                               SEVERANCE AGREEMENT
                               -------------------

This Severance Agreement (the "Agreement") is effective as of February 19, 1999,
by and between David A. Everett (the "Executive") and Phoenix Technologies Ltd.,
a Delaware corporation (the "Company").

                                    RECITALS

A.   Management of the Company believes that it is in the best interest of
     the Company and its stockholders to provide the Executive with certain
     severance benefits should Executive's employment with the Company
     terminate under certain circumstances. Such benefits will provide
     Executive with enhanced financial security and with sufficient
     incentive and encouragement for Executive to remain with the Company.

B.   To accomplish the foregoing objectives, the Company will, upon
     execution of this Agreement by the parties, agree to the terms
     provided herein.

C.   Certain capitalized terms used in the Agreement are defined in Section
     7 below.

                                    AGREEMENT

     In consideration of the mutual covenants herein contained, and in
consideration of the continuing employment of Executive by the Company, the
parties agree as follows:

     1.   Duties and Scope of Employment. The Company currently employs
          ------------------------------
          Executive as Senior Vice President. The Executive shall comply with
          and be bound by the Company's operating policies, procedures and
          practices from time to time in effect during his employment. Executive
          shall continue to devote his full time, skill and attention to her
          duties and responsibilities, and shall perform them faithfully,
          diligently and competently, and the Executive shall use his best
          efforts to further the business of the Company and its affiliated
          entities.

     2.   Base Compensation. The Company shall continue to pay Executive as
          -----------------
          compensation for his services a base salary in accordance with normal
          Company payroll practices ("Base Compensation"). The Base Compensation
          may be increased from time to time, in which case the "Base
          Compensation" will refer to the base salary earned by Executive at the
          time in question.

     3.   Executive Benefits. The Executive shall be eligible to participate in
          ------------------
          the employee benefit plans and executive compensation programs
          maintained by the Company applicable to other key executives of the
          Company, including (without limitation) retirement plans, savings or
          profit-sharing plans, stock options, incentive or other bonus plans,
          life, disability, health, accident and other insurance programs, paid
          vacations, and similar plans or programs, subject in each case to the
          generally applicable terms and conditions of the applicable plan or
          program in question and to the sole determination of the Board or any
          committee administering such plan or program.

<PAGE>

     (a)  Stock Option Grants. Executive will receive an annual grant of stock
          -------------------
          options during the term of this Agreement in a manner and under terms
          that are consistent with grants made to other executives of the
          Company.

     (b)  Bonus Eligibility and Payment. Executive is currently eligible to
          -----------------------------
          receive a bonus based on application of the terms of the executive
          bonus plan (i.e. if the Company fails to meet minimum financial
          objectives or Executive fails to complete personal objectives under
          the plan, no bonus will be paid). Such bonus, if any, will be paid to
          Executive at approximately the same time other Company Executives
          receive their bonuses.

4.   Term of Agreement. The terms of this Agreement shall terminate on the date
     -----------------
     that all obligations of the parties hereunder have been satisfied. A
     termination of the terms of this Agreement pursuant to this Section shall
     be effective for all purposes.

5.   Severance Benefits.
     ------------------

     (a)  Termination Not for Cause. If the Company terminates Executive's
          -------------------------
          employment for any reason other than Cause, or terminates Executive by
          Constructive Termination as defined in this Agreement, the Executive
          shall be entitled to receive the following severance benefits:

          (i)  Severance Payments.
               ------------------

               (1)  Guaranteed Severance Payments. Subject to Executive entering
                    -----------------------------
                    into a Release of Claims (in a form substantially similar to
                    the release of claims attached as Exhibit A), Executive
                    shall be entitled to receive severance payments for twelve
                    (12) months from the date of termination at Executive's then
                    current base salary, which may be greater than, but will not
                    be less than the Base Compensation (the "Guaranteed
                    Severance Payment"). The Guaranteed Severance Payment will
                    be paid to Executive in accordance with the Company's
                    standard payroll practices. Upon termination, Executive will
                    also be entitled to receive a pro rate portion of his then
                    current targeted bonus for the fiscal year following his
                    termination as described in Section 3(b)(ii).

               (2)  Contingent Severance Payments. If Executive has not secured
                    -----------------------------
                    Reemployment as of the end of the twelve (12) month period,
                    Executive shall be eligible to receive an additional six (6)
                    months of Base Compensation, also paid in accordance with
                    the Company's standard payroll practices ("Contingent
                    Severance Payments"). The Contingent Severance Payments
                    shall discontinue upon Executive notifying Company of
                    Re-Employment.

     (ii) Medical Benefits. The Company, at the Company's sole expense, shall
          ----------------
          provide Executive (and, if applicable, his eligible depdents) with the
          same level of health coverage and benefits as in effect for Executive
          (and, if applicable, his eligible dependents) on the day immediately
          preceding the day of the Executive's termination of employment (the
          "Company-Paid Coverage"); provided, however, that (i) Executive and
          each eligible dependent constitutes a qualified beneficiary, as
          defined in Section 4980B(g)(1) of the Internal Revenue Code of 1986,
          as amended (collectively, "Qualified Beneficiaries"); (ii) each
          Qualified Beneficiary elects continuation coverage under the
          Consolidated Omnibus Budget Reconciliation Act of 1985, as amended
          ("COBRA"), within the time period prescribed pursuant to COBRA; and
          (iii) if the health coverage is no longer offered by the Company to
          its current employees, then the Company shall be under no obligation
          to continue the existing coverage for Executive (and, if applicable,
          his eligible dependents). Such Company-Paid Coverage shall continue in
          effect for each Qualified Beneficiary until the earlier of (i) the
          Qualified Beneficiary is no longer eligible to receive continuation
          coverage under COBRA, or (ii) eighteen (18) months following
          termination of employment pursuant to Section 5(a).

    (iii) Change in Control. In the event the Company undergoes a Change in
          -----------------
          Control, or other material event in that the Company or Key
          Executive's position undergoes a material change as a result of the
          material event, Key Executive's stock options will accelerate vesting
          such that fifty percent (50%) of the options will vest at the
          completion of the Change in Control, or material event, and the
          remaining fifty percent (50%) will vest 90 days thereafter. If there
          is an inconsistency between this Agreement and the Company's Stock
          Option Plan or a Stock Option Agreement, the terms of this Agreement
          shall prevail.

(b)  Voluntary Resignation; Termination For Cause. If the Executive voluntarily
     --------------------------------------------
     resigns from the Company, or if the Company terminates the Executive's
     employment for Cause, then the Executive shall not be entitled to receive
     severance or other benefits pursuant to this Agreement. However, Executive
     shall remain eligible for the severance and other benefits (if any) as may
     then be available under the Company's then existing severance and benefits
     plans and policies at the time of Executive's termination.

(c)  Disability; Death. If the Company terminates the Executive's employment as
     -----------------
     a result of the Executive's Disability or if the Executive's employment
     terminates due to the death of the Executive, then the Executive shall not
     be entitled to receive severance or other benefits pursuant to this
     Agreement. However, Executive shall remain eligible for those severance and
     other benefits (if any) as may be available under the Company's then
     existing severance and benefit plans and policies at the time of
     Executive's termination or death.

6.   Covenants Not to Compete and Not to Solicit.
     -------------------------------------------

     (a)  Upon the termination of the Executive's employment with the Company
          pursuant to Section 5(a) and for a period of eighteen (18) months
          thereafter, Executive agrees that he shall not, on his own behalf, or
          as owner, manager, advisor, principal, agent, partner, consultant,
          director, officer, stockholder, or employee of any business entity, or
          otherwise in any territory in which the Company is actively engaged in
          business (i) open or operate any business which is in competition with
          any business of the Company, (ii) act as an employee, agent, advisor
          or consultant or any competitor of the Company, (iii) solicit or
          accept business from any of the Company's competitors, (iv) take any
          action to or do anything reasonably intended to divert business from
          the Company or influence or attempt to influence any existing
          customers of the Company to cease doing business with the Company or
          to alter its business relationship with the Company, or (v) take any
          action or do anything reasonably intended to influence any suppliers
          of the Company to cease doing business with the Company or to alter
          its business relationship with the Company. Executive further
          covenants and agrees that he will not for himself or on behalf of any
          other person, partnership, firm, association or corporation in any
          territory served by the Company, directly or indirectly solicit or
          accept business from any of the Company's existing customers for the
          purchase or sale of products or services of a like kind to those sold
          or provided the Company. The foregoing covenant shall not be deemed to
          prohibit Executive from acquiring an investment not more than one
          percent (1%) of the capital stock of a competing business, whose stock
          is traded on a national securities exchange or through the automated
          quotation system of a registered securities association.

     (b)  Upon the termination of the Executive's employment with the Company
          pursuant to Section 5(a) and for a period of eighteen (18) months
          thereafter, Executive agrees that he shall not either directly or
          indirectly solicit, induce, attempt to hire, recruit, encourage, take
          away, hire any employee of the Company or cause any employee of the
          Company to leave his or her employment either for Executive or for any
          other entity or person.

     (c)  Executive represents that he (i) is familiar with the foregoing
          covenants not to compete and not to solicit, and (ii) is fully aware
          of his obligations hereunder, including, without limitation, the
          reasonableness of the length of time, scope and geographic coverage of
          these covenants.

     (d)  Company will respond within two weeks to any written request by
          Executive to exclude a particular company or business entity from the
          scope of this Section 6. Company will not unreasonably deny such a
          request. The parties agree that a passive financial investment by
          Executive in a third party will not constitute competition within the
          scope of this Section 6.

     Agreement shall have the following meanings for the purposes of this

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

                     (B)  A corporation owned directly or indirectly by the
                          stockholders of the Company in substantially the same

In consideration for Executive accepting the benefits under his Severance
Agreement dated January 4, 2001, Executive agrees to release Company of all
claims arising from his employment as set forth below.

Employee hereby forever waives for himself, his attorneys, heirs, executors,
administrators, successors and assigns any claims against Phoenix, including its
subsidiaries, affiliates, insurers, shareholders, officers, directors and
employees (the "Parties Released"), for any action, loss, expense or any damages
arising from any occurrence from the beginning of time until the date of the
signing of this Agreement and arising or in any way resulting from Employee's
employment with Phoenix or the termination thereof. The only exceptions to the
above waiver are claims by Employee under any worker's compensation or
unemployment statutes and any right arising under this Agreement. Employee
represents that he has no current intention to assert any claim on any basis
against the Parties Released. Phoenix releases its claims on intellectual
property created by Employee after the date of execution of this Agreement.

for such breach shall be limited to the enforcement of the terms of this
Agreement.
