martial present at the time the vote is taken of an offense in this 
chapter expressly made punishable by death.
    ``(c) If the trial counsel at a court-martial of an offense under 
this chapter expressly made punishable by death intends to prove at the 
trial any aggravating factor set out in subsection (e), the trial 
counsel shall provide the accused before arraignment with written 
notice of each such aggravating factor the trial counsel intends to 
prove. However, failure to provide such notice of an aggravating factor 
set out in subsection (e) before arraignment shall not bar later notice 
and proof of that aggravating factor unless the accused demonstrates--

Requires that any aggravating factors found be announced by the military judge upon determination of the death sentence.
