A year ago, First Bank acquired and perfected a security interest in John’s tractor to secure all existing and future obligations of John to First Bank. On May 1 of this year, Second Bank obtained a security interest in the same tractor and perfected that security interest by filing a financing statement. On May 5, Creditor got the sheriff to levy on the tractor pursuant to a writ of execution.

In which of the following scenarios in which First Bank makes a future advance will it NOT have priority over BOTH Second Bank and Creditor with respect to the future advance?

1. First Bank loans John $10,000 on June 6, without knowledge of either Second Bank’s security interest or Creditor’s lien.

2. First Bank loans John $10,000 on June 6, with full knowledge of both Second Bank’s security interest and Creditor’s lien.

3. First Bank loans John $10,000 on July 7, with knowledge of Creditor’s lien but without knowledge of Second Bank’s security interest.

4. First Bank loans John $10,000 on July 7, with knowledge of Second Bank’s security interest but without knowledge of Creditor’s lien.
