Whenever a lease agreement containing such a special pledge is renewed under its terms for an additional term, such special pledge shall be deemed effective for such additional term without the necessity of a new pledge being made or a new lease agreement being entered into for that purpose, and the exercise of the option to renew shall be construed as a renewal also of the said special pledge; provided, that said special pledge shall be applicable only to the aforesaid pledged revenues that are received by such authorizing subdivision during the fiscal year for which the lease agreement is renewed. Each such special pledge that shall be so effected by renewal of said lease agreement for an additional term shall be deemed to relate to, and to have been made as of, the date on which such lease agreement was made and shall take precedence over any pledge of said pledged revenues which might be made by such authorizing subdivision and over any claim which might arise against the said pledged revenues between the date on which such lease agreement was made and the first day of the additional term for which such lease agreement shall be so renewed. Any pledge of revenues made by such authorizing subdivision as aforesaid under the provisions of any contract made by it subsequent to the date of the lease agreement containing such special pledge shall be subordinate to the special pledge contained in such lease agreement.
