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

                        EXECUTIVE EMPLOYMENT AGREEMENT

        This Executive Employment Agreement ("Agreement") is made and entered
into effective as of March 23, 1998 (the "Effective Date"), by and among
VERISITY, LTD., an Israeli corporation ("Verisity-Israel"), VERISITY DESIGN,
INC., a California corporation (the "Company") and MOSHE GAVRIELOV, an
individual resident of California ("Executive"), with reference to the
following:

                                  BACKGROUND

        A.  The Company and Verisity-Israel are in the business of developing
and marketing design verification software for the semiconductor industry.

        B.  Executive has extensive experience in the semiconductor industry.

        C.  The Company desires to retain the full-time services of Executive
and Verisity-Israel desires Executive to serve as its Chief Executive Officer
without being an employee of Verisity-Israel and Executive is willing to be
employed by the Company and to serve Verisity-Israel in such capacities, on the
terms and conditions set forth in this Agreement.

        NOW THEREFORE, in consideration of the promises herein made and on the
terms and subject to the conditions herein contained, the parties hereby agree
as follows:

    1.  Employment.  The Company hereby employs Executive on the terms set forth
        ----------
herein and Executive hereby accepts such employment for an indefinite term
beginning on the Effective Date, but subject to termination as provided under
Section 6 below.

    2.  Duties.  During the period of his employment with the Company hereunder,
        ------
Executive will be employed by the Company and will report directly to the
Company's Board of Directors.  Executive will:

              (a) devote his full business time and attention, and give his best
effort and skill solely to the Company's business affairs and interests, and
shall not, without the Company's prior written approval, render to others
services of any kind for consideration or engage in any other business activity
that would

                                      -1-
<PAGE>

materially interfere with the performance of his duties under this Agreement,
provided that Executive may serve on the board of directors of other
corporations with the prior approval of the Company's Board of Directors;

        (b) perform such services and assume such duties and responsibilities
which may from time to time be reasonably assigned to him by the Company's Board
of Directors, consistent with his office as Chief Executive Officer of Verisity-
Israel; and

        (c) in all respects use his best efforts to further, enhance and develop
Verisity-Israel's and the Company's business affairs, interests and welfare.

    3.  Compensation.  In consideration of Executive's services to the Company
        ------------
during the term of this Agreement, Executive will receive the following:

              (a) The Company will pay Executive a base salary equivalent to
$250,000 per annum during the remainder of 1998 and throughout 1999. Thereafter,
at the sole discretion of the Company's Board of Directors, Executive's base
salary may be increased (but shall not be required to increase) above the
$250,000 per annum level. Executive's base salary will be paid in equal
installments (pro rated for portions of a pay period) on the Company's regular
pay days and the Company will withhold from such compensation all applicable
federal and state income, social security, and disability and other taxes as
required by applicable laws.

              (b) Verisity-Israel will grant Executive an option to acquire up
to 671,938 of its ordinary shares pursuant to the Stock Option Agreement, a copy
of which is attached hereto as Exhibit A and Verisity-Israel's 1996 U.S. Stock
                               ---------
Option Plan ("Option Plan"), a copy of which is also included in Exhibit A.
                                                                 ---------

              (c) For each fiscal year of the Company during which Executive is
employed hereunder, commencing with the year beginning January 1, 1999,
Executive will be eligible for the award of an annual bonus, the criteria and
conditions of which will be established by the Company's Board of Directors
prior to the first day of such fiscal year, provided that at target levels the
amount of such bonus (the "Target Bonus") will be equal to fifty percent (50%)
of Executive's base salary payable during such year.

    4.  Appointment to the Board of Directors and Other Offices.  As soon as
        -------------------------------------------------------
practicable after the Effective Date of this Agreement:  the Company will take
all appropriate actions to cause Executive to be appointed or elected to its
Board of Directors and as the Company's Chairman; Verisity-Israel will take all
appropriate

                                      -2-
<PAGE>

actions to cause Executive to be appointed or elected to its Board of Directors
and to cause Executive to be appointed or elected as its Chief Executive
Officer.

    5.  Benefits and Reimbursements.
        ---------------------------

        5.1   Executive will, during the term hereof, have the right to receive
such benefits as are generally made available to full-time executive officers of
the Company.  In addition, or inclusive of such benefits, the Company will
provide Executive with the following:

              (a) the Company's standard medical and dental plan insurance
covering Executive and his immediate family;

              (b) in addition to normal holidays recognized by the Company,
Executive will be entitled to four weeks paid vacation annually, provided
however that any determination of amounts owed as accrued vacation upon
termination of employment will be based on Company's vacation policy then in
effect at the time of termination and based solely upon Executive's base salary,
as described in Section 3(a) above;

              (c) the Company reserves the right to modify, suspend or
discontinue any of the above benefit plans, policies and practices at any time
without notice to or recourse by Executive, so long as such action is taken
generally with respect to other similarly situated persons and does not single
out Executive.

        5.2   The Company will reimburse Executive for travel and other out-of-
pocket expenses reasonably incurred by Executive in the performance of his
duties hereunder, provided that all such expenses will be reimbursed only (i)
upon the presentation by Executive to the Company of such documentation as may
be reasonably necessary to substantiate that all such expenses were incurred in
the performance of his duties, and (ii) if such expenses are consistent with all
policies of the Company in effect from time to time as to the kind and amount of
such expenses.

    6.  Termination of Employment.
        -------------------------

        6.1   Termination At Will By Either Party.  Subject to the payment to
              -----------------------------------
Executive of the applicable severance payment as provided in Section 6.4(b)
below, if any, either party may terminate this Agreement, for any reason, with
or without Cause (as defined at Section 6.3 below), upon written notice to the
other.

                                      -3-
<PAGE>

     6.2  Death or Permanent Disability of Executive.  This Agreement will
          ------------------------------------------
terminate automatically upon the death or permanent disability of Executive.
Executive will be deemed permanently disabled for the purpose of this Agreement
if, in the good faith determination of the Board of Directors of the Company,
based on sound medical advice, Executive has become physically or mentally
incapable of performing his duties hereunder for a continuous period of 180
days, or for a total of 180 days in any consecutive 12-month period, in which
event Executive will be deemed permanently disabled upon the expiration of
either such 180-day period.  In the event of a termination of this Agreement due
to the death or permanent disability of Executive, Executive or his estate will
be entitled only to (i) the basic salary through the effective date of such
termination, in accordance with Section 3 above and (ii) a prorated portion of
the Target Bonus to the extent the same would have been earned by him had he
continued to be employed by the Company through the end of the fiscal year
during which his employment terminates as a result of such death or disability
(such proration to be based on the actual number of days of employment during
such year prior to the effective date of termination), but to no other severance
payment.

     6.3  Executive's Termination For Cause.  The Company will have the right to
          ---------------------------------
terminate Executive's employment hereunder for "Cause" at any time effective
upon its giving of notice to Executive of the facts and circumstances
constituting such Cause. For such purposes, "Cause" means the occurrence of one
or more of the following: (i) the commission by Executive of any act materially
detrimental to the Company or Verisity-Israel, including fraud, embezzlement,
theft, bad faith, gross negligence, dishonesty, recklessness or willful
misconduct; (ii) repeated failure or refusal to perform the lawful instructions
of, or duties as may be assigned to Executive by, the Company's Board of
Directors from time to time or as may be assigned to Executive as Chief
Executive Officer of Verisity-Israel by its Board of Directors; (iii) any state,
federal or other (e.g., foreign) conviction, including but not limited to a plea
of nolo contendere to a felony charge; (iv) any material misrepresentation by
Executive to the Company or Verisity-Israel regarding the operation or status of
the Company or Verisity-Israel or any material aspect of their business; (v) any
disclosure by Executive of any material confidential information; (vi) any
violation by Executive of any of Company's policies, practices or procedures; or
(vii) breach of any covenant of this Agreement.

     6.4  Compensation Upon Termination.
          -----------------------------

          (a)  In the event that the Company terminates Executive's employment
for "Cause" pursuant to Section 6.3 above, Executive will be entitled to only:
(i) the compensation provided for in Section 3(a) above for the period of

                                      -4-
<PAGE>

time ending with the date of termination; (ii) compensation for any unused
vacation that Executive may have accrued, as well as all earned benefits, up to
and including the date of termination; (iii) "COBRA" benefits to the extent
required by applicable law; and (iv) reimbursement for such expenses as
Executive may have properly incurred on behalf of the Company as provided in
Section 5.2 above prior to the date of termination.

          (b)  In the event that either (i) the Company (or any "Successor
Entity" as that term is defined in the Option Plan) terminates Executive's
employment without "Cause" pursuant to Section 6.3 above, or (ii) Executive
voluntarily terminates his employment with the Company following any
Constructive Termination Event (as defined below), then in addition to the
amounts payable pursuant to Section 6.4(a) above, Executive will be entitled to
receive (i) payments earned pursuant to Section 3(c) above prior to his
termination and (ii) a severance payment in an amount equal to the sum of the
aggregate base salary and the amount of the Target Bonus whether or not such
Target Bonus would have otherwise been payable to Executive by the Company
pursuant to Section 3(c) above for (A) the 6-month period following the
effective date of any such termination occurring prior to the first anniversary
of the Effective Date, except a termination occurring during the 12-month period
following the Closing of a Change of Control Transaction (as those terms are
defined in the Option Plan), or (B) the 12-month period following the effective
date of such termination occurring on or after the first anniversary of the
Effective Date or the 12-month period following the Closing of a Change of
Control Transaction, provided that in any case the Company's obligation to pay
any severance payment to Executive will be expressly conditioned upon the
execution by Executive and delivery by him to the Company and Verisity-Israel of
a general release and waiver of all claims (employment-related and otherwise)
against the Company, Verisity-Israel and their affiliates as well as their
respective officers, directors, employees and agents, and covenant not to sue
any such party in connection with such released claims, in reasonable form
provided by the Company. For purposes hereof, the term "Constructive Termination
Event" means and includes: (i) any notice or decision by the Board of Directors
of Verisity-Israel (or, in the event of a Change of Control Transaction, of any
Successor Entity) that Executive will no longer serve in the capacity of Chief
Executive Officer of Verisity-Israel (or Chief Executive Officer of such
Successor Entity); (ii) any notice or decision by the Board of Directors of the
Company (or any Successor Entity) that Executive will no longer serve in the
capacity of Chairman of the Company (or such Successor Entity); or (iii) any
relocation of the Company's principal executive offices, or of Executive's place
of employment, to a location outside of either Santa Clara County, San Mateo
County, the City and County of San Francisco, Marin County,

                                      -5-
<PAGE>

Sonoma County, Napa County, Solano County, Contra Costa County or Alameda
County.

          (c)  The payments set forth in this Section 6.4 will fully discharge
all responsibilities of the Company and Verisity-Israel to Executive under this
Agreement, or relating to or arising out of the termination of Executive's
employment.

     6.5  Limitation on Payments.  In the event that the severance and other
          ----------------------
benefits provided to Executive under this Section 6 ("Severance Payments") would
(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 6, such Severance Payments (together with any other "parachute payments"
made to the Executive hereunder or under any other agreement with the Executive)
would be subject to the excise tax imposed by Section 4999 of the Code, then
such Severance Payments under this Section 6 shall be either:

          (a)  payable in full, reduced only by the tax cost, if any, to the
Company as a result of any loss of any deduction under Section 280G of the Code
with respect to the Severance Payment; or

          (b)  payable in such lesser amount which would result in no portion of
such Severance Payments 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 Executive on an after-tax basis, of the greatest
amount of payments under this Section 6.  Unless the Company and Executive
otherwise agree in writing, any determination required under this Section 6.5
shall be made in writing by independent public accountants agreed to by the
Company and Executive (the "Accountants"), whose determination shall be
conclusive and binding upon Executive and the Company for all purposes.  For
purposes of making the calculations required by this Section 6.5, the
Accountants may make reasonable assumptions and approximations concerning
applicable taxes (of both the Executive and the Company) and may rely on
reasonable, good faith interpretations concerning the application of Sections
280G and 4999 of the Code.  The Company and 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 6.5.  The Company
and the Executive will equally share all costs the Accountants may reasonably
incur in connection with any calculations contemplated by this Section 6.  As
long as the Company has not registered any of its securities under the
Securities Act of 1933, as amended, and is not required to file any reports
under the Securities Exchange Act

                                      -6-
<PAGE>

of 1934, as amended, it will use its best efforts to seek shareholder approval
of the Severance Payments to be made to Executive hereunder.

     7.   Unfair Competition By Executive.
          -------------------------------

          7.1  Executive agrees that all trade secrets, confidential or
proprietary information with respect to the activities and businesses of the
Company and Verisity-Israel, including, without limitation, personnel
information, secret processes, know-how, customer lists, data bases, ideas,
techniques, processes, inventions (whether patentable or not) and other
technical plans, business plans, marketing plans, product plans, forecasts,
contacts, strategies and information (collectively "Proprietary information")
which were learned by Executive in the course of his employment by the Company
or his services to Verisity-Israel, and any other Proprietary Information
received, developed or learned by Executive hereafter in the course of his
future employment by or in association with the Company and Verisity-Israel are
confidential and will be kept and held in confidence and trust as a fiduciary by
Executive.  Executive will not use or disclose Proprietary Information except as
necessary in the normal course of the business of the Company or Verisity-Israel
for their sole and exclusive benefit, unless Executive is compelled so to
disclose under process of law, in which case Executive will first notify the
Company promptly after receipt of a demand to so disclose.  Upon termination of
Executive's employment with the Company for any reason, he will immediately
deliver to the Company all tangible, written, graphical, machine readable and
other materials (including all copies) in his possession or under his control
containing or disclosing Proprietary Information.  Executive will not disclose
to the Company or Verisity-Israel, or use in connection with his employment on
behalf of the Company or Verisity-Israel, any confidential information of any
third party.  Executive represents to the Company and Verisity-Israel that his
employment with the Company, and his activities on its behalf and on behalf of
Verisity-Israel, will not violate any obligation or commitment that Executive
has to any third party.

          7.2  For a period of two (2) years following the termination of his
employment with the Company for any reason, he will not, without the Company's
express written consent, either on his own behalf or on behalf of another,
solicit employees of the Company or Verisity-Israel for the purpose of hiring
them.

          7.3  Executive, the Company and Verisity-Israel acknowledge that: (i)
each covenant and restriction contained in Sections 7.1, 7.2 and 8 of this
Agreement is necessary, fundamental and required for the protection of the
Company's and Verisity-Israel's business; (ii) such relate to matters which are
of a

                                      -7-
<PAGE>

special, unique and extraordinary character that gives each of them a special,
unique and extraordinary value; and (iii) a breach of any such covenant or
restriction will result in irreparable harm and damage to the Company and/or
Verisity-Israel which cannot be compensated adequately by a monetary award.
Accordingly, it is expressly agreed that, in addition to all other remedies
available at law or in equity, and notwithstanding anything to the contrary in
Section 10 below, the Company and/or Verisity-Israel will be entitled to the
immediate remedy of a temporary restraining order, preliminary injunction or
such other form of injunctive or equitable relief as may be used by any court of
competent jurisdiction to restrain or enjoin any of the parties hereto from
breaching any such covenant or restriction, or otherwise specifically to enforce
the provisions contained in Sections 7.1, 7.2 and 8 of this Agreement.

     8.   PROPRIETARY MATTERS.  Executive expressly understands and agrees that
          -------------------
any and all improvements, inventions, discoveries, processes or know-how that
are generated or conceived by Executive during the term of this Agreement,
whether so generated or conceived during Executive's regular working hours or
otherwise, will be the sole and exclusive property of the Company, and Executive
will, whenever requested to do so by the Company (either during the term of this
Agreement or thereafter), execute and assign any and all applications,
assignments and/or other instruments and do all things which the Company may
deem necessary or appropriate lit order to apply for, obtain, maintain, enforce
and defend patents, copyrights, trade names or trademarks of the United States
or of foreign countries for said improvements, inventions, discoveries,
processes or know-how, or in order to assign and convey or otherwise make
available to the Company the sole and exclusive right, title and interest in and
to said improvements, inventions, discoveries, processes, know-how,
applications, patents, copyrights, trade names or trademarks, subject to
California Labor Code section 2870, which reads as follows:

          "(a) Any provision in an employment agreement which
     provides that an employee shall assign, or offer to assign,
     any of his or her rights in an invention to his or her
     employer shall not apply to an invention that the employee
     developed entirely on his or her own time without using the
     employer's equipment, supplies, facilities or trade secret
     information except for those inventions that either:

               (1) Relate at the time of conception or reduction
     to practice of the invention to the employer's business, or
     actual or demonstrably anticipated research or development
     of the employer; or

                                      -8-
<PAGE>

               (2) Result from any work performed by the employee
          for the employer.

          (b)  To the extent a provision in an employment
     agreement purports to require an employee to assign an
     invention otherwise excluded from being required to be
     assigned under subdivision (a), the provision is against the
     public policy of this state and is unenforceable."

     9.   KEY-MAN INSURANCE.  Executive agrees to make himself available and to
          -----------------
undergo, at the Company's request and expense, any physical examination or other
procedure necessary to allow the Company to obtain a key-man insurance policy on
Executive.  If the Company obtains such policy, it will maintain the policy at
its expense and all proceeds will be the sole property of the Company.

     10.  ARBITRATION.  The parties will attempt in good faith promptly by
          -----------
negotiations to resolve any dispute or controversy arising out of or relating to
this Agreement or to the employment or termination of Executive by the Company.
If a party intends to be accompanied at a negotiation meeting by an attorney,
the other party will be given at least three working days' notice of such
intention and may also be accompanied by an attorney.  All negotiations pursuant
to this clause are confidential and will be treated as compromise and settlement
negotiations for purposes of the Federal Rules of Evidence and state rules of
evidence.

          In the event the parties are unable to settle such controversy
amicably through negotiations, the dispute will be submitted to binding
arbitration before a single arbitrator in accordance with the Employment Dispute
Resolution Rules of the American Arbitration Association provided that: (i) the
arbitrator will be instructed and empowered to take whatever steps to expedite
the arbitration as he or she deems reasonable; (ii) each party will bear its own
costs in connection with the arbitration; (iii) the arbitrator's judgment will
be final and binding upon the parties, except that it may be challenged on the
grounds of fraud or gross misconduct; and (iv) the arbitration will be held in
Santa Clara County, California. Judgment upon any verdict in arbitration may be
entered in any court of competent jurisdiction. The parties hereby consent to
the jurisdiction of, and proper venue in, the federal and state courts located
in Santa Clara County, California.

          Unless otherwise expressly set forth in this Agreement, the procedures
specified in this Section 10 will be the sole and exclusive procedures for the
resolution of disputes and controversies between the parties arising out of or
relating to this Agreement; provided, however, that a party may seek a
preliminary injunction or other provisional judicial relief, if in its judgment
such action is necessary to avoid irreparable damage or to preserve the status
quo.  Despite such

                                      -9-
<PAGE>

action the parties will continue to participate in good faith in the procedures
specified in this Section 10.

                            SECURED PROMISSORY NOTE

 $201,581.40                                                    March 23, 1998

     FOR VALUE RECEIVED, the undersigned, Moshe Gavrielov ("Purchaser") hereby
promises to pay Verisity Design, Inc., a California corporation ("Verisity-
California") or order (the "Holder"), at its principal offices, or such other
place as the Holder may direct, on the date (the "Maturity Date") which is the
earlier of (1) March 23, 2002, or (2) sixty days after the termination of
Purchaser's employment with Verisity-California, the principal sum of TWO
HUNDRED AND ONE THOUSAND FIVE HUNDRED EIGHTY-ONE and 40/100 Dollars
($201,581.40), with interest from the date of this Promissory Note, payable
annually on the unpaid principal sum from time to time outstanding, in lawful
money of the United States, at the lesser of (i) the relevant mid-term
applicable federal rate in effect as of the date of this Promissory Note as
published by the Internal Revenue Service (i.e. 5.59% per annum), or (ii) the
maximum rate permitted under applicable law.

     This Note is executed and delivered together with a Pledge Agreement
between Purchaser and the Holder by which Purchaser has pledged to Holder, among
other things, his right, title, and interest in and to SIX HUNDRED SEVENTY-ONE
THOUSAND NINE HUNDRED THIRTY-EIGHT (671,938) ordinary shares ("Shares") of
Verisity Ltd., a company organized under the laws of the State of Israel and the
sole shareholder of Verisity-California, such shares having been purchased with
the cash proceeds of a loan from Verisity-California to Purchaser which is
evidenced by this Note. In addition to the security interest created under the
Pledge Agreement, this Note is intended to evidence a full recourse obligation
of Purchaser.

     This Note may be prepaid by Purchaser in whole or in part, at any time or
from time to time, without penalty or premium. Purchaser may pay any principal
outstanding on this Note by conveying to Verisity-California any Shares then
owned by him that are "Vested" within the meaning of the Share Restriction
Agreement between Purchaser and Verisity Ltd., by means of delivery of a
transfer deed to Verisity-California with respect to such Shares, with the
amount of such payment being equal to the Fair Market Value of such Shares, the
determination of which will be in the manner set forth in the 1996 U.S. Stock
Option Plan of Verisity Ltd.

     Purchaser waives diligence, presentment, demand, protest, and notice of
protest, dishonor, and nonpayment.

     If any action or proceeding is brought by the Holder to enforce payment of
this Note, then the prevailing party shall be entitled to recover reasonable
attorneys' fees and other costs incurred therein.

     This Note is to be construed in accordance with and be governed by the laws
of the State of California applicable to contracts made and to be performed in
the State of California.
