BRILLQ COMMERCIAL SOFTWARE LICENSE AGREEMENT
brillQ OPEX Benchmark: Bayesian cost-frontier benchmarking library
Version 1.1, effective 3 October 2026

IMPORTANT: READ CAREFULLY. This Commercial Software License Agreement (the
"Agreement") is a legal agreement between brillQ spółka z ograniczoną
odpowiedzialnością with its registered office in Warsaw, Poland ("brillQ",
"Licensor") and the natural or legal person that installs, copies or otherwise
uses the Software ("Licensee", "you"). By installing, copying or using the
Software you accept the terms of this Agreement. If you do not agree, do not
install or use the Software.

1. DEFINITIONS
1.1 "Software" means the brillQ OPEX Benchmark library (distributed as
    brillq-opex-benchmark and, in earlier releases, as brillq-opex-analytics and
    brillq-opex) in object and/or source form, including the Python package
    `brillq_opex`, its command-line tools, documentation, examples and any Updates
    supplied by brillQ.
1.2 "License Key" means a digitally signed key issued by brillQ that enables
    the Software's licensed mode.
1.3 "Evaluation Mode" means operation of the Software without a License Key,
    which limits every frontier estimation to the number of units stated in the
    documentation and emits an evaluation notice.
1.4 "Order" means the quotation, invoice or order form issued by brillQ that
    specifies the licensed plan, number of Authorised Users, unit limits (if
    any), term and fees.
1.5 "Authorised Users" means the employees and contractors of Licensee who are
    permitted to use the Software under the Order, within the limits it states.
1.6 "Updates" means bug fixes, patches and minor or major versions of the
    Software that brillQ makes available to Licensee under an active Order.

2. GRANT OF LICENSE
2.1 Commercial license. Subject to payment of the applicable fees and to the
    terms of this Agreement, brillQ grants Licensee a non-exclusive,
    non-transferable, non-sublicensable, worldwide license, for the term stated
    in the Order, to (a) install and use the Software on systems owned or
    controlled by Licensee, (b) permit Authorised Users to use the Software for
    Licensee's internal business purposes, including the analysis of data of
    Licensee's clients where Licensee is a consultancy or service provider, and
    (c) incorporate the Software's outputs (tables, figures, reports) in
    Licensee's own deliverables without restriction.
2.2 Evaluation license. Absent an Order, brillQ grants Licensee a
    non-exclusive, non-transferable license to use the Software in Evaluation
    Mode for internal evaluation purposes only, for a period of thirty (30) days
    from first installation. Production use, use for the benefit of third
    parties and use beyond the evaluation period require a commercial license.
2.3 Internal use includes running the Software on servers, containers or cloud
    infrastructure operated for Licensee, provided that access is limited to
    Authorised Users and the Software is not made available as a service to
    third parties.
2.4 Source code. Where brillQ supplies source code, Licensee may modify it
    solely for internal use and only for the purpose of integrating or
    adapting the Software to Licensee's environment. Modified versions remain
    Software under this Agreement; brillQ has no support obligations for
    modified code.

3. RESTRICTIONS
Except as expressly permitted in this Agreement or by mandatory law, Licensee
shall not, and shall not permit any third party to:
(a) distribute, sell, rent, lease, lend, sublicense, host or otherwise make
    the Software or any part of it (including License Keys) available to third
    parties;
(b) offer the Software, or a service whose principal functionality is provided
    by the Software, as a software-as-a-service, API or bureau service to third
    parties;
(c) remove, alter or circumvent any License Key mechanism, evaluation limit,
    proprietary notice or copyright notice;
(d) reverse engineer, decompile or disassemble the Software except to the
    extent that applicable law expressly permits such activity notwithstanding
    this limitation;
(e) use the Software to develop a competing product or to train a statistical
    model whose purpose is to replicate the Software;
(f) publish benchmark or comparison results concerning the Software without
    identifying the version used and the settings applied.

4. LICENSE KEYS AND VERIFICATION
4.1 License Keys are verified offline by the Software using a public key of
    brillQ; the Software does not transmit data to brillQ.
4.2 Licensee is responsible for keeping License Keys confidential. brillQ may
    revoke and reissue a License Key that has been disclosed.
4.3 brillQ may request, no more than once per year and on reasonable notice, a
    written self-certification of the number of Authorised Users and
    installations.

5. INTELLECTUAL PROPERTY

    right, title and interest in and to the Software, including all
    intellectual property rights, methods and know-how embodied in it.

    its data. brillQ acquires no rights in Licensee's data.
5.3 Feedback voluntarily provided by Licensee may be used by brillQ without
    restriction or compensation.

6. THIRD-PARTY COMPONENTS
The Software depends on open-source components (listed in
THIRD_PARTY_LICENSES.md) that are licensed under their own terms, which govern
those components. Nothing in this Agreement limits Licensee's rights under
those open-source licenses. Third-party components are not part of the
Software for the purposes of Sections 5 and 8.

7.1 Fees are stated in the Order and are payable as specified there. Fees are
    exclusive of VAT and other applicable taxes.
7.2 The license term is stated in the Order (subscription or perpetual with an
    Updates period). Subscription licenses renew as specified in the Order.
7.3 brillQ may terminate this Agreement on written notice if Licensee
    materially breaches it and fails to cure the breach within thirty (30) days
    of notice. Licensee may terminate at any time by ceasing all use of the
    Software; fees already paid are non-refundable except where the law
    requires otherwise.
7.4 Upon termination Licensee shall cease using the Software and destroy all
    copies and License Keys, except that Licensee may retain outputs already
    generated. Sections 3, 5, 8, 9, 10 and 12 survive termination.

8. WARRANTY
8.1 brillQ warrants that, for ninety (90) days from delivery, the Software will
    perform substantially in accordance with its documentation when used as
    specified. Licensee's sole remedy for breach of this warranty is, at
    brillQ's option, correction of the non-conformity or a refund of the fees
    paid for the non-conforming Software.
8.2 EXCEPT AS EXPRESSLY STATED IN THIS SECTION, THE SOFTWARE IS PROVIDED "AS IS"
    AND BRILLQ DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
    WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND
    NON-INFRINGEMENT. STATISTICAL RESULTS DEPEND ON THE QUALITY AND SUITABILITY
    OF LICENSEE'S DATA AND MODEL CHOICES; THE SOFTWARE DOES NOT PROVIDE
    FINANCIAL, REGULATORY OR LEGAL ADVICE, AND LICENSEE REMAINS SOLELY
    RESPONSIBLE FOR DECISIONS TAKEN ON THE BASIS OF ITS OUTPUTS.

9. LIMITATION OF LIABILITY
9.1 TO THE MAXIMUM EXTENT PERMITTED BY LAW, BRILLQ SHALL NOT BE LIABLE FOR ANY
    INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR

    WITH THIS AGREEMENT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
9.2 BRILLQ'S TOTAL AGGREGATE LIABILITY UNDER THIS AGREEMENT SHALL NOT EXCEED
    THE FEES PAID BY LICENSEE FOR THE SOFTWARE IN THE TWELVE (12) MONTHS
    PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

    misconduct (wina umyślna) or any other liability that cannot be excluded
    under applicable law.

party obtained in connection with this Agreement (including the Software's
source code and License Keys, and Licensee's data and results) and use it only
for the purposes of this Agreement, for the term of the Agreement and five (5)
years thereafter.

11. SUPPORT AND UPDATES
Under an active Order brillQ provides e-mail support (hello@brillq.today) on
business days and makes Updates available. Support levels, response times and
professional services (model calibration, integration, training) are specified
in the Order.

     Poland, excluding its conflict-of-law rules and the United Nations
     Convention on Contracts for the International Sale of Goods.

     Agreement. Amendments must be in writing (documentary form suffices).
