     contrary within thirty (30) days after Borrower's receipt of any such 
     statement which Borrower deems to be incorrect.

COLLATERAL. To secure payment of the Line of Credit and performance of all 
other Loans, obligations and duties owed by Borrower to Lender, Borrower (and

     statement. Borrower will reimburse Lender for all expenses for the 
     perfection, termination, and the continuation of the perfection of

     notify Lender of any change in Borrower's name including any change to 
     the assumed business names of Borrower. Borrower also promptly will notify

     any other entity.

     keep correct and accurate records of the Collateral, all of which

REPRESENTATIONS AND WARRANTIES. Borrower represents and warrants to Lender,

     existing, and in good standing under the laws of the state of 
     Borrower's incorporation and is validly existing and in good standing

     most recent financial statement supplied to Lender. Borrower has no 
     material contingent obligations except as disclosed in such financial 
     statements.

     LEGAL EFFECT. This Agreement constitutes, and any instrument or 
     agreement required hereunder to be given by Borrower when delivered

     that: (a) During the period of Borrower's ownership of the properties, 
     there has been no use, generation, manufacture, storage, treatment,

     substance by any person on, under, about or from any of the properties. 
     (b) Borrower has no knowledge of, or reason to believe that there has

     litigation or claims of any kind by any person relating to such 
     matters. (c) Neither Borrower nor any tenant, contractor, agent or

     federal, state, and local laws, regulations, and ordinances, including

     above. Borrower authorizes Lender and its agents to enter upon the 
     properties to make such inspections and tests as Lender may deem

     of the Agreement. Any inspections or tests made by Lender shall be at 
     Borrower's expense and for Lender's purposes only and shall not be 
     construed to create any responsibility or liability on the part of 
     Lender to Borrower or to any other person. The representations and 
     warranties contained herein are based on Borrower's due diligence in 
     investigating the properties for hazardous waste and hazardous 
     substances. Borrower hereby (a) releases and waives any future claims 
     against Lender for indemnity or contribution in the event Borrower 
     becomes liable for cleanup or other costs under such laws, and (b) 
     agrees to indemnity and hold harmless Lender against any and all 
     claims, losses, liabilities, damages, penalties, and expenses which 
     Lender may directly or indirectly sustain or suffer resulting from a 
     breach of this section of the Agreement or as a consequence of any use, 
     generation, manufacture, storage, disposal, release or threatened

EVENTS OF DEFAULT. Each of the following shall constitute an Event of

    DEFAULT ON INDEBTEDNESS. Failure of Borrower to make any payment when due 
    on the Loans.

    OTHER DEFAULTS. Failure of Borrower or any Grantor to comply with or to
    perform when due any other term, obligation, covenant or condition contained
    in this Agreement or in any of the Related Documents, or failure of Borrower
    to comply with or to perform any other term, obligation, covenant or
    condition contained in any other agreement between Lender and Borrower.

    DEFAULT IN FAVOR OF THIRD PARTIES. Should Borrower or any Grantor default 
    under any loan, extension of credit, security agreement, purchase or sales 
    agreement, or any other agreement, in favor of any other creditor or person
    that may materially affect any of Borrower's property or Borrower's or any 
    Grantor's ability to repay the Loans or perform their respective obligations
    under this Agreement or any of the Related Documents.

    FALSE STATEMENTS. Any warranty, representation or statement made or 
    furnished to Lender by or on behalf of Borrower or any Grantor under this 
    Agreement or the Related Documents is false or misleading in any material 
    respect at the time made or furnished, or becomes false or misleading at any
    time thereafter.

    DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related 
    Documents ceases to be in full force and effect (including failure of any 
    Security Agreement to create a valid and perfected Security Interest) at any
    time and for any reason.

    INSOLVENCY. The dissolution or termination of Borrower's existence as a 
    going business, the insolvency of Borrower, the appointment of a receiver 
    for any part of Borrower's property, any assignment for the benefit of 
    creditors, any type of creditor workout, or the commencement of any 
    proceeding under any bankruptcy or insolvency laws by or against Borrower.

    CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or 
    forfeiture proceedings, whether by judicial proceeding, self-help, 
    repossession or any other method, by any creditor of Borrower, any creditor
    of any Grantor against any collateral securing the indebtedness, or by any 
    governmental agency. This includes a garnishment, attachment, or levy on or
    of any of Borrower's deposit accounts with Lender. However, this Event of 
    Default shall not apply if there is a good faith dispute by Borrower or 
    Grantor, as the case may be, as to the validity or reasonableness of the 
    claim which is the basis of the creditor or forfeiture proceeding, and if 
    Borrower or Grantor gives Lender written notice of the creditor or 
    forfeiture proceeding and furnishes reserves or a surety bond for the 
    creditor or forfeiture proceeding satisfactory to Lender.

    EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with 
    respect to any Guarantor of any of the indebtedness or any Guarantor dies 
    or becomes incompetent, or revokes or disputes the validity of, or liability
    under, any Guaranty of the Indebtedness. Lender, at its option, may, but 
    shall not be required to, permit the Guarantor's estate to assume 
    unconditionally the obligations arising under the guaranty in a manner 
    satisfactory to Lender, and, in doing so, cure the Event of Default.

    CHANGE IN OWNERSHIP. Any change in ownership of twenty-five percent (25%) 
    or more of the common stock of Borrower.

    ADVERSE CHANGE. A material adverse change occurs in Borrower's financial 
    condition, or Lender believes the prospect of payment or performance of the
    Indebtedness is impaired.

    RIGHT TO CURE. If any default, other than a Default on Indebtedness, is 
   curable and if Borrower or Grantor, as the case may be, has not been given a
   notice of a similar default within the preceding twelve (12) months, it may 
   be cured (and no Event of Default will have occurred) if Borrower or Grantor,
   as the case may be, after receiving written notice from Lender demanding cure
   of such default: (a) cures the default within fifteen (15) days; or (b) if 
   the cure requires more than fifteen (15) days, immediately initiates steps 
   which Lender deems in Lender's sole discretion to be sufficient to cure the 
   default and thereafter continues and completes all reasonable and necessary 
   steps sufficient to produce compliance as soon as reasonably practical.

EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, except 
where otherwise provided in this Agreement or the Related Documents, all 
commitments and obligations of Lender under this Agreement or the Related 
Documents or any other agreement immediately will terminate (including any 
obligation to make Loan Advances or disbursements), and, at Lender's option, 
all indebtedness immediately will become due and payable, all without notice 
of any kind to Borrower, except that in the case of an Event of Default of 
the type described in the "Insolvency" subsection above, such acceleration 
shall be automatic and not optional. In addition, Lender shall have all the 
rights and remedies provided in the Related Documents or available at law, in 
equity, or otherwise. Except as may be prohibited by applicable law, all of 
Lender's rights and remedies shall be cumulative and may be exercised 
singularly or concurrently. Election by Lender to pursue any remedy shall not 
exclude pursuit of any other remedy, and an election to make expenditures or 
to take action to perform an obligation of Borrower or of any Grantor shall 
not affect Lender's right to declare a default and to exercise its rights and 
remedies.

the purpose of the notice is to change the party's address. To the extent 
permitted by applicable law, if there's more than one Borrower, notice to any 
Borrower will constitute notice to all Borrowers. For notice purposes, 
Borrowers will keep Lender informed at all times of Borrower's current 
address(es). 

SEVERABILITY. If a court of competent jurisdiction finds any provision of this 
Agreement to be invalid or unenforceable as to any person or circumstance such 
finding shall not render that provision invalid or unenforceable as to any other
persons or circumstances. If feasible any such offending provision shall be 
deemed to be modified to be within the limits of enforceability or validity 
however, if the offending provision cannot be so modified it shall be stricken 
and all other provisions of this Agreement in all other respects shall remain 
valid and enforceable.

SUBSIDIARIES AND AFFILIATES OF BORROWER. To the extent the context of any 
provisions of this Agreement makes it appropriate, including without 
limitation any representation, warranty or covenant, the word "Borrower" as 
used herein shall include all subsidiaries and affiliates of Borrower. 
Notwithstanding the foregoing however, under no circumstances shall this 
Agreement be construed to require Lender to make any Loan or other financial 
accommodation to any subsidiary or affiliate of Borrower.

SUCCESSORS AND ASSIGNS. All covenants and agreements contained by or on 
behalf of Borrower shall bind its successors and assigns and shall inure to 
the benefit of Lender, its successors and assigns. Borrower shall not, 
however, have the right to assign its rights under this Agreement or any 
interest therein, without the prior written consent of Lender.

SURVIVAL. All warranties, representations and covenants made by Borrower in 
this Agreement or in any certificate or other instrument delivered by Borrower 
to Lender under this Agreement shall be considered to have been relied upon 
by Lender and will survive the making of the Loan and delivery to Lender of the 
Related Documents, regardless of any investigation made by Lender or on Lender's
behalf.

TIME IS OF THE ESSENCE. Time is of the essence in the performance of this 
Agreement.

WAIVER. Lender shall not be deemed to have waived any rights under this 
Agreement unless such waiver is given in writing and signed by Lender. No 
delay or omission on the part of Lender in exercising any right shall 
operate as a waiver of such right or any other right. A waiver by Lender of a 
provision of this Agreement shall not prejudice or constitute a waiver of 
Lender's right otherwise to demand strict compliance with that provision or any 
other provision of this Agreement. No prior waiver by Lender, nor any course of 
dealing between Lender and Borrower or between Lender and any Grantor shall 
constitute a waiver of any of Lender's rights or of any obligations of Borrower 
or of any Grantor as to any future transactions. Whenever the consent of Lender 
is required under this Agreement, the granting of such consent by Lender in 
any instance shall not constitute continuing consent in subsequent instances 
where such consent is required, and in all cases such consent may be granted 
or withheld on the sole discretion of Lender.

BORROWER ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS LOAN AGREEMENT,

THE AMOUNT IF $5,000,000.00.

DESCRIPTION OF COLLATERAL.
UCC FILING RECORDED APRIL 3, 1997 AS INSTRUMENT NUMBER 9710060309
COMMERCIAL SECURITY AGREEMENT DATED MARCH 27,1997.

DESCRIPTION OF CHANGE IN TERMS.  THE MATURITY DATE IS HEREBY CHANGED TO JUNE 
30,1998 FROM A PREVIOUS MATURITY DATE OF APRIL 30, 1998.  THE NOTE AMOUNT IS 
HEREBY INCREASED TO $10,000,000.00 FROM A PREVIOUS AMOUNT OF $5,000,000.00. 
BORROWER HEREBY ACKNOWLEDGES THAT THE COMMERCIAL SECURITY AGREEMENT DATED 
MARCH 27, 1997 AS WELL AS THE COMMERCIAL SECURITY AGREEMENT DATED JUNE 26, 
1997 REMAINS IN FULL FORCE AND EFFECT.  BORROWER AGREES TO THE REPAYMENT 
TERMS OUTLINED BELOW.  ALL OTHER TERMS AND CONDITIONS REMAIN THE SAME.

PROMISE TO PAY.  NATIONAL TELEPHONE & COMMUNICATIONS, INC. ("Borrower") 
promises to pay FIRST BANK & TRUST ("Lender"), or order, in lawful money of 
the United States of America, the principal amount of Ten Million & 00/100 
Dollars ($10,000,000.00) or so much as may be outstanding, together with 
interest on the unpaid outstanding principal balance of each advance.  
Interest shall be calculated from the date of each advance until repayment of 
each advance.

PAYMENT.  Borrower will pay this loan on demand, or if no demand interest is 
made, in one payment of all outstanding principal plus all accrued unpaid 
interest on June 30, 1998.  In addition, Borrower will pay regular monthly 
payments of accrued unpaid interest beginning June 27, 1997 and all 
subsequent interest payments are due on the same day of each month after 
that.  Interest on this Agreement is computed on a 365/360 simple interest 
basis; that is, by applying the ratio of the annual interest rate over a year 
of 360 days, multiplied by the outstanding principal balance multiplied by 
the actual number of days the principal balance is outstanding.  Borrower 
will pay Lender at Lender's address shown above or at such other place as 
Lender may designate in writing.  Unless otherwise agreed or required by 
applicable law, payments will be applied first to accrued unpaid interest, 
then to principal, and any remaining amount to any unpaid collection costs 
and late charges.

VARIABLE INTEREST RATE.  The interest rate on this Agreement is subject to 
change from time to time based on changes in an independent index which is 
the Prime rate as published in the Wall Street Journal.  When a range of 
rates has been published, the higher of the rates will be used (the "Index"). 
The Index is not necessarily the lowest rate charged by Lender on its loans. 
If the Index becomes unavailable during the term of this loan, Lender may 
designate a substitute Index after notice to Borrower.  Lender will tell 
Borrower the current index rate upon Borrower's request.  Borrower 
understands that Lender may make loans based on other rates as well.  The 
interest rate change will not occur more often than each quarter.  The Index 
currently is 8.500% per annum.  The interest rate to be applied to the unpaid
principal balance of this Agreement will be at a rate of 1.000 percentage 
point over the Index, resulting in an initial rate of 9.500% per annum.  
NOTICE: Under no circumstances will the interest rate on this Agreement be 
more than the maximum rate allowed by applicable law.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance 
charges are earned fully as of the date of the loan and will not be subject 
to refund upon early payment (whether voluntary or as a result of default), 
except as otherwise required by law.  Except for the foregoing, Borrower may 
pay without penalty all or a portion of the amount owed earlier than it is 
due.  Early payments will not, unless agreed to by Lender in writing, 
relieve Borrower of Borrower's obligation to continue to make payments of 
accrued unpaid interest.  Rather, they will reduce the principal balance due.

LATE CHARGE.  If a payment is 10 days or more late, Borrower will be charged 
5.000% of the unpaid portion of the regularly scheduled payment or $1.00, 
whichever is greater.

DEFAULT.  Borrower will be in default if any of the following happens:  (a) 
Borrower fails to make any payment when due.  (b) Borrower breaks any promise 
Borrower has made to Lender, or Borrower fails to comply with or to perform 
when due any other term, obligation, covenant, or condition contained in this 
Agreement or any agreement related to this Agreement, or in any other 
agreement or loan Borrower has with Lender.  (c) Borrower defaults under any 
loan, extension of credit, security agreement, purchase or sales agreement, 
or any other agreement, in favor of any other creditor or person that may 
materially affect any of Borrower's property or Borrower's ability to repay 
this Note or perform Borrower's obligations under this Note or any of the 
Related Documents.  (d) Any representation or statement made or furnished to 
Lender by Borrower or on Borrower's behalf is false or misleading in any 
material respect either now or at the time made or furnished. (e) Borrower 
becomes insolvent, a receiver is appointed for any part of Borrower's 
property, Borrower makes an assignment for the benefit of creditors, or any 
proceeding is commenced either by Borrower or against Borrower under any 
bankruptcy or insolvency laws.  (f) Any creditor tries to take any of 
Borrower's property on or in which Lender has a lien or security interest.  
This includes a garnishment of any of Borrower's accounts with Lender.  (g) 
Any guarantor dies or any of the other events described in this default 
section occurs with respect to any guarantor of this Agreement. (h) A 
material adverse change occurs in Borrower's financial condition, or Lender 
believes the prospect of payment or performance of the Indebtedness is 
impaired.

If any default, other than a default in payment, is curable and if Borrower 
has not been given a notice of a breach of the same provision of this 
Agreement within the preceding twelve (12) months, it may be cured (and no 
event of default will have occurred) if Borrower, after receiving written 
notice from Lender demanding cure of such default:  (a) cures the default 
within fifteen (15) days; or (b) if the cure requires more than fifteen (15) 
days immediately initiates steps which Lender deems in Lender's sole 
discretion to be sufficient to cure the default and thereafter continues and 
completes all reasonable and necessary steps sufficient to produce compliance 
as soon as reasonably practical.

LENDER'S RIGHTS.  Upon default, Lender may declare the entire unpaid 
principal balance on this Agreement and all accrued unpaid interest 
immediately due, without notice, and then Borrower will pay that amount.  
Upon Borrower's failure to pay all amounts declared due pursuant to this 
section, including failure to pay upon final maturity, Lender, at its option, 
may also, if permitted under applicable law, increase the variable interest 
rate in this Agreement to 6.000 percentage points over the Index.  Lender may 
hire or pay someone else to help collect this Agreement if Borrower does not 
pay.  Borrower also will pay Lender that amount.  This includes, subject to 
any limits under applicable law, Lender's attorneys' fees and Lender's legal 
expenses whether or not there is a lawsuit, including attorneys' fees and 
legal expenses for bankruptcy proceedings (including efforts to modify or 
vacate any automatic stay or injunction), appeals, and any anticipated 
post-judgement collection services. Borrower also will pay any court costs in 
addition to all other sums provided by law. This Agreement has been delivered 
to Lender and accepted by Lender in the State of California. If there is a 
lawsuit, Borrower agrees upon Lender's request to submit to the jurisdiction 
of the courts of Orange County, the State of California. Lender and Borrower 
hereby waive the right to any jury trial in any action, proceeding, or 
counterclaim brought by either Lender or Borrower against the other. (Initial 
Here  /s/ VCS) This Agreement shall be governed by and construed              
      -------
in accordance with the laws of the State of California.

DISHONORED ITEM FEE. Borrower will pay a fee to Lender of $15.00 if Borrower 
makes a payment on Borrower's loan and the check or preauthorized charge with 
which Borrower pays is later dishonored.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances 
under this Agreement may be requested orally by Borrower or by an authorized 
person. All oral requests shall be confirmed in writing on the day of the 
request. All communications, instructions, or directions by telephone or 
otherwise to Lender are to be directed to Lender's office shown above. The 
following party or parties are authorized to request advances under the line 
of credit until Lender receives from Borrower at Lender's address shown above 
written notice of revocation of their authority. JAMES R. QUANDT, PRESIDENT; 
VICTOR C. STREUFERT, CHIEF FINANCIAL OFFICER; and JERRY DECICCIO, CONTROLLER. 
Borrower agrees to be liable for all sums either: (a) advanced in accordance 
with the instructions of an authorized person or (b) credited to any of 
Borrower's accounts with Lender. The unpaid principal balance owing on this 
Agreement at any time may be evidenced by endorsements on this Agreement or 
by Lender's internal records, including daily computer print-outs. Lender will 
have no obligation to advance funds under this Agreement if: (a) Borrower or 
any guarantor is in default under the terms of this Agreement or any agreement 
that Borrower or any guarantor has with Lender, including any agreement made in 
connection with the signing of this Agreement, (b) Borrower or any guarantor 
ceases doing business or is insolvent, (c) any guarantor seeks, claims or 
otherwise attempts to limit, modify or revoke such guarantor's guarantee of 
this Agreement or any other loan with Lender; or (d) Borrower has applied 
funds provided pursuant to this Agreement for purposes other than those 
authorized by Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms 
of the original obligation or obligations, including all agreements evidenced 
or securing the obligation(s), remain unchanged and in full force and effect. 
Consent by Lender to this Agreement does not waive Lender's right to strict 
performance of the obligation(s) as changed, nor obligate Lender to make any 
future change in terms. Nothing in this Agreement will constitute a 
satisfaction of the obligation(s). It is the intention of Lender to retain as 
liable parties all makers and endorsers of the original obligations including 
accommodation parties, unless a party is expressly released by Lender in 
writing. Any maker or endorser, including accommodation makers will not be 
released by virtue of this Agreement. If any person who signed the original 
obligation does not sign this Agreement below, then all persons signing below 
acknowledge that this Agreement is given conditionally, based on the 
representation to Lender that the non-signing party consents to the changes 
and provisions of this Agreement or otherwise will not be released by it. The 
waiver applies not only to any initial extension, modification or release, 
but also to all such subsequent actions.

INTEREST RATE PROVISION 
THE INTEREST RATE WILL BE ADJUSTED ACCORDING TO THE DEBT/TNW RATIO: 

> 3.0 = WALL STREET JOURNAL PRIME PLUS 1.50% 
2.5 - 3.0 = WALL STREET JOURNAL PRIME PLUS 1.25% 
2.0 - 2.5 = WALL STREET JOURNAL PRIME PLUS 1.00%
< 2.0 = WALL STREET JOURNAL PRIME PLUS .75% 
(/s/ VCF  INITIAL HERE).

NON-USE FEE PROVISION. BORROWER AGREES TO A NON-USE FEE OF .2% PAID QUARTERLY.
(/s/ VCF  INITIAL HERE).
 ---------

MISCELLANEOUS PROVISIONS. This Agreement is payable on demand. The inclusion 
of specific default provisions or rights of Lender shall not preclude 
Lender's right to declare payment of this Agreement on its demand. Lender may 
delay or forgo enforcing any of its rights or remedies under this Agreement 
without losing them. Borrower and any other person who signs, guarantees or 
endorses this Agreement, to the extent allowed by law, waive any applicable 
statute of limitations, presentment, demand for payment, protest and notice 
of dishonor. Upon any change in the terms of this Agreement, and unless 
otherwise expressly stated in writing, no party who signs this Agreement, 
whether as maker, guarantor, accomodation maker or endorser, shall be 
released from liability. All such parties agree that Lender may renew or 
extend (repeatedly and for any length of time, this loan, or release any 
party or guarantor or collateral; or impair, fail to realize, upon or perfect 
Lender's security interest in the collateral, and take any other action 
deemed necessary by Lender without the consent of or notice to anyone. All 
such parties also agree that Lender may modify this loan without the consent 
of or notice to anyone other than the party with whom the modification is 
made.

PRIOR TO SIGNING THIS AGREEMENT, BORROWER READ AND UNDERSTOOD ALL THE 
PROVISIONS OF THIS AGREEMENT, INCLUDING THE VARIABLE INTEREST RATE PROVISIONS. 
BORROWER AGREES TO THE TERMS OF THE AGREEMENT AND ACKNOWLEDGES RECEIPT OF A

     the records concerning the Collateral) at Grantor's address shown above, 
     or at such other locations as are acceptable to the Lender. Except in the 
     ordinary course of its business, including the sales of inventory, 
     Grantor shall not remove the Collateral from its existing locations 
     without the  prior written consent of the Lender. To the extent that 
     the Collateral consists of vehicles, or other titled property, 
     Grantor shall not take  or permit any action which would require 
     application for certificates of title for the vehicles outside the 
     State of California, without the prior written consent of Lender.
     
     TRANSACTIONS INVOLVING COLLATERAL. Except for inventory sold or accounts 
     collected in the ordinary course of Grantor's business, Grantor shall

LOAN NO 973000139               (CONTINUED) 
- ----------------------------------------------------------------------------
- ----------------------------------------------------------------------------

     not sell, offer to sell, or otherwise transfer or dispose of the 
     Collateral. While Grantor is not in default under this Agreement, 
     Grantor may sell inventory, but only in the ordinary course of its 
     business and only to buyers who qualify as a buyer in the ordinary 
     course of business. A sale in the ordinary course of Grantor's business 
     does not include a transfer in partial or total satisfaction of a debt 
     or any bulk sale. Grantor shall not pledge, mortgage, encumber or 
     otherwise permit the Collateral to be subject to any lien, security 
     interest, encumbrance, or charge, other than the security interest 
     provided for in this Agreement, without the prior written consent of 
     Lender. This includes security interests even if junior in right to the 
     security interests granted under this Agreement. Unless waived by 
     Lender, all proceeds from any disposition of the Collateral (for 
     whatever reason) shall be held in trust for Lender and shall not be 
     commingled with any other funds; provided however, this requirement 
     shall not constitute consent by Lender to any sale or other 
     disposition. Upon receipt, Grantor shall immediately deliver any such 
     proceeds to Lender.

     TITLE.  Grantor represents and warrants to Lender that it holds good 
     and marketable title to the Collateral, free and clear of all liens and 
     encumbrances except for the lien of this Agreement. No financing 
     statement covering any of the Collateral is on file in any public 
     office other than those which reflect the security interest created by 
     this Agreement or to which Lender has specifically consented. Grantor 
     shall defend Lender's rights in the Collateral against the claims and 
     demands of all other persons.

     COLLATERAL SCHEDULES AND LOCATIONS. Insofar as the Collateral consists 
     of inventory, Grantor shall deliver to Lender, as often as Lender shall 
     require, such lists, descriptions, and designations of such Collateral 
     as Lender may require to identify the nature, extent, and location of 
     such Collateral. Such information shall be submitted for Grantor and 
     each of its subsidiaries or related companies.

     MAINTENANCE AND INSPECTION OF COLLATERAL. Grantor shall maintain all 
     tangible Collateral in good condition and repair. Grantor will not 
     commit or permit damage to or destruction of the Collateral or any part 
     of the Collateral. Lender and its designated representatives and agents 
     shall have the right at all reasonable times to examine, inspect, and 
     audit the Collateral wherever located. Grantor shall immediately 
     notify Lender of all cases involving the return, rejection, 
     repossession, loss or damage of or to any Collateral; of any request 
     for credit or adjustment or of any other dispute arising with respect 
     to the Collateral; and generally of all happenings and events affecting 
     the Collateral or the value or the amount of the Collateral.

     TAXES, ASSESSMENTS AND LIENS. Grantor will pay when due all taxes, 
     assessments and liens upon the Collateral, its use or operation, upon 
     this Agreement, upon any promissory note or notes evidencing the 
     Indebtedness, or upon any of the other Related Documents. Grantor may 
     withhold any such payment or may elect to contest any lien if Grantor 
     is in good faith conducting an appropriate proceeding to contest the 
     obligation to pay and so long as Lender's interest in the Collateral is 
     not jeopardized in Lender's sole opinion. If the Collateral is 
     subjected to a lien which is not discharged within fifteen (15) days, 
     Grantor shall deposit with Lender cash, a sufficient corporate surety 
     bond or other security satisfactory to Lender in an amount adequate to 
     provide for the discharge of the lien plus any interest, costs, 
     attorneys' fees or other charges that could accrue as a result of 
     foreclosure or sale of the Collateral. In any contest Grantor shall 
     defend itself and Lender and shall satisfy any final adverse judgment 
     before enforcement against the Collateral. Grantor shall name Lender as 
     an additional obligee under any surety bond furnished in the contest 
     proceedings.

     COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. Grantor shall comply 
     promptly, with all laws, ordinances, rules and regulations of all 
     governmental authorities, now or hereafter in effect, applicable to the 
     ownership, production, disposition, or use of the Collateral. Grantor 
     may contest in good faith any such law, ordinance or regulation and 
     withhold compliance during any proceeding, including appropriate 
     appeals, so long as Lender's interest in the Collateral, in Lender's 
     opinion, is not jeopardized.

     HAZARDOUS SUBSTANCES. Grantor represents and warrants that the 
     Collateral never has been, and never will be so long as this 
     Agreement remains a lien on the Collateral, used for the 
     generation, manufacture, storage, transportation, treatment, 
     disposal, release or threatened release of any hazardous waste 
     or substance, as those terms are defined in the Comprehensive 
     Environmental Response, Compensation, and Liability Act of 
     1980, as amended, 42 U.S.C. Section 9601, et seq. ("CERCLA"), 
     the Superfund Amendments and Reauthorization Act of 1986 
     Pub. L. No. 99-499 ("SARA"), the Hazardous Materials 
     Transportation Act, 49 U.S.C. Section 1801, et seq., the 
     Resource Conservation and Recovery Act, 42 U.S.C. Section 
     6901, et seq., Chapters 6.5 through 7.7 of Division 20 of the 
     California Health and Safety Code, Section 25100, et seq. or 
     other applicable state or Federal laws, rules, or regulations 
     adopted pursuant to any of the foregoing. The terms "hazardous 
     waste" and "hazardous substance" shall also include, without 
     limitation, petroleum and petroleum by-products or any 
     fraction thereof and asbestos. The representations and 
     warranties contained herein are based on Grantor's due 
     diligence in investigating the Collateral for hazardous wastes 
     and substances. Grantor hereby (a) releases and waives any 
     future claims against Lender for indemnity or contribution in 
     the event Grantor becomes liable for cleanup or other costs 
     under any such laws, and (b) agrees to indemnify and hold 
     harmless Lender against any and all claims and losses 
     resulting from a breach of this provision of this Agreement. 
     This obligation to indemnify shall survive the payment of the 
     Indebtedness and the satisfaction of this Agreement.

     MAINTENANCE OF CASUALTY INSURANCE. Grantor shall procure and maintain 
     all risks, insurance, including without limitation fire, theft and 
     liability coverage together with such other insurance as Lender may 
     require with respect to the Collateral, in form, amounts, coverages and 
     basis reasonably acceptable to Lender and issued by a company or 
     companies reasonably acceptable to Lender. Grantor, upon request of 
     Lender, will deliver to Lender from time to time the policies or 
     certificates of insurance in form satisfactory to Lender, including 
     stipulations that coverages will not be cancelled or diminished without 
     at least ten (10) days' prior written notice to Lender and not including 
     any disclaimer of the insurer's liability for failure to give such a 
     notice. Each insurance policy also shall include an endorsement 
     providing that coverage in favor of Lender will not be impaired in any 
     way by any act, omission or default of Grantor or any other person. In 
     connection with all policies covering assets in which Lender 
     holds or is offered a security interest, Grantor will provide Lender 
     with such loss payable or other endorsements as Lender may require. If 
     Grantor at any time fails to obtain or maintain any insurance as required 
     under this Agreement, Lender may (but shall not be obligated to) obtain 
     such insurance as Lender deems appropriate, including if it so chooses 
     "single interest insurance," which will cover only Lender's interest in 
     the Collateral.

     APPLICATION OF INSURANCE PROCEEDS. Grantor shall promptly notify Lender 
     of any loss or damage to the Collateral. Lender may make proof of loss 
     if Grantor fails to do so within fifteen (15) days of the casualty. All 
     proceeds of any insurance on the Collateral, including accrued proceeds 
     thereon, shall be held by Lender as part of the Collateral. If Lender 
     consents to repair or replacement of the damaged or destroyed 
     Collateral, Lender shall, upon satisfactory proof of expenditure, pay 
     or reimburse Grantor from the proceeds for the reasonable cost of 
     repair or restoration. If Lender does not consent to repair or 
     replacement of the Collateral, Lender shall retain a sufficient amount 
     of the proceeds to pay all of the Indebtedness, and shall pay the 
     balance to Grantor. Any proceeds which have not been disbursed within 
     six (6) months after their receipt and which Grantor has not committed 
     to the repair or restoration of the Collateral shall be used to prepay 
     the Indebtedness.

     INSURANCE RESERVES. Lender may require Grantor to maintain with Lender 
     reserves for payment of insurance premiums, which reserves shall be 
     created by monthly payments from Grantor of a sum estimated by Lender 
     to be sufficient to produce, at least fifteen (15) days before the 
     premium due date, amounts at least equal to the insurance premiums to 
     be paid. If fifteen (15) days before payment is due, the reserve funds 
     are insufficient, Grantor shall upon demand pay any deficiency to 
     Lender. The reserve funds shall be held by Lender as a general deposit 
     and shall constitute a non-interest-bearing account which Lender may 
     satisfy by payment of the insurance premiums required to be paid by 
     Grantor as they become due. Lender does not hold the reserve funds in 
     trust for Grantor, and Lender is not the agent of Grantor for payment 
     of the insurance premiums required to be paid by Grantor. The 
     responsibility for the payment of premiums shall remain Grantor's sole 
     responsibility.

     INSURANCE REPORTS. Grantor, upon request of Lender, shall furnish to 
     Lender reports on each existing policy of insurance showing such 
     information as Lender may reasonably request including the following: 
     (a) the name of the insurer; (b) the risks insured; (c) the amount of 
     the policy; (d) the property insured; (e) the then current value on the 
     basis of which insurance has been obtained and the manner of 
     determining that value; and (f) the expiration date of the policy. In 
     addition, Grantor shall upon request by Lender (however not more often 
     than annually) have an independent appraiser satisfactory to Lender 
     determine, as applicable, the cash value or replacement cost of the 
     Collateral.

GRANTOR'S RIGHT TO POSSESSION. Until default, Grantor may have 
possession of the tangible personal property and beneficial use of all the 
Collateral and may use it in any lawful manner not inconsistent with this 
Agreement or the Related Documents, provided that Grantor's right to 
possession and beneficial use shall not apply to any Collateral where 
possession of the Collateral by Lender is required by law to perfect Lender's 
security interest in such Collateral. If Lender at any time has possession of 
any Collateral, whether before or after an Event of Default, Lender shall be 
deemed to have exercised reasonable care in the custody and preservation of 
the Collateral if Lender takes such action for that purpose as Grantor shall 
request or as Lender, in Lender's sole discretion, shall deem appropriate 
under the circumstances, but failure to honor any request by Grantor shall 
not of itself be deemed to be a failure to exercise reasonable care. Lender 
shall not be required to take any steps necessary to preserve any rights in 
the Collateral against prior parties, nor to protect, preserve or maintain 
any security interest given to secure the Indebtedness.

EXPENDITURES BY LENDER. If not discharged or paid when due, Lender may (but 
shall not be obligated to) discharge or pay any amounts required to be 
discharged or paid by Grantor under this Agreement, including without 
limitation all taxes, liens, security interests, encumbrances, and other 
claims, at any time levied or placed on the Collateral. Lender also may (but 
shall not be obligated to) pay all costs for insuring, maintaining and 
preserving the Collateral. All such expenditures incurred or paid by Lender 
for such purposes will then bear interest at the rate charged under the Note 
from the date incurred or paid by Lender to the date of repayment by Grantor. 
All such expenses shall become a part of the Indebtedness and, at Lender's 
option, will (a) be payable on demand, (b) be added to the balance of the Note 
and be apportioned among and be payable with any installment payments to 
become due during either (i) the term of any applicable insurance policy or 
(ii) the remaining term of the Note, or (c) be treated as a balloon 
payment which will be due and payable at the Note's maturity. This Agreement 
also will secure payment of these amounts. Such right shall be in 
addition to all other rights and remedies to which Lender may be entitled 
upon the occurrence of an Event of Default.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default 
under this Agreement:


6-26-1997                COMMERCIAL SECURITY AGREEMENT                   Page 3
Loan No 973000139               (Continued) 
- ----------------------------------------------------------------------------
- ----------------------------------------------------------------------------

     OTHER DEFAULTS. Failure of Grantor to comply with or to perform any 
     other term, obligation, covenant or condition contained in this 
     Agreement or in any of the Related Documents or in any other agreement 
     between Lender and Grantor.

     DEFAULT IN FAVOR OF THIRD PARTIES. Should Borrower or any Grantor 
     default under any loan, extension of credit, security agreement, 
     purchase or sales agreement, or any other agreement, in favor of any 
     other creditor or person that may materially affect any of Borrower's 
     property or Borrower's or any Grantor's ability to repay the Loans or 
     perform their respective obligations under this Agreement or any of the 
     Related Documents.

     FALSE STATEMENTS. Any warranty, representation or statement made or 
     furnished to Lender by or on behalf of Grantor under this Agreement, 
     the Note or the Related Documents is false or misleading in any 
     material respect, either now or at the time made or furnished.

     DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related 
     Documents ceases to be in full force and effect (including failure of 
     any collateral documents to create a valid and perfected security 
     interest or lien) at any time and for any reason.

     INSOLVENCY. The dissolution or termination of Grantor's existence as a 
     going business, the insolvency of Grantor, the appointment of a receiver 
     for any part of Grantor's property, any assignment for the benefit of 
     creditors, any type of creditor workout, or the commencement of any 
     proceeding under any bankruptcy or insolvency laws against Grantor.

     CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or 
     forfeiture proceedings, whether by judicial proceeding, self-help, 
     repossession or any other method by any creditor of Grantor or by any 
     governmental agency against the Collateral or any other collateral 
     securing the indebtedness. This includes a garnishment of any of 
     Grantor's deposit accounts with Lender. However, this Event of Default 
     shall not apply if there is a good faith dispute by Grantor as to the 
     validity or reasonableness of the claim which is the basis of the 
     creditor or forfeiture proceeding and if Grantor gives Lender written 
     notice of the creditor or forfeiture proceeding and deposits with 
     Lender monies or a surety bond for the creditor or forfeiture 
     proceeding, in an amount determined by Lender, in its sole discretion, 
     as being an adequate reserve or bond for the dispute.

     EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with 
     respect to any Guarantor of any of the Indebtedness or such Guarantor 
     dies or becomes incompetent. Lender, at its option, may, but shall not 
     be required to, permit the Guarantor's estate to assume unconditionally 
     the obligations arising under the guaranty in a manner satisfactory to 
     Lender, and, in doing so, cure the Event of Default.

     ADVERSE CHANGE. A material adverse change occurs in Grantor's financial 
     condition, or Lender believes the prospect of payment or performance 
     of the indebtedness is impaired.

     RIGHT TO CURE.  If any default, other than a Default on Indebtedness, 
     is curable and if Grantor has not been given a prior notice of a 
     breach of the same provision of this Agreement, it may be cured (and 
     no Event of Default will have occurred) if Grantor, after Lender sends 
     written notice demanding cure of such default, (a) cures the default 
     within fifteen (15) days; or (b), if the cure requires more than 
     fifteen (15) days, immediately initiates steps which Lender deems in 
     Lender's sole discretion to be sufficient to cure the default and 
     thereafter continues and completes all reasonable and necessary steps 
     sufficient to produce compliance as soon as reasonably practical.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this 
Agreement, at any time thereafter, Lender shall have all the rights of a 
secured party under the California Uniform Commercial Code. In addition and 
without limitation, Lender may exercise any one or more of the following 
rights and remedies:

     ACCELERATE INDEBTEDNESS. Lender may declare the entire Indebtedness, 
     including any prepayment penalty which Grantor would be required to 
     pay, immediately due and payable, without notice.

     ASSEMBLE COLLATERAL. Lender may require Grantor to deliver to Lender 
     all or any portion of the Collateral and any and all certificates of title
     and other documents relating to the Collateral. Lender may require Grantor
     to assemble the Collateral and make it available to Lender at a place to
     be designated by Lender. Lender also shall have full power 
     to enter upon the property of Grantor to take possession of and remove 
     the Collateral. If the Collateral contains other goods not covered by 
     this Agreement at the time of repossession, Grantor agrees Lender 
     may take such other goods, provided that Lender makes reasonable 
     efforts to return them to Grantor after repossession.

     SELL THE COLLATERAL. Lender shall have full power to sell, lease, 
     transfer, or otherwise deal with the Collateral or proceeds thereof in 
     its own name or that of Grantor. Lender may sell the Collateral at 
     public auction or private sale. Unless the Collateral threatens to 
     decline speedily in value or is of a type customarily sold on a 
     recognized market, Lender will give Grantor reasonable notice of the 
     time after which any private sale or any other intended disposition of 
     the Collateral is to be made.  The requirements of reasonable notice 
     shall be met if such notice is given at least ten (10) days, or such 
     lesser time as required by state law, before the time of the sale or 
     disposition. All expenses relating to the disposition of the 
     Collateral, including without limitation the expenses of retaking, 
     holding, insuring, preparing for sale and selling the Collateral, shall 
     become a part of the indebtedness secured by this Agreement and shall 
     be payable on demand, with interest at the Note rate from date of 
     expenditure until repaid.

     APPOINT RECEIVER. To the extent permitted by applicable law, Lender 
     shall have the following rights and remedies regarding the appointment 
     of a receiver: (a) Lender may have a receiver appointed as a matter of 
     right, (b) the receiver may be an employee of Lender and may serve 
     without bond, and (c) all fees of receiver and his or her attorney 
     shall become part of the Indebtedness secured by this Agreement and 
     shall be payable on demand, with interest at the Note rate from date of 
     expenditure until repaid.

     COLLECT REVENUES, APPLY ACCOUNTS. Lender, either through itself or 
     through a receiver, may collect the payments, rents, income, and 
     revenues from the Collateral. Lender may at any time in its discretion 
     transfer any Collateral into its own name or that of its nominee and 
     receive the payments, rents, income, and revenues therefrom and hold 
     the same as security for the Indebtedness or apply it to payment of the 
     Indebtedness in such order of preference as the Lender may determine. 
     Insofar as the Collateral consists of accounts, general intangibles, 
     insurance policies, instruments, chattel paper, choses in action, or 
     similar property, Lender may demand, collect, receipt for, settle, 
     compromise, adjust, sue for, foreclose, or realize on the Collateral as 
     Lender may determine, whether or not Indebtedness or Collateral is 
     then due. For these purposes, Lender may, on behalf of and in the name 
     of Grantor, receive, open and dispose of mail addressed to Grantor, 
     change any address to which mail and payments are to be sent, and 
     endorse notes, checks, drafts, money orders, documents of title, 
     instruments and items pertaining to payment, shipment or storage of any 
     Collateral.  To facilitate collection, Lender may notify account 
     debtors and obligors on any Collateral to make payments directly to 
     Lender.

     OBTAIN DEFICIENCY. If Lender chooses to sell any or all of the 
     Collateral, Lender may obtain a judgment against Grantor for any 
     deficiency remaining on the Indebtedness due to Lender after 
     application of all amounts received from the exercise of the rights 
     provided in this Agreement. Grantor shall be liable for a deficiency 
     even if the transaction described in this subsection is a sale of 
     accounts or chattel paper.

     OTHER RIGHTS AND REMEDIES. Lender shall have all the rights and 
     remedies of a secured creditor under the provisions of the Uniform 
     Commercial Code, as may be amended from time to time. In addition, 
     Lender shall have and may exercise any or all other rights and remedies 
     it may have available at law, in equity, or otherwise.

     CUMULATIVE REMEDIES. All of Lender's rights and remedies, whether 
     evidenced by this Agreement or the Related Documents or by any other 
     writing, shall be cumulative and may be exercised singularly or 
     concurrently.  Election by Lender to pursue any remedy shall not 
     exclude pursuit of any other remedy, and an election to make 
     expenditures or to take action to perform an obligation of Grantor 
     under this Agreement, after Grantor's failure to perform, shall not 
     affect Lender's right to declare a default and to exercise its remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part 
of this Agreement:

     AMENDMENTS. This Agreement, together with any Related Documents, 
     constitutes the entire understanding and agreement of the parties as to 
     the matters set forth in this Agreement.  No alteration of or amendment 
     to this Agreement shall be effective unless given in writing and signed 
     by the party or parties sought to be charged or bound by the alteration 
     or amendment.

     APPLICABLE LAW.  This Agreement has been delivered to Lender and 
     accepted by Lender in the State of California. If there is a lawsuit, 
     Grantor agrees upon Lender's request to submit to the jurisdiction of the 
     courts of Orange County, the State of California. Lender and Grantor 
     hereby waive the right to any jury trial in any action, proceeding, or 
     counterclaim brought by either Lender or Grantor against the other.  
     (Initial Here /s/VCS) This Agreement shall be governed by and 
     construed in accordance with the laws of the State of California.

     ATTORNEYS' FEES; EXPENSES. Grantor agrees to pay upon demand all of 
     Lender's costs and expenses, including attorneys' fees and Lender's 
     legal expenses, incurred in connection with the enforcement of this 
     Agreement. Lender may pay someone else to help enforce this Agreement, 
     and Grantor shall pay the costs and expenses of such enforcement. Costs 
     and expenses include Lender's attorneys' fees and legal expenses 
     whether or not there is a lawsuit, including attorneys' fees and legal 
     expenses for bankruptcy proceedings (and including efforts to modify or 
     vacate any automatic stay or injunction), appeals, and any anticipated 
     post-judgment collection services.  Grantor also shall pay all court 
     costs and such additional fees as may be directed by the court.

     CAPTION HEADINGS. Caption headings in this Agreement are for 
     convenience purposes only and are not to be used to interpret or define 
     the provisions of this Agreement.

     MULTIPLE PARTIES; CORPORATE AUTHORITY. All obligations of Grantor under 
     this Agreement shall be joint and several, and all references to 
     Grantor shall mean each and every Grantor. This means that each of the 
     persons signing below is responsible for all obligations in this 
     Agreement.

     NOTICES. All notices required to be given under this Agreement shall be 
     given in writing may be sent by telefacsimile and shall be effective when

     actually delivered or when deposited with a nationally recognized 
     overnight courier or deposited in the United States mail, first class, 
     postage prepaid, addressed to the party to whom the notice is to be 
     given at the address shown above.  Any party may change its address for 
     notices under this Agreement by giving formal written notice to the 
     other parties specifying that the purpose of the notice is to change 
     the party's address. To the extent permitted by applicable law, if 
     there is more than one Grantor, notice to any Grantor will constitute 
     notice to all Grantors. For notice purposes, Grantor will keep Lender 
     informed at all times of Grantor's current address(es.)

     POWER OF ATTORNEY. Grantor hereby appoints Lender as its true and 
     lawful attorney-in-fact irrevocably, with full power of substitution to 
     do the following: (a) to demand, collect, receive, receipt for, sue and 
     recover all sums of money or other property which may now or hereafter 
     become due, owing or payable from the Collateral; (b) to execute, sign 
     and endorse any and all claims, instruments, receipts, checks, drafts 
     or warrants issued in payment for the Collateral; (c) to settle or 
     compromise any and all claims arising under the Collateral and, in the 
     place and stead of Grantor, to execute and deliver its release and 
     settlement for the claim, and (d) to file any claim or claims or to take 
     any action or institute or take part in any proceedings, either in its 
     own name or in the name of Grantor, or otherwise, which in the 
     discretion of Lender may seem to be necessary or advisable. This power 
     is given as security for the indebtedness and the authority hereby 
     conferred is and shall be irrevocable and shall remain in full force 
     and effect until renounced by Lender.

     PREFERENCE PAYMENTS. Any monies Lender pays because of an asserted 
     preference claim in Borrower's bankruptcy will become a part of the 
     indebtedness and at Lender's option, shall be payable by Borrower as 
     provided above in the "EXPENDITURES BY LENDER" paragraph.

     SEVERABILITY. If a court of competent jurisdiction finds any provision 
     of this Agreement to be invalid or unenforceable as to any person or 
     circumstance, such finding shall not render that provision invalid or 
     unenforceable as to any other persons or circumstances. If feasible any 
     such offending provision shall be deemed to be modified to be within 
     the limits of enforceability or validity; however, if the offending 
     provision cannot be so modified, it shall be stricken and all other 
     provisions of this Agreement in all other respects shall remain valid and 
     enforceable.

     SUCCESSOR INTERESTS. Subject to the limitations set forth above on 
     transfer of the Collateral, this Agreement shall be binding upon and 
     inure to the benefit of the parties, their successors and assigns.

     WAIVER. Lender shall not be deemed to have waived any rights under this 
     Agreement unless such waiver is given in writing and signed by Lender. 
     No delay or omission on the part of Lender in exercising any right 
     shall operate as a waiver of such right or any other right. A waiver by 
     Lender of a provision of this Agreement shall not prejudice or 
     constitute a waiver of Lender's right otherwise to demand strict 
     compliance with that provision or any other provision of this 
     Agreement. No prior waiver by Lender, nor any course of dealing between 
     Lender and Grantor shall constitute a waiver of any of Lender's rights 
     or of any of Grantor's obligations as to any future transactions. 
     Wherever the consent of Lender is required under this Agreement, the 
     granting of such consent by Lender in any instance shall not constitute 
     continuing consent to subsequent instances where such consent is 
     required and in all cases such consent may be granted or withheld in 
     the sole discretion of Lender.

     WAIVER OF CO-OBLIGOR'S RIGHTS. If more than one person is obligated for 
     the indebtedness, Borrower irrevocably waives, disclaims and 
     relinquishes all claims against such other person which Borrower has or 
     would otherwise have by virtue of payment of the indebtedness or any 
     part thereof, specifically including but not limited to all rights of 
     indemnity, contribution or exoneration.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS COMMERCIAL 
SECURITY AGREEMENT, AND GRANTOR AGREES TO ITS TERMS. THIS AGREEMENT IS DATED 
JUNE 26, 1997.

            coverage will not be cancelled or diminished without a minimum of 
            ten (10) days' prior written notice to Lender.

INSURANCE COMPANY. Grantor may obtain insurance from any insurance company 
Grantor may choose that is reasonably acceptable to Lender. Grantor 
understands that credit may not be denied solely because insurance was not

days from the date of this Agreement, evidence of the required insurance as 
provided above, with an effective date of June 26, 1997, or earlier. Grantor 
acknowledges and agrees that if Grantor fails to provide any required 
insurance or fails to continue such insurance in force, Lender may do so at 
Grantor's expense as provided in the applicable security document. The cost 
of any such insurance, at the option of the Lender, shall be payable on 
demand or shall be added to the indebtedness as provided in the security 
document. GRANTOR ACKNOWLEDGES THAT IF THE LENDER SO PURCHASES ANY SUCH 
INSURANCE, THE INSURANCE WILL PROVIDE LIMITED PROTECTION AGAINST PHYSICAL 
DAMAGE TO THE COLLATERAL, UP TO THE BALANCE OF THE LOAN; HOWEVER, GRANTOR'S 
EQUITY IN THE COLLATERAL MAY NOT BE INSURED. IN ADDITION, THE INSURANCE MAY 
NOT PROVIDE ANY PUBLIC LIABILITY OR PROPERTY DAMAGE INDEMNIFICATION AND MAY 
NOT MEET THE REQUIREMENTS OF ANY FINANCIAL RESPONSIBILITY LAWS.

AUTHORIZATION. For purposes of insurance coverage on the Collateral, Grantor 
authorizes Lender to provide to any person (including any insurance agent or 
company) all information Lender deems appropriate, whether regarding the 
Collateral, the loan or other financial accommodations, or both.

PROVIDE INSURANCE AND AGREES TO ITS TERMS. THIS AGREEMENT IS DATED JUNE 26,
