I, Timothy C. Maurer, Chief Financial Officer of Income Growth Management, Inc.,

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 small business

4. The small business issuer's other certifying officer(s) and I are 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

              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(s) 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.
