EXHIBIT 2.3

                 AMENDMENT NO. 2 TO AGREEMENT AND PLAN OF MERGER

          THIS  AMENDMENT  NO. 2 TO AGREEMENT AND PLAN OF MERGER is entered into
as of  October  ___,  1998 by and among  EXECUTIVE  TELECARD,  LTD.,  a Delaware
corporation ("Buyer"), EXTEL Merger Sub. No. 1, Inc., a Virginia corporation and
a wholly-owned  subsidiary of Buyer ("Merger Sub"), IDX  INTERNATIONAL,  INC., a
Virginia  corporation  (the "Company"),  and each of the Company's  stockholders
listed on the signature pages hereto (the "Stockholders").

          WHEREAS,  Buyer, Merger Sub, the Company and the Stockholders  entered
into an Agreement and Plan of Merger dated June __, 1998, which was subsequently
amended on August 27, 1998  pursuant to a certain  Consent  and  Extension  (the
"Merger Agreement"); and

          WHEREAS,  the parties desire to make certain  amendments to the Merger
Agreement.

          NOW THEREFORE, the parties hereto do hereby agree as follows:

          1.  Section  2.1(a) of the Merger  Agreement  shall be replaced in its
entirety so as to read as follows:

          "(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 $.001 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
DOLLARS  ($5,000,000) in the form of convertible  promissory notes (as described
in more detail below)  decreased by the amount of the Closing  Indebtedness  (as
defined in Section  2.4) and any other  amounts  to be  deducted  from the notes
portion of the Purchase Price as provided herein, including Section 12.11 hereof
(collectively,  the "Notes Portion"). The net







amount  determined  pursuant  to this  clause,  including  both  stock and notes
portions,  is referred to as the ("Purchase Price").  The Notes Portion shall be
evidenced by three (3) convertible  subordinated  promissory  notes of Buyer, in
the  respective  forms  attached  hereto as Exhibits D1, 2, and 3 (the "Notes"),
which by their terms are  convertible  into Acquiror  Common Stock under certain
circumstances.  The Purchase Price shall be allocated among the  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 Notes  Portion made payable to the  Representative  (as
hereinafter  defined) for the benefit of the Stockholders,  to be distributed to
the Stockholders by the Representative in such proportions  following payment or
conversion  into Acquiror  Common Stock.  All such shares of Company Stock shall
cease to be  outstanding  and shall  automatically  be canceled  and retired and
shall cease to exist, and each certificate previously evidencing any such shares
shall  thereafter  represent  only the right to receive  the shares of  Acquiror
Convertible  Preferred  Stock,  Acquiror  Warrants and the proceeds of the Notes
(whether cash or Acquiror  Common Stock,  when paid or issued)  pursuant to this
Section  2.1(a) and the cash payable in lieu of  fractional  shares  pursuant to
Section 2.1(e). The holders of certificates previously evidencing such shares of
Company Stock outstanding immediately prior to the Effective Time shall cease 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
for  certificates  evidencing  the  appropriate  number of  shares  of  Acquiror
Convertible  Preferred  Stock,  Acquiror  Warrants to purchase  the  appropriate
number  of  shares  of  Acquiror  Common  Stock  and the  right to  receive  the
appropriate  portion of the  proceeds  of the Notes  (whether  cash or  Acquiror
Common  Stock,  when  paid or  issued)  as set  forth on  Schedule  2.1 upon the
surrender of such certificate as provided in Section 2.2."

          2.  Section  2.4 of the  Merger  Agreement  shall be  replaced  in its
entirety so as to read as follows:

          "Immediately  prior to the Effective Time,  Acquiror shall cause to be
paid  all  principal  and  accrued  interest   outstanding  under  any  debt  to
stockholders  ("Stockholder  Debt"). The sum of (x) the Stockholder Debt and (y)
(I) the net  collectible  accounts  receivable of the Company (on a consolidated
basis) as of the  Closing  Date,  net of  accounts  payable of the Company (on a
consolidated basis) as of the Closing Date (all as determined in accordance with
generally accepted accounting principles  consistently  applied),  less (II) all
accrued but
        



unpaid  dividends as of the Closing Date, is referred to herein  collectively as
the "Closing Indebtedness". Any principal and interest outstanding under various
Loan Agreements between Acquiror and the Company and various Promissory Notes of
the Company in favor of Acquiror of the same date,  including without limitation
the Second Bridge Loan (as defined in Section 8.15) shall not constitute Closing
Indebtedness  for purposes of this  Agreement.  Payment of Closing  Indebtedness
owed to any creditor  other than  Acquiror  shall be made in  accordance  with a
written  payoff  letter  from the holder of the Closing  Indebtedness  in a form
reasonably acceptable to Acquiror."

          3. Section  2.1(e)  shall be  renumbered  as Section  2.1(f) and a new
Section  2.1(e)  shall be included in the Merger  Agreement  which shall read as
follows:

          "(e) Fractional Shares. The Acquiror shall not be obligated to deliver
to the Stockholders any fractional share of Acquiror Convertible Preferred Stock
or Acquiror Common Stock upon conversion of Acquiror Convertible Preferred Stock
or Acquiror Warrants,  but in lieu thereof may at its option make a cash payment
in respect thereof in any manner  permitted by law equal to the Market Price (as
defined in Exhibit A hereto) of the Acquiror Common Stock or, in the case of the
Acquiror  Preferred  Stock,  the  Acquiror  Common Stock into which the Acquiror
Preferred Stock is convertible.  All shares of Common Stock (including fractions
thereof)  issuable  under this  Agreement  shall be  aggregated  for purposes of
determination  whether  the  issuance  would  result  in  the  issuance  of  any
fractional shares."

          4. Section  8.13(g) shall be  renumbered as Section  8.13(h) and a new
Section  8.13(g) shall be included in the Merger  Agreement  which shall read as
follows:

          "(g) Receive the  proceeds of the Notes and  allocate  and  distribute
such proceeds as provided in Section  2.1(a) of the Merger  Agreement and in the
Notes. Nothing in this Agreement shall give rise to any liability on the part of
Representative  for any mistakes that may occur in making such  allocations  and
distributions  so long as  Representative,  has acted in good faith and  without
willful misconduct or fraud."

          5. All  references  in the Merger  Agreement  to a cash portion of the
Purchase  Price  shall be deemed to refer  instead  to the  Notes  Portion.  All
references in the Merger Agreement to payment of cash by Acquiror as part






of the  Purchase  Price shall be deemed to refer  instead to the proceeds of the
Notes (whether cash or Acquiror Common Stock, when paid or issued).

          6. Capitalized terms used herein and not defined herein shall have the
meaning ascribed to them in the Merger Agreement. All other terms and provisions
of the Merger  Agreement  shall  continue in full force and effect and unchanged
and are hereby confirmed in all respects.

          7. This  Amendment  No. 2 to the  Agreement  and Plan of Merger may be
executed in several counterparts, each of which is an original, but all of which
together constitute one and the same agreement. The descriptive headings in this
Amendment  No. 2 to the  Agreement  and Plan of Merger  are for  convenience  of
reference only and shall not define or limit the provisions hereof.

          8. This  Amendment  No. 2 to Agreement  and Plan of Merger is governed
by,  and  shall be  construed  in  accordance  with,  the  laws of the  State of
Virginia.


                  [Remainder of Page Intentionally Left Blank]






          IN WITNESS WHEREOF,  the parties have executed this Amendment No. 2 to
the Agreement and Plan of Merger on and as of the date first set forth above.
