(Community-Driven Sinbad Aircraft Project)

This Purchase and Performance Agreement (“Agreement”) is entered into between the Buyer and GRAD Aeronaut LLC (“Company”), a limited liability company registered in the State of Delaware, USA, and governs participation in the Community-Driven Sinbad Aircraft Project (the “Project”), including the reservation, purchase, and production of a parts kit for the home-built Sinbad aircraft.

1. Purpose

This Agreement governs the Buyer’s participation in the Project and the procedure for reserving and purchasing a parts kit for the home-built Sinbad aircraft conducted by the Company.

2. Early-Stage Participation and Incentives

To enable installment payments and to reward Buyers for participating in the Project at an early stage, the Company uses a system of conditional units (“Kit Units”). The following principle applies: the earlier in the Project’s development stage the Kit Units are acquired, the lower their price.

3. What Kit Units Are

Kit Units are pre-order credits used exclusively toward the purchase of a Sinbad aircraft kit.

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

Kit Units do not create an obligation for the Company to deliver a kit until all conditions of this Agreement have been fulfilled.

4. Order Formation

An order is deemed formed at the moment the Buyer acquires the first Kit Unit with monetary payment.

5. Kit Value in Kit Units

1,000 Kit Units correspond to one complete Sinbad aircraft kit.

6. Personal Kit Units Balance

Each Buyer has a personal Kit Units balance reflecting the total number of Kit Units acquired.

The Buyer’s balance determines the set of available privilege statuses.

The Buyer attains higher privilege status by acquiring additional Kit Units.

7. Automatic Status Upgrade

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

8. Status Upgrade Cutoff

The Buyer may upgrade privilege status only until the Company sends a notice that the order is ready for production.

From the moment such notice is sent, the attained privilege status is locked and may no longer be changed.

9. Changes in Kit Unit Pricing

The purchase price of Kit Units changes as the Project advances to subsequent development and production stages.

The list of Project development stages, the current Project status, projected price changes, privilege statuses and their scope are published in the materials displayed on the Shape Sinbad page containing the PayPal payment button, in the version effective at the time the Kit Units are acquired. These materials are provided for reference only and are not binding.

10. Price Lock for Standard Status

For Buyers who have reached the Standard privilege status, the price for all subsequent Kit Units purchased from the Company for the same aircraft kit is fixed at the level in effect at the time such status is achieved.

11. Production Payment (500 Kit Units)

After the Company sends the notice that the order is ready for production, the Buyer has thirty (30) calendar days to increase the Kit Units balance to 500 Kit Units (50% of the total kit price in Kit Units).

12. Non-Payment and Order Freeze

If the balance is not increased to the required level within the period specified in Section 11, the order is placed in a frozen status.

The Company may maintain the order in frozen status for up to ninety (90) calendar days after the expiration of the payment period.

13. Cancellation by the Company and Refunds

After the freeze period described in Section 12, the Company will decide whether to cancel the order or reinstate it under terms determined by the Company.

If the Company cancels the order, the Buyer is entitled to a full refund of all monetary funds actually received by the Company from the Buyer, minus non-refundable payment, banking, and payment-provider fees, unless otherwise provided in the Refund Policy.

Refunds are issued as funds become available from new orders and within a reasonable time determined by the Company, to the original payment method.

14. Final Settlement (Remaining 500 Kit Units)

The remaining fifty percent (50%), equal to 500 Kit Units, must be acquired within thirty (30) calendar days after the Company sends the notice that the order is ready.

15. Non-Payment of the Remainder and Agreed Compensation

If the Buyer fails to acquire the remaining 500 Kit Units within thirty (30) calendar days after the Company sends the notice of readiness, the Company may cancel the order.

In such case, the refund procedure set forth in the Refund Policy applies, including the Company’s right to retain agreed compensation in the amount and under the conditions set forth in the Refund Policy effective at the time the order was formed, as well as non-refundable payment, banking, and payment-provider fees.

16. Production Queue and Priority

Orders are fulfilled in a production queue. The Buyer’s initial position in the queue is determined by the attained privilege status and confirmed payment volume.

The Company will use reasonable and good-faith efforts to honor the queue defined by the Buyer’s privilege status and may deviate only due to production availability, supply delays, design changes, regulatory requirements, logistics constraints, force-majeure events, or other factors beyond the Company’s reasonable control.

17. Start of Production

Production begins after the Company receives a confirmed production payment and has available production capacity.

18. Indicative Timelines and Limitation of Liability

Any production or delivery timelines are indicative only and do not constitute binding obligations.

The Company shall not be liable for indirect, consequential, or incidental damages, including lost profits, downtime, or additional expenses incurred by the Buyer due to changes in production or delivery timelines.

19. Kit Contents and Exclusions

Unless otherwise stated, the kit does not include:

engine and related systems, propeller, wheels and braking systems, fuel systems, ballistic parachute systems, avionics, navigation and landing lights, finishing/painting and delivery from the Company’s warehouse.

Shipping and transportation are arranged and paid for separately by the Buyer.

20. Airworthiness and Responsibility

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

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

21. Communications and Notices

Official notices and order status updates are published on the Buyer’s personal information page at gradaeronaut.com and/or sent to the Buyer’s registered email address.

A notice is deemed properly given at the moment it is sent by the Company, regardless of actual receipt.

22. Force Majeure

The Parties are освобождаются от ответственности for partial or total non-performance of obligations if such non-performance results from force-majeure events, including but not limited to: war, armed conflicts, terrorist acts, civil unrest, revolutionary events, actions of governmental or regulatory authorities, sanctions or restrictions, epidemics and pandemics, natural disasters (floods, hurricanes, tornadoes, earthquakes, lightning strikes, fires, excessive atmospheric precipitation, icing), failures or disruptions of power supply, communications, internet, banking or payment systems, and other events beyond the Company’s reasonable control.

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

23. Authorized Payment Entities

The Company may use authorized payment organizations or individual contractors to receive payments on its behalf.

The current authorized payment entity is listed on the Company’s website in the section, which forms an integral part of this Agreement.

24. Fraudulent or Unauthorized Payments

The Company reserves the right to refuse, suspend, or cancel recognition of any payment reasonably believed to result from fraud, unauthorized access, material misrepresentation, or unlawful activity.

25. Aircraft Identification Plate

The Buyer may modify only the serial number and personal signature on the Aircraft Identification Plate until the Company sends the notice of production readiness.

Thereafter, such information becomes final and immutable for production.

26. 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.

This Refund Policy applies to the Community-Driven Sinbad Aircraft Project and governs the refund of payments made by the Buyer in connection with participation in the Project. It applies to the extent it does not conflict with the Purchase and Performance Agreement.

1. Refund of Individual Payments 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 production and no irreversible processes directly related to that payment have been initiated.

Requests must be submitted via the Buyer’s personal information page on the Company’s website and/or to the Company’s email address listed on the site.

2. Agreement Priority and Refund Barrier

After fourteen (14) calendar days from the date of a 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 under the Agreement, the Buyer is entitled to a full refund of all monetary funds actually received by the Company from the Buyer, minus non-refundable payment, banking, and payment-provider fees, unless otherwise provided in Section 4 of this Policy.

4. Cancellation After Production Start / Non-Payment of the Remainder

If, after production has begun and/or after the production payment has been made, the Buyer fails to acquire the remaining 500 Kit Units within the specified time, the Company may cancel the order.

In such case, in addition to non-refundable payment, banking, and payment-provider 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 the Buyer.

Any remaining amount, if any, shall be refunded as funds become available from new orders and within a reasonable time determined by the Company, to the original payment method.

5. Method and Timing of Refunds

Refunds are issued as funds become available from new orders and within a reasonable time determined by the Company, to the original payment method used by the Buyer.

Any exchange-rate differences or intermediary fees are borne by the Buyer.

6. Verification and Fraud Prevention

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

7. Force Majeure

The Parties are released from liability for partial or total non-performance of obligations under this Policy if such non-performance results from force-majeure events, including but not limited to: war, armed conflicts, terrorist acts, civil unrest, revolutionary events, actions of governmental or regulatory authorities, sanctions or restrictions, epidemics and pandemics, natural disasters (floods, hurricanes, tornadoes, earthquakes, lightning strikes, fires, excessive atmospheric precipitation, icing), failures or disruptions of power supply, communications, internet, banking or payment systems, and other events beyond the Company’s reasonable control.

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