         2. ASSIGNMENT AND GRANT OF SECURITY INTEREST.

                  .1 Security Interest in Personal Property. As security for the
due and punctual payment and performance of the Secured Indebtedness in full,
each Borrower hereby agrees that the Agent shall have, and each Borrower hereby
grants to and creates in favor of the Agent, for the benefit of each of the
Agent and the Banks, (i) to secure all of the Secured Indebtedness (other than
the Guaranty Related Obligations), a continuing first priority security interest
in and to each Borrower's respective Collateral subject only to Permitted Liens
and (ii) to secure all of the Guaranty Related Obligations, a continuing second
priority security interest in and to each Borrower's respective Collateral
subject only to Permitted Liens. Without limiting the generality of Section 5
below, each Borrower further agrees that with respect to each item of Collateral
as to which (i) the creation of valid and enforceable security interests is not
governed exclusively by the Code or (ii) the perfection of valid and enforceable
security interests therein under the Code cannot be accomplished either by the
Agent taking possession thereof or by the filing in appropriate locations of
appropriate Code financing statements executed by the Borrower, such Borrower
will at its expense execute and deliver to the Agent such documents, agreements,
notices, assignments and instruments and take such further actions as may be
reasonably requested by the Agent from time to time for the purpose of creating
a valid and perfected first priority Lien on such item, subject only to
Permitted Liens, enforceable against the Borrower and all third parties to
secure the Secured Indebtedness.

                  .2 Special Collateral. Immediately upon any Borrower's receipt
of that portion of the Collateral which is or becomes evidenced by an agreement,
instrument and/or document, including, without limitation, promissory notes,
trade acceptances, documents of title and warehouse receipts (the "Special
Collateral"), such Borrower shall deliver the original thereof to the Agent for
the benefit of the Banks, together with appropriate endorsements or other
specified evidence (in form and substance acceptable to the Agent) of assignment
thereof to the Agent for the benefit of the Banks. Each Borrower acknowledges
that it is the intent of the Borrowers, the Agent and the Banks that all
Inventory now owned or hereafter acquired by the Borrowers shall be Collateral
to secure the Secured Indebtedness. To the extent that Article 9 of the Code
does not govern the creation and/or perfection of the Bank's Prior Security
Interest intended to be created hereunder, each Borrower agrees to execute and
deliver such further documents and instruments as the Agent may from time to
time request in order to adequately create and fully perfect a first priority
Lien with respect to such property.

                                      -4-

         3. ACCOUNTS AND INVENTORY.

                  .1 Verification of Accounts; Inspection; Audit. At any
reasonable time or times hereafter, each Borrower shall fully and promptly
cooperate with the Agent (and its officers, employees and agents) in verifying
the validity, amount or any other matter relating to any Accounts. At any
reasonable time or times hereafter, any of the Agent's officers, employees or
agents shall have the right, in the Banks' name or in the name of the Borrowers,
to verify the validity, amount or any other matter relating to any Accounts by
mail, telephone or otherwise; provided, however, unless an Event of Default or
Potential Default has occurred, without the prior written consent of any
Borrower, none of the Agent's officers, employees or agents will directly
contact any Account Debtor to verify such matters. The Agent (by any of its
officers, employees or agents) shall have the right, at any time and from time
to time during a Borrower's usual business hours, to audit and inspect the
Collateral and all records related thereto (and to make extracts from such
records), and shall have access to the premises upon which any of the Collateral
is located, and the right to discuss the Collateral, at any time, with any
attorney, accountant, or creditor of such Borrower and, after the occurrence of
an Event of Default or Potential Default, with any Account Debtor. Subject to
the limitation set forth in Section 9.5 of the Credit Agreement, all reasonable
expenses and costs incurred by the Agent in connection with any audit or
inspection of the Collateral shall be reimbursed by such Borrower on demand.

                  .2 Physical Inventory. A physical inventory shall be conducted
no less frequently than monthly. A Schedule of Inventory based on such physical
inventory shall be provided to the Agent for the benefit of the Banks as soon as
available and in any event within ten (10) Business Days after the end of each
calendar month, together with such supporting information, including, without
limitation, invoices relating to such Borrower's purchase of goods listed in
said Schedule, as the Agent may reasonably request.

                  .3 Notices Regarding Disputed Account. In the event any
amounts due and owing in excess of $100,000 are at any time in dispute between
any Account Debtor and a Borrower, such Borrower shall provide the Agent with
written notice thereof at the time of submission of the next Schedule of
Accounts pursuant to Section 4.2 hereof, explaining in detail the reason for the
dispute, all claims related thereto and the amount in controversy. Each Borrower
will in any event notify the Agent if such Borrower receives notice that an
Account Debtor intends to revoke acceptance of any goods having an aggregate
value in excess of $50,000, such notice to be given to the Agent within three
(3) Business Days after such Borrower receives notice of such intention to
revoke.

                  .4 Returns of Inventory. Each Borrower shall notify 

                                      -5-
   6
the Agent of any returns of Inventory, the sale of which generated Accounts on
which the Account Debtor is then (prior to such return) obligated to pay an
amount in excess of $100,000 in the aggregate on any single day.

                  .5 Collection of Accounts; Management of Collateral.

                           (a) The Borrower's Collection. Until a Borrower's
authority to do so is terminated (which the Agent may do at any time after the
occurrence of an Event of Default), such Borrower will, at its own cost and
expense but on the Agent's behalf and for the Agent's accounts, collect and
otherwise enforce as the Agent's property and in trust for the Agent for the
benefit of the Banks, in accordance with such Borrower's normal collection
practices, all amounts unpaid on Accounts.

                           (b) Bank's Collection. After termination of any
Borrower's authority to collect the Accounts, as provided in subparagraph (a)
above, the Agent shall have the rights set forth in this subparagraph (b). The
Agent shall have the right to send notice of assignment and/or notice of the
Bank's security interest to any and all Account Debtors or any third party
holding or otherwise concerned with any of the Collateral, and thereafter the
Agent, for the benefit of the Banks, shall have the sole right to collect the
Accounts and/or take possession of the Collateral and the books and records
relating thereto. The Agent, for the benefit of the Banks, shall have the right
to receive, endorse, assign and/or deliver in its name or the name of such
Borrower any and all checks, drafts and other instruments for the payment of
money relating to the Accounts, and each Borrower hereby waives notice of
presentment, protest and non-payment of any instrument so endorsed. Without
limiting Section 12 hereof, each Borrower hereby constitutes the Agent or its
designee as such Borrower's attorney-in-fact with power to endorse such
Borrower's name upon any notes, acceptances, checks, drafts, money orders or
other evidences of payment or Collateral that may come into the Agent's or a
Bank's possession, to sign such Borrower's name on any invoice or bill of lading
relating to any of the Accounts, drafts against Account Debtors, assignments and
verifications of Accounts and notices to Account Debtors, to notify the Post
Office authorities to change the address for delivery of mail addressed to such
Borrower to such address as the Agent may designate, and to do all other acts
and things necessary to carry out this Agreement. The Agent for the benefit of
the Banks may, without notice to or consent from any Borrower, sue upon or
otherwise collect, extend the time of payment of, or compromise or settle for
cash, credit or otherwise upon any terms, any of the Accounts or any securities,
instruments or insurance applicable thereto and release the obligor thereon. The
Agent is authorized and empowered to accept the return of the goods represented
by any of the Accounts, without notice to or consent by any Borrower, all
without discharging or in any way affecting any Borrower's liability hereunder.
Any notice sent to Account Debtors by the Agent may, at the Agent's sole
discretion, 

                                      -6-
   7
be sent on the relevant Borrower's stationery, in which event such Borrower
shall co-sign such notice with the Agent. To the extent that any Law or custom
or any contract or agreement with any Account Debtor requires notice to or the
approval of the Account Debtor in order to perfect such assignment of and
security interest in Accounts, each Borrower agrees to promptly give such notice
or obtain such approval.

                           (c) Relationship of the Borrower and Bank. Nothing
herein contained shall be construed to constitute a Borrower as agent of the
Agent for any purpose whatsoever, and the Agent shall not be responsible or
liable for any shortage, discrepancy, damage, loss or destruction of any part of
the Collateral wherever the same may be located and regardless of the cause
thereof, except to the extent the same results from the Agent's own gross
negligence or willful misconduct. The Agent shall not, under any circumstances
or in any event whatsoever, have any liability for any error or omission or
delay of any kind occurring in the settlement, collection or payment of any of
the Accounts or any instrument received in payment thereof or for any damage
resulting therefrom. The Agent does not, by anything herein or in any assignment
or otherwise, assume any of the Borrowers' obligations under any contract or
agreement assigned to the Agent, and the Agent shall not be responsible in any
way for the performance by the Borrowers of any of the terms and conditions
thereof.

         4. REPRESENTATIONS AND WARRANTIES.

                  .1 General Representations and Warranties. Each Borrower
represents and warrants to the Agent that such Borrower has and will continue to
have good and marketable title to its respective Collateral which such Borrower
purports to own or which is reflected as owned in its books and records free and
clear of all Liens and other encumbrances except Permitted Liens. The locations
of each Borrower's chief executive office, the Collateral and the records
pertaining thereto are specified on Schedule A hereto, which is incorporated
herein by reference. Except as set forth on Schedule A, none of the Collateral
is located on premises not owned or leased by a Borrower or is on consignment.

                  .2 Account Representations and Warranties. With respect to its
Accounts, each Borrower represents and warrants to the Agent that:

                           (a) the Agent may rely, in determining which Accounts
listed on any Schedule of Accounts are Qualified Accounts, on all statements and
representations made by such Borrower on or with respect to any such Schedule of
Accounts; and

                           (b) unless otherwise indicated in writing by such
Borrower, such Borrower has determined that all of the Accounts listed in each
Schedule of Accounts will qualify as Qualified

                                      -7-
   8
Accounts.

                  .3 Inventory Representations and Warranties. With respect to
Inventory, each Borrower represents and warrants to the Agent that:

                           (a) the Agent may rely, in determining which items of
Inventory listed on any Schedule of Inventory are Qualified Inventory, on all
statements and representations made by such Borrower on or with respect to any
such Schedule of Inventory; and

                           (b) unless otherwise indicated in writing by such
Borrower, such Borrower has determined that all of the Inventory listed in each
Schedule of Inventory will qualify as Qualified Inventory.

         5. FURTHER ASSURANCES. Each Borrower will, from time to time, at its
expense, faithfully preserve and protect the Agent's security interest in the
Collateral as a continuing first and second priority perfected security interest
under the Code, subject only to Permitted Liens, and will do all such other acts
and things and will, upon request therefor by the Agent, execute, deliver, file
and record all such other documents and instruments, including, without
limitation, financing statements, security agreements, pledges, assignments,
documents and powers of attorney with respect to the Collateral, and pay all
filing fees and taxes related thereto as the Agent in its reasonable discretion
may deem necessary or advisable from time to time in order to preserve, perfect
or protect any security interest granted or purported to be granted hereby or to
enable the Agent to exercise and enforce its rights and remedies hereunder with
respect to any of the Collateral. Each Borrower agrees that a carbon,
photographic or other reproduction of this Security Agreement or of a financing
statement is sufficient as a financing statement; provided, however, each
Borrower makes no representation that any filing office or officer will accept
for filing any such financing statement.

         6. COVENANTS. Each Borrower covenants and agrees that (a) it will
maintain in good condition and repair and shall protect and preserve the
Collateral and such Collateral will be insured in accordance with Section 7.1.3
of the Credit Agreement; (b) it will not sell, assign or otherwise dispose of
any portion of the Collateral except sales or dispositions as permitted in
Section 7.2.7 of the Credit Agreement; (c) it (i) will obtain and maintain sole
and exclusive possession of the Collateral, (ii) will maintain and keep its
chief executive office, the location of the Collateral and the location of the
records pertaining thereto, at the location(s) specified on Schedule A hereto or
at such other location as it may designate from time to time by prior written
notice to the Agent, and (iii) will keep materially accurate and complete books
and records concerning the Collateral and such other books and records as may be
required 

                                      -8-
   9
under the Credit Agreement; (d) it will promptly furnish to the Agent such
information and documents relating to the Collateral as the Agent may reasonably
request in order to confirm the status of the Agent's security interest in such
Collateral; (e) it will not take or omit to take any actions, the taking or the
omission of which might result in a material adverse alteration or impairment of
the Collateral or in a violation of this Security Agreement or the Credit
Agreement; (f) it will not, without the prior written consent of the Agent,
which will not be unreasonably withheld or delayed, waive or release any
obligation of any party to any part of the Collateral, except in the ordinary
course of a Borrower's business or in connection with the disposition of assets
permitted under the Credit Agreement; and (g) it will execute and deliver to the
Agent and record such supplements to this Security Agreement and additional
assignments as the Agent reasonably may request to evidence and confirm the
security interest herein contained.

         7. PAYMENT OF INSURANCE PREMIUMS. In the event a Borrower, at any time
hereafter, shall fail to obtain or maintain any of the policies of insurance in
accordance and compliance with Section 7.1.3 of the Credit Agreement or to pay
any premium in whole or in part relating thereto, then the Agent, without
waiving or releasing any obligations of or any Event of Default by such Borrower
under the Credit Agreement, may at any time thereafter (but shall be under no
obligation to) obtain and maintain such policies of insurance and pay such
premium and take any other action with respect thereto which the Agent deems
advisable. All sums so disbursed by the Agent, including reasonable attorneys'
fees, court costs, expenses and other charges relating thereto, shall be due and
payable by such Borrower upon demand by the Agent, shall be additional Secured
Indebtedness, and shall bear interest from the date due until paid by such
Borrower at the Base Rate as set forth in the Credit Agreement and any increase
in the Base Rate in accordance with the Credit Agreement.

         8. PRESERVATION OF SECURITY INTERESTS. Each Borrower assumes full
responsibility for taking and hereby agrees to take any and all necessary steps
to preserve and defend the Agent's right, title and security interest in and to
such Borrower's Collateral against the claims and demands of all persons. The
Agent shall be deemed to have exercised reasonable care in the custody and
preservation of a Borrower's Collateral in the Agent's possession if the Agent
takes such action for that purpose as such Borrower shall request in writing,
provided that such requested action will not, in the judgment of the Agent,
impair the security interest in such Borrower's Collateral created hereby or the
Agent's rights in, or the value of, such Collateral, and provided further that
such written request is received by the Agent in sufficient time to permit the
Agent to take the requested action.

         9. AGENT'S RIGHTS WITH RESPECT TO THE COLLATERAL. At any 

                                      -9-
   10
time and from time to time, whether or not an Event of Default shall have
occurred, and without notice to or consent of the Borrowers, the Agent may, at
its option, do any or all of the following: (a) do anything which a Borrower is
required but fails to do hereunder, and in particular, without limiting the
generality of the foregoing, the Agent may, if a Borrower fails to do so,
provided that the Agent shall take such action within the applicable time period
or cure period provided for in the Credit Agreement, (this proviso to apply only
to the extent so covered in the Credit Agreement) (i) insure or take any
reasonable steps to protect the Collateral, (ii) pay any or all taxes, levies,
expenses and costs arising with respect to the Collateral, or (iii) pay any or
all premiums payable on any policy of insurance required to be obtained or
maintained hereunder in accordance with Section 7 hereof; (b) inspect the
Collateral of any Borrower at any reasonable time; and (c) pay any amounts the
Agent reasonably elects to pay or advance hereunder on account of taxes or other
costs, fees or charges arising in connection with the Collateral of any Borrower
either directly to the payee(s) of such cost, fee or charge, directly to such
Borrower, or to such payee(s) and such Borrower jointly. All sums so disbursed
by the Agent under this Section or any other Section of this Security Agreement,
including reasonable attorneys' fees, court costs, expenses and other charges
relating thereto, shall be due and payable by the Borrowers upon demand by the
Agent, shall be additional Secured Indebtedness, and shall bear interest at the
Base Rate and any increase in the Base Rate in accordance the Credit Agreement.

         10. REMEDIES ON DEFAULT. If there shall have occurred an Event of
Default under the terms of the Credit Agreement, then the Agent shall have such
rights and remedies with respect to the Collateral or any part thereof and the
proceeds thereof as are provided by the Code and such other rights and remedies
with respect thereto which it may have at law or in equity or under the Credit
Agreement or this Security Agreement. In addition, upon the occurrence of an
Event of Default, the Borrowers, at the request of the Agent, shall assemble all
or any portion of the Collateral at such locations as the Agent shall designate
which are reasonably convenient to the Borrowers, and the Agent may sell,
assign, give an option or options to purchase or otherwise dispose of all or any
part of the Collateral at any public or private sale at such place or places and
at such time or times and upon such terms, whether for cash or on credit, and in
such manner, as the Agent may determine, and apply the proceeds so received in
accordance with Section 11 hereof. Written notice of sale mailed by certified
mail, return receipt requested, to the Borrowers at least ten (10) days prior to
such sale shall be deemed reasonable notice.

                  10. In the event of a breach by a Borrower in the performance
of any of the terms of this Security Agreement, the Agent may demand specific
performance of this Security Agreement and seek injunctive relief and may
exercise any other remedy, 

                                      -10-
   11
available at law or in equity, it being recognized that the remedies of the
Agent at law may not fully compensate the Agent for the damages they may suffer
in the event of a breach hereof.

         11. APPLICATION OF PROCEEDS. The security interest in the Collateral
granted to and created in favor of the Agent by this Security Agreement shall be
for the sole benefit of the Agent for the benefit of the Banks. Each of the
rights, privileges and remedies provided to the Agent hereunder or otherwise by
Law with respect to the Collateral shall be exercised by the Agent and any
Collateral or proceeds thereof held or realized upon at any time by the Agent
shall inure to the benefit of the Agent and shall be applied in accordance with
the provisions of Section 8.2.5 of the Credit Agreement. Each Borrower shall be
liable for any deficiency if the proceeds of any sale, assignment, giving of an
option or options to purchase or other disposition of the Collateral is
insufficient to pay all amounts to which the Agent is entitled.

         12. ATTORNEYS-IN-FACT. Each Borrower hereby irrevocably appoints the
Agent, its officers, employees and agents, or any of them, as attorneys-in-fact,
with full power of substitution, for such Borrower for the purpose of carrying
out the provisions of this Security Agreement and taking any action and
executing, delivering, filing and recording any instruments which the Agent may
deem necessary or advisable to accomplish the purposes hereof, which power of
attorney being given for security is coupled with an interest and irrevocable.
Such attorneys-in-fact shall not be liable for any acts of omission or
commission, nor for any error of judgment or mistake of fact or Law, except to
the extent the same results from the gross negligence or willful misconduct of
the Agent, its officers, employees or agents. Each Borrower hereby ratifies and
confirms and agrees to ratify and confirm all action taken by the Agent, its
officers, employees or agents pursuant to the foregoing power of attorney.

         13. INDEMNITY AND EXPENSES

                           (a) In accordance with the Credit Agreement, the
Borrowers unconditionally and jointly and severally agree to indemnify the Agent
from and against any and all claims, losses and liabilities arising out of or
resulting from this Security Agreement (including enforcement of this Security
Agreement), except claims, losses or liabilities resulting from the gross
negligence or willful misconduct of the Agent on behalf of the Banks.

                           (b) The Borrowers unconditionally and jointly and
severally agree upon demand to pay to the Agent the amount of any and all
reasonable and necessary out-of-pocket costs, expenses and disbursements for
which reimbursement is customarily obtained, including fees and expenses of its
counsel, which the Agent may incur in connection with (i) the administration of
this Security Agreement, (ii) the custody, preservation, use or 

                                      -11-
   12
operation of, or the sale of, collection from, or other realization upon, any of
the Collateral, (iii) the exercise or enforcement of any of the rights of the
Agent hereunder or (iv) the failure by the Borrowers to perform or observe any
of the provisions hereof.

         14. TERMINATION. Upon payment in full of the Secured Indebtedness and
termination of the Credit Agreement and the Revolving Credit Commitment, this
Security Agreement shall terminate and be of no further force and effect, and
the Agent shall thereupon promptly return to each Borrower such of its
Collateral and such other documents delivered by such Borrower hereunder as may
then be in the Agent's possession. Upon any such termination, the Agent will, at
the Borrower's expense, execute and deliver to each Borrower such documents as
such Borrower shall reasonably request to evidence such termination. The Agent,
upon request of a Borrower, shall return and release the Agent's security
interest in any of its Collateral which is sold prior to the occurrence of an
Event of Default (but not the proceeds thereof), provided such sale is permitted
by, and made in accordance with, the provisions of the Credit Agreement.

         15. MODIFICATIONS, AMENDMENTS AND WAIVERS. Any and all agreements
amending or changing any provision of this Security Agreement or the rights of
the Agent hereunder, and any and all waivers or consents to Events of Default or
other departures from the due performance of the Borrowers hereunder, shall be
made only pursuant to the provisions of Section 10.1 of the Credit Agreement.

         16. NO IMPLIED WAIVERS; CUMULATIVE REMEDIES; WRITING REQUIRED. No
course of dealing and no failure or delay on the part of the Agent in exercising
any right, remedy, power or privilege hereunder shall affect any other or future
exercise thereof or operate as a waiver thereof; nor shall any single or partial
exercise thereof or any abandonment or discontinuance of steps to enforce such a
right, power, remedy or privilege preclude any further exercise thereof or of
any other right, power, remedy or privilege. The rights and remedies of the
Agent under this Security Agreement are cumulative and not exclusive of any
rights or remedies which they would otherwise have. Any waiver, permit, consent
or approval of any kind or character on the part of the Agent of any breach or
default under this Security Agreement or any such waiver of any provision or
condition of this Security Agreement must be in writing and shall be effective
only to the extent specifically set forth in such writing.

         17. NOTICES. All notices, statements, requests, demands and other
communications given to or made upon the Borrowers or the Agent in accordance
with the provisions of this Security Agreement shall be given or made as
provided in Section 10.6 of the Credit Agreement.

                                      -12-
   13
         18. SEVERABILITY. The provisions of this Security Agreement are
intended to be severable. If any provision of this Security Agreement shall be
held invalid or unenforceable in whole or in part in any jurisdiction, such
provision shall, as to such jurisdiction, be ineffective to the extent of such
invalidity or unenforceability without in any manner affecting the validity or
enforceability thereof in any other jurisdiction or the remaining provisions
hereof in any jurisdiction.

         19. GOVERNING LAW. This Security Agreement shall be deemed to be a
contract under the Laws of the Commonwealth of Pennsylvania and for all purposes
shall be governed by and construed in accordance with the internal Laws of said
Commonwealth without reference to its conflicts of law principles, except as
required by mandatory provisions of Law and except to the extent that the
validity or perfection of security interests hereunder, or remedies hereunder
with respect to any particular Collateral, is governed by the laws of a
jurisdiction other than the Commonwealth of Pennsylvania.

         20. DURATION; SURVIVAL. All representations, warranties and covenants
of the Borrowers contained herein or made in connection herewith shall survive
the making of the Loans and shall not be waived by the execution and delivery of
this Security Agreement, any investigation by the Agent, the making of any of
the Loans, or the payment in full of the Loans and termination of the Revolving
Credit Commitment.

         21. PRIOR UNDERSTANDING. This Security Agreement supersedes all prior
understandings and agreements, whether written or oral, between the parties
hereto and thereto relating to the transactions provided for herein and therein.

         22. SUCCESSORS AND ASSIGNS. This Security Agreement shall be freely
assignable and transferable by the Agent in connection with the assignment or
transfer of the Secured Indebtedness which assignment is addressed in and
governed by the Credit Agreement; however, the duties and obligations of the
Borrowers may not be delegated or transferred by the Borrowers without the prior
written consent of the Agent. The rights and privileges of the Agent shall inure
to the benefit of its successors and assigns, and the duties and obligations of
the Borrowers shall bind the Borrowers and their respective successors and
assigns. Except to the extent otherwise required by the context of this Security
Agreement, the word "Banks" where used in this Security Agreement shall mean and
include any holder of a Note, or assignee of an interest therein, originally
issued to a Bank under the Credit Agreement, and each such holder of a Note, or
assignee of an interest therein, shall be bound by and have the benefits of this
Security Agreement to the same extent as if such holder had been a signatory
hereto.

         23. COUNTERPARTS. This Security Agreement may be executed in any number
of counterparts and by the different parties hereto 

                                      -13-
   14
on separate counterparts, each of which, when so executed and delivered, shall
be deemed an original, but all such counterparts shall constitute but one and
the same instrument.
