Not less than [**] prior to the Supply Commencement Date and Quarterly thereafter, SAVIENT shall provide to NOF a rolling [**] forecast, starting from the Supply Commencement Date, of its expected quarterly requirements for the Activated PEG (“Forecast”), the first [**] of which shall be binding (a “Firm Forecast”) and the last [**] of which shall be non-binding.

8.6

Effect of Termination on Additional Supply of Activated PEG. If NOF terminates this Agreement pursuant to Section 8.4 or if SAVIENT terminates this Agreement pursuant to Section 8.2 or Section 8.3, then NOF shall supply to SAVIENT such amounts of Activated PEG that SAVIENT shall order through the effective date of such termination in accordance with such Forecasts and Firm Forecasts as may be submitted according to the terms of this Agreement.
