 This TRANSACTION BONUS AND RETENTION AGREEMENT (the “Agreement”), dated May 20, 2003 (the
“Effective Date”), is entered into by and among W. G. Champion Mitchell (“Employee”) and VeriSign, Inc., a Delaware corporation (“Company”). 
  
 WHEREAS, Employee is currently employed by the Company; and 
  
 WHEREAS, the Company and Employee desire to enter into an agreement to
provide for payment of a Transaction Bonus to Employee in connection with the sale of Network Solutions, Inc. (“NSI”); 
  
 NOW, THEREFORE, in consideration of the mutual promises made herein, the Company and Employee hereby agree as follows: 
  
 1. Purpose. The purpose of this Agreement is to provide an
incentive to Employee to assist in selling NSI and in the closing of the Change of Control Transaction. 
  
 2. Determination of Transaction Bonus. Upon a Change of Control Transaction, Employee shall receive a Transaction Bonus equal to:

  
 (a) When the Acquiring Party is a Financial Purchaser
- one half (1/2) of the sum of (i) two percent (2%) of any Net Consideration up to and including $50,000,000 of Net Consideration, (ii) two and one-half percent (2.5%) of any Net Consideration in excess of $50,000,000 and up to and including

 3. Distribution to Employee. Payment of the Transaction Bonus shall be made as follows: 
  
 (a) If the Net Consideration is paid in cash or common stock of the
Purchaser, then one hundred percent (100%) of the Transaction Bonus will be made to Employee in cash within fifteen (15) days of the closing of the Change of Control Transaction. 
  
 (b) If the Net Consideration is paid in a form other than cash or common stock of the Purchaser, then fifty percent (50%) of
the Transaction Bonus will be paid to Employee in cash within 15 days of the closing of the Change of Control Transaction and the remaining fifty percent (50%) of the Transaction Bonus will be paid to Employee in cash at the same time as payment is
made by the Purchaser to the Company or at such time as a negotiable security or instrument or other instrument readily convertible into cash is delivered to the Company or its agent(s). 

 (c) If the Net Consideration is paid partially in cash or common stock of the Purchaser and partially is
some other form, then a percentage of the Transaction Bonus that equals the percentage of the Net Consideration paid in cash and common stock will be paid to Employee in cash within fifteen (15) days of the closing of the Change of Control
Transaction, and the remainder of the Transaction Bonus will be paid to Employee by paying fifty percent (50%) of the said remainder of the Transaction Bonus to Employee in cash within 15 days of the closing of the Change of Control Transaction and
the remaining fifty percent (50%) of the said remainder of the Transaction Bonus to Employee in cash at the same time as payment is made by the Purchaser to the Company or at such time as a negotiable security or instrument or other instrument
readily convertible into cash is delivered to the Company or its agent(s). 
  
 4. Conditions to Payment of Transaction Bonus. 
  
 (a) Employee shall not be entitled to receive any Transaction Bonus, nor shall any Transaction Bonus vest or accrue (either in whole or in part), prior to the closing of the Change of Control Transaction. 

 
 (b) Employee shall not be entitled to receive any Transaction Bonus, nor
shall any Transaction Bonus vest or accrue (in whole or in part), unless Employee is actively employed with the Company on the closing of the Change of Control Transaction. Notwithstanding the foregoing, if Employee’s employment with the
Company is terminated by the Company without Cause on or after the earlier of (i) the execution of a letter of intent for the Change of Control Transaction or (ii) the execution of a definitive agreement for the Change of Control Transaction,
Employee shall be eligible to receive the Transaction Bonus upon the closing of the Change of Control Transaction. 
  
 (c) Notwithstanding any provisions in this Section 4 to the contrary, if Employee is entitled to any Transaction Bonus in connection with his termination
of employment Employee shall not be entitled to receive a Transaction Bonus unless Employee has executed the Release of Claims, Nonsolicitation and Confidentiality Agreement attached here to in the form of Exhibit A. 
  
 5. Retention Bonus. 
  
 (a) In the event the Change of Control Transaction has not occurred on or
prior to May 15, 2003, then Employee will receive a cash Retention Bonus of $187,500. Fifty percent (50%) of any Retention Bonus will be paid on May 31, 2003 and fifty percent (50%) of any Retention Bonus will be paid on August 31, 2003. 

 
 (b) If Employee becomes entitled to payment of a Transaction Bonus under
Section 2 above subsequent to payment of all or any portion of a Retention Bonus under this Section 5, and provided that the sum of such Transaction Bonus and such Retention Bonus exceeds $600,000, then the amount of such Transaction Bonus shall be

 6. Severance Payment. In the event that Employee is terminated without Cause prior to the earlier
of (i) the execution of a definitive agreement for the Change of Control Transaction, or (ii) one year following the date of this Agreement, then Employee will receive a cash Severance Payment of one and one-half (1 1⁄2 )_times his current annual

 Exhibit 10.1 
 QUEST SOFTWARE, INC. 
  
 1999 STOCK INCENTIVE PLAN 
 (as amended effective on October 19, 2003) 
  
 ARTICLE ONE 
 GENERAL PROVISIONS 
  
 I.    PURPOSE OF THE PLAN 
  
 This 1999 Stock Incentive Plan is intended to promote the interests of Quest Software, Inc., a California corporation, by providing eligible persons with the opportunity to acquire a proprietary interest, or otherwise increase their
proprietary interest, in the Corporation as an incentive for them to remain in the service of the Corporation. 
  
 Capitalized terms shall have the meanings assigned to such terms in the attached Appendix. 
  
 II.    STRUCTURE OF THE PLAN 
  
 A.    The Plan shall be divided into four separate equity programs: 
  
 (i)  the Discretionary Option Grant Program under
which eligible persons may, at the discretion of the Plan Administrator, be granted options to purchase shares of Common Stock, 
  
 (ii)  the Stock Issuance Program under which eligible persons may, at the discretion of the Plan Administrator, be issued shares
of Common Stock directly, either through the immediate purchase of such shares or as a bonus for services rendered the Corporation (or any Parent or Subsidiary), 
  
 (iii)  the Automatic Option Grant Program under which eligible non-employee Board members shall
automatically receive options at periodic intervals to purchase shares of Common Stock; and 
  
 (iv)  the Director Fee Option Grant Program under which non-employee Board members may elect to have all or any portion of their
annual retainer fee otherwise payable in cash applied to a special option grant. 
  
 B.    The provisions of Articles One and Six shall apply to all equity programs under the Plan and shall govern the interests of all persons under the Plan. 
  
 III.    ADMINISTRATION OF THE PLAN 
  
 A.    Prior to the Section 12 Registration Date,
the Discretionary Option Grant and Stock Issuance Programs shall be administered by the Board unless otherwise determined by the Board. Beginning with the Section 12 Registration Date, the following provisions shall govern the administration of the
Plan: 
  
 (i)  The Board shall have the
authority to administer the Discretionary Option Grant and Stock Issuance Programs with respect to Section 16 Insiders but may delegate such authority in whole or in part to the Primary Committee. 
  
 (ii)  Administration of the Discretionary Option
Grant and Stock Issuance Programs with respect to all other persons eligible to participate in those programs may, at the Board’s discretion, be vested in the Primary Committee or a Secondary Committee, or the Board may retain the power to
administer those programs with respect to all such persons. 
  
 (iii)  Administration of the Automatic Option Grant Program shall be self-executing in accordance with the terms of that program. 

 B.    Each Plan Administrator shall, within the scope of its administrative
jurisdiction under the Plan, have full power and authority subject to the provisions of the Plan: 
  
 (i)  to establish such rules as it may deem appropriate for proper administration of the Plan, to make all factual
determinations, to construe and interpret the provisions of the Plan and the awards thereunder and to resolve any and all ambiguities thereunder; 
  
 (ii)  to determine, with respect to awards made under the Discretionary Option Grant and Stock Issuance Programs, which eligible
persons are to receive such awards, the time or times when such awards are to be made, the number of shares to be covered by each such award, the vesting schedule (if any) applicable to the award, the status of a granted option as either an
Incentive Option or a Non-Statutory Option and the maximum term for which the option is to remain outstanding; 
  
 (iii)  to amend, modify or cancel any outstanding award with the consent of the holder or accelerate the vesting of such award;
and 
  
 (iv)  to take such other
discretionary actions as permitted pursuant to the terms of the applicable program. 
  
 Decisions of each Plan Administrator within the scope of its administrative functions under the Plan shall be final and binding on all parties. 
  
 C.    Members of the Primary Committee or any Secondary Committee shall serve for such period of time as the Board may
determine and may be removed by the Board at any time. The Board may also at any time terminate the functions of any Secondary Committee and reassume all powers and authority previously delegated to such committee. 
  
 D.    Service on the Primary Committee or the
Secondary Committee shall constitute service as a Board member, and members of each such committee shall accordingly be entitled to full indemnification and reimbursement as Board members for their service on such committee. No member of the Primary
Committee or the Secondary Committee shall be liable for any act or omission made in good faith with respect to the Plan or any options or stock issuances under the Plan. 
  
 IV.    ELIGIBILITY 
  
 A.    The persons eligible to participate in the Discretionary Option Grant and Stock Issuance Programs are as follows:

  
 (i)  Employees, 
  
 (ii)  non-employee members of the Board or the
board of directors of any Parent or Subsidiary, and 
  
 (iii)  consultants and other independent advisors who provide services to the Corporation (or any Parent or Subsidiary). 
  
 B.    Only non-employee Board members shall be eligible to participate in the Automatic Option Grant and Director Fee Option
Grant Programs. 
  
 V.    STOCK SUBJECT TO THE PLAN

  
 A.    The stock issuable under
the Plan shall be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Corporation on the open market. The maximum number of shares of Common Stock reserved for issuance over the term of the Plan shall
not exceed 23,500,000 shares. 
  
 B.    No one person participating in the Plan may receive options, separately exercisable stock appreciation rights and direct stock issuances for more than One Million (1,000,000) shares of Common Stock in the
aggregate per calendar year, beginning with the 1999 calendar year. 
  

 2 

 C.    Shares of Common Stock subject to outstanding options (including options
incorporated into this Plan from the Predecessor Plan) shall be available for subsequent issuance under the Plan to the extent those options expire, terminate or are cancelled for any reason prior to exercise in full. Unvested shares issued under
the Plan and subsequently repurchased by the Corporation, at the original exercise or issue price paid per share, pursuant to the Corporation’s repurchase rights under the Plan shall be added back to the number of shares of Common Stock
reserved for issuance under the Plan and shall accordingly be available for reissuance through one or more subsequent options or direct stock issuances under the Plan. However, should the exercise price of an option under the Plan be paid with
shares of Common Stock or should shares of Common Stock otherwise issuable under the Plan be withheld by the Corporation in satisfaction of the withholding taxes incurred in connection with the exercise of an option or the vesting of a stock
issuance under the Plan, then the number of shares of Common Stock available for issuance under the Plan shall be reduced by the gross number of shares for which the option is exercised or which vest under the stock issuance, and not by the net
number of shares of Common Stock issued to the holder of such option or stock issuance. Shares of Common Stock underlying one or more stock appreciation rights exercised under the Plan shall not be available for subsequent issuance.

  
 D.    If any change is 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 maximum number and/or class of securities issuable under the Plan, (ii) the number and/or class of securities by which the share reserve is to increase each calendar year pursuant to the automatic
share increase provisions of the Plan, (iii) the number and/or class of securities for which any one person may be granted options, separately exercisable stock appreciation rights and direct stock issuances under the Plan per calendar year, (iv)
the number and/or class of securities for which grants are subsequently to be made under the Automatic Option Grant Program to new and continuing non-employee Board members, (v) the number and/or class of securities and the exercise price per share
in effect under each outstanding option under the Plan and (vi) the number and/or class of securities and price per share in effect under each outstanding option incorporated into this Plan from the Predecessor Plan. Such adjustments to the
outstanding options are to be effected in a manner which shall preclude the enlargement or dilution of rights and benefits under such options. The adjustments determined by the Plan Administrator shall be final, binding and conclusive. 

 
 ARTICLE TWO 
 DISCRETIONARY OPTION GRANT PROGRAM 
  
 I.    OPTION TERMS 
  
 Each option shall be evidenced by one or more documents in the form approved by the Plan Administrator; provided, however, that each such document shall comply with the terms specified below. Each
document evidencing an Incentive Option shall, in addition, be subject to the provisions of the Plan applicable to such options. 
  
 A.    Exercise Price. 
  
 1.    The exercise price per share shall be fixed by the Plan Administrator at the time
of the option grant; provided, however, with respect to options granted prior to the Section 12 Registration Date, the exercise price per share shall not be less than eighty-five percent (85%) of the Fair Market Value per share of Common Stock on
the option grant date. 
  
 2.    The exercise price shall become immediately due upon exercise of the option and shall, subject to the provisions of Section II of Article Six and the documents evidencing the option, be payable in cash or check
made payable to the Corporation. Should the Common Stock be registered under Section 12 of the 1934 Act at the time the option is exercised, then the exercise price may also be paid as follows: 
  
 (i)  shares of Common Stock held 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 
  

 3 

 (ii)  to the extent the option is exercised for vested shares, through a
special sale and remittance procedure pursuant to which the Optionee shall concurrently provide irrevocable instructions to (a) a Corporation-approved 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 (b) the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale. 
  
 Except to the extent such sale and remittance procedure is utilized, payment of the exercise price for the purchased shares
must be made on the Exercise Date. 
  
 B.    Exercise and Term of Options.    Each option shall be exercisable at such time or times, during such period and for such number of shares as shall be determined by
the Plan Administrator and set forth in the documents evidencing the option. However, no option shall have a term in excess of ten (10) years measured from the option grant date. 
  
 C.    Cessation of Service. 
  
 1.    The following provisions shall govern the exercise
of any options outstanding at the time of the Optionee’s cessation of Service or death: 
  
 (i)  Any option outstanding at the time of the Optionee’s cessation of Service for any reason shall remain exercisable for
such period of time thereafter as shall be determined by the Plan Administrator and set forth in the documents evidencing the option, but no such option shall be exercisable after the expiration of the option term. 
  
 (ii)  Any option exercisable in whole or in part
by the Optionee at the time of death may be subsequently exercised by his or her Beneficiary. 
  
 (iii)  During the applicable post-Service exercise period, the option may not be exercised in the aggregate for more than the
number of vested shares for which the option is exercisable on the date of the Optionee’s cessation of Service. Upon the expiration of the applicable exercise period or (if earlier) upon the expiration of the option term, the option shall
terminate and cease to be outstanding for any vested shares for which the option has not been exercised. However, the option shall, immediately upon the Optionee’s cessation of Service, terminate and cease to be outstanding to the extent the
option is not otherwise at that time exercisable for vested shares. 
  
 (iv)  Should the Optionee’s Service be terminated for Misconduct or should the Optionee engage in Misconduct while his or her options are outstanding, then all such options shall terminate immediately
and cease to be outstanding. 
  
 2.    The
Plan Administrator shall have complete discretion, exercisable either at the time an option is granted or at any time while the option remains outstanding: 
  
 (i)  to extend the period of time for which the option is to remain exercisable following the Optionee’s cessation of
Service to such period of time as the Plan Administrator shall deem appropriate, but in no event beyond the expiration of the option term, and/or 
  
 (ii)  to permit the option to be exercised, during the applicable post-Service exercise period, for one or more additional
installments in which the Optionee would have vested had the Optionee continued in Service. 
  
 D.    Stockholder Rights.    The holder of an option shall have no stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a holder of record of the purchased shares. 
  
  

 4 

 E.    Repurchase Rights.    The Plan
Administrator shall have the discretion to grant options which are exercisable for unvested shares of Common Stock. Should the Optionee cease Service while holding such unvested shares, the Corporation shall have the right to repurchase, at the
exercise price paid per share, any or all of those unvested shares. The terms upon which such repurchase right shall be exercisable (including the period and procedure for exercise and the appropriate vesting schedule for the purchased shares) shall
be established by the Plan Administrator and set forth in the document evidencing such repurchase right. Prior to the Section 12 Registration Date, the Plan Administrator may not impose a vesting schedule upon any option grant or the shares of
Common Stock subject to that option which is more restrictive than twenty percent (20%) per year vesting, with the initial vesting to occur not later than one (1) year after the option grant date. However, such limitation shall not be applicable to
any option grants made to individuals who are officers of the Corporation, non-employee Board members or independent consultants. 
  
 F.    First Refusal Rights.    Until the Section 12 Registration Date, the Corporation
shall have the right of first refusal with respect to any proposed disposition by the Participant (or any successor in interest) of any shares of Common Stock issued under the Plan. Such right of first refusal shall be exercisable in accordance with
the terms established by the Plan Administrator and set forth in the document evidencing such right. 
  
 G.    Limited Transferability of Options.    During the lifetime of the Optionee,
Incentive Options shall be exercisable only by the Optionee and shall not be assignable or transferable other than to a Beneficiary following the Optionee’s death. 
  
 II.    INCENTIVE OPTIONS 
  
 The terms specified below shall be applicable to all Incentive Options. Except as modified by the provisions of this Section
II, all the provisions of Articles One, Two and Six shall be applicable to Incentive Options. Options which are specifically designated as Non-Statutory Options when issued under the Plan shall not be subject to the terms of this Section II.

  
 A.    Eligibility.    Incentive Options may only be granted to Employees. 
  
 B.    Exercise Price.    The exercise price per share shall not be less than one
hundred percent (100%) of the Fair Market Value per share of Common Stock on the option grant date. 
  
 C.    Dollar Limitation.    The aggregate Fair Market Value of the shares of Common
Stock (determined as of the respective date or dates of grant) for which one or more options granted to any Employee under the Plan (or any other option plan of the Corporation or any Parent or Subsidiary) may for the first time become exercisable
as Incentive Options during any one calendar year shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the Employee holds two (2) or more such options which become exercisable for the first time in the same calendar
year, the foregoing limitation on the exercisability of such options as Incentive Options shall be applied on the basis of the order in which such options are granted. 
  
 D.    10% Stockholder.    If any Employee to whom an
Incentive Option is granted is a 10% Stockholder, then the exercise price per share shall not be less than one hundred ten percent (110%) of the Fair Market Value per share of Common Stock on the option grant date, and the option term shall not
exceed five (5) years measured from the option grant date. 
  
 III.    CHANGE IN CONTROL/HOSTILE TAKE-OVER 
  
 A.    Each option outstanding at the time of a Change in Control but not otherwise fully-vested shall automatically accelerate so that each such option shall, immediately prior to the
effective date of the Change in Control, become exercisable for all of the shares of Common Stock at the time subject to that option and may be exercised for any or all of those shares as fully-vested shares of Common Stock. However, an outstanding
option shall not so accelerate if and to the extent: (i) such option is, in connection with the Change in Control, assumed 

  

 5 

 
or otherwise continued in full force and effect by the successor corporation (or parent thereof) pursuant to the terms of the Change in Control, (ii) such
option is replaced with a cash incentive program of the successor corporation which preserves the spread existing at the time of the Change in Control on the shares of Common Stock for which the option is not otherwise at that time exercisable and
provides for subsequent payout in accordance with the same vesting schedule applicable to those option shares or (iii) the acceleration of such option is subject to other limitations imposed by the Plan Administrator at the time of the option grant.
Each option outstanding at the time of the Change in Control shall terminate as provided in Section III.C. of this Article Two. 
  
 B.    All outstanding repurchase rights shall also terminate automatically, and the shares of Common Stock subject to those
terminated rights shall immediately vest in full, in the event of any Change in Control, except to the extent: (i) those repurchase rights are assigned to the successor corporation (or parent thereof) or otherwise continue in full force and effect
pursuant to the terms of the Change in Control or (ii) such accelerated vesting is precluded by other limitations imposed by the Plan Administrator at the time the repurchase right is issued. 
  
 C.    Immediately following the consummation of
the Change in Control, all outstanding options shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof) or otherwise expressly continued in full force and effect pursuant to the terms
of the Change in Control. 
  
 D.    Each option which is assumed in connection with a Change in Control shall be appropriately adjusted, immediately after such Change in Control, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Change in Control had the option been exercised immediately prior to such Change in Control. Appropriate adjustments to reflect such Change in Control shall also be made to (i) the exercise price
payable per share under each outstanding option, provided the aggregate exercise price payable for such securities shall remain the same, (ii) the maximum number and/or class of securities available for issuance over the remaining term of the
Plan and (iii) the maximum number and/or class of securities for which any one person may be granted options, separately exercisable stock appreciation rights and direct stock issuances under the Plan per calendar year. 
  
 E.    The Plan Administrator may at any time
provide that one or more options will automatically accelerate in connection with a Change in Control, whether or not those options are assumed or otherwise continued in full force and effect pursuant to the terms of the Change in Control. Any such
option shall accordingly become exercisable, immediately prior to the effective date of such Change in Control, for all of the shares of Common Stock at the time subject to that option and may be exercised for any or all of those shares as
fully-vested shares of Common Stock. In addition, the Plan Administrator may at any time provide that one or more of the Corporation’s repurchase rights shall not be assignable in connection with such Change in Control and shall terminate upon
the consummation of such Change in Control. 
  
 F.    The Plan Administrator may at any time provide that one or more options will automatically accelerate upon an Involuntary Termination of the Optionee’s Service within a designated period (not to exceed
eighteen (18) months) following the effective date of any Change in Control in which those options do not otherwise accelerate. Any options so accelerated shall remain exercisable for fully-vested shares until the earlier of (i) the
expiration of the option term or (ii) the expiration of the one (1) year period measured from the effective date of the Involuntary Termination. In addition, the Plan Administrator may at any time provide that one or more of the Corporation’s
repurchase rights shall immediately terminate upon such Involuntary Termination. 
  
 G.    The Plan Administrator may at any time provide that one or more options will automatically accelerate in connection with a Hostile Take-Over. Any such option shall become exercisable,
immediately prior to the effective date of such Hostile Take-Over, for all of the shares of Common Stock at the time subject to that option and may be exercised for any or all of those shares as fully-vested shares of Common Stock. In addition, the
Plan Administrator may at any time provide that one or more of the Corporation’s repurchase rights shall terminate automatically upon the consummation of such Hostile Take-Over. Alternatively, the Plan Administrator may 

  

 6 

 
condition such automatic acceleration and termination upon an Involuntary Termination of the Optionee’s Service within a designated period (not to
exceed eighteen (18) months) following the effective date of such Hostile Take-Over. Each option so accelerated shall remain exercisable for fully-vested shares until the expiration or sooner termination of the option term. 
  
 H.    The portion of any Incentive Option
accelerated in connection with a Change in Control or Hostile Take Over shall remain exercisable as an Incentive Option only to the extent the applicable One Hundred Thousand Dollar ($100,000) limitation is not exceeded. To the extent such dollar
limitation is exceeded, the accelerated portion of such option shall be exercisable as a Non-Statutory Option under the Federal tax laws. 
  
 IV.    STOCK APPRECIATION RIGHTS 
  
 The Plan Administrator may, subject to such conditions as it may determine, grant to selected Optionees stock appreciation rights which will allow the
holders of those rights to elect between the exercise of the underlying option for shares of Common Stock and the surrender of that option in exchange for a distribution from the Corporation in an amount equal to the excess of (a) the Option
Surrender Value of the number of shares for which the option is surrendered over (b) the aggregate exercise price payable for such shares. The distribution may be made in shares of Common Stock valued at Fair Market Value on the option surrender
date, in cash, or partly in shares and partly in cash, as the Plan Administrator shall in its sole discretion deem appropriate. 
  
 ARTICLE THREE 
 STOCK ISSUANCE
PROGRAM 
  
 I.    STOCK ISSUANCE TERMS

  
 Shares of Common Stock may be issued under the Stock
Issuance Program through direct and immediate issuances without any intervening options. Shares of Common Stock may also be issued under the Stock Issuance Program pursuant to share right awards which entitle the recipients to receive those shares
upon the attainment of designated performance goals or Service requirements. Each such award shall be evidenced by one or more documents which comply with the terms specified below. 
  
 A.    Purchase Price. 
  
 1.    The purchase price per share of Common Stock
subject to direct issuance shall be fixed by the Plan Administrator; provided, however, with respect to stock issuances made prior to the Section 12 Registration Date, the purchase price per share shall not be less than eighty-five percent (85%) of
the Fair Market Value per share of Common Stock on the issue date and the purchase price per share of Common Stock issued to a 10% Stockholder shall not be less than one hundred and ten percent (110%) of such Fair Market Value. 
  
 2.    Subject to the provisions of Section II of Article
Six, shares of Common Stock may be issued under the Stock Issuance Program for any of the following items of consideration which the Plan Administrator may deem appropriate in each individual instance: 
  
 (i)  cash or check made payable to the
Corporation, or 
  
 (ii)  past services
rendered to the Corporation (or any Parent or Subsidiary). 
  
 B.    Vesting/Issuance Provisions. 
  
 1.    The Plan Administrator may issue shares of Common Stock which are fully and immediately vested upon issuance or which are to vest in one or more installments over the Participant’s
period of Service or upon attainment of specified performance objectives. Alternatively, the Plan Administrator may issue share right awards which shall entitle the recipient to receive a specified number of vested shares of Common Stock upon the
attainment of one or more performance goals or Service requirements established by the Plan Administrator. However, for stock issuances prior to the Section 12 Registration Date, the Plan Administrator may not impose a 

  

 7 

 
vesting schedule upon any stock issuance effected under the Stock Issuance Program which is more restrictive than twenty percent (20%) per year vesting, with
initial vesting to occur not later than one (1) year after the issuance date. Such limitation shall not apply to any Common Stock issuances made to the officers of the Corporation, non-employee Board members or independent consultants. 

 
 2.    Any new, substituted or additional securities or
other property (including money paid other than as a regular cash dividend) which the Participant may have the right to receive with respect to his or her unvested shares of Common Stock by reason of any stock dividend, stock split,
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 shall be issued subject to (i) the same vesting requirements
applicable to the Participant’s unvested shares of Common Stock and (ii) such escrow arrangements as the Plan Administrator shall deem appropriate. 
  
 3.    The Participant shall have full stockholder rights with respect to the issued shares of Common Stock, whether or not the
Participant’s interest in those shares is vested. Accordingly, the Participant shall have the right to vote such shares and to receive any regular cash dividends paid on such shares. 
  
 4.    Should the Participant cease to remain in Service while holding one or more unvested shares of
Common Stock, or should the performance objectives not be attained with respect to one or more such unvested shares of Common Stock, then those shares shall be immediately surrendered to the Corporation for cancellation, and the Participant shall
have no further stockholder rights with respect to those shares. To the extent the surrendered shares were previously issued to the Participant for consideration paid in cash or cash equivalent (including the Participant’s purchase-money
indebtedness), the Corporation shall repay to the Participant the cash consideration paid for the surrendered shares and shall cancel the unpaid principal balance of any outstanding purchase-money note of the Participant attributable to the
surrendered shares. 
  
 5.    The Plan
Administrator may waive the surrender and cancellation of one or more unvested shares of Common Stock (or other assets attributable thereto) which would otherwise occur upon the cessation of the Participant’s Service or the non-attainment of
the performance objectives applicable to those shares. Such waiver shall result in the immediate vesting of the Participant’s interest in the shares of Common Stock as to which the waiver applies. Such waiver may be effected at any time,
whether before or after the Participant’s cessation of Service or the attainment or non-attainment of the applicable performance objectives. 
  
 6.    Outstanding share right awards shall automatically terminate, and no shares of Common Stock shall actually be issued in
satisfaction of those awards, if the performance goals or Service requirements established for such awards are not attained. The Plan Administrator, however, shall have the authority to issue shares of Common Stock in satisfaction of one or more
outstanding share right awards as to which the designated performance goals or Service requirements are not attained. 
  
 II.    CHANGE IN CONTROL/HOSTILE TAKE-OVER 
  
 A.    All of the Corporation’s outstanding repurchase rights shall terminate automatically, and all the shares of Common
Stock subject to those terminated rights shall immediately vest in full, in the event of any Change in Control, except to the extent (i) those repurchase rights are assigned to the successor corporation (or parent thereof) or otherwise continue in
full force and effect pursuant to the terms of the Change in Control or (ii) such accelerated vesting is precluded by other limitations imposed by the Plan Administrator at the time the repurchase right is issued. 
  
 B.    The Plan Administrator may at any time
provide for the automatic termination of one or more of those outstanding repurchase rights and the immediate vesting of the shares of Common Stock subject to those terminated rights upon (i) a Change in Control or Hostile Take-Over or (ii) an
Involuntary Termination of the Participant’s Service within a designated period (not to exceed eighteen (18) months) following the effective date 

  

 8 

 
of any Change in Control or Hostile Take-Over in which those repurchase rights are assigned to the successor corporation (or parent thereof) or otherwise
continue in full force and effect. 
  
 III.    SHARE
ESCROW/LEGENDS 
  
 Unvested shares may, in the Plan
Administrator’s discretion, be held in escrow by the Corporation until the Participant’s interest in such shares vests or may be issued directly to the Participant with restrictive legends on the certificates evidencing those unvested
shares. 
  
 ARTICLE FOUR 
 AUTOMATIC OPTION GRANT PROGRAM 
  
 I.    OPTION TERMS 
  
 A.    Grant Dates.    Options shall be made on the dates specified below:

  
 1.    Each individual who is first
elected or appointed as a non-employee Board member at any time after the Underwriting Date shall automatically be granted, on the date of such initial election or appointment, a Non-Statutory Option to purchase Fifty Thousand (50,000) shares of
Common Stock, provided that individual has not previously been in the employ of the Corporation (or any Parent or Subsidiary). 
  
 2.    On the date of each Annual Stockholders Meeting beginning with the 2001 Annual Stockholder Meeting, each individual who has
served as a non-employee Board member since the date of the Annual Stockholders Meeting in the immediately preceding year shall automatically be granted a Non-Statutory Option to purchase Fifteen Thousand (15,000) shares of Common Stock. 

 
 B.    Exercise
Price. 
  
 1.    The exercise
price per share shall be equal to one hundred percent (100%) of the Fair Market Value per share of Common Stock on the option grant date. 
  
 2.    The exercise price shall be payable in one or more of the alternative forms authorized under the Discretionary Option Grant
Program. Except to the extent the sale and remittance procedure specified thereunder is utilized, payment of the exercise price for the purchased shares must be made on the Exercise Date. 
  
 C.    Option Term.    Each option shall have a
term of ten (10) years measured from the option grant date. 
  
 D.    Exercise and Vesting of Options.    Each option shall be immediately exercisable for any or all of the option shares. However, any shares purchased under the
initial 50,000 share option shall be subject to repurchase by the Corporation, at the exercise price paid per share, upon the Optionee’s cessation of Board service prior to vesting in those shares. Each initial 50,000-share option shall vest,
and the Corporation’s repurchase right shall lapse, in a series of four (4) successive equal annual installments over the Optionee’s period of continued service as a Board member, with the first such installment to vest upon the
Optionee’s completion of one (1) year of Board service measured from the option grant date. Each annual 15,000-share option shall be fully vested at the time of grant. 
  
 E.    Cessation of Board Service.    The
following provisions shall govern the exercise of any options outstanding at the time of the Optionee’s cessation of Board service: 
  
 (i)  Any option outstanding at the time of the Optionee’s cessation of Board service for any reason shall remain
exercisable for a twelve (12)-month period following the date of such cessation of Board service, but in no event shall such option be exercisable after the expiration of the option term. 
  
 (ii)  Any option exercisable in whole or in part
by the Optionee at the time of death may be subsequently exercised by his or her Beneficiary. 
  

 9 

 (iii) Following the Optionee’s cessation of Board service, the option may not be
exercised in the aggregate for more than the number of shares for which the option was exercisable on the date of such cessation of Board service. Upon the expiration of the applicable exercise period or (if earlier) upon the expiration of the
option term, the option shall terminate and cease to be outstanding for any vested shares for which the option has not been exercised. However, the option shall, immediately upon the Optionee’s cessation of Board service, terminate and cease to
be outstanding for any and all shares for which the option is not otherwise at that time exercisable. 
  
 (iv) However, should the Optionee cease to serve as a Board member by reason of death or Permanent Disability, then all shares at the time
subject to the option shall immediately vest so that such option may, during the twelve (12)-month exercise period following such cessation of Board service, be exercised for all or any portion of those shares as fully-vested shares of Common Stock.

  
 II.    CHANGE IN CONTROL/HOSTILE TAKE-OVER

  
 A.    In the event of any
Change in Control or Hostile Take-Over, the shares of Common Stock at the time subject to each outstanding option but not otherwise vested shall automatically vest in full so that each such option may, immediately prior to the effective date of such
Change in Control or Hostile Take-Over, became fully exercisable for all of the shares of Common Stock at the time subject to such option and maybe exercised for all or any of those shares as fully-vested shares of Common Stock. Each such option
accelerated in connection with a Change in Control shall terminate upon the Change in Control, except to the extent assumed by the successor corporation (or parent thereof) or otherwise continued in full force and effect pursuant to the terms of the
Change in Control. Each such option accelerated in connection with a Hostile Take-Over shall remain exercisable until the expiration or sooner termination of the option term. 
  
 B.    All outstanding repurchase rights shall automatically terminate and the shares of Common
Stock subject to those terminated rights shall immediately vest in full, in the event of any Change in Control or Hostile Take-Over. 
  
 C.    Upon the occurrence of a Hostile Take-Over, the Optionee shall have a thirty (30)-day period in which to surrender to the
Corporation each of his or her outstanding options. The Optionee shall in return be entitled to a cash distribution from the Corporation in an amount equal to the excess of (i) the Option Surrender Value of the shares of Common Stock at the time
subject to each surrendered option (whether or not the option is otherwise at the time exercisable for those shares) over (ii) the aggregate exercise price payable for such shares. Such cash distribution shall be paid within five (5) days following
the surrender of the option to the Corporation. 
  
 D.    Each option which is assumed in connection with a Change in Control shall be appropriately adjusted to apply to the number and class of securities which would have been issuable to the Optionee in
consummation of such Change in Control had the option been exercised immediately prior to such Change in Control. Appropriate adjustments shall also be made to the exercise price payable per share under each outstanding option, provided the
aggregate exercise price payable for such securities shall remain the same. 
  
 III.    REMAINING TERMS 
  
 The remaining terms of each option granted under the Automatic Option Grant Program shall be the same as the terms in effect for options made under the Discretionary Option Grant Program. 
  

 10 

 ARTICLE FIVE 
 DIRECTOR FEE OPTION GRANT PROGRAM 
  
 I.    OPTION GRANTS 
  
 The
Board may implement the Director Fee Option Grant Program as of the first day of any calendar year. Upon such implementation of the Program, each non-employee Board member may elect to apply all or any portion of the annual retainer fee otherwise
payable in cash for his or her service on the Board or any Board committee to the acquisition of a special option grant under this Director Fee Option Grant Program. Such election must be filed with the Corporation’s Secretary prior to the
first day of the calendar year for which the election is to be in effect, except as provided below. Each non-employee Board member who files such a timely election with respect to the annual retainer fee shall automatically be granted an option
under this Director Fee Option Grant Program on the first trading day in January in the calendar year for which that fee would otherwise be payable; provided, however, that elections to receive option grants with respect to fees payable for 2004
must be filed with the Corporation’s Secretary prior to April 1, 2004, and the options in respect of such elections will be granted on April 1, 2004. For purposes of this Program, an “annual retainer fee” means the amount to which a
non-employee director will be entitled to receive for serving as a director in a relevant calendar year, including service on any Board committee, but shall not include reimbursement of expenses, fees determined on a per-meeting attended basis, or
fees with respect to any other services provided or to be provided to the Corporation. 
  
 II.    OPTION TERMS 
  
 Each
option shall be a Non-Statutory Option governed by the terms and conditions specified below. 
  
 A.    Exercise Price. 
  
 1.    The exercise price per share shall be the Fair Market Value per share of Common Stock on the option grant date. 
  
 2.    The exercise price shall become immediately due
upon exercise of the option and shall be payable in one or more of the alternative forms authorized under the Discretionary Option Grant Program. Except to the extent the sale and remittance procedure specified thereunder is utilized, payment of the
exercise price for the purchased shares must be made on the Exercise Date. 
  
 B.    Number of Option Shares.    The number of shares of Common Stock subject to the option shall be an amount necessary to make such
option equal in value, using a modified Black-Scholes option valuation model, to that the portion of the annual retainer fee that the non-employee director elected to receive in the form of an option. The value of the option will be calculated by
assuming that the value of an option to purchase one share of Common Stock equals the product of (i) a fraction determined by dividing one (1) by the Multiplier (as defined below) and (ii) the fair Market Value of a share of Common Stock on the
option grant date. 
  
 The number of shares represented by an
option granted pursuant to the Director Fee Option Grant Program shall be determined by (a) dividing the amount of the annual retainer that the non-employee director elects to receive in the form of options by the Fair Market Value of a share of
Common Stock on the date of grant, and (b) multiplying the quotient so obtained by a multiplier determined using a modified Black-Scholes option valuation method (the “Multiplier”). The Board or the Plan Administrator shall determine the
Multiplier prior to the beginning of a relevant calendar year by considering the following factors: (i) the Fair Market Value of the Common Stock on the date the Multiplier is determined; (ii) the average length of time the stock options of the
Corporation are held by optionees prior to exercise; (iii) the risk-free rate of return based on the term determined in (ii) above and U.S. government securities rates; (iv) the annual dividend yield for the Common stock, if any; and (v) the
volatility of the Common Stock over the previous two-year period. The number of shares to be subject to the option shall be equal to the largest number of whole shares determined as follows: 
  

			
	 Amount of Retainer

	  	X Multiplier = Number of Shares
	Fair Market Value on Grant Date	  

  

 11 

 C.    Exercise and Term of
Options.    The option shall become exercisable in a series of twelve (12) successive equal monthly installments upon the Optionee’s completion of each month of Board service during the calendar year in which
the option is granted; provided, however, that the number of monthly vesting installments for options granted for 2004 shall be nine (9). Each option shall have a maximum term of ten (10) years measured from the option grant date. 
  
 D.    Cessation of Board
Service.    Should the Optionee cease Board service for any reason (other than death or Permanent Disability) while holding one or more options, then each such option shall remain exercisable, for any or all of the
shares for which the option is exercisable at the time of such cessation of Board service, until the earlier of (i) the expiration of the ten (10)-year option term or (ii) the expiration of the three (3)-year period measured from the date of
such cessation of Board service. However, each option held by the Optionee at the time of such cessation of Board service shall immediately terminate and cease to remain outstanding with respect to any and all shares of Common Stock for which the
option is not otherwise at that time exercisable. 
  
 E.    Death or Permanent Disability.    Should the Optionee’s service as a Board member cease by reason of death or Permanent Disability, then each option held
by such Optionee shall immediately become exercisable for all the shares of Common Stock at the time subject to that option, and the option may be exercised for any or all of those shares as fully-vested shares until the earlier of (i) the
expiration of the ten (10)-year option term or (ii) the expiration of the three (3)-year period measured from the date of such cessation of Board service. 
  
 Should the Optionee die after cessation of Board service but while holding one or more options, then each such option may be exercised, for any or all of
the shares for which the option is exercisable at the time of the Optionee’s cessation of Board service (less any shares subsequently purchased by Optionee prior to death), by the Optionee’s Beneficiary. Such right of exercise shall lapse,
and the option shall terminate, upon the earlier of (i) the expiration of the ten (10)-year option term or (ii) the three (3)-year period measured from the date of the Optionee’s cessation of Board service. 
  
 III.    CHANGE IN CONTROL/HOSTILE TAKE-OVER 
  
 A.    In the event of any Change in Control or
Hostile Take-Over while the Optionee remains in Board service, each outstanding option held by such Optionee shall automatically accelerate so that each such option shall, immediately prior to the effective date of the Change in Control or Hostile
Take-Over, become fully exercisable with respect to the total number of shares of Common Stock at the time subject to such option and may be exercised for any or all of those shares as fully-vested shares of Common Stock. Each such option
accelerated in connection with a Change in Control shall terminate upon the Change in Control, except to the extent assumed by the successor corporation (or parent thereof) or otherwise expressly continued in full force and effect pursuant to the

shares of Common Stock at the time subject to each surrendered option (whether or not the Optionee is otherwise at the time vested in those shares) over (ii) the aggregate exercise price payable for such shares. Such cash distribution shall be paid
within five (5) days following the surrender of the option to the Corporation.

 I.    NO IMPAIRMENT OF AUTHORITY 
  
 Outstanding awards shall in no 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. 
  
 II.    FINANCING

  
 The Plan Administrator may permit any Optionee or

installments. The terms of any such promissory note (including the interest rate and the terms of repayment) shall be established by the Plan Administrator in its sole discretion. In no event may the maximum credit available to the Optionee or
Participant 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 or the Participant in
connection with the option exercise or share purchase.

Common Stock in satisfaction of all or part of the Withholding Taxes incurred by such holders in connection with the exercise of their options or the vesting of their shares. Such right may be provided to any such holder in either or both of the
following formats: 
  
 Stock
Withholding:  The election to have the Corporation withhold, from the shares of Common Stock otherwise issuable upon the exercise of such Non-Statutory Option or the vesting of such shares, a portion of those shares with an aggregate
Fair Market Value equal to the percentage of the Withholding Taxes (not to exceed one hundred percent (100%)) designated by the holder. 
  
 Stock Delivery:  The election to deliver to the Corporation, at the time the Non-Statutory Option is exercised or the
shares vest, one or more shares of Common Stock previously acquired by such holder (other than in connection with the option exercise or share vesting triggering the Withholding Taxes) with an aggregate Fair Market Value equal to the percentage of
the Taxes (not to exceed one hundred percent (100%)) designated by the holder. 
  
 IV.    FINANCIAL REPORTS

 V.    EFFECTIVE DATE AND TERM OF THE PLAN 
  
 A.    The Plan shall become effective immediately
upon the Plan Effective Date. However, the Director Fee Option Grant Program shall not be implemented until such time as the Primary Committee or the Board may deem appropriate. Options may be granted under the Discretionary Option Grant Program at
any time on or after the Plan Effective Date. However, no options granted under the Plan may be exercised, and no shares shall be issued under the Plan, until the Plan is approved by the Corporation’s stockholders. If such stockholder approval
is not obtained within twelve (12) months after the Plan Effective Date, then all options previously granted under this Plan shall terminate and cease to be outstanding, and no further options shall be granted and no shares shall be issued under the
Plan. 
  
 B.    The Plan shall serve as
the successor to the Predecessor Plan, and no further options or direct stock issuances shall be made under the Predecessor Plan after the Section 12 Registration Date. All options outstanding under the Predecessor Plan on the Section 12
Registration Date shall be incorporated into the Plan at that time and shall be treated as outstanding options under the Plan. However, each outstanding option so incorporated shall continue to be governed solely by the terms of the documents
evidencing such option, and no provision of the Plan shall be deemed to affect or otherwise modify the rights or obligations of the holders of such incorporated options with respect to their acquisition of shares of Common Stock. 
  
 C.    One or more provisions of the Plan,
including (without limitation) the option/vesting acceleration provisions of Article Two relating to Changes in Control, may, in the Plan Administrator’s discretion, be extended to one or more options incorporated from the Predecessor Plan
which do not otherwise contain such provisions. 
  
 D.    The Plan shall terminate upon the earliest of (i) June 8, 2009, (ii) the date on which all shares available for issuance under the Plan shall have been issued as fully-vested shares or (iii) the
termination of all outstanding options in connection with a Change in Control. Upon such plan termination, all outstanding options and unvested stock issuances shall thereafter continue to have force and effect in accordance with the provisions of
the documents evidencing such grants or issuances. 
  
 VI.    AMENDMENT OF THE PLAN 
  
 A.    The Board shall have complete and exclusive power and authority to amend or modify the Plan in any or all respects. However, no such amendment or modification shall adversely affect the rights and
obligations with respect to stock options or unvested stock issuances at the time outstanding under the Plan unless the Optionee or the Participant consents to such amendment or modification. In addition, certain amendments may require stockholder
approval pursuant to applicable laws or regulations. 
  
 B.    Options to purchase shares of Common Stock may be granted under the Discretionary Option Grant Program and shares of Common Stock may be issued under the Stock Issuance Program that are in each instance in
excess of the number of shares then available for issuance under the Plan, provided any excess shares actually issued under those programs shall be held in escrow until there is obtained stockholder approval of an amendment sufficiently increasing
the number of shares of Common Stock available for issuance under the Plan. If such stockholder approval is not obtained within twelve (12) months after the date the first such excess issuances are made, then (i) any unexercised options granted on
the basis of such excess shares shall terminate and cease to be outstanding and (ii) the Corporation shall promptly refund to the Optionees and the Participants the exercise or purchase price paid for any excess shares issued under the Plan and held
in escrow, together with interest (at the applicable Short Term Federal Rate) for the period the shares were held in escrow, and such shares shall thereupon be automatically cancelled and cease to be outstanding.

 VII.    USE OF PROCEEDS 
  
 Any cash proceeds received by the Corporation from the sale of shares of Common Stock under the Plan shall be used for
general corporate purposes. 
  
 VIII.    REGULATORY
APPROVALS 
  
 A.    The
implementation of the Plan, the granting of any stock option under the Plan and the issuance of any shares of Common Stock (i) upon the exercise of any granted option or (ii) under the Stock Issuance Program shall be subject to the
Corporation’s procurement of all approvals and permits required by regulatory authorities having jurisdiction over the Plan, the stock options granted under it and the shares of Common Stock issued pursuant to it. 
  
 B.    No shares of Common Stock or other assets
shall be issued or delivered under the Plan unless and until there shall have been compliance with all applicable requirements of Federal and state securities laws, including the filing and effectiveness of the Form S-8 registration statement for
the shares of Common Stock issuable under the Plan, and all applicable listing requirements of any stock exchange (or the Nasdaq National Market, if applicable) on which Common Stock is then listed for trading. 
  
 IX.    NO EMPLOYMENT/SERVICE RIGHTS 
  
 Nothing in the Plan shall confer upon the Optionee or the Participant any
right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Corporation (or any Parent or Subsidiary employing or retaining such person) or of the Optionee or the Participant,
which rights are hereby expressly reserved by each, to terminate such person’s Service at any time for any reason, with or without cause.
