SECTION 3. The Security Interests

      (a) In order to secure the full and punctual payment of the Secured

      hereof,

provided however, that the foregoing security interest shall not include a
security interest in any Collateral comprised of Intellectual Property of the
Borrower or any of its Subsidiaries (the "Intellectual Property Collateral") if
the granting of the security interest therein by the Borrower to the Lender is
prohibited by any requirement of law or by the terms and provisions of the
written agreement, document or instrument creating or evidencing such
Intellectual Property Collateral or rights related thereto and provided further,
that if and when the prohibition which prevents the granting by the Borrower to
the Lender of a security interest in such Intellectual

security interest in such Intellectual Property Collateral, as the case may be,
and that, notwithstanding anything set forth herein to the contrary, the Lender
will be deemed to have, and at all times from and after the date hereof to have

of business, or the location of its chief executive office or its federal tax
identification number, or (ii) the locations where it keeps or holds any
Collateral or records relating thereto from the applicable locations described
in the perfection certificate delivered by the Borrower to the Lender, or (iii)
its name, idenity or corporate structure in any manner, in each case without
giving the Lender thirty (30) day prior written notice thereof. In the event of
any such change, the Borrower shall, at its cost and expense, cooperate with the
Lender and cause to be filed or recorded additional financing statements,
amendments or supplements to existing financing statements, continuation
statements or other documents required to be recorded or filed in order to
perfect and protect the Security Interest. The Borrower shall not, in any event,
make any change if such change would cause the Security Interests in any
Collateral to lapse or cease to be perfected.

      (b) The, Borrower will, from time to time, at its expense, execute,
deliver, file and record any statement, assignment, instrument, document,
agreement or other paper and take any other action (including, without
limitation, collateral assignments of trademarks, copyright mortgages and any
filings of financing or continuation statements under the UCC) that the Lender
may from time to time reasonably determine to be necessary or desirable in order
to create, preserve, upgrade in rank (to the extent required hereby), perfect,
confirm or validate the Security Interests or to enable the Lender to obtain the
full benefits of this Agreement, or to enable the Lender to exercise and enforce
any of its rights, powers and remedies hereunder with respect to any of the
Collateral. At the request of the Lender, the Borrower will use reasonable
efforts to obtain the consent of any Person that is necessary or desirable to
effect the pledge hereunder of any right, title, claims and benefits now owned
or hereafter acquired by the Borrower in and to any Gneral Intangible. To the
extent permitted by law, the Borrower hereby authorizes the Lender to execute
and file financing statements or continuation statements without the Borrower's
signature appearing thereon. The Borrower agrees that a carbon, photographic or
other reproduction of this Agreement or of a financing statement is sufficient
as a financing statement. The Borrower shall pay the costs of, or incidental to,
any recording or filing of any financing or continuation statements concerning
the Collateral.

      (c) If any Collateral is at any time in the possession or control of any
warehouseman, bailee or of the Borrower's agents or processors, the Borrower
shall, upon the request of the Lender, notify such warehouseman, bailee, agent
or processor of the Security Interests created


                                        6

<PAGE>

hereby and to hold all such Collateral for the Lender's account subject to the
Lender's instructions.

      (d) The Borrower shall keep complete and accurate books and records
relating to the Collateral.

      (e) The Borrower will promptly deliver and pledge each Instrument to the
Lender, appropriately endorsed to the Lender without recourse, provided that so
long as no Event of Default shall have occurred and be continuing, the Borrower
may retain for collection in the ordinary course any Instruments received by
them in the ordinary course of business and the Lender shall, promptly upon
request of the Borrower, make appropriate arrangements for making any other
Instrument pledged by the Borrower available to it for purposes of presentation,
collection or renewal (any such arrangement to be effected, to the extent deemed
appropriate to the Lender, against trust receipt or like document).

      (f) The Borrower shall use its best efforts to cause to be collected from
its account debtors, as and when due, any and all amounts owing under or on
account of each Account (including, without limitation, Accounts which are
delinquent, such Accounts to be collected in accordance with lawful collection
procedures and the Borrower's standard procedures) and apply forthwith upon
receipt thereof all such amounts as are so collected to the outstanding balance
of such Account, except that, unless an Event of Default has occurred and is
continuing and the Lender is exercising its rights hereunder to collect
Accounts, the Borrower may allow in the ordinary course of business as
adjustments to amounts owing under its Accounts (i) an extension or renewal of
the time or times of payment, or settlement for less than the total unpaid
balance, which the Borrower finds appropriate in accordance with prudent
business judgment and (ii) a refund or credit due as a result of returned or
damaged merchandise, all in accordance with the Borrower's ordinary course of
business consistent with their historical collection practices. The costs and
expenses (including, without limitation, attorney's fees) of collection, whether
incurred by the Borrower or the Lender, shall be borne by the Borrower.

      (g) Upon the occurrence and during the continuance of any Event of
Default, upon the request of the Lender, the Borrower will promptly notify (and
the Borrower hereby authorizes the Lender so to notify) each account debtor in
respect of any Account or Instrument that such Collateral has been assigned to
the Lender hereunder, and that any payments due or to become due in respect of
such Collateral are to be made directly to the Lender or any designee specified
by the Lender. Following such request of the Lender, the Borrower shall hold all
proceeds from collection of Accounts as trustee for the Lender (without
commingling the same with other funds of the Borrower) and shall turn the same
over to the Lender immediately upon receipt in the identical form received (duly
endorsed by the Borrower to the Lender, if required). The Lender shall apply the
proceeds of such collections received by it to the Secured Obligations in
accordance with Section 8 of this Agreement. The application of the proceeds of
such collections shall be conditional upon the final payment in cash of the
items so collected. If any item is not so paid or the Lender is required for any
reason to return any payment made, the Lender may reverse any credit given in
respect of such item.

<PAGE>

Collateral other than as permitted under Section 7.4 of the Credit Agreement
and, in the case of any such permitted sale or exchange, the Security Interests
created hereby in such item (but not in any Proceeds arising from such sale or
exchange) shall cease immediately without any further action on the part of the
Lender, provided, however, that at the request of the Borrower, the Lender shall
execute and deliver such UCC-3 termination statements and other documents as may
be required to release such Security Interests in such item; or (ii) create,
incur or suffer to exist any Lien with respect to any Collateral, except for
Permitted Liens and the Security Interests.

      (i) The Borrower will keep each item of Equipment in good order and repair
(with allowance for ordinary wear and tear) and will not use the same in
violation of law or any policy of insurance thereon.

      (j) The Borrower shall, (i) not later than the date of the first advance
under the Credit Agreement, in the case of Equipment now owned constituting
goods in which a security interest is perfected by a notation on the certificate
of title or similar evidence of the ownership of such goods (other than
Equipment in which the Borrower has granted Permitted Liens), (a) having a value
in excess of $100,000 or (b) having a value in excess of $50,000, if the
aggregate of such items owned by the Borrower at any time is greater than
$100,000, and (ii) within 10 days of acquiring any other similar Equipment
(other than Equipment in which the Borrower has granted Permitted Liens) (x)
having a value in excess of $ 100,000 or (y) having a value in excess of
$50,000, if the aggregate of all such items owned by the Borrower at any time is
greater than $100,000, deliver to the Lender any and all certificates of title,
applications for title or similar evidence of ownership of such Equipment and
shall cause the Lender to be named as lienholder on any such certificate of
title or other evidence of ownership. The Borrower shall not permit any
additions to the Equipment to become a fixture to real estate other than real
estate in which the Lender has been granted a first priority Lien.

      (k) The Borrower will, promptly upon request, provide to the Lender all
information and evidence it may reasonably request concerning the Collateral to
the extent such information and evidence is in the Borrower's possession
(including without limitation, the names, addresses, face value, and date of
invoices for each debtor obligated on each Account) to enable the Lender to
enforce the provisions of this Agreement and, to the extent that any such
information or evidence is not in the possession of the Borrower, the Borrower
shall make such reasonable efforts as may be required to obtain such information
or evidence.

SECTION 5. General Authority

      The Borrower hereby irrevocably appoints the Lender its true and lawful
attorney, with full power of substitution, in the name of the Borrower, the
Lender, or otherwise, for the sole use and benefit of the Lender, but at the
Borrower's expense, to the extent permitted by law to exercise, at any time and
from time to time while an Event of Default has occurred and is continuing, all
or any of the following powers with respect to all or any of the Collateral:

            or security that may come into the Lender's possession,

            action or proceeding with respect thereto,

                  (d) to sell, transfer, assign or otherwise deal in or with the

                  (e) to extend the time of payment of any or all thereof and to
            make any allowance and other adjustments with reference thereto.

SECTION 6. Remedies upon Event of Default

      (a) If any Event of Default has occurred and is continuing, the Lender may
exercise all rights of a secured party under the UCC (whether or not in effect
in the jurisdiction where such rights are exercised) and, in addition, the
Lender may, without being required to give any notice, except as herein provided
or as may be required by law, sell the Collateral or any part thereof at public
or private sale, for cash, upon credit or for future delivery, and at such price
or prices as the Lender may deem satisfactory. The Lender may be the purchaser
of any or all of the Collateral so sold at any public sale (or, if the
Collateral is of a type customarily sold in a recognized market or is of a type
which is the subject of widely distributed standard price quotations, at any
private sale) and thereafter hold the same, absolutely, free from any right or
claim of whatsoever kind. The Lender shall give the Company not less than ten
days' prior written notice of the time and place of any sale or other intended
disposition of any of the Collateral, except any Collateral which is perishable
or threatens to decline speedily in value or is of a type customarily sold on a
recognized market. The Company agrees that such notice constitutes "reasonable
notification" within the meaning of Section 9-504(3) of the UCC. The Company
will execute and deliver such documents and take such other action as the Lender
deems necessary or advisable in order that any such sale may be made in
compliance with law. The Borrower will execute and deliver such documents and
take such other action as the Lender deems necessary or advisable in order that
any such sale may be made in compliance with law. Upon any such sale the Lender
shall have the right to deliver, assign and transfer to the purchaser thereof
the Collateral so sold. Each purchaser at any such sale shall hold the
Collateral so sold to it absolutely, free from any claim or right of whatsoever
kind, including any equity or right of redemption of the Borrower, and the
Borrower, to the extent permitted by law, hereby specifically waives all rights
of redemption, stay or appraisal which it has or may have under any law now
existing or hereafter adopted. The notice (if any) of such sale required by
Section 5 shall (A) in case of a public sale, state the time and place fixed for
such sale, and (B) in the case of a private sale, state the day after which such
sale may be consummated. Any such public sale shall be held at such time or
times within ordinary business hours and at such place or places as the Lender
may fix in the notice of such sale. At any such sale the Collateral may be sold
in one lot as an entirety or in separate parcels, as the Lender may determine.
The Lender shall not be obligated to make any such sale pursuant to any such
notice. The Lender may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for the sale, and such sale may be made at any


                                        9

<PAGE>

time or place to which the same may be so adjourned. In case of any sale of all
or any part of the Collateral on credit or for future delivery, the Collateral
so sold may be retained by the Lender until the selling price is paid by the
purchaser thereof, but the Lender shall not incur any liability in case of the
failure of such purchaser to take up and pay for the Collateral so sold and, in
case of any such failure, such Collateral may again be sold upon like notice.
The Lender, instead of exercising the power of sale herein conferred upon it,
may proceed by a suit or suits at law or in equity to foreclose the Security
Interests and sell the Collateral, or any portion thereof, under a judgment or
decree of a court or courts of competent jurisdiction.

      (b) For the purpose of enforcing any and all rights and remedies under
this Agrement the Lender may (i) require the Borrower to, and the Borrower
agrees that it will, at its expense and upon the request of the Lender,
forthwith assemble all or any part of the Collateral as directed by the Lender
and make it available at a place designated by the Lender which is, in its
opinion, reasonably convenient to the Lender, whether at the premises of the
Borrower or otherwise, (ii) to the extent permitted by applicable law, enter,
with or without process of law and without breach of the peace, any premises
where any of the Collateral is or may be located, and without charge or
liability to it or any Lender, seize and remove such Collateral from such
premises, (iii) have access to and use the Borrower's books and records relating
to the Collateral and (iv) prior to the disposition of the Collateral, store or
transfer it without charge in or by means of any storage or transportation
facility owned or leased by the Borrower, process, repair or recondition it or
otherwise prepare it for disposition in any manner and to the extent the Lender
deems appropriate to preserve and enhance its value and, in connection with such
preparation and disposition, use, as a licensee (or if no decline in the value
of the Collateral would result, otherwise) without charge any trademark, trade
name, copyright, patent or technical process used by the Borrower.

SECTION 7. Limitation on Duty of Lender in Respect of Collateral

      Beyond the safe custody thereof in accordance with applicable law, the
Lender shall have no duty as to any Collateral in its possession or control or
in the possession or control of any agent or bailee or any income thereon or as
to the preservation of rights against prior parties or any other rights
pertaining thereto. The Lender shall be deemed to have exercised reasonable care
in the custody and preservation of the Collateral in its possession if the
Collateral is accorded treatment substantially equal to that which it accords
its own property of like nature, arid shall not be liable or responsible for any
loss or damage to any of the Collateral, or for any diminution in the value
thereof, by reason of the act or omission of any warehouseman, carrier,
forwarding agency, consignee or other agent or bailee selected by the Lender in
good faith and in the absence of gross negligence.

SECTION 8. Application of Proceeds

      Upon the occurrence and during the continuance of an Event of Default, the
proceeds of any sale of, or other realization upon, all or any part of the
Collateral shall be applied by the Lender in the following order of priorities:

            first, to payment of the expenses of such sale or other realization,
      including reasonable compensation to the Lender and its agents and counsel
      in connection


                                       10

<PAGE>

      therewith, and all expenses, liabilities and advances incurred or made by
      the Lender in connection therewith, and any other unreimbursed expenses
      for which the Lender is to be reimbursed pursuant to the Credit Agreement
      or Section 9 hereof and unpaid fees owing to the Lender under the Credit
      Agreement;

            second, to the payment of accrued but unpaid interest on the Secured
      Obligations;

            third, to the payment of unpaid principal of the Secured
      Obligations;

            fourth, to the payment of all other Secured Obligations, until all
      Secured Obligations shall have been paid in full; and

            finally, to payment to the Borrowers or their respective successors
      or assigns, or as a court of competent jurisdiction may direct, of any
      surplus then remaining from such proceeds.

The Lender may make distributions hereunder in cash or in kind or in any
combination thereof.

SECTION 9. Expenses

      In the event that the Borrower fails to comply with the provisions of the
Credit Agreement or this Agreement, such that the value of any Collateral or the
validity, perfection, rank or value of any Security Interest is thereby
diminished or potentially diminished or put at risk, the Lender may effect such
compliance on behalf of the Borrower, and the Borrower shall reimburse the
Lender for the costs thereof within two Business Days of demand therefor. All
insurance expenses and all reasonable expenses of protecting, storing,
warehousing, appraising, insuring, handling, maintaining, and shipping the
Collateral, any and all excise, property, sales, and use taxes imposed by any
state, federal, or local authority on any of the Collateral, or in respect of
the sale or other disposition thereof, shall be borne and paid by the Borrower;
and if the Borrower fails to promptly pay any portion thereof when due, the
Lender may, at its option, but shall not be required to, pay the same and
charge the Borrower's account therefor, and the Borrower agrees to reimburse the
Lender therefor on demand. All sums so paid or incurred by the Lender for any of
the foregoing and any and all other sums for which the Borrower may become
liable hereunder and all reasonable costs and expenses (including attorneys'
fees, legal expenses and court costs) reasonably incurred by the Lender in
enforcing or protecting the Security Interests or any of their rights or
remedies under this Agreement, shall, together with interest thereon until paid
at the rate applicable to advances made under the Credit Agreement, be
additional Secured Obligations hereunder.

SECTION 10. Termination of Security Interests

      Upon the payment in full of all Secured Obligations and termination of the
Commitments, the Security Interests shall terminate and all rights to the
Collateral shall revert to the Borrower, and this Security Agreement shall
terminate and no longer be of any force and effect. After the termination of the
Security Interests pursuant to the preceding sentence and at the request of the
Borrower, the Lender shall take such action and execute and deliver to the
Borrower such UCC-3 termination statements and such other instruments as may be
required to release the Security Interests and return to the Borrower any
Collateral in its possession. If, after


                                       11

<PAGE>

the Security Interests are terminated, payment, or any part thereof, of any of
the Secured Obligations is rescinded or must otherwise be restored or returned
by the Lender upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Borrower or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or any substantial part of its property, or otherwise, the Security
Interests and all rights of the Lender to the Collateral shall be reinstated,
all as though such payments had not been made.

SECTION 11. Notices

      All notices, approvals, requests, demands and other communications
hereunder shall be given in accordance with the Credit Agreement.

SECTION 12. Waivers, Non-Exclusive Remedies

      No failure on the part of the Lender to exercise, and no delay in
exercising and no course of dealing with respect to, any right under the Credit
Agreement or this Agreement shall operate as a waiver thereof; nor shall any
single or partial exercise by the Lender of any right under the Credit Agreement
or this Agreement preclude any other or further exercise thereof or the exercise
of any other right. The rights in this Agreement and the Credit Agreement are
cumulative and are not exclusive of any other remedies provided by law.

SECTION 13. Successors and Assigns

      This Agreement is for the benefit of, and be enforceable by, the Lender,
and its successors and assigns, and in the event of an assignment of all or any
of the Secured Obligations, the rights, hereunder, to the extent applicable to
the indebtedness so assigned, may be transferred with such indebtedness. This
Agreement shall be binding on the Borrower and their respective successors and
assigns.

SECTION 14. Changes in Writings

      Neither this Agreement nor any provision hereof may be changed, waived,
discharged or terminated orally, but only in writing signed by the Borrower and
the Lender.

shall remain in full force and effect in such jurisdiction and shall be
liberally construed in favor of the Lender in order to carry out the intentions
of the parties hereto as nearly as may be possible; and (ii) the invalidity or

DOCUMENTS AND TO MAKE THE LOAN.

      SECTION 19. Revised Article 9 of the Uniform Commercial Code. The parties
acknowledge and agree to the following provisions of this Agreement in
anticipation of the possible application, in one or more jurisdictions, to the
transactions contemplated hereby of the revised Article 9 of the UCC in the form
or substantially in the form approved by the American Law Institute and the
National Conference of Commissioners on Uniform State Law contained in the 1999
official text of Revised Article 9 ("Revised Article 9").

      In applying the law of any jurisdiction in which Revised Article 9 is in
effect, the Collateral shall be and included all assets of the Borrower, whether
or not within the scope of Revised Article 9 with the exception of the Excluded
Property. The collateral shall include, without limitation, the following
categories of assets (as defined in Revised Article 9) belonging to the Borrower
or in which the Borrower has any rights: goods (including inventory, equipment
and any accessions thereto), instruments (including promissory notes),
documents, accounts, chattel paper (whether tangible or electronic), deposit
accounts, letter-of-credit rights (whether or not the letter of credit is
evidenced by writing), commercial tort claims, securities and all other
investment property, general intangibles (including payment intangibles and
software), supporting obligations and any and all proceeds thereof, wherever
located, whether now owned and hereafter acquired. If the Borrower shall at any
time, whether or not Revised Article 9 is in effect in any particular
jurisdiction, acquire a commercial tort claim, as defined in Revised Article 9,
the Borrower shall immediately notify the Lender in a writing signed by the
Borrower of the brief details thereof and grant to the Lender in such writing a
security interest therein and in the proceeds thereof, all upon the terms of
this Agreement, with such writing to be in form and substance satisfactory to
the Lender.

      The Lender may at any time and from time to time file financing
statements, continuation statements and amendments thereto that describe the
Collateral as all assets of the Borrower or words of similar effect and which
contain any other information required by Part 5 of Revised Article 9 for the
sufficiency or filing office acceptance of any financing statement, continuation
statement or amendment, including whether the Borrower is an organization, the
type of organization and any organization identification number issued to the
Borrower. The Borrower agrees to furnish any such information to the Lender
promptly upon request. Any such financing statements, continuation statements or
amendments may be signed by the Lender on behalf of the Borrower an may be filed
at any time in any jurisdiction whether or not Revised Article 9 is then in
effect in that jurisdiction.

      The Borrower shall at all times and from time to time, whether or not
Revised Article 9 is in effect in any particular jurisdiction, take such steps
as the Lender any reasonably request for the Lender (a) to obtain an
acknowledgment, in form and substance satisfactory to the Lender, of any bailee
having possession of any of the Collateral the bailee holds such Collateral for
the Lender, (b) to obtain "control" of any investment property, deposit
accounts, letter-of-credit rights or electronic chattel paper (as such terms are
defined in Revised Article 9 with corresponding provision in Section 9-104, 9-
105, 9-106 and 9-107 of Revised Article 9 relating to what constitutes "control"
for such items of Collateral), with any agreements establishing control to be in
form and substance satisfactory to the Lender, and (c) otherwise to insure the
continued perfection and priority of the Lender's security interest in any of
the Collateral and of the preservation of its rights therein, whether in
anticipation and following the effectiveness of Revised Article 9 in any
jurisdiction.


                                       13

<PAGE>

Nothing contained in this Section shall be construed to narrow the scope of the
Lender's security interest in any of the Collateral or the perfection or
priority thereof or to impair or otherwise limit any of the rights, powers,
privileges or remedies of the Lender hereunder except (and then only to the
extent) mandated by Revised Article 9 to the extent then applicable.
