SOURCE-AVAILABLE LICENSE. NOT AN OSI-APPROVED OPEN-SOURCE
LICENSE.

Copyright © 2026 Eagle AI Corp. All rights reserved except as expressly granted in this License.

This Eagle 4 Source-Available License, the “License,” governs use of the Software and
incorporates the Eagle Trademark Policy. By downloading, cloning, forking, copying,

Software, Licensee accepts and agrees to this License and the incorporated Eagle
Trademark Policy. If Licensee does not agree, Licensee may possess or inspect the public
repository only to the extent permitted by law and may not exercise any licensed right.

Acceptance and Repository Access.

By downloading, cloning, forking, copying, accessing, modifying, using, hosting, distributing, or
otherwise exercising any right in the Software, a user accepts and agrees to this License and the
incorporated Eagle Trademark Policy. If the user acts for an entity, the user represents that the
user has authority to bind that entity. A user who does not agree may possess or inspect the
public repository only to the extent permitted by law but may not exercise any licensed right.

The LICENSE file, repository README, repository notice, source-file notices, and NOTICE
file provide conspicuous notice that this License and the incorporated Eagle Trademark Policy
apply to the Software. No click-through, gated download, checkbox, or repository assent record
is required for acceptance by conduct under this section.

A copy obtained from a permitted downstream distribution is subject to this License as provided
in Section 4. Any downstream recipient accepts and agrees to this License and the incorporated
Eagle Trademark Policy by downloading, cloning, forking, copying, accessing, modifying, using,
hosting, distributing, or otherwise exercising any licensed right. A recipient who does not agree
may possess or inspect the copy only to the extent permitted by law and may not exercise any
licensed right.

1.  Definitions.

    a. “Affiliate” means an entity that directly or indirectly Controls, is Controlled by, or is
    under common Control with a party. “Control” means ownership of more than 50 percent
    of the voting interests of an entity or the power to direct its management and policies.

    b. “Aggregate Revenue” means the total gross revenue of Licensee and all Affiliates from
    all sources, determined on a consolidated basis over the applicable consecutive 12-month
    period under consistently applied generally accepted accounting principles or International
    Financial Reporting Standards, with intercompany revenue eliminated and without
    duplication.

    c. “Commercial Use” means using the Software, a Modification, or their functionality for
    direct or indirect commercial advantage or revenue generation, including in or for any
    paid product or service, customer-facing production use, software as a service,
    application programming interface, hosting, consulting, integration, original-equipment-
    manufacturer or embedded use, advertising-supported service, commercialization of a
    fork or derivative work, or use that materially supports a revenue-generating product or
    service.

         Commercial Use does not include genuine internal evaluation, academic research,
         nonprofit research, education, personal noncommercial use, or internal noncommercial
         experimentation, in each case only where the use is not customer-facing, does not
         generate revenue or commercial advantage, and does not materially support a revenue-
         generating product or service.

    d. “Competing Offering” means a product or service whose principal functionality
    substantially substitutes for the principal functionality of Eagle 4, or that incorporates
    material Eagle 4 technology into a model, inference, training, acceleration, or serving
    framework that competes with Eagle 4. A separate commercial license is required for
    every Competing Offering.

         A Competing Offering does not include a product or service merely because it
         interoperates with Eagle 4, calls or is called by Eagle 4 through documented interfaces,
         complements Eagle 4, uses outputs generated by Eagle 4, or includes only incidental or
         immaterial use of Eagle 4 that does not provide a material portion of the product’s or
         service’s principal functionality.

    e. “Eagle 4” means the Software and the technology embodied in it, including EAGLE-
    Harness and EAGLE Efficient LM Head technology, but excluding independently
    developed technology that merely interoperates with the Software.

    f. “Eagle Files” means files or other materials that contain, reproduce, modify, implement,
    port, or are derived from any portion of the Software. A file is governed by Apache
    License, Version 2.0, “Apache-2.0,” only if its copyright owner expressly designates that
    file as Apache-2.0.

    g. “Licensor” means Eagle AI Corp.

    h. “Licensee” means the individual or entity exercising rights under this License.

    i. “Modification” means any change to the Software or derivative work based on the
    Software. “Distribute” means to provide a copy of the Software or a Modification to a
    third party, excluding remote access to functionality without transfer of a copy.

    j. “Software” means the Eagle 4 materials made available with this License, including
    applicable model architecture, model weights and parameters, source code, object code,
    configuration files, inference and training code, documentation, and any portion or
    Modification of them.

2.  License Grant.

    a. Subject to this License, Licensor grants Licensee a worldwide, royalty-free,
    nonexclusive, nontransferable except under Section 11, and nonsublicensable license,
    except as expressly permitted below, under Licensor’s copyright and similar rights to
    access, use, reproduce, run, evaluate, study, analyze, benchmark, teach with, modify,
    create derivative works of, and Distribute the Software for research, evaluation,
    education, personal use, internal noncommercial experimentation, academic research,
    nonprofit research, and other noncommercial purposes and, subject to Sections 3 and 4,
    Commercial Use.

    b. Subject to Sections 3 and 4, Licensee may use, reproduce, modify, and Distribute the
    Software and Modifications for the noncommercial purposes expressly permitted above
    and for Commercial Use only to the extent permitted by Section 3, and may permit
    contractors and service providers to do so solely on Licensee’s behalf if their activities
    comply with this License, are not a Competing Offering, and Licensee remains
    responsible for their compliance. Any Commercial Use not permitted by Section 3
    requires a separate written commercial license with Eagle AI Corp before it begins.
    Nothing in this License requires Eagle AI Corp to offer a commercial license or agree to
    any particular fees or terms.

    c. No right is granted by implication, estoppel, or otherwise. Rights not expressly granted
    are reserved. A separate written commercial license may grant additional rights.
    Commercial-license inquiries may be sent to licensing@eagle.ai.

3.  Commercial and Competitive Restrictions.

    a. Licensee may not develop, offer, sell, license, host, provide, or otherwise commercialize
    a Competing Offering under this License. Any such activity requires a separate written
    commercial license from Licensor before the activity begins, regardless of Aggregate
    Revenue.

    b. Licensee may not evade the Competing Offering restriction by copying, forking,
    renaming, rebranding, translating, wrapping, rewriting, porting, or making superficial
    changes to Eagle 4, or by placing material Eagle 4 technology in another framework.
    The substance and principal functionality of the offering control, not its name,
    packaging, interface, or stated purpose.

    c. Commercial Use that is not a Competing Offering is permitted under this License only
    while Aggregate Revenue from all sources of the Licensee and all Affiliates has not
    exceeded 20 million US dollars (or the equivalent in other currencies) in total over any
    consecutive 12 months, and only to the extent otherwise permitted by this License. If
    Aggregate Revenue exceeds that threshold, Licensee must enter into a separate agreement
    with Eagle AI Corp before Licensee or any Affiliate uses the Software or any derivative
    work of the Software, including a Modification, for any Commercial Use. This
    requirement applies prospectively beginning on the date the threshold is first exceeded
    and, once triggered, continues thereafter notwithstanding any later decrease in Aggregate
    Revenue. It does not retroactively prohibit Commercial Use occurring before that date.

    d. Upon exceeding the Aggregate Revenue threshold in this Section, Licensee must cease
    any Commercial Use unless the required separate agreement is already in effect, and must
    contact Eagle AI Corp at licensing@eagle.ai before beginning or continuing that use. No
    negotiation period, grace period, or temporary commercial-use permission applies after
    the threshold is exceeded.
    e. Licensor has no obligation to offer a commercial license or agree to any particular fees or
    terms. Unless and until a separate written commercial license is executed when required
    under this Section, Licensee may exercise only the rights otherwise permitted by this
    License and may not begin or continue the Commercial Use or Competing Offering for
    which the separate license is required.

    f. Licensee must not divide activities or revenue among Affiliates, customers, contractors,
    resellers, or other persons, or otherwise structure activities or transactions for the purpose
    of avoiding this Section. Licensee and all Affiliates are treated as one licensee for
    purposes of Aggregate Revenue and the Commercial Use, Competing Offering, and
    compliance restrictions.

4.  Distribution, Source, and Attribution Conditions.

    a. Every permitted distribution of the Software or a Modification must include this License
    in a file named LICENSE, the NOTICE file, and all applicable source-file notices, and
    must preserve all copyright, patent, license, NOTICE, attribution, and other proprietary
    notices supplied with the Software. Each such distribution must include a conspicuous
    statement that the Software is subject to this source-available License, which is not an
    OSI-approved open-source license, and reasonable directions for locating the Eagle
    Trademark Policy. Each distribution must also state conspicuously that downloading,
    cloning, forking, copying, accessing, modifying, using, hosting, distributing, or
    otherwise exercising any licensed right constitutes acceptance of this License and the
    incorporated Eagle Trademark Policy. Licensee must reproduce required notices in the
    corresponding files or in a customary third-party notices location.

    b. Licensee must identify each materially modified file and include a prominent
    modification notice stating that the file was modified, the date of the material
    modification, and the modifying person or entity. A consolidated change log is permitted
    if it clearly maps each material modification to the affected files.

    c. If Licensee Distributes a Modification in source or executable form, Licensee must make
    the complete corresponding source form of that Modification available to each recipient,
    at no additional license fee, under this License. The source must include the modified
    source code, configuration, scripts, adapters, patches, or weight deltas reasonably
    necessary to use and reproduce the distributed Modification, but need not include
    separable proprietary components that are not derived from or modifications of the
    Software.

    d. Every permitted use beyond private possession or inspection must provide clear
    attribution to Eagle AI Corp and Eagle 4 in documentation, repository materials, or a
    customary third-party notices location. Attribution requires preservation of all copyright
    notices, the LICENSE file, the NOTICE file, applicable source-file notices, and required
    modification notices. Every public repository, publication, demonstration, distributed
    software release, or public description of a derivative work must include a reasonably
    prominent statement substantially similar to: “This project includes or is derived from
    Eagle 4 technology developed by Eagle AI Corp. It is not an official Eagle AI Corp
    project unless expressly stated otherwise.” No user-interface badge, splash screen,
    persistent display, or other badgeware is required for purely noncommercial use, but a
    separate commercial agreement may establish negotiated attribution terms.

    e. Licensee may not remove, conceal, obscure, materially alter, or materially reduce
    required attribution; falsely claim original authorship of Eagle 4 or Licensor’s work;
    misleadingly rename or rebrand the Software or a Modification; or state or imply that a
    fork, Modification, project, product, service, or distribution is official or is an official
    Eagle 4 release unless Licensor has authorized that statement in writing.

    f. Forks and derivative works may be made and Distributed under the rights otherwise
    granted by this License if they remain subject to this License and preserve the required
    attribution. A Distributed fork or Modification must use a distinguishable primary
    name, preserve the Eagle LICENSE and NOTICE files and applicable source-file and
    modification notices, identify Eagle AI Corp and Eagle 4 as the origin, and avoid
    suggesting official status, affiliation, certification, sponsorship, or endorsement. This
    License does not prohibit a truthful new name that complies with Section 5; it
    prohibits removal of attribution, false claims of original authorship, and confusing use
    of Eagle marks.

    g. Renaming, rebranding, translating, wrapping, porting, integrating, modifying, or
    moving any Eagle File or Eagle 4 code into another file, directory, repository,
    framework, package, or distribution does not remove or reduce this License’s
    attribution, Commercial Use, source, trademark, notice, modification, or other
    obligations. The substance and origin of the code control, not its name, location,
    packaging, interface, or surrounding repository license.

    h. Eagle AI Corp may separately designate a minimal administrative, registration, or
    loader file as Apache-2.0 by an express file-level notice. Any such designation applies
    only to the identified file and does not relicense any Eagle File. Recommended
    compliance language appears in Exhibits A and E.

5.  Trademarks and Names.

    a. Licensor reserves all rights in EAGLE, Eagle 4, EAGLE-Harness, EAGLE Efficient LM
    Head, all associated logos, and all related names, marks, trade dress, and goodwill.
    Except for the limited permission below, this License grants no trademark or branding
    rights.

    b. The Eagle Trademark Policy is incorporated by reference solely with respect to use of
    Eagle names, marks, logos, and branding. Acceptance of this License includes agreement
    to comply with that policy. The policy does not expand the copyright, patent, or other
    Software restrictions in this License.

    c. Licensee may make truthful, nonmisleading nominative references to Eagle 4 solely to
    identify compatibility, origin, or the Software used, provided the reference is no more
    prominent than reasonably necessary and complies with the Eagle Trademark Policy.

    d. A Modification or fork that is Distributed or offered to third parties must use a
    distinguishable primary name and must not use “Eagle,” “Eagle 4,” or a confusingly
    similar term as its primary product, service, project, or company name without Licensor’s
    prior written consent.

    e. Licensee must not state or imply affiliation with, certification by, sponsorship by, or
    endorsement from Licensor, or use any mark or logo in a manner likely to cause
    confusion as to source, sponsorship, or official status. The form in Exhibit D may be used
    to clarify non-affiliation.

6.  Limited Patent License and Retaliation.

    a. Subject to this License, Licensor grants Licensee a worldwide, royalty-free,
    nonexclusive, nontransferable except under Section 11 patent license, without the right to
    sublicense except to contractors acting solely for Licensee, to make, have made, use,
    offer to sell, sell, import, and otherwise transfer the Software solely to the extent
    necessary for a use expressly permitted by this License and only under patent claims
    Licensor can license that are necessarily infringed by the unmodified Software or by their
    combination with Licensor-provided components.

    b. If Licensee or an Affiliate initiates or maintains a patent claim alleging that the Software
    or a compliant use of it infringes a patent, the patent license in this Section terminates
    upon filing of that claim. This retaliation provision does not apply to a compulsory
    counterclaim or defensive response that Licensee withdraws within 30 days after it may
    lawfully do so.

7.  Ownership.

    a. As between the parties, Licensor and its licensors own all right, title, and interest in and
    to the Software, Eagle 4 technology, Licensor-provided materials, and all intellectual
    property rights in them. No title transfers to Licensee.

    b. As between the parties, Licensee owns its original contributions to a Modification,
    subject to Licensor’s ownership of the Software and the conditions and licenses in this
    License. No Modification limits Licensor’s right to develop, license, or use similar or
    competing technology, provided Licensor does not use Licensee’s confidential
    information.

8.  Records and Limited Audit.

    a. For three years after each use or distribution of the Software or a Modification,
    Licensee must keep reasonably complete records sufficient to verify Aggregate
    Revenue and compliance with the Commercial Use and Competing Offering
    restrictions and Section 4, including records reasonably necessary to investigate
    whether the Aggregate Revenue threshold has been exceeded, unauthorized
    Commercial Use, unauthorized relicensing, or failure to identify and preserve the
    licensing and notices applicable to Eagle Files. Licensee need not disclose unrelated
    product data, personal data, source code unrelated to the Software, or legally
    privileged material.

    b. If Licensor has a reasonable, documented basis to suspect Commercial Use or another
    material violation of Sections 3 or 4, Licensor may, no more than once in any 12-month
    period and on at least 30 days’ written notice, have an independent auditor bound by
    written confidentiality obligations inspect the relevant records during normal business
    hours solely to verify compliance with Sections 3, 4, and 8. The audit must minimize
    disruption, and the auditor may report only compliance findings reasonably necessary for
    enforcement. Licensor bears the cost unless the audit finds a material breach, in which
    case Licensee must reimburse reasonable audit costs. The frequency and notice limits do
    not apply where Licensor has a reasonable, documented basis to suspect fraud or
    intentional circumvention.

9.  Term and Termination.

    a. This License begins when Licensee accepts it by conduct as described in the
    Acceptance and Repository Access section and continues until terminated. A material
    breach automatically terminates this License if the breach is curable and Licensee fails
    to cure it within 30 days after written notice describing the breach in reasonable detail.
    A noncurable breach, fraud, willful circumvention of Section 3, unauthorized
    Commercial Use, or a knowingly false claim of official status may be terminated
    immediately by written notice.

    b. Upon termination, Licensee must stop exercising rights under this License and stop
    distributing the Software, and within 30 days delete or destroy copies under its control
    except one archival copy kept solely for legal compliance. Termination does not affect
    compliant licenses previously granted to recipients, but Licensee remains liable for pre-
    termination breaches. The Acceptance and Repository Access section and Sections 1, 5, 7,
    8, 9, 10, 11, and 12 survive termination.

10. Enforcement; Disclaimer; Limitation of Liability.

a. Licensee acknowledges that unauthorized Commercial Use, competitive use,
relicensing, disclosure, distribution, or misuse of Licensor’s intellectual property, or
failure to preserve the licensing, attribution, source, trademark, modification, and notice
obligations applicable to Eagle Files, may cause irreparable harm for which damages are
inadequate. Licensor may seek injunctive or equitable relief, in addition to all other
cumulative remedies, without posting bond to the extent permitted by law. Delay or
failure to enforce is not a waiver. In an action to enforce this License, the prevailing
party is entitled to reasonable attorneys’ fees and costs to the extent permitted by law.

b. THE SOFTWARE, DOCUMENTATION, OUTPUTS, AND RESULTS ARE
PROVIDED “AS IS” AND “AS AVAILABLE,” WITH ALL FAULTS. TO THE
MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR AND ITS AFFILIATES,
LICENSORS, AND CONTRIBUTORS DISCLAIM ALL EXPRESS, IMPLIED,
STATUTORY, AND OTHER WARRANTIES, INCLUDING MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT,
ACCURACY, SECURITY, AND WARRANTIES ARISING FROM COURSE OF
DEALING OR USAGE OF TRADE. LICENSEE IS SOLELY RESPONSIBLE FOR
EVALUATING FITNESS, SAFETY, SECURITY, AND LEGAL COMPLIANCE. TO
THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR AND ITS
AFFILIATES, LICENSORS, AND CONTRIBUTORS WILL NOT BE LIABLE FOR
ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR
CONSEQUENTIAL DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA,
GOODWILL, OR BUSINESS INTERRUPTION, ARISING FROM OR RELATED TO
THE SOFTWARE OR THIS LICENSE, EVEN IF ADVISED OF THE POSSIBILITY.
THEIR AGGREGATE LIABILITY WILL NOT EXCEED THE GREATER OF US $100
OR THE AMOUNT LICENSEE PAID LICENSOR FOR THE SOFTWARE DURING
THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO LIABILITY. THESE
LIMITS APPLY REGARDLESS OF THEORY AND TO THE EXTENT PERMITTED
BY LAW.

11. General.

a. Licensee must comply with applicable laws, including export-control, sanctions, privacy,
and safety laws. Licensee may not assign this License without Licensor’s prior written
consent, except with written notice in connection with a merger, reorganization, or sale of
substantially all assets relating to the Software if the assignee agrees in writing to be
bound and is not a Competing Offering provider; any other attempted assignment is void.
Licensor may assign this License and its rights. If any provision is unenforceable, it will
be modified to the minimum extent necessary and the remainder will remain effective.
This License is governed by the laws of the state of New York, excluding conflict-of-laws
rules, and the parties consent to exclusive jurisdiction and venue in the state and federal
courts located in New York County, New York.

b. This License is the entire agreement concerning its subject matter and may be amended
or waived only in a writing signed by Licensor. Headings are for convenience, and
“including” means “including without limitation.”

c. Notices and Commercial Licensing. Legal notices to Licensor and commercial-license
inquiries must be sent to licensing@eagle.ai. A Licensee must contact Eagle AI Corp and
enter into a separate written commercial agreement before beginning or continuing any
Commercial Use for which Section 3 requires that agreement. Notices to Licensee may
be sent to the contact information Licensee provides to Licensor or, if none, to a publicly
listed legal contact. Email notice is effective when sent, absent a delivery-failure
message.
