Attacking a grapple opponent?

[Solientious]

Does an attacker suffer a negative consequence for attacking a character that is being grappled? Does the attacker suffer a -4 to attack a creature ingauged in a grapple?

If the character forgoes the -4 penalty would they stand a chance of hitting the undesired person?

[Isaiah Overseas]

Implication is that they're actually easier to hit, -4 to Dex.
So RAW, no. no. and no.
