Lease Payment, together with all accrued interest thereon is paid in full. If
GKF shall at any time accept a Lease Payment from Hospital after it shall become

billings and collections for each Gamma Knife procedure performed during that
month, including, without limitation, the amount of the claim submitted and the
amount received for each such procedure. Upon request by GKF, Hospital shall
furnish to GKF information regarding reimbursement rates from any or all payor
sources for Gamma Knife procedures (applicable to procedures performed either on
an inpatient or outpatient basis). If such reimbursement rates should change at
any time or from time to time after the date hereof, in each instance, Hospital
shall provide written notice thereof to GKF within thirty (30) days of Hospital
receiving notice thereof. All information provided to GKF by Hospital with
regard Gamma Knife procedure charges, billing and reimbursement rates shall

acknowledges that Patient Medical Information is confidential pursuant to
applicable State and federal law ("Applicable Privacy Law"), including but not
limited to, privacy standards imposed pursuant to the federal Health Insurance
Portability and Accountability Act of 1996 ("HIPAA"). GKF agrees, therefore,
that:

      a.    Any Patient Medical Information it, its employees or agents receive
            regarding Hospital's patients shall be treated as confidential so as
            to comply with Applicable Privacy Law. GKF agrees to indemnify and
            hold harmless Hospital, its officers, directors, employees and
            agents from any breech of such confidentiality by GKF, its employees
            or agents. This provision shall survive termination of this
            Agreement.

      b.    In the event that the Department of Health and Human Services, the
            Office of Civil Rights Enforcement, the Centers for Medicaid
            Services, the Agency for Health Care Administration or legal counsel
            advice Hospital that this Agreement does not, or must be amended to,
            comply with Applicable Privacy Law, Hospital may, at its sole
            option, (i) modify this Agreement to the extent reasonably necessary
            and reasonably acceptable to GKF to bring it into compliance, or
            (ii) require GKF to enter into a separate HIPAA- compliant Business
            Associate agreement with Hospital.




            8.4   The parties acknowledge that the rental payments to GKF and
the reimbursement of costs and Space Rental to Hospital reflects fair market
value compensation to GKF for the Gamma Knife and Hospital for space used for
the Gamma Knife are not determined in a manner that takes into account the

(270) days prior to the expiration of the initial Term. Any such notice shall be
sufficient if it states in substance that Hospital elects to exercise its option
and states which of the two (2) options referred to above Hospital is
exercising. If Hospital fails to exercise the option granted herein at least Two
hundred seventy


                                       10

(270) days prior to the expiration of the initial Term, the option shall lapse
and this Agreement shall expire as of the end of the initial Term.

      20.   Events of Default by Hospital and Remedies.

            20.1  The occurrence of any one of the following shall constitute an
event of default under this Agreement (an "Event of Default"):

                  20.1.1 Hospital fails to pay any Lease Payment when due
pursuant to Paragraph 8 above and such failure continues for a period of thirty
(30) days after written notice thereof is given by GKF or its assignee to
Hospital; however, if Hospital cures the payment default within the applicable
thirty (30) day period, such default shall not constitute an Event of Default.

                  20.1.2 Hospital attempts to remove, sell, transfer, encumber,
assign, sublet or part with possession of the Equipment or any items thereof,
except as expressly permitted herein.

                  20.1.3 Hospital fails to observe or perform any of its
covenants, duties or obligations arising under this Agreement or the LGK
Agreement and such failure continues for a period of thirty (30) days after
written notice thereof by GKF to Hospital; however, if Hospital cures the
default within the applicable thirty (30) day period or if the default
reasonably requires more than thirty (30) days to cure, Hospital commences to
cure the default during the initial thirty (30) day period and Hospital
diligently completes the cure as soon as reasonably possible following the end
of the thirty (30) day period, such default shall not constitute an Event of
Default.

                  20.1.4 Hospital ceases doing business as a going concern,
makes an assignment for the benefit of creditors, admits in writing its
inability to pay its debts as they become due, files a voluntary petition in
bankruptcy, is adjudicated a bankrupt or an insolvent, files a petition seeking
for itself any reorganization, arrangement, composition, readjustment,
liquidation, dissolution or similar arrangement under any present or future
statute, law or regulation or files an answer admitting the material allegations
of a petition filed against it in any such proceeding, consents to or acquiesces
in the appointment of a trustee, receiver, or liquidator of it or of all or any
substantial part of its assets or properties, or it or its shareholders shall
take any action looking to its dissolution or liquidation

                  20.1.5 Within sixty (60) days after the commencement of any
proceedings against Hospital seeking reorganization, arrangement, readjustment,
liquidation, dissolution or similar relief under any present or future statute,
law or regulation, such proceedings shall not have been dismissed, or if within
thirty (30) days after the appointment without Hospital's consent or
acquiescence of any trustee, receiver or liquidator of it or of all or any
substantial part of its assets and properties, such appointment shall not be
vacated.

            20.2  Upon the occurrence of an Event of Default with respect to
Hospital, GKF may at its option do any or all of the following:

                  20.2.1 By written notice to Hospital, immediately terminate
this Agreement as to the Equipment, wherever situated. As a result of the
termination, GKF may enter upon the Site and remove the Equipment and any
improvements made by GKF to the Site without liability of any kind or nature for
so doing or GKF may demand that Hospital remove and return the Equipment and
such improvements to GKF, all at Hospital's sole cost and expense.

                  20.2.2 Recover damages from Hospital as may be awarded by a
court of competent jurisdiction for the loss of the bargain represented by this
Agreement. For purposes of determining such damages, the parties agree that the
following methodology shall be used: (a) the amount of such damages shall be
equal to the present value of the unpaid estimated future Lease Payments to be
made by Hospital to GKF through the end of the Term discounted at the rate of
nine percent (9%); and (b) the unpaid estimated future Lease Payments shall be
based on the historical trend of payments made by Hospital to GKF hereunder
taking into account known factors which could impact the historical trend
through the end of the Term. Hospital and GKF acknowledge that the methodology
set forth in this Section 20.2.2 constitutes a reasonable method to calculate
GKF's damages resulting from an Event of Default under the circumstances
existing as of the date of this Agreement. GKF shall use reasonable commercial
efforts to mitigate its damages by attempting to sell or lease the Equipment;
provided that (i) GKF shall not be obligated to give preference to the sale or
lease of the Equipment over the sale, lease or other disposition of similar
equipment or improvements owned or leased by GKF, (ii) GKF shall have no
obligation to sell or lease any improvements made by GKF to the Site, and (iii)
GKF's inability in good faith to mitigate damages shall not limit or otherwise
affect the foregoing methodology for determining damages as set forth in this
Section.

                  20.2.3 Sell, dispose of, hold, use or lease the Equipment or
any improvements made by GKF to the Site, as GKF in its sole and absolute
discretion may determine (and GKF shall not be obligated to give preference to
the sale, lease or other disposition of the Equipment or improvements over the
sale, lease or other disposition of similar Equipment or improvements owned or
leased by GKF).

                  20.2.4 Exercise any other right or remedy which may be
available to GKF under the Uniform Commercial Code or any other applicable law
or proceed by appropriate court action, without affecting GKF's title or right
to possession of the Equipment or improvements, to enforce the terms hereof or
to recover damages for the breach hereof or to cancel this Agreement as to the
Equipment.

In addition to the foregoing remedies, Hospital shall be liable to GKF for all
reasonable costs and expenses incurred by GKF as a result of the Event of
Default or the exercise of GKF's remedies.


                                       12
<PAGE>
            20.3  Upon termination of this Agreement or the exercise of any
other rights or remedies under this Agreement or available under applicable law
following an Event of Default, Hospital shall, without further request or
demand, pay to GKF all Lease Payments and other sums then owing under this
Agreement. Hospital shall in any event remain fully liable for all damages as
may be provided by law and for all costs and expenses incurred by GKF on account
of such default, including but not limited to, all court costs. The rights and
remedies afforded GKF under this Agreement shall be deemed cumulative and not
exclusive, and shall be in addition to any other rights or remedies to GKF
provided by law or in equity.

      21.   Events of Default by GKF and Remedies.

            21.1  The occurrence of any one of the following shall constitute an
Event of Default hereunder:

                  21.1.1 GKF shall fail to observe or perform any of its
covenants, duties or obligations arising under this Agreement and such failure
shall continue for a period of thirty (30) days after written notice thereof is
given by Hospital to GKF; however, if GKF cures the default within the
applicable thirty (30) day period or if the default reasonably requires more
than thirty (30) days to cure, GKF commences to cure the default during the
initial thirty (30) day period and GKF diligently completes the cure as soon as
reasonably possible following the end of the thirty (30) day period, such
default shall not constitute an Event of Default.

                  21.1.2 GKF ceases doing business as a going concern, makes an
assignment for the benefit of creditors, admits in writing its inability to pay
its debts as they become due, files a voluntary petition in bankruptcy, is
adjudicated a bankrupt or an insolvent, files a petition seeking for itself any
reorganization, arrangement, composition, readjustment, liquidation, dissolution
or similar arrangement under any present or future statute, law or regulation or
files an answer admitting the material allegations of a petition filed against
it in any such proceeding, consents to or acquiesces in the appointment of a
trustee, receiver, or liquidator of it or of all or any substantial part of its
assets or properties, or it or its shareholders shall take any action looking to
its dissolution or liquidation.

                  21.1.3 Within sixty (60) days after the commencement of any
proceedings against GKF seeking reorganization, arrangement, readjustment,
liquidation, dissolution or similar relief under any present or future statute,
law or regulation, such proceedings shall not have been dismissed, or if within
thirty (30) days after the appointment without GKF's consent or acquiescence of
any trustee, receiver or liquidator of it or of all or any substantial part of
its assets and properties, such appointment shall not be vacated.

            21.2  Upon the occurrence of an Event of Default involving GKF,
Hospital may at its option do any or all of the following:

                  21.2.1 By written notice to GKF, immediately terminate this
Agreement as to the Equipment and, in such event, GKF shall remove the
Equipment, the Cobalt and any


                                       13
<PAGE>
improvements made by GKF to the Site, at GKF's sole cost and expense or, in the
absence of removal by GKF within a reasonable period of time after a written
request therefor, Hospital may remove the Equipment, the Cobalt and such
improvements with all due care and store the same at GKF's sole cost and
expense.

                  21.2.2 Seek to recover from GKF such loss as may be realized
by Hospital in the ordinary course of events as a result of the Event of
Default.

            21.3  GKF shall in any event remain fully liable for reasonable
damages as provided by law and for all costs and expenses incurred by GKF on
account of such default, including but not limited to, all court costs (other
than attorneys' fees). However, GKF shall not in any manner be or become liable
to Hospital for any consequential or incidental damages that may be suffered by
Hospital which arise out of or result from the Event of Default, except as
otherwise stated in Section 24.1. The rights and remedies afforded Hospital
under this Agreement shall be deemed cumulative to include the purchase option
contained in section 18.3 and not exclusive and shall be in addition to any
other rights or remedies to Hospital provided by law or in equity.

            21.4  Notwithstanding the occurrence of an Event of Default with
respect to GKF (including any claim which would otherwise be in the nature of a
set-off), Hospital shall fully perform and pay its obligations hereunder
(including payment of all Lease Payments) without set-off or defense of any
kind. Upon termination of this Agreement or the exercise of any other rights or
remedies under this Agreement or applicable law following an Event of Default,
Hospital shall, without further request or demand, pay to GKF all Lease Payments
and other sums and owing under this Agreement when and as due.

      22.   Removal of Equipment. Upon expiration of the Term, GKF, at its cost
and expense, shall remove the Equipment from the Site not more than ninety (90)
days following the last day of the Term; provided that all of GKF's right, title
and interest in and to the improvements made by GKF to the Site pursuant to
Section 6 above shall thereupon transfer to Hospital.

      23.   Insurance.

            23.1  During the Term, GKF shall, at its cost and expense, purchase
and maintain in effect an all risk property and casualty insurance policy
covering the Equipment. The all risk property and casualty insurance policy
shall be for an amount not less than the replacement cost of the Equipment. The
all risk property and casualty insurance policy maintained by GKF shall be
evidenced by a certificate of insurance or other reasonable documentation which
shall be delivered by GKF to Hospital upon request following the commencement of
this Agreement and as of each annual renewal of such policy during the Term.

            23.2  During the Term, Hospital shall, at its cost and expense,
purchase and maintain in effect professional liability insurance covering the
use or operation of the Equipment


                                       14
<PAGE>
by Hospital's employees and agents. The professional liability insurance
policies shall provide coverage in amounts not less than Five Hundred Thousand
Dollars ($500,000.00) per occurrence and One and One half Million Dollars
($1,500,000.00) annual aggregate. The policies to be maintained by Hospital
hereunder shall be evidenced by a certificate of insurance or other reasonable
documentation which shall be delivered by Hospital to GKF no later than the
First Procedure Date and as of each annual renewal of such policies during the
Term. Hospital shall require any physicians using the equipment to show evidence
of professional liability insurance consistent with Hospital's Medical Staff
Bylaws.

            23.3  During the construction of the Site and prior to the First
Procedure Date, GKF, at its cost and expense, shall purchase and maintain a
general liability insurance policy which conforms with the coverage amounts and
other requirements described in Section 23.2 above and which names Hospital as
an additional insured party. The policy to be maintained by GKF hereunder shall
be evidenced by a certificate of insurance or other reasonable documentation
which shall be delivered by GKF to Hospital prior to the commencement of any
construction at the Site.

            23.4  During the Term, Hospital shall purchase and maintain all
workers compensation insurance to the maximum extent required by applicable law.

      24.   Indemnification.

            24.1  Hospital and GKF each hereby covenants and agrees that it will
defend, indemnify and hold the other party and the other party's officers,
directors, members, employees and agents at all times harmless from and against
any loss, damage and expense (including reasonable attorneys' fees and other
costs of defense) caused by or arising out of: (i) any liability or obligation
related to the business of the indemnifying party prior to the date hereof; (ii)
any obligation or liability arising from services provided under this Agreement
by the indemnifying party to the extent any such liability or obligation
directly results from the negligence or intentional misconduct of the
indemnifying party, it's employees or agents ; or (iii) any obligation or
liability resulting from a breach of any provision of this Agreement by the
indemnifying party, it's employees or agents. The obligations of the parties
under this Section shall survive the expiration or earlier termination of this
Agreement.

            24.2  Any party that intends to enforce an indemnity obligation
shall give the indemnifying party notice of any claim as soon as possible, but
the failure to give such notice shall not constitute a waiver or release of the
indemnifying party and shall not affect the rights of the indemnified party to
recover under this indemnity, except to the extent the indemnified party is
materially prejudiced thereby. In connection with any claim giving rise to
indemnity under this Section resulting from or arising out of any claim or legal
proceeding by a person who is not a party to this Agreement, the indemnifying
party, at its sole cost and expense, may, upon written notice to the indemnified
party, assume control of the defense of such claim or legal proceeding, to the
extent that the indemnifying party admits in writing its indemnification
liability to the indemnified party with respect to all material elements
thereof. If the indemnifying party assumes the defense of any such claim or
legal proceeding, the obligations of the indemnifying


                                       15
<PAGE>
party hereunder as to such claim or legal proceeding shall be to take all steps
necessary in the defense or settlement thereof and to hold the indemnified party
harmless from and against any losses, damages, expenses or liability caused by
or arising out of any settlement approved by the indemnifying party and the
indemnified party or any judgment in connection with such claim or legal
proceeding. Each indemnified party shall cooperate with the indemnifying party
in the defense of any such action, the defense of which is assumed by the
indemnifying party. Except with the consent of the indemnified party, which
consent may be withheld at the indemnified party's sole discretion, the
indemnifying party shall not consent to any settlement or the entry of any
judgment arising from any such claim or legal proceeding which, in each case,
does not include as an unconditional term thereof the delivery by the claimant
or the plaintiff to the indemnified party of a release from all liability in
respect thereof. If the indemnifying party does not assume the defense of any
claim or litigation, any indemnified party may defend against such claim or
litigation in such manner as it may deem appropriate, including but not limited
to settling such claim or litigation, after giving notice of the same to the
indemnifying party, on such terms as the indemnified party may deem appropriate.
The indemnifying party will, promptly after any of the same is incurred,
reimburse the indemnified party in accordance with the provisions hereof for all
damages, losses, liabilities, costs and expenses incurred by the indemnified
party.

      25.   Miscellaneous.

            25.1  Binding Effect. This Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
assigns. Except as provided under Section 14, neither party shall assign this
Agreement nor any of its respective rights hereunder and Hospital shall not
sublease the Equipment without the prior written consent of the other party,
which consent shall not be unreasonably withheld. An assignment or sublease
shall not relieve the assigning party or sublessor of any liability for
performance of this Agreement during the remainder of the Term. Any purported
assignment or sublease made without the other party's prior written consent
shall be null, void and of no force or effect.

            25.2  Agreement to Perform Necessary Acts. Each party agrees to
perform any further acts and execute and deliver any further documents which may
be reasonably necessary or otherwise reasonably required to carry out the
provisions of this Agreement.

            25.3  Validity. If for any reason any clause or provision of this
Agreement, or the application of any such clause or provision in a particular
context or to a particular situation, circumstance or person, should be held
unenforceable, invalid or in violation of law by any court or other tribunal of
competent jurisdiction, then the application of such clause or provision in
contexts or to situations, circumstances or persons other than that in or to
which it is held unenforceable, invalid or in violation of law shall not be
affected thereby, and the remaining clauses and provisions hereof shall
nevertheless remain in full force and effect.

prevailing party.

the intent.

            25.7  Effect of Headings. The titles or headings of the various

the State of Florida applicable to agreements made and to be performed in that
State.

            25.10 Exhibits. All exhibits attached hereto and referred to in this

that any provision of this Agreement is found to be ambiguous, each party shall
have an opportunity to present evidence as to the actual intent of the parties
with respect to such ambiguous provision.

            25.12 Representations. Each of the parties hereto represents (a)

Agreement, or to exercise any right, power or remedy hereunder or under law or
consequent upon a breach hereof or thereof shall constitute a waiver of any such

breach or preclude such party from exercising any such right, power or remedy at
any later time or times.

            25.14 Notices. All notices, requests, demands or other
