                                     AGREEMENT

       NOW, THEREFORE, in consideration of the mutual promises and covenants
set forth herein, and other good and valuable consideration the sufficiency
of which is hereby acknowledged, the parties hereby agree as follows:

        1.    COMPOSITION of the Board. Each of the Holland Investors and the
Shareholders shall at all times exercise all rights they may have as holders
of Stock to appoint, to vote for, and to otherwise act in favor of
designating as members of the Board of Directors of the Company (the
"Board"): (i) one representative nominated by Challenge, only so long as
Challenge holds at least 25% of the shares

                                      -1-

it received as a result of the merger of Nogatech, Inc. a California
corporation with and into the Corporation, which merger was effectuated on
December 28, 1999 (ii) two representatives nominated by the Holland
Investors, one of whom shall be nominated by Holland Venture, only as long as
the Holland Investors collectively hold at least 10% of the Company's issued
and outstanding share capital, or (iii) one representative nominated by the
Holland Investors, only as long as the Holland Investors collectively hold at
least 5% of the Company's issued and outstanding share capital, in which case
the Holland Investors' representative shall be nominated by Holland Ventures.
Notwithstanding any provision of the Company's Certificate of Incorporation
as may be in effect, each of the Holland Investors and the Shareholders agree
that in any vote or any election for members of the Board, they each shall
take all such actions as are necessary in favor of the individuals designated
by the Purchasers to ensure the appointment of such individuals to serve as
members of the Board.  Nothing herein shall derogate form Sections 141 (k) of
the Delaware General Corporation Law.

       2.     PARTICIPATION ("TAG-ALONG") RIGHTS.

              a.     Subject to Section 2.b below, in the event that Nathan
Hod and/or Arie Heiman, jointly or severally (the "Selling Shareholder"),
initiates or otherwise receives a bona-fide offer from a third party (a
"Proposed Purchaser") to purchase all or any portion of the Stock owned by
the Selling Shareholder (a "Proposed Transfer"), then each Holland Investor
and the Purchaser, severally, shall have the right (the "Participation
Right") to require the Proposed Purchaser to purchase from such each of them
under the same terms and conditions as the Proposed Transfer, up to the
number of shares of Stock owned by each Holland Investor and the Purchaser
multiplied by the ratio between the number of shares of Stock which the
Selling Shareholder is offering to sell and the total number of shares of
Stock held by the Selling Shareholder prior to the sale.

              If the Proposed Transfer shall relate to the sale by the
Selling Shareholder of an aggregate of more than 50% of their shares of Stock
in the Company, then each Holland Investor and the Purchaser shall have the
right to require the Proposed Purchaser to purchase from such Holland
Investor and the Purchaser all of the shares of Stock owned by it.

              A notification regarding the Proposed Transfer shall be
forwarded to each Holland Investor and the Purchaser by the Selling
Shareholder in writing, 30 days prior to the consummation of the proposed
transaction.

              If the Proposed Purchaser refuses to complete a transaction
with any Holland Investor or the Purchaser as described in this Section 2.a.
and the Selling Shareholder completes the Proposed Transfer in derogation of
this Section 2, then the Selling Shareholder shall be obligated to purchase
from such Holland Investor and the Purchaser the same number of shares which
such Holland Investor and the Purchaser would otherwise have been permitted
to sell under this Section and under the same terms and conditions to the
Proposed Purchaser.

              b.     Notwithstanding anything to the contrary contained
herein, no Participation Right shall arise in the event of:

                     i.    a Proposed Transfer by Arie Heiman at any time to
a

                                      -2-
<PAGE>

family member; or

                     ii.   a Proposed Transfer by Nathan Hod (a) at any time
to a family member, (b) at any time after termination without cause of his
position as director of the Company, and/or (c) at any time after he is
unable to fulfill the duties of director of the Company by reason of death,
disability, illness, incapacitation, or otherwise.

       3.     TERMINATION.  The foregoing provisions of Section 2 shall
terminate upon the earlier of: (i) the closing of an IPO yielding ten million
US dollars ($10,000,000) to the Company; or (ii) the consummation of a merger
or sale of the Company in which the Company is not the consolidated or
surviving company and the controlling shareholders (or their affiliates) of
the Company are not the controlling shareholders of the surviving company.
Notwithstanding the foregoing, the provisions of Section 2 shall terminate as
to any Investor on the date that such Investor holds less than twenty five
percent (25%) of his/its shares acquired pursuant to his/its respective Stock
Purchase Agreement.

       4.     MISCELLANEOUS

              a.   FURTHER ASSURANCES.  Each of the parties hereto shall
perform such further acts and execute such further documents as may
reasonably be necessary to carry out and give full effect to the provisions
of this Agreement and the intentions of the parties as reflected thereby.

              b.   SEVERABILITY.  If any provision of this Agreement is held
by a court of competent jurisdiction to be unenforceable under applicable
law, then such provision shall be excluded from this Agreement and the
remainder of this Agreement shall be interpreted as if such provision were so
excluded and shall be enforceable in accordance with its terms; provided,
however, that in such event this Agreement shall be interpreted so as to give
effect, to the greatest extent consistent with and permitted by applicable
law, to the meaning and intention of the excluded provision as determined by
such court of competent jurisdiction.

              c.   SUCCESSORS AND ASSIGNS.  Except as otherwise expressly
provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors and administrators of
the parties hereto.

              d.    ENTIRE AGREEMENT. This Agreement and the exhibits attached
hereto and the other documents delivered pursuant hereto constitute the full
and entire understanding and agreement between and among the parties with
regard to the subjects hereof and thereof, and supersede all prior agreements
and understandings between and among the parties with regard to the subjects
hereof and thereof, including, without limitation, the Term Sheet dated April
