     Compensation of Directors

               Each director who is not an employee of Earth Technology 
     receives stock options in lieu of 100% of fees.  The number of options
     granted each quarter to any eligible director is equal to the
     quarterly director fee of $3,750 divided by 75% of the fair market
     value of Earth Technology Common Stock as of the last day of each
     fiscal quarter.  The option price for these grants is equal to 25% of
     the fair market value of the Earth Technology Common Stock as of the
     last day of Earth Technology's fiscal quarter.  Options are granted
     quarterly on the last day of Earth Technology's fiscal quarter.

               Options become exercisable on the first day of the calendar
     year following the date of grant, provided that any options will
     become immediately exercisable upon the termination of the service of
     the director holding the option.  Options terminate upon the
     expiration of ten years from the date of grant but are not otherwise
     subject to forfeiture.

     Employment Agreements

               Each named officer of Earth Technology, except Dr. Holbrook,
     has a written employment agreement with Earth Technology.  Diane C.
     Creel, Richard R. Pannell and Creighton K. Early have employment
     agreements with an indefinite term.  Earth Technology may terminate
     such agreements upon twelve months written notice:  the employee may
     terminate upon 30 days written notice.  Further, the agreements
     provide that Mrs. Creel shall hold the position of Chief Executive
     Officer, at a minimum annual salary of $195,000, Mr.

                                    121





     Pannell shall hold the position of President - Consulting Operations
     at a minimum annual salary of $164,000, and Mr. Early shall hold the
     position of Chief Financial Officer at a minimum annual salary of
     $140,000.  The guaranteed minimum salaries are automatically revised
     upward upon the granting of a salary increase by the Board of
     Directors.  The employment agreement with Mr. Colonna also has an
     indefinite term.  Either party to the agreement must give twelve
     months written notice to terminate.  The agreement with Mr. Colonna
     provides that he shall hold the position of Senior Vice President with
     a guaranteed minimum annual salary of $140,000.

               Earth Technology and Ms. Creel have entered into an
     amendment to Ms. Creel's employment contract, which became effective
     upon the consummation of the May 1994 merger with Summit.  Under the
     terms of the amendment, the term of Ms. Creel's employment was
     extended until December 31, 1998, with an automatic one year extension
     commencing on that date and each subsequent December 31st, unless
     Earth Technology or Ms. Creel gives twelve months notice of non-
     extension prior to an extension date.  If Ms. Creel's employment is
     terminated by Earth Technology "without cause" or by Ms. Creel for
     "good reason" (each as defined in the employment agreement), Ms. Creel
     will continue to receive the annual salary and bonus otherwise payable
     to her under her employment agreement as if Ms. Creel continued to be
     employed for the longer of (i) the remaining term of the employment
     agreement or (ii) 18 months.  Ms. Creel will also be entitled to the
     continuation of fringe benefits for the remainder of her employment
     term.

               Ms. Creel and Messrs. Pannell and Early are entitled to
     certain severance benefits in the event Earth Technology either
     terminates their employment without proper cause and notice or
     materially breaches the terms of their agreements.  These benefits
     include lump sum payment of 12 months' salary (18 months' in the case
     of an intentional material breach), accumulated pro rata bonus and
     continuation of certain benefits for 12 months.  With regard to Mr.
     Colonna, if Earth Technology merges or consolidates with, or transfers
     substantially all of its assets to another corporation, and if his
     employment agreement is not assigned to the successor corporation,
     then he will be entitled to a lump sum payment of 12 months' salary
     and continuation of certain benefits.

     Compensation Committee Interlocks and Insider Participation

               The Compensation Committee is composed of Richard J.
     Heckmann, Chairman; James E. Clark; and Charles D. Applequist.  No
     member of the Compensation Committee is a former or current officer or
     employee of the Earth Technology.  At the Effective Time, Mr. Ward W.
     Johnson will be appointed to the Compensation Committee.  His
     appointment is a condition to HazWaste's obligations under the Merger
     Agreement.

     Board Report on Executive Compensation

               The Compensation Committee of the Earth Technology Board of
     Directors, which is comprised entirely of independent outside
     directors, is responsible for reviewing and approving Earth
     Technology's executive compensation policies and plans.  No member of
     the Compensation Committee is a former or current officer or employee
     of Earth Technology or any of its subsidiaries.  From time to time,
