14. Validity of a notice

Every notice filed under this Act shall be valid for a period of five years from the date of filing unless the period of validity is extended by the filing of a continuation statement.

Upon the expiration of the validity of a notice, the security interest perfected by such notice shall become invalid unless the security interest is perfected without the filing of a notice.

If the security interest becomes invalid upon the expiration of the validity of such notice it shall be deemed never to have been perfected against a prior or subsequent purchaser of a collateral for value.
