  We investigate the classical integrability of the Alday-Arutyunov-Frolov
model, and show that the Lax connection can be reduced to a simpler 2 x 2
representation. Based on this result, we calculate the algebra between the
L-operators and find that it has a highly non-ultralocal form. We then employ
and make a suitable generalization of the regularization technique proposed by
Maillet for a simpler class of non-ultralocal models, and find the
corresponding r- and s-matrices. We also make a connection between the
operator-regularization method proposed earlier for the quantum case, and the
Maillet's symmetric limit regularization prescription used for non-ultralocal
algebras in the classical theory.
