Certain Drone parts may be, from time to time and upon specific request by Lift Aircraft, ordered, supplied and invoiced to a third party indicated by Lift Aircraft, which must accept Materialise T&Cs and shall be responsible, jointly with Lift Aircraft, of any payment relating thereto.

2.2. Quality. Materialise will ensure that the Drone Parts shall be in full compliance with the digital design files provided by Lift Aircraft (taking into account the agreed tolerances) and will possess at least the same quality of any sample or model provided by Materialise and approved by Lift Aircraft and more specifically shall meet the agreed Quality Standards.

2.3. Production Capacity. Materialise shall ensure sufficient production capacity to meet all orders placed and use reasonable efforts to meet any orders in excess of the forecasted volumes. Materialise shall immediately notify Lift Aircraft in writing if it anticipates that its production capacity may be insufficient to meet future supply demand by Lift Aircraft, in which case the Parties shall discuss appropriate solutions.

3. ORDERING PROCEDURES AND SHIPMENT

3.1. Orders. Lift Aircraft, or, as the case may be, the third party indicated by Lift Aircraft in writing, orders Drone parts electronically per e-mail. The mentioned discounts in Exhibit A can only be applied if Lift Aircraft orders a full set of Drone Parts (92 parts) and forecasted volumes are reached. A PO will be signed with binding volumes and prices for fixed period of one (1) year, based on which Lift Aircraft can retrieve full set orders. Based on the PO, if the volumes are not ordered, by the end of the one (1) year period Materialise will deliver an invoice the full volumes. If a full set is not ordered, the individual prices can be applied, as indicated in Exhibit A. Materialise will electronically confirm acceptance of the order and the applicable lead time within the next working day upon receipt of that order. If no confirmation was sent, Lift Aircraft holds the responsibility to contact Materialise as to check the delivery of the made order. No adaptations can be made to orders after the order was placed. Orders exceeding the forecast will not be binding upon Materialise until confirmed electronically. For orders exceeding the forecast, Materialise will be entitled to adjust lead times.

3.2. Delivery. Materialise shall strive to keep the delivery time for fulfilling any order as short as possible and ensure that the delivery time will be in accordance with what has been agreed. Public holidays in Germany will not count as working days. Materialise will ship produced Drone parts EX-Works to Lift Aircraft, making use of its existing agreements with courier and postal services.

For each delivery by Materialise, on top of the agreed prices Materialise will invoice to Lift Aircraft an additional amount stated in Exhibit A point 5. Deliveries due to delays of Materialise will be taken on his behalf.

Materialise remains the sole owner of the parts until the entire payment is done by Lift Aircraft, taxes included.

Each delivery contains a delivery sheet indicated what was delivered per order.

3.3. Quallty Control. Materialise undertakes to continuously monitor the quality of its products processes and make such improvements as may be reasonable expected from a professional high-end 3D printing services provider. More specifically, Materialise undertakes to continuously apply the quality control measures specified in Exhibit B.

3.4. Inspection. Within a maximum period of five (5) days upon delivery to Lift Aircraft, Lift Aircraft will inspect delivered Drone Parts for visible production defects. Any rejected Drone part will be reported to Materialise within five (5) working days upon determination of the defect. In case of a justified claim by Lift Aircraft, Materialise shall replace such Drone part (with transport cost to Lift Aircraft covered by Materialise) within the maximum delivery time for such type of Drone Part referred to in Section 3.2. If requested by Materialise, Lift Aircraft shall substantiate its claim by returning the rejected Drone Part to Materialise so that Materialise can examine the defective Drone Part for ongoing quality assurance purposes.

3.5. Remakes. We identify three types of remakes:

1. Remakes during the production process of Materialise. (i.e. Lead times)

2. Remakes upon receipt by Lift Aircraft. Drone parts can be rejected by Lift Aircraft if not in line with signed quality requirements (i.e. Visible building layers, wrong parts, dimension out of tolerance)

3. Remakes during final assembly process at Lift Aircraft (i.e. breakage when mounting)

The remakes indicated in point 1: These remakes are free of charge.

The remakes indicated in point 2: Upon receipt of the Drone Parts, Lift Aircraft has five (5) working days to notify Materialise about the non-conformity Drone Parts. If Materialise requires, the Drone Parts must be sent back in the original package. The remakes will be processed simultaneously with the ongoing orders. These remakes are free of charge.

The remakes indicated in point 3: We ask Lift Aircraft to notify Materialise about these part defects. These remakes will be invoiced.

Exhibit B: Quality Standards

1. Quality Procedures - PRODUCTION OF DRONE PARTS

Materialise is a supplier of 3D printing services of Drone parts designed by Lift Aircraft. For the sake of clarity, Materialise prints these parts according ISO 9001, not under EN9100 certification. A material and part Certificate of Conformity (CofC) will be issued for each delivery.

2. Quality control

This section gives an overview of all quality control steps performed during manufacturing of drone parts. As per control plan 20201015_control Plan_LIFTAIRCRAFT_v1 (Attached hereto as Attachment 2)

3. Building quality check

1 Density cube and 1 tensile bar (as per PGE-PROD-131) will be built along the parts for each build job started. The density cube will be put in stock and will only be tested in case of any non-conformity impact (if applicable). The tensile bar will be immediately tested and evaluated. Any process change which has influence on the part quality will be communicated upfront to Lift Aircraft.

The table indicates the minimum acceptable values for the tensile bars that undergo the HIP treatment process:

Rp0,2 [Mpa]		Rm [Mpa]		AS[%]		z [%]		E [Gpa]
	765		859		12,4		37,5		107,2

The evaluation of the tensile bars is in accordance with DIN EN2002-1.

4. Part quality check

After support removal and surface finish (standard procedures) each part type is being measured with a measurement tool according to the instructions on the technical 20 drawings. Areas to be measured are defined case by case between Materialise and Lift Aircraft (see technical drawings listed in Exhibit A, point 2 Technical Drawing Reference and Revision). A measurement report will be shipped upon request.

Visual checks regarding defects will be performed as per PGE-PROD-131.

In case of a non-conformity, the project manager at Lift Aircraft can be contacted to decide whether parts still can be sent to the customer. In this case a concession report will be shipped with the part.

5. Labeling

Labeling will be performed via Bag & Tag method for shipment. Label content: Part name, project number+position, Build ID, technology. Parts will be physically labelled during printing, with Build ID+ Part counter. Attached hereto as Attachment 3: Lift Aircraft_Ti_label positioning_v1.

6. Packaging

As per PGE-PROD-013. Materialise will ship each produced part type wrapped in protective foil - EX- Works to Lift Aircraft, via UPS in a cardboard box, filled with chips. Delays of the shipments will not be taken on behalf of Materialise except if these delays are cal!sed by Materialise manufacturing process.

Materialise will include the HTS codes on the invoice as indicated and instructed by Lift Aircraft, assuming no responsibility regarding the correctness of the HTS codes. Nevertheless, if orders are placed with Hannes Brenning, Gert Brabants or Dorina Kovacs, should Materialise indicate a HTS code different from the one indicated by Lift Aircraft, Materialise will be responsible for any additional custom duty incurred by Lift Aircraft as a direct consequence of the different HTS code indicated by Materialise.

The risk of loss is transferred to Lift Aircraft upon delivery of the parts EXW.

Materialise remains the sole owner of the parts until the entire payment is done by Lift Aircraft, taxes included.

7. FAI

Accepted and signed FAI by both parties is mandatory to start series production.

FAI samples represent the final approved product by Materialise and Lift Aircraft. FAI samples are created when a new product is introduced in the Certified Manufacturing production line of Materialise. Certified Manufacturing can only pursue based on an agreement on the quality of the FAI samples.

An order placed withol!t an agreement on FAI samples will be considered Non-Certified Manufacturing process and a written permission from Lift Aircraft is required to process the order. There will be no quality guarantees provided by Materialise on Non-Certified Manufacturing.

The procedure of creating new FAI parts starts with adding the product well-defined to the product portfolio, testing the product in a Certified Manufacturing line and aligning on pricing, lead times and quality between Lift Aircraft and Materialise. This procedure will take minimum 2 weeks till multiple months depending on the scope of the new product.

Quality requirements articulated by Lift Aircraft and the feedback from Materialise manufacturing and quality team will be evaluated based on the FAI samples during a mutual FAI check.

Prior to FAI sample production, all final quallty requirements will be agreed and documented in FGE-DEV-002 Technical requirement specification sheet (attached hereto as Attachment 2). This document needs to be signed by both parties before any FAI production can start.

The FAI samples which are approved during the FAI check and which are in line with the quality requirements are documented in the FAI.

8. Heat Treatment Process

A stress relief heat treatment will be applied to all printed Titanium parts before platform removal.

9. HIP Process Specifications:

Temperature: 920°C ± 10°c

Process Time: 120mins -0/+30mins
