First Bank makes a loan to John Smith to enable him to open and operate a restaurant.  Smith signs a security agreement covering his present and after-acquired restaurant equipment, and First Bank files a financing statement covering the equipment on January 1, 2010. Smith begins acquiring items for the restaurant and begins operating.

Smith has also always longed to be a woman.   He legally changes his name to Jane Smith on January 1, 2011, but fails to notify First Bank.  Smith (as Jane) continues to purchase items for the restaurant.  The town where Smith lives is very conservative; people stop frequenting the restaurant and Doe eventually closes on January 1, 2012. First Bank never learned about the name change. In which of the following items does First Bank have an unperfected security interest?

1. Tables purchased on February 20th, 2010

2. A dishwashing machine purchased on November 12th, 2011

3. Bar equipment purchased February 28th, 2011

4. An oven purchased on January 12th, 2010
