5.5 Prospective Legal Events.

(c) The P. A. acknowledges that the provisions of this paragraph are necessary and reasonable in order to protect BRT in the conduct of its business, particularly in light of the difficultly in ascertaining damages in the event of a breach.

(d) If any court or tribunal of competent jurisdiction determines that the duration, geographical limit or any other aspect of the above restrictive covenants is unenforceable in accordance with its terms in a particular jurisdiction, such covenant shall not terminate; instead, such covenant shall be deemed amended to the extent required to render it valid and enforceable in such jurisdiction and such court or tribunal is hereby authorized and directed to amend the non-competition covenant contained herein only to the extent that such court or tribunal determines such an amendment is necessary to make it valid and enforceable in said jurisdiction (with as minimal a change from the covenant as drafted as is legally permissible).
