      Re:   Promap Corporation

      On September 24, 2013 my appointment as auditor for Promap Corporation
ceased. I have read Promap Corporation's statements included under Item 4.01 of
its Form 8-K dated September 24, 2013 and agree with such statements, insofar as
they apply to me.

Very truly yours,

/s/ Ronald R. Chadwick, P.C.
