RIGLESS CONTRIBUTOR LICENSE AGREEMENT Version 1.0, 6 September 2026 Thank you for your interest in contributing to software published by Rigless Labs under the Rigless License ("Published Source"). Because the Published Source is not open source, Rigless Labs must hold sufficient rights in every contribution to license it to others under the Rigless License and under any other terms it chooses. This agreement gives Rigless Labs those rights while you keep ownership of your work. It applies to every Contribution you make, now or later, to any Published Source. You may withdraw it for future Contributions by written notice; Contributions made before the notice remain covered. Sign by adding the line I have read and agree to the Rigless Contributor License Agreement, version 1.0. to the description of your first merge request, or by emailing that sentence with your full name to wezley.sherman@riglesslabs.com. A merge request that contains that line is a signature by the individual who opened it. If you contribute on behalf of an employer or other entity, an authorized signatory of that entity must sign the Entity Schedule below before the Contribution is accepted. 1. DEFINITIONS "You" means the individual or entity making a Contribution, together with any Affiliates that own or control the Contribution or any right in it. "Contribution" means any original work of authorship, including code, models, data, documentation, and modifications or additions to existing work, that you intentionally submit to Rigless Labs for inclusion in the Published Source, in any form, including through a merge request, an issue, an email, or any other communication with Rigless Labs, unless conspicuously marked "Not a Contribution." "Affiliate" has the meaning given in the Rigless License. 2. COPYRIGHT LICENSE You grant Rigless Labs and its successors a perpetual, worldwide, non-exclusive, irrevocable, royalty-free, fully paid, transferable license, with the right to sublicense through multiple tiers, to reproduce, prepare derivative works of, publicly display, publicly perform, distribute, and otherwise exploit your Contributions and derivative works of them, in any form and under any license terms, including the Rigless License, proprietary terms, and open-source licenses. To the extent moral rights or similar rights cannot be licensed, you waive them and agree not to assert them against Rigless Labs or its licensees. 3. PATENT LICENSE You grant Rigless Labs and its successors, and to recipients of software distributed by Rigless Labs, a perpetual, worldwide, non-exclusive, irrevocable (except as stated below), royalty-free, fully paid, transferable license, with the right to sublicense through multiple tiers, to make, have made, use, offer to sell, sell, import, and otherwise transfer the Contribution alone and in combination with the work to which it was submitted, under any patent claims you own or control, now or later, that are necessarily infringed by the Contribution alone or by that combination. If you or your Affiliate institute patent litigation, including a cross-claim or counterclaim, alleging that a Contribution or the work to which it was submitted infringes a patent, every patent license granted to you under this agreement and under the Rigless License for that work terminates on the date the litigation is filed. 4. YOUR REPRESENTATIONS You represent that: (a) you are legally entitled to grant the licenses above and, if you are an individual, you are at least eighteen years old; (b) each Contribution is your original creation, or you have identified in the Contribution every part that is not, together with its author, license, and any restriction; (c) no part of a Contribution is subject to a license, agreement, or obligation, including one to an employer or client, that conflicts with this agreement; (d) if your employer or any other party has rights in intellectual property you create, that party has signed the Entity Schedule or has waived those rights for your Contributions in writing; (e) no Contribution contains material controlled under the International Traffic in Arms Regulations or the Export Administration Regulations, material confidential to any third party, material generated by copying any third party's proprietary code, or material derived from any current or former employer's proprietary information; and (f) you will notify Rigless Labs promptly if you become aware of any fact that would make these representations inaccurate. 5. NO OBLIGATION TO USE Rigless Labs is not obliged to include any Contribution in the Published Source, to credit you, or to keep any Contribution confidential. 6. OWNERSHIP AND DISCLAIMER You retain ownership of your Contributions, subject to the licenses granted here. Except for the representations in Section 4, Contributions are provided "AS IS" without warranty of any kind, and you are not required to provide support for them. To the extent permitted by law, Rigless Labs will not hold you liable for damages arising from a Contribution beyond a breach of Section 4. 7. GENERAL This agreement is governed by the laws of the State of Alabama, United States of America, excluding its conflict-of-law rules, and the state and federal courts in Madison County, Alabama have exclusive jurisdiction over any dispute arising from it. It is the entire agreement about Contributions and supersedes any prior agreement about them. If any provision is unenforceable, the remainder remains in effect. Rigless Labs may assign this agreement to a successor; you may not assign it. This agreement is written in English, and any translation is for convenience only.
