               Warrant for the Purchase of Shares of Common Stock

No. 1999-1                                                         46,535 Shares

               FOR VALUE RECEIVED,  ACCENT COLOR  SCIENCES,  INC., a Connecticut
corporation  (the  "Company"),  with its  principal  office  at 800  Connecticut
Boulevard, East Hartford,  Connecticut 06108, hereby certifies that Pennsylvania
Merchant  Group (the  "Holder") is entitled,  subject to the  provisions of this
Warrant,  to purchase  from the  Company,  at any time after the date hereof and
continuing  for a period of five (5) years (the  "Expiration  Date"),  up to the
number of fully paid and nonassessable shares of Common Stock of the Company set
forth above, subject to adjustment as hereinafter provided.

               The Holder may purchase  such number of shares of Common Stock at
a purchase  price per share (as  appropriately  adjusted  pursuant  to Section 6
hereof) of $.40 (the "Exercise  Price").  The term "Common Stock" shall mean the
aforementioned  Common  Stock of the  Company,  together  with any other  equity
securities  that  may be  issued  by  the  Company  in  addition  thereto  or in
substitution therefor as provided herein.

               The  number of shares of  Common  Stock to be  received  upon the
exercise  or  exchange  of this  Warrant and the price to be paid for a share of
Common  Stock are subject to  adjustment  from time to time as  hereinafter  set
forth. The shares of Common Stock deliverable upon such exercise or exchange, as
adjusted from time to time, are  hereinafter  sometimes  referred to as "Warrant
Shares."

               Section 1. Exercise of Warrant; Cashless Exercise.

               (a)  This  Warrant  may be  exercised  in whole or in part on any
business day on or before the  Expiration  Date by  presentation  and  surrender
hereof

<PAGE>
to the Company at its  principal  office at the address set forth in the initial
paragraph  hereof (or at such other address as the Company may hereafter  notify
the Holder in writing) with the Purchase  Form annexed  hereto duly executed and
accompanied  by proper  payment  of the  Exercise  Price in lawful  money of the
United States of America in the form of a check, subject to collection,  for the
number of Warrant Shares  specified in the Purchase Form. If this Warrant should
be exercised in part only,  the Company  shall,  upon surrender of this Warrant,
execute and deliver a new Warrant evidencing the rights of the Holder thereof to
purchase the balance of the Warrant Shares purchasable  hereunder.  Upon receipt
by the Company of this  Warrant and such  Purchase  Form,  together  with proper
payment of the Exercise Price, at such office,  the Holder shall be deemed to be
the  holder of  record of the  Warrant  Shares,  notwithstanding  that the stock
transfer  books  of the  Company  shall  then be  closed  or  that  certificates
representing  such Warrant  Shares  shall not then be actually  delivered to the
Holder.  The Company shall pay any and all documentary stamp or similar issue or
transfer  taxes  payable  in  respect of the issue or  delivery  of the  Warrant
Shares.

               (b) In addition to the rights of the Holder under  paragraph  (a)
above, the Holder shall have the right to exercise this Warrant,  in whole or in
part, in lieu of paying the Exercise Price in cash, by  instructing  the Company
to issue that number of Warrant Shares  determined by multiplying  the number of
Warrant  Shares  in  respect  of which  this  Warrant  is being  exercised  by a
fraction,  the  numerator  of which shall be the  difference  between the Market
Price (as defined in Section  6(g) below) per share of Common  Stock on the date
of exercise and the Exercise  Price,  and the denominator of which shall be such
Market Price per share of Common Stock.

               Section 2. Reservation of Shares.  The Company hereby agrees that
at all times there shall be reserved for issuance and delivery  upon exercise or
exchange  of this  Warrant  all  shares of its Common  Stock or other  shares of
capital  stock of the  Company  from  time to time  issuable  upon  exercise  or
exchange of this  Warrant.  All such shares shall be duly  authorized  and, when
issued upon the exercise or exchange of the Warrant in accordance with the terms
hereof, shall be validly issued, fully paid and nonassessable, free and clear of
all liens, security interests, charges and other encumbrances or restrictions on
sale (other than any  restrictions  on sale pursuant to  applicable  federal and
state securities laws) and free and clear of all preemptive rights.

               Section 3. Fractional Interest; Market Price.

               (a) The Company will not issue a fractional share of Common Stock
upon exercise or exchange of this Warrant. Instead, the Company will deliver its
check for the current market value of the fractional  share.  The current market
value of a fraction of a share is  determined  as follows:  multiply  the Market
Price of a full  share by the  fraction  of a share and round the  result to the
nearest cent.

               (b) For purposes of Section 3(a),  the Market Price of a share of
Common Stock is, if the Common Stock is then publicly  traded,  the Quoted Price
(as defined in Section  6(g) below) of the Common  Stock on the last trading day

<PAGE>
prior to the date of exercise or exchange,  and otherwise  shall be equal to the
Exercise Price.

               Section 4. Assignment or Loss of Warrant.

               (a) Except as provided  in Section 9, the Holder of this  Warrant
shall be entitled,  without obtaining the consent of the Company,  to assign its
interest in this Warrant,  or any of the Warrant Shares,  in whole or in part to
any bona fide officer,  director or partner of Holder,  provided,  however, that
the  transferee,  prior to any such  transfer,  agrees in  writing,  in form and
substance  satisfactory  to the  Company,  to be  bound  by the  terms  of  this
Agreement  as if  originally  a party  hereto and  provides  the Company with an
opinion of counsel in such form  reasonably  acceptable  to the  Company and its
counsel,  that  such  transfer  would  not be in  violation  of  the  Act or any
applicable state securities or blue sky laws.  Subject to the provisions  hereof
and of Section 9, upon surrender of this Warrant to the Company or at the office
of its stock transfer agent or warrant agent,  with the Assignment  Form annexed
hereto  duly  executed  and funds  sufficient  to pay any  transfer or other tax
payable in respect  thereof,  the Company  shall,  without  charge,  execute and
deliver a new Warrant or Warrants in the name of the assignee or assignees named
in such  instrument of assignment  and, if the Holder's  entire  interest is not
being  assigned,  in the name of the Holder,  and this Warrant shall promptly be
canceled.

               (b) Upon receipt of evidence  satisfactory  to the Company of the
loss,  theft,  destruction  or mutilation  of this Warrant,  and (in the case of
loss, theft or destruction) of indemnification  satisfactory to the Company, and
upon surrender and cancellation of this Warrant, if mutilated, the Company shall
execute and deliver a new Warrant of like tenor and date.

               Section 5. Rights of the Holder.  The Holder shall not, by virtue
hereof, be entitled to any rights of a shareholder in the Company, either at law
or equity,  and the rights of the Holder are  limited to those set forth in this
Warrant. Nothing contained in this Warrant shall be construed as conferring upon
the Holder  hereof  the right to vote or to  consent  or to receive  notice as a
shareholder  of the  Company  on any  matters  or  with  respect  to any  rights
whatsoever as a shareholder  of the Company.  No dividends or interest  shall be
payable or accrued in respect of this Warrant or the interest represented hereby
or the Warrant Shares purchasable  hereunder until, and only to the extent that,
this Warrant  shall have been  exercised or  exchanged  in  accordance  with its
terms.

               Section 6. Adjustment of Exercise Price and Number of Shares. The
number and kind of securities  purchasable upon the exercise or exchange of this
Warrant and the Exercise Price shall be subject to adjustment  from time to time
upon the occurrence of certain events, as follows:

               (a) Adjustment for Change in Capital Stock.  If at any time after
December 7, 1999, the Company:

<PAGE>
                    (A)  pays a dividend or makes a  distribution  on its Common
                         Stock, in either case in shares of its Common Stock;

                    (B)  subdivides its outstanding  shares of Common Stock into
                         a greater number of shares;

                    (C)  combines its outstanding  shares of Common Stock into a
                         smaller number of shares; or

                    (D)  makes a  distribution  on its Common Stock in shares of
                         its capital stock other than Common Stock;

then the  Exercise  Price in effect  immediately  prior to such action  shall be
adjusted  so that the Holder may  receive,  upon  exercise  or  exchange of this
Warrant and payment of the same aggregate consideration, the number of shares of
capital  stock of the  Company  which the Holder  would  have owned  immediately
following  such  action if the Holder had  exercised  or  exchanged  the Warrant
immediately prior to such action.

          The adjustment  shall become  effective  immediately  after the record
date in the  case of a  dividend  or  distribution  and  immediately  after  the
effective date in the case of a subdivision, combination or reclassification.

          (b) Adjustment for Other Distributions.  If at any time after December
7, 1999, the Company distributes to all of its Common Stock any of its assets or
debt securities,  the Exercise Price following the record date shall be adjusted
in accordance with the following formula:

                                            E' = E x  M-F
                                                      ---
                                                       M

where:   E'       =        the adjusted Exercise Price.

                  E        =        the Exercise Price immediately prior to  the
                                    adjustment.

                  M        =        the Market Price (as defined  in (g) below)
                                    per share of Common Stock on the record date
                                    of the distribution.

                  F        =        the   aggregate   fair   market   value  (as
                                    conclusively  determined  by  the  Board  of
                                    Directors of the Company) on the record date
                                    of  the  assets  or  debt  securities  to be
                                    distributed   divided   by  the   number  of
                                    outstanding shares of Common Stock.

          The  adjustment   shall  be  made   successively   whenever  any  such
distribution  is made and shall become  effective  immediately  after the record
date for the determination of shareholders entitled to receive the distribution.
In the event

<PAGE>
that such  distribution  is not actually made, the Exercise Price shall again be
adjusted  to the  Exercise  Price as  determined  without  giving  effect to the
calculation provided hereby. In no event shall the Exercise Price be adjusted to
an amount less than zero.

          This subsection does not apply to cash dividends or cash distributions
paid out of consolidated  current or retained  earnings as shown on the books of
the Company and paid in the ordinary course of business.

          (c) Adjustment  for Common Stock Issue.  If at any time after December
7, 1999, the Company issues shares of Common Stock for  consideration  per share
less  than the  Exercise  Price  per  share on the date the  Company  fixes  the
offering price of such additional  shares,  the Exercise Price shall be adjusted
in accordance with the following formula:

                                                        O + P
                                                            --
                                            E' = E x        E
                                                     ---------
                                                          A

where:   E'       =        the adjusted Exercise Price.

                  E        =        the Exercise Price immediately prior to the
                                    adjustment.

                  O        =        the number of shares outstanding immediately
                                    prior  to the  issuance  of such  additional
                                    shares.

                  P        =        the  aggregate   consideration received  for
                                    the  issuance  of  such additional shares.

                  A        =        the   number   of   shares   outstanding
                                    immediately   after  the  issuance  of  such
                                    additional shares.

          The adjustment shall be made  successively  whenever any such issuance
is made, and shall become effective immediately after such issuance.

         This  subsection  (c)  does not  apply  to (i) any of the  transactions
described in  subsections  (b) and (d),  (ii) Common  Stock  issued  pursuant to
options,  warrants,  convertible  preferred  stock and other  rights to purchase
shares of Common  Stock  outstanding  on December 7, 1999,  (iii)  Common  Stock
issued to  shareholders of any  non-affiliated  person which merges into or with
the Company,  or any  subsidiary  of the Company,  in  proportion to their stock
holdings of such person  immediately prior to such merger,  upon such merger, or
(iv) Common Stock issued to directors or employees  of, or  consultants  to, the
Company upon the exercise of  warrants,  rights or options  which (A) are issued
pursuant to stock option plans, employee benefit plans, employment agreements or
consulting agreements, in each case approved by the Company's Board of Directors
or an appropriate committee of the Company's Board of Directors, and (B) have an
exercise  price not less than 70% of the Market  Price of the  Company's  Common
Stock at the time of issuance of such warrant, right or option.

<PAGE>
          (d) Adjustment for Convertible  Securities Issue. If at any time after
December  7,  1999,  the  Company  issues  for   consideration   any  securities
convertible  into or  exchangeable  or exercisable  for Common Stock (other than
securities  issued in  transactions  described  in  subsection  6(a)  above) for
consideration  per share of Common Stock initially  deliverable upon conversion,
exchange or exercise of such  securities  less than the Exercise Price per share
on the date of issuance of such securities, the Exercise Price shall be adjusted
in accordance with the following formula:

                                                        O + P
                                                            --
                                            E' = E x        E
                                                     --------
                                                        O + D

where:   E'       =        the adjusted Exercise Price.

                  E        =        the then current Exercise Price.

                  O        =        the number of shares outstanding immediately
                                    prior to the issuance of such securities.

                  P        =        the  aggregate  consideration  received  for
                                    the  issuance  of  such securities.

                  D        =        the  maximum  number of  shares  deliverable
                                    upon  conversion,  exchange  or  exercise of
                                    such  securities at the initial  conversion,
                                    exchange or exercise rate.

          The adjustment shall be made  successively  whenever any such issuance
is made, and shall become effective  immediately after such issuance.  If all of
the Common  Stock  deliverable  upon  conversion,  exchange  or exercise of such
securities has not been issued when such  securities are no longer  outstanding,
then the Exercise Price shall promptly be readjusted to the Exercise Price which
would then be in effect had the adjustment  upon the issuance of such securities
been made on the basis of the  actual  number of shares of Common  Stock  issued
upon conversion, exchange or exercise of such securities.

          This  subsection  (d)  does not  apply to (i) any of the  transactions
described in subsections (b) and (c) above, (ii) securities  convertible into or
exchangeable  or  exercisable  for Common  Stock issued to  shareholders  of any
non-affiliated  person which merges into or with the Company,  or any subsidiary
of the Company, in proportion to their stock holdings of such person immediately
prior to such merger,  upon such merger,  or (iii)  warrants,  rights or options
which (A) are issued  pursuant to stock option plans,  employee  benefit  plans,
employment  agreements  or consulting  agreements,  in each case approved by the
Company's Board of Directors or an appropriate  committee of the Company's Board
of Directors,  and (B) have an exercise price of not less than 70% of the Market
Price of the  Company's  Common Stock at the time of issuance of such  warrants,
right, warrant or option.

          (e)  Deferral of  Issuance  or Payment.  In any case in which an event
covered by this Section 6 shall require that an adjustment in the Exercise Price
be made  effective as of a record date, the Company may elect to defer until the

<PAGE>
actual  occurrence  of such event (i) issuing to the Holder,  if this Warrant is
exercised  after such record date,  the shares of Common Stock and other capital
stock of the Company,  if any,  issuable  upon such  exercise over and above the
shares of Common Stock or other capital stock of the Company,  if any,  issuable
upon such  exercise on the basis of the  Exercise  Price in effect prior to such
adjustment,  and (ii)  paying to the  Holder by check any  amount in lieu of the
issuance of fractional shares pursuant to Section 3.

          (f) When No  Adjustment  Required.  No  adjustment  need be made for a
change in the par value of the Common Stock.

          (g) Market Price.  The "Market Price" per share of Common Stock on any
date  is the  average  of the  Quoted  Prices  of the  Common  Stock  for the 30
consecutive trading days commencing 45 trading days before the date in question.
The "Quoted  Price" of the Common Stock is the last reported  sales price of the
Common Stock as reported by Nasdaq, or the primary national  securities exchange
on which the Common Stock is then quoted; provided,  however, that if quotes for
the Common  Stock are not  reported  by Nasdaq  and the Common  Stock is neither
traded on the Nasdaq National Market, on a national securities exchange,  on the
Nasdaq  Small Cap Market nor on the OTC  Electronic  Bulletin  Board,  the price
referred to above shall be the price reflected in the over-the-counter market as
reported by the National Quotation Bureau, Inc. or any organization performing a
similar function,  and provided,  further,  that if the Common Stock is not then
publicly traded, the Market Price shall equal the Conversion Price.

          (h) No Adjustment Upon Exercise of Warrants.  No adjustments  shall be
made under any Section herein in connection  with the issuance of Warrant Shares
upon exercise or exchange of the Warrants.

          (i) Common Stock Defined.  Whenever  reference is made in Section 6(a)
to the issue of shares of Common  Stock,  the term "Common  Stock" shall include
any equity securities of any class of the Company  hereinafter  authorized which
shall not be limited to a fixed sum or percentage in respect of the right of the
holder thereof to participate in dividends or  distributions  of assets upon the
voluntary or involuntary liquidation,  dissolution or winding up of the Company.
Subject to the  provisions of Section 8 hereof,  however,  shares  issuable upon
exercise or exchange hereof shall include only shares of the class designated as
Common  Stock of the  Company  as of the date  hereof  or shares of any class or
classes resulting from any reclassification or reclassifications thereof or as a
result of any corporate reorganization as provided for in Section 8 hereof.

          Section 7. Officers' Certificate. Whenever the Exercise Price shall be
adjusted as required by the provisions of Section 6, the Company shall forthwith
file in the custody of its secretary or an assistant  secretary at its principal
office an officers'  certificate  showing the adjusted Exercise Price determined
as herein provided,  setting forth in reasonable detail the facts requiring such
adjustment  and the manner of computing  such  adjustment.  Each such  officers'
certificate  shall be  signed  by the  chairman,  president  or chief  financial
officer of the Company and by the  secretary or any  assistant  secretary of the
Company.  Each  such  officers'  certificate  shall  be  made  available  at all
reasonable  times  for  inspection  by the

<PAGE>
Holder or any holder of a Warrant  executed and delivered  pursuant to Section 4
hereof.

          Section 8. Reclassification,  Reorganization, Consolidation or Merger.
In the event of any reclassification,  capital reorganization or other change of
outstanding  shares of Common Stock of the Company  (other than a subdivision or
combination of the  outstanding  Common Stock and other than a change in the par
value of the Common Stock) or in the event of any consolidation or merger of the
Company  with or into another  corporation  (other than a merger in which merger
the  Company  is the  continuing  corporation  and that  does not  result in any
reclassification,  capital  reorganization or other change of outstanding shares
of Common Stock of the class issuable upon exercise or exchange of this Warrant)
or in  the  event  of  any  sale,  lease,  transfer  or  conveyance  to  another
corporation  of the  property  and  assets  of the  Company  as an  entirety  or
substantially  as an entirety,  the Company  shall use its best efforts to cause
effective  provisions  to be  made so that  the  Holder  shall  have  the  right
thereafter,  by  exercising  this  Warrant,  to purchase  the kind and amount of
shares of stock and other  securities and property  (including  cash) receivable
upon  such   reclassification,   capital   reorganization   and  other   change,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Common  Stock that would have been  received  upon  exercise or exchange of this
Warrant  immediately  prior to such  reclassification,  capital  reorganization,
change,  consolidation,  merger,  sale or conveyance.  Any such provision  shall
include  provisions for adjustments in respect of such shares of stock and other
securities and property that shall be as nearly equivalent as may be practicable
to the  adjustments  provided for in this Warrant.  The foregoing  provisions of
this Section 8 shall  similarly apply to successive  reclassifications,  capital
reorganizations  and  changes  of  shares  of  Common  Stock  and to  successive
consolidations, mergers, sales or conveyances.

          Section  9.  Transfer  to  Comply  with  the  Securities  Act of 1933;

legality, and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby. To the extent permitted by law, the parties hereto
waive the benefit of any  provision  of law that  renders any  provision of this

provided herein,  no failure or delay on the part of any party in exercising any
right,  power or remedy  hereunder shall operate as a waiver thereof,  nor shall
any single or partial  exercise of any such right,  power or remedy preclude any
other or further exercise  thereof or the exercise of any other right,  power or
remedy.

               (a)  Until the time set forth in Section 2.3(f) hereof, each time

                    its Common Stock,  other than (i) pursuant to a Registration

                    such  proposed  Registration  to all  holders  of Shares and
                    Warrant Shares,  which shall offer such holders the right to
                    request  inclusion  of  any  Registrable  Securities  in the
                    proposed Registration.

               (b)  Each  holder of Shares or Warrant  Shares  shall have thirty
                    (30) days or such longer period as shall be set forth in the

                    Company a written request specifying the number of shares of
                    Registrable  Securities  such holder intends to sell and the
                    holder's intended plan of disposition.

               (c)  The  Company  shall have the  exclusive  right to select all

                    securities of the Company,  including all Shares and Warrant
                    Shares.  In the event that the proposed  Registration by the
                    Company  is,  in whole or in part,  an  underwritten  public
                    offering of  securities  of the Company,  any request  under
                    Section 2.3(b) shall contain the holder's agreement that the
                    Registrable  Securities will be included in the underwriting
                    on the same  terms and  conditions  as the  shares of Common
                    Stock,  if any,  otherwise  being sold through  underwriters
                    under such Registration.

               (d)  Upon  receipt  of a  written  request  pursuant  to  Section
                    2.3(b),  the Company shall  promptly use its best efforts to
                    cause all such Registrable  Securities to be Registered,  to
                    the extent  required  to permit sale or  disposition  as set
                    forth in the written request.

<PAGE>
               (e)  Notwithstanding the foregoing,  if the managing  underwriter
                    of an underwritten public offering determines and advises in
                    writing  that the  inclusion of all  Registrable  Securities
                    proposed to be included in the underwritten public offering,
                    together with any shares  proposed to be sold by the Company
                    for its own  account  and any other  issued and  outstanding
                    shares of Common  Stock  proposed to be included  therein by
                    holders  other than the  holders of  Registrable  Securities
                    (such  other  holders'   shares   hereinafter   collectively
                    referred to as the "Other Shares"), would interfere with the
                    successful  marketing  of  the  securities  proposed  to  be
                    included in the underwritten public offering,  including the
                    price at which such  securities can be sold, then the number
                    of such  shares  of  persons  other  than the  Company  that
                    otherwise  would be  included  in such  underwritten  public
                    offering  shall be excluded  from such  underwritten  public
                    offering  in a  number  deemed  necessary  by such  managing
                    underwriter,  first by excluding,  to the extent  necessary,
                    Other  Shares  held  by  persons  who  have  not   exercised
                    contractual  rights to include  such Shares in the  offering
                    pursuant to the Prior  Registration  Rights  Agreements  (as
                    hereinafter defined), and then, to the extent necessary,  by
                    excluding  Registrable  Securities   participating  in  such
                    underwritten public offering,  pro rata, based on the number
                    of shares of Registrable  Securities each holder proposes to
                    include; and, then, excluding to the extent necessary, Other
                    Shares  proposed  to be  included  by the  holders  of Other
                    Shares who have  exercised  registration  rights  granted to
                    them under registration  rights agreements of the Company in
                    effect on the date hereof or any other  registration  rights
                    in  effect  on the date  hereof  (collectively,  the  "Prior
                    Registration Rights Agreements").

               (f)  The registration rights provided by this Agreement shall not
                    be in force with respect to any Registrable  Security if (i)
                    a  Registration  Statement  that  includes  the  Registrable
                    Security  is  effective;  (ii) the  Registrable  Security is
                    eligible  for resale  under Rule 144  without  regard to the
                    volume  limitations  thereof;  and (iii) five years form the
                    date hereof have elapsed.

          2.4  Preparation  and Filing.  If and whenever the Company is under an
               obligation  pursuant to the  provisions  of this Section 2 to use
               its best efforts to effect,  the  Registration of any Registrable
               Securities, the Company shall, as expeditiously as practicable:

               (a)  prepare  and  file  with  the   Commission  a   Registration
                    Statement with respect to such Registrable Securities, using
                    such  form  of  available   Registration   Statement  as  is
                    reasonably   selected  by  the  Company  (unless   otherwise
                    specified  herein),  and use its best  efforts to cause such
                    Registration  Statement  to  become  and  remain  effective,

<PAGE>
                    keeping   each  Selling   Shareholder   advised  as  to  the
                    initiation, progress and completion of the Registration;

               (b)  prepare and file with the  Commission  such  amendments  and
                    supplements   to  such   Registration   Statements  and  the
                    prospectus used in connection  therewith as may be necessary
                    to keep such  Registration  Statement  effective for, in the
                    case of a  Required  Registration  under  Section  2.2,  the

                    Piggyback Registration under Section 2.3, six months, and to
                    comply  with  the  provisions  of the  Securities  Act  with

                    of the  Securities  Act,  and such other  documents  as such
                    Selling  Shareholder  may  reasonably  request  in  order to
                    facilitate  the  public  sale or other  disposition  of such
                    Registrable  Securities;  provided,  however,  that  no such
                    prospectus  need be  furnished  more than,  in the case of a
                    Required  Registration  under  Section 2.2, six months after
                    the  conclusion  of the period  set forth in Section  2.2(b)
                    and, in the case of a Piggyback  Registration  under Section

                    Selling  Shareholder shall reasonably request and do any and
                    all other acts or things which may be  reasonably  necessary
                    or advisable to enable such holder to consummate  the public
                    sale or  other  disposition  in such  jurisdictions  of such
                    Registrable Securities;  provided, however, that the Company
                    shall not be  required  to  consent  to  general  service of
                    process,  qualify to do  business  as a foreign  corporation
                    where it would  not be  otherwise  required  to  qualify  or

                    liable for such taxes; and

               (e)  at any time when a prospectus  covered by such  Registration
                    Statement is required to be delivered  under the  Securities
                    Act  within  the  appropriate  period  mentioned  in Section
                    2.2(b) or Section 2.3(b) hereof,  as the case may be, notify
                    each Selling  Shareholder of the happening of any event as a
                    result of which the prospectus included in such Registration
                    Statement,  as then in effect,  includes an untrue statement
                    of a  material  fact  or  omits  to  state a  material  fact
                    required  to be  stated  therein  or  necessary  to make the
                    statements  therein  not  misleading  in  the  light  of the
                    circumstances  then  existing  and,  at the  request of such
                    seller,   prepare,   file  and  furnish  to  such  seller  a
                    reasonable  number  of  copies  of a  supplement  to  or  an
                    amendment of

<PAGE>
                    such  prospectus  as may be necessary so that, as thereafter
                    delivered to the purchasers of such shares,  such prospectus
                    shall not include an untrue  statement of a material fact or
                    omit to state a material fact required to be stated  therein
                    or necessary to make the statement therein not misleading in
                    the light of the  circumstances  then existing.  The Company
                    may delay  amending or  supplementing  the  prospectus for a
                    period not to exceed 45 days if the Company is then  engaged
                    in negotiations  regarding a material  transaction  that has
                    not  otherwise  been  publicly  disclosed,  and the  Selling
                    Shareholders  shall  suspend  their sale of Shares  until an
                    appropriate  supplement or prospectus  has been forwarded to
                    them or the proposed transaction is abandoned.

                    Notwithstanding the foregoing,  with respect to the proposed
                    Registration of Registrable  Securities  pursuant to Section
                    2.3 hereof,  the Company  may  withdraw or cease  proceeding
                    with any proposed Registration of Registrable  Securities if
                    it has  withdrawn  or ceased  proceeding  with the  proposed
                    Registration  of Common  Stock of the Company with which the
                    Registration  of  such  Registrable  Securities  was  to  be
                    included.

          2.5  Expenses.   The  Company  shall  pay  all  Registration  Expenses
               incurred by the Company in complying with this Section 2.

          2.6  Information  Furnished  by  Purchaser.  It shall  be a  condition
               precedent to the Company's obligations under this Agreement as to
               any Selling  Shareholder that each Selling Shareholder furnish to
               the Company in writing such  information  regarding  such Selling
               Shareholder  and  the  distribution   proposed  by  such  Selling
               Shareholder as the Company may reasonably request.

          2.7  Indemnification.

               2.7.1    Company's  Indemnification  of  Purchasers.  The Company

                        person controlling (within the meaning of the Securities
                        Act)  such  Selling  Shareholder,  against  all  claims,
                        losses,  damages or  liabilities  (or actions in respect
                        thereof)  suffered or  incurred  by any of them,  to the
                        extent such claims, losses, damages or liabilities arise
                        out  of or are  based  upon  any  untrue  statement  (or
                        alleged  untrue  statement) of a material fact contained
                        in any prospectus or any related Registration  Statement
                        incident to any such  Registration,  or any omission (or
                        alleged  omission)  to state  therein  a  material  fact
                        required to be stated  therein or  necessary to make the
                        statements  therein not misleading,  or any violation by
                        the Company of any rule or regulation  promulgated under
                        the   Securities  Act  applicable  to  the  Company  and
                        relating to actions or inaction  required of the Company
                        in  connection  with  any  such  Registration;  and  the
                        Company will  reimburse  each such Selling  Shareholder,
                        each of its officers, directors and constituent partners
                        and  each   person  who   controls   any  such   Selling
                        Shareholder,  for any

<PAGE>
                        reasonable, documented legal and other expenses incurred
                        in connection with  investigating  or defending any such
                        claim,  loss,  damage,  liability  or action;  provided,
                        however,  that the  indemnity  contained in this Section
                        2.7.1 shall not apply to amounts paid in  settlement  of
                        any such claim,  loss,  damage,  liability  or action if
                        settlement  is  effected  without  the  consent  of  the
                        Company  (which  consent  shall  not   unreasonably   be
                        withheld); and provided,  further, that the Company will
                        not be liable in any such  case to the  extent  that any
                        such claim,  loss,  damage,  liability or expense arises
                        out of or is based upon any untrue (or  alleged  untrue)
                        statement  or omission  based upon  written  information
                        furnished  to the Company by such  Selling  Shareholder,
                        underwriter,  controlling  person  or other  indemnified
                        person and stated to be for use in  connection  with the
                        offering of securities of the Company.

                  2.7.2 Selling  Shareholder's  Indemnification of Company. Each
                        Selling Shareholder shall indemnify the Company, each of
                        its directors and officers, each underwriter, if any, of
                        the  Company's  securities  covered  by  a  Registration
                        Statement,  each person who controls the Company or such
                        underwriter  within the meaning of the  Securities  Act,
                        and  each  other  Selling   Shareholder,   each  of  its

                        person  controlling  such  other  Selling   Shareholder,
                        against all claims,  losses, damages and liabilities (or
                        actions in respect thereof)  suffered or incurred by any
                        of them  and  arising  out of or based  upon any  untrue
                        statement  (or alleged  untrue  statement) of a material
                        fact contained in such Registration Statement or related
                        prospectus,  or any  omission  (or alleged  omission) to
                        state  therein a  material  fact  required  to be stated
                        therein or necessary to make the statements  therein not
                        misleading, or any violation by such Selling Shareholder
                        of  any  rule  or  regulation   promulgated   under  the
                        Securities  Act  applicable to such Selling  Shareholder
                        and  relating  to actions or  inaction  required of such

                        of  the   Registrable   Securities   pursuant   to  such
                        Registration Statement;  and will reimburse the Company,
                        such  other  Selling   Shareholders,   such   directors,
                        officers,    partners,    persons,    underwriters   and
                        controlling persons for any reasonable, documented legal

                        statement (or alleged untrue  statement) or omission (or
                        alleged omission) is made in such Registration Statement

                  2.7.3 Indemnification Procedure.  Promptly after receipt by an
                        indemnified  party  under this  Section 2.7 of notice of
                        the  commencement of any action which may give rise to a
                        claim for  indemnification  hereunder,  such indemnified
                        party will, if a claim in respect  thereof is to be made
                        against an  indemnifying  party under this  Section 2.7,
                        notify  the   indemnifying   party  in  writing  of  the
                        commencement   thereof  and  generally   summarize  such
                        action.  The indemnifying  party shall have the right to
                        participate  in and to assume the defense of such claim,
                        and shall be entitled to select  counsel for the defense
                        of such claim with the approval of any parties  entitled
                        to   indemnification,   which   approval  shall  not  be
                        unreasonably  withheld.  Notwithstanding  the foregoing,
                        the parties entitled to  indemnification  shall have the
                        right   to   employ   separate    counsel    (reasonably
                        satisfactory to the  indemnifying  party) to participate
                        in the  defense  thereof,  but the fees and  expenses of
                        such  separate  counsel  shall be at the expense of such
                        indemnified  parties  unless  the named  parties to such
                        action  or  proceedings  include  both the  indemnifying
                        party and the indemnified  parties and the  indemnifying
                        party  or  such  indemnified  parties  shall  have  been
                        advised  by  counsel  that  there are one or more  legal
                        defenses available to the indemnified  parties which are
                        different  from or additional to those  available to the
                        indemnifying  party (in which case,  if the  indemnified
                        parties  notify the  indemnifying  party in writing that
                        they elect to employ separate  counsel at the reasonable
                        expense  of the  indemnifying  party,  the  indemnifying
                        party  shall not have the right to assume the defense of
                        such action or proceeding  on behalf of the  indemnified
                        parties,   it  being  understood,   however,   that  the
                        indemnifying  party  shall not, in  connection  with any
                        such action or proceeding  or separate or  substantially
                        similar  or  related  action or  proceeding  in the same
                        jurisdiction arising out of the same general allegations
                        or   circumstances,   be  liable  for  the   reasonable,
                        documented  fees and  expenses of more than one separate
                        counsel at any time for all indemnified  parties,  which
                        counsel shall be designated in writing by the Purchasers
                        of a majority of the Registrable Securities).

                  2.7.4 Contribution.  If the  indemnification  provided  for in
                        this   Section  2.7  from  an   indemnifying   party  is
                        unavailable to an indemnified party hereunder in respect
                        to any losses, claims, damages,  liabilities or expenses
                        referred to herein, then the indemnifying party, in lieu
                        of indemnifying such indemnified party, shall contribute
                        to the amount paid or payable by such indemnified  party
                        as a result of such losses, claims, damages, liabilities
                        or  expenses in such  proportion  as is  appropriate  to
                        reflect the relative fault of the indemnifying party and
                        indemnified  party in connection  with the statements or
                        omissions which result in such losses, claims,  damages,
                        liabilities  or expenses,  as well as any other relevant
                        equitable  considerations.  The  relative  fault of such
                        indemnifying   party  and  indemnified  party  shall  be
                        determined by reference to, among other things,  whether
                        the untrue or  alleged  untrue  statement  of a material
                        fact or the  omission  or

<PAGE>
                        alleged  omission  to state a material  fact  relates to
                        information  supplied  by  such  indemnifying  party  or
                        indemnified  party  and the  parties'  relative  intent,
                        knowledge,   access  to  information  supplied  by  such
                        indemnifying  party or indemnified party and opportunity
                        to correct or prevent such  statement  or omission.  The
                        amount  paid or  payable  by a party as a result  of the
                        losses,  claims,   damages,   liabilities  and  expenses
                        referred  to  above  shall  be  deemed  to  include  any
                        documented  legal or other fees or  expenses  reasonably
                        incurred by such party in connection with  investigating
                        or defending any action,  suit,  proceeding or claim, or
                        in collecting such indemnity or  reimbursement  from the
                        indemnifying party.

3. Covenants of the Company.

          The Company agrees to:

          (a)  Notify  the  holders  of  Registrable  Securities  included  in a
               Registration  Statement of (i) the issuance by the  Commission of
               any stop order suspending the  effectiveness of such Registration
               Statement  and  (ii)  upon  learning  of  the  initiation  of any
               proceedings for the purpose of suspending such effectiveness, the
               existence  of such  proceedings.  The  Company  will  make  every
               reasonable  effort to prevent the issuance of any stop order and,
               if any stop order is issued, to obtain the lifting thereof at the
               earliest possible time.

          (b)  If the  Common  Stock is then  listed  on a  national  securities
               exchange,   use  its  best  efforts  to  cause  the   Registrable
               Securities to be listed on such exchange.  If the Common Stock is
               not then listed on a national securities  exchange,  use its best
               efforts to facilitate the reporting of the Registrable Securities
               on NASDAQ.

          (c)  Take all other  reasonable  actions  necessary  to  expedite  and
               facilitate  disposition  of  the  Registrable  Securities  by the
               holders thereof pursuant to the Registration Statement.

          (d)  With a view to making  available  to the  holders of  Registrable
               Securities  the  benefits  of  Rule  144  promulgated  under  the
               Securities Act and any other rule or regulation of the Commission
               that may at any time permit the Purchasers to sell  securities of
               the  Company  to the public  without  registration,  the  Company
               agrees to:

               (i)  make and  keep  adequate  current  public  information  with
                    respect  to  the  Company  available,  as  those  terms  are
                    understood  and  defined in Rule 144,  at all times after 90
                    days  after the  effective  date of the  first  Registration
                    Statement  filed  by the  Company  for the  offering  of its
                    securities to the general public;

               (ii) file with the  Commission in a timely manner all reports and
                    other documents required of the Company under the Securities
                    Act and the  Securities  Exchange  Act of  1934  (the  "1934
                    Act"); and

<PAGE>

               (iii)furnish to each holder of Shares,  so long as such holder of
                    Shares owns any Shares, forthwith upon written request (a) a
                    written  statement  by  the  Company  as to  whether  it has
                    complied  with the reporting  requirements  of Rule 144, the
                    Securities  Act and the  1934  Act,  (b) a copy of the  most
                    recent  annual or  quarterly  report of the Company and such
                    other  reports and documents so filed by the Company and (c)
                    such other information as may be reasonably requested and as
                    is publicly  available  in availing the holders of Shares of
                    any rule or regulation of the  Commission  which permits the
                    selling of any such securities without registration.

          (e)  Prior to the filing of a Registration  Statement or any amendment
               thereto (whether  pre-effective or post-effective),  and prior to
               the filing of any  prospectus  or prospectus  supplement  related
               thereto,  the Company will provide each Selling  Shareholder with
               copies of all pages thereto, if any, which reference such Selling
               Shareholder.

          (b)  The terms and  conditions  of this  Agreement  shall inure to the
               benefit  of and be binding  upon the  respective  successors  and
               assigns of the Purchaser (including  transferees of any shares of
               the Series C Stock or any Common Stock of the Corporation  issued
               upon  conversion  thereof).  Notwithstanding  the  foregoing,  no
               registration  rights  shall be  exercisable  with  respect to any
               share after such share has been sold  pursuant to a  Registration
               Statement declared effective under the Securities Act. Nothing in
               this  Agreement,  express or implied,  is intended to confer upon

               liabilities  under or by  reason  of this  Agreement,  except  as
               expressly provided in this Agreement.

          (c)  This Agreement and the other documents  delivered pursuant hereto
               constitute the full and entire  understanding and agreement among
               the parties with regard to the subjects hereof and no party shall
               be  liable  or bound to any  other  party  in any  manner  by any
               representations,  warranties,  covenants or agreements  except as
               specifically  set  forth  herein  or  therein.  Nothing  in  this
               Agreement,  express or  implied,  is  intended to confer upon any
               party,  other  than  the  parties  hereto  and  their  respective
               successors   and  permitted   assigns,   any  rights,   remedies,
               obligations, or liabilities under or by reason of this Agreement,
               except as expressly provided herein.

          (d)  In the  event  that  any  provision  of this  Agreement  shall be
               invalid,  illegal  or  unenforceable,  it  shall,  to the  extent
               practicable,  be  modified  so as to make  it  valid,  legal  and
               enforceable  and to retain as nearly as practicable the intent of
               the parties, and the validity legality, and enforceability of the

<PAGE>
               remaining provisions shall not in any way be affected or impaired
               thereby.  To the extent  permitted by law, the parties  waive the
               benefit of any provision of law that renders any provision of the
               Agreement invalid or unenforceable in any respect.

          (e)  Except as otherwise  provided herein,  any term of this Agreement
               may be amended,  and the observance of any term of this Agreement
               may be waived  (either  generally  or in a  particular  instance,
               either retroactively or prospectively, and either for a specified
               period of time or indefinitely),  with the written consent of the
               Company and the Purchaser.

          (f)  All  notices  and  other  communications  required  or  permitted
               hereunder  shall be in  writing  and shall be deemed  effectively
               given upon personal delivery, on the first business day following
               mailing  by  overnight  courier,  or on the fifth  day  following
               mailing  by  registered  or  certified   mail,   return   receipt
               requested,  postage  prepaid,  addressed  to the  Company  at its
               address  as  set  forth  in  the  Purchase  Agreement  and to the
               Purchaser at its address as shown on the books of the Company.

          (g)  The titles of the paragraphs and  subparagraphs of this Agreement
               are  for  convenience  of  reference  only  and  are  not  to  be
               considered in construing this Agreement.

          (h)  This  Agreement  may be executed  in any number of  counterparts,
               each of  which  shall be  deemed  an  original,  but all of which
               together shall constitute one instrument.

          (i)  No  waiver  by any  party  to this  Agreement  of any one or more
               defaults by any other party or parties in the  performance of any
               of the  provisions  hereof  shall  operate or be  construed  as a
               waiver of any future  default or  defaults,  whether of a like or
               different nature. Except as expressly provided herein, no failure
               or delay on the part of any party in exercising any right,  power
               or remedy hereunder shall operate as a waiver thereof,  nor shall
               any single or partial exercise of any such right, power or remedy
               preclude any other or further exercise thereof or the exercise of
               any other right, power or remedy.
