merged with and into the Company, the separate corporate existence of Merger Sub
shall cease and the Company shall continue as the surviving corporation and as a
wholly-owned subsidiary of Parent.  The Company as the surviving corporation
after the Merger is hereinafter sometimes referred to as the "Surviving
                                                              ---------

  1.2     Effective Time.  Unless this Agreement is earlier terminated pursuant
          --------------                                                       
to Section 7.1, the closing of the Merger (the "Closing") will take place as

  1.3     Effect of the Merger.  At the Effective Time, the effect of the Merger
          --------------------                                                  
shall be as provided in the applicable provisions of Delaware Law.  Without

Time, all the property, rights, privileges, powers and franchises of the Company
and Merger Sub shall vest in the Surviving Corporation, and all debts,
liabilities and duties of the Company and Merger Sub shall become the debts,
liabilities and duties of the Surviving Corporation.

  1.4     Certificate of Incorporation.  Unless otherwise determined by Parent
          ----------------------------

following the Effective Time shall be Ori Sasson, Gregory Shenkman and Alec
Milisloavsky and the officers of the Surviving Corporation shall be the officers
of Merger Sub immediately prior to the Effective Time, each to hold office in
accordance with the Certificate of Incorporation and Bylaws of the Surviving
Corporation.

  1.6     Shares to Be Issued; Effect on Common Stock.  The number of Parent
          -------------------------------------------                       
Common Shares to be issued pursuant to the Merger in exchange for (i) the
acquisition by Parent of all outstanding Company Common Stock and (ii) the
assumption by Parent of all outstanding options to acquire Company Common Stock
(collectively "Company Options") shall be 250,000 shares (the "Aggregate Parent
               ---------------                                 ----------------
Shares"). Subject to the terms and conditions of this Agreement, as 
- ------                                                                    

                                      -2-

 
of the Effective Time, by virtue of the Merger and without any action on the
part of Merger Sub, the Company or the holder of any shares of the Company
Common Stock, the following shall occur:

           (a)   Company Common Stock.  Pursuant to the Merger, each share of 
                 --------------------       
Company Common Stock issued and outstanding immediately prior to the Effective
Time will be automatically assigned and transferred to Parent at the Effective
Time, without any further action required on the part of the Company, the
shareholders of the Company or Parent. In exchange for each such share of
Company Common Stock the holder thereof shall be entitled to receive a number
of Parent Common Shares equal to the Exchange Ratio (as defined in
subparagraph (f) below).

           (b)   Company Options.  At the Effective Time, each Company Option 
                 ---------------            
shall be assumed by Parent in accordance with provisions described below.

                 (i)   At the Effective Time, each Company Option, whether or
not vested and exercisable, shall be, in connection with the Merger, canceled
and in substitution therefor Parent shall issue a new option (a "Parent
                                                                 ------
Option"). Each Parent Option shall continue to be subject to the same terms
- ------
and conditions as the respective Company Option, including vesting, except
that (A) each Parent Option shall be exercisable for that number of whole
shares of Parent Common Shares equal to the product of (1) the number of
shares of Company Common Stock (on an as converted into Common Stock basis)
that were issuable upon exercise of such Company Option immediately prior to
the Effective Time multiplied by (2) the Exchange Ratio (rounded up to the
nearest whole number of Parent Common Shares), and (B) the exercise price per
share of Parent Common Shares under such Parent Option shall be equal to the
quotient determined by dividing (1) the exercise price per share of Company
Common Stock at which such Company Option was exercisable immediately prior to
the Effective Time (on an as converted into Common Stock basis), by (2) the
Exchange Ratio (rounded down to the nearest whole cent).

                 (ii)  As promptly as practicable following the Effective
Time, Parent will issue, to each holder of an outstanding Company Option
immediately prior to the Effective Time, a new Parent Option in respect of the
canceled Company Option. In this regard, it is the intention of the parties
that if any Company Option qualified upon its grant as an incentive stock
option as defined in Section 422 of the U.S. Internal Revenue Code, then the
corresponding Parent Option issued by Parent in respect of such Company Option
also qualify following the Effective Time as an incentive stock option.

           (c)   Capital Stock of Merger Sub.  Pursuant to the Merger, each 
                 ---------------------------     
share of Common Stock of Merger Sub issued and outstanding immediately prior

the Escrow Amount contributed on behalf of each holder of Company Common Stock
shall be in proportion to the aggregate number of Parent Common Shares which
such holder would otherwise be entitled to receive under Section 1.6 by virtue

had no operations prior to the acquisition, through Plato Israel, of all of the
assets and certain of the liabilities of AgentSoft, Ltd. on September 14, 1998.
The Company has not prepared a statement of operations.  The Company has had no
revenues since inception, and its aggregate losses (and accumulated deficit)

as of its date, it being noted, however, that the Balance Sheet has not been
prepared in accordance with generally accepted accounting principles.  The
Company represents that it does not have any liability, indebtedness,
obligation, expense, claim, deficiency, guaranty or endorsement of any type
which would be required to be reflected on a balance sheet in accordance with
generally accepted accounting principles (a "Liability"), that is not reflected
                                             ---------

knowledge, the Company has complied in all material respects with all applicable

then ended (subject, in the case of unaudited statements, to normal, recurring
audit adjustments which will not be material in amount or significance).  There
has been no change in Parent accounting policies except as described in the
notes to the Parent Financial Statements.

     3.6   No Conflict.  Neither the execution and delivery of this Agreement by
           -----------           
Parent, nor the consummation by Parent of the transactions contemplated hereby,
nor compliance by Parent with any of the provisions hereof, will (i) conflict
with or result in a breach of any provision of Parent's Articles of
Incorporation, (ii) constitute or result in a default under, or require any
consent pursuant to, or result in the creation of any lien on any material asset
of any Parent under, any contract or permit of Parent, where such default or
lien, or any failure to obtain such 

                                      -11-

 
consent, is reasonably likely to have, individually or in the aggregate, a
material adverse effect on Parent and its subsidiaries, taken as a whole or
(iii) subject to receipt of the requisite consents referred to in Section 3.6,
constitute or result in a default under, or require any consent pursuant to, any
law or order applicable to Parent or any of its respective material assets.

than consents required from regulatory authorities, no notice to, filing with,
or consent of, any public body or authority is necessary for the consummation by
Parent of the Merger and the other transactions contemplated in this Agreement.

incurred by a director or officer of the Company entitled to indemnification

           ------------------------------------------     
representations and warranties in this Agreement or in any instrument delivered
pursuant to this Agreement (each as modified by the Company Schedules) shall
survive the Merger and continue until 5:00 p.m. California  time, on May 31,
1999 (the "Expiration Date").
           ---------------   

     6.2   Escrow Arrangements.
           -------------------

           (a)   Escrow Fund.  At the Effective Time the Company's shareholders
                 -----------    
will be deemed to have received and consented to the deposit with the Escrow
Agent (as defined below) of the Escrow Amount (plus any additional shares as may
be issued upon any stock split, stock dividend or recapitalization effected by
Parent after the Effective Time) pursuant to an Escrow Agreement on customary
terms to be mutually agreed among Parent, the Company and the Escrow Agent (as
defined below), without any act required on the part of any shareholder. As soon
as practicable after the Effective Time, the Escrow Amount, without any act
required on the part of any shareholder, will be deposited with an escrow agent
acceptable to Parent and the Securityholder Agent (as defined in Section
6.2(i)(i) below) as Escrow Agent (the "Escrow Agent"), such deposit to
                                       ------------                   
constitute an escrow fund (the "Escrow Fund") to be governed by the terms set
                                -----------                                  
forth herein and at Parent's cost and expense.  The portion of the Escrow Amount
contributed on behalf of each shareholder of the Company shall be in proportion
to the aggregate Parent Common Shares which such holder would otherwise be
entitled under Section 1.6.  The Escrow Amount shall be contributed entirely out
of the shares of Parent Common Shares issuable upon the Merger in respect of
Company Common Stock.  The Escrow Fund shall be available to compensate Parent
and its affiliates for any claims, losses, liabilities, damages, deficiencies,
costs and expenses, including reasonable attorneys' fees and expenses, and
expenses of investigation and defense (hereinafter individually a "Loss" and
                                                                   ----     
collectively "Losses") incurred by Parent, its officers, directors, or
              ------                                                  
affiliates (including the Surviving Corporation) directly or indirectly as a
result of any inaccuracy or breach of a representation or warranty of the
Company contained in Article II herein (as modified by the Company 

                                      -17-

 
Schedules), or any failure by the Company to perform or comply with any covenant
contained herein. Parent and the Company each acknowledge that such Losses, if
any, would relate to unasserted contingent liabilities existing at the Effective
Time, which if resolved at the Effective Time would have led to a reduction in
the aggregate Merger consideration. Parent may not receive any shares from the
Escrow Fund unless and until Officer's Certificates (as defined in paragraph (e)
below) identifying Losses, the aggregate amount of which exceed $100,000, have
been delivered to the Escrow Agent as provided in paragraph (f). In such case,
Parent may recover from the Escrow Fund its Losses in excess of the first
$100,000.

           (b)   Limitation on Amount of Loss.  The amount of recovery 
                 ----------------------------   
available to Parent and its affiliates for any Loss hereunder shall be reduced
by any insurance proceeds received as a result of any such Loss.

           (c)   Exclusive Remedy.  Claims against the Escrow Fund pursuant to 
                 ----------------            
this Article VI shall comprise the sole and exclusive means of recourse
available to Parent, Merger Sub and any of their respective affiliates,
successors and assigns (collectively, "ParentGroup") in respect of any breach
                        -----------                                             
or alleged breach by the Company or any of its agents of any representation,
warranty or covenant contained in this Agreement, and in respect of any other
claim, damage or liability as to which ParentGroup may seek recovery or
recourse in connection with the transactions contemplated by this Agreement.

           (d)   Escrow Period; Distribution upon Termination of Escrow 
                 ------------------------------------------------------- 
Periods.  Subject to the following requirements, the Escrow Fund shall be in 
- ------- 
existence immediately following the Effective Time and shall terminate on the
Expiration Date (the "Escrow Period"); provided that the Escrow Period shall
                      --------------        
not terminate with respect to such amount (or some portion thereof), that
together with the aggregate amount remaining in the Escrow Fund is necessary
to satisfy any unsatisfied claims concerning facts and circumstances existing
prior to the termination of such Escrow Period and to the extent specified in
any Officer's Certificate delivered to the Escrow Agent prior to termination
of such Escrow Period. As soon as all such claims have been resolved, the
Escrow Agent shall transfer to the shareholders of the Company, pursuant to
written instructions by Parent, the remaining portion of the Escrow Fund not
required to satisfy such claims subject to the restriction that, if any of the
shares in escrow are subject to a repurchase right in favor of the Company,
upon termination of services to the Company, then such shares shall not be
distributed to the shareholder but in lieu thereof shall (to the extent not
already repurchased in the event of prior termination of services) be
delivered to the appropriate escrow agent who is authorized to hold such
shares for the benefit of the Company in the event of a future termination of
services to the Company. Unless and until the Escrow Agent shall have received
from Parent written notice that some or all of the Escrow Shares are subject
to a repurchase right in favor of the Company, the Escrow Agent may assume
without inquiry that no repurchase rights exist. Deliveries of Escrow Amounts
to the shareholders of the Company pursuant to this Section 6.2(d) shall be
made in proportion to their respective original contributions to the Escrow
Fund.

           (e)   Protection of Escrow Fund.
                 ------------------------- 

                                      -18-

 
                 (i)    The Escrow Agent shall hold and safeguard the Escrow
Fund during the Escrow Period, shall treat such fund as a trust fund in
accordance with the terms of this Agreement and not as the property of Parent
and shall hold and dispose of the Escrow Fund only in accordance with the
terms hereof.

                 (ii)   Any shares of Parent Common Shares or other equity
securities and any cash dividends issued or distributed by Parent (including
shares issued upon a stock split) ("New Shares") in respect of Parent Common
                                    ----------  
Shares in the Escrow Fund which have not been released from the Escrow Fund as
of the time of such issuance or distribution by Parent shall be deemed
distributed to and received by the shareholders but such shareholders have
consented that such New Shares and cash dividends shall be added to the Escrow
Fund and become a part thereof. New Shares and cash dividends issued in
respect of shares of Parent Common Shares which have been released from the
Escrow Fund as of the time of such issuance or distribution by Parent shall
not be added to the Escrow Fund but shall be distributed to the recordholders
thereof.

                 (iii)  Each shareholder shall be entitled to control the vote
of the shares of Parent Common Shares contributed to the Escrow Fund by such
shareholder (and on any voting securities added to the Escrow Fund in respect
of such shares of Parent Common Shares), and the Escrow Agent in whose name
the shares are held shall vote such shares on all matters as instructed in
writing by the Securityholder Agent.

           (f)   Claims Upon Escrow Fund.
                 ----------------------- 

                 (i)    Upon receipt by the Escrow Agent at any time on or
before the last day of the Escrow Period of a certificate signed by any
officer of Parent (an "Officer's Certificate"): (A) stating that Parent has
                       ---------------------   
paid or properly accrued or reasonably anticipates that it will have to pay or
accrue Losses, and (B) specifying in reasonable detail the individual items of
Losses included in the amount so stated, the date each such item was paid or
properly accrued, or the basis for such anticipated liability, and the nature
of the misrepresentation, breach of warranty or covenant to which such item is
related, the Escrow Agent shall, subject to the provisions of Section 6.2(g)
hereof, cause the transfer agent of Parent Company Shares to transfer to
Parent out of the Escrow Fund, as promptly as practicable, Parent Common
Shares held in the Escrow Fund in an amount having a value equal to such
Losses.

                 (ii)   For the purposes of determining the number of shares
of Parent Common Shares to be delivered to Parent out of the Escrow Fund
pursuant to Section 6.2(f)(i) hereof, the shares of Parent Common Shares shall
be valued at the average closing price of Parent's Common Stock for the ten
(10) consecutive trading days ending on the trading day immediately prior to
the Closing Date, as reported on the Nasdaq National Market. Parent and the
Securityholder Agent shall certify such fair market value in a certificate
signed by both Parent and the Securityholder Agent, and shall deliver such
certificate to the Escrow Agent, who may rely on it without inquiry.

           (g)   Objections to Claims.  At the time of delivery of any Officer's
                 --------------------  
Certificate to the Escrow Agent, a duplicate copy of such certificate shall be
delivered to the Securityholder 

                                      -19-

 
Agent and for a period of thirty (30) days after receipt of an Officer's
Certificate by the Escrow Agent, the Escrow Agent shall make no transfer to
Parent of any Escrow Amounts pursuant to Section 6.2(f) hereof unless the
Escrow Agent shall have received written authorization from the Securityholder
Agent to make such transfer. After the expiration of such thirty (30) day
period, the Escrow Agent shall cause the transfer agent of Parent Company
Stock to transfer shares of Parent Common Shares from the Escrow Fund in
accordance with Section 6.2(f) hereof, provided that no such transfer may be
made if the Securityholder Agent shall object in a written statement to the
claim made in the Officer's Certificate, and such statement shall have been
delivered to the Escrow Agent prior to the expiration of such thirty (30) day
period.

           (h)   Resolution of Conflicts; Arbitration.
                 ------------------------------------ 

                 (i)    In case the Securityholder Agent shall object in
writing to any claim or claims made in any Officer's Certificate as provided
in Section 6.2(g) hereof, the Securityholder Agent and Parent shall attempt in
good faith to agree upon the rights of the respective parties with respect to
each of such claims. If the Securityholder Agent and Parent should so agree, a
memorandum setting forth such agreement shall be prepared and signed by both
parties and shall be furnished to the Escrow Agent. The Escrow Agent shall be
entitled to rely on any such memorandum and distribute shares of Parent Common
Shares from the Escrow Fund in accordance with the terms thereof.

                 (ii)   If no such agreement can be reached after good faith
negotiation, either Parent or the Securityholder Agent may demand arbitration
of the matter unless the amount of the damage or loss is at issue in pending
litigation with a third party, in which event arbitration shall not be
commenced until such amount is ascertained or both parties agree to
arbitration; and in either such event the matter shall be settled by
arbitration conducted by three arbitrators. Parent and the Securityholder
Agent shall each select one arbitrator, and the two arbitrators so selected
shall select a third arbitrator. The arbitrators shall set a limited time
period and establish procedures designed to reduce the cost and time for
discovery while allowing the parties an opportunity, adequate in the sole
judgment of the arbitrators, to discover relevant information from the
opposing parties about the subject matter of the dispute. The arbitrators
shall rule upon motions to compel or limit discovery and shall have the
authority to impose sanctions, including attorneys fees and costs, to the
extent as a court of competent law or equity, should the arbitrators determine
that discovery was sought without substantial justification or that discovery
was refused or objected to without substantial justification. The decision of
a majority of the three arbitrators as to the validity and amount of any claim
in such Officer's Certificate shall be binding and conclusive upon the parties
to this Agreement, and notwithstanding anything in Section 6.2(g) hereof, the
Escrow Agent shall be entitled to act in accordance with such decision and
make or withhold payments out of the Escrow Fund in accordance therewith. Such
decision shall be written and shall be supported by written findings of fact
and conclusions which shall set forth the award, judgment, decree or order
awarded by the arbitrators.

                 (iii)  Judgment upon any award rendered by the arbitrators
may be entered in any court having jurisdiction. Any such arbitration shall be
held within the federal

                                      -20-

 
Northern District of California under the rules then in effect of the American
Arbitration Association. For purposes of this Section 6.2(h), in any
arbitration hereunder in which any claim or the amount thereof stated in the
Officer's Certificate is at issue, Parent shall be deemed to be the prevailing
party in the event that the arbitrators award Parent an amount equal to at
least the sum of one-half (1/2) of the disputed amount plus any amounts not in
dispute; otherwise, the shareholders of the Company as represented by the
Securityholder Agent shall be deemed to be the prevailing party. The non-
prevailing party to an arbitration shall pay its own expenses, the fees of
each arbitrator, the administrative costs of the arbitration, and the
expenses, including without limitation, reasonable attorneys' fees and costs,
incurred by the other party to the arbitration.

           (i)   Securityholder Agent of the Shareholders; Power of Attorney.
                 -----------------------------------------------------------

                 (i)   In the event that the Merger is approved, effective
upon such vote, and without further act of any shareholder, Aaron Sasson shall
be appointed as agent and attorney-in-fact (the "Securityholder Agent") for
                                                 --------------------   
each shareholder of the Company, for and on behalf of shareholders of the
Company, to give and receive notices and communications, to authorize delivery
to Parent of Parent Common Shares from the Escrow Fund in satisfaction of
claims by Parent, to object to such deliveries, to agree to, negotiate, enter
into settlements and compromises of, and demand arbitration and comply with
orders of courts and awards of arbitrators with respect to such claims, and to
take all actions necessary or appropriate in the judgment of Securityholder
Agent for the accomplishment of the foregoing. Such agency may be changed by
the shareholders of the Company from time to time upon not less than thirty
(30) days prior written notice to Parent; provided that the Securityholder
Agent may not be removed unless holders of a two-thirds interest of the Escrow
Fund agree to such removal and to the identity of the substituted agent. Any
vacancy in the position of Securityholder Agent may be filled by approval of
the holders of a majority in interest of the Escrow Fund. No bond shall be
required of the Securityholder Agent, and the Securityholder Agent shall not
receive compensation for his or her services. Notices or communications to or
from the Securityholder Agent shall constitute notice to or from each of the
shareholders of the Company.

                 (ii)  The Securityholder Agent shall not be liable for any
act done or omitted hereunder as Securityholder Agent while acting in a manner
he believes in good faith to be in the best interests of the corporation. The
shareholders of the Company on whose behalf the Escrow Amount was contributed
to the Escrow Fund shall severally indemnify the Securityholder Agent and hold
the Securityholder Agent harmless against any loss, liability or expense
incurred without gross negligence or bad faith on the part of the
Securityholder Agent and arising out of or in connection with the acceptance
or administration of the Securityholder Agent's duties hereunder, including
the reasonable fees and expenses of any legal counsel retained by the
Securityholder Agent.

           (j)   Actions of the Securityholder Agent.  A decision, act, 
                 -----------------------------------  
consent or instruction of the Securityholder Agent shall constitute a decision
of all the shareholders for whom a portion of the Escrow Amount otherwise
issuable to them are deposited in the Escrow Fund and shall be final, binding
and conclusive upon each of such shareholders, and the Escrow

                                      -21-

 
Agent and Parent may rely upon any such decision, act, consent or instruction
of the Securityholder Agent as being the decision, act, consent or instruction
of each every such shareholder of the Company. The Escrow Agent and Parent are
hereby relieved from any liability to any person for any acts done by them in
accordance with such decision, act, consent or instruction of the
Securityholder Agent.

           (k)   Third-Party Claims.  In the event Parent becomes aware of a 
                 ------------------
third-party claim which Parent believes may result in a demand against the
Escrow Fund, Parent shall promptly notify the Securityholder Agent of such
claim in accordance with Section 6.2(g), and the Securityholder Agent, as
representative for the shareholders of the Company, shall be entitled, at
their expense, to participate in any defense of such claim. Parent shall have
the right in its sole discretion to settle any such claim; provided, however,
that except with the consent of the Securityholder Agent, no settlement of any
such claim with third-party claimants shall permit any claim against the
Escrow Fund. In the event that the Securityholder Agent has consented to any
such settlement and acknowledged that the claim is a valid claim against the
Escrow Fund, the Securityholder Agent shall be deemed to have agreed to the
claim by Parent against the Escrow Fund in an amount equal to such settlement.
In the event, the claimed amount is less than the then available escrow, the
Securityholder Agent, as representative for the shareholders of the Company,
at his election, can control the litigation; provided, however, if such claim
                                             --------  ------- 
relates to the business operations of the Company then Parent shall control
the litigation of such claim.

           (l)   Escrow Agent's Duties.
                 --------------------- 

                 (i)    The Escrow Agent shall be obligated only for the
performance of such duties as are specifically set forth herein, and as set
forth in any additional written escrow instructions which the Escrow Agent may
receive after the date of this Agreement which are signed by an officer of
Parent and the Securityholder Agent, and may rely and shall be protected in
relying or refraining from acting on any instrument reasonably believed to be
genuine and to have been signed or presented by the proper party or parties.
The Escrow Agent shall not be liable for any act done or omitted hereunder as
Escrow Agent while acting in good faith and in the exercise of reasonable
judgment, and any act done or omitted pursuant to the advice of counsel shall
be conclusive evidence of such good faith.

                 (ii)   The Escrow Agent is hereby expressly authorized to
disregard any and all warnings given by any of the parties hereto or by any
other person, excepting only orders or process of courts of law, and is hereby
expressly authorized to comply with and obey orders, judgments or decrees of
any court. In case the Escrow Agent obeys or complies with any such order,
judgment or decree of any court, the Escrow Agent shall not be liable to any
of the parties hereto or to any other person by reason of such compliance,
notwithstanding any such order, judgment or decree being subsequently
reversed, modified, annulled, set aside, vacated or found to have been entered
without jurisdiction.

                                      -22-

 
                 (iii)  The Escrow Agent shall not be liable in any respect on
account of the identity, authority or rights of the parties executing or
delivering or purporting to execute or deliver this Agreement or any documents
or papers deposited or called for hereunder.

                 (iv)   The Escrow Agent shall not be liable for the
expiration of any rights under any statute of limitations with respect to this
Agreement or any documents deposited with the Escrow Agent.

                 (v)    In performing any duties under the Agreement, the
Escrow Agent shall not be liable to any party for damages, losses, or
expenses, except for gross negligence or willful misconduct on the part of the
Escrow Agent. The Escrow Agent shall not incur any such liability for (A) any
act or failure to act made or omitted in good faith, or (B) any action taken
or omitted in reliance upon any instrument, including any written statement of
affidavit provided for in this Agreement that the Escrow Agent shall in good
faith believe to be genuine, nor will the Escrow Agent be liable or
responsible for forgeries, fraud, impersonations, or determining the scope of
any representative authority. In addition, the Escrow Agent may consult with
the legal counsel in connection with Escrow Agent's duties under this
Agreement and shall be fully protected in any act taken, suffered, or
permitted by him/her in good faith in accordance with the advice of counsel.
The Escrow Agent is not responsible for determining and verifying the
authority of any person acting or purporting to act on behalf of any party to
this Agreement.

                 (vi)   If any controversy arises between the parties to this
Agreement, or with any other party, concerning the subject matter of this
Agreement, its terms or conditions, the Escrow Agent will not be required to
determine the controversy or to take any action regarding it. The Escrow Agent
may hold all documents and shares of Parent Common Shares and may wait for
settlement of any such controversy by final appropriate legal proceedings or
other means as, in the Escrow Agent's discretion, the Escrow Agent may be
required, despite what may be set forth elsewhere in this Agreement. In such
event, the Escrow Agent will not be liable for damage.

                 Furthermore, the Escrow Agent may at its option, file an
action of interpleader requiring the parties to answer and litigate any claims
and rights among themselves. The Escrow Agent is authorized to deposit with
the clerk of the court all documents and shares of Parent Common Shares held
in escrow, except all cost, expenses, charges and reasonable attorney fees
incurred by the Escrow Agent due to the interpleader action and which the
parties jointly and severally agree to pay. Upon initiating such action, the
Escrow Agent shall be fully released and discharged of and from all
obligations and liability imposed by the terms of this Agreement.

                 (vii)  The parties and their respective successors and
assigns agree jointly and severally to indemnify and hold the Escrow Agent
harmless against any and all losses, claims, damages, liabilities, and
expenses, including reasonable costs of investigation, counsel fees, and
disbursements that may be imposed on the Escrow Agent or incurred by the
Escrow Agent in connection with the performance of the Escrow Agent's duties
under this

                                      -23-

 
Agreement, including but not limited to any litigation arising from this
Agreement or involving its subject matter.

                 (viii) The Escrow Agent may resign at any time upon giving at
least thirty (30) days' written notice to the parties; provided, however, that
no such resignation shall become effective until the appointment of a
successor escrow agent which shall be accomplished as follows: the parties
shall use their best efforts to mutually agree on a successor escrow agent
within thirty (30) days after receiving such notice. If the parties fail to
agree upon a successor escrow agent within such time, the Escrow Agent shall
have the right to appoint a successor escrow agent authorized to do business
in the State of California. The successor escrow agent shall execute and
deliver an instrument accepting such appointment and it shall, without further
acts, be vested with all the estates, properties, rights, powers, and duties
of the predecessor escrow agent as if originally named as escrow agent. The
Escrow Agent shall be discharged from any further duties and liability under
this Agreement.

           (m)   Fees.  All fees of the Escrow Agent for performance of its 
                 ---- 
duties hereunder shall be paid by Parent. It is understood that the fees and
usual charges agreed upon for services of the Escrow Agent shall be considered
compensation for ordinary services as contemplated by this Agreement. In the
event that the conditions of this Agreement are not promptly fulfilled, or if
the Escrow Agent renders any service not provided for in this Agreement, or if
the parties request a substantial modification of its terms, or if any
controversy arises, or if the Escrow Agent is made a party to, or intervenes
in, any litigation pertaining to this escrow or its subject matter, the Escrow
Agent shall be reasonably compensated by Parent for such extraordinary
services and reimbursed for all costs, attorney's fees, and expenses
occasioned by such default, delay, controversy or litigation.

           and approximately $20,000 payable to US counsel. The Company has
           incurred (and will continue to incur) additional legal fees in

                            SHAREHOLDER AGREEMENT

     THIS AGREEMENT is made and entered into as of December 23, 1998, between
Genesys Telecommunications Laboratories, Inc, a California corporation
("Parent"), and the undersigned Shareholders (each, a "Shareholder" and
  ------                                               -----------     
collectively, the "Shareholders") of Plato Software Corporation, a Delaware
                   ------------                                            
corporation (the "Company").  All capitalized terms used and not otherwise
                  -------                                                 
defined herein shall have the meanings given them in the Agreement and Plan of
Reorganization dated December 9, 1998 entered into by and among Parent, the
Company and the Merger Sub referred to therein (the "Merger Agreement").  Each
                                                     ----------------         
Shareholder of the Company is entering into this Agreement.

                                   RECITALS:

     Pursuant to the Merger Agreement, Parent will acquire from the Shareholders
all of the issued and outstanding Company Common Stock and assume all
outstanding Company Options in exchange for an aggregate of 250,000 shares of
Parent Common Shares.  The Parent Common Shares to be so issued in respect of
shares of Company Common Stock ("Parent Shares") have not been registered under
                                 -------------                                 
the Securities Act of 1933, as amended (the "Securities Act"), in reliance upon
                                             --------------                    
the exemptions from registration provided by Rule 506 and/or Section 4(2) of the
Securities Act, and accordingly such shares constitute "restricted securities"
within the meaning of Rule 144(a)(3) under the Securities Act.

     In consideration of the premises and the mutual representations, warranties
and covenants herein contained, the parties hereto have agreed and do hereby
agree as follows:

     1.    Restricted Shares; Legend.
           ------------------------- 

           1.1   Parent Common Stock Restrictions.  No Shareholder will make 
                 --------------------------------  
any sale, transfer or other disposition of the Parent Shares, unless (i) there
is in effect a registration statement under the Securities Act covering the
proposed transfer; (ii) such proposed transfer is within the limitations of
and in compliance with the terms and provisions of Rule 144 under the
Securities Act; or (iii) Parent receives an unqualified written opinion of
legal counsel addressed to Parent and in form and substance reasonably
satisfactory to Parent's counsel, to the effect that the proposed transfer of
Parent Shares may be effected without registration under the Securities Act.

           1.2   Each certificate for Parent Shares shall be stamped or
otherwise imprinted with a legend stating in substance:

           "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
           REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH
           SHARES MAY NOT BE

 
           SOLD, OFFERED FOR SALE, TRANSFERRED, ASSIGNED, OR OTHERWISE
           DISPOSED OF, DIRECTLY OR INDIRECTLY, EXCEPT (I) PURSUANT TO AN
           EFFECTIVE REGISTRATION STATEMENT RELATED THERETO, (II) IN
           COMPLIANCE WITH RULE 144 OR (III) PURSUANT TO AN OPINION OF COUNSEL
           ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED
           UNDER THE U.S. SECURITIES ACT OF 1933."

           1.3   In connection with the limitations on disposition with
respect to the Parent Shares contained in this Agreement, Parent will issue
stop transfer instructions to its transfer agent with respect to such shares.

           1.4   Each Shareholder understands that Parent is under no
obligation to register the sale, transfer or other disposition of the Parent
Shares, except as specifically provided in this Agreement.

           1.5   In connection with any sales by a Shareholder of Parent
Shares in compliance with the limitations on disposition set forth in this
Agreement, Parent agrees to notify its transfer agent that the legend set
forth in Section 1.2 may be removed from such Parent Shares being sold by the
Shareholder at the time of such sales.

     2.    Shareholder's Representations.  Each Shareholder severally
           -----------------------------     
represents, warrants and covenants to Parent with respect to such Shareholder
that:

           2.1   The Shareholder understands that the Parent Shares to be
issued under the Merger Agreement have not been registered under the
Securities Act on the basis that the sale and issuance of securities
thereunder is exempt from such registration pursuant to the provisions of Rule
506 and/or Section 4(2) under the Securities Act, and that Parent's reliance
on such exemptions is based on Shareholder's representations set forth herein.

           2.2   The Parent Shares to be acquired by the Shareholder will be
acquired for investment for the Shareholder's own account, not as a nominee or
agent, and not with a view to the resale or distribution of any part thereof,
and that the Shareholder has no present intention of selling, granting any
participation in, or otherwise distributing the same. By executing this
Agreement, the Shareholder further represents that the Shareholder does not
have any contract, undertaking, agreement or arrangement with any person to
sell, transfer or grant participation to such person or to any third person,
with respect to any of the Parent Shares to be issued under the Merger
Agreement.

           2.3   The Shareholder understands that the Parent Shares are
"restricted securities" within the meaning of Rule 144(a)(3) and that such
shares may not be sold, transferred or otherwise disposed of without
registration under the Securities Act or an exemption therefrom, and that in
the absence of an effective registration statement covering such shares or an
available exemption from registration under the Securities Act, such shares
must be held indefinitely.


                                      -2-

 
           2.4   The Shareholder acknowledges that he is aware of Rule 144
under the Securities Act, which permits limited public resales of "restricted
securities" subject to the satisfaction of certain conditions. The Shareholder
understands that under Rule 144, except as otherwise provided by section (k)
of that Rule, the conditions include, among other things: the availability of
certain current public information about the issuer, the resale occurring not
less than one year after the party has purchased and paid for the securities
to be sold and limitations on the amount of securities to be sold and the
manner of sale. The Shareholder acknowledges that in the event all of the
requirements of Rule 144 are not met, registration under the Securities Act,
or an exemption from registration will be required for any disposition of the
Parent Shares. The Shareholder understands that although Rule 144 is not
exclusive, the Commission has expressed its opinion that persons proposing to
sell restricted securities received other than in a registered offering or
pursuant to Rule 144 will have a substantial burden of proof in establishing
that an exemption from registration is available for such offers or sales and
that such persons and the brokers who participate in the transactions do so at
their own risk.

           2.5   The Shareholder has consulted his own legal and tax advisors
regarding the consequences of the transaction contemplated by the Merger
Agreement and acknowledges that he is not relying upon, nor has he received,
any legal or tax advice from Parent or its legal counsel or accountants.

           2.6   The Shareholder is aware of Parent's business and financial
condition and has sufficient information about Parent to reach an informed and
knowledgeable decision to acquire the Parent Shares in the transaction
contemplated by the Merger Agreement. Shareholder acknowledges he has
previously received copies of Parent's Annual Report on Form 10-K for the
fiscal year ended June 30, 1997, and its Quarterly Report on Form 10-Q for the
three month period ending September 30, 1998, and that he has had the
opportunity to receive additional information concerning Parent. The
Shareholder further represents that he has had an opportunity to ask questions
and receive answers from Parent regarding the business and financial condition
of Parent.

           2.7   The Shareholder agrees to complete and execute the
Questionnaire attached hereto as Exhibit A as promptly as possible after
                                 ---------          
receipt from Parent of the draft of the Form S-3 registration statement
contemplated to be filed as set forth in Section 4 of this Agreement, and in
any case, prior to Parent's filing of such Form S-3.

     3.    Transfers of Parent Shares.  With respect to any disposition or 
           --------------------------   
attempted disposition of any Parent Shares, each Shareholder will comply with
the following procedure:

           3.1   With respect to any sale of Parent Shares made pursuant to
Rule 144, the Shareholder will provide Parent with copies of appropriate
documentation evidencing compliance with Rule 144.

           3.2   With respect to a proposed disposition of Parent Shares not
registered under the Securities Act and other than pursuant to Rule 144, the
Shareholder will give prior written notice to Parent describing the manner and
circumstances of the proposed disposition in sufficient detail to enable
Parent to evaluate whether the proposed disposition of such shares


                                      -3-

 
satisfies the requirements of the Securities Act and this Agreement. Upon
receipt of such written notice, Parent shall promptly notify the Shareholder
either (i) that the Parent Shares may be disposed of in the manner and under
the circumstances described, or (ii) that on the basis of the information
provided the Parent Shares may not be disposed of prior to the receipt by
Parent of an opinion of counsel reasonably satisfactory to Parent and its
counsel to the effect that the proposed disposition of Parent Shares may be
effected without registration under the Securities Act.

           3.3   With respect to a disposition of Parent Shares registered
under the Securities Act, each Shareholder will dispose of such Common Shares
as provided in the Form S-3 registration statement.

     4.    Registration Rights.

to Section 4.6 below, on or before April 30, 1998, Parent will file a

completed; provided, however, that, each Shareholder agrees, by acquisition of
           --------  -------  ----  
the Parent Shares, that:

                 (a)   Upon receipt of any notice from Parent of (i) the 
happening of any event which makes any statements made in the registration
statement or related prospectus filed pursuant to this Section 4, or any
documents incorporated or deemed to be incorporated therein by reference,
untrue in any material respect or which requires the making of any changes in
such registration statement or prospectus so that, in the case of such
registration statement it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and that in the case
of the prospectus, it will not contain any untrue statement of a material fact
or omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading or (ii) that, in the judgment of Parent's Board of Directors, it is
advisable to suspend use of the prospectus for a discrete period of time due
to pending corporate developments, public filings with the Commission or that
there exists material nonpublic information about Parent that the Board of
Directors, acting in good faith, determines not to disclose in a registration
statement, then Shareholder will forthwith discontinue, for a period not to
exceed forty-five (45) days (and not to exceed ninety (90) days in the
aggregate), disposition of such Parent Shares covered by such registration
statement or prospectus until it is advised in writing by Parent that use of
the applicable prospectus may be resumed, and has received copies of any
additional or supplemental filings that are incorporated or deemed to be
incorporated by reference in such prospectus. Parent shall use its reasonable
efforts to insure that the use of the prospectus may be resumed as soon as
practicable.

                 (b)   The Shareholder shall provide all such information and
materials to Parent and take all such action as may be required in order to
permit Parent to comply with all applicable requirements of the Commission and
to obtain any desired acceleration of the effective date of such registration
statement. Such provision of information and materials is a condition
precedent to the obligations of Parent pursuant to this Agreement. The
offerings made pursuant to such registration shall not be underwritten.

                 (c)   The Shareholder shall abide by Parent's internal insider

     5.    Obligations of Parent.
           --------------------- 

           5.1   Subject to the limitations of Sections 2, 3 and 4 above,
Parent shall (i) prepare and file with the Commission the Form S-3
registration statement in accordance with Section 4.2 hereof with respect to
the shares of Registrable Securities; (ii) prepare and file with the
Commission such amendments and supplements to such registration statement and
the prospectus used in connection therewith as may be necessary, and to comply
with the provisions of the Securities Act with respect to the sale or other
disposition of all securities proposed to be registered in each such
registration statement as promptly as practicable following the Closing Date
until the second anniversary of the Closing Date; (iii) furnish to each
Shareholder such number of copies of any prospectus (including any preliminary
prospectus and any amended or supplemented prospectus) in conformity with the
requirements of the Securities Act, and such other documents as the
Shareholder may reasonably request in order to effect the offering and sale of
the Registrable Securities to be offered and sold, but only while Parent shall
be required under the provisions hereof to cause the registration statement to
remain current; and (iv) use its


                                      -6-

 
commercially reasonable efforts to register or qualify the shares of the
Registrable Securities covered by such registration statement under the
securities or blue sky laws of such jurisdictions as a Shareholder shall
reasonably request (provided that Parent shall not be required in connection
therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such jurisdiction where it has
not been qualified).

     5.2   Parent shall notify each Shareholder, (A) when a prospectus or any
prospectus supplement or post-effective amendment has been filed, and, with
respect to the registration statement or any post-effective amendment, when
the same has become effective; (B) of any request by the Commission or any
other federal or state governmental authority during the period of
effectiveness of the registration statement for amendments or supplements to
the registration statement or related prospectus or for additional information
relating to the registration statement, (C) of the issuance by the Commission
or any other federal or state governmental authority of any stop order
suspending the effectiveness of the registration statement or the initiation
of any proceedings for that purpose, (D) of the receipt by Parent of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose; or (E) of the happening of any event which makes any statement made
in the registration statement or related prospectus or any document
incorporated or deemed to be incorporated therein by reference untrue in any
material respect or which requires the making of any changes in the
registration statement or prospectus so that, in the case of the registration
statement, it will not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading, and that in the case of the prospectus,
it will not contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. Parent may, upon the happening of any event (i) of the
kind described in clauses B, C, D, or E hereof, or (ii) that, in the good
faith judgment of Parent's Board of Directors, renders it advisable to suspend
use of the prospectus for no more than forty-five (45) days due to pending
corporate developments, public filings with the Commission or similar events,
suspend use of the prospectus on written notice to each Shareholder, in which
case each Shareholder shall discontinue disposition of Registrable Securities
covered by the registration statement or prospectus until copies of a
supplemented or amended prospectus are distributed to Shareholder or until the
Shareholder is advised in writing by Parent that the use of the applicable
prospectus may be resumed. Parent shall use its reasonable efforts to ensure
that the use of the prospectus may be resumed as soon as practicable. Parent
shall use every reasonable effort to obtain the withdrawal of any order
suspending the effectiveness of the registration statement, or the lifting of
any suspension of the qualification (or exemption from qualification) of any
of the securities for sale in any jurisdiction, at the earliest practicable
time. Parent shall, upon the occurrence of any event contemplated by clause E
above, prepare a supplement or post-effective amendment to the registration
statement or a supplement to the related prospectus or any document
incorporated therein by reference or file any other required document so that,
as thereafter delivered to the purchasers of the Registrable Securities being
sold thereunder, such prospectus will not contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein


                                      -7-

 
or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

           5.3   In connection with any offering of shares of Registrable
Securities registered on Form S-3 pursuant to this Agreement, Parent shall
instruct the transfer agent and registrar of the Parent Shares to remove the
restrictive legend and release any stop transfer orders with respect to the
shares of Registrable Securities being sold.

           5.4   Parent shall apply for listing on the Nasdaq National Market
(or on such market as Parent Shares are currently trading) the shares of
Registrable Securities registered on Form S-3 pursuant to this Agreement.

           5.5   Rule 144 Reporting.  With a view to making available the 
                 ------------------ 
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the Restricted Securities to the public without

                 (a)   Make and keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act;

Securities, to furnish to the Shareholders upon request a written statement by
Parent as to its compliance with the reporting requirements of said Rule 144.

     6.    Availability of Form S-3.  Parent represents that it is currently 
           ------------------------     
eligible to utilize Form S-3 for registration of the Parent Shares.

     7.    Notices.  All notices and other communications hereunder shall be in

number of copies of the Prospectus as such broker or dealer may reasonably
require.

conditions set forth herein and will notify Parent upon the completion of any
and all sales of its securities covered by the Registration Statement.

     (4)   The Shareholder has received a copy of the Registration Statement and
has reviewed the Registration Statement and will review any amendments thereto
promptly after receipt thereof and agrees to inform Parent of any material
facts, trends, or pending or existing conditions known to the Shareholder that
relate to the Shareholder and his distribution of Parent Common Shares and not

     WHEREAS, it is intended that the Merger will constitute a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986 as

                                                                      ---------
Regulations") of the Securities and Exchange Commission (the "Commission").
- -----------                                                   ----------   

        NOW, THEREFORE, intending to be legally bound, the parties hereby agree
as follows:

        1.  Acknowledgments by Affiliate.  Affiliate acknowledges and 
            ----------------------------                             
understands that the representations, warranties and covenants by Affiliate set
forth herein will be relied upon by Parent, the Company, and their respective
"affiliates", counsel and accountants, and that substantial losses and damages
may be incurred by these persons if Affiliate's representations, warranties or
covenants are not true when given or are breached by Affiliate. Affiliate has
carefully read this Agreement and the Merger Agreement and has had the
opportunity to discuss the requirements of this Agreement with his professional
advisors who are qualified to advise him with regard to such matters.

        2.  Compliance with the Securities Act.
            ---------------------------------- 

            (a)  Affiliate has been advised that (i) the issuance of shares of
Parent Common Stock ("Parent Common Shares") in connection with the Merger
                      --------------------      
will be effected pursuant to a private placement exemption from the
registration requirements of the Securities Act of 1933 as amended (the
"Securities Act") and as such will be deemed "restricted securities" within
 --------------
 the meaning of Rule 144 promulgated thereunder and resale of such shares will
 be subject to certain restrictions as set forth in Rule 144 and 145 of the
 Securities Act unless otherwise transferred pursuant to an effective
 registration statement under the Securities Act or an appropriate exemption
 from registration, (ii) Affiliate may be

 
deemed to be an affiliate of Company, (iii) no sale, transfer or other
disposition by Affiliate of any Parent Common Shares received by Affiliate will
be registered under the Securities Act, except as provided in that certain
Shareholder Agreement entered into by and among Parent, Affiliate and certain
other shareholders of the Company. Affiliate accordingly agrees not to sell,
transfer or otherwise dispose of any Parent Common Shares issued to Affiliate in
the Merger unless (i) such sale, transfer or other disposition is made in
conformity with the requirements of Rule 144 and Rule 145(d) promulgated under
the Securities Act, (ii) Affiliate delivers to Parent a written opinion of
counsel, reasonably acceptable to Parent in form and substance, that such sale,
transfer or other disposition is otherwise exempt from registration under the
Securities Act, or (iii) such shares are registered under the Securities Act.

            (b)  Parent will give stop transfer instructions to its transfer
agent with respect to any Parent Common Shares received by Affiliate pursuant to
the Merger and there will be placed on the certificates representing such Parent
Common Shares, or any substitutions therefor, a legend stating in substance:

          "The shares represented by this certificate have not been registered
          under the Securities Act of 1933, as amended (the "Securities Act")
          and may not be offered, sold or pledged, transferred or otherwise
          disposed of except (1) pursuant to an effective registration statement
          under the Securities Act, (2) pursuant to Rule 144, or (3) pursuant to
          a written opinion of counsel, reasonably acceptable to this
          corporation in form and substance, that such transfer is exempt from
          registration under the Securities Act."

The legend set forth above shall be removed (by delivery of a substitute
certificate without such legend) and Parent shall so instruct its transfer
agent, if Affiliate delivers to Parent satisfactory written evidence that (i)
the shares have been sold in compliance with Rule 144 (in which case, the
substitute certificate will be issued in the name of the transferee), or (ii)
any of the other conditions specified in Section 2(a) hereof have been
satisfied.
