AutoCAD-based products released before AutoCAD 2007 did not support annotative objects. If you need to share drawing files created in AutoCAD 2007 or later with others using even earlier releases, you will need to save the drawing to the AutoCAD 2007/LT2007 file format and set SAVEFIDELITY to 1. This action preserves the visual fidelity of the annotative objects by saving individual representations of each scale of each annotative object. The individual objects are saved to layers that are used to organize objects of the same scale.
