Let (Xd) and (Yρ) be compact metric spaces‚ τ be a Lipschitz involution on (Xd) and η be Lipschitz involution on (Yρ). Suppose that  for all xX for all yY , A is a real subalgebra of C(Xτ) which contains Lip(Xdτ) and B is a real subalgebra of C(Yη) which contains Lip(Yρη). We prove that if T:AB is a surjetive -homogenous norm-additive in modulus map then there exists a unique bijection  such that  for all fA ‚ yY and . Applying this fact‚ we show that if  (Xd) and (Yρ) are compact metric spaces and  is a surjective -homogenous norm-additive in modulus map then there exists a Lipschitz homeomorphism  from  to such that  for all  and y
