With this at hand we extend the integration of generalized subdifferentials and the characterization of convexity via the monotonicity of the subdifferential. Keywords: Approximate Mean Value Theorem, integration of subdifferentials, monotonicity of the subdifferential, epi-pointed functions, generalized subdifferentials. MSC: 49J53, 49J52.
