Initial Hedge Positions:

The Hedge Positions established by the Hedging Party during the Initial Hedging Period.

Initial Hedging Period:

The period from, and including, the Effective Date to, and including, the earliest of (a) the day on which the Hedging Party completes establishing Initial Hedge Positions in respect of the Maximum Number of Shares, (b) the Initial Hedging Period End Date and (c) the effective date of a Counterparty Election Notice in which Counterparty notifies [*] and the Calculation Agent that it wishes to end the Initial Hedging Period, provided that (x) such period shall be deemed to also extend to the later of: (i) the last day of any Restricted Period and (ii) the latest date of settlement and admission to trading of any Shares issued in respect of an exercise of Rights and (y) Counterparty may not deliver a Counterparty Election Notice under subparagraph (c) hereof during any Restricted Period.

In respect of Shares, the Hedging Party will use its reasonable efforts to establish its Initial Hedge Positions in such a way so the number of Shares in respect of which the Hedging Party establishes its Initial Hedge Positions in respect of each Exchange Business Day, excluding any Exchange Business Day falling within the Restricted Period, will be as close as reasonably practicable to the Target Daily Shares; provided, however, that in no event will the number of Shares in respect of which the Hedging Party establishes its Initial Hedge Positions in respect of an Exchange Business Day exceed (a) the 4 Week Target Daily Shares or (b) if there is a public announcement (as defined in Rule 165(f) under the Securities Act of 1933, as amended (the “Securities Act”)) of any Merger Transaction (such announcement, a “Public Announcement”), from the Notification of Public Announcement until the Notification of Completion of Merger Transaction Restricted Period (the “Merger Transaction Restricted Period”), the lesser of (i) the 4 Week Target Daily Shares and (ii) the average daily number of Shares in respect of which the Hedging Party has established its Initial Hedge Positions during the three full calendar months preceding the date of such Public Announcement, as determined by the Calculation Agent (the “Merger Target Daily Shares”). The price per Share at which the Hedging Party establishes its Initial Hedge Positions may not exceed the Maximum Share Reference Price. “Merger Transaction” means any merger, acquisition or similar transaction involving a recapitalisation of the Issuer as contemplated by Rule 10b-18(a)(13)(iv) under the Exchange Act. The Hedging Party’s obligations and restrictions with regard to the number of Shares in respect of which the Hedging Party establishes its Initial Hedge Positions in respect of an Exchange Business Day and the price at which such Initial Hedge Positions are established shall not apply with respect to any Initial Hedge Positions established as a result of the Hedging Party subscribing for all Deemed Shares.

Page 6 of 33

In respect of Rights, the Hedging Party will use its reasonable efforts to establish its Initial Hedge Positions in such a way so the number of Rights in respect of which the Hedging Party establishes its Initial Hedge Positions:

(a) during the Mandatory Period, will not exceed the Maximum Number of Mandatory Period Rights;

(b) during the Voluntary Period, (taking into account Purchased Rights and any Rights distributed to the Hedging Party by the Issuer during the Voluntary Period) will not exceed the Maximum Number of Voluntary Period Rights (it being understood that the Hedging Party shall not have breached its obligations under this clause (b) in the event that the number of Rights distributed to the Hedging Party by the Issuer during the Voluntary Period exceeds the Maximum Number of Voluntary Period Rights, in which case the number of Voluntary Period Purchased Rights shall be zero); and

(c) in each case, in respect of each Exchange Business Day during the relevant period shall be as close as reasonably practicable to the Target Daily Rights unless: (i) a Distress Event has occurred at any time on any such Exchange Business Day or (ii) in respect of the final two Exchange Business Days of the Mandatory Period and the Voluntary Period, respectively, the Hedging Party in its reasonable opinion considers that it would not be able, taking commercially reasonable efforts, to effectively exercise such Rights and subscribe for resulting Shares prior to the end of such relevant period, in which case the Initial Hedge Positions to be established on such Exchange Business Day shall be in an amount to be determined by the Hedging Party in its sole discretion which, for the avoidance of doubt, may be zero.

The price per Right at which the Hedging Party establishes its Initial Hedge Positions may not exceed the applicable Maximum Right Reference Price on such Exchange Business Day.

Except as set forth in clause (b) above, the Hedging Party’s obligations with regard to the number of Rights in respect of which the Hedging Party establishes its Initial Hedge Positions in respect of an Exchange Business Day and the price at which such Initial Hedge Positions are established shall not apply with respect to any Initial Hedge Positions established as a result of the distribution by the Issuer of any Rights to the Hedging Party during the Voluntary Period as a result of the Hedging Party exercising Rights acquired by it during the Mandatory Period.

Page 7 of 33

In respect of each Exchange Business Day during the Initial Hedging Period, the Calculation Agent shall notify Counterparty, by no later than 10:00 am New York City time on the immediately following Business Day, of (a) the number of Shares and the number of Purchased Rights in respect of which the Hedging Party established Initial Hedge Positions on such day and (b) the volume weighted average price per Share and the volume-weighted average price per Right, each converted into USD at the applicable Exchange Rate on such day, at which the Hedging Party established its Initial Hedge Positions on such day in each case in respect of such Exchange Business Day. The Calculation Agent shall notify Counterparty no later than 10:00 a.m., New York City time on the Business Day following the last day of the Initial Hedging Period of the occurrence of the last day of the Initial Hedging Period

Notwithstanding that the Target Daily Shares shall be zero during the Restricted Period, the Hedging Party shall be entitled to establish Initial Hedge Positions by being granted Rights, acquiring Purchased Rights and exercising Rights and subscribing for the Shares relating to those Rights.

Target Daily Rights:

(a) In respect of a Scheduled Trading Day during the Rights Acquisition Period, where the Rights Volume Threshold meets or exceeds the Share Volume Threshold, an amount equal to [*]% of the daily trading volume for the Rights on that day, or such other percentage (subject to a maximum of [*]%) as notified by Counterparty to [*] and the

Page 8 of 33

	Calculation Agent from time to time in a Counterparty Election Notice. The daily trading volume for the Rights on any Scheduled Trading Day shall be as determined by the Calculation Agent by reference to the relevant Bloomberg page (such page to be notified by the Calculation Agent to Counterparty and Hedging Party once available), or if such information is not available for whatever reason or is manifestly incorrect, as determined by the Calculation Agent acting in a commercially reasonable manner; and (b) in respect of a Scheduled Trading Day during the Rights Acquisition Period where the Rights Volume Threshold is less than the Share Volume Threshold, zero.

Distress Event:	On any Scheduled Trading Day during the Rights Acquisition Period, [*] determines, acting in a commercially reasonable manner, that the Rights are trading in a distressed manner.
Maximum Share Reference Price:	CLP [] (or such other price (being a number of CLP) as is notified by Counterparty to [] and the Calculation Agent from time to time in a Counterparty Election Notice).
Maximum Right Reference Price:	On any Scheduled Trading Day, an amount in CLP per Right calculated, in respect of the number of Rights required to subscribe for one Share during the Mandatory Period or the Voluntary Period, as applicable, as an amount equal to the Maximum Share Reference Price minus the subscription price of that Share, converted into CLP by reference to the Exchange Rate as at the immediately preceding Local Currency Business Day.

Valuation Disruption:	The definition of “Market Disruption Event” in Section 6.3(a) of the Equity Definitions is hereby amended by deleting the words “at any time during the one-hour period that ends at the relevant Valuation Time, Latest Exercise Time, Knock-in Valuation Time or Knock-out Valuation Time, as the case may be” and inserting the words “at any time on any Scheduled Trading Day during the Initial Hedging Period” after the word “material,” in the third line thereof. Section 6.3(d) of the Equity Definitions is hereby amended by deleting the remainder of the provision following the term “Scheduled Closing Time” in the fourth line thereof. Notwithstanding anything to the contrary in the Equity Definitions, if a Disrupted Day occurs in the Initial Hedging Period, the Calculation Agent may, in its good faith and commercially reasonable discretion, postpone the Initial Hedging Period End Date by the number of Disrupted Days, but not exceeding eight Scheduled Trading Days. In the event that the Hedging Party concludes, in its sole discretion, that it is advisable, based on the advice of counsel, with respect to any legal, regulatory or self-regulatory requirements or related policies and procedures (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by the Hedging Party), for it to refrain from or decrease any market activity on any Scheduled Trading Day or Scheduled Trading Days during the Initial Hedging Period, the Hedging Party may, by written notice to Counterparty, elect to deem that a Market Disruption Event has occurred and will be continuing on such Scheduled Trading Day or Scheduled Trading Days.

Daily Equity Notional Amount:	In respect of each Exchange Business Day, an amount equal to the sum of (i) the product of (a) the number of Shares in respect of which the Hedging Party has established Initial Hedge Positions on such day and (b) the volume weighted

FX Disruption:	An FX Disruption shall occur if any of the government of Chile or its agencies, instrumentalities or entities (including, without limitation, its banks), by means of any law, regulation, ruling, directive or interpretation, whether or not having the force of law, takes any action, which is in existence or has effect on the relevant day or any date thereafter through the related settlement date on which the related foreign exchange transaction would be expected to settle, as the case may be, which, legally or de facto, prevents, or has the effect of restricting or limiting, (i) the general availability of USD at an exchange spot rate equal to the Exchange Rate in any legal foreign exchange market in Chile in accordance with normal commercial practice, (ii) the ability to exchange CLP for USD or (iii) the transfer of or receipt of CLP or USD outside of Chile through customary legal channels.
