In such instance, the parties will mutually agree on an alternative delivery date not to exceed [**] from the original acknowledgement date for any such deferred Purchase Orders. Any deferral of Purchase Orders in accordance with this Section 4.4 shall not constitute a breach of this Agreement by Catalent nor shall it absolve Supernus of its obligations in respect of the Firm Commitment.

4.5Supernus’ Modification or Cancellation of Purchase Orders.

A.The parties shall make commercially reasonable efforts to modify the delivery date or quantity of Product in a Purchase Order, upon Supernus’ request which such request shall be in the form of a written change order submitted to Catalent at least [**] in advance of the earliest Processing Date covered by such change order. Such change order shall be effective and binding against Catalent only upon the written approval of Catalent, and, notwithstanding any such written approval, Supernus shall remain responsible for the Firm Commitment.

B.If Supernus fails to place Purchase Orders sufficient to satisfy the Firm Commitment in Section 4.2, Firm orders will be rescheduled into the next calendar quarter.

4.6Unplanned Delay of Processing. Catalent shall use commercially reasonable efforts to deliver all requirements of Product as set forth in the Firm Commitment. Catalent shall provide Supernus with as much advance notice as practicable if Catalent determines that any Processing will be delayed for any reason.

5.1Batch Records and Data; Release. Unless otherwise agreed to by the parties during their ordinary course of dealings, after Catalent completes Processing of a Batch, Catalent shall provide Supernus with copies of Batch records executed. After Catalent completes Processing of a Batch, and upon confirmed agreement as provided by Supernus QA, Catalent shall also provide Supernus or its designee with Catalent’s issuance of a certificate of conformance for such Batch. Issuance of a certificate of conformance by Catalent constitutes release of the Batch by Catalent to Supernus. Supernus shall be responsible for final release of Product (including testing, at its cost) to the market.

5.2Testing; Rejection. No later than [**] days after Supernus or its designee’s receipt of the Batch (“Review Period”), Supernus shall notify Catalent whether the Batch conforms to the Specifications. Upon receipt of notice from Supernus that a Batch meets the Specifications, or upon failure of Supernus to respond by the end of the Review Period, the Batch shall be deemed accepted by the parties and Supernus shall have no right to reject such Batch. If Supernus timely notifies Catalent in writing (an “Exception Notice”) that a Batch does not conform to the Specifications or otherwise does not meet the warranty set forth in Section 12.1 (“Defective Product”), then Catalent shall conduct an appropriate investigation to determine the cause of any nonconformity. If Catalent determines that the cause of nonconformity is attributable to Catalent’s [**], or [**] (“Catalent Defective Processing”), then Section 5.4 shall apply. Where the cause of nonconformity cannot be determined or assigned, it shall be deemed [**].

5.3Discrepant Results. If the parties disagree as to whether Product is Defective Product and/or whether the cause of the nonconformity is Catalent Defective Processing, and this is not resolved within [**] of the Exception Notice date, the parties shall cause a mutually acceptable independent third party to review records, test data and to perform comparative tests and/or analyses on samples of the alleged Defective Product and its components, including Supernus-supplied Materials. The independent party’s results as to whether or not Product is Defective Product and the cause of any nonconformity shall be final and binding. Unless otherwise agreed by the parties in writing, the costs associated with such testing and review shall be borne by Catalent if Product is Defective Product attributable to Catalent Defective Processing, and by Supernus in all other circumstances.

5.4Defective Processing. As agreed upon by both parties, Catalent shall either (A) re-Process (or if re-Processing is not permissible under cGMPs, then replace) at Catalent’s cost another Batch of Product as a replacement for any Batch of Defective Product attributable to Catalent Defective Processing, and/or [**], using Supernus-supplied Materials provided at Catalent’s cost (subject to the cap in Section 14.1), or (B) credit any payment made by Supernus for such rejected Batch. For the avoidance of doubt, Supernus shall be liable to pay for either the [**] or the [**]. THE OBLIGATION OF CATALENT TO RE-PROCESS (OR REPLACE) DEFECTIVE PROCESSING IN ACCORDANCE WITH THE SPECIFICATIONS OR CREDIT PAYMENTS MADE BY SUPERNUS FOR DEFECTIVE PRODUCT ATTRIBUTABLE TO CATALENT DEFECTIVE PROCESSING SHALL BE [**] AND [**] UNDER THIS AGREEMENT FOR DEFECTIVE PRODUCT AND [**].

6.1Delivery. Catalent shall deliver [**] the Facility promptly following Catalent’s release of Product to Supernus. For clarity, Supernus shall do its own release to market. Catalent shall segregate and store all Product until tender of delivery. To the extent not already held by Supernus, title to Product shall transfer to Supernus upon Catalent’s tender of delivery. If Catalent provides storage services, title to such items shall pass to Supernus upon transfer to storage. Supernus shall qualify a minimum of one (1) carrier to ship Product and then designate the priority of such qualified carriers to Catalent. Catalent arranges shipping and performs loading and/or logistics services for Supernus at Supernus’ request, and this does not alter the terms and limitations set forth in this Section 6.1. Catalent shall not be responsible for Product in transit, including any cost of insurance or transport fee for Product, or any risk associated with transit or customs delays, storage, and handling.

Pursuant to this Quotation (“Quotation”), Catalent Pharma Solutions, LLC, with a business address at [**] (“Catalent”) will provide validation manufacturing and in process testing services for Supernus Pharmaceuticals (“Client”) for its drug Viloxazine [**] (“Product”) (the “Project”).

Catalent must receive this signed Quotation from Client to schedule the Project. The Project will begin once the fully-executed Quotation, Client-supplied Materials (as defined below), Product, and purchase order (if required) is received at Catalent. A signed, effective Quality Technical Agreement (“QTA”) between Client and Catalent is required prior to Initiation of any GMP activities.

Client will provide to Catalent, at Client’s cost, all samples, reference materials, API, Product, Comparator Drug, materials and other Project-specific supplies in quantities sufficient to meet the requirements necessary to perform this Project (“Client-supplied Materials”). The Client-supplied Materials should arrive at the Catalent facility with all proper documentation. Client shall retain title to the Client-supplied Materials at all times and shall bear the risk of loss thereof.

If agreed between the parties, Catalent will purchase other materials, including excipients, columns, and/or non-standard or special instrumentation and equipment, required solely for this Project and invoice Client at cost plus Catalent’s customary acquisition and handling costs (excluding comparator product, which will be under a separate Quotation). Pricing for the items listed above does not include incoming freight charges, associated shipping materials, insurance charges, taxes, customs, duty or VAT charges into the country of the receiving Catalent facility, and will be invoiced to Client once respective invoices are received by Catalent.

Prices are based on utilizing Catalent-approved suppliers for materials. If materials are required to be supplied by un-approved vendors, the Client may either supply the materials from a Client-approved vendor or Catalent will audit the vendor at the Client’s cost.

Any individual testing that does not meet specifications will be charged at the nominal fee for the analysis.

Client will provide all available Project-related safety documentation to be used for this Project. It is the responsibility of Client to inform Catalent of any additional hazard information as soon as it

becomes available. Client will provide Catalent with updated toxicology information regarding the Client-supplied Materials as it becomes available to Client.

Catalent will assess all vendor and Client Safety Data Sheets and all handling data for the samples and Client-supplied Materials associated with this Project per Catalent procedures under the following banding categories:

If at any time a material is classified with an OEL [**] and/or falls under the [**], the samples and Client-supplied Materials will require special handling precautions and will be subject to a hazardous material fee and a surcharge for all handling and testing directly associated with the samples and Client-supplied Materials.

Catalent will manufacture [**] or [**] that will be used in the making of [**]. These batches will serve as the process validation batches and will be commercially sellable material once all associated validation activities are completed. The raw materials that will be used in this manufacturing campaign will be taken from current inventory that Supernus has procured under approved QAR’s associated with QTE-SUP-15-3456.04. Catalent will support the in-process testing dictated by the batch record. Supernus will support any in process testing driven by the validation protocol and all finished product release testing. Catalent will write all validation protocols and their associated reports.

Based on Client’s request for proposal, Catalent proposes the following:

•Processing Time Assumptions:

•[**]

•[**]

•[**]

•[**]

*Validation finished goods are commercially sellable pending all required approvals for commercial launch.

Catalent will carry out the below analytical activities in support of the project.

The project will start once the fully executed proposal, materials and purchase order (if required) are received by Catalent.

It is assumed that Client will be providing any required standards to Catalent. Should Client request Catalent to source standards, the costs of the standards will be passed through to Client. For any standards that are not readily available, the Catalent/Client team will discuss and determine next

steps. Additional charges may apply depending on the availability and status (i.e., qualified as standard or not) of the materials.

It is assumed Catalent will use routine materials for analytical work to be performed. For any materials that are Client-specific, additional charges may apply depending on the availability and type of materials.

Based upon the method complexity, Catalent reserves the right to amend estimated costs. All release testing assumes one composite sample per batch. Raw material testing assumes one lot of each excipient. If there are additional lots of excipients, a QAR will be written to cover the cost of the testing. As for Apr and all raw materials, note that ID/release Is only acceptable for cGMP usage if they are delivered and have been fully tested by the Client or other third party and shipped with the manufacture certificate of analysis. If residual solvent testing is required, the raw material cGMP release testing cost will be increased

Catalent may revise the prices provided in this Quotation (i) if Client’s requirements or any Client-provided information is inaccurate or incomplete; (ii) if Client revises Catalent’s responsibilities or the Project specifications, instructions, procedures, assumptions, processes, test protocols, test methods or analytical requirements; (iii) for such other reasons set forth in this Quotation; or (iv) any unforeseen circumstances which affect the Project.

Any revision to this Quotation shall be set forth in a Catalent Quotation Amendment Record (“QAR”) signed by both parties. In addition, the prices provided in a Quotation are subject to annual review to address changes in inflation, increased overhead charges, and other commercially reasonable factors.

The following regulatory activities may apply to this Quotation and will be invoiced to Client per activity.

Catalent shall not be obligated to perform any services under this Project which would involve any countries that are targeted by the comprehensive sanctions, restrictions or embargoes administered by the United Nations, European Union, United Kingdom or United States.

Catalent will issue invoices for completed milestones. If a milestone includes multiple activities or batches, each activity and batch will be invoiced when completed along with any release testing costs that may be required. Stability storage and set costs are invoiced at the initiation of the Project and are non-refundable. Invoices should be emailed to Client at the invoicing address provided in writing by Client.

Payments for all invoices are due within [**] following the date of the invoice and are non-refundable. Notwithstanding any other provision of this Quotation, if at any time any payment is not

received by Catalent by its due date, then Catalent may, in addition to any other remedies available at equity or in law, (i) charge interest on the outstanding sum from the due date (both before and after any judgment) at [**] until paid in full (or, if less, the maximum amount permitted by Applicable Laws); (ii) suspend any further performance of the Project hereunder until such invoice is paid in full, without releasing Client from its obligations under this Quotation; (iii) require payment in advance before any further performance of the Project or making any further shipments hereunder; and/or (iv) terminate this Quotation, all without releasing Client from its obligations under this Quotation; and Client shall reimburse Catalent for all costs and expenses incurred and all non-cancellable commitments made under the Project. Failure to bill for interest due shall not be a waiver of Catalent’s right to charge interest.

Any applicable wire transfer fees must be included in the payment issued to Catalent.
