The delegate shall warrant that no person, sales agency or other organization has been employed or retained to solicit or secure the contract upon an agreement or understanding for a commission, percentage or brokerage, or contingent fee. Breach of such warranty shall give the agency or the Department the right to annul the contract without liability, or at their discretion, to deduct from, or otherwise recover, the full amount of such commission, percentage, brokerage, or contingent fee, or to seek such other remedies as legally may be available.
