What is the difference between indecent exposure and lewd conduct?

"The nature of the specific intent required for indecent exposure . . . is quite distinct from that involved in lewd conduct [ 647, subd. (a)]. A person who exposes his private parts with the intent 'to direct public attention to his genitals' is necessarily engaged in a purposeful and aggressive sexual display designed to provoke others. In contrast, lewd conduct can be committed by one who blithely ignores the risk of being seen and acts despite the presence of others, rather than because of it." (People v. Honan (2010) 186 Cal.App.4th 175, 182, original italics.)
