 To prevent this, turn off the Exceed's "automatic font substitution"

+** Subscript/superscript text in TeX is hard to read.

+If `tex-fontify-script' is non-nil, tex-mode displays
+subscript/superscript text in the faces subscript/superscript, which
+are smaller than the normal font and lowered/raised.  With some fonts,
+nested superscripts (say) can be hard to read.  Switching to a
+different font, or changing your antialiasing setting (on an LCD
+screen), can both make the problem disappear.  Alternatively, customize
+the following variables: tex-font-script-display (how much to
+lower/raise); tex-suscript-height-ratio (how much smaller than
+normal); tex-suscript-height-minimum (minimum height).
