$500,000.00                                                     Atlanta, Georgia

                                                                        --

     FOR  VALUE  RECEIVED,   the  undersigned,   COLOR  IMAGE  INC.,  a  Georgia
corporation,  COLOR  IMAGING,  INC.,  a Delaware  corporation,  LOGICAL  IMAGING
SOLUTIONS,  INC.,  a  California  corporation,  and  ALOREX  CORP.,  a New  York
corporation  (collectively,   jointly  and  severally,   "Borrower";   with  all
references herein to "Borrower",  as the context requires or allows, to refer to
each, any and all of the entities constituting Borrower),  jointly and severally
promise to pay to the order of SOUTHTRUST BANK, an Alabama banking  corporation,
successor by conversion to SouthTrust Bank, N.A. ("Bank"), at the office of Bank
in Atlanta,  Georgia, or at such other place as the holder of this Note may from
time to time  designate in writing,  the principal sum of Five Hundred  Thousand
Dollars ($500,000.00),  or so much thereof as may have been advanced to Borrower
from  time to time and not  repaid by  Borrower  pursuant  to the terms  hereof,
together with interest on the unpaid  principal amount of such advances at a per
annum  rate  equal to the Base Rate of Bank as in effect  from time to time plus
one-half  of one  percent  (.5%) so long as the  principal  amount,  or any part
thereof,  is  outstanding.  The  principal  amount of such  advances  shall bear
interest from the date of each such advance.

     Interest provided for herein shall be due and payable monthly commencing on
the 1st day of  September,  2000,  and  continuing on the same day of each month
thereafter  through  and until such time as there  remains  no unpaid  principal
balance on the amounts  advanced to Borrower  hereunder  under that certain Loan
and Security Agreement (as amended,  the "Loan Agreement")  between Borrower and
Bank dated as of May 5, 2000, as amended by Amendment of Loan Documents dated as
of the date hereof. The applicable interest rate shall be determined by Bank and
shall change from time to time as and when the Base Rate of Bank  changes  until
the principal amount is paid in full.

     Principal  and  interest  shall be  payable  in lawful  money of the United
States of America.  Interest on the principal  amount shall be calculated on the
basis of a 360-day year by  multiplying  the  principal  amount by the per annum
rate set forth above,  multiplying  the product  thereof by the actual number of
days elapsed,  and dividing the product so obtained by 360. The term "Base Rate"
means the rate of interest  designated by Bank  peridodically  as its Base Rate.
The Base Rate is not  necessarily the lowest rate charged by Bank. The Base Rate
on the date of this Note is nine and  one-half  percent  (9.5%) per  annum.  The
interest  rate  effective  hereunder on the date of this note is  therefore  ten
percent (10%) per annum.  Time is of the essence with respect to the amounts due
hereunder.

     During the Commitment  Period (as defined in the Loan Agreement),  Borrower
may borrow, repay and reborrow the principal sum of this Note, all in accordance
with the terms of the Loan  Agreement but only in such amounts and to the extent
therein  provided.  On November 30, 2000 or such earlier date as may be provided
in the Loan  Agreement  (the  "Maturity  Date"),  this Note shall mature and all
principal,  interest, and other fees and charges due with respect hereto, if not
previously paid, shall be immediately due and payable.

     Borrower  will pay to Bank a late charge equal to three percent (3%) of any
payment  not  received  by Bank  within  fifteen  (15)  days  after the due date
thereof.  Collection  or  acceptance  by Bank  of such  late  charge  shall  not
constitute a waiver of any remedies of Bank provided herein.


     This Note is the  "Additional  Note"  referred to in and is entitled to the
benefits of the Loan  Agreement  and is secured by the security set forth and/or
referred to in said Loan Agreement. Funds disbursed hereunder shall be disbursed
in accordance with the Loan Agreement.  This Note is unconditionally  guaranteed
by Guaranty Agreements executed by DR. SUE-LING WANG, JUI-CHI (JERRY) WANG, JUI-
HONG (JACK) WANG, JUI-KUNG (ELMER) WANG and KINGS BROTHERS,  LLC. (collectively,
the "Guarantors";  singularly,  a "Guarantor") dated as of May 5, 2000, affirmed
as of the date hereof.

     The principal sum evidenced by this Note,  together with accrued but unpaid
interest, shall be due and payable on the Maturity Date, but in any event at the
option of Bank upon the  occurrence of (1) any failure by Borrower to pay as and
when due any installment of principal or interest due hereunder; (2) any default
or Event of Default under the Loan  Agreement or any other default or failure by
Borrower to observe any covenant, condition or agreement under the terms of this
Note,  the Loan  Agreement,  any of the Loan  Documents  (as defined in the Loan
Agreement),or any other security  documents  heretofore or hereafter executed by
Borrower to secure this Note; (3) the  expiration of the  Commitment  Period (as
defined in the Loan Agreement); (4) the filing by Borrower or any Guarantor of a
voluntary petition in bankruptcy,  the adjudication of Borrower or any Guarantor
as a bankrupt  or  insolvent,  the filing by Borrower  or any  Guarantor  of any
petition or answer seeking or acquiescing  in any  reorganization,  arrangement,
composition, readjustment,  liquidation, dissolution or similar relief under any
present or future federal, state or other statute, law or regulation relating to
bankruptcy,  insolvency  or other  relief  for  debtors,  or  Borrower's  or any
Guarantor's  seeking or consenting to or  acquiescence in the appointment of any
trustee,  receiver or liquidator or the making of any general assignment for the
benefit of creditors or its  admission in writing of its inability to pay its or
his debts  generally  as they become due;  (5) the entry by a court of competent
jurisdiction of an order,  judgment or decree approving a petition filed against
Borrower or any Guarantor seeking any reorganization,  arrangement, composition,
readjustment,  liquidation,  dissolution  or similar relief under any present or
future  federal,   state  or  other  statute,  law  or  regulation  relating  to
bankruptcy,  insolvency,  or other relief for debtors,  which order, judgment or
decree remains  unvacated and unstayed for thirty (30) consecutive days from the
date of entry thereof, or the appointment of any trustee, receiver or liquidator
of Borrower or any Guarantor or of a substantial  part of its or his property or
of any or all of the  rents,  revenues,  issues,  earnings,  profits  or  income
thereof,  (6) the death,  dissolution or  termination of any Guarantor  unless a
substitute  Guarantor  acceptable  to Bank is  obtained  within one  hundred and
twenty  days  (120)  days  of the  death,  dissolution  or  termination  of said
Guarantor; or (7) the occurrence of any material adverse change in the financial
condition or prospects of Borrower or any Guarantor.

     Upon any default,  Borrower  agrees to pay interest to Bank (or any holder)
at the annual rate of two percent  (2%) in excess of the rate  otherwise  herein
provided,  as said  rate  shall  change  from  time to  time,  on the  aggregate
indebtedness  represented by this Note,  including  interest earned to maturity,
from maturity, whether or not resulting from acceleration,  until such aggregate
indebtedness  is paid in full. Bank (or any holder) shall be entitled to recover
all expenses of collecting this Note,  including,  without limitation,  costs of
court and reasonable and actual attorneys' fees.

     The  acceptance  by Bank of any payment or payments due  hereunder,  or any
part of such payment,  after any default  shall not  constitute a waiver of such
default by Bank.

     With  respect  to the  amounts  due under this  Note,  Borrower  waives the
following:

                                       -2-


      1.  All rights of exemption of property from levy or sale under execution
or other process for the collection of debts under the Constitution or laws of
the United States or any state thereof;

      2.  Demand,  presentment,  protest,  notice  of  dishonor,  notice of non-
payment,  suit  against  any  party,  diligence  in  collection,  and all  other
requirements  necessary  to  charge  or  hold  the  undersigned  liable  on  any
obligations hereunder; and

      3.  Any further receipt for or acknowledgment of any collateral now or
hereafter deposited as security for the obligations hereunder.

     Regardless  of any  provision  contained  in this  Note or any of the  Loan
Documents,  in no event shall the  aggregate of all amounts that are  contracted
for, charged or collected  pursuant to the terms of this Note or any of the Loan
Documents, and that are deemed interest under Applicable Law, exceed the Maximum
Rate. No provision of this Note or in any of the Loan  Documents or the exercise
by Bank of any right  hereunder or under any Loan Document or the  prepayment by
Borrower  of  any of  the  Obligations  or  the  occurrence  of any  contingency
whatsoever,  shall entitle Bank to charge or receive,  or to require Borrower to
pay,  interest or any amounts  deemed  interest by Applicable  Law (such amounts
being  referred to herein  collectively  as "Interest") in excess of the Maximum
Rate,  and all  provisions  hereof or in any Loan Document  which may purport to
require  Borrower to pay  Interest  exceeding  the Maximum Rate shall be without
binding  force or effect to the extent only of the excess of Interest  over such
Maximum  Rate.  Any  Interest  charged or received in excess of the Maximum Rate
("Excess"),  shall be conclusively  presumed to be the result of an accident and
bona fide error,  and shall,  to the extent  received by Bank,  at the option of
Bank,  either be applied to reduce the principal  amount of the  Obligations  or
returned  to  Borrower.  The  right to  accelerate  the  maturity  of any of the
Obligations does not include the right to accelerate  unaccrued  interest and no
such  interest will be collected by Bank.  All monies paid to Bank  hereunder or
under any of the Loan  Documents  shall be  subject  to any  rebate of  unearned
interest as and to the extent  required by  Applicable  Law. By the execution of
this Agreement,  Borrower  covenants that (i) the credit or return of any Excess
shall  constitute the  acceptance by Borrower of such Excess,  and (ii) Borrower
shall not seek or pursue any other  remedy,  legal or  equitable,  against Bank,
based in whole or in part  upon  contracting  for,  charging  or  receiving  any
Interest in excess of the Maximum Rate. For the purpose of  determining  whether
or not any Excess has been  contracted  for,  charged or received  by Bank,  all
interest  at any time  contracted  for,  charged or  received  from  Borrower in
connection with this Agreement shall, to the extent permitted by Applicable Law,
be amortized,  prorated, allocated and spread in equal parts throughout the full
term  of the  Obligations.  Borrower  and  Bank  shall,  to the  maximum  extent
permitted under Applicable Law, (i) characterize any non-principal payment as an
expense,  fee or premium  rather than as  Interest  and (ii)  exclude  voluntary
prepayments  and the effects  thereof.  The  provisions of this Section shall be
deemed to be incorporated  into each Loan Document (whether or not any provision
of this Section is referred to therein).

     Borrower and Bank,  as and to the greatest  extent  allowed by law,  hereby
waive any right to trial by jury on any  claim,  counterclaim,  setoff,  demand,
action  or  cause of  action  (a)  arising  out of or in any way  pertaining  or
relating  to this Note,  the Loan  Agreement,  any Loan  Document,  or any other
instrument,  document or agreement executed or delivered in connection with this
Note or (b) in any way connected  with or pertaining or related to or incidental
to any  dealings  of the  parties  hereto  with  respect to this Note,  the Loan
Agreement,  any Loan Document,  or any other  instrument,  document or agreement
executed  or  delivered  in  connection  herewith  or  in  connection  with  the
transactions  related thereto or contemplated  thereby or the exercise of either
party's rights and remedies  thereunder,  in all of the foregoing  cases whether
now existing or hereafter  arising,  and whether  sounding in contract,  tort or
otherwise.  Borrower  and Bank agree that either or both of them may file a copy
of this paragraph with

                                       -3-


any court as written evidence of the knowing,  voluntary and bargained agreement
between the parties  irrevocably to waive trial by jury, and that any dispute or
controversy  whatsoever  between  them  shall  instead  be  tried  in a court of
competent jurisdiction by a judge sitting without a jury.

     Bank shall not by any act, delay,  omission, or otherwise be deemed to have
waived any of its rights or  remedies,  and no waiver of any kind shall be valid
unless in writing and signed by Bank.  All rights and remedies of Bank under the
terms of this  Note  and  under  applicable  statutes  or rules of law  shall be
cumulative and may be exercised  successively or  concurrently.  Borrower agrees
that there are no  defenses,  equities or set off in respect to the  obligations
set forth herein.  The  obligations of Borrower  hereunder shall be binding upon
and enforceable  against Borrower's  successors and assigns.  The obligations of
each person named as Borrower  herein shall be joint and several  obligations of
all such  persons.  This Note shall be governed by, and  construed in accordance
with, the laws of the State of Georgia.  Any provision in this Note which may be
unenforceable  or invalid  under any law shall be  ineffective  to the extent of
such  unenforceability  or invalidity  without  affecting the  enforceability or
validity of any other provision hereof. Any notice required to be given shall be
deemed given if mailed, postage prepaid, to Borrower at the address set forth in
the Loan Agreement.

     This Note is amends and restates Line of Credit  Promissory  Note dated May
5, 2000,  made by Colo  Image,  Inc.  to the order of Bank and is not,  does not
effect and is not intended to be or effect a novation.

     IN WITNESS WHEREOF,  Borrower has executed this instrument under seal as of
the day and year first above written.

                                             BORROWER:
