and zero (0) days late. The date specified in a purchase  order,  or required in
an  addendum,  is the date  due in  house.  A Kanban  part,  as  defined  in the
addendum,  may be delivered  only after the supplier is signaled in the business
system software. Kanban parts may be delivered anytime prior to the due date and
zero (0) days late,  where the due date is defined  in the  addendum.  Seller is
responsible for all costs  associated  with expedited  delivery when the need to

                              Contract Number: 1009

10. SHIPPING

The goods described herein shall be delivered FOB Garland TX. Buyer's Purchasing
Agent or Commodity Manager shall authorize means of shipment.  If seller chooses
alternative  method  of  shipment  without  Buyer's  authorization,   Seller  is
responsible for any incremental shipping charges.

11. KANBAN PULL PROCESS

Seller will  participate in a Kanban pull process for  specifically  agreed upon
part  numbers,  as listed in  addendum.  This list will be  updated as parts are
added to or deleted from the Kanban  program,  with agreement  between Buyer and
Seller.

Buyer's authorized  Purchasing Agent or Commodity Manager and Seller shall agree
on the Kanban quantity and replenishment  strategy for each part number.  Kanban
quantities  for all part  numbers  will be  reviewed  by Buyer on an as required
basis and  adjusted  accordingly.  Buyer's  quantity of  Finished  Goods Bins is
subject  to change  dependent  upon  Seller's  ability  to reduce  manufacturing
lead-time.  Changing the quantity of Finished Goods Bins at the buyer's facility
does not  necessitate  re-negotiation  of this  contact.  Seller  agrees that no
shipments will be made to Buyer unless authorized by Buyer.

12. PURCHASE ORDER

Buyer  will also be  entitled  to issue  purchase  orders for  individual  items
separate  from the Kanban Pull process and the Schedule  Agreement  Process,  as
quoted by Seller and agreed to in writing by Buyer.

13. SCHEDULE AGREEMENT

Schedule  Agreements  will be issued  with  agreement  by Buyer and Seller for a
specific time frame, by part number, negotiated price and estimate annual usage.
Buyer shall provide  Seller with demand  information as part of the planning and
forecasting  process,  to be updated  periodically  as agreed  upon by Buyer and
Seller.  This report is for use as a planning tool only.  Seller is  responsible
for any and all material purchased beyond the agreed upon liabilities, as stated
in addendum.

14. LIMITATION OF MATERIAL LIAB1LITY

The extent and limitation of Buyer's liability for materials purchased by Seller
are as defined in the  addendum.  On all  standard  or non-NCNR  parts,  AE will
assume

No liability. When the size of a bin is reduced, the inventory liability will be
a  function  of the old bin size  minus  pulls.  The goal is to  consume  excess
inventory  driven  by the old bin size  down to the new bin size  liability.  At
which point,  this would become the contractual  addendum amount AE is liable to
purchase.  AE's  expectation  is that the  seller's  supply  chain be  decreased
accordingly and consistently.

Principal Amount: $3,000,000.00                       Date of Note: June 5, 2004

PROMISE TO PAY. MICROPAC INDUSTRIES,  INC.  ("Borrower")  promises to pay to THE
FROST NATIONAL BANK  ("Lender"),  or order, in lawful money of the United States
of  America,   the  principal   amount  of  Three   Million  &  00/100   Dollars
($3,000,000.00) 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 or
maturity, whichever occurs first.

CHOICE OF USURY  CEILING AND INTEREST  RATE.The  interest  rate on this Note has
been  implemented  under the "Weekly Ceiling" as referred to in Sections 303.002
and 303.003 of the Texas Finance Code. The terms,  including the rate, or index,
formula,  or  provision  of law used to  compute  the rate on the Note,  will be
subject to  revision  as to current  and future  balances,  from time to time by
notice from Lender in compliance with Section 303.103 of the Texas Finance Code.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal
plus all accrued unpaid interest on June 1, 2005. In addition, Borrower will pay
regular  monthly  payments of all accrued unpaid interest due as of each payment
date, beginning July 5, 2004, with all subsequent interest payments to be due on
the same day of each month after that.  Unless  otherwise  agreed or required by
applicable law,  payments will be applied first to any unpaid  collection costs;
then to any late  charges;  then to any  accrued  unpaid  interest;  and then to
principal.  The  annual  interest  rate for this Note is  computed  on a 365/360
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,  unless  such
calculation  would result in a usurious  rate, in which case  interest  shall be
calculated on a per diem basis of a year of 365 or 366 days, as the case may be.
Borrower will pay Lender at Lender's  address shown above or at such other place
as Lender may designate in writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time  based on  changes in an index  which is  Lender's  Prime Rate (the
"Index").  This is the rate Lender charges, or would charge, on 90-day unsecured
loans to the most creditworthy corporate customers.  This rate may or may not be
the lowest  rate  available  from  Lender at any given  time.  Lender  will tell
Borrower the current  Index rate upon  Borrower's  request.  The  interest  rate
change will not occur more often than each day. Borrower understands that Lender
may make loans based on other  rates as well.  The  interest  rate to be applied
prior to maturity to the unpaid principal balance of this Note will be at a rate
of 0.250 percentage points under the Index.  NOTICE: Under no circumstances will
the  interest  rate on this  Note be more  than  the  maximum  rate  allowed  by
applicable  law.  For  purposes  of this  Note,  the  "maximum  rate  allowed by
applicable  law" means the greater of (A)the maximum rate of interest  permitted
under  federal or other law  applicable  to the  indebtedness  evidenced by this
Note, or (B) the "Weekly Ceiling" as referred to in Sections 303.002 and 303.003
of the Texas Finance Code.

<PAGE>

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed
earlier  than it is due.  Prepayment  in full  shall  consist  of payment of the
remaining unpaid principal balance together with all accrued and unpaid interest
and all other  amounts,  costs and  expenses for which  Borrower is  responsible
under this Note or any other agreement with Lender  pertaining to this loan, and
in no event will Borrower ever be required to pay any unearned  interest.  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,  early payments will reduce the principal  balance due.  Borrower agrees
not to send  Lender  payments  marked  "paid in full",  "without  recourse",  or
similar language. If Borrower sends such a payment, Lender may accept it without
losing any of  Lender's  rights  under  this  Note,  and  Borrower  will  remain
obligated to pay any further amount owed to Lender.  All written  communications
concerning  disputed  amounts,  including any check or other payment  instrument
that indicates that the payment constitutes "payment in full" of the amount owed
or that is tendered with other conditions or limitations or as full satisfaction
of a disputed  amount must be mailed or delivered to: THE FROST  NATIONAL  BANK,
P.O. BOX 1600 SAN ANTONIO, TX 78296.

LATE  CHARGE.  If a payment  is 11 days or more late,  Borrower  will be charged
5.000% of the unpaid  portion of the  regularly  scheduled  payment or  $250.00,
whichever is less.

POST  MATURITY  RATE.  The Post  Maturity Rate on this Note is the lesser of the
maximum rate allowed by applicable  law or 18.000% per annum.  Borrower will pay
interest  on all sums due after  final  maturity,  whether  by  acceleration  or
otherwise, at that rate.

DEFAULT.  Each of the following shall  constitute an event of default ("Event of
Default") under this Note:

         Payment Default. Borrower fails to make any payment when due under this
         Note.

         Other  Defaults.  Borrower fails to comply with or to perform any other

         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.

         False  Statements.  Any warranty,  representation  or statement made or
         furnished to Lender by Borrower or on Borrower's behalf under this Note

         respect,  either now or at the time made or furnished or becomes  false
         or misleading at any time thereafter.

         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

         includes a garnishment of any of Borrower's accounts, including deposit
         accounts,  with Lender.  However, this Event of Default shall not apply
         if there is a good faith  dispute by  Borrower  as to the  validity  or
         reasonableness  of the  claim  which is the  basis of the  creditor  or
         forfeiture  proceeding  and if Borrower  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.

GENERAL PROVISIONS.  If any part of this Note cannot be enforced, this fact will
not affect the rest of the Note.  Borrower  does not agree or intend to pay, and
Lender does not agree or intend to contract for, charge,  collect, take, reserve
or receive (collectively referred to herein as "charge or collect"),  any amount
in the nature of interest  or in the nature of a fee for this loan,  which would
in any way or event (including demand, prepayment, or acceleration) cause Lender
to  charge  or  collect  more for this loan  than the  maximum  lender  would be
permitted  to charge or collect by federal  law or the law of the State of Texas
(as applicable).  Any such excess interest or unauthorized fee shall, instead of
anything  stated to the  contrary,  be  applied  first to reduce  the  principal
balance of this loan,  and when the principal has been paid in full, be refunded
to Borrower.  The right to accelerate  maturity of sums due under this Note does
not include the right to accelerate any interest which has not otherwise accrued
on the date of such  acceleration,  and  Lender  does not  intend  to  charge or
collect any  unearned  interest in the event of  acceleration.  All sums paid or
agreed to be paid to Lender for the use,  forbearance  or  detention of sums due
hereunder  shall,  to the extent  permitted  by  applicable  law, be  amortized,
prorated, allocated and spread throughout the full term of the loan evidenced by
this  Note  until  payment  in full so that the rate or amount  of  interest  on
account  of the loan  evidenced  hereby  does not exceed  the  applicable  usury
ceiling. Lender may delay or forgo enforcing any of its rights or remedies under
this Note  without  losing  them.  Borrower  and any  other  person  who  signs,
guarantees  or  endorses  this  Note,  to  the  extent  allowed  by  law,  waive
presentment,  demand  for  payment,  notice  of  dishonor,  notice  of intent to
accelerate the maturity of this Note, and notice of acceleration of the maturity
of this Note.  Upon any change in the terms of this Note,  and unless  otherwise
expressly  stated in  writing,  no party who signs this Note,  whether as maker,
guarantor,  accommodation  maker or endorser,  shall be released from liability.
All such parties agree that Lender may renew or extend  (repeatedly  and for any

<PAGE>

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  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. The obligations
under this Note are joint and several.

PRIOR TO SIGNING THIS NOTE,  BORROWER READ AND  UNDERSTOOD ALL THE PROVISIONS OF

         agreement  Borrower  is  required  to give  under this  Agreement  when
         delivered will  constitute  legal,  valid,  and binding  obligations of
         Borrower   enforceable   against  Borrower  in  accordance  with  their
         respective terms.

         Properties.  Except as  contemplated by this Agreement or as previously

         person relating to such matters.  (3) Neither  Borrower nor any tenant,
         contractor,  agent or other  authorized  user of any of the  Collateral
         shall use, generate,  manufacture,  store, treat, dispose of or release
         any Hazardous Substance on, under, about or from any of the Collateral;
         and any  such  activity  shall  be  conducted  in  compliance  with all
         applicable federal, state, and local laws, regulations, and ordinances,

         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 Collateral for
         hazardous waste and Hazardous Substances.  Borrower hereby (1) releases
         and  waives  any  future  claims   against   Lender  for  indemnity  or
         contribution in the event Borrower  becomes liable for cleanup or other
         costs  under  any such  laws,  and (2)  agrees  to  indemnify  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 release of a hazardous waste
         or substance on the  Collateral.  The provisions of this section of the
         Agreement,  including the  obligation  to indemnify,  shall survive the
         payment  of  the  Indebtedness  and  the  termination,   expiration  or
         satisfaction  of this  Agreement  and shall not be affected by Lender's
         acquisition  of any  interest  in any of  the  Collateral,  whether  by
         foreclosure or otherwise.

         Litigation   and   Claims.   No   litigation,   claim,   investigation,
         administrative proceeding or similar action (including those for unpaid
         taxes) against  Borrower is pending or  threatened,  and no other event
         has occurred which may materially adversely affect Borrower's financial
         condition  or  properties,  other  than  litigation,  claims,  or other
         events,  if any, that have been disclosed to and acknowledged by Lender
         in writing.

         writing,  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 Collateral  directly or indirectly
         securing  repayment of Borrower's Loan and 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.

         any), and all Related  Documents are binding upon the signers  thereof,

                           Quick  Ratio.  Maintain  a Quick  Ratio in  excess of
                           1.000  to  1.000.   The  term  "Quick   Ratio"  means
                           Borrower's  Cash &  Equivalent  plus  Borrower's  net
                           Trade Receivables divided by Borrower's total Current

                           not in excess of 1.250 to  1.000.  The ratio  "Debt /
                           Worth" means Borrower's Total Liabilities  divided by
                           Borrower's Tangible Net Worth,

                  Except as provided above, all  computations  made to determine
                  compliance with the  requirements  contained in this paragraph
                  shall be made in accordance with generally accepted accounting
                  principles,  applied on a consistent  basis,  and certified by
                  Borrower as being true and correct.

         Insurance.  Maintain fire and other risk  insurance,  public  liability
         insurance,  and such other insurance as Lender may require with respect
         to  Borrower's  properties  and  operations,   in  form,  amounts,  and
         coverages  reasonably  acceptable to Lender and by insurance  companies
         authorized  to  transact  business in Texas.  BORROWER  MAY FURNISH THE
         INSURANCE  REQUIRED BY THIS AGREEMENT WHETHER THROUGH EXISTING POLICIES
         OWNED OR CONTROLLED BY BORROWER OR THROUGH EQUIVALENT COVERAGE FROM ANY
         INSURANCE COMPANY  AUTHORIZED TO TRANSACT BUSINESS IN TEXAS.  Borrower,
         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.  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 Borrower or any other person. In
         connection  with all policies  covering assets in which Lender holds or
         is offered a security  interest  for the Loans,  Borrower  will provide
         Lender with such lender's loss payable or other  endorsements as Lender
         may require.

         manner of determining those values;  and (6) the expiration date of the
         policy.  In addition,  upon  request of Lender  (however not more often
         than   annually),   Borrower   will  have  an   independent   appraiser
         satisfactory to Lender determine, as applicable,  the actual cash value
         or replacement cost of any Collateral. The cost of such appraisal shall
         be paid by Borrower.

         default in connection with any agreement.

         Operations.   Maintain   executive  and   management   personnel   with

         expense,  all such investigations,  studies,  samplings and testings as

         any substance,  or any waste or by-product of any substance  defined as
         toxic or a hazardous  substance  under  applicable  federal,  state, or
         local law, rule,  regulation,  order or directive,  at or affecting any

         Compliance  with  Governmental  Requirements.  Comply  with  all  laws,
         ordinances,  and  regulations,  now  or  hereafter  in  effect,  of all
         governmental  authorities  applicable  to  the  conduct  of  Borrower's
         properties,  businesses and operations.  and to the use or occupancy of
         the  Collateral,  including  without  limitation,  the  Americans  With
         Disabilities  Act.  Borrower  may  contest  in good faith any such law,
         ordinance, or regulation and withhold compliance during any proceeding,
         including  appropriate appeals, so long as Borrower has notified Lender
         in writing  prior to doing so and so long as, in Lender's sole opinion,
         Lender's  interests in the Collateral are not  jeopardized.  Lender may
         require Borrower to post adequate security or a surety bond, reasonably
         satisfactory to Lender, to protect Lender's interest.

         accounts,  and  records.  If  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.

         quarter,  with a  certificate  executed by Borrower's  chief  financial
         officer,  or other officer or person  acceptable to Lender,  certifying
         that the representations and warranties set forth in this Agreement are
         true  and  correct  as of the  date  of  the  certificate  and  further
         certifying that, as of the date of the certificate, no Event of Default

<PAGE>

         Environmental  Compliance  and  Reports.  Borrower  shall comply in all
         respects with any and all  Environmental  Laws;  not cause or permit to
         exist,  as a  result  of an  intentional  or  unintentional  action  or
         omission  on  Borrower's  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  instrumentality  concerning any intentional or
         unintentional  action or omission on Borrower's part in connection with

         environment and/or other natural resources.

         Additional  Assurances.  Make,  execute  and  deliver  to  Lender  such
         promissory  notes,  mortgages,  deeds of  trust,  security  agreements.

         agreements  as  Lender  or its  attorneys  may  reasonably  request  to

LENDER'S  EXPENDITURES.  If any action or  proceeding  is  commenced  that would
materially  affect  Lender's  interest in the Collateral or if Borrower fails to
comply with any provision of this Agreement or any Related Documents,  including
but not limited to Borrower s failure to  discharge  or pay when due any amounts
Borrower is required to  discharge  or pay under this  Agreement  or any Related
Documents,  Lender on Borrower's behalf may (but shall not be obligated to) take
any  action  that  Lender  deems  appropriate,  including  but  not  limited  to
discharging or paying all taxes.  liens,  security  interests,  encumbrances and
other  claims,  at any time  levied or placed on any  Collateral  and paying all
costs  for  insuring,  maintaining  and  preserving  any  Collateral.  All  such
expenditures  paid by Lender for such  purposes  will then beer  interest at the
Note rate from the date paid by Lender to the date of repayment by Borrower.  To
the extent  permitted by applicable law, all such expenses will become a part of
the Indebtedness and, at Lender's option, will (A) be payable on demand; o(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  (1) the term of any
applicable  insurance  policy;  or (2) 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.

NEGATIVE  COVENANTS.  Borrower  covenants and agrees with Lender that while this
Agreement is in effect, Borrower shall not, without the prior written consent of
Lender:

         Indebtedness  and Liens.  (1) Except  for trade  debt  incurred  in the
         normal course of business and  indebtedness  to Lender  contemplated by

         money, including capital leases, (2) sell, transfer,  mortgage, assign,
         pledge,  lease,  grant a  security  interest  in,  or  encumber  any of
         Borrower's  assets (except as allowed as Permitted  Liens), or (3) sell
         with recourse any of Borrower's accounts, except to Lender.

         Continuity  of  Operations.  (1)  Engage  in  any  business  activities

         consolidate  with any  other  entity,  change  its  name.  dissolve  or
         transfer or sell Collateral out of the ordinary course of business,  or
         (3) pay any dividends on Borrower's stock (other than dividends payable
         in its stock),  provided,  however that  notwithstanding the foregoing,
         but only so long as no Event of Default has occurred and is  continuing
         or would  result  from the  payment  of  dividends,  if  Borrower  is a
         "Subchapter S Corporation"  (as defined in the Internal Revenue 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  Shareholders of a Subchapter S Corporation
         because of their  ownership of shares of Borrower's  stock, or purchase
         or  retire  any of  Borrower's  outstanding  shares  or  alter or amend
         Borrower's capital structure.

         Loans.  Acquisitions  and  Guaranties.  (1) Loan,  invest in or advance
         money or assets,  (2)  purchase,  create or acquire any interest in any
         other  enterprise or entity,  or (3) incur any  obligation as surety or
         guarantor other than in the ordinary course of business.

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.

RIGHT OF SETOFF.  To the extent  permitted by applicable  law, Lender reserves a
right of  setoff in all  Borrower's  accounts  with  Lender  (whether  checking,
savings,  or some other  account).  This  includes all accounts  Borrower  holds
jointly  with  someone  else and all  accounts  Borrower may open in the future.
However,  this does not include any IRA or Keogh accounts, or any trust accounts
for which setoff would be prohibited by law. Borrower  authorizes Lender, to the
extent  permitted by  applicable  law, to charge or setoff all sums owing on the
debt against any and all such accounts.

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

         Payment Default.  Borrower fails to make any payment when due under the
         Loan.

         in any of the  Related  Documents  or to comply  with or to perform any
         term,  obligation.   covenant  or  condition  contained  in  any  other
         agreement between Lender and Borrower.

         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 or any Grantor'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 Borrower  or on  Borrower's  behalf  under this
         Agreement  or the  Related  Documents  is  false or  misleading  in any
         material  respect,  either  now or at the  time  made or  furnished  or
         becomes false or misleading at any time thereafter.

         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

         Documents ceases to be in full force and effect  (including  failure of
         any  collateral  document  to  create a valid  and  perfected  security
         interest or lien) at any time and for any reason.

         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 or by any
         governmental  agency  against any  collateral  securing the Loan.  This
         includes a garnishment of any of Borrower's accounts, including deposit
         accounts,  with Lender.  However, this Event of Default shall not apply
         if there is a good faith  dispute by  Borrower  as to the  validity  or
         reasonableness  of the  claim  which is the  basis of the  creditor  or
         forfeiture  proceeding  and if Borrower  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 any Guarantor

         Insecurity. Lender in good faith believes itself insecure.

<PAGE>

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
further  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.

accordance with generally accepted  accounting  principles) less all intangibles
and inter-company receivables.

paragraph  entitled  "Indebtedness  and Liens" under Section entitled  "Negative
Covenants"  Borrower shall be permitted to incur additonal  indebtedness for the
purpose of purchase  money  security  interests and capital  leases  without the
consent of Lender.

         enforcement of this  Agreement.  Lender may hire or pay someone else to
         help  enforce  this  Agreement,  and  Borrower  shall pay the costs and

         vacate any automatic stay or injunction),  appeals, and any anticipated
         post-judgment  collection  services.  Borrower 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.

         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 Loan 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  Borrower  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 Loan 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 Loan  irrespective  of the failure or
         insolvency of any holder of any interest in the Loan.  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.

         Governing  Law.  This  Agreement  will be governed  by,  construed  and
         enforced in  accordance  with  federal law and the laws of the State of

         Choice  of  Venue.  If  there  is a  lawsuit,  and if  the  transaction
         evidenced by this Agreement  occurred in BEXAR County,  Borrower agrees
         upon Lender's  request to submit to the  jurisdiction  of the Courts of
         BEXAR County, State of Texas.

         No Waiver by  Lender.  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 of  Borrower's
         or any Grantor's  obligations 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 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.

         Notices.  Any notice required to be given under this Agreement shall be
         given in writing, and shall be effective when actually delivered,  when
         actually received by telefacsimile  (unless otherwise required by law),
         when deposited with a nationally  recognized  overnight courier, or, if
         mailed,  when  deposited  in the United  States  mail,  as first class,
         certified or registered mail postage prepaid, directed to the addresses
         shown near the  beginning of this  Agreement.  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. For notice purposes,  Borrower agrees
         to keep Lender  informed at all times of  Borrower's  current  address.
         Unless otherwise provided or required by law, if there is more than one
         Borrower,  any notice  given by Lender to any  Borrower is deemed to be
         notice given to all Borrowers.

         Payment of Interest and Fees.  Notwithstanding  any other  provision of
         this Agreement or any provision of any Related Document,  Borrower does
         not  agree or  intend to pay,  and  Lender  does not agree or intend to
         charge,  collect,  take, reserve or receive  (collectively  referred to
         herein as "charge or collect"), any amount in the nature of interest or
         in the  nature  of a fee for the Loan  which  would in any way or event
         (including  demand,   prepayment,  or  acceleration)  cause  Lender  to
         contract  for,  charge or  collect  more for the Loan than the  maximum
         Lender  would be  permitted  to charge  or  collect  by any  applicable
         federal or Texas state law.  Any such excess  interest or  unauthorized
         fee will, instead of anything stated to the contrary,  be applied first
         to reduce  the  unpaid  principal  balance  of the  Loan,  and when the
         principal has been paid in full, be refunded to Borrower.

         Severability.  If a Court of Competent jurisdiction finds any provision
         of this Agreement to be illegal,  invalid,  or  unenforceable as to any
         circumstance,  that  finding  shall  not make the  offending  provision
         illegal,  invalid,  or unenforceable as to any other  circumstance.  If
         feasible,  the offending provision shall be considered modified so that
         it becomes legal,  valid and  enforceable.  If the offending  provision
         cannot  be so  modified,  it  shall be  considered  deleted  from  this
         Agreement.   Unless   otherwise   required  by  law,  the   illegality,
         invalidity,  or  unenforceability  of any  provision of this  Agreement
         shall not affect the legality,  validity or enforceability of any other
         provision of this Agreement.

         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 in this  Agreement  shall include all of Borrower's
         subsidiaries  and affiliates.  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 of
         Borrower's subsidiaries or affiliates.

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

         Survival of Representations  and Warranties.  Borrower  understands and
         agrees  that in  extending  Loan  Advances,  Lender is  relying  on all
         representations,  warranties,  and  covenants  made by Borrower in this
         Agreement  or in any  certificate  or  other  instrument  delivered  by
         Borrower  to Lender  under this  Agreement  or the  Related  Documents.

<PAGE>

         Borrower  further agrees that regardless of any  investigation  made by
         Lender, all such representations. warranties and covenants will survive
         the  extension  of Loan  Advances and delivery to Lender of the Related
         Documents,  shall be  continuing  in nature,  shall be deemed  made and
         redated by  Borrower at the time each Loan  Advance is made,  and shall
         remain  in  full  force  and  effect  until  such  time  as  Borrower's
         Indebtedness  shall be paid in full, or until this  Agreement  shall be
         terminated  in the  manner  provided  above,  whichever  is the last to
         occur.
