                       HENDERSON OPPORTUNITIES TRUST PLC

            Transactions in a Close Period - Listing Rule 15.5.1 (4)

Henderson Opportunities Trust plc ('the Company') hereby confirms that:

     
a)   there is no unpublished information which constitutes price sensitive
     information in respect of the Company's securities;

b)   the Company's net asset value per share is calculated and announced
     through a Regulated Information Service ('RIS') on a daily basis;

c)   the Company has no reason to believe that there will be any material
     difference between the net asset value announced on 30 April 2008 (as at 
     close of business on 29 April 2008) and the financial information to be 
     published in the preliminary announcement of its results for the half year 
     ended 30 April 2008;

d)   the Company has some investments that are no longer quoted, the directors' 
     valuations of which have been included in the net asset values published on 
     a daily basis; and

e)   no dividend will be declared at the end of the close period but this fact 
     is not expected to be price sensitive.

The Company is therefore exempt during the close period from the provisions of
the Model Code in respect of dealings by persons discharging managerial
responsibilities, purchases of its own securities and the sale of treasury
shares for cash or transfers.  If, in the period leading up to the preliminary
announcement of the results, the directors or the Company come into possession
of any inside information, this will be notified to a RIS before any such
transactions are undertaken.

The close period to which this notification relates is in respect of the
financial half year ended 30 April 2008.

                                    - ENDS -
