consent or approval has been obtained, and the Company will cooperate with
Purchaser in any lawful and economically feasible arrangement to provide that
Purchaser shall receive the interest of the Company in the benefits of the
Business Assets and the license described in Section 1.3(a)(ii) notwithstanding

                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company hereby represents and warrants to Purchaser, as of the
date hereof and as of the Closing Date, as follows:

          3.1  Existence; Good Standing; Corporate Authority.  Each of the
               ---------------------------------------------              
Company and O-Sub is (i) a corporation duly incorporated, validly existing and
                      -                                                       
in good standing under the laws of its jurisdiction of incorporation and (ii) is
                                                                          --    
duly licensed or qualified to do business as a foreign corporation and is in
good standing under the laws of any other state of the United States or any
other jurisdiction in which the character of the properties owned or leased by
it or in which the transaction of its business makes such licensure,
qualification or good standing necessary, except where the failure to be so in
good standing or to be so licensed or qualified, individually or in the
aggregate, would not have a material adverse effect on the business, operations,
results of operations, assets, financial condition or prospects of the Company
or O-Sub (a "Material Adverse Effect").  Each of the Company and O-Sub has the
             -----------------------                                          
requisite corporate power and authority to own, operate and lease its properties
and carry on its business (including, in the case of Purchaser, the Inkjet
Business) as now conducted.

          3.2  Authorization, Validity and Effect of Agreements.  The Company
               ------------------------------------------------              
has the requisite corporate power and authority to execute and deliver this
Agreement and to consummate the transactions contemplated hereby.  The execution
and delivery of this Agreement by the Company and the consummation by the
Company of the transactions contemplated hereby have been duly and validly
authorized by the Board of Directors, and no other corporate proceedings on the
part of the Company or its stockholders are necessary to authorize this
Agreement or to consummate the transactions contemplated hereby.  This Agreement
has been duly and validly executed and delivered by the Company, and (assuming
this Agreement constitutes a valid and binding obligation of Purchaser)
constitutes the valid and binding obligation of the Company, enforceable against
the Company in accordance with its terms.

          3.3  Compliance with Laws.  Except as set forth in Schedule 3.3,
               --------------------                                       
neither the Company nor O-Sub is in violation of any Laws of any Governmental
Entity applicable to the Company, O-Sub or any of their respective properties or
assets (including the Inkjet Business), except for violations which,
individually or in the aggregate, would not have a Material Adverse Effect.

                                       11
<PAGE>
 
          3.4  Capitalization, etc. The Company owns all of the O-Sub Shares,
               -------------------                                           
and each of the O-Sub Shares is duly authorized, validly issued, fully paid and
nonassessable and owned by the Company free and clear of all Encumbrances
(except for any Encumbrance pursuant to the Loan and Pledge Agreement).  There
are no other shares of capital stock of O-Sub, no securities of O-Sub
convertible or exchangeable for shares of capital stock or voting securities of
O-Sub, and no existing options, warrants, calls, subscriptions, convertible
securities, or other rights, agreements or commitments that obligate the Company
or O-Sub to issue, transfer or sell any shares of capital stock of, or equity
interests in, O-Sub.  There are no outstanding obligations of the Company or O-
Sub to repurchase, redeem or otherwise acquire any shares of capital stock of O-
Sub.

          3.5  Assets.  (a) The Company owns and has good title or has the right
               ------                                                           
to use all the Business Assets and Secondary Assets (except as may be disposed
of in the ordinary course of business after the date hereof and in accordance
with this Agreement), in each case free and clear of any and all Encumbrances.
The Business Assets and the Secondary Assets, taken as a whole, constitute all
the properties and assets used or held for use in connection with, necessary for
the conduct of or otherwise material to the Inkjet Business as reasonably
conducted and as conducted during the past twelve months (except inventory sold,
cash disposed of, accounts receivable collected, prepaid expenses realized,
contracts fully performed, and properties or assets replaced by equivalent or
superior properties or assets, in each case in the ordinary course of business).
There are no assets or properties used in the operation of the Inkjet Business
and owned by any Person other than the Company that will not as of the Closing
Date be leased or licensed to Purchaser under valid, current leases or license
arrangements.  The Business Assets and Secondary Assets are in all material
respects adequate for the purposes for which such assets are currently used or
are held for use, and are in reasonably good repair and operating condition
(subject to normal wear and tear) and, to the knowledge of the Company, there
are no facts or conditions affecting such assets that could, individually or in
the aggregate, interfere in any material respect with the use, occupancy or
operation thereof as currently used, occupied or operated, or their adequacy for
such use.

          (b) Neither the purchase and sale of the Business Assets and the
licenses contemplated hereby upon the exercise of the Inkjet Option, nor the
purchase and sale of the O-Sub Shares upon the exercise of the Subsidiary Stock
Option would constitute the sale of "substantially all" of the Company's
properties and assets pursuant to Section 271 of the DGCL, and such Section 271
shall not be applicable to any of the transactions contemplated by this
Agreement.  Neither the Inkjet Business nor O-Sub represents more than 45% of
(i) the book value of the Company's assets, (ii) the Company's revenues, or
(iii) the Company's profit, in each case on a consolidated basis.

                                       12

          3.6  No Violation.  Except as set forth in Schedule 3.6, neither the
               ------------                                                   
execution and delivery by the Company of this Agreement nor the consummation by
the Company of the transactions contemplated hereby will:  (i) violate, conflict
                                                            -                   
with or result in a breach of any provisions of the Certificate of Incorporation
or Bylaws (or comparable constituent documents) of the Company or O-Sub; (ii)
                                                                          --

default (or an event which, with notice or lapse of time or both, would
constitute a default) under, result in the termination or in a right of
termination of, accelerate the performance required by or benefit obtainable
under, result in the triggering of any payment or other obligations pursuant to,
result in the creation of any Encumbrance upon any of the Inkjet Business, the
O-Sub Shares or the O-Sub business (other than any Encumbrance created
hereunder) under, or result in there being declared void, voidable, subject to
withdrawal, or without further binding effect, any of the terms, conditions or
provisions of any note, bond, mortgage, indenture, deed of trust or any license,
franchise, permit, lease, contract, plan, agreement or other instrument,
commitment or obligation to which the Company or O-Sub is a party, by which the
Company or O-Sub or any of their respective properties is bound, or under which
the Company or any of its subsidiaries or any of their respective properties is
entitled to a benefit, except for any of the foregoing matters which
individually or in the aggregate would not have a Material Adverse Effect or
prevent or materially delay the consummation of the transactions contemplated
hereby.

          3.7  Merger Agreement.  Each of the representations and warranties
               ----------------                                             
made by the Company in the Merger Agreement (including the relevant exceptions
set forth in the Disclosure Letter) are true and correct to the extent they

delivery of this Agreement and the consummation by Purchaser and Merger Sub of
the transactions contemplated hereby and thereby have been duly and validly
authorized by the Board of Directors of Purchaser and no other corporate

Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction.  If any provision of
this Agreement is unenforceable, the provision shall be interpreted to apply to

(collectively, the "Company Indemnities") from and against any and all Losses
                    -------------------
resulting from or arising out of:

          (i)    any inaccuracy in any representation or warranty made by 
     Purchaser herein;

          (ii)   any failure of Purchaser to perform any covenant or agreement
     hereunder or fulfill any other obligation in respect hereof; and

          (iii)  if the Inkjet Option is exercised and consummated at the

indemnification obligations with respect to any claim for indemnification
pursuant to clauses (i) and (ii) of the first sentence of this Section 5.12(b)
shall not exceed $5,000,000.

          (c) Indemnification Procedures.  In the case of any claim asserted by
              --------------------------                                       
a third party against a party entitled to indemnification under this Agreement
(the "Indemnified Party"), notice shall be given by the Indemnified Party to the
      -----------------                                                         
party required to provide indemnification (the "Indemnifying Party") promptly
                                                ------------------           
after such Indemnified 

                                       18

Party has actual knowledge of any claim as to which indemnity may be sought, and
the Indemnified Party shall permit the Indemnifying Party (at the expense of
such Indemnifying Party) to assume the defense of any claim or any litigation
resulting therefrom, provided that (i) the counsel for the Indemnifying Party
                                    -
who shall conduct the defense of such claim or litigation shall be reasonably
satisfactory to the Indemnified Party, (ii) the Indemnified Party may
                                        --
participate in such defense at such Indemnified Party's expense, and (iii) the
                                                                      ---
omission by any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its indemnification obligation under this
Agreement. Except with the prior written consent of the Indemnified Party, no
Indemnifying Party, in the defense of any such claim or litigation, shall
consent to entry of any judgment or order, interim or otherwise, or enter into
any settlement with respect to such claim or litigation. In the event that the
Indemnified Party shall in good faith determine that the conduct of the defense
of any claim subject to indemnification hereunder or any proposed settlement of
any such claim by the Indemnifying Party might be expected to affect adversely
the ability of Purchaser to conduct its business, or that the Indemnified Party
may have available to it one or more defenses or counterclaims that are
inconsistent with one or more of those that may be available to the Indemnifying
Party in respect of such claim or any litigation relating thereto, the
Indemnified Party shall have the right at all times to take over and assume
control over the defense, settlement, negotiations or litigation relating to any
such claim at the sole cost of the Indemnifying Party, provided that if the
Indemnified Party does so take over and assume control, the Indemnified Party
shall not settle such claim or litigation without the written consent of the
Indemnifying Party, such consent not to be unreasonably withheld. In the event
that the Indemnifying Party does not accept the defense of any matter as above
provided, the Indemnified Party shall have the full right to defend against any
such claim or demand and shall be entitled to settle or agree to pay in full
such claim or demand. In any event, the Indemnifying Party and the Indemnified
Party shall cooperate in the defense of any claim or litigation subject to this
Section 5.12 and the records of each shall be available to the other with
respect to such defense.

hereof each signed by less than all, but together signed by all, of the parties
hereto.
