In my humble opinion, the fact that a process is driven by energy influx does
not necessarily make this process endothermic. The point is that DeltaG
(change in Gibbs Free Energy) need not have the same sign as DeltaH (change
in enthalpy). If a process has a positive DeltaG, i.e. it has to be driven to
operate, it may have positive or negative DeltaH, which gives the heat
exchange.
