WAIVER OF REQUIREMENT

FOR AFFIDAVIT OF EXTRAORDINARY CONDITION

It appears to the Secretary of State that an earlier effort to deliver this instrument and tender such taxes and fees was made in good faith on the file date stamped hereto. The Secretary of State has determined that an extraordinary condition (as reflected in the records of the Secretary of State) existed at such date and time and that such earlier effort was unsuccessful as a result of the existence of such extraordinary condition, and that such actual delivery and tender were made within a reasonable period (not to exceed two business days) after the cessation of such extraordinary condition. The Secretary of State hereby waives the requirement for an affidavit of extraordinary condition and establishes such date and time as the filing date of such instrument.
