(BANCOLOMBIA LETTERHEAD)

                      BANCOLOMBIA: ADDITIONAL ANNOUNCEMENT

Medellin, Colombia, January 05, 2006

Mr. Ricardo Calvete Rangel, the attorney of Mr. Jorge Londono Saldarriaga,
President of Bancolombia, S.A. ("Bancolombia"), was notified today of the
resolution issued by the General Attorney's Office on January 4, 2007, which
authorizes the prosecution of Mr. Jorge Londono Saldarriaga and Mr. Federico
Ochoa B., Executive and Services Vice President of Bancolombia.

After reviewing the resolution, in our opinion, we find major flaws that we
expect to be corrected immediately by the prosecutor and Mr. Jorge Londono
Saldarriaga, through his attorney, will initiate the necessary actions and
proceedings to correct the significant errors that the prosecutor has made.

The decision of the prosecutor does not affect the equity of Bancolombia or its
solvency, its business and operations, or its obligations with its customers and
clients.

During the acquisition and merger process, Bancolombia and its officers acted
with the highest degree of loyalty and transparency, and the transactions
conducted with the shareholders followed the requirements established by law.

Neither Bancolombia nor its officers have made any improper use of public funds,
nor have they appropriated any such funds. On the contrary, all funds entrusted
to Bancolombia by our clients have been managed with the highest degree of care.

Bancolombia's acts in the acquisition and merger process have been thoroughly
analyzed at various judicial and administrative levels, including the Supreme
Court of Justice, the State Council ("Consejo de Estado"), the Administrative
Tribunal of Cundinamarca ("Tribunal Contencioso Administrativo de
Cundinamarca"), the Superior Court of Bogota, the Superior Court of Medellin and
three arbitration panels, and the former Superintendencies of Banking and
Securities (currently the Superintendency of Finance of Colombia). These
multiple levels of review have cleared Bancolombia and its officers and
directors of the same fraud charges which are now being pressed by the
prosecutor against these officers of Bancolombia. Indeed, the prosecutor's
actions contradict previous decisions of the first and second instances of the
same prosecutor.

The officers of Bancolombia, through their attorneys will continue to work on
this matter with the highest diligence and will initiate all available judicial
proceedings against the unexpected decision of the prosecutor.
