A licensee shall not solicit a written brokerage agreement from a seller or buyer if the licensee knows, or acting in a reasonable manner should have known, that the buyer or seller has contracted with another real estate brokerage agency for the same real estate brokerage services on an exclusive basis. This Section does not preclude a real estate brokerage agency from entering into a written brokerage agreement with a seller or buyer, when the initial contact is initiated by the seller or buyer, provided that the written brokerage agreement does not become effective until the expiration or release of the previous written brokerage agreement.
