that:

1.   I have reviewed this report on Form N-CSR of Insured  Municipal Income Fund
     Inc.;

2.   Based on my knowledge, this report does not contain any untrue statement of
     a material  fact or omit to state a  material  fact  necessary  to make the
     statements made, in light of the circumstances  under which such statements
     were made,  not  misleading  with  respect  to the  period  covered by this
     report;

3.   Based on my  knowledge,  the  financial  statements,  and  other  financial
     information  included  in  this  report,  fairly  present  in all  material
     respects the financial  condition,  results of  operations,  changes in net
     assets, and cash flows (if the financial statements are required to include
     a statement  of cash flows) of the  registrant  as of, and for, the periods
     presented in this report;

4.   The  registrant's  other  certifying  officer(s) and I are  responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in  Rule  30a-3(c)  under  the  Investment  Company  Act of  1940)  for the
     registrant and have:

          (a)  Designed such disclosure controls and procedures,  or caused such
               disclosure  controls  and  procedures  to be  designed  under our
               supervision,  to ensure that material information relating to the
               registrant,  including  its  consolidated  subsidiaries,  is made
               known to us by others within those entities,  particularly during
               the period in which this report is being prepared;

          (b)  Evaluated  the  effectiveness  of  the  registrant's   disclosure
               controls  and   procedures  and  presented  in  this  report  our
               conclusions  about the  effectiveness of the disclosure  controls
               and  procedures,  as of a date within 90 days prior to the filing
               date of this report based on such evaluation; and

          (c)  Disclosed in this report any change in the registrant's  internal
               control  over  financial   reporting  that  occurred  during  the
               registrant's  most  recent  fiscal  half-year  (the  registrant's
               second fiscal half-year in the case of an annual report) that has
               materially  affected,  or  is  reasonably  likely  to  materially
               affect,   the   registrant's   internal  control  over  financial
               reporting; and

5.   The registrant's  other  certifying  officer(s) and I have disclosed to the
     registrant's  auditors and the audit committee of the registrant's board of
     directors (or persons performing the equivalent functions):

          (a)  All  significant  deficiencies  and  material  weaknesses  in the
               design or operation of internal control over financial  reporting
               which are reasonably  likely to adversely affect the registrant's
               ability  to record,  process,  summarize,  and  report  financial
               information; and

          (b)  Any fraud,  whether or not material,  that involves management or
               other employees who have a significant  role in the  registrant's
               internal control over financial reporting.
