                        2.         SECURITY INTEREST.

                        2.1.Grant of Security Interest.  To secure the payment
and performance of the Obligations, each Guarantor hereby grants to Agent, for
the benefit of itself and Lenders, a continuing security interest in the
Collateral.

                        2.2.Accounts Receivable.

                        (a)        If requested by Agent, each Guarantor shall
notify Agent immediately of all material disputes or claims by any Account
Debtor and, if reasonably requested by Agent after the occurrence and during
the continuance of a Default, settle or adjust them, or cause them to be
settled or adjusted, at no expense to Agent or Lenders.  If Agent directs after
the occurrence and during the continuance of a Default, no discount or credit
allowance shall be granted thereafter by any Guarantor to any Account Debtor,
other than discounts and trade allowances offered in the ordinary course of
such Guarantor's business.  If requested by Agent, each Guarantor will make
proper entries in its books and records, disclosing the assignment of Accounts
Receivable to Agent, for the benefit of itself and Lenders.

                        (b)        Each Guarantor warrants and covenants that:
(i) all of such Guarantor's Accounts Receivable are and will continue to be
bona fide existing obligations created by the sale of goods, the rendering of
services, or the furnishing of other good and sufficient consideration to such
Guarantor's Account Debtors in the regular course of business; (ii) all
shipping or delivery receipts and other documents furnished or to be furnished
to Agent by such Guarantor upon Agent's request in connection therewith are and
will be genuine; and (iii) none of such Guarantor's Accounts Receivable
identified or included on any schedule, Borrowing Base Certificate or report as
Eligible Accounts Receivable fail at the time so identified or included to
satisfy any of the requirements for eligibility set forth in the definition of
Eligible Accounts Receivable.

                        (c)        Agent is authorized and empowered (which
authorization and power, being coupled with an interest, is irrevocable until
the last to occur of termination of this Agreement and the Guaranty Documents,
termination of the Loan Agreement, and payment and performance in full of all
of the Obligations) at any time in its sole and absolute discretion:

                 (i)      To request, in the name of Agent, Borrower, any
         Guarantor or a third party, confirmation from any Account Debtor or
         party obligated under or with respect to any Collateral of the amount
         shown by the Accounts Receivable or other Collateral to be payable, or
         any other matter stated therein;

                 (ii)     To endorse in any Guarantor's name and to collect any
         chattel paper, checks, notes, drafts, instruments or other items of
         payment tendered to or received by Agent in payment of any Account
         Receivable or other obligation owing to such Guarantor;





                                      -3-
   4
                 (iii)    After the occurrence and during the continuance of a
         Default, to notify, either in Agent's name, Borrower's name or any
         Guarantor's name, and/or to require any Guarantor to notify, any
         Account Debtor or other Person obligated under or in respect of any
         Collateral, of the fact of Agent's Lien thereon, for the benefit of
         itself and Lenders, and of the collateral assignment thereof to Agent,
         for the benefit of itself and Lenders;

                 (iv)     After the occurrence and during the continuance of a
         Default, to direct, either in any Guarantor's name or Agent's name,
         and/or to require any Guarantor to direct, any Account Debtor or other
         Person obligated under or in respect of any Collateral to make payment
         directly to Agent of any amounts due or to become due thereunder or
         with respect thereto; and

                 (v)      After the occurrence and during the continuance of a
         Default, to demand, collect, surrender, release or exchange all or any
         part of any Collateral or any amounts due thereunder or with respect
         thereto, or compromise or extend or renew for any period (whether or
         not longer than the initial period) any and all sums which are now or
         may hereafter become due or owing upon or with respect to any of the
         Collateral, or enforce, by suit or otherwise, payment or performance
         of any of the Collateral either in Agent's own name or in the name of
         any Guarantor.

Under no circumstances shall Agent be under any duty to act in regard to any of
the foregoing matters.  The costs relating to any of the foregoing matters,
including Attorneys' Fees and out-of-pocket expenses, and the cost of any
Depository Account, Assignee Deposit Account, or other bank account or accounts
which may be required hereunder, shall be borne solely by Guarantors whether
the same are incurred by Agent or Guarantors.

                 (d)      Each Guarantor will notify its Account Debtors to
make all payments in respect of such Guarantor's Accounts Receivable directly
to one or more lockbox accounts evidenced by agreements in form and substance
satisfactory to Agent.  All deposits to such lockbox accounts, and all checks,
drafts, cash and other remittances in payment or as proceeds of, or on account
of, any of the Accounts Receivable or other Collateral, shall be deposited in
special bank accounts (the "Depository Accounts") at such banks or financial
institutions as Agent shall consent.  Said proceeds shall be deposited in
precisely the form received except for such Guarantor's endorsement where
necessary to permit collection of items, which endorsement such Guarantor
agrees to make.  Pending such deposit, each Guarantor agrees not to commingle
any such checks, drafts, cash and other remittances with any of its funds or
property, but will hold them separate and apart therefrom and upon an express
trust for Agent, for the benefit of itself and Lenders, until deposit thereof
is made in the Depository Accounts.  All funds in the Depository Accounts at
the end of each Banking Day will be wire transferred or transferred by other
means acceptable to Agent to a special bank account (the "Assignee Deposit





                                      -4-
   5
Account") at Bank of America Illinois over which Agent alone has power of
withdrawal.  Each Guarantor acknowledges that the maintenance of the Assignee
Deposit Account is solely for the convenience of Agent in facilitating its own
operations, and no Guarantor has or shall have any right, title or interest in
the Assignee Deposit Account or in the amounts at any time appearing to the
credit thereof, it being understood that if proceeds in the Assignee Deposit
Account are subsequently transferred to the Demand Deposit Account or operating
account, or a cash collateral account in accordance with Section 2.10(b)(i) of
the Loan Agreement, at the direction of Borrower, one or more of the Guarantors
may be entitled to such proceeds.  Each Guarantor agrees not to maintain any
depository accounts other than Depository Accounts, the Demand Deposit Account
and the Assignee Deposit Account established pursuant to this Section 2.2(d).
Upon the full and final liquidation of all Payment Liabilities, Agent will pay
over to Borrower, on behalf of such Guarantor any excess amounts received by
Agent as payment or proceeds of Collateral, whether received by Agent as a
deposit in the Assignee Deposit Account, contained in a lockbox account or any
Depository Account or received by Agent as a direct payment on any of the sums
due hereunder.

                 (e)      Each Guarantor appoints Agent, or any Person whom
Agent may from time to time designate, as such Guarantor's attorney and
agent-in-fact with power:  (i) after the occurrence and during the continuance
of a Default, to notify the post office authorities to change the address for
delivery of such Guarantor's mail to an address designated by Agent; (ii) to
receive, open and dispose of all mail addressed to such Guarantor, but received
by Agent; (iii) to send requests for verification of Accounts Receivable or
other Collateral to Account Debtors; (iv) to open, under Agent's sole control
(subject, where applicable, to the provisions of the Loan Agreement), an
Assignee Deposit Account, Depository Accounts, Lockbox accounts or other
accounts required under this Agreement for the collection of Accounts
Receivable or other Collateral, if not required contemporaneously with the
execution hereof and if not previously opened by such Guarantor; and (v) to do
all other things which Agent is permitted to do under this Agreement or any
Guaranty Documents or which are necessary to carry out this Agreement and the
Guaranty Documents.  Neither Agent nor any of its directors, officers,
employees or agents will be liable for any acts of commission or omission nor
for any error in judgment or mistake of fact or law, unless the same shall have
resulted from gross negligence or willful misconduct.  The foregoing
appointment and power, being coupled with an interest, is irrevocable until all
Obligations under this Agreement are paid and performed in full and this
Agreement, the Guaranty Documents, and the Loan Agreement are each terminated.
Each Guarantor expressly waives presentment, demand, notice of dishonor and
protest of all instruments and any other notice to which it might otherwise be
entitled.

                 (f)      If any Guarantor's Account Receivable or Contract
Right, in either case in excess of $2,000,000, and designated by Borrower as an
Eligible Account, arises out of a contract with the United States or any state
or local governmental entity, or any department, agency, or instrumentality
thereof, such Guarantor will immediately notify Agent in writing and execute
any instruments and take any steps reasonably required by Agent in order that
all monies due and to become due under such contract shall be assigned to
Agent, for the benefit of itself and Lenders, and notice thereof given to the
applicable government under the Federal Assignment of Claims Act of 1940, as
amended, or other applicable laws or regulations, provided, that with respect
to such Accounts Receivable and Contract Rights in existence on





                                      -5-
   6
the Closing Date or within 90 days thereafter, such steps need not be completed
until 90 days after the Closing Date.  The failure of a Guarantor to comply
with this clause (f) shall not by itself constitute a Default; rather, such
failure will cause the applicable Account Receivable or Contract Right to be
deemed not to be an Eligible Account under the Loan Agreement.

                 (g)      If any Guarantor's Account Receivable or Contract
Right is evidenced by chattel paper or promissory notes, trade acceptances, or
other instruments for the payment of money, such Guarantor will, unless Agent
shall otherwise agree, deliver the originals of same to Agent, appropriately
endorsed to Agent's order and, regardless of the form of such endorsement, such
Guarantor hereby expressly waives presentment, demand, notice of dishonor,
protest and notice of protest and all other notices with respect thereto.

                 2.3.     Inventory.

                 (a)      Each Guarantor warrants and covenants that:  (i) all
of the Inventory is, and at all times shall be, owned by such Guarantor free of
all claims and Liens (except as set forth in Section 5.15 of the Loan
Agreement); and no Guarantor will make any further assignment of any thereof or
create or permit to exist any further Lien thereon, unless approved in writing
by Requisite Lenders, nor permit any of Agent's rights therein to be affected
by any attachment, levy, garnishment or other judicial process.

                 (b)      Neither Agent nor any Lender shall be liable or
responsible in any way for the safekeeping of any Inventory delivered to it, to
any bailee appointed by or for it, to any warehouseman, or under any other
circumstances, other than for losses caused by its gross negligence or willful
misconduct.  Neither Agent nor any Lender shall be responsible for collection
of any proceeds or for losses in collected proceeds held by any Guarantor in
trust for Agent.  Any and all risk of loss for any or all of the foregoing
shall be upon Guarantors.

                 (c)      Any material change in the value or condition of any
Inventory, and any errors discovered in any monthly inventory certificate under
Section 5.1.3 of the Loan Agreement or any other inventory schedule delivered
to Agent and Lenders, shall be reported to Agent promptly.  Each Guarantor
represents and warrants that, as to each schedule of Inventory delivered by
Borrower to Agent or any Lender:

                 (i)      The descriptions, origins, sizes, qualities,
       quantities, weights, and markings of all of such Guarantor's goods
       stated thereon, or on any attachment thereto, are true and correct in
       all respects;

                 (ii)     None of such Guarantor's goods are defective, of
       second quality, used, or goods returned after shipment, except where
       described as such; and

                 (iii)    All of such Guarantor's Inventory not included on 
       such schedule has been previously scheduled.

   7
                 2.4.     Supplemental Documentation.  At Agent's request, each
Guarantor shall execute and deliver, or cause to be executed and delivered, to
Agent, at any time or times hereafter, such agreements, documents, financing
statements, warehouse receipts, bills of lading, notices of assignment of
Accounts Receivable, schedules of Accounts Receivable assigned, and other
written matter necessary or reasonably requested by Agent to perfect and
maintain perfected Agent's security interest in the Collateral, for the benefit
of itself and Lenders (all the above hereinafter referred to as "Supplemental
Documentation"), in form and substance acceptable to Agent, and pay all taxes,
fees and other costs and expenses associated with any recording or filing of
the Supplemental Documentation.  Each Guarantor hereby irrevocably makes,
constitutes and appoints Agent (and all Persons designated by Agent for that
purpose) as such Guarantor's true and lawful attorney (and agent-in-fact)
(which appointment and power, being coupled with an interest, is irrevocable
until the last to occur of termination of this Agreement and the Guaranty
Documents, termination of the Loan Agreement, and payment and performance in
full of all of the Obligations under this Agreement) to sign the name of such
Guarantor on any of the Supplemental Documentation and to deliver any of the
Supplemental Documentation to such Persons as Agent in its sole and absolute
discretion, may elect.  Each Guarantor agrees that a carbon, photographic,
photostatic, or other reproduction of this Agreement or of a financing
statement is sufficient as a financing statement.

                 2.5.     Collateral for the Benefit of Agent and Lenders.  All
Liens granted to Agent hereunder and under the Guaranty Documents and all
Collateral delivered to Agent hereunder and under the Guaranty Documents shall
be deemed to have been granted and delivered to Agent, for the benefit of
itself and Lenders, to secure the Obligations.

                 2.6.     Certain Intellectual Property.  Each Guarantor hereby
grants Agent, for the benefit of Lenders, a world-wide irrevocable license or
other right to use, without charge, labels, rights of use of any name,
tradenames, trademarks and advertising matter, or any assets and property of a
similar nature (collectively, the "Intangible Rights"), as they pertain to the
Collateral, in advertising for sale and selling any Collateral and such
Guarantor's rights under all applicable licenses and license agreements related
to the foregoing shall inure to Agent's benefit.  Such license shall remain in
full force and effect until all of the Obligations  have been repaid in full.
Any transfer of or Lien on the Intangible Rights granted by any Guarantor to
any other Person shall be subject in all respects to Agent's rights granted
hereunder.

                 3.       REPRESENTATIONS AND WARRANTIES.

                 Each Guarantor hereby makes with respect to itself those
representations and warranties to Agent and Lenders applicable to such
Guarantor as are set forth in Section 4 of the Loan Agreement.

                 4.       COVENANTS AND CONTINUING AGREEMENTS.

                 Each Guarantor hereby covenants and agrees that, as long as
any of the Obligations remain outstanding, and even if there shall be no
Obligations outstanding, as long





                                      -7-
   8
as this Agreement, any Guaranty Document or the Loan Agreement remains in
effect, each Guarantor shall comply, with respect to itself, with each of the
covenants set forth in Section 5 of the Loan Agreement.

                 5.       DEFAULT.

                 5.1.     Default.  Each of the following occurrences shall

                 (a)      Breach of Loan Agreement.  The occurrence of any 
         Event of Default under the Loan Agreement.

                 (b)      Breach of Payment Obligations.  Any Guarantor's 
         failure to pay when due any Obligations of such Guarantor under the 
         Guaranty.

         custodian for Borrower, such Guarantor or any other Guarantor, or for
         a substantial part of the property of Borrower, such Guarantor or any
         other Guarantor, or makes a general assignment for the benefit of
         creditors; or, in the absence of such application, consent or
         acquiescence, a trustee, receiver or other custodian is appointed for
         Borrower or any Guarantor or for a substantial part of the property of

         or other proceeding under any bankruptcy or insolvency law, or any
         dissolution or liquidation proceeding, is instituted by or against
         Borrower or any Guarantor; or any warrant of attachment or similar
         legal process is issued against any substantial part of the property
         of Borrower or any Guarantor.

                 5.2.     Effect of Event of Default; Remedies.

described in Section 6.1(e) of the Loan Agreement or one or more Defaults

         that purpose may pursue the same wherever it may be found, and may
         enter into any premises where any of the Collateral may be or is
         supposed to be, and search for, take possession of, remove, keep and
         store any of the Collateral until the same shall be sold or otherwise
         disposed of, and Agent shall have the right to store the same on any
         Guarantor's premises without cost to Agent;

                 (iv)     At Agent's request, each Guarantor will, at such
         Guarantor's expense, assemble the Collateral and make it available to
         Agent at a place or places to be designated by Agent which is
         reasonably convenient to Agent and such Guarantor; and

                 (v)      Agent at its option, and pursuant to notification
         given to a Guarantor as provided for below, may sell any Collateral
         actually or constructively in its possession at public or private sale
         and apply the proceeds thereof as provided below.

                 5.3.     Notice of Disposition of Collateral.  Any
notification of intended disposition of any of the Collateral required by law
shall be deemed reasonably and properly given if given at least ten (10)
calendar days before such disposition.

                 5.4.     Application of Proceeds of Collateral.  Any proceeds
of any disposition by Agent of any of the Collateral may be applied by Agent to
the payment of expenses in connection with the taking possession of, storing,
preparing for sale, and disposition of Collateral, including Attorneys' Fees
and legal expenses, and any balance of such proceeds may be applied by Agent
toward the payment of such of the Obligations, and in such order of
application, as Agent may from time to time elect.

                 5.5.     Care of Collateral.  Agent shall be deemed to have
exercised reasonable care in the custody and preservation of a Guarantor's
Collateral in its possession if it takes such





                                      -9-
   10
action for that purpose as such Guarantor requests in writing, but failure of
Agent to comply with such request shall not, of itself, be deemed a failure to
exercise reasonable care, and no failure of Agent to preserve or protect any
rights with respect to such Collateral against prior parties, or to do any act
with respect to the preservation of such Collateral not so requested by such
Guarantor, shall be deemed a failure to exercise reasonable care in the custody
or preservation of such Collateral.

                 5.6.   Performance of Guarantor's Obligations.  Agent shall 
have the right, but shall not be obligated, to discharge any claims or Liens
against, and any Taxes at any time levied or placed upon any or all Collateral,
including without limitation those arising under statute or in favor of
landlords, taxing authorities, government, public and/or private warehousemen,
common and/or private carriers, processors, finishers, draymen, coopers,
dryers, mechanics, artisans, laborers, attorneys, courts, or others.  Agent may
also pay for maintenance and preservation of Collateral.  Agent may, but is not
obligated to, perform or fulfill any Guarantor's responsibilities under this
Agreement which such Guarantor has failed to perform or fulfill.

                 5.7.   Agent's Rights.  None of the following shall affect the
obligations of any Guarantor to Agent or any Lender under this Agreement or
Agent's right with respect to the remaining Collateral (any or all of which
actions may be taken by Agent at any time, whether before or after an Event of
Default, at its sole and absolute discretion and without notice to any
Guarantor):

                 (a)    acceptance or retention by Agent or any Lender of
         other property or interests in property as security for the
         Obligations, or acceptance or retention of any Obligor(s), in addition
         to Guarantors, with respect to any of the Obligations;

                 (b)    release of its Lien on, or surrender or release of,
         or the substitution or exchange of or for, all or any part of the
         Collateral or any other property securing any of the Obligations
         (including but not limited to any property of any Obligor other than
         Guarantors), or any extension or renewal for one or more periods
         (whether or not longer than the original period), or release,
         compromise, alteration or exchange, of any obligations of any
         guarantor or other Obligor with respect to any Collateral or any such
         property;

                 (c)    extension or renewal for one or more periods (whether
         or not longer than the original period), or release, compromise,
         alteration or exchange of any of the Obligations, or release or
         compromise of any obligation of any Obligor with respect to any of the
         Obligations; or

                 (d)    failure by Agent or any Lender to resort to other
         security or pursue any Person liable for any of the Obligations before
         resorting to the Collateral.

failure or delay on the part of Agent or any Lender in the exercise of any
