Agreement, as the location of the Goods in question on the date hereof, except
if and to the extent that the Goods are either Inventory being shipped to or
from Grantor in the ordinary course of business or are mobile goods which are of
a type normally used in more than one jurisdiction and are in fact so used by
Grantor in the ordinary course of business. Grantor will not under any
circumstance suffer or permit any Goods in which Bank has been so granted a
security interest to be or become affixed to any real property in any manner
which would change its nature from that of personal property to real property or
to be or become a Fixture without Bank's prior written consent.

     5.2 Maintenance of Goods, Taxes and Preservation Costs. Grantor will
maintain in good condition all Goods in which Bank has been granted a security
interest pursuant to this Agreement, and will pay promptly all assessments,

                                        7

<PAGE>

thereof. If Grantor does not do so, then, and in each such case, Bank shall have
the right, at its option, to pay the same, and Grantor will, on Bank's demand,
reimburse Bank for all amounts Bank so pays. If Grantor does not reimburse Bank,
such amounts paid will become a part of the Subject Debt and will be secured
hereunder.

     5.3 Insurance. Grantor will at all times keep all Goods in which Bank has
been granted a security interest insured under so-called "cause of loss special
form" policies of insurance issued by such companies and in such amounts (but in
no case less than the greater of the full replacement value thereof or the
amount necessary to prevent the operation of any applicable coinsurance
provision) as shall be acceptable to Bank. Any determination by Bank regarding
the acceptability of the issuer or the amount of any insurance policy shall be
deemed to have been made without any representation or warranty of any kind,
Grantor hereby assuming the burden of ensuring that each such issuer and each
such amount is adequate for the protection of Grantor and all other Persons.
Grantor will cause each policy of insurance covering any Goods in which Bank has
been granted a security interest pursuant to this Agreement to (a) require the
insurer to give Bank written notice not less than thirty (30) days prior to any
cancellation, expiration, modification, or non-renewal of the policy, (b) have
attached thereto (i) a lender's loss payable endorsement in favor of Bank,
entitling Bank to collect any and all proceeds payable under the policy and
providing in effect that the rights and interests of Bank thereunder are
independent of, and shall not be diminished or impaired by, any action,
inaction, or breach of condition on the part of Grantor and (ii) a waiver of
subrogation endorsement, and (c) be otherwise in form and substance satisfactory
to Bank. Grantor will pay all premiums for the foregoing policies of insurance
as and when due and will cause the issuer of each such policy to deliver an
original counterpart thereof directly to Bank. Grantor hereby assigns to Bank
any returned or unearned premiums due upon cancellation of any such insurance
and directs insurer to pay to Bank all amounts so due. All or any portion of
amounts received by Bank in payment of insurance losses or returned or unearned
premiums may, at Bank's option, be applied to the Subject Debt (with such
allocation to the respective parts thereof and the respective due dates thereof
as Bank in its sole discretion may from time to time deem advisable) or to the
repair, replacement, or restoration of the Goods insured. Grantor hereby
irrevocably appoints Bank as Grantor's attorney-in-fact to adjust all insurance
losses, to sign all applications, receipts, releases, and other Records
necessary to collect any such loss and any returned or unearned premiums, to
execute proofs of loss, to make settlements, to indorse and collect any check or
other item payable to Grantor issued in connection therewith, and to apply the
same to payment of the Subject Debt as hereinbefore provided. If Grantor does
not maintain insurance pursuant to this subsection, then, and in each such case,
Bank shall have the right to obtain such insurance or obtain insurance covering
only Bank's interest, and, if Bank elects to do either, Grantor will, on Bank's
demand, reimburse Bank for all amounts Bank expends in doing so. If Grantor does
not reimburse Bank, such amounts paid will become part of the Subject Debt and
will be secured hereunder.

     5.4 Acquisition and Disposition of Inventory. Bank does not authorize, and
Grantor agrees not to:

                                        8

<PAGE>

          (a) sell, transfer, or otherwise dispose of any Inventory, except
that so long as no Default exists, Grantor shall have the right, in the ordinary
course of business but not otherwise, to process and sell Inventory for
customary prices, provided, that Grantor shall immediately deposit the Proceeds
of each such sale to the cash collateral account, if any then exists, pursuant
to subsection 6.5, or, if none then exists, to the credit of Grantor's general
checking account with Bank or any Deposit Account over which Bank has Control,
without Bank's prior written consent; or

          (b) permit any Goods in which Bank has been granted a security
interest pursuant to this Agreement to be evidenced by any warehouse receipt or
other document of title (other than any bill of lading or similar Document
covering Inventory that has been sold in accordance with this section) or by any
lease, license, conditional sales agreement, or other Chattel Paper of any kind.

shall apply with respect to all Accounts in which Bank has been granted a
security interest pursuant to this Agreement:

instrumentality, or political subdivision thereof or (b) does not take the form
of an Account or is evidenced in whole or in part by Chattel Paper or any
Instrument.

     6.2 Collection of Accounts by Grantor. Subject to the provisions of
subsection 6.3, Grantor will collect the Accounts in the ordinary course of
business for the benefit of both Bank and Grantor at no cost or expense to Bank.
Until any Default shall have occurred and thereafter unless and until Bank shall
have advised Grantor to the contrary, Grantor shall have the right in the
ordinary course of business, to grant such waivers and consents to, enter into
such compromises with, and otherwise deal with the Account Debtors in respect of
the Accounts as Grantor in good faith may from time to time deem advisable.

     6.3 Direct Payment to Bank or Lockbox. Bank shall have the right, (a) at
any time to enforce Grantor's rights against the Account Debtors and Obligors
including, without limitation, instructing Account Debtors, at Grantor's
expense, to thereafter make their payments in respect of the Accounts directly
to Bank and (b) in any event, by giving prior notice to Grantor, from time to
time to require Grantor to instruct the Account Debtors thereafter to mail their
payments to a post office lockbox which Bank shall maintain at Grantor's expense
and to which only Bank shall have access and control. Following Bank's exercise
of either such right, Grantor will not, without in each case first obtaining
Bank's consent, demand payment in respect of any Account, and if Grantor shall
at any time receive any payment in respect of any Account, Grantor will in each
case give Bank prompt notice thereof, hold the amount so received in trust for
the benefit of Bank, and promptly remit the same to Bank in the very form in
which received but with all necessary indorsements and assignments to facilitate
Bank's collection thereof.

     6.4 Authority of Account Debtors. Grantor irrevocably authorizes and
directs each Account Debtor to honor any demand by Bank that all payments in
respect of the Accounts thereafter be paid directly to Bank. In each such case
the Account Debtor may continue directing all such payments to Bank until the
Account Debtor shall have received written notice from Bank either that the
Subject Debt has been paid in full or that Bank no longer claims a security
interest in the Accounts. No Account Debtor shall have any responsibility to
inquire into Bank's right to make any such demand or to follow Bank's
disposition of any monies paid to Bank by the Account Debtor.

     6.5 Deposits. All payments in respect of the Accounts shall, at Bank's
option, be deposited either to a checking account maintained by Grantor with
Bank, a Deposit Account over which Bank has Control or to a cash collateral
account which shall bear no interest, over which Bank shall have sole dominion
and control, and from which only Bank may withdraw funds, whichever option Bank
shall from time to time elect by giving Grantor written notice thereof. Bank
shall have no responsibility to ascertain whether any such payment is the
correct amount owing. Each such deposit shall be subject to Bank's general rules
and regulations except to the extent, if any, inconsistent with this Agreement.

     6.6 Withdrawal and Application of Funds. Bank may from time to time
withdraw funds from the cash collateral account at will. Bank shall be under no
obligation to withdraw funds from the cash collateral account, except that upon
each request of Grantor, Bank shall, if no Default then exists, withdraw all
such funds that are then collected. All funds so withdrawn shall be applied to
the payment of the Subject Debt with such allocation to the respective parts
thereof and the respective due dates thereof as Bank in its sole discretion may
from time to time deem advisable (except that so long as no Default exists, Bank
shall not apply any such withdrawal to any Subject Debt that is not then due
without first obtaining Grantor's consent). If any funds so withdrawn and
applied are recovered from Bank by any trustee in bankruptcy or any other Person
or are discovered not to have been collected and collection thereof is denied to
Bank, Bank shall have the right to reverse any such application to the extent
the funds are recovered from or not collected by Bank. Bank in its discretion
may from time to time release to Grantor (or to Grantor's order) any or all of
the funds then held in the cash collateral account, but no such release or
releases shall commit Bank thereafter to make any further or other such
releases.

     6.7 Vouchers, Receipts, and Indorsements. Bank shall have full power and
authority to execute and deliver such vouchers and receipts in respect of the
Accounts, such indorsements of checks, and such other Records in respect of the
foregoing as Bank may from time to time deem advisable. In connection with the
foregoing, Bank shall have full power and authority to sign Grantor's signature
to all such vouchers, receipts, indorsements, and other Records whenever Bank
deems such action advisable.

     6.8 Verification of Accounts. Bank shall have the right, at any time and
from time to time, to arrange for verification of Accounts directly with Account
Debtors or by such other methods as Bank shall deem advisable.

                                       10

7. Maintenance and Defense of General Intangibles. Subject in each case to any
security interest in favor of Bank and Bank's rights in respect thereof, and
further subject to section 6 governing Accounts, Grantor will, until any Default
shall have occurred and thereafter unless and until Bank shall have advised
Grantor to the contrary, without expense to Bank, maintain, enforce, and
exercise Grantor's rights in all General Intangibles (except any which are of no
material value) and defend and protect those intangibles against dilution,
diminution in value, infringement, misappropriation, and unauthorized use.

8. Effects of Default. Bank shall at all times have all of the rights of a
secured party under the law of the jurisdiction in which Bank's banking office
is located and, in addition, if any Default shall occur or commence to exist,
then, and in each such case, the following provisions shall apply:

     8.1 Possession of Goods and Records. Bank shall have the right to take
possession of all Goods in which Bank has been granted a security interest
pursuant to this Agreement, or such part of those Goods as Bank may from time to
time deem advisable, and Grantor will, on each demand of Bank, assemble and make
available to Bank at such place or places as Bank may reasonably require such of
those Goods as Bank shall designate. Grantor will, on Bank's demand, deliver to
Bank all of Grantor's books and records in respect of the Collateral.

     8.2 Enforcement of Rights. Bank shall have the right in its sole discretion
to enforce payment of the Accounts by suit or otherwise, and to maintain and
enforce rights in respect of any General Intangibles and Accounts, but Bank
shall have no duty to institute any suit or to take any other action or, having
started any suit or the taking of any other action, to thereafter continue the
same. In each case Bank may proceed with counsel of Bank's choosing (at
Grantor's expense).

     8.3 Exercise of Rights. Bank shall have full power and right to exercise
any and all rights and remedies available at law (including, without limitation,
those available under the provisions of the UCC) or in equity to collect,
enforce, or satisfy any of the Subject Debt and exercise any and all rights in
respect of the Collateral as if Bank were the sole beneficial owner thereof and
may, without limitation, grant such waivers and consents to, and enter into such
compromises with, the Account Debtors and other Persons, release (regardless of
whether Bank receives any consideration therefor) any security for or any
Account Debtor or other Person liable on any Account, and grant the Account
Debtors and other Persons such other indulgences as Bank in good faith may from
time to time deem advisable. Grantor waives any rights it may have, if any, to
require Bank to pursue any other Obligor for any of the Subject Debt.

     8.4 Disposition. Bank shall have the right to sell or otherwise dispose of
the Collateral or any part thereof or any interest therein at any time or from
time to time. Bank shall have no obligation to clean-up or otherwise prepare the
Collateral for sale. Bank may comply with any applicable state or federal law
requirements in connection with a disposition of the Collateral and compliance
will not be considered adversely to affect the commercial reasonableness of any
sale of the Collateral. Bank may sell or otherwise dispose of the

                                       11

<PAGE>

Collateral without giving any warranties as to the Collateral and may
specifically disclaim any warranties of title or the like, any or all of which
will not be considered adversely to affect the commercial reasonableness of any
sale or other disposition of the Collateral. Bank shall give Grantor
commercially reasonable prior notice of either the date after which any intended
private sale is to be made or the time and place of any intended public sale,
except that Bank need give no such notice in the case of Collateral which Bank
in good faith determines to be declining speedily in value or which is
customarily sold on a recognized market. Grantor waives advertisement of any
such sale and (except only to the extent notice is specifically required by the
next preceding sentence or as may otherwise be required by the UCC) waives
notice of any kind in respect of such sale. At any public sale Bank may purchase
the Collateral or any part thereof free from any right of redemption, which
right Grantor hereby waives. After deducting for any and all fees, costs, and
expenses (including, without limitation, the fees and disbursements of legal
counsel) incurred in assembling, taking, repairing, storing, and selling or
otherwise disposing of the Collateral or any part thereof or any interest
therein, Bank shall have the right to apply the net proceeds of the sale to the
Subject Debt with such allocation to the respective parts thereof and the
respective due dates thereof as Bank in its sole discretion may from time to
time deem advisable, and Grantor shall be liable for any deficiency.

9. Additional Authorizations. Grantor hereby irrevocably constitutes and
appoints Bank, through its employees and agents, with full power of
substitution, as Grantor's true and lawful attorney-in-fact, with full
irrevocable power and authority in the place of Grantor and in the name of
Grantor or in Bank's own name, for the purpose of carrying out the terms of this
Agreement, to perform, at any time and from time to time, each agreement
contained in this Agreement that is on Grantor's part to be complied with, and
to take any and all actions and to execute and deliver any and all Records which
may be necessary or desirable to give Bank the full benefit of this Agreement,
in each case as Bank may from time to time deem advisable, Grantor hereby
agreeing that Bank shall owe no duty whatever to Grantor to perform any such
agreement, to take any such action, or to execute or deliver any such Record,
or, having done so any one or more times, to thereafter continue doing so.
Without limiting the generality of the foregoing, Grantor hereby irrevocably
authorizes Bank, at any time and from time to time, to (a) fill in any blank
space contained in this Agreement or any other Related Writing or Record, (b)
correct patent errors, to complete and correct the description of Collateral,
and to complete the date herein or therein, (c) file, and if necessary sign, on
Grantors' behalf and file, at Grantors" expense and without Grantor's signature,
such affidavits, assignments, financing statements, indorsements of specific
items of Collateral, mortgages, powers of attorney, security agreements, or
other Records as Bank may from time to time deem advisable for the better
evidencing, perfection, protection, or validation of, or realization of the
benefits of, the security interest granted pursuant to this Agreement, and (d)
to the extent Bank filed any such affidavits, assignments, financing statements,
indorsements of specific items of Collateral, mortgages, powers of attorney,
security agreements, or other Records prior to the date of this Agreement, such
affidavits, assignments, financing statements, indorsements of specific items of
Collateral, mortgages, powers of attorney, security agreements, or other Records
are hereby ratified by Grantor.

                                       12

10. Unconditional and Continuing Security Interest. Grantor's obligations under
this Agreement and the granting of a security interest to Bank pursuant to this
Agreement are unconditional and effective immediately, and (except for
obligations surviving indefinitely pursuant to section 16) those obligations and
the security interest so granted shall continue in full effect until the Subject
Debt shall have been paid in full and any Commitment is terminated and
thereafter until Bank shall have delivered to Grantor (or such other Person or
Persons whom Bank determines in good faith to be entitled to the same) all
Collateral (except any applied to the Subject Debt) in Bank's possession and
until each assignment, financing statement, or other Record describing the
Collateral and naming Bank (or its successors or assigns, if any) as assignee or
secured party, as the case may be, shall have been released or terminated of
record as to all of the Collateral therein described, regardless of the lapse of
time, regardless of the fact that there may be a time or times when no Subject
Debt is outstanding, regardless of any act, omission, or course of dealing
whatever on Bank's part, and regardless of any other event, condition, or thing.

11. Grantor's Assent to Extensions, Releases, and Settlements. With respect to
the Collateral, Grantor assents to any extension or postponement of the time of
payment thereof or any other indulgence in connection therewith, to any
exchange, release, replacement, or substitution of Collateral, to any addition
or release of any Account Debtor, to any acceptance of any partial payment
thereon and to any adjustment, compromise, or settlement in respect thereof, all
in such manner and at such time or times as Bank shall deem advisable. Grantor
hereby waives any right it may have to require Bank to pursue any other Obligor
for any of the Subject Debt.

12. Bank's Duties Limited. Grantor agrees that Bank shall have no duty to
collect or protect the Collateral or any income therefrom, nor to preserve
rights against prior parties, beyond the safe custody of any Collateral in
Bank's possession. Bank shall have no liability for its delivery of any property
to any Person or Persons whom Bank determines in good faith to be entitled to
the same.

13. No Setoff. Grantor hereby waives all now existing or hereafter arising
rights to recoup or offset any obligation of Grantor under or in connection with
this Agreement or any Related Writing against any claim or right of Grantor
against Bank.

14. Indemnity: Administration, Enforcement, and Termination; Interest. Grantor
will reimburse Bank, on Bank's demand from time to time, for any and all fees,
costs, and expenses (including, without limitation, the fees and disbursements
of legal counsel) incurred by Bank in administering this Agreement and in
enforcing, exercising, or protecting its rights under this Agreement or under
applicable law, or in attempting to do any of the foregoing. Grantor agrees that
if and when Bank's security interest shall have terminated in accordance with
the provisions of this Agreement, Grantor will, on Bank's demand from time to
time, reimburse Bank for any and all fees, costs, and expenses (including,
without limitation, the fees and disbursements of legal counsel) incurred by
Bank in releasing or terminating each assignment, financing statement, or other
Record signed or given pursuant to this Agreement or in notifying Account
Debtors of any such release or termination. If any amount owing under this
Agreement is not paid when due, then, and in each such case, Grantor shall pay,

                                       13

<PAGE>

on Bank's demand, interest on that amount from the due date thereof until paid
in full at a fluctuating rate equal to four percent (4%) per annum plus the
Prime Rate.

15. Waivers; Remedies; Application of Payments. Bank may from time to time in
its discretion grant waivers and consents in respect of this Agreement or any
other Related Writing or assent to amendments thereof, but no such waiver,
consent, or amendment shall be binding upon Bank unless set forth in a writing
(which writing shall be narrowly construed) signed by Bank. No course of dealing
in respect of, nor any omission or delay in the exercise of, any right, power,
or privilege by Bank shall operate as a waiver thereof, nor shall any single or
partial exercise thereof preclude any further or other exercise thereof or of
any other, as each such right, power, or privilege may be exercised either
independently or concurrently with others and as often and in such order as Bank
may deem expedient. Each right, power, or privilege specified or referred to in
this Agreement is in addition to, and not in limitation of any other rights,
powers, and privileges that Bank may otherwise have or acquire by operation of
law, by other contract, or otherwise. Bank shall be entitled to equitable
remedies with respect to each breach or anticipatory repudiation of any
provision of this Agreement, and Grantor hereby waives any defense that might be
asserted to bar any such equitable remedy. Bank shall have the right to apply
Proceeds and payments in respect of the Subject Debt with such allocation to the
respective parts thereof and the respective due dates thereof as Bank in its
sole discretion may from time to time deem advisable.

16. Other Provisions. The provisions of this Agreement shall bind Grantor and
Grantor's executors, heirs, representatives, successors, and assigns and all
Persons who become bound as a debtor or grantor to this Agreement and benefit
Bank and its successors and assigns, including each subsequent holder, if any,
of the Subject Debt or any part thereof. Except for Grantor and Bank and their
respective successors and assigns, there are no intended beneficiaries of this
Agreement, provided, that Bank shall have the right, in its discretion, to
designate, at any time and from time to time, one or more Account Debtors as
intended beneficiaries of subsection 6.4. If Grantor is more than one Person,
then, at Bank's discretion, those Persons, or any of them, may be deemed to be
jointly and severally liable for the payment and performance of Grantor's
obligations under this Agreement. The provisions of sections 11 through 19,
both inclusive, shall survive the payment in full of the Subject Debt and
termination of the security interest granted pursuant to this Agreement. The
several captions to different sections and subsections of this Agreement are
inserted for convenience only and shall be ignored in interpreting the
provisions thereof. Each reference to a section includes a reference to all
subsections thereof (i.e., those having the same character or characters to the
left of the decimal point), except where the context clearly does not so permit.
If any provision in this Agreement shall be or become illegal or unenforceable
in any case, then that provision shall be deemed modified in that case so as to
be legal and enforceable to the maximum extent permitted by law while most
nearly preserving its original intent, and in any case the illegality or
unenforceability of that provision shall affect neither that provision in any
other case nor any other provision. Interest for any given period shall accrue
on the first day thereof but not on the last day thereof (unless the last day is
the first day) and in each case shall be computed on the basis of a 360-day year
and the actual number of days in the period. In no event shall interest accrue
at a higher rate than the maximum rate, if any, permitted by law. Grantor hereby
authorizes Bank to share all

                                       14

<PAGE>

credit and financial information relating to Grantor with Bank's parent company,
with any subsidiary or Affiliate of Bank or of Bank's parent company, with any
actual or proposed participant in or assignee of all or any part of Bank's
interests or rights hereunder, or with any other Person reasonably deemed
necessary by Bank to the administration hereof. This Agreement shall be governed
by the law (excluding conflict of laws rules) of the jurisdiction in which
Bank's banking office is located.

17. Integration. This Agreement and, to the extent consistent with this
Agreement, the other Related Writings, set forth the entire agreement of Grantor
and Bank as to its subject matter, and may not be contradicted by evidence of
any agreement or statement unless made in a writing (which writing shall be
narrowly construed) signed by Bank contemporaneously with or after the execution
and delivery of this Agreement.

18. Notices and Other Communications. Each notice, demand, or other
communication, whether or not received, shall be deemed to have been given to
Grantor whenever Bank shall have mailed a writing to that effect by certified or
registered mail, or recognized overnight courier service to Grantor at Grantors
mailing address (or any other address of which Grantor shall have given Bank
notice after the execution and delivery of this Agreement). Each communication
to be given to Bank shall be in writing and shall be given to Bank at Bank's
banking office (or any other address of which Bank shall have given notice to
Grantor after the execution and delivery of this Agreement). Grantor hereby
assumes all risk arising out of or in connection with each communication given
or attempted by Grantor in contravention of this section. Bank shall be entitled
to rely on each communication believed in good faith by Bank to be genuine.

19. Jurisdiction and Venue; Waiver of Jury Trial. Any action, claim,
counterclaim, crossclaim, proceeding, or suit, whether at law or in equity,
whether sounding in tort, contract, or otherwise at any time arising under or in
connection with this Agreement or any other Related Writing, the administration,
enforcement, or negotiation of this Agreement or any other Related Writing, or
the performance of any obligation in respect of this Agreement or any other
Related Writing (each such action, claim, counterclaim, crossclaim, proceeding,
or suit, an "Action") may be brought in any federal or state court located in
the city in which Bank's banking office is located. Grantor hereby
unconditionally submits to the jurisdiction of any such court with respect to
each such Action and hereby waives any objection Grantor may now or hereafter
have to the venue of any such Action brought in any such court. GRANTOR HEREBY,
AND EACH HOLDER OF THE SUBJECT DEBT OR ANY PART THEREOF, KNOWINGLY AND
VOLUNTARILY WAIVES JURY TRIAL IN RESPECT OF ANY ACTION.

     IN WITNESS WHEREOF, Grantor, intending to be legally bound, has executed
this Security Agreement on the day and year first above written with the
intention that this Agreement shall constitute a sealed instrument.

                                    Grantor:
