I need to count how many rows with specific criteria do not match the same criteria on another sheet.

Sheet 1 is on the left, sheet 2 is on the right.

Both sheets have 2 columns. I need to do a countif and vlook up combinaton of sorts. When the columns of both sheets are combined, I need to do a vlookup to see what from sheet 1 IS NOT FOUND in Sheet 2. In the attached screenshot here would be two instances of rows that did not match or were not found on sheet 2.

Can anyone assist?
