         Western  Investment  Hedged  Partners L.P.  ("Western  Investment")  is
filing materials contained in this Schedule 14A with the Securities and Exchange
Commission relating to a proxy statement and accompanying proxy cards to be used
in  connection  with the  special  meeting of  stockholders  of  Tri-Continental
Corporation  (the  "Company")  scheduled to be held on  September  28, 2006 (the
"Annual  Meeting")  to  solicit  votes in  support  of the  election  of Western
Investment's  slate of director  nominees and against  certain of the  Company's
proposals at the special meeting.

         Item 1: On or about  August 22,  2006,  Western  Investment  mailed the
following letter to stockholders of the Company:


                 VERY IMPORTANT VOTE: AN OPPORTUNITY TO RESTORE
                 TRI-CONTINENTAL'S PREMIER INVESTMENT REPUTATION

                                                                 August 22, 2006

Dear Stockholders of Tri-Continental Corporation:

         I write  to you as a fellow  investor  in  Tri-Continental.  We are all
interested in protecting our investment.  The proxy statement included with this
mailing sets forth the reasons why, on behalf of a group of concerned  long-term
Tri-Continental  stockholders,  we oppose both the director slate put forward by
the Company and the Company's proposal to amend its charter to reduce the quorum
requirement to one-third,  which would permit a small  minority of  stockholders
the ability to approve actions on behalf of all stockholders.  We have nominated
a slate of outstanding nominees as an alternative to management's slate.

         As you probably  know, at the 2006 Annual  Meeting  neither our nor the
Company's  nominees received enough votes to be elected.  We were upset to learn
that,   for  what  we  believe  to  be  no   compelling   reason,   the  current
Tri-Continental Board has decided to call an unnecessary Special Meeting for the
election of three directors. Tri-Continental has estimated that it will spend in
excess of  $1,400,000  of  stockholder  money on this  unnecessary  meeting  and
election.  The  Company's  action  has  compelled  us to offer  stockholders  an
alternative to its nominees.

         This election will likely affect the direction of  Tri-Continental  for
years to  come.  We have  proposed  a slate  of  three  outstanding  world-class
investors  as  nominees  for  election at the  Special  Meeting.  We believe the
election of our slate is in the best interests of all stockholders.

         We  believe   that  the  large   discount   to  net  asset  value  that
Tri-Continental's stock trades at is a reflection of investor disappointment and
lack of confidence in J. & W. Seligman & Co. Incorporated's management. Electing
our  highly  experienced  nominees,  with  proven  track  records  of success in
supervising the investment management process will, in our opinion, send a clear
message  that the  enormous  discount  to net asset  value is  unacceptable.  If
elected,  our nominees will, if necessary,  consider additional market purchases
or self-tenders to reduce the discount to below 5%.





         To assist you in evaluating the  candidates  for election,  we ask that
you consider the following  factors when deciding whom to support at the Special
Meeting.


                          WESTERN INVESTMENT'S NOMINEES

                                                                                 Relationship with

WILLIAM MORRIS    o  None, other than Tri-Continental and Seligman             Director/trustee of 24
                                                                               Seligman-managed funds

JOHN R. GALVIN    o  None,   other   than   serving   on  boards  of  other    Director/trustee of 24
                     Seligman-managed funds                                    Seligman-managed funds

ROBERT L. SHAFER  o  None,   other   than   serving   on  boards  of  other    Director/trustee of 24
                     Seligman-managed funds                                    Seligman-managed funds






         I am  gravely  concerned  by  Tri-Continental's  performance  under the
management  of Seligman and the  leadership of William  Morris,  the Chairman of
both  Tri-Continental  and  Seligman.  In  spite  of the  disappointing  returns
produced  over the past 15 years by  Seligman  and the legal  challenges  facing
Seligman due to the  investigation  of Seligman for apparent  fraudulent  market
timing  practices  - an  investigation  in which  William  Morris  is named as a
respondent  - and the  investigation  into  whether  Seligman  engaged  in fraud
relating to the advisory fees paid to it, the current  Tri-Continental Board has
consistently  voted to retain Seligman as  Tri-Continental's  investment manager
and approve the management fees payable to Seligman.

         The New York  Attorney  General  is  currently  investigating  apparent
fraudulent  conduct  involving  Seligman.  The  investigations  concern apparent
fraudulent market timing practices involving Seligman funds and whether Seligman
committed  fraud in respect of the advisory  fees and expenses it received  from
Seligman funds. The market timing  investigation  concerns  apparent  fraudulent
conduct in Seligman's  secret  arrangements  with certain  preferred  customers,
permitting these preferred  customers to engage in mutual fund timing activities
that negatively impacted the investment returns to long-term stockholders in the
Seligman funds  affected.  The New York Attorney  General has estimated that the
harm or "dilution" suffered by Seligman stockholders in the funds affected is in
excess of $80 million.

         IN LIGHT OF THESE  ALLEGATIONS  AGAINST SELIGMAN AND MR. MORRIS,  EVERY
STOCKHOLDER MUST QUESTION THE JUDGMENT AND INDEPENDENCE OF THE DIRECTORS WHO YET
AGAIN  NOMINATED MR. MORRIS FOR  REELECTION AS A DIRECTOR.  THE  TRI-CONTINENTAL
BOARD'S  FAILURE  TO DEMAND  THE  HIGHEST  STANDARDS  OF ETHICS  AND  INVESTMENT
PERFORMANCE  FROM  SELIGMAN  MAKES US WONDER HOW  COMMITTED IT IS TO  PROTECTING
STOCKHOLDERS.

         Your vote at the September 28, 2006 Special Meeting will decide whether
"business as usual" will  continue  under the  lackluster  and LEGALLY  TROUBLED
management of Seligman,  or if  stockholders  will issue a mandate for change by
electing our nominees to the  Tri-Continental  Board.  Please carefully read the
enclosed proxy  materials.  We urge you to sign,  date and return the GOLD proxy
today, voting to install three truly independent stockholder  representatives to
the  nine-member  board.  THE LATEST DATED PROXY YOU RETURN WILL BE THE ONLY ONE
COUNTED, SO EVEN IF YOU HAVE ALREADY VOTED, YOU HAVE EVERY LEGAL RIGHT TO CHANGE
YOUR VOTE AND SUPPORT OUR SLATE WITH THE ENCLOSED GOLD CARD. Thank you.

                                         Very truly yours,

                                         /s/ Arthur D. Lipson
