GROUP HIGHLIGHTS - FIRST QUARTER 2005 AND SUBSEQUENT EVENTS

Quinenco

At the General Ordinary Shareholders' Meeting held on April 28, 2005,
shareholders approved a dividend distribution corresponding to 2004 net income
of Ch$12.97685 per share, payable to shareholders registered with the company as
of May 5, 2005. The total amount of the dividend is Ch$14,012 million,
equivalent to 60% of 2004 net income. At the same meeting, the entire Board of
Directors was reelected. Immediately following the General Ordinary
Shareholders' Meeting, an Extraordinary Board of Directors' meeting was held,
and Guillermo Luksic Craig and Andronico Luksic Craig were elected Chairman and
Vice-Chairman, respectively.

Almacenes Paris

In October 2004, Quinenco, through its wholly owned subsidiary, Inversiones Rio
Azul S.A., acquired an 11.41% interest in Almacenes Paris through the purchase
of 68,489,407 shares at Ch$514 pesos per share for a total of Ch$35,398 million
(historic pesos).

On March 22, 2005, Quinenco sold 18,718,155 shares of Almacenes Paris for Ch$960
per share (equivalent to 27.33% of its total shareholding) to Cencosud as part
of the tender offer launched by them. In connection with the sale of the Paris
shares, cash proceeds amounted to Ch$17,969 million, resulting in a gain on sale
of Ch$8,361 million for the period ended March 31, 2005.

The remaining 49,771,252 shares of Almacenes Paris were exchanged for 41,926,756
shares of Cencosud, in accordance with the terms of the tender offer. Shares
were valued on the March 22nd exchange at Ch$38,153 million. The exchange of
shares generated a one-time gain of Ch$12,604 million for the period ended March
31, 2005.

CCU

On March 12, 2005, an association between Pisconor, a wholly owned subsidiary of
CCU dedicated to the commercialization of pisco products, and Control, one of
the leading pisco producers in Chile, was approved. As a result, Pisconor and a
subsidiary of Control formed Compania Pisquera de Chile S.A. in mid-March. This
new company, controlled 80% by Pisconor, has an estimated 50.1% share of the
Chilean pisco market, according to the last AC Nielsen measurement.

Banco de Chile

On March 24, 2005, Banco de Chile's Board of Directors agreed to initiate the
sale of 1,701,994,590 shares (equivalent to 2.5% of total shares) of stock that
it had bought in 2004 according to articles 27 and 27D of the Chilean Companies
Law No. 18,046.

On January 21, 2005, Banco de Chile announced that the Office of the Comptroller
of the Currency (OCC) was conducting a targeted examination of its New York
branch to determine its compliance with the US Bank Secrecy Act and anti-money
laundering requirements. Simultaneously, the Federal Reserve Bank of Atlanta is
conducting a similar review of the Miami branch. The bank has reported that
these investigations are likely to result in supervisory actions, although the
nature and extent of such actions cannot be determined at this time.

Madeco

On April 4, 2005, Madeco announced that it had reached an agreement with Corning
International Corporation regarding the Brazilian joint venture subsidiary,
Optel Ltda. Corning agreed to sell Madeco its 50% share in Optel for R$1 (one
Brazilian Real). On the same date, Madeco announced that it had reached an
agreement with two of Optel's principal creditors to forgive US$5.3 million of a
US$7.3 million indebtedness (the difference was paid to the creditors). Optel
Ltda. is an optical fiber cable producer with installations in Brazil and
Argentina.

(US$14.7 million) in the first quarter of 2004. 1Q 2005 income (at the Quinenco
holding company level) included a non-recurring gain on the sale and exchange of

The net income contribution from operating companies reached Ch$21,910 million
(US$37.4 million), up by 10.9% compared to the same quarter in 2004. The
increase was attributable to higher results from all of Quinenco main operating
companies which benefited from strong growth under the favorable economic
conditions seen during the first quarter.

Earnings per ordinary share amounted to Ch$26.97 (US$0.05) and earnings per ADR,
Ch$269.66 (US$0.46).

Revenues - 1Q 2005

Consolidated revenues for the first quarter of 2005 were Ch$100,234 million
(US$171.1 million), up by 10.1% from the Ch$91,079 million (US$155.4 million)
reported in the first quarter of 2004, explained by a 14.9% increase in Madeco's
sales as a result of sustained demand for copper rod and copper and aluminum
cables in its main markets.

Consolidated sales can be broken down as follows: Madeco (86.5%), Telefonica del
Sur (12.9%) and others (0.6%).

Operating Income - 1Q 2005

Operating income for the first quarter of 2005 was Ch$7,557 million (US$12.9
million), up by 10.9% from the Ch$6,814 million (US$11.6 million) reported in
the first quarter of 2004. The sharp increase in consolidated operating income
was attributable to Madeco's operations, which benefited from the higher sales
level and reductions in SG&A expenses in the wire and cable business unit.

Quinenco reported non-operating income of Ch$29,257 million (US$49.9 million) in
the first quarter of 2005, compared to non-operating income of Ch$4,618 million
(US$7.9 million) in the same quarter of 2004. The variation between the two
periods is mostly explained by an increase of Ch$22,325 million (US$38.1
million) in other non-operating income as a result of the sale and exchange of
Almacenes Paris shares in March 2005. The main items included in non-operating
results are discussed below:

Proportionate share of net income of equity method investments (net)

Quinenco's proportionate share of net income from equity method investments
(net), which includes the results from Banco de Chile and CCU, Quinenco's most
significant investments, reached Ch$19,130 million (US$32.6 million), compared
to Ch$16,960 million (US$28.9 million) in 1Q 2004, an increase of 12.8%. The
increase corresponded to growth in the proportionate share of net income from
Banco de Chile (+8.4%), CCU (+14.2%) and Entel (+31.0%).

Other non-operating income

Other non-operating income was Ch$23,960 million (US$40.9 million), compared to
Ch$1,635 million (US$2.8 million) in the first quarter of 2004. Other
non-operating income in 1Q 2005 was mainly composed of a gain on the sale and
exchange of shares of Almacenes Paris amounting to Ch$20,965 million (US$35.8
million), explaining the difference between the two quarters.

Amortization of goodwill expense

Amortization of goodwill expense amounted to Ch$5,115 million (US$8.7 million)
in the first quarter of 2005, almost unchanged from the Ch$5,179 million (US$8.8
million) reported in the same period of 2004. Goodwill expense is almost
entirely related to the Banco de Chile acquisition in 2001, and to a lesser
extent, the Banco Edwards acquisition in 1999 (now kept on the books as Bank of
Chile). Of the total balance of goodwill at the consolidated level of Ch$296,184
million (US$505.5 million) as of March 31, 2005, Ch$279,271 million (US$476.6
million) was associated with the Banco de Chile acquisition. Goodwill is
amortized using the straight-line method over twenty years.

Interest Expense

Interest expense for the first quarter of 2005 amounted to Ch$7,013 million
(US$12.0 million), a reduction of 19.2% compared to the same period in 2004. The
decrease corresponds to lower interest expense at Madeco, Telsur and the
corporate level due to a lighter consolidated debt load (Madeco and Telsur) and
low prevailing interest rates.

Price-level restatement and foreign currency translation losses

Price-level restatement and foreign currency translation losses amounted to
Ch$171 million (US$0.3 million) in the first quarter of 2005, compared to gains
of Ch$735 million (US$1.3 million) in the same period in 2004. In 1Q 2005, the
losses specific to foreign currency differences amounted to Ch$78 million
(US$0.1 million), down from the losses of Ch$519 million (US$0.9 million)
reported in the first quarter of 2004, primarily attributable to Madeco's
operations as a result of the financial restructuring carried out in 2004 that
reduced Madeco's exposure to the US dollar as well as the revaluation of the
Chilean peso vis-a-vis the US dollar during the quarter. Price-level restatement
losses amounted to Ch$93 million (US$0.2 million), compared to gains of Ch$1,254
million (US$2.1 million) in 1Q 2004.

Income Taxes - 1Q 2005

Quinenco reported income tax expense of Ch$5,490 million (US$9.4 million),
compared to income tax expense of Ch$1,789 million (US$3.1 million) in the same
period of 2004. The increase mainly corresponded to corporate level provisions
for taxes related to the sale and exchange of Almacenes Paris.

Minority Interest - 1Q 2005

In the first quarter of 2005, Quinenco reported a deduction from income of
Ch$2,506 million (US$4.3 million), compared to a deduction from income of
Ch$1,520 million (US$2.6 million) in 1Q 2004. The amount is mainly related to
minority shareholders' proportionate share of Madeco's and Telefonica del Sur's
first quarter 2005 income.

Current Assets

Current assets increased 31.9% compared to the fourth quarter of 2004, mainly

shares held in Almacenes Paris (as part of Cencosud's tender offer).

Fixed Assets and Other Assets

Fixed assets did not vary significantly from the fourth quarter of 2004. Other
assets decreased by 4.7%, mainly due to the sale of 27.3% of Almacenes Paris.

primarily due to a reduction in bank obligations at the corporate level.

Long-term Liabilities

2004.

Minority Interest

Minority interest increased by 5.2% compared to the fourth quarter of 2004,

1Q 2005 Results

Operating revenues increased by 0.6% to Ch$109,445 million (US$186.8 million) in
the first quarter of 2005. The rise in operating revenues was partially due to a
2.0% increase in the amount of fee income earned during the first quarter of the
year, which reached Ch$30,480 million (US$52.0 million), equivalent to 27.8% of
total operating revenues, mainly as a result of higher fee income generated by
the stock brokerage subsidiary. Likewise, net financial income, which increased
by 5.8% to Ch$77,679 million (US$132.6 million) contributed to the higher level
of operating revenues due to the growth in average interest earning assets and a
better funding mix. Net financial income, which is calculated as the sum of net
interest revenue and foreign exchange transactions (net), comprised 71.0% of
operating revenues in 1Q 2005. The aforementioned increases in operating
revenues were partially offset by a reduction of 76.7% in gains on sales of
financial instruments (net), which were affected by low returns from the sale of
Central Bank and bank issued mortgage bonds, the effect amounting to a decline
of Ch$4,225 million (US$7.2 million) in 1Q 2005.

Provisions, which amounted to Ch$13,499 million (US$23.0 million), showed a
decrease of 8.7% from the Ch$14,788 million (US$25.2 million) reported in the
first quarter of 2004, reflecting a healthier loan portfolio in line with
improved economic conditions.

Other income and expenses amounted to Ch$6,615 million (US$11.3 million), an
increase of 92.4% over the Ch$3,439 million (US$5.9 million) reported in 1Q
2004. Other income and expenses was mainly composed of loan recoveries
previously written off.

--------------------------------------------------------------------------------

Operating expenses rose by 7.7% to Ch$61,028 million (US$104.2 million) compared
to the first quarter of 2004, primarily due to higher personnel and
administrative expenses reflecting headcount of an additional 297 employees.

Price-level restatement gains totaled Ch$3,929 million (US$6.7 million) compared
to price-level restatement gains of Ch$2,653 million (US$4.5 million) reported
in 1Q 2004. The gains in 1Q 2005 reflect the higher negative inflation rate in
1Q 2005 vis-a-vis 1Q 2004.

Net income increased by 5.4% reaching Ch$40,839 million (US$69.7 million) in 1Q
2005, driven by a solid operational performance, lower loan loss provisions,
higher loan loss recoveries and reduced non-operating expenses. The effect of
these increases on net income was partially offset by the aforementioned rise in
operating expenses associated with the personnel and administration areas.

As of March 2005, the Bank's loan portfolio (net of inter-bank loans) had grown
by 9.2% over the last twelve month period, mostly in commercial, consumer and
contingent loans, driven by the dynamic economic scenario.

Banco de Chile is the second ranked bank in the country with a market share of
17.5% according to information published by the Chilean Superintendency of Banks
for the period ended March 31, 2005. Its return on capital and reserves after
taxes (annualized) reached 31.5%, compared to 18.3% for the local financial
system, according to the same source.

--------------------------------------------------------------------------------

1Q 2005 Results

CCU's sales in the first quarter of 2005 grew by 10.6% compared to the first
quarter of 2004, due to an increase in consolidated sales volumes, partially
offset by lower average prices. The growth in sales volume was led by the
Chilean beer segment (+12.0%), the Argentine beer segment (+7.7%), the soft
drink, nectar and mineral water segment (+10.2%), the Chilean wine segment
(+3.6%) and the Argentine wine segment (+72.8%). The 0.4% decrease in average
prices was attributable to the Chilean beer segment (-2.4%) and the soft drinks
segment (-1.8%), partially offset by higher prices associated with the Argentine
beer and wine segments.

--------------------------------------------------------------------------------

Operating income increased by 4.1% to Ch$24,697 million (US$42.2 million) due to
the higher sales level, the effect of which was partially offset by an increase
in COGS and SG&A expenses. The consolidated operating margin was 19.8% of sales,
compared to 21.0% in the same period of 2004.

CCU reported non-operating losses of Ch$1,321 million (US$2.3 million), down
from the Ch$2,068 million (US$3.5 million) reported in 1Q 2004. The improvement
in non-operating results was primarily attributable to a reduction in interest
expenses as a consequence of a lighter debt load and low prevailing interest
rates. Additionally, non-operating results benefited from an increase in the
amount of interest income earned during the period due to larger average cash
balances on hand and higher interest rates on deposits.

Net income was Ch$19,026 million (US$32.5 million), an increase of 14.2% from
the net income of Ch$16,661 million (US$28.4 million) reported in the first
quarter of 2004. The rise in period profits was due to the improvement in
operating and non-operating results during the quarter, as well as a reduction
in income taxes, which in 1Q 2004 included extraordinary charges related to
prior periods.

1Q 2005 Results

Telefonica del Sur's revenues, which reached Ch$12,895 million (US$22.0 million)
in the first quarter of 2005, varied slightly from the Ch$12,830 million
(US$21.9 million) reported in the first quarter of 2004. Nonetheless, the
revenue mix favored non-regulated services such as wide band internet, security
services and data transmission services which made up 29.6% of revenues in 1Q
2005, compared to 25.7% in the same period of 2004.

Revenue from Internet, security services and data transmission grew by 15.5%
during the first quarter reaching Ch$3,813 million (US$6.5 million). Most
notable was the growth experienced in Internet services whose client base now
includes 28,199 clients, implying an increase in revenue for the quarter of
Ch$571 million (US$1.0 million).

The decline in revenue associated with Telsur's traditional services such as
fixed telephony, access charges, long distance and public telephony services was
partially offset by prepaid and fixed price bundling of phone services however,
substitution of fixed telephony for mobile telephony and other alternatives
continue to capture a portion of the company's traditional sale base.

--------------------------------------------------------------------------------

Basic telephony services accounted for 46.3% of all revenues, followed by user
access charges (9.4%), long distance services (8.6%), public telephones (6.1%),
and other non-regulated services (29.6%).

Operating profit remained stable at Ch$2,889 million (US$4.9 million), compared
to Ch$2,901 million (US$5.0 million) in the first quarter of 2004. The slight
drop in operating income in 1Q 2005 (0.4%) mainly corresponded to an increase in
SG&A expenses associated with salaries expense.

Telsur reported non-operating losses of Ch$571 million (US$1.0 million), down by
18.6% from the non-operating losses of Ch$702 million (US$1.2 million) reported
in 1Q 2004. The decline in non-operating losses was primarily attributable to
lower interest expense as a consequence of a lighter debt load and low
prevailing interest rates and an increase in interest income.

Telsur reported net income of Ch$1,751 million (US$3.0 million), an increase of
5.1% compared to the same period in 2004, mainly as a result of the
aforementioned improvement in non-operating performance during the quarter.

1Q 2005 Results

Madeco's sales in the first quarter of 2005 increased by Ch$11,239 million
(US$19.2 million) or 14.9% from Ch$75,494 million (US$128.8 million) to
Ch$86,733 million (US$148.0 million), primarily attributable to higher volume
sales and price increases associated with the wire and cable business unit,
which rose by 32.8% or Ch$12,676 million (US$21.6 million). Additionally, the
flexible packaging and aluminum profiles business units experienced sales
increases of 2.2% and 2.7%, respectively, although the effect of the growth in
sales at a consolidated level was partially offset by a decline in brass mill
sales of 9.4%.

Wire and cable sales benefited from strong demand for copper rod and copper and
aluminum cables, particularly in Brazil. Sales of the brass mill unit, which
declined by Ch$1,845 million (US$3.2 million) were affected by low volume in
Chile and a reduction in exports, although this was partially offset by an
increase in volume sales in Argentina and higher average prices.

Sales of the wire and cable business unit (whose principal operation is Ficap
Brazil) accounted for 59.1% of total sales, followed by brass mills (20.4%),
flexible packaging (12.2%) and aluminum profiles (8.3%).

--------------------------------------------------------------------------------

Operating income rose by 20.6% to Ch$7,294 million (US$12.4 million), mainly due
to the 165.7% or Ch$3,014 million (US$5.1 million) increase in operating income
associated with the cable business unit. The marked increase in the operating
income of this business unit was a direct result of the sales increase
experienced during the quarter as well as an 11.4% decline in SG&A expenses. The
increase in consolidated income was partially offset by decreases in the
operating income earned in the brass mills, flexible packaging and aluminum
profiles business units. As a percentage of sales, the operating margin reached
8.4%, up from 8% one year ago.

Non-operating losses were cut by 31.4% to Ch$1,943 million (US$3.3 million)
versus Ch$2,835 million (US$4.8 million) in 1Q 2004. The decrease in
non-operating losses was mainly attributable to an increase in other
non-operating income associated with a reduction in provisions related to the
Optel subsidiary in Brazil and a sharp 19.0% reduction in interest expense as a
consequence of a lower debt level and low prevailing interest rates.

Madeco reported a net profit of Ch$3,829 million (US$6.5 million) for the first
quarter of 2005, compared to net income of Ch$1,729 million (US$3.0 million) in
1Q 2004. The improvement in net quarterly earnings was attributable to the
improvement in both operating and non-operating results vis-a-vis one year ago.
