                      The Licensed Work is © 2026 certctl LLC.

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 any product
                      or service that provides third parties with access
                      to or control of any substantial set of the
                      certificate management functionality of the Licensed
                      Work — including but not limited to lifecycle
                      management, discovery, monitoring, alerting, renewal
                      automation, deployment, revocation, certificate
                      authority operation, certificate issuance,
                      certificate signing, or any combination thereof —
                      where compensation, in any form, is received in
                      connection with such access or control. This
                      restriction applies irrespective of whether such
                      functionality is the principal, ancillary,
                      supporting, or one of several values provided by the
                      product or service, and irrespective of whether the
                      Licensed Work is presented under its original name,
                      a modified name, or no name at all.

                      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 (1) directly or indirectly controls
                          you, (2) is directly or indirectly controlled by
                          you, or (3) is directly or indirectly under
                          common control with you, where "control" means
                          either (A) ownership of more than fifty percent
                          (50%) of the voting interests of the entity, or
                          (B) the power to direct the management and
                          policies of the entity, whether through voting
                          securities, contract, or otherwise;

                      (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.
