BANCOLOMBIA S.A ANNOUNCES THAT THE SUPERIOR COURT OF BOGOTA DISMISSES
THE ANNULMENT ACTION FILED BY THE BANK
Medellín, Colombia, March 5, 2008
Today the Superior Court of Bogota dismissed a complaint filed by Bancolombia S.A (Bancolombia)
on February 17, 2004 that sought the annulment of a January 30, 2004 arbitral award (the Arbitral
Award) of compensation to a class of minority shareholders of the former Banco de Colombia. The
court rejected the grounds for annulment advanced by Bancolombia.
Under the Arbitral Award, shareholders of the former Banco de Colombia will be entitled to
compensation if they: (i) fulfill the requirements established in articles 55 and 66 of Law 472 of
1998, (ii) fulfill the requirements established in the Arbitral Award, (iii) timely became parties
to the class action or have timely accepted the outcome of the Arbitral Award, and (iv) have not
elected to be excluded from the Class Action or its outcome.
Bancolombia notes that it has taken a provision in its financial statements for the full amount of
the compensation awarded and that payment of the Arbitral Award will have no material effect on its
financial statements.
Background of the Proceedings
An arbitral tribunal (the Arbitral Tribunal) was formed after Mr. Luis Alberto Durán Valencia and
other minority shareholders filed a complaint against Bancolombia and some of its majority
shareholders in the context of the merger between Banco de Colombia and Bancolombia. The Arbitral
Tribunal rendered the Arbitral Award on January 30, 2004, rejected most of the claims of Mr. Durán
Valencia and the other plaintiffs, and released the shareholders of Bancolombia of all liability.
The Arbitral Tribunal found that Bancolombias actions in the acquisition of, and subsequent merger
with, Banco de Colombia were in compliance with the law and with the authorizations granted by the
government authorities. The Arbitral Tribunal, however, ordered Bancolombia to compensate
shareholders of the former Banco de Colombia for certain asserted damages.
According to the Arbitral Tribunal, these former shareholders of Banco de Colombia were damaged by
an alleged shortfall in the capitalization of Bancolombia after the merger in 1998. The Arbitral
Tribunal estimated the damages to be Ps. 14,646 million, which, with interest, amounted at the time
of the Arbitral Award to Ps. 22.408 million. After subtracting certain fees and expenses awarded to
Bancolombia by the Arbitral Tribunal, Bancolombia was directed to pay Ps.19,213 million.
Bancolombia notes that one of the arbitrators, Mr. Rafael H. Gamboa, dissented from the majority
decision of the Arbitral Tribunal. Mr. Gamboa concluded that the conduct of Bancolombia during the
merger was entirely in accordance with the applicable laws and the authorizations by governmental
authorities and that Bancolombia owed no compensation to the complaining shareholders.
Bancolombia filed the complaint seeking annulment of the Arbitral Award on February 17, 2004. The
Annulment Complaint sought annulment on the grounds set forth in sections 6 and 7 of article 163
of Decree 1818 of 1998.
