The MSC may advise on any required modifications to this Agreement, but the decisions of the MSC shall not have any capacity to modify the terms of this Agreement unless mutually agreed to by the parties and documented by a signed amendment to this Agreement.

MannKind shall provide United Therapeutics an estimated Annual Budget by October 1 of each year for the following calendar year, based on the Rolling Forecast current as of September 1 of the year in which the Annual Budget is provided. Upon finalization of MannKind’s operating budget for the following calendar year, MannKind will provide United Therapeutics with any significant updates to the Annual Budget.

Facility Use, Capital Improvements, and Capacity Obligations.

Except as specifically authorized by this Agreement, MannKind shall Manufacture all Product and Semi-Finished Product at the Facility. MannKind shall not delegate nor subcontract any or all of its Manufacturing and Supply obligations under this Agreement to any Third Party other than Approved Suppliers without the prior written consent of United Therapeutics. The applicable requirements set forth or referenced in the Quality Agreement shall in all cases apply to Manufacturing by Third Parties. Approved Third Party Manufacturing Services providers are listed in Appendix D, for the specific services as stated.

MannKind currently operates at the Facility one dedicated automated powder filling/blister pack line capable of producing up to [***] cartridges annually (the “Existing Line”), one dedicated spray dryer capable of producing bulk drug product powder in adequate quantities to support the Existing Line (the “Existing Spray Dryer”), and a shared cold storage (2-8℃) with at least [***] pallet locations reserved for United Therapeutics’ use (the “Existing Cold Storage”) (collectively, the Existing Line, the Existing Spray Dryer, and the Existing Cold Storage, the “Existing Equipment”).

MannKind and United Therapeutics are parties to a letter agreement dated May 14, 2021, that amended the Development Plan and Budget as those terms are defined under the License Agreement, to provide for procurement by MannKind of additional capital equipment needed to enable the Manufacture and Supply of Product and Semi-Finished Product as provided for by this Agreement (such letter agreement, the “Cap-Ex Letter Agreement”; such additional capital equipment to be procured under the Cap-Ex Letter Agreement, the “Expansion Equipment”). Under the terms of the Cap-Ex Letter Agreement, United Therapeutics will fully fund the purchase of the Expansion Equipment, and such Expansion Equipment will be titled in United Therapeutics’ name. The parties hereby incorporate all of the terms of the Cap-Ex Letter Agreement into this Agreement, including without limitation, all rights and obligations related to the Expansion Equipment. MannKind shall reserve adequate space and resources in the Facility for the installation and operation of the Expansion Equipment.

MannKind will use the Existing Equipment and the Expansion Equipment solely for Manufacture and Supply of Product and Semi-Finished Product, and, pursuant to the Clinical Supply Agreement or other written agreement between MannKind and United Therapeutics Corporation, Pre-Commercial Product.  Upon installation and commissioning of the Expansion Equipment, MannKind shall be free to use the Existing Equipment for other purposes if demand for Product and Semi-Finished Product can be satisfied by the Expansion Equipment, taking into account any requirements for backup supply of Product as set forth in the Business Continuity Plan, provided that MannKind shall not be entitled to use components of the Existing Equipment paid for by United Therapeutics (i.e., the 50 liter collection vessel) for any use other than for United Therapeutics’ benefit. Following termination or expiration of this Agreement, MannKind shall deliver and/or dispose of the Expansion Equipment in accordance with United Therapeutics’ instructions, at United Therapeutics’ expense.

Upon United Therapeutics’ request, MannKind shall provide office space free of charge for up to two United Therapeutics employees at the Facility to provide coordination between the parties, facilitate issue resolution and conduct batch release.

MannKind shall use Commercially Reasonable Efforts throughout the Term, to identify potential investments in and improvements to the Facility, the Manufacturing process, and Facility staffing arrangements, including without limitation staffing arrangements reimbursed by United Therapeutics according to Appendix E, to enable improved cost efficiencies for the Manufacturing and Supply of Product and Semi-Finished Product, and MannKind shall notify United Therapeutics through the MSC upon identifying such potential investments and improvements, and shall reasonably cooperate with United Therapeutics to assess the merits of implementing such investments and improvements. If the parties mutually agree to proceed with an identified investment or improvement, the parties shall reasonably negotiate a shared burden of implementation cost, and shared benefit of cost savings resulting from, such investments and improvements, and shall reasonably cooperate throughout the implementation process.

Supply Obligations.

Subject to the terms and conditions of this Agreement, MannKind shall Manufacture the minimum quantities established through the Rolling Forecast and Supply Product and Semi-Finished Product to United Therapeutics or its designee, in the quantities specified in the Purchase Order, Firm Order, and Shipment Order processes described in sections 2.4, 2.5, and 2.6 below, at the applicable Prices, and in accordance with the applicable Product Specifications and/or Semi-Finished Product Specifications, and the Quality Agreement, for commercial distribution and sale by United Therapeutics or its agents.

United Therapeutics shall supply API to MannKind in quantities necessary to enable Manufacture of Product and Semi-Finished Product as required by this Agreement, in accordance with the specifications for API set forth in or referenced in the Quality Agreement, at United Therapeutics’ expense. MannKind shall place orders for API with

sufficient lead time, based on the minimum Product and Semi-Finished Product quantities specified in the Rolling Forecast. MannKind shall not sell, transfer, disclose or otherwise provide access to the API to any Third Party except to Third Party Manufacturing Services providers listed in Appendix D, as necessary for such Third Party Manufacturing Service provider to complete its Manufacturing obligations. Following termination or expiration of this Agreement for any reason, MannKind shall return any unused API to United Therapeutics, or destroy or reallocate such API for other use in accordance with Applicable Laws, as directed by United Therapeutics. Notwithstanding any physical transfer of API to MannKind, title to API shall at all times remain with United Therapeutics.

Rolling Forecast.

Within 10 business days following execution of this Agreement, United Therapeutics shall submit to MannKind an 18-month forecast for Product and Semi-Finished Product for the period commencing on the anticipated approval date. Such forecast shall be updated by United Therapeutics within the first 10 business days of each month during the Term. Such forecast, as updated on a monthly basis, shall be referred to as the “Rolling Forecast” throughout this Agreement.  Subject to the limitations and requirements set forth in section 2.4.2 below, the full 18 months of the initial Rolling Forecast shall be binding on the parties (i.e., United Therapeutics shall place Purchase Orders for, and MannKind shall Supply, not less than the minimum quantity of Product and Semi-Finished Product specified in such Rolling Forecast). Upon passage of the first 18 months of the initial Rolling Forecast, subject to the limitations and requirements set forth in section 2.4.2 below, only the first six months of the Rolling Forecast shall continue to be binding on the parties, with the remaining 12 months considered to be a good faith non-binding estimate for planning purposes.

MannKind shall be obligated to accept any Rolling Forecast, including any monthly updates thereto, requiring manufacturing output up to the Maximum Capacity of the Existing Equipment. Upon installation and validation of the Expansion Equipment in accordance with the Cap-Ex Letter Agreement, MannKind shall be obligated to accept any Rolling Forecast amount requiring manufacturing output up to 90% of the Maximum Capacity of the Existing Equipment in addition to the Expansion Equipment, provided such capacity utilization is first disclosed in the non-binding portion of the Rolling Forecast.

Without affecting the overall capacity usage of the Existing Equipment or the Expansion Equipment, United Therapeutics may request a change to mix of Product or Semi-Finished Product at any time, including during the binding period of the Rolling Forecast, and MannKind shall comply with such request unless such change would be economically detrimental to MannKind or operationally impracticable.

United Therapeutics may, if justified based on changed demand forecast, request a reduction in Manufacturing at any time, including during the binding period of the

Rolling Forecast, and MannKind shall comply with such request provided that United Therapeutics compensates MannKind by way of a lost profit payment reasonably calculated to compensate MannKind for the shortfall in profit that would have been earned under this Agreement, but without accounting for any profits earned as result of any other agreement between the parties, including any royalties earnable under the License Agreement, had the binding portion of the Rolling Forecast not been reduced.

Purchase Orders and Firm Orders.

For each order of Semi-Finished Product or Product, at least 90 days prior to the specified date of Manufacture, United Therapeutics shall issue to MannKind a purchase order that specifies: (a) purchase order number; (b) the name, Item Number, and quantity of each Product or Semi-Finished Product to be Manufactured; (c) the latest date of Manufacture; and (d) price of the Product or Semi-Finished Product as specified in Appendix B (such purchase order, a “Purchase Order”). For clarity, a Purchase Order shall specify a quantity of Product or Semi-Finished Product but not both Product and Semi-Finished Product.  Each Purchase Order shall reference this Agreement and shall be governed exclusively by the terms of this Agreement.

MannKind shall be obligated to accept any Purchase Order that when aggregated with other Purchase Orders submitted by United Therapeutics, specifies a quantity of Product or Semi-Finished Product that is at or below the quantities specified in the binding portion of the Rolling Forecast for the period covered by such Purchase Orders (each such Purchase Order, a “Firm Order”), and MannKind shall confirm acceptance of each Firm Order within 5 days of receipt of such Firm Order, unless a valid reason that specifically excuses performance under this Agreement exists and is described to United Therapeutics within such 5 day period. If MannKind fails to confirm acceptance of a Firm Order within 5 days of receipt, then such Firm Order shall be deemed to have been accepted by MannKind, and MannKind shall provide confirmation in writing upon request of United Therapeutics. MannKind shall additionally exercise Commercially Reasonable Efforts to Manufacture any quantities of Semi-Finished Product or Product requested by Purchase Order that equal up to 120% of the quantities specified in the Rolling Forecast for such period (“Excess Order Quantity”), and shall acknowledge its ability to do so within the same 5 day acceptance period allotted for Firm Orders.

The parties agree that the terms and conditions of this Agreement shall supersede any term or condition in any purchase order, confirmation or other document furnished by United Therapeutics or MannKind that is in any way inconsistent with the terms and conditions of this Agreement.

Storage, Inventory Reports, Risk of Loss, Title Transfer, Shipment Orders, and Physical Transfer of Product and Semi-Finished Product to United Therapeutics.

Storage of Product, Semi-Finished Product, and Product Materials. At all times following completion of Manufacture and until Product or Semi-Finished Product is physically

transferred to United Therapeutics or United Therapeutics’ shipping vendor, MannKind shall be solely responsible, directly or through an approved Third Party Manufacturing Services provider listed in Appendix D, for storing the Product in complete accordance with the Product Specifications or Semi-Finished Product Specifications, cGMP, the Quality Agreement, and all Applicable Laws, in the Cold Storage Area, or in other storage area mutually approved by the parties in writing. MannKind shall additionally be responsible for storing Product Materials whenever in MannKind’s possession in complete accordance with Product Materials Specifications, cGMP, the Quality Agreement, and all Applicable Laws. Without diminishing its obligations under this Agreement, MannKind shall promptly notify United Therapeutics of any deviations in storage conditions or other circumstances that could potentially give rise to quality concerns. MannKind shall take all necessary and appropriate actions, including and in addition to all specific obligations of MannKind with respect to storage of Product, Semi-Finished Product, and Product Material storage set forth in this Agreement, to protect Product, Semi-Finished Product, and Product Material from loss or damage while in MannKind’s possession.

Transfer of Title. Title to Semi-Finished Product will transfer to United Therapeutics at the time of quality release by United Therapeutics as evidenced by issuance of Release Certificate, and shall remain with United Therapeutics through conversion to Product and physical transfer of Product to United Therapeutics (or alternatively until physical transfer of Semi-Finished Product directly to United Therapeutics). The parties will reasonably cooperate with respect to any documentation required to transfer title to the Semi-Finished Product and Product.

Insurance Responsibilities. The respective insurance responsibilities of the parties with respect to Product, Semi-Finished Product, and Product Materials, are as set forth in Appendix F.

Shipment Orders. For each physical transfer of Product or Semi-Finished Product to United Therapeutics or its shipping vendor, United Therapeutics will provide MannKind with a Shipment Order at least 7 days prior to the proposed date of pickup. MannKind shall confirm availability for the proposed pickup time within 2 business days, and United Therapeutics shall arrange for pickup of the Product or Semi-Finished Product at the designated time and place, and shall be responsible for all transportation costs of Product and Semi-Finished Product upon physical transfer to United Therapeutics.

Certificates of Conformance. With each transfer of Product or Semi-Finished Product, MannKind shall provide the Certificate of Conformance and a copy of the Firm Order (or other ordering document if applicable). If the required documentation is not supplied United Therapeutics may reject the Product and/or Semi-Finished Product.

Inventory Reports. MannKind shall provide United Therapeutics with an Inventory Report each month during the Term, by the close of business on the third business day

of each month, such Inventory Report being current as of close of business on the final business day of the immediately preceding month.  The Inventory Report shall be provided by email to [***], and/or such additional email addresses as instructed by United Therapeutics in writing from time to time.

Serialization.  The parties shall cooperate with each other to implement serialization of Product using bi-dimensional codes to allow the tracking of Product from the Facility to United Therapeutics’ end-users.  MannKind’s costs of such serialization shall be included in COGs.  

Failure to Supply.

Without diminishing any obligation of MannKind to Supply Product and Semi-Finished Product pursuant to the terms of this Agreement, or any right of United Therapeutics to require such Supply, if MannKind anticipates it will be unable to Manufacture or Supply Product or Semi-Finished Product in the quantities specified in a Firm Order, in the Rolling Forecast, or in a Shipment Order, MannKind shall immediately notify United Therapeutics of such anticipated shortfall in writing. Such notice shall describe the reason for the anticipated shortfall and the extent to which MannKind will not meet the requirements of such Rolling Forecast, Firm Order, and/or Shipment Order, and provide United Therapeutics with the expected date of Manufacture or Supply of such Product or Semi-Finished Product.

If it is commercially reasonable for United Therapeutics to accept a new date for delayed Manufacture or Supply of Product or Semi-Finished Product, or if such inability to Manufacture or Supply is not due to a Supply Failure, United Therapeutics shall issue an amended Firm Order or Shipment Order reflecting such new delivery date.

Notwithstanding anything else to the contrary, any Supply Failures, anticipated Supply Failures, or anticipated shortfalls in Supply or Manufacture of Product or Semi-Finished Product, shall be immediately escalated to the MSC.

Without diminishing MannKind’s duty to mitigate any Supply Failure or anticipated Supply Failure, in the event of a Supply Failure or an anticipated Supply Failure that cannot be resolved within 30 days of escalating such Supply Failure or anticipated Supply Failure to the MSC as required hereunder, United Therapeutics may elect to have its own employees or contractors enter the Facility to continue the Manufacturing and Supply operations, or supplement MannKind’s ongoing Manufacturing and Supply operations under the supervision and direction of MannKind’s manufacturing leadership team (“Step-In Right”). Any expenses incurred by United Therapeutics will be used to offset any future payments otherwise due to MannKind under this Agreement. MannKind will provide reasonable assistance and cooperation to United Therapeutics in connection with the foregoing, in order to ensure a stable supply of Product and Semi-Finished Product. Additionally, if MannKind declares a Force Majeure Event, United Therapeutics may exercise its Step-In Right if it is possible for United Therapeutics to do

so in compliance with Applicable Laws.  Upon resolution by MannKind of the root cause of the Supply Failure or anticipated Supply Failure to the reasonable satisfaction of United Therapeutics, United Therapeutics shall cease to exercise its Step-In Right and MannKind shall resume the Manufacturing and Supply of Product and Semi-Finished Product in accordance with this Agreement.

Business Continuity Plan.  MannKind shall, with input and reasonable approval of the MSC, develop, implement and keep current, a written plan detailing strategies for responses to and recovery from a range of events with potential to disrupt Manufacture and/or Supply, as necessary to ensure continuity of Manufacture and Supply, and in accordance with reasonable and customary risk management practices in the pharmaceutical and medical device contract manufacturing industry (such written plan, the “Business Continuity Plan”). United Therapeutics may, at its sole option and expense, implement a separate business continuity program, including without limitation ensuring adequate backup supply for the Product through Third Party vendors or otherwise.
