PROPRIETARY LICENSE — OPENDOOR PARTNER SDK (DISTRIBUTED ARTIFACTS ONLY)

Copyright © 2026 Opendoor Labs. All rights reserved.

1. Scope

This license applies solely to the bundled, compiled, or otherwise distributable
artifacts made available by Opendoor Labs on public package registries as part
of the "Opendoor Partner SDK" (the "Artifacts"). "Artifacts" include, without
limitation:

- The Ruby gem "opendoor-partner-sdk-server-ruby" distributed via RubyGems.org;
  and
- The JavaScript/TypeScript npm packages published under the @opendoor/ scope
  that are built from this repository (including, for example,
  @opendoor/partner-sdk-server-js-core, @opendoor/partner-sdk-client-js-core,
  @opendoor/partner-sdk-client-react, and @opendoor/partner-sdk-client-vue).

For clarity, this license does not grant any rights to any source code, build
scripts, or other materials that are not included in the Artifacts. All such
materials remain proprietary and confidential to Opendoor Labs.

2. Prerequisite; Partner Agreement Controls

No license is granted under this notice unless you (or the entity on whose
behalf you act) have an active, fully executed written partner agreement with
Opendoor Labs Inc. ("Opendoor") governing your use of Opendoor's partner APIs
(the "Partner Agreement") and you are in compliance with the Partner Agreement.
Use of the Artifacts without an active Partner Agreement is not authorized.

If there is a conflict between this license and the Partner Agreement, the
Partner Agreement will control.

3. Limited License Grant

Subject to Section 2, Opendoor grants you a limited, non-exclusive,
non-transferable, non-sublicensable, revocable license to: (a) download,
install, copy, and use the Artifacts for internal development, testing, and
operation; and (b) use the Artifacts solely to integrate your applications with
Opendoor partner APIs in accordance with Opendoor's published documentation and
the Partner Agreement.

You may reproduce the Artifacts as reasonably necessary for backup, caching,
CI/CD, and deployment, and you may distribute the Artifacts only as embedded or
included with your application for the authorized purpose above, and not on a
standalone basis.

4. Restrictions

Except as expressly permitted in Section 3 or the Partner Agreement, you may
not (and may not permit any third party to): (a) copy, modify, translate, or
create derivative works of the Artifacts; (b) distribute, sublicense, sell,
lease, or otherwise make the Artifacts available to any third party on a
standalone basis; (c) reverse engineer, decompile, or disassemble the
Artifacts, except to the extent such restriction is prohibited by applicable
law; (d) remove, obscure, or alter any proprietary notices in the Artifacts; or
(e) use the Artifacts for any purpose other than the authorized integration with
Opendoor partner APIs. No rights are granted to Opendoor Labs' trademarks,
service marks, or logos under this license.

5. Ownership

The Artifacts are licensed, not sold. Opendoor retains all right, title, and
interest in and to the Artifacts, including all intellectual property rights
therein.

7. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL OPENDOOR BE LIABLE FOR
ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY
DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, OR BUSINESS INTERRUPTION,
ARISING OUT OF OR RELATED TO THE ARTIFACTS OR THIS LICENSE, EVEN IF ADVISED OF
THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OPENDOOR'S TOTAL LIABILITY ARISING OUT
OF OR RELATED TO THE ARTIFACTS OR THIS LICENSE WILL NOT EXCEED THE LESSER OF
$100 OR THE AMOUNTS PAID BY YOU TO OPENDOOR UNDER THE PARTNER AGREEMENT IN THE
TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

8. Termination

This license will terminate automatically upon: (a) any breach of this license;
(b) expiration or termination of the Partner Agreement; or (c) Opendoor's
written notice. Upon termination, you must immediately cease all use of the
Artifacts and destroy all copies in your possession or control, except that you
may retain copies solely as required to comply with applicable law or bona fide
internal record retention policies.

9. Export and Sanctions Compliance

You represent and warrant that you are not (and are not acting on behalf of)
any person or entity that is the subject or target of sanctions administered or
enforced by the United States (including the U.S. Department of the Treasury's
Office of Foreign Assets Control), and that you will not use, export,
re-export, transfer, or release the Artifacts in violation of applicable export
