Following the Exclusivity Period (and during the Exclusivity Period, with respect to Product SKU quantities in excess of the Exclusive Purchase Requirement in accordance with the preceding sentence), nothing in this Agreement shall prevent Customer or any of its Affiliates from manufacturing Product for itself, or having Product manufactured by a Third Party, including in amounts in addition to the Purchase Orders for Product issued to Manufacturer in accordance with this Agreement. For clarity and notwithstanding anything contained herein, nothing in this Section 2.1(e)(i) (A) is intended to be inconsistent with Section 2.4(e)(i) or to otherwise indicate that Customer is subject to any requirement to purchase Product under this Agreement or (B) is intended to prevent Customer from qualifying a back-up supplier for any Product during the Exclusivity Period. -14- Source: UPJOHN INC, 10-12G, 1/21/2020 (ii) Upon request by Manufacturer, which Manufacturer may make from time to time during the Term but not more than once during any quarter of a Fiscal Year, Customer shall provide to Manufacturer within thirty (30) days of such request a certification attesting to Customer's compliance with its Exclusive Purchase Requirement obligations pursuant to Section 2.1(e)(i) and signed by a representative of Customer with a title of Vice President or more senior. 2.2 Use of Facility, Equipment, Molds and Tooling. (a) Facilities. For each Product, Manufacturer shall perform all manufacturing activities and all storage activities at the Facilities set forth in the Facility Addendum applicable to such Product. Manufacturer may use any other facility for the manufacture and storage of Products if (i) such facility has been approved for such manufacture by all applicable Governmental Authorities and (ii) Manufacturer obtains Customer's prior written consent with respect to the use of such other facility as set forth in Section 4.3(a) (such approval not to be unreasonably withheld, conditioned or delayed). The Parties shall agree to either execute a new Facility Addendum or amend an existing Facility Addendum in order to include such facility. Manufacturer shall notify Customer of its intent to use any alternate facility as soon as reasonably practicable. (b) Purchase and Installation of Equipment, Dedicated Change Parts and Tooling.

If Customer makes such a request for additional equipment or capacity, then the Parties shall promptly meet and discuss Customer's request in good faith, including an appropriate allocation of costs between the Parties with respect thereto. 2.3 Capacity. Subject to Section 2.2(b), Manufacturer shall devote adequate manufacturing capacity to be capable of manufacturing and supplying Product to Customer in accordance with the provisions of this Agreement and the Facility Addenda.
