Re:      Exim Internet Group, Inc. (formerly Hydro Environmental Resources,
         Inc.)


Commissioners:

We were previously the principal accountants for Exim Internet Group, Inc.
(formerly Hydro Environmental Resources, Inc.), and we reported on the financial
statements of Hydro Environmental Resources, Inc. as of December 31, 2004 and
2003, and for the two years then ended. We have not provided any audit services
to Exim Internet Group, Inc. since the audit of the December 31, 2004 financial
statements. On June 20, 2005, our appointment as principal accountants was
terminated. We have read Exim Internet Group, Inc.'s statements which we
understand will be filed with the Commission pursuant to Item 4 of Form 8-K, as
part of the Company's Form 8-K dated June 22, 2005. We agree with the statements
concerning our Firm in such Form 8-K.


Very truly yours,
