I, Charles E. Porter, the Principal Executive Officer of the funds listed on

Attachment A, certify that:


1.  I have reviewed each report on Form N-Q of the funds listed on

Attachment A:


2.  Based on my knowledge, each report does not contain any untrue

statements 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

each report;


3.  Based on my knowledge, the schedules of investments included in each

report fairly present in all material respects the investments of the

registrant as of the end of the fiscal quarter for which the report is

filed;


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 registrants 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 each 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 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 registrant’s most recent

fiscal quarter 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 each

registrant’s auditors and the audit committee of each 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 each 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 each registrant’s internal control

over financial reporting.
