             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

1.   INTERIM FINANCIAL DATA

     The interim condensed consolidated financial statements of Consilium, Inc.
     and its subsidiaries ("the Company") are unaudited but reflect, in the
     opinion of management, all normal recurring adjustments necessary to
     present fairly the financial information set forth therein. These interim
     condensed consolidated financial statements should be read in conjunction
     with the audited financial statements and notes thereto included in the
     Company's annual report on Form 10-K for the year ended October 31, 1996.
     The Company believes the results of operations and cash flows for the three
     months ended January 31, 1997 are subject to fluctuation and are not
     necessarily indicative of results of operations and cash flows for any
     future period.

2.   NET INCOME (LOSS) PER SHARE

     Net income per common share is computed using the weighted average number
     of common and dilutive common equivalent shares outstanding during the
     period. Dilutive common equivalent shares consist of the dilutive effect of
     stock options as computed using the treasury stock method. Net loss per
     share is based on the weighted average number of common shares outstanding
     during the period. Common equivalent shares have not been included in the
     calculation of loss per share as their inclusion would be antidilutive.

3.   NOTE PAYABLE

     The Company's promissory note with a bank requires the maintenance of
     certain financial covenants, including minimum net worth and profitability
     requirements. At January 31, 1997, the Company was not in compliance with
     certain financial covenants. The Company has not obtained a waiver from the
     bank, and, as such, the loan is immediately callable by the bank.
     Accordingly, the Company has classified the remaining balance on the note
     payable as a current liability. On January 28, 1997, the Company obtained a
     commitment letter from another bank, subject to definitive agreements, for
     a secured line of credit of $6 million and an additional loan of
     approximately $2 million. However, due to the financial results of the
     current quarter, that bank withdrew its commitment to the Company. The
     bank holding the promissory note notified the Company on March 10, 1997
     with a letter dated March 3, 1997, that it has required the Company to
     either cash collateralize or pay-off the loan of approximately $1.6
     million by March 15, 1997. As of the filing date of this Form 10-Q, the
     Company has not paid off the promissory note and the Company is in
     discussions with that bank to develop a plan to pay-off the note.

                                       6
<PAGE>

     On March 14, 1997, the Company received a commitment letter from another
     bank, subject to the negotiation and execution of definitive agreements
     for a secured line of credit of $3 million. The Company plans to use a
     portion of the line of credit to pay-off the remaining balance of the
     above mentioned promissory note. The Company expects to enter into a
     definitive agreement and receive funding within the next month. If the
     Company does not receive funding pursuant to this loan commitment, the
     Company believes that it will be able, within the next month, to obtain
     the necessary funds to pay-off the balance owing on the promissory note
     either by obtaining alternative loan financing, sales leaseback financing
     or sale of accounts receivable, the latter two which may require the
     consent of the bank holding the promissory note.
 
4.   NEW ACCOUNTING PRONOUNCEMENTS

     Effective November 1, 1996, the Company adopted the disclosure only
     provisions of Statement of Financial Accounting Standards ("SFAS") No. 123,
     "Accounting for Stock-Based Compensation". The effect on the Company's
     financial position and results of operations, upon adoption, was not
     significant.

     Also effective November 1, 1996, the Company adopted the provisions of SFAS
     No. 121, "Accounting for the Impairment of Long-Lived Assets and Long-Lived
     Assets to be Disposed of." The adoption of this new pronouncement did not
     have any effect on the Company's financial position or results of
     operations.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
            ---------------------------------------------------------------
            RESULTS OF OPERATIONS
            ---------------------

This discussion contains, in addition to historical information, forward-looking
statements that involve risks and uncertainties, including statements regarding
expected development revenues, expected revenue from systems integration
projects, market acceptance of the Company's products, demand for the Company's
products in its target industries, incurrence of research and development
expenses, and competition.  The Company's actual results could differ
significantly from the results discussed in the forward-looking statements in
the section entitled "Potential Fluctuations in Quarterly Results".  Factors
that could cause or contribute to such differences include, among others, those
discussed below as well as those discussed in the Company's Annual Report on
Form 10-K for the year ended October 31, 1996.  The following discussion should
be read in conjunction with the consolidated financial statements and notes
thereto.

RESULTS OF OPERATIONS
- ---------------------


REVENUES.  Total revenues for the first quarter of fiscal 1997 decreased 6% to

$8,574,000 compared with $9,159,000 in the first quarter of fiscal 1996. The
decrease was primarily due to lower product revenues from the Company's
WorkStream/R/ and FlowStream/R/ product lines, partially offset by higher
services revenues associated with the Company's systems integration services
business.

     Total revenues for the three months ended January 31, 1997 and 1996 by
geographic region were as follows:

</TABLE>

     The increase in sales to Asia/Pacific during the first quarter of fiscal
1997 was primarily due to higher levels of sales in the Company's systems
integration services business in the Asia/Pacific region.
 
     Total revenues for the three months ended January 31, 1997 and 1996 by
product line were as follows:

     The Company's WorkStream DFS/TM/ product line is targeted at manufacturers
who produce their products in discrete lots or batches, particularly those in
the semiconductor and electronics industries. The Company's FlowStream/R/
product line is targeted at regulated or complex industries that employ batch
process manufacturing, particularly those in the healthcare products
(pharmaceutical, medical device and biotechnology), chemical and other process
industries.

Product Revenues.  Product revenues for the three months ended January 31, 1997
- ----------------                                                               
decreased 62% over the same period of the previous year.  The 1997 first fiscal
quarter decrease was primarily due to lower revenue levels from the Company's
WorkStream DFS and FlowStream product lines.
 
     Product revenues attributable to products in the Company's WorkStream DFS
product line decreased 61% to $1,761,000 during the three months ended January
31, 1997 as compared with $4,539,000 in the previous year quarter. The decrease
was primarily due to fluctuations in timing of new orders for WorkStream/R/ from
new semiconductor fabrications.
 
     Product revenues attributable to FlowStream decreased 76% to $58,000 during
the three months ended January 31, 1997 as compared with $243,000 for the same
period in fiscal 1996.  The decrease was primarily attributable to fluctuations
in the size and timing of orders for FlowStream software from the healthcare
products and process industries.  The Company expects to continue to see such
fluctuations in revenue until there is a higher level of acceptance of the
FlowStream product.  Due to the continuing fluctuations in revenue and related
delays in market acceptance, the Company announced on February 20, 1997 that it
had instituted plans to reduce the overall level of expenses related to the
FlowStream product during fiscal 1997.
 
Services Revenues.  Services revenues for the three months ended January 31,
- -----------------                                                           
1997 increased 69% to $6,634,000, compared with $3,931,000 for the same period
of fiscal 1996. Services revenues are derived primarily from systems integration
services relating to the WorkStream DFS product line, annual software
maintenance fees, specialized programming services, resident and application
consulting services and customer training.  The increase in services revenues
for the three months ended January 31, 1997 was primarily due to significantly
higher revenue levels from the Company's systems integration services business.
The Company anticipates that services revenues in fiscal 1997 will increase from
prior year levels due to higher services revenues associated with systems
integration services.  Services revenues normally are subject to fluctuation
primarily due to the timing of new contracts and the completion of existing
projects.

Development Revenues.  Development revenues for the three months ended January
- ---------------------                                                         
31, 1997 decreased 73% to $120,000, compared with $446,000 for the same period
of fiscal 1996.  Development revenues include work associated with porting
agreements and development contract work for third parties.  Under these
contracts and agreements, the Company earns development and porting revenues,
with participating third parties having the right to license and use the
software, often sooner than otherwise would have occurred.  Development revenues
can vary significantly from period to period, depending upon the number of
contracts which have been entered into and the state of completion of such
projects.  It is difficult to accurately forecast the level of development
revenues beyond the near term due to the timing and scope of development
projects that may be changed during the period of development.  Based on current
internal development resource allocations and projects planned, the Company
expects that development revenues in fiscal 1997 will decrease significantly
from prior year levels, although the Company may take on additional development
projects in the future if business and strategic objectives of the Company are
met by such projects.

COSTS AND EXPENSES
- ------------------

Cost of Product Revenues.  Cost of product revenues for the three months ended
- -------------------------                                                     
January 31, 1997 increased 10% to $796,000, compared with $721,000 for the same
period of the previous fiscal year. Cost of product revenues includes
amortization of capitalized software development costs, royalties, and purchased
software which is resold to the end customer, typically along with the Company's
own software.  Depending on the mix of sales of proprietary software (and the
variance in associated third party royalties) and additional third party
software relating to specific orders, the associated costs of product revenue
can vary significantly.  Product costs as a percentage of product revenue for
the three months ended January 31, 1997 were 44% compared with 15% for the same
period of the previous year. The increase in absolute dollars and percentage of
cost of product revenues was primarily due to higher third party costs
associated with three orders in the first quarter of fiscal 1997.
 
Cost of Services Revenues. Cost of services revenues increased 202% to
- --------------------------                                            
$4,101,000 for the three months ended January 31, 1997 compared with $1,359,000
for the same period of the previous fiscal year.  Services costs include costs
associated with systems integration services and expenses for the customer
response center, resident and application consulting services, specialized
programming services, and training groups within the Company.  Cost of services
revenues represented 62% of total services revenues for the three months ended
January 31, 1997, compared with 35% in the comparable period of fiscal 1996. The
increase in absolute dollars and percentage of cost of services revenues was
primarily due to the hiring of additional services personnel, both permanent and
sub-contracted, to enhance the Company's ability to meet customer requirements
for systems integration services, customer support and consulting services.

Cost of Development Revenues.  Cost of development revenues was 98% of total
- ----------------------------                                                
development revenues for the three months ended January 31, 1997, compared with
73% in the comparable period of fiscal 1996.  The increase in cost of
development as a percentage of development revenues primarily was due to
relatively high development costs associated with the development projects
during the three months ended January 31, 1997.  Development costs include
direct labor costs associated with development contracts and porting projects as
well as third party consulting expenses.  Development costs decreased 64% to
$117,000 for the three month period ended January 31, 1997 compared with
$327,000 for the same period of the previous fiscal year.  The decrease was
primarily due to a decrease in development revenues.

Research and Development Expenses.  Research and development expenses were 38%
- ---------------------------------                                             
of total revenues for the three month period ended January 31, 1997 compared
with 27% for the same period of the previous fiscal year.  These expenses
increased to $3,232,000 in the first fiscal quarter compared with $2,479,000 in
the same quarter of the previous fiscal year.  The increase in the percentage
and absolute dollar amount of research and development expenses in the recent
three month period compared with the same quarter last year was due to a
decrease in software development costs eligible for capitalization and hiring of
additional research and development personnel primarily to add computing
platform options and functional enhancements for the Company's products.
Included in research and development expenses are costs associated with the
development of new products and the costs of enhancing and maintaining existing
products.

    Software development expenditures of $134,000 and $286,000 were capitalized
for the three months ended January 31, 1997 and 1996, respectively.  The amounts
represented approximately 4% and 12% of total research and development
expenditures during such periods. The percentage 

                                       10
<PAGE>
 
decrease was due to a decline in the absolute dollar amount of software
development costs eligible for capitalization during the first quarter of fiscal
1997 coupled with a higher level of overall research and development
expenditures. In accordance with SFAS No. 86, the amount of research and
development expenditures capitalized in a given time period depends upon the
amount of development work performed subsequent to the establishment of
technological feasibility for a product. Accordingly, amounts capitalized may
vary from period to period.
 
Selling and Marketing Expenses.  Selling and marketing expenses represented 39%
- -------------------------------                                                
and 33% of total revenues for the three months ended January 31, 1997 and 1996,
respectively.  Selling and marketing expenses increased to $3,345,000 for the
three months ended January 31, 1997 compared with $3,029,000 for the same period
of the previous fiscal year.  The increase in the percentage and absolute dollar
amount of selling and marketing expenses in the first quarter of fiscal 1997 was
primarily due to an increase in headcount, related travel expenses and higher
allocated expenses.
 
General and Administrative Expenses.  General and administrative expenses
- ------------------------------------                                     
represented 10% of total revenues for the three months ended January 31, 1997
and 1996. General and administrative expenses include the costs of the finance,
accounting and administrative operations of the Company. General and
administrative expenses decreased to $888,000 for the three months ended January
31, 1997 compared with $920,000 for the same period of the previous fiscal year.
The higher general and administrative expenses in the first quarter of fiscal
1996 was primarily due to the moving costs associated with the relocation of the
Company's headquarters in February 1996.
 
Interest Income and Expense.  For the three months ended January 31, 1997,
- ----------------------------                                              
interest income was $61,000, compared with $146,000 for the same period of the
previous fiscal year.  Lower invested cash balances and slightly lower interest
rate levels accounted for the decrease.  Interest expense was $36,000 and $0 for
the three month periods ended January 31, 1997 and 1996, respectively.  The
increase in interest expense for the first quarter of fiscal 1997 was primarily
due to interest on a $2,000,000 promissory note obtained from a bank in April
1996.
 
Provision for Income Taxes. The income tax provision for the three months ended
- --------------------------                                                     
January 31, 1997 and 1996 represents taxes on earnings of certain foreign
subsidiaries, which are profitable, and taxes withheld on sales made in certain
foreign jurisdictions.  The effective tax rate for the first quarter of fiscal
1997 was 16%, compared with 53% for the first quarter of fiscal 1996.  The
Company has established a valuation allowance against its deferred tax asset and
reviews this allowance on a periodic basis.  At such time that the Company
believes that it is more likely than not that a portion of the deferred tax
asset will be realized, the valuation allowance will be reduced.

 
 
POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS.  The Company's results of
- -------------------------------------------                           
operations historically have fluctuated on a quarterly basis due to numerous
factors.  These factors may include: the relatively high average selling price
of the Company's products; a relatively small number of transactions; the size
and timing of new orders; market acceptance of new products; introduction of
competitive product offerings and subsequent deferrals in sales orders as
competitive products are evaluated by prospective customers;  the timing of co-
development projects with customers; expense levels; pricing changes; gain or
loss of significant customers or distributors; and 

                                       11
<PAGE>
 
the general economic conditions in the Company's primary markets. Results could
be negatively affected if the semiconductor industry slowed its expansion, or if
the healthcare products and process industries, which have not yet adopted
computer automated manufacturing on a wide scale, do not develop into a strong
market for the Company's FlowStream product line, or if the Company is
unsuccessful in managing systems integration projects profitably. Any
unfavorable change in these or other factors could have a material adverse
effect on the Company's operating results for a particular quarter. The
operating results in any quarter are not necessarily indicative of results for
future financial periods.


LIQUIDITY AND CAPITAL RESOURCES.  As of January 31, 1997, the Company had
- --------------------------------                                         
$5,027,000 in cash and cash equivalents, as compared with $9,094,000 in cash and
cash equivalents and short term investments at October 31, 1996.  The Company
used $3,443,000 for operating activities during the three months ended January
31, 1997 compared with $1,051,000 used for operating activities in the same
period of the previous fiscal year.  Net cash used for operating activities for
the three months ended January 31, 1997 of $3,443,000 primarily resulted from
the net loss of $3,942,000.

     Net cash provided by investing activities was $574,000 during the first
quarter of fiscal 1997 which represented sales of short term investments of
$1,000,000, offset by capital expenditures and capitalized software development
costs of $292,000 and $134,000, respectively.

     Net cash used for financing activities was $125,000 during the first
quarter of fiscal 1997 which represented principal payments on the $2,000,000
promissory note.

     Under the asset purchase agreement of the Taiwan operations of Systematic
Designs International, Inc., the Company may be required to make additional
annual performance-based payments (in cash or stock) over a two-year period
ending on July 8, 1998.  Such performance-based payments will be based upon a
specified percentage, ranging from 17.5% to 50.0%, of certain revenues, as
defined in the purchase agreement.
 
     The Company's promissory note with a bank requires the maintenance of
certain financial covenants, including minimum net worth and profitability
requirements.  At January 31, 1997, the Company was not in compliance with 
certain covenants. The Company has not obtained a waiver from the bank, and, as
such, the loan is immediately callable by the bank. Accordingly, the Company has
classified the remaining balance on the note payable as a current liability. On
January 28, 1997, the Company obtained a commitment letter from another bank,
subject to definitive agreements for a secured line of credit of $6 million and
an additional loan of approximately $2 million. However, due to the financial
results of the current quarter, that bank withdrew its commitment to the
Company. The bank holding the promissory note notified the Company on March 
10, 1997 with a letter dated March 3, 1997, that it has required the Company 
to either cash collateralize or pay-off the loan of approximately $1.6 million
by March 15, 1997. As of the filing date of this Form 10-Q, the Company has 
not paid off the promissory note and the Company is in discussions with that 
bank to develop a plan to pay-off the note.

                                       12
<PAGE>

     On March 14, 1997, the Company received a commitment letter from another 
bank, subject to the negotiation and execution of definitive agreements for a 
secured line of credit of $3 million. The Company plans to use a portion of the 
line of credit to pay-off the remaining balance of the above mentioned 
promissory note. The Company expects to enter into a definitive agreement and 
receive funding within the next month. If the Company does not receive funding 
pursuant to this loan commitment, the Company believes that it will be able, 
within the next month, to obtain the necessary funds to pay-off the balance 
owing on the promissory note either by obtaining alternative loan financing, 
sales leaseback financing or sale of accounts receivable, the latter two which 
may require the consent of the bank holding the promissory note.

     Management believes the existing cash and cash equivalents combined with 
its borrowing capacity and cash generated from operations will be sufficient to
meet the Company's working capital and capital expenditure requirements for at
least the next twelve months.

                                CONSILIUM, INC.

                          CHANGE OF CONTROL AGREEMENT
                          ---------------------------

     This Change of Control Agreement (the "Agreement") is effective as of
December 11, 1996, by and between Laurence R. Hootnick (the "Employee"), and
Consilium, Inc., a Delaware corporation (the "Company").


                                    RECITALS

     A.   The Employee presently serves at the pleasure of the Board of
Directors as President and Chief Executive Officer of the Company and performs
significant strategic and management responsibilities necessary to the continued
conduct of the Company's business and operations.

     B.   The Board of Directors of the Company (the "Board") has determined
that it is in the best interests of the Company and its stockholders to assure
that the Company will have the continued dedication and objectivity of the
Employee, notwithstanding the possibility or occurrence of a Change of Control
(as defined below) of the Company.

     C.   The Board believes that it is imperative to provide the Employee with
certain severance benefits upon the Employee's termination of employment
following a Change of Control which provide the Employee with enhanced financial
security and provide sufficient incentive and encouragement to the Employee to
remain with the Company following a Change of Control.

     D.   Certain capitalized terms used in the Agreement are defined in Section
3 below.

     In consideration of the mutual covenants herein contained, and in
consideration of the continuing employment of Employee by the Company, the
parties agree as follows:

     1.   Term of Employment.  The Company and the Employee agree that the
          ------------------                                              
Employee's employment is at will, and that their employment relationship may be
terminated by either party at any time, with or without cause.  If the
Employee's employment terminates for any reason, the Employee shall not be
entitled to any payments, benefits, damages, awards or compensation other than
as provided by this Agreement.  The provisions of this Agreement shall terminate
on December 31, 2001, (except that the Employee's employment by the Company
shall continue to be "at will"), unless a Change of Control occurs on or prior
to that date, in which case the provisions of this Agreement shall terminate
upon the earlier to occur of (i) the date that all obligations of the parties
hereunder have been satisfied, or (ii) twelve (12) 

                                       1
<PAGE>
 
months after the Change of Control. Any termination of this Agreement shall not
affect any required payment or benefit that accrues prior to such termination.

     2.   Severance Benefits.  Subject to Sections 2(d) and 2(e) below,
          ------------------                                           

          (a)  Termination Following A Change of Control.  If the Employee's
               -----------------------------------------                    
employment is terminated within twelve (12) months following a Change of
Control, then the Employee shall be entitled to receive severance benefits as
follows:

               (i)  Involuntary Termination.  If the Employee's employment is
                    -----------------------                                  
terminated as a result of Involuntary Termination (as defined in Section 3(b)
below), then the Employee shall be entitled to receive severance pay in an
amount equal to 200% of the Employee's annual base salary at the time of such
termination, plus the full amount of Employee's annual bonus at the "on-target"
level for the fiscal year in which Employee is terminated, which amount shall be
paid in lieu of any bonus or commission that may be owing, or becomes owed to
Employee at any time thereafter.  Any severance payments to which the Employee
is entitled pursuant to this section shall be paid in a lump sum within thirty
(30) days of the Employee's termination.  In addition, for a period of up to
twelve (12) months after any termination under this Section 2(a)(i), the Company
shall reimburse the Employee for any COBRA premiums paid by the Employee for
continued group health insurance coverage (the "Employment Benefits").  Such
Employment Benefits shall terminate upon the earlier of (i) twelve months from
the date of the Employee's termination or (ii) upon commencement of new
employment by the Employee.

               (ii) Voluntary Resignation.  If the Employee's employment 
                    ---------------------                          
terminates by reason of the Employee's voluntary resignation (and is not an
Involuntary Termination or a termination for Cause), then the Employee shall not
be entitled to receive severance or other benefits following the date of such
termination, and the Company shall have no obligation to provide for the
continuation of any health and medical benefit or life insurance plans existing
on the date of such termination, except as otherwise required by applicable law.

               (iii) Disability; Death.  If the Company terminates the
                     -----------------                                
Employee's employment as a result of the Employee's Disability, or such
Employee's employment is terminated at any time due to the death of the
Employee, then the Employee shall not be entitled to receive severance or other
benefits following the date of such termination, and the Company shall have no
obligation to provide for the continuation of any health and medical benefit or
life insurance plans existing on the date of such termination, except as
otherwise required by applicable law.

               (iv) Termination for Cause.  If the Employee is terminated for 
                    ---------------------  
Cause, then the Employee shall not be entitled to receive any severance or other
benefits following the date of such termination, and the Company shall have no
obligation to provide for the continuation of any health and medical benefit or
life 

                                       2
<PAGE>
 
insurance plans existing on the date of such termination, except as otherwise
required by applicable law.

          (b)  Stock Option Acceleration in Connection with Change of Control.
               --------------------------------------------------------------  
In the event of any Change of Control, any exercisable or unvested portion of
any stock option granted to the Employee under the Company's stock option plans
(whether or not outstanding on the date of this Agreement) shall be
automatically become accelerated and immediately exercisable and vested in full
to the extent provided under this Section 2(b), and the Employee shall
automatically have the right to exercise all or any portion of such stock option
to the extent so accelerated, in addition to any portion of the option
exercisable prior to acceleration. Such acceleration upon a Change of Control
automatically shall occur ten (10) days prior to the consummation of such Change
of Control, but conditioned upon the consummation of the Change of Control and
the continued employment of the Employee to the date thereof.

               (i)  In the event of a Change of Control, the Employee shall be
automatically credited with an additional twenty-four (24) months of continuous
service for purposes of determining the exercisability and vesting of such
options if the consideration per share of the Company's Common Stock received
by the Company's stockholders as a result of the Change of Control is less than
$15.00 per share; or

               (ii) In the event of a Change of Control, the Employee shall 
automatically be credited with an additional thirty (30) months of continuous
service for purposes of determining the exercisability and vesting of such
options if the consideration per share of the Company's Common Stock received
by the Company's stockholders as a result of the Change of Control is at least 
$15.00 but less than $18.00; or

               (iii) In the event of a Change of Control, the Employee shall 
automatically be credited with an additional thirty-six (36) months of
continuous service for purposes of determining the exercisability and vesting of
such options, if the consideration per share of the Company's Common Stock
received by the Company's stockholders as a result of the Change of Control is
at least $18.00 per share.

          (c)  Release of Claims.  Employee's entitlement to any benefits
               -----------------                  
under this Section 2 is conditioned upon Employee's execution and delivery to
the Company of a general release of claims in a form satisfactory to the
Company.

          (d)  Limitation of Payments and Benefits.
               ----------------------------------- 

               (i)  To the extent that any of the payments and benefits provided
for in this Agreement or otherwise payable to the Employee constitute "parachute
payments" within the meaning of Section 280G of the Internal Revenue 

                                       3
<PAGE>
 
Code of 1986, as amended (the "Code"), and, but for this Section 2(d), would be
subject to the excise tax imposed by Section 4999 of the Code or any similar or
successor provision, the aggregate amount of such payments and benefits shall be
reduced, but only to the extent necessary so that none of such payments and
benefits are subject to excise tax pursuant to Section 4999 of the Code.

               (ii) Within sixty (60) days after the later of termination of
employment or the related Change of Control, the Company shall notify the
Employee in writing if it believes that any reduction in the payments and
benefits that would otherwise be paid or provided to the Employee under the
terms of this Agreement is required to comply with the provisions of Subsection
2(d)(i).  If the Company determines that any such reduction is required, it will
provide the Employee with copies of the information used and calculations made
by the Company to determine the amount of such reduction.  The Company shall
determine, in a fair and equitable manner after consultation with the Employee,
which payments and benefits are to be reduced so as to result in the maximum
benefit for the Employee.

               (iii) Within thirty (30) days after the Employee's receipt of
the Company's notice pursuant to Subsection 2(d)(ii), the Employee shall notify
the Company in writing if the Employee disagrees with the amount of reduction
determined by the Company, or the selection of the payments and the benefits to
be reduced.  As part of such notice, the Employee shall also advise the Company
of the amount of reduction, if any, that the Employee has, in good faith,
determined to be necessary to comply with the provisions of Subsection 2(d)(i)
and/or the payments and benefits to be reduced.  Failure by the Employee to
provide this notice within the time allowed will be treated by the Company as
acceptance by the Employee of the amount of reduction determined by the Company
and/or the payments and benefits to be reduced.  If any differences regarding
the amount of the reduction and/or the payments and benefits to be reduced have
not been resolved by mutual agreement within sixty (60) days after the
Employee's receipt of the Company's notice pursuant to Subsection 2(d)(ii), the
amount of reduction and/or the payments and benefits to be reduced as determined
by the Employee will be conclusive and binding on both parties unless, prior to
the expiration of such sixty (60) day period, the Company notifies the Employee
in writing of the Company's intention to have the matter submitted to
arbitration for resolution and proceeds to do so promptly.  If the Company gives
no notice to the Employee of a required reduction as provided in Subsection
2(d)(ii), the Employee may unilaterally determine the amount of reduction
required, if any, and/or the payments and benefits to be reduced, and, upon
written notice to the Company, the amount and/or the payments and benefits to be
reduced will be conclusive and binding on both parties.

               (iv) If, as a result of the reductions required by Subsection
2(d)(i), the amounts previously paid to the Employee exceed the amount to which
the Employee is entitled, the Employee will promptly return the excess amount to
the Company.

foregoing conditions shall be a voluntary resignation, and not an involuntary
termination, unless the Employee gives written notice of any such condition(s)
to the Board and allows the Company at least 10 days thereafter to correct such
condition(s).  It shall also be an Involuntary Termination if the Company
terminates the Employee for any reason other than Disability, death or for
Cause.

          (c)  Cause.  For purposes of this Agreement, a termination "for Cause"
               -----                                                            
occurs if the Employee is terminated for any of the following reasons:

physical violence toward employees, customers, consultants or suppliers of the
Company; or

               (vi)  The Employee's conviction (including any plea of guilty or
nolo contendre) for any criminal act that impairs his ability to perform his
duties for the Company.

          (d)  Disability.  "Disability" shall mean that the Employee is unable
               ----------

incapacity due to physical or mental illness for 120 days (not necessarily
consecutive) in any one 

                                       6
<PAGE>
 
year period. Termination resulting from Disability may only be effected after at
least 30 days' written notice by the Company of its intention to terminate the
Employee's employment. In the event that the Employee resumes the performance of
substantially all of his duties as an employee of the Company before the
termination of his employment becomes effective, the notice of intent to
terminate shall automatically be deemed to have been revoked.

     4.   Employee Covenant Regarding Nonsolicitation.  For a period of one (1)
          -------------------------------------------                          
year following termination of employment for any reason, the Employee shall not
recruit, solicit, or invite the solicitation of any employees of the Company to
terminate their employment with the Company.

     5.   Successors.
          ---------- 

          (a)  Company's Successors.  Any successor to the Company (whether
               --------------------                                        
direct or indirect and whether by purchase, lease, merger, consolidation,
liquidation or otherwise) to all or substantially all of the Company's business
and/or assets shall assume the obligations under this Agreement and agree
expressly to perform the obligations under this Agreement in the same manner and
to the same extent as the Company would be required to perform such obligations
in the absence of a succession.  For all purposes under this Agreement, the term
"Company" shall include any successor to the Company's business and/or assets
which executes and delivers the assumption agreement described in this
subsection (a) or which becomes bound by the terms of this Agreement by
operation of law.

          (b)  Employee's Successors.  All rights of the Employee hereunder

legal representatives, executors, administrators, successors, heirs,
distributees, devisees and legatees. Employee shall have no right to assign any
of his obligations or duties under this Agreement to any other person or entity.

this Agreement shall be in writing and shall be deemed to have been duly given
when personally delivered or when mailed by U.S. registered or certified mail,
return receipt requested and postage prepaid.  In the case of the Employee,
mailed notices shall be addressed to him at the home address which he most
recently communicated to the Company in writing.  In the case of the Company,
mailed notices shall be addressed to its corporate headquarters, and all notices
shall be directed to the attention of its Secretary.

          (b)  Notice of Termination.  Any termination by the Company for Cause
               ---------------------                                           
or by the Employee as a result of a voluntary resignation or an Involuntary
Termination shall be communicated by a notice of termination to the other party
hereto given in accordance with Section 6 of this Agreement.  Such notice shall

                                       7
<PAGE>
 
indicate the specific termination provision in this Agreement relied upon, shall
set forth in reasonable detail the facts and circumstances claimed to provide a
basis for termination under the provision so indicated, and shall specify the
termination date (which shall be not more than 15 days after the giving of such
notice).

     7.   Miscellaneous Provisions.

mitigate the amount of any payment contemplated by this Agreement (whether by
seeking new employment or in any other manner), nor shall any such payment be
reduced by any earnings that the Employee may receive from any other source.

          (b)  Waiver.  No provision of this Agreement shall be modified, waived
               ------                                                           
or discharged unless the modification, waiver or discharge is agreed to in
writing and signed by the Employee and by an authorized officer of the Company
(other than the Employee).  No waiver by either party of any breach of, or of
compliance with, any condition or provision of this Agreement by the other party
shall be considered a waiver of any other condition or provision or of the same
condition or provision at another time.

          (c)  Choice of Law.  The validity, interpretation, construction and
               -------------

and effect.

          (e)  Arbitration.  In the event of any dispute or claim relating to or
               -----------                                                      
arising out of the Employee's employment relationship with the Company, this
Agreement, or the termination of the Employee's employment with the Company for
any reason (including, but not limited to, any claims of breach of contract,
wrongful termination, fraud or age, race, sex, national origin, disability or
other discrimination or harassment), the Employee and the Company agree that all
such disputes shall be fully, finally and exclusively resolved by binding
arbitration conducted by the American Arbitration Association in Santa Clara
County, California.  The Employee and the Company hereby knowingly and willingly
waive their respective rights to have any such disputes or claims tried to a
judge or jury.  Provided, however, that this arbitration provision shall not
apply to any disputes or claims relating to or arising out of the actual or
alleged misuse or misappropriation of the Company's property, including, but not
limited to, its trade secrets or proprietary information.

          (f)  No Assignment of Benefits.  The rights of any person to payments
               -------------------------

                                CONSILIUM, INC.

                          CHANGE OF CONTROL AGREEMENT
                          ---------------------------

     This Change of Control Agreement (the "Agreement") is effective as of
December 11, 1996, by and between Jonathan J. Golovin (the "Employee"), and
Consilium, Inc., a Delaware corporation (the "Company").


                                    RECITALS

     A.   The Employee presently serves at the pleasure of the Board of
Directors as Chairman of the Board and Chief Technical Officer of the Company
and performs significant strategic and management responsibilities necessary to
the continued conduct of the Company's business and operations.

     B.   The Board of Directors of the Company (the "Board") has determined
that it is in the best interests of the Company and its stockholders to assure
that the Company will have the continued dedication and objectivity of the
Employee, notwithstanding the possibility or occurrence of a Change of Control
(as defined below) of the Company.

     C.   The Board believes that it is imperative to provide the Employee with
certain severance benefits upon the Employee's termination of employment
following a Change of Control which provide the Employee with enhanced financial
security and provide sufficient incentive and encouragement to the Employee to
remain with the Company following a Change of Control.

     D.   Certain capitalized terms used in the Agreement are defined in Section
3 below.

     In consideration of the mutual covenants herein contained, and in
consideration of the continuing employment of Employee by the Company, the
parties agree as follows:

     1.   Term of Employment.  The Company and the Employee agree that the
          ------------------                                              
Employee's employment is at will, and that their employment relationship may be
terminated by either party at any time, with or without cause.  If the
Employee's employment terminates for any reason, the Employee shall not be
entitled to any payments, benefits, damages, awards or compensation other than
as provided by this Agreement.  The provisions of this Agreement shall terminate
on December 31, 2001, (except that the Employee's employment by the Company
shall continue to be "at will"), unless a Change of Control occurs on or prior
to that date, in which case the provisions of this Agreement shall terminate
upon the earlier to occur of (i) the date that all obligations of the parties
hereunder have been satisfied, or (ii) twelve (12) 

                                       1
<PAGE>
 
months after the Change of Control. Any termination of this Agreement shall not
affect any required payment or benefit that accrues prior to such termination.

     2.   Severance Benefits.  Subject to Sections 2(d) and 2(e) below,
          ------------------                                           

          (a)  Termination Following A Change of Control.  If the Employee's
               -----------------------------------------                    
employment is terminated within twelve (12) months following a Change of
Control, then the Employee shall be entitled to receive severance benefits as
follows:

               (i)  Involuntary Termination.  If the Employee's employment is
                    -----------------------                                  
terminated as a result of Involuntary Termination (as defined in Section 3(b)
below), then the Employee shall be entitled to receive severance pay in an
amount equal to 200% of the Employee's annual base salary at the time of such
termination, plus the full amount of Employee's annual bonus at the "on-target"
level for the fiscal year in which Employee is terminated, which amount shall be
paid in lieu of any bonus or commission that may be owing, or becomes owed to
Employee at any time thereafter.  Any severance payments to which the Employee
is entitled pursuant to this section shall be paid in a lump sum within thirty
(30) days of the Employee's termination.  In addition, for a period of up to
twelve (12) months after any termination under this Section 2(a)(i), the Company
shall reimburse the Employee for any COBRA premiums paid by the Employee for
continued group health insurance coverage (the "Employment Benefits").  Such
Employment Benefits shall terminate upon the earlier of (i) twelve months from
the date of the Employee's termination or (ii) upon commencement of new
employment by the Employee.

               (ii) Voluntary Resignation.  If the Employee's employment 
                    ---------------------                          
terminates by reason of the Employee's voluntary resignation (and is not an
Involuntary Termination or a termination for Cause), then the Employee shall not
be entitled to receive severance or other benefits following the date of such
termination, and the Company shall have no obligation to provide for the
continuation of any health and medical benefit or life insurance plans existing
on the date of such termination, except as otherwise required by applicable law.

               (iii) Disability; Death.  If the Company terminates the
                     -----------------                                
Employee's employment as a result of the Employee's Disability, or such
Employee's employment is terminated at any time due to the death of the
Employee, then the Employee shall not be entitled to receive severance or other
benefits following the date of such termination, and the Company shall have no
obligation to provide for the continuation of any health and medical benefit or
life insurance plans existing on the date of such termination, except as
otherwise required by applicable law.

               (iv) Termination for Cause.  If the Employee is terminated for 
                    ---------------------  
Cause, then the Employee shall not be entitled to receive any severance or other
benefits following the date of such termination, and the Company shall have no
obligation to provide for the continuation of any health and medical benefit or
life 

                                       2
<PAGE>
 
insurance plans existing on the date of such termination, except as otherwise
required by applicable law.

          (b)  Stock Option Acceleration in Connection with Change of Control.
               --------------------------------------------------------------  
In the event of any Change of Control, any exercisable or unvested portion of
any stock option granted to the Employee under the Company's stock option plans
(whether or not outstanding on the date of this Agreement) shall be
automatically become accelerated and immediately exercisable and vested in full
to the extent provided under this Section 2(b), and the Employee shall
automatically have the right to exercise all or any portion of such stock option
to the extent so accelerated, in addition to any portion of the option
exercisable prior to acceleration. Such acceleration upon a Change of Control
automatically shall occur ten (10) days prior to the consummation of such Change
of Control, but conditioned upon the consummation of the Change of Control and
the continued employment of the Employee to the date thereof. In the event of a 
Change of Control, the Employee shall be automatically credited with an 
additional twenty-four (24) months of continuous service for purposes of 
determining the exercisability and vesting of such options.

          (c)  Release of Claims.  Employee's entitlement to any benefits
               -----------------                  
under this Section 2 is conditioned upon Employee's execution and delivery to
the Company of a general release of claims in a form satisfactory to the
Company.

          (d)  Limitation of Payments and Benefits.
               ----------------------------------- 

               (i)  To the extent that any of the payments and benefits provided
for in this Agreement or otherwise payable to the Employee constitute "parachute
payments" within the meaning of Section 280G of the Internal Revenue Code of
1986, as amended (the "Code"), and, but for this Section 2(d), would be subject
to the excise tax imposed by Section 4999 of the Code or any similar or
successor provision, the aggregate amount of such payments and benefits shall be
reduced, but only to the extent necessary so that none of such payments and
benefits are subject to excise tax pursuant to Section 4999 of the Code.

               (ii) Within sixty (60) days after the later of termination of
employment or the related Change of Control, the Company shall notify the
Employee in writing if it believes that any reduction in the payments and
benefits that would otherwise be paid or provided to the Employee under the
terms of this Agreement is required to comply with the provisions of Subsection
2(d)(i).  If the Company determines that any such reduction is required, it will
provide the Employee with copies of the information used and calculations made
by the Company to determine the amount of such reduction.  The Company shall
determine, in a fair and equitable manner after consultation with the Employee,
which payments and benefits are to be reduced so as to result in the maximum
benefit for the Employee.

                                       3
<PAGE>
 
               (iii) Within thirty (30) days after the Employee's receipt of
the Company's notice pursuant to Subsection 2(d)(ii), the Employee shall notify
the Company in writing if the Employee disagrees with the amount of reduction
determined by the Company, or the selection of the payments and the benefits to
be reduced.  As part of such notice, the Employee shall also advise the Company
of the amount of reduction, if any, that the Employee has, in good faith,
determined to be necessary to comply with the provisions of Subsection 2(d)(i)
and/or the payments and benefits to be reduced.  Failure by the Employee to
provide this notice within the time allowed will be treated by the Company as
acceptance by the Employee of the amount of reduction determined by the Company
and/or the payments and benefits to be reduced.  If any differences regarding
the amount of the reduction and/or the payments and benefits to be reduced have
not been resolved by mutual agreement within sixty (60) days after the
Employee's receipt of the Company's notice pursuant to Subsection 2(d)(ii), the
amount of reduction and/or the payments and benefits to be reduced as determined
by the Employee will be conclusive and binding on both parties unless, prior to
the expiration of such sixty (60) day period, the Company notifies the Employee
in writing of the Company's intention to have the matter submitted to
arbitration for resolution and proceeds to do so promptly.  If the Company gives
no notice to the Employee of a required reduction as provided in Subsection
2(d)(ii), the Employee may unilaterally determine the amount of reduction
required, if any, and/or the payments and benefits to be reduced, and, upon
written notice to the Company, the amount and/or the payments and benefits to be
reduced will be conclusive and binding on both parties.

               (iv) If, as a result of the reductions required by Subsection
2(d)(i), the amounts previously paid to the Employee exceed the amount to which
the Employee is entitled, the Employee will promptly return the excess amount to
the Company.

     3.   Definition of Terms.  The following terms referred to in this
          -------------------

representing fifty percent (50%) or more of the total voting power represented
by the Company's then outstanding voting securities; or

               (ii)  A merger or consolidation of the Company with any other
corporation, other than a merger or consolidation which would result in the

surviving entity, or a parent entity thereof outstanding immediately after such
merger or consolidation; or

               (iii) The complete liquidation of the Company; or

               (i)   Without the Employee's express written consent, the
assignment to the Employee of any significant duties or the significant
reduction of the Employee's duties, either of which is materially inconsistent

for Cause;

               (ii)  Without the Employee's express written consent, a

               (iii) A material reduction by the Company in the base salary

               (v)   The relocation of the Employee to a facility or a location

foregoing conditions shall be a voluntary resignation, and not an involuntary
termination, unless the Employee gives written notice of any such condition(s)
to the Board and allows the Company at least 10 days thereafter to correct such

                                       5
<PAGE>
 
condition(s).  It shall also be an Involuntary Termination if the Company
terminates the Employee for any reason other than Disability, death or for
Cause.

          (c)  Cause.  For purposes of this Agreement, a termination "for Cause"
               -----                                                            
occurs if the Employee is terminated for any of the following reasons:

employment or Company records;

               (ii)  Improper disclosure of the Company's confidential or

including but not limited to sexual harassment, threats of harm or acts of
physical violence toward employees, customers, consultants or suppliers of the
Company; or

               (vi)  The Employee's conviction (including any plea of guilty or
nolo contendre) for any criminal act that impairs his ability to perform his
duties for the Company.

          (d)  Disability.  "Disability" shall mean that the Employee is unable
               ----------                                                      
to perform his duties as an employee of the Company as the result of his
incapacity due to physical or mental illness for 120 days (not necessarily
consecutive) in any one year period.  Termination resulting from Disability may
only be effected after at least 30 days' written notice by the Company of its
intention to terminate the Employee's employment.  In the event that the
Employee resumes the performance of substantially all of his duties as an
employee of the Company before the termination of his employment becomes
effective, the notice of intent to terminate shall automatically be deemed to
have been revoked.

     4.   Employee Covenant Regarding Nonsolicitation.  For a period of one (1)
          -------------------------------------------

recruit, solicit, or invite the solicitation of any employees of the Company to
terminate their employment with the Company.

     5.   Successors.

               --------------------                                        
direct or indirect and whether by purchase, lease, merger, consolidation,
liquidation 

                                       6

or otherwise) to all or substantially all of the Company's business and/or
assets shall assume the obligations under this Agreement and agree expressly to
perform the obligations under this Agreement in the same manner and to the same
extent as the Company would be required to perform such obligations in the
absence of a succession. For all purposes under this Agreement, the term
"Company" shall include any successor to the Company's business and/or assets
which executes and delivers the assumption agreement described in this
subsection (a) or which becomes bound by the terms of this Agreement by
operation of law.

when personally delivered or when mailed by U.S. registered or certified mail,
return receipt requested and postage prepaid.  In the case of the Employee,
mailed notices shall be addressed to him at the home address which he most
recently communicated to the Company in writing.  In the case of the Company,
mailed notices shall be addressed to its corporate headquarters, and all notices
shall be directed to the attention of its Secretary.

          (b)  Notice of Termination.  Any termination by the Company for Cause
               ---------------------

Termination shall be communicated by a notice of termination to the other party
hereto given in accordance with Section 6 of this Agreement.  Such notice shall

reduced by any earnings that the Employee may receive from any other source.

          (b)  Waiver.  No provision of this Agreement shall be modified, waived
               ------

writing and signed by the Employee and by an authorized officer of the Company

                                       7
<PAGE>

Agreement, or the termination of the Employee's employment with the Company for
any reason (including, but not limited to, any claims of breach of contract,
wrongful termination, fraud or age, race, sex, national origin, disability or
other discrimination or harassment), the Employee and the Company agree that all
such disputes shall be fully, finally and exclusively resolved by binding

                                CONSILIUM, INC.

                          CHANGE OF CONTROL AGREEMENT
                          ---------------------------

     This Change of Control Agreement (the "Agreement") is effective as of
________________________, 199[__], by and between ______________________ (the
"Employee"), and Consilium, Inc., a Delaware corporation (the "Company").


                                    RECITALS

     A.   The Employee presently serves at the pleasure of the Board of
Directors as ____________________________ of the Company and performs
significant strategic and management responsibilities necessary to the continued
conduct of the Company's business and operations.

     B.   The Board of Directors of the Company (the "Board") has determined
that it is in the best interests of the Company and its stockholders to assure
that the Company will have the continued dedication and objectivity of the
Employee, notwithstanding the possibility or occurrence of a Change of Control
(as defined below) of the Company.

     C.   The Board believes that it is imperative to provide the Employee with
certain severance benefits upon the Employee's termination of employment
following a Change of Control which provide the Employee with enhanced financial
security and provide sufficient incentive and encouragement to the Employee to
remain with the Company following a Change of Control.

     D.   Certain capitalized terms used in the Agreement are defined in Section
3 below.

     In consideration of the mutual covenants herein contained, and in
consideration of the continuing employment of Employee by the Company, the
parties agree as follows:

     1.   Term of Employment.  The Company and the Employee agree that the
          ------------------                                              
Employee's employment is at will, and that their employment relationship may be
terminated by either party at any time, with or without cause.  If the
Employee's employment terminates for any reason, the Employee shall not be
entitled to any payments, benefits, damages, awards or compensation other than
as provided by this Agreement.  The provisions of this Agreement shall terminate
on December 31, 2001, (except that the Employee's employment by the Company
shall continue to be "at will"), unless a Change of Control occurs on or prior
to that date, in which case the provisions of this Agreement shall terminate
upon the earlier to occur of (i) the date that all obligations of the parties
hereunder have been satisfied, or (ii) twelve (12) 

                                       1

months after the Change of Control. Any termination of this Agreement shall not
affect any required payment or benefit that accrues prior to such termination.

     2.   Severance Benefits.  Subject to Sections 2(d) and 2(e) below,
          ------------------                                           

          (a)  Termination Following A Change of Control.  If the Employee's
               -----------------------------------------                    
employment is terminated within twelve (12) months following a Change of
Control, then the Employee shall be entitled to receive severance benefits as
follows:

               (i)  Involuntary Termination.  If the Employee's employment is
                    -----------------------                                  
terminated as a result of Involuntary Termination (as defined in Section 3(b)
below), then the Employee shall be entitled to receive severance pay in an
amount equal to 100% of the Employee's annual base salary at the time of such
termination, plus the full amount of Employee's annual bonus at the "on-target"
level for the fiscal year in which Employee is terminated, which amount shall be
paid in lieu of any bonus or commission that may be owing, or becomes owed to
Employee at any time thereafter.  Any severance payments to which the Employee
is entitled pursuant to this section shall be paid in a lump sum within thirty
(30) days of the Employee's termination.  In addition, for a period of up to
twelve (12) months after any termination under this Section 2(a)(i), the Company
shall reimburse the Employee for any COBRA premiums paid by the Employee for
continued group health insurance coverage (the "Employment Benefits").  Such
Employment Benefits shall terminate upon the earlier of (i) twelve months from
the date of the Employee's termination or (ii) upon commencement of new
employment by the Employee.

               (ii) Voluntary Resignation.  If the Employee's employment 
                    ---------------------                          
terminates by reason of the Employee's voluntary resignation (and is not an
Involuntary Termination or a termination for Cause), then the Employee shall not
be entitled to receive severance or other benefits following the date of such
termination, and the Company shall have no obligation to provide for the
continuation of any health and medical benefit or life insurance plans existing
on the date of such termination, except as otherwise required by applicable law.

               (iii) Disability; Death.  If the Company terminates the
                     -----------------                                
Employee's employment as a result of the Employee's Disability, or such
Employee's employment is terminated at any time due to the death of the
Employee, then the Employee shall not be entitled to receive severance or other
benefits following the date of such termination, and the Company shall have no
obligation to provide for the continuation of any health and medical benefit or
life insurance plans existing on the date of such termination, except as
otherwise required by applicable law.

               (iv) Termination for Cause.  If the Employee is terminated for 
                    ---------------------  
Cause, then the Employee shall not be entitled to receive any severance or other
benefits following the date of such termination, and the Company shall have no
obligation to provide for the continuation of any health and medical benefit or
life 

                                       2

insurance plans existing on the date of such termination, except as otherwise
required by applicable law.

          (b)  Stock Option Acceleration in Connection with Change of Control.
               --------------------------------------------------------------  
In the event of any Change of Control, any exercisable or unvested portion of
any stock option granted to the Employee under the Company's stock option plans
(whether or not outstanding on the date of this Agreement) shall be
automatically become accelerated and immediately exercisable and vested in full
to the extent provided under this Section 2(b), and the Employee shall
automatically have the right to exercise all or any portion of such stock option
to the extent so accelerated, in addition to any portion of the option
exercisable prior to acceleration. Such acceleration upon a Change of Control
automatically shall occur ten (10) days prior to the consummation of such Change
of Control, but conditioned upon the consummation of the Change of Control and
the continued employment of the Employee to the date thereof.

               (i)  Subject to subparagraph (ii) below of this Section 2(b), in
the event of a Change of Control, the Employee shall be automatically credited
with an additional twelve (12) months of continuous service for purposes of
determining the exercisability and vesting of such options.

               (ii) If prior to the occurrence of a Change of Control, the Board
shall request in writing that the Employee continue as an employee of (or
consultant to) the Company or its successor immediately following the Change of
Control, then (A) upon the occurrence of the Change of Control, the Employee
shall be automatically credited with an additional twelve (12) months of
continuous service for purposes of determining the exercisability and vesting of
such options, (B) the vesting of unvested shares (or the right to receive
equivalent cash value, as appropriate) shall continue during the period of
continued employment, and (C) the Employee shall be automatically credited with
an additional twelve (12) months of continuous service for purposes of
determining the exercisability and vesting of such options (including any right
to receive cash into which such option has been converted) upon the earlier of
(1) the date of termination of the Employee's employment (or association as a
consultant) if at any time during the 90-day period following the Change of
Control such employment or association is terminated as a result of Involuntary
Termination, death or Disability (but not if termination results from the
Employee's voluntary resignation (other than an Involuntary Termination) or if
the termination is for Cause, or (2) the date 90 days following the Change of
Control if on such date the Employee remains an employee (or consultant) of the
Company or its successor.

          (c)  Release of Claims.  Employee's entitlement to any benefits
               -----------------                  
under this Section 2 is conditioned upon Employee's execution and delivery to
the Company of a general release of claims in a form satisfactory to the
Company.

                                       3
<PAGE>
 
          (d)  Limitation of Payments and Benefits.
               ----------------------------------- 

               (i)  To the extent that any of the payments and benefits provided
for in this Agreement or otherwise payable to the Employee constitute "parachute
payments" within the meaning of Section 280G of the Internal Revenue Code of
1986, as amended (the "Code"), and, but for this Section 2(d), would be subject
to the excise tax imposed by Section 4999 of the Code or any similar or
successor provision, the aggregate amount of such payments and benefits shall be
reduced, but only to the extent necessary so that none of such payments and
benefits are subject to excise tax pursuant to Section 4999 of the Code.

               (ii) Within sixty (60) days after the later of termination of
employment or the related Change of Control, the Company shall notify the
Employee in writing if it believes that any reduction in the payments and
benefits that would otherwise be paid or provided to the Employee under the
terms of this Agreement is required to comply with the provisions of Subsection
2(d)(i).  If the Company determines that any such reduction is required, it will
provide the Employee with copies of the information used and calculations made
by the Company to determine the amount of such reduction.  The Company shall
determine, in a fair and equitable manner after consultation with the Employee,
which payments and benefits are to be reduced so as to result in the maximum
benefit for the Employee.

               (iii) Within thirty (30) days after the Employee's receipt of
the Company's notice pursuant to Subsection 2(d)(ii), the Employee shall notify
the Company in writing if the Employee disagrees with the amount of reduction
determined by the Company, or the selection of the payments and the benefits to
be reduced.  As part of such notice, the Employee shall also advise the Company
of the amount of reduction, if any, that the Employee has, in good faith,
determined to be necessary to comply with the provisions of Subsection 2(d)(i)
and/or the payments and benefits to be reduced.  Failure by the Employee to
provide this notice within the time allowed will be treated by the Company as
acceptance by the Employee of the amount of reduction determined by the Company
and/or the payments and benefits to be reduced.  If any differences regarding
the amount of the reduction and/or the payments and benefits to be reduced have
not been resolved by mutual agreement within sixty (60) days after the
Employee's receipt of the Company's notice pursuant to Subsection 2(d)(ii), the
amount of reduction and/or the payments and benefits to be reduced as determined
by the Employee will be conclusive and binding on both parties unless, prior to
the expiration of such sixty (60) day period, the Company notifies the Employee
in writing of the Company's intention to have the matter submitted to
arbitration for resolution and proceeds to do so promptly.  If the Company gives
no notice to the Employee of a required reduction as provided in Subsection
2(d)(ii), the Employee may unilaterally determine the amount of reduction
required, if any, and/or the payments and benefits to be reduced, and, upon
written notice to the Company, the amount and/or the payments and benefits to be
reduced will be conclusive and binding on both parties.

                                       4
<PAGE>
 
               (iv) If, as a result of the reductions required by Subsection
2(d)(i), the amounts previously paid to the Employee exceed the amount to which
the Employee is entitled, the Employee will promptly return the excess amount to
the Company.

foregoing conditions shall be a voluntary resignation, and not an involuntary
termination, unless the Employee gives written notice of any such condition(s)
to the Board and allows the Company at least 10 days thereafter to correct such
condition(s).  It shall also be an Involuntary Termination if the Company
terminates the Employee for any reason other than Disability, death or for
Cause.

               -----

incapacity due to physical or mental illness for 120 days (not necessarily
consecutive) in any one year period.  Termination resulting from Disability may
only be effected after at least 30 days' written notice by the Company of its
intention to terminate the Employee's employment.  In the event that the
Employee resumes the performance of substantially all of his duties as an

effective, the notice of intent to terminate shall automatically be deemed to
have been revoked.

     4.   Employee Covenant Regarding Nonsolicitation.  For a period of one (1)
          -------------------------------------------

liquidation or otherwise) to all or substantially all of the Company's business
and/or assets shall assume the obligations under this Agreement and agree
expressly to perform the obligations under this Agreement in the same manner and
to the same extent as the Company would be required to perform such obligations

Company is a "publicly held corporation" within the meaning of Section 162(m),
the Board may establish a Committee of "outside directors" within the meaning of

anticipated to result in the payment of employee remuneration that would
otherwise exceed the limit on employee remuneration deductible for income tax
purposes pursuant to Section 162(m).

      4.  SHARES SUBJECT TO PLAN.
          ---------------------- 

          4.1  MAXIMUM NUMBER OF SHARES ISSUABLE. Subject to adjustment as
provided in Section 4.2, the maximum aggregate number of shares of Stock that
may be issued under the Plan shall be the sum of (a) Three Hundred Ninety
Thousand (390,000) shares, (b) the number of shares of Stock, as of the
Effective Date, subject to outstanding options granted pursuant to the Company's
Fourth Amended and Restated 1983 Stock Option Plan and 1993 Stock Option Plan
(collectively, the "PRIOR PLANS"), which amount is One Million Six Hundred
Seventy-Seven Thousand Six Hundred Fifty-Four (1,677,654) shares (the "PRIOR
PLAN OPTIONS"), and (c) the number of shares of Stock available for future grant
under the Prior Plans as of the Effective Date, which amount is Two Hundred
Forty-Five Thousand Six Hundred Twenty-Four (245,624) (the "PRIOR PLAN AVAILABLE
SHARES"), resulting in an aggregate total of Two Million Three Hundred Thirteen
Thousand Two Hundred Seventy-Eight (2,313,278) shares (the "SHARE RESERVE") and
shall consist of authorized but unissued or reacquired shares of Stock or any
combination thereof. Notwithstanding the foregoing, the Share Reserve,
determined at any time, shall be reduced by (a) the number of shares remaining
subject to outstanding Prior

                                       5
<PAGE>
 
Plan Options, (b) the number of shares issued upon the exercise of Prior Plan
Options, and (c) the number of shares, if any, of the Prior Plan Available
Shares which are issued upon the exercise of options granted under the Prior
Plans subsequent to the Effective Date. If an outstanding Option for any reason
expires or is terminated or canceled, or if shares of Stock acquired, subject to
repurchase, upon the exercise of an Option are repurchased by the Company, the
shares of Stock allocable to the unexercised portion of such Option or such
repurchased shares of Stock shall again be available for issuance under the
Plan.

          4.2  ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of any
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification or similar change in the capital structure of the Company,
appropriate adjustments shall be made in the number and class of shares subject
to the Plan and to any outstanding Options, in the Section 162(m) Grant Limit
set forth in Section 5.4, and in the exercise price per share of any outstanding
Options. If a majority of the shares which are of the same class as the shares
that are subject to outstanding Options are exchanged for, converted into, or
otherwise become (whether or not pursuant to an Ownership Change Event, as
defined in Section 8.1) shares of another corporation (the "NEW SHARES"), the
Board may unilaterally amend the outstanding Options to provide that such
Options are exercisable for New Shares. In the event of any such amendment, the
number of shares subject to, and the exercise price per share of, the
outstanding Options shall be adjusted in a fair and equitable manner as
determined by the Board, in its sole discretion. Notwithstanding the foregoing,
any fractional share resulting from an adjustment pursuant to this Section 4.2
shall be rounded up or down to the nearest whole number, as determined by the
Board, and in no event may the exercise price of any Option be decreased to an
amount less than the par value, if any, of the stock subject to the Option. The
adjustments determined by the Board pursuant to this Section 4.2 shall be final,
binding and conclusive.

     5.   ELIGIBILITY AND OPTION LIMITATIONS.
          ---------------------------------- 

          5.1  PERSONS ELIGIBLE FOR OPTIONS.  Options may be granted only to
Employees, Consultants, and Directors.  For purposes of the foregoing sentence,
"Employees," "Consultants" and "Directors" shall include prospective Employees,
prospective Consultants and prospective Directors to whom Options are granted in
connection with written offers of employment or other service relationship with
the Participating Company Group.  Eligible persons may be granted more than one
(1) Option.

          5.2  OPTION GRANT RESTRICTIONS. Any person who is not an Employee on
the effective date of the grant of an Option to such person may be granted only
a Nonstatutory Stock Option. An Incentive Stock Option granted to a prospective
Employee upon the condition that such person become an Employee shall be deemed
granted effective on the date such person commences service with a Participating
Company, with an exercise price determined as of such date in accordance with
Section 6.1.

          5.3  FAIR MARKET VALUE LIMITATION. To the extent that options
designated as Incentive Stock Options (granted under all stock option plans of
the Participating Company Group, including the Plan) become exercisable by an
Optionee for the first time during any

                                       6
<PAGE>
 
calendar year for stock having an aggregate Fair Market Value greater than One
Hundred Thousand Dollars ($100,000), the portion of such options which exceeds
such amount shall be treated as Nonstatutory Stock Options. For purposes of this
Section 5.3, options designated as Incentive Stock Options shall be taken into
account in the order in which they were granted, and the Fair Market Value of
stock shall be determined as of the time the option with respect to such stock
is granted. If the Code is amended to provide for a different limitation from
that set forth in this Section 5.3, such different limitation shall be deemed
incorporated herein effective as of the date and with respect to such Options as
required or permitted by such amendment to the Code. If an Option is treated as
an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by
reason of the limitation set forth in this Section 5.3, the Optionee may
designate which portion of such Option the Optionee is exercising. In the
absence of such designation, the Optionee shall be deemed to have exercised the
Incentive Stock Option portion of the Option first. Separate certificates
representing each such portion shall be issued upon the exercise of the Option.

          5.4  SECTION 162(m) GRANT LIMIT.  Subject to adjustment as provided in
Section 4.2, at any such time as a Participating Company is a "publicly held
corporation" within the meaning of Section 162(m), no Employee shall be granted
one or more Options within any fiscal year of the Company which in the aggregate
are for the purchase of more than Two Hundred Thousand (200,000) shares;
provided, however, that the Company may make grant any newly-hired Employee an
Option for the purchase of up to Three Hundred Thousand (300,000) shares (the
"SECTION 162(M) GRANT LIMIT").  An Option which is canceled in the same fiscal
year of the Company in which it was granted shall continue to be counted against
the Section 162(m) Grant Limit for such period.

     6.   TERMS AND CONDITIONS OF OPTIONS.  Options shall be evidenced by Option
          -------------------------------                                       
Agreements specifying the number of shares of Stock covered thereby, in such
form as the Board shall from time to time establish.  Option Agreements may
incorporate all or any of the terms of the Plan by reference and shall comply
with and be subject to the following terms and conditions:

          6.1  EXERCISE PRICE.  The exercise price for each Option shall be
established in the sole discretion of the Board; provided, however, that (a) the
exercise price per share for an Option shall be not less than the Fair Market
Value of a share of Stock on the effective date of grant of the Option and (b)
no Incentive Stock Option granted to a Ten Percent Owner Optionee shall have an
exercise price per share less than one hundred ten percent (110%) of the Fair
Market Value of a share of Stock on the effective date of grant of the Option.
Notwithstanding the foregoing, an Option (whether an Incentive Stock Option or a
Nonstatutory Stock Option) may be granted with an exercise price lower than the
minimum exercise price set forth above if such Option is granted pursuant to an
assumption or substitution for another option in a manner qualifying under the
provisions of Section 424(a) of the Code.

          6.2  EXERCISE PERIOD. Options shall be exercisable at such time or
times, or upon such event or events, and subject to such terms, conditions,
performance criteria, and restrictions as shall be determined by the Board and
set forth in the Option Agreement

                                       7
<PAGE>
 
evidencing such Option; provided, however, that (a) no Incentive Stock Option
shall be exercisable after the expiration of ten (10) years after the effective
date of grant of such Option, (b) no Incentive Stock Option granted to a Ten
Percent Owner Optionee shall be exercisable after the expiration of five (5)
years after the effective date of grant of such Option, and (c) no Option
granted to a prospective Employee, prospective Consultant or prospective
Director may become exercisable prior to the date on which such person commences
service with a Participating Company.

          6.3  PAYMENT OF EXERCISE PRICE.

               (a)  FORMS OF CONSIDERATION AUTHORIZED. Except as otherwise
provided below, payment of the exercise price for the number of shares of Stock
being purchased pursuant to any Option shall be made (i) in cash, by check, or
cash equivalent, (ii) by tender to the Company of shares of Stock owned by the
Optionee having a Fair Market Value (as determined by the Company without regard
to any restrictions on transferability applicable to such stock by reason of
federal or state securities laws or agreements with an underwriter for the
Company) not less than the exercise price, (iii) by the assignment of the
proceeds of a sale or loan with respect to some or all of the shares being
acquired upon the exercise of the Option (including, without limitation, through
an exercise complying with the provisions of Regulation T as promulgated from
time to time by the Board of Governors of the Federal Reserve System) (a
"CASHLESS EXERCISE"), (iv) by the Optionee's promissory note in a form approved
by the Company, (v) by such other consideration as may be approved by the Board
from time to time to the extent permitted by applicable law, or (vi) by any
combination thereof. The Board may at any time or from time to time, by adoption
of or by amendment to the standard forms of Option Agreement described in
Section 7, or by other means, grant Options which do not permit all of the
foregoing forms of consideration to be used in payment of the exercise price or
which otherwise restrict one or more forms of consideration.

               (b)  TENDER OF STOCK. Notwithstanding the foregoing, an Option
may not be exercised by tender to the Company of shares of Stock to the extent
such tender of Stock would constitute a violation of the provisions of any law,
regulation or agreement restricting the redemption of the Company's stock.
Unless otherwise provided by the Board, an Option may not be exercised by tender
to the Company of shares of Stock unless such shares either have been owned by
the Optionee for more than six (6) months or were not acquired, directly or
indirectly, from the Company.

               (c)  CASHLESS EXERCISE. The Company reserves, at any and all
times, the right, in the Company's sole and absolute discretion, to establish,
decline to approve or terminate any program or procedures for the exercise of
Options by means of a Cashless Exercise.

               (d)  PAYMENT BY PROMISSORY NOTE. No promissory note shall be
permitted if the exercise of an Option using a promissory note would be a
violation of any law. Any permitted promissory note shall be on such terms as
the Board shall determine at the time the Option is granted. The Board shall
have the authority to permit or require the Optionee to

                                       8
<PAGE>
 
secure any promissory note used to exercise an Option with the shares of Stock
acquired upon the exercise of the Option or with other collateral acceptable to
the Company. Unless otherwise provided by the Board, if the Company at any time
is subject to the regulations promulgated by the Board of Governors of the
Federal Reserve System or any other governmental entity affecting the extension
of credit in connection with the Company's securities, any promissory note shall
comply with such applicable regulations, and the Optionee shall pay the unpaid
principal and accrued interest, if any, to the extent necessary to comply with
such applicable regulations.

          6.4  TAX WITHHOLDING.  The Company shall have the right, but not the
obligation, to deduct from the shares of Stock issuable upon the exercise of an
Option, or to accept from the Optionee the tender of, a number of whole shares
of Stock having a Fair Market Value, as determined by the Company, equal to all
or any part of the federal, state, local and foreign taxes, if any, required by
law to be withheld by the Participating Company Group with respect to such
Option or the shares acquired upon the exercise thereof.  Alternatively or in
addition, in its sole discretion, the Company shall have the right to require
the Optionee, through payroll withholding, cash payment or otherwise, including
by means of a Cashless Exercise, to make adequate provision for any such tax
withholding obligations of the Participating Company Group arising in connection
with the Option or the shares acquired upon the exercise thereof.  The Company
shall have no obligation to deliver shares of Stock or to release shares of
Stock from an escrow established pursuant to the Option Agreement until the
Participating Company Group's tax withholding obligations have been satisfied by
the Optionee.

     7.   STANDARD FORMS OF OPTION AGREEMENT.
          ---------------------------------- 

          7.1  INCENTIVE STOCK OPTIONS. Unless otherwise provided by the Board
at the time the Option is granted, an Option designated as an "Incentive Stock
Option" shall comply with and be subject to the terms and conditions set forth
in the appropriate form of Incentive Stock Option Agreement adopted by the Board
concurrently with its adoption of the Plan and as amended from time to time.

          7.2  NONSTATUTORY STOCK OPTIONS. Unless otherwise provided by the
Board at the time the Option is granted, an Option designated as a "Nonstatutory
Stock Option" shall comply with and be subject to the terms and conditions set
forth in the appropriate form of Nonstatutory Stock Option Agreement adopted by
the Board concurrently with its adoption of the Plan and as amended from time to
time.

          7.3  STANDARD TERM OF OPTIONS. Except as otherwise provided in Section
6.2 or by the Board in the grant of an Option, any Option granted hereunder
shall have a term of ten (10) years from the effective date of grant of the
Option.

          7.4  AUTHORITY TO VARY TERMS. The Board shall have the authority from
time to time to vary the terms of any of the standard forms of Option Agreement
described in this Section 7 either in connection with the grant or amendment of
an individual Option or in connection with the authorization of a new standard
form or forms; provided, however, that the

                                       9
<PAGE>
 
terms and conditions of any such new, revised or amended standard form or forms
of Option Agreement are not inconsistent with the terms of the Plan. Such
authority shall include, but not by way of limitation, the authority to grant
Options which are immediately exercisable subject to the Company's right to
repurchase any unvested shares of Stock acquired by an Optionee upon the
exercise of an Option in the event such Optionee's employment or service with
the Participating Company Group is terminated for any reason, with or without
cause.

     8.   TRANSFER OF CONTROL.
          ------------------- 

          8.1  DEFINITIONS.

               (a)  An "OWNERSHIP CHANGE EVENT" shall be deemed to have occurred
if any of the following occurs with respect to the Company:

                    (i)   the direct or indirect sale or exchange in a single or
series of related transactions by the stockholders of the Company of more than
fifty percent (50%) of the voting stock of the Company;

                    (ii)  a merger or consolidation in which the Company is a
party;

                    (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or

                    (iv)  a liquidation or dissolution of the Company.

               (b)  A "TRANSFER OF CONTROL" shall mean an Ownership Change Event
or a series of related Ownership Change Events (collectively, the "TRANSACTION")
wherein the stockholders of the Company immediately before the Transaction do
not retain immediately after the Transaction, in substantially the same
proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "TRANSFEREE
CORPORATION(S)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

                                       10
<PAGE>
 
          8.2  EFFECT OF TRANSFER OF CONTROL ON OPTIONS. In the event of a
Transfer of Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "ACQUIRING
CORPORATION"), may either assume the Company's rights and obligations under
outstanding Options or substitute for outstanding Options substantially
equivalent options for the Acquiring Corporation's stock. For purposes of this
Section 8.2, an Option shall be deemed assumed if, following the Transfer of
Control, the Option confers the right to purchase, for each share of Stock
subject to the Option immediately prior to the Transfer of Control, the
consideration (whether stock, cash or other securities or property) to which a
holder of a share of Stock on the effective date of the Transfer of Control was
entitled. In the event the Acquiring Corporation assumes or substitutes for an
outstanding Option in connection with a Transfer of Control, no acceleration of
exercisability or vesting shall occur, unless otherwise provided in the Option
Agreement evidencing such Option or a change of control agreement between the
Company and the Optionee, if any. In the event the Acquiring Corporation elects
not to assume or substitute for outstanding Options in connection with a
Transfer of Control, any unexercisable or unvested portion of the outstanding
Options shall be immediately exercisable and vested in full as of the date ten
(10) days prior to the date of the Transfer of Control. The exercise or vesting
of any Option that was permissible solely by reason of this Section 8.2 shall be
conditioned upon the consummation of the Transfer of Control. Any Options which
are neither assumed or substituted for by the Acquiring Corporation in
connection with the Transfer of Control nor exercised as of the date of the
Transfer of Control shall terminate and cease to be outstanding effective as of
the date of the Transfer of Control. Notwithstanding the foregoing, shares
acquired upon exercise of an Option prior to the Transfer of Control and any
consideration received pursuant to the Transfer of Control with respect to such
shares shall continue to be subject to all applicable provisions of the Option
Agreement evidencing such Option except as otherwise provided in such Option
Agreement. Furthermore, notwithstanding the foregoing, if the corporation the
stock of which is subject to the outstanding Options immediately prior to an
Ownership Change Event described in Section 8.1(a)(i) constituting a Transfer of
Control is the surviving or continuing corporation and immediately after such
Ownership Change Event less than fifty percent (50%) of the total combined
voting power of its voting stock is held by another corporation or by other
corporations that are members of an affiliated group within the meaning of
Section 1504(a) of the Code without regard to the provisions of Section 1504(b)
of the Code, the outstanding Options shall not terminate unless the Board
otherwise provides in its sole discretion.

     9.   PROVISION OF INFORMATION.  Each Optionee shall be given access to
          ------------------------                                         
information concerning the Company equivalent to that information generally made
available to the Company's common stockholders.

     10.  NONTRANSFERABILITY OF INCENTIVE STOCK OPTIONS.  During the lifetime of
          ---------------------------------------------                         
the Optionee, an Option shall be exercisable only by the Optionee or the
Optionee's guardian or legal representative.  No Option shall be assignable or
transferable by the Optionee, except by will or by the laws of descent and
distribution.  Notwithstanding the foregoing, a Nonstatutory Stock Option shall
be assignable or transferable to the extent permitted by the Board and set forth
in the Option Agreement evidencing such Option.

                                       11
<PAGE>
 
     11.  INDEMNIFICATION.  In addition to such other rights of indemnification
          ---------------                                                      
as they may have as members of the Board or officers or employees of the
Participating Company Group, members of the Board and any officers or employees
of the Participating Company Group to whom authority to act for the Board or the
Company is delegated shall be indemnified by the Company against all reasonable
expenses, including attorneys' fees, actually and necessarily incurred in
connection with the defense of any action, suit or proceeding, or in connection
with any appeal therein, to which they or any of them may be a party by reason
of any action taken or failure to act under or in connection with the Plan, or
any right granted hereunder, and against all amounts paid by them in settlement
thereof (provided such settlement is approved by independent legal counsel
selected by the Company) or paid by them in satisfaction of a judgment in any
such action, suit or proceeding, except in relation to matters as to which it
shall be adjudged in such action, suit or proceeding that such person is liable
for gross negligence, bad faith or intentional misconduct in duties; provided,
however, that within sixty (60) days after the institution of such action, suit
or proceeding, such person shall offer to the Company, in writing, the
opportunity at its own expense to handle and defend the same.

     12.  TERMINATION OR AMENDMENT OF PLAN.  The Board may terminate or amend
          --------------------------------                                   
the Plan at any time.  However, subject to changes in applicable law,
regulations or rules that would permit otherwise, without the approval of the
Company's stockholders, there shall be (a) no increase in the maximum aggregate
number of shares of Stock that may be issued under the Plan (except by operation
of the provisions of Section 4.2), (b) no change in the class of persons
eligible to receive Incentive Stock Options, and (c) no other amendment of the
Plan that would require approval of the Company's stockholders under any
applicable law, regulation or rule.  In any event, no termination or amendment
of the Plan may adversely affect any then outstanding Option or any unexercised
portion thereof, without the consent of the Optionee, unless such termination or
amendment is required to enable an Option designated as an Incentive Stock
Option to qualify as an Incentive Stock Option or is necessary to comply with
any applicable law, regulation or rule.

     IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies that
the foregoing Consilium, Inc. 1996 Stock Option Plan was duly adopted by the
Board on December 13, 1996.

renders Service to the Participating Company Group or a change in the
Participating Company for which the Optionee renders such Service, provided that
there is no interruption or termination of the Optionee's Service. The
Optionee's Service shall be deemed to have terminated either upon an actual
termination of Service or upon the corporation for which the Optionee performs

ceased to be an Employee (other than by reason of death or a permanent and total
disability as defined in Section 22(e)(3) of the Code), the Option will be

          1.2  CONSTRUCTION.  Captions and titles contained herein are for
convenience only and shall not affect the meaning or interpretation of any
provision of this Option Agreement.  Except when otherwise indicated by the
context, the singular shall include the plural and the plural shall include the
singular.  Use of the term "or" is not intended to be exclusive, unless the
context clearly requires otherwise.

     2.   TAX CONSEQUENCES.
          ---------------- 

          2.1  TAX STATUS OF OPTION.  This Option is intended to be an incentive
stock option within the meaning of Section 422(b) of the Code (an "INCENTIVE
STOCK OPTION"), but the Company does not represent or warrant that this Option
qualifies as such.  The Optionee should consult with the Optionee's own tax
advisor regarding the tax effects of this Option and the requirements necessary
to obtain favorable income tax treatment under Section 422 of the Code,
including, but not limited to, holding period requirements.  (NOTE: If the
aggregate Exercise Price of the Option (that is, the Exercise Price multiplied
by the Number of Option Shares) plus the aggregate exercise price of any other
Incentive Stock Options held by the Optionee (whether granted pursuant to the
Plan or any other stock option plan of the Participating Company Group) is
greater than One Hundred Thousand Dollars ($100,000), the Optionee should
contact the Chief Financial Officer of the Company to ascertain whether the
entire Option qualifies as an Incentive Stock Option.)

          2.2  ELECTION UNDER SECTION 83(b) OF THE CODE. If the Optionee
exercises this Option to purchase shares of Stock that are both nontransferable
and subject to a substantial risk

                                       17

of forfeiture, the Optionee understands that the Optionee should consult with
the Optionee's tax advisor regarding the advisability of filing with the
Internal Revenue Service an election under Section 83(b) of the Code, which must
be filed no later than thirty (30) days after the date on which the Optionee
exercises the Option. Shares acquired upon exercise of the Option are
nontransferable and subject to a substantial risk of forfeiture if, for example,
(a) they are unvested and are subject to a right of the Company to repurchase
such shares at the Optionee's original purchase price if the Optionee's Service
terminates, or (b) the Optionee is subject to a restriction on transfer to
comply with "Pooling-of-Interests Accounting" rules. Failure to file an election
under Section 83(b), if appropriate, may result in adverse tax consequences to
the Optionee. The Optionee acknowledges that the Optionee has been advised to
consult with a tax advisor prior to the exercise of the Option regarding the tax
consequences to the Optionee of the exercise of the Option. AN ELECTION UNDER
SECTION 83(b) MUST BE FILED WITHIN 30 DAYS AFTER THE DATE ON WHICH THE OPTIONEE
PURCHASES SHARES. THIS TIME PERIOD CANNOT BE EXTENDED. THE OPTIONEE ACKNOWLEDGES
THAT TIMELY FILING OF A SECTION 83(b) ELECTION IS THE OPTIONEE'S SOLE
RESPONSIBILITY, EVEN IF THE OPTIONEE REQUESTS THE COMPANY OR ITS REPRESENTATIVE
TO FILE SUCH ELECTION ON HIS OR HER BEHALF.

     3.   ADMINISTRATION.  All questions of interpretation concerning this
          --------------                                                  
Option Agreement shall be determined by the Board, including any duly appointed
Committee of the Board.  All determinations by the Board shall be final and
binding upon all persons having an interest in the Option.  Any officer of a
Participating Company shall have the authority to act on behalf of the Company
with respect to any matter, right, obligation, or election which is the
responsibility of or which is allocated to the Company herein, provided the
officer has apparent authority with respect to such matter, right, obligation,
or election.

     4.   EXERCISE OF THE OPTION.
          ---------------------- 

          4.1  RIGHT TO EXERCISE. Except as otherwise provided herein, the
Option shall be exercisable on and after the Initial Exercise Date and prior to
the termination of the Option (as provided in Section 6) in an amount not to
exceed the Number of Option Shares multiplied by the Vested Ratio less the
number of shares previously acquired upon exercise of the Option. In no event
shall the Option be exercisable for more shares than the Number of Option
Shares.

          4.2  METHOD OF EXERCISE. Exercise of the Option shall be by written
notice to the Company which must state the election to exercise the Option, the
number of whole shares of Stock for which the Option is being exercised and such
other representations and agreements as to the Optionee's investment intent with
respect to such shares as may be required pursuant to the provisions of this
Option Agreement. The written notice must be signed by the Optionee and must be
delivered in person, by certified or registered mail, return receipt requested,
by confirmed facsimile transmission, or by such other means as the Company may
permit, to the Chief Financial Officer of the Company, or other authorized
representative of the Participating Company Group, prior to the termination of
the Option as set forth in Section 6, accompanied by full payment of the
aggregate Exercise Price for the number of shares of Stock being purchased.

                                       18
<PAGE>
 
The Option shall be deemed to be exercised upon receipt by the Company of such
written notice and the aggregate Exercise Price.

          4.3  PAYMENT OF EXERCISE PRICE.

               (a)  FORMS OF CONSIDERATION AUTHORIZED. Except as otherwise
provided below, payment of the aggregate Exercise Price for the number of shares
of Stock for which the Option is being exercised shall be made (i) in cash, by
check, or cash equivalent, (ii) by tender to the Company of whole shares of
Stock owned by the Optionee having a Fair Market Value (as determined by the
Company without regard to any restrictions on transferability applicable to such
stock by reason of federal or state securities laws or agreements with an
underwriter for the Company) not less than the aggregate Exercise Price, (iii)
by means of a Cashless Exercise, as defined in Section 4.3(c), or (iv) by any
combination of the foregoing.

               (b)  TENDER OF STOCK. Notwithstanding the foregoing, the Option
may not be exercised by tender to the Company of shares of Stock to the extent
such tender of Stock would constitute a violation of the provisions of any law,
regulation or agreement restricting the redemption of the Company's stock. The
Option may not be exercised by tender to the Company of shares of Stock unless
such shares either have been owned by the Optionee for more than six (6) months
or were not acquired, directly or indirectly, from the Company.

               (c)  CASHLESS EXERCISE. A "CASHLESS EXERCISE" means the
assignment in a form acceptable to the Company of the proceeds of a sale or loan
with respect to some or all of the shares of Stock acquired upon the exercise of
the Option pursuant to a program or procedure approved by the Company
(including, without limitation, through an exercise complying with the
provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System). The Company reserves, at any and all
times, the right, in the Company's sole and absolute discretion, to decline to
approve or terminate any such program or procedure.

          4.4  TAX WITHHOLDING. At the time the Option is exercised, in whole or
in part, or at any time thereafter as requested by the Company, the Optionee
hereby authorizes withholding from payroll and any other amounts payable to the
Optionee, and otherwise agrees to make adequate provision for (including by
means of a Cashless Exercise to the extent permitted by the Company), any sums
required to satisfy the federal, state, local and foreign tax withholding
obligations of the Participating Company Group, if any, which arise in
connection with the Option, including, without limitation, obligations arising
upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in
whole or in part, of any shares acquired upon exercise of the Option, (iii) the
operation of any law or regulation providing for the imputation of interest, or
(iv) the lapsing of any restriction with respect to any shares acquired upon
exercise of the Option. The Optionee is cautioned that the Option is not
exercisable unless the tax withholding obligations of the Participating Company
Group are satisfied. Accordingly, the Optionee may not be able to exercise the
Option when desired even though the Option is vested, and the Company shall have
no obligation to issue a certificate for such shares or release such shares from
any escrow provided for herein.

                                       19
<PAGE>
 
          4.5  CERTIFICATE REGISTRATION. Except in the event the Exercise Price
is paid by means of a Cashless Exercise, the certificate for the shares as to
which the Option is exercised shall be registered in the name of the Optionee,
or, if applicable, in the names of the heirs of the Optionee.

          4.6  RESTRICTIONS ON GRANT OF THE OPTION AND ISSUANCE OF SHARES. The
grant of the Option and the issuance of shares of Stock upon exercise of the
Option shall be subject to compliance with all applicable requirements of
federal, state or foreign law with respect to such securities. The Option may
not be exercised if the issuance of shares of Stock upon exercise would
constitute a violation of any applicable federal, state or foreign securities
laws or other law or regulations or the requirements of any stock exchange or
market system upon which the Stock may then be listed. In addition, the Option
may not be exercised unless (i) a registration statement under the Securities
Act shall at the time of exercise of the Option be in effect with respect to the
shares issuable upon exercise of the Option or (ii) in the opinion of legal
counsel to the Company, the shares issuable upon exercise of the Option may be
issued in accordance with the terms of an applicable exemption from the
registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT
THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED.
ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED
EVEN THOUGH THE OPTION IS VESTED. Questions concerning this restriction should
be directed to the Chief Financial Officer of the Company. The inability of the
Company to obtain from any regulatory body having jurisdiction the authority, if
any, deemed by the Company's legal counsel to be necessary to the lawful
issuance and sale of any shares subject to the Option shall relieve the Company
of any liability in respect of the failure to issue or sell such shares as to
which such requisite authority shall not have been obtained. As a condition to
the exercise of the Option, the Company may require the Optionee to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with
any applicable law or regulation and to make any representation or warranty with
respect thereto as may be requested by the Company.

          4.7  FRACTIONAL SHARES.  The Company shall not be required to issue
fractional shares upon the exercise of the Option.

     5.   NONTRANSFERABILITY OF THE OPTION.  The Option may be exercised during
          --------------------------------                                     
the lifetime of the Optionee only by the Optionee or the Optionee's guardian or
legal representative and may not be assigned or transferred in any manner except
by will or by the laws of descent and distribution.  Following the death of the
Optionee, the Option, to the extent provided in Section 7, may be exercised by
the Optionee's legal representative or by any person empowered to do so under
the deceased Optionee's will or under the then applicable laws of descent and
distribution.

     6.   TERMINATION OF THE OPTION.  The Option shall terminate and may no
          -------------------------                                        
longer be exercised on the first to occur of (a) the Option Expiration Date, (b)
the last date for exercising the Option following termination of the Optionee's
Service as described in Section 7, or (c) a Transfer of Control to the extent
provided in Section 8.

                                       20
<PAGE>
 
     7.   EFFECT OF TERMINATION OF SERVICE.
          -------------------------------- 

          7.1  OPTION EXERCISABILITY.

               (a)  DISABILITY. If the Optionee's Service with the Participating
Company Group is terminated because of the Disability of the Optionee, the
Option, to the extent unexercised and exercisable on the date on which the
Optionee's Service terminated, may be exercised by the Optionee (or the
Optionee's guardian or legal representative) at any time prior to the expiration
of twelve (12) months after the date on which the Optionee's Service terminated,
but in any event no later than the Option Expiration Date.

               (b)  DEATH. If the Optionee's Service with the Participating
Company Group is terminated because of the death of the Optionee, the Option, to
the extent unexercised and exercisable on the date on which the Optionee's
Service terminated, may be exercised by the Optionee's legal representative or
other person who acquired the right to exercise the Option by reason of the
Optionee's death at any time prior to the expiration of twelve (12) months after
the date on which the Optionee's Service terminated, but in any event no later
than the Option Expiration Date. The Optionee's Service shall be deemed to have
terminated on account of death if the Optionee dies within three (3) months
after the Optionee's termination of Service.

               (c)  OTHER TERMINATION OF SERVICE. If the Optionee's Service with
the Participating Company Group terminates for any reason, except Disability or
death, the Option, to the extent unexercised and exercisable by the Optionee on
the date on which the Optionee's Service terminated, may be exercised by the
Optionee within three (3) months (or such other longer period of time as
determined by the Board, in its sole discretion) after the date on which the
Optionee's Service terminated, but in any event no later than the Option
Expiration Date.

          7.2  EXTENSION IF EXERCISE PREVENTED BY LAW.  Notwithstanding the
foregoing, if the exercise of the Option within the applicable time periods set
forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option
shall remain exercisable until three (3) months after the date the Optionee is
notified by the Company that the Option is exercisable, but in any event no
later than the Option Expiration Date.  The Company makes no representation as
to the tax consequences of any such delayed exercise.  The Optionee should
consult with the Optionee's own tax advisor as to the tax consequences to the
Optionee of any such delayed exercise.

          7.3  EXTENSION IF OPTIONEE SUBJECT TO SECTION 16(b). Notwithstanding
the foregoing, if a sale within the applicable time periods set forth in Section
7.1 of shares acquired upon the exercise of the Option would subject the
Optionee to suit under Section 16(b) of the Exchange Act, the Option shall
remain exercisable until the earliest to occur of (i) the tenth (10th) day
following the date on which a sale of such shares by the Optionee would no
longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day
after the Optionee's termination of Service, or (iii) the Option Expiration
Date. The Company makes no representation as to the tax consequences of any such
delayed exercise. The Optionee should

                                       21
<PAGE>
 
consult with the Optionee's own tax advisors as to the tax consequences to the
Optionee of any such delayed exercise.

          7.4  LEAVE OF ABSENCE. For purposes of Section 7.1, the Optionee's
Service with the Participating Company Group shall not be deemed to terminate if
the Optionee takes any military leave, sick leave, or other bona fide leave of
absence approved by the Company of ninety (90) days or less. In the event of a
leave of absence in excess of ninety (90) days, the Optionee's Service shall be
deemed to terminate on the ninety-first (91st) day of such leave unless the
Optionee's right to return to Service with the Participating Company Group
remains guaranteed by statute or contract. Notwithstanding the foregoing, unless
otherwise designated by the Company (or required by law), a leave of absence
shall not be treated as Service for purposes of determining the Optionee's
Vested Ratio.

     8.   TRANSFER OF CONTROL.
          ------------------- 

          8.1  DEFINITIONS.

               (a)  An "OWNERSHIP CHANGE EVENT" shall be deemed to have occurred
if any of the following occurs with respect to the Company:

                    (i)   the direct or indirect sale or exchange in a single or
series of related transactions by the stockholders of the Company of more than
fifty percent (50%) of the voting stock of the Company;

                    (ii)  a merger or consolidation in which the Company is a
party;

                    (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or

                    (iv)  a liquidation or dissolution of the Company.

               (b)  A "TRANSFER OF CONTROL" shall mean an Ownership Change Event
or a series of related Ownership Change Events (collectively, the "TRANSACTION")
wherein the stockholders of the Company immediately before the Transaction do
not retain immediately after the Transaction, in substantially the same
proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "TRANSFEREE
CORPORATION(S)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the

                                       22
<PAGE>
 
Company or multiple Ownership Change Events are related, and its determination
shall be final, binding and conclusive.

          8.2  EFFECT OF TRANSFER OF CONTROL ON OPTION. In the event of a
Transfer of Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "ACQUIRING
CORPORATION"), may either assume the Company's rights and obligations under the
Option or substitute for the Option a substantially equivalent option for the
Acquiring Corporation's stock. For purposes of this Section 8.2, an Option shall
be deemed assumed if, following the Transfer of Control, the Option confers the
right to purchase, for each share of Stock subject to the Option immediately
prior to the Transfer of Control, the consideration (whether stock, cash or
other securities or property) to which a holder of a share of Stock on the
effective date of the Transfer of Control was entitled. In the event the
Acquiring Corporation elects not to assume the Company's rights and obligations
under the Option or substitute for the Option in connection with the Transfer of
Control, any unexercised portion of the Option shall be immediately exercisable
and vested in full as of the date ten (10) days prior to the date of the
Transfer of Control. Any exercise of the Option that was permissible solely by
reason of this Section 8.2 shall be conditioned upon the consummation of the
Transfer of Control. The Option shall terminate and cease to be outstanding
effective as of the date of the Transfer of Control to the extent that the
Option is neither assumed or substituted for by the Acquiring Corporation in
connection with the Transfer of Control nor exercised as of the date of the
Transfer of Control. Notwithstanding the foregoing, shares acquired upon
exercise of the Option prior to the Transfer of Control and any consideration
received pursuant to the Transfer of Control with respect to such shares shall
continue to be subject to all applicable provisions of this Option Agreement
except as otherwise provided herein. Furthermore, notwithstanding the foregoing,
if the corporation the stock of which is subject to the Option immediately prior
to an Ownership Change Event described in Section 8.1(a)(i) constituting a
Transfer of Control is the surviving or continuing corporation and immediately
after such Ownership Change Event less than fifty percent (50%) of the total
combined voting power of its voting stock is held by another corporation or by
other corporations that are members of an affiliated group within the meaning of
Section 1504(a) of the Code without regard to the provisions of Section 1504(b)
of the Code, the Option shall not terminate unless the Board otherwise provides
in its sole discretion.

          8.3  FAIR MARKET VALUE LIMITATION.  Should the exercisability of this
Option be accelerated in connection with a Transfer of Control in accordance
with Section 8.2, then to the extent that the aggregate Fair Market Value of the
shares of Stock with respect to which the Optionee may exercise the Option for
the first time during the calendar year of the Transfer of Control, when added
to the aggregate Fair Market Value of the shares subject to any other options
designated as Incentive Stock Options granted to the Optionee under all stock
option plans of the Participating Company Group prior to the Date of Option
Grant with respect to which such options are exercisable for the first time
during the same calendar year, exceeds One Hundred Thousand Dollars ($100,000)
(or such other limit, if any, imposed by Section 422 of the Code), the portion
of the Option which exceeds such amount shall be treated as a Nonstatutory Stock
Option.  For purposes of the preceding sentence, options designated as Incentive
Stock Options shall be taken into account in the order in which they were
granted, and the Fair Market 

                                       23
<PAGE>
 
Value of shares of stock shall be determined as of the time the option with
respect to such shares is granted.

     9.   ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.  In the event of any
          --------------------------------------------                      
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification, or similar change in the capital structure of the Company,
appropriate adjustments shall be made in the number, Exercise Price and class of
shares of stock subject to the Option.  If a majority of the shares which are of
the same class as the shares that are subject to the Option are exchanged for,
converted into, or otherwise become (whether or not pursuant to an Ownership
Change Event) shares of another corporation (the "NEW SHARES"), the Board may
unilaterally amend the Option to provide that the Option is exercisable for New
Shares.  In the event of any such amendment, the Number of Option Shares and the
Exercise Price shall be adjusted in a fair and equitable manner, as determined
by the Board, in its sole discretion.  Notwithstanding the foregoing, any
fractional share resulting from an adjustment pursuant to this Section 9 shall
be rounded up or down to the nearest whole number, as determined by the Board,
and in no event may the Exercise Price be decreased to an amount less than the
par value, if any, of the stock subject to the Option.  The adjustments
determined by the Board pursuant to this Section 9 shall be final, binding and
conclusive.

     10.  RIGHTS AS A STOCKHOLDER, EMPLOYEE OR CONSULTANT.  The Optionee shall
          -----------------------------------------------                     
have no rights as a stockholder with respect to any shares covered by the Option
until the date of the issuance of a certificate for the shares for which the
Option has been exercised (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company).  No
adjustment shall be made for dividends, distributions or other rights for which
the record date is prior to the date such certificate is issued, except as
provided in Section 9.  Nothing in this Option Agreement shall confer upon the
Optionee any right to continue in the Service of a Participating Company or
interfere in any way with any right of the Participating Company Group to
terminate the Optionee's Service as an Employee or Consultant, as the case may
be, at any time.

     11.  NOTICE OF SALES UPON DISQUALIFYING DISPOSITION.  The Optionee shall
          ----------------------------------------------                     
dispose of the shares acquired pursuant to the Option only in accordance with
the provisions of this Option Agreement.  In addition, the Optionee shall
promptly notify the Chief Financial Officer of the Company if the Optionee
disposes of any of the shares acquired pursuant to the Option within one (1)
year after the date the Optionee exercises all or part of the Option or within
two (2) years after the Date of Option Grant and shall provide the Company with
a description of the terms and circumstances of such disposition.  Until such
time as the Optionee disposes of such shares in a manner consistent with the
provisions of this Option Agreement, unless otherwise expressly authorized by
the Company, the Optionee shall hold all shares acquired pursuant to the Option
in the Optionee's name (and not in the name of any nominee) for the one-year
period immediately after the exercise of the Option and the two-year period
immediately after Date of Option Grant.  At any time during the one-year or two-
year periods set forth above, the Company may place a legend on any certificate
representing shares acquired pursuant to the Option requesting the transfer
agent for the Company's stock to notify the Company of any such transfers.  The
obligation of the Optionee to notify the Company of any such transfer shall
continue 

                                       24
<PAGE>
 
notwithstanding that a legend has been placed on the certificate pursuant to the
preceding sentence.

     12.  LEGENDS.  The Company may at any time place legends referencing any
          -------                                                            
applicable federal, state or foreign securities law restrictions on all
certificates representing shares of stock subject to the provisions of this
Option Agreement.  The Optionee shall, at the request of the Company, promptly
present to the Company any and all certificates representing shares acquired
pursuant to the Option in the possession of the Optionee in order to carry out
the provisions of this Section.

     13.  RESTRICTIONS ON TRANSFER OF SHARES.  No shares acquired upon exercise
          ----------------------------------                                   
of the Option may be sold, exchanged, transferred (including, without
limitation, any transfer to a nominee or agent of the Optionee), assigned,
pledged, hypothecated or otherwise disposed of, including by operation of law,
in any manner which violates any of the provisions of this Option Agreement, and
any such attempted disposition shall be void.  The Company shall not be required
(a) to transfer on its books any shares which will have been transferred in
violation of any of the provisions set forth in this Option Agreement or (b) to
treat as owner of such shares or to accord the right to vote as such owner or to
pay dividends to any transferee to whom such shares will have been so
transferred.

     14.  BINDING EFFECT.  Subject to the restrictions on transfer set forth
          --------------                                                    
herein, this Option Agreement shall inure to the benefit of and be binding upon
the parties hereto and their respective heirs, executors, administrators,
successors and assigns.

     15.  TERMINATION OR AMENDMENT.  The Board may terminate or amend the Plan
          ------------------------                                            
or the Option at any time; provided, however, that except as provided in Section
8.2 in connection with a Transfer of Control, no such termination or amendment
may adversely affect the Option or any unexercised portion hereof without the
consent of the Optionee unless such termination or amendment is necessary to
comply with any applicable law or government regulation or is required to enable
the Option to qualify as an Incentive Stock Option.  No amendment or addition to
this Option Agreement shall be effective unless in writing.

     16.  INTEGRATED AGREEMENT.  This Option Agreement constitutes the entire
          --------------------                                               
understanding and agreement of the Optionee and the Participating Company Group
with respect to the subject matter contained herein, and there are no
agreements, understandings, restrictions, representations, or warranties among
the Optionee and the Participating Company Group with respect to such subject
matter other than those as set forth or provided for herein, except for the
provisions set forth in a change of control agreement between the Company and
the Optionee, if any.  To the extent contemplated herein, the provisions of this
Option Agreement shall survive any exercise of the Option and shall remain in
full force and effect.

     17.  APPLICABLE LAW.  This Option Agreement shall be governed by the laws
          --------------                                                      
of the State of California as such laws are applied to agreements between
California residents entered into and to be performed entirely within the State
of California.

renders Service to the Participating Company Group or a change in the
Participating Company for which the Optionee renders such Service, provided that
there is no interruption or termination of the Optionee's Service. The
Optionee's Service shall be deemed to have terminated either upon an actual

          1.2  CONSTRUCTION.  Captions and titles contained herein are for

context clearly requires otherwise.

     2.   TAX CONSEQUENCES.
          ---------------- 

          2.1  TAX STATUS OF OPTION.  This Option is intended to be an incentive
stock option within the meaning of Section 422(b) of the Code (an "INCENTIVE
STOCK OPTION"), but the Company does not represent or warrant that this Option
qualifies as such.  The Optionee should consult with the Optionee's own tax
advisor regarding the tax effects of this Option and the requirements necessary
to obtain favorable income tax treatment under Section 422 of the Code,
including, but not limited to, holding period requirements.  (NOTE: If the
aggregate Exercise Price of the Option (that is, the Exercise Price multiplied
by the Number of Option Shares) plus the aggregate exercise price of any other
Incentive Stock Options held by the Optionee (whether granted pursuant to the
Plan or any other stock option plan of the Participating Company Group) is
greater than One Hundred Thousand Dollars ($100,000), the Optionee should
contact the Chief Financial Officer of the Company to ascertain whether the
entire Option qualifies as an Incentive Stock Option.)

          2.2  ELECTION UNDER SECTION 83(B) OF THE CODE. If the Optionee
exercises this Option to purchase shares of Stock that are both nontransferable
and subject to a substantial risk of forfeiture, the Optionee understands that
the Optionee should consult with the Optionee's tax advisor regarding the
advisability of filing with the Internal Revenue Service an election under
Section 83(b) of the Code, which must be filed no later than thirty (30) days
after the date on which the Optionee exercises the Option. Shares acquired upon
exercise of the Option are nontransferable and subject to a substantial risk of
forfeiture if, for example, (a) they are unvested and are subject to a right of
the Company to repurchase such shares at the Optionee's original purchase price
if the Optionee's Service terminates, or (b) the Optionee is subject to a
restriction on transfer to comply with "Pooling-of-Interests Accounting" rules.
Failure to file an election under Section 83(b), if appropriate, may result in
adverse tax consequences to the Optionee. The Optionee acknowledges that the
Optionee has been advised to consult with a tax advisor prior to the exercise of
the Option regarding the tax consequences to the Optionee of the exercise of the
Option. AN ELECTION UNDER SECTION 83(b) MUST BE FILED WITHIN 30 DAYS AFTER THE
DATE ON WHICH THE OPTIONEE PURCHASES SHARES. THIS TIME PERIOD CANNOT BE
EXTENDED. THE OPTIONEE ACKNOWLEDGES THAT TIMELY FILING OF A SECTION 83(b)
ELECTION IS THE OPTIONEE'S SOLE RESPONSIBILITY, EVEN IF THE OPTIONEE REQUESTS
THE COMPANY OR ITS REPRESENTATIVE TO FILE SUCH ELECTION ON HIS OR HER BEHALF.

     3.   ADMINISTRATION.  All questions of interpretation concerning this
          --------------                                                  
Option Agreement shall be determined by the Board, including any duly appointed
Committee of the Board.  All determinations by the Board shall be final and
binding upon all persons having an interest in the Option.  Any officer of a
Participating Company shall have the authority to act on behalf of the Company
with respect to any matter, right, obligation, or election which is the
responsibility of or which is allocated to the Company herein, provided the
officer has apparent authority with respect to such matter, right, obligation,
or election.

     4.   EXERCISE OF THE OPTION.
          ---------------------- 

          4.1  RIGHT TO EXERCISE. Except as otherwise provided herein, the
Option shall be exercisable on and after the Initial Exercise Date and prior to
the termination of the Option (as provided in Section 6) in an amount not to
exceed the Number of Option Shares multiplied by the Vested Ratio less the
number of shares previously acquired upon exercise of the Option. In no event
shall the Option be exercisable for more shares than the Number of Option
Shares.

          4.2  METHOD OF EXERCISE. Exercise of the Option shall be by written
notice to the Company which must state the election to exercise the Option, the
number of whole shares of Stock for which the Option is being exercised and such
other representations and agreements as to the Optionee's investment intent with
respect to such shares as may be required pursuant to the provisions of this
Option Agreement. The written notice must be signed by the Optionee and must be
delivered in person, by certified or registered mail, return receipt requested,
by confirmed facsimile transmission, or by such other means as the Company may
permit, to the Chief Financial Officer of the Company, or other authorized
representative of the Participating

                                       31
<PAGE>
 
Company Group, prior to the termination of the Option as set forth in Section 6,
accompanied by full payment of the aggregate Exercise Price for the number of
shares of Stock being purchased. The Option shall be deemed to be exercised upon
receipt by the Company of such written notice and the aggregate Exercise Price.

          4.3  PAYMENT OF EXERCISE PRICE.

               (a)  FORMS OF CONSIDERATION AUTHORIZED. Except as otherwise
provided below, payment of the aggregate Exercise Price for the number of shares
of Stock for which the Option is being exercised shall be made (i) in cash, by
check, or cash equivalent, (ii) by tender to the Company of whole shares of
Stock owned by the Optionee having a Fair Market Value (as determined by the
Company without regard to any restrictions on transferability applicable to such
stock by reason of federal or state securities laws or agreements with an
underwriter for the Company) not less than the aggregate Exercise Price, (iii)
by means of a Cashless Exercise, as defined in Section 4.3(c), or (iv) by any
combination of the foregoing.

               (b)  TENDER OF STOCK. Notwithstanding the foregoing, the Option
may not be exercised by tender to the Company of shares of Stock to the extent
such tender of Stock would constitute a violation of the provisions of any law,
regulation or agreement restricting the redemption of the Company's stock. The
Option may not be exercised by tender to the Company of shares of Stock unless
such shares either have been owned by the Optionee for more than six (6) months
or were not acquired, directly or indirectly, from the Company.

               (c)  CASHLESS EXERCISE. A "CASHLESS EXERCISE" means the
assignment in a form acceptable to the Company of the proceeds of a sale or loan
with respect to some or all of the shares of Stock acquired upon the exercise of
the Option pursuant to a program or procedure approved by the Company
(including, without limitation, through an exercise complying with the
provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System). The Company reserves, at any and all
times, the right, in the Company's sole and absolute discretion, to decline to
approve or terminate any such program or procedure.

          4.4  TAX WITHHOLDING. At the time the Option is exercised, in whole or
in part, or at any time thereafter as requested by the Company, the Optionee
hereby authorizes withholding from payroll and any other amounts payable to the
Optionee, and otherwise agrees to make adequate provision for (including by
means of a Cashless Exercise to the extent permitted by the Company), any sums
required to satisfy the federal, state, local and foreign tax withholding
obligations of the Participating Company Group, if any, which arise in
connection with the Option, including, without limitation, obligations arising
upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in
whole or in part, of any shares acquired upon exercise of the Option, (iii) the
operation of any law or regulation providing for the imputation of interest, or
(iv) the lapsing of any restriction with respect to any shares acquired upon
exercise of the Option. The Optionee is cautioned that the Option is not
exercisable unless the tax withholding obligations of the Participating Company
Group are satisfied. Accordingly, the

                                       32
<PAGE>
 
Optionee may not be able to exercise the Option when desired even though the
Option is vested, and the Company shall have no obligation to issue a
certificate for such shares or release such shares from any escrow provided for
herein.

          4.5  CERTIFICATE REGISTRATION. Except in the event the Exercise Price
is paid by means of a Cashless Exercise, the certificate for the shares as to
which the Option is exercised shall be registered in the name of the Optionee,
or, if applicable, in the names of the heirs of the Optionee.

          4.6  RESTRICTIONS ON GRANT OF THE OPTION AND ISSUANCE OF SHARES. The
grant of the Option and the issuance of shares of Stock upon exercise of the
Option shall be subject to compliance with all applicable requirements of
federal, state or foreign law with respect to such securities. The Option may
not be exercised if the issuance of shares of Stock upon exercise would
constitute a violation of any applicable federal, state or foreign securities
laws or other law or regulations or the requirements of any stock exchange or
market system upon which the Stock may then be listed. In addition, the Option
may not be exercised unless (i) a registration statement under the Securities
Act shall at the time of exercise of the Option be in effect with respect to the
shares issuable upon exercise of the Option or (ii) in the opinion of legal
counsel to the Company, the shares issuable upon exercise of the Option may be
issued in accordance with the terms of an applicable exemption from the
registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT
THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED.
ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED
EVEN THOUGH THE OPTION IS VESTED. Questions concerning this restriction should
be directed to the Chief Financial Officer of the Company. The inability of the
Company to obtain from any regulatory body having jurisdiction the authority, if
any, deemed by the Company's legal counsel to be necessary to the lawful
issuance and sale of any shares subject to the Option shall relieve the Company
of any liability in respect of the failure to issue or sell such shares as to
which such requisite authority shall not have been obtained. As a condition to
the exercise of the Option, the Company may require the Optionee to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with
any applicable law or regulation and to make any representation or warranty with
respect thereto as may be requested by the Company.

          4.7  FRACTIONAL SHARES.  The Company shall not be required to issue
fractional shares upon the exercise of the Option.

     5.   NONTRANSFERABILITY OF THE OPTION.  The Option may be exercised during
          --------------------------------                                     
the lifetime of the Optionee only by the Optionee or the Optionee's guardian or
legal representative and may not be assigned or transferred in any manner except
by will or by the laws of descent and distribution.  Following the death of the
Optionee, the Option, to the extent provided in Section 7, may be exercised by
the Optionee's legal representative or by any person empowered to do so under
the deceased Optionee's will or under the then applicable laws of descent and
distribution.

                                       33

     6.   TERMINATION OF THE OPTION.  The Option shall terminate and may no
          -------------------------                                        
longer be exercised on the first to occur of (a) the Option Expiration Date, (b)
the last date for exercising the Option following termination of the Optionee's
Service as described in Section 7, or (c) a Transfer of Control to the extent
provided in Section 8.

     7.   EFFECT OF TERMINATION OF SERVICE.
          -------------------------------- 

          7.1  OPTION EXERCISABILITY.

               (a)  DISABILITY. If the Optionee's Service with the Participating
Company Group is terminated because of the Disability of the Optionee, the
Option, to the extent unexercised and exercisable on the date on which the
Optionee's Service terminated, may be exercised by the Optionee (or the
Optionee's guardian or legal representative) at any time prior to the expiration
of twelve (12) months after the date on which the Optionee's Service terminated,
but in any event no later than the Option Expiration Date.

               (b)  DEATH. If the Optionee's Service with the Participating
Company Group is terminated because of the death of the Optionee, the Option, to
the extent unexercised and exercisable on the date on which the Optionee's
Service terminated, may be exercised by the Optionee's legal representative or
other person who acquired the right to exercise the Option by reason of the
Optionee's death at any time prior to the expiration of twelve (12) months after
the date on which the Optionee's Service terminated, but in any event no later
than the Option Expiration Date. The Optionee's Service shall be deemed to have
terminated on account of death if the Optionee dies within three (3) months
after the Optionee's termination of Service.

               (c)  OTHER TERMINATION OF SERVICE. If the Optionee's Service with
the Participating Company Group terminates for any reason, except Disability or
death, the Option, to the extent unexercised and exercisable by the Optionee on
the date on which the Optionee's Service terminated, may be exercised by the
Optionee within three (3) months (or such other longer period of time as
determined by the Board, in its sole discretion) after the date on which the
Optionee's Service terminated, but in any event no later than the Option
Expiration Date.

          7.2  EXTENSION IF EXERCISE PREVENTED BY LAW.  Notwithstanding the
foregoing, if the exercise of the Option within the applicable time periods set
forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option
shall remain exercisable until three (3) months after the date the Optionee is
notified by the Company that the Option is exercisable, but in any event no
later than the Option Expiration Date.  The Company makes no representation as
to the tax consequences of any such delayed exercise.  The Optionee should
consult with the Optionee's own tax advisor as to the tax consequences to the
Optionee of any such delayed exercise.

          7.3  EXTENSION IF OPTIONEE SUBJECT TO SECTION 16(B). Notwithstanding
the foregoing, if a sale within the applicable time periods set forth in Section
7.1 of shares acquired upon the exercise of the Option would subject the
Optionee to suit under Section 16(b) of the

                                       34
<PAGE>
 
Exchange Act, the Option shall remain exercisable until the earliest to occur of
(i) the tenth (10th) day following the date on which a sale of such shares by
the Optionee would no longer be subject to such suit, (ii) the one hundred and
ninetieth (190th) day after the Optionee's termination of Service, or (iii) the
Option Expiration Date. The Company makes no representation as to the tax
consequences of any such delayed exercise. The Optionee should consult with the
Optionee's own tax advisors as to the tax consequences to the Optionee of any
such delayed exercise.

          7.4  LEAVE OF ABSENCE. For purposes of Section 7.1, the Optionee's
Service with the Participating Company Group shall not be deemed to terminate if
the Optionee takes any military leave, sick leave, or other bona fide leave of
absence approved by the Company of ninety (90) days or less. In the event of a
leave of absence in excess of ninety (90) days, the Optionee's Service shall be
deemed to terminate on the ninety-first (91st) day of such leave unless the
Optionee's right to return to Service with the Participating Company Group
remains guaranteed by statute or contract. Notwithstanding the foregoing, unless
otherwise designated by the Company (or required by law), a leave of absence
shall not be treated as Service for purposes of determining the Optionee's
Vested Ratio.

     8.   TRANSFER OF CONTROL.
          ------------------- 

          8.1  DEFINITIONS.

               (a)  An "OWNERSHIP CHANGE EVENT" shall be deemed to have occurred

                    (i)   the direct or indirect sale or exchange in a single or
series of related transactions by the stockholders of the Company of more than
fifty percent (50%) of the voting stock of the Company;

                    (ii)  a merger or consolidation in which the Company is a
party;

                    (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or

                    (iv)  a liquidation or dissolution of the Company.

               (b)  A "TRANSFER OF CONTROL" shall mean an Ownership Change Event
or a series of related Ownership Change Events (collectively, the "TRANSACTION")
wherein the stockholders of the Company immediately before the Transaction do
not retain immediately after the Transaction, in substantially the same
proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "TRANSFEREE
CORPORATION(S)"), as the case may be. For

                                       35
<PAGE>
 
purposes of the preceding sentence, indirect beneficial ownership shall include,
without limitation, an interest resulting from ownership of the voting stock of
one or more corporations which, as a result of the Transaction, own the Company
or the Transferee Corporation(s), as the case may be, either directly or through
one or more subsidiary corporations. The Board shall have the right to determine
whether multiple sales or exchanges of the voting stock of the Company or
multiple Ownership Change Events are related, and its determination shall be
final, binding and conclusive.

          8.2  EFFECT OF TRANSFER OF CONTROL ON OPTION. In the event of a
Transfer of Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "ACQUIRING
CORPORATION"), may either assume the Company's rights and obligations under the
Option or substitute for the Option a substantially equivalent option for the
Acquiring Corporation's stock. For purposes of this Section 8.2, an Option shall
be deemed assumed if, following the Transfer of Control, the Option confers the
right to purchase, for each share of Stock subject to the Option immediately
prior to the Transfer of Control, the consideration (whether stock, cash or
other securities or property) to which a holder of a share of Stock on the
effective date of the Transfer of Control was entitled. In the event the
Acquiring Corporation elects not to assume the Company's rights and obligations
under the Option or substitute for the Option in connection with the Transfer of
Control, any unexercised portion of the Option shall be immediately exercisable
and vested in full as of the date ten (10) days prior to the date of the
Transfer of Control. Any exercise of the Option that was permissible solely by
reason of this Section 8.2 shall be conditioned upon the consummation of the
Transfer of Control. The Option shall terminate and cease to be outstanding
effective as of the date of the Transfer of Control to the extent that the
Option is neither assumed or substituted for by the Acquiring Corporation in
connection with the Transfer of Control nor exercised as of the date of the
Transfer of Control. Notwithstanding the foregoing, shares acquired upon
exercise of the Option prior to the Transfer of Control and any consideration
received pursuant to the Transfer of Control with respect to such shares shall
continue to be subject to all applicable provisions of this Option Agreement
except as otherwise provided herein. Furthermore, notwithstanding the foregoing,
if the corporation the stock of which is subject to the Option immediately prior
to an Ownership Change Event described in Section 8.1(a)(i) constituting a
Transfer of Control is the surviving or continuing corporation and immediately
after such Ownership Change Event less than fifty percent (50%) of the total
combined voting power of its voting stock is held by another corporation or by
other corporations that are members of an affiliated group within the meaning of
Section 1504(a) of the Code without regard to the provisions of Section 1504(b)
of the Code, the Option shall not terminate unless the Board otherwise provides
in its sole discretion.

          8.3  FAIR MARKET VALUE LIMITATION.  Should the exercisability of this
Option be accelerated in connection with a Transfer of Control in accordance
with Section 8.2, then to the extent that the aggregate Fair Market Value of the
shares of Stock with respect to which the Optionee may exercise the Option for
the first time during the calendar year of the Transfer of Control, when added
to the aggregate Fair Market Value of the shares subject to any other options
designated as Incentive Stock Options granted to the Optionee under all stock
option plans of the Participating Company Group prior to the Date of Option
Grant with respect to 

                                       36
<PAGE>
 
which such options are exercisable for the first time during the same calendar
year, exceeds One Hundred Thousand Dollars ($100,000) (or such other limit, if
any, imposed by Section 422 of the Code), the portion of the Option which
exceeds such amount shall be treated as a Nonstatutory Stock Option. For
purposes of the preceding sentence, options designated as Incentive Stock
Options shall be taken into account in the order in which they were granted, and
the Fair Market Value of shares of stock shall be determined as of the time the
option with respect to such shares is granted.

     9.   ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.  In the event of any
          --------------------------------------------                      
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification, or similar change in the capital structure of the Company,
appropriate adjustments shall be made in the number, Exercise Price and class of
shares of stock subject to the Option.  If a majority of the shares which are of
the same class as the shares that are subject to the Option are exchanged for,
converted into, or otherwise become (whether or not pursuant to an Ownership
Change Event) shares of another corporation (the "NEW SHARES"), the Board may
unilaterally amend the Option to provide that the Option is exercisable for New
Shares.  In the event of any such amendment, the Number of Option Shares and the
Exercise Price shall be adjusted in a fair and equitable manner, as determined
by the Board, in its sole discretion.  Notwithstanding the foregoing, any
fractional share resulting from an adjustment pursuant to this Section 9 shall
be rounded up or down to the nearest whole number, as determined by the Board,
and in no event may the Exercise Price be decreased to an amount less than the
par value, if any, of the stock subject to the Option.  The adjustments
determined by the Board pursuant to this Section 9 shall be final, binding and
conclusive.

     10.  RIGHTS AS A STOCKHOLDER, EMPLOYEE OR CONSULTANT.  The Optionee shall
          -----------------------------------------------                     
have no rights as a stockholder with respect to any shares covered by the Option
until the date of the issuance of a certificate for the shares for which the
Option has been exercised (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company).  No
adjustment shall be made for dividends, distributions or other rights for which
the record date is prior to the date such certificate is issued, except as
provided in Section 9.  Nothing in this Option Agreement shall confer upon the
Optionee any right to continue in the Service of a Participating Company or
interfere in any way with any right of the Participating Company Group to
terminate the Optionee's Service as an Employee or Consultant, as the case may
be, at any time.

     11.  NOTICE OF SALES UPON DISQUALIFYING DISPOSITION.  The Optionee shall
          ----------------------------------------------                     
dispose of the shares acquired pursuant to the Option only in accordance with
the provisions of this Option Agreement.  In addition, the Optionee shall
promptly notify the Chief Financial Officer of the Company if the Optionee
disposes of any of the shares acquired pursuant to the Option within one (1)
year after the date the Optionee exercises all or part of the Option or within
two (2) years after the Date of Option Grant and shall provide the Company with
a description of the terms and circumstances of such disposition.  Until such
time as the Optionee disposes of such shares in a manner consistent with the
provisions of this Option Agreement, unless otherwise expressly authorized by
the Company, the Optionee shall hold all shares acquired pursuant to the Option
in 

                                       37
<PAGE>
 
the Optionee's name (and not in the name of any nominee) for the one-year period
immediately after the exercise of the Option and the two-year period immediately
after Date of Option Grant. At any time during the one-year or two-year periods
set forth above, the Company may place a legend on any certificate representing
shares acquired pursuant to the Option requesting the transfer agent for the
Company's stock to notify the Company of any such transfers. The obligation of
the Optionee to notify the Company of any such transfer shall continue
notwithstanding that a legend has been placed on the certificate pursuant to the
preceding sentence.

     12.  LEGENDS.  The Company may at any time place legends referencing any
          -------                                                            
applicable federal, state or foreign securities law restrictions on all
certificates representing shares of stock subject to the provisions of this
Option Agreement.  The Optionee shall, at the request of the Company, promptly
present to the Company any and all certificates representing shares acquired
pursuant to the Option in the possession of the Optionee in order to carry out
the provisions of this Section.

     13.  RESTRICTIONS ON TRANSFER OF SHARES.  No shares acquired upon exercise
          ----------------------------------                                   
of the Option may be sold, exchanged, transferred (including, without
limitation, any transfer to a nominee or agent of the Optionee), assigned,
pledged, hypothecated or otherwise disposed of, including by operation of law,
in any manner which violates any of the provisions of this Option Agreement, and
any such attempted disposition shall be void.  The Company shall not be required
(a) to transfer on its books any shares which will have been transferred in
violation of any of the provisions set forth in this Option Agreement or (b) to
treat as owner of such shares or to accord the right to vote as such owner or to
pay dividends to any transferee to whom such shares will have been so
transferred.

     14.  BINDING EFFECT.  Subject to the restrictions on transfer set forth
          --------------                                                    
herein, this Option Agreement shall inure to the benefit of and be binding upon
the parties hereto and their respective heirs, executors, administrators,
successors and assigns.

     15.  TERMINATION OR AMENDMENT.  The Board may terminate or amend the Plan
          ------------------------                                            
or the Option at any time; provided, however, that except as provided in Section
8.2 in connection with a Transfer of Control, no such termination or amendment
may adversely affect the Option or any unexercised portion hereof without the
consent of the Optionee unless such termination or amendment is necessary to
comply with any applicable law or government regulation or is required to enable
the Option to qualify as an Incentive Stock Option.  No amendment or addition to
this Option Agreement shall be effective unless in writing.

     16.  INTEGRATED AGREEMENT.  This Option Agreement constitutes the entire
          --------------------                                               
understanding and agreement of the Optionee and the Participating Company Group
with respect to the subject matter contained herein, and there are no
agreements, understandings, restrictions, representations, or warranties among
the Optionee and the Participating Company Group with respect to such subject
matter other than those as set forth or provided for herein.  To the extent

                                       38
<PAGE>
 
contemplated herein, the provisions of this Option Agreement shall survive any
exercise of the Option and shall remain in full force and effect.

     17.  APPLICABLE LAW.  This Option Agreement shall be governed by the laws
          --------------                                                      
of the State of California as such laws are applied to agreements between
California residents entered into and to be performed entirely within the State
of California.

     2.   TAX CONSEQUENCES.
          ---------------- 

          2.1  TAX STATUS OF OPTION.  This Option is intended to be a
nonstatutory stock option and shall not be treated as an incentive stock option
within the meaning of Section 422(b) of the Code.

          2.2  ELECTION UNDER SECTION 83(b) OF THE CODE. If the Optionee
exercises this Option to purchase shares of Stock that are both nontransferable
and subject to a substantial risk of forfeiture, the Optionee understands that
the Optionee should consult with the Optionee's tax advisor regarding the
advisability of filing with the Internal Revenue Service an election under
Section 83(b) of the Code, which must be filed no later than thirty (30) days
after the date on which the Optionee exercises the Option. Shares acquired upon
exercise of the Option are nontransferable and subject to a substantial risk of
forfeiture if, for example, (a) they are unvested and are subject to a right of
the Company to repurchase such shares at the Optionee's original purchase price
if the Optionee's Service terminates, or (b) the Optionee is subject to a
restriction on transfer to comply with "Pooling-of-Interests Accounting" rules.
Failure to file an election under Section 83(b), if appropriate, may result in
adverse tax consequences to the

                                       43
<PAGE>
 
Optionee. The Optionee acknowledges that the Optionee has been advised to
consult with a tax advisor prior to the exercise of the Option regarding the tax
consequences to the Optionee of the exercise of the Option. AN ELECTION UNDER
SECTION 83(b) MUST BE FILED WITHIN 30 DAYS AFTER THE DATE ON WHICH THE OPTIONEE
PURCHASES SHARES. THIS TIME PERIOD CANNOT BE EXTENDED. THE OPTIONEE ACKNOWLEDGES
THAT TIMELY FILING OF A SECTION 83(b) ELECTION IS THE OPTIONEE'S SOLE
RESPONSIBILITY, EVEN IF THE OPTIONEE REQUESTS THE COMPANY OR ITS REPRESENTATIVE
TO FILE SUCH ELECTION ON HIS OR HER BEHALF.

     3.   ADMINISTRATION.  All questions of interpretation concerning this
          --------------                                                  
Option Agreement shall be determined by the Board, including any duly appointed
Committee of the Board.  All determinations by the Board shall be final and
binding upon all persons having an interest in the Option.  Any officer of a
Participating Company shall have the authority to act on behalf of the Company
with respect to any matter, right, obligation, or election which is the
responsibility of or which is allocated to the Company herein, provided the
officer has apparent authority with respect to such matter, right, obligation,
or election.

     4.   EXERCISE OF THE OPTION.
          ---------------------- 

          4.1  RIGHT TO EXERCISE.  Except as otherwise provided herein, the
Option shall be exercisable on and after the Initial Exercise Date and prior to
the termination of the Option (as provided in Section 6) in an amount not to
exceed the Number of Option Shares multiplied by the Vested Ratio less the
number of shares previously acquired upon exercise of the Option. In no event
shall the Option be exercisable for more shares than the Number of Option
Shares.

          4.2  METHOD OF EXERCISE.  Exercise of the Option shall be by written
notice to the Company which must state the election to exercise the Option, the
number of whole shares of Stock for which the Option is being exercised and such
other representations and agreements as to the Optionee's investment intent with
respect to such shares as may be required pursuant to the provisions of this
Option Agreement. The written notice must be signed by the Optionee and must be
delivered in person, by certified or registered mail, return receipt requested,
by confirmed facsimile transmission, or by such other means as the Company may
permit, to the Chief Financial Officer of the Company, or other authorized
representative of the Participating Company Group, prior to the termination of
the Option as set forth in Section 6, accompanied by full payment of the
aggregate Exercise Price for the number of shares of Stock being purchased. The
Option shall be deemed to be exercised upon receipt by the Company of such
written notice and the aggregate Exercise Price.

          4.3  PAYMENT OF EXERCISE PRICE.

               (a)  FORMS OF CONSIDERATION AUTHORIZED. Except as otherwise
provided below, payment of the aggregate Exercise Price for the number of shares
of Stock for which the Option is being exercised shall be made (i) in cash, by
check, or cash equivalent, (ii) by tender to the Company of whole shares of
Stock owned by the Optionee having a Fair Market Value (as determined by the
Company without regard to any restrictions on transferability applicable to such
stock by reason of federal or state securities laws or agreements with an
underwriter for the Company) not less than the aggregate Exercise Price, (iii)
by means of a Cashless Exercise, as defined in Section 4.3(c), or (iv) by any
combination of the foregoing.

               (b)  TENDER OF STOCK.  Notwithstanding the foregoing, the Option
may not be exercised by tender to the Company of shares of Stock to the extent
such tender of Stock would constitute a violation of the provisions of any law,
regulation or agreement restricting the redemption of the Company's stock. The
Option may not be exercised by tender to the Company of shares of Stock unless
such shares either have been owned by the Optionee for more than six (6) months
or were not acquired, directly or indirectly, from the Company.

               (c)  CASHLESS EXERCISE.  A "CASHLESS EXERCISE" means the
assignment in a form acceptable to the Company of the proceeds of a sale or loan
with respect to some or all of the shares of Stock acquired upon the exercise of
the Option pursuant to a program or procedure approved by the Company
(including, without limitation, through an exercise complying with the
provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System). The Company reserves, at any and all
times, the right, in the Company's sole and absolute discretion, to decline to
approve or terminate any such program or procedure.

          4.4  TAX WITHHOLDING.  At the time the Option is exercised, in whole
or in part, or at any time thereafter as requested by the Company, the Optionee
hereby authorizes withholding from payroll and any other amounts payable to the
Optionee, and otherwise agrees to make adequate provision for (including by
means of a Cashless Exercise to the extent permitted by the Company), any sums
required to satisfy the federal, state, local and foreign tax withholding
obligations of the Participating Company Group, if any, which arise in
connection with the Option, including, without limitation, obligations arising
upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in
whole or in part, of any shares acquired upon exercise of the Option, (iii) the
operation of any law or regulation providing for the imputation of interest, or
(iv) the lapsing of any restriction with respect to any shares acquired upon
exercise of the Option. The Optionee is cautioned that the Option is not
exercisable unless the tax withholding obligations of the Participating Company
Group are satisfied. Accordingly, the Optionee may not be able to exercise the
Option when desired even though the Option is vested, and the Company shall have
no obligation to issue a certificate for such shares or release such shares from
any escrow provided for herein.

          4.5  CERTIFICATE REGISTRATION.  Except in the event the Exercise Price
is paid by means of a Cashless Exercise, the certificate for the shares as to
which the Option is exercised

                                       45
<PAGE>
 
shall be registered in the name of the Optionee, or, if applicable, in the names
of the heirs of the Optionee.

          4.6  RESTRICTIONS ON GRANT OF THE OPTION AND ISSUANCE OF SHARES. The
grant of the Option and the issuance of shares of Stock upon exercise of the
Option shall be subject to compliance with all applicable requirements of
federal, state or foreign law with respect to such securities. The Option may
not be exercised if the issuance of shares of Stock upon exercise would
constitute a violation of any applicable federal, state or foreign securities
laws or other law or regulations or the requirements of any stock exchange or
market system upon which the Stock may then be listed. In addition, the Option
may not be exercised unless (i) a registration statement under the Securities
Act shall at the time of exercise of the Option be in effect with respect to the
shares issuable upon exercise of the Option or (ii) in the opinion of legal
counsel to the Company, the shares issuable upon exercise of the Option may be
issued in accordance with the terms of an applicable exemption from the
registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT
THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED.
ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED
EVEN THOUGH THE OPTION IS VESTED. Questions concerning this restriction should
be directed to the Chief Financial Officer of the Company. The inability of the
Company to obtain from any regulatory body having jurisdiction the authority, if
any, deemed by the Company's legal counsel to be necessary to the lawful
issuance and sale of any shares subject to the Option shall relieve the Company
of any liability in respect of the failure to issue or sell such shares as to
which such requisite authority shall not have been obtained. As a condition to
the exercise of the Option, the Company may require the Optionee to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with
any applicable law or regulation and to make any representation or warranty with
respect thereto as may be requested by the Company.

          4.7  FRACTIONAL SHARES.  The Company shall not be required to issue
fractional shares upon the exercise of the Option.

     5.   NONTRANSFERABILITY OF THE OPTION.  The Option may be exercised during
          --------------------------------                                     
the lifetime of the Optionee only by the Optionee or the Optionee's guardian or
legal representative and may not be assigned or transferred in any manner except
by will or by the laws of descent and distribution.  Following the death of the
Optionee, the Option, to the extent provided in Section 7, may be exercised by
the Optionee's legal representative or by any person empowered to do so under
the deceased Optionee's will or under the then applicable laws of descent and
distribution.

     6.   TERMINATION OF THE OPTION.  The Option shall terminate and may no
          -------------------------                                        
longer be exercised on the first to occur of (a) the Option Expiration Date, (b)
the last date for exercising the Option following termination of the Optionee's
Service as described in Section 7, or (c) a Transfer of Control to the extent
provided in Section 8.

                                       46
<PAGE>
 
     7.   EFFECT OF TERMINATION OF SERVICE.
          -------------------------------- 

          7.1  OPTION EXERCISABILITY.

               (a)  DISABILITY.  If the Optionee's Service with the
Participating Company Group is terminated because of the Disability of the
Optionee, the Option, to the extent unexercised and exercisable on the date on
which the Optionee's Service terminated, may be exercised by the Optionee (or
the Optionee's guardian or legal representative) at any time prior to the
expiration of twelve (12) months after the date on which the Optionee's Service
terminated, but in any event no later than the Option Expiration Date.

               (b)  DEATH.  If the Optionee's Service with the Participating
Company Group is terminated because of the death of the Optionee, the Option, to
the extent unexercised and exercisable on the date on which the Optionee's
Service terminated, may be exercised by the Optionee's legal representative or
other person who acquired the right to exercise the Option by reason of the
Optionee's death at any time prior to the expiration of twelve (12) months after
the date on which the Optionee's Service terminated, but in any event no later
than the Option Expiration Date. The Optionee's Service shall be deemed to have
terminated on account of death if the Optionee dies within three (3) months
after the Optionee's termination of Service.

               (c)  OTHER TERMINATION OF SERVICE. If the Optionee's Service with
the Participating Company Group terminates for any reason, except Disability or
death, the Option, to the extent unexercised and exercisable by the Optionee on
the date on which the Optionee's Service terminated, may be exercised by the
Optionee within three (3) months (or such other longer period of time as
determined by the Board, in its sole discretion) after the date on which the
Optionee's Service terminated, but in any event no later than the Option
Expiration Date.

          7.2  EXTENSION IF EXERCISE PREVENTED BY LAW.  Notwithstanding the
foregoing, if the exercise of the Option within the applicable time periods set
forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option
shall remain exercisable until three (3) months after the date the Optionee is
notified by the Company that the Option is exercisable, but in any event no
later than the Option Expiration Date.

          7.3  EXTENSION IF OPTIONEE SUBJECT TO SECTION 16(b). Notwithstanding
the foregoing, if a sale within the applicable time periods set forth in Section
7.1 of shares acquired upon the exercise of the Option would subject the
Optionee to suit under Section 16(b) of the Exchange Act, the Option shall
remain exercisable until the earliest to occur of (i) the tenth (10th) day
following the date on which a sale of such shares by the Optionee would no
longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day
after the Optionee's termination of Service, or (iii) the Option Expiration
Date.

          7.4  LEAVE OF ABSENCE. For purposes of Section 7.1, the Optionee's
Service with the Participating Company Group shall not be deemed to terminate if
the Optionee takes any military leave, sick leave, or other bona fide leave of
absence approved by the Company of

                                       47
<PAGE>
 
ninety (90) days or less. In the event of a leave of absence in excess of ninety
(90) days, the Optionee's Service shall be deemed to terminate on the ninety-
first (91st) day of such leave unless the Optionee's right to return to Service
with the Participating Company Group remains guaranteed by statute or contract.
Notwithstanding the foregoing, unless otherwise designated by the Company (or
required by law), a leave of absence shall not be treated as Service for
purposes of determining the Optionee's Vested Ratio.

     8.   TRANSFER OF CONTROL.
          ------------------- 

          8.1  DEFINITIONS.

               (a)  An "OWNERSHIP CHANGE EVENT" shall be deemed to have occurred
if any of the following occurs with respect to the Company:

                    (i)   the direct or indirect sale or exchange in a single or
series of related transactions by the stockholders of the Company of more than
fifty percent (50%) of the voting stock of the Company;

                    (ii)  a merger or consolidation in which the Company is a
party;

                    (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or

                    (iv)  a liquidation or dissolution of the Company.

               (b)  A "TRANSFER OF CONTROL" shall mean an Ownership Change Event
or a series of related Ownership Change Events (collectively, the "TRANSACTION")
wherein the stockholders of the Company immediately before the Transaction do
not retain immediately after the Transaction, in substantially the same
proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "TRANSFEREE
CORPORATION(S)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

          8.2  EFFECT OF TRANSFER OF CONTROL ON OPTION. In the event of a
Transfer of Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "ACQUIRING
CORPORATION"), may either assume the Company's rights and obligations under the
Option or substitute for the Option a substantially equivalent

                                       48
<PAGE>
 
option for the Acquiring Corporation's stock. For purposes of this Section 8.2,
an Option shall be deemed assumed if, following the Transfer of Control, the
Option confers the right to purchase, for each share of Stock subject to the
Option immediately prior to the Transfer of Control, the consideration (whether
stock, cash or other securities or property) to which a holder of a share of
Stock on the effective date of the Transfer of Control was entitled. In the
event the Acquiring Corporation elects not to assume the Company's rights and
obligations under the Option or substitute for the Option in connection with the
Transfer of Control, any unexercised portion of the Option shall be immediately
exercisable and vested in full as of the date ten (10) days prior to the date of
the Transfer of Control. Any exercise of the Option that was permissible solely
by reason of this Section 8.2 shall be conditioned upon the consummation of the
Transfer of Control. The Option shall terminate and cease to be outstanding
effective as of the date of the Transfer of Control to the extent that the
Option is neither assumed or substituted for by the Acquiring Corporation in
connection with the Transfer of Control nor exercised as of the date of the
Transfer of Control. Notwithstanding the foregoing, shares acquired upon
exercise of the Option prior to the Transfer of Control and any consideration
received pursuant to the Transfer of Control with respect to such shares shall
continue to be subject to all applicable provisions of this Option Agreement
except as otherwise provided herein. Furthermore, notwithstanding the foregoing,
if the corporation the stock of which is subject to the Option immediately prior
to an Ownership Change Event described in Section 8.1(a)(i) constituting a
Transfer of Control is the surviving or continuing corporation and immediately
after such Ownership Change Event less than fifty percent (50%) of the total
combined voting power of its voting stock is held by another corporation or by
other corporations that are members of an affiliated group within the meaning of
Section 1504(a) of the Code without regard to the provisions of Section 1504(b)
of the Code, the Option shall not terminate unless the Board otherwise provides
in its sole discretion.

     9.   ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.  In the event of any
          --------------------------------------------                      
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification, or similar change in the capital structure of the Company,
appropriate adjustments shall be made in the number, Exercise Price and class of
shares of stock subject to the Option.  If a majority of the shares which are of
the same class as the shares that are subject to the Option are exchanged for,
converted into, or otherwise become (whether or not pursuant to an Ownership
Change Event) shares of another corporation (the "NEW SHARES"), the Board may
unilaterally amend the Option to provide that the Option is exercisable for New
Shares.  In the event of any such amendment, the Number of Option Shares and the
Exercise Price shall be adjusted in a fair and equitable manner, as determined
by the Board, in its sole discretion.  Notwithstanding the foregoing, any
fractional share resulting from an adjustment pursuant to this Section 9 shall
be rounded up or down to the nearest whole number, as determined by the Board,
and in no event may the Exercise Price be decreased to an amount less than the
par value, if any, of the stock subject to the Option.  The adjustments
determined by the Board pursuant to this Section 9 shall be final, binding and
conclusive.

     10.  RIGHTS AS A STOCKHOLDER, EMPLOYEE OR CONSULTANT.  The Optionee shall
          -----------------------------------------------                     
have no rights as a stockholder with respect to any shares covered by the Option
until the date of the issuance of a certificate for the shares for which the
Option has been exercised (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the 

                                       49
<PAGE>
 
Company). No adjustment shall be made for dividends, distributions or other
rights for which the record date is prior to the date such certificate is
issued, except as provided in Section 9. Nothing in this Option Agreement shall
confer upon the Optionee any right to continue in the Service of a Participating
Company or interfere in any way with any right of the Participating Company
Group to terminate the Optionee's Service as an Employee or Consultant, as the
case may be, at any time.

     11.  LEGENDS.  The Company may at any time place legends referencing any
          -------                                                            
applicable federal, state or foreign securities law restrictions on all
certificates representing shares of stock subject to the provisions of this
Option Agreement.  The Optionee shall, at the request of the Company, promptly
present to the Company any and all certificates representing shares acquired
pursuant to the Option in the possession of the Optionee in order to carry out
the provisions of this Section.

     12.  RESTRICTIONS ON TRANSFER OF SHARES.  No shares acquired upon exercise
          ----------------------------------                                   
of the Option may be sold, exchanged, transferred (including, without
limitation, any transfer to a nominee or agent of the Optionee), assigned,
pledged, hypothecated or otherwise disposed of, including by operation of law,
in any manner which violates any of the provisions of this Option Agreement, and
any such attempted disposition shall be void.  The Company shall not be required
(a) to transfer on its books any shares which will have been transferred in
violation of any of the provisions set forth in this Option Agreement or (b) to
treat as owner of such shares or to accord the right to vote as such owner or to
pay dividends to any transferee to whom such shares will have been so
transferred.

     13.  BINDING EFFECT.  Subject to the restrictions on transfer set forth
          --------------                                                    
herein, this Option Agreement shall inure to the benefit of and be binding upon
the parties hereto and their respective heirs, executors, administrators,
successors and assigns.

     14.  TERMINATION OR AMENDMENT.  The Board may terminate or amend the Plan
          ------------------------                                            
or the Option at any time; provided, however, that except as provided in Section
8.2 in connection with a Transfer of Control, no such termination or amendment
may adversely affect the Option or any unexercised portion hereof without the
consent of the Optionee unless such termination or amendment is necessary to
comply with any applicable law or government regulation.  No amendment or
addition to this Option Agreement shall be effective unless in writing.

     15.  INTEGRATED AGREEMENT.  This Option Agreement constitutes the entire
          --------------------                                               
understanding and agreement of the Optionee and the Participating Company Group
with respect to the subject matter contained herein, and there are no
agreements, understandings, restrictions, representations, or warranties among
the Optionee and the Participating Company Group with respect to such subject
matter other than those as set forth or provided for herein, except for the
provisions set forth in a change of control agreement between the Company and
the Optionee, if any.  To the extent contemplated herein, the provisions of this
Option Agreement shall survive any exercise of the Option and shall remain in
full force and effect.

     16.  APPLICABLE LAW.  This Option Agreement shall be governed by the laws
          --------------                                                      
of the State of California as such laws are applied to agreements between

     2.   TAX CONSEQUENCES.
          ---------------- 

          2.1  TAX STATUS OF OPTION. This Option is intended to be a
nonstatutory stock option and shall not be treated as an incentive stock option
within the meaning of Section 422(b) of the Code.

          2.2  ELECTION UNDER SECTION 83(B) OF THE CODE. If the Optionee
exercises this Option to purchase shares of Stock that are both nontransferable
and subject to a substantial risk of forfeiture, the Optionee understands that
the Optionee should consult with the Optionee's tax advisor regarding the
advisability of filing with the Internal Revenue Service an election under
Section 83(b) of the Code, which must be filed no later than thirty (30) days
after the date on which the Optionee exercises the Option. Shares acquired upon
exercise of the Option are nontransferable and subject to a substantial risk of
forfeiture if, for example, (a) they are unvested and are subject to a right of
the Company to repurchase such shares at the Optionee's original purchase price
if the Optionee's Service terminates, or (b) the Optionee is subject to a
restriction on transfer to comply with "Pooling-of-Interests Accounting" rules.
Failure to file an election under Section 83(b), if appropriate, may result in
adverse tax consequences to the 

                                       55
<PAGE>
 
Optionee. The Optionee acknowledges that the Optionee has been advised to
consult with a tax advisor prior to the exercise of the Option regarding the tax
consequences to the Optionee of the exercise of the Option. AN ELECTION UNDER
SECTION 83(b) MUST BE FILED WITHIN 30 DAYS AFTER THE DATE ON WHICH THE OPTIONEE
PURCHASES SHARES. THIS TIME PERIOD CANNOT BE EXTENDED. THE OPTIONEE ACKNOWLEDGES
THAT TIMELY FILING OF A SECTION 83(b) ELECTION IS THE OPTIONEE'S SOLE
RESPONSIBILITY, EVEN IF THE OPTIONEE REQUESTS THE COMPANY OR ITS REPRESENTATIVE
TO FILE SUCH ELECTION ON HIS OR HER BEHALF.

     3.   ADMINISTRATION.  All questions of interpretation concerning this
          --------------                                                  
Option Agreement shall be determined by the Board, including any duly appointed
Committee of the Board.  All determinations by the Board shall be final and
binding upon all persons having an interest in the Option.  Any officer of a
Participating Company shall have the authority to act on behalf of the Company
with respect to any matter, right, obligation, or election which is the
responsibility of or which is allocated to the Company herein, provided the
officer has apparent authority with respect to such matter, right, obligation,
or election.

     4.   EXERCISE OF THE OPTION.
          ---------------------- 

          4.1  RIGHT TO EXERCISE. Except as otherwise provided herein, the
Option shall be exercisable on and after the Initial Exercise Date and prior to
the termination of the Option (as provided in Section 6) in an amount not to
exceed the Number of Option Shares multiplied by the Vested Ratio less the
number of shares previously acquired upon exercise of the Option. In no event
shall the Option be exercisable for more shares than the Number of Option
Shares.

          4.2  METHOD OF EXERCISE. Exercise of the Option shall be by written
notice to the Company which must state the election to exercise the Option, the
number of whole shares of Stock for which the Option is being exercised and such
other representations and agreements as to the Optionee's investment intent with
respect to such shares as may be required pursuant to the provisions of this
Option Agreement. The written notice must be signed by the Optionee and must be
delivered in person, by certified or registered mail, return receipt requested,
by confirmed facsimile transmission, or by such other means as the Company may
permit, to the Chief Financial Officer of the Company, or other authorized
representative of the Participating Company Group, prior to the termination of
the Option as set forth in Section 6, accompanied by full payment of the
aggregate Exercise Price for the number of shares of Stock being purchased. The
Option shall be deemed to be exercised upon receipt by the Company of such
written notice and the aggregate Exercise Price.

                                       56
<PAGE>
 
          4.3  PAYMENT OF EXERCISE PRICE.

               (a)  FORMS OF CONSIDERATION AUTHORIZED. Except as otherwise
provided below, payment of the aggregate Exercise Price for the number of shares
of Stock for which the Option is being exercised shall be made (i) in cash, by
check, or cash equivalent, (ii) by tender to the Company of whole shares of
Stock owned by the Optionee having a Fair Market Value (as determined by the
Company without regard to any restrictions on transferability applicable to such
stock by reason of federal or state securities laws or agreements with an
underwriter for the Company) not less than the aggregate Exercise Price, (iii)
by means of a Cashless Exercise, as defined in Section 4.3(c), or (iv) by any
combination of the foregoing.

               (b)  TENDER OF STOCK. Notwithstanding the foregoing, the Option
may not be exercised by tender to the Company of shares of Stock to the extent
such tender of Stock would constitute a violation of the provisions of any law,
regulation or agreement restricting the redemption of the Company's stock. The
Option may not be exercised by tender to the Company of shares of Stock unless
such shares either have been owned by the Optionee for more than six (6) months
or were not acquired, directly or indirectly, from the Company.

               (c)  CASHLESS EXERCISE.  A "CASHLESS EXERCISE" means the
assignment in a form acceptable to the Company of the proceeds of a sale or loan
with respect to some or all of the shares of Stock acquired upon the exercise of
the Option pursuant to a program or procedure approved by the Company
(including, without limitation, through an exercise complying with the
provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System). The Company reserves, at any and all
times, the right, in the Company's sole and absolute discretion, to decline to
approve or terminate any such program or procedure.

          4.4  TAX WITHHOLDING. At the time the Option is exercised, in whole or
in part, or at any time thereafter as requested by the Company, the Optionee
hereby authorizes withholding from payroll and any other amounts payable to the
Optionee, and otherwise agrees to make adequate provision for (including by
means of a Cashless Exercise to the extent permitted by the Company), any sums
required to satisfy the federal, state, local and foreign tax withholding
obligations of the Participating Company Group, if any, which arise in
connection with the Option, including, without limitation, obligations arising
upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in
whole or in part, of any shares acquired upon exercise of the Option, (iii) the
operation of any law or regulation providing for the imputation of interest, or
(iv) the lapsing of any restriction with respect to any shares acquired upon
exercise of the Option. The Optionee is cautioned that the Option is not
exercisable unless the tax withholding obligations of the Participating Company
Group are satisfied. Accordingly, the Optionee may not be able to exercise the
Option when desired even though the Option is vested, and the Company shall have
no obligation to issue a certificate for such shares or release such shares from
any escrow provided for herein.

          4.5  CERTIFICATE REGISTRATION. Except in the event the Exercise Price
is paid by means of a Cashless Exercise, the certificate for the shares as to
which the Option is exercised

                                       57
<PAGE>
 
shall be registered in the name of the Optionee, or, if applicable, in the names
of the heirs of the Optionee.

          4.6  RESTRICTIONS ON GRANT OF THE OPTION AND ISSUANCE OF SHARES. The
grant of the Option and the issuance of shares of Stock upon exercise of the
Option shall be subject to compliance with all applicable requirements of
federal, state or foreign law with respect to such securities. The Option may
not be exercised if the issuance of shares of Stock upon exercise would
constitute a violation of any applicable federal, state or foreign securities
laws or other law or regulations or the requirements of any stock exchange or
market system upon which the Stock may then be listed. In addition, the Option
may not be exercised unless (i) a registration statement under the Securities
Act shall at the time of exercise of the Option be in effect with respect to the
shares issuable upon exercise of the Option or (ii) in the opinion of legal
counsel to the Company, the shares issuable upon exercise of the Option may be
issued in accordance with the terms of an applicable exemption from the
registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT
THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED.
ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED
EVEN THOUGH THE OPTION IS VESTED. Questions concerning this restriction should
be directed to the Chief Financial Officer of the Company. The inability of the
Company to obtain from any regulatory body having jurisdiction the authority, if
any, deemed by the Company's legal counsel to be necessary to the lawful
issuance and sale of any shares subject to the Option shall relieve the Company
of any liability in respect of the failure to issue or sell such shares as to
which such requisite authority shall not have been obtained. As a condition to
the exercise of the Option, the Company may require the Optionee to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with
any applicable law or regulation and to make any representation or warranty with
respect thereto as may be requested by the Company.

          4.7  FRACTIONAL SHARES.  The Company shall not be required to issue
fractional shares upon the exercise of the Option.

     5.   NONTRANSFERABILITY OF THE OPTION.  The Option may be exercised during
          --------------------------------                                     
the lifetime of the Optionee only by the Optionee or the Optionee's guardian or
legal representative and may not be assigned or transferred in any manner except
by will or by the laws of descent and distribution.  Following the death of the
Optionee, the Option, to the extent provided in Section 7, may be exercised by
the Optionee's legal representative or by any person empowered to do so under
the deceased Optionee's will or under the then applicable laws of descent and
distribution.

     6.   TERMINATION OF THE OPTION.  The Option shall terminate and may no
          -------------------------                                        
longer be exercised on the first to occur of (a) the Option Expiration Date, (b)
the last date for exercising the Option following termination of the Optionee's
Service as described in Section 7, or (c) a Transfer of Control to the extent
provided in Section 8.

                                       58
<PAGE>
 
     7.   EFFECT OF TERMINATION OF SERVICE.
          -------------------------------- 

          7.1  OPTION EXERCISABILITY.

               (a)  DISABILITY. If the Optionee's Service with the Participating
Company Group is terminated because of the Disability of the Optionee, the
Option, to the extent unexercised and exercisable on the date on which the
Optionee's Service terminated, may be exercised by the Optionee (or the
Optionee's guardian or legal representative) at any time prior to the expiration
of twelve (12) months after the date on which the Optionee's Service terminated,
but in any event no later than the Option Expiration Date.

               (b)  DEATH. If the Optionee's Service with the Participating
Company Group is terminated because of the death of the Optionee, the Option, to
the extent unexercised and exercisable on the date on which the Optionee's
Service terminated, may be exercised by the Optionee's legal representative or
other person who acquired the right to exercise the Option by reason of the
Optionee's death at any time prior to the expiration of twelve (12) months after
the date on which the Optionee's Service terminated, but in any event no later
than the Option Expiration Date. The Optionee's Service shall be deemed to have
terminated on account of death if the Optionee dies within three (3) months
after the Optionee's termination of Service.

               (c)  OTHER TERMINATION OF SERVICE. If the Optionee's Service with
the Participating Company Group terminates for any reason, except Disability or
death, the Option, to the extent unexercised and exercisable by the Optionee on
the date on which the Optionee's Service terminated, may be exercised by the
Optionee within three (3) months (or such other longer period of time as
determined by the Board, in its sole discretion) after the date on which the
Optionee's Service terminated, but in any event no later than the Option
Expiration Date.

          7.2  EXTENSION IF EXERCISE PREVENTED BY LAW.  Notwithstanding the
foregoing, if the exercise of the Option within the applicable time periods set
forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option
shall remain exercisable until three (3) months after the date the Optionee is
notified by the Company that the Option is exercisable, but in any event no
later than the Option Expiration Date.

          7.3  EXTENSION IF OPTIONEE SUBJECT TO SECTION 16(B). Notwithstanding
the foregoing, if a sale within the applicable time periods set forth in Section
7.1 of shares acquired upon the exercise of the Option would subject the
Optionee to suit under Section 16(b) of the Exchange Act, the Option shall
remain exercisable until the earliest to occur of (i) the tenth (10th) day
following the date on which a sale of such shares by the Optionee would no
longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day
after the Optionee's termination of Service, or (iii) the Option Expiration
Date.

          7.4  LEAVE OF ABSENCE. For purposes of Section 7.1, the Optionee's
Service with the Participating Company Group shall not be deemed to terminate if
the Optionee takes any military leave, sick leave, or other bona fide leave of
absence approved by the Company of

                                       59
<PAGE>
 
ninety (90) days or less. In the event of a leave of absence in excess of ninety
(90) days, the Optionee's Service shall be deemed to terminate on the ninety-
first (91st) day of such leave unless the Optionee's right to return to Service
with the Participating Company Group remains guaranteed by statute or contract.
Notwithstanding the foregoing, unless otherwise designated by the Company (or
required by law), a leave of absence shall not be treated as Service for
purposes of determining the Optionee's Vested Ratio.

     8.   TRANSFER OF CONTROL.
          ------------------- 

          8.1  DEFINITIONS.

               (a)  An "OWNERSHIP CHANGE EVENT" shall be deemed to have occurred
if any of the following occurs with respect to the Company:

                    (i)   the direct or indirect sale or exchange in a single or
series of related transactions by the stockholders of the Company of more than
fifty percent (50%) of the voting stock of the Company;

                    (ii)  a merger or consolidation in which the Company is a
party;

                    (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or

                    (iv)  a liquidation or dissolution of the Company.

               (b)  A "TRANSFER OF CONTROL" shall mean an Ownership Change Event
or a series of related Ownership Change Events (collectively, the "TRANSACTION")
wherein the stockholders of the Company immediately before the Transaction do
not retain immediately after the Transaction, in substantially the same
proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "TRANSFEREE
CORPORATION(S)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

          8.2  EFFECT OF TRANSFER OF CONTROL ON OPTION. In the event of a
Transfer of Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "ACQUIRING
CORPORATION"), may either assume the Company's rights and obligations under the
Option or substitute for the Option a substantially equivalent

                                       60
<PAGE>
 
option for the Acquiring Corporation's stock. For purposes of this Section 8.2,
an Option shall be deemed assumed if, following the Transfer of Control, the
Option confers the right to purchase, for each share of Stock subject to the
Option immediately prior to the Transfer of Control, the consideration (whether
stock, cash or other securities or property) to which a holder of a share of
Stock on the effective date of the Transfer of Control was entitled. In the
event the Acquiring Corporation elects not to assume the Company's rights and
obligations under the Option or substitute for the Option in connection with the
Transfer of Control, any unexercised portion of the Option shall be immediately
exercisable and vested in full as of the date ten (10) days prior to the date of
the Transfer of Control. Any exercise of the Option that was permissible solely
by reason of this Section 8.2 shall be conditioned upon the consummation of the
Transfer of Control. The Option shall terminate and cease to be outstanding
effective as of the date of the Transfer of Control to the extent that the
Option is neither assumed or substituted for by the Acquiring Corporation in
connection with the Transfer of Control nor exercised as of the date of the
Transfer of Control. Notwithstanding the foregoing, shares acquired upon
exercise of the Option prior to the Transfer of Control and any consideration
received pursuant to the Transfer of Control with respect to such shares shall
continue to be subject to all applicable provisions of this Option Agreement
except as otherwise provided herein. Furthermore, notwithstanding the foregoing,
if the corporation the stock of which is subject to the Option immediately prior
to an Ownership Change Event described in Section 8.1(a)(i) constituting a
Transfer of Control is the surviving or continuing corporation and immediately
after such Ownership Change Event less than fifty percent (50%) of the total
combined voting power of its voting stock is held by another corporation or by
other corporations that are members of an affiliated group within the meaning of
Section 1504(a) of the Code without regard to the provisions of Section 1504(b)
of the Code, the Option shall not terminate unless the Board otherwise provides
in its sole discretion.

     9.   ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.  In the event of any
          --------------------------------------------                      
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification, or similar change in the capital structure of the Company,
appropriate adjustments shall be made in the number, Exercise Price and class of
shares of stock subject to the Option.  If a majority of the shares which are of
the same class as the shares that are subject to the Option are exchanged for,
converted into, or otherwise become (whether or not pursuant to an Ownership
Change Event) shares of another corporation (the "NEW SHARES"), the Board may
unilaterally amend the Option to provide that the Option is exercisable for New
Shares.  In the event of any such amendment, the Number of Option Shares and the
Exercise Price shall be adjusted in a fair and equitable manner, as determined
by the Board, in its sole discretion.  Notwithstanding the foregoing, any
fractional share resulting from an adjustment pursuant to this Section 9 shall
be rounded up or down to the nearest whole number, as determined by the Board,
and in no event may the Exercise Price be decreased to an amount less than the
par value, if any, of the stock subject to the Option.  The adjustments
determined by the Board pursuant to this Section 9 shall be final, binding and
conclusive.

     10.  RIGHTS AS A STOCKHOLDER, EMPLOYEE OR CONSULTANT.  The Optionee shall
          -----------------------------------------------                     
have no rights as a stockholder with respect to any shares covered by the Option
until the date of the issuance of a certificate for the shares for which the
Option has been exercised (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the 

                                       61
<PAGE>
 
Company). No adjustment shall be made for dividends, distributions or other
rights for which the record date is prior to the date such certificate is
