Implications of a small Fermi surface are discussed. We demonstrate that superconductivity in this system can be described in terms of two coupled condensates. The two condensates result in a collective excitation corresponding to a relative phase oscillation, a phason. We discuss the possibility of searching for this collective excitation in the dynamic resistance of a SQUID.
