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

     Lessee shall accept the Space in its condition as of the commence-
ment date of the Term, subject to all applicable laws, ordinances,

tation or warranty as to the suitability of the Space for the conduct

Space is suitable for Lessee's intended purposes and Use.  Except as 
provided in Section 6, in no event shall Lessor have any obligation for
any defects in the Space or any limitation on its Use.  The taking of 
possession of the Space shall be conclusive evidence that Lessee 
accepts the Space and that the Space was in good condition at the time 
possession was taken except for items that are Lessor's responsibility 
under Section 6 and any punchlist items agreed to in writing by Lessor 
and Lessee.

     3.2  Possession

Space to and comply with all the requirements of the appropriate govern-
mental officials, agencies, commissions and boards having jurisdiction 
over the Use of the Space, including but not limited to the Americans

best efforts to assist Lessee in submitting and obtaining any such 
applications and approvals.  If Lessee is unable to obtain the 
appropriate permits, variances, licenses and/or other approvals for the 
Use of the Space, Lessor may, at its option but is not otherwise 
required, obtain such Government Compliance, and Lessee will use its 
best efforts to assist Lessor in obtaining such compliance, and all 
costs and expenses to effect such Government Compliance to be charged 
to Lessee as Additional Rent as defined in Section 4.2 accruing for 
the month following effectuation of such compliance; or if Lessor 
does not exercise its option to obtain the Government Compliance,

Lessee with written notice of such delivery, Lessee hereby releases 
Lessor, herein named, of any and all liability with respect to the 
security deposit, its

grantee or transferee.  It is further understood that this provision 
shall also apply to subsequent grantees and transferees.

or is required in order to enable Lessor to perform required and 
necessary maintenance or repairs within the Building; nor shall any 
non-supply or change in supply of any utility service in any way 
effect the tenancy or relieve Lessee of any obligation under the terms 
of this Lease.

     10.3  Discharge of Liability.  In consideration of securing this 
           ----------------------
Lease at the above-stated Rent, Lessee does hereby release and discharge 
the Lessor and its Agents, and said Lessor's successors and/or assigns, 
from any and all liability by reason of any injury, loss and/or damage 
to any person or property, caused by any fire, the breaking, bursting, 
stoppage and/or leakage of any water pipe, gas pipe, sewer, basin, water
closet, steam pipe, and drain in any part or portion of the Space and/or
any part or portion of the Building, and from all liability for any and 
all injury, loss and/or damage caused by the water, gas, steam, waste, 
and contents of said water pipes, gas pipes, steam pipes, sewers, 
basins, water closets, and drains or the elements or from any kind of 
injury, loss, and/or damage which may arise from any other cause in the 
Space, on the premises or in the Building.

                       11.  EVENTS OF DEFAULT
                            -----------------

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

          (i)    Lessee shall fail to pay any installment of Rent or any
other payment required herein when due, and such failure shall continue 
for a period of five 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
to adjudicate it a bankrupt or insolvent, or seeking reorganization, 
arrangement, adjustment, liquidation, dissolution or composition of it 
or its debts or seeking appointment of a receiver, trustee, custodian 
or other similar official for it or for all or of any substantial part 
of its property (collectively a 

<PAGE>  8

"proceeding for relief"); (C) become the subject to any proceeding for 
relief which is not dismissed within 60 days of its filing or entry; or
(D) be dissolved or otherwise fail to maintain its legal existence.

          (iii)  Any insurance required to be maintained by Lessee 
pursuant to this lease shall be canceled or terminated or shall expire 
or shall be materially reduced or changed, except, in each case, as 
permitted in this Lease.

          (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 Space or the Building in violation of this Lease within 30 days 
after any such lien or encumbrance is filed against the Space or the 
Building.

          (vii)  Lessee shall fail to comply with any provision of this
Lease other than those specifically referred to in this Section 11, 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.

                      12.  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 and 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 and 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.

     Upon Lessor's termination of 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, remodeling, 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 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 
Additional 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.

     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, 

<PAGE>  9

whether by agreement or by operation of law.  Any law, usage, or custom 
to the contrary notwithstanding, Lessor shall have the right at all times
to enforce the provisions of this Lease in strict accordance with the 
terms hereof; and 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 default.  A receipt by 
Lessor of rent or other payment with knowledge of the breach of any term 
or covenant of this Lease shall not be deemed a waiver of such breach, an
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 the service of notice of 
Lessor's intention to re-enter as provided for in any statute, or to 
institute legal proceedings to that end, and also waives all right of 
redemption in case Lessee shall be dispossessed by a judgment or by 
warrant of any court or judge.  Any reletting of the Space shall be on 
such terms and conditions as Lessor in its sole discretion may determine 
(including without limitation a term different than the remaining Term, 
rental concessions, alterations and repair of the Space, lease of less 
than the entire Space to any tenant and leasing any or all other portions
of the Building before reletting the Space).  Lessor shall not be liable,
nor shall Lessee's obligations hereunder be diminished because of, 
Lessor's failure to relet the Space or collect Rent due in respect of 
such reletting.

                      13.  REMEDIES OF LESSEE
                           ------------------

     In the event of a default under the terms, covenants or conditions 
of this Lease on the part of the Lessor, 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 may not terminate this Lease and vacate the Space, but rather 
may only cure the default and deduct reasonable costs and expenses for
such cure from Rent or Additional Rent or any other amounts accrued 
hereunder due.

     All obligations of Lessee hereunder shall be construed as covenants,
not conditions; and, except as may be otherwise expressly provided in 
this Lease, Lessee may not terminate this Lease for breach of Lessor's 
obligations hereunder.  All obligations of Lessor under this Lease will
be binding upon Lessor only during the period of its ownership of the 
Building and not thereafter.  The term "Lessor" in this lease shall 
mean only the owner, for the time being of the Building, and in the 
event of the transfer by such owner of its interest in the Building, 
such owner shall thereupon be released and discharged from all obliga-
tions of Lessor thereafter accruing, but such obligations shall be 
binding during the Term upon each new owner for the duration of such 
owner's ownership.  Any liability of Lessor under this Lease shall be 
limited solely to its interest in the Building, and in no event shall 
any personal liability be asserted against Lessor in connection with 
this Lease nor shall any recourse be had to any other property or 
assets of Lessor.

                           14.  INSURANCE
                                ---------

     14.1  Lessee Insurance.  Lessee, at its cost, shall maintain a 
           ----------------
policy of Combined Single Limit Bodily Injury and Property Damage 
Insurance during the Term and any Renewal Period, 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 

<PAGE>  10

damage to the Space, providing protection against all perils included 
within the classification of fire, extended coverage, vandalism, 
malicious 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).  Lessee shall also 
maintain workmen's compensation insurance with no less than the minimum
limits required by law.  The commercial liability insurance policies 
shall name Lessor as an additional insured, insure on an occurrence 
and not a claims-made basis, contain a hostile fire endorsement and a 
contractual liability endorsement and provide primary coverage to 
Lessor (any policy issued to Lessor providing duplicate or similar 
coverage shall be deemed in excess over Lessee's policies).

     14.2  Lessor Insurance.  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.  All such insurance shall 
be included as part of the CAM charges to Lessee pursuant to Section 
4.2 hereof.

     14.3  Reputable Carriers.  Insurance required hereunder shall be 
           ------------------
placed with reputable insurance companies.  Each party shall deliver to 
the other copies of policies of liability insurance required under this 
Section 14 or certificates evidencing the existence and amounts of such 
insurance.  No such policy shall be cancelable or subject to reduction 
of coverage or other modification except after thirty (30) days 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 
Period, 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 14.

     14.4  Subrogation.  Lessee and Lessor each hereby release and 
           -----------
relieve the other (which includes the other party's Agents) 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 prejudice 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.

     14.5  Business Interruption.  Lessor and Lessor's Agents shall not
           ---------------------
be liable for, and Lessee hereby waives all claims against such parties 
for, business interruption and losses occasioned thereby sustained by 
Lessee or any person claiming through Lessee resulting from any accident
or occurrence in or upon the Space or the Building from any cause what-
soever, including without limitation, damage caused in whole or in part,
directly or indirectly, by the negligence of Lessor or Lessor's Agents.

                     15.  FIRE OR CASUALTY
                          ----------------

     15.1  Substantial Damage; Rent Abatement.  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 not later than 
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 

<PAGE>  11

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 condition for 
its Use, or abate proportionately according to the extent of the injury 
or damage sustained by the Building or the Space, if such is not sub-
stantially 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.

     15.2  Damage for Interruption of Use.  Lessor shall not be liable 
           ------------------------------
for any damage, compensation or claim by reason of inconvenience of 
annoyance arising from the necessity of making repairs, alterations 
and/or additions to any portion of the Space, the interruption in the 
Use of the Space, or the termination of this Lease by reason of the 
destruction of the Space.

                  16.  ENVIRONMENTAL REQUIREMENTS
                       --------------------------

     Lessee shall not permit or cause any party to bring any Hazardous 
Material into the Space or transport, store, use, generate, manufacture 
or release any Hazardous Material in or about the Space without Lessor's
prior written consent.  Lessee, at its sole cost and expense, shall 
operate its business in the Space in strict compliance with all Environ-
mental Requirements and shall remediate in a manner satisfactory to 
Lessor any Hazardous Materials released on or from the Building by 
Lessee and/or its Agents.  Lessee shall complete and certify to dis-
closure statements as requested by Lessor from time to time relating 
to Lessee's transportation, storage, use, generation, manufacture, or 
release of Hazardous Materials on or about the Space.  The term 
"Environmental Requirements" means all applicable present and future 
statutes, regulations, ordinances, rules, codes, judgments, orders or 
other similar enactments of any governmental authority or agency 
regulating or relating to health, safety, or environmental conditions 
on, under or about the Space or the environment, including without 
limitation, the following: the Comprehensive Environmental Response, 
Compensation and Liability Act; the Resource Conservation and Recovery 
Act; and all state and local counterparts thereto, and any regulations 
or policies promulgated or issued thereunder.  The term "Hazardous 
Materials" means and includes any substance, material, waste, pollutant,
or contaminant listed or defined as hazardous or toxic, under any 
Environmental Requirements, asbestos and petroleum, including crude oil
or any fraction thereof, natural gas, or synthetic gas usable for fuel 
(or mixtures of natural gas and such synthetic gas).  As defined in 
Environmental Requirements, Lessee is and shall be deemed to be the 
"operator" of Lessee's "facility" and the "owner" of all Hazardous 
Materials brought into the space by Lessee and its Agents, and the 
wastes, by-products, or residues generated, resulting, or produced 
therefrom.

     Lessee shall indemnify, defend, and hold Lessor harmless from and 
against any and all losses (including, without limitation, diminution 
in value of the Space or the Building and loss of rental income from 
the Building), claims, demands, actions, suits, damages (including, 
without limitation, punitive damages), expenses (including, without 
limitation, remediation, removal, repair, corrective action, or 
cleanup expenses), and costs (including, without limitation, actual 
attorneys' fees, consultant fees or expert fees and including, without
limitation, removal or management of any asbestos brought into the 
Space or disturbed in breach of the requirements of this Section 16, 
regardless of whether such removal or management is required by law) 
which are brought or recoverable against, or suffered or incurred by 
Lessor as a result of any release of Hazardous Materials for which 
Lessee is obligated to remediate as provided above or any other breach
of the requirements under this Section 16 by Lessee and its Agents, 
regardless of whether Lessee had knowledge of such noncompliance.  The
obligations of Lessee under this Section 16 shall survive any termina-
tion of this Lease.

<PAGE>  12

     Lessor shall have access to, and a right to perform inspections and
tests of, the Space to determine Lessee's compliance with Environmental 
Requirements, its obligations under this Section 16, or the environ-
mental condition of the Space.  Access shall be granted to Lessor upon 
Lessor's prior notice to Lessee and at such times so as to minimize, so
far as may be reasonable under the circumstances, any disturbance to 
Lessee's operations.  Such inspections and tests shall be conducted at 
Lessor's expense, unless such inspections or tests reveal that Lessee 
has not complied with any Environmental Requirement, in which case 
Lessee shall reimburse Lessor for the reasonable cost of such inspection
and tests.  Lessor's receipt of or satisfaction with any environmental 
assessment in no way waives any rights that Lessor holds against Lessee.

                          17.  SURRENDER
                               ---------

     Upon expiration or earlier termination of the Lease in accordance 
with its terms, Lessee shall surrender the Space to Lessor in the same 
condition as received, broom clean, ordinary wear and tear and casualty
loss and condemnation covered by Sections 15 and 18 excepted.  Any 
trade fixtures, Lessee-made alterations and property not so removed 
by Lessee as permitted or required herein shall be deemed abandoned 
and may be stored, removed, and disposed of by Lessor at Lessee's 
expense, and Lessee waives all claims against Lessor for any damages 
resulting from Lessor's retention and disposition of such property.  
All obligations of Lessee hereunder not fully performed as of the 
termination of the Lease shall survive the termination of the Lease, 
including without limitation, indemnity obligations, payment obliga-
tions with respect to Rent, and all obligations concerning the 
condition and repair of the Space.

                       18.  CONDEMNATION
                            ------------

     If any part of the Space should be taken or condemned for a public
or quasi-public use, and a part thereof remains which is susceptible 
for the Use intended, this Lease shall, as to the part so taken, 
terminate as of the date title shall vest in the condemnor, and the 
Rent payable hereunder shall be adjusted so that the Lessee shall be 
required to pay for the remainder of the Term only such portion of such 
Rent at the value of the part remaining after the condemnation bears to 
the value of the entire Space at the date of condemnation; but in such 
event Lessor shall have the option to terminate this Lease as of the 
date when title to the part so condemned vests in the condemnor.  If all
the Space, or such part thereof be taken or condemned so that there 
does not remain a portion susceptible for occupation hereunder, this 
Lease shall thereupon terminate.  Whether or not a portion of the Space
is susceptible for the Use intended shall be determined by arbitration 
if the parties cannot otherwise agree on said portion.  If a part of all
of the Space be taken or condemned, all compensation, except as otherwise
provided in this Section 18, awarded upon such condemnation or taking 
shall, go to the Lessor and the Lessee shall have no claim thereto.

                19.  SUBORDINATION; ASSIGNMENT BY LESSOR
                     -----------------------------------

     The rights and interest of Lessee under this Lease shall be subject
and subordinate to any mortgage that may be placed upon the Space and to
any and all advances to be made thereunder, and to the interest thereon,
and all renewals, replacements, and extensions thereof.  Whether this 
Lease is dated prior to or subsequent to the date of said mortgage, 
Lessee shall execute and deliver whatever instruments may be required 
for such purposes and in the event Lessee fails to do so within ten (10)
days after demand in writing, Lessee does hereby make, constitute and 
irrevocably appoint Lessor as its attorney-in-fact and in its name, 
place and stead so to do.  Lessor may assign its interest in this Lease 
or any part thereof, and such assignee shall thereupon be deemed Lessor 
hereunder.

<PAGE>  13

                      20.  QUIET ENJOYMENT
                           ---------------

     Lessee, upon paying the Rent and performing the covenants of this 
Lease, on its part to be performed, shall and may peaceably and quietly
enjoy the Space for the Term and any duly authorized Renewal Period, 
against any person claiming by, through or under the Lessor.

                       21.  SPACE PREPARATION
                            -----------------

     It is understood that the Space shall be rented by the Lessee on an 
"as is" basis, and the only Space preparation work that shall be done 
shall be the work as outlined on Exhibit A attached to and made a part 
of this Lease.

                       22.  AUTHORIZATON
                            ------------

     Lessor and Lessee each has all the requisite right, power, legal 
capacity and authority, corporate and otherwise, to enter into this 
Lease and to assume and perform their respective obligations hereunder.
The execution and delivery of this Lease and the performance by Lessor 
and 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 constitute 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, any 
partnership agreement, the articles of incorporation, and/or by-laws of 
any party, 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 
incorporation, 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 other's acts, articles of incorpora-
tion, 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, 
commission, board, bureau or instrumentality, otherwise than as 
specifically provided in this Lease, is necessary in order to constitute
this Lease as a valid, binding and enforceable obligation of the parties
hereto in accordance with its terms.

                     23.  ESTOPPEL CERTIFICATES
                          ---------------------

     Lessee agrees, from time to time, within 10 days after request of 
Lessor, to execute and deliver to Lessor, or Lessor's designee, any 
estoppel certificate requested by Lessor, stating that this Lease is 
in full force and effect, the date to which Rent has been paid, that 
Lessor is not in default hereunder (or specifying in detail the nature
of Lessor's default), the termination date of this Lease and such other
matters pertaining to this Lease as may be requested by Lessor.  
Lessee's obligation to furnish each estoppel certificate in a timely 
fashion is a material inducement to Lessor's execution of this Lease.  
No cure or grace period provided in this Lease shall apply to Lessee's 
obligations to timely deliver an estoppel certificate.  Lessee hereby 
irrevocably appoints Lessor as its attorney-in-fact to execute on its 
behalf and in its name any such estoppel certificate if Lessee fails to
execute and deliver the estoppel certificate within 10 days after 
Lessor's written request thereof.

<PAGE>  14

                      24.  WAIVER OF JURY TRIAL
                           --------------------

     LESSEE AND LESSOR WAIVE ANY RIGHT TO TRIAL BY JURY OR TO HAVE A 
JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT,
TORT, OR OTHERWISE, BETWEEN LESSOR AND LESSEE ARISING OUT OF THIS LEASE 
OR ANY OTHER INSTRUMENT, DOCUMENT, OR AGREEMENT EXECUTED OR DELIVERED 
IN CONNECTION HEREWITH OR THE TRANSACTIONS RELATED HERETO.

                25.  LANDLORD'S LIEN/SECURITY INTEREST
                     ---------------------------------

     Lessee hereby grants Lessor a security interest, and this Lease 
constitutes a security agreement, within the meaning of and pursuant to
the Uniform Commercial Code of the state in which the Space is situated
as to all of Lessee's property situate in, or upon, or used in connec-
tion with the Space (except merchandise sold in the ordinary course of 
business) as security for all of Lessee's obligations hereunder, 
including without limitation, the obligation to pay Rent.  Such person-
alty thus encumbered includes specifically all trade and other fixtures
for the purpose of this Section 25 and inventory, equipment, contract 
rights, accounts receivable and the proceeds thereof.  In order to 
perfect such security interest, Lessee shall execute such financing 
statements and file the same at Lessee's expense at the state and 
county Uniform Commercial Code filing offices as often as Lessor in 
its discretion shall require; and Lessee hereby irrevocably appoints 
Lessor its agent for the purpose of executing and filing such financing
statements on Lessee's behalf as Lessor shall deem necessary.

                        26.  FORCE MAJEURE
                             -------------

     Neither Lessor nor Lessee shall be held responsible for delays in 
the performance of its obligations hereunder when caused by strikes,

part with Wirehead Networking Solutions, Inc. ("Lessee") for the Space 
located at 27 Miller Street, Lemoyne, Pennsylvania, John Frisch,

     THIS TENANT SUBORDINATION AGREEMENT made as of the 1 day of 
December 1998, by and between WIREHEAD NETWORK SOLUTIONS, a Pennsyl-
vania corporation (the "Tenant") and Mercantile-Safe Deposit and 
Trust Company, a Maryland banking institution (the "Bank").

     WHEREAS, the Tenant is the lessee under a certain lease (the "Lease")
dated December 21, 1998 from Dialysis Corporation of America, a Florida 
corporation (the "Landlord"), to Tenant, of certain real property, 
together with the improvements thereon, known as 27 Miller Street, 
located in Lemoyne, Cumberland County, Pennsylvania, as more particu-
larly described in the Lease (the "Premises");

                                      LEASE COMMENCEMENT DATE 1-1-1999

     WHEREAS, the Bank has made a loan to Landlord and secured said loan
by a Mortgage and Security Agreement dated November 30, 1988 on the 
Premises (the "Mortgage"); and

     WHEREAS, at the request of the Landlord and in consideration of the 
making of said loan by the Bank, the Tenant has agreed to subordinate the
Lease to the Mortgage.

     NOW, THEREFORE, THIS SUBORDINATION AGREEMENT WITNESSETH, that for 
valuable consideration, the receipt and sufficiency of which are hereby 
acknowledged, the parties hereto do hereby agree and covenant as follows:

     1.  Tenant hereby acknowledges and agrees that the Lease is and shall
be (i) subordinate to the Mortgage, and (ii) subject and inferior to the 
Mortgage.

     2.  Should the Premises be transferred to any person or party other 
than the Landlord by reason of foreclosure of or other proceedings 
brought pursuant to or under the Mortgage, Tenant shall attorn to and 
be bound to said transferee under all of the terms, covenants and con-
ditions of the Lease for the remaining balance of the term thereof and
any extensions or renewals thereof, with the same force and effect as 
if the transferee was the lessor under the Lease.

     3.  Unless Tenant is in default under the Lease, the Lease shall 
not be terminated, nor shall Tenant's use, possession or enjoyment of 
the Premises be interfered with, by reason of any foreclosure 
proceeding or other action brought pursuant to or under the Mortgage.

     4.  Each party hereto does hereby agree to execute, acknowledge and
deliver to the other such further instruments as may be necessary to 
effectuate the purposes of this subordination, attornment and non-
disturbance.
