I don't like the sound of 'agreement'. If you, and most other native speakers such as myself, are just as confused, don't pick up any pen and sign!
Don't hesitate - in a business situation, and therefore one that may have a legally-binding outcome that renders you culpable with the sole defence of 'ignorance' - in contacting the person and requesting clarification.
** for anyone interested, why the use of the gerunds, and not, "Don't hesitate -.....- to contact.....and to request..."
