                              AND CRC PARTNERS LTD.


         THIS AGREEMENT made this 28th day of June, 2001 by and between CRC
Partners Ltd., a Florida Limited Partnership (hereinafter referred to as CRC)
and OnCure Technologies Corp., formerly U.S. CancerCare, Inc., a Florida
corporation with its principal place of business at 700 Ygnacio Valley Road,
Walnut Creek, California 94596 (hereinafter OnCure) (both hereinafter
collectively referred to as the Parties).

         WHEREAS, CRC previously was the holder of a Promissory Note in the
original principal amount of $300,000.00, the Maker of which was OnCure (the
Note), and the holder of 60,000 warrants to buy common stock at 2.00 per share.

         WHEREAS, OnCure and CRC entered into an Agreement dated August 9, 2000,
which in part granted to CRC the irrevocable right to convert the Note to
150,000 shares of Common Stock ($.01 par value) of OnCure (Common Stock) at any
time prior to May 1, 2001 upon delivery to OnCure of the Note, and

         WHEREAS, the Agreement further provided that in the event the 150,000
shares of Common Stock of OnCure were not registered with the Securities
Exchange Commission (Commission) and freely tradable without restriction on or
before May 1, 2001, OnCure (or its Successors and/or Assigns) would purchase the
Common Stock from CRC at a purchase price of $2.00 per share plus Ten (10%)
percent interest on the initial principal amount of the Note of $3,000,000.00
from date of conversion, and

         WHEREAS, CRC has delivered the Note to OnCure and has converted the
Note to Common Stock effective December 30, 2000 (Conversion Date), and

         WHEREAS, As part of the original promissory note agreement, OnCure
granted to CRC a warrant to acquire 60,000.00 shares of Common Stock at $2.00
per share, and

         WHEREAS, OnCure is agreeable to reducing the warrant exercise price to
$.01 per share for extension of the Put Right as more specifically set forth
herein; and

         WHEREAS, CRC is agreeable to exercising its warrant to acquire 60,000
shares at $.01 per share using accrued interest owed on the Note as
consideration for this exercise.

         NOW, THEREFORE, in consideration of the mutual promises contained
herein as well as other good and valuable consideration, the receipt and
adequacy of which is hereby acknowledged, the Parties, intending to be legally
bound, hereby agree as follows:

         1. RECITALS. The Parties hereby agree the above referenced recitals are
true and correct and are incorporated herein.

         2. RIGHT TO PUT. Commencing December 1, 2001 and continuing to June 1
2002, CRC shall have the right to demand OnCure (or its Successors and/or
Assigns) to purchase 150,000 shares of Common Stock (which such shares were
converted into Common Stock when

<PAGE>

CRC converted its Note) from it at a purchase price equal to $2.00 per share
plus interest at 10% percent per annum as set forth herein. The interest shall
accrue from December 30, 2000.

         2.1 CRC shall retain the right for a period of six (6) months from
December 1, 2001 through and including June 1, 2002 to sell the Common Stock to
OnCure (its Successors, representatives and/or Assigns) for a purchase price of
$2.00 per share plus 10% percent, interest on the sum of $300,000.00 from
December 30, 2000 (the "Put Right"). The Put Right shall expire on mid-night of
June 1, 2002.

         2.2 OnCure agrees that the Put Right of CRC is absolute and that OnCure
has no claim, defense, or off-set that or will in any way impede, restrict, or
prohibit CRC from exercising the Put Right in accordance with this Agreement.

         2.3 In the event that CRC desires to exercise its Put Right as set
forth in Section 2, it shall provide OnCure with written notice of its intent.

         2.4 OnCure shall remit payment by certified funds, bank check or wire
transfer and payment shall be received by CRC no later than five (5) days from
CRC's written notice to exercise its Put Right.

         2.5 In the event that CRC transfers, sells, assigns, hypothecates,
pledges or otherwise disposes the aforesaid Common Stock, the Put right shall
terminate. Notwithstanding this provision, in the event said stock is, however,
transferred, conveyed, sold, or distributed to any partner, whether general or
limited of CRC, then said Put Right shall inure to said transferred partner, who
shall have the same Put Right as CRC.

         2.6 CRC agrees that in the event it exercises its right to put the
Common Stock to OnCure all certificate(s) surrendered herein will be properly
endorsed and otherwise in proper form for transfer.

         2.7 In the event that any of the Common Stock Certificates are lost,
stolen or destroyed, OnCure's transfer agent or share registrar will, issue in
exchange for such loss, stolen or destroyed certificates, upon the making of an
Affidavit of that fact by CRC replacement certificate(s).

         2.8 The Parties hereto agree that the exercise price of the warrant to
acquire 60,000 shares that is the subject of this Agreement and which is being
exercised pursuant to this Agreement shall be reduced from $2.00 per share to
$.01 per share.

         2.9 OnCure agrees that the 150,000 shares of Common Stock have been
included in SB-2 Registration Statement that has been filed, but not declared
effective by the Commission. OnCure agrees that it will not take any action or
omit to act when required to do so that would cause these shares to be removed
from the registration statement.

         3. EXERCISE OF WARRANT. CRC hereby exercises its warrant to acquire
60,000 shares of Common Stock of OnCure at $.01 per share and hereby pays to
OnCure the sum of $600.00 as and in for consideration for the exercise of said
warrant, said sums to be deducted

securities" as defined by Rule 144 of the Securities Act of 1933, as amended.

         3.1 The Parties hereby stipulate and agree that the interest owed to
CRC at the rate of 10% percent per annum through June 22, 2001 is $13,701.30,
after deduction for payment of the consideration for the exercise of 60,000
warrants, which consideration is accepted by OnCure.

         3.2 The Parties further recognize and agree that interest will continue
to accrue from June 22, 2001 pursuant to this Agreement on the principal balance
of $300,000.00 at 10% percent per annum.

exercise by CRC its right to Put the Common Stock, it shall pay interest at the
highest legal rate permitted by law, said interest to be in addition to any
other sums due and owing to CRC herein.
