LINE OF CREDIT.  Lender  agrees to make  Advances to Borrower  from time to time

amount of such  Advances  outstanding  at any time does not  exceed  the Line of
Credit.  Within the foregoing limits,  Borrower may borrow,  partially or wholly
prepay, and reborrow under this Agreement as follows.

Conditions Precedent to Each Advance. Lender's obligation to make any Advance to
or for the account of Borrower  under this Agreement is subject to the following
conditions precedent, with all documents,  instruments,  opinions,  reports, and
other  items  required  under  this  Agreement  to  be  in  form  and  substance
satisfactory to Lender:

(a) Lender shall have  received  evidence  that this  Agreement  and all Related
Documents  have been duly  authorized,  executed,  and  delivered by Borrower to
Lender.

(b) Lender shall have received such opinions of counsel,  supplemental opinions,
and documents as Lender may request.

(c) The security  interests in the Collateral  shall have been duly  authorized,
created,  and perfected  with first lien priority and shall be in full force and
effect.

(d) All  guaranties  required  by Lender for the Line of Credit  shall have been
executed  by each  Guarantor,  delivered  to  Lender,  and be in full  force and
effect.

(e) Lender,  at its option and for its sole  benefit,  shall have  conducted  an
audit  of  Borrower's  books,  records,  and  operations,  and  Lender  shall be
satisfied as to their condition.

(f) Borrower shall have paid to Lender all fees,  costs, and expenses  specified
in this Agreement and the Related Documents as are then due and payable.

(g) There  shall not exist at the time of any  Advance a  condition  which would
constitute an Event of Default under this Agreement.


Making Loan Advances.  Advances under the Line of Credit may be requested orally
subject to the  limitations set forth below.  Lender may, but need not,  require
that  all  oral  requests  be  confirmed  in  writing.  Each  Advance  shall  be
conclusively  deemed to have been made at the  request of and for the benefit of
Borrower (a) when credited to any deposit  account of Borrower  maintained  with
Lender or (b) when advanced in accordance with the instructions of an authorized
person.  Lender, at its option,  may set a cutoff time, after which all requests
for Advances  will be treated as having been  requested  on the next  succeeding
Business Day.

Mandatory Loan Repayments.  If at any time the aggregate principal amount of the
outstanding  Advances  shall  exceed the  applicable  Line of Credit,  Borrower,
immediately  upon  written or oral  notice from  Lender,  shall pay to Lender an
amount equal to the difference between the outstanding  principal balance of the
Advances and the Line of Credit.  On the Expiration Date,  Borrower shall pay to
Lender  in full the  aggregate  unpaid  principal  amount of all  Advances  then
outstanding and all accrued unpaid interest,  together with all other applicable
fees, costs and charges, if any, not yet paid.

Loan  Account.  Lender shall  maintain on its books a record of account in which
Lender  shall make entries for each Advance and such other debits and credits as
shall be  appropriate  in  connection  with the credit  facility.  Lender  shall
provide  Borrower  with  periodic  statements  of  Borrower's   account,   which
statements  shall be  considered  to be  correct  and  conclusively  binding  on
Borrower unless Borrower notifies Lender to the contrary within thirty (30) days
after  Borrower's  receipt  of any such  statement  which  Borrower  deems to be
incorrect.

Out of Debt  Provision.  Borrower  shall  maintain a zero balance on the Line of
Credit for a period of at least thirty (30)  consecutive days during the term of
this loan.

Letter of Credit Sublimit.  Subject to the terms of this Agreement,  Lender will
issue standby letters of credit and commercial letters of credit (each a "Letter
of Credit") on behalf of  Borrower.  At no time,  however,  shall the total face
amount of all Letters of Credit  outstanding,  less any partial draws paid under
the Letters of Credit exceed the sum of $100,000.00. For purposes of calculating
the amount of  Advances  available  under the Line of  Credit,  100% of the face
amount of the  outstanding  Letters of Credit shall be deemed Advances under the
Line of Credit and therefore subtracted from the amount available under the Line
of Credit.

(a) Upon Lender's  request,  Borrower promptly shall pay to Lender issuance fees
and such other fees, commissions,  costs, and any out-of-pocket expenses charged
or incurred by Lender with respect to any Letter of Credit.


(b) The  commitment by Lender to issue Letters of Credit shall,  unless  earlier
terminated  in  accordance  with  the  terms  of this  Agreement,  automatically
terminate on the Expiration Date and no standby Letter of Credit shall expire on
a date which is sixty (60) days after the Expiration Date.

(c) Each Letter of Credit shall be in form and substance  satisfactory to Lender
and in favor of beneficiaries  satisfactory to Lender,  provided that Lender may
refuse to issue a Letter of Credit due to the nature of the  transaction  or its
terms or in connection with any transaction where Lender, due to the beneficiary
or the nationality or residence of the  beneficiary,  would be prohibited by any
applicable law,  regulation,  or order from issuing such Letter of Credit. Under
no circumstances, however, will a commercial Letter of Credit and standby Letter
of Credit  exceed one hundred  twenty (120) days and three  hundred  sixty (360)
days from the issue date, respectively.

(d) Prior to the  issuance of each Letter of Credit,  and in all events prior to
any daily cutoff time Lender may have established for purposes thereof, Borrower
shall  deliver  to Lender a duly  executed  form of  Lender's  standard  form of
application for issuance of letter of credit with proper insertions.

Lender's  Rights  Upon  Default.  Upon the  occurrence  of any Event of Default,
Lender may,  at its sole and  absolute  discretion  and in addition to any other
remedies available to it under this Agreement or otherwise,  require Borrower to
pay  immediately  to  Lender,   for  application   against  drawings  under  any
outstanding  Letters of Credit,  the  outstanding  principal  amount of any such
Letters of Credit which have not  expired.  Any portion of the amount so paid to
Lender which is not applied to satisfy draws under any such Letters of Credit or
any other  obligations  of  Borrower  to the Lender  shall be repaid to Borrower
without interest.


Lender's Costs and Expenses. Borrower shall, upon Lender's request, promptly pay
to and  reimburse  Lender for all costs  incurred and payments made by Lender by
reason of any future assessment, reserve, deposit, or similar requirement or any
surcharge, tax, or fee imposed upon Lender or as a result of Lender's compliance
with any directive or  requirement  of any  regulatory  authority  pertaining or
relating to any Letter of Credit.


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 others,
if  required)  shall grant to Lender  Security  Interests  in such  property and
assets as Lender may require (the "Collateral").  Lender's Security Interests in
the  Collateral  shall be  continuing  liens and shall  include the proceeds and
products of the  Collateral,  including  without  limitation the proceeds of any
insurance.  With respect to the  Collateral,  Borrower agrees and represents and
warrants to Lender: Perfection of Security Interests. Borrower agrees to execute
such  financing  statements  and to take whatever other actions are requested by
Lender to perfect and continue  Lender's  Security  Interests in the Collateral.
Upon  request  of  Lender,  Borrower  will  deliver to Lender any and all of the
documents  evidencing or  constituting  the  Collateral,  and Borrower will note
Lender's  interest upon any and all chattel paper if not delivered to Lender for
possession  by Lender.  Contemporaneous  with the  execution of this  Agreement,
Borrower  will  execute  one or more UCC  financing  statements  and any similar
statements  as may be required by applicable  law, and will file such  financing
statements  and all such  similar  statements  in the  appropriate  location  or
locations.  Borrower hereby appoints Lender as its irrevocable  attorney-in-fact
for the purpose of executing any  documents  necessary to perfect or to continue
any Security Interest. Lender may at any time, and without further authorization
from Borrower,  file a carbon,  photograph,  facsimile, or other reproduction of
any  financing  statement  for  use  as a  financing  statement.  Borrower  will
reimburse  Lender for all  expenses  for the  perfection,  termination,  and the
continuation of the perfection of Lender's  security interest in the Collateral.
Borrower  promptly will notify Lender of any change in Borrower's name including
any change to the assumed  business  names of Borrower.  Borrower  also promptly
will  notify  Lender  of any  change in  Borrower's  Social  Security  Number or
Employer  Identification  Number.  Borrower  further  agrees to notify Lender in
writing  prior to any change in  address or  location  of  Borrower's  principal
governance office or should Borrower merge or consolidate with any other entity.

Collateral  Records.  Borrower does now, and at all times hereafter shall,  keep
correct and accurate  records of the  Collateral,  all of which records shall be
available to Lender or Lender's  representative  upon demand for  inspection and
copying at any reasonable time.

Collateral  Schedules.  Concurrently  with the  execution  and  delivery of this
Agreement,   Borrower  shall  execute  and  deliver  to  Lender  a  schedule  of
Collateral,  in form and substance satisfactory to the Lender. Thereafter and at
such frequency as Lender shall require.


REPRESENTATIONS  AND WARRANTIES.  Borrower represents and warrants to Lender, as

binding upon Borrower or (b) any law, governmental regulation,  court decree, or
order applicable to Borrower.

financial  condition  subsequent  to the  date  of  the  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  will  constitute,

about or from any of the properties. (b) Borrower has no knowledge of, or reason
to believe that there has been (i) any use,  generation,  manufacture,  storage,

including without  limitation those laws,  regulations and ordinances  described

make such  inspections  and tests as Lender may deem  appropriate  to  determine
compliance of the properties with this section 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.

generation,  manufacture,  storage,  disposal,  release  or  threatened  release
occurring prior to Borrower's  ownership or interest in the properties,  whether
or not the same was or should have been known to  Borrower.  The  provisions  of
this section of the  Agreement,  including the  obligation  to indemnify,  shall
survive the payment of the  Indebtedness  and the  termination  or expiration of
this Agreement and shall not be affected by Lender's acquisition of any interest

Borrower that are or were required to be filed,  have been filed, and all taxes,

presently  being or to be  contested  by Borrower in good faith in the  ordinary
course of business and for which adequate reserves have been provided.

Borrower has not entered into or granted any Security  Agreements,  or permitted
the filing or  attachment  of any Security  Interests on or affecting any of the

Note,  that  would  be  prior or that  may in any way be  superior  to  Lender's
Security Interests and rights in and to such Collateral.

Binding Effect.  This Agreement,  the Note, all Security  Agreements directly or
indirectly securing repayment of Borrower's Loan and Note and all of the Related
Documents  are  binding  upon  Borrower as well as upon  Borrower's  successors,

business or commercial related purposes.

certified;  and none of such information is or will be incomplete by omitting to
state any material fact necessary to make such information not misleading.

Survival of Representations and Warranties. Borrower understands and agrees that
Lender,   without   independent   investigation,   is  relying  upon  the  above
representations and warranties in extending Loan Advances to Borrower.  Borrower
further  agrees  that the  foregoing  representations  and  warranties  shall be

upon  any of  Borrower's  properties,  income,  or  profits.  Provided  however,
Borrower  will not be required to pay and discharge  any such  assessment,  tax,
charge,  levy,  lien or claim so long as (a) the  legality  of the same shall be
contested in good faith by appropriate proceedings,  and (b) Borrower shall have
established  on its books  adequate  reserves  with  respect  to such  contested
assessment,  tax,  charge,  levy,  lien, or claim in accordance  with  generally
accepted accounting practices.  Borrower, upon demand of Lender, will furnish to
Lender evidence of payment of the assessments, taxes, charges, levies, liens and
claims and will authorize the  appropriate  governmental  official to deliver to
Lender at any time a  written  statement  of any  assessments,  taxes,  charges,
levies, liens and claims against Borrower's properties, income, or profits.

Performance.  Perform and comply with all terms, conditions,  and provisions set

same  qualifications  and  experience as the present  executive  and  management
personnel;  provide  written  notice to Lender of any  change in  executive  and
management  personnel;  conduct its business affairs in a reasonable and prudent
manner and in compliance with all applicable federal,  state and municipal laws,
ordinances,   rules  and  regulations   respecting  its  properties,   charters,

Borrower now or at any time hereafter  maintains any records  (including without
limitation  computer  generated  records and computer  software programs for the
generation of such records) in the possession of a third party,  Borrower,  upon
request of Lender,  shall notify such party to permit Lender free access to such
records at all reasonable times and to provide Lender with copies of any records
it may request, all at Borrower's expense.

all  environmental   protection  federal,   state  and  local  laws,   statutes,
regulations  and  ordinances;  not cause or  permit to exist,  as a result of an
intentional  or  unintentional  action or omission on its part or on the part of
any  third  party,   on  property  owned  and/or   occupied  by  Borrower,   any
environmental  activity where damage may result to the environment,  unless such
environmental activity is pursuant to and in compliance with the conditions of a
permit  issued  by  the  appropriate   federal,   state  or  local  governmental
authorities;  shall  furnish to Lender  promptly and in any event within  thirty
(30) days after receipt thereof a copy of any notice,  summons,  lien, citation,
directive,  letter  or other  communication  from  any  governmental  agency  or

on Borrower's part in connection with any environmental  activity whether or not
there is damage to the environment and/or other natural resources.

Additional  Assurances.  Make,  execute and  deliver to Lender  such  promissory
notes,  mortgages,  deeds of trust,  security agreements,  financing statements,
instruments,  documents  and other  agreements  as Lender or its  attorneys  may
reasonably  request to evidence and secure the Loans and to perfect all Security
Interests.

RECOVERY OF  ADDITIONAL  COSTS.  If the  imposition of or any change in any law,
rule,  regulation or guideline,  or the  interpretation  or  application  of any
thereof by any court or administrative or governmental  authority (including any
request or policy not  having  the force of law)  shall  impose,  modify or make
applicable  any taxes (except U.S.  federal,  state or local income or franchise
taxes imposed on Lender), reserve requirements, capital adequacy requirements or
other  obligations  which would (a) increase the cost to Lender for extending or
maintaining the credit  facilities to which this Agreement  relates,  (b) reduce
the amounts payable to Lender under this Agreement or the Related Documents,  or

obligations  with  respect to the  credit  facilities  to which  this  Agreement
relates,  then  Borrower  agrees to pay Lender such  additional  amounts as will
compensate  Lender therefor,  within five (5) days after Lender's written demand
for such payment,  which demand shall be  accompanied  by an explanation of such
imposition or charge and a calculation  in reasonable  detail of the  additional
amounts  payable  by  Borrower,  which  explanation  and  calculations  shall be

Code of 1986, as amended),  Borrower may pay cash  dividends on its stock to its
shareholders  from time to time in amounts  necessary to enable the shareholders
to pay income  taxes and make  estimated  income tax  payments to satisfy  their
liabilities  under federal and state law which arise solely from their status as

of stock of Borrower,  or (d) purchase or retire any of  Borrower's  outstanding

any of the  Related  Documents  or any  other  agreement  that  Borrower  or any
Guarantor  has with Lender;  (b) Borrower or any  Guarantor  becomes  insolvent,
files a  petition  in  bankruptcy  or  similar  proceedings,  or is  adjudged  a
bankrupt;  (c) there occurs a material  adverse  change in Borrower's  financial
condition,  in the financial condition of any Guarantor,  or in the value of any
Collateral  securing  any Loan;  (d) any  Guarantor  seeks,  claims or otherwise
attempts to limit, modify or revoke such Guarantor's guaranty of the Loan or any
other loan with Lender; or (e) Lender in good faith deems itself insecure,  even
though no Event of Default shall have occurred.

supersedes that certain  Business Loan Agreement,  dated as of July 26, 1995, as
it may be amended from time to time, between Borrower and Lender.

the aggregate  current  portion of long-term debt plus interest  expense) of not
less than 1.50 to 1.00.

(e)  Profitability.  Borrower shall generate a net profit at the end of each

operations and cash flows for the periods indicated in conformity with generally
accepted accounting principles applied on a basis consistent with prior years.

interest in, and hereby assigns,  conveys,  delivers,  pledges, and transfers to
Lender all Borrower's right,  title and interest in and to, Borrower's  accounts
with  Lender  (whether  checking,  savings,  or some other  account),  including
without  limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future,  excluding  however all IRA and Keogh accounts,
and all trust  accounts  for which the  grant of a  security  interest  would be
prohibited  by law.  Borrower  authorizes  Lender,  to the extent  permitted  by
applicable law, to charge or setoff all sums owing on the  Indebtedness  against
any and all such accounts.

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

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.

Events Affecting  Guarantor.  Any of the preceding events occurs with respect to

Guaranty of the Indebtedness.

Change In Ownership.  Any change in ownership of twenty-five percent (25%) or
more of the common stock of Borrower.

condition, or Lender believes the prospect of payment or performance of the
Indebtedness is impaired.

Insecurity.  Lender, in good faith, deems itself insecure.

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.

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,  Borrower agrees upon
Lender's  request to submit to the  jurisdiction  of the  courts of LOS  ANGELES
County, the State of California.  Subject to the provisions on arbitration, this
Agreement  shall be governed by and construed in accordance with the laws of the
State of California.

Arbitration.   Lender  and  Borrower   agree  that  all  disputes,   claims  and
controversies  between  them,  whether  individual,  joint,  or class in nature,
arising from this Agreement or otherwise,  including without limitation contract
and tort  disputes,  shall be  arbitrated  pursuant to the Rules of the American
Arbitration Association, upon request of either party. No act to take or dispose
of any Collateral shall constitute a waiver of this arbitration  agreement or be
prohibited by this arbitration  agreement.  This includes,  without  limitation,
obtaining injunctive relief or a temporary  restraining order;  invoking a power
of sale under any deed of trust or mortgage;  obtaining a writ of  attachment or
imposition  of a  receiver;  or  exercising  any  rights  relating  to  personal
property,  including  taking  or  disposing  of such  property  with or  without
judicial  process  pursuant to Article 9 of the  Uniform  Commercial  Code.  Any
disputes,  claims, or controversies  concerning the lawfulness or reasonableness
of any act, or exercise of any right,  concerning any Collateral,  including any
claim to rescind,  reform,  or otherwise  modify any  agreement  relating to the
Collateral, shall also be arbitrated,  provided however that no arbitrator shall
have the right or the power to enjoin or restrain  any act of any party.  Lender
and  Borrower  agree  that in the event of an action  for  judicial  foreclosure
pursuant  to  California  Code of Civil  Procedure  Section  726, or any similar
provision  in any other  state,  the  commencement  of such an  action  will not
constitute  a waiver of the right to  arbitrate  and the  court  shall  refer to
arbitration as much of such action, including counterclaims,  as lawfully may be
referred to arbitration.  Judgment upon any award rendered by any arbitrator may
be entered in any court having  jurisdiction.  Nothing in this  Agreement  shall
preclude  any party from  seeking  equitable  relief  from a court of  competent
jurisdiction. The statute of limitations,  estoppel, waiver, laches, and similar
doctrines  which would  otherwise be applicable in an action  brought by a party
shall be applicable in any arbitration  proceeding,  and the  commencement of an
arbitration  proceeding  shall be deemed the commencement of an action for these
purposes.   The  Federal  Arbitration  Act  shall  apply  to  the  construction,
interpretation, and enforcement of this arbitration provision.

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 Borrower under this
Agreement shall be joint and several,  and all references to Borrower shall mean
each and every  Borrower.  This means that each of the persons  signing below is
responsible for all obligations in this Agreement.

Consent to Loan Participation.  Borrower agrees and consents to Lender's sale or
transfer,  whether now or later, of one or more  participation  interests in the
Loans to one or more purchasers,  whether related or unrelated to Lender. Lender
may provide,  without any limitation whatsoever,  to any one or more purchasers,
or potential  purchasers,  any  information  or knowledge  Lender may have about
Borrower or about any other matter  relating to the Loan,  and  Borrower  hereby
waives any rights to privacy it may have with respect to such matters.  Borrower
additionally waives any and all notices of sale of participation  interests,  as
well as all notices of any repurchase of such participation interests.  Borrower
also agrees that the  purchasers  of any such  participation  interests  will be
considered as the absolute  owners of such  interests in the Loans and will have
all the rights granted under the participation agreement or agreements governing
the sale of such participation interests.  Borrower further waives all rights of
offset or  counterclaim  that it may have now or later against Lender or against
any purchaser of such a participation  interest and unconditionally  agrees that
either Lender or such  purchaser  may enforce  Borrower's  obligation  under the
Loans irrespective of the failure or insolvency of any holder of any interest in
the Loans.  Borrower further agrees that the purchaser of any such participation
interests  may enforce its  interests  irrespective  of any  personal  claims or
defenses that Borrower may have against Lender.

Costs and Expenses. Borrower agrees to pay upon demand all of Lender's expenses,
including without  limitation  attorneys' fees,  incurred in connection with the
preparation,  execution,  enforcement,   modification  and  collection  of  this
Agreement  or in  connection  with the Loans made  pursuant  to this  Agreement.
Lender  may pay  someone  else to help  collect  the Loans and to  enforce  this
Agreement,  and Borrower  will pay 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 for
bankruptcy proceedings (including efforts to modify or vacate any automatic stay
or injunction),  appeals, and any anticipated post-judgment collection services.
Borrower  also will pay any court costs,  in addition to all other sums provided
by law.

Notices. All notices required to be given under this Agreement shall be given in
writing,  may be sent by telefacsimile  (unless otherwise  required by law), 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 Borrower,  notice to any
Borrower will constitute notice to all Borrowers. For notice purposes,  Borrower
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 in the sole discretion of Lender.
