A subordinate to a geologist or geophysicist registered under this chapter, insofar as he or she acts solely in that capacity, is exempt from registration under the provisions of this chapter. This exemption, however, does not permit any subordinate to practice geology or geophysics for others in his or her own right or to use the title "professional geologist" or "professional geophysicist."
