreement.

                  (c)      Post-Closing Transfer Restrictions. Until six (6)
         months following the Effective Time, Stockholder agrees not to (i)
         Transfer or enter into any contract, option, put, call or other
         arrangement or understanding (including any profit sharing arrangement)
         with respect to the Transfer of any of the shares of WAXS Common Stock
         issued to Stockholder pursuant to the Merger Agreement to any person,
         or (ii) trade or take any position, hedge or otherwise, with respect to
         the shares of WAXS Common Stock issued to Stockholder pursuant to the
         Merger Agreement. Notwithstanding the foregoing, Stockholder shall be
         entitled to enter into one or more Qualifying Transactions (as defined
         below). If, on or prior to fifteen (15) days following the Effective
         Time (the "Sale Deadline"), (i) Stockholder shall have complied with
         its covenants set forth below in this Section 2(c), and (ii)
         Stockholder shall not have sold shares of WAXS Common Stock acquired by
         Stockholder pursuant to the Merger Agreement to a third party or third
         parties unrelated to WAXS (within the meaning of Treas. Reg. Sec. 1.368
         3(e)(3)) for a per share price equal to at least the Resale Price (as
         defined below), in one or more transactions (each, a "Qualifying
         Transaction"), and (iii) the aggregate Gross Cash Proceeds (as defined
         below) to Stockholder of all such Qualifying Transactions are less than
         $30,000,000, then Stockholder shall have the right to sell, subject to
         compliance with the provisions below in this Section 2(c), WAXS Common
         Stock which yields Gross Cash Proceeds equal to not more than the
         Unsold Amount (as defined below). Stockholder shall give WAXS written
         notice promptly after the consummation of any Qualifying Transaction.
         Stockholder shall be obligated to accept any bona fide offer for, and
         use commercially reasonable efforts to consummate on or prior to the
         Sale Deadline, one or more Qualifying Transactions which provide for a
         per share price at least equal to


                                       3
<PAGE>   4


         the Resale Price resulting in aggregate Gross Cash Proceeds to
         Stockholder of up to $30,000,000. If Stockholder shall be entitled to
         sell shares of WAXS Common Stock in respect of any Unsold Amount
         pursuant to this Section 2(c), Stockholder shall give written notice to
         WAXS so stating (and stating the number of shares of WAXS Common Stock
         that Stockholder is so entitled to sell) not less than five days prior
         to any such permitted sale of shares of WAXS Common Stock. As used
         herein, (i) the "Resale Price" equals (x) the market price of WAXS
         Common Stock as of the time a written commitment to purchase shares of
         WAXS Common Stock has been received by Stockholder (the "Commitment
         Price") or (y) a variable price equal to the market price of WAXS
         Common Stock at the time of the closing of the applicable Qualifying
         Transaction, provided that such price is between fifteen percent (15%)
         below or fifteen percent (15%) above the Commitment Price; (ii) the
         "Unsold Amount" means the difference between $30,000,000 and the Gross
         Cash Proceeds to Stockholder of all Qualifying Transactions competed
         prior to the Sale Deadline; and (iii) "Gross Cash Proceeds" means the
         gross cash proceeds to Stockholder from the consummation of any
         Qualifying Transaction hereunder, net of reasonable and customary
         expenses incurred by Stockholder in connection with such transaction
         (but not net of any taxes incurred by Stockholder in connection with
         any such Qualifying Transaction).

         3.       No Ownership Interest. Except as set forth in Section 2,
nothing contained in this Agreement shall be deemed to vest in anyone other than
Stockholder any direct or indirect ownership or incidents of ownership of or
with respect to any of the CTI Subject Shares. All rights, ownership and
economic benefits of and relating to the CTI Subject Shares shall remain and
belong to Stockholder, and no one shall have any authority to manage, direct,
restrict, regulate, govern, or administer any of the policies or operations of
CTI or exercise any power or authority to direct the voting of any of the CTI
Subject Shares as a result of this Agreement, except to the extent set forth in
Section 2(a).

         4.       Assignment. Except as otherwise specifically provided herein,
neither this Agreement nor any of the right, interests or obligations hereunder
may be assigned by any of the parties hereto without the prior written consent
of the other parties hereto.

         5.       Termination. This Agreement shall terminate, and no party
hereto shall have any rights or obligations hereunder, upon the earlier to occur
of (i) the termination of the Merger Agreement pursuant to Article IX thereof or
(ii) the lapse of the restrictions set forth in Section 2(c) hereof.

         6.       General Provisions.

                  (a)      Amendments. This Agreement may not be amended except
         by an instrument in writing signed by each of the parties hereto.

Agreement in accordance with Section 4 hereof, Stockholder agrees as follows:

                           (a)      Voting of CTI Subject Shares. At any meeting
         of stockholders of CTI or at any adjournment thereof or in any other
         circumstances upon which Stockholder's vote, consent or other approval
         (including by written consent) is sought, Stockholder shall vote all of
         the CTI Subject Shares then beneficially owned by Stockholder (i) in
         favor of the Transaction and the adoption and approval of the Merger
         Agreement and each of the other transactions contemplated by the Merger
         Agreement and (ii) against any action or agreement that would result in
         a material breach of any covenant, representation or warranty or any
         other obligation or agreement of CTI under the Merger Agreement.
         Stockholder shall not hereafter, unless and until this Agreement
         terminates pursuant to Section 5 hereof, purport to grant any proxy or
         power of attorney with respect to any of the CTI Subject Shares,

         or enter into any contract, option, put, call or other arrangement or
         understanding (including any profit sharing arrangement) with respect
         to the Transfer of, any of the CTI Subject Shares or CTI Stock Options
         to any person, (ii) trade or take any position, hedge or otherwise,

<PAGE>   3


         any voting arrangement or understanding, whether by proxy, voting
         agreement or otherwise, with respect to any of the CTI Subject Shares
         or (iv) take any action that would make any of its representations or
         warranties contained herein untrue or incorrect to a material extent or
         have the effect of preventing or materially impeding Stockholder from
         performing any of its obligations under this Agreement. Notwithstanding
         the foregoing, Stockholder may Transfer any of the CTI Subject Shares
         or CTI Stock Options to any person who (x) is, at the time of such
         Transfer, already subject to an agreement with WAXS substantially
         identical in form and substance hereto (in which case, the CTI Subject
         Shares or CTI Stock Options subject to the Transfer shall be governed
         by such substantially identical agreement) or (y) delivers to WAXS a
         counterpart of this Agreement duly executed by such person and
         otherwise agrees to be bound by all the terms and conditions hereof,
         and WAXS is otherwise reasonably satisfied that this Agreement is fully
         enforceable against such person; provided, however, that Stockholder
         shall not be entitled to Transfer any of the CTI Subject Shares or CTI
         Stock Options unless immediately following such Transfer, the aggregate
         number of CTI Subject Shares and CTI Stock Options subject to the terms
         and conditions hereof and to the terms and conditions of other
         agreements with WAXS substantially similar in form and substance hereto
         shall be at least equal to the aggregate number of CTI Subject Shares
         and CTI Stock Options which are subject to the terms and conditions of
         such agreements as of the date of the Merger Agreement.

                           (c)      Post-Closing Transfer Restrictions. Until
         six (6) months after the Effective Time, Stockholder agrees not to (i)
         Transfer or enter into any contract, option, put, call or other
         arrangement or understanding (including any profit sharing arrangement)
         with respect to the Transfer of any of the shares of WAXS Common Stock
         issued to Stockholder pursuant to the Merger Agreement to any person,
         or (ii) trade or take any position, hedge or otherwise, with respect to
         the shares of WAXS Common Stock issued to Stockholder pursuant to the
         Merger Agreement.

         3.       No Ownership Interest. Except as set forth in Section 2,

may be assigned by any of the parties hereto without the prior written consent
of the other parties hereto.

         5.       Termination. This Agreement shall terminate, and no party

         Stockholder of its obligations under this Agreement.

                  (b)      CTI Subject Shares. Stockholder is the record and
         beneficial owner of, and has good and marketable title to, 4,505,043
         shares of CTI Common Stock, 30,000 shares of CTI Series A Preferred
         Stock and 37,500 shares of CTI Series B Preferred Stock, free and clear
         of any encumbrances, agreements, adverse claims, liens or other
         arrangements with respect to the ownership of or the right to vote or
         dispose of such shares of CTI Capital Stock. Other than such shares of
         CTI Capital Stock, Stockholder does not beneficially or of record own
         any shares of CTI capital stock or securities convertible or
         exchangeable for shares of CTI capital stock. Stockholder has the sole
         right and power to vote and dispose of such shares of CTI Capital
         Stock. None of such shares of CTI Capital Stock are subject to any
         voting trust or other agreement, arrangement or restriction with
         respect to the voting or transfer of any of the shares of CTI Capital
         Stock, except as contemplated by this Agreement.

                  (c)      CTI Stock Options. Stockholder owns CTI Stock Options
         to acquire 170,000 shares of CTI Common Stock. Other than such CTI
         Stock Options, Stockholder has no options, warrants or other rights to
         acquire shares of CTI capital stock or securities convertible into
         shares of CTI capital stock.

         2.       Covenants of Stockholder. Until the termination of this
Agreement in accordance with Section 4 hereof, Stockholder agrees as follows:

                  (a)      Voting of CTI Subject Shares. At any meeting of
         stockholders of CTI or at any adjournment thereof or in any other
         circumstances upon which Stockholder's vote, consent or other approval
         (including by written consent) is sought, Stockholder shall vote all of
         the CTI Subject Shares then beneficially owned by Stockholder (i) in
         favor of the Transaction and the adoption and approval of the Merger
         Agreement and each of the other transactions contemplated by the Merger
         Agreement and (ii) against any action or agreement that would result in
         a material breach of any covenant, representation or warranty or any
         other obligation or agreement of CTI under the Merger Agreement.
         Stockholder shall not hereafter, unless and until this Agreement
         terminates pursuant to Section 4 hereof, purport to grant any proxy or
         power of attorney with respect to any of the CTI Subject Shares,
         deposit any of the CTI Subject Shares into a voting trust or enter into
         any agreement (other than this Agreement), arrangement or understanding
         with any person, directly or indirectly, to vote, grant any proxy or
         give instructions with respect to

                                       2
<PAGE>   3



         the voting of any of the CTI Subject Shares. Stockholder further agrees
         not to commit or agree to take any action inconsistent with the
         foregoing.

                  (b)      Pre-Closing Transfer Restrictions. Except as
         contemplated by this Agreement or the Merger Agreement, Stockholder
         agrees not to (i) sell, hypothecate, transfer, pledge, encumber, assign
         or otherwise dispose of (including by gift) (collectively, "Transfer"),
         or enter into any contract, option, put, call or other arrangement or
         understanding (including any profit sharing arrangement) with respect
         to the Transfer of, any of the CTI Subject Shares or CTI Stock Options
         to any person, (ii) trade or take any position, hedge or otherwise,
         with respect to the CTI Subject Shares, (iii) enter into any voting
         arrangement or understanding, whether by proxy, voting agreement or
         otherwise, with respect to any of the CTI Subject Shares or (iv) take
         any action that would make any of its representations or warranties
         contained herein untrue or incorrect to a material extent or have the
         effect of preventing or materially impeding Stockholder from performing
         any of its obligations under this Agreement. Notwithstanding the
         foregoing, Stockholder may Transfer any of CTI Subject Shares or CTI
         Stock Options to any person who (x) is, at the time of such Transfer,
         already subject to an agreement with WAXS substantially identical in
         form and substance hereto (in which case, the CTI Subject Shares or CTI
         Stock Options subject to the Transfer shall be governed by such
         substantially identical agreement) or (y) delivers to WAXS a
         counterpart of this Agreement duly executed by such person and
         otherwise agrees to be bound by all the terms and conditions hereof,
         and WAXS is otherwise reasonably satisfied that this Agreement is fully
         enforceable against such person; provided, however, that Stockholder
         shall not be entitled to Transfer any of the CTI Subject Shares or CTI
         Stock Options unless immediately following such Transfer, the aggregate
         number of CTI Subject Shares and CTI Stock Options subject to the terms
         and conditions hereof and/or to the terms and conditions of a
         substantially identical agreement or agreements with WAXS shall be at
         least equal to the aggregate number of CTI Subject Shares and CTI Stock
         Options which are subject to the terms and conditions of this Agreement
         as of the date of the Merger Agreement.

                  (c)      Post-Closing Transfer Restrictions. Until six (6)
         months following the Effective Time, Stockholder agrees not to (i)
         Transfer or enter into any contract, option, put, call or other
         arrangement or understanding (including any profit sharing arrangement)
         with respect to the Transfer of any of the shares of WAXS Common Stock
         issued to Stockholder pursuant to the Merger Agreement to any person,
         or (ii) trade or take any position, hedge or otherwise, with respect to
         the shares of WAXS Common Stock issued to Stockholder pursuant to the
         Merger Agreement.

         3.       No Ownership Interest. Except as set forth in Section 2,
nothing contained in this Agreement shall be deemed to vest in anyone other than
Stockholder any direct or indirect ownership or incidents of ownership of or
with respect to any of the CTI Subject Shares or the CTI Stock Options. All
rights, ownership and economic benefits of and relating to the CTI Subject
Shares and the CTI Stock Options shall remain and belong to Stockholder, and no
one shall have any authority to manage, direct, restrict, regulate, govern, or
administer any of the


                                       3
<PAGE>   4


policies or operations of CTI or exercise any power or authority to direct the
voting of any of the CTI Subject Shares as a result of this Agreement, except to
the extent set forth in Section 2(a).

         4.       Assignment. Except as otherwise specifically provided herein,
neither this Agreement nor any of the right, interests or obligations hereunder
may be assigned by any of the parties hereto without the prior written consent
of the other parties hereto.

         5.       Termination. This Agreement shall terminate, and no party
hereto shall have any rights or obligations hereunder, upon the earlier to occur
of (i) the termination of the Merger Agreement pursuant to Article IX thereof or
(ii) the lapse of the restrictions set forth in Section 2(c) hereof.

         6.       Conversion of Preferred Stock. Stockholder acknowledges and
agrees that any accrued and unpaid dividends owed to Stockholder in respect of
its shares of CTI Preferred Stock in connection with the automatic conversion of
such CTI Preferred Stock under the articles of incorporation of CTI upon
consummation of the Merger shall be paid solely in shares of WAXS Common Stock
(valued at $20.38 per share).

         7.       General Provisions.

                  (a)      Amendments. This Agreement may not be amended except

         conditions and provisions of this Agreement shall nevertheless remain
         in full force and effect so long as the economic or legal substance of
         the transactions contemplated hereby is not affected in any manner
         materially adverse to any party. Upon any determination that any term
         or other provision is invalid, illegal or incapable of being enforced,

specific performance of the covenants and agreements contained herein and
injunctive and other equitable relief.

to or shall confer upon any other person any rights, benefits or remedies or any
nature whatsoever under or by reason of this Agreement.

                VOTING AND STOCK TRANSFER RESTRICTION AGREEMENT


         This VOTING AND STOCK TRANSFER RESTRICTION AGREEMENT (this
"Agreement"), dated as of February 11, 2000 (this "Agreement"), is made and
entered into among World Access, Inc., a Delaware corporation ("WAXS"), and

         WHEREAS, WAXS and Communication TeleSystems International d/b/a
WORLDxCHANGE Communications ("CTI") propose to enter into an Agreement and Plan
of Merger, dated as of the date hereof (as the same may be amended or
supplemented, the "Merger Agreement"; capitalized terms used but not defined

         WHEREAS, Stockholder owns 7,331,812 shares of CTI Common Stock, (such
shares of CTI Common Stock, together with any other shares of CTI capital stock
of which Stockholder acquires beneficial ownership after the date hereof and
during the term of this Agreement whether upon the exercise of options,

collectively referred to herein as the "CTI Subject Shares"); and

         WHEREAS, as a condition to its willingness to enter in the Merger
Agreement, WAXS has requested that Stockholder enter into this Agreement;

         NOW, THEREFORE, in consideration of the premises and the
representations, warranties and agreements contained herein, the parties agree
as follows:

         1. Representations and Warranties of Stockholder. Except as set forth
on Schedule 1 attached hereto, Stockholder hereby represents and warrants to
WAXS as follows:

                  (a) Authority; No Conflicts. Stockholder has the legal
         capacity and all requisite power and authority to enter into this
         Agreement, to perform its obligations hereunder and to consummate the
         transactions contemplated hereby. This Agreement has been duly
         authorized, executed and delivered by Stockholder and constitutes a
         valid and binding obligation of Stockholder enforceable in accordance
         with its terms. No filing with, and no permit, authorization, consent
         or approval of, any governmental authority or any other person is
         necessary for the execution of this Agreement by Stockholder and the
         consummation by Stockholder of the transactions contemplated hereby
         and none of the execution and delivery of this Agreement by
         Stockholder, the consummation of the transactions contemplated hereby
         or compliance with the terms hereof by Stockholder will conflict with,
         or result in any violation of, or default (with or without notice or
         lapse of time or both) under any provision of any agreement to which
         Stockholder is a party, including any voting agreement, stockholders
         agreement, voting trust, trust agreement, pledge agreement, loan or
         credit agreement, note, bond, mortgage, indenture, lease or other
         agreement, instrument, permit, concession, franchise or license or
         violate any


<PAGE>   2


         judgment, order, notice, decree, statute, law, ordinance, rule or
         regulation applicable to Stockholder or to its property or assets
         except (i) where the failure to make such filings or obtain such
         permits, authorizations, consents or approvals would not prevent or
         delay the performance by Stockholder of its obligations under this
         Agreement or (ii) for any such conflicts, violations, defaults or
         other occurrences that would not prevent or delay the performance by
         Stockholder of its obligations under this Agreement.

                  (b) CTI Subject Shares. Stockholder is the record and
         beneficial owner of, and has good and marketable title to, 7,331,812
         shares of CTI Common Stock, free and clear of any encumbrances,
         agreements, adverse claims, liens or other arrangements with respect
         to the ownership of or the right to vote or dispose of such shares of
         CTI Common Stock. Other than such shares of CTI Common Stock,
         Stockholder does not beneficially or of record own any shares of CTI
         capital stock or securities convertible or exchangeable for shares of
         CTI capital stock. Stockholder has the sole right and power to vote
         and dispose of such shares of CTI Common Stock. None of such shares of
         CTI Common Stock are subject to any voting trust or other agreement,
         arrangement or restriction with respect to the voting or transfer of
         any of the shares of CTI Common Stock, except as contemplated by this
         Agreement.

                  (c) CTI Stock Options. Stockholder does not own any CTI Stock
         Options.

         2. Covenants of Stockholder. Until the termination of this Agreement
in accordance with Section 4 hereof, Stockholder agrees as follows:

                  (a) Voting of CTI Subject Shares. At any meeting of
         stockholders of CTI or at any adjournment thereof or in any other
         circumstances upon which Stockholder's vote, consent or other approval
         (including by written consent) is sought, Stockholder shall vote all
         of the CTI Subject Shares then beneficially owned by Stockholder (i)
         in favor of the Transaction and the adoption and approval of the
         Merger Agreement and each of the other transactions contemplated by
         the Merger Agreement and (ii) against any action or agreement that
         would result in a material breach of any covenant, representation or
         warranty or any other obligation or agreement of CTI under the Merger
         Agreement. Stockholder shall not hereafter, unless and until this
         Agreement terminates pursuant to Section 4 hereof, purport to grant
         any proxy or power of attorney with respect to any of the CTI Subject
         Shares, deposit any of the CTI Subject Shares into a voting trust or
         enter into any agreement (other than this Agreement), arrangement or
         understanding with any person, directly or indirectly, to vote, grant
         any proxy or give instructions with respect to the voting of any of
         the CTI Subject Shares. Stockholder further agrees not to commit or
         agree to take any action inconsistent with the foregoing.


                  (b) Pre-Closing Transfer Restrictions. Except as contemplated
         by this Agreement or the Merger Agreement, Stockholder agrees not to
         (i) sell, hypothecate, transfer, pledge, encumber, assign or otherwise
         dispose of (including by gift) (collectively, "Transfer"), or enter
         into any contract, option, put, call or other arrangement or
         understanding (including any profit sharing arrangement) with respect
         to the Transfer


                                       2

         of, any of the CTI Subject Shares to any person, (ii) trade or take
         any position, hedge or otherwise, with respect to the CTI Subject
         Shares, (iii) enter into any voting arrangement or understanding,
         whether by proxy, voting agreement or otherwise, with respect to any
         of the CTI Subject Shares or (iv) take any action that would make any
         of its representations or warranties contained herein untrue or
         incorrect to a material extent or have the effect of preventing or
         materially impeding Stockholder from performing any of its obligations
         under this Agreement. Notwithstanding the foregoing, Stockholder may
         Transfer any of the CTI Subject Shares to any person who (x) is, at
         the time of such Transfer, already subject to an agreement with WAXS
         substantially identical in form and substance hereto (in which case,
         the CTI Subject Shares subject to the Transfer shall be governed by
         such substantially identical agreement) or (y) delivers to WAXS a
         counterpart of this Agreement duly executed by such person and
         otherwise agrees to be bound by all the terms and conditions hereof,
         and WAXS is otherwise reasonably satisfied that this Agreement is
         fully enforceable against such person; provided, however, that
         Stockholder shall not be entitled to Transfer any of the CTI Subject
         Shares unless immediately following such Transfer, the aggregate
         number of CTI Subject Shares subject to the terms and conditions
         hereof and/or to the terms and conditions of a substantially identical
         agreement or agreements with WAXS shall be at least equal to the
         aggregate number of CTI Subject Shares which are subject to the terms
         and conditions of this Agreement as of the date of the Merger
         Agreement.

                  (c) Post-Closing Transfer Restrictions. Until six (6) months
         following the Effective Time, Stockholder agrees not to (i) Transfer
         or enter into any contract, option, put, call or other arrangement or
         understanding (including any profit sharing arrangement) with respect
         to the Transfer of any of the shares of WAXS Common Stock issued to
         Stockholder pursuant to the Merger Agreement to any person, or (ii)
         trade or take any position, hedge or otherwise, with respect to the
         shares of WAXS Common Stock issued to Stockholder pursuant to the
         Merger Agreement. Notwithstanding the foregoing, at any time following
         the Effective Time, Stockholder shall be permitted to Transfer, in
         accordance with applicable laws, up to 750,000 shares of the WAXS
         Common Stock issued to Stockholder pursuant to the Merger Agreement.

         3. No Ownership Interest. Except as set forth in Section 2, nothing
contained in this Agreement shall be deemed to vest in anyone other than
Stockholder any direct or indirect ownership or incidents of ownership of or
with respect to any of the CTI Subject Shares. All rights, ownership and
economic benefits of and relating to the CTI Subject Shares shall remain and
belong to Stockholder, and no one shall have any authority to manage, direct,
restrict, regulate, govern, or administer any of the policies or operations of
CTI or exercise any power or authority to direct the voting of any of the CTI
Subject Shares as a result of this Agreement, except to the extent set forth in
Section 2(a).

         4. Assignment. Except as otherwise specifically provided herein,
neither this Agreement nor any of the right, interests or obligations hereunder
may be assigned by any of the parties hereto without the prior written consent

                  (c) Interpretation. When a reference is made in this
         Agreement to Sections, such reference shall be to a Section of this
         Agreement unless otherwise indicated. The headings contained in this
         Agreement are for reference purposes only and shall not affect in any
         way the meaning or interpretation of this Agreement. Wherever the

         Agreement is invalid, illegal or incapable of being enforced by any
         rule or law, or public policy, all other conditions and provisions of
         this Agreement shall nevertheless remain in full force and effect so
         long as the economic or legal substance of the transactions
         contemplated hereby is not affected in any manner materially adverse
         to any party. Upon any determination that any term or other provision
         is invalid, illegal or incapable of being enforced, the parties hereto
         shall negotiate in good faith to modify this Agreement so as to effect

                 VOTING AND STOCK TRANSFER RESTRICTION AGREEMENT


         This VOTING AND STOCK TRANSFER RESTRICTION AGREEMENT, dated as of

Communication TeleSystems International d/b/a WORLDxCHANGE Communications, a
California corporation ("CTI"), and the parties listed on Exhibit A attached

         WHEREAS, World Access, Inc., a Delaware corporation ("WAXS"), and CTI
propose to enter into an Agreement and Plan of Merger, dated as of the date

number of shares of WAXS Common Stock or other capital stock of WAXS (such
shares of WAXS Common Stock and other capital stock of WAXS being referred to as

         WHEREAS, as a condition to its willingness to enter in the Merger
Agreement, CTI has requested that the WAXS Stockholders enter into this
Agreement.

         NOW, THEREFORE, in consideration of the premises and the
representations, warranties and agreements contained herein, the parties agree
as follows:

         1.       Representations and Warranties of the WAXS Stockholders.
Except as set forth on Exhibit A attached hereto, each WAXS Stockholder hereby
represents and warrants to CTI as to itself as follows:

                  (a)      Authority; No Conflicts. Such WAXS Stockholder has
         the legal capacity and all requisite power and authority to enter into
         this Agreement, to perform its obligations hereunder and to consummate
         the transactions contemplated hereby. This Agreement has been duly
         authorized, executed and delivered by such WAXS Stockholder and
         constitutes a valid and binding obligation of such WAXS Stockholder
         enforceable in accordance with its terms. No filing with, and no
         permit, authorization, consent or approval of, any governmental
         authority or any other person is necessary for the execution of this
         Agreement by such WAXS Stockholder and the consummation by such WAXS
         Stockholder of the transactions contemplated hereby and none of the
         execution and delivery of this Agreement by such WAXS Stockholder, the
         consummation of the


<PAGE>   2
         transactions contemplated hereby or compliance with the terms hereof by
         such WAXS Stockholder will conflict with, or result in any violation
         of, or default (with or without notice or lapse of time or both) under
         any provision of, as applicable, the certificate of incorporation,
         bylaws or analogous documents of such WAXS Stockholder or any agreement
         to which such WAXS Stockholder is a party, including any voting
         agreement, stockholders agreement, voting trust, trust agreement,
         pledge agreement, loan or credit agreement, note, bond, mortgage,
         indenture, lease or other agreement, instrument, permit, concession,
         franchise or license or violate any judgment, order, notice, decree,
         statute, law, ordinance, rule or regulation applicable to such WAXS
         Stockholder or to its property or assets except (i) where the failure
         to make such filings or obtain such permits, authorizations, consents
         or approvals would not prevent or delay the performance by such WAXS
         Stockholder of its obligations under this Agreement or (ii) for any
         such conflicts, violations, defaults or other occurrences that would
         not prevent or delay the performance by such WAXS Stockholder of its
         obligations under this Agreement.

                  (b)      Subject Shares. Except as set forth on Exhibit A
         hereto, such WAXS Stockholder is the record and beneficial owner of
         (or, in the case of John D. Phillips, has sole direct or indirect
         voting and dispositive power over), and has good and marketable title
         to, the number of Subject Shares set forth opposite such WAXS
         Stockholder's name on Exhibit A hereto, free and clear of any
         encumbrances, agreements, adverse claims, liens or other arrangements
         with respect to the ownership of or the right to vote or dispose of
         such Subject Shares. Other than such Subject Shares, such WAXS
         Stockholder does not beneficially or of record own any shares of WAXS
         Capital Stock or securities convertible into or exchangeable for shares
         of WAXS Capital Stock. Except as set forth on Exhibit A hereto, such
         WAXS Stockholder has the sole right and power to vote and dispose of
         such Subject Shares. Except as set forth on Exhibit A hereto, none of
         such Subject Shares are subject to any voting trust or other agreement,
         arrangement or restriction with respect to the voting or transfer of
         any of the Subject Shares, except as contemplated by this Agreement.

         2.       Voting and Transfer of Subject Shares.

                  (a)      Until the termination of this Agreement in accordance
         with Section 5 hereof, each WAXS Stockholder agrees as to itself that
         at any meeting of stockholders of WAXS or at any adjournment thereof or
         in any other circumstance upon which the WAXS Stockholders' vote,
         consent or other approval (including by written consent) is sought,
         such WAXS Stockholder shall vote all of the Subject Shares then
         beneficially owned by such WAXS Stockholder (i) in favor of the
         Transaction and the adoption and the approval of the Merger Agreement
         and each of the other transactions contemplated by the Merger Agreement
         and (ii) against any action or agreement that would result in a
         material breach of any covenant, representation or warranty or any
         other obligation or agreement of WAXS under the Merger Agreement. No
         WAXS Stockholder shall hereafter, unless and until this Agreement
         terminates pursuant to Section 5 hereof, purport to grant any proxy or
         power of attorney with respect to any of the Subject Shares set forth
         opposite such WAXS Stockholder's name on Exhibit A, deposit any of such
         Subject Shares into a voting trust or enter into any agreement (other
         than this


                                       2
<PAGE>   3
         Agreement), arrangement or understanding with any person, directly or
         indirectly, to vote, grant any proxy or give instructions with respect
         to the voting of any of such Subject Shares, in each case only to the
         extent it relates to the matters referred to in the first sentence of
         this Section 2(a). Each WAXS Stockholder further agrees not to commit
         or agree to take any action inconsistent with the foregoing.

                  (b)      Prior to the termination of this Agreement in
         accordance with Section 5 hereof, each WAXS Stockholder agrees not to
         sell, hypothecate, transfer, pledge, encumber, assign or otherwise
         dispose of (including by gift) (collectively, "Transfer") any of the
         Subject Shares or WAXS Stock Options held by such WAXS Stockholder
         (beneficially or of record) except Transfers pursuant to bona fide
         transactions with unaffiliated persons or entities.

         3.       No Ownership Interest. Except as set forth in Section 2,
nothing contained in this Agreement shall be deemed to vest in anyone other than
the WAXS Stockholders any direct or indirect ownership or incidents of ownership
of or with respect to any of the Subject Shares or WAXS Stock Options. All
rights, ownership and economic benefits of and relating to the Subject Shares
and the WAXS Stock Options shall remain and belong to the WAXS Stockholders, and
no one shall have any authority to manage, direct, restrict, govern or
administer any of the policies or operations of WAXS or exercise any power or
authority to direct the voting of any of the Subject Shares as a result of this
Agreement, except to the extent set forth in Section 2(a).

         4.       Assignment. Except as otherwise specifically provided herein,
neither this Agreement nor any of the rights, interests or obligations hereunder
may be assigned by any of the parties hereto without the prior written consent
of the other parties hereto.

         5.       Termination. This Agreement shall terminate, and no party
hereto shall have any rights or obligations hereunder, upon the first to occur
of (i) the termination of the Merger Agreement pursuant to Article IX thereof,
(ii) the Effective Time and (iii) October 31, 2000.

         6.       General Provisions.

                  (a)      Amendments. This Agreement may not be amended except
         by an instrument in writing signed by each of the parties hereto.

                  (b)      Notices. All notices, requests, claims, demands and
         other communications hereunder shall be in writing and shall be given
         (and shall be deemed to have been duly given upon receipt) by delivery

                  (c)      Interpretation. When a reference is made in this
         Agreement to Sections, such reference shall be to a Section of this
         Agreement unless otherwise indicated. The headings contained in this
         Agreement are for reference purposes only and shall not affect in any
         way the meaning or interpretation of this Agreement. Wherever the words

                  (d)      Counterparts. This Agreement may be executed in two
         or more counterparts, all of which shall be considered one and the same
         agreement, and shall become effective when one or more of the
         counterparts have been signed by each of the parties and delivered to
         the other party, it being understood that each party need not sign the
         same counterpart.

         principles of conflicts or law.

                  (f)      Severability. If any term or other provision of this
         Agreement is invalid, illegal or incapable of being enforced by any
         rule or law, or public policy, all other conditions and provisions of
         this Agreement shall nevertheless remain in full force and effect so
         long as the economic or legal substance of the transactions
         contemplated hereby

         is not affected in any manner materially adverse to any party. Upon any
         determination that any term or other provision is invalid, illegal or
         incapable of being enforced, the parties hereto shall negotiate in good
         faith to modify this Agreement so as to effect the original intent of
         the parties as closely as possible in an acceptable manner to the end
         that transactions contemplated hereby are fulfilled to the extent
         possible.

         7.       Enforcement. The parties agree that irreparable damage would
occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed that, in addition to any other remedy to which it may be
entitled, at law or in equity, the parties shall be entitled to the remedy of
specific performance of the covenants and agreements contained herein and
injunctive and other equitable relief.

         8.       Parties in Interest. This Agreement shall be binding upon and
inure solely to the benefit of each party hereto. Except as provided in the
preceding sentence, nothing in this Agreement, express or implied, is intended
to or shall confer upon any other person any rights, benefits or remedies or any
nature whatsoever under or by reason of this Agreement.

                                ESCROW AGREEMENT


         THIS ESCROW AGREEMENT (this "Agreement") is made and entered into as
of the ___ day of _______, 2000, by and among World Access, Inc., a Delaware
corporation ("WAXS"), Edward S. Soren (the "Shareholder Representative") and
SunTrust Bank, Atlanta, a Georgia banking corporation (the "Escrow Agent").

                              W I T N E S S E T H:

         WHEREAS, WAXS and Communications TeleSystems International d/b/a
WORLDxCHANGE Communications ("CTI") are parties to an Agreement and Plan of
Merger, dated February __, 2000 (the "Merger Agreement"), pursuant to which
WAXS has agreed to acquire CTI on the terms and conditions set forth in the
Merger Agreement;

         WHEREAS, the Merger Agreement provides for the establishment of an
escrow to secure the indemnification obligations under the Merger Agreement of
the shareholders of CTI listed on Schedule 1 hereto (the "CTI Shareholders");

         WHEREAS, the Shareholder Representative has been appointed the
representative and agent of the CTI Shareholders for purposes of actions and
decisions required or permitted to be taken or made by the CTI Shareholders
under the Merger Agreement or this Agreement;

         WHEREAS, it is the intent of the parties hereto that the CTI
Shareholders be considered the beneficial owners of both the shares of WAXS
Common Stock constituting the Escrow Fund (as defined below) as well as the
Contingent Shares, if any, held by the Escrow Agent hereunder and which are not
part of the Escrow Fund, for income tax purposes, including, without
limitation, under Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"), so that both the shares of WAXS Common Stock as well as
the Contingent Shares, if any, will be treated as having been received by the
CTI Shareholders at the time set forth in the Merger Agreement for Section
368(a) purposes; and

         WHEREAS, capitalized terms used but not otherwise defined herein shall
have the meanings given to them in the Merger Agreement.

         NOW, THEREFORE, for and 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 hereto do hereby
mutually agree as follows:


<PAGE>   2


         1.       Escrow of Security.

                  (a) As security for the indemnification obligations of the
CTI Shareholders under the Merger Agreement, 2,453,385 shares of WAXS Common
Stock (the "Escrow Fund") have been delivered to the Escrow Agent, which shares
shall be held and released by the Escrow Agent in accordance with the terms
hereof.

                  (b) If any Contingent Shares are issued at a time that shares
of WAXS Common Stock remain in escrow pursuant hereto, then any Contingent
Shares that are issued with respect to such shares of WAXS Common Stock held
hereunder shall be delivered to the Escrow Agent and shall be held and released
in accordance with the terms of Section 4 hereof.

         2.       Loss Incurred.

                  (a) In the event that WAXS claims to have suffered a Loss for
which it believes it is entitled to indemnification pursuant to Article VIII of
the Merger Agreement, it shall notify the Escrow Agent and the Shareholder
Representative in a writing providing the information required pursuant to
Section 8.4 of the Merger Agreement (a "Notice of Loss").

                  (b) Within twenty (20) days following delivery of a Notice of
Loss, the Shareholder Representative shall provide to WAXS, with a copy to the
Escrow Agent, a written response (a "Response Letter") in which the Shareholder
Representative shall (i) agree that all of the amounts claims as a Loss in such
Notice of Loss may be released from the Escrow Fund, (ii) agree that part, but
not all, of the amounts claimed as a Loss in such Notice of Loss may be
released from the Escrow Fund to WAXS or (iii) dispute that any of the amounts
claimed as a Loss in such Notice of Loss may be released from the Escrow Fund
to WAXS. If no Response Letter is delivered by the Shareholder Representative
within such 20-day period, the Shareholder Representative shall be deemed to
have disputed that any of the amounts claimed as a Loss in such Notice of Loss
may be released from the Escrow Fund to WAXS.

                  (c) If the Shareholder Representative agrees that all or part
of the amounts claimed as a Loss in such Notice of Loss may be released from
the Escrow Fund to WAXS (the "Agreed Amount"), the Escrow Agent shall release
to WAXS from the Escrow Fund an amount of shares of WAXS Common Stock equal to
the Agreed Amount.

                  (d) In the event that the Shareholder Representative disputes
(or is deemed to have disputed) the claim by WAXS of a Loss pursuant to Section
2(b) above, the Escrow Agent shall not pay the disputed amount of such claim to
WAXS except as it may be directed (A) by a final decision of a court of
competent jurisdiction, which decision has not been appealed within any
applicable time periods for such appeal or with respect to which no appeal is
available, or (B) by a notice in writing signed by WAXS and the Shareholder
Representative. Such disputed claims of a Loss are hereinafter referred to as
"Disputed Unpaid Losses." For purposes hereof, Disputed Unpaid Losses will be
deemed to have been resolved upon the Escrow Agent paying


                                       2
<PAGE>   3


the claim of Loss in accordance with clauses (A) or (B) above or upon a
determination that WAXS is not entitled to be paid by the Escrow Agent any
amount claimed as a Loss contained (X) in a final decision of a court of
competent jurisdiction, which decision has not been appealed within any
applicable time periods for such appeal or with respect to which no appeal is
available, or (Y) in a notice in writing signed by WAXS and the Shareholder
Representative.

         3.       Release of Funds. In the event that on the first (1st)
anniversary of the Closing Date no Notice of Loss is pending, the Escrow Agent
shall release for transfer to the CTI Shareholders their pro rata portion of
the balance of the Escrow Fund, if any. If on such date one or more Notices of
Loss are pending, the Escrow Agent shall retain in escrow, from such amount to
be released pursuant to this Section 3, such number of shares of WAXS Common
Stock from the Escrow Fund as shall be sufficient to satisfy the amount of the
Loss(es) specified in such Notice(s) of Loss, and release for transfer to the
CTI Shareholders their pro rata portion of the remaining balance, if positive.
Upon resolution of all Disputed Unpaid Losses, the Escrow Agent shall release
to the CTI Shareholders their pro rata portion of the balance, if any, of the
Escrow Fund.

         4.       Valuation of Escrow Fund; Release of Contingent Shares.

                  (a) For purposes of this Agreement, including, without
limitation, the satisfaction of any claims pursuant to Section 2 hereof, the
value of each share of WAXS Common Stock constituting a part of the Escrow Fund
shall equal $20.38.

                  (b) The Contingent Shares, if any, that are delivered to the
Escrow Agent pursuant to Section 1(b) hereof shall not constitute a part of the
Escrow Fund. Each Contingent Share shall be released at such time as, and to
the party entitled to receive, the underlying share of WAXS Common Stock with
respect to which such Contingent Share was issued pursuant to the Merger
Agreement is released pursuant to Section 3.

         5.       Voting Rights; Dividends. The CTI Shareholders shall be the
holders of record with full voting rights to both the shares of WAXS Common
Stock as well as the Contingent Shares, if any, described in Section 1(b)
hereof and held by the Escrow Agent hereunder and which are not part of the
Escrow Fund. The CTI Shareholders shall be entitled to exercise such voting
rights until such time, if any, as such shares of WAXS Common Stock are
forfeited to WAXS in payment of a Loss pursuant to Section 2 hereof. The Escrow
Agent shall deliver to the CTI Shareholders such proxies or other documents as
may be necessary to enable the CTI Shareholders to exercise such voting rights.
Further, the CTI Shareholders shall be entitled to promptly receive any
distribution with respect to the shares of WAXS Common Stock and Contingent
Shares including, without limitation, any distribution which constitutes a
"dividend" within the meaning of Section 316 of the Code. Any such
distributions paid with respect to such shares shall be distributed by the
Escrow Agent to the CTI Shareholders as the holders of record of such shares.

         6.       Rights and Obligations of the Escrow Agent.

                  (a) In performing any of its duties under this Agreement, or
upon the claimed failure to perform its duties hereunder, the Escrow Agent
shall not be liable to anyone for any damages, losses, or expenses which they
may incur as a result of the Escrow Agent so acting, or failing to act;
provided, however, that the Escrow Agent shall be liable for damages arising
out of its willful misconduct or gross negligence under this Agreement.
Accordingly, the Escrow Agent shall not incur any such liability with respect
to (i) any action taken or omitted to be taken in good faith upon advice of its
counsel given with respect to any questions relating to the duties and
responsibilities of the Escrow Agent hereunder, or (ii) any action taken or
omitted to be taken in reliance upon any document, including any written notice
or instructions provided for in this Agreement, not only as to such document's
due execution and to the validity and effectiveness of its provisions, but also
as to the truth and accuracy of any information contained therein, which the
Escrow Agent shall in good faith believe to be genuine, to have been signed or
presented by a proper person or persons, and to conform with the provisions of
this Agreement.

                  (b) The Escrow Agent shall be bound only by the terms of this
Agreement and shall not be bound by or incur any liability with respect to the
Merger Agreement or any other agreement or understanding between WAXS and the
Shareholder Representative to which the Escrow Agent is not a party. The Escrow
Agent shall not have any duties hereunder except those specifically set forth
herein.

                  (c) In case any property deposited under this Agreement shall
be attached, garnished or levied upon or pursuant to any order of court, or the
delivery thereof shall be stayed or enjoined by an order or court, or any other
order, judgment or decree shall be made or entered by any court affecting such
property, or any part thereof, or any act of the Escrow Agent, the Escrow Agent
is hereby expressly authorized to obey and comply with all final writs, orders,
judgments, or decrees so entered or issued by any court without the necessity
of inquiry whether such court had jurisdiction; and, if the Escrow Agent obeys
or complies with any such writ, order, judgment, or decree, it shall not be
liable to any of the parties hereto or to any other person, firm, or
corporation by reason of such compliance.

         7.       Fees of Escrow Agent. The Escrow Agent shall be entitled to
reasonable fees for its services hereunder in an amount set forth on Schedule 2
hereto, which fees shall be paid by WAXS.

         8.       Removal or Resignation of Escrow Agent.

                  (a) WAXS and the Shareholder Representative, acting jointly,
shall have the right, upon written notice to the Escrow Agent, to remove the
Escrow Agent and appoint a successor. Upon acceptance of the duties of Escrow
Agent hereunder, a successor escrow agent shall be entitled to all of the
rights and powers as if originally named herein.


                                       4
<PAGE>   5


                  (b) The Escrow Agent may resign at any time by delivering
written notice of such resignation to WAXS and the Shareholder Representative,
in which event WAXS and the Shareholder Representative shall designate a
successor escrow agent. Upon appointment of a successor escrow agent by the
parties, and delivery of any cash held by the Escrow Agent to such successor,
the Escrow Agent shall be discharged from all further duties and liabilities
under this Agreement.

                  (c) If upon the effective date of any such removal or
resignation, no successor escrow agent shall have been designated, the Escrow
Agent shall have the right to tender into the registry or custody of any court
of competent jurisdiction any part or all of the Escrow Fund; provided,
however, that the Escrow Agent shall be entitled to its compensation earned
prior thereto and the provisions of Section 7 hereof shall survive any such
removal, resignation or tender.

         9.       Termination. This Agreement shall terminate on the first to
occur of (i) the later of (a) ten (10) days after the first (1st) anniversary
of the Closing Date, (b) the satisfaction of all claims pending on the first
(1st) anniversary of the Closing Date and (c) the disbursement of the entire
Escrow Fund in accordance with the terms hereof or (ii) a mutual consent signed
by WAXS and the Shareholder Representative.

         10.      Notices and Instructions. All notices and other communications
given or made pursuant hereto must be in writing and will be deemed to have

3.  PROCEDURE

         3.1 Lender will keep records of all Obligations and Collateral that is
in its possession, appropriately marked to show the interest of Participant
therein, and Participant or its designees may inspect or copy same at
reasonable times during normal business hours. Lender will, from time to time,
promptly following the execution thereof, furnish Participant with copies of
future Transaction Agreements relating to Term Loan B, and with such additional
information as Lender may have and may deem appropriate to provide to
Participant with respect to such Transaction Agreements; provided, however,
that Lender shall not be liable to Participant for any damages resulting from
Lender's failure to provide such copies of such future Transaction Agreements
or such information, except if Lender's failure is the result of gross
negligence or willful misconduct.

         3.2 During the term of this Agreement, Lender will deliver monthly
statements to Participant showing the status of the Term Loan B Transactions
and the Obligations as of the last day of the preceding month and the activity
during such preceding month. Any accounting rendered by Lender to Participant
presumptively shall be deemed correct and binding unless Participant notifies
Lender by certified mail, return receipt requested, to the contrary, within 30
days after the date when each such accounting is mailed or otherwise delivered
to Participant.

         3.3 Participant acknowledges that Lender has not made and does not
make any representations or warranties, express or implied, as to Borrower's
financial condition, or with respect to the validity, enforceability,
collectibility, priority, or perfection of any of the Transaction Agreements,
the Transactions, or the Collateral, and that Participant is fully familiar
with and has made its own independent evaluation and determination thereof.
Lender represents and warrants to Participant that Lender is the legal owner of
the interest in Term Loan B being conveyed hereunder, that Lender has the full
right, power and authority to assign, transfer and convey such interest, and
that such interest is being transferred free and clear of any claims, liens or
interests of any third parties. Participant expressly acknowledges: (a) that,
except as expressly provided hereinabove, Lender has not made any
representations or warranties to it of any sort whatsoever and that no act by
Lender hereafter taken, including any review of the affairs of Borrower or of
any guarantors, shall be deemed to constitute any representation or warranty by
Lender to Participant; (b) that Participant will continue to make its own
independent investigation of the financial condition and affairs, and its own
appraisal of the creditworthiness, of Borrower or any guarantors in connection
with the Transactions; and (c) that Lender shall have no duty or
responsibility, either initially or on a continuing basis, to provide
Participant with any credit or other information except as expressly provided
for herein.

         3.4 Because Participant's Investment is a "last-out" participation, it
is expected that Participant's Investment will remain fully funded at all times
prior to the Term Loan B Maturity Date (as such term is defined in the Loan
Agreement). Except as provided in Section 5.1 hereof in the event that (i)
Lender shall have accelerated the maturity of the Obligations based on
Borrower's default under the Transaction Agreements, or (ii) the Obligations
shall have matured in accordance with their terms and not have been repaid in
full, Participant hereby agrees with Lender that all amounts received by
Lender, whether by Collections or otherwise, shall be applied to Borrower's
loan account with Lender at such time and in such manner as is provided in the
Transaction Agreements, and shall be applied to the repayment of the
Obligations as follows:

           (a) first, to the repayment of all Obligations then due and payable
to Lender (including, without limitation, all accrued and unpaid interest with
respect to Obligations other than Term Loan B then due and payable to Lender
and all accrued and unpaid Foothill Expenses (as defined in the Loan Agreement)
then due and payable to Lender (other than Participant Expenses), but excluding
Obligations in respect of Term Loan B);

           (b) second, to the repayment of all accrued interest with respect to
Term Loan B then due and payable with respect to Term Loan B;

           (c) third, to the repayment of all accrued and unpaid fees
(including, without limitation, the Amendment Fee) and all Participant Expenses
in each case then due and payable with respect to Term Loan B;

           (d) fourth, to the repayment of all outstanding Obligations (other
than Obligations in respect of Term Loan B); and

           (f) fifth, to the repayment of all unpaid principal of, or other
Obligations in respect of, Term Loan B.

           All payments hereunder shall be made by wire transfer according to
wiring instructions delivered by each party to the other party hereto.

         3.5 (a) Participant's Investment hereunder shall accrue interest in
accordance with the terms and conditions of the Loan Agreement. Except as
provided in Section 5.1 hereof in the event that (i) Lender shall have
accelerated the maturity of the Obligations based on Borrower's default under
the Transaction Agreements, or (ii) the Obligations shall have matured in
accordance with their terms and not have been repaid in full, Lender agrees
that, upon receipt by Lender of payments in respect of Obligations then due and
payable with respect to Term Loan B, all such amounts with respect to
Participant's Investment hereunder shall be promptly paid to Participant in
United States Dollars, in accordance with this Section 3.5. Under any
circumstances in which Participant shall not be entitled to receive payments
with respect to Participant's Investment as herein provided, then Participant's
right to the return of Participant's Investment thereafter shall be subject to
Section 5.1 hereof without regard to Lender's declaration of Borrower's loan
account to be in liquidation pursuant to Section 5.1 hereof.


                                       5

                  (b) Participant shall not be entitled to any compensation
based upon any float, or any similar charges provided under the Transaction
Agreements, nor shall Participant share in the Closing Facility Fee, any
Anniversary Facility Fee, any Unused Line Fee, any Servicing Fees, or any other
fees paid by Borrower to Lender, except for the Amendment Fee as provided
herein. Participant shall not share in any financial examination, documentation
or appraisal fees paid to Lender. Participant shall not share in any recovery
by Lender of out-of-pocket expenses incurred by Lender and reimbursable by
Borrower except to the extent that such expenses are "extraordinary expenses"
(as hereinbelow defined) with respect to which Participant theretofore paid to
Lender its pro-rata share (based on Participant's Ratable Share of the
Obligations) thereof.

                  (c) Participant shall be entitled to the entire portion of
the Amendment Fee (in the amount of $225,000) that is due and payable on
November 1, 2000 (except to the extent such portion of the Amendment Fee shall
not be payable by Borrower under the terms of the Eleventh Amendment), as and
when such Portion of the Amendment Fee shall be due and payable by Borrower.

                  (d) Participant shall be entitled, if and to the extent that
such amounts are received in cash by Lender, to all Participant Expenses paid
or incurred by Participant and which are subject to reimbursement by Borrower
in accordance with the provisions of the Eleventh Amendment or the Loan
Agreement as amended thereby.

         3.6 In the event that Lender is required, for any reason, to refund or
repay to Borrower or any other person all or any portion of any payment
previously made to Lender with respect to Term Loan B and which has been paid
to Participant and applied to reduce Participant's Investment therein,
Participant shall remit to Lender such amount as was previously paid to
Participant that is required to be so refunded or repaid by Lender, and
Participant's Investment shall be increased accordingly.

         3.7 Lender shall not have, and does not assume, any liability to
Participant for the repayment of Participant's Investment or interest and fees
thereon, or reimbursement of expenses in connection therewith, to the extent
that such funds are not received from Borrower or collected from the proceeds
of the Collateral, except for losses occasioned by Lender's gross negligence or
willful misconduct.

         3.8 Lender shall bear all costs and expenses of managing and servicing
the Transactions except for extraordinary expenses, which shall be borne by
Lender and Participant pro-rata (based upon Participant's Ratable Share of the
Obligations), and for which Participant shall reimburse Lender upon demand for
Participant's pro-rata share (based upon Participant's Ratable Share of the
Obligations) thereof. The term "extraordinary expenses" shall consist of any
reasonable out-of-pocket costs and expenses, and shall include, but not be
limited to, reasonable attorneys fees and disbursements, court costs and
reasonable fees of any outside agency, incurred in connection with the
enforcement of any of Lender's rights and remedies after the date of this
Agreement against Borrower or any guarantors, arising under the Transaction
Agreements, or with regard to any of the Collateral, or in defending any action
or opposing any claim asserted at any time by Borrower or any of its
stockholders or any guarantors or any receiver or trustee in


                                       6
<PAGE>   7

bankruptcy, or by any other party against Lender or Participant caused by any
alleged claim of usury, ultra vires act or invalidity, any alleged preferential
or fraudulent transfer, or any other claim (other than a claim resulting from
Lender's gross negligence or willful misconduct) in connection with the
Transactions or the Collateral or any recovery on account of such claim;
provided, however, that Participant will be liable only if such fees or costs
are incurred on or after the Eleventh Amendment Closing Date, or such claims
relate to Transactions occurring on or after the Eleventh Amendment Closing
Date and prior to the effective date of termination of this Agreement, or such
fees or costs are incurred or arise while, or relate to Transactions or
Collateral occurring or existing while, Borrower's loan account shall be in a
liquidation declared prior to the effective date of termination of this
Agreement. Lender promptly shall provide Participant with notice of the
assertion of any action or claim described in the immediately preceding
sentence; provided, however, that Lender shall not be liable to Participant,
nor shall Participant be relieved of its obligations under this Section 3.8,
unless Lender fails to provide such notice willfully or as a result of gross
negligence. Extraordinary expenses shall not include any expenses of ordinary
overhead or ordinary payments made to clerical personnel or executives of
Lender. Participant also shall reimburse Lender, on demand, for Participant's
pro-rata share (based upon Participant's Ratable Share of the Obligations) of
all amounts paid by Lender in settlement or compromise of any such claim or
action (subject to the same provisos as set forth above), except in the event,
and in such case then except only to the extent, that such claim or action
arose out of the gross negligence or willful misconduct of Lender. Any such
settlement or compromise shall require the prior written approval of
Participant (which approval shall not be unreasonably withheld, conditioned, or
delayed). If Borrower's loan account is not in liquidation under Section 5.1,
prior to requiring Participant to pay its share of any extraordinary expenses,
Lender first shall make reasonable endeavors to charge same to Borrower and
collect same from Borrower, provided that if no revolving Advances are
available to Borrower under the Transaction Agreements and Borrower fails or
refuses to pay same promptly upon demand by Lender, Lender may require
Participant to pay its share without having to first declare Borrower's loan
account in liquidation, commence legal proceedings against Borrower, or proceed
against Collateral. If and to the extent that Participant defaults in its
obligations to make any payment to Lender as required pursuant to this Section
3.8, such amount shall be deducted from the amount of Participant's Investment
hereunder.

         3.9 If Participant defaults in its obligations to make any payment to
Lender as required hereunder, including without limitation the failure to make
payment of any extraordinary expenses (as that term is defined in Section 3.8
hereof), within 15 Business Days of the date on which notice of Participant's
failure to make such payment is received by Participant, then the amount of any
such payment, including without limitation any such unpaid extraordinary
expenses, shall be deducted from the amounts otherwise payable to Participant
in repayment of Participant's Investment or from any other amounts to which it
might otherwise be entitled hereunder. All amounts that would have been
distributed to Participant before the preceding sentence will instead be
retained by Lender and applied to reduce amounts advanced by Lender under the
Transaction Agreements in connection with any such unpaid extraordinary
expenses for which Participant has failed to fund its pro rata share (based
upon Participant's Ratable Share of the Obligations).

4.  MANAGEMENT

         4.1 (a) Participant acknowledges that its interest in Term Loan B,
together with the Agreements, Transactions, Obligations, Collateral, and
Collections in respect of Term Loan B, is derivative of Lender's interest in
the same, and that, as between Participant and Lender, Lender shall have the
sole right and authority in all respects to make decisions with respect to the
same, to deal with Borrower with respect to the same, and to administer
(including making legal claims with respect to the same and appearing in court
in connection with the enforcement of, or on account of, such claims) Lender's
and Participant's interest in the same. All of the Obligations and other
Transactions shall be made and conducted in Lender's name, and all of the
Collateral and Collections shall be held by or on behalf of Lender in Lender's
name. Lender shall have the right to administer the Transaction Agreements, to
perform and enforce the terms thereof, and to exercise all privileges and
rights exercisable or enforceable by Lender thereunder, according to Lender's
discretion and in the exercise of its normal business judgment. Lender hereby
expressly appoints Participant as Lender's agent for the purpose of perfecting
Lender's security interest in any of the Collateral that may at any time come
into the possession of Participant. Lender shall have the continuing and sole
right to enter into and agree to amendments, waivers, modifications, and
releases with respect to the Transaction Agreements, the Transactions, and the
Collateral. In the event of a bankruptcy filing by Borrower or against
Borrower, and in the event of any other insolvency proceeding involving
Borrower, Lender, and not Participant, shall have the sole right and authority
to file a claim on account of the interest of Lender and Participant in Term
Loan B, or the Agreements, Transactions, Obligations, Collateral, and
Collections in respect of Term Loan B, to appear in bankruptcy court or other
court on account of the same, and to otherwise take such action as Lender may
deem appropriate in order to collect on the same. Lender shall not be liable to
Participant for any action taken or omitted or for any error in judgment,
except for its own gross negligence or willful misconduct.

                  (b) Anything contained herein to the contrary
notwithstanding, for so long as there shall be any outstanding Obligations with
respect to Term Loan B, Lender shall not, without the prior written consent of
Participant, (i) agree to any amendment, modification or waiver of any of the
rate of interest, principal amount, or maturity of Term Loan B, or the
Amendment Fee, or (ii) make any additional Advances under and as defined in the
Loan Agreement in excess of the aggregate amount of $40,000,000 principal at
any one time outstanding.

                  (c) Anything contained herein to the contrary
notwithstanding, if at any time all Obligations of Borrower to Lender (other
than with respect to Term Loan B) have been paid in full in cash (or as
otherwise agreed by Lender in its discretion) and there shall remain any
outstanding Obligations with respect to Term Loan B, Lender shall assign to
Participant or Participant's designee, without any representation, recourse, or
warranty whatsoever, except as expressly set forth below in this paragraph,
Participant's Percentage in Lender's right, title, and interest with respect to
the Transactions and the Transaction Agreements and all security interests
granted therein with respect to Term Loan B, at no expense to Participant other
than the reimbursement by Participant (to the extent not paid by Borrower) of
the reasonable out-of-pocket expenses of Lender and its legal counsel in
connection with documenting and effecting


                                       8
<PAGE>   9

such assignment, such documentation and assignment to be in such form as Lender
and Participant shall mutually agree, whereupon Lender shall be relieved from
any further duties, obligations, or liabilities to Participant pursuant to this
Agreement. In connection with any assignment by Lender pursuant to this
paragraph, Lender shall be deemed to have warranted to the assignee that Lender
is the legal owner of the interests being assigned, that Lender has the full
right, power and authority to assign, transfer and convey such interests, and
that such interests are being transferred free and clear of any claims, liens
or interests of any third parties (other than Participant or Participant's
designee).

                  (d) Anything contained herein to the contrary
notwithstanding, for so long as there shall be any outstanding Obligations with
respect to Term Loan B, in all matters in respect of the portion of the
Amendment Fee payable to Participant (including, without limitation, the form
of payment thereof), and with respect to any extension of the Term Loan B
Maturity Date to a date not later than October 1, 2003, Lender shall at all
times act pursuant to the instructions of Participant.

                  (e) Anything contained herein to the contrary
notwithstanding, for so long as there shall be any outstanding Obligations with
respect to Term Loan B, Lender shall not release any lien of Lender in any
material portion of the Collateral securing Term Loan B except in accordance
with the Transaction Documents and in connection with the receipt by Borrower
or Lender of proceeds in amount not less than the fair market value of all
assets subject to such lien release, such proceeds to be applied to the
Obligations.

         4.2 Subject to the last sentence of Section 4.1 hereof, Lender shall
exercise the same care and discretion in managing and servicing the Obligations
(including, without limitation, Term Loan B) and other Transactions, in making
Collections in connection therewith, and in entering into any compromise or
settlement with Borrower in connection therewith, as it would ordinarily
exercise with respect to loans for which it has no participant. To the extent
of Participant's interests hereunder, Lender is not, and shall not under any
circumstances be deemed to be, a fiduciary for Participant in administering and
servicing the Transaction Agreements or in any other capacity. Nothing
contained herein shall confer upon either Lender or Participant any proprietary
interest in, or subject either of them to any liability for or with respect to,
the business, assets, profits, losses, or obligations of the other, except only
as to the Obligations and other Transactions to the extent of the participation
hereby created.

         4.3 Participant shall not sell, pledge, assign, sub-participate, or
otherwise transfer all or any part of its interest hereunder to any third
person without Lender's prior written consent. Lender may further participate
or otherwise transfer or assign its interest in the Obligations, the
Collateral, the Collections, or the Transactions to any third person at any
time (in any such case a "Sale") without the consent of participant; provided,
however, that should Lender offer to make any such Sale to any third person,
(i) notwithstanding any such Sales, Lender shall at all times retain the right
to vote or otherwise control any such third party's share with respect to any
right of any such third party's share to consent to any amendment,
modification, waiver or consent under the Transaction Agreements, and (ii) any
such Sale shall be made subject to Participant's rights and Lender's
obligations under this Agreement.


                                       9
<PAGE>   10

         4.4 All payments with respect to the Obligations (including, without
limitation, any payment by way of setoff, banker's lien, counterclaim,
realization on Collateral or otherwise) received by Participant at any time,
from any source other than Lender as provided in this Agreement, shall be
immediately forwarded to Lender for application pursuant to the terms of this
Agreement; provided that, if Lender has outright assigned the Term Loan B to
Participant, this Section 4.4 shall not apply to payments received by
Participant with respect to the Term Loan B from and after the effectiveness of
such assignment.

         4.5 In the event a voluntary or involuntary bankruptcy case is
commenced by or against Borrower, and provided that Lender has not outright
assigned the Term Loan B to Participant, Lender shall file a proof of claim in
such bankruptcy case with respect to the Term Loan B (which may be separate
from the proof of claim filed with respect to the other Obligations) and Lender
shall, following the final and full payment of all other Obligations other than
the Term Loan B as provided in this Agreement, remit to Participant any
property or other distribution received by Lender on account of such claim with
respect to the Term Loan B. Notwithstanding the foregoing, in the event of such
bankruptcy case and provided that Lender has not outright assigned the Term
Loan B to Participant, subject to Lender's duties set forth in Section 4.2 of
this Agreement, Participant agrees that Lender shall have no liability to
Participant for, and Participant waives any claim it may hereafter have against
Lender arising out of, (a) Lender's consent to the use of cash collateral
pursuant to Section 363 of the United States Bankruptcy Code (Title 11 U.S.C.
101 et seq., as amended from time to time, the "Bankruptcy Code"), (b) Lender's
agreement to extend additional credit to Borrower, as debtor-in-possession, or
to a trustee, pursuant to Section 364 of the Bankruptcy Code, (c) pursuant to
the provisions of this Agreement, Lender's application of payments received in
such case, including the application to Obligations accruing after the
commencement of such case (including without limitation interest, fees, costs
and other charges, whether or not allowed as claims in such case), and (d)
Lender's election made pursuant to Section 1111(b)(2) of the Bankruptcy Code.

5.  LIQUIDATION

         5.1 If at any time (i) Lender shall have accelerated the maturity of
the Obligations based on Borrower's default under the Transaction Agreements,
or (ii) the Obligations shall have matured in accordance with their terms and
not have been repaid in full, Lender may, at its option, declare Borrower's
loan account in liquidation. Thereafter, notwithstanding the provisions of
Section 3.4 hereof, all Collections received shall be applied:

                  (a) first, to the payment of all of Lender's share of all
accrued and unpaid expenses to the extent earned or due and payable in
accordance with the Loan Agreement (including the reimbursement of
extraordinary expenses, financial examination expenses, and loan documentation
review charges, and including any such expenses that, but for the provision of
the Bankruptcy Code would have accrued or otherwise been payable) in respect of
the Obligations other than Term Loan B owing by Borrower, until paid in full in
cash;

                  (b) Second, to the payment of all of Lender's share of all
accrued and unpaid interest and any unpaid fees to the extent earned or due and
payable in accordance with the Loan


                                      10
<PAGE>   11

Agreement (including any interest or unpaid fees that, but for the provision of
the Bankruptcy Code would have accrued or otherwise been payable) in respect of
the Obligations other than Term Loan B, until paid in full in cash;

                  (c) Third, to the payment of all of Lender's share of the
unpaid Obligations other than Term Loan B, until paid in full in cash;

                  (d) Fourth, to the extent that Lender has funded any part of
Term Loan B, to the payment of all of Lender's share of all accrued and unpaid
expenses to the extent earned or due and payable in accordance with the Loan
Agreement (including the reimbursement of extraordinary expenses, financial
examination expenses, and loan documentation review charges, and including any
such expenses that, but for the provision of the Bankruptcy Code would have
accrued or otherwise been payable) in respect of the Obligations consisting of
Term Loan B, until paid in full in cash;

                  (e) Fifth, to the extent that Lender has funded any part of
Term Loan B, to the payment of all of Lender's share of all accrued and unpaid
interest and any unpaid fees to the extent earned or due and payable in
accordance with the Loan Agreement (including any interest or unpaid fees that,
but for the provision of the Bankruptcy Code would have accrued or otherwise
been payable) in respect of the Obligations consisting of Term Loan B, until
paid in full in cash;

                  (f) Sixth, to the extent that Lender has funded any part of
Term Loan B, to the payment of all of Lender's share of the Obligations
consisting of Term Loan B, until paid in full in cash;

                  (g) Seventh, to the payment of all of Participant's share of
all accrued and unpaid expenses to the extent earned or due and payable in
accordance with the Loan Agreement (including the reimbursement of
extraordinary expenses, and including any such expenses that, but for the
provision of the Bankruptcy Code would have accrued or otherwise been payable)
in respect of the Obligations consisting of Term Loan B, until paid in full in
cash;

                  (h) Eighth, to the payment of all of Participant's share of
all accrued and unpaid interest and any unpaid fees to the extent earned or due
and payable in accordance with the Loan Agreement (including any interest or
unpaid fees that, but for the provision of the Bankruptcy Code would have
accrued or otherwise been payable) in respect of Obligations consisting of Term
Loan B, until paid in full in cash; and

                  (i) Ninth, to the payment of Participant's share of the
Obligations consisting of Term Loan B.

                  Participant understands that Participant's participation is a
last-out participation as to Participant's Investment, subject only to
Participant's right to receive any amounts due to Participant pursuant to
Section 3.5 when Borrower's Obligations have not been accelerated.


                                      11
<PAGE>   12

6.  TERMINATION

         6.1 Except during any period when Borrower's loan account shall be in
liquidation, this Agreement and the participation hereby created shall
terminate on the full and final repayment in cash of all Obligations of
Borrower to Lender under the Transaction Agreements in accordance with their
terms and payment in full in cash of Participant's investment in Term Loan B
and all other amounts due to Participant hereunder. Any termination hereunder
notwithstanding, Participant's obligations to make payments under the
provisions of Section 3.6 hereof arising during the effectiveness of this
Agreement shall survive any such termination of this Agreement. If, prior to
the effective date of such termination, Lender declares Borrower's loan account
to be in liquidation, then the provisions of Section 5.1 hereof shall govern
notwithstanding the provisions of this Section 6, and the Collections shall
thereafter be distributed pursuant to the provisions of Section 5.1, based on
the amount of Participant's Investment, as of the date the liquidation is
declared by Lender.

         6.2 In the event that the Obligations shall have matured in accordance
with their terms and not have been repaid in full, anything contained herein to
the contrary notwithstanding, Lender shall have the option on or after such
date to repay to Participant the outstanding balance of Participant's
Investment, plus Participant's accrued interest and fees (including, without
limitation, the Amendment Fee), plus any unreimbursed Participant Expenses due
and payable pursuant to the Eleventh Amendment or the Loan Agreement as amended
thereby, calculated pursuant to Section 3.5 hereof, to the date of purchase.
Upon repayment in full to Participant, each party shall thereupon be relieved
of any liability to the other party in connection herewith, except that the
provisions of Section 3.6 hereof shall survive after termination. In the event
that Lender shall not exercise its option to repay Participant pursuant to this
Section 6.2, all Obligations and other Transactions in existence or entered
into on or after the maturity of the Obligations in accordance with their terms
shall be accounted for as if Borrower's loan account were in liquidation under
Section 5.1. If Borrower's loan account is in or shall thereafter go into
liquidation, the Collections shall thereafter be distributed pursuant to the
provisions of Section 5.1, based on the amount of Participant's Investment, as
of the date the liquidation is declared by Lender.

7.  GENERAL

         7.1 All notices provided for herein shall be in writing and mailed to
the respective parties at the addresses set forth next to their signatures
below, or at such other addresses as either of them shall have specified to the
other in writing.

         7.2 This Agreement (a) shall be binding upon and inure to the benefit
of the parties hereunder and their respective legal representatives,
successors, and permitted assigns, (b) shall be governed, construed, and
interpreted in all respects in accordance with the laws of the State of
California, and (c) may not be modified, amended, terminated, or otherwise
changed orally or by any course of dealing or in any manner except by an
agreement in writing signed by the duly authorized officer of the party to be
charged.


                                      12
<PAGE>   13

         7.3 Each of the parties hereby expressly submits and consents in
advance to the non-exclusive jurisdiction of the Superior Court of the State of
California in the County of Los Angeles and jurisdiction of the United States
District Court for the Central District of California in any action or
proceeding commenced by the other in such court with reference to any claim or
dispute between the parties pertaining directly or indirectly to this Agreement
or to any matter arising therefrom. Each of the parties hereby waives the right
to trial by jury in any such action or proceeding, and personal service of any
summons, complaint, writ, process, or other papers may be by registered or
certified mail addressed to the party to be served at the address to which
notices are to be sent pursuant to Section 7.1 hereof.

         7.4 If any action at law or equity is brought to enforce or interpret
the provisions of this Agreement, the prevailing party shall be entitled to
recover its reasonable attorneys fees, which may be determined by the court in
the same action or in a separate action brought for that purpose, in addition
to any other relief to which that party may be entitled.

         7.5 No term or provision contained in this Agreement, and no other
agreement between the parties hereto, is intended to be, or shall it be
construed to be, the formation of a partnership or joint venture between Lender
and Participant.

         7.6 It is understood and agreed that Lender and Participant, or any
affiliate of either thereof may, from time to time, lend money to or otherwise
generally engage in any business with Borrower and any affiliate of Borrower.

         7.7 This Agreement and the duties and obligations contained herein
shall be solely for the benefit of the parties hereto, their affiliates, and
future participants; no third party shall have any rights hereunder as a third
party beneficiary or otherwise.

         7.8 To the extent that any payment of any amount by Lender to
Participant is deferred as the result of a liquidation pursuant to Section 5.1
hereof, Participant's ultimate right to collect such amount, or to attempt to
collect such amount, from Borrower (subject to Lender's prior right to be
repaid its share of the Obligations in full as more particularly provided
hereinabove) shall not be deemed to have been waived or forfeited vis-a-vis
Borrower, but merely deferred to the prior rights of Lender.

         7.9 Unless the context of this Agreement clearly requires otherwise,
references to the plural include the singular, references to the singular
include the plural, the term "including" is not limiting, and the term "or"
has, except where otherwise indicated, the inclusive meaning represented by the
phrase "and/or." The words "hereof," "herein," "hereby," "hereunder," and
similar terms in this Agreement refer to this Agreement as a whole and not to
any particular provision of this Agreement. Section, subsection, clause,
schedule, and exhibit references are to this Agreement unless otherwise
specified. Any reference in this Agreement to the Loan Agreement or any of the
Loan Documents shall include all alterations, amendments, changes, extensions,
modifications, renewals, replacements, substitutions, and supplements, thereto
and thereof, as applicable.

<PAGE>   14

         7.10 This Agreement may be executed in any number of counterparts and
by different parties on separate counterparts, each of which, when executed and
delivered, shall be deemed to be an original, and all of which, when taken
together, shall constitute but one and the same Agreement. Delivery of an
executed counterpart of this Agreement by telefacsimile shall be equally as
effective as delivery of a manually executed counterpart of this Agreement. Any
party delivering an executed counterpart of this Agreement by telefacsimile
also shall deliver a manually executed counterpart of this Agreement but the
failure to deliver a manually executed counterpart shall not affect the
validity, enforceability, and binding effect of this Agreement.

         7.11 Participant is not purchasing Participant's Investment on behalf
of one or more employee benefit plans, or with proceeds which constitute "plan
assets," as defined in the Employee Retirement Income Security Act of 1974, as
amended, and the rules and regulations promulgated thereunder.

         7.12 (a) If Lender is sued or threatened with suit by a receiver or
trustee in any bankruptcy or other insolvency proceeding involving Borrower or
any other Obligor (i) on account of any alleged preferential or fraudulent
transfer received or alleged to have been received, directly or indirectly,
from Borrower or any other such Person, to the extent attributable to Term Loan
B or Participant's Investment, or (ii) relating to the equitable subordination
of the Obligations or the recharacterization of any of the Obligations as
equity, to the extent attributable to Term Loan B or the Participant's
Investment, then Participant shall (A) indemnify, defend and hold Lender
harmless from any such suit, claim or action and (B) repay or reimburse Lender
for all expenses, costs and reasonable attorneys fees paid or incurred, or
payments made by Lender, in connection therewith. To the extent that any
amounts previously paid in respect of the Obligations are recovered from
Lender, such amounts shall be reinstated as part of the Obligations, repayable
in accordance with the priorities established herein and in the Loan Agreement.

              (b) Participant hereby indemnifies Lender against, and agrees
to hold Lender harmless from, any and all claims, demands, actions,
controversies, suits, liabilities, losses, damages, judgments, awards, costs
and expenses (collectively, "Losses"), including, without limitation, all
reasonable attorneys fees and disbursements and reasonable time charges of
in-house counsel of Lender, arising by reason of or resulting from (i) any
breach of Participant's representations, warranties or covenants contained
herein, (ii) any Losses described in Section 7.12(a) above, (iii) any Losses
directly arising from the making, administration, collection or enforcement of
the Term Loan B or any interest in Collateral securing the Term Loan B, or that
would not have occurred but for the Participant's Investment or the entering
into of this Agreement, in each case save and except for any such Losses
resulting from the gross negligence or willful misconduct of Lender, (iv) any
sale, assignment or transfer of, or grant of a subparticipation in, all or any
part of the Participant's Investment, or (v) Lender's following any direction
or request of Participant with respect to the Participant's Investment.
Participant's obligation to indemnify Lender under this Agreement, including,
without limitation, under Section 7.12(a) hereof, will continue notwithstanding
any termination or expiration of this


                                      14

Agreement or the Loan Agreement, or any outright assignment of the Term Loan B
from Lender to Participant.

                            PARTICIPATION AGREEMENT

         This AMENDMENT NUMBER ONE TO PARTICIPATION AGREEMENT (this "Amendment")
is entered into as of May 23, 2000, by and between FOOTHILL CAPITAL CORPORATION,
a California corporation ("Foothill"), and, WORLD ACCESS, INC., a Delaware
