It can contain office and contact information. 

This information is below the shared top border and contained in a 1x2 table set at 95% width.  To create a table click: Table-->Insert Table and choose # rows and columns, border size (if any), colors, width, etc.  To edit table once it is created, right mouse click inside table and select Table Properties.   To edit cell properties, right mouse click inside cell and select Cell Properties (for alignment).

We will create these tables without borders.  I've included them so that you can see the tables.
