Finally, we prove that a semigroup of self mappings $T = \{T(t) : t \in G\}$ on a nonempty convex weakly compact subset $\overline{C}$ of a Banach space with a weak uniform normal structure $X$, such that $\lim \inf_{G
i t\rightarrow\infty}| \|T(t)\| | = \lim_{G
i t\rightarrow\infty}| \|T(t)\| |=k < WCS(X)\mu_0$ admits a common fixed point where $\mu_0=\inf\{\mu\geq1 : \mu(1-\delta_X(1/\mu))\geq(1/2)\}$, and $WCS(X)$ is the weakly convergent sequence coefficient of $X$ while $| \|T(t)\| |$ is the exact Lipschitz constant of $T(t)$.
