Collateral Agent, shall: (i) hold the returned Inventory in trust for the
Collateral Agent; (ii) segregate all returned Inventory from all of its other
property; (iii) dispose of the returned Inventory solely according to the
Collateral Agent's written instructions; and (iv) not issue any credits or
allowances with respect thereto without the Collateral Agent's prior written
consent. All returned Inventory shall be subject to the Collateral Agent's Liens
thereon. Whenever any Inventory is returned, the related Account shall be deemed
ineligible to the extent of the amount owing by the Account Debtor with respect
to such returned Inventory and such returned Inventory shall not be Eligible
Inventory.

     5.3  Inventory. (a) The Debtor will keep its Inventory in good and
marketable condition, except for damaged or defective goods arising in the
ordinary course of the Debtor's business. The Debtor will not, without the prior
written consent of the Collateral Agent, acquire or accept any Inventory on
consignment or approval. The Debtor agrees that all Inventory produced by the
Debtor in the United States of America will be produced in accordance with the
Federal Fair Labor Standards Act of 1938, as amended, and all rules,
regulations, and orders thereunder. The Debtor will conduct a physical count of
the Inventory at least once during each of its fiscal years, and after and
during the continuation of any Event of Default, at such other times as the
Collateral Agent requests. The Debtor will maintain a perpetual inventory
reporting

                                      -10-

<PAGE>

system at all times. The Debtor will not, without the Collateral Agent's written
consent, sell any Inventory on a bill-and-hold, guaranteed sale, sale and
return, sale on approval, consignment, or other repurchase or return basis.

          (b)    In connection with all Inventory financed by a Letter of Credit
with a face amount in excess of $150,000, the Debtor will, at the Collateral
Agent's request, instruct all suppliers, carriers, forwarders, customs brokers,
warehouses or others receiving or holding cash, checks, Inventory, Documents or
Instruments in which the Collateral Agent holds a security interest to deliver
them to the Collateral Agent and/or subject to the Collateral Agent's order, and
if they shall come into the Debtor's possession, to deliver them, upon request,
to the Collateral Agent in their original form. The Debtor shall also, at the
Collateral Agent's request, designate the Collateral Agent as the consignee on
all bills of lading and other negotiable and non-negotiable documents.

     5.4  Equipment. The Debtor shall keep and maintain its Equipment in good
operating condition and repair (ordinary wear and tear excepted) and shall make
all necessary replacements thereof. The Debtor shall not permit any Equipment
that is part of the Collateral to become a fixture with respect to real property
or to become an accession with respect to other personal property with respect
to which real or personal property the Collateral Agent does not have a Lien.
The Debtor will not, without the Collateral Agent's prior written consent, alter
or remove any identifying symbol or number on any of the Debtor's Equipment
constituting Collateral. Except to the extent permitted by the Credit Agreement
and the Note Agreement, the Debtor shall not, without the Collateral Agent's
prior written consent, sell, license, lease as a lessor, or otherwise dispose of
any of the Equipment. The Debtor will not use the Equipment or any of the other
Collateral illegally.

     5.5  Patents, Trademarks and Copyrights. (a) The Debtor shall notify the
Collateral Agent immediately if it knows or has reason to know that any
application or registration relating to any patent, trademark or copyright (now
or hereafter existing) will be abandoned or dedicated, or of any material
adverse determination or development (including the institution of, or any such
determination or development in, any proceeding in the United States Patent and
Trademark Office, the United States Copyright Office or any court) regarding the
Debtor's ownership of any patent, trademark or copyright, its right to register
the same, or to keep and maintain the same.

          (b)    In no event shall the Debtor, either directly or through any
agent, employee, licensee or designee, file an application for the registration
of any patent, trademark or copyright with the United States Patent and
Trademark Office, the United States Copyright Office or any similar office or
agency without giving the Collateral Agent prior written notice thereof, and,
upon request of the Collateral Agent, the Debtor shall execute and deliver any
and all such agreements, assignments and security agreements as the Collateral
Agent may reasonably request to evidence the Collateral Agent's Lien on such
patent, trademark or copyright, and the General Intangibles of the Debtor
relating thereto or represented thereby.

          (c)    The Debtor shall take all actions necessary or advisable, in
the exercise of its prudent business judgment, to maintain and pursue each
application, to obtain the relevant

                                      -11-

<PAGE>

registration and to maintain the registration of each of the patents, trademarks
and copyrights (now or hereafter existing), including the filing of applications
for renewal, affidavits of use, affidavits of noncontestability and opposition
and interference and cancellation proceedings.

          (d)    In the event that any of the patent, trademark or copyright
Collateral is infringed upon, or misappropriated or diluted by a third party,
the Debtor shall notify the Collateral Agent promptly after the Debtor learns
thereof. The Debtor shall, unless it shall reasonably determines that such
patent, trademark or copyright Collateral is not material to the conduct of its
business or operations, take such actions as the Debtor shall deem appropriate
to protect such patent, trademark or copyright Collateral.

     5.6  Maintenance of Records. The Debtor will keep and maintain, at its own
cost and expense, in a manner consistent with past practice, complete and
current records of the Collateral owned by it, including, but not limited to, a
record of all shipments received, deliveries made, contracts performed, payments
received, credits granted thereon and other dealings therewith. The Debtor shall
timely provide the Collateral Agent with all such collateral reports as are
required by the Credit Agreement and the Note Agreement, and all such additional
reports as the Collateral Agent shall reasonably require. These reports shall be
in the form previously provided to the Collateral Agent for its review or in
form and detail as is reasonably satisfactory to the Collateral Agent. The
Debtor will use all reasonable efforts to protect its records and books
pertaining to any Collateral against fire, theft, loss or any other manner of
destruction or loss. Such protection will consist of such protective means and
devices as from time to time reasonably deemed necessary by the Collateral
Agent. If the Debtor maintains its records of Accounts on a computer, it will
maintain backup copies of such records, updated at reasonable intervals.

     5.7  Inspection and Delivery of Collateral, Books and Records. The
Collateral Agent or the Secured Parties, or any of them, or their respective
agents, may at any reasonable time and from time to time and, if no Event of
Default has occurred, upon reasonable prior notice, inspect the Collateral, and
the books and records of the Debtor pertaining thereto. Not more frequently than
one (1) time during each calendar year if no Event of Default has occurred and
is continuing (there being no such limitation if any Event of Default has
occurred and is continuing), the Debtor shall, at its own expense and cost,
deliver or make available, at the Collateral Agent's election, books and records
pertaining to the Accounts (including chattel paper) to the Collateral Agent, or
any designated agent of the Collateral Agent, at such time and place as the
Collateral Agent may reasonably request.

     5.8  Expenses. The Debtor shall be liable for, and agrees to pay the
Collateral Agent on demand, any and all reasonable expenses incurred or paid by
the Collateral Agent or the Secured Parties, or any of them, in protecting or
enforcing their respective rights under this Security Agreement, including,
without limitation, reasonable attorneys' fees, whether incurred in collecting
specific Accounts or otherwise. If the Debtor shall fail, in violation of the
terms of the Credit Agreement or the Note Agreement, to discharge taxes, liens,
security interests or other encumbrances on the Collateral, other than Permitted
Liens, or to repair any damage to the Collateral, or to maintain or preserve the
Collateral or to maintain adequate insurance on the Collateral, in each case
within twenty (20) days after written notice from the Collateral Agent, the
Collateral Agent may, at its option, discharge such taxes, liens, security
interests or other

                                      -12-

<PAGE>

encumbrances on or in the Collateral, pay for the repair or damage to the
Collateral, pay for the maintenance and preservation of the Collateral,
and/or pay for insurance on the Collateral. The Debtor agrees to reimburse the
Collateral Agent on demand for any payments so made and, until such
reimbursement, to pay interest thereon at a fluctuating rate of interest equal
to the Default Rate applicable to the Revolving Loans from the date of the
payment until reimbursement therefor, which reimbursement and interest shall be
a part of the Obligations. Any payment made or other action taken by the
Collateral Agent under this Section 5.8 shall be without prejudice to any right
to assert an Event of Default hereunder and to proceed thereafter as herein
provided.

     5.9  Insurance. The Debtor will continuously insure the Collateral with a
responsible company or companies reasonably satisfactory to the Collateral Agent
against fire (with extended coverage) in the full insurable value of the
Collateral, and against such other casualties and in such amounts and with such
deductibles as are usually carried by owners of similar businesses and
properties in the same general areas in which the Debtor operates. The insurance
policy (or policies) shall have attached thereto a standard loss payable clause,
without contribution, in favor of the Collateral Agent as agent for the Secured
Parties as its interest may appear, and shall otherwise be in form reasonably
acceptable to the Collateral Agent, and the Debtor will cause such policy (or
policies) to provide that it (they) may not be canceled without thirty (30)
days' prior written notice to the Collateral Agent. The Debtor will deliver to
the Collateral Agent as agent for the Secured Parties evidence of the renewal or
continuation of insurance at least ten (10) days before the expiration of the
existing insurance. The Debtor hereby assigns to the Collateral Agent as agent
for the Secured Parties any return of unearned premiums which may be due upon
cancellation of any such policy or policies for any reason whatsoever and, upon
the occurrence of any Event of Default and during the continuance thereof,
directs the insurer(s) to pay to the Collateral Agent as agent for the Secured
Parties any amounts so due.

     5.10 Damage or Loss and Replacement. (a) The Debtor shall promptly notify
the Collateral Agent of any fire, theft, water damage, vandalism or other damage
to or loss of any Inventory or Equipment to the extent that the uninsured
portion of such damaged or lost Inventory or Equipment is in excess of $250,000.
In the case of any loss, damage to or destruction of the Inventory or Equipment
or any part thereof, the Debtor, whether or not the insurance proceeds, if any,
received on account of such damage or destruction shall be sufficient for that
purpose, at the Debtor's cost and expense, will promptly repair or replace the
Inventory or Equipment so lost, damaged or destroyed.

          (b)    In the event that the Debtor or the Collateral Agent shall
receive any proceeds of insurance with respect to Inventory, provided no Default
or Event of Default then exists, (a) the Debtor shall pay to the Collateral
Agent, or the Collateral Agent shall retain, as applicable, an amount of such
proceeds equal to the balance then outstanding under the Revolving Credit Loan
Obligations, which amount the Collateral Agent shall promptly pay to BB&T-VA for
application to the Revolving Credit Loan Obligations, and the Debtor shall be
entitled to retain, or the Collateral Agent shall pay to the Debtor, as
applicable, any such excess insurance proceeds or (b) if there is no balance
then outstanding under the Revolving Credit Loan Obligations, then the Debtor
shall be entitled to retain, or the Collateral Agent shall pay to the Debtor, as
applicable, all such proceeds of insurance with respect to Inventory.

                                      -13-

<PAGE>

          (c)    In the event the Debtor shall receive any proceeds of insurance
with respect to the Equipment in excess of $1,000,000 in the aggregate in any
fiscal year of the Debtor, the Debtor shall immediately pay over such proceeds
in excess of $1,000,000 to the Collateral Agent. Insurance proceeds received by
the Collateral Agent under the provisions hereof or under any policy or policies
of insurance covering the Equipment or any part thereof pursuant to the terms
hereof in excess of $1,000,000 in the aggregate in any fiscal year of the Debtor
shall be applied to the reduction of, or otherwise held as security for, the
Secured Obligations (whether or not then due); provided, however, that the
Collateral Agent agrees to release such insurance proceeds to the Debtor for the
replacement, repair or restoration of the portion of the Equipment lost, damaged
or destroyed if, but only if, (i) at the time of release no Default or Event of
Default exists, (ii) a written request for such release is received from the
Debtor within thirty (30) calendar days of receipt of, or in the event received
by the Collateral Agent notice of the Collateral Agent's receipt of, such
insurance proceeds and (iii) the Debtor provides the Collateral Agent purchase
orders or invoices for replacement property for, or for the repair or
restoration of, the Equipment that was lost, damaged or destroyed giving rise to
the payment of such insurance proceeds within 210 days of the occurrence of such
loss, damage or destruction. Notwithstanding the foregoing, if, following the
application of insurance proceeds to replace, repair or restore Equipment as
provided in this Section 5.10(c), there is an amount of such proceeds which is
less than $50,000 remaining, provided that no Default or Event of Default shall
have occurred and be continuing, the Collateral Agent shall return such amount
to the Debtor.

     5.11 Further Assurances. Subject to the provisions of Section 5.1(a)
hereof, the Debtor will from time to time, at the sole expense of the Debtor,
promptly execute, deliver, file and record (as appropriate) all further
instruments and documents, and take all further action as the Collateral Agent
or the Secured Parties, or any of them, may reasonably deem necessary or prudent
in order to perfect, continue and protect the security interests granted hereby
or to enable the Collateral Agent or the Secured Parties, or any of them, to
exercise and enforce its rights and remedies hereunder with respect to the
Collateral or any part thereof.

SECTION 6 - SALES AND COLLECTIONS

     6.1  Processing and Sales of Inventory. So long as no Event of Default
shall have occurred and be continuing and the Collateral Agent shall not have
notified the Debtor to the contrary, the Debtor shall have the right in the
regular course of its business to process and sell the Inventory. The security
interests granted hereunder to the Collateral Agent as agent for the Secured
Parties shall attach to all proceeds of all sales, leases, or other dispositions
of the Inventory.

     6.2  Inventory Controls. Upon the occurrence and during the continuation of
any Event of Default, the Collateral Agent or its agents may secure all
entrances to those parts of the premises of the Debtor in which any Inventory is
stored and keep such entrances locked or otherwise sealed or institute such
other control measures with respect to the movement of Inventory as the
Collateral Agent may deem necessary or prudent, subject to the rights of third
parties under the Leases.

                                      -14-

<PAGE>

     6.3  Collection of Accounts. The Collateral Agent as agent for the Secured
Parties hereby authorizes the Debtor to collect and dispose of the proceeds of
the Accounts, which authority the Collateral Agent may curtail or terminate at
any time following the occurrence and during the continuance of any Event of
Default. After such authority has been curtailed or terminated, the Debtor
shall, upon receipt of all checks, drafts, cash, and other remittances in
payment of or on account of the Accounts, deposit the same in a special account
designated by the Collateral Agent, over which account the Collateral Agent as
agent for the Secured Parties alone shall have the power of withdrawal (the
"Collection Account"). The remittance of the proceeds of such Accounts shall
not, however, constitute payment or liquidation of such Accounts until the
Collateral Agent as agent for the Secured Parties shall receive good funds for
such proceeds.

     For purposes of computing interest, the Collateral Agent shall treat
deposited checks, drafts and other items as collected in accordance with the
Collateral Agent's normal availability schedule, but in doing so the Collateral
Agent is not agreeing that such funds have in fact been paid, nor is the
Collateral Agent as agent for the Secured Parties waiving any right it may have
to charge back returned items to the Debtor and to collect interest on such
charged-back items. Funds placed in the Collection Account shall be held by the
Collateral Agent as agent for the Secured Parties as security for the
Obligations. These proceeds shall be deposited in precisely the form received,
except for the endorsement of the Debtor where necessary to permit collection of
items, which endorsement the Debtor agrees to make, and which endorsement the
Collateral Agent is also hereby authorized to make on behalf of the Debtor.
Pending such deposit, the Debtor agrees that it will not commingle any such
checks, drafts, cash or other remittances with any funds or other property of
the Debtor but will hold them separate and apart therefrom, and upon an express
trust for the Collateral Agent until deposit thereof is made in the Collection
Account. The Collateral Agent as agent for the Secured Parties will from time to
time apply the funds on deposit in the Collection Account against the
Obligations in such order of application as is required by the Intercreditor
Agreement.

SECTION 7 - POWER OF ATTORNEY

     Effective upon the occurrence and during the continuance of any Event of
Default, the Debtor hereby appoints the Collateral Agent and the Collateral
Agent's designee as the Debtor's attorney-in-fact, with full power of
substitution: (a) to endorse the Debtor's name on any checks, notes,
acceptances, money orders, or other forms of payment or security that come into
the Collateral Agent's or any Secured Party's possession; (b) to sign the
Debtor's name on any invoice, bill of lading, warehouse receipt or other
negotiable or non-negotiable Document constituting Collateral, on drafts against
customers, on assignments of Accounts, on notices of assignment, financing
statements and other public records and to file any such financing statements by
electronic means with or without a signature as authorized or required by
applicable law or filing procedure; (c) to execute loss claims and other
applications for payment of benefits under any insurance policy covering any of
the Collateral in the name of the Debtor or the Collateral Agent, to receive all
monies and endorse drafts, checks, and other instruments for the payment of any
proceeds of any insurance or in order to collect any return of unearned
premiums, (d) to notify the post office authorities to change the address for
delivery of the Debtor's mail to an address designated by the Collateral Agent
and to receive, open and dispose of all mail addressed to the Debtor; (e) to
send requests for verification of Accounts to customers

                                      -15-

<PAGE>

or Account Debtors; (f) to complete in the Debtor's name or the Collateral
Agent's name, any order, sale or transaction, obtain the necessary Documents in
connection therewith, and collect the proceeds thereof; (g) to clear Inventory
through customs in the Debtor's name, the Collateral Agent's name or the name of
the Collateral Agent's designee, and to sign and deliver to customs officials
powers of attorney in the Debtor's name for such purpose; (h) to the extent that
the Debtor's authorization given in Section 5.1(d) of this Security Agreement is
not sufficient (which authorization in Section 5.1(d) is effective, and which
powers under Section 5.1(d) may be exercised by the Collateral Agent, before the
occurrence of an Event of Default), to file such financing statements with
respect to this Security Agreement, with or without the Debtor's signature, or
to file a photocopy of this Security Agreement in substitution for a financing
statement, as the Collateral Agent may deem appropriate and to execute in the
Debtor's name such financing statements and amendments thereto and continuation
statements which may require the Debtor's signature; and (i) to do all things
necessary to carry out the terms of this Security Agreement. The Collateral
Agent shall not be obligated to do any of the acts or exercise any of the powers
hereinabove authorized, but, if the Collateral Agent elects to do any such act
or exercise any such power, unless the Collateral Agent is guilty of gross
negligence or willful misconduct in the exercise of such power, it shall not be
accountable to the Debtor for more than it actually receives as a result of such
exercise of power, and, in any event, none of the Collateral Agent or any of the
Secured Parties, nor any of their respective attorneys, will be liable for any
acts or omissions or for any error of judgment or mistake of fact or law except
for their gross negligence or willful misconduct. This appointment shall be
deemed a power coupled with an interest, shall be irrevocable, and shall not
terminate until the Obligations have been fully satisfied, the Credit Agreement
has been terminated and the Notes (as defined in the Note Agreement) have been
paid in full under the Note Agreement. The Debtor hereby ratifies and approves
all acts of such attorney-in-fact.

SECTION 8 - NO LIABILITY

          (a)    The Debtor assumes all responsibility and liability arising
from or relating to the use, sale, license or other disposition of the
Collateral. The Obligations shall not be affected by any failure of the
Collateral Agent or any of the Secured Parties to take any steps to perfect the
Collateral Agent's Liens or to collect or realize upon the Collateral, nor shall
loss of or damage to the Collateral release the Debtor from any of the
Obligations. Following the occurrence and during the continuation of any Event
of Default, the Collateral Agent may (but shall not be required to), without
notice to or consent from the Debtor, sue upon or otherwise collect, extend the
time for payment of, modify or amend the terms of, compromise or settle for
cash, credit, or otherwise upon any terms, grant other indulgences, extensions,
renewals, compositions, or releases, and take or omit to take any other action
with respect to the Collateral, any security therefor, any agreement relating
thereto, any insurance applicable thereto, or any Person liable directly or
indirectly in connection with any of the foregoing, without discharging or
otherwise affecting the liability of the Debtor for the Obligations, or any
other agreement now or hereafter existing between the Collateral Agent and/or
any Secured Party and the Debtor.

          (b)    It is expressly agreed by the Debtor that, anything herein to
the contrary notwithstanding, the Debtor shall remain liable under each of its
contracts and each of its licenses to observe and perform all the conditions and
obligations to be observed and performed by it thereunder. None of the
Collateral Agent or any of the Secured Parties shall have any

                                      -16-

<PAGE>

obligation or liability under any contract or license by reason of or arising
out of this Security Agreement or the granting herein of a Lien thereon or the
receipt by the Collateral Agent or any Secured Party of any payment relating to
any contract or license pursuant hereto. None of the Collateral Agent or any
Secured Party shall be required or obligated in any manner to perform or fulfill
any of the obligations of the Debtor under or pursuant to any contract or
license, or to make any payment, or to make any inquiry as to the nature or the
sufficiency of any payment received by it or the sufficiency of any performance
by any party under any contract or license, or to present or file any claims, or
to take any action to collect or enforce any performance or the payment of any
amounts which may have been assigned to it or to which it may be entitled at any
time or times.

          (c)    The Collateral Agent may at any time after any Event of Default
shall have occurred and be continuing (or if any rights of set-off (other than
set-offs against an Account arising under the contract giving rise to the same
Account) or contra accounts may be asserted with respect to the following),
without prior notice to the Debtor, notify Account Debtors, and other Persons
obligated on the Collateral that the Collateral Agent has a security interest
therein, and that payments shall be made directly to the Collateral Agent, for
the benefit of the Secured Parties. Upon the request of the Collateral Agent,
the Debtor shall so notify Account Debtors, and other Persons obligated on
Collateral. Once any such notice has been given to any Account Debtor or other
Person obligated on the Collateral, the Debtor shall not give any contrary
instructions to such Account Debtor or other Person without the Collateral
Agent's prior written consent.

          (d)    After the occurrence and during the continuance of any Event of
Default, the Collateral Agent may at any time in the Collateral Agent's own name
or in the name of the Debtor communicate with Account Debtors, parties to
contracts and agreements to which the Debtor is a party, and obligors in respect
of Instruments to verify with such Persons, to the Collateral Agent's
satisfaction, the existence, amount and terms of Accounts, contracts and
agreements, payment intangibles, Instruments or Chattel Paper. If any Event of
Default shall have occurred and be continuing, the Debtor, at its own expense,
shall cause the independent certified public accountants then engaged by the
Debtor to prepare and deliver to the Collateral Agent and each of the Secured
Parties at any time and from time to time promptly upon the Collateral Agent's
request the following reports with respect to the Debtor: (i) a reconciliation
of all Accounts; (ii) an aging of all Accounts; (iii) trial balances; and (iv) a
test verification of such Accounts as the Collateral Agent may request. The
Debtor, at its own expense, shall deliver to the Collateral Agent the results of
each physical verification, if any, which the Debtor may in its discretion have
made, or caused any other Person to have made on its behalf, of all or any
portion of its Inventory.

          (e)    The Collateral Agent shall use reasonable care with respect to
the Collateral in its possession or under its control. The Collateral Agent
shall not have any other duty as to any Collateral in its possession or control
or in the possession or control of any agent or nominee of the Collateral Agent,
or any income thereon or as to the preservation of rights against prior parties
or any other rights pertaining thereto.

                                      -17-

<PAGE>

SECTION 9 - DEFAULT AND REMEDIES

          (a)    In addition to all other rights and remedies granted to it
under this Security Agreement, the Credit Agreement, the other Loan Documents,
the Note Agreement, and under any other instrument or agreement securing,
evidencing or relating to any of the Obligations, upon the occurrence of any
Event of Default, the Collateral Agent, as agent for the Secured Parties, may,
subject to the provisions of the Intercreditor Agreement, exercise all rights
and remedies of a secured party under the UCC. Without limiting the generality
of the foregoing, the Debtor expressly agrees that in any such event the
Collateral Agent, without demand of performance or other demand, advertisement
or notice of any kind (except the notice specified below of time and place of
public or private sale) to or upon the Debtor or any other Person (all and each
of which demands, advertisements and notices are hereby expressly waived to the
maximum extent permitted by the UCC and other applicable law), may forthwith
enter upon the premises of the Debtor where any Collateral is located through
self-help, without judicial process, without first obtaining a final judgment or
giving the Debtor or any other Person notice and opportunity for a hearing on
the Collateral Agent's claim or action and may collect, receive, assemble,
process, appropriate and realize upon the Collateral, or any part thereof, and
may forthwith sell, lease, license, assign, give an option or options to
purchase, or sell or otherwise dispose of and deliver the Collateral (or
contract to do so), or any part thereof, in one or more parcels at a public or
private sale or sales, at any exchange at such prices as it may deem acceptable,
for cash or on credit or for future delivery without assumption of any credit
risk. The Collateral Agent shall have the right upon any such public sale or
sales and, to the extent permitted by law, upon any such private sale or sales,
to purchase for the benefit of the Collateral Agent and the Secured Parties the
whole or any part of the Collateral so sold, free of any right or equity of
redemption, which equity of redemption the Debtor hereby releases. Such sales
may be adjourned and continued from time to time with or without notice. The
Collateral Agent shall have the right to conduct such sales on the Debtor's
premises or elsewhere and shall have the right to use the Debtor's premises
without charge for such time or times as the Collateral Agent deems necessary or
advisable. Expenses of retaking, holding, preparing for sale, selling and the
like shall include the reasonable attorneys' fees and legal expenses of the
Collateral Agent and the Secured Parties, and each of them.

          (b)    After the occurrence and during the continuance of any Event of
Default, the Debtor further agrees, at the Collateral Agent's request, to
assemble the Collateral and make it available to the Collateral Agent at a place
or places designated by the Collateral Agent which are reasonably convenient to
the Collateral Agent and the Debtor, whether at the Debtor's premises or
elsewhere. Until the Collateral Agent is able to effect a sale, lease, or other
disposition of Collateral, the Collateral Agent shall have the right to hold or
use Collateral, or any part thereof, to the extent that it deems appropriate for
the purpose of preserving the Collateral or its value or for any other purpose
deemed appropriate by the Collateral Agent. The Collateral Agent shall have no
obligation to the Debtor to maintain or preserve the rights of the Debtor as
against third parties with respect to Collateral while Collateral is in the
possession of the Collateral Agent. The Collateral Agent may, if it so elects,
seek the appointment of a receiver or keeper to take possession of Collateral
and to enforce any of the Collateral Agent's remedies (for the benefit of the
Collateral Agent and the Secured Parties), with respect to such appointment
without prior notice or hearing as to such appointment. The Collateral Agent
shall apply the net proceeds of any such collection, recovery, receipt,
appropriation, realization or sale

                                      -18-

<PAGE>

to the Obligations in such order of application as is required by the
Intercreditor Agreement, and only after so paying over such net proceeds, and
after the payment by the Collateral Agent of any other amount required by any
provision of law, need the Collateral Agent account for the surplus, if any, to
the Debtor. To the maximum extent permitted by applicable law, the Debtor waives
all claims, damages, and demands against the Collateral Agent and each Secured
Party arising out of the repossession, retention or sale of the Collateral
except such as arise solely out of the gross negligence or willful misconduct of
the Collateral Agent or any Secured Party as finally determined by a court of
competent jurisdiction. The Collateral Agent will give the Debtor reasonable
notice of the time and place of any public sale of the Collateral or any part
thereof or of the time after which any private sale or any other intended
disposition thereof is to be made. The Debtor and the Collateral Agent agree
that the requirements of reasonable notice shall be met if such notice is given
to the Debtor at the address of the Debtor specified in Section 10.2 of this
Security Agreement (or such other address that the Debtor may provide to the
Collateral Agent in writing) at least ten (10) days before the time of the sale
or disposition, but nothing contained herein shall be construed to mean that any
other notice or a shorter period of time does not constitute reasonable notice
for the sale of the Collateral or any part thereof. The Debtor shall remain
liable for any deficiency if the proceeds of any sale or disposition of the
Collateral are insufficient to pay all Obligations, including any attorneys'
fees or other expenses incurred by the Collateral Agent or any Secured Party to
collect such deficiency.

          (c)    After the occurrence and during the continuance of any Event of
Default, the Collateral Agent shall have the right to enter upon the premises of
the Debtor at any time for the purpose of reducing to possession the Accounts
(including Chattel Paper) and all cash or non-cash proceeds thereof, for the
purpose of taking possession of and using the current version of the Debtor's
accounts receivable computer software, and/or for the purpose of inspecting the
Inventory and Equipment and inspecting and/or auditing the books, records and
procedures of the Debtor. The Collateral Agent may deduct its expenses in
collecting the Accounts from the proceeds applicable to the Obligations. Such
expenses shall include, without limitation, the costs of posting transactions to
the books of the Debtor and performing such other bookkeeping and accounting
tasks as the Collateral Agent may deem appropriate to collect any Account.

          (d)    Except as otherwise specifically provided herein, the Debtor
hereby waives presentment, demand, protest or any notice (to the maximum extent
permitted by applicable law) of any kind in connection with this Security
Agreement or any Collateral.

          (e)    For the purpose of enabling the Collateral Agent to exercise
rights and remedies under this Section 9 (including, without limiting the terms
of this Section, in order to take possession of, hold, preserve, process,
assemble, prepare for sale, market for sale, sell or otherwise dispose of
Collateral) at such time as the Collateral Agent shall be lawfully entitled to
exercise such rights and remedies, the Debtor hereby grants to the Collateral
Agent, for the benefit of the Collateral Agent and the Secured Parties, an
irrevocable, nonexclusive license (exercisable without payment of royalty or
other compensation to the Debtor) to use, license or sublicense any Proprietary
Rights now owned or hereafter acquired by the Debtor, and wherever the same may
be located, and including in such license access to all media in which any of
the licensed items may be recorded or stored and to all computer software and
programs used for the compilation or printout thereof.

     10.3 Applicable Law. This Security Agreement shall be construed in
accordance with and governed by the laws of the Commonwealth of Virginia, except
as otherwise required by mandatory provisions of law and except to the extent
that remedies provided by the laws of any jurisdiction other than Virginia are
governed by the laws of such jurisdiction.

     10.4 Arbitration; Submission to Jurisdiction; Waiver of Jury Trial.

          (a)    Upon demand of any party hereto, whether made before or after
institution of any judicial proceeding, any claim or controversy arising out of
or relating to this Security Agreement or any other Loan Documents between the
parties hereto (a "Dispute") shall be resolved by binding arbitration conducted
under and governed by the Commercial Financial Disputes Arbitration Rules (the
"Arbitration Rules") of the American Arbitration Association (the "AAA") and the
Federal Arbitration Act. Disputes may include, without limitation, tort claims,
counterclaims, disputes as to whether a matter is subject to arbitration, claims
brought as class actions, or claims arising from documents executed in the
future. A judgment upon the award may be entered in any court having
jurisdiction. Notwithstanding the foregoing, this arbitration provision does not
apply to disputes under or related to swap agreements.

          (b)    All arbitration hearings shall be conducted in the City of
Richmond, Virginia. A hearing shall begin within 90 days of demand for
arbitration and all hearings shall be concluded within 120 days of demand for
arbitration. These time limitations may not be extended unless a party shows
cause for extension and then for no more than a total of 60 days. The expedited
procedures set forth in Rule 51 et seq. of the Arbitration Rules shall be
applicable to claims of less than $1,000,000. Arbitrators shall be licensed
attorneys selected from the Commercial Financial Dispute Arbitration Panel of
the AAA. The parties do not waive applicable federal or state substantive law
except as provided herein.

                                      -21-

<PAGE>

          (c)    Notwithstanding the preceding binding arbitration provisions,
the parties agree to preserve, without diminution, certain remedies that any
party may exercise before or after an arbitration proceeding is brought. The
parties shall have the right to proceed in any court of proper jurisdiction or
by self-help to exercise or prosecute the following remedies, as applicable: (i)
all rights to foreclose against any real or personal property or other security
by exercising a power of sale or under applicable law by judicial foreclosure,
including a proceeding to confirm the sale; (ii) all rights of self-help,
including peaceful occupation of real property and collection of rents, setoff
and peaceful possession of personal property; and (iii) obtaining provisional or
ancillary remedies, including injunctive relief, sequestration, garnishment,
attachment, appointment of receiver and filing an involuntary bankruptcy
proceeding. Any claim or controversy with regard to the parties' entitlement to
such remedies is a Dispute.

          (d)    Each party agrees that it shall not have a remedy of punitive
or exemplary damages against the other in any Dispute and hereby waives any
right or claim to punitive or exemplary damages it may have now or which may
arise in the future in connection with any Dispute, whether the Dispute is
resolved by arbitration or judicially.

          (e)    TO THE FULLEST EXTENT PERMITTED BY LAW, THE PARTIES HERETO
HEREBY IRREVOCABLY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO
ANY DISPUTE.

     10.5 Severability; Modification. If any provision hereof is invalid or
unenforceable in any jurisdictions, then, to the fullest extent permitted by
law, (a) the other provisions hereof shall remain in full force and effect in
such jurisdiction; and (b) the invalidity or unenforceability of any provision
hereof in any jurisdiction shall not affect the validity or enforceability of
such provisions in any other jurisdiction. No modification, amendment or waiver
of any provision of this Security Agreement, nor consent to any departure by the
Debtor therefrom, shall in any event be effective unless the same shall be in
writing, made in accordance with the Intercreditor Agreement, and signed by the
Collateral Agent and the Debtor, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice to or demand upon the Debtor in any case shall entitle the Debtor to any
other or further notice or demand in the same or similar circumstances.

     10.6 Execution in Counterparts. This Security Agreement may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed to be
an original and all of which taken together shall constitute but one and the
same instrument.

     10.7 Obligations Joint and Several. Each and every obligation of the Debtor
contained in this Security Agreement shall be the joint and several obligations
of TREX Company, LLC and Trex Company, Inc.

                                      -22-
