Why does does the donation exclude Federal Contractors, you must affrim that you are not a Federal Contractor
Am only familiar with rules in Texas and one other state. There are a few grey areas but in general, candidate needs to avoid like the plague anything that smaks of vote or influence buying (unless you are Obama) or possible solicitation as a reward for prior or future favors - monetary or non-monetary. Texas has no problem with assessing and collecting large fines against the person who completes the paperwork.
