Effective Date: July 1, 2026  |  Atto Research Co., Ltd.

These Enterprise Service Terms of Use (the "Terms") constitute an agreement between Atto Research Co., Ltd. ("Atto Research") and the enterprise customer that accepts these Terms ("Customer"). These Terms govern Customer's use of Atto Research's AIRouter service (the "Service"). These Terms become effective on the earlier of the date Customer first electronically accepts these Terms or the date Customer first accesses the Service (the "Effective Date").

These Terms are not intended for individual users. Personal services are governed by separate Consumer Terms of Use. Only a person authorized to bind Customer may accept these Terms.

A. Service

A.1. Overview. Subject to these Terms, Atto Research grants Customer the right to use the Service, including the right to use the Service in connection with products or services that Customer provides to its own customers or end users ("Users").

A.2. Third-Party Features. Customer may, in its discretion, use features, services, or content provided by third parties through the Service ("Third-Party Features"). Third-Party Features are not part of the Service, and Atto Research is not responsible for Third-Party Features.

A.3. Feedback. If Customer voluntarily provides feedback regarding the Service, Atto Research may use such feedback without restriction.

A.4. Delivery / Service Availability Schedule. After payment is completed, the Service will become available within one (1) business day following account approval and completion of service configuration. If a separate agreement or technical integration is required, the service availability schedule will be determined by separate mutual agreement.

B. Customer Content

As between the parties and to the extent permitted by applicable law, Atto Research acknowledges that Customer (a) retains all rights in and to Inputs and (b) owns Outputs. Atto Research waives any rights it may have in Customer Content under these Terms and assigns to Customer any rights it may have, if any, in Outputs, provided that Customer complies with these Terms. Atto Research will not train models on Customer Content collected through the Service.

"Inputs" means materials submitted to the Service by Customer or Users, and "Outputs" means results generated by the Service in response to Inputs. Inputs and Outputs are collectively referred to as "Customer Content."

C. Data Privacy

Data submitted through the Service will be processed in accordance with the separate Data Processing Addendum ("DPA"), which is incorporated into these Terms by reference.

D. Trust, Safety, and Use Restrictions

D.1. Compliance with Laws. Each party will comply with all laws and regulations applicable to its provision of the Service (Atto Research) and use of the Service (Customer), particularly laws and regulations relating to data protection and privacy.

D.2. Policies and Service Terms. Customer and Users must comply with these Terms, including (a) the Usage Policy, (b) the Supported Countries and Regions Policy, and (c) the Service Specific Terms. These policies are incorporated into these Terms by reference. Customer will cooperate with reasonable requests for information made by Atto Research to verify compliance with the Usage Policy.

D.3. Limitations of Outputs. Customer is responsible for evaluating whether Outputs are suitable for Customer's intended use, including whether human review is required. Customer will notify Users that factual statements in Outputs may be inaccurate, incomplete, misleading, or out of date, and that Users should not rely on Outputs without independent verification.

Customer may not (a) access the Service for the purpose of developing competing products or services, including training competing AI models, or for reselling the Service, except as expressly authorized by Atto Research; (b) reverse engineer or replicate the Service; or (c) assist any third party in doing any of the foregoing.

E. Confidentiality

E.1. Confidential Information. The parties may share information that is marked "confidential" or "proprietary," or that reasonably should be understood to be confidential ("Confidential Information"). Customer Content is Customer's Confidential Information.

E.2. Confidentiality Obligations. The receiving party may use Confidential Information only to exercise its rights and perform its obligations under these Terms and may disclose Confidential Information only to its employees, agents, and advisors who have a need to know and who are bound by confidentiality obligations at least as protective as those set forth in these Terms. The receiving party will protect Confidential Information using at least reasonable care and no less care than it uses to protect its own confidential information.

E.3. Exceptions. Confidential Information does not include information that is publicly available, information obtained from a third party without breach of a confidentiality obligation, or information independently developed without use of Confidential Information. Disclosure required by law or by court or governmental order is permitted, provided that the receiving party gives prior notice to the disclosing party to the extent practicable.

E.4. Destruction Upon Request. Upon the disclosing party's request, the receiving party will promptly destroy Confidential Information; provided that copies retained to comply with legal retention requirements or stored in automated backup systems may be retained subject to the confidentiality obligations set forth in these Terms.

G. Publicity and Disclosures

Atto Research may use Customer's name and logo to publicly identify Customer as a customer of Atto Research. However, Customer may opt out by providing notice in the separate form designated for that purpose, and any different terms set forth in an individual agreement will control. At Atto Research's reasonable request, Customer will consider in good faith (1) providing executive comments and (2) participating in joint marketing activities.

H. Fees

H.1. Payment of Fees. Customer is responsible for fees incurred under Customer's account based on the rates separately agreed by the parties. Atto Research may require prepayment.

I. Termination and Suspension

I.1. Term. These Terms will remain in effect from the Effective Date until terminated.

AI Tokens and API usage fees that have already been used are non-refundable. This Section applies as the "separate refund policy" referenced in Section I.2(a).

J. Dispute Resolution

If a dispute arises in connection with these Terms ("Dispute"), the parties will first attempt in good faith to resolve the Dispute informally. If the Dispute is not resolved within forty-five (45) days after notice of the Dispute, either party may submit the Dispute for final resolution by arbitration in Seoul, in English or Korean, under the Arbitration Rules of the Korean Commercial Arbitration Board. This Section does not limit either party's right to seek interim or conservatory relief to prevent or remedy infringement or misappropriation of rights.

K. Indemnification

K.1. Indemnification by Atto Research. Atto Research will defend and indemnify Customer, its officers, employees, successors, and assigns against any claim alleging that Customer's use of the paid Service, or Outputs generated from such use, infringes a third party's intellectual property rights.

K.2. Indemnification by Customer. Customer will defend and indemnify Atto Research against any third-party claim arising from or relating to (a) Inputs or other data provided by Customer or Users, or (b) a violation of the Usage Policy, the Service Specific Terms, or Section D.4.

K.3. Exceptions. The indemnification obligations do not apply to the extent a claim arises from the indemnified party's fraud, willful misconduct, violation of law, or breach of these Terms. Atto Research's indemnification obligation does not apply to (a) Customer's modification of the Service, (b) unauthorized combinations, (c) Inputs provided by Customer, (d) use where Customer knew or reasonably should have known of the infringement, (e) practice of a patented invention included in an Output, or (f) trademark use of an Output.

K.4. Procedure. The indemnified party will notify the indemnifying party without undue delay after becoming aware of a claim and will reasonably cooperate in the defense. The indemnifying party has the right to control the selection of counsel and the litigation, appeal, and settlement strategy; provided that any settlement that admits fault by the indemnified party or imposes affirmative obligations on the indemnified party may not be entered into without the indemnified party's consent, which consent may not be unreasonably withheld.

(c) To the maximum extent permitted by applicable law, the limitations of liability in this Section apply regardless of the form of claim, including tort and negligence, even if a party was advised in advance of the possibility of damages, the damages were foreseeable, or a non-monetary remedy fails of its essential purpose.
