     AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the "Agreement") made as of
     September 7, 2001, by and between NetSilicon, Inc., a Massachusetts
     corporation (the "Company"), and Daniel J. Sullivan (the "Executive").

--------------------------------------------------------------------------------

     WHEREAS, the Company and Executive entered into an Employment Agreement
dated as of August 9, 2001 (the "Original Employment Agreement"), and the
Company and Executive desire to amend certain provisions of the Original
Employment Agreement; and

     WHEREAS, the Company wishes to secure the future services of the Executive
with the Company pursuant to the terms of this Agreement.

     NOW, THEREFORE, the parties agree as follows:

1)   TERM.

     a)   The Company hereby agrees to continue to employ the Executive and the
          Executive hereby agrees to continue employment with the Company, in
          the position set forth in Section 2 below, for the Term (as defined
          below), subject to the terms and conditions of this Agreement.

     b)   The term (the "Term") of this Agreement shall commence as of the date
          of the Original Employment Agreement (the "Effective Date") and shall
          continue until terminated in accordance with Section 4.

2)   POSITION, DUTIES AND RESPONSIBILITIES.

     a)   During the Term, the Executive shall be employed by the Company and
          shall serve the Company as its Executive Vice President of Finance and
          Operations and Chief Financial Officer (the "CFO"). The Executive
          shall have such duties and responsibilities as are incident to, or
          reasonably requested in connection with, such position, as well as
          such other comparable duties and responsibilities as may be assigned
          to him by the Company. The Executive shall report to the Chief
          Executive Officer (the "CEO") or to such comparable or higher level of
          authority and responsibility within the Company as the CEO or the
          Board of Directors (the "BOD") may reasonably determine.

     b)   During the Term, the Executive shall serve the Company faithfully,
          diligently and to the best of the Executive's ability, and shall
          devote substantially all of the Executive's business time and efforts
          to such service. The Executive also shall not engage in any other
          business activity without the written consent of the Company, except
          that Executive may (i) carry on charitable, civic, or other
          non-for-profit activities or (ii) manage his personal investments,
          provided that none of such activities may conflict with the
          Executive's duties under this Agreement and the Non-Disclosure,
          Proprietary Rights and Non-Solicitation Agreement dated as of March
          10, 2000 (the "Nondisclosure

                                      -2-


          Agreement"). If the Executive shall be elected to other offices of the
          Company or any of its affiliates, he shall serve in such positions
          without further compensation than provided for in this Agreement. The
          Executive shall perform his services under this Agreement at such
          locations as may be required by the Company from time to time, but the
          Company will not require the Executive to permanently relocate to an
          office more than 50 miles from the Company's Waltham, Massachusetts
          office.

     c)   The Executive agrees to comply with the policies and procedures of the
          Company applicable to its U.S. employees generally from time to time
          that are in force (which may be amended, revised or supplemented at
          any time in the Company's sole discretion), provided, however, that to
          the extent there is a conflict between the terms of this Agreement and
          the policies and procedures of the Company, the terms of this
          Agreement shall govern unless otherwise specified herein.

3)   COMPENSATION AND BENEFITS. During the term of this Agreement, the Company
     shall pay the Executive as compensation for his satisfactory performance of
     his duties and obligations hereunder, the following:

     a)   BASE SALARY. During the Term, the Company shall pay to the Executive a
          base salary at the rate of U.S. $12,500.00 per month ("Base Salary"),
          subject to annual change in the discretion of the Company in
          accordance with the Company's executive compensation practices, and
          payable in accordance with the regular payroll practices of the
          Company as may be modified or established from time to time.

     b)   INCENTIVE COMPENSATION. During the Term, the Executive shall be
          eligible to receive additional quarterly incentive compensation (the
          "Incentive Bonus"). The amount of the Incentive Bonus, if any, will be
          as determined by the BOD's Compensation Committee (which may put in
          place an Executive Incentive Plan), which may consider, among other
          things, the Executive's actual attainment of specific goals and the
          Company's overall performance. The BOD's Compensation Committee will
          make all determinations regarding the Executive's eligibility for the
          quarterly Incentive Bonus at its sole discretion. Subject to the
          provisions of Section 4 herein, the Executive must be employed by the
          Company in good standing (as determined by the BOD) as the Company's
          CFO to be eligible for any Incentive Bonus payments, which will be
          subject to applicable taxes and payable in accordance with the
          Company's normal bonus pay practices as may be established or modified
          from time to time.

     c)   STOCK OPTIONS. The Executive has received certain stock options as
          part of the Company's initial public offering as well as additional
          awards thereafter in accordance with Company option policy. The
          Executive shall be eligible to receive additional stock option awards
          as determined by the BOD in its sole discretion.

     d)   BENEFITS. Subject to any contribution therefor generally required of
          senior executives of the Company, the Executive shall be eligible to
          participate in all employee benefits plans, including the Company's
          health and dental plans, as adopted by the BOD and in effect for
          senior executives of the Company. Such participation shall be subject
          to (i) the terms of

<PAGE>   3
                                      -3-


          the applicable plan documents, (ii) generally applicable Company
          policies and (iii) the discretion of the BOD or any administrative or
          other committee provided for in or contemplated by such plans.

     e)   EXPENSES. The Company shall pay or reimburse the Executive for all
          reasonable business expenses incurred or paid by the Executive in the
          performance of his responsibilities hereunder in accordance with the
          Company's prevailing policy and practice relating to reimbursements as
          established, modified or amended from time to time. The Executive must
          provide substantiation and documentation of these expenses to the
          Company in order to receive reimbursement, as required pursuant to
          Company policy.

     f)   CHANGE OF CONTROL. In the event of a Change of Control that occurs on
          or before January 1, 2002, or in the event that the Company and a
          third party have executed a binding agreement on or before such date
          to consummate a Change of Control and such Change of Control occurs
          within the three month period following January 1, 2002, where in each
          case the Company is or will be sold to a party that is unaffiliated
          with Sorrento Networks, Inc., or its successors and assigns
          ("Sorrento") and the Executive substantially contributes, as
          determined in good faith at the sole discretion of the BOD, to the
          success of the transaction, the Executive shall be entitled to receive
          one quarter (.25) of one percent of the Consideration (as hereinafter
          defined). Such fee shall be paid in the same form and at such time as
          the Company, or its stockholders, as the case may be, receives its
          Consideration pursuant to such transaction. In addition, after the
          consummation of a Change of Control which occurs at any time, the
          Executive's unvested stock options will vest immediately and become
          exercisable for a period of twenty-four (24) months from the date of
          the consummation of a Change of Control. "Consideration" shall mean
          the aggregate value, whether in cash or securities, paid to the
          shareholders of the Company in their capacity as such in respect of
          the shares of common stock of the Company held by them in connection
          with a Change of Control. The value of any Consideration and the
          payment to the Executive shall be determined in good faith by the BOD.

4)   TERMINATION OF EMPLOYMENT.

     a)   TERMINATION BY THE COMPANY FOR CAUSE. In the event that the Company
          terminates the Executive's employment and this Agreement for Cause (as
          defined in Section 5(a)), the Executive shall be entitled to no
          payments, salary continuation, severance or other benefits, except
          for: (i) Base Salary earned and accrued but unpaid through the date of
          Executive's termination of employment; (ii) payment for accrued but

          payments and subject to applicable law and the requirements of the
          Company's health insurance plans then in effect; and (iv) all expenses
          reimbursable to the Executive and unpaid as of the date of Executive's

          the Executive, or the Executive's legal representative, shall be

          after the Executive's death or Disability; (ii) payment for accrued
          but unused vacation time up to the Executive's termination of
          employment; (iii) statutory benefit continuation rights in accordance
          with COBRA, provided Executive makes the appropriate voluntary

          requirements of the Company's health insurance plans then in effect;
          (iv) the Executive's unvested stock options shall vest as if the
          vesting start date with respect to such stock options were one year
          prior to the vesting start date set forth in the applicable option
          agreements and become exercisable for a period of ninety (90) days

          Cause, the Executive shall be entitled to no payments, salary
          continuation, severance or other benefits, except for: (i) severance
          payment in the form of continuation of his Base Salary for twelve (12)
          months at the same rate in effect as of the Executive's last day of
          employment with the Company, payable pursuant to the regular payroll
          practices of the Company over such twelve (12) month period; (ii)
          payment for accrued but unused vacation time up to the Executive's
          termination of employment; (iii) if the Executive elects after the

          health coverage under the same plans available to active Company
          employees, under the same rules, restrictions and regulations
          applicable thereto, the Company shall make premium payments on his
          behalf until the earlier of (x) twelve (12) months from the last day
          of the Executive's employment or (y) the date on which the Executive
          becomes ineligible to receive COBRA benefits; and (iv) all expenses
          reimbursable to the Executive and unpaid as of the date of Executive's
          termination of employment. In addition, in the event the Executive's

          Executive's unvested stock options will vest immediately and become
          exercisable for a period of twenty-four (2) months from the date of
          the Executive's termination without Cause. The Executive shall be
          entitled to no other benefits or additional payments under this
          Agreement.

     d)   VOLUNTARY TERMINATION. The Executive may voluntarily terminate his
          employment (thereby effectuating a "Voluntary Termination") only upon
          sixty (60) days' written notice to the BOD. In the event of a
          Voluntary Termination, the Company may accelerate Executive's
          departure date (and terminate this Agreement) and will have no
          obligation to pay Executive after his actual departure date. In the
          event of a Voluntary Termination, and if no proceedings to terminate
          the Executive for Cause have been initiated, the Executive shall be
          entitled to no payments, salary continuation, severance or other
          benefits, except for those payments and benefits as set forth in
          Section 4(a).

     e)   TERMINATION BY THE EXECUTIVE FOR GOOD REASON. In the event the
          Executive decides to terminate this Agreement and his employment for
          Good Reason (as defined in Section 5(e)), then the Executive must give
          notice of such termination to the Company and the BOD. If the basis
          for such Good Reason is not cured within thirty (30) days after the
          Company and the BOD receive written notice specifying the basis of
          such Good Reason (as determined by the BOD in good faith), this
          Agreement, and the Executive's employment, shall terminate. In the
          event of a termination by the Executive for Good Reason, the Executive
          shall be entitled to the severance payments as set forth in Section
          4(c).

          severance payments and benefits outlined in Section 4(b), 4(c), 4(d)
          or 4(e), as the case may be, the Executive must execute a
          comprehensive release of all claims in favor of the Company and its
          officers, directors, employees, shareholders, agents and/or
          representatives.

     g)   CESSATION OF SEVERANCE PAYMENTS AND BENEFITS. If the Executive
          breaches in any material respect his obligations under this Agreement
          or the Nondisclosure Agreement, the Company may immediately cease
          payment of all severance and/or benefits described in this Agreement.
          This cessation of severance and/or benefits shall be in addition to,
          and not as an alternative to, any other remedies in law or in equity
          available to the Company, including the right to seek specific
          performance or an injunction.

Agreement. In addition, the remaining provisions of this Agreement or such other
agreements shall be unaffected thereby and shall be construed, reformed and thus
remain in full force and effect to the fullest extent permitted by law.
