         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
Edward S. Soren ("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, 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,
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, pledge agreement, loan or
         credit agreement, note, bond, mortgage, indenture, lease or other
         agreement, instrument, permit, concession, franchise or license or
         violate any


   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
   3


         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
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.

         rule or law, or public policy, all other conditions and provisions of

         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
