(Community-driven Sinbad aircraft project)

This Purchase and Work Performance Agreement (the "Agreement") is entered into between the Buyer and GRAD Aeronaut LLC (the "Company"), a limited liability company registered in the State of Delaware, USA, and governs the Buyer's participation in the Sinbad aircraft project (the "Project"), including reservation, purchase, and production of a kit for home assembly of the Sinbad aircraft (the "Kit").

1. Purpose

This Agreement governs the Buyer's participation in the reservation and purchase program for the Sinbad aircraft Kit conducted by the Company.

2. Early-Stage Participation Incentives

To enable installment-style participation and reward early support of the Project, the Company uses a system of conditional units called "Kit Units."

The principle of the system is that the earlier Kit Units are purchased during the development of the Project, the lower their price.

3. Nature of Kit Units

Kit Units are conditional pre-order credits recorded in the Company’s internal accounting system and serve as the exclusive accounting and settlement unit for the production payment and final settlement of the Sinbad aircraft Kit under this Agreement.

Kit Units are not money, securities, or investment instruments and are not redeemable in cash.

Kit Units do not create any obligation of the Company to deliver a Kit until all conditions of this Agreement are fulfilled.

Kit Units exist solely within the Company's internal accounting system.

Kit Units may be transferred between Buyers (Project participants) strictly in accordance with procedures and technical instructions established by the Company. The Company reserves the right to define, modify, suspend, or restrict the transfer mechanism at its discretion.

Kit Units are applicable exclusively toward payment of the Sinbad aircraft Kit and may not be used to pay for any other goods or services of the Company, including but not limited to store purchases, separate services, consulting, accessories, shipping, or any other transactions unrelated to the purchase of the Kit.

4. Kit Price Expressed in Kit Units

100 Kit Units correspond to one Sinbad aircraft Kit.

5. Order Formation

An order is considered formed when the Buyer purchases the first Kit Unit with monetary funds.

6. Personal Kit Units Balance

Each Buyer has a personal Kit Units balance reflecting the total number of Kit Units credited to the Buyer's account, including purchased and validly transferred Kit Units.

The Buyer's balance determines available privilege statuses.

The Buyer may obtain a higher privilege status by purchasing additional Kit Units.

Until the Buyer voluntarily designates Kit Units for redemption, such Kit Units remain fully under the Buyer's control.

The Company is not entitled to independently deduct, redeem, use, or treat Kit Units as redeemed without the Buyer's confirmed action through the designated interface, except in cases expressly provided for in this Agreement (including consequences set forth in Sections 11–13).

7. Automatic Status Upgrade

When the Buyer's balance reaches the level required for the next privilege status, the status is automatically upgraded and becomes active.

8. Time Limit for Status Upgrades

The Buyer may upgrade privilege status only until the Company sends notice of readiness to begin production of the order.

From the moment such notice is sent, the achieved privilege status becomes locked and cannot be changed.

9. Changes in Kit Units Pricing and Information on the Shape Sinbad Page

The price of Kit Units may change as the Project moves to new development or production stages.

The current Kit Units price in effect at the time of purchase, as well as the applicable pricing conditions (including price-lock conditions for eligible statuses, where applicable), are published on the Shape Sinbad page and constitute accurate information for the purpose of purchasing Kit Units at that moment.

Any forward-looking information on the Shape Sinbad page regarding future stages, projected timelines, anticipated price changes, production plans, or other future parameters of the Project may be indicative only and does not in itself constitute a binding obligation of the Company.

10. Price Lock for Standard Status

For Buyers who reach the Standard privilege status, the price of all subsequent Kit Units for the relevant Kit is fixed at the level in effect at the time that status was achieved.

11. Production Payment (50 Kit Units)

After the Company sends notice of readiness to begin production of the order, the Buyer has thirty (30) calendar days to ensure that at least 50 Kit Units are available on the Buyer's balance and voluntarily designate them for redemption in accordance with Section 14 of this Agreement.

The production payment is carried out exclusively through redemption of 50 Kit Units from the Buyer's balance at the moment production begins, provided the Buyer has performed the designation action described in Section 14.

If the required Kit Units are not available and/or not designated for redemption within the specified period, the procedure described in Section 12 applies.

12. Failure to Secure the Production Payment: Freeze, Company Decision, Refund

If, within the period specified in Section 11, the Buyer's balance does not contain at least 50 Kit Units and/or the Buyer has not designated the required Kit Units for redemption, the order is placed in frozen status.

The Company may keep the order frozen for up to ninety (90) calendar days after the expiration of that period.

After the freeze period, the Company decides either to cancel the order or restore it under terms determined by the Company.

If the order is canceled by the Company, the Buyer is entitled to a refund strictly limited to the total amount of monetary funds actually received by the Company from that Buyer in exchange for purchased Kit Units, minus non-refundable payment provider and banking fees, unless otherwise provided in the Refund Policy.

Refunds do not include and do not apply to:

Kit Units received from other Buyers through transfer;

Kit Units granted by the Company as bonuses, incentives, or promotional allocations;

Kit Units obtained by any non-monetary means;

Any payments made for other goods, services, shipping, store purchases, or unrelated transactions.

Refunds are made from incoming funds of new orders within a reasonable time determined by the Company and to the original payment method, where technically possible.

13. Final Settlement (Remaining 50 Kit Units)

The remaining 50 Kit Units must be available on the Buyer's balance and designated for redemption within thirty (30) calendar days after the Company sends notice that the order is ready for pickup or delivery.

The final settlement is carried out exclusively through redemption in accordance with Section 14.

14. Kit Units Redemption Mechanism

Redemption is the formal act by which Kit Units are permanently deducted from the Buyer's balance and applied toward the corresponding stage of payment under this Agreement.

The production payment and final settlement are carried out solely through redemption of the required number of Kit Units.

Redemption is performed only if the Buyer's balance contains the full number of Kit Units required for the relevant stage.

To initiate redemption, the Buyer must independently designate the required number of Kit Units for redemption through the interface on the Buyer's personal page on the Company's website.

Until such confirmed action is taken by the Buyer, the Company is not entitled to:

independently deduct Kit Units from the Buyer's balance;

treat Kit Units as redeemed;

apply Kit Units toward payment;

consider the relevant payment stage fulfilled.

Partial redemption is not permitted.

If the Buyer does not designate the required number of Kit Units for redemption, redemption does not occur and the procedures set forth in this Agreement for the relevant stage shall apply.

Redeemed Kit Units are not subject to restoration, reversal, or reuse.

15. Production Queue and Priority

Orders are fulfilled in queue order. The Buyer's initial position in the queue is determined by privilege status and confirmed fulfillment of the relevant stage requirements.

The Company may adjust the queue for objective production, logistical, or regulatory reasons.

16. Indicative Nature of Timelines

All production, assembly, and delivery timelines are indicative only.

The Company is not liable for indirect damages.

17. Kit Contents and Exclusions

Unless otherwise stated, the Kit does not include: engine and related systems, propeller, wheels and brakes, fuel systems, ballistic parachute systems, avionics, navigation or landing lights, paint/finish, or shipping.

Shipping is arranged and paid by the Buyer separately.

18. Airworthiness and Responsibility

The Company does not guarantee the airworthiness, legality, or operational condition of the completed aircraft.

The Buyer bears full responsibility for final assembly, inspection, registration, maintenance, flight testing, and operational safety.

19. Communication and Buyer Information Page

By participating, the Buyer agrees to receive updates and notices via email.

Order status and official notices are published on the Buyer's personal page and/or sent by email.

A notice is deemed delivered at the moment it is sent by the Company.

20. Authorized Payment Entities

The Company may use authorized legal entities or individual entrepreneurs to receive payments on its behalf.

Information about the current authorized payment entity is published on the Company's official website and forms an integral part of this Agreement.

21. Fraudulent or Unauthorized Payments

The Company reserves the right, at its sole discretion, to refuse recognition, suspend, or cancel any payment that it reasonably believes was made as a result of fraud, unauthorized access, material misrepresentation, or other unlawful activity.

22. Order Pickup, Storage, and Extension of Unclaimed Period

The Buyer must collect the paid order within forty-five (45) calendar days after the Company sends notice that the order is ready for pickup or delivery.

If the order is not collected within this period, the Company may begin charging storage and insurance fees.

If the order is not collected within ninety (90) days, the Company may cancel the order and apply the refund procedure set forth in this Agreement and the Refund Policy, minus applicable overhead, incurred expenses, and non-refundable payment provider fees.

23. Aircraft Identification Plate

The Buyer may change only the serial number and personal signature on the Aircraft Identification Plate until the Company sends notice that production is ready to begin.

After that, the information becomes final and cannot be changed.

24. Force Majeure

The Company is released from liability for partial or complete failure to perform its obligations under this Agreement if such failure results from force majeure circumstances beyond the Company's reasonable control, including but not limited to war, armed conflicts, terrorist acts, mass unrest, actions of governmental authorities, sanctions, epidemics or pandemics, natural disasters, failures of power supply, communications, internet, banking or payment systems.

Performance deadlines are extended for the duration of such circumstances and their consequences.

25. Governing Law and Priority

This Agreement is governed by the laws of the State of Delaware, USA.

In the event of any conflict, this Agreement prevails, followed by the Refund Policy, the Terms of Use, and the Privacy Policy.

(Community-Driven Sinbad Aircraft Project)

This Refund Policy (the "Policy") applies to the Community-Driven Sinbad Aircraft Project (the "Project") and governs the terms for refunding monetary payments made by the Buyer for the purchase of Kit Units.

This Policy applies to the extent it does not conflict with the Purchase and Work Performance Agreement (the "Agreement"). In the event of any conflict, the Agreement prevails.

This Policy applies exclusively to monetary funds paid for the purchase of Kit Units intended to be used toward the acquisition of the Sinbad aircraft Kit. It does not apply to payments for other goods or services of the Company, including store purchases, separate services, shipping, consulting, or any unrelated transactions.

Kit Units are conditional pre-order credits recorded in the Company’s internal accounting system and serve as the exclusive accounting and settlement unit for the production payment and final settlement of the Sinbad aircraft Kit under the Agreement. They are not money, do not constitute stored funds, and have no independent cash value.

1. Refund of Individual Payment Within 14 Days

The Buyer may request a refund of a specific payment within fourteen (14) calendar days from the date of that payment, provided that the Project has not entered the production stage and no irreversible processes directly related to that payment have been initiated.

After the expiration of the fourteen (14) calendar day period, refunds at the Buyer's initiative are no longer available. Any further refund may occur only if the order is cancelled by the Company in accordance with the Agreement.

The refundable amount is strictly limited to the monetary funds actually received by the Company in exchange for the corresponding Kit Units, minus non-refundable payment provider and banking fees.

Refunds do not include and do not apply to:

• Kit Units received from other participants through transfer;
• Kit Units granted by the Company as bonuses, incentives, or promotional allocations;
• Kit Units obtained by any non-monetary means;
• Any payments made for goods or services unrelated to the purchase of Kit Units.

2. Refund Barrier After 14 Days

After fourteen (14) calendar days from the date of payment, funds are not refundable until the order is cancelled by the Company in accordance with the Agreement.

Order formation is defined in the Agreement as the moment the Buyer acquires the first Kit Unit with monetary payment.

3. Refund After Cancellation by the Company

If the Company cancels the order in accordance with the Agreement, the Buyer is entitled to a refund strictly limited to the monetary funds actually received by the Company from that Buyer for purchased Kit Units, minus non-refundable payment provider and banking fees, unless otherwise provided in Section 4 of this Policy.

The refund amount is calculated as follows:

1. Only those Kit Units are considered which:
   • were purchased by the Buyer with monetary funds;
   • remain on the Buyer's balance at the time of refund calculation;
   • were not transferred to other participants;
   • were not redeemed.
2. Kit Units received from other participants through transfer are not included in the refund calculation and have no monetary value for refund purposes.
3. If the Buyer previously transferred part of the Kit Units originally purchased, the refund amount is determined based on the price of the earliest purchased Kit Units remaining on the Buyer's balance at the time of cancellation (chronological accounting from first purchases to later purchases).

Accordingly:

• transferred Kit Units are excluded from the calculation;
• in case of partial refund, the calculation applies to the earliest (typically lower-priced) purchases;
• Kit Units received from other participants do not increase the refundable amount.

Refunds are issued from incoming funds of new orders within a reasonable time determined by the Company and to the original payment method where technically possible.

4. Cancellation After Production Start or Failure to Redeem Remaining Units

If, after production has begun and/or after the production payment has been redeemed, the Buyer fails to ensure the availability and voluntary designation for redemption of the required remaining Kit Units within the specified time, the Company may cancel the order.

In such case, in addition to non-refundable payment provider and banking fees, the Company may retain agreed compensation in the amount of 10,000 (ten thousand) USD as compensation for the Company's costs, reservation of production capacity, administrative expenses, and lost opportunity, but not exceeding the total monetary funds actually received by the Company from that Buyer.

Any remaining amount, if any, shall be refunded from incoming funds of new orders within a reasonable time determined by the Company.

Redeemed Kit Units are not refundable, reversible, or restorable.

5. Method and Timing of Refunds

Refunds are issued from incoming funds of new orders within a reasonable time determined by the Company and to the original payment method used by the Buyer.

Any exchange-rate differences, intermediary bank fees, or payment-provider charges are the responsibility of the Buyer.

6. Verification and Fraud Prevention

The Company may request identity, payment, and transaction verification before processing a refund in order to prevent fraud, unauthorized access, or misuse.

7. Force Majeure

The Company is released from liability for partial or complete failure to perform its obligations under this Policy if such failure results from force majeure circumstances, including, but not limited to: war, armed conflicts, terrorist acts, mass unrest, revolutionary events, actions of government authorities or regulators, sanctions or restrictions, epidemics and pandemics, natural disasters (floods, hurricanes, tornadoes, tsunamis, earthquakes, lightning strikes, fires, excessive precipitation, icing), failures and outages in power supply, communications, internet, banking and payment systems, as well as other events beyond the reasonable control of the Company that prevent it from fulfilling its obligations.

Performance deadlines are extended for the duration of such circumstances and their consequences.
