We study the low-energy dynamics in three-dimensional $\mathcal{N}=2$<br />
exceptional gauge theories with matters in a fundamental representation,<br />
especially focusing on confinement phases and on a quantum structure of the<br />
Coulomb branch in the moduli space of vacua. We argue that the confinement<br />
phases of these exceptional gauge theories have a single Coulomb branch. The 3d<br />
s-confinement phases for the exceptional gauge groups are associated with<br />
quantum-deformed moduli spaces of the corresponding 4d $\mathcal{N}=1$<br />
exceptional gauge theories.
