“The tort of negligent interference with prospective economic advantage is established where a plaintiff demonstrates that
(1) an economic relationship existed between the plaintiff and a third party which contained a reasonably probable future economic benefit or advantage to plaintiff;
(2) the defendant knew of the existence of the relationship and was aware or should have been aware that if it did not act with due care its actions would interfere with this relationship and cause plaintiff to lose in whole or in part the probable future economic benefit or advantage of the relationship;
(3) the defendant was negligent; and
(4) such negligence caused damage to plaintiff in that the relationship was actually interfered with or disrupted and plaintiff lost in whole or in part the economic benefits or advantage reasonably expected from the relationship.”
