5. FEES.

5.1 Fees and Payment. Horizon Quantum will pay IonQ the Fees for Services as set forth in an executed SOW, as applicable (the “Fees”). Fees are non-refundable even if Horizon Quantum chooses, for any reason, not to receive the full amount of the Services. Compute Services not fully utilized will be forfeited at the end of the period in which they were to be used; unless otherwise specified in a Statement of Work, this period is monthly. In no event will any unused Services associated with the Fees be refunded or roll-over or be applied in a future period. Non-payment or any more than three (3) instances of late payment or late payment of more than thirty (30) days of undisputed Fees are material breaches of this Agreement. If any amount is past due more than thirty days, Horizon Quantum will pay interest on the overdue balance at the rate of one percent per month or the maximum permitted by law, whichever is less, plus all actual and reasonable expenses of collection, including attorneys’ fees. IonQ will be entitled to withhold performance and discontinue Service until all amounts due are paid in full.

5.2 Taxes. The parties are responsible for their own net income taxes. Other than net income taxes imposed on IonQ, Horizon Quantum will bear all taxes, duties, and other governmental charges (collectively, “Taxes”) resulting from this Agreement, including all import duties, value-added taxes (VAT), goods and services taxes, and other governmental charges imposed by the country of delivery (the “Destination Country”) or any other jurisdiction outside of the United States. The parties agree that all goods provided by IonQ to Horizon Quantum under this Agreement shall be delivered DAP, Delivery Point, per Incoterms® 2020 rules, where the “Delivery Point” is the Computing Data Center in the Destination Country. Horizon Quantum will pay any additional Taxes as are necessary to ensure that the net amounts received by IonQ after all such Taxes are paid are equal to the amounts that IonQ would have been entitled to in accordance with this Agreement as if the Taxes were not imposed. Horizon Quantum will make all payments of Fees to IonQ in USD and free and clear of, and without reduction for, any withholding taxes, provided that Horizon Quantum may withhold any mandatory taxes required by the laws of the Destination Country if Horizon Quantum is obligated to do so, and shall immediately remit such amounts to the relevant tax authorities. If withholding is required, Horizon Quantum will withhold and remit the required amount to the taxing authority, increase the payment (gross-up) so that IonQ receives the full amount it would have received absent withholding, and deliver evidence of withholding tax payment to IonQ. Horizon Quantum shall be responsible for acting as the Importer of Record for all components, materials, and the final Quantum Computing System. The parties shall cooperate (at Horizon Quantum’s sole cost and expense) to ensure correct compliance with applicable customs and tax obligations. This cooperation includes IonQ providing necessary documentation (e.g., commodity codes, proofs of origin) and Horizon Quantum (i) appointing a customs broker acceptable to IonQ (such acceptance not to be unreasonably withheld), (ii) ensuring the timely customs clearance of the goods, and (iii) arranging and executing final delivery to the designated installation site within the Computing Data Center at a time coordinated with IonQ. IonQ shall not be responsible for any delays, penalties, or increased costs caused by Horizon Quantum’s failure to timely execute its duties as Importer of Record or its failure to timely remit any required withholding taxes. Horizon Quantum will indemnify, defend, and hold harmless IonQ in connection with any claims, liabilities, penalties, interest, and proceedings brought by any taxing authorities in connection with this Agreement. Horizon Quantum will indemnify and defend IonQ in connection with any proceedings brought by any taxing authorities in connection with Horizon Quantum’s tax obligations under this Agreement and IonQ will indemnify and defend Horizon Quantum in connection with any proceedings brought by any taxing authorities related to IonQ’s payroll-related tax obligations.

5.3 Customs Compliance and Trade Secret Protection. IonQ will provide Horizon Quantum with the applicable Commodity Codes and high-level technical descriptions for all sub-assemblies of the Quantum Computing System to facilitate timely customs entry. IonQ shall provide such Commodity Codes to Horizon Quantum no later than thirty (30) days prior to the scheduled shipment date to ensure sufficient time for applicable import security filings and the coordination of customs brokerage services. IonQ will not be required to disclose its Bill of Materials (BOM) or proprietary technical drawings to Horizon Quantum. To satisfy Horizon Quantum’s “reasonable care” obligations as the Importer of Record, IonQ will, upon request, provide a copy of a Binding Ruling confirming the provided Commodity Codes. In the event a taxing authority requires a detailed BOM for audit purposes, IonQ may elect to (i) provide such documentation directly to the authority, (ii) request confidential treatment of the BOM to ensure it is not subject to public disclosure or shared with Horizon Quantum, and (iii) provide Horizon Quantum with written confirmation that the required data has been submitted.

EXHIBIT A

GENERAL SERVICE DESCRIPTIONS

Cloud Compute Services are provided through IonQ’s Quantum Cloud, which allows clients to run, retrieve, and manage quantum workloads via major open-source quantum computing SDKs (e.g., Qiskit, Cirq, CQ tket, Q#, QCW Forge, ProjectQ, PennyLane, TensorFlow, etc.), via a RESTful API, or via a web console. Clients can also optionally take advantage of IonQ’s proprietary compilation and optimization toolchain, a direct “hardware-native” circuit specification, and IonQ’s proprietary error mitigation solutions. Access to computation (running quantum circuits) on IonQ’s quantum systems may be granted to one specific system, a class of systems, a subset of IonQ’s system, or all of them.

On-site Compute Services provide quantum compute access to entire quantum systems for exclusive use. On-site quantum systems can be hosted by IonQ in one of its quantum data centers or installed on-premises at a client’s qualified data center. In all cases, a client’s dedicated quantum system is supported and maintained solely by IonQ.

Access to IonQ’s Consulting Services team of engineers who specialize in quantum implementations including algorithms and direct knowledge of IonQ’s quantum systems. All algorithm and application development service engagements include a predetermined scope and/or a number of professional service hours to be provided to the client. These engagements are used to deliver quantum implementation (software) that is customized to the Client’s needs using IonQ’s latest software platform, tools, and algorithms. Some algorithm and development service engagements can include access to quantum systems (specific systems or general access, specified as number of compute hours or qubit gate count). Algorithm and development service engagements are priced through an hourly rate (which could include multiple rates for different skills and levels of experience). All algorithm and development engagements depend on availability and individual consultants (engineers) are assigned by IonQ based on availability and the required technical tasks to be accomplished. Although algorithm and application development can be performed in collaboration with the client, and client engineers might find them a helpful educational experience, they are not intended as training activities. For deliberate quantum training and education, specific “quantum training and education” services should be secured.
