         D. Capitalized terms used but not otherwise defined herein shall have

services or (ii) that the Company, any of its Affiliated Corporations or
Executive has solicited with respect to the provision of waste services.

                  (c) "Time Period" means the period beginning as of the date of

Period shall mean the period beginning as of the date of this Agreement and
ending five years thereafter; provided, however, that if a court of competent
jurisdiction determines that such period is unenforceable, Time Period shall

thereafter; provided, however, that if a court of competent jurisdiction
determines that such period is unenforceable, Time Period shall mean the period
beginning as of the date of this Agreement and ending three years thereafter;
provided, however, that if a court of competent jurisdiction determines that

number of days in any period in which Executive is in default or breach of this
Agreement.

         2. PAYMENT. As full consideration for Executive entering into this
Agreement, the Company shall pay to Executive or a person or entity designated
by Executive the sum of [$700,000/700,000/300,000/300,000], which sum shall be
payable in 7 equal annual installments of $________, with the first such
installment due within 10 days after the consummation of the transactions
contemplated by the Merger Agreement, and subsequent annual installments due on
the annual anniversary of the date of this Agreement for the 6 years thereafter.
If the Company fails to make any such annual payment within 30 days after the
date it is due, all amounts remaining to be paid under this Agreement shall
accelerate and become immediately due and payable upon written demand by
Executive. Following any such acceleration, Executive shall no longer be bound
by the covenants in this Agreement until such time as the Company has paid
Executive all amounts due Executive under this Agreement, including accelerated
amounts. Notwithstanding anything herein to the contrary, the Company shall not
be obligated to make any payment to Executive during such time as Executive is
in default or breach of this Agreement.

         3. COVENANTS. Executive covenants and agrees that, during the Time
Period, Executive shall not, directly or indirectly, individually or as a
stockholder, partner, member, financier, agent, employee, representative or
consultant for or otherwise on behalf of or in conjunction with any Person:

                  (a) NONCOMPETITION. Engage or have any interest, direct or
indirect, in any business in competition with the Businesses, as the Businesses
are constituted on the date hereof (whether or not the Businesses are
subsequently carried on by the Company, the Affiliated Corporations or by any
successor or subsequent purchaser of the Businesses), within the Area; provided,
however, that this shall not preclude Executive from: (i) owning less than 1% of
the securities of any publicly traded entity; or (ii) owning J. R. Capital, Inc.
("J.R.") and conducting through J. R. the business of C&D recycling, transfer
and disposal at J.R.'s facilities at Homestead, Riviera Beach, Lox Road, Davie,

Delta Recycling, Inc. dated November 1, 1999 as in effect on the date of the
Merger Agreement. Notwithstanding clause (ii) above, however, J.R. shall be
precluded from conducting hauling operations, from expanding its business in
competition with the Businesses to facilities other than those listed above, and
from subcontracting with any




                                       2

person or entity other than the Company to perform the services presently
performed by the Company under the Star Agreement.

                  (b) NONSOLICITATION OF CUSTOMERS. Solicit or assist in the

         4. ENFORCEABILITY. Executive represents and warrants to and covenant
with the Company as follows:

                  (a) The covenants in this Agreement are reasonably necessary
for the protection of the interests of the Company and the Affiliated
Corporations, are reasonable as to duration, scope and territory, and are not
unreasonably restrictive of Executive.

                  (b) If Executive breaches any covenants set forth in this
Agreement, such breach would cause irreparable harm to the Company and the
Affiliated Corporations. In the event it is judicially determined that Executive
has breached any such covenants, the Company and the Affiliated Corporations
shall be entitled, in addition to monetary damages and to any other remedies
available to the Company and the Affiliated Corporations under this Agreement
and at law, to equitable relief, including injunctive relief, and the payment by
Executive of all costs incurred by the Company and the Affiliated Corporations
in enforcing the provisions of this Agreement, including reasonable attorneys'
fees.

                  (c) Notwithstanding subsection (a), should any court of
competent jurisdiction determine that any covenants in this Agreement are
unreasonable as to duration, scope, or territory, the covenants shall be
enforceable as provided in this Agreement with respect to the maximum duration,
scope and territory as the court determines to be reasonable.

         5. ASSIGNMENT; BINDING EFFECT; AMENDMENT. This Agreement and the rights
of the parties under it may not be assigned (except by operation of law, except
that they may be assigned by the Company to an affiliate of the Company or to
any successor of the Company to the Businesses without the consent of Executive,
and except that Executive may assign his rights, but not his obligations, under
this Agreement to an entity of which he owns a majority of the voting interests
without the consent of the Company) and shall be binding upon and shall inure to
the benefit of the parties. In addition, this Agreement shall inure to the
benefit of: (a) the Affiliated Corporations; and (b) Executive's estate in the
event of Executive's death, in which case the Company shall continue to make
payments under this Agreement to Executive's estate as and when they would have
been made to Executive. This Agreement constitutes a valid and binding agreement
of the parties enforceable in accordance with its terms and may be modified or
amended only by a written instrument executed by each party.

         6. ENTIRE AGREEMENT. This Agreement is the final, complete and
exclusive statement of the agreement among the parties with relation to the
subject matter of this Agreement. There

         10. NO WAIVER. No delay of or omission in the exercise of any right,
power or remedy accruing to any party as a result of any breach or default by
