MassTransit Commercial Software License Agreement

Last Updated: May 4, 2026

Massient, Inc.
A Delaware corporation
8 The Green, Suite B, Dover, DE 19901, USA
(“Licensor”)

1. License Grant

Subject to the terms of this Agreement and payment of applicable fees, Licensor grants Licensee a non-exclusive, non-transferable, non-sublicensable license to use MassTransit (the “Software”) during the subscription term.

Licensor offers two commercial license scopes:

(a) Single-Product Line License.

A Single-Product Line license permits use of the Software within a single product line. A product line is defined as a cohesive product or system, consisting of one or more related services or applications that are developed, versioned, and delivered together as a single offering. Multiple deployments of the same product line, including customer-specific, on-premises, or isolated installations, are covered by a Single-Product Line license.

(b) Organization-Wide (Multi-Line) License.

An Organization-Wide license permits use of the Software across all product lines, systems, and internal applications operated by the Licensee and its Affiliates.

For purposes of this Agreement, “Affiliate” means any entity directly or indirectly controlling, controlled by, or under common control with the Licensee, where control means more than fifty percent (50%) ownership of the voting interests.

The applicable license scope is determined by the subscription purchased by the Licensee and reflected on the corresponding order, invoice, or subscription record. The license is either product-scoped or organization-scoped and is not based on message volume, endpoints, deployments, or number of services.

2. Contractors and Customer Projects

If contractors or agencies build and deploy applications incorporating the Software for their client under their own license, that use is permitted so long as the contractor maintains the software for the client. If the client assumes ownership or maintenance of the application, the client must purchase their own license appropriate for their organization.

3. Legacy Versions

MassTransit v8 and earlier remain free and open source under their original licenses. However, they are unsupported under this Agreement. This Agreement applies only to MassTransit v9 and later.

4. Subscription License with Perpetual Downgrade Rights

Subscription Term: Licensee’s rights to new versions of the Software are granted under an active subscription. As long as Licensee maintains a valid subscription, Licensee may upgrade to and use the most current version.
Perpetual Rights for Licensed Version: If Licensee’s subscription expires or is not renewed, Licensee retains a perpetual license to use the most recent version of the Software that was available during the subscription term (“Last Licensed Version”). This perpetual right is not affected by later changes to this Agreement.
Redeployment: Redeployment of applications using the same Software version does not require a new license file. A current subscription is only required when upgrading to newer versions.
Upgrades: Only Licensees with an active subscription may upgrade to new versions beyond the Last Licensed Version.

5. Restrictions

Licensee may not:

Redistribute the Software except as embedded in Licensee’s applications, consistent with Section 2.
Reverse-engineer or create derivative works of the Software except as permitted by law.

6. Support & Maintenance

Support and maintenance services, if included with the subscription, are provided in accordance with Licensor’s then-current support terms published at the Licensor website.

7. Intellectual Property

Licensor retains all rights, titles, and interest in and to the Software, including all related intellectual property rights.

8. Protections & Compliance

Confidentiality: Licensee shall treat any source code, license keys, support materials, and related non-public information as confidential and shall not disclose them to third parties, except as necessary to exercise rights under this Agreement.
Audit Rights: Licensor may, no more than once per calendar year, submit a written request to Licensee for records reasonably necessary to demonstrate Licensee’s compliance with this Agreement, including records relating to the number of product lines deploying the Software and the applicable license scope. Licensee shall provide such records within thirty (30) days of receipt of the written request. Licensor shall treat all records provided by Licensee as confidential and shall use them solely for confirming compliance. Each party will bear its own costs associated with any audit, unless a material breach is discovered, in which case Licensee will reimburse reasonable audit costs.
Export Controls & Sanctions: Licensee agrees to comply with all applicable U.S. and international export laws and regulations and shall not transfer the Software to restricted jurisdictions or prohibited parties.
Government Use: If Licensee is a U.S. government agency or contractor, the Software is provided as “commercial computer software” and use is subject to restrictions in FAR 12.212 or DFARS 227.7202.
Assignment & Change of Control: Licensee may not assign, sublicense, or otherwise transfer this Agreement, by operation of law or otherwise, without Licensor’s prior written consent, which shall not be unreasonably withheld, except in the case of a merger or acquisition where the successor agrees to be bound by this Agreement.

9. Warranty Disclaimer, and Exclusive Remedies

The Software is provided “as is” without a warranty of any kind, express or implied.
Licensee must notify Licensor of any service deficiencies within thirty (30) days from performance of the defective services. LICENSOR DOES NOT GUARANTEE THAT THE SOFTWARE WILL PERFORM ERROR-FREE OR UNINTERRUPTED, OR THAT LICENSOR WILL CORRECT ALL SOFTWARE ERRORS.
FOR ANY BREACH OF THE ABOVE WARRANTIES, LICENSEE’S EXCLUSIVE REMEDY AND LICENSOR’S ENTIRE LIABILITY SHALL BE: (A) THE CORRECTION OF SOFTWARE ERRORS THAT CAUSE BREACH OF THE WARRANTY; OR, IF LICENSOR CANNOT SUBSTANTIALLY CORRECT SUCH BREACH IN A COMMERCIALLY REASONABLE MANNER, LICENSEE MAY END THE SUBSCRIPTION TERM AND RECOVER A PRORATED PORTION OF ANY LICENSE FEES PREPAID TO LICENSOR; OR (B) THE REPERFORMANCE OF THE DEFICIENT SUPPORT SERVICES. TO THE EXTENT PERMITTED BY LAW, THESE WARRANTIES ARE EXCLUSIVE AND THERE ARE NO OTHER EXPRESS OR IMPLIED WARRANTIES OR CONDITIONS INCLUDING WARRANTIES OR CONDITIONS OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

10. Indemnification & Limitation of Liability

Indemnification by Licensor: Licensor shall defend and indemnify Licensee, its parents, subsidiaries, Affiliates, and each of their respective officers, employees, contractors, and agents from and against third-party claims alleging that the Software infringes a U.S. copyright or patent, provided Licensee promptly notifies Licensor and cooperates in the defense.
Exclusions: Licensor shall have no obligation to indemnify for claims arising from modifications made by Licensee or use in combination with non-Licensor products.
Liability Cap: Licensor’s total liability under this Agreement shall not exceed the fees paid by Licensee in the twelve (12) months preceding the claim.
No Consequential Damages: Licensor shall not be liable for indirect, incidental, or consequential damages.

11. Termination

Either party may terminate this Agreement if the other party materially breaches it and fails to cure within thirty (30) days of notice. Upon termination, Licensee must cease using versions of the Software released after the Last Licensed Version, but may continue to use the Last Licensed Version perpetually under Section 4.

12. Miscellaneous Provisions

Language. This Agreement has been agreed to only in the English language. This English language version will control regardless of whether any translations of this Agreement have been prepared or exchanged.

All communications in connection with this Agreement will be in the English language.
Notices. Any notices to Licensor under this Agreement must be in writing and sent by email to support@massient.com. Notices to Licensee will be sent to the customer primary contact email address. Notices will be considered to have been given at the time of email receipt.
Choice of law; Jurisdiction; Jury Waiver. This agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware without regard to its choice of law, and all applicable laws, regulations, treaties, or ordinances of the U.S. This agreement shall be interpreted in accordance with the commonly understood meaning of the words and phrases in the U.S. All judicial proceedings regarding any dispute and/ or controversy relating to Maintenance shall be initiated in the State or Federal courts sitting in Delaware, and each party irrevocably submits to the jurisdiction and venue of any such court in any such proceeding. BOTH PARTIES WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT.

Severability. If any of the parties’ obligations under this agreement are found by a court of competent jurisdiction to be illegal or unenforceable in any respect, such illegality or unenforceability will be interpreted to achieve the goals of such provision to the greatest extent possible under applicable law but shall not affect the other provisions of this agreement, all of which shall remain enforceable in accordance with their terms.
No waiver. The parties shall not be deemed to waive any of their rights or remedies under this agreement unless such a waiver is in writing and signed by the party to be bound. No delay or omission on the part of either party in exercising any right or remedy under this agreement will be construed to be a waiver thereof. A waiver of any right or remedy on any one occasion shall not be construed as a bar to or waiver of such right or remedy or any other right or remedy on any future occasion.
Data Protection. Licensee acknowledges that correspondence and log files generated in conjunction with a request for Support Services may contain sensitive, confidential, or personal information. Licensee is solely responsible for taking the steps it considers necessary to protect the data, including obfuscating the logs or otherwise guarding the information before sending it to Licensor. Licensor shall not retain, use, or disclose such personal information for any purpose other than as necessary to perform the Support Services, nor disclose such personal information outside the Parties’ direct business relationship.
Force Majeure. In no event shall a party be liable to the other party for any delay or failure to perform its obligations under this agreement (other than a failure to pay amounts owed), which delay or failure to perform is attributable to an event of force majeure or other causes beyond the control of such a party and without the fault or negligence of the party claiming excusable delay.

Unless the context of this Agreement clearly requires otherwise: (a) references to the plural include the singular and the singular the plural; (b) “or” has the inclusive meaning frequently identified with the phrase “and/or”; and (c) “including” has the inclusive meaning frequently identified with the phrase “including but not limited to” or “including without limitation.” Any reference in this Agreement to any statute, rule, regulation, or agreement, including this Agreement, will be deemed to include such a statute, rule, regulation, or agreement as it may be modified, varied, amended, or supplemented from time to time.

Any terms or conditions contained in a purchase order, vendor onboarding portal, or other ordering documents that conflict with or are additional to this Agreement are void and of no effect, and the Software is provided solely under the terms of this Agreement.

The applicable license scope is determined by the subscription purchased by the Licensee and reflected on the corresponding order, invoice, or subscription record.
The license is either product-scoped or organization-scoped and is not based on message volume, endpoints, deployments, or number of services.

## 2. Contractors and Customer Projects
If contractors or agencies build and deploy applications incorporating the Software for their client under their own license, that use is permitted so long as the contractor maintains the software for the client. If the client assumes ownership or maintenance of the application, the client must purchase their own license appropriate for their organization.

## 3. Legacy Versions
MassTransit v8 and earlier remain free and open source under their original licenses. However, they are unsupported under this Agreement. This Agreement applies only to MassTransit v9 and later.

## 4. Subscription License with Perpetual Downgrade Rights
1. **Subscription Term**: Licensee’s rights to new versions of the Software are granted under an active subscription. As long as Licensee maintains a valid subscription, Licensee may upgrade to and use the most current version.
2. **Perpetual Rights for Licensed Version**: If Licensee’s subscription expires or is not renewed, Licensee retains a perpetual license to use the most recent version of the Software that was available during the subscription term (“Last Licensed Version”). This perpetual right is not affected by later changes to this Agreement.
3. **Redeployment**: Redeployment of applications using the same Software version does not require a new license file. A current subscription is only required when upgrading to newer versions.
4. **Upgrades**: Only Licensees with an active subscription may upgrade to new versions beyond the Last Licensed Version.

## 5. Restrictions
Licensee may not:
- Redistribute the Software except as embedded in Licensee’s applications, consistent with Section 2.
- Reverse-engineer or create derivative works of the Software except as permitted by law.

## 6. Support & Maintenance
Support and maintenance services, if included with the subscription, are provided in accordance with Licensor’s then-current support terms published at the Licensor website.

## 7. Intellectual Property
Licensor retains all rights, titles, and interest in and to the Software, including all related intellectual property rights.

## 8. Protections & Compliance
1. **Confidentiality**: Licensee shall treat any source code, license keys, support materials, and related non-public information as confidential and shall not disclose them to third parties, except as necessary to exercise rights under this Agreement.

Licensee shall provide such records within thirty (30) days of receipt of the written request. Licensor shall treat all records provided by Licensee as confidential and shall use them solely for confirming compliance. Each party will bear its own costs associated with any audit, unless a material breach is discovered, in which case Licensee will reimburse reasonable audit costs.
3. **Export Controls & Sanctions**: Licensee agrees to comply with all applicable U.S. and international export laws and regulations and shall not transfer the Software to restricted jurisdictions or prohibited parties.
4. **Government Use**: If Licensee is a U.S. government agency or contractor, the Software is provided as “commercial computer software” and use is subject to restrictions in FAR 12.212 or DFARS 227.7202.
5. **Assignment & Change of Control**: Licensee may not assign, sublicense, or otherwise transfer this Agreement, by operation of law or otherwise, without Licensor’s prior written consent, which shall not be unreasonably withheld, except in the case of a merger or acquisition where the successor agrees to be bound by this Agreement.

## 9. Warranty Disclaimer, and Exclusive Remedies

1. The Software is provided “as is” without a warranty of any kind, express or implied.

2. Licensee must notify Licensor of any service deficiencies within thirty (30) days from performance of the defective services. LICENSOR DOES NOT GUARANTEE THAT THE SOFTWARE WILL PERFORM ERROR-FREE OR UNINTERRUPTED, OR THAT LICENSOR WILL CORRECT ALL SOFTWARE ERRORS.

3. FOR ANY BREACH OF THE ABOVE WARRANTIES, LICENSEE’S EXCLUSIVE REMEDY AND LICENSOR’S ENTIRE LIABILITY SHALL BE: (A) THE CORRECTION OF SOFTWARE ERRORS THAT CAUSE BREACH OF THE WARRANTY; OR, IF LICENSOR CANNOT SUBSTANTIALLY CORRECT SUCH BREACH IN A COMMERCIALLY REASONABLE MANNER, LICENSEE MAY END THE SUBSCRIPTION TERM AND RECOVER A PRORATED PORTION OF ANY LICENSE FEES PREPAID TO LICENSOR; OR (B) THE REPERFORMANCE OF THE DEFICIENT SUPPORT SERVICES.

All communications in connection with this Agreement will be in the English language.

5. **Severability.** If any of the parties’ obligations under this agreement are found by a court of competent jurisdiction to be illegal or unenforceable in any respect, such illegality or unenforceability will be interpreted to achieve the goals of such provision to the greatest extent possible under applicable law but shall not affect the other provisions of this agreement, all of which shall remain enforceable in accordance with their terms.

6. **No waiver.** The parties shall not be deemed to waive any of their rights or remedies under this agreement unless such a waiver is in writing and signed by the party to be bound. No delay or omission on the part of either party in exercising any right or remedy under this agreement will be construed to be a waiver thereof. A waiver of any right or remedy on any one occasion shall not be construed as a bar to or waiver of such right or remedy or any other right or remedy on any future occasion.

7. **Data Protection.** Licensee acknowledges that correspondence and log files generated in conjunction with a request for Support Services may contain sensitive, confidential, or personal information. Licensee is solely responsible for taking the steps it considers necessary to protect the data, including obfuscating the logs or otherwise guarding the information before sending it to Licensor.
