Common Stock subject to such Conversion Unit shall again be available for
purposes of this Plan.

                  one or more of the following ways:

                                    (i)  in full in cash or in any combination
                           of cash and installment payments as may be determined
                           by the Administrative Committee; and/or

                                    (ii) subject to the consent of the
                           Administrative Committee, in shares of Common Stock

                           Market Value on the date of exercise of the Option
                           which is equal to the Option Price for the shares
                           being purchased.

                           If the Option Price is paid in whole or in part in
                  shares of Common Stock, any portion of the Option Price
                  representing a fraction of a share shall be paid in

                  determined under procedures established by the Administrative
                  Committee, and the Option Price shall be payable at such time
                  or times as the Administrative Committee, in its discretion,
                  shall determine. No shares shall be issued or delivered upon

                  made, the Optionee shall be considered for all purposes to be
                  the owner of the shares with respect to which payment has been
                  made. Payment of the Option Price with shares shall not
                  increase the number of shares of Common Stock which may be

                  6(E) and 6(F), Options may be exercised at such times, in such
                  amounts and subject to such restrictions as shall be
                  determined, in its discretion, by the Administrative
                  Committee.

                           (C) An Optionee may not transfer a Conversion Unit or
                  Option, or any portion thereof, without the prior written
                  consent of the Administrative Committee.

                           (D) As to those Optionees who become employees of
                  World Access, unless otherwise determined by the
                  Administrative Committee and set forth in the Stock Option

                           consent of World Access, or if an Optionee retires
                           under any retirement plan of World Access, any

                           be exercisable (to the extent exercisable on the date
                           of such event) by such Optionee (or, if applicable,
                           by such Optionee's permitted transferee) at any time
                           prior to the expiration date of such Option or within
                           three months after the date of such event, whichever

                           applicable, by such Optionee's permitted transferee),
                           or, if the Optionee shall fail to make testamentary
                           disposition of such Option or shall die intestate, by
                           the legal representative of the estate of such
                           Optionee, at any time prior to the expiration date of
                           such Option or within nine months after the date of
                           death, whichever is the shorter period. Following the

                           entitled to do so under the Will of the Optionee or
                           by such Optionee's legal representative (or by such
                           transferee) to the extent that such Option was
                           exercisable by the Optionee (or, if applicable, by
                           such Optionee's permitted transferee) at the time of
                           death at any time prior to the expiration date of

                           Option shall terminate at the time of such
                           termination of employment. In addition, if an

                           all Options held by the Optionee (or, if applicable,
                           by such Optionee's permitted transferee). For

                           or circumstances shall constitute "cause", to wit:

                           regulations or orders applicable to World Access; or
                           repeated and deliberate failure, after written

                           Chief Executive Officer of World Access or of the
                           Board.

                  with the written consent of, or an involuntary termination for
                  cause from, World Access, whether an Optionee is a Disabled
                  Optionee and whether an Optionee has engaged in the operation
                  or management of a business which is in competition with World
                  Access shall be determined in each case by the Administrative
                  Committee, and any such determination by the Administrative
                  Committee shall be final and binding.

respective Affiliates) of 50% or more of the combined voting power of World
Access' then outstanding securities (including securities exercisable for or
convertible into voting securities), or (iii) the consummation of a transaction
requiring shareholder approval and involving the sale, lease or exchange of all

10. Effect of this Plan on the Rights of Employees and Employer.

         Neither the adoption of this Plan nor any action of the Board or the
Administrative Committee pursuant to this Plan shall be deemed to give any
Employee any right to be granted a Conversion Unit or an Option under this Plan,
and nothing in this Plan, in any Conversion Unit granted under this Plan, in any
Option into which the same may be converted or in any Stock Option Agreement
shall confer any right to any Employee to continue in the employment of the
Corporation or any Subsidiary or World Access or interfere in any way with the
rights of the Corporation or any Subsidiary or World Access to terminate the
employment of any Employee at any time.

11.      Interpretation, Amendment, and Termination.

         Except as provided elsewhere in this Plan, in the event of any dispute
or disagreement as to the interpretation of this Plan or of any rule, regulation
or procedure, or as to any question, right or obligation arising from or related
to this Plan, the decision of the Board shall be final and binding upon all
persons. The Board may, in its discretion, amend or terminate this Plan at any
time. The Board of the Corporation may not, without the consent of World Access,
(a) increase the total number of shares which may be issued or delivered under
this Plan, (b) otherwise materially increase the benefits accruing to Employees
under this Plan. Termination of this Plan shall not affect the rights of
Optionees or their successors under any Conversion Units or Options outstanding
and not exercised in full on the date of termination.

12.      Withholding Taxes.

         The Corporation unilaterally or by arrangement with the Optionee shall
make appropriate provision for satisfaction of any obligation to withhold taxes
in the case of any grant, award, exercise or other transaction which gives rise
to a withholding requirement. An Optionee or

other person receiving shares issued upon exercise of an Option shall be
required to pay World Access in cash the amount of any taxes which World Access
is required to withhold.

         Notwithstanding the preceding sentence and subject to such rules as the
Administrative Committee may adopt, Optionees who are subject to Section 16(b)
of the Securities Exchange Act of 1934, as amended, and, if determined by the
Administrative Committee, other Optionees, may satisfy the referenced tax
payment obligation, in whole or in part, by election on or before the date that
the amount of tax required to be withheld is determined, to have the number of
shares received upon exercise of the Option reduced by a number of shares.

13.      Effective Date and Termination.

         This Plan shall be effective as of September 30, 1999.

         This Plan has been adopted in contemplation of the consummation of the
Merger. If the Merger is not consummated in accordance with the Merger
Agreement, as the same may be amended, then upon the earliest to occur of (i)
the termination of the Merger Agreement, (ii) a public announcement to the
effect that the Merger will not be consummated or (iii) upon the occurrence of
any other event by which the possibility of the consummation of the Merger is
irrevocably terminated, this Plan and all Conversion Units granted hereunder
shall forthwith and without further action by the Corporation or any Optionee be
and become terminated, void and of no further force or effect, and no Optionee
shall be entitled to any compensation or remuneration in respect of any
previously granted Conversion Unit.
