         FOR VALUE  RECEIVED,  the  undersigned,  Unidigital  Inc.,  a  Delaware
corporation  (the  "Obligor"),  hereby  promises  to pay to the  order  of  Kwik
International Color, Ltd., a New York corporation (the "Holder"),  the principal
sum of Seven  Hundred Fifty  Thousand  Dollars  ($750,000)  payable as set forth
below.  The Obligor also promises to pay to the order of the Holder  interest on
the principal  amount hereof at a rate per annum equal to five and  seven-tenths
percent (5.7%) compounded annually, which interest shall be payable at such time
as the principal is due hereunder.  Interest shall be calculated on the basis of
a year of 365 days and for the number of days actually  elapsed.  Any amounts of
interest and principal not paid when due shall bear interest at the maximum rate
of interest  allowed by  applicable  law. The payments of principal and interest
hereunder  shall be made in coin or  currency  of the  United  States of America
which at the time of payment  shall be legal  tender  therein for the payment of
public and private debts.

         This  Note  shall be  subject  to the  following  additional  terms and
conditions:

         1.    Payments.  Principal  shall be payable in thirty-five  (35) equal
               installments of $20,833.33 and one (1) installment of $20,833.45.
               Each such  payment  shall be made by the Obligor to the Holder on
               the fifteenth  (15th) day of each month,  commencing on April 15,
               1998. In the event that any payment to be made hereunder shall be
               or become due on a Saturday, Sunday or any other day which




               is a legal bank holiday  under the laws of the State of New York,
               such payment shall be or become due on the immediately  preceding
               business day.

         2.    Restrictions on Transferability. This Note may not be transferred
               in any  manner  other  than by will or by the laws of  descent or
               distribution;   provided,  however,  that  the  Holder  shall  be
               permitted to transfer  this Note, in whole or in part, to Richard
               J. Sirota, the sole shareholder of the Holder, Mr. Sirota's wife,
               Mr.  Sirota's  daughter or Walter  Berkower  (each,  a "Permitted
               Transferee").  Prior to  transferring  this Note pursuant to this
               Section 2, the Holder  shall cause the  Permitted  Transferee  to
               agree to be bound by the terms and provisions of this Note.

         3.    No Waiver.  No failure or delay by the Holder in  exercising  any
               right,  power or  privilege  under this Note  shall  operate as a
               waiver thereof nor shall any single or partial  exercise  thereof
               preclude any other or further exercise thereof or the exercise of
               any other  right,  power or  privilege.  The rights and  remedies
               herein  provided  shall be  cumulative  and not  exclusive of any
               rights or remedies  provided by law. No course of dealing between
               the  Obligor  and the  Holder  shall  operate  as a waiver of any
               rights by the Holder.

         4.    Waiver of Presentment and Notice of Dishonor. The Obligor and all
               endorsers,  guarantors and other parties that may be liable under

               and  all  other  demands  and  notices  in  connection  with  the
               delivery, acceptance, performance or enforcement of this Note.

         5.    Place of Payment.  All payments of principal of this Note and the
               interest  due thereon  shall be made at the office of the Holder,
               229 West 28th Street,  New York,  New York  10001-5996 or at such
               other place as the Holder may from time to time designate in
               writing.

         6.    Events of Default.  The entire  unpaid  principal  amount of this
               Note and the  interest  due thereon  shall,  at the option of the
               Holder  exercised  by written  notice to the  Obligor,  forthwith
               become  and be due  and  payable,  without  presentment,  demand,
               protest  or other  notice  of any kind,  all of which are  hereby
               expressly  waived,  if any one or more  of the  following  events
               (herein called "Events of Default")  shall have occurred (for any
               reason  whatsoever and whether such happening  shall be voluntary
               or  involuntary  or come about or be effected by operation of law

                    maturity, or by acceleration or otherwise,  and such default
                    shall have continued for a period of five days;

                                     - 2 -

                         other applicable law or statute of the United States of
                         America or any State, district or territory thereof;

                c)  if a court of competent  jurisdiction  shall enter an order,
                    judgment,  or decree appointing,  without the consent of the
                    Obligor,  a receiver of the whole or any substantial part of
                    Obligor's property, and such order, judgment or decree shall
                    not be  vacated  or set aside or stayed  within 90 days from
                    the date of entry thereof; and

               d)   if, under the  provisions of any other law for the relief or
                    aid of debtors,  any court of competent  jurisdiction  shall

                    not be  terminated or stayed within 90 days from the date of
                    assumption of such custody or control.

               specified  in  Section  6  hereof  shall  have  occurred  and  be
               continuing,  the Holder may  proceed to protect  and  enforce his
               rights either by suit in equity and/or by action at law,  whether
               for  the  specific  performance  of  any  covenant  or  agreement
               contained  in this  Note or in aid of the  exercise  of any power
               granted in this Note,  or the Holder may  proceed to enforce  the
               payment  of all sums due upon this Note or to  enforce  any other
               legal or equitable right of the Holder.

         8.    Severability.  In the event that one or more of the provisions of
               this  Note  shall  for any  reason be held  invalid,  illegal  or
               unenforceable  in any respect,  such  invalidity,  illegality  or
               unenforceability  shall not  affect any other  provision  of this
               Note,  but this  Note  shall  be  construed  as if such  invalid,
               illegal  or  unenforceable  provision  had never  been  contained
               herein.
