ITEM 1.           SECURITY AND ISSUER.

This Schedule 13D relates to the acquisition of beneficial ownership of Common

Cypress Creek Road, Suite 400, Fort Lauderdale, Florida 33309.

ITEM 2.           IDENTITY AND BACKGROUND.

The persons filing this Schedule 13D are Active Investors II, Ltd., a Florida
limited partnership ("Active II"); Active Investors III, Ltd., a Florida limited
partnership ("Active III") and Fundamental Management Corporation, a Florida
corporation ("Fundamental" and together with Active II and Active III, the
"Reporting Persons"). The principal business and office address for each of
Active II, Active III and Fundamental is 8567 Coral Way, #138, Miami, Florida
33155. Information as to the identity and background of the executive officers,

herein. Active II and Active III are private investment funds. Fundamental is
the sole general partner of Active II and Active III, which is its principal
business.

During the last five years, none of the Reporting Persons and, to the knowledge
of the Reporting Persons, none of the Principals, (i) have been convicted in any
criminal proceeding (excluding traffic violations or similar misdemeanors); or
(ii) were a party to a civil proceeding of a judicial or administrative body of

Stock. Each share of Series A Preferred Stock is convertible into 1,000 shares

Common Stock, which gives Active III beneficial ownership of 913,000 shares of

--------------------------------------------------------------------------------

ITEM 4.           PURPOSE OF TRANSACTION.

The shares of Series A Preferred Stock were acquired by Active II and Active III
for investment purposes.

In the ordinary course of the businesses, the Reporting Persons from time to

time in the future a variety of alternatives, including, without limitation: (a)
the acquisition of additional securities of the Issuer or the disposition of
securities of the Issuer; (b) an extraordinary corporate transaction, such as a
merger, reorganization or liquidation, involving the Issuer or any of its
subsidiaries; (c) a sale or transfer of a material amount of assets of the
Issuer or any of its subsidiaries; (d) a change in the present board of
directors or management of the Issuer; (e) material changes in the present
capitalization or dividend policy of the Issuer; (f) other material changes in
the Issuer's business or corporate structure; (g) changes in the Issuer's
charter, bylaws or instruments corresponding thereto or other actions which may
impede the acquisition of control of the Issuer by any person; (h) causing a
class of securities of the Issuer to be delisted from a national securities
exchange or cease to be authorized to be quoted in an inter-dealer quotation
system of a registered national securities association; (i) a class of equity
securities of the Issuer becoming eligible for termination of registration
pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934; or (j) any
action similar to any of those enumerated above. There is no assurance that the
Reporting Persons will develop any plans or proposals with respect to any of the
foregoing matters. Any alternatives which the Reporting Persons may pursue will
depend upon a variety of factors, including, without limitation, current and
anticipated future trading prices for the Common Stock, the financial condition,
