                                         Name:  Jaime Alberto Velasquez B.
                                         Title: Vice President of Finance




On June 26, 1995, Colombian Industrial Bank filed with the U.S. Securities and
Exchange Commission (the "SEC") a registration statement under the U.S.
Securities Act of 1933 (the "Securities Act") on Form F-1 in connection with the
initial public offering and listing of its ADRs. Colombian Industrial Bank also
filed Form 8-As on July 7, 1995 and July 24, 1995 with the SEC to register its
ADRs and underlying preferred shares under the U.S. Securities Exchange Act of
1934 (the "Exchange Act"). In conjunction with those filings, Colombian
Industrial Bank was issued a CIK number, a Securities Act file number and an
Exchange Act file number by the SEC. In 1998, Colombian Industrial Bank merged
with another Colombian bank and changed its name to Bancolombia S.A.
("Bancolombia" or "BC"). On September 30 of that year, Bancolombia filed a
registration statement under the Securities Act on Form F-3 to register
additional ADRs and underlying preferred shares. At that time, Bancolombia was
issued an additional CIK number and an additional Securities Act file number by
the SEC. Based on discussions among Bancolombia and the SEC, it appears the
issuance of an additional CIK number at that time was unnecessary. Since 1998,
Bancolombia has made all but three of its filings with the SEC under its new CIK
number and Securities Act file number (it did not receive a new Exchange Act
file number). 

At the request of the SEC and in order to merge the filing histories of
Colombian Industrial Bank and Bancolombia to the extent practicable under the
EDGAR system, Bancolombia has filed today a Form 8-A under its current CIK
number to obtain an Exchange Act file number. 

All Bancolombia related filings dated prior to September 30, 1998 (which are all
paper filings) may still be found under Colombian Industrial Bank's CIK number:
947331. Bancolombia intends to make all future filings under its current CIK
number: 1071371, and all filings pursuant to the Exchange Act under its new
Exchange Act file number: 001-32535.
