                      The Licensed Work is © 2026 Shankar Kambam.

Additional Use Grant: You may make use of the Licensed Work, including in
                      production for your internal business operations and
                      for operations that provide products or services to
                      your own customers, provided that you may not offer
                      the Licensed Work as a Commercial Certificate Service.

                      A "Commercial Certificate Service" is a product or
                      service whose principal value to a third party is the
                      certificate management functionality of the Licensed
                      Work — including but not limited to lifecycle
                      management, discovery, monitoring, alerting, renewal
                      automation, deployment, and revocation — where the
                      third party accesses or controls that functionality
                      and compensation is received for that access or
                      control.

                      For the avoidance of doubt:

                      (a) you may run the Licensed Work in production to
                          manage certificates for products or services
                          that you offer to your customers, where the
                          principal value of those products or services is
                          something other than the Licensed Work's
                          certificate management functionality (for
                          example, you operate a banking application and
                          use the Licensed Work internally to manage TLS
                          certificates for that application);

                      (b) for the purposes of this Additional Use Grant,
                          "third party" excludes (i) your employees, (ii)
                          your contractors acting on your behalf, and (iii)
                          your Affiliates. "Affiliate" means any entity
                          that controls, is controlled by, or is under
                          common control with, you, where "control" means
                          ownership of more than fifty percent (50%) of
                          the voting interests of the entity;

                      (c) the restriction on offering a Commercial
                          Certificate Service applies regardless of whether
                          the Licensed Work is hosted, managed, embedded,
                          bundled, or integrated with another product or
                          service.
