AMENDMENT TO WARRANT CERTIFICATE

          THIS AMENDMENT TO WARRANT CERTIFICATE (the "Amendment") relates to a
certain Warrant Certificate dated July 11, 1994 (the "Warrant Certificate"),
granted by EVANS ENVIRONMENTAL CORPORATION, a Colorado corporation, to
STRATEGICA GROUP, INC., a Florida corporation, with respect to 350,000 shares of
Evans' common stock.

          Section 1 of the Warrant Certificate is hereby amended in its entirety
to read as follows:

          "Section 1. EXERCISE OF WARRANT. This Warrant may be exercised at any
          time from the date hereof until and including January 11, 1999, 5:00
          P.M., Miami, Florida time (the "Expiration Date"). If the average of
          the closing bid and asked prices of the Company's Common Stock for the
          ten (10) trading days (in which the Company's Common Stock is traded)
          immediately prior to January 11, 1999, is less than $2.00 per share on
          the original Expiration Date, then the Expiration Date shall be
          extended for one additional year to January 11, 2000 (the "First
          Extended Expiration Date"). If such average immediately prior to
          January 11, 2000, is less than $2.00 per share on the First Extended
          Expiration Date, then the Expiration Date shall be extended for one
          additional year to January 11, 2001 (the "Second Extended Expiration
          Date"). If such average immediately prior to January 11, 2001, is
          less than $2.00 per share on the Second Extended Expiration Date, then
          the Expiration Date shall be extended for one additional year to
          January 11, 2002. Subject to adjustment pursuant to Section 4 below,
          the exercise price of the shares of Common Stock purchasable pursuant
          to this Warrant shall be $0.675 per share (such price, as adjusted
          from time to time, being hereinafter referred to as the "Exercise
          Price"). The rights represented by this Warrant may be exercised by
          the holder hereof, in whole or in part, but not as to a fractional
          share of Common Stock, by the surrender of this Warrant (properly
          endorsed) at the office of the Corporation or its transfer agent, and
          by payment to the Corporation of the Exercise Price in cash or by wire
          transfer, for each share being purchased. Upon the exercise of this
          Warrant, a certificate or certificates for the shares of Common Stock
          so purchased, registered in the name of the holder, shall be promptly
          delivered to the holder hereof within a reasonable time. The person in
          whose name any certificate for shares of Common Stock is issued upon
          exercise of this Warrant shall for all purposes be deemed to have
          become the holder of record of such shares on the date on which the
          Warrant was surrendered and payment of the Exercise Price and any
          applicable taxes was

<PAGE>

          made, except that, if the date of such surrender and payment is a date
          on which the stock transfer books of the Corporation are closed, such
          person shall be deemed to have become the holder of such shares at the
          close of business on the next succeeding date on which the stock
          transfer books are open."

          Except as amended hereby, the terms and conditions of the Warrant
Certificate shall remain the same and in full force and effect.

          IN WITNESS WHEREOF, this Amendment has been executed as of this 4 day
of April, 1995.
