         THIS AGREEMENT (the "Agreement") is made and entered into as of this

Tennessee limited liability company, ("Landlord"), UROLOGY CENTER OF THE SOUTH,

State of Tennessee.

                                    RECITALS

         A.       Landlord has agreed to enter into a certain Lease Agreement
with UASC (the "ASC Lease"), attached hereto as EXHIBIT A, pursuant to which the
Landlord has agreed to lease to UASC the real property and improvements as set
forth and described in the ASC Lease (the "ASC Suite").

         B.       The obligations of UASC to Landlord are secured by liens on
and security interests in the collateral described in ARTICLE 16 of the ASC
Lease (the "ASC Lease Collateral").

         C.       Landlord has agreed to enter into a certain Lease Agreement
with UCS (the "Corporate Suite Lease"), attached hereto as EXHIBIT B, pursuant
to which the Landlord has agreed to lease to UCS the real property and
improvements as set forth and described in the Lease (the "Corporate Suite").

         D.       The obligations of UCS to Landlord are secured by liens on and
security interests in the collateral described in ARTICLE 16 of the Corporate
Suite Lease (the "Corporate Suite Lease Collateral").

         E.       Landlord has agreed to enter into a certain Lease Agreement
with UCS (the "Clinic Lease"), attached hereto as EXHIBIT C, pursuant to which
the Landlord has agreed to lease to UCS the real property and improvements as
set forth and described in the Lease (the "Clinic Suite").

         F.       The obligations of UCS to Landlord are secured by liens on and
security interests in the collateral described in ARTICLE 16 of the Clinic Lease
(the "Clinic Lease Collateral"). Collectively, the ASC Lease, the Corporate
Suite Lease, and the Clinic Lease are referred to herein as the "Leases".

         G.       To induce Landlord to enter into the ASC Lease, Ambulatory
Operations, Inc. ("AOI"), a Tennessee corporation, as a member of UASC executed
a Subordination Agreement (the "AOI Subordination Agreement") pursuant to which
AOI subordinated its rights to income and other distributions from UASC to the
obligations of UASC for payment and performance of UASC's obligations under the
ASC Lease.

         H.       To induce Landlord to enter into the ASC Lease, Methodist
Healthcare, a Tennessee not for profit corporation ("Methodist"), as owner of
AOI, executed a Limited Guaranty (the "Methodist Limited Guaranty") pursuant to
which Methodist agrees to transfer funds to AOI, in accordance with its
ownership percentage of UASC, to pay lease payments, subject to certain other
limitations as set forth in the Methodist Limited Guaranty.

         I.       To induce Landlord to enter into the ASC Lease, LeBonheur
Ambulatory Services, Inc., ("LeBonheur") a Tennessee corporation and an
affiliate of Methodist, who is the manager of UASC, has executed a Subordination
Agreement (the "LeBonheur Subordination Agreement") pursuant to which

                                       1

LeBonheur subordinated its rights to its Management Fee and certain other income
and distributions from UASC to the obligations of UASC for payment and
performance of UASC's obligations under the ASC Lease .

                  J.       To induce Landlord to enter into the ASC Lease, UCS,
as a member of UASC executed a Subordination, Limited Guaranty and
Indemnification Agreement pursuant to which UCS subordinated its rights to
income and other distributions from UASC to the obligations of UASC for payment
and performance of UASC's obligations under the ASC Lease (the "UCS
Subordination Agreement"). In addition, UCS guaranteed to the Landlord the
payment and performance of UASC's obligations under the ASC Lease pursuant to
the limited guaranty contained in the UCS Subordination Agreement.

                  K.       To induce Landlord to enter into the Leases, each of
the Physicians who are members of UCS have executed a Subordination,
Non-Compete, Limited Guaranty and Indemnification Agreement (the "Physician
Agreements").

                  L.       The Physician is a member holding ownership interests
in the income and profits and certain rights to distributions from UCS.

                  M.       The Physician is or will be practicing urology
services for UASC and is or may be entitled to payment of fees and other
distributions or payments from UASC.

                  N.       To induce Landlord to enter into the Leases, UCS,
UASC, and the Physician have executed this Agreement.

                  O.       The Landlord, UASC, UCS, and the Physician desire to
confirm as among themselves the rights and priorities with respect to certain
matters arising in connection with the Leases, the Subordinated Obligations and
Subordinated Claims (as defined herein), which are of mutual importance to them,
without otherwise affecting their respective rights under the other agreements,
instruments, and other writings executed and delivered in connection therewith,
all as more fully set forth herein.

                  P.       Further, to induce Landlord to enter into the Leases,
the Physician has agreed to enter into the Non-Compete, Indemnification, and
Guaranty obligations as set forth herein.

                  Now Therefore, in consideration of the premises and in
consideration of the execution and delivery of the Leases, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, UCS, UASC and the Physician, for themselves and for each other
present and future holder of any Subordinated Obligation or Subordinated Claim,
intending to be legally bound, hereby agree for the direct and legally
enforceable benefit of Landlord, each other Landlord and each other present and

                  UASC, UCS and the Physician hereby covenant and agree that the
Subordinated Obligations and Subordinated Claims are and shall be postponed,
subordinated and junior in right of payment and performance to the prior payment
in full in cash and the performance of all Lease Obligations and Lease Claims,
on the terms and conditions herein set forth.

SECTION 3.2       PRIORITIES REGARDING LEASE COLLATERAL.

                  Notwithstanding anything to the contrary contained in or
arising from the Leases or the Collateral Agreements, or any other note,
agreement, lease, employee agreement, management agreement, instrument, or
document now or hereafter executed and delivered by the Landlord, UASC, UCS, the
Physician, or any party to the Collateral Agreements, or any instrument or
document executed and delivered in connection therewith, or otherwise including
any extensions, renewals or forbearances thereof, any prior perfection of a
security interest, mortgage, deed of trust, lien, or the provisions of the
Uniform Commercial Code, or other law of any jurisdiction which is applicable,
or the existence of any present or future filing of financing statements under
the Uniform Commercial Code, or other law of any jurisdiction which is
applicable, or other filings or recordings under any other law of any
jurisdiction which is applicable or in which such filing or recording has been
made, the priorities of the liens and security interests of the Landlord in the
Lease Collateral (including proceeds of casualty and title insurance) securing
the Lease Obligations and Lease Claims, shall be senior and prior to any liens
and security interest of the Physician at any time obtained on such collateral,
and the liens and security interests of Physician at any time obtained in such
Lease Collateral shall be junior liens and security interests subject to the
liens and security interests of the Landlord.

SECTION 3.3       ASSIGNMENT OF COLLATERAL.

                  Upon payment or other satisfaction in full of all obligations
secured by any collateral now or hereafter in the possession of any party
hereto, the then holder thereof will assign and deliver to the other parties
hereto holding a security interest in such collateral, as directed in writing by
such other parties, without representation, warranty, or recourse of any kind,
all such collateral then in the possession of such holder, and

                                       6
<PAGE>

in so doing, such holder shall thereupon be discharged from further
responsibility with respect thereto. So long as any obligations secured by any
collateral remain unpaid to the holder of such collateral, including, without
limitation, a holder to which any such obligations shall have been assigned,
such holder may, subject to the provisions of this Agreement, at all times in
its sole discretion exercise any and all powers and rights which it now has or
may hereafter acquire with respect thereto, without the necessity of obtaining
any approval of any of the other parties hereto; nor shall such holder of any
collateral have any liability for any action taken or failure to act with
respect to any of such collateral held by it beyond the exercise of reasonable
care to assure the safe custody thereof.

                              ARTICLE 4. PAYMENTS

SECTION 4.1       PHYSICIAN AS TRUSTEE.

                  If Physician shall receive any payment or distribution out of
any of the assets of UASC or UCS, whether or not arising out of or as a result
of any event described in SECTION 4.2 or any action or right of remedy exercised
pursuant to SECTION 5.2.2 of this Agreement, and such payment or distribution or
the retention thereof by the Physician is not in accordance with the provisions
of this Agreement, then Physician shall hold such payment or distribution in
trust as trustee of an express trust, for the benefit of the Landlord, shall not
commingle such payment or distribution with its other assets, and shall promptly
take all action necessary to cause such payment or distribution to be allocated
or paid in accordance with this Agreement.

SECTION 4.2       PERMISSIBLE PAYMENTS OF SUBORDINATED CLAIMS.

                  For as long as the Leases are in effect and thereafter until
all Lease Obligations and Lease Claims have been paid in full in cash and/or
otherwise performed and discharged, UASC and UCS will not make or permit to be
made, and the Physician will not demand, accept, receive or retain, any payment
or distribution of any kind or character, whether in cash, property, securities
or otherwise, on account or in respect of any Subordinated Obligation or
Subordinated Claim, except that:

                  4.2.1    Any payments of regularly scheduled installments or
         any other payments required under the Subordinated Obligations, may be
         paid if (and only if) at the time of such payment no Rent is due and
         payable to Landlord and all Lease Obligations and Lease Claims then
         currently due and owing have been paid in full in cash by UASC and UCS,
         as Tenants respectively, or if such Lease Obligations and Lease Claims
         do not require the payment of cash, such Obligations and Claims have
         been discharged by UASC and UCS, as Tenants respectively, as
         applicable, and no Default Notice (as herein defined) has been received
         by UASC and UCS or the Physician. Any payments made to Physician that
         do not meet the requirements of the first sentence of this paragraph
         shall be held by Physician in trust for the benefit of Landlord and
         promptly forwarded to Landlord for application to the Lease Obligations
         and Lease Claims.

                  4.2.2    No such payment may be made at any time when any
         Bankruptcy, Insolvency, or Liquidation Proceeding against UCS, UASC or
         any party to the Collateral Agreements is pending. No such payment
         shall be made that renders UASC or UCS insolvent or unable to meet its
         Lease Obligations or pay the Lease Claims in cash as they become due.

SECTION 4.3       PREPAYMENTS TO PHYSICIAN.

                  Physician will give Landlord written notice of (a) any
prepayment of a regularly scheduled payment; or, (b) receipt of any payment or
distribution of any kind or character, whether in cash, property, securities or
otherwise made by UASC or UCS, respectively, in violation of SECTION 4.2, on the
Subordinated Obligations or Subordinated Claims or otherwise to Physician, on
the Subordinated Obligations or Subordinated Claims or otherwise to Physician,
and, within twenty (20) Business Days after such notice is given, Landlord will
notify Physician as to whether such prepayment will be held by Physician in
trust for the benefit of Landlord and promptly forwarded to Landlord for
application to the Lease Obligations and Lease

                                       7
<PAGE>

Claims. If Landlord fails to notify Physician that such prepayment is to be held
in trust by the Physician and forwarded to the Landlord as set for in the
preceding sentence, within such twenty (20) Business Day period, then such
prepayment shall be deemed to be a permitted payment, and shall be retained by
Physician for its own account.

SECTION 4.4       INSURANCE PROCEEDS.

                  With respect to the collection of any proceeds of any policy
of insurance covering any collateral, or any part thereof, the proceeds of which
are assigned to Landlord and/or Physician as additional collateral to secure the
obligations of UASC and UCS, as Tenants respectively, under the Lease
Obligations or the Subordinated Obligations, the Landlord and Physician shall
join in any instructions to the insurance companies involved so that the
proceeds of such insurance shall be payable in full to Landlord and then, to the
extent of any excess, to Physician or any of the parties to the Collateral
Agreements as their interest may appear.

                               ARTICLE 5. DEFAULT

SECTION 5.1       DEFAULT NOTICE AND PAYMENT BLOCKAGE.

                  Upon the occurrence and continuance of any Event of Default
(under and as defined in the Leases, or the Collateral Agreements or this
Agreement), and upon a declaration of an Event of Default by the Landlord with
written notice specifying the nature thereof (the "Default Notice") to the
Physician, then unless and until said Event of Default shall be cured or waived
to the sole satisfaction of the Landlord, with written notice of such waiver or
cure to be given to the Physician, (a) Landlord shall be entitled to thereafter
receive payment and performance in full of all Lease Obligations and Lease
Claims before Physician shall be entitled to receive any payment upon the
Subordinated Obligations or otherwise, and (b) after all Lease Obligations have
been paid in full and performed and discharged in full, Physician shall be
entitled to receive full payment on the Subordinated Obligations.

SECTION 5.2       ACCELERATION AND ENFORCEMENT OF SUBORDINATED CLAIMS.

                  Until all Lease Obligations and Lease Claims have been
discharged, performed and paid in full in cash, the Physician will not (a)
demand, accelerate, bring suit to collect or otherwise exercise or enforce any
right or remedy in respect of any Subordinated Claim or commence or prosecute
any action or proceeding thereon, (b) commence any Bankruptcy, Insolvency or
Liquidation Proceeding or join with any creditor in commencing any Bankruptcy,
Insolvency or Liquidation Proceeding, or appear in any Bankruptcy, Insolvency or
Liquidation Proceeding commenced by any other creditor in support of the
commencement or continuation thereof, or (c) otherwise exercise or enforce any
right or remedy in respect of any Subordinated Claim, including any right or
remedy that otherwise might be available to it in any Bankruptcy, Insolvency or
Liquidation Proceeding, unless:

                  5.2.1    The Landlord has received written notice thereof,
         stating the action to be taken and the grounds therefor, and at least
         180 days have elapsed since the date such written notice was received

                  5.2.2    Notwithstanding the foregoing, nothing in this
         SECTION 5.2.2 shall limit the rights of the Physician to prove and
         establish its Subordinated Claims in any such Bankruptcy, Insolvency,
         or Liquidation Proceeding.

                  6.1.1    All Lease Claims (including all Post-Petition Claims)
         shall be discharged, performed and paid in full in cash before the

         Lease Claims shall be entitled to receive each payment and distribution

         Insolvency, or Liquidation Proceeding directly to the Landlord for the
         benefit of such holders of Lease Claims.

                  Except as otherwise agreed in writing by the Landlord, no

SECTION 6.3       DISCHARGE OF PHYSICIAN.

                  No discharge of the liability of the debtor in such
Bankruptcy, Insolvency or Liquidation Proceeding shall, as against the

Subordinated Claims and to apply such payment or distribution to pay the Lease
Claims (including all Post-Petition Claims accrued or incurred through the date
on which cash proceeds have been received by the holders of Lease Claims in an

liens upon any Lease Collateral or (c) seek, or join with any creditor or the
debtor or any trustee or representative in seeking, substantive consolidation of
the

                                       9

                  The Physician shall file, in appropriate form, all claims, and
proofs of claim in respect of such Subordinated Claims whenever the filing of
claims is required or permitted by law upon any of the Subordinated Claims. If
the Physician does not file any such claim or proof of claim promptly upon the
request of Landlord, then the Landlord, and its agents, is hereby irrevocably
authorized and empowered (but shall not be obligated), as attorney-in-fact for
the Physician with full power of substitution, either to file such claim or
proof thereof in the name of the Physician or, at the option of Landlord, to

other action or proceeding, subject to the prior performance and payment in full
and in cash of any and all Lease Obligations and Lease Claims (including all
Post-Petition Claims), the Physician shall have and may enforce any and all
rights of subrogation accorded by law in respect of any payment or distribution
on account of any Subordinated Claim that is applied to the payment of any Lease
Claim pursuant to the provisions of this Agreement. For such purposes:

                  6.7.1    No right of subrogation shall be available to or may
         be enforced by the Physician, unless and until all Lease Claims
         (including all Post-Petition Claims) have been performed and discharged
         in full and paid in full in cash.

                  6.7.2    No holder of any Lease Obligations or Lease Claim
         makes any representation or warranty, or shall otherwise have any
         responsibility, as to whether any such right of subrogation is accorded
         or available to the Physician or is enforceable by the Physician in any
         particular circumstance.

                  6.7.3    No holder of any Lease Obligation or Lease Claim
         shall have any duty to the Physician to ensure, perfect, protect,
         enforce or maintain any right of subrogation that might otherwise be
         accorded or available to or enforceable by the Physician. The
         subordination provided herein and the rights of the holders of Lease
         Claims hereunder shall remain fully enforceable on the terms set forth
         herein, regardless of any act, omission or circumstance (whether or not
         attributable to any holder of any Lease Claim and whether or not
         wrongful) which does or might in any manner or in any respect destroy,
         limit, reduce, affect or impair any right of subrogation otherwise
         accorded or available to or enforceable by the Physician. Each holder
         of any Lease Obligations or Lease Claim shall remain utterly free to
         take or fail to take any and all actions in respect of any Lease
         Obligation or Lease Claim or any person or entity liable therefor or
         any collateral security therefor (including each and all of the acts,
         omissions and matters described in SECTION 7.2), without exonerating
         the Physician, even if any right of subrogation is destroyed, limited,
         reduced, affected or impaired thereby.

                  6.7.4    The subordination provided herein and the rights of
         the holders of Lease Obligations

                                       10
<PAGE>

         and Lease Claims hereunder shall be fully enforceable as to all Lease
         Obligations and Lease Claims which are not allowed, allowable or
         enforceable in such Bankruptcy, Insolvency or Liquidation Proceeding
         (including Post-Petition Claims), even if and even though no right of
         subrogation is available in respect of such Lease Obligations and Lease
         Claims.

                  6.7.5    For purposes of enforcing any right of subrogation on
         the terms set forth in this SECTION 6.7, no payment or distribution on
         account of any Subordinated Claim applied to the performance, discharge
         or payment of a Lease Obligation or Lease Claim shall, as between the
         UASC and UCS, respectively and the Physician and to the extent of the
         payment or distribution so applied, discharge the liability of UASC and
         UCS, as Tenants respectively for the payment of such Lease Obligation
         and Lease Claim and, to this end, UASC and UCS, as Tenants respectively
         shall remain obligated to pay such Lease Obligation and Lease Claim in
         full despite any such application.

                     ARTICLE 7. IMPAIRMENT OF SUBORDINATION

SECTION 7.1       SUBORDINATION NOT PREJUDICED, AFFECTED OR IMPAIRED.

                  No right of any present or future holder of any Lease
Obligation and Lease Claim to enforce subordination as provided in this
Agreement shall at any time in any way be prejudiced, affected or impaired by
any act or failure to act on the part of UASC, UCS or any party to the
Collateral Agreements or by any act or failure to act on the part of the
Landlord or any holder of Lease Obligations and Lease Claims or by any breach or
default by UASC and UCS, in the performance or observance of any promise,
covenant or obligation enforceable by the Landlord or the Physician, regardless
of any knowledge thereof that any holder of Lease Claims may have or otherwise
be charged with.

SECTION 7.2       ACTIONS BY LANDLORD.

                  Without in any way limiting the generality of the foregoing,
the Landlord and each holder of any Lease Obligations or Lease Claim may at any
time and from time to time, without the consent of or notice to the Physician,
without incurring any responsibility or liability to the Physician and without

                   ARTICLE 9. LEASE DEFAULT AND ACCELERATION

SECTION 9.1       RIGHT TO CURE.

                  When Landlord gives Physician, as provided in ARTICLE 5
hereof, a Default Notice, Physician shall have the right, but not the
obligation, to undertake to cure such an Event of Default. If Physician
determines to undertake to cure such Event of Default, he will so notify
Landlord within three (3) Business Days after receipt of Landlord's notice, or
he will be deemed to have waived this right. Landlord may exercise any and all
remedies available to it consistent with the provisions of this Agreement while
Physician is considering whether to cure such Event of Default. If Physician
elects to cure such Event of Default, Physician must cure within ten (10)
Business Days of the receipt of such notice such Event of Default as it exists
on the date of cure and not on the date of the Default Notice delivered to
Physician; provided, however, Physician shall have no obligation to then cure
any other Event of Default not stated in the Default Notice.

SECTION 9.2       ACCELERATION NOTICE.

                  Upon any acceleration of the Lease Obligations, a written
notice of acceleration (the "Acceleration Notice") shall be given by the
Landlord to Physician within fifteen (15) Business Days (a Business Day for the
purposes of this Agreement being a day that satisfies the definition of Business
Day in the applicable Lease) of such acceleration. Under certain circumstances
specified in such Lease, the Landlord may be entitled to send out Default
Notices and Acceleration Notices simultaneously, and the Physician hereby
acknowledges this right.

SECTION 9.3       OWNERSHIP OF SUBORDINATED OBLIGATIONS.

                  Physician warrants and represents that he has not previously
assigned any interest in the Subordinated Obligations or Subordinated Claims and

OR ENTITY WHICH UASC OR UCS ALLOWS TO PERFORM MEDICAL SERVICES AND PHYSICIAN

FOREGOING RESTRICTIONS, THEN UASC AND UCS NOTWITHSTANDING ANY OTHER PROVISION OF

LEASE WHERE SUCH SERVICES ARE PERFORMED AND PHYSICIAN SHALL BE IN DEFAULT OF
THIS AGREEMENT. UASC and UCS SHALL (AND PHYSICIAN SHALL CAUSE UASC and UCS) TO
IMMEDIATELY CEASE AND DESIST SUCH VIOLATION AND/OR CAUSE ANY PERSON OR ENTITY
CAUSING SUCH VIOLATION TO IMMEDIATELY AND PERMANENTLY VACATE THE SUITE.

                  WITHOUT LIMITING ANY OTHER RIGHTS THAT LANDLORD MAY HAVE UNDER
THE LEASE, INCLUDING LANDLORD'S RIGHT OF TERMINATION, LANDLORD SHALL BE ENTITLED
TO EXERCISE ANY AND ALL REMEDIES, AT LAW OR IN EQUITY, TO ENFORCE THE FOREGOING

ACCORDINGLY, LANDLORD SHALL BE ENTITLED TO INJUNCTIVE RELIEF (TEMPORARY AND
PERMANENT) AND/OR SPECIFIC PERFORMANCE, OR OTHER APPROPRIATE EQUITABLE REMEDY,

holder of a Subordinated Obligation or Subordinated Claim and their respective
successors and assigns with respect to any and all claims, demands, actions,

without limitation, reasonable attorney's fees, consultant's fees and court
costs) of any and every kind or character, known or unknown, fixed or
contingent, asserted against or incurred by any Indemnified Party at any time
and from time to time by reason or arising out of any breach or violation of
ARTICLE 10 of this Agreement by UASC, UCS or Physician, their affiliates,
successors and assigns.

                          ARTICLE 11. LIMITED GUARANTY

SECTION 11.1      GUARANTY OF MEMBER.

                  Physician, as Guarantor, as additional consideration for the
execution of the Leases by Landlord, hereby irrevocably, unconditionally and
absolutely becomes guarantor of the prompt and faithful performance by UASC,
UCS, respectively of all of the terms, covenants, conditions, agreements and
provisions to be kept, observed and performed by UASC and UCS under the
respective Leases, including without limitation, the payment by UASC, UCS,
respectively, of the Rent (as defined in the Leases) and any and all other sum
or sums to become due thereunder, and hereby further agrees as follows:

                  11.1.1   Guarantor agrees that (a) this obligation shall be
         binding upon Guarantor without any further notice or acceptance hereof;
         (b) immediately upon receipt of notice by Guarantor of the

                                       15
<PAGE>

         occurrence of a Default (as such term is defined in the Lease or under
         this Agreement or the Collateral Agreements), Guarantor will pay to
         Landlord the Rent and will keep, observe and perform all the terms,
         covenants, conditions, agreements and provisions of the Lease which are
         to be kept, observed and performed by Tenant under the Leases; (c) no
         extension, forbearance or leniency extended by Landlord to either UASC
         or UCS shall discharge Guarantor and Guarantor agrees that it will
         remain liable hereunder at all times; (d) Landlord and UASC and UCS,
         respectively, may at any time or times enter into such modifications,
         extensions, amendments or other covenants respecting the Lease, and
         Guarantor shall not be released thereby, and Guarantor shall then
         continue as guarantor with respect to the Lease as so modified,
         extended, amended or otherwise affected, provided Guarantor has
         consented to any and all such modifications, extensions or amendments;
         (e) neither Guarantor's obligation to make payment in accordance with
         the provisions of this Guaranty nor any remedy for the enforcement
         thereof shall be impaired, modified, changed, released or limited in
         any manner whatsoever by any impairment, modification, change, release
         of limitation of the liability of UASC, UCS or their respective estates
         in bankruptcy arising from the operation of any present or future
         provision of the Federal Bankruptcy Code or any other law of the United
         States or of any state relating to bankruptcy, insolvency,
         reorganization, readjustment, receivership or similar proceeding of any
         nature whatsoever, or the disaffirmance of the Leases in any such
         proceedings or otherwise; and (f) Guarantor shall continue as guarantor
         with respect to the Leases upon any assignment and/or subletting by
         UASC or UCS of any or all of their respective interests, in, to and
         under the Leases or the Leased Space, whether or not Guarantor has
         received notice of or consent to any and all such assignments and/or
         sublettings.

                  11.1.2   Guarantor further agrees to be bound by each and
         every term, covenant, condition, agreement, and provision of the
         Leases, with the same force and effect as if it were designated in and
         had executed the Leases as tenant thereunder. Guarantor hereby
         acknowledges receipt and acceptance of a copy of the Leases.

                  11.1.3   This as an agreement of both guaranty and suretyship.
         The liability of Guarantor shall be direct and may be enforced without
         Landlord's being required to resort to any other right, remedy, or
         security, or to proceed against any other party. Landlord may proceed
         against UASC, UCS, Guarantor, or other parties in such order as
         Landlord may elect without waiving its right to proceed singly,
         successively, or cumulatively against Guarantor or any other party.

                  11.1.4   Guarantor may, at Landlord's option, be joined in any
         action or proceeding commenced by Landlord against UASC or UCS, in
         connection with and based upon any terms, covenants, conditions,
         agreements or provisions of the Lease. Guarantor waives any demand by
         Landlord or prior action by Landlord of any nature whatsoever against
         UASC or UCS, including without limitation, any right which Guarantor
         might otherwise have, under any statute or rule of law, to require
         Landlord to take any action against UASC and UCS prior to proceeding
         against Guarantor hereunder.

                  11.1.5   Guarantor hereby acknowledges that the rights,
         benefits and privileges hereunder shall inure to the benefit of each
         and every assignee of Landlord and of Landlord's interest in, to and
         under the Lease, and that Guarantor shall continue to be bound
         hereunder upon such assignment without further documentation.

                                    Percentage Ownership Interest of all Lease
                                    Obligations and Lease Claims which are not
                                    performed, discharged or paid in full by UCS
                                    under the Corporate Suite Lease.

                           11.2.3.3 Upon Physician's payment to Landlord or any
                                    holder of the Lease Obligations and Lease

                                    under the Clinic Suite Lease.

                           11.2.3.4 Provided, however, that the aggregate amount
                                    payable by Physician under this SECTION
                                    11.2.3 shall not exceed in the aggregate

         decreased ownership interest execute and deliver a subordination,
         non-compete and limited Guaranty agreement substantially identical with
         this Agreement.

                  11.2.5   Provided, however that the limitations on Guarantor's

                       ARTICLE 12. NON-COMPETE PROVISIONS

SECTION 12.1      NON-COMPETE AGREEMENT.

                  As additional consideration for Landlord to enter into the
Leases, Physician acknowledges and agrees that for a period of twenty four (24)
months from and after the date of termination of the Physician's employment for
any reason with UCS, the Physician shall not, directly or indirectly, alone or
as a member of a partnership, association or joint venture, or as an officer,
director, stockholder, consultant, or employee of any entity, or in any other
capacity, engage in the practice of furnishing urology services within five (5)
miles of the Project. The provisions of this Section shall not preclude the
Physician from serving on the Medical Staff of Baptist East Hospital, St.
Francis Hospital or Methodist-Germantown Hospital and perform urology services
as a member of the Medical Staff in such hospitals.

                           ARTICLE 13. MISCELLANEOUS

SECTION 13.1      SPECIFIC ENFORCEMENT.

                  UASC, UCS and the Physician acknowledge and agree that an
action for money damages is not an adequate remedy for enforcement of this
Agreement and, accordingly, agree that each and all of the obligations arising
hereunder may, at the option of the Landlord, be enforced by an action for
specific performance or other lawful specific or injunctive relief.

SECTION 13.2      POWERS AND AUTHORITIES IRREVOCABLE; NO DUTY.

                  All rights, powers and authorities herein granted to the
Landlord are coupled with an interest and are irrevocable until Discharge of the
Lease Obligations and Lease Claims and all outstanding Lease Obligations or
Lease Claims have been performed, discharged and paid in full in cash. Such
rights, powers and authorities may be freely exercised by Landlord, or not
exercised by it, in each instance as it may see fit given its own individual
interest as a holder of a Lease Obligation or Lease Claim, without any duty of
care, duty of loyalty or other duty whatsoever to the Physician.

SECTION 13.3      ENFORCEABILITY.

                  This Agreement (a) shall be binding upon and enforceable
against UASC, UCS and their respective successors and assigns and the Physician
and each and all of his successors and assigns whether such holder of a
Subordinated Obligation or Subordinated Claims holds such Subordinated Claim or
Subordinated Obligation as a lien holder, secured party or otherwise, (b) may be
jointly or separately enforced in any lawful manner against any one or more or
all of the persons and entities bound hereby, without any requirement that other
Claims or persons or entities bound hereby be joined (and no single or partial
exercise or enforcement of any right hereunder shall preclude any other or
further exercise or enforcement thereof), and (c) shall inure to the benefit of
and be enforceable by Landlord, its successors and assigns and transferees and
each other present and future holder of any Lease Obligation or Lease Claim.
Without limiting the foregoing, Landlord shall have the right to assign this
Agreement to any Lender of Landlord with respect to the Leases and the Physician
hereby agrees to provide such estoppel certificates to such Lender as may be
required and necessary with respect to the right of the Lender to the benefits
of this Agreement.

SECTION 13.4      COMPLETE AGREEMENT; INCONSISTENCY; MODIFICATION; WAIVER.

                  This Agreement, the Leases, and the Collateral Agreements set
forth definitely and exhaustively the complete agreement of the parties with
respect to the subject matter hereof. No provision hereof and no right arising
hereunder may be modified or waived by any oral agreement or shall be deemed to
have been modified or waived by any act or failure to act or shall otherwise be
affected or changed, except as and to the extent expressly set forth in a
writing signed by the party to be bound thereby.

SECTION 13.6      GOVERNING LAW; CONSENT TO JURISDICTION.

                  This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Tennessee. Each of UASC, UCS and the
Physician hereby (a) irrevocably consents to the exclusive jurisdiction of the
courts of the County of Davidson in the State of Tennessee or the courts of the
United States for the Middle District of Tennessee in respect of any action or
proceeding arising out of or in connection with this Agreement or for the
enforcement of any right hereunder, (b) waives any objection which it may have
at any time to the laying of venue of any such action or proceeding in any such
court, waives any claim that such action or proceeding has been brought in an
inconvenient forum, and further waives the right to object that such court does
not have jurisdiction over such party, and (c) agrees that process in any such
action or proceeding may be served upon it, and shall be sufficiently served
upon it, by mail to its address set out on the signature pages hereof; without
limiting the right of any person or entity to serve process in any other manner
permitted by law.

SECTION 13.7      WAIVER OF RIGHT TO TRIAL BY JURY.

                  Each party hereto hereby waives, absolutely, unconditionally,
irrevocably and forever, any right to trial by jury in any action or proceeding
arising out of or in connection with this Agreement or for the enforcement of
any right hereunder.

enforceable against each signatory party hereto by Landlord and each other

acceptance hereof by Landlord or any such holder is hereby waived, and reliance
hereon by each of them is hereby unconditionally and conclusively acknowledged.

SECTION 13.9      COUNTERPARTS.

                                    AGREEMENT

         THIS AGREEMENT (the "Agreement") is made and entered into as of this
26TH DAY OF JUNE, 2001 by, between and among BRIERBROOK PARTNERS, LLC, a
Tennessee limited liability company, ("Landlord"), LEBONHEUR AMBULATORY
SERVICES, INC., a Tennessee corporation, ("LeBonheur"), and UROLOGY AMBULATORY
SURGERY CENTER, L.L.C., a Tennessee limited liability company ("UASC").

                                    RECITALS

         A.       Landlord has agreed to enter into a certain Lease Agreement
with UASC (the "ASC Lease"), attached hereto as EXHIBIT A, pursuant to which the
Landlord has agreed to lease to UASC the real property and improvements as set
forth and described in the ASC Lease (the "ASC Suite").

         B.       The obligations of UASC to Landlord are secured by liens on
and security interests in the collateral described in ARTICLE 16 of the ASC
Lease (the "ASC Lease Collateral").

         C.       LeBonheur has entered into a Management Agreement with UASC
(the "Management Agreement") attached hereto as EXHIBIT B.

         D.       To induce Landlord to enter into the ASC Lease, LeBonheur and
UASC have executed this Agreement.

         E.       The Landlord, UASC and LeBonheur, desire to confirm as among
themselves the rights and priorities with respect to certain matters arising in
connection with the ASC Lease and the Subordinated Obligations and Subordinated
Claims (as defined herein), which are of mutual importance to them, without
otherwise affecting their respective rights under the ASC Lease or under the
other agreements, instruments, and other writings executed and delivered in
connection therewith, all as more fully set forth herein.

         Now Therefore, in consideration of the premises and in consideration of
the execution and delivery of the Lease, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
LeBonheur and UASC, for themselves and for each other present and future holder
of any Subordinated Obligation or Subordinated Claim, intending to be legally
bound, hereby agree for the direct and legally enforceable benefit of Landlord,
each other Landlord and each other present and future holder of any Lease
Obligation or Lease Claim as follows:

         ALL AS DEFINED IN SECTION 5.1) TO LEBONHEUR; AND,

                  1.1.3    AT THE TIME OF SUCH PAYMENT, THERE IS NO BANKRUPTCY,

                              ARTICLE 4. PAYMENTS

SECTION 4.1       LEBONHEUR AS TRUSTEE.

                  If LeBonheur shall receive any payment or distribution out of
any of the assets of UASC, whether or not arising out of or as a result of any
event described in SECTION 4.2 or any action or right of remedy exercised
pursuant to SECTION 5.2.2 of this Agreement, and such payment or distribution or
the retention thereof by LeBonheur is not in accordance with the provisions of
this Agreement, then LeBonheur shall hold such payment or distribution in trust
as trustee of an express trust, for the benefit of the Landlord, shall not
commingle such payment or distribution with its other assets, and shall promptly
take all action necessary to cause such payment or distribution to be allocated
or paid in accordance with this Agreement.

SECTION 4.2       PERMISSIBLE PAYMENTS OF SUBORDINATED CLAIMS.

                  For as long as the Leases are in effect and thereafter until
all Lease Obligations and Lease Claims have been paid in full in cash and/or
otherwise performed and discharged, UASC will not make or permit to be made, and
LeBonheur will not demand, accept, receive or retain, any payment or
distribution of any kind or character, whether in cash, property, securities or
otherwise, on account or in respect of any Subordinated Obligation or
Subordinated Claim, except that:

                  4.2.1    Any payments of regularly scheduled installments or
         any other payments required under the Subordinated Obligations, may be
         paid if (and only if) at the time of such payment no Rent is due and
         payable to Landlord and all Lease Obligations and Lease Claims then
         currently due and owing have been paid in full in cash by UASC. Any
         payments made to LeBonheur that do not meet the requirements of the
         first sentence of this paragraph shall be held by LeBonheur in trust
         for the benefit of Landlord and promptly forwarded to Landlord for
         application to the Lease Obligations and Lease Claims.

                  4.2.2    No such payment of a Subordinated Obligation or
         Subordinated Claim may be made at any time when any Bankruptcy,
         Insolvency, or Liquidation Proceeding against UASC is pending. No such
         payment of a Subordinated Obligation or Subordinated Claim shall be
         made that renders UASC insolvent or unable to meet its Lease
         Obligations or pay the Lease Claims in cash as they become due.

SECTION 4.3       PREPAYMENTS TO LEBONHEUR.

                  LeBonheur will give Landlord written notice of (a) any
prepayment of a regularly scheduled payment; or, (b) receipt of any payment or
distribution of any kind or character, whether in cash, property, securities or
otherwise made by UASC, in violation of SECTION 4.2, on the Subordinated
Obligations or Subordinated Claims or otherwise to LeBonheur and, within twenty
(20) Business Days after such notice is given, Landlord will notify LeBonheur as
to whether such prepayment will be held by LeBonheur in trust for the benefit of
Landlord and promptly forwarded to Landlord for application to the Lease
Obligations and Lease Claims. If Landlord fails to notify LeBonheur that such
prepayment is to be held in trust by LeBonheur and forwarded to the Landlord as
set for in the preceding sentence, within such twenty (20) Business Day period,
then such prepayment shall be deemed to be a permitted payment, and shall be
retained by LeBonheur for its own account.

                               ARTICLE 5. DEFAULT

SECTION 5.1       DEFAULT NOTICE AND PAYMENT BLOCKAGE.

                  Upon the occurrence and continuance of an Event of Default for
the failure to pay Rent (under

                                       4
<PAGE>

in SECTION 2.1.5 of this Agreement), and upon a declaration of an Event of
Default by the Landlord for the failure to pay Rent or by LeBonheur under this
Agreement with written notice specifying the nature thereof (the "Default
Notice") to LeBonheur, then unless and until said Event of Default for the
failure to pay Rent or by LeBonheur, as applicable, shall be cured or waived to
the reasonable satisfaction of the Landlord, with written notice of such waiver
or cure to be given to LeBonheur, (a) Landlord shall be entitled to thereafter
receive payment in full of all Rent before LeBonheur shall be entitled to
receive any payment upon the Subordinated Obligations, and (b) after all Rent
has been paid in full and discharged in full, LeBonheur shall be entitled to
receive full payment on the Subordinated Obligations.

SECTION 5.2       ACCELERATION AND ENFORCEMENT OF SUBORDINATED CLAIMS.

                  Until all Rent has been paid in full in cash, LeBonheur will
not (a) demand, accelerate, bring suit to collect or otherwise exercise or
enforce any right or remedy in respect of any Subordinated Claim or commence or
prosecute any action or proceeding thereon, (b) commence any Bankruptcy,
Insolvency or Liquidation Proceeding or join with any creditor in commencing any
Bankruptcy, Insolvency or Liquidation Proceeding, or appear in any Bankruptcy,
Insolvency or Liquidation Proceeding commenced by any other creditor in support
of the commencement or continuation thereof, or (c) otherwise exercise or
enforce any right or remedy in respect of any Subordinated Claim, including any
right or remedy that otherwise might be available to it in any Bankruptcy,
Insolvency or Liquidation Proceeding, unless:

                  5.2.1    The Landlord has received written notice thereof,
         stating the action to be taken and the grounds therefor, and at least
         180 days have elapsed since the date such written notice was received
         by the Landlord.

                  5.2.2    Notwithstanding the foregoing, nothing in this
         SECTION 5.2 shall limit the rights of LeBonheur to prove and establish
         its Subordinated Claims in any such Bankruptcy, Insolvency, or
         Liquidation Proceeding.

proceedings in connection therewith, relative to UASC, or to its property, and
in the event of any proceedings for voluntary liquidation, dissolution, or other
winding up of UASC, whether or not involving insolvency or bankruptcy:

                  6.1.1    All Lease Claims (including all Post-Petition Claims)
         shall be discharged, performed and paid in full in cash before
         LeBonheur shall be entitled to receive any payment, performance or
         distribution of any kind or character, whether in cash, property,
         securities or otherwise, on account or in respect of any Subordinated
         Claim in such Bankruptcy, Insolvency or Liquidation Proceeding.

                  6.1.2    The holders of Lease Claims after discharge of the
         Lease Claims shall be entitled to receive each payment and distribution
         of any kind or character, whether in cash, property, securities or
         otherwise (including any such payment or distribution which may become
         payable or deliverable by reason of any other Claim being subordinated
         to any Subordinated Claim), that may become payable or deliverable on
         account or in respect of any Subordinated Claim, for application to the

shall be deemed applied to the payment of Lease Claims at any adjudicated or
imputed value.

SECTION 6.3       DISCHARGE OF LEBONHEUR.

                  No discharge of the liability of the debtor in such
Bankruptcy, Insolvency or Liquidation Proceeding shall, as against LeBonheur as
a creditor, constitute performance and/or payment of the Lease Claims or shall
in any respect affect or impair the right of the holders of Lease Claims to
receive each performance, payment or distribution on account or in respect of
Subordinated Claims and to apply such payment or distribution to pay the Lease
Claims (including all Post-Petition Claims accrued or incurred through the date
on which cash proceeds have been received by the holders of Lease Claims in an
amount sufficient to pay all Lease Claims in full), until cash proceeds have
been received and applied to the payment of and performance of Lease Claims in
an amount sufficient to perform, discharge and pay, in full and in cash, all

by lawfully granted, continuously perfected and nonavoidable security interests
in the Lease Collateral, (b) oppose or otherwise contest, or join with any
creditor or the debtor or any trustee or representative in opposing or otherwise
contesting any request by Landlord for relief from any automatic stay or from
any other form of order or restraint for the purpose of permitting such Landlord
to foreclose upon or otherwise enforce any or all of its security interests and
liens upon any Lease Collateral or (c) seek, or join with any creditor or the
debtor or any trustee or representative in seeking, substantive consolidation of
the estate of the debtor with the assets, liabilities or estate of its parent
company or any of its subsidiaries or any other person or entity.

SECTION 6.5       RIGHTS OF LEBONHEUR.

                  Except as set forth herein, LeBonheur, as a creditor, shall
retain the right to vote and otherwise act in any such proceeding, including,
without limitation, the right to file claims in its own behalf and to vote to
accept or reject any plan or partial or complete liquidation, reorganization,

                  7.1.7    Exercise or enforce, in any manner, order or
         sequence, or fail to exercise or enforce, any right or remedy against
         UASC or any collateral security or any other person, entity or property
         in respect of any Lease Obligation or Lease Claim or any security
         interest or lien securing any Lease Obligation or Lease Claim or any
         right under this Agreement, and apply any payment or proceeds of
         collateral in any order of application; and,

                  7.1.8    Sell, exchange, release, foreclose upon, or otherwise
         deal with any property that may at any time be subject to any security
         interest or lien securing any Lease Obligation or Lease Claim.

arising under this Agreement, no change, impairment, or suspension of any right
or remedy of any holder of any Lease Obligation or Lease Claim, and no other

the obligations of LeBonheur under this Agreement or give LeBonheur or any other
person or entity any recourse or defense against any holder of a Lease
Obligation or Lease Claim in respect of any right arising under this Agreement.

SECTION 7.3       REINSTATEMENT OF LEASE CLAIMS AND OBLIGATIONS.

                  If any payment or other transfer at any time applied to the

Lease Obligation or Lease Claim and all rights of the holder of such Lease
Obligation or Lease Claim to enforce subordination as set forth herein shall be
automatically and unconditionally reinstated, as fully as if such payment or
transfer had never been made.

                   ARTICLE 9. LEASE DEFAULT AND ACCELERATION

SECTION 9.1       RIGHT TO CURE.

                  When Landlord gives LeBonheur, as provided in ARTICLE 5
hereof, a Default Notice, LeBonheur shall have the right, but not the
obligation, to undertake to cure such an Event of Default. If LeBonheur
determines to undertake to cure such Event of Default, it will so notify
Landlord within three (3) Business Days after receipt of Landlord's notice, or
it will be deemed to have waived this right. Landlord may exercise any and all
remedies available to it consistent with the provisions of this Agreement while
LeBonheur is considering whether to cure such Event of Default. If LeBonheur
elects to cure such Event of Default, LeBonheur must cure within ten (10)
Business Days of the receipt of such notice such Event of Default as it exists
on the date of cure and not on the date of the Default Notice delivered to
LeBonheur; provided, however, LeBonheur shall have no obligation to then cure
any other Event of Default not stated in the Default Notice.

SECTION 9.2       ACCELERATION NOTICE.

                  Upon any acceleration of the Lease Obligations, a written
notice of acceleration (the "Acceleration Notice") shall be given by the
Landlord to LeBonheur within fifteen (15) Business Days (a Business Day for the
purposes of this Agreement being a day that satisfies the definition of Business
Day in the ASC Lease) of such acceleration. Under certain circumstances
specified in such Lease, the Landlord may be entitled to send out Default
Notices and Acceleration Notices simultaneously, and LeBonheur hereby
acknowledges this right.

SECTION 9.3       OWNERSHIP OF SUBORDINATED OBLIGATIONS.

                  LeBonheur, as creditor, warrants and represents that it has
not previously assigned any interest in the Subordinated Obligations or
Subordinated Claims and that no party other than LeBonheur owns an interest in
the Subordinated Obligations or Subordinated Claims.

                           ARTICLE 10. MISCELLANEOUS

SECTION 10.1      SPECIFIC ENFORCEMENT.

                  UASC and LeBonheur acknowledge and agree that an action for
money damages is not an adequate remedy for enforcement of this Agreement and,
accordingly, agree that each and all of the obligations arising hereunder may,
at the option of the Landlord, be enforced by an action for specific performance
or other lawful specific or injunctive relief.

SECTION 10.2      POWERS AND AUTHORITIES IRREVOCABLE; NO DUTY.

                  All rights, powers and authorities herein granted to the
Landlord are coupled with an interest and are irrevocable until Discharge of the
Lease Obligations and Lease Claims and all outstanding Lease Obligations or
Lease Claims have been performed, discharged and paid in full in cash. Such
rights, powers and authorities may be freely exercised by Landlord, or not
exercised by it, in each instance as it may see fit given its own individual
interest as a holder of a Lease Obligation or Lease Claim, without any duty of
care, duty of loyalty or other duty whatsoever to LeBonheur.

SECTION 10.3      ENFORCEABILITY.

                  This Agreement (a) shall be binding upon and enforceable
against UASC and LeBonheur and their respective successors and assigns whether
such holder of a Subordinated Obligation or Subordinated Claims holds such
Subordinated Claim or Subordinated Obligation as a lien holder, secured party or
otherwise, (b) may be jointly or separately enforced in any lawful manner
against any one or more or all of the persons and entities bound hereby, without
any requirement that other Claims or persons or entities bound

                                       9
<PAGE>

hereby be joined (and no single or partial exercise or enforcement of any right
hereunder shall preclude any other or further exercise or enforcement thereof),
and (c) shall inure to the benefit of and be enforceable by Landlord, its
successors and assigns and transferees and each other present and future holder
of any Lease Obligation or Lease Claim. Without limiting the foregoing, Landlord
shall have the right to assign this Agreement to any Lender of Landlord with
respect to the ASC Lease and LeBonheur hereby agrees to provide such estoppel
certificates to such Lender as may be required and necessary with respect to the
right of the Lender to the benefits of this Agreement.

SECTION 10.4      COMPLETE AGREEMENT; INCONSISTENCY; MODIFICATION; WAIVER.

                  This Agreement, its Exhibits and the ASC Lease, set forth
definitely and exhaustively the complete agreement of the parties with respect
to the subject matter hereof. No provision hereof and no right arising hereunder
may be modified or waived by any oral agreement or shall be deemed to have been
modified or waived by any act or failure to act or shall otherwise be affected
or changed, except as and to the extent expressly set forth in a writing signed
by the party to be bound thereby.

SECTION 10.5      HEADINGS.

SECTION 10.6      GOVERNING LAW; CONSENT TO JURISDICTION.

                  This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Tennessee. UASC and LeBonheur hereby
(a) irrevocably consents to the exclusive jurisdiction of the courts of the
County of Davidson in the State of Tennessee or the courts of the United States
for the Middle District of Tennessee in respect of any action or proceeding
arising out of or in connection with this Agreement or for the enforcement of
any right hereunder, (b) waives any objection which it may have at any time to
the laying of venue of any such action or proceeding in any such court, waives
any claim that such action or proceeding has been brought in an inconvenient
forum, and further waives the right to object that such court does not have
jurisdiction over such party, and (c) agrees that process in any such action or
proceeding may be served upon it, and shall be sufficiently served upon it, by
mail to its address set out on the signature pages hereof; without limiting the
right of any person or entity to serve process in any other manner permitted by
law.

SECTION 10.7      WAIVER OF RIGHT TO TRIAL BY JURY.

                  Each party hereto hereby waives, absolutely, unconditionally,
irrevocably and forever, any right to trial by jury in any action or proceeding
arising out of or in connection with this Agreement or for the enforcement of
any right hereunder.

SECTION 10.8      CONTINUING AND IRREVOCABLE AGREEMENT; ACCEPTANCE.

                  This Agreement is a continuing and irrevocable agreement
enforceable against each signatory party hereto by Landlord and each other
present and future holder of any Lease Obligation or Lease Claim. Notice of
acceptance hereof by Landlord or any such holder is hereby waived, and reliance
hereon by each of them is hereby unconditionally and conclusively acknowledged.

SECTION 10.9      COUNTERPARTS.

                  This Agreement may be executed in any number of counterparts
and by the parties on one or more counterparts, all of which taken together

counterpart.

SECTION 10.10     NOTICES.

                  All notices, requests, demands, and other communications
