<PAGE>


GENERALLY -  "You" means the Secured Party identified  on page 1 of this
agreement.  "I", "me" and  "my" means each person who signs this security
agreement as Debtor and who agrees to give the property described in this
agreement as security for the Secured Debts.  All terms and duties under this
agreement are joint and individual. No modification of this security agreement
is effective unless made in writing and signed by you and me.  This security
agreement remains in  effect, even  if the note is paid and I owe no other debt
to you, until discharged in writing.  Time is of the essence in this agreement.

APPLICABLE LAW - I agree that this security agreement will be governed by the
law of  the state in which you are located.  If property described in this
agreement is located in another state, this agreement may also, in some
circumstances, be governed by  the law of the state in which  the property is
located.

  To the extent permitted by law, the terms of this agreement may vary
applicable law.  If any provision of applicable law may not be varied by
agreement, any provision  of this agreement that does not comply with the law
will not be effective.  If any provision of this agreement cannot be enforced
according to its terms, this fact will not affect the enforceability of the
remainder of this agreement.

OWNERSHIP AND DUTIES TOWARD  PROPERTY - I represent that I own all of the
property, or to the extend this is a purchase money security interest I will
acquire ownership of  the property with the proceeds of the loan.  I will defend
it against any other claim.  Your claim to the property is ahead of the claims
of any other creditor.  I agree to do whatever you require to protect your
security interest and to keep your claim in the property ahead of the claims of
other creditors.  I will not do anything to harm your position.

  I will keep books, records and accounts about the property and  my business
in general.  I will let you examine these records at any reasonable time.  I
will prepare any report or accounting you request, which deals with the
property.

  I will keep the property in my possession and will keep it in good repair and
use it only for the purpose(s) described  on page 1 of this agreement.  I will
not change this specified use without your express written permission.  I
represent that I am the original owner of the property and, if I am not, that I
have provided you with a list of prior owners of the property.

  I will keep the property at my address listed on page 1 of this agreement,
unless we agree I may keep it at another location.  If the property is to be
used in another state, I will give you a list of  those states.  I will not try
to sell the property unless it is inventory or I receive your written permission
to do so.  If I sell the property I will have the payment made payable to the
order of you and me.

  You may demand immediate payment of the debt(s) if the debtor is not a
natural person and without your prior written consent (1) a beneficial interest
in  the debtor is sold or transferred or (2) there is a change in either the
identity or number of members of a partnership or  (3) there is a change in
ownership of more than 25 percent of the voting stock of a corporation.

  I will pay all taxes and charges on the property as they become due.  You
have the right of reasonable access in order to inspect the 


                                       34
<PAGE>


property.  I will immediately inform you of any loss or damage to the property.

LIMITATIONS - This agreement will not secure a debt described in the section
entitled "Secured Debts" on page 1:

      1)  if  you fail to make any disclosure of the existence of this security
          interest required by law for such other debt;

      2)  if this security interest is in my principal dwelling and you fail to
          provide (to all persons entitled) any notice of right of rescission
          required by law for such other debt;

      3)  to the extent that this security interest is in "household goods" and
          the other debt to be secured is a "consumer" loan (as those terms are
          defined in applicable federal regulations governing unfair and
          deceptive credit practices);

      4)  if this security interest is in margin stock subject to the
          requirements of 12 C.F.R. Section 207 or 221 and you do not obtain a
          statement of purpose if required under these regulations with respect
          to that debt; or

      5)  if this security interest is unenforceable by law with respect to that
          debt.

PURCHASE MONEY SECURITY INTEREST - For the sole purpose of determining the
extent of a purchase money security interest arising under this security
agreement:  (a) payments on any non-purchase money loan also secured by this
agreement will not be deemed to apply to the purchase money loan, and (b)
payments on the purchase money loan will be deemed to apply first to the non-
purchase money portion  of the loan, if any, and  then to the purchase money 
obligations in the order in which the items of collateral were acquired or if
acquired at the same time, in the order selected by you.  No security interest
will be terminated by application of this formula.  "Purchase money loan" means
any loan the proceeds of  which, in  whole or in  part,  are used to acquire any
collateral securing the loan and all  extensions, renewals, consolidations and
refinancings of such loans. 

AUTHORITY OF SECURED PARTY TO MAKE ADVANCES AND  PERFORM FOR DEBTOR - I agree to
pay you on demand any sums you advanced on my behalf including, but not limited
to, expenses incurred in collecting, insuring, conserving, or  protecting the
property or in any inventories, audits, inspections or other examinations by you
in respect to the property.  If I fail to pay such sums, you may do so for me,
adding the amount paid to the other amounts secured by this agreement.  All such
sums will be due on demand and will bear interest at the highest rate provided
in any agreement, note or other instrument evidencing the Secured Debt(s) and
permitted by law at  the time of the advance.

   If I fail to perform any of my duties under this security agreement, or any 
mortgage, deed of trust, lien or other security interest, you may  without
notice to me perform the duties or cause them to be performed.  I understand
that this authorization includes, but is not limited to, permission to: (1)
prepare, file, and sign my name to any necessary reports or accountings; (2)
notify any account debtor of your interest in this property and tell the account
debtor to make the payments to you or someone else you name, rather than me; (3)
place on any chattel paper a note indicating your interest in the property; (4)
in my name, demand, collect, receive and give a receipt for compromise, 


                                       35
<PAGE>


settle, and handle any suits or  other proceedings involving the collateral; (5)
take any action you feel is necessary in order to realize on the collateral,
including performing any part of a contract or endorsing it in my name; and (6)
make an entry on my books and records showing the existence of the security
agreement.  Your right to perform for me shall not create  an obligation to
perform and your failure to perform will not preclude you from exercising any of
your rights under the law of this security agreement.

THESE SAME PARTIES WILL CONTROL THE  INSURANCE.

INSURANCE

WARRANTIES AND REPRESENTATIONS  - If this agreement includes accounts, I will
not settle any account for less than its full value without your written
permission.  I will collect all accounts until you tell  me otherwise. I will
keep the proceeds from all the accounts and any goods which are returned tome or
which I take back in trust for  you, I will not mix them with any other property
of mine.  I will deliver them to you at your request.  If you ask me to pay you
the full price on any returned items or items retaken by myself, I will do so.

   If this agreement covers inventory, I will not dispose of it except in my
ordinary course of business at the fair market value for the property, or at a
minimum price established between you and me.

   If this agreement covers farm products I will provide you, at your request,
a written list of the buyers, commission merchants or selling agents to  or 
through whom I may sell my farm products.  In addition  to those parties named
on this written list, I authorize you to notify at your sole discretion any
additional parties regarding your security interest in my farm products.  I
remain subject to all applicable  penalties for selling my farm products in
violation of my agreement with you and the Food Security Act.  In this paragraph
the terms farm products, buyers, commission merchants and selling agents have
the meanings given to them in the Federal Food Security Act of 1985. 

DEFAULT - I will be in default if any one or more of the following occur: (1) I
fail to make a payment on time or in the amount due; (2) I fail to keep the
property insured, if required; (3) I fail to pay, or keep any promise, on any
debt or agreement I have with you; (4) any other creditor of mine attempts to
collect any debt I owe him through court  proceedings; (5) I die, am declared
incompetent, make an assignment for  the benefit of creditors, or become
insolvent (either because my liabilities exceed my assets or I am unable to pay
my debts as they become due); (6) I make any written statement or provide any
financial information that is untrue or inaccurate at the time it was provided;
(7) I do or fail to do something which causes you to believe that you will have
difficulty collecting the amount I owe you; (8) I change my name or assume an
additional name without first notifying you before making such a change;  (9)
failure to plant, cultivate and harvest crops in due season;  (10) if any loan
proceeds are used for a purpose that will contribute to excessive erosion of
highly erodible land or to the conversion of wetlands to produce an agricultural
commodity, as further explained in 7 C.F.R. Part 1940, Subpart G, Exhibit M.


                                       36
<PAGE>


REMEDIES - If I am in default on this agreement, you have the following
remedies:

   1)  You may demand immediate payment of all  I  owe you under any obligation
       secured by this agreement.

   2)  You may set off any obligation I  have to you against any right I have to
       the payment of money from you.

   3)  You may demand more security or new parties obligated to pay any debt I
       owe you as a condition of giving up any other remedy.

   4)  You may make use of any remedy you have under state or federal law.

   5)  If I default by failing to pay taxes or other charges, you may pay them
       (but you are not required to do so). If you do, I will repay to you the
       amount you paid plus interest at the highest contract rate.

   6)  You may require me to gather the property and make it available to you in
       a reasonable fashion. 

   7)  You may repossess the property and sell it as provided by law.  You may
       repossess the property so long as the repossession does not involve a
       breach of the peace or an illegal entry onto my property.  You may sell
       the property as provided by law.  You may apply what you receive from the
       sale of the property to:  your expenses;  your reasonable attorney's fees
       and legal  expenses (where not prohibited by law); any debt I owe you. 
       If what you receive from the sale of the property does not satisfy the
       debts, you may take me to court to recover the difference (where
       permitted by law). 

       I agree that 10 days written notice sent to my address listed on  page 1
       by  first  class  mail  will be reasonable notice to me under the Uniform
       Commercial Code.

       If any items not otherwise subject to this agreement are contained in the
       property when you take possession, you may hold these items for me at my
       risk and you will not be liable for taking possession of them. 

   8)  In some cases, you may keep the property to satisfy the debt. You may
       enter upon and take possession of all or any part of my property, so long
       as you do not breach the peace or illegally enter onto the property,
       including lands, plants, buildings, machinery, and equipment as may be
       necessary to permit you to manufacture, produce, process, store or sell
       or complete the manufacture, production, processing, storing or sale of
       any of the property and to use and operate the property for the length of
       time you feel is necessary to protect your interest, all without payment
       or compensation to me.  

   By choosing any one or more of these remedies, you do not waive your right
to later  use any other remedy.  You do not waive a default if you choose not to
use any remedy, and, by electing not to use any remedy, you do not waive your
right to later consider the event a default and to immediately use any remedies
if it continues or occurs again.

FILING - A carbon, photographic or other reproduction of this security agreement
or the financing statement covering the property described in this agreement may
be used as a financing statement where allowed by law.  Where permitted by law,
you may file a financing statement which 


                                       37
<PAGE>


does not contain my signature, covering the property secured by this agreement.

CO-MAKERS - If  more than one of us has signed this agreement, we are all
obligated equally under the agreement.  You may sue any of one of us or  any of
us together if this agreement is violated.  You do not have to tell me if any
term  of the agreement has not been carried out. You may release any co-signer
and I will still be obligated under this agreement.  You may release any of the
security and I will still be obligated under this agreement.  Waiver by you of
any of your rights will not affect my duties under this agreement.  Extending
this agreement or new obligations under this agreement, will not affect my duty
under the agreement.
