Any such contract shall provide that the agent shall be responsible to the State for the faithful and safe conduct of the services to be performed by it as registration agent, recording agent or cancellation agent, or services related thereto, for the fidelity and integrity of the officers and agents of such contracting institution performing the duties of a registration agent, recording agent or cancellation agent, or services related thereto, and for all loss or damage which may result from any failure of such officers or agents to discharge their duties and for any improper or incorrect discharge of those duties, and shall save the State free and harmless from any and all loss or damage occasioned by or incurred in the performance of such services.
