-----------------------------------------------------------------
expect the full scale research and development program for the Initial Jericho

                                       7

<PAGE>

Product to take three (3) years, with the commercial sale of such Initial
Jericho Product expected to commence in the first calendar quarter of 2004. HP's
funding of Indigo Jericho R&D for the Initial Jericho Product shall be as
follows:

     5.4.1 Payment of $5m no later than January 1, 200l.
     -----

     5.4.2 Payment of $3.75m no later than January 1, 2002.
     -----

     5.4.3 Payment of $3.75m no later than 10 days after the go/no go
     -----
     checkpoint of June 30, 2002 (provided HP elects to "go" at that
     checkpoint).

     5.4.4 Payment of $12.5m no later than January 1, 2003 (provided HP elects
     -----
     to "go" at the June 30, 2002 checkpoint).

5.5  Indigo Funding of Indigo Jericho R&D for Initial Jericho Product.
---------------------------------------------------------------------
Indigo shall match, dollar-for-dollar, the aforesaid HP funding of Indigo
Jericho R&D.


5.6  Go/No Go Checkpoints. Notwithstanding the foregoing payment schedule,
-------------------------
there shall be go/no go checkpoints on June 30, 2002 and on September 30, 2003,
at which checkpoints HP may in its absolute discretion decide to terminate the
Agreement. If HP so terminates on June 30, 2002, it shall have no obligation to
make any further payments beyond that date, except for fair "exit charges"
payable to Indigo. If HP so terminates on September 30, 2003, it shall incur no
additional exit charges. In such event, all Indigo exit expenses shall be
deemed to have been covered by HP's prior payment of $12.5m for Indigo Jericho
R&D during calendar year 2003.

5.7  Personnel. Throughout the term of the Indigo research and development
--------------
effort, an estimate of 10 technical experts employed by HP shall, at HP's
expense, be stationed on a full-time basis at Indigo's premises in Israel (the
"Relocated Personnel"). The Relocated Personnel shall have experience in fields
to be determined by mutual agreement of the Parties, it being anticipated that
such fields will likely range from color science and imaging to project
management, testing and value engineering. The Relocated Personnel shall comply
with all relevant Indigo policies regarding safety, security and other work
practices.

5.8  Funding for New Jericho Product Development and Further Jericho Product
----------------------------------------------------------------------------
R&D. The Parties shall fbnd all new Jericho Products and all further Jericho
---
Product R&D which the Parties undertake pursuant to section 3.2. It is the
intention of the Parties that such funding be allocated between the Parties in
the same ratio as in the Initial Jericho Product research and development
period, with HP funding HP Jericho R&D, as well as one-half of the Indigo
Jericho R&D, payable annually in advance and otherwise as set forth below in
this section 5.8. From the time the

                                       8

<PAGE>

original $50 million R&D funding for the Initial Jericho Product is spent. The
Parties will agree an annual Indigo Jericho R&D budget to be at least 2 x 5% of
Indigo's total revenue from HP and all other Indigo revenue from Jericho Product
sales during the prior calendar year. To the extent that 5% of Indigo's
aforesaid prior year's revenue is inadequate to cover 50% of the jointly-agreed
Indigo Jericho R&D budget, HP will fund not only its 50% share of said R&D
budget but will also fund 100% of the shortfall, with the amount of such
shortfall to be credited against HP's R&D commitment in future years.

6.   Manufacturing

6.1  Commencement of Jericho Product Manufacturing. Once the Parties agree that
--------------------------------------------------
a prototype meets the relevant product specifications, commercial manufacturing
of the relevant Jericho Product shall commence. If the Parties are unable to
agree as aforesaid, HP's view shall prevail.

6.2  Ink Manufacturing. All ink manufacturing for the Jericho Product shall be
---------------------
done by Indigo and the first ink manufacturing plant for the Jericho Product
shall be established in Israel. Subsequent ink plants will be built in other
geographical locations if necessary.

6.3  Long-Term Manufacturing of Other Consumables. If, at any time, in either
------------------------------------------------
Party's reasonable opinion, it becomes necessary to manufacture Consumables
(other than ink) for Jericho Products in any locations other than Israel, the
Parties shall, in consultation with one another, have the right to specify the
new locations where such Consumables should be manufactured, and the
manufacturer thereof. In making their determination, the Parties will give
particular consideration to the value and secrecy of the Indigo know-how
utilized in manufacturing the said Consumables with a view to maximizing the
protection of Indigo's Intellectual Property.

6.4  Long-Term Manufacturing Strategy. The Parties shall regularly review,
------------------------------------
restructure, and/or relocate manufacturing of Jericho Products (other than ink)
as reasonably necessary to give effect to HP's strong preference for the
manufacture of Jericho Products by global third party contract manufacturers,
focused on pursuing low manufacturing cost, high quality, access to tax havens,
operational hedging, and low supply chain cost with the strategy to cover all
manufacturing capacity investments necessary to create a manufacturable product
(tooling, production prototypes, etc.) in the per unit product cost of goods
sold, leveraging from the existing infrastructure of the third party.

6.5  Minimization of Manufacturing Costs. If, at any time, HP is able to,
----------------------------------------
reasonably evidence that, either by itself or using third parties, it can
manufacture any or all components of the Jericho Products (other than ink)
significantly more cost

                                       9

<PAGE>

effectively than may then be manufactured by Indigo (or the then current
manufacturer), HP shall, in consultation with Indigo. have the right. over a
reasonable period, to transfer such manufacturing to itself or such third party,
as the case may be. In making a decision to transfer manufacturing, HP must make
provision for recovery over a reasonable period of reasonable sunk costs
invested by Indigo in the manufacturing process as part of the proposal to
transfer manufacturing.

6.6  Funding of Manufacturing Infrastructure. The Parties agree that the Party
--------------------------------------------
undertaking any component of manufacturing pursuant to this Agreement will be
responsible for the funding of the manufacturing plant and infrastructure needed
to carry out such manufacturing.

7.   Branding and Sales of Jericho Products

7.1  Branding. Each Party shall have the right to brand the Jericho Products
-------------
with its own brand, but without reference to the other Party unless the other
Party consents in writing.

7.2  Direct Sales. Each Party shall have the right to sell its own-branded
-----------------
Jericho Products for any application and in any geographical territory in the
world.

7.3  OEM Channel.

     7.3.1 Vertical Applications. Each Party shall have the right to OEM
     -----
     Jericho Products into Vertical Applications. When used in this section
     7.3.1, the term "Vertical Applications" shall mean applications outside
     of commercial printing, publishing, in-house/corporate printing and
     photofinishing.

     7.3.2 Non-Vertical Applications. Neither Party may OEM the Jericho
     -----
     Products into Non-Vertical Applications without the prior written
     consent of the other Party, such consent not to be unreasonably
     withheld. When used in this section 7.3, the term "Non-Vertical
     Applications" shall mean commercial printing, publishing,
     in-house/corporate printing and photofinishing.

of the BPM sharing formula for direct sales:

If HP were to sell to a customer, at a Selling Price of $100, HP-branded
consumables manufactured by INDIGO at a total PCOGS of $30, the BPM would be
$100 - $30 = $70.
HP would retain 70% of $70 = $49.
HP would pay INDIGO $51 (consisting of $30 in COGS plus Indigo's share of the
BPM, i.e., 30% of $70 = $21).

arose from unauthorized modification of such technical information; or (c) such
technical information was created solely as a result of the other Party's
specification.

     and the other Party (the "Terminating Party") terminates this Agreement
     based thereon:

                                       15

<PAGE>

     (a) the first mentioned Party ("Terminated Party") shall lose all
     Intellectual Property license rights granted to it by the Terminating Party
     under this Agreement pursuant to section 11 hereof, and


     (b) to the extent necessary for the Terminating Party to exercise its
     rights to make, use and sell Jericho Products under this Agreement, the
     Terminating Party shall be entitled to:

              (i) full immunity from suit (i.e., a non-assertion covenant,
              which is fully transferable to the Terminating Party's Affiliates
              as well as the Terminating Party's suppliers, vendors, and
              distributors of Jericho Products) for use of the Terminated
              Party's Background IP, Derivative IP and solely owned Foreground
              IP by the Terminating Party and its customers within the Jericho
              Field of Use;

              (ii) access to the Terminated Party's Jericho Know How;


     (c) if the Material Breach or Insolvency Event occurs after the first go/no
     go checkpoint, the Parties shall continue to pay each other the Jericho
     Product margin share set forth in section 10.

     (d) if the Material Breach is by Indigo, Indigo shall continue to supply
     Consumables to HP under the relevant margin sharing terms set forth in
     section 10.

12.4.2 Termination for Change of Control. If either Party terminates this
----------------------------------------
Agreement due to a Change of Control of the other Party pursuant to section
12.3.1 (iii) above, the Terminating Party shall have the right to revoke the
other Party's license to the Terminating Party's Background IP, Derivative IP
and solely owned Foreground IP granted pursuant to section 11 above.
Notwithstanding any such revocation, the Terminated Party shall have the right
to continue to use said IP in the manufacture and sale of Jericho Products being
manufactured at the date of such termination for a period of 12 months from the
date of the termination, provided that (a) the branding on all such Jericho
Products sold shall be the same as the branding used by the Terminated Party on
those Jericho Products before the termination; (b) the Terminated Party shall
not sell more of such Jericho Products during such 12 month period than 1.5
times the quantity sold during the 12 month period preceding the termination;
and (c) delivery of all such Jericho Products shall take place during the 15
month period following termination. For the sake of clarity, the rights to
Intellectual Property granted to said Terminating Party

                                       16

<PAGE>

     pursuant to section 11 shall be subject to the Terminating Party's
     continued payment to the other Party of the margin share set forth in
     section 10.

     ------------------------------------------------
     terminate the Agreement at:

     Indigo revenues pursuant to section 10; or

     (b) the second of the two go/no go checkpoints pursuant to section 12.3.l
     (iv) above, HP shall lose all Intellectual Property rights granted to it by
     Indigo under section 11 of this Agreement but (provided it has made all
     payments pursuant to section 5.4) shall not lose the rights to share in
     Indigo revenues pursuant to section 10.

     12.4.4 Termination at end of Term. Upon any expiry pursuant to section
     ---------------------------------
     12.2, all Intellectual Property license rights granted under section 11
     shall terminate. However, any Party shall have the right, by written notice
     to the other within 30 days of said expiry, to be granted, with respect to
     any Intellectual Property existing on said expiry date, an extension of
     such license rights for an additional period of up to 20 years, subject to
     the notifying Party's continued payment to the other Party of the Jericho
     Product margin share set forth in section 10.

     12.4.5 Each Party shall ensure that the provisions of this section 12
     ------
     are binding on its successors and permitted transferees and assigns.

12.5 Survival. Sections 10, 11, 12.4, 12.5, 13, 14, 15, 16, 17 and 18 shall

consumable that may compete with Jericho Products, so long as such products do
not employ the other Party's Intellectual Property, including, but not limited
to, Intellectual Property embodied in the Indigo Core Technology.

17.  General

17.1 Confidentiality.
--------------------

     17.1.1 Definition of Confidential Information. "Confidential Information"
     ---------------------------------------------
     means all information disclosed by a Party ("Disclosing Party") to the
     other Party ("Receiving Party") pursuant to, or in connection with, this
     Agreement, including any information disclosed in contemplation of this
     Agreement prior to the Effective Date, regardless of the form or manner of
     disclosure. "Confidential Information" shall not include information: (a)
     of which the Receiving Party was rightfully in possession prior to
     disclosure, as evidenced by appropriate documentation; (b) that was
     independently developed by employees or agents of the Receiving Party who
     have not received any Confidential Information provided by the Disclosing
     Party; (c) that the Receiving Party rightfully receives from a third party
     not owing a duty of confidentiality to the Disclosing Party; (d) that is or
     becomes publicly available without fault of the Receiving Party; (e) that
     is published incident to

                                       19

<PAGE>

patent application prosecution; or (f) that the Parties agree in writing will
not be treated as Confidential Information. Notwithstanding sub-section (e),
neither Party shall include Confidential Information of the other Party in any
patent application without the prior written consent of the other Party, such
consent not to be unreasonably withheld.

17.1.2 Identification as Confidential. Information of the Disclosing Party shall
-------------------------------------
be deemed Confidential Information if (i) disclosed in writing, the information
is marked by an appropriate legend, such as "HP Confidential" or "Indigo
Confidential," or (ii) disclosed orally or visually, the information is
designated (orally or in writing) contemporaneously or promptly thereafter, as
"HP Confidential" or "Indigo Confidential," or (iii) the disclosure in any form
(visually, orally, or in writing), by its very nature would reasonably be
understood to be confidential.

17.1.3 Confidentiality Obligations. The Receiving Party shall hold the
----------------------------------
Confidential Information of the Disclosing Party in confidence, using such
measures as the Receiving Party uses to protect the confidentiality of its own
confidential information of like importance, but in no event using less than
reasonable care. The Receiving Party shall not make any disclosure of such
Confidential Information other than to its employees and consultants on a
need-to-know basis. The Receiving Party shall inform each such employee and
consultant of the Receiving Party's confidentiality obligations under this
Agreement and will require each such person to sign an appropriate nondisclosure
agreement. The Receiving Party shall be liable for any breach of this section
17.1.3 by any of its employees or consultants acting within the scope of their
authority. The Receiving Party shall use the Disclosing Party's Confidential
Information solely to perform the activities contemplated by this Agreement and
for no other purpose. The Receiving Party shall return the Disclosing Party's
tangible Confidential Information to the Disclosing Party promptly upon the
Disclosing Party's request or termination of this Agreement, whichever occurs
first, unless the Receiving Party has a continuing right under this Agreement to
use such Confidential Information. Nothing herein shall prevent assignment of
the Parties' employees or consultants to other projects.

17.1.4 Exceptions. Notwithstanding anything to the contrary in section 17.1.3,
-----------------
disclosure of Confidential Information shall be permitted to the extent required
by order of a court or governmental authority, provided that the Disclosing
Party has been given timely notice of such requirement and that the Receiving
Party must cooperate with the Disclosing Party to limit the scope and effect of
such order.

                                       20

<PAGE>

     17.1.5 Residual Information. Access to Confidential Information hereunder
     ---------------------------
     shall not preclude an individual who has seen or been exposed to such
     Confidential Information for the purposes of this Agreement from working on
     future projects for the Receiving Party which are not prohibited hereunder
     and which relate to similar subject matters, provided that such individual
     does not make reference to any document or other tangible media containing
     the Confidential Information. Furthermore, nothing contained herein shall
     be construed as imposing any restriction on the Receiving Party's
     disclosure or use of any general learning, skills, or know-how developed by
     the Receiving Party's personnel under this Agreement, if such disclosure
     and use would be regarded by a person of ordinary skill in the relevant
     area as not constituting a disclosure or use of the Confidential
     Information.

     17.1.6 Injunctive Relief. Each Party acknowledges and agrees that the other
     ------------------------
     Party would suffer irreparable harm for which monetary damages would be an
     inadequate remedy if there were a breach of obligations under this section
     17.1. Each Party further acknowledges and agrees that equitable relief,
     including injunctive relief, would be appropriate to protect the other
     Party's rights and interests if such a breach were to arise, were
     threatened, or were asserted.

17.2 Publicity. So long as this Agreement is in effect, no Party or any of its
--------------
Affiliates shall issue or cause the publication of any press release or other
announcement with respect to the terms or implementation of this Agreement
without the prior consultation and approval of the other Party, except as my be
required by law; provided that such approval shall not be unreasonably withheld.
Any such publicity made in accordance with the terms of a joint communications
program shall not require approval under this section 17.2.

17.3 Assignment. Neither Party may assign any of its rights and/or obligations
---------------
hereunder (except to an Affiliate), whether by operation of law or otherwise,
without the prior written consent of the other Party, which consent shall not be
unreasonably withheld. Any assignment made in contravention of this section 17.3
shall be void. This Agreement shall inure to the benefit of and be binding upon
the Parties and their respective administrators, permitted successors and
permitted assigns.

17.4 Notices. Any notice, request, consent, approval, or communication
------------
(collectively a "Notice") under this Agreement shall be effective only if it is
in writing and (i) personally delivered, (ii) sent by certified or registered
mail, return receipt requested, postage prepaid (iii) sent by a nationally
recognized overnight delivery service, with delivery confirmed, or (iv) sent by
facsimile, with receipt confirmed, addressed as follows:

17.5 Amendments. The terms and provisions of this Agreement may not be modified
---------------
or amended without the written consent of each Party.

17.6 Severability. Every provision of this Agreement is intended to be
-----------------
severable. If any term or provision hereof is held by a court of competent
jurisdiction or regulatory authority to be illegal or invalid for any reason
whatsoever, the Parties agree to negotiate in good faith a next best alternative
term or provision, as the case may be, that retains the parties' original intent
to the greatest extent possible. If the Parties are unable to negotiate such
term or provision, the original term or provision shall be enforced to the
maximum extent permitted by law, and, in any event, such illegality or
invalidity shall not affect the validity of the remainder of the Agreement, or
the validity of such term or provision in other jurisdictions.

17.7 Non-Waiver. No provision of this Agreement shall be deemed to have been

waived except if the giving of such waiver is contained in a written Notice

favor the waiver was given.

construed to make the Parties partners or joint venturers with each other.

17.9 Third-Party Beneficiaries. This Agreement is intended to benefit the

shall not confer upon any other Person any rights or remedies.

 -----------------------------------------------------------
 this Agreement, it is contemplated that the OEM Agreement and the Stock
 Purchase Agreement (collectively "Related Agreements") shall be executed. This
 Agreement, together with the Related Agreements, constitutes the entire
 agreement between the Parties with respect to the subject matter hereof, and
 supersedes all prior drafts of the Agreement and all other agreements between

 not limited to the Strategic Affiliation Agreement referred to in the recitals
 and all Confidentiality Agreements between the Parties prior to the Effective
 Date.

 17.11 Construction. As used in this Agreement, all terms used in the singular

 require. The words "hereof," "herein," and "hereunder" refer to this Agreement

 be amended or supplemented, and not to any subdivision in this Agreement. When

 required under this Agreement, such Party may grant or withhold its approval or
 consent in its discretion. References to "section" or "Exhibit" shall be to the

------

       18.4.5.l In the case where the Parties are unable to resolve a Dispute
       involving or relating to an interpretation of the statement of work
       through non-binding mediation in accordance with section 18.4.4, the
       Parties agree to submit the Dispute immediately for binding
       arbitration by notice of written demand for arbitration to the other
       Party, with a copy to the American Arbitration Association ("AAA") in
       New York. The arbitration shall be administered by the AAA in New York
       in accordance with the Federal Arbitration Act, 9 U.S.C. (1995)
       ("FAA") and pursuant to the AAA's rules for commercial arbitration,
       provided that such rules do not conflict with the FAA or the expressed
       intentions of the Parties in this Agreement. In the case of any such
       conflict, the FAA and/or the expressed intentions of the Parties shall
       prevail over the AAA's rules.

       18.4.5.2 There shall be three arbitrators. Each Party shall select an
       arbitrator, and the third arbitrator shall be selected by the AAA. Such
       third arbitrator shall be an attorney with expertise in commercial law,
       and he or she shall serve as chairperson of the arbitral panel. Each of
       the arbitrators selected by the Parties shall be knowledgeable with

     18.4.5.4 The Parties shall be responsible for their own costs of
     arbitration, including the fees of the arbitrators, regardless of the
     outcome of the arbitration.

     18.4.5.5 The Parties agree that, in order to minimize expense and time
     delays, discovery for the arbitration shall be kept to a minimum, with the
     arbitrators determining the extent thereof.

     18.4.5.6 The arbitrators shall issue a statement as to their decision, but
     shall not issue any written opinion in connection with any Dispute.

     18.4.5.7 The power and authority of the arbitrators to award relief in
     connection with any Dispute shall be restricted by the terms of section
     15.1 of this Agreement. The Parties expressly agree to the enforceability
     of such restrictions, whether or not recognized by the law of the State of
     New York or the FAA. In no circumstances shall the arbitrators have the
     power or authority to award equitable, provisional or injunctive relief and
     the parties expressly agree that it shall be an abuse of the arbitrators'
     discretion to award such relief.
