servants, visitors and patients shall have the right of ingress and egress

services, Lessee's Use of the Space, or deprive Lessee, its agents, 
employees, servants, invitees and visitors or patients of ingress and 
egress to or from the Space, the Building or the Complex.

     3.3     Use Availability
             ----------------

     It shall be Lessee's responsibility to determine and, if necessary,
submit the appropriate applications for the Use of the Space to the

                                   ----

     4.1     Subject to adjustment based upon the final square footage 
determination of the Space, Lessee agrees to pay as base rent to Lessor 
for the use of the Space during the Term $7.50 per square foot or Fifty-
two Thousand Five Hundred and 00/100 ($52,500.00) Dollars per year 
("Rent") to be paid in monthly installments of Four Thousand Three 
Hundred Seventy-five and 00/100 ($4,375.00) Dollars, payable monthly in 
advance on the due date, which is the first day of each calendar month 
during the Term, allowing ten (10) day check processing time.  The Rent 
must be paid without demand.

     Lessee shall pay to Lessor upon the execution of this Lease Three 
Thousand Seven Hundred Fifty and 00/100 ($3,750.00) Dollars, which Lessor
shall credit Lessee for the first month's rent, to be adjusted if the 
square footage is adjusted as provided in this Lease, and if pro-rated 
due to the Commencement Date falling on a date later than the first day 
of the month, the balance to be applied to the second month's rent (which
pro rata portion shall be applicable to any Additional Rent).

  2

     4.2     This Lease is a triple net lease and during the Term and 
any Renewal Period the Lessee shall pay the Additional Rent described in 
Section 4.3.

     4.3     Additional Rent
             ---------------

          (i)    The Lessee shall pay as additional rent above the Rent 
("Additional Rent") (i) the lesser of ____% ("Lessee's Proportionate 
Share") for all exterior common area maintenance expenses attributable 
to the operation and maintenance of the Complex exclusive of electricity.
Lessor will connect 15% of the outdoor lighting for the new Building in 
which the Space is located directly to Lessee's meter and there will be 
no other electric utility charges to Lessee.  Lessor shall provide item-
ization to Lessee of the exterior common area maintenance expenses.  
Lessee's Proportionate Share is determined by dividing the square 
footage of the Space by the square footage of the Complex.  Any addi-
tions to the Complex shall proportionately reduce Lessee's Propor-
tionate Share.  Lessor shall promptly notify Lessee of any such 
additions and the new computation of Lessee's Proportionate Share.

          (ii)    With respect to each fiscal tax year or portion thereof
during the Term, the Lessee shall pay to the Lessor, as Additional Rent 
any real estate taxes, levies and special assessments assessed by any 
governmental authority only with respect to the Space.  Should any such 
assessment be provided upon the Building or Complex rather than directly 
for the Space, then Lessee shall pay Lessee's Proportionate Share of 
Lessor's interest in the Complex.  The payment of Additional Rent shall 
be pro-rated should the Lease or any renewal thereof terminate before the
end of any fiscal year.  Lessee shall make such tax payments semi-annually
or on a quarterly basis, as determined by the billing method used by the 
Borough of Chambersburg, within twenty (20) days of written notice from 
Lessor that such taxes are payable by Lessor together with the written 
assessment and tax bill.

     Subject to the provisions of Section 4.1 if any installment of Rent 
or Additional Rent is not paid within 10 days of its due date then Lessor
may assess a late charge of five (5%) percent of the total amount of Rent
or Additional Rent then due until the date of payment, which charge shall
be immediately due and payable as further Additional Rent.

     4.4     Security Deposit
             ----------------

     No security deposit required.  [B.P./C.S.P.]

     Lessee shall pay, directly to the utility company, promptly when 
due, all bills for water, sewer, electricity, heat and air conditioning 
and all other utilities that are furnished to the Space and separately 
billed and metered.

     Lessor shall have no obligation to provide utilities or equipment 
within the Space except for those utilities that are provided as of the 
Commencement Date of this Lease.  In the event Lessee requires addi-
tional utilities or equipment, the installation and maintenance thereof 
shall be at Lessee's sole obligation, provided that such installation 
shall be subject to Lessor's written consent which shall not be un-
reasonably withheld or delayed.

     Lessor shall not be liable to Lessee for any interruption of or 
failure to provide electrical service, heating, air conditioning, or 
water, or other utility service which is due to any energy shortage, 
power failure, or other cause beyond the control of Lessor, or is 
required in order to enable Lessor to perform required and necessary

trol with Lessee, or to any corporation resulting from the merger or 
consolidation with Lessee, or to any person or entity which acquires

subletting or assignment shall terminate from that time on any and all 
liabilities and obligations of Lessee to pay rent or perform under the

deemed consent to any subsequent assignment or subletting.


                    9.  RESPONSIBILITY OF LESSEE
                        ------------------------

     All damages or injuries done to the Space by Lessee and/or Lessee's 
servants, agents, employees, patients, and individuals for whom Lessee is
responsible shall be repaired by Lessee at its expense, exclusive of 
ordinary wear and tear, or except as the result, directly or indirectly, 
of Lessor's failure to maintain the Building and the Space in accordance 
with the provisions of this Lease, or except for the negligence of Lessor,
its tenants and/or their respective servants, agents, invitees or em-
ployees.  Lessee covenants and agrees to make such repairs upon thirty 
(30) days' written notice given to Lessee by 

  6

Lessor, and if Lessee shall thereafter neglect to make said repairs or 
commence to timely make the same, Lessor shall have the right to make 
such repairs at the reasonable expense and cost of Lessee, provided 
Lessor gives Lessee thirty (30) days written notice that Lessor is going 
to cure the damage or injury and charge the same to Lessee, and the 
amount thereof may be collected as Additional Rent accruing for the month
following the date of said repair.

                       10.  FIRE OR CASUALTY
                            ----------------

     In the event that the Building or the Space shall be totally or 
substantially damaged by fire or other casualty or happening, to the 
extent that the business of the Lessee cannot reasonably be conducted 
therein and if such damage cannot be or is not repaired, restored, or 
rebuilt by the Lessor, as the case may be, to substantially the same 
condition as it was immediately prior to such damage or destruction 
within three (3) months after such damage, then either the Lessor or 
Lessee shall have the option of terminating this Lease by written notice
delivered to the other party within thirty (30) days following such 
failure to rebuild; in either event Lessee shall immediately vacate 
and surrender possession of the Space to Lessor.  If neither Lessee nor 
Lessor elects to terminate this Lease, or if the Building or the Space 
is not damaged to the extent that the damage unreasonably interferes 
with Lessee's Use, Lessor shall proceed with said repairs with all 
reasonable diligence, but in no event shall the repairs exceed ninety 
(90) days.  The rent payable hereunder shall entirely abate in case the 
Space or the Building is substantially destroyed or so damaged as to 
render the Space untenantable or not useable or convenient or in a con-
dition for patients of Lessee noting the Use of the Space, or abate 
proportionately according to the extent of the injury or damage sus-
tained by the Building or the Space, if such is not substantially 
destroyed or is rendered partially untenantable, until the Building 
and the Space shall have been restored, repaired, or rebuilt and put 
in proper condition for the Use and occupancy of Lessee.  Lessor agrees 
to institute such repairs immediately after such damage and to complete 
the same with due diligence and within a reasonable time as provided in 
this Lease.

                       11.  SUBORDINATION
                            -------------

     This Lease shall be subject and subordinate to any and all mortgages,
deeds of trust and other instruments in the nature of a mortgage, which 
now or at any time hereafter, become a lien or liens on the Building.  In 
confirmation of such subordination, Lessee shall, when requested by 
Lessor or any mortgagee or their respective successors, promptly execute
and deliver such written instruments as shall be necessary to show, 
acknowledge or confirm the subordination of this Lease to said mortgages,
deeds of trust or other such instruments in the nature of a mortgage.  
If Lessee fully performs its obligations under the Lease then, with 
respect to any mortgage or instrument now or hereafter becoming a lien 
or liens on the Building, Lessee's obligation to subordinate to such 
mortgage or other instrument shall be conditioned upon the mortgagee 
agreeing not to unreasonably disturb or interfere with Lessee's rights, 
Lessee's quiet enjoyment or with Lessee's possession of the Space.  
Notwithstanding the foregoing, Lessee shall not unreasonably withhold or
delay executing a subordination agreement if the lender presents a 
standard subordination and non-interference agreement utilized industry
wide.

                  12.  LESSOR'S ACCESS AND INSPECTION
                       ------------------------------

     The Lessor, its employees, agents and servants may at reasonable 
times, with reasonable notice, or in emergency situations, enter all 
parts of the Space; to inspect the same; to enforce or carry out any 
provision of the Lease; to make repairs and alterations as Lessor 
should elect to do; and within 120 days of expiration of the Term or 
Renewal Term, to show the Leased Premises to others.

  7

                           13.  CONDEMNATION
                                ------------

     If any part of the Space or the Building should be taken for any 
public or quasi-public use under governmental law, ordinance, or regu-
lation, or by right of eminent domain, or by private purchase in lieu 
thereof (a "Taking" or "Taken"), and the Taking would prevent or 
materially interfere with Lessee's use of the Space or in Lessor's 
judgment would materially interfere with or impair its ownership or 
operation of the Building, then upon written notice by Lessor this Lease
shall terminate and the Rent and Additional Rent shall be apportioned as 
of said date.  If part of the Space shall be Taken, and this Lease is not
terminated as provided above, the Rent and Additional Rent payable here-
under during the unexpired Term shall be reduced to such extent as may 
be fair and reasonable under the circumstances.  In the event of any 
such Taking, Lessor shall be entitled to receive the entire price or 
award from any such Taking without any payment to Lessee and Lessee 
hereby assigns to Lessor Lessee's interest, if any, in such award.  
Lessee shall have the right, to the extent that same shall not diminish 
Lessor's award, to make a separate claim against the condemning 
authority (but not Lessor) for such compensation as may be separately 
awarded or recoverable by Lessee for moving expenses and damage to 
Lessee's trade fixtures, if a separate award for such items is made to 
Lessee.

                        14.  INDEMNIFICATION
                             ---------------

     Except for the negligence of Lessor, its agents, employees or con-
tractors, and to the extent permitted by law, Lessee agrees to indemnify,
defend and hold harmless Lessor, and Lessor's agents, employees and con-
tractors, from and against any and all losses, liabilities, damages, 
costs and expenses (including reasonable attorneys' fees) resulting 
from claims by third parties for injuries to any person and damage to 
or theft or misappropriation or loss of property occurring in or about 
the Building and arising from the use and occupancy of the Space or 
from any activity, work, or thing done, permitted or suffered by Lessee 
or due to any other act or omission of Lessee, its subtenants, assignees,
invitees, employees, contractors and agents in or about the Space.  The 
furnishing of insurance required hereunder shall not be deemed to limit 
Lessee's obligations under this Section 14.

                         15.  EVENTS OF DEFAULT
                              -----------------

     Each of the following events shall be an event of default ("Event 
of Default") by Lessee under this Lease:

other payment required herein when due, and such failure shall continue 
for a period of 10 days from the date such payment was due.

          (ii)    Lessee shall (A) make a general assignment for the 
benefit of creditors; (B) commence any case, proceeding or other action 
seeking to have an order for relief entered on its behalf as a debtor or

          (iii)   Any insurance required to be maintained by Lessee pur-
suant to this Lease shall be canceled or terminated or shall expire or

          (iv)    Lessee shall not occupy or shall vacate the Space or 
shall fail to continuously operate its business at the Space for the Use
during the Term or Renewal Period, if applicable, whether or not Lessee 
is in monetary or other default under this Lease.

          (v)     Lessee shall attempt or there shall occur any assign-
ment, subleasing or other transfer of Lessee's interest in or with 
respect to this Lease except as otherwise permitted in this Lease.

          (vi)    Lessee shall fail to discharge any lien placed upon the
Building in violation of this Lease within 30 days after any such lien or
encumbrance is filed against the Building.

          (vii)   Lessee shall fail to materially comply with any pro-
vision of this Lease other than those specifically referred to in this 
Section 15, and except as otherwise expressly provided herein, such 
default shall continue for more than 30 days after Lessor shall have 
given Lessee written notice of such default.

                     16.  REMEDIES OF LESSOR
                          ------------------

     Upon each occurrence of an Event of Default and so long as such 
Event of Default shall be continuing, Lessor may at any time thereafter 
at its election terminate this Lease or Lessee's right of possession (but
Lessee shall remain liable as hereinafter provided), and/or pursue any 
other remedies at law or in equity.  Upon the termination of this Lease 
or termination of Lessee's right of possession, it shall be lawful for 
Lessor, to re-enter the Space by summary dispossession proceedings or any
other action or proceeding authorized by law and to remove Lessee and all
persons and property therefrom.  If Lessor re-enters the Space, Lessor 
shall have the right to keep in place and use, or remove and store, all 
of the furniture, fixtures and equipment at the Space.

     If Lessor terminates this Lease, Lessor may recover from Lessee the 
sum of: all Rent, Additional Rent and all other amounts accrued hereunder
to the date of such termination; the cost of reletting the whole or any 
part of the Space, including without limitation brokerage fees and/or 
leasing commissions incurred by Lessor, and costs of removing and storing
Lessee's or any other occupant's property, repairing, altering, re-
modeling, or otherwise putting the Space into condition acceptable to 
a new tenant or tenants, and all reasonable expenses incurred by Lessor 
in pursuing its remedies, including reasonable attorneys' fees and court 
costs.

     If Lessor terminates Lessor's right of possession (but not this 
Lease), Lessor shall relet the Space for rent and upon such terms as 
shall be satisfactory to Lessor without thereby releasing Lessee from 
any liability hereunder and without demand or notice of any kind to 
Lessee.  For the purpose of such reletting Lessor is authorized to make 
any repairs, changes, alterations, or additions in or to the Space as 
Lessor deems reasonably necessary or desirable.  If the Space is not 
relet, then Lessee shall pay to Lessor as damages a sum equal to the 
amount of rental reserved in this Lease for such period or periods, plus
the cost of recovering possession of the Space (including reasonable 
attorney's fees and costs of suit), the unpaid Rent, Additional Rent and 
other amounts accrued hereunder at the time of repossession, and the 
costs incurred in any attempt by Lessor to relet the Space.  If the 
Space is relet and a sufficient sum shall not be realized from such 
reletting [after first deducting therefrom, for retention by Lessor, 
the unpaid Rent, Additional Rent and other amounts accrued hereunder at 
the time of reletting, the cost of recovering possession (including 
reasonable attorneys' fees and costs of suit), all of the costs and 
expenses of repairs, changes, alterations, and additions, the expense 
of such reletting (including without limitation brokerage fees and 
leasing commissions) and the cost of collection of the Rent and Addi-
tional Rent accruing therefrom] to satisfy the Rent provided for in 
this Lease to be paid, then Lessee shall immediately satisfy and pay 
any such deficiency.  Any such payments due Lessor shall be made upon 
demand therefor from time to time and Lessee agrees that Lessor may file
suit to recover any sums falling due from time to 

  9

time.  Notwithstanding any such reletting without termination, Lessor 
may at any time thereafter elect in writing to terminate this Lease for 
such previous breach.

     Exercise by Lessor of any one or more remedies hereunder granted or 
otherwise available shall not be deemed to be an acceptance of surrender 
of the Space and/or a termination of this Lease by Lessor, whether by 
agreement or by operation of law, it being understood that such surrender
and/or termination can be effected only by the written agreement of Lessor
and Lessee.  The failure of Lessor at any time to enforce its rights under
this Lease strictly in accordance with same shall not be construed as 
having created a custom in any way or manner contrary to the specific 
terms, provisions, and covenants of this Lease or as having modified the 
same.  Lessee and Lessor further agree that forbearance or waiver by 
Lessor to enforce its rights pursuant to this Lease or at law or in 
equity, shall not be a waiver of Lessor's right to enforce one or more 
of its rights in connection with any subsequent Event of Default.  No 
waiver by Lessor of any provision of this Lease shall be deemed to have 
been made unless expressed in writing and signed by Lessor.  To the 
greatest extent permitted by law, Lessee waives all right of redemption 
in case Lessee shall be dispossessed by a judgment or by warrant of any 
court or judge.

                       17.  REMEDIES OF LESSEE
                            ------------------

     In the event of a default under the terms, covenants or conditions 
of this Lease on the part of the Lessor which shall include but not be 
limited to unreasonably withholding consents, failure to maintain facil-
ities for the introduction of water, gas, and electric into the Space, 
failure to maintain the Building and the Space as required herein, 
failure to use due care with respect to the persons and property of 
Lessee, failure of Lessor's warranties as to the good operating condi-
tion of the services to the Space, and otherwise interfering with, 
whether negligently or intentionally, the business of Lessee and its 
peaceable and quiet enjoyment of the Space for the Term or any Renewal
Term, Lessee shall notify Lessor in writing of said default and Lessor 
shall have thirty (30) days to cure or commence to cure said default; 
provided that if the nature of the default is such that it cannot be 
reasonably cured within said thirty (30) days, Lessor shall not be 
deemed to be in default if it shall commence performance within said 
thirty (30) day period and diligently proceeds to so cure the default 
thereafter.  If Lessor shall not cure or commence to cure the said 
default within the thirty (30) day period, Lessee has the option to 
either terminate this Lease and vacate the Space immediately without any
further liability under the Lease and take whatever other lawful 
remedies that may be available to it upon such default, or cure the 
default and at Lessee's option deduct reasonable costs and expenses 
for such cure from Rent or Additional Rent or any other amounts accrued
hereunder due, or otherwise be immediately reimbursed by Lessor.

     Should there be a need to make any emergency repairs which were 
otherwise the responsibility of the Lessor as provided in this Lease, but
due to the emergent circumstances, Lessee makes such repairs, the cost 
thereof shall be a deduction from the Rent and Additional Rent accruing 
for the month following the date of such repair.

                           18.  INSURANCE
                                ---------

          (i)     Lessee, at its cost, shall maintain a policy of Com-
bined Single Limit Bodily Injury and Property Damage Insurance during 
the Term and any Renewal Term such insurance to provide protection in 
the amount of One Million ($1,000,000) Dollars combined single limit, 
insuring Lessor and Lessee against any liability arising out of and in 
connection with Lessee's Use or occupancy of the Space. Lessee should 
also obtain and maintain a policy or policies of insurance covering loss
or damage to the Space, providing protection against all perils included 
within the classification of fire, extended coverage, vandalism, mali-
cious mischief, flood (in the event such is required by a lender having
a lien on the Building), and special extended perils ("all risk" as 
such term is used in the insurance industry).

  10

          (ii)    Lessor shall obtain and maintain insurance on the 
Building, primarily a policy of Combined Single Limit Bodily Injury and 
Property Damage Insurance insuring against any liability arising out of 
the ownership or maintenance of the Building and all areas appurtenant 
thereto in an amount not less than combined single limit of One Million 
($1,000,000) Dollars.

          (iii)   Insurance required hereunder shall be placed with rep-
utable insurance companies.  Each party shall deliver to the other 
copies of policies of liability insurance required under this Section 
18 or certificates evidencing the existence and amounts of such insur-
ance.  No such policy shall be cancelable or subject to reduction of 
coverage or other modification except after thirty (30) day's prior 
written notice to Lessor or Lessee, as the case may be.  Lessor and 
Lessee shall, at least thirty (30) days prior to the expiration of such
policies, furnish the other party with renewals or "binders" thereof, 
or the other party, after ten (10) days written notice, may order such 
insurance, provided such is during and for the Term or any Renewal Term,
and charge the cost thereof to the non-renewing party which amount shall
be payable upon demand.  Lessor and Lessee shall not do or permit to be 
done anything which shall invalidate the insurance policies referred to 
in this Section 18.

          (iv)    Lessee and Lessor each hereby release and relieve the 
other (which includes the other party's employees, agents, officers, 
directors and shareholders) from any liability, whether for negligence 
or otherwise, in connection with loss covered by any insurance policies
which the releasor carries with respect to the Building and/or the Space
or any interest or property therein or thereon, but only to the extent 
that such loss is collected under said insurance policies. Such release 
is also conditioned upon the inclusion in the policy of a provision 
whereby any such release does not adversely affect such policy or pre-
judice any right of the releasor to recover thereunder.  Each party's 
insurance policies shall include such a provision so long as it is 
obtainable without extra cost.

                         19.  QUIET ENJOYMENT
                              ---------------

     Lessor, covenants and agrees that Lessee, upon paying said rent 
and performing the covenants of this Lease, on its part to be performed,
shall and may peaceably and quietly have, hold and enjoy the Space and 
common areas, including but not limited to parking areas, sidewalk 
entrances and exits of the Building and the Complex, for the Term and 
any Renewal Term.

                          20.  HAZARDOUS WASTE
                               ---------------

     Lessee shall not dump, flush or in any way introduce any hazardous
substances or any other toxic substances into the septic, sewage or 
other waste disposal system serving the Space, Building and Complex.  
Lessee and Lessor shall not dispose of any hazardous or toxic sub-
stances or wastes in or on the Space, Building or Complex nor generate,
store, use or dispose of any hazardous or toxic substances, except as 
may be permitted by applicable law, therein or thereon.  To the best 
of Lessor's knowledge and belief, Lessor states that it has not gen-
erated any hazardous waste in or upon the Space, the Building or the 
Complex, nor does it have knowledge that any other lessee of the 
property has done the same.  Lessee shall indemnify, save and hold 
Lessor harmless from and against all costs, fees, expenses, including 
reasonable attorneys' fees, losses and damages resulting from or arising
out of the generation, storage, use or disposal of hazardous wastes by 
Lessee on or about the Space, the Building and the Complex, including 
the transport or leaching of any hazardous wastes from the Space, 
Building and Complex.  Lessee shall not make any use of the Space, 
Building or Complex which is improper, offensive or contrary to any 
law or ordinance or which will invalidate any of the Lessor's in-
surance.

Lessee of their obligations hereunder have been duly authorized by their
respective boards of directors and/or partners, as the case may be, and 
this Lease is a binding and enforceable Lease of Lessor and Lessee 
according to its terms.  The execution, delivery and performance of this
Lease by Lessor and Lessee will not result in any violation of and will 
not conflict with, or result in any breach of any of the terms of or con-
stitute a default under, or constitute an event which with notice or the
passage of time or both would constitute a default under, any provision 
of any law to which Lessor or Lessee is subject, the partnership agree-
ment of Lessor, or the articles of incorporation, and by-laws of the 
Lessee, or any mortgage, indenture, agreement, instrument, judgment, 
decree, or rule or resolution or other restriction to which Lessor or 
Lessee is bound.  The representations as contained herein are only made
by Lessor and Lessee as to their own corporate acts, articles of incor-
poration, by-laws and/or partnership agreements, as the case may be, 
and their respective related agreements and regulations and neither 
makes any representations as to the others acts, articles of incorpo-
ration, by-laws, partnership agreements, as the case may be, and 
related agreements and regulations.

     No action, approval, consent or authorization, including but not 
limited to any action, approval or consent of any shareholder, note 
holder, partner, or order of any court or governmental agency, com-
mission, board, bureau or instrumentality, otherwise than as specif-
ically provided in this Lease, is necessary in order to constitute
