            RE:   Engineered Products Sales Associates

Dear Mr. Beck:

            Please be advised that this firm represents Engineered Products
Sales Associates ("EPSA") in conjunction with its relationship with Conversion
Technologies International, Inc. ("CTI"). As you are likely aware, EPSA has not
received approximately $10,000 in commissions which it is owed by CTI. Such
commissions are well past due. Failure to pay these sums constitutes a material
breach of CTI's continuing obligations to EPSA pursuant to the Manufacturer
Representative Agreement between these parties, which was terminated by CTI,
effective August 1,1998. Therefore, if CTI fails to fully satisfy its
outstanding payment obligations to EPSA on or before October 30, 1998, EPSA's
obligations to CTI will be null and void and of no force or effect.

            Should you have any questions or concerns regarding the foregoing,
please feel free to call me.

                                                     Sincerely,


                                                     /s/ Steven M. Reinsel
                                                     ---------------------------
