     be understood as referring to the Bank together with its affiliates, unless
     otherwise specified. The unaudited pro forma combined condensed financial
     statements for the second quarter of 2005 and the relevant numbers
     developed from such financial statements presented below are derived from

     June 30, 2005 (b) the unaudited consolidated financial statements of
     Corporacion Financiera Nacional y Suramericana S.A. ("Corfinsura"), giving
     effect to the spin-off of the portion of Corfinsura's assets and
     liabilities that were not assumed by Bancolombia through the merger, as of
     June 30, 2005 and (c) the unaudited consolidated financial statements of
     Conavi Banco Comercial y de Ahorros S.A ("Conavi"), as of June 30, 2005, as

assurance can be given that any such savings or other expected benefits of the
merger will in fact take place, whether at the level of management's current
expectations or at all.

                                                                            2Q06

1.   HIGHLIGHTS(2):

     -    Despite positive operating results for the second quarter of 2006, the
          Bank's overall results were negatively impacted by the volatility of
          the international capital markets. The Colombian sovereign bonds
          sell-off, resulted in a drop in prices, as the benchmark TES 2020
          yield rose from 7.62%, at the end of the first quarter, to 10.50% as
          of June 30, 2006. This drove interest on investments to a loss of Ps
          158,401 million, compared to the Ps 135,379 million gain from the
          first quarter and to Ps 228,791 million gain from the second quarter
          of 2005.

     -    As a result, net income for the second quarter of 2006 amounted to Ps
          69,048 million, decreasing 71.7% as compared to Ps 243,522 million pro
          forma for the second quarter of 2005, and 67.7% as compared to Ps
          214,102 million for the first quarter of 2006.

     -    As of June 30, 2006, BANCOLOMBIA's net loans totaled Ps 21,085
          billion, increasing 14.8% compared to Ps 18,365 billion in the
          previous quarter and 25.1% on a year-to-year basis. Similarly,
          interest on loans increased 4.7% quarterly and 8.1% yearly.

     -    The deposit mix improved for the quarter. Total deposits amounted to
          Ps 20,681 billion increasing 12.7% for the quarter and 20.2% for the
          year, while interest on deposits increased 5.4% for the quarter and
          decreased 1.1% for the year.

     -    Net fees and income from services totaled Ps 210,335 million for the
          quarter, increasing 19.6% compared to the pro forma figure for the
          same period in 2005, and increasing 2.1% from the quarter ended on
          March 31, 2006.

     -    The financial business grew during the first six months of 2006, while
          the operating expenses remained stable for the quarter and increased
          5.2% in a year over year basis, below the Bank's assets growth.

     -    BANCOLOMBIA's ratio of past due loans to total loans at June 30, 2006
          was 2.7% and the ratio of allowances to past due loans was 130.7%.

(2)  This is the fourth time BANCOLOMBIA has released consolidated quarterly
     financial results since the merger that took place on July 30, 2005. This
     report contains pro forma figures for the second quarter of 2005 as if the
     spin off of Corfinsura and the merger with Conavi and Corfinsura (after the
     spin-off) had taken place on that date, for the purpose of comparison. All
     references to numbers for periods prior to the merger contained herein were
     derived from such pro forma consolidated financial statements.

2.   CONSOLIDATED BALANCE SHEET

2.1  ASSETS

     BANCOLOMBIA's total assets for the quarter amounted to Ps 33,488 billion as
     of June 30, 2006, increasing 8.15% as compared to Ps 30,965 billion as of
     March 31, 2006. This represents an increase of 17.2% over the year from Ps
     28,569 billion as of June 30, 2005. The assets growth is a result of the
     positive dynamic of the loan portfolio.

2.1.1 LOAN PORTFOLIO

     The loan portfolio presented very positive figures amounting to Ps 21,085
     billion as of June 30, 2006, increasing 14.8% for the quarter and 25.1% on
     a year-to-year basis.

     Corporate loans presented a robust growth amounting to Ps 9,552 billion for
     the quarter, increasing 17.5% as compared to Ps 11,224 billion in the
     previous quarter. This represents an increase of 21.9% as compared to Ps
     9,208 billion for the same period of 2005.

     The retail and small and medium-sized enterprise ("SME") loans maintained
     their positive growth rates. They amounted to Ps 5,806 billion as of June
     30, 2006, increasing 12.3% over the quarter and 30.3% over the year.
     Similarly, financial leases maintain their positive trend amounting to Ps
     3,099 billion, increasing 8.7% over the quarter and 27.3% over the year.

     In March, the Bank implemented a new commercial strategy based on 1% per
     month fixed-rate ten year mortgages that resulted in a strong growth of the
     mortgage loans during the second quarter, amounting to Ps 1,719 billion as
     of June 30, 2006. This represents a 12.3% increase over the quarter, and an
     18.1% increase over the year.

3.   INCOME STATEMENT

     BANCOLOMBIA's net income amounted to Ps 69,048 million for the quarter
     ended June 30, 2006, as compared to Ps 214,102 million for the previous
     quarter and Ps 243,522 million pro forma for the second quarter of 2005.
     This represents a decrease of 67.8% and 71.7%, respectively, due to the
     losses resulting from the mark to market valuation of Colombian bond
     prices.

     Interest on loans totaled Ps 543,606 million for the second quarter of
     2006, increasing 4.7% as compared to Ps 519,316 million for the previous
     quarter and 8.1% compared to Ps 502,733 million pro forma for the second
     quarter of 2005. On the other hand, interests on investment securities were
     negatively impacted by the decrease of Colombian bond prices for the second
     quarter of 2006 amounting to a total loss of Ps 158,401 million.

     The most representative bond in the market is the COLOMBIA TES 20 which
     matures in July 2020. As illustrated below, this bond was traded at a yield
     of 7.62% as of March 31, 2006 and at 10.50% the end of the second quarter

3.4  OTHER OPERATING INCOME

     Other operating income totaled Ps 87,677 million during the second quarter
     of 2006, increasing 3.2% over the quarter and 72.8% over the year. This
     increase is mainly due to the net foreign exchange gains added to the
     forward contracts in foreign currency, which amounted to Ps 64,387 million
     during the quarter.


                                                                               7

3.5  OPERATING EXPENSES

     Total operating expenses were stable for the quarter, amounting to Ps
     412,462 million, which represents a 6.0% increase on a year-over-year
     basis.

     had a negative impact in the operating income of the Bank. BANCOLOMBIA's

     88.7% for the quarter. In a six month accumulated basis the income
     efficiency ratio reached 68.7%.

     The Bank's efficiency measured as operating expenses over average total
     assets was to 5.63% for the quarter and 5.58% during the first half of
     2006.

3.6  NON OPERATING INCOME - EXPENSES

     Non-operating income for the second quarter of 2006 increased due to
     non-recurrent events, amounting to Ps 55,515 million. Other income amounted
     Ps 121,284 million due to the recovery of differed taxes provisions from
     the investment portfolio and from the derivatives portfolio.

     Non-operating expenses amounted to Ps 64,224 million, primarily due to the
     following two events:

          1.   There were some adjustments as a result of the merger. The
               corporate dissolution of 3001 S.A. (a subsidiary of Conavi S.A.)
               took place during the quarter with two effects: a loss of Ps
               30,108 million accounted as "other expenses" and a gain accounted
               as "recovery of provisions for foreclosed assets and other
               assets" that amounted to Ps 33,632 million.

          2.   There was a provision of Ps 20,285 million corresponding to legal
               contingencies.
