           UNCONSOLIDATED NET INCOME OF PS 43,849 MILLION IN NOVEMBER
        TOTALING PS 501,115 MILLION FOR THE FIRST ELEVEN MONTHS OF 2006 *

MEDELLIN, COLOMBIA, DECEMBER 13, 2006

BANCOLOMBIA reported unconsolidated net income of Ps 43,849 million during the
past month of November, accumulating Ps 501,115 million for the first eleven
months of 2006.

During November, total net interest income, including investment securities
amounted to Ps 129,230 million. Additionally, total net fees and income from
services totaled in the month Ps 50,633 million.

Total assets amounted to Ps 25.84 trillion in November 2006, total deposits
totaled Ps 16.37 trillion and BANCOLOMBIA's total shareholders' equity amounted
to Ps 3.29 trillion.

BANCOLOMBIA's (unconsolidated) level of past due loans as a percentage of total
loans was 2.57% as of November 30, 2006, and the level of allowance for past due
loans was 135.33%.

In November, there were no provisions for income taxes, due to adjustments to
the calculation of total income taxes for the fiscal year 2006.

On the other hand, the increase in bonus plan payment provisions is explained by
the increased growth in the number of employees included in the bank's system of
variable compensation, the purpose of which is to align the objectives of the
bank's management with the shareholders' interests.

MARKET SHARE

According to ASOBANCARIA (Colombia's national banking association),
BANCOLOMBIA's market share of the Colombian Financial System in November 2006
was as follows: 17.8% of total deposits, 20.6% of total net loans, 18.2% of
total savings accounts, 20.7% of total checking accounts and 14.4% of total time
deposits.
