CHIEF FINANCIAL OFFICER
I, Ernst Lubke, certify that:

1. I have reviewed this quarterly report of Registrant; 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 Registrant as of, and for, the periods presented in
this report; 4. Registrant'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)) and internal control over
financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f))
for 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 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 principles; (c)
Evaluated the effectiveness of Registrant's disclosure controls and procedures
and presented in this report our 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
Registrant's internal control over financial reporting that occurred during
Registrant's most recent fiscal quarter (Registrant's fourth fiscal quarter in
the case of an annual report) that has materially affected, or is reasonably
likely to materially affect, Registrant's internal control over financial
reporting; and 5. Registrant's other certifying officer(s) and I have disclosed,
based on our most recent evaluation of internal control over financial
reporting, to Registrant's auditors and the audit committee of 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 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 Registrant's
internal control over financial reporting.
