06820.("CARMICHAEL").

and Waste Management, Inc. et.al., dated August 14, 2000 (the "Closing Date");

      WHEREAS, CARMICHAEL, Synagro and BIO GRO desire and agree to dissolve any
prior employment relationship that may have existed between BIO GRO and

herein contained, and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, it is mutually covenanted and
agreed by and between the parties as follows.

individual and company performance and is paid in equal installments in
accordance with SYNAGRO's pay policy, but not less frequently than monthly.

shall be paid. Any such bonus paid will be discretionary and based on the
financial performance of the companies and CARMICHAEL's individual job
performance as determined by SYNAGRO management. CARMICHAEL will be eligible to
participate in the bonus program at the Division President level.

<PAGE>
            (c)   CARMICHAEL acknowledges and agrees that the limitations
imposed by this non-competition covenant as to time, geographical area, and
scope of activity being restrained are reasonable and do not impose a greater
restraint than is necessary to protect the goodwill or other business interest
of SYNAGRO. CARMICHAEL further acknowledges that the stock options referred to
in Section 2 and severance provisions of Section 3 above are given in exchange

the reductions in value between this Agreement and his prior employment
agreement with BIO GRO.

entity of which such person is an executive officer, director, partner, trustee
or other fiduciary or is directly or indirectly the beneficial owner of 10% or
more of any class of equity security thereof or other financial interest
therein; (ii) if such person is an individual, the spouse of such individual,
and any entity of which his spouse is an executive officer, director, partner,
trustee or other fiduciary or is directly or indirectly the beneficial owner of
10% or more of any class of equity security thereof or other financial interest
therein; (iii) if such person is an entity, any director, executive officer,
partner, trustee or other fiduciary or any direct or indirect beneficial owner
of 10% or more of any class of equity security of, or other financial interest
in, such entity; or (iv) any person that directly, or indirectly through one or
more intermediaries, controls, is controlled by, or is under common control with

waste disposal.

      11.   REMEDIES. CARMICHAEL agrees that this Agreement is intended to
protect and preserve legitimate business interests of SYNAGRO. It is further
agreed that any breach of this Agreement may render irreparable harm to SYNAGRO.
In the event of a breach by CARMICHAEL, SYNAGRO shall have available to it all
remedies provided by law, including, but not limited to, permanent injunctive
relief to restrain CARMICHAEL from violating this Agreement. SYNAGRO shall also
be entitled to commence legal action against CARMICHAEL for any breach of any
confidentiality agreement and/or confidentiality programs in effect at any time
between CARMICHAEL and SYNAGRO. Notwithstanding any legal remedies available to
SYNAGRO as a result of a breach of this Agreement, in the event of a breach by
CARMICHAEL, SYNAGRO shall immediately be entitled to withhold and avoid payment
of any sums of money or other benefits then due or to become due under this or
any other Agreement between CARMICHAEL and SYNAGRO.

      12.   REFORMATION OF COVENANTS. CARMICHAEL acknowledges that the covenants
contained in Sections 9 and 10 are reasonable in geographical and temporal scope
and in all other respects. If any court determines that any of such covenants,
or any part thereof, are unenforceable, then (a) the remainder of such covenants
shall not be affected by such determination and (b) those


                                  Page 6 of 8
<PAGE>
of such covenants that are determined to be unenforceable because of the
duration or scope thereof shall be reformed by the court to reduce their
duration or scope so as to render the same enforceable against CARMICHAEL.

      13.   CONFLICTS WITH EMPLOYEE HANDBOOK. CARMICHAEL understands and agrees
that it is his responsibility to obtain and read the SYNAGRO Employee Handbook
and to abide by the rules, policies, and standards set forth in this Employee

revise, delete, and add to the provisions of the SYNAGRO Employee Handbook.
Before implementation, all such revisions, deletions, or additions to this
Employee Handbook must be in writing and must be signed by the Chief Executive
Officer, President, or Chief Financial Officer of SYNAGRO. No oral statements or
representations can change the provisions of the SYNAGRO Employee Handbook or
this employment agreement. CARMICHAEL and SYNAGRO further understand that
CARMICHAEL's employment agreement controls in the event of any conflicts with
the SYNAGRO Employee Handbook.

      14.   GENERAL PROVISIONS.

         a. NO WAIVER. The failure of SYNAGRO to terminate this Agreement for
the breach of any condition or covenant herein by CARMICHAEL shall not affect
SYNAGRO's right to terminate for subsequent breaches of the same or other
conditions or covenants. The failure of either party to enforce at any time or
for any period of time any of the provisions of this Agreement shall not be
construed as a waiver of such provisions or of the right of the party thereafter
to enforce each and every such provision.

         c. ASSIGNMENTS. The rights and obligations of the parties under this
Agreement may not be assigned without the consent of the parties hereto;
provided, however, that in the event of any reorganization or restructuring of
SYNAGRO in which the business of SYNAGRO or BIO GRO is transferred to an

shall automatically be assigned to such Affiliate, and the rights and
obligations of CARMICHAEL hereunder shall continue in effect.

federal courts located in Harris County, Texas.

         f. SEVERABILITY. Should any provision of this Agreement not be
enforceable in any jurisdiction, the remainder of the Agreement shall not be
affected thereby. However, if the covenant not to compete is deemed void or
voidable, then CARMICHAEL agrees to return the stock options granted as part of
this Agreement.
