One unit (“Unit”) is one Product tablet. Unit Pricing does not include [**]. Unit Pricing also does not include any [**] other than as expressly set forth in the Specifications. Unit Prices are based on the assumptions as to manufacturing processes, storage conditions, etc., as reflected in the Specifications. Accordingly, Unit Prices are subject to adjustment upon mutual agreement of the parties in the event any such assumptions are revised by Client or modified in connection with the Validation Services performed on the Product.

*Pursuant to Section 7.2, Unit Price increases are effective as of the Re-Pricing Date on January 1 of each calendar year.

The parties anticipate that one Batch will represent approximately [**] tablets.

For Contract Year 1, the Minimum Requirement referenced above includes Product produced hereunder pursuant to the Validation Services and any other batches of Product intended for commercialization produced by Catalent prior to the Commencement Date.

Subject to adjustment as provided in this Attachment C, Client’s minimum annual spend commitment for each Contract Year (the “Minimum Annual Spend Commitment”) shall equal the sum of (a) the amount of Product actually purchased during such Contract Year multiplied by the Unit Price and (b) the Minimum Requirement shortfall for such Contract Year multiplied by the Minimum Requirement shortfall Unit Pricing set forth in the table above; provided, that, except as adjusted as provided in this Attachment C, the Minimum Annual Spend Commitment for any Contract Year shall in no event be greater than the Minimum Requirement for such Contract Year multiplied by the Unit Price.

All fees paid in full by Client by the invoice due date in accordance with the payment terms for services performed by Catalent (or its Affiliates) under (a) this Agreement, (b) the Master Services Agreement (Development and Manufacturing Services) between the parties dated July 6, 2007, as amended, (c) the Master Services Agreement (Labeling, Storage, Distribution, Return and Destruction Services) between the parties dated December 20, 2010, or (d) any other agreement, contract or understanding as documented by

written agreement between the parties (collectively, the “Annual Spend Amount”) shall be applied against the Minimum Annual Spend Commitment for the Contract Year in which the services were performed. Notwithstanding the foregoing, amounts paid for comparator products sourced by Catalent in connection with services performed by Catalent shall not be applied against any Minimum Annual Spend Commitment. For clarity, any services performed by Catalent (or its Affiliates) under any of the foregoing agreements, contracts or understandings as documented by written agreement between the parties which were ongoing as of January 1, 2018 or thereafter shall be included in the Annual Spend Amount.

The parties will use good faith efforts to agree in writing upon the Minimum Annual Spend Commitment and the Annual Spend Amount for each Contract Year within forty-five (45) days following such Contract Year. The Minimum Annual Spend Commitment for the subsequent Contract Year will be (a) increased by the amount by which such Annual Spend Amount is less than such Minimum Annual Spend Commitment or (b) decreased by the amount by which such Annual Spend Amount is more than such Minimum Annual Spend Commitment. Any amount by which the Annual Spend Amount is less than the Minimum Annual Spend Commitment for the final Contract Year shall be payable by Client to Catalent within thirty (30) days following the parties’ written agreement on such amount in accordance with this Attachment C.

Client agrees to use commercially reasonable efforts to engage Catalent (or its Affiliates) on various projects in a good faith effort to meet the Minimum Annual Spend Commitment for each Contract Year. Client agrees to engage Catalent (or its Affiliates) to perform at least one (1) oral formulation solubility screen (Optiform^® Solution Suite) within three (3) months of the Amendment 2 Effective Date, subject to the good faith negotiation of the terms and conditions with respect to the Optiform^® services.
