THIS AGREEMENT SPECIFICALLY INCLUDES ALL OF THE ADDITIONAL 
PROVISIONS SET FORTH ON THE REVERSE SIDE HEREOF.  DEBTOR 
ACKNOWLEDGES RECEIPT OF A FULLY COMPLETED COPY OF THIS SECURITY 
AGREEMENT.

                                ADDITIONAL PROVISIONS

    1.   Representations and Agreements.  Debtor represents and 
agrees as follows:


                                         -2-



              a.   If a corporation or other business entity, 
Debtor is duly organized, existing and is qualified in good 
standing in all states in which it is doing business, and the 
execution, delivery and performance of this Security Agreement are 
within Debtor's powers, having been duly authorized, and are not 
in contravention of law or the terms of Debtor's charter, bylaws, 
if any, or any indenture, agreement, or undertaking to which 
Debtor is a party, or by which it is bound.  If an individual, 
Debtor is of legal age.  Debtor will not change his, her or its 
name, or identity unless written notice is given in advance to 
Secured Party.

              b.   Debtor shall maintain insurance upon the 
Collateral which is tangible property against all customarily 
insured risks for the full insurable value thereof (and furnish 
Secured Party with duplicate policies if Secured Party so 
requests), loss to be payable to Debtor and Secured Party as their 
respective interests may appear.  In the event of any loss or 
damage to any Collateral, Debtor will give Secured Party written 
notice thereof forthwith, promptly file proof of loss with the 
appropriate insurer and take all other steps necessary or 
appropriate to collect such insurance.  If Secured Party so 
elects, Secured Party shall have full authority to collect all 
such insurance and to apply any amount collected to amounts owed 
hereunder, whether or not matured.  Secured Party shall have no 
liability for any loss which may occur by reason of the omission 
or the lack of coverage of any such insurance.

              c.   Debtor shall at all times maintain Collateral 
which is tangible property in good condition and repair, defend at 
Debtor's expense all Collateral from all adverse claims and shall 
not use any of the Collateral for any illegal purpose.

              d.   Debtor shall (i) keep such books and records 
pertaining to the Collateral and to Debtor's business operations 
as shall be satisfactory to Secured Party; (ii) permit 
representatives of Secured Party at any time to inspect the 
Collateral and inspect and make abstracts from Debtor's books and 
records; and (iii) furnish to Secured Party such information and 
reports regarding the Collateral and Debtor's business operations 
and its financial status, as Secured Party may from time to time 
reasonably require.  Secured Party is hereby authorized to request 
confirmation of such information or additional information of any 
kind whatsoever.

              e.   Debtor shall give such notice in writing 
(including but not limited to notice of assignment or notice to 
pay Secured Party directly) as Secured Party may require at any 
time to any or all account debtors, with respect to accounts which 
are Collateral, and, if Secured Party shall so request, deliver to 
Secured Party copies of any and all such notices.


                                         -3-



              f.   Debtor shall promptly transmit to Secured 
Party all information that it may have or receive with respect to 
Collateral or with respect to any account debtor which might in 
any way affect the value of the Collateral or Secured Party's 
rights or remedies with respect hereto.

              g.   Unless in default under this Agreement, 
Debtor may sell inventory in the ordinary course of business and 
consume any raw materials or supplies, the use and consumption of 
which are necessary to carry on Debtor's business.  Debtor shall 
not otherwise consume, assign or transfer any Collateral without 
prior written consent of Secured Party.  The provision of this 
Agreement granting a security interest in proceeds shall not be 
construed to mean that Secured Party consents to any sale or 
disposition of any Collateral.

              h.   Debtor shall pay when due all taxes, 
assessments, and any other governmental levy which is, or may be, 
levied against any Collateral, and shall otherwise maintain the 
Collateral free of all liens, charges, and encumbrances (except 
liens set forth herein and the security interest created hereby).

              i.   Debtor shall not store any Collateral with 
any warehouseman without Secured Party's consent.

              j.   Debtor shall promptly, unless Secured Party 
shall waive such requirement in writing, deliver to Secured Party 
all certificates of title, if any, (or any other documents 
evidencing title) to all Collateral with such proper notations, 
assignments, or endorsements as may be necessary or appropriate to 
create, preserve or protect Secured Party's security interest in 
the Collateral.

              k.   Debtor shall, at its cost and expense, 
execute, deliver, file or record, in any such manner or form as 
the Secured Party may require, any assignment, financing statement 
or other paper that may be necessary or desirable, or that Secured 
Party may request, in order to create, preserve or perfect any 
security interest granted hereby or to enable Secured Party to 
exercise and enforce its rights hereunder or under any Collateral. 
Secured Party is further granted the power, coupled with an 
interest, to sign on behalf of Debtor as attorney-in-fact and to 
file one or more financing statements under the Uniform Commercial 
Code naming Debtor as debtor and Secured Party as secured party 
and describing the Collateral herein specified.

    2.   Expenses.  Debtor upon demand shall pay to Secured 
Party forthwith the amounts of all expenses, including reasonable 
attorney's fees and legal expenses, incurred by Secured Party, in 
seeking to collect any sums secured hereunder or to enforce any 
rights in the Collateral.  Such amounts shall be secured hereby, 


                                         -4-



and if not paid on demand shall bear interest at the highest rate 
payable on any of the Obligations.


    3.   Collection Authority on Accounts.  Debtor hereby 
irrevocably appoints Secured Party its true and lawful attorney, 
with full power of substitution, in Secured Party's name, Debtor's 
name or otherwise, for Secured Party's sole use and benefit, but 
at Debtor's cost and expense, to exercise, if Secured Party shall 
elect after an event of default has occurred (whether or not 
Secured Party then elects to exercise any other of its rights 
arising upon default) all or any of the following powers with 
respect to all or any Accounts which are Collateral:

              a.   To execute on Debtor's behalf assignments of 
any or all Accounts which are Collateral to Secured Party, and  to 
notify account debtors thereunder to make payments directly to 
Secured Party;

              b.   To demand, sue for, collect, receive, and 
give acquittance for any and all moneys due or to become due upon 
or by virtue thereof;

              c.   To receive, take, endorse, assign and deliver 
any and all checks, notes, drafts, documents and other negotiable 
and non-negotiable instruments and chattel paper taken or received 
by Secured Party in connection therewith;

              d.   To settle, compromise, compound, prosecute or 
defend any action or proceeding with respect thereto;

              e.   To sell, transfer, assign or otherwise deal 
in or with the same or the proceeds thereof or the relative goods, 
as fully and effectually as if Secured Party were the absolute 
owner thereof; and

              f.   To extend the time or payment of any or all 
thereof and to make any allowance and other adjustments with 
reference thereto.

Any funds collected pursuant to such powers shall be applied to 
the payment of the Obligations.  The exercise by Secured Party of, 
or failure to so exercise, any of the foregoing authority, shall 
in no manner affect Debtor's liability to Secured Party on any of 
the Obligations.  Secured Party shall be under no obligation or 
duty to exercise any of the powers hereby conferred upon it and it 
shall be without liability for any act or failure to act in 
connection with the collection of or the preservation of any 
rights under any such accounts.  Secured Party shall not be bound 
to take any steps necessary to preserve rights in any instrument 
or other chattel paper against prior parties.


                                         -5-



    4.   Set-Off.  In the event of default hereunder, Secured 
Party at its option at any time, and without notice to Debtor, may 
apply against the Obligations any property of Debtor held by 
Secured Party.  As additional security for payment of the 
Obligations, Debtor hereby grants to Secured Party a security 
interest in any funds or property of Debtor now or hereafter in 
possession of Secured Party and with respect hereto Secured Party 
will have all rights and remedies herein specified.

    5.   Waiver.  Debtor waives protest, notice of dishonor, and 
presentment of all commercial paper at any time held by Secured 
Party on which Debtor is in any way liable, notice of non-payment 
at maturity of any account or chattel paper, and notice of any 
action taken by Secured Party except where notice is expressly 
required by this Agreement or cannot by law be waived.

    6.   Default.  Debtor will be in default upon the occurrence 
of any of the following events: (a) failure to make payment when 
due and payable, of any of the Obligations; (b) failure of the 
performance of any obligation or covenant contained or referred to 
herein, after failing to cure same upon 15 days notice; (c) any 
warranty, representation or statement made or furnished to Secured 
Party by or on behalf of Debtor proves to have been false in any 
material respect when made or furnished; (d) any event which 
results in the acceleration of the maturity of the indebtedness of 
Debtor or any guarantor or co-maker of any of the Obligations to 
others under any indenture, agreement or undertaking; (e) loss, 
theft, damage, destruction or encumbrance to, or of, the 
Collateral or the making of any levy, seizure of attachment 
thereof or thereon; (f) death of, dissolution of, termination of 
existence of, insolvency of, business failure of, appointment of a 
receiver of any part of the property of, assignment for the 
benefit of creditors by, or the commencement of any proceeding 
under any bankruptcy or insolvency law by or against, Debtor or 
any guarantor or co-maker of any of the Obligations; (g) the 
occurrence or nonoccurrence of any event or events which causes 
the Secured Party, in good faith, to deem itself insecure for any 
reason whatsoever.

    In any such event Secured Party may at its option declare any 
or all of the Obligations to be due and payable and such sums 
shall then be due and payable immediately, without notice or 
demand.

    7.   Rights and Remedies on Default.  After the occurrence 
of any event of default, Secured Party may exercise at any time 
and from time to time any rights and remedies available to it 
under applicable law, including but not limited to the right to 
sell, lease or otherwise dispose of the collateral, and the right 
to take possession of the Collateral.  For that purpose, Secured 
Party may enter upon any premises on which the Collateral or any 
part thereof may be situated and remove it.  Secured Party may 
require Debtor to


                                         -6-



assemble the Collateral and make it available at a place to be designated by
Secured Party which is reasonable convenient to both parties.  If at the time of
repossession any of the Collateral contains other personal property not included
in the Collateral, Secured Party may take such personal property into 
custody and store it at the risk and expense of Debtor.  Debtor agrees to notify
Secured Party within forty-eight (48) hours after repossession of the Collateral
of any such other personal property claimed, and failure to do so will release
Secured Party and its representatives from any liability for loss or damage
thereto.  Any notice or of intended disposition of any of the Collateral 
required by law shall be deemed reasonable if such notice is given at least
seven (7) days before the time of such disposition.  Any proceeds of any
disposition by Secured Party of any of the Collateral may be applied by it to
the payment of expenses in connection with the Collateral, including but not
limited to repossession expenses and reasonable attorney fees and legal 
expenses, and any balance of such proceeds shall be then applied against the
Obligations and other amounts secured hereby in such order of application as
Secured Party may elect.

    8.   General Provisions.

              a.   Secured Party may, at its option, pay any 
tax, assessment, or other Governmental levy, or insurance premium 
or any other expense or charge relating to Collateral which is 
payable by Debtor and not timely paid by it, and further may pay 
any filing or recording fees.  Any amount or amounts so pay, with 
interest thereon at the highest rate payable on any of the 
Obligations from the date of payment until repaid shall be secured 
hereby and shall be payable upon demand.

              b.   Secured Party shall not be deemed to have 
waived any of its rights hereunder or under any other agreement, 
instrument, or paper signed by Debtor unless such waiver be in 
writing and signed by Secured Party.  No delay or omission on the 
part of Secured Party in exercising any right shall operate as a 
waiver of such right or any other right.  A waiver on any one 
occasion shall not be construed as a bar to, or waiver of, any 
right or remedy on any future occasion.

              c.   Any note, if mailed, shall be deemed 
reasonable and given when mailed postage prepaid, addressed to the 
Debtor at the address shown above, or at any other address of 
Debtor appearing on Secured Party's records.

              d.   Covenants, representations, warranties and 
agreements herein set forth shall be binding upon Debtor, its 
legal representatives, successors, and assigns.  This Agreement 
may be assigned by Secured Party and all rights and privileges of 
Secured 


                                         -7-




Party under this Agreement shall then inure to the benefit 
of its successors and assigns.

              e.   If any provision of this Agreement shall be 
for any reason held to be invalid or unenforceable, such 
invalidity or unenforceability shall not effect any other 
provisions hereof, but this Agreement shall be construed as if 
such invalid or unenforceable provision had never been contained 
herein.

              f.   If Debtor is a guarantor, endorser, co-maker, 
or an accommodation party with respect to the Obligations, Debtor 
hereby waives the benefit of any and all defenses and claims of 
damage which are dependant upon Debtor's character as a party 
other than the maker.  Each party to any of the Obligations hereby 
consents to and waives notice of (1) any and all extensions, 
whether or not for longer than the original period, granted as to 
the time of payment of any or all of the Obligations, and (2) any 
renewal of any or all of the Obligations.

              g.   This Agreement and all rights and duties 
hereunder, including but not limited to all matters of 
construction, validity, and performance shall be governed by the 
law of the State of Iowa and any suit hereon may be instituted in 
Des Moines, Polk County, Iowa.

              h.   Unless otherwise defined or the context 
otherwise requires, all terms used herein which are defined in the 
Iowa Uniform Commercial Code shall have the meanings therein 
stated.  The rights and remedies herein conferred upon Secured 
Party shall be in addition to, and not in substitution or in 
derogation of, rights and remedies conferred by the Iowa Uniform 
Commercial Code and other applicable law.

              i.   All words and phrases used herein shall be 
construe as in the singular or plural number, and as masculine, 
feminine or neuter gender, as the context may require.  Captions
