CERTIFICATION





EXHIBIT

I, Roger Tannery, certify
that:





1.           I
have reviewed this quarterly report on Form 10-Q of American Development &
Investment 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 and cash flows of the issuer 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)) for the
issuer and have:





a)  Designed
such disclosure controls and procedures, or caused such disclosure controls and
procedures to be designed under my supervision, to ensure that material
information relating to the small business issuer, including its consolidated
subsidiaries, is made known to me 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;





c)  Evaluated
the effectiveness of the small business issuer's disclosure controls and
procedures and presented in this report my 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





d)  Disclosed
in this report any change in the small business issuer internal control over
financial reporting that occurred during the small business issuers most recent
fiscal quarter (the small business issuers fourth fiscal quarter in the case of
an annual report) that has materially affected, or is reasonably likely to
materially affect, the small business issuers internal control over financial
reporting; and





5.           I
have disclosed, based on my 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 issuers 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.
