End User License Agreement

Effective Date: September 1, 2026

This End User License Agreement ("Agreement") is a legally binding agreement between you ("you," "your," or "User") and Grand Charter Inc. ("Presolve," "we," "us," or "our") governing your access to and use of the Presolve software, applications, websites, tools, features, and related services (collectively, the "Services").

By creating an account, accessing, or using the Services, you acknowledge that you have read, understood, and agree to be bound by this Agreement. If you do not agree to this Agreement, you may not access or use the Services.

You may use the Services only if you are legally capable of entering into a binding agreement.

If you access or use the Services on behalf of a law firm, professional organization, company, or other entity, you represent and warrant that you have authority to bind that entity to this Agreement. In that case, "you" and "your" also refer to that entity.

Certain features of the Services may be available only to licensed attorneys or other authorized legal professionals. You are responsible for ensuring that you meet all professional, licensing, and regulatory requirements applicable to your use of the Services.

Subject to your compliance with this Agreement, Presolve grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Services solely for your internal lawful professional or business purposes, and not for the benefit of any third party other than your own clients.

The Services are licensed, not sold. Except for the limited rights expressly granted under this Agreement, Presolve and its licensors retain all right, title, and interest in and to the Services.

You may be required to create an account to use some or all of the Services.

You agree to:

• provide accurate and complete account information;
• maintain and promptly update that information;
• keep your login credentials secure and confidential;
• not share your account except as expressly permitted by Presolve; and
• promptly notify us if you believe your account has been compromised.

You are responsible for activities conducted through your account, except to the extent caused by Presolve's failure to meet its own security obligations.

You may use the Services only for lawful purposes and in accordance with this Agreement.

You may not:

• copy, modify, distribute, sell, lease, sublicense, or commercially exploit the Services except as expressly authorized by Presolve;
• reverse engineer, decompile, disassemble, or attempt to derive the source code or underlying models, systems, or algorithms of the Services, except where applicable law expressly permits such activity;
• circumvent or interfere with security, authentication, rate limits, access controls, or technical restrictions;
• access the Services using unauthorized automated means;
• introduce malware, malicious code, or other harmful material;
• use the Services to violate applicable law, court rules, professional obligations, or the rights of another person;
• impersonate another person or misrepresent your identity, credentials, licensure, or affiliation;
• use the Services in a manner that could damage, disable, overburden, or impair Presolve's systems;
• use the Services, or any output generated through them, to develop, train, or improve a competing product, model, or service;
• publish benchmarks, performance testing, or comparative analyses of the Services without our prior written consent; or
• assist another person in doing any of the foregoing.

Presolve provides technology and related services. Presolve is not a law firm and does not provide legal advice or legal representation. Presolve is not a lawyer referral service and does not share in legal fees.

You remain solely responsible for your professional services and for determining whether and how to use information made available through the Services.

If you are an attorney or legal professional, you are solely responsible for:

• verifying your eligibility, licensing status, and authority to practice;
• complying with applicable rules of professional conduct, ethics rules, court rules, and other legal obligations;
• complying with rules governing advertising, solicitation, referral arrangements, and fee-sharing with nonlawyers;
• conducting appropriate conflicts checks;
• determining whether to accept, reject, or continue any client representation;
• establishing and maintaining attorney-client relationships;
• complying with duties relating to competence, confidentiality, privilege, supervision, communication, recordkeeping, advertising, solicitation, and fee arrangements;
• independently reviewing information, documents, recommendations, summaries, or other materials provided through the Services; and
• exercising your own professional judgment.

Nothing provided through the Services should be treated as a substitute for your independent legal analysis or professional judgment.

The Services may facilitate communications or introductions between attorneys, prospective clients, existing clients, service providers, or other third parties.

Unless expressly stated otherwise, Presolve does not guarantee:

• the accuracy or completeness of information supplied by a prospective client or third party;
• that any prospective client will retain you;
• that any matter will result in a particular outcome or amount of fees;
• the identity, creditworthiness, intentions, or suitability of any person using the Services; or
• that a particular matter is appropriate for your practice.

You are responsible for conducting your own evaluation and due diligence before entering into any professional or commercial relationship.

You may submit, upload, transmit, store, or otherwise provide information, documents, communications, files, or other material through the Services ("User Content").

As between you and Presolve, you retain ownership of your User Content.

You grant Presolve a limited license to host, process, transmit, reproduce, and otherwise use User Content as reasonably necessary to operate, maintain, secure, improve, and provide the Services, and to sublicense these rights to service providers and subprocessors acting on our behalf solely for these purposes, in each case subject to applicable law and our Privacy Policy.

Presolve may create and use aggregated or de-identified data derived from use of the Services, provided that such data does not identify you, your clients, or any individual. Our use of User Content for model training or product development, if any, is described in our Privacy Policy or an applicable Order Form.

You represent and warrant that you have all rights, permissions, and lawful bases necessary to provide User Content to Presolve and to authorize its processing as contemplated by this Agreement.

The Services may allow you to process confidential, privileged, personal, or otherwise sensitive information.

You are responsible for determining whether use of the Services for particular information is consistent with your legal and professional obligations.

You must not provide information through the Services unless you are authorized to do so.

Presolve will handle information submitted through the Services in accordance with applicable agreements, policies, and laws, including our Privacy Policy.

Nothing in this Agreement is intended to waive any attorney-client privilege, work-product protection, or other applicable legal protection.

Certain portions of the Services may use artificial intelligence, machine learning, automated processing, or third-party AI technologies.

Outputs generated by automated systems may be incomplete, inaccurate, outdated, or inappropriate for a particular situation.

You agree that you will not rely on automated output as your sole basis for making legal, professional, ethical, or other consequential decisions. You are responsible for independently reviewing and verifying outputs before using or communicating them.

You are responsible for verifying any citations, authorities, quotations, or factual assertions contained in automated output before relying on, filing, submitting, or communicating them.

Presolve does not guarantee that automated outputs will be accurate, complete, unique, or suitable for any specific purpose.

The Services may integrate with or link to products and services provided by third parties.

Your use of third-party services may be subject to separate terms and privacy policies established by those third parties.

Presolve does not control and is not responsible for third-party services, except to the extent required by applicable law.

Certain Services may require payment of fees.

If you purchase a paid product or subscription, you agree to pay all applicable fees, charges, and taxes disclosed to you at the time of purchase or otherwise agreed between you and Presolve.

Subscription fees, renewal terms, cancellation policies, and other commercial terms may be described in an order form, pricing page, statement of work, or other written agreement presented to you or executed between the parties (each, an "Order Form").

In the event of a conflict between this Agreement and a separately executed written agreement between you and Presolve governing the Services, the separately executed agreement will control with respect to the conflicting terms.

The Services, including their software, designs, interfaces, text, graphics, logos, trademarks, workflows, databases, and other content provided by Presolve, are owned by or licensed to Presolve and are protected by intellectual property and other laws.

Except for the limited license granted under this Agreement, no rights in the Services are transferred to you.

"Presolve," associated logos, and other Presolve marks are trademarks or service marks of Presolve or its affiliates. You may not use them without prior written permission.

If you provide ideas, suggestions, recommendations, or other feedback relating to the Services, you grant Presolve the right to use that feedback without restriction or compensation to you.

This provision does not transfer ownership of your User Content to Presolve.

Presolve may update, modify, add, suspend, or discontinue features of the Services from time to time.

We may provide software updates automatically where appropriate.

Presolve does not guarantee that any particular feature or functionality will remain available indefinitely.

Presolve may make features, products, or functionality available on a beta, trial, preview, evaluation, or early-access basis ("Beta Features").

Beta Features are provided "as is" and "as available," may be modified or discontinued at any time, and are not subject to any service level, support, uptime, or availability commitment.

Beta Features may contain errors or defects and may not function as intended. You use Beta Features at your own risk and remain responsible for independently reviewing and verifying any output or result.

Our collection, use, and disclosure of personal information in connection with the Services are described in our Privacy Policy and any other applicable privacy notices or agreements.

By using the Services, you acknowledge that you have reviewed the applicable Privacy Policy.

You may stop using the Services at any time.

Presolve may suspend or terminate your access to the Services if:

• you materially violate this Agreement;
• your use of the Services creates a security, legal, regulatory, or operational risk;
• required by law or a governmental authority;
• you fail to pay applicable fees; or
• the Services or relevant portion of the Services are discontinued.

Where reasonably practicable, Presolve may provide notice before suspension or termination.

Upon termination, the license granted under this Agreement ends immediately.

User Content following termination. Following termination, Presolve may make User Content available for export for a limited period, after which we may delete it. We may retain User Content as required by law, for backup and disaster recovery purposes, or as otherwise described in our Privacy Policy or an applicable Order Form. You are responsible for retrieving and retaining any User Content necessary to satisfy your professional, client-file, or recordkeeping obligations.

Termination does not entitle you to a refund except as required by applicable law or as expressly provided in an applicable Order Form.

Provisions that by their nature should survive termination will remain in effect, including the sections titled User Content; Confidentiality and Sensitive Information; Fees and Payment (as to amounts accrued before termination); Intellectual Property; Feedback; Disclaimer of Warranties; Limitation of Liability; Indemnification; Governing Law and Dispute Resolution; and General Terms.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE."

PRESOLVE AND ITS AFFILIATES, LICENSORS, AND SERVICE PROVIDERS DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, RELIABILITY, AND AVAILABILITY.

PRESOLVE DOES NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE FROM HARMFUL COMPONENTS, OR THAT INFORMATION OR OUTPUTS PROVIDED THROUGH THE SERVICES WILL BE ACCURATE OR COMPLETE.

Some jurisdictions do not allow certain warranty disclaimers, so portions of this Section may not apply to you.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, PRESOLVE AND ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, LICENSORS, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, BUSINESS, DATA, GOODWILL, OR BUSINESS OPPORTUNITIES, ARISING OUT OF OR RELATED TO THE SERVICES OR THIS AGREEMENT.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, PRESOLVE'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICES OR THIS AGREEMENT WILL NOT EXCEED THE GREATER OF:

1. THE AMOUNT YOU PAID TO PRESOLVE FOR THE SERVICES DURING THE TWELVE MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM; OR
2. ONE HUNDRED U.S. DOLLARS ($100).

The limitations in this Section apply regardless of the theory of liability and even if Presolve has been advised of the possibility of such damages.

Some jurisdictions do not permit certain limitations of liability, so some portions of this Section may not apply to you.

To the extent permitted by applicable law, you agree to defend, indemnify, and hold harmless Presolve and its affiliates, officers, directors, employees, and agents from claims, damages, losses, liabilities, judgments, costs, and expenses, including reasonable attorneys' fees, arising out of or relating to:

• your misuse of the Services;
• your violation of this Agreement;
• your violation of applicable law or professional obligations;
• your professional services or attorney-client relationships;
• your User Content; or
• your infringement or violation of the rights of another person.

Procedure. Presolve will promptly notify you of any claim subject to indemnification and permit you to control the defense and settlement of that claim, provided that no settlement imposing liability on Presolve or admitting fault by Presolve may be entered without our prior written consent. You will provide reasonable cooperation at your expense. Presolve may participate in the defense with counsel of its own choosing at its own expense. A delay or failure to provide notice relieves you of your obligations only to the extent you are materially prejudiced by it.

You are responsible for complying with all laws, regulations, professional rules, and industry requirements applicable to your use of the Services.

You may not use or access the Services if doing so would cause Presolve or you to violate applicable sanctions, export-control laws, or other legal restrictions.

This Agreement will be governed by the laws of the State of New York, without regard to its conflict-of-laws principles.

Any dispute arising out of or relating to this Agreement or the Services will be resolved in the state courts located in New York County, New York or the federal court for the district encompassing New York County, New York, except where a separately executed agreement between the parties specifies a different forum or dispute-resolution procedure.

You consent to the personal jurisdiction and venue of those courts.

Each party waives, to the fullest extent permitted by applicable law, any right to a trial by jury.

Any claim arising out of or relating to this Agreement or the Services must be brought within one year after the claim accrues, except where applicable law prohibits a shorter limitations period.

Presolve may modify this Agreement from time to time.

If we make material changes, we may provide notice through the Services, by email, or through another reasonable method.

Unless otherwise stated, updated terms become effective when posted or on the effective date specified in the notice.

Your continued use of the Services after the updated Agreement becomes effective constitutes acceptance of the updated terms. If you do not agree to the updated terms, you must stop using the Services and may terminate your account before the effective date.

Presolve may provide notices to you through the Services, by email to the address associated with your account, or by another reasonable method. Notices are effective when sent or posted.

You may provide notice to Presolve at the address identified in the Contact section of this Agreement. Notices to Presolve are effective upon receipt.

You consent to receive communications from Presolve in electronic form, and you agree that electronic communications, agreements, and records satisfy any legal requirement that such communications be in writing. You agree that electronic signatures and acceptances have the same legal effect as handwritten signatures.

This Agreement, together with any policies, Order Forms, or additional terms expressly incorporated into it, constitutes the entire agreement between you and Presolve regarding its subject matter.

If any provision of this Agreement is found unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, or if modification is not possible, severed, and the remaining provisions will remain in full force and effect.

Presolve's failure to enforce a provision of this Agreement is not a waiver of its right to do so later.

You may not assign or transfer this Agreement without Presolve's prior written consent. Presolve may assign this Agreement in connection with a merger, acquisition, corporate reorganization, sale of assets, or otherwise as permitted by law.

Nothing in this Agreement creates any agency, partnership, joint venture, employment, or fiduciary relationship between you and Presolve. Each party is an independent contractor.

This Agreement is for the benefit of you and Presolve only and does not create any third-party beneficiary rights, including in any client, prospective client, or other third party.

Headings are provided for convenience only and do not affect interpretation.
