            UNCONSOLIDATED NET INCOME OF PS 63,380 MILLION IN OCTOBER
             TOTALING PS 457,266 FOR THE FIRST TEN MONTHS OF 2006 *

MEDELLIN, COLOMBIA. NOVEMBER 10, 2006

BANCOLOMBIA reported unconsolidated net income of Ps 63,380 million for the past
month of October, accumulating Ps 457,266 million for the first ten months of
2006.

During October, total net interest income, including investments amounted to Ps
141,199 million. Additionally, total net fees and income from services amounted
to Ps 49,015 million in the month.

As of October 31, 2006, BANCOLOMBIA's total assets amounted to Ps 25.60
trillion, total deposits totaled Ps 16.61 trillion and total shareholders'
equity amounted to Ps 3.26 trillion.

Also as of October 31, 2006, BANCOLOMBIA's level of past due loans as a
percentage of total loans was 2.51% and the level of allowance for past due
loans was 140.20%.

As previously announced on October 12, 2006, BANCOLOMBIA purchased
mortgage-backed securities called TIPS, indexed to the UVR (Unidad de Valor
Real), for approximately Ps 490,000 million in a public offering made by
Titularizadora Colombiana S.A. All such TIPs were classified as "Held to
Maturity".

Other operating income amounted to $35,896 million in October basically due to
two non recurrent events:

     -    BANCOLOMBIA sold through the Colombian Stock Exchange (Bolsa de
          Valores de Colombia), the last part of the stake it held in
          Corfinversiones (now Compania de Suramericana de Inversiones S.A.)
          which was received as a result of the spin-off of Corfinsura S.A..
          Since Colombian regulations do not allow banks to have equity
          investments in non-financial companies, the Superintendency of Finance
          determined that BANCOLOMBIA would have a period of two years to sell
          such investment. BANCOLOMBIA's profits from the sale of such
          investment amounted to Ps 24,193 million.

     -    BANCOLOMBIA sold mortgage loans to Titularizadora Colombiana amounting
          to approximately Ps. 580,000 million. These mortgage loans were
          secured by the Titularizadora through the issuance of securities TIPS.
          BANCOLOMBIA's profits from the sale of such interest earning mortgage
          loans amounted to Ps 11,651 million.

MARKET SHARE

According to ASOBANCARIA (Colombia's national banking association),
BANCOLOMBIA's market share of the Colombian Financial System in October 2006 was
as follows: 17.8% of total deposits, 20.6% of total net loans, 18.0% of total
savings accounts, 21.6% of total checking accounts and 14.3% of total time
deposits.
