>> Broker will cooperate with and compensate, as stated below, NEFMLS brokers and any broker who reciprocates with NEFMLS. For finding a buyer ready, willing and able to purchase the Property, SELLER will pay BROKER, no later than the date of closing, a broker transaction fee of 5% of the Purchase Price, whether a buyer is secured by BROKER, SELLER, or any other person. BROKER agrees to offer cooperating broker compensation of: 2.5% of the Purchase Price to a single agent for a buyer; or 2.5% of the Purchase Price to a transaction broker for a buyer; or 1% of the Purchase Price to a non-representative broker.

>> If no cooperating broker compensation is offered, the Property cannot be placed in NEFMLS. SELLER hereby directs closing attorney/settlement agent to disburse at closing all compensation to brokers payable hereunder

So in this case, the seller's broker is entitled to 5%, of which 2.5% is required to be shared with a buyer's broker, if existent.

In the event that no buyer's broker exists... it would be a conversation with the seller's broker as to how to dispose of the 2.5% (refund to the deal, etc.).
