     Re: NOTICE OF INTENTION TO NOMINATE INDIVIDUALS FOR ELECTION AS TRUSTEES AT
         THE ANNUAL MEETING OF STOCKHOLDERS  OF PIONEER TAX ADVANTAGED  BALANCED
         TRUST.

Dear Sir or Madam:

      This letter  shall serve to satisfy the  advance  notice  requirements  of
Article III,  Section 7 of the Bylaws (the  "Bylaws") of Pioneer Tax  Advantaged
Balanced Trust ("PBF") as to the nomination by Western  Investment LLC ("Western
Investment" or the "Nominating  Stockholder") of three (3) nominees for election
to the Board of Trustees of PBF (the "PBF Board") at the 2007 annual  meeting of
stockholders of PBF, or any other meeting of stockholders  held in lieu thereof,
and any adjournments, postponements, reschedulings or continuations thereof (the
"Annual Meeting").

      This letter and all Exhibits attached hereto are collectively  referred to
as the "Notice." Western  Investment is the beneficial owner of 1,662,841 shares
of common  stock,  no par value (the "Common  Stock"),  of PBF,  1,000 shares of
which are held of record by Western  Investment.  Through this  Notice,  Western
Investment hereby nominates and notifies you of its intent to nominate Arthur D.
Lipson and Robert Ferguson (together,  the  "Common/Preferred  Shares Nominees")
and  Matthew  Crouse  (the  "Preferred  Shares  Nominee")  as  nominees  (each a
"Nominee" and collectively the "Nominees") to be elected to the PBF Board at the
Annual Meeting. The Nominating Stockholder believes that, of the three (3) Class
I Trustees  whose terms expire at the annual  meeting,  two (2) are eligible for
election by holders of shares of Common Stock and  preferred  stock  ("Preferred
Stock") of PBF, voting together as a class. The Common/Preferred Shares Nominees
are  being  nominated  for  election  as the two (2) Class I  Trustees  that are
eligible to be elected by holders of shares of Common Stock and Preferred Stock,
voting together as a class.  The Preferred Shares Nominee is being nominated for
election as the one (1) Class I Trustee eligible to be elected by the holders of
shares of  Preferred  Stock.  If in fact there are more than three (3)  trustees
eligible  for election or the above  beliefs are not  accurate,  the  Nominating
Stockholder  reserves the right to nominate such number of  additional  trustees
eligible for election at the Annual Meeting or to redesignate the Nominees named
herein  between the Preferred  Shares  Nominee and the  Common/Preferred  Shares
Nominees. Any additional nominations made pursuant to the preceding sentence are
without prejudice to the position of Western  Investment that any attempt by PBF
to increase  the size of the PBF board or to  reconstitute  or  reconfigure  the
classes  on which the  current  trustees  serve  would  constitute  an  unlawful

the Nominees at the Annual Meeting, or if any individual Nominee shall be unable

to the remaining  Nominee(s) and as to any  replacement  Nominee(s)  selected by

      NOW, IT IS AGREED, this 15th day of March 2007 by the parties hereto:

      1. In accordance with Rule 13d-1(k)(1)(iii)  under the Securities Exchange
Act of 1934, as amended,  each of the  undersigned  (collectively,  the "Group")

Investment's  prior written  approval;  (ii) the value of the time of any party;
(iii) legal fees incurred without Western  Investment's  prior written approval;
or (iv) the costs of any counsel, other than Olshan, employed in connection with

Nothing herein shall  restrict any party's right to purchase or sell  securities
of PBF, as he/she/it deems appropriate, in his/her/its sole discretion, provided
that all such sales are made in compliance with all applicable securities laws.
