and among  Unidigital Inc., a Delaware  corporation (the "Company"),  William E.
Dye ("Dye"),  and Richard J. Sirota  ("Sirota" and,  collectively  with Dye, the
"Stockholders").

                              W I T N E S S E T H :

     WHEREAS,  the Company is  authorized to issue  10,000,000  shares of common
stock, $0.01 par value (the "Common Stock"); and

     WHEREAS,  Dye, on the date hereof, has voting control over 1,051,421 shares
of the Common Stock; and

     WHEREAS,  the Company and Sirota are parties to that certain Asset Purchase
Agreement (the "Asset Purchase Agreement") dated March 25, 1998 by and among the
Company,  Unison (NY), Inc., a Delaware corporation and wholly-owned  subsidiary
of  the  Company  ("Unison"),   Kwik  International  Color,  Ltd.,  a  New  York
corporation  ("Kwik"),  and  Sirota,  pursuant  to which  Sirota has been issued
649,841 shares of the Common Stock (the "Sirota Shares"); and

     WHEREAS,  the parties deem it in the best  interests of each of the parties
to restrict the transfer of the  Restricted  Shares (as defined below) as herein
provided.

     NOW,  THEREFORE,  in consideration of the promises and the mutual covenants
contained herein, the Parties hereto hereby agree as follows:

          SECTION 1. General Restrictions on Transfer of the Restricted Shares.

          (a)  During the term of this  Agreement,  none of the shares of Common
Stock  owned  on the date  hereof  or  thereafter  acquired  by any  Stockholder
(collectively,  the "Restricted Shares") may be transferred,  assigned, pledged,
encumbered or otherwise hypothecated except in accordance with the provisions of
this Agreement.

          (b) Any  attempted  transfer of the  Restricted  Shares  other than in
accordance with this Agreement (other than an involuntary  transfer by operation
of law) shall be null and void and the Company  shall  refuse to  recognize  any
such  transfer  and  shall  not  reflect  on its  records  any  change in record
ownership of the Restricted Shares pursuant to any such transfer.

          (c)  Notwithstanding  anything  contained herein to the contrary,  but
subject to Section 5 hereof,  it is  understood  and agreed that (i) each of the
Stockholders may transfer any or all of the Restricted Shares beneficially owned
by him to his immediate family (as defined below), or to trusts  established for
the benefit of such  immediate  family,  provided that in  connection  with such
transfer,  the transferee grants to such transferor an irrevocable proxy coupled
with an interest to vote all of the Restricted  Shares so transferred,  and (ii)
in the case of Sirota,  the Sirota Shares may be transferred to Sirota's  former
business partner, Walter Berkower. Such transferees shall be




referred to herein as  "Permitted  Transferees."  For  purposes of this  Section
1(c), "immediate family" shall mean any child,  stepchild,  grandchild,  parent,
stepparent,   grandparent,   spouse,  sibling,   mother-in-law,   father-in-law,
daughter-in-law,  brother-in-law,  or sister-in-law,  and shall include adoptive
relationships.

          SECTION 2. Right of First Refusal.

          (a) Subject to Section  2(f)  hereof,  whenever and as often as any of
the Stockholders shall desire to sell any of the Restricted Shares pursuant to a
bona fide offer for the purchase thereof in a private transaction,  such selling
Stockholder (the "Selling  Stockholder") shall give notice (the "Notice") to the
Company in writing to such effect,  enclosing a copy of such bona fide offer (it
being  agreed  that the  Selling  Stockholder  shall  cause any such offer to be
reduced  to  writing)  and  specifying  the  number  of  shares  of the  Selling
Stockholder's  Restricted Shares which such Selling  Stockholder desires to sell
(the  "Shares"),  the  name  of the  person  or  persons  to whom  such  Selling
Stockholder  desires to make such sale and the dollar value of the consideration
which has been offered in connection therewith.  Upon receipt of the Notice, the
Company  shall have the first right and option to purchase all but not less than
all of the Shares,  for cash at a purchase  price  equal to the dollar  value of
such   consideration   (in  the  event  such   consideration   includes  noncash
consideration,  subject to Section 2(g) hereof, the dollar value of such noncash
consideration shall be determined by the Company's Board of Directors,  provided
that if such Selling Stockholder is a member of the Board of Directors, he shall
not  participate in such  determination),  exercisable  for a period of ten (10)
days from the date of receipt of the  Notice.  Failure of the Company to respond
to the Notice  within the ten (10) day period  shall be deemed to  constitute  a
notification  to the  Selling  Stockholder  of  the  Company's  decision  not to
exercise  the first right and option to purchase  the Shares  under this Section
2(a).

          (b) The Company may exercise the right and option  provided in Section
2(a) above by giving  written notice to the Selling  Stockholder  not later than
the close of business on the date of  expiration of such right and option (or if
such date is not a business  day, then on or before the close of business on the
next succeeding business day), advising of the election to exercise the same and
the date (not later than ten (10) days from the date of expiration of such first
right and option to purchase the Shares under  Section  2(a)) upon which payment
of the  purchase  price for the Shares  shall be made.  The Selling  Stockholder
shall cause to be delivered to the Company at the Company's principal office, on
the  payment  date  specified  in  such  written  notice,   the  certificate  or
certificates  representing the Shares,  properly endorsed for transfer,  against
payment of the purchase price  therefor by the Company in immediately  available
funds.

          (c) In the event  that the  Shares are not  purchased  by the  Company
hereunder,  the Selling Stockholder shall next give notice (the "Second Notice",
and together with the Notice, the "Notices") to the other Stockholder,  by which
the  Selling  Stockholder  shall  then  offer  to  the  other  Stockholder  (the
"Offeree")  the right and  option to  purchase  all but not less than all of the
Shares for cash at the same  purchase  price and on the same terms as offered to
the  Company as set forth in the Notice.  Pursuant  to such  offer,  the Offeree
shall  have the right and  option to  purchase  all but not less than all of the
Shares,  for  cash  at a  purchase  price  equal  to the  dollar  value  of such
consideration (in the event such consideration  includes noncash  consideration,
subject to Section 2(g) hereof,  the dollar value of such noncash  consideration
shall be determined



                                     - 2 -


by the Company's Board of Directors, provided that if the Selling Stockholder or
the Offeree is a member of the Board of Directors,  he shall not  participate in
such determination),  exercisable for a period of ten (10) days from the date of
receipt of the Second  Notice.  Failure of the  Offeree to respond to the Second
Notice  within  the ten  (10)  day  period  shall  be  deemed  to  constitute  a
notification  to the  Selling  Stockholder  of  the  Offeree's  decision  not to
exercise the right and option to purchase the Shares under this Section 2(c).

               (d) The Offeree may exercise  the rights and options  provided in
Section 2(c) by giving written notice to the Selling  Stockholder not later than
the close of business on the date of  expiration of such right and option (or if
such date is not a business  day, then on or before the close of business on the
next succeeding business day), advising of the election to exercise the same and
the date (not later than ten (10) days from the date of expiration of the notice
upon which the Offeree is acting) upon which  payment of the purchase  price for
the Shares shall be made. The Selling Stockholder shall cause to be delivered to
the Offeree at the Company's  principal office, on the payment date specified in
such written notice,  the certificate or  certificates  representing  the Shares
being purchased by the Offeree, properly endorsed for transfer,  against payment
of the purchase price therefor.

               (e) If the Shares are not purchased by the Company or the Offeree
in  accordance  with this  Section 2, the Selling  Stockholder  may,  during the
ninety (90) day period  commencing  on the  expiration of the rights and options
provided for in Sections 2(a) and 2(c),  sell all, but not less than all, of the
Shares to the  transferee  named in the  Notices for  consideration,  the dollar
value of which is equal to or greater than the dollar value of the consideration
specified in the  Notices,  free of the  restrictions  contained in Section 2 of
this Agreement.

               (f)  Notwithstanding  the  foregoing,  any of the  Sirota  Shares
distributed to the Company in satisfaction of an  indemnification  claim made by
the Company or Unison under the Asset  Purchase  Agreement  shall be free of the
restrictions contained in Section 2 of this Agreement. In addition, in the event
a Selling  Stockholder  desires to sell any of the Restricted Shares pursuant to
Rule 144  promulgated  under the Securities  Act of 1933, as amended,  such sale
shall be free of the  restrictions  contained  in  Section 2 of this  Agreement,
provided such sale does not result in such Selling Stockholder selling in excess
of 10,000  shares  of  Common  Stock in the  immediately  preceding  three-month
period.

               (g) In the event the Selling  Stockholder  disputes  the Board of
Directors' determination of the dollar value of noncash consideration to be paid
for the Shares,  such  Selling  Stockholder  shall notify the Company in writing
within  three (3)  calendar  days after  such  determination  setting  forth the
amount, nature and basis of the dispute.

               Within the following  five (5) days,  the parties shall use their
best efforts to resolve such  dispute.  Upon their failure to do so, the dispute
shall be submitted for arbitration as follows:

                    (i) The arbitrator shall be a public accounting firm located
in the City of New York, State of New York. In the event the selected arbitrator
declines or is unable to serve for any reason,  the parties shall select another
arbitrator. Upon their failure to agree on


                                     - 3 -


another  arbitrator,  the  jurisdiction of the Supreme Court of the State of New
York shall be invoked to make such selection.

                    (ii) The arbitrator shall follow the Commercial  Arbitration
Rules of the American  Arbitration  Association,  except as  otherwise  provided
herein.  The arbitrator shall  substantially  comply with the rules of evidence;
shall grant essential but limited  discovery;  shall provide for the exchange of
witness  lists and  exhibit  copies;  shall  conduct  a  pretrial  and  consider
dispositive  motions.  Each party shall have the right to request the arbitrator
to make findings of specific factual issues.

          The arbitrator  shall complete its proceedings and render its decision
within  forty (40) days after  submission  of the  dispute  to it,  unless  both
parties agree to an extension. Each party shall cooperate with the arbitrator to
comply with the procedural time  requirements and the failure of either to do so
shall entitle the arbitrator to extend the arbitration  proceedings  accordingly
and to impose sanctions on the party  responsible for the delay,  payable to the
other party.

          In the event the arbitrator does not fulfill its responsibilities on a
timely basis, either party shall have the right to require a replacement and the
appointment of a new arbitrator.

               (iii) The decision of the  arbitrator  shall be final and binding
upon the parties and accordingly a judgment by a court of competent jurisdiction
may be entered in accordance therewith.

          SECTION 3. Election of Directors. At any time at which stockholders of
the Company  will have the right to vote or will vote all shares of Common Stock
of  the  Company  in  matters  relating  to  the  election  of  directors,  each
Stockholder  shall vote all shares of Common Stock  presently owned or hereafter
acquired by him to cause and  maintain the election to the Board of Directors of
the  Company  of  the  other  Stockholder;   provided,   however,  that  neither
Stockholder shall have any such obligation under this Section 3 in the event the
other  Stockholder  no longer owns at least ten percent  (10%) of the  Company's
then issued and outstanding shares of Common Stock.

          SECTION 4. Standstill  Agreement.  Sirota hereby agrees that,  without
the prior  written  consent of Dye, he shall not take any action to cause him to
be the beneficial  owner of more than 1,000,000  shares of the Company's  Common
Stock.

          SECTION 5. Purchasers or Transferees of Restricted  Shares.  Except as
otherwise  specifically  provided  herein,  any person who shall acquire (either
voluntarily or  involuntarily,  by operation of law or otherwise) any Restricted
Shares from a  Stockholder  or any Permitted  Transferee,  shall be bound by the
provisions of this Agreement  relating to the voting,  transfer and sale of such
Restricted  Shares to the same  extent as the parties  hereto and,  prior to the
registration of the transfer of any such  Restricted  Shares on the books of the
Company,  any purchaser or other  transferee shall execute a counterpart to this
Agreement agreeing to be bound by such provisions.



                                     - 4 -


          SECTION  6.  Legend  on Stock  Certificates.  During  the term of this
Agreement, each certificate issued after the date hereof representing Restricted
Shares held by a Stockholder shall conspicuously bear the following legend until
such  time as the  shares  represented  thereby  are no  longer  subject  to the
provisions hereof:

               "THE SHARES  REPRESENTED BY THIS  CERTIFICATE  ARE SUBJECT TO THE
               TERMS AND CONDITIONS OF A  STOCKHOLDERS'  AGREEMENT,  DATED AS OF

     imposition of any lien, charge or encumbrance of any nature whatsoever upon
