can the Seller without paying realtor commision

[Ben C]

Hi,

We come across the property when visiting a friend's community. the seller's agreement with Realtor ended on May 8th and is preparing to list with another agent. one part of the contract says:

"If the property is sold within 90 days of the expiration or termination of this Agreement (which shall be the
"protection period") to a Buyer to whom the property was shown by Owner, Broker, another broker, or any other person or firm during the term of this Agreement, Broker's full fee shall be payable by Owner. The protection period shall be terminated if Owner enters into a listing agreement with another broker during the protection period."

since we meet after the contract expiration date. is the protection period still valid ?

Thanks

Ben
