determined in accordance with the provisions of Code Section 280G(d)(4),
utilizing a discount rate equal to one hundred twenty percent (120%) of the
applicable Federal rate in effect at the time of such determination, compounded
semi-annually to the effective date of the Change in Control.

terminate his employment for Cause pursuant to such provisions and thirty (30)
days to correct any condition giving rise to Cause for termination. In the event
that the Executive fails satisfactorily to correct such conditions of which he
is notified, which determination shall be made by the Board, his employment
shall be terminated.

the Employment Period, and the Executive shall not retain any copies or excerpts
of the returned items.

time of such termination of employment, and the Executive shall not have more
than the period of time specified in the applicable stock option agreement for

                     PART THREE - CHANGE IN CONTROL PAYMENTS

               This Part Three sets forth certain payments and benefits to which

at the time of a Change in Control but not otherwise vested and exercisable for
all the shares of Common Stock subject to that Option will, immediately prior to
the effective date of that Change in Control, vest and become exercisable for
all of the shares of Common Stock at the time subject to the Option and may be
exercised for any or all of those shares as fully-vested shares of Common Stock;
provided and only if the following conditions are satisfied with respect to that
Change in Control:

                    (i)   the Option is not to be assumed by the successor
          corporation (or its parent company) or otherwise continued in effect
          pursuant to the terms of the Change in Control transaction, and

                    (ii)  the Option is not to be replaced with a substitute
          option or cash incentive plan that preserves the spread existing at
          the time of the Change in Control on any shares for which that Option
          is not otherwise at that time vested and exercisable (the excess of
          the Fair Market Value of those shares over the applicable option
          exercise price) and which vests at the same or faster rate as the
          vesting schedule applicable to that Option.

               13.  Entitlement to Change in Control Severance Payments. Should
the Executive's employment pursuant to this Agreement terminate by reason of an
Involuntary Termination within eighteen (18) months after such Change in
Control, then the Executive shall become entitled to receive the Change in
Control Severance Payments set forth in Paragraph 14, subject to his compliance
with the following requirement:

                    -    The Executive shall, at the time of such Involuntary
          Termination, execute and deliver to the Corporation a general release
          which shall become effective under applicable law and pursuant to
          which the Executive releases the Corporation and its officers,
          directors, employees and agents from any and all claims the Executive
          may otherwise have with respect to the terms and conditions of his
          employment with the Corporation and the termination of that employment
          (other than his rights pertaining to the Change in Control Severance
          Payments provided under this Part Three).

               The Change in Control Severance Payments provided under this Part
Three shall be in lieu of any other severance benefits to which the Executive
might otherwise, by reason of the termination of his employment in connection
with a Change in Control, be entitled under any other severance plan, program or
arrangement of the Corporation.

               14.  Nature of Change in Control Severance Payments. The Change
in Control Severance Payments to which the Executive shall receive under this
Part Three shall consist of the following payments and benefits:

                    (a)  Lump Sum Payment. Executive shall be entitled to a lump
sum cash payment equal to one (1) times the sum of (i) the annual rate of base
salary in effect for him under Paragraph 3 at the time of his Involuntary
Termination and (ii) the Target Bonus in effect for him for the fiscal year of
the Corporation in which such Involuntary Termination occurs. Such lump sum
payment shall be made within three (3) business days following the date the
general release required of the Executive pursuant to Paragraph 13 and shall be
subject to all applicable withholding requirements as set forth in Paragraph
3.C.

                    (b)  Target Bonus Pro-Ration. For each full or partial month
of employment which the Executive completes with the Corporation in the fiscal
year in which his Involuntary Termination occurs, the Executive shall also be
entitled to receive a lump sum cash payment equal to one-twelfth (1/12th) of the
annual Target Bonus in effect for him for that year. Such lump sum payment shall
be made within three (3) business days following the date the general release
required of the Executive pursuant to Paragraph 13 and shall be subject to all
applicable withholding requirements as set forth in Paragraph 3.C.

                    (c)  Health Care Coverage. Continued health care coverage
under the Corporation's medical plan shall be provided, without charge, to the
Executive and his eligible dependents upon his election to receive such
continued health care coverage under Code Section 4980B ("COBRA"). Such
Corporation-paid coverage shall continue until the earlier of (i) the expiration
of the eighteen (18)-month period measured from the first day of the calendar
month following the calendar month in which his Involuntary Termination occurs
or (ii) the first date on which the Executive and his eligible dependents are
covered under another employer's health benefit program without exclusion for
any pre-existing medical condition. Any additional health care coverage to which
the Executive and his dependents may be entitled under COBRA following the
period of such Corporation-paid coverage shall be at the Executive's sole cost
and expense. However, should the Executive not be covered under another
employer's health plan at the time the initial eighteen (18)-month period of
Corporation-paid coverage expires, then the Corporation shall, for up to an
additional six (6)-month period thereafter, reimburse the Executive for any
premiums paid during such period on his continued COBRA coverage (if any) or the
individual health care coverage policy issued to him in conversion of his COBRA
coverage.

                    (d)  Option Acceleration. Each Option outstanding at the
time of such Involuntary Termination, to the extent not otherwise vested and
exercisable for all the shares subject to that Option, will immediately vest and
become exercisable for all those option shares and may be exercised for any or
all of those shares as fully vested shares.

                                       8

<PAGE>

                    (e)  Extension of Exercise Period. For each outstanding
Option (i) which is granted to the Executive on or after September 13, 2002 or
(ii) which is outstanding on that date and is not otherwise listed as an
excluded Option on attached Schedule I, the Executive shall have until the
earlier of (i) the expiration of the twelve (12)-month period measured from the
date of his Involuntary Termination or (ii) the expiration date of the option
term in which to exercise that Option. To the extent the exercise period of any
existing Option which is an incentive stock option under the federal income tax
laws is so extended, that Option shall be deemed to be regranted on the date of
this Agreement and may accordingly fail to retain such incentive stock option
status by reason of the One Hundred Thousand Dollar ($100,000) limit on the
initial exercisability of incentive stock options per calendar year or because
the exercise price of that Option is below the Fair Market Value of the Common
Stock on September 13, 2002. Accordingly, if the Option does lose such incentive
stock option status, the Executive shall recognize immediate taxable income upon
the subsequent exercise of that Option in an amount equal to the Fair Market
Value of the purchased shares less the exercise price paid for those shares, and
the Executive will have to satisfy all applicable income and employment
withholding taxes at the time of such exercise. To the extent any such Option
does retain its incentive stock option status, the Executive shall not be
entitled to long-term capital gain treatment upon the subsequent sale of any
shares purchased under that Option unless such sale occurs more than two (2)
years after the deemed September 13, 2002 regrant date of that Option and more
than one (1) year after the date such Option is exercised for those shares.

                         PART FOUR - SPECIAL TAX PAYMENT

               15.  Special Tax Gross-Up. In the event that one or more of the
Acquisition-Accelerated Options or any of the Change in Control Severance
Payments to which the Executive becomes entitled under Part Three of this
Agreement or any Other Parachute Payments are deemed, in the opinion of the
Independent Auditors or by the Internal Revenue Service, to constitute an excess
parachute payment under Code Section 280(G), then the Executive shall be
entitled to receive from the Corporation an additional payment (the "Gross-Up
Payment") in a dollar amount determined pursuant to the following formula,
provided and only if the general release required of the Executive pursuant to
Paragraph 13 has become effective:

                    X  =  Y  /  [1 - (A + B + C)], where

                    X is the total dollar payment  of the Gross-up Payment.

                    Y is the total excise tax, together with all applicable
                    interest and penalties (collectively, the "Excise Tax"),
                    imposed on the Executive pursuant to Code Section 4999 (or
                    any successor provision) with respect to the excess
                    parachute payment attributable to (i) one or more of the
                    Change in Control Severance Payments provided the Executive
                    under Part Three of this Agreement, (ii) his
                    Acquisition-Acceleration Options and (iii) any Other
                    Parachute Payments.

                    A is the Excise Tax rate in effect under Code Section 4999
                    for such excess parachute payment,

                    B is the highest combined marginal federal income and
                    applicable state income tax rate in effect for the Executive
                    for the calendar year in which the Gross-Up Payment is made,
                    determined after taking into account the deductibility of
                    state income taxes against federal income taxes to the
                    extent actually allowable for that calendar year, and

                    C is the applicable Hospital Insurance (Medicare) Tax Rate
                    in effect for the Executive for the calendar year in which
                    the Gross-Up Payment is made.

               16.  Determination Procedures. All determinations required to be
made under this Part Four shall be made by the Independent Auditors in
accordance with the following procedures:

                                        9

<PAGE>

                    (a)  Within ten (10) business days after each receipt of
written notice from the Corporation or the Executive that a Change in Control
Severance Payment or Other Parachute Payment has or is to be made or that one or
more Options have or will become Acquisition-Accelerated Options, then the
Independent Auditors shall provide both the Executive and the Corporation with a
written determination of the Parachute Payment attributable to that Change in
Control Severance Payment or Other Parachute Payment or the Option Parachute
Payment attributable to those Acquisition-Accelerated Options, together with
detailed supporting calculations with respect to the Gross-Up Payment to which
the Executive is entitled by reason of those various Parachute Payments. The
Corporation shall pay the resulting Gross-Up Payment to the Executive within
three (3) business days after receipt of such determination or (if later)
contemporaneously with the Change in Control Severance Payment, Other Parachute
Payment or Acquisition-Accelerated Options triggering such Gross-Up Payment.

                    (b)  In the event temporary, proposed or final Treasury
Regulations in effect at the time under Code Section 280G (or applicable
judicial decisions) specifically address the status of any Change in Control
Severance Payment, Acquisition-Accelerated Option or Other Parachute Payment or
the method of valuation therefor, the characterization afforded to such payment
by the Regulations (or such decisions) shall, together with the applicable
valuation methodology, be controlling. All other determinations by the
Independent Auditors shall be made on the basis of "substantial authority"
(within the meaning of Section 6662 of the Code).

                    (c)  The Corporation and the Executive shall each provide
the Independent Auditors with access to and copies of any books, records and
documents in their possession which may be reasonably requested by the
Independent Auditors and shall otherwise cooperate with the Independent Auditors
in connection with the preparation and issuance of the determinations
contemplated by this Part Four.

                    (d)  All fees and expenses of the Independent Auditors and
the appraisers shall be borne solely by the Corporation, and to the extent those
fees or expenses are treated as a Parachute Payment, they shall be taken into
account in the calculation of the Gross-Up Payment to which the Executive is
entitled under this Part Four.

               17.  Additional Claims. The Executive shall provide written
notification to the Corporation of any claim made by the Internal Revenue
Service which would, if successful, require the payment by the Corporation of an
additional Gross-Up Payment. Such notification shall be given as soon as
practicable after the Executive is informed in writing of such claim and shall
apprise the Corporation of the nature of such claim and the date on which such
claim is requested to be paid. The Executive shall not pay such claim prior to
the expiration of the thirty (30)-day period following the date on which such
notice is given to the Corporation (or such shorter period ending on the date
that any payment of taxes, interest and/or penalties with respect to such claim
is due). Prior to the expiration of such thirty (30)-day or shorter period, the
Corporation shall ether (i) make the additional Gross-Up Payment to the
Executive attributable to the Internal Revenue Service claim or (ii) provide
written notice to the Executive that the Corporation shall contest the claim on
the Executive's behalf. In the event, the Corporation provides the Executive
with such written notice, the Executive shall:

               (A)  provide the Corporation with any information reasonably
requested by the Corporation relating to such claim;

               (B)  take such action in connection with contesting such claim as
the Corporation may reasonably request in writing from time to time, including
(without limitation) accepting legal representation with respect to such claim
by an attorney reasonably selected by the Corporation and reasonably
satisfactory to the Executive, with the fees and expenses of such attorney to be
the sole responsibility of the Corporation without any tax implications to the
Executive in accordance with the same tax indemnity/gross-up arrangement as in
effect under subparagraph (D) below;

               (C)  cooperate with the Corporation in good faith in order to
effectively contest such claim; and

                                       10

<PAGE>

                    (D)  permit the Corporation to participate in any
proceedings relating to such claim; provided, however, that the Corporation
shall bear and pay directly all additional Excise Taxes imposed upon the
Executive and all costs, legal fees and other expenses (including additional
interest and penalties) incurred in connection with such contest and shall
indemnify the Executive for and hold him harmless from, on an after-tax basis,
any additional Excise Tax (including interest and penalties) imposed upon the
Executive and any Excise Tax or income or employment tax (including interest and
penalties) attributable to the Corporation's payment of that additional Excise
Tax on the Executive's behalf or imposed as a result of such representation and
payment of all related costs, legal fees and expenses. The amounts owed to the
Executive by reason of the foregoing shall be paid to him or on his behalf as
they become due and payable. Without limiting the foregoing provisions of this
subparagraph (D), the Corporation shall control all proceedings taken in
connection with such contest and, at its sole option, may pursue or forgo any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at the Corporation's sole
option, either direct the Executive to pay the tax claimed and sue for a refund
or contest the claim in any permissible manner, and the Executive shall
prosecute such contest to a determination before any administrative tribunal, in
a court of initial jurisdiction and in one or more appellate courts, as the
Corporation shall determine; provided, however, that should the Corporation
direct the Executive to pay such claim and sue for a refund, the Corporation
shall advance the amount of such payment to the Executive, on an interest-free
basis, and shall indemnify the Executive for and hold him harmless from, on an
after-tax basis, any Excise Tax or income or employment tax (including interest
or penalties) imposed with respect to such advance or with respect to any
imputed income with respect to such advance or any income resulting from the
Corporation's forgiveness of such advance; provided, further, that the
Corporation's control of the contest shall be limited to issues with respect to
which a Gross-Up Payment would be payable hereunder, and the Executive shall be
entitled to settle or contest, as the case may be, any other issue raised by the
Internal Revenue Service or any other taxing authority.

                       PART FIVE -- RESTRICTIVE COVENANTS

               18.  Non-Solicitation. For a period of one (1) year following the
Executive's termination of employment with the Corporation, whether or not in
connection with a Change in Control, the Executive shall not encourage or
solicit any of the Corporation's employees to leave the Corporation's employ for
any reason or interfere in any other manner with employment relationships at the
time existing between the Corporation and its employees.

                      PART SIX -- MISCELLANEOUS PROVISIONS

               19.  Continued Indemnification. The indemnification provisions
for Officers and Directors under the Corporation's bylaws and Directors and
Officers Liability Insurance shall (to the maximum extent permitted by law) be
extended to the Executive during the period following his resignation or
termination of employment for any reason (other than a Termination for Cause),
whether or not in connection with a Change in Control, with respect to all
matters, events or transactions occurring or effected during the Executive's
period of employment with the Corporation.

               20.  Cessation of Severance Benefits. In the event of a material
breach by the Executive of any of his obligations under Paragraph 9, 10 or 18 of
this Agreement or his Proprietary Information and Inventions Agreement with the
Corporation, he shall cease to be entitled to any further severance benefits
under Part Three of this Agreement, including (without limitation) any
subsequent right to exercise any outstanding Options or to receive any further
salary/target bonus payments or continued health care coverage at the
Corporation's expense. In no event shall the Executive be entitled to any
benefits under Part Three of this Agreement if his employment ceases by reason
of a Termination for Cause or if he voluntarily resigns other than for a reason
which qualifies as grounds for an Involuntary Termination.

               21.  No Mitigation Duty. The Corporation shall not be entitled to
set off any of the following amounts against the payments or benefits to which
the Executive may become entitled under Part Three of this Agreement: (i) any
amounts which the Executive may subsequently earn through other employment or
service

                                       11

<PAGE>

following his termination of employment with the Corporation or (ii) any amounts
which the Executive might have potentially earned in other employment or service
had he sought such other employment or service.

               22.  Death. Should the Executive die before he receives the full
amount of payments and benefits to which he may become entitled under Part Three
of this Agreement, then the balance of such payments shall be made, on the due
dates hereunder had the Executive survived, to the executors or administrators
of his estate.

               23.  Successors and Assigns. The provisions of this Agreement
shall inure to the benefit of, and shall be binding upon, (i) the Corporation
and its successors and assigns, including any successor entity by merger,
consolidation or transfer of all or substantially all of the Corporation's
assets (whether or not such transaction constitutes a Change in Control), and
(ii) the Executive, the personal representative of his estate and his heirs and
legatees.

               24.  General Creditor Status. The benefits to which the Executive
may become entitled under Part Three of this Agreement shall be paid, when due,
from the Corporation's general assets, and no trust fund, escrow arrangement or
other segregated account shall be established as a funding vehicle for such
payments. Accordingly, the Executive's right (or the right of the executors or
administrators of the Executive's estate) to receive such benefits shall at all
times be that of a general creditor of the Corporation and shall have no
priority over the claims of other general creditors.

               25.  Notices.

               A.   Any and all notices, demands or other communications
required or desired to be given hereunder by any party shall be in writing and
shall be validly given or made to another party if delivered either personally
or if deposited in the United States mail, certified or registered, postage
prepaid, return receipt requested. If such notice, demand or other communication
shall be delivered personally, then such notice shall be conclusively deemed
give at the time of such personal delivery. If such notice, demand or other
communication is given by mail, such notice shall be conclusively deemed given
forty-eight (48) hours after deposit in the United States mail addressed to the
party to whom such notice, demand or other communication is to be given as
hereinafter set forth:

               To the Corporation:          Legato Systems, Inc.
                                            2350 West El Camino Real
                                            Mountain View, CA 94040
                                            Attention: General Counsel

               To Executive:                David L. Beamer
                                            2350 West El Camino Real
                                            Mountain View, CA 94040

               B.   Any party hereto may change its address for the purpose of
receiving notices, demands and other communications as herein provided by a
written notice given in the manner aforesaid to the other party hereto.

               26.  Governing Documents. This Agreement, together with (i) the
stock option agreements evidencing the Executive's currently outstanding Options
and any future Option grants, (ii) his existing Proprietary Information and
Inventions Agreement, and (iii) any outstanding promissory notes of the
Executive payable to or to the order of the Corporation, shall constitute the
entire agreement and understanding of the Corporation and the Executive with
respect to the terms and conditions of the Executive's employment with the
Corporation and the payment of severance benefits and shall supersede all prior
and contemporaneous written or verbal agreements and understandings between the
Executive and the Corporation relating to such subject matter. This Agreement
may only be amended by written instrument signed by the Executive and an
authorized officer of the Corporation. Any and all prior agreements,
understandings or representations relating to the Executive's employment with
the Corporation, other than (i) the stock option agreements evidencing the
Executive's currently outstanding Options, (ii) his existing

                                       12

<PAGE>

Proprietary Information and Inventions Agreement and (iii) his outstanding
promissory notes payable to or to the order of the Corporation, are hereby
terminated and cancelled in their entirety and are of no further force or
effect.

               27.  Governing Law. The provisions of Agreement shall be
construed and interpreted under the laws of the State of California applicable
to agreements executed and wholly performed within the State of California. If
any provision of this Agreement as applied to any party or to any circumstance
should be adjudged by a court of competent jurisdiction to be void or
unenforceable for any reason, the invalidity of that provision shall in no way
affect (to the maximum extent permissible by law) the application of such
provision under circumstances different from those adjudicated by the court, the
application of any other provision of this Agreement, or the enforceability or
invalidity of this Agreement as a whole. Should any provision of this Agreement
become or be deemed invalid, illegal or unenforceable in any jurisdiction by
reason of the scope, extent or duration of its coverage, then such provision
shall be deemed amended to the extent necessary to conform to applicable law so
as to be valid and enforceable or, if such provision cannot be so amended
without materially altering the intention of the parties, then such provision
will be stricken, and the remainder of this Agreement shall continue in full
force and effect.

               28.  Injunctive Relief. The Executive expressly agrees that the
covenants set forth in Paragraphs 9, 10 and 18 of this Agreement are reasonable
and necessary to protect the Corporation and its legitimate business interests,
and to prevent the unauthorized dissemination of Proprietary Information to
competitors of the Corporation. The Executive also agrees that the Corporation
will be irreparably harmed and that damages alone cannot adequately compensate
the Corporation if there is a violation of Paragraphs 9, 10 or 18 of this
Agreement by the Executive, and that injunctive relief against the Executive is
essential for the protection of the Corporation. Therefore, in the event of any
such breach, it is agreed that, in addition to any other remedies available, the
Corporation shall be entitled as a matter of right to injunctive relief in any
court of competent jurisdiction, plus attorneys' fees actually incurred for the
securing of such relief. Furthermore, the Executive agrees that the Corporation
shall not be required to post a bond or other collateral security with the court
if the Corporation seeks injunctive relief.

               29.  Arbitration. Each party agrees that any and all disputes
which arise out of or relate to the Executive's employment, the termination of
the Executive's employment, or the terms of this Agreement shall be resolved
through final and binding arbitration. Such arbitration shall be in lieu of any
trial before a judge and/or jury, and the Executive and Corporation expressly
waive all rights to have such disputes resolved via trial before a judge and/or
jury. Such disputes shall include, without limitation, claims for breach of
contract or of the covenant of good faith and fair dealing, claims of
discrimination, claims under any federal, state or local law or regulation now
in existence or hereinafter enacted and as amended from time to time concerning
in any way the subject of the Executive's employment with the Corporation or its
termination. The only claims not covered by this Agreement to arbitrate disputes
are: (i) claims for benefits under the unemployment insurance benefits; (ii)
claims for workers' compensation benefits under any of the Corporation's
workers' compensation insurance policy or fund; (iii) claims arising from or
relating to the non-competition provisions of this Agreement; and (iv) claims
concerning the validity, infringement, ownership, or enforceability of any trade
secret, patent right, copyright, trademark or any other intellectual property
right, and any claim pursuant to or under any existing
confidential/proprietary/trade secrets information and inventions agreement(s)
such as, but not limited to, the Proprietary Information and Inventions
Agreement. With respect to such disputes, they shall not be subject to
arbitration; rather, they will be resolved pursuant to applicable law.

               Arbitration shall be conducted in accordance with the National
Rules for the Resolution of Employment Disputes of the American Arbitration
Association ("AAA Rules"), provided, however, that the arbitrator shall allow
the discovery authorized by California Code of Civil Procedure section 1282, et
seq., or any other discovery required by applicable law in arbitration
proceedings, including, but not limited to, discovery available under the
applicable state and/or federal arbitration statutes. Also, to the extent that
any of the AAA Rules or anything in this arbitration section conflicts with any
arbitration procedures required by applicable law, the arbitration procedures
required by applicable law shall govern.

               Arbitration will be conducted in Santa Clara County, California
or, if the Executive does not reside within 100 miles of Santa Clara County at
the time the dispute arises, then the arbitration may take place in the largest
metropolitan area within 50 miles of the Executive's place of residence when the
dispute arises.

                                       13

<PAGE>

               During the course of the arbitration, the Executive and the
Corporation will each bear equally the arbitrator's fee and any other type of
expense or cost of arbitration, unless applicable law requires otherwise, and
each shall bear their own respective attorneys' fees incurred in connection with
the arbitration. The arbitrator will not have authority to award attorneys' fees
unless a statute or contract at issue in the dispute authorizes the award of
attorneys' fees to the prevailing party. In such case, the arbitrator shall have
the authority to make an award of attorneys' fees as required or permitted by
the applicable statute or contract. If there is a dispute as to whether the
Executive or the Corporation is the prevailing party in the arbitration, the
arbitrator will decide this issue.

               The arbitrator shall issue a written award that sets forth the
essential findings of fact and conclusions of law on which the award is based.
The arbitrator shall have the authority to award any relief authorized by law in
connection with the asserted claims or disputes. The arbitrator's award shall be
subject to correction, confirmation, or vacation, as provided by applicable law
setting forth the standard of judicial review of arbitration awards. Judgment
upon the arbitrator's award may be entered in any court having jurisdiction
thereof.

               30.  Counterparts. This Agreement may be executed in more than
