          FOR VALUE RECEIVED,  Executive TeleCard,  Ltd., a Delaware corporation

          This Note is issued  pursuant to and in accordance  with the terms and
conditions  of the  Agreement  and Plan of Merger,  dated June 10,  1998,  among
Maker,  Extel  Merger Sub No. 1, the  Company and the  Stockholders  (as defined
therein),  which was  subsequently  amended on August  27,  1998  pursuant  to a
certain  Consent and  Extension and amended again on October , 1998 by Amendment
No. 2 to Agreement and Plan of Merger (the "Merger  Agreement"),  and is subject
to the  terms  and  conditions  of the  Merger  Agreement,  which  are,  by this
reference,  incorporated herein and made a part hereof,  including  particularly
the provisions  regarding the authority of Payee as the  Representative  and the
allocation  of the  amounts  payable  (or stock  issuable)  hereunder  among the
Stockholders.  Capitalized  terms  used in this  Note  which  are not  otherwise
defined  herein  shall  have the  respective  meanings  set forth in the  Merger
Agreement.

          The outstanding  principal amount of this Note, together with interest
accrued thereon as provided herein (the "Maturity Amount") shall be due and







payable in full on the  Maturity  Date,  or such earlier date on which this Note
may become due following an Event of Default (as defined below).

          All payments of  principal  and interest on this Note shall be made by
check or wire transfer of immediately available funds to an account specified by
Payee in written instructions to Maker at least three (3) business days prior to
the Maturity  Date.  If any payment of principal or interest on this Note is due
on a day which is not a  Business  Day,  such  payment  shall be due on the next
succeeding  Business Day, and such extension of time shall be taken into account
in calculating  the amount of interest  payable under this Note.  "Business Day"
means any day other than Saturday, Sunday or a legal holiday in the Commonwealth
of Virginia.

          Maker may,  without  premium or penalty,  at any time and from time to
time,  prepay all or any portion of the outstanding  principal balance due under
this Note.

          The occurrence of any one of more the following events with respect to
Maker shall constitute an event of default hereunder ("Event of Default"):

          (a) If Maker  shall fail to pay when due any payment of  principal  or
interest on this Note and such failure  continues  for ten  Business  Days after
Payee notifies Maker in writing of such Event of Default.

          (b) If,  pursuant  to or  within  the  meaning  of the  United  States
Bankruptcy  Code or any other  federal or state law  relating to  insolvency  or
relief of debtors (a  "Bankruptcy  Law"),  Maker shall (i)  commence a voluntary
case or proceeding;  (ii) consent to the entry of an order for relief against it
in an involuntary case; (iii) consent to the appointment of a trustee, receiver,
assignee,  liquidator  or  similar  official;  (iv) make an  assignment  for the
benefit of its creditors;  or (v) admit in writing is inability to pay its debts
as they become due.

          (c) If a court of  competent  jurisdiction  enters  an order or decree
under any  Bankruptcy Law that (i) is for relief against Maker in an involuntary
case,  (ii)  appoints  a  trustee,  receiver,  assignee,  liquidator  or similar
official for Maker or substantially all of Maker's  properties,  or (iii) orders
the liquidation of Maker,  and in each case the order or decree is not dismissed
within 120 days.

          Upon the occurrence of any such Event of Default,  Maker,  in its sole
and absolute option,  may convert (the "Conversion") all or any part of the then
outstanding  principal  and  accrued  but unpaid  interest  under this Note into
shares of its Common Stock, par value $.001 ("Maker Common Stock"),  as provided
below,  which Conversion shall constitute payment in full of the amount being so
converted (the "Converted Amount").  Maker may effect such Conversion by written
notice to Payee  (pursuant to the  applicable  notice  provisions  of the Merger
Agreement), at any time or from time to time until the outstanding principal and
accrued  but  unpaid  interest  under  this Note has been  paid in full,  of the
Maker's  election to







effect the Conversion and the portion of the  outstanding  principal and accrued
but unpaid interest being converted.  Upon receipt of such notice by Payee, such
Conversion shall be deemed  effective,  and the Converted Amount shall be deemed
converted  into the right to receive the number of shares of Maker  Common Stock
equal to the  Converted  Amount  divided  by the  Closing  Price (as  defined in
Exhibit A to the Merger Agreement) on the date of the occurrence of the Event of
Default.

          Should an Event of Default  exist and be  continuing  for ten Business
Days  (unless  Maker has paid the then  outstanding  principal  and  accrued but
unpaid interest under this Note or given notice of Conversion as provided herein
of the entire amount then due and payable),  (x) simple interest shall accrue on
the  outstanding  principal  balance of this Note from the date of such Event of
Default at the rate of LIBOR plus 400 basis points  ("Default  Interest")  until
the  outstanding  principal and accrued but unpaid  interest under this Note has
been paid (or Maker has given  notice of  Conversion  as provided  herein of the
entire amount then due and payable),  and (y) (in the case of the first Event of
Default to exist and be continuing for such period) Maker shall issue Payee,  as
Representative  of the  Stockholders,  a  warrant,  substantially  in  the  form
attached  hereto as Appendix A ("Default  Warrant"),  to purchase such number of
shares of Common Stock as is equal to ten percent (10%) of the then  outstanding
principal  and  accrued  but  unpaid  interest  under  this Note  divided by the
exercise  price of the Default  Warrants,  which shall equal  Closing  Price (as
defined in Exhibit A to the Merger  Agreement) on the date of the  occurrence of
such Event of Default.

          Presentment, demand, protest and all other notices of any kind from or
to be given by Payee are hereby expressly waived.

          Amounts  payable by Maker  (including  Maker  Common Stock and Default
Warrants  that may be  issued)  hereunder  shall be  received  by Payee  for the
benefit of the Stockholders  solely in Payee's capacity as Representative of the
Stockholders,  and shall be allocated among the  Stockholders in accordance with
the  Stockholder  Percentages  as  provided  in  the  Merger  Agreement,  to  be
distributed  to the  Stockholders  by the  Representative  in  such  proportions
following each payment or Conversion  hereunder.  Maker shall use all reasonable
efforts to assist Payee in making such  allocations and  distributions.  Nothing
herein  shall give rise to any  liability  on the part of Payee or Maker for any
mistakes that may occur in making such allocations and  distributions so long as
Payee or Maker,  respectively,  has  acted in good  faith  and  without  willful
misconduct or fraud.

          Notwithstanding  anything else to the contrary herein, Maker shall not
effect any Conversion or issue any Default  Warrants to the extent,  but only to
the  extent  (and  notice of  Conversion  shall be deemed  revised to the extent
necessary  to permit  Maker to  comply  with this  sentence),  that  Shareholder
Approval (as defined in Exhibit A to the Merger Agreement) would be required for
such  Conversion  or such  issuance  (taken  together with any issuance of Maker
stock under the Merger






Agreement or required hereby which would be considered  under  applicable  rules
and  regulations  together with such  Conversion or such issuance in determining
whether  Shareholder  Approval is required),  unless and until such  Shareholder
Approval has been obtained.

          This Note shall be governed by, and construed in accordance  with, the
laws of the  State of  Virginia,  regardless  of the laws that  might  otherwise
govern under applicable principles of conflicts of law.

          Whenever used herein, the words "Maker" and "Payee" shall be deemed to
include their respective successors and assigns.

          IN WITNESS  WHEREOF,  the  undersigned has duly executed this Note, or
has caused this Note to be duly  executed on its behalf,  as of the day and year
first hereinabove set forth.

issuance in determining 








whether  Shareholder  Approval is required),  unless and until such  Shareholder
Approval has been obtained.
