                                              New York, New York, July 12, 2000

     WHEREAS,  HAUPPAUGE  DIGITAL,  INC. and  HAUPPAUGE  COMPUTER  WORKS,  INC.,
(together hereinafter called the "Borrower"),  desires to transact business with
and  to  obtain  credit  or  a  continuation   of  credit  or  other   financial
accommodations  from THE CHASE  MANHATTAN  BANK, a New York banking  corporation
(hereinafter called the "Bank"); and

     WHEREAS,  the Bank is  unwilling  to extend or continue  credit to or other
financial  accommodations  to the  Borrower,  unless it receives  the  following
guaranty of the undersigned;

     NOW,  THEREFORE,  in  consideration  of the  premises and of other good and
valuable consideration and in order to induce the Bank from time to time, in its
discretion,  to extend or continue credit or other financial  accommodations  to
the Borrower, the undersigned hereby guarantees, absolutely and unconditionally,
to the  Bank the  payment  of all  liabilities  of the  Borrower  to the Bank of
whatever nature,  whether now existing or thereafter  incurred,  whether created
directly or acquired by the Bank by assignment or otherwise,  whether matured or
unmatured  and  whether  absolute  or-contingent  (all of which are  hereinafter
collectively referred to as the "Liabilities of the Borrower").

     In order to further secure the payment of the  Liabilities of the Borrower,
the undersigned does hereby give the Bank a continuing lien and right of set-off
for the  amount of the  Liabilities  of the  Borrower  upon any and all  monies,
securities  arid any and all other property of the  undersigned and the proceeds
thereof,  now or hereafter actually or constructively  held or received by or in
transit in any manner to or from the Bank,  Chase  Securities Inc., or any other
affiliate  of the Bank from or for the  undersigned,  whether  for  safekeeping,
custody,  pledge,  transmission,  collection  or  otherwise  or coming  into the
possession of the Bank,  Chase  Securities  Inc., or any other  affiliate of the
Bank in any way,  or placed in any safe  deposit  box leased by the Bank,  Chase
Securities Inc., or any other affiliate of the Bank to the undersigned. The Bank
is also  given a  continuing  lien and right of  set-off  for the amount of said
Liabilities of the Borrower upon any and all deposits  (general and special) and
credits of, or for the benefit of the  undersigned  with, and any and all claims
of the  undersigned  against,  the Bank,  Chase  Securities  Inc.,  or any other
affiliate  of the Bank at any time  existing,  provided  an event of default has
occurred.  The Bank is hereby  authorized  at any time or times,  without  prior
notice,  to  apply  such  deposits  or  credits,  or any part  thereof,  to such
Liabilities of the Borrower and,  although said  Liabilities of the Borrower may
be contingent  or unmatured,  and whether the  collateral  security  therefor is
deemed adequate or not. The undersigned authorizes the Bank to deliver a copy of
this guaranty to others as written notification of the undersigned's transfer of
a security interest in the collateral described herein to the Bank.

     The  undersigned  agrees  that,  with or  without  notice  or  demand,  the
undersigned  shall  reimburse  the Bank for all the Bank's  reasonable  expenses
(including reasonable fees of counsel for the Bank who may be employees thereof)
incurred  in  connection  with any of the  Liabilities  of the  Borrower  or the
collection thereof.

     This  guaranty is a continuing  guaranty and shall remain in full force and
effect  irrespective  of any  interruptions  in the  business  relations  of the
Borrower with the Bank; provided,  however,  that the undersigned may, by notice
in writing,  delivered  personally or received by certified mail, return receipt
requested,  addressed to the Bank's  office at 52 Broadway,  New York,  New York
10004,  Loan  Services,  Attention:  Daniel Papa,  terminate  this guaranty with
respect  to all  Liabilities  of the  Borrower  incurred  or  contracted  by the
Borrower  or  acquired  by the Bank  after the date on which  such  notice is so
delivered or received.

     All monies available to the Bank for application in payment or reduction of
the Liabilities of the Borrower may be applied by the Bank in such manner and in
such  amounts  and at such  time or  times as it may see fit to the  payment  or
reduction of such of the Liabilities of the Borrower as the Bank may elect.

     The  undersigned  hereby waives:  (a) notice of acceptance of this guaranty
and of extensions of credit or other financial accommodations by the Bank to the
Borrower;  (b)  presentment  and demand for payment of any of the Liabilities of
the Borrower;  (c) protest and notice of dishonor or default to the  undersigned
or to any other party with respect to any of the  Liabilities  of the  Borrower;
(d) all other notices to which the  undersigned  may otherwise be entitled;  and
(e) any demand for payment hereunder.

     All  liabilities  of the  undersigned  to the Bank  hereunder or otherwise,
whether or not then due or  absolute  or  contingent,  shall  without  notice or
demand become due and payable  immediately upon the occurrence of any default or
event of  default  with  respect  to any  Liabilities  of the  Borrower  (or the
occurrence of any other event which results in  acceleration  of the maturity of
any thereof) or the occurrence of any default  hereunder.  This is a guaranty of
payment and not of collection  and the  undersigned  further waives any right to
require  that any action be brought  against the Borrower or any other person or
to require  that resort be had to any  security or to any balance of any deposit
account or credit on the books of the Bank in favor of the Borrower or any other
person.

     The undersigned hereby consents that from time to time, before or after any
default by the  Borrower or any notice of  termination  hereof,  with or without
further notice to or assent from the undersigned,  any security at any time held
by or available to the Bank for any obligation of the Borrower,  or any security
at any time held by or  available  to the Bank for any  obligation  of any other
person  secondarily  or  otherwise  liable  for  any of the  Liabilities  of the
Borrower,  may be exchanged,  surrendered  or released and any obligation of the
Borrower,  or of any  such  other  person,  may be  changed,  altered,  renewed,
extended, continued, surrendered, compromised, waived, discharged or released in
whole or in part (including without limitation any such event resulting from any
insolvency, bankruptcy, reorganization or other similar proceeding affecting the
Borrower or its assets) or any default with respect thereto waived, and the Bank
may fail to set off and may  release,  in whole or in part,  any  balance of any
deposit  account or credit on the Bank's books in favor of the  Borrower,  or of
any such other person, and may extend further credit in any manner whatsoever to
the Borrower,  and generally deal or take action or no action with regard to the
Borrower or any such  security or other  person as the Bank may see fit; and the
undersigned  shall remain  bound under this  guaranty  notwithstanding  any such
exchange,   surrender,   release,  change,   alteration,   renewal,   extension,
continuance,  compromise,  waiver,  discharge,  inaction,  extension  of further
credit or other dealing.

     The obligations of the undersigned are absolute and  unconditional  and are
valid  irrespective of any other agreement or circumstance which might otherwise
constitute  a defense to the  obligations  hereunder  or to the  obligations  of
others  related  thereto  and the  undersigned  irrevocably  waives the right to
assert defenses,  set-offs and counterclaims in any litigation  relating to this
guaranty and the  Liabilities  of the  Borrower.  This  guaranty  sets forth the
entire  understanding of the parties,  and the undersigned  acknowledges that no
oral or other agreements, conditions, promises, understandings,  representations
or  warranties  exist in  regard  to the  obligations  hereunder,  except  those
specifically set forth herein.

     The undersigned irrevocably waives and shall not seek to enforce or collect
upon any rights which it now has or may acquire against the Borrower,  either by
way of  subrogation,  indemnity,  reimbursement  or  contribution,  or any other
similar  right,  for any amount paid under this  guaranty or by way of any other
obligations whatsoever of the Borrower to the undersigned. In the event either a
petition  is filed  under the  Bankruptcy  Code in regard to the  Borrower or an
action or  proceeding  is  commenced  for the  benefit of the  creditors  of the
Borrower,  this  agreement  shall at all times  thereafter  remain  effective in
regard to any payments or other transfers of assets to the Bank received from or
on behalf of the Borrower  prior to notice of  termination  of this guaranty and
which are or may be held voidable or otherwise subject to recission or return on
the grounds of preference,  fraudulent  conveyance or otherwise,  whether or not
the Liabilities of the Borrower have been paid in full.

     Each reference herein to the Bank shall be deemed to include its successors
and assigns,  in whose favor the  provisions of this guaranty  shall also inure.
Each reference  herein to the undersigned  shall be deemed to include the heirs,
executors, administrators, legal representatives,  successors and assigns of the
undersigned, all of whom shall be bound by the provisions of this guaranty.

     The term  "undersigned"  as used herein shall, if this instrument is signed
by more  than one  party,  mean  the  "undersigned  and  each of them"  and each
undertaking  herein  contained  shall be their  joint and  several  undertaking,
provided,  however,  that in the  next  succeeding  paragraph  hereof  the  term
"undersigned"  shall mean the  "undersigned or any of them". If any party hereto
shall  be a  partnership,  the  agreements  and  obligations  on the part of the
undersigned  herein  contained shall remain in force and applicable  against the
partnership  and  all  of  its  partners  (notwithstanding  any  changes  in the
individuals  composing the  partnership  or any release of one or more partners)
and the term "undersigned"  shall include any altered or successive  partnership
but,  the  predecessor  partnerships  and their  partners  shall not  thereby be
released from any obligation or liability.

     No delay on the part of the Bank in  exercising  any  rights  hereunder  or
failure to exercise the same shall operate as a waiver of such rights; no notice
to or demand on the undersigned shall be deemed to be a waiver of the obligation
of the  undersigned  or of the right of the Bank to take further  action without
notice or demand as provided herein;  nor in any event shall any modification or
waiver of the provisions of this guaranty be effective  unless in writing signed
by an  authorized  officer of the Bank;  nor shall any such waiver be applicable
except in the specific instance for which given.

     This guaranty is, and shall be deemed to be, a contract  entered into under
and  pursuant to the laws of the State of New York and shall be in all  respects
governed,  construed,  applied and enforced in accordance  with the laws of said
State; and no defense given or allowed by the laws of any other State or Country
shall be  interposed  in any action  hereon unless such defense is also given or
allowed by the laws of the State of New York.

                                  (LIBOR/PRIME)

$6,500,000                                                    Melville, New York
                                                              July 12, 2000

     FOR VALUE RECEIVED,  HAUPPAUGE DIGITAL,  INC. and HAUPPAUGE COMPUTER WORKS,
INC. (the  "Borrowers"  and each, a "Borrower"),  hereby  promises to pay to the
order of THE CHASE  MANHATTAN BANK (the "Bank") at the office of the Bank at 395
N. Service Road, 3rd Floor,  Melville,  New York 11747, in immediately available
funds,  the  principal  amount of SIX  MILLION  FIVE  HUNDRED  THOUSAND  DOLLARS
($6,500,000)  or such lesser amount as may  constitute the  outstanding  balance
hereof,  in lawful money of the United  States,  on the earlier of (i) March 31,
2001 (the  "Termination  Date") or (ii) the date set forth in the Grid  Schedule
attached  hereto as the maturity date for a Loan (as  hereinafter  defined) made
hereunder ("Maturity Date") and interest on the same as hereinafter provided.

     Interest/Grid Schedule

     The Bank is authorized to enter on the Grid  Schedule  attached  hereto (i)
the amount of each Loan made from time to time hereunder, (ii) the date on which
each Loan is made, (iii) the date on which each Loan shall be due and payable to
the Bank which in no event shall be later than the  Termination  Date,  (iv) the
interest  rate agreed  between the Borrower and the Bank as the interest rate to
be paid to the Bank on each Loan  (each  such  rate,  the  "Applicable  Interest
Rate"), which rate, at the Borrower's option in accordance herewith, shall be at
(a) the Prime  Rate  (for  "Prime  Rate  Loan(s)"),  or (b) LIBOR (as  hereafter
defined) plus 1.25% (for "Eurodollar  Loan(s)"),  (v) the amount of each payment
made  hereunder,  and  (vi)  the  outstanding  principal  balance  of the  Loans
hereunder from time to time,  all of which  entries,  in the absence of manifest
error,  shall be  rebuttably  presumed  correct  and  binding  on the  Borrower;
provided,  however,  that the failure of the Bank to make any such entries shall
not relieve the Borrower from its obligation to pay any amount due hereunder.

          Prime Rate Loans

(a)       "Prime Rate  Loans"  shall mean a loan with  interest  accruing at
          Prime Rate.  "Prime Rate shall mean the rate of interest  as is
          publicly  announced at the Bank's  principal office from time to
          time as its  prime  commercial  lending  rate.  The  unpaid  principal
          balance of Prime Rate Loans will bear  interest  equal at all times to
          the Prime Rate per annum in effect  from time to time.  Interest is to
          be computed on an actual/360 day basis, including any time extended by
          reason of Saturdays,  Sundays and holidays.  Interest shall be payable
          in arrears on a monthly basis on the first day of each month.

                                        1

<PAGE>

          Eurodollar Loans

(b)       "Eurodollar Loans" shall mean a loan with interest accruing at the
          Eurodollar  loan rate. Each Eurodollar Loan shall be made available by
          the Bank to the Borrower  from the lending  office  designated  by the
          Bank, and shall be in a minimum amount of $500,000.  Interest shall be
          determined by the Bank for periods of one, two,  three,  or six months
          (the  "Interest  Period")  (as  selected by the  Borrower);  provided,
          however,  no Interest Period shall extend beyond the Termination Date,
          and shall be at an annual rate equal to the London  Interbank  Offered
          Rate   ("LIBOR")   for   corresponding   deposits   of  U.S.   Dollars
          ("Eurodollars")  plus 1.25%  ("Eurodollar  Loan Rate").  LIBOR will be
          determined by the principal  London Office of the Bank at the start of
          each  Interest  Period.  Interest  shall  be  paid  at the end of each
          Interest Period or three month intervals, whichever is earlier, and is
          to be  calculated on the basis of the actual number of days elapsed in
          a year of 360 days. Drawdowns for Eurodollar Loans shall require three
          (3) Business Days' (as hereinafter  defined) notice prior to the first
          day of such Interest Period.

          Interest After Maturity

(c)       Interest after maturity on any Loan shall be payable at a rate two
          percent (2%) per annum above the Bank's  Prime Rate,  which rate shall
          be  computed  for  actual  number  of days  elapsed  on the basis of a
          360-day year and shall be adjusted as of the date of each such change,
          but in no event  higher than the maximum  permitted  under  applicable
          law.

          Prepayment

     (a) The Borrower shall have the right (i) at any time and from time to time
to prepay any Prime Rate Loan in full, or in part'  without  penalty and (ii) to
prepay any Eurodollar  Loan in full, or in part. on the last day of the Interest
Period relating to such Loan,  without  penalty.  Any prepayment of a Eurodollar
Loan on a day other than the last day of the  Interest  Period  relating to such
Loan shall be in full,  and upon at least three (3) Business Days' prior written
notice to the Bank, and shall be subject to the penalty  provisions of paragraph
(b) of this Section.  A notice of prepayment  shall specify the prepayment  date
(which shall be a Business Day) and the principal amount to be prepaid, shall be
irrevocable and shall commit the Borrower to prepay the Loan in full on the date
and in the amount stated therein. Each prepayment hereunder shall be accompanied
by accrued pro-rated interest on the principal amount of the Loan to the date of
prepayment.

     (b) The Borrower  shall  reimburse the Bank on demand for any loss incurred
or to be  incurred  by it in the  reemployment  of  the  funds  released  by any
prepayment  of any Loan  permitted  under this  Section.  Such loss shall be the
difference  as  reasonably  determined by the Bank between the cost of obtaining
the funds for such Loan and any lesser  amount which may be realized by the Bank
in reemploying the funds received in prepayment  during the period from the date
of prepayment to the maturity date of the Loan.

                                        2

          Discretionary Loans by the Bank

     The Bank may lend, in its sole  discretion in each  instance,  such amounts
(each a "Loan" and collectively the "Loans") as may be requested by the Borrower
hereunder,  which  Loans  shall  in no  event  exceed  $6,500,000  in  aggregate
principal  amount  outstanding at any time.  Any  Eurodollar  Loan shall be in a
minimum  principal  amount of $500,000 and in increments of $100,000.  Each such
request for a Loan shall be made jointly by the  President  and Chief  Executive
Officer of the Borrower,  both of which are hereby  designated and authorized by
the Borrower to request Loans and agree to the terms thereof  (including without
limitation the Applicable Interest Rate and Maturity Date with respect thereto).
The Borrower  shall give the Bank at least three (3) Business  Days notice prior
to the date of each drawdown and the end of each  Interest  Period (as hereafter
defined) specifying whether the Loan is a Prime Rate Loan or Eurodollar Loan and
the Interest Period applicable  thereto. In the event the Borrower shall fail to
provide  such  notice,  the Loan  shall be  deemed  to be a Prime  Rate Loan and
bearing  interest at the applicable Prime Rate and shall have an Interest Period
of one month.  The principal amount of each Loan shall be paid on the earlier to
occur of the Maturity Date applicable thereto, or the date upon which the entire
unpaid balance of this Note shall otherwise become due and payable.

          Borrowing Sublimit

     Notwithstanding anything in this Note to the contrary, no advances shall be
made  hereunder  and no  letters  of credit  shall be issued by the Bank for the
account of the undersigned  ("Letters of Credit") if, as a result  thereof,  the
aggregate  unpaid  principal  balance  of all  advances  made by the Bank to the
Borrower  hereunder  plus the  aggregate  undrawn  face amount of all Letters of
Credit, the aggregate  unreimbursed  amount of all drafts drawn under Letters of
Credit would exceed Six Million Five Hundred Thousand Dollars ($6,500,000).

          Increased Cost

     If at any time after the date hereof, the Board of Governors of the Federal
Reserve  System or any political  subdivision of the United States of America or
any other government, governmental agency or central bank shall impose or modify
any reserve or capital requirement on or in respect of loans made by or deposits
with the Bank or shall  impose on the Bank or the  Eurodollar  market  any other
conditions  affecting  Eurodollar  Loans,  and the result of the foregoing is to
increase the cost to (or, in the case of  Regulation D, to impose a cost on) the
Bank of making or maintaining  any  Eurodollar  Loans or to reduce the amount of
any sum  receivable by the Bank in respect  thereof,  by an amount deemed by the
Bank to be material,  then,  within 30 days after notice and demand by the Bank,
the Borrower shall pay to the Bank such  additional  amounts as will  compensate
the Bank for such increased cost or reduction; provided, that the Borrower shall
not be obligated to compensate  the Bank for any increased  cost  resulting from
the  application  of  Regulation  D as  required by the  definition  of Adjusted
Eurodollar  Rate, as such term is used in  Regulation D. Any such  obligation by
the Borrower to the Bank shall not be due and owing until the Bank has delivered
written notice to the Borrower. Failure by the Bank to provide such notice shall
not be deemed a waiver of any of its rights hereunder. A certificate of the Bank
claiming  compensation  hereunder and setting forth the additional amounts to be
paid to it hereunder and the method by which such amounts were calculated  shall
be conclusive in the absence of manifest error.

                                        3

          Capital Adequacy

     If the Bank shall have determined that the  applicability of any law, rule,
regulation  or  guideline  adopted  pursuant  to or arising out of the July 1988
report of the Basle Committee on Banking  Regulations and Supervisory  Practices
entitled   "International   Convergence  of  Capital   Measurement  and  Capital
Standards",  or the  adoption  after  the date  hereof of any  other  law,  rule
regulation or guideline regarding capital adequacy,  or any change in any of the
foregoing or in the  interpretation or administration of any of the foregoing by
any governmental  authority,  central bank or comparable agency charged with the
interpretation  or  administration  thereof,  or  compliance by the Bank (or any
lending  office of the Bank) or the Bank's  holding  company with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such  authority,  central bank or comparable  agency,  has or would have the
effect of reducing the rate of return on the Bank's capital or on the capital of
the  Bank's  holding  company,  if any,  .as a  consequence  of its  obligations
hereunder  to a level  below that which the Bank or the Bank's  holding  company
could have achieved but for such  adoption,  change or  compliance  (taking into
consideration  the Bank's  policies  and the  policies  of such  Bank's  holding
company with respect to capital  adequacy) by an amount deemed by the Bank to be
material,  then  from  time to time the  Borrower  shall  pay to the  Bank  such
additional  amount or amounts as will  compensate the Bank or the Bank's holding
company for any such reduction suffered.

          Indemnity

     The Borrower shall indemnify the Bank against any loss or expense which the
Bank may sustain or incur as a  consequence  of the  occurrence  of any Event of
Default or any loss or reasonable  expense  sustained or incurred in liquidating
or  employing  deposits  from third  parties  acquired to effect or maintain any
Eurodollar  Loan or any part  thereof  which the Bank may  sustain or incur as a
consequence of any default in payment of the principal amount of the Loan or any
part thereof or interest accrued thereon. The Bank shall provide to the Borrower
a statement,  supported where applicable by documentary evidence, explaining the
amount of any such loss or expense,  which  statement shall be conclusive in the
absence of manifest error.

          Change In Legality

     (a)  Notwithstanding  anything to the contrary contained  elsewhere in this
Note,  if any change  after the date hereof in any law or  regulation  or in the
interpretation   thereof  by  any  governmental   authority   charged  with  the
administration  thereof  shall  make it  unlawful  (based on the  opinion of any
counsel,  whether  in-house,  special or general,  for the Bank) for the Bank to
make or maintain any  Eurodollar  Loan or to give effect to its  obligations  as
contemplated hereby with respect to any Eurodollar Loan, then, by written notice
to the  Borrower  by the  Bank,  the  Bank  may  require  that  all  outstanding
Eurodollar Loans made hereunder be converted to Prime Loans,  whereupon all such
Eurodollar  Loans  shall be  automatically  converted  to Prime  Loans as of the
effective date of such notice as provided in paragraph (b) below.

     (b) For  purposes  of this  Section,  a notice to the  Borrower by the Bank
pursuant  to  paragraph  (a) above  shall be  effective,  if  lawful  and if any
Eurodollar Loans shall

                                        4

then be  outstanding,  on the  last  day of the then  current  Interest  Period;
otherwise,  such  notice  shall  be  effective  on the  date of  receipt  by the
Borrower.

          Representations

     The  Borrower  represents  and  warrants  that (i) it is  duly,  organized,
validly  existing  and in good  standing  under  the  laws of the  state  of its
incorporation,  (ii) it has full power and authority to execute and perform this
Note,  (iii) that this Note when executed and  delivered in accordance  with its
terms will  constitute  the legal,  valid and binding  obligation of a Borrower,
enforceable  against such  Borrower in  accordance  with its terms,  and (iv) no
contractual restriction prevents the satisfactory  performance or payment of the
Note by the Borrower.

     The Year 2000 date change has not resulted in disruption of the  Borrower's
and its Subsidiaries' computer hardware, software,  databases, systems and other
equipment  containing  embedded  microchips  (including  systems  and  equipment
supplied by others or with which the  Borrower's  or its  Subsidiaries'  systems
interface),  or to the  Borrower's or its  Subsidiaries'  operations or business
systems,  or to the best of the Borrower's and its Subsidiaries'  knowledge,  to
the operations or business systems of the Borrower's  major vendors,  customers,
suppliers and counterparties. Borrower has no reason to believe that liabilities
and  expenditures  related  to the Year  2000  date-change  (including,  without
limitation, costs caused by reprogramming errors, the failure of others' systems
or  equipment,  and the  potential  liability,  if any,  of the  Borrower or its
Subsidiaries  for Year 2000 related costs incurred or disruption  experienced by
others) will result in an Event of Default or a Material Adverse Effect.

                                Events of Default

     If any of the following  events (each,  an "Event of Default")  shall occur
and be continuing:

        (i) the Borrower  shall fail to make payment when due of any principal
        of or interest on any Loan hereunder;  or
        (ii) the Borrower shall fail to perform or observe any other agreement,
        covenant, contained herein; or any  representation  or warranty  made by
        the  Borrower,  contained herein shall prove to have been incorrect in
        any material respect when made or given;  or
        (iii) the Borrower or any  guarantor  shall fail to guarantee the
        obligations under this note pursuant to their respective guaranties
        delivered to the Bank of all of the Borrower's  obligations to the Bank;
        or
        (iv) the  Borrower  shall fail to  provide  financial statements in a
        form acceptable to the Bank at the Bank's request from time  to  time;
        or
        (v)  the  Borrower  shall  default  in  any  other outstanding
        Liabilities (as hereinafter defined) except those disputed in good
        faith by  appropriate  proceedings,  provided  that  adequate reserves
        with respect  thereto  are  maintained  on the books of the Borrower in
        conformity with generally accepted accounting  principals; or
        (vi) the Borrower  shall be adjudged to be insolvent  (however such
        insolvency  may be evidenced),  or  proceedings  are instituted by the
        Borrower under the United States

                                        5

<PAGE>

        Bankruptcy Code or under any bankruptcy,  reorganization  or insolvency
        law or other law for the relief of debtors; or

        (vii)  proceedings are instituted  against the Borrower under the United
        States  Bankruptcy Code or under any  bankruptcy,  reorganization  or
        insolvency  law or other law for the relief of debtors which remain
        undismissed, undischarged  or  unbonded  for a period of 60 days;  or

        (viii)  there shall be a material adverse change, in the Bank's opinion,
         in the financial  condition  of the  Borrower  from  the  date  hereof;

        (ix) complete or partial liquidation or suspension of any business of
        the Borrower; or

        (x) dissolution,  merger, consolidation or reorganization of the
        Borrower;  or

        (xi) attachment,  distraint,  levy, execution or final  judgment against
        the Borrower or any of their  properties;  or

        (xii) any transfer,  assignment,  mortgage, pledge of or creation of a
        security  interest,  other than a  purchase  money  security  interest
        and/or  security  interest  arising in the ordinary course of business
        and/or by  operation  of law, in any  material  asset of the  Borrower
        without the consent of the Bank; and

then, in any such case the Bank may declare the Loan outstanding hereunder to be
forthwith due and payable,  together with accrued  interest,  whereupon the same
will become  forthwith due and payable,  without demand,  presentment,  protest,
notice of dishonor or any other notice or demand whatsoever. Notwithstanding the
foregoing,  upon a default  under  subsection  (vi)  hereunder,  this Note shall
become  immediately  due and payable  without  presentment,  demand,  protest or
notice of any kind, all of which are expressly waived.

     proration,  exceptions or offsets which may be available  from time to time
     to the Bank under such  Regulation D. Statutory  Reserves shall be adjusted
