ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Company is a Connecticut corporation. Section 33-320a of the Connecticut
Stock Corporation Act ("Section 33-320a") provides that a corporation shall
indemnify any director or officer of the corporation against expenses
(including judgments, fines, penalties and amounts paid in settlement)
incurred by him in connection with any action, suit or proceeding other than
an action by or in the right of the corporation in which he is made or is
threatened to be made a party by reason of having been a director or officer
of the corporation, subject to certain limitations.
 
  For example, the corporation shall not so indemnify any person made a party
to any proceeding by reason of the fact that he, or the person whose legal
representative he is, is or was a shareholder, director, officer, employee or
agent of the corporation, unless (1) such person, and the person whose legal
representative he is, was successful on the merits in the defense of any
proceeding referred to in Section 33-320a, or (2) it shall be concluded as
provided in subsection (d) of Section 33-320a that such person, and the person
whose legal representative he is, acted in good faith and in a manner he
reasonably believed to be in the best interests of the corporation or, in the
case of a person serving as a fiduciary of an employee benefit plan or trust,
either in the best interests of the corporation or in the best interest of the
participants and beneficiaries of such employee benefit plan or trust and
consistent with the provisions of such employee benefit plan or trust and,
with respect to any criminal action or proceeding, that he had no reasonable
cause to believe his conduct was unlawful, or (3) the court, on application as
provided in subsection (e) of Section 33-320a shall have determined that in
view of all the circumstances such person is fairly and reasonably entitled to
be indemnified and then for such amount as the court shall determine; except
that in connection with an alleged claim based upon his purchase or sale of
securities of the corporation or of another enterprise, which he serves or
served at the request of the corporation, the corporation shall only indemnify
such person after the court shall have determined on application as provided
in subsection (e) of Section 33-320a, that in view of all the circumstances
such person is fairly and reasonably entitled to be indemnified, and then for
such amount as the court shall determine. The termination of any proceeding by
judgment, order settlement, conviction or upon a plea of nolo contendere or
its equivalent shall not, of itself create a presumption that the person did
not act in good faith or in a manner which he did not reasonably believe to be
in the best interests of the corporation of the participants and beneficiaries
of such employee benefit plan or trust and consistent with the provisions of
such employee benefit plan or trust, or, with respect to any criminal action
or proceeding that he had reasonable cause to believe that this conduct was
unlawful.
 
  Except as otherwise provided in Section 33-320a, a corporation shall
indemnify any person made a party to any proceeding, by or in the right of the
corporation, to procure a judgment in its favor by reason of the fact that he,
or the person whose legal representative he is, is or was a shareholder,
director, officer, employee or agent of the corporation, or an eligible
outside party, against reasonable expenses actually incurred by him in
connection
 
                                     II-1
<PAGE>
 
with such proceeding in relation to matters as to which such person, or the
person whose legal representative he is, is finally adjudged not to have
breached his duty to the corporation, or where the court, on application as
provided in subsection (e) of Section 33-320a shall have determined that in
view of all the circumstances such person is fairly and reasonably entitled to
be indemnified, and that for such amounts the court shall determine. The
corporation shall not so indemnify any such person for amounts paid to the
corporation, to a plaintiff or to counsel for a plaintiff in settling or
otherwise disposing of a proceeding, with or without court approval; or for
expenses incurred in defending a proceeding which is settled or otherwise
disposed of without court approval.
 
  The Certificate of Incorporation of the Company includes a provision
limiting the personal liability of a director to the Company or its
shareholders for monetary damages for breach of duty as a director, to an
amount equal to the amount of compensation received by the Director for
serving the Company during the calendar year in which the violation occurred,
subject to a number of exceptions, including violations involving a knowing
and culpable violation of law, a breach of duty which enables a director or an
associate to receive an improper personal gain, conduct showing a lack of good
faith and conscious disregard of duty to the Company, a sustained and
unexcused pattern of inattention, or the approval of an illegal distribution
of assets of the Company to its shareholders. An associate of a director, in
terms of improper personal gains, is defined as (A) any corporation or
organization of which a Company director is an officer or partner or is,
directly or indirectly, the beneficial owner of ten percent or more of any
class of voting stock, (B) any trust or other estate in which a Company
director has at least ten percent beneficial interest or as to which a Company
director serves as trustee or in a similar fiduciary capacity and (C) any
relative or spouse of a Company director, or any relative of such spouse who
has the same name as the Company director. In addition, the Company also
maintains a directors' and officers' insurance and reimbursement policy.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
  Described below is information regarding all unregistered securities of the
Company sold by the Company within the last three years.
 
  (a) In December 1993, prior to the commencement of its operations, the
Company issued 300 shares of its original Common Stock (now 405,000 shares of
Common Stock) to three individuals who participated in the organization of the
Company for aggregate consideration of $300.
 
  (b) In January 1994, the Company issued $200,030 of 8.00% Convertible
Subordinated Debentures (the "Series I Debentures") to five individuals, four
of whom were directors of the Company. The Series I Debentures bore an
interest rate of 8% (excluding debt discount), compounded annually, and, in
September 1994, were converted into shares of the Company's Series A
Convertible Voting Preferred Stock ("Series A Preferred Stock") at the rate of
one share of Series A Preferred Stock for each $5 principal amount of Series I
Debentures.
 
  (c) In August 1994, the Company issued an additional $160,000 of 8.00%
Convertible Subordinated Debentures (the "Series II Debentures") to two
individuals, under the same terms as the Series I Debentures. In September
1994, all Series II Debentures were also converted into shares of Series A
Preferred Stock at the rate of one share of Series A Preferred Stock for each
$5 principal amount of Series II Debentures.
 
  (d) In February 1995, the Company completed an offering of Series A
Preferred Stock resulting in the issuance of 250,000 shares of Series A
Preferred Stock for aggregate gross proceeds of $1,250,000 or $5 per share.
Knickerbocker Securities, Inc. served as placement agent with respect to this
offering and received commissions in the amount of $105,705 of such gross
proceeds and warrants to purchase an aggregate of 23,500 shares of Series A
Preferred Stock at an exercise price of $5.50 per share.
 
  In connection with the offering described in the within Prospectus, all
outstanding shares of Series A Preferred Stock will be automatically converted
into shares of Common Stock at the rate of 4.2 shares of Common Stock for each
share of Series A Preferred Stock upon the effective date of this Registration
Statement and such warrants to purchase shares of Series A Preferred Stock
will become warrants to purchase an aggregate of 98,700 shares of Common Stock
at a price of $1.31 per share.
 
                                     II-2
<PAGE>
 
  (e) In October 1995, the Company completed an offering of Series III
Debentures maturing in two years with interest at the annual rate of 8.00%.
The Series III Debentures are convertible into Common Stock at the rate of
$3.67 per share, together with accrued interest thereon, and all such
Debentures and accrued interest thereon will be converted automatically into
Common Stock at such rate upon the closing of the offering described in the
within Prospectus. An aggregate of approximately $1.9 million in principal
amount of Series III Debentures were sold through Knickerbocker Securities,
Inc., as placement agent, which received commissions in the amount of $275,000
and a warrant to purchase 15,000 shares of the Company's Common Stock at a
price of $3.67 per share. Each purchaser of a Series III Debenture also
received a warrant to purchase a number of shares of Common Stock equal to the
principal amount of such Debenture divided by $3.67, subject to adjustment.
Such warrants are exercisable for a period of two years, however, in order to
induce earlier exercise, the Company offered the holders of such warrants the
opportunity to exercise their warrants at a reduced price of $2.33 per share
for a limited period in December 1995, and warrants were exercised in response
to such offer with respect to 297,840 shares of Common Stock for proceeds to
the Company in the aggregate amount of $694,960.
 
  (f) In February 1996, the Company issued 8.00% Subordinated Debentures (the
"Series IV Debentures") to two individuals. The Series IV Debentures had a
term of six months with interest at the annual rate of 8.00% per annum
(excluding debt discount) and were repaid in August 1996. Each holder of
Series IV Debentures also received a warrant to purchase shares of Common
Stock in an amount equal to the face value of his Series IV Debenture divided
by $3.67, subject to adjustment at an exercise price per share of $3.67. The
Company received gross proceeds from the sale of Series IV Debentures in the
amount of $405,000.
 
  (g) In March 1996, the Company entered into a loan facility with Xerox
Corporation pursuant to which Xerox may lend the Company up to $3,000,000. The
outstanding principal balance of such loan as of the date of this Registration
Statement is $2,350,000. In connection with this facility, Xerox Corporation
received a warrant to purchase 375,000 shares of Common Stock at an exercise
price of $3.67 per share, subject to adjustment, during a period of 3 years.
 
  (h) In June 1996, the Company completed an offering of 2,625,000 shares of
Common Stock for gross proceeds of $10,500,000 or $4.00 per share.
Pennsylvania Merchant Group Ltd. served as placement agent with respect to
such offering and received commissions of $840,000. In addition, the Company
issued warrants to Pennsylvania Merchant Group Ltd. entitling it to purchase
131,250 shares of Common Stock for a period of five years at an exercise price
of $4.00 per share. The Company issued an additional warrant for 168,750
shares of its Common Stock to Pennsylvania Merchant Group Ltd. in relation to
the termination of these agreements in 1996.
 
  (i) In October 1996, the Company completed an offering of discounted notes
in the aggregate principal amount of $3.45 million bearing interest at 8.70%
per annum (excluding debt discount) with warrants to purchase 45,000 shares of
Common Stock for gross proceeds of $3.0 million. Pennsylvania Merchant Group
Ltd., served as placement agent for this offering and received commissions of
$195,000.
 
  (j) Pursuant to the Company's 1995 Stock Incentive Plan, options have been
issued to purchase an aggregate of 1,293,600 shares of Common Stock of the
Corporation at exercise prices ranging from $1.19 to $4.00 per share.
 
  Exemption from registration pursuant to the registration requirements under
the Securities Act of 1933, as amended, with respect to each of the
transactions described in the preceding paragraphs is claimed pursuant to
Section 4(2) of the Securities Act of 1933, as amended and Regulation D and
Rule 701 promulgated thereunder. In addition, exemption with respect to the
offer and sale of certain Series I Debentures described in paragraph (a)
above, Series II Debentures described in paragraph (b) and Series IV
Debentures described in paragraph (f) above is claimed pursuant to Regulation
S under such Act.
 
                                     II-3
<PAGE>
 
  The Company is relying upon the following facts with respect to the
availability of such exemptions:
 
  The transactions described in paragraphs (a) through (i) above involve the
  issuance of securities to persons which the Company believed, in each case,
  to be "accredited investors" as defined in Rule 501 of Regulation D under
  the Securities Act of 1933, as amended. The transactions described in
  paragraphs (a), (b) and (f) involved the issuance of debt securities, with
  Common Stock purchase warrants, to directors of the Company and one other
  person associated with one of the Company's directors. Such director and
  his associate are non-US citizens, as certified to the Company and they
  were the only participants in the transactions described in paragraphs (b)
  and (f) above. The transactions described in paragraphs (c), (d) and (h)
  above were conducted in accordance with Rule 506 of Regulation D under the
  Securities Act of 1933, as amended. The transactions described in paragraph
  (j) above involve full-time employees, non-employee directors and
  consultants and advisors to the Company and were compensatory in nature.

  Insofar as indemnification for liability arising under the Securities Act of
1933 may be permitted to Directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a Director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such Director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Act and will be governed by
the final adjudication of such issue.
 
  The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

2.01 (a) ACS shall, unless otherwise agreed in writing, at its sole expense use
     all commercially reasonable efforts to develop the ACS 135 Spot Printer to
     conform to the Specifications of Exhibit A and timely complete the
     deliverables, and achieve the milestones and program schedule, set forth in
     Exhibit B hereto.  The Specifications with respect to enabling the ACS 135
     Spot Printer to be interoperable and compatible with the Xerox 4635 and
     4890 Printers must be finalized by February 15, 1996.  The Specifications
     with respect to enabling the ACS 135 Spot Printer to be interoperable and
     compatible with the Docutech will be finalized as soon as practicable after
     the Effective Date.
<PAGE>
 
     (b) ACS shall provide Xerox with progress reports, in accordance with the
     schedule set forth in Exhibit B hereto.  Each such report shall
     reflect/indicate:

     i.     Status of progress to current date/milestone;
     ii.    Short description of problems in meeting such milestones;
     iii.   Proposed recovery method to meet next milestone, if needed;
     iv.    Probability of meeting next milestone.

The parties agree to conduct regular program reviews as shown on the program
schedule to ensure their mutual satisfaction with the performance of the
development work.  In addition, upon reasonable notice, the parties agree to
mutually agreeable times and locations to discuss and inspect the status of the
development work.  The schedule for developing the ACS 135 Spot Printer to be
interoperable and compatible with the Docutech will be finalized as soon as
reasonably practicable after the Effective Date.

2.02 The parties will jointly develop in accordance with the milestones set
     forth in Exhibit B a SCSI II interface specification which shall also form
     part of the Specifications.

2.03 Xerox reserves the right to request in writing changes to the
     Specifications at any time prior to delivery of the ACS 135 Spot Printer or
     other Products to be developed hereunder by ACS.  If ACS reasonably
     determines that such changes are feasible, the parties will agree to such
     changes in writing and ACS will develop the ACS 135 Spot Printer or other
     products to be developed hereunder by ACS to conform to such modified
     Specification and to be delivered in accordance with any modified
     milestones.  Xerox and ACS agree to negotiate in good faith an equitable
     adjustment in Products prices or time schedule, as necessary, for all
     changes to the Specification and ACS shall not be required to continue with
     the development of the ACS 135 or other Products to be developed hereunder
     by ACS until such adjustment is agreed to.

2.04 (a) ACS shall timely deliver to Xerox both the Alpha Software Development
     units and up to ten (10) BO units for testing and acceptance by Xerox.  The
     Alpha Software Development unit shall be a unit sufficiently developed to
     enable Xerox to ascertain if the ACS 135 Spot Printer or any other Products
     to be developed hereunder win be capable of 
<PAGE>
 
     meeting the Specifications, and the manufacturing cost targets, although
     such Alpha Software Development unit may not be fully functional or
     manufactured with actual production tooling The BO units shall be completed
     units with all required functionality and performance for final product
     test purposes. ACS shall sell Xerox up to ten (10) of the initial BO units
     of the ACS 135 Spot Printer or other printer to be developed hereunder by
     ACS at a price of one hundred fifty thousand ($150,000) dollars per unit.
     Delivery will be F.O.B. ACS' manufacturing facility. With respect to such
     BO units Xerox will pay ACS fifty (50%) percent of the applicable purchase
     price contemporaneously with Xerox' order for such units, fifty (50%)
     percent upon delivery.

(b)  ACS shall supply Xerox preliminary data on the On Going Maintenance Rate
     ("OGMR") and Mean Time To Repair ("MTTR") for the ACS 135 Spot Printer or
     other printers distributed hereunder by Xerox/Xerox Affiliated Companies as
     soon as practical 3 in their development cycle. Final OGMR and MT-FR data
     shall be provided as soon as design maturity of such printers is
     demonstrated but in no case later than thirty(30) days prior to general
     availability of the printers. Such OGMR data shall include failure data on
     all major subassemblies of such printers. Further, should any revisions or
     modifications to such printers or component parts thereof affect the OGMR
     or MTTR of such printers, ACS shall supply revised OGMR and MTTR data
     within thirty (30) days of such revisions or modifications.

(c)  In the event that a variance should occur such that the actual OGMR is
     worse than the OGMR specified in Exhibit A , ACS will implement a
     corrective action program at its sole expense acceptable to Xerox to
     correct such variance. If the average OGMR for the ACS 135 Spot Printer or
     other printers distributed hereunder by Xerox/Xerox Affiliated Companies
     nonetheless remains worse than that specified in Exhibit A after such
     corrective action is implemented., ACS agrees to implement a superior
     corrective action program and repair all such printers failed and affected
     Spares at no cost to Xerox. Should such corrective actions taken by ACS not
     result in average OGMR's in accordance with the Specifications, ACS shall
     replace all such printers with a printer that meets or exceeds the
     Specifications, including OGMR'S, at no cost to Xerox.

2.05 After delivery by ACS of any deliverable for which testing for compliance
     with the Specifications is feasible and reasonable, Xerox will test the
     same 
<PAGE>
 
     and notify ACS in writing of either its approval or reasons for its
     rejection of the deliverable due to its nonconformance to the
     Specifications and/or its containing program errors or otherwise not
     functioning properly as soon as reasonably practicable but in no event
     later than thirty (30) days after commencement of such testing.

2.06 Following receipt by ACS of Xerox' written notice of rejection under
     Section 2.05 hereof, ACS will develop within [*] a mutually agreeable
     corrective action plan. If ACS subsequently delivers a corrected
     deliverable to Xerox within said plan corrective period, Xerox will have up
     to an additional [*] from receipt to reevaluate the corrected deliverable.

2.07 If, with respect to any particular ACS deliverable, ACS is unable due to
     ACS' own fault to meet the agreed-upon Specifications and/or eliminate any
     program errors and/or otherwise not provide a properly functioning
     deliverable within the correction period set forth in Section 2.06 above,
     or fails to meet any agreed upon milestone or date for delivery of a
     deliverable then, in addition to any other rights Xerox may have hereunder
     or under applicable law, Xerox may:

(a) extend the correction period by an amount of time as may be determined by
    Xerox; or

(b) approve the deliverable with an equitable reduction in any Products'
    purchase price as mutually determined by Xerox and ACS; or

(c) elect to complete or have completed on its behalf at Xerox' expense the
    nonconforming deliverable and ACS shall give Xerox and Xerox Affiliated
    Companies all reasonable and necessary cooperation with respect thereto at
    ACS' expense including but not limited to (i) helping Xerox and Xerox
    Affiliated Companies procure consumables, parts, components, or
    subassemblies from ACS' vendors, (ii) granting Xerox and Xerox Affiliated
    Companies a world-wide, royalty-free, non-exclusive, irrevocable right to
    use, and sublicense, any ACS intellectual property, including know-how, and

    necessary licenses from third parties necessary for the completion of such
    nonconforming deliverable. Provided, however, within thirty (30) days after
    Xerox elects to exercise the rights granted to it in this subparagraph, it
    shall meet with ACS and discuss in good faith the possibility of ACS
    reacquiring the right to complete in whole or in part the deliverables due
    under this Agreement. In the event Xerox employees or contractors create or
    conceive of any ideas, discoveries, innovations, and inventions
    ("Improvements") in the course of completing the nonconforming deliverable,
    Xerox will own such Improvement and will grant ACS a world-wide , non-
    exclusive, royalty-free, irrevocable right to use such Improvements in
    connection with manufacturing Products hereunder solely for Xerox and Xerox

     ----------                                                             
     laws, regulations and other safety requirements and governmental or other
     agency certifications or approvals required for marketing of the Products
     which are set forth in the Specifications.

                          IV.  PURCHASE AND SALE

4.01 Purchase and Sale - Xerox and Xerox Affiliated Companies may purchase from
     -----------------                                                         
     ACS and ACS shall sell to Xerox and Xerox Affiliated Companies pursuant to
     this Agreement, the Products as are listed in Exhibit C for resale and
     servicing by Xerox, Xerox Affiliated Companies, and/or their respective
     authorized resellers in the Territory.

4.02 Prices
     ------

     (a) Prices for the initial version of Products shall be those set forth in
     Exhibit C hereto. As of the Effective Date, Exhibit C reflects only ACS'
     maximum initial prices to Xerox respecting the purchase of Products.
     Exhibit C will be completed no later than March 15, 1996. Prices for
     Products shall include the cost of packaging and packing which conform to
     the agreed packaging specifications.

     (b)  Xerox may ask ACS for a downward price correction whenever, in
     Xerox' considered opinion, the prices of the Products are, or have become,
     so high compared to similar products marketed by third party competitors or
     by Xerox or Xerox Affiliated Companies, such that Xerox or Xerox Affiliated
     Companies are no longer in a position to compete normally in the
     marketplace.  ACS agrees to negotiate any such request in good faith with
     Xerox, provided that until such time as agreement on any price decrease is
     reached, the prices then in effect shall prevail.

     (c)  If ACS' costs of materials for Products unexpectedly increase and, on
     a cumulative basis, increases the materials component of Products' unit
     manufacturing cost by more than ten (10%) percent in any twelve month
<PAGE>
 
     period ACS may increase Products prices to reflect one-half of such
     unexpected increased cost of materials.

     (d)  In addition, either party may request a change in the price of
     Products hereunder based upon changes in costs or market conditions then
     prevailing, and the parties agree to negotiate such requested price change
     in good faith, and until such time as an agreement on any changed price is
     reached, the prices then in effect shall prevail.

     (e)  ACS shall make all commercially reasonable efforts to reduce year
     over year its costs of manufacturing, selling, and delivering the Products
     to Xerox and Xerox Affiliated Companies by at least eight (8%) percent.
     ACS agrees to pass along to Xerox and Xerox Affiliated Companies one-half
     of such cost reductions in the form of Products prices decreases.

     (f)  The applicable price for Products shall be the price in effect as of
     the date an order for Products is submitted to ACS.

4.03 Trademarks of Products - Xerox intends to market the ACS 135 Spot Printer
     ----------------------                                                   
     bearing the trademarks, trades dress and logos of Xerox and Xerox
     Affiliated Companies, as appropriate.  However, if doing so will cause the
     date of the ACS 135 Spot Printer's initial availability for customer
     deliveries to be significantly negatively impacted, Xerox will agree to
     initially market the ACS 135 Spot Printer bearing ACS' trademarks, trade
     dress, and logos.

4.04 Most Favored Nation Pricing
     ---------------------------

     (a) ACS represents and warrants that the prices for the Products offered to
         Xerox and Xerox Affiliated Companies will be no higher than those
         offered to any other reseller of the Products [*].

     (b) ACS agrees that to the extent the prices offered to Xerox/Xerox


[*] OMITTED INFORMATION SUBJECT TO PENDING CONFIDENTIAL TREATMENT REQUEST
<PAGE>
 
     Affiliated Companies for Products or any other ACS products distributed
     hereunder by Xerox/Xerox Affiliated Companies are higher than those offered
     by ACS to any competitor of Xerox/Xerox Affiliated Companies respecting
     other ACS products, including related spares and consumables, such price
     difference will merely reflect any differing methods employed by ACS in
     manufacturing, selling, or delivering such products for Xerox as compared
     to such other resellers.  In the event ACS is in breach of the foregoing
     such lower prices will apply to Xerox/Xerox Affiliated Companies purchases
     of Products from the date such lower prices were offered to such other

       shall continue for a period of thirty-six (36) months ("Initial Term"),
       and shall be automatically renewed for successive twelve (12) month terms

       the other that the notifying party does not wish this Agreement to be
       renewed.

11.02 Termination for Cause
      ---------------------

      (a) Either party may terminate this Agreement:

          i.  immediately upon written notice if the other party materially
              breaches this Agreement and such breach is not curable or, thirty
              (30) days after written notice of breach if the other party
              materially breaches this Agreement and such breach is curable but
              is not cured within such 30 day notice period (or such other cure
              period as is provided under this Agreement) or,



         ii.  immediately upon written notice if the other party is subject to
              a force majeure condition for more than ninety (90) consecutive
              days and during such time period does not arrange for alternative,
              comparable performance, or

        iii.  if a petition for relief under the applicable bankruptcy
              regulations is filed by or against the other party, or the other

              applicable law prevents the non breaching party from terminating
              this Agreement as described herein, then the parties shall have
              only those rights and remedies permitted by applicable law.
              Termination rights for the specified causes shall exist for a
              period of ninety (90) days after the occurrence of each such
              cause.
<PAGE>
 
(b) Xerox may terminate this Agreement immediately upon written notice if any of
    the Exhibits which this Agreement provides will be completed after the
    Effective Date are not completed by the date set forth herein for
    completion.

11.03  Manufacturing License - In addition to any other rights arising under

       this Agreement or under applicable law which Xerox may have due to ACS'
       material breach of this Agreement, Xerox may elect to manufacture or have
       the Products manufactured and in such event ACS hereby grants Xerox and
       Xerox Affiliated Companies the non-exclusive world-wide irrevocable right
       to manufacture or have the Products manufactured and to use and sub-
       license, in connection with manufacturing the Products, any ACS
       intellectual property, including know-how and related Documentation,
       which is necessary for the manufacture of the Products. In addition, ACS
       shall assign to Xerox all agreements with ACS' vendors to the extent such
       agreements are assignable by ACS and ACS shall give Xerox all reasonable
       cooperation respecting Xerox being assigned the rest of ACS' agreements
       with its vendors. While any amount of the principle and interest subject
       to the Loan Agreement and Promissory Note are outstanding, the foregoing
       license shall be royalty-free. After the aforementioned principle and
       interest is completely repaid the foregoing license shall be subject to a
       royalty of five percent (5%) of then applicable ACS 135 Spot Printer
       price as set forth in Exhibit C. The fact that Xerox exercises the
       manufacturing rights granted to it under this subparagraph shall serve to

       breach of this Agreement by ACS if there remains outstanding and unpaid
       more than one-third of the original principal payable by ACS under the
       Loan Agreement and Promissory Note. A breach by ACS of this Agreement
       respecting the critical milestones identified in Exhibit B hereto shall
       be deemed a material, breach of the Loan Agreement and Promissory Note
       and the Security Agreement.

26.01 The parties shall attempt in good faith to resolve any dispute arising out
      of or relating to this Agreement promptly by negotiations, as follows. Any
      party may give the other party written notice of any dispute not resolved
      in the normal course of business. Executives of both parties at levels one
      step above the project personnel who have previously been involved in the
      dispute shall meet at a mutually acceptable time and place within 10 days
      after delivery of such notice, and thereafter as often as they reasonably
      deem necessary, to exchange relevant information and to attempt to resolve
      the dispute. All negotiations pursuant to this clause are confidential and
      shall be treated as compromise and settlement negotiations for purposes of
      the Federal Rules of Evidence and state rules of evidence. Each party
      shall bear its own expenses.

If the parties are unable to resolve the dispute by negotiations as set forth
above and at least 60 days have elapsed since notice was given, such dispute
shall be settled by arbitration, conducted on a confidential basis, under the
then current Commercial Arbitration Rules of the American Arbitration
Association ("the Association") strictly in accordance with the terms of this
Agreement and the substantive law of the State of New York.  The arbitration
shall be held at a mutually agreeable location in Stamford, Connecticut and
conducted by one arbitrator chosen from a list of attorneys who are members of
the Association's commercial arbitration panel and are knowledgeable about the
semiconductor and business equipment industries.  If the parties cannot
promptly, within thirty (30) days, agree on the selection of the arbitrator, the
arbitrator will be chosen pursuant to Rules 13 of the Commercial Arbitration
Rules of the Association.  The costs of the arbitration, including the fees to
be paid to the arbitrator, shall be shared equally by the parties to the
dispute.  The parties to the dispute shall be limited to taking no more than
three (3) depositions each.  The length of each deposition shall be limited to
one (1) day.  No interrogatories shall be permitted.  The arbitration shall be
completed within six (6) months from the date of the selection 
<PAGE>
 
of the arbitrator. The scope of document production shall be governed by the
commercial Arbitration Rules of the Association and the decision of the
arbitrator with respect thereto. The Judgment upon the award rendered by the
arbitrator may be entered and enforced in any court of competent jurisdiction.
Neither party shall be precluded hereby from seeking provisional remedies in the
courts of any jurisdiction including, but not limited to, temporary restraining
orders and preliminary injunctions, to protect its rights and interest, but such
shall not be sought as a means to avoid or stay arbitration. The arbitrator is
not empowered to award any consequential, incidental, punitive, or exemplary
damages. The parties acknowledge that they have voluntarily agreed to arbitrate
their disputes in accordance with the foregoing and each party hereby
irrevocably waives any damages in excess of compensatory damages.

                             XXVII.  NONPUBLICITY

<PAGE>
 
The manufacturing/quality/test processes must be described to the extent
necessary to assure that defects are detected and removed at the earliest
practical point.


4.0 DEFECTIVE PRODUCTS OR SPARE PARTS


When IBM notifies ACS of defective Product and Spare Parts it has received from
ACS, ACS shall perform a defect analysis and define appropriate corrective
action and communicate it to IBM within four (4) working days.  IBM will be
required to accept or reject the submitted corrective action within four (4)
working days of the receiving the plan.  If IBM has not accepted or rejected the
plan within the four (4) day period, the corrective action shall be considered
accepted.


5.0 DATA RECORDS

ACS is responsible for collection of data and summary reports as mutually agreed
to by ACS and IBM.  ACS's quality data shall be kept for a minimum of three (3)
years.  IBM shall have the opportunity to review quality data upon request.  IBM
reserves the right to ask ACS what kinds of failure analysis and/or corrective
actions are being taken to improve the Product and Spare Parts or processes
and/or eliminate defects.


6.0 HARDWARE ERRORS

IBM defines a hardware Error as any nonconformity that would prompt a service
call being reported by IBM and/or End User. The following nonexclusive list
serves as examples of hardware defects:

7.0 AUDIT INSPECTIONS

7.1 Location of Audits

IBM/ACS Product Purchase Agreement       Page 137                 April 11, 1996
<PAGE>
 
IBM reserves the right to audit Product and Spare Parts from a
manufacturing/quality/reliability standpoint. The audit inspection may be
performed at any one of the two (2) following locations:

a)    At ACS's point of manufacture: This would be done with prior agreement
      with ACS so as to keep the disruption of the manufacturing line to a
      minimum.  ACS will provide the appropriate space, tools, equipment and
      personnel to aid IBM in the audit.  Each party will be responsible for its
      own expenses.

b)    At IBM's distribution center(s): IBM reserves the right to audit the
      Product and Spare Parts at IBM's distribution center(s).  ACS will provide
      the necessary drawings required by an IBM quality inspector to enable this
      inspector to determine the quality level of Products or Spare Parts.


7.2 Audit Findings

After completion of the audit, IBM and the ACS will jointly agree to the
disposition of the Product and Spare Parts based on the findings of the audit.


7.3 Corrective Action

If defects are found in the quality audit, ACS agrees to perform failure and
process analysis and initiate positive corrective action.  ACS will provide the
necessary parts, documentation and labor to correct the defects on the audited
Product and Spare Parts prior to shipment of such Product and Spare Parts to the
end user.


7.4 IBM Responsibilities

IBM quality assurance audit activities will be in progress throughout the term
of this Agreement. These activities in no way replace ACS's quality assurance
efforts.


8.0 SUPPLIER EVALUATION

8.1 Supplier Audits

IBM reserves the fight to conduct preliminary and periodic audits to assure that
ACS's and/or ACS's subcontractors facilities, manufacturing and quality
assurance programs are adequate for production of the Product and Spare Parts to
meet the Product and Spare Parts Specifications.  Audits of ACS suppliers by IBM
must be agreed to and coordinated by ACS to ensure minimal interruption to ACS
suppliers.


8.2 Audit Personnel

IBM/ACS Product Purchase Agreement      Page 138                 April 11, 1996
<PAGE>
 
IBM may assign a resident representative to ACS's facility to perform source
audits. Appropriate notification will be given to ACS of this intent.


9.0 Product and Spare Parts PERFORMANCE

9.1 General


IBM will periodically provide ACS with summary defect data.  The period the data
will cover will be established by the parties, as needed, to ensure defect free
Product and Spare Parts.  The data provided will be the combined results of
incoming quality audits, any defect discovered during prove integration into IBM
process and field repair audits.

The parties shall meet at least one (1) time each calendar quarter to review
this data, defect trends and any corrective actions that were implemented or
need to be implemented to eliminate defects.



9.2 Installation

IBM expects that Product and Spare Parts will be installed by IBM's Customer
Engineering force in the field defect free. The goal for the three (3) month
rolling average for install will be at least 97% defect free.


9.3 Early Life

IBM expects that the Product and Spare Parts will perform in the field (at the
End User location) without failure.  The goal for the three month rolling
average for early life failures will be jointly determined by IBM and ACS.


9.4 Full Field

IBM expects that the Product and Spare Parts will perform in the field (at the
End User location) without failure.  The goal for the three month rolling
average for full field defects will be jointly determined by IBM and ACS.


9.5 Remedies

If the Product and Spare Part fails to meet the above quality/reliability
requirements for the install, early life or full field, IBM and ACS agree to
perform failure/process analysis and provide positive corrective actions. Such
corrective actions may require actions by IBM, ACS, or both parties. If it is
determined that ACS is the cause of the failure to meet the above
quality/reliability requirements, ACS shall issue Engineering Changes as defined
in Section 8 "PRODUCT CHANGES" of this Agreement, to remedy the cause of the
failure.  Other actions may be required to remedy such failures and will be
negotiated on an event by event basis and mutually agreed to by the parties.

("new D") goal for Spare Parts supplied by ACS to IBM shall be 3% or less.  The
"new D" rate will be reported by IBM's quality engineer to ACS on a monthly
basis.


10.2 Defective Spare Parts Return

IBM agrees to have defective or rejected Spare Parts returned from IBM's
Customer Engineering Force in the field.  IBM will then return these parts to
ACS for failure analysis and corrective action when agreed upon by IBM and ACS.


10.3 Remedies

If ACS fails to meet the above quality/reliability requirement for Spare Parts,
ACS agrees to perform failure/process analysis and provide positive corrective
action.  Upon mutual agreement, ACS will provide the necessary parts,
documentation and labor to correct the problem at ACS's repair facility or
reimburse IBM for the same.  IBM reserves the fight to return all suspect Spare
Parts from IBM's Spare Parts distribution network for repair/replacement by ACS.


11.0 NONCONFORMING MATERIAL

11.1 Acceptance

Product and Spare Parts not conforming to the specifications required by this
agreement are not acceptable for shipment to IBM except when an off-
specification (off-spec) request has been made by ACS and approved by IBM's
manufacturing or quality engineer.  Off-specs will not be considered for safety
or functional defects.


11.2 Disposal

Procedures are required by ACS to identify, evaluate, control and dispose of 
non-conforming material. Such material must be segregated to prevent
contamination of production lots.

Graphics Requirements
  -  Naming conventions for graphics files (using C6PaOnnn prefix):
  -  C6POOnnn.pcx - graphic files in Operator's Guide
  -  C6PMOnnn.pcx - graphic files in Maintenance Information
  -  C6PPOnnn.pcx - graphic files in Part's Catalog
  -  PC directory structure for graphics files:
     -  c:\3991\art\main\filename.pcx
     -  c:\3991\art\oper\filename.pcx
  -  Create source art as vector graphics (not bit map) at 300 dpi
  -  File format for source art must be either CGM, CDR, Al, or DXF
  -  Size the source art (rather than when importing into Frame)
  -  Create PCX files from source graphic using HiJack, if necessary
  -  Import all graphics by reference at 300 dpi into the text files
  -  Graphic label Requirements-.
  -  For Maintenance Information, use callouts (reverse type) in graphics
     rather than text labels.
  -  For customer documents, create graphics without labels and add labels to
     the graphic after the graphic is imported.
  -  Place filename for graphic (outside graphic, rotated, 6 point)


The content outline for the Operator's Guide list in item #1 above, will be
similar to the IBM 3900 printing system as approved by both ACS and IBM.

The following are requirements for the Maintenance Information in item #2 above:

Maintenance documentation package is to contain the following tabbed sections:
   - Safety
   - Locations
   - Wiring diagrams
   - PM, (Preventive Maintenance)
   - Diagnostics
   - Parts catalog
   - MAPs (Maintenance Analyst Procedures)

FrameMaker does not support MAPs format to be used in the documentation. A list
of all the possible items that could cause a particular problem will be
sufficient. For instance, the drive motor does not run because; motor is
defective, wiring is open, (list all possible open wires), circuit breaker is
open, bind in the driven mechanism, etc.

A list of helpful diagnostics should also be included. For instance, driver
routine that runs the drive motor, driver for routine for motor rotation sensor.
A small wiring diagram should also be included for the circuitry that may be
involved in the failure. See 3900 MAPS for examples.

Business Machines Corporation, located at 6300 Diagonal Highway, Boulder, CO
80301 ("IBM") and Accent Color Sciences, Inc., with a principal place of
business at 101 East River Drive, East Hartford, CT 06108 ("ACS").

WHEREAS, IBM and ACS are exploring the possibility of evaluating and entering
into a contemplated development and procurement relationship; and

WHEREAS, the disclosure of certain information that is confidential to both IBM
and ACS is required in order to further evaluate the feasibility of such a
contemplated development and procurement relationship; and

NOW THEREFORE, both IBM and ACS agree to the following terms and conditions:

1.   For purposes of this Agreement, "Information" shall mean that
     nonconfidential or confidential information pertaining to the possible
     development and/or procurement of a high speed, spot color printer for
     attachment to the IBM 3900 family of printers.

2.   For purposes of this Agreement, "Discloser" shall mean the party to this
     Agreement who is disclosing Information in confidence to the other party to
     this Agreement, in accordance with the terms and conditions of this
     Agreement.

3.   For purposes of this Agreement, "Recipient" shall mean the party to this
     Agreement who is receiving Information in confidence from the other party
     to this Agreement, in accordance with the terms and conditions of this
     Agreement.

4.   For purposes of this Agreement, "Subsidiary" shall mean a corporation,
     company or other entity more than fifty percent (50%) of whose outstanding
     shares or securities (representing the right other than as affected by
     events or default, to vote for the election of directors or other managing
     authority) are, now or hereafter, owned or controlled, directly or
     indirectly, by a party hereto, but such corporation, company or other
     entity shall be deemed to be a Subsidiary only as long as such ownership or
     control exists.

5.   Both IBM and ACS understand and agree that in the event that additional
     Information or information of a more highly sensitive or confidential
     nature needs to be exchanged, a mutually agreed upon amendment to this
     Agreement which governs both the exchange and use of such Information or
     information of a more highly sensitive or confidential nature, will be
     executed by the parties.

6.   All disclosures of Information by Discloser to Recipient pursuant to this
     Agreement shall be made by or under the supervision of a Technical
     Coordinator for Discloser to a Technical Coordinator for Recipient or their
     respective designees, if any, who shall be
<PAGE>
 
     identified in an express writing.  Such Technical Coordinators are
     identified in Paragraph 12 hereof.  All disclosures of Information will be
     deemed to be nonconfidential unless specifically designated at the time of
     disclosure (in the manner described in Paragraph 7 hereof) as including
     confidential Information.  With respect to all such Information disclosed
     by Discloser to Recipient, except such Information as is so designated as
     the confidential Information of Discloser, Discloser grants to Recipient,
     to the extent, if any, of its interest therein, a nonexclusive, royalty
     free, irrevocable, unrestricted, and worldwide license to use, have used,

     and maintenance of products and services incorporating such nonconfidential
     Information.

7.   With respect to such Information of Discloser, when it is disclosed in
     writing (including such Information recorded in a medium such as a tape or
     disk), the writing will state the date of disclosure, that the Information
     contained therein is confidential and that it is being disclosed pursuant
     to this Agreement, and will contain an appropriate legend, such as "IBM
     Confidential Information" or "ACS Confidential Information." If such
     disclosure is orally and/or visually made after the date of execution of
     this Agreement, then the confidential nature of the Information so
     disclosed shall be confirmed in a written resume within twenty (20) days
     following such disclosure.  If such disclosure was orally and/or visually
     made prior to the date of execution of this Agreement, then the
     confidential nature of the Information so disclosed shall be confirmed in a
     written resume within twenty (20) days following execution of this
     Agreement.  The resume will specifically identify that Information which is
     confidential.  Such resume will have such Information which is confidential
     identified as "IBM Confidential Information" or "ACS Confidential
     Information.

     three (3) years from the date of disclosure, the period of confidentiality,
     Recipient agrees to use the same care and discretion to limit disclosure of
     such received confidential Information of Discloser to only those of its
     employees who have a need to know it and to avoid disclosure, publication
     or dissemination of the Information by those Recipient employees, using at
     least the same degree of care as Recipient employs with similar information
     of its own which it does not desire to publish, disclose or disseminate.

Recipient may use any writings or resumes containing any such confidential
Information provided by Discloser for any purpose, subject to the obligation of
confidentiality in the above paragraph.  Recipient shall be free to use the
residuals of such confidential Information of Discloser for any purpose
including use in the development, manufacture, marketing and maintenance of its
products and services.  However, Recipient may not overtly utilize Discloser's
confidential Information or the residuals thereof to develop products similar to
the products developed and/or marketed by Discloser.  Otherwise, any permitted
use hereunder with respect to the residuals of such confidential Information
shall be subject only to the obligations with respect to disclosure of such
confidential Information during such foregoing specified period of
confidentiality. Recipient may make a reasonable number of
<PAGE>
 
copies of any writings or resumes containing Discloser confidential Information
received from Discloser pursuant to this Agreement.

The term "residuals", as used in this Agreement, shall mean that Information in
non-tangible form which may be retained by those employees of Recipient who have
had access to the confidential Information of Discloser during the term of this
Agreement.  It is understood that receipt of Discloser's confidential
Information under this Agreement shall not create any obligation in any way
limiting or restricting the assignment and/or reassignment of Recipient
employees within Recipient.  The obligations respecting the confidentiality of
shall not, however, be affected or changed as a result of any such assignment
and/or reassignment of Recipient employees.

Following the period of confidentiality, no obligation of any kind is assumed
by, or is to implied against, Recipient with respect to any Discloser
confidential Information, and Recipient shall be free to disclose, publish or
disseminate such confidential Information to others without limitation and shall
have all the rights relative to such Information as are set forth in Paragraph 6
hereof as if such confidential Information had been transferred as
nonconfidential Information under said Paragraph.

9.   Disclosure of such confidential Information of Discloser shall not be
     precluded if such disclosure is:

     a)   In response to a valid order of a court or other governmental body of
          the United states or any political subdivision thereof; provided,
          however, that Recipient shall first have given notice to Discloser and
          made a reasonable effort to obtain a protective order requiring that
          the Information and/or documents so disclosed be used only for the
          purposes for which the order was issued; or

     b)   otherwise required by law; or

     c)   necessary to establish rights under this Agreement.

10.  Notwithstanding any other provisions of this Agreement, the obligations
     specified in Paragraph 8 hereof will not apply to any Information that:

     a)   is already in the possession of Recipient or any of its Subsidiaries
          without obligation of confidence;

     c)   is or becomes publicly available without breach of this Agreement;
     d)   is rightfully received by Recipient from a third party;
     e)   is released for disclosure by Discloser with its written consent; or 
          is inherently disclosed in the use, lease, sale or other distribution
          of, or publicly available supporting documentation for, any present or
          future product or service by or for Recipient or any of its
          Subsidiaries.

2.    The parties by signing this Letter Agreement wish to confirm and commit, 
as stated hereinafter, to the various obligations that are set forth herein as 
inducements to enter into the Product Purchase Agreement.

3.    ACS wishes to confirm to IBM its understanding and intention to make 
production units of its web, color printing systems; designed for use in 
combination with the IBM 3900 printing system and improved 3900 printing 
systems, available to IBM in accordance with the terms of the Product Purchase 
Agreement in time for commercial sale by IBM during the third calendar quarter 
of 1996.

4.    ACS confirms its intention to make ACS production units, which may be used
in combination with other, non-IBM web printing systems available for commercial
sale starting June 1, 1997. ACS further confirms that if the first commercial
sales by IBM of ACS' web, color printing systems designed for use in combination
with the IBM 3900 printing system and improved 3900 printing systems are delayed
through the fault of ACS, including the fault of ACS' vendors and suppliers, ACS
confirms that the availability of other, non-IBM web printing systems will be
delayed in equal measure.

5.    ACS is also planning to have units with enhanced printheads available in 
limited quantities by October of 1996.  First priority for the installation of 
these printheads will be given to units with the earliest contract dates; 
specifically the True Color 390 printer for IBM and the True Color 135 printer 
(cut sheet) for others, in equal volumes.  ACS additionally confirms its 
commitment to provide a web, color printing system having enhanced printheads to
IBM for use in combination with a current IBM 3900 model or an improved 3900 
model in time for demonstration at the 1996 Xplor International Printing 
Convention to be held during the fourth quarter of 1996.  It is IBM's 
responsibility to insure that the specific 3900 printing system used at the 
Xplor Convention will work satisfactorily with ACS' web, color printing system 
having enhanced printheads.

6.      In the event that ACS cannot fulfill its commitment to provide a web, 
color printing system having enhanced printheads to IBM for use in combination 
with the IBM 3900 or a then current, improved 3900 printing system in time for 
demonstration at the 1996 Xplor International Printing Convention, then ACS 
agrees to make a fifteen percent (15%) reduction in the price of all production 
units of the then current ACS web, color printing system ordered or accepted by 
IBM up through the fourth quarter of 1996, up to, but not exceeding the larger 
of (a) an aggregate dollar amount of price reduction of two hundred fifty 
thousand dollars ($250,000) or (b) the total amount of advance deposits received
in 1996 by ACS, as of the initial date of Xplor, from IBM against orders of 
production units of the ACS True Color web printer.

7.      ACS further confirms and commits that it will not make web, color 
printing systems having enhanced printheads available for use or demonstration 
in combination with other, non-IBM web, printing systems until after the 1996 
Xplor Convention is completed.

8.      These production introduction schedules are a function of ACS' best 
estimates of the time required for it to meet general availability schedules, 
recognizing that the ACS web color printing system for combination with IBM 3900
products will be available for general market introduction well in advance of 
any other ACS web system combination in view of the substantial IBM lead time 
associated with this effort and the priority which ACS efforts on behalf of IBM 
and IBM efforts on behalf of ACS have been given. Based on a continuation of the
excellent working relationship and effort being made by both IBM and ACS on this
project, ACS is committed to maintaining these delivery schedules in accordance 
with the foregoing commitments.

9.      This Letter Agreement shall become null and void and have no further 
force and effect on the parties if:

        a. the Product Purchase Agreement is not signed by April 15, 1996; or

        b. IBM terminates the Product Purchase Agreement prior to June 1, 1997; 
           or

        c. IBM markets an alternative to the ACS web, color printing system
           designed for use in combination with the IBM 3900 printing system and
           its enhancements prior to June 1, 1997.

8.   LICENSES AND ROYALTIES
     ----------------------

     8.1. Subject to the terms of this Agreement, (i) Spectra hereby grants to
Customer a worldwide right and license, with rights to sublicense only in
connection with Customer Products, under the Spectra System Technology to make,
have made, use and sell Customer Products in Customer's Field an d Customer's
Exclusive Field, and (ii) Customer hereby grants to Spectra a worldwide right
and license, with rights to sublicense only in connection with Spectra products,
under Customer Program Technology to make, have made, use and sell Spectra
Products for resale outside of Customer's Exclusive Field. Except as set forth
in Section 8.5 and 8.6, the license granted Customer herein expressly excludes
the right to manufacture Printheads or Inks.

     8.2  Spectra agrees to indemnify, defend and hold Customer and its
customers harmless from and against any claim against them by Howtek, Hitachi
Koki and Dataproducts, Inc., their affiliates, successors or assigns, that a n y
Customer Print Engine that includes a Spectra Printhead infringes any patents o
f such parties described in Schedule 2. This indemnity will apply only to those
Customer Print Engines including Spectra Printheads purchased from Spectra while
Customer is in good standing with respect to the payment of license fees and
royalties provided for in this Section 8.

     8.3. Customer will pay to Spectra those royalties and license fees set
forth in Schedule 2, "Royalties and License Fees", in connection with purchases
of Hardware in which Customer uses phase change Ink, subject to the terms and
conditions thereof. Customer shall not be obligated to pay royalties or fees 
set  
<PAGE>
 
forth in Part I of Schedule 2 to Spectra in excess of those due from Spectra to
t h e third parties defined in Schedule 2 with respect to Customer's purchases
from Spectra. In the event of a reduction in royalties payable by Spectra to
such third parties, Customer's royalties shall be reduced accordingly. The
royalties set forth in Part 11 of Schedule 2 shall be suspended for so long as
Customer shall be purchasing its requirements of Ink from Spectra.

     8.4. Customer will provide Spectra with a written report, no later than
thirty (30) days following the end of each calendar quarter, describing for such
calendar quarter the number and type of Customer Product and Ink sold, leased or
otherwise disposed of, together with a detailed royalty calculation sufficient
to establish a statement of royalties due under Spectra's agreements with
parties identified in Schedule 2. Customer will pay any royalties due together
with such report.

     8.5  Coverage for Spectra supply risk: Within 60 days of the execution of
this Agreement, Spectra will place in escrow, with a mutually agreed escrow
agent (the charges of such agent to be borne by Customer), full details, to the
extent known to Spectra and promptly updated for material changes by Spectra
from time to time, of the compositions and methods of manufacture of the
Hardware Products and Inks to be supplied by Spectra to Customer. Customer may
inspect such materials prior to placement in escrow by Spectra. The escrow
agreement shall provide that the material to be placed in escrow shall be
available to Customer in the event that:

     a.   a Supply Failure (as defined in this paragraph) shall have occurred.
     In the event that Spectra shall be unable to fill an order for a particular
     Hardware Product or Ink that Spectra is obligated to fill under Section 2.1
     hereunder, Spectra shall so advise Customer as soon as practicable, and
     shall advise Customer of the remedial action that it intends to take. If
     such failure shall continue until twenty (20) days following the agreed
     shipment date, Customer may send personnel to Spectra to observe the
     progress toward correcting such failure to supply and to assist in
     resolving the situation. In the event that such failure shall continue for
     an additional 40 days, then a Supply failure shall be deemed to have
     occurred; or
<PAGE>
 
     b.   Customer acquires and exercises rights under United States Code, Title
     11, Section 365(n)(1)(B) (option for licensee, whose license has been
     rejected by trustee in bankruptcy, to retain rights under the license).

8.6  In connection with Section 8.5:

          8.6.1   It is understood and agreed that if the Supply Failure relates
     only to Hardware Products or Inks, but not both, the information to be
     released from escrow will be only that related to Hardware Products or
     Inks, as appropriate.

     8.6.2  Customer may use escrowed information only to produce or have
produced those Hardware Products and Inks being supplied by Spectra to Customer
immediately prior to the occurrence of the condition giving rise to the release
of escrowed information, as such Hardware Products and Inks existed at the time
of the occurrence of the condition. In the event that a Supply Failure relates
to fewer than all of the models of Hardware Products being supplied by Spectra,
Customer may only manufacture or have manufactured those models of Hardware
Products Spectra failed to supply. Upon the occurrence of the condition in 8.5.a
above with respect to Inks, Spectra shall arrange for supply of Inks to Customer
by a third party at the request of Customer, at the same prices and terms at
which Spectra supplies Customer. Upon the occurrence of the condition in 8.5.b
above with respect to Inks, Customer shall be free to negotiate with Coates
Reprographics, Inc. for the supply of ink directly from Coates to Customer,
notwithstanding any previous agreement involving Spectra, Customer o r Coates
which would otherwise bar the supply of ink directly from Coates to Customer.
Any manufacture by or for Customer of Hardware Products o r Inks, or acquisition
of Inks from Coates, shall be subject to a royalty to Spectra of 10% of the
resale price by Customer of such Hardware Products or Inks.

     8.6.3  It is understood and agreed that Spectra does not have the right to
grant sublicenses for the manufacture of Printheads under its license with
Dataproducts and Hitachi-Koki and, accordingly, any exercise by or for Customer
of the above rights in the event of Supply Failure will require Customer to
obtain a license from them.
<PAGE>
 
9.   DISTRIBUTION RIGHTS AND EXCLUSIVITY

     Customer shall have a cure period of 45 days after any calendar year-end to
make up any purchase deficiencies hereunder and a cure period of 15 days to make
up any payment deficiency hereunder.  In the event Customer fails to make a
<PAGE>
 
payment or payment, under Section 9.2.2, Spectra may terminate the exclusive
rights provided under Section 9.2.1 on forty-five days prior written notice if
Customer shall fail to cure such nonpayment within such forty-five day period:
but in the event of such termination, all other rights and obligations of the
parties under this Agreement shall remain unchanged.

9.2.3.  With respect to any payments received under this section 9.2, Spectra
agrees to use fifty percent (50%) of the such funds for development activities
on Spectra Products for use in Customer Products. It is understood that during
1995 and 1996, such activities shall be focused on modular carbon printhead
development (i.e. the 256 jet printhead family demonstrated to Customer
personnel); the development activities for 1997 shall be as mutually agreed upon
by the Parties.

     9.3  For so long as Customer makes the scheduled payments set forth in
Section 9.2.2. above and all royalty payments required under this Agreement,
Customer shall have the right, to the fullest extent within Spectra's rights,
(I) to purchase from Spectra ink jet products developed, manufactured and sold
by Spectra in the future, provided, however, that Customer may use such products
in Reserved Markets: and (ii) to the license granted Customer in Section 8.1
which shall include a license to Spectra Future System Technology, on the same
terms and subject to all of the conditions of the license set forth in Section
8.1, developed during the period Customer makes such payments. Thereafter
through the initial Term of this Agreement, Customer shall continue to have
rights to subsequent new products and the license in Section 8.1 shall continue
to include Spectra Future System Technology so long as Customer pays to Spectra
a fee of $250,000 at the beginning of each calendar quarter and is current in
all royalties due under this Agreement. In the event that Customer fails to make
a quarterly $250,000 payment after 1998 in accordance with this Section 9.3,
Customer's rights to participate in Spectra Future Systems Technology may be
terminated by Spectra on forty-five days prior written notice, subject to
Customer's right to cure such nonpayment within such forty-five day period; but

<PAGE>

sales proposals, advertising literature, and otherwise, as a Customer or
Affiliate product. Customer may ship those products in containers bearing the
Customer or Affiliate logo, class and serial number of the product, and all
other information or markings desired by Customer or required by law.

10.  CONFIDENTIALITY
     ---------------

     10.1  "Confidential Information" means all information  which one
party ("Discloser") discloses to the other party ("Recipient") during the term
of this Agreement: (I) in documents or other tangible materials clearly marked
"CONFIDENTIAL", or (ii) orally, or in any other intangible form, when first
disclosed to the Recipient, if at that time the Discloser tells the Recipient
that the information is confidential and if the Discloser describes the
information in writing or other tangible materials clearly marked "CONFIDENTIAL"
and delivers them to the Recipient within 10 calendar days after the information
is first disclosed to the Recipient. "Confidential Information" does not include
any information which the Recipient can show: (a) the Recipient knew at the time
o f disclosure, (b) the public knows or which is or becomes readily
ascertainable by the public, and through no wrongful act of the Recipient, (c)
the Recipient receives from a third party without breaching an obligation owed
to the Discloser, if the third party does not restrict the Recipient from
disclosing that information, (d) is independently developed by or for the
Recipient, the Discloser discloses to a third party without similar restrictions
on disclosure, or (e) is required to be disclosed by law, provided, however,
that in the event Recipient is ordered to disclose the Discloser's Confidential
Information pursuant to a judicial or governmental request, requirement or
order, Recipient shall immediately, and in any event prior to complying
therewith, notify the Discloser and take reasonable steps to assist Discloser in
contesting such request, requirement or order o r otherwise protecting
Discloser's rights, and Recipient may not disclose any Discloser Confidential
Information in response to any law, rule or regulation, including disclosure
rules of the Securities and Exchange Commission, without the Discloser's written
consent in each case, which consent shall not be unreasonably withheld or
delayed.

     10.2.  During the Term and for three years after the Term, the Recipient
shall use reasonable efforts to prevent the disclosure of any Confidential
Information to any other person, subject to Section 10.1. All materials
containing Confidential Information delivered by the Discloser under this
Agreement are and shall remain the property of the Discloser.  At the
Discloser's written request upon termination of the Recipient's right to possess
the Discloser's Confidential Information, the Recipient shall promptly return to
the Discloser, or destroy and
<PAGE>
 
certify the destruction of, all those materials and any copies.

     10.3.  Except as this Agreement expressly provides, this Agreement does
not: (i) restrict either party from developing new products, improving existing
products, or marketing any new, improved, or existing products; or (ii) commit
either party to disclose any particular information or to develop, make, use,
buy, sell, or otherwise dispose of any existing or future product, or to favor 
or recommend any product or service of the other party.

     10.4.  This Agreement does not enlarge, diminish, or affect the rights and
obligations that either party may have or come to have under any other written
agreement they both sign, or, except as this Agreement expressly provides, with
respect to any patent or copyright of either party.  Except as this Agreement 
or such other written agreement specifically provides, there shall be no
restrictions on the use or disclosure of any information the parties exchange at
any time, in the past or in the future, other than restrictions that either
party may independently have a right to assert under the patent, copyright, or
mask work laws.

II.  INFRINGEMENT
     ------------

     11.1.  Spectra shall promptly investigate and defend at its expense all
claims that the manufacture, use, maintenance, sale or other disposition of any
Spectra Product infringes, induces the infringement of, or otherwise violates
any patent, copyright, mask work, trademark, trade secret, or proprietary or
other information of any third party, and Spectra shall pay and discharge all
judgments or decrees against Customer which result from those claims.  Spectra
may, with Customer's consent (which Customer shall not unreasonably withhold),
settle any such claim on terms of Spectra's choosing, if those terms do not
conflict with this Agreement; provided, however, that Spectra shall not be
obligated under this Section 11.1 to the extent (i) Customer fails to give
Spectra prompt notice of the claim, appropriate authority to settle or defend
it, or the information and assistance necessary to conduct the defense, or (ii)
the claims of infringement arise from or are based upon (A) Customer's or any
third party's enhancements, modifications, alteration or implementation of a
Spectra Product, or (B) the combination of a Spectra Product with any device
Spectra did not directly furnish to Customer.
<PAGE>
 
     11.2.  If (i) a court, agency, or arbitrator having jurisdiction holds
that, or Spectra agrees in writing with any third party that, any Spectra
Product infringes a patent, copyright, mask work, or trademark or involves an
unlawful use of a third party's proprietary or other information, (ii) an
injunction issues against Customer's manufacturing, use, or marketing of a
Spectra Product, or (iii) in Spectra's opinion that Spectra Product is likely to
become the subject of an infringement claim, then Spectra shall at its expense
use reasonable efforts to: (x) obtain for Customer rights sufficient in scope to
allow Customer to continue to make, use, sell, and market that Spectra Product,
or (y) replace or modify that Spectra Product so that it becomes noninfringing.

     11.3.  Spectra shall not be liable under this Section 11 for any claim, and
Customer's rights under Section 11.2 shall not attach to a claim, to the extent
that claim is based on information, devices, or processed furnished by someone
other than Spectra.

12.  TERM AND TERMINATION: BANKRUPTCY
     --------------------------------

     12.1.  This Agreement is effective on and after the Effective Date and
shall expire seven years after the Effective Date, unless earlier terminated

            12.2.1.  Spectra and Customer may at any time agree in writing
to terminate this Agreement.

            12.2.2.  If Customer fails without cause to pay Spectra any
amount due Spectra, Spectra may terminate this Agreement if Customer does not
cure that failure within 45 days after Customer receives a written notice from
Spectra stating the facts on which Spectra based its determination that such a
failure occurred.

            12.2.3. If either party breaches a material obligation of this
<PAGE>
 
Agreement, and such breach is not cured within 90 days after receipt of the
notice from the non-breaching party, the non-breaching party may terminate this
Agreement.

     12.3.  All financial obligations which had accrued but which were unpaid as
of the effective date of termination shall survive termination. All financial
obligations which would have accrued after the effective date of termination
shall terminate. All then-outstanding forecasts and Purchase Orders shall
terminate without liability or consequence to either party as of the effective
date of termination. All licenses granted to Customer hereunder shall terminate.
The license granted to Spectra in Section 8.1 shall survive termination.

13.  DISPUTES
     --------

     13.1.  Except for disputes concerning Spectra's obligations under Section
11.1, and except as otherwise provided in this Agreement, Customer and Spectra
shall settle by arbitration any controversy or claim between them arising
directly or indirectly under this Agreement, whether based on contract, tort,
fraud, misrepresentation, or other legal theory. The arbitration shall occur in
Massachusetts, under the then current rules and supervision of the American
Arbitration Association. If the dispute involves a claim for money in the amount
of $1,000,000 or less and does not involve any claims relating to ownership,
use, or disclosure of intellectual property (other than a claim of unlawful
ownership, use or disclosure of intellectual property arising solely from a
failure to pay a license fee or royalty), the arbitration shall be before a
single arbitrator whom Customer and Spectra shall select from a panel of persons
knowledgeable in business information and data processing systems; otherwise,
the arbitration shall b e before three arbitrators, one selected by Customer,
one selected by Spectra, and the third selected by the two arbitrators to
selected. The arbitrator or arbitrators shall not have the power to award
punitive or exemplary damages. The decision and award of the arbitrator or
arbitrators shall be final and binding and the award rendered may be entered in
any court having jurisdiction. Customer and Spectra shall each pay its own
attorney's fees associated with the arbitration, and shall pay the other costs
and expenses of the arbitration as the rules of t h e American Arbitration
Association provide.

     13.2.  Spectra and Customer may each petition a court of law for injunctive
relief to protect its respective intellectual property.
<PAGE>
 
     13.3.  Connecticut law shall govern the interpretation and enforcement of
this Agreement, except that the Federal Arbitration Act shall govern the
interpretation and enforcement of Section 13.1. If one party files a court
action alleging claims subject to binding arbitration under Section 13.1, and
the other party successfully stays the court action or compels arbitration of
the claims, or both, the party filing the court action shall pay the other
party's costs and expenses, including attorneys' fees, of obtaining such stay or
compulsion.

     13.4.  Neither Customer nor Spectra may bring any action, regardless of
form, related to this Agreement, more than two years after the cause of action
accrues.

     13.5.  The duty to arbitrate under Section 13.1 extends to any director,
officer, employee, agent, subsidiary, or Affiliate making or defending any claim
which would otherwise be arbitrable.

     13.6.  Each part of this Section 13 is severable. A holding that any part
of this Section is unenforceable shall not affect the duty to arbitrate under
Section 13.1 or any other part of this section.

14.  MISCELLANEOUS
     -------------

     14.1.  EXCEPT TO THE EXTENT OF SPECTRA'S OBLIGATIONS UNDER SECTION 11 OF
THIS AGREEMENT, NEITHER SPECTRA NOR CUSTOMER SHALL BE LIABLE TO THE OTHER FOR
ANY SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION
LOST PROFITS) UNDER THIS AGREEMENT.

     14.2.  Spectra and Customer are contractors independent of one another.
Nothing in this Agreement is intended to or shall constitute either party as a n
agent, legal representative, partner, joint venture, franchisee, employee, or
servant of the other for any purpose. Neither party shall make any contract,
agreement, warranty, or representation on behalf of the other party, or incur
any debt or other obligation in the other party's name, or act in any manner
which has the effect of making that party the apparent agent of the other; and
neither party shall assume liability for, or be deemed liable as a result of,
any such action by the other party. Neither party shall be liable by reason of
any act or omission of the other party in the conduct of its business or for any
resulting claim or judgment, including 
<PAGE>
 
without limitation those arising from oral or written statements the other party
makes in connection with its marketing efforts (other than statements made in
reliance on written information which the first party furnishes to the other
party).

     14.3.  Neither Spectra nor Customer may assign this Agreement or any of
their respective rights and obligations under this Agreement without the express
written consent of the other party before that assignment, except that either
party may without the other's prior consent assign this Agreement to a successor
in ownership of all or substantially all of its assets or the product line that
includes the Customer Products.  Any assignment under this Section 14.3 will not
relieve the assigning party of its outstanding financial obligations, if any,
incurred before the assignment.  This Agreement shall be finding upon and inure
to the benefit of the parties and their respective successors and permitted
assigns.

     14.4.  A waiver of a default of any term of this Agreement shall not be
construed as a waiver of any later default of that provision or as a waiver of
the provision itself.  A party's performance after the other party's default
shall not be construed as a waiver of that default.

     14.5.  Each term of this Agreement is severable.  If a court, agency, or
arbitrator having jurisdiction determines that any term is invalid or
unenforceable under applicable law, that determination shall not affect the
other terms of this Agreement, which other terms shall continue to be enforced
as if the invalid or unenforceable provisions were omitted.

     14.6.  Except as this Agreement otherwise provides, no amendment to this
Agreement shall be binding unless agreed to in writing executed by Spectra and
Customer, and no approval, consent, or waiver shall be enforceable unless signed
by the granting party.  The pre-printed terms of any order (including without
limitation a Purchase Order), acknowledgment, or other form do not amend this
Agreement.  No document shall be deemed to amend this Agreement by implication.

     14.7.  This Agreement (including the attached Exhibits) states the complete
agreement between Spectra and Customer concerning this subject, and supersedes
all earlier oral and written communications between Spectra and Customer
concerning this subject.
<PAGE>

               holders of at least a majority of the outstanding Shares (other
               than Shares which have been previously sold in a public offering)
               to effect the Registration of Registrable Securities, then the
               Company shall promptly give written notice of such proposed
               Registration to all holders of such Shares, and thereupon the
               Company shall promptly use its best efforts to effect the
               Registration of the Registrable Securities that the Company has
               been requested to Register for disposition as described in the
               request of such holders of Shares within ten (10) days or such
               longer period as shall be set forth in the notice, after the
               giving of the written notice by the Company; provided, however,
               that the Company shall not be obligated to effect any
               Registration except in accordance with the following provisions:

               (a)  The Company shall not be obligated to file and cause to
                    become effective more than two (2) registration statements
                    in which Registrable Securities are Registered pursuant to
                    this Section 2.3.

               (b)  Any offering of Registrable Securities in accordance with a
                    Registration pursuant to this Section 2.3 shall be an
                    underwritten offering through one or more underwriters
                    acceptable to the holders of Registrable Securities
                    requesting such Registration and the Company. The
                    underwriter or managing underwriter of such Registration
                    shall be authorized to determine the maximum amount of
                    Registrable Securities which in the judgment of such
                    underwriter may be sold at or about the then current market
                    value of the Common Stock of the Company and such
                    underwriter shall be empowered to reduce the number of
                    Registrable Securities which may be sold pursuant to such
                    Registration if in its judgment such reduction is necessary
                    in order not to materially and adversely affect the then
                    prevailing market price of the Common Stock. Any such
                    reduction shall be applied pro rata to those holders of

                                      -3-
<PAGE>
 
                    Registrable Securities requesting such Registration.

               (c)  In the event that the managing underwriter determines that
                    under then prevailing market conditions more shares of
                    Common Stock may be sold pursuant to such Registration than
                    the number of Registrable Securities requested to be
                    included therein, the Company may include in each such
                    Registration requested pursuant to this Section 2.3 any
                    authorized but unissued shares of Common Stock (or
                    authorized treasury shares) for sale by the Company or any
                    issued and outstanding shares of Common Stock for sale by
                    others, provided, however, that, if the number of shares of
                    Common Stock so included pursuant to this clause (b) exceeds
                    the number of Registrable Securities requested by the
                    holders of Shares requesting such Registration, then such
                    Registration shall be deemed to be a Registration in
                    accordance with and pursuant to Section 2.4; and provided
                    further, however, that the inclusion of such previously
                    authorized but unissued shares of Common Stock by others in
                    such Registration shall not prevent the holders of Shares
                    requesting such Registration from registering the entire
                    number of Registrable Securities requested by them.

               (d)  The Company shall not be required to file a registration
                    statement pursuant to this Section 2: (i) within six (6)
                    months after any other registration by the Company (other
                    than under "Excluded Forms," as defined in Section 2.4(a)
                    below) or (ii) for six (6) months after the request for
                    registration under this Section 2.3 if the Company is then
                    engaged in negotiations regarding a material transaction
                    which has not otherwise been publicly disclosed, or such
                    shorter period ending on the date, whichever first occurs,
                    that such transaction is publicly disclosed, abandoned or
                    consummated.

               (e)  The registration rights granted pursuant to this section
                    shall have no force or effect until the earlier of the
                    Company has completed a public offering under the Securities
                    Act or otherwise become obligated to file periodic or other
                    reports pursuant to Section 13 of the 1934 Act."

          2.4  Piggyback Registration
               ----------------------

               (a)  Each time that the Company proposes to Register a public
                    offering solely of its Common Stock (not including an
                    offering of Common stock issuable upon conversion or
                    exercise of other securities), other than pursuant to a
                    Registration Statement on Form S-4 or Form S-8 or similar or
                    successor forms (collectively, "Excluded Forms"), the
                    Company shall promptly give written notice of such proposed
                    Registration to all holders of Shares, which shall offer
                    such holders the right to request inclusion of any
                    Registrable Securities in the proposed Registration.

               (b)  Each holder of Shares shall have ten (10) days or such
                    longer period as shall be set forth in the notice from the
                    receipt of such notice to deliver to 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)  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 2.4(b)
                    may specify that the Registrable Securities 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
                    2.4(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.

               (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 other issued and outstanding shares of
                    Common Stock proposed to be included therein by holders
                    other than the holders of Registrable Securities (such other
                    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, then the number of such shares to be
                    included in such underwritten public offering shall be
                    reduced, and shares shall be excluded from such underwritten
                    public offering in a number deemed necessary by such
                    managing underwriter, first by excluding shares held by the
                    directors, officers, employees and 

                                      -5-
<PAGE>
 
                    founders of the Company, 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 such holder
                    proposed to include.

               (f)  All Shares that are not included in the underwritten public
                    offering shall be withheld from the market by the holders
                    thereof for a period, not to exceed 6 months following a
                    public offering, that the managing underwriter reasonably
                    determines as necessary in order to effect the underwritten
                    public offering.  The holders of such Shares shall execute
                    such documentation as the managing underwriter reasonably
                    requests to evidence this lock-up.

          2.5  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 and
                    use its best efforts to cause such Registration Statement to
                    become and remain effective in accordance with Section
                    2.5(b) hereof, 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 nine
                    months and to comply with the provisions of the Securities
                    Act with respect to the sale or other disposition of all
                    Registrable Securities covered by such registration
                    statement;

               (c)  furnish to each Selling Shareholder such number of copies of
                    any summary prospectus or other prospectus, including a
                    preliminary prospectus, in conformity with the requirements
                    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;

               (d)  use its best efforts to register or qualify the Registrable
                    Securities covered by such registration statement under the
                    securities or blue sky laws of such jurisdictions as each
                    Selling Shareholder shall reasonably request and do any and
                    all other acts or things which 

                                      -6-
<PAGE>
 
                    may be 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 submit to liability for state or local taxes
                    where it is not 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
                    2.4(b) hereof, notify each Selling Shareholder of the
                    happening of any event as a result of which the prospectus
                    included in such Registration, 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 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.

          2.5  Expenses.  The Company shall pay all Registration Expenses
               --------                                                  
               incurred by the Company in complying with this Section 2;
               provided, however, that all underwriting discounts and selling
               commissions applicable to the Registrable Securities covered by
               registrations effected pursuant to section 2.3 hereof shall be
               borne by the seller or sellers thereof, in proportion to the
               number of Registrable Securities sold by such seller or sellers.

                    shall indemnify each Selling Shareholder, each of its
                    officers, directors and constituent partners, and each
                    person controlling such Selling Shareholder, and each
                    underwriter thereof, if any, and each of its officers,
                    directors, constituent partners, and each person who
                    controls such underwriter, 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
                    such underwriter, each of their officers, directors and
                    constituent partners and each person who controls any such
                    Selling Shareholder or underwriter, for any legal and any
                    other expenses as reasonably 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, however, 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 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.

                    ----------------------------------

                    directors and officers, each underwriter, if any, of the
                    Company's Registrable Securities covered by a Registration

                    directors and constituent partners and each 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 inactions required of
                    such Selling Shareholder in connection with the Registration
                    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 legal
                    and any other expenses reasonably incurred in connection
                    with investigating or defending any such claim, loss,
                    damage, liability or action; such indemnification and
                    reimbursement shall be to the extent, but only to the
                    extent, that such untrue statement (or alleged untrue
                    statement) or omission (or alleged omission) is made in such
                    Registration Statement or prospectus in reliance upon and in
                    conformity with written information furnished to the Company
                    by such Selling Shareholder and stated to be specifically
                    for use in connection with the offering of Registrable
                    Securities.

             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
                    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 

                                      -9-
<PAGE>
 
                    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
                    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 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 legal or
                    other fees or expenses reasonably incurred by such party in
                    connection with investigating or defending any action, suit,
                    proceeding or claim.

3.        Covenants of the Company.
          ------------------------ 

          The Company agrees to:

          (a)  Notify the holders of Registrable Securities included in a
               Registration Statement of the issuance by the Commission of any
               stop order suspending the effectiveness of such Registration
               Statement or the initiation of any proceedings for that purpose.
               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,
               after it has become obligated to file periodic or other reports
               pursuant to Section 13 of the 1934 Act agrees to:

               (i)   make and keep public information 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 and Exchange Act of 1934
                     (the "1934 Act"); and

               (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 that it has complied
                     with the reporting requirements of Rule 144 (at any time
                     after 90 days after the effective date of the first
                     registration statement filed by the Company), the
                     Securities Act and the 1934 Act (at any time after it has
                     become subject to such reporting requirements), (b) a copy
                     of 

                                      -11-
<PAGE>
 
                     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 the 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.

4.        Miscellaneous.
          ------------- 

          (a)  Notices required or permitted to be given hereunder shall be in
               writing and shall be deemed to be sufficiently given when
               personally delivered or sent by registered mail, return receipt

               party furnishes by notice given in accordance with this Section
               4(a);

          (b)  Failure of any party to exercise any right or remedy under this
               Agreement or otherwise, or delay by a party in exercising such
               right or remedy, will not operate as a waiver thereof.  No waiver
               will be effective unless and until it is in writing and signed by
               the party giving the waiver;

          (c)  This Agreement shall be enforced, governed and construed in all
               respects in accordance with the laws of the State of Connecticut,
               as such laws are applied by Connecticut courts to agreements
               entered into and to be performed in Connecticut by and between

               this Agreement is invalid or unenforceable under any applicable
               statute or rule of law, then such provision shall be deemed
               inoperative to the extent that it may conflict therewith and
               shall be deemed modified to conform with such statute or rule of
               law.  Any provision hereof which may prove invalid or
               unenforceable under any law shall not affect the validity or

This Registration Rights Agreement (this "Agreement") is made this 11th day of
October, 1996, by ACCENT COLOR SCIENCES, INC., a Connecticut corporation (the
"Company") for the benefit of each Purchaser (individually a "Purchaser" and

(the "Purchase Agreement") with the Company of even date herewith.

BACKGROUND
- ----------

Pursuant to the Note Purchase Agreement, the Company has offered for sale

               Register for disposition as described in the request of such

               not be obligated to effect any Registration except in accordance
               with the following provisions:

               (a)  The Company shall not be obligated to file and cause to
                    become effective more than one (1) registration statement in
                    which Registrable Securities are Registered pursuant to this

                    others, provided, however, that, if the number of shares of
                    Common Stock so included pursuant to this clause (b) exceeds
                    the number of Registrable Securities requested by the
                    holders of Shares requesting such Registration, then such
                    Registration shall be deemed to be a Registration in
                    accordance,with and pursuant to Section 2.3; and provided
                    further, however, that the inclusion of such previously
                    authorized but unissued shares of Common Stock by the
                    Company or issued and outstanding shares of Common Stock by
                    others in such Registration shall not prevent the holders of
                    Shares requesting such Registration from registering the
                    entire number of Registrable Securities requested by them.

               (c)  The Company shall not be required to file a registration
                    statement pursuant to this Section 2: (i) within twelve
                    months after October 11, 1996, (ii) within six (6) months
                    after any other registration by the Company (other than
                    under "Excluded Forms," as defined in Section 2.3 (a) below)
                    or (iii) for six (6) months after the request for
                    registration under this Section 2.2 if the Company is then
                    engaged in negotiations regarding a material transaction
                    which has not otherwise been publicly disclosed, or such
                    shorter period ending on the date,

<PAGE>
 
                    whichever first occurs, that such transaction is publicly
                    disclosed, abandoned or consummated.

               (d)  The registration rights granted pursuant to this section
                    shall have no force or effect until the earlier of the
                    Company has completed its initial public offering (the
                    "IPO") under the Securities Act or otherwise become
                    obligated to file periodic or other reports pursuant to
                    Section 13 of the 1934 Act.

     2.3  Piggyback Registration
          ----------------------

               (a)  Each time that the Company proposes to Register a public
                    offering solely of its Common Stock, other than pursuant to
                    a Registration Statement on Form S-4 or Form S-8 or similar
                    or successor forms (collectively, "Excluded Forms"), the
                    Company shall promptly give written notice of such proposed
                    Registration to all holders of Shares, which shall offer
                    such holders the right to request inclusion of any
                    Registrable Securities in the proposed Registration,
                    provided that such right shall not be exercisable in
                    connection with the IPO, or prior to the earlier of (i)
                    October 11, 1997 or six (6) months following the IPO.

               (b)  Each holder of Shares shall have ten (10) days or such
                    longer period as shall be set forth in the notice from the
                    receipt of such notice to deliver to 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)  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)
                    may specify that the Registrable Securities 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.

               (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 other issued and 

                                      -4-
<PAGE>
 
                    outstanding shares of Common Stock proposed to be included
                    therein by holders other than the holders of Registrable
                    Securities (such other 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, then the
                    number of such shares to be included in such underwritten
                    public offering shall be reduced, and shares shall be
                    excluded from such underwritten public offering in a number
                    deemed necessary by such managing underwriter, first by
                    excluding shares held by the directors, officers, employees
                    and founders of the Company, 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 such holder
                    proposed to include.

               (f)  All Shares that are not included in the underwritten public
                    offering shall be withheld from the market by the holders
                    thereof for a period, not to exceed 6 months following a
                    public offering, that the managing underwriter reasonably
                    determines as necessary in order to effect the underwritten
                    public offering.  The holders of such Shares shall execute
                    such documentation as the managing underwriter reasonably
                    requests to evidence this lock-up.

     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 and
                    use its best efforts to cause such Registration Statement to
                    become and remain effective in accordance with Section
                    2.4(b) hereof, 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 nine
                    months and to comply with the provisions of the Securities
                    Act with respect to the sale or other disposition of all
                    Registrable Securities covered by such registration
                    statement;

               (c)  furnish to each Selling Shareholder such number of copies of
                    any summary prospectus or other prospectus, including a
                    preliminary prospectus, in conformity with the requirements
                    of the Securities Act, 

                                      -5-
<PAGE>
 
                    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;

               (d)  use its best efforts to register or qualify the Registrable
                    Securities covered by such registration statement under the
                    securities or blue sky laws of such jurisdictions as each
                    Selling Shareholder shall reasonably request and do any and
                    all other acts or things which may be 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 submit to liability for
                    state or local taxes where it is not 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
                    2.3(b) hereof, notify each Selling Shareholder of the
                    happening of any event as a result of which the prospectus
                    included in such Registration, 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

                    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

                 information furnished to the Company by such Selling

          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 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 

                                      -8-
<PAGE>
 
                    or circumstances, be liable for the reasonable 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 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 legal or
                    other fees or expenses reasonably incurred by such party in
                    connection with investigating or defending any action, suit,
                    proceeding or claim.

        3.   Covenants of the Company.

                  Registration Statement of the issuance by the Commission of
                  any stop order suspending the effectiveness of such
                  Registration Statement or the initiation of any proceedings
                  for that purpose. 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.

               that may at any time permit the Purchasers to sell securities of
               the Company to the public without registration, the Company,
               after it has become obligated to file periodic or other reports
               pursuant to Section 13 of the 1934 Act agrees to:

               (i)     make and keep public information available, as those

                       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 and Exchange Act of
                       1934 (the "1934 Act"); and

               (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 that it has
                       complied with the reporting requirements of Rule 144 (at
                       any time after 90 days after the effective date of the
                       first registration statement filed by the Company), the
                       Securities Act and the 1934 Act (at any time after it has
                       become subject to such reporting requirements), (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 the 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)  Failure of any party to exercise any right or remedy under this
               Agreement or otherwise, or delay by a party in exercising such
               right or remedy, will not operate as a waiver thereof.  No waiver
               will be effective unless and until it is in writing and signed by
               the party giving the waiver;

          (c)  This Agreement shall be enforced, governed and construed in all
