Question on Confidentiality Agreement

[Nicholas Catanzariti]

Received a message from a real estate agent who has offered to supply me with some off market deals they come across.  Before provided me with listings they are requested that I sign and return a confidentiality agreement which states the following;

"The Premises is being offered to Potential Buyer as a Principal only and Potential Buyer or its’ agents acknowledge that it will not receive any brokerage commission from seller in connection with the purchase of the Premises"

Can someone clarify this statement for me?  What exactly does this mean?  I know I am the potential buyer and the Premises in the property being offered, but I am lost after that.
