To the Holders of Common Stock of            
  CHEYENNE SOFTWARE, INC.:            
            
                           INTRODUCTION            
            
     Tse-tsehese-staestse, Inc., a Delaware corporation ("Merger   
Subsidiary") and a wholly owned subsidiary of Computer Associates     
International, Inc., a Delaware corporation ("Computer Associates"), hereby
offers to purchase all outstanding shares of Common Stock, par value $.01 per
share (including the associated Rights (defined below) (collectively, except
where the context otherwise requires, the "Shares"), of Cheyenne Software,
Inc., 
a Delaware corporation (the "Company"), at $30.50 per Share, 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").  Tendering stockholders of the Company (the stockholders of  the
Company are referred to herein as the "Stockholders") will not be obligated
to pay brokerage fees or commissions or, except as set forth in the Letter
of Transmittal, transfer taxes on the purchase of Shares pursuant to the
Offer.  Computer Associates will pay all charges and expenses of The Bank of
New York 
(the "Depositary") and D.F. King & Co., Inc. (the "Information Agent") in
connection with the Offer.           
           
     The Board of Directors of the Company has unanimously determined that
the Offer and the transactions contemplated by the Merger Agreement (defined
below) are fair to, and in the best interests of, the Stockholders of the
Company, has unanimously approved the Offer and the transactions contemplated
by the Merger 
Agreement, and unanimously recommends that the Stockholders of the Company
accept the Offer and tender their Shares.            
            
     Pursuant to the Merger Agreement, the Company has represented to
Computer Associates that Lazard Freres & Co. LLC ("Lazard Freres"), the
Company's financial advisor, has delivered to the Company's Board of
Directors its written opinion to the effect that the $30.50 per Share to  be
paid in the Offer and the 
Merger is fair to the holders of the Shares  from a financial point of view. 
The opinion of Lazard Freres is set forth in 
full in the Company's Solicitation/Recommendation Statement on  Schedule
14D-9 (the "Schedule 14D-9"), being mailed to Stockholders with this Offer
to Purchase.  Stockholders are urged to read this opinion in its entirety. 
          
            
     The Offer is conditioned upon, among other things, (1) there being
validly tendered by the Expiration Date (defined below) and not withdrawn a
number of Shares which, together with the Shares then owned by Computer
Associates and Merger Subsidiary, would represent at least a majority of the
total number of outstanding Shares, assuming the exercise of all outstanding
options, rights and convertible securities (if any) and the issuance of all
Shares that the Company is obligated to  issue (such total number of
outstanding Shares being hereinafter referred to as the "Fully Diluted
Shares") (the "Minimum Condition") and (2) the expiration or termination of
the applicable waiting period under the 
Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR            
Act").  See Section 15, which sets forth in full the conditions to the Offer. 
          
           
<PAGE> 2            
           
     The Company has represented to Computer Associates that, as of October
7, 1996, there were 37,711,424 Shares issued and outstanding, and 5,003,136
Shares reserved for issuance upon the exercise of stock options outstanding
under various employee and director stock option plans.  Based upon the
foregoing, as of October 7, 1996, there were approximately 42,714,560 Shares
outstanding on a fully diluted basis. Neither Computer Associates nor Merger
Subsidiary owns any Shares.  Accordingly, Computer Associates believes that
the Minimum Condition  would be satisfied (based on the foregoing
assumptions) if approximately  21,357,281 Shares are validly tendered
pursuant to the Offer and not withdrawn.            
            
     The Offer is being made pursuant to an Agreement and Plan of          
 
Merger, dated as of October 7, 1996 (the "Merger Agreement"), among the
Company, Computer Associates and Merger Subsidiary, which has been
unanimously approved by the Company's Board of Directors.  The Merger
Agreement provides, among other things, that, after consummation of the 
Offer, and upon the later of (i) November 30, 1996, provided that as of such
date the conditions to the Merger set forth in the Merger Agreement shall be
fulfilled or waived and (ii) the first business day on which such conditions
to the Merger shall be fulfilled or waived, Merger Subsidiary will be merged
into the Company (the "Merger"), with the            
Company continuing as the surviving corporation (the "Surviving            
Corporation").  Pursuant to the Merger Agreement, at the effective time of
the Merger (the "Effective Time"), each outstanding Share (other than  Shares
owned by Computer Associates, Merger Subsidiary or any subsidiary  of either
of them or held by the Company as treasury stock (which shall  be canceled)
or by Stockholders exercising appraisal rights under  Delaware Law (defined
below)) will be converted into the right to            
receive $30.50 in cash or any higher price paid for each Share in the Offer,
without interest.  If the Minimum Condition is satisfied and  Merger
Subsidiary purchases Shares pursuant to the Offer, Merger Subsidiary will
have the power to approve the Merger without the affirmative vote of any
other Stockholder.  In the event that Merger Subsidiary owns 90% or more of
the Shares then outstanding,  the "short-form" merger provisions of the
Delaware General Corporation Law ("Delaware Law") would permit the Merger to
occur without a meeting  or a vote of the Stockholders.  See Section 11.   
        
            
     Pursuant to the Merger Agreement, at the Effective Time, all          
  
outstanding stock options under the Company's various stock option plans
shall by virtue of the Merger become fully exercisable and vested and be
assumed by Computer Associates.  See Section 11.            
            
     In connection with the execution of the Merger Agreement, the Company
amended its Rights Agreement, dated as of April 15, 1996, as amended (the
"Rights Agreement"), between the Company and Continental Stock Transfer &
Trust Company, as Rights Agent, to make it and the Preferred Share Purchase
Rights issued thereunder (the "Rights") inapplicable to the Offer and the
Merger.  See Section 11.            
            
     Upon acceptance for payment by Merger Subsidiary of such number of
Shares which satisfies the Minimum Condition, Computer Associates is
entitled, pursuant to the Merger Agreement, to designate the number of
directors, rounded up to the next whole number, on the Company's Board of
Directors that equals the product of (i) the total number of directors on the
Company's Board of Directors and (ii) the percentage that the number of
Shares owned by Computer Associates or Merger Subsidiary (including Shares
accepted for payment) bears to the total            
number of Shares outstanding, and the Company shall take all necessary action
to cause Computer Associates' designees to be elected or
           
<PAGE> 3           
           
appointed to the Company's Board of Directors; provided that, prior to the
Effective Time, the Company's Board of Directors shall always have one member
who is neither a designee nor an affiliate of Computer Associates or Merger
Subsidiary nor an employee of the Company (an "Independent Director").  No
action proposed to be taken by  the Company to amend or terminate the Merger
Agreement or waive any action by Computer Associates or Merger Subsidiary
shall be effective without the approval of the Independent Director.       
    
            
     THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL          
 
CONTAIN IMPORTANT INFORMATION WHICH SHOULD BE READ BEFORE ANY DECISION IS
MADE WITH RESPECT TO THE OFFER.            
            
            
            
1.   Terms of the Offer.              
            
     Upon the terms and subject to the conditions set forth in the         
  
Offer, Merger Subsidiary will accept for payment and purchase, at the time
and in the manner set forth in Section 2, all Shares that are validly
tendered by the Expiration Date and not withdrawn as provided in  Section 4. 
Unless and until certificates representing Rights ("Rights Certificates") are
issued, a tender of Shares pursuant to the Offer will constitute a tender of
associated Rights evidenced by the certificates for such Shares.  The term
"Expiration Date" shall mean 12:00 Midnight,            
New York City time, on Friday, November 8, 1996, unless Merger            
Subsidiary shall have extended the period of time for 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 Merger Subsidiary, shall
expire.            
            
     The Offer is subject to certain conditions set forth in Section 15,
including satisfaction of the Minimum Condition and expiration or termination
of the waiting period applicable to Merger Subsidiary's acquisition of Shares
pursuant to the Offer under the HSR Act.  If any such condition is not
satisfied, Merger Subsidiary may, except as otherwise described below, (i)
terminate the Offer and return all tendered Shares to tendering Stockholders,
(ii) extend the Offer and, subject to withdrawal rights as set forth in
Section 4, retain all such Shares until the expiration of the Offer as so
extended, (iii) waive such condition (except the Minimum Condition) and,
subject to any requirement to extend the period of time during which the
Offer is open,            
purchase all Shares validly tendered by the Expiration Date and not withdrawn
or (iv) delay acceptance for payment or payment for Shares, subject to
applicable law, until satisfaction or waiver of the conditions to the Offer. 
Notwithstanding the foregoing, but subject to Computer Associates' or the
Company's ability to terminate the Merger Agreement under certain
circumstances (described in Section 11 below), if the applicable waiting
period under the HSR Act shall not have expired or been terminated as of the
date the Offer would otherwise have expired, Merger Subsidiary has agreed,
pursuant to the Merger Agreement, to extend the Offer from time to time until
the earlier of (x) the date that is 30 days after the first scheduled
Expiration Date and (y) the            
date that such waiting period has expired or been terminated.              
For a description of Merger Subsidiary's right to extend the period of time
during which the Offer is open and to amend, delay or terminate the Offer,
see Section 14.  Merger Subsidiary acknowledges that Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), requires
Merger Subsidiary to pay the consideration offered or return the Shares
tendered promptly after the termination or withdrawal of the Offer.        
  
           
<PAGE> 4           
            
            
      Pursuant to the Merger Agreement, Computer Associates and Merger
Subsidiary expressly reserve the right to waive any of the conditions to the
Offer and to make any change in the terms or conditions of the Offer;
provided that, without the written consent of the Company, no change may be
made which changes the form of consideration to be paid in the Offer,
decreases the price per Share or the number of Shares being sought in the
Offer, imposes conditions to the Offer in addition to those expressly set
forth in the Merger Agreement, changes or waives the     
Minimum Condition, extends the Offer (except as set forth in the Merger
Agreement) or makes any other change to any condition to the Offer set  forth
in the Merger Agreement which is adverse to the holders of Shares.     
            
       Any extension, delay in payment, amendment or termination of the Offer
will be followed as promptly as practicable by public announcement thereof,
such announcement in the case of an extension to be made 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 Merger
Subsidiary may choose to make any public announcement, subject to applicable
law (including Rules 14d-4(c), 14d-6(d) and 14e-1        
under the Exchange Act which require that material changes be promptly
disseminated to stockholders in a manner reasonably designed to inform  them
of such changes), Merger Subsidiary shall have no obligation except as
otherwise required by applicable law) to publicly advertise  or otherwise
communicate any such public announcement other than by  issuing a release to
the Dow Jones News Service.            
            
        Subject to the Merger Agreement, if Merger Subsidiary makes any
material change in the terms of the Offer or the information concerning the
Offer, or waives any condition to the Offer that results in a material change
to the circumstances of the Offer, Merger Subsidiary will disseminate
additional tender offer materials and extend the Offer to the extent required
to comply with Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act. 
The Securities and Exchange Commission (the "Commission") has interpreted
such rules to prescribe that the minimum     
period during which an offer must remain open following material changes in
the terms of the offer or information concerning the offer, other than a
change in price or a change in percentage of securities sought, will depend
upon the facts and circumstances, including the relative materiality of the
terms or information changed.  With respect to a change in price or a change
in the percentage of securities sought, a minimum period of ten business days
may be required to allow for adequate dissemination to stockholders and
investor response.  As used in this Offer to Purchase, "business day" means
any day other than a Saturday, Sunday or a federal holiday and shall consist
of the time      
period from 12:01 a.m. through 12:00 midnight, New York City time.      
            
      The Company has provided Merger Subsidiary with the Company's
stockholder lists and security position listings for the purpose of
disseminating the Offer to holders of Shares.  This Offer to Purchase and the
related Letter of Transmittal will be mailed to record holders of Shares and
will be furnished to brokers, banks and similar persons  whose names, or the
names of whose nominees, appear on the stockholder 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.             
            
     Subject to the terms of the Offer and the satisfaction (or waiver to the
extent permitted by the Merger Agreement) of all the conditions  to the
Offer, Merger Subsidiary shall accept for payment all Shares  validly
tendered and not withdrawn pursuant to the Offer as soon as  practicable
after the expiration of the Offer and shall pay for all such shares promptly
after acceptance; provided that Merger Subsidiary may extend the Offer if,
at the scheduled expiration date of the Offer or  any extension thereof any
of the conditions to the Offer shall not have been 
satisfied, until such time as such conditions are satisfied or            
waived, and Merger Subsidiary may extend the Offer for a further period of
time of not more than 20 business days to meet the objective (which is not
a condition to the Offer) that there shall be validly tendered prior to the
Expiration Date (as so extended) and not withdrawn a number of Shares, which,
together with Shares then owned by Computer Associates and Merger Subsidiary,
represents at least 90% of the Fully Diluted            
Shares.  For a description of Merger Subsidiary's right to terminate the
Offer (subject to the terms of the Merger Agreement) and not accept for
payment or pay for Shares or to delay acceptance for payment or payment for
Shares, see Section 14.              
            
       For purposes of the Offer, Merger Subsidiary shall be deemed to  have
accepted for payment tendered Shares when, as and if Merger Subsidiary gives
oral or written notice to the Depositary of its  acceptance of the tenders
of such Shares.  In all cases, upon the terms  and subject to the conditions
of the Offer, payment for Shares accepted  for payment pursuant to the Offer
will be made by deposit of the  purchase price with the Depositary, which
will act as agent for the tendering Stockholders for the purpose of receiving
payments from Merger            
Subsidiary and transmitting such payments to tendering Stockholders.       
    
            
       In all cases, payment for Shares accepted for payment pursuant to the
Offer will be made only after timely receipt by the Depositary of (i)
certificates for such Shares (or of a confirmation of a book-entry transfer
(a "Book-Entry Confirmation") of such Shares into the Depositary's account
at one of the Book-Entry Transfer Facilities  (defined in Section 3)), (ii)
a properly completed and duly executed Letter
 of Transmittal (or facsimile thereof) or an Agent's Message            
(defined below) in connection with a book-entry transfer and (iii) any other
required documents.  Accordingly, payment may be made to tendering
Stockholders at different times if delivery of the Shares and other required
documents occur at different times.  For a description of the procedure for
tendering Shares pursuant to the Offer, see Section 3.  Under no
circumstances will interest be paid by Merger Subsidiary on the consideration
paid for Shares pursuant to the Offer, regardless of any delay in making such
payment.            
            
      The term "Agent's Message" means a message, transmitted by a Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of
a Book-Entry Confirmation, which states that such 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 Merger
Subsidiary may enforce such  agreement against such participant.           

           
<PAGE> 6           
            
        If Merger Subsidiary increases the consideration to be paid for
Shares pursuant to the Offer, Merger Subsidiary will pay such increased 
consideration for all Shares purchased pursuant to the Offer.            
            
        Merger Subsidiary reserves the right to transfer or assign, in whole
or from time to time in part, to one or more of Computer Associates or any
of its wholly owned subsidiaries, the right to  purchase Shares tendered
pursuant to the Offer, but any such transfer or  assignment will not relieve
Merger Subsidiary of its obligations under the Offer or prejudice the rights
of tendering Stockholders to receive payment for Shares validly tendered and
accepted for payment pursuant to  the Offer.   
            
      If any tendered Shares are not purchased pursuant to the Offer for any
reason, or if certificates are submitted for more Shares than are tendered,
certificates for such unpurchased or untendered Shares will be returned (or,
in the case of Shares tendered by book-entry transfer, such Shares will be
credited to an account maintained at one of the Book-Entry Transfer
Facilities), without expense to the tendering Stockholder, as promptly as
practicable following the expiration or termination of the Offer.     
            
3.   Procedure for Tendering Shares.              
            
     To tender Shares pursuant to the Offer, either (i) a properly         
   
completed and duly executed Letter of Transmittal (or facsimile            
thereof), or an Agent's Message in connection with a book-entry transfer of
such Shares, and any 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 and either (a)  certificates for such
Shares to be tendered must be received by the Depositary at one of such
addresses or (b) such Shares must be delivered    
pursuant to the procedures for book-entry transfer described below (and a
Book-Entry Confirmation received by the Depositary), in each case by the
Expiration Date, or (ii) the guaranteed delivery procedure described below
must be complied with.    
    
       The Depositary will establish an account with respect to the Shares
at The Depository Trust Company and Philadelphia Depository Trust Company
(collectively referred to as the "Book-Entry Transfer Facilities") for
purposes of the Offer within two business days after the date of this Offer
to Purchase, and any financial institution that  is a participant in the
system of any Book-Entry Transfer Facility may  make delivery of Shares by
causing such Book-Entry Transfer Facility to  transfer such Shares into the
Depositary's account in accordance with the procedures of such Book-Entry
Transfer Facility. However, although delivery of Shares may be effected
through book-entry transfer, the          
Letter of Transmittal (or facsimile thereof), or an Agent's Message in 
connection with such book-entry transfer, and any other required  documents
must, in any case, be received by the Depositary at one of its  addresses set
forth on the back cover of this Offer to Purchase by the Expiration Date, or
the guaranteed delivery procedure described below  must be complied with. 
Delivery of the Letter of Transmittal and any  other required documents to
a Book-Entry Transfer Facility does not            
constitute delivery to the Depositary.            
           
<PAGE> 7           
            
      Except as otherwise provided below, all signatures on a Letter of
Transmittal must be guaranteed by a bank, broker, dealer, credit union,    
savings association or other entity that is a member of a recognized
Medallion Program approved by The Securities Transfer Association, Inc. (an
"Eligible Institution").  Signatures on a Letter of Transmittal need       
    
not be guaranteed (i) if the Letter of Transmittal is signed by the        
   
registered holder of the Shares tendered therewith and such holder has     
      
not completed the box entitled "Special Payment Instructions" or the box   
        
entitled "Special Delivery Instructions" on the Letter of Transmittal or   
        
(ii) 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      
     
payment is to be made to, or certificates for unpurchased Shares are to    
       
be issued or returned to, a person other than the registered holder,       
    
then the tendered certificates must be endorsed or accompanied by          
 
appropriate stock powers, 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 by an Eligible   
        
Institution as provided in the Letter of Transmittal.  See Instructions    
       
1 and 5 of the Letter of Transmittal.            
            
     If the certificates representing Shares are forwarded separately      
     
to the Depositary, a properly completed and duly executed Letter of        
    
Transmittal (or facsimile thereof) must accompany each such delivery.      
     
            
     If a Stockholder desires to tender Shares pursuant to the Offer       
    
and cannot deliver such Shares and all other required documents to the     
       
Depositary by the Expiration Date, or such Stockholder cannot complete     
      
the procedure for delivery by book-entry transfer on a timely basis,       
    
such Shares may nevertheless be tendered if all of the following           

conditions are met:            
            
            (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 Merger          
  
Subsidiary, is received by the Depositary (as provided below) by the       
     
Expiration Date; and            
            
           (iii)    the certificates for all physically delivered Shares   

(or a Book-Entry Confirmation of all Shares delivered             
electronically), as well as a properly completed and duly executed         
   
Letter of Transmittal (or facsimile thereof) (or, in the case of a         
   
book-entry transfer, an Agent's Message) and any other documents           
 
required by the Letter of Transmittal, are received by the Depositary      
      
within three trading days on the American Stock Exchange, Inc. (the        
    
"AMEX") after the date of execution of the Notice of Guaranteed            

Delivery.            
            
The Notice of Guaranteed Delivery may be delivered by hand or            
transmitted by facsimile transmission or mail to the Depositary and must   
        
include a guarantee by an Eligible Institution in the form set forth in    
       
such Notice.            
           
<PAGE> 8           
            
      The method of delivery of Shares and all other required documents,   
         
including delivery through any Book-Entry Transfer Facility, is at the     
       
option and risk of the tendering Stockholder, and the delivery will be     
       
deemed made only when actually received by the Depositary.  If            
certificates for Shares are sent by mail, registered mail with return      
     
receipt requested, properly insured, is recommended.  In all cases,        
   
sufficient time should be allowed to ensure timely delivery.            
            
      In all cases, payment for Shares tendered and accepted for payment   
         
pursuant to the Offer will be made only after timely receipt by the        
    
Depositary of the certificates for such Shares, or a Book-Entry            

Confirmation of the delivery of such Shares, and the Letter of            
Transmittal (or a facsimile thereof), properly completed and duly          
 
executed, with any required signature guarantees (or, in the case of a     
      
book-entry transfer, an Agent's Message), and any other documents          
 
required by the Letter of Transmittal.            
            
      Under the federal income tax laws, the Depositary will be required   
        
to withhold 31% of the amount of any payments made to certain            
Stockholders pursuant to the Offer.  In order to avoid such backup         
  
withholding, each tendering Stockholder must provide the Depositary with   
        
such Stockholder's correct taxpayer identification number and certify      
     
that such Stockholder is not subject to such backup withholding by         
  
completing the Substitute Form W-9 included in the Letter of            
Transmittal.              
            
      By executing a Letter of Transmittal, a tendering Stockholder        
    
irrevocably appoints designees of Merger Subsidiary as such            
Stockholder's proxies in the manner set forth in the Letter of            
Transmittal to the full extent of such Stockholder's rights with respect   
        
to the Shares tendered by such Stockholder and accepted for payment by     
      
Merger Subsidiary (and any and all other Shares or other securities        
   
issued or issuable in respect of such Shares on or after October 7,        
   
1996).  All such proxies shall be considered coupled with an interest in   
        
the tendered Shares.  Such appointment is effective only upon the          
 
acceptance for payment of such Shares by Merger Subsidiary.  Upon such     
      
acceptance for payment, all prior proxies and consents granted by such     
      
Stockholder with respect to such Shares and other securities will,         
  
without further action, be revoked, and no subsequent proxies may be       
    
given nor subsequent written consents executed by such Stockholder (and,   
        
if given or executed, will not be deemed to be effective).  Such           

designees of Merger Subsidiary will be empowered to exercise all voting    
       
and other rights of such Stockholder as they, in their sole discretion,    
       
may deem proper at any annual, special or adjourned meeting of the         
  
Company's stockholders, by written consent or otherwise. Merger            
Subsidiary reserves the right to require that, in order for Shares         
   
to be validly tendered, immediately upon Merger Subsidiary's acceptance    
       
for payment of such Shares, Merger Subsidiary is able to exercise full     
      
voting rights with respect to such Shares and other securities            
(including voting at any meeting of stockholders then scheduled or         
  
acting by written consent without a meeting).            
            
       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 will be determined by Merger Subsidiary, in its       
    
sole discretion, which determination shall be final and binding on all     
      
parties.  Merger Subsidiary reserves the absolute right to reject any or   
        
all tenders of Shares determined by it not to be in proper form or the     
      
acceptance for payment of or payment for which may, in the opinion of      
     
Merger Subsidiary's counsel, be unlawful.  Merger Subsidiary also          
 
reserves the absolute right to waive any defect or irregularity in any     
      
tender of Shares, whether or not similar defects or irregularities are     
      
           
<PAGE> 9           
           
waived in the case of any other tender of Shares.  None of Merger          
 
Subsidiary, Computer Associates, the Depositary, the Information Agent     
      
or any other person will be under any duty to give notification of any     
      
defect or irregularity in tenders or incur any liability for failure to    
       
give any such notification.  Merger Subsidiary's interpretation of the     
      
terms and conditions of the Offer (including the Letter of Transmittal     
      
and the instructions thereto) will be final and binding.            
            
     The acceptance for payment of Shares tendered pursuant to any one     
      
of the procedures described above will constitute an agreement between     
      
the tendering Stockholder and Merger Subsidiary upon the terms and         
  
subject to the conditions of the Offer.            
            
4.   Withdrawal Rights.             
            
     Tenders of Shares made pursuant to the Offer may be withdrawn at      
     
any time prior to the Expiration Date.  Thereafter, such tenders are       
     
irrevocable, except that they may be withdrawn on or after December 9,     
      
1996 unless theretofore accepted for payment as provided in this Offer     
      
to Purchase.  If Merger Subsidiary extends the period of time during       
    
which the Offer is open, is delayed in accepting for payment or paying     
      
for Shares or is unable to accept for payment or pay for Shares pursuant   
        
to the Offer for any reason, then, without prejudice to Merger            
Subsidiary's rights under the Offer, the Depositary may, on behalf of      
     
Merger Subsidiary, retain all Shares tendered, and such Shares may not     
      
be withdrawn except as otherwise provided in this Section 4.            
            
      For a withdrawal to be effective, a written 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 and must specify the name of the person who tendered     
      
the Shares to be withdrawn and the number of Shares to be withdrawn.  If   
        
the Shares to be withdrawn have been delivered to the Depositary, a        
   
signed notice of withdrawal with (except in the case of Shares tendered    
       
by an Eligible Institution) signatures guaranteed by an Eligible           

Institution must be submitted prior to the release of such Shares.  In     
      
addition, such notice must specify, in the case of Shares tendered by      
     
delivery of certificates, the name of the registered holder (if            
different from that of the tendering Stockholder) and the serial numbers   
        
shown on the particular certificates evidencing the Shares to be           

withdrawn or, in the case of Shares tendered by book-entry             
transfer, the name and number of the account at one of the Book-Entry      
      
Transfer Facilities to be credited with the withdrawn Shares.             
Withdrawals may not be rescinded, and Shares withdrawn will thereafter     
      
be deemed not validly tendered for purposes of the Offer.  However,        
   
withdrawn Shares may be retendered by again following one of the           

procedures described in Section 3 at any time prior to the Expiration      
     
Date.           
            
      All questions as to the form and validity (including time of         
  
receipt) of any notice of withdrawal will be determined by Merger          
 
Subsidiary, in its sole discretion, which determination shall be final     
      
and binding.  None of Merger Subsidiary, Computer Associates, the          
 
Depositary, the Information Agent or any other person will be under any    
       
duty to give notification of any defect or irregularity in any notice of   
        
withdrawal or incur any liability for failure to give any such            
notification.

5.   Certain Tax Consequences.             
            
     This summary sets forth material anticipated Federal income tax       
     
consequences to Stockholders of their disposition of Shares pursuant to    
  
the Offer and the Merger.  The summary is based on the provisions of the   
 
Internal Revenue Code of 1986, as amended (the "Code"), the Treasury       
     
regulations promulgated thereunder, and administrative and judicial        
    
interpretations thereof, all as currently in effect.  Such laws or         
   
interpretations may differ on the date of the consummation of the Offer    
       
or at the Effective Time, and relevant facts may also differ.  The         
  
summary does not address any foreign, state or local tax consequences,     
      
nor does it address estate or gift tax considerations.  Neither the        
   
consummation of the Offer nor the effectiveness of the Merger is           

conditioned upon the receipt of any ruling from the Internal Revenue       
    
Service or any opinion of counsel as to tax matters.            
            
     This summary is for general information only.  The tax treatment      
     
of each Stockholder will depend in part upon his particular situation.     
Special tax consequences not described below may be applicable to          
  
particular classes of taxpayers, including financial institutions,         
  
pension funds, mutual funds, broker-dealers, persons who are not           

citizens or residents of the United States or who are foreign            
corporations, foreign partnerships or foreign estates or trusts,           

Stockholders who own actually or constructively (under certain            
attribution rules contained in the Code) 5% or more of the Shares,         
  
Stockholders who acquired their Shares through the exercise of an          
 
employee stock option or otherwise as compensation, and persons who        
   
receive payments in respect of options to acquire Shares.  All             
Stockholders should consult with their own tax advisers as to the          
  
particular tax consequences of the Offer and the Merger to them,           

including the applicability and effect of any state, local and foreign     
      
tax laws.            
            
      Sales of Shares by Stockholders pursuant to the Offer (or the        
   
Merger)  will be taxable transactions for Federal income tax purposes      
     
and may also be taxable transactions under applicable state, local,        
   
foreign and other tax laws.            
            
      In general, a Stockholder will recognize gain or loss equal to the   
  
difference between the tax basis of such Stockholder's Shares and the      
      
amount of cash received in exchange for the Shares.  This gain or loss     
      
will be capital gain or loss if the Shares are capital assets in the       
    
hands of the Stockholder and will be long-term capital gain or loss if     
      
the holding period for the Shares is more than 12 months as of the date    
       
of the sale of such Shares.

aggregate of $700 million of loans, in each case on an unsecured basis     
     
          
<PAGE> 16          
          
and at interest rates (at Computer Associates' option)             
of (i) the London inter bank offered rate plus a margin of .070% (as       
     
adjusted from time to time based upon the financial performance of         
   
Computer Associates) or (ii) the higher of (x) the Credit Suisse base      
      
lending rate and (y) the federal funds rate plus a margin of 0.50%.        
    
Loans under the Credit Agreements are repayable (with a right to borrow)   
       
on the last of each interest period applicable thereto, with full and      
    
final repayment due, in the case of the $1.3 Billion Credit Agreement,     
     
on July 2, 2001 and, in the case of the $700 Million Credit Agreement,     
     
on July 9, 1997 (unless, in the case of the $700 Million Credit           
Agreement, extended pursuant to annual evergreen provisions by mutual      
    
agreement between Computer Associates and the Banks).  The Credit          

Agreements include customary covenants by Computer Associates, including   
       
financial covenants.            
            
      As of October 8, 1996, Computer Associates had (i) approximately     
       
$200 million in cash, cash equivalents and marketable securities and       
    
(ii) availability to borrow up to an additional $1.13 billion of loans     
     
under the Credit Agreements.            
            
      The foregoing summary of the source and amount of funds is           

qualified in its entirety by reference to the text of the Credit           
Agreements, copies of which are filed as exhibits to Computer           
Associates' Quarterly Report on Form 10-Q for the three months ended       
   
June 30, 1996 filed with the Commission and are incorporated in this       
   
Offer to Purchase by reference and may be inspected in the same manner     
     
as set forth with respect to the Company in Section 7.            
            
      Although no definitive plan or arrangement for repayment of          
  
borrowings under the Credit Agreements have been made, Computer            
Associates anticipates such borrowings will be repaid with internally      
    
generated funds (including, if the Merger is accomplished, those of the    
      
Company) and from other sources which may include the proceeds of future   
       
bank refinancings or the public or private sale of debt or equity          

securities.  No decision has been made concerning the method Computer      
    
Associates will use to repay the borrowings under the Credit Agreements.   
        
Such decision will be made based on Computer Associates' review from       
   
time to time of the advisability of particular actions, as well as         
 
prevailing interest rates, financial and other economic conditions and     
     
such other factors as Computer Associates may deem appropriate.            
            
10.    Background of the Offer; Past Contacts, Transactions or            
Negotiations with the Company.            
            
       Computer Associates and the Company have various licensing and      
      
development arrangements pursuant to which the Company develops software   
         
to be compatible with certain Computer Associates products, Computer       
     
Associates licenses Company products to sell as part of Computer           
 
Associates product offerings and the Company licenses to sell Computer     
       
Associates products that include Company software.  Representatives of     
       
Computer Associates and the Company have met from time to time over the    
        
past several years to discuss the technical and marketing aspects of       
    
these  arrangements.  As part of those discussions, Charles B. Wang,       
   
Chairman and  Chief Executive Officer of Computer Associates, Sanjay       
   
Kumar, President and Chief Operating Officer of Computer Associates, and   
       
ReiJane Huai,  Chairman and Chief Executive Officer of the Company, have   
       
met to discuss the existing relationships, synergies of the companies      
    
and ways of expanding the existing relationships.            
          
<PAGE> 17          
            
      During May 1996, Mr. Wang and Mr. Kumar discussed with Mr. Huai      
     
the synergies that might result from developing a closer relationship      
     
between the two companies.  On June 2, Mr. Huai and Elliot Levine, Chief   
        
Financial Officer of the Company, met at Mr. Kumar s home with Mr. Wang,   
       
Mr. Kumar and Charles P. McWade, Senior Vice President of Computer         
 
Associates, to discuss the synergies of a possible stock-for-stock         
 
business combination in which the Company s shareholders would receive     
     
shares of Computer Associates common stock.            
            
      Shortly thereafter, Computer Associates and the Company, together    
        
with their respective counsel, discussed entering into a confidentiality   
         
agreement to permit each party to engage in a due diligence review of      
     
the other party.  Mr. Kumar had several discussions with Mr. Huai over     
     
the terms of the confidentiality agreement.  Before coming to agreement    
      
on the terms of the confidentiality agreement, the Company and Computer    
        
Associates ceased discussions.            
            
      Mr. Kumar had further discussions with Mr. Huai in early July and    
        
again in early August about the possibility of beginning due diligence     
      
and discussing terms of a business combination.  At the August meeting     
     
of the Computer Associates Board of Directors, Mr. Kumar discussed         
 
several strategic options for Computer Associates, including a possible    
      
business combination with the Company.            
            
      On August 7, 1996, representatives of the parties met, at the        
    
initiation of Computer Associates, and discussed the possibility of a      
      
stock-for-stock transaction.  No understanding was reached with respect    
       
to the basic financial terms.  Accordingly, the parties determined not     
     
to enter into a confidentiality agreement, exchange information or         
 
engage in further discussions at that time.            
            
      On September 27, Mr. Huai was meeting with Mr. Wang on unrelated     
       
business, when the possibility of a combination was again raised.  Later   
         
that day, Mr. Kumar asked Mr. Huai for a meeting with him and             
representatives of Lazard, Freres & Co. LLC, financial advisors to the     
       
Company, to discuss the steps required to be taken toward discussing a     
       
possible business combination with the Company.  On the morning of         
   
September 29, Mr. Kumar met with the Lazard representatives to discuss a   
         
possible transaction between Computer Associates and the Company.  Later   
         
that day, Mr. Kumar discussed the possibility of a transaction with Mr.    
        
Huai, and agreed to discuss entering into a confidentiality agreement      
     
and  the process to complete a transaction.            
            
      On the morning of October 1, Mr. Kumar and Mr. McWade met with Mr.   
         
Huai and the Lazard representatives to discuss the next steps in           

exploring a possible business combination.  Later that day, Computer       
   
Associates and the Company entered into a confidentiality agreement, and   
       
Computer Associates began a due diligence review of the Company.           

            
     Between October 1 and October 5, Computer Associates and the          
  
Company, and their legal and financial advisors, discussed the terms of    
       
a merger agreement.  During that time, Computer Associates conducted its   
        
due diligence review in New York City and on Long Island, and Mr. Kumar    
      
had several long and detailed discussions with Mr. Huai on strategic       
   
issues, management and operations and retention of the Company s           
employees.  On October 4, Mr. Kumar presented the transaction to the       
   
Computer Associates Board as an all cash transaction in a range of         
 
values that Computer Associates believed would be appropriate to           
complete a business combination with the Company.  The Board unanimously   
       
          
<PAGE> 18          
          
approved the transaction and authorized Mr. Kumar to proceed to           
negotiate a merger agreement, subject to due diligence and final           
valuation.            
            
     On the morning of October 6, Mr. Kumar met with Mr. Huai, together    
        
with each of their legal advisors and representatives of Lazard, to        
    
discuss certain terms of the merger agreement and valuation.  After        
    
reaching an impasse, with Computer Associates offering a price of $30.30   
         
per Share and the Company seeking a higher price, Computer Associates      
      
delivered a letter to Mr. Huai and the Company s Board proposing that      
      
Computer Associates would acquire the Company in a transaction in which    
        
the Company s shareholders would receive $28.50 per share in cash.  In     
      
the late afternoon of October 6, the Company s legal counsel advised       
    
Computer Associates that the Company s Board had considered the proposal   
       
and rejected it.            
            
      Later in the evening, Mr. Kumar held discussions with             
representatives of Lazard and with Mr. Huai on the outstanding issues in   
         
the merger agreement, including valuation.  Following those discussions,   
         
Mr. Kumar sent a second letter to Mr. Huai offering to enter into a        
   
merger transaction with the Company in which its shareholders would        
  
receive $30.30 per share in cash.  In that letter, Mr. Kumar stated:       
    
            
            This letter will confirm Computer Associates International,    
        
Inc. s offer to enter into a transaction in which Cheyenne s             
stockholders would receive in cash $30.30 per share.  We only want         
   
to pursue this offer with the full support of your Board of             
Directors as well as your management.            
                 
            As we have discussed in detail during the past week,a merger   
         
of our companies would involve no fundamental changes in Cheyenne,         
   
its business relationships, its management or its employees.  We           
 
respect what the management team and you have achieved.  Together we       
     
can create a combined enterprise that will offer greater             
opportunities for your employees and a broader range of products for       
     
your customers.  Importantly, our plans are premised on all of             
Cheyenne s employees continuing with the combined company.  Because        
    
of our close geographic location, we see a great opportunity for           
 
continuity.  We also believe that CA s financial strength, industry        
    
leadership, strong customer base and technological expertise can add       
     
tremendous value for Cheyenne s growth and expansion.            
                 
            As you know, as of this morning we were in substantial         
   
agreement with respect to the terms and conditions of our proposed         
   
merger agreement.  The transaction would be subject, among other           
 
things, to the receipt of regulatory approvals and third-party             
consents as well as the completion of all necessary actions to             
eliminate the applicability of, or to satisfy, any anti-takeover or        
    
other defensive provisions contained in the corporate statutes or          
  
your company s charter and by-laws.  I have discussed our interest         
   
with members of our senior management team and our Board of             
Directors, all of whom share my enthusiasm for this transaction.           

                 
            We are willing to discuss any aspect of the merger with the    
        
Board and its advisors tonight.  In the absence of your Board s approval   

tonight, we plan to announce prior to the open of the stock             
market tomorrow that we made the offer and it was not accepted.  We        
    
would prefer to present our offer to your stockholders as the joint        
    
effort of Computer Associates and Cheyenne Software s Board of             
Directors and management.            
          
<PAGE> 19          
            
      Later that night, Mr. Kumar had discussions with Mr. Huai on the     
       
outstanding issues in the merger agreement and the strategic value of a    
        
business combination. Mr. Kumar also had discussions with           
representatives of Lazard about the terms of transaction, timing and       
   
valuation.            
            
      Shortly after midnight on October 7, in a meeting with Mr. Huai      
     
and Mr. Levine, Computer Associates increased its offer to $30.50 per      
    
share and came to agreement over the other remaining issues in the         
 
merger agreement.  Computer Associates was later advised that the          

Company s Board had unanimously approved the offer.  Representatives of    
      
the Company and Computer Associates, their legal counsel and           
representatives of Lazard then met to complete the merger agreement,       
   
which was signed shortly before the opening of the New York and American   
       
Stock Exchanges on October 7.            
            
11.   Purpose of the Offer; Merger Agreement; Appraisal Rights.            
            
      The purpose of the Offer is to acquire control of, and the entire    
        
equity interest in, the Company. Following the Offer, Computer           
Associates and Merger Subsidiary intend to acquire any remaining equity    
      
interest in the Company not acquired in the Offer by consummating the      
    
Merger.            
            
      The Merger Agreement.  The following description of the Merger       
     
Agreement is qualified in its entirety by reference to the text of such    
        
agreement, a copy of which is attached as an exhibit to the Schedule       
    
14D-1 of Merger Subsidiary and Computer Associates filed with the          

Commission in connection with the Offer (the "Schedule 14D-1") and is      
    
incorporated in this Offer to Purchase by reference and may be inspected   
       
in the same manner as set forth with respect to the Company in Section     
     
7.            
            
     The Offer.  The Merger Agreement provides for the making of the       
     
Offer.  The obligation of Merger Subsidiary to accept for payment or pay   
  
for Shares is subject to the satisfaction of the Minimum Condition and     

certain other conditions that are described in Section 15 hereof.          
   
Pursuant to the Merger Agreement, Computer Associates and Merger           
 
Subsidiary expressly reserve the right to waive the conditions to the      
 
Offer and to make any change in the terms or conditions of the Offer;      
      
provided that, without the written consent of the Company, no change may   
         
be made which changes the form of consideration to be paid, decreases      
     
the price per Share or the number of Shares being sought in the Offer,     
      
imposes conditions to the Offer in addition to those set forth in the      
    
Merger Agreement, changes or waives the Minimum Condition, extends the     
     
Offer (except as set forth in the Merger Agreement), or makes any other    
      
change to any condition to the Offer set forth in the Merger Agreement     
     
which is adverse to the holders of Shares.            
            
      In addition, subject to Computer Associates' or the Company's        
    
ability to terminate the Merger Agreement under certain circumstances,     
      
if the applicable waiting period under the HSR Act shall not have          

expired or been terminated as of the date the Offer would otherwise have   
       
expired, Merger Subsidiary has agreed, pursuant to the Merger Agreement,   
       
to extend the Offer from time to time until the earlier of (x) the date    
      
that is 30 days after the first scheduled Expiration Date and (y) the      
    
date that such waiting period has expired or been terminated.            
            
      Consideration to be Paid in the Merger.  The Merger Agreement        
    
provides that, following the purchase of Shares pursuant to the Offer      
     
and upon the terms (but subject to the conditions) set forth in the        
  
          
<PAGE> 20          
          
Merger Agreement, Merger Subsidiary will be merged with and into the       
   
Company (the "Merger"), with the Company continuing as the surviving       
   
corporation (the "Surviving Corporation").  In the Merger, each           
outstanding Share not held by Computer Associates, Merger Subsidiary or    
      
any subsidiary of either of them or by the Company as treasury stock       
   
(and other than Shares as to which appraisal rights have been exercised    
      
pursuant to Section 262 of the Delaware Law ("Dissenting Shares")) will    
      
be converted into the right to receive $30.50 in cash or any higher        
  
price paid for each Share in the Offer, without interest.  Each share of   
       
common stock of Merger Subsidiary issued and outstanding immediately       
   
prior to the time of the Merger will be converted into and become one      
    
share of common stock of the Surviving Corporation, which will thereupon   
       
become a wholly owned subsidiary of Computer Associates.  The Merger       
   
Agreement provides that (i) the closing of the Merger shall take place,    
      
after consummation of the Offer, on the later of (a) November 30, 1996,    
      
provided that as of such date the conditions to the Merger set forth in    
      
the Merger Agreement shall be fulfilled or waived and (b) the first        
  
business day on which all of the conditions to the Merger set forth in     
     
the Merger Agreement shall be fulfilled or waived and (ii) as soon as      
    
practicable following the closing of the Merger, the Company and Merger    
      
Subsidiary will file a certificate of merger with the Secretary of State   
       
of the State of Delaware and make all other filings or recordings          

required by Delaware Law in connection with the Merger.  The Merger        
  
shall become effective at such time as the certificate of merger is duly   
       
filed with the Secretary of State of the State of Delaware or, with the    
      
consent of the Independent Director referred to below, at such later       
   
time as is specified in the certificate of merger (the "Effective          

Time").            
            
       Board Representation.  The Merger Agreement provides that,          
 
effective upon acceptance for payment by Merger Subsidiary of such         
 
number of Shares which satisfies the Minimum Condition, Computer           
Associates shall be entitled to designate the number of directors,         
 
rounded up to the nearest whole number, on the Company's Board of          

Directors that equals the product of (i) the total number of directors     
     
on the Company's Board of Directors and (ii) the percentage that the       
   
number of Shares owned by Computer Associates or Merger Subsidiary         
 
(including Shares accepted for payment) bears to the total number of       
   
Shares outstanding.  The Company has agreed that it will take all action   
       
necessary to cause Computer Associates' designees to be elected or         
 
appointed to the Company's Board of Directors, including increasing the    
      
number of directors or seeking and accepting resignations of incumbent     
     
directors or both; provided that, prior to the Effective Time, the         
 
Company's Board of Directors shall always have one member who is neither   
       
a designee nor an affiliate of Computer Associates or Merger Subsidiary    
      
nor an employee of the Company (an "Independent Director").  No action     
     
proposed to be taken by the Company to amend or terminate the Merger       
   
Agreement or waive any action by Computer Associates or Merger           
Subsidiary shall be effective without the approval of the             
Independent Director.            
            
      The Merger Agreement provides that, from and after the Effective     
       
Time, the directors and officers of Merger Subsidiary at the Effective     
       
Time will be the initial directors and officers of the Surviving           
 
Corporation, each to hold office until his or her respective successors    
  
are duly elected and qualified.  Pursuant to the Merger Agreement, the     
       
Certificate of Incorporation (except for a change in the name of the       
     
corporation) and the By-Laws of Merger Subsidiary, as in effect            

immediately prior to the Effective Time, will be the Certificate of        
    
Incorporation and By-Laws of the Surviving Corporation.           
          
<PAGE> 21          
            
      Stockholder Meeting.  The Merger Agreement provides that, if         
   
required by applicable law, the Company will call a meeting of its         
   
Stockholders to be held as soon as reasonably practicable for the          
 
purpose of voting on the approval and adoption of the Merger Agreement

its subsidiaries, and to furnish Computer Associates and its             
representatives with such other information concerning its business,       
     
properties and personnel as such persons may reasonably request.           

            
      Pursuant to the Merger Agreement, each of Computer Associates and    
        
the Company has agreed to (i) promptly make or cause to be made the        
    
filings required of such party or any of its subsidiaries under the HSR    
        
Act with respect to the transactions contemplated by the Merger            
Agreement,  (ii) comply at the earliest practicable date with any          

request under the HSR Act for additional information, documents, or        
  
other material received by such party or any of its subsidiaries from      
    
any Governmental Entity (defined below in this Section) in respect of      
    
such filings or such transactions, and (iii) cooperate with the other      
    
party in connection with any such filing and in connection with           
resolving any investigation or other inquiry of any such agency or other   
       
Governmental Entity under any Antitrust Laws (defined below in this        
  
Section) with respect to any such filing or any such transaction.  Each    
      
of Computer Associates and the Company has agreed, pursuant to the         
 
Merger Agreement, to promptly inform the other of any communication        
  
with, and any proposed understanding, undertaking, or agreement with,      
    
any Governmental Entity regarding any such filings or any such           
transaction.  The Merger Agreement prohibits both Computer Associates      
    
and the Company from participating in any meeting with any Governmental

other inquiry without giving the other notice of the meeting and, to the   
         
extent permitted by such Governmental Entity, the opportunity to attend    
        
and participate.            
            
       Each of Computer Associates and the Company has agreed, pursuant    
       
to  the Merger Agreement, to use all reasonable efforts to resolve such

respect to the transactions contemplated by the Merger Agreement under     
      
the HSR Act, the Sherman Act, as amended, the Clayton Act, as amended,     
     
the Federal Trade Commission Act, as amended, and any other Federal,       
   
state or foreign statutes, rules, regulations, orders or decrees that      
    
are designed to prohibit, restrict or regulate actions having the          

purpose or effect of  monopolization or restraint of trade           
(collectively, "Antitrust Laws"). In connection therewith, if any          

administrative or judicial action or proceeding is instituted (or          

threatened to be instituted) challenging any transaction contemplated by   
       
the Merger Agreement as violative of any  Antitrust Law, and, if by        
  
mutual agreement, Computer Associates and the Company decide that          

litigation is in their best interests, each of Computer Associates and     
     
the Company have agreed, pursuant to the Merger Agreement, to cooperate    
      
and use all reasonable efforts vigorously to  contest and resist any       
   
such action or proceeding and to have vacated, lifted, reversed, or        
  
overturned any decree, judgment, injunction or other             
order, whether temporary, preliminary or permanent (each an "Order"),      
     
that  is in effect and that prohibits, prevents, or restricts           
consummation of the Merger or any such other transactions.  Pursuant to    
      
the Merger  Agreement, each of Computer Associates and the Company have    
      
agreed to use all reasonable efforts to take such action as may be         
 
required to cause the expiration of the notice periods under the HSR Act   
       
or other Antitrust Laws with respect to such transactions as promptly as   
       
possible after the  execution of the Merger Agreement.              
          
<PAGE> 24          
            
       Subject to the fiduciary duties of the Board of Directors of the    
        
Company as advised in writing by counsel to the Company, each of           

Computer Associates and the Company has agreed, pursuant to the Merger     
     
Agreement, to use all reasonable efforts to take, or cause to be taken,    
      
all actions, and to do, or cause to be done, and to assist and cooperate   
       
with the other parties in doing, all things necessary, proper or           
advisable to consummate and make effective, in the most expeditious        
  
manner practicable, the Offer, the Merger, and the other transactions      
    
contemplated by the Merger  Agreement.            
            
       Notwithstanding the foregoing, the Merger Agreement provides that   
         
(i) neither Computer Associates nor any of its subsidiaries shall be       
     
required to divest any of their respective businesses, product lines or    
        
assets, (ii) neither Computer Associates nor any of its subsidiaries       
    
shall be required to take or agree to take any other action or agree to    
      
any limitation that could reasonably be expected to have a material        
  
adverse effect on the business, assets, financial condition, results of    
       
operations  or prospects of Computer Associates and its subsidiaries       
   
taken as a whole or of Computer Associates combined with the Surviving     
     
Corporation after the Effective Time, (iii) neither the Company nor its    
      
subsidiaries shall be required to divest any of their respective           
businesses, product lines or assets, or to take or agree to take any       
   
other action or agree to any limitation that could reasonably be           
expected to have a Material Adverse Effect (defined below in Section       
   
15), (iv) no party shall be required to agree to the imposition of, or     
     
to comply with, any condition, obligation or restriction on Computer       
   
Associates or any of its subsidiaries or on the  Surviving Corporation     
     
or any of its subsidiaries of the type described in clause (a) or (b) of   
       
Section 15 and (v) neither Computer Associates nor  Merger Subsidiary      
    
shall be required to waive any of the conditions to the Offer described    
      
in Section 15 or any of the conditions to the Merger described in this     
     
Section 11.            
            
       Agreements with respect to Employee Matters.  Computer Associates   
         
has agreed in the Merger Agreement to honor in accordance with their       
    
terms  all of the Company's employee benefit plans (including employment   
         
agreements) previously delivered to Computer Associates and all accrued    
        
benefits vested thereunder; provided that nothing in the Merger            
Agreement shall prevent Computer Associates from terminating any such      
    
benefit plan in accordance with its terms.  Computer Associates has also   
       
agreed to  provide employees of the Company and its subsidiaries           
retained by Computer Associates with employee benefits in the aggregate    
      
no less favorable than those benefits provided to Computer Associates'     
     
similarly situated employees; provided that Computer Associates shall be   
       
under no obligation to retain any employee or group of employees of the    
      
Company or its  subsidiaries.            
            
       Pursuant to the Merger Agreement, at the Effective Time, each of    
       
the then outstanding Company Options (defined below) shall by virtue of    
      
the Merger, and without any further action on the part of any holder       
    
thereof, become fully exercisable and vested and be assumed by Computer    
       
Associates  and converted into an option to purchase that number of        
  
shares of common stock, par value $.10 per share ("Computer Associates     
     
Common Stock"), of Computer Associates determined by multiplying the       
   
number of Shares subject to such Company Option at the Effective Time by   
       
the quotient obtained by  dividing (x) $30.50 by (y) the average closing   
       
price of Computer Associates Common Stock on the New York Stock Exchange   
       
Composite Tape for the 20 consecutive trading days immediately prior to    
      
the Effective Time (such quotient, the "Conversion Number"), at an         
 
exercise price per share of Computer Associates Common Stock equal to      
    
the quotient obtained by dividing (x) the exercise price per Share of      
    
          
<PAGE> 25          
          
such Company Option  immediately prior to the Effective Time by (y) the    
      
Conversion Number.  If the foregoing calculation results in an assumed     
     
Company Option being  exercisable for a fraction of a share of Computer    
      
Associates Common Stock, then the number of shares of Computer           
Associates Common Stock subject to such option shall be rounded down to    
      
the nearest whole number of shares. Except as otherwise set forth in the   
       
Merger  Agreement, the term, status as an "incentive stock option" under   
       
Section 422 of the Code, if  applicable, and all other terms and           
conditions of Company Options will, to the extent permitted by law and     
     
otherwise reasonably practicable, be  unchanged.  Pursuant to the Merger   
       
Agreement, the Company agreed to take, or cause to be taken, all actions   
       
which are necessary, proper or advisable under the Stock Plans (defined    
      
below) to make effective the transactions  described in this paragraph.    
       
"Company Options" means any option granted, and not exercised or           
expired, to a current or former employee, director or independent          

contractor of the Company or any of its subsidiaries or any             
predecessor thereof to purchase Shares pursuant to any stock option,       
    
stock  bonus, stock award, or stock purchase plan, program, or           
arrangement of the Company or any of its subsidiaries or any predecessor   
       
thereof  (collectively, the "Stock Plans") or any other contract or        
  
agreement entered into by the Company or any of its subsidiaries.          
 
            
       Pursuant to the Merger Agreement, Computer Associates agreed to     
      
take  all corporate action necessary to reserve for issuance a           
sufficient number of shares of Computer Associates Common Stock for        
  
delivery pursuant to the  terms described in the immediately preceding     
     
paragraph.  Pursuant to the Merger Agreement, Computer Associates agreed   
       
to cause the shares of  Computer Associates Common Stock issuable upon     
     
exercise of the assumed Company Options to be registered, or to be         
 
issued pursuant to a then effective registration statement, no later       
   
than 90 days after the  Effective Time on Form S-8 promulgated by the      
    
Commission, and to use its  best efforts to maintain the effectiveness     
     
of such registration statement or registration statements for so long as   
       
such assumed Company Options  remain outstanding.  The Merger Agreement    
      
provides that, with respect to  those individuals who subsequent to the    
      
Merger will be subject to the  reporting requirements under Section        
  
16(a) of the Exchange Act, Computer Associates shall administer the        
  
Company Options assumed pursuant to the Merger Agreement in a manner       
   
that complies with Rule 16b-3 promulgated by  the SEC under the Exchange   
       
Act, but shall have no responsibility for such compliance by the Company   
       
or its predecessors.            
            
       Other Offers.  Pursuant to the Merger Agreement, the Company has    
        
agreed that the Company and its subsidiaries will not, and will not        
    
authorize or permit the officers, directors, employees or other agents     
      
of  the Company and its subsidiaries to, directly or indirectly, (i)       
   
take any action to solicit, initiate or encourage any Acquisition          

Proposal (defined below) or (ii) subject to the fiduciary duties of the    
      
Board of Directors under applicable law, as advised in writing by          

counsel to the Company, engage in negotiations with, or disclose any       
   
nonpublic information relating to the Company or any of its subsidiaries   
       
or afford access to the properties, books or records of the Company or     
     
any of its subsidiaries to, any person that has advised the Company or     
     
otherwise publicized the fact that it may be considering making, or that   
       
has made, an Acquisition  Proposal; provided, nothing herein shall         
 
prohibit the Company's Board of Directors from taking and disclosing to    
      
the Company's stockholders a  position with respect to a tender offer      
    
pursuant to Rules 14d-9 and 14e-2 promulgated under the Exchange Act.      
     
The Company has agreed to promptly notify Computer Associates after        
  
receipt of any Acquisition Proposal or any notice that any person is       
   
considering making an Acquisition Proposal or any request for nonpublic    
      
information relating to the Company or any of  its subsidiaries or for     
     
access to the properties, books or records of the Company or any of its    
      
          
<PAGE> 26          
          
subsidiaries by any person that has advised the  Company or otherwise      
    
publicized the fact that it may be considering  making, or that has        
  
made, an Acquisition Proposal and will keep Computer Associates informed   
       
of the status and details of any such Acquisition  Proposal, indication    
      
or request.  "Acquisition Proposal" means any offer or proposal for, or    
      
any written indication of interest in, a merger or  other business         
 
combination involving the Company or any of its  subsidiaries or the       
   
acquisition of any significant equity interest in, or a significant        
  
portion of the assets of, the Company or any of its subsidiaries, other    
      
than the transactions contemplated by the Merger  Agreement.            
            
      Rights Agreement.  In connection with the execution of the Merger    
        
Agreement, the Company amended the Rights Agreement to make it and the     
       
Rights inapplicable to the Offer and the Merger.  The Merger Agreement     
       
provides that, except with respect to amending the Rights Agreement to     
       
make it and the Rights inapplicable to the Offer and the Merger, the       
     
Company shall not redeem the Rights or amend or terminate the Rights       
     
Agreement prior to the Effective Time unless required to do so by a        
   
court  of competent jurisdiction.            
            
      Agreement with respect to Director and Officer Indemnification and   
         
Insurance.  Pursuant to the Merger Agreement, Computer Associates has      
      
agreed, subject to any limitation imposed from time to time under          
  
applicable law, that, for a period of six years after the Effective        
   
Time, it will indemnify and hold harmless the present and former           
officers, directors, employees and agents of the Company in respect of     
     
acts or omissions occurring on or prior to the Effective Time to the       
   
extent provided under the Company's certificate of incorporation and       
   
bylaws in  effect on the date of the Merger Agreement.  Computer           
Associates has further agreed that, for four years after the Effective     
     
Time, it will  cause the Surviving Corporation to provide officers' and    
      
directors'  liability insurance in respect of acts or omissions           
occurring on or prior to the Effective Time covering each such person      
    
currently covered by the  Company's officers' and directors' liability     
     
insurance policy on terms  substantially similar to those of such policy   
       
in effect on the date of the Merger Agreement, provided that in           
satisfying such obligation, Computer Associates is not obligated to        
  
cause the Surviving Corporation to pay  premiums in excess of 105% of      
    
the amount per annum the Company paid in its last full fiscal year, and    
      
if the Surviving Corporation is unable to  obtain such insurance, it       
   
shall obtain as much comparable insurance as  possible for an annual       
   
premium equal to such maximum amount.  Computer Associates has also        
  
agreed that, in the event any such indemnified person  is or becomes       
   
involved in any capacity in any action, proceeding or  investigation in    
      
connection with any matter relating to the Merger, the  Offer or the       
   
Merger Agreement occurring on or prior to the Effective Time,             
it will pay as incurred such indemnified person's reasonable legal and     
       
other expenses (including the cost of any investigation and preparation)   
         
incurred in connection therewith.            
            
      Other Agreements. Computer Associates has agreed that it will take   
         
all action necessary to cause Merger Subsidiary to perform its           
obligations  under the Merger Agreement and to consummate the Offer and    
      
the Merger on the terms and conditions set forth in the Merger           
Agreement.  Computer Associates also agreed, pursuant to the Merger        
  
Agreement, to hold in confidence all confidential information concerning   
       
the Company and its subsidiaries in accordance with the terms of the       
   
Confidentiality  Agreement, dated October 1, 1996, between Computer        
  
Associates and the  Company, a copy of which is filed as an exhibit to     
     
the Schedule 14D-1 and  is incorporated in this Offer to Purchase by       
   
reference.            
          
<PAGE> 27          
            
      Conditions to the Merger.  Pursuant to the Merger Agreement, the

the  Effective Time of the following conditions: (i) Computer Associates   
       
or  Merger Subsidiary shall have purchased Shares in an amount equal to

law or regulation and no judgment, injunction, order or decree shall       
    
prohibit the consummation of the Merger, (iv) any applicable waiting       
   
period under the HSR Act relating to the Merger shall have expired, and    
      
(v) other than filing the certificate of merger in accordance with         
 
Delaware Law, all consents, approvals, orders or authorizations of, or     
     
registrations,  declarations or filings with or exemptions by           
(collectively, "Consents")  any Federal, state or local government or      
    
any court, administrative or regulatory agency or commission or other      
    
governmental authority or agency,  domestic or foreign (a "Governmental    
      
Entity") required to consummate the  Merger shall have been filed,         
 
occurred or been obtained (other than any such Consents the failure to     
     
occur, obtain or file, in the aggregate,  could not reasonably be          

expected to (a) have a Material Adverse Effect  (defined below in          

Section 15) or (b) prevent or materially delay the  consummation of the    
      
Merger).            
            
       Termination.  The Merger Agreement may be terminated at any time    
        
prior to the Effective Time (notwithstanding any approval of the Merger    
        
Agreement by the Stockholders) (i) by mutual written consent of the        
    
Company and Computer Associates, (ii) by either the Company or Computer    
        
Associates, if the Merger has not been consummated by April 7, 1997        
    
(provided that the party seeking to terminate the Merger Agreement shall   
         
not have breached its obligations under the Merger Agreement in any        
    
material respect),(iii)by either the Company or Computer Associates, if    
        
there shall be any law or regulation that makes consummation of the        
  
Merger illegal or otherwise prohibited or if any judgment, injunction,     
     
order or decree enjoining Computer Associates or the Company from          

consummating the Merger is entered and such judgment, injunction, order    
      
or decree shall  become final and nonappealable, (iv) by either the        
  
Company or Computer Associates, (a) if Computer Associates shall have      
    
failed to commence the Offer within five business days following the       
   
date of the Merger Agreement (provided that Computer Associates shall      
    
not be entitled to terminate the  Merger Agreement in the circumstance     
     
described in this sub-clause (a) as a result of its breach of the Merger   
       
Agreement), (b) if Computer Associates or Merger Subsidiary shall not      
    
have purchased any Shares pursuant to the Offer prior to February 21,      
    
1997 or (c) if the Offer shall have been  terminated without Computer      
    
Associates or Merger Subsidiary having  purchased any Shares pursuant to   
       
the Offer, (v) by Computer Associates,  upon the occurrence of any         
 
Trigger Event (defined below), or (vi) by the Company, if the Company      
    
shall have entered into, or shall have publicly  announced its intention   
       
to enter into, an agreement or an agreement in  principle with respect     
     
to any Acquisition Proposal.            
            
       Fees and Expenses. Each party to the Merger Agreement has agreed    
      
to pay its own fees and expenses and there are no provisions for payment   
       
by the Company of the fees and expenses of Computer Associates or Merger   
         
Subsidiary or vice versa, if the Merger Agreement is terminated, except    
       
as stated below.  The Company has agreed to pay Computer Associates a      
    
fee in immediately available funds, promptly, but in no event later than   
       
two business days, after the termination of the Merger Agreement as a      
    
result of the occurrence of any of the events set forth below (a           
"Trigger Event") in an amount equal to (a) $37,500,000, in the case of     
     
          
<PAGE> 28          
          
the occurrence of a  Trigger Event described in clause (i) or (iii)        
  
below and (b) $20,000,000, in the case of the occurrence of a Trigger      
    
Event described in clause (ii) below:  (i) the Company shall have          

entered into, or shall have publicly announced its intention to enter      
    
into, an agreement or an agreement in principle with respect to any        
  
Acquisition Proposal, (ii) the Company shall have breached or failed to    
      
perform in any respect any of its obligations, covenants or agreements     
     
under the Merger Agreement or any representation or warranty of the        
  
Company set forth in the Merger Agreement (other than breaches or          

failures to perform or comply that, in the aggregate, do not have a        
  
Material Adverse Effect), or (iii) the Board of Directors of the Company   
       
(or any special committee thereof) shall have withdrawn or  materially     
     
modified its approval or recommendation of the Offer, the  Merger or the   
       
Merger Agreement.            
            
        The Company has also agreed that, if the Merger Agreement is       
     
terminated as a result of the occurrence of a Trigger Event, it shall      
      
assume and pay, or reimburse Computer Associates for, all fees payable     
      
and  expenses incurred by Computer Associates (including the fees and      
     
expenses of its counsel) in connection with the Merger Agreement and the   
         
transactions contemplated by the Merger Agreement, up to a maximum of      
      
$5,000,000.            
            
       Timing.  The exact timing and details of the Merger will depend     
      
upon  legal requirements and a variety of other factors, including the     
     
number of Shares acquired by Merger Subsidiary pursuant to the Offer.      
     
Although  Computer Associates has agreed to cause the Merger to be         
 
consummated on the terms set forth above, there can be no assurance as     
     
to the timing of the Merger.            
            
        Computer Associates and Merger Subsidiary reserve the right to     
       
acquire additional Shares following the expiration or termination of the   
         
Offer through open market transactions, private purchases, other tender    
        
offers or otherwise, on terms and at prices that may be the same as, or    
        
more or less favorable than, those of the Offer.            
            
      Appraisal Rights. Stockholders do not have dissenters' rights as a   
         
result of the Offer.  However,if the Merger is consummated, Stockholders   
         
of the Company at the time of the Merger who do not vote in favor of or    
        
consent in writing to the Merger will have the right under Delaware Law    
       
to  dissent and demand appraisal of their Shares in accordance with        
  
Section 262 of the Delaware Law.                    
            
      Under Delaware Law, dissenting stockholders who comply with the      
      
applicable statutory procedures will be entitled to receive a judicial     
       
determination of the fair value of their Shares (exclusive of any          
 
element of value arising from the accomplishment or expectation of the     
     
Merger) and to receive payment of such fair value in cash, together with   
       
a fair rate of interest, if any.  Any such judicial determination of the   
       
fair value of  the Shares could be based upon considerations other than    
      
or in addition to  the price paid in the Offer (or the Merger) and the     
     
market value of the Shares.  Stockholders should recognize that the        
  
value so determined could  be higher or lower than the price per Share     
     
paid pursuant to the Offer or the Merger.  Moreover, Computer Associates   
       
or Merger Subsidiary may argue in an appraisal proceeding that, for        
  
purposes of such a proceeding, the  fair value of the Shares is less       
   
than the price paid in the Offer (or the Merger).  The foregoing summary   
       
of the rights of dissenting Stockholders  does not purport to be a         
 
complete statement of procedures to be followed  by Stockholders           
desiring to exercise their dissenters' rights.           
          
<PAGE> 29           
            
      Delaware Law.  In addition, the Merger would have to comply with     
       
other applicable procedural and substantive requirements of Delaware       
    
Law,  including any duties to other stockholders imposed upon a           
controlling or, if applicable, majority stockholder.  Several recent       
   
decisions by the Delaware courts, which may or may not apply to the        
  
Merger, have held that a controlling stockholder of a company involved     
     
in a merger has a  fiduciary duty to other stockholders which requires     
     
that the merger be "entirely fair" to such other stockholders.  In         
 
determining whether a  merger is fair to minority stockholders, Delaware   
       
courts have considered, among other things, the type and amount of the     
     
consideration to be  received by the stockholders and whether there was    
      
fair dealing among the  parties.              
            
       The Company is incorporated under the laws of the State of          
 
Delaware,  which has adopted certain laws regarding business           
combinations.  In  general, Section 203 of Delaware Law prevents an        
  
"interested stockholder" (generally, a stockholder owning 15% or more of   
       
a corporation's  outstanding voting stock or an affiliate or associate     
     
thereof) from  engaging in a "business combination" (defined to include    
      
a merger and  certain other transactions) with a Delaware corporation      
    
for a period of  three years following the time that such stockholder      
    
became an interested  stockholder unless (i) prior to such time the        
  
corporation's board of  directors approved either the business           
combination or the transaction  which resulted in such stockholder         
 
becoming an interested stockholder, (ii) upon consummation of the          

transaction which resulted in such  stockholder becoming an interested     
     
stockholder, the interested stockholder  owned at least 85% of the         
 
corporation's voting stock outstanding at the time the transaction         
 
commenced (excluding shares owned by certain employee             
stock plans and persons who are directors and also officers of the         
   
corporation) or (iii) at or subsequent to such time the business           
 
combination is approved by the corporation's board of directors and        
    
authorized at an annual or special meeting of stockholders, and not by     
       
written consent, by the affirmative vote of at least 66 2/3% of the        
    
outstanding voting stock not owned by the interested stockholder.  The     
       
Board of Directors of the Company has approved the Merger Agreement and    
        
the transactions contemplated thereby, including the Offer and the         
  
Merger,  for purposes of Section 203.  Accordingly, the restrictions of    
      
Section 203  do not apply to the transactions contemplated by this Offer   
       
to Purchase.            
            
       Other Matters.  Any merger or other similar business combination    
        
proposed by Computer Associates would also have to comply with any         
   
applicable Federal law.  In particular, the Commission has adopted Rule    
        
13e-3 under the Exchange Act which is applicable to certain "going         
   
private" transactions.  Computer Associates believes that Rule 13e-3       
    
will  not be applicable to the Merger unless the Merger is consummated     
     
more than one year after termination of the Offer or if an alternative     
     
merger  transaction were to provide for stockholders to receive           
consideration for their Shares in an amount less than the price per        
  
Share paid pursuant to the Offer.  If applicable, Rule 13e-3 would         
 
require, among other things,  that certain financial information           
concerning the Company and certain information relating to the fairness    
      
of the proposed transaction and the  consideration offered to minority     
     
stockholders in such a transaction be  filed with the Commission and       
   
distributed to such stockholders prior to  consummation of the           
transaction.            
          
<PAGE> 30          
            
      If for any reason the Merger is not consummated, Computer            
Associates  and Merger Subsidiary will evaluate their alternatives.        
   
Such alternatives could include purchasing additional Shares in the open   
       
market, in  privately negotiated transactions, in another tender or        
  
exchange offer or  otherwise, or taking no further action to acquire       
   
additional Shares. Any additional purchases of Shares could be at a        
  
price greater or less than the price to be paid for Shares in the Offer    
      
and could be for cash or  other consideration.  Alternatively, Merger      
    
Subsidiary may sell or  otherwise dispose of any or all Shares acquired    
      
pursuant to the Offer or otherwise.  Such transactions may be effected     
     
on terms and at prices then  determined by Computer Associates or Merger   
       
Subsidiary, which may vary  from the price to be paid for Shares in the    
      
Offer.            
            
       In the joint press release issued by Computer Associates and the    
        
Company in connection with the execution of the Merger Agreement, a copy   
         
of which is filed as an exhibit to the Schedule 14D-1 and is            
incorporated herein by reference, Computer Associates stated, among        
  
other things, that  it intended to retain all of the Company's           
employees, and that the Company would operate as a division of Computer    
      
Associates.  Computer Associates  intends to conduct a review of the       
   
Company and its assets, corporate structure, dividend policy,           
capitalization, operations, properties and  policies and to consider,      
    
subject to the terms of the Merger Agreement, what, if any, changes        
  
would be desirable in light of the circumstances then existing, and        
  
reserves the right to take such actions or effect such             
changes as it deems desirable.  Such changes could include changes in      
     
the  Company's business, operations, corporate structure,           
capitalization, Board of Directors, policies or dividend policy.           

            
       Except as otherwise described in this Offer to Purchase, Computer   
         
Associates and Merger Subsidiary have no current plans or proposals that   
         
would relate to, or result in, any extraordinary corporate transaction     
       
involving the Company, 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,    
      
any  material change in the Company's capitalization or dividend policy    
      
or any  other material change in the Company's business, corporate         
 
structure, Board of Directors or management.            
            
12.   Effect of the Offer on the Market for the Shares; Stock            
Quotations; Registration under the Exchange Act.            
            
      The purchase of Shares pursuant to the Offer will reduce the         
  
number  of Shares that might otherwise trade publicly and may reduce the   
       
number of holders of Shares, which could adversely affect the liquidity    
      
and market  value of the remaining Shares held by Stockholders other       
   
than Computer Associates or Merger Subsidiary.  Computer Associates        
  
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.     
        
            
     Depending upon the number of Shares purchased pursuant to the         
  
Offer,  the Shares may no longer meet the standards for continued          

inclusion on the AMEX.  If, as a result of the purchase of Shares          

pursuant to the Offer, the Shares no longer meet the standards for         
 
continued inclusion on the  AMEX, the market for the Shares could be       
   
adversely affected.                
          
<PAGE> 31            
          
     The extent of the public market for the Shares and availability of    
        
quotations therefor would, however, depend upon such factors as the        
   
number  of holders and/or the aggregate market value of the publicly-      
   
held Shares  at such time, the interest in maintaining a market in the     
     
Shares on the  part of securities firms, the possible termination of       
   
registration of the  Shares under the Exchange Act and other factors.      
     
            
     The Shares are currently "margin securities" under the regulations    
        
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 on the collateral of such Shares.  Depending      
     
upon  factors similar to those described above regarding listing and       
   
market quotations, the Shares might no longer constitute "margin           
securities" for the purposes of the Federal Reserve Board's margin         
 
regulations and, therefore, could no longer be used as collateral for      
    
loans made by  brokers.            
            
     The Shares are currently registered under the Exchange Act.  Such     
       
registration may be terminated upon application of the Company to the      
      
Commission if the Shares are not listed on a national securities           

exchange  and there are less than 300 holders of record.  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 of the provisions of the Exchange Act, such as the short-swing     
     
profit recovery provisions of  Section 16(b), the requirement of           
furnishing a proxy or information  statement in connection with           
stockholder action and the related  requirement of an annual report to     
     
stockholders and the requirements of Rule 13e-3 under the Exchange Act     
     
with respect to "going private"  transactions, no longer applicable to     
     
the Shares.  Furthermore,  "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 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 eligible             
for trading on the AMEX.  Merger Subsidiary intends to seek to cause the   
         
Company to terminate registration of the Shares under the Exchange Act     
      
as  soon after consummation of the Offer as the requirements for           
termination  of registration of the Shares are met.                
            
13.   Dividends and Distributions.              
            
     If on or after October 7, 1996, the Company should            
(notwithstanding the fact that the following actions may be prohibited     
     
under the Merger Agreement) (i) split, combine or otherwise change the     
     
Shares or its  capitalization, (ii) acquire or otherwise cause a           
reduction in the number of outstanding Shares or (iii) issue or sell any   
       
additional Shares (other than Shares issued pursuant to and in           
accordance with the terms in effect on October 7, 1996 of employee stock   
       
options outstanding prior to such date), shares of any other class or      
    
series of capital stock, other voting securities or any securities         
 
convertible into, or options, rights, or warrants, conditional or          

otherwise, to acquire, any of the foregoing, then, without prejudice to    
      
Merger Subsidiary's rights under Section 15,  Merger Subsidiary may, in    
      
its sole discretion, make such adjustments in  the purchase price and      
    
other terms of the Offer as it deems appropriate  including the number     
     
or type of securities to be purchased.            
            
     If, on or after October 7, 1996, the Company should            
(notwithstanding  the fact that the following actions are prohibited       
   
under the Merger  Agreement) declare or pay any dividend on the Shares     
     
          
<PAGE> 32          
          
or any distribution  with respect to the Shares (including the issuance    
      
of additional Shares or  other securities or rights to purchase of any     
     
securities) that is payable or distributable to Stockholders of record     
     
on a date prior to the transfer to the name of Merger Subsidiary or its    
      
nominee or transferee on the  Company's stock transfer records of the      
    
Shares purchased pursuant to the Offer, then, without prejudice to         
 
Merger Subsidiary's rights under Section 15, (i) the purchase price per    
      
Share payable by Merger Subsidiary pursuant to the Offer may be reduced    
      
to the extent of any such cash dividend or  distribution and (ii) the      
    
whole of any such non-cash dividend or  distribution to be received by     
     
the tendering Stockholders will (a) be  received and held by the           
tendering Stockholders for the account of Merger Subsidiary and will be    
      
required to be promptly remitted and transferred by  each tendering        
  
Stockholder to the Depositary for the account of Merger  Subsidiary,       
   
accompanied by appropriate documentation of transfer, or (b) at the        
  
direction of Merger Subsidiary, be exercised for the benefit of            

Merger Subsidiary, in which case the proceeds of such exercise will        
    
promptly be remitted to Merger Subsidiary.  Pending such remittance and    
        
subject to applicable law, Merger Subsidiary will be entitled to all       
     
rights and privileges as owner of any such non-cash dividend or            

distribution or proceeds thereof and may withhold the entire purchase      
      
price or deduct from the purchase price the amount or value thereof, as    
        
determined by Merger Subsidiary in its sole discretion.            
            
14.   Extension of Tender Period; Termination; Amendment.             
            
     Merger Subsidiary reserves the right, at any time or from time to     
       
time, in its sole discretion, (i) to extend the period of time during      
      
which the Offer is open if, at the scheduled expiration date of the        
   
Offer  or any extension thereof, any of the conditions to the Offer        
  
shall not have been satisfied, until such time as such conditions are      
    
satisfied or  waived, and for a further period of time as described        
  
below in this  paragraph, in any case by giving oral or written notice     
     
of such extension  to the Depositary and by making a public announcement   
       
of such extension or  (ii) except to the extent otherwise provided in      
    
the Merger Agreement, to  amend the Offer in any respect by making a       
   
public announcement of such  amendment.  There can be no assurance that    
      
Merger Subsidiary will exercise its right to extend or amend the Offer.    
       
Notwithstanding the foregoing,  but subject to Computer Associates' or     
     
the Company's ability to terminate  the Merger Agreement under certain     
     
circumstances (described in Section  11), if the applicable waiting        
  
period under the HSR Act shall not have  expired or been terminated as     
     
of the date the Offer would otherwise have  expired, Merger Subsidiary     
     
has agreed, pursuant to the Merger Agreement, to extend the Offer from     
     
time to time until the earlier of (x) the date  that is 30 days after      
    
the first scheduled Expiration Date and (y) the date  that such waiting    
      
period has expired or been terminated.  Subject to the  terms of the       
   
Offer and the satisfaction (or waiver to the extent permitted             
by the Merger Agreement) of the conditions to the Offer, Merger            
Subsidiary  shall accept for payment all Shares validly tendered and not   
       
withdrawn  pursuant to the Offer as soon as practicable after the          

expiration of the Offer and shall pay for all such Shares promptly after   
       
acceptance;  provided, that Merger Subsidiary may extend the Offer for a   
       
period of time of not more than 20 business days to meet the objective     
     
(which is not a  condition to the Offer) that there shall be validly       
   
tendered prior to the Expiration Date (as so extended) and not withdrawn   
       
a number of Shares,  which, together with Shares then owned by Computer    
      
Associates and Merger Subsidiary, represents at least 90% of the Fully     
     
Diluted Shares.             
            
     If Merger Subsidiary shall decide, in its sole discretion, subject    
        
to the terms of the Merger Agreement, to increase the consideration to     
      
          
<PAGE> 33          
          
be paid for Shares pursuant to the Offer and the Offer is scheduled to     
      
expire at any time before the expiration of a period of 10 business days   
       
from,  and including, the date that notice of such increase is first       
   
published, sent or given in the manner specified below, the Offer will     
     
be extended  until the expiration of such period of 10 business days.      
     
If Merger Subsidiary makes a material change in the terms of the Offer     
     
(other than a  change in price or percentage of securities sought) or in   
       
the information  concerning the Offer, or waives a material condition of   
       
the Offer, Merger Subsidiary will extend the Offer, if required by         
 
applicable law, for a  period sufficient to allow stockholders to          

consider the amended terms of  the Offer.              
            
     Merger Subsidiary also reserves the right, in its sole discretion,    
        
subject to the terms of the Merger Agreement, in the event any of the      
      
conditions specified in Section 15 shall not have been satisfied and so    
        
long as Shares have not theretofore been accepted for payment, to delay    
        
(except as otherwise required by applicable law and the rules of the       
     
Commission including Rule 14e-1) acceptance for payment of or payment      
     
for  Shares or to terminate the Offer and not accept for payment or pay    
      
for  Shares.            
            
     If Merger Subsidiary extends the period of time during which the      
      
Offer is open, is delayed in accepting for payment or paying for Shares    
       
or  is unable to accept for payment or pay for Shares pursuant to the      
    
Offer  for any reason, then, without prejudice to Merger Subsidiary's      
    
rights  under the Offer, the Depositary may, on behalf of Merger           
Subsidiary, retain all Shares tendered, and such Shares may not be         
 
withdrawn except as otherwise provided in Section 4.  The reservation by   
       
Merger Subsidiary of  the right to delay acceptance for payment of or      
    
payment for Shares is subject to applicable law, which requires that       
   
Merger Subsidiary pay the consideration offered or return the Shares       
   
deposited by or on behalf of Stockholders promptly after the termination   
       
or withdrawal of the Offer.            
            
     Any extension, termination or amendment of the Offer will be          
  
followed as promptly as practicable by a public announcement thereof.      
      
In  the case of an extension of the Offer, Merger Subsidiary will make a   
         
public announcement of such extension 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 Merger Subsidiary   
         
may choose to make any public announcement, Merger Subsidiary will have    
       
no  obligation (except as otherwise required by applicable law) to         
 
publish,  advertise or otherwise communicate any such public           
announcement other than  by making a release to the Dow Jones News         
 
Service.            
            
15.   Certain Conditions of the Offer.             
            
     Notwithstanding any other provision of the Offer, Computer            

Associates and Merger Subsidiary shall not be required to accept for       
     
payment or pay for any Shares, and may terminate the Offer, if (i) by      
     
the  expiration of the Offer, the Minimum Condition shall not have been    
        
satisfied, (ii) by the expiration of the Offer, the applicable waiting     
       
period under the HSR Act shall not have expired or been terminated, or     
       
(iii) at any time on or after October 7, 1996 and prior to the            
acceptance  for payment of Shares, any of the following conditions         
 
exist:            
            
(a)   there shall be instituted or pending any action or             
proceeding by any Governmental Entity or by any other person,             
domestic or foreign, before any Governmental Entity or arbitrator,         
   
(i) challenging or seeking to make illegal, to delay materially or         
   
          
<PAGE> 34          
          
otherwise directly or indirectly to restrain or prohibit the making        
    
of the Offer, the acceptance for payment of or payment for some of         
   
or all the Shares by Computer Associates or Merger Subsidiary or the       
     
consummation by Computer Associates or Merger Subsidiary of the            

Merger, seeking to obtain material damages or otherwise directly or        
    
indirectly relating to the transactions contemplated by the Merger         
   
Agreement, the Offer or the Merger, (ii) seeking to restrain or            

prohibit Computer Associates' or Merger Subsidiary's ownership or          
  
operation (or that of their respective subsidiaries or affiliates)         
   
of all or any material portion of the business or assets of the            

Company and its subsidiaries, taken as a whole, or of Computer             
Associates and its subsidiaries, taken as a whole, or to compel            

Computer Associates or any of its subsidiaries or affiliates to            

dispose of or hold separate all or any material portion of the             
business or assets of the Company and its subsidiaries, taken as a         
   
whole, or of Computer Associates and its subsidiaries, taken as a          
  
whole, (iii) seeking to impose material limitations on the ability         
   
of Computer Associates or any of its subsidiaries or affiliates            

effectively to exercise full rights of ownership of the Shares,            

including, without limitation, the right to vote any Shares acquired       
     
or owned by Computer Associates or any of its subsidiaries or             
affiliates on all matters properly presented to the Company's             
stockholders, (iv) seeking to require divestiture by Computer             
Associates or any of its subsidiaries or affiliates of any Shares,         
   
or (v) that otherwise, in the judgment of Computer Associates, is          
  
likely to materially adversely affect the business, financial             
condition or results of operations of the Company and its             
subsidiaries, taken as a whole, or Computer Associates and its             
subsidiaries, taken as a whole; provided that, in the case of any          
  
instituted or pending action or proceeding described in this             
subsection (a) above by a person other than a Governmental Entity,         
   
there is a substantial probability of a determination material and         
   
adverse to Computer Associates or any of its subsidiaries or the           
 
Company or any of its subsidiaries in such action or proceeding; or        
   
            
(b)   there shall be any action taken, or any statute, rule,             
regulation, injunction, order or decree proposed, enacted, enforced,       
     
promulgated, issued or deemed applicable to the Merger Agreement,          
  
the Offer or the Merger, by any Governmental Entity or arbitrator          
  
other than the application of the waiting period provisions of the         
   
HSR Act to the Merger Agreement, the Offer or the Merger, that, in         
   
the judgment of Computer Associates, is likely, directly or             
indirectly, to result in any of the consequences referred to in            

clauses (i) through (v) of paragraph (a) above; or            
            
(c)   any change shall have occurred or been threatened (or any            

development shall have occurred or been threatened involving a             
prospective change) in the business, financial condition or results        
    
of operations of the Company or any of its subsidiaries that, in the       
     
reasonable judgment of Computer Associates, is or is likely to have        
    
a Material Adverse Effect (defined below); or            
            
(d)   there shall have occurred (i) any general suspension of             
trading in, or limitation on prices for, securities on the New York        
    
Stock Exchange, Inc. or on the AMEX, (ii) a declaration of a banking       
     
moratorium or any suspension of payments in respect of banks in the        
    
United States, (iii) any material limitation (whether or not             
mandatory) by any Governmental Entity on the extension of credit by        
    
banks or other lending institutions, (iv) a commencement of a war or       
     
armed hostilities or other national or international calamity             
directly or indirectly involving the United States which would             
          
<PAGE>  35           
          
reasonably be expected to have a Material Adverse Effect or prevent        
    
(or materially delay) the consummation of the Offer or (v) in the          
  
case of any of the foregoing existing at the time of commencement of       
     
the Offer, a material acceleration or worsening thereof; or            
            
(e)   any Consent (other than the filing of a certificate of             
merger or approval by the stockholders of the Company of the Merger        
    
(if required by Delaware Law)) required to be filed, occurred or           
 
been obtained by the Company or any of its subsidiaries or Computer        
    
Associates or any of its subsidiaries (including Merger Subsidiary)        
    
in connection with the execution and delivery of the Merger             
Agreement, the Offer and the consummation of the transactions             
contemplated by the Merger Agreement shall not have been filed,            

occurred or been obtained (other than any such Consents the failure        
    
to file, occur or obtain in the aggregate, could not reasonably be         
   
expected to (1) have a Material Adverse Effect or (2) prevent or           
 
materially delay the consummation of the Offer or the Merger); or          
 
            
(f)   the Company shall have breached or failed to perform in             
any material respect any of its covenants or agreements under the          
  
Merger Agreement, or any of the representations and warranties of          
  
the Company set forth in the Merger Agreement that is qualified as         
   
to materiality shall not be true when made or at any time prior to         
   
consummation of the Offer as if made at and as of such time, or any        
    
of the representations and warranties set forth in the Merger             
Agreement that is not so qualified shall not be true in any material       
     
respect when made or at any time prior to the consummation of the          
  
Offer as if made at and as of such time; or             
            
(g)   the Merger Agreement shall have been terminated in             
accordance with its terms; or            
            
(h)   the Board of Directors of the Company (or any special             
committee thereof) shall have withdrawn or materially modified its         
   
approval or recommendation of the Offer, the Merger or the Merger          
  
Agreement; or            
            
(i)   the Company shall have entered into, or shall have             
publicly announced its intention to enter into, an agreement or            

agreement in principle with respect to any Acquisition Proposal;           

            
which, in the sole judgment of Computer Associates in any such case, and   
         
regardless of the circumstances (including any action or omission by       
     
Computer Associates or Merger Subsidiary) giving rise to any such          
  
condition, makes it inadvisable to proceed with such acceptance for        
    
payment or payment.  The term "Material Adverse Effect" means a material   
         
adverse effect on the financial condition, business or results of          
  
operations of the Company and its subsidiaries taken as a whole, except    
        
that occurrences due solely to a disruption of the Company's or its        
    
subsidiary's businesses solely as a result of the announcement of the      
      
execution of the Merger Agreement and the transactions proposed to be      
      
consummated by the Merger Agreement shall be excluded from consideration   
         
for purposes of the effect of an action or inaction on the Company and     
      
its  subsidiaries taken as a whole.              
          
     The foregoing conditions are for the sole benefit of Computer         
   
Associates and Merger Subsidiary and may be asserted by Computer           
 
Associates in its sole discretion regardless of the circumstances          
  
          
<PAGE> 36          
          
(including any action or omission by Computer Associates or Merger         
   
Subsidiary) giving rise to any such condition or (other than the Minimum   
  
Condition) may be waived by Computer Associates and Merger Subsidiary in   
  
their sole discretion in whole at any time or in part from time to time.   
   
The failure by Computer Associates or Merger Subsidiary at any time to     

exercise its rights under any of the foregoing conditions shall not be     

deemed a waiver of any such right; the waiver of any such right with      
respect to particular facts and circumstances shall not be deemed a     
waiver  with respect to any other facts and circumstances, and each such   
 
right  shall be deemed an ongoing right which may be asserted at any      
time or from time to time.  Any determination by Computer Associates       
concerning the  events described in this Section 15 will be final and      
binding upon all parties to the Merger Agreement.       
            
16.   Certain Legal Matters; Regulatory Approvals.            
            
     General.  Except as set forth in this Section 16, based on its        
    
examination of publicly available information filed by the Company with    
        
the Commission and other publicly available information concerning the     
       
Company, Merger Subsidiary is not aware of any license or regulatory       
     
permit that appears to be material to the Company's business that might    
       
be  adversely affected by Merger Subsidiary's acquisition of Shares as     
       
contemplated herein or of any approval or other action by any government   
         
or governmental authority or agency, domestic or foreign, that would be    
        
required for the acquisition or ownership of Shares by Merger Subsidiary   
         
or Computer Associates as contemplated herein.  Should any such approval   
         
or other action be required, it is currently contemplated that, except     
      
as  described below under "State Takeover Statutes", such approval or      
    
other action will be sought.  Except as described under "Antitrust",       
   
however, there is no current intent to delay the purchase of 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 if such approvals were not obtained or such other       
   
actions were not taken adverse consequences might not result to the        
  
Company's business or certain parts of the Company's business might not    
      
have to be disposed of, any of which could cause Merger Subsidiary to      
    
elect to terminate the Offer  without the purchase of Shares thereunder.   
        
Merger Subsidiary's obligation under the Offer to accept for payment and   
       
pay for Shares is subject to certain conditions.  See Section 15.          
 
            
     State Takeover Statutes.  A number of states have adopted laws        
    
which, to varying degrees, seek to regulate attempts to acquire            

corporations that are incorporated in, or have substantial connections     
       
with, the state.  The Company, directly or through subsidiaries,           

conducts  business in a number of states throughout the United States,     
     
some of which have enacted such laws.  Based on publicly available         
 
information concerning the Company, Computer Associates does not believe   
       
that any of these laws will, by their terms, apply to the Offer or the     
     
Merger.            
            
     In addition, the constitutional validity of state statutes            

regulating acquisition attempts has been the subject of considerable       
     
litigation.  In its 1982 decision in Edgar v. MITE Corp., the Supreme      
      
Court of the United States invalidated an Illinois law that, among other   
         
things, gave Illinois officials authority to block a tender offer for      
     
any  corporation having certain defined connections with the state.  In    
      
1987, however, the Supreme Court upheld an Indiana law that prevented      
     
acquirors of a controlling stake in certain Indiana corporations from      
    
voting the acquired shares until the other shareholders had approved the   
        
acquisition.  The Court distinguished between state statutes that affect   
       
          
<PAGE>  37          
          
acquisitions of entities incorporated outside the state and those that     
     
address the  internal governance, including the scope and exercise of      
    
shareholder voting rights, of in-state corporations.  While the lower      
    
federal courts have relied on a similar distinction in subsequent cases,   
       
the precise  extent to which an individual state may regulate           
acquisitions of out-of-state corporations remains unclear.            
            
     If any government official or third party should seek to apply any    
        
state takeover law to the Offer or the Merger, Computer Associates will    
        
take such action as then appears desirable, which action may include       
     
challenging the applicability or validity of such statute in appropriate   
         
court proceedings.  In the event it is asserted that one or more state     
       
takeover statutes is applicable to the Offer or the Merger and an          
  
appropriate court does not determine that it is inapplicable or invalid    
       
as  applied to the Offer or the Merger, Computer Associates or Merger      
      
Subsidiary might be required to file certain information with, or to       
     
receive approvals from, the relevant state authorities or holders of       
     
Shares, and Merger Subsidiary might be unable to accept for payment or     
      
pay for Shares tendered pursuant to the Offer, or be delayed in           
continuing or consummating the Offer or the Merger.  In such case,         
 
Merger Subsidiary may not be obligated to accept for payment or pay for    
      
any tendered Shares.  See Section 15.            
            
     Antitrust.  Under the HSR Act and the rules that have been            

promulgated thereunder by the Federal Trade Commission (the "FTC"),        
    
certain acquisition transactions may not be consummated unless certain     
       
information has been furnished to the Antitrust Division of the            
Department  of Justice (the "Antitrust Division") and the FTC and          

certain waiting period requirements have been satisfied.  The purchase     
     
of Shares pursuant to the Offer is subject to such requirements.           

            
     Computer Associates filed a Notification and Report Form with         
   
respect to the Offer and the Merger with the Antitrust Division and the    
        
FTC on October 9, 1996, and expects the Company to have filed such form    
       
on  or about October 10, 1996.  Based upon a filing date of October 9,     
     
1996 with respect to the Notification and Report Form filed by Computer    
        
Associates, the waiting period applicable to the purchase of Shares        
    
pursuant to the Offer would be scheduled to expire at 11:59 P.M., New      
     
York City time, on Thursday, October 24, 1996.  However, prior to such     
     
time, the Antitrust Division or the FTC may extend the waiting period by   
         
requesting additional information or documentary material relevant to      
     
the Offer from Computer Associates.  If such a request is made, the        
  
waiting period will be extended until 11:59 P.M., New York City time, on   
       
the tenth day after substantial compliance by Computer Associates with     
     
such request.  Thereafter, such waiting period can be extended only by     
     
court order.            
            
     A request will be made for early termination of the waiting period    
        
applicable to the Offer.  There can be no assurance, however, that the     
      
15-day HSR waiting period will be terminated early.  Shares will not be    
        
accepted for payment or paid for pursuant to the Offer until the           
 
expiration or earlier termination of the applicable waiting period under   
         
the HSR Act.  See Section 15.  Any extension of the waiting period will    
        
not give rise to any withdrawal rights not otherwise provided for by       
     
applicable law.  See Section 4.  The Merger Agreement provides that, if    
       
by the expiration of the Offer, the applicable waiting period under the    
      
HSR  Act shall not have expired or been terminated, Merger Subsidiary      
    
shall extend the Offer from time to time until the earlier of (x) the      
    
date that is 30 days after the first scheduled Expiration Date and (y)     
     
the date that such waiting period has expired or been terminated.          
 
          
<PAGE> 38          
            
     The Merger would not require an additional filing under the HSR       
    
Act  if Computer Associates owns 50% or more of the outstanding Shares     
     
at the time of the Merger or if the Merger occurs within one year after    
      
the HSR Act waiting period applicable to the Offer expires or is           
terminated.            
            
     The Antitrust Division and the FTC frequently scrutinize the          
  
legality under the antitrust laws of transactions such as the            
acquisition of Shares by Merger Subsidiary pursuant to the Offer.  At      
    
any time before or after the consummation of any such transactions, 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 divestiture of the Shares so acquired or divestiture of         
 
substantial assets of Computer Associates or the Company.  Private         
 
parties (including individual States) may also bring legal actions under   
       
the antitrust laws.  Computer Associates does not believe that the         
 
consummation of the Offer will result in a violation of any applicable     
     
antitrust laws.  However, 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, what the result will be.  See Section 15 for certain conditions   
       
to the Offer, including conditions with respect to litigation and          

certain governmental actions.            
            
     Foreign Approvals.  According to the Company 10-K, the Company        
   
also  owns property and conducts business in a number of other foreign     
      
countries  and jurisdictions including, without limitation, Canada,        
  
Germany, France, Brazil, Japan, Singapore, and the United Kingdom.  In     
     
connection with the acquisition of the Shares pursuant to the Offer, the   
       
laws of certain of  those foreign countries and jurisdictions may          

require the filing of information with, or the obtaining of the approval   
       
of, governmental authorities in such countries and jurisdictions.  The     
     
governments in such countries and jurisdictions might also attempt to      
    
impose additional  conditions on Computer Associates' or the Company's     
     
operations conducted  in such countries and jurisdictions as a result of   
       
the acquisition of the Shares pursuant to the Offer.  There can be no      
    
assurance that any such approval can be obtained, that Computer           
Associates will be able to cause the Company or its subsidiaries to        
  
satisfy or comply with such laws or that compliance or non-compliance      
    
will not have adverse consequences for Computer Associates or the          

Company or any subsidiary of either of them. The Offer is subject to       
   
certain conditions, including conditions relating  to the legal matters    
      
referred to in this Section 16.  See Section 15.           
            
     Margin Credit Regulations.  Federal Reserve Board Regulations G,      
     
T, U and X (the "Margin Credit Regulations") restrict the extension or     
       
maintenance of credit for the purpose of buying or maintaining margin      
      
stock, if the credit is secured directly or indirectly thereby.  The       
     
borrowings under the Credit Agreements will not be directly secured by a   
         
pledge of the Shares.  In addition, Computer Associates and Merger         
   
Subsidiary believe that such borrowings will not be "indirectly secured"   
         
within the meaning of the Margin Credit Regulations, as interpreted.       
      
Accordingly, Computer Associates and Merger Subsidiary believe that the    
        
Margin Credit Regulations are not applicable to the borrowings under the   
         
Credit Facility.            
            
17.   Fees and Expenses.               
            
     Merger Subsidiary has retained D.F. King & Co., Inc. to act as the    
        
Information Agent and The Bank of New York to act as the Depositary in     
       
connection with the Offer.  The Information Agent may contact holders of   
         
          
<PAGE> 39          
          
Shares by mail, telephone, telex, telegraph and personal interviews and    
        
may request brokers, dealers and other nominee stockholders to forward     
       
materials relating to the Offer to beneficial owners.  The Information     
       
Agent and the Depositary each will receive reasonable and customary        
    
compensation for their respective services, will be reimbursed for         
  
certain reasonable out-of-pocket expenses and will be indemnified          

against certain liabilities in connection therewith, including certain     
     
liabilities under the federal securities laws.            
            
     Merger Subsidiary will not pay any fees or commissions to any         
  
broker or dealer or any other person (other than the Information Agent     
     
and the Depositary) for soliciting tenders of Shares pursuant to the       
   
Offer.  Brokers, dealers, commercial banks and trust companies will,       
   
upon request, be reimbursed by Merger Subsidiary for reasonable and        
  
necessary costs and expenses incurred by them in forwarding materials to   
       
their customers.            
            
18.   Miscellaneous.              
            
     The Offer is not being made to, nor will tenders be accepted from     
      
or  on behalf of, holders of Shares in any jurisdiction in which the       
   
making of the Offer or acceptance thereof would not be in compliance       
   
with the laws of such jurisdiction.  However, Merger Subsidiary may, in    
      
its discretion, take such action as it may deem necessary to make the      
    
Offer in any such jurisdiction and extend the Offer to holders of Shares   
       
in such jurisdiction.            
            
     No person has been authorized to give any information or make any     
       
representation on behalf of Merger Subsidiary not contained in this        
   
Offer to Purchase or in the Letter of Transmittal and, if given or made,   
       
such information or representation must not be relied upon as having       
   
been authorized.            
            
     Merger Subsidiary has filed with the Commission a Tender Offer        
    
Statement on Schedule 14D-l, together with exhibits, pursuant to Rule      
      
14d-3 of the General Rules and Regulations under the Exchange Act,         
   
furnishing certain additional information with respect to the Offer.       
       
The Schedule 14D-l and any amendments thereto, including exhibits, may     
     
be examined and copies may be obtained from the offices of the           
Commission in the manner set forth with respect to the Company in          

Section 7 of this Offer to Purchase (except that such information will     
     
not be available at the regional offices of the Commission).

                          INSTRUCTIONS            
            
     Forming Part of the Terms and Conditions of the Offer            
            
1.   Guarantee of Signatures.  Except as otherwise provided below, all     
       
signatures on this Letter of Transmittal must be guaranteed by a bank,     
       
broker, dealer, credit union, savings association or other entity that     
      
is a member of a recognized Medallion Program approved by The Securities   
         
Transfer Association, Inc. (an "Eligible Institution").  Signatures on     
      
this Letter of Transmittal need not be guaranteed (a) if this Letter of    
        
Transmittal is signed by the registered holder(s) of the Shares (which     
       
term, for purposes of this document, shall include any participant in      
     
one of the Book-Entry Transfer Facilities whose name appears on a          
 
security position listing as the owner of Shares) tendered herewith and    
       
such holder(s) have not completed the instruction entitled "Special        
   
Payment Instructions" on this Letter of Transmittal or (b) if such         
  
Shares are tendered for the account of an Eligible Institution.  In all    
       
other cases, all signatures on this Letter of Transmittal must be          
 
guaranteed by an Eligible Institution.  See Instruction 5.            
             
2.     Delivery of Letter of Transmittal and Shares.  This Letter of       
     
Transmittal is to be used either if certificates are to be forwarded       
     
herewith or, unless an Agent's Message is utilized, if delivery of         
  
Shares is to be made by book-entry transfer pursuant to the procedure      
     
set forth in Section 3 of the Offer to Purchase. Certificates for all      
     
physically delivered Shares, or a Book-Entry Confirmation of all Shares    
       
delivered electronically, as the case may be, as well as a properly        
   
completed and duly executed Letter of Transmittal (or facsimile thereof)   
        
or, in connection with a book-entry transfer, an Agent's Message, and      
     
any other documents required by this Letter of Transmittal, must be        
   
received by the Depositary at one of its addresses set forth on the        
   
front page of this Letter of Transmittal by the Expiration Date.  If a     
      
stockholder's certificate for Shares is not immediately available or       
    
time will not permit all required documents to reach the Depositary by     
      
the Expiration Date or the procedure for book-entry transfer cannot be     
      
completed on a timely basis, such stockholder's Shares may nevertheless    
       
be tendered pursuant to the guaranteed delivery procedure set forth in     
      
Section 3 of the Offer to Purchase.  Pursuant to such procedure:  (a)      
     
such tender must be made by or through an Eligible Institution, (b) a      
     
properly completed and duly executed Notice of Guaranteed Delivery         
  
substantially in the form provided by Merger Subsidiary must be received   
        
by the Depositary by the Expiration Date and (c) the certificates for      
     
all physically delivered Shares, or a Book-Entry Confirmation, as well     
      
as a properly completed and duly executed Letter of Transmittal (or        
   
facsimile thereof) (or, in the case of a book-entry delivery, an Agent's   
        
Message) and any other documents required by this Letter of Transmittal,   
        
must be received by the Depositary within three trading days on the        
   
American Stock Exchange, Inc. after the date of execution of such Notice   
        
of Guaranteed Delivery, all as provided in Section 3 of the Offer to       
    
Purchase.             
            
            The method of delivery of Shares and all other required        
   
documents, including delivery through any Book-Entry Transfer Facility,    
        
is at the option and risk of the tendering stockholder, and the delivery   
        
will be deemed made only when actually received by the Depositary.  If     
      
certificates for Shares are sent by mail, registered mail with return      
     
receipt requested, properly insured, is recommended.  In all cases,        
   
sufficient time should be allowed to ensure timely delivery.            
            
            No alternative, conditional or contingent tenders will be      
      
accepted, and no fractional Shares will be purchased.  By executing this   
         
Letter of Transmittal (or facsimile thereof), the tendering stockholder    
        
waives any right to receive any notice of the acceptance for payment of    
       
the Shares.            
            
            
            
3.    Inadequate Space.  If the space provided herein is inadequate, the   
      
          
<PAGE> 9          
             
certificate numbers and/or the number of Shares should be listed on a      
      
separate schedule attached hereto.             
             
             
            
4.     Partial Tenders (not applicable to stockholders who tender by       
     
book-entry transfer).  If fewer than all the Shares represented by any     
       
certificate delivered to the Depositary are to be tendered, fill in the    
        
number of Shares which are to be tendered in the box entitled "Number of   
         
Shares Tendered".  In such case, a new certificate for the remainder of    
       
the Shares represented by the old certificate will be sent to the          
 
person(s) signing this Letter of Transmittal, unless otherwise provided    
       
in the appropriate box on this Letter of Transmittal, as promptly as       
    
practicable following the expiration or termination of the Offer. All      
     
Shares represented by certificates delivered to the Depositary will be     
      
deemed to have been tendered unless otherwise indicated.            
             
5.     Signatures on Letter of Transmittal; Stock Powers and             
Endorsements.  If this Letter of Transmittal is signed by the registered   
         
holder(s) of the Shares tendered hereby, the signature(s) must            
correspond with the name(s) as written on the face of the certificates     
      
without alteration, enlargement or any change whatsoever.            
            
           If any of the Shares tendered hereby is held of record by       
    
two or more joint owners, all such owners must sign this Letter of         
  
Transmittal.            
            
           If any of the Shares tendered hereby are registered in          
 
different names on different certificates, it will be necessary to         
  
complete, sign and submit as many separate Letters of Transmittal as       
    
there are different registrations of certificates.            
            
           If this Letter of Transmittal is signed by the registered       
     
holder(s) of the Shares tendered hereby, no endorsements of certificates   
        
or separate stock powers are required unless payment of the purchase       
    
price is to be made, or Shares not tendered or not purchased are to be     
      
returned, in the name of any person other than the registered holder(s).   
         
Signatures on any such certificates or stock powers must be guaranteed     
      
by an Eligible Institution.            
            
           If this Letter of Transmittal is signed by a person other       
    
than the registered holder(s) of the Shares tendered hereby,            
certificates must be endorsed or accompanied by appropriate stock          
 
powers, in either case, signed exactly as the name(s) of the registered    
       
holder(s) appear(s) on the certificates for such Shares.  Signature(s)     
      
on any such certificates or stock powers must be guaranteed by an          
 
Eligible Institution.            
            
           If this Letter of Transmittal or any certificate or stock       
    
power is signed by a trustee, executor, administrator, guardian,           

attorney-in-fact, officer of a corporation or other person acting in a     
      
fiduciary or representative capacity, such person should so indicate       
    
when signing, and proper evidence satisfactory to Merger Subsidiary of     
      
the authority of such person so to act must be submitted.            
            
6.     Stock Transfer Taxes.  Except as set forth in this Instruction 6,   
         
Merger Subsidiary will pay any stock transfer taxes with respect to the    
        
sale and transfer of purchased Shares to it or its order pursuant to the   
         
Offer.  If, however, payment of the purchase price is to be made to, or    
        
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 stock      
     
transfer taxes (whether imposed on the registered holder(s), such other    
       
person or otherwise) 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 certificates listed in this   
        
Letter of Transmittal.            
          
<PAGE> 10          
            
7.    Special Payment and Delivery Instructions.  If the check for the     
       
purchase price of any Shares purchased is to be issued, or any Shares      
     
not tendered or not purchased are to be returned, in the name of a         
  
person other than the person(s) signing this Letter of Transmittal or if   
        
the check or any certificates for Shares not tendered or not purchased     
      
are to be mailed to someone other than the person(s) signing this Letter   
        
of Transmittal or to the person(s) signing this Letter of Transmittal at   
        
an address other than that shown above, the appropriate boxes on this      
     
Letter of Transmittal should be completed.  Stockholders tendering         
  
Shares by book-entry transfer may request that Shares not purchased be     
      
credited to such account at any of the Book-Entry Transfer Facilities as   
        
such Stockholder may designate under "Special Payment Instructions".  If   
        
no such instructions are given, any such Shares not purchased will be      
     
returned by crediting the account at the Book-Entry Transfer Facilities    
       
designated above.           
             
8.    Waiver of Conditions.  Subject to the terms of the Offer, Merger     
       
Subsidiary reserves the absolute right in its sole discretion to waive     
      
any of the specified conditions of the Offer (other than the Minimum       
     
Condition), in whole or in part, in the case of any Shares tendered.       
    
             
9.    31% Backup Withholding; Substitute Form W-9.  Under U.S. Federal     
       
income tax law, a stockholder whose tendered Shares are accepted for       
     
payment is required to provide the Depositary with such stockholder's      
      
correct taxpayer identification number ("TIN") on Substitute Form W-9      
      
below.  If the Depositary is not provided with the correct TIN, the        
    
Internal Revenue Service may subject the stockholder or other payee to a   
         
$50 penalty.  In addition, payments that are made to such stockholder or   
         
other payee with respect to Shares purchased pursuant to the Offer may     
      
be subject to 31% backup withholding.            
            
       Certain stockholders (including among others, all            
corporations and certain foreign individuals) are not subject to these     
      
backup withholding and reporting requirements.  In order for a foreign     
      
individual to qualify as an exempt recipient, the stockholder must         
  
submit a Form W-8, signed under penalties of perjury, attesting to that    
       
individual's exempt status. A Form W-8 can be obtained from the            
Depositary.  See the enclosed "Guidelines for Certification of Taxpayer    
       
Identification Number on Substitute Form W-9" for more instructions.       
    
            
        If backup withholding applies, the Depositary is required to       
     
withhold 31% of any such payments made to the stockholder or other         
  
payee.  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 Internal Revenue Service,         
  
provided that the required information is given to the Internal Revenue    
       
Service.            
            
        The box in Part 3 of the Substitute Form W-9 may be checked        
   
if the tendering stockholder 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 box    
       
in Part 3 is checked, the stockholder or other payee must also complete    
       
the Certificate of Awaiting Taxpayer Identification Number below in        
   
order to avoid backup withholding.  Notwithstanding that the box in Part   
        
3 is checked and the Certificate of Awaiting Taxpayer Identification       
    
Number is completed, the Depositary will withhold 31% on all payments      
     
made prior to the time a properly certified Taxpayer Identification        
   
Number is provided to the Depositary.  However, such amounts will be       
    
refunded to such Stockholder if a Taxpayer Identification Number is        
   
provided to the Depositary within 60 days.            
            
        The stockholder is required to give the Depositary the TIN         
  
(e.g., social security number or employer identification number) of the    
       
record owner of the Shares or of the last transferee appearing on the      
     
transfers attached to, or endorsed on, the Shares.  If the Shares are in   
        
more than one name or are not in the name of the actual owner, consult     
      
          
<PAGE> 11          
          
the enclosed "Guidelines for Certification of Taxpayer Identification      
     
Number on Substitute Form W-9" for additional guidance on which number     
      
to report.            
            
10.    Requests for Assistance or Additional Copies.  Requests for         
   
assistance or additional copies of the Offer to Purchase and this Letter   
        
of Transmittal may be obtained from the Information Agent at its address   
        
or telephone number set forth below.  Questions may be directed to the     
       
Information Agent.            
             
11.    Lost, Destroyed or Stolen Certificates.  If any certificate         
   
representing Shares has been lost, destroyed or stolen, the stockholder    
        
should promptly notify the Depositary.  The stockholder will then be       
     
instructed as to the steps that must be taken 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.              
            
12.    Acceptance of Tendered Shares.  Upon the terms and subject          
 
to the conditions of the Offer, Merger Subsidiary will have accepted for   
        
payment (and thereby purchased) Shares validly tendered and not            
withdrawn when, as and if Merger Subsidiary gives oral or written notice   
        
to the Depositary of its acceptance of the tenders of such Shares          
 
pursuant to the Offer.            
            
13.    Withdrawal Rights.  Tendered Shares may be withdrawn only           

pursuant to the procedure set forth in Section 4 of the Offer to           

Purchase.            
            
       Important:  This Letter of Transmittal or a facsimile copy          
 
hereof or, in the case of a book-entry delivery, an Agent's Message        
   
(together with certificates for, or a Book-Entry Confirmation with         
  
respect to, tendered Shares with any required signature guarantees and     
      
all other required documents) must be received by the Depositary, or the   
        
Notice of Guaranteed Delivery must be received by the Depositary, by the   
        
Expiration Date.

                   (1)   The number shown on this form is my correct       
     
                         Taxpayer Identification Number (or I am waiting   
         
                         for a number to be issued to me) and            
                   (2)   I am not subject to backup withholding because:   
         
                         (a) I am exempt from backup withholding, or (b)   
      
                         I have not been notified by the Internal          
  
                         Revenue Service (the "IRS") that I am subject     
       
                         to backup withholding as a result of a failure    
        
                         to report all interest or dividends, or (c) the   
         
                         IRS has notified me that I am no longer subject   
         
                         to backup withholding. Certification

                         are currently subject to backup withholding       
  
                         because of under-reporting interest             
                         or dividends on you tax return.  However, if      
      
                         after being notified by the IRS that you were     
       
                         subject to backup withholding you received        
    
                         another notification from the IRS that you are    
        
                         no longer subject to backup withholding, do not   
         
                         cross out such Item (2).

ISLANDIA, NY, October 7, 1996 - Computer Associates International, Inc.    
       
(NYSE: CA) and Cheyenne Software, Inc. (AMEX: CYE) have entered into a     
      
merger agreement for CA to acquire Cheyenne Software through a cash        
  
tender offer.  A wholly-owned subsidiary of CA will offer to purchase      
    
all outstanding shares of Cheyenne's common stock for $30.50 per share.    
      
           
The merger has been unanimously approved by the Boards of Directors of     
      
both Cheyenne and CA.  CA will fund the acquisition through cash           
balances and existing credit facilities.           
           
"We are extremely excited by the synergistic nature of this           
acquisition," said CA Chairman and CEO Charles B. Wang.  "Cheyenne is      
    
the recognized leader in storage management solutions for the Windows NT   
       
and NetWare environments.  The addition of its product suite will          

strengthen our efforts in the desktop and LAN environments.  Cheyenne's    
      
products, along with CA's Unicenter family of enterprise management        
  
products, will offer an unbeatable combination for solving the complex     
     
management problems that clients are facing today."           
           
"In addition to a strong product offering, Cheyenne's employees are an     
      
integral part of the value in this acquisition.  In recognition of their   
        
skills and talents, CA intends to retain all of Cheyenne's employees.      
     
It is expected that Cheyenne will operate as a division of CA, and that    
      
it will continue to aggressively support its current distribution          

channel strategy."           
           
           
           
"This is a tremendous opportunity for our clients, business partners,      
     
employees, and shareholders," said Cheyenne Chairman and CEO ReiJane       
   
Huai.  "CA's unparalleled development and support capabilities and         
 
financial resources will now be available to our clients, along with       
   
Cheyenne's award-winning solutions in storage management, anti-virus,      
    
and communications software.  Equally exciting is the fact that all of     
     
us at Cheyenne will have the opportunity to participate in the next        
  
chapter of Cheyenne's growth."           
          
<PAGE>          
           
In the tender offer, CA seeks to purchase at least a majority of           

Cheyenne's outstanding shares.  Consummation of the tender offer will be   
        
subject to the expiration or termination of any applicable antitrust       
    
waiting period and the receipt of all regulatory approvals.  Following     
      
completion of the tender offer, the subsidiary of CA will be merged into   
        
Cheyenne, and all of Cheyenne's shares not owned by CA will be converted   
        
into the right to receive $30.50 per share in cash.

          The Offer is conditioned upon, among other things, (1) there

majority of the total number of outstanding Shares on a fully diluted      
    
basis and (2) the expiration or termination of the applicable waiting      
    
period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

unanimously approved by the Company's Board of Directors.  The Merger      
     
Agreement provides, among other things, that, after consummation of the

such conditions to the Merger shall be fulfilled or waived, Merger         
 
Subsidiary will be merged into the Company (the "Merger"), with the        
  
Company continuing as the surviving corporation (the "Surviving           
Corporation"). Pursuant to the Merger Agreement, at the effective time     
     
of the Merger (the "Effective Time"), each outstanding Share (other than   
       
Shares owned by Computer Associates, Merger Subsidiary or any subsidiary   
       
of either of them or held by the Company as treasury stock (which shall    
      
be canceled) or by stockholders exercising appraisal rights under the      
    
Delaware General Corporation Law) will be converted into the right to      
    
receive $30.50 in cash or any higher price paid for each Share in the      
    
Offer, without interest.

stockholders of the Company, has unanimously approved the Offer and the    
      
transactions contemplated by the Merger Agreement, and unanimously         
 
recommends that the Stockholders of the Company accept the Offer and       
   
tender their Shares.           
           
          Merger Subsidiary reserves the right, at any time and from       
    
time to time, in its sole discretion, to extend the period of time         
 
during which the Offer is open if, at the scheduled expiration date of     
     
the Offer or any extension thereof, any of the conditions to the Offer     
     
shall not have been satisfied, until such time as such conditions are      
    
satisfied or waived, and for a further period of time of not more than     
     
20 business days, regardless of whether or not any of the conditions to    
      
the Offer have been satisfied, to meet the objective (which is not a       
   
condition to the Offer) that there be validly tendered and not withdrawn   
       
at least 90% of the Shares on a fully diluted basis.  Any such extension   
       
will be made by giving oral or written notice thereof to the Depositary    
      
(defined below) and will be followed as promptly as practicable by         
 
public announcement thereof.           
           
          For purposes of the Offer, Merger Subsidiary shall be deemed     
      
to have accepted for payment tendered Shares when, as and if Merger        
   
Subsidiary gives oral or written notice to The Bank of New York (the       
    
"Depositary") of its acceptance of the tenders of such Shares.  In all     
      
cases, payment for Shares accepted for payment pursuant to the Offer       
   
will be made only after timely receipt by the Depositary of (i)           
certificates for such Shares (or of a confirmation of a book-entry         
 
transfer of such Shares into the Depositary's account at one of the        
  
Book-Entry Transfer Facilities (defined in the Offer to Purchase)), (ii)   
       
a properly completed and duly executed Letter of Transmittal (or           
facsimile thereof) or an Agent's Message (defined in the Offer to          

Purchase) in connection with a book-entry transfer, and (iii) any other    
      
required documents.           
           
          Tenders of Shares made pursuant to the Offer may be           
withdrawn at any time prior to the expiration of the Offer.  Thereafter,   
       
such tenders are irrevocable, except that they may be withdrawn on or      
    
after December 9, 1996 unless theretofore accepted for payment as          

provided in the Offer to Purchase.  If Merger Subsidiary extends the       
   
period of time during which the Offer is open, is delayed in accepting     
     
for payment or paying for Shares or is unable to accept for payment or     
     
pay for Shares pursuant to the Offer for any reason, then, without         
 
prejudice to Merger Subsidiary's rights under the Offer, the Depositary    
      
may, on behalf of Merger Subsidiary, retain all Shares tendered, and       
   
such Shares may not be withdrawn except as otherwise provided in the       
   
Offer to Purchase.  For a withdrawal to be effective, a written or         
 
facsimile transmission notice of withdrawal must be timely received by     
     
the Depositary at one of its addresses set forth in the Offer to           
Purchase and must specify the name of the person who tendered the Shares   
       
to be withdrawn and the number of Shares to be withdrawn.  If the Shares   
       
to be withdrawn have been delivered to the Depositary, a signed notice     
     
of withdrawal with (except in the case of Shares tendered by an Eligible   
       
Institution (defined in the Offer to Purchase)) signatures guaranteed by   
       
an Eligible Institution must be submitted prior to the release of such     
     
Shares.  In addition, such notice must specify, in the case of Shares      
    
tendered by delivery of certificates, the name of the registered holder    
      
(if different from that of the tendering stockholder) and the serial       
   
numbers shown on the particular certificates evidencing the Shares to be   
       
withdrawn or, in the case of Shares tendered by book-entry transfer, the   
       
name and number of the account at one of the Book-Entry Transfer           
Facilities to be credited with the withdrawn Shares.             
Withdrawals may not be rescinded, and Shares withdrawn will thereafter     
     
be deemed not validly tendered for purposes of the Offer.  However,        
  
withdrawn Shares may be retendered by again following one of the           
procedures described in the Offer to Purchase at any time prior to the     
     
expiration of the Offer.             
           
          The information required to be disclosed by paragraph

             AGREEMENT AND PLAN OF MERGER dated as of October 7, 1996      
      
            among Computer Associates International, Inc., a Delaware      
      
            corporation ("Parent"), Tse-Tsehese-Staestse, Inc., a          
  
            Delaware corporation and a wholly owned subsidiary of Parent   
         
            ("Merger Subsidiary"), and Cheyenne Software, Inc., a          
  
            Delaware corporation (the "Company").               
              
              
          The parties agree as follows:              
              
              
                              ARTICLE I              
              
                              THE OFFER              
              
          SECTION 1.1.  The Offer.  (a) Provided that nothing shall    
have occurred that would result in a failure to satisfy any of the     
conditions set forth in Annex I hereto, Merger Subsidiary shall, as     
promptly as practicable after the date hereof, but in no event later     
than five business days following the public announcement of the terms     
of this Agreement, commence an offer (the "Offer") to purchase all of     
the outstanding shares of common stock, par value $.01 per share (the     
"Shares"), including the associated Rights (defined below in Section     
4.1(c)) of the Company at a price of $30.50 per Share (including such     
associated Rights), net to the seller in cash.  The Offer shall be      
subject to the condition that there shall be validly tendered in      
accordance with the terms of the Offer prior to the expiration date of     

the Offer and not withdrawn a number of Shares which, together with the    
 
Shares then owned by Parent and Merger Subsidiary, represents at least a   
 
majority of the total number of outstanding Shares, assuming the        
exercise of all outstanding options, rights and convertible securities     

(if any) and the issuance of all Shares that the Company is obligated to   
  
issue (such total number of outstanding Shares being hereinafter        
referred to as the "Fully Diluted Shares") (the "Minimum Condition") and   
 
to the other conditions set forth in Annex I hereto.  Parent and Merger    
 
Subsidiary expressly reserve the right to waive the conditions to the      
Offer and to make any change in the terms or conditions of the Offer;      
provided that, without the written consent of the Company, no change may   
  
be made which changes the form of consideration to be paid, decreases      
 
the price per Share or the number of Shares sought in the Offer, imposes   
  
conditions to the Offer in addition to those set forth in Annex I,       
changes or waives the Minimum Condition, extends the Offer (except as      
set forth in the following sentence), or makes any other change to any     

condition to the Offer set forth in Annex I which is adverse to the       
holders of Shares.  Subject to the terms of the Offer in this Agreement    
 
and the satisfaction (or waiver to the extent permitted by this       
Agreement) of the conditions to the Offer, Merger Subsidiary shall      
accept for payment all Shares validly tendered and not withdrawn       
pursuant to the Offer as soon as practicable after the applicable     
expiration date of the Offer and shall pay for all such Shares promptly    

after acceptance; provided that Merger Subsidiary may extend the Offer     

if, at the scheduled expiration date of the Offer or any extension      
thereof any of the conditions to the Offer shall not have been      
satisfied, until such time as such conditions are satisfied or waived,     
and Merger Subsidiary may extend the Offer for a further period of time    

of not more than 20 business days to meet the objective (which is not a    

condition to the Offer) that there be validly tendered, in accordance      
with the terms of the Offer, prior to the expiration date of the Offer     
(as so extended) and not withdrawn a number of Shares, which together     
with Shares then owned by Parent and Merger Subsidiary, represents at      
least 90% of the Fully Diluted Shares.  Subject to Section 9.1, if the     
condition set forth in clause (ii) of the first paragraph of Annex I is    

not satisfied as of the date the Offer would otherwise have expired,       
Merger Subsidiary shall extend the Offer until the earlier of (i) the      
date that is 30 days after the first scheduled expiration date and (ii)    

the date the condition set forth in clause (ii) of the first paragraph     

of Annex I is satisfied.              
              
          (b)  As soon as practicable on the date of commencement of       
      
the Offer, Parent and Merger Subsidiary shall (i) file with the SEC        
     
(defined below in Section 4.1(a)) a Tender Offer Statement on Schedule     
        
14D-l with respect to the Offer which will contain the offer to purchase   
          
           
<PAGE> 2           
           
and form of the related letter of transmittal (together with any     
supplements or amendments thereto, collectively the "Offer Documents")    
and (ii) cause the Offer Documents to be disseminated to holders of     
Shares.  Parent, Merger Subsidiary and the Company each agrees promptly    

to correct any information provided by it for use in the Offer Documents   
 
if and to the extent that it shall have become false or misleading in      
any material respect.  Parent and Merger Subsidiary agree to 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 federal securities laws.      
The Company and its counsel shall be given a reasonable opportunity to     
review and comment on the Schedule 14D-l prior to its being filed with     
the SEC.              
              
          SECTION 1.2.  Company Action.  (a) The Company hereby     
consents to the Offer and represents that its Board of Directors, at a     
meeting duly called and held, has (i) unanimously determined that this     

Agreement and the transactions contemplated hereby, including the Offer    

and the Merger (defined below in Section 2.1), are fair to and in the     
best interest of the Company's stockholders, (ii) unanimously approved     
this Agreement and the transactions contemplated hereby, including the     
Offer and the Merger, which approval satisfies in full the requirements    

of Section 203 of the General Corporation Law of the State of Delaware     

(the "Delaware Law"), and (iii) unanimously resolved to recommend      
acceptance of the Offer and approval and adoption of this Agreement and    

the Merger by its stockholders.  The Company further represents that     
Lazard Freres & Co. LLC has delivered to the Company's Board of         
Directors its opinion that the consideration to be paid in the Offer and   
 
the Merger is fair to the holders of Shares from a financial point of     
view.  The Company has been advised that all of its directors and       
executive officers presently intend either to tender their Shares       
pursuant to the Offer or to vote in favor of the Merger.  The Company      
will promptly furnish Parent and Merger Subsidiary with a list of its      
stockholders, mailing labels and any available listing or computer file    

containing the names and addresses of all record holders of Shares and     

lists of securities positions of Shares held in stock depositories, in     

each case as of the most recent practicable date, and will provide to      
Parent and Merger Subsidiary such additional information (including,     
without limitation, updated lists of stockholders, mailing labels and      
lists of securities positions) and such other assistance as Parent or      
Merger Subsidiary may reasonably request in connection with the Offer.     
              
          (b)  As soon as practicable on the day that the Offer is         
    
commenced the Company will file with the SEC and disseminate to holders    

of Shares a Solicitation/Recommendation Statement on Schedule 14D-9 (the   
 
"Schedule 14D-9") which shall reflect the recommendations of the           
  
Company's Board of Directors referred to above, subject to the fiduciary   
 
duties of the Board of Directors of the Company as advised in writing by   
 
Wachtell, Lipton, Rosen & Katz, counsel to the Company.  The Company,      
       
Parent and Merger Subsidiary each agrees promptly to correct any           
  
information provided by it for use in the Schedule 14D-9 if and to the     
        
extent that it shall have become false or misleading in any material       
      
respect.  The Company agrees to 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 federal securities laws.  Parent and its counsel    
         
shall be given a reasonable opportunity to review and comment on the       
      
Schedule 14D-9 prior to its being filed with the SEC.              
              
          SECTION 1.3.  Directors.  (a) Effective upon the acceptance      
       
for payment by Merger Subsidiary of a majority of the Shares pursuant to   

the Offer, Parent shall be entitled to designate the number of             

directors, rounded up to the next whole number, on the Company's Board    
of Directors that equals the product of (i) the total number of            
 
directors on the Company's Board of Directors (giving effect to the        
     
election of any additional directors pursuant to this Section) and (ii)    
the percentage that the number of Shares owned by Parent or Merger         
 
Subsidiary (including Shares accepted for payment) bears to the total     
number of Shares outstanding, and the Company shall take all action        
necessary to cause Parent's designees to be elected or appointed to the    

Company's Board of Directors, including, without limitation, increasing    
the number of directors, or seeking and accepting resignations of          
   
           
<PAGE> 3           
           
incumbent directors, or both; provided that, prior to the Effective Time   
          
(defined below in Section 2.1), the Company's Board of Directors shall     
        
always have one member who is neither a designee nor an affiliate of       
      
Parent or Merger Subsidiary nor an employee of the Company (an             

"Independent Director"). If the number of Independent Directors is         
    
reduced below one for any reason prior to the Effective Time, the          
   
departing Independent Director shall be entitled to designate a person     
        
to fill such vacancy.  No action proposed to be taken by the Company to    
         
amend or terminate this Agreement or waive any action by Parent or         
    
Merger Subsidiary shall be effective without the approval of the           
  
Independent Director.  At such times, the Company will use its best        
     
efforts to cause individuals designated by Parent to constitute the same   
          
percentage as such individuals represent on the Company's Board of         
    
Directors of (x) each committee of the Board, (y) each board of            
 
directors of each subsidiary (defined below in Section 4.1(a)) and (z)     
        
each committee of each such board.              
              
          (b)  The Company's obligations to appoint designees to the       
      
Board of Directors shall be subject to Section 14(f) of the Exchange Act   
          
(defined below in Section 4.1(d)) and Rule 14f-l promulgated thereunder.   
           
The Company shall promptly take all actions required pursuant to Section   
          
14(f) and Rule 14f-l in order to fulfill its obligations under this        
     
Section 1.3 and shall include in the Schedule 14D-9 such information       
      
with respect to the Company and its officers and directors as is           
  
required under Section 14(f) and Rule 14f-l to fulfill its obligations     
        
under this Section 1.3.  Parent will supply to the Company in writing      
       
and be solely responsible for any information with respect to itself and   
          
its nominees, officers, directors and affiliates required by Section       
      
14(f) and Rule 14f-1.              
              
                           ARTICLE II              
              
                           THE MERGER              
              
          SECTION 2.1.  The Merger.  (a) At the Effective Time, Merger    
Subsidiary shall be merged (the "Merger") with and into the Company in     
accordance with the Delaware Law, whereupon the separate existence of     
Merger Subsidiary shall cease, and the Company shall be the surviving    
corporation (the "Surviving Corporation").              
              
          (b)  The closing of the Merger (the "Closing") shall take        
     
place on the later of (x) November 30, 1996 and (y) the first business     
        
day on which all of the conditions set forth in Article VIII hereof        
shall be fulfilled or waived in accordance with this Agreement.  As soon   

as practicable following the Closing, the Company and Merger Subsidiary    

will file a certificate of merger with the Secretary of State of the       

State of Delaware and make all other filings or recordings required by    
Delaware Law in connection with the Merger.  The Merger shall become     
effective at such time as the certificate of merger is duly filed with    
the Secretary of State of the State of Delaware or, with the consent of    
the Independent Director, at such later time as is specified in the     
certificate of merger (the "Effective Time").            
              
          (c)  From and after the Effective Time, the Surviving            
 
Corporation shall possess all the rights, privileges, powers and           
  
franchises and be subject to all of the restrictions, disabilities and     
duties of the Company and Merger Subsidiary, all as provided under        
Delaware Law.                
              
          SECTION 2.2.  Conversion of Shares.  At the Effective Time:      
       
              
          (a)  each Share held by the Company as treasury stock or        
owned by Parent, Merger Subsidiary or any subsidiary of either of them     

immediately prior to the Effective Time shall be canceled, and no          
   
payment shall be made with respect thereto;              
              
          (b)  each share of common stock of Merger Subsidiary             

outstanding immediately prior to the Effective Time shall be converted     
        
           
<PAGE> 4           
           
into and become one share of common stock of the Surviving Corporation     
        
with the same rights, powers and privileges as the shares so converted     
        
and shall constitute the only outstanding shares of capital stock of the   
          
Surviving Corporation; and              
              
          (c)  each Share outstanding immediately prior to the             

Effective Time shall, except as otherwise provided in Section 2.2(a) or    
 
as provided in Section 2.4 with respect to Shares as to which appraisal    
         
rights have been exercised, be converted into the right to receive         
    
$30.50 in cash or any higher price paid for each Share in the Offer,       
      
without interest (the "Merger Consideration").              
              
          SECTION 2.3.  Surrender and Payment.  (a) Prior to the           

Effective Time, Parent shall appoint a bank or trust company (the        
"Exchange Agent") for the purpose of exchanging certificates          
representing Shares for the Merger Consideration.  Parent will make        
     
available to the Exchange Agent, as needed, the Merger Consideration to    
   
be paid in respect of the Shares (the "Exchange Fund").  For purposes of   
 
determining the Merger Consideration to be made available, Parent shall    
assume that no holder of Shares will perfect his right to appraisal of    
his Shares.  Promptly after the Effective Time, Parent will send, or      
will cause the Exchange Agent to send, to each holder of Shares at the    
Effective Time a letter of transmittal for use in such exchange (which    
shall specify that the delivery shall be effected, and risk of loss and    
title shall pass, only upon proper delivery of the certificates            
 
representing Shares to the Exchange Agent).  The Exchange Agent shall,    
pursuant to irrevocable instructions, make the payments provided in this   
          
Section 2.3.  The Exchange Fund shall not be used for any other purpose,   

except as provided in this Agreement.              
              
          (b)  Each holder of Shares that have been converted into a       
      
right to receive the Merger Consideration, upon surrender to the           
  
Exchange Agent of a certificate or certificates representing such          
   
Shares, together with a properly completed letter of transmittal           
  
covering such Shares and such other documents as may be reasonably         
    
requested, will be entitled to receive the Merger Consideration payable    
         
in respect of such Shares.  Until so surrendered, each such certificate    
         
shall, after the Effective Time, represent for all purposes, only the      
       
right to receive such Merger Consideration.              
              
          (c)  If any portion of the Merger Consideration is to be         
    
paid to a person other than the registered holder of the Shares            
 
represented by the certificate or certificates surrendered in exchange     
        
therefor, it shall be a condition to such payment that the certificate     
        
or certificates so surrendered shall be properly endorsed or otherwise     
        
be in proper form for transfer and that the person requesting such         
    
payment shall pay to the Exchange Agent any transfer or other taxes        
     
required as a result of such payment to a person other than the            
 
registered holder of such Shares or establish to the satisfaction of the   
          
Exchange Agent that such tax has been paid or is not payable.  For         
    
purposes of this Agreement, "person" means an individual, a corporation,   
          
a partnership, an association, a trust or any other entity or              
organization, including a government or political subdivision or any       
      
agency or instrumentality thereof.              
              
          (d)  After the Effective Time, there shall be no further         
    
registration of transfers of Shares.  If, after the Effective Time,        
     
certificates representing Shares are presented to the Surviving            
 
Corporation, they shall be canceled and exchanged for the consideration    
         
provided for, and in accordance with the procedures set forth, in this     
        
Article II.              
              
          (e)  Any portion of the Exchange Fund made available to the    
Exchange Agent pursuant to Section 2.3(a) that remains unclaimed by the    
holders of Shares six months after the Effective Time shall be returned    
         
to Parent, upon demand, and any such holder who has not exchanged his    
Shares for the Merger Consideration in accordance with this Section 2.3    
prior to that time shall thereafter look only to Parent for payment of     
the Merger Consideration in respect of his Shares.  Notwithstanding the    

foregoing, Parent shall not be liable to any holder of Shares for any      

amount paid to a public official pursuant to applicable abandoned          
   
property laws.  Any amounts remaining unclaimed by holders of Shares       
      
           
<PAGE> 5           
           
immediately prior to such time as such amounts would otherwise escheat     
        
to or become property of any governmental entity shall, to the extent      
       
permitted by applicable law, become the property of Parent free and        
     
clear of any claims or interest of any person previously entitled          
   
hereto.              
              
          (f)  Any portion of the Merger Consideration made available      
       
to the Exchange Agent pursuant to Section 2.3(a) to pay for Shares for     
        
which appraisal rights have been perfected shall be returned to Parent,    
         
upon demand.              
              
          SECTION 2.4.  Dissenting Shares.  Notwithstanding Section        
     
2.2, Shares outstanding immediately prior to the Effective Time and held   
          
by a holder who has not voted in favor of the Merger or consented          
   
thereto in writing and who has demanded appraisal for such Shares in       
      
accordance with Delaware Law shall not be converted into a right to        
     
receive the Merger Consideration, unless such holder fails to perfect or   
          
withdraws or otherwise loses his right to appraisal.  If after the         
    
Effective Time such holder fails to perfect or withdraws or loses his      
       
right to appraisal, such Shares shall be treated as if they had been       
      
converted as of the Effective Time into a right to receive the Merger      
       
Consideration.  The Company shall give Parent prompt notice of any         
    
demands received by the Company for appraisal of Shares, and Parent        
     
shall have the right to participate in all negotiations and proceedings    
         
with respect to such demands.  The Company shall not, except with the      
       
prior written consent of Parent, make any payment with respect to, or      
       
settle or offer to settle, any such demands.              
              
          SECTION 2.5.  Stock Options.  (a) At the Effective Time,         
    
each of the then outstanding Company Options (defined below) shall by      
       
virtue of the Merger, and without any further action on the part of any    
         
holder thereof, become fully exercisable and vested and be assumed by      
       
Parent and converted into an option to purchase that number of shares of   
          
common stock, par value $.10 per share ("Parent Common Stock"), of         
    
Parent determined by multiplying the number of Shares subject to such      
       
Company Option at the Effective Time by the quotient obtained by           
  
dividing (x) $30.50 by (y) the average closing price of Parent Common      
       
Stock on the New York Stock Exchange Composite Tape for the 20             

consecutive trading days immediately prior to the Effective Time (such     
        
quotient, the "Conversion Number"), at an exercise price per share of      
       
Parent Common Stock equal to the quotient obtained by dividing (x) the     
        
exercise price per Share of such Company Option immediately prior to the   
          
Effective Time by (y) the Conversion Number.  If the foregoing             

calculation results in an assumed Company Option being exercisable for a   
          
fraction of a share of Parent Common Stock, then the number of shares of   
          
Parent Common Stock subject to such option shall be rounded down to the    
         
nearest whole number of shares.  Except as otherwise set forth in this     
        
Section 2.5, the term, status as an "incentive stock option" under         
    
Section 422 of the Internal Revenue Code of 1986, as amended, and the      
       
rules and regulations thereunder (the "Code"), if applicable, and all      
       
other terms and conditions of Company Options will, to the extent          
   
permitted by law and otherwise reasonably practicable, be unchanged.       
       
The Company shall take, or cause to be taken, all actions which are        
     
necessary, proper or advisable under the Stock Plans to make effective     
        
the transactions contemplated by this Section 2.5.  "Company Options"      
       
means any option granted, and not exercised or expired, to a current or    
         
former employee, director or independent contractor of the Company or      
       
any of its subsidiaries or any predecessor thereof to purchase Shares      
       
pursuant to any stock option, stock bonus, stock award, or stock           
  
purchase plan, program, or arrangement of the Company or any of its        
     
subsidiaries or any predecessor thereof (collectively, the "Stock          
   
Plans") or any other contract or agreement entered into by the Company     
        
or any of its subsidiaries.              
              
          (b)  Parent shall take all corporate action necessary to         
    
reserve for issuance a sufficient number of shares of Parent Common        
     
Stock for delivery pursuant to the terms set forth in this Section 2.5.    
          
Parent shall cause the shares of Parent Common Stock issuable upon         
    
exercise of the assumed Company Options to be registered, or to be         
    
issued pursuant to a then effective registration statement, no later       
      
than 90 days after the Effective Time on Form S-8 promulgated by the SEC   
          
and shall use its best efforts to maintain the effectiveness of such       
       
registration statement or registration statements for so long as such      
       
           
<PAGE> 6           
            
assumed Company Options remain outstanding.  With respect to those         
    
individuals who subsequent to the Merger will be subject to the            
 
reporting requirements under Section 16(a) of the Exchange Act, Parent     
        
shall administer the Company Options assumed pursuant to this Section      
       
2.5 in a manner that complies with Rule 16b-3 promulgated by the SEC       
      
under the Exchange Act, but shall have no responsibility for such          
   
compliance by the Company or its predecessors.

          SECTION 3.1.  Certificate of Incorporation.  The certificate     
        
of incorporation of Merger Subsidiary in effect at the Effective Time      
       
shall be the certificate of incorporation of the Surviving Corporation     
        
until amended in accordance with applicable law, except that the name of   
          
the Surviving Corporation shall be changed to the name of the Company.     
        
              
          SECTION 3.2.  Bylaws.  The bylaws of Merger Subsidiary in        
     
effect at the Effective Time shall be the bylaws of the Surviving          
   
Corporation until amended in accordance with applicable law.              
              
          SECTION 3.3.  Directors and Officers.  From and after the        
     
Effective Time, until successors are duly elected or appointed and         
    
qualified in accordance with applicable law, (i) the directors of Merger   
          
Subsidiary at the Effective Time shall be the directors of the Surviving   
          
Corporation, and (ii) the officers of the Merger Subsidiary at the         
    
Effective Time shall be the officers of the Surviving Corporation.

          SECTION 4.1.  Representations and Warranties of the Company.     
         
The Company represents and warrants to Parent and Merger Subsidiary as     
        
follows:              
              
          (a)  Organization, Standing and Corporate Power.  Each of        
     
the Company and each of its Significant Subsidiaries is a corporation      
       
duly organized, validly existing and in good standing under the laws of    
         
the jurisdiction in which it is incorporated and has the requisite         
    
corporate power and authority to carry on its business as now being        
     
conducted.  Each of the Company and each of its Significant Subsidiaries   
          
is duly qualified or licensed to do business and is in good standing in    
         
each jurisdiction in which the nature of its business or the ownership     
        
or leasing of its properties makes such qualification or licensing         
    
necessary, other than in such jurisdictions where the failure to be so     
        
qualified or licensed (individually or in the aggregate) could not         
    
reasonably be expected to have a material adverse effect on the            
 
financial condition, business or results of operations of the Company      
       
and its subsidiaries taken as a whole except that occurrences due solely   
          
to a disruption of the Company's or its subsidiary's businesses solely     
        
as a result of the announcement of the execution of this Agreement and

withheld or delayed) in no event representing commitments on behalf of     
        
the Company or any of its subsidiaries of more than $500,000 for any       
      
transaction or $1,000,000 for any series of transactions, (xii) any        
     
material labor dispute, other than routine individual grievances, or any   
          
activity or proceeding by a labor union or representative thereof to       
      
organize any employees of the Company or any of its subsidiaries, which    
         
employees were not subject to a collective bargaining agreement at June    
         
30, 1996, or any material lockouts, strikes, slowdowns, work stoppages     
        
or threats thereof by or with respect to such employees or (xiii) any      
       
agreement, commitment, arrangement or undertaking by the Company or any    
         
of its subsidiaries to perform any action described in clauses (i)         
    
through (xii).              
              
          (h)  Litigation.  Except as disclosed in the Company Filed       
      
SEC Documents or in Section 4.1(h) of the Disclosure Schedule, there is    
         
no suit, action or proceeding pending or, to the knowledge of the          
   
Company, threatened against or affecting the Company or any of its         
    
subsidiaries that, individually or in the aggregate, could reasonably be   
          
expected to (i) have a Material Adverse Effect, (ii) impair the ability    
         
of the Company to perform its obligations under this Agreement or (iii)    
         
prevent or materially delay the consummation of the Offer, the Merger or   
          
any of the other transactions contemplated by this Agreement, nor is       
      
there any judgment, decree, injunction, rule or order of any              
Governmental Entity or arbitrator outstanding against the Company or any   
          
of its subsidiaries having, or which, insofar as reasonably can be         
    
foreseen, in the future would have, any such effect.  Section 4.1(h) of    
         
the Disclosure Schedule sets forth as of the date hereof, with respect     
        
to any pending suit, action or proceeding to which the Company or any      
       
its subsidiaries is a party and which involves claims which if adversely   
          
determined would exceed $500,000, the forum, the parties thereto, the      
       
subject matter thereof and the amount of damages claimed.

          (i)  Absence of Changes in Stock and Benefit Plans.  Except      
       
as disclosed in the Company Filed SEC Documents or Section 4.1(i) of the   
          
Disclosure Schedule, since June 30, 1996, there has not been (i) any       
      
adoption or amendment by the Company or any of its subsidiaries of any     
        
Stock Plan or any acceleration, amendment or change of the period of       
      
exercisability or vesting of any Company Options or restricted stock,      
       
stock bonus or other awards under the Stock Plans (including any           
  
discretionary acceleration of the exercise periods or vesting by the       
      
Company's Board of Directors or any committee thereof or any other         
    
persons administering a Stock Plan) or authorization of cash payments in   
          
exchange for any Company Options, restricted stock, stock bonus or other   
          
awards granted under any of such Stock Plans; or (ii) any adoption or

current or former employee, officer or director of the Company or any of   
          
its subsidiaries or any beneficiary thereof entered into, maintained or    
         
contributed to, as the case may be, by the Company or any of its           
  
subsidiaries (collectively, "Benefit Plans") where the expense of such     
        
Benefit Plan, or amendment thereto, as the case may be, is material,       
      
other than those Benefit Plans maintained outside of the United States     
        
primarily for the benefit of persons substantially all of whom are non-    
        
resident aliens with respect to the United States ("Foreign Benefit        
     
Plans").              
              
          (j)  Participation and Coverage in Benefit Plan.  Except for     
        
amendments and other actions described in Section 4.1(i) of the            
 
Disclosure Schedule, except with respect to changes required by            
 
applicable law, and except as disclosed in the Company Filed SEC           
  
Documents or Section 4.1(j) of the Disclosure Schedule, there has been     
        
no written interpretation or announcement (whether or not written) by      
       
the Company or any of its subsidiaries relating to, or change in           
  
employee participation or coverage under, any Benefit Plan, other than a   
          
Foreign Benefit Plan, which would increase materially the expense of       
      
maintaining such Benefit Plan above the level of the expense incurred in   
          
respect thereof for the fiscal year ended on June 30, 1996.              
              
          (k)  ERISA Compliance.  (i)  Section 4.1(k) of the              
Disclosure Schedule contains a list of (A) all "employee pension benefit   
          
plans" (defined in Section 3(2) of the Employee Retirement Income          
   
Security Act of 1974, as amended ("ERISA")), "employee welfare benefit     
        
plans" (defined in Section 3(l) of ERISA) and all other Benefit Plans      
       
maintained, or contributed to, by the Company or any of its subsidiaries   
          
or ERISA affiliates (defined below) for the benefit of any current or      
       
former employees, officers or directors of the Company or any of its       
      
subsidiaries or ERISA affiliates or under which the Company or any of      
       
its subsidiaries or ERISA affiliates has any liability other than          
   
Foreign Benefit Plans ("U.S. Benefit Plans") and (B) all Stock Plans.      
        
For purposes of this Agreement, "ERISA affiliate" of the Company means     
        
any person which, together with the Company or any of its subsidiaries,    
         
would be treated as a single employer under Section 414 of the Code.       
       
The only Benefit Plans described in clause (A) of the preceding sentence   
          
which constitute an "employee pension benefit plan" defined in Section     
        
3(2) of ERISA (the "Pension Plans") are identified as such in Section      
       
4.1(k) of the Disclosure Schedule.              
              
          (ii)  Each material U.S. Benefit Plan has been maintained        
     
and administered in compliance in all material respects with its terms     
        
and with the requirements prescribed by any and all applicable statutes,   
          
orders, rules and regulations, and is, to the extent required by           
  
applicable law or contract, fully funded without having any material       
      
deficit or material unfunded actuarial liability.  Any Benefit Plan        
     
intended to be qualified under Section 401(a) of the Code has been         
    
determined by the Internal Revenue Service to be so qualified and,         
    
except as set forth in Section 4.1(k) of the Disclosure Schedule,          
   
nothing has occurred to cause the loss of such qualified status except     
        
where such occurrence could reasonably be expected to be cured without     
        
the incurrence by the Company of any liability or expense that would be    
         
material to the Company and its subsidiaries.              
           
<PAGE> 12           
              
          (iii)  No Benefit Plan is covered by Title IV of ERISA or        
     
Section 412 of the Code.  Neither the Company nor any of its              
subsidiaries has incurred or expects to incur any liability under Title    
         
IV of ERISA that has not already been satisfied or any liability or        
     
penalty under Section 4975 or 4980B of the Code or Section 502(i) of       
      
ERISA that has not already been satisfied.              
              
          (iv)  Except as disclosed in Section 4.1(k)(iv) of the           
  
Disclosure Schedule, there are no pending or anticipated claims against    
         
or otherwise involving any of the Benefit Plans and no suit, action or     
        
other litigation has been brought against or with respect to any Benefit   
          
Plan (excluding, in each case, claims for benefits incurred in the         
    
ordinary course of Benefit Plan activities) which would be material to     
        
the Company and its Subsidiaries.              
              
          (v)  All material contributions, reserves or premium             

payments required to be made as of the date hereof to or with respect to   
          
the Benefit Plans have been made or provided for except to the extent      
       
failure to do so would not impair the continued operation of the           
  
relevant Benefit Plan.              
              
          (vi)  Except as required by law or as disclosed in Section       
      
4.1(k)(vi) of the Disclosure Schedule, neither the Company nor any of      
       
its subsidiaries has any material obligations for post-retirement or       
      
post-termination health and life benefits under any U.S. Benefit Plan.     
        
              
          (l)  Taxes.  As used in this Agreement, "tax" or "taxes"         
    
shall include all Federal, state, local and foreign income, property,      
       
sales, excise and other taxes, tariffs or governmental charges or          
   
assessments of any nature whatsoever as well as any interest, penalties    
         
and additions thereto.  Except as disclosed in Schedule 4.1(l) of the      
       
Disclosure Schedule:              
              
          (i)  The Company and each of its subsidiaries have timely        
     
filed all tax returns, statements, reports and forms required to be        
     
filed with any tax authority and in accordance with all applicable laws.   
           
All such tax returns are correct and complete in all material respects.    
          
All taxes owed by the Company and any of its subsidiaries (whether or      
       
not shown on any tax return) have been paid other than where failure to    
         
do so could reasonably be expected to be cured without the incurrence by   
          
the Company of any material liability.  There are no material Liens on     
        
any of the assets of the Company or any of its subsidiaries that arose     
        
in connection with any failure (or alleged failure) to pay any tax.        
     
              
          (ii)  The Company and each of its subsidiaries has withheld      
       
and timely paid all taxes required to have been withheld and paid in       
      
connection with amounts paid or owing to any employee, independent         
    
contractor, creditor, stockholder, or other third party other than where   
          
failure to do so could reasonably be expected to be cured without the      
       
incurrence by the Company of any material liability.              
              
          (iii)  Neither the Company nor any of its subsidiaries           
  
expects any authority to assess any additional taxes against the Company   
          
or any of its subsidiaries for any period for which tax returns have       
      
been filed.  No dispute or claim concerning any tax liability of the       
      
Company or any of its subsidiaries has been proposed or claimed in         
    
writing by any authority.              
              
          (iv)  Neither the Company nor any of its subsidiaries has        
     
waived any statute of limitations in respect of taxes or agreed to any     
        
extension of time with respect to a tax assessment or deficiency.          
   
              
          (v)  Neither the Company nor any of its subsidiaries has         
    
filed a consent pursuant to Section 341(f) of the Code concerning          
   
collapsible corporations.  Neither the Company nor any of its              
subsidiaries is a party to any tax allocation or sharing agreement.        
      
Neither the Company nor any of its subsidiaries has any material           
  
liability for the taxes of any person (other than the Company and any of   
          
           
<PAGE> 13           
           
its subsidiaries that is currently a member of the Company's affiliated    
         
group filing a consolidated federal income tax return) under Treas. Reg.   
          
1.1502-6 (or any similar provision of state, local, or foreign law), as    
         
a transferee or successor, by contract, or otherwise.              
              
          (vi)  As of the date of the most recent financial statements     
        
included in the Company Filed SEC Documents, the unpaid taxes of the       
      
Company and its subsidiaries did not exceed the liability for taxes        
     
(rather than any reserve for deferred taxes established to reflect         
    
timing differences between book and tax income) set forth on the face of   
          
such financial statements.                
              
          (vii)  Neither the Company nor any of its subsidiaries is        
     
required to include in income any adjustment pursuant to Section 481(a)    
         
of the Code (or similar provisions of other law or regulations) in its     
        
current or in any future taxable period by reason of a change in           
  
accounting method; nor does the Company or any of its subsidiaries have    
         
any knowledge that the Internal Revenue Service (or other taxing           
  
authority) has proposed or is considering proposing, any such change in    
         
accounting method.  Neither the Company nor any of its subsidiaries is a   
          
party to any agreement, contract, or arrangement that, individually or     
        
collectively, could give rise to the payment of any material amount        
     
(whether in cash or property, including Shares) that would not be          
   
deductible pursuant to the terms of Sections 162(a)(1), other than         
    
amounts which may be required to be capitalized pursuant to Section 263    
         
or other applicable sections of the Code, 162(m), 162(n) or 280G of the    
         
Code.              
              
          (m)  State Takeover Statutes; Rights Agreement.  (i) The         
    
Board of Directors of the Company has approved the Offer, the Merger and   
          
this Agreement, and such approval is sufficient to render inapplicable     
        
to the Offer, the Merger, this Agreement and the other transactions        
     
contemplated hereby, the provisions of Section 203 of Delaware Law.  To    
         
the best of the Company's knowledge, no other "fair price",              
"moratorium", "control share acquisition", or other anti-takeover          
   
statute or similar statute or regulation, applies or purports to apply     
        
to the Offer, the Merger, this Agreement or any of the other              
transactions contemplated hereby.              
              
          (ii)  The Company has delivered to Parent a complete and         
    
correct copy of the Rights Agreement, including all amendments and         
    
exhibits thereto.  The Company has taken, and as soon as possible after    
         
the date hereof (but in no event later than two business days after the    
         
date hereof), the Rights Agent will take, all actions necessary or         
    
appropriate to amend the Rights Agreement to ensure that the execution     
        
of this Agreement, the announcement or making of the Offer, the            
 
acquisition of Shares pursuant to the Offer and the Merger and the other   
          
transactions contemplated in this Agreement will not cause Parent or any   
          
of its affiliates to be considered an Acquiring Person (defined in the     
        
Rights Agreement), the occurrence of a Distribution Date or Shares         
    
Acquisition Date (each defined in the Rights Agreement) or the             

separation of the Rights from the underlying Shares, and will not give     
        
the holders thereof the right to acquire securities of any party hereto.   
          
              
          (n)  Brokers; Schedule of Fees and Expenses.  No broker,         
    
investment banker, financial advisor or other person, other than Lazard    
         
Freres & Co. LLC and Broadview Associates LLC, the fees and expenses of    
         
which will be paid by the Company (and a copy of whose engagement          
   
letters and a calculation of the fees that would be due thereunder has     
        
been provided to Parent), is entitled to any broker's, finder's,           
  
financial advisor's or other similar fee or commission in connection       
      
with the transactions contemplated by this Agreement based upon            
 
arrangements made by or on behalf of the Company or any of its             

subsidiaries.  Assuming consummation of the Offer and the Merger, no       
      
such engagement letter obligates the Company to continue to use their      
       
services or pay fees or expenses in connection with any future             

transaction.              
              
          (o)  Permits; Compliance with Laws.  Each of the Company and     
        
its subsidiaries has in effect all federal, state, local and foreign

on its business as now conducted, and there has occurred no default        
     
under any such Permit, except for the absence of Permits and for           
  
defaults under Permits which absence or defaults, individually or in the   
          
aggregate, could not reasonably be expected to have a Material Adverse     
        
Effect.  The Company and its subsidiaries have been, and are, in           
  
compliance in all material respects with all applicable statutes, laws     
        
or material ordinances, regulations, rules, judgments, decrees or orders   
          
of any Governmental Entity, and neither the Company nor any of its         
    
subsidiaries has received any notice from any Governmental Entity or any   
          
other person that either the Company or any of its subsidiaries is in      
       
violation of, or has violated, in any material respect any applicable      
       
statutes, laws or material ordinances, regulations, rules, judgments,      
       
decrees or orders.              
              
          (p)  Contracts; Debt Instruments.  (i)  Except as otherwise

to:

advisors to cooperate with Parent in its investigation of the business

that such person may be considering making, or that has made, an

Company's Board of Directors from taking and disclosing to the Company's   
          
stockholders a position with respect to a tender offer pursuant to Rules

considering making, or that has made, an Acquisition Proposal and will

assets of, the Company or any of its subsidiaries, other than the

other anti-takeover statute, or similar statute or regulation shall

<PAGE> 21

Merger and the other transactions contemplated hereby, may be              
consummated as promptly as practicable on the terms contemplated hereby    
         
and otherwise to minimize the effect of such statute or regulation on      
       
the Offer, the Merger and the other transactions contemplated hereby.      
       
              
          (b)  Except as otherwise provided in Section 4.1(m)(ii), the     
        
Company shall not redeem the Rights or amend (other than to delay the      
       
Distribution Date or to render the Rights inapplicable to the Offer and    
         
the Merger) or terminate the Rights Agreement prior to the Effective       
      
Time unless required to do so by a court of competent jurisdiction.

take all action necessary to cause Merger Subsidiary to perform its        
     
obligations under this Agreement and to consummate the Offer and the       
      
Merger on the terms and conditions set forth in this Agreement.            
 
              
          SECTION 6.2.  Voting of Shares.  Parent agrees to make a         
    
quorum and vote all Shares acquired in the Offer or otherwise              
beneficially owned by it in favor of adoption of this Agreement at the     
        
Company Stockholder Meeting.              
              
          SECTION 6.3.  Indemnification. For six years after the           
  
Effective Time, Parent will indemnify and hold harmless the present and    
         
former officers, directors, employees and agents of the Company (the       
      
"Indemnified Parties") in respect of acts or omissions occurring on or     
        
prior to the Effective Time to the extent provided under the Company's     
        
certificate of incorporation and bylaws in effect on the date hereof;      
       
provided that such indemnification shall be subject to any limitation      
       
imposed from time to time under applicable law.  For four years after      
       
the Effective Time, Parent will cause the Surviving Corporation to         
    
provide officers' and directors' liability insurance in respect of acts    
         
or omissions occurring on or prior to the Effective Time covering each     
        
such person currently covered by the Company's officers' and directors'    
         
liability insurance policy on terms substantially similar to those of      
       
such policy in effect on the date hereof, provided that in satisfying      
       
its obligation under this Section, Parent shall not be obligated to        
     
cause the Surviving Corporation to pay premiums in excess of 105% of the   
          
amount per annum the Company paid in its last full fiscal year, which      
       
amount has been disclosed to Parent and if the Surviving Corporation is    
         
unable to obtain the insurance required by this Section 6.3, it shall      
       
obtain as much comparable insurance as possible for an annual premium      
       
equal to such maximum amount.  Without limitation of the foregoing, in     
        
the event any such Indemnified Party is or becomes involved in any         
    
capacity in any action, proceeding or investigation in connection with     
        
any matter relating to the Merger, the Offer or this Agreement occurring   
          
on or prior to the Effective Time, Parent shall pay as incurred such       
      
Indemnified Party's reasonable legal and other expenses (including the     
        
cost of any investigation and preparation) incurred in connection          
   
therewith.              
              
          SECTION 6.4.  Employees.  (a) Parent agrees to honor in          
   
accordance with their terms all Benefit Plans (including employment        
     
agreements) previously delivered to Parent and all accrued benefits        
     
vested thereunder; it being understood and agreed that nothing in this     
        
Section 6.4(a) shall prevent Parent from terminating any such Benefit      
       
Plan in accordance with its terms.  For purposes of this Section 6.4(a),   
          
any Benefit Plan that is a Company Filed SEC Document shall be deemed to   
          
have been delivered to Parent.              
              
          (b)  Parent agrees to provide employees of the Company and       
      
its subsidiaries retained by Parent with employee benefits in the          
   
aggregate no less favorable than those benefits provided to Parent's       
      
similarly situated employees; provided that Parent shall be under no       
      
obligation to retain any employee or group of employees of the Company     
        
or its subsidiaries.

Entity under any Antitrust Laws (defined below) with respect to any such

other party of any communication with, and any proposed understanding,     
        
undertaking, or agreement with, any Governmental Entity regarding any

Entity, the opportunity to attend and participate.              
              
          (b)  Each of Parent and the Company shall use all reasonable     
        
efforts to resolve such objections, if any, as may be asserted by any

waiver with respect to any other facts and circumstances, and each such    
         
right shall be deemed an ongoing right which may be asserted at any time   
          
or from time to time.  Any determination by Parent concerning the events   
          
described in this Section will be final and binding upon all parties.

Evaluation Material.

<PAGE> 3           
           
party, the party so deciding will promptly inform the other party of       
    
that decision.  In that case, or at any time upon the request of either    
        
disclosing party for any reason, each receiving party will promptly        
    
deliver to the disclosing party or, at the option of the receiving         
  
party, destroy all written (and electronic) Evaluation Material (and all   
        
copies thereof and extracts therefrom) furnished to the receiving party    
       
or its Representatives by or on behalf of the disclosing party pursuant    
       
hereto. In the event of such a decision or request, all other Evaluation   
        
Material prepared by the requesting party shall be destroyed and no copy   
        
thereof shall be retained, and in no event shall either party be           

obligated to disclose or provide the Evaluation Material prepared by it    
       
or its Representatives to the other party.  Notwithstanding the return     
      
or destruction of the Evaluation Material, each party and its            
Representatives will continue to be bound by their obligations of          
 
confidentiality and other obligations hereunder.            
            
     (6)  No Representation of Accuracy.  Each party understands and       
     
acknowledges that neither party nor any of its Representatives makes any   
         
representation or warranty, express or implied, as to the accuracy or      
      
completeness of the Evaluation Material made available by it or to it.     
        
Each party agrees that neither party nor any of its Representatives        
   
shall have any liability to the other party or to any of its            
Representatives relating to or resulting from the use of or reliance       
    
upon such other party s Evaluation Material or any errors therein or       
    
omissions therefrom. Only those representations or warranties which are    
       
made in a final definitive agreement regarding the Transaction, when, as   
        
and if executed, and subject to such limitations and restrictions as may   
        
be specified therein, will have any legal effect.            
            
     (7)  Definitive Agreements.  Each party understands and agrees        
   
that no contract or agreement providing for any Transaction involving      
     
the parties shall be deemed to exist between the parties unless and        
   
until a final definitive agreement has been executed and delivered.        
    
Each party also agrees that unless and until a final definitive            
agreement regarding a Transaction between the parties has been executed    
       
and delivered, neither party will be under any legal obligation of any     
      
kind whatsoever with respect to such a Transaction by virtue of this       
    
Agreement except for the matters specifically agreed to herein.  For       
    
purposes of this paragraph, the term definitive agreement does not         
  
include an executed letter of intent or any other preliminary written      
     
agreement.  Both parties further acknowledge and agree that each party     
      
reserves the right, in its sole discretion, to provide or not provide      
     
Evaluation Material to the receiving party under this Agreement, to        
   
reject any and all proposals made by the other party or any of its         
  
Representatives with regard to a Transaction between the parties, and to   
        
terminate discussions and negotiations at any time.            
            
     (8)  Injunctive Relief.  It is further understood and agreed that     
       
money damages would not be a sufficient remedy for any breach of this      
      
Agreement by either party or any of its Representatives and that the       
    
non-breaching party shall be entitled to equitable relief, including       
     
injunction and specific performance, as a remedy for any such breach.      
       
Such remedies shall not be deemed to be the exclusive remedies for a       
     
breach of this Agreement but shall be in addition to all other remedies    
        
available at law or equity.            
            
     (9)  Waiver; Invalidity.  It is understood and agreed that no         
   
failure or delay by either party in exercising any right, power or         
   
privilege hereunder shall operate as a waiver thereof, nor shall any       
     
single or partial exercise thereof preclude any other or future exercise   
         
thereof or the exercise of any other right, power or privilege            
hereunder.  In case any provision of this Agreement shall be invalid,      
     
illegal or unenforceable, the validity, legality and enforceability of     
      
the remaining provisions of this Agreement shall not in any way be         
  
affected or impaired thereby.
