I, David P. Marks, certify that:

1.       I have reviewed this report on Form N-CSR of Ultra Series Funds;

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 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) and
         internal control over financial reporting (as defined in Rule 30a-3(d)
         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)   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 principals;

         c)   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

         d)   Disclosed in this report any change in the registrant's internal
              control over financial reporting that occurred during the
              second fiscal quarter of the period covered by this 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 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.
