                                SIPEX CORPORATION

                       1.5% CONVERTIBLE SECURED NOTE DUE JUNE 30, 2007

          No. 2003-1      U.S. $10,560,000

                 1.       SECURITY.

                 This Security is a duly authorized 1.5% Convertible Secured
          Note due June 30, 2007 of Sipex Corporation, a Massachusetts
          corporation (the "Company"). Capitalized terms used and not otherwise
          defined herein, shall have the respective meanings given to those
          terms in Section 10 hereof.

                 2.       PRINCIPAL AMOUNT AND INTEREST.

                          (a) The Company for value received, hereby promises
          to pay to the order of Alonim Investments Inc., an Affiliate of Future
          Electronics Inc. ("Future Electronics"), or its registered assigns,
          the principal sum of U.S. $10,560,000 (the "Principal Amount") on June
          30, 2007 (the "Final Maturity Date"). Except as specifically set forth
          in this Security, the Company does not have any right, option, or
          obligation to pay any portion of the principal at any time prior to
          the Final Maturity Date. The Company also undertakes to pay to the
          Holder, interest, at the rate of 1.5% per annum, calculated and
          payable quarterly. Interest shall accrue as and from the date that the
          purchase price of this Security is paid by the Holder to the Company
          (or to an agreed upon escrow agent, as the case may be).

                          (b) Interest shall be computed on the basis of a 365
          day year, and actual days elapsed. Interest shall be payable in U.S.
          Dollars to the Holder in whose name this Security was registered at
          the close of business on the business day

<PAGE>

          immediately preceding an Interest Payment Date (as defined below). The
          first installment of interest shall be due and payable on September
          30, 2003, and successive installments of interest shall be due and
          payable on the last day of every third calendar month thereafter,
          provided, however, that if such day is not a Business Day, the
          interest shall be due and payable on the Business Day immediately
          following such day (each such date, an "Interest Payment Date").

                          (c) Payment of the Principal Amount of this Security
          shall be made upon the surrender of this Security to the Company, at
          the office designated by the Company for delivery of notices pursuant
          to Section 11(a) hereof (the "Designated Office"), in such coin or
          currency of the United States of America as at the time of payment
          shall be legal tender for the payment of public and private debts.

                          (d) Payment of the Principal Amount, and interest,
          shall be made by wire transfer of immediately available funds to the
          Holder entitled thereto in accordance with the wire transfer
          instructions provided by the Holder to the Company at least three
          Business Days prior to the Final Maturity Date or, if no such
          instructions have been so provided, by U.S. dollar check mailed to the
          address of the Holder entitled thereto as such address shall appear in
          the Note Register.

                          (e) Notwithstanding Section 2 (a), on July 31,
          2005, and again on July 31, 2006, the Holder shall have the right to
          receive, on each such occasion, the repayment of up to $3,000,000;
          provided, that the Holder shall have given to the Company at least
          ninety (90) days prior notice of such demand for partial repayment.
          Upon making any such partial repayment, the Company shall deliver to
          the Holder, upon presentation hereof, a new Security reflecting the
          revised Principal Amount.

                 3.       CONVERSION.

                 This Note shall be convertible into shares of Common Stock on
          the terms and conditions set forth in this Section 3, subject to
          vesting of the conversion rights ("Conversion Rights") granted herein,
          as provided for in Section 5 hereof.

                          (a) (1) Subject to compliance with applicable laws,
          including but not limited to the Hart-Scott-Rodino Antitrust
          Improvements Act of 1976, as amended, the provisions of Section
          4(a)(1) and Section 5, the Holder of this Security may, on one or more
          occasions, convert the Principal Amount of this Security (or any
          portion thereof) into Common Stock at any time following the date on
          which any of the Conversion Rights vest, but prior to the close of
          business on June 30, 2007, at the Conversion Price then in effect. The
          number of shares of Common Stock into which all or any portion of the
          Principal Amount may be converted upon any such conversion shall be a
          number of shares equal to the quotient (rounded down to the nearest
          whole share) obtained by dividing (A) the Principal Amount or portion
          thereof being converted by (B) the Conversion Price then in effect;
          provided that the Holder shall be entitled to receive upon such
          conversion only that number of shares of Common Stock equal to the (x)
          number of Conversion Rights which are then vested pursuant to the
          provisions of Section 5 (subject to any adjustments of the number of
          Conversion Rights required to reflect the

                                       2
<PAGE>

          adjustments to the Conversion Price as per Section 3(b) (8)), less (y)
          the aggregate number of shares of Common Stock received pursuant to
          any previous conversion or conversions under this Security.

                 Subject to the other provisions of this Agreement pertaining to
          adjustment of the Conversion Price (as defined below), the rate at
          which the Principal Amount may be converted into Common Stock (the
          "Conversion Price"), upon vesting of the Conversion Rights, shall be
          equal to the weighted average Closing Price of the Common Stock, for
          the twenty Trading Days immediately preceding the approval of the
          instant transaction by the Company's Board of Directors, $3.52. To
          convert this Security on any date after the vesting of the Conversion
          Rights, or any portion thereof (the date of each such conversion, a
          "Conversion Date"), the Holder hereof shall: (x) send by facsimile (or
          otherwise deliver) prior to 5:00 p.m., San Francisco time, on such
          date a copy of the fully executed conversion notice in the form
          attached as Exhibit A hereto (the "Conversion Notice") to the Company,
          (y) if required by Section 3(a)(4), surrender this Security to a
          common carrier for delivery to the Company as soon as practicable on
          or following such date (or an indemnification undertaking with respect
          to this Security in the case of its loss, theft or destruction) and
          (z) pay any transfer taxes or other applicable taxes or duties, if
          any, required in connection with the issuance of shares of Common
          Stock in the name of someone other than the Holder. Upon receipt by
          the Company of a facsimile copy of a Conversion Notice from the
          Holder, the Company shall as soon as practicable, but in any event on
          or before the second Business Day following the date of receipt of the
          Conversion Notice, send, via facsimile, a confirmation to the Holder
          and the transfer agent for the Common Stock stating that the
          Conversion Notice has been received, the date upon which the Company
          expects to deliver the Common Stock issuable upon such conversion and
          the name and telephone number of a contact person at the Company
          regarding the conversion. The Company shall not be obligated to issue
          shares of Common Stock upon a conversion unless the Holder complies
          with the foregoing requirements set forth in this paragraph.

                 On or prior to the third Business Day after any Conversion
          Date (the "Share Delivery Date"), the Company shall issue and deliver
          to the Holder or its nominee (x) that number of shares of Common Stock
          issuable upon conversion of the portion of this Security being
          converted and (y) if required pursuant to Section 3(a)(4), a new
          Security in the form hereof representing the balance of the Principal
          Amount hereof not being converted, if any, and (z) if applicable, cash
          in lieu of any fractional shares pursuant to Section 3(a)(5). If the
          Company's transfer agent is participating in DTC's Fast Automated
          Securities Transfer program, and so long as the certificate for the
          Common Stock to be issued upon conversion of this Security is not
          required to bear a legend and the Holder is not then required to
          return such certificate for the placement of a legend thereon and the
          Holder has provided the Company with the information required by DTC
          relating to the DTC account of the Holder or such Holder's nominee,
          the Company shall cause its transfer agent to electronically transmit
          the Common Stock issuable upon conversion to the Holder by crediting
          the account of the Holder or its nominee with DTC through its Deposit
          Withdrawal Agent Commission system. If the aforementioned conditions
          for a DTC Transfer are not satisfied, the Company shall deliver to the
          Holder physical certificates representing the Common Stock issuable
          upon

                                       3

<PAGE>

          conversion. Further, even if the aforementioned conditions to a DTC
          Transfer are satisfied, the Holder may instruct the Company in writing
          to deliver to the Holder physical certificates representing the Common
          Stock issuable upon conversion in lieu of delivering such shares by
          way of DTC Transfer.

                          (2) The Holder, as such, is not entitled to any
          rights of a holder of Common Stock until the Holder has converted this
          Security into Common Stock, and only to the extent this Security is
          deemed to have been converted into Common Stock pursuant to this
          Section 3.

                          (3) This Security shall be deemed to have been
          converted immediately prior to the close of business on the Conversion
          Date, and at such time the rights of the Holder of this Security as
          the Holder hereof shall cease with respect to the portion of this
          Security converted on such Conversion Date, and the Person or Persons
          entitled to receive the shares of Common Stock issuable upon
          conversion shall be deemed to be a stockholder of record on the
          Conversion Date; provided, however, that no surrender of this Security
          on any date that is not a Business Day shall be effective to
          constitute the person or persons entitled to receive the shares of
          Common Stock upon such conversion as the record holder or holders of
          such shares of Common Stock on such date, but such surrender shall be
          effective to constitute the person or persons entitled to receive such
          shares of Common Stock as the record holder or holders thereof for all
          purposes at the opening of business on the next succeeding Business
          Day.

                          (4) Upon conversion of any portion of this Security
          in accordance with the terms hereof, or upon partial repayment
          pursuant to Section 2(e), the Holder shall physically surrender this
          Security to the Company, upon receipt by the Holder from the Company
          of the shares of Common Stock (or partial repayment, as the case may
          be) and replacement Security showing the revised Principal Amount.

                          (5) The Company will not issue fractional shares of
          Common Stock upon conversion of this Security. In lieu thereof, the
          Company will pay an amount in cash for the current market value of the
          fractional shares. The current market value of a fractional share
          shall be determined (calculated to the nearest 1/1000th of a share) by
          multiplying the Closing Price of the Common Stock on the Trading Day
          immediately prior to the Conversion Date by such fractional share and
          rounding the product to the nearest whole cent.

                          (6) The Company shall, if the Holder so elects,
          deliver the Common Stock issuable upon conversion of this Security to
          any third party designated by the Holder, subject to compliance with
          Sections 3(e) and 11(b) hereof.

                 (b) The Conversion Price will be  subject to adjustments from
          time to time as follows:

                          (1) In case the Company shall hereafter pay a
          dividend or make a distribution to all holders of the outstanding
          Common Stock in shares of Common Stock or rights, options or warrants
          for Common Stock, the Conversion Price in effect on

                                      4

<PAGE>

          the day following the Record Date shall be reduced by multiplying such
          Conversion Price by a fraction:

                                   (A) the numerator of which shall be the
          number of shares of Common Stock outstanding at the close of business
          on the Record Date fixed for the determination of the holders entitled
          to such dividend or distribution; and

                                   (B) the denominator of which shall be the
          sum of such number of shares referred to in (A) above and the total
          number of shares constituting such dividend or other distribution.

                 Such reduction in the Conversion Price shall become effective
          immediately after the opening of business on the day following the
          Record Date.

                          (2) In case the outstanding shares of Common Stock
          shall be subdivided into a greater number of shares of Common Stock,
          the Conversion Price in effect on the day following the day upon which
          such subdivision becomes effective shall be proportionately reduced,
          and conversely, in case the outstanding shares of Common Stock shall
          be combined into a smaller number of shares of Common Stock, the
          Conversion Price in effect at the opening of business on the day
          following the day upon which such combination becomes effective shall
          be proportionately increased, such reduction or increase, as
          applicable, to become effective immediately after the opening of
          business on the day following the day upon which such subdivision or
          combination becomes effective.

                          (3) The Company may make such reductions in the
          Conversion Price, in addition to those required by Sections 3(b)(1) or
          (2) as the Board of Directors considers to be advisable to minimize
          any income tax to holders of Common Stock or rights to purchase Common
          Stock resulting from any dividend or distribution of stock (or rights
          to acquire stock) or from any event treated as such for income tax
          purposes or otherwise.

                          (4) To the extent permitted by applicable law,
          the Company from time to time may reduce the Conversion Price by any
          amount for any period of time if the period is at least 20 days and
          the reduction is irrevocable during the period and the Board of
          Directors determines in good faith that such reduction would be in the
          best interests of the Holder, which determination shall be conclusive
          and set forth in a Board Resolution. Whenever the Conversion Price is
          reduced pursuant to the preceding sentence, the Company shall mail to
          the Holder of this Security, at the Holder's address as it appears in
          the Note Register, a notice of the reduction at least 15 days prior to
          the date the reduced Conversion Price takes effect, and such notice
          shall state the reduced Conversion Price and the period during which
          it will be in effect. In the event that the Company elects to
          temporarily reduce the Conversion Price pursuant to this Section
          3(b)(4), the Conversion Price shall be adjusted upon the expiration of
          such temporary reduction to the Conversion Price that otherwise would
          then be in effect if such temporary reduction had not occurred, and
          the Conversion Price shall at no time be

                                       5

<PAGE>

          greater than the Conversion Price that otherwise would be in effect if
          such temporary reduction had not occurred.

                          (5) No adjustment in the Conversion Price shall be
          required unless such adjustment would require an increase or decrease
          of at least 1% in such price; provided, however, that any adjustments
          which by reason of this Section 3(b)(5) are not required to be made
          shall be carried forward and taken into account in any subsequent
          adjustment. All calculations under this Section 3 shall be made by the
          Company in good faith and shall be made to the nearest cent or to the
          nearest one hundredth of a share, as applicable. No adjustment need be
          made for a change in the par value or no par value of the Common
          Stock.

                          (6) Whenever the Conversion Price is adjusted as
          provided in Section 3(b), the Company shall compute the adjusted
          Conversion Price in accordance with Section 3(b) and shall prepare a
          certificate signed by an executive officer of the Company setting
          forth the adjusted Conversion Price and showing in reasonable detail
          the facts upon which such adjustment is based, and shall mail such
          certificate to the Holder of this Security at its last address in the
          Note Register within 5 Business Days of the effective date of such
          adjustment. Neither the failure to deliver such notice nor the
          existence of any defect therein shall affect the legality or validity
          of any such adjustment.

                          (7) For purposes hereof, "Record Date" shall
          mean, with respect to any dividend, distribution or other transaction
          or event in which the holders of Common Stock have the right to
          receive any cash, securities or other property or in which the Common
          Stock (or other applicable security) is exchanged for or converted
          into any combination of cash, securities or other property, the date
          fixed for determination of stockholders entitled to receive such cash,
          securities or other property (whether such date is fixed by the Board
          of Directors or by statute, contract or otherwise).

                          (8) Whenever the Conversion Price shall be adjusted
          pursuant to Section 3(b), the number of vested and unvested Conversion
          Rights shall thereupon be adjusted so that the then unexercised
          Conversion Rights shall represent the right to conversion into that
          number of shares of Common Stock (calculated to the nearest hundredth
          of a share of Common Stock) obtained by multiplying the Conversion
          Price then in effect immediately prior to such adjustment by the
          number of shares of Common Stock into which such then unexercised
          Conversion Rights may be converted immediately prior to such
          adjustment and dividing the product so obtained by the Conversion
          Price in effect after such adjustment. Any such adjustment to the
          Conversion Rights shall be set forth in the certificate required by
          Section 3(b)(6) with respect to adjustments of the Conversion Price.

                 (c) In case at any time after the date hereof:

                          (1) the Company shall declare a dividend (or any
          other distribution) on its Common Stock that would result in an
          adjustment to the Conversion Price pursuant to this Section 3;

                                       6

<PAGE>

                          (2) the Company shall authorize the granting to the
          holders of its Common Stock of rights or warrants to subscribe for or
          purchase any shares of capital stock of any class (or of securities
          convertible into shares of capital stock of any class) or of any other
          rights;

                          (3) there shall occur any reclassification of the
          Common Stock of the Company (other than a subdivision or combination
          of its outstanding Common Stock, a change in par value, a change from
          par value to no par value or a change from no par value to par value),
          or any merger, consolidation, statutory share exchange or combination
          to which the Company is a party and for which approval of any
          stockholders of the Company is required, or the sale, transfer or
          conveyance of all or substantially all of the assets of the Company;
          or
                          (4) there shall occur the voluntary or involuntary
          dissolution, liquidation or winding up of the Company;

          the Company shall cause to be provided to the Holder of this Security
          in accordance with Section 11(a), at least 20 days (or 10 days in any
          case specified in clause (1) or (2) above) prior to the applicable
          record or effective date hereinafter specified, a written notice
          (which notice shall not include any material non-public information)
          stating:

                                   (A) the date on which a record is to be
          taken for the purpose of such dividend, distribution, grant of rights
          or warrants, or, if a record is not to be taken, the date as of which
          the holders of shares of Common Stock of record to be entitled to such
          dividend, distribution, rights or warrants are to be determined; or

                                   (B) the date on which such reclassification,
          merger, consolidation, statutory share exchange, combination, sale,
          transfer, conveyance, dissolution, liquidation or winding up is
          expected to become effective, and the date as of which it is expected
          that holders of shares of Common Stock of record shall be entitled to
          exchange their shares of Common Stock for securities, cash or other
          property deliverable upon such reclassification, merger,
          consolidation, statutory share exchange, sale, transfer, dissolution,
          liquidation or winding up.

                 Neither the failure to give such notice nor any defect therein
          shall affect the legality or validity of the proceedings or actions
          described in clauses (1) through (4) of this Section 3(c).

                 (d) The Company shall use its best efforts to obtain
          shareholder approval at the next annual meeting of shareholders
          scheduled for May 30, 2003 (the "2003 Meeting") to increase authorized
          capital stock by an amount sufficient for Company to have enough
          shares authorized, un-issued and un-reserved to reserve sufficient
          numbers of shares of Common Stock for the purposes of effecting the
          conversion of this Security. Notwithstanding the foregoing, in the
          event that the Company does not obtain approval for the increase in
          the authorized capital stock at the 2003 Meeting, the Company shall
          use its best efforts to ensure the reservation of sufficient shares of
          Common Stock by decreasing the number of shares of Common

                                       7

<PAGE>

          Stock reserved for future grants of options to purchase the Company's
          Common Stock. If the Company has been unable to reserve sufficient
          shares of Common Stock within six (6) months following the date of the
          2003 Meeting, the Holder shall have the right to require the Company
          to repay to the Holder a pro-rata amount of the Principal Amount of
          this Security, based on the number of shares of Common Stock that have
          not been reserved for conversion of this Security as of such date, and
          the Company shall repay such portion of the Principal Amount, and
          accrued interest calculated as at the date of repayment, within thirty
          (30) days of a notice to that effect from the Holder. In the event of
          such partial repayment, the number of Conversion Rights that can vest
          pursuant to this Security shall be reduced by such amount repaid,
          provided however, that if certain Conversion Rights are no longer
          capable of vesting, the shortfall shall be first allocated against
          these Conversion Rights that can no longer vest. The Company covenants
          that all shares of Common Stock that may be issued upon conversion of
          this Security will upon issue be free from preemptive rights and
          validly issued, fully paid and nonassessable.

                 (e) Except as provided in the next sentence, the Company will
          pay any and all taxes (other than taxes on income) and duties that may
          be payable in respect of the issue or delivery of Common Stock upon
          conversion of this Security. The Company shall not, however, be
          required to pay any tax or duty that may be payable in respect of any
          transfer involved in the issue and delivery of Common Stock in a name
          other than that of the Holder of this Security, and no such issue or
          delivery shall be made unless and until the Person requesting such
          issue has paid to the Company the amount of any such tax or duty, or
          has established to the reasonable satisfaction of the Company that
          such tax or duty has been paid.

                 (f) If any of following events occur:

                          (1) any reclassification or change of the outstanding
          shares of Common Stock (other than a change in par value, or from par
          value to no par value, or from no par value to par value, or as a
          result of a subdivision or combination), as a result of which holders
          of Common Stock shall be entitled to receive Capital Stock, securities
          or other property or assets (including cash) with respect to or in
          exchange for such Common Stock;

                          (2) any merger, consolidation, statutory share
          exchange or combination of the Company with another Person as a result
          of which holders of Common Stock shall be entitled to receive stock,
          securities or other property or assets (including cash) with respect
          to or in exchange for such Common Stock; or

                          (3) any sale or conveyance of the properties and
          assets of the Company as, or substantially as, an entirety to any
          other Person as a result of which holders of Common Stock shall be
          entitled to receive stock, securities or other property or assets
          (including cash) with respect to or in exchange for such Common Stock,
          then the Company or the successor or purchasing entity, as applicable,
          shall execute with the Holder of this Security a supplemental
          agreement providing that this Security shall be convertible into the
          kind and amount of shares of capital stock and other securities or
          property or assets (including cash) that such Holder would have been
          entitled to receive

                                       8

<PAGE>

          upon such reclassification, change, merger, consolidation, statutory
          share exchange, combination, sale or conveyance had this Security been
          converted into Common Stock immediately prior to such
          reclassification, change, merger, consolidation, statutory share
          exchange, combination, sale or conveyance assuming the Holder, as a
          holder of Common Stock, did not exercise its rights of election, if
          any, as to the kind or amount of securities, cash or other property
          receivable upon such reclassification, change, merger, consolidation,
          statutory share exchange, combination, sale or conveyance (provided
          that, if the kind or amount of securities, cash or other property
          receivable upon such reclassification, change, merger, consolidation,
          statutory share exchange, combination, sale or conveyance is not the
          same for each of the shares of Common Stock in respect of which such
          rights of election shall not have been exercised ("Non-Electing
          Share"), then for the purposes of this Section 3(f) the kind and
          amount of securities, cash or other property receivable upon such
          reclassification, change, merger, consolidation, statutory share
          exchange, combination, sale or conveyance for each Non-Electing Share
          shall be deemed to be the kind and amount so receivable per share by a
          plurality of the Non-Electing Shares). Such supplemental agreement
          shall provide for adjustments that shall be as nearly equivalent as
          may be practicable to the adjustments provided for in this Section 3.
          If, in the case of any such reclassification, change, merger,
          consolidation, statutory share exchange, combination, sale or
          conveyance, the stock or other securities and assets receivable
          thereupon by a holder of Common Stock includes shares of stock or
          other securities and assets of a person other than the successor,
          purchasing or transferee entity, as applicable, in such
          reclassification, change, merger, consolidation, statutory share
          exchange, combination, sale or conveyance, then such supplemental
          agreement shall also be executed by such other person and shall
          contain such additional provisions to protect the interests of the
          Holder as the Board of Directors shall reasonably consider necessary
          by reason of the foregoing.

                 The above provisions of this Section 3(f) shall apply to
          successive or a series of related reclassifications, changes, mergers,
          consolidations, statutory share exchanges, combinations, sales and
          conveyances. If this Section 3(f) applies to any event or occurrence,
          then the other provisions of Section 3(b) shall not apply to the
          issuance of securities pursuant to such event or occurrence, provided
          that such other provisions shall continue to apply to all other
          issuances.

                          (g) The Company (i) will effect all registrations
          with, and obtain all approvals by, all governmental authorities that
          may be necessary under any United States federal or state law
          (including the Securities Act, the Exchange Act and state securities
          and Blue Sky laws) for the Common Stock issuable upon conversion of
          this Security to be lawfully issued and delivered as provided herein,
          and thereafter publicly traded (if permissible under the Securities
          Act) and qualified or listed as contemplated by clause (ii) (it being
          understood that the Company shall not be required to register the
          Common Stock issuable on conversion hereof under the Securities Act
          except pursuant to the registration rights contained in Section 4 of
          the Purchase Agreement); and (ii) will list the Common Stock required
          to be issued and delivered upon conversion of this Security, within 30
          calendar days after the first anniversary of the Issuance Date, on
          each national securities exchange on which outstanding Common Stock is
          listed or quoted at such time of such delivery, or if the Common Stock
          is not then listed on any national securities

                                       9

          exchange, to qualify the Common Stock for quotation on the Nasdaq
          Stock Market or such other inter-dealer quotation system, if any, on
          which the Common Stock is then quoted.

                 4.       CONVERSION OR REPAYMENT AT THE OPTION OF THE HOLDER
          UPON A CHANGE OF CONTROL.

                          (a) Conversion Rights and Repayment.

                                   (1) Notwithstanding the fact that certain
          Conversion Rights may have not yet then vested, in the event that a
          Change of Control shall occur at any time prior to the Final Maturity
          Date, then all Conversion Rights that have yet to vest and remain
          eligible for vesting pursuant to Section 5 hereof, shall immediately
          become vested, and, the Holder of this Security shall have the right,
          at the Holder's option, but subject to the provisions of Sections 4(b)
          and 4(c), to convert the Principal Amount of this Security into Common
          Stock at the Conversion Price then in effect, on the terms and
          conditions of Section 3.

                                   (2) In the event that a Change of Control
          shall occur at any time that this Security is outstanding the Holder
          of this Security shall have the right (such right, together with the
          Conversion Rights described above under Section 4(a)(1), the "Change
          of Control Right"), at the Holder's option, but subject to the
          provisions of Sections 4(b) and 4(c), to elect to require that the
          Company repay the entire outstanding Principal Amount of this
          Security, together with all accrued and unpaid interest thereon up to,
          but excluding the day on which the Change of Control is consummated.

                          (b) No sooner than 15 days nor later than 10 days
          prior to the expected date of consummation of a Change of Control, but
          in no event prior to the public announcement of such Change of
          Control, the Company shall deliver written notice thereof via
          facsimile and overnight courier to the Holder (a "Change of Control
          Notice"). The Change of Control Notice shall include a form of
          Conversion Notice and a form of Notice of Election to Require
          Redemption, to be completed by the Holder and delivered to the Company
          pursuant to this Section 4(c), and shall state the following:

                                   (1) that it is a Change of Control Notice
          pursuant to this Section 4;

                                   (2) the events causing the Change of Control
          and the expected date of such Change of Control; and

                                   (3) the procedures with which such Holder
          must comply to exercise its right to have this Security converted or
          repurchased pursuant to Section 4(a), including the date by which the
          completed Conversion Notice or Notice of Election to Require Repayment
          and this Security must be delivered to the Company in order to have it
          converted or redeemed by the Company pursuant to Section 4(a), the
          address for delivery, the Conversion Price then in effect and any
          adjustments thereto, the amount of accrued and unpaid interest thereon
          as of the expected date of consummation of such

                                       10

<PAGE>

          Change of Control, and that this Security as to which a Conversion
          Notice has been given may be converted.

                 No failure by the Company to give the foregoing Change of
          Control Notice shall limit the Holder's right to exercise its rights
          pursuant to Section 4(a).

                          (c) To exercise a Change of Control Right pursuant to
          Section 4(a), a Holder must deliver to the Company, at its Designated
          Office on or prior to the close of business on the Business Day prior
          to the date on which the Change of Control is consummated, the
          following:

                                   (1) a completed Conversion Notice, the form
          of which is contained in Exhibit A hereto, or a completed Notice of
          Election to Require Repayment, the form of which is contained in
          Exhibit B hereto; and

                                   (2) this Security, with, if the Company so
          requires, due endorsement by, or a written instrument of transfer, in
          form satisfactory to the Company duly executed by, the Holder or such
          Holder's attorney duly authorized in writing.

                          (d) In the event that the Holder becomes entitled to
          convert this Security pursuant to this Section 4, the number of
          Conversion Rights exercisable by the Holder shall be adjusted to
          reflect any adjustment to the Conversion Price relative to the
          Conversion Price that was in effect on the Issuance Date as per
          Section 3(b)(8), which shall be applicable mutatis mutandis.

                 5.       VESTING OF CONVERSION RIGHTS

                          (a) Subject to the Conditions set forth hereafter, the
          Conversion Rights associated with this Security shall vest over a
          period of three (3) years, divided into three (3) periods of twelve
          (12) months each ("Reference Periods") as provided for in this Section
          5. The number of Conversion Rights indicated below with respect to a
          Reference Period shall vest in accordance with the schedule set forth
          below in the event that the Sales (as defined below) to Future
          Electronics for such Reference Period equal or exceed the target
          indicated below for such Reference Period (each, a "Target") and the
          vesting mechanism described in Section 5(c).

                          The Reference Periods, the Target for each Reference
          Period and the number of Conversion Rights subject to vesting with
          respect to each Reference Period are as follows:

          </TABLE>

                 (b) Sales Computation. The sales for a given Reference Period
          ("Sales") shall be computed by taking into account the total
          consideration paid by Future Electronics and its Affiliates to the
          Company, inclusive of any adjustments by way of credit or debit, for
          products purchased by Future Electronics or its Affiliates from the
          Company. For clarification purposes, "Sales" is the amount that the
          Company would be able to report as revenue in its financial results in
          accordance with the revenue recognition rules set forth in the
          Company's most recent Form 10-K filing with the Commission, for the
          fiscal year ended December 31, 2002. More specifically, such rules
          provide that (i) sales made to Future Electronics pursuant to the
          distribution agreement dated as of July 1, 1993 by and between Future
          Electronics and the Company, as the same may be amended from time to
          time, (the "Distribution Agreement"), with return privileges and price
          protection rights, are only recognized as revenue upon resale by the
          Holder to its own customer; and (ii) sales made to Future Electronics
          outside of the Distribution Agreement (i.e. without price protection
          or return rights, other than for product related issues), are
          recognized by the Company as revenue immediately. The Company agrees
          that for the purposes of calculating the sales computation hereof, it
          shall use these revenue recognition rules, and to continue to apply
          these rules on a consistent basis through the end of the last
          Reference Period for which this Security shall be in effect, unless
          the Company has received the prior written consent of Future
          Electronics to such modification.

                 The amount (if any) by which the Sales exceed the Target
          during any given Reference Period shall carry over to the Sales
          computation for successive Reference Periods.

                 (c) Subject to the vesting mechanism described in Section 4,
          Conversion Rights allocated to a given Reference Period can vest
          in one of two ways:

                  1) Direct Vesting: If the Sales to Future Electronics for a
                     given Reference Period are equal to or greater than the
                     Target for such Reference Period (as set forth in Section
                     5(a)), the Conversion Rights for such Reference Period
                     shall vest at the end of such Reference Period; and

                  2) Deferred Vesting:

                     (i) If the Sales to Future Electronics for the first
          Reference Period are less than the applicable Target, but are more
          than $28,000,000, then the unvested Conversion Rights allocated to the
          first Reference Period shall vest at the end of the second Reference
          Period , provided that the aggregate Sales for the first, and second
          Reference Periods, exceed $70,000,000; and

                     (ii) If the Sales to Future Electronics for the second
          Reference Period are less than the applicable Target, but are more
          than $38,000,000, then the

                                       12

          unvested Conversion Rights allocated to the second Reference Period
          shall vest at the end of the third Reference Period, provided that the
          aggregate Sales for the second and third Reference Periods, exceed
          $95,000,000;

                 (d) For greater certainty, the Holder and the Company
          hereby stipulate that once Conversion Rights can no longer vest,
          either through direct vesting or deferred vesting, such Conversion
          Rights shall not vest or be capable of vesting in any other way
          pursuant to any other provision of this Security.

                 (e) In the event that the Holder makes a demand for repayment
          of this Security or part thereof, either pursuant to the Default
          provisions hereof, or upon the Final Maturity Date, or pursuant to
          Section 2(e) some or all of the Conversion Rights shall be forfeited
          upon payment by the Company as provided below:

                  If the demand for repayment is only for part of the Principal
          Amount, or the repayment of this Security is only partial, the
          following principles shall be applicable:

                 1. the Conversion  Rights shall be forfeited on a pro rata
                    basis (the ratio being established by using the amount of
                    the partial repayment as the numerator, and the total amount
                    of the Principal Amount, as the denominator), upon repayment
                    by the Company; and

                 2. for purposes of determining which Conversion Rights have
                    been forfeited as a result of such partial repayment, the
                    Conversion Rights shall be deemed to be forfeited in the
                    following order:

                    i.   Conversion Rights that can no longer vest shall be
                 forfeited first;

                    ii.  Conversion Rights that can no longer vest directly, but
                 can still vest through "deferred vesting" (as described in
                 Paragraph 5 (c)) shall be forfeited second;

                    iii. Conversion Rights that can still vest either through
                 "direct vesting" (as described in Paragraph 5(c)), or deferred
                 vesting, shall be forfeited third; and

                    iv.  Vested Conversion Rights shall be forfeited last.

                 6.       COVENANTS OF THE COMPANY.

                          (a) The Company covenants and agrees that it will duly
          and punctually pay or cause to be paid the Principal Amount, and the
          interest accrued thereon at the respective times and in the manner
          provided for herein.

                          (b) Unless otherwise permitted herein, the
          Company will do or cause to be done all things necessary to preserve
          and keep in full force and effect its existence and the rights
          (charter and statutory) of the Company and each of its Subsidiaries;
          provided, however, that the Company shall not be required to preserve
          any such right with respect to a Subsidiary if the Company shall
          determine in good faith that the preservation thereof is no longer
          desirable in the conduct of the business of the Company

                                       13

<PAGE>
          and its Subsidiaries as a whole and that the loss thereof is not
          disadvantageous in any material respect to the Holder.

                          (c) The Company covenants and agrees that it shall,
          at all times during the term hereof and until the Final Maturity Date,
          comply with the financial tests set forth in Schedule "A" hereto, and
          that it shall:

                                    (i) on a quarterly basis, within five (5)
          business days of the release and disclosure of its most recent
          financial information, provide the Holder with a certificate signed by
          its Chief Financial Officer, attesting that the Company has been
          meeting the said financial tests, since the Issuance Date, or the date
          of the last such certificate, as the case may be; and

                                    (ii) within ten (10) business days of the
          Company not meeting any of the financial tests set forth in Schedule
          "A", the Company shall notify the Holder of such event, and provide
          the Holder with the reasons for such non-compliance, as well as the
          particulars of the Company's proposed remedial action, in respect of
          such non-compliance.

                          (d) The Company and its Affiliates, shall not,
          without the prior approval of the Holder, which may be withheld at the
          Holder's discretion acting reasonably and in good faith, enter into
          any contracts or agreements, or subscribe any obligations, the result
          of which would be to increase existing Indebtedness, or create new
          Indebtedness, amounting to $2,000,000, in the aggregate.

                 7.       EVENTS OF DEFAULT.

                          (a) "Event of Default", wherever used herein, means

          contained in this Security, the Purchase Agreement or the Deed of
          Trust and, in any case, the default continues for a period of 30 days
          after written notice of such failure, requiring the Company to remedy
          the same, shall have been given to the Company by the Holder or in the
          event of a material breach of any representations or warranties of the
          Company in this Security, the Purchase Agreement or the Deed of Trust;

          been discharged within 30 days or (B) defaults with respect to any
          Instrument, which default permits or results in the acceleration of

          rescinded or annulled within 30 days;

<PAGE>

          or relief under any applicable U.S. federal or state law, or the
          consent by the Company or any Subsidiary of the Company to the filing
          of such petition or to the appointment of or the taking of possession
          by a custodian, receiver, liquidator, assignee, trustee, sequestrator

          generally as they become due, or the taking of corporate action by the
          Company or any Subsidiary of the Company expressly in furtherance of
          any such action.

                 A default under clause (5) above is not an Event of Default
          until the Holder notifies the Company of the default and, if
          applicable, the Company does not cure such default (and such default
          is not waived) within the time specified in clause (5) above after
          actual receipt of such notice. Any such notice must specify the
          default, if applicable demand that it be remedied, and state that such
          notice is a "Notice of Default".

                          (b) If an Event of Default (other than an Event of
          Default specified in Sections 7(a)(7) or 7(a)(8) hereof with respect
          to the Company) occurs and is continuing, the Holder, by written
          notice to the Company, may declare due and payable, in whole or in
          part, in its unfettered and absolute discretion, the Principal Amount
          , as well as any interest accrued on this Security to the date of
          payment. Upon a declaration of acceleration, such Principal Amount (or
          part thereof, as the case may be) and accrued and unpaid interest to
          the date of payment, shall be immediately due and payable.

                 On the occurrence and during the continuance of any Event
          of Default, in addition to and without limitation of the other rights
          of the Holder hereunder, (i) all Conversion Rights, which have not yet
          vested and remain eligible to vest pursuant to Section 5 hereof, shall
          immediately and automatically vest, and (ii) the provisions of this
          Security pertaining to adjustment of the Conversion Price and
          corresponding number of Conversion Rights shall apply mutatis
          mutandis.

                 If an Event of Default specified in Section 7(a)(7) and 7(a)(8)
          occurs with respect to the Company, the Principal Amount and accrued
          and unpaid interest on this Security shall become and be immediately
          due and payable, without any declaration or other act on the part of
          the Holder.

                          (c) If an Event of Default with respect to this
          Security occurs and is continuing, the Holder may pursue any available
          remedy by proceeding at law or in equity (including a decree of
          specific performance and/or other injunctive relief) to collect the
          Defaulted Payment or interest or any other amount due and payable on
          this Security or to enforce the performance of any provision of this
          Security.

                          (d) Notwithstanding any other provision in this
          Security, the Holder of this Security shall have the right, which is
          absolute and unconditional, to receive payment of the Principal Amount
          and accrued interest on or after the respective due dates, to convert
          this Security in accordance with Section 3 or to bring suit for the
          enforcement of any such payment or the right to convert, and such
          rights shall not be impaired or affected

                                       16

<PAGE>

          adversely without the consent of the Holder. Amounts set forth or
          provided for herein with respect to payments, conversion and the like
          (and the computation thereof) shall be the amounts to be received by
          the Holder and shall not, except as expressly provided herein, be
          subject to any other obligation of the Company (or the performance
          thereof).

                          (e) If the Holder of this Security has instituted any
          proceeding to enforce any right or remedy under this Security and such
          proceeding has been discontinued or abandoned for any reason, or has
          been determined adversely to the Holder, then and in every such case,
          subject to any determination in such proceeding, the Company and the
          Holder shall be restored severally and respectively to their former
          positions hereunder and thereafter all rights and remedies of the
          Holder shall continue as though no such proceeding had been
          instituted.

                          (f) Except as otherwise provided herein, no right or
          remedy conferred in this Security upon the Holder is intended to be
          exclusive of any other right or remedy available to the Holder under
          this Security, the Warrant, the Purchase Agreement, and the Deed of
          Trust and every right and remedy shall, to the extent permitted by
          law, be cumulative and in addition to every other right and remedy
          given hereunder or hereafter existing at law or in equity or
          otherwise. The assertion or employment of any right or remedy
          hereunder, or otherwise, shall not prevent the concurrent assertion or
          employment of any other appropriate right or remedy.

                          (g) The Company covenants (to the extent that it may
          lawfully do so) that it will not at any time insist upon, or plead, or
          in any manner whatsoever claim to take the benefit or advantage of,
          any stay or extension law wherever enacted, now or at any time
          hereafter in force, which may affect the covenants or the performance
          of this Security; and the Company (to the extent that it may lawfully
          do so) hereby expressly waives all benefit or advantage of any such
          law and covenants that it will not hinder, delay or impede the
          execution of any power herein granted to the Holder hereof, but will
          suffer and permit the execution of every such power as though no such
          law had been enacted.

                 8.       CONSOLIDATION, MERGER, ETC.

                          (a) The Company shall not consolidate with or merge
          into any other Person or, directly or indirectly, convey, transfer,
          sell or lease its properties and assets as, or substantially as, an
          entirety to any Person unless:

                                   (1) In the event that the Company shall
          consolidate with or merge into another Person or convey, transfer,
          sell or lease its properties and assets substantially as an entirety
          to any Person, the Person formed by such consolidation or into which
          the Company is merged or the Person which acquires by conveyance,
          transfer or sale, or which leases, all or substantially all of the
          properties and assets of the Company shall be a corporation,
          partnership, limited liability company or other business entity
          organized and validly existing under the laws of the Untied States of
          America, any State thereof or the District of Columbia, which shall,
          prior to or upon the consummation of such transaction, expressly
          assume, if other than the Company, by an agreement

                                     17

          supplemental hereto, executed and delivered to the Holder of this
          Security in form reasonably satisfactory to the Holder, the due and
          punctual payment of the Principal Amount of and any interest on this
          Security and the performance or observance of every covenant of this
          Security on the part of the Company to be performed or observed,

          transaction, no Event of Default, and no event which, after notice or
          lapse of time or both, would become an Event of Default, shall have
          happened and be continuing.

                          (b) Upon any consolidation of the Company with, or
          merger of the Company into, any other Person or any conveyance,
          transfer, sale or lease of all or substantially all of the properties
          and assets of the Company in accordance with Section 8(a), the
          successor Person formed by such consolidation or into which the
          Company is merged or to which such conveyance, transfer, sale or lease
          is made shall succeed to, and be substituted for, and may exercise
          every right and power of, the Company under this Security with the
          same effect as if such successor Person had been named as the Company
          herein, and thereafter, except in the case of a lease, the predecessor
          Person shall be relieved of all obligations and covenants under this
          Security.

                 9.       SECURITY INTEREST. The Company covenants and agrees
          that this Security as well as any replacement Security or other

          been registered under the Securities Act, or any state securities laws
          and, therefore, cannot be resold unless it is registered under the
          Securities Act and applicable state securities laws or unless an
          exemption from such registration requirements is available. The Holder
          is aware that the Company is under no obligation to effect any such
          registration or to file for or comply with any exemption from
          registration. The Holder has not been formed solely for the purpose of
          making this investment and is acquiring the Security for its own
          account for investment, and not with a view to, or for resale in
          connection with, the distribution thereof.

                                   (6) Such Holder understands that:

                                       (A) until the end of the holding
          period under Rule 144(k) of the Securities Act (or any successor
          provision), this Security (and all securities issued in exchange
          therefor or in substitution thereof, other than the shares of Common
          Stock issuable upon conversion of this Security, which shall bear the
          legend set forth in Section 11(b)(6)(B) of this Security, if
          applicable) shall bear a legend in substantially the following form:

               THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
               THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
               SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE,
               SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED IN THE
               ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
               UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
               SECURITIES LAWS OR AN EXEMPTION THEREFROM.

               THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
               TERMS AND CONDITIONS OF A VOTING

               AGREEMENT WHICH PLACES CERTAIN RESTRICTIONS ON THE VOTING OF THE
               SECURITIES REPRESENTED HEREBY. ANY PERSON ACCEPTING ANY INTEREST
               IN SUCH SECURITIES SHALL BE DEEMED TO AGREE TO AND SHALL BECOME
               BOUND BY ALL THE PROVISIONS OF SUCH AGREEMENT. A COPY OF SUCH

               CERTIFICATE WITHOUT CHARGE UPON WRITTEN REQUEST TO THE COMPANY AT
               ITS PRINCIPAL PLACE OF BUSINESS.

          The legend set forth above shall be removed and the Company shall
          issue a new Security of like tenor and aggregate principal amount, and
          which shall not bear the restrictive legend required by this Section
          11(b)(6)(A), (i) if, in connection with a sale transaction, the Holder
          provides the Company with an opinion of counsel reasonably acceptable
          to the Company to the effect that a public sale, assignment, pledge or
          transfer of this Security may be made without registration under the
          Securities Act, or (ii) upon expiration of the applicable two-year
          holding period under Rule 144(k) of the Securities Act (or any
          successor rule). The Company shall not require such opinion of counsel
          for the sale of this Security in accordance with Rule 144 of the
          Securities Act in the event that the Holder provides such
          representations that the Company shall reasonably request confirming
          compliance with the requirements of Rule 144;

                                           (B) until the end of the
          holding period under Rule 144(k) of the Securities Act (or any
          successor provision), any stock certificate representing such shares
          of Common Stock shall bear a legend in substantially the following
          form unless, in the case of shares of Common Stock issued upon
          conversion of this Security, the Security submitted for conversion is
          not required to bear the legend specified in Section 11(b)(6)(A):

               THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
               REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
               APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE
               OFFERED FOR SALE, SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR
               HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
               STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS
               AMENDED, OR AN EXEMPTION THEREFROM.

               THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
               TERMS AND CONDITIONS OF A VOTING AGREEMENT WHICH PLACES CERTAIN
               RESTRICTIONS ON THE VOTING OF THE SECURITIES REPRESENTED HEREBY.
               ANY PERSON ACCEPTING ANY INTEREST IN SUCH SECURITIES SHALL BE
               DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS
               OF SUCH AGREEMENT. A COPY OF SUCH VOTING AGREEMENT WILL BE
               FURNISHED TO THE RECORD HOLDER OF THIS CERTIFICATE WITHOUT

               CHARGE UPON WRITTEN REQUEST TO THE COMPANY AT ITS PRINCIPAL PLACE
               OF BUSINESS.

          The legend set forth above shall be removed and the Company shall
          issue a stock certificate evidencing such shares of Common Stock, as
          the case may be, without such legend to the holder of the stock
          certificate evidencing such shares of Common Stock and upon which such
          legend is stamped, (i) if such shares of Common Stock have been resold
          or transferred pursuant to the registration statement contemplated by
          the Purchase Agreement and the registration statement was effective at
          the time of such transfer, (ii) if, in connection with a sale
          transaction, such holder provides the Company with an opinion of
          counsel reasonably acceptable to the Company to the effect that a
          public sale, assignment, pledge or transfer of the shares of Common
          Stock may be made without registration under the Securities Act, or
          (iii) upon expiration of the applicable two-year holding period under
          Rule 144(k) of the Securities Act (or any successor rule). The Company
          shall not require such opinion of counsel for the sale of such shares
          of Common Stock in accordance with Rule 144 of the Securities Act,
          provided that the Seller provides such representations that the
          Company shall reasonably request confirming compliance with the
          requirements of Rule 144; and

                                           (C) in the event Rule 144(k) as
          promulgated under the Securities Act (or any successor rule) is
          amended to change the two-year holding period under Rule 144(k) (or
          the corresponding holding period under any successor rule), (i) each
          reference in Sections 11(b)(6) of this Agreement to "two-year holding
          period" shall be deemed for all purposes of this Agreement to be
          references to such changed period, and (ii) all corresponding
          references in this Security shall be deemed for all purposes to be
          references to the changed period, provided that such changes shall not
          become effective if they are otherwise prohibited by, or would
          otherwise cause a violation of, the then-applicable federal securities
          laws.

                                   (7) Neither this Security nor any term
          hereof may be amended or waived orally or in writing, except that any
          term of this Security may be amended and the observance of any term of
          this Security may be waived (either generally or in a particular
          instance and either retroactively or prospectively), upon the approval
          of the Company and the Holder; provided, however, that the Company
          may, without the consent of the Holder, amend the Security for the
          purpose of (i) surrendering any right or power conferred upon the
          Company, (ii) providing for Conversion Rights of Holder if any
          reclassification or change of the Common Stock or any consolidation,
          merger or sale of all or substantially all of the Company's assets
          occurs, (iii) providing for the assumption of the Company's
          obligations to the Holder in the case of a merger, consolidation,
          conveyance, transfer or lease, or (iv) reducing the Conversion Price,
          provided that the reduction will not adversely affect the interests of
          the Holder.

                          (c) In any case in which the date of maturity of,
          the date of payment of any interest on this Security will not be a
          Business Day, then payment of such interest on or Principal Amount of
          this Security need not be made on such date, but may be made on the
          next succeeding Business Day with the same force and effect as if made
          on such date

                                       27

<PAGE>

          of maturity or date of payment, as the case may be, and no interest
          shall accrue for the period from and after such date.

                          (d) In the case of a dispute as to the determination
          of the Closing Price, the Conversion Price, the fair market value of
          assets (other than cash or securities), or the arithmetic calculation
          of any shares of Common Stock to be issued hereunder, the Company
          shall submit the disputed determinations or arithmetic calculations
          via facsimile within one Business Day from the manifestation of such
          dispute to the Holder. If the Company and the Holder are unable to
          agree upon such determination or calculation of the Closing Price, the
          Conversion Price or the fair market value of assets (other than cash
          or securities), or the arithmetic calculation of any shares of Common
          Stock to be issued hereunder, as the case may be, within one Business
          Day of such disputed determination or arithmetic calculation being
          submitted to the Holder, then the Company shall, within 10 Business
          Days, submit via facsimile (a) the disputed determination of Closing
          Price, the Conversion Price or the fair market value of assets (other
          than cash or securities) to an independent, reputable investment bank
          selected by the Company and approved by the Holder or (b) the disputed
          arithmetic calculation of any shares of Common Stock to be issued
          hereunder to the Company's independent, outside accountant. The
          Company shall make reasonable efforts to cause the investment bank or
          the accountant, as the case may be, to perform the determinations or
          calculations and notify the Company and the Holder of the results no
          later than 15 Business Days from the date it receives the disputed
          determinations or calculations. Such investment bank's or accountant's
          determination or calculation, as the case may be, shall be binding
          upon all parties absent demonstrable error. The fees and expenses of
          the accountant or investment bank, as the case may be, shall be paid
          by the party whose calculation or determination is, on a percentage
          basis, the least closest to that determined by the accountant or
          investment bank; provided, however, that if each of the amounts
          originally determined or calculated by the Company and the Holder are
          at least equal to 80% of the amount calculated or determined by the
          accountant or investment bank but not more than 120% of the amount
          calculated or determined by the accountant or investment bank, then
          the Company and the Holder will each pay one half of the fees and
          expenses of such accountant or investment bank.

                          (e) If (a) this Security is placed in the hands of
          an attorney for collection or enforcement or is collected or enforced
          through any legal proceeding or the Holder otherwise takes action to
          collect amounts due under this Security or to enforce the provisions
          of this Security or (b) there occurs any bankruptcy, reorganization,
          receivership of the Company or other proceedings affecting Company
          creditors' rights and involving a claim under this Security, then the
          Company shall pay the reasonable costs incurred by the Holder for such
          collection, enforcement or action or in connection with such
          bankruptcy, reorganization, receivership or other proceeding,
          including but not limited to reasonable attorneys fees and
          disbursements.

          IN ACCORDANCE WITH THE LAWS OF THE STATE OF CALIFORNIA.

         exercise such remedies.

                  3B.      Disposition of Common Stock - Unlimited Period.
         In the event that either Alonim and/or any of its Affiliates shall,
         without the prior written consent of the Company, directly or

         incurred by Alonim and/or its Affiliates, provided, that such fees and
         expenses shall not exceed $20,000 in the aggregate; and provided,
         further, that any incremental expenses relating to the registration of
         Affiliate Shares in any registration shall be borne by Alonim;

                                    (viii) advise Alonim promptly after it shall
         receive notice or obtain knowledge of the issuance of any stop order by
         the SEC delaying or suspending the effectiveness of the Registration
         Statement or of the initiation or threat of any proceeding for that
         purpose; and it will promptly use its reasonable best efforts to
         prevent the issuance of any stop order or to obtain its withdrawal at
         the earliest possible moment if such stop order should be issued;

                                    (ix) if an offering of Registrable Shares
         is to be underwritten in whole or in part, enter into a written
         underwriting agreement in form and substance reasonably satisfactory to
         the managing underwriter of the public offering, the Company and
         Alonim;

                                    (x) notify Alonim, promptly after it shall
         receive notice thereof, of the date and time when the Registration
         Statement and each post-effective amendment thereto has become
         effective or a supplement to any prospectus forming a part of the
         Registration Statement has been filed;

                                    (xi) cause all Registrable Shares to be
         listed on each securities exchange or market on which the Common Stock
         is listed;

                                    (xii) make available for inspection upon
         request by Alonim, by any managing underwriter of any distribution to
         be effected pursuant to the Registration Statement and by any attorney,
         accountant or other agent retained by Alonim or any such underwriter,
         all financial and other records, pertinent corporate documents and
         properties of the Company, and cause all of the Company's officers,
         directors and employees to supply all information reasonably requested
         by Alonim or any such underwriter, attorney, accountant or agent in
         connection with the Registration Statement;

                                    (xiii) if such registration includes an
         underwritten public offering, at the closing provided for in the
         underwriting agreement, provide, at Alonim's expense, (A) an opinion
         dated such date of the counsel representing the Company for the
         purposes of such registration, addressed to the underwriters, covering
         such matters with respect to the Registration Statement, the prospectus
         and each amendment or supplement thereto, proceedings under state and
         federal securities laws, other matters relating to the Company, the
         securities being registered and the offer and sale of such securities
         as are customarily the subject of opinions of issuer's counsel provided
         to underwriters in underwritten public offerings, and such opinion of
         counsel

                                       6

<PAGE>

         shall additionally cover such legal matters with respect to the
         registration as Alonim may reasonably request, and (B) letters dated
         each of such effective date and such closing date, from the independent
         certified public accountants of the Company, addressed to the
         underwriters, stating that they are independent certified public
         accountants within the meaning of the Securities Act and dealing with
         such matters as the underwriters may request, or if the offering is not
         underwritten that in the opinion of such accountants the financial
         statements and other financial data of the Company included in the
         registration statement or the prospectus or any amendment or supplement
         thereto comply in all material respects with the applicable accounting
         requirements of the Securities Act, and additionally covering such
         other accounting and financial matters, including information as to the
         period ending not more than five (5) business days prior to the date of
         such letter with respect to the Registration Statement and Prospectus,
         as Alonim may reasonably request; and

                                    (xiv) subject to all the other provisions
         of this Agreement, take all other commercially reasonable steps
         necessary to effect any registration of Registrable Shares contemplated
         hereby.

                           (b) Piggyback Rights on Company Registration.

                                    (i) If the Company shall determine to
         register any of its securities either for its own account or the
         account of a security holder or holders exercising their respective
         demand registration rights (other than pursuant to Section 4 hereof),
         other than a registration relating solely to employee benefit plans, a
         registration relating solely to the offer and sale of debt securities,
         a registration relating solely to a corporate reorganization or other
         transaction subject to Rule 145 on Form S-4, a registration on any
         registration form that does not permit secondary sales (any such
         registration, a "Company Registration"), the Company shall:

                                           (A) promptly give to Alonim written
         notice thereof;

                                           (B) use its commercially reasonable
         efforts to include in such registration (and any related qualification
         under blue sky laws or other compliance), except as set forth in
         Section 4(b)(ii) below, and in any underwriting involved therein, the
         Additional Registrable Securities specified in a written request or
         requests made by Alonim and received by the Company within fifteen (15)
         days after the written notice from the Company described in clause (i)
         above is received by Alonim, which written request may specify all or a
         part of the Registrable Securities held by Alonim; and

                                           (C) comply with all the provisions of
         Section 4(a)(iii) through (a)(xiv) in connection with any such
         registration.

                                    (ii) If the registration of which the
         Company gives notice is for a registered public offering involving an
         underwriting, the Company shall so advise Alonim as a part of the
         written notice given pursuant to Section 4(b)(i). In such event, the
         right of Alonim to registration pursuant to this Section 4(b) shall be
         conditioned upon Alonim's participation in such underwriting and the
         inclusion of Additional Registrable Securities held by Alonim in the
         underwriting to the extent provided herein. If Alonim proposes to
         distribute any securities through such underwriting, then it shall
         (together with the Company and the other stockholders that are
         participating in such registration) enter into an underwriting
         agreement in customary form with the representative of the underwriter
         or underwriters selected by the Company. If

                                        7

<PAGE>

         Alonim does not agree to the terms of any such underwriting, then
         Alonim shall be excluded therefrom by notice from the Company or the
         underwriters. Any Additional Registrable Securities or other securities
         excluded or withdrawn from such underwriting shall be withdrawn from
         such registration.

                                    (iii) Notwithstanding any other provision of
         this Section 4(b), in the event that a Company Registration is
         underwritten, if a representative of the underwriters advises the
         Company in writing that marketing factors require a limitation of the
         number of securities to be underwritten (including Additional
         Registrable Securities) in an offering subject to this Section 4(b)
         because the number of securities to be underwritten is likely to have
         an adverse effect on the price, timing or the distribution of
         securities to be offered, then the Company shall so advise Alonim which
         would otherwise be underwritten pursuant hereto, and subject to the
         terms of the registration rights contained in the Stock Purchase
         Agreements dated as of April 15, 2002 (the "Prior Registration
         Agreements") between other stockholders and the Company, the number of
         shares that may be included in the underwriting shall be allocated,
         first, to the Company, second, to Alonim and, third, to the other
         stockholders in accordance with the Prior Registration Agreements. Any
         Registrable Securities or other securities excluded or withdrawn from
         such underwriting shall be withdrawn from such registration. If the
         underwriting agreement executed in connection with such offering
         provides for an overallotment option to be granted to the underwriters,
         and if such option is exercised by the underwriters, the allocation
         priority established above shall govern the allocation with respect to
         the sale of any shares of securities (including Registrable Securities)
         pursuant to such exercise by the underwriters. No such reduction
         pursuant to this Section 4(b)(iii) shall reduce the amount of
         Additional Registrable Securities of Alonim included in the
         registration below twenty-five percent (25%) of the total amount of
         securities included in such registration.

                                    (iv) The Company shall have the right to
         terminate or withdraw any registration described under this Section
         4(b) prior to the effectiveness of such registration whether or not
         Alonim has elected to include Additional Registrable Securities in such
         registration. The registration expenses of such withdrawn registration
         shall be borne by the Company in accordance with Section 4(a) hereof.

                           (c) Transfer of Registrable Shares After
          Registration; Suspension.

                                    (i) Each of Alonim and each of its
         Affiliates agrees that it will not effect any disposition of the
         Registrable Shares under the Registration Statement referred to in
         Section 4(a) above except as contemplated in such Registration
         Statement and as described herein or as otherwise permitted by law, and
         that it will promptly notify the Company of any changes in the
         information set forth in the Registration Statement regarding Alonim
         and its Affiliates or its plan of distribution; provided, however, that
         nothing in this section shall in any way limit Alonim's and its
         Affiliates' ability to transfer or otherwise dispose of any of the
         Securities as permitted by any other section of this Agreement and
         applicable law.

                                    (ii) Except in the event that paragraph
         (iii) below applies, the Company shall (A) prepare and file from time
         to time with the SEC a post-effective amendment to the Registration
         Statement or a supplement to the related Prospectus or a supplement or
         amendment to any document incorporated therein by reference or file any
         other required document so that such Registration Statement will not
         contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the

                                       8

<PAGE>

         statements therein not misleading, and so that, as thereafter delivered
         to purchasers of the Registrable Shares being sold thereunder, such
         Prospectus will not contain an untrue statement of a material fact or
         omit to state a material fact required to be stated therein or
         necessary to make the statements therein, in light of the circumstances
         under which they were made, not misleading; (B) provide Alonim copies
         of any documents filed pursuant to Section 4(c)(ii); and (C) inform
         Alonim that the Company has complied with its obligations in Section
         4(c)(ii) (or that, if the Company has filed a post-effective amendment
         to the Registration Statement which has not yet been declared
         effective, the Company will notify Alonim to that effect, will use its
         best efforts to secure the effectiveness of such post-effective
         amendment as promptly as possible and will promptly notify Alonim
         pursuant to Section 4(c)(ii) hereof when the amendment has become
         effective).

                                    (iii) In the event (A) of any request by
         the SEC or any other federal or state governmental authority during the
         period of effectiveness of the Registration Statement for amendments or
         supplements to a Registration Statement or related Prospectus or for
         additional information; (B) of the issuance by the SEC or any other
         federal or state governmental authority of any stop order suspending
         the effectiveness of a Registration Statement or the initiation of any
         proceedings for that purpose; (C) of the receipt by the Company of any
         notification with respect to the suspension of the qualification or
         exemption from qualification of any of the Registrable Shares for sale
         in any jurisdiction or the initiation or threatening of any proceeding
         for such purpose; or (D) of any event or circumstance which in the good
         faith judgment of the Company's Board of Directors, upon advice of
         counsel, would necessitate the making of any changes in the
         Registration Statement or Prospectus, or any document incorporated or
         deemed to be incorporated therein by reference, so that, in the case of
         the Registration Statement, it will not contain any untrue statement of
         a material fact or any omission to state a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading, and that in the case of the Prospectus, it will not contain
         any untrue statement of a material fact or any omission to state a
         material fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading; then the Company shall, deliver a
         certificate in writing to Alonim (the "Suspension Notice") to the
         effect of the foregoing and, upon receipt of such Suspension Notice,
         Alonim and its Affiliates will refrain from selling any Registrable
         Shares pursuant to the Registration Statement (a "Suspension") until
         Alonim's and its Affiliates receipt of copies of a supplemented or
         amended Prospectus prepared and filed by the Company, or until it is or
         they are advised in writing by the Company that the current Prospectus
         may be used, and has received copies of any additional or supplemental
         filings that are incorporated or deemed incorporated by reference in
         any such Prospectus. In the event of any Suspension, the Company will
         use its commercially reasonable efforts to cause the use of the
         Prospectus so suspended to be resumed as expeditiously as practicable
         after the delivery of a Suspension Notice to Alonim.

                                    (iv) Provided that a Suspension is not then
         in effect, Alonim and its Affiliates may sell Registrable Shares under
         the Registration Statement, provided that it arranges or they arrange
         for delivery of a current Prospectus to the transferee of such
         Registrable Shares.

                           (d) Indemnification.

                                    (i) For the purpose of this Section 4(d):

                                       9

<PAGE>

                                           (x) the term "Selling Stockholder"
         shall include Alonim and any officer, director or trustee of Alonim,
         any underwriter (as defined in the Securities Act) for Alonim and/or
         any Affiliate of Alonim and each person, if any, that controls Alonim,
         any Affiliate of Alonim and/or any such underwriter within the meaning
         of the Securities Exchange Act of 1934, as amended; and

                                           (y) the term "Registration Statement"
         shall include any final Prospectus, exhibit, supplement or amendment
         included in or relating to the Registration Statement referred to in
         Section 4(a).

                                    (ii) The Company agrees to indemnify and
         hold harmless each Selling Stockholder from and against any losses,
         claims, damages or liabilities to which such Selling Stockholder may
         become subject (under the Securities Act or otherwise) insofar as such
         losses, claims, damages or liabilities (or actions or proceedings in
         respect thereof) arise out of, or are based upon any untrue statement,
         or alleged untrue statement of any material fact contained in a
         Registration Statement, or any omission or alleged omission to state a
         material fact required to be stated in a Registration Statement, or
         necessary to make the statements therein, in light of the circumstances
         in which they were made, not misleading, and the Company will reimburse
         such Selling Stockholder for any reasonable legal or other expenses
         reasonably incurred in investigating, defending or preparing to defend
         any such action, proceeding or claim, provided, however, that the
         Company shall not be liable in any such case to the extent that such
         loss, claim, damage or liability arises out of, or is based upon, (x)
         an untrue statement made or alleged untrue statement or omission or
         alleged omission in such Registration Statement in reliance upon and in
         conformity with written information furnished to the Company by or on
         behalf of such Selling Stockholder specifically for use in preparation
         of the Registration Statement, (y) the failure of such Selling
         Stockholder to comply with its covenants and agreements contained in
         Section 4(c) hereof respecting sale of the Registrable Shares, or (z)
         any statement or omission in any Prospectus that is corrected in any
         subsequent Prospectus that was delivered to Alonim prior to the
         pertinent sale or sales by Alonim.

                                    (iii) Each of Alonim, S & F Financial
         Holding Inc., and Future Electronics Inc. (together the "Signatory
         Affiliates")agree to indemnify and hold harmless the Company (and each
         person, if any, who controls the Company within the meaning of Section
         15 of the Securities Act, each officer of the Company who signs the
         Registration Statement and each director of the Company) from and
         against any losses, claims, damages or liabilities to which the Company
         (or any such officer, director or controlling person) may become
         subject (under the Securities Act or otherwise), insofar as such
         losses, claims, damages or liabilities (or actions or proceedings in
         respect thereof) arise out of, or are based upon, (i) any failure by
         such Alonim to comply with the covenants and agreements contained in
         Section 4(c) hereof respecting sale of the Registrable Shares, or (ii)
         any untrue statement, or alleged untrue statement of any material fact
         contained in a Registration Statement, or any omission or alleged
         omission to state a material fact required to be stated in a
         Registration Statement, or necessary to make the statements therein not
         misleading, if such untrue statement or omission or alleged untrue
         statement or omission was made in reliance upon and in conformity with
         written information furnished by or on behalf of Alonim or the
         Signatory Affiliates specifically for use in preparation of the
         Registration Statement, and Alonim or the Signatory Affiliates will
         reimburse the Company (or such officer, director or controlling
         person), as the case may be, for any reasonable legal or other expenses
         reasonably incurred in investigating, defending or preparing to defend
         any such action, proceeding or claim; provided that Alonim's or the
         Signatory Affiliates

                                       10

<PAGE>

         obligation to indemnify the Company shall be limited to the amount
         received by Alonim or the Signatory Affiliates from the sale of the
         Registrable Shares.

                                    (iv) Promptly after receipt by any
         indemnified person of a notice of a claim or the beginning of any
         action in respect of which indemnity is to be sought against an
         indemnifying person pursuant to this Section 4(d), such indemnified
         person shall notify the indemnifying person in writing of such claim or
         of the commencement of such action, but the omission to so notify the
         indemnifying party will not relieve it from any liability which it may
         have to any indemnified party under this Section 4(d) (except to the
         extent that such omission materially and adversely affects the
         indemnifying party's ability to defend such action) or from any
         liability otherwise than under this Section 4(d). Subject to the
         provisions hereinafter stated, in case any such action shall be brought
         against an indemnified person, the indemnifying person shall be
         entitled to participate therein, and, to the extent that it shall elect
         by written notice delivered to the indemnified party promptly after
         receiving the aforesaid notice from such indemnified party, shall be
         entitled to assume the defense thereof, with counsel reasonably
         satisfactory to such indemnified person. After notice from the
         indemnifying person to such indemnified person of its election to
         assume the defense thereof, such indemnifying person shall not be
         liable to such indemnified person for any legal expenses subsequently
         incurred by such indemnified person in connection with the defense
         thereof, provided, however, that if there exists or shall exist a
         conflict of interest that would make it inappropriate, in the opinion
         of counsel to the indemnified person, for the same counsel to represent
         both the indemnified person and such indemnifying person or any
         affiliate or associate thereof, the indemnified person shall be
         entitled to retain its own counsel at the expense of such indemnifying
         person; provided, however, that no indemnifying person shall be
         responsible for the fees and expenses of more than one separate counsel
         (together with appropriate local counsel) for all indemnified parties.
         In no event shall any indemnifying person be liable in respect of any
         amounts paid in settlement of any action unless the indemnifying person
         shall have approved the terms of such settlement; provided that such
         consent shall not be unreasonably withheld. No indemnifying person
         shall, without the prior written consent of the indemnified person,
         effect any settlement of any pending or threatened proceeding in
         respect of which any indemnified person is or could have been a party
         and indemnification could have been sought hereunder by such
         indemnified person, unless such settlement includes an unconditional
         release of such indemnified person from all liability on claims that
         are the subject matter of such proceeding.

                                    (v) If the indemnification provided for in
         this Section 4(d) is unavailable to or insufficient to hold harmless an
         indemnified party under Section 4(d)(1) or 4(d)(2) above in respect of
         any losses, claims, damages or liabilities (or actions or proceedings
         in respect thereof) referred to therein, then each indemnifying party
         shall contribute to the amount paid or payable by such indemnified
         party as a result of such losses, claims, damages or liabilities (or
         actions in respect thereof) in such proportion as is appropriate to
         reflect the relative fault of the Company on the one hand and Alonim as
         well as any other Selling Stockholders under such Registration
         Statement on the other in connection with the statements or omissions
         or other matters which resulted in such losses, claims, damages or
         liabilities (or actions in respect thereof), as well as any other
         relevant equitable considerations. The relative fault shall be
         determined by reference to, among other things, in the case of an
         untrue statement or omission, whether the untrue statement or omission
         relates to information supplied by the Company on the one hand or
         Alonim or other Selling Stockholder on the other and the parties'
         relative intent, knowledge, access to information and opportunity to
         correct or prevent such untrue statement or omission. The Company and
         Alonim agree that it would not be just and equitable if contribution

                                       11

         pursuant to this Section 4(d)(4) were determined by pro rata allocation
         (even if Alonim and other Selling Stockholders were treated as one
         entity for such purpose) or by any other method of allocation which
         does not take into account the equitable considerations referred to
         above in this Section 4(d)(4). The amount paid or payable by an
         indemnified party as a result of the losses, claims, damages or
         liabilities (or actions in respect thereof) referred to above in this
         Section 4(d)(4) shall be deemed to include any legal or other expenses
         reasonably incurred by such indemnified party in connection with
         investigating or defending any such action or claim. Notwithstanding
         the provisions of this Section 4(d)(4), Alonim and the other Selling
         Stockholders shall not be required to contribute any amount in excess
         of the amount by which the amount received by Alonim and other Selling
         Stockholders from the sale of the Registrable Shares to which such loss
         relates exceeds the amount of any damages which Alonim or such other
         Selling Stockholder has otherwise been required to pay by reason of
         such untrue statement or omission. No person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the
         Securities Act) shall be entitled to contribution from any person who
         was not guilty of such fraudulent misrepresentation.

                                    (vi) Each of Alonim and each of the
         Signatory Affiliates hereby acknowledges that it is a sophisticated
         business person who was represented by counsel during the negotiations
         regarding the provisions hereof including, without limitation, the
         provisions of this Section 4(d), and is fully informed regarding said
         provisions. Each of Alonim and each of its Affiliates further
         acknowledges that the provisions of this Section 4(d) fairly allocate
         the risks in light of the ability of Alonim and its Affiliates to
         investigate the Company and its business in order to assure that
         adequate disclosure is made in the Registration Statement as required
         by the Securities Act and the Exchange Act.

                           (e) Termination of Conditions and Obligations. The
         conditions precedent imposed by this Section 4 upon the transferability
         of the Registrable Shares shall cease and terminate as to any
         particular number of the Registrable Shares when such Registrable
         Shares shall have been effectively registered under the Securities Act
         and sold or otherwise disposed of in accordance with the intended
         method of disposition set forth in the Registration Statement covering
         such Registrable Shares or at such time as an opinion of counsel
         satisfactory to the Company shall have been rendered to the effect that
         such conditions are not necessary in order to comply with the
         Securities Act.

                           (f) Information Available. So long as the
         Registration Statement is effective covering the resale of Registrable
         Shares owned by Alonim, the Company will furnish to or otherwise make
         available to Alonim upon Alonim's request and at Alonim's expense:

                                    (i) a full copy of the Registration
         Statement; and

                                    (ii) an adequate number of copies of the
         prospectuses to supply to any other party requiring such prospectuses;
         and upon the reasonable request of Alonim, the Company will meet with
         Alonim or a representative thereof at the Company's headquarters to
         discuss all information relevant for disclosure in the Registration
         Statement covering the Registrable Shares and will otherwise cooperate
         with Alonim and its Affiliates for the purpose of reducing or
         eliminating such Alonim's exposure to liability under the Securities
         Act, including the reasonable production of information at the
         Company's headquarters; provided, that the Company shall not be
         required to disclose any confidential information to or meet at its
         headquarters with Alonim until and unless Alonim shall have entered
         into a confidentiality

                                       12

<PAGE>

         agreement in form and substance reasonably satisfactory to the Company
         with the Company with respect thereto.

                           (g) Effect on Prior Registration Rights. The
         registration rights granted by the Company in Section 5 of that certain
         Securities Purchase Agreement dated as of September 27, 2002 by and
         between the Company and S&F Financial is hereby superseded in its
         entirety and shall be of no further effect.

                           (h) "Market Stand-Off" Agreement. In connection with
         any underwritten offering of securities by the Company in which Alonim
         or its Affiliates participates, if requested by the managing
         underwriter of such offering, Alonim and its Affiliates shall agree to
         enter into a market stand-off agreement in customary form with such
         underwriter pursuant to which such holder will agree not to transfer or
         offer to transfer any Company securities (other than those included in
         the registration) during a period not to exceed ninety (90) days
         following the effective date of the Registration Statement with respect
         to such underwritten offering.

                  5.       Additional Agreements of the Parties.

                           (a) Alonim and the Company shall, as soon as
         practicable after the date hereof, amend the Amendment to provide that
         its current term be automatically extended by one year for each
         Reference Year (as such term is defined in the Note) which Alonim
         attains the applicable Target (as such term is defined in the Note),
         provided that neither Alonim nor any of its Affiliates shall, during
         the term of this Agreement and without the prior affirmative vote of a
         majority of the members of the Board of Directors of the Company,
         directly or indirectly, dispose, by sale or otherwise, of shares of
         Company Voting Stock or Derivative Securities such that the effect of
         such disposition would be to decrease by more than 50%, Alonim and its
         Affiliates' Peak Beneficial Ownership of such Company Voting Stock on a
         Fully Diluted Basis.

                           (b) During the term of this Agreement, the Company
         shall not take any action in such a manner that would cause Alonim and
         its Affiliates' aggregate Beneficial Ownership of Company Voting Stock
         on a Fully Diluted Basis to exceed the Standstill Percentage.

                  6.       Miscellaneous.

                           (a) Enforcement. The parties acknowledge and
         agree that irreparable damage would occur if any of the provisions of
         this Agreement were not performed in accordance with their specific
         terms or were otherwise breached. Accordingly, the parties will be
         entitled to an injunction or injunctions to prevent breaches of this
         Agreement and to enforce specifically its provisions in any court
         having jurisdiction, this being in addition to any other remedy to
         which they may be entitled at law or in equity.

                           (b) Aggregation. Any shares of Company Voting Stock
         transferred to or held by any Affiliates of Alonim will be aggregated
         together with shares held by Alonim for all purposes of this Agreement.
         All references made to Alonim in this Agreement shall be deemed to also
         constitute the agreement of the Affiliates of Alonim.

                           (c) Entire Agreement; Waivers. This Agreement, the
         Securities Purchase Agreement and the other agreements specifically
         contemplated by the Securities Purchase Agreement constitute the entire
         agreement among the parties hereto pertaining to the subject matter
         hereof and thereof and supersede all prior and contemporaneous
         agreements,

                                       13

<PAGE>

         understandings, negotiations and discussions, whether oral or written,
         of the parties with respect to such subject matter. No waiver of any
         provision of this Agreement shall be deemed or shall constitute a
         waiver of any other provision hereof or shall constitute a further or
         continuing waiver of that provision.

                           (d) Amendment or Modification. The parties hereto may
         not amend or modify this Agreement except in such manner as may be
         agreed upon by a written instrument executed by such parties.

                           (e) Successors and Assigns. All the terms and
         provisions of this Agreement shall be binding upon and shall inure to
         the benefit of the parties hereto and their respective successors, and
         each successor shall be deemed to be a party hereto for all purposes
         hereof. The terms and provisions of this Agreement shall not be binding
         upon any transferee (other than an Affiliate of Alonim) that purchases
         any securities subject to this Agreement without violation of any
         provision of this Agreement. Neither Alonim nor any of its Affiliates
         may assign or transfer any of its rights or obligations hereunder
         without the prior written consent of the Company, and no transfer or
         assignment by any party shall relieve such party of any of its
         obligations hereunder.

                           (f) Severability. If any provision of this Agreement
         is held by a court of competent jurisdiction to be unenforceable, the
         remaining provisions shall remain in full force and effect. It is
         declared to be the intention of the parties that they would have
         executed the remaining provisions without including any that may be
         declared unenforceable.

                           (g) Headings. Descriptive headings are for
         convenience only and will not control or affect the meaning or
         construction of any provision of this Agreement.

                           (h) Counterparts. For the convenience of the parties,
         any number of counterparts of this Agreement may be executed by the
         parties, and each such executed counterpart will be an original
         instrument.

         or other communications hereunder shall be in writing and shall be

                                    APPENDIX

    DETERMINING "BENEFICIAL OWNERSHIP"

         (a)      A "Beneficial Owner" of a security includes any person who,
                  directly or indirectly, through any contract, arrangement,
                  understanding, relationship or otherwise has or shares:

                  (1)      Voting power which includes the power to vote, or
                           to direct the voting of, such security; and/or

                  (2)      Investment power which includes the power to
                           dispose, or direct the disposition of, such
                           security.

                  Please note that either voting power or investment power, or
                  both, is sufficient for you to be considered the beneficial
                  owner of shares.

         (b)      Any person who, directly or indirectly, creates or uses a
                  trust, proxy, power of attorney, pooling arrangement or any
                  other contract, arrangement or device with the purpose or
                  effect of divesting such person of beneficial ownership of a
                  security or preventing the vesting of such beneficial
                  ownership as part of a plan or scheme to evade the reporting
                  requirements of the federal securities acts shall be deemed to
                  be the beneficial owner of such security.

         (c)      Notwithstanding  the provisions of paragraph (a), a person is
                  deemed to be the "beneficial owner" of a security, if that
                  person has the right to acquire beneficial ownership of such
                  security within 60 days, including but not limited to any
                  right to acquire: (A) through the exercise of any option,
                  warrant or right; (B) through the conversion of a security;
                  (C) pursuant to the power to revoke a trust, discretionary
                  account or similar arrangement; or (D) pursuant to the
                  automatic termination of a trust, discretionary account or
                  similar arrangement; provided, however, any person who
                  acquires a security or power specified in paragraphs (A), (B)
                  or (C) above, with the purpose or effect of changing or
                  influencing the control of the issuer, or in connection with
                  or as a participant in any transaction having such purpose or
                  effect, immediately upon such acquisition shall be deemed to
                  be the beneficial owner of the securities which may be
                  acquired through the exercise or conversion of such security
                  or power.
