ITEM 5. OTHER EVENTS.
 
I. NEW DIMENSION SOFTWARE LTD.
 
     A. TENDER AGREEMENT AND RELATED AGREEMENTS
 
     On March 8, 1999, BMC Software, Inc., a Delaware corporation (the
"Company"), issued a press release announcing the execution of a Share Purchase
and Tender Agreement, dated March 7, 1999 (the "Tender Agreement"), by and
between the Company and New Dimension Software Ltd., an Israeli corporation
("New Dimension"). Pursuant to the Tender Agreement, the Company will offer
$52.50 in cash (the "Offer Price") for each outstanding ordinary share, par
value NIS 0.01 per share (collectively, the "Shares"), of New Dimension in
accordance with the Offer (as defined therein). New Dimension has also agreed to
acquire and cancel all options to purchase shares of New Dimension and its
subsidiary for an amount in cash equal to the positive difference between the
Offer Price and the exercise price of such options, subject to adjustment in the
case of options to purchase shares of New Dimension's subsidiary. In addition,
the Company has agreed to issue stock options to purchase an aggregate of
500,000 shares of common stock of the Company to employees of New Dimension
after completion of the Offer. The Offer is conditioned upon, among other
things, there being validly tendered and not withdrawn prior to the expiration
of the Offer a number of Shares constituting at least 90% of the then issued and
outstanding Shares not owned by the Company and its subsidiaries (the "90%
Condition").
 
     If the Company is successful in acquiring through the Offer at least 90% of
the Shares not then owned by the Company or its subsidiaries within four months
of the date the Offer commences, the Company has agreed in the Tender Agreement,
in accordance with Section 236 of the Companies Ordinance (New Version) 5743-
1983 of the State of Israel, to declare by notice to the remaining shareholders
of New Dimension that it is unilaterally acquiring (the "Compulsory
Acquisition") the remaining Shares not yet held by it on the terms set forth in
the Offer.
 
     A description of the Tender Agreement is contained in the March 8, 1999
press release by the Company, filed herewith as Exhibit 99.1 and incorporated
herein by reference. The Tender Agreement is also filed herewith as Exhibit 2.1
and is incorporated herein by reference.
 
     In connection with the Offer contemplated by the Tender Agreement, the
Company entered into shareholder agreements, dated as of March 7, 1999 (the
"Shareholder Agreements"), with (i) Einav Computer Systems Ltd., an Israeli
corporation ("ECS"), and Roni A. Einav and Dalia Prashker-Katzman, the sole
shareholders of ECS, and (ii) Yossie Hollander (each a "Principal Shareholder"
and collectively, the "Principal Shareholders"). Pursuant to the Shareholder
Agreements, (a) the Principal Shareholders have agreed to tender into the Offer
all of their Shares, which, on the date of the Tender Agreement, represented an
aggregate of 7,482,500, or approximately 61%, of the issued and outstanding
Shares, (b) the Principal Shareholders have granted to the Company an
irrevocable option to purchase all of such Shares in certain circumstances, and
(c) each Principal Shareholder has granted to the Company an irrevocable proxy
to vote such Principal Shareholder's Shares with respect to matters relating to
the Tender Agreement, the Offer or matters inconsistent with the Offer. The
Shareholder Agreements are filed herewith as Exhibits 99.2 and 99.3 and are
incorporated herein by reference.
 
     As an inducement to the Company's execution of the Tender Agreement and
concurrently therewith, New Dimension agreed to enter into a third amendment
(the "Third Amendment") to the distribution agreement between New Dimension and
Boole & Babbage Europe, an Irish corporation ("Distributor") and a wholly owned
subsidiary of Boole & Babbage, Inc., a Delaware corporation ("Boole"), dated
October 28, 1994, as amended April 24 and October 31, 1997 (the "Distribution
Agreement"). The Third Amendment, effective as of March 6, 1999, excludes the
Offer from the provisions of the Distribution Agreement, which provides that a
"change of control" of New Dimension would provide the Distributor the right to
terminate the Distribution Agreement and receive a termination payment from New
Dimension. The Third Amendment is filed herewith as Exhibit 99.4 and is
incorporated herein by reference.
 
     In addition to the Third Amendment, the Company and New Dimension entered
into a letter agreement, dated March 7, 1999 (the "Letter Agreement"), which
provides that New Dimension will not exercise its right to terminate the
Distribution Agreement by reason of the Company's acquisition of Boole pursuant
to the
 
                                        1
<PAGE>   3
 
Agreement and Plan of Reorganization, dated October 31, 1998, by and between the
Company and Boole (the "Merger Agreement"), until April 10, 1999. The Letter
Agreement further provides that upon completion of the Company's acquisition of
Boole, the Company and the Distributor will enter into a fourth amendment (the
"Fourth Amendment") to the Distribution Agreement, which will provide for the
extension of the period during which New Dimension has the right to terminate
the Distribution Agreement as a result of the Company's acquisition of Boole
until December 31, 1999; provided, that New Dimension does not give notice of
its intent to terminate the Distribution Agreement in connection with the
Company's acquisition of Boole until the earlier of the day first succeeding (i)
the termination of the Offer or (ii) July 12, 1999, and that such termination
notice will become effective within 60 days of the receipt thereof by the
Distributor. The Letter Agreement is filed herewith as Exhibit 99.5 and is
incorporated herein by reference.
 
     B. FINANCING.
 
     The total amount of funds required by the Company to consummate the Offer
(including cash payments related to the cancellation of outstanding New
Dimension options) and the Compulsory Acquisition and to pay related fees and
expenses is estimated to be approximately $700 million.
 
     The consideration for the Shares to be purchased pursuant to the Offer and
the Compulsory Acquisition is expected to be funded from the Company's working
capital and loans from U.S. banks. The Company is currently negotiating with
three major commercial banks (the "Proposed Lenders") to obtain a credit
facility in an aggregate amount of $500,000,000 (the "Proposed Credit
Facility"). On March 10, 1999, the Company received commitments from each of the
Proposed Lenders, which are filed herewith as Exhibit 99.2 and are incorporated
herein by reference. The following is a summary of the principal terms of the
Proposed Credit Facility.
 
     The Proposed Credit Facility will consist of $500,000,000 of availability
under: (a) a 364-day revolving credit facility for general corporate purposes,
including the funding of the Offer, with renewal options by the Proposed Lenders
and with a one-year option granted to the Company, which will enable the Company
to convert the revolving loans into a one-year term loan, and (b) a competitive
bid facility which will enable the Company to request bids from the Proposed
Lenders for loans on a negotiated basis up to the existing availability under
the Proposed Credit Facility. If the Company elects to convert revolving
borrowings to a term loan, such term loan must be repaid within one year with
interest payable at specified margin levels above LIBOR.
 
     Interest rates for loans under the Proposed Credit Facility are based upon
a margin above LIBOR within current market parameters and certain financial
ratios of the Company.
 
     The Proposed Credit Facility will include, among others, covenants
regarding the maintenance by the Company of: (a) at least $300,000,000 in cash
and marketable securities and (b) certain financial ratios. The Proposed Credit
Facility will also contain other typical and customary covenants as well as
customary events of default.
 
     The Proposed Credit Facility requires the Company to pay an arrangement fee
on the aggregate commitment of the Proposed Lenders together with a facility fee
(ranging from 10 to 20 basis points) on the drawn and undrawn portion of the
aggregate commitments of the Proposed Lenders.
 
     Any loans under the Proposed Credit Facility will be repaid over time from
a variety of potential sources including, but not limited to, funds generated
internally by the Company and its subsidiaries. The Offer is not conditioned on
consummation of the Proposed Credit Facility.
 
     C. FINANCIAL INFORMATION
 
     The financial information provided in this Section C is being included in
this Form 8-K to provide additional information solely for the purpose of
illustrating how the New Dimension transaction might affect the Company and
Boole as a combined company from a financial point of view. The acquisition of
New Dimension is subject to numerous significant conditions, including the 90%
Condition. As a result of the 90% Condition, the acquisition of New Dimension by
the Company is uncertain. There can be no assurance that
 
                                        2
<PAGE>   4
 
the Company will succeed in its acquisition of New Dimension. The following
estimated financial information may not reflect the actual financial results of
the Company, Boole and New Dimension as a combined company. In addition, the
Company has made various assumptions in its preparation of these estimates.
These assumptions and estimated financial information consist of forward looking
statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"). These statements are identified as forward looking statements
in this discussion. Important factors, risks and uncertainties that could cause
the Company's, Boole's and New Dimension's actual results to differ materially
from the results implied by these forward looking statements are also discussed.
 
     1. SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION
 
     The unaudited pro forma financial information is derived from historical
financial information for the three companies, but includes assumptions and
adjustments to reflect the proposed combination of the three companies. The
descriptions of these assumptions and adjustments include forward looking
statements that contemplate future events, calculations or determinations. These
forward looking statements are subject to various risks and uncertainties that
could cause actual pro forma financial information for the three companies to
differ materially from those set forth below, including the following items:
 
     - Different Fiscal Year Ends. The fiscal year ends for the Company, Boole
       and New Dimension occur at different dates. The Company's fiscal year end
       is March 31, Boole's is September 30, and New Dimension's is December 31.
       In order to present the unaudited pro forma combined results on a
       comparable basis, certain adjustments were made to Boole's and New
       Dimension's results of operations for certain periods to conform to those
       of the Company. The selected unaudited pro forma condensed combined
       financial information for the years ended March 31, 1996 and 1997 are
       based on the consolidated financial statements of the Company for the
       years ended March 31, 1996 and 1997, Boole for the years ended September
       30, 1995 and 1996, and New Dimension for the years ended December 31,
       1995 and 1996. The selected unaudited pro forma condensed combined
       financial information for the year ended March 31, 1998 is based on the
       consolidated financial statements of the Company for the year ended March
       31, 1998; Boole for the year ended September 30, 1997 reduced by the
       unaudited consolidated statement of income of Boole for the six months
       ended March 31, 1997 and increased by the unaudited consolidated
       statement of income of Boole for the six months ended March 31, 1998; and
       New Dimension for the year ended December 31, 1998. The selected
       unaudited pro forma condensed combined financial information for the nine
       months ended December 31, 1997 and 1998 are based on the unaudited
       consolidated financial statements of the Company for the nine months
       ended December 31, 1997 and 1998; the consolidated financial statements
       of Boole for the years ended September 30, 1997 and 1998 reduced by the
       unaudited consolidated statements of income of Boole for the six months
       ended March 31, 1997 and 1998, respectively and increased by the
       unaudited consolidated statements of income of Boole for the three months
       ended December 31, 1997 and 1998, respectively; and the audited
       consolidated financial statements of New Dimension for the year ended
       December 31, 1997 and the unaudited consolidated financial statements for
       the year ended December 31, 1998 reduced by the unaudited consolidated
       financial statements of income of New Dimension for the three months
       ended March 31, 1997 and 1998, respectively. As a result of the
       adjustments to conform Boole's fiscal year end to the year ended March
       31, 1998, Boole's results of operations for the six months ended March
       31, 1997, which include total revenues of $96,212,000 and a net loss of
       $386,000 have not been included in the selected unaudited pro forma
       condensed combined statements of income for the periods presented. The
       unaudited pro forma condensed combined total assets amount is based on
       the balance sheets of the Company, Boole and New Dimension at December
       31, 1998.
 
     - Purchase Price. The unaudited pro forma financial information assumes a
       total purchase price for New Dimension of approximately $700 million,
       including transaction costs of approximately $15 million. The purchase
       price also includes approximately $2.26 million representing Boole's
       basis in approximately 452,800 shares of New Dimension common stock owned
       by Boole prior to the combination of the three companies. The shares of
       New Dimension common stock held by Boole are
                                        3
<PAGE>   5
 
reflected in Boole's unaudited historical financial information at current
market value which, as of December 31, 1998, approximated $48.125 per share. The
shares of New Dimension common stock held by Boole have been assumed to be owned
      by the Company prior to the tender offer, and therefore are not deemed to
      be outstanding as of the tender offer and not subject to the tender offer
      price of $52.50 per share for purposes of calculating the purchase price.
 
     - Purchase Price Allocation. The purchase price allocation for acquired
       in-process research and development is assumed to be approximately $132.3
       million, net of income taxes. The purchase price allocation for goodwill
       and other intangibles is assumed to be approximately $428 million.
       Amortization of goodwill and other intangibles is assumed to occur over a
       four year life, resulting in an annual noncash amortization expense of
       $70 million, net of income taxes, in each year following the acquisition.
       The final purchase price allocation will not be known until an
       independent appraisal is complete. The relative allocations of portions
       of the purchase price to acquired in-process research and development and
       the period over which goodwill and other intangibles will be amortized
       and the resulting amortization charge will be based upon determinations
       by the Company and its independent appraisers and will be subject to
       review by its auditors and by the Securities and Exchange Commission. The
       actual amount of any write-off of acquired in-process research and
       development, remaining amortized goodwill, the actual amortization period
       and the amount of annual amortization of goodwill and intangibles may
       vary significantly from these assumptions.
 
     - No Cost Savings or Revenue Enhancements. The unaudited pro forma
       financial information also does not reflect the effect of cost savings
       and revenue enhancements, if any, which may be realized after
       consummation of the transactions.
 
     - Elimination of Distributor Payments. The unaudited pro forma financial
       information eliminates distributor payments between Boole and New
       Dimension of $8.3 million, $11.3 million and $15.2 million for the years
       ended March 31, 1996, 1997 and 1998, respectively. The information also
       eliminates distributor payments between Boole and New Dimension of $10.5
       million and $10.1 million for the nine months ended December 31, 1997 and
       1998.
 
     - Interest. The unaudited pro forma financial information assumes interest
       expense related to short term borrowings of $500 million at 6.0% per
       annum and reduced interest income associated with the use of $176 million
       cash and investments with an approximate return of 6.0% per annum. These
       adjustments include assumptions about anticipated borrowing amounts, cost
       of funds and return on investment that could prove inaccurate.
 
     - Costs Associated with Proposed Combination of the Company and Boole. The
       unaudited pro forma financial information reflects an accrual, made only
       to the unaudited pro forma condensed combined balance sheet, of
       approximately $25.0 million (or $16.25 million, net of income taxes) for
       estimated transaction fees, certain identified restructuring charges and
       costs incident to the proposed merger between the Company and Boole.
       Actual results incurred in connection with the proposed merger could
       differ significantly from these estimates.
 
     - Conversion of Outstanding Shares of Boole's Common Stock. The unaudited
       pro forma financial information reflects the issuance of 0.675 of a share
       of the Company's common stock for each share of Boole common stock
       outstanding at December 31, 1998, pursuant to the terms of the Merger
       Agreement. Therefore, the historical combined common stock,
       paid-in-capital and retained earnings balances have been adjusted to
       reflect the number of shares assumed to be issued, the difference in par
       value per common share of the Company and Boole and the cancellation of
       Boole treasury stock. These adjustments are based on the historical
       outstanding share amounts. Actual shares outstanding on the date the
       proposed merger is consummated and, therefore, the actual impact of the
       conversion of outstanding shares of Boole's common stock on the
       historical combined common stock, paid-in-capital and retained earnings
       balances might differ from this estimate.
 
     The following table sets forth selected unaudited pro forma condensed
combined financial information derived from the historical financial information
of the Company, Boole and New Dimension and is based on
 
                                        4
<PAGE>   6
 
the assumptions and adjustments discussed above to reflect the expected
combination of the three companies. The unaudited pro forma combined income
statement data for the nine months ended December 31, 1997 and 1998 and for the
years ended March 31, 1996, 1997 and 1998 assume the merger with Boole and the
acquisition of New Dimension were both effected as of April 1, 1995. The
unaudited pro forma balance sheet data as of December 31, 1998 assumes the
merger with Boole and the acquisition of New Dimension were both effected as of
December 31, 1998.

     2. ANALYSIS OF IMPACT OF NEW DIMENSION TRANSACTION ON CERTAIN PRO FORMA
        ESTIMATES OF FUTURE FINANCIAL RESULTS
 
     The Company has prepared these calculations solely to illustrate the
estimated financial impact of the New Dimension transaction on the Company and
Boole as a combined company. If the New Dimension transaction is completed, the
Company expects the New Dimension transaction to close in the first or second
quarter of its March 31, 2000 fiscal year. The Company has made the following
assumptions in preparing the following pro forma financial information. These
assumptions and the pro forma financial information are forward looking
statements. Certain risks and uncertainties could cause the Company's future
operating results to differ materially from those indicated by any of these
forward looking statements, including those described below.
 
     - Revenue and Earnings Estimates of the Company and Boole are not Estimates
       by the Company or Boole and are Being Provided Solely for Illustrative
       Purposes. Combined earnings estimates for the Company and Boole for
       fiscal 2000 are based upon published financial estimates of SG Cowen &
       Co. dated January 25, 1999 for the Company and Boole on a combined basis.
       For fiscal 2001, the Company has assumed an earnings growth rate of 25%
       and applied this growth rate to the SG Cowen estimate for fiscal 2000.
       The use of the SG Cowen estimates and the assumed 25% growth rate are
       solely for the illustrative purpose of estimating the impact of the New
       Dimension transaction on the Company and Boole as a combined company. The
       Company is not adopting the SG Cowen estimates or the 25% fiscal 2001
       growth rate as accurate or indicative of the Company's internal
       estimates, nor is the Company giving guidance that it expects revenues,
       net earnings or earnings per share to equal or exceed these assumed
       amounts in fiscal 2000 or 2001.
 
     - New Dimension Revenue and Earnings Estimates are not Estimates by the
       Company or New Dimension and are Being Provided Solely for Illustrative
       Purposes. BMC and New Dimension are on different fiscal years. BMC's
       fiscal year ends on March 31, and New Dimension's ends on December 31. In
       preparing this analysis for BMC's fiscal year ending March 31, 2000 and
       2001, BMC has used estimates for New Dimension's fiscal year ending
       December 31, 1999 and 2000, respectively. This is consistent with the
       method of reconciling the two different fiscal year ends used in
       preparing the information provided above under the heading "Selected
       Unaudited Pro Forma Condensed Combined Financial Information." Earnings
       estimates for New Dimension's fiscal year ending December 31, 1999 and
       2000 are based upon published estimates of Goldman, Sachs & Co. dated
       February 24, 1999. The use of the Goldman, Sachs estimates are solely for
       the illustrative purpose of estimating the
 
                                        5

impact of the New Dimension transaction on the Company and Boole as a combined
company. The Company is not adopting the Goldman, Sachs estimates as accurate or
indicative of the Company's or New Dimension's internal estimates, nor is the
      Company giving guidance that it expects revenues, net earnings or earnings
      per share of New Dimension to equal or exceed these assumed amounts in
      fiscal 2000 or 2001.
 
     - Estimated Outstanding Shares are not Estimates by the Company and are
       Being Provided Solely for Illustrative Purposes. Estimated shares
       outstanding for fiscal 2000 are from the SG Cowen January 25, 1999
       report. Estimated shares outstanding for fiscal 2001 were calculated by
       increasing the fiscal 2000 amount by 4%. The Company is presenting these
       estimates solely for the purpose of this calculation. The amount of
       shares outstanding could be significantly increased by stock option
       grants, stock option exercises and acquisitions for stock, which increase
       the number of shares used to calculate earnings per share on a diluted
       basis.
 
     - Purchase Price Allocation; Amortization of Intangible Assets. The
       purchase price allocation for acquired research and development is
       assumed to be approximately $132.3 million, net of income taxes. The
       purchase price allocation for goodwill and other intangibles is assumed
       to be approximately $428 million. Amortization of goodwill and other
       intangibles is assumed to occur over a four year life, resulting in an
       annual noncash amortization expense of $70 million, net of income taxes,
       in each year following the acquisition. The net earnings and earnings per
       share amounts for fiscal 2000 and 2001 reflect amortization of intangible
       assets acquired in the New Dimension transaction. The net earnings and
       earnings per share amounts for fiscal 2000 reflect the anticipated
       write-off of acquired in-process research and development of
       approximately $132.3 million, net of income taxes. The net earnings and
       earnings per share amounts for fiscal 2000 and 2001 reflect the annual
       amortization of intangibles expense of $70 million, net of income taxes.
       Excluding these non-charges, the net earnings and earnings per share
       amounts in this presentation would be as follows:
 
        - The net earnings and earnings per share amounts for fiscal 2000
          excluding the anticipated write-off of acquired research and
          development would be $439 million and $1.69.
 
        - The net earnings and earnings per share amounts for fiscal 2000
          excluding the anticipated write-off of acquired research and
          development and amortization of intangibles would be $508 million and
          $1.95.
 
        - The net earnings and earnings per share amounts for fiscal 2001
          excluding the amortization of intangibles would be $644 million and
          $2.38.
 
       The final purchase price allocation will not be known until an
       independent appraisal is complete. The relative allocations of portions
       of the purchase price to acquired in-process research and development and
       the period over which goodwill and other intangibles will be amortized
       and the resulting amortization charge will be based upon determinations
       by the Company, its auditors and its independent appraisers and will be
       subject to review by the Securities and Exchange Commission. The actual
       amount of any write-off of acquired in-process research and development,
       remaining amortized goodwill, the actual amortization period and the
       amount of annual amortization of goodwill and intangibles may vary
       significantly from these assumptions.
 
     - Other Risks. The financial results and operations of the Company, Boole,
       and the Company and Boole as a combined company are subject to numerous
       risks and uncertainties including those set forth in the Company's
       Registration Statement on Form S-4 dated February 23, 1999 under the
       heading "Risk Factors" and additional risks and uncertainties applicable
       to the Company's financial results and operations set forth in the
       Company's Quarterly Reports on Form 10-Q and Annual Report on Form 10-K
       under the heading "Certain Risks and Uncertainties that Could Affect
       Future Operating Results."
 
     The following table sets forth certain pro forma estimates of future
financial results of the New Dimension transaction on the Company and Boole as a
combined company and is based on the assumptions and adjustments discussed
above. The data further assumes that the New Dimension transaction will close on
April 1, 1999.

II. NEW LITIGATION
 
     On March 9, 1999, a class action complaint was filed in the United States
District Court for the Southern District of Texas, Houston Division, styled
Rickey Hartman v. BMC Software, Inc., Max P. Watson, William M. Austin, M.
Brinkley Morse and Kevin Klausmeyer, No. B-99-0715, against the Company and four
senior executives of the Company alleging violations of Sections 10(b) and 20(a)
of the Exchange Act in connection with the Company's financial statement
presentation following its acquisition of BGS Systems, Inc. ("BGS") in March
1998 in a pooling-of-interests transaction. The lawsuit was filed following the
Company's announcement that it was restating its historical financial results to
include BGS's financial results in the Company's financial statements as a
condition to the Securities and Exchange Commission declaring effective the
Company's registration statement on Form S-4 for its pending acquisition of
Boole. The complaint alleges that the Company and the individual defendants
artificially inflated the Company's stock price by failing to include the
historical results of BGS in the Company's historical financial statements
thereby reporting inflated revenue and income growth rates during the first
three quarters of fiscal 1999 ended December 31, 1998. The plaintiffs seek an
unspecified amount of compensatory damages, interest and costs, including legal
fees.
 
     The Company denies the allegations of wrongdoing in connection with the
matters set forth in the complaint and intends to vigorously defend the action.
An unfavorable judgment or settlement, however, could have a material adverse
effect on the financial results of the Company.

                       SHARE PURCHASE AND TENDER AGREEMENT

         THIS SHARE PURCHASE AND TENDER AGREEMENT is dated as of March 7, 1999
by and between New Dimension Software Ltd., an Israeli corporation (the
"Company"), and BMC Software, Inc., a Delaware corporation ("Purchaser").

                                    RECITALS

         WHEREAS, the respective Boards of Directors of the Company and
Purchaser have approved the acquisition of the Company by Purchaser, upon the
terms and subject to the conditions set forth herein;

         WHEREAS, the Board of Directors of the Company deems it desirable and
in the best interests of the Company and its shareholders that the Company enter
into this Agreement which provides for a cash tender offer for Shares (as
defined below) pursuant to Section 236 of the Companies Ordinance (New Version)
5743-1983 of the State of Israel (the "Companies Ordinance"), whereby, among
other things, all of the issued and outstanding ordinary shares, par value NIS
0.01 per share, of the Company ("Shares") that are validly tendered pursuant to
such offer, shall be purchased by Purchaser in exchange for an amount of cash
equal to the Per Share Amount (defined below), upon the terms and subject to the
conditions set forth herein and in accordance with the laws of the State of
Israel;

         WHEREAS, Purchaser is unwilling to enter into this Agreement (and
effect the transactions contemplated hereby) unless, contemporaneously with the
execution and delivery hereof, certain beneficial and record holders of the
Shares enter into Shareholder Agreements under which such holders have, among
other things, agreed to tender their Shares into the Offer (the "Shareholder
Agreements") and, in order to induce Purchaser to enter into this Agreement,
such holders are executing and delivering concurrently herewith the Shareholder
Agreements;

         WHEREAS, as a material inducement for Purchaser to enter into this
Agreement, the Company has agreed to amend the Distribution Agreement dated
October 26, 1997, as previously amended, between the Company and Boole & Babbage
Europe effective as of the date of this Agreement; and

         WHEREAS, as a condition to entering into this Agreement, Purchaser has
required the Company to settle all claims with members of its Board of Directors
for a maximum settlement amount and, as part of such requirement, certain
directors of the Company have agreed to release all claims against the Company
relating to their relationship with the Company prior to the Closing Date (as
defined below) pursuant to those certain Releases dated as of the date of this
Agreement (the "Director Releases"); and

         NOW, THEREFORE, in consideration of the foregoing and of the respective
representations, warranties, covenants and agreements set forth in this
Agreement, the parties hereto hereby agree as follows:

                                    ARTICLE I
                                    THE OFFER

         1.1. The Offer.

         (a) As promptly as practicable (but in no event later than five
business days following the public announcement of the execution hereof),
Purchaser shall commence (within the meaning of Rule 14d-2 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), an offer to purchase all
of the Company's outstanding Shares, at a price of $52.50 per Share (as such
amount may be increased, the "Per Share Amount"), net to the seller in cash (as
such offer may be amended in accordance with the terms of this Agreement, the
"Offer"), subject to the conditions set forth in Exhibit A hereto and all
provisions under the laws and regulations of the State of Israel.
Notwithstanding the foregoing, the directors of the Company will not have the
right to tender their Shares unless the Company's shareholders shall have
approved such right in accordance with Section 1.2(b). If, between the date of
this Agreement and the date on which Shares are accepted for payment pursuant to
the Offer (the "Closing Date"), the outstanding Shares are changed into a
different number or class of shares by reason of any stock split, stock
dividend, reverse stock split, reclassification, recapitalization or other
similar transaction, then the Per Share Amount shall be appropriately adjusted.
Purchaser expressly reserves the right to amend or modify the terms of the Offer
at any time prior to acceptance of Shares for payment pursuant to the Offer,
except that the Purchaser shall not, without the prior written consent of the
Company, (i) decrease or change the form of the consideration payable in the
Offer, (ii) impose additional conditions to the Offer, (iii) change the
conditions to the Offer, except that Purchaser in its sole discretion may waive
any of the conditions to the Offer, or (iv) make any other change in the terms
or conditions of the Offer that is adverse to the holders of Shares. Purchaser
will, on the terms and subject to the prior satisfaction or waiver of the
conditions to the Offer, accept for payment and pay for all Shares validly
tendered and not withdrawn pursuant to the Offer promptly after expiration of
the Offer. The Offer shall be open for an initial period of 20 business days
from the date of commencement thereof; provided that, Purchaser may, in
accordance with applicable law, extend the Offer if the conditions to the Offer
have not been satisfied. The Company agrees that no Shares held by the Company
will be tendered to Purchaser pursuant to the Offer; provided, that Shares held
beneficially or of record by any plan, program or arrangement sponsored or
maintained for the benefit of employees of the Company shall not be deemed to be
held by the Company, regardless of whether the Company has, directly or
indirectly, the power to vote or control the disposition of such Shares. The
obligations of Purchaser to commence the Offer and to accept for payment and to
pay for Shares validly tendered on or prior to the expiration of the Offer and
not withdrawn shall be subject only to the conditions set forth in Exhibit A
hereto. As long as the Company or its Board of Directors shall not have asserted
any of their rights pursuant to Section 5.8(b), Purchaser shall at the request
of the Company extend the Offer if at any scheduled expiration date of the Offer
any of the conditions to Purchaser's obligations to purchase Shares shall not be
satisfied; provided, however, that Purchaser shall not be required to extend the
Offer beyond July 12, 1999.

         (b) On the date of commencement of the Offer, Purchaser shall file with
the Securities and Exchange Commission (the "SEC") a Tender Offer Statement on
Schedule 14D-1 (together with all amendments thereto, the "Schedule 14D-1") with
respect to the Offer, which shall contain the offer to purchase and related
letter of transmittal and other ancillary offer documents and instruments

                                       -2-
 

<PAGE>   7




pursuant to which the Offer will be made (collectively, together with any
supplements or amendments thereto, the "Offer Documents"). Purchaser will
disseminate the Offer Documents to holders of Shares. Each of Purchaser and the
Company will promptly correct any information provided by it for use in the
Offer Documents that becomes false or misleading in any material respect and
Purchaser will take all steps necessary to cause the Offer Documents as so
corrected to be filed with the SEC and to be disseminated to holders of Shares,
in each case as and to the extent required by applicable law. The Company and
its counsel shall be given a reasonable opportunity to review and comment on the
Offer Documents prior to their filing with the SEC. Purchaser agrees to provide
the Company with any comments that may be received from the SEC or its staff
with respect to the Offer Documents promptly after receipt thereof and to
further provide the Company with a reasonable opportunity to participate in all
substantive communications with the SEC and its staff relating to the Offer
Documents, the Offer or the transactions contemplated thereby.

         1.2. Company Actions.

         (a) The Company hereby consents to the Offer and represents and
warrants that its Board of Directors (at a meeting or meetings duly called and
held) has (a) unanimously determined as of the date hereof that the Offer is
fair to and in the best interests of the shareholders of the Company and (b)
resolved, subject to the directors of the Company not having the right to tender
their Shares or the right to receive any compensation for services provided to
the Company pursuant to the Director Releases, unless the Company's shareholders
shall have approved such right in accordance with Section 1.2(b), to recommend
acceptance of the Offer and approval of the matters set forth in Section 1.2(b)
by the shareholders of the Company. The Company further represents that CIBC
Oppenheimer Corp. has rendered to the Board of Directors of the Company its
opinion, dated as of the date hereof, to the effect that the Per Share Amount is
fair to the holders of the Shares from a financial point of view. As soon as
practicable after the commencement of the Offer, the Company shall file or cause
to be filed with the SEC a Solicitation/Recommendation Statement on Schedule
14D-9 (the "Schedule 14D-9") containing the unanimous recommendation of the
Board of Directors in favor of the Offer and shall permit the inclusion in the
Schedule 14D-1 of such recommendation. Each of the Company and Purchaser will
promptly correct any information provided by it for use in the Schedule 14D-9
that becomes false or misleading in any material respect and the Company will
take all steps necessary to cause the Schedule 14D-9 as so corrected to be filed
with the SEC and to be disseminated to holders of Shares, in each case as and to
the extent required by applicable law. Purchaser and its counsel shall be given
a reasonable opportunity to review and comment on the Schedule 14D-9 prior to
its filing with the SEC. The Company agrees to provide Purchaser with any
comments that may be received from the SEC or its staff with respect to the
Schedule 14D-9 promptly after receipt thereof and to further provide Purchaser
with a reasonable opportunity to participate in all substantive communications
with the SEC and its staff relating to the Schedule 14D-9, the Offer or the
transactions contemplated thereby.

         (b) The Company agrees, as soon as practicable after the date of this
Agreement, to duly call, give notice of, convene and hold an extraordinary
general meeting of its shareholders (the "Special Meeting") for the purpose of
submitting for approval by the Company's shareholders proposals to (i) approve
the right of the directors of the Company to sell their Shares to the Purchaser
pursuant to the Offer and the transactions contemplated thereby and the right to
receive any compensation for services provided to the Company from the Company
pursuant to the Director

                                       -3-
 

<PAGE>   8




Releases, and (ii) approve, by special resolution, an amendment to the Company's
Articles of Association to provide that the holders of at least 60% of the
issued and outstanding Shares of the Company shall be entitled to appoint and
remove any and all members of the Board of Directors of the Company, by means of
a written notice signed by such holders to the Company (collectively, the
"Shareholder Approvals"). The Company further agrees to use its best efforts to
solicit proxies in favor of and to take all other actions necessary to obtain
the Shareholder Approvals at the Special Meeting. The amendment to the Articles
of Association shall be in the form attached hereto as Exhibit 1.2(b). The
Company will provide Purchaser with a reasonable opportunity to review and
approve all proxy or other materials to be sent to shareholders in connection
with the Special Meeting.

         1.3. Shareholder Lists. In connection with the Offer, the Company shall
promptly furnish or cause to be furnished to Purchaser mailing labels and
security position listings and any available listing or computer file containing
the names and addresses of the record holders of Shares as of a recent date and
shall furnish Purchaser with such information reasonably available to the
Company and such assistance as Purchaser or its agents may reasonably request in
communicating the Offer to the record and beneficial holders of Shares. Subject
to the requirements of applicable law and except for such steps as are necessary
to disseminate the Offer Documents and any other documents necessary to
consummate the Offer, Purchaser and its affiliates will hold in confidence such
listings and other information, shall use such information only in connection
with the Offer and, if this Agreement is terminated, shall, and shall cause its
agents or other representatives to, promptly deliver to the Company all copies
of all such information (and extracts or summaries thereof) then in their
possession.

         1.4. Directors. Subject to obtaining the Shareholder Approvals,
promptly upon the purchase by Purchaser pursuant to the Offer of such number of
Shares as represents at least 60% of the outstanding Shares and from time to
time thereafter, Purchaser shall be entitled to designate the entire Board of
Directors of the Company, and the Company shall, upon request of Purchaser, take
all actions necessary to enable such Purchaser designees to be so elected or
appointed.

                                   ARTICLE II
                     OTHER AGREEMENTS RELATING TO THE OFFER

         2.1. Options and Other Purchase Rights.

         (a) The Company shall use its best efforts to obtain from each holder
of options ("Company Options") granted under the stock option plans of the
Company or any subsidiary of the Company ("Company Option Plans") an agreement
in the form of Exhibit B hereto pursuant to which on the Closing Date the
Company will cancel such Company Options and make the payments described below.
On the Closing Date, each Company Option for which an agreement from the holder
thereof has been obtained pursuant to this Section 2.1(a) that is outstanding
immediately prior to the Closing Date, whether or not then exercisable or
vested, will be canceled by the Company effective on the Closing Date, and the
holders thereof shall be entitled to receive, for each Share subject to such
Company Option, in settlement and cancellation thereof, an amount in cash equal
to the positive difference, if any, between the Per Share Amount and the
exercise price per share of such Company Option, which amount shall be paid by
the Company at the time the Company Option

                                       -4-
 

<PAGE>   9




is canceled; provided, however, that for purposes of calculating the amount of
cash to be paid in respect of the cancellation of Company Options that are
options to purchase shares of EagleEye Control Software Ltd. capital stock
rather than Shares of the Company, the Per Share Amount used in the foregoing
calculation shall be multiplied by 9.085. All applicable withholding taxes
attributable to the payments made hereunder or to distributions contemplated
hereby shall be deducted from the amounts payable under this Section 2.1(a) and
all such taxes attributable to the cancellation of Company Options shall be
withheld from the proceeds received in connection with the cancellation thereof.

         (b) To the extent permitted by the Company Option Plans, the Company
Option Plans shall terminate on the Closing Date and any rights under any
provisions in any other plan, program or arrangement providing for the issuance
or grant by the Company of any interest in respect of the capital stock of the
Company shall be canceled as of the Closing Date.

         (c) Purchaser shall make available to the Company all funds required to
make the payments to the holders of Company Options as set forth in Section
2.1(a) above.

         2.2. Compulsory Acquisition. If Purchaser is successful in acquiring
pursuant to the Offer at least 90% of the Shares not owned by Purchaser or its
subsidiaries within four months after the date the Offer commences (the "Initial
Period"), Purchaser shall, pursuant to Section 236 of the Companies Ordinance,
declare by notice to the remaining shareholders (the "Notice of Acquisition")
that it is unilaterally acquiring (the "Compulsory Acquisition") the remaining
Shares not yet held by it on the same terms as those set forth in the Offer. The
Notice of Acquisition will be delivered at any time during the two month period
following the Initial Period. The Offer will serve as a "Plan" or "Contract"
under Section 236 of the Companies' Ordinance.

         2.3. Reservation of Right to Revise Structure. At Purchaser's election,
the Offer may alternatively be structured so that the issued and outstanding
Shares transferred to Purchaser shall be transferred to a newly formed, wholly
owned subsidiary of Purchaser provided that no such change shall alter or change
the Per Share Amount. In the event of such an election by Purchaser, the parties
agree to execute the appropriate documents to reflect such an election.

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES
                                 OF THE COMPANY

         The Company represents and warrants subject to the exceptions
specifically described in writing in the respective sections of the disclosure
schedule delivered by the Company to Purchaser and dated the date hereof (the
"Company Disclosure Schedule") as follows:

         3.1. Organization and Standing. The Company is a corporation duly
organized, validly existing under the laws of the State of Israel, has full
requisite corporate power and authority to carry on its business as it is
currently conducted, and to own and operate the properties currently owned and
operated by it, and is duly qualified or licensed to do business and is in good
standing as a foreign corporation authorized to do business in all jurisdictions
in which the character of the properties owned or the nature of the business
conducted by it would make such qualification or


                                       -5-
 

<PAGE>   10




licensing necessary, except where the failure to be so qualified or licensed
would not reasonably be expected to have a Material Adverse Effect.

         3.2. Agreement Authorized and its Effect on Other Obligations. The
consummation of the transactions contemplated hereby have been duly and validly
authorized by all necessary corporate action on the part of the Company other
than the Shareholder Approvals, and this Agreement is a valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms, except as enforceability may be limited by (i) bankruptcy, insolvency,
reorganization, debtor relief or similar laws affecting the rights of creditors
generally, and (ii) general principles of equity. The purchase of Shares
pursuant to the Offer will not conflict with or result in a violation or breach
of any term or provision of, nor constitute a default under, (i) the Memorandum
of Association or Articles of Association of the Company or (ii) any indenture,
mortgage, deed of trust, lease, contract or other agreement to which the Company
or any of its subsidiaries is a party or by which the Company or any of its
subsidiaries or their properties are bound, other than such violations, breaches
or defaults as would not reasonably be expected to have a Material Adverse
Effect. Section 3.2 of the Company Disclosure Schedule lists all holders of any
material indebtedness for borrowed money of the Company as of the date of this
Agreement, the lessors of any material property leased by Company and the other
parties to any Material Contract (as defined in Section 3.9) to which Company is
a party as of the date of this Agreement in each case whose consent to the Offer
or the Compulsory Acquisition is required.

         3.3. Capitalization. The authorized capitalization of the Company
consists of 20,000,000 ordinary shares, par value NIS 0.01 per share, of which
as of the date hereof 12,258,898 Shares were issued and outstanding, and an
additional 950,705 Shares were reserved for issuance in conjunction with various
employee benefit plans. All of such outstanding shares are validly issued, fully
paid and nonassessable, and were not issued in violation of any preemptive
rights of any shareholder. Section 3.3 of the Company Disclosure Schedule sets
forth a complete list as of the date of this Agreement of all outstanding
options, warrants or obligations of any kind to issue any shares of capital
stock of Company or any subsidiary thereof, the owners thereof and the amounts
owned.

         3.4. Subsidiaries. Section 3.4 of the Company Disclosure Schedule lists
the subsidiary corporations of the Company existing as of the date hereof, and
shows as to each of such subsidiary corporations the percentage of the total
outstanding stock thereof which is owned by the Company at such date. All
outstanding shares of stock of the subsidiary corporations owned by the Company
are validly issued, fully paid, and nonassessable, and the Company has good and
valid title thereto free and clear of any mortgage, pledge, lien, charge,
security interest, option, right of first refusal, preferential purchase right,
defect, encumbrance or other right or interest of any other person
(collectively, an "Encumbrance"), except for shares of capital stock or other
similar ownership interests of certain subsidiaries of the Company that are
owned by certain nominee equity holders as required by the applicable law of the
jurisdiction of organization of such subsidiaries. Each such subsidiary is a
corporation duly organized, validly existing, and in good standing (or
equivalent concept with respect to jurisdictions that do not recognize such
concept) under the laws of the jurisdiction under which it is incorporated and
has full requisite corporate power and authority to own its property and carry
on its business as presently conducted by it and is, or on the Closing Date will
be, duly qualified or licensed to do business and is, or on the Closing Date
will be, in good standing (or equivalent concept with respect to jurisdictions
that do not recognize such concept) as


                                       -6-
 

<PAGE>   11




a foreign corporation authorized to do business in all jurisdictions in which
the character of the properties owned or the nature of the business conducted by
such subsidiary makes such qualification or licensing necessary, except where
the failure to be so qualified or licensed would not reasonably be expected to
have a Material Adverse Effect on the Company. As hereinafter used in this
Article III, the term "Company" also includes any and all of its directly and
indirectly held subsidiaries, except where the context indicates to the
contrary; provided, however, that for purposes of Sections 3.7(a) and 3.18, the
term "Company" further includes any corporation, trade, business or entity under
common control with the Company within the meaning of Section 414(b), (c), (m)
or (o) of the Internal Revenue Code of 1986, as amended (the "Code") or Section
4001 of ERISA.

         3.5. Reports and Financial Statements.

         (a) The Company has previously furnished to Purchaser true and complete
copies of (a) all annual reports filed by Company with the SEC pursuant to the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), since December

(c) any registration statements (other than Form S-8s) of Company declared
effective by the SEC since December 31, 1995. The consolidated financial
statements of Company and its subsidiaries included in the Company's most recent
report on Form 20-F and any other reports filed with the SEC by the Company
under the Exchange Act subsequent thereto (collectively, the "Company Reports")
were, or (if filed after the date hereof) will be, prepared in accordance with
United States generally accepted accounting principles applied on a consistent
basis during the periods involved and fairly present, or will fairly present,
the consolidated financial position for Company and its subsidiaries as of the
dates thereof and the consolidated results of their operations and changes in
financial position for the periods then ended (except with respect to interim
period financial statements, for normal year-end adjustments which are not
material and for the absence of footnotes). The Company Reports did not at the
time each of the Company Reports was filed with the SEC (or, if amended or
superseded by a subsequent filing, then on the date of such filing), and (if
filed after the date hereof) will not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under whey they
were made, not misleading. Since December 31, 1995, the Company has filed with
the SEC all reports required to be filed by the Company under the Exchange Act
and the rules and regulations of the SEC.

         (b) Included in Section 3.5(b) of the Company Disclosure Schedule are
preliminary unaudited consolidated financial statements of the Company and its
subsidiaries for the year ended December 31, 1998 (the "1998 Preliminary
Statements"). As soon as they become available and prior to the Closing Date,
the Company will deliver to the Purchaser audited financial statements of
Company and its subsidiaries for the year ended December 31, 1998 (the "1998
Audited Statements"). The 1998 Preliminary Statements were, and the 1998 Audited

accounting principles applied on a consistent basis during the periods involved
and fairly present, or will fairly present, the consolidated financial position
for Company and its subsidiaries as of the date thereof and the consolidated
results of their operations and changes in financial position for the period
then ended. Except as set forth in Section 3.5(b) of the Company Disclosure
Schedule, the 1998 Preliminary Statements and the 1998 Audited Statements will
not differ in any material respect.

disclosed in the consolidated financial statements of Company prepared in

on a consistent basis, except for: (i) liabilities disclosed in the financial

entitled to any benefit of the type described in this Section 3.11(l).

         3.12. Intellectual Property. For purposes of this Section 3.12 and
Section 3.13, "Third Party Distributed Software" means the third party software
programs currently being distributed by the Company, whether as integrated or
bundled with any of the Company's software products or as a separate stand-alone
product, and "Internally Developed Software" means all software programs
developed for or on behalf of the Company and currently being distributed by the
Company and all software products or programs under development by the Company
but not currently distributed, other than Third Party Distributed Software.
Third Party Distributed Software and Internally Developed Software shall
collectively be referred to as the "Software Programs."

         (a) Ownership. The Company exclusively owns all Internally Developed
Software, including without limitation those Software Programs listed on Section
3.12(a) of the Company Disclosure Schedule, free and clear of all mortgages,
pledges, liens, security interests, conditional sales agreements, encumbrances
or charges of any kind (other than object code end-user licenses in the ordinary
course of business and Marketing Agreements (as defined below)). The Company
exclusively owns all material patents, trademarks, service marks, trade names
and copyrights (including registrations, licenses and applications pertaining
thereto) and all other material intellectual property rights, trade secrets and
other confidential or proprietary information, processes and formulae embodied
in the Internally Developed Software (the "Intellectual Property"), free and

agreements, encumbrances or charges of any kind (other than object code end-user
licenses in the ordinary course of business and Marketing Agreements). Section

<PAGE>   16




         (b) Notices. In no instance has the eligibility of the Internally
Developed Software for protection under applicable copyright law been forfeited
to the public domain by omission of any required notice or any other action.

         (c) Protection. The source code and related technical system
documentation for the Internally Developed Software are protected by the Company
as trade secrets in accordance with trade secret protections sufficient to
maintain trade secret status under applicable law. Except as set forth in
Section 3.12(c) of the Company Disclosure Schedule, the source code and related
technical system documentation for the Internally Developed Software have been
disclosed by the Company only to (i) employees and contractors who have had a
"need to know" the contents thereof in connection with the performance of their
duties to the Company and who have executed nondisclosure agreements
substantially in the form provided by the Company to Purchaser, and (ii) third
parties under source code escrow agreements.

         (d) Personnel. The Company has maintained a policy in accordance with
customary software industry standards whereby its personnel who during the three
years prior to the date hereof have been employees, agents, consultants and
contractors of the Company and who (on behalf of the Company) have contributed
to or participated in the conception and development of Internally Developed
Software and related technical documentation that is material to the operation
of the Company's business have executed nondisclosure and noncompetition
agreements substantially in the form provided by the Company to Purchaser. All
personnel who have contributed to or participated in the conception or
development of Internally Developed Software have no rights to any such

Section 3.12(e) of the Company Disclosure Schedule lists all license agreements
for the use of all such material Third Party Software and, if any such software
is not licensed, the basis of the use of such software by the Company. The
Company has not taken any action that could, or failed to take any action, the
failure of which could, reasonably be expected to (i) give rise to the
termination by a licensor of the Company's license to distribute any material
Third Party Distributed Software or (ii) materially restrict the Company's right
of use of any material Third Party Distributed Software under any license
agreement or other right of use, in each case subject to any right Company may
have to receive notice of and/or cure or remedy such action or failure to act.

         (f) No Infringement. The Internally Developed Software and, to the
Company's knowledge as of the date of this Agreement, the Third Party
Distributed Software do not infringe and will not infringe any copyright or
trade secret of any person or entity, and, to the Company's knowledge, no part
of the Internally Developed Software nor the use thereof for their intended
purposes (and to the Company's knowledge as of the date of this Agreement, no
part of the Third Party Distributed Software nor the use thereof for their
intended purposes) infringes or will infringe any valid and subsisting patent or
other exclusionary right of any third party. As of the date of this Agreement,
no written claims have been asserted against the Company by any person or entity
as to the use of any of the Intellectual Property.

<PAGE>   17




         (g) Integrity. Except with respect to demonstration or trial copies, no
portion of the Internally Developed Software or, to the Company's knowledge as
of the date of this Agreement, the Third Party Distributed Software contains any
"back door," "time bomb," "Trojan horse," "worm," "drop dead device," "virus" or
other software routines or hardware components designed to permit unauthorized
access or to disable or erase software, hardware, or data without the consent of
the user.

         (h) Year 2000 Compliance. All Software Programs designated with a
"check" in the table (the "Y2K Compliance Table") with the heading "B. Release
Information" at the third through sixth pages of Exhibit 3.12(h) to the Company
Disclosure Schedule are Year 2000 Compliant. All Software Programs that are not
designated with a "check" as currently being Year 2000 Compliant will be Year
2000 Compliant on the date indicated in the Y2K Compliance Table. As used in
this Section 3.12(h), "Year 2000 Compliant" means such Software Programs will
handle correctly:

         o        storage and retrieval of date values

         o        arithmetic calculations which involve date values

         o        comparison and sorting of date fields

         o        calendar management

         o        execution in the 20th and 21st centuries, and real time
                  transition from the former to the latter

         o        common and concurrent manipulation of date values from both
                  the 20th and the 21st century

         o        unambiguous association of any 2-digit year value with a
                  century value

         o        avoidance of extended semantics. All values (including "00"
                  and "99") in any year- field represent only the associated
                  year

"Year 2000 Compliant" further means such Software Programs:

         o        will manage and manipulate data involving dates, including
                  single-century formulas and multi-century formulas and not
                  cause an abnormally ending scenario within the application or
                  result in the generation of incorrect values involving such
                  dates

         o        ensure that all date-related user interface functionality and
                  data fields include the indication of century

         o        ensure that all date-related functions will include the
                  indication of century.

         (i) Notification. The Company has notified each of its customers
(excluding customers licensed through distributors) which releases of the
Software Programs licensed by such customer will and will not be Year 2000
Compliant.

         (j) Migration Path. The implementation of the Year 2000 Compliant
version of each Software Program will be independent of the version of the
Software Program from which the customer is migrating.

         3.13. Software Contracts.

         (a) End-User Agreements. Section 3.13(a) of the Company Disclosure
Schedule sets forth a complete example of each of the Company's current standard
end user license agreements with respect to the Internally Developed Software
(the "Standard Licenses"). Section 3.13(a) of the Company Disclosure Schedule
accurately identifies each license transaction (with customer name redacted if
desired) which generated $200,000 (or the equivalent in foreign currency) or
more of revenues for the Company during the fiscal year ended December 31, 1998.

         (b) Marketing Agreements. Section 3.13(b) of the Company Disclosure
Schedule sets forth a complete list of all contracts, agreements, licenses, or
other commitments or arrangements in effect with respect to the marketing,
remarketing, distribution, licensing or promotion of the Software Programs or
any other technical documentation or the Intellectual Property by any
independent salesperson, distributor, sublicensor or other remarketer or sales
organization (the "Marketing Agreements"), which generated 5% or more of the
Company's revenues during the preceding four fiscal quarters.

         3.14. Title to Properties. With minor exceptions, which in the
aggregate are not material, and except for merchandise and other property and
assets sold, used or otherwise disposed of in the ordinary course of business
for fair value or no longer necessary for the operation of the Company's
business, the Company has good and valid title to or valid leasehold interests
in all its properties, interests in properties and assets, real and personal,
reflected in the most recent balance sheet of the Company included in the
Company Reports, free and clear of any Encumbrance of any nature whatsoever,
except (i) liens and Encumbrances reflected in the most recent balance sheet of
the Company included in the Company Reports, (ii) liens for current taxes or
other governmental charges or levies not yet due and payable, (iii) Encumbrances
that are created, arise or exist under or in connection with any leases or other
contracts or other matters referred to in the Company Disclosure Schedule, (iv)
Encumbrances that relate to or are created, arise or exist in connection with,
any legal proceeding that is being contested in good faith, and (v) such
imperfections of title, easements and Encumbrances, if any, as do not and will
not materially detract from the value of the property subject thereto or
affected thereby, or otherwise materially impair business operations. All leases
pursuant to which the Company leases (whether as lessee or lessor) any
substantial amount of real or personal property are in good standing, valid and
effective, except as validity or effectiveness may be limited by (i) bankruptcy,
insolvency, reorganization, debtor relief or similar laws affecting the rights
of creditors generally, and (ii) general principles of equity; and there is not,
under any such leases, any existing or prospective default or event of default
or event which with notice or lapse of time, or both, would constitute a default
by the Company and in respect to which the Company has not taken reasonable
steps to prevent a default from occurring. The buildings and premises of the
Company that are used in its business are in good and sufficient operating
condition and repair for the continued conduct of the Company's business on a
basis consistent with past practice, subject to ordinary wear and tear. All
major items of equipment of the Company are in good and sufficient operating
condition and in a state of reasonable maintenance and repair for the continued
conduct of the Company's business on a basis consistent with past practice,
ordinary wear and tear excepted, and are free from any known defects except as
may be repaired by routine maintenance and such minor defects as do not
substantially interfere with the continued use thereof in the conduct of normal
operations.

other rights and privileges ("Permits") necessary in order for it to carry on
its business as presently conducted, except such Permits which no governmental
authority has demanded be obtained, or of which the company is unaware, or which

proposal which constitutes, or may reasonably be expected to lead to, any
acquisition or purchase by a third party (other than Purchaser or an affiliate
of Purchaser) of a substantial amount of assets of, or any equity interest in,
the Company or any merger, consolidation, business combination, sale of
securities, recapitalization, liquidation, dissolution or similar transaction
involving the Company (collectively, "Company Transaction Proposals") or agree
to or endorse any Company Transaction Proposal or (ii) propose, enter into or
participate in any discussions or negotiations regarding any Company Transaction

Proposal, taking and disclosing to its shareholders a position (including a
positive recommendation) with respect thereto or changing, withdrawing or
withholding the approval or recommendation by the Company's Board of Directors
of the Offer, but in each case referred to in the foregoing clauses (i) through
(iii) only after the Board of Directors of the Company concludes in good faith
following advice of its independent counsel, evidenced by a written opinion,

to comply with its fiduciary obligations to the Company's shareholders under
applicable Israeli law. If the Board of Directors of the Company receives a

Transaction Proposal that the Board of Directors of the Company determines in
good faith after consultation with (and based in part on the advice of) its
independent financial advisors to be more favorable to the Company and the
Company's shareholders than the Offer, which Company Transaction Proposal is not
subject to any material contingencies relating to financing.

Section 6.1(e)(ii) hereof or by the Company pursuant to Section 6.1(f) hereof,

party (other than Purchaser or an affiliate of Purchaser) a proposal for an
Alternative Company Transaction (as defined below); (B) the Offer is terminated
or expires as a result of the failure of a condition specified in Exhibit A
hereto; and (C) either the Company's Board of Directors recommends or approves
an acquisition agreement which provides for an Alternative Company Transaction
or an Alternative Company Transaction is consummated, in each case with any
third party which after the date of this Agreement and before termination of
this Agreement has publicly announced a proposal for Alternative Company
Transaction, in either case prior to twelve months after the date of termination
of this Agreement, then, in any such event unless this Agreement has been
terminated by the Company pursuant to Section 6.1(h), the Company shall pay to
Purchaser simultaneously with termination by the Purchaser in the case of the
occurrence of any of the events specified in clause (i) above, and immediately
upon the first to occur of the entering into an agreement providing for, or the
consummation of, an Alternative Company Transaction in the case of clause (ii)
above (by wire transfer of immediately available funds to an account designated
by Purchaser for such purpose), a fee (the "Break-Up Fee") in an amount equal to
$25.0 million. For purposes of this Paragraph 5.8(c), the term "Alternative
Company Transaction" shall mean any transaction pursuant to which (i) any
person, entity or group (within the meaning of Section 13(d)(3) of the Exchange
Act) (other than Purchaser or any affiliate of Purchaser) (each, a "Third
Party") acquires 50% or more of the outstanding Shares, (ii) a Third Party
acquires 25% or more of the total assets of the Company taken as a whole, (iii)
a Third Party merges, consolidates or combines in any other way with the Company
other than in a transaction in which holders of Shares continue to own at least
75% of the equity of the surviving corporation, or (iv) the Company distributes
or transfers to its shareholders, by dividend or otherwise, assets constituting
25% or more of the market value or earning power of the Company on a
consolidated basis (it being understood that stock of subsidiaries constitute
assets of the Company for purposes of this Paragraph 5.8(c)).

         5.9. D&O Indemnification.

         (a) From the Closing Date through the later of (i) the sixth
anniversary of the Closing Date and (ii) the expiration of any statute of
limitations applicable to any claim, action, suit, proceeding or investigation
referred to below, the Company shall indemnify and hold harmless each present
and former director and officer of the Company and its subsidiaries, determined
on the Closing Date (the "Indemnified Parties"), against any claims, losses,
liabilities, damages, judgments, fines, fees, costs or expenses, including
without limitation attorneys' fees and disbursements (collectively, "Costs"),
incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, arising
out of or pertaining to matters existing or occurring on or prior to the Closing
Date, whether asserted or claimed prior to, on or after the Closing Date, to the
fullest extent that the Company or such subsidiary would have



                                      -26-
 

<PAGE>   31




been permitted, under applicable law, indemnification agreements existing on the
date hereof, the Articles of Association or Memorandum of Association of the
Company or such subsidiary in effect on the date hereof, to indemnify such
Person (and the Company shall also advance expenses as incurred to the fullest
extent permitted under applicable law provided the person to whom expenses are
advanced provides an undertaking to repay such advances if it is ultimately
determined that such person is not entitled to indemnification).

         (b) Any Indemnified Party wishing to claim indemnification under this
Section 5.9, upon learning of any such claim, action, suit, proceeding or
investigation, shall promptly notify the Company thereof, but the failure to so
notify shall not relieve the Company of any liability or obligation it may have
to such Indemnified Party except, and only to the extent, that such failure
materially prejudices the Company. In the event of any such claim, action, suit,
proceeding or investigation (whether arising before, on or after the Closing
Date), the Company shall have the right to assume the defense thereof and the
Company shall not be liable to such Indemnified Parties for any legal expenses
of other counsel or any other expenses subsequently incurred by such Indemnified
Parties in connection with the defense thereof, except that if the Company
elects not to assume such defense or counsel for the Indemnified Parties advises
that there are issues that raise conflicts of interest between the Company and
the Indemnified Parties, the Indemnified Parties may retain counsel satisfactory
to them, and the Company shall pay all reasonable fees and expenses of such
counsel for the Indemnified Parties promptly as statements therefor are
received. If such indemnity is not available with respect to any Indemnified
Party, then the Company and the Indemnified Party shall contribute to the amount
payable in such proportion as is appropriate to reflect relative faults and
benefits. In the event that any claim or claims are asserted or made within the
aforesaid six-year period, all rights to indemnification in respect of any such
claim or claims shall continue until the final disposition of any and all such
claims.

         (c) Notwithstanding anything herein to the contrary, if any claim,
action, suit, proceeding or investigation (whether arising before, on or after
the Closing Date) is made against any present or former director or officer of
the Company, on or prior to the sixth anniversary of the Closing Date, the
provisions of this Section 5.9 shall continue in effect until the final
disposition of such claim, action, suit, proceeding or investigation.

         (d) This covenant is intended to be for the benefit of, and shall be
enforceable by, each of the Indemnified Parties and their respective heirs and
legal representatives. The indemnification provided for herein shall not be
deemed exclusive of any other rights to which an Indemnified Party is entitled,
whether pursuant to law, contract or otherwise.

         (e) To the extent that the Company fails to perform any of its
obligations pursuant to this Section 5.9, Purchaser shall assume the obligations
and rights of the Company under this Section 5.9.

         5.10. Purchaser Plans.

         (a) Following the Closing Date, Purchaser shall cause the Company to
provide to persons who were employees of the Company or any of its subsidiaries
prior to the Closing Date (the "Company Personnel") employee benefit plans,
programs and arrangements (the "Purchaser Plans")


                                      -27-
 

<PAGE>   32




which in the aggregate are substantially comparable to those employee benefit
plans, programs and arrangements generally provided to similarly situated
employees of Purchaser from time to time.

         (b) Following the Closing Date, Purchaser shall cause the Purchaser
Plans to recognize any prior accrued service, compensation credit, credit toward
satisfying deductible expense requirements, out-of-pocket expense limits and
maximum lifetime benefit limits of such Company Personnel and/or such Company
Personnel's eligible dependents, to the extent such prior service, credits and
limits were recognized under the comparable employee benefit plans, programs or
arrangements of the Company on the Closing Date, for all purposes under the
Purchaser Plans (including, but not limited to, participation, eligibility,
vesting and the calculation of benefits), and Purchaser shall cause the
Purchaser Plans to waive any preexisting condition, exclusion or limitation
under any such Plan to the extent such condition, exclusion or limitation would
be covered by the comparable plan, program or arrangement of the Company on the
Closing Date.

         (c) Each of the employment agreements, the employment security
agreements and severance agreements for the benefit of Company Personnel
identified in Section 5.10 of the Company Disclosure Schedule shall be continued
by the Company on the Closing Date on the same terms and subject to the same
conditions as in effect under such agreements immediately prior to the Closing
Date.

         5.11. Purchaser Stock Options. Immediately after the Closing Date,
Purchaser will issue, to senior management and key employees of the Company, as
shall be mutually agreed between the senior officers of the Company and
Purchaser, stock options to purchase an aggregate of 500,000 shares of Purchaser
common stock under its stock option plan, vesting ratably over five years, under
agreements in customary form utilized for Purchaser's employees.

         5.12. Israeli Operations. Following the Closing Date, Purchaser intends
that the Company will continue as a legal entity, with the same name, engaged in
the development, production, marketing and distribution of the software products
of the Company and that the business operations and facilities of the Company
(including its research and development activities) remain in Israel.

         5.13. Boole & Babbage Shares. Purchaser shall use its reasonable
efforts to cause Boole & Babbage, Inc. to tender any shares held by it into the
Offer.

                                   ARTICLE VI
                                   TERMINATION

         6.1. Termination. This Agreement may be terminated and the Offer may be
abandoned at any time, prior to the Closing Date:

         (a) by mutual written consent of the Company and Purchaser;

         (b) by either the Company or Purchaser, if the Closing Date shall not
have occurred on or before September 12, 1999; provided, that either the Company
or the Purchaser may terminate this Agreement if (i) the Closing Date shall not
have occurred on or before July 12, 1999, and (ii) within 10 days of expiration
of the initial Offer hereunder, Purchaser has not elected to commence


                                      -28-
 

<PAGE>   33




a new Offer pursuant to Section 7.12 hereof; and provided, further that the
right to terminate this Agreement under this clause (b) shall not be available
to any party whose misrepresentation in this Agreement or whose failure to
perform any of its covenants and agreements or to satisfy any obligation under
this Agreement has been the cause of or resulted in the failure of the Closing
Date to occur on or before the applicable dates specified herein;

         (c) by either the Company or Purchaser, if any federal or state court
of competent jurisdiction or other federal or state governmental or regulatory
body shall have issued any judgment, injunction, order or decree prohibiting,
enjoining or otherwise restraining the transactions contemplated by this
Agreement and such judgment, injunction, order or decree shall have become final
and nonappealable (provided, however, that the party seeking to terminate this
Agreement pursuant to this clause (c) shall have used commercially reasonable
efforts to remove such judgment, injunction, order or decree) or if any statute,
rule, regulation or executive order promulgated or enacted by any federal or
state governmental authority after the date of this Agreement which prohibits
the consummation of the Offer shall be in effect;

         (d) by the Company, if (i) Purchaser fails to commence the Offer as
provided in Section 1.1 other than as a result of any action by the Company in
violation of this Agreement, (ii) the Offer expires or is terminated without any
Shares being purchased thereunder and Purchaser does not commence a new Offer
pursuant to Section 7.12 or (iii) Purchaser fails to purchase validly tendered
Shares in violation of the terms and conditions of the Offer or this Agreement;

         (e) by Purchaser, if (i) the Offer is not commenced as provided in
Section 1.1 directly as a result of actions or inaction by the Company in
violation of this Agreement, (ii) the Company's Board of Directors shall have
withdrawn, withheld or modified in a manner adverse to Purchaser its approval of
this Agreement or the Offer pursuant to Section 5.8 or (iii) the Offer is
terminated or expires as a result of the failure of a condition specified in
Exhibit A hereto without the purchase of any Shares thereunder, unless such
termination or expiration has been caused by or resulted from the failure of
Purchaser to perform any covenants and agreements of Purchaser contained in this
Agreement;

         (f) by the Company, if its Board of Directors shall have withdrawn,
withheld or modified in a manner adverse to Purchaser its approval of this
Agreement or the Offer in accordance with Section 5.8 and paid to Purchaser the
Break-Up Fee;

         (g) by Purchaser, if there shall have been a material breach of any
representation, warranty or material covenant or agreement on the part of the
Company, which is incurable or which is not cured after thirty days' written
notice by Purchaser to the Company; or

         (h) by the Company, if there shall have been a material breach of any
representation, warranty or material covenant or agreement on the part of
Purchaser, which is incurable or which is not cured after thirty days' written
notice by the Company to Purchaser.

         6.2 Effect of Termination. In the event of any termination of this
Agreement pursuant to Section 6.1, this Agreement forthwith shall become void
and of no further force or effect, and no party hereto (or any of its
affiliates, directors, officers, agents or representatives) shall have any


                                      -29-

liability or obligation hereunder, except in any such case (a) as provided in
Sections 5.2(b) (Confidentiality), 5.4 (Non-Solicitation), 5.7 (Public
Announcements), and 6.3 (Fees and Expenses), which shall survive any such
termination and (b) to the extent such termination results from the breach by
such party of any of its representations, warranties, covenants or agreements
contained in this Agreement.

         6.3. Fees and Expenses. Whether or not the Offer or is consummated, all
costs and expenses incurred in connection with this Agreement and the
transactions contemplated hereby (including, without limitation, fees and
disbursements of counsel, financial advisors and accountants) shall be borne by
the party which incurs such cost or expense.

         any legislative body, court, government or governmental, administrative
         or regulatory authority or agency located or having jurisdiction within
         the United States or the State of Israel, which could reasonably be
         expected to have the effect of: (i) making illegal, materially delaying

         Purchaser of any Shares or the Compulsory Acquisition; (ii) prohibiting
         or materially limiting the ownership or operation by Purchaser or its

         hostilities or any other material international or national calamity
         involving the United States or the State of Israel and, in the case of

         to its terms or amended pursuant to its terms to provide for such
         termination of the Offer;

which, in the good faith judgment of Purchaser makes it inadvisable to proceed
with the Offer or with acceptance for payment or payment for Shares.

         The foregoing conditions are for the sole benefit of Purchaser and may
be asserted or waived by Purchaser in whole or in part at any time or from time
to time in its discretion subject to the terms and conditions of the Tender
Agreement. The failure of Purchaser at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right and each such right shall
be deemed an ongoing right which may be asserted at any time and from time to
time. The Company will deliver to the Purchaser such evidence as Purchaser shall
reasonably request to evidence satisfaction of any of the conditions set forth
above, including certificates executed by officers of the Company.

                 BMC Software to Acquire New Dimension Software

HOUSTON, TX - (March 8, 1999) - BMC Software (Nasdaq: BMCS), the leader in 
providing Application Service Assurance (ASA(TM)) solutions that improve the 
availability, performance and recovery of business-critical applications, 
announced today that it has signed a Share Purchase and Tender Agreement to 
acquire New Dimension Software, Inc. (Nasdaq:DDDDF) for $52.50 per share. New 
Dimension Software is an industry leader in enterprise management, specializing 
in job scheduling, managing computer generated output and documents, and 
security and user administration. The acquisition complements BMC Software's 
pending merger with Boole & Babbage, Inc., which is expected to be completed on 
March 30. Boole & Babbage is currently the exclusive European distributor of 
New Dimension Software's products.

As a result of these strategic acquisitions, BMC Software accelerates the
delivery of solutions that significantly reduce the complexity of managing large
enterprises through innovative products, an extensive worldwide distribution
network and superior technical expertise. BMC Software will gain a significant
presence in Israel, home of New Dimension Software's worldwide headquarters and
a major center for software development and technical expertise. BMC Software
intends to maintain and expand New Dimension Software's operations in Israel.

"The acquisition of New Dimension Software is a perfect fit for BMC Software's 
global strategy of providing Application Service Solutions from the back office 
to the front office and beyond. This acquisition, along with our merger with 
Boole & Babbage, positions BMC Software as a top-tier player in the enterprise 
management industry focused on rapidly delivering value to a business, said Max 
Watson, chairman, president and CEO of BMC Software. "Today, there is already a 
significant degree of product integration between the companies which is good 
for our customers who gain focused, best-of-breed solutions that address their 
critical issues. This combination establishes a new center for technology 
building on strong skills and resources in Israel, which is renowned for its 
high degree of technical skills and superior technology workforce. We will be 
joining IBM, Intel, Microsoft and other leading high technology firms who have 
established significant operations in Israel."

"This transaction is a win-win for all parties: New Dimension Software, BMC
Software, our customers and the industry as a whole. The unique combination of
our companies' product sets, coupled with our existing distribution arrangement
with Boole & Babbage, will enable the new BMC Software to provide
state-of-the-art solutions to manage the entire enterprise," said Dan Barnea,
CEO of New Dimension Software. "Our employees are looking forward to becoming
part of the BMC Software family, one that has a global reputation for excellence
and investment in the companies it acquires."

The transaction is a cash purchase valued at more than $650 million. BMC
Software anticipates an in-process research and development charge of up to 30
percent of the purchase price, with amortization of identifiable intangible
assets over four to five years. Because New Dimension Software is a non-U.S.
corporation, BMC Software expects to treat the acquisition as an asset purchase
for federal income tax purposes, which significantly improves anticipated
earnings and cash flow. BMC Software will effect the acquisition through a cash
tender offer for all outstanding New Dimension Software shares. BMC Software has
entered into option agreements with two holders of more than 60 percent of the
outstanding shares. The agreements give BMC Software the right to purchase these
shares at the tender offer price for a stipulated period of time and require the
shareholders to tender their shares to BMC Software.

"We are paying cash because we believe our stock is greatly undervalued and
prefer to use cash as our acquisition currency," said Bill Austin, senior vice
president and chief financial officer of BMC Software. "We will also avoid the
significant delays associated with stock-based pooling transactions. We hope to
close this transaction within the next 45 days, so that we begin our fiscal 2000
with both Boole & Babbage and New Dimension Software as part of BMC Software's
operations."

When the New Dimension Software and Boole & Babbage transactions are completed,
BMC Software will employ approximately 5,000 people in 26 countries. Trailing
annual revenues of the combined companies will be approximately $1.4 billion.

BMC Software's ASA product lines ensure that key business applications are
available, perform optimally and can be rapidly recovered in the event of an
outage. This enhances the service delivered to the business by the information
technology (IT) organization and significantly improves business productivity
and return on investment in IT assets.

The company's combined product line will provide customers the ability to manage
all components of the enterprise which affect application availability and the
ability to solve unique application availability problems. Customers will
realize these benefits:

        o Across all major platforms (OS/390, UNIX, NT, Internet)

        o Across database, middleware, mail and messaging, custom and 
          packaged applications, Internet and Web servers
 
        o Across all major functional areas: event management, 
          performance analysis, capacity planning, backup and recovery, 
          job scheduling, output management and security administration

This news release contains both historical information and forward-looking
information. For example, statements in this discussion regarding BMC Software's
future financial and operating results, the development of and anticipated
markets for BMC Software's products, BMC Software's operating strategies,
anticipated acquisition benefits and other statements that are not statements of
historical fact are forward looking statements. Actual results could differ
materially from any expectation, estimate or projection conveyed by these
statements and there can be no assurance that any such expectation, estimate or
projection will be met. Numerous important factors, risks and uncertainties
affect BMC Software's operating results and could cause actual results to differ
from the results implied by these or any other forward looking statements. These
factors include, but are not limited to, the following: 1) BMC Software's
revenues and earnings are subject to a number of factors, including the
significant percentage of quarterly sales typically closed at the end of each
quarter, that make estimation of operating results prior to the end of a quarter
extremely uncertain; 2) competition for BMC Software's products is increasing
for both the open systems and the mainframe database utility products; 3)
international results have been volatile over the last two years; 4) BMC
Software continues to increasingly depend on large enterprise license
transactions as an integral part of its core mainframe and distributed systems
businesses; 5) the uncertainties of whether new software products and product
strategies will be successful; 6) the high degree of difficulty of integrating
different software products and technologies and the general risks associated
with mergers of high technology companies, including the potential loss of key
personnel and cultural conflicts; and 7) the additional risks and important
factors described in BMC Software's, New Dimension Software's and Boole &
Babbage's Annual Report to Stockholders on Forms 10-K and 10-Q and other filings
with the SEC.

Attention: Michael Shryock

     You (the "Borrower") have requested that Chase Securities Inc. ("CSI") 
agree to structure, arrange and syndicate a senior revolving credit facility in 
an aggregate amount of up to $500,000,000 (the "Facility"), and that Chase Bank 
of Texas, National Association ("Chase"), commit to provide the entire 
principal amount of the Facility and to serve as administrative agent for the 
Facility.

     CSI is pleased to advise you that it is willing to act as exclusive 
advisor, lead arranger, and book manager for the Facility.

     Furthermore, Chase is pleased to advise you of (a) its commitment to 
provide the entire amount of the Facility upon the terms and subject to the 
conditions set forth or referred to in this commitment letter (the "Commitment 
Letter") and in the Summary of Terms and Conditions attached hereto as Exhibit 
A (the "Term Sheet").

     It is agreed that Chase will act as the sole and exclusive Administrative 
Agent, and that CSI will act as the sole and exclusive advisor, lead arranger, 
and book manager (in such capacity, the "Arranger"), for the Facility, and each 
will, in such capacities, perform the duties and exercise the authority 
customarily performed and exercised by it in such roles. You agree that no
other agents, co-agents or arrangers will be appointed, no other titles will be 
awarded and no compensation (other than that expressly contemplated by the Term 
Sheet and the Fee Letter referred to below) will be paid in connection with the 
Facility unless you and we shall so agree.

     We intend to syndicate the Facility to a group of financial institutions 
(together with Chase, the "Lenders") identified by us in consultation with you. 
CSI intends to commence syndication efforts promptly upon the execution of this 
Commitment Letter, and you agree actively to assist CSI in completing a 
syndication satisfactory to it. Such assistance shall include (a) your using 
commercially reasonable efforts to ensure that the syndication efforts benefit 
materially from your existing lending relationships, (b) direct contact between 
senior management and advisors of the Borrower and the proposed Lenders, (c) 
assistance in the preparation of a Confidential Information Memorandum and 
other marketing materials to be used in connection with the syndication and (d) 
the hosting, with CSI, of one or more meetings of prospective Lenders.

     As the Arranger, CSI will manage all aspects of the syndication, including 
decisions as to the selection of institutions to be approached and when they 
will be approached, when their commitments will be accepted, which institutions 
will participate, the allocations of the commitments among the Lenders and the 
amount and distribution of fees among the Lenders. In acting as the Arranger, 
CSI will have no responsibility other than to arrange the syndication. To 
assist CSI in its syndication efforts, you agree

promptly to prepare and provide to CSI and Chase all information with respect 
to the Borrower and the transactions contemplated hereby, including all 
financial information and projections (the "Projections"), as we may reasonably 
request in connection with the arrangement and syndication of the Facility. You 
hereby represent and covenant that (a) all information other than the 
Projections (the "Information") that has been or will be made available to 
Chase or CSI by you or any of your representatives is or will be, when 
furnished, complete and correct in all material respects and does not or will 
not, when furnished, contain any untrue statement of a material fact or omit to 
state a material fact necessary in order to make the statements contained 
therein not materially misleading in light of the circumstances under which 
such statements are made and (b) the Projections that have been or will be made 
available to Chase or CSI by you or any of your representatives have been or 
will be prepared in good faith based upon reasonable assumptions. You 
understand that in arranging and syndicating the Facility we may use and rely 
on the Information and Projections without independent verification thereof.

     As consideration for Chase's commitment hereunder and CSI's agreement to
perform the services described herein, you agree to pay to Chase the
nonrefundable fees in the Fee Letter dated the date hereof and delivered
herewith (the "Fee Letter").

     Chase and CSI shall be entitled, after consultation with you and with your
consent, such consent not to be unreasonably withheld, to change the structure,
terms, amount or pricing of the Facility if the syndication has not been
completed and if Chase and CSI determine that such changes are advisable in
order to ensure a successful syndication of the Facility. Chase's commitment
hereunder is subject to the agreements in this paragraph.

     Chase's commitment hereunder and CSI's agreement to perform the services

Borrower and the acquisition candidate contemplated with this Facility, (c) our

matter disclosed to us prior to the date hereof, (d) there not having occurred a
material disruption of or material adverse change in financial, banking or
capital market conditions that, in our judgment, could materially impair the
syndication of the Facility, (e) our satisfaction that prior to and during the
syndication of the Facility there shall be no competing offering, placement or
arrangement of any debt securities or bank financing by or on behalf of the
Borrower or any affiliate thereof, (f) the negotiation, execution and delivery
on or before May 7, 1999 of definitive documentation with respect to the
Facility satisfactory to Chase and its counsel and (h) the other conditions set
forth or referred to in the Term Sheet. The terms and conditions of Chase's
commitment hereunder and of the Facility are not limited to those set forth
herein and in the Term Sheet. Those matters that are not covered by the
provisions hereof and of the Term Sheet are subject to the approval and
agreement of Chase, CSI and the Borrower.

     You agree to indemnify and hold harmless Chase, CSI, the other Lenders,
their respective affiliates and their respective officers, directors, employees,
advisors, and agents (each, an "indemnified person") from and against any and
all losses, claims, damages and liabilities to which any such indemnified person
may become subject arising out of or in connection with this Commitment Letter,
the Facility, the use of the proceeds thereof or any related transaction or any
claim, litigation, investigation or proceeding relating to any of the foregoing,
regardless of whether any indemnified person is a party thereto, and to

incurred in connection with investigating or defending any of the foregoing,
provided that the foregoing indemnity will not, as to any indemnified person,

with respect thereto. This Commitment Letter shall be governed by, and construed
in accordance with, the laws of the State of Texas.

neither this Commitment Letter, the Term Sheet or the Fee Letter nor any of
their terms or substance shall be disclosed, directly or indirectly, to any
other person except (a) to your officers, agents and advisors who are directly

judicial or administrative proceeding or as otherwise required by law (in which
case you agree to inform us promptly thereof), provided, that the foregoing
restrictions shall cease to apply (except in respect of the Fee Letter and its
terms and substance) after this Commitment Letter has been accepted by you.

         You acknowledge that CSI and Chase may be providing debt financing,
equity capital or other services (including financial advisory services) to

                        indemnified party).

BMC Software, Inc.
2101 City West Blvd.
Houston, Texas 77042

Attn: Stephen Solcher, Vice President and Treasurer
      Mike Shryock, Finance Manager

Re:   Proposed $500,000,000 Revolving Credit Facility (the "Facility")

Dear Stephen and Mike:

We, ABN AMRO Bank N.V. ("ABN AMRO"), hereby issue our commitment to the 
Facility in a principal amount of $125,000,000 based on the terms and 
conditions outlined in the revised Summary of Terms and Conditions dated March 
8, 1999 (the "Term Sheet") sent to us by BMC Software, Inc. as amended by Mike 
Shryock's letter to ABN AMRO dated March 9, 1999. Our commitment to this 
financing is subject to the negotiation and execution of documentation 
satisfactory to ABN AMRO.

The commitment offered by ABN AMRO herein is to underwrite the aggregate amount 
of $125,000,000. If BMC accepts this commitment offer, ABN AMRO undertakes to 
syndicate the Facility; provided, however, that the inability of ABN AMRO to 
complete such syndication shall not affect the commitment of ABN AMRO or the 
obligations of BMC hereunder.

BMC agrees to provide ABN AMRO with all information and take such other actions 
as ABN AMRO may reasonably request to facilitate the syndication of the 
Facility by ABN AMRO. ABN AMRO agrees to treat all confidential information 
provided to it by BMC on a confidential basis in accordance with customary 
banking practices subject to customary exceptions. ABN AMRO may provide such 
information to potential syndicate banks and financial institutions provided 
such banks and financial institutions similarly agree to maintain such 
confidentiality.

This letter is not meant to encompass, nor shall it be construed as 
encompassing, all of the terms and conditions of the Facility. It is intended 
to outline the principal points of business understandings concerning the 
Facility. The commitment of ABN AMRO hereunder is subject to completion by ABN 
AMRO of satisfactory due diligence and the execution of a definitive lease 
agreement and other lease documentation in form and substance satisfactory to 
ABN AMRO. If ABN AMRO and BMC are unable to agree upon such documentation, they 
shall have no further obligations to each other hereunder
<PAGE>   14
[ABN-AMRO BANK LOGO]

except that BMC shall be obligated to reimburse ABN AMRO for its out-of-pocket 
fees, costs and expenses as provided herein.

In consideration of the commitments provided by ABN AMRO hereunder, BMC agrees
to indemnify and hold harmless each of ABN AMRO and its officers, directors,
employees, agents, advisors and affiliates for all claims, damages, losses,
liabilities and expenses (including, without limitation, reasonable fees and
disbursements of counsel) incurred by any of them in connection with this
commitment letter, the Facility, the use by BMC of the Facility or the proceeds
thereof, the collateral for the Facility, the lease documents, any related
document, instrument or agreement or any transaction contemplated hereby or
thereby whether or not such transactions are consummated, except for the portion
of such claims, damages, losses, liabilities and expenses caused by such party's
gross negligence or willful misconduct.

The commitment set forth in this letter is personal to BMC and may not be 
transferred or assigned to any other party without the prior written consent of 
ABN AMRO. Except as otherwise required by law, neither this letter nor any part 
hereof may, without the prior written consent of ABN AMRO, be disclosed or 
exhibited to any other party except BMC's accountants, attorneys and other 
advisors, and then, in each case, only in connection with the transactions 
contemplated hereby and on a confidential basis.

If the commitment offered herein is satisfactory, please indicate BMC's 
acceptance by having an authorized officer of BMC sign and date each of the 
enclosed copies of this letter and the attached fee agreement letter and 
delivering the executed copies of each, to ABN AMRO. ABN AMRO reserves the 
right to terminate the commitment offer set forth herein at any time prior to 
receipt by ABN AMRO of such executed copies. Unless so accepted or otherwise 
terminated by ABN AMRO on or prior to March 15, 1999, the offer set forth 
herein will expire on that date.

Upon the acceptance by BMC of the commitment offer set forth in this letter, ABN
AMRO will commence its due diligence and instruct its counsel to commence
documentation. By accepting this offer, BMC agrees to reimburse ABN AMRO for all
reasonable fees, costs and expenses (whether incurred before or after the date
hereof), including, without limitation, audit fees, out-of-pocket syndication
expenses, and fees and disbursements of counsel for ABN AMRO, incurred by ABN
AMRO in connection with its due diligence, the syndication of the Facility and
the negotiation, preparation, execution, delivery and enforcement of the lease
documents, whether or not any money is advanced by ABN AMRO under the Facility,
any of the transactions contemplated hereby are consummated or any documents are
agreed to and executed. If BMC accepts this offer, ABN AMRO's commitment
hereunder shall continue until September 30, 1999, on which date such commitment
shall expire unless final documents have been executed by ABN AMRO, BMC and the
other parties thereto on or prior to such date.

This letter shall be governed by and construed in accordance with the laws of
the State of California without regard to conflicts of law principles.

Closing and funding by ABN-AMRO to occur on or before April 7th, 1999.

<PAGE>   4




                                    (B) to the extent that such (1) are intended
to, or could reasonably be expected to, impede, interfere with, delay, postpone,

transactions contemplated thereby,

                                    (B) approve an amendment to the Company's

issued and outstanding Shares of the Company shall be entitled to appoint and
remove any and all members of the Board of Directors of the Company, by means of
a written notice signed by such holders of the Company, and

                                    (C) approve any and all other matters

                  (b) In the event that (i) the 90% Condition is not satisfied,
(ii) Purchaser notifies Shareholder Group that Purchaser is prepared to close
the Offer but for the fact that the 90% Condition is not satisfied, and (iii)
the tender by Shareholder Group of the Underlying Shares, either alone or when
aggregated with other Company Options, would cause the 90% Condition to be
satisfied, then Shareholder Group hereby agrees that, at any time prior to the
Termination Date, immediately upon the request of Purchaser, it shall exercise
all Company Options Beneficially Owned by it and immediately tender the
Underlying Shares received upon such exercise into the Offer (and not withdraw
such Underlying Shares so tendered). Purchaser shall advance to Shareholder
Group the funds necessary to pay the exercise price of such Options, and

         3.2 Exercise of the Purchase Option.

                  (a) Subject to the conditions set forth in Section 3.3, the
Purchase Option may be exercised in whole at any time, and in part from time to
time, from and after the Offer Termination Date and ending as of the Termination
Date; provided, however, that in the event Purchaser exercises its Purchase
Option hereunder it shall exercise its Purchase Option in a proportionate amount
under that certain Shareholder Agreement with Yossie Hollander of even date
herewith entered into in connection with the Tender Agreement.

                  (b) In the event Purchaser wishes to exercise the Purchase
Option, Purchaser will send a written notice to Shareholder Group specifying a
place, date (not less than two business days nor more than 10 calendar days
after the date such notice is given) and time for the closing of the purchase of
such Shares (the "Closing").

                  (c) The purchase price payable to Shareholder Group with

Per Share Amount and (ii) the number of Applicable Shares to be purchased upon
such exercise.

                  (a) At the Closing, Shareholder Group will deliver to
Purchaser a certificate or certificates representing the Shares being purchased,
duly endorsed for transfer or accompanied by appropriate stock powers duly
executed in blank, and Purchaser will pay the purchase price in immediately
available funds by wire transfer to an account designated by Shareholder Group.
Transfer taxes, if any, imposed as a result of the exercise of the Purchase
Option and the transfer of any Applicable Shares will be paid by Shareholder
Group.

                  (b) The obligation of Purchaser and Shareholder Group to
consummate the purchase and sale of the Applicable Shares pursuant to this
Article III will be subject to the fulfillment of the following conditions:

                           (i) the expiration or termination of the waiting
period applicable to the consummation of such transactions under the HSR Act and
any other applicable antitrust laws; and

                           (ii) none of the parties hereto shall be subject to
any order or injunction of a court of competent jurisdiction which prohibits the
consummation of such transactions.

                  (c) The obligations of Shareholder Group pursuant to this
Article III shall also be subject to Purchaser not violating any of its material
obligations under the Tender Agreement.

Each of the parties hereto will promptly make and will use all reasonable
efforts to cause each of their respective affiliates to make, all such filings
and take all such actions as may be reasonably required in order to permit the
lawful exercise of the Purchase Option, as promptly as possible. The date of any
Closing may be extended, if required, to the next business day following (1) the
date that any applicable waiting period(s) under the HSR Act and any other
applicable antitrust laws shall have expired or been earlier terminated, (2) the
date that all other necessary governmental approvals for the sale of the Shares
for which the Purchase Option shall have been exercised shall have been
obtained, and (3) the satisfaction of any other condition to the Closing under
the Tender Agreement.

                                   ARTICLE IV
                                     CAPTURE

                  4.1 Capture. In the event that the Applicable Shares of
Shareholder Group are sold, transferred, exchanged, canceled or disposed of in
connection with or as a result of any Company Transaction Proposal that is in
existence on, or that has been otherwise made prior to the Termination Date (an
"Alternative Disposition") then, within five business days after the closing of
such Alternative Disposition, Shareholder Group shall tender and pay to, or
shall cause to be tendered and paid to, Purchaser (or its designee), in
immediately available funds, the Profit realized from such Alternative
Disposition, less any withholdings.

                  4.2 Profit. As used in this Article IV, "Profit" shall mean an
amount equal to the excess, if any, of (a) the Alternative Transaction
Consideration over (b) the Per Share Amount multiplied by Shareholder Group's
Applicable Shares sold, transferred, exchanged, canceled or

 
                                        6

disposed of in such Alternative Disposition. For purposes of determining Profit,
(i) all non-cash items shall be valued based upon the fair market value thereof
as determined by an independent expert selected by Purchaser and who is
reasonably acceptable to Shareholder Group, (ii) all deferred payments or
consideration shall be discounted to reflect a market rate of net present value
thereof as determined by the above-referenced independent expert, and (iii) all
contingent payments will be assumed to have been paid. In the event any
contingent payments included in the determination of Profit ultimately are not
paid pursuant to an Alternative Disposition, then Purchaser shall promptly
reimburse Shareholder Group for any amounts paid to Purchaser hereunder in
respect of such uncollected contingent payments promptly after receipt of
written notice of such non-payment.

Agreement or the Offer and (ii) unless otherwise distributed to Purchaser, to
Shareholder Group on the Termination Date. All Applicable Shares tendered in the
Offer and withdrawn or not purchased in the Offer prior to the Termination Date
shall be returned to the Escrow Agent.

whose consent is required for the execution and delivery of this Agreement or
the consummation by Shareholder Group of the transactions contemplated hereby.

Shares constitute community property, this Agreement has been duly authorized,
executed and delivered by, and constitutes a valid and binding agreement of,
Owner's spouse, enforceable against such person in accordance with its terms.

hereby, except where the failure to obtain such consent, permit, authorization,
approval or filing would not interfere with Shareholder Group's ability to
perform its obligations hereunder, and none of the execution and delivery of
this Agreement by Shareholder Group, the consummation by Shareholder Group of
the transactions contemplated hereby or compliance by Shareholder Group with any
of the provisions hereof shall (i) result in a violation or breach of, or

rise to any third party right of termination, cancellation, material
modification or acceleration) under any of the terms, conditions or provisions
of any note, bond, mortgage, indenture, license, contract, commitment,
arrangement, understanding, agreement or other instrument or obligation of any
kind to which Shareholder Group is a party or by which Shareholder Group or any
of its properties or assets may be bound, or (ii) violate any order, writ,
injunction, decree, judgment, order, statute, rule or regulation applicable to
Shareholder Group or any of its properties or assets, in each such case except
to the extent that any conflict, breach, default or violation would not
interfere with the ability of Shareholder Group to perform its obligations
hereunder. All arrangements, understandings, agreements and other instruments
relating to Shareholder Group's ability to dispose of, tender, vote or grant a
proxy with respect to its Applicable Shares or enter into this Agreement have
been validly terminated.

                  (a) Organization, Standing and Corporate Power. Purchaser is a

                  (b) No Conflicts. No filing with, and no permit,
authorization, consent or approval of, any state or federal public body or
authority is necessary for the execution of this Agreement by Purchaser and the
consummation by Purchaser of the transactions contemplated hereby, except where
the failure to obtain such consent, permit, authorization, approval or filing
would not interfere with its ability to perform its obligations hereunder, and
none of the execution and delivery of this Agreement by Purchaser, the
consummation by Purchaser of the transactions contemplated hereby or compliance
by Purchaser with any of the provisions hereof shall (i) conflict with or result
in any breach of any applicable organizational documents applicable to

(ii) result in a violation or breach of, or constitute (with or without notice
or lapse of time or both) a default (or give rise to any third party right of
termination, cancellation, material modification or acceleration) under any of
the terms, conditions or provisions of any note, bond, mortgage, indenture,
license, contract, commitment, arrangement, understanding, agreement or other
instrument or obligation of any kind to which Purchaser is a party or by which
Purchaser or any of Purchaser's properties or assets may be bound, or (iii)
violate any order, writ, injunction, decree, judgment, order, statute, rule or
regulation applicable to Purchaser or any of Purchaser's properties or assets,
in each such case except to the extent that any conflict, breach, default or
violation would not interfere with the ability of Purchaser to perform its
obligations hereunder.

                  (c) Execution, Delivery and Performance by Purchaser. The
execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated hereby have been duly authorized by the Board of
Directors of Purchaser, and Purchaser has taken all other actions required by
law, its certificate of incorporation and its by-laws to consummate the
transactions contemplated by this Agreement. This Agreement constitutes the
valid and binding obligations of Purchaser and is enforceable in accordance with
its terms, except as enforceability may be subject to bankruptcy, insolvency,
reorganization, moratorium or other similar laws relating to or affecting
creditors' rights generally.

         7.3 Purchaser will perform its obligations under the Tender Agreement.

as a director or officer of Company and nothing herein shall limit or affect any

obligations as a director and officer of Company. Subject to the foregoing, all

         8.8 Severability. Whenever possible, each provision or portion of any
provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such
invalidity, illegality or unenforceability will not affect any other provision
or portion of any provision in such jurisdiction, and this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision or portion of any provision had never been
contained herein.

         8.9 Specific Performance. Each of the parties hereto recognizes and
acknowledges that a breach by ECS or either Owner of any covenants or agreements
contained in this Agreement will cause the Purchaser to sustain damages for
which they would not have an adequate remedy at law for money damages, and
therefore each of the parties hereto agrees that in the event of any such breach
the Purchaser shall be entitled to the remedy of specific performance, without
the requirement of posting any bond, of such covenants and agreements and
injunctive and other equitable relief in addition to any other remedy to which
it may be entitled, at law or in equity.

         8.10 Remedies Cumulative. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise of any thereof
by any party shall not preclude the simultaneous or later exercise of any other
such right, power or remedy by such party.

         8.11 No Waiver. The failure of any party hereto to exercise any right,
power or remedy provided under this Agreement or otherwise available in respect
hereof at law or in equity, or to insist upon compliance by any other party
hereto with its obligations hereunder, and any custom or practice of the parties
at variance with the terms hereof, shall not constitute a waiver by such party
of its right to exercise any such or other right, power or remedy or to demand
such compliance.

         8.12 No Third Party Beneficiaries. This Agreement is not intended to be
for the benefit of, and shall not be enforceable by, any person or entity who or
which is not a party hereto; provided that, in the event of either Owner's
death, the benefits and obligations of such Owner hereunder shall inure to his
or her successors and heirs.

         8.13 Governing Law. This Agreement shall be governed and construed in
accordance with the laws of the State of Delaware, without giving effect to the
principles of conflicts of law thereof.

         8.14 Descriptive Headings. The descriptive headings used herein are
inserted for convenience of reference only and are not intended to be part of or
to affect the meaning or interpretation of this Agreement.

         8.15 Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed to be an original, but all of which, taken together,
shall constitute one and the same Agreement. This Agreement shall not be
effective as to any party hereto until such time as this Agreement or a
counterpart thereof has been executed and delivered by each party hereto.

         8.16 Trust Funds. In the event that any party hereto should receive any
funds that are to be paid to another party pursuant to the terms of this
Agreement, then the receiving party shall hold such funds in trust for the
benefit of the party entitled to receive such funds and shall promptly pay such
funds to the party entitled to receive such funds in accordance with this

                              SHAREHOLDER AGREEMENT

         THIS SHAREHOLDER AGREEMENT, dated as of March 7, 1999 (this
"Agreement"), is made and entered into between BMC Software, Inc., a Delaware
corporation ("Purchaser") and Yossie Hollander (the "Shareholder").

                                   WITNESSETH

         WHEREAS, concurrently herewith, Purchaser and New Dimension Software
Ltd., an Israeli corporation (the "Company"), are entering into a Share Purchase
and Tender Agreement (as such agreement may hereafter be amended from time to
time, the "Tender Agreement"); and

         WHEREAS, as an inducement and a condition to entering into the Tender
Agreement, Purchaser has required that Shareholder agree, and Shareholder has
agreed, to enter into this Agreement;

         NOW, THEREFORE, in consideration of the foregoing and the
representations, warranties, covenants and agreements contained herein and the
benefits to be received by the parties under the terms of the Tender Agreement,
the parties hereto, intending to be legally bound, hereby agree as follows:

                                    ARTICLE I
                                   DEFINITIONS

         (a) Capitalized terms used and defined herein shall have the respective
meanings ascribed to them in the Tender Agreement. For purposes of this
Agreement:

                  (i) "Alternative Disposition" shall have the meaning ascribed
to such term in Article IV.

                  (ii) "Alternative Transaction Consideration" shall mean all
cash, securities, settlement or termination amounts, notes or other debt
instruments, and other consideration received or to be received, directly or
indirectly, by Shareholder and his affiliates in connection with or as a result
of an Alternative Disposition or any agreements or arrangements (including,
without limitation, any employment agreement, consulting agreement,
non-competition agreement, confidentiality agreement, settlement agreement or
release agreement) entered into, directly or indirectly, by Shareholder or his
affiliates (excluding officers and directors of Company) as a part of or in
connection with the Alternative Disposition or Company Transaction Proposal.

                  (iii) "Applicable Shares " means all Shares that are

<PAGE>   2

                  (iv) "Beneficially Own" or "Beneficial Ownership" with respect
to any securities shall mean bearing "beneficial ownership" of such securities
(as determined pursuant to Rule 13d-3 under the Exchange Act), including
pursuant to any agreement, arrangement or understanding, whether or not in
writing. Without duplicative counting of the same securities by the same holder,
securities Beneficially Owned by a Person shall include (i) securities
Beneficially Owned by all other Persons (who are affiliates of such Person
excluding officers and directors of Company) who together with such Person would
constitute a "group" within the meaning of Section 13(d)(3) of the Exchange Act

                  (v) "90% Condition" shall be such condition as set forth in
paragraph (1) of Exhibit A to the Tender Agreement.

                  (vi) "Offer Termination Date" shall mean the date the Offer
terminates or expires without the purchase of Shares thereunder; provided,
however, that if Purchaser initiates a new Offer under the terms of the Tender
Agreement on or before midnight, central time in the United States on the 10th
day following such date, the Offer Termination Date shall mean the date such
subsequent Offer terminates or expires without the purchase of Shares
thereunder; provided, however, that the Offer Termination Date will not be later
than the date of termination of the Tender Agreement.

                  (vii) "Per Share Amount" shall mean the price per Share of the
Offer as set forth in Section 1.1 of the Tender Agreement, as such price may be
increased in accordance with the Tender Agreement.

                  (viii) "Purchase Option" shall have the meaning ascribed to
such term in Section 3.1.

                  (ix) "Termination Date" shall mean the date ending on the
first to occur of:

                           (1)  the Closing Date;

                           (2)  the Offer Termination Date; or

                           (3) midnight, central time in the United States, on
the date all of the conditions to the Offer set forth in Exhibit A to the Tender
Agreement have been satisfied, except for the conditions set forth in paragraphs
(6)(d)(ii) or (6)(e), and Purchaser elects to terminate the Tender Agreement
without the purchase of Shares thereunder; provided, however, that,
notwithstanding subparagraphs (2) and (3) above, if after the date of this
Agreement (x) any person, entity or group (within the meaning of Section
13(d)(3) of the Exchange Act) (other than the Purchaser or any affiliate of
Purchaser) acquires more than 5% or more of the outstanding Shares and fails to
tender such Shares in the Offer and continues to hold such Shares and the Offer
is terminated as a result of the failure of the 90%Condition to be satisfied,
the Termination Date shall be the date 150 days after the Offer Termination
Date, or (y) there is a public


                                       2

<PAGE>   3


announcement of, or the disclosure to the management, board of directors,
shareholders or advisors of the Company of, a Company Transaction Proposal, and
the board of directors of the Company rejects such Company Transaction Proposal
and continues to recommend the Offer and the Offer is terminated as a result of
the failure of the 90%Condition to be satisfied, the Termination Date shall be
the date 120 days after the Offer Termination Date, or (z) there is a public

                           (iii) for the proposals to:

                                    (A) approve the right of the directors of
the Company to sell their Shares to the Purchaser pursuant to the Offer and the
transactions contemplated thereby,

                                    (B) approve an amendment to the Company's

                                    (C) approve any and all other matters

substitution), from and after the date of this Agreement and ending as of the
Termination Date, to vote his Applicable Shares, or to grant a consent or
approval in respect of his Applicable Shares on any and all matters relating to

                  (a) Shareholder hereby agrees that he shall (i) tender all of
his Applicable Shares into the Offer promptly, and in any event no later than
the third business day following the commencement of the Offer, and (ii) not
withdraw any Applicable Shares so tendered prior to the Offer Termination Date;
provided, however, that Shareholder may delay the tender of up to 75,000 of his
Shares until notified by Purchaser that such tender is required by Purchaser.

                  (b) In the event that (i) the 90% Condition is not satisfied,
(ii) Purchaser notifies Shareholder that Purchaser is prepared to close the
Offer but for the fact that the 90% Condition is not satisfied, and (iii) the
tender by Shareholder of the Underlying Shares, either alone or when aggregated
with other Company Options, would cause the 90% Condition to be satisfied, then
Shareholder hereby agrees that, at any time prior to the Termination Date,
immediately upon the request of Purchaser, he shall exercise all Company Options
Beneficially Owned by him and immediately tender the Underlying Shares received
upon such exercise into the Offer (and not withdraw such Underlying Shares so
tendered). Purchaser shall advance to Shareholder the funds

Purchaser the amount of such advance, without interest, immediately upon receipt
of the Per Share Amount by him for his Underlying Shares.

                  (c) Except as may be required by Section 2.2(b), Shareholder
hereby agrees that he shall not exercise any Company Options that he
Beneficially Owns.

                                   ARTICLE III
                                 PURCHASE OPTION

         3.1 Grant of the Purchase Option. Shareholder hereby grants to

all his Applicable Shares.

         3.2 Exercise of the Purchase Option.

                  (a) Subject to the conditions set forth in Section 3.3, the
Purchase Option may be exercised in whole at any time, and in part from time to
time, from and after the Offer Termination Date and ending as of the Termination
Date; provided, however, that in the event Purchaser exercises its Purchase
Option hereunder it shall exercise its Purchase Option in a proportionate amount
under that certain Shareholder Agreement with Einav Computer Systems Ltd., Roni
A. Einav and Dalia Prashker-Katzman of even date herewith entered into in
connection with the Tender Agreement.

                  (b) In the event Purchaser wishes to exercise the Purchase
Option, Purchaser will send a written notice to Shareholder specifying a place,
date (not less than two business days nor more than 10 calendar days after the
date such notice is given) and time for the closing of the purchase of such
Shares (the "Closing").

                  (c) The purchase price payable to Shareholder with respect to
any exercise of the Purchase Option will be the product of (i) the Per Share
Amount and (ii) the number of Applicable Shares to be purchased upon such
exercise.

         3.3 Closing.

                  (a) At the Closing, Shareholder will deliver to Purchaser a
certificate or certificates representing the Shares being purchased, duly
endorsed for transfer or accompanied by appropriate stock powers duly executed
in blank, and Purchaser will pay the purchase price in immediately available
funds by wire transfer to an account designated by Shareholder. Transfer taxes,
if any, imposed as a result of the exercise of the Purchase Option and the
transfer of any Applicable Shares will be paid by Shareholder.

                  (b) The obligation of Purchaser and Shareholder to consummate
the purchase and sale of the Applicable Shares pursuant to this Article III will
be subject to the fulfillment of the following conditions:

                           (i) the expiration or termination of the waiting
period applicable to the consummation of such transactions under the HSR Act and
any other applicable antitrust laws; and

                           (ii) none of the parties hereto shall be subject to
any order or injunction of a court of competent jurisdiction which prohibits the
consummation of such transactions.

                  (c) The obligations of Shareholder pursuant to this Article
III shall also be subject to Purchaser not violating any of its material
obligations under the Tender Agreement.

Each of the parties will promptly make and will use all reasonable efforts to
cause each of their respective affiliates to make, all such filings and take all
such actions as may be reasonably required in order to permit the lawful
exercise of the Purchase Option, as promptly as possible. The date of any
Closing may be extended, if required, to the next business day following (1) the
date that any applicable waiting period(s) under the HSR Act and any other
applicable antitrust laws shall have expired or been earlier terminated, (2) the
date that all other necessary governmental approvals for the sale of the Shares
for which the Purchase Option shall have been exercised shall have been
obtained, and (3) the satisfaction of any other condition to the Closing under
the Tender Agreement.

                                   ARTICLE IV
                                     CAPTURE

                  4.1 Capture. In the event that the Applicable Shares of
Shareholder are sold, transferred, exchanged, canceled or disposed of in
connection with or as a result of any Company Transaction Proposal that is in
existence on, or that has been otherwise made prior to the Termination Date (an
"Alternative Disposition") then, within five business days after the closing of
such Alternative Disposition, Shareholder shall tender and pay to, or shall
cause to be tendered and paid to, Purchaser (or its designee), in immediately
available funds, the Profit realized from such Alternative Disposition, less any
withholdings.

                  4.2 Profit. As used in this Article IV, "Profit" shall mean an
amount equal to the excess, if any, of (a) the Alternative Transaction
Consideration over (b) the Per Share Amount multiplied by Shareholder's
Applicable Shares sold, transferred, exchanged, canceled or disposed of in such
Alternative Disposition. For purposes of determining Profit, (i) all non-cash
items shall be valued based upon the fair market value thereof as determined by
an independent expert selected by Purchaser and who is reasonably acceptable to
Shareholder, (ii) all deferred payments or consideration shall be discounted to
reflect a market rate of net present value thereof as determined by the
above-referenced independent expert, and (iii) all contingent payments will be
assumed to have been paid. In the event any contingent payments included in the
determination of Profit ultimately are not paid pursuant to an Alternative
Disposition, then Purchaser shall promptly

 
                                        6

<PAGE>   7




reimburse Shareholder for any amounts paid to Purchaser hereunder in respect of
such uncollected contingent payments promptly after receipt of written notice of
such non-payment.

Agreement or the Offer and (ii) unless otherwise distributed to Purchaser, to
Shareholder on the Termination Date. All Applicable Shares tendered in the Offer
and withdrawn or not purchased in the Offer prior to the Termination Date shall
be returned to the Escrow Agent.

                    COVENANTS, REPRESENTATIONS AND WARRANTIES

         7.1 Shareholder hereby represents, warrants and covenants to Purchaser
as follows:

                  (a) Ownership. Shareholder is either (i) the record and
Beneficial Owner of, or (ii) the Beneficial Owner but not the record holder of,
the number of issued and outstanding Shares set forth on Part I of Schedule A
hereto and the Company Options set forth on Part II of Schedule A hereto. As of
the date of this Agreement, the Shares set forth on Part I of Schedule A hereto
constitute all of the issued and outstanding Shares owned of record or
Beneficially Owned by Shareholder. Except as otherwise set forth in Part I to
Schedule A hereto and with respect to encumbrances on up to 75,000 Shares,
Shareholder has sole power of disposition, sole power of conversion, and sole
power to agree to all of the matters set forth in this Agreement, in each case
with respect to all of the Shares set forth on Part I of Schedule A hereto, with
no material limitations, qualifications or restrictions on such rights, subject
to applicable securities laws and the terms of this Agreement.

                  (b) Power; Binding Agreement. Shareholder has the legal
capacity, power and authority to enter into and perform all of Shareholder's
obligations under this Agreement. This Agreement has been duly and validly
authorized by all necessary action, executed and delivered by Shareholder and
constitutes a valid and binding agreement of Shareholder, enforceable against
Shareholder in accordance with its terms. There is no beneficiary or holder of a
voting trust certificate or other interest of any trust of which Shareholder is
trustee whose consent is required for the execution and delivery of this
Agreement or the consummation by Shareholder of the transactions contemplated
hereby. If Shareholder is married and Shareholder's Shares constitute

 
                                        8

<PAGE>   9




community property, this Agreement has been duly authorized, executed and
delivered by, and constitutes a valid and binding agreement of, Shareholder's
spouse, enforceable against such person in accordance with its terms.

                  (c) No Conflicts. Except for the filing of an amendment to
Shareholder's Schedule 13D or 13G, if any, no filing with, and no permit,
authorization, consent or approval of, any state or federal public body or
authority is necessary for the execution of this Agreement by Shareholder and
the consummation by Shareholder of the transactions contemplated hereby, except
where the failure to obtain such consent, permit, authorization, approval or
filing would not interfere with Shareholder's ability to perform his obligations
hereunder, and none of the execution and delivery of this Agreement by
Shareholder, the consummation by Shareholder of the transactions contemplated
hereby or compliance by Shareholder with any of the provisions hereof shall (i)
result in a violation or breach of, or constitute (with or without notice or
lapse of time or both) a default (or give rise to any third party right of
termination, cancellation, material modification or acceleration) under any of
the terms, conditions or provisions of any note, bond, mortgage, indenture,
license, contract, commitment, arrangement, understanding, agreement or other
instrument or obligation of any kind to which Shareholder is a party or by which
Shareholder or any of his properties or assets may be bound, or (ii) violate any
order, writ, injunction, decree, judgment, order, statute, rule or regulation
applicable to Shareholder or any of his properties or assets, in each such case
except to the extent that any conflict, breach, default or violation would not
interfere with the ability of Shareholder to perform his obligations hereunder.
All arrangements, understandings, agreements and other instruments relating to
the Shareholder's ability to dispose of, tender, vote or grant a proxy with
respect to his Applicable Shares or enter into this Agreement have been validly
terminated, except that the Purchaser acknowledges that Shareholder has
encumbered up to 75,000 Shares, which shall be released from such encumbrance on
demand by Purchaser.

                  (d) No Encumbrances. Except as required herein, at all times
during the term hereof, all of Shareholder's Shares or Company Options as set
forth on Part I and II, respectively, of Schedule A hereto will be held by
Shareholder, an affiliate of Shareholder, or by a nominee or custodian for the
benefit of Shareholder, free and clear of all liens, claims, security interests,
proxies, voting trusts or agreements, understandings or arrangements or any
other encumbrances whatsoever, except for any liens, claims, understandings or
arrangements that do not limit or impair Shareholder's ability to perform his
obligations under this Agreement; provided, however, that Shareholder may
encumber up to 75,000 Shares during the term hereof and Shareholder agrees to
cause such Shares to be released from any such encumbrance on demand by
Purchaser.

                  (e) No Solicitation. Shareholder shall comply, and shall cause
each of his affiliates who Beneficially Own any of Shareholder's Applicable
Shares to comply, with the terms of Section 5.8 of the Tender Agreement.

                  (f) Restriction on Transfer, Proxies and Non-Interference.
Except as expressly contemplated hereby, from and after the date of this
Agreement and ending as of the Termination Date, Shareholder shall not, and
shall cause each of his affiliates who Beneficially Own any of

 
                                        9

Shareholder's Applicable Shares or Company Options not to, directly or
indirectly, without the consent of Purchaser: (i) offer for sale, sell,
transfer, tender, pledge, encumber, assign or otherwise dispose of, or enter

assignment or other disposition of, any or all of his Applicable Shares or
Company Options, or any interest therein, (ii) grant any proxies or powers of
attorney, deposit any or all of his Applicable Shares or Company Options into a
voting trust or enter into a voting agreement with respect to his Applicable
Shares or Company Options, (iii) enter into any agreement or arrangement
providing for any of the actions described in clause (i) or (ii) above, or (iv)
take any action that could reasonably be expected to have the effect of
preventing or disabling Shareholder from performing his obligations under this
Agreement. From and after the date of this Agreement and ending as of the
Termination Date, Shareholder shall not enter into any agreement or
understanding with any Person or entity the effect of which would be
inconsistent with or violate the provisions and agreements contained in this
Section 7.1

                  (g) Further Assurances. From time to time, at Purchaser's
request and without further consideration, Shareholder shall execute and deliver
such additional documents as may be necessary or desirable to consummate and
make effective, in the most expeditious manner practicable, the transactions
contemplated by this Agreement.

         7.2 Purchaser hereby represents, warrants and covenants to Shareholder

corporate power and authority to enter into and perform all of its obligations
under this Agreement and to consummate the transactions contemplated hereby.

                  (b) No Conflicts. No filing with, and no permit,
authorization, consent or approval of, any state or federal public body or
authority is necessary for the execution of this Agreement by Purchaser and the
consummation by Purchaser of the transactions contemplated hereby, except where
the failure to obtain such consent, permit, authorization, approval or filing
would not interfere with its ability to perform its obligations hereunder, and
none of the execution and delivery of this Agreement by Purchaser, the
consummation by Purchaser of the transactions contemplated hereby or compliance
by Purchaser with any of the provisions hereof shall (i) conflict with or result
in any breach of any applicable organizational documents applicable to
Purchaser, (ii) result in a violation or breach of, or constitute (with or
without notice or lapse of time or both) a default (or give rise to any third
party right of termination, cancellation, material modification or acceleration)
under any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, license, contract, commitment, arrangement, understanding, agreement
or other instrument or obligation of any kind to which Purchaser is a party or
by which Purchaser or any of Purchaser's properties or assets may be bound, or
(iii) violate any order, writ, injunction, decree, judgment, order, statute,
rule or regulation applicable to Purchaser or any of Purchaser's properties or
assets, in each

 
                                       10

<PAGE>   11




such case except to the extent that any conflict, breach, default or violation
would not interfere with the ability of Purchaser to perform its obligations
hereunder.

                  (c) Execution, Delivery and Performance by Purchaser. The
execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated hereby have been duly authorized by the Board of
Directors of Purchaser, and Purchaser has taken all other actions required by

its terms, except as enforceability may be subject to bankruptcy, insolvency,
reorganization, moratorium or other similar laws relating to or affecting
creditors' rights generally.

         7.3 Purchaser will perform its obligations under the Tender Agreement.

                                  ARTICLE VIII

provision of this Agreement will be interpreted in such manner as to be

<PAGE>   13




illegality or unenforceability will not affect any other provision or portion of
any provision in such jurisdiction, and this Agreement will be reformed,
construed and enforced in such jurisdiction as if such invalid, illegal or
unenforceable provision or portion of any provision had never been contained
herein.

         8.9 Specific Performance. Each of the parties hereto recognizes and
acknowledges that a breach by a Shareholder of any covenants or agreements
contained in this Agreement will cause the Purchaser to sustain damages for
which they would not have an adequate remedy at law for money damages, and
therefore each of the parties hereto agrees that in the event of any such breach
the Purchaser shall be entitled to the remedy of specific performance, without
the requirement of posting any bond, of such covenants and agreements and
injunctive and other equitable relief in addition to any other remedy to which
it may be entitled, at law or in equity.

         8.10 Remedies Cumulative. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise of any thereof
by any party shall not preclude the simultaneous or later exercise of any other
such right, power or remedy by such party.

         8.11 No Waiver. The failure of any party hereto to exercise any right,
power or remedy provided under this Agreement or otherwise available in respect
hereof at law or in equity, or to insist upon compliance by any other party
hereto with its obligations hereunder, and any custom or practice of the parties
at variance with the terms hereof, shall not constitute a waiver by such party
of its right to exercise any such or other right, power or remedy or to demand
such compliance.

         8.12 No Third Party Beneficiaries. This Agreement is not intended to be
for the benefit of, and shall not be enforceable by, any person or entity who or
which is not a party hereto; provided that, in the event of Shareholder's death,
the benefits and obligations of Shareholder hereunder shall inure to his
successors and heirs.

         8.13 Governing Law. This Agreement shall be governed and construed in
accordance with the laws of the State of Delaware, without giving effect to the
principles of conflicts of law thereof.

         8.14 Descriptive Headings. The descriptive headings used herein are
inserted for convenience of reference only and are not intended to be part of or
to affect the meaning or interpretation of this Agreement.

         8.15 Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed to be an original, but all of which, taken together,
shall constitute one and the same Agreement. This Agreement shall not be
effective as to any party hereto until such time as this Agreement or a
counterpart thereof has been executed and delivered by each party hereto.

         8.16 Trust Funds. In the event that any party hereto should receive any
funds that are to be paid to another party pursuant to the terms of this
Agreement, then the receiving party shall hold such funds in trust for the
benefit of the party entitled to receive such funds and shall promptly pay such
funds to the party entitled to receive such funds in accordance with this
