                    Amendment No. 1 to Stock Purchase Agreement 

          Gentlemen:

               Reference is made to the Stock Purchase Agreement,
          dated as of July 25, 1997, by and among General Cinema
          International, Inc., United Artists Theatre Circuit,
          Inc., Fondo Optima, S.A. de C.V. and others (the
          "Agreement").  Capitalized terms used herein, unless
          otherwise defined herein, shall have the meaning given
          them in the Agreement.

               By our letter dated July 25, 1997 (the "July 25
          Letter"), we provided notice of objection under Section
          7.4 and Schedule 7.4 of the Agreement with respect to
          certain matters.  We also refer to our letter dated
          August 8, 1997 (the "August 8 Letter"), in which we have
          raised certain concerns in connection with certain other
          matters.

               This confirms the Parties' agreement as follows:

               1.   Pursuant to Section 7.4 of the Agreement and
          notwithstanding our having sent the July 25 Letter and
          the August 8 Letter, the Parties ratify and confirm in
          all respects the continued effectiveness of the
          Agreement, as amended hereby.

               2.   Section 3.1 of the Agreement "Time and Place of
          Closing" be amended and restated in its entirety as
          follows:

                    "3.1  Time and Place of Closing.  Upon the
          terms of, and subject to the satisfaction (or waiver
          pursuant to Section 14.9 hereof) of the conditions
          contained in this Agreement, the closing (the "Closing")
          of the transactions  contemplated by this Agreement (1)
          relating to the Mexican Shares will take place at the
          offices of White & Case, S.C., Torre Optima, Paseo de la
          Palmas 405-6 Piso, Col. Lomas de Chapultepec, 11000
          Mexico, D.F.; (2) relating to the CUAA Shares will take
          place at the offices of Munoz De Toro & Munoz De Toro,
          Alicia Moreau De Justo, Loft 212, Puerto Madero, 1107 -
          Buenos Aires, Argentina; and (3) in all other respects at
          the offices of Skadden, Arps, Slate, Meagher & Flom LLP
          at 919 Third Avenue, New York, NY, or at such other place
          as the parties may mutually agree, simultaneously on
          September 26, 1997 (the "Closing Date")." 

               3.   The Parties hereby agree that all references in
          the Agreement to August 22, 1997 or to the "Closing Date"
          shall in each case be deemed to be references to
          September 26, 1997.

               4.   Pursuant to Section 14.1(b) of the Agreement,
          the Parties hereby agree and confirm that they shall
          treat the Agreement as relating to the sale of the CUAA
          Shares and the Mexican Shares only and to close such
          sales, subject to the terms and conditions of the
          Agreement as amended hereby, without regard to the
          provisions of the Agreement relating to the UATC Shares.

               5.   References to "October 31, 1997" in Section
          12.1 of the Agreement are hereby amended to "December 31,
          1997."

               6.   Schedule 6.1(c) is hereby amended as attached.

               7.   Pursuant to Section 2.3 of the Agreement, the
          Buyer has elected to acquire from UA Mexico the accounts
          receivable owned by UA Mexico and due from Cinemas, and
          in connection therewith, UA agrees that it shall cause UA
          Mexico to execute and deliver any and all documents
          necessary to effectuate such transfer; provided, however,
          that UA Mexico shall and hereby does retain for itself an
          amount of such receivable equal to fifty percent (50%) of
          the Cinemas VAT Intercompany Receivable, which UA
          acknowledges shall be payable only to the extent of fifty
          percent (50%) of the Construction Program VAT Refund as
          such amount is paid to Cinemas.

               8.   The Parties hereby agree that the purchase
          price for the CUAA Shares shall be adjusted as provided
          in Schedule 8 attached hereto.

               Your agreement and acceptance of the foregoing is
          signified by your signatures below.  Please sign and
          return to us one of the enclosed copies of this letter
          (as well as the attached confirmation of guarantees,
          where appropriate), which shall thereupon become a
          binding Amendment No. 1 to the Agreement.
