ITEM 5            OTHER EVENTS

                  On June 17, 1998,  Executive  TeleCard,  Ltd. (the  "Company")
announced  that it had entered into an Agreement and Plan of Merger (the "Merger
Agreement") between the Company, IDX International,  Inc. ("IDX"),  EXTEL Merger
Sub No. 1, Inc., a wholly owned  subsidiary of the Company  ("Merger Sub"),  and
the  stockholders of IDX,  pursuant to which IDX will merge with and into Merger
Sub,  with the result that Merger Sub will  survive the merger as a wholly owned
subsidiary  of the Company  (the  "Merger").  The Merger,  which is subject to a
number  of  conditions,   including  approval  by  the  Federal   Communications
Commission, is expected to close in the third quarter of this year.

                  The Merger Agreement provides that all of the shares of common
stock, no par value,  and all of the shares of preferred stock, no par value, of
IDX,  issued and  outstanding  immediately  prior to the  effective  time of the
Merger  (excluding any treasury  shares),  shall be converted into and exchanged
for,  in the  aggregate,  the right to receive  (a)  500,000  shares of Series B
Convertible Preferred Stock, par value $.001 per share, of the Company ("Company
Convertible Preferred Stock"), the rights and preferences of which are set forth
in the form of  Certificate  of  Designations,  Rights  and  Preferences  of the
Company Convertible Preferred Stock which is attached as Exhibit A to the Merger
Agreement,  (b) warrants to purchase 2,500,000 shares of Common Stock, par value
$.001  per  share,  of the  Company  (subject  to  adjustments  based  upon  IDX
performance and the Company's market price), the terms of which are set forth in
the form of Warrant which is attached as Exhibit B to the Merger Agreement,  and
(c) $5,000,000 in cash, which amount is subject to decrease.

                  The foregoing  description  of the Merger  Agreement  does not
purport  to be  complete  and is  qualified  in its  entirety  by the  terms and
conditions of the Merger Agreement. The Merger Agreement (including the exhibits
thereto) is being filed herewith as Exhibit 2.1, and is  incorporated  herein by
reference.  A copy of the press release  announcing  the execution of the Merger
Agreement is attached as Exhibit 99.1 and is incorporated herein by reference.

Agreement,  and in  accordance  with  Virginia  Law, at the  Effective  Time (as

form as required by, and executed in accordance with the relevant provisions of,
Virginia Law, and in such form as approved by the Company and Acquiror  prior to
such filing  (the date and time of the filing of the  Articles of Merger or such
subsequent date or time specified therein being the "Effective Time").

         SECTION 1.3.      EFFECT OF THE MERGER.

                  At the  Effective  Time,  the effect of the Merger shall be as
provided in the  applicable  provisions  of Virginia Law.  Without  limiting the
generality of the foregoing,  and subject thereto, at the Effective Time, except
as otherwise provided herein, all the property, rights,  privileges,  powers and
franchises   of  Merger  Sub  and  the  Company  shall  vest  in  the  Surviving

Surviving  Corporation,  and  (b)  the  bylaws  of  Merger  Sub,  as  in  effect
immediately  prior to the Effective  Time,  shall be the bylaws of the Surviving

         SECTION 1.6.      CLOSING.

                  Subject to the terms and  conditions  of this  Agreement,  the
closing of the Merger (the "Closing") will take place as promptly as practicable
after  satisfaction  of the  latest to occur or, if  permissible,  waiver of the
conditions set forth in Article IX hereof (the "Closing  Date"),  at the offices
of Hogan & Hartson L.L.P., 555 Thirteenth Street, N.W., Washington,  D.C. 20004,

                  For  federal  income  tax  purposes,  the  parties  shall  use
reasonable efforts to qualify the Merger as a tax-free  reorganization under the
provisions  of Section  368(a) of the Internal  Revenue Code of 1986, as amended
(the "Code").

                                   ARTICLE II

         SECTION 2.1.      CONVERSION OF SECURITIES.

                  At the Effective Time, by virtue of the Merger and without any
action  on the  part of the  parties  hereto  or the  holders  of the  following
securities:

                  (a) Company Stock.  All of the shares of common stock,  no par
value ("Company Common Stock"), and all of the shares of preferred stock, no par
value,  of the Company  ("Company  Preferred  Stock",  and together with Company
Common Stock, "Company Stock"),  issued and outstanding immediately prior to the
Effective Time  (excluding  any shares  described in Section  2.1(c)),  shall be
converted  into and exchanged  for, in the  aggregate,  the right to receive (i)
500,000  shares of Series B Convertible  Preferred  Stock,  par value $.0001 per
share,  of Acquiror  ("Acquiror  Convertible  Preferred  Stock"),  and  Warrants
("Acquiror  Warrants") to purchase  2,500,000  shares of Common Stock, par value
$.001 per share,  of  Acquiror  ("Acquiror  Common  Stock"),  with the terms and
conditions  referred to in Section 2.1(b),  plus (ii) the amount of FIVE MILLION

<PAGE>



Stockholders   in  the   proportions  set  forth  opposite  the  names  of  such
Stockholders  in the column on Schedule 2.1 entitled  "Purchase Price Payable at
Closing" (the  "Stockholder  Percentages"),  with the cash portion being paid by
check or wire transfer of immediately available funds to an account specified by
the  Representative  (as defined below) in written  instructions  to Acquiror at
least  three (3)  business  days prior to the Closing  Date.  All such shares of

to have any rights  with  respect to such  shares of  Company  Stock,  except as
otherwise  provided herein or by law. Each such  certificate  shall be exchanged

Convertible  Preferred  Stock,  Acquiror  Warrants to purchase  the  appropriate
number of shares of Acquiror Common Stock and the appropriate cash amount as set
forth on Schedule  2.1 upon the  surrender  of such  certificate  as provided in

Warrants.  The terms of the Acquiror Convertible Preferred Stock shall be as set
forth in the proposed  Certificates of Designations for the Acquiror Convertible
Preferred  Stock,  a copy of which is attached as Exhibit A hereto,  which terms
include various  adjustments  through adjustments to the conversion price of the
Acquiror  Convertible  Preferred  Stock.  The Acquiror  Warrants shall be as set
forth in Exhibit B hereto,  which  terms  include  various  adjustments  through
adjustments to the exercise price of the Acquiror Warrants.

                  (c) Treasury Stock. All shares of capital stock of the Company
held in the  treasury of the Company  immediately  prior to the  Effective  Time
shall be  canceled  and  extinguished  without  any  conversion  thereof  and no
Acquiror  Convertible  Preferred  Stock,   Acquiror  Warrants,   cash  or  other
consideration shall be delivered or deliverable in exchange therefor.

                  (d) Merger Sub Stock.  Each share of common  stock,  par value
$.01 per share,  of Merger Sub issued and outstanding  immediately  prior to the
Effective  Time  shall  be  converted  into and  exchanged  for one (1) duly and
validly  issued,  fully  paid and  nonassessable  share of  common  stock of the
Surviving Corporation.

delivery to the Representative) at Closing certificates evidencing the shares of
Acquiror  Convertible  Preferred Stock issuable pursuant to Section 2.1(a),  the
Acquiror  Warrants  evidencing the right to purchase  shares of Acquiror  Common

collectible  accounts  receivable of the Company (on a consolidated basis) as of

         SECTION 3.6.      FINANCIAL STATEMENTS.

                                  STOCKHOLDERS

                  In addition to the  representations and warranties made by the

instruments,  certificates  and  agreements  executed  or to be executed by such
Stockholder  pursuant hereto,  and to consummate the  transactions  contemplated
hereby and thereby.

         SECTION 4.3.      ABSENCE OF VIOLATION.

this Agreement and all other documents, instruments, certificates and agreements
contemplated hereby to which such Stockholder is a party, the fulfillment of and
the compliance with the respective terms and provisions hereof and thereof,  and
the consummation of the transactions contemplated hereby and thereby, do not and
will not (a)  conflict  with,  or violate  any  provision  of,  any Laws  having
applicability to



                                      -20-

constitute a default under, any agreement to which such Stockholder is a party.

         SECTION 4.4.      RESTRICTIONS AND CONSENTS.

                  There are no  agreements,  Laws or other  restrictions  of any
kind to which  such  Stockholder  is party or  subject  that  would  prevent  or
restrict  the  execution,  delivery or  performance  of this  Agreement  by such
Stockholder.

         SECTION 4.5.      BINDING OBLIGATION.

                  This Agreement  constitutes,  and each  document,  instrument,
certificate and agreement to be executed by such  Stockholder  pursuant  hereto,
when executed and  delivered in accordance  with the  provisions  hereof,  shall
constitute,  a valid and binding obligation of such Stockholder,  enforceable in
accordance  with its  terms,  except as such  enforceability  may be  limited by
bankruptcy,  insolvency,  reorganization,  moratorium  and other similar laws of
general  applicability  relating to or affecting creditors' rights generally and
by the application of general principles of equity.

         SECTION 4.6.      NO REGISTRATION UNDER THE SECURITIES ACT.

                  Such  Stockholder  understands  that the  shares  of  Acquiror
Convertible  Preferred  Stock  and  Acquiror  Warrants  to  be  issued  to  such
Stockholder  under this Agreement have not been and will not be registered under
the Securities Act of 1933, as amended (the "Securities  Act"), in reliance upon
exemptions  contained in the  Securities  Act or  interpretations  thereof,  and
neither  such  shares  of  Acquiror  Convertible  Preferred  Stock  or  Acquiror
Warrants,  nor the Acquiror  Common Stock  issuable upon  conversion or exercise
thereof,  can be offered for sale,  sold or  otherwise  transferred  unless such
shares (the Warrants by their terms are not  transferable)  are so registered or
qualify for exemption from registration under the Securities Act.

         SECTION 4.7.      ACQUISITION FOR INVESTMENT.

                  The  shares  of  Acquiror  Convertible   Preferred  Stock  and
Acquiror Warrants to be issued to such Stockholder under this Agreement, and the
Acquiror  Common Stock issuable upon conversion or exercise  thereof,  are being
(or will be)  acquired  by such  Stockholder  in good  faith  solely for its own
account,  for investment and not with a view toward resale or other distribution
within the meaning of the  Securities  Act.  Such shares will not be offered for
sale,  sold  or  otherwise   transferred  by  such  Stockholder  without  either
registration or exemption from

                                      -21-



<PAGE>


registration  under the  Securities  Act (the  Warrants  by their  terms are not
transferable).

         SECTION 4.8.      EVALUATION OF MERITS AND RISKS OF INVESTMENT.

                  Such   Stockholder   has  such  knowledge  and  experience  in
financial and business  matters that such  Stockholder  is capable of evaluating
the merits and risks of the  Stockholder's  investment in the shares of Acquiror
Convertible  Preferred Stock and Acquiror Warrants to be acquired  hereunder and
the Acquiror  Common Stock issuable upon  conversion or exercise  thereof.  Such
Stockholder  understands and is able to bear any economic risks  associated with
such investment  (including,  without limitation,  the necessity of holding such
shares for an  indefinite  period of time,  inasmuch as the shares have not been
registered under the Securities Act). Each of the Stockholders is an "accredited
investor",  as that  term is  defined  in  Regulation  D  promulgated  under the
Securities  Act. Such  Stockholder  confirms that Acquiror has made available to
such  Stockholder  and its  representatives  and agents the  opportunity  to ask
questions  of the  officers  and  management  employees  of  Acquiror  about the
business  and  financial  condition  of  Acquiror  as  such  Stockholder  or its
representatives have requested.

relating to or affecting  creditors'  rights generally and by the application of
general principles of equity.

securities  laws in connection  with the issuance of Acquiror  Common Stock upon

laws,  Acquiror shall take such action necessary to register the Acquiror Common
Stock held by such  Stockholders  for public resale,  including  filing a Resale

information regarding Acquiror.  Acquiror shall use its best efforts to have the
Resale  Registration  Statement  declared  effective under the Securities Act as
promptly  as  practicable  after  such  filing.   Acquiror  shall  maintain  the
effectiveness  of the Resale  Registration  Statement  until all Acquiror Common
Stock registered pursuant to the Resale Registration Statement has been disposed
of by the  Stockholders or such Acquiror Common Stock is otherwise  eligible for
public resale under applicable securities laws.

Company on  substantially  the same  terms and  conditions  (including,  without
limitation, substantially the same title, duties, locations, salary compensation
and  benefits)  as those  enjoyed  by such  employees  immediately  prior to the
Effective Time; provided, however, that nothing in this Section 8.14 shall limit
or otherwise  restrict the ability of Acquiror or the Surviving  Corporation  to
terminate,  lay off or reduce the work hours with respect to the  employment  of

plans of Acquiror.

         SECTION 8.15.  SECOND BRIDGE LOAN.

                  If the Closing  Date has not  occurred on or prior to June 29,

                                                                       EXHIBIT A

                      SERIES B CONVERTIBLE PREFERRED STOCK

                  The  following  sections  set forth  the  powers,  rights  and
preferences,  and the qualifications,  limitations and restrictions  thereof, of
the  Corporation's  Series B Convertible  Preferred  Stock,  par value $.001 per
share  ("Series B  Preferred").  Capitalized  terms used  herein are  defined in
Section 6 below.

                  Section 1. Voting Rights.

                  Except as otherwise provided herein or as required by law, the
Series B  Preferred  shall  vote  with the  shares  of the  Common  Stock of the
Corporation  (and each other  class of stock so  voting),  and not as a separate
class, at any annual or special meeting of stockholders of the Corporation,  and
may act by written  consent in the same  manner as the Common  Stock,  in either
case upon the following basis: each holder of shares of Series B Preferred shall
be  entitled  to such  number of votes as shall be equal to 25% of the number of
shares of Common Stock into which such  holder's  aggregate  number of shares of
Series B Preferred are convertible pursuant to Section 5 below immediately after
the close of business on the record date fixed for such meeting or the effective
date of such written consent,  rounded up to the nearest whole number; provided,
however,  that the  Series B  Preferred  shall  not have any  voting  rights  in
connection with a Shareholder Approval (as defined below).

                  Section 2. No Redemption.

                  Series B Preferred shall not be redeemable.

                  Section 3. Dividend Rights.

                  Except as  otherwise  provided  herein or as  required by law,
holders of Series B Preferred  shall be entitled to receive  dividends only when
and as declared by the Corporation's Board of Directors with respect to Series B
Preferred, only out of funds that are legally available therefor and only in the
event that the  Corporation at the same time declares or pays any dividends upon
the Common Stock (whether payable in cash, securities or other property). In the
event that the Corporation  declares or pays any dividends upon the Common Stock
(whether  payable  in cash,  securities  or other  property)  on or prior to the
Adjustment Date, other than dividends  payable solely in shares of Common Stock,
the  Corporation  shall  also  declare  and pay to the  holders  of the Series B
Preferred,  at the same time that it  declares  and pays such  dividends  to the
holders of the Common Stock,  the




<PAGE>
dividends  which would have been  declared  and paid with  respect to the Common
Stock  issuable  upon  conversion  of the  Series  B  Preferred  had  all of the
outstanding  Series B Preferred been converted  immediately  prior to the record
date for such dividend,  or if no record date is fixed, the date as of which the
record holders of Common Stock entitled to such dividends are to be determined.

                  Section 4.  Liquidation Rights.

                  Upon  any   Liquidation,   after  the   payment  of  the  full
liquidation  preference of any series of preferred  stock senior to the Series B
Preferred, the holders of Series B Preferred shall be entitled to participate in
distributions  to holders of the Common  Stock  (along  with each other class of
stock with similar  rights) such that the holders of Series B Preferred  receive
aggregate  distributions  equal to the  amounts  that such  holders  would  have
received if the Series B Preferred  Stock had been  converted  into Common Stock
immediately prior to such Liquidation.

                  Section 5. Conversion.

                  The holders of the Series B Preferred shall have the following
rights with respect to the  conversion of the Series B Preferred  into shares of
Common Stock:

                  5A.  Optional  Conversion.  At any time and from  time to time
after the issuance thereof,  subject to and in compliance with the provisions of
this  Section  5, any  shares of Series B  Preferred  may,  at the option of the
holder,  be converted at any time into  fully-paid and  nonassessable  shares of
Common  Stock  (provided,  that if the  Adjustment  Date  has  occurred  but the
Determination Date has not occurred, the Corporation may postpone any conversion
of  Series B  Preferred  until  the  Determination  Date,  but then  shall  take
appropriate  steps to put each holder of Series B Preferred who  exercised  such
holder's right to convert Series B Preferred  shares prior to the  Determination
Date in the same  economic  position as if such  conversion  had occurred on the
date of exercise and the Common Stock received upon such  conversion  held until
the Determination  Date). The number of shares of Common Stock to which a holder
of Series B Preferred  shall be entitled  upon  conversion  shall be the product
obtained  by  multiplying  the  "Series  B  Conversion   Rate"  then  in  effect
(determined  as  provided  in  Section  5B) by the  number of shares of Series B
Preferred being converted.

                  5B. Series B Conversion Rate.

                  (i) Conversion Rate Formula.  The conversion rate in effect at
any time for  conversion  of the Series B Preferred  (the  "Series B  Conversion
Rate")  shall be the product of (i) five (5),  multiplied  by (ii) the  quotient
obtained  by  dividing  $8.00  by  the  applicable   "Series  B  Market  Factor"
(determined  as  provided  in  Section  5B(ii));  provided,  however,  that  the
Conversion  Rate  shall not  exceed




<PAGE>
______  unless and until the  Shareholder  Approval (as defined  below) has been
obtained.

                  (ii) Series B Market Factor.  The Series B Market Factor shall
mean the  following:  (A) if the Market Price is less than or equal to $3.33-1/3
as of the Adjustment Date, the Series B Market Factor shall equal $3.33-1/3; (B)
if the Market  Price is  greater  than  $3.33-1/3  but less than $8.00 as of the
Adjustment  Date,  the Series B Market Factor shall equal the Market Price;  and
(C) if the Market Price is greater  than or equal to $8.00 as of the  Adjustment
Date,  the Series B Market  Factor shall equal $8.00;  provided,  however,  that
notwithstanding  clauses (A), (B) and (C) of this  Section  5B(ii),  if Series B
Preferred is converted  prior to the  Adjustment  Date (whether by the holder or
automatically   pursuant  to  Section  5F(i)),  or  if  the  Target  Achievement
Percentage  (as defined in the Side Letter) equals zero (0), the Series B Market
Factor shall equal $8.00.

                  (iii)  Adjustment.  The  Series  B  Conversion  Rate  shall be
subject to adjustment pursuant to Section 5C.

                  5C. Adjustment for Stock Splits and Combinations, Common Stock
Dividends and  Distributions.  If the Corporation shall at any time or from time
to time  after  the date of the  initial  issuance  of Series B  Preferred  (the
"Original  Series B Issue Date") effect a subdivision of the outstanding  Common
Stock,  the  Series  B  Conversion  Rate  in  effect   immediately  before  that
subdivision shall be proportionately  increased.  Conversely, if the Corporation
shall at any time or from time to time  after the  Original  Series B Issue Date
combine the outstanding  shares of Common Stock into a smaller number of shares,
the Series B Conversion Rate in effect  immediately before the combination shall
be  proportionately  decreased.  Any  adjustment  under this  Section 5(d) shall
become  effective  at the  close of  business  on the date  the  subdivision  or
combination becomes effective.

                  If the  Corporation at any time or from time to time after the
Original Series B Issue Date makes, or fixes a record date for the determination
of holders of Common Stock entitled to receive,  a divided or other distribution
payable in additional  shares of Common  Stock,  in each such event the Series B
Conversion Rate that is then in effect shall be increased as of the time of such
issuance or, in the event such record date is fixed, as of the close of business
on such record date, by multiplying  the Series B Conversion Rate then in effect
by a fraction (1) the numerator of which is the total number of shares of Common
Stock issued and outstanding  immediately  prior to the time of such issuance or
the close of  business  on such  record date plus the number of shares of Common
Stock  issuable  in  payment  of  such  dividend  or  distribution,  and (2) the
denominator  of which is the total  number of shares of Common  Stock issued and
outstanding  immediately  prior to the  time of such  issuance  or the  close of
business on such record  date;  provided,  however,  that if such record date is
fixed and such dividend is not fully paid or if such  distribution  is not fully
made on the  date  fixed  therefor,  the  Series  B  Conversion  Rate  shall  be
recomputed  accordingly  as of the close of  business  on such  record  date and
thereafter  the Series B




<PAGE>
Conversion  Rate shall be adjusted  pursuant  to this  Section 5C to reflect the
actual payment of such dividend or distribution.

                  5D. Reorganizations, Mergers or Consolidations. If at any time
or from time to time after the Original Series B Issue Date, the Common Stock is
converted   into  other   securities   or  property,   whether   pursuant  to  a
reorganization,    merger,    consolidation   or   otherwise   (other   than   a
recapitalization,   subdivision,  combination,  reclassification,   exchange  or
substitution  of shares  provided for elsewhere in this Section 5), as a part of
such  transaction,  provision  shall be made so that the holders of the Series B
Preferred shall  thereafter be entitled to receive upon conversion of the Series
B Preferred the number of shares of stock or other securities or property of the
Corporation  to  which  a  holder  of the  number  of  shares  of  Common  Stock
deliverable  upon  conversion  would have been entitled in connection  with such
transaction, subject to adjustment in respect of such stock or securities by the
terms thereof.  In any such case,  appropriate  adjustment  shall be made in the
application  of the  provisions  of this Section 5 with respect to the rights of
the holders of Series B  Preferred  after such  transaction  to the end that the
provisions  of this Section 5 (including  adjustment  of the Series B Conversion
Rate then in effect and the number of shares  issuable  upon  conversion  of the
Series B  Preferred)  shall be  applicable  after  that  event  and be as nearly
equivalent  as  practicable.  In the  case  of  any  reorganization,  merger  or
consolidation  in  which  the  Corporation  is not  the  surviving  entity,  the
Corporation  shall not consummate the  transaction  unless the entity  surviving
such transaction assumes all of the Corporation's obligations hereunder.

                  If at any time or from time to time after the Original  Series
B Issue Date,  the Common Stock  issuable  upon the  conversion  of the Series B
Preferred is changed into the same or a different  number of shares of any class
or classes of stock, whether by recapitalization,  reclassification or otherwise
(other  than a  subdivision  or  combination  of shares or stock  dividend  or a
reorganization,  merger or consolidation  provided for elsewhere in this Section
5), in any such event  each  holder of Series B  Preferred  shall have the right
thereafter  to  convert  such  stock into the kind and amount of stock and other
securities  and property  receivable in connection  with such  recapitalization,
reclassification or other change with respect to the maximum number of shares of
Common  Stock  into  which  such  shares of Series B  Preferred  could have been
converted  immediately  prior  to  such  recapitalization,  reclassification  or
change, all subject to further adjustments as provided herein or with respect to
such other securities or property by the terms thereof.

                  5E. Notices.

                  (i) Immediately upon any adjustment of the Series B Conversion
Rate  other than as  contemplated  in Section  5B,  the  Corporation  shall




<PAGE>
give written notice thereof to all holders of Series B Preferred,  setting forth
in reasonable detail and certifying the calculation of such adjustment.

                   (ii) Upon (A) any  taking by the  Corporation  of a record of
the  holders  of any class of  securities  for the  purpose of  determining  the
holders thereof who are entitled to receive any dividend or other  distribution,
or (B) any  reorganization,  any  reclassification  or  recapitalization  of the
capital stock of the Corporation, any merger or consolidation of the Corporation
with or into any other  corporation,  or any Liquidation,  the Corporation shall
mail to each holder of Series B Preferred at least twenty (20) days prior to the
record date specified therein a notice specifying (1) the date on which any such
record is to be taken for the  purpose of such  dividend or  distribution  and a
description  of such  dividend or  distribution,  (2) the date on which any such
reorganization, reclassification, transfer, consolidation, merger or Liquidation
is expected to become  effective,  and (3) the date, if any, that is to be fixed
for determining the holders of record of Common Stock (or other securities) that
shall be entitled to exchange their shares of Common Stock (or other securities)
for  securities  or  other  property   deliverable  upon  such   reorganization,
reclassification, transfer, consolidation, merger or Liquidation.

                  5F.  Automatic  Conversion.  Each share of Series B  Preferred
shall  automatically  be  converted  into shares of Common  Stock,  based on the
then-effective  Series B  Conversion  Rate,  on the earliest to occur of (i) the
first date as of which the Market Price is $8.00 or more for any 15  consecutive
trading days during any period in which Series B Preferred  is  outstanding  and
(ii) the date that is 30 days after the later of the Determination  Date and the
date any required Shareholder Approval is received.

                  5G. Mechanics of Conversion.

                  (i) Optional Conversion. Each holder of Series B Preferred who
desires to convert the same into shares of Common Stock pursuant to this Section
5 shall surrender the certificate or certificates  therefor,  duly endorsed,  at
the office of the  Corporation or any transfer agent for the Series B Preferred,
and shall give written notice to the Corporation at such office that such holder
elects to convert  the same.  Such  notice  shall  state the number of shares of
Series B Preferred being converted.  Thereupon,  the Corporation  shall promptly
issue and deliver at such office to such holder a  certificate  or  certificates
for the number of shares of Common  Stock to which such holder is entitled and a
certificate representing any Series B Preferred shares which were represented by
the certificate or certificates  delivered to the Corporation in connection with
such conversion but which were not converted. Such conversion shall be deemed to
have been made at the close of  business  on the date of such  surrender  of the
certificate  representing the shares of Series B Preferred to be converted,  and
the person  entitled to receive the shares of Common  Stock  issuable  upon such
conversion shall




<PAGE>
be treated for all purposes as the record  holder of such shares of Common Stock
on such date.

                  (ii)  Automatic  Conversion.  Upon the occurrence of the event
specified in Section 5F, the  outstanding  shares of Series B Preferred shall be
converted  into Common  Stock  automatically  without any further  action by the
holders of such shares and  whether or not the  certificates  representing  such
shares are  surrendered  to the  Corporation  or its transfer  agent;  provided,
however,  that the  Corporation  shall not be  obligated  to issue  certificates
evidencing the shares of Common Stock issuable upon such  conversion  unless the
certificates  evidencing such shares of Series B Preferred are either  delivered
to the  Corporation  or its  transfer  agent as  provided  below,  or the holder
notifies the Corporation or its transfer agent that such  certificates have been
lost,  stolen  or  destroyed  and  executes  an  agreement  satisfactory  to the
Corporation  to  indemnify  the  Corporation  from  any loss  incurred  by it in
connection  with  such  certificates.  Upon  surrender  by  any  holder  of  the
certificates formerly representing shares of Series B Preferred at the office of
the Corporation or any transfer agent for the Series B Preferred, there shall be
issued and  delivered to such holder  promptly at such office and in its name as
shown  on  such  surrendered  certificate  or  certificates,  a  certificate  or
certificates  for the number of shares of Common  Stock into which the shares of
Series B  Preferred  surrendered  were  convertible  on the  date on which  such
automatic  conversion  occurred.  Until  surrendered  as  provided  above,  each
certificate  formerly  representing shares of Series B Preferred shall be deemed
for all  corporate  purposes to  represent  the number of shares of Common Stock
resulting from such automatic conversion.

                  5H.  Fractional  Shares.  No fractional shares of Common Stock
shall be issued  upon  conversion  of Series B  Preferred.  All shares of Common
Stock (including  fractions  thereof)  issuable upon conversion of more than one
share of Series B Preferred by a holder thereof shall be aggregated for purposes
of  determination  whether the  conversion  would  result in the issuance of any
fractional share. If, after the aforementioned aggregation, the conversion would
result in the issuance of any fractional  share, the Corporation  shall, in lieu
of issuing any fractional  share, pay cash equal to the product of such fraction
multiplied by the Common  Stock's fair market value (as determined by the Board)
on the date of conversion.  Notwithstanding the foregoing, in the event that any
holder  converts  shares of Series B  Preferred  ten times  within  any one year
period,  the  Corporation  shall not be  obligated  to pay any cash  amount  for
fractional  shares upon any subsequent  conversion(s) by such holder during such
year,  but may withhold the fractional  share(s) and aggregate  such  fractional
share(s) with any additional  fractional share(s) issuable to such holder during
such year, and pay the cash (if any) required by this section for any fractional
shares remaining after such aggregation at the end of such year.





<PAGE>
                  5I.  Reservation of Shares. The Corporation shall at all times
reserve and keep available out of its  authorized but unissued  shares of Common
Stock,  solely for the purpose of issuance upon the  conversion of the shares of
Series B Preferred,  such number of shares of Common Stock as shall from time to
time be sufficient to effect the  conversion  of all  outstanding  shares of the
Series B Preferred. All shares of Common Stock which are so issuable shall, when
issued,  be duly and validly issued,  fully paid and nonassessable and free from
all  taxes,  liens and  charges.  If at any time the  number of  authorized  but
unissued shares of Common Stock shall not be sufficient to effect the conversion
of all then-outstanding  shares of the Series B Preferred,  the Corporation will
take such corporate  action as may, in the opinion of its counsel,  be necessary
to increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purpose.

                  5J. Payment of Taxes.  The issuance of certificates for shares
of Common  Stock upon  conversion  of Series B Preferred  shall be made  without
charge to the holders of such Series B Preferred for any issuance tax in respect
thereof  or other cost  incurred  by the  Corporation  in  connection  with such
conversion and the related issuance of shares of Common Stock, excluding any tax
or other charge  imposed in connection  with any transfer  involved in the issue
and  delivery  of shares of Common  Stock in a name other than that in which the
shares of Series B Preferred so converted were registered.

                  Section 8. Registration of Transfer.

                  The Corporation  shall keep at its principal office a register

                             RESTRICTION ON TRANSFER

THE SECURITIES  REPRESENTED BY THIS WARRANT HAVE NOT BEEN  REGISTERED  UNDER THE
SECURITIES  ACT OF 1933 (THE "ACT") OR APPLICABLE  STATE  SECURITIES  LAWS,  AND
CANNOT BE RESOLD UNLESS  SUBSEQUENTLY  REGISTERED UNDER THE ACT AND SUCH LAWS OR
UNLESS AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.

                                     WARRANT
                      To purchase shares of Common Stock of
                            Executive TeleCard, Ltd.

                 1.  Grant  of  Warrant.  This is to  certify  that,  for  value
received,  ____________________________  (the "Holder") is entitled to purchase,
subject to and in compliance with the provisions of this Warrant, from Executive
TeleCard,  Ltd., a Delaware corporation  ("EXTEL"),  an aggregate of ___________
shares (the  "Initial  Number")  [THE  INITIAL  NUMBERS WILL ADD UP TO 2,500,000
SHARES] of Common Stock (as defined below) of EXTEL,  as the Initial Number will
be adjusted  following the  Adjustment  Date (as defined  below),  at a purchase
price per share equal to $.001 (the "Exercise  Price").  The Initial Number,  as
adjusted,  and the Exercise Price are subject to further  adjustment as provided
below.

                  2. Term.  This  Warrant  may be  exercised,  subject to and in
compliance with the provisions of this Warrant,  in whole or in part at any time
or from time to time during the period commencing on the later of the Adjustment
Date  (provided,  that if the  Determination  Date (as  defined  below)  has not
occurred  by the time the  Holder  seeks to  exercise  this  Warrant,  EXTEL may
postpone  any  exercise  until  the  Determination  Date,  but then  shall  take
appropriate  steps to put the  Holder in the same  economic  position  as if the
Common Stock  issuable upon exercise of this Warrant had been issued on the date
of attempted  exercise and such Common Stock held until the Determination  Date)
and the date Shareholder Approval is received, and ending on the date that is 30
days after the later of the Determination Date and the date Shareholder Approval
is received.

                  3.       Adjustments.

                  (i)   Determination   Date   Adjustment    Formula.   On   the
Determination  Date,  the Initial Number shall be multiplied by (i) the quotient
obtained by dividing  $8.00 by the  applicable  "Market  Factor"  (determined as
provided  below),   multiplied  by  (ii)  the  applicable  "Target   Achievement
Percentage"




<PAGE> 
(as defined in the Side Letter). The Initial Number, as so adjusted, is referred
to herein as the "Adjusted Number."

                  (ii)  Market   Factor.   The  Market  Factor  shall  mean  the
following:  (A) if the Market Price is less than or equal to $3.33-1/3 as of the
Adjustment  Date,  the Market  Factor shall equal  $3.33-1/3;  (B) if the Market
Price is greater than $3.33-1/3 but less than $8.00 as of the  Adjustment  Date,
the Market Factor shall equal the Market  Price;  and (C) if the Market Price is
greater  than or equal to $8.00 as of the  Adjustment  Date,  the Market  Factor
shall equal $8.00; provided,  however, that notwithstanding clauses (A), (B) and
(C) of this Section 3(ii),  if the Market Price (which,  as defined below, is an
average of the Closing  Prices  over a period of 15  consecutive  trading  days)
equals $8.00 or more at any time prior to the Adjustment Date, the Market Factor
shall equal $8.00.

                  (iii)  Adjustment  for Stock Splits and  Combinations,  Common
Stock  Dividends and  Distributions.  If EXTEL shall at any time or from time to
time after the date of the initial issuance of this Warrant (the "Original Issue
Date") effect a subdivision of the outstanding Common Stock, the Adjusted Number
in effect immediately before that subdivision shall be proportionately increased
and the Exercise Price shall be proportionately decreased.  Conversely, if EXTEL
shall at any time or from time to time after the Original Issue Date combine the
outstanding shares of Common Stock into a smaller number of shares, the Adjusted
Number in effect  immediately  before the combination  shall be  proportionately
decreased  and the  Exercise  Price  shall  be  proportionately  increased.  Any
adjustment  under this Section  3(iii)  shall  become  effective at the close of
business on the date the subdivision or combination becomes effective.

                  If EXTEL at any time or from time to time  after the  Original
Issue Date  makes,  or fixes a record date for the  determination  of holders of
Common Stock  entitled to receive,  a divided or other  distribution  payable in
additional  shares of Common  Stock,  in each such event the Adjusted  Number in
effect immediately  before that issuance shall be proportionately  increased and
the  Exercise  Price shall be  proportionately  decreased as of the time of such
issuance or, in the event such record date is fixed, as of the close of business
on such record date,  by  multiplying  the  Adjusted  Number then in effect by a
fraction  (1) the  numerator  of which is the  total  number of shares of Common
Stock issued and outstanding  immediately  prior to the time of such issuance or
the close of  business  on such  record date plus the number of shares of Common
Stock  issuable  in  payment  of  such  dividend  or  distribution,  and (2) the
denominator  of which is the total  number of shares of Common  Stock issued and
outstanding  immediately  prior to the  time of such  issuance  or the  close of
business on such record date,  and by  multiplying  the  Exercise  Price then in
effect by the inverse of such fraction;  provided,  however, that if such record
date is fixed and such dividend is not fully paid or if such distribution is not
fully made on the date fixed  therefor,  the  Adjusted  Number and the  Exercise
Price shall be recomputed accordingly as of the close of business on such record
date 


<PAGE>



and  thereafter  the Adjusted  Number and the  Exercise  Price shall be adjusted
pursuant to this Section  3(iii) to reflect the actual  payment of such dividend
or distribution.

                  (iv)  Reorganizations,  Mergers or  Consolidations.  If at any
time or from time to time after the  Original  Issue Date,  the Common  Stock is
converted   into  other   securities   or  property,   whether   pursuant  to  a
reorganization,    merger,    consolidation   or   otherwise   (other   than   a
recapitalization,   subdivision,  combination,  reclassification,   exchange  or
substitution  of shares  provided for elsewhere in this Section 3), as a part of
such transaction, provision shall be made so that the Holder shall thereafter be
entitled to receive upon  exercise of this Warrant the number of shares of stock
or other  securities  or  property  of EXTEL to which a holder of the  number of
shares of Common Stock  deliverable  upon  exercise  would have been entitled in
connection with such transaction, subject to adjustment in respect of such stock
or securities by the terms  thereof.  In any such case,  appropriate  adjustment
shall  be made in the  application  of the  provisions  of this  Section  3 with
respect to the rights of the Holder after such  transaction  to the end that the
provisions of this Section 3 (including  adjustment  of the Adjusted  Number and
the Exercise  Price then in effect) shall be applicable  after that event and be
as nearly equivalent as practicable.  In the case of any reorganization,  merger
or consolidation in which EXTEL is not the surviving  entity,  EXTEL shall shall
not  consummate the  transaction  unless the entity  surviving such  transaction
assumes all of EXTEL's obligations hereunder.

                  If at any time or from time to time after the  Original  Issue
Date,  the Common  Stock  issuable  upon the exercise of this Warrant is changed
into the same or a different  number of shares of any class or classes of stock,
whether  by  recapitalization,  reclassification  or  otherwise  (other  than  a
subdivision  or  combination  of shares or stock  dividend or a  reorganization,
merger or  consolidation  provided for elsewhere in this Section 3), in any such
event the Holder shall have the right  thereafter  to exercise  this Warrant for
the kind and amount of stock and other  securities  and property  receivable  in
connection  with such  recapitalization,  reclassification  or other change with
respect to the maximum  number of shares of Common Stock for this Warrant  could
have been exercised immediately prior to such recapitalization, reclassification
or change, all subject to further adjustments as provided herein or with respect
to such other securities or property by the terms thereof.

                  (v)      Notices.

                          (I)  Immediately  upon  determination  of the Adjusted
Number,  and any further  adjustment  of the  Adjusted  Number and the  Exercise
Price,  EXTEL shall give written notice thereof to the Holder,  setting forth in
reasonable detail and certifying the calculation of such adjustment.


<PAGE>


                         (II)  Upon (A) any  taking  by EXTEL of a record of the
holders of any class of securities  for the purpose of  determining  the holders
thereof who are entitled to receive any dividend or other  distribution,  or (B)
any  reorganization,  any  reclassification  or  recapitalization of the capital
stock of EXTEL,  any  merger or  consolidation  of EXTEL  with or into any other
corporation, or any Liquidation,  EXTEL shall mail to the Holder at least twenty
(20) days prior to the record date specified therein a notice specifying (1) the
date on which any such record is to be taken for the purpose of such dividend or
distribution and a description of such dividend or distribution, (2) the date on
which any such reorganization, reclassification, transfer, consolidation, merger
or Liquidation is expected to become  effective,  and (3) the date, if any, that
is to be fixed for  determining  the holders of record of Common Stock (or other
securities)  that shall be entitled to exchange their shares of Common Stock (or
other  securities)  for  securities  or other  property  deliverable  upon  such
reorganization,    reclassification,    transfer,   consolidation,   merger   or
Liquidation.

security  means the composite  closing price of the sales of the Common Stock or
such other  security on all  securities  exchanges on which such security may at

been no sale on any such exchange on any day, the average of the highest bid and
lowest  asked  prices of the  Common  Stock or such other  security  on all such
exchanges  at the end of such day,  or, if such  security is not so listed,  the
closing  price (or last price,  if  applicable)  of sales of the Common Stock or

issuable  upon exercise of this Warrant are issued by an entity other than EXTEL

"Common  Stock" shall mean the shares of the security  issuable upon exercise of
this Warrant if such security is issuable in shares,  or shall mean the smallest

                  "Liquidation" means the liquidation, dissolution or winding up
of EXTEL, whether voluntary or involuntary;  provided, however, that neither the
consolidation or merger of EXTEL into or with any other entity or entities,  nor
the  sale  or  transfer  by  EXTEL  of all or any  part of its  assets,  nor the
reduction of the capital stock of EXTEL, shall be deemed to be a Liquidation.

                  "Market  Price" means (i) if the Common Stock is listed on any
securities  exchange,  quoted in the Nasdaq  National  Market,  or quoted in the
over-the-counter  market  throughout the period of 15  consecutive  trading days

                  5. Exercise Procedures. In order to exercise this Warrant, the
Holder  shall send a written  notice of exercise to EXTEL on any business day at
EXTEL's principal office,  addressed to the attention of the Secretary of EXTEL,
which notice shall  specify the number of shares for which this Warrant is being
exercised,  and shall be accompanied by payment in full of the Exercise Price of
the


<PAGE>


shares for which this Warrant is being exercised.  Payment of the Exercise Price
for the shares of EXTEL Common Stock purchased  pursuant to the exercise of this
Warrant shall be made either in cash, by certified check or by wire transfer. If
the person or entity  exercising this Warrant is not the Holder,  such person or
entity shall also deliver, with the notice of exercise, appropriate proof of the
right of such person or entity to exercise this Warrant.  An attempt to exercise
this Warrant  granted  hereunder  other than as set forth above shall be invalid
and of no force and effect.  Promptly after exercise of this Warrant as provided
for  above,  EXTEL  shall  deliver  to the  person  exercising  this  Warrant  a
certificate  or  certificates  for  the  shares  of  EXTEL  Common  Stock  being
purchased.  In the event this Warrant is  exercised  in part only,  EXTEL shall,
upon  surrender  of this  Warrant for  cancellation,  execute and deliver to the
Holder a new  Warrant  of like  tenor  evidencing  the  right of the  Holder  to
purchase  the balance of the shares of EXTEL  Common  Stock  subject to purchase
hereunder.  Such  stock  certificate  or  certificates  shall  be  appropriately
legended to the extent required by federal or state  securities laws. All shares
of EXTEL  Common  Stock  issued  upon  exercise  of this  Warrant  shall be duly
authorized and validly issued, fully paid and nonassessable.

                  6. Transferability. This Warrant may not be transferred by the
Holder in whole or in part without the prior written consent of EXTEL.

                  7. Reservation of Shares. EXTEL shall at all times reserve and
keep available out of its authorized but unissued shares of Common Stock, solely
for the purpose of issuance  upon the exercise of this  Warrant,  such number of
shares of Common  Stock as shall from time to time be  sufficient  to effect the
full exercise of this Warrant.  All shares of Common Stock which are so issuable
shall, when issued, be duly and validly issued, fully paid and nonassessable and
free from all taxes, liens and charges.  If at any time the number of authorized
but  unissued  shares of Common  Stock  shall not be  sufficient  to effect  the
exercise of all  then-outstanding  shares of this Warrant,  EXTEL will take such
corporate action as may, in the opinion of its counsel, be necessary to increase
its authorized  but unissued  shares of Common Stock to such number of shares as
shall be sufficient for such purpose.

                  8.  Fractional  Shares.  No fractional  shares of Common Stock
shall be issued  upon  exercise  of this  Warrant.  All  shares of Common  Stock
(including  fractions  thereof)  issuable  upon more than one  exercise  of this
Warrant by the Holder thereof shall be aggregated for purposes of  determination
whether the exercise would result in the issuance of any fractional  share.  If,
after the aforementioned aggregation,  the exercise would result in the issuance
of any fractional  share,  EXTEL shall, in lieu of issuing any fractional share,
pay cash equal to the product of such fraction  multiplied by the Common Stock's
fair  market  value  (as  determined  by the  Board)  on the  date of  exercise.
Notwithstanding  the  foregoing,  in the event that the Holder seeks to make ten
separate  exercises of this Warrant ten times within any one year period,  EXTEL
shall not be  obligated  to pay 

<PAGE>


any cash amount for fractional  shares upon any  subsequent  exercise(s) by such
holder during such year, but may withhold the fractional  share(s) and aggregate
such fractional  share(s) with any additional  fractional  share(s)  issuable to
such holder during such year, and pay the cash (if any) required by this section
for any fractional  shares  remaining after such  aggregation at the end of such
year.

                  9. General Restrictions.  EXTEL shall not be required to issue
any shares of EXTEL Common Stock under this  Warrant  prior to the  obtaining of
the  Shareholder  Approval or if the issuance of such shares would  constitute a
violation by EXTEL of any provision of any law or regulation of any governmental
authority,  including  without  limitation,  compliance with the registration or
qualification  requirement of applicable  federal and state  securities  laws or
regulations.  If at any time EXTEL shall determine, based upon a written opinion
of securities  counsel,  that the  registration or  qualification  of any shares
subject to this Warrant under any  applicable  state or federal law is necessary
as a condition of, or in connection  with, the issuance of shares,  this Warrant
may  not  be  exercised  in  whole  or  in  part  unless  such  registration  or
qualification  shall have been effected or obtained free of any  conditions  not
reasonably  acceptable  to EXTEL,  and any delay caused  thereby shall in no way
affect the date of termination of this Warrant.  Specifically in connection with
the  Securities  Act of 1933 (as now in effect  or as  hereafter  amended)  (the
"Securities Act"),  unless a registration  statement under the Securities Act is
in effect  with  respect to the  shares of EXTEL  Common  Stock  covered by this
Warrant,  EXTEL shall not be  required to issue such shares  unless the Board of
Directors of EXTEL has received evidence reasonably  satisfactory to it that the
holder of this  Warrant may acquire such shares  pursuant to an  exemption  from
registration  under the Securities Act.  EXTEL's only obligation to register any
securities  covered  hereby  pursuant to the  Securities Act is set forth in the
Merger Agreement.  As to any jurisdiction that expressly imposes the requirement
that this Warrant shall not be exercisable  unless and until the shares of EXTEL
Common  Stock  covered  by this  Warrant  are  registered  or are  subject to an
available  exemption  from  registration,  the exercise of this  Warrant  (under
circumstances  in which  the laws of such  jurisdiction  apply)  shall be deemed
conditioned upon the  effectiveness of such  registration or the availability of
such an exemption.

                  10. Divisibility; Combination. This Warrant may, at the option
of the Holder,  without expense, be divided into or combined with other Warrants
for EXTEL  Common  Stock which carry the same  rights.  Upon  surrender  of this
Warrant  and any such other  Warrant  to EXTEL  together  with a written  notice
signed by the Holder and  specifying the  denominations  for not less than 1,000
shares of EXTEL Common Stock in which new Warrants are to be issued, EXTEL shall
execute and deliver new Warrants,  as requested entitling the Holder to purchase
in the  aggregate  the same number of shares of EXTEL Common  Stock  purchasable
hereunder and under any such other  Warrants.  The term "Warrant" as used herein
includes any Warrant into which this Warrant may be divided or combined.



<PAGE>





                  11.  Applicable  Law.  This  Warrant  shall be governed by and
construed  in  accordance  with the laws of the State of Delaware  except to the
extent federal law may be applicable.

                  12. Payment of Taxes.  The issuance of certificates for shares
of Common Stock upon  exercise of this Warrant  shall be made without  charge to
the Holder for any  issuance  tax in respect  thereof or other cost  incurred by
EXTEL in  connection  with such  exercise and the related  issuance of shares of
Common Stock.

                 IN WITNESS  WHEREOF,  EXTEL has caused this  Warrant to be duly
executed on the day and year set forth below.

                                    [OMITTED]






                                                                  EXHIBIT 99.1




                      EXECUTIVE TELECARD ANNOUNCES SIGNING
                     OF DEFINITIVE AGREEMENT TO COMPLETE THE
                        ACQUISITION OF IDX INTERNATIONAL

Denver,  Colorado, June 17, 1998 - Executive TeleCard, Ltd. (NASDAQ: EXTL) today
announced the signing of a definitive agreement to acquire IDX International,  a
global  IP-based  fax and  telephony  company,  subject  to  Executive  TeleCard
financing and completion of due diligence.  Executive TeleCard will acquire 100%
of the outstanding shares of IDX for stock and cash.

As  previously  announced,  IDX, a privately  held  company  located in Fairfax,
Virginia,  is a fast growing  supplier of IP-based fax and voice  platforms  and
services  on a global  basis.  IDX has  approximately  $6 million of  annualized
revenue. Management of both companies estimates that IDX will double its revenue
by the fourth quarter of 1998.

To acquire IDX,  Executive  TeleCard will issue convertible  preferred stock and
warrants and pay $5,000,000 in cash. The  convertible  preferred  stock converts
into 2,500,000 shares of Executive TeleCard Common Stock at the end of one year,
with a price  guarantee of $8.00 per share at that time if IDX achieves  certain
revenue and cash flow goals.  The warrants are exercisable  only if IDX achieves
revenue and cash flow goals over the next twelve months in addition to the goals
necessary  for the price  guarantee.  Various  levels of  revenue  and cash flow
performance also determine what amount of Executive TeleCard Common Stock (up to
an  additional   2,500,000   Common  Shares)  for  which  the  warrants   become
exercisable.  If IDX achieves all of its goals,  then  Executive  TeleCard  will
acquire $40 million of additional annual revenue with positive cash flow and IDX
shareholders  will receive $5 million and 5,000,000  Common Shares,  adjusted as
appropriate for the price guarantee.

Executive  TeleCard  will  enter into  employment  agreements  with IDX's  Chief
Executive Officer, Hsin Yen; President and Chief Operating Officer,  Jeffey Gee;
and the President of IDX's European subsidiary, Rudy Mattheus. Upon closing, Mr.
Yen and IDX's Chairman, Richard Chiang will be appointed to Executive TeleCard's
Board of Directors.  IDX will be operated as a subsidiary on a day-to-day  basis
by IDX's current senior  management under the direction of Executive  TeleCard's
CEO.
