                            OPTION TO PURCHASE STOCK
                            ------------------------

            THIS  AGREEMENT  ENTERED  INTO  this ________________________ by and
between _______________________________________ (the "Seller" ), with a business
address at ___________________________________________,  and NYFIX  CORPORATION,
(the  "Purchaser"),  a Delaware  Corporation  with its  principal  office at 333

the present  holders of such  Common  Stock with the  Company  having  1,200,000

800,000 shares to be issued for the  conversion of the Series A Preferred  Stock
for a total of 2,000,000 shares authorized or to be authorized; and

            WHEREAS,  the Seller is the owner of _______  Shares of Common Stock
of Euro Link Network,  Inc.,  subject to certain conditions which are summarized

            WHEREAS,  the Seller is desirous of granting such option to purchase
a fixed amount of such Shares and Purchaser is desirous to obtain such option to
purchase a fixed amount of such Shares upon the terms and conditions  herein set
forth,

            WHEREAS,  Seller has  consented  to a share  reissuance  by Eurolink
Network,  Inc.  and Seller and  Purchaser  agree to this  Revised  Agreement  to
include the new shares issued to Seller,

            NOW, THEREFORE,

            IN  CONSIDERATION  of Ten Dollars  ($10.00) paid in hand,  and other
good and valuable consideration,  the receipt and sufficiency of which is hereby
acknowledged, the parties agree as follows:

            1.  GRANT  OF  OPTION.  Seller  hereby  grant to  Purchaser,  or its
designee  or  assign,  an option  to  purchase,  upon the  terms and  conditions
hereinafter  set forth,  _______  Shares  ("Shares") of the Common Stock of Euro
Link Network, Inc., a Delaware Corporation ("the Company"),  at a purchase price
which shall be the greater of the following:

                (i) At a  price-per-share  computed for the entire  Company on a
            per   share   basis   which   shall  be  equal  to  ten   times  the
            earnings-per-share for the preceding fiscal year prior to the timely
            option  notice,  as  shall  be  determined  by  generally   accepted
            accounting practices consistently applied. In computing the earnings
            per share,  all monies  paid by the  Company  prior to April 1, 2002
            related to establishment,  organizational  and licensing costs shall
            not  be  deducted  or  adversely  considered  in  any  manner  which
            diminishes the earnings per share price  including any  depreciation
            on capital  investments made prior to April 1, 2002. The exercise of
            this Option, divided by the number of shares then outstanding,  with
            a maximum purchase price of $12.50 per Share; or

                (ii) At a minimum price-per-share of $1.25.

                (iii) In no event shall the minimum  purchase price be less than
            US$1,000,000  for all of the shares for which the  Purchaser  has an
            option of the Company under Paragraph 2.

            2. TIME FOR  EXERCISE  OF OPTION.  The option  may be  exercised  by
Purchaser in whole or in part at any time on or after April 1, 2004 and prior to
June 30, 2004. In the event that audited financial statements of the Company are
not provided to Purchaser by April 1, 2004,  the option period shall be extended
to such date as shall be ninety (90) days  following the receipt by Purchaser of
such audited financial statements.

            3.  INTERIM  NON-CASH  DIVIDEND.  If  dividends  are declared on the
common  shares  of the  Company,  payable  other  than in  cash,  such  non-cash
dividends  attributable to each such common share shall be transferred by Seller
to Purchaser upon the exercise of his option, without extra costs.

            4. ADJUSTMENT OF OPTION SHARES. If the outstanding  common shares of
The Company  are changed  into or  exchanged  for a different  number or kind of
shares or other  securities  of The Company or of another  corporation,  whether
through reorganization, recapitalization, shares split up, combination of sales,
merger or consolidation, there shall be substituted for each common share of The
Company  then  subject  to this  option  the number and kinds of shares of other
securities  which each such  outstanding  common share is so changed or for each

such share as exchanged.  Thereafter,  the words "common  shares of The Company"
shall mean such  substituted  shares or other securities and the option price as
set forth in Paragraph (1) above  shall  apply to and be the option  price for a
the shares or other  securities  substitute  for each such  common  share of The
Company

            5. ADDITIONAL OPTION RIGHTS. Seller hereby grants to Purchaser,  for
a  period  of  five  (5)  years  from  the  date of this  Agreement,  an  option
constituting  a right of first  refusal to  purchase  any shares of The  Company
owned by the Seller  and not  subject  to  purchase  by  Purchaser  pursuant  to
Paragraph 1 of this Agreement, at a per share price equal to valuing 100% of the
Company and then  allocating  the 100% purchase price on a per share basis as to
the total number of shares of common stock of the Company then  outstanding with
the price per share equal to "____" shall be 10 times the earnings per share for
the  preceding 12 month  period as shall be  determined  by  generally  accepted
accounting  principles  consistently  applied.  In the event Purchaser elects to
exercise  such option,  Purchaser  shall have ten (10)  business days after such
notice is given by Seller  within which to notify the Seller that the  Purchaser
is exercising such an option and is delivering,  as provided in paragraph 8, the
funds and NYFIX shares  required for the purchase which the Purchaser shall have
elected to make.  If such notice and payment are  received by the Seller  within
said ten (10) day period,  the Seller,  in addition to delivery to the Purchaser
of the Company  shares so purchased by it,  shall  assign to the  Purchaser  the
rights  attributable  to such  shares.  The closing date for the exercise of the
option  shall be no later  than 20 days  from  the date of the  option  exercise
notice or notice of right of first refusal. If, however, the Purchaser shall not
so notify the Seller and pay such purchase  price,  the Seller shall be released
from any further obligation to the Purchaser in respect of such rights and shall
be free to sell such  shares of the  Company  to any person for any price in the
sole discretion of Seller.

            6. RESTRICTIONS ON TRANSFER;  REVERSION. Seller agrees that prior to
expiration date of the Option as set forth herein,  no Shares of Common Stock of
the Company  owned by Seller,  and whether or not subject to the Option,  may be
sold, encumbered,  hypothecated or otherwise transferred without the approval of
the Board of  Directors  of The  Company.  In the event that Seller  voluntarily
leaves the  employment of the Company or is  terminated  for cause except due to
death or major health  concerns as determined  in the sole  discretion of and by
the Company Board of Directors.,  it is agreed and understood that the Shares of
the Company  issued to Seller shall  revert to the Company,  and shall either be
held by the Company in treasury or  redistributed to employees of the Company in
the sole  discretion  of the Board of  Directors.  In the case of death or major
health approved by the Company Board of Directors,  the successor in interest to
the Seller or designated  representative  shall be subject to the same terms and
conditions as all other Sellers of Company Shares.

            7. RESTRICTIONS ON CORPORATE ACTION. Except as provided in Paragraph
6 amoung existing  Shareholders of the Company,  The Seller agrees that prior to
June 30,  2004 the  Company  will not  issue  additional  Shares  of  Common  or
Preferred Stock, Warrants, or Options, nor sell or transfer any Shares of Common
Stock  between or among the  shareholders  of the  Company,  without the written
consent  of  holders  of a  majority  of the  issued  and  outstanding  Series A
Convertible Stock and the Board of Directors of the Company.

            8. RIGHT OF FIRST REFUSAL.  (a) In the event that Purchaser does not
exercise  its option,  it has granted the Company the right of first  refusal to
acquire any Shares of Common Stock of the Company owned by the Purchaser.

               (b) In the event  that  Purchaser  does  exercise  its option and
subsequently  sells its  controlling  interest  in the  Company,  it agrees that
Seller  shall  have  the  right to sell all or part of  Seller's  shares  of the
Company on the same per share  price/benefit  as  Purchaser  with respect to any
Shares of Common Stock of the Company  owned by Seller on the date of such sale,
but that Seller shall not be required to participate in any such sale.

            9. TIME OF PAYMENT FOR SHARES. At the election of the Seller,  which
