         THIS UNCONDITIONAL CONTINUING GUARANTY OF LEASE made this 20th day of
February, 1998, by and between HI-RISE RECYCLING SYSTEMS, INC., a Florida
corporation, 8505 N.W. 74th Street, Miami, Florida 33166, Fax (305) 594-4228
(hereinafter called "Guarantor") and EVELIO ACOSTA and GLADYS ACOSTA, (
hereinafter called "Landlord").

         WHEREAS, HESCO SALES, INC., a Florida corporation, a wholly owned
subsidiary of Guarantor, (hereinafter called "Corporation"), wishes to lease
from Landlord certain premises located in Hialeah, Florida, and enter into a
lease agreement (the "Lease"); and

         WHEREAS, Guarantor has a financial interest in Corporation and Landlord
is unwilling to enter into the Lease with Corporation unless it receives an
unconditional and continuing guaranty from Guarantor as to all obligations
arising under the Lease; and

         WHEREAS, Guarantor is desirous that Landlord enter into the Lease with
Corporation.

         NOW, THEREFORE, in consideration of the premises and of other good and
valuable consideration, and in order to induce Landlord to enter into the Lease
with Corporation, Guarantor hereby absolutely and unconditionally guarantees to
Landlord and its successors and assigns, the full and prompt payment of any
amounts due or to become due to Landlord under the Lease and the full payment
and performance of all Corporation's obligations to Landlord under the Lease.

         Guarantor covenants and agrees

         1. Guarantor expressly agrees to pay all legal expenses and reasonable
attorneys' fees (including those relative to appellate proceedings, if any)
actually incurred by Landlord in any collection relative to the obligations
hereby guaranteed or in enforcing this Guaranty against the undersigned.

         2. This Guaranty will continue unchanged by any bankruptcy,
reorganization or insolvency of Corporation or any successor or assignee thereof
or by any disaffirmance or abandonment by a trustee of Corporation.

         3. This Guaranty is and shall remain an unconditional and continuing
guaranty of payment and performance and not of collection, shall remain in full
force and effect. To that end, Guarantor hereby expressly waives any right to
require Landlord to bring any action against Corporation or any other person(s)
or to require that resort be had to any security. Guarantor acknowledges that
its liabilities and obligations hereunder are primary rather than secondary.

         4. Time is of the essence hereof. Any notice(s) to Guarantor shall be
sufficiently given, if mailed by certified mail, postage prepaid, return receipt
requested, or by overnight delivery services or by facsimile to the first above
stated address(es) of Guarantor.

         5. This Unconditional Continuing Guaranty of Lease shall be binding
upon Guarantor, and the legal representatives, successors and assigns of
Guarantor, and it shall inure to the benefit of, and be enforceable by Landlord,
and its successors, transferees and assigns. It further shall be deemed to have
been made under and shall be governed by the Laws of the State of Florida in all
respects, including matters of construction, validity and performance.

         6. No waiver by Landlord or any default(s) by Guarantor or Corporation

same default on a future occasion. If more than one person has signed this
Guaranty, such parties are jointly and severally obligated hereunder. Further,
use of the masculine or neuter pronoun herein shall include the masculine,

obligations of Corporation under the Lease; (iii) protest or notice of dishonor
