119 North Park Avenue, Rockville Centre, New York (the "Premises"); and

         1.       Incorporation by Reference. Reference is hereby made to the
Premises Lease, the Loan Documents, that certain Turnkey License and Services
Agreement between Lessee and Long Island Positron Emission Tomography Scanning,
P.C. (the "Turnkey License") and to the Operating Agreement of Lessee dated as

amended from time to time), the terms of which are incorporated herein by
reference thereto. All capitalized terms used, but not defined herein, shall
have the meanings ascribed to them in such agreements.

         2.       Lease; Sublease.
                  ---------------

                  2.1.     Lease. Subject to the terms of this Lease, Lessor
hereby leases the PET Scanner and the Ancillary Equipment to Lessee during the
Term hereof.

                  2.2.     Title. Nothing contained in this Lease shall give or
convey to Lessee any title or ownership interest in or to the PET Scanner or the
Ancillary Equipment and Lessee hereby acknowledges and agrees that Lessee's
rights under this Lease are subject to and subordinate to the rights of the
Equipment Lender under the Loan Documents, including, without limitation, all
rights of the Equipment Lender as a secured creditor pursuant to its first lien
and security interest in the PET Scanner and the Ancillary Equipment. Lessee
shall, at its expense, protect and defend Lessor's title to the PET Scanner and
the Ancillary Equipment.

                  2.3.     Personalty. The PET Scanner and all of the Ancillary
Equipment leased under this Lease (excluding any leasehold improvements affixed
to the Premises and deemed a part thereof under the Premises Lease) is tangible
personal property and none of the same will be deemed a fixture affixed to or
forming a part of the Premises.

                  2.4.     Disclaimer. Lessee acknowledges that Lessor disclaims
any warranty or representation whatsoever with respect to the PET Scanner and
all items of Ancillary Equipment, including all implied warranties of
merchantability and fitness for a particular purpose and any representation or
warranty that any item thereof is in good operating order, repair and condition
and/or suitable for use in the operation of the PET Center. In addition, Lessee
is accepting the Premises "as is", without any representation or warranty from
Lessor with respect thereto. IN NO EVENT (EXCEPT AS AND TO THE EXTENT OTHERWISE
PROVIDED IN ALL OTHER AGREEMENTS BETWEEN LESSOR AND LESSEE, INCLUDING, WITHOUT
LIMITATION, LESSOR'S GUARANTY UNDER SECTION 7.9 OF THE OPERATING AGREEMENT),
NOTWITHSTANDING ANY PROVISION OF THIS LEASE TO THE CONTRARY, SHALL LESSOR BE
LIABLE FOR ANY LOSS OF USE, REVENUE, ANTICIPATED PROFITS OR SPECIAL, INDIRECT,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR IN CONNECTION WITH THIS
LEASE WITH RESPECT TO THE USE, PERFORMANCE OR MAINTENANCE OF ANY OF SUCH

<PAGE>

EQUIPMENT. If the PET Scanner or any item of Ancillary Equipment is not properly
installed, does not operate as represented or warrantied by the manufacturer,
vendor and/or service company and/or is unsatisfactory for any reason, Lessee
shall make any claim on account thereof solely against the vendor or
manufacturer thereof and/or the service company therefor and shall nevertheless
pay Lessor all amounts payable under this Lease and shall not assert any of such
claims as a defense, counterclaim, deduction, setoff or otherwise against Lessor
or any amounts due under this Lease.

                  2.5.     Warranties. Lessor hereby agrees to transfer to
Lessee all transferrable warranties, service agreements and guarantees relating
to the PET Scanner (collectively, the "Equipment Warranties") and, upon the
request of Lessee and at Lessee's expense, enforce all of such Equipment
Warranties to the extent they are not transferrable.

                  2.6.     Sublease. Lessor hereby subleases the Premises to
Lessee during the Term hereof. Lessee hereby acknowledges and agrees that
Lessee's rights under this Sublease are subject to and subordinate to the rights
of the Landlord under the Premises Lease.

         3.       Term. This Lease is effective as of June 10th, 2002 and will
terminate on June 9th, 2012 (the "Term").

         4.       Rent.
                  ----

                  4.1.     Equipment Rent. Lessee shall pay to Lessor, as rent
for the lease of the PET Scanner and Ancillary Equipment hereunder, an amount
equal to all debt service and other payments, sums and charges due to the
Equipment Lender under the Loan Documents (the "Equipment Rent"). The Equipment
Rent will be due and payable on each date in each month during the Term hereof
that Lessor is required to pay any such debt service, payments, sums and other
charges to the Equipment Lender under the Loan Documents, until such time as
Lessor's obligations to the Equipment Lender under the Loan Documents have been
fully satisfied.

                  If, at any time during the Term of this Lease, Lessor and the
Equipment Lender change the terms of the debt service relating to the sums
borrowed by Lessor to finance its purchase of the PET Scanner and the Ancillary
Equipment, the Equipment Rent shall be adjusted (commencing on the date that any
such change becomes effective) by an amount equal to any such modified debt
service.

                  Notwithstanding the foregoing, Lessee shall not be obligated
to pay any penalties or other charges as part of Equipment Rent to the extent
that any such penalties or other charges are caused by any improper act or
omission of Lessee (unless caused by improper act or omission of Rockville PET,
Inc. ("RPI")).

                                       3
<PAGE>

                  All payments of Equipment Rent (and other amounts payable by
Lessee under this Lease) shall be paid to Lessor by check at the address of
Lessor set forth in Section 12.2 hereof, or at such other address as Lessor
shall designate in writing to Lessee at least five (5) business days prior to
the due date thereof. All payments of Equipment Rent (and other amounts due
under this Lease) shall be paid to Lessor without any deduction, reduction,
abatement or set-off unless otherwise agreed to in writing by Lessor.

                  4.2.     Premises Rent. Lessee shall pay to Lessor, as rent
for the sublet of the Premises hereunder, an amount equal to, but not more than,
the rent as defined in and payable by Lessor to the Landlord under the Premises
Lease (the "Premises Rent"). The Premises Rent will be due and payable monthly,
in advance, on the first day of each month during the Term hereof (or as
otherwise provided under the Premises Lease).

                  All payments of Premises Rent (and other amounts payable by
Lessee under this Sublease) shall be paid to Lessor in the same manner as
provided in Section 4.1 above with respect to Equipment Rent, without any
deduction, reduction, abatement or set-off, unless otherwise agreed to in
writing by Lessor.

                  4.3.     Additional Premises Rent. Lessee hereby acknowledges
and agrees that, in addition to the Premises Rent payable under this Lease,
Lessee shall pay to Lessor any and all other charges and amounts due and payable
by Lessor to the Landlord under the Premises Lease (the "Additional Premises
Rent"), within seven (7) days after Lessee's receipt of notice from Lessor
(which notice will be accompanied by evidence of such additional charges and
amounts).

                  4.4.     Improvements Reimbursement. Subsequent to the date of
this Lease and prior to Lessor's receipt of funding from the Equipment Lender
pursuant to the Loan Documents, Lessor has and/or will advance up to One Hundred
Ten Thousand Dollars ($110,000) (the "Construction Advances") to third party
contractors and other vendors providing materials and services in connection
with improvements to the PET Center requested by Lessee. Lessor has agreed to
make such Construction Advances to enable all improvements required to be made
at the Premises to be completed to the extent that the aforementioned funding
received by Lessor from the Equipment Lender is not sufficient for such
purposes. Lessee shall pay to Lessor, in each month during the Term hereof, an
amount equal to Net Cash Flow (i.e., the amount by which revenues received by
Lessee from its operations each month exceed expenses paid by Lessee in each
month, prior to any debt service payments or profit distributions), until the
Construction Advances have been fully repaid.

                  4.5.     Buy-Out. Lessee shall have the right, at such time as
the Equipment Rent has been fully paid, to purchase the PET Scanner from Lessor
for the sum of $1.00 and all other direct costs incurred by Lessor in connection
with the transfer of title to the PET Scanner from Lessor to Lessee.

Lease or any other agreement between the parties hereto (including, without
limitation, the Operating Agreement), the determination of whether the PET
Scanner has been installed by the manufacturer thereof to the satisfaction of
Lessor and that the PET Scanner has been examined and tested and is in good

Equipment Lender's consent to this Lease.

                  5.5.     Identification. Lessee will, upon the written request
of Lessor, affix plates or other markings indicating the interest of Lessor
and/or the Equipment Lender and/or the Landlord on the PET Scanner and/or on any

                  5.6.     Removal. Lessee shall not remove the PET Scanner or

it has received a copy of the Premises Lease and will, at its cost and expense,

provided in the Loan Documents) and each of Lessor and Lessee agrees to keep the
same free from any liens, claims and encumbrances. Each of Lessor and Lessee
shall promptly notify the other of any such lien, claim or encumbrance.

         6.       Risk of Loss; Insurance.
                  -----------------------

                  6.1.     Risk of Loss. Lessee agrees that it shall bear all
risk of loss, damage to, or destruction to the Premises, PET Scanner and all
items of Ancillary Equipment and shall give Lessor prompt notice of any damage
to or loss thereof. In the event of any damage to any of such equipment, Lessee
shall immediately place such items in good repair (with no abatement of any rent
or other sums due under this Lease) with the proceeds of any insurance recovery
applied to the cost of such repair. If any such equipment is lost, stolen,
destroyed, worn out, damaged beyond repair, confiscated or seized, Lessee shall
replace the same with like equipment in the same condition as the equipment
being replaced (with no abatement of any rent or other amounts due under this
Lease).

                  6.2.     Insurance. Lessee shall maintain, at its cost, all

         7.       Representations and Warranties of Lessor. Lessor hereby
represents and warrants to Lessee the following:

                  7.1.     Good Standing. Lessor is a corporation, duly
organized, validly existing, and in good standing under the laws of the State of
New York and has all requisite power and authority to own and lease its
properties, to carry on its business as currently conducted and as proposed to
be conducted and to consummate the transactions contemplated hereby. Lessor is
duly qualified as a foreign corporation and is in good standing in all such
other jurisdictions in which the current conduct of its business or its
ownership or leasing of property requires such qualification and in which the
failure so to qualify or so to be in good standing would have a materially
adverse effect on Lessor's operations or financial condition.

                  7.2.     Requisite Action. All action on the part of Lessor
necessary for the authorization, execution, delivery and performance of this
Lease and the consummation of the transactions contemplated hereby, has been
properly taken and obtained by it and this Lease constitutes a valid and legally
binding obligation of Lessor enforceable in accordance with its terms, except as
the same may be limited by bankruptcy, insolvency, reorganization, moratorium,
or other laws affecting generally the enforcement of creditors' rights and by
general principles of equity.

                  7.3.     No Conflict. The authorization, execution, delivery
and performance of this Lease and the consummation of the transactions
contemplated hereby and thereby will not result in any violation of or be in
conflict with or constitute, with or without the passage of time or giving of
notice, or both, a breach or default under any instrument, judgment, order,
writ, decree or agreement to which Lessor is a party or by which it is bound.

         8.       Representations and Warranties of Lessee. Lessee hereby
represents and warrants to Lessor the following:

                  8.1.     Good Standing. Lessee is a limited liability company,
duly organized, validly existing, and in good standing under the laws of the
State of New York and has all requisite power and authority to own and lease its
properties, to carry on its business as currently conducted and as proposed to
be conducted and to carry out the transactions contemplated hereby. Lessee is
duly qualified as a foreign limited liability company and is in good standing in
all such other jurisdictions in which the current conduct of its business or its
ownership or leasing of property requires such qualification and in which the
failure so to qualify or so to be in good standing would have a materially
adverse effect on Lessee's operations or financial condition.

<PAGE>

                  8.2.     Requisite Action. All action on the part of Lessee
necessary for the authorization, execution, delivery and performance of this
Lease and the consummation of the transactions contemplated hereby, has been
properly taken and obtained by it and this Lease constitutes a valid and legally
binding obligation of Lessee enforceable in accordance with its terms, except as
the same may be limited by bankruptcy, insolvency, reorganization, moratorium,
or other laws affecting generally the enforcement of creditors' rights and by
general principles of equity.

                  8.3.     No Conflict. The authorization, execution, delivery
and performance of this Lease and the consummation of the transactions
contemplated hereby and thereby will not result in any violation of or be in
conflict with or constitute, with or without the passage of time or giving of
notice, or both, a breach or default under any instrument, judgment, order,
writ, decree or agreement to which Lessee is a party or by which it is bound.

         9.       Assignment and Sublet.
                  ---------------------

                  9.1.     Permitted Use. Lessor hereby agrees that Lessee shall
have the right to make the Premises, the PET Scanner and all items of Ancillary
Equipment available to Rockville PET Imaging, P.C. (the "PC") by assignment,
sublet, license, permit or similar arrangement, provided that the PC agrees, in
writing, to comply with and be bound by the provisions of this Lease and the
Premises Lease and utilizes the Premises, PET Scanner and Ancillary Equipment
solely for the operation of a positron emission tomography diagnostic imaging
center on the Premises (except that, under no circumstances will the PC have any
obligation to pay rent, additional rent, or other sums due thereunder, nor will
the PC be bound by any provision therein which conflicts with, decreases the
rights of, or increases the obligations of the PC under the Turnkey License).
Lessor hereby consents to the Turnkey License.

                  9.2.     Non-Assignability. Lessee shall not have the right to
otherwise assign this Lease or any of Lessee's interest herein, or to sublet the
Premises, in the absence of Lessor's prior written consent.

         10.      Events of Default.
                  -----------------

                  10.1.    The following occurrences shall constitute events of
default under this Lease ("Events of Default"):

                  (a)      Default by Lessee in the payment of any installment
         of Equipment Rent, Premises Rent, and Additional Premises Rent, or
         other charge or amount payable by Lessee hereunder, as and when the
         same becomes due and payable, provided Lessee receives notice thereof
         from Lessor and does not cure such default within ten (10) days after
         such notice (or any such shorter period of time, if any, that Lessor is
         required to make payments of rent, debt service and other sums and
         charges due under the Premises Lease and Loan Documents); or

                                       8
<PAGE>

                  (b)      Breach by Lessor or Lessee of any of their respective
         representations, warranties, covenants or obligations under this Lease;
         provided Lessor or Lessee, as applicable, receives notice thereof and
         fails to cure any such breach within thirty (30) days after such
         notice; or

                  (c)      Upon notice from Lessor, if the Premises Lease is
         terminated or there is an uncured event of default (as defined in the
         Loan Documents) under the Loan Documents; or

                  (d)      Upon a Voluntary Withdrawal or Withdrawal Event of
         Rockville PET, Inc., or a Withdrawal Event of Premier P.E.T.
         International Imaging, Inc. ("Premier") under clause (c) thereof, in
         either instance under and pursuant to the terms of the Operating
         Agreement of Lessee.

                  10.2.    Non-Default. Notwithstanding the foregoing, if any
event occurs which would constitute an Event of Default under this Lease and
such event is caused by Premier, such event will not constitute an Event of
Default hereunder with respect to the sublease to Lessee of the Premises.

                  10.3.    Remedies. Upon the occurrence of any one or more
Events of Default, Lessor or Lessee, as applicable, may, at their option:

                  (a)      Terminate this Lease and, if Lessee breaches or is in
         default of this Lease, Lessor may require Lessee to immediately vacate
         the Premises (likewise, if Lessee elects to terminate this Lease,
         Lessee will immediately vacate the Premises); or

                  (b)      Proceed by appropriate court action, either at law or
         in equity, to enforce performance by Lessor or Lessee, as applicable,
         of the terms and provisions of this Lease and/or to recover from Lessor
         or Lessee, as applicable, any and all reasonable damages or expenses,
         including attorneys' fees, costs and expenses, which Lessor or Lessee,
         as applicable, shall have sustained by reason of any such breach or
         default by Lessor or Lessee, as applicable, or pursue any other
         available legal or equitable remedy; or

                  (c)      Lessor may take possession of and remove the PET
         Scanner and any or all items of Ancillary Equipment, without demand or
         notice, wherever the same may be located, or in lieu of removing any or
         all such items of equipment, make such changes therein at the Premises
         so as to prevent the use thereof by Lessee during the continuation of
         any default by Lessee hereunder, all without any court order or other
         process of law. Lessee hereby waives any and all damage occasioned by
         such taking of possession or making of changes. Any such taking of
         possession or making of such changes shall not constitute a termination
         of this Lease as to any or all items of such equipment, unless Lessor
         expressly so notifies Lessee in writing; or

                                       9
<PAGE>

                  (d)      Demand that Lessee return the PET Scanner, and all
         items of Ancillary Equipment, as, when and where directed by Lessor; or

                  (e)      Demand that Lessee pay all expenses in connection
         with the re-letting of the Premises and retaking of the PET Scanner and
         the Ancillary Equipment; or

Notwithstanding any such taking of possession, or any other action which Lessor
may take after an Event of Default, Lessee shall be and remain liable for the
full performance of all obligations on its part to be performed under this
Lease.

         11.      Indemnification.
                  ---------------

                  11.1.    Indemnification. Lessee shall, at all times during
the Term of this Lease and subsequent thereto, defend, indemnify, and hold
Lessor and its subsidiaries and affiliates and their respective officers,
directors, shareholders, employees and agents (collectively, "Indemnitees")
harmless from and against all claims, causes of action, proceedings, demands,
liabilities, damages, costs, and expenses (including all legal fees and
expenses) (collectively, the "Losses") incurred by Indemnitees (including all
Losses under the Loan Documents), which result from or are based upon any use by
Lessee or any assignee or sublessee of Lessee (including, without limitation,
RPI) of the Premises, the PET Scanner or Ancillary Equipment, or breach of the
Premises Lease by any of them, after the date hereof.

                  11.2.    No Liability. Notwithstanding the foregoing, Lessee
shall not have any liability for indemnification under this Section 11 in the
event that (a) Lessor settles or otherwise disposes of any matter for which it
would otherwise be entitled to indemnification hereunder without the written
consent of Lessee, or (b) any such Losses are caused by any act or omission of
Premier.

                  11.3.    Non-Exclusivity. The indemnification provided for in
this Section shall not be an exclusive remedy for any breach or default by
Lessee of the provisions of this Lease.

                  11.4.    Contribution. In the event that the indemnification
provided for under this Section is unavailable to Lessor in respect of any Loss,
Lessee shall, in lieu of indemnifying Lessor, contribute to the amount paid or
payable by Lessor as a result of any such Loss in such proportion as is
appropriate to reflect the relative fault of such parties in connection with the
matters giving rise to any such Loss.

                  11.5.    Survival. This Section shall survive the Term of this
Lease.

<PAGE>

                  12.6.    Governing Law. This Lease shall be governed by and
construed in accordance with the laws of the State of New York with respect to
contracts made and to be fully performed therein, without regard to the
conflicts of laws principles thereof, except as to applicable federal and state
securities laws. The parties hereto hereby agree that any suit or proceeding
arising under this Lease, or in connection with the consummation of the
transactions contemplated hereby, shall be brought solely in a Federal or state
court located in New York County, or in any court of competent jurisdiction
selected by Lessor, except for any suit or proceeding seeking an equitable
remedy hereunder which may be brought in any court of competent jurisdiction. By
its execution hereof, Lessee hereby consents and irrevocably submits to the in
personam jurisdiction of the Federal and state courts located in New York County
(or any such other court of competent jurisdiction) and agrees that any process
in any suit or proceeding commenced in such courts under this Lease may be
served upon it personally or by certified or registered mail, return receipt
requested, or by Federal Express or other courier service, with the same force
and effect as if personally served upon it in New York City (or in the City or
County in which such other court is located). The parties hereto each waive any
claim that any such jurisdiction is not a convenient forum for any such suit or
proceeding and any defense of lack of in personam jurisdiction with respect
thereto. Nothing in this Section shall affect the right of Lessor to serve legal
process in any other manner permitted by law or affect the right of Lessor to
bring any action or proceeding against Lessee or any of its properties in the
courts of other jurisdictions to the extent otherwise permitted by law.

                  12.7.    Further Assurances. The parties hereto hereby agree
that, at any time and from time to time after the date hereof, upon the
reasonable request of either party hereto, they shall do, execute, acknowledge
and deliver, or cause to be done, executed, acknowledged and delivered, such
further acts, deeds, assignments, transfers, conveyances, and assurances as may
be reasonably required to more effectively consummate this Lease and the
transactions contemplated thereby or to confirm or otherwise effectuate the
provisions of this Lease (including, without limitation, the buy-out provisions
of Section 4.5 hereof).

                  12.8.    Expenses. Except as expressly provided in this Lease,
each of the parties hereto shall bear all of its or their respective costs and
expenses incurred in connection with the negotiation, preparation, execution,
consummation, performance and/or enforcement of this Lease, including, without
limitation, the fees and disbursements of their respective counsel, financial
advisors and accountants. Notwithstanding the foregoing, in the event of any
action or proceeding instituted by either party hereto to enforce the provisions
of this Lease, the party prevailing therein shall be entitled to reimbursement
by the other breaching party(ies) of the legal costs and expenses incurred by
the prevailing party in connection therewith. Lessee hereby acknowledges that
Robert L. Blessey, Esq., Lessor's counsel, drafted this Agreement on behalf of
Lessor and Lessee waives any conflict of interest with respect thereto inasmuch
as Robert L. Blessey, Esq. has also acted as counsel to Lessee and Premier on
transactions unrelated to this Lease.

<PAGE>

                  12.9.    Counterparts. This Lease may be executed in one or
more counterparts, each of which, when executed and delivered, shall be deemed
an original, but all of which when taken together, shall constitute one and the
same instrument.

                  12.10.   Headings. The Section headings used in this Lease
have been used for convenience of reference only and are not to be considered in
construing or interpreting this Lease.

                  12.11.   Partial Invalidity. If one or more provisions of this
Lease are held to be unenforceable under applicable law, such provision(s) shall
be excluded from this Lease and the balance of this Lease shall remain in full
force and effect.

                  12.12.   Cumulative Remedies. No remedy set forth in this
Lease is exclusive of any other available remedy or remedies, whether legal or
equitable, but each remedy is cumulative and in addition to every other right or
remedy given under this Lease or now or hereafter existing at law or in equity
or by statute. The parties hereto may pursue their rights and remedies
concurrently or in any sequence and no exercise of one right or remedy shall be
deemed to be an election. No delay by either party hereto shall constitute a
waiver, election or acquiescence by such party.

                  12.13.   Grammar. Unless the context of this Lease clearly
requires otherwise, the plural includes the singular, the singular includes the
plural, the part includes the whole, "including" is not limiting, and "or" has
the inclusive meaning of the phrase "and/or". The words "hereof", "herein",
"hereby", "hereunder" and other similar terms in this Lease refer to this Lease
as a whole and not exclusively to any particular provision of this Lease.

         IN WITNESS WHEREOF, the parties hereto have hereunto set their hands
and seals as of the day and year first above written.

                                      -----

         LEASE made as of the 1st day of February, 2003, by and between THE

                              ---------------------

         WHEREAS, Lessor has entered into an Agreement of Lease (the "Premises
Lease") with Memphis Ltd. (the "Landlord") for premises located at 21 West 49th
Street, Hialeah, Florida (the "Premises"); and

         WHEREAS, Lessor will enter into a Master Loan Agreement and related
loan documents (collectively, the "Loan Documents") with an independent
equipment lender (the "Equipment Lender") and will purchase the PET Scanner and
Ancillary Equipment which it will, in turn, lease to Lessee for use in
connection with a positron emission tomography imaging center to be established
at the Premises and administered by Lessee (the "PET Center"), and will make
certain improvements to the Premises; and

         WHEREAS, Lessee wishes to sublease the Premises and lease the PET
Scanner and Ancillary Equipment from Lessor, and Lessor is agreeable to doing
so, all on the terms and subject to the conditions hereinafter set forth;

         NOW, THEREFORE, in consideration of the mutual covenants herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby unconditionally acknowledged, the parties hereto do hereby agree as
follows:

         1.       Incorporation by Reference. Reference is hereby made to the
Premises Lease, the Loan Documents, that certain Administrative Services
Agreement between Lessee and Premier P.E.T. of Hialeah, Inc. (the "Management

         2.       Lease; Sublease.

                                       1
<PAGE>

                  2.1.     Lease. Subject to the terms of this Lease, Lessor
hereby leases the PET Scanner and the Ancillary Equipment to Lessee during the
Term hereof.

                  2.2.     Title. Nothing contained in this Lease shall give or
convey to Lessee any title or ownership interest in or to the PET Scanner or the
Ancillary Equipment and Lessee hereby acknowledges and agrees that Lessee's
rights under this Lease are subject to and subordinate to the rights of the
Equipment Lender under the Loan Documents, including, without limitation, all
rights of the Equipment Lender as a secured creditor pursuant to its first lien
and security interest in the PET Scanner and the Ancillary Equipment. Lessee
shall, at its expense, protect and defend Lessor's title to the PET Scanner and
the Ancillary Equipment.

                  2.3.     Personalty. The PET Scanner and all of the Ancillary
Equipment leased under this Lease (excluding any leasehold improvements affixed
to the Premises and deemed a part thereof under the Premises Lease) is tangible
personal property and none of the same will be deemed a fixture affixed to or
forming a part of the Premises.

                  2.4.     Disclaimer. Lessee acknowledges that Lessor disclaims
any warranty or representation whatsoever with respect to the PET Scanner and
all items of Ancillary Equipment, including all implied warranties of
merchantability and fitness for a particular purpose and any representation or
warranty that any item thereof is in good operating order, repair and condition
and/or suitable for use in the operation of the PET Center. In addition, Lessee
is accepting the Premises "as is", without any representation or warranty from
Lessor with respect thereto. IN NO EVENT, NOTWITHSTANDING ANY PROVISION OF THIS
LEASE OR ANY OTHER AGREEMENT TO THE CONTRARY, SHALL LESSOR BE LIABLE FOR ANY
LOSS OF USE, REVENUE, ANTICIPATED PROFITS OR SPECIAL, INDIRECT, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF OR IN CONNECTION WITH THIS LEASE WITH
RESPECT TO THE USE, PERFORMANCE OR MAINTENANCE OF ANY OF SUCH EQUIPMENT. If the
PET Scanner or any item of Ancillary Equipment is not properly installed, does
not operate as represented or warrantied by the manufacturer, vendor and/or
service company and/or is unsatisfactory for any reason, Lessee shall make any
claim on account thereof solely against the vendor or manufacturer thereof
and/or the service company therefor and shall nevertheless pay Lessor all
amounts payable under this Lease and shall not assert any of such claims as a
defense, counterclaim, deduction, setoff or otherwise against Lessor or any
amounts due under this Lease.

                  2.5.     Warranties. Lessor hereby agrees to transfer to
Lessee all transferrable warranties, service agreements and guarantees relating
to the PET Scanner (collectively, the "Equipment Warranties") and, upon the
request of Lessee and at Lessee's expense, enforce all of such Equipment
Warranties to the extent they are not transferrable.

Lessee during the Term hereof. Lessee hereby acknowledges and agrees that

of the Landlord under the Premises Lease.

         3.       Term. This Lease will be for an initial term of ten (10) years
commencing as of February 1, 2003 (subject, however, as a condition precedent to
such effectiveness, to the closing of the financing covered by the Loan
Documents) and shall renew automatically for successive five year periods unless
either party gives the other party at least one-hundred-twenty (120) days notice
prior to the end of the initial term or any of such five year periods of its
intent not to renew this Agreement (the "Term").

         4.       Rent.

for the lease of the PET Scanner and Ancillary Equipment hereunder, an amount
equal to all debt service and other payments, sums and charges due to the
Equipment Lender under the Loan Documents (the "Equipment Rent"). The Equipment
Rent will be due and payable on each date in each month during the Term hereof
that Lessor is required to pay any such debt service, payments, sums and other
charges to the Equipment Lender under the Loan Documents, until such time as
Lessor's obligations to the Equipment Lender under the Loan Documents have been
fully satisfied.

                  If, at any time during the Term of this Lease, Lessor and the
Equipment Lender change the terms of the debt service relating to the sums
borrowed by Lessor to finance its purchase of the PET Scanner and the Ancillary
Equipment, the Equipment Rent shall be adjusted (commencing on the date that any
such change becomes effective) by an amount equal to any such modified debt
service.

                  All payments of Equipment Rent (and other amounts payable by
Lessee under this Lease) shall be paid to Lessor by check at the address of
Lessor set forth in Section 12.2 hereof, or at such other address as Lessor
shall designate in writing to Lessee at least five (5) business days prior to
the due date thereof. All payments of Equipment Rent (and other amounts due
under this Lease) shall be paid to Lessor without any deduction, reduction,
abatement or set-off unless otherwise agreed to in writing by Lessor.

                  4.2.     Premises Rent. Lessee shall pay to Lessor, as rent
for the sublet of the Premises hereunder, an amount equal to, but not more than,
the rent as defined in and payable by Lessor to the Landlord under the Premises
Lease (the "Premises Rent"). The Premises Rent will be due and payable monthly,
in advance, on the first day of each month during the Term hereof (or as
otherwise provided under the Premises Lease).

                  All payments of Premises Rent (and other amounts payable by
Lessee under this Sublease) shall be paid to Lessor in the same manner as
provided in Section 4.1 above with respect to Equipment Rent, without any

                                       3
<PAGE>

deduction, reduction, abatement or set-off, unless otherwise agreed to in
writing by Lessor.

                  4.3.     Additional Premises Rent. Lessee hereby acknowledges
and agrees that, in addition to the Premises Rent payable under this Lease,
Lessee shall pay to Lessor any and all other charges and amounts due and payable
by Lessor to the Landlord under the Premises Lease (the "Additional Premises
Rent"), within seven (7) days after Lessee's receipt of notice from Lessor
(which notice will be accompanied by evidence of such additional charges and
amounts).

                  4.4.     Buy-Out. Lessee shall have the right, at such time as
the Equipment Rent has been fully paid, to purchase the PET Scanner from Lessor
for the sum of $1.00 and all other direct costs incurred by Lessor in connection
with the transfer of title to the PET Scanner from Lessor to Lessee.

         5.       Covenants; Obligations.
                  ----------------------

                  5.1.     Use. Lessee shall use the PET Scanner and all items
of Ancillary Equipment solely on the Premises and in connection with the
operation of a PET Center. Lessee shall, at its cost, protect the PET Scanner
and all items of Ancillary Equipment from and against all damage and
deterioration, other than normal wear and tear and will, at all times during the
Term hereof, use and operate the PET Scanner and all items of Ancillary
Equipment in accordance with all applicable manufacturer and/or vendor manuals,
instructions and/or warranties and service agreements, and otherwise in
accordance with all applicable laws, rules and regulations.

                  5.2.     Maintenance. Lessee shall maintain and repair the PET
Scanner and all items of Ancillary Equipment by fully qualified and authorized
personnel and in compliance with all applicable warranties and service
agreements, and manufacturer and/or vendor manuals or instructions and shall be

Term hereof, except for any loss or damage caused by any intentional act of
Lessor with respect thereto. Upon request of Lessor, Lessee shall, at reasonable
times during normal business hours, make the PET Scanner and/or any item of
Ancillary Equipment available to Lessor (or to the Landlord and/or Equipment
Lender) for inspection and shall make Lessee's repair and maintenance records
with respect to the PET Scanner, Ancillary Equipment and the Premises available
to such parties.

                  5.3.     Loan Document Compliance. Lessee shall operate the

requirements under the Premises Lease and the Loan Documents.

                  5.4.     Identification. Lessee will, upon the written request
of Lessor, affix plates or other markings indicating the interest of Lessor

Documents.

                  5.6.     Prohibitions. Lessee shall not, at any time during
the Term hereof, (i) use, operate or locate the PET Scanner or any item of
Ancillary Equipment in any area excluded from coverage by any insurance required
under this Lease, (ii) abandon the PET Scanner and/or any item of Ancillary
Equipment or alter the same, (iii) affix or install any accessory, equipment or
device on the PET Scanner or on any item of the Ancillary Equipment if such is
not readily removable or will otherwise impair the originally intended function
or use of such equipment or is otherwise in violation of any product warranty or
any product operating manual, or (iv) make any distributions of net profits to
its members upon notice from Licensor after an Event of Default (hereinafter
defined) by Lessee hereunder.

                  5.7.     Premises Lease Compliance. Lessee acknowledges that
it has received a copy of the Premises Lease and will, at its cost and expense,
comply with all obligations and covenants provided for thereunder as if it were
the Tenant thereunder (including all such obligations and covenants thereunder
that Lessor shall notify Lessee of, in writing, from time to time during the
Term hereof). Lessee will conduct its operations on the Premises in accordance
with all applicable provisions and requirements under the Premises Lease.

                  5.8.     Access. Upon request of Lessor, Lessee shall, at
reasonable times during normal business hours, make the Premises, PET Scanner
and Ancillary Equipment available to Lessor (or to the Equipment Lender or
Landlord) for inspection or as otherwise requested by the Landlord or Equipment
Lender in accordance with the provisions of the Premises Lease and/or the Loan
Documents.

                  5.9.     Encumbrances. Neither Lessor nor Lessee shall sell,
transfer, assign, sublet, pledge or otherwise encumber any interest in this
Lease and/or in the Premises and/or in the PET Scanner and/or in any item of
Ancillary Equipment (except as provided in Section 9.1 hereof or as otherwise
provided in or required under the Loan Documents) and each of Lessor and Lessee
agrees to keep the same free from any liens, claims and encumbrances. Each of
Lessor and Lessee shall promptly notify the other of any such lien, claim or
encumbrance.

         6.       Risk of Loss; Insurance.
                  -----------------------

                  6.1.     Risk of Loss. Lessee agrees that it shall bear all
risk of loss, damage to, or destruction to the Premises, PET Scanner and all
items of Ancillary Equipment and shall give Lessor prompt notice of any damage
to or loss thereof. In the event of any damage to any of such equipment, Lessee
shall immediately place such items in good repair (with no abatement of any rent
or other sums due under this Lease) with the proceeds of any insurance recovery
applied to the cost of such repair. If any such equipment is lost, stolen,
destroyed, worn out, damaged beyond repair, confiscated or seized, Lessee shall

                                       5
<PAGE>

replace the same with like equipment in the same condition as the equipment
being replaced (with no abatement of any rent or other amounts due under this
Lease).

                  6.2.     Insurance. Lessee shall maintain, at its cost, all
insurance coverages requested by Lessor, all of which shall name Lessor as an
additional insured as its interests may appear and provide for thirty (30) days
prior notice to Lessor of any cancellation, termination or modification thereof.
Lessee shall provide Lessor, upon request, with evidence of the maintenance of
such insurance throughout the Term of this Lease.

         7.       Representations and Warranties of Lessor. Lessor hereby
represents and warrants to Lessee the following:

                  7.1.     Good Standing. Lessor is a corporation, duly
organized, validly existing, and in good standing under the laws of the State of
New York and has all requisite power and authority to own and lease its
properties, to carry on its business as currently conducted and as proposed to
be conducted and to consummate the transactions contemplated hereby. Lessor is
duly qualified as a foreign corporation and is in good standing in all such
other jurisdictions in which the current conduct of its business or its
ownership or leasing of property requires such qualification and in which the
failure so to qualify or so to be in good standing would have a materially
adverse effect on Lessor's operations or financial condition.

                  7.2.     Requisite Action. All action on the part of Lessor
necessary for the authorization, execution, delivery and performance of this
Lease and the consummation of the transactions contemplated hereby, has been
properly taken and obtained by it and this Lease constitutes a valid and legally
binding obligation of Lessor enforceable in accordance with its terms, except as
the same may be limited by bankruptcy, insolvency, reorganization, moratorium,
or other laws affecting generally the enforcement of creditors' rights and by
general principles of equity.

                  7.3.     No Conflict. The authorization, execution, delivery
and performance of this Lease and the consummation of the transactions
contemplated hereby and thereby will not result in any violation of or be in
conflict with or constitute, with or without the passage of time or giving of
notice, or both, a breach or default under any instrument, judgment, order,
writ, decree or agreement to which Lessor is a party or by which it is bound.

         8.       Representations and Warranties of Lessee. Lessee hereby
represents and warrants to Lessor the following:

                  8.1.     Good Standing. Lessee is a limited liability company,
duly organized, validly existing, and in good standing under the laws of the
State of Florida and has all requisite power and authority to own and lease its
properties, to carry on its business as currently conducted and as proposed to

                                       6
<PAGE>

be conducted and to carry out the transactions contemplated hereby. Lessee is
duly qualified as a foreign limited liability company and is in good standing in
all such other jurisdictions in which the current conduct of its business or its
ownership or leasing of property requires such qualification and in which the
failure so to qualify or so to be in good standing would have a materially
adverse effect on Lessee's operations or financial condition.

                  8.2.     Requisite Action. All action on the part of Lessee
necessary for the authorization, execution, delivery and performance of this
Lease and the consummation of the transactions contemplated hereby, has been
properly taken and obtained by it and this Lease constitutes a valid and legally
binding obligation of Lessee enforceable in accordance with its terms, except as
the same may be limited by bankruptcy, insolvency, reorganization, moratorium,
or other laws affecting generally the enforcement of creditors' rights and by
general principles of equity.

                  8.3.     No Conflict. The authorization, execution, delivery
and performance of this Lease and the consummation of the transactions
contemplated hereby and thereby will not result in any violation of or be in
conflict with or constitute, with or without the passage of time or giving of
notice, or both, a breach or default under any instrument, judgment, order,
writ, decree or agreement to which Lessee is a party or by which it is bound.

         9.       Assignment and Sublet.
                  ---------------------

                  9.1.     Permitted Use. Lessor hereby agrees that Lessee shall
have the right to make the Premises, the PET Scanner and all items of Ancillary
Equipment available to Eiber Radiology, Inc. (the "PC") by assignment, sublet,
license, permit or similar arrangement, provided that the PC agrees, in writing,
to comply with and be bound by the provisions of this Lease and the Premises
Lease and utilizes the Premises, PET Scanner and Ancillary Equipment solely for
the operation of a positron emission tomography diagnostic imaging center on the
Premises (except that, under no circumstances will the PC have any obligation to
pay rent, additional rent, or other sums due thereunder). Lessor hereby consents
to the Management Agreement.

                  9.2.     Non-Assignability. Lessee shall not have the right to
otherwise assign this Lease or any of Lessee's interest herein, or to sublet the
Premises, in the absence of Lessor's prior written consent, except as required
under the Loan Documents.

         10.      Events of Default.
                  -----------------

                  10.1.    The following occurrences shall constitute events of
default under this Lease ("Events of Default"):

                                       7
<PAGE>

                  (a)      Default by Lessee in the payment of any installment
         of Equipment Rent, Premises Rent, or Additional Premises Rent, or other
         charge or amount payable by Lessee hereunder, as and when the same
         becomes due and payable, provided Lessee receives notice thereof from
         Lessor and does not cure such default within ten (10) days after such
         notice (or any such shorter period of time, if any, that Lessor is
         required to make payments of rent, debt service and other sums and
         charges due under the Premises Lease and Loan Documents); or

                  (b)      Breach by Lessor or Lessee of any of their respective
         representations, warranties, covenants or obligations under this Lease;
         provided Lessor or Lessee, as applicable, receives notice thereof and
         fails to cure any such breach within thirty (30) days after such
         notice; or

                  (c)      Upon notice from Lessor, if the Premises Lease is
         terminated or there is an uncured event of default (as defined in the
         Loan Documents) under the Loan Documents.

                  10.2.    Remedies. Upon the occurrence of any one or more
Events of Default, Lessor or Lessee, as applicable, may, at their option:

                  (a)      Terminate this Lease and, if Lessee breaches or is in
         default of this Lease, Lessor may require Lessee to immediately vacate
         the Premises (likewise, if Lessee elects to terminate this Lease,
         Lessee will immediately vacate the Premises); and/or

                  (b)      Proceed by appropriate court action, either at law or
         in equity, to enforce performance by Lessor or Lessee, as applicable,
         of the terms and provisions of this Lease and/or to recover from Lessor
         or Lessee, as applicable, any and all reasonable damages or expenses,
         including attorneys' fees, costs and expenses, which Lessor or Lessee,
         as applicable, shall have sustained by reason of any such breach or
         default by Lessor or Lessee, as applicable, or pursue any other
         available legal or equitable remedy; and/or

                  (c)      Lessor may take possession of and remove the PET
         Scanner and any or all items of Ancillary Equipment, without demand or
         notice, wherever the same may be located, or in lieu of removing any or
         all such items of equipment, make such changes therein at the Premises
         so as to prevent the use thereof by Lessee during the continuation of
         any default by Lessee hereunder, all without any court order or other
         process of law. Lessee hereby waives any and all damage occasioned by
         such taking of possession or making of changes. Any such taking of
         possession or making of such changes shall not constitute a termination
         of this Lease as to any or all items of such equipment, unless Lessor
         expressly so notifies Lessee in writing; and/or

                  (d)      Demand that Lessee return the PET Scanner, and all
         items of Ancillary Equipment, as, when and where directed by Lessor;
         and/or

                                       8
<PAGE>

                  (e)      Demand that Lessee pay all expenses in connection
         with the re-letting of the Premises and retaking of the PET Scanner and
         the Ancillary Equipment.

Notwithstanding any such taking of possession, or any other action which Lessor
may take after an Event of Default, Lessee shall be and remain liable for the
full performance of all obligations on its part to be performed under this
Lease.

         11.      Indemnification.
                  ---------------

                  11.1.    Indemnification. Lessee shall, at all times during
the Term of this Lease and subsequent thereto, defend, indemnify, and hold
Lessor and its subsidiaries and affiliates and their respective officers,
directors, shareholders, employees and agents (collectively, "Indemnitees")
harmless from and against all claims, causes of action, proceedings, demands,
liabilities, damages, costs, and expenses (including all legal fees and
expenses) (collectively, the "Losses") incurred by Indemnitees (including all
Losses under the Loan Documents), which result from or are based upon any use by
Lessee or any assignee or sublessee of Lessee (including, without limitation,
the PC) of the Premises, the PET Scanner or Ancillary Equipment, or breach of
the Premises Lease by any of them, after the date hereof.

                  11.2.    No Liability. Notwithstanding the foregoing, Lessee
shall not have any liability for indemnification under this Section 11 in the
event that (a) Lessor settles or otherwise disposes of any matter for which it
would otherwise be entitled to indemnification hereunder without the written
consent of Lessee, or (b) any such Losses are caused by any act or omission of
Premier.

                  11.3.    Non-Exclusivity. The indemnification provided for in
this Section shall not be an exclusive remedy for any breach or default by
Lessee of the provisions of this Lease.

                  11.4.    Contribution. In the event that the indemnification
provided for under this Section is unavailable to Lessor in respect of any Loss,
Lessee shall, in lieu of indemnifying Lessor, contribute to the amount paid or
payable by Lessor as a result of any such Loss in such proportion as is
appropriate to reflect the relative fault of such parties in connection with the
matters giving rise to any such Loss.

                  11.5.    Survival. This Section shall survive the Term of this
Lease.

         12.      Miscellaneous.
                  -------------

                  12.1.    Sole and Entire Agreement. This Lease constitutes the
sole and entire agreement between the parties hereto with respect to the subject
matter hereof and supersedes all prior agreements, representations, warranties,
statements, promises, information, arrangements and understandings, whether oral
or written, express or implied, between the parties hereto with respect to the
subject matter hereof and may not be changed or modified except by an instrument
in writing signed by the party to be bound thereby. No course of conduct or

                                       9
<PAGE>

dealing or trade usage or custom or course of performance by the parties hereto
shall constitute or be relied upon as a modification, supplement, or waiver of
any provision of this Lease. This Lease has been subject to the mutual
consultation, negotiation and agreement of the parties hereto and shall not be
construed for or against either party hereto on the basis of such party having
drafted this Lease.

                  12.2.    Notices. All notices, consents, requests, demands and
other communications required or permitted to be given under this Lease (the
"Notices") shall be in writing and delivered personally, receipt acknowledged,

requested, addressed to the parties hereto as follows (or to such other

                           Hialeah, Florida
                           Attn: Stephen A. Schulman, M.D., Manager

                                       10
<PAGE>

All such Notices shall be deemed given when personally delivered as aforesaid,
or, if mailed as aforesaid, on the third business day after the mailing thereof
or on the day actually received, if earlier, except for a notice of a change of
address which shall be effective only upon receipt.

                  12.3.    Non-Assignability. Neither party hereto may assign
this Lease or its or their respective rights, benefits or obligations hereunder
without the written consent of the other party hereto, except as provided in
Section 9.1 and except that Lessor may assign its rights to payments under this
Lease upon notice to Lessee.

                  12.4.    Binding Effect. This Lease shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
permitted assigns. Nothing contained in this Lease is intended to confer upon
any person or entity, other than the parties hereto, or their respective
successors or permitted assigns, any rights, benefits, obligations, remedies or
liabilities under or by reason of this Lease.

                  12.5.    Waiver. No waiver of any provision of this Lease or
of any breach thereof shall be effective unless in writing and signed by the
party to be bound thereby. The waiver by either party hereto of a breach of any
provision of this Lease, or of any representation, warranty, obligation or
covenant in this Lease by the other party hereto, shall not be construed as a
waiver of any subsequent breach or of any other provision, representation,
warranty, obligation or covenant of such other party, unless the instrument of
waiver expressly so provides.

                  12.6.    Governing Law. This Lease shall be governed by and
construed in accordance with the laws of the State of Florida with respect to
contracts made and to be fully performed therein, without regard to the
conflicts of laws principles thereof. The parties hereto hereby agree that any
suit or proceeding arising under this Lease, or in connection with the
consummation of the transactions contemplated hereby, shall be brought solely in
a Federal or state court located in Dade County, or in any court of competent
jurisdiction selected by Lessor, except for any suit or proceeding seeking an
equitable remedy hereunder which may be brought in any court of competent
jurisdiction. By its execution hereof, Lessee hereby consents and irrevocably
submits to the in personam jurisdiction of the Federal and state courts located
in Dade County (or any such other court of competent jurisdiction) and agrees
that any process in any suit or proceeding commenced in such courts under this
Lease may be served upon it personally or by certified or registered mail,
return receipt requested, or by Federal Express or other courier service, with
the same force and effect as if personally served upon it in Dade County (or in
the City or County in which such other court is located). The parties hereto
each waive any claim that any such jurisdiction is not a convenient forum for
any such suit or proceeding and any defense of lack of in personam jurisdiction
with respect thereto. Nothing in this Section shall affect the right of Lessor
to serve legal process in any other manner permitted by law or affect the right
of Lessor to bring any action or proceeding against Lessee or any of its
properties in the courts of other jurisdictions to the extent otherwise
permitted by law.

                  12.7.    Further Assurances. The parties hereto hereby agree
that, at any time and from time to time after the date hereof, upon the
reasonable request of either party hereto, they shall do, execute, acknowledge
and deliver, or cause to be done, executed, acknowledged and delivered, such

                                       11
<PAGE>

further acts, deeds, assignments, transfers, conveyances, and assurances as may
be reasonably required to more effectively consummate this Lease and the
transactions contemplated thereby or to confirm or otherwise effectuate the
provisions of this Lease (including, without limitation, the buy-out provisions
of Section 4.5 hereof).

                  12.8.    Expenses. Except as expressly provided in this Lease,
each of the parties hereto shall bear all of its or their respective costs and
expenses incurred in connection with the negotiation, preparation, execution,
consummation, performance and/or enforcement of this Lease, including, without
limitation, the fees and disbursements of their respective counsel, financial
advisors and accountants. Notwithstanding the foregoing, in the event of any
action or proceeding instituted by either party hereto to enforce the provisions
of this Lease, the party prevailing therein shall be entitled to reimbursement
by the other breaching party(ies) of the legal costs and expenses incurred by
the prevailing party in connection therewith. Lessee hereby acknowledges that
Robert L. Blessey, Esq., Lessor's counsel, drafted this Agreement on behalf of
Lessor and Lessee waives any conflict of interest with respect thereto inasmuch
as Robert L. Blessey, Esq. has also acted as counsel to Lessee on transactions
unrelated to this Lease.

                  12.9.    Counterparts. This Lease may be executed in one or
more counterparts, each of which, when executed and delivered, shall be deemed
an original, but all of which when taken together, shall constitute one and the
same instrument.

                  12.10.   Headings. The Section headings used in this Lease
have been used for convenience of reference only and are not to be considered in
construing or interpreting this Lease.

                  12.11.   Partial Invalidity. If one or more provisions of this
Lease are held to be unenforceable under applicable law, such provision(s) shall
be excluded from this Lease and the balance of this Lease shall remain in full
force and effect.

                  12.12.   Cumulative Remedies. No remedy set forth in this
Lease is exclusive of any other available remedy or remedies, whether legal or
equitable, but each remedy is cumulative and in addition to every other right or
remedy given under this Lease or now or hereafter existing at law or in equity
or by statute. The parties hereto may pursue their rights and remedies
concurrently or in any sequence and no exercise of one right or remedy shall be
deemed to be an election. No delay by either party hereto shall constitute a
waiver, election or acquiescence by such party.

                  12.13.   Grammar. Unless the context of this Lease clearly
requires otherwise, the plural includes the singular, the singular includes the
plural, the part includes the whole, "including" is not limiting, and "or" has
the inclusive meaning of the phrase "and/or". The words "hereof", "herein",
"hereby", "hereunder" and other similar terms in this Lease refer to this Lease
as a whole and not exclusively to any particular provision of this Lease.

                                       12
