NEW YORK, NEW YORK

                  ACL   SEMICONDUCTORS   INC.,  a  Delaware   corporation   (the
"COMPANY"),  for value received,  hereby promises to pay to PROFESSIONAL TRADERS
FUND,  LLC, with an address at 990 Stewart  Avenue,  Suite 420, Garden City, New

HUNDRED FIFTY THOUSAND  UNITED STATES DOLLARS  (US$250,000) on the Maturity Date
(as defined below),  and to pay interest on the unpaid principal  balance hereof
at the rate  (calculated  on the basis of a 360-day  year  consisting  of twelve
30-day months) of 12% per annum from the date hereof (the "Issuance Date") until
the Maturity  Date,  subject to increase as provided  herein in certain  events.
Accrued  interest  on the  unpaid  principal  balance  hereof  shall be  payable
quarterly in arrears and on the Maturity Date or upon the earlier  conversion or
repayment  of this Note,  in each case in cash or shares of common  stock of the
Company (the "COMMON STOCK") at the option of the Holder,  as described  herein.
In no event shall any  interest  to be paid  hereunder  exceed the maximum  rate
permitted  by law. In any such event,  this Note shall  automatically  be deemed
amended to permit  interest  charges at an amount equal to, but no greater than,
the maximum rate permitted by law.

         2. PAYMENTS.

         (a)      Subject to Section 8 hereof,  principal  of this Note shall be
due and  payable in full on the  Maturity  Date.  The  "MATURITY  DATE" shall be
December 31, 2004.

         (b)      (i)      Subject  to  Section  8  hereof  and the  immediately
following sentence, interest on this Note shall accrue from the date of issuance
hereof to, but  excluding,  the Maturity  Date, at the rate of 12% per annum and
shall be payable in arrears on March 31, 2004, June 31, 2004, September 31, 2004
(each an "INTEREST  PAYMENT DATE"),  and on the Maturity Date. In the event that
there shall be an Event of Default (as hereinafter defined),  from and after the
date of such Event of Default, interest on this Note shall accrue at the rate of
15% per annum.

                  (ii)     Subject to Section 8 hereof, upon written notice (the
"SHARE PAYMENT NOTICE") given by the Holder to the Company at least 30 days, but
not more than 60 days,  prior to any Interest Payment Date or the Maturity Date,
as applicable,  the interest on this Note payable on such Interest  Payment Date
or on the Maturity Date shall be paid by the Company on such date in the form of
shares of Common Stock.  In the event that the Share  Payment  Notice shall have
been timely  given with  respect to any  Interest  Payment  Date or the Maturity
Date, as applicable, the number of shares of Common Stock issuable to the Holder
in lieu of the cash  payment of  interest  on this Note due and  payable on such
date shall equal the  quotient of (A) divided by (B),  where (A) equals the cash
payment of interest on this Note due and payable on such  Interest  Payment Date
or the Maturity Date, as applicable,  and where (B) equals the Conversion  Price
(as hereinafter defined).

         (c)      If any Interest  Payment Date or the Maturity  Date falls on a
day that is not a Business  Day (as  defined  below),  the  payment  due on such
Interest Payment Date, or the Maturity Date, as applicable,  will be made on the
next  succeeding  Business Day with the same force and effect as if made on such
Interest  Payment Date or the Maturity Date, as the case may be.  "BUSINESS DAY"
means  any day  which  is not a  Saturday  or  Sunday  and is not a day on which
banking  institutions are generally authorized or obligated to close in the City
of New York, New York.

         (d)      The Company may, at its option  during the period  terminating
90 days from the date of  issuance  of this Note,  prepay all or any part of the
principal of this Note,  subject to the payment of the premium described in this
paragraph  (d).  All  payments  on this Note shall be  applied  first to accrued
interest hereon and the balance to the payment of principal hereof.  The penalty
for  prepayment  shall equal the product of (I)  multiplied  by (II),  where (I)
equals the sum of the  principal  amount of, and interest on, this Note to be so
prepaid, and where (II) equals 0.50.

         (e)      Payments of principal  and interest on this Note shall be made
by check sent to the Holder's  address set forth above or to such other  address
as the Holder may designate for such purpose from time to time by written notice
to the Company,  in such coin or currency of the United  States of America as at
the time of payment  shall be legal tender for the payment of public and private
debts.

         (f)      The obligations to make the payments provided for in this Note
are  absolute  and  unconditional  and  not  subject  to any  defense,  set-off,

hereby  expressly   waives  demand  and  presentment  for  payment,   notice  of
non-payment,  notice of dishonor,  protest, notice of protest, bringing of suit,
and diligence in taking any action to collect any amount  called for  hereunder,
and shall be directly and primarily liable for the payment of all sums owing and

present  in  all  material  respects  the  financial  position  and  results  of
operations of the Company and its subsidiaries, all in accordance with generally
accepted  accounting  principles   consistently  applied  (other  than  footnote

<PAGE>

Default Penalty (as hereinafter defined), shall automatically become immediately
due and payable without  presentment,  demand,  protest, or other formalities of
any kind,  all of which are hereby  expressly  waived by the  Company.  Upon the
occurrence  of an Event of  Default  referred  to in  Section  5(a) or (b),  the
Holder,  by notice in  writing  given to the  Company,  may  declare  the entire
principal  amount then  outstanding of, and the accrued  interest on, this Note,
together with the Default Penalty, to be due and payable  immediately,  and upon
any such  declaration the same shall become and be due and payable  immediately,

which are expressly  waived by the Company.  Upon the  occurrence of an Event of
Default other than one referred to in Sections  5(a), (b) or (f), the Holders of
not less than 50% in principal amount of then  outstanding  Notes (excluding any
Notes held by or for the account of the Company or any affiliate of the Company)
may declare the principal  amount then  outstanding of, and the accrued interest
on,  the  Notes,  together  with  the  Default  Penalty,  to be due and  payable
immediately,  and upon such  declaration  the same shall  become due and payable

kind,  all of which are  expressly  waived by the Company.  For purposes of this
Note, the term "DEFAULT  PENALTY" shall mean the product of (I) and (II),  where
(I) equals the sum of the principal  amount then outstanding of, and the accrued
interest on, this Note through the date of such Event of Default,  and where (B)
equals 0.30. At the option of the Holder by written  notice to the Company,  the
payment of the principal  amount then  outstanding of, and the accrued  interest
on,  this Note,  together  with the  Default  Penalty,  may be paid in shares of
Common Stock at the Conversion Price.

         (b)      The Holder may institute such actions or proceedings in law or
equity as it shall  deem  expedient  for the  protection  of its  rights and may
prosecute  and enforce  its claims  against  all assets of the  Company,  and in
connection with any such action or proceeding  shall be entitled to receive from
the Company payment of the principal  amount of this Note plus accrued  interest
to the date of  payment  plus  reasonable  expenses  of  collection,  including,
without limitation, reasonable attorneys' fees and expenses.

         7.       TRANSFER.

         (a)      Any Notes  issued  upon the  transfer  of this  Note  shall be
numbered  and shall be  registered  in a Note  Register as they are issued.  The
Company shall be entitled to treat the registered holder of any Note on the Note
Register as the owner in fact thereof for all purposes and shall not be bound to
recognize  any  equitable or other claim to or interest in such Note on the part
of any other person, and shall not be liable for any registration or transfer of
Notes which are registered or to be registered in the name of a fiduciary or the
nominee of a fiduciary unless made with the actual knowledge that a fiduciary or
nominee is  committing  a breach of trust in  requesting  such  registration  or
transfer,  or with the  knowledge of such facts that its  participation  therein
amounts to bad faith. Subject to applicable law, this Note shall be transferable
only on the books of the Company  upon  delivery  thereof  duly  endorsed by the
Holder or by his duly authorized  attorney or representative,  or accompanied by
proper  evidence of  succession,  assignment,  or authority to transfer.  In all
cases of transfer by an attorney,  executor,  administrator,  guardian, or other
legal representative,  duly authenticated evidence of his or its

                                     - 6 -
<PAGE>

authority  shall be produced.  Upon any  registration  of transfer,  the Company
shall deliver a new Note or Notes to the person entitled thereto.  This Note may
be exchanged,  at the option of the Holder  thereof,  for another Note, or other
Notes  of  different  denominations,  of  like  tenor  and  representing  in the
aggregate a like  principal  amount,  upon  surrender to the Company or its duly
authorized  agent.  Notwithstanding  the  foregoing,  the Company  shall have no
obligation  to cause Notes to be  transferred  on its books to any person if, in
the opinion of counsel to the Company,  such  transfer  does not comply with the
provisions of the Securities Act and the rules and regulations thereunder.

         (b)      The  Holder  acknowledges  that  he has  been  advised  by the
Company that this Note has not been  registered  under the Securities  Act, that
this Note is being issued on the basis of the  statutory  exemption  provided by
Section  4(2)  of the Act or  Regulation  D  promulgated  thereunder,  or  both,
relating to  transactions  by an issuer not involving any public  offering,  and
that the Company's  reliance  thereon is based in part upon the  representations
made by the original  Holder in the  original  Holder's  Subscription  Agreement
executed and delivered in accordance with the terms of the Offering.  The Holder
acknowledges  that he has been  informed  by the  Company  of,  or is  otherwise
familiar with, the nature of the  limitations  imposed by the Securities Act and
the  rules  and  regulations  thereunder  on  the  transfer  of  securities.  In
particular,  the Holder agrees that no sale, assignment or transfer of this Note
shall be valid or  effective,  and the Company shall not be required to give any
effect  to  any  such  sale,  assignment  or  transfer,  unless  (i)  the  sale,
assignment,  or transfer of this Note is registered under the Securities Act, it
being  understood  that this Note is not currently  registered for sale and that
the Company has no  obligation  or intention  to so register the Notes,  or (ii)
this  Note  is  sold,  assigned,  or  transferred  in  accordance  with  all the
requirements and limitations of Rule 144 under the Act, it being understood that
Rule 144 is not available at the time of the original  issuance of this Note for
the sale of this  Note and that  there can be no  assurance  that Rule 144 sales
will be available at any  subsequent  time, or (iii) such sale,  assignment,  or
transfer is otherwise exempt from registration under the Securities Act.

         8.       CONVERSION.

         (a)      (i)      Subject to Section 2(b) hereof,  the Holder may elect
to receive the  principal  amount of this Note due and  payable on the  Maturity
Date, or any payment of interest thereon due on any Interest Payment Date or the
Maturity Date, in each case in shares of Common Stock

                  (ii)     At any time on or after the  Issue  Date and prior to
the time  this  Note is paid in full in  accordance  with its  terms  (including
without  limitation after the Maturity Date and after the occurrence of an Event
of  Default,  as defined  above),  the Holder of this Note is  entitled,  at its
option,  subject to the following  provisions of this Section 8, to convert this
Note at any time into shares of Common Stock at the Conversion Price (as defined
below).

         (b)      The number of shares of Common Stock to be delivered upon such
conversion  shall equal the quotient of (A) divided by (B), where (A) equals the
principal  amount of, and

                                     - 7 -

accrued but unpaid  interest on, this Note,  and where (B) equals the Conversion
Price.  For purposes of this Note,  the term  "CONVERSION  PRICE" shall mean the
product of (X) multiplied by (Y), where (X) equals the average closing price for
the three trading days  immediately  prior to such Interest  Payment Date or the
Maturity  Date, as applicable,  in the case of conversions  referenced in clause
(a)(i) of this  Section 8, or the three  trading days  immediately  prior to the
date of the relevant Notice of Conversion (as  hereinafter  defined) in the case
of  conversions  referenced  in clause  (a)(ii) of this Section 8, and where (Y)
equals  0.40,  provided,  however,  in no event  shall the  Conversion  Price be
greater than $1.00.

         (c)      Conversion   shall  be  effectuated  by  faxing  a  Notice  of
Conversion  to the  Company  as  provided  in  this  paragraph.  The  Notice  of
Conversion  shall be executed by the Holder of this Note and shall evidence such
Holder's  intention to convert this  Debenture or a specified  portion hereof in
the form annexed  hereto as Exhibit A. If paid in Common  Stock as  contemplated
hereby, accrued and unpaid interest from the Issue Date to the relevant Interest
Payment Date shall be paid in Common Stock at the Conversion Price applicable as
of such Interest  Payment  Date.  No fractional  shares of Common Stock or scrip
representing fractions of shares will be issued on conversion, but the number of
shares  issuable shall be rounded to the nearest whole share.  The date on which
notice of conversion is given (the "CONVERSION  DATE") shall be deemed to be the
date on which the Holder  faxes or  otherwise  delivers  the  conversion  notice
("NOTICE OF CONVERSION") to the Company so that it is received by the Company on
or before such specified date,  provided that, if such conversion  would convert
the entire  remaining  principal of this Debenture,  the Holder shall deliver to
the Company the original Notes being  converted no later than three (3) business
days  thereafter.  Facsimile  delivery  of the  Notice  of  Conversion  shall be
accepted  by the Company at  facsimile  number:  #852  27589061,  Attention  Mr.
Chung-Lun  Yang.  Certificates  representing  shares of Common Stock upon issued
conversion in whole or in part of the Notes ("CONVERSION CERTIFICATES") shall be
delivered  to the Holder at the address  specified  in the Notice of  Conversion
(which may be the Holder's address set forth herein or a different address), via
express courier, by electronic transfer or otherwise,  within three (3) business
days (such third business day, the "DELIVERY  DATE") after the date on which the
Notice of  Conversion  is  delivered  to the  Company  as  contemplated  in this
paragraph  (c),  and, if interest is paid in the form of shares of Common Stock,
the Interest  Payment  Date.  The Holder shall be deemed to be the holder of the
shares  issuable  thereto in accordance with the provisions of this Section 8(c)
on the Conversion Date.
