                              EMPLOYMENT AGREEMENT

         THIS EMPLOYMENT AGREEMENT is entered into as of October 11, 1999, (the
"Effective Date") by and between JEFFREY R. RODEK (the "Employee") and HYPERION
SOLUTIONS CORPORATION, a Delaware corporation (the "Company").

                  1.       DUTIES AND SCOPE OF EMPLOYMENT.

                           (a)  POSITION. For the term of his employment under
this Agreement ("Employment"), the Company agrees to employ the Employee in the
position of Chief Executive Officer, reporting to the Board of Directors. In
addition, the Company agrees to elect the Employee as Chairman of the Board of
Directors promptly following his acceptance of the terms of this Agreement. It
is expected that the Employee's primary office will be in Sunnyvale, California,
at the Company's headquarters.

                           (b)  OBLIGATIONS TO THE COMPANY. During the term of
his Employment, the Employee shall devote his full business efforts and time to
the Company. During the term of his Employment, without the prior written
approval of the Company (which shall not be unreasonably withheld), the Employee
shall not render services in any capacity to any other person or entity and
shall not act as a sole proprietor, partner or managing member of any other
person or entity or as a shareholder owning more than one percent of the stock
of any other corporation. The foregoing, however, shall not preclude the
Employee from engaging in reasonable community, school or charitable activities.
The Employee shall comply with the Company's policies and rules, as they may be
in effect from time to time during the term of his Employment.

                           (c)  NO CONFLICTING OBLIGATIONS. The Employee
represents and warrants to the Company that he is under no obligations or
commitments, whether contractual or otherwise, that are inconsistent with his
obligations under this Agreement. The Employee represents and warrants that he
will not use or disclose, in connection with his employment by the Company, any
trade secrets or other proprietary information or intellectual property in which
he or any other person has any right, title or interest and that his employment
by the Company as contemplated by this Agreement will not infringe or violate
the rights of any other person. The Employee represents and warrants to the
Company that he has returned all property and confidential information belonging
to any prior employer.

                  2.       COMPENSATION.

                           (a)  SALARY. The Company shall pay the Employee as
compensation for his services a base salary at a gross annual rate of not less
than $400,000. Such salary shall be payable in accordance with the Company's
standard payroll procedures. (The annual compensation specified in this
Subsection (a), together with any increases in such compensation that the
Company may grant from time to time, is referred to in this Agreement as "Base
Compensation.").

                           (b)  INCENTIVE BONUSES. Commencing with the Company's
fiscal year ending June 30, 2002, the Employee shall be eligible to be
considered for an annual incentive

bonus with a target amount equal to 50% of the Employee's Base Compensation with
the potential for a greater amount at the discretion of the Company's Board of
Directors (the "Board") or its Compensation Committee in the event of
exceptional performance. Such bonus (if any) shall be awarded based on objective
or subjective criteria established in advance by the Board or its Compensation
Committee. The determinations of the Board or such Committee with respect to
such bonus shall be final and binding.

                           (c)  RESTRICTED STOCK. The Company hereby grants the
Employee 100,000 shares of the Company's Common Stock, subject to certain
restrictions (the "Restricted Stock"), at a purchase price equal to its par
value of $0.001 per share, subject to the following additional terms:

                                (i)  The aggregate purchase price has been paid
         by, or on behalf of, the Employee.

                                (ii)  The Restricted Stock is subject to the
         terms of an agreement (the "Restricted Stock Agreement") that shall be
         presented to the Employee by the officers of the Company within ten
         (10) days of the Effective Date containing terms substantially similar
         to those of this Agreement and, where applicable, of the Company's 1995
         Stock Option/Stock Issuance Plan as amended and restated as of August
         21, 1998 (the "Option/Issuance Plan"), a copy of which has been
         provided to the Employee.

                                (iii) The Employee's interest will become fully
         vested and all restrictions will lapse on 6,250 shares on the day
         corresponding to the Effective Date of each successive third month
         following the Effective Date, so that the Employee's interest will
         become fully vested in all of the shares of Restricted Stock on the
         anniversary of the Effective Date in 2003.

                                (iv)  As of the Effective Date, the Employee has
         full stockholder rights with respect to the shares of Restricted Stock
         including the right to vote the shares and to receive dividends,
         whether or not his interest in such shares is vested, provided however
         that should the Employee cease to remain in service to the Company
         while holding one or more unvested shares of Restricted Stock, such
         unvested shares will be immediately surrendered to the Corporation for
         cancellation and the Employee will have no further stockholder rights
         with respect to such unvested shares.

                                (v)   In the event of a Change in Control or
         Corporate Transaction, as those terms are defined in the
         Option/Issuance Plan, unvested shares of Restricted Stock shall
         accelerate to the same extent that options are accelerated under the
         Option/Issuance Plan. Additionally, the terms of the loan to the
         Employee and of the Note will not be affected by such Change in Control
         or Corporate Transaction, so that the Company or the successor
         corporation, whichever is applicable, will continue to lend to the
         Employee such funds as are described herein upon acceleration or upon
         vesting of Employee's interest in the securities to the extent such
         acceleration occurs.

                                       2

                           (d)  LOAN. If the Employee elects treatment under
Section 83(b) of the Internal Revenue Code for income he may be deemed to have
received in connection with his purchase of all of the shares of Restricted
Stock, the Company will loan the Employee One Million Dollars ($1,000,000.00) in
exchange for a full-recourse promissory note from the Employee (the "Note"),
subject to the following terms and conditions:

                                (i) The Company will fund such loan to the
         Employee in the principal amount no later than fifteen (15) business
         days following the Employee's purchase of the Restricted Stock.

                                (ii) The Note will accrue interest at the
         applicable federal rate for mid-term loans of 6.02%, compounded
         annually, and shall have a term of six (6) years. Payment on the
         outstanding principal and all accrued interest will be due on the
         maturity date. The Note will be secured by the Restricted Stock and/or
         such other collateral (if any) as the officer executing the security
         agreement deems appropriate. In the event that the Employee terminates
         his service with the Company before the term of the Note has lapsed,
         the Note will become due and payable in full within thirty (30) days of
         such termination.

                           (e)  STOCK OPTIONS. The Company hereby agrees grant
to the Employee, as of the Effective Date, options to purchase 1,100,000 shares
of the Corporation's Common Stock, 500,000 of which (the "Plan Options") are to
be granted pursuant to the Option/Stock Issuance Plan and 600,000 of which (the
"Non-Plan Options") are to be granted under an option agreement between the
Corporation and the Employee, which agreement is attached as EXHIBIT A (the
"Option Agreement"). All of the granted options shall be subject to the
following terms:

                                (i) The Plan Options shall be considered
         Incentive Stock Options to the maximum extent permitted in each
         calendar year under Section 422(d) of the Internal Revenue Code of
         1986, as amended. All other of the options granted shall be
         non-statutory stock options.

                                (ii) All options shall have a term of ten (10)
         years from the Effective Date, subject to earlier termination following
         the optionee's cessation of service with the Company. The exercise
         price of the options granted shall be equal to the closing price per
         share on the Effective Date, as such price is reported by the Nasdaq
         Stock Market, which price is deemed for purposes of the Option/Issuance
         Plan and the Option Agreement to be the fair market value per share of
         Common Stock as of the Effective Date.

                                (iii) One-quarter of the shares covered by such
         options shall become exercisable on the anniversary of the Effective
         Date and 1/48 of the shares covered by such options shall become
         exercisable upon the day corresponding to the Effective Date of each of
         the thirty-six months following the first anniversary of the Effective
         Date, so that the options will be fully exercisable on the fourth
         anniversary of the Effective Date in 2003.

                                       3

                                (iv) Should the Employee for any reason (other
         than for Cause, as defined in Section 6 of this Agreement) cease to
         remain in Service (as defined in the applicable option agreement) to
         the Corporation while such options are outstanding, then the Employee
         shall have a period of time as specified in the option agreements for
         the Plan Options and the Non-Plan Options during which to exercise such
         options, but in no event shall such options be exercisable at any time
         after their expiration date.

                                (v)  In each fiscal year of the Company that the
         Employee chooses to exercise such options, he shall exercise those
         options that are exercisable in the following order:

                                     (A) First, the Employee shall exercise
                  exercisable Non-Plan Options until the aggregate spread
                  between the exercise price and the fair market value of option
                  shares on the date of exercise is equal to any excess of One
                  Million Dollars ($1,000,000.00) over the amount of
                  compensation other than from exercise of Plan Options that the
                  Employee reasonably expects to receive in such fiscal year.

                                     (B) Second, the Employee shall exercise
                  exercisable Plan Options.

                                     (C) The Employee shall not exercise
                  additional Non-Plan Options in such fiscal year until he has
                  exercised all of his then exercisable Plan Options.

                                (vi) The remaining terms and conditions of such
         Plan Options shall be substantially as set forth in the Company's
         standard form option agreement and the Option/Issuance Plan and the
         remaining terms and conditions of the Non-Plan options are as set forth
         in the Option Agreement in EXHIBIT A.

                           3.   VACATION AND EMPLOYEE BENEFITS. During the term
of his Employment, the Employee shall be eligible for four weeks of paid
vacation per year of Employment. During the term of his Employment, the Employee
shall be eligible to participate in any employee benefit plans maintained by the
Company for senior executives, subject in each case to the generally applicable
terms and conditions of the plan in question and to the determinations of any
person or committee administering such plan. In addition, the Company will
reimburse Employee for the costs of membership in a health club of his choice.

                           4.   BUSINESS EXPENSES. During the term of his
Employment, the Employee shall be authorized to incur necessary and reasonable
travel (including first class air travel), entertainment and other business
expenses in connection with his duties hereunder. The Company shall reimburse
the Employee for such expenses upon presentation of an itemized account and
appropriate supporting documentation, all in accordance with the Company's
generally applicable policies. For a period of two years from the date of this
Agreement, the Company will also reimburse Employee for all travel between his
family residence in Southern California and Hyperion locations in conjunction
with Company business and provide Employee

with temporary living arrangements near such office of the Company as shall be
agreed upon by the Board and the Employee. Should Employee decide within the
first two years of his Employment to relocate his family to the vicinity of such
office of the Company as shall be agreed upon by the Board and the Employee, the
Company will reimburse Employee for all reasonable and customary expenses
associated with the relocation. This includes, but is not limited to, closing
costs associated with the sale of and purchase of a home, mortgage loan closing
costs and moving costs.

                  5.       TERM OF EMPLOYMENT.

                           (a)  BASIC RULE. The Company agrees to continue the
Employee's  Employment,  and the Employee agrees to remain in Employment with
the Company, from the Effective Date until the earlier of:

                                (i)  The close of the  applicable  Initial Term
         or Renewal  Period, as determined under Subsection (b) below; or

                                (ii) The date when the Employee's Employment
         terminates pursuant to Subsection (c) below.

                           (b)  INITIAL TERM AND RENEWAL PERIODS. The initial
term of this  Agreement  shall end on October 11, 2001 (the "Initial Term").
Thereafter this Agreement shall automatically be renewed for successive 12-month
periods (the "Renewal Periods"), unless either party has given the other party
written notice of non-renewal not less than 90 days prior to the close of the
Initial Term or Renewal Period then in effect.

                           (c)  EARLY TERMINATION. The Employee may terminate
his Employment at any time other than under Section 5(b) and for any reason (or
no reason) by giving the Company 30 days advance notice in writing. The Company
may terminate the Employee's Employment at any time and for any reason (or no
reason), and with or without Cause, by giving the Employee 30 days advance
notice in writing or, at the Company's option, pay in lieu of some or all of the
notice period. The Company may also, subject to applicable laws, terminate the
Employee's active Employment due to Disability by giving the Employee notice in
writing. For all purposes under this Agreement, "Disability" shall mean a
"disability" as defined by the Americans with Disabilities Act that renders the
Employee unable to perform one or more of the essential functions of his job and
which the Company is unable to accommodate reasonably without undue hardship.
The Employee's Employment shall terminate automatically in the event of his
death.

                           (d)  EMPLOYMENT AT WILL. At all times, the Employee's
Employment with the Company shall be "at will." Any contrary representations
which may have been made to the Employee shall be superseded by this Agreement.
This Agreement shall constitute the full and complete agreement between the
Employee and the Company on the "at will" nature of the Employee's Employment,
which may only be changed in an express written agreement signed by the Employee
and a duly authorized officer of the Company.

                           (e)  RIGHTS AND OBLIGATIONS UPON TERMINATION. Except
as expressly

                                       5
<PAGE>   6


provided in Section 6, upon the termination of the Employee's Employment
pursuant to this Section 5, the Employee shall only be entitled to the
compensation, benefits and reimbursements described in Sections 2, 3 and 4 for
the period preceding the effective date of the termination. No incentive bonus
under Section 2(b) shall be payable for the year in which the Employee's
Employment terminates, unless the Employee is terminated without Cause, in which
the case the Employee shall be entitled to the payment of a prorated bonus for
such year. The payments under this Agreement shall fully discharge all
compensatory obligations of the Company to the Employee. The termination of this
Agreement shall not limit or otherwise affect the Employee's obligations under
Section 7. The Employee will also be required to repay the Note pursuant to
Section 2(d)(ii).

                           (f)  COVENANT. Employee hereby agrees to resign
immediately  upon the request of the Company from all offices and directorships
he may hold with the Company or any of its affiliates upon the termination of
his Employment for any reason.

                  6.       TERMINATION BENEFITS.

                           (a)  GENERAL MUTUAL RELEASE. Within seven (7) days of
the Employee's termination date, the Employee shall execute a general release
(in a form prescribed by the Company) of all known and unknown claims that he
may then have against the Company or persons affiliated with the Company and the
Company also agrees to provide the Employee with the same general release and
agreement for the benefit of the Employee.

                           (b)  SEVERANCE PAY. Any other provision of this
Agreement notwithstanding, this Section (b) and Section (c) below shall not
apply unless (x) the Employee has executed the general release pursuant to
subsection (a) above, and (y) the Employee has agreed not to (and does not)
prosecute any legal action or other proceeding based upon any of such claims. If
such conditions are met, the Company shall pay the Employee his Base
Compensation for a thirty (30)-month period following the effective date of the
termination of his Employment as a full-time employee (the "Continuation
Period"), provided the Employee does not breach any provision of this Agreement
and:

                                (i) The Company terminates the Employee's
         Employment as a full-time employee under Section 5(b) or Section 5(c)
         for any reason other than Cause, Disability or death; or

                                (ii) The Employee resigns his Employment as
         a full-time employee for Good Reason within 12 months following a
         Change in Control, as defined below.

The Base Compensation under this Subsection (b) shall be paid at the rate in
effect at the time of the termination of Employment and in accordance with the
Company's standard payroll procedures.

The Company reserves the right to pay such severance pay to the Employee in any
combination of the following: x) cash; y) by accelerating vesting in some or all
of those shares of Restricted Stock that are unvested as of the termination
date; and z) by accelerating vesting in some or all of

                                       6
<PAGE>   7


such stock options granted to the Employee that remain unvested as of the
termination date.

If the Company so chooses to accelerate vesting of either or both the Restricted
Stock and such stock options, the value of such Restricted Stock or stock option
shares will be calculated using the average of the closing trade price of the
Company's Common Stock for the twenty (20) trading days preceding the Employee's
termination date (the "Average Price"). The value of such severance pay which
the Company chooses to pay in the form of such accelerated Restricted Stock, if
any, will be equal to the number of shares so accelerated multiplied by the
excess of the Average Price over $0.001. The value of such severance pay which
the Company chooses to pay in the form of such accelerated stock option shares,
if any, will be equal to the number of shares so accelerated multiplied by the
excess of the Average Price over the exercise price of the stock option shares.

                           (c)  EMPLOYEE BENEFITS. If Subsection (b) above
applies, the Company shall continue the coverage of the Employee and his
dependents (if applicable) under the employee benefit plans described in Section
3 during the Continuation Period. To the extent that such plans or the insurance
contracts or provider agreements associated with such plans do not permit the
extension of the Employee's coverage following the termination of his active
employment, the Company shall pay the Employee cash in an amount equal to the
cost to the Company of the coverage that cannot be provided. The cash payments
shall be made in accordance with Subsection (b) above.

                           (d)  COBRA. If Subsection (b) above applies, and if
the Employee elects to continue his health insurance coverage under the
Consolidated Omnibus Budget Reconciliation Act ("COBRA") following the
termination of his Employment, then the date of the "qualifying event" for
purposes of COBRA shall be the Employee's last day of active employment.

                           (e)  DEFINITION OF "CAUSE." For all purposes under
this Agreement, "Cause" shall mean:

                                (i) The Employee's failure to perform in a
         satisfactory  fashion one or more reasonable and lawful duties assigned
         to the Employee by the Company under this Agreement, if such failure
         continues for 15 days or more after the Company has given the Employee
         written notice describing such failure and advising him of the
         consequences of such failure under this Agreement, provided that such
         notice shall be required only with respect to the first failure;

                                (ii) The Employee's conviction of, or a plea
         of "guilty" or "no contest" to, a felony under the laws of the United
         States or any state thereof;

                                (iii) The Employee's failure or refusal to
         carry out the reasonable directives of the Company, if such failure
         continues for three days or more after the Company has given the
         Employee written notice describing such failure and advising him of the
         consequences of such failure under this Agreement, provided that such
         notice shall be required only with respect to the

                                       7
<PAGE>   8

         first failure;

                                (iv) Any breach of this Agreement, the
         Proprietary Information and Inventions Agreement between the Employee
         and the Company, or any other agreement between the Employee and the
         Company;

                                (v)  Threats or acts of violence directed at any
         present, former or prospective employee, independent contractor,
         vendor, customer or business partner of the Company (or any of the
         Company's affiliates); or

                                (vi) The commission of any act of fraud,
         embezzlement or dishonesty by Employee, any unauthorized use or
         disclosure by Employee of confidential information or trade secrets of
         the Company (or any of the Company's affiliates), or any other
         intentional misconduct by Employee affecting the business or affairs of
         the Company (or any of the Company's affiliates) in a material manner.

                           (f)  DEFINITION OF "CHANGE IN CONTROL." For all
purposes under this Agreement except where indicated in Section 2(c), "Change
in Control" shall mean:

                                (i) The consummation of a merger or
         consolidation of the Company with or into another entity or any other
         corporate reorganization, if persons who were not stockholders of the
         Company immediately prior to such transaction own immediately after
         such transaction 50% or more of the voting power of the outstanding
         securities of each of (A) the continuing or surviving entity or (B) any

change the state of the Company's incorporation or to create a holding company
that will be owned in substantially the same proportions by the persons who held
the Company's securities immediately before such transaction.

                           (g)  DEFINITION OF "GOOD REASON." For all purposes
under this Agreement, "Good Reason" shall mean:

                                (i) A significant diminution in the nature or

         Base Compensation in effect immediately prior to the Change in Control

         principal place of employment immediately prior to the Change in
         Control; or

                                (iv) An increase of 25% or more in the
         average amount of time per month that the Employee is required to be
         away from his principal place of employment, relative to the average
         amount of time per month that the Employee was required to be away from
         his principal place of employment immediately prior to the Change in
         Control.

                        EFFECTIVE AS OF OCTOBER 11, 1999

RECITALS

A.       The Board has adopted the Plan for the purpose of retaining the
services of selected Employees, non-employee members of the Board or the board
of directors of any Parent or Subsidiary and consultants and other independent
advisors who provide services to the Corporation (or any Parent or Subsidiary).

B.       Optionee is to render valuable services to the Corporation (or a Parent
or Subsidiary), and this Agreement is executed pursuant to, and is intended to
carry out the purposes of, the Plan in connection with the Corporation's grant
of an option to Optionee.

C.       All capitalized terms in this Agreement shall have the meaning assigned
to them in the attached Appendix.

                 NOW, THEREFORE, it is hereby agreed as follows:

                  1. GRANT OF OPTION. The Corporation hereby grants to Optionee,
as of the Grant Date, an option to purchase up to the number of Option Shares
specified in the Grant Notice. The Option Shares shall be purchasable from time
to time during the option term specified in Paragraph 2 at the Exercise Price.

                  2. OPTION TERM. This option shall have a term of ten (10)
years measured from the Grant Date and shall accordingly expire at the close of
business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5 or 6.

                  3. LIMITED TRANSFERABILITY. This option shall be neither
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution following Optionee's death and may be exercised, during
Optionee's lifetime, only by Optionee.

                  4. DATES OF EXERCISE.

                           i) This option shall become exercisable for the
                  Option Shares in one or more installments as specified in the
                  Grant Notice. As the option becomes exercisable for such
                  installments, those installments shall accumulate and the
                  option shall remain exercisable for the accumulated
                  installments until the Expiration Date or sooner termination
                  of the option term under Paragraph 5 or 6.

<PAGE>   16
                           ii) In each fiscal year of the Company that the
                  Optionee chooses to exercise such options, he shall exercise
                  those options that are exercisable in the following order:

                                    (A) First, the Optionee shall exercise
                           exercisable Non-Plan Options until the aggregate
                           spread between the exercise price and the fair market
                           value of option shares on the date of exercise is
                           equal to any excess of One Million Dollars
                           ($1,000,000.00) over the amount of compensation other
                           than from exercise of Plan Options that the Optionee
                           reasonably expects to receive in such fiscal year.

                                    (B) Second, the Optionee shall exercise
                           exercisable Plan Options.

                                    (C) The Optionee shall not exercise
                           additional Non-Plan Options in such fiscal year until
                           he has exercised all of his then exercisable Plan
                           Options.

                  5. CESSATION OF SERVICE. The option term specified in
Paragraph 2 shall terminate (and this option shall cease to be outstanding)
prior to the Expiration Date should any of the following provisions become
applicable:

                  (i) Should Optionee cease to remain in Service for any reason
         (other than death, Permanent Disability or Cause) while this option is
         outstanding, then Optionee shall have a period of three (3) months
         (commencing with the date of such cessation of Service) ), or such
         period of time greater than three (3) months as may be determined by
         the Board to be in the best interests of the Corporation, during which

         then the personal representative of Optionee's estate or the person or
         persons to whom the option is transferred pursuant to Optionee's will
         or in accordance with the laws of descent and distribution shall have
         the right to exercise this option. Such right shall lapse and this
         option shall cease to be outstanding upon the earlier of (A) the
         expiration of the twelve (12)- month period measured from the date of
         Optionee's death or (B) the Expiration Date.

                  (iii) Should Optionee cease Service by reason of Permanent

<PAGE>   17
                  (iv) Should Optionee's Service be terminated for Cause, then
         this option shall terminate immediately and cease to remain
         outstanding.

                  (v) During the limited period of post-Service exercisability,
         this option may not be exercised in the aggregate for more than the
         number of vested Option Shares for which the option is exercisable at
         the time of Optionee's cessation of Service. Upon the expiration of
         such limited exercise period or (if earlier) upon the Expiration Date,
         this option shall terminate and cease to be outstanding for any vested
         Option Shares for which the option has not been exercised. To the
         extent Optionee is not vested in the Option Shares at the time of
         Optionee's cessation of Service, this option shall immediately
         terminate and cease to be outstanding with respect to those shares.

                  (vi) In the event of a Corporate Transaction, the provisions
         of Paragraph 6 shall govern the period for which this option is to
         remain exercisable following Optionee's cessation of Service and shall
         supersede any provisions to the contrary in this paragraph.

                  6.       SPECIAL ACCELERATION OF OPTION.



                           a. In the event of a Corporate Transaction, the
                  exercisability of this option, to the extent outstanding at
                  such time but not otherwise fully exercisable, shall
                  automatically accelerate so that this option shall,
                  immediately prior to the effective date of the Corporate
                  Transaction, become exercisable for any or all of the Option
                  Shares at the time subject to this option as fully-vested
                  shares of Common Stock. No such acceleration of this option,
                  however, shall occur if and to the extent: (i) this option is,
                  in connection with the Corporate Transaction, either to be
                  assumed by the successor corporation (or parent thereof) or to
                  be replaced with a comparable option to purchase shares of the
                  capital stock of the successor corporation (or parent thereof)
                  or (ii) this option is to be replaced with a cash incentive
                  program of the successor corporation which preserves the
                  spread existing on the Option Shares for which this option is
                  not exercisable at the time of the Corporate Transaction (the
                  excess of the Fair Market Value of such Option Shares over the
                  aggregate Exercise Price payable for such shares) and provides
                  for subsequent pay-out in accordance with the same exercise
                  schedule in effect for the option pursuant to the option
                  exercise schedule set forth in the Grant Notice. The
                  determination of option comparability under clause (i) shall
                  be made by the Plan Administrator, and such determination
                  shall be final, binding and conclusive.

                           b. Immediately following the Corporate Transaction,
                  this option, to the extent not previously exercised, shall
                  terminate and cease to be outstanding, except to the extent
                  assumed by the successor corporation (or parent thereof) in
                  connection with the Corporate Transaction.

<PAGE>   18
                           c. If this option is assumed in connection with a
                  Corporate Transaction, then this option shall be appropriately
                  adjusted, immediately after such Corporate Transaction, to
                  apply to the number and class of securities which would have
                  been issuable to Optionee in consummation of such Corporate
                  Transaction had the option been exercised immediately prior to
                  such Corporate Transaction, and appropriate adjustments shall
                  also be made to the Exercise Price, provided the aggregate
                  Exercise Price shall remain the same.

                           d. Upon an Involuntary Termination of Optionee's
                  Service within eighteen (18) months following a Corporate
                  Transaction in which this option is assumed or replaced, the
                  exercisability of this option, to the extent outstanding at
                  such time but not otherwise fully exercisable, shall
                  automatically accelerate so that this option shall immediately
                  become fully exercisable for all the Option Shares at the time
                  subject to this option as fully-vested shares of Common Stock
                  and may be exercised for any or all of those shares at any
                  time prior to the earlier of (i) the Expiration Date or (ii)
                  the expiration of the one (1)-year period measured from the
                  effective date of the Involuntary Termination.

                           e. This Agreement shall not in any way affect the
                  right of the Corporation to adjust, reclassify, reorganize or
                  otherwise change its capital or business structure or to
                  merge, consolidate, dissolve, liquidate or sell or transfer
                  all or any part of its business or assets.

                  7. ADJUSTMENT IN OPTION SHARES. Should any change be made to
the Common Stock by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be made to (i) the total number
and/or class of securities subject to this option and (ii) the Exercise Price in
order to reflect such change and thereby preclude a dilution or enlargement of
benefits hereunder.

                  8. STOCKHOLDER RIGHTS. The holder of this option shall not
have any stockholder rights with respect to the Option Shares until such person
shall have exercised the option, paid the Exercise Price and become a holder of
record of the purchased shares.

                  9. MANNER OF EXERCISING OPTION.

                  a. In order to exercise this option with respect to all or any
         part of the Option Shares for which this option is at the time
         exercisable, Optionee (or any other person or persons exercising the
         option) must take the following actions:

                           (i) Execute and deliver to the Corporation a Notice
                  of Exercise for the Option Shares for which the option is
                  exercised.


                                     PAGE 4
<PAGE>   19
                           (ii) Pay the aggregate Exercise Price for the
                  purchased shares in one or more of the following forms:

                                    (A) cash or check made payable to the
                           Corporation;

                                    (B) a promissory note payable to the
                           Corporation, but only to the extent authorized by the
                           Plan Administrator in accordance with Paragraph 13;

                                    (C) shares of Common Stock held by Optionee
                           (or any other person or persons exercising the
                           option) for the requisite period necessary to avoid a
                           charge to the Corporation's earnings for financial
                           reporting purposes and valued at Fair Market Value on
                           the Exercise Date; or

                                    (D) through a special sale and remittance
                           procedure pursuant to which Optionee (or any other
                           person or persons exercising the option) shall
                           concurrently provide irrevocable written instructions
                           (I) to a Corporation-designated brokerage firm to
                           effect the immediate sale of the purchased shares and
                           remit to the Corporation, out of the sale proceeds
                           available on the settlement date, sufficient funds to
                           cover the aggregate Exercise Price payable for the
                           purchased shares plus all applicable Federal, state
                           and local income and employment taxes required to be
                           withheld by the Corporation by reason of such
                           exercise and (II) to the Corporation to deliver the
                           certificates for the purchased shares directly to
                           such brokerage firm in order to complete the sale
                           transaction.

                           Except to the extent the sale and remittance
         procedure is utilized in connection with the option exercise, payment
         of the Exercise Price must accompany the Notice of Exercise delivered
         to the Corporation in connection with the option exercise.

                                    (iii) Furnish to the Corporation appropriate
                           documentation that the person or persons exercising
                           the option (if other than Optionee) have the right to
                           exercise this option.

                                    (iv) Make appropriate arrangements with the
                           Corporation (or Parent or Subsidiary employing or
                           retaining Optionee) for the satisfaction of all
                           Federal, state and local income and employment tax
                           withholding requirements applicable to the option
                           exercise.

                  b. As soon as practical after the Exercise Date, the
         Corporation shall issue to or on behalf of Optionee (or any other
         person or persons


                                     PAGE 5
<PAGE>   20
         exercising this option) a certificate for the purchased Option Shares,
         with the appropriate legends affixed thereto.

                  c. In no event may this option be exercised for any fractional
         shares.

                  10. COMPLIANCE WITH LAWS AND REGULATIONS.

                  a. The exercise of this option and the issuance of the Option
         Shares upon such exercise shall be subject to compliance by the
         Corporation and Optionee with all applicable requirements of law
         relating thereto and with all applicable regulations of any stock
         exchange (or the Nasdaq National Market, if applicable) on which the
         Common Stock may be listed for trading at the time of such exercise and
         issuance.

                  b. The inability of the Corporation to obtain approval from
         any regulatory body having authority deemed by the Corporation to be
         necessary to the lawful issuance and sale of any Common Stock pursuant
         to this option shall relieve the Corporation of any liability with
         respect to the non-issuance or sale of the Common Stock as to which
         such approval shall not have been obtained. The Corporation, however,
         shall use its best efforts to obtain all such approvals.

                  11. SUCCESSORS AND ASSIGNS. Except to the extent otherwise
provided in Paragraphs 3 and 6, the provisions of this Agreement shall inure to
the benefit of, and be binding upon, the Corporation and its successors and
assigns and Optionee, Optionee's assigns and the legal representatives, heirs
and legatees of Optionee's estate.

                  12. NOTICES. Any notice required to be given or delivered to
the Corporation under the terms of this Agreement shall be in writing and
addressed to the Corporation at its principal corporate offices. Any notice
required to be given or delivered to Optionee shall be in writing and addressed
to Optionee at the address indicated below Optionee's signature line on the
Grant Notice. All notices shall be deemed effective upon personal delivery or
upon deposit in the U.S. mail, postage prepaid and properly addressed to the
party to be notified.

                  13. FINANCING. The Plan Administrator may, in its absolute
discretion and without any obligation to do so, permit Optionee to pay the
Exercise Price for the purchased Option Shares by delivering a promissory note.
The terms of any such promissory note (including the interest rate, the
requirements for collateral and the terms of repayment) shall be established by
the Plan Administrator in its sole discretion.(1)

(1) Authorization of payment of the Exercise Price by a promissory note may,
    under currently proposed Treasury Regulations, result in the loss of
    incentive stock option treatment under the Federal tax laws.

                                     PAGE 6
<PAGE>   21
                  14. CONSTRUCTION. This Agreement and the option evidenced
hereby are made and granted pursuant to the Plan and are in all respects limited
by and subject to the terms of the Plan. All decisions of the Plan Administrator
with respect to any question or issue arising under the Plan or this Agreement
shall be conclusive and binding on all persons having an interest in this
option.

                  15. GOVERNING LAW. The interpretation, performance and
enforcement of this Agreement shall be governed by the laws of the State of
California without resort to that State's conflict-of-laws rules.

                  16. EXCESS SHARES. If the Option Shares covered by this
Agreement exceed, as of the Grant Date, the number of shares of Common Stock
which may without stockholder approval be issued under the Plan, then this
option shall be void with respect to such excess shares, unless stockholder
approval of an amendment sufficiently increasing the number of shares of Common
Stock issuable under the Plan is obtained in accordance with the provisions of
the Plan.

                  17. ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE OPTION. In the
event this option is designated an Incentive Option in the Grant Notice, the
following terms and conditions shall also apply to the grant:

                           (i) This option shall cease to qualify for favorable
                  tax treatment as an Incentive Option if (and to the extent)
                  this option is exercised for one or more Option Shares: (A)
                  more than three (3) months after the date Optionee ceases to
                  be an Employee for any reason other than death or Permanent
                  Disability or (B) more than twelve (12) months after the date
                  Optionee ceases to be an Employee by reason of Permanent
                  Disability.

                           (ii) No installment under this option shall qualify
                  for favorable tax treatment as an Incentive Option if (and to
                  the extent) the aggregate Fair Market Value (determined at the
                  Grant Date) of the Common Stock for which such installment
                  first becomes exercisable hereunder would, when added to the
                  aggregate value (determined as of the respective date or dates
                  of grant) of any earlier installments of the Common Stock and
                  any other securities for which this option or any other
                  Incentive Options granted to Optionee prior to the Grant Date
                  (whether under the Plan or any other option plan of the
                  Corporation or any Parent or Subsidiary) first become
                  exercisable during the same calendar year, exceed One Hundred
                  Thousand Dollars ($100,000) in the aggregate. Should such One
                  Hundred Thousand Dollar ($100,000) limitation be exceeded in
                  any calendar year, this option shall nevertheless become
                  exercisable for the excess shares in such calendar year as a
                  Non-Statutory Option.

                           (iii) Should the exercisability of this option be
                  accelerated upon a Corporate Transaction, then this option
                  shall qualify for favorable tax treatment as an Incentive
                  Option only to the extent the aggregate Fair Market Value
                  (determined at the Grant Date) of the Common Stock for


                                     PAGE 7
<PAGE>   22
                  which this option first becomes exercisable in the calendar
                  year in which the Corporate Transaction occurs does not, when
                  added to the aggregate value (determined as of the respective
                  date or dates of grant) of the Common Stock or other
                  securities for which this option or one or more other
                  Incentive Options granted to Optionee prior to the Grant Date
                  (whether under the Plan or any other option plan of the
                  Corporation or any Parent or Subsidiary) first become
                  exercisable during the same calendar year, exceed One Hundred
                  Thousand Dollars ($100,000) in the aggregate. Should the
                  applicable One Hundred Thousand Dollar ($100,000) limitation
                  be exceeded in the calendar year of such Corporate
                  Transaction, the option may nevertheless be exercised for the
                  excess shares in such calendar year as a Non-Statutory Option.

                           (iv) Should Optionee hold, in addition to this
                  option, one or more other options to purchase Common Stock
                  which become exercisable for the first time in the same
                  calendar year as this option, then the foregoing limitations
                  on the exercisability of such options as Incentive Options
                  shall be applied on the basis of the order in which such
                  options are granted.

         18. COUNTERPARTS. This Agreement may be executed in two counterparts,
each of which shall be deemed an original, and all of which together shall
constitute one and the same instrument.

                             STOCK OPTION AGREEMENT

               - RELATING TO AN OPTION GRANT OF 600,000 SHARES -

                        EFFECTIVE AS OF OCTOBER 11, 1999

RECITALS

         A. The Compensation Committee has approved this Stock Option Agreement
for the purpose of retaining the services of JEFFREY R. RODEK (the "Optionee").

         B. Optionee is to render valuable services to the Corporation (or a
Parent or Subsidiary), and this Agreement is intended to promote the interests
of the Corporation by providing Optionee with the opportunity to acquire a
proprietary interest, or otherwise increase his proprietary interest, in the
Corporation as an incentive for him to remain in the service of the Corporation.

         C. All capitalized terms in this Agreement shall have the meaning
assigned to them in the attached Appendix.

                 NOW, THEREFORE, it is hereby agreed as follows:

                  1. GRANT OF OPTION. The Corporation hereby grants to Optionee,
as of the Grant Date, an option to purchase up to the number of Option Shares
specified in the Grant Notice. The option granted herein shall be a
Non-Statutory Option. The Option Shares shall be purchasable from time to time
during the option term specified in Paragraph 2 at the Exercise Price.

                  2. OPTION TERM. This option shall have a term of ten (10)
years measured from the Grant Date and shall accordingly expire at the close of
business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5 or 6.

                  3. LIMITED TRANSFERABILITY. This option shall be neither
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution following Optionee's death and may be exercised, during
Optionee's lifetime, only by Optionee. However, this option may be assigned in
whole or in part during the Optionee's lifetime in accordance with the terms of
a Qualified Domestic Relations Order. The assigned portion may only be exercised
by the person or persons who acquire a proprietary interest in the option
pursuant to such Qualified Domestic Relations Order. The terms applicable to the
assigned portion shall be the same as those in effect for the option immediately
prior to such assignment and shall be set forth in such documents issued to the
assignee as the Compensation Committee may deem appropriate.

                  4. DATES OF EXERCISE.


                                       1
<PAGE>   31
                  i) This option shall become exercisable for the Option Shares
         in one or more installments as specified in the Grant Notice. As the
         option becomes exercisable for such installments, those installments
         shall accumulate and the option shall remain exercisable for the
         accumulated installments until the Expiration Date or sooner
         termination of the option term under Paragraph 5 or 6.

                  (ii) In each fiscal year of the Company that the Optionee
         chooses to exercise this option, he shall exercise those Option Shares
         that are exercisable in the following order:

                           (A) First, the Optionee shall exercise exercisable
                  Non-Plan Options until the aggregate spread between the
                  exercise price and the fair market value of option shares on
                  the date of exercise is equal to any excess of One Million
                  Dollars ($1,000,000.00) over the amount of compensation other
                  than from exercise of Plan Options that the Optionee
                  reasonably expects to receive in such fiscal year.

                           (B) Second, the Optionee shall exercise exercisable
                  Plan Options.

                           (C) The Optionee shall not exercise additional
                  Non-Plan Options in such fiscal year until he has exercised
                  all of his then exercisable Plan Options.

                  5.       CESSATION OF SERVICE. The option term specified in
Paragraph 2 shall terminate (and this option shall cease to be outstanding)
prior to the Expiration Date should any of the following provisions become
applicable:

                           (i) Should Optionee cease to remain in Service for
                  any reason (other than death or for Cause) while this option
                  is outstanding, then Optionee shall have a period of three (3)
                  months (commencing with the date of such cessation of
                  Service), or such period of time greater than three (3) months
                  as may be determined by the Board to be in the best interests
                  of the Corporation, during which to exercise this option, but
                  in no event shall this option be exercisable at any time after
                  the Expiration Date.

                           (ii) Should Optionee die while this option is
                  outstanding, then the personal representative of Optionee's
                  estate or the person or persons to whom the option is
                  transferred pursuant to Optionee's will or in accordance with
                  the laws of descent and distribution shall have the right to
                  exercise this option. Such right shall lapse and this option
                  shall cease to be outstanding upon the earlier of (A) the
                  expiration of the twelve (12)- month period measured from the
                  date of Optionee's death or (B) the Expiration Date.

                           (iii) Should Optionee cease Service by reason of
                  Permanent Disability while this option is outstanding, then
                  Optionee shall have a period of twelve (12) months (commencing
                  with the date of such cessation of Service) during which to


                                       2
<PAGE>   32
                  exercise this option. In no event shall this option be
                  exercisable at any time after the Expiration Date.

                           (iv) Should Optionee's Service be terminated for
                  Cause, then this option shall terminate immediately and cease
                  to remain outstanding.

                           (v) During the limited period of post-Service
                  exercisability, this option may not be exercised in the
                  aggregate for more than the number of vested Option Shares for
                  which the option is exercisable at the time of Optionee's
                  cessation of Service. Upon the expiration of such limited
                  exercise period or (if earlier) upon the Expiration Date, this
                  option shall terminate and cease to be outstanding for any
                  vested Option Shares for which the option has not been
                  exercised. To the extent Optionee is not vested in the Option
                  Shares at the time of Optionee's cessation of Service, this
                  option shall immediately terminate and cease to be outstanding
                  with respect to those shares.

                           (vi) In the event of a Corporate Transaction, the
                  provisions of Paragraph 6 shall govern the period for which
                  this option is to remain exercisable following Optionee's
                  cessation of Service and shall supersede any provisions to the
                  contrary in this paragraph.

                  6.       SPECIAL ACCELERATION OF OPTION.

                           (i) In the event of a Corporate Transaction, the
                  exercisability of this option, to the extent outstanding at
                  such time but not otherwise fully exercisable, shall
                  automatically accelerate so that this option shall,
                  immediately prior to the effective date of the Corporate
                  Transaction, become exercisable for any or all of the Option
                  Shares at the time subject to this option as fully-vested
                  shares of Common Stock. No such acceleration of this option,
                  however, shall occur if and to the extent: (x) this option is,
                  in connection with the Corporate Transaction, either to be
                  assumed by the successor corporation (or parent thereof) or to
                  be replaced with a comparable option to purchase shares of the
                  capital stock of the successor corporation (or parent thereof)
                  or (y) this option is to be replaced with a cash incentive
                  program of the successor corporation which preserves the
                  spread existing on the Option Shares for which this option is
                  not exercisable at the time of the Corporate Transaction (the
                  excess of the Fair Market Value of such Option Shares over the
                  aggregate Exercise Price payable for such shares) and provides
                  for subsequent pay-out in accordance with the same exercise
                  schedule in effect for the option pursuant to the option
                  exercise schedule set forth in the Grant Notice. The
                  determination of option comparability under clause (x) shall
                  be made by the Compensation Committee, and such determination
                  shall be final, binding and conclusive.

                           (ii) Immediately following the Corporate Transaction,
                  this option, to the extent not previously exercised, shall
                  terminate and cease to be outstanding, except to the extent
                  assumed by the successor corporation (or parent thereof) in
                  connection with the Corporate Transaction.


                                       3
<PAGE>   33
                           (iii) If this option is assumed in connection with a
                  Corporate Transaction, then this option shall be appropriately
                  adjusted, immediately after such Corporate Transaction, to
                  apply to the number and class of securities which would have
                  been issuable to Optionee in consummation of such Corporate
                  Transaction had the option been exercised immediately prior to
                  such Corporate Transaction, and appropriate adjustments shall
                  also be made to the Exercise Price, provided the aggregate
                  Exercise Price shall remain the same.

                           (iv) Upon an Involuntary Termination of Optionee's
                  Service within eighteen (18) months following a Corporate
                  Transaction in which this option is assumed or replaced, the
                  exercisability of this option, to the extent outstanding at
                  such time but not otherwise fully exercisable, shall
                  automatically accelerate so that this option shall immediately
                  become fully exercisable for all the Option Shares at the time
                  subject to this option as fully-vested shares of Common Stock
                  and may be exercised for any or all of those shares at any
                  time prior to the earlier of (x) the Expiration Date or (y)
                  the expiration of the one (1)-year period measured from the
                  effective date of the Involuntary Termination.

                           (v) The Compensation Committee shall have the
                  discretion, exercisable either at the time the option is
                  granted or at any time while the option remains outstanding,
                  to (x) provide for the automatic acceleration of vesting in
                  this option upon the occurrence of a Change in Control or (y)
                  condition any such option acceleration (and the termination of
                  any outstanding repurchase rights) upon the subsequent
                  Involuntary Termination within a specified period following
                  the effective date of such Change in Control. Any Option
                  Shares accelerated in connection with a Change in Control
                  shall remain fully exercisable until the expiration or sooner
                  termination of the option term.

                           (vi) This Agreement shall not in any way affect the
                  right of the Corporation to adjust, reclassify, reorganize or
                  otherwise change its capital or business structure or to
                  merge, consolidate, dissolve, liquidate or sell or transfer
                  all or any part of its business or assets.

                  7.       ADJUSTMENT IN OPTION SHARES. Should any change be
made to the Common Stock by reason of any stock split, stock dividend,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration, appropriate adjustments shall be made to (i) the total
number and/or class of securities subject to this option and (ii) the Exercise
Price in order to reflect such change and thereby preclude a dilution or
enlargement of benefits hereunder.

                  8.       STOCKHOLDER RIGHTS. The holder of this option shall
not have any stockholder rights with respect to the Option Shares until such
person shall have exercised the option, paid the Exercise Price and become a
holder of record of the purchased shares.

                  9.       MANNER OF EXERCISING OPTION.


                           (i) In order to exercise this option with respect to
                  all or any part of the Option Shares for which this option is
                  at the time exercisable, Optionee (or any other person or
                  persons exercising the option) must take the following
                  actions:

                                    A. Execute and deliver to the Corporation a
                           Notice of Exercise for the Option Shares for which
                           the option is exercised.

                                    B. Pay the aggregate Exercise Price for the
                           purchased shares in one or more of the following
                           forms:

                                             a. cash or check made payable to
                                    the Corporation;

                                             b. a promissory note payable to the
                                    Corporation, but only to the extent
                                    authorized by the Compensation Committee in
                                    accordance with Paragraph 13;

                                             c. shares of Common Stock held by
                                    Optionee (or any other person or persons
                                    exercising the option) for the requisite
                                    period necessary to avoid a charge to the
                                    Corporation's earnings for financial
                                    reporting purposes and valued at Fair Market
                                    Value on the Exercise Date; or

                                             d. through a special sale and
                                    remittance procedure pursuant to which
                                    Optionee (or any other person or persons
                                    exercising the option) shall concurrently
                                    provide irrevocable written instructions (x)
                                    to a Corporation-designated brokerage firm
                                    to effect the immediate sale of the
                                    purchased shares and remit to the
                                    Corporation, out of the sale proceeds
                                    available on the settlement date, sufficient
                                    funds to cover the aggregate Exercise Price
                                    payable for the purchased shares plus all
                                    applicable Federal, state and local income
                                    and employment taxes required to be withheld
                                    by the Corporation by reason of such
                                    exercise and (y) to the Corporation to
                                    deliver the certificates for the purchased
                                    shares directly to such brokerage firm in
                                    order to complete the sale transaction.

                  Except to the extent the sale and remittance procedure is
utilized in connection with the option exercise, payment of the Exercise Price
must accompany the Notice of Exercise delivered to the Corporation in connection
with the option exercise.

                           C. Furnish to the Corporation appropriate
                  documentation that the person or persons exercising the option
                  (if other than Optionee) have the right to exercise this
                  option.

                           D. Make appropriate arrangements with the Corporation
                  (or Parent or Subsidiary employing or retaining Optionee) for
                  the satisfaction of all Federal, state and local income and
                  employment tax withholding requirements applicable to the
                  option exercise. Such arrangements may include, but are not
                  limited to, the following:

                                    a. Stock Withholding: The election to have
                           the Corporation withhold, from the shares of Common
                           Stock otherwise issuable upon the exercise of this
                           option, a portion of those shares with an aggregate
                           Fair Market Value equal to the percentage of the
                           Taxes (not to exceed one hundred percent (100%))
                           designated by the holder.

                                    b. Stock Delivery: The election to deliver
                           to the Corporation, at the time this option is
                           exercised or the shares vest, one or more shares of
                           Common Stock previously acquired by Optionee (other
                           than in connection with the option exercise
                           triggering the Taxes) with an aggregate Fair Market
                           Value equal to the percentage of the Taxes (not to
                           exceed one hundred percent (100%)) designated by the
                           Optionee.

                  (ii) As soon as practical after the Exercise Date, the
         Corporation shall issue to or on behalf of Optionee (or any other
         person or persons exercising this option) a certificate for the
         purchased Option Shares, with the appropriate legends affixed thereto.

                  (iii) In no event may this option be exercised for any
         fractional shares.

         10.      COMPLIANCE WITH LAWS AND REGULATIONS.

                  (i) The exercise of this option and the issuance of the Option
         Shares upon such exercise shall be subject to compliance by the
         Corporation and Optionee with all applicable requirements of law
         relating thereto and with all applicable regulations of any stock
         exchange (or the Nasdaq National Market, if applicable) on which the
         Common Stock may be listed for trading at the time of such exercise and
         issuance.

                  (ii) The inability of the Corporation to obtain approval from
         any regulatory body having authority deemed by the Corporation to be
         necessary to the lawful issuance and sale of any Common Stock pursuant
         to this option shall relieve the Corporation of any liability with
         respect to the non-issuance or sale of the Common Stock as to which
         such approval shall not have been obtained. The Corporation, however,
         shall use its best efforts to obtain all such approvals.

         11.      REGISTRATION. The Company agrees to take all actions necessary
to file with the U.S. Securities and Exchange Commission, within sixty (60) days
from the date of this Agreement, a Registration Statement on Form S-8 with
respect to the shares of the


                                       6
<PAGE>   36
Company's common stock issuable upon exercise of the options pursuant to this
Agreement and to use commercially reasonable efforts to maintain the
effectiveness of such registration statement.

         12.      SUCCESSORS AND ASSIGNS. Except to the extent otherwise
provided in Paragraphs 3 and 6, the provisions of this Agreement shall inure to
the benefit of, and be binding upon, the Corporation and its successors and
assigns and Optionee, Optionee's assigns and the legal representatives, heirs
and legatees of Optionee's estate.

         13.      NOTICES. Any notice required to be given or delivered to the
Corporation under the terms of this Agreement shall be in writing and addressed
to the Corporation at its principal corporate offices. Any notice required to be
given or delivered to Optionee shall be in writing and addressed to Optionee at
the address indicated below Optionee's signature line on the Grant Notice. All
notices shall be deemed effective upon personal delivery or upon deposit in the
U.S. mail, postage prepaid and properly addressed to the party to be notified.

         14.      FINANCING. The Compensation Committee may, in its absolute
discretion and without any obligation to do so, permit Optionee to pay the
Exercise Price for the purchased Option Shares by delivering a promissory note.
The terms of any such promissory note (including the interest rate, the
requirements for collateral and the terms of repayment) shall be established by
the Compensation Committee in its sole discretion. Promissory notes may be
authorized with or without security or collateral. In all events, the maximum
credit available to the Optionee may not exceed the sum of (i) the aggregate
option exercise price or purchase price payable for the purchased shares plus
(ii) any Federal, state and local income and employment tax liability incurred
by the Optionee in connection with the option exercise. The Compensation
Committee may, in its discretion, determine that one or more such promissory
notes shall be subject to forgiveness by the Corporation in whole or in part
upon such terms as the Compensation Committee may deem appropriate.

         15.      CANCELLATION AND REGRANT OF THIS OPTION. The Compensation
Committee shall have the authority to effect, at any time and from time to time,
with the consent of the Optionee, the cancellation of any or all outstanding
Option Shares under this Agreement and to grant in substitution new options
covering the same or different number of shares of Common Stock but with an
exercise price per share based on the Fair Market Value per share of Common
Stock on the new option grant date.

         16.      CONSTRUCTION. This Agreement and the option evidenced hereby
are made and granted pursuant to resolutions approved by the Compensation
Committee and are in all respects limited by and subject to the terms of such
resolutions.

         17.      GOVERNING LAW. The interpretation, performance and enforcement
of this Agreement shall be governed by the laws of the State of California
without resort to that State's conflict-of-laws rules.

         18.      COUNTERPARTS. This Agreement may be executed in two
counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument.
