ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

     On January 16, 1997, Minimum Acquisition Sub, Inc., a Delaware 
corporation ("Merger Sub"), was merged with and into MAXM, pursuant to an 
Agreement and Plan of Merger and Reorganization dated as of December 10, 1996 
(the "Agreement"), among the Registrant, Merger Sub and MAXM. See Exhibit 2.1 
attached hereto.  The terms of the Agreement were determined through arms' 
length negotiations between the Registrant and MAXM. There was no material 
relationship between MAXM and the Registrant or any of Registrant's 
affiliates, any director or officer of the Registrant, or any associate of 
any such director or officer.

     The merger of Merger Sub with and into MAXM (the "Merger") became 
effective at the time of the filing of a Certificate of Merger with the 
Delaware Secretary of State on January 16, 1997 (the "Effective Time").  At 
the Effective Time: (a) Merger Sub ceased to exist; (b) MAXM, as the 
surviving corporation in the Merger, became a wholly owned subsidiary of the 
Registrant; and (c) by virtue of the Merger and without any further action on 
the part of the Registrant, Merger Sub, or MAXM, each outstanding share of 
voting capital stock of MAXM (the "MAXM Shares") was converted into the right 
to receive the voting common stock of the Registrant (the "Boole Common 
Stock") as follows:

               (i)  Each share of MAXM's Class A preferred stock, par value 
$.01 per share, issued and outstanding immediately prior to the Effective 
Time was converted into the right to receive a fraction of a share of Boole 
Common Stock determined by dividing $3.305 plus dividends accrued from 
December 31, 1996 to the Effective Time by $23.00, which was the average 
closing price on the Nasdaq National Market for shares of Boole Common Stock 
for the five (5) trading days ending on January 8, 1997.

               (ii) Each share of MAXM's Class B preferred stock, par value 
$.01 per share, issued and outstanding immediately prior to the Effective 
Time was converted into the right to receive a fraction of a share of Boole 
Common Stock determined by dividing $3.810 plus dividends accrued from 
December 31, 1996 to the Effective Time by $23.00.

               (iii)     Each share of MAXM's Class C preferred stock, par 
value $.01 per share, issued and outstanding immediately prior to the 
Effective Time was converted into the right to receive a fraction of a share 
of Boole Common Stock determined by dividing $5.077 plus dividends accrued 
from December 31, 1996 to the Effective Time by $23.00.

               (iv) Each share of MAXM's common stock issued and outstanding 
immediately prior to the Effective Time was converted into the right to 
receive such fraction of a share of Boole Common Stock as is equal to (x) 
1,137,930 reduced by the aggregate number of shares allocated pursuant to 
subsections (i), (ii), and (iii) above, divided by (y) the number of the 
shares of MAXM's common stock outstanding immediately prior to the Effective 
Time.

All entitlements to fractional shares will be paid in cash. In addition Boole 
will pay cash to former shareholders of MAXM who exercised their appraisal 
rights under Delaware law and have accepted Boole's cash settlement offer.

     The Registrant will issue approximately 1,137,114 shares of Boole Common
Stock to former stockholders of MAXM in connection with the Merger.  Ten 
percent of these shares will be held in escrow to secure the indemnification 
obligations of MAXM and the former shareholders of MAXM under the Agreement 
pursuant the terms of an Escrow Agreement dated as of January 16, 1997.

<PAGE>

     The Merger is intended to be taxable to the shareholders of MAXM and 
will be accounted for as a pooling of interests.  A copy of the press release 
announcing the consummation of the Merger is attached hereto as Exhibit 99.1.

     MAXM develops, markets and supports client/server software solutions 
used by network and system operations management and service support.  MAXM's 
flagship product, MAX/Enterprise, is comprised of a powerful automation 
server and text and graphic clients, integral product components, a software 
development toolkit (an "SDK"), and related professional services.  These 
products and services centralize and automate the detection and correction of 
problems to increase the availability of important applications and the 
technology infrastructure that supports them.  This practice, event 
management, decreases or eliminates "downtime".

                               AGREEMENT AND PLAN
                          OF MERGER AND REORGANIZATION


     THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION ("Agreement") is 
made and entered into as of December 10, 1996, by and among:  BOOLE & 
BABBAGE, INC., a Delaware corporation ("Parent"); MINIMUM ACQUISITION SUB, 
INC., a Delaware corporation and a wholly owned subsidiary of Parent ("Merger 
Sub"); and MAXM SYSTEMS CORPORATION, a Delaware corporation (the "Company").  
Certain other capitalized terms used in this Agreement are defined in 
Exhibit A.

                                    RECITALS

     A.   Parent, Merger Sub and the Company intend to effect a merger of 
Merger Sub into the Company in accordance with this Agreement and the 
Delaware General Corporation Law (the "Merger").  Upon consummation of the 
Merger, Merger Sub will cease to exist, and the Company will become a wholly 
owned subsidiary of Parent.

     B.   The Merger is intended to constitute a transaction which is taxable 
to the Company's Shareholders.  For accounting purposes, it is intended that 
the Merger be treated as a "pooling of interests."

     C.   This Agreement has been adopted and approved by the respective 
boards of directors of Parent, Merger Sub and the Company.

     D.   Contemporaneously with the execution and delivery of this 
Agreement, certain shareholders holding voting capital stock in the Company 
are executing and delivering to Parent a shareholder agreement (a 
"Shareholder Agreement") of even date herewith substantially in the form of 
Exhibit B.

                                    AGREEMENT

     The parties to this Agreement agree as follows:


SECTION 1.     DESCRIPTION OF TRANSACTION

     1.1  MERGER OF MERGER SUB INTO THE COMPANY.  Upon the terms and subject 
to the conditions set forth in this Agreement, at the Effective Time (as 
defined in Section 1.3), Merger Sub shall be merged with and into the 
Company, and the separate existence of Merger Sub shall cease.  The Company 
will continue as the surviving corporation in the Merger (the "Surviving 
Corporation").


                                      1

<PAGE>


     1.2  EFFECT OF THE MERGER.  The Merger shall have the effects set forth in
this Agreement and in the applicable provisions of the Delaware General
Corporation Law.

     1.3  CLOSING; EFFECTIVE TIME.  The consummation of the transactions 
contemplated by this Agreement (the "Closing") shall take place at the 
offices of Cooley Godward LLP  at 10:00 a.m. on January 22, 1997, or at such 
other time and date during the period from January 1, 1997 through February 
28, 1997 as Parent may designate upon not less than five days' prior notice 
to the Company (the "Scheduled Closing Time").  (The date on which the 
Closing actually takes place is referred to in this Agreement as the "Closing 
Date.") Contemporaneously with or as promptly as practicable after the 
Closing, a certificate of merger shall be filed with the Secretary of State 
of the State of Delaware in conformity with the requirements of Sections 103 
and 251 of the Delaware General Corporation Law.  The Merger shall become 
effective at the time such certificate of merger is filed with and accepted 
by the Secretary of State of the State of Delaware (the "Effective Time").

     1.4  ARTICLES OF INCORPORATION AND BYLAWS; DIRECTORS AND OFFICERS.  
Unless otherwise determined by Parent and the Company prior to the Effective 
Time:

          (a)  the Articles of Incorporation of the Surviving Corporation shall
     be amended and restated as of the Effective Time to conform to Exhibit C;

          (b)  the Bylaws of the Surviving Corporation shall be amended and
     restated as of the Effective Time to conform to the Bylaws of Merger Sub as
     in effect immediately prior to the Effective Time; and

          (c)  the directors and officers of the Surviving Corporation
     immediately after the Effective Time shall be the individuals identified on
     Exhibit D.

     1.5  CONVERSION OF SHARES. Subject to Sections 1.8(c) and 1.9, at the 
Effective Time, by virtue of the Merger and without any further action on the 
part of Parent, Merger Sub, the Company or any shareholder of the Company, 
each outstanding preferred and common share of the Company (the "Company 
Shares") will be converted into the voting common stock of the Parent (the 
"Parent Common Stock") as follows:

          (a)  The board of directors of the Company will determine the 
aggregate value of the common stock of the Parent (the "Parent Common Stock") 
to be received in consideration of the Merger (the "Merger Shares") by 
multiplying the aggregate number of the Merger Shares by the average closing 
price on the Nasdaq National Market for the shares of the Parent Common Stock 
for the 5 trading days ending two days prior to the Effective Time (the 
"Parent Common Share Market Value"). The aggregate number of Merger Shares to 
be issued at the Effective Time shall be up to (a) 1,189,654 if the 
guaranteed amounts payable to Micromuse Plc pursuant to the agreement 
referenced in Section 5.9(b) below are reduced to zero by December 30, 1996 
or (b) 1,137,930 if such amounts are not reduced to zero by December 30, 
1996, such number of Merger Shares in both cases having taken into account 
the 3 for 2 stock split of the Parent Common Stock consummated on December 
10, 1996.


                                      2

<PAGE>


          (b)  Each share of the Company's Class A preferred stock ("Class A 
Preferred Stock"), par value $.01 per share, issued and outstanding 
immediately prior to the Effective Time shall be converted into a fraction of 
a share of Parent Common Stock determined by dividing $3.305 plus dividends 
accrued from December 31, 1996 to the Effective Time by the Parent Common 
Share Market Value.

          (c)  Each share of the Company's Class B preferred stock ("Class B 
Preferred Stock"), par value $.01 per share, issued and outstanding 
immediately prior to the Effective Time shall be converted into a fraction of 
a share of Parent Common Stock determined by dividing $3.810 plus dividends 
accrued from December 31, 1996 to the Effective Time by the Parent Common 
Share Market Value.

          (d)  Each share of the Company's Class C preferred stock ("Class C 
Preferred Stock"), par value $.01 per share, issued and outstanding 
immediately prior to the Effective Time shall be converted into a fraction of 
a share of Parent Common Stock determined by dividing $5.077 plus dividends 
accrued from December 31, 1996 to the Effective Time by the Parent Common 
Share Market Value.

          (e)  Each share of the Company's common stock issued and 
outstanding immediately prior to the Effective Time shall be converted into 
such fraction of a share of Parent Common Stock as is equal to (x) the Merger 
Shares reduced by the aggregate number of shares allocated pursuant to 
subsections (b), (c) and (d) above, divided by (y) the number of the shares 
of the Company's common stock outstanding immediately prior to the Effective 
Time.

          (f)  A portion of the Merger Shares shall be delivered into escrow and
held as specified in Section 1.8 hereof.

          (g)  If any shares of the Company's voting capital stock (the 
"Company Shares") outstanding immediately prior to the Closing Date are 
unvested or are subject to a repurchase option, risk of forfeiture or other 
condition under any applicable restricted stock purchase agreement or other 
agreement with the Company, then the shares of Parent Common Stock issued in 
exchange for such Company Shares will also be unvested and subject to the 
same repurchase option, risk of forfeiture or other condition, and the 
certificates representing such shares of Parent Common Stock may accordingly 
be marked with appropriate legends.

          (h)  The number of shares of Parent Common Stock set forth in this 
Section 1.5 take into account the 3 for 2 stock split of the Parent Common 
Stock consummated on December 10, 1996.  In the event the Parent at any time 
or from time to time declares or pays any dividend on Parent Common Stock 
payable in Parent Common Stock or in any right to acquire Parent Common 
Stock, or shall effect a further subdivision of the outstanding shares of 
Parent Common Stock into a greater number of shares of Parent Common Stock 
(by stock dividends, combinations, splits, recapitalizations and the like), 
or in the event the outstanding shares of Parent Common Stock shall be 
combined or consolidated, by reclassification or otherwise, into a lesser 
number of shares of Parent Common Stock, then the aggregate number of Merger 
Shares to be issued at the Effective Time shall be proportionately decreased 
or increased, as appropriate.

                                      3

<PAGE>


     1.6  EMPLOYEE STOCK OPTIONS AND WARRANTS.  At the Effective Time, (a) 
each stock option (a "Company Option") that is then vested and outstanding 
under the Company's 1988 Stock Option Plan and 1990 Stock Option Plan (the 
"Company Stock Plans"), may at the holder's option be exercised and (b) each 
unvested Company Option that is then outstanding under the Company Stock 
Plans which is entitled to acceleration shall be accelerated and may be 
exercised at the holder's option, in each case in accordance with the terms 
of, and to the extent permitted by, the relevant Company Stock Plan and the 
stock option agreement by which such Company Option is evidenced.  In 
addition, each company warrant (a "Company Warrant") that is then outstanding 
and entitled to be exercised may be exercised in accordance with and to the 
extent permitted by the warrant agreement by which such Company warrant is 
evidenced.  All remaining outstanding unexercised vested and unvested Company 
Options and Warrants shall be canceled in accordance with the Company Stock 
Plans and relevant warrant agreements.

     1.7  CLOSING OF THE COMPANY'S TRANSFER BOOKS.  At the Effective Time, 
holders of certificates representing shares of the Company's capital stock 
that were outstanding immediately prior to the Effective Time shall cease to 
have any rights as shareholders of the Company, and the stock transfer books 
of the Company shall be closed with respect to all shares of such capital 
stock outstanding immediately prior to the Effective Time.  No further 
transfer of any such shares of the Company's capital stock shall be made on 
such stock transfer books after the Effective Time.  If, after the Effective 
Time, a valid certificate previously representing any of such shares of the 
Company's capital stock (a "Company Stock Certificate") is presented to the 
Surviving Corporation or Parent, such Company Stock Certificate shall be 
canceled and shall be exchanged as provided in Section 1.8.

     1.8  EXCHANGE OF CERTIFICATES.

          (a)  At or promptly after the Effective Time, Parent shall cause 
its transfer agent to prepare two certificates for each holder of Company 
Shares who, taking into account Section 1.8(c) below, will receive Merger 
Shares, such certificates together representing the total number of shares of 
Parent Common Stock issuable pursuant to the Merger in respect of Company 
Shares held by such holder (the "Share Amount"), as follows:  (a) one 
certificate (the "Escrow Certificate") shall represent ten percent of such 
holder's Share Amount (rounded up to the nearest whole number of shares of 
Parent Stock), shall be in the name of State Street Bank and Trust Company of
California, N.A., as escrow agent (the "Escrow Agent"), and shall be delivered 
to the Escrow Agent as security for such holder's indemnity obligations under 
Section 9 hereof and (b) one certificate (the "Balance Certificate") shall 
represent the balance of such holder's Share Amount after deducting therefrom 
the shares of Parent Common Stock being placed in escrow hereunder.  At the 
Escrow Agent's request, one certificate may be issued in the name of the
Escrow Agent for deposit in escrow in lieu of separate Escrow Certificates.  
At and after the Effective Time, each holder shall be entitled to receive 
such holder's Balance Certificate upon delivery to Parent of a certificate or
certificates representing the full number of Company Shares held by such holder 
immediately prior to the Effective Time, together with a properly completed 
transmittal letter.  The Escrow Agent shall hold and administer the shares of 
Parent Common Stock delivered to it hereunder in accordance with the terms of 
an escrow agreement dated as of the Effective Date among Parent, the 
Shareholder Representatives (as defined there) and the Escrow Agent (the 
"Escrow Agreement"), such Escrow Agreement to be substantially in the form of 


                                      4

<PAGE>

Exhibit E attached hereto.  Until surrendered as contemplated by this Section 
1.8, each Company Stock Certificate shall be deemed, from and after the 
Effective Time, to represent only the right to receive upon such surrender a 
certificate representing shares of Parent Common Stock (and cash in lieu of 
any fractional share of Parent Common Stock) as contemplated by this Section 
1.  If any Company Stock Certificate shall have been lost, stolen or 
destroyed, Parent may, in its discretion and as a condition precedent to the 
issuance of any certificate representing Parent Common Stock, require the 
owner of such lost, stolen or destroyed Company Stock Certificate to provide 
an appropriate affidavit and to deliver a bond (in such sum as Parent may 
reasonably direct) as indemnity against any claim that may be made against 
Parent or the Surviving Corporation with respect to such Company Stock 
Certificate.

          (b)  No dividends or other distributions declared or made with 
respect to Parent Common Stock with a record date after the Effective Time 
shall be paid to the holder of any unsurrendered Company Stock Certificate 
with respect to the shares of Parent Common Stock represented thereby, and no 
cash payment in lieu of any fractional share shall be paid to any such 
holder, until such holder surrenders such Company Stock Certificate in 
accordance with this Section 1.8 (at which time such holder shall be entitled 
to receive all such dividends and distributions and such cash payment).

          (c)  No fractional shares of Parent Common Stock shall be issued in 
connection with the Merger, and no certificates for any such fractional 
shares shall be issued, provided that fractional shares resulting from the 
conversion of each class of shares held by holders of more than one class of 
shares of the Company will be aggregated before determining whether a 
fractional share remains. In lieu of such fractional shares, any holder of 
capital stock of the Company who would otherwise be entitled to receive a 
fraction of a share of Parent Common Stock (after aggregating all fractional 
shares of Parent Common Stock issuable to such holder) shall, upon surrender 
of such holder's Company Stock Certificate(s), be paid in cash the dollar 
amount (rounded to the nearest whole cent), without interest, determined by 
multiplying such fraction by the Parent Common Share Market Price.

          (d)  The shares of Parent Common Stock to be issued in the Merger 
shall be characterized as "restricted securities" for purposes of Rule 144 
under the Securities Act, and each certificate representing any of such 
shares shall, until such time that the shares are not so restricted under the 
Securities Act, bear a legend identical or similar in effect to the following 
legend (together with any other legend or legends required by applicable 
state securities laws or otherwise, if any):

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
          SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED
          UNLESS REGISTERED UNDER THE ACT OR UNLESS AN EXEMPTION FROM THE
          REGISTRATION REQUIREMENTS OF THE ACT IS AVAILABLE."

          (e)  Parent and the Surviving Corporation shall be entitled to 
deduct and withhold from any consideration payable or otherwise deliverable 
to any holder or former holder 


                                      5

<PAGE>


of capital stock of the Company pursuant to this Agreement such amounts as 
Parent or the Surviving Corporation may be required to deduct or withhold 
therefrom under the Code or under any provision of state, local or foreign 
tax law.  To the extent such amounts are so deducted or withheld, such 
amounts shall be treated for all purposes under this Agreement as having been 
paid to the Person to whom such amounts would otherwise have been paid.

          (f)  Neither Parent nor the Surviving Corporation shall be liable 
to any holder or former holder of capital stock of the Company for any shares 
of Parent Common Stock (or dividends or distributions with respect thereto), 
or for any cash amounts, delivered to any public official pursuant to any 
applicable abandoned property, escheat or similar law.

     1.9  DISSENTING SHARES.

          (a)  Notwithstanding anything to the contrary contained in this 
Agreement, any shares of capital stock of the Company that, as of the 
Effective Time, are or may become entitled to appraisal rights pursuant to 
Section 262 of the Delaware General Corporation Law shall not be converted 
into or represent the right to receive Parent Common Stock in accordance with 
Section 1.5 (or cash in lieu of fractional shares in accordance with Section 
1.8(c)), and the holder or holders of such shares shall be entitled only to 
such rights as may be granted to such holder or holders by Section 262 of the 
Delaware General Corporation Law; PROVIDED, HOWEVER, that if the appraisal 
right associated with such shares shall not be perfected, or if any such 
shares shall lose their appraisal rights then, as of the later of the 
Effective Time or the time of the failure to perfect such status or the loss 
of such status, such shares shall automatically be converted into and shall 
represent only the right to receive (upon the surrender of the certificate or 
certificates representing such shares) Parent Common Stock in accordance with 
Section 1.5 (and cash in lieu of fractional shares in accordance with Section 
1.8(c)).

          (b)  The Company shall give Parent (i) prompt written notice of any 
notice received by the Company prior to the Effective Time of a shareholder's 
intent to demand payment for such shareholder's Company Shares pursuant to 
Section 262 of the Delaware General Corporation Law  and of any other demand, 
notice or instrument delivered to the Company prior to the Effective Time 
pursuant to the Delaware General Corporation Law,  and (ii) the opportunity 
to participate in all negotiations and proceedings with respect to any such 
demand, notice or instrument.  The Company shall not make any payment or 
settlement offer prior to the Effective Time with respect to any such demand 
unless Parent shall have consented in writing to such payment or settlement 
offer.

     1.10 TAX CONSEQUENCES.  For federal income tax purposes, the Merger is 
intended to constitute a transaction which is taxable to the Company's 
shareholders.

     1.11 ACCOUNTING TREATMENT.  For accounting purposes, the Merger is 
intended to be treated as a "pooling of interests."

     1.12 FURTHER ACTION.  If, at any time after the Effective Time, any further
action is determined by Parent to be necessary or desirable to carry out the
purposes of this Agreement or to vest the Surviving Corporation or Parent with
full right, title and possession of and to all 

                                      6

<PAGE>

rights and property of Merger Sub and the Company, the officers and directors 
of the Surviving Corporation and Parent shall be fully authorized (in the 
name of Merger Sub, in the name of the Company and otherwise) to take such 
action.

deficiency or similar document received by the Company with respect to any 
Tax (other than liabilities for Taxes asserted under any such notice of 
deficiency or similar document which are being contested in good faith by the 
Company and with respect to which adequate reserves for payment have been 
established).  There are no liens for Taxes upon any of the assets of the 
Company except liens for current Taxes not yet due and payable.  The Company 
has not entered into or become bound by any agreement or consent pursuant to 
Section 341(f) of the Code.  The Company has not been, and the Company will 
not be, required to include any adjustment in taxable income for any tax

or other insurance, supplemental unemployment benefits, profit-sharing, 
pension or retirement plan, program or agreement (collectively, the "Plans")

          (b)  Except as set forth in Part 2.15(a) of the Disclosure 
Schedule, the Company does not maintain, sponsor or contribute to, and, to 
the best of the Company's knowledge, has not at any time in the six year 
period before the Closing maintained, sponsored or contributed to, any 
employee pension benefit plan (as defined in Section 3(2) of the Employee 
Retirement Income Security Act of 1974, as amended ("ERISA"), whether or not 
excluded from coverage under specific Titles or Merger Subtitles of ERISA) 
for the benefit of Employees or former Employees (a "Pension Plan").

          (c)  The Company maintains, sponsors or contributes only to those
employee welfare benefit plans (as defined in Section 3(1) of ERISA, whether or
not excluded from coverage under specific Titles or Merger Subtitles of ERISA)
for the benefit of Employees or former Employees which are described in Part
2.15(c) of the Disclosure Schedule (the "Welfare Plans"), none of which is a
multiemployer plan (within the meaning of Section 3(37) of ERISA).

          (d)  With respect to each Plan, the Company has delivered to Parent:

               (i)  an accurate and complete copy of such Plan (including all 
          amendments thereto);

               (ii) an accurate and complete copy of the annual report, if
          required under ERISA, with respect to such Plan for the last two 
          years;

               (iii)     an accurate and complete copy of the most recent

          and complete copies the most recent financial statements thereof;


                                      21

<PAGE>


               (v)  accurate and complete copies of all Contracts relating to
          such Plan, including service provider agreements, insurance contracts,
          minimum premium contracts, stop-loss agreements, investment management
          agreements, subscription and participation agreements and 
          recordkeeping agreements; and

               (vi) an accurate and complete copy of the most recent
          determination letter received from the Internal Revenue Service with
          respect to such Plan (if such Plan is intended to be qualified under
          Section 401(a) of the Code).

          (e)  The Company is not required to be, and, to the best of the 
Company's knowledge, has never been required to be, treated as a single 
employer with any other Person under Section 4001(b)(1) of ERISA or Section 
414(b), (c), (m) or (o) of the Code.  The Company has never been a member of 
an "affiliated service group" within the meaning of Section 414(m) of the 
Code.  To the best of the Company's knowledge, the Company has never made a 
complete or partial withdrawal from a multiemployer plan, as such term is 
defined in Section 3(37) of ERISA, resulting in "withdrawal liability," as 
such term is defined in Section 4201 of ERISA (without regard to subsequent 
reduction or waiver of such liability under either Section 4207 or 4208 of 
ERISA).

          (f)  The Company does not have any plan or commitment to create any 
additional Welfare Plan or any Pension Plan, or to modify or change any 
existing Welfare Plan or Pension Plan (other than to comply with applicable 
law) in a manner that would affect any Employee.

          (g)   Except as set forth in Part 2.15(g) of the Disclosure 
Schedule, no Welfare Plan provides death, medical or health benefits (whether 
or not insured) with respect to any current or former Employee after any such 
Employee's termination of service (other than (i) benefit coverage mandated 
by applicable law, including coverage provided pursuant to Section 4980B of 
the Code, (ii) deferred compensation benefits accrued as liabilities on the 
Unaudited Interim Balance Sheet, and (iii) benefits the full cost of which 
are borne by current or former Employees (or the Employees' beneficiaries)).

          (h)  To the best of the Company's knowledge, with respect to each 
of the Welfare Plans constituting a group health plan within the meaning of 
Section 4980B(g)(2) of the Code, the provisions of Section 4980B of the Code 
("COBRA") have been complied with in all material respects.

          (i)  To the best of the Company's knowledge, each of the Plans has 
been operated and administered in all material respects in accordance with 
applicable Legal Requirements, including but not limited to ERISA and the 
Code.

          (j)  Each of the Plans intended to be qualified under Section 
401(a) of the Code has received a favorable determination from the Internal 
Revenue Service, and the Company is not aware of any reason why any such 
determination letter should be revoked.

          (k)  Except as set forth in Part 2.15(k) of the Disclosure 
Schedule, neither the execution, delivery or performance of this Agreement, 
nor the consummation of the Merger or any of the other transactions 
contemplated by this Agreement, will result in any payment (including any 
bonus, golden parachute or severance payment) to any current or former 
Employee or director of the Company (whether or not under any Plan), or 
materially increase the benefits payable under any Plan, or result in any 
acceleration of the time of payment or vesting of any such benefits.

          (l)  Part 2.15(l) of the Disclosure Schedule contains a list of all 
salaried employees of the Company as of the date of this Agreement, and 
correctly reflects, in all material respects, their salaries, any other 
compensation payable to them (including compensation payable pursuant to 
bonus, deferred compensation or commission arrangements), their dates of 
employment and their positions.  The Company is not a party to any collective 
bargaining contract or other Contract with a labor union involving any of its 
Employees. All of the Company's employees are "at will" employees.

          (m)  Part 2.15(m) of the Disclosure Schedule identifies each 
Employee who is not fully available to perform work because of disability or 
other leave and sets forth the basis of such leave and the anticipated date 
of return to full service.

          (n)  To the best of the Company's knowledge, the Company is in 
compliance in all material respects with all applicable Legal Requirements 
and Contracts relating to employment, employment practices, wages, bonuses 
and terms and conditions of employment, including employee compensation 
matters.

          (o)  Except as set forth in Part 2.15(o) of the Disclosure 
Schedule, the Company has good labor relations, and the Company has no reason 
to believe that (i) the consummation of the Merger or any of the other 
transactions contemplated by this Agreement will have a material adverse 
effect on the Company's labor relations, or (ii) any of the Company's 
employees intends to terminate his or her employment with the Company.

     2.16 ENVIRONMENTAL MATTERS.  The Company is in compliance in all 
material respects with all applicable Environmental Laws, which compliance 
includes the possession by the Company of all permits and other Governmental 
Authorizations required under applicable Environmental Laws, and compliance 
with the terms and conditions thereof.  The Company has not received any 
notice or other communication (in writing or otherwise), whether from a 
Governmental Body, citizens group, employee or otherwise, that alleges that 
the Company is not in compliance with any Environmental Law, and, to the best 
of the Company's knowledge, there are no circumstances that may prevent or 
interfere with the Company's compliance with any Environmental Law in the 
future.  To the best of the Company's knowledge, no current or prior owner of 
any property leased or controlled by the Company has received any notice or 
other communication (in writing or otherwise), whether from a Government 
Body, citizens group, employee or otherwise, that alleges that such current 
or prior owner or the Company is not in compliance with any Environmental 
Law.  All Governmental Authorizations currently held by the Company pursuant 
to Environmental Laws are identified in Part 2.16 of the Disclosure Schedule. 
(For purposes of this Section 2.16: (i) "Environmental Law" means any

Company) under or based upon (i) any warranty provided by or on behalf of the 
Company, or (ii) any services performed by the Company.

     2.18 INSURANCE.  Part 2.18 of the Disclosure Schedule identifies all

that involves the Company or any of the assets owned or used by the Company 
or any Person whose liability the Company has or may have retained or 
assumed, either contractually or by operation of law; or (ii) that 
challenges, or that may have the effect of preventing, delaying, making

     3.1  SEC FILINGS; FINANCIAL STATEMENTS.

          (a)  Parent has delivered to the Company accurate and complete 
copies (excluding copies of exhibits) of each report, registration statement 
(on a form other than Form S-8) and definitive proxy statement filed by 
Parent with the SEC between September 30, 1995 and the date of this Agreement

if amended or superseded by a filing prior to the date of this Agreement, 
then on the date of such filing):  (i) each of the Parent SEC Documents 
complied in all material respects with the applicable requirements of the 
Securities Act or the Exchange Act (as the case may be); (ii) none of the 
Parent SEC Documents contained any untrue statement of a material fact or 
omitted to state a material fact required to be stated therein or necessary 
in order to make the statements therein, in the light of the circumstances 
under which they were made, not misleading; and (iii) since the date of the 
Parent's last Quarterly Report on Form 10-Q, no event has occurred which 
would have a material adverse effect on Parent's business, condition, assets, 
liability, operations, financial performance or prospects.

SEC Documents:  (i) complied as to form in all material respects with the

unaudited statements) as permitted by Form 10-Q of the SEC, and except that 
unaudited financial statements may not contain footnotes and are subject to 
year-end audit adjustments; and (iii) fairly present the consolidated 
financial position of Parent and its subsidiaries as of the respective dates 
thereof and the consolidated results of operations of Parent and its 
subsidiaries for the periods covered thereby.

SECTION 9.     INDEMNIFICATION, ETC.

     9.1  SURVIVAL OF REPRESENTATIONS, ETC.

          (a)  The representations and warranties made by the Company 
(including the representations and warranties set forth in Section 2 and the 
representations and warranties set forth in the Closing Certificate) shall 
survive the Closing and shall expire on the first anniversary of the Closing 
Date; PROVIDED, HOWEVER, that if, at any time prior to the first anniversary 
of the Closing Date, any Indemnitee (acting in good faith) delivers to any of 
the Indemnitors (as defined below) a written notice alleging the existence of 
a material inaccuracy in or a material breach of any of the representations 
and warranties made by the Company (and setting forth in reasonable detail 
the basis for such Indemnitee's belief that such an inaccuracy or breach may 
exist) and asserting a claim for recovery under Section 9.2 based on such 
alleged inaccuracy or breach, then the claim asserted in such notice shall 
survive the first anniversary of the Closing until such time as such claim is 
fully and finally resolved.  All representations and warranties made by 
Parent and Merger Sub shall terminate and expire as of the Effective Time, 
and any liability of Parent or Merger Sub with respect to such 
representations and warranties shall thereupon cease.

          (b)  The representations, warranties, covenants and obligations of 
the Company, and the rights and remedies that may be exercised by the 
Indemnitees, shall not be limited or otherwise affected by or as a result of 
any information furnished to, or any investigation made by or knowledge of, 
any of the Indemnitees or any of their Representatives, except to the extent 
such information is included in the Disclosure Schedule or any update to the 
Disclosure Schedule.

          (c)  For purposes of this Agreement, each statement or other item 
of information set forth in the Disclosure Schedule or in any update to the 
Disclosure Schedule shall be deemed to be a representation and warranty made 
by the Company.

     9.2  INDEMNIFICATION BY SHAREHOLDERS.

          (a)  From and after the Effective Time (but subject to Section 
9.1(a)), the holders of Company Shares who shall have received, or are 
entitled to receive, Parent Common Stock pursuant to Section 1 above (the 
"Indemnitors"), severally, but not jointly and severally, shall hold harmless 
and indemnify each of the Indemnitees from and against, and shall compensate 
and reimburse each of the Indemnitees for, any Damages which are directly or 
indirectly suffered or incurred by any of the Indemnitees or to which any of 
the Indemnitees may otherwise become subject (regardless of whether or not 
such Damages relate to any third-party claim) and which arise from or as a 
result of, or are directly or indirectly connected with:  (i) any material 
inaccuracy in or material breach of any representation or warranty set forth 
in Section 2 or in the Closing Certificate (without giving effect to any 
"Material Adverse Effect" or other materiality qualification or any similar 
qualification contained or incorporated directly or indirectly in such 
representation or warranty, but giving effect to any update to the Disclosure 
Schedule delivered by the Company and received by Parent prior to 5:00 pm EST 
on January 9, 1997); (ii) any material breach of any covenant or obligation 
of the Company (including the 


                                      39

<PAGE>

covenants set forth in Sections 4 and 5); or (iii) any Legal Proceeding 
relating to any inaccuracy or breach of the type referred to in clause "(i)" 
or "(ii)" above (including any Legal Proceeding commenced by any Indemnitee 
for the purpose of enforcing any of its rights under this Section 9).

          (b)  The Indemnitors acknowledge and agree that, if the Surviving 
Corporation suffers, incurs or otherwise becomes subject to any Damages as a 
result of or in connection with any inaccuracy in or breach of any 
representation, warranty, covenant or obligation such as would be subject to 
indemnification in Section 9.2(a), then (without limiting any of the rights 
of the Surviving Corporation as an Indemnitee) Parent shall also be deemed, 
by virtue of its ownership of the stock of the Surviving Corporation, to have 
incurred Damages as a result of and in connection with such inaccuracy or 
breach.

     9.3  LIMITATION OF PARENT CLAIMS.  The obligations and liabilities of 
the Indemnitors hereunder with respect to indemnification for Damages shall 
be subject to the following limitations:

          (a)  No indemnification shall be required to be made by the 
Indemnitors hereunder unless the amount of Damages exceeds $100,000 in the 
aggregate, in which case the Stockholders' indemnification obligations shall 
apply to the amount of such Parent Claims in excess of $100,000.

          (b)  All claims for indemnification pursuant to Section 9.2 hereof 
shall be brought and recovered by the Indemnitees solely by the return to 
Parent of property from the Escrow Fund.  Without limiting the generality of 
the foregoing, Parent shall not have any recourse against any Indemnitors 
individually, or any Indemnitor's assets or property, for Damages, except for 
recovery against the Escrow Fund pursuant to the terms of this Agreement and 
the Escrow Agreement.

          (c)  For purposes of determining the amount of property recoverable 
from the Escrow Fund sufficient to satisfy any claim subject to 
indemnification hereunder, the value of a share of Parent Stock shall be 
equal to the average closing price on the Nasdaq National Market for the 
shares of the Parent Common Stock for the five trading days ending; two days 
prior to the Effective Time.

          (d)  The Indemnitors and the Indemnitees acknowledge and agree that 
any distribution of property from the Escrow Fund to satisfy a claim 
hereunder shall be done so as to reduce each Indemnitor's interest in the 
Parent Common Stock in the Escrow Fund in a pro rata manner based on the 
Indemnitors' respective ownership interests in the Parent Common Stock in the 
Escrow Fund.

     9.4  EXCLUSIVE REMEDY.  The indemnification provided in this Article 9 
shall be the Indemnitees' exclusive remedy for any breach by the Company of a 
representation or warranty contained in this Agreement or any certificate or 
other writing delivered by the Company pursuant hereto or in connection 
herewith.  Notwithstanding the foregoing, nothing contained 


                                      40

<PAGE>

herein shall limit a party's rights or remedies with respect to claims 
resulting from or arising out of or willful misconduct or fraud.

     9.5  NO CONTRIBUTION.  Each Indemnitor waives, and acknowledges and 
agrees that he shall not have and shall not exercise or assert (or attempt to 
exercise or assert), any right of contribution, right of indemnity or other 
right or remedy against the Surviving Corporation in connection with any 
indemnification obligation or any other liability to which he may become 
subject under or in connection with this Agreement or the Closing Certificate.

     9.6  INTEREST.  Any Indemnitor who is required to hold harmless, 
indemnify, compensate or reimburse any Indemnitee pursuant to this Section 9 
with respect to any Damages shall also be liable to such Indemnitee for 
interest on the amount of such Damages (for the period commencing as of the 
date on which such Indemnitor first received notice of a claim for recovery 
by such Indemnitee and ending on the date on which the liability of such 
Indemnitor to such Indemnitee is fully satisfied by such Indemnitor) at a 
floating rate equal to the rate of interest publicly announced by Bank of 
Boston from time to time as its prime, base or reference rate.

     9.7  DEFENSE OF THIRD PARTY CLAIMS.  In the event of the assertion or 
commencement by any Person of any claim or Legal Proceeding (whether against 
the Surviving Corporation, against Parent or against any other Person) with 
respect to which the Indemnitors may become obligated to hold harmless, 
indemnify, compensate or reimburse any Indemnitee pursuant to this Section 9, 
Parent shall have the right, at its election, to proceed with the defense of 
such claim or Legal Proceeding on its own.  If Parent so proceeds with the 
defense of any such claim or Legal Proceeding:

          (a)  all reasonable expenses relating to the defense of such claim or
     Legal Proceeding shall be borne and paid exclusively by the Indemnitors out
     of the Escrow Fund;

          (b)  each Indemnitor shall make available to Parent any documents and
     materials in his possession or control, if any, that may be necessary to
     the defense of such claim or Legal Proceeding; and

          (c)  Parent shall have the right to settle, adjust or compromise such
     claim or Legal Proceeding with the consent of the Indemnitors' Agent (as
     defined in Section 10.1); PROVIDED, HOWEVER, that such consent shall not be
     unreasonably withheld.

Parent shall give the Indemnitors' Agent prompt notice of the commencement of 
any such Legal Proceeding against Parent or the Surviving Corporation; 
PROVIDED, HOWEVER, that any failure on the part of Parent to so notify the 
Indemnitors' Agent shall not limit any of the obligations of the Indemnitors 
under this Section 9 (except to the extent such failure materially prejudices 
the defense of such Legal Proceeding).

     9.8  EXERCISE OF REMEDIES BY INDEMNITEES OTHER THAN PARENT.  No Indemnitee
(other than Parent or any successor thereto or assign thereof) shall be
permitted to assert any 


                                      41

<PAGE>

indemnification claim or exercise any other remedy under this Agreement 
unless Parent (or any successor thereto or assign thereof) shall have 
consented to the assertion of such indemnification claim or the exercise of 
such other remedy.

SECTION 10.    MISCELLANEOUS PROVISIONS

     10.1 INDEMNITORS' AGENT.  The Indemnitors hereby irrevocably appoint 
Richard Smith as their agent for purposes of Section 9 (the "Indemnitors' 
Agent"), and Richard Smith hereby accepts his appointment as the Indemnitors' 
Agent.  Parent shall be entitled to deal exclusively with the Indemnitors' 
Agent on all matters relating to Section 9, and shall be entitled to rely 
conclusively (without further evidence of any kind whatsoever) on any 
document executed or purported to be executed on behalf of any Indemnitor by 
the Indemnitors' Agent, and on any other action taken or purported to be 
taken on behalf of any Indemnitor by the Indemnitors' Agent, as fully binding 
upon such Indemnitor.  If the Indemnitors' Agent shall die, become disabled 
or otherwise be unable to fulfill his responsibilities as agent of the 
Indemnitors, then the Indemnitors shall, within ten days after such death or 
disability, appoint a successor agent and, promptly thereafter, shall notify 
Parent of the identity of such successor. Any such successor shall become the 
"Indemnitors' Agent" for purposes of Section 9 and this Section 10.1.  If for 
any reason there is no Indemnitors' Agent at any time, all references herein 
to the Indemnitors' Agent shall be deemed to refer to the Indemnitors.

     10.2 FURTHER ASSURANCES.  Each party hereto shall execute and cause to 
be delivered to each other party hereto such instruments and other documents, 
and shall take such other actions, as such other party may reasonably request 
(prior to, at or after the Closing) for the purpose of carrying out or 
evidencing any of the transactions contemplated by this Agreement.

     10.3 FEES AND EXPENSES.  Each party to this Agreement shall bear and pay 
all fees, costs and expenses (including legal fees and accounting fees) that 
have been incurred or that are incurred by such party in connection with the 
transactions contemplated by this Agreement, including all fees, costs and 
expenses incurred by such party in connection with or by virtue of (a) the 
investigation and review conducted by Parent and its Representatives with 
respect to the Company's business (and the furnishing of information to 
Parent and its Representatives in connection with such investigation and 
review), (b) the negotiation, preparation and review of this Agreement 
(including the Disclosure Schedule) and all agreements, certificates, 
opinions and other instruments and documents delivered or to be delivered in 
connection with the transactions contemplated by this Agreement, (c) the 
preparation and submission of any filing or notice required to be made or 
given in connection with any of the transactions contemplated by this 
Agreement, and the obtaining of any Consent required to be obtained in 
connection with any of such transactions, and (d) the consummation of the 
Merger.

     10.4 ATTORNEYS' FEES.  If any action or proceeding relating to this 
Agreement or the enforcement of any provision of this Agreement is brought 
against any party hereto, the prevailing party shall be entitled to recover 
reasonable attorneys' fees, costs and disbursements (in addition to any other 
relief to which the prevailing party may be entitled).

                              SHAREHOLDER AGREEMENT

     THIS SHAREHOLDER AGREEMENT ("Agreement") is being executed and delivered 
as of December ____, 1996 by the undersigned (the "Shareholder") in favor of 
and for the benefit of BOOLE & BABBAGE, INC., a Delaware corporation 
("Parent"), and MAXM SYSTEMS CORPORATION, a Delaware corporation (the 
"Company").

                                    RECITALS

     A.   Shareholder owns the number and class of shares of the Company 
shown on the attached Exhibit A. Said shares, including any shares into which 
the shares shown on Exhibit A are converted or exchanged and any Company 
shares subsequently acquired by shareholder, are referred to in this 
Agreement as the "Shares."

     B.   Parent, MINIMUM ACQUISITION SUB., INC., a Delaware corporation and 
a wholly owned subsidiary of Parent ("Merger Sub") and the Company are 
entering into an Agreement and Plan of Merger and Reorganization of even date 
herewith (the "Reorganization Agreement"), providing for the merger of Merger 
Sub and the Company (the "Merger").

     C.   Parent has required, as a condition to entering into the 
Reorganization Agreement, that Shareholder execute and deliver this Agreement.

                                    AGREEMENT

     In order to induce Parent to enter into the Reorganization Agreement, 
and for other good and valuable consideration, Shareholder hereby agrees as 
follows:

     1.   REPRESENTATIONS AND WARRANTIES.  Shareholder represents and 
warrants to Parent as follows:

          (a)  Shareholder is the holder and beneficial owner of the Shares 
and has good and valid title to the Shares as his separate property, free and 
clear of any liens, pledges, security interests, adverse claims, equities, 
options, proxies, community property interests, charges, encumbrances or 
restrictions of any nature. The Shares are the only shares of the capital 
stock of the Company held by Shareholder. Subject to Section 3 of this 
Agreement, Shareholder has (and at all times through the date of consummation 
of the Merger will have) the ability to vote all of the Shares in accordance 
with Section 2 of this Agreement. Except as provided in Section 3 of this 
Agreement, Shareholder has not appointed or granted any proxy or entered into 
any agreement, contract, commitment or understanding with respect to any of 
the Shares.

<PAGE>


          (b)  Shareholder has the absolute and unrestricted right, power and 
capacity to execute, deliver and perform all of his obligations under this 
Agreement, the Proxy (as defined below) and all other agreements and 
documents executed and delivered or to be executed and delivered by 
Shareholder in connection with the transactions contemplated by the 
Reorganization Agreement, this Agreement, the Proxy and such other agreements 
and documents being referred to collectively in this Agreement as the 
"Transactional Agreements"). Each of the Transactional Agreements (i) has 
been (or will when executed by Shareholder be) duly and validly executed by 
Shareholder, and (ii) constitutes (or will when executed by Shareholder 
constitute) a valid and binding obligation of Shareholder, enforceable 
against Shareholder in accordance with its terms, subject to laws of general 
application relating to bankruptcy, insolvency and the relief of debtors, and 
to rules of law governing specific performance, injunctive relief and other 
equitable remedies.

          (c)  Neither the execution, delivery or performance of any of the 
Transactional Agreements, nor the consummation of the Merger or any of the 
other transactions contemplated by the Reorganization Agreement, will 
directly or indirectly: (i) result in any violation or breach of any 
agreement or other instrument to which Shareholder is a party or by which 
Shareholder or any of the Shares is bound; or (ii) result in a violation of 
any law, rule, regulation, order, judgment or decree to which Shareholder or 
any of the Shares is subject. No authorization, instruction, consent or 
approval of any person or entity is required to be obtained by Shareholder in 
connection with the execution, delivery or performance of any of the 
Transactional Agreements.

          (d)  There is no action, suit, proceeding, dispute, litigation, 
claim, complaint or investigation by or before any court, tribunal, 
governmental body, governmental agency or arbitrator pending or, to the best 
of the knowledge of Shareholder, threatened against Shareholder that 
challenges or would challenge the execution and delivery of any of the 
Transactional Agreements or the taking of any of the actions required to be 
taken by Shareholder under any of the Transactional Agreements.

          (e)  Shareholder is aware (i) that the common stock of Parent 
("Parent Common Stock") to be issued in the Merger will not be registered and 
will not be issued pursuant to a registration statement under the Securities 
Act of 1933, as amended (the "Act"), but will instead be issued in reliance 
on the exemption from registration set forth in Section 4(2) of the Act and 
in Rule 506 under the Act, and (ii) that the neither the Merger nor the 
issuance of such Parent Common Stock has been approved or reviewed by the 
Securities and Exchange Commission or by any other governmental agency.

          (f)  Shareholder is aware that, because the Parent Common Stock to 
be issued in the Merger will not be registered under the Act, such Parent 
Common Stock must be held indefinitely and such Parent Common Stock can not 
be resold unless such Parent Common Stock is registered under the Act or 
unless an exemption from registration is available. Shareholder 

<PAGE>

is also aware that: (i) except as expressly provided in the Reorganization 
Agreement and the Registration Rights Agreement executed and delivered or to 
be executed and delivered by the Company in connection with the Merger, 
Parent is under no obligation to file a registration statement with respect 
to such Parent Common Stock to be issued to him in the Merger; and (ii) the 
provisions of Rule 144 under the Act will permit resale of the Parent Common 
Stock to be issued to him in the Merger only under limited circumstances and 
that such Parent Common Stock must be held by him at least two years before 
it can be sold pursuant to Rule 144. Shareholder is further aware that any 
transfer of the Parent Common Stock he is receiving in the Merger may also be 
subject to (1) the restrictions contained in the Affiliate Agreement to be 
executed by certain Shareholders in favor of the Company.

          (g)  The Parent Common Stock to be issued Shareholder in the Merger 
will be acquired by him for investment and for his own account, and not with 
a view to, or for resale in connection with, any unregistered distribution 
thereof.

          (h)  Shareholder has requested and received, reviewed and 
considered all the information Shareholder considers necessary to enable him 
to make an informed decision to invest in Parent Common Stock, including: (i) 
a copy of Parent's report on Form 10-K for 1995; (ii) a copy of Parent's 1995 
Annual Report to Stockholders; and (iii) a copy of Parent's reports on Form 
10-Q for the last quarter of 1995 and the first two quarters of 1996 (the 
documents referred to in clauses "(i)," "(ii)," and "(iii)" of this Section 
l(h) being referred to collectively in this Agreement as the "Disclosure 
Documents").

          (i)  Shareholder confirms that he and his representatives and 
advisors have been given the opportunity: (i) to ask questions of, and to 
receive answers from, persons acting on behalf of the Company and Parent 
concerning the terms and conditions of the Merger and the contemplated 
issuance of Parent Common Stock in the Merger, and the business, properties, 
prospects and financial condition of the Company and Parent; and (ii) to 
obtain any additional information (to the extent the Company or Parent 
possesses such information or is able to acquire it without unreasonable 
effort or expense and without breach of confidentiality obligations) 
necessary to verify the accuracy of the information set forth in the 
Disclosure Documents.

          (j)  Shareholder is an "accredited investor" within the meaning of 
Rule 501(a) under the Act.

          (k)  Shareholder is knowledgeable, sophisticated and experienced in 
making, and is qualified to make, decisions with respect to investments in 
securities presenting investment decisions like that involved in 
Shareholder's contemplated investment in the Parent Common Stock to be issued 
in the Merger. Shareholder understands and has fully considered the risks of 
acquiring and owning Parent Common Stock and further understands that: (i) an 
investment in Parent Common Stock is a speculative investment which involves 
a high degree of risk and is suitable only for an investor who is able to 
bear the economic consequences of losing his entire 

                                      B-3

<PAGE>

investment; and (ii) there are substantial restrictions on the 
transferability of the Parent Common Stock to be issued in the Merger, and, 
accordingly, it may not be possible for Shareholder to liquidate his 
investment in such Parent Common Stock (in whole or in part) in the case of 
emergency. Shareholder is able: (1) to hold the Parent Common Stock for a 
substantial period of time; and (2) to afford a complete loss of his 
investment in such Parent Common Stock.

          (l)  Shareholder understands that stop transfer instructions will 
be given to Parent's transfer agent with respect to the Parent Common Stock 
to be issued to Shareholder in the Merger, and that there will be placed on 
the certificate or certificates representing such Parent Common Stock the 
following legend (together with any other legend or legends required by 
applicable state securities laws or otherwise):

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
          SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED
          UNLESS REGISTERED UNDER THE ACT OR UNLESS AN EXEMPTION FROM THE
          REGISTRATION REQUIREMENTS OF THE ACT IS AVAILABLE."

          (m)  The representations and warranties contained in this Agreement
are accurate in all respects as of the date of this Agreement, will be accurate
in all respects at all times through the consummation of the Merger and will be
accurate in all respects as of the date of the consummation of the Merger as if
made on that date.

     2.   AGREEMENT TO VOTE SHARES.  Shareholder shall vote all of the Shares at
every meeting of the shareholders of the Company (and every adjournment or
postponement of each such meeting), and (to the extent requested by Parent) by
executing a written consent in lieu of such a meeting or otherwise):

          (a)  in favor of approval of the Reorganization Agreement, the Merger,
     and the other transactions contemplated by the Reorganization Agreement;
     and

          (b)  against (i) any proposal made in opposition to or in competition
     with the consummation of the Merger, (ii) any proposal contemplating any
     transaction involving: (A) the sale, license, disposition or acquisition of
     all or a material portion of the Company's business or assets; (B) the
     issuance, disposition or acquisition of (1) any capital stock or other
     equity security of the Company, (2) any option, call, warrant or right
     (whether or not immediately exercisable) to acquire, or otherwise relating
     to, any capital stock or other equity security of the Company, or (3) any
     security, instrument or obligation that is or may become convertible into
     or exchangeable for any capital stock or other equity security of the
     Company; or (C) any merger (other than the Merger), consolidation, business
     combination, share exchange, reorganization or similar transaction
     involving the Company; and (iii) any other action or agreement that could

                                      B-4

<PAGE>

     reasonably be expected to result in a breach of any representation,
     warranty, covenant or obligation of the Company or Shareholder under any of
     the Transactional Agreements or that could reasonably be expected to result
     in any of the conditions to the Company's or Parent's obligations under the
     Reorganization Agreement not being satisfied.

Shareholder further agrees not to take any action, whether at a meeting of 
shareholders, by written consent in lieu of a meeting or otherwise: (x) to 
modify or rescind any prior action approving the Reorganization Agreement, 
the Merger or any of the other transactions contemplated by the 
Reorganization Agreement; (y) that is inconsistent with the Reorganization 
Agreement or any of the transactions contemplated thereby; or (z) that could 
reasonably be expected to result in the breach of any representation, 
warranty, covenant or obligation of the Company or Shareholder under any of 
the Transactional Agreements or that could reasonably be expected to result 
in any of the conditions to the Company's or Parent's obligations under the 
Reorganization Agreement not being satisfied.

     3.   IRREVOCABLE PROXY.  Concurrently with the execution of this 
Agreement, Shareholder shall deliver to Parent a proxy in the form attached 
hereto as Exhibit B (the "Proxy"), which shall be deemed to be coupled with 
an interest and shall be irrevocable to the extent provided in Section 212 of 
the Delaware General Corporation Law. Shareholder understands and agrees that 
such proxy shall be used by Parent in the event that Shareholder fails or is 
unable to vote the Shares in accordance with Section 2 of this Agreement.

     4.   AGREEMENT TO WAIVE REDEMPTION RIGHT.  Shareholder agrees not to 
redeem all or any part of the Shares or accumulated and unpaid dividends 
associated with the Shares, as permitted by the Company's Certificate of 
Incorporation.

     5.   AGREEMENT TO CONVERT SHARES; APPOINTMENT OF ATTORNEY-IN-FACT TO 
ACCOMPLISH CONVERSION.  Shareholder agrees to convert the number of shares of 
each class of Preferred Stock of the Company held or controlled by the 
Shareholder, as indicated on Exhibit C, to Common Stock of the Company (the 
"Conversion") as of the close of business on the record date established by 
the Board of Directors of the Company for the shareholders' meeting to 
approve the Merger (the "Conversion Date"); PROVIDED THAT, if The UpData 
Group, Inc., as financial advisor to the Company, concludes in writing to the 
Shareholder that, as of the Conversion Date and as a result of a change in 
value of the shares of Parent to be received as consideration in the Merger, 
that a revised number of shares of each class of Preferred Stock held or 
controlled by the Shareholder, as indicated in such writing, should be 
converted to Common Stock (the "Revised Conversion"), Shareholder hereby 
agrees to convert such number of shares of each class of Preferred Stock as 
indicated in the Revised Conversion. Furthermore, Shareholder does hereby 
irrevocably appoint Richard Smith as attorney-in-fact, with full power of 
substitution and resubstitution, to act on behalf of Shareholder to take any 
and all actions and to execute any and all documents in the name of and on 
behalf of Shareholder as such attorney-in-fact determines to be necessary to 
accomplish and complete the Conversion or the Revised Conversion. The 
appointment of the attorney-in-fact is coupled with an interest and will 

                                      B-5

<PAGE>

terminate on the same terms and conditions, and at the same time, as the 
Irrevocable Proxy attached hereto as Exhibit B.

     The Shareholder acknowledges and agrees that the Conversion and Revised 
Conversion are for allocating Parent Common Stock among the holders of the 
Company's capital stock following the Merger and that the total number of 
shares of Parent Common Stock to be issued to all holders in respect of the 
Merger will be the same regardless of whether the Conversion or Revised 
Conversion is applied to the shares.

     6.   CONSENT TO ESCROW OF MERGER PROCEEDS; APPOINTMENT OF SHAREHOLDERS' 
REPRESENTATIVE. Shareholder hereby acknowledges and consents to the escrow of 
ten percent of the consideration to be received in connection with the Merger 
(the "Escrow") on the terms and conditions set forth in the Escrow Agreement 
to be executed in connection with the Merger, which escrow is being 
established for the purpose of providing recourse by Parent in the event of 
claims for indemnification pursuant to the Reorganization Agreement. 
Shareholder does hereby appoint Richard Smith representative 
("Representative"), with full power of substitution, to act on behalf of 
Shareholder to take any and all actions in connection with the Escrow, 
including but not limited to contesting or compromising any matters in 
connection with, or claims for, or related to, the indemnification of Parent 
arising under the Merger Agreement. Shareholder hereby agrees to indemnify 
and hold Representative harmless in connection with any and all actions of 
Representative related to the Escrow, provided that Representative acted in 
good faith and such actions did not constitute willful malfeasance, fraud or 
gross negligence.

     7.   TRANSFER AND ENCUMBRANCE.  Shareholder agrees not to transfer, sell 
or otherwise dispose of or to pledge or otherwise encumber any of the Shares 
or to make any offer or agreement relating thereto until such time, if ever, 
as the Merger shall have occurred or the Reorganization Agreement shall have 
been validly terminated in accordance with its terms.

     8.   ADDITIONAL PURCHASES.  Shareholder agrees that any shares of the 
capital stock of the Company acquired by Shareholder on or after the date of 
this Agreement shall be subject to the terms of this Agreement to the same 
extent as if they constituted Shares.

     9.   SPECIFIC PERFORMANCE.  Shareholder agrees that in the event of any 
breach or threatened breach by Shareholder of any covenant, obligation or 
other provision contained in this Agreement, Parent shall be entitled (in 
addition to any other remedy that may be available to Parent) to (i) a decree 
or order of specific performance or mandamus to enforce the observance and 
performance of such covenant, obligation or other provision, and (ii) an 
injunction restraining such breach or threatened breach.

     10.  INDEMNIFICATION.  Without in any way limiting any of the rights or 
remedies otherwise available to Parent, Shareholder shall hold harmless and 
indemnify Parent and Parent's affiliates from and against, and shall 
compensate and reimburse Parent and Parent's affiliates

                                ESCROW AGREEMENT


     THIS ESCROW AGREEMENT is entered into as of the date written below, by 
and among the undersigned shareholder, BOOLE & BABBAGE, INC., a Delaware 
corporation ("Parent"), MAXM SYSTEMS CORPORATION, a Delaware corporation (the 
"Company"); and RICHARD SMITH (the "Shareholder Representative") as 
representative of the shareholders of the Company, all of whom are listed on 
Attachment A (the "Shareholders"); and STATE STREET BANK AND TRUST COMPANY OF 
CALIFORNIA, N.A. (the "Escrow Agent").

                                    RECITALS

     A.   Parent, MINIMUM ACQUISITION SUB., INC., a Delaware corporation and 
a wholly-owned subsidiary of Parent ("Merger Sub"), and the Company have 
entered into an Agreement and Plan of Merger Reorganization, dated December 
10, 1996 (the "Reorganization Agreement") which provides that Merger Sub will 
be merged with and into the Company (the "Merger"), with the Company being 
the surviving corporation, on the terms and conditions set forth therein, 
resulting in the Company becoming a wholly-owned subsidiary of Parent.

     B.   The Reorganization Agreement contemplates the establishment of an 
escrow arrangement to secure the indemnification and other obligations of the 
Company and the Shareholders under the Reorganization Agreement and various 
related agreements.  As a condition precedent to Parent's execution of the 
Reorganization Agreement and related agreements, Parent has required that the 
Company and the Shareholder Representatives on behalf of the Shareholders 
enter into this Agreement as set forth in Section 1.8 of the Reorganization 
Agreement; and the Company and the Shareholder Representatives on behalf of 
the Shareholders have agreed to enter into this Agreement in order to induce 
Parent to consummate the Merger.

     C.   By virtue of the Shareholders' approval of the Reorganization 
Agreement, and/or by the execution of an Affiliate Agreement, the 
Shareholders have consented to: (i) the indemnification of Parent by the 
Shareholders as set forth in Section 9.2 of the Reorganization Agreement and 
(ii) their agreement to be bound by the terms of this Escrow Agreement and to 
be a party hereto with the same force and effect as if they were a signatory 
hereto, including without limitation (x) the establishment of this escrow to 
secure the indemnification obligations to Parent under Section 9.2 of the 
Reorganization Agreement, (y) the appointment of the Shareholder 
Representatives as their representative for the purposes of this Agreement 
and as attorney-in-fact and agents for and on behalf of each of the 
Shareholders, and the taking by the Shareholder Representatives of any and 
all actions and the making of any decisions required or permitted to be taken 
or made by them under this Agreement, and (z) all of the other terms, 
conditions and limitations in this Agreement.

                                      E-1
<PAGE>

                                    AGREEMENT

     The parties to this Escrow Agreement, intending to be legally bound, 
agree as follows:

SECTION 1.     DEFINED TERMS

     Capitalized terms used and not otherwise defined in this Escrow 
Agreement shall have the meanings assigned to them in the Reorganization 
Agreement.

SECTION 2.     ESCROW

     2.1  SHARES TO BE PLACED IN ESCROW.  On the date of the Closing (the 
"Closing Date"), Parent shall issue a certificate for ten percent (10%) of 
the aggregate number of shares of the Common Stock of Parent (the "Parent 
Common Stock") to be issued in the Merger (the "Escrow Shares"), in the name 
of Escrow Agent or its nominee, evidencing the shares of the Parent Common 
Stock to be held in escrow in accordance with this Escrow Agreement.  The 
Escrow Shares shall be held as a trust fund and shall not be subject to any 
lien, attachment, trustee process or any other judicial process of any 
creditor of any party hereto.  The Escrow Agent agrees to accept delivery of 
the Escrow Shares and to hold the Escrow Shares in escrow (the "Escrow"), 
subject to the terms and conditions of this Agreement.

     2.2  INDEMNIFICATION.  The Shareholders have agreed in Section 9.2 of 
the Reorganization Agreement severally, but not jointly and severally, to 
indemnify and hold harmless each of Parent, Merger Sub and the Surviving 
Corporation from and against, and shall compensate and reimburse each of them 
for, Damages, as set forth therein.  The Escrow Shares shall be security for 
such indemnity obligation, subject to the limitations, and in the manner 
provided, in this Agreement.

     2.3  VOTING OF SHARES.  On any matter brought before the Parent 
stockholders for a vote, the Escrow Agent shall vote the Escrow Shares as 
directed by the Shareholders individually.  Each Shareholder shall have the 
right to direct the vote of the number of shares resulting from the 
multiplication of the Shareholder's percentage set forth on Attachment A by 
the total number of Escrow Shares held by the Escrow Agent on the record date 
for the vote.

     2.4  DIVIDENDS, ETC.  Any distributions of cash, securities or other 
property in respect of or in exchange for any of the Escrow Shares, other 
than distributions of capital stock of the Parent (by way of stock dividend, 
stock split or otherwise) not constituting a dividend for purposes of Section 
301 of the Code, shall be payable and distributed directly to the 
stockholders and shall not be held in the Escrow.  At the time any of the 
Escrow Shares are required to be released from the Escrow to any person 
pursuant to this Escrow Agreement, any distributions of capital stock of the 
Parent previously made in respect of such released Escrow Shares and held in 
the Escrow shall be released from the Escrow to such person.

                                      E-2
<PAGE>

     2.5  TRANSFERABILITY.  The interests of the Shareholders in the Escrow 
and in the Escrow Shares held in the Escrow shall not be assignable or 
transferable, other than by operation of law.  No transfer of any of such 
interests by operation of law shall be recognized or given effect until 
Parent shall have received written notice of such transfer.

     2.6  FRACTIONAL SHARES.  No fractional shares of Parent Common Stock 
shall be retained in or released from the Escrow pursuant to this Escrow 
Agreement. In connection with any release of shares from the Escrow, the 
Escrow Agent shall be permitted to "round down" or to follow such other 
rounding procedures as the Escrow Agent reasonably determines to be 
appropriate in order to avoid (i) retaining any fractional share in the 
Escrow or (ii) releasing any fractional share from the Escrow.

SECTION 3.     CLAIM PROCEDURES

     3.1  CLAIM NOTICE.  If Parent determines in good faith that there is or 
has been a possible inaccuracy in or breach of any representation or warranty 
made by the Company or covenant or other provision imposed on the Company and 
set forth in any of the Reorganization Agreement or related agreements, or in 
any document or instrument delivered pursuant thereto or in connection 
therewith, (collectively, the "Transactional Agreements") and if Parent is 
entitled, under the terms of the Reorganization Agreement, to make a claim 
against the Escrow with respect to such possible inaccuracy or breach, then 
Parent may deliver to both the Shareholder Representatives and the Escrow 
Agent a written notice of such possible inaccuracy or breach (a "Claim 
Notice") setting forth (i) a brief description of the circumstances 
supporting Parent's belief that such possible inaccuracy or breach exists or 
has occurred, and (ii) to the extent possible, a non-binding, preliminary 
estimate of the aggregate dollar amount of all Damages that have arisen and 
may arise as a result of such possible inaccuracy or breach (such aggregate 
amount being referred to as the "Claim Amount").  Such Claim Notice must be 
delivered prior to the date of release of the audit report for Parent's 
audited financial statements for its fiscal year ended September 30, 1997.

     3.2  RESPONSE NOTICE.  Within forty-five (45) days after the delivery of 
a Claim Notice to the Shareholder Representatives, the Shareholder 
Representatives shall deliver to Parent, with a copy to the Escrow Agent, a 
written notice (the "Response Notice") containing:  (i) instructions to the 
effect that shares of Parent Common Stock having a Stipulated Value (as 
defined in Section 6 of this Escrow Agreement) equal to the entire Claim 
Amount set forth in such Claim Notice are to be released from the Escrow to 
Parent; or (ii) instructions to the effect that shares of Parent Common Stock 
having a Stipulated Value equal to a specified portion (but not the entire 
amount) of the Claim Amount set forth in such Claim Notice are to be released 
from the Escrow to Parent, together with a statement that the remaining 
portion of such Claim Amount is being disputed; or (iii) a statement that the 
entire Claim Amount set forth in such Claim Notice is being disputed.  If no 
Response Notice is received by Parent from the Shareholder Representatives 
within forty-five (45) days after the delivery of a Claim Notice to the 
Shareholder Representatives, then the Shareholder Representatives shall be 
deemed to have given instructions that shares of Parent Common Stock having a 
Stipulated Value equal to the 

                                      E-3
<PAGE>

entire Claim Amount set forth in such Claim Notice are to be released to 
Parent from the Escrow.

     3.3  RELEASE OF SHARES TO PARENT.

          (a)  If the Shareholder Representatives give (or are deemed to have 
given) instructions that shares of Parent Common Stock having a Stipulated 
Value equal to the entire Claim Amount set forth in a Claim Notice are to be 
released from the Escrow to Parent, then the Escrow Agent shall promptly 
following the required delivery date for the Response Notice transfer, 
deliver and assign to Parent such number of Escrow Shares held in the Escrow 
as have a Stipulated Value equal to the Claim Amount (or such lesser number 
of Escrow Shares as is then held in the Escrow).

          (b)  If a Response Notice delivered by the Shareholder 
Representatives in response to a Claim Notice contains instructions to the 
effect that shares of Parent Common Stock having a Stipulated Value equal to 
a specified portion (but not the entire amount) of the Claim Amount set forth 
in such Claim Notice are to be released from the Escrow to Parent, then (i) 
the Escrow Agent shall promptly following the required delivery date for the 
Response Notice transfer, deliver and assign to Parent such number of Escrow 
Shares held in the Escrow as have a Stipulated Value equal to such specified 
portion of such Claim Amount, and (ii) the procedures set forth in Section 
3.3(c) of this Escrow Agreement shall be followed with respect to the 
remaining portion of such Claim Amount.

          (c)  If a Response Notice delivered by the Shareholder 
Representatives in response to a Claim Notice contains a statement that all 
or a portion of the Claim Amount set forth in such Claim Notice is being 
disputed (such Claim Amount or the disputed portion thereof being referred to 
as the "Disputed Amount"), then, notwithstanding anything contained in 
Section 3 of this Escrow Agreement, the Escrow Agent shall continue to hold 
in the Escrow (in addition to any other shares of Parent Common Stock 
permitted to be retained in the Escrow, whether in connection with any other 
dispute or otherwise) shares of Parent Common Stock having a Stipulated Value 
equal to 125% of the Disputed Amount.  Such shares of Parent Common Stock 
shall continue to be held in the Escrow until (i) delivery of a notice 
executed by Parent and the Shareholder Representatives setting forth 
instructions to the Escrow Agent regarding the release of such shares, or 
(ii) the Escrow Agent receives a copy of a court order containing 
instructions to the Escrow Agent regarding the release of such shares.  The 
Escrow Agent shall thereupon release shares of Parent Common Stock from the 
Escrow in accordance with the instructions set forth in such notice or order. 
 (The parties acknowledge that it is appropriate to retain more than 100% of 
the Claim Amount in the Escrow in recognition of the fact that Parent may 
have underestimated the aggregate amount of the actual and potential Damages 
arising in connection with a particular Claim Notice.)

SECTION 4.     SHAREHOLDER REPRESENTATIVES

     4.1  SHAREHOLDER REPRESENTATIVES.

          (a)  The Shareholders shall be represented hereunder by a committee

Representative is hereby empowered by each Shareholder to give and receive

resign or otherwise terminate this status as such, a successor, who shall be 
a Shareholder, shall be appointed by the remaining Shareholder 
Representatives, or, if no members of the committee remain, by the 
Shareholders.  All decisions of the Shareholder Representatives, if there be 
more than one, shall be made by a unanimous vote.  The Shareholder 
Representatives shall receive no compensation for their services.

          (c)  The Shareholders have agreed that the Shareholder 
Representatives shall not be liable to the Shareholders for any act done or 
omitted hereunder while acting in good faith and in the exercise of 
reasonable judgment.  The Shareholders have agreed to indemnify and hold the 
Shareholder Representatives harmless against any loss, liability, or expenses 
incurred by them in their capacity as such, except to the extent such loss, 
liability or expense is due to bad faith or negligent conduct.  The 
Shareholder Representatives shall be entitled to reimbursement by the 
Shareholders, pro rata to the percentages set forth opposite the names of the 
Shareholders on Attachment A hereto, for attorneys fees and other 
out-of-pocket expenses incurred by them in accordance with this Agreement.

          (d)  The Shareholders have agreed that a decision by the 
Shareholder Representatives shall constitute a decision of all of the 
Shareholders, and shall be final, binding and conclusive upon each of them.  
Parent, Merger Sub, the Company and the Escrow Agent may rely upon any act, 
decision, consent or instruction of the Shareholder Representatives as being 
the act, decision, consent or instruction of each and all of the Shareholders 
and Parent, Merger Sub, the Company and the Escrow Agent are hereby relieved 
from any liability to any person for any acts done by them in accordance with 
any act, decision, consent or instruction of the Shareholder Representatives.

SECTION 7.      FEES AND EXPENSES

     7.1  Parent agrees to pay or reimburse the Escrow Agent for legal fees 
incurred in connection with the preparation of this Agreement and to pay the 
Escrow Agent's reasonable compensation for its normal services hereunder in 
both cases in accordance with the attached fee schedule, which may be subject 
to change on an annual basis.  The Escrow Agent shall be entitled to

payment of any legal fees incurred by the Escrow Agent in connection with 
resolution of any claim by any party hereunder.  Each of (i) Parent and (ii) 
the Shareholders shall be liable for one-half (1/2) of such amounts and 
Parent shall be entitled to reimbursement from the Escrow Shares of the 
Shareholders' share of any such extraordinary expenses, if such share is paid 
by Parent.

     7.2  Except as may otherwise be provided herein, all expenses (including 
attorneys' fees) incurred by any Shareholder in connection with this 
Agreement shall be borne by such Shareholder.

     7.3  Fifteen days following the delivery of a notice in writing to the 
Escrow Agent and the Shareholder Representative by Parent in respect of 
Section 7.1 or Section 8.3, the Escrow Agent shall transfer, deliver and 
assign to Parent, in reimbursement of fees and expenses pursuant to the last 
sentence of Section 8.1 or the last sentence of Section 8.3, such number of 
Escrow Shares held in the Escrow which have a Stipulated Value equal to the 
amount to be reimbursed unless the Escrow Agent receives written notice of 
objection from the Shareholder Representative.  In the event such objection 
is received, the reimbursement claim shall be handled in accordance with 
Section 3.3(c).

SECTION 8. DUTIES OF THE ESCROW AGENT; LIMITATION OF ESCROW AGENT'S LIABILITY.

     8.1  The sole duty of the Escrow Agent, other than as herein specified, 
shall be to receive and hold the Escrow Shares, subject to disbursement in 
accordance with this Agreement, and the Escrow Agent shall be under no duty 
to determine whether Parent, the Shareholder Representatives or the 
Shareholders are complying with the requirements of this Agreement or any 
other agreement. Parent and Shareholders acknowledge and agree that the 
Escrow Agent (i) shall not be responsible for any of the agreements referred 
to herein but shall be obligated only for performance of such duties as are 
specifically set forth in this Escrow Agreement; (ii) shall not be obligated 
to take any legal or other action hereunder which might in its judgment 
involve any expense or liability unless it shall have been furnished with 
acceptable indemnification; (iii) may rely on and shall be protected in 
acting or refraining from acting upon any written notice, instruction, 
instrument, statement, request or document furnished to it hereunder and 
believed by it to be genuine and to have been signed or presented by the 
proper person, and shall have no responsibility for determining the accuracy 
thereof, and (iv) may consult counsel satisfactory to it, including house 
counsel, and the opinion of such counsel, shall be full and complete 
authorization and protection in respect of any action taken, suffered or 
omitted by it hereunder in good faith and in accordance with the opinion of 
such counsel.

     8.2  Neither the Escrow Agent nor any of its directors, officer or 
employees shall be liable to anyone for any action or omitted to be taken by 
it or any of its directors, officers or employees hereunder except in the 
case of gross negligence or willful misconduct.  Parent and Shareholders, 
jointly and severally, covenant and agree to indemnify the Escrow Agent and 
hold it harmless without limitation from and against any loss, liability or 
expense of any nature incurred by the Escrow Agent arising out of or in 
connection with this Agreement or with the administration of its duties 
hereunder, including but not limited to legal fees and other costs and 
expenses of loss, liability or expense shall be caused by the Escrow Agent's 
willful misconduct or gross negligence.  In no event shall the Escrow Agent 
be liable for indirect, punitive, special or consequential damages.

     8.3  Parent and Shareholder, jointly and severally, agree to assume any 
and all obligations imposed now or hereafter by any applicable tax law with 
respect to the payment of Escrow Funds under this Agreement, and to indemnify 
and hold the Escrow Agent harmless from and against any taxes, additions for 
late payment, interest,penalties and other expenses, that may be assessed 
against the Escrow Agent on any such payment or other activities under this 
Agreement. Parent and Shareholders undertake to instruct the Escrow Agent in 
writing with respect to the Escrow Agent's responsibility for withholding and 
other taxes, assessments or other governmental charges, certifications and 
governmental reporting in connection with its acting as Escrow Agent under 
this Agreement. Parent and Shareholders, jointly and severally, agree to 
indemnify and hold the Escrow Agent harmless from any liability on account of 
taxes, assessments or other governmental charges, including without 
limitation the withholding or deduction or the failure to withhold or deduct 
same, and any liability for failure to obtain proper certifications or to 
properly report to governmental authorities, to which the Escrow Agent may be 
or become subject in connection with or which arises out of this Agreement, 
including costs and expenses (including reasonable legal fees), interest and 
penalties.  Notwithstanding the 

                                      E-7
<PAGE>

foregoing, no distributions will be made unless the Escrow Agent is supplied 
with an original, signed W-9 form or its equivalent prior to distribution.  

     8.4  The Escrow Agent shall have no more or less responsibility or 
liability on account of any action or omission of any book-entry depository 
or subescrow agent employed by the Escrow Agent than any such book-entry 
depository or subescrow agent has to the Escrow Agent, except as to the 
extent that such action or omission of any book-entry depository or subescrow 
agent was caused by the Escrow Agent's own gross negligence or bad faith.

     8.5  As among themselves, each of (i) Parent and (ii) the Shareholders 
shall be liable for one-half (1/2) of any amounts owed to the Escrow Agent in 
satisfaction of any of the foregoing indemnification obligations and Parent 
shall be entitled to reimbursement from the Escrow Shares of the 
Shareholders' share of any such loss, liability or expense, if such share is 
paid by Parent. The provisions of paragraphs (b) and (c) shall survive 
termination of this Agreement.

SECTION 9.     GENERAL

     9.1  OTHER AGREEMENTS.  Nothing in this Escrow Agreement is intended 
to limit any of Parent's or the Shareholders' rights, or any obligation of 
any Shareholder, or of Parent under the Reorganization Agreement (or any 
agreement entered into in connection with the transactions contemplated by 
the Reorganization Agreement).

     9.2  GOVERNING LAW.  This Agreement shall be governed by and construed 
in accordance with the laws of the State of California, without giving effect 
to the conflict of laws provisions thereunder.

     9.3  ASSIGNMENT; BINDING UPON SUCCESSORS AND ASSIGNS.  No party hereto 
may assign any of its rights or obligations hereunder without the prior 
written consent of the other party hereto.  This Agreement will be binding 
upon and inure to the benefit of the parties hereto and their respective 
successors and permitted assigns.

     9.4  SEVERABILITY.  If any provision of this Agreement, or the 
application thereof, is for any reason and to any extent be invalid or 
unenforceable, the remainder of this Agreement and application of such 
provision to other persons or circumstances will be interpreted so as 
reasonably to effect the intent of the parties hereto.  The parties further 
agree to replace such void or unenforceable provision of this Agreement with 
a valid and enforceable provision that will achieve, to the greatest extent 
possible, the economic, business and other purposes of the void or 
unenforceable provision.

     9.5  COUNTERPARTS.  This Agreement may be executed in any number of 
counterparts, each of which shall be deemed to be an original and all of 
which shall constitute one and the same instrument.  This Agreement will 
become binding when one or more counterparts hereof,

individually or taken together, bear the signatures of all the parties 
reflected hereon as signatories.

be amended, and the observance of any term of this Agreement may be waived

prospectively) only by a writing signed by the party to be bound thereby; 
provided that this Agreement may be amended on behalf of all of the 
Shareholders by (i) the Shareholder Representatives or (ii) a majority in 
interest of the Shareholders. Notwithstanding any rights that may be created 
in any third party under the terms of this Agreement, no such amendment or 
waiver will require the consent of such third party to be effective.  The 
waiver by a party of any breach hereof or default in the performance hereof 
will not be deemed to constitute a waiver of any other default or any 
succeeding breach or default.

     9.7  ATTORNEYS' FEES.  Should suit be brought to enforce or interpret 
any part of this Agreement, the prevailing party will be entitled to recover, 
as an element of the costs of suit and not as damages, reasonable attorneys' 
fees to be fixed by the court (including, without limitation, costs, expenses 
and fees on any appeal).  The prevailing party will be entitled to recover 
its costs of suit, regardless of whether such suit proceeds to final judgment.

agreements and to give such further written assurances as may be reasonably 
requested by any other party to evidence and reflect the transactions 
described herein and contemplated hereby and to carry into effect the intents 
and purposes of this Agreement.

     9.11 ABSENCE OF THIRD PARTY BENEFICIARY RIGHTS.  No provisions of this 
Agreement are intended, nor will be interpreted, to provide or create any 
third party beneficiary rights or any other rights of any kind in any client, 
customer, affiliate, stockholder, partner or any party hereto or any other

Prior to the effective date of the resignation as specified in such notice, 
Parent will issue to the Escrow Agent a written instruction authorizing

Agent, the Shareholder's Representative shall be entitled to name such 
successor escrow agent.  If no successor escrow agent is named by Parent or 
the Shareholder's Representative, the Escrow Agent may apply to a court of 
competent jurisdiction for appointment of a successor escrow agent.

                      SHAREHOLDER INVESTMENT CERTIFICATION


     THIS SHAREHOLDER INVESTMENT CERTIFICATION ("Certification") is being 
executed and delivered as of the date written below, by the undersigned 
shareholder of MAXM SYSTEMS CORPORATION, a Delaware corporation (the 
"Company"), in favor of and for the benefit of BOOLE & BABBAGE, INC., a 
Delaware corporation ("Parent").

                                    RECITALS

     A.   The undersigned shareholder of the Company ("Shareholder") owns the 
number and class of shares of the voting capital stock of the Company set 
forth opposite Shareholder's name on the Shareholders List attached as 
Exhibit F to The Agreement and Plan of Merger and Reorganization, dated as of 
December 10, 1996, among Parent, Minimum Acquisition Sub., Inc., a Delaware 
corporation and a wholly owned subsidiary of Parent ("Merger Sub") and the 
Company (the "Reorganization Agreement").  Said shares are referred to in 
this Certification as the "Shares."

     B.   Pursuant to the Reorganization Agreement, it is contemplated that 
(if various conditions are satisfied) Merger Sub will merge with the Company 
(the merger of Merger Sub with the Company being referred to in this 
Certification as the "Merger").  Upon the consummation of the Merger, the 
holders of the Company's voting capital stock who do not properly perfect 
their appraisal rights are to receive shares of common stock of Parent 
("Parent Common Stock") in exchange for their shares of voting capital stock 
of the Company, and the Company is to become a wholly owned subsidiary of 
Parent.  Accordingly, it is contemplated that Shareholder will receive shares 
of Parent Common Stock in the Merger.

                                 CERTIFICATION 

     1.   REPRESENTATIONS AND WARRANTIES OF SHAREHOLDER.  Shareholder 
represents, warrants and certifies to Parent as follows:

          (a)  Shareholder is the holder and beneficial owner of the Shares 
and has good and valid title to the Shares free and clear of any liens, 
pledges, security interests, adverse claims, equities, options, proxies, 
community property interests, charges, encumbrances or restrictions of any 
nature.  The Shares are the only shares of the capital stock of the Company 
held by Shareholder.  Shareholder has the ability to vote all of the Shares 
at any meeting of the shareholders of the Company, or by written consent in 
lieu of any such meeting.  Shareholder has not appointed or granted any proxy 
or entered into any agreement, contract, commitment or understanding with 
respect to any of the Shares.

<PAGE>

          (b)  Shareholder is aware (i) that the Parent Common Stock to be 
issued to Shareholder in the Merger will not be registered and will not be 
issued pursuant to a registration statement under the Securities Act of 1933, 
as amended (the "Act"), but will instead be issued in reliance on the 
exemption from registration set forth in Section 4(2) of the Act and in Rule 
506 under the Act, and (ii) that neither the Merger nor the issuance of such 
Parent Common Stock has been approved or reviewed by the Securities and 
Exchange Commission or by any other governmental agency.  

          (c)  Shareholder is aware that, because the Parent Common Stock to 
be issued in the Merger will not be registered under the Act, such Parent 
Common Stock cannot be resold unless such Parent Common Stock is registered 
under the Act or unless an exemption from registration is available.  
Shareholder is also aware that: (i) except as expressly provided in the 
Registration Rights Agreement between Parent and the Company entered into or 
to be entered into as provided in the Reorganization Agreement, Parent is 
under no obligation to file a registration statement with respect to the 
Parent Common Stock to be issued to Shareholder in the Merger; and (ii) the 
provisions of Rule 144 under the Act will permit resale of the Parent Common 
Stock to be issued to Shareholder in the Merger only under limited 
circumstances, and such Parent Common Stock must be held by Shareholder for 
at least two years before it can be sold pursuant to Rule 144.

          (d)  The Parent Common Stock to be issued to Shareholder in the 
Merger will be acquired by Shareholder for investment and for his or her own 
account, and not with a view to, or for resale in connection with, any 
unregistered distribution thereof.

          (e)  Shareholder has received, reviewed and considered all the 
information Shareholder considers necessary to enable Shareholder to make an 
informed decision concerning whether to invest in Parent Common Stock or to 
seek appraisal rights in connection with the Merger, including:  (i) the 
Information Statement, dated January [  ], 1997; (ii) a copy of the 
Reorganization Agreement (which is included as an exhibit to said Information 
Statement);  (iii) a copy of Parent's report on Form 10-K for 1995; (iv) a 
copy of Parent's 1995 Annual Report to Stockholders; and (v) a copy of the 
Parent's preliminary proxy filed on December 27, 1996 (the documents referred 
to in clauses "(i)," "(ii)," "(iii)," "(iv)" and "(v)" of this Section 1(e) 
being referred to collectively in this Certification as the "Disclosure 
Documents"). 
 
          (f)  Shareholder acknowledges the he or she has appointed Shawn 
Miele of The Updata Group (the "Purchaser Representative") to act as his or 
her purchaser representative in connection with his or her evaluation of the 
merits and risks of the Merger and Shareholder's investment in Parent Common 
Stock. Shareholder further acknowledges that he or she has read and 
understands the Information Statement (including the Reorganization Agreement 
and the other exhibits thereto) and has had the opportunity to meet with the 
Purchaser Representative for the purpose of discussing the merits and risks 
of the Merger and his or her proposed investment in Parent Common Stock.

                                      H-2.
<PAGE>

          (g)  Shareholder has been given the opportunity: (i) to ask 
questions of, and to receive answers from, persons acting on behalf of the 
Company and Parent concerning the terms and conditions of the  Merger and the 
contemplated issuance of Parent Common Stock in the Merger, and the business, 
properties, prospects and financial condition of the Company and Parent; and 
(ii) to obtain any additional information (to the extent the Company or 
Parent possesses such information or is able to acquire it without 
unreasonable effort or expense and without breach of confidentiality 
obligations) necessary to verify the accuracy of the information set forth in 
the Disclosure Documents.

          (h)  Shareholder is knowledgeable, sophisticated and experienced in 
making, and is qualified to make, decisions with respect to investments in 
securities presenting investment decisions like that involved in 
Shareholder's contemplated investment in the Parent Common Stock to be issued 
in the Merger. Shareholder understands and has fully considered the risks of 
acquiring and owning Parent Common Stock and further understands that: (i) an 
investment in Parent Common Stock is a speculative investment which involves 
a high degree of risk and is suitable only for an investor who is able to 
bear the economic consequences of losing his or her entire investment; and 
(ii) there are substantial restrictions on the transferability of the Parent 
Common Stock to be issued in the Merger, and, accordingly, it may not be 
possible for Shareholder to liquidate his or her investment in such Parent 
Common Stock (in whole or in part) in the case of emergency.  Shareholder is 
able: (1) to hold the Parent Common Stock that he or she is to receive in the 
Merger for a substantial period of time; and (2) to afford a complete loss of 
his or her investment in such Parent Common Stock.

          (i)    Shareholder understands that stop transfer instructions will 
be given to Parent's transfer agent with respect to the Parent Common Stock 
to be issued to Shareholder in the Merger, and that there will be placed on 
the certificate or certificates representing such Parent Common Stock a 
legend identical or similar in effect to the following legend (together with 
any other legend or legends required by applicable state securities laws or 
otherwise):

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY
          NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED
          OR HYPOTHECATED UNLESS REGISTERED UNDER THE ACT OR UNLESS AN
          EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE ACT IS
          AVAILABLE."

          (j)  The representations and warranties contained in this 
Certification are accurate in all respects as of the date of this 
Certification, will be accurate in all respects at all times through the 
consummation of the Merger and will be accurate in all respects as of the 
date of the consummation of the Merger as if made on that date.

                                      H-3.
<PAGE>

     2.   RELIANCE. Shareholder acknowledges that Parent will rely on his or 
her representations, warranties and certifications set forth in Section 1 
above for purposes of determining his or her suitability as an investor in 
Parent Common Stock and for purposes of confirming the availability of an 
exemption from the registration requirements of the Act.

     3.   PROHIBITIONS AGAINST TRANSFER.  Shareholder shall not effect any 
sale, transfer or other disposition of any of the Parent Common Stock that he 
or she is to receive in the Merger unless:

          (a)  such sale, transfer or other disposition has been registered 
under the Act;

          (b)  such sale, transfer or other disposition is made in conformity 
with the requirements of Rule 144 under the Act, as evidenced by a broker's 
letter and a representation letter executed by Shareholder (satisfactory in 
form and content to Parent) stating that such requirements have been met;

          (c)  counsel reasonably satisfactory to Parent shall have advised 
Parent in a written opinion letter (satisfactory in form and content to 
Parent), upon which Parent may rely, that such sale, transfer or other 
disposition will be exempt from registration under the Act; or

          (d)  an authorized representative of the SEC shall have rendered 
written advice to Shareholder to the effect that the SEC would take no 
action, or that the staff of the SEC would not recommend that the SEC take 
action, with respect to such sale, transfer or other disposition, and a copy 
of such written advice and all other related communications with the SEC 
shall have been delivered to Parent.

                               AFFILIATE AGREEMENT


     THIS AFFILIATE AGREEMENT ("Agreement") is being executed and delivered 
as of December [  ], 1997 by the undersigned ("Affiliate") in favor of and 
for the benefit of BOOLE & BABBAGE, INC., a Delaware corporation ("Parent").

                                    RECITALS

     A.   Affiliate's relationship to MAXM SYSTEMS CORPORATION, a Delaware 
corporation (the "Company") as a shareholder, officer and/or director is 
shown on Exhibit A.

     B.   Parent, the Company and MINIMUM ACQUISITION SUB., INC., a Delaware 
corporation and a wholly owned subsidiary of Parent ("Merger Sub"), have 
entered into an Agreement and Plan of Merger and Reorganization dated as of 
December 10, 1996 (the "Reorganization Agreement"), providing for the merger 
of Merger Sub with and into the Company (the "Merger").  The Reorganization 
Agreement contemplates that, upon consummation of the Merger, (i) the 
Company's shareholders will receive shares of common stock, par value $.001 
per share, of Parent ("Parent Common Stock") in exchange for all of their 
shares of capital stock of the Company ("Company Shares"), and (ii) the 
Company will become a wholly owned subsidiary of Parent.  It is accordingly 
contemplated that Affiliate will receive shares of Parent Common Stock in the 
Merger.

     C.   Affiliate may be deemed to be an "affiliate" of the Company for 
purposes of: (i) the restrictions on resale imposed by the Securities Act of 
1933, as amended (the "Act"); and (ii) determining Parent's eligibility to 
account for the Merger as a "pooling of interests" under applicable "pooling 
of interests" accounting requirements (including Accounting Principles Board 
Opinion No. 16 and Accounting Series Releases 130 and 135, as amended, of the 
Securities and Exchange Commission (the "SEC")).

                                    AGREEMENT

     1.   REPRESENTATIONS AND WARRANTIES.  Affiliate represents and warrants 
to Parent as follows: 

          (a)  Affiliate is the holder and beneficial owner of the Company 
Shares shown on Exhibit B, and Affiliate has good and valid title to the 
Company Shares, free and clear of any liens, pledges, security interests, 
adverse claims, equities, options, proxies, charges, encumbrances or 
restrictions of any nature. 


                                     I-1-1.
<PAGE>

          (b)  Affiliate has carefully read this Agreement, and has discussed 
with counsel to the extent Affiliate felt necessary the limitations imposed 
on Affiliate's ability to sell, transfer or otherwise dispose of the Company 
Shares and the shares of Parent Common Stock that Affiliate is to receive in 
the Merger (the "Parent Shares").  Affiliate fully understands the 
limitations this Agreement places upon Affiliate's ability to sell, transfer 
or otherwise dispose of the Company Shares and the Parent Shares.

          (c)  Affiliate understands that the representations, warranties and 
covenants set forth in this Agreement will be relied upon by Parent and its 
counsel and accountants for purposes of determining Parent's eligibility to 
account for the Merger as a "pooling of interests," for purposes of 
determining whether Parent should proceed with the Merger and for various 
other purposes.

     2.   PROHIBITIONS AGAINST TRANSFER.

          (a)  Affiliate agrees that until such time as the Reorganization 
Agreement is validly terminated in accordance with Section 8 thereof, he 
shall not sell, transfer or otherwise dispose of, or reduce his interest in 
or risk relating to, any capital stock of the Company (including the Company 
Shares) except pursuant to and upon consummation of the Merger.

          (b)  Affiliate agrees that during the period from the date on which 
the Merger is consummated through the date on which financial results 
covering at least 30 days of post Merger combined operations of Parent and 
the Company have been published by Parent (within the meaning of the 
applicable "pooling of interests" accounting requirements) he shall not sell, 
transfer or otherwise dispose of, or reduce his interest in or risk relating 
to, any shares of Parent Common Stock (including the Parent Shares).

          (c)  Without limiting the generality of Section 2(b) of this 
Agreement, Affiliate shall not effect any sale, transfer or other disposition 
of any of the Parent Shares unless:

               (i)  such sale, transfer or other disposition has been 
          registered under the Act;

               (ii) such sale, transfer or other disposition is made in 
          conformity with the requirements of Rule 144 under the Act, as 
          evidenced by a broker's letter and a representation letter executed 
          by Affiliate (satisfactory in form and content to Parent) stating 
          that such requirements have been met;

               (iii)     counsel reasonably satisfactory to Parent shall have 
          advised Parent in a written opinion letter (satisfactory in form 
          and content to Parent), upon which Parent may rely, that such sale, 
          transfer or other disposition will be exempt from registration 
          under the Act; or

               (iv) an authorized representative of the SEC shall have 
          rendered written advice to Affiliate to the effect that the SEC 
          would take no action, or that the 

                                     I-1-2.
<PAGE>

          staff of the SEC would not recommend that the SEC take action, with 
          respect to such sale, transfer or other disposition, and a copy of 
          such written advice and all other related communications with the 
          SEC shall have been delivered to Parent.

     3.   STOP TRANSFER INSTRUCTIONS; LEGEND.

          Affiliate understands that the Parent Shares will be characterized 
as "restricted securities" for purposes of Rule 144 under the Act, and that 
therefore any sale, transfer or other disposition of any of the Parent Shares 
must be made in conformity with the provisions of said Rule or be registered 
under the Act.  Affiliate acknowledges and agrees that (i) stop transfer 
instructions will be given to Parent's transfer agent with respect to the 
Parent Shares, and (ii) each certificate representing any of such shares 
shall bear a legend identical or similar in effect to the following legend 
(together with any other legend or legends required by applicable state 
securities laws or otherwise):

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY
          NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED
          OR HYPOTHECATED UNLESS REGISTERED UNDER THE ACT OR UNLESS AN
          EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE ACT IS
          AVAILABLE.  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY
          BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED

          AT THE PRINCIPAL OFFICES OF BOOLE & BABBAGE, INC."

     4.   INDEPENDENCE OF OBLIGATIONS.  The covenants and obligations of 
Affiliate set forth in this Agreement shall be construed as independent of 
any other agreement or arrangement between Affiliate, on the one hand, and 
the Company or Parent, on the other.  The existence of any claim or cause of 
action by Affiliate against the Company or Parent shall not constitute a 
defense to the enforcement of any of such covenants or obligations against 
Affiliate.

     5.   SPECIFIC PERFORMANCE.  Affiliate agrees that in the event of any 
breach or threatened breach by Affiliate of any covenant, obligation or other 
provision contained in this Agreement, Parent shall be entitled (in addition 
to any other remedy that may be available to Parent) to:  (a) a decree or 
order of specific performance or mandamus to enforce the observance and 
performance of such covenant, obligation or other provision; and (b) an 
injunction restraining such breach or threatened breach.

     6.   INDEMNIFICATION.  Without in any way limiting any of the rights or 
remedies otherwise available to Parent, Affiliate shall hold harmless and 
indemnify Parent from and against, and shall compensate and reimburse Parent 
for, any loss, damage, injury, decline in

indirectly suffered or incurred at any time by Parent or any of Parent's 
affiliates or to which Parent or any of Parent's affiliates otherwise becomes 
subject and that arises from any inaccuracy in or breach of any 
representation, warranty, covenant or obligation of Affiliate contained in 
this Agreement.

     7.   OTHER AGREEMENTS.  Nothing in this Agreement shall limit any of the 
rights or remedies of Parent under the Reorganization Agreement or any 
Shareholder Agreement executed or to be executed by Shareholder in favor of

     THIS RELEASE ("Release") is being executed and delivered as of the date 
written below, by the undersigned ("Releasor") in favor of, and for the 
benefit of, MAXM SYSTEMS CORPORATION, a Delaware corporation (the 
"Corporation"), BOOLE & BABBAGE, INC., a Delaware corporation ("Parent"), and

          2.1.1 With respect to any Parent Offering which Parent proposes to 
commence after the end of the Pooling Period and prior to June 30, 1997 (an 
"Underwritten Offering"), Parent shall notify all Holders of Registrable 
Securities in writing no later than February 15, 1997 and will afford each 
such Holder an opportunity to include in such registration statement all or 
part of such Registrable Securities held by such Holder.  Each Holder 
desiring to include in any such registration statement all or any part of the 
Registrable Securities held by it shall no 

                                      L-2
<PAGE>

later than March 1, 1997 so notify Parent in writing (a "Participation 
Notice").  The right of any Holder to include its Registrable Securities in 
such registration shall be conditioned upon (i) such Holder being a 
Participating Holder (as defined in Section 2.10), (ii) such Holder's 
participation in such underwriting and the inclusion of such Holder's 
Registrable Securities in the underwriting to the extent provided herein and 
(iii) receipt by Parent of Participation Notices covering an aggregate of at 
least six hundred thousand (600,000) shares of Registrable Securities (as 
adjusted for stock splits, recapitalizations and the like) (a "Qualifying 
Commitment").  All Holders proposing to distribute their Registrable 
Securities through such underwriting shall enter into an underwriting 
agreement in customary form with the underwriter or underwriters selected for 
such underwriting by Parent.  Notwithstanding any other provision of the 
Agreement, if the underwriter determines in good faith that marketing factors 
require a limitation of the number of shares to be underwritten, the number 
of shares that may be included in the underwriting shall be allocated, first, 
to the Holders on a pro rata basis based on the total number of Registrable 
Securities held by the Holders; second, to Parent; and third, to any 
stockholder of Parent (other than a Holder) on a pro rata basis.  In no event 
will shares of any other selling stockholder be included in such registration 
which would reduce the number of shares which may be included by Holders 
without the written consent of Holders of not less than two-thirds (66 2/3%) 
of the Registrable Securities proposed to be sold in the offering.  In the 
event of any underwriter cutback, any selling stockholder which is a Holder 
of Registrable Securities and which is a partnership or corporation, the 
partners, retired partners and stockholders of such Holder, or the estates 
and family members of any such partners and retired partners and any trusts 
for the benefit of any of the foregoing persons shall be deemed to be a 
single "selling Holder", and any pro rata reduction with respect to such 
"selling Holder" shall be based upon the aggregate amount of shares carrying 
registration rights owned by all entities and individuals included in such 
"selling Holder", as defined in this sentence.  No securities excluded from 
the underwriting by reason of the underwriter's marketing limitation shall be 
included in such registration.  If any Holder disapproves of the terms of the 
underwriting, it may elect to withdraw therefrom by written notice to the 
Company and the underwriter.  The Registrable Securities so withdrawn shall 
also be withdrawn from registration.

          2.1.2  Parent shall have the right to terminate or withdraw any 
registration initiated or withdraw any registration initiated by it under 
this Section 2.1 prior to the effectiveness of such registration whether or 
not any Holder has elected to include securities in such registration.  The 
Registration Expenses of such withdrawn registration shall be borne by Parent 
in accordance with Section 2.3 hereof.  So long as the Company intends to 
proceed with any registration initiated by it under this Section 2.1, it 
shall use reasonable efforts to cause such registration to become effective 
as soon as reasonably practicable.

     2.2  SHELF REGISTRATION.   

          2.2.1     Parent shall prepare and file with the Securities and 
Exchange Commission ("SEC") one or more registration statements on Form S-3 
(or any successor to Form S-3) or any similar short-form registration 
statement pursuant to Rule 415 (or any appropriate similar rule that may be 
adopted by SEC) covering such number of the Registrable Securities as 
specified in Section 2.2.3 owned by all Holders then holding Registrable 
Securities (the "Shelf 

                                      L-3
<PAGE>

Registration").  The initial such registration statement shall be filed by 
(as applicable, the "Filing Date") and the Company shall make reasonable 
efforts to cause such registration statement to become effective not later 
than:

               (a)  May 15, 1997 if Parent has received a Qualifying 
Commitment but has not filed a registration statement for an Underwritten 
Offering prior to such date; or 

               (b)  June 1, 1997 if Parent has not received a Qualifying 
Commitment and has not filed a registration statement for an Underwritten 
Offering prior to such date; or

               (c)  June 30, 1997 otherwise.
          
          2.2.2     Notwithstanding the foregoing, Parent shall not be 
obligated to effect any such registration, qualification or compliance 
pursuant to this Section 2.1:

               (i)  if Form S-3 (or any successor or similar form) is not 
available for such offering by the Holders, or

               (ii) if Parent shall furnish to the Holders a certificate 
signed by the Chairman of the Board of Directors of Parent stating that in 
the good faith judgment of the Board of Directors of Parent, it would be 
seriously detrimental to Parent and its stockholders for such Form S-3 
Registration to be effected at such time, in which event Parent shall have 
the right to defer the filing of the Form S-3 registration statement for a 
period of not more than ninety (90) days after receipt of the request of the 
Holder or Holders under this Section 2.2, or

               (iii) prior to the end of the Pooling Period, or

               (iv)  prior to forty-five (45) days following the closing of 
an Underwritten Offering (or such longer period of time as may be requested 
by the underwriters of such offering), or

               (v)  in any particular jurisdiction in which Parent would be 
required to qualify to do business or to execute a general consent to service 
of process in effecting such registration.

          2.2.2     The number of shares that are registered under the Shelf 
Registration shall be as follows:

               (a)  in the case of a Shelf Registration made pursuant to 
Section 2.2.1(a) or 2.2.1(b), twenty-five percent (25%) of the Registrable 
Securities of each Holder shall be registered upon the effective date of the 
initial registration statement and an additional twenty-five percent (25%) of 
the Registrable Securities of each Holder shall be registered not later than 
every forty-five (45) days thereafter until all such shares have been 
registered; and

                                      L-4
<PAGE>

               (b)  in the case of a Shelf Registration made pursuant to 
Section 2.2.1(c), fifty percent (50%) of the Registrable Securities of each 
Holder shall be registered upon the effective date of the initial 
registration statement and the remaining Registrable Securities of each 
Holder shall be registered not later than forty-five (45) days thereafter.

          2.2.4     Parent shall use its best efforts to cause the Shelf 
Registration to become effective under the Act as soon as practicable 
following the Filing Date.  Subject to the requirements of the Act including, 
without limitation, requirements relating to updating through post-effective 
amendments or otherwise, Parent shall use its best efforts to keep the Shelf 
Registration continuously effective until the earlier of (i) the third 
anniversary of the Closing Date or (ii) such time as all of the Registrable 
Securities may be traded pursuant to Rule 144 under the Act by Holders who 
are not at such time affiliates of the Parent within the meaning set forth in 
Rule 144 under the Act; PROVIDED, that in the event of a Suspension Period, 
as set forth in Section 2.2.5 hereof, Parent shall extend the period of 
effectiveness of such Shelf Registration by the number of days of each such 
Suspension Period.  Parent shall use its best efforts to take such actions 
under the laws of various states as may be required to cause the resale of 
the Registrable Securities pursuant to the Shelf Registration to be lawful.

          2.2.5     Following the effectiveness of a Registration Statement 
filed pursuant to this Section, Parent may, at any time, suspend the 
effectiveness of such Registration Statement for up to 60 days, as 
appropriate (a "Suspension Period"), by giving notice to the Holders, if 
Parent shall have determined that Parent may be required to disclose any 
material corporate development which disclosure may have a material adverse 
effect on the Company. Notwithstanding the foregoing, no more than two 
Suspension Periods (i.e., 120 days) may occur in immediate succession.  The 
period of any such suspension of the Registration Statement shall be added to 
the period of time Parent agrees to keep the Registration Statement effective 
as provided in Section 2.2.4.  Parent shall use its best efforts to limit the 
duration and number of any Suspension Periods.  The Holders agree that, upon 
receipt of any notice from the Company of a Suspension Period, the Holders 
shall forthwith discontinue disposition of shares covered by such 
registration statement until the Holders (i) are advised in writing by Parent 
that the use of the applicable prospectus may be resumed, (ii) have received 
copies of a supplemental or amended prospectus, if applicable, and (iii) have 
received copies of any additional or supplemental filings which are 
incorporated or deemed to be incorporated by reference in such prospectus.

          2.2.6     The right of any Holder to include its Registrable 
Securities in a registration pursuant to this Section 2.2 shall be 
conditioned upon such Holder being a Participating Holder (as defined in 
Section 2.10).

     2.3  EXPENSES OF REGISTRATION.  Except as specifically provided herein, 
all Registration Expenses incurred in connection with any registration 
pursuant to Section 2.1 or 2.2 hereof shall be borne by Parent.  All Selling 
Expenses incurred in connection with any registrations hereunder, shall be 
borne by the holders of the securities so registered pro rata on the basis of 
the number of shares so registered.

     2.4  OBLIGATIONS OF PARENT.  Whenever required to effect the 
registration of any Registrable Securities, Parent shall, as expeditiously as 
reasonably possible:

          2.4.1     Prepare and file with the SEC a registration statement 
with respect to such Registrable Securities and use all reasonable efforts to 
cause such registration statement to become effective, and, upon the request 
of the Holders of a majority of the Registrable Securities registered 
thereunder, keep such registration statement effective for up to ninety (90) 
days or, if earlier, until the Holder or Holders have completed the 
distribution related thereto, PROVIDED, HOWEVER, that if such registration 
statement is filed pursuant to Section 2.2 hereof, the Company shall keep 
such registration statement effective for the period set forth therein.

          2.4.2     Prepare and file with the SEC such amendments and 
supplements to such registration statement and the prospectus used in 
connection with such registration statement as may be necessary to comply 
with the provisions of the Securities Act with respect to the disposition of 
all securities covered by such registration statement.

          2.4.3     Furnish to the Holders such number of copies of a 
prospectus, including a preliminary prospectus, in conformity with the 
requirements of the Securities Act, and such other documents as they may 
reasonably request in order to facilitate the disposition of Registrable 
Securities owned by them.

          2.4.4     Use all reasonable efforts to register and qualify the 
securities covered by such registration statement under such other securities 
or Blue Sky laws of such jurisdictions as shall be reasonably requested by 
the Holders, provided that Parent shall not be required in connection 
therewith or as a condition thereto to qualify to do business or to file a 
general consent to service of process in any such states or jurisdictions.

          2.4.5     In the event of any underwritten public offering, enter 
into and perform its obligations under an underwriting agreement, in usual 
and customary form, with the managing underwriter(s) of such offering.  Each 
Holder participating in such underwriting shall also enter into and perform 
its obligations under such an agreement.

          2.4.6     Notify each Holder of Registrable Securities covered by 
such registration statement at any time when a prospectus relating thereto is 
required to be delivered under the Securities Act of the happening of any 
event as a result of which the prospectus included in such registration 
statement, as then in effect, includes an untrue statement of a material fact 
or omits to state a material fact required to be stated therein or necessary 
to make the statements therein not misleading in the light of the 
circumstances then existing.

          2.4.7     Furnish, at the request of a majority of the Holders 
participating in the registration, on the date that such Registrable 
Securities are delivered to the underwriters for sale, if such securities are 
being sold through underwriters, or, if such securities are not being sold 
through underwriters, on the date that the registration statement with 
respect to such securities becomes effective, (i) an opinion, dated as of 
such date, of the counsel representing Parent for the purposes of such 
registration, in form and substance as is customarily given to 

                                      L-6
<PAGE>

underwriters in an underwritten public offering and reasonably satisfactory 
to a majority in interest of the Holders requesting registration, addressed 
to the underwriters, if any, and to the Holders requesting registration of 
Registrable Securities and (ii) a letter dated as of such date, from the 
independent certified public accountants of Parent, in form and substance as 
is customarily given by independent certified public accountants to 
underwriters in an underwritten public offering and reasonably satisfactory 
to a majority in interest of the Holders requesting registration, addressed 
to the underwriters, if any, and if permitted by applicable accounting 
standards, to the Holders requesting registration of Registrable Securities.

          2.5  DELAY OF REGISTRATION; FURNISHING INFORMATION.

          2.5.1     No Holder shall have any right to obtain or seek an 
injunction restraining or otherwise delaying any such registration as the 
result of any controversy that might arise with respect to the interpretation 
or implementation of this Section 2.

          2.5.2     It shall be a condition precedent to the obligations of 
Parent to take any action pursuant to Section 2.1 or 2.2 hereof that the 
selling Holders shall furnish to Parent such information regarding 
themselves, the Registrable Securities held by them and the intended method 
of disposition of such securities as shall be required to effect the 
registration of their Registrable Securities.

     2.6  INDEMNIFICATION.  In the event any Registrable Securities are 
included in a registration statement under Sections 2.1 or 2.2 hereof:

          2.6.1     To the extent permitted by law, Parent will indemnify and 
hold harmless each Participating Holder against any losses, claims, damages, 
or liabilities (joint or several) to which they may become subject under the 
Securities Act, the Exchange Act or other federal or state law, insofar as 
such losses, claims, damages or liabilities (or actions in respect thereof) 
arise out of or are based upon any of the following statements, omissions or 
violations (collectively a "Violation") by Parent: (i) any untrue statement 
or alleged untrue statement of a material fact contained in such registration 
statement, including any preliminary prospectus or final prospectus contained 
therein or any amendments or supplements thereto, (ii) the omission or 
alleged omission to state therein a material fact required to be stated 
therein, or necessary to make the statements therein not misleading, or (iii) 
any violation or alleged violation by Parent of the Securities Act, the 
Exchange Act, any state securities law or any rule or regulation promulgated 
under the Securities Act, the Exchange Act or any state securities law in 
connection with the offering covered by such registration statement; and 
Parent will reimburse each such Participating Holder for any legal or other 
expenses reasonably incurred by them in connection with investigating or 
defending any such loss, claim, damage, liability or action; provided 
however, that the indemnity agreement contained in this Section 2.6.1 shall 
not apply to amounts paid in settlement of any such loss, claim, damage, 
liability or action if such settlement is effected without the consent of 
Parent, which consent shall not be unreasonably withheld, nor shall Parent be 
liable in any such case for any such loss, claim, damage, liability or action 
to the extent that it arises out of or is based upon a Violation which occurs 
in reliance upon and 

                                      L-7
<PAGE>

in conformity with written information furnished expressly for use in 
connection with such registration by such Participating Holder.

          2.6.2     To the extent permitted by law, each Holder will, if 
Registrable Securities held by such Holder are included in the securities as 
to which such registration qualifications or compliance is being effected, 
indemnify and hold harmless Parent, each of its directors, its officers, and 
legal counsel and each person, if any, who controls Parent within the meaning 
of the Securities Act, any underwriter and any other Holder selling 
securities under such registration statement or any of such other Holder's 
partners, directors or officers or any person who controls such Holder, 
against any losses, claims, damages or liabilities (joint or several) to 
which Parent or any such director, officer, controlling person, underwriter 
or other such Holder, or partner, director, officer or controlling person of 
such other Holder may become subject under the Securities Act, the Exchange 
Act or other federal or state law, insofar as such losses, claims, damages or 
liabilities (or actions in respect thereto) arise out of or are based upon 
any Violation, in each case to the extent (and only to the extent) that such 
Violation occurs in reliance upon and in conformity with written information 
furnished by such Holder under an instrument duly executed by such Holder and 
stated to be specifically for use in connection with such registration; and 
each such Holder will reimburse any legal or other expenses reasonably 
incurred by Parent or any such director, officer, controlling person, 
underwriter or other Holder, or partner, officer, director or controlling 
person of such other Holder in connection with investigating or defending any 
such loss, claim, damage, liability or action if it is judicially determined 
that there was such a Violation; provided, however, that the indemnity 
agreement contained in this Section 2.6.2 shall not apply to amounts paid in 
settlement of any such loss, claim, damage, liability or action if such 
settlement is effected without the consent of the Holder, which consent shall 
not be unreasonably withheld; provided further, that in no event shall any 
indemnity under this Section 2.6 exceed the proceeds from the offering 
received by such Holder.

          2.6.3     Promptly after receipt by an indemnified party under this 
Section 2.6 of notice of the commencement of any action (including any 
governmental action), such indemnified party will, if a claim in respect 
thereof is to be made against any indemnifying party under this Section 2.6, 
deliver to the indemnifying party a written notice of the commencement 
thereof and the indemnifying party shall have the right to participate in, 
and, to the extent the indemnifying party so desires, jointly with any other 
indemnifying party similarly noticed, to assume the defense thereof with 
counsel mutually satisfactory to the parties; provided, however, that an 
indemnified party shall have the right to retain its own counsel, with the 
fees and expenses to be paid by the indemnifying party, if representation of 
such indemnified party by the counsel retained by the indemnifying party 
would be inappropriate due to actual or potential differing interests between 
such indemnified party and any other party represented by such counsel in 
such proceeding.  The failure to deliver written notice to the indemnifying 
party within a reasonable time of the commencement of any such action, if 
materially prejudicial to its ability to defend such action, shall relieve 
such indemnifying party of any liability to the indemnified party under this 
Section 2.6, but the omission so to deliver written notice to the 
indemnifying party will not relieve it of any liability that it may have to 
any indemnified party otherwise than under this Section 2.6.

                                      L-8
<PAGE>

          2.6.4  If the indemnification provided for in this Section 2.6 is 
held by a court of competent jurisdiction to be unavailable to an indemnified 
party with respect to any losses, claims, damages or liabilities referred to 
herein, the indemnifying party, in lieu of indemnifying such indemnified 
party thereunder, shall to the extent permitted by applicable law contribute 
to the amount paid or payable by such indemnified party as a result of such 
loss, claim, damage or liability in such proportion as is appropriate to 
reflect the relative fault of the indemnifying party on the one hand and of 
the indemnified party on the other in connection with the Violation(s) that 
resulted in such loss, claim, damage or liability, as well as any other 
relevant equitable considerations.  The relative fault of the indemnifying 
party and of the indemnified party shall be determined by a court of law by 
reference to, among other things, whether the untrue or alleged untrue 
statement of a material fact or the omission to state a material fact relates 
to information supplied by the indemnifying party or by the indemnified party 
and the parties' relative intent, knowledge, access to information and 
opportunity to correct or prevent such statement or omission; provided, that 
in no event shall any contribution by a Holder hereunder exceed the proceeds 
from the offering received by such Holder.

          2.6.5  The obligations of Parent and Holders under this Section 2.6 
shall survive completion of any offering of Registrable Securities in a 
registration statement.  No Indemnifying Party, in the defense of any such 
claim or litigation, shall, except with the consent of each Indemnified 
Party, consent to entry of any judgment or enter into any settlement which 
does not include as an unconditional term thereof the giving by the claimant 
or plaintiff to such Indemnified Party of a release from all liability in 
respect to such claim or litigation.  In the event any offering of 
Registrable Securities is underwritten, and the underwriting agreement 
provides for indemnification and/or contribution by Parent and the Holders 
offering securities thereunder, the indemnification and/or contribution 
obligations of Parent and the Holders hereunder shall in no event exceed the 
obligations of the parties set forth in such underwriting agreement.

     2.7  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the company 
to register Registrable Securities pursuant to this Section 2 may only be 
transferred by a Holder to (i) any "affiliate" (as defined in Rule 405 under 
the Securities Act) of such Holder or (ii) any person or entity acquiring at 
least twenty-five percent (25%) of the Registrable Securities of such Holder; 
provided, that (A) the transferor shall, within ten (10) days after such 
transfer, furnish to Parent written notice of the name and address of such 
transferee or assignee and the securities with respect to which such 
registration rights are being assigned, (B) such transferee shall promptly 
agree in writing to be subject to all restrictions set forth in this 
Agreement and (C) such transfer does not affect the treatment of the Merger 
as a "pooling of interests."

     2.8  AMENDMENT OF REGISTRATION RIGHTS.  Any provision of this Section 2 
may be amended and the observance thereof may be waived (either generally or 
in a particular instance and either retroactively or prospectively), only 
with the written consent of Parent and the Holders of at least a majority of 
the Registrable Securities.  Any amendment or waiver effected in accordance 
with this Section 2.8 shall be binding upon each Holder and Parent.  By 
acceptance of any benefits under this Section 2, Holders of Registrable 
Securities hereby agree to be bound by the provisions hereunder.

                                      L-9
<PAGE>

     2.9  AGREEMENT OF PARTICIPATING HOLDERS.  Notwithstanding anything to 
the contrary contained herein, no Holder shall have any rights under this 
Section 2 unless such Holder (i) executes a written agreement satisfactory in 
form and content to Parent, confirming that such Holder wishes to be allowed 
to sell Parent Common Stock pursuant to the respective registration 
statements under Sections 2.1 or 2.2 hereof and agrees to be bound by the 
provisions of this Section 2, and (ii) delivers such written agreement (as 
executed by such Holder) to Parent within 15 days after Parent delivers the 
form of such written agreement to such Holder.  (A Holder who so executes and 
delivers such an agreement is referred to in this Section 2 as a 
"Participating Holder.")  No Holder may sell any Parent Common Stock pursuant 
to a registration statement under Section 2.1 or 2.2 hereof unless such 
Holder is a Participating Holder and shall have notified Parent in writing, 
not less than seven nor more than 21 days prior to the sale of such shares, 
of such Participating Holder's intention to sell such shares.

SECTION 3.  MISCELLANEOUS.

     3.1  GOVERNING LAW.  This Agreement shall be governed by and construed 
under the laws of the State of California as applied to agreements among 
California residents entered into and to be performed entirely within 
California.

     3.2  SURVIVAL.  The representations, warranties, covenants, and 
agreements made herein shall survive any investigation made by any Holder and 
the closing of the transactions contemplated hereby.  All statements as to 
factual matters contained in any certificate or other instrument delivered by 
or on behalf of Parent pursuant hereto in connection with the transactions 
contemplated hereby shall be deemed to be representations and warranties by 
Parent hereunder solely as of the date of such certificate or instrument.

     3.3  SUCCESSORS AND ASSIGNS.  Except as otherwise expressly provided 
herein, the provisions hereof shall inure to the benefit of, and be binding 
upon, the successors, assigns, heirs, executors, and administrators of the 
parties hereto and shall inure to the benefit of and be enforceable by each 
person who shall be a holder of Registrable Securities from time to time; 
provided, however, that prior to the receipt by Parent of adequate written 
notice of the transfer of any Registrable Securities specifying the full name 
and address of the transferee, Parent may deem and treat the person listed as 
the holder of such shares in its records as the absolute owner and holder of 
such shares for all purposes, including the payment of dividends or any 
redemption price.

     3.4  SEVERABILITY.  In case any provision of the Agreement shall be 
invalid, illegal, or unenforceable, the validity, legality, and 
enforceability of the remaining provisions shall not in any way be affected 
or impaired thereby.

                                      L-10

     3.5  AMENDMENT AND WAIVER.

          3.5.1     Except as otherwise expressly provided, this Agreement 
may be amended or modified only upon the written consent of Parent and the 
holders of at least a majority of the Registrable Securities.

          3.5.2     Except as otherwise expressly provided, the obligations 
of Parent and the rights of the Holders under this Agreement may be waived 
only with the written consent of the holders of at least a majority of the 
Registrable Securities.

     3.6  DELAYS OR OMISSIONS.  It is agreed that no delay or omission to 
exercise any right, power, or remedy accruing to any Holder, upon any breach, 
default or noncompliance of Parent under this Agreement shall impair any such 
right, power, or remedy, nor shall it be construed to be a waiver of any such 
breach, default or noncompliance, or any acquiescence therein, or of any 
similar breach, default or noncompliance thereafter occurring.  It is further 
agreed that any waiver, permit, consent, or approval of any kind or character 
on any Holder's part of any breach, default or noncompliance under the 
Agreement or any waiver on such Holder's part of any provisions or conditions 
of this Agreement must be in writing and shall be effective only to the 
extent specifically set forth in such writing.  All remedies, either under 
this Agreement, by law, or otherwise afforded to Holders, shall be cumulative 
and not alternative.

     3.7  NOTICES.  All notices required or permitted hereunder shall be in 
writing and shall be deemed effectively given: (i) upon personal delivery to 
the party to be notified, (ii) when sent by confirmed telex or facsimile if 
sent during normal business hours of the recipient; if not, then on the next 
business day, (iii) five (5) days after having been sent by registered or 
certified mail, return receipt requested, postage prepaid, or (iv) one (1) 
day after deposit with a nationally recognized overnight courier, specifying 
next day delivery, with written verification of receipt.  All communications 
shall be sent to the party to be notified at the address as set forth on the 
signature pages hereof or Exhibit A hereto or at such other address as such 
party may designate by ten (10) days advance written notice to the other 
parties hereto.

     3.8  ATTORNEYS' FEES.  In the event that any dispute among the parties 
to this Agreement should result in litigation, the prevailing party in such 
dispute shall be entitled to recover from the losing party all fees, costs
