Dear Christopher,

On behalf of Genesys Telecommunications Laboratories, Inc. (the "Company"), I am
pleased to offer employment with the Company on the following terms:

1.  You will be employed as the Chief Financial Officer and Sr. Vice President
    of Finance and Administration reporting to the CEO, with an anticipated
    start date of April 8, 1999. This offer and your employment is contingent
    upon:

    A. Satisfactory results of background and reference checks.
    B. Receipt, within three days of employment, of proof, provided by you, of
       your legal right to work in the United States
    C. Receipt of an executed copy of the Company's form of confidential
       information and invention assignment agreement (which is attached)
    D. Your agreement to devote, during your employment, your full time efforts
       to your responsibilities at the Company and not to engage in any other
       activities which would conflict with the best interests of the Company.

2.  Your base compensation will be $300,000 annualized salary ("Base Salary"),
    plus commission/bonus of 40% of Base Salary at target and 80% of Base Salary
    at maximum in accordance with the Company's bonus plan.

    We will propose to the Board that you be granted two (2) options to purchase
    shares of the Company's Common Stock under the Company's 1997 Stock
    Incentive Plan at a purchase price equal to the fair market value of such
    shares on the date the options are approved by the Board. The first option
    will be for 300,000 shares and will vest over a period of four years
    beginning with your date of employment, at a rate of 25% of the shares at
    the end of the first year and 1/48th of the shares at the end of each month
    thereafter. The second option will be for 50,000 shares and will vest
    immediately.

    The first option, referred to above, will provide for certain acceleration
    upon a constructive termination in the event of a change of control, the
    conditions of which are outlined in Schedule A to this offer letter, and
    upon a "Not for Cause Termination", the conditions of which are outlined in
    Article 4,b,(ii) below.

3.  You will be eligible to participate in the company's standard package of
    employee benefits, which includes medical, dental, life and disability
    insurance, a flexible spending program, and Employee Stock Purchase Plan
    (ESPP), and 401(k) plan.

4.  At all times, your employment with the Company is "at-will", which means
    that employment with the Company may be terminated at any time by either you
    or the Company with or without cause or justification, subject only to the
    entitlements, liabilities and obligations set forth in 4(a)-(c), below; and
    upon any termination of your employment, you agree to immediately resign as
    an officer of the Company. The at-will nature of this employment
    relationship shall not change.

    (a) Termination for Cause.
        ----------------------

        (i)  In the event that Company terminates your employment for "cause,"
             Company's total liability under this Agreement shall be that
             described in 4(b)(i) below. "Cause" shall mean:

             (1) gross negligence or your repeated failure to perform your
                 duties and responsibilities to the reasonable satisfaction of
                 the CEO, President, or any other appropriate officer or any
                 breach by you of your fiduciary duties to the Company. For
                 purposes of this letter, any act or acts or omission or
                 omissions known by or within the control of the employee that
                 have a material adverse effect on the Company's operations or
                 business shall be deemed to be a breach of your duties and
                 responsibilities to the Company; or

             (2) the commission of any criminal acts, act of fraud, embezzlement
                 or actual dishonesty by you, any unauthorized use or disclosure
                 by you of confidential information or trade secrets of Company
                 (or any Parent or Subsidiary).

        (ii) In the event that Company terminates your employment other than for
             "Cause," Company's total liability under this Agreement shall be
             that described in 4(b)(ii) below.

    (b) Entitlements and Liabilities Upon Termination. Your entitlements and the
        ---------------------------------------------
        Company's liabilities upon any termination of your employment shall be
        one of the following, depending upon circumstances of the termination,
        as specified in 4(a) above; and you shall not be entitled to any further
        compensation, any benefits or stock vesting except as specified below:

        (i)  In the event of termination for cause, you shall be entitled to,
             and Company shall pay to you, your Base Salary earned through the
             date of termination, and your participation in all employee
             benefits shall cease as of the date of termination except as you
             may be eligible and elect to continue pursuant to COBRA.

        (ii) In the event of termination by Company other than for cause, and
             provided that during the period after termination for which Company
             is obligated to pay you, you comply with obligations of 4(c) below,
             you shall be entitled to and Company shall continue to pay you,
             your Base Salary, bonus at target and COBRA continuation premiums
             for twelve (12) months after the date of termination. In addition,
             upon a not for cause termination, the total acceleration of options
             shall be equal to 50% of the remaining unvested options, at the
             time of the termination, as if the original two grants were based
             upon the four year vesting schedule.

    (c) Your Obligations.
        ----------------

        (i)  As a condition of receiving any severance payments under this
             Section 4, above, you shall be required to execute in favor of the
             Company and deliver a waiver and general release of any and all
             claims, known and unknown, in such form as the President or any
             designee shall specify.

             obligated to make, any payment to you pursuant to 4(b) above, you
             shall hold yourself available to consult with Company in a manner
             requested by the CEO, President or any designee and shall not
             (without limiting any other obligations you may have to the
             Company):

             (1) own, engage in, have any substantial interest in, advise or
                 provide any services or labor to any person or entity engaged
                 in any business that is in any material way directly
                 competitive with the business that is conducted by Company; or

             (2) solicit, accept or receive any compensation from any person or
                 entity engaged in any business that is in any material way
                 directly competitive with the business that is conducted by
                 Company; or

             (3) contact, solicit or call upon any customer or supplier of
                 Company on behalf of any person or entity other than Company
                 for the purpose of selling, providing or performing any
                 products or services directly competitive with those provided
                 or performed by Company; or

             (4) induce or attempt to induce any person or entity to curtail or
                 cancel any business or contracts which such person or entity
                 has or is in the process of having with Company; or

             (5) induce or attempt to induce any person or entity to terminate,
                 cancel or breach any contract which such person or entity has
                 with Company, to terminate any person's employment relationship
                 with Company, or to receive or accept any benefits in the event
                 of such termination, cancellation or breach.

             You agree to enter into such additional documents or agreements
             reflecting the foregoing Section as the Company may reasonably
             request.

5.  You represent and warrant that you are not breaching any contractual
    relationship or obligation toward any other person or entity by entering
    into an employment relationship with the Company, by executing this
    Agreement or by complying with the terms and conditions of the same.
    Furthermore, you understand that Company is hiring you solely for the
    purpose of engaging your skill and expertise, and not to acquire any trade
    secret, proprietary or confidential information belonging to any other
    person or entity; and that in performing under this Agreement, you are
    prohibited by Company from disclosing any such trade secret and proprietary
    or confidential information to Company.

6.  Dispute Resolution; Arbitration in Lieu of Civil Litigation.

    (a) You and the Company (hereafter "the Parties") hereby agree that any and
        all controversies, claims or disputes that Company may have with you or
        that you may have with Company, or any of its employees, officers,
        directors, agents or assigns, which arise out of your employment with
        Company, shall be resolved through final and binding arbitration in
        accordance with National Rules for the Resolution of Employment Disputes
        of the American Arbitration Association. The arbitration shall be
        conducted in San Francisco, California before a single arbitrator
        mutually agreed by Company and you; provided that if they are unable to
        agree on a single arbitrator within 30 days of the demand by either
        party for arbitration, an arbitrator shall be designated by the San
        Francisco Office of the American Arbitration Association.

    (b) Such controversies, claims and disputes include, without limitation, any
        controversy, claim or dispute relating to your employment or the
        termination thereof, claims for breach of contract or breach of the
        covenant of good faith and fair dealing, infliction of emotional
        distress, defamation and any claims of discrimination, harassment or
        other claims under the California Fair Employment and Housing Act, Title
        VII of the Civil Rights Act of 1964, the Age Discrimination in
        Employment Act, the Americans With Disabilities Act, the Employee
        Retirement Income Securities Act, the Family Care and Medical leave Act,
        and any other federal, state or local law or regulation now in existence
        or hereinafter enacted and as amended from time to time regarding
        employment, termination of employment and the terms and conditions of
        employment, including the California Labor Code.

    (c) The only controversies, claims or disputes not covered by this covenant
        to arbitrate, are those regarding your entitlement to benefits under the
        unemployment insurance or workers' compensation laws.

    (d) The Parties will share equally the cost of the arbitration filing and
        hearing fees and the cost of the arbitrator. Each party will bear its
        own attorneys' fees and the arbitrator will not have the authority to
        award attorney's fees unless a statutory section at issue in the dispute
        authorizes the award of attorneys' fees to the prevailing party, in
        which case the arbitrator shall have the authority to make such award as
        permitted by the statute in question.

    (e) The Parties understand and agree that arbitration shall be instead of
        any civil litigation. This means that each party is waiving any right to
        a jury trail, and that the arbitrator's decision shall be final and
        binding to the fullest extent permitted by law and enforceable by any
        court having jurisdiction thereof.

7.  This Agreement reflects the full and complete understanding and agreement
    between you and the Company regarding your employment relationship with the
    Company, and it shall supersede any and all prior written or oral
    negotiation, offer or agreement regarding your employment relationship with
    the Company.

To indicate your acceptance of the Company's offer, please sign and date this
letter in the space provided below and return it to me.  This offer will remain
in effect for 5 calendar days from the date of this letter.  A duplicate
original is enclosed for your records.

Chris, we very much look forward to working with you.

Very truly yours,

/s/ Ori Sasson
