Notwithstanding the foregoing, in the event the License Effective Date occurs under Section 3.2(d) due to an At-Risk Launch earlier than Impax’s requested delivery of Launch Quantities, the parties shall reasonably cooperate to supply Launch Quantities requested by Impax to enable Impax to launch Impax Authorized Generic Product

as soon as reasonably practicable following the License Effective Date under Section 3.2(d).

(d) [**] following the License Effective Date, and [**] thereafter beginning with the date [**] the License Effective Date, Impax shall deliver a forecast (a “Forecast”) to Eurand of the quantities of Impax Authorized Generic Product, by SKU, which Impax reasonably anticipates it will require for marketing [**] the License Effective Date in the first instance, and thereafter [**] the date of such Forecast and shall include quantities required to be delivered [**] of the Forecast Period.

Additionally, in each subsequent Forecast, the amount ordered for the Purchase Order Period shall not deviate [**] (as to the entire period or any month therein) from [**] of the immediately preceding Forecast. Other than the specifically provided in this paragraph, the amounts set forth in the Forecasts shall only constitute a non-binding estimate of the Impax Authorized Generic Product requirements.

(e) Eurand shall use commercially reasonable efforts to make deliveries of Impax Authorized Generic Product [**] of the agreed upon delivery dates, which delivery dates shall be at least [**] from the date a binding purchase order is received by Eurand.

Anesta will reasonably cooperate with Impax in timely making the appropriate regulatory filings.

(l) During the Term, and for a period of [**] thereafter, Eurand shall, and shall ensure that its Affiliates shall, keep at either its normal place of business, or at an off-site storage facility, detailed, accurate and up to date information and data contained in any invoices provided to Impax in connection with this Agreement.
