      hundred and twenty (120) days after the Issue Date, a Registration
      Statement (the "Initial Shelf Registration Statement") for an offering to

<PAGE>

      Notice and Questionnaires and permitted by the form of Notice and
      Questionnaire included in the Offering Memorandum; provided, however, that
      in no event shall such methods of distribution take the form of an
      underwritten offering of Registrable Securities without the Company's
      prior written consent, which the Company may withhold in its sole
      discretion. The Company shall use its reasonable best efforts to (i) cause
      the Initial Shelf Registration Statement to become effective under the
      Securities Act as promptly as reasonably practicable but in any event by
      the date (the "Effectiveness Deadline Date") that is one hundred eighty
      (180) days after the Issue Date and (ii) (except to the extent permitted
      under Section 3(i) hereof) keep the Initial Shelf Registration Statement
      (and any Subsequent Shelf Registration Statement) continuously effective
      under the Securities Act until the expiration of the Effectiveness Period.
      At the time the Initial Shelf Registration Statement becomes effective
      under the Securities Act, each Holder that became a Notice Holder on or
      before the fifth (5th) Business Day before the date of such effectiveness
      shall be named as a selling securityholder in the Initial Shelf
      Registration Statement and the related Prospectus in a manner that,
      assuming the accuracy of the information in such Notice Holder's Notice
      and Questionnaire, permits such Notice Holder to deliver such Prospectus
      to purchasers of Registrable Securities in accordance with the Securities
      Act.

            (b) If any Shelf Registration Statement ceases to be effective under
      the Securities Act for any reason (except to the extent permitted under
      Section 3(i) hereof) at any time during the Effectiveness Period, the
      Company shall use its reasonable best efforts to promptly cause such Shelf
      Registration Statement to become effective under the Securities Act
      (including obtaining the prompt withdrawal of any order suspending the
      effectiveness of such Shelf Registration Statement), and in any event
      shall, within thirty (30) days of such cessation of effectiveness, (i)
      amend such Shelf Registration Statement in a manner reasonably expected to
      obtain the withdrawal of any order suspending the effectiveness of such
      Shelf Registration Statement or (ii) file an additional Registration
      Statement (a "Subsequent Shelf Registration Statement") for an offering to
      be made on a delayed or continuous basis pursuant to Rule 415 of the
      Securities Act registering the resale from time to time by Holders thereof
      of all securities that are Registrable Securities as of the time of such
      filing (or, if registration of Registrable Securities not held by Notice
      Holders is not permitted by the rules and regulations of the SEC, then
      registering the resale from time to time by Notice Holders of their
      securities that are Registrable Securities as of the time of such filing).
      If a Subsequent Shelf Registration Statement is filed, the Company shall
      use its reasonable best efforts to (A) cause such Subsequent Shelf
      Registration Statement to become effective under the Securities Act as
      promptly as practicable after such filing, but in no event later than the
      Subsequent Shelf Registration Statement Effectiveness Deadline Date and
      (B) except to the extent permitted under Section 3(i) hereof, keep such
      Subsequent Shelf Registration Statement (or another Subsequent Shelf
      Registration Statement) continuously effective until the end of the
      Effectiveness Period. Any such Subsequent Shelf Registration Statement
      shall be on Form S-1 or Form S-3 or another appropriate form and shall
      provide for the registration of such Registrable Securities for resale by
      such Holders in accordance with the methods of distribution indicated in
      their Notice and Questionnaires and permitted by the form of Notice and
      Questionnaire included in the Offering Memorandum; provided, however,

                                       -6-

<PAGE>

      that in no event shall such methods of distribution take the form of an
      underwritten offering of Registrable Securities without the Company's
      prior written consent, which the Company may withhold in its sole
      discretion.

            (c) The Company shall supplement and amend any Shelf Registration
      Statement if required by the rules, regulations or instructions applicable
      to the registration form used by the Company for such Shelf Registration
      Statement, if required by the Securities Act or as reasonably requested by
      the Initial Purchasers.

            (d)

                  (i) Each Holder of Registrable Securities agrees that, if such
            Holder wishes to sell Registrable Securities pursuant to a Shelf
            Registration Statement and related Prospectus, it will do so only in
            accordance with this Section 2(d) and Section 3(i). Each Holder of
            Registrable Securities wishing to sell Registrable Securities
            pursuant to a Shelf Registration Statement and related Prospectus
            agrees to deliver a completed and executed Notice and Questionnaire
            to the Company prior to any attempted or actual distribution of
            Registrable Securities under a Shelf Registration Statement. If a
            Holder becomes a Notice Holder after the fifth (5th) Business Day
            before the date the Initial Shelf Registration Statement becomes
            effective under the Securities Act, the Company shall, as promptly
            as reasonably practicable after the date such Holder became a Notice
            Holder, and in any event, subject to clauses (A), (B) and (D) below,
            within five (5) Business Days after such date,

                        (A) if required by applicable law, file with the SEC a
                  supplement to the related Prospectus or a post-effective
                  amendment to the Shelf Registration Statement or file with the
                  SEC a Subsequent Shelf Registration Statement and any
                  necessary supplement or amendment to any document incorporated
                  therein by reference and file any other required document with
                  the SEC so that such Notice Holder is named as a selling
                  securityholder in a Shelf Registration Statement and the
                  related Prospectus in such a manner as to permit such Notice
                  Holder to deliver a Prospectus to purchasers of the
                  Registrable Securities in accordance with the Securities Act;
                  provided, however, that (i) with respect to any Holder that
                  shall become a Notice Holder after the date that is forty five
                  (45) days after the date the Initial Shelf Registration
                  becomes effective under the Securities Act, the Company shall
                  not be required to file more than one (1) such supplement
                  during any thirty (30) day period, and (ii) if a
                  post-effective amendment or a Subsequent Shelf Registration
                  Statement is required by the rules and regulations of the SEC
                  in order to permit resales by such Notice Holder, the Company
                  shall not be required to file more than one (1) post-effective

                  or Subsequent Shelf Registration Statement, as the case may
                  be, to become effective under the Securities Act as promptly
                  as practicable, but in any event by the date (the "Amendment

                        (D) if such Holder became a Notice Holder during a

                  filing, the Company shall make the required filing or filings
                  in the manner or of a type that the Company reasonably expects
                  will result in the earliest availability of a Prospectus for
                  effecting resales of Registrable Securities.

                  (ii) Notwithstanding anything contained herein to the
            contrary, the Company shall be under no obligation to name any
            Holder that is not a Notice Holder as a selling securityholder in
            any Shelf Registration Statement or related Prospectus; provided,
            however, that any Holder that becomes a Notice Holder (regardless of
            when such Holder became a Notice Holder) shall be named as a selling
            securityholder in a Shelf Registration Statement or related
            Prospectus in accordance with the requirements of this Section 2(d)
            or Section 2(a), as applicable.

            (e) The parties hereto agree that the Holders of Registrable
      Securities will suffer damages, and that it would not be feasible to
      ascertain the extent of such damages

                                       -8-

                  (i) the Initial Shelf Registration Statement has not been
            filed with the SEC on or prior to the Filing Deadline Date;

                  (ii) the Initial Shelf Registration Statement has not become
            effective under the Securities Act on or prior to the Effectiveness
            Deadline Date;

                  (iii) either a supplement to a Prospectus, a post-effective
            amendment or a Subsequent Shelf Registration Statement is required
            to be filed with the SEC and fails to be filed with the SEC within
            the prescribed period and in the manner set forth in Section 2(d)
            (the date such filing is required to be made being an "Additional
            Filing Deadline Date") or, in the case of a post-effective amendment
            or a Subsequent Shelf Registration Statement, such post-effective
            amendment or Subsequent Registration Statement does not become
            effective under the Securities Act by the Amendment Effectiveness
            Deadline Date or the Subsequent Shelf Registration Statement
            Effectiveness Deadline Date, as the case may be;

                  (iv) the Initial Shelf Registration Statement or any
            Subsequent Registration Statement is filed with the SEC and becomes
            effective under the Securities Act but shall thereafter cease to be
            effective (without being succeeded or replaced by a new Registration
            Statement that has been filed with the SEC, and has become effective
            under the Securities Act, before such cessation) or usable under the
            Securities Act for the offer and sale of Registrable Securities in
            the manner contemplated by this Agreement for a period of time
            (including any Suspension Period) which shall exceed forty five (45)
            days in the aggregate in any three (3) month period or ninety (90)
            days in the aggregate in any twelve (12) month period; or

                  (v) any Registration Statement or amendment thereto, at the
            time it becomes effective under the Securities Act, or any
            Prospectus relating thereto, at the time it is filed with the SEC
            or, if later, at the time the Registration Statement to which such
            Prospectus relates becomes effective under the Securities Act, shall
            fail to name each Holder as a selling securityholder in such a
            manner as to permit such Holder to sell its Registrable Securities
            pursuant to such Registration Statement and Prospectus in accordance
            with the Securities Act, in each case to the extent such Holder was
            entitled, pursuant to the terms of this Agreement, to be so named
            (it being understood that, without limitation, naming such Holder in
            a manner that permits such Holder to sell only a portion of such
            Holder's Registrable Securities referenced in such Holder's Notice
            and Questionnaire shall be deemed to be an "Event" (as defined
            below) for purposes of this clause (v)).

      Each of the events of a type described in any of the foregoing clauses (i)
      through (v) are individually referred to herein as an "Event," and

            (ii) above,

                  (X) the Additional Filing Deadline Date, the Amendment
            Effectiveness Deadline Date or the Subsequent Shelf Registration
            Statement Effectiveness Deadline Date, as the case may be, in the
            case of clause (iii) above,

                  (Y) the date on which the duration of the ineffectiveness or
            unusability of the Shelf Registration Statement exceeds the number
            of days permitted by clause (iv) above, in the case of clause (iv)
            above, and

                  (Z) the date the applicable Registration Statement or
            amendment thereto shall become effective under the Securities Act,
            or the date the applicable Prospectus is filed with the SEC or, if
            later, the time the Registration Statement to which such Prospectus
            relates becomes effective under the Securities Act, as the case may
            be, in the case of clause (v) above,

      are each herein referred to as an "Event Date." Events shall be deemed to
      continue until the following dates with respect to the respective types of
      Events:

                  (A) the date the Initial Shelf Registration Statement is filed
            with the SEC, in the case of an Event of the type described in
            clause (i) above;

                  (B) the date the Initial Shelf Registration Statement becomes
            effective under the Securities Act, in the case of an Event of the
            type described in clause (ii) above;

                  (C) the date a supplement to a Prospectus, a post-effective
            amendment or a Subsequent Shelf Registration Statement, whichever is
            required, is filed with the SEC (in the case of a supplement) or
            becomes effective under the Securities Act (in the case of a
            post-effective amendment or a Subsequent Shelf Registration
            Statement), in the case of an Event of the type described in clause
            (iii) above;

                  (D) the date the Initial Shelf Registration Statement or the
            Subsequent Shelf Registration Statement, as the case may be, becomes
            effective and usable again, or the date another Subsequent Shelf
            Registration Statement is filed with the SEC pursuant to Section
            2(b) and becomes effective, in the case of an Event of the type
            described in clause (iv) above; or

                  (E) the date a supplement to the Prospectus is filed with the
            SEC, or the date a post-effective amendment to the Registration
            Statement becomes effective under the Securities Act, or the date a
            Subsequent Shelf Registration Statement becomes effective under the
            Securities Act, which supplement, post-effective amendment or
            Subsequent Shelf Registration Statement, as the case may be, names
            as selling securityholders, in such a manner as to permit them to
            deliver such Prospectus supplement, or the Prospectus related to
            such post-effective

                                      -10-

            amendment or Subsequent Shelf Registration Statement, as the case
            may be, to purchasers of Registrable Securities in accordance with
            the Securities Act, all Holders entitled as herein provided to be so
            named, in the case of an Event of the type described in clause (v)
            above.

      Notwithstanding anything herein to the contrary, all Events described in
      clauses (ii), (iii) or (v) of this Section 2(e) shall be deemed to be
      suspended during any Suspension Period, except to the extent the duration
      of such Suspension Period exceeds forty five (45) days in the aggregate in
      any three (3) month period or ninety (90) days in the aggregate in any
      twelve (12) month period.

      Accordingly, commencing on (and including) any Event Date and ending on
      (but excluding) the next date on which there are no Events that have
      occurred and are continuing (an "Additional Interest Accrual Period"), the
      Company agrees to pay, as additional interest ("additional interest") and
      not as a penalty, an amount (the "Additional Interest Amount") at the rate
      described below, payable periodically on each Additional Interest Payment
      Date to Record Holders, to the extent of, for each such Additional
      Interest Payment Date, the unpaid Additional Interest Amount that has
      accrued to (but excluding) such Additional Interest Payment Date (or, if
      the Additional Interest Accrual Period shall have ended prior to such
      Additional Interest Payment Date, to (but excluding) the day immediately
      after the last day of such Additional Interest Accrual Period); provided,
      however, that any unpaid Additional Interest Amount that has accrued with
      respect to any Note, or portion thereof, called for Redemption on a
      Redemption Date, or purchased by the Company pursuant to a Repurchase at
      Holder's Option or Repurchase Upon Repurchase Event on an Option Purchase
      Date or Repurchase Date, as the case may be, that is after the close of
      business on the Record Date relating to such Additional Interest Payment
      Date and before such Additional Interest Payment Date, shall, in each
      case, be instead paid, on such Redemption Date, Option Purchase Date or
      Repurchase Date, as the case may be, to the Holder who submitted such Note
      or portion thereof for Redemption, Repurchase at Holder's Option or
      Repurchase Upon Repurchase Event, as the case may be.

      The Additional Interest Amount shall accrue at a rate per annum equal to
      one quarter of one percent (0.25%) for the ninety (90) day period
      beginning on, and including, the Event Date and thereafter at a rate per
      annum equal to one half of one percent (0.50%) of the aggregate principal
      amount of the Notes of which such Record Holders were holders of record at
      the close of business on the applicable Record Date; provided, however,
      that, notwithstanding the foregoing:

                  (I) except to the extent provided in the final paragraph of
            this Section 2(e), no Additional Interest Amounts shall accrue as to
            any Covered Security from and after the earlier of (x) the date such
            Covered Security is no longer a Registrable Security, (y) in the
            case such Covered Security is a Note, the date, and to the extent,
            such Note is converted into shares of Common Stock in accordance
            with the Indenture and (z) the expiration of the Effectiveness
            Period;

                                      -11-

<PAGE>

                  (II) only those Holders (or their subsequent transferees)
            failing to be named as selling securityholders in the manner
            prescribed in Section 2(e)(v) above shall be entitled to receive any
            Additional Interest Amounts that have accrued solely with respect to
            an Event of the type described in Section 2(e)(v) above (it being
            understood that this clause (II) shall not impair any right of any
            Holder to receive Additional Interest Amounts that have accrued with
            respect to an Event other than an Event of the type described in
            Section 2(e)(v) above);

                  (III) only those Holders (or their subsequent transferees)
            whose delivery of a Notice and Questionnaire gave rise to the
            obligation of the Company, pursuant to Section 2(d)(i), to file and,
            if applicable, make effective under the Securities Act the
            supplement, post-effective amendment or Subsequent Shelf
            Registration Statement referred to in Section 2(e)(iii) above shall
            be entitled to receive any Additional Interest Amounts that have
            accrued solely with respect to an Event of the type described in
            Section 2(e)(iii) above (it being understood that this clause (III)
            shall not impair any right of any Holder to receive Additional
            Interest Amounts that have accrued with respect to an Event other
            than an Event of the type described in Section 2(e)(iii) above); and

                  (IV) if a Covered Security ceases to be outstanding during an
            Additional Interest Accrual Period for which an Additional Interest
            Amount would be payable with respect to such Covered Security, then
            the Additional Interest Amount payable hereunder with respect to
            such Covered Security shall be prorated on the basis of the number
            of full days such Covered Security is outstanding during such
            Additional Interest Accrual Period.

      The rate of accrual of the Additional Interest Amount with respect to any
      period shall not exceed the rate provided for in this Section 2(e)
      notwithstanding the occurrence of multiple concurrent Events. Following
      the cure of all Events requiring the payment by the Company of Additional
      Interest Amounts with respect to Registrable Securities pursuant to this
      Section, the accrual of Additional Interest Amounts shall cease (without
      in any way limiting the effect of any subsequent Event requiring the
      payment of Additional Interest Amounts by the Company). All installments
      of Additional Interest shall be paid by wire transfer of immediately
      available funds to the account specified by the Notice Holder or, if no
      such account is specified, by mailing a check to such Notice Holder's
      address shown in the register of the registrar for the Notes or for the
      Underlying Common Stock, as the case may be.

      All of the Company's obligations set forth in this Section 2(e) that are
      outstanding with respect to any Registrable Security at the time such
      Registrable Security ceases to be a Registrable Security shall survive
      until such time as all such obligations with respect to such security have
      been satisfied in full (notwithstanding termination of this Agreement
      pursuant to Section 9(n)).

      The parties hereto agree that the additional interest provided for in this
      Section 2(e) constitutes a reasonable estimate of the damages in respect
      of the Notes that may be

                                      -12-

<PAGE>

      incurred by Holders of the Notes by reason of an Event relating to such
      Notes, including, without limitation, the failure of a Shelf Registration
      Statement to be filed, become effective under the Securities Act, amended
      or replaced to include the names of all Notice Holders or available for
      effecting resales of Registrable Securities in accordance with the
      provisions hereof. Subject to any rights that may arise pursuant to
      Section 6 hereof, the parties hereto also agree that the Company shall
      have no liability to a Holder of Notes for monetary damages with respect
      to an Event relating to such Notes other than the additional interest
      provided for in this Section 2(e); provided, however, that nothing in this
      paragraph shall impair any rights a holder of Underlying Common Stock, to
      the extent such holder holds Underlying Common Stock and not Notes, may
      have with respect to an Event relating to such Underlying Common Stock (it
      being understood that interest that accrues, in accordance with the
      immediately following paragraph, on an Additional Interest Amount with
      respect to an Event that relates to a Note shall be deemed, for purposes
      of this proviso, to be an Event that relates to such Note notwithstanding
      any subsequent conversion of such Note into shares of Underlying Common
      Stock).

      If any Additional Interest Amounts are not paid when due, then, to the
      extent permitted by law, such overdue Additional Interest Amounts, if any,
      shall bear interest, compounded semi-annually, until paid at the rate of
      interest payable with respect to overdue amounts on the Notes pursuant to
      Section 2.12 of the Indenture.

            (f) The Trustee shall be entitled, on behalf of Holders, to seek any
      available remedy for the enforcement of this Agreement, including for the
      payment of any Additional Interest Amount.

      3. Registration Procedures. In connection with the registration
obligations of the Company under Section 2 hereof, the Company shall:

            (a) Prepare and file with the SEC a Shelf Registration Statement or
      Shelf Registration Statements on Form S-1 or Form S-3 or any other
      appropriate form under the Securities Act available for the sale of the
      Registrable Securities by the Holders thereof in accordance with the
      method or methods of distribution described in the Notice and
      Questionnaires, and use its reasonable best efforts to cause each such
      Shelf Registration Statement to become effective under the Securities Act
      and remain effective under the Securities Act as provided herein;
      provided, that, before filing any Shelf Registration Statement or
      Prospectus or any amendments or supplements thereto with the SEC, the
      Company shall furnish to the Initial Purchasers and counsel for the
      Initial Purchasers and, if applicable, Designated Counsel copies of all
      such documents proposed to be filed and shall give reasonable
      consideration to such comments as the Initial Purchasers, counsel for the
      Initial Purchasers or Designated Counsel reasonably shall propose within
      two (2) Business Days of the delivery of such copies to the Initial
      Purchasers and such counsel.

            (b) Prepare and file with the SEC such amendments and post-effective
      amendments to each Shelf Registration Statement as may be necessary,
      except to the

                                      -13-

<PAGE>

      extent permitted under Section 3(i) hereof, to keep such Shelf
      Registration Statement or Subsequent Shelf Registration Statement
      continuously effective until the expiration of the Effectiveness Period;
      cause the related Prospectus to be supplemented by any required Prospectus
      supplement and, as so supplemented, to be filed with the SEC pursuant to
      Rule 424 (or any similar provisions then in force) under the Securities
      Act; and, except to the extent permitted under Section 3(i) hereof, comply
      with the provisions of the Securities Act applicable to it with respect to
      the disposition of all securities covered by each Shelf Registration
      Statement during the Effectiveness Period in accordance with the intended
      methods of disposition by the sellers thereof set forth in such Shelf
      Registration Statement as so amended or such Prospectus as so
      supplemented.

            (c) As promptly as practicable, give notice to the Notice Holders,
      the Initial Purchasers, counsel for the Initial Purchasers and, if
      applicable, Designated Counsel:

                  (i) when any Prospectus, Prospectus supplement, Shelf
            Registration Statement or post-effective amendment to a Shelf
            Registration Statement has been filed with the SEC and, with respect
            to a Shelf Registration Statement or any post-effective amendment,
            when the same has become effective under the Securities Act,

                  (ii) of any request, following the effectiveness of a Shelf
            Registration Statement under the Securities Act, by the SEC or any
            other federal or state governmental authority for amendments or
            supplements to such Shelf Registration Statement or the related
            Prospectus or for additional information,

                  (iii) of the issuance by the SEC or any other federal or state
            governmental authority of any stop order suspending the
            effectiveness of any Shelf Registration Statement or the initiation
            or threatening of any proceedings for that purpose,

                  (iv) of the receipt by the Company or its legal counsel of any
            notification with respect to the suspension of the qualification or
            exemption from qualification of any of the Registrable Securities
            for sale in any jurisdiction or the initiation or threatening of any
            proceeding for such purpose,

                  (v) after the effective date of any Shelf Registration
            Statement filed with the SEC pursuant to this Agreement, of the
            occurrence of (but not the nature of or details concerning) a
            Material Event, and

                  (vi) of the determination by the Company that a post-effective
            amendment to a Shelf Registration Statement or a Subsequent Shelf
            Registration Statement will be filed with the SEC, which notice may,
            at the discretion of the Company (or as required pursuant to Section
            3(i)), state that it constitutes a Suspension Notice, in which event
            the provisions of Section 3(i) shall apply.

            (d) Subject to the terms hereof, use its reasonable best efforts to
      (i) prevent the

                                      -14-

<PAGE>

      issuance of, and, if issued, to obtain the withdrawal of, any order
      suspending the effectiveness of a Shelf Registration Statement and (ii)
      obtain the lifting of any suspension of the qualification (or exemption
      from qualification) of any of the Registrable Securities for sale in any
      jurisdiction in which they have been qualified for sale, in either case at
      the earliest possible moment, and provide prompt notice to each Notice
      Holder and the Initial Purchasers, counsel for the Initial Purchasers and,
      if applicable, Designated Counsel, of the withdrawal or lifting of any
      such order or suspension.

            (e) If requested by the Initial Purchasers or any Notice Holder, as
      promptly as practicable incorporate in a Prospectus supplement or a
      post-effective amendment to a Shelf Registration Statement such
      information as the Initial Purchasers, such Notice Holder or counsel for
      the Initial Purchasers or, if applicable, Designated Counsel shall
      determine to be required to be included therein by the Securities Act and
      make any required filings of such Prospectus supplement or such
      post-effective amendment; provided, however, that the Company shall not be
      required to take any action under this Section 3(e) unless the Company
      receives the opinion of counsel for the party making such request that
      such action is required by the Securities Act.

            (f) As promptly as practicable, furnish, upon request, to each
      Notice Holder and the Initial Purchasers, without charge, at least one (1)
      conformed copy of each Shelf Registration Statement and each amendment
      thereto, including financial statements but excluding schedules, all
      documents incorporated or deemed to be incorporated therein by reference
      and all exhibits (unless requested in writing to the Company by such
      Notice Holder or the Initial Purchasers).

            (g) During the Effectiveness Period, deliver to each Notice Holder,
      in connection with any sale of Registrable Securities pursuant to a Shelf
      Registration Statement, without charge, as many copies of the Prospectus
      or Prospectuses relating to such Registrable Securities and any amendment
      or supplement thereto as such Notice Holder may reasonably request; and
      the Company hereby consents (except during such periods that a Suspension
      Notice is outstanding and has not been revoked) to the use of such
      Prospectus and each amendment or supplement thereto by each Notice Holder,
      in connection with any offering and sale of the Registrable Securities
      covered by such Prospectus or any amendment or supplement thereto in the
      manner set forth therein.

            (h) Prior to any public offering of the Registrable Securities
      pursuant to a Shelf Registration Statement, use its reasonable best
      efforts to register or qualify or cooperate with the Notice Holders in
      connection with the registration or qualification (or exemption from such
      registration or qualification) of such Registrable Securities for offer
      and sale under the securities or Blue Sky laws of such jurisdictions
      within the United States as any Notice Holder reasonably requests in
      writing (which request may be included in the Notice and Questionnaire);
      use its reasonable best efforts to keep each such registration or
      qualification (or exemption therefrom) effective during the Effectiveness
      Period in connection with such Notice Holder's offer and sale of
      Registrable Securities pursuant to such registration or qualification (or
      exemption

                                      -15-

      therefrom) and do any and all other acts or things reasonably necessary or
      advisable to enable the disposition in such jurisdictions of such
      Registrable Securities in the manner set forth in the relevant Shelf
      Registration Statement and the related Prospectus; provided, however, that
      the Company will not be required to (i) qualify generally to do business
      in any jurisdiction where it is not then so qualified, (ii) take any
      action that would subject it to general service of process in suits, other
      than those arising out of the offering or sale of Registrable Securities
      or arising in connection with this Agreement, in any jurisdiction where it
      is not now so subject, or (iii) take any action that would subject it to
      taxation in any jurisdiction where it is not then so subject.

            (i) Upon: (A) the issuance by the SEC of a stop order suspending the
      effectiveness of any Shelf Registration Statement or the initiation of
      proceedings with respect to any Shelf Registration Statement under Section
      8(d) or 8(e) of the Securities Act; (B) the occurrence of any event or the
      existence of any fact as a result of which any Shelf Registration
      Statement shall contain any untrue statement of a material fact or omit to
      state any material fact required to be stated therein or necessary to make
      the statements therein not misleading, or any Prospectus shall contain any
      untrue statement of a material fact or omit to state any material fact
      necessary in order to make the statements therein, in the light of the
      circumstances under which they were made, not misleading; or (C) the
      occurrence or existence of any pending corporate development (a "Material
      Event") that, in the reasonable discretion of the Company, makes it
      appropriate to suspend the availability of any Shelf Registration
      Statement and the related Prospectus,

                  (i) in the case of clause (B) or (C) above, subject to the
            next sentence, as promptly as practicable, prepare and file, if
            necessary pursuant to the Securities Act, a post-effective amendment
            to such Shelf Registration Statement or a supplement to such
            Prospectus or any document incorporated therein by reference or file
            any other required document that would be incorporated by reference
            into such Shelf Registration Statement and Prospectus so that such
            Shelf Registration Statement does not contain any untrue statement
            of a material fact or omit to state any material fact required to be
            stated therein or necessary to make the statements therein not
            misleading, and so that such Prospectus does not contain any untrue
            statement of a material fact or omit to state any material fact
            necessary in order to make the statements therein, in the light of
            the circumstances under which they were made, not misleading, as
            thereafter delivered to the purchasers of the Registrable Securities
            being sold thereunder (it being understood that the Company may rely
            on information provided by each Notice Holder with respect to such
            Notice Holder), and, in the case of a post-effective amendment to a
            Shelf Registration Statement, subject to the next sentence, use its
            reasonable best efforts to cause it to become effective under the
            Securities Act as promptly as practicable, and

                  (ii) give notice to the Notice Holders, the Initial
            Purchasers, counsel for the Initial Purchasers and, if applicable,
            Designated Counsel that the availability of the Shelf Registration
            Statement is suspended (a "Suspension Notice") (and, upon receipt of
            any Suspension Notice, each Notice Holder agrees

                                      -16-
<PAGE>

            not to sell any Registrable Securities pursuant to such Shelf
            Registration Statement until such Notice Holder's receipt of copies
            of the supplemented or amended Prospectus provided for in clause (i)
            above or until such Notice Holder is advised in writing by the
            Company that the Prospectus may be used).

      The Company will use its reasonable best efforts to ensure that the use of
      the Prospectus may be resumed (x) in the case of clause (A) above, as
      promptly as is practicable, (y) in the case of clause (B) above, as soon
      as, in the reasonable judgment of the Company, the Shelf Registration
      Statement does not contain any untrue statement of a material fact or omit
      to state any material fact required to be stated therein or necessary to
      make the statements therein not misleading and the Prospectus does not
      contain any untrue statement of a material fact or omit to state any
      material fact necessary in order to make the statements therein, in the
      light of the circumstances under which they were made, not misleading, and
      (z) in the case of clause (C) above, as soon as, in the reasonable
      discretion of the Company, such suspension is no longer appropriate. The
      period during which the availability of the Shelf Registration Statement
      and any Prospectus may be suspended (the "Suspension Period") without the
      Company incurring any obligation to pay additional interest pursuant to
      Section 2(e) shall not exceed forty five (45) days in the aggregate in any
      three (3) month period or ninety (90) days in the aggregate in any twelve
      (12) month period. The Effectiveness Period shall be extended by the
      number of days from and including the date of the giving of the Suspension
      Notice to and including the date on which the Notice Holder received
      copies of the supplemented or amended Prospectus provided in clause (i)
      above, or the date on which it is advised in writing by the Company that
      the Prospectus may be used and has received copies of any additional or
      supplemental filings that are incorporated or deemed incorporated by
      reference in such Prospectus.

            (j) Make available for inspection during normal business hours by
      representatives for the Notice Holders and any underwriters participating
      in any disposition pursuant to any Shelf Registration Statement and any
      broker-dealers, attorneys and accountants retained by such Notice Holders
      or any such underwriters, all relevant financial and other records and
      pertinent corporate documents and properties of the Company and its
      subsidiaries, and cause the appropriate officers, directors and employees
      of the Company and its subsidiaries to make available for inspection
      during normal business hours all relevant information reasonably requested
      by such representatives for the Notice Holders, or any such underwriters,
      broker-dealers, attorneys or accountants in connection with such
      disposition, in each case as is customary for similar "due diligence"
      examinations; provided, however, that such persons shall first agree in
      writing with the Company that any information that is confidential at the
      time of delivery of such information shall be kept confidential by such
      persons and shall be used solely for the purposes of exercising rights
      under this Agreement, unless (i) disclosure of such information is
      required by court or administrative order or is necessary to respond to
      inquiries of governmental or regulatory authorities, (ii) disclosure of
      such information is required by law (including any disclosure requirements
      pursuant to federal securities laws in connection with the filing of any
      Shelf Registration Statement or the use of any Prospectus referred to in
      this Agreement) or necessary to defend or prosecute a claim

                                      -17-
<PAGE>

      brought against or by any such persons (e.g., to establish a "due
      diligence" defense), (iii) such information becomes generally available to
      the public other than as a result of a disclosure or failure to safeguard
      by any such person or (iv) such information becomes available to any such
      person from a source other than the Company and such source is not bound
      by a confidentiality agreement or is not otherwise under a duty of trust
      to the Company; provided further, that the foregoing inspection and
      information gathering shall, to the greatest extent possible, be
      coordinated on behalf of all the Notice Holders and the other parties
      entitled thereto by one counsel for such Notice Holders and such other
      parties.

            (k) Comply with all applicable rules and regulations of the SEC that
      are applicable to any Shelf Registration Statement; and make generally
      available to its securityholders earnings statements (which need not be
      audited) satisfying the provisions of Section 11(a) of the Securities Act
      and Rule 158 thereunder (or any similar rule promulgated under the
      Securities Act), which statements shall cover a period of twelve (12)
      months commencing on the first day of the first fiscal quarter of the
      Company commencing after the effective date of each Shelf Registration
      Statement (within the meaning of Rule 158(c) under the Securities Act),
      and which statements shall be so made generally available to the Company's
      securityholders no later than forty (40) days after the end of the
      applicable twelve (12) month period if such period ends on or after
      December 15, 2004 and before December 15, 2006 (or thirty five (35) days
      after the end of the applicable twelve (12) month period if such period
      ends on or after December 15, 2006) (or, if such earnings statement is
      filed with the SEC on Form 10-K under the Exchange Act, (i) seventy five
      (75) days after the end of the applicable twelve (12) month period if such
      period ends before December 15, 2005 or (ii) sixty (60) days after the end
      of the applicable twelve (12) month period if such period ends on or after
      December 15, 2005); provided, however, that, notwithstanding the foregoing
      in this Section 3(k), to the extent any such earnings statement will be
      contained in one report, or any combination of reports, on Form 10-K
      and/or Form 10-Q under the Exchange Act filed by the Company with the SEC
      and the deadline, under the Exchange Act, for the Company to file, with
      the SEC, such report, if such earnings statement is contained in a Form
      10-K, or to file, with the SEC, the last of such reports which together
      constitute such earnings statement, if such earnings statement is
      contained in a combination of reports, is a date that is later than the
      applicable foregoing deadline, then such later date shall apply in place
      of the otherwise applicable foregoing deadline.

            (l) Cooperate with each Notice Holder to facilitate the timely
      preparation and delivery of certificates representing Registrable
      Securities sold pursuant to a Shelf Registration Statement, which
      certificates shall not bear any restrictive legends, and cause such
      Registrable Securities to be in such denominations as are permitted by the
      Indenture and registered in such names as such Notice Holder may request
      in writing at least two (2) Business Days prior to any sale of such
      Registrable Securities.

            (m) Provide a CUSIP number for all Registrable Securities covered by
      a Shelf Registration Statement not later than the effective date of the
      Initial Shelf Registration Statement and provide the Trustee and the
      transfer agent for the Common Stock with

                                      -18-

<PAGE>

      certificates for the Registrable Securities that are in a form eligible
      for deposit with The Depository Trust Company.

            (n) Cooperate and assist in any filings required to be made with the
      National Association of Securities Dealers, Inc.

            (o) Upon the filing of the Initial Shelf Registration Statement, and
      upon the effectiveness under the Securities Act of the Initial Shelf
      Registration Statement, announce the same, in each case by release through
      a reputable national newswire service.

            (p) Cause the Indenture to be qualified under the TIA not later than
      the effective date of the Initial Shelf Registration Statement; and, in
      connection therewith, cooperate with the Trustee to effect such changes to
      the Indenture as may be required for the Indenture to be so qualified in
      accordance with the terms of the TIA and execute, and use its reasonable
      best efforts to cause the Trustee to execute, all documents as may be
      required to effect such changes, and all other forms and documents
      required to be filed with the SEC to enable the Indenture to be so
      qualified in a timely manner.

            (q) Use its reasonable best efforts to cause the Underlying Common
      Stock to be listed on The Nasdaq National Market.

      4. Holder's Obligations. Each Holder agrees, by acquisition of the
Registrable Securities, that no Holder of Registrable Securities shall be
entitled to sell any of such Registrable Securities pursuant to a Shelf
Registration Statement or to receive a Prospectus relating thereto, unless such
Holder has furnished the Company with a Notice and Questionnaire as required
pursuant to Section 2(d) hereof (including the information required to be
included in such Notice and Questionnaire) and the information set forth in the
next sentence. Each Notice Holder agrees promptly to furnish to the Company all
information required to be disclosed in order to make the information previously
furnished to the Company by such Notice Holder not misleading and any other
information regarding such Notice Holder and the distribution of such
Registrable Securities as the Company may from time to time reasonably request.
Any sale of any Registrable Securities by any Holder shall constitute a
representation and warranty by such Holder that the information relating to such
Holder and its plan of distribution is as set forth in the Prospectus delivered
by such Holder in connection with such disposition, that such Prospectus does
not as of the time of such sale contain any untrue statement of a material fact
relating to or provided by such Holder or its plan of distribution and that such
Prospectus does not as of the time of such sale omit to state any material fact
relating to or provided by such Holder or its plan of distribution necessary in
order to make the statements in such Prospectus, in the light of the
circumstances under which they were made, not misleading. Each Holder agrees to
keep confidential the receipt by it of any Suspension Notice and the contents
thereof, except as required pursuant to applicable law.

      5. Registration Expenses. The Company shall bear all fees and expenses
incurred in connection with the performance by the Company of its obligations
under Section 2 and Section 3 of this Agreement whether or not any of the Shelf
Registration Statements are filed or declared

                                      -19-

<PAGE>

effective under the Securities Act. Such fees and expenses ("Registration
Expenses") shall include, without limitation, (i) all registration and filing
fees and expenses (including, without limitation, fees and expenses (x) with
respect to filings required to be made with the National Association of
Securities Dealers, Inc. and (y) of compliance with federal securities laws and
state securities or Blue Sky laws (including, without limitation, reasonable
fees and disbursements of counsel for the Holders in connection with Blue Sky
qualifications of the Registrable Securities under the laws of such
jurisdictions as the Notice Holders of a majority of the Registrable Securities
being sold pursuant to a Shelf Registration Statement may designate), (ii) all
printing expenses (including, without limitation, expenses of printing
certificates for Registrable Securities in a form eligible for deposit with The
Depository Trust Company and printing Prospectuses), (iii) all duplication and
mailing expenses relating to copies of any Shelf Registration Statement or
Prospectus delivered to any Holders hereunder, (iv) all fees and disbursements
of counsel for the Company, (v) the fees and disbursements of one counsel
("Designated Counsel") for the Holders in connection with the Shelf Registration
Statement, which Designated Counsel shall be designated in writing to the
Company by Holders of a majority of the Registrable Securities (provided,
however, that in no event shall the Company be obligated pursuant to this clause
(v) to pay an amount to the extent such amount, in the aggregate with all other
payments theretofore made pursuant to this clause (v), exceeds fifteen thousand
dollars ($15,000)), (vi) all fees and disbursements of the Trustee and its
counsel and of the registrar and transfer agent for the Common Stock, and (vii)
Securities Act liability insurance obtained by the Company in its sole
discretion. In addition, the Company shall pay the internal expenses of the
Company (including, without limitation, all salaries and expenses of officers
and employees performing legal or accounting duties), the expense of any annual
audit or quarterly review, the fees and expenses incurred in connection with the
listing by the Company of the Registrable Securities on any securities exchange
or quotation system on which similar securities of the Company are then listed
and the fees and expenses of any person, including, without limitation, special
experts, retained by the Company. Except as provided above, each Holder shall
pay all brokerage fees and commissions, all transfer taxes, the fees and
expenses of any advisors the Holder engages and all similar fees and costs
relating to such Holder's disposition of Registrable Securities.

      6. Indemnification, Contribution.

            (a) The Company agrees to indemnify, defend and hold harmless each
      Initial Purchaser, each Holder, each person (a "Controlling Person"), if
      any, who controls any Initial Purchaser or Holder within the meaning of
      Section 15 of the Securities Act or Section 20 of the Exchange Act and the
      respective officers, directors, partners, employees, representatives and
      agents of any Initial Purchaser, the Holders or any Controlling Person
      (each, an "Indemnified Party"), from and against any loss, damage,
      expense, liability, claim or any actions in respect thereof (including the
      reasonable cost of investigation) which such Indemnified Party may incur
      or become subject to under the Securities Act, the Exchange Act or
      otherwise, insofar as such loss, damage, expense, liability, claim or
      action arises out of or is based upon any untrue statement or alleged
      untrue statement of a material fact contained in any Shelf Registration
      Statement or Prospectus, including any document incorporated by reference
      therein, or in any amendment or supplement thereto or in any preliminary
      prospectus, or arises out of or is

                                      -20-
<PAGE>

      based upon any omission or alleged omission to state a material fact
      required to be stated in any Shelf Registration Statement or in any
      amendment or supplement thereto or necessary to make the statements
      therein not misleading, or arises out of or is based upon any omission or
      alleged omission to state a material fact necessary in order to make the
      statements made in any Prospectus or in any amendment or supplement
      thereto or in any preliminary prospectus, in the light of the
      circumstances under which such statements were made, not misleading, and
      the Company shall reimburse, as incurred, the Indemnified Parties for any
      legal or other expenses reasonably incurred by them in connection with
      investigating or defending any such loss, damage, expense, liability,
      claim or action in respect thereof; provided, however, that the Company
      shall not be required to provide any indemnification pursuant to this
      Section 6(a) in any such case insofar as any such loss, damage, expense,
      liability, claim or action arises out of or is based upon any untrue
      statement or omission or alleged untrue statement or omission of a
      material fact contained in, or omitted from, and in conformity with
      information furnished in writing by or on behalf of an Initial Purchaser
      or a Holder to the Company expressly for use in, any Shelf Registration
      Statement or any Prospectus, including information provided by such Holder
      in a Notice and Questionnaire; provided further, however, that this
      indemnity agreement will (A) be in addition to any liability which the
      Company may otherwise have to such Indemnified Party and (B) not apply to
      any loss, damage, expense, liability or claim arising from an offer or
      sale, occurring during a Suspension Period, of Registrable Securities by a
      Holder to whom the Company theretofore provided a Suspension Notice in
      accordance with Section 3(i).

            (b) Each Holder, severally and not jointly, agrees to indemnify,
      defend and hold harmless the Company, its directors, officers, employees
      and any person who controls the Company within the meaning of Section 15
      of the Securities Act or Section 20 of the Exchange Act (each, a "Company
      Indemnified Party") from and against any loss, damage, expense, liability,
      claim or any actions in respect thereof (including the reasonable cost of
      investigation) which such Company Indemnified Party may incur or become
      subject to under the Securities Act, the Exchange Act or otherwise,
      insofar as such loss, damage, expense, liability, claim or action arises
      out of or is based upon (A) any untrue statement or alleged untrue
      statement of a material fact contained in, and in conformity with
      information (the "Holder Information") furnished in writing by or on
      behalf of such Holder to the Company expressly for use in, any Shelf
      Registration Statement or Prospectus, or in any amendment or supplement
      thereto, or arises out of or is based upon any omission or alleged
      omission to state a material fact in connection with such Holder
      Information required to be stated in any Shelf Registration Statement or
      Prospectus, or any amendment or supplement thereto, or necessary to make
      such Holder Information not misleading, (B) a sale, by such Holder
      pursuant to a Shelf Registration Statement in or with respect to which
      such Holder is named as a selling security holder, of Registrable
      Securities during a Suspension Period, provided that the Company shall
      have theretofore provided such Holder a Suspension Notice in accordance
      with Section 3(i), or (C) a public sale of Registrable Securities by such
      Holder without delivery, if required by the Securities Act, of the most
      recent applicable Prospectus provided to such Holder by the Company
      pursuant to Section 3(g) or Section 2(d)(i)(C); and, subject to the
      limitation set forth in the immediately preceding clause, each Holder
      shall reimburse, as

                                      -21-

<PAGE>

      incurred, the Company for any legal or other expenses reasonably incurred
      by the Company or any such controlling person in connection with
      investigating or defending any loss, damage, expense, liability, claim or
      action in respect thereof. This indemnity agreement will be in addition to
      any liability which such Holder may otherwise have to the Company or any
      of its controlling persons. In no event shall the liability of any selling
      Holder of Registrable Securities hereunder be greater in amount than the
      dollar amount of the proceeds received by such Holder upon the sale,
      pursuant to the Shelf Registration Statement, of the Registrable
      Securities giving rise to such indemnification obligation.

            (c) If any action, suit or proceeding (each, a "Proceeding") is
      brought against any person in respect of which indemnity may be sought
      pursuant to either Section 6(a) or Section 6(b), such person (the
      "Indemnified Party") shall promptly notify the person against whom such
      indemnity may be sought (the "Indemnifying Party") in writing of the
      institution of such Proceeding and the Indemnifying Party shall assume the
      defense of such Proceeding; provided, however, that the failure to so
      notify such Indemnifying Party shall not relieve such Indemnifying Party
      from any liability which it may have to such Indemnified Party or
      otherwise, except to the extent such failure to notify materially
      prejudices such Indemnifying Party. Such Indemnified Party shall have the
      right to employ its own counsel in any such case, but the fees and
      expenses of such counsel shall be at the expense of such Indemnified Party
      unless the employment of such counsel shall have been authorized in
      writing by such Indemnifying Party in connection with the defense of such
      Proceeding or such Indemnifying Party shall not have employed counsel to
      have charge of the defense of such Proceeding within thirty (30) days of
      the receipt of notice thereof or such Indemnified Party shall have
      reasonably concluded upon the written advice of counsel that there may be
      one or more defenses available to it that are different from, additional
      to or in conflict with those available to such Indemnifying Party (in
      which case such Indemnifying Party shall not have the right to direct that
      portion of the defense of such Proceeding on behalf of the Indemnified
      Party, but such Indemnifying Party may employ counsel and participate in
      the defense thereof but the fees and expenses of such counsel shall be at
      the expense of such Indemnifying Party), in any of which events such
      reasonable fees and expenses shall be borne by such Indemnifying Party and
      paid as incurred (it being understood, however, that such Indemnifying
      Party shall not be liable for the expenses of more than one separate
      counsel in any one Proceeding or series of related Proceedings together
      with reasonably necessary local counsel representing the Indemnified
      Parties who are parties to such action). An Indemnifying Party shall not
      be liable for any settlement of such Proceeding effected without the
      written consent of such Indemnifying Party, but if settled with the
      written consent of such Indemnifying Party, such Indemnifying Party agrees
      to indemnify and hold harmless an Indemnified Party from and against any
      loss or liability by reason of such settlement. Notwithstanding the
      foregoing sentence, if at any time an Indemnified Party shall have
      requested an Indemnifying Party to reimburse such Indemnified Party for
      fees and expenses of counsel as contemplated by the second sentence of
      this paragraph, then such Indemnifying Party agrees that it shall be
      liable for any settlement of any Proceeding effected without its written
      consent if (i) such settlement is entered into more than sixty (60)
      Business Days after receipt by such Indemnifying Party of the aforesaid

                                      -22-

      request, (ii) such Indemnifying Party shall not have fully reimbursed such
      Indemnified Party in accordance with such request prior to the date of
      such settlement and (iii) such Indemnified Party shall have given such
      Indemnifying Party at least thirty (30) days' prior notice of its
      intention to settle. No Indemnifying Party shall, without the prior
      written consent of any Indemnified Party, effect any settlement of any
      pending or threatened Proceeding in respect of which such Indemnified
      Party is or could have been a party and indemnity could have been sought
      hereunder by such Indemnified Party, unless such settlement includes an
      unconditional release of such Indemnified Party from all liability on
      claims that are the subject matter of such Proceeding and does not include
      an admission of fault or culpability or a failure to act by or on behalf
      of such Indemnified Party.

            (d) If the indemnification provided for in this Section 6 is
      unavailable to an Indemnified Party under Section 6(a) or Section 6(b), or
      insufficient to hold such Indemnified Party harmless, in respect of any
      losses, damages, expenses, liabilities, claims or actions referred to
      therein, then each applicable Indemnifying Party, in lieu of indemnifying
      such Indemnified Party, shall contribute to the amount paid or payable by
      such Indemnified Party as a result of such losses, damages, expenses,
      liabilities, claims or actions (i) in such proportion as is appropriate to
      reflect the relative benefits received by the Company, on the one hand,
      and by the Holders or the Initial Purchasers, on the other hand, from the
      offering of the Registrable Securities or (ii) if the allocation provided
      by clause (i) above is not permitted by applicable law, in such proportion
      as is appropriate to reflect not only the relative benefits referred to in
      clause (i) above but also the relative fault of the Company, on the one
      hand, and of the Holders or the Initial Purchasers, on the other hand, in
      connection with the statements or omissions which resulted in such losses,
      damages, expenses, liabilities, claims or actions, as well as any other
      relevant equitable considerations. The relative fault of the Company, on
      the one hand, and of the Holders or the Initial Purchasers, on the other
      hand, shall be determined by reference to, among other things, whether the
      untrue statement or alleged untrue statement of a material fact or
      omission or alleged omission relates to information supplied by the
      Company or by the Holders or the Initial Purchasers and the parties'
      relative intent, knowledge, access to information and opportunity to
      correct or prevent such statement or omission. The amount paid or payable
      by a party as a result of the losses, damages, expenses, liabilities,
      claims and actions referred to above shall be deemed to include any
      reasonable legal or other fees or expenses reasonably incurred by such
      party in connection with investigating or defending any Proceeding.

            (e) The Company, the Holders and each Initial Purchaser agree that
      it would not be just and equitable if contribution pursuant to this
      Section 6 were determined by pro rata allocation or by any other method of
      allocation which does not take account of the equitable considerations
      referred to in Section 6(d) above. Notwithstanding the provisions of this
      Section 6, no Holder shall be required to contribute any amount in excess
      of the amount by which the total price at which the Registrable Securities
      giving rise to such contribution obligation and sold by such Holder were
      offered to the public exceeds the amount of any damages which it has
      otherwise been required to pay by reason of such untrue or alleged untrue
      statement or omission or alleged omission. No

                                      -23-

      person guilty of fraudulent misrepresentation (within the meaning of
      Section 11(f) of the Securities Act) shall be entitled to contribution
      from any person who was not guilty of such fraudulent misrepresentation.
      The Holders' respective obligations to contribute pursuant to this Section
      6 are several in proportion to the respective amount of Registrable
      Securities they have sold pursuant to a Shelf Registration Statement, and
      not joint. The remedies provided for in this Section 6 are not exclusive
      and shall not limit any rights or remedies which may otherwise be
      available to any indemnified party at law or in equity.

            (f) The indemnity and contribution provisions contained in this
      Section 6 shall remain operative and in full force and effect regardless
      of (i) any termination of this Agreement, (ii) any investigation made by
      or on behalf of any Holder or any Initial Purchaser or any person
      controlling any Holder or Initial Purchaser, or the Company, or the
      Company's officers or directors or any person controlling the Company and
      (iii) the sale of any Registrable Security by any Holder.

      7. Information Requirements.

            (a) The Company covenants that, if at any time before the end of the
      Effectiveness Period it is not subject to the reporting requirements of
      the Exchange Act, it will cooperate with any Holder of Registrable
      Securities and take such further action as any Holder of Registrable
      Securities may reasonably request in writing (including, without
      limitation, making such representations as any such Holder may reasonably
      request), all to the extent required from time to time to enable such
      Holder to sell Registrable Securities without registration under the
      Securities Act within the limitations of the exemptions provided by Rule
      144, Rule 144A and Regulation S under the Securities Act and customarily
      taken in connection with sales pursuant to such exemptions. Upon the
      written request of any Holder, the Company shall deliver to such Holder a
      written statement as to whether the Company has complied with the
      reporting requirements of the Exchange Act during the preceding twelve
      (12) months, unless such a statement has been included in the Company's
      most recent quarterly or annual report filed with the SEC pursuant to
      Section 13 or Section 15(d) of Exchange Act.

            (b) During the Effectiveness Period, the Company shall use its
      commercially reasonable efforts to (i) file the reports required to be
      filed by it under the Exchange Act during the Effectiveness Period and
      (ii) comply with the registrant requirements set forth in the instructions
      to Form S-3.

      8. Underwritten Registrations. Notwithstanding anything herein to the
contrary, no Registrable Securities covered by a Shelf Registration Statement
may be sold in an underwritten offering pursuant to the Shelf Registration
Statement without the prior written consent of the Company. No person may
participate in any underwritten registration hereunder unless such person (i)
agrees to sell such person's Registrable Securities on the basis reasonably
provided in any underwriting arrangements approved by the persons entitled
hereunder to approve such arrangements and (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such

                                      -24-

underwriting arrangements.

      9. Miscellaneous.

            (a) Remedies. The Company acknowledges and agrees that any failure
      by the Company to comply with its obligations under this Agreement may
      result in material irreparable injury to the Initial Purchasers and the
      Holders for which there is no adequate remedy at law, that it will not be
      possible to measure damages for such injuries precisely and that, in the
      event of any such failure, any Initial Purchaser or Holder may obtain such
      relief as may be required to specifically enforce the Company's
      obligations under this Agreement. The Company further agrees to waive the
      defense in any action for specific performance that a remedy at law would
      be adequate. Notwithstanding the foregoing two sentences, this Section
      9(a) shall not apply to the subject matter referred to in and contemplated
      by Section 2(e).

            (b) No Conflicting Agreements. The Company is not, as of the date
      hereof, a party to, nor shall it, on or after the date of this Agreement,
      enter into, any agreement with respect to the Company's securities that
      conflicts with the rights granted to the Holders in this Agreement. The
      Company represents and warrants that the rights granted to the Holders
      hereunder are not in conflict with the rights granted to the holders of
      the Company's securities under any other agreements. The Company
      represents and covenants that it has not granted, and shall not grant, to
      any of its security holders (other than the Holders in such capacity) the
      right to include any of the Company's securities in any Shelf Registration
      Statement filed pursuant to this Agreement.

            (c) Amendments and Waivers. The provisions of this Agreement,
      including the provisions of this sentence, may not be amended, modified or
      supplemented, and waivers or consents to departures from the provisions
      hereof may not be given, unless the Company has obtained the written
      consent of Holders of a majority of outstanding Registrable Securities;
      provided, however, that, no consent is necessary from any of the Holders
      in the event that this Agreement is amended, modified or supplemented for
      the purpose of curing any ambiguity, defect or inconsistency that does not
      adversely affect the rights of any Holders. Notwithstanding the foregoing,
      a waiver or consent to depart from the provisions hereof with respect to a
      matter that relates exclusively to the rights of Holders of Registrable
      Securities whose securities are being sold pursuant to a Shelf
      Registration Statement and that does not directly or indirectly affect the
      rights of other Holders of Registrable Securities may be given by Holders
      of at least a majority of the Registrable Securities being sold by such
      Holders pursuant to such Shelf Registration Statement; provided, however,
      that the provisions of this sentence may not be amended, modified, or
      supplemented except in accordance with the provisions of the immediately
      preceding sentence. Each Holder of Registrable Securities outstanding at
      the time of any such amendment, modification, supplement, waiver or
      consent or thereafter shall be bound by any such amendment, modification,
      supplement, waiver or consent effected pursuant to this Section 9(c),
      whether or not any notice, writing or marking indicating such amendment,
      modification, supplement, waiver or consent appears on the Registrable
      Securities or is delivered to such Holder.

      in this Section 9(d) in writing in accordance herewith.

            (e) Majority of Registrable Securities. For purposes of determining
      what constitutes holders of a majority of Registrable Securities, as
      referred to in this Agreement, a majority shall constitute a majority in
      aggregate principal amount of Registrable Securities, treating each
      relevant holder of shares of Underlying Common Stock of the Notes as a
      holder of the aggregate principal amount of Notes in respect of which such
      Common Stock was issued.

            (f) Approval of Holders. Whenever the consent or approval of Holders
      of a specified percentage of Registrable Securities is required hereunder,
      Registrable Securities held by the Company or its "affiliates" (as such
      term is defined in Rule 405 under the Securities Act) (other than the
      Initial Purchasers or subsequent Holders of Registrable Securities, if the
      Initial Purchasers or such subsequent Holders are deemed to be such
      affiliates solely by reason of their holdings of such Registrable
      Securities) shall not be counted in determining whether such consent or
      approval was given by the Holders of such required percentage.

            (g) Third Party Beneficiaries. The Holders shall be third party
      beneficiaries to the agreements made hereunder between the Company, on the
      one hand, and the Initial Purchasers, on the other hand, and shall have
      the right to enforce such agreements directly to the extent they may deem
      such enforcement necessary or advisable to protect their rights or the
      rights of Holders hereunder. The Trustee shall be entitled to the rights
      granted to it pursuant to this Agreement and shall be bound by the terms
      hereof.

            (h) Successors and Assigns. Any person who purchases any Covered
      Security from any Initial Purchaser or from any Holder shall be deemed,
      for purposes of this Agreement, to be an assignee of such Initial
      Purchaser or such Holder, as the case may be. This Agreement shall inure
      to the benefit of and be binding upon the respective successors and
      assigns of each of the parties hereto and shall inure to the benefit of
      and be binding upon each Holder of any Covered Security.

            (i) Counterparts. This Agreement may be executed in any number of
      counterparts and by the parties hereto in separate counterparts, each of
      which when so executed shall be deemed to be original and all of which
      taken together shall constitute one and the same agreement.

            (j) Headings. The headings in this Agreement are for convenience of
      reference only and shall not limit or otherwise affect the meaning hereof.

            (k) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND
      CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT
      REGARD TO CONFLICTS OF LAWS PRINCIPLES THEREOF.

            (l) Severability. If any term, provision, covenant or restriction of
      this

                                      -27-

<PAGE>

      Agreement is held to be invalid, illegal, void or unenforceable, the
      remainder of the terms, provisions, covenants and restrictions set forth
      herein shall remain in full force and effect and shall in no way be
      affected, impaired or invalidated thereby, and the parties hereto shall
      use their reasonable best efforts to find and employ an alternative means
      to achieve the same or substantially the same result as that contemplated
      by such term, provision, covenant or restriction, it being intended that
      all of the rights and privileges of the parties shall be enforceable to
      the fullest extent permitted by law.

            (m) Entire Agreement. This Agreement is intended by the parties
      hereto as a final expression of their agreement and is intended to be a
      complete and exclusive statement of the agreement and understanding of the
      parties hereto in respect of the subject matter contained herein and the
      registration rights granted by the Company with respect to the Registrable
      Securities. Except as provided in the Purchase Agreement, there are no
      restrictions, promises, warranties or undertakings, other than those set
      forth or referred to herein, with respect to the registration rights
      granted by the Company with respect to the Registrable Securities. This
      Agreement supersedes all prior agreements and undertakings among the
      parties with respect to such registration rights. No party hereto shall
      have any rights, duties or obligations other than those specifically set
      forth in this Agreement.

            (n) Termination. This Agreement and the obligations of the parties
      hereunder shall terminate upon the end of the Effectiveness Period, except
      for any liabilities or obligations under Section 4, Section 5 or Section 6
      hereof and the obligations to make payments of and provide for additional
      interest under Section 2(e) hereof to the extent such additional interest
      accrues prior to the end of the Effectiveness Period and to the extent any
      overdue additional interest accrues in accordance with the last paragraph
      of such Section 2(e), each of which shall remain in effect in accordance
      with its terms.

            (o) Submission to Jurisdiction. Except as set forth below, no
      proceeding, claim, counterclaim or dispute of any kind or nature
      whatsoever arising out of or in any way relating to this Agreement
      ("Claim") may be commenced, prosecuted or continued in any court other
      than the courts of the State of New York located in the City and County of
      New York or in the United States District Court for the Southern District
      of New York, which courts shall have jurisdiction over the adjudication of
      such matters, and the Company hereby consents to the jurisdiction of such
      courts and personal service with respect thereto. The Company hereby
      consents to personal jurisdiction, service and venue in any court in which
      any Claim arising out of or in any way relating to this Agreement is
      brought by any third party against any Initial Purchaser. THE COMPANY,
      EACH INITIAL PURCHASER AND EACH HOLDER HEREBY WAIVE ALL RIGHTS TO TRIAL BY
      JURY IN ANY PROCEEDING (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) IN
      ANY WAY ARISING OUT OF OR RELATING TO THIS AGREEMENT. The Company, each
      Initial Purchaser and each Holder agree that a final judgment in any such
      Proceeding brought in any such court shall be conclusive and binding upon
      the Company, such Initial Purchaser or such Holder, as applicable, and may
      be enforced in any other courts in the jurisdiction of which the Company,
      such Initial Purchaser or such Holder, as applicable, is or may be
      subject, by

Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Senior Notes have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other

within the terms established in the applicable Argentine regulations. In any
case where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. Where this
Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

     In addition, the Company and any Subsidiary Guarantor shall be required to
cause all such other communications to the CNV and the BASE and all such other

this Indenture. Notwithstanding the foregoing, any suit, action or proceeding
brought in connection with this Indenture or the Senior Notes may be instituted
in any competent court in Argentina.

     (b) To the extent that the Company or any Subsidiary Guarantor may be
entitled to the benefit of any provision of law requiring the Trustee or any
Holder of the Senior Notes, in any suit, action or proceeding brought in a court
of Argentina or other jurisdiction arising out of or in connection with any of
this Indenture or the Senior Notes, to post security for litigation costs or
otherwise post a performance bond or guaranty ("CAUTIO JUDICATUM SOLVI" or
"EXCEPCION DE ARRAIGO"), or to take any similar action, the Company and any
Subsidiary Guarantor will waive such benefit, in each case to the fullest extent
permitted under the laws of Argentina or, as the case may be, such other
jurisdiction.

     (c) The Company agrees that service of all writs, process and summonses in
any suit, action or proceeding brought in connection with this Indenture or the
Senior Notes against the Company, as the case may be, in any court of the State
of New York or any United States federal court sitting in the Borough of
Manhattan, New York City may be made upon CT Corporation System at 1633
Broadway, New York, New York 10019, whom each of the Company has, and any
Subsidiary Guarantor shall have, irrevocably appointed as its authorized agent
for service of process. The Company represents and warrants that CT Corporation
System has agreed to act as the agent for service of process for the Company.
The Company agrees that such appointment shall be irrevocable so long as any of
the Senior Notes remain outstanding or until the irrevocable appointment by the
Company and any Subsidiary Guarantor, as the case may be, of a successor in The
City of New York as its authorized agent for such purpose and the acceptance of
such appointment by such successor. The Company further agrees to take any and
all action, including the filing of any and all documents and instruments, that
may be necessary to continue such appointment in full force and effect as
aforesaid. If CT Corporation

                                       36

System shall cease to act as the agent for service of process for the Company,
the Company shall appoint without delay another such agent and provide prompt
written notice to the Trustee of such appointment. With respect to any such
action in any court of the State of New York or any United States federal court
in the Borough of Manhattan, New York City, service of process upon CT
Corporation System, as the authorized agent of the Company for service of
process, and written notice of such service to the Company shall be deemed, in
every respect, effective service of process upon the Company.

     (d) Nothing in this Section shall affect the right of any party to serve
legal process in any other manner permitted by law or affect the right of any
party to bring any action or proceeding against any other party or its property
in the courts of other jurisdictions.

     SECTION 1.13. Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date, sinking fund
payment date or Stated Maturity or Maturity of any Senior Note shall not be a
Business Day, then (notwithstanding any other provision of this Indenture or of
the Senior Notes) payment of principal (or premium, if any) or interest need not
be made on such date, but may be made on the next succeeding Business Day with
the same force and effect as if made on the Interest Payment Date, Redemption
Date or sinking fund payment date, or at the Stated Maturity or Maturity;
provided that no interest shall accrue with respect to such payment on account
of such delay for the period from and after such Interest Payment Date,
Redemption Date, sinking fund payment date, Stated Maturity or Maturity, as the
case may be.

     SECTION 1.14. No Personal Liability of Incorporators, Shareholders,
Officers, Directors or Employees.

     No recourse for the payment of the principal of or premium, if any, or
interest or Liquidated Damages or Additional Amounts, if any, on any of the
Senior Notes or for any claim based thereon or otherwise in respect thereof, and
no recourse under or upon any obligation, covenant or agreement of the Company
in the Indenture, any supplemental indenture, or in any of the Senior Notes or
because of the creation of any Indebtedness represented thereby, shall be had
against any incorporator, shareholder, officer, director, employee or
controlling person of the Company or of any successor Person thereof, whether by
virtue of any constitution, statute or rule of law or by the enforcement of any
amendment or penalty or otherwise. Each Holder, by accepting the Senior Notes,
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Senior Notes. Such waiver may not be effective
to waive liabilities under Article 34 of the Argentine Negotiable Obligations
Law, Article 34 of Law No. 19,550, as amended, and other Argentine regulations
or under the U.S. federal securities laws and it is the view of the Commission
that such a waiver is against public policy.

     MASTELLONE HERMANOS S.A., a sociedad anonima duly organized and existing
under the laws of the Republic of Argentina (herein called the "COMPANY", which
term includes any successor Person under the Indenture hereinafter referred to),
for value received, hereby promises to pay to ________________ or registered

office or agency of the Company referred to below, and to pay interest thereon
on October 1, 1998 and semiannually thereafter, on April 1 and October 1 of each

of 11.75% per annum, until the principal hereof is paid or duly provided for,
and (to the extent lawful) to pay on demand interest on any overdue interest at

registered at the close of business on the Regular Record Date for such
interest, which shall be the March 15 or September 15 (whether or not a Business
Day), as the case may be, next preceding such Interest Payment Date. Any such
interest not so punctually paid or duly provided for shall forthwith cease to be

and (to the extent lawful) interest on such defaulted interest at the rate borne
by the Senior Notes, may be paid to the Person in whose name this Note (or one
or more Predecessor Senior Notes) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Senior Notes not less
than 10 days prior to such Special Record Date, or may be paid at any time in
any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in said Indenture.

     The principal of this Note (including any Additional Amounts under Section

Senior Note, any Liquidated Damages under Section 5 of the Registration Rights
Agreement hereinafter referred to) shall be payable at the Corporate Trust
Office of The Bank of New York in The City of New York and at the office of
Banco Rio de la Plata S.A. in the City of Buenos Aires and, subject to any
fiscal or other laws and regulations applicable thereto, at the specified
offices of any other Paying Agents appointed by the Company. Payments of
principal of this Note shall be made against surrender of this Note. Payments in
respect of interest (including Additional Amounts and Liquidated Damages, if
any) on each Interest Payment Date with respect to this Note will be made to the
Person in whose name such Note is registered on the Regular Record Date
immediately preceding such Interest Payment Date by US Dollar check drawn on a
bank in The City of New York or, in case of the holder of at least US$1,000,000
principal amount of

administrative costs imposed by banks in connection with making payments by wire
transfer.

     SECTION 2.05. Form of Reverse of Senior Note.

     This Note is a negotiable obligation under the Argentine Negotiable
Obligations Law and is one of a duly authorized issue of securities of the
Company designated as its [Series A/Series B] 11 3/4% Senior Notes due 2008
(herein called the "SENIOR NOTES"), limited (except as otherwise provided in the
Indenture referred to below) in aggregate principal amount to $225,000,000,
which may be issued under an indenture (herein called the "INDENTURE") dated as
of March 31, 1998 among the Company, and The Bank of New York, as trustee
(herein called the "TRUSTEE", which term includes any successor trustee under
the Indenture), Co-Registrar and Principal Paying Agent, and Banco Rio de la
Plata S.A., as Registrar and Paying Agent, to which Indenture and all indentures

                                       43

supplemental thereto reference is hereby made for a statement of the respective
rights; limitations of rights, duties, obligations and immunities thereunder of
the Company, the Trustee and the Holders of the Senior Notes, and of the terms
upon which the Senior Notes are, and are to be, authenticated and delivered.

     The Senior Notes will be redeemable, at the Company's option, in whole or
in part, at any time or from time to time, on or after April 1, 2003, and prior
to maturity, upon not less than 30 nor more than 60 days' prior notice, at the
following redemption prices (expressed in percentages of principal amount), plus
accrued and unpaid interest, including Liquidated Damages and Additional
Amounts, if any, to the redemption date, if redeemed during the 12-month period
commencing April 1 of the years set forth below:

        YEAR                                                REDEMPTION PRICE
        ----                                                ----------------
        2003                                                   105.875%
        2004                                                   103.917%
        2005                                                   101.958%
        2006 and thereafter                                    100.000%

     At any time on or prior to April 1, 2001, the Company may redeem up to 35%
of the original aggregate principal amount of the Senior Notes within 60 days
after any sale (other than to a Restricted Subsidiary) of Capital Stock (other
than Redeemable Capital Stock) of the Company with the net proceeds of such sale
at a redemption price equal to 111.75% of the principal amount thereof, together
with accrued interest, if any, to the Redemption Date (subject to the right of
holders of record on relevant record dates to receive interest due on relevant
Interest Payment Dates), provided that no less than US$100 million aggregate
principal amount of the Senior Notes remains outstanding immediately after the
occurrence of any such redemption. Any such redemption shall be made on a pro
rata basis among all holders of Senior Notes.

     If at any time after the Original Issue Date and prior to April 1, 2003 as
a result of any change in, or amendment to, the laws or regulations or rulings
promulgated thereunder of Argentina or of any political subdivision thereof or
of any authority therein or thereof having power to tax or as a result of any
change in the application or official interpretation of such laws or regulations
or rulings, including without limitation a holding of a court of competent
jurisdiction, which change, amendment, application or interpretation becomes
effective after the Original Issue Date (a "CHANGE IN LAW"), the Company becomes
obligated to pay any Additional Amounts (as hereinafter provided) or any taxes
imposed pursuant to the Personal Asset Tax Law of Argentina, as amended from
time to time, and as modified by governmental decree or otherwise ("PERSONAL
ASSET TAXES"), and such obligation cannot be avoided by the Company taking
reasonable measures available to it, then the Senior Notes will be redeemable as
a whole (but not in part), at the option of the Company, at any time upon not
less than thirty (30) days nor more than sixty (60) days' notice given to the
holders as provided in the Indenture at 111.75% of their principal amount
together with accrued interest thereon to the Redemption Date. The Company will
also pay to the holders on the Redemption Date any Additional Amounts which are
then payable. In order to effect such a redemption of the Senior Notes, the
Company will be required to deliver to the Trustee at least

                                       44

forty-five (45) days prior to the Redemption Date an officer's certificate to
the effect that the Company's obligation to pay Additional Amounts or Personal
Asset Taxes, as the case may be, cannot be avoided by the Company taking
reasonable measures available to it and an opinion of independent legal counsel
of recognized standing to the effect that the Company has or will become
obligated to pay such Additional Amounts or Personal Asset Taxes, as the case
may be, as a result of such Change in Law as a result of such Change in Law. No
notice of redemption may be given earlier than sixty (60) days prior to the
earliest date on which the Company would be obligated to pay such Additional
Amounts or Personal Asset Taxes (as the case may be) were a payment in respect
of the Senior Notes then due.

     Upon the occurrence of a Change in Control, the Holder of this Note may
require the Company, subject to certain limitations provided in the Indenture,
to repurchase this Note at a purchase price in cash in an amount equal to 101 %
of the principal amount thereof plus accrued and unpaid interest, if any, in
accordance with the Indenture.

     In the case of any redemption of Senior Notes, interest installments whose
Stated Maturity is on or prior to the Redemption Date will be payable to the
Holders of such Senior Notes, or one or more Predecessor Senior Notes, of record
at the close of business on the relevant Record Date referred to on the face
hereof. Senior Notes (or portions thereof) for whose redemption and payment
provision is made in accordance with the Indenture shall cease to bear interest
from and after the Redemption Date.

     In the event of redemption of this Note in part only, a new Note or Senior
Notes for the unredeemed portion hereof shall be issued in the name of the
Holder hereof upon the cancellation hereof.

     If an Event of Default shall occur and be continuing, the principal of all
the Senior Notes may be declared due and payable in the manner and with the
effect provided in the Indenture.

     The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Company on this Note and (b) certain restrictive
covenants and the related Defaults and Events of Default, upon compliance by the
Company with certain conditions set forth therein, which provisions apply to
this Note.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of a majority in
aggregate principal amount of the Senior Notes at the time Outstanding. The
Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Senior Notes at the time
Outstanding, on behalf of the Holders of all the Senior Notes, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by or on behalf of the Holder of this Note shall be conclusive and
binding upon such Holder and upon all future Holders of this Note and of any
Note issued upon the registration of

                                       45

transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest and Additional Amounts and Liquidated Damages, if any on this Note at
the times, place, and rate, and in the coin or currency, herein prescribed.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, or interest or
Additional Amounts or Liquidated Damages, if any, on any Senior Note and
remaining unclaimed for three years after such principal or interest or
Additional Amounts or Liquidated Damages, if any, has become due and payable
shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Senior Note
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, (i) in a newspaper published
in the English language, customarily published on each Business Day and of
general circulation in The Borough of Manhattan, City of New York, and (ii) in a
newspaper published in the Spanish language and of general circulation in
Argentina, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than thirty (30) days from the date
of such publication, any unclaimed balance of such money then remaining shall be
repaid to the Company.

     If the due date for payment of any principal or interest in respect of any
Senior Note is not a Business Day at the place in which it is presented for
payment, the Holder thereof will not be entitled to payment of the amount due
until the next succeeding Business Day at such place and will not be entitled to
any further interest or other payment in respect of any such delay.

     In the event of any foreign exchange restriction or prohibition in
Argentina, any and all payments in respect of the Senior Notes shall be made, to
the extent permitted by such restriction or prohibition, in US Dollars through
(i) the sale of Bonex or of any other public or private bond issued in US
Dollars in Argentina or (ii) any other legal mechanism for the acquisition of US
Dollars in any exchange market. All costs, including any taxes, relative to such
operations to obtain US Dollars shall be borne by the Company.

     The Company or any of its Subsidiaries may at any time or from time to time
purchase Senior Notes in the open market, or by tender or by private agreement
at any price. Any purchase by tender shall be made available to all Holders of
Senior Notes alike. All Senior Notes so purchased may be held for the account of
the Company or may be resold by the Company or may be cancelled by the Company.

                                       46

     Unless otherwise required by law, all payments made by the Company or any
Subsidiary Guarantor will be made without withholding or deduction for or on
account of any present or future taxes, duties, assessments or governmental
charges or penalties and interest related thereto ("TAXES") of whatever nature
imposed, levied, collected, withheld or assessed by or within Argentina or any
authority therein or thereof or having power to tax. In the event any such Taxes
are so imposed on any payments made by the Company or any such Subsidiary
Guarantor, the Company or such Subsidiary Guarantor, as the case may be, will
pay such Additional Amounts as may be necessary in order that the net amounts
received by each Holder (including Additional Amounts and Liquidated Damages)
after any withholding or deduction in respect of such Taxes shall equal the
respective amounts of principal, premium, if any, and interest that would have
been received in respect of the Senior Notes in the absence of such withholding
or deduction; except that no such Additional Amounts will be payable with
respect to any withholding or deduction in respect of any payment under a Senior
Note or a Subsidiary Guarantee to, or to a third party on behalf of, a Holder
for or on account of any such Taxes imposed by reason of (i) the Holder being a
resident of Argentina or having some connection with Argentina (or any political
subdivision or authority thereof) other than the mere holding of such Senior
Note or Subsidiary Guarantee or the receipt of any payment thereunder or the
exercise of rights under the Senior Notes, the Subsidiary Guarantee, if any, or
the Indenture; (ii) if presentation is required in respect of a Senior Note or a
Subsidiary Guarantee, by reason of presentation by the Holder for payment on a
date more than thirty (30) days after the date on which such payment first
became due and payable or the date on which such payment is duly provided,
whichever occurs later, except to the extent that the Holder would have been
entitled to such Additional Amounts on presenting such Senior Note or Subsidiary
Guarantee for payment on the last date of such period of thirty (30) days; (iii)
any estate, asset (other than Personal Asset Taxes as defined in the Indenture),
inheritance, gift, sales or transfer tax or similar tax assessment or
governmental charge; (iv) any tax, assessment or other governmental charge
(other than Personal Asset Taxes as defined in the Indenture) which is payable
otherwise than by withholding from payments on or in respect of any Senior Note;
or (v) any combination of the reasons set forth in clauses (i), (ii), (iii) or
(iv) above. Furthermore, no Additional Amounts shall be paid to a Holder that is
a fiduciary or partnership or other than the sole beneficial owner of such
payment to the extent that a beneficiary or settlor with respect to such
fiduciary or a member of such partnership or beneficial owner would not have
been entitled to receive the Additional Amounts had such beneficiary, settlor,
member or beneficial owner been the Holder.

     At least 30 calendar days prior to each date on which any payment under or
with respect to the Senior Notes is due and payable, if the Company or any
Subsidiary Guarantor, as applicable, will be obligated to pay Additional Amounts
with respect to such payment, the Company or such Subsidiary Guarantor will
deliver to the Trustee an Officers' Certificate stating the fact that such
Additional Amounts will be payable and the amounts so payable and will set forth
such other information necessary to enable the Trustee to pay such Additional
Amounts to Holders on the payment date and specifying the amount required to be
deducted or withheld on the payments of principal and interest (and premium, if
any) due on such payment date for or on account of Taxes and certifying that
such amount will be deducted or withheld and paid by the Company or

                                       47

Subsidiary Guarantor, as the case may be, to the appropriate taxing or
governmental authority. The Company has agreed to indemnify each of the Trustee,
the Principal Paying Agent and each other paying agent for, and to hold it
harmless against any loss, liability, or expense incurred without negligence,
bad faith or wilful misconduct on its part, arising out of or in connection with
actions taken or omitted by it in reliance on any certificate furnished pursuant
to this paragraph or the failure to furnish such a certificate. The obligations
of the Company under this paragraph shall survive the payment of the Senior
Notes and the resignation or removal of the Trustee, the Principal Paying Agent
or any other paying agent and the termination of this Indenture. Whenever in the
Indenture there is mentioned, in any context, the payment of principal, premium,
if any, interest, Liquidated Damages, if any or any other amount payable, under
or with respect to any Senior Note or Subsidiary Guarantee, such mention shall
be deemed to include mention of the payment of Additional Amounts to the extent
that, in such context, Additional Amounts are payable in respect thereof.

     If the Company is held liable for any Personal Asset Taxes (as defined in
the Indenture) imposed on the Holders or direct owners of Senior Notes with
respect to the Senior Notes, the Company waives any right that it may have as a
matter of Argentine law to seek reimbursement from such Holders or direct owners
of Senior Notes for any such Personal Asset Taxes paid.

     In addition, the Company will pay any stamp, issue, registration,
documentary or other similar taxes and duties, including interest and penalties,
payable in Argentina or the United States or any political subdivision thereof
or taxing authority thereof or in the foregoing in respect of the creation,
issue and offering of the Senior Notes, and will pay any court, documentary or
similar taxes and duties required to be paid in connection with the enforcement
of the Senior Notes following the incurrence of any Event of Default.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable on the Note Register of the
Company, upon surrender of this Note for registration of transfer at the office
or agency of the Registrar or Co-Registrar maintained for such purpose in the
City of Buenos Aires and The City of New York, respectively, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Company duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Senior Notes, of authorized denominations
and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

     The Senior Notes are issuable only in registered form without coupons in
denominations of US$1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Senior Notes
are exchangeable for a like aggregate principal amount of Senior Notes of a
different authorized denomination, as requested by the Holder surrendering the
same.

     No service charge shall be made for any registration of transfer or
exchange of Senior Notes, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.

                                       48

     Prior to the time of due presentment of this Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Note is registered as the owner hereof
for all purposes, whether or not this Note shall be overdue, and neither the
Company, the Trustee nor any agent shall be affected by notice to the contrary.

     No recourse shall be had for the payment of the principal of, premium, if
any, or the interest on this Note, for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture or any indenture
supplemental thereto, against any incorporator, shareholder, officer or
director, as such, past, present or future, of the Company or any Subsidiary
Guarantor or of any successor corporation, either directly or through the
Company, any Subsidiary Guarantor or any successor corporation, whether by
virtue of any constitution, statute or rule of law or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issue hereof, expressly waived
and released, with the understanding, however, that this provision shall not
limit in any manner the rights concerning the holders of Senior Notes under
Section 34 of the Argentine Negotiable Obligations Law.

     In addition to the rights provided to Holders of the Senior Notes under the
Indenture, Holders of Series A Senior Notes constituting Transfer Restricted
Securities (as defined in the Registration Rights Agreement) shall have all the
rights set forth in the Registration Rights Agreement dated as of the Original
Issue Date by and between the Company, on the one hand, and the Initial
Purchaser, on the other hand, providing for certain registration rights for the
Series A Senior Notes (the "REGISTRATION RIGHTS AGREEMENT").

     All terms used in this Note which are defined in the Indenture shall have
the meanings assigned to them in the Indenture.

     The Trustee will furnish to any Holder of any Senior Note upon written
request and without charge, a copy of the Indenture. Requests may be directed
to: The Bank of New York, 101 Barclay Street, Floor 21 West, New York, New York
10286.

                                THE SENIOR NOTES

     SECTION 3.01. Title and Terms.

     The aggregate principal amount of Senior Notes which may be authenticated
and delivered under this Indenture is limited to $225,000,000, except for Senior
Notes authenticated and delivered upon registration of transfer of, or in
exchange for, or in lieu of, other Senior Notes pursuant to Section 3.04, 3.05,
3.06, 9.06, 10.15, 10.16 or 11.08 or pursuant to the Exchange Offer.

     The Senior Notes shall be known and designated as the "Series A 11 3/4%
Senior Notes due 2008" and the "Series B 11 3/4% Senior Notes due 2008", as the
case may be, of the Company. Their Stated Maturity shall be April 1, 2008, and
they shall bear interest at the rate of 11.75% per annum from March 31, 1998, or
from the most recent Interest Payment Date to which interest has been paid or
duly provided for, payable on October 1, 1998 and semiannually thereafter on
April 1 and October 1 of each year and at said Stated Maturity, until the
principal thereof is paid or duly provided for.

     The principal of and interest and Additional Amounts and Liquidated
Damages, if any, on the Senior Notes shall be payable at the Corporate Trust
Office of the Principal Paying Agent in The City of New York and at the office
of the Paying Agent, in the City of Buenos Aires and, subject to fiscal or other
laws and regulations applicable thereto, specified offices of any other Paying
Agent appointed by the Company for such purpose; provided, however, that at the
option of the Company payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the Note
Register or, in the case of a holder of at least US$1,000,000 principal amount
of Senior Notes, by wire transfer to a US Dollar account maintained by the payee
with a bank in the United States or in Argentina, provided that the Holder so
elects by giving written notice to such effect designating such account with
appropriate wire transfer instructions which is received by the Principal Paying
Agent no later than the Regular Record Date immediately preceding such Interest
Payment Date. Unless such designation is revoked, any such designation made by
such Holder with respect to such Senior Notes will remain in effect with respect
to any future payments with respect to such Senior Note payable to such Holder.

     In the event of any foreign exchange restriction or prohibition in
Argentina, any and all payments in respect of the Securities shall be made, to
the extent permitted by such restriction or prohibition, in US Dollars through
(i) the sale of Bonex or of any other public or private bond issued in US
Dollars in Argentina or (ii) any other legal mechanism for the acquisition of US
Dollars in any exchange market. All costs, including any taxes, relative to such
operations to obtain US Dollars shall be borne by the Company.

     Unless otherwise required by law, all payments made by the Company or any
Subsidiary Guarantor will be made without withholding or deduction for or on
account of

                                       53

any present or future taxes, duties, assessments or governmental charges or
penalties and interest related thereto ("TAXES") of whatever nature imposed,
levied, collected, withheld or assessed by or within Argentina or any authority
therein or thereof or having power to tax. In the event any such Taxes are so
imposed on any payments made by the Company or any such Subsidiary Guarantor,
the Company or such Subsidiary Guarantor, as the case may be, will pay such
Additional Amounts as may be necessary in order that the net amounts received by
each Holder (including Additional Amounts and Liquidated Damages) after any
withholding or deduction in respect of such Taxes shall equal the respective
amounts of principal, premium, if any, and interest that would have been
received in respect of the Senior Notes in the absence of such withholding or
deduction; except that no such Additional Amounts will be payable with respect
to any withholding or deduction in respect of any payment under a Senior Note or
a Subsidiary Guarantee to, or to a third party on behalf of, a Holder for or on
account of any such Taxes imposed (i) by reason of the Holder being a resident
of Argentina or having some connection with Argentina (or any political
subdivision or authority thereof) other than the mere holding of such Senior
Note or Subsidiary Guarantee or the receipt of any payment thereunder or the
exercise of rights under the Senior Notes, the Subsidiary Guarantee, if any, or
the Indenture; (ii) if presentation is required in respect of a Senior Note or a
Subsidiary Guarantee, by reason of presentation by the Holder for payment on a
date more than thirty (30) days after the date on which such payment first
became due and payable or the date on which such payment is duly provided,
whichever occurs later, except to the extent that the Holder would have been
entitled to such Additional Amounts on presenting such Senior Note or Guarantee
for payment on the last date of such period of thirty (30) days; (iii) any
estate, asset (other than Personal Asset Taxes), inheritance, gift, sales or
transfer tax or similar tax assessment or governmental charge; (iv) any tax,
assessment or other governmental charge (other than Personal Asset Taxes) which
is payable otherwise than by withholding from payments on or in respect of any
Senior Note; or (v) any combination of the reasons set forth in clauses (i),
(ii), (iii) or (iv) above. Furthermore, no Additional Amounts shall be paid to a
Holder that is a fiduciary or partnership or other than the sole beneficial
owner of such payment to the extent that a beneficiary or settlor with respect
to such fiduciary or a member of such partnership or beneficial owner would not
have been entitled to receive the Additional Amounts had such beneficiary,
settlor, member or beneficial owner been the Holder.

     At least 30 calendar days prior to each date on which any payment under or
with respect to the Senior Notes is due and payable, if the Company or any
Subsidiary Guarantor, as applicable, will be obligated to pay Additional Amounts
with respect to such payment, the Company or such Subsidiary Guarantor will
deliver to the Trustee an Officers' Certificate stating the fact that such
Additional Amounts will be payable and the amounts so payable and will set forth
such other information necessary to enable the Trustee to pay such Additional
Amounts to holders on the payment date and specifying the amount required to be
deducted or withheld on the payments of principal and interests (and premium, if
any) due on such payment date for or on account of Taxes and certifying that
such amount will be deducted or withheld and paid by the Company or Subsidiary
Guarantor, as the case may be, to the appropriate taxing or governmental
authority. The Company hereby agrees to indemnify each of the Trustee, the
Principal Paying Agent and each other paying agent for, and to hold it harmless
against any loss,

                                       54

liability, or expense incurred without negligence, bad faith or willful
misconduct on its part, arising out of or in connection with actions taken or
omitted by it in reliance on any certificate furnished pursuant to this Section
or the failure to furnish such a certificate. The obligations of the Company
under this Section shall survive the payment of the Senior Notes and the
resignation or removal of the Trustee, the Principal Paying Agent or any other
paying agent and the termination of this Indenture. Whenever in the Indenture
there is mentioned, in any context, the payment of principal, premium, if any,
interest, Liquidated Damages, if any, or any other amount payable, under or with
respect to any Senior Note or Guarantee, such mention shall be deemed to include
mention of the payment of Additional Amounts to the extent that, in such
context, Additional Amounts are payable in respect thereof.

     If the Company is held liable for any Personal Asset Taxes imposed on the
Holders or direct owners of Senior Notes with respect to the Senior Notes, the
Company hereby agrees to waive any right that it may have as a matter of
Argentine law to seek reimbursement from such Holders or direct owners of Senior
Notes for any such Personal Asset Taxes paid.

     In addition, the Company will pay any stamp, issue, registration,
documentary or other similar taxes and duties, including interest and penalties,
payable in Argentina or the United States or any political subdivision thereof
or taxing authority thereof or in the foregoing in respect of the creation,
issue and offering of the Senior Notes, and will pay any court, documentary or
similar taxes and duties required to be paid in connection with the enforcement
of the Senior Notes following the incurrence of any Event of Default.

     The Senior Notes shall be redeemable as provided in Article Eleven.

     SECTION 3.02. Denominations.

     The Senior Notes shall be issuable only in registered non-endorsable form
without coupons and only in denominations of $1,000 and any integral multiple
thereof.

     SECTION 3.03. Execution, Authentication, Delivery and Dating.

     The Senior Notes shall be executed on behalf of the Company by a member of
the Supervisory Committee of the Company and by a Director of the Company. The
signature of any of these officers on the Senior Notes may be manual or, subject
to the applicable regulations of the CNV, facsimile signatures of the present or
any future such authorized officer and may be imprinted or otherwise reproduced
on the Senior Notes.

     Senior Notes bearing the manual or facsimile signatures of individuals who
were at any time a member of the Supervisory Committee and a Director of the
Company shall bind the Company, notwithstanding that such individuals or any of
them have ceased to hold such offices prior to the authentication and delivery
of such Senior Notes or did not hold such offices at the date of such Senior
Notes.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Senior Notes executed by the Company to the

                                       55

Trustee for authentication, together with a Company Order for the authentication
and delivery of such Senior Notes, directing the Trustee to authenticate the
Senior Notes and certifying that all conditions precedent to the issuance of
Senior Notes contained herein have been fully complied with, and the Trustee in
accordance with such Company Order shall authenticate and deliver such Senior
Notes. In each case, the Trustee shall be entitled to receive an Officers'
Certificate and an Opinion of Counsel of the Company stating that the issuance
and authentication of such Senior Notes complies with this Indenture and all
other relevant law, supplemented by such other representations and warranties as
the Trustee may reasonably request in connection with such authentication of
Senior Notes. Such order shall specify the amount of Senior Notes to be
authenticated and the date on which the original issue of Senior Notes is to be
authenticated.

     Each Senior Note shall be dated the date of its authentication.

     No Senior Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Senior Note a
certificate of authentication substantially in the form provided for herein duly
executed by the Trustee by manual signature of an authorized signatory, and such
certificate upon any Senior Note shall be conclusive evidence, and the only
evidence, that such Senior Note has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture.

     In case the Company, pursuant to Article Eight, shall be consolidated or
merged with or into any other Person or shall convey, transfer, lease or
otherwise dispose of its properties and assets substantially as an entirety to
any Person, and the successor Person resulting from such consolidation, or
surviving such merger, or into which the Company shall have been merged, or the
Person which shall have received a conveyance, transfer, lease or other
disposition as aforesaid, shall have executed an indenture supplemental hereto
with the Trustee pursuant to Article Eight, any of the Senior Notes
authenticated or delivered prior to such consolidation, merger, conveyance,
transfer, lease or other disposition may, from time to time, at the request of
the successor Person, be exchanged for other Senior Notes executed in the name
of the successor Person with such changes in phraseology and form as may be
appropriate, but otherwise in substance of like tenor as the Senior Notes
surrendered for such exchange and of like principal amount; and the Trustee,
upon Company Request of the successor Person, shall authenticate and deliver
Senior Notes as specified in such request for the purpose of such exchange. If
Senior Notes shall at any time be authenticated and delivered in any new name of
a successor Person pursuant to this Section in exchange or substitution for or
upon registration of transfer of any Senior Notes, such successor Person, at the
option of the Holders but without expense to them, shall provide for the
exchange of all Senior Notes at the time Outstanding for Senior Notes
authenticated and delivered in such new name.

     SECTION 3.04. Temporary Senior Notes.

     Pending the preparation of definitive Senior Notes, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Senior Notes which are printed, lithographed, typewritten,
mimeographed or otherwise

                                       56

produced, in any authorized denomination, substantially of the tenor of the
definitive Senior Notes in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Senior Notes may determine, as conclusively evidenced by
their execution of such Senior Notes.

     If temporary Senior Notes are issued, the Company will cause definitive
Senior Notes to be prepared without unreasonable delay. After the preparation of
definitive Senior Notes, the temporary Senior Notes shall be exchangeable for
definitive Senior Notes upon surrender of the temporary Senior Notes at the
office or agency of the Company designated for such purpose pursuant to Section
10.02, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Senior Notes, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Senior Notes of authorized denominations. Until so exchanged, the
temporary Senior Notes shall in all respects be entitled to the same benefits
under this Indenture as definitive Senior Notes.

     SECTION 3.05. Registration, Registration of Transfer and Exchange.

     Subject to any applicable laws and such reasonable regulations as it may
prescribe, Banco Rio de la Plata S.A., as Registrar, shall keep a register (the
"NOTE REGISTER") at its registrar offices in Buenos Aires, Argentina set forth
in Section 1.05 of this Indenture for the registration of ownership, exchange,
and transfer of the Senior Notes. The Bank of New York, as Co-Registrar, shall
also maintain a record of all registrations of ownership, exchange and transfer
of Senior Notes. The Co-Registrar shall give prompt written notice to the
Registrar and the Registrar shall likewise give prompt written notice to the
Co-Registrar of any registration of ownership, exchange or transfer of Senior
Notes. Included in the books and records for the Senior Notes shall be notations
as to whether such Senior Notes have been paid, exchanged or transferred and
canceled or lost, stolen, mutilated or destroyed and whether such Senior Notes
have been replaced. In the case of the replacement of any of the Senior Notes,
the Registrar and the Co-Registrar shall keep a record of the Senior Note so
replaced and the Senior Note issued in replacement thereof. In the case of the
cancellation of any of the Senior Notes, the Registrar and the Co-Registrar
shall keep a record of the Senior Note so canceled and the date on which such
Senior Note was canceled.

     Upon presentation for exchange or transfer of any Senior Note at the office
of either the Registrar or Co-Registrar accompanied by a written instrument of
exchange or transfer in a form approved by the Company duly executed by the
registered Holder or his attorney-in-fact duly authorized in writing, and upon
completion of any certification required by the terms of this Indenture, such
Senior Note shall be exchanged or transferred upon the Note Register, and one or
more new Senior Notes shall be authenticated and issued in the name of the
Holder (in the case of exchanges only) or the transferee, as the case may be. No
exchange or transfer of a Senior Note shall be effective under this Indenture or
the Senior Notes unless and until such Senior Note has been registered in the
name of such Person in the Note Register. Furthermore, the exchange or transfer
of any Senior Note shall not be effective under this Indenture or the Senior
Notes unless the request for such exchange or transfer is made by the registered

                                       57

Holder or by a duly authorized attorney-in-fact at the office of the Registrar
or the Co-Registrar.

     Furthermore, any Holder of any Global Senior Note shall, by acceptance of
such Global Senior Note, agree that transfers of beneficial interest in such
Global Senior Note may be effected only through a book-entry system maintained
by the Holder of such Global Senior Note (or its agent), and that ownership of a
beneficial interest in the Senior Note shall be required to be reflected in a
book entry.

     At the option of the Holder, Senior Notes may be exchanged for other Senior
Notes of any authorized denomination and of a like aggregate principal amount,
upon surrender of the Senior Notes to be exchanged at such office or agency.
Whenever any Senior Notes are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Senior Notes which
the Holder making the exchange is entitled to receive.

     All Senior Notes issued upon any registration of transfer or exchange of
Senior Notes shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Senior
Notes surrendered upon such registration of transfer or exchange.

     Every Senior Note presented or surrendered for registration of transfer or
for exchange shall be duly endorsed, or (if so required by the Company) be
accompanied by a written instrument of transfer, in form satisfactory to the
Company, duly executed by the Holder thereof or his attorney duly authorized in
writing.

     No service charge shall be made for any registration of transfer or
exchange or redemption of Senior Notes, except for the expense of delivery other
than by regular mail (if any) and except that the Company may require payment of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of Senior
Notes, other than exchanges pursuant to Section 3.04, 9.06, 10.15, 10.16 or
11.08 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of or
exchange any Senior Note during a period beginning at the opening of business 15
days before the selection of Senior Notes to be redeemed under Section 11.04 and
ending at the close of business on the day of such mailing of the relevant
notice of redemption, or (ii) to register the transfer of or exchange any Senior
Note so selected for redemption in whole or in part, except the unredeemed
portion of any Senior Note being redeemed in part.

     SECTION 3.06. Book-entry Provisions for Global Senior Notes.

     (a) Each Global Senior Note initially shall (i) be registered in the name
of the Depositary for such Global Senior Notes or the nominee of such
Depositary, (ii) be delivered to the Trustee as custodian for such Depositary
and (iii) bear legends as set forth in Section 2.02.

                                       58

     Members of, or participants in, the Depositary ("AGENT MEMBERS") shall have
no rights under this Indenture with respect to any Global Senior Note, and the
Depositary may be treated by the Company, the Trustee and any agent of the
Company or the Trustee as the absolute owner of such Global Senior Note for all
purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
the Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depositary or impair, as between the Depositary and its Agent Members, the
operation of customary practices governing the exercise of the rights of a
beneficial owner of any Senior Note. The registered holder of a Global Senior
Note may grant proxies and otherwise authorize any person, including Agent
Members and persons that may hold interests through Agent Members, to take any
action which a Holder is entitled to take under this Indenture or the Senior
Notes.

     (b) Interests of beneficial owners in a Global Senior Note may be
transferred in accordance with the applicable rules and procedures of the
Depositary and the provisions of Section 3.07. The Senior Notes shall be issued
in global form only, and transfers of a Global Senior Note shall be limited to
transfers of such Global Senior Note in whole, but not in part, to the
Depositary, its successors or their respective nominees, except that U.S.
Physical Senior Notes or Offshore Physical Senior Notes shall be transferred to
all beneficial owners in exchange for their beneficial interests in the U.S.
Global Senior Note or the Offshore Global Senior Note, respectively, in the
following circumstances: (x) the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for the applicable Global Senior
Note or the Depositary ceases to be a "CLEARING AGENCY" registered under the
Exchange Act and a successor depositary is not appointed by the Company within
90 days or (y) an Event of Default has occurred and is continuing and Holders of
more than 25% in aggregate principal amount of the Senior Notes at the time
outstanding represented by the Global Senior Notes advise the Trustee through
the Depositary in writing that the continuation of a book-entry system through
the Depositary with respect to the Global Senior Notes is no longer required. In
connection with a transfer of an entire Global Senior Note to beneficial owners
pursuant to clause (ii) of this paragraph (b), the applicable Global Senior Note
shall be deemed to be surrendered to the Trustee for cancellation, and the
Company shall execute, and the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depositary in exchange for its beneficial
interest in the applicable Global Senior Note, an equal aggregate principal
amount at maturity of U.S. Physical Senior Notes (in the case of the U.S. Global
Senior Note) or Offshore Physical Senior Notes (in the case of the Offshore
Global Senior Note), as the case may be, of authorized denominations.

     (c) Any beneficial interest in one of the Global Senior Notes that is
transferred to a person who takes delivery in the form of an interest in the
other Global Senior Note will, upon transfer, cease to be an interest in such
Global Senior Note and become an interest in the other Global Senior Note and,
accordingly, will thereafter be subject to all transfer restrictions, if any,
and other procedures applicable to beneficial interests in such other Global
Senior Note for as long as it remains such an interest.

     (d) With respect to the Series A Senior Notes, any U.S. Physical Senior
Note delivered in exchange for an interest in the U.S. Global Senior Note
pursuant to

                                       59

paragraph (b) of this Section shall, unless such exchange is made on or after
the Resale Restriction Termination Date and except as otherwise provided in
Section 3.07, bear the Private Placement Legend.

     (e) With respect to the Series A Senior Notes, any Offshore Physical Senior
Note delivered in exchange for an interest in the Offshore Global Senior Note
pursuant to paragraph (b) of this Section shall, unless such exchange is made
after the Offshore Senior Note Restricted Period, and except as otherwise
provided in Section 3.07, bear the Private Placement Legend.

     SECTION 3.07. Transfer Provisions.

     (a) General. The provisions of this Section 3.07 shall apply to all
transfers involving any Physical Senior Note and any beneficial interest in any
Global Senior Note.

     (b) Certain Definitions. As used in this Section 3.07 only, "DELIVERY" of a

Co-Registrar by such transferee or transferor of the applicable certificate duly
completed; "HOLDING" includes both possession of a Physical Senior Note and
ownership of a beneficial interest in a Global Senior Note, as the context
requires; "TRANSFERRING" a Global Senior Note means transferring that portion of
the principal amount of the transferor's beneficial interest therein that the
transferor has notified the Co-Registrar that it has agreed to transfer; and
"TRANSFERRING" a Physical Senior Note means transferring that portion of the
principal amount thereof that the transferor has notified the Registrar or
Co-Registrar that it has agreed to transfer.

     As used in this Indenture, "REGULATION S CERTIFICATE" means a certificate

that, the proposed transfer is being made pursuant to an exemption from, or in a
transaction not subject to, the registration requirements of the Securities Act.

     (c) [Intentionally Omitted]

     (d) Deemed Delivery of a Rule 144A Certificate in Certain Circumstances. A

either declined such opportunity or has received such information (or, in the
case of a transfer of a Physical Senior Note, the transferee signs the
certification provided on the Physical Senior Note to that effect); or (B) the
transferor holds the U.S. Global Senior Note and is transferring to a transferee
that will take delivery in the form of the U.S. Global Senior Note.

     (e) Procedures and Requirements. Unless and until a Series A Senior Note is

registration statement pursuant to the Registration Rights Agreement, the
following provisions shall apply:

         (i) Transfers to QIBs. The following provisions shall apply with

               (A) If the Senior Note to be transferred is (1) a Physical Senior
         Note, the Registrar shall register the transfer, if such transfer is
         being made by a proposed transferor who delivers (or is deemed to have
         delivered) a Rule 144A Certificate or (2) an interest in any Global
         Senior Note, the transfer of such interest may be effected only through
         the book entry system maintained by the Depositary, if such transfer is
         being made by a proposed transferor who delivers(or is deemed to have
         delivered) a Rule 144A Certificate.

               (B) If the proposed transferee is an Agent Member, and the Senior
         Note to be transferred is a Physical Senior Note, upon receipt by the
         Registrar of the documents referred to in clause (i)(A) and
         instructions given in accordance with the Depositary's and the
         Registrar's procedures, the Registrar shall reflect on its books and
         records the date and an increase in the principal amount of the Global
         Senior Note in an amount equal to the principal amount of the Physical
         Senior Note to be transferred and the Trustee shall cancel the Physical
         Senior Note so transferred.

         (ii) Transfers of Interests in the Offshore Global Senior Note. The
     following provisions shall apply with respect to registration of any
     proposed transfer of interests in the Offshore Global Senior Note:

               (A) The Registrar shall register the transfer of any Offshore
         Global Senior Note bearing the Private Placement Legend (1) if the
         proposed transferee is a Non-U.S. Person and the proposed transferor
         has delivered to the Registrar a Regulation S Certificate or (2) if the
         proposed transferee is a QIB and the proposed transferor delivers (or
         is deemed to have delivered) a Rule 144A Certificate.

                                       61

               (B) If the proposed transferee of any Offshore Global Senior Note
         bearing the Private Placement Legend is an Agent Member, upon receipt
         by the Registrar of the documents referred to in clause (ii)(A)(2)
         above and instructions given in accordance with the Depositary's and
         the Registrar's procedures, the Registrar shall reflect on its books
         and records the date and an increase in the principal amount of the
         U.S. Global Senior Note, in an amount equal to the principal amount of
         the Offshore Global Senior Note to be transferred, and the Trustee
         shall decrease the amount of the Offshore Global Senior Note.

               (C) Prior to the expiration of the Offshore Senior Note
         Restricted Period, the Registrar shall refuse to register the transfer
         of any Offshore Senior Note to any U.S. Person; and

               (D) After the expiration of the Offshore Senior Note Restricted
         Period, the Registrar shall register the transfer of any such Senior
         Note without requiring any additional certification.

         (iii) Transfers to Non-U.S. Persons at Any Time. The following
     provisions shall apply with respect to any transfer of a Senior Note to a
     Non-U.S. Person:

               (A) Prior to the completion of the Offshore Senior Note
         Restricted Period, the Registrar shall register any proposed transfer
         of a Senior Note to a Non-U.S. Person upon receipt of a Regulation S
         Certificate from the proposed transferor.

               (B) After the completion of the Offshore Senior Note Restricted
         Period, the Registrar shall register any proposed transfer to any
         Non-U.S. Person if the Senior Note to be transferred is a U.S. Physical
         Senior Note or an interest in a U.S. Global Senior Note, upon receipt
         of a Regulation S Certificate from the proposed transferor.

               (C) If the proposed transferor is an Agent Member holding a
         beneficial interest in the U.S. Global Senior Note, upon receipt by the
         Registrar of (1) the documents, if any, required by paragraph (iii)(B)
         and (2) instructions in accordance with the Depositary's and the
         Registrar's procedures, the Registrar shall reflect on its books and
         records the date and a decrease in the principal amount of the U.S.
         Global Senior Note in an amount equal to the principal amount of the
         beneficial interest in the U.S. Global Senior Note to be transferred,
         and if the proposed transferee is an Agent Member, upon receipt by the
         Registrar of instructions given in accordance with the Depositary's and
         the Registrar's procedures, the Registrar shall reflect on its books
         and records the date and an increase in the principal amount of the
         Offshore Global Senior Note in an amount equal to the principal amount
         of the U.S. Physical Senior Note or the U.S. Global Senior Note, as the
         case may be, to be transferred, and the Trustee

                                       62

         shall cancel the Physical Senior Note, if any, so transferred or
         decrease the amount of the U.S. Global Senior Note, as the case may be.

     (f) Execution, Authentication and Delivery of Physical Senior Notes. In any
case in which the Co-Registrar is required to deliver a Physical Senior Note to
a transferee, the Company shall execute, and the Trustee shall authenticate and
deliver, such Physical Senior Note.

     (g) Certain Additional Terms Applicable to Physical Senior Notes. (i) Any
transferee entitled to receive a Physical Senior Note may request that the
principal amount thereof be evidenced by one or more Physical Senior Notes in
any authorized denomination or denominations and the Registrar or Co-Registrar
shall comply with such request if all other transfer restrictions are satisfied.

         (ii) In the event that a transferor transfers less than the entire
     principal amount of a Physical Senior Note surrendered for transfer,
     following the transfer the Registrar or Co-Registrar shall deliver to the
     transferor a new Physical Senior Note of the same type in principal amount
     equal to the untransferred portion of the surrendered Physical Senior Note.

     (h) Transfers Not Covered by Section 3.07(e). The Co-Registrar shall effect
and record, upon receipt of a written request from the Company so to do, a
transfer not otherwise permitted by Section 3.07(e), such recording to be done
in accordance with the otherwise applicable provisions of Section 3.07(e), upon
the furnishing by the proposed transferor or transferee of a Non-Registration
Opinion and Supporting Evidence.

     (i) General. Upon the transfer, exchange or replacement of Senior Notes not
bearing the Private Placement Legend, the Registrar shall deliver Senior Notes
that do not bear the Private Placement Legend. Except as otherwise provided
hereunder, upon the transfer, exchange or replacement of Senior Notes bearing
the Private Placement Legend, the Registrar shall deliver only Senior Notes that
bear the Private Placement Legend unless there is delivered to the Registrar an
Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the
effect that neither such legend nor the related restrictions on transfer are
required in order to maintain compliance with the provisions of the Securities
Act. By its acceptance of any Senior Note bearing the Private Placement Legend,
each Holder of such Senior Note acknowledges the restrictions on transfer of
such Senior Note set forth in this Indenture and in the Private Placement Legend
and agrees that it will transfer such Senior Note only as provided in the
Indenture. Neither the Registrar nor the Co-Registrar shall register a transfer
of any Senior Note unless such transfer complies with the restrictions with
respect thereto set forth in this Indenture. Neither the Registrar nor the
Co-Registrar shall be required to determine (but may rely upon a determination
made by the Company) the sufficiency of any such certifications, legal opinions
or other information.

     The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Senior Note (including

                                       63

any transfers between or among Agent Members or beneficial owners of interests
in any Global Senior Note) other than to require delivery of such certificates
and other documentation or evidence as are expressly required by, and to do so
if and when expressly required by the terms of, this Indenture, and to examine
the same to determine substantial compliance as to form with the express
requirements hereof.

       Re:  Indenture (the "INDENTURE") dated as of March 31, 1998 between
            Mastellone Hermanos S.A. (the "COMPANY") and the Trustee

Ladies and Gentlemen:

     This Certificate relates to our proposed transfer of $___________ principal
amount of Senior Notes issued under the Indenture. Terms are used in this
Certificate as defined in Regulation S under the Securities Act of 1933, as
amended (the "SECURITIES ACT"). We hereby certify as follows:

     1. The offer of the Senior Notes was not made to a person in the United
States (unless such person or the account held by it for which it is acting is
excluded from the definition of "U.S. PERSON" pursuant to Rule 902(o) of
Regulation S under the circumstances described in Rule 902(i)(3) of Regulation
S) or specifically targeted at an identifiable group of U.S. citizens abroad.

     2. Either (a) at the time the buy order was originated, the buyer was
outside the United States or we and any person acting on our behalf reasonably
believed that the buyer was outside the United States or (b) the transaction was
executed in, on or through the facilities of a designated offshore securities
market, and neither we nor any person acting on our behalf knows that the
transaction was pre-arranged with a buyer in the United States.

     3. Neither we, any of our affiliates, nor any person acting on our or their
behalf has made any directed selling efforts in the United States.

     4. The proposed transfer of Senior Notes is not part of a plan or scheme to
evade the registration requirements of the Securities Act.

                                       64

     5. If we are a dealer or a person receiving a selling concession or other
fee or remuneration in respect of the Senior Notes, and the proposed transfer
takes place before completion of the Offshore Senior Note Restricted Period
referred to in the Indenture, or we are an officer or director of the Company or
a distributor, we certify that the proposed transfer is being made in accordance
with the provisions of Rule 904(c) of Regulation S.

     Re:  Indenture (the "INDENTURE") dated as of March 31, 1998 between
          Mastellone Hermanos S.A. (the "COMPANY") and the Trustee

Ladies and Gentlemen:

     This Certificate relates to our proposed purchase of $___________ principal
amount of Senior Notes issued under the Indenture. We and, if applicable, each
account for which we are acting, are "QUALIFIED INSTITUTIONAL BUYERS" within the
meaning of Rule 144A ("RULE 144A") under the Securities Act of 1933, as amended
(the "SECURITIES ACT"). We are aware that the transfer of Senior Notes to us is
being made in reliance on the exemption from the provisions of Section 5 of the
Securities Act provided by Rule 144A. Prior to the date of this Certificate we
have been given the opportunity to obtain

                                       65

from the Company the information referred to in Rule 144A(d)(4), and have either
declined such opportunity or have received such information.

     You and the Company are entitled to conclusively rely upon this Certificate
and are irrevocably authorized to produce this Certificate or a copy hereof to
any interested party in any administrative or legal proceeding or official
inquiry with respect to the matters covered hereby.

                                        Very truly yours,

                                        [NAME OF PURCHASER]

     SECTION 3.11. Mutilated, Destroyed, Lost and Stolen Senior Notes.

     If (a) any mutilated Senior Note is surrendered to the Trustee, or (b) the
Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Senior Note, and there is delivered to the
Company and the Trustee such security or indemnity as may be required by them to
save each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Senior Note has been acquired by a bona fide purchaser, the
Company shall execute and upon Company Order the Trustee shall authenticate and
deliver, in exchange for any such mutilated Senior Note or in lieu of any such
destroyed, lost or stolen Senior Note, a new Senior Note of like tenor and
principal amount, bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Senior Note has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Senior Note, pay such Senior Note.

     Upon the issuance of any new Senior Note under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

     Every new Senior Note issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Senior Note shall be at any time enforceable by
anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Senior Notes duly issued hereunder.

                                       66

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Senior Notes.

     SECTION 3.12. Payment of Interest; Interest Rights Preserved.

     Interest on any Senior Note (and any Additional Amounts payable in respect
thereof and any Liquidated Damages) which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name such Senior Note (or one or more Predecessor Senior Notes) is
registered at the close of business on the Regular Record Date for such interest
at the offices or agencies of the Company in The City of New York and the City
of Buenos Aires maintained for such purposes (which initially will be the
Principal Paying Agent and the Registrar, respectively) pursuant to Section
10.02.

     The Company shall provide to the Principal Paying Agent in same day funds
on or before 12 Noon (New York City time) one Business Day prior to each date on
which a payment of principal of or any interest on the Senior Notes shall become
due, as set forth in the text of the Senior Notes, such amount in US Dollars as
is necessary to make such payment, and the Company hereby authorizes and directs
the Principal Paying Agent from funds so provided to it to make or cause to be
made payment of the principal of and any interest, as the case may be, on the
Senior Notes as set forth herein and in the text of said Senior Notes; provided
that payment of interest on the Senior Notes may be made directly by the
Company, by US Dollar check drawn on a bank in The City of New York mailed to
the Person entitled thereto as provided in the text of the Senior Notes.
Payments of any interest on the Senior Notes may be made, in the case of a
registered holder of at least US$1,000,000 aggregate principal amount of Senior
Notes, by wire transfer to a US Dollar account maintained by the payee with a
bank in the United States or in Argentina; provided that such Holder elects
payment by wire transfer by giving written notice to the Principal Paying Agent
to such effect designating such account with appropriate wire transfer
instructions no later than the Regular Record Date immediately preceding such
Interest Payment Date, or such other date at the discretion of the Principal
Paying Agent. Unless such designation is revoked, any such designation made by
such Holder with respect to such Senior Notes shall remain in effect with
respect to any future payments of interest with respect to such Senior Notes
payable to such Holder. The Company shall pay any administrative costs imposed
by banks in connection with making payments by wire transfer. The Principal
Paying Agent shall arrange directly with any other Paying Agent who may have
been appointed by the Company pursuant to the provisions of this Indenture for
the payment from funds so paid by the Company to the Principal Paying Agent of
the principal of and any interest on the Senior Notes as set forth herein and in
the text of said Senior Notes. Notwithstanding the foregoing, the Company may
upon prompt written notice to the Principal Paying Agent and the Trustee provide
directly to another Paying Agent funds for the payment of the principal or any
interest on any of the Senior Notes pursuant to an agreement with respect to
such funds containing substantially the same terms and conditions set forth in
this Section 3.12; and the Principal Paying Agent shall have no responsibility
with respect to any funds so provided by the Company to any such other Paying
Agent.

                                       67

     Any interest on any Senior Note (and any Additional Amounts payable in
respect thereof and any Liquidated Damages) which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date shall
forthwith cease to be payable to the Holder on the Regular Record Date by virtue
of having been such Holder, and such defaulted interest (and any Additional
Amounts payable in respect thereof and any Liquidated Damages) and (to the
extent lawful) interest on such defaulted interest at the rate borne by the
Senior Notes (such defaulted interest and interest thereon herein collectively
called "DEFAULTED INTEREST") may be paid by the Company, at its election in each
case, as provided in clause (a) or (b) below:

     (a) The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Senior Notes (or their respective Predecessor Senior
Notes) are registered at the close of business on a Special Record Date for the
payment of such Defaulted Interest, which shall be fixed in the following
manner. The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Senior Note and the date of the
proposed payment, and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount proposed to be paid in
respect of such Defaulted Interest or shall make arrangements satisfactory to
the Trustee for such deposit prior to the date of the proposed payment, such
money when deposited to be held in trust for the benefit of the Persons entitled
to such Defaulted Interest as in this clause provided. Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest which
shall be not more than 15 days and not less than 10 days prior to the date of
the proposed payment and not less than 10 days after the receipt by the Trustee
of the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date, and in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be given in the manner provided for in
Section 1.06, not less than 10 days prior to such Special Record Date. Notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor having been so given, such Defaulted Interest shall be paid to the
Persons in whose names the Senior Notes (or their respective Predecessor Senior
Notes) are registered at the close of business on such Special Record Date and
shall no longer be payable pursuant to the following clause (2).

     (b) The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Senior Notes may be listed, and upon such notice as may be required
by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be deemed
practicable by the Trustee.

     Subject to the foregoing provisions of this Section, each Senior Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Senior Note shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Senior Note.

                                       68

     SECTION 3.13. Persons Deemed Owners.

     Prior to the due presentment of a Senior Note for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Note is registered as the owner of such Senior
Note for the purpose of receiving payment of principal of (and premium, if any)
and (subject to Sections 3.05 and 3.11) interest on such Senior Note and for all
other purposes whatsoever, whether or not such Senior Note be overdue, and none
of the Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

     SECTION 3.14. Cancellation.

     All Senior Notes surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
shall be promptly canceled by it and delivered to the Trustee. The Company may
at any time deliver to the Trustee for cancellation any Senior Notes previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and may deliver to the Trustee (or to any other Person for
delivery to the Trustee) for cancellation any Senior Notes previously
authenticated hereunder which the Company has not issued and sold, and all
Senior Notes so delivered shall be promptly canceled by the Trustee. If the
Company shall so acquire any of the Senior Notes, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Senior Notes unless and until the same are surrendered to
the Trustee for cancellation. No Senior Notes shall be authenticated in lieu of
or in exchange for any Senior Notes canceled as provided in this Section, except
as expressly permitted by this Indenture. All canceled Senior Notes held by the
Trustee shall be disposed of by the Trustee in accordance with its customary
procedures and certification of their disposal delivered to the Company unless
by Company Order the Company shall direct that canceled Senior Notes be returned
to it.

     SECTION 3.15. Computation of Interest.

     Interest on the Senior Notes shall be computed on the basis of a 360-day
year of twelve 30-day months.

     SECTION 3.16. Cusip and CINS Numbers.

     The Company in issuing the Senior Notes may use "CUSIP" and "CINS" numbers
(if then generally in use), and, if so, the Trustee shall use "CUSIP" or "CINS"
numbers in notices of redemption as a convenience to Holders; provided that any
such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Senior Notes or as contained in any notice
of a redemption and that reliance may be placed only on the other identification
numbers printed on the Senior Notes, and any such redemption shall not be
affected by any defect in or omission of such numbers. The Company will promptly
notify the Trustee of any change in the "CUSIP" or "CINS" numbers.

                                       69

paragraph of this Section 4.01) and the Trustee, at the expense of the Company,

     Notes for whose payment money has theretofore been deposited in trust with
     the Trustee or any Paying Agent or segregated and held in trust by the
     Company and thereafter repaid to the Company or discharged from such trust,
     as provided in Section 10.03) have been delivered to the Trustee for
     cancellation; or

         (ii) all Senior Notes not theretofore delivered to the Trustee for
     cancellation

               (A) have become due and payable, or

               (B) will become due and payable at their Stated Maturity within
         one year, or

               (C) are to be called for redemption within one year under
         arrangements satisfactory to the Trustee for the giving of notice of

         Company, and the Company or any Subsidiary Guarantor has irrevocably
         deposited or caused to be deposited with the Trustee as trust funds in
         trust for such purpose an amount sufficient to pay and discharge the
         entire Indebtedness on such Senior Notes not theretofore delivered to
         the Trustee for cancellation, for principal of, premium, if any, and
         interest on the Senior Notes to the date of such deposit (in the case
         of Senior Notes which have become due and payable) or to the Stated
         Maturity or Redemption Date, as the case may be;

     (b) the Company or any Subsidiary Guarantor has paid or caused to be paid
all sums payable hereunder by the Company and any Subsidiary Guarantor; and

     (c) the Company has delivered to the Trustee an Officers' Certificate and

provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

                                       70

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Sections 6.06 and 10.09 and, if
money shall have been deposited with the Trustee pursuant to subclause (B) of
clause (1) of this Section, the obligations of the Trustee under Section 4.02
and the last paragraph of Section 10.03 shall survive.

     SECTION 4.02. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 10.03, all money
deposited with the Trustee pursuant to Section 4.01 shall be held in trust and
applied by it, in accordance with the provisions of the Senior Notes and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the
Trustee; but such money need not be segregated from other funds except to the
extent required by law.

                                    REMEDIES

     SECTION 5.02. Acceleration of Maturity; Recission and Annulment.

     If an Event of Default (other than an Event of Default specified in clause
(i) or (j) of Section 5.01) shall occur and be continuing, then and in every
such case the Trustee, by written notice to the Company, or the Holders of not
less than 25% in principal amount of the Senior Notes then Outstanding may, and
the Trustee, upon the written request of such Holders, shall declare the
principal of, premium, if any, and accrued interest, and any Liquidated Damages
and Additional Amounts on all of the Outstanding Senior Notes to be due and
payable immediately, and upon any such declaration all such amounts payable in
respect of the Senior Notes shall become immediately due and payable. If an
Event of Default specified in clause (i) or (j) of Section 5.01 shall occur and
be continuing with respect to the Company, then the principal amount of,
premium, if any, and accrued interest, and any Liquidated Damages and Additional
Amounts, on all the Senior Notes shall ipso facto become and be immediately due
and payable without any declaration or other act on the part of the Trustee or
any Holder.

     At any time after a declaration of acceleration under this Indenture has
been made, but before a judgment or decree for payment of the money due has been
obtained by the Trustee or any Holder as hereinafter provided in this Article,
the Holders of a majority in aggregate principal amount of the Senior Notes then
Outstanding, by written notice to the Company and the Trustee, may rescind such
declaration and its consequences if

     (a) the Company has paid or deposited with the Trustee a sum sufficient to
pay,

         (i) all overdue interest on all Outstanding Senior Notes, including any
     Liquidated Damages and Additional Amounts,

         (ii) all unpaid principal of, or Additional Amounts or Liquidated
     Damages, if any (and premium, if any,) on any Outstanding Senior Notes that
     has become due otherwise than by such declaration of acceleration, and
     interest thereon at the rate borne by the Senior Notes,

         (iii) to the extent that payment of such interest is lawful, interest
     upon overdue interest at the rate borne by the Senior Notes, and

                                       73

         (iv) all sums paid or advanced by the Trustee hereunder and the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel; and

     (b) all Events of Default, other than the non-payment of amounts of
principal of, or Additional Amounts, if any (or premium, if any, on), or
interest on the Senior Notes or Liquidated Damages, if any, which have become
due solely by such declaration of acceleration, have been cured or waived as
provided in Section 5.13.

     No such rescission shall affect any subsequent default or impair any right
consequent thereon.

     The foregoing provisions shall be without prejudice to the rights of each
individual Holder to initiate a summary action ("ACCION EJECUTIVA") against the
Company for the payment of any principal, interest, Liquidated Damages and/or
Additional Amounts past due on any Senior Note, as the case may be. The right of
any individual Holder to initiate such action against the Company shall comply
with Article 29 of the Argentine Negotiable Obligations Law.

     SECTION 5.03. Collection of Indebtedness and Suits for Enforcement by
Trustee.

     The Company covenants that if

     (a) default is made in the payment of any installment of interest, or on
any Liquidated Damages, on any Senior Note when such payment becomes due and
payable and such default continues for a period of 30 days, or

     (b) default is made in the payment of the principal of, or Additional
Amounts, if any (or premium, if any), on, any Senior Note at the Maturity
thereof, the Company will, upon demand of the Trustee, promptly pay to the
Trustee for the benefit of the Holders of such Senior Notes, the whole amount
then due and payable on such Senior Notes for principal (and premium, if any)
and interest and Additional Amounts and Liquidated Damages, if any, and interest
on any overdue principal (and premium, if any) and, to the extent that payment
of such interest shall be legally enforceable, upon any overdue installment of
interest and Additional Amounts and Liquidated Damages, if any, at the rate
borne by the Senior Notes, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

     Any Holder may institute proceedings directly against the Company for the
payment of past due principal, interest, Liquidated Damages or Additional
Amounts, if any, but from the date such proceedings are instituted, the Holder
of such Senior Notes, shall cease to have any rights under the trust created by
these presents, whether in relation to trust moneys (including moneys recovered
by the Trustee prior to the institution of such proceedings) or otherwise. The
Trustee shall be entitled to assume (and it is the

                                       74

intention of the parties that it will assume) that no such proceedings have been
instituted, unless it has express notice to the contrary.

     No Senior Note which has been the subject of such proceedings may be
presented to the Trustee, a Paying Agent or Registrar and Co-Registrar for
payment or replacement but in such circumstances the Company shall make separate
arrangements for payment directly to the Holder of each such Senior Note. If any
Holder, having instituted proceedings directly against the Company, subsequently
disposes of the Senior Note forming the subject matter of such proceedings, the
cessation of the rights under the trust created by these presents occurring upon
the institution of such proceedings, shall inure in relation to the purchaser of
such Senior Note. Upon notification by the Company of any such proceedings, the
Trustee shall give notice to the Paying Agents and the Registrar and
Co-Registrar of the serial numbers of those Senior Notes forming the subject
matter of such proceedings and the Paying Agents and Registrar and Co-Registrar
shall make such serial numbers available to any Holder or potential Holder upon
its request.

     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the Senior Notes and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Senior Notes, wherever
situated.

     If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

     SECTION 5.04. Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the Senior
Notes or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Senior
Notes shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal, premium, if any, or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

     (a) to file and prove a claim for the whole amount of principal (and
premium, if any) and interest owing and unpaid in respect of the Senior Notes
and to file such other papers or documents as may be necessary or advisable in
order to have the claims of the

                                       75

Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and of the
Holders allowed in such judicial proceeding, and

     (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.06.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Senior
Notes or the rights of any Holder thereof, or to authorize the Trustee to vote
in respect of the claim of any Holder in any such proceeding.

     SECTION 5.05. Trustee May Enforce Claims Without Possession of Senior
Notes. All rights of action and claims under this Indenture or the Senior Notes
may be prosecuted and enforced by the Trustee without the possession of any of
the Senior Notes or the production thereof in any proceeding relating thereto,
and any such proceeding instituted by the Trustee shall be brought in its own
name and as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Senior Notes in respect of which such
judgment has been recovered.

     SECTION 5.06. Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of the Senior Notes and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 6.06;

     SECOND: To the payment of the amounts then due and unpaid for principal of
(and premium, if any) and interest and Additional Amounts and Liquidated
Damages, if any, on the Senior Notes in respect of which or for the benefit of
which such money has been collected, ratably, without preference or priority of
any kind, according to the amounts due and payable on such Senior Notes for
principal (and premium, if any) and interest and Additional Amounts and
Liquidated Damages, if any, respectively; and

     THIRD: The balance, if any, to the Person or Persons entitled thereto.

                                       76

     SECTION 5.07. Limitation on Suits.

     Except as provided in the last paragraph of Section 5.02, no Holder of any
Senior Notes shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless

     (a) such Holder has previously given written notice to the Trustee of a
continuing Event of Default;

     (b) the Holders of not less than 25% in principal amount of the Outstanding
Senior Notes shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee
hereunder;

     (c) such Holder or Holders have offered to the Trustee reasonable indemnity
against the costs, expenses and liabilities to be incurred in compliance with
such request;

     (d) the Trustee for 60 days after its receipt of such notice, request and
offer of indemnity has failed to institute any such proceeding; and

     (e) no direction inconsistent with such written request has been given to
the Trustee during such 60-day period by the Holders of a majority or more in
principal amount of the Outstanding Senior Notes;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

     SECTION 5.08. Unconditional Right of Holders to Receive Principal, Premium,
Interest, Liquidated Damages and Additional Amounts.

     Notwithstanding any other provision in this Indenture, the Holder of any
Senior Note shall have the right, which is absolute and unconditional, to
receive payment, as provided herein (including, if applicable, Article Twelve)
and in such Senior Note of the principal of (and premium, if any) and (subject
to Section 3.11) interest and Additional Amounts and Liquidated Damages, if any,
on such Senior Note on the respective Stated Maturities expressed in such Senior
Note (or, in the case of redemption, on the Redemption Date) and to institute
suit for the enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder.

     SECTION 5.09. Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and

                                       77

in every such case, subject to any determination in such proceeding, the
Company, the Trustee and the Holders shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

     SECTION 5.10. Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Senior Notes in the last paragraph of
Section 3.06, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

     SECTION 5.11. Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Senior Note to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

     SECTION 5.12. Control by Holders.

     Subject to the provisions of Section 6.02(5), the Holders of not less than
a majority in aggregate principal amount of the Outstanding Senior Notes shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee, provided that

     (a) such direction shall not be in conflict with any rule of law or with
this Indenture,

     (b) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and

     (c) the Trustee need not take any action which might involve it in personal
liability or be unjustly prejudicial to the Holders not consenting.

     SECTION 5.13. Waiver of Past Defaults.

     The Holders of not less than a majority in aggregate principal amount of
the Outstanding Senior Notes may on behalf of the Holders of all the Senior
Notes, waive any past default hereunder or under this Indenture and its
consequences, except a default

                                       78

     (a) in respect of the payment of the principal of (or premium, if any) or
interest or any Additional Amount or Liquidated Damages on any Senior Note, or

     (b) in respect of a covenant or provision hereof which under Article Nine
cannot be modified or amended without the consent of the Holder of each
Outstanding Senior Note.

     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon.

     SECTION 5.14. Waiver of Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

     SECTION 5.15. Currency Indemnity.

     All amounts payable under the Indenture are payable in US Dollars. Any
amount received or recovered in currency other than US Dollars (whether as a
result of, or of the enforcement of, a judgment or order of a court of any
jurisdiction, in the winding up or dissolution of the Company or otherwise) by
any Holder in respect of any sum expressed to be due to it from the Company
shall only constitute discharge of the Company to the extent of the US Dollar
amount which the recipient is able to purchase with the amount so received or
recovered in that other currency on the date of that receipt or recovery (or, if
it is not practicable to make that purchase on that date, on the first date on
which it is practicable to do so). If that US Dollar amount is less than the US
Dollar amount expressed to be due to the recipient under any Senior Note or
Subsidiary Guarantee, the Company shall indemnify such recipient against any
loss sustained by it as a result. In any event, the Company shall indemnify the
recipient against the cost of making any such purchase. For the purposes of this
paragraph, it will be sufficient for the Holder to certify in a reasonably
satisfactory manner (indicating the sources of information used) that it would
have suffered a loss had an actual purchase of US Dollars been made with the
amount so received in that other currency on the date of receipt or recovery
(or, if a purchase of US Dollars on such date had not been practicable, on the
first date on which it would have been practicable, it being required that the
need for a change of date be certified in the manner mentioned above). These
indemnities constitute a separate and independent obligation from the Company's
other obligations, shall give rise to a separate and independent cause of
action, shall apply irrespective of any waiver granted by a Holder and shall
continue in full force and effect despite any other judgment, order,

                                       79

claim or proof for a liquidated amount in respect of any sum due under any
Senior Note or Subsidiary Guarantee or any other judgment or order.

                                    ARTICLE 6
                                   The Trustee

     SECTION 6.01. Notice of Default.

     (a) Within 5 days after obtaining actual knowledge of the occurrence of any
Default hereunder, the Trustee shall transmit to the Holders in the manner and
to the extent provided in TIA Section 313(c), notice of any such Default
hereunder actually known to a Responsible Officer of the Trustee, unless such
Default shall have been cured or waived; provided that, except in the case of a
Default in the payment of the principal of (or premium, if any) or interest on
any Senior Note, the Trustee shall be protected in withholding such notice if
and so long as the board of directors, the executive committee or a trust
committee of directors and/or Responsible Officers of the Trustee in good faith
determines that the withholding of such notice is in the interest of the
Holders; and provided further that, in the case of any Default of the character
specified in Section 5.01 (iv), no such notice to Holders shall be given until
at least 30 days after the occurrence thereof.

     (b) The Trustee shall not be deemed to have notice of any Default unless a
Responsible Officer of the Trustee has actual knowledge thereof or unless
written notice of any event which is in fact such a default is received by the
Trustee at the Corporate Trust Office of the Trustee, and such notice references
the Senior Notes and this Indenture.

     SECTION 6.02. Certain Rights of Trustee.

     Subject to the provisions of TIA Sections 315(a) through 315(d) (determined
as if the TIA were applicable to this Indenture at all times):

     (a) the Trustee shall conclusively rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,

     (c) whenever in the administration of this Indenture the Trustee shall deem
it desirable that a matter be proved or established prior to taking, suffering

specifically prescribed)

                                       80

may, in the absence of bad faith on its part, conclusively rely upon an
Officers' Certificate;

     (d) the Trustee may consult with counsel of its selection and the written
advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

     (e) the Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of
the Holders pursuant to this Indenture, unless such Holders shall have offered
to the Trustee reasonable security or indemnity against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or
direction;

     (f) the Trustee shall not be bound to make any investigation into the facts
or matters stated in any resolution, certificate, statement, instrument,

Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;

     (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder; and

     (h) the Trustee shall not be liable for any action taken, suffered or
omitted by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture.

     The Trustee shall have, but it will not be required to exercise, the powers
contemplated by Article 344, 345 (paragraph 1 and 2) and 351 of Argentine Law
No. 19,550, as amended, and Article 13 of the Argentine Negotiable Obligations
Law.

     No provision of this Indenture shall require the Trustee to expend or risk
its own funds or otherwise incur any financial liability in the performance of
any of its duties hereunder or in the exercise of any of its rights or powers
hereunder if it shall have reasonable grounds for believing that repayment of
such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

     SECTION 6.03. Trustee Not Responsible for Recitals or Issuance of Senior
Notes.

     The Trustee makes no representations as to the validity or sufficiency of
this Indenture, any offering materials or of the Senior Notes, except that the
Trustee represents that it is duly authorized to execute and deliver this
Indenture, authenticate the

                                       81

Senior Notes and perform its obligations hereunder and that the statements made
by it in any Statement of Eligibility on Form T-1 supplied to the Company are
true and accurate, subject to any qualifications set forth therein. The Trustee
shall not be accountable for the use or application by the Company of Senior
Notes or the proceeds thereof.

     SECTION 6.04. May Hold Senior Notes.

     The Trustee, any Paying Agent, any Registrar, Co-Registrar or any other
agent of the Company or of the Trustee, in its individual or any other capacity,
may become the owner or pledgee of Senior Notes and, subject to TIA Sections
310(b) and 311, may otherwise deal with the Company with the same rights it
would have if it were not Trustee, Paying Agent, Registrar, Co-Registrar or such
other agent.

     SECTION 6.05. Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

     SECTION 6.06. Compensation and Reimbursement.

     The Company agrees:

     (a) to pay to the Trustee such compensation as shall be agreed upon in
writing with the Company from time to time for all services rendered by it
hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust);

     (b) to reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any provision of this Indenture (including the reasonable compensation and the
expenses and disbursements of its agents and counsel), except any such expense,
disbursement or advance as may be attributable to its negligence or bad faith;
and

     (c) to indemnify the Trustee, its agents and other Persons employed by the
Trustee in accordance with the terms of this Indenture for, and to hold them
harmless against, any and all losses, damages, liabilities, judgments, claims,
causes of action, costs and expenses (including fees and disbursements of legal
counsel) incurred directly or indirectly, without negligence or bad faith on
their part, arising out of or in connection with the acceptance or
administration of this trust or the exercise of their rights or the performance
of their duties under this Indenture, including the costs and expenses of

premises.

     The obligations of the Company under this Section to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee, its agents and other
Persons employed by the Trustee in accordance with the terms of this Indenture
shall constitute additional indebtedness

                                       82

hereunder and shall survive the satisfaction and discharge or other termination
of this Indenture, the resignation or removal of the Trustee and payment of the
Senior Notes. As security for the performance of such obligations of the
Company, the Trustee shall have a lien prior to the Senior Notes upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (and premium, if any) or interest on
particular Senior Notes.

     When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.01(x) or (xi), the expenses (including
the reasonable charges and expenses of its counsel) of and the compensation for
such services are intended to constitute expenses of administration under any
applicable Federal or State bankruptcy, insolvency or other similar law.

     The provisions of this Section shall survive the termination of this
Indenture, payment of the Senior Notes and/or the removal or resignation of the
Trustee.

     The rights, benefits, protections, priveleges and immunities provided to
the Trustee hereunder including, without limitation, the right to
indemnification, shall extend to, and shall be enforceable by, the Co-Registrar,
Principal Paying Agent, Registrar and Paying Agent.

Law Section 13 and shall have a combined capital and surplus of at least
US$50,000,000. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of Federal, State, territorial
or District of Columbia supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time the Trustee shall cease
to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.

     SECTION 6.08. Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.09.

     (b) The Trustee may resign at any time by giving written notice thereof to
the Company. If the instrument of acceptance by a successor Trustee required by
Section 6.09 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                                       83

     (c) The Trustee may be removed at any time by Act of the Holders of not
less than a majority in principal amount of the Outstanding Senior Notes,
delivered to the Trustee and to the Company.

     (d) If at any time:

         (i) the Trustee shall fail to comply with the provisions of TIA Section
     310(b) after written request therefor by the Company or by any Holder who
     has been a bona fide Holder of a Senior Note for at least six months, or

         (ii) the Trustee shall cease to be eligible under Section 6.07 and
     shall fail to resign after written request therefor by the Company or by
     any Holder who has been a bona fide Holder of a Senior Note for at least
     six months, or

         (iii) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company, by a Board Resolution, may remove the
Trustee, or (ii) subject to TIA Section 315(e), any Holder who has been a bona
fide Holder of a Senior Note for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor Trustee.

     If an instrument of acceptance by a successor Trustee shall not have been
delivered to the Trustee within 30 days after the giving of such notice of
removal, the Trustee being removed may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Senior Notes.

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company,
by a Board Resolution, shall promptly appoint a successor Trustee. If, within
one year after such resignation, removal or incapability, or the occurrence of
such vacancy, a successor Trustee shall be appointed by Act of the Holders of a
majority in principal amount of the Outstanding Senior Notes delivered to the
Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment, become the successor Trustee
and supersede the successor Trustee appointed by the Company. If no successor
Trustee shall have been so appointed by the Company or the Holders and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona
fide Holder of a Senior Note for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the appointment of a successor Trustee.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee to the Holders of Senior
Notes in the manner provided for in Section 1.06. Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.

                                       84

     SECTION 6.09. Acceptance of Appointment by Successor.

     Every successor Trustee appointed hereunder shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder. Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts.

     No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified under TIA Section
310(b) and eligible under Section 6.07.

     SECTION 6.10. Merger, Conversion, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Senior Notes shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Senior Notes so authenticated with the same
effect as if such successor Trustee had itself authenticated such Senior Notes.
In case at that time any of the Senior Notes shall not have been authenticated,
any successor Trustee may authenticate such Senior Notes either in the name of
any predecessor hereunder or in the name of the successor Trustee. In all such
cases such certificates shall have the full force and effect which this
Indenture provides that the certificate of authentication of the Trustee shall
have; provided, however, that the right to adopt the certificate of
authentication of any predecessor Trustee or to authenticate Senior Notes in the
name of any predecessor Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

     SECTION 6.11. Preferential Collection of Claims Against Company.

     The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship listed in Section 311(b) of that Act. If the
present or any future Trustee shall resign or be removed, it shall be subject to
Section 311(a) of the Trust Indenture Act to the extent provided therein.

                                       85

     SECTION 6.12. Other Capacities.

     Except as otherwise specifically provided herein, (i) all references in
this Indenture to the Trustee shall be deemed to refer to the Trustee in its
capacity as Trustee and in its capacities as Co-Registrar and Principal Paying
Agent and (ii) every provision of this Indenture relating to the conduct of, or
affecting the liability or offering protection, immunity or indemnity to, the
Trustee shall be deemed to apply with the same force and effect to the Trustee
acting in its capacities as Co-Registrar and Principal Paying Agent.

     SECTION 6.13. Appointment of Co-Trustee or Separate Trustee. (a)
Notwithstanding any other provisions of this Indenture, at any time, for the
purpose of meeting any legal requirement of any jurisdiction in which
enforcement may be necessary by the Trustee with respect to the Senior Notes or
for any other reason, the Trustee shall have the power and may execute and
deliver all instruments to appoint one or more Persons to act as a co-trustee or
co-trustees, or separate trustee or separate trustees and to vest in such Person
or Persons, in such capacity and for the benefit of the holders, and subject to
the other provisions of this Indenture, such powers, duties, obligations and

assets of the Company

                                       89

or any Subsidiary Guarantor in accordance with Section 8.01 in which the Company
or the Subsidiary Guarantor, as the case may be, is not the continuing obligor
under this Indenture or the Subsidiary Guarantee, the Surviving Entity or
Surviving Guarantor Entity, as the case may be, shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under
this Indenture or the Subsidiary Guarantor under the Subsidiary Guarantee, as
the case may be, with the same effect as if such successor had been named as the
Company or the Subsidiary Guarantor therein; and any Senior Note authenticated
or delivered prior to such consolidation, merger, sale, assignment, conveyance,

released from those obligations; provided that, in the case of a transfer by
lease, the predecessor shall not be released from the payment of principal,

Guarantor with or into any other Person, or upon any sale, assignment,
conveyance, transfer, lease or disposition of the property of the Company or any
Subsidiary Guarantor substantially as an entirety to any other Person, any
property or assets of the Company or any Subsidiary Guarantor, as the case may
be, would thereupon become subject to any Lien, then unless such Lien could be
created pursuant to Section 10.14 without equally and ratably securing the
Senior Notes, the Company or such Subsidiary Guarantor, as the case may be,
prior to or simultaneously with such consolidation, merger, sale, assignment,
conveyance, lease, transfer or disposition, will as to such property or assets,
secure the Senior Notes then Outstanding (together with, if the Company or such
Subsidiary Guarantor, as the case may be, shall so determine, any other
Indebtedness of the Company now existing or hereinafter created which is not
subordinate in right of payment to the Senior Notes) equally and ratably with
(or prior to) the Indebtedness which upon such consolidation, sale, assignment,
merger, conveyance, lease, transfer or disposition is to become secured as to
such property or assets by such Lien, or will cause such Senior Notes to be so
secured.

or rescission and any change in the location of any such other office or agency.

     SECTION 10.03. Money for Senior Note Payments to Be Held in Trust.

prior to each due date of the principal of (or premium, if any) or interest or
Liquidated Damages on any Senior Notes, deposit with a Paying Agent a sum

a Subsidiary Guarantor (or any other obligor upon the Senior Notes) in the
making of any payment of principal (and premium, if any) or interest or
Additional Amounts or Liquidated Damages, if any; and

     (c) at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
sums.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (or premium, if any)
or interest or Additional Amounts or Liquidated Damages, if any, on any Senior
Note and remaining unclaimed for three years after such principal, premium or
interest or Additional Amounts or Liquidated Damages, if any, has become due and
payable shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Senior Note
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, (i) in a newspaper published
in the English language, customarily published on each Business Day and of
general circulation in the Borough of Manhattan, The City of New York, and (ii)
in a newspaper published in the Spanish language and of general circulation in
Argentina, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

     SECTION 10.04. Corporate Existence.

     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect the corporate
existence, rights (charter and statutory) and franchises of the Company and each
Subsidiary; provided, however, that the Company shall not be required to
preserve any such right or franchise if the Board of Directors shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Subsidiaries as a whole and that the loss
thereof is not disadvantageous in any material respect to the Holders.

     SECTION 10.05. Payment of Taxes and Other Claims.

     The Company will pay or discharge or cause to be paid or discharged, before
the same shall become delinquent, (a) all taxes, assessments and governmental
charges levied or imposed upon the Company or any Subsidiary or upon the income,
profits or property of the Company or any Subsidiary and (b) all lawful claims
for labor, materials and supplies, which, if unpaid, might by law become a lien
upon the property of the Company or any Subsidiary; provided, however, that the
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings.

     SECTION 10.06. Maintenance of Properties.

     The Company will cause all properties owned by the Company or any
Subsidiary or used or held for use in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall
prevent the Company from discontinuing the maintenance of any of such properties
if such discontinuance is, in the judgment of the Company, desirable in the
conduct of its business or the business of any Subsidiary and not
disadvantageous in any material respect to the Holders.

     SECTION 10.07. Insurance.

     The Company will at all times keep all of its and its Subsidiaries'
properties which are of an insurable nature insured with insurers, believed by
the Company to be responsible, against loss or damage to the extent that
property of similar character is usually so insured by corporations similarly
situated and owning like properties.

     SECTION 10.08. Statement by Officers as to Default.

     (a) The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year and 45 days after the end of each fiscal quarter, a brief
certificate from the principal executive officer, principal financial officer or
principal accounting officer

                                       97

as to his or her knowledge of the Company's compliance with all conditions and
covenants under this Indenture. For purposes of this Section 10.08(a), such
compliance shall be determined without regard to any period of grace or
requirement of notice under this Indenture.

     (b) When any Default has occurred and is continuing under this Indenture,
the Company shall deliver to the Trustee by registered or certified mail or by
telex or facsimile transmission an Officers' Certificate specifying such event
within ten Business Days of its occurrence.

     SECTION 10.09. Payment of Additional Amounts.

     Unless otherwise required by law, all payments made by the Company or any
Subsidiary Guarantor will be made without withholding or deduction for or on
account of any Taxes of whatever nature imposed, levied, collected, withheld or
assessed by or within Argentina or any authority therein or thereof or having
power to tax. In the event any such Taxes are so imposed on any payments made by
the Company or any such Subsidiary Guarantor, the Company or such Subsidiary
Guarantor, as the case may be, will pay such Additional Amounts as may be
necessary in order that the net amounts received by each Holder (including
Additional Amounts) after any withholding or deduction in respect of such Taxes
shall equal the respective amounts of principal, premium, if any, and interest
that would have been received in respect of the Senior Notes in the absence of
such withholding or deduction; except that no such Additional Amounts will be
payable with respect to any withholding or deduction in respect of any payment
under a Senior Note or a Subsidiary Guarantee to, or to a third party on behalf
of, a Holder for or on account of any such Taxes imposed (i) by reason of the
Holder being a resident of Argentina or having some connection with Argentina
(or any political subdivision or authority thereof) other than the mere holding
of such Senior Note or Subsidiary Guarantee or the receipt of any payment
thereunder or the exercise of rights under the Senior Notes, the Subsidiary
Guarantee or the Indenture; (ii) if presentation is required in respect of a
Senior Note or a Subsidiary Guarantee, by reason of presentation by the Holder
for payment on a date more than thirty (30) days after the date on which such
payment became due and payable or the date on which such payment is duly
provided, whichever occurs later, except to the extent that the Holder would
have been entitled to such Additional Amounts on presenting such Senior Note or
Subsidiary Guarantee for payment on the last date of such period of thirty (30)
days; (iii) in respect of any estate, asset (other than Personal Asset Taxes),
inheritance, gift, sales or transfer tax or similar tax assessment or
governmental charge; (iv) any tax, assessment or other governmental charge
(other than Personal Asset Taxes, which is payable otherwise than by withholding
from payments on or in respect of any Senior Note; or (v) any combination of the
reasons set forth in clauses (i), (ii), (iii) or (iv) above. Furthermore, no
Additional Amounts shall be paid to a Holder that is a fiduciary or partnership
or other than the sole beneficial owner of such payment to the extent that a
beneficiary or settlor with respect to such fiduciary or a member of such
partnership or beneficial owner would not have been entitled to receive the
Additional Amounts had such beneficiary, settlor, member or beneficial owner
been the Holder.

                                       98

     At least 30 calendar days prior to each date on which any payment under or
with respect to the Senior Notes is due and payable, if the Company or any
Subsidiary Guarantor, as applicable, will be obligated to pay Additional Amounts
with respect to such payment, the Company or such Subsidiary Guarantor will
deliver to the Trustee an Officers' Certificate stating the fact that such
Additional Amounts will be payable and the amounts so payable and will set forth
such other information necessary to enable the Trustee to pay such Additional
Amounts to Holders on the payment date and specifying the amount required to be
deducted or withheld on the payments of principal and interest (and premium, if
any) due on such payment date for or on account of Taxes and certifying that
such amount will be deducted or withheld and paid by the Company or Subsidiary
Guarantor, as the case may be, to the appropriate taxing or governmental
authority. The Company hereby agrees to indemnify each of the Trustee, the
Principal Paying Agent and each other paying agent for, and to hold it harmless
against any loss, liability, or expense incurred without negligence, bad faith
or wilful misconduct on its part, arising out of or in connection with actions
taken or omitted by it in reliance on any certificate furnished pursuant to this
Section or the failure to furnish such a certificate. The obligations of the
Company under this Section shall survive the payment of the Senior Notes and the
resignation or removal of the Trustee, the Principal Paying Agent or any other
paying agent and the termination of this Indenture. Whenever in the Indenture
there is mentioned, in any context, the payment of principal, premium, if any,
interest or any other amount payable, under or with respect to any Senior Note
or Subsidiary Guarantee, such mention shall be deemed to include mention of the
payment of Additional Amounts to the extent that, in such context, Additional
Amounts are payable in respect thereof.

     If the Company is held liable for any Personal Asset Taxes imposed on the
Holders or direct owners of Senior Notes with respect to the Senior Notes, the
Company has agreed to waive any right that it may have as a matter of Argentine
law to seek reimbursement from such Holders or direct owners of Senior Notes for
any such Personal Asset Taxes paid.

     In addition, the Company will pay any stamp, issue, registration,
documentary or other similar taxes and duties, including interest and penalties,
payable in Argentina or the United States or any political subdivision thereof
or taxing authority thereof or in the foregoing in respect of the creation,
issue and offering of the Senior Notes, and will pay any court, documentary or
similar taxes and duties required to be paid in connection with the enforcement
of the Senior Notes following the incurrence of any Event of Default.

     SECTION 10.10. Limitation on Indebtedness.

     (a) (i) The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume, guarantee or
otherwise become liable with respect to (collectively, "incur") any Indebtedness
(including without limitation Acquired Indebtedness), and (ii) the Company will
not permit any of its Restricted Subsidiaries to issue (except if issued to or
owned beneficially and of record by the Company or any of its Restricted
Subsidiaries) any Preferred Stock; provided that (x) the Company and its
Restricted Subsidiaries may incur Permitted Indebtedness and

                                       99

(y) the Company may incur Indebtedness if, after giving effect thereto, the
Company's Consolidated Fixed Charge Coverage Ratio on the date thereof would be
at least 2.00 to 1.00, determined on a pro forma basis as if the incurrence of
such additional Indebtedness, and the application of the net proceeds therefrom,
had occurred at the beginning of the four-quarter period used to calculate the
Company's Consolidated Fixed Charge Coverage Ratio.

     (b) The Company will not, and will not permit any of Subsidiary Guarantor
to, incur any Indebtedness that is expressly subordinated to any other
Indebtedness of the Company or such Subsidiary Guarantor unless such
Indebtedness by its terms is also expressly made subordinated to the Senior
Notes, in the case of the Company, or the Subsidiary Guarantee, in the case of a
Subsidiary Guarantor.

     SECTION 10.11. Limitation on Restricted Payments.

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, take any of the following actions:

         (i) declare or pay any dividend on, or make any distribution to holders
     of, any shares of the Capital Stock of the Company (other than dividends or
     distributions payable solely in shares of its Qualified Capital Stock or in
     options, warrants or other rights to acquire such shares of Qualified
     Capital Stock);

         (ii) purchase, redeem or otherwise acquire or retire for value,
     directly or indirectly, any shares of Capital Stock of the Company or any
     options, warrants or other rights to acquire such shares of Capital Stock;

         (iii) make any principal payment on, or repurchase, redeem, defease or
     otherwise acquire or retire for value, prior to any scheduled principal
     payment, sinking fund payment or final maturity, any Subordinated
     Indebtedness;

         (iv) make any Investment (other than any Permitted Investment) in any
     Person (including, without limitation, any Unrestricted Subsidiary); or

         (v) (x) declare or pay any dividend or distribution on any Capital
     Stock of any Restricted Subsidiary (other than (I) to the Company or any
     wholly owned Restricted Subsidiary or (II) to all holders of Capital Stock
     of a non-wholly-owned Restricted Subsidiary on a pro rata basis) or (y)
     purchase, redeem or otherwise acquire or retire for value any Capital Stock
     of any Restricted Subsidiary held by any Affiliate of the Company (other
     than another Restricted Subsidiary),

(such payments or other actions described in (but not excluded from) clauses (i)
through (v) are collectively referred to as "RESTRICTED PAYMENTS"), unless at
the time of, and immediately after giving effect to, the proposed Restricted
Payment (the amount of any such Restricted Payment, if other than cash, as
determined by the Board of Directors of the Company, whose determination shall
be conclusive and evidenced by a Board Resolution), (1) no Default or Event of
Default shall have occurred and be continuing,

                                      100

(2) the Company could incur at least US$1.00 of additional Indebtedness (other
than Permitted Indebtedness) pursuant to Section 10.10 hereof and (3) the
aggregate amount of all Restricted Payments declared or made after the first day
of the fiscal quarter of the Company in which the Original Issue Date occurs
shall not exceed the sum of:

         (A) 50% of the Consolidated Net Income of the Company accrued on a
     cumulative basis during the period (taken as one accounting period)
     beginning on the first day of the fiscal quarter of the Company in which
     the Original Issue Date occurs and ending on the last day of the Company's
     latest fiscal quarter ending prior to the date of such proposed Restricted
     Payment for which consolidated financial information for the Company and
     its Restricted Subsidiaries is available (or, if such aggregate cumulative
     Consolidated Adjusted Net Income shall be a loss, minus 100% of such loss),
     plus

         (B) the aggregate net proceeds, including the fair market value of
     property other than cash (as determined by the Board of Directors, whose
     good faith determination will be conclusive; provided that, for any
     property whose fair market value exceeds $2.0 million, either the Company
     shall have completed a Qualified Equity Offering or such fair market value
     shall be confirmed by an independent appraisal from a recognized appraiser
     provided by the Company) received after the Original Issue Date by the
     Company as capital contributions, or from the issuance or sale (other than
     to a Restricted Subsidiary) of shares of Qualified Capital Stock of the
     Company (including upon the exercise of options, warrants or rights) or
     warrants, options or rights to purchase shares of Qualified Capital Stock
     of the Company (excluding any Qualified Capital Stock, or warrants, options
     or rights to purchase shares of Qualified Capital Stock with respect to
     which the purchase price thereof has been financed directly or indirectly
     using funds (x) borrowed from the Company or from any Restricted
     Subsidiary, unless and until and to the extent such borrowing is repaid or
     (y) contributed, extended, guaranteed or advanced by the Company or by any
     Restricted Subsidiary (including, without limitation, in respect of any
     employee stock ownership or benefit plan)), plus

         (C) the aggregate net proceeds, including the fair market value of
     property other than cash (as determined by the Board of Directors, whose
     good faith determination will be conclusive; provided that, for any
     property whose fair market value exceeds $2.0 million, either the Company
     shall have completed a Qualified Equity Offering or such fair market value
     shall be confirmed by an independent appraisal from a recognized appraiser
     provided by the Company) received after the Original Issue Date by the
     Company from the issuance or sale (other than to a Restricted Subsidiary)
     of debt securities or Redeemable Capital Stock that have been converted
     into or exchanged for Qualified Capital Stock of the Company, to the extent
     such securities were originally sold for cash, together with the aggregate
     net cash proceeds received by the Company at the time of such conversion or
     exchange (determined, in the case of net proceeds other than cash as set
     forth above), plus

                                      101

         (D) to the extent not otherwise included in the Consolidated Net Income
     of the Company, an amount equal to the sum of (i) the net reduction in
     Investments in any Person (other than reductions in Permitted Investments)
     resulting from the payment in cash of interest on Indebtedness, dividends,
     repayments of loans or advances, or other transfers of assets, in each case
     to the Company or any Restricted Subsidiary after the Original Issue Date
     from such Person and (ii) the portion (proportionate to the Company's
     equity interest in such Subsidiary) of the Fair Market Value of the net
     assets of any Unrestricted Subsidiary at the time such Unrestricted
     Subsidiary is designated a Restricted Subsidiary; provided, however, that
     in the case of (i) or (ii) above the foregoing sum shall not exceed the
     amount of Investments previously made (and treated as a Restricted Payment)
     by the Company or any Restricted Subsidiary in such Person or Unrestricted
     Subsidiary.

     (b) Notwithstanding paragraph (a) above, the Company and any Restricted
Subsidiary may take the following actions (so long as, with respect to clauses
(iv) and (v) below, no Default or Event of Default shall have occurred and be
continuing):

         (i) the payment of any dividend within 60 days after the date of
     declaration thereof, if at such date of declaration the payment of such
     dividend would have complied with the provisions of paragraph (a) above and
     such payment will be deemed to have been paid on such date of declaration
     for purposes of the calculation required by paragraph (a) above;

         (ii) the purchase, redemption or other acquisition or retirement for
     value of any shares of Capital Stock of the Company in exchange for, or out
     of the net cash proceeds of a substantially concurrent issuance and sale
     (other than to a Restricted Subsidiary) of, shares of Qualified Capital
     Stock of the Company;

         (iii) the purchase, redemption, defeasance or other acquisition or
     retirement for value of any Subordinated Indebtedness in exchange for, or
     out of the net cash proceeds of a substantially concurrent issuance and
     sale (other than to a Restricted Subsidiary) of, shares of Qualified
     Capital Stock of the Company;

         (iv) the purchase, redemption, defeasance or other acquisition or
     retirement for value of Subordinated Indebtedness in exchange for, or out
     of the net cash proceeds of a substantially concurrent incurrence (other
     than to a Restricted Subsidiary) of, new Subordinated Indebtedness so long
     as (A) the principal amount of such new Subordinated Indebtedness does not
     exceed the principal amount (or, if such Subordinated Indebtedness being
     refinanced provides for an amount less than the principal amount thereof to
     be due and payable upon a declaration of acceleration thereof, such lesser
     amount as of the date of determination) of the Subordinated Indebtedness
     being so purchased, redeemed, defeased, acquired or retired, (B) such new
     Subordinated Indebtedness is subordinated to the Senior Notes to the same
     extent as such Subordinated Indebtedness and (C) such new Subordinated
     Indebtedness has (x) an Average Life longer than the Average Life of the
     Subordinated Indebtedness so purchased,

                                      102

     redeemed, defeased, acquired or retired plus one year and (y) a final
     Stated Maturity of principal later than the final Stated Maturity of
     principal of the Subordinated Indebtedness so purchased, redeemed,
     defeased, acquired or retired plus one year; and

         (v) make other Restricted Payments in an aggregate amount not in excess
     of US$5 million.

     The actions described in clauses (ii), (iii) and (v) of this paragraph (b)
shall be Restricted Payments that shall be permitted to be taken in accordance
with this paragraph (b) but shall reduce the amount that would otherwise be
available for Restricted Payments under clause (3) of paragraph (a) above and
the actions described in clause (i) and (iv) of this paragraph (b) shall be
Restricted Payments that shall be permitted to be taken in accordance with this
paragraph (b) and shall not (except, in the case of clause (i), to the extent of
the deemed payment therein described) reduce the amount that would otherwise be
available for Restricted Payments under clause (3) of paragraph (a).

     (c) In computing Consolidated Net Income of the Company under paragraph (a)
above, (1) the Company shall use audited financial statements for the portions
of the relevant period for which audited financial statements are available on
the date of determination and unaudited financial statements and other current
financial data based on the books and records of the Company for the remaining
portion of such period and (2) the Company shall be permitted to rely in good
faith on the financial statements and other financial data derived from the
books and records of the Company that are available on the date of
determination.

     SECTION 10.12. Limitation on Issuances and Sales of Capital Stock of
Restricted Subsidiaries.

     The Company will not permit any Restricted Subsidiary to issue or sell any
Capital Stock (other than to the Company or a wholly-owned Restricted
Subsidiary); provided, however, that this covenant shall not prohibit any
issuance or sale of the Capital Stock of any Restricted Subsidiary if
immediately after giving effect to such issuance or sale, such Restricted
Subsidiary would no longer constitute a Restricted Subsidiary and any Investment
in such Person remaining after giving effect to such issuance or sale would have
been permitted to be made under Section 10.11 hereof if made on the date of such
issuance or sale.

     SECTION 10.13. Limitation on Transactions with Affiliates.

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into or suffer to exist any transaction or series
of related transactions (each of the foregoing, an "AFFILIATE TRANSACTION")
(including, without limitation, the sale, purchase, exchange or lease of assets,
property or services) with, or for the benefit of, any Affiliate of the Company
or any Restricted Subsidiary (other than Exempted Affiliate Transactions),
unless (i) such Affiliate Transaction is fair from a financial point of view to
the Company or such Restricted Subsidiary, as the case may be, and is on

                                      103

terms that are no less favorable to the Company or such Restricted Subsidiary,
as the case may be, than those that could have been obtained in an arms-length
transaction with third parties that are not Affiliates, (ii) with respect to any
Affiliate Transaction involving aggregate consideration equal to or greater than
US$5 million (or, to the extent non-US Dollar denominated, the US Dollar
Equivalent of such amount), the Company will deliver an officer's certificate to
the Trustee certifying that such Affiliate Transaction complies with clause (i)
above and such Affiliate Transaction has been approved by a majority of the
Disinterested Directors of the Company or, in the event no members of the Board
of Directors of the Company are Disinterested Directors with respect to any
Affiliate Transaction included in this clause (ii), the Company will obtain a
written opinion from a recognized U.S. investment banking firm, appraisal firm
or independent public accounting firm certifying that such Affiliate Transaction
is fair to the Company or its Restricted Subsidiary, as the case may be, from a
financial point of view and (iii) with respect to any Affiliate Transaction
involving aggregate consideration in excess of US$10 million (or, to the extent
non-US Dollar denominated, the US Dollar Equivalent of such amount), the Company
will obtain a written opinion from a recognized United States investment banking
firm, appraisal firm or independent public accounting firm to the effect set
forth in the preceding clause (ii).

     SECTION 10.14. Limitation on Liens.

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, create, incur, assume or suffer to exist any Lien of any
kind (other than Permitted Liens) on or with respect to any of its property or
assets, including any shares of stock or indebtedness of any Restricted
Subsidiary, whether owned at the Original Issue Date or thereafter acquired, or
any income, profits or proceeds therefrom, or assign or otherwise convey any
right to receive income thereon, unless (x) in the case of any Lien securing
Subordinated Indebtedness, the Senior Notes are secured by a Lien on such
property, assets or proceeds that is senior in priority to such Lien and (y) in
the case of any other Lien, the Senior Notes are equally and ratably secured
with the obligation or liability secured by such Lien.

     SECTION 10.15. Limitation on Issuances of Guarantees by Restricted
Subsidiaries.

     The Company will not permit any Restricted Subsidiary, directly or
indirectly, to Guarantee any Indebtedness of the Company which is pari passu
with or subordinate in right of payment to the Senior Notes ("OTHER GUARANTEED
INDEBTEDNESS"), unless (i) such Guarantee is otherwise permitted under the terms
of this Indenture, (ii) such Restricted Subsidiary simultaneously executes and
delivers a supplemental indenture to this Indenture providing for a Guarantee of
the Senior Notes by such Restricted Subsidiary and (iii) such Restricted
Subsidiary waives and will not in any manner whatsoever claim or take the
benefit or advantage of, any rights of reimbursement, indemnity or subrogation
or any other rights against the Company or any other Restricted Subsidiary as a
result of any payment by such Restricted Subsidiary under its Subsidiary
Guarantee. If the Other Guaranteed Indebtedness is (A) pari passu with the
Senior Notes, then the guarantee of such Other Guaranteed Indebtedness shall be
pari passu

                                      104

with, or subordinated to, such Subsidiary Guarantee, or (B) subordinated to the
Senior Notes, then the guarantee of such Other Guaranteed Indebtedness shall be
subordinated to the Subsidiary Guarantee at least to the extent that the Other
Guaranteed Indebtedness is subordinated to the Senior Notes.

     Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary may provide by its terms that it shall be automatically and
unconditionally released and discharged upon (i) any sale, exchange or transfer,
to any Person not an Affiliate of the Company, of all of the Company's and each
Restricted Subsidiary's Capital Stock in, or all or substantially all the assets
of, such Restricted Subsidiary (which sale, exchange or transfer is not
prohibited by the Indenture) or (ii) the release or discharge of the Guarantee
which resulted in the creation of such Subsidiary Guarantee, except a discharge
or release by or as a result of payment by such Restricted Subsidiary under such
Guarantee.

     SECTION 10.16. Purchase of Senior Notes upon a Change of Control.

     (a) If a Change of Control shall occur at any time, then each Holder of
Senior Notes shall have the right to require that the Company purchase such
Holder's Senior Notes, in whole or in part in integral multiples of US$1,000, at
a purchase price (the "CHANGE OF CONTROL PURCHASE PRICE") in cash in an amount
equal to 101% of the principal amount thereof, plus accrued interest, if any, to
the date of purchase (the "CHANGE OF CONTROL PURCHASE DATE"), pursuant to the
offer and the other procedures described in paragraphs (b) and (c) of this
Section (the "CHANGE OF CONTROL OFFER").

     (b) Within 30 days following any Change of Control, the Company shall
notify the Trustee in writing thereof and give written notice of such Change of
Control to each Holder of Senior Notes in the manner provided in Section 1.06,
stating:

         (i) that a Change in Control has occurred and that such Holder has the
     right to require the Company to repurchase such Holder's Senior Notes at
     the Change of Control Purchase Price;

         (ii) the circumstances and relevant facts regarding such Change in
     Control (including but not limited to information with respect to pro forma
     historical income, cash flow and capitalization after giving effect to such
     Change in Control);

         (iii) the Change of Control Purchase Price and the Change of Control
     Purchase Date, which shall be a Business Day no earlier than 30 days nor
     later than 60 days from the date such notice is mailed;

         (iv) that all Senior Notes validly tendered will be accepted for
     payment and that any Senior Note not tendered shall continue to accrue
     interest;

         (v) that, unless the Company defaults in the payment of the Change of
     Control Purchase Price, any Senior Notes accepted for payment pursuant to

                                      105

     the Change of Control Offer shall cease to accrue interest after the Change
     of Control Purchase Date; and

         (vi) the instructions that a Holder of Senior Notes must follow to
     accept a Change of Control Offer or to withdraw such acceptance in
     accordance with paragraph (c) of this Section.

     (c) Holders electing to have Senior Notes purchased will be required to
surrender such Senior Notes to the Company at the address specified in the
notice at least five Business Days prior to the Change of Control Purchase Date.
Holders will be entitled to withdraw their election if the Company receives, not
later than three Business Days prior to the Change of Control Purchase Date, a
telex, facsimile transmission or letter setting forth the name of the Holder,
the principal amount of the Senior Notes delivered for purchase by the Holder as
to which his election is to be withdrawn and a statement that such Holder is
withdrawing his election to have such Senior Notes purchased. Holders whose
Senior Notes are purchased only in part will be issued new Senior Notes equal in
principal amount to the unpurchased portion of the Senior Notes surrendered.

     (d) The Company shall not, and shall not permit any Restricted Subsidiary
to, create or permit to exist or become effective any restriction (other than
restrictions existing under Indebtedness as in effect on the Original Issue Date
and any refinancings thereof) that would materially impair the ability of the
Company to make a Change of Control Offer to purchase the Senior Notes or, if
such Change of Control Offer is made, to pay for the Senior Notes tendered for
purchase.

     SECTION 10.17. Limitation on Sale of Assets.

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
engage in any Asset Sale unless (i) the consideration received by the Company or
such Restricted Subsidiary for such Asset Sale is not less than the Fair Market
Value of the assets sold, (ii) the aggregate Fair Market Value of the
consideration received from any Asset Sale that is not in the form of cash or
Cash Equivalents shall not, when aggregated with the Fair Market Value of all
other non-cash consideration received by the Company and its Restricted
Subsidiaries from all previous Asset Sales since the Original Issue Date that
have not, prior to such date, been converted to cash or Cash Equivalents, exceed
five percent of the Consolidated Tangible Assets of the Company at the time of
the Asset Sale under consideration; and provided, that, with respect to any
Asset Sales to Affiliates of the Company, the Company receives consideration
consisting of no less than 85% cash or Cash Equivalents and (iii) immediately
before and immediately giving effect to such Asset Sale, no Default or Event of
Default shall have occurred and be continuing. For purposes of clause (ii)
above, any Indebtedness or other liabilities (as shown on the Company's or such
Subsidiary's most recent balance sheet) of the Company or any Subsidiary (other
than contingent liabilities) that are assumed by the transferee in connection
with an Asset Sale shall be deemed to be Cash Equivalents, but only to the
extent such assumption is effected on a basis under which there is no recourse
to the

                                      106

Company or any Subsidiary of the Company with respect to such Indebtedness or
other liabilities.

     (b) If the Company or any Restricted Subsidiary engages in an Asset Sale,
the Company may use the Net Cash Proceeds thereof, within 12 months after such
Asset Sale, to (i) permanently repay or prepay any then outstanding senior
Indebtedness of the Company or senior Indebtedness of any Restricted Subsidiary
or (ii) invest (or enter into a legally binding commitment to invest) in
properties and assets to replace the properties and assets that were the subject
of the Asset Sale or in properties and assets that will be used in any line or
lines of business of the Company or its Restricted Subsidiaries on the Original
Issue Date or which are related, ancillary or complementary thereto; provided
that any such investment shall be completed within 24 months of such Asset Sale.
The amount of such Net Cash Proceeds not so used as set forth above in this
paragraph (b) constitutes "EXCESS PROCEEDS" provided that no investment
commitment referred to in clause (ii) above shall constitute a use of Net Cash
Proceeds unless such Net Cash Proceeds are actually so invested within 24 months
of such Asset Sale.

     (c) When the aggregate amount of Excess Proceeds exceeds US$5 million (or,
to the extent non-US Dollar denominated, the US Dollar Equivalent of such
amount), the Company shall, within 20 business days, make an offer to purchase
(an "EXCESS PROCEEDS OFFER") from all holders of Senior Notes and from the
holders of Pari Passu Indebtedness of the Company, to the extent required by the
terms thereof, on a pro rata basis, in accordance with the procedures set forth
in this Indenture or the agreements governing any such Pari Passu Indebtedness,
the maximum principal amount (expressed as a multiple of US$1,000) of Senior
Notes and any such other Pari Passu Indebtedness that may be purchased with the
Excess Proceeds. The offer price as to each Senior Note and any such other Pari
Passu Indebtedness shall be payable in cash (the "OFFERED PRICE") in an amount
equal to (solely in the case of the Senior Notes) 100% of the principal amount
of such Senior Note and (solely in the case of such other Pari Passu
Indebtedness) no greater than 100% of the principal amount (or accreted value,
as applicable) of such Pari Passu Indebtedness, plus in each case accrued
interest, if any, and any Liquidated Damages and Additional Amounts with respect
thereto to the date such Excess Proceeds Offer is consummated. To the extent
that the aggregate principal amount of Senior Notes and any such other Pari
Passu Indebtedness tendered pursuant to an Excess Proceeds Offer is less than
the Excess Proceeds, the Company may use the portion of the Excess Proceeds not
required to be used to repurchase the Senior Notes and such other Pari Passu
Indebtedness for general corporate purposes. If the aggregate principal amount
of Senior Notes and any such other Pari Passu Indebtedness validly tendered and
not withdrawn by holders thereof exceeds the Excess Proceeds, the Senior Notes
and any such other Pari Passu Indebtedness to be purchased will be selected on a
pro rata basis (based upon the principal amount of Senior Notes and the
principal amount or accreted value of such other Pari Passu Indebtedness
tendered by each holder). Upon completion of such Exceeds Proceeds Offer, the
amount of Excess Proceeds shall be reset to zero.

     (d) The Company shall, within the time period provided in paragraph (c)
above, notify the Trustee in writing of any Excess Proceeds Offer and shall give
written

                                      107

notice of such Excess Proceeds Offer to each Holder of Senior Notes in the
manner provided in Section 1.06 stating:

         (i) that the Holder has the right to require the Company to repurchase
     such Holder's Senior Notes at the Offered Price (including any Liquidated
     Damages and Additional Amounts) subject to proration in the event the
     Excess Proceeds are less than the aggregate Offered Price (including any
     Liquidated Damages and Additional Amounts) of all Senior Notes and Pari
     Passu Indebtedness tendered;

         (ii) the date of purchase of Senior Notes pursuant to the Excess
     Proceeds Offer (the "ASSET SALE PURCHASE DATE"), which shall be no earlier
     than 30 days nor later than 60 days from the date such notice is mailed, or
     such later date as is necessary to comply with requirements under the
     Exchange Act or any applicable securities laws or regulations;

         (iii) that any Senior Note not tendered will continue to accrue
     interest;

         (iv) that, unless the Company defaults in the payment of the Offered
     Price, any Senior Note accepted for payment pursuant to the Excess Proceeds
     Offer shall cease to accrue interest after the Asset Sale Purchase Date;
     and

         (v) the instructions a Holder must follow to accept an Excess Proceeds
     Offer or to withdraw such acceptance in accordance with paragraph (e) of
     this Section.

     (e) Holders electing to have Senior Notes purchased will be required to
surrender such Senior Notes to the Company at the address specified in the
notice at least five Business Days prior to the Asset Sale Purchase Date.
Holders will be entitled to withdraw their election if the Company receives, not
later than three Business Days prior to the Asset Sale Purchase Date, a telex,
facsimile transmission or letter setting forth the name of the Holder, the
principal amount of the Senior Notes delivered for purchase by the Holder as to
which his election is to be withdrawn and a statement that such Holder is
withdrawing his election to have such Senior Notes purchased. Holders whose
Senior Notes are purchased only in part will be issued new Senior Notes equal in
principal amount to the unpurchased portion of the Senior Notes surrendered.

     SECTION 10.18. Limitation on Sale and Leaseback Transactions.

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into any Sale and Leaseback Transaction with
respect to any property or assets (whether now owned or hereafter acquired),
unless (i) the sale or transfer of such property or assets to be leased is
treated as an Asset Sale and the Company complies with Section 10.17 with
respect thereto, (ii) the Company or such Restricted Subsidiary would be
permitted to incur Indebtedness under clause (a) of Section 10.10 in the amount
of the Attributable Value incurred in respect of such Sale and Leaseback
Transaction and (iii) the Company or such Restricted Subsidiary would be
permitted to grant a Lien under

                                      108

Section 10.14 to secure the amount of the Attributable Value in respect of such
Sale and Leaseback Transaction.

     SECTION 10.19. Limitation on Dividend and Other Payment Restrictions
Affecting Restricted Securities.

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, create or otherwise cause or suffer to exist or become
effective any encumbrance or restriction of any kind on the ability of any
Restricted Subsidiary to (a) pay dividends, in cash or otherwise, or make any
other distributions on or in respect of its Capital Stock, (b) pay any
Indebtedness owed to the Company or any other Restricted Subsidiary, (c) make
loans or advances to the Company or any other Restricted Subsidiary, or (d)
transfer any of its properties or assets to the Company or any other Restricted
Subsidiary (other than customary restrictions on transfers of property subject
to a Lien permitted under this Indenture that would not materially adversely
affect the Company's ability to satisfy its obligations under the Senior Notes
and this Indenture), except for such encumbrances or restrictions existing under
or by reason of (i) any agreement in effect on the Original Issue Date (any such
agreement which relates to a US Dollar amount in excess of US$1,000,000 (or, to
the extent non-US Dollar denominated, the US Dollar Equivalent of such amount)
being listed on a schedule attached thereto), (ii) applicable law, (iii)
customary provisions restricting subletting or assignment of any lease or
assignment of any other contract to which the Company or any Restricted
Subsidiary is a party or to which any of their respective properties or assets
are subject, (iv) any agreement or other instrument of a Person, or binding with
respect to assets, acquired by the Company or any Restricted Subsidiary in
existence at the time of such acquisition (but not created in contemplation
thereof), which encumbrance or restriction is not applicable to any Person, or
the properties or assets of any Person, other than the Person, or the property
or assets of the Person, or such assets, so acquired, (v) any encumbrance or
restriction contained in contracts for sales of assets permitted by Section
10.17 hereof with respect to the assets to be sold pursuant to such contract,
(vi) any agreement providing for the incurrence of Indebtedness by a Restricted
Subsidiary in compliance with Section 10.10 hereof, provided that such
Restricted Subsidiary is or becomes at the time of such agreement a Subsidiary
Guarantor; (vii) any agreement pursuant to which Indebtedness was issued if (A)
the encumbrance or restriction applies only in the event of a payment default or
a default with respect to a financial covenant contained in such Indebtedness,
(B) the encumbrance or restriction is not materially more disadvantageous to the
holders of the Senior Notes than is customary in comparable financings (as
determined by the Company) and (C) the Company determines that any such
encumbrance or restriction will not materially affect the Company's ability to
make principal or interest payments on the Senior Notes, and (viii) any
encumbrance or restriction existing under any agreement that extends, renews,
refinances or replaces the agreements containing the encumbrances or
restrictions in the foregoing clauses (i) and (vii); provided that the terms and
conditions of any such encumbrances or restrictions are not materially less
favorable to the holders of the Senior Notes than those under or pursuant to the
agreement so extended, renewed, refinanced or replaced.

                                      109

     SECTION 10.20. Provision of Reports and Financial Statements.

     (a) The Company shall provide to the Trustee, holders of Senior Notes and
the Initial Purchaser: (i) within 120 days after the end of each fiscal year of
the Company, audited consolidated financial statements of the Company for such
fiscal year and (ii) within 60 days after the end of each of the first three
fiscal quarters of the Company, unaudited consolidated financial statements of
the Company for such fiscal quarter. Each of the financial statements referred
to in (i) and (ii) shall be prepared in accordance with Argentine GAAP
consistently applied, shall be translated into English, and shall be accompanied
by a discussion and analysis, substantially in the format of the "Management's
Discussion and Analysis of Financial Condition and Results of Operations" that
would be included in a Form 20-F filed under the Exchange Act, except that such
discussion and analysis will be required only to compare the financial condition
and results of operations of the fiscal year or fiscal quarter most recently
ended to the prior fiscal year or comparable fiscal quarter of the prior fiscal
year, as applicable. The financial statements referred to in (i) shall contain a
reconciliation to U.S. GAAP of net income and shareholders' equity and a report
thereon by the Company's independent auditors. In addition, from and after the
earlier of (i) the date of the commencement of the Exchange Offer or the
effectiveness of the Shelf Registration Statement and (ii) September 30, 1998 in
either case, whether or not required by the rules and regulations of the U.S.
Securities and Exchange Commission (the "Commission"), the Company will file a
copy of all such information and reports with the Commission for public
availability (unless the Commission will not accept such a filing) and make such
information and reports available to securities analysts, broker-dealers and
prospective investors upon request. In addition, the Company shall provide to
the Trustee, holders of Senior Notes and the Initial Purchaser an English
translation of each document filed by the Company with the CNV and made publicly
available in Argentina. Furthermore, for so long as any of the Senior Notes
remain outstanding, the Company has agreed to make available to any prospective
purchaser of the Senior Notes, upon request by a holder, or to any beneficial
owner of the Senior Notes in connection with any sale thereof, the information
required by Rule 144A(d)(4) under the Securities Act.

     (b) The Company and any Subsidiary Guarantors shall at all times comply
with the periodic reporting requirements of the CNV and the BASE as in effect at
the time of reporting.

     (c) The Company's delivery of such reports, information and documents to
the Trustee is for informational purposes only and the Trustee's receipt of such
shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

     SECTION 10.21. Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Section 8.03 or Section 10.07 or Sections
10.10

                                      110

through 10.14, inclusive, or Sections 10.17 through 10.19, inclusive, if before
or after the time for such compliance the Holders of at least a majority in
principal amount of the Outstanding Senior Notes, by Act of such Holders, waive
such compliance in such instance with such term, provision or condition, but no
such waiver shall extend to or affect such term, provision or condition except
to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                                   ARTICLE 11
                           REDEMPTION OF SENIOR NOTES

     SECTION 11.01. Optional Redemption.

     (a) The Senior Notes will be redeemable, at the Company's option, in whole
or in part, at any time or from time to time, on or after April 1, 2003, and
prior to maturity, upon not less than 30 nor more than 60 days' prior notice, at
the following redemption prices (expressed in percentages of principal amount),
plus accrued and unpaid interest, including Liquidated Damages, if any, to the
redemption date, if redeemed during the 12-month period commencing April 1 of
the years set forth below:

          YEAR                                               REDEMPTION PRICE
          ----                                               ----------------
          2003                                                   105.875%
          2004                                                   103.917%
          2005                                                   101.958%
          2006 and hereafter                                     100.000%

Any such redemption shall be made on a pro rata basis among all holders of
Senior Notes.

     (b) At anytime on or prior to April 1, 2001, the Company may redeem up to
35% of the original aggregate principal amount of the Senior Notes within 60
days after any sale (other than to a Restricted Subsidiary) of Capital Stock
(other than Redeemable Capital Stock) with the net proceeds of such sale at a
redemption price equal to 111.75% of the principal amount thereof, together with
accrued interest, if any, to the Redemption Date (subject to the right of
Holders of record on relevant record dates to receive interest due on relevant
Interest Payment Dates), provided that no less than US$100 million aggregate
principal amount of the Senior Notes remains Outstanding immediately after the
occurrence of any such redemption. Any such redemption shall be made on a pro
rata basis among all holders of Senior Notes.

     (c) If at any time after the Original Issue Date and prior to April 1, 2003
as a result of a Change in Law, the Company becomes obligated to pay any
Additional Amounts or any Personal Asset Taxes and such obligation cannot be
avoided by the Company taking reasonable measures available to it, then the
Senior Notes will be redeemable as a whole (but not in part), at the option of
the Company, at any time upon

                                      111

not less than thirty (30) days nor more than sixty (60) days' notice given to
the Holders as provided herein at their principal amount together with accrued
interest thereon to the Redemption Date. The Company will also pay to the
holders on the Redemption Date any Additional Amounts which are then payable. In
order to effect such a redemption of the Senior Notes, the Company will be
required to deliver to the Trustee at least forty-five (45) days prior to the
Redemption Date an Officer's Certificate to the effect that the Company's
obligation to pay Additional Amounts or Personal Asset Taxes, as the case may
be, cannot be avoided by the Company taking reasonable measures available to it
and an opinion of independent legal counsel of recognized standing to the effect
that the Company has or will become obligated to pay such Additional Amounts or
Personal Asset Taxes, as the case may be, as a result of such Change in Law. No
notice of redemption may be given earlier than sixty (60) days prior to the
earliest date on which the Company would be obligated to pay such Additional
Amounts or Personal Asset Taxes, as the case may be, were a payment in respect
of the Senior Notes then due.

     SECTION 11.02. Applicability of Article.

     Redemption of Senior Notes at the election of the Company or otherwise, as
permitted or required by any provision of this Indenture, shall be made in
accordance with such provision and this Article.

     SECTION 11.03. Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Senior Notes pursuant to Section
11.01 shall be evidenced by a Board Resolution. Except as otherwise provided in
Section 11.01(b), in case of any redemption at the election of the Company, the
Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and of the principal amount of Senior Notes
to be redeemed and shall deliver to the Trustee such documentation and records
as shall enable the Trustee to select the Senior Notes to be redeemed pursuant
to Section 11.04.

     SECTION 11.04. Selection by Trustee of Senior Notes to Be Redeemed.

     If less than all the Senior Notes are to be redeemed, the particular Senior
Notes to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Senior Notes not previously
called for redemption, by such method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
of the principal of Senior Notes; provided, however, that no such partial
redemption shall reduce the portion of the principal amount of a Senior Note not
redeemed to less than $1,000.

     The Trustee shall promptly notify the Company in writing of the Senior
Notes selected for redemption and, in the case of any Senior Notes selected for
partial redemption, the principal amount thereof to be redeemed.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to redemption of Senior Notes shall relate, in the case
of any Senior

                                      112

Note redeemed or to be redeemed only in part, to the portion of the principal
amount of such Senior Note which has been or is to be redeemed.

     SECTION 11.05. Notice of Redemption.

     Notice of redemption shall be given in the manner provided for in Section
1.06 not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Senior Notes to be redeemed.

     All notices of redemption shall include the "CUSIP" number and "CINS"
number shall state:

         (a) the Redemption Date,

         (b) the Redemption Price and the amount of accrued interest to the
     Redemption Date payable as provided in Section 11.07, if any,

         (c) if less than all Outstanding Senior Notes are to be redeemed, the
     identification (and, in the case of a partial redemption, the principal
     amounts) of the particular Senior Notes to be redeemed,

         (d) in case any Senior Note is to be redeemed in part only, the notice
     which relates to such Senior Note shall state that on and after the
     Redemption Date, upon surrender of such Senior Note, the holder will
     receive, without charge, a new Senior Note or Senior Notes of authorized
     denominations for the principal amount thereof remaining unredeemed,

         (e) that on the Redemption Date the Redemption Price (and accrued
     interest, if any, to the Redemption Date payable as provided in Section
     11.07) will become due and payable upon each such Senior Note, or the
     portion thereof, to be redeemed, and that interest thereon will cease to
     accrue on and after said date, and

         (f) the place or places where such Senior Notes are to be surrendered
     for payment of the Redemption Price and accrued interest, if any.

     Notice of redemption of Senior Notes to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request made at least
ten (10) days prior to the latest date notice to the Holders may be timely
given, by the Trustee in the name and at the expense of the Company.

     SECTION 11.06. Deposit of Redemption Price.

     Prior to 12 Noon (New York City time) one Business Day prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 10.03) an amount of money sufficient to pay the
Redemption Price of, and any applicable Additional Amounts and accrued interest
and Liquidated Damages on, all the Senior Notes which are to be redeemed on that
date.

                                      113

     SECTION 11.07. Senior Notes Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Senior Notes so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified (together with accrued interest, if any, to
the Redemption Date), and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such Senior
Notes shall cease to bear interest. Upon surrender of any such Senior Note for
redemption in accordance with said notice, such Senior Note shall be paid by the
Company at the Redemption Price, together with accrued interest, if any, to the
Redemption Date; provided, however, that installments of interest whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the Holders
of such Senior Notes, or one or more Predecessor Senior Notes, registered as
such at the close of business on the relevant Record Dates according to their
terms and the provisions of Section 3.07.

     If any Senior Note called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the
Senior Notes.

     SECTION 11.08. Senior Notes Redeemed in Part.

     Any Senior Note which is to be redeemed only in part shall be surrendered
at the office or agency of the Company maintained for such purpose pursuant to
Section 10.02 (with due endorsement by, or a written instrument of transfer in
form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or such Holders attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Senior Note without service charge, a new Senior Note or Senior Notes, of
any authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Senior Note so surrendered.

                                   ARTICLE 12
                         GUARANTEES OF THE SENIOR NOTES

     SECTION 12.01. Guarantee.

     Subject to the provisions of this Article Twelve, and as permitted by
Article 3 of the Argentine Negotiable Obligations Law, the Company will require
that any Subsidiary Guarantor which undertakes a Guarantee of the Senior Notes
will unconditionally and irrevocably guarantee to each Holder of a Senior Note
authenticated and delivered by the Trustee and to the Trustee and its successors
and assigns, irrespective of the validity and enforceability of this Indenture,
the Senior Notes or the obligations of the Company or any other subsequent
Subsidiary Guarantors to the Holders or the Trustee hereunder or thereunder,
that: (a) the principal of, premium, if any, and interest on the Senior Notes
(and any Additional Amounts payable thereon and any Liquidated Damages) shall be
duly and punctually paid in full when due, whether at maturity, upon redemption
at the

                                      114

option of Holders pursuant to the provisions of the Senior Notes relating
thereto, by acceleration or otherwise, and interest on the overdue principal and
(to the extent permitted by law) interest, if any, on the Senior Notes and all
other obligations of the Company or any subsequent Subsidiary Guarantors to the
Holders or the Trustee hereunder or thereunder (including amounts due the
Trustee under Section 6.06 and Section 10.09 hereof) and all other Indenture
Obligations shall be promptly paid in full or performed, all in accordance with
the terms hereof and thereof; and (b) in case of any extension of time of
payment or renewal of any Senior Notes or any of such other Indenture
Obligations, the same shall be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at Stated
Maturity, by acceleration or otherwise. Failing payment when due of any amount
so guaranteed, or failing performance of any other obligation of the Company to
the Holders, for whatever reason, such Subsidiary Guarantor shall be obligated
to pay, or to perform or cause the performance of, the same immediately. An
Event of Default under this Indenture or the Senior Notes shall constitute an
event of default under this Guarantee, and shall entitle the Holders of Senior
Notes to accelerate the obligations of such Subsidiary Guarantor hereunder in
the same manner and to the same extent as the obligations of the Company.

     The Company will require that any such Subsidiary Guarantor agrees that its
obligations hereunder shall be unconditional, irrespective of the validity,
regularity or enforceability of the Senior Notes or this Indenture, the absence
of any action to enforce the same, any waiver or consent by any Holder of the
Senior Notes with respect to any provisions hereof or thereof, any release of
any other Subsidiary Guarantor, the recovery of any judgment against the
Company, any action to enforce the same, whether or not a Guarantee is affixed
to any particular Senior Note, or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor. Any such
Subsidiary Guarantor will waive the benefit of diligence, presentment, demand of
payment, filing of claims with a court in the event of insolvency or bankruptcy
of the Company, any right to require a proceeding first against the Company,
protest, notice and all demands whatsoever and covenants that its Guarantee
shall not be discharged except by complete performance of the obligations
contained in the Senior Notes, this Indenture and this Guarantee. Any such
Subsidiary Guarantor will acknowledge that the Guarantee is a guarantee of
payment and not of collection. If any Holder or the Trustee is required by any
court or otherwise to return to the Company or to any Subsidiary Guarantor, or
any custodian, trustee, liquidator or other similar official acting in relation
to the Company or any Subsidiary Guarantor, any amount paid by the Company or
such Subsidiary Guarantor to the Trustee or such Holder, this Guarantee, to the
extent theretofore discharged, shall be reinstated in full force and effect. Any
such Subsidiary Guarantor will further agree that, as between it, on the one
hand, and the Holders of Senior Notes and the Trustee, on the other hand, (a)
subject to this Article Twelve, the maturity of the obligations guaranteed
hereby may be accelerated as provided in Article Five hereof for the purposes of
this Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby,
and (b) in the event of any acceleration of such obligations as provided in
Article Five hereof, such obligations (whether or not due and payable) shall
forthwith become due and payable by any such Subsidiary Guarantor for the
purpose of this Guarantee.

                                      115

     Such Guarantee shall remain in full force and effect and continue to be
effective should any petition be filed by or against the Company for liquidation
or reorganization, should the Company become insolvent or make an assignment for
the benefit of creditors or should a receiver or trustee be appointed for all or
any significant part of the Company's assets, and shall, to the fullest extent
permitted by law, continue to be effective or be reinstated, as the case may be,
if at any time payment and performance of the Senior Notes are, pursuant to
applicable law, rescinded or reduced in amount, or must otherwise be restored or
returned by any obligee on the Senior Notes, whether as a "VOIDABLE PREFERENCE",
"FRAUDULENT TRANSFER" or otherwise, all as though such payment or performance
had not been made. In the event that any payment, or any part thereof, is
rescinded, reduced, restored or returned, the Senior Notes shall, to the fullest
extent permitted by law, be reinstated and deemed reduced only by such amount
paid and not so rescinded, reduced, restored or returned.

     SECTION 12.02. Execution and Delivery of Guarantee.

     To further evidence the Guarantee set forth in Section 12.01, each
Subsidiary Guarantor, if any, will agree that a notation of such Guarantee,
substantially in the form included in Exhibit A of this Indenture, shall be
endorsed on each Senior Note authenticated and delivered by the Trustee. Such
Guarantee shall be executed on behalf of any Subsidiary Guarantor by either
manual or facsimile signature of two Officers of such Subsidiary Guarantor, each
of whom, in each case, shall have been duly authorized to so execute by all
requisite corporate action. The validity and enforceability of any Guarantee
shall not be affected by the fact that it is not affixed to any particular
Senior Note.

     Any Subsidiary Guarantor will agree that its Guarantee set forth in Section
12.01 shall remain in full force and effect notwithstanding any failure to
endorse on each Senior Note a notation of such Guarantee.

     If an Officer of any Subsidiary Guarantor whose signature is on a Guarantee
no longer holds that office at the time the Trustee authenticates the Senior
Note on which such Guarantee is endorsed or at any time thereafter, such
Subsidiary Guarantor's Guarantee of such Senior Note shall be valid
nevertheless.

     The delivery of any Senior Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Indenture on behalf of the Subsidiary Guarantor.

     SECTION 12.03. Release of a Subsidiary Guarantor.

     (a) If no Default exists or would exist under this Indenture, upon the sale
or disposition of all of the Capital Stock of any Subsidiary Guarantor by the
Company or a Restricted Subsidiary of the Company in a transaction constituting
an Asset Sale the Net Cash Proceeds of which are applied in accordance with
Section 10.16, or upon the consolidation or merger of any Subsidiary Guarantor
with or into any person in compliance with Article Eight (in each case, other
than to the Company or an Affiliate of

                                      116

the Company or a Restricted Subsidiary), such Subsidiary Guarantor and each
Subsidiary of the Subsidiary Guarantor that is also a Subsidiary Guarantor shall
be deemed automatically and unconditionally released and discharged from all
obligations under this Article Twelve without any further action required on the
part of the Trustee or any Holder; provided, however, that the Subsidiary
Guarantor is sold or disposed of in accordance with this Indenture.

     (b) The Trustee shall deliver an appropriate instrument evidencing the
release of the Subsidiary Guarantor upon receipt of a request of the Company or
the Subsidiary Guarantor accompanied by an Officers' Certificate and an Opinion
of Counsel certifying as to the compliance with this Section 12.03. Any
Subsidiary Guarantor not so released or the entity surviving such Subsidiary
Guarantor, as applicable, shall remain or be liable under its Guarantee as
provided in this Article Twelve.

     The Trustee shall execute any documents reasonably requested by the Company
or any Subsidiary Guarantor in order to evidence the release of such Subsidiary
Guarantor from its obligations under its Guarantee and under this Article
Twelve.

     Except as set forth in Articles Eight and Ten and this Section 12.03,
nothing contained in this Indenture or in any of the Senior Notes shall prevent
any consolidation or merger of any Subsidiary Guarantor with or into the Company
or shall prevent any sale or conveyance of the property of the Subsidiary
Guarantor as an entirety or substantially as an entirety to the Company.

     SECTION 12.04. Waiver of Subrogation.

     Until this Indenture is discharged and all of the Senior Notes are
discharged and paid in full, any Subsidiary Guarantor will irrevocably waive and
agree not to exercise any claim or other rights which it may have at the time
such Guarantee is made or thereafter acquire against the Company that arise from
the existence, payment, performance or enforcement of the Company's obligations
under the Senior Notes or this Indenture and the Subsidiary Guarantor's
obligations under this Guarantee and this Indenture, in any such instance
including, without limitation, any right of subrogation, reimbursement,
exoneration, contribution, indemnification, and any right to participate in any
claim or remedy of the Guaranteed Parties against the Company, whether or not
such claim, remedy or right arises in equity, or under contract, statute or
common law, including, without limitation, the right to take or receive from the
Company, directly or indirectly, in cash or other property or by set-off or in
any other manner, payment or security on account of such claim or other rights.
If any amount shall be paid to the Subsidiary Guarantor in violation of the
preceding sentence and any amounts owing to the Trustee or the Holders of Senior
Notes under the Senior Notes, this Indenture, or any other document or
instrument delivered under or in connection with such agreements or instruments,
shall not have been paid in full, such amount shall have been deemed to have
been paid to the Subsidiary Guarantor for the benefit of, and held in trust for
the benefit of, the Guaranteed Parties and shall forthwith be paid to the
Trustee for the benefit of such Holders to be credited and applied to the
obligations in favor of the Guaranteed Parties, whether matured or unmatured, in
accordance with the terms of this

                                      117

Indenture. The Subsidiary Guarantor will acknowledge that it will receive direct
and indirect benefits from the financing arrangements contemplated by this
Indenture and that the waiver set forth in this Section 12.04 will be knowingly
made in contemplation of such benefits.

     SECTION 12.05. Immediate Payment.

     Each Subsidiary Guarantor will agree to make immediate payment to the
Trustee on behalf of the Guaranteed Parties of all Guaranteed Obligations owing
or payable to the respective Guaranteed Parties upon receipt of a demand for
payment therefor by the Trustee to such Subsidiary Guarantor in writing.

     SECTION 12.06. No Set-off.

     Each payment to be made by any Subsidiary Guarantor hereunder in respect of
the Guaranteed Obligations shall be payable in the currency or currencies in
which such Guaranteed Obligations are denominated, and shall be made without
set-off, counterclaim, reduction or diminution of any kind or nature.

     SECTION 12.07. Obligations Absolute.

     The obligations of any Subsidiary Guarantor hereunder shall be absolute and
unconditional and any monies or amounts expressed to be owing or payable by the
Subsidiary Guarantor hereunder which may not be recoverable from the Subsidiary
Guarantor on the basis of a guarantee shall be recoverable from the Subsidiary
Guarantor as a primary obligor and principal debtor in respect thereof.

     SECTION 12.08. Obligations Continuing.

     The obligations of any Subsidiary Guarantor hereunder shall be continuing
and shall remain in full force and effect until all the Guaranteed Obligations
have been paid and satisfied in full.

     SECTION 12.09. Obligations Not Reduced.

     The obligations of any Subsidiary Guarantor hereunder shall not be
satisfied, reduced or discharged by any intermediate payment or satisfaction of
the whole or any part of the principal, interest, fees and other monies or
amounts which may at any time be or become owing or payable under or by virtue
of or otherwise in connection with the Senior Notes or this Indenture.

     SECTION 12.10. Obligations Reinstated.

     The obligations of any Subsidiary Guarantor hereunder shall continue to be
effective or shall be reinstated, as the case may be, if at any time any payment
which would otherwise have reduced the obligations of the Subsidiary Guarantor
hereunder (whether such payment shall have been made by or on behalf of the
Company or by or on behalf of the Subsidiary Guarantor) is rescinded or
reclaimed from any of the Guaranteed

                                      118

Parties upon the insolvency, bankruptcy, liquidation or reorganization of the
Company or the Subsidiary Guarantor or otherwise, all as though such payment had
not been made. If demand for, or acceleration of the time for, payment by the
Company is stayed upon the insolvency, bankruptcy, liquidation or reorganization
of the Company, all such indebtedness otherwise subject to demand for payment or
acceleration shall nonetheless be payable by the Subsidiary Guarantor as
provided herein.

     SECTION 12.11. Obligations Not Affected.

     The obligations of any Subsidiary Guarantor hereunder shall not be
affected, impaired or diminished in any way by any act, omission, matter or
thing whatsoever, occurring before, upon or after any demand for payment
hereunder (and whether or not known or consented to by the Subsidiary Guarantor
or any of the Guaranteed Parties) which, but for this provision, might
constitute a whole or partial defense to a claim against the Subsidiary
Guarantor hereunder or might operate to release or otherwise exonerate any
Subsidiary Guarantor from any of its obligations hereunder or otherwise affect
such obligations, whether occasioned by default of any of the Guaranteed Parties
or otherwise, including, without limitation:

         (a) any limitation of status or power, disability, incapacity or other
     circumstance relating to the Company or any other person, including any
     insolvency, bankruptcy, liquidation, reorganization, readjustment,
     composition, dissolution, winding-up or other proceeding involving or
     affecting the Company or any other person;

         (b) any irregularity, defect, unenforceability or invalidity in respect
     of any indebtedness or other obligation of the Company or any other person
     under this Indenture, the Senior Notes or any other document or instrument;

         (c) any failure of the Company, whether or not without fault on its
     part, to perform or comply with any of the provisions of this Indenture or
     the Senior Notes, or to give notice thereof to the Subsidiary Guarantor;

         (d) the taking or enforcing or exercising or the refusal or neglect to
     take or enforce or exercise any right or remedy from or against the Company
     or any other person or their respective assets or the release or discharge
     of any such right or remedy;

         (e) the granting of time, renewals, extensions, compromises,
     concessions, waivers, releases, discharges and other indulgences to the
     Company or any other person;

         (f) any change in the time, manner or place of payment of, or in any
     other term of, any of the Senior Notes, or any other amendment, variation,
     supplement, replacement or waiver of, or any consent to departure from, any
     of the Senior Notes or this Indenture, including, without limitation, any
     increase or decrease in the principal amount of or premium, if any, or
     interest on any of the Senior Notes;

                                      119

         (g) any change in the ownership, control, name, objects, businesses,
     assets, capital structure or constitution of the Company or the Subsidiary
     Guarantor;

         (h) any merger or amalgamation of the Company or the Subsidiary
     Guarantor with any person or persons;

         (i) the occurrence of any change in the laws, rules, regulations or
     ordinances of any jurisdiction by any present or future action of any
     governmental authority or court amending, varying, reducing or otherwise
     affecting, or purporting to amend, vary, reduce or otherwise affect, any of
     the Guaranteed Obligations or the obligations of the Subsidiary Guarantor
     under its Guarantee; and

         (j) any other circumstance (other than by complete, irrevocable
     payment) that might otherwise constitute a legal or equitable discharge or
     defense of the Company under this Indenture or the Senior Notes or of the
     Subsidiary Guarantor in respect of its Guarantee hereunder.

     SECTION 12.12. Waiver.

     Without in any way limiting the provisions of Section 12.01 hereof, each
Subsidiary Guarantor waives notice of acceptance hereof, notice of any liability
of the Subsidiary Guarantor hereunder, notice or proof of reliance by the
Guaranteed Parties upon the obligations of any Subsidiary Guarantor hereunder,
and diligence, presentment, demand for payment on the Company, protest, notice
of dishonor or non-payment of any of the Guaranteed Obligations, or other notice
or formalities to the Company or the Subsidiary Guarantor of any kind
whatsoever. Each Subsidiary Guarantor will waive all benefits set forth in
Articles 480 (second paragraph), 481 and 482 of the Argentine Commercial Code as
well as any rights and powers contemplated by Articles 1990, 1994, 2012, 2015,
2017, 2018, 2020, 2021 (except the right to oppose payment), 2022, 2023, 2024,
2025, 2026, 2028, 2029, 2043, 2044, 2045, 2046, 2047, 2049 (except in the case
of express prior written waiver issued by the Trustee and authorized in
accordance with this Indenture), and 2050 of the Argentine Civil Code, to the
extent any such rights of defenses would otherwise become applicable or
available to the Subsidiary Guarantor. The Subsidiary Guarantor will acknowledge
that it will receive direct and indirect benefits from the issuance of the
Senior Notes pursuant to this Indenture and that the waivers set forth in this
Section 12.13 will be knowingly made in contemplation of such benefit.

     SECTION 12.13. Dealing with the Company and Others.

     The Guaranteed Parties, without releasing, discharging, limiting or
otherwise affecting in whole or in part the obligations and liabilities of the
Subsidiary Guarantor hereunder and without the consent of or notice to any
Subsidiary Guarantor, may

                                      120

         (a) grant time, renewals, extensions, compromises, concessions,
     waivers, releases, discharges and other indulgences to the Company or any
     other person;

         (b) take or abstain from taking security or collateral from the Company
     or from perfecting security or collateral of the Company;

         (c) release, discharge, compromise, realize, enforce or otherwise deal
     with or do any act or thing in respect of (with or without consideration)
     any and all collateral, mortgages or other security given by the Company or
     any third party with respect to the obligations or matters contemplated by
     this Indenture or the Senior Notes;

         (d) accept compromises or arrangements from the Company;

         (e) apply all monies at any time received from the Company or from any
     security upon such part of the Guaranteed Obligations as the Guaranteed
     Parties may see fit or change any such application in whole or in part from
     time to time as the Guaranteed Parties may see fit; and

         (f) otherwise deal with, or waive or modify their right to deal with,
     the Company and all other Persons and any security as the Guaranteed
     Parties or the Trustee may see fit.

     SECTION 12.14. Default and Enforcement.

     If any Subsidiary Guarantor fails to pay in accordance with Section 12.05
hereof, the Trustee may proceed in its name as trustee hereunder in the
enforcement of the Guarantee of such Subsidiary Guarantor and such Subsidiary
Guarantor's obligations thereunder and hereunder by any remedy provided by law,
whether by legal proceedings or otherwise, and to recover from such Subsidiary
Guarantor the Guaranteed Obligations.

     SECTION 12.15. Costs and Expenses.

     Each Subsidiary Guarantor shall pay on demand by the Trustee any and all
costs, fees and expenses (including, without limitation, legal fees on a
solicitor and client basis) incurred by the Trustee, its agents, advisors and
counsel or any of the Guaranteed Parties in enforcing any of their rights under
the Guarantee issued by such Subsidiary Guarantor.

     SECTION 12.16. No Waiver; Cumulative Remedies.

     No failure to exercise and no delay in exercising, on the part of the
Trustee or the other Guaranteed Parties, any right, remedy, power or privilege
hereunder or under the Indenture or the Senior Notes, shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder or under this Indenture or the Senior Notes preclude any
other or further exercise thereof or the exercise of any other right, remedy,
power or privilege. The rights, remedies, powers and privileges in the Guarantee
and under this Indenture, the Senior Notes and any other

                                      121

document or instrument between the Subsidiary Guarantor and/or the Company and
the Trustee are cumulative and not exclusive of any rights, remedies, powers and
privilege provided by law.

     SECTION 12.17. Representation and Warranty of the Subsidiary Guarantor.

     Each Subsidiary Guarantor will represent and warrant that all acts,
conditions and things required to be done and performed and to have happened
precedent to the creation and issuance of its Guarantee, to constitute the same
valid, binding and legal obligation of each Subsidiary Guarantor, enforceable
against such Subsidiary Guarantor, its successors and assigns in accordance with
its terms, will have been done and performed and have happened in compliance
with all applicable laws. The obligation of each Subsidiary Guarantor under its
Guarantee shall constitute a direct, general, irrevocable, unsecured and
unsubordinated obligations of such Subsidiary Guarantor.

     SECTION 12.18. Special Waiver.

     To the extent that any Subsidiary Guarantor may be entitled to the benefit
of any provision of law requiring the Trustee or any Holder of the Senior Notes,
in any suit, action or proceeding brought in a court of Argentina or other
jurisdiction arising out of or in connection with any of this Indenture or the
Senior Notes, to post security for litigation costs or otherwise post a
performance bond or guaranty ("CAUTIO JUDICATUM SOLVI" or "EXCEPCION DE
ARRAIGO"), or to take any similar action, the Subsidiary Guarantor will waive
such benefit, in each case to the fullest extent permitted under the laws of
Argentina or, as the case may be, such other jurisdiction.

     SECTION 12.19. Severability.

     Any provision of this Article Twelve which is prohibited or unenforceable
in any jurisdiction shall not invalidate the remaining provisions and any such
prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction unless its removal
would substantially defeat the basic intent, spirit and purpose of this
Indenture and this Article Twelve.

     SECTION 12.20. Successors and Assigns.

     Any Guarantee shall be binding upon and inure to the benefit of any
Subsidiary Guarantor and the Trustee and the other Guaranteed Parties and their
respective successors and permitted assigns, except that any Subsidiary
Guarantor may assign any of its obligations hereunder or thereunder.

     SECTION 12.21. General Limitation on Guarantee Obligations.

     In any action or proceeding involving any state corporate law, or any state
or Federal bankruptcy, insolvency, reorganization or other law affecting the
rights of creditors generally or similar laws applicable in Argentina, if the
obligations of any Subsidiary Guarantor under Section 12.01 would otherwise be
held or determined to be void, voidable, invalid or unenforceable, or
subordinated to the claims of any other

                                      122

creditors, on account of the amount of its liability under Section 12.01, then,
notwithstanding any other provision to the contrary, the amount of such
liability shall, without any further action by such Subsidiary Guarantor, any
Holder of Senior Notes, the Trustee or any other Person, be automatically
limited and reduced to the highest amount that is valid and enforceable and not
subordinated to the claims of other creditors as determined in such action or
proceeding so as not to constitute a fraudulent transfer under any such
applicable law.

                                   ARTICLE 13
                       DEFEASANCE AND COVENANT DEFEASANCE

     SECTION 13.01. Company's Option to Effect Defeasance or Covenant
Defeasance.

     The Company may, at its option by Board Resolution, at any time elect to
apply either Section 13.02 or Section 13.03 to all Outstanding Senior Notes upon
compliance with the conditions set forth below in this Article Thirteen.

     SECTION 13.02. Defeasance and Discharge.

     Upon the Company's exercise under Section 13.01 of its option to apply this
Section 13.02, the Company and any Subsidiary Guarantor, if any, shall be deemed
to have been discharged from its obligations with respect to all Outstanding
Senior Notes on the date the conditions set forth in Section 13.04 are satisfied
(hereinafter, "DEFEASANCE"). For this purpose, such defeasance means that the
Company and any such Subsidiary Guarantor will be deemed to have paid and
discharged the entire Indebtedness represented by the Outstanding Senior Notes,
which shall thereafter be deemed to be "OUTSTANDING" only for the purposes of
Section 13.05 and the other Sections of this Indenture referred to in clauses
(A) and (B) below, and to have satisfied all its other obligations under such
Senior Notes, the Subsidiary Guarantees and this Indenture insofar as such
Senior Notes are concerned (and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging the same), except for the
following which shall survive until otherwise terminated or discharged
hereunder: (A) the rights of Holders of Outstanding Senior Notes to receive,
solely from the trust fund described in Section 13.04 and as more fully set
forth in such Section, payments in respect of the principal of, premium, if any,
and interest on such Senior Notes when such payments are due on the Stated
Maturity (or upon redemption, if applicable), (B) the Company's obligations with
respect to such Senior Notes under Sections 1.12, 3.04, 3.05, 3.06, 3.07, 3.11,
3.12, 5.15, 6.08(e), 10.02, 10.03, 10.08 (but only to the extent such section is
applicable to Default of an obligation under this Indenture not defeased) and
10.09 (but only to the extent of Additional Amounts other than Additional
Amounts payable under then applicable law; for the purposes of applying Section
10.09 after defeasance, if the Trustee is required by law or by the
administration or interpretation thereof to withhold or deduct any amount for or
on account of Taxes from any payment made from the trust fund described in
Section 13.04 under or with respect to the Senior Notes, such payment

                                      123

shall be deemed to have been made by the Company and the Company shall be deemed
to have been so required to deduct or withhold), (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article Thirteen.
Subject to compliance with this Article Thirteen, the Company may exercise its
option under this Section 13.02 notwithstanding the prior exercise of its option
under Section 13.03 with respect to the Senior Notes.

     SECTION 13.03. Covenant Defeasance.

     Upon the Company's exercise under Section 13.01 of its option to apply this
Section 13.03, the Company and any Subsidiary Guarantor, if any, shall be
released from their respective obligations under any covenant contained in
Section 8.01(a)(iii) and (iv), Section 8.03 and Sections 10.10 through 10.20
with respect to the Outstanding Senior Notes on and after the date the
conditions set forth below are satisfied (hereinafter, "COVENANT DEFEASANCE"),
and the Senior Notes shall thereafter be deemed not to be "Outstanding" for the
purposes of any direction, waiver, consent or declaration or Act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "OUTSTANDING" for all other purposes hereunder. For this
purpose, such covenant defeasance means that, with respect to the Outstanding
Senior Notes, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Sections 5.01(iii)
and (iv), but, except as specified above, the remainder of this Indenture and
such Senior Notes shall be unaffected thereby.

     SECTION 13.04. Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to application of either Section
13.02 or Section 13.03 to the Outstanding Senior Notes:

     (a) The Company shall irrevocably have deposited or caused to be deposited
with the Trustee (or another trustee satisfying the requirements of Section 6.07
who shall agree to comply with the provisions of this Article Thirteen
applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Senior Notes, (A) cash in US Dollars in
an amount, (B) U.S. Government Obligations which through the scheduled payment
of principal and interest in respect thereof in accordance with their terms will
provide, not later than one day before the due date of any payment, money in an
amount, or (C) a combination thereof, as will be sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or other qualifying trustee) to pay
and discharge the principal of (and premium, if any), interest, Liquidated
Damages and all Additional Amounts payable under then applicable law on the
Outstanding Senior Notes on the Stated Maturity (or Redemption Date, if
applicable) of such principal (and premium, if any) or installment of

                                      124

interest; provided that the Trustee shall have been irrevocably instructed to
apply such money or the proceeds of such U.S. Government Obligations to said
payments with respect to the Senior Notes. Before such a deposit, the Company
may give to the Trustee, in accordance with Section 11.03 hereof, a notice of
its election to redeem all of the Outstanding Senior Notes at a future date in
accordance with Article Eleven hereof, which notice shall be irrevocable. Such
irrevocable redemption notice, if given, shall be given effect in applying the
foregoing. For this purpose, "U.S. GOVERNMENT OBLIGATIONS" means securities that
are (x) direct obligations of the United States of America for the timely

paragraphs (j) and (k) of Section 5.01 hereof are concerned, at any time during
the period ending on the 91st day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until the
expiration of such period).

     (c) Such defeasance or covenant defeasance shall not result in a breach or

received from, or there has been published by, the Internal Revenue Service a
ruling, or (y) since the Original Issue Date, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such opinion shall confirm that, the Holders of the Outstanding Senior
Notes will not recognize income, gain or loss for federal income tax purposes as
a result of such defeasance and will be subject to federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such defeasance had not occurred.

     (e) In the case of an election under Section 13.03, the Company shall have
delivered to the Trustee an Opinion of Counsel to the effect that the Holders of
the Outstanding Senior Notes will not recognize income, gain or loss for federal
income tax

                                      125

purposes as a result of such covenant defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such covenant defeasance had not occurred.

     (f) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the defeasance under Section 13.02 or

     SECTION 13.05. Deposited Money and U.S. Government Obligations to Be Held
in Trust; Other Miscellaneous Provisions.

     Subject to the provisions of the last paragraph of Section 10.03, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee (or other qualifying trustee, collectively for purposes of this
Section 13.05, the "TRUSTEE") pursuant to Section 13.04 in respect of the
Outstanding Senior Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Senior Notes and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
such Senior Notes of all sums due and to become due thereon in respect of
principal (and premium, if any), interest, Liquidated Damages and Additional
Amounts payable under then applicable law, but such money need not be segregated
from other funds except to the extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Governmental Obligations
deposited pursuant to Section 13.04 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Senior Notes.

     Anything in this Article Thirteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 13.04 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent defeasance or covenant
defeasance, as applicable, in accordance with this Article.

     SECTION 13.06. Reinstatement.

     If the Trustee or any Paying Agent is unable to apply any money in
accordance with Section 13.05 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's and the Subsidiary Guarantor's, if any,
obligations under this Indenture and the Senior Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 13.02 or 13.03,
as the case may be, until such time as the Trustee or Paying Agent is permitted
to apply all such money in accordance with Section 13.05;

                                      126

provided, however, that if the Company makes any payment of principal of (or
premium, if any) or interest on any Senior Note following the reinstatement of
its obligations, the Company shall be subrogated to the rights of the Holders of
such Senior Notes to receive such payment from the money held by the Trustee or
Paying Agent.
