SET NULL VALUES WITH CONDITIONAL STATEMENT

Hi,

I wonder if anybody knows of the right conditional statement to be used in Raster Calculator to set to "Null" (NoData) the raster cells of Raster 1 that coincide (overlap) with cells in Raster 2.

Please see images:

Raster 1 in red
Raster 2 in blue

The areas in red that coincide with the areas in blue should become "Null". Using ArcView10

Many thanks
