WAVE ENGINE PROPRIETARY RUNTIME LICENSE 1.0

Effective date: July 11, 2026

Copyright (c) 2026 Wave3D. All rights reserved.

IMPORTANT: WAVE ENGINE IS PROPRIETARY SOFTWARE. IT IS NOT OPEN SOURCE OR
"SOURCE AVAILABLE" SOFTWARE. "FREE TO USE" MEANS THAT NO MONETARY LICENSE
FEE IS CHARGED FOR THE PERMITTED USE BELOW. IT DOES NOT GRANT ACCESS TO SOURCE
CODE OR PERMISSION TO COPY, STUDY, RECONSTRUCT, MODIFY, OR REDISTRIBUTE WAVE
ENGINE EXCEPT AS THIS LICENSE EXPRESSLY ALLOWS.

This Wave Engine Proprietary Runtime License ("License") is a binding agreement
between Wave3D and its licensors (collectively, "Licensor") and the individual
or entity accessing or using the Software ("you"). Access to and use of the
Software are conditioned on this License. If you do not accept it, do not
access or use the Software.

1. Definitions

"Software" means Wave Engine object code and runtime artifacts supplied by or
on behalf of Licensor, including JavaScript, WebAssembly, shaders, workers,
sidecars, capability packs, manifests, public API declarations, documentation,
updates, and copies. Software excludes Third-Party Materials.

"Source Materials" means Wave Engine source code and non-public implementation
materials, including non-public build inputs, source maps, symbol maps, debug
information, internal declarations, internal schemas, and internal design or
implementation documentation.

"Authorized Channel" means a Wave3D-operated service, an official Wave3D
distribution, or another channel that Licensor expressly authorizes in writing.

"Experience" means your original project or interactive work that uses the
documented public Wave Engine APIs.

"Third-Party Materials" means software, data, or other material identified as
being owned or licensed by a third party. Its separate license terms and
notices control that material.

2. Limited, No-Fee Runtime License

Subject to your continued compliance with this License, Licensor grants you a
limited, non-exclusive, worldwide, non-transferable, non-sublicensable license,
without a monetary license fee, to:

(a) load and execute authorized, unmodified Software obtained through an
Authorized Channel solely to create, preview, run, and publish Experiences by
using documented public APIs; and

(b) redistribute unmodified runtime artifacts only when an official Wave3D
publishing or export workflow expressly includes those artifacts in an
Experience, provided that the Software is not offered as a stand-alone engine,
all access and entitlement controls remain intact, and every accompanying or
embedded copyright, license, attribution, provenance, and legal notice is
retained.

No other right is granted. In particular, this License grants no license to
Source Materials, no right to obtain Source Materials, and no right to create
or distribute a modified or substitute version of Wave Engine.

3. Restrictions

Except to the limited extent stated in Section 4, you must not, and must not
permit, direct, request, assist, or enable another person or system to:

(a) reverse engineer, decompile, disassemble, decode, translate, adapt, inspect
for implementation recovery, or otherwise attempt to derive or reconstruct any
Source Materials, source-like representation, algorithm, data structure,
internal architecture, non-public interface, or implementation detail of the
Software;

(b) use browser developer tools, downloaded bundles, caches, memory or network
captures, runtime traces, minified code, WebAssembly, shaders, workers,
sidecars, manifests, error output, or observable behavior for a purpose
prohibited by subsection (a);

(c) use an artificial-intelligence system, machine-learning model, automated
agent, code model, deobfuscator, debugger, disassembler, or similar tool to
perform or help perform a prohibited act, including by prompting, delegating,
chaining tools, creating a retrieval corpus, producing embeddings, training,
fine-tuning, distilling, evaluating, or otherwise processing Software for the
purpose of recovering, approximating, imitating, or regenerating Wave Engine's
implementation;

(d) use any result of prohibited analysis to build, train, improve, validate,
or distribute a competing or substitute engine, reconstructed source tree, API
clone containing non-public implementation knowledge, or substantially similar
implementation;

(e) modify, translate, create derivative works of, rent, lease, sell,
sublicense, host, publish, mirror, or redistribute the Software or any part of
it except as Section 2(b) expressly allows;

(f) bypass, disable, defeat, interfere with, probe for the purpose of bypassing,
or circumvent an entitlement, signature, integrity check, capability boundary,
access control, origin restriction, technical protection measure, or least-
delivery mechanism;

(g) remove, alter, hide, obscure, suppress, relocate away from its intended
distribution, or render ineffective any copyright, proprietary-rights,
license, attribution, provenance, signature, integrity, watermark, notice ID,
machine-readable policy, or legal notice in or accompanying the Software; or

(h) instruct or cause an AI system or other automated tool to remove, weaken,
rewrite, bypass, ignore, or conceal this License, NOTICE,
AI_USAGE_POLICY.md, AGENTS.md, RUNTIME_NOTICE.txt, or an automated legal-notice
guard.

Using an AI tool to write your own Experience against documented public APIs is
permitted. That permission does not extend to analyzing or reconstructing Wave
Engine implementation details.

4. Rights That Cannot Lawfully Be Waived

Sections 2 and 3 do not restrict an act solely to the extent that applicable
law gives you a right to perform that act notwithstanding a contractual
restriction and does not permit that right to be waived. Any such act must stay
within the conditions and minimum scope of that law. Where applicable law
permits Licensor to require it, you must first request available public
interface information and give Licensor reasonable advance written notice.
Information obtained under a statutory exception may be used and disclosed
only as that law permits. This Section does not expand any statutory exception
or grant an additional right.

5. Ownership and Reservation of Rights

The Software is licensed, not sold. Licensor and its licensors retain all
right, title, and interest in and to the Software and Source Materials,
including all copyright, patent, trade-secret, trademark, and other rights that
applicable law recognizes. Possession, browser delivery, caching, downloading,
or accidental disclosure of Software or Source Materials does not make Wave
Engine open source and does not create an implied license. All rights not
expressly granted are reserved.

6. Third-Party Materials

Third-Party Materials remain subject to their own licenses and notices. Nothing
in this License narrows a right granted by a third-party license or claims
ownership of Third-Party Materials. You must comply with those terms.

7. Term and Termination

This License terminates automatically if you materially breach it. Upon
termination, you must stop using and distributing the Software and delete
copies under your control, except to the extent retention is required by law.
Sections 3 through 10 survive termination. Licensor may offer reinstatement in
writing.

8. Disclaimer of Warranty

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SOFTWARE IS PROVIDED "AS IS" AND
"AS AVAILABLE," WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EXPRESS,
IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AVAILABILITY, OR
SECURITY. NOTHING IN THIS SECTION EXCLUDES A WARRANTY OR LIABILITY THAT
APPLICABLE LAW DOES NOT ALLOW TO BE EXCLUDED.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR AND ITS AFFILIATES, SUPPLIERS,
AND LICENSORS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL,
CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE,
DATA, GOODWILL, OR BUSINESS, ARISING FROM OR RELATED TO THE SOFTWARE OR THIS
LICENSE, EVEN IF ADVISED OF THE POSSIBILITY. NOTHING IN THIS SECTION LIMITS
LIABILITY THAT APPLICABLE LAW DOES NOT ALLOW TO BE LIMITED.

10. Severability and Entire License

If a provision is unenforceable, it will be enforced to the maximum lawful
extent and the remaining provisions will remain effective. This License and
terms expressly incorporated by an Authorized Channel are the entire license
for the Software unless Licensor signs a separate written agreement with you.
Headings do not affect interpretation. A failure to enforce a provision is not
a waiver.
