Transfer Plans. Alkermes shall create as needed process transfer plans ("Process Transfer Plan(s)") and work plans under the Development and Clinical Supply Agreement, which shall include activities necessary for the transfer, validation and commercial scale-up of the Commercial Product’s manufacturing processes within the Alkermes Facility.

Conduct. The Parties shall use Commercially Reasonable Efforts to conduct their activities under such Process Transfer Plan(s) and work plans. In performing their activities, the Parties shall act collaboratively, reasonably and in good faith with a view to timely achieving the aims of the Process Transfer Plan.

Inherent Uncertainties. The Parties acknowledge that there are inherent uncertainties involved in the scale up, transfer and manufacture of pharmaceutical products and that such uncertainties form part of the business risk involved in undertaking the form of commercial collaboration set out in this Agreement.

Project Managers. Each Party shall designate a "Project Manager" who shall be the principal point of contact between the Parties for all matters relating to process transfer, scale up and validation. A Party may designate a new Project Manager by written notice to the other Party.

Communications. The Project Managers shall communicate on a regular basis and make themselves reasonably available to each other for this purpose.

Supply Committee. After the Effective Date, the Parties shall establish a supply committee (the "Supply Committee"). The Supply Committee shall be comprised of a minimum of two (2) Alkermes employees and two (2) Zogenix employees having appropriate technical credentials, knowledge and experience, or such other number as the Parties may agree. Additional invitees may attend Supply Committee meetings upon the approval of both Alkermes and Zogenix.

General Remit. The Supply Committee shall serve as the coordinating body for the Manufacture and supply of Commercial Product under this Agreement. The Supply Committee shall also work to resolve any matter which arises between the Parties relating to the Manufacture and supply of Commercial Product under this Agreement. If the Parties are unable to resolve the matter through the Supply Committee, the Parties shall refer the matter to the committee organized and operating pursuant to Section 7.7.2 of the License Agreement, which is responsible for the overall development, regulatory and commercialization activities of Commercial Product under all of the Product agreements.

Meetings. The Supply Committee shall meet monthly by telephone or in person. Meeting agendas shall include as appropriate information on (a) anticipated market demand and inventory positions (including Compound inventory) and any material changes in market demand or inventory positions (including Compound inventory), (b) supply capability, (c) any capacity problems, unusual production situations, or prioritization issues, including pursuant to Clause 10.1, (d) any changes in Compound or Commercial Product delivery or sourcing, (e) any quality related issues, (f) any proposed amendments to Batch sizes based upon forecasted demand or changes in Product Specifications, (g) any forecast trends or proposed amendments to forecasts, and (h) any other matters which may impact or influence the Commercial Product supply chain.

Costs. Each Party shall be responsible for its own costs in respect of travel and accommodation expenses in attending such meetings.

Forecasts. Zogenix shall provide Alkermes with good faith, written, non-binding (subject to Clause 5.4.2 and 5.4.3) forecasts of its expected commercial requirements of the Commercial Product to be delivered as follows:

within [***] of the Effective Date, an [***] forecast, broken down on [***] basis, for the period beginning [***];

thereafter every [***] until [***], an updated forecast prepared on the same basis;

within [***], and thereafter every calendar month not later than the [***], a rolling eighteen (18) month forecast, broken down on [***] basis for the first [***] and [***] basis for the remaining [***], for the period commencing at the beginning of the following [***] in a form substantially similar to that which is mutually agreed by the Parties ("Forecast"); and

not later than [***], a [***] forecast, broken down on a [***] basis.

Additional Forecast for Procurement Quota. As a consequence of the restrictions currently imposed upon the importation, use and distribution of the Compound in and into the Territory, the Parties acknowledge the requirement to order the appropriate quantity of Compound in sufficient time to enable the supplier of the Compound to obtain the appropriate aggregate Procurement Quota for Manufacture.

Increased Capacity. If at any time after Commercial Product launch the Forecasts exceed Alkermes' then-current Manufacturing capacity, Alkermes and Zogenix shall meet and discuss in good faith ways in which additional Alkermes capacity may be secured to meet the Forecasts. If the additional capacity requires Alkermes capital expenditure, then the Parties shall negotiate (a) [***] which shall ensure the Commercially Reasonable utilisation of such capital equipment or (b) the [***], in each case, taking into account other products which could be manufactured on such equipment. For clarity, the maintenance of then-current Manufacturing capacity, even if the purchase of replacement capital equipment is required, shall be at Alkermes’ sole cost and expense.

Purchase Orders.

A "Purchase Order" is a binding order for such quantities of Commercial Product as is set out in the order. The Purchase Order shall include: (i) the quantity of Commercial Product to be delivered and (ii) the date on which the Commercial Product should be delivered and (iii) any other information reasonably requested by Alkermes. For clarity, once a Purchase Order has been accepted (a “Confirmed Order”), Zogenix shall be required to compensate Alkermes pursuant to the terms of this Agreement for any Commercial Product manufactured under such Confirmed Order, even if Zogenix or a Zogenix third party designee is unable to accept delivery of such Commercial Product because of insufficient Commercial Product Procurement Quota or lack of a valid DEA registration by Zogenix or Zogenix’s third party designee to receive such Commercial Product.

Validation batches that are manufactured for potential use as Commercial Product/Launch Stock shall be forecasted, ordered, delivered and paid pursuant to the terms of this Agreement. In conjunction with execution of this Agreement, Zogenix has submitted and Alkermes has accepted and confirmed a binding Purchase Order for validation batches that may be used as Commercial Product/Launch Stock which contains a delivery date that has been mutually agreed by the Parties. For other Launch Stock (if any), Zogenix shall submit a binding Purchase Order in which the date for delivery of the Commercial Product specified by Zogenix shall be not less than [***] following acceptance of such Purchase Order by Alkermes, taking into account Available Quota. On the first business day of each [***] after First Approval, Zogenix shall submit to Alkermes a Purchase Order for the quantity of Commercial Product specified in the first four (4) months of the last Forecast, less any Confirmed Orders or Launch Stock for delivery in that period. Unless otherwise agreed by Alkermes, the date for delivery of the Commercial Product specified by Zogenix shall be not less than four (4) months following acceptance of each Purchase Order by Alkermes.

Upon receipt of a Purchase Order Alkermes shall either accept or reject (to the extent entitled) the Purchase Order by written notification to Zogenix within [***] after receipt of the applicable Purchase Order. An accepted Purchase Order shall be a "Confirmed Order," subject to Alkermes’ ability to obtain sufficient Procurement Quota for Compound to Manufacture such Commercial Product.

Alkermes shall be entitled to reject any Purchase Order that does not conform to Clause 5.4.1 or that part of a Purchase Order that:

Exceeds in the aggregate (together with other Purchases Orders previously submitted) one hundred percent (100%) of the [***] requirement that was forecast by Zogenix for the [***] of delivery in the Forecast submitted [***];

exceeds the Available Quota;

exceeds (or in conjunction with Confirmed Orders in the relevant period exceeds) Alkermes's then-current maximum manufacturing capacity, which Alkermes shall have previously shared with Zogenix in a timely manner through the Supply Committee; or

requests partial Batches or less than a single Batch or where the total aggregate amount of Commercial Product ordered in a Purchase Order, when taken as a whole, does not [***].

The terms of this Agreement are hereby incorporated by reference into each Purchase Order submitted by Zogenix. No other terms or conditions, including any contained in a Purchase Order, shall apply to the sale and purchase of Commercial Product as between the Parties except pursuant to a modification duly executed as provided in this Agreement.

Safety Stocks. Zogenix shall use Commercially Reasonable Efforts to build during the first [***] and thereafter to maintain an inventory of Commercial Product [***] which is not less than the equivalent of the [***] ("Safety Stocks"), subject to Available Quota for the Commercial Product. Zogenix shall make Forecasts consistent with this requirement and will make good faith estimates of [***]. If requested by Zogenix, Alkermes and Zogenix shall discuss in good faith the ability of Alkermes or its Affiliates to hold Safety Stocks, the storage of such Safety Stocks being at [***].

Minima. Manufacture of validation batches and other Launch Stock shall be in Batch sizes of not less than the minimum quantities set out in Schedule 3 of this Agreement or in multiples thereof and the total aggregate amount of validation batches or other Launch Stock in a single Confirmed Order, when taken as a whole, must utilize [***]. Manufacture of Commercial Product shall be in Batch sizes of not less than the minimum quantities set out in Schedule 1 of this Agreement or in multiples thereof and the total aggregate amount of Commercial Product in a single Confirmed Order, when taken as a whole, must utilize [***]. The Parties shall discuss and agree other minimum Batch quantities as necessary through the Supply Committee.

Supply. Alkermes shall use Commercially Reasonable Efforts to supply the quantities of Commercial Product requested in each Confirmed Order.

Materials. Alkermes shall be responsible for procuring all Materials at its own cost; provided that:

in the event of (i) a change in the specifications for any Materials, or (ii) expiration or termination of this Agreement, Zogenix shall bear [***] last Forecast. Alkermes shall use Commercially Reasonable Efforts to mitigate such costs;

in the event that Compound that has been ordered and paid for, or must be paid for, by Alkermes pursuant to the Quota Forecast becomes obsolete for any reason (other than failure to meet

Packaging Materials. Zogenix shall be responsible for and shall supply Alkermes with all packaging artwork and inserts required for the Commercial Product. Except in reference to Alkermes trademarks reviewed and approved prior to their application, Zogenix shall indemnify Alkermes for any trademark, copyright or other content claims that may be made against Alkermes arising from such materials.

Supply Terms. Commercial Product supplied by Alkermes to Zogenix shall:

be delivered EXW the Alkermes Facility, except with respect to validation batches and Launch Stock which shall be delivered in accordance with Section 16.2;

be free from any liens, security interests or other encumbrances on title;

conform to Product Specifications and be manufactured in accordance with applicable cGMP and other applicable law;

have consumed no more than [***] with respect to Commercial Product that has [***] or, with respect to Commercial Product that has [***], have consumed no more than [***] provided however that (i) Zogenix may, at its option, accept Commercial Product with [***] and (ii) in circumstances where Zogenix decides to reject Commercial Product for not meeting [***] requirements, Zogenix will discuss its reasons in good faith with Alkermes through the Supply Committee. This provision shall not apply to validation batches/Launch Stock as provided in Section 16.2 of this Agreement or Commercial Product that is not released by Zogenix within the turnaround time that shall be agreed and defined in the Technical Agreement;

be packed in bottles in a packaging configuration provided by Zogenix and approved (or expected to be approved) by the FDA for Commercial Product that is ready for distribution in the Field in the Territory, or if agreed by Alkermes and Zogenix in writing, bulk packaged in a suitable manner for shipment;

be accompanied by a Certificate of Analysis for such Batch of Commercial Product; and

conform in all material respects with applicable provisions of the Technical Agreement with respect to Commercial Product.

Obsolete Commercial Product. In the event that Zogenix does not obtain sufficient Zogenix Commercial Product Procurement Quota or is otherwise unable to accept delivery of Commercial Product for which there is a Confirmed Order, then Alkermes shall be entitled to invoice and seek payment for such Commercial Product, including in-process Commercial Product, from Zogenix in accordance with Section 16 below.

Responsibility After Delivery. Title shall pass on delivery of Commercial Product to Zogenix. Zogenix shall be solely responsible for the storage, maintenance and transportation of Commercial Product from

Notification of Loss. Zogenix shall immediately notify Alkermes of the loss or damage of any Commercial Product in transit and/or shortfall in receipt before or after transit, and fully co-operate with Alkermes with respect to providing information to the DEA to support a notice of loss or theft and otherwise so as to enable Alkermes to comply with its obligations with regard to Controlled Substances. For clarity, this shall not affect the passage of risk of loss upon EXW delivery.

Modification of Product Specifications. Neither Party shall implement modifications to the Product Specifications without the other’s prior written request and approval. The Technical Agreement will contain processes for requesting and implementing changes to the Product Specifications.

Modification of Commercial Product Process. Zogenix shall have the right to review any proposed changes specific to Commercial Product manufacturing, testing or controls documentation in advance of their implementation, and shall have the right to approve any proposed changes which reasonably require either prior approval by any Governmental Authority or notice to any Governmental Authority. Any other changes that the Parties may agree require prior Zogenix approval and the review and approval process for any changes which require prior approval shall be set out in the Technical Agreement.

Change of Manufacturing Facility. Alkermes shall not change the Alkermes Facility from Gainesville (or other subsequent location) without Zogenix’s prior written consent, not to be unreasonably withheld or delayed. If Alkermes has requested a change of Alkermes Facility, Alkermes shall bear all costs and expenses associated with such change of Alkermes Facility, including costs associated with notice to and any approvals required from a Governmental Authority. This provision related to cost shall not apply where Zogenix has requested a change of Alkermes Facility, in which case it shall be at Zogenix’s cost, or the Parties otherwise mutually agree to change the Alkermes Facility, in which case the Parties shall allocate costs as mutually agreed.

Voluntary Second Source Option. If after receipt of the First Approval and if so requested in writing by Zogenix, Alkermes shall use Commercially Reasonable Efforts to enter into the relevant contracts and to validate a second manufacturing facility, which shall at Alkermes's option be another facility operated by Alkermes or its Affiliates, or a facility operated by a Third Party identified by Zogenix and agreed to by Alkermes (each, a "Second Facility"). Under no circumstances shall the owner of any such Second Facility be a Technological Competitor or be an Affiliate of a Technological Competitor without the prior written consent of Alkermes and provided further that Zogenix must take steps in all instances related to any Second Facility operated by a Third Party identified and/or used by Zogenix to ensure that Technological Competitors do not gain access, directly or indirectly, to Alkermes Confidential Information. Additionally, in the event that the Second Facility operated by a Third Party becomes a Technological Competitor, or an Affiliate of a Technological Competitor, the Second Facility must ensure that Alkermes Confidential Information and the manufacture of Commercial Product is “Contained Within a Ring Fence” as such phrase is defined in Section 16.3.2.1 of the License Agreement.

Voluntary Second Source Technology Transfer Plan. For this purpose and provided that Zogenix has exercised its right to validate a second manufacturing facility, Alkermes shall develop a plan of activities to enable the Second Facility to Manufacture and supply commercial quantities of Commercial Product to Zogenix in compliance with Product Specifications. Zogenix shall be responsible for the reasonable costs of all such activities, including all operator charges, Third Party expenses and the costs associated

Costs of Second Facility.

Zogenix shall be responsible for any costs associated with the scale up, validation and maintenance of any Second Facility and any equipment purchased by Second Facility to support and facilitate the Manufacture and supply of Commercial Product from the Second Facility; provided, however, Zogenix shall not be responsible for maintenance costs associated with unused capacity of any Alkermes-operated Second Facility in excess of amounts forecasted in the then-applicable Forecasts.

If Commercial Product is supplied from a Second Facility operated by a Third Party, Zogenix shall make compensating payments to Alkermes pursuant to Clause 16.5.

Where the Second Facility is operated by a Third Party:

in no event shall any supply by the Second Facility exceed (i) [***] of Zogenix’s total aggregate requirements of Commercial Product for any [***] and, only if and when applicable, (ii) additional amounts of Commercial Product that Zogenix is entitled to obtain from a Third Party manufacturer in accordance with Clause 10 of this Agreement;

any Third Party operator of the Second Facility (“Third Party Second Facility Operator”) shall directly invoice Zogenix for any Commercial Product Manufactured by the Third Party Second Facility Operator and Zogenix shall pay the Third Party Second Facility Operator for any such Commercial Product; and

Zogenix shall be solely responsible for organizing and fully reimbursing the Third Party Second Facility Operator for all Materials, equipment, licenses, and process and equipment validations required by applicable law or regulations for the Second Facility operated by a Third Party and for ensuring such Second Facility passes all inspections required to Manufacture and supply Commercial Product through the Second Facility.

Where the Second Facility is operated by Alkermes or an Alkermes Affiliate, Zogenix shall compensate Alkermes (or its Affiliate, as directed by Alkermes) for Commercial Product supplied at [***] and any other costs incurred by Alkermes or its Affiliate in accordance with the terms of this Agreement.

Notification of Failure to Supply. Subject to Zogenix keeping Alkermes informed as to their inventory position, if at any time during the Term, Alkermes anticipates that there will be a Failure to Supply, then Alkermes shall (a) give Zogenix prompt notice thereof and (b) use Commercially Reasonable Efforts to fulfil Purchase Orders with such quantities of Commercial Product as are available through itself on a timely basis.

Failure to Supply. In the event of a Failure to Supply and subject to the terms of this Clause 10, for so long as there is a Failure to Supply, Zogenix shall be entitled to obtain its requirements of Commercial Product from the Designated Manufacturer, as defined in Clause 9.1 of the License Agreement and pursuant to the provisions of the Manufacturing License granted to Zogenix in Clause 9 of the License Agreement. For clarity, the Third Party Second Facility Operator may be the Designated Manufacturer.

Supply Resumption. When Alkermes remedies the cause of the Failure to Supply and is once again able to fulfil Zogenix's Confirmed Orders, Alkermes shall so notify Zogenix (the "Resumption Notice") and Zogenix shall cease, or procure that the Designated Manufacturer ceases, Manufacturing the

Responsibility. In manufacturing the Commercial Product pursuant to the Manufacturing License, as between Alkermes and Zogenix, Zogenix shall be solely responsible for all costs, Procurement Quotas for Compound and Commercial Product, licenses, process and equipment validation required by applicable law or regulations for a Designated Manufacturer which is a Third Party and shall, subject to Alkermes obligations set forth in Clause 10.5, take all steps reasonably necessary to enable a Designated Manufacturer which is a Third Party to Manufacture Commercial Product.

Technology Transfer. In the event of (a) a Failure to Supply or (b) where the circumstances set forth in Clause 12.3.2, 12.3.3 or 12.3.4 of the License Agreement apply to Alkermes but Zogenix does not terminate this Agreement, Zogenix may notify Alkermes that it wishes to effect a technology transfer. Upon receipt of such notice (and as previously set out in the License Agreement in Clause 9.4), Alkermes shall:

provide Zogenix with any technical data incorporated in the Elan Know-How, including access to the CMC Section to give effect to the provisions of Clause 9.1 of the License Agreement and Alkermes shall promptly provide to Zogenix the documentation constituting the required material support, more particularly practical performance and advice, shop practice, specifications as to materials to be used and control methods; and

assist Zogenix for a period of [***] with the working up and use of the technology and with the training of Zogenix personnel which may be reasonably necessary in relation to the exercise of the Manufacturing License, including receiving Zogenix representatives in its or its Affiliates’ premises for limited periods as may be agreed upon by the Parties.

Sole Remedy For Failure to Supply. This Clause 10 and also Clauses 12.3.1 and 13.2.5 of the License Agreement solely to the extent that Alkermes is found to have materially breached Section 9.4 of the License Agreement set out Zogenix's sole and exclusive remedies in respect of Failure to Supply Commercial Product.

Alkermes shall conduct stability testing of Commercial Product as may be required by the Regulatory Approval on the Commercial Product or cGMP, at Alkermes’ sole cost and expense. Zogenix shall reimburse Alkermes for any additional stability testing requested by Zogenix at Alkermes’ then-current standard pull rates, currently [***]. For clarity, expenses related to stability testing of process validation lots will be governed by the Process Transfer Plan, as set forth in Clause 16.1.

Acceptance Procedures. Zogenix shall determine suitability for acceptance and release of Commercial Product for commercial distribution. If the Parties agree to additional acceptance procedures in the Technical Agreement, Alkermes shall use reasonable efforts to support transfer of any or all commercial methods to a third party laboratory and to provide test samples of any lot of Commercial Product when requested in order to establish acceptance testing ability.

Deficiency Notice. If Zogenix determines that the Commercial Product deviates from the Product Specifications or there are other material defects in Manufacturing that make such Commercial Product unsalable (a "Deviation"), Zogenix shall give Alkermes written notice (a "Deficiency Notice") outlining the Deviation, including such other information reasonably necessary to identify the Deviation, within [***]. Should Zogenix fail to provide Alkermes with a Deficiency Notice within the relevant and applicable time periods set out earlier in this paragraph, then delivery will be deemed to have been accepted by Zogenix, and Alkermes will have no liability for any Deviations for which it has not received notice within the applicable period.

Counter Notice. Within [***], Alkermes may provide written notice to Zogenix (a "Deficiency Counter Notice") that it contests the existence of a Deviation.

Dispute Resolution. In the event of an unresolved dispute as to the conformity of Commercial Product with Product Specifications, the Parties shall appoint an independent testing laboratory, acceptable to both Parties and subject to the confidentiality agreements herein, to undertake the relevant analysis, which analysis shall be performed in compliance with the applicable laws of the relevant regulatory Governmental Authority, to determine whether the Commercial Product conformed or did not conform to the Product Specifications. The test results obtained from such laboratory shall be conclusive and binding upon the Parties except in the case of fraud or manifest error. The fees and expenses of such testing shall be borne by Alkermes if it is ultimately determined that the Commercial Product failed to meet Product Specifications, or Zogenix in other cases.

Right to Reject. Where Alkermes does not provide a Deficiency Counter Notice in response to a Deficiency Notice alleging a Deviation, or where a dispute is resolved in Zogenix's favour pursuant to Clause 12.4 or by written agreement of the Parties, the Commercial Product in question shall be deemed rejected.

No Effect on Remainder of Delivery. No Deviation shall affect the delivery of any conforming part of the delivery.

Remedy. In respect of Commercial Product properly rejected and agreed, Alkermes shall Manufacture and deliver replacement Commercial Product as soon as practicable, but in any event within [***], subject to the availability of Materials, available Manufacturing capacity and Available Quota. Alkermes shall be responsible for its own costs of doing so, including the cost of the Materials and costs associated with the Manufacture and supply of replacement of such Commercial Product to Zogenix (including reasonable Third Party costs incurred by Zogenix in connection with Zogenix receiving such replacement Commercial Product) and, for clarity, Zogenix shall not pay an Initial Fee or Final Fee with respect to any properly rejected Commercial Product until such time as Zogenix accepts the

Adverse Events and Safety Reporting. Each Party shall, in accordance with the timing and procedures set forth in the Technical Agreement, give the other Party written notice of:

any matter arising out of this Agreement that must be reported by such other Party to a regulatory Governmental Authority;

any complaint about the quality or safety of Commercial Product supplied by Alkermes or which may reasonably affect the other Party's activities under this Agreement;

Zogenix's Discretion to Recall. If either Party is notified by a Governmental Authority that a recall, market withdrawal, stock recovery or other corrective action related to Commercial Product in the Territory (collectively a “Recall”) is required, requested or otherwise advisable, it shall promptly notify the other Party in writing of such notification. In circumstance where such a notification has been made or, alternatively if Zogenix establishes a need to conduct a Recall, Zogenix shall have sole discretion (except where required to take an action by Governmental Authorities) over whether and under what circumstances to require a Recall. Zogenix shall be responsible for coordinating Recalls and for ensuring that such activities are conducted in a commercially reasonable manner and Alkermes shall afford Zogenix reasonable assistance in conducting any such activities.

Recall Costs.

Except as provided in Section 13.3.2, Zogenix shall bear all costs of any Recall. Alkermes shall not invoice Zogenix for the cost of any internal Alkermes activities associated with such Recall but shall be entitled to invoice Zogenix for all other reasonable costs.

In circumstances where:

Commercial Product Recall arises from (a) Alkermes failure (or its Affiliate’s failure) to supply Commercial Product in accordance with Product Specifications and cGMP, (b) the negligent acts or omissions of Alkermes (or its Affiliate) in Manufacturing the Commercial Product or (c) from Alkermes breach of this Agreement, including without limitation Clause 7.4 with respect to such Commercial Product; and also that

Zogenix could not have discovered such failure or acts or omissions prior to the sale of such Commercial Product by exercising reasonable diligence;

Alkermes. As provided in Clause 6.1 of the License Agreement, Alkermes shall own, and shall be responsible at its own expense, for filing for and maintaining all necessary approvals to operate the Alkermes Facility as a cGMP manufacturing site.

DMF. In accordance with Clauses 6.1 and 6.6 of the License Agreement, Alkermes owns and shall be responsible, at its own expense, for filing and for maintaining the DMF. Pursuant to Clause 6.5 of the License Agreement, Alkermes has granted to Zogenix reference rights under such DMF in respect of Regulatory Applications in the Territory.

Zogenix. Except as provided in Clauses 14.1 and 14.2 of this Agreement and as provided in Clause 6.2 of the License Agreement, Zogenix shall own and shall be responsible for filing for and maintaining all necessary Regulatory Approvals in the Territory in respect of the Commercial Product and Zogenix shall provide Alkermes access to and use of such materials in accordance with Clause 6.6 of the License Agreement.

Cooperation. Clause 6.3 of the License Agreement is hereby incorporated in its entirety by this reference.

Governmental Inspection. Each Party shall notify the other Party as soon as practicable of any notification received from the FDA in connection with conduct of a cGMP inspection of facilities in relation to the Commercial Product. Each Party shall promptly provide to the other Party copies of all correspondence with the FDA related to the Manufacture or supply of Commercial Product in the Territory.

Right to Inspect. Alkermes shall procure that such portion of the facility where the Commercial Product is manufactured, tested or stored by or on behalf of Alkermes, including all record and reference samples, are made available for inspection:

by Zogenix's duly qualified employees upon reasonable notice or, alternatively, by an agent or consultant (who has been retained by Zogenix to conduct such activity) upon reasonable notice, provided however that any such agent or consultant is bound by written confidentiality provisions no less strict that those set out herein. Zogenix may exercise its rights under this Clause 14.6.1 to inspect the Alkermes Facility once in any calendar year utilising no more than two (2) inspectors during a single visit or on a “for cause” basis to investigate or resolve specific issues relating to the Manufacture of the Commercial Product at the Alkermes Facility; or

by the relevant Governmental Authority.

Cure of Deficiencies. Each Party shall be responsible for correcting any deficiencies associated with the activities for which it is responsible under this Agreement or the License Agreement and identified by the FDA in the course of any inspection or audit.

Process Transfer Plan Activities. Zogenix shall compensate Alkermes for the costs of the activities specified in the Process Transfer Plan and all other activities directed to scale-up, optimisation, and

Manufacturing – Validation Batches and Launch Stocks. Alkermes shall be entitled to partially invoice Zogenix for any validation batches or other Launch Stock ordered by Zogenix pursuant to a Confirmed Order that is manufactured and held in bulk capsule form by Alkermes prior to First Approval. Partial payments shall be invoiced at the time Alkermes delivers to Zogenix an appropriate Certificate of Analysis for such validation batch/other Launch Stock (which establishes that the validation batch/other Launch Stock have been manufactured and are being held by Alkermes in bulk form). These partial payment fees shall be invoiced per item of validation batch/other Launch Stock as set out in Schedule 3. Partial payments made on validation batches/other Launch Stock invoices shall be [***] irrespective of whether or when such the validation batch/other Launch Stock is delivered to Zogenix. The Parties shall also conduct a True-Up on all validation batches/other Launch Stock delivered before or at the time of launch to [***] as set forth in Clause 16.4 below (which, for clarity, shall be equivalent to [***] with the initial fee referred to in that section being equal to the partial payment set forth above in this paragraph. In circumstances where Commercial Product is not delivered or the validation batches/other Launch Stock becomes obsolete prior to the time that any Regulatory Approval is obtained in the Territory to facilitate delivery, the partial payment set out above in this paragraph shall be deemed the price of such validation batch/other Launch Stock, and no further payment shall be due. For clarity, validation batches/other Launch Stock with [***] at the time of First Approval may be deemed obsolete by Zogenix.

Manufacturing – Initial Fee for Commercial Product other than Validation Batches and Launch Stock. [***] after the delivery of Commercial Product (other than validation batches/other Launch Stock) which meets the requirements of Clause 7.4 or which Zogenix nonetheless accepts for delivery, Zogenix shall pay Alkermes the initial fee for such delivery, being [***] in effect during the [***] of scheduled delivery multiplied [***] (the "Initial Fee").

Final Fee True-Up. Upon provision of the Statement referred to in Clause 11.1 of the License Agreement, Zogenix shall additionally deliver to Alkermes a statement setting out (i) [***] ("Final Fee"), and:
