OK, that's your agreement. You are bound by it's terms. Forget my comments.
Read the conditions carefully and thoroughly and avoid asking questions about isolated phrases that you pull out of the document.
You need to read those phrases in context with the entire agreement and you'll understand that, among the limitations, there are exceptions, contingencies and definitions.
For example, you asked what "contact" and "incidental contact" means.
Both are defined in paragraphs 3 and 4.
Paragraph 5 appears to imply that you cannot work at the swap meet without advance approval of your agent. Yes, the phrase swap meet is not in that paragraph but the phrase "included, but not limited to" means that anything related to the list is on the list. So, if you want to work at a swap meet, get approval in advance from your agent.
Bottom line, for sake of your own freedom, any questions about what you can and cannot do, or how you interpret anything in that agreement, should be addressed to your agent before you do anything.
