Company (the "Company");

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  circumstances under which such statements were
made, not misleading with respect to the period covered by this report; and

information included  in this quarterly report,  fairly present in all material
respects the financial condition, results of operations  and  cash flows of the
Company as of, and for, the periods presented in this report.

4.  I am  responsible  for establishing and maintaining disclosure controls and
procedures (as defined  in  Exchange  Act  Rules  13a-15(e)  and 15d-15(e)) and
internal control over financial reporting (as  defined  in  Exchange  Act Rules
13a-15(f) and 15d-15(f)) 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  Company,  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) Designed such  internal control  over financial  reporting, or  caused  such
internal control over financial reporting to be designed under our supervision,
to   provide  reasonable  assurance  regarding  the  reliability  of  financial
reporting and the preparation of financial  statements for external purposes in
 accordance with generally accepted accounting principles;

affect, the Company's internal control over financial reporting; and

5. I have disclosed,based on my most recent evaluation of internal control over
financial reporting, to  the Company's auditors  and  the  audit  committee  of
Company's  board of directors (or persons performing the equivalent functions);

a) all significant deficiencies in the design or operation of internal controls
which  could  adversely  affect  the  Company's  ability  to  record,  process,
summarize  and  report  financial  data  and have identified for the  Company's
auditors any material weaknesses in internal controls; and

b)  any  fraud,  whether or not material, that  involves  management  or  other
employees who have  a  significant role in the Company's internal controls over
financial reporting.
