R.I. Gen. Laws § 7-11-802: Contract provisions.

(a) No person subject to this chapter who makes or engages in the performance of a contract in violation of this chapter or a rule or order of the director under this chapter, or who acquires a right under a contract with knowledge of the facts by which its making or performance is in violation, may obtain relief on the contract.

(b) A provision in a contract entered into or effective in this state, binding a person acquiring a security to waive compliance with this chapter or a rule or order of the chapter under this chapter is nonenforceable. A provision in a contract containing an agreement to arbitrate or a choice of law provision in a contract between persons all of whom are engaged in the securities business is not a provision waiving compliance with this chapter and is enforceable in accordance with its terms.
