MBSE CONSULTING SOFTWARE LICENSE Version 1.0, August 2026 https://licenses.mbseconsulting.com/software/1.0.txt TERMS AND CONDITIONS FOR USE AND DISTRIBUTION OF THE LICENSED MATERIAL This License governs the products and the deliverables that MBSE Consulting supplies to its clients. MBSE Consulting licenses that material and retains ownership of it. This License grants perpetual rights, it does not terminate, and it imposes no obligation on the models, data, or documents that a licensee creates with the material. This License states in full the terms on which a recipient holds the Licensed Material. A recipient need not hold any other agreement with Licensor to rely on it. 1. Definitions. "Licensor" means MBSE Consulting, the owner of the Licensed Material. "Product" means material that Licensor develops for supply to more than one client, and supplies to a Licensee in the form and version that Licensor states, together with its accompanying notices and Documentation. A Product may comprise several files of different kinds, including profiles, model libraries, code, and archives, which together form one Product. "Deliverable" means material that Licensor develops for a single Licensee under an Engagement Contract, and delivers to that Licensee in the version that Licensor states, together with its accompanying notices and Documentation. A Deliverable may contain profiles, model libraries, templates, samples, custom diagrams, perspectives, plugins, descriptors, and any other asset that a modeling tool installs from it, in any combination. A Deliverable may package one or more Products, and may package material that a third party owns. "Licensed Material" means the Products and the Deliverables. "Source Form" means the preferred form of the Licensed Material for making modifications to it, including source code, build scripts, and model files that a modeling tool opens and edits directly. "Documentation" means the user and technical documentation that Licensor supplies with the Licensed Material. "Engagement Contract" means the consulting agreement, statement of work, order form, proposal, or other written agreement under which Licensor supplies the Licensed Material to a Licensee. "Licensee" means the legal entity to which Licensor supplies the Licensed Material under an Engagement Contract. "Group Entity" means an entity that Licensee controls, that controls Licensee, or that stands under common control with Licensee, where control means beneficial ownership of more than fifty percent of the voting shares. "Programme Participant" means an entity that receives Licensed Material from Licensee or from a Group Entity for the purpose of work that entity performs for Licensee or for that Group Entity. "Modification" means a change that Licensee makes to the Source Form of Licensed Material, and any extension, addition, or correction that Licensee makes to it. "Client Model" means the models, data, documents, code, and other content that Licensee creates using the Licensed Material, and any profile, library, or other artifact that Licensee authors which references, extends, or calls the Licensed Material without altering it. Client Model excludes Modifications. "Controlled Data" means information that falls in any category of the list of controlled items of any applicable export control regulation, or that stands subject to cybersecurity regulatory requirements on the information technology systems used for its storage or transfer. Whenever the context requires, the terms herein apply equally to the singular and plural forms of the terms defined. 2. Acceptance, Form of Grant, and Precedence. 2.1 Public grant. Licensor grants this License directly to every person who lawfully receives Licensed Material, and not only to the Licensee that first received it. A recipient accepts this License by installing, copying, accessing, or using the Licensed Material. A recipient that does not accept this License holds no right to install, copy, access, or use it. 2.2 Recipients other than Licensee. Where this License grants a right to Licensee, a Group Entity or a Programme Participant holds that right to the extent Section 4 states. 2.3 Precedence. Where Licensee and Licensor hold a separate written agreement that governs the same subject matter, that agreement prevails over this License to the extent of any conflict, and only as between Licensor and that Licensee. This License continues to govern every other recipient of the Licensed Material without alteration. 2.4 Products within a Deliverable. Where Licensor packages a Product with a Deliverable, the terms of this License that apply to a Product govern that Product. In particular, a permission to modify a Deliverable does not extend to a Product packaged with it. 2.5 Business transaction. This License governs a transaction between businesses. A recipient enters it for purposes relating to its trade, business, craft, or profession, and it is not a consumer contract. 3. Grant of License. 3.1 Scope. On payment in full of the amounts that the Engagement Contract states, Licensor grants Licensee a perpetual, irrevocable, non-exclusive, royalty-free, worldwide license to: (a) install and use the Licensed Material, without limit on the number of users, machines, or installations within Licensee and its Group Entities; (b) use the Licensed Material to create, read, edit, and maintain Client Models, for as long as Licensee holds them. Where a Client Model requires Licensed Material to be installed in order to be read or edited, this right extends to installing and running that Licensed Material for that purpose, without limit of time; (c) modify the Licensed Material to the extent Section 7 permits; and (d) reproduce and distribute the Licensed Material, in the form Licensor supplied it or as Section 7 permits Licensee to modify it, as a component of Client Models or of Licensee's own work, to the recipients that Section 4 identifies. 3.2 Copies. Licensee may make any number of copies of the Licensed Material that the rights in Section 3.1 require, including copies for backup and disaster recovery. Every copy carries this License and all proprietary notices unchanged. 3.3 Application is not modification. Applying the Licensed Material, instantiating its stereotypes, invoking its interfaces, configuring it, authoring a separate profile that references or specializes it, and creating Client Models with it do not constitute modification of the Licensed Material under Section 6 or Section 7. 3.4 Versions. This License covers the version of the Licensed Material that Licensor supplied. Licensor owes no obligation to supply any later version. Where Licensor supplies a later version, the license that Licensor publishes for that version governs it. 3.5 Patents. Licensor grants Licensee, its Group Entities, and Programme Participants a perpetual, irrevocable, non-exclusive, royalty-free license under every patent claim that Licensor owns or controls and that the Licensed Material as supplied necessarily infringes, to exercise the rights that Section 3.1 grants. Licensor shall not assert any such claim against a recipient in respect of that exercise. 4. Extension to Group Entities and Programme Participants. 4.1 Group Entities. Every Group Entity holds the rights in Section 3.1 on the same terms as Licensee. Licensee remains responsible for each Group Entity's compliance with this License. 4.2 Programme Participants. Every Programme Participant holds the rights in Sections 3.1(a) and 3.1(b), and holds the right in Section 3.1(d) to the extent distribution serves the work it performs for Licensee, provided that the Programme Participant uses the Licensed Material only for that work. 4.3 Limit. This Section grants no right to distribute Licensed Material to any person other than a Group Entity or a Programme Participant. This Section does not restrict the distribution of Client Models, which Section 5 governs. 5. Ownership of Licensed Material and Client Models. 5.1 Licensed Material. Licensor licenses the Licensed Material and does not sell it. Licensor and its licensors retain all right, title, and interest in and to the Licensed Material, the Documentation, and every intellectual property right in them, in every version that Licensor supplies. Licensor reserves every right that this License does not expressly grant. Licensee acquires no right in Licensor's trademarks, service marks, or trade names. 5.2 Client Models. Licensee owns every Client Model outright. Licensor claims no right, title, or interest in any Client Model, and asserts no obligation over it by reason of the Licensed Material that it applies, references, calls, or depends on. Licensee may use, modify, license, and distribute Client Models without restriction under this License, and without notice to Licensor. Where a Client Model contains Licensed Material, that Licensed Material remains subject to this License; the remainder of the Client Model does not. 5.3 No responsibility for Client Models. Licensor exercises no control over Client Models and assumes no responsibility or liability for them, for their content, or for any decision that any person takes on the basis of them. 5.4 Feedback. Where a recipient supplies Licensor with a suggestion, an enhancement request, or other feedback concerning the Licensed Material, Licensor may use and exploit that feedback without restriction and without obligation to that recipient. 6. Restrictions. 6.1 General. Except as Section 3, Section 7, or Section 12 expressly permits, a recipient shall not, and shall not permit any other person to: (a) modify, adapt, translate, or create derivative works of the Licensed Material; (b) reverse engineer, decompile, or disassemble the Licensed Material, or otherwise attempt to derive its Source Form from an object-code form; (c) distribute, publish, sell, rent, lease, lend, sublicense, or otherwise transfer the Licensed Material other than under Sections 3.1(d) and 4; (d) remove, obscure, or alter any copyright, trademark, license, or other proprietary notice in or on the Licensed Material; (e) use the Licensed Material, or information derived from it, to develop an artifact intended to substitute for or compete with it; or (f) use the Licensed Material to develop, deliver, or maintain a modeling framework, or to provide framework development services, for any person other than Licensee, its Group Entities, and, in the case of a Programme Participant, the Licensee for which it performs work. 6.2 Material-specific terms. The Engagement Contract states any term specific to an item of Licensed Material, in addition to or in variation of this Section. 6.3 Mandatory law. Nothing in this Section restricts an act that mandatory applicable law permits and does not allow a contract to exclude, including decompilation for interoperability under Article 6 of Directive 2009/24/EC and equivalent provisions of the law of other jurisdictions. Before exercising such a right, the recipient shall request the interoperability information it needs from Licensor, and Licensor shall supply that information on reasonable terms within a reasonable time. 7. Modifications, Extensions, and Interfaces. 7.1 Deliverables. Where Licensor supplies a Deliverable, or a part of a Deliverable, to Licensee in Source Form, Licensee may make Modifications to it for the purpose of using and maintaining it for Licensee, its Group Entities, and its Programme Participants. Section 6.1(a) does not apply to that material to that extent. 7.2 Products, and material supplied in object-code form. Licensee shall not modify a Product, in whatever form Licensor supplies it, and shall not modify any part of a Deliverable that Licensor supplies only in object-code form. Licensee shall run such material at the version that Licensor supplied. This Section applies to a Product whose files a modeling tool opens and edits directly, including a profile, as it applies to a Product supplied in object-code form. 7.3 Ownership of Modifications. Licensee owns the Modifications that it makes. A Modification exists only as a modification of Licensed Material that Licensor owns. Licensee may therefore use and distribute a Modification only as part of the Licensed Material and under this License, and shall not extract, distribute, sublicense, or otherwise exploit a Modification separately from the Licensed Material. Licensor acquires no right in a Modification, and may not use a Modification without Licensee's consent. 7.4 Restrictions travel. Section 6 applies to Licensed Material as modified, on the same terms as it applies to the Licensed Material that Licensor supplied. 7.5 Extension by a separate artifact. Nothing in this Section restricts Licensee from authoring its own profile, library, or other artifact that references the Licensed Material, or that defines elements generalizing or specializing its stereotypes, in the manner in which the Licensed Material itself extends the modeling language it builds on, provided that Licensee does not alter the Licensed Material. Such an artifact is a Client Model, and Section 5.2 governs it. Where that artifact depends on the Licensed Material, a recipient of the artifact requires the Licensed Material under this License in order to use it. 7.6 Interfaces. Licensee may develop code and model content that calls the documented interfaces of the Licensed Material. Such code and content is a Client Model, and Section 5.2 governs it. Code does not become a Modification, or a derivative work of the Licensed Material, by reason of calling its interfaces or linking against it. 7.7 No support for modified material. Licensor owes no obligation in respect of Licensed Material that Licensee has modified, and Section 15 applies to it without qualification. 8. Attribution. Every recipient shall preserve, in every copy and in every distribution of Licensed Material, this License, every notice in the source or header of a file within the Licensed Material, and the content of any NOTICE file that accompanies it. Licensee may state in a Client Model that the Client Model depends on the Licensed Material. This License grants no other right in Licensor's trademarks, service marks, or trade names. 9. Third-Party Material. Licensed Material may incorporate or be distributed with material that a third party owns, including any archive placed on the runtime classpath of a plugin. Where Licensor supplies such material, Licensor identifies it and its license terms in the material that accompanies the Licensed Material. Those license terms govern that material and prevail over this License to the extent of any conflict. Licensor grants no rights in third-party material beyond what those terms grant, and disclaims all warranties and liability for it. 10. No Confidentiality Obligation. This License imposes no confidentiality obligation on the Licensed Material, on its structure or organization, or on the Documentation. This Section does not affect any confidentiality obligation that an Engagement Contract or a separate agreement imposes on other material. 11. No Support Obligation. This License grants no right to support, maintenance, defect correction, updates, or new versions. Licensor supplies those only where an Engagement Contract or a separate agreement states so, and on the terms it states. 12. Source Release. 12.1 Trigger. A Release Event occurs where Licensor enters insolvency, liquidation, or an equivalent proceeding, where Licensor is dissolved, or where Licensor gives Licensee written notice that it discontinues an item of Licensed Material. 12.2 Effect. On a Release Event, Licensor shall supply Licensee, on written request, with the Source Form of the affected Licensed Material and with the build instructions that a competent engineer requires to compile it. Licensee may then modify that Licensed Material for the purpose of maintaining it, and Sections 6.1(a), 6.1(b), and 7.2 cease to apply to it to that extent. 12.3 Scope. Section 12.2 grants no right to distribute the Source Form of Licensed Material, or a Modification of it, other than under Sections 3.1(d) and 4. Sections 6.1(c), 6.1(d), 6.1(e), and 6.1(f), Section 7.3, and Section 8 continue to apply. 12.4 Replacement. Where Licensor discontinues an item of Licensed Material and supplies a replacement under a later Engagement Contract, Licensee may exercise Section 12.2 in respect of the discontinued item whether or not it takes the replacement. 13. Export Control and Sanctions. Every recipient shall comply with all applicable export control, import, and sanctions laws, including Regulation (EU) 2021/821 and the sanctions regulations of the European Union and of any other jurisdiction that applies. No recipient shall export, re-export, transfer, or make Licensed Material available to any person, entity, or destination that those laws restrict, or use Licensed Material for any prohibited end use. Unless a separate agreement provides for it, neither Licensor nor any recipient shall disclose or exchange Controlled Data with the other. A recipient shall not include Controlled Data in any material it submits to Licensor, including any model, log, or file submitted with a defect report. 14. Disclaimer of Warranty. THE LICENSED MATERIAL IS PROVIDED "AS IS", WITHOUT WARRANTY OR CONDITION OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. LICENSOR DISCLAIMS ALL IMPLIED WARRANTIES AND CONDITIONS OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY, AND NON-INFRINGEMENT. LICENSOR DOES NOT WARRANT THAT THE LICENSED MATERIAL WILL OPERATE UNINTERRUPTED OR ERROR-FREE, THAT IT WILL MEET ANY RECIPIENT'S REQUIREMENTS, OR THAT IT WILL INTEROPERATE WITH ANY PARTICULAR VERSION OF ANY THIRD-PARTY SOFTWARE. EVERY RECIPIENT BEARS SOLE RESPONSIBILITY FOR DETERMINING THE SUITABILITY OF THE LICENSED MATERIAL FOR ITS PURPOSES, FOR VALIDATING ANY MODEL, ANALYSIS, OR RESULT THAT IT PRODUCES WITH THE LICENSED MATERIAL, AND FOR ANY DECISION IT TAKES ON THE BASIS OF THAT RESULT. This Section does not affect any warranty that an Engagement Contract states in respect of the services that Licensor performs. 15. Limitation of Liability. 15.1 Excluded loss. TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR SHALL NOT BE LIABLE FOR ANY INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL LOSS, NOR FOR ANY LOSS OF PROFIT, REVENUE, BUSINESS, ANTICIPATED SAVING, DATA, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH THIS LICENSE OR THE LICENSED MATERIAL, WHETHER IN CONTRACT, TORT, OR OTHERWISE, AND WHETHER OR NOT LICENSOR WAS ADVISED OF THE POSSIBILITY OF THAT LOSS. 15.2 Cap. TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR IN CONNECTION WITH THIS LICENSE AND THE LICENSED MATERIAL SHALL NOT EXCEED FIFTY THOUSAND EUROS PER ENGAGEMENT CONTRACT. THAT AMOUNT IS A SINGLE AGGREGATE LIMIT FOR ALL CLAIMS BY LICENSEE, ITS GROUP ENTITIES, AND ITS PROGRAMME PARTICIPANTS TOGETHER, WHENEVER THE EVENT GIVING RISE TO A CLAIM OCCURS. THE EXISTENCE OF MULTIPLE CLAIMS OR MULTIPLE CLAIMANTS DOES NOT ENLARGE IT. NO ITEM OF LICENSED MATERIAL NEED CARRY A SEPARATE PRICE FOR THIS SECTION TO APPLY. 15.3 Single cap. Where the Engagement Contract states a limit on Licensor's liability, that limit and the limit in Section 15.2 form one aggregate limit, not two. Amounts recovered under either count toward both. 15.4 Carve-out. Nothing in this License excludes or limits any party's liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, for gross negligence or wilful misconduct, or for any other liability that law does not permit a contract to exclude or limit. 15.5 No limit on recipient obligations. This Section limits Licensor's liability only. It does not limit any recipient's liability under Section 6, Section 7, Section 8, or Section 13, or any payment obligation under an Engagement Contract. 15.6 No double recovery. Where the same facts give rise to liability under both this License and another agreement between the parties, a recipient may not recover more than once for the same loss. 15.7 Allocation of risk. The parties agree that the disclaimer in Section 14 and the limitations in this Section allocate risk between them, that they reflect the terms on which Licensor supplies the Licensed Material, and that they apply even where a limited remedy fails of its essential purpose. 16. No Termination. 16.1 The rights in Sections 3.1(a), 3.1(b), and 3.1(c) are irrevocable and do not terminate, whether for breach of this License, on expiry or termination of an Engagement Contract, or otherwise. Licensor retains its remedies in damages and in injunctive relief for any breach. 16.2 Where a recipient materially breaches Section 6, Section 7, or Section 8, Licensor may suspend that recipient's right under Section 3.1(d) on written notice. The suspension ends when the recipient remedies the breach. A suspension does not affect any other recipient. 16.3 Sections 5 through 19 survive any suspension under Section 16.2 and any expiry or termination of an Engagement Contract. 17. Governing Law and Jurisdiction. 17.1 Governing law. The laws of the Hellenic Republic govern this License and any dispute or claim arising out of or in connection with it, including any non-contractual dispute or claim, excluding its conflict-of-laws rules and excluding the United Nations Convention on Contracts for the International Sale of Goods. 17.2 Jurisdiction. The courts of Athens, Greece hold exclusive jurisdiction over any dispute arising out of or in connection with this License. The parties intend this Section as an exclusive choice of court agreement within the meaning of the Hague Convention of 30 June 2005 on Choice of Court Agreements. 17.3 Arbitration. Licensor and a Licensee may agree in writing, in an Engagement Contract or otherwise, that arbitration replaces Section 17.2 as between them. That agreement binds the Group Entities and Programme Participants of that Licensee. 17.4 Injunctive relief. Section 17.2 does not prevent Licensor from seeking injunctive or other interim relief in any court of competent jurisdiction to protect its intellectual property. 18. General. 18.1 Entire agreement. This License, together with the third-party terms that Section 9 identifies, states the entire agreement between Licensor and each recipient on the rights in the Licensed Material. Section 2.3 governs any conflict with an Engagement Contract. 18.2 Assignment. A recipient may transfer its rights under this License only together with the Client Models to which they relate, and only to a successor to the business or the assets of which those Client Models form part, on written notice to Licensor. Any other assignment, novation, or transfer requires Licensor's prior written consent, and any attempt to do so without that consent is void. Licensor may assign this License to a Group Entity of Licensor or to a successor to its business or assets. 18.3 No waiver. A party's failure or delay in exercising a right under this License does not waive that right, and a single or partial exercise does not prevent any further exercise. 18.4 Severability. Where a court holds a provision of this License invalid or unenforceable, that provision applies to the maximum extent the law permits and the remaining provisions continue in full force. 18.5 Notices. A notice under this License takes effect when delivered in writing to the address the Engagement Contract states, or, absent an Engagement Contract, to the contact address that Licensor publishes. 18.6 Force majeure. Neither party bears liability for a failure to perform, other than a payment obligation, caused by an event beyond its reasonable control. 18.7 Language. The English text of this License governs. A translation serves convenience only. 19. Identification of Licensed Material. Licensor identifies each item of Licensed Material, its version, and whether it is a Product or a Deliverable, in the material that accompanies it. Licensor records the version of every item of Licensed Material that it supplies to a Licensee in the delivery record for the Engagement Contract. The version so recorded is the version that Section 3.4 covers and, where Section 7.1 permits Modifications, the baseline from which a Modification is measured. END OF TERMS AND CONDITIONS APPENDIX: FILE HEADER NOTICE Licensor attaches the following notice to files within the Licensed Material, inside a comment syntax that the file format supports. Section 6.1(d) requires every recipient to preserve it. Copyright [yyyy] MBSE Consulting. All rights reserved.
