Sec.  27.603   Access to the Guard Band Manager's spectrum.

   (a) A Guard Band Manager may not engage in unjust or unreasonable
   discrimination among spectrum users and may not unreasonably deny
   prospective spectrum users access to the Guard Band Manager's licensed
   spectrum.

   (b) A Guard Band Manager may not impose unduly restrictive requirements on
   use of its licensed frequencies, including any requirement that is not
   reasonably related to the efficient management of the spectrum licensed to
   the Guard Band Manager.

   (c) A Guard Band Manager may lease a reasonable amount of its spectrum to an
   affiliate for the affiliate's own internal use or for the affiliate's
   provision of commercial or private radio services. However, a Guard Band
   Manager must lease the predominant amount of its spectrum to non-affiliates.
