                          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:

<PAGE>   2


                                   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
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:

                                       2
<PAGE>   3

                  (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
                                       3
<PAGE>   4
covered under 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

                                       5
<PAGE>   6

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 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

                                       6
<PAGE>   7
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 the Surviving Corporation may direct as indemnity against
any claim that

                                       7
<PAGE>   8

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

                                       8
<PAGE>   9

         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 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

         and (K) such consents, approvals, orders, authorizations,

         or obtain would not have a Material Adverse Effect on 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".

         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

                                      11
<PAGE>   12

         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 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

         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

         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

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.

                           (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

         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

<PAGE>   14

         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

         SEC Reports or except as would not have a Material Adverse Effect on
         WAXS, neither WAXS nor any of its Subsidiaries has received notice

                  (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

                                      16

         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

                                      17

         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
         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.

                                      18

                                                                     EXHIBIT 2.1


                           (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,


                                       19
<PAGE>   20

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 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 which would not have a Material
         Adverse Effect on STAR. STAR is not aware of any threatened suspension,
         cancellation or invalidation of any STAR Permit. Except as set forth in
         the STAR SEC Reports or except as would not have a Material Adverse
         Effect on STAR, STAR has not received notice from either the FCC or any
         state public utilities commissions of any complaint filed therewith
         concerning STAR or any of its Subsidiaries, operations or services.

                  (i)      Absence of Certain Changes or Events. Except for
liabilities incurred in connection with this Agreement or the transactions
contemplated hereby, except as disclosed in the STAR SEC Reports filed prior to
the date of this Agreement, and except as permitted by Section 4.2, since
December 31, 1998 through and including the date hereof, (i) STAR and its
Subsidiaries have


                                       20
<PAGE>   21

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 STAR, 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 STAR and its
Subsidiaries operate and not specifically relating to STAR and its Subsidiaries.

                  (j)      Employee Benefits Matters.

                           (1)      Section 3.2(j)(l) of the STAR Disclosure
         Schedule sets forth a list of all material agreements, arrangements,
         commitments, and policies (i) which relate to employee benefits; (ii)
         which pertain to present or former employees, retirees, directors or
         independent contractors (or their beneficiaries, dependents or spouses)
         of STAR; and (iii) which are currently or expected to be adopted,
         maintained by, sponsored by, or contributed to by STAR or any other
         employer (a "STAR Affiliate") which, under Section 414 of the Code,
         would constitute a single employer with STAR (collectively referred to
         as "STAR 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.

                           (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 STAR.

                           (3)      STAR has made available to WAXS true,
         correct and complete copies of all of the current documents relating to
         the STAR Employee Benefit Plans, including, but not limited to: (i) all
         plan texts (including any subsequent amendments), trust instruments and
         other funding arrangements adopted or entered into in connection with
         each of the STAR Employee Benefit Plans; (ii) 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 (iii) the
         most recent Form 5500


                                       21
<PAGE>   22

         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.

                           (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.

                           (5)      None of the STAR Employee Benefit Plans (i)
         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 (ii) is liable for any federal,
         state, local or foreign taxes that would have a Material Adverse Effect
         on STAR. Except for such liabilities that would not have a Material
         Adverse Effect on STAR, there is no transaction in connection with
         which STAR or any STAR Affiliate could be subject to either a civil
         penalty assessed pursuant to ERISA Section 502, a tax imposed by Code
         Section 4975 or liability for a breach of fiduciary responsibility
         under ERISA.

                           (6)      Other than routine claims for benefits
         payable to participants or beneficiaries in accordance with the terms
         of the STAR Employee Benefit Plans, or relating to qualified domestic
         relations orders (as defined in Section 414(p) of the Code), there are
         no claims, pending or threatened, by any participant or beneficiary
         against any of the STAR Employee Benefit Plans or any fiduciary of any
         of the STAR Employee Benefit Plans that could have a Material Adverse
         Effect on STAR.

                           (7)      Neither STAR nor any STAR Affiliate has at
         any time maintained, sponsored or contributed to any "pension plan" as
         defined in ERISA Section 3(2) which is subject to Title IV of ERISA or
         contributed to any pension plan which is a "multiemployer plan" as
         defined in ERISA Section 3(37)(A).

                           (8)      Section 3.2(j)(8) of the STAR Disclosure
         Schedule sets forth a list of all agreements, arrangements, commitments
         and STAR Employee Benefit Plans, under which (i) any benefits will be
         increased, (ii) the vesting or exercisability of benefits will be
         accelerated, (iii) amounts will become immediately payable, and/or (iv)
         the immediate funding for any benefits is required, upon the occurrence
         of the transaction contemplated by this Agreement. Section 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 than employees with plans to retire. STAR has complied
         in all material respects 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 material labor relations problems
         (including threatened or actual strikes or work stoppages or material
         grievances).

                           (10)     Neither STAR nor any of its Subsidiaries is

                              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


                                       28
<PAGE>   29

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 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


                                       29
<PAGE>   30

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 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

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

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

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

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 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.

with all procedures and requirements applicable to it under Section 262 of the
DGCL.

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.

                  (b) Performance of Obligations of STAR. STAR shall have

STAR or any of its Subsidiaries to consummate the Merger and the other

would have a Material Adverse Effect on WAXS or the Surviving Corporation,
shall have been obtained; provided, however, that the provisions of this
Section 6.2(c) shall not be available to WAXS, if its failure to fulfill its
obligations pursuant to Section 5.3 shall have been the cause of, or shall have
resulted in, the failure to obtain such consent or approval.

reasonably satisfactory to WAXS.

                  (f) No Injunctions or Restraints; Illegality. No laws shall

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

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.

                           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


                                      39
<PAGE>   40
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 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
