yet subordinating and postponing its rights until all Sellers receive full
payment, both as a result of pledge actions exercise and regarding the

5.2 Commercial pledge and prohibition to encumber and transfer of shares.

undertaken by Buyer by virtue of this contract, particularly concerning
payment of the price balance agreed upon under paragraph 3.2.2,
adjustments, regular interests, interest on arrears and judicial fees
thereof, if any, Buyer hereby grants a commercial pledge in favor of

the Code of Commerce, on all and every Shares as individualized under

accounting for 496,671,907 shares of Banco de Chile; and titles No.
1009498-04 accounting for 3,802,172 shares of SM Chile - Series A; No.
1056011-10 accounting for

1,422,465,232 shares of SM Chile - Series B; No. 38976-05 accounting for
21,159,587 shares of SM Chile - Series D; and No. 30044-06 accounting for

and capacity to receive them as a surety for all and every principal and
accessory obligations of Buyer stemming from this document, particularly
to secure price balance, adjustments and regular and on arrears interests,

Likewise, it is expressly placed on record that on this date, the
authenticating Notary Public has notified SM Chile and Banco de Chile
general managers on the commercial pledge granted herein and has further

5.2.3 As a result of Shareholder Agreement Contracts by virtue of which Xxxxx
has granted a commercial pledge in favor of the other member groups of
Banco de Chile's major shareholders agreement, on the shares sold by every
of these shareholders, to secure all Buyer's obligations and particularly
the payment of the relevant price balances and accessory payments and,
taking into consideration that in Sellers' interest, an adequate surety
should be made available so as to secure faithful and timely payment of
all and every price balances owed by Buyer, the parties hereby agree that
in the event all the shares pledged by Buyer in favor of the shareholder
groups mentioned hereinabove and of Sellers as a consequence of this

at any time, for a percentage lower than 35% of all the political and
voting rights of Banco de Chile, or a percentage below the number of
shares it holds at the company resulting from any merger or arising out of
a capital increase of Banco de Chile, the amount equivalent to the current
35% of all the political and voting rights of Banco de Chile, Buyer shall
supplement the relevant surety at Sellers' request so that a debt - surety
ratio amounting to 1:1 is kept. Consequently, a commercial pledge shall be
granted on a prorated and simultaneous basis concerning this Purchase
Contract and each and every Shareholders agreement contracts, on other
shares of corporations based upon their market value, so that the
outstanding balance of the debt resulting from the price balance is always
secured by a stock pledge whereby the market value of the shares subject
matter of this stock pledge

is not lower than the total outstanding price balance. Pledged shares
"Market value" shall be construed as the average weighed stock exchange
transaction value thereof over the last 60-day period. As to the shares
required to supplement this surety, they should preferably correspond to
SM Chile and/or Banco de Chile, or to other public stock corporations, in

relevant owners, however, the following exceptions shall be applicable: a)
Whenever the price balance and/or the interests thereof as provided under
clause three in this instrument and secured by means of the pledge fall
due and, regardless of the collection procedures related to price balance
and/or its interests that pledgees might undertake, dividends shall belong
to Sellers. Consequently, Sellers shall charge and collect them directly
from issuer company and then credit and allot them as per general norms;
and b) Should all the shares pledged by Buyer in favor of the shareholder
groups individualized under paragraph 2.3 and in favor of Sellers by
virtue of this contract and shareholders agreement contracts account - at
any time - for a percentage lower than 35% of all the political and voting
rights of Banco de Chile, or a percentage below the number of shares it
holds at the company resulting from any merger or arising out of a capital
increase of Banco de Chile, the amount equivalent to the current 35% of
all the political and voting rights of Banco de Chile, and should the debt
- surety ratio be lower than 1:1, then dividends shall only be collected
by Buyer if duly authorized by Seller. Should no authorization be
available, the relevant dividends shall belong to Sellers, who shall be
entitled to charge and collect them directly from issuer company, in which
case, they shall take a renewable 30-day term deposit at Banco de Chile
until the debt - surety ratio regains the 1:1 level. Furthermore, should
this 1:1 debt - surety ratio fails to be regained within the
aforementioned 60-day term as of requirement to Buyer from Sellers, the
latter shall be entitled to and shall collect, credit and allocate the
amount of the aforesaid deposit to the price balance, according to general
rules of business. Should the surety be supplemented within the term
mentioned hereinabove, the term deposit shall be rendered to Buyer.

5.2.5 For the purposes of charging and collecting Shares dividends, in the cases
and under the terms and conditions provided under items a) and b) in
paragraph 5.2.4

hereinabove, Buyer hereby grants a special and irrevocable power of
attorney to Sociedad de Inversiones y Xxxxxx MegeveLimitada and Sociedad
de Inversiones y Xxxxxx Liguria Limitada, which shall be entitled to
proceed by means of any of their representatives thereof, entitling them
to charge, collect and perceive the dividends of issuer company shares, as
well as to credit and allocate them to the price balance owed by Xxxxx, if
applicable. This power of attorney has an irrevocable character, as per
the terms and conditions provided under article 241 in the Code of
Commerce and is granted for the benefit of the grantor, consequently, it
shall remain in full force for the entire period along which the pledge
referred to under paragraph 5.2 is effective. Furthermore, this power is
totally free, as a result of which, the representative shall not receive
any compensations whatsoever when acting in such capacity. Should Buyer
revoke the power granted in the paragraph hereinabove or should it be
terminated for any other causes attributable to Buyer, Sellers shall be
then entitled to exercise, either individually or on a joint basis, all
those rights and actions granted thereto so as to claim compensation for
any loss resulting from the aforementioned situation and affecting
Sellers. Neither the granting of this power, nor the termination thereof
shall terminate or restrict the pledge subject matter of this document in
any manner whatsoever, which shall remain in full force for as long as any
portion of the secured price balance remains unpaid, all of which,
notwithstanding what provided under article 2.401 in the Civil Code.

5.2.6 Should partial advance payments of the price balance take place, either
voluntary or mandatory, Sellers shall release the pledge and prohibition
to encumber and transfer on a pro rata basis with the advance payment
amount, unless the situation specified under paragraph 5.2.3 occurs.

5.3 Inversiones Hidrosur Limitada's Guarantee.

5.3.1 Hidrosur, hereby duly represented by Xx. Xxxxxxxxx Xxxxxx Xxxxx, hereby
grants a joint and several guarantee in favor of Sellers, who in turn
hereby accept this guarantee, for the purposes of securing the advance
payment obligation undertaken by Buyer by virtue of clause four of this
contract, a surety that shall be limited to the net sales value of ENTEL
Shares to an unrelated third party.

5.3.2 Hidrosur's joint and several guarantee shall be enforced in the event
that, once ENTEL Shares have been sold to an unrelated third party, Buyer
fails to pay Sellers an amount equivalent to the entire net sales price of
said shares.

Accordingly, Seller shall be entitled to request payment of the price
balance on an equally advance basis as per the provision under paragraph
7.3 hereinbelow.

5.3.3 Should Hidrosur sell or transfer ENTEL Shares in any manner whatsoever to
a related party or company, on a joint basis with transfer, it shall
undertake the obligation of becoming joint and several guarantor under the
same terms and conditions as specified hereunder. Failure to do so under
the aforementioned terms and conditions shall be construed as transfer
being done to an unrelated third party and, hence, the advance payment
obligation provided under clause four hereinabove shall be executed.

SIX: OTHER OBLIGATIONS OF BUYER AND JOINT AND SEVERAL DEBTOR

As long as the price balance payment remains outstanding, Buyer and Joint and
Several Debtor undertake before Sellers strict compliance of the obligations
specified hereinbelow:

6.1 Providing Sellers' representative, as appointed under clause sixteen
herein, hereinafter designated the "Representative" with quarterly
consolidated financial statements as per the FECU ("Ficha Estadistica
Consolidada Uniforme") format, within a 30-consecutive days term as of the
end of the relevant quarter in the case of Buyer and within the same term
established for such purposes by the Superintendence of Securities and
Insurance in the case of Joint and Several Debtor. On the other hand,
Buyer and joint and several debtor shall provide Representative with their
general balance sheet and consolidated financial statements on December 31
every year, including their corresponding comments. The aforementioned
documents shall be duly audited and shall encompass the comments of their
external auditors, all of which shall be made available within a 120-day
term as of the end of the corresponding fiscal year.

6.2 Keeping an individual indebtedness level as part of which the Financial
Debt/Total Capitalization ratio shall not exceed 0.45 times. For the
purposes of calculating this ratio, Financial Debt shall be understood as
the addition of lots 21,010; 21,015; 21,020; 21,025; 21,030; 21,060;
21,075; 22,010; 22,020; 22,030; 22,040 & 22,045 of each individual
debtor's FECU. In turn, Total Capitalization shall be understood as the
addition of individual Net Worth and Financial Indebtedness.

6.3 At all moments, keeping a minimum individual net worth amounting to UF 33
million.

6.4 By the end of every fiscal quarter, keeping a consolidated indebtedness
level

whereby the Financial Debt/Total Capitalization ratio does not exceed 0.6
times. To calculate this ratio, Financial Debt shall be understood as the
addition of lots 21,010; 21,015; 21,020; 21,025; 21,030; 21,060; 21,075;
22,010; 22,020; 22,030; 22,040 & 22,045 of debtor's consolidated FECU,
plus the credit resulting from the price balance arising from this
Purchase Contract, unless such credit were included in previous lots. In
turn, Total Capitalization shall be construed as the addition of
consolidated Net Worth and individual Financial Indebtedness, plus
Minority Interest. Should Quinenco S.A. be forced to consolidate its
financial statements - consolidated FECU - with Banks or Financial
Institutions as per the definition provided on that regard under articles
40 and 112, respectively in the General Bank Law (Decree with the Force of
a Law No. 3.997) and/or with SM Chile or the Company managing the
subordinated debt of Banco de Chile S.A. (SAOS), calculation of the
aforementioned ratio shall not encompass any liability or obligation made
part of the consolidated FECU originating in a Bank or Financial
Institution and/or SM Chile and SAOS, with which the Joint and several
Debtor is forced to undertake consolidation. Failure to comply with this
obligation shall not result in a right to require advance payment of the
credit subject matter of this document, but shall prevent Buyer and Joint
and Several Debtor, from getting into further indebtedness, acquiring
shares issued thereby, distributing dividends in excess of the amount
provided under the dividend policy in force during such fiscal year and
from carrying out further investments with other companies as long as
failure to comply remained by the end of the following fiscal quarter (two
consecutive FECU).

6.5 Obtaining from Sellers their prior authorization in writing, should Buyer
and/or Joint and Several Debtor intend to merge, in any manner whatsoever,
divide or dissolve, an authorization that shall not be denied without due
justification, in which case Buyer and Joint and Several Debtor shall
resort to an arbitrator.

6.6 Obtaining the subordination of all the credits corresponding to parties
related to the entrepreneurial group to which Buyer and Joint and Several
Debtor belong, so that the credit accounting for the price balance as
specified under paragraph 3.2.2 hereinabove, the adjustments, regular
interests, interest on arrears and costs thereof, if any, is billed and
paid on a preferred basis to any of such related credits. The obligations
referred to under paragraphs 6.2, 6.3, 6.4 hereinabove shall only be
applicable to Joint and Several Debtor.

SEVEN: CAUSES FOR ACCELERATION

Should any of the causes for credit acceleration related to Shares' sales price
balance and term expiry specified hereinbelow take place, Sellers shall be
entitled to request, at their sole discretion, advanced payment of the entire
credit and, hence, the relevant obligation shall be deemed as due:

7.1 Should Buyer fail to pay any of the biannual interest installments
provided under paragraph 3.3 hereinabove accruing from the price balance.

7.2 Should Buyer breach the obligation of not encumbering or transferring all
or part of the Shares being pledged herein and/or the shares used for
supplementing the surety in case the 1:1 debt - surety ratio be reduced of
fail to furnish a further surety on a timely and due basis so that the
debt - surety ratio is regained.

7.3 Should Buyer or Hidrosur fail to pay Sellers an amount equal to the total
net sales price of ENTEL Shares in advance as per the terms, conditions,
manner and timeframe provided under paragraph 4.2 hereinabove, concerning
paragraphs 5.3.2 and 5.3.3 herein.

7.4 Should Buyer, Joint and Several Debtor and/or Hidrosur file for bankruptcy
or take the steps for a judicial or extrajudicial settlement.

7.5 Should, concerning Buyer, Joint and Several Debtor and/or Hidrosur, a
legal action be filed for judicial collection purposes based upon the
executive procedure, the amount of which is in excess of 5% of the total
net worth of the relevant company and should this company fail to
challenge the origin and/or truthfulness of such claim for collection or
the filing for bankruptcy, by means of written and supported background
before the relevant courts of justice, within the corresponding legal
timeframe for challenging purposes.

7.6 Should the entrepreneurial group known as Grupo Xxxxxx, current major
stockholder of Buyer's, Joint and Several Debtor's and Hidrosur's loose
control of Buyer or Banco de Chile or the exclusive control of the Joint
and Several Debtor or Hidrosur for any reason whatsoever that is either
attributable to such entrepreneurial group or not, without prior
authorization in writing from Sellers.

7.7 Should, as per the Bond Issuance Contract subscribed by Quinenco S.A. and
Banco Xxxx by means of a public deed granted before Santiago Notary Public
Xx. Xxxxx Xxxx Xxxxx on May 9, 2000, modified by means of a public deed
dated June 9, 2000, granted before the same Notary Public, advance payment
of such bonds

be requested as a result of any cause whatsoever.

7.8 Should Buyer or Joint and Several Debtor fail to comply with any of the
obligations provided under clause six hereinabove and fail to overcome
such breach within the 90 days following such occurrence, unless such
situation results from a cause attributable to Buyer or Joint and Several
Debtor, in which case the aforementioned term shall be reduced to 60 days.
Whenever Sellers exercise the right to accelerate payment of the price
balance, according to what agreed in this clause, they shall be entitled
to collect and perceive the interest on arrears referred to under
paragraph 3.4 herein, as per the terms and conditions specified herein.

Definitions

P = principal owed in UF as of advance payment date

i = price balance interest (8.5 per year, based on a 360-day year)

ip = advance payment interest (7.4 per year, based on a 360-day year)

q = P portion paid on an advanced basis

z = number of days elapsed as of last payment of interests

ID = accrued and unpaid interests until advance payment date corresponding to
the principal portion paid on an advanced basis

y = number of days elapsed from advance payment date until day 720

CP = advance payment penalty

CT = total amount paid expressed in UF

P' = new principal owed in UF

Formulas

ID = P x q [(1 + i)(z/360) - 1]

CP = P x q (1 + i)(y/360) - (P x q)
--------------------
(1 + ip)(y/360)

CT = P x q + ID + CP (should advance payment occurs 18 months prior to Promise
to sell)

CT = P x q + ID (should advance payment occurs 18 months after Promise to sell)

P' = P x (1 - q)

[Signatures illegible]

EXAMPLE:

Should UF 100,000 be paid in advance on day 60 of the contract and P = UF
250,000

Then q = 100,000 0.4
-------
250,000

ID = 250,000 x 0.4 x (1.085)(60/360) - 100,000

ID = UF 1,369

CP = 100,000 x (1.085)(660/360) - 100,000
------------------------
(1.074)(660/36)

CP = UF 1.886

CT = 100,000 + 1,369 + 1,886

CT = UF 103,255

P' = 250,000 x (1 - 0.4)

P' = 150,000
