Sarah Connor owns a pest control business, The Terminatrix, which she operates as a sole proprietorship.  Arnold Financing Company loaned Sarah $5,000, to be repaid in a lump sum in six months, and secured by a security interest in all her equipment, including after-acquired.  Arnold Financing Company properly perfected its security interest by filing a proper financing statement.  Six months later, Sarah paid off her loan.  Which statement is correct?

1. Arnold Financing Company must immediately file a termination statement.

2. Arnold Financing Company must file a termination statement only if a third party asks it to do so

3. Arnold Financing Company must file a termination statement only if Sarah Connor asks it to do so

4. Arnold Financing Company need never have to file a termination statement because its UCC-1 will automatically lapse after five years.
