Licensor:             INTERCHAINED LLC

Licensed Work:        NEDB, version 4.0.0 and later.
                      The Licensed Work is (c) 2026 INTERCHAINED LLC.

Additional Use Grant: You may make production use of the Licensed Work,
                      without limitation and without obtaining any further
                      permission or license from the Licensor, provided that
                      your Annual Revenue is less than one million United
                      States dollars (USD $1,000,000).

                      "Annual Revenue" means the total gross revenue,
                      recognised under the accounting standards you ordinarily
                      apply, of you together with all of your Affiliates, over
                      your most recently completed fiscal year. "Affiliates"
                      means any entity that controls, is controlled by, or is
                      under common control with you, where "control" means
                      direct or indirect ownership of more than fifty percent
                      (50%) of the voting interests of an entity.

                      Annual Revenue is measured on your organisation as a
                      whole. It is NOT limited to revenue derived from, or
                      attributable to, the Licensed Work. An organisation
                      whose Annual Revenue is USD $1,000,000 or more must
                      obtain an additional use grant from the Licensor before
                      making production use of the Licensed Work.

                      Regardless of Annual Revenue, this Additional Use Grant
                      does not permit you to offer the Licensed Work, or a
                      substantially similar derivative of it, to third parties
                      as a managed, hosted or database-as-a-service offering.
                      That use requires a separate commercial license.

                      Non-production use is always permitted: development,
                      testing, continuous integration, evaluation, research,
                      teaching and personal projects are unrestricted for
                      everyone, at any revenue.

                      To obtain an additional use grant, contact
                      licensing@interchained.org.

Change Date:          2030-09-11

Change License:       Apache License, Version 2.0
                      The full text ships in this repository as
                      COPYING-APACHE-2.0.txt, so the grant is verifiable from
                      the source tree alone.

                      The Change License relicenses the Licensed Work's OWN
                      source. It does not relicense third-party dependencies,
                      which keep their own terms — inventoried in
                      THIRD_PARTY.md.
