         NOW,  THEREFORE,  in consideration of these premises and the conditions

         The  indebtedness  initially  evidenced by the  Original  Note shall be

herein, the phrase "Interest Rate" shall mean, as applicable,  the Prime Rate or
the LIBOR Rate.

                                       2


         3. Prime Rate.  Subject to the right of Maker to convert  the  interest
rate as  provided  in  Section  4 below,  the  principal  balance  of this  Note
outstanding  from time to time shall bear  interest at the Prime Rate per annum.
As used  herein,  the phrase  "Prime Rate" means the rate in effect from time to
time as set by the Bank and called its Prime  Rate.  The  effective  date of any
change  in the Prime  Rate  shall  for  purposes  hereof be the date the rate is
changed  by the Bank.  The Bank  shall not be  obligated  to give  notice of any
change in the Prime Rate.

         4. Interest Rate Conversion Option. (a)  Notwithstanding the foregoing,
the Maker shall  provide the Bank with written or oral notice to elect the LIBOR
Rate (as defined below) plus one and one-quarter of one percent (1.25%).

         (b) LIBOR Rate. (i) For purposes hereof,  the phrase "LIBOR Rate" means
the per annum  rate of  interest  at which  U.S.  dollar  deposits  in an amount
comparable to the amount of the relevant  LIBOR Rate loan and for a period equal
to the relevant "Interest Period" (hereinafter defined) are offered generally to

to the Bank not less  than  three  banking  days  prior to the first day of each
respective Interest Period; provided that: (a) each such one, two or three month
period  occurring  after such initial  period shall commence on the day on which
the next preceding  period expires;  (b) the final Interest Period shall be such
that its  expiration  occurs on or before the stated  maturity date of the Note;
and (c) if for any reason the Maker shall fail to select an Interest Period on a
timely  basis,  then it shall be deemed to have  selected  a one month  Interest
Period,  with the exception that if at any time an Interest  Period expires less
than one month  before  the  maturity  date of the Note,  then,  for the  period
commencing on such  expiration  date and ending on the maturity date, such LIBOR
Rate loan shall convert to a loan bearing interest at the Prime Rate.

         (ii) The  Bank's  determination  of LIBOR as  provided  above  shall be
conclusive,  absent manifest error. Furthermore, if the Bank determines, in good
faith (which determination shall be conclusive, absent manifest error), prior to
the  commencement  of any  Interest  Period  that (a) U.S.  dollar  deposits  of
sufficient amount and maturity for funding any LIBOR Rate loan are not available
to the Bank in the London Interbank  Eurodollar market in the ordinary course of
business,  or (b) by reason of  circumstances  affecting  the  London  Interbank
Eurodollar  market,  adequate and fair means do not exist for  ascertaining  the
rate of interest to be  applicable  to the  relevant  LIBOR Rate loan,  the Bank
shall  promptly  notify the Maker and such  LIBOR Rate loan shall  automatically
convert on the last day of its  then-current  Interest  Period to a loan bearing
interest at the Prime Rate minus one and four-tenths of one percent (-1.40%). If

applicable law, treaty,  rule,  regulation or guideline or in the interpretation
or administration thereof by any governmental  regulation or any central bank or
other fiscal,  monetary or other authority having  jurisdiction over the Bank or
its lending office (a "Regulatory Change"),  shall, in the opinion of counsel to
the Bank, makes it unlawful for the Bank to make or maintain any LIBOR Rate loan
evidenced hereby or (b) for any other reason the LIBOR Rate loan funding becomes
unavailable to the Bank,  then the Bank shall promptly notify the Maker and such
LIBOR Rate loan shall automatically  convert on the last day of its then-current
Interest  Period to a loan  bearing  interest  at the Prime  Rate  minus one and
four-tenths of one percent (-1.40%).

                                       3


         (iii) If, for any reason, any LIBOR Rate loan is paid prior to the last
banking day of its then-current  Interest Period,  the Maker agrees to indemnify
the Bank  against  any loss  (including  any loss on  redeployment  of the funds
repaid), cost or expense incurred by the Bank as a result of such prepayment. Of
any Regulatory Change (whether or not having the force of law) shall (a) impose,
modify or deem  applicable any assessment,  reserve,  special deposit or similar
requirement  against  assets  held by, or  deposits  in or for the account of or
loans by, or any other  acquisition of funds or disbursements  by, the Bank; (b)
subject the Bank or any LIBOR Rate loan to any tax, duty,  charge,  stamp tax or
fee or change  the basis of  taxation  of payment  to the Bank of  principal  or
interest  due from the Maker to the Bank  hereunder  (other than a change of the
taxation of the  overall net inform of the Bank);  or (c) impose on the Bank any
other  condition  regarding such LIBOR Rate loan or the Bank's funding  thereof,
and the Bank shall determine (which  determination  shall be conclusive,  absent
manifest  error) that the result of the foregoing is to increase the cost to the
Bank of making or  maintaining  such  LIBOR Rate loan or to reduce the amount of
principal or interest  received by the Bank hereunder,  then the Maker shall pay
the Bank, on demand,  such  additional  amounts as the Bank shall,  from time to
time,  determine are  sufficient  to compensate  and indemnify the Bank for such
increased cost or reduced amount.

If Maker shall fail to indicate an  interest  rate option as  aforesaid  for any
loan  advance,  such advance  shall be deemed to bear interest at the Prime Rate
option as set forth above.

         5. Payments. This Note shall be repaid as follows:

         (i)  Interest on the portion of the unpaid  principal  balance  bearing
interest at the Prime Rate shall be payable quarterly in arrears,  commencing on
June 1, 2001 and continuing quarterly thereafter.

         (ii)  Interest  on each  LIBOR  Rate loan  shall be payable on the last
banking day of each Interest Period with respect thereto.

         (iii) A final  payment  equal to the  total  principal  then  remaining
unpaid, plus accrued interest,  shall be paid on November 1, 2001. Any amount of
principal  or  interest  which is not  paid  when  due,  whether  at the  stated
maturity, by acceleration or otherwise, shall bear interest payable on demand at
an interest  rate per annum equal at all times to the then  applicable  Interest
Rate plus two percent (2%).

         6. Principal Prepayments. Prepayments of Prime Rate loans are permitted
at any  time,  together  with  all  interest  accrued  thereon  to the  date  of
prepayment, without premium or penalty.

the  loan  commitment  evidenced  by this  Note,  which  fee  shall  be  payable
quarterly, in arrears, beginning on June 1, 2001.

         8. Indebtedness Prohibited. Maker shall not, directly or indirectly, be
liable for,  create,  assume,  incur or permit to exist any senior  indebtedness
whether as primary obligor, guarantor, surety or otherwise,  including,  without
limitation,  purchase money indebtedness except (a) indebtedness in favor of the
Bank, and (b)  indebtedness  for liens for taxes or other  governmental  charges
incurred in the ordinary course of business.

         (iii) If, for any reason, any LIBOR Rate loan is paid prior to the last
banking day of its then-current  Interest Period,  the Maker agrees to indemnify
the Bank  against  any loss  (including  any loss on  redeployment  of the funds
repaid), cost or expense incurred by the Bank as a result of such prepayment. Of
any Regulatory Change (whether or not having the force of law) shall (a) impose,
modify or deem  applicable any assessment,  reserve,  special deposit or similar
requirement  against  assets  held by, or  deposits  in or for the account of or
loans by, or any other  acquisition of funds or disbursements  by, the Bank; (b)
subject the Bank or any LIBOR Rate loan to any tax, duty,  charge,  stamp tax or
fee or change  the basis of  taxation  of payment  to the Bank of  principal  or
interest  due from the Maker to the Bank  hereunder  (other than a change of the
taxation of the  overall net inform of the Bank);  or (c) impose on the Bank any
other  condition  regarding such LIBOR Rate loan or the Bank's funding  thereof,
and the Bank shall determine (which  determination  shall be conclusive,  absent
manifest  error) that the result of the foregoing is to increase the cost to the
Bank of making or  maintaining  such  LIBOR Rate loan or to reduce the amount of
principal or interest  received by the Bank hereunder,  then the Maker shall pay
the Bank, on demand,  such  additional  amounts as the Bank shall,  from time to
time,  determine are  sufficient  to compensate  and indemnify the Bank for such
increased cost or reduced amount.

If Maker shall fail to indicate an  interest  rate option as  aforesaid  for any
loan  advance,  such advance  shall be deemed to bear interest at the Prime Rate
option as set forth above.

         5. Payments. This Note shall be repaid as follows:

         (i)  Interest on the portion of the unpaid  principal  balance  bearing
interest at the Prime Rate shall be payable quarterly in arrears,  commencing on
February 1, 2002 and continuing quarterly thereafter.

         (ii)  Interest  on each  LIBOR  Rate loan  shall be payable on the last
banking day of each Interest Period with respect thereto.

         (iii) A final  payment  equal to the  total  principal  then  remaining
unpaid, plus accrued interest,  shall be paid on November 1, 2002. Any amount of
principal  or  interest  which is not  paid  when  due,  whether  at the  stated
maturity, by acceleration or otherwise, shall bear interest payable on demand at
an interest  rate per annum equal at all times to the then  applicable  Interest
Rate plus two percent (2%).

         6. Principal Prepayments. Prepayments of Prime Rate loans are permitted
at any  time,  together  with  all  interest  accrued  thereon  to the  date  of
prepayment, without premium or penalty.

quarterly, in arrears, beginning on December 1, 2001.

         8. Indebtedness Prohibited. Maker shall not, directly or indirectly, be
liable for,  create,  assume,  incur or permit to exist any senior  indebtedness
whether as primary obligor, guarantor, surety or otherwise,  including,  without
limitation,  purchase money indebtedness except (a) indebtedness in favor of the
Bank,  (b)  indebtedness  for  liens  for  taxes or other  governmental  charges
incurred  in the  ordinary  course  of  business;  and (c) debt  created  by the
