                                   (Sheet Metal)

$520,745.96,  subject  to  adjustment                             June  1,  2001

     FOR VALUE RECEIVED, the undersigned ALTON DIVERSIFIED TECHNOLOGIES, INC., a
California  corporation  ("Alton"), hereby promises to pay to the order of I-PAC
PRECISION  MACHINING,  INC., a California corporation (including its successors,
transferees and assigns, "Precision" or "Payee"), c/o Celtic Capital Corporation
("Celtic") at its office at 2951 28th Street, Suite 2030, Santa Monica, CA 90405
or at such other place as Payee may designate in writing, in lawful money of the
United  States  of  America  and  in  immediately available funds, the principal
amount  of  Five  Hundred  Twenty  Thousand  Seven Hundred Forty-Five and 96/100
Dollars($520,745.96)  (which  represents  the  agreed  gross  inventory value of
Precision's  inventory  whether  or not such inventory is useable as of the date
hereof  and  pursuant  to  the  attached Schedule 1), which amount is subject to
adjustment  pursuant  to  the  third  paragraph  of this Note (the "Loan"), with
interest  thereon from the date hereof until maturity, at a fluctuating rate per
annum  equal  at  all  times  to  the  sum of (a) the rate of interest per annum
announced  by  Wells  Fargo  Bank,  N.A.  at  its  head office in San Francisco,
California  from  time  to time as its "prime rate" or "reference rate" plus (b)
one  and  one-quarter  percent  (1.25%)  per  annum.

Interest  on  the  Loan shall be payable in arrears on the first business day of
each  calendar  month, commencing on September 4, 2001, and on the date on which
the  Loan  is  paid  in  full.  Principal  of  the  Loan  shall be payable in 12
installments  as  follows:  11  installments  of  $45,395.00 each, commencing on
January  1,  2002  and  ending  on  November 1, 2002, and a final installment of
$43,400.96  (plus  accrued  but  unpaid  interest)  payable on December 1, 2002.

If  and  so  long as the principal amount of the Loan does not exceed the amount
first  set  forth  above  (after adjusting for any repayments of principal), the
principal  amount  of  the  Loan  shall  be  adjusted  as  follows:

(1)     Interest  Adjustment.  On  September 4, 2001 the principal amount of the
Loan shall be increased by the amount equal to the amount of interest accrued on
the  Loan from and including the date of this Note to but excluding September 4,
2001.  Such  increase  shall  be  reflected  in  Addendum  No.  1  to this Note.
Addendum  No. 1 shall also set forth the new principal amortization schedule for
the  remaining  term  of  this  Loan.

(2)     Interim  Adjustment.  On  December 4, 2001, Alton and Precision (even if
Precision  has  assigned  this  Note  to Celtic) shall, acting in good faith and
using  their  reasonable  business  judgment,  adjust  and restate the remaining
balance  of the principal amount of the Loan to reflect the value as of the date
hereof  of  "Useable  Inventory"  remaining  from  the  inventory purchased from
Precision  as of the date hereof.  "Useable Inventory" for purposes of this Note
will  be  inventory purchased from Precision as of the date hereof which (i) was
actually  consumed  through  December 4, 2001, or (ii) is expected to be used in
products  for  current  customers  based on existing orders or customer forecast
requirements.  If  Useable  Inventory  at  December  4, 2001 is determined to be
greater  than  the agreed value of Useable Inventory as reflected on Schedule 1,
the principal amount of this Loan may be adjusted upward but not higher than the
initial  principal  amount  of  this  Note.  To  the  extent remaining inventory
purchased  from  Precision is not determined to be Useable Inventory, it will be
revalued  downward to 5% of value used to determine the gross inventory value on
Schedule  1  hereof and the principal balance of this Note adjusted accordingly.
The  sum  of  the  value  of Useable Inventory at December 4, 2001 and 5% of the
value  of  the  unuseable  inventory will be the interim principal amount of the
Loan  and  the  Note will be adjusted and restated accordingly.  A new principal
amortization  schedule  (taking  into  account  prior  payments of principal and
interest)  will  be  determined  and  recorded  on  Addendum No. 2 to this Note,
provided  that  (i)  the total amount of principal to be paid on this Loan shall
never  exceed  the initial principal amount of this Note,  (ii) it is understood
and  agreed  that  certain  payments  that  may  originally have been applied to
interest  may  be  reapplied  to  principal,  and  (iii)  in  no  case will this
adjustment  cause  the  remaining  principal  to  fall  below  what  Alton  has
cumulatively  paid  to  the  date  of  the  adjustment.

(3)     Final  Adjustment.  On  June  4,  2002,  Alton  and  Precision  (even if
Precision  has  assigned  this  Note  to Celtic) shall, acting in good faith and
using  their  reasonable  business  judgment,  adjust  and restate the remaining
balance  of the principal amount of the Note to reflect the value as of the date
hereof of "Useable Inventory" remaining from that purchased from Precision as of
the  date  hereof, which (i) was actually consumed through June 4, 2001, or (ii)
is  expected  to  be  used  in  products for current customers based on existing
orders.  To  the  extent  remaining  inventory  purchased  from Precision is not
determined  to be Useable Inventory, it will be revalued downward to 5% of value
used  to  determine  the gross inventory value on Schedule 1 hereof.  The sum of
the  value of Useable Inventory and 5% of the value the unuseable inventory will
be  the  final  principal  amount  of  the  Loan.  A  new principal amortization
schedule  (taking into account prior payments of principal and interest) will be
determined  and  recorded  on Addendum No. 3 to this Note, provided that (i) the
total amount of principal to be paid on this Loan shall never exceed the initial
principal  amount  of  this  Note, (ii) it is understood and agreed that certain
payments  that  may originally have been applied to interest may be reapplied to
principal  and  (iii)  in  no  case  will  this  adjustment  cause the remaining
principal  to  fall  below  what  Alton has cumulatively paid to the date of the
adjustment.

Any amount of principal or interest on this Note that is not paid when due shall
bear interest, payable on demand, until such amount is paid in full, at the rate
of  12%  per  annum.

This  Note  is entered into pursuant to the Asset Purchase Agreement dated as of
June  1,  2001  among  I-PAC  Manufacturing,  Inc.,  a  California  corporation
("Electronics"), Precision, Alton and National Manufacturing Technologies, Inc.,
a  California  corporation, and evidences part of the purchase-price obligations
thereunder.

If an Event of Default (as defined in the Security Agreement dated as of June 1,
2001  made  by  Alton  in  favor  of  Electronics  and  Precision) occurs and is
continuing,  Payee  may,  by  notice  to  Alton,  declare the Loan, all interest
thereon  and  all  other amounts payable under this Note to be forthwith due and
payable,  whereupon the Loan, all such interest and all such other amounts shall
become and be forthwith due and payable, without presentment, demand, protest or
further  notice  of any kind, all of which are hereby expressly waived by Alton.
No  failure to exercise, or delay in exercising, any right hereunder on the part
of  Payee  shall  operate  as  a  waiver  of  any  such  rights.

Alton and Payee intend that the Loan be in strict compliance with any applicable
usury law.  In furtherance thereof, Alton and Payee agree that none of the terms
of this Note shall ever be construed to create a contract to pay interest or its
equivalent  at  a  rate  in  excess  of  the  maximum interest rate permitted by
applicable  law.  Accordingly,  if  a court determines that the usury law of any
jurisdiction  applies to the Loan:  (1) neither Alton nor any endorsers or other
parties  now or hereafter becoming liable for payment of this Note shall ever be
required  to  pay  interest  on  this  Note  at  a rate in excess of the maximum
interest  that  may be lawfully charged under applicable law, and the provisions
of  this  paragraph shall control over all other provisions of this Note; (2) if
the  maturity  of this Note is accelerated for any reason or if the principal of
this  Note  is  paid before the end of the term of this Note, and in either case
the  interest  received  for the actual period of existence of the Loan would be
unlawful,  Payee  will, at its option, either refund to Alton the amount of such
excess or credit the amount of such excess against the principal balance of this
Note  then  outstanding;  and (3) in the event that Payee collects money that is
deemed to constitute interest that would increase the effective interest rate on
this Note to a rate in excess of that permitted by applicable law, all such sums
deemed  to  constitute  interest  in  excess  of the legal rate shall, upon such
determination,  at  Payee's option, be immediately returned to Alton or credited
against  the  principal  balance  of  this  Note  then  outstanding.

Alton  will  reimburse  Payee  for  all  reasonable  attorneys'  fees, costs and
expenses  incurred by Payee in connection with the enforcement of Payee's rights
under  this  Note,  including,  without  limitation, for (1) trial and appellate
proceedings,  out-of-court  negotiations,  workouts  and  settlements  and  (2)
enforcement  of  Payee's  rights  under any state or federal statute, including,
without  limitation,  in  protecting  Payee's  security  and  in  bankruptcy and
insolvency  proceedings.

THIS  NOTE  SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH,
THE  LAWS  OF  THE  STATE  OF  CALIFORNIA.
