Item 4. Changes in Registrant's Certifying Accountant

  (a) Previous independent accountants

     (i)  On  October  27,  1998,  HERC  Products  Incorporated  ("Registrant"),
dismissed BDO Seidman, LLP as its independent accountants.

     (ii)  The  reports  of  BDO  Seidman,  LLP on  the  consolidated  financial
statements  for the past two  fiscal  years  contained  no  adverse  opinion  or
disclaimer of opinion but were modified as to uncertainty  regarding substantial
doubt about the ability of the Registrant to continue as a going concern.

     (iii) The Registrant's Board of Directors  participated in and approved the
decision to change independent accountants on October 27, 1998.

     (iv) In connection with its audits for the two most recent fiscal years and
through June 30, 1998, there have been no disagreements with BDO Seidman, LLP on
any  matter  of  accounting   principles  or  practices,   financial   statement
disclosure, or auditing scope or procedure,  which disagreements if not resolved
to the satisfaction of BDO Seidman, LLP would have caused them to make reference
thereto in their report on the consolidated financial statements for such years.

     (v) During the two most  recent  fiscal  years and through  June 30,  1998,
there  have  been no  reportable  events  (as  defined  in  Regulation  S-K Item
304(a)(1)(v)).

     (vi) The Registrant  has requested that BDO Seidman,  LLP furnish it with a
letter  addressed  to the SEC  stating  whether or not it agrees  with the above
statements.  A copy of such letter,  dated November 2, 1998, is filed as Exhibit
16.1 to this Form 8-K.

 (b) New independent accountants

     The  Registrant   engaged  Arthur  Andersen  LLP  as  its  new  independent
accountants as of October 27, 1998.  During the two most recent fiscal years and
through June 30, 1998, the  Registrant  has not consulted with Arthur  Andersen,
LLP regarding either (i) the application of accounting principles to a specified
transaction,  either  completed or proposed,  or the type of audit  opinion that
might be rendered on the Registrant's  consolidated  financial  statements,  and
either a written  report  was  provided  to the  Registrant  or oral  advice was
provided that Arthur Andersen,  LLP concluded was an important factor considered
by the  Registrant  in  reaching a decision  as to the  accounting,  auditing or
financial  reporting  issue; or (ii) any matter that was either the subject of a
disagreement,  as that term is defined in Item  304(a)(1)(iv)  of Regulation S-K
and the related  instructions  to Item 304 of  Regulation  S-K, or a  reportable
event, as that term is defined in Item 304(a)(1)(iv) of Regulation S-K.
