shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

Section 7.9 Remedies.

(a) Each party hereto acknowledges that monetary damages would not be an adequate remedy in the event that each and every one of the covenants or agreements in this Agreement are not performed in accordance with their terms, and it is therefore agreed that, in addition to and without limiting any other remedy or right it may have, the non-breaching party will have the right to an injunction, temporary restraining order or other equitable relief in any court of competent jurisdiction enjoining any such breach and enforcing specifically each and every one of the terms and provisions hereof.
