                            A. ELECTION OF DIRECTORS
                            ------------------------
                                  (Proposal 1)

     The Board of  Directors is presently  comprised  of twelve  Directors.  The
Board is divided into three  classes,  and the members of each class hold office
for a term of three years unless  elected in the interim.  The term of one class
expires in each year.

     At the Meeting this year, four Directors are to be elected. General John R.
Galvin and Messrs.  William C. Morris and Robert L.  Shafer,  each of whose term
will expire at the 2003 Annual Meeting, and Mr. Robert B. Catell,  replacing Mr.
James Q.  Riordan,  who having  reached the age of 75, is  retiring  pursuant to
Board policy at the 2003 Annual Meeting,  have been  recommended by the Director
Nominating  Committee of the Board of Directors of the  Corporation for election
to the class whose term will expire in 2006.

     It is the intention of the persons named in the accompanying  form of Proxy
to  nominate  and to vote such  Proxy for the  election  of  General  Galvin and
Messrs.  Catell,  Morris and Shafer.  General  Galvin has been a Director of the
Corporation  since  1995,  Mr.  Morris has been a Director  and  Chairman of the
Corporation  since 1988,  and Mr. Shafer has been a Director of the  Corporation
since 1991.  General  Galvin and Messrs.  Morris and Shafer were last elected by
Stockholders at the 2000 Annual Meeting.

     Each nominee has agreed to serve if elected.  There is no reason to believe
that any of the nominees will become  unavailable  for election as a Director of
the  Corporation,  but if that should occur before the Meeting,  Proxies will be
voted for the persons the Board of Directors recommends.

     Background  information regarding General Galvin and Messrs. Catell, Morris
and Shafer, as well as the other Directors of the Corporation, follows.

                    B. RATIFICATION OF SELECTION OF AUDITORS
                    ----------------------------------------
                                  (Proposal 2)

     The Audit  Committee of the Board of  Directors  has  recommended,  and the
Board  of  Directors,  including  a  majority  of  those  members  who  are  not
"interested  persons"  of the  Corporation  (as  defined in the 1940  Act),  has
selected,  Deloitte & Touche LLP as auditors of the  Corporation  for 2003.  The
firm of Deloitte & Touche LLP has extensive  experience  in  investment  company
accounting  and  auditing.  It is expected that a  representative  of Deloitte &
Touche LLP will be present at the Meeting and will have the  opportunity to make
a statement and respond to questions.

     Deloitte & Touche LLP, in  accordance  with  Independence  Standards  Board
Standard No. 1, has confirmed to the Audit  Committee that they are  independent
auditors with respect to the Corporation.  Deloitte & Touche LLP has audited the
annual financial  statements of the Corporation and provided tax services to the

Manager,  Seligman Advisors, Inc., an affiliate of the Manager and Seligman Data
Corp.,  the stockholder  service agent for the  Corporation,  which is partially
owned by the Corporation (together, the "Affiliated Service Providers").

     In making its  recommendation,  the Audit Committee  considered whether the
provision by the independent  auditors to the Corporation of non-audit  services
to  the  Corporation  or of  professional  services  to the  Affiliated  Service
Providers is compatible  with  maintaining  the auditors'  independence  and has
discussed the auditors' independence with them.

     AUDIT  FEES.  For the fiscal  year ended  December  31,  2002,  the fee for

was also paid approximately  $2,000 for tax services and $2,609 for consultation

compliance testing,  $8,450 related to tax compliance and consultation  services
and $35,705 related to other services.

     The  affirmative  vote of a majority  of the votes  cast at the  Meeting is
required to ratify the selection of auditors.

   YOUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
   FOR THE RATIFICATION OF THE SELECTION OF DELOITTE & TOUCHE LLP AS AUDITORS
                              OF THE CORPORATION.

                                C. OTHER MATTERS

                                   APPENDIX 1

                           TRI-CONTINENTAL CORPORATION
                               (THE "CORPORATION")
                             AUDIT COMMITTEE REPORT

     The role of the Audit  Committee is to assist the Board of Directors in its
oversight  of the  Corporation's  financial  reporting  process.  The  Committee
operates  pursuant to a charter  that was last amended and restated by the Board
on March 15, 2001. As set forth in the charter, management of the Corporation is
responsible for the preparation, presentation and integrity of the Corporation's
financial statements,  and for the procedures designed to assure compliance with
accounting  standards  and  applicable  laws and  regulations.  The  independent
auditors are responsible for auditing the Corporation's financial statements and
expressing an opinion as to their conformity with generally accepted  accounting
principles.

     In performing  its oversight  function,  the Committee has  considered  and
discussed the audited  financial  statements with management and the independent
auditors.  The Committee has discussed with the independent auditors the matters
required  to  be  discussed  by   Statement  on  Auditing   Standards   No.  61,
COMMUNICATION WITH AUDIT COMMITTEES, as modified or supplemented.  The Committee
has also received the written disclosures from the independent auditors required
by Independence  Standards Board Standard No. 1,  INDEPENDENCE  DISCUSSIONS WITH
AUDIT COMMITTEES, as currently in effect.

     The members of the Audit  Committee are not  professionally  engaged in the
practice  of  auditing  or  accounting  and are not  experts  in the  fields  of
accounting or auditing, including the issue of auditor independence.  Members of
the Committee rely without independent  verification on the information provided
to them  and on the  representations  made  by  management  and the  independent
auditors.  Accordingly,  the Audit  Committee's  oversight  does not  provide an
independent  basis to  determine  that  management  has  maintained  appropriate
accounting and financial reporting  principles or appropriate  internal controls
and  procedures  designed to assure  compliance  with  accounting  standards and
applicable   laws  and   regulations.   Furthermore,   the   Audit   Committee's
considerations and discussions referred to above do not assure that the audit of
the Corporation's  financial  statements has been carried out in accordance with
generally  accepted  auditing  standards,  that  the  financial  statements  are
presented in accordance with generally  accepted  accounting  principles or that
the Corporation's auditors are in fact "independent."

                                      1-i




     Based upon the  reports  and  discussions  described  in this  report,  and
subject to the  limitations  on the role and  responsibilities  of the Committee
referred to above and in the charter,  the  Committee  recommended  to the Board
that the audited financial  statements be included in the  Corporation's  Annual
Report for the year ended December 31, 2002.

                        SUBMITTED BY THE AUDIT COMMITTEE
                     OF THE CORPORATION'S BOARD OF DIRECTORS
