      million), attributable to the strong quarterly sales growth at Madeco of
      31.1%.

      from the Ch$7,867 million (US$15.0 million) reported in the first quarter

      Net Income - 1Q 2006
      -----------------------

         Quinenco reported net income for the first quarter of 2006, which
         amounted to Ch$14,921 million (US$28.4 million), compared to net income
         of Ch$30,309 million (US$57.6 million) in the first quarter of 2005. 1Q
         2005 income (at the Quinenco holding company level) included a
         non-recurring gain on the sale and exchange of shares of Almacenes
         Paris of Ch$21,825 million (US$41.5 million), mainly explaining the
         variation in net income between the two quarters.

         The net income contribution from operating companies reached Ch$24,707
         million (US$47.0 million), up by 8.3% compared to the same quarter in
         2005. 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.

      Revenues - 1Q 2006
      ---------------------

      Consolidated revenues for the first quarter of 2006 were Ch$132,212
      million (US$251.3 million), up by 26.7% from the Ch$104,344 million
      (US$198.3 million) reported in the first quarter of 2005, mostly explained
      by a 31.1% increase in Madeco's sales as a result of higher volume sales
      in its main markets and price increases associated with the rise in copper
      prices.


                                                                    Page 3 of 11

      Operating Income - 1Q 2006
      -----------------------------

      Operating income for the first quarter of 2006 was Ch$10,258 million
      (US$19.5 million), up by 30.4% from the Ch$7,867 million (US$15.0 million)
      reported in the first quarter of 2005. The sharp rise in consolidated
      operating income was attributable to Madeco's operations, mainly due to
      the increase in operating income associated with the cable and flexible
      packaging business units.

      ----------------------
      EBITDA - 1Q 2006
      ----------------------

      operations.

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

      Quinenco reported non-operating income of Ch$11,153 million (US$21.2

      Ch$30,456 million (US$57.9 million) in the same quarter of 2005. 1Q 2005
      non-operating income included a non-recurring gain on the sale and
      exchange of shares of Almacenes Paris of Ch$21,825 million (US$41.5
      million), mainly explaining the variation in results between the two
      quarters. The main items included in non-operating results are discussed
      below:

            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$21,235
            million (US$40.4 million), compared to Ch$19,914 million (US$37.8
            million) in 1Q 2005, an increase of 6.6%. The increase corresponded
            to growth in the proportionate share of net income from Banco de
            Chile (+3.4%), CCU (+10.6%) and Entel (+17.9%).

            ----------------------------
            Other non-operating income
            ----------------------------

            Other non-operating income was Ch$508 million (US$1.0 million),
            compared to Ch$24,943 million (US$47.4 million) in the first quarter
            of 2005. 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$21,825 million (US$41.5 million), explaining the
            difference between the two quarters.

            ----------------------------------
            Amortization of goodwill expense
            ----------------------------------

            Amortization of goodwill expense amounted to Ch$5,239 million
            (US$10.4 million) in the first quarter of 2006, almost unchanged
            from the Ch$5,325 million (US$10.1 million) reported in the same
            period of 2005. 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. As of March 31, 2006, goodwill amounting to Ch$266,496
            million (US$506.5 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 2006 amounted to Ch$6,967
            million (US$13.2 million), a reduction of 4.6% compared to the same
            period in 2005. The decrease corresponds to lower interest expense
            at Telefonica del Sur and the corporate level.

            -------------------------
            Price-level restatement
            -------------------------

            Price-level restatement gains amounted to Ch$698 million (US$1.3
            million) in the first quarter of 2006, compared to price-level
            restatement losses of Ch$96 million (US$0.2 million) in the same
            period in 2005.

            ---------------------------------------
            Foreign Currency Exchange Differences
            ---------------------------------------

            In 1Q 2006, the gains specific to foreign currency differences
            amounted to Ch$1,408 million (US$2.7 million), compared to losses
            amounting to Ch$81 million (US$0.2 million) reported in the first
            quarter of 2005, almost entirely attributable to Madeco's operations
            as a result of the revaluation of the Brazilian real and its effect
            on US dollar denominated debt in Ficap (Brazil).

      ----------------------------
      Income Taxes - 1Q 2006
      ----------------------------

      Quinenco reported income tax expense of Ch$2,394 million (US$4.5 million),
      compared to Ch$5,715 million (US$10.9 million) in the same period of 2005.
      In 1Q 2005, provisions for income taxes included the estimated tax
      liability associated with the disposal of Almacenes Paris, which mainly
      explains the variation during the two quarters.

      ----------------------------
      Minority Interest - 1Q 2006
      ----------------------------

      In the first quarter of 2006, Quinenco reported a deduction from income of
      Ch$4,477 million (US$8.5 million), compared to a deduction from income of
      Ch$2,609 million (US$5.0 million) in 1Q 2005. The amount is mainly related
      to minority shareholders' proportionate share of Madeco's and Telefonica
      del Sur's first quarter 2006 income.

      Current assets increased 25.5% compared to the fourth quarter of 2005,

      receipt of dividends and a higher stock and accounts receivable level at
      Madeco.

      Fixed Assets and Other Assets
      -------------------------------

      Fixed assets did not vary significantly from the fourth quarter of 2005.

      Current Liabilities
      --------------------

      Current liabilities increased by 23.8% compared to the fourth quarter of

      finance additional working capital needs as a result of the higher sales
      level and rising copper prices.

1Q 2006 Results
-------------------

Operating revenues increased by 10.7% to Ch$126,291 million (US$240.0 million)
in the first quarter of 2006. The rise in operating revenues was primarily due
to an increase in net financial income, which rose by 13.1% to Ch$91,451 million
(US$173.8 million) as a result of a 6.8% growth in average interest earning
assets, higher results associated with demand deposits as a result of higher
nominal interest rates and a better asset mix compared to 1Q 2005. Net financial
income, which is calculated as the sum of net interest revenue and foreign
exchange transactions (net), comprised 72.4% of operating revenues in 1Q 2006.
To a lesser extent, an increase of Ch$3,122 million (US$5.9 million) in gains on
the sale of financial instruments also contributed


                                                                    Page 7 of 11

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

to the increase in operating revenues during the first quarter of the year.
These gains, which amounted to Ch$4,461 million (US$8.5 million) were the result
of higher earnings on the sale of local, foreign and mortgage finance bonds. Fee
income, a component of operating revenues, fell by 4.8% to Ch$30,379 million
(US$57.7 million), mainly attributable to higher fees paid to the sales force,
lower fee income earned by the bank's stock brokerage subsidiary and lower
income from sales of assets received in lieu of payment, the effect of which was
partially offset by higher income from the mutual funds and insurance
subsidiaries. Fee income accounted for 24.1% of operating revenues in 1Q 2006.

Provisions, which amounted to Ch$6,633 million (US$12.6 million), showed an
increase of 14.7% from the Ch$5,785 million (US$11.0 million) reported in the
first quarter of 2005, mainly due to a decrease in recoveries of loans
previously charged off associated with the wholesale market. This reflected a
0.3% provision to average loans (compared with 0.9% for the financial system as
a whole).

Operating expenses rose by 9.5% to Ch$70,579 million (US$134.1 million) compared
to the first quarter of 2005, primarily due to higher administrative expenses
associated with the US branches, advertising and promotional expenses to support
business growth in the retail banking area and an increase in the headcount of
1,007 employees, mainly in the bank's commercial area.

Price-level restatement gains totaled Ch$1,666 million (US$3.2 million) compared
to price-level restatement gains of Ch$4,090 million (US$7.8 million) reported
in 1Q 2005. The reduction in gains in 1Q 2006 reflect the lower negative
inflation rate used for adjustment purpose sin 1Q 2006 vis-a-vis 1Q 2005 (-0.3%
vs. -0.8%).

Net income increased by 6.2% reaching Ch$45,135 million (US$85.8 million) in 1Q
2006, driven by the aforementioned 13.1% increase in net financial income and
gains on the sale of financial instruments, the effect of which more than offset
the rise in operating expenses reported during the first quarter of the year.

As of March 2006, the Bank's loan portfolio (net of inter-bank loans) had grown
by 12.9% 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
17.7% according to information published by the Chilean Superintendency of Banks
for the period ended March 31, 2006. Its return on capital and reserves after
taxes (annualized) reached 29.0%, compared to 18.5% for the local financial
system, according to the same source.

1Q 2006 Results
-------------------

CCU's sales in the first quarter of 2006 grew by 7.5% compared to the first
quarter of 2005, due to an increase in consolidated sales volumes and higher
average prices. The growth in sales volume was led by the Chilean beer segment
(+8.1%), the soft drink, nectar and mineral water segment (+6.6%), the pisco
segment (+48.8%), and the Argentine beer segment (+1.1%). The increase in
volumes was partially offset by an 8.2% decline in wine volume. Higher average
prices correspond to Chilean beer, pisco and mineral water, the effect of which
was partially offset by lower average price of Argentine beer, nectars, soft
drinks and wine.

Operating income increased by 4.3% to Ch$26,808 million (US$50.9 million) due to
the higher sales level, the effect of which was partially offset by an increase
in COGS and SG&A expenses associated with higher marketing and distribution
expenses. The consolidated operating margin was 19.2% of sales, compared to
19.8% in the same period of 2005.

CCU reported non-operating losses of Ch$1,304 million (US$2.5 million), down
from the Ch$1,375 million (US$2.6 million) reported in 1Q 2005. The slight
improvement in non-operating results was attributable to a variety of factors,
including improved FX results, price-level restatement results and a higher
level of other non-operating income, the effect of which was partially offset by
an increase in interest expense.

Net income amounted to Ch$20,414 million (US$38.8 million), an increase of 3.1%
from the net income of Ch$19,806 million (US$37.6 million) reported in the first
quarter of 2005. The rise in period profits was due to the aforementioned
improvement in operating and non-operating results during the quarter, partially
offset by an increase in income tax provisions during the period.

1Q 2006 Results
--------------------

Telefonica del Sur's revenues, which reached Ch$13,546 million (US$25.7 million)
in the first quarter of 2006, varied only slightly from the Ch$13,423 million
(US$25.5 million) reported in the first quarter of 2005. Nonetheless, the
revenue mix favored non-regulated services such as wide band internet, security
services and data transmission services which made up 26.9% of revenues in 1Q
2006, compared to 23.7% in the same period of 2005.

Revenue from Internet, security services and data transmission grew by 14.2%
during the first quarter reaching Ch$3,640 million (US$6.9 million). Most
notable was the growth experienced in Internet services whose client base now
includes 39,732 clients, implying an increase in revenue for the quarter of
Ch$336 million (US$0.6 million).

Revenue associated with Telefonica del Sur's fixed telephony and access charges
which made up 56.1% of sales in 1Q 2006, fell by 6.0% to Ch$7,598 million
(US$14.4 million) as 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 45.7% of all revenues, followed by user
access charges (10.4%), long distance services (8.1%), public telephones (5.7%),
and other non-regulated services (30.1%).

In spite of the change the company is undergoing in revenue base, operating
profit increased by 2.2% to Ch$3,075 million (US$5.8 million), compared to
Ch$3,008 million (US$5.7 million) in the first quarter of 2005. The rise in
operating income in 1Q 2006 mainly corresponded to a reduction in SG&A expenses.

Telefonica del Sur reported non-operating losses of Ch$391 million (US$0.7
million), down by 34.2% from the non-operating losses of Ch$595 million (US$1.1
million) reported in 1Q 2005. The decline in non-operating losses was primarily
attributable to lower interest expense as a consequence of a lighter debt load.

Telefonica del Sur reported net income of Ch$2,086 million (US$4.0 million), an
increase of 14.5% compared to the same period in 2005, mainly as a result of the
aforementioned improvement in operating and non-operating performance during the
quarter.

1Q 2006 Results
---------------------

Madeco's sales in the first quarter of 2006 increased by Ch$28,078 million
(US$53.4 million) or 31.1% from Ch$90,289 million (US$171.6 million) to
Ch$118,367 million (US$225.0 million), primarily attributable to higher volume
sales and price increases associated with the rise in copper prices. The wire
and cable business unit, whose sales increased by 43.2% or Ch$23,088 million
(US$43.9 million), accounted for 82.2% of the total sales increase during 1Q
2006. Additionally, brass mills sales rebounded during the quarter, rising by
Ch$4,622 million (US$ 8.8 million) or 25.1% compared to the same period last
year.

Wire and cable sales benefited from strong demand, particularly in Argentina,
Brazil and Peru. Sales of the brass mills unit benefited from volume increases
in Chile, a rise in export sales and higher copper prices. Sales of the wire and
cable business unit (whose principal operation is Ficap Brazil) accounted for
64.6% of total sales, followed by brass mills (19.5%), flexible packaging (9.3%)
and aluminum profiles (6.6%).

Operating income rose by Ch$1,918 million (US$3.6 million) or 25.3% to Ch$9,512
million (US$18.1 million), mainly due to the increase in operating income
associated with the cable and flexible packaging business units. The marked
increase in the operating income of the cable business unit (+Ch$1,255 million
or US$2.4 million) was a direct result of the sales increase experienced during
the quarter. The improvement in the operating income of the flexible packaging
unit was related to greater operating efficiencies and lower SG&A expenses. The
increase in consolidated income was partially offset by a decline in the
operating income associated with the brass mills unit which was affected by the
revaluation of the Chilean peso vis-a-vis the US dollar on its exports and
greater competition from imports in Chile. As a percentage of sales, the
operating margin was 8.0%, down from 8.4% one year ago.

Non-operating losses were cut by 56.1% to Ch$888 million (US$1.7 million) in 1Q
2006. The decrease in non-operating losses was mainly attributable to exchange
rate gains associated with the revaluation of the Brazilian real and its effect
on US dollar denominated debt in Ficap (Brazil).

Madeco reported a net profit of Ch$6,451 million (US$12.3 million) for the first
quarter of 2006, up by 61.9% compared to the net income of Ch$3,986 million
(US$7.6 million) reported in 1Q 2005. The improvement in net quarterly earnings
was attributable to the improvement in operating and non-operating results
compared to the same period of 2005.
