                    AMENDED AND RESTATED
                   STOCKHOLDERS' AGREEMENT


     THIS AMENDED AND RESTATED STOCKHOLDERS' AGREEMENT (this
"AGREEMENT") is madeasof this 6th day of July, 1997, by and among
SOUNDVIEW TECHNOLOGIES INCORPORATED, a Delaware corporation (the
"COMPANY"), H. Lee Browne ("BROWNE"), a natural person, David H.
Schmidt ("SCHMIDT"), a natural person, and ACACIA RESEARCH
CORPORATION, a California corporation ("ACACIA").


                        BACKGROUND


          The Company was formed in March 1996 for the purpose,
among other things, of owning, developing and exploiting United
States patent number 4,554,584 and all related technology (the
"PATENT").

          The Company was initially capitalized by issuing
7,500,000 shares of Common Stock, par value $0.001 per share (the
"COMMON STOCK"), in 1996 and the parties hereto entered into a
Stockholders' Agreement relating to election of directors and
various other matters.  As of the date hereof, Acacia is
purchasing shares from Browne and Schmidt and consequently Acacia
owns approximately 51% of the total number of issued and
outstanding shares of Common Stock on a fully diluted basis, and
Browne and Schmidt each own approximately 9.5% of the total
number of issued and outstanding shares of Common Stock on a
fully diluted basis.  Carl M. Elam and Dale A. Leavy (the
"INVENTORS") each owns 525,000 shares of Common Stock
representing in the aggregate 14% of the total number of issued
and outstanding shares of Common Stock on a fully diluted basis. 
The remaining shares are owned by other investors.

          The Company, Acacia, Browne and Schmidt desire to enter
into this Agreement to set forth certain rights and obligations
in respect of the Common Stock and the Company.

     In consideration of the foregoing and the agreements set
forth below, the parties agree with each other, as follows:

          BOARD OF DIRECTORS.

          1.1  DESIGNATED BOARD.  As of the date hereof, the only
members of the Board of Directors are H. Lee Browne, David H.
Schmidt, Paul R. Ryan and CarlM. Elam.  Acacia, Browne and
Schmidt desire to expand the size of the Board to five (5)
directors and will take all necessary action to adjust the size
of the Board.  At each meeting of the stockholders for the
election of directors or any solicitation of written consents for
such purpose or in filling any vacancies on the Board, Acacia,
Browne and Schmidt shall vote all shares of the Company's Common
Stock and any other shares of equity securities of the Company
now owned or hereafter acquired or controlled by them
(collectively, the "STOCK"), and otherwise use their best efforts
as stockholders and directors of the Company, to elect the
Designated Board (as defined below) which shall constitute the
entire Board of Directors.  The "DESIGNATED BOARD" shall consist
of (i) three members designated by Acacia, (ii) one member
designated by Browne and (iii) one member designated by Schmidt;
provided, however, that in the event that (and for so long as)
Acacia holds less than 50% of the Common Stock as a result of
events arising out of Acacia's failure to timely pay principal of
and interest on two Notes, each dated the date hereof, each made
by Acacia in the principal amount of $450,000, one in favor of
Browne and the other in favor of Schmidt, respectively, the
"DESIGNATED BOARD" shall consist of (i) two members designated by
Acacia, (ii) one member designated by Browne, (iii) one member
designated by Schmidt, and (iv) one member elected by the
Company's shareholders voting independently.  In the event of any
vacancy on the Board of Directors, Acacia, Browne and Schmidt
covenant and agree that each shall vote all of their Stock in
accordance with the procedure described above in order to fill
such vacancy.  The Company, Acacia, Browne and Schmidt hereby
agree that the size of the Board of Directors shall not be
increased or decreased without the prior written consent of each
of Browne, Schmidt and Acacia.

          1.2  BOARD APPROVAL OF CERTAIN ACTIONS.  Each of the
Company, Acacia, Browne and Schmidt hereby agrees that each of
the following actions shall require (i) that a majority of the
Company's Board of Directors approve the action, (ii) that such
majority shall at a minimum include either the Browne designee or
the Schmidt designee to the Company's Board of Directors, and
(iii) that each director, in casting his or her vote on such
action, shall consider whether such action would be fair and
reasonable to the Company and shall consider the best interests
of the Company's shareholders as a whole.

          (i)  Any sale, pledge, assignment (by operation of law
     or otherwise) or other disposition of the Patent; provided
     that the Company may, without such approval, grant
     non-exclusive licenses for the use of the Patent to third
     parties on terms and conditions that are fair to the
     Company.

          (ii) Any transaction of merger or consolidation, or
     liquidation, winding-up or dissolution of the Company, or
     conveyance, sale, lease or sub-lease (as lessor or
     sub-lessor), transfer or other disposition of, in one
     transaction or a series of transactions, all or
     substantially all of the Company's business, property or
     assets, whether now owned or hereafter acquired.

          (iii) Any transaction (including, without limitation,
     the purchase, sale, lease or exchange of any property or 
     the rendering of any service) with any officer, director or
     holder of 5% or more of any class of equity securities of
     the Company or with any affiliate of the Company or of any
     such officer, director or holder; provided that the Company
     may, without the unanimous approval of the Board of
     Directors, pay reasonable and customary fees to non-employee
     members of the Board of Directors.

          (iv)  Any issuance of additional shares of Common Stock
     or other equity of the Company (including, without
     limitation, preferred stock, options, warrants, convertible
     debentures, and similar instruments).

          (v)  Any amendment, repeal or alteration in any way of
      any provision of the Certificate of Incorporation or Bylaws
      of the Company.


          TRANSFER OF SHARES.

          2.1  PERMITTED TRANSFERS.  (a)  Acacia, Browne and
Schmidt may sell or otherwise transfer Stock, in accordance with
the terms and conditions of this Agreement, in a transaction that
is a bona fide sale for value in which the transferor and any
affiliate parts with their economic and voting interests in such
Stock (each, a "Bona Fide Transaction").  Stock sold in a Bona
Fide Transaction will not be subject to this Agreement so long as
the sale is otherwise permitted under this Agreement.

          (b)  No party hereto may sell or otherwise transfer
Stock in a transaction that is not a Bona Fide Transaction unless

dividend rights), unless and until the transferring party has
satisfied the requirements of this Section2 with respect to such
sale, assignment or other transfer.  The transferring party shall
provide the Company with written evidence that the requirements
of this Section2 have been or will be met or waived by the
Company and the non-transferring party prior to consummating any
sale, assignment or other transfer of shares of Common Stock, and
no shares of Common Stock shall be transferred on the books of
the Company until such written evidence has been received by the
Company.
