         the failure of any condition precedent under SECTION 6.2 hereof
         (unless the failure results primarily from SCN's breaching any
         representation, warranty, or covenant contained in this Agreement).

         VIII.2 Effect of Termination. If any Party terminates this Agreement
pursuant to SECTION 8.1 above, all rights and obligations of the Parties
hereunder shall terminate without any liability of any Party to any other Party
(except for any liability of any Party then in breach). Notwithstanding the
foregoing, in the event the transaction contemplated by this Agreement is not
consummated due to the fault of, or failure to perform hereunder by (i) OCOA or
the Physician Owners, then OCOA and the Physician Owners agree to reimburse SCN
for SCN's out-of-pocket expenses, including but not limited to professional
fees or (ii) SCN, then SCN agrees to reimburse OCOA and the Physician Owners
for their out-of-pocket expenses, including but not limited to professional

and assigns, officers and directors from or against any and all losses,
liabilities, claims, damages, actions, suits, costs, deficiencies, penalties,
and expenses (including without limitation reasonable attorney's fees)

of the breach, untruth or inaccuracy of any representation, warranty or
covenant of OCOA or the Physician Owners set forth in this Agreement, or (ii)

any indemnification rights granted to SCN under this Agreement, SCN shall
continue to be entitled to any indemnification under any prior agreements

jointly, shall be responsible for and shall pay to SCN the amount of OCOA's
unpaid indemnification obligations pursuant to this Agreement. Notwithstanding
the foregoing or anything contained in the Asset Purchase Agreement or the
Service Agreement, as herein defined, to the contrary, SCN acknowledges and

SCN agrees to give prompt notice to OCOA and the Physician Owners of the
assertion of any claim, or the commencement of any suit, action or proceeding,
in respect of which indemnity may be sought under SECTION 9.1. OCOA and the
Physician Owners may participate in and at their election, or at the request of
SCN, assume the defense of any such suit, action or proceeding at OCOA or the
Physician Owners' expense. Neither OCOA nor the Physician Owners shall be
liable under SECTION 9.1 for any settlement effected without their consent of
any claim, litigation or proceeding in respect of which indemnity may be sought
under SECTION 9.1, which consent shall not be unreasonably withheld.

         IX.3 General Indemnification by SCN. SCN agrees to and shall defend,

to which SCN is entitled to indemnification under this Agreement or any other
agreement).

to give prompt notice to SCN of the assertion of any claim, or the commencement
of any suit, action or proceeding in respect of which indemnity may be sought
under SECTION 9.3. SCN may participate in and at its election, or at the
request of the Physician Owners, assume the defense of any such suit, action or
proceeding at SCN's expense. SCN shall not be liable under SECTION 9.3 for any

shall not be unreasonably withheld.

         THIS BILL OF SALE is made and delivered by and from SPECIALTY CARE

         In connection therewith, for good and valuable consideration, the

and to more effectively consummate the transactions contemplated by the

as set forth in the Restructure Agreement. Seller represents and warrants that
the title conveyed is good and marketable, its transfer rightfully made; that
the Purchased Assets are delivered free and clear of all liens and
encumbrances; and that Seller will warrant and defend same against the lawful
claims and demands of all persons whomsoever.

         This instrument shall be binding upon Seller, its successors and
assigns, and shall inure to the benefit of Purchaser, its successors and
assigns. This instrument shall be effective as to the transfer of all of the
Purchased Assets as of the Closing Date.

         Nothing herein contained shall be deemed or construed as an assumption
by Purchaser of, or to impose upon Purchaser, any liabilities or obligations of
Seller, except as otherwise provided in that certain Assignment and Assumption
Agreement of even date herewith.

         This Bill of Sale shall be governed by and construed in accordance
with the laws of the State of New York.

                                    RELEASE


         THIS RELEASE is being executed and delivered in accordance with

contemplated by the Agreement, hereby agree as follows:

         OCOA and the Physician Owners on behalf of OCOA and themselves
individually and each of their Related Persons, hereby releases and forever
discharges SCN and each of its respective individual, joint or mutual, past,
present and future representatives, affiliates, stockholders, controlling

claims, demands, Proceedings, causes of action, Orders, obligations, contracts,
agreements, debts and liabilities whatsoever, whether known or unknown,
suspected or unsuspected, both at law and in equity, which each of OCOA and the

had or may hereafter have against the respective Releasees arising
contemporaneously with or prior to the Closing Date or on account of or arising

entered into prior to the date of the Agreement, and whether or not relating to
claims pending on, or asserted after, the Closing Date; provided, however, that
nothing contained herein shall operate to release any obligations of SCN
accruing after the Closing Date under the Agreement or the Management Services
Agreement, which are to remain in effect after Closing.

         OCOA and the Physician Owners hereby irrevocably covenants to refrain
from, directly or indirectly, asserting any claim or demand, or commencing,
instituting or causing to be commenced, any proceeding of any kind against any
Releasee, based upon any matter purported to be released hereby.

         Without in any way limiting any of the rights and remedies otherwise
available to any Releasee, each OCOA and the Physician Owners, jointly and
severally, shall indemnify and hold harmless each Releasee from and against all
loss, liability, claim, damage (including incidental and consequential damages)
or expense (including costs of investigation and defense and reasonable
attorney's fees) whether or not involving third party claims, arising directly
or indirectly from or in connection with (i) the assertion by or on behalf of
OCOA or the Physician Owners or any of their Related Persons of any claim or
other matter purported to be released pursuant to this Release, and (ii) the
assertion by any third party of any claim or demand against any Releasee which
claim or demand arises directly or indirectly from, or in connection with, any
assertion by or on behalf of OCOA or the Physician Owners or any of their
Related Persons against such third party of any claims or other matters
purported to be released pursuant to this Release.

         If any provision of this Release is held invalid or unenforceable by
any court of competent jurisdiction, the other provisions of this Release will
remain in full force and effect. Any provision of this Release held invalid or
unenforceable only in part or degree will remain in full force and effect to
the extent not held invalid or unenforceable.
