          (A) Each  Debtor  shall  remain  liable as lessor  under its Leases to
perform all the obligations  assumed by each Debtor thereunder.  The obligations
of each  Debtor  under the  Leases  may be  performed  by  Secured  Party or any
subsequent  assignee of the Secured Party  ("Subsequent  Secured Party") without

obligated to perform any of the obligations of any Debtor under any Leases or to
file any claim or take any other  action  to  collect  or  enforce  any  payment
assigned hereunder.

         (b) Each Debtor hereby agrees (i) to perform duly and  punctually  each
of the terms, conditions and covenants contained in the Leases, and (ii) subject
to such  Debtor's  business  judgment and  reasonable  commercial  practice,  to
exercise  promptly  and  diligently  each and every  right it may have under the
Leases.

         (C) Each Debtor does hereby  warrant and represent  that all Leases are
in full force and effect and that no Debtor has assigned or pledged,  and hereby
covenants that no Debtor will assign or pledge,  so long as this Agreement shall
remain in effect, the whole or any part of the rights hereby assigned, to anyone
other than the Secured Party.

         (D) Each Debtor does hereby  warrant and represent  that for each Lease
with an original equipment cost in excess of $50,000,  it has taken all possible
action to protect its first-priority  security interest in such leased property,
which  may  include  filing  UCC or  other  financing  statements  (listing  the
applicable  Debtor as the secured party,  the lessee as debtor,  and such leased
property as collateral) in such locations as would be required by applicable law
(if such Debtor were a secured party and the lessee were a debtor) under the UCC
or other  applicable  statute or regulation,  which is assignable to the Secured
Party.  If any Debtor  assumes a pre-existing  Lease,  such Debtor shall use its
best  efforts to comply  with this ss. 3(D) to the extent  permitted  under such
Lease.

         (E)  Subject  to the  provisions  of  this  Agreement,  and  until  the
occurrence of an Event of Default and upon demand by the Secured Party, a Debtor
may  exercise  all the rights and enjoy all the benefits of the lessor under its
Leases.

         4. Books and Records.  Each Debtor shall  faithfully  keep complete and
accurate books and records and make all necessary entries therein to reflect the
quantities,  costs,  current values and locations of all Collateral,  the events
and transactions  giving rise thereto and all payments,  credits and adjustments
applicable  thereto,  shall keep the Secured Party fully and accurately informed
as to the  locations  of all such books and records and shall permit the Secured
Party's  agents to have such access to them and to any other records  pertaining
to the Debtor's business as the Secured Party may request from time to time.

         5.       Control of and Access to Collateral.

          (A)  Prior  to  any  Lease  being   included  in  the  Borrowing  Base
calculation,  each originally executed Lease included in the Collateral shall be
marked  "Original"  and legended in form  satisfactory  to the Secured  Party to
indicate that it is the only original of the Lease held by any Debtor; provided,
however,  that a Debtor may provide its Lessee with a duplicate original,  which
shall be sufficiently  legended so as to indicate that the Debtor holds the true
"Original."  All other copies shall be marked  "copy." The Secured  Party may at
any time and in its  sole  discretion  request  possession  any or all  original
Leases;  from and after such request,  any Leases  subject to such request shall
not be included in the Borrowing Base unless and until such original  Leases are
delivered  by the  Debtors  to the  Secured  Party  together  with a list of the
invoices for the  equipment  being leased  (which list shall include the invoice
number,  invoice date,  vendor  identity,  description  of equipment,  amount of
invoice and the number and date of the check whereby the invoice was paid by the
applicable  Debtor).  Further,  if Secured  Party shall so request in connection
with its periodic  reviews of the  Collateral  and the Borrowing Base (or at any
time

                                       3



after the  occurrence of an Event of Default),  the Debtors shall make available
to Lender the original paid  invoices  with respect to all equipment  related to
Leases, regardless of whether such Leases were made pursuant to Asset Management
Contracts.

         (b) Upon the occurrence of an Event of Default, the Secured Party shall
have the  right at any time to take  possession  of the  Collateral  or any part
thereof.  Notwithstanding  any such taking of possession,  the Collateral  shall
remain at all times at the applicable Debtor's sole risk, and to the full extent
permitted by law the Secured Party shall not be responsible for any loss, damage
or  diminution in the value  thereof.  All costs of  transportation,  packaging,
custody,  processing,  storage,  and insurance of any unit or item of Collateral
which may be  incurred by the  Secured  Party  shall be  promptly  repaid to the
Secured Party by the Debtors  together with interest  thereon at the  Prevailing
Interest  Rate,  and such  Debtor's  liability  to the  Secured  Party  for such
repayment with interest shall be included in the Liabilities.

         (C) If any item or unit of  Collateral  is now or hereafter the subject
of a  certificate  of title or is  required  by law so to be, the  Debtors  will
promptly procure the necessary certificate of title and take all steps necessary
to cause the Secured  Party's lien or security  interest  therein to be noted on
the face of such  certificate and undertake such other steps as may be necessary
to assure  that the  Secured  Party  has a first  priority,  perfected  security
interest in each such item or unit of Collateral,  and shall thereafter  deposit
the original of such certificate of title with the Secured Party.

         (D) The Debtors shall immediately notify the Secured Party of any event
causing any  deterioration,  loss or  depreciation  in value of any  substantial
portion of the  Collateral  and the Debtors' best estimate of the amount of such
deterioration, loss or depreciation.

         (E) The Debtors shall afford the Secured  Party's  agents access to the
Collateral  from  time  to  time  upon  request  for  purposes  of  examination,
inspection  and appraisal  thereof and to verify the Debtors'  books and records
pertaining  thereto.  After an Event of  Default  and upon the  Secured  Party's
demand therefor, the Debtors shall assemble the Collateral and make it available
to the Secured Party at such place reasonably  convenient to both parties as the
Secured Party may designate,  and the Secured  Party's rights to such assemblage
shall be enforceable by injunction.  If an Event of Default shall not exist, the
Secured  Party shall furnish  written prior notice to the Debtors  reasonably in
advance of any intended examination,  inspection, appraisal and verification and
such activity shall commence during the Debtor's normal business hours.

         (F) From and after the occurrence of an Event of Default hereunder, the
Debtors  shall  pay to the  Secured  Party on  demand  any and all  expenses  of
conducting any and all periodic  examinations or reviews or causing any periodic
examinations  or reviews  of  Collateral  determined  to be  appropriate  by the
Secured Party (including but not limited to reasonable attorneys' fees and legal
expenses)  which may be  incurred  by the Secured  Party,  with  interest at the
Prevailing Interest Rate.

         (G) Upon an Event of  Default,  the Secured  Party is hereby  granted a
license or other right to use,  without charge,  Debtors'  labels,  intellectual
property,  or  use  of any  name,  trade  secrets,  tradenames,  trademarks  and
advertising  matter,  or any property of a similar nature, as it pertains to the
Collateral,  in advertising  for sale and selling any  Collateral,  and Debtors'
rights  under all  licenses  and all  franchise  agreements  shall  inure to the
Secured Party's benefit.

                                       4



          6. Maintenance of Collateral;  Sale.  Subject to the Debtors' business
judgment and reasonable commercial practice, the Debtors shall take good care of
the Collateral and shall afford it suitable preventive maintenance.  The Debtors
shall pay the cost of all repairs to or  maintenance of the Collateral and shall
not permit  anything to be done that might in any way impair the value of any of
the Collateral or any of the security intended to be afforded by this Agreement.
The Debtors shall  conscientiously  adhere to a well designed  internal  control
system  with  respect to the  Collateral,  and such  system  shall be capable of
permitting the Debtors and the Secured Party to identify readily at any time the
location and  condition of each and every item of  Collateral.  The Debtors will
not permit any of the  Collateral  to become or be a fixture.  The Debtors shall
not sell,  exchange,  salvage,  replace  or  dispose of any items or unit of its
Inventory or Equipment or any of its rights  therein,  except that so long as no
Debtor is in default  hereunder,  the  Debtors  shall have the right to sell its
Inventory and Equipment in each case in the ordinary  course of its business and
it shall have the right to lease or re-lease its  Inventory and Equipment in the
ordinary course of its business.

         7.       Insurance.

         (a) The Debtors  shall bear the risk of each item or unit of  Inventory
and Equipment being lost, destroyed, irreparably damaged or rendered permanently
unfit for sale, lease or use or being damaged in part, from any cause whatsoever
at any time  during  the term of this  Agreement,  and shall at its own cost and
expense  obtain and keep in full force and effect,  in kind and form  reasonably
satisfactory to the Secured Party, or in the alternative  shall cause the lessee
under  each  applicable  Lease to do the  same  with  respect  to  Inventory  or
Equipment  subject to the lessee's  Lease,  all risk of physical  loss or damage
insurance covering the Inventory and Equipment wherever the same may be located,
insuring against the risks of fire, explosion, theft and such other risks as are
customarily  insured against by  organizations  engaged in the same business and
similarly  situated  with the Debtors  (and  specifically  including  vandalism,
malicious mischief coverage,  loss overboard and breakage), in an amount usually
carried by organizations engaged in the same business or similarly situated with
the Debtors.  All policies of such insurance shall be written for the benefit of
the applicable Debtor as the insured.

         (b) If the Debtors or the applicable lessee fails to pay any premium on
any such insurance,  the Secured Party shall have the right,  but shall be under
no obligation,  to pay such premium for such Debtor's account. Such Debtor shall
repay to the Secured Party on demand all sums which the Secured Party shall have
paid under this section in respect of insurance premiums,  with interest thereon
at the  Prevailing  Interest  Rate,  and such Debtor's  liability to the Secured
Party for such  repayment  with interest  shall be included in the  Liabilities.
Each Debtor hereby  assigns to the Secured Party any return or unearned  premium
which may be due upon the cancellation  for any reason  whatsoever of any policy
of insurance  maintained  in respect of the  Collateral  and hereby  directs the
insurer  to pay the  Secured  Party any  amount so due.  The  Debtors'  right to
receive  payment of any such return or unearned  premium and the proceeds of any
such  insurance  shall  constitute  a part of the  Collateral  for all  purposes
hereof.

         8.       Title to Collateral.

          (A) Each Debtor has acquired or shall  acquire  absolute and exclusive
title to each and every item or unit of the Collateral  attribute to it free and
clear of all liens, claims, security interests and other encumbrances, except as
permitted under the Credit  Agreement,  and each Debtor shall warrant and defend
its  title to such  Collateral,  subject  to the  rights of the  Secured  Party,
against the claims and demands of all persons  whomsoever.  Without limiting the
generality  of the  foregoing,  no Debtor  shall  pledge,  assign  or

                                       5


otherwise encumber,  or permit any liens or security interests (other than those
in favor of the Secured Party) to attach to, any of the  Collateral,  nor permit
any of the Collateral to be levied upon under any legal process.

         (b) The Secured Party may, at its sole election but without  obligation
to do so, discharge any unpermitted encumbrance pertaining to the Collateral and
all expenses  incurred by the Secured Party in so doing,  together with interest
thereon at the Prevailing  Interest Rate,  shall be added to the Liabilities and
shall be payable by the Debtors on demand.

     9. Taxes and Liens.  The Debtors shall promptly notify the Secured Party in
the event there ever arises against any of the  Collateral any lien,  assessment
or tax or other liability,  whether or not entitled to priority over the Secured
Party's  security  interest  hereunder.  In any such event,  whether or not such
notice is given,  the Secured Party shall have the right (b)ut shall be under no
obligation)  to pay any tax or other  liability  of the  Debtors  deemed  by the
Secured Party in good faith to affect the Secured Party's  interests  hereunder.
The  Debtors  shall  repay to the  Secured  Party on demand  all sums  which the
Secured  Party  shall have paid under this  section in respect of taxes or other
liabilities of the Debtors,  with interest  thereon at the  Prevailing  Interest
Rate,  and the Debtors'  liability to the Secured Party for such  repayment with
interest  shall be  included  in the  Liabilities.  The  Secured  Party shall be
subrogated  to the extent of any such  payment by it to all the rights and liens
of the payee against the Debtors' assets.

         10.      Collection of Accounts, Etc.

         (A) Until  otherwise  notified  by the Secured  Party,  the Debtors may
collect all the  Accounts  but the  Proceeds of all Accounts so collected by the
Debtors shall be held by the Debtors in trust for the Secured Party. The Secured
Party may at any time during the existence of an Event of Default  terminate the
authority  hereby given to the Debtors to collect the Proceeds of such  Accounts
and,  acting if it so chooses  in each  Debtor's  name,  collect  such  Accounts
itself,  directly or through an agent,  sell, assign,  compromise,  discharge or
extend the time for payment of such  Accounts,  institute  legal  action for the
collection of such  Accounts and do all acts and things  necessary or incidental
thereto,  and each  Debtor  hereby  ratifies  all that the  Secured  Party shall
lawfully do under the authority  hereby  granted to it. The Secured Party may at
any time  during the  existence  of an Event of Default,  without  notice to any
Debtor, notify any account debtor on any such Account that such Account has been
assigned to the Secured Party and is to be paid  directly to the Secured  Party.
Alternatively,  at its election the Secured Party may require any Debtor to, and
in such event such Debtor at its sole expense will,  notify its account  debtors
that payments  thereon are thenceforth to be made directly to the Secured Party.
Without the written  consent of the Secured  Party in each case, no Debtor shall
compromise,  discharge,  extend the time for payment of or  otherwise  grant any
indulgence  or  allowance  with  respect  to any such  Account  except for minor
indulgences  or  allowances  in the  ordinary  course of business  which are not
related to an extension  or  restructuring  of credit to an account  debtor of a
duration in excess of 30 days in any instance.

         (B) If any such Account arises out of a contract with the United States
or  any  department,   agency  or  instrumentality  thereof,  the  Debtors  will
immediately  so  notify  the  Secured  Party in  writing  and will  execute  all
instruments  and take all steps  required by the Secured Party in order that the
security interest of the Secured Party hereunder in all such Accounts under such
contract  and  the  Proceeds  thereof  shall  be  perfected  under  the  Federal
Assignment of Claims Act.

                                       6


          (C) From and after the  occurrence  and during the  continuance of any
Event  of  Default,  if any of  the  Collateral  is or  becomes  evidenced  by a
promissory note, draft, trade acceptance,  Chattel Paper, Instrument or Document
of Title,  the Debtors  will  promptly  deliver  the same to the  Secured  Party
appropriately  endorsed to the Secured Party's order.  Regardless of the form of
such  endorsement,  each Debtor hereby  waives  presentment,  demand,  notice of
dishonor,  protest  and notice of protest  and all other  notices  with  respect
thereto.  The Debtors  will  promptly  notify the Secured  Party of any Material
Adverse  Change of which it has  knowledge  in the  financial  condition  of any
account  debtor  on  any  material  Account  pertaining  to a  Lease  or in  the
collectibility of any of such Accounts, and of all claims,  rejections,  returns
and adjustments which may result in a material  reduction of the liability of an
account debtor on any such Account.

         11.      Locations of the Collateral; Name.

         (A) If any of the Collateral or any of the Debtors' records  concerning
any of the  Collateral  are at any time to be located on premises  leased by any
Debtor, or any premises owned by any Debtor subject to a mortgage or other lien,
the Debtors shall obtain and deliver to the Secured Party, prior to the delivery
of any such  Collateral  or books or records to such  premises,  an agreement in
form  satisfactory to the Secured Party waiving the  landlord's,  mortgagee's or
other  lienholder's  right to enforce  against the  Collateral  or the  Debtors'
records  concerning  the same and  assuring the Secured  Party's  access to such
Collateral and books and records to facilitate the Secured  Party's  exercise of
its rights to take  possession  thereof.  The  location of each  Debtor's  chief
executive  office and all  locations  at which any Debtor  maintains  a place of
business  are set forth in  Schedule  A, and each  Debtor  agrees to provide the

business  or the  establishment  of any  additional  place  of  business  of the
Debtors.

         (B) Each Debtor represents and warrants that at no time during the past
five (5) years has it been known by or used any other name,  including any trade
or fictitious name, except as disclosed in Schedule A.

         12.  Further  Assurances.  The Debtors shall  continue to conduct their
business  in  substantially  the manner  heretofore  conducted  and will make no
material  changes  therein which might impair the security of the Secured Party.
The Debtors shall execute and deliver to the Secured Party from time to time all
such  other  agreements,  instruments  and other  documents  (including  without
limitation all requested financing and continuation  statements) and do all such
other and further acts and things as the Secured Party may reasonably request in
order  further  to  evidence  or carry out the  intent of this  Agreement  or to

or sales.  Each Debtor  further  agrees  that ten (10) days shall be  reasonable
prior notice of the date of any public sale or other  disposition  of all or any
part of the  Collateral,  or of the date on or after which any  private  sale or
other disposition of the same may be made.

     (C) The exercise by the Secured  Party of any one right or remedy shall not
be deemed a waiver or  release of or any  election  against  any other  right or
remedy, and the Secured Party may proceed against the Debtors or any of them and
the  Collateral  and any other  collateral  granted by any Debtor to the Secured
Party under any other  agreement,  all in any order and  through  any  available
remedies. A waiver on any one occasion shall not be construed as a waiver or bar
on any future occasion. All property of any kind held at any time by the Secured
Party as Collateral shall stand as one general  continuing  collateral  security
for all the  Liabilities  and may be retained  by the Secured  Party as security
until all the  Liabilities  are fully  satisfied.  The Debtors  shall pay to the
Secured Party on demand any and all expenses  (including  reasonably  attorneys'
fees and legal  expenses) which may have been incurred by the Secured Party with
interest at the  Prevailing  Interest Rate (i) in the  prosecution or defense of
any  action  growing  out of or  connected  with  the  subject  matter  of  this
Agreement, the Liabilities,  the Collateral or any of the Secured Party's rights
therein or thereto; or (ii) in connection with the custody,  preservation,  use,
operation,  preparation for sale or sale of any of the Collateral, the incurring
of all of which are hereby  authorized to the extent the Secured Party deems the
same advisable. The Debtors' liability to the Secured Party for any such payment
with  interest  shall  be  included  in the  Liabilities.  The  Proceeds  of any
Collateral  received by the Secured  Party at any time before or after  default,
whether from a sale or other  disposition  of Collateral  or  otherwise,  or the
Collateral  itself,  may be applied to the payment in full or in part of such of
the  Liabilities  and in such order and manner as the  Secured  Party may elect.
Each Debtor to the extent of its rights in the  Collateral  waives and  releases
any right to require the Secured  Party to collect any of the  Liabilities  from
any other of the  Collateral  or any other  collateral  then held by the Secured
Party under any theory of marshaling of assets or otherwise.

          14. Power of Attorney.  Each Debtor  hereby  irrevocably  appoints any
officer,  employee  or  agent  of the  Secured  Party  as its  true  and  lawful
attorney-in-fact  with power to (i) endorse such  Debtor's  name upon any notes,
checks,  drafts,  money  orders,  or  other  instruments  or  payments  or other
Collateral  that may come into the  Secured  Party's  possession;  (ii) sign and
endorse such  Debtor's name upon any  documents of title,  invoices,  freight or
express bills, assignments,  verifications and notices in connection with any of
the  Collateral,  and any instruments or documents  relating  thereto or to such
Debtor's rights therein; and (iii) execute in such Debtor's name and file one or
more financing,  amendment and continuation  statements covering the Collateral.
Any such  attorney of such Debtor shall have full power to do any and all things
necessary  to be done  with  respect  to the  above  transactions  as fully  and
effectually  as such Debtor might do, and each Debtor  hereby  ratifies all that
said attorney shall lawfully do or cause to be done by virtue hereof.

         15.  Financing  Statements.  Each Debtor  shall  execute all  financing
statements and amendments  thereto as the Secured Party may request from time to
time to evidence the security  interest  granted to the Secured Party  hereunder
and will pay all filing fees and taxes,  if any,  necessary to effect the filing
thereof.  Wherever permitted by law, each Debtor authorizes the Secured Party to
file financing  statements with respect to the Collateral  without the signature
of such Debtor.  A copy of this  Agreement or a copy of any financing  statement
prepared in  connection  with this  Agreement may itself be filed as a financing
statement.

         16.      Miscellaneous.

         (A) This Agreement shall commence on the date hereof and shall continue
in full force and effect so long as any of the Liabilities shall exist from time
to time.

         (b)  No  modification  or  waiver  of any  provision  hereof  shall  be
effective unless the same is in writing and signed by the party against whom its
enforcement is sought.  This Agreement and any amendment hereto or waiver of any
provision  hereof  may be signed in any  number  of  counterparts  with the same
effect as if the signatures thereto and hereto were upon the same instrument.

         (C) The representations, warranties, covenants and agreements contained
herein are all material and continuing,  and any breach of them shall constitute
a material breach of this Agreement.

         (D) All the rights and remedies of the Secured Party hereunder shall be
concurrent and cumulative  with and not alternative to or in lieu of the Secured
Party's rights and remedies under any other agreement or agreements.

         (E) This  Agreement  shall bind and inure to the benefit of the parties
and their respective successors and assigns,  except that no Debtor shall assign
any of its rights hereunder without the Secured Party's prior written consent.

         (F)  Any   provision  of  this   Agreement   which  is   prohibited  or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability  without  invalidating the
remaining  provisions hereof or affecting the validity or enforceability of such
provision in any other jurisdiction.

                                       9


          (G) No persons other than the Debtors and the Secured  Party,  and the
assignees of the Secured  Party,  are intended to be benefitted  hereby or shall
have any rights hereunder, as third-party beneficiaries or otherwise.

         (H) Each Debtor acknowledges that this Agreement and the obligations of
the Debtors  hereunder and the security created or intended to be created hereby
have  constituted,  and were intended by such Debtor to  constitute,  a material
inducement  to the Secured  Party to enter into the Credit  Agreement  and other
agreements  referred to therein,  knowing that the Secured  Party will rely upon
this Agreement. Each Debtor intends to be legally bound hereby.

         (I) This  Agreement  shall be deemed to be a  contract  made  under and
shall  be  construed  in  accordance  with  the  laws  of  the  Commonwealth  of
Pennsylvania without regard to Pennsylvania or federal principles of conflict of
laws.

                                       10




          IN WITNESS WHEREOF, the parties hereto have each caused this Agreement
