The par­ties acknowl­edge that dur­ing the nego­ti­a­tions, which pre­ced­ed this Agree­ment, each had the unlim­it­ed right and oppor­tu­ni­ty to make demands and pro­pos­als with respect to any sub­ject or mat­ter not removed by law from the area of col­lec­tive bar­gain­ing.  The under­stand­ings and agree­ments arrived at by the par­ties after the exer­cise of that right and oppor­tu­ni­ty are set forth in this Agreement.
