accordance with Sections 1.2 and 1.3 constitute an "investment unit" for the

     SECTION 4.1 Corporate Existence, etc. The Company will at all times
preserve and keep in full force and effect its corporate existence. The Company
will at all times preserve and keep in full force and effect the corporate
existence of each of its Subsidiaries (unless merged into the Company or one of
its Subsidiaries) and all rights and franchises of the Company and its
Subsidiaries unless, in the good faith judgment of the Company, the termination
of or failure to preserve and keep in full force and effect such corporate
existence, right or franchise could not, individually or in the aggregate, have
a Material Adverse Effect.

     SECTION 4.2 Corporate Existence; Subsidiaries; Maintenance of Properties.
Each of the Company and its Subsidiaries will preserve and keep in full force
and effect its corporate existence, rights and franchises except for any
Subsidiary of the Company which is combined or merged with and into the Company.

replacements, betterments and improvements thereof, all as in the judgment of
the

<PAGE>

Company may be necessary so that the business carried on in connection therewith
may be properly and advantageously conducted at all times; provided, however,
that nothing in this Section 4.2 shall prevent the Company or any of its
Subsidiaries from discontinuing the operation and maintenance of any of such
properties if such discontinuance is, in the judgment of the Company, desirable
in the conduct of such Person's business and does not cause a Material Adverse
Effect.

     SECTION 4.3 Insurance. Each of the Company and its Subsidiaries will
maintain with financially sound and reputable insurance companies, funds or

regulations to which each of them is subject and will obtain and maintain in
effect all licenses, certificates, permits, franchises and other governmental
authorizations necessary to the ownership of their respective properties or to
the conduct of their respective businesses, in each case to the extent necessary
to ensure that non-compliance with such laws, ordinances or governmental rules
or regulations or failures to obtain or maintain in effect such licenses,
certificates, permits, franchises and other governmental authorizations could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

     SECTION 4.5 Taxes. The Company will and will cause each of its Subsidiaries
to file all tax returns required to be filed in any jurisdiction and to pay and
discharge all taxes shown to be due and payable on such returns and all other

and all claims for which sums have become due and payable that have or might
become a Lien on properties or assets of the Company or any such Subsidiary,
provided that neither the Company nor any such Subsidiary need pay any such tax
or assessment or claims if (i) the amount, applicability or validity thereof is
contested by the Company or such Subsidiary on a timely basis in good faith and
in appropriate proceedings, and the Company or such Subsidiary has established
adequate reserves therefor in accordance with GAAP on the books of the Company
or such Subsidiary or (ii) the nonpayment of all such taxes and assessments in
the aggregate could not reasonably be expected to have a Material Adverse
Effect.

Days of receiving notice (describing with reasonable particularity the books and
records to be reviewed), the Company and its Subsidiaries shall permit Investor

         FOR VALUE RECEIVED, the undersigned, ONCURE TECHNOLOGIES CORP., a
Florida corporation ("Company"), hereby promises to pay to the order of ALPINE
VENTURE CAPITAL PARTNERS LP, a Delaware limited partnership ("Holder") and its
assigns, the principal sum of ONE MILLION DOLLARS ($1,000,000) on May 15, 2003
(the "Maturity Date"), with interest thereon from time to time as provided
herein.

         This Convertible Promissory Note (this "Note") is issued in connection
with the execution of that certain Purchase Agreement, dated May 15, 2002 (the
"Purchase Agreement"), between Company and Holder. All capitalized terms used
but not defined herein shall have the respective meanings assigned thereto in
the Purchase Agreement.

1. Purchase Agreement. This Note is issued by the Company, on the date hereof,
pursuant to the Purchase Agreement and is subject to the terms thereof. The
Holder is entitled to the benefits of this Note and the Purchase Agreement, as
it relates to this Note, and may enforce the agreements of the Company contained
in this Note and the Purchase Agreement and exercise the remedies provided for
in this Note and the Purchase Agreement or otherwise available in respect hereto
and thereto. Capitalized terms used herein and not defined herein shall have the
meanings ascribed to such terms in the Purchase Agreement.

2. Interest.

     2.1. Generally. The Company promises to pay interest ("Interest") on the
principal amount of this Note at the rate of 8.00% per annum (the "Interest
Rate"). Interest on this Note shall accrue from the date hereof through and
until repayment of the principal amount of this Note and payment of all Interest
in full and shall be computed on the basis of a 360-day year of twelve 30-day
months. Interest shall be paid quarterly in arrears on each March 31, June 30,
September 30 and December 31 of each year or, if any such date shall not be a
Business Day (as defined below), on the next succeeding Business Day to occur
after such date (each date upon which interest shall be so payable, an "Interest
Payment Date"). In addition, in the event of any prepayment of principal of this
Note (in accordance with Section 3 below), such prepayment shall be accompanied
by the interest accrued on the amount so prepaid. Interest on this Note shall be
paid in cash by wire transfer of immediately available funds to an account at a
bank designated in writing by the Holder. The term "Business Day" shall mean any
day other than a Saturday, Sunday or other day on which commercial banks in West
Palm Beach, Florida are authorized or required by law or executive order to

     2.2. Default Rate of Interest. Notwithstanding the foregoing provisions of
this Section 2, but subject to applicable law, any overdue principal of and
overdue Interest on this Note shall bear interest, payable on demand in
immediately available funds, for each day from the date payment thereof was due
to the date of actual payment, at a rate equal to the sum of the Interest Rate
and an additional 2.00% per annum. Subject to applicable law, any interest that
shall have accrued on overdue interest on this Note as provided in the preceding
sentence and that shall not have been paid in full on or before the next
Interest Payment Date to occur after the date on which the overdue interest
became due and payable shall itself be deemed to be overdue interest on this
Note to which the preceding sentence shall apply.

     2.3. No Usurious Interest. In the event that any interest rate(s) provided
for in this Section 2, shall be determined to be unlawful, such interest rate(s)
shall be computed at the highest rate permitted by applicable law. Any payment
by the Company of any interest amount in excess of that permitted by law shall
be considered a mistake, with the excess being applied to the principal amount
of this Note without prepayment premium or penalty; if no such principal amount
is outstanding, such excess shall be returned to the Company.

3. Prepayment. This Note may be prepaid, in whole or in part, at any time and
from time to time, without premium or penalty.

4. Payments. The payment or prepayment of principal under this Note shall be
payable in lawful money of the United States of America by check delivered to
the Holder's address indicated in Section 8 (or to any other address specified
by the Holder) or by wire transfer to an account specified in writing by the
Holder. Any payment under this Note shall be applied first to sums due under
this Note other than principal and interest, second to accrued interest and
third to any principal amount outstanding under this Note.

5. Conversion

     5.1. Automatic Conversion. Upon the closing of a Subsequent Financing (as
defined below), the unpaid principal amount of this Note, before any and all
accrued and unpaid interest thereon, shall automatically convert, without any
further action on the part of the Holder or the Company, into 500 shares of the
Company's Series H Cumulative Accelerating Redeemable Preferred Stock (the
"Series H Preferred Stock"). For purposes of this Note, the term "Subsequent
Financing" means the sale by the Company to any Person or Persons, other than to
the Holder, of an aggregate of 500 shares of the Series H Preferred Stock and
the receipt by the Company of gross proceeds of at least $1,000,000 cash for
such 500 shares of Series H Preferred Stock.

     5.2. Conversion Procedure. On the First Business day immediately succeeding
the closing of the Subsequent Financing, the Holder shall surrender this Note at
the office of the Company and the Company shall issue and deliver at such office
of the Holder a certificate representing 500 shares of the Series H Preferred
Stock issued in the name of the Holder, together with an amount in cash equal to
all accrued and unpaid interest on the principal amount of this Note and all
other amounts, if any, then due and owing under this Note.

<PAGE>

     5.3. Issue Taxes. The Company shall pay any and all issue taxes,
documentary stamp taxes and other taxes that may be payable in respect of the
issuance or delivery of this Note or shares of the Series H Preferred Stock
issued or delivered upon conversion hereof.

and continuation for any reason whatsoever of any of the following events shall
