To the Holders of Ordinary Shares of New Dimension Software Ltd.:
 
                                  INTRODUCTION
 
     BMC Software, Inc., a Delaware corporation ("Purchaser"), hereby offers to
purchase all outstanding ordinary shares, par value NIS 0.01 per share (the
"Shares"), of New Dimension Software Ltd., an Israeli corporation (the
"Company"), at a purchase price of $52.50 per Share (the "Offer Price"), net to
the seller in cash, upon the terms and subject to the conditions set forth in
this Offer to Purchase and in the related Letter of Transmittal (which, together
with any amendments or supplements hereto or thereto, collectively constitute
the "Offer").
 
     THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY DETERMINED THAT, AS
OF THE DATE OF THE TENDER AGREEMENT DESCRIBED HEREIN, THE OFFER IS FAIR TO AND
IN THE BEST INTERESTS OF THE SHAREHOLDERS OF THE COMPANY AND 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 AS DESCRIBED HEREIN, TO RECOMMEND ACCEPTANCE OF THE OFFER BY
THE SHAREHOLDERS OF THE COMPANY.
 
     CIBC Oppenheimer Corp. ("CIBC Oppenheimer"), the Company's financial
advisor, has delivered to the Company's board of directors a written opinion,
dated March 7, 1999 to the effect that, as of such date, the Offer Price to be
received in the Offer by the holders of Shares (other than Purchaser and its
affiliates) was fair, from a financial point of view, to such holders. A copy of
the opinion of CIBC Oppenheimer is contained in the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9")
filed with the Securities and Exchange Commission (the "Commission") in
connection with the Offer. A copy of the Schedule 14D-9 is being furnished to
the shareholders herewith.
 
     The Offer is conditioned upon, among other things, (i) there being validly
tendered and not withdrawn prior to the Expiration Date (as defined in Section 1
below) a number of Shares which constitutes at least ninety percent (90%) of the
Shares then issued and outstanding and not owned by Purchaser or its
subsidiaries determined in accordance with Section 236 of the Companies'
Ordinance (New Version) 5743-1983 of the State of Israel (the "Companies
Ordinance") (such condition being referred to herein as the "90% Condition"),
(ii) satisfaction of certain regulatory conditions, including the expiration or
termination prior to the expiration of the Offer of all waiting periods imposed
by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the
"HSR Act"), (iii) certain approvals related to the Offer by the shareholders of
the Company at a Special Meeting as described herein, and (iv) certain other
conditions. See Section 14.
 
     The Offer is being made pursuant to a Share Purchase and Tender Agreement
(the "Tender Agreement") dated as of March 7, 1999, by and between Purchaser and
the Company, which provides for certain agreements between the Company and
Purchaser relating to the Offer, all as described herein.
 
     Concurrently with the execution of the Tender Agreement, Purchaser entered
into Shareholder Agreements, each dated March 7, 1999 (the "Shareholder
Agreements"), with (i) Yossie Hollander and (ii) with Roni A. Einav, Dalia
Prashker and Einav Computer Systems, an Israeli corporation (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 Shares or 61.0% of the issued and
outstanding Shares (excluding outstanding stock options of the Company), (b) the
Principal Shareholders have granted to Purchaser an irrevocable option to
purchase all of such Shares in certain circumstances, and (c) each Principal
Shareholder has granted to Purchaser 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 Tender Agreement and the Shareholder Agreements are more fully
described in Section 12. Certain U.S. federal and Israeli law tax consequences
of the sale of Shares pursuant to the Offer are described in Section 5.
 
                                        1
<PAGE>   4
 
     If Purchaser is successful in acquiring in the Offer at least ninety
percent (90%) of the Shares not presently owned by it or its subsidiaries within
four months of the date hereof (the "Initial Period"), Purchaser has agreed in
the Tender Agreement, in accordance with Section 236 of the Companies Ordinance,
to 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.
Purchaser has agreed to deliver the Notice of Acquisition at any time during the
two month period following the Initial Period.
 
     Shareholders of the Company who object to the Compulsory Acquisition shall
be entitled to file a notice of objection with the Tel Aviv District Court
within one month of receiving the Notice of Acquisition. In the event that any
such objection is filed, the court may issue such relief as it sees fit,
including delaying the completion of the Compulsory Acquisition. One month after
the giving of the Notice of Acquisition, or, if an objection was filed, upon the
court's resolution of such objection, Purchaser shall deliver to the Company a
copy of the Notice of Acquisition and the consideration for the Shares Purchaser
is entitled to purchase, and the Company shall register Purchaser as the record
owner of such Shares. The Company will receive the consideration as trustee for
the shareholders whose Shares are purchased pursuant to the Compulsory
Acquisition.
 
     This Offer to Purchase also serves as a "Plan" or "Contract" under Section
236 of the Companies' Ordinance.
 
     DISSENTERS' RIGHTS ARE NOT AVAILABLE IN CONNECTION WITH THE OFFER. HOWEVER,
SHAREHOLDERS OF THE COMPANY WHO OBJECT TO THE COMPULSORY ACQUISITION SHALL BE
ENTITLED TO FILE A NOTICE OF OBJECTION WITH THE TEL AVIV DISTRICT COURT AND THE
COURT MAY ISSUE RELIEF AS IT SEES FIT.
 
     The Company has informed Purchaser that as of March 7, 1999, there were
12,258,898 Shares issued and outstanding, none of which were owned by Purchaser.
In addition, 950,705 shares were reserved for issuance upon the exercise of
outstanding options (the "Company Options") granted under the stock option plans
of the Company or any subsidiary of the Company (the "Company Option Plans").
The holders of approximately 7,482,500 Shares (or 61.0% of the issued and
outstanding Shares as of the date of the Tender Agreement) have agreed to tender
such Shares pursuant to the Offer pursuant to the Shareholder Agreements
described below. In addition Boole & Babbage, Inc. ("Boole") owned 452,800
Shares as of March 7, 1999.
 
     In accordance with the Tender Agreement, the Company has agreed to hold an
extraordinary general meeting of its shareholders (the "Special Meeting") for
purposes of approving: (i) the right of certain directors of the Company to sell
their Shares to Purchaser pursuant to the Offer, (ii) the right of certain
directors of the Company to receive compensation from the Company against a
release of such directors' claim regarding an alleged promise by the Company to
issue such directors stock options, (iii) a Settlement and Release Agreement,
dated as of March 7, 1999, among the Company, the Principal Shareholders and
certain directors, and (iv) 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 shareholders to the Company (collectively, the
"Shareholder Approvals"). All resolutions, other than the special resolution in
(iv) above, require a majority of the Shares present and voting at the Special
Meeting. The special resolution requires 75% of the Shares present and voting at
the Special Meeting. The Company's Board of Directors has recommended that
shareholders give the Shareholder Approvals at the Special Meeting. Receipt of
the Shareholder Approvals is a condition to the Offer.
 
     In connection with the Offer, the Company has entered into release
agreements dated as of March 7, 1999 (the "Director Releases") under which the
Company has agreed to pay to three directors of the Company, subject to
consummation of the Offer, an aggregate of $7,500,000 (plus value added tax and
less applicable withholding tax) in exchange for a release by such directors of
claims that such directors had for past compensation and all other claims
against the Company.

     Tendering shareholders will not be obligated to pay brokerage fees or
commissions to Goldman, Sachs & Co., as the dealer managers (the "Dealer
Managers"), BankBoston, N.A., as the depositary (the "Depositary"), or MacKenzie
Partners, Inc., as the information agent (the "Information Agent"), or, except
as set forth in Instruction 6 to the Letter of Transmittal, transfer taxes on
the sale of Shares pursuant to the Offer. A tendering shareholder who holds
securities with such shareholder's broker may be required by such broker to pay
a service charge or other fee. Purchaser will pay all charges and expenses of
the Dealer Managers, the Depositary and the Information Agent incurred in
connection with the Offer. See Section 16.
 
     This Offer and the accompanying documents contain information required to
be disclosed by the Securities Exchange Act of 1934, as amended, and the rules
and regulations promulgated thereunder (the "Exchange Act"), including financial
information regarding Company, Purchaser, a description of the terms, conditions
and background of the Offer, and the procedures for tendering Shares for

RESPECT TO THE OFFER.

                                THE TENDER OFFER
 
1. TERMS OF THE OFFER
 
     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), Purchaser will accept for payment (and thereby purchase) and pay
for all Shares that are validly tendered prior to the Expiration Date and not
withdrawn in accordance with Section 4 below promptly after expiration of the
Offer. As used in the Offer, the term "Expiration Date" shall mean 12:00
midnight, New York City time, on Thursday, April 8, 1999, unless and until
Purchaser, in accordance with the terms of the Offer and the Tender Agreement,
shall have extended the period of time during which the Offer is open, in which
event the term "Expiration Date" shall mean the latest time and date at which
the Offer, as so extended by Purchaser or the Company, shall expire.
 
     In the event that the Offer is not consummated, Purchaser may seek to
acquire Shares through open market purchases, privately negotiated transactions,
or otherwise, upon such terms and conditions and at such prices as it shall
determine, which may be more or less than the Offer Price and could be for cash
or other consideration.
 
     The Offer is subject to certain other conditions set forth in Section 14
below. If any condition to Purchaser's obligation to purchase Shares under the
Offer is not satisfied prior to the Expiration Date, Purchaser reserves the
right but is not obligated to, subject to the terms and conditions of the Tender
Agreement: (i) terminate the Offer and decline payment for any Shares tendered,
(ii) amend the Offer as to any Shares not then accepted for payment, or (iii)
delay the acceptance for payment of Shares tendered.
 
     Any extension, amendment or termination will be followed as promptly as
practicable by public announcement thereof in accordance with the public
announcement requirements of Rule 14d-4(c) under the Exchange Act.
 
     Subject to applicable law, Purchaser reserves the right to amend or modify
the terms of the Offer at any time prior to acceptance of the Shares for payment
pursuant to the Offer, except that 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 changes in the terms or conditions of the Offer that is adverse to the
holders of Shares.
 
     If Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer
(including the 90% Condition), Purchaser will disseminate additional tender
offer materials and extend the Offer to the extent required by Rules 14d-4(c),
14d-6(d) and 14e-1 under the Exchange Act. The minimum period during which an
offer must remain open following a material change in the terms of the offer or
information concerning the offer, other than a change in price or a change in
the percentage of securities sought, will depend upon the facts and
circumstances then existing, including the relative materiality of the changed
terms or information. In a public release, the United States Securities and
Exchange Commission (the "Commission") has stated that in its view an offer must
remain open for a minimum period of time following a material change in the
terms of the Offer and that waiver of a material condition, such as the 90%
Condition, is a material change in the terms of the Offer. The release states
that an offer should remain open for a minimum of five business days from the
date a material change is first published, sent or given to security holders and
that, if material changes are made with respect to information not materially
less significant than the offer price and the number of Shares being sought, a
minimum of ten business days may be required to allow adequate dissemination and
investor response. The requirement to extend the Offer will not apply to the
extent that the number of business days remaining between the occurrence of the
change and the then-scheduled Expiration Date equals or exceeds the minimum
extension period that would be required because of such amendment. If, prior to
the Expiration Date, Purchaser increases the consideration to be paid per Share
pursuant to the Offer, Purchaser will pay such increased consideration for all
Shares purchased pursuant to the Offer, whether or not such Shares were tendered
prior to such increase in consideration. As used in this Offer to Purchase,
"business day" has the meaning set forth in Rule 14d-1(e)(6) under the Exchange
Act.

     Purchaser reserves the right, subject to applicable laws (including
applicable regulations of the Commission promulgated under the Exchange Act) and
to the terms of the Tender Agreement, at any time or from time to time, to: (i)
delay acceptance for payment of or payment for any Shares, regardless of whether
the Shares were theretofore accepted for payment, or (ii) terminate the Offer
and not accept for payment or pay for any Shares not theretofore accepted for
payment or paid for, in each case upon the occurrence of any of the conditions
specified in Section 14 below. The reservation by Purchaser of the right to
delay acceptance for payment of or payment for Shares is subject to the
provisions of Rule 14e-1(c) under the Exchange Act, which requires that
Purchaser pay the consideration offered or return the Shares deposited by or on
behalf of shareholders promptly after the termination or withdrawal of the
Offer. Any delay in acceptance for payment or payment beyond the time permitted
by applicable law will be effectuated by an extension of the period of time
during which the Offer is open.
 
     Any extension, amendment or termination of the Offer, any waiver of any
condition of the Offer, or any delay in payment, will be followed as promptly as
practicable by a public announcement. In the case of an extension, Rule 14e-1(d)
under the Exchange Act requires that the announcement be issued no later than
9:00 a.m., New York City time, on the next business day after the previously
scheduled expiration date in accordance with the public announcement
requirements of Rule 14d-4(c) under the Exchange Act. Subject to applicable law
(including Rules 14d-4(c) and 14d-6(d) under the Exchange Act, which require
that any material change in the information published, sent or given to
shareholders in connection with an offer be promptly disseminated to
shareholders in a manner reasonably designed to inform shareholders of such
change), and without limiting the manner in which Purchaser may choose to make
any public announcement, Purchaser will not have any obligation to publish,
advertise or otherwise communicate any such public announcement other than by
making a release to the Dow Jones New Service (or a similar news service) or as
otherwise may be required by law. During any extension of the Offer, all Shares
previously tendered and not properly withdrawn will remain subject to the Offer,
subject to the rights of a tendering shareholder to withdraw its Shares in
accordance with the procedures set forth in Section 4. PURCHASER SHALL NOT HAVE
ANY OBLIGATION TO PAY INTEREST ON THE PURCHASE PRICE FOR TENDERED SHARES,
WHETHER OR NOT PURCHASER EXERCISES ITS RIGHT TO EXTEND THE OFFER.
 
     The Company has provided Purchaser with its shareholder list and security
position listings for the purpose of disseminating the Offer to shareholders.
This Offer to Purchase, the related Letter of Transmittal and other relevant
materials will be mailed to record holders of Shares and will be furnished to
brokers, dealers, commercial banks, trust companies and similar persons whose
names, or the names of whose nominees, appear on the Company's shareholder list,
or, if applicable, who are listed as participants in a clearing agency's
security position listing, for subsequent transmittal to beneficial owners of
Shares.
 
2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES
 
     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), Purchaser will accept for payment (and thereby purchase) and pay
for, as soon as practicable after the Expiration Date, all Shares validly
tendered prior to the Expiration Date and not properly withdrawn in accordance
with the procedures set forth in Section 4. Purchaser expressly reserves the
right, in its discretion, subject to applicable laws and regulations, to delay
acceptance for payment of or payment for Shares in order to comply, in whole or
in part, with any applicable law, government regulation or condition contained
herein. See Sections 1 and 14.
 
     Any such delays will be effected in compliance with Rule 14e-1(c)
promulgated under the Exchange Act (relating to a bidder's obligation to pay for
or return tendered securities promptly after the termination or withdrawal of
such bidder's offer).
 
     In all cases, payment for Shares purchased pursuant to the Offer will be
made only after timely receipt by the Depositary of (i) certificates for such
Shares (or a Book-Entry Confirmation (as defined in Section 3) with respect to
such Shares), (ii) the Letter of Transmittal (or a manually signed facsimile
thereof), properly completed and duly executed, with all required signature
guarantees, or in the case of a book-entry transfer, an
 
                                        5
<PAGE>   8
 
Agent's Message (as defined in Section 3), and (iii) all other documents
required by the Letter of Transmittal. See Section 3 below.
 
     For purposes of the Offer, Purchaser will be deemed to have been accepted
for payment (and thereby purchased) Shares validly tendered prior to the
Expiration Date and not properly withdrawn as, if and when Purchaser gives oral
or written notice to the Depositary of Purchaser's acceptance of such Shares for
payment pursuant to the Offer. Upon the terms and subject to the conditions of
the Offer, payment for Shares purchased pursuant to the Offer will be made by
deposit of the purchase price therefor with the Depositary, which will act as
agent for tendering shareholders for the purpose of receiving payment from
Purchaser and transmitting payment to tendering shareholders whose Shares have
theretofore been accepted for payment. If, for any reason, acceptance for
payment of or payment for any Shares tendered pursuant to the Offer is delayed,
or Purchaser is unable to accept for payment Shares tendered pursuant to the
Offer, then, without prejudice to Purchaser's rights under Section 14, the
Depositary may, nevertheless, on behalf of Purchaser, retain tendered Shares,
and such Shares may not be withdrawn, except to the extent that the tendering
shareholders are entitled to withdrawal rights as described in Section 4 below
and as otherwise required by Rule 14e-l(c) under the Exchange Act. Under no
circumstances will interest on the Offer Price be paid by Purchaser, regardless
of any extension of the Offer or any delay in making such payment.
 
     Upon the deposit of funds with the Depositary for the purpose of making
payments to tendering shareholders, Purchaser's obligation to make such payment
shall be satisfied and tendering shareholders must thereafter look solely to the
Depositary for payment of amounts owed to them by reason of the acceptance for
payment of Shares pursuant to the Offer. Tendering shareholders will not be
obligated to pay brokerage fees or commissions or, except as set forth in
Instruction 6 of the Letter of Transmittal, transfer taxes on the purchase of
Shares pursuant to the Offer. Purchaser will pay any charges and expenses of the
Depositary and the Information Agent.
 
     If any tendered Shares are not purchased for any reason or if certificates
are submitted for more Shares than are tendered, certificates for such Shares
not purchased or tendered will be returned pursuant to the instructions of the
tendering shareholder without expense to the tendering shareholder (or, in the
case of Shares delivered by book-entry transfer, into the Depositary's account
at the Book-Entry Transfer Facility (as defined in Section 3) pursuant to the
procedures set forth in Section 3, such Shares will be credited to an account
maintained at the Book-Entry Transfer Facility) as promptly as practicable
following the expiration, termination or withdrawal of the Offer.
 
     If, prior to the Expiration Date, Purchaser increases the consideration to
be paid per Share pursuant to the Offer, Purchaser will pay such increased
consideration for all such Shares purchased pursuant to the Offer, whether or
not such Shares were tendered prior to such increase in consideration.
 
     Purchaser reserves the right to assign, in its sole discretion, to any
newly-formed direct wholly owned subsidiary of Purchaser the right to purchase
Shares tendered pursuant to the Offer; however, no such transfer or assignment
will release Purchaser from its obligations under the Offer or prejudice the
rights of tendering shareholders to receive payment for Shares validly tendered
and accepted for payment pursuant to the Offer.
 
3. PROCEDURE FOR TENDERING SHARES
 
     Valid Tenders. For Shares to be validly tendered pursuant to the Offer,
either (a) a properly completed and duly executed Letter of Transmittal (or a
manually signed facsimile thereof), with all required signature guarantees, or
an Agent's Message in connection with a book-entry delivery of Shares, and all
other documents required by the Letter of Transmittal, must be received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase prior to the Expiration Date and either (i) certificates representing
such Shares must be received by the Depositary at any such address prior to the
Expiration Date or (ii) such Shares must be delivered pursuant to the procedures
for book-entry transfer set forth below and a Book-Entry Confirmation (as
defined below) must be received by the Depositary prior to the Expiration Date
or (b) the tendering shareholder must comply with the guaranteed delivery
procedures set forth below prior to the Expiration Date. No alternative,
conditional or contingent tenders will be accepted.
 
                                        6

     Book-Entry Transfer. The Depositary will establish an account with respect
to the Shares at the Depository Trust Company (the "Book-Entry Transfer
Facility") for purposes of the Offer within two business days after the date of
this Offer to Purchase. Any financial institution that is a participant in the
Book-Entry Transfer Facility's system may make book-entry delivery of Shares by
causing the Book-Entry Transfer Facility to transfer such Shares into the
Depositary's account at the Book-Entry Transfer Facility in accordance with the
Book-Entry Transfer Facility's procedures for such transfer. However, although
delivery of Shares may be made through book-entry transfer into the Depositary's
account at the Book-Entry Transfer Facility, the Letter of Transmittal (or a
manually signed facsimile thereof), properly completed and duly executed, with
all required signature guarantees, or an Agent's Message in connection with a
book-entry delivery of Shares, and all other required documents, must in any
case, be transmitted to, and received by, the Depositary at one of its addresses
set forth on the back cover of this Offer to Purchase prior to the Expiration
Date, or the tendering shareholder must comply with the guaranteed delivery
procedures described below. The confirmation of a book-entry transfer of Shares
into the Depositary's account at the Book-Entry Transfer Facility as described
above is referred to herein as a "Book-Entry Confirmation." DELIVERY OF
DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH THE BOOK-ENTRY
TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
     The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares which are the subject of such Book-Entry
Confirmation, that such participant has received and agrees to be bound by the
terms of the Letter of Transmittal and that Purchaser may enforce such agreement
against the participant.
 
     Signature Guarantees. Except as otherwise provided below, all signatures on
a Letter of Transmittal must be guaranteed by a financial institution which is a
member of the Medallion Signature Guarantee Program, or by any other "eligible
guarantor institution," as such term is defined in Rule 17Ad-15 under the
Exchange Act (each an "Eligible Institution"). Signatures on a Letter of
Transmittal need not be guaranteed (a) if the Letter of Transmittal is signed by
the registered holders (which term, for purposes of this section, includes any
participant in the Book-Entry Transfer Facility's system whose name appears on a
security position listing as the owner of the Shares) of Shares tendered
therewith and such registered holder has not completed the box entitled "Special
Payment Instructions" or the box entitled "Special Delivery Instructions" on the
Letter of Transmittal or (b) if such Shares are tendered for the account of an
Eligible Institution. See Instructions 1 and 5 of the Letter of Transmittal. If
the certificates representing Shares are registered in the name of a person
other than the signer of the Letter of Transmittal or if certificates for Shares
not accepted for payment or not tendered are to be issued to a person other than
the registered holder, then the certificates must be endorsed or accompanied by
duly executed stock powers, in each case signed exactly as the name or names of
the registered holder or holders appear on the certificates, with the signatures
on the certificates or stock powers guaranteed as described above and as
provided in the Letter of Transmittal. See Instructions 1 and 5 of the Letter of
Transmittal.
 
     Guaranteed Delivery. If a shareholder desires to tender Shares pursuant to
the Offer and such shareholder's certificates are not immediately available or
the procedures for book-entry transfer cannot be completed on a timely basis or
time will not permit all required documents to reach the Depositary prior to the
Expiration Date, such Shares may nevertheless be tendered if all of the
following guaranteed delivery procedures are complied with:
 
          (i) such tender is made by or through an Eligible Institution;
 
          (ii) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form provided by Purchaser herewith, is
     received by the Depositary as provided below prior to the Expiration Date;
     and
 
          (iii) the certificates for all tendered Shares in proper form for
     transfer or a Book-Entry Confirmation with respect to all tendered Shares,
     together with a properly completed and duly executed Letter of Transmittal
     (or a manually signed facsimile thereof) and all required signature
     guarantees (or in the case
                                        7
<PAGE>   10
 
     of a book-entry transfer, an Agent's Message) and all other documents
     required by the Letter of Transmittal, are received by the Depositary
     within three trading days after the date of execution of such Notice of
     Guaranteed Delivery. A "trading day" is any day on which the Nasdaq
     National Market is open for business.
 
     THE NOTICE OF GUARANTEED DELIVERY MAY BE DELIVERED BY HAND OR TRANSMITTED
BY FACSIMILE TRANSMISSION OR MAILED TO THE DEPOSITARY AND MUST INCLUDE A
GUARANTEE BY AN ELIGIBLE INSTITUTION IN THE FORM SET FORTH IN SUCH NOTICE OF
GUARANTEED DELIVERY.
 
     Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer in all cases will be made only after timely
receipt by the Depositary of (a) certificates for (or a Book-Entry Confirmation
with respect to) such Shares, (b) a Letter of Transmittal (or a manually signed
facsimile thereof), properly completed and duly executed, with all required
signature guarantees (or in the case of a book-entry transfer, an Agent's
Message) and (c) all other documents required by the Letter of Transmittal.
Accordingly, tendering shareholders may be paid at different times depending
upon when the foregoing materials are actually received by the Depositary. Under
no circumstances will interest on the purchase price be paid by Purchaser,
regardless of any extension of the Offer or any delay in making such payment.
 
     The method of delivery of certificates for Shares, the Letter of
Transmittal and any other required documents (including delivery through the
Book-Entry Transfer Facility) is at the option and sole risk of the tendering
shareholder and delivery will be deemed made only when actually received by the
Depositary. If delivery is by mail, registered mail with return receipt
requested, properly insured, is recommended. In all cases, sufficient time
should be allowed to ensure timely delivery. SHARES TENDERED BY GUARANTEED
DELIVERY FOR WHICH SHARE CERTIFICATES ARE NOT RECEIVED BY THE DEPOSITARY PRIOR
TO OR ON THE EXPIRATION DATE WILL NOT BE COUNTED AS SHARES TENDERED FOR PURPOSES
OF CALCULATING WHETHER THE 90% CONDITION HAS BEEN SATISFIED.
 
     Determination of Validity. All questions as to the form of documents and
the validity, eligibility (including time of receipt) and acceptance for payment
of any tender of Shares pursuant to any of the procedures described above will
be determined by Purchaser in its sole discretion, which determination shall be
final and binding on all parties. Purchaser reserves the absolute right to
reject any or all tenders of Shares determined not to be in proper form or the
acceptance of or payment for which may, in the opinion of counsel, be unlawful
and reserves the absolute right (but shall not be obligated) to waive any defect
or irregularity in any tender of Shares. Subject to the terms of the Tender
Agreement, Purchaser also reserves the absolute right (but shall not be
obligated) to waive or to amend any of the conditions of the Offer or any defect
or irregularity in any tender with respect to Shares of any particular
shareholder, whether or not similar defects or irregularities are waived in the
case of other shareholders. No tender of Shares will be deemed to have been
validly made until all defects and irregularities have been cured or waived.
Purchaser's interpretation of the terms and conditions of the Offer (including
the Letter of Transmittal and the instructions thereto) will be final and
binding on all parties. None of Purchaser, the Dealer Manager, the Depositary,
the Information Agent or any other person will be under any duty to give
notification of any defects or irregularities in tenders or incur any liability
for failure to give any such notification.
 
     Other Requirements. By executing and delivering a Letter of Transmittal, a
tendering shareholder irrevocably appoints designees of Purchaser as such
shareholder's attorneys-in-fact and proxies, each with full power of
substitution, in the manner set forth in the Letter of Transmittal, to the full
extent of such shareholder's rights with respect to the Shares tendered by such
shareholder and accepted for payment by Purchaser and with respect to any and
all other distributions, rights, Shares or other securities issued or issuable
in respect of such Shares, on or after the date of the Tender Agreement. All
such powers of attorney and proxies shall be considered coupled with an interest
in the tendered Shares and therefore irrevocable. Such appointment will be
effective when, and only to the extent that Purchaser accepts such Shares for
payment pursuant to the Offer. Upon such acceptance for payment, all prior
powers of attorney and proxies given by such shareholder with respect to such
Shares (and any other securities so issued in respect of such purchased Shares)
will be revoked, without further action, and no subsequent powers of attorney
and proxies may be given by such shareholder with respect thereto (and, if
given, will not be deemed effective). The designees of Purchaser will be
empowered to exercise all voting and other rights of such shareholder with
 
                                        8
<PAGE>   11
 
respect to such Shares (and any other securities so issued in respect of such
purchased Shares) as they in their sole discretion may deem proper, including,
without limitation, in respect of any general meeting of the shareholders, or
any adjournment or postponement thereof, in connection with any action by
written consent in lieu of a meeting or otherwise. Purchaser reserves the
absolute right to require that, in order for Shares to be validly tendered,
immediately upon Purchaser's acceptance for payment of such Shares, Purchaser or
its designees must be able to exercise full voting and other rights with respect
to such Shares (and any other securities so issued in respect of such purchased
Shares), including, without limitation, the right to vote at any meeting of
shareholders then scheduled.
 
     A tender of Shares pursuant to any of the procedures described above will
constitute the tendering shareholder's acceptance of the terms and conditions of
the Offer, as well as the tendering shareholder's representation and warranty
that (i) such shareholder has the full power and authority to tender, sell,
assign and transfer the tendered Shares (and any and all other Shares or other
securities issued or issuable in respect of such Shares on or after March 11,
1999), and (ii) when the same are accepted for payment by Purchaser, Purchaser
will acquire good, marketable and unencumbered title thereto, free and clear of
all liens, restrictions, charges and encumbrances and not subject to any adverse
claim. Purchaser's acceptance for payment of Shares tendered pursuant to the
Offer will constitute a binding agreement between the tendering shareholder and
Purchaser upon the terms and subject to the conditions of the Offer.
 
     Backup Federal Income Tax Withholding. To prevent backup U.S. federal
income tax withholding of 31% of the payments made to a shareholder with respect
to the purchase price of Shares acquired pursuant to the Offer, such shareholder
must provide the Depositary with such shareholder's correct taxpayer
identification number and certify that such shareholder is not subject to backup
federal income tax withholding by completing the Substitute Form W-9 included in
the Letter of Transmittal. See instruction 11 of the Letter of Transmittal and
Section 5 below. If the shareholder is a nonresident alien or foreign entity not
subject to back-up withholding, the shareholder must give the Depositary a
completed Form W-8 Certificate of Foreign Status prior to receipt of any
payments.
 
4. WITHDRAWAL RIGHTS
 
     Tenders of Shares made pursuant to the Offer are irrevocable, except as
otherwise provided in this Section 4. Shares tendered pursuant to the Offer may
be withdrawn at any time prior to the Expiration Date and, unless theretofore
accepted for payment by Purchaser as provided herein, may also be withdrawn at
any time after May 9, 1999. If Purchaser extends the Offer, is delayed in its
purchase of or payment for Shares or is unable to purchase or pay for Shares for
any reason, then, without prejudice to the rights of Purchaser under the Offer,
tendered Shares may be retained by the Depositary on behalf of Purchaser and may
not be withdrawn except to the extent that tendering shareholders are entitled
to withdrawal rights as set forth in this Section 4.
 
     The reservation by Purchaser of the right to delay the acceptance or
purchase of or payment for Shares is subject to the provisions of Rule 14e-l(c)
under the Exchange Act, which requires Purchaser to pay the consideration
offered or return Shares deposited by or on behalf of shareholders promptly
after the termination or withdrawal of the Offer.
 
     For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase. Any
such notice of withdrawal must specify the name of the person who tendered the
Shares to be withdrawn, the number of Shares to be withdrawn and the name of the
registered holder, if different from that of the person who tendered such
Shares. If certificates evidencing Shares to be withdrawn have been delivered or
otherwise identified to the Depositary, then prior to the release of such
certificates, the tendering shareholder must also submit the serial numbers
shown on the particular certificates evidencing the Shares to be withdrawn, and
the signature on the notice of withdrawal must be guaranteed by an Eligible
Institution (except in the case of Shares tendered for the account of an
Eligible Institution). If Shares have been tendered pursuant to the procedures
for book-entry transfer set forth in Section 3, the notice of withdrawal
 
                                        9
<PAGE>   12
 
must specify the name and number of the account at the Book-Entry Transfer
Facility to be credited with the withdrawn Shares and otherwise comply with the
Book-Entry Transfer Facility's procedures.
 
     All questions as to form and validity (including time of receipt) of
notices of withdrawal will be determined by Purchaser, in its sole discretion,
whose determination shall be final and binding on all parties. No withdrawal of
Shares shall be deemed to have been properly made until all defects and
irregularities have been cured or waived. None of Purchaser, the Dealer Manager,
the Depositary, the Information Agent or any other person will be under any duty
to give notification of any defects or irregularities in any notice of
withdrawal or incur any liability for failing to give such notification.
 
     Any Shares properly withdrawn will be deemed not validly tendered for
purposes of the Offer, but may be tendered at any subsequent time prior to the
Expiration Date by following any of the procedures described in Section 3 above.
 
5. CERTAIN FEDERAL AND ISRAELI LAW TAX CONSEQUENCES OF THE OFFER
 
U.S. Federal Income Tax Consequences to U.S. Holders.
 
     The following discussion summarizes the United States federal income tax
consequences to U.S. Holders (as defined below) of the receipt of cash in
exchange for Shares. The discussion is based on the Internal Revenue Code of
1986, as amended (the "Code"), Treasury regulations, judicial decisions and
published positions of the Internal Revenue Service (the "IRS"), all as in
effect on the date hereof, and all of which are subject to change, possibly with
retroactive effect. This discussion does not address all aspects of U.S. federal
income taxation (including potential application of the alternative minimum tax)
that may be relevant to a particular U.S. Holder based on such holder's
particular circumstances and does not address any aspect of state, local or
non-U.S. tax laws. Further, this summary generally considers only U.S. Holders
that hold the Shares as capital assets (generally, assets held for investment)
and may not apply to all U.S. Holders. In particular, the discussion may not
apply to U.S. Holders (i) who acquired their Shares pursuant to the exercise of
employee stock options or other compensation arrangements with the Company; (ii)
who are subject to special tax treatment under the Code (such as broker-dealers,
insurance companies, tax-exempt organizations, financial institutions, and
regulated investment companies); (iii) who hold the Shares as part of a
"straddle," "hedge," or "conversion transaction," or whose functional currency
is not the U.S. dollar; (iv) who own, or have owned, directly, indirectly, or
through attribution, currently or during the past five years, 10% or more of the
Shares; or (v) who are certain expatriates or former long-term residents of the
U.S.
 
     For purposes of this discussion, a "U.S. Holder" is any holder of Shares
who is (i) a citizen or resident of the U.S.; (ii) a corporation or other entity
taxable as a corporation organized under the laws of the U.S. or of any state
thereof or the District of Columbia; (iii) an estate the income of which is
included in gross income for U.S. federal income tax purposes regardless of
source; (iv) a trust, if a U.S. court is able to exercise primary supervision
over its administration and one or more U.S. persons have the authority to
control all of its substantial decisions; or (v) any other person who is subject
to U.S. federal income tax on a net income basis with respect to the Shares. In
the case of a holder of Shares that is a partnership for U.S. federal income tax
purposes, each partner of such partnership will take into account its allocable
share of income or loss from the Shares, and will take such income or loss into
account under the rules of taxation applicable to such partner, taking into
account the activities of the partnership and the partner.
 
     Exchange of Shares for Cash. The receipt of cash by a U.S. Holder in
exchange for its Shares pursuant to the Offer will be a taxable transaction for
U.S. federal income tax purposes. A U.S. Holder will recognize gain or loss for
U.S. federal income tax purposes equal to the difference between its adjusted
tax basis in the Shares and the amount of cash received in exchange for the
Shares pursuant to the Offer. Such gain or loss generally will be capital gain
or loss, and will be long term capital gain or loss if the Shares were held for
more than one year. Subject to certain limited exceptions, capital losses cannot
be applied to offset ordinary income for U.S. federal income tax purposes.
 
     In general, any gain or loss recognized by a U.S. Holder on the exchange of
the Shares for cash will be U.S. source income or loss. However, pursuant to the
Income Tax Treaty between the State of Israel and the
 
                                       10
<PAGE>   13
 
United States of America (the "Tax Treaty"), gain from the exchange of the
Shares to a U.S. Holder who is a U.S. resident (for purposes of the Tax Treaty)
and who sells the Shares in Israel may be treated as foreign-source gain for
purposes of the foreign tax credit limitation.
 
     Backup Withholding. Payments in connection with the Offer may be subject to
"backup withholding" at a 31% rate. Backup withholding generally applies if the
U.S. Holder (a) fails to furnish his social security number or other taxpayer
identification number ("TIN"), (b) furnishes an incorrect TIN, (c) fails
properly to report interest or dividends or (d) under certain circumstances,
fails to provide a certified statement, signed under penalties of perjury, that
the TIN provided is his correct number and that he is not subject to backup
withholding. Backup withholding is not an additional tax but merely an advance
payment, which may be refunded to the extent it results in an overpayment of
tax. Any amounts withheld from a payment to a U.S. Holder under the backup
withholding rules will be allowed as a credit against such holder's federal
income tax liability, provided that the required information is provided to the
Internal Revenue Service; alternatively, the U.S. Holder may be eligible for a
refund of any excess amounts withheld under the backup withholding rules.
Certain persons generally are exempt from backup withholding, including
corporations, financial institutions and non-U.S. Holders. Certain penalties
apply for failure to furnish correct information and for failure to include the
reportable payments in income. Holders of Shares who are not U.S. Holders will
be exempt from backup withholding if such persons certify as to their foreign
status on an I.R.S. Form W-8. Each shareholder should consult with such
shareholder's own tax advisor as to such shareholder's qualification for
exemption from withholding and the procedure for obtaining such exemption.
 
Certain Israeli Tax Considerations
 
     The following is a summary of certain Israeli tax considerations applicable
to the Company's shareholders in connection with the receipt of cash in exchange
for Shares pursuant to the Offer. The following summary is not intended and
should not be construed as legal or professional tax advice and does not cover
all possible tax considerations. The following summary is addressed only to
shareholders that hold the Shares as capital assets (generally, assets held for
investment) and may not apply to all shareholders. In particular, this
discussion does not apply to shareholders who acquire Shares pursuant to the
exercise of employee stock options or other compensation arrangements with the
Company.
 
     Under existing Israeli regulations, any capital gain realized by a holder
with respect to the Shares will generally be exempt from Israeli capital gains
tax provided, that (i) the Company qualifies as an "industrial company" within
the meaning of the Law for the Encouragement of Industry (Taxes), 5729-1969, of
the State of Israel and (ii) the Shares are listed on the Nasdaq National
Market. The Shares are currently listed on the Nasdaq National Market, and the
Purchaser has received a confirmation from the auditors of the Company that the
Company qualifies as an "industrial company". Therefore, persons who dispose of
Shares pursuant to the Offer or prior to the completion of the Offer will be
exempt from Israeli capital gains tax in connection with such dispositions. This
exemption does not apply to individuals who are defined as "traders" in
securities under the Israeli Income Tax Ordinance or to persons (both individual
or corporate) that are subject to the Israeli Income Tax Law (Adjustment to
Inflation), 1985. Holders of Shares other than Treaty U.S. Residents (as defined
below), whose Shares are acquired pursuant to the Compulsory Acquisition, may,
subject to any applicable income tax treaty, in the event that such acquisition
takes place after the delisting of the Company from the Nasdaq National Market,
be subject to Israeli capital gains taxation in connection with such disposition
at the rate of 36% for corporate shareholders and 50% for individual
shareholders.
 
     Under the Tax Treaty, persons who qualify as "residents of the United
States" as defined in the Tax Treaty ("Treaty U.S. Residents"), and who owned,
both directly and indirectly, less than 10% of the Company's outstanding voting
shares during the 12 month period prior to the disposition of their Shares
(whether such disposition takes place pursuant to the Offer, the Compulsory
Acquisition or otherwise) will be exempt from Israeli tax in connection with
such disposition.
 
     Backup Withholding. As mentioned above under "U.S. Federal Income Tax
Consequences to U.S. Holders -- Backup Withholding", payment in connection with
the Offer may be subject to backup
 
                                       11
<PAGE>   14
 
withholding at a rate of 31%. Holders of Shares that are not U.S. Holders will
be exempt from backup withholding if such persons certify as to their foreign
status on an I.R.S. Form W-8.
 
     THE ABOVE SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL
TAX CONSEQUENCES RELATING TO THE DISPOSITION OF SHARES. HOLDERS OF SHARES ARE
URGED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE TAX CONSEQUENCES OF THEIR
PARTICULAR SITUATIONS.
 
6. PRICE RANGE OF THE SHARES; DIVIDENDS ON THE SHARES
 
     The Shares are traded in the over-the-counter market and prices are quoted
on the Nasdaq National Market ("Nasdaq") under the symbol "DDDDF." The following
table sets forth, for the periods indicated, the high and low bid prices per
Share on Nasdaq as reported by the Dow Jones News Retrieval Service.

FISCAL YEAR 1997:
  First Quarter.............................................  $14.13   $ 8.00
  Second Quarter............................................   13.88     9.13
  Third Quarter.............................................   22.88    13.00
  Fourth Quarter............................................   22.38    15.88
FISCAL YEAR 1998:
  First Quarter.............................................  $26.63   $18.75
  Second Quarter............................................   35.38    21.25

  Fourth Quarter............................................   49.00    18.25
FISCAL YEAR 1999:
  First Quarter (through March 10, 1999)....................   58.88    41.88
</TABLE>
 
     On March 5, 1999, the last full trading day before the public announcement
of Purchaser's intention to acquire the Shares, the closing bid price per Share
on Nasdaq was $48.94. On March 10, 1999, the last full trading day before the
commencement of the Offer, the closing bid price per Share on Nasdaq was $51.56
per Share. SHAREHOLDERS ARE URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR THE
SHARES.
 
     According to the Company, the Company has never paid dividends on the
Shares and does not anticipate a change in this policy in the foreseeable
future. In addition, the payment of dividends is restricted under the terms of
the Tender Agreement.
 
7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; NASDAQ NATIONAL MARKET
   LISTING AND EXCHANGE ACT REGISTRATION; MARGIN REGULATIONS
 
     Market for the Shares. The purchase of Shares by Purchaser pursuant to the
Offer will reduce the number of Shares that might otherwise trade publicly and
will reduce the number of holders of Shares, which could adversely affect the
liquidity and market value of the remaining Shares held by the public.
 
     Nasdaq National Market Listing and Exchange Act Registration. Depending
upon the number of Shares purchased pursuant to the Offer, the Shares may no
longer meet the requirements of Nasdaq for continued listing and may be delisted
from Nasdaq. According to Nasdaq's published guidelines, Nasdaq would consider
delisting the Shares if, among other things, the number of holders of at least
100 Shares should fall below 400, the number of publicly held Shares (exclusive
of holdings of officers, directors any other person who is the beneficial owner
of more than 10% of the total Shares outstanding ("Nasdaq Excluded Holdings"))
should fall below 750,000 or the aggregate market value of publicly held Shares
(exclusive of Nasdaq Excluded Holdings) should fall below $5,000,000. If, as a
result of the purchase of Shares pursuant to the Offer or otherwise, the Shares
no longer meet the requirements of Nasdaq for continued listing and the listing
of the Shares is discontinued, the market for the Shares could be adversely
affected.
 
     If Nasdaq were to delist the Shares, it is possible that the Shares would
continue to trade in the over-the-counter market and that price or other
quotations would be reported by other sources. The extent of the public
 
                                       12
<PAGE>   15
 
market therefor and the availability of such quotations would depend, however,
upon such factors as the number of shareholders and/or the aggregate market
value of such securities remaining at such time, the interest in maintaining a
market in the Shares on the part of securities firms, the possible termination
of registration under the Exchange Act as described below, and other factors.
Purchaser cannot predict whether the reduction in the number of Shares that
might otherwise trade publicly would have an adverse or beneficial effect on the
market price for or marketability of the Shares or whether it would cause future
market prices to be greater or less than the Offer Price.
 
     The Shares are currently registered under the Exchange Act. Such
registration may be terminated upon application by the Company to the Commission
if the Shares are not listed on a national securities exchange and there are
fewer than 300 record holders. The termination of the registration of the Shares
under the Exchange Act would substantially reduce the information required to be
furnished by the Company to holders of Shares and to the Commission and would
make certain provisions of the Exchange Act, including the requirement of
furnishing an annual report to shareholders and the requirements of Rule 13e-3
under the Exchange Act with respect to "going private" transactions, no longer
applicable to the Shares. In addition, "affiliates" of the Company and persons
holding "restricted securities" of the Company may be deprived of the ability to
dispose of such securities pursuant to Rule 144 or Rule 144A promulgated under
the Securities Act of 1933, as amended. If registration of the Shares under the
Exchange Act were terminated, the Shares would no longer be "margin securities"
or be eligible for Nasdaq reporting.
 
     PURCHASER INTENDS TO SEEK TO CAUSE THE COMPANY TO APPLY FOR DELISTING OF
THE SHARES FROM NASDAQ AND TERMINATE THE REGISTRATION OF THE SHARES UNDER THE
EXCHANGE ACT AS SOON AFTER THE COMPLETION OF THE OFFER AS THE REQUIREMENTS FOR
SUCH DELISTING AND TERMINATION ARE MET. IF REGISTRATION OF THE SHARES IS NOT
TERMINATED PRIOR TO THE COMPULSORY ACQUISITION, THE REGISTRATION OF THE SHARES
UNDER THE EXCHANGE ACT WILL BE TERMINATED FOLLOWING CONSUMMATION OF THE
COMPULSORY ACQUISITION.
 
     Margin Regulations. The Shares are currently "margin securities," as such
term is defined under the rules of the Board of Governors of the Federal Reserve
System (the "Federal Reserve Board"), which has the effect, among other things,
of allowing brokers to extend credit using such securities as collateral.
Depending upon factors similar to those described above regarding listing and

     A copy of this Offer to Purchase and certain of the agreements referred to

the manner set forth above.
 
     The name, business address, present principal occupation or employment,
five-year employment history and citizenship of each director and executive
officer of Purchaser is set forth on Schedule I.
 
     As a result of the options and irrevocable proxy granted to Purchaser under
the Shareholder Agreements, Purchaser may be deemed to share voting and
investment control over, and thus beneficially own, the Shares that are covered
by such Shareholder Agreements, which represent in the aggregate 7,482,500
Shares or 61.0% of the issued and outstanding Shares as of the date of the
Tender Agreement, based on information provided to Purchaser by the Company in
the Tender Agreement. Purchaser disclaims beneficial ownership of such Shares.
In addition, Purchaser has entered into an Agreement and Plan of Reorganization,
dated as of October 31, 1998, among Boole, Purchaser and a subsidiary of
Purchaser (the "Boole Merger Agreement"). Under the Boole Merger Agreement, upon
satisfaction of the conditions to closing thereunder, including
 
                                       16
<PAGE>   19
 
approval by the Boole shareholders, Boole will be acquired by Purchaser by means
of a merger (the "Boole Merger"). The closing of the Boole Merger is expected to
occur as soon as possible after receipt of Boole shareholder approval at a
special meeting of Boole shareholders scheduled for March 30, 1999. Such closing
will be subject to obtaining such approval and to certain other conditions, and
no assurance can be given that such closing will occur. Boole has advised
Purchaser that it owns an aggregate of 452,800 Shares, representing
approximately 3.7% of the issued and outstanding Shares as of the date of the
Tender Agreement. In the Tender Agreement, Purchaser has agreed to use its
reasonable efforts to cause Boole to tender such Shares into the Offer. If the
Boole Merger closes before the Offer expires, Purchaser will be deemed to own
such shares.
 
     Except as set forth in this Offer to Purchase, neither Purchaser nor, to
its knowledge any of the persons listed in Schedule I or any associate or
majority owned subsidiary of any such persons, beneficially owns or has a right
to acquire any equity security of the Company. Except as set forth in this Offer
to Purchase, neither Purchaser nor, to its knowledge, any of their respective
directors, executive officers or subsidiaries has effected any transaction in
any equity security of the Company during the past 60 days.
 
     Except as set forth in this Offer to Purchase, (i) neither Purchaser nor,
to its knowledge, any of the persons listed in Schedule I has any contract,
arrangement, understanding or relationship (whether or not legally enforceable)
with any other person with respect to any securities of the Company, including,
but not limited to, any contract, arrangement, understanding or relationship
concerning the transfer or the voting of any such securities, joint ventures,
loan or option arrangements, puts or calls, guaranties of loans, guaranties
against loss, or the giving or withholding of proxies; (ii) there have been no
contacts, negotiations or transactions between Purchaser, or any of its
subsidiaries or, to its knowledge any of the persons listed on Schedule I on the
one hand, and the Company or any of its directors, officers or affiliates, on
the other hand, that are required to be disclosed pursuant to the rules and

10. SOURCE AND AMOUNT OF FUNDS
 
     THE OFFER IS NOT CONDITIONED ON FINANCING.
 
     The total amount of funds required by Purchaser to consummate the Offer
(including cash payments related to the cancellation of outstanding Company
Options) and the Compulsory Acquisition and to pay related fees and expenses is

capital and loans from U.S. banks. The Purchaser 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

the Proposed Lenders, copies of which are attached as an exhibit to the Schedule
14D-1. 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 Purchaser, which will enable the
Purchaser to convert the revolving loans into a one-year term loan, and (b) a
competitive bid facility which will enable Purchaser to request bids from the
Proposed Lenders for loans on a negotiated basis up to the existing availability
under the Proposed Credit Facility. If Purchaser 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 Purchaser.
 
     The Proposed Credit Facility will include, among others, covenants
regarding the maintenance of: (a) at least $300,000,000 in cash and marketable
securities by the Purchaser and (b) certain financial ratios.
 
                                       17
<PAGE>   20
 
     The Proposed Credit Facility requires the Purchaser 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.
 
     The Proposed Credit Facility will also contain other typical and customary
covenants usually found in commercial bank credit agreements as well as
customary events of default.
 
     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 Purchaser and its subsidiaries.
 
     The Offer is not conditioned on consummation of the Proposed Credit
Facility.
 
11. BACKGROUND OF THE OFFER
 
     Set forth below is a description of the background of the Offer.
 
     On November 2, 1998, Purchaser announced the execution of the Boole Merger
Agreement. Boole develops and markets enterprise automation software solutions
for managing service levels in multivendor, distributed computing environments.
Purchaser believes that its acquisition of Boole, which is subject to
shareholder approval at a special meeting of the Boole shareholders scheduled
for March 30, 1999, will allow Purchaser to provide a foundation for the next
generation of the two companies' systems management software tools for mainframe
and distributed information systems.
 
     While Purchaser has been aware of the Company for years, Purchaser began to
focus on the Company and its software product offerings through the course of
its negotiations with Boole. Boole has been the exclusive distributor of the
Company's products in Europe since March 10, 1987 under an exclusive
distribution agreement between the Company and Boole & Babbage Europe ("BBE"),
an Irish corporation and Boole's European distribution subsidiary (the
"Distribution Agreement"). The Distribution Agreement expires on December 31,
2000; however, announcement of the Boole Merger Agreement triggered an early
termination right that allows the Company to terminate the Distribution
Agreement prior to such expiration. Immediately following the announcement of
the Merger Agreement, BBE's president, Han Bruggeling, arranged a meeting in
Europe among Rick Gardner, Purchaser's Senior Vice President, Worldwide Sales &
Marketing, and senior representatives of the Company. The meeting's purpose was
to explore various possible strategic relationships among Purchaser, Boole and
the Company, including extension or expansion of the distribution arrangement
and Purchaser's acquisition of the Company.
 
     These discussions were continued in a meeting on November 24, 1998 at the
Company's North American headquarters in Irvine, California, in which
Purchaser's senior management reviewed the Company's operations, financial
prospects and products. Following this meeting, the Company's Chief Executive
Officer, Dan Barnea, met in Houston on November 25, 1998 with William Austin,
Purchaser's Senior Vice President and Chief Financial Officer, to discuss the
Company with him. Based on these discussions, Purchaser began its internal
analysis of a possible business combination with the Company and requested
additional information from the Company. On December 18, 1998, Purchaser and the
Company signed a mutual nondisclosure agreement. Purchaser subsequently
submitted its first request for due diligence information about the Company.
Purchaser and the Company signed an additional nondisclosure agreement on
January 6, 1999.
 
     On January 19 and 20, 1999 Purchaser's senior management met with the
Company's senior management in San Francisco, California to review the requested
information. Although this meeting was productive, Purchaser concluded that it
required significant additional information before it could determine whether to
proceed with negotiations to acquire the Company. Much of this information was
financial and technical product information residing in Israel, so Purchaser
arranged to send a team of senior management and technical personnel to the
Company's headquarters in Tel Aviv.
 
     This team performed financial and technical due diligence at the Company's
Tel Aviv headquarters on January 28, 29 and 31, 1999. The Company provided
demonstrations of its software product offerings and technical support
capabilities and discussed current and future research and development projects.
 
                                       18
<PAGE>   21
 
Additionally, the team reviewed financial results, financial reporting controls
and practices, sales forecasts and other financial data. Following this trip,
the team of senior management and technical personnel prepared a detailed
analysis of the Company and of a business combination with Purchaser.
Purchaser's senior management presented this analysis to Max Watson, Purchaser's
Chairman, President and Chief Executive Officer, on February 12, 1999. Mr.
Watson then called a meeting of Purchaser's board of directors to review the
possible acquisition.
 
     Purchaser's board of directors met on February 17, 1999 at Purchaser's
Houston, Texas headquarters. Following a presentation by Purchaser's senior
management and Goldman, Sachs & Co., Purchaser's financial advisors, and
detailed discussion of the possible acquisition, the board authorized Purchaser
to proceed with negotiations to acquire the Company in a cash purchase
transaction.
 
     Beginning on February 22, 1999, Purchaser, the Company and the two
principal shareholders of the Company, Einav Computer Systems Ltd. and Yossie
Hollander (the "Shareholders"), and the parties' legal counsel and financial
advisors, engaged in negotiations concerning the Tender Agreement and the
agreements related thereto, including amendments to the Distribution Agreement.
These negotiations were conducted in New York, New York from February 22 through
February 25, 1999 and were continued by telephone on a daily basis through March
7. Numerous important issues arose in the New York discussions, including
Purchaser's requirement of general releases of certain threatened claims against
the Company. Beginning in late February, the Company began to attempt to obtain
these releases. During the week of February 22, 1999, Purchaser also began to
negotiate employment agreements for the Company's Chief Executive Officer, Dan
Barnea, and his senior executive team, to ensure their continued employment.
 
     On February 26, 1999 Purchaser's financial analyst traveled to Irvine,
California to perform financial due diligence respecting the Company's North
American operations and sales and licensing practices. On February 28, 1999,
Purchaser's local counsel in Israel began its legal and financial due diligence
review at the Company's principal headquarters in Tel Aviv. This local due
diligence effort was extensive and was completed on March 7, 1999. On March 4,
1999, Purchaser's financial analyst, accompanied by legal counsel, traveled to
Irvine, California to perform additional financial and legal due diligence
respecting the Company's North American operations.
 
     On March 5, 1999, Purchaser's board of directors met to consider the
proposed Tender Agreement, Shareholder Agreements, related agreements and the
transactions described therein. At Purchaser's board meeting, Purchaser's senior
management presented a financial and product review of the proposed acquisition
and the final results of the due diligence review. Goldman, Sachs & Co.
presented its financial analysis of the transaction, including a review of the
proposed pricing. After reviewing the terms of the Tender Agreement and the
related agreements, Purchaser's board of directors voted unanimously to approve
the Tender Agreement, the related agreements and the transactions contemplated
thereby. Purchaser's board of directors authorized the officers of Purchaser to
finalize negotiations and execute the Tender Agreement and the related
agreements within a specified price range.
 
     Purchaser and the Company reached agreement on the Tender Offer price of
$52.50 on March 6, 1999.
 
     On March 7, 1999, Purchaser, the Company, and the Shareholders, in each
case represented by their legal counsel, resolved all issues that remained
outstanding.
 
     Also on March 7, 1999, the board of directors of the Company met and
unanimously approved the Tender Agreement and related documents.
 
     The Tender Agreement and other related agreements were executed and
delivered by the parties on March 7, 1999. Prior to the opening of the market on
March 8, 1999, Purchaser issued a press release announcing the execution of the
Tender Agreement.

12. PURPOSE OF THE OFFER; PLANS FOR THE COMPANY; TENDER AGREEMENT; SHAREHOLDER
    AGREEMENTS; OTHER AGREEMENTS; RELATED MATTERS
 
  Purpose of the Offer; Plans for the Company
 
     The purpose of the Offer is to acquire control of, and the entire equity
interest in, the Company. The purpose of the Offer is to acquire all Shares not
beneficially owned by Purchaser and its subsidiaries following consummation of
the Offer, or at least enough Shares to complete the Compulsory Acquisition.
Upon the consummation of the Offer and the Compulsory Acquisition, the Company
will become a direct wholly owned subsidiary of Purchaser.
 
     The acquisition of Shares not owned by Purchaser and its subsidiaries has
been structured as a cash tender offer in order to (i) effect a prompt and
orderly transfer of the Company from its shareholders to Purchaser and (ii)
provide shareholders with cash for all of their Shares at a price in excess of
the market price of the Shares on the date hereof. Because the offer contains
the 90% Condition, it will not succeed unless the holders of at least 90% of the
Shares unaffiliated with Purchaser tender their Shares.
 
     Upon consummation of the Offer and Compulsory Acquisition, the Company will
become a privately held corporation. Accordingly, shareholders will not have the
opportunity to participate directly in earnings and growth of the Company after
the consummation of the Offer and will not have any right to vote on corporate
matters.
 
     Purchaser intends, from time to time after the consummation of the Offer,
to evaluate the business and operations of the Company and will take such
actions as it deems appropriate under the circumstances then existing. Purchaser
intends to seek additional information about the Company during the pendency of
the Offer. Thereafter, Purchaser intends to review such information as part of a
comprehensive review of the Company's business, operations, capitalization and
management with a view to maximizing the Company's potential in conjunction with
Purchaser's businesses.
 
     Except as indicated in this Offer to Purchase, Purchaser does not have any
present plans or proposals which relate to or would result in an extraordinary
corporate transaction, such as a merger, reorganization or liquidation,
involving the Company or any of its subsidiaries, a sale or transfer of a
material amount of assets of the Company or any of its subsidiaries or any
material change in the Company's capitalization or dividend policy or any other
material changes in the Company's corporate structure or business.
 
     Purchaser reserves the right to acquire additional Shares following the
expiration of the Offer through private purchases, market transactions, tender
or exchange offers or otherwise on terms and at prices that may be more or less
favorable than those of the Offer or, subject to any applicable legal
restrictions, to dispose of any or all Shares beneficially acquired by
Purchaser.
 
TENDER AGREEMENT
 
     The following is a summary of the material terms of the Share Purchase and
Tender Agreement, dated as of March 7, 1999, by and between Purchaser and
Company (the "Tender Agreement"). This summary is not a complete description of
the terms and conditions thereof and is qualified in its entirety by reference
to the full text thereof, which is incorporated herein by reference and a copy
of which has been filed with the Commission as an exhibit to the Schedule 14D-1.
The Tender Agreement may be examined, and copies thereof may be obtained, as set
forth in Section 9 above.
 
     The Offer. The Tender Agreement provides that as promptly as practicable
(but in no event later than five business days following the public announcement
of the execution of the Tender Agreement), Purchaser is required to commence the
Offer. If, between the date of the Tender Agreement and the date on which Shares
are accepted for payment pursuant to the Offer (the "Closing Date"), the 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, the Offer Price will be adjusted accordingly.
 
     Under the Tender Agreement, Purchaser has expressly reserved 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. However, without the
 
                                       20
<PAGE>   23
 
prior written consent of the Company, Purchaser may not (i) decrease or change
the form of the Offer Price, (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.
 
     The Tender Agreement provides that 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; provided that,
Purchaser may, in accordance with applicable law, extend the Offer if the
conditions to the Offer have not been satisfied. As long as the Company or its
board of directors shall not have asserted any of their rights described below
under "Acquisition Proposals; Fiduciary Exceptions," 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.
 
     The Company has agreed that no Shares held by the Company will be tendered
to Purchaser pursuant to the Offer. However, 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 Section 14.
 
     Company Action; Recommendation of Board of Directors. In executing the
Tender Agreement, the Company consented to the Offer and represented and
warranted that its board of directors has (a) unanimously determined as of the
date of the Tender Agreement 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 (as described below under "Director Releases"), unless the Company's
shareholders shall have approved such right as set forth in the following
paragraph, to recommend acceptance of the Offer and approval by the shareholders
of the matters to be presented at the Special Meeting described below. The
Tender Agreement provides that directors of the Company will not have the right
to tender their Shares in the Offer nor to receive compensation from the Company
pursuant to the Director Releases unless the Company's Shareholders have
approved such right and such compensation as more fully described below in
"--Special Meeting; Shareholder Approval."
 
     Special Meeting; Shareholder Approval. In accordance with the Tender
Agreement, the Company has agreed to hold a Special Meeting for purposes of
approving: (i) the right of certain directors of the Company to sell their
Shares to Purchaser pursuant to the Offer, (ii) the right of certain directors
of the Company to receive compensation from the Company against a release of
such directors' claim regarding an alleged promise by the Company to issue such
directors stock options, (iii) a Settlement and Release Agreement, dated as of
March 7, 1999, among the Company, the Principal Shareholders and certain
directors, and (iv) 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 shareholders to the Company (collectively, the
"Shareholder Approvals"). All resolutions, other than the special resolution in
(iv) above, require a majority of the Shares present and voting at the Special
Meeting. The special resolution requires 75% of the Shares present and voting at
the Special Meeting. The Company's board of directors has recommended that
shareholders give the Shareholder Approvals at the Special Meeting. Receipt of
the Shareholder Approvals is a condition to the Offer.
 
     Board of Directors. Subject to obtaining the Shareholder Approvals,
promptly upon the purchase by Purchaser pursuant to the Offer of such number of
Shares representing 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
 
                                       21
<PAGE>   24
 
Company, and the Company shall, upon request of Purchaser, take all actions
necessary to enable such Purchaser designees to be so elected or appointed.
 
     Options and Other Purchase Rights. The Tender Agreement provides that the
Company will 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 pursuant to
which 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 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 Offer Price and the exercise price per share of
such Company Option, which amount shall be paid by the Company at the time the
Company Option 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. (a
subsidiary of the Company) capital stock rather than Shares of the Company, the
Offer Price used in the foregoing calculation shall be multiplied by 9.085. All
applicable withholding taxes attributable to such payments or to related
distributions shall be deducted from the amounts payable to option holders and
all such taxes attributable to the cancellation of Company Options shall be
withheld from the proceeds received by holders of Company Options in connection
with their cancellation.
 
     To the extent permitted by the Company Option Plans, the Company Option
Plans will 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. Purchaser shall make available to the
Company all funds required to make the payments to the holders of Company
Options as set forth above.
 
     Compulsory Acquisition. The Tender Agreement provides that 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.
 
     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
Offer Price.
 
     Representations and Warranties. The Tender Agreement contains customary
representations and warranties of the parties thereto. These representations and
warranties expire on the Closing Date.
 
     Conduct of Business Pending the Effective Time. The Company has agreed that
from the date of the Tender Agreement until the Effective Time, the Company
shall, and shall cause its subsidiaries to (except as otherwise required or
contemplated by the Tender Agreement and the schedules thereto or as required by
applicable law): (i) use all commercially reasonable efforts to conduct its
business and the business of its subsidiaries in all material respects only in
the ordinary course of business and consistent with past practice; (ii) not
amend its Articles of Association or Memorandum of Association or other
organizational or governing documents or declare, set aside or pay any dividend
or other distribution or payment in cash, stock or property in respect of its
capital stock or acquire, directly or indirectly, any of its capital stock;
(iii) not issue, grant, sell or pledge or agree or authorize the issuance,
grant, sale or pledge of any shares of, or rights of any kind to acquire any
shares of, its capital stock other than Shares issuable upon the exercise of
stock options outstanding on the date of the Tender Agreement; (iv) not acquire,
sell, transfer, lease or encumber any material assets except in the ordinary
course of business and consistent with past practice; (v) use all
                                       22
<PAGE>   25
 
commercially reasonable efforts to preserve intact its business organizations
and the business organizations of its subsidiaries, and to keep available the
services of its present key officers and employees; provided, however, that the
Company shall not be required to make any payments or enter into or amend any
contractual arrangements or understandings, except in the ordinary course of
business and consistent with past practice and provided further that the
foregoing shall not restrict the Company in any way from terminating the
employment of its employees, other than its present key officers and employees;
(vi) not adopt a plan of complete or partial liquidation or adopt resolutions
providing for the complete or partial liquidation, dissolution, consolidation,
amalgamation, merger, restructuring or recapitalization of the Company or any of
it subsidiaries; (vii) not grant any severance or termination pay (otherwise

directors; (viii) not, except in the ordinary course of business consistent with
past practice or pursuant to obligations imposed by collective bargaining
agreements, increase the compensation payable or to become payable to its
officers or employees, enter into any contract or other binding commitment in
respect of any such increase with any of its directors, officers or other
employees or any director, officer or other employee of its subsidiaries, and

any collective bargaining agreement or Company Plan (as defined in the Tender
Agreement), except as required by applicable law, including any obligation to

payment, direct or indirect, of any material liability before the same becomes
due and payable in accordance with its terms; (x) not take any action, other
than reasonable and usual actions in the ordinary course of business and
consistent with past practice with respect to accounting policies or procedures
(including tax accounting policies and procedures), except as may be required by
the Commission or the Financial Accounting Standards Board; (xi) not make any
material tax election or permit any material insurance policy naming it as a

fees in excess of those disclosed to Purchaser in the Tender Agreement; (xiii)
not amend the Director Releases or incur or pay or agree to pay any amount in

withheld pursuant to applicable tax regulations, pursuant to the Director
Releases; and (xiv) not authorize or enter into an agreement to do any of the
foregoing.
 
     Access; Confidentiality. The Tender Agreement provides that, from the date
of the Tender Agreement until the Closing Date, the Company shall, subject to
certain restrictions, give Purchaser and its authorized representatives access
to its officers or other representatives, properties, books and records, and
shall furnish Purchaser and its authorized representatives with such financial
and operating data and other information concerning the business and properties
of the Company as Purchaser may from time to time reasonably request, subject to
such information being held subject to the provisions of the Confidentiality
Agreement described below under "Confidentiality Agreement."
 
     Non-Solicitation. The Tender Agreement provides that, without the prior
written consent of the other party, neither Purchaser nor the Company, will for
a period of one year from the date of the Tender Agreement, solicit or cause to
be solicited the employment of any person who is employed by the other during
such time, subject to certain limited exceptions set forth in the Tender
Agreement.

agreed to use reasonable efforts to take, or cause to be taken, all actions
necessary, proper or advisable to consummate and make effective the transactions
contemplated by the Tender Agreement as soon as practicable, including the

<PAGE>   26
 
     Acquisition Proposals; Fiduciary Exceptions. The Tender Agreement provides
that, except as set forth in the following paragraph, the Company will not (and
shall not permit any of its subsidiaries to, and shall use its best efforts to
cause its officers, directors and employees and any investment banker, attorney,
accountant, or other agent retained by it or any of its subsidiaries not to)
directly or indirectly (i) solicit, initiate, facilitate or knowingly encourage
(including by way of furnishing information) any inquiry or the making of any
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, or furnish to another person (other than Purchaser or a representative
of Purchaser) any information with respect to its business, properties or assets
for the purpose of facilitating any Company Transaction Proposal. The Company
has also agreed that, except as set forth in the following paragraph, its board
of directors will not change its recommendation of the Offer discussed under the
heading "Company Action; Recommendation of board of directors" above.
 
     The Tender Agreement provides that neither the foregoing provisions or any
other provision in Tender Agreement shall prohibit the Company from (i)
furnishing information pursuant to an appropriate confidentiality letter
concerning the Company and its businesses, properties or assets to a third party
who has made a Superior Proposal (as defined below), (ii) engaging in
discussions or negotiations with a third party who has made a Superior Proposal
or (iii) following receipt of a Superior 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, that such action is necessary in order for the
board of directors of the Company 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 Company Transaction Proposal, then the
Company shall immediately inform Purchaser of the terms and conditions of such
proposal and the identity of the person making it and shall keep Purchaser fully
informed of the status and details of any such Company Transaction Proposal and
of all steps it is taking in response to such Company Transaction Proposal.
"Superior Proposal" is defined to mean a bona fide Company 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.
 
     Break-Up Fee. The Tender Agreement provides that if (i) the Tender
Agreement is terminated by Purchaser or the Company as a result of the Company
withdrawing, withholding or modifying in a manner adverse to Purchaser its
approval of this the Tender Agreement or the Offer, or (ii) (A) prior to the
Closing Date, there is publicly announced by a third 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 to the consummation of the Tender Agreement; 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 the Tender Agreement and before termination of the
Tender Agreement has publicly announced a proposal for Alternative Company
Transaction, in either case prior to twelve months after the date of termination
of the Tender Agreement, then, in any such event (unless the Tender Agreement
has been terminated by the Company as a result of a breach of the agreement by
Purchaser), 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

     The term "Alternative Company Transaction" means 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
(including stock of any subsidiary) constituting 25% or more of the market value
or earning power of the Company on a consolidated basis.
 
     Indemnification. The Tender Agreement provides that, 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 Purchaser will indemnify and
hold harmless each present and former director and officer of the Company and
its subsidiaries against liabilities (including fees and disbursements) incurred
in connection with any claim, action, suit, proceeding or investigation 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 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 of the Tender Agreement, to indemnify such
Person.
 
     Purchaser Benefit Plans. The Tender Agreement provides that, 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") 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. 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. Each
of the employment agreements, the employment security agreements and severance
agreements for the benefit of Company Personnel identified in the Company's
disclosure schedule related to the Tender Agreement shall be continued by the
Company at 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.
 
     Purchaser Stock Options. The Tender Agreement provides that, 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 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.
 
     Post-Closing Operations. In the Tender Agreement, Purchaser expressed its
intent that, following the Closing Date, 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) will remain in Israel.

          (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

     not elected to commence a new Offer pursuant to provision described below
     under "Commencement of a New Offer"; and provided, further that the
     foregoing right to terminate the Tender Agreement shall not be available to
     any party whose misrepresentation in the Tender Agreement or whose failure
     to perform any of its covenants and agreements or to satisfy any obligation
     under the Tender Agreement has been the cause of or resulted in the failure
     of the Closing Date to occur on or before the applicable dates specified
     above;
 
          (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 the Tender Agreement and such judgment, injunction, order
     or decree shall have become final and nonappealable (provided that the
     party seeking to terminate the Tender Agreement pursuant to this provision
     shall have used commercially reasonable efforts to remove such judgment,
     injunction, order or decree) or if any statute, rule, regulation or

     consummation of the Offer shall be in effect;
 
          (d) by the Company, if (i) Purchaser fails to commence the Offer as
     provided in the Tender Agreement other than as a result of any action by
     the Company in violation of the Tender Agreement, (ii) the Offer expires or

     purchase validly tendered Shares in violation of the terms and conditions
     of the Offer or the Tender Agreement;
 
          (e) by Purchaser, if (i) the Offer is not commenced as provided in the
     Tender Agreement directly as a result of actions or inaction by the Company
     in violation of the Tender Agreement, (ii) the Company's board of directors
     shall have withdrawn, withheld or modified in a manner adverse to Purchaser
     its approval of the Tender Agreement or the Offer or (iii) the Offer is
     terminated or expires as a result of the failure of a condition specified
     to the Offer 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 the
     Tender Agreement or the Offer in accordance with the provisions described
     above under "Acquisition Proposals; Fiduciary Exceptions" and paid to
     Purchaser the Break-Up Fee described above under "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.
 
     Fees and Expenses. Whether or not the Offer is consummated, all costs and
expenses incurred in connection with the Tender Agreement and the transactions

counsel, financial advisors and accountants) shall be borne by the party which
incurs such cost or expense.
 
                                       26

     Conditions to the Offer. The Tender Agreement provides that the Offer shall
only be conditioned on satisfaction of the conditions set forth in Section 14
hereof.
 
     Survival. None of the representations, warranties, covenants or agreements
contained in the Tender Agreement or in any certificate or other instrument
delivered pursuant thereto will survive the Closing Date, except for the
covenants and agreements described above under "Indemnification and Insurance,"
"Company Plans," and "Purchaser Stock Options."
 
     Commencement of a New Offer. The Tender Agreement provides that in the
event the original Offer expires as a result of any or all of the conditions to
the Offer set forth in paragraphs (1), (2), (3), (4), (5), (6)(a) and (6)(b) of
in Section 14 hereof not being been fulfilled, Purchaser shall have the right to
commence a new Offer within 10 days of such expiration. Such new Offer shall be
conducted on the same terms as the original Offer, and the terms of the Tender
Agreement shall in all respects apply to such new Offer in the same manner as it
applied to the original Offer except where the context indicates otherwise.
 
SHAREHOLDER AGREEMENTS
 
     Concurrently with execution of the Tender Agreement, Purchaser has also
entered into shareholder agreements with (i) Yossie Hollander and (ii) with Roni
A. Einav, Dalia Prashker and Einav Computer Systems (each a "Principal
Shareholder" and collectively, the "Principal Shareholders"), each dated as of
March 7, 1999 (the "Shareholder Agreements"). Einav Computer Systems is an
Israeli corporation owned by Roni A. Einav and Dalia Prashker. As of the date of
the Shareholder Agreements, Yossie Hollander held an aggregate of 3,741,250
Shares and no Company Options; Einav Computer Systems held an aggregate of
3,741,250 Shares; Roni A. Einav held an aggregate of 23,000 Company Options and
Dalia Prashker held no Company Options. The aggregate number of Shares covered
by the Shareholder Agreements, as of the date thereof, was 7,482,500 Shares, or
61.0% of the issued and outstanding Shares as of such date (in each case
excluding Shares issuable upon exercise of the foregoing Company Options).
 
     The following is a summary of the material terms of such Shareholder
Agreements. This summary is not a complete description of the terms and
conditions thereof and is qualified in its entirety by reference to the full
text thereof, which is incorporated herein by reference and a copy of which has
been filed with the Commission as an exhibit to the Schedule 14D-1. The
Shareholder Agreements may be examined, and copies thereof may be obtained, as
set forth in Section 9 above.
 
     Agreement to Tender Shares. The Shareholder Agreements provide that each
Principal Shareholder will (i) tender all of such Principal Shareholder's
Applicable Shares (as defined below) 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 (as defined below).
 
     As used in the Shareholders Agreements:
 
          "Applicable Shares" means all Shares that are beneficially owned (as
     defined in the Shareholders Agreements) by the Principal Shareholder or
     that become beneficially owned by the Principal Shareholder prior to the
     Termination Date;
 
          "Offer Termination Date" means 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; and
 
          "Termination Date" means the date ending on the first to occur of: (1)
     the Closing Date under the Offer; (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 Section 14 of this Offer to Purchase
     have been satisfied, except for the conditions set forth in paragraphs
     (6)(d)(ii) or (6)(e) of Section 14, and Purchaser elects to terminate the
     Tender Agreement without the purchase of Shares thereunder; provided,
     however, that,
 
                                       27
<PAGE>   30
 
     notwithstanding subparagraphs (2) and (3) above, if after the date of the
     Shareholder Agreements (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
     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 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
     withdraws, withholds or modifies in a manner adverse to Purchaser its
     approval of the Tender Agreement or the Offer pursuant to the applicable
     provisions of the Tender Agreement, 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.
 
     In addition, the Shareholder Agreements provide that in the event that (i)
the 90 % Condition is not satisfied, (ii) Purchaser notifies the Principal
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 the Principal
Shareholder of the Shares underlying such Principal Shareholder's Company
Options, either alone or when aggregated with other Company Options, would cause
the 90% Condition to be satisfied, then such Principal Shareholder hereby agrees
that, at any time prior to the Termination Date, immediately upon the request of
Purchaser, such Principal Shareholder shall exercise all Company Options
beneficially owned by such Principal Shareholder and immediately tender the
Shares received upon such exercise into the Offer (and not withdraw such Shares
so tendered). The Shareholder Agreements provide that Purchaser will advance to
the Principal Shareholders the funds necessary to pay the exercise price of such
Company Options, and the Principal Shareholders shall repay Purchaser the amount
of such advance, without interest, immediately upon receipt of the Offer Price
by such Principal Shareholder for the Shares received upon such exercise. Except
as may be required by the foregoing, the Principal Shareholders have agreed not
to exercise any Company Options owned by them.
 
     Option to Purchase Shares. Pursuant to the Shareholders Agreements, each
Principal Shareholder has granted Purchaser an irrevocable option (the "Purchase
Options") to purchase any or all of such Principal Shareholder's Applicable
Shares at the Offer Price (as such may be increased in connection with the
Offer), subject to the terms of the Shareholder Agreements. The Purchase Options
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 each Purchase Option must be exercised in a
proportionate amount among the Principal Shareholders with the other Purchase
Options.
 
     Voting Matters. The Shareholder Agreements provide that until the
Termination Date, at any meeting of the holders of Shares however called, or in
any other circumstance upon which the vote, consent or other approval of holders
of Shares is sought, the Principal Shareholders shall vote (or cause to be
voted) their issued and outstanding Applicable Shares: (i) against any action or
agreement that would result in a breach in any material respect of any covenant,
representation or warranty or any other material obligation or agreement of
Company under the Tender Agreement or the Shareholder Agreements; (ii) against
the following actions (other than the transactions contemplated by the Tender
Agreement): (A) any Company Transaction Proposal, and (B) to the extent that
such (1) are intended to, or could reasonably be expected to, impede, interfere
with, delay, postpone, or materially adversely affect the Offer, or the
transactions contemplated by the Tender Agreement or the Shareholder Agreements
or (2) are intended to, or could reasonably be expected to, implement or lead to
any Company Transaction Proposal: (x) any change in a majority of the persons
who constitute the board of directors of Company; (y) any change in the
capitalization of Company or any amendment of Company's Memorandum and Articles
of Association (other than as expressly contemplated by the Tender Agreement);
or (z) any other material change in Company's corporate structure or business;
and (iii) for the proposals required under the Tender Agreement to be presented
at the Special Meeting and
 
                                       28
<PAGE>   31
 
any and all other matters contemplated by the Tender Agreement and presented at
the Special Meeting. In addition, each Principal Shareholder has granted to
Purchaser (or its nominees) an irrevocable proxy and attorney-in-fact (with full
power of substitution), until the Termination Date, to vote its Applicable
Shares, or to grant a consent or approval in respect of its Applicable Shares on
any and all matters relating to the Tender Agreement, the Offer or any Company
Transaction Proposal. Each Principal Shareholder has further agreed, until the
Termination Date, not to take any action (including the tender of any Shares)
that could reasonably be expected to, implement or lead to any Company
Transaction Proposal.
 
     Capture Provisions. The Shareholder Agreements provide that, in the event
the Applicable Shares of a Principal 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, such
Principal 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. For the
purposes of the foregoing, "Profit" means an amount equal to the excess, if any,
of (a) the per Share value of all consideration received in connection with an
Alternative Disposition (valued and determined as set forth in the Shareholder
Agreements) over (b) the Offer Price, multiplied by Principal Shareholder's
Applicable Shares sold, transferred, exchanged, canceled or disposed of in such
Alternative Disposition.
 
     Release Provisions. The Shareholder Agreements include an unconditional
release by each Principal Shareholder of all claims, demands, liabilities,
responsibilities, disputes, causes of action and similar matters of such
Principal Shareholder against the Company and its subsidiaries, subject to
certain exceptions relating to breaches of the Shareholder Agreements or the
Tender Agreement.
 
     Escrow Agreements. In connection with the execution by Purchaser and the
Principal Shareholders of the Shareholder Agreements, each Principal Shareholder
has executed an Escrow Agreement pursuant to which such Principal Shareholder
has agreed that the Applicable Shares owned by such Principal Shareholder (with
certain exceptions in the case of Mr. Hollander) and any Shares issuable to such
Principal Shareholder upon exercise of Company Options shall be placed with an
escrow agent within five business days after the date of the Shareholder
Agreements, to be disbursed in accordance with the provisions of the Shareholder
Agreement.
 
DIRECTOR RELEASES
 
     To resolve certain claims by Yehuda Kahane, Nahum Rozman and Eli Talmor,
each of whom is a director of the Company, that the Company owed such directors
compensation relating to past services, in connection with the execution of the
Tender Agreement, Purchaser required the Company to obtain general releases
(each a "Director Release" and collectively, the "Director Releases") from each
such individual. Pursuant to the Director Releases, the Company has agreed to
make a cash payment, immediately prior to the Closing Date, in an aggregate
amount of $7,500,000 (plus value added tax as prescribed by law against a duly
issued value added tax invoice) less any amounts required to be withheld under
applicable tax law, in full satisfaction of the release by all of such directors
of any and all claims, demands, liabilities, responsibilities, disputes, causes
of action and similar matters (whether relating to compensation or otherwise)
held by such directors against the Company or its subsidiaries. The $7,500,000
payment will be allocated among the directors as they determine.
 
     The foregoing is a summary of the material terms of the Director Releases.
This summary is not a complete description of the terms and conditions thereof
and is qualified in its entirety by reference to the full text thereof, which is
incorporated herein by reference and a form of which has been filed with the
Commission as an exhibit to the Schedule 14D-1. The Director Releases may be
examined, and copies thereof may be obtained, as set forth in Section 9 above.
 
                                       29
<PAGE>   32
 
CONFIDENTIALITY AGREEMENT
 
     The Confidentiality Agreement dated January 6, 1999 between the Company and
the Purchaser (the "Confidentiality Agreement") contains customary provisions
pursuant to which, among other things, Purchaser has agreed, subject to certain
exceptions, to keep confidential for a period of two years all financial,
technical, commercial or other information concerning the Company which is
furnished to Purchaser by or on behalf of the Company (the "Confidential
Information"), and to use the Confidential Information solely for the purpose of
evaluating a possible business transaction involving the Company and Purchaser.
 
     Pursuant to the Confidentiality Agreement, Purchaser has agreed that the
Confidential Information shall not be used for competitive purposes and that,
prior to the earlier of 18 months from the date of the Confidentiality Agreement
and the consummation of a business transaction between the Company and
Purchaser, Purchaser will not knowingly solicit any employee of the Company for
employment (with certain exceptions). The Confidentiality Agreement also
provides that the parties will not disclose to any person that any negotiations
have occurred concerning a possible transaction.
 
AGREEMENTS RELATING TO BOOLE & BABBAGE DISTRIBUTION AGREEMENT
 
     As an inducement to Purchaser entering into the Tender Agreement and
consummating the transactions contemplated thereby, concurrently with the
execution and deliver of the Tender Agreement, the Company agreed to amend the
Distribution Agreement between the Company and BBE, its European distributor.
Purchaser is currently in the process of acquiring Boole, the parent company of
BBE. The Amendment excludes the Offer from the provisions of the Distribution
Agreement which provide that a change of control of the Company would result in
the right by BBE to terminate the Distribution Agreement and receive a
termination payment from the Company. In addition, the Company executed a side
letter (the "Side Letter") which provides that the Company will not exercise its
right to terminate the Distribution Agreement by reason of Purchaser's
acquisition of Boole until April 10, 1999. The Side Letter further provides
that, upon completion of the acquisition of Boole by Purchaser, the Company and
BBE will enter into a fourth amendment of the Distribution Agreement, which will
provide for the extension of the period during which the Company has a right to
terminate the Distribution Agreement as a result of Purchaser's purchase of
Boole until December 31, 1999, provided, that the Company will not give notice
of its intent to terminate the Distribution Agreement in connection with
Purchaser's purchase of Boole until the earlier of the day first succeeding the
termination of the Offer or July 12, 1999 and that such termination notice will
become effective within 60 days as of the receipt thereof by BBE.
 
EMPLOYMENT AGREEMENTS
 
     Purchaser intends to maintain and extend existing employment agreements
with Mr. Barnea and other key management employees who are not directors of the
Company. In that connection, Purchaser is discussing amending certain provisions
of such agreements, including termination notice requirements, grants of stock
options by Purchaser and non-solicitation restrictions. It is anticipated that a
large portion of the stock options to be issued by Purchaser pursuant to the
Tender Agreement will be issued to key employees in connection with such amended
employment agreements. As of the date hereof, Purchaser and such employees have
not entered into definitive amendments to existing employment agreements.
 
13. DIVIDENDS AND DISTRIBUTIONS
 
     The Tender Agreement provides that during the period from the date of the
Tender Agreement and continuing until the Closing Date, except as otherwise
required or contemplated by the Tender Agreement or as required by applicable
law, the Company shall, and shall cause its subsidiaries, to: (i) not amend its
Articles of Association or Memorandum of Association or other organizational or
governing documents or declare, set aside or pay any dividend or other
distribution or payment in cash, stock or property in respect of its capital
stock or acquire, directly or indirectly, any of its capital stock, (ii) not
issue, grant, sell or pledge or agree or authorize the issuance, grant, sale, or
pledge of any shares of, or rights of any kind to acquire shares of, its capital
stock other than Shares issuable upon exercise of stock options outstanding on
the date of the
 
                                       30
<PAGE>   33
 
Tender Agreement or issuable upon the exercise of convertibility features in its
securities outstanding on the date of the Tender Agreement, and (iii) not
authorize or enter into any agreement to do any of the foregoing.
 
14. CERTAIN CONDITIONS OF THE OFFER
 
     Purchaser shall not be required to accept for payment, purchase or pay for
any Shares tendered and Purchaser may terminate or, subject to the terms and
conditions of the Tender Agreement, amend the Offer as to any Shares not then

     provisions; provided, however, that the foregoing shall not require the
     Company to have obtained such an agreement from any holder of a Company

     subsidiary of the Company) who is not employed by the Company or its
     subsidiaries at the Closing Date;
 
          (5) the Director Releases shall not have become effective in

        court or governmental, administrative or regulatory authority or agency,
        located or having jurisdiction within the United States or State of
        Israel, or any other action taken, proposed or threatened, or statute,
        rule, regulation, legislation, interpretation, judgment or order
        proposed, sought, enacted, entered, enforced, promulgated, amended,
        issued or deemed applicable to Purchaser, the Company or any subsidiary
        or affiliate of Purchaser or the Company or the Offer, by 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 or
        otherwise restraining or prohibiting the Offer or the acquisition by
        Purchaser of any Shares or the Compulsory Acquisition; (ii) prohibiting
        or materially limiting the ownership or operation by Purchaser or its
        affiliates of any material portion of the business or assets of the
        Company or compelling Purchaser to dispose of or hold separate all or
        any material portion of the business or assets of the Company, in each
        case as a result of the transactions contemplated by the Tender
        Agreement; (iii) imposing material limitations on the ability of
        Purchaser or any of its affiliates to exercise full rights of ownership
        of the Shares, including, without limitation, the right to vote any
        Shares purchased by them on all matters properly presented to the
        shareholders of the Company; or (iv) preventing Purchaser or any of its
        affiliates from acquiring, or to require divestiture by Purchaser or any
        of its affiliates of, any Shares in the Offer; or
 
                                       31
<PAGE>   34
 
             (b) there shall have occurred (i) any general suspension of, or
        limitation on prices for, trading in securities on any national
        securities exchange or in the over-the-counter market in the United
        States, (ii) the declaration of any banking moratorium or any suspension
        of payments in respect of banks or any limitation (whether or not
        mandatory) on the extension of credit by lending institutions in the
        United States, or (iii) the commencement of a war, material armed
        hostilities or any other material international or national calamity
        involving the United States or the State of Israel and, in the case of
        armed hostilities involving Israel, having, or which could reasonably be
        expected to have, a substantial continuing general effect on business
        and financial conditions in Israel; or
 
             (c) any Person, entity or "group" (as such term is used in Section
        13(d)(3) of the Exchange Act) other than Purchaser or any of its
        affiliates shall have become the beneficial owner (as that term is used
        in Rule 13d-3 under the Exchange Act) of more than 50% of the
        outstanding Shares; or
 
             (d) (i) the Company shall have breached or failed to comply in any
        material respect with any of its obligations under the Tender Agreement
        (which breach, if curable, has not been cured within thirty (30) days
        following receipt of written notice thereof by Purchaser specifying in
        reasonable detail the basis of such alleged breach), (ii) or any
        representation or warranty of the Company contained in the Tender
        Agreement shall not have been true and correct as of such time, except
        (x) for changes specifically permitted or contemplated by the Tender
        Agreement; or (y) where the failure of representations and warranties
        (without giving effect to any limitation based on materiality or
        Material Adverse Effect or words of similar effect set forth therein) to
        be true and correct would not, in the aggregate, reasonably be expected
        to have a Material Adverse Effect; or
 
             (e) there shall have occurred a Material Adverse Effect, other than
        as a result of the transactions specifically contemplated by the Tender
        Agreement; or
 
             (f) the Tender Agreement shall have been terminated pursuant 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.
 
15. CERTAIN LEGAL MATTERS
 
     Except as described in this Section 15, based on a review of publicly
available filings made by the Company with the Commission and other publicly
available information concerning the Company, but without any independent
investigation thereof, Purchaser is not aware of any license or regulatory
permit that appears to be material to the business of the Company and its
subsidiaries, taken as a whole, that might be adversely affected by Purchaser's
acquisition of Shares as contemplated herein or of any approval or other action
by any Governmental Authority that would be required for the acquisition or
ownership of Shares by Purchaser as contemplated herein. Should any such
approval or other action be required, Purchaser currently contemplates that such
approval or other action will be sought. While, except as otherwise expressly
described in this Section 15, Purchaser does not presently intend to delay the
acceptance for payment of or payment for Shares tendered pursuant to the Offer
pending the outcome of any such matter, there can be no assurance that any such
approval or other action, if needed, would be obtained or would be obtained
without substantial conditions or that failure to obtain any such approval or
other action might not result in consequences adverse to the Company's business
or that certain parts of the Company's business might not have to be disposed of
if such approvals were not obtained or such other actions were not taken or in
order to obtain any such approval
 
                                       32
<PAGE>   35
 
or other action. If certain types of adverse action are taken with respect to
the matters discussed below, Purchaser could decline to accept for payment or
pay for any Shares tendered. See Section 14 above for certain conditions to the
Offer.
 
     Antitrust. Under the applicable provisions of the Hart-Scott-Rodino
Antitrust Improvement Act of 1976, as amended, (the "HSR Act"), and the rules
that have been promulgated thereunder by the Federal Trade Commission (the
"FTC"), the purchase of Shares pursuant to the Offer may be consummated
following the expiration of a 15-calendar-day waiting period following the
filing by Purchaser of a Pre-Merger Notification and Report Form with respect to
the Offer, unless Purchaser receives a request for additional information or
documentary material from the Antitrust Division of the United States Department
of Justice (the "Antitrust Division") or the FTC or unless early termination of
the waiting period is granted. Purchaser expects to file a Pre-Merger
Notification and Report Form with respect to the Offer as soon as practicable
following commencement of the Offer. If, within the initial 15-day waiting
period, either the Antitrust Division or the FTC requests additional information
or documentary material from Purchaser concerning the Offer, the waiting period
will be extended and will expire on the tenth calendar day after the date of
substantial compliance by Purchaser with such request. Only one extension of the
waiting period pursuant to a request for additional information is authorized by
the HSR Act. Thereafter, such waiting period may be extended only by court order
or with the consent of Purchaser. In practice, complying with a request for
additional information or documentary material can take a significant amount of
time. In addition, if the Antitrust Division or the FTC raises substantive
issues in connection with a proposed transaction, the parties frequently engage
in negotiations with the relevant governmental agency concerning possible means
of addressing those issues and may agree to delay consummation of the
transaction while such negotiations continue. The Tender Agreement generally
provides that Purchaser will not be required to accept for payment, purchase or
pay for any Shares tendered until the expiration of any applicable waiting
period under the HSR Act.
 
     The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as Purchaser's proposed acquisition of
the Company. At any time before or after Purchaser's purchase of Shares pursuant
to the Offer, the Antitrust Division or the FTC could take such action under the
antitrust laws as it deems necessary or desirable in the public interest,
including seeking to enjoin the purchase of Shares pursuant to the Offer or
seeking the divestiture of Shares acquired by Purchaser or the divestiture of
substantial assets of Purchaser or its subsidiaries, or the Company or its
subsidiaries. Private parties may also bring legal action under certain
circumstances. There can be no assurance that a challenge to the Offer on
antitrust grounds will not be made or, if such a challenge is made, of the
result thereof.
 
     Federal Reserve Board Regulations. Regulations G, U and X (the "Margin
Regulations") of the Federal Reserve Board restrict the extension or maintenance
of credit for the purpose of buying or carrying margin stock (which restriction
would include the Shares) if the credit is secured directly or indirectly by
margin stock. Such secured credit may not be directly secured by margin stock
and, in addition, such secured credit may not be indirectly secured by margin
stock having a value in an amount that exceeds the maximum loan value of all the
direct and indirect collateral securing the credit, including margin stock and
other collateral.
 
     As described in Section 10 of this Offer to Purchase, the financing of the
Offer will not be directly or indirectly secured by the Shares or other
securities which constitute margin stock. Accordingly, all financing for the
Offer will be in full compliance with the Margin Regulations.
 
     Israeli Regulatory Approvals. The closing of the Offer, and the acceptance
of Shares by the Purchaser under the Offer, is subject to (i) the approval of
the Investment Center of the Ministry of Trade and Industry of the State of
Israel (the "Investment Center") and (ii) the approval of the Office of the
Chief Scientist of the Ministry of Trade and Industry of the State of Israel
(the "OCS"). The closing of the Offer may require the approval of the Antitrust
Director of the State of Israel (the "Antitrust Director") unless an exemption
is obtained.
 
     The approval of the Investment Center is required as a condition of the
"approved enterprise" programs in which the Company participates and pursuant to
which the Company receives certain tax benefits.
 
                                       33
<PAGE>   36
 
     The approval of the OCS is required as a condition of certain
royalty-bearing grants which the Company has received from the OCS in order to
fund certain research and development programs.
 
     The Antitrust Director oversees antitrust enforcement in Israel. It is
unclear whether Israeli antitrust laws apply to the Offer. If the acquisition of
the Shares by the Purchaser pursuant to the Offer is deemed to be a "merger"
within the meaning of the Restrictive Trade Practices Law, 5748-1988, of the
State of Israel, then both the Purchaser and the Company will be required to
make filings with the Antitrust Director regarding sales activity in Israel, and
obtain the approval of the Antitrust Director to the transaction. The Antitrust
Director is required to respond to all such filings within 30 days.
 
16. FEES AND EXPENSES
 
     Purchaser has retained Goldman, Sachs & Co. to act as the Dealer Managers
in connection with the Offer and to provide certain financial advisory services.
Goldman, Sachs & Co. will receive reasonable and customary fees, will be
reimbursed for certain reasonable out-of-pocket expenses and will be indemnified
against certain liabilities and expenses in connection therewith, including
certain liabilities under the federal securities laws.
 
     Purchaser has retained MacKenzie Partners, Inc. to act as the Information
Agent and BankBoston, N.A. to act as the Depositary in connection with the
Offer. The Information Agent and the Depositary will receive reasonable and
customary compensation for their services, will be reimbursed for certain
reasonable out-of-pocket expenses and will be indemnified against certain
liabilities and expenses in connection therewith, including certain liabilities
under the federal securities laws.
 
     Except as set forth above, Purchaser will not pay any fees or commissions
to any broker or dealer or other person for soliciting tenders of Shares
pursuant to the Offer. Brokers, dealers, commercial banks and trust companies
will be reimbursed by Purchaser for customary mailing and handling expenses
incurred by them in forwarding the offering materials to their customers.
 
17. MISCELLANEOUS
 
     The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares residing in any jurisdiction in which the making of
the Offer or the acceptance thereof would not be in compliance with the
securities, blue sky or other laws of such jurisdiction. However, the Purchaser
may, in its discretion, take such action as it may deem necessary to make the
Offer in any jurisdiction and extend the Offer to holders of Shares in such
jurisdiction. In those jurisdictions where securities, blue sky or other laws
require the Offer to be made by a licensed broker or dealer, the Offer shall be
deemed to be made on behalf of the Purchaser by the Dealer Managers or one or
more registered brokers or dealers that are licensed under the laws of such
jurisdictions.
 
     Purchaser has filed with the Commission the Schedule 14D-1 pursuant to Rule
14d-1 under the Exchange Act containing certain additional information with
respect to the Offer. Such Schedule and any amendments thereto, including
exhibits, may be examined and copies may be obtained from the principal office
of the Commission in the manner set forth in Section 9 above (except that they
will not be available at the regional offices of the Commission).
 
     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF PURCHASER NOT CONTAINED IN THIS OFFER TO PURCHASE OR
IN THE LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, SUCH INFORMATION OR
REPRESENTATIONS MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

Ladies and Gentlemen:
 
     The undersigned hereby tenders to BMC Software, Inc., a Delaware
corporation ("Purchaser"), the above-described ordinary shares, NIS 0.01 par
value per share (the "Shares"), of New Dimension Software Ltd., an Israeli
corporation (the "Company"), at a purchase price of $52.50 per Share, net to the
seller in cash, upon the terms and subject to the conditions set forth in the
Purchaser's Offer to Purchase, dated March 11, 1999 (the "Offer to Purchase"),
receipt of which is hereby acknowledged, and in this Letter of Transmittal
(which, together with any amendments or supplements hereto or thereto,
collectively constitute the "Offer"). The undersigned understands that the
Purchaser reserves the right to assign, in its sole discretion, to any
newly-formed direct wholly owned subsidiary of Purchaser, the right to purchase
Shares tendered pursuant to the Offer.
 
     Accordingly, the undersigned hereby deposits with you the above-described
certificates representing the Shares. Subject to, and effective upon, acceptance
for payment of the Shares validly tendered herewith in accordance with the terms
and subject to the conditions of the Offer, the undersigned hereby sells,
assigns and transfers to, or upon the order of, Purchaser all right, title and
interest in and to all of the Shares that are being tendered hereby that are
purchased pursuant to the Offer and any and all other distributions, rights,
other Shares or other securities issued or issuable in respect of such Shares on
or after March 11, 1999 (a "Distribution") and hereby irrevocably constitutes
and appoints the Depositary as the true and lawful agent and attorney-in-fact of
the undersigned with respect to such Shares (and any Distributions), with full
power of substitution (such power of attorney being deemed to be an irrevocable
power coupled with an interest), to (i) deliver certificates (the
"Certificates") evidencing such Shares (and any Distributions), or transfer
ownership of such Shares (and any Distributions) on the account books maintained
by the Book-Entry Transfer Facility together, in any such case, with all
accompanying evidences of transfer and authenticity to, or upon the order of,
Purchaser upon receipt by the Depositary, as the undersigned's agent, of the
purchase price with respect to such Shares, (ii) present such Shares (and any
Distributions) for transfer on the books of the Company and (iii) receive all
benefits and otherwise exercise all rights of beneficial ownership of such
Shares (and any Distributions), all in accordance with the terms and subject to
the Offer.
 
     The undersigned hereby irrevocably appoints each designee of Purchaser as
the attorney-in-fact and proxy of the undersigned, each with full power of
substitution, to the full extent of the undersigned's rights with respect to all
Shares (and any Distributions) tendered hereby, including, without limitation,
the right to vote such Shares (and any Distributions) in such manner as each
such attorney and proxy or his substitute shall, in his sole discretion, deem
proper. All such powers of attorney and proxies shall be considered coupled with
an interest in the Shares tendered herewith and therefore be irrevocable. Such
appointment will be effective when, and only to the extent that, Purchaser
accepts such Shares for payment pursuant to the Offer. Upon such acceptance for
payment, all prior powers of attorney and proxies given by the undersigned with
respect to such Shares (and any Distributions) will be revoked, without further
action, and no subsequent powers of attorneys and proxies may be given by the
undersigned with respect thereto (and, if given, will be deemed ineffective).
The designees of Purchaser will, with respect to the Shares (and any
Distributions) for which such appointment is effective, be empowered to exercise
all voting and other rights of the undersigned with respect to such Shares (and
any Distributions) as they in their sole discretion may deem proper, including,
without limitation, in respect of any general meeting of the Shareholders, or
any adjournment or postponement thereof, in connection with any, action by
written consent in lieu of a meeting or otherwise. The undersigned acknowledges
that Purchaser reserves the absolute right to require that, in order for Shares
to be deemed validly tendered, immediately upon the acceptance for payment of
such Shares, Purchaser or its designees must be able to exercise full voting
rights with respect to such Shares (and any Distributions), including, without
limitation, the right to vote at any meeting of Shareholders then scheduled.
 
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Shares (and
any Distributions) tendered hereby and that when such Shares (and any
Distributions) are accepted for payment and paid for by Purchaser, Purchaser
will acquire good, marketable and unencumbered title thereto, free and clear of
all liens, restrictions, charges and encumbrances, and that the Shares (and any
Distributions) tendered hereby will not be subject to any adverse claim. The
undersigned, upon request, will execute and deliver any additional documents
deemed by the Depositary or Purchaser to be necessary or desirable to complete
the sale, assignment and transfer of Shares (and any Distributions) tendered
hereby. In addition, the undersigned shall
 
                                        5
<PAGE>   6
 
promptly remit and transfer to the Depositary for the account of Purchaser any
and all Distributions issued to the undersigned on or after March 11, 1999 in
respect of the Shares tendered hereby, accompanied by appropriate documentation
of transfer, and pending such remittance and transfer or appropriate assurance
thereof, Purchaser shall be entitled to all rights and privileges as owner of
any such Distributions and may withhold the entire purchase price or deduct from
the purchase price the amount of value thereof, as determined by Purchaser in
its sole discretion.
 
     All authority conferred or agreed to be conferred in this Letter of
Transmittal shall be binding upon the successors, assigns, heirs, executors,
administrators and legal representatives of the undersigned and shall not be
affected by, and shall survive, the death or incapacity of the undersigned.
Except as stated in the Offer to Purchase, this tender is irrevocable.
 
     The undersigned understands that the valid tender of Shares pursuant to any
one of the procedures described in "Procedure for Tendering Shares" in the Offer
to Purchase and in the instructions hereto will constitute a binding agreement
between the undersigned and Purchaser with respect to such Shares upon the terms
and subject to the conditions of the Offer. The undersigned recognizes that,
under certain circumstances set forth in the Offer to Purchase, Purchaser may
not be required to accept for payment any of the Shares tendered hereby.
Purchaser's acceptance for payment of Shares tendered pursuant to the Offer will
constitute a binding agreement between the undersigned and Purchaser upon the
terms and subject to the conditions of the Offer.
 
     Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the check for the purchase price and/or return any Certificates
evidencing Shares not tendered or not accepted for payment in the name(s) of the
registered holder(s) appearing under "Description of Shares Tendered."
Similarly, unless otherwise indicated under "Special Delivery Instructions,"
please mail the check for the purchase price and/or return any Certificates
evidencing Shares not tendered or not accepted for payment (and accompanying
documents, as appropriate) to the address(es) of the registered holder(s)
appearing under "Description of Shares Tendered." In the event that both the
"Special Payment Instructions" and the "Special Delivery Instructions" are
completed, please issue the check for the purchase price and/or return any such
Certificates evidencing Shares not tendered or not accepted for payment (and
accompanying documents, as appropriate) to, the person(s) so indicated. Unless
otherwise indicated herein under "Special Payment Instructions," in the case of
a book-entry delivery of Shares, please credit the account maintained at the
Book-Entry Transfer Facility indicated above with respect to any Shares not
accepted for payment. The undersigned recognizes that Purchaser has no
obligation pursuant to the "Special Payment Instructions" to transfer any Shares
from the name of the registered holder thereof if Purchaser does not accept for
payment any of the Shares tendered hereby.

     (e) If this Letter of Transmittal is signed by the registered holder(s) of
the Shares listed and transmitted hereby, no endorsements of Certificates or
separate instruments of transfer are required. If, however, payment is to be

sale of Shares to it or its order pursuant to the Offer. If, however, payment of
the purchase price is to be made to, or (in the circumstances permitted hereby)
if Certificates for Shares not tendered or not purchased are to be registered in
the name of, any person other than the registered holder(s), or if tendered
Certificates are registered in the name of any person other than the person(s)
signing this Letter of Transmittal, the amount of any transfer taxes (whether
imposed on the registered holder(s) or such person) payable on account of the
transfer to such person will be deducted from the purchase price unless
satisfactory evidence of the payment of such taxes or exemption therefrom is
submitted.
 
     Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Certificate(s) listed in this Letter of
Transmittal.
 
     7. Special Payment and Delivery Instructions. If a check and/or
Certificates for unpurchased Shares are to be issued in the name of a person
other than the signer of this Letter of Transmittal or if a check is to be sent

obligated) to waive or to amend any of the conditions of the Offer or any defect
or irregularity in any tender with respect to Shares of any particular
Shareholder, whether or not similar defects or irregularities are waived in the
case of other Shareholders. No tender of Shares will be deemed to have been
validly made until all defects and irregularities have been cured or waived.
Purchaser's interpretation of the terms and conditions of the Offer (including
this Letter of Transmittal and the instructions hereto) will be final and
binding on all parties. None of Purchaser, the Dealer Managers, the Depositary,
the Information Agent or any other person will be under any duty to give
notification of any defects or irregularities in tenders or incur any liability
for failure to give any such notification.
 
     9. Requests for Assistance or Additional Copies. Questions and requests for

their respective addresses or telephone numbers set forth below and requests for
additional copies of the Offer to Purchase, this Letter of Transmittal and the

of the Offer may be waived by the Purchaser, in whole or in part, at any time or

     11. Backup Withholding Tax. Except in the case of foreign persons, each
tendering Shareholder is required to provide the Depositary with a correct
Taxpayer Identification Number ("TIN") on Substitute Form W-9, which is provided
under "Important Tax Information" below, and to certify that such Shareholder is
not subject to backup withholding. Failure to provide the information on the
Substitute Form W-9 may subject the tendering Shareholder to 31% federal income
tax backup withholding on the payment of the purchase price for the Shares. The
tendering Shareholder should indicate in the box in Part I of the Substitute
Form W-9 if such Shareholder has not been issued a TIN and has applied for a TIN
or intends to apply for a TIN in the near future. If the Shareholder has
indicated in the box in Part I that a TIN has been applied for and the
Depositary is not provided with a TIN by the time of payment, the Depositary
will withhold 31% of all payments of the purchase price, if any, made thereafter
pursuant to the Offer until a TIN is provided to the Depositary. A tendering
Shareholder who is a foreign person (i.e., who is not a citizen or resident of
the United States) should provide the Depositary with a completed Form W-8.
Please contact the Depositary, if necessary, in order to obtain a copy of Form
W-8.
 
     12. Lost or Destroyed Certificates. If any Certificate(s) representing
Shares has been lost or destroyed, the holders should promptly notify the
Depositary, BankBoston, N.A., at the address or facsimile number set forth
herein. The holders will then be instructed as to the procedure to be followed
in order to replace the Certificate(s). This Letter of Transmittal and related
documents cannot be processed until the procedures for replacing lost or
destroyed Certificates have been followed.
 
IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE THEREOF), PROPERLY
COMPLETED AND DULY EXECUTED, MUST BE RECEIVED BY THE DEPOSITARY (TOGETHER WITH
CERTIFICATES OR A BOOK-ENTRY CONFIRMATION FOR SHARES AND ALL OTHER REQUIRED
DOCUMENTS AND/OR SIGNATURES), OR A NOTICE OF GUARANTEED DELIVERY MUST BE
RECEIVED BY THE DEPOSITARY, PRIOR TO THE EXPIRATION DATE (AS DEFINED IN THE
OFFER TO PURCHASE).

                           IMPORTANT TAX INFORMATION
 
     Under federal income tax law, a Shareholder whose tendered Shares are
accepted for payment is required to provide the Depositary (as payor) with such
Shareholder's correct TIN on Substitute Form W-9 below. If such Shareholder is
an individual, the TIN is such individual's social security number. If the
tendering Shareholder has not been issued a TIN and has applied for a number or
intends to apply for a number in the near future, such Shareholder should so
indicate on the Substitute Form W-9. If the Depositary is not provided with the
correct TIN, the Shareholder may be subject to a $50 penalty imposed by the
Internal Revenue Service (the "IRS"). In addition, payments that are made to
such Shareholders with respect to Shares purchased pursuant to the Offer may be
subject to backup federal income tax withholding.
 
     Certain Shareholders are not subject to these backup withholding and
reporting requirements. In order for a foreign person to qualify as an exempt
recipient, such Shareholder generally must submit an I.R.S. Form W-8. An I.R.S.
Form W-8 can be obtained from the Depositary. See the enclosed Guidelines or
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions. Other exempt recipients should complete Form W-9 in
order to avoid the possible imposition of backup withholding.
 
     If backup withholding applies, the Depositary is required to withhold 31%
of any payments made to the Shareholder. Backup withholding is not an additional
tax. Rather, the tax liability of persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in an overpayment
of taxes, a refund may be obtained from the IRS.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
     To prevent backup federal income tax withholding with respect to payment of
the purchase price for Shares purchased pursuant to the Offer, generally a
Shareholder must provide the Depositary with his correct TIN by completing the
Substitute Form W-9 below, certifying that the TIN provided on Substitute Form
W-9 is correct (or that such Shareholder is awaiting a TIN) and that (i) such
Shareholder is exempt from backup withholding or (ii) such Shareholder has not
been notified by the IRS that such Shareholder is subject to backup withholding
as a result of failure to report all interest or dividends or (iii) the IRS has
notified the Shareholder that such Shareholder is no longer subject to backup
withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
     The Shareholder is required to give the Depositary the social security
number or employer identification number of the record holder of the Shares
tendered hereby. If the Shares are registered in more than one name or are not
in the name of the actual owner, consult the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional guidance on which number to report.
 
     NOTE: FAILURE TO COMPLETE AND RETURN THIS SUBSTITUTE FORM W-9 MAY RESULT IN
     BACKUP WITHHOLDING OF 31% OF ANY PAYMENTS MADE TO YOU PURSUANT TO THE
     OFFER. PLEASE REVIEW THE ENCLOSED GUIDELINES FOR CERTIFICATION OF TAXPAYER
     IDENTIFICATION NUMBER ON SUBSTITUTE FORM W-9 FOR ADDITIONAL INSTRUCTIONS.

payee who does not furnish a taxpayer identification number to a payer. Certain
penalties may also apply.

     (1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER -- If you
fail to furnish your taxpayer identification number to a payer, you are subject
to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.
 
     (2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS -- If you fail
to include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
under-payment attributable to that failure unless there is a clear and
convincing evidence to the contrary.
 
     (3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING -- If
you make a false statement with no reasonable basis which results in no
imposition of backup withholding, you are subject to a penalty of $500.
 
     (4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION -- Falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment. FOR ADDITIONAL INFORMATION CONTACT YOUR TAX
CONSULTANT OR THE INTERNAL REVENUE SERVICE.

GENERAL INSTRUCTIONS
(Section references are to the Internal Revenue Code unless otherwise noted.)
 
PURPOSE
Use Form W-8 or a substitute form containing a substantially similar statement
to tell the payer, mortgage interest recipient, middleman, broker, or barter
exchange that you are a nonresident alien individual, foreign entity, or exempt
foreign person not subject to certain U.S. information return reporting or
backup withholding rules.
 
CAUTION: Form W-8 does not exempt the payee from the 30% (or lower treaty)
nonresident withholding rates.
 
NONRESIDENT ALIEN INDIVIDUAL
For income tax purposes, "nonresident alien individual" means an individual who
is neither a U.S. citizen nor resident. Generally, an alien is considered to be
a U.S. resident if:
 
- - The individual was a lawful permanent resident of the United States at any
time during the calendar year, that is, the alien held an immigrant visa (a
"green card"), or
 
- - The individual was physically present in the United States on:
 
   (1) at least 31 days during the calendar year, and
 
   (2) 183 days or more during the current year and the 2 preceding calendar
years (counting all the days of physical presence in the current year, one-
third the number of days of presence in the first preceding year, and only
one-sixth of the number of days in the second preceding year).
 
   See Pub. 519, U.S. Tax Guide for Aliens, for more information on resident and
nonresident alien status.
 
NOTE: If you are a nonresident alien individual married to a U.S. citizen or
resident and have made an election under section 6013(g) or (h), you are treated
as a U.S. resident and may not use Form W-8.
 
EXEMPT FOREIGN PERSON
For purposes of this form, you are an "exempt foreign person" for a calendar
year in which:
 
   1. You are a nonresident alien individual or a foreign corporation,
partnership, estate, or trust,
 
   2. You are an individual who has not been, and plans not to be, present in
the United States for a total of 183 days or more during the calendar year, and
 
   3. You are neither engaged, nor plan to be engaged during the year, in a U.S.
trade or business that has effectively connected gains from transactions with a
broker or barter exchange.
 
   If you do not meet the requirements of 2 or 3 above, you may instead certify
on Form 1001, Ownership, Exemption, or Reduced Rate Certificate, that your
country has a tax treaty with the United States that exempts your transactions
from U.S. tax.
 
FILING INSTRUCTIONS
 
WHEN TO FILE.-- File Form W-8 or substitute form before a payment is made.
Otherwise, the payer may have to withhold and send part of the payment to the
Internal Revenue Service (see Backup Withholding below). This certificate
generally remains in effect for three calendar years. However, the payer may
require you to file a new certificate each time a payment is made to you.
 
WHERE TO FILE.-- File this form with the payer of the qualifying income who is
the withholding agent (see Withholding Agent on page 2). Keep a copy for your
own records.
 
BACKUP WITHHOLDING
A U.S. taxpayer identification number or Form W-8 or substitute from must be
given to the payers of certain income. If a taxpayer identification number or
Form W-8 or substitute form is not provided or the wrong taxpayer identification
number is provided, these payers may have to withhold 20% of each payment or
transaction. This is called backup withholding.
 
NOTE: On January 1, 1993, the backup withholding rate increases from 20% to 31%.
 
   Reportable payments subject to backup withholding rules are:
 
- - Interest payments under section 6049(a).
 
- - Dividend payments under sections 6042(a) and 6044.
 
- - Other payments (i.e., royalties and payments from brokers and barter
exchanges) under sections 6041, 6041A(a), 6045, 6050A, and 6050N.
 
   If backup withholding occurs, an exempt foreign person who is a nonresident
alien individual may get a refund by filing Form 1040NR U.S. Nonresident Alien
Income Tax Return, with the Internal Revenue
 
                                                                     (Continued)

U.S. TAXPAYER IDENTIFICATION NUMBER
The Internal Revenue law requires that certain income be reported to the
Internal Revenue Service using a U.S. taxpayer identification number (TIN). This
number can be a social security number assigned to individuals by the Social
Security Administration or an employer identification number assigned to
businesses and other entities by the Internal Revenue Service.
 
    Payments to account holders who are foreign persons (nonresident alien
individuals, foreign corporations, partnerships, estates, or trusts) generally
are not subject to U.S. reporting requirements. Also, foreign persons are not
generally required to have a TIN, nor are they subject to any backup withholding
because they do not furnish a TIN to a payer or broker.
 
    However, foreign persons with income effectively connected with a trade or
business in the United States (income subject to regular (graduated) income
tax), must have a TIN. To apply for a TIN, use Form SS-4, Application for
Employer Identification Number, available from local Internal Revenue Service
offices, or Form SS-5, Application for a Social Security Card, available from
local Social Security Administration offices.
 
SPECIAL RULES
 
MORTGAGE INTEREST. -- For purposes of the reporting rules, mortgage interest is
interest paid on a mortgage to a person engaged in a trade or business
originating mortgages in the course of that trade or business. A mortgage
interest recipient is one who receives interest on a mortgage that was acquired
in the course of a trade or business.
 
    Mortgage interest is not subject to backup withholding rules, but is subject
to reporting requirements under section 6050H. Generally, however, the reporting
requirements do not apply if the payer of record is a nonresident alien
individual who pays interest on a mortgage not secured by real property in the
United States. Use Form W-8 or substitute form to notify the mortgage interest
recipient that the payer is a nonresident alien individual.
 
PORTFOLIO INTEREST. -- Generally, portfolio interest paid to a nonresident alien
individual or foreign partnership, estate, or trust is not subject to backup
withholding rules. However, if interest is paid on portfolio investments to a
beneficial owner that is neither a financial institution nor a member of a
clearing organization, Form W-8 or substitute form is required.
 
    Registered obligations not targeted to foreign markets qualify as portfolio
interest not subject to 30% withholding, but require the filing of Form W-8 or
substitute form. See Instructions to Withholding Agents on this page for
reporting rules.
 
    See Pub. 515, Withholding of Tax on Nonresident Aliens and Foreign
Corporations, for registered obligations targeted to foreign markets and when
Form W-8 or substitute form is not required on these payments.
 
BEARER OBLIGATIONS. -- The interest form bearer obligations targeted to foreign
markets is treated as portfolio interest and is not subject to 30% withholding.
Form W-8 or substitute form is not required.
 
DIVIDENDS. -- Any distribution or payment of dividends by a U.S. corporation
sent to a foreign address is subject to the 30% (or lower treaty) withholding
rate, but is not subject to backup withholding. Also, there is no backup
withholding on dividend payments made to a foreign person by a foreign
corporation. However, the 30% withholding (or lower treaty) rate applies to
dividend payments made to a foreign person by a foreign corporation if:
 
- - 25% or more of the foreign corporation's gross income for the three preceding
taxable years was effectively connected with a U.S. trade or business, and
 
- - The corporation was not subject to the branch profits tax because of an income
tax treaty (see section 884(e)).
 
    If a foreign corporation makes payments to another foreign corporation, the
recipient must be a qualified resident of its country of residence to benefit
from that country's tax treaty.
 
BROKER OR BARTER EXCHANGES. -- Income from transactions with a broker or barter
exchanges is subject to reporting rules and backup withholding unless Form W-8
or substitute form is filed to notify the broker or barter exchange that you are
an exempt foreign person as defined on page 1.
 
SPECIFIC INSTRUCTIONS
 
NAME OF OWNER. -- If Form W-8 is being filed for portfolio interest, enter the
name of the beneficial owner.
 
U.S. TAXPAYER IDENTIFICATION NUMBER. -- If you have a U.S. taxpayer
identification number, enter your number in this space (see the discussion
earlier).
 
PERMANENT ADDRESS. -- Enter your complete address in the country where you
reside permanently for income tax purposes.

If you are:             Show the
                        address of:
An individual           Your permanent
                        residence
A partnership           Principal office
or corporation
An estate or            Permanent residence

                        of any fiduciary
</TABLE>
 
    Also show your current mailing address if it differs from your permanent
address.
 
ACCOUNT INFORMATION (OPTIONAL). -- If you have more than one account (savings,
certificate of deposit, pension, IRA, etc.) with the same payer, list all
account numbers and types on one Form W-8 or substitute form unless your payer
requires you to file a separate certificate for each account.
 
    If you have more than one payer, file a separate Form W-8 with each payer.
 
SIGNATURE. -- If only one foreign person owns the account(s) listed on this
form, that foreign person should sign the Form W-8.
 
    If each owner of a joint account is a foreign person, each should sign a
separate Form W-8.
 
NOTICE OF CHANGE IN STATUS. -- If you become a U.S. citizen or resident after
you have filed Form W-8 or substitute form, or you cease to be an exempt foreign
person, you must notify the payer in writing within 30 days of your change in
status.
 
    To notify the payer, you may check the box in the space provided on this
form or use the method prescribed by the payer.
 
    Reporting will then begin on the account(s) listed and backup withholding
may also begin unless you certify to the payer that:
 
    (1) The U.S. taxpayer identification number you have given is correct, and
 
    (2) The Internal Revenue Service has not notified you that you are subject
to backup withholding because you failed to report certain income.
 
    You may use Form W-9, Request for Taxpayer Identification Number and
Certification, to make these certifications.
 
    If an account is no longer active, you do not have to notify a payer of your
change in status unless you also have another account with the same payer that
is still active.
 
FALSE CERTIFICATE. -- If you file a false certificate when you are not entitled
to the exemption from withholding or reporting, you may be subject to fines
and/or imprisonment under U.S. perjury laws.
 
INSTRUCTIONS TO WITHHOLDING AGENTS
 
WITHHOLDING AGENT. -- Generally, the person responsible for payment of the items
discussed above to a nonresident alien individual or foreign entity is the
withholding agent (see Pub. 515).
 
RETENTION OF STATEMENT. -- Keep Form W-8 or substitute form in your records for
at least four years following the end of the last calendar year during which the
payment is paid or collected.
 
PORTFOLIO INTEREST. -- Although registered obligations not targeted to foreign
markets are not subject to 30% withholding, you must file Form 1042S. Foreign
Person's U.S. Source Income Subject to Withholding, to report the interest
payment. Both Form 1042S and a copy of Form W-8 or substitute form must be
attached to Form 1042, Annual Withholding Tax Return for U.S. Source Income of
Foreign Persons.

                             BMC SOFTWARE, INC.

        BMC Software, Inc., a Delaware corporation ("Purchaser"), hereby offers
to purchase all the outstanding ordinary shares, NIS 0.01 par value per share
(the "Shares"), of New Dimension Software Ltd., an Israeli corporation (the
"Company"), at a purchase price of $52.50 per Share, net to the seller in cash,
without interest thereon, upon the terms and subject to the conditions set
forth in the Offer to Purchase, dated March 11, 1999 (the "Offer to Purchase"),
and the related Letter of Transmittal (which, together with the Offer to
Purchase and any amendments or supplements thereto, collectively constitute the
"Offer"). See the Offer to Purchase for capitalized terms used but not defined
herein. Following the Offer, the Purchaser intends to effect the Compulsory
Acquisition described below.

 -----------------------------------------------------------------------------
   THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK
    CITY TIME, ON THURSDAY, APRIL 8, 1999, UNLESS THE OFFER IS EXTENDED.
 -----------------------------------------------------------------------------

        The Offer is conditioned upon, among other things, (i) there being
validly tendered and not withdrawn prior to the Expiration Date (defined below)
a number of Shares which constitutes at least ninety percent (90%) of the Shares
then issued and outstanding and not owned by Purchaser or its subsidiaries
determined in accordance with Section 236 of the Companies' Ordinance (New
Version) 5743-1983 of the State of Israel (the "Companies' Ordinance"), (ii)
satisfaction of certain regulatory conditions, including the expiration or
termination prior to the expiration of the Offer of all waiting periods imposed
by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the
"HSR Act"), (iii) certain approvals related to the Offer by the shareholders of
the Company at a Special Meeting as described in the Offer to Purchase, and (iv)
certain other conditions. See Sections 1 and 14 of the Offer to Purchase.

        The Offer is being made pursuant to a Share Purchase and Tender
Agreement (the "Tender Agreement") dated as of March 7, 1999, by and between
Purchaser and the Company, which provides for certain agreements between the
Company and Purchaser relating to the Offer. Concurrently with the execution of
the Tender Agreement, Purchaser entered into Shareholder Agreements, each dated
March 7, 1999 (the "Shareholder Agreements"), with Yossie Hollander and with
Roni A. Einav, Dalia Prashker-Katzman and Einav Computer Systems, an Israeli
corporation (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 61.0% of the
issued and outstanding Shares, (b) the Principal Shareholders have granted to
Purchaser an irrevocable option to purchase all of such Shares in certain
circumstances, and (c) each Principal Shareholder has granted to Purchaser 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 Tender Agreement and the Shareholder Agreements are more fully
described in Section 12 of the Offer to Purchase.

        If Purchaser is successful in acquiring in the Offer at least ninety
percent (90%) of the Shares not presently owned by it or its subsidiaries within
four months of the date hereof (the "Initial Period"), Purchaser has agreed in
the Tender Agreement, in accordance with Section 236 of the Companies'
Ordinance, to 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 Purchaser has agreed to deliver the Notice of Acquisition at any
time during the two month period following the Initial Period. See Section 1 of
the Offer to Purchase for more details on the Compulsory Acquisition.

        THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY DETERMINED THAT,
AS OF THE DATE OF THE TENDER AGREEMENT, THE OFFER IS FAIR TO AND IN THE BEST
INTERESTS OF THE SHAREHOLDERS OF THE COMPANY AND RESOLVED, SUBJECT TO THE
RECEIPT OF CERTAIN SHAREHOLDER APPROVALS RELATING TO THE OFFER AS DESCRIBED IN
THE OFFER TO PURCHASE, TO RECOMMEND ACCEPTANCE OF THE OFFER BY THE SHAREHOLDERS
OF THE COMPANY.

        For purposes of the Offer, Purchaser will be deemed to have accepted for
payment (and thereby purchased) Shares validly tendered prior to the Expiration
Date and not properly withdrawn as, if and when Purchaser gives oral or written
notice to BankBoston N.A., as the Depositary (in such capacity, the
"Depositary"), of Purchaser's acceptance of such Shares for payment. In all
cases, payment for Shares purchased pursuant to the Offer will be made by
deposit of the purchase price therefor with the Depositary, which will act as
agent for tendering shareholders for the purpose of receiving payment from
Purchaser and transmitting payment to tendering shareholders whose Shares have
theretofore been accepted for payment. In all cases, payment for Shares
purchased pursuant to the Offer will be made only after timely receipt by the
Depositary of (i) certificates for such Shares (or a confirmation of a
book-entry transfer of Shares into the Depositary's account at The Depository
Trust Company (the "Book-Entry Transfer Facility") pursuant to the procedures
set forth in Section 3 of the Offer to Purchase), (ii) the Letter of Transmittal
(or a manually signed facsimile thereof), properly completed and duly executed
with all required signature guarantees, or in the case of a book-entry transfer,
an Agent's Message (as defined in the Offer to Purchase), and (iii) all other
documents required by the Letter of Transmittal. Under no circumstances will
interest on the Offer Price be paid by the Purchaser, regardless of any
extension of the Offer or delay in making such payment.

        The term "Expiration Date" shall mean 12:00 Midnight, New York City
time, on Thursday, April 8, 1999, unless and until Purchaser, in accordance with
the terms of the Offer, shall have extended the period of time during which the
Offer is open, in which event the term "Expiration Date" shall mean the latest
time and date at which the Offer, as so extended by Purchaser, shall expire. 

        Subject to the terms of the Tender Agreement, Purchaser expressly
reserves the right, in its sole discretion, at any time or from time to time, to
extend the period of time during which the Offer is open by giving oral or
written notice of such extension to the Depositary and by making a public
announcement of such extension. There can be no assurance that Purchaser will
exercise its right to extend the Offer. Purchaser also expressly reserves the
right, subject to applicable laws (including applicable regulations of the
Securities and Exchange Commission promulgated under the Securities Exchange Act
of 1934), and to the terms of the Tender Agreement, at any time or from time to
time, (i) to delay acceptance for payment of or payment for any Shares,
regardless of whether the Shares were theretofore accepted for payment, or to
terminate the Offer and not accept for payment or pay for any Shares not
theretofore accepted for payment or paid for, upon the occurrence of any of the
conditions specified in Section 14 of the Offer to Purchase, by giving oral or
written notice of such delay in payment or termination to the Depositary, and
(ii) to amend the Offer in any respect, by giving oral or written notice to the
Depositary. Any extension, amendment or termination of the Offer, any waiver of
any condition of the Offer, or any delay in payment, will be followed as
promptly as practicable by a public announcement. In the case of an extension,
such announcement must be issued no later than 9:00 a.m., New York City time, on
the next business day after the previously scheduled Expiration Date. Without
limiting the manner in which Purchaser may choose to make any public
announcement, Purchaser will have no obligation to publish, advertise or
otherwise communicate any such announcement other than by issuing a press
release to the Dow Jones News Service (or a similar news service) or as
otherwise may be required by law.

        Tenders of Shares made pursuant to the Offer are irrevocable, except as
otherwise provided below. Shares tendered pursuant to the Offer may be withdrawn
any time prior to the Expiration Date and, unless theretofore accepted for
payment by Purchaser, may also be withdrawn at any time after May 9, 1999. For a
withdrawal to be effective, a written, telegraphic or facsimile transmission
notice of withdrawal must be timely received by the Depositary at one of its
addresses set forth on the back cover of the Offer to Purchase. Any such notice
of withdrawal must specify the name of the person who tendered the Shares to be
withdrawn, the number of Shares to be withdrawn and the name of the registered
holder, if different from that of the person who tendered such Shares. If
certificates evidencing Shares to be withdrawn have been delivered or otherwise
identified to the Depositary, then prior to the release of such certificates,
the tendering shareholder must also submit the serial numbers shown on the
particular certificates evidencing the Shares to be withdrawn, and the signature
on the notice of withdrawal must be guaranteed by an Eligible Institution (as
defined in Section 3 of the Offer to Purchase) (except in the case of Shares
tendered for the account of an Eligible Institution). If Shares have been
tendered pursuant to the procedures for book-entry transfer set forth in Section
3 of the Offer to Purchase, the notices of withdrawal must specify the name and
number of the account at the applicable Book-Entry Transfer Facility to be
credited with the withdrawn Shares and otherwise comply with such Book-Entry
Transfer Facility's procedures. 

        All questions as to form and validity (including time of receipt) of
notice of withdrawal will be determined by Purchaser, in its sole discretion,
whose determination shall be final and binding on all parties. No withdrawal of
Shares shall be deemed to have been properly made until all defects and
irregularities have been cured or waived. None of Purchaser, the Dealer
Managers, the Depositary, the Information Agent or any other person will be
under any duty to give notification of any defects or irregularities in any
notice of withdrawal or incur any liability for failing to give such
notification.

        The Company has provided Purchaser with its shareholder list and
security position listings for the purpose of disseminating the Offer to
shareholders. The Offer to Purchase, the related Letter of Transmittal and other
relevant materials will be mailed to record holders of Shares and will be
furnished to brokers, dealers, commercial banks, trust companies and similar
persons whose names, or the names of whose nominees, appear on the Company's
shareholder list, or, if applicable, who are listed as participants in a
clearing agency's security position listing, for subsequent transmittal to
beneficial owners of Shares by Purchaser.

        The information required to be disclosed by Rule 14d-6(e)(1)(vii) of the
General Rules and Regulations under the Securities Exchange Act of 1934 is
contained in the Offer to Purchase and is incorporated herein by reference.

        THE OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN

forth below, and copies will be furnished promptly at the Purchaser's expense.

                 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

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.

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.

FOR IMMEDIATE RELEASE

NEW DIMENSION SOFTWARE ANNOUNCES RECORD REVENUES AND EARNINGS FOR THE 
FOURTH QUARTER AND YEAR 1998

Revenues for the Quarter Increased by 62.9 Percent; Net Income Increased by
100.4 Percent TEL AVIV, Israel, February 3, 1999 -- New Dimension Software, Ltd.
(NASDAQ: DDDDF) today announced record revenues and net income for the fourth
quarter and the year ended December 31, 1998. Total revenues for the quarter
ended December 31, 1998 were $30,012,000, a 62.9 percent increase as compared
to $18,425,000 in the same period last year. Net income for the quarter
increased by 100.4 percent to $6,833,000 (or $0.53 per diluted share), as
compared to net income of $3,410,000 (or $0.27 per diluted share) for the same
period last year.

Total revenues for the year ended December 31, 1998 were $93,591,000, a 44.1
percent increase as compared to $64,969,000 in 1997. Net income for the year
ended December 31, 1998 increased by 87.2 percent to $20,530,000 (or $1.59 per
diluted share), as compared to net income of $10,966,000 (or $0.- 89 per
diluted share) for the same period last year.

On a geographic basis, revenues for the fourth quarter increased by 101.4
percent in North America, by 21.7 percent in Europe, and by 17.2 percent in the
rest of the world. 

Revenues derived from product sales reached record levels during the fourth
quarter, growing by 80.8 percent as compared to the same period last year. The
revenues from sales of client/server products as a percentage of total product
sales were 65 percent in the fourth quarter. 

Maintenance revenues also reached record levels during the fourth quarter, and
grew by 27.2 percent as compared to the same period last year.

"We are very pleased with the performance of the Company during the fourth
quarter and throughout 1998," said Dan Barnea, the Company's CEO. "During the
quarter, we signed seven contracts valued at more than $1 million. We are
pleased to see that a growing number of new and existing customers are signing
large, long-term contracts with us, which we believe reflects a strong
commitment from our customers to the technology and to the Company. We also
believe that long-term contracts provide us with a strategic advantage in these
accounts, enhancing our opportunity for future product sales." "We are very
pleased with the sales and market acceptance of CONTROL-SA(TM), which we
regard as among the year's most important achievements," Mr. Barnea said.
"During the fourth quarter, CONTROL-SA revenues increased by 1,701 percent over
the same period in 1997, and reached $4,302,000. The number of CONTROL-SA
customers has more than doubled this year. We expect demand for this important
product line to accelerate in 1999, and we are focusing significant development
and marketing resources on CONTROL-SA to take advantage of this market
opportunity."

Mr. Barnea continued, "We continue to see strong demand for client/server
products across all three major product lines. We believe this trend will
continue into 1999 as well, fueled by the growing number of organizations
adopting client/server production applications to address year 2000 concerns.
With all major product lines performing on UNIX, Windows NT and many additional
platforms, we believe we are well positioned for this market trend." 

"On a geographic basis, the Company continues to be led by the success of the
North American organization," he continued. "We attribute the success of this
organization to the stability and experience of the Company's North American
sales force." Mr. Barnea added, "In other regions of the world, we are pleased
to note the success of our new subsidiary company in Mexico, which opened in
April 1998. During the fourth quarter, this newly formed organization signed the
Company's two largest contracts to date from Latin America, together totaling
$2,750,000. Revenues from Mexico reached record levels during 1998."

"A major achievement of 1998 has been the strengthening of our strategic
relationships with other vendors," he continued. "We are very pleased with the
results of our Alliance Partner Program, which has expanded our reach into
renowned organizations such as IBM, SAP, Oracle and others with which the
Company has formal joint marketing and technology initiatives."

Mr. Barnea said, "As we enter 1999, the Company is embarking on a number of
strategic technology initiatives to advance the product line, focusing on the
Internet and its increasing importance in the enterprise. We are currently in
the final Beta testing stages of three new Internet-based products:
CONTROL-M(R)/Web ACCESS(TM), CONTROL-SA/Workflow(TM) and
CONTROL-SA/Passport(TM). CONTROL-M/Web Access is a new option that allows remote
access to CONTROL-M using any standard Web browser. CONTROL-SA/Workflow
automates the resource-intensive authorization process for new employees
requiring access to internal computing resources, or for existing employees who
require

<PAGE>   2
changes to their access rights. CONTROL-SA/PassPort allows end users to issue
single change requests using a Web browser to change and synchronize all of
their passwords across the enterprise. We are very enthusiastic about the
prospect of adding these new products to our product line and about the many
other technology initiatives underway. We will continue to focus resources on
the development of strategic tools for the Internet and other key enterprise
technologies."

Houston, Texas 77042

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.

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.

Borrower or any affiliate thereof, (f) the negotiation, execution and delivery

commitment hereunder and of the Facility are not limited to those set forth

agreement of Chase, CSI and the Borrower.

     You agree to indemnify and hold harmless Chase, CSI, the other Lenders,

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 ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF ANY INDEMNIFIED PERSON. You
also agree to reimburse Chase, CSI and their affiliates on demand for all
out-of-pocket expenses (including syndication expenses, travel expenses, and
reasonable fees, charges and disbursements of counsel) incurred in connection
with the Facility and any related documentation (including this Commitment
Letter, the Term Sheet, the Fee Letter and the definitive financing
documentation) or the administration, amendment, modification or waiver
thereof. No indemnified person shall be liable for any damages arising from the
use by others of Information or other materials obtained through electronic,
telecommunications or other information transmission systems or for any

in accordance with, the laws of the State of Texas.

         This Commitment Letter is delivered to you on the understanding that
neither this Commitment Letter, the Term Sheet or the Fee Letter nor any of

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,

the transactions described herein and otherwise. Neither CSI nor Chase will use

                        the gross negligence or willful misconduct of the
                        indemnified party).

                            (both drawn and undrawn portion), in the amount of
                            applicable Facility Fee determined in accordance
                            with the attached Pricing Grid. The Facility Fee is

                            Facility that is made to it will bear interest at a
                            rate equal to the Applicable Margin, as determined

                           [ABN-AMRO BANK LETTERHEAD]



March 9, 1999

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.

                                    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.

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

Schedule, the 1998 Preliminary Statements and the 1998 Audited Statements will
not differ in any material respect.

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
Internally Developed Software or related technical documentation and all such

Schedule contains a complete list of material Third Party Distributed Software.
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.

Effect. The Company has all permits, licenses, orders, approvals, franchises and
other rights and privileges ("Permits") necessary in order for it to carry on
its business as presently conducted, except such Permits which no governmental

cause its affiliates, directors, officers, employees, agents or representatives

which such party is bound if it has used commercially reasonable efforts to
consult with the other parties and to obtain such parties' consent but has been
unable to do so in a timely manner.

         5.8. Acquisition Proposals.

         (a) Subject to Section 5.8(b) below, the Company shall not (and shall
not permit any of its subsidiaries to, and shall use its best efforts to cause
its officers, directors and employees and any investment banker, attorney,
accountant, or other agent retained by it or any of its subsidiaries not to)

(including by way of furnishing information) any inquiry or the making of any
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, or furnish to another person (other than Purchaser or a representative

Agreement shall prohibit the Company from (i) furnishing information pursuant to
an appropriate confidentiality letter concerning the Company and its businesses,
properties or assets to a third party who has made a Superior Proposal (as
defined below), (ii) engaging in discussions or negotiations with a third party
who has made a Superior Proposal or (iii) following receipt of a Superior
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,
that such action is necessary in order for the Board of Directors of the Company
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
Company Transaction Proposal, then the Company shall immediately inform
Purchaser of the terms and conditions of such proposal and the identity of the
person making it and shall keep Purchaser fully informed of the status and
details of any such Company Transaction Proposal and of all steps

it is taking in response to such Company Transaction Proposal. For purposes of
this Agreement, the term "Superior Proposal" shall mean a bona fide Company
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.

         (c) If (i) this Agreement is terminated by Purchaser pursuant to
Section 6.1(e)(ii) hereof or by the Company pursuant to Section 6.1(f) hereof,
or (ii) (A) prior to the Closing Date, there is publicly announced by a third
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

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)

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

plans, programs and arrangements generally provided to similarly situated

         (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

right to terminate this Agreement under this clause (b) shall not be available

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

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

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

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

costs and expenses incurred in connection with this Agreement and the

                             CONDITIONS TO THE OFFER

         Capitalized terms used in this Exhibit A shall have the meanings
assigned to them in the Agreement to which it is attached (the "Tender

         Purchaser shall not be required to accept for payment, purchase or pay
for any Shares tendered and Purchaser may terminate or, subject to the terms and
conditions of the Tender Agreement, amend the Offer as to any Shares not then
accepted for payment, shall not be required to accept for payment or pay for any

from, governmental and regulatory authorities in connection with the Offer and
the consummation of the other transactions contemplated hereby which are listed

Agreement shall not have occurred;

         (3) the Shareholder Approvals shall not have been obtained at the

all Company Options in accordance with Section 2.1(a) of the Tender Agreement

subsidiaries at the Closing Date;

         (5) the Director Releases shall not have become effective in accordance

         before any court or governmental, administrative or regulatory
         authority or agency, located or having jurisdiction within the United
         States or State of Israel, or any other action taken, proposed or
         threatened, or statute, rule, regulation, legislation, interpretation,
         judgment or order proposed, sought, enacted, entered, enforced,
         promulgated,

         amended, issued or deemed applicable to Purchaser, the Company or any
         subsidiary or affiliate of Purchaser or the Company or the Offer, by
         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
         or otherwise restraining or prohibiting the Offer or the acquisition by
         Purchaser of any Shares or the Compulsory Acquisition; (ii) prohibiting
         or materially limiting the ownership or operation by Purchaser or its
         affiliates of any material portion of the business or assets of the
         Company or compelling Purchaser to dispose of or hold separate all or
         any material portion of the business or assets of the Company, in each
         case as a result of the transactions contemplated by the Tender
         Agreement; (iii) imposing material limitations on the ability of
         Purchaser or any of its affiliates to exercise full rights of ownership
         of the Shares, including, without limitation, the right to vote any
         Shares purchased by them on all matters properly presented to the
         shareholders of the Company; or (iv) preventing Purchaser or any of its
         affiliates from acquiring, or to require divestiture by Purchaser or
         any of its affiliates of, any Shares in the Offer; or

         be expected to have, a substantial continuing general effect on
         business and financial conditions in Israel; or

                  (c) any Person, entity or "group" (as such term is used in
         Section 13(d)(3) of the Exchange Act) other than Purchaser or any of

         specifying in reasonable detail the basis of such alleged breach), (ii)
         or any representation or warranty of the Company contained in the

         warranties (without giving effect to any limitation based on
         materiality or Material Adverse Effect or words of similar effect set
         forth therein) to be true and correct would not, in the aggregate,
         reasonably be expected to have a Material Adverse Effect; or

                  (e) there shall have occurred a Material Adverse Effect, other
         than as a result of the transactions specifically contemplated by the
         Tender Agreement; or

                  (f) the Tender Agreement shall have been terminated pursuant
         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.

reasonably be expected to, implement or lead to any Company Transaction

                           (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
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 of the Company, and

                                    (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
the Tender Agreement, the Offer or any Company Transaction Proposal. Shareholder

granted by Shareholder with respect to his Applicable Shares.

                  (c) From and after the date of this Agreement and ending as of
the Termination Date, Shareholder shall not take any action (including the

                  (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

hereby agrees that he shall not exercise any Company Options that he

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 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

                  (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.

         5.1 Escrow Agreement. As further set forth in the Escrow Agreement

with the Escrow Agent) shall be placed with Meitar, Liquornik, Geva & Co. as
escrow agent within five business days of the date hereof and ending on the
Termination Date, to be disbursed as set forth below.

         5.2 Release and Delivery. The Applicable Shares shall be released and
delivered during the term hereof at any time or from time to time, (i) to
Purchaser in connection with the purchase of such Shares pursuant to this
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.

                                   ARTICLE VII
                    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

<PAGE>   10




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
into any contract, option or other arrangement or understanding with respect to
or consent to the offer for sale, sale, transfer, tender, pledge, encumbrance,
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
as follows:

                  (a) Organization, Standing and Corporate Power. Purchaser is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware, with adequate corporate power and authority to own its
properties and carry on its business as presently conducted. Purchaser has the
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
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.

                                  ARTICLE VIII
                                  MISCELLANEOUS

         8.1 Stop Transfer. From and after the date of this Agreement and ending
as of the Termination Date, Shareholder will not request that Company register
the transfer (book-entry or otherwise) of any certificate or uncertificated
interest representing any of Shareholder's Applicable Shares or Company Options,
except as otherwise contemplated hereby.

         8.2 Recapitalization. In the event of a stock dividend or distribution,
or any change in the Shares by reason of any split-up, recapitalization,
combination, exchange of shares or the like, the term "Shares" shall include,
without limitation, all such stock dividends and distributions and any
securities into which or for which any or all of the Applicable Shares may be
changed or exchanged as may be appropriate to reflect such event.

         8.3 Shareholder Capacity. Except as set forth in Section 7.3,
Shareholder does not make any agreement or understanding herein in his capacity
as a director or officer of Company and nothing herein shall limit or affect any
action taken by Shareholder in such capacity. Nothing herein shall in any way
restrict or limit Shareholder from taking any action in his capacity as a
director or officer of Company or otherwise fulfilling his fiduciary obligations
as a director and officer of Company.

         8.4 Tender Agreement and Company Options. Shareholder hereby consents
and agrees to the treatment of Company Options Beneficially Owned by Shareholder
or his affiliates as set forth in the Tender Agreement.

         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,

 
                                       12

<PAGE>   13




illegality or unenforceability will not affect any other provision or portion of

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.

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.

or any other material obligation or agreement of Company under the Tender
Agreement or this Agreement;

                           (ii) against the following actions (other than the

<PAGE>   4




                                    (B) to the extent that such (1) are intended
to, or could reasonably be expected to, impede, interfere with, delay, postpone,
or materially adversely affect the Offer, or the transactions contemplated by
the Tender Agreement or this Agreement or (2) are intended to, or could
reasonably be expected to, implement or lead to any Company Transaction

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

approval in respect of its Applicable Shares on any and all matters relating to

                  (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
Shareholder Group shall repay Purchaser the amount of such advance, without
interest, immediately upon receipt of the Per Share Amount by it for its
Underlying Shares.

                  (c) Except as may be required by Section 2.2(b), Shareholder
Group hereby agrees that it shall not exercise any Company Options that it

terms and subject to the conditions set forth herein, at the Per Share Amount

         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
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.

                  (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

<PAGE>   7




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.

                                    ARTICLE V

delivered during the term hereof at any time or from time to time, (i) to
Purchaser in connection with the purchase of such Shares pursuant to this
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.

                                   ARTICLE VII
                                     RELEASE

This Agreement has been duly and validly authorized by all necessary action,
executed and delivered by Shareholder Group and constitutes a valid and binding
agreement of Shareholder Group, enforceable against Shareholder Group 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 Group is trustee
whose consent is required for the execution and delivery of this Agreement or
the consummation by Shareholder Group of the transactions contemplated hereby.
If either Owner is married and such Owner's interest in Shareholder Group's
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.
The Owners are the sole owners of ECS.

Shareholder Group'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 Group
and the consummation by Shareholder Group of the transactions contemplated
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
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 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.

                                  ARTICLE VIII

Shares or Company Options, except as otherwise contemplated hereby.

         8.2 Recapitalization. In the event of a stock dividend or distribution,
or any change in the Shares by reason of any split-up, recapitalization,
combination, exchange of shares or the like, the term "Shares" shall include,
without limitation, all such stock dividends and distributions and any
securities into which or for which any or all of the Applicable Shares may be
changed or exchanged as may be appropriate to reflect such event.

         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

well as the mutual promises set forth herein, and for other good and valuable

         3.4 Severability. Whenever possible, each provision or portion of any

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.

         3.5 Third Party Beneficiary. This agreement is intended to be for the
benefit of, and shall be enforceable by, Purchaser. In the event of Director's
death, the benefits and obligations of Director hereunder shall inure to his
successors and heirs.

         3.6 Specific Performance. Each of the parties hereto recognizes and
acknowledges that a breach by a Director of any covenants or agreements
contained in this Agreement will cause Company and 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 Company or Purchaser shall be entitled to the remedy of specific performance
of such covenants and agreements and injunctive and other equitable relief in
addition to any other remedy to which they may be entitled, at law or in equity.

         3.7 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.

         3.8 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.

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

         3.10 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.

         3.11 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.
