     2. Consideration for Consulting Services. 
        -------------------------------------

     (a) In  consideration  of the  Consultant's  performance  of the Consulting
Services  during  the  Term of this  agreement,  the  Company  shall  pay to the
Consultant a  consulting  fee of $8,000 per month,  payable  monthly in arrears,

subject  to the  vesting  provisions  to be set forth in a  non-qualified  stock
option agreement to be entered into by the parties.

     3. Reimbursement of Expenses.
        -------------------------

     The Company shall reimburse the Consultant for his reasonable out-of-pocket
expenses  incurred in connection  with the  Consulting  Services and approved in
advance by the Chief  Executive  Officer of the Company.  Reimbursement  for any
expenses as provided for herein shall be made to the  Consultant  within  thirty
(30) days  following  receipt by the  Company of  satisfactory  evidence  of the
incurrence  of such  expenses  and the  Consultant's  written  request  for such
reimbursement.

     4. Term.
        ----

     The term (the "Term") of this  Agreement  shall  commence on August 7, 1997
and shall end on August 7, 2000; provided,  however,  that this Agreement may be
extended by the mutual written agreement of the parties hereto.  Notwithstanding
the foregoing,  this Agreement may be terminated by either party in the event of
a material  breach by the other party if such  breach is not cured (if  curable)
within  30 days  following  written  notice  thereof.  Notwithstanding  anything
contained herein to the contrary, in the event that the Consultant is removed as
Chairman  of the Board of the Company by the Board of  Directors  of the Company
(other than as a result of a breach of fiduciary 


                                       3
<PAGE>

duty,  conviction  of a felony or  material  breach of this  Agreement),  unless
otherwise  agreed to by the  parties,  (i) this  Agreement  shall  automatically
terminate,  (ii) the  Consultant  shall receive a lump sum cash payment equal to
the amount of the then remaining money payments  hereunder  (calculated from the
date of termination  through March 1, 2000) and (iii) all unvested  options held
by the  Consultant  granted in accordance  with Section 2 (a) of this  Agreement
shall become immediately exercisable.

     5. Nondisclosure of Confidential Information.
        -----------------------------------------

     (a) The  Consultant  acknowledges  that the  Company  would be  irreparably
harmed if  confidential  information  relating to the business and strategies of
the Company and its  subsidiaries  were  disclosed to  competitors  or potential
competitors  of the Company and its  subsidiaries.  Accordingly,  the Consultant
shall not (i) disclose to any person,  firm,  corporation,  association or other
entity any Confidential Information (as defined below) for any reason or purpose
whatsoever  or (ii) make use of any such  Confidential  Information  for his own
purpose or for the  benefit of any person,  firm,  corporation,  association  or
other  entity  except the  Company or its  subsidiaries.  For  purposes  of this
Agreement,  the term  "Confidential  Information"  shall  mean  any  information
relating  to the  Company or any of its  subsidiaries  that the  Consultant  may
acquire  by  reason  of  his  association   with  the  Company  or  any  of  its
subsidiaries,  except for (i)  information  which is in the public domain at the
time of receipt thereof by the Consultant, (ii) information which, after receipt
thereof by the Consultant, becomes part of the public domain through no improper
act or omission of the  Consultant,  and (iii)  information  which was  lawfully
within the  Consultant's  possession  prior to the initial  commencement  of the
Consultant's  association  with  the  Company  or any of its  subsidiaries.  The
foregoing  provisions shall not preclude the use or disclosure by the Consultant
of Confidential  Information (i) in the performance of his obligations hereunder
or (ii) to the extent required by law.

     6. Restrictive Covenants.
        ---------------------

     (a) The  Consultant  acknowledges  the  highly  competitive  nature  of the
business  conducted  by the Company 

                                       4
<PAGE>


and its subsidiaries. Accordingly, as an inducement to the Company to enter into
this  Agreement  and in partial  consideration  of the  amounts  to be  received
hereunder,  the  Consultant,  shall  not,  during  the term  hereof  and for the
two-year period thereafter, (i) directly or indirectly engage in or represent in
any way any business  (such  business  being  referred to herein as a "Competing
Business") competing with the business of the Company or any of its subsidiaries
of converting  waste into glass and ceramic  products,  whether such  engagement
shall be as an officer, director, owner, employee, partner, or other participant
in any  Competing  Business,  (ii) assist  others in  engaging in any  Competing
Business in the manner described in clause (i) above, (iii) induce any employees
of the Company or any of its subsidiaries to terminate their employment with the
Company or any such subsidiaries or to engage in any Competing  Business or (iv)
induce any entity or person with which the Company or any of subsidiaries  has a
business  relationship  to  terminate  or  alter  such  business   relationship;
provided,  however,  that nothing  contained in this Section 6(a) shall prevent,
--------   -------
restrain or  otherwise  restrict  the  Consultant  from owning 5% or less of any
class of securities of any corporation so long as such securities are listed for
trade by  NASDAQ in the  over-the-counter  market  or are  traded on a  national
securities exchange.

     (b) The Consultant  understands  that the foregoing  restrictions may limit
his ability to earn a  livelihood  in a business  similar to the Business of the
Company and its subsidiaries,  but he nevertheless believes that he has received
and will receive sufficient  consideration and other benefits as a Consultant of
the Company as provided hereunder to justify such restrictions.

     7. Injunctive Relief.
        -----------------

     The Consultant  acknowledges that damages may not be an adequate remedy for
a breach of Section 6 or 7 hereof and agrees that injunctive  relief in favor of
the Company  would be an  appropriate  remedy for such  breach.  Nothing  herein
contained,  however, shall be construed as prohibiting the Company from pursuing
any remedies  which may be available to it for such breach or threatened  breach
or any other breach of this consulting Agreement.


                                       5

     8. No Breach of Duty.
        -----------------

     The Consultant  represents and warrants to the Company that the performance
by him of this  Agreement  will  not  breach  any  agreement  or duty to keep in
confidence  proprietary  information  acquired by it in  confidence  or in trust
prior to the Consultant's  engagement  hereunder or any duty not to compete with
any  party.  The  Consultant  further  agrees  that it shall not enter  into any
agreement in conflict herewith during the Term.

     9. Assignment.
        ----------

     This  Agreement  shall not be assignable by either party hereto without the
written consent of the other party hereto;  provided,  however, that the Company
                                            --------   -------
may assign this  Agreement to any  successor of the Company,  whether by merger,
consolidation,  transfer of all or  substantially  all its assets or  otherwise,
without the prior written consent of the Consultant.

     10. Severability.
         ------------

     Every provision of this Agreement is intended to be severable.  If any term
or provision  hereof is deemed unlawful or invalid in any  jurisdiction  for any
reason whatsoever, such unlawfulness or invalidity shall not affect the validity
of the  remainder  of this  Agreement  or the  enforceability  of  such  term or
provision  in any  other  jurisdiction.  To the  extent  that any  such  term or
provision  is held to be unlawful or invalid,  the parties  agree to reform such
term or provision in such a way which will be enforceable in the jurisdiction to
which such holding  applies,  and which will reflect,  as nearly as permissible,
the intention of the parties.

     11. Notices.
         -------

     All notices and other communications  required or permitted hereunder shall
be sufficient if delivered personally or sent by nationally recognized overnight
