                              INDEMNITY AGREEMENT

          THIS AGREEMENT is made and entered into this ____ day of _____, 2001
and effective as of April 12, 2001, by and between Openwave Systems Inc., a
Delaware corporation and its subsidiaries (collectively, the "Corporation"), and
_________________ ("Agent").

                                    RECITALS

          WHEREAS, Agent performs a valuable service to the Corporation in
his/her capacity as a director, officer or other fiduciary of an affiliate of
the Corporation;

          WHEREAS, the current By-laws and Amended and Restated Certificate of
Incorporation (collectively, the "Charter Documents") require the Corporation to
indemnify and advance expenses to its directors and officers to the full extent
permitted by the Delaware General Corporation Law, as amended (as applicable,
the "Code") and the Agent intends to continue serving as a director or officer
of the Corporation in part in reliance on such Charter Documents and Code;

          WHEREAS, the Charter Documents and the Code, by their non-exclusive
nature, permit contracts between the Corporation and its agents, officers,
employees and other agents with respect to indemnification of such persons; and

          WHEREAS, in order to induce Agent to continue to serve the
Corporation, the Corporation has determined and agreed to enter into this
Agreement with Agent;

          NOW, THEREFORE, in consideration of Agent's continued service to the
Corporation, the parties hereto agree as follows:

                                   AGREEMENT

          1.  SERVICES TO THE CORPORATION.  Agent will serve, at the will of the
Corporation or under separate contract, if any such contract exists, as a
director, officer or other fiduciary of an affiliate of the Corporation
(including any employee benefit plan of the Corporation) faithfully and to the
best of his ability so long as he is duly elected and qualified in accordance
with the provisions of the Charter Documents or the charter documents of such
affiliate; provided, however, that Agent may at any time and for any reason
resign from such position (subject to any contractual obligation that Agent may
have assumed apart from this Agreement) and that the Corporation or any
affiliate shall have no obligation under this Agreement to continue Agent in any
such position.

          2.  INDEMNITY OF AGENT.

          (a) The Corporation hereby agrees to hold harmless and indemnify Agent
          to the fullest extent authorized or permitted by the provisions of the
          Charter Documents and the Code, as the same may be amended from time
          to time (but, only to the extent that such amendment permits the
          Corporation to provide broader indemnification rights than the Charter
          Documents or the Code permitted prior to adoption of such amendment).

          (b) Notwithstanding the foregoing, (i) the obligations of the
          Corporation under Section 2(a) shall be subject to the condition that
          the Reviewing Party (as defined below) shall not have determined (in a
          written opinion, in any case in which the Independent Legal Counsel
          referred to in Section 11(a) hereof is involved) that Agent would not
          be permitted to be indemnified under applicable law, and (ii) the
          obligation of the Corporation to make an advance pursuant to Section 8
          shall be subject to the condition that, if, when and to the extent
          that the Reviewing Party determines that Agent would not be permitted
          to be so indemnified under applicable law, the Corporation shall be
          entitled to be reimbursed by Agent (who hereby agrees to reimburse the
          Corporation) for all such amounts theretofore paid; provided, however,
          that if Agent has commenced or thereafter commences legal proceedings
          in a court of competent jurisdiction to secure a determination that
          Agent should be indemnified under applicable law, any determination
          made by the Reviewing Party that Agent would not be permitted to be
          indemnified under applicable law shall not be binding and Agent shall
          not be required to reimburse the Corporation for any advance until a
          final judicial determination is made with respect thereto (as to which
          all rights of appeal therefrom have been exhausted or lapsed).  If
          there has not been a Change in Control (as defined below), the
          Reviewing Party shall be selected by the Board of Directors, and if
          there has been such a Change in Control (other than a Change in
          Control which has been approved by a majority of the Corporation's
          Board of Directors who were directors immediately prior to such Change
          in Control), the Reviewing Party shall be the Independent Legal
          Counsel referred to in Section 11(a) hereof.  If there has been no
          determination by the Reviewing Party or if the Reviewing Party
          determines that Agent substantively would not be permitted to be
          indemnified in whole or in part under applicable law, Agent shall have
          the right to commence litigation in any court in the State of Delaware
          having subject matter jurisdiction thereof and in which venue is
          proper seeking an initial determination by the court or challenging
          any such determination by the Reviewing Party or any aspect thereof,
          including the legal or factual bases therefor, and the Corporation
          hereby consents to service of process and to appear in any such
          proceeding.  Any determination by the Reviewing Party otherwise shall
          be conclusive and binding on the Corporation and Agent.

                                       2
<PAGE>

          "Reviewing Party" shall mean any appropriate person or body consisting
          of a member or members of the Corporation's Board of Directors or any
          other person or body appointed by the Board who is not a party to the
          particular claim for which Agent is seeking indemnification, or
          Independent Legal Counsel.

          3.  ADDITIONAL INDEMNITY.  In addition to and not in limitation of the
indemnification otherwise provided for herein, and subject only to the
exclusions set forth in Sections 4 and 7 hereof, the Corporation hereby further
agrees to hold harmless and indemnify Agent:

          (a) against any and all expenses (including attorneys' fees), witness
          fees, damages, judgments, fines and amounts paid in settlement and any
          other amounts that Agent becomes legally obligated to pay because of
          any claim or claims made against or by him in connection with any
          threatened, pending or completed action, suit or proceeding, whether
          civil, criminal, arbitrational, administrative or investigative
          (including an action by or in the right of the Corporation) to which
          Agent is, was or at any time becomes a party, or is threatened to be
          made a party, by reason of the fact that Agent is, was or at any time
          becomes a director, officer, employee or other agent of Corporation,
          or is or was serving or at any time serves at the request of the
          Corporation as a director, officer, employee or other agent of another
          corporation, partnership, joint venture, trust, employee benefit plan
          or other enterprise; and

          (b) otherwise to the fullest extent as may be provided to Agent by the
          Corporation under the non-exclusivity provisions of the Code and the
          Charter Documents.

          4.  LIMITATIONS ON ADDITIONAL INDEMNITY.  No indemnity pursuant to
Section 3 hereof shall be paid by the Corporation:

          (a) on account of any claim against Agent for an accounting of profits
          made from the purchase or sale by Agent of securities of the
          Corporation pursuant to the provisions of Section 16(b) of the
          Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
          amendments thereto or similar provisions of any federal, state or
          local statutory law;

          (b) on account of Agent's conduct that was knowingly fraudulent or
          deliberately dishonest or that constituted willful misconduct;

          (c) on account of Agent's conduct that constituted a breach of Agent's
          duty of loyalty to the Corporation or resulted in any personal profit
          or advantage to which Agent was not legally entitled;

                                       3
<PAGE>

          (d) for which payment is actually made to Agent under a valid and
          collectible insurance policy or under a valid and enforceable
          indemnity clause, bylaw or agreement, except in respect of any excess
          beyond payment under such insurance, clause, bylaw or agreement;

          (e) if indemnification is not lawful (and, in this respect, both the
          Corporation and Agent have been advised that the Securities and
          Exchange Commission believes that indemnification for liabilities
          arising under the federal securities laws is against public policy and
          is, therefore, unenforceable and that claims for indemnification
          should be submitted to appropriate courts for adjudication); or

          (f) in connection with any proceeding (or part thereof) initiated by
          Agent, or any proceeding by Agent against the Corporation or its
          directors, officers, employees or other agents, unless (i) such
          indemnification is expressly required to be made by law, (ii) the
          proceeding was authorized by the Board of Directors of the
          Corporation, (iii) such indemnification is provided by the
          Corporation, in its sole discretion, pursuant to the powers vested in
          the Corporation under the Code, or (iv) the proceeding is initiated
          pursuant to Section 9 hereof.

          5.  CONTINUATION OF INDEMNITY.  All agreements and obligations of the
Corporation contained herein shall continue during the period Agent is a
director, officer, employee or other agent of the Corporation (or is or was
serving at the request of the Corporation as a director, officer, employee or
other agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise) and shall continue thereafter so long as Agent
shall be subject to any possible claim or threatened, pending or completed
action, suit or proceeding, whether civil, criminal, arbitrational,
administrative or investigative, by reason of the fact that Agent was serving in
the capacity referred to herein.

          6.  PARTIAL INDEMNIFICATION.  Agent shall be entitled under this
Agreement to indemnification by the Corporation for a portion of the expenses
(including attorneys' fees), witness fees, damages, judgments, fines and amounts
paid in settlement and any other amounts that Agent becomes legally obligated to
pay in connection with any action, suit or proceeding referred to in Section 3
hereof even if not entitled hereunder to indemnification for the total amount
thereof, and the Corporation shall indemnify Agent for the portion thereof to
which Agent is entitled.

          7.  NOTIFICATION AND DEFENSE OF CLAIM.  Not later than thirty (30)
days after receipt by Agent of notice of the commencement of any action, suit or
proceeding, Agent will, if a claim in respect thereof is to be made against the
Corporation under this Agreement, notify the Corporation of the commencement
thereof; but the omission so to notify the Corporation will not relieve it from
any liability which it may

                                       4
<PAGE>

have to Agent otherwise than under this Agreement. With respect to any such
action, suit or proceeding as to which Agent notifies the Corporation of the
commencement thereof:

          (a) the Corporation will be entitled to participate therein at its own
          expense;

          (b) except as otherwise provided below, the Corporation may, at its
          option and jointly with any other indemnifying party similarly
          notified and electing to assume such defense, assume the defense
          thereof, with counsel reasonably satisfactory to Agent.  After notice
          from the Corporation to Agent of its election to assume the defense
          thereof, the Corporation will not be liable to Agent under this
          Agreement for any legal or other expenses subsequently incurred by
          Agent in connection with the defense thereof except for reasonable
          costs of investigation or otherwise as provided below. Agent shall
          have the right to employ separate counsel in such action, suit or
          proceeding but the fees and expenses of such counsel incurred after
          notice from the Corporation of its assumption of the defense thereof
          shall be at the expense of Agent unless (i) the employment of counsel
          by Agent has been authorized by the Corporation, (ii) Agent shall have
          reasonably concluded that there may be a conflict of interest between
          the Corporation and Agent in the conduct of the defense of such action
          or (iii) the Corporation shall not in fact have employed counsel to
          assume the defense of such action, in each of which cases the fees and
          expenses of Agent's separate counsel shall be at the expense of the
          Corporation. The Corporation shall not be entitled to assume the
          defense of any action, suit or proceeding brought by or on behalf of
          the Corporation or as to which Agent shall have made the conclusion
          provided for in clause (ii) above; and

          (c) the Corporation shall not be liable to indemnify Agent under this
          Agreement for any amounts paid in settlement of any action or claim
          effected without its written consent, which shall not be unreasonably
          withheld.  The Corporation shall be permitted to settle any action
          except that it shall not settle any action or claim in any manner
          which would impose any penalty or limitation on Agent without Agent's
          written consent, which may be given or withheld in Agent's sole
          discretion.

          8.  EXPENSES.  The Corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by Agent in connection with such proceeding upon receipt of an
undertaking by or on behalf of Agent to repay said amounts if it shall be
determined ultimately that Agent is not entitled to be indemnified under the
provisions of this Agreement, the Charter Documents, the Code or otherwise.

          9.  ENFORCEMENT.  Any right to indemnification or advances granted by
this Agreement to Agent shall be enforceable by or on behalf of Agent in any
court of competent jurisdiction if (i) the claim for indemnification or advances
is denied, in

                                       5
<PAGE>

whole or in part, or (ii) no disposition of such claim is made within twenty
(20) days of request therefor. Agent, in such enforcement action, if successful
in whole or in part, shall be entitled to be paid also the expense of
prosecuting his claim. It shall be a defense to any action for which a claim for
indemnification is made under Section 3 hereof (other than an action brought to
enforce a claim for expenses pursuant to Section 8 hereof, provided that the
required undertaking has been tendered to the Corporation) that Agent is not
entitled to indemnification because of the limitations set forth in Section 4
hereof. Neither the failure of the Corporation (including its Board of Directors
or its shareholders) to have made a determination prior to the commencement of
such enforcement action that indemnification of Agent is proper in the
circumstances, nor an actual determination by the Corporation (including its
Board of Directors or its shareholders) that such indemnification is improper
shall be a defense to the action or create a presumption that Agent is not
entitled to indemnification under this Agreement or otherwise.

          10.  SUBROGATION.  In the event of payment under this Agreement, the
Corporation shall be surrogated to the extent of such payment to all of the
rights of recovery of Agent, who shall execute all documents required and shall
do all acts that may be necessary to secure such rights and to enable the
Corporation effectively to bring suit to enforce such rights.

          11.  CHANGE IN CONTROL AND ESTABLISHMENT OF TRUST.

          (a) The Corporation agrees that if there is a Change in Control (as
          defined below) of the Corporation (other than a Change in Control
          which has been approved by a majority of the Corporation's Board of
          Directors who were directors immediately prior to such Change in
          Control) then with respect to all matters thereafter arising
          concerning the rights of Agent to indemnity payments and advances
          under this Agreement or any other agreement or Corporation By-law now
          or hereafter in effect relating to claims, the Corporation shall seek
          legal advice only from Independent Legal Counsel (as defined below)
          selected by Agent and approved by the Corporation (which approval
          shall not be unreasonably withheld).  Such counsel, among other
          things, shall render its written opinion to the Corporation and Agent
          as to whether and to what extent the Agent would be permitted to be
          indemnified under applicable law.  The Corporation agrees to pay the
          reasonable fees of the Independent Legal Counsel referred to above and
          to indemnify fully such counsel against any and all expenses
          (including attorneys' fees), claims, liabilities and damages arising
          out of or relating to this Agreement or its engagement pursuant
          hereto.  Change in Control shall be deemed to have occurred if (i) any
          "person" (as such term is used in Sections 13(d) and 14(d) of the
          Exchange Act), other than a trustee or other fiduciary holding
          securities under an employee benefit plan of the Corporation or a
          corporation owned directly or indirectly by the stockholders of the
          Corporation in substantially the same proportions as their ownership
          of stock of the Corporation, is or becomes the "beneficial

                                       6
<PAGE>

          owner" (as defined in Rule 13d-3 under said Act), directly or
          indirectly, of securities of the Corporation representing 20% or more
          of the total voting power represented by the Corporation's then
          outstanding securities of the Corporation that generally vote in the
          election of directors, or (ii) during any period of two consecutive
          years, individuals who at the beginning of such period constitute the
          Board of Directors of the Corporation and any new director whose
          election by the Board of Directors or nomination for election by the
          Corporation's stockholders was approved by a vote of at least two-
          thirds (2/3) of the directors then still in office who either were
          directors at the beginning of the period or whose election or
          nomination for election was previously so approved (collectively, the
          "Incumbent Directors"), cease for any reason to constitute a majority
          thereof, or (iii) the stockholders of the Corporation approve a merger
          or consolidation of the Corporation with any other corporation, other
          than a merger or consolidation which would result in the securities of
          the Corporation that generally vote in the election of directors of
          the Corporation outstanding immediately prior thereto continuing to
          represent (either by remaining outstanding or by being converted into
          such types of securities of the surviving entity) at least 80% of the
          total voting power represented by the such types of securities of the
          Corporation or such surviving entity outstanding immediately after
          such merger or consolidation, or the stockholders of the Corporation
          approve a plan of complete liquidation of the Corporation or an
          agreement for the sale or disposition by the Corporation of (in one
          transaction or a series of transactions) all or substantially all the
          Corporation's assets. "Independent Legal Counsel" shall mean an
          attorney or firm of attorneys, selected in accordance with the
          provisions of this section, who shall not have otherwise performed
          services for the Corporation or Agent within the last five years
          (other than with respect to matters concerning the rights of Agent
          under this Agreement, or of other indemnitees under similar indemnity
          agreements).

          (b) In the event of a Potential Change in Control (as defined below),
          the Corporation shall, upon written request by Agent, create a trust
          for the benefit of Agent and from time to time upon written request of
          Agent shall fund such trust in an amount sufficient to satisfy any and
          all expenses reasonably anticipated at the time of each such request
          to be incurred in connection with investigating, preparing for and
          defending any claim, and any and all judgments, fines, penalties and
          settlement amounts of any and all claims from time to time actually
          paid or claimed, reasonably anticipated or proposed to be paid,
          provided that in no event shall more than $500,000 be required to be
          deposited in any trust created hereunder in excess of amounts
          deposited in respect of reasonably anticipated expenses, and provided
          further that in no event shall more than $25,000,000 in the aggregate
          be required to be deposited in any such trust and any such trusts
          created pursuant to similar indemnification agreements to which the

                                       7
<PAGE>

          Company is a party.  The amount or amounts to be deposited in the
          trust pursuant to the foregoing funding obligation shall be determined
          by the Reviewing Party, in any case in which the Independent Legal
          Counsel referred to above is involved.  The terms of the trust shall
          provide that upon a Change in Control (i) the trust shall not be
          revoked or the principal thereof invaded, without the written consent
          of the Agent, (ii) the trustee shall advance, within two business days
          of a request by the Agent, any and all expenses to the Agent (and the
          Agent hereby agrees to reimburse the trust under the circumstances
          under which the Agent would be required to reimburse the Corporation
          under Section 2(b) of this Agreement), (iii) the trust shall continue
          to be funded by the Corporation in accordance with the funding
          obligation set forth above, (iv) the trustee shall promptly pay to
          Agent all amounts for which Agent shall be entitled to indemnification
          pursuant to this Agreement or otherwise, and (v) all unexpended funds
          in such trust shall revert to the Corporation upon a final
          determination by the Reviewing Party or a court of competent
          jurisdiction, as the case may be, that Agent has been fully
          indemnified under the terms of this Agreement.  The trustee shall be
          chosen by Agent.  Nothing in this Section 11 shall relieve the
          Corporation of any of its obligations under this Agreement.  Potential
          Change in Control shall be deemed to have occurred if (i) the
          Corporation enters into an agreement, the consummation of which would
          result in the occurrence of a Change in Control; (ii) any person
          (including the Corporation) publicly announces an intention to take or
          to consider taking actions which if consummated would constitute a
          Change in Control; (iii) any person, other than a trustee or other
          fiduciary holding securities under an employee benefit plan of the
          Corporation or a corporation owned, directly or indirectly, by the
          stockholders of the Corporation in substantially the same proportions
          as their ownership of stock of the Corporation, who is or becomes the
          beneficial owner, directly or indirectly, of securities of the
          Corporation representing 9.5% or more of the combined voting power of
          the Corporation's then outstanding securities that generally vote in
          the election of directors, increases his beneficial ownership of such
          securities by five percentage points (5%) or more over the percentage
          so owned by such person; or (iv) the Board adopts a resolution to the
          effect that, for purposes of this Agreement, a Potential Change in
          Control has occurred.  Notwithstanding anything to the contrary set
          forth herein, in the event of a request by Agent to create a trust
          under this Section 11(b), the Corporation shall not be obligated to
          establish such trust if at least a majority of the Incumbent Directors
          in office at that time, and prior to the consummation of a Change in
          Control, determine that the creation of such trust would not be in the
          best interests of the Corporation.

          12.  NON-EXCLUSIVITY OF RIGHTS.  The rights of Agent hereunder shall
be in addition to any other rights Agent may have under the Corporation's By-
laws or the Code or otherwise.  To the extent that a change in the Code (whether
by statute or

                                       8
<PAGE>

judicial decision) permits greater indemnification by agreement than would be
afforded currently under the Corporation 's By-laws and this Agreement, it is
the intent of the parties hereto that Agent shall enjoy by this Agreement the
greater benefits so afforded by such change.

          13.  SURVIVAL OF RIGHTS.

          (a) The rights conferred on Agent by this Agreement shall continue
          after Agent has ceased to be a director, officer, employee or other
          agent of the Corporation or to serve at the request of the Corporation
          as a director, officer, employee or other agent of another
          corporation, partnership, joint venture, trust, employee benefit plan
          or other enterprise and shall inure to the benefit of Agent's heirs,
          executors and administrators.

          (b) The Corporation shall require any successor (whether direct or
          indirect, by purchase, merger, consolidation or otherwise) to all or
          substantially all of the business or assets of the Corporation,
          expressly to assume and agree to perform this Agreement in the same
          manner and to the same extent that the Corporation would be required
          to perform if no such succession had taken place.

          14.  SEPARABILITY.  Each of the provisions of this Agreement is a
separate and distinct agreement and independent of the others, so that if any
provision hereof shall be held to be invalid for any reason, such invalidity or
unenforceability shall not affect the validity or enforceability of the other
provisions hereof.  Furthermore, if this Agreement shall be invalidated in its
entirety on any ground, then the Corporation shall nevertheless indemnify Agent
to the fullest extent provided by the Charter Documents, the Code or any other
applicable law.

          15.  BURDEN OF PROOF.  In connection with any determination by the
Reviewing Party or otherwise as to whether Agent is entitled to be indemnified
hereunder the burden of proof shall be on the Corporation to establish that
Agent is not so entitled.

          16.  PERIOD OF LIMITATIONS.  No legal action shall be brought and no
cause of action shall be asserted by or in the right of the Company against
Agent, Agent's spouse, heirs, executors or personal or legal representatives
after the expiration of two years from the date of accrual of such cause of
action, and any claim or cause of action of the Corporation shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two-year period; provided, however, that if any shorter
period of limitations is otherwise applicable to any such cause of action such
shorter period shall govern.

          17.  ENTIRE AGREEMENT; EFFECTIVENESS.  This Agreement contains the
entire agreement of the parties hereto, and supersedes any and all prior

                                       9
<PAGE>

agreements and understandings, both oral and written, between the parties with
respect to the subject matter hereof.

          18.  GOVERNING LAW.  This Agreement shall be interpreted and enforced
in accordance with the laws of the State of Delaware.

          19.  AMENDMENT AND TERMINATION.  No amendment, modification,
termination or cancellation of this Agreement shall be effective unless in
writing signed by both parties hereto.

          20.  IDENTICAL COUNTERPARTS.  This Agreement may be executed in one or
more counterparts, each of which shall for all purposes be deemed to be an
original but all of which together shall constitute but one and the same
Agreement.

          21.  HEADINGS.  The headings of the sections of this Agreement are
inserted for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction hereof.

          22.  NOTICES.  All notices, requests, demands and other communications

                              EMPLOYMENT AGREEMENT

       THIS AGREEMENT is entered into as of the 18th day of September, 2000
(the "Effective Date"), by and between Donald Listwin (the "Executive") and
Phone.com, Inc., a Delaware corporation (the "Corporation").

       For ease of reference, this Agreement is divided into the following
parts:

FIRST PART:   TERM OF EMPLOYMENT, DUTIES AND SCOPE, COMPENSATION AND BENEFITS
              DURING EMPLOYMENT

SECOND PART:  COMPENSATION AND BENEFITS IN CASE OF INVOLUNTARY TERMINATION

THIRD PART:   COMPENSATION AND BENEFITS IN CASE OF A CHANGE IN CONTROL

FOURTH PART:  PARACHUTE PAYMENTS, CONFIDENTIAL INFORMATION, SUCCESSORS,
              MISCELLANEOUS PROVISIONS, SIGNATURE PAGE
<PAGE>

FIRST PART:   TERM OF EMPLOYMENT, DUTIES AND SCOPE, COMPENSATION AND BENEFITS
              DURING EMPLOYMENT

Section 1.  Term of Employment
------------------------------

(a)  At-Will.  Subject to the terms and conditions of this Agreement,
     -------
     Executive's employment with the Corporation is "at will" and Executive or
     the Corporation are free to terminate the employment relationship at any
     time, with or without Cause upon at least thirty (30) days written notice.

(b)  Termination for Cause.  The Corporation may terminate the Executive's
     ---------------------
     employment at any time for Cause.  For all purposes under this Agreement,
     "Cause" shall mean (1) a willful failure by the Executive to substantially
     perform the Executive's duties under this Agreement, other than a failure
     resulting from the Executive's complete or partial incapacity due to
     physical or mental illness or impairment, (2) a willful act by the
     Executive that constitutes gross misconduct and that is materially
     injurious to the Corporation, (3) a willful breach by the Executive of a
     material provision of this Agreement, (4) a material and willful violation
     of a federal or state law or regulation applicable to the business of the
     Corporation that is materially and demonstrably injurious to the
     Corporation, or (5) a material failure to achieve such reasonable financial
     and other performance measures as shall be agreed upon by the Compensation
     Committee of the Board of Directors and the Executive; all as determined by
     the Compensation Committee of the Board of Directors in good faith;
     provided, however, that failure of the parties to reasonably agree to such
     performance measures shall not be grounds for termination for cause.__No
     act, or failure to act, by the Executive shall be considered "willful"
     unless committed without good faith and without a reasonable belief that
     the act or omission was in the Corporation's best interest.

(c)  Termination for Disability.  The Corporation may terminate the Executive's
     --------------------------
     employment for Disability by giving the Executive not less than thirty-(30)
     day's advance written notice.  For all purposes under this Agreement,
     "Disability" shall mean that the Executive, at the time the notice is
     given, has been unable to perform the Executive's duties under this
     Agreement for a period of not less than six (6) consecutive months as a
     result of the Executive's incapacity due to physical or mental illness.  In
     the event that the Executive resumes the performance of substantially all
     of the Executive's duties under this Agreement before the termination of
     the Executive's employment under this Section 1 becomes effective, the
     notice of termination shall automatically be deemed to have been revoked.

(d)  Termination of Agreement.  This Agreement shall expire when all obligations
     of the parties hereunder have been satisfied.
<PAGE>

Section 2.  Duties and Scope of Employment
------------------------------------------

(a)  Position.  The Corporation agrees to employ the Executive in the positions
     --------
     of President and Chief Executive Officer ("PCEO").  Executive shall be
     given such duties, responsibilities and authorities as are appropriate to
     his position.  Executive shall also serve as a Director on the
     Corporation's Board of Directors (the "Board").

(b)  Obligations.  During the Agreement, the Executive shall devote the
     -----------
     Executive's full business efforts and time to the business and affairs of
     the Corporation as needed to carry out his duties and responsibilities
     hereunder subject to the overall supervision of the Board.  The foregoing
     shall not preclude the Executive from engaging in appropriate civic,
     charitable or religious activities or from devoting a reasonable amount of
     time to private investments or from serving on the boards of directors of
     other entities, as long as such activities and service do not interfere or
     conflict with the Executive's responsibilities to the Corporation.

Section 3.  Base Compensation
-----------------------------

During the Agreement, the Corporation agrees to pay the Executive as
compensation for services a base salary at the annual rate of $250,000, or at
such higher rate as the Compensation Committee of the Board may determine from
time to time.  Such salary shall be payable in accordance with the standard
payroll procedures of the Corporation. The annual compensation specified in this
Section 3, together with any increases in such compensation that the
Compensation Committee of the Board may grant from time to time, is referred to
in this Agreement as "Base Compensation."

Section 4.  Incentive Compensation
----------------------------------

During the Agreement, the Corporation shall award the Executive annual incentive
compensation ("Incentive Compensation") based upon a target which shall be at
least 50% of the Base Compensation, with the actual annual incentive award
determined in accordance with the achievement of financial and other performance
measures.  Executive shall also have the opportunity to earn two (2) times the
annual target based upon attainment of objectives defined by the Compensation
Committee. A minimum bonus equal to at least the target bonus shall be
guaranteed and paid in full as soon as practicable after the end of fiscal year
2001.  Any compensation paid to the Executive as Incentive Compensation shall be
in addition to the Base Compensation.  The Compensation Committee of the Board
will review the Executive's Incentive Compensation annually to ensure that the
target remains competitive.

Section 5.  Equity Compensation
-------------------------------

(a)  Stock Options.  Executive will be granted six (6) million stock options to
     -------------
     purchase the Corporation's common stock in accordance with the terms and
     conditions of the applicable stock option agreements associated therewith.
     The per share exercise price for such options shall be the closing trading
     price on the Effective Date.  Such options shall
<PAGE>

     vest as to twenty-five percent (25%) of the options on the first
     anniversary of the Effective Date and ratably thereafter at the rate of
     1/48 of such option award per month.

(b)  Other Equity Awards.  The Executive shall be considered for awards under
     -------------------
     the Corporation's existing and any new compensation and benefit plans in
     order to ensure that Executive's long-term incentives are competitive.

Section 6.  Executive Benefits
------------------------------

During the Agreement, the Executive shall be eligible to participate in all
employee and executive benefit plans and executive compensation programs
maintained by the Corporation, including (without limitation) savings or profit-
sharing plans, deferred compensation plans, stock option, incentive or other
bonus plans, life, disability, health, accident and other insurance programs,
and similar plans or programs.  Executive shall also be covered under the
Corporation's standard director and officer insurance and indemnification
programs.

Section 7.  Business Expenses and Travel
----------------------------------------

While rendering services to the Corporation, the Executive is authorized to
incur and shall be reimbursed for all necessary and reasonable travel,
entertainment and other business expenses.

Section 8.  Death or Disability
-------------------------------

If Executive's employment with the Corporation is terminated at any time due to
death or Disability, Executive shall receive (a) one (1) year of health
coverage, comparable to that provided to other senior executives of the
Corporation, for himself (if termination was due to Disability) and his family
and (b) continuance of life insurance coverage on his life for one (1) year
following termination (if termination was due to Disability).  To the extent
that the Corporation finds it undesirable to cover the Executive under the group
life insurance and health plans of the Corporation, the Corporation shall
provide the Executive (at its own expense) with the same level of coverage under
individual policies.
<PAGE>

SECOND PART:  COMPENSATION AND BENEFITS IN CASE OF INVOLUNTARY TERMINATION

Section 9.  Terminations
------------------------

This Second Part of the Agreement, consisting of Sections 9 through 10,
describes the benefits and compensation, if any, payable in case of a Qualifying
Termination of employment.  The Third Part of the Agreement, consisting of
Sections 11 and 12, describes benefits and compensation, if any, payable in case
of a Change in Control.

Section 10.  Termination Without Cause; Involuntary Termination
---------------------------------------------------------------

In the event that, during the Agreement, the Executive's employment terminates
in a Qualifying Termination, as defined in Section 10(a), then, after executing
the release of claims described in Section 10(c), the Executive shall be
entitled to receive the payments and benefits described in Section 8 and Section
10(b).

(a)  Qualifying Termination.  A Qualifying Termination occurs if:
     ----------------------

     (1)  The Corporation terminates the Executive's employment for any reason
          other than Cause, Death or Disability; or

     (2)  The Executive experiences an Involuntary Termination not resulting
          from a Change in Control.  For purposes of this Agreement, Involuntary
          Termination shall mean the occurrence of any of the following without
          the Executive's prior written consent:  (i) a greater than 10%
          reduction in Executive's base compensation, incentive compensation
          target and benefits except if a majority of the Board of Directors
          vote to reduce the salary of the Executive and the rest of the
          Corporation's executive officers by the same percentage amount for the
          same time period, (ii) a material change in Executive's status or his
          responsibilities (excluding loss of title as President of the
          Corporation), (iii) the Corporation's failure to continue Executive as
          its CEO, (iv) the Corporation's failure to nominate Executive for re-
          election as a member of the Board of Directors (unless Executive's
          employment is terminated for Cause), (v) if Executive is not at all
          times the Chief Executive Officer of the Corporation's ultimate parent
          entity (if any), or (vi) a requirement to relocate, except for office
          relocations that would not increase the Executive's one-way commute
          distance by more than thirty (30) miles.  For purposes of greater
          clarity, termination for Cause, death or Disability shall not give
          rise to an Involuntary Termination.

(b)  Payments and Benefits.  The Corporation shall pay to the Executive
     ---------------------
     following the date of termination of employment the following aggregate
     payments and benefits spread ratably over the succeeding twelve (12)
     months, in accordance with standard payroll procedures:

     (1)  One (1) times the Executive's Base Compensation in effect on the date
          of the termination of employment;
<PAGE>

     (2)  One (1) times the Executive's target Incentive Compensation for the
          year in which Executive's employment is terminated;

     (3)  50% of Executive's then unvested stock options shall become vested and
          Executive shall have one (1) year after the date of Qualifying
          Termination to exercise all vested options and Executive's remaining
          unvested options, if any, shall not expire until the earlier of (i)
          their original expiration date or (ii) one (1) year after the date of
          Qualifying Termination; and

     (4)  The same level of health and life insurance coverage provided under
          Section 8 above.  This coverage will be provided for one (1) year
          after termination of employment with COBRA benefits to begin
          thereafter.  The obligation of the Corporation to provide continued
          health and life insurance benefits under this Section 10 shall cease
          if Executive becomes employed by another employer and such employer
          provides the Executive with life insurance and health plan coverage
          that is comparable to the coverage contemplated by this Section 10.

(c)  Release of Claims.  As a condition to the receipt of the payments and
     -----------------
     benefits described in this Section 10, the Executive shall be required to
     execute a release of all claims arising out of the Executive's employment
     or the termination thereof including, but not limited to, any claim of
     discrimination under state or federal law, but excluding claims for
     indemnification from the Corporation under any indemnification agreement
     with the Corporation, its certificate of incorporation and by-laws or
     applicable law or claims for directors and officers' insurance coverage.

(d)  Conditions to Receipt of Payments and Benefits.  In view of Executive's
     ----------------------------------------------
     position and his access to Confidential Information, as a condition to the
     receipt of cash payments and health and life insurance benefits described
     in this Section 10, the Executive shall not, without the Corporation's
     written consent, directly or indirectly, alone or as a partner, joint
     venturer, officer, director, Executive, consultant, agent or stockholder
     (other than a less than 5% stockholder of a publicly traded company) (i)
     engage in any activity which is in competition with the business, the
     products or services of the Corporation (a list of competitors and
     competitive products and services, which may be updated, is attached
     hereto), (ii) solicit any of the Corporation's Executives, consultants or
     customers, (iii) hire any of the Corporation's Executives or consultants in
     an unlawful manner or actively encourage Executives or consultants to leave
     the Corporation, or (iv) otherwise breach his Confidential Information
     obligations.

(e)  No Mitigation.  Except as provided in Section 10(b)(4), the Executive shall
     -------------
     not be required to mitigate the amount of any payment or benefit
     contemplated by this Section 10, nor shall any such payment or benefit be
     reduced by any earnings or benefits that the Executive may receive from any
     other source.
<PAGE>

THIRD PART:  COMPENSATION AND BENEFITS IN CASE OF A CHANGE IN CONTROL

Section 11.  Change in Control
------------------------------

(a)  If Executive is still employed by the Corporation and there is a Change in
     Control, 50% of Executive's then unvested stock options shall become
     vested.  His remaining unvested stock options shall continue to vest at the
     same rate of vesting as before the Change in Control subject to Section
     11(b) below.

(b)  If a Qualifying Termination occurs in connection with a Change in Control
     or within eighteen (18) months after a Change in Control, the Executive
     will receive a cash severance payment equal to one (1) times the sum of his
     Base Compensation and target Incentive Compensation less any severance
     payments previously made under Section 10(b) above.  Such severance will be
     paid in a lump sum within ten (10) days of the Qualifying Termination.
     Executive shall receive the same health and life insurance benefits
     provided in Section 8.  Additionally, all of Executive's unvested stock
     options, if any, shall vest in full and Executive shall have one (1) year
     after the date of Qualifying Termination to exercise his vested options.

Section 12.  Definition of Change in Control
--------------------------------------------

For all purposes under this Agreement, "Change in Control" shall be as defined
below.

          (i) The stockholders of the Corporation approve an agreement for the
sale of all or substantially all of the assets of the Corporation to a person or
entity; or

          (ii) The stockholders of the Corporation approve a merger or
consolidation of the Corporation with any other corporation, other than a merger
or consolidation which would result in the voting securities of the Corporation
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) at least fifty percent (50%) of the total voting power
represented by the voting securities of the Corporation or such surviving entity
outstanding immediately after such merger or consolidation;

          (iii)  Completion of a tender or exchange offer or other transaction
or series of transactions by a person or entity that results in less than a
majority of the outstanding voting shares of the surviving corporation being
held, immediately after such transaction or series of transactions, by the
holders of the voting shares of the Corporation outstanding immediately prior to
such transaction or series of transactions.

     Notwithstanding the foregoing, a "Change in Control" shall not be deemed to
have occurred by virtue of the consummation of any transaction or series of
integrated transactions (i) immediately following which the record holders of
the common stock of the Corporation immediately prior to such transaction or
series of transactions continue to have substantially the

                                       7
<PAGE>

same proportionate ownership in an entity which owns all or substantially all of
the assets of the Corporation immediately following such transaction or series
of transactions or (ii) involving the proposed merger between the Corporation
and Software.com, Inc.; or

               (iv)  Approval by the stockholders of the Corporation of a
          complete liquidation or dissolution of the Corporation.

                                       8
<PAGE>

FOURTH PART:  PARACHUTE PAYMENTS, CONFIDENTIAL INFORMATION, SUCCESSORS,
               MISCELLANEOUS PROVISIONS, SIGNATURE PAGE

Section 13.  Parachute Payments
-------------------------------

     In the event that the severance and other benefits provided for in this
Agreement or otherwise payable to the Executive (i) constitute "parachute
payments" within the meaning of Section 280G of the Internal Revenue Code of
1986, as amended (the "Code"), and (ii) but for this Section 13, would be
subject to the excise tax imposed by Section 4999 of the Code (or any
corresponding provisions of state income tax law), then the Executive's
severance benefits under Section 11 shall be either

          (a)  delivered in full, or

          (b) delivered as to such lesser extent which would result in no
portion of such severance benefits being subject to excise tax under Section
4999 of the Code, whichever of the foregoing amounts, taking into account the
applicable federal, state and local income taxes and the excise tax imposed by
Section 4999, results in the receipt by the Executive on an after-tax-basis, of
the greater amount of severance benefits, notwithstanding that all or some
portion of such severance benefits may be taxable under Section 4999 of the
Code.  Unless the Corporation and the Executive otherwise agree in writing, any
determination required under this Section 13 shall be made in writing by the
Corporation's accountants, whose determination shall be conclusive and binding
upon the Executive and the Corporation for all purposes.  For purposes of making
the calculations required by this Section 13, the accountants may make
reasonable assumptions and approximations concerning applicable taxes and may
rely on reasonable, good faith interpretations concerning the application of
Sections 280G and 4999 of the Code.  The Corporation and the Executive shall
furnish to the accountants such information and documents as the accountants may
reasonably request in order to make a determination under this Section 13.  The
Corporation shall bear all costs the accountants may reasonably incur in
connection with any calculations contemplated by this Section 13.  In the event
that subsection (a) above applies, then Executive shall be responsible for any
excise taxes imposed with respect to such severance and other benefits.  In the
event that subsection (b) above applies, then each benefit provided hereunder
shall be proportionately reduced to the extent necessary to avoid imposition of
such excise taxes.

Section 14.  Confidential Information
-------------------------------------

The Corporation and the Executive will enter into the Corporation's standard
Employee Inventions and Assignment Agreement which shall govern use by the
Executive of the Corporation's confidential information.

Section 15.  Successors
-----------------------

(a)  Corporation's Successors.  The Corporation shall require any successor
     ------------------------
     (whether direct or indirect and whether by purchase, lease, merger,
     consolidation, liquidation or otherwise)

                                       9
<PAGE>

     to all or substantially all of the Corporation's business and/or assets, by
     an agreement in substance and form satisfactory to the Executive, to assume
     this Agreement and to agree expressly to perform this Agreement in the same
     manner and to the same extent as the Corporation would be required to
     perform it in the absence of a succession. The Corporation's failure to
     obtain such agreement prior to the effectiveness of a succession shall be a
     breach of this Agreement and shall entitle the Executive to all of the
     compensation and benefits to which the Executive would have been entitled
     hereunder if the Corporation had involuntarily terminated the Executive's
     employment without Cause or Disability, on the date when such succession
     becomes effective. For all purposes under this Agreement, the term
     "Corporation" shall include any successor to the Corporation's business
     and/or assets that executes and delivers the assumption agreement described
     in this Section 15(a) or that becomes bound by this Agreement by operation
     of law.

(b)  Executive's Successors.  This Agreement and all rights of the Executive
     ----------------------
     hereunder shall inure to the benefit of, and be enforceable by, the
     Executive's personal or legal representatives, executors, administrators,
     successors, heirs, distributees, devisees and legatees.

     referenced above, and the Employee Inventions and Assignment Agreement
     supersede in their entirety any agreements between the Executive and the

     Agreement.  As of the Effective Date, any such agreement shall terminate
     without any further obligation by either party thereto, and the Executive
     hereby relinquishes any further rights that the Executive may have had
     under any such prior agreement.

(e)  Choice of Law.  The validity, interpretation, construction and performance
     -------------
     of this Agreement shall be governed by the laws of the State of California,
     irrespective of California's choice-of-law principles.

(f)  Severability.  The invalidity or unenforceability of any provision or
     ------------
     provisions of this Agreement shall not affect the validity or
     enforceability of any other provision hereof, which shall remain in full
     force and effect.

     16(h) shall be void.

     -----------------------------
     to life insurance and health plan coverage under more than one provision
     hereunder, only one provision shall apply, and neither the periods of
     coverage nor the amounts of benefits shall be additive.

(l)  Discharge of Responsibility. The payments under this Agreement, when made
     ---------------------------
     in accordance with the terms of this Agreement shall fully discharge all
     responsibilities of the Corporation to the Executive that existed at the
