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

9.3.1.  Prior to January 1, 2001 (the "Outside Date"), at any meeting of
shareholders of Level 8, each WCAS Party shall grant a proxy to one or more
individuals named by Level 8 from time to time to vote all that WCAS Party's
Level 8 Shares as Level 8 may from time to time request by notice given to that
WCAS Party not fewer than three business days  before a particular meeting.

9.3.2.  Prior to the Outside Date, no WCAS Party may sell, exchange or otherwise
assign or transfer any Level 8 Shares without the prior written consent of Level
8.  Nothing in the preceding sentence, however, shall be deemed to prohibit any
transfer of any Level 8 Shares to a partner or affiliate of a WCAS Party, as
long as that partner or affiliate agrees to be bound by the provisions of this
section 9.3.

9.3.3.  All certificates evidencing Level 8 Shares issued under this agreement
or upon exercise of the Level 8 Warrants shall bear the following legends:

          "The shares evidenced by this certificate were issued in a transaction
          exempt from the registration requirements of the Securities Act of
          1933, and such shares may not be transferred in the absence of an
          opinion of counsel satisfactory to the Company that such transfer may
          be effected without registration under the Securities Act of 1933."

          "The voting and transfer of the shares evidenced by this certificate
          are subject to the provisions of an agreement dated November 23,
          1998, a copy of which is on file at the office of the Company."

9.3.4.  If, at any time before the Outside Date, Level 8 determines to file a
registration statement under the Securities Act of 1933 for an underwritten sale
to the public of shares of its common stock in whole or in part by any of Level
8's shareholders, Level 8 shall, each such time, promptly give each WCAS Party
written notice of its intent to file a registration statement and shall include
all shares held by any WCAS Party with respect to which Level 8 has received a
written request within 15 days after Level 8 has given notice to the WCAS Party
as set forth above specifying the number of shares to be included.
Notwithstanding the foregoing, however, in connection with any such offering,
Level 8 shall not be required to include a WCAS Party's shares in the offering,
unless the WCAS Party shall have accepted the terms of the underwriting and then
only in such quantity as will not, in the written opinion of the underwriter,
exceed the maximum number of shares that can be marketed without materially and
adversely affecting the offering.  If, as a consequence of the provisions of the
preceding sentence, the number of a WCAS Party's shares included in the offering
is reduced, such reduction shall be made pro rata among the shareholders to be
included in the offering on the basis of the percentage of shares of the
shareholders to be included, and the percentage of the reduction shall not be
more than the percentage of reduction applicable to any other selling
shareholder in the offering.  The rights with respect to such offering by any
WCAS Party whose shares are included shall not be less, and the obligations with
respect to such offering by any such WCAS Party shall not be greater, than those
of any other shareholder whose shares are included in such offering.

9.4.  Related Party Transactions.  Until the earlier of the Outside Date or the
      --------------------------                                               
first date on which the WCAS Parties no longer beneficially own (as defined in
the rules under the Exchange Act) at least 50% of the shares of common stock of
Level 8 represented by the Level 8 Shares and the Level 8 Shares issuable upon
exercise of the Level 8 Warrants issued pursuant to section 1, Level 8 shall
not, and shall not permit any of its subsidiaries to, engage in any transaction
with Liraz or any affiliate of Liraz on 

                                       E-11
<PAGE>
 
terms less favorable to Level 8 or any such subsidiary than the terms on which
an unaffiliated third party would engage in such transaction.

9.5.  Further Assurances.  From time to time after the Closing, each party shall
      ------------------                                                        
take such action and execute and deliver such documents as the others may
reasonably request to carry out the transactions contemplated by this agreement.

9.6.  D&O Matters.
      ----------- 

9.6.1. Level 8 agrees that, for a period of six years after the Closing and
except to the extent otherwise required by law, it shall cause the certificate
of incorporation and by-laws of the Company to contain provisions with respect
to indemnification and exculpation from liability no less favorable to the
individuals who, on or prior to the Closing, were directors, officers, employees
or agents of the Company (collectively, the "Indemnified Parties") than those
set forth in the Company's certificate of incorporation and by-laws in effect
immediately before the Closing.

9.6.2. For a period of six years after the Closing, Level 8 shall use all
reasonable efforts to cause the Company to maintain directors' and officers'
liability insurance covering those Indemnified Parties who are currently covered
by the Company's directors' and officers' liability insurance policy on terms no
less favorable to those Indemnified Parties than the terms of the insurance
coverage in effect on the date of the Closing for Level 8's own directors and
officers.

9.6.3. The Indemnified Parties and the Company are intended beneficiaries of
this section 9.6.

10.   Indemnification.
      --------------- 

10.1. General.
      ------- 

10.1.1. Subject to the provisions of this section 10, each WCAS Party shall
indemnify and hold Level 8 harmless from and against all losses, liabilities,
damages and expenses (including reasonable attorneys' fees) resulting from any
breach of warranty or agreement, or any misrepresentation, by it under this
agreement.

10.1.2. Subject to the provisions of this section 10, Level 8 shall indemnify
and hold each WCAS Party harmless from and against all losses, liabilities,
damages and expenses (including reasonable attorneys' fees) resulting from any
breach of warranty or agreement, or any misrepresentation, by it under this
agreement.

10.2. Exclusivity.  Except as specifically set forth in this agreement, no
      -----------                                                         
party to this agreement has made, or shall have liability for, any
representation, warranty or agreement, express or implied, in connection with
the transactions contemplated by this agreement, including any representation or
warranty, express or implied, as to the accuracy or completeness of any
information regarding the Company or Level 8.

10.3. Survival; Manner of Claims.  The representations and warranties in this
      --------------------------                                             
agreement shall survive the Closing.  However, a party shall have no liability
under this agreement for breach of warranty or misrepresentation, unless a claim
therefor is asserted by another party in a written notice setting forth the
representations and warranties with respect to which the claim is made, the
facts giving rise to and the alleged basis for the claim and the amount of
liability asserted by reason of the claim.

10.4. Defense of Claims by Third Parties.  If any claim is made against a party
      ----------------------------------                                       
that, if sustained, would give rise to a liability of another party under this
agreement, the party against whom the claim is made shall promptly cause notice
of the claim to be delivered to the other party or parties and shall afford the
other party or parties and its or their counsel, at its or their  sole expense,
the opportunity to defend or settle the claim.  The failure to provide the
notice referred to above shall  not relieve the indemnifying party of liability
under this agreement, except to the extent the indemnifying party has actually
been prejudiced by such failure.  If any claim is compromised or settled without
the consent of the indemnifying party, no liability shall be imposed upon the
indemnifying party by reason of the claim.

11.  Miscellaneous.
     ------------- 

11.1. Finders.  Each party represents and warrants to the others that it has
      -------

this agreement or the transactions contemplated by this agreement.

      -------------                                                       
accordance with the law of the state of New York, without giving effect to its
conflicts of law principles.

11.3. Headings.  The section headings of this agreement are for reference
      --------

                     -------                                                    
    shall not, and shall not permit any of its subsidiaries to, engage in any
    transactions with Level 8 or Level 8's other affiliates on terms less
    favorable to Borrower or such subsidiaries than the terms on which an
    unaffiliated third party would engage in such transaction; and (b) Borrower
    shall not make any transfer of funds or other property to Level 8 or Level
    8's other affiliates (other than Borrower's subsidiaries), other than
    payments not in contravention of clause (a) above; and (c) Borrower shall
    not pay or declare any distributions or dividends, or redeem or repurchase
    any of its stock or other securities from Level 8 or any of Level 8's other
    affiliates.

               "(3)  Streamlined Provisions.  At such time as the total unpaid
                     -----------------------                                  
    principal balance of all outstanding Loans is $13,000,000 or less, the
    following provisions (the `Streamlined Provisions') shall apply:

               "(a) Daily reporting of transactions and daily schedules and
    assignments of Receivables and schedules of collections, called for by
    Section 4.3 of this Loan Agreement, will not be required.  Instead, the
    Borrower shall provide GBC with a monthly Borrowing Base Certificate, in
    such form as GBC shall from time to time specify, within 10 days after the
    end of each month.  In the event, as of the end of any month, the total of
    all Loans and all other Obligations exceeds the Credit Limit, Borrower
    shall immediately pay the 

                                       E-21
<PAGE>
 
    amount of the excess to GBC.

               "(b)  Delivery of the proceeds of Receivables and other
    Collateral within one business day after receipt, as called for by Sections
    4.4 and 5.4 of this Loan Agreement will not be required.

               "(c) The Streamlined Provisions shall immediately terminate if
    any Event of Default or any event which, with notice or passage of time or
    both, would constitute an Event of Default, occurs and is continuing.

               "(d)  While the Streamlined Provisions are in effect, the total
    principal balance of the Loans may not, thereafter, exceed $13,000,000,
    unless Borrower elects, by at least three Business Days' prior written
    notice to GBC, to terminate the Streamlined Provisions.  In the event
    Borrower wishes to terminate the Streamlined Provisions, Borrower shall
    provide GBC with such information relating to the Receivables and other
    Collateral as GBC shall specify in order to enable GBC to complete its
    normal Receivables and Collateral review, at least three Business Days
    prior to the date the Streamlined Provisions are to terminate.

               "(e)  Upon termination of the Streamlined Provisions under clause
    (c) or (d) above, the Borrower shall, then and thereafter, provide GBC with
    the daily reporting of transactions and daily schedules and assignments of
    Receivables and schedules of collections, as called for by Section 4.3 of
    the Loan Agreement, and the Borrower shall deliver all proceeds of
    Receivables and other Collateral to GBC, within one business day after
    receipt, as called for by Sections 4.4 and 5.4 of the Loan Agreement."

    5.  DELETE TERMINATION FEE. The portion of Section 3 of the Schedule, which
        -----------------------                                                
presently reads as follows:  "Termination Fee:  $20,000 per month for each month
(or portion thereof) from the effective date of termination to the Maturity
Date." is amended to read as follows:

               "Termination Fee:  None."

    6.  WELSH CARSON--CONFORMING CHANGES.
        ---------------------------------

read as follows:

               "Level 8's equity ownership decreases to less than 51%".

NEITHER THIS WARRANT NOR ANY SHARES ACQUIRED UPON EXERCISE OF THIS WARRANT HAVE
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") OR UNDER ANY STATE
SECURITIES LAWS.  NEITHER THIS WARRANT NOR ANY SUCH SHARES MAY BE SOLD, OFFERED

Warrant No. __   For the Purchase of _______ Shares



                             LEVEL 8 SYSTEMS, INC.

                         COMMON STOCK PURCHASE WARRANT



    This certifies that, for value received, ____________ _____________________
or its successors in interest, assigns or transferees (collectively, the
"Warrant Holder") is entitled to subscribe for and purchase from Level 8
Systems, Inc., a New York corporation (the "Company"), ______ shares of the
Company's common stock (the "Warrant Shares") for $12.00 a share.  The number of
Warrant Shares and the purchase price for each Warrant Share are subject to
adjustment from time to time as provided in this Warrant (such purchase price,
as so adjusted from time to time, the "Exercise Price").

1.  Exercise.
    -------- 

(a)  This Warrant may be exercised at any time and from time to time, in whole
or in part, on or prior to 5:00 p.m., New York time, on December 31, 2002.

(b)  This Warrant may be exercised by the Warrant Holder, in whole or in part,
by (i) delivering to the Company a duly executed notice of exercise in the
form of annex A and (ii) at the Warrant Holder's option, either (A)
delivering a check payable to (or wire transfer to the account of) the
Company in an amount equal to the product of (1) the Exercise Price and (2)
the number of Warrant Shares as to which this Warrant is being exercised
(such product, the "Total Exercise Price") or (B) delivering to the Company
a letter (the "Cashless Exercise Letter") pursuant to which the Warrant
Holder surrenders a portion of the Warrant having a Deemed Value (as
defined below) equal to the Total Exercise Price.  For these purposes, (i)
the term "Deemed Value" means the product of (A) an amount equal to (1) the
Market Price (as defined below) of a share of the Company's common stock,
reduced by (2) the Exercise Price, and (B) the number of Warrant Shares as
to which the Warrant is then being surrendered pursuant to the Cashless
Exercise Letter, and (ii) the term "Market Price" means the average market
price of the Company's common stock on the 20 trading days preceding the
date of exercise; if the common stock at the time is listed on any national
securities exchange, the Market Price on any day shall be the last sale
price of the common stock on that day; if the common stock is not so listed
but is traded on NASDAQ, 

                                     E-26
<PAGE>
 
the Market Price on any day shall be the last reported sale price on that day,
or, if no sale price shall have been reported, the mean between the bid and
asked prices on that day, all as reported in the Wall Street Journal.

(c)  This Warrant shall be deemed to have been exercised immediately prior to
the close of business on the date of delivery of a duly executed notice of
exercise, together with the amount (in cash or by delivering the Cashless
Exercise Letter) payable or deliverable upon exercise of this Warrant.
Thereafter, the rights of the Warrant Holder, as such, with respect to the
number of Warrant Shares as to which this Warrant is being exercised (and,
if applicable, surrendered as payment pursuant to the Cashless Exercise
Letter) shall cease, and the Warrant Holder shall be deemed to be the
record holder of the shares of common stock issuable upon such exercise.
As soon as practicable after the exercise of this Warrant, the Company
shall issue in the name of and deliver to the Warrant Holder, or as the
Warrant Holder (upon payment by the Warrant Holder of any applicable
transfer taxes) may direct, a certificate or certificates for the number of
fully paid and nonassessable shares of common stock to which the Warrant
Holder shall be entitled upon such exercise.  In the event of partial
exercise of this Warrant and, if applicable, partial surrender of this
Warrant pursuant to the Cashless Exercise Letter, this Warrant shall be
delivered to the Company, and the Company shall issue and deliver to the
Warrant Holder a new Warrant evidencing the rights to purchase the
remaining Warrant Shares, which new Warrant shall in all other respects be
identical to this Warrant.

2.  Certain Adjustments.  This Warrant shall be subject to adjustment as
    -------------------                                                 
follows:

         (a) In case the Company shall (i) pay a stock dividend or make a
     distribution to holders of common stock in shares of its common stock, (ii)
     subdivide its outstanding shares of common stock, (iii) combine its
     outstanding shares of common stock into a smaller number of shares or (iv)
     issue by reclassification of its shares of common stock any shares of
     capital stock of the Company, (v) the Exercise Price shall be increased or
     decreased, as the case may be, to an amount that shall bear the same
     relation to the Exercise Price in effect immediately prior to such action
     as the total number of shares outstanding immediately prior to such action
     shall bear to the total number of shares outstanding immediately after such
     action and (vi) this Warrant automatically shall be adjusted so that it
     shall thereafter evidence the right to purchase the kind and number of
     Warrant Shares or other securities the Warrant Holder would have owned and
     would have been entitled to receive after such action, if this Warrant had
     been exercised immediately prior to such action or any record date with
     respect thereto. An adjustment made pursuant to this subparagraph (a) shall
     become effective retroactively immediately after the record date, in the
     case of a dividend or distribution of common stock, and shall become
     effective immediately after the effective date, in the case of a
     subdivision, combination or reclassification.

         (b) In case the Company shall fix a record date for the making of a
     distribution to all holders of common stock (including any such
     distribution made in connection with a consolidation or merger in which the
     Company is the continuing corporation) of (i) assets (other than cash
     dividends or cash distributions payable out of consolidated net income or
     retained earnings or dividends payable in common stock), (ii) evidences of
     indebtedness or other debt or equity securities of the Company, or of any
     corporation other than the Company (except for the common stock of the
     Company) or (iii) subscription rights, options or warrants to purchase any
     of the foregoing assets or securities, whether or not such rights, options
     or warrants are immediately exercisable (hereinafter collectively called
     "Distributions on Common stock"), the Company shall make provision for the
     Warrant Holder to receive upon exercise of this Warrant, a proportional
     amount (depending upon the extent to which this Warrant is exercised) of
     such 

                                     E-27
<PAGE>
 
     assets, evidences of indebtedness, securities or such other rights, as
     if such Warrant Holder had exercised this Warrant on or before such record
     date.

         (c) In case of any consolidation or merger of the Company with or into
     another corporation or the sale of all or substantially all the assets of
     the Company to another corporation, this Warrant thereafter shall be
     exercisable for the kind and amount of shares of stock or other securities
     or property to which a holder of the number of shares of common stock of
     the Company deliverable upon exercise of this Warrant would have been
     entitled upon such consolidation, merger or sale; and, in such case,
     appropriate adjustment shall be made in the application of the provisions
     in this paragraph 2, to the end that the provisions set forth in this
     paragraph 2 (including provisions with respect to changes in and
     adjustments of the Exercise Price) shall thereafter be applicable, as
     nearly as reasonably may be, in relation to any shares of stock or other
     securities or property thereafter deliverable upon the exercise of this
     Warrant.

         (d) Upon the occurrence of each adjustment or readjustment of the
     Exercise Price or any change in the number of Warrant Shares or in the
     shares of stock or other securities or property deliverable upon exercise
     of this Warrant pursuant to this paragraph 2, the Company at its expense
     shall promptly compute such adjustment or readjustment and change in
     accordance with the terms hereof and furnish to each Warrant Holder a
     certificate signed by the chief financial officer of the Company, setting
     forth such adjustment or readjustment and change and showing in detail the
     facts upon which such adjustment or readjustment and change is based.

         (e) The Company shall not be required upon the exercise of this Warrant
     to issue any fraction of shares, but shall make any adjustment therefor by
     rounding the number of shares obtainable upon exercise to the next higher
     whole number of shares.


3.  Notice to Warrant Holder.  If at any time,
    ------------------------                  

         (a) the Company shall take any action which would require an adjustment
     in the Exercise Price or in the number of Warrant Shares pursuant to
     paragraph 2; or

         (b) the Company shall authorize the granting to the holders of its
     common stock of any Distributions on Common Stock as set forth in paragraph
     2(b), and notice thereof shall be given to holders of common stock; or

         (c) the Company shall issue any additional shares of common stock or
     declare any dividend (or any other distribution) on its common stock (other
     than its regular quarterly dividends); or

         (d) there shall be any capital reorganization or reclassification of
     the common stock (other than a change in par value or from par value to no
     par value or from no par value to par value of the common stock), or any
     consolidation or merger to which the Company is a party, or any sale or
     transfer of all or substantially all the assets of the Company; or

         (e) there shall be a voluntary or involuntary dissolution, liquidation
     or winding-up of the Company;

then, in any one or more of said cases, the Company shall give written notice to
the Warrant Holder, not

                                     E-28
<PAGE>
 
fewer than 20 days before any record date or other date set for definitive
action, or of the date on which such reorganization, reclassification, sale,
consolidation, merger, dissolution, liquidation or winding up shall take place,
as the case may be. Such notice shall also set forth such facts as shall
indicate the effect of such action (to the extent such effect may be known at
the date of such notice) on the current Exercise Price and the kind and amount
of the Warrant Shares and other securities and property deliverable upon
exercise of this Warrant. Such notice shall also specify the date as of which
the holders of the Common Stock of record shall be entitled to exchange their
Common Stock for securities or other property deliverable upon such
reorganization, reclassification, sale, consolidation, merger, dissolution,
liquidation or winding up, as the case may be.

entire interest is not being transferred or assigned, in the name of the Warrant

of this Warrant shall be without charge to the Warrant Holder and any new
Warrant or Warrants issued shall be dated the date hereof.  The term "Warrant"
as used herein includes any Warrants into which this Warrant may be divided or
for which it may be exchanged.

5.  Rights of Warrant Holder.  The Warrant Holder shall not, by virtue hereof,
    ------------------------                                                  
be entitled to any voting or other rights of a shareholder of the Company,
