      the Shares’ sales price as set forth in Section Three of the Stock

              WHEREAS,
      the Parties wish to change the price set forth in Section Three of the
      Stock Purchase Agreement, in order to include the Additional Shares and

      result of the Residual Interests Acquisition

 Section
Three of the Stock Purchase Agreement shall be amended and replaced in full by
the following text:
 
 “Three: Price.
 
 The sales
price of the Shares, i.e. for an amount of 787,697 Shares, is
US$ 56,041,216 (fifty-six million forty-one thousand two hundred and
sixteen U.S. dollars) (the “Price of the Shares ”) and the sales price of the
Additional Shares acquired by DATACORP from the Company’s minority shareholders,
i.e. for an amount of 14,948 Shares, is US$ 1,063,485(one million
sixty-three thousand four hundred and eighty-five U.S. dollars) (the “Price of
the Additional Shares” and together with the Price of the Shares, the
“Price”).
 
 Notwithstanding
the foregoing, the Price of the Additional Shares may be reviewed, in the event
that the Argentine Securities Commission does not approve the amount initially
tendered by DATACORP under the Residual Interests Acquisition Process, taking as
Price such amount as is finally approved by the Argentine Securities Commission.
For purposes of converting the amount that is finally approved to U.S. dollars,
the average between the buying and selling ARS/USD exchange rate prevailing two
business days before the Closing Date shall be taken into account.
 
 The Price
shall be valid since the date of this Agreement until three months after the
conclusion of the Residual Interests Acquisition Process, even if the Residual
Interests Acquisition Process ends without the minority shareholders’ shares
having been acquired
  4
  (the
“Price Validity Term”).
 
 The Price
shall be paid by TASA to DATACORP on the Closing Date.
 
 Payment
shall be made in such account as designated by DATACORP in writing, and
crediting of such transfer shall be regarded as sufficient receipt
thereof.
 
 The
Parties agree to negotiate in good faith any adjustments to the Price that may
be necessary in case that, Condition Precedent 1.2 (f) having been satisfied and
the Price Validity Term having elapsed, the SECOM’s Consent contemplated in
Condition Precedent 1.2 (d) shall have not been obtained.
 
 FIVE
 
 This
“Second Amendment” shall form a sole and single agreement together with the
Stock Purchase Agreement and its First Amendment, so that any reference to the
Stock Purchase Agreement, unless otherwise expressly set forth, shall be deemed
to refer to the Stock Purchase Agreement as amended by this “Second
Amendment”.
  SIX
 
 All the
terms and conditions of this Stock Purchase Agreement not expressly amended by
this Second Amendment or the First Amendment shall remain in full force and
effect.
  SEVEN
 
 Sections
Ten and Eleven of the Stock Purchase Agreement shall apply mutatis mutandis to this
Second Amendment to the Stock Purchase Agreement.
 
  In witness
whereof, 2 (two) identical counterparts are signed on this 28th day of March,
2008.
