  In arXiv:0910.5670 we suggested that the Nekrasov function with one
non-vanishing deformation parameter \epsilon is obtained by the standard
Seiberg-Witten contour-integral construction. The only difference is that the
Seiberg-Witten differential pdx is substituted by its quantized version for the
corresponding integrable system, and contour integrals become exact monodromies
of the wave function. This provides an explicit formulation of the earlier
guess in arXiv:0908.4052. In this paper we successfully check this suggestion
in the first order in \epsilon^2 and the first order in instanton expansion for
the SU(N) model, where non-trivial is already consistency of the so deformed
Seiberg-Witten equations.
