Business Supplement

VERSION 1.2 · EFFECTIVE SEPTEMBER 8, 2026 · DRAFT PENDING COUNSEL REVIEW · QUANTGPT LLC, A FLORIDA LIMITED LIABILITY COMPANY

// 1. WHO THIS BINDS

This Supplement is between QuantGPT LLC, a Florida limited liability company, 15350 N Florida Ave, Tampa, FL 33613 ("QuantGPT"), and the Organization identified at signup or in an order form ("Customer"). The individual who accepts the Terms on the Organization's behalf represents that they are authorized to do so, and Section 16.2 of the Terms applies if they are not. Customer is responsible for every person it allows to use the Service under its account ("Authorized Users"), for their compliance with the Terms and this Supplement, and for keeping the number of Authorized Users within the seats purchased.

// 2. ADMINISTRATION

• Customer designates an administrator who manages seats, keys, and access. Only Authorized Users who are employees or individual contractors of Customer, working on Customer's own internal research, may use the Service. Affiliates, clients, and third parties require their own accounts or a separate agreement.
• Seats, keys, and logins are for named individuals and may not be shared or pooled. Customer will remove access promptly when an Authorized User leaves.
• Customer is responsible for all fees for all seats, whether or not used.

// 3. SUBSCRIBER STATUS

Because Customer uses Market Data in the course of business, Customer and its Authorized Users are Professional subscribers under Section 8.4 of the Terms unless we agree otherwise in writing. Data fees, entitlements, and reporting for Professional use may differ from consumer plans and are set out in the applicable order form. Customer will provide any subscriber information our data providers require and will notify us of changes.

// 4. CONFIDENTIALITY

Section 17 of the Terms applies to Customer and every Authorized User. In addition, Customer will: limit access to Confidential Information to Authorized Users who need it; ensure each Authorized User is bound by written confidentiality obligations at least as protective as Section 17; be responsible for any breach by an Authorized User or former Authorized User; and notify us within 48 hours of learning of any unauthorized use or disclosure of Confidential Information or Market Data. We will treat Customer's non-public usage data, study definitions, and business information that Customer identifies as confidential with the same care, subject to the Privacy Policy and our obligations to data providers.

// 5. NON-COMPETITIVE USE COVENANT

This covenant restricts what Customer does with the Service. It does not restrict Customer's freedom to be in any business, to use its own data, or to develop products from sources other than the Service.

5.1 Covenant

During the term of Customer's subscription and for twelve (12) months after it ends, Customer will not, and will not permit any Authorized User, affiliate, or third party acting for it to, use the Service, the QuantGPT Materials, Market Data obtained through the Service, Research Output, or Confidential Information to design, develop, train, benchmark, validate, market, or operate any product, service, model, or dataset that competes with the Service or replicates a material part of its functionality, content, methodology, or data, anywhere the Service is offered.

5.2 Legitimate business interest

Customer acknowledges that this covenant protects QuantGPT's trade secrets and valuable confidential business information within the meaning of Section 542.335(1)(b) of the Florida Statutes, including its non-public methodology, factor definitions, engine design, data structures, and licensed data arrangements, to which Customer receives privileged access through the Service; that the restraint is reasonably necessary to protect those interests; and that its duration, scope, and geography are reasonable given that the Service is offered online without geographic limit and that the protected information retains value well beyond twelve months.

5.3 Independent development

Nothing in this Section prevents Customer from developing products using general industry knowledge, publicly available information obtained from sources other than the Service, or data Customer licenses directly from data providers, provided that no Confidential Information, QuantGPT Materials, or Market Data obtained through the Service is used and that the people doing the work have not had access to Confidential Information, or Customer maintains documented safeguards that prevent its use.

5.4 Non-solicitation of personnel

During the term of Customer's subscription and for twelve (12) months after it ends, Customer will not, directly or through others, solicit for employment or engagement, or hire or engage, any employee or individual contractor of QuantGPT who worked on the Service and with whom Customer had contact through the Service or through its relationship with QuantGPT, without QuantGPT's written consent. A general advertisement not targeted at QuantGPT personnel is not solicitation. Customer acknowledges that this restriction protects QuantGPT's confidential information and the extraordinary and specialized training of its personnel, each a legitimate business interest under Section 542.335(1)(b) of the Florida Statutes, and that its scope and duration are reasonable.

5.5 Reformation

If a court finds any covenant in this Section 5 broader than necessary, it will be enforced to the maximum extent permitted and modified as required by Section 542.335(1)(c) of the Florida Statutes.

// 6. NO RIGHT TO BUILD ON THE DATA

This Supplement grants Customer the right to use the Service for its own internal research. It grants no right to redistribute Market Data or Research Output, to embed either in any product or service offered to others, to resell access, or to build derivative datasets, models, or products. Customer that wants any of those rights must sign a separate Data License Agreement, negotiated individually, which may include license fees, revenue sharing, audit rights, and obligations that survive termination. Any such use without a signed Data License Agreement is a breach of Sections 8 and 15 of the Terms and of this Supplement, and Section 15.5 of the Terms applies.

// 7. AUDIT

On at least ten (10) business days notice, no more than once in any twelve-month period, or at any time on reasonable suspicion of breach, QuantGPT or an independent auditor bound by confidentiality may verify Customer's compliance with the Terms and this Supplement by reviewing usage records, access logs, seat assignments, and, where relevant, the systems into which Service output has been placed. Audits are conducted remotely where possible and in a manner that minimizes disruption. Customer will cooperate and provide reasonable access and information. If an audit reveals a material breach, Customer will pay the cost of the audit in addition to any other remedy.

// 8. RECORDS AND CERTIFICATION

Customer will keep accurate records of Authorized Users and of any export or sharing of Research Output for at least two years, and will provide, on request and at termination, a written certification signed by an officer that Customer has complied with Sections 8, 15, and 17 of the Terms and Sections 4 through 6 of this Supplement and has destroyed all Market Data and Confidential Information.

// 9. LIQUIDATED DAMAGES AND REMEDIES

Section 15.5 of the Terms applies to Customer, and Customer acknowledges that, given its access to Professional-level entitlements and multiple seats, the liquidated amounts stated there are a reasonable pre-estimate of QuantGPT's minimum loss from a breach. Customer's liability for breach of Sections 4 through 6 of this Supplement and Sections 8, 15, and 17 of the Terms is not subject to the cap in Section 21 of the Terms.

// 10. GOVERNMENT AND REGULATED CUSTOMERS

If Customer is a government entity, or is subject to regulations that require modifications to these terms, Customer will notify us before use and we will agree on appropriate modifications in an order form. Customer remains responsible for compliance with its own regulatory obligations, including any obligations relating to the use of third-party market data.

// 11. TERM AND ORDER OF PRECEDENCE

This Supplement lasts as long as Customer's subscription and, for Sections 4, 5, 8, and 9, for the periods stated in them after it ends. A signed order form or Data License Agreement governs over this Supplement; this Supplement governs over the Terms for organizational use; the Terms govern everything else.
