         1. I have reviewed this amendment to quarterly report on Form 10-QSB of
BF Acquisition Group IV, 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;

responsible for establishing and maintaining  disclosure controls and procedures
(as  defined  in  Exchange  Act Rules  13a-15(e)  and  15d-15(e))  for the small
business issuer 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 small business issuer,  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 small  business  issuer's  disclosure
     controls and procedures and presented in this report our conclusions  about
     the effectiveness of the disclosure controls and procedures,  as of the end
     of the period covered by this report based on such evaluation; and

(c)  Disclosed in this report any change in the small business issuer's internal
     control over financial  reporting  that occurred  during the small business
     issuer's most recent fiscal  quarter that has  materially  affected,  or is
     reasonably  likely  to  materially  affect,  the  small  business  issuer's
     internal control over financial reporting; and

         5. The small  business  issuer's  other  certifying  officer and I have
disclosed,  based  on our  most  recent  evaluation  of  internal  control  over
financial  reporting,  to the small  business  issuer's  auditors  and the audit
committee  of the  small  business  issuer'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 small business  issuer'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  small  business  issuer's
     internal-control over financial reporting.
