+### Exclusions and limitations of TSC responsibilities
+
+The TSC and the project is not permitted to directly, or indirectly, solicit
+funds or financial sponsorship for the Node.js project itself; or to enter into
+any financial agreements on behalf of the project. Such activities remain the
+sole responsibility of the OpenJS Foundation. The TSC may, however, activity
+seek technical or other non-financial sponsorship for the project, such as
+donation of needed services, hardware, software, or other resources, provided
+that such sponsorship does not create a conflict of interest with the OpenJS
+Foundation or its other projects, or otherwise violate Foundation policies.
+
+Specific exclusions from the communication oversight responsibilities include:
+
+ * Brand marketing
+ * Fundraising and financial sponsorship of the project (including, but not
+   limited to, the OpenJS Foundation's own financial sponsorship of the project)
+ * Legal matters
+
+All communication from the project touching on these topics must be reviewed
+and approved by the Foundation.
+
+All uses of OpenJS Foundation-owned trademarks and intellectual property are,
+subject to the [OpenJS Foundation Trademark Policy](https://trademark-policy.openjsf.org/).
+This includes use of the marks -- in full or in part -- in domain names, social
+media account handles, event names and other similar identifiers.
+
+The TSC may establish and administer project-specific communication channels,
+such as social media accounts and discussion forums, administered under the
+oversight of the TSC, subject to the above requirements. Should such channels
+make any use of OpenJS Foundation-owned trademarks or intellectual property, the
+channels must be capable of being administered jointly by both the TSC and the
+Foundation.
+
+Nothing in this charter should be interpreted as preventing the Foundation
+from also publishing content on any channel under its control about any aspect
+of the project, including all technical aspects, so long as those communications
+are not presented as being endorsed by, or representative of, the TSC or the
+body of project contributors except when specifically approved by the TSC.
