being hereinafter  referred to as the "Premises", and (ii) Tenant's Pro Rata
Share of the Common Areas located within the Building (on a nonexclusive basis)
which, for purposes of this Lease, is the equivalent of an additional gross
area of 708 square feet (the "Additional Area").  Landlord retains, and Tenant
grants to Landlord, an irrevocable license for Landlord's and Landlord's other
tenants' employees, agents, customers and invitees to enter upon and pass
through the Premises in a mutually agreeable location or locations in order to
have access to and from the portion of the Building in the northeast quadrant

III.     COMMON AREAS.

         Landlord grants unto Tenant, its invitees, customers, employees and
agents the non-exclusive right to use all areas, equipment and facilities
within the Building that are not designated for the exclusive use of any

The Common Areas shall at all times be
<PAGE>   2
subject to the exclusive control and management of Landlord, and Tenant's use
of the Common Areas shall be subject to such reasonable rules and regulations
as Landlord may from time to time impose. Tenant agrees to abide by such rules
and regulations and use Tenant's best efforts to cause its employees, agents,
customers and invitees to conform thereto.

IV.      TERM.

                 (A)  Term.  Unless sooner terminated under the terms and
         provisions of Section XVII of this Lease, the term of this Lease shall
         be five (5) years commencing on the 8th day of February, 1996 and
         ending on the 7th day of February, 2001 (the "Term").

                 (B)  Surrender and Holdover.  Upon the expiration or sooner
         termination of this Lease, Tenant shall surrender to Landlord the
         Premises, together with all other property affixed to the Premises
         (excepting trade fixtures), "broom clean" and in the same order and
         condition in which Tenant received said Premises, ordinary wear and
         tear excepted.  Unless an event of default as hereinafter defined has
         occurred and remains uncured, Tenant, prior to the expiration of the
         Term shall remove all of Tenant's trade fixtures and personal property
         from the Premises.  Any damage to the Premises caused by such removal
         shall be repaired by Tenant prior to the expiration of the Term.  At
         Landlord's option, if Tenant fails to remove such trade fixtures and
         personal property, then the same shall be deemed Landlord's property.
         If Tenant remains in possession of all or any part of the Premises
         after the expiration of the Term, with the consent of the Landlord,
         then Tenant shall be deemed to be occupying the Premises as a tenant
         from month to month at the rent hereinafter specified (pro rated on a
         monthly basis), subject to all conditions, provisions and obligations
         of this Lease insofar as the same are applicable to month-to-month
         tenancy.  Landlord's acceptance of rent after the expiration of the
         term shall not constitute a renewal or extension of this Lease, and
         this provision shall not be deemed to waive Landlord's right of
         re-entry or any other right or remedy hereunder or provided by law.

V.       RENT.

                 (A)  Minimum Rental.  Tenant shall pay to Landlord without
         prior demand therefor a minimum rental for the Premises and Additional
         Area (hereinafter referred to as "Minimum Rental") of Four Hundred
         Thirteen Thousand Eight Hundred Fifty Dollars ($413,850) during the
         Term, payable in equal monthly installments of Six Thousand Eight
         Hundred Ninety-Seven and 50/100 Dollars ($6897.50) each, in advance on
         the first day of each calendar month of the Term.

                 (B)  Additional Rental.  In addition to the Minimum Rental,
         Tenant shall pay to Landlord, with respect to each calendar year or
         fractional calendar year during the Term, Tenant's Pro Rata Share of
         Landlord's Real Property Taxes and Operating Expenses (as hereinafter
         defined) as additional rental.  The term "Real Property Taxes"
         includes all ad valorem real property taxes and currently due
         installments of assessments levied upon

                                      2

<PAGE>   3
         or with respect to the Real Estate and all taxes, levies and charges
         which may be levied or imposed by any governmental authority in
         replacement of, in lieu of, or in addition to ad valorem real property
         taxes, in whole or in part, including, but not limited to, a state or
         local option tax designed for property tax relief purposes, or a
         license or franchise fee measured by rents received from the Building,
         or otherwise measured or based upon Landlord's interest in the
         Building.  (The term "Real Property Taxes" does not include any income
         tax.)  The term "Operating Expenses" means all costs and expenses of
         every kind and nature paid or incurred by Landlord (including
         appropriate reserves) for the owning, operating, managing, equipping,
         lighting, heating, cooling, repairing, replacing, cleaning, painting,
         maintaining and insuring the Building and the Common Areas in
         accordance with standards customary for first class office buildings
         located in Indianapolis, Indiana, excluding only depreciation of the
         cost of initial construction of the Building.  As used in this Lease
         the Tenant's "Pro Rata Share" means twenty-nine and 38/100 percent
         (29.38%).  Tenant's Pro Rata Share of Real Property Taxes and
         Operating Expenses (hereinafter "Additional Rental") for each calendar
         year or fractional calendar year during the Term shall be paid
         promptly, without demand therefor, in estimated monthly installments
         in advance on the first day of each calendar month of the Term, which
         estimated monthly installments during the initial year of the Term
         shall be Two Thousand Five Hundred Twenty-Nine and 08/100 Dollars
         ($2529.08) each.  On or before the 7th day of February, 1997, and on
         or before the 7th day of February of each subsequent year during the
         Term, Landlord shall deliver to Tenant a written statement of the
         estimated monthly installments of Additional Rental that Tenant shall
         pay Landlord during the twelve month period beginning each February 8
         during the Term.  Not later than August 8, 1996 and February 8, 1997,
         and each August and February thereafter during the Term, Landlord
         shall furnish Tenant a statement in reasonable detail of the actual
         Real Property Taxes and Operating Expenses paid or incurred by
         Landlord in the preceding six (6) month period ending June 30 and
         December 31 prepared in accordance with sound accounting principles
         and practices.  Should the Tenant's Pro Rata Share of the actual Real
         Property Taxes and Operating Expenses paid or incurred by Landlord
         during such six (6) month period exceed the Additional Rental that
         Tenant is required to pay in monthly installments during such six (6)
         month period, then Tenant shall pay the excess amount to Landlord
         within thirty (30) days after Tenant receives such statement to the
         end that Landlord shall receive the entire amount of Tenant's Pro Rata
         Share of such Real Property Taxes and Operating Expenses.  Should the
         Additional Rental that Tenant has paid during such six (6) month
         period exceed Tenant's Pro Rata Share of the actual Real Property
         Taxes and Operating Expenses paid or incurred by Landlord during such
         six (6) month period, then Landlord shall remit the excess amount to
         Tenant within thirty (30) days after Tenant receives such statement.
         (The dates of such statements and six (6) month periods may, at the
         option of Landlord, be subject to change.)

VI.      USE AND OCCUPANCY.

         The Premises may be used and occupied by Tenant for the purposes of
administrative offices of Tenant and/or its subsidiaries and for the operation
of a clinic providing infusion services, and for no other purpose or purposes
without Landlord's consent.  Tenant shall not do or permit anything to be done
in or about the Premises, or bring or keep anything therein, which will in any
way increase the rate of fire insurance upon the Premises or the Building
wherein the Premises are situated.  Tenant shall comply with all laws,
ordinances, orders and regulations affecting the Premises and the cleanliness,
safety, occupation and use thereof.

         Tenant shall not cause or permit injury or waste to the Premises or
the Building or cause or permit a nuisance to exist, and shall keep the
Premises clean and free from rubbish and dirt at all times, and shall store all
trash and garbage within the Premises and arrange for the regular pickup of
such trash and garbage at Tenant's expense.  Tenant shall not burn any trash or
garbage of any kind in or about the Premises or Building.

VII.     ADDITIONAL SPACE.

         Portions of the Building are currently leased to Roche Biomedical
Laboratories, Inc. ("Roche Biomedical") (831 square feet as its occupied space
plus 122 square feet as its pro rata share of the Common Areas), Roche
Professional Service Centers, Inc. ("Roche Professional") (2,756 square feet as
its occupied space plus 406 square feet as its pro rata share of the Common
Areas) and Northwest Radiologist, P.C. ("Northwest") (1,614 square feet as its
occupied space plus 238 square feet as its pro rata share of Common Areas)
(Roche Biomedical, Roche Professional and Northwest collectively being the
"Other Tenants").  The locations of the space currently occupied by each of the
Other Tenants in the Building is depicted on Exhibit C attached hereto.
Because Tenant needs additional space for its business purposes, Tenant hereby
agrees to lease the space occupied by Roche Professional (plus its pro rata
share of the Common Areas), and to take a first right of refusal on and lease,
if Tenant so elects, the space occuped by Roche Biomedical, (plus Roche
Biomedical's pro rata share of the Common Areas) and the space occupied by
Northwest (plus Northwest's pro rata share of the Common Areas) if such space
becomes vacant and available for rent to Tenant (which shall be determined in
Landlord's sole discretion) during the Term (i) for the remainder of the Term,
(ii) at the same per square foot rent as the Minimum Rent is for the Premises
and the Additional Area (which is $15 per square foot per year), and (iii) on
the other terms and conditions (including, without limitation, the payment of
Additional Rental with respect thereto) in this Lease.  If Tenant receives
written notice from Landlord that Roche Biomedical's space or Northwest's space
is vacant and available to rent, Tenant shall have five (5) days after its
receipt of such notice to notify Landlord that Tenant has decided to lease the
Roche Biomedical space or the Northwest space, as the case may be.  In the
event that Tenant does not notify Landlord as herein provided after receipt of
written notice from Landlord, Tenant shall have no further interest or rights
to the Roche Biomedical space or the Northwest space, as the case may be, and
Landlord shall have no further obligations to Tenant with respect to the Roche
Biomedical space or the Northwest space, as the case may be.  Tenant's
agreement as stated in this Section VII shall be a standing offer that is
acceptable






                                      4
<PAGE>   5
by Landlord in writing at any time prior to three (3) months before the end of
the Term with respect to the space in the Building currently occupied by either
of the Other Tenants.  Upon the leasing of any such additional space by Tenant,
an appropriate and mutually acceptable amendment to this Lease (and an amended
or additional Memorandum of Lease for recording purposes) shall be prepared by
Landlord and executed by Landlord and Tenant to evidence the leasing of such
additional space by Tenant.

VIII.    RIGHTS OF LANDLORD TO MORTGAGE LEASED PREMISES.

         This Lease, and the rights of Tenant hereunder, shall be, and hereby
are, subject and subordinate to the lien or liens of any mortgage or mortgages,
now or at any time hereafter in force against the title of Landlord, or any
successor to Landlord, in and to the Real Estate, and to all advances made or
hereafter to be made upon the security thereof, including, but not limited to,
the mortgage of the Real Estate in favor of The American National Bank of
Vincennes dated February 28, 1994, and recorded in the Office of the Recorder,
Hamilton County, Indiana on March 9, 1994 as Instrument No. 9411353.  Tenant
shall execute and deliver whatever instruments may be required to subordinate
this Lease to the lien or liens of any such mortgage or mortgages, and in the
event Tenant fails to do so within ten (10) days after demand in writing,
Tenant does hereby make, constitute and irrevocably appoint Landlord as its
attorney-in- fact, and in its name and stead, to execute such instruments.

         If by reason of any default on the part of Landlord as mortgagor under
any mortgage or mortgages to which this Lease is subordinate, any such mortgage
is foreclosed by legal proceedings or extinguished by conveyance in lieu of
foreclosure or otherwise, Tenant, upon the election of the holder of any such
mortgage, but not otherwise, will attorn to and recognize such mortgage holder
and its successors and assigns, including any purchaser in foreclosure or a
grantee of a deed in lieu thereof, as Landlord under this Lease.  Tenant shall
execute and deliver at any time, upon request of Landlord or any holder of a
mortgage to which this Lease is subordinate, an instrument to evidence such
attornment and containing the agreement of Tenant that no action taken to
enforce any such mortgage by reason of any default thereunder shall terminate
this Lease or invalidate or constitute a breach of any of the terms thereof.
This obligation on the part of Tenant to attorn is entirely independent of and
not contingent upon the foregoing subordination provisions of this Section
VIII.

         The terms and provisions of this Lease may require approval by a
mortgagee.  If any such mortgagee should require as a condition to Landlord's
financing, as may be determined necessary or desirable by Landlord, any
modification of the terms and provisions of this Lease, other than provisions
relating to rent or term, and the right to use and occupy the Premises for the
purposes described in Section VII, and if Tenant should refuse to approve and
execute any modifications so required, then Landlord shall have the right by
notice  given to Tenant thirty (30) days in advance to cancel this Lease
without liability on the part of Landlord.

         outside of the Building of which the Premises form a part (but
         excluding the exterior and interior of all windows, doors, plate
         glass, show cases and store fronts), excluding any damage thereto
         caused by Tenant, its agents or invitees.  Tenant shall pay to
         Landlord in the manner provided in Section V(B) of this Lease Tenant's
         Pro Rata Share of costs incurred by Landlord under this Section X(A).

                 (B)  Tenant's Responsibility.  Tenant shall keep and maintain
         the Premises and every part thereof, and the exterior and interior
         portions of all doors, windows, plate glass, show cases and the store
         front surrounding the Premises in good order, condition and repair,
         including, without limitation, all plumbing, heating, air conditioning
         and sewage facilities within the Premises, fixtures, interior walls,
         floors, ceilings, signs and all interior building appliances and
         similar equipment, except for reasonable use and ordinary wear and
         tear.

                 (C)  Alterations.  Tenant shall have the right, with the
         written consent of Landlord, to make alterations to the interior of
         the Premises so long as the cost thereof is paid by Tenant and all
         such work is done in a workmanlike manner and without damage to the
         structural elements of the Premises and in conformance with the
         regulations of fire insurance underwriters carrying insurance on the
         Premises. Tenant agrees that upon expiration or termination of this
         Lease it will, at its own expense, if Landlord shall so request,
         restore the Premises to their former condition, ordinary wear and tear
         and damage by the elements excepted.

                 (D)  Signs and Awnings.  Tenant shall not affix to or upon the
         exterior of the Premises signs or awnings except with the prior
         written consent of Landlord.

                 (E)  Personal Property on Premises - Risk of Damage.
         Notwithstanding anything expressed or implied to the contrary in this
         Lease, Tenant agrees that all personal property of every kind or
         description which may at any time be in the Premises shall be at
         Tenant's sole risk, or at the risk of those claiming through or under
         the Tenant, and Landlord shall not be liable for and shall be held
         harmless by Tenant against claims for any damage to said property or
         loss suffered by the business or property of the Tenant arising from
         bursting, overflowing or leaking of water, sewer or steam pipes or
         from the heating or plumbing fixtures, or from the electric wiring or
         from gas or odors or caused in any manner.

                 (F)  Trade Fixtures.  All improvements to the Premises and all
         fixtures shall be and become the property of the Landlord, except that
         all machinery and equipment installed by the Tenant and all trade
         fixtures, including cabinets, installed or used by the






                                      6
<PAGE>   7
         Tenant shall remain the personal property of the Tenant.  Any damage
         to the Premises caused by the installation or removal of trade
         fixtures or personal property shall promptly be repaired by Tenant at
         its expense.

                 (G)  Liens.  Tenant shall not cause or permit the creation of
         any lien against the Premises or the Building on account of any labor
         or materials furnished in connection with maintenance, repairs or
         alterations undertaken by Tenant.  In the event any such lien shall be
         filed against the Premises or the Building, Tenant shall cause such
         lien to be released within ten (10) days after actual notice of the
         filing thereof or shall furnish to Landlord a bond, satisfactory to
         Landlord, conditioned to indemnify Landlord against the foreclosure of
         such lien.

                 (H)  Inspection and Repair by Landlord.  Landlord shall have
         the right to enter at reasonable times upon the Premises for the
         purpose of inspection or to make such improvements, repairs or
         alterations as it may consider expedient, but Landlord assumes no
         obligation to make any improvements, repairs or alterations except as
         expressly provided in this Lease.

X.       INDEMNITY AND INSURANCE.

         Each party to this Lease agrees to indemnify and save harmless the
other against and from any and all claims by or on behalf of any person, firm
or corporation arising from any breach or default in the performance of any
covenant or agreement on its part to be performed under this Lease.

         Tenant shall indemnify, protect, defend and hold Landlord harmless
from all injury, damages, actions, suits, proceedings, losses, claims and
liabilities that may occur or be claimed by or with respect to any persons,
corporations, entities, property or chattels on or about the Premises resulting
from any act done or omission by the Tenant, its servants, invitees or agents,
or caused by, or resulting from or relating to Tenant's use, non-use or
possession thereof, or Tenant's conduct of its business therein or thereon.
Tenant hereby agrees to pay, discharge and defend Landlord against any and all
such claims, litigation, suits, proceedings, and demands.  The indemnification
provided by this paragraph shall include Landlord's legal costs and attorneys'
fees in connection with any such claim, action or proceeding.

         Landlord covenants at all times to save Tenant harmless from all loss,
cost or damages which may occur or be claimed with respect to any persons,
corporations, entities, property or chattels on or about the Premises, or to
the property itself, resulting from the gross negligence of Landlord or its
servants or agents.

         Tenant, in order to insure against the liabilities specified in this
Lease, agrees to place and maintain, at Tenant's own expense, with insurance
companies qualified to do business in the State of Indiana and acceptable to
Landlord, comprehensive general liability and property damage insurance with
respect to Tenant's use and occupancy of the Premises with a single






                                      7
<PAGE>   8
combined liability limit of Three Million Dollars ($3,000,000).  Such insurance
shall include premises operation, bodily injury, personal injury, death, broad
form contractual liability, completed operations, broad form property damage
coverage and products liability.  Such insurance shall be for the benefit of
the Landlord and shall name the Landlord as an insured.  Tenant agrees to
furnish certificates of such insurance to Landlord.  Such insurance policies
shall contain an endorsement requiring thirty (30) days' advance notice from
the insurance company to Landlord before cancellation or change in the
coverage, scope, or amount of any policy.

         Tenant shall furnish at its own cost and expense replacement insurance
for any cracked or broken glass, including plate glass and interior and
exterior windows and doors in the Premises, provided, however, that Landlord
will replace any glass that is cracked or broken by any casualty covered by
fire and extended coverage or other insurance of the Landlord or caused by a
structural defect or settling of the Building in which the Premises are
located.

         Landlord shall keep the Real Estate insured against loss or damage by
fire and such other risks as are usually and customarily included within the
term "extended coverage," as deemed advisable by Landlord, but such insurance
shall not cover Tenant's trade fixtures, furnishings, equipment or any items of
personal property on the Premises.  Tenant shall pay Tenant's Pro Rata Share of
any expenses incurred by Landlord in obtaining and maintaining such insurance,
and Tenant's pro rata share of such expenses shall be calculated and paid in
the manner specified in Section V(B) of this Lease with respect to the payment
of Operating Expenses.

         Tenant shall carry such insurance against loss of its property in the
Premises by fire or other hazards as Tenant deems necessary.  Landlord shall
not be liable for any damage to Tenant's property in the Premises, and Tenant
expressly releases Landlord of and from all liability for any such damage.
Tenant agrees that its insurance policy or policies shall include a waiver of
subrogation recognizing this release from liability.

XI.      CASUALTY PROVISIONS.

         If either the Building or the Premises should be substantially
destroyed or damaged (which, as used herein, means destruction or material
damage to at least fifty percent (50%) of the Building or the Premises) by fire
or other casualty, or if Landlord's uninsured and/or underinsured portion of
the loss resulting from any fire or other casualty affecting the Building or
the Premises exceeds $100,000 in the aggregate, then in either such case
Landlord may terminate this Lease by giving written notice of such termination
to Tenant within sixty (60) days after the date of such casualty.  In such
event, rent shall be apportioned to and shall cease as of the date of such
casualty.  (For purposes of this Lease, a loss of Landlord that is "uninsured
or underinsured" means a loss or partial loss as to which Landlord is not
reimbursed by insurance proceeds that are available to reconstruct or restore
the Building or Premises, including, without limitation, losses not insured due
to policy deductibles, losses as to which a mortgagee of the Real Estate
applied available insurance proceeds to indebtedness secured by the Real
Estate, or other circumstances resulting in insurance proceeds payable and
available to Landlord with respect to a loss being less than the amount of the
loss).  If Landlord does not exercise this





                                      8
<PAGE>   9
option to terminate, then the Premises shall be reconstructed and restored, at
Landlord's expense, to substantially the same condition as it was prior to the
casualty; provided however, that Landlord's obligation hereunder shall be
limited to the reconstruction of the Premises as originally existed upon
commencement of this Lease, and further provided that if Tenant has made any
improvements to the Premises Tenant shall reimburse Landlord for the cost of
reconstructing the same.  In the event of such reconstruction, monthly
installments of Minimum Rental and Tenant's Pro Rata Share of Operating
Expenses shall be abated from the date of the casualty until substantial
completion of the reconstruction repairs; and this Lease shall continue in full
force and effect for the balance of the Term.  In addition to the foregoing, if
the Premises should be substantially destroyed or damaged (which, as used
herein, means destruction or material damage to at least fifty percent (50%) of
the Premises) so that such portion is unusable for the permitted purposes under
this Lease, and it shall require more than sixty (60) days to repair and
restore the Premises, Tenant shall have the right to terminate this Lease by
giving written notice of such termination to Landlord within ten (10) days
after receipt of notice from the Landlord of the time it will take to complete
the repair and restoration of the Premises.  Landlord shall provide written
notice to Tenant of the time it will take to repair and restore the Premises
within fifteen (15) days after the fire or other casualty.

         If the Premises should be damaged by fire or other casualty but not
substantially destroyed or damaged to the extent provided in Section 10.1 and
if the uninsured and/or underinsured loss attributable thereto does not exceed
$100,000 in the aggregate, then such damaged part of the Premises shall be
reconstructed and restored by Landlord at Landlord's expense to substantially
the same condition as it was prior to the casualty; provided however, that
Landlord's obligation hereunder shall be limited to the reconstruction of the
Premises as originally existed upon commencement of this Lease, and further
provided that if Tenant has made any additional improvements to the Premises
Tenant shall reimburse Landlord for the cost of reconstructing the same.  In
such event, if the damage is expected to prevent Tenant from carrying on its
business in the Premises to an extent exceeding fifty percent (50%) of its
normal business activity, monthly installments of Minimum Rental shall be
abated in the proportion which the approximate area of the damaged part bears
to the total area in the Premises from the date of the casualty until
substantial completion of the reconstruction repairs; and this Lease shall
continue in full force and effect for the balance of the Term.  Landlord shall
use reasonable diligence in completing such reconstruction repairs.  In
addition to the foregoing, if the Premises should be partially destroyed as
described in this paragraph so that such portion is unusable for the permitted
proposes under this Lease, and it shall require more than sixty (60) days to
repair and restore the Premises, Tenant shall have the right to terminate this
Lease by giving written notice of such termination to Landlord within ten (10)
days after receipt of notice from the Landlord of the time it will take to
complete the repair and restoration of the Premises.  Landlord shall provide
written notice to the Tenant of the time it will take to repair and restore the
Premises within fifteen (15) days after the fire or other casualty.

         The provisions of this Section are not intended to limit, modify or
release Tenant from any liability it may have for damages.

<PAGE>   10
         Notwithstanding the foregoing provisions of this Section XI, if the
unexpired portion of the Term is less than one year at the time a fire or other
casualty renders all or not less than fifty percent (50%) of the Premises
untenantable for Tenant's permitted use hereunder, Tenant may terminate this
Lease upon written notice of termination to Landlord at any time within ten
(10) days after the date of such fire or other casualty.

XII.     CONDEMNATION.

         If the Premises are condemned or taken in whole or in part by any
public authority under the power of eminent domain, either Landlord or Tenant
shall have the right as of the day possession shall be taken by such public
authority to terminate this Lease by notice thereof to the other in writing and
rent shall be paid to the date of such possession or proportionate refund made
by the Landlord if rent has been paid in advance.  If neither party shall elect
to terminate this Lease by reason of such condemnation, the Minimum Rent shall
be reduced by the proportion of the floor area of the Premises taken by such
condemnation and Landlord shall make all necessary repairs or alterations so as
to constitute the remaining Premises a complete architectural unit.

         All damages awarded for such taking, whether for a whole or a part of
the Premises, shall belong to and be the property of the Landlord, whether such
damages shall be awarded as compensation for diminution in value to the
leasehold or to the fee of the Premises; provided, however, that the Landlord
shall not be entitled to the award made to Tenant for loss of business or
depreciation to or the cost of removal of stock and trade fixtures.

XIII.    UTILITIES/JANITORIAL SERVICE AND TRASH REMOVAL.

         Landlord shall furnish utility services to the Real Estate, including,
without limiting the generality thereof, electricity, telephone, gas, heat,
water and air conditioning, and Tenant shall pay Tenant's Pro Rata Share of
such charges that shall be calculated and paid in the manner specified in
Section V(B) of this Lease with respect to the payment of Operating Expenses,
provided, however, that Tenant shall pay directly to the utility providing the
same all charges for utilities that are supplied exclusively to the Premises
and are separately metered and/or billed with respect to the Premises.

         Landlord shall provide janitorial service and trash removal service
for the Real Estate, and Tenant shall pay Tenant's Pro Rata Share of the
charges for such services that shall be calculated and paid in the manner
specified in Section V(B) of this Lease with respect to the payment of
Operating Expenses; provided, however, that the removal of Medical Wastes (as
hereinafter defined) from the Premises shall be in accordance with Section XIV
of this Lease.

from the Premises of Medical Wastes all costs and expenses in connection with
such disposal or removal.  In the event any of such costs and expenses for the

Tenant shall immediately reimburse Landlord upon Landlord's submitting a
written statement to Tenant for such costs and expenses.

         In Tenant's handling of Medical Wastes, including, without limitation,

enforcement action mandated or taken by any governmental authority with respect
to Tenant's handling of Medical Wastes on or about the Premises, or in any

                 first given to the Tenant; or

                          (vi)    The abandonment of the Leased Premises by 
                 Tenant.

                 (B)  Remedies.  Upon the occurrence of any Event of Default,

                          (ii)    Terminate this Lease at any time upon the

                 Premises without the same being deemed an acceptance of a
                 surrender of this Lease nor a waiver of Landlord's rights or
                 remedies and Landlord shall be entitled to Indemnity Payments,
                 as hereinafter defined, from Tenant.  Any re-letting by
                 Landlord may be for a period equal to or less than, or
                 extending beyond the remainder of the Term, or for the whole
                 or any part of the Premises, separately or with other
                 premises, or for any reasonable sum, or to any lessee or for
                 any use Landlord deems appropriate.

                          (iv)    Liquidated Damages means an amount equal to
                 the excess of the rentals including the Minimum Rental and
                 Additional Rental, provided for in this Lease which would have

                 terminated, for the period commencing with such termination
                 and ending with the date set for the expiration of the Term
                 (hereinafter the "Unexpired Term"), over the reasonable rental
                 value of the Premises for such Unexpired Term.

                          (v)     "Indemnity Payments" means an amount equal to
                 the rentals, including the Minimum Rent and Additional Rent,
                 and other payments provided for in this Lease which would have
                 become due and owing thereunder from time to time during the
                 Unexpired Term plus the cost and expenses paid or incurred by
                 Landlord from time to time in connection with:

                          the Premises;

                 collected and allocable to the Premises or to the portions
                 thereof re-let by Landlord.  Tenant shall on demand make
                 Indemnity Payments monthly and Landlord can sue for all
                 Indemnity Payments as they accrue.

         Landlord shall be entitled to recover its costs and reasonable
attorney fees incurred in enforcing against Tenant any covenant, term or
condition of this Lease and/or in pursuing its remedies under this Section XVI
or pursuing other remedies available to Landlord under the law.

XVIII.  ADVANCES AND INTEREST.

Event of Default for the account and at the expense of Tenant.  If Landlord, in
