MICROMUSE INC.

1997 STOCK OPTION/STOCK ISSUANCE PLAN



(As amended and restated June 30, 1999)



ARTICLE I



GENERAL
PROVISIONS



I. PURPOSE OF THE PLAN



This 1997 Stock Option/Stock Issuance Plan is intended to promote the
interests of Micromuse Inc., a Delaware 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 two 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, and



(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 to the Corporation (or any Parent or Subsidiary).



B. The provisions of Articles One and Four shall apply to all equity programs under the Plan and shall accordingly govern the interests of all persons
under the Plan.



III. ADMINISTRATION OF THE PLAN



A. Prior to the Section 12(g) Registration Date, the
Discretionary Option Grant and Stock Issuance Programs shall be administered by the Board.



B. Beginning with the Section 12(g) Registration Date, the Primary Committee shall have sole and exclusive authority to administer the Discretionary Option Grant and Stock Issuance Programs with respect to Section 16
Insiders. 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.



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. Each Plan
Administrator shall, within the scope of its administrative functions under the Plan, have full power and authority to establish such rules and regulations as it may deem appropriate for proper administration of the Discretionary Option Grant and
Stock Issuance Programs and to make such determinations under, and issue such interpretations of, the provisions of such programs and any outstanding options or stock issuances thereunder as it may deem necessary or advisable. Decisions of the Plan
Administrator within the scope of its administrative functions under the Plan shall be final and binding on all parties who have an interest in the Discretionary Option Grant or Stock Issuance Program under its jurisdiction or any option or stock
issuance thereunder.



E. 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 option grants 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. Each Plan Administrator shall, within the scope of its administrative jurisdiction under the Plan, have full authority (subject to the provisions of the Plan) to determine, (i) with respect to the option grants
under the Discretionary Option Grant Program, which eligible persons are to receive option grants, the time or times when such option grants are to be made, the number of shares to be covered by each such grant, the status of the granted option as
either an Incentive Option or a Non-Statutory Option, the time or times at which each option is to become exercisable, the vesting schedule (if any) applicable to the option shares and the maximum term for which the option is to remain outstanding
and (ii) with respect to stock



2



---

issuances under the Stock Issuance Program, which eligible persons are to receive stock issuances, the time or times when
such issuances are to be made, the number of shares to be issued to each Participant, the vesting schedule (if any) applicable to the issued shares and the consideration to be paid for such shares.



C. The Plan Administrator shall have the absolute discretion either to grant
options in accordance with the Discretionary Option Grant Program or to effect stock issuances in accordance with the Stock Issuance Program.



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 which may be issued over the term of the Plan shall not exceed three million three hundred twelve thousand (3,312,000) shares.



B. The number of shares of Common Stock available for issuance under the Plan
shall automatically increase on October 1 of each fiscal year during the term of the Plan, beginning with October 1, 1999, by an amount equal to the lesser of (i) one million (1,000,000) shares of Common Stock (subject to adjustment for stock
splits) or (ii) five percent (5%) of the total number of shares of Common Stock then outstanding.



C. No one person participating in the Plan may receive options, separately exercisable stock appreciation rights and direct stock issuances for more than
500,000 shares of Common Stock per calendar year beginning with the 1997 calendar year.



D. Shares of Common Stock subject to outstanding options shall be available for subsequent issuance under the Plan to the extent (i) the options expire or terminate for any reason prior to exercise in full or (ii) the
options are cancelled in accordance with the cancellation-regrant provisions of Section IV of Article Two. Unvested shares issued under the Plan and subsequently repurchased by the Corporation at the original 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 option grants
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.



E. 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



3



---

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 for which any one person may be granted options, separately exercisable stock appreciation rights and direct stock issuances per calendar year and (iii) the number and/or class of securities and
the exercise price per share in effect under each outstanding option in order to prevent the dilution or enlargement of benefits thereunder. The adjustments determined by the Plan Administrator shall be final, binding and conclusive.

ARTICLE II



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 in accordance with the following provisions:



(i) To the extent required by applicable tax or securities laws, 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; otherwise, the exercise price per share shall be determined in the sole discretion of the Plan
Administrator.



(ii) To the extent required by applicable tax
or securities laws, if the person to whom the 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; otherwise, the exercise price per share shall be determined in the sole discretion of the Plan Administrator.



2. The exercise price shall become immediately due upon exercise of the option and shall, subject to the provisions of Section I of Article Four 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(g) of the 1934 Act at the time the option is exercised, then the exercise price may also be paid as
follows:



(i) in 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



(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 written instructions to (a) 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 (b) the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale.



5



---

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 or, if required by the United Kingdom or Australian tax or securities laws, a term in excess of seven (7) years.



C. Effect of Termination of Service.



1. The following provisions shall govern the exercise of any options held
by the Optionee at the time of cessation of Service or death:



(i) Should the Optionee cease to remain in Service for any reason other than death, Disability or Misconduct, then the Optionee shall have a period of three (3) months following the date of such cessation of Service during which to exercise
each outstanding option held by such Optionee.



(ii) Should
Optionees Service terminate by reason of Disability, then the Optionee shall have a period of twelve (12) months following the date of such cessation of Service during which to exercise each outstanding option held by such Optionee.



(iii) If the Optionee dies while holding an outstanding
option, then the personal representative of his or her estate or the person or persons to whom the option is transferred pursuant to the Optionees will or the laws of inheritance shall have a twelve (12)-month period following the date of the
Optionees death to exercise such option.



(iv) Under no
circumstances, however, shall any such option be exercisable after the specified expiration of the option term.



(v) 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.



(vi) Should the
Optionees Service be terminated for Misconduct, then all outstanding options held by the Optionee shall terminate immediately and cease to be outstanding.



2. The Plan Administrator shall have the discretion, exercisable either at the time an option is granted or at any time while the option remains
outstanding, to:



6



---

(i) extend the period of time for which the option is to remain exercisable following the
Optionees cessation of Service from the period otherwise in effect for that option to such greater period of time as the Plan Administrator shall deem appropriate, but in no event beyond the expiration of the option term, and/or



(ii) permit the option to be exercised, during the applicable post-Service
exercise period, not only with respect to the number of vested shares of Common Stock for which such option is exercisable at the time of the Optionees cessation of Service but also with respect to one or more additional installments in which
the Optionee would have vested under the option 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.



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. The Plan Administrator may not impose a vesting schedule upon the option grant or any 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 such time as the Common Stock is first registered under Section 12(g) of the 1934 Act, the Corporation shall
have the right of first refusal with respect to any proposed disposition by the Optionee (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 set forth in the document evidencing such right.



G. Limited Transferability of Options. During the lifetime of the Optionee, the option shall be exercisable only by the Optionee and shall not be assignable or transferable other than by will or by the
laws of descent and distribution following the Optionees death. The foregoing notwithstanding, the Plan Administrator shall have the discretion, exercisable either at the time the option is granted or at any time while the option remains
outstanding, to provide for the limited or unlimited transferability of a Non-Statutory Option.



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 Four



7



---

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 (1) 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 option term shall not exceed five (5) years measured from the option grant date.



III. CORPORATE TRANSACTION/CHANGE IN CONTROL



A. In the event of any Corporate Transaction, each outstanding option shall automatically accelerate so that each such option shall, immediately prior to
the effective date of the Corporate Transaction, become fully exercisable for all of the 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. However,
an outstanding option shall not so accelerate if and to the extent: (i) such 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), (ii) such option is to be replaced with a cash incentive program of the successor corporation which preserves the spread existing on the unvested option
shares at the time of the Corporate Transaction and provides for subsequent payout in accordance with the same vesting schedule applicable to such option or (iii) the acceleration of such option is subject to other limitations imposed by the Plan
Administrator at the time of the option grant. The determination of option comparability under clause (i) above shall be made by the Plan Administrator, and its determination shall be final, binding and conclusive.



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 Corporate Transaction, except to the extent: (i) those repurchase rights are to be assigned to the successor corporation (or parent
thereof) in connection with such Corporate



8



---

Transaction or (ii) such accelerated vesting is precluded by other limitations imposed by the Plan Administrator at the
time the repurchase right is issued.



C. Notwithstanding
Section III.A. and Section III.B. of this Article Two, the Plan Administrator shall have the discretion, exercisable either at the time the option is granted or at any time while the option remains outstanding, to provide for the automatic
acceleration of one or more outstanding options (and the automatic termination of one or more outstanding repurchase rights with the immediate vesting of the shares of Common Stock subject to those rights) upon the occurrence of a Corporate
Transaction, whether or not those options are to be assumed or replaced (or those repurchase rights are to be assigned) in the Corporate Transaction. The Plan Administrator shall also have the discretion to grant options which do not accelerate
whether or not such options are assumed (and to provide for repurchase rights that do not terminate whether or not such rights are assigned) in connection with a Corporate Transaction.



D. Immediately following the consummation of the Corporate Transaction, all outstanding options shall terminate and cease to
be outstanding, except to the extent assumed by the successor corporation (or parent thereof).



E. Each option which is assumed in connection with a Corporate Transaction shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had the option been exercised immediately prior to such Corporate Transaction. Appropriate adjustments shall also be made to (i) the number and class of securities available
for issuance under the Plan following the consummation of such Corporate Transaction, (ii) the exercise price payable per share under each outstanding option, provided the aggregate exercise price payable for such securities shall remain the
same and (iii) the maximum number of securities and/or class of securities for which any one person may be granted stock options, separately exercisable stock appreciation rights and direct stock issuances under the Plan.



F. The Plan Administrator shall have the discretion, exercisable at the time
the option is granted or at any time while the option remains outstanding, to provide for the automatic acceleration of any options which are assumed or replaced in a Corporate Transaction and do not otherwise accelerate at that time (and the
termination of any of the Corporations outstanding repurchase rights which do not otherwise terminate at the time of the Corporate Transaction) in the event the Optionees Service should subsequently terminate by reason of an Involuntary
Termination within eighteen (18) months following the effective date of such Corporate Transaction. 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.



G. The Plan Administrator shall have the discretion, exercisable either at the time the option is granted or at any time while the option remains
outstanding, to (i) provide for the automatic acceleration of one or more outstanding options (and the automatic termination of one or more outstanding repurchase rights with the immediate vesting of the shares of Common Stock subject to those
rights) upon the occurrence of a Change in Control or (ii) condition any



9



---

such option acceleration (and the termination of any outstanding repurchase rights) upon the subsequent Involuntary
Termination of the Optionees Service within a specified period (not to exceed eighteen (18) months) following the effective date of such Change in Control. Any options accelerated in connection with a Change in Control shall remain fully
exercisable until the expiration or sooner termination of the option term.



H. The portion of any Incentive Option accelerated in connection with a Corporate Transaction or Change in Control 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.



I. The grant of options under the Discretionary Option Grant Program 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.



IV. CANCELLATION AND REGRANT OF OPTIONS



The Plan Administrator shall have the authority to effect, at any time and
from time to time, with the consent of the affected option holders, the cancellation of any or all outstanding options under the Discretionary Option Grant Program 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 grant date.



V. STOCK APPRECIATION RIGHTS



A. The Plan Administrator shall have full power and authority to grant to selected Optionees tandem stock appreciation rights and/or limited stock
appreciation rights.



B. The following terms shall govern the

ARTICLE III



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 option grants. Each
such stock issuance shall be evidenced by a Stock Issuance Agreement which complies with the terms specified below.



A. Purchase Price.



1. The purchase price per share shall be fixed by the Plan Administrator, but shall not be less than eighty-five percent (85%) of the Fair Market Value
per share of Common Stock on the issue date. However, 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 I of Article Four, 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 Provisions.



1. Shares of Common Stock issued under the Stock Issuance Program may, in
the discretion of the Plan Administrator, be fully and immediately vested upon issuance or may vest in one or more installments over the Participants period of Service or upon attainment of specified performance objectives. However, the Plan
Administrator may not impose a 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 the Participants 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



12



---

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 any
shares of Common Stock issued to the Participant under the Stock Issuance Program, 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 issued under the Stock Issuance Program 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 in its discretion 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.



II. CORPORATE
TRANSACTION/CHANGE IN CONTROL



A. All of the
Corporations outstanding repurchase rights under the Stock Issuance Program 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 Corporate
Transaction, except to the extent (i) those repurchase rights are assigned to the successor corporation (or parent thereof) in connection with such Corporate Transaction or (ii) such accelerated vesting is precluded by other limitations imposed in
the Stock Issuance Agreement.



B. Notwithstanding Section II.A.
of this Article Three, the Plan Administrator shall have the discretionary authority, exercisable either at the time the unvested shares are issued or any time while the Corporations repurchase rights remain outstanding under the Stock
Issuance Program, to provide that those rights shall automatically terminate in whole or in part, and the shares of Common Stock subject to those terminated rights shall immediately vest, in the event of a Corporate Transaction, whether or not those
repurchase rights are to be assigned to the successor corporation (or its parent) in connection with such Corporate Transaction. The Plan



13



---

Administrator shall also have the discretion to provide for repurchase rights with terms different from those in effect under this Section II in connection
with a Corporate Transaction.



C. The Plan Administrator shall
have the discretion, exercisable either at the time the unvested shares are issued or at any time while the Corporations repurchase rights remain outstanding, to provide that any repurchase rights that are assigned in the Corporate Transaction
shall automatically terminate, and the shares of Common Stock subject to those terminated rights shall immediately vest in full, in the event the Participants Service should subsequently terminate by reason of an Involuntary Termination within
eighteen (18) months following the effective date of such Corporate Transaction.



D. The Plan Administrator shall have the discretion, exercisable either at the time the unvested shares are issued or at any time while the Corporations repurchase right remains outstanding, to (i) provide for
the automatic termination of one or more outstanding repurchase rights and the immediate vesting of the shares of Common Stock subject to those rights upon the occurrence of a Change in Control or (ii) condition any such accelerated vesting upon the
subsequent Involuntary Termination of the Participants Service within a specified period (not to exceed eighteen (18) months) following the effective date of such Change in Control.



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.



14

ARTICLE IV



MISCELLANEOUS



I. FINANCING



A. The Plan Administrator may permit any Optionee or Participant to pay the option exercise price under the Discretionary Option Grant Program or the
purchase price for shares issued under the Stock Issuance Program by delivering a full-recourse, interest bearing promissory note payable in one or more 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 all events, the maximum credit available to the Optionee or Participant 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 or the Participant in connection with the option exercise or share purchase.



B. The Plan Administrator 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 Plan Administrator may deem appropriate.



II. TAX WITHHOLDING



A. The Corporations obligation to deliver shares of Common Stock upon the exercise of options or upon the issuance or vesting of such shares under
the Plan shall be subject to the satisfaction of all applicable Federal, state and local income and employment tax withholding requirements and any United Kingdom or Australian income or employment tax withholding requirements.



B. The Plan Administrator may, in its discretion, provide any or all holders
of Non-Statutory Options or unvested shares of Common Stock under the Plan with the right to use shares of Common Stock in satisfaction of all or part of the 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:



(i) 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 Taxes (not to exceed one hundred percent (100%)) designated by the holder.



(ii) 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 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.



III. EFFECTIVE DATE AND
TERM OF THE PLAN



A. The Plan shall become effective on
the Plan Effective Date. Options may be granted 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.

options in connection with a Corporate Transaction. Upon such Plan termination, all outstanding options and unvested stock issuances shall continue to have force and effect in accordance with the provisions of the documents evidencing such options
or issuances.



IV. 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 any rights and obligations with respect to options, stock appreciation rights 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, amendments to the Plan shall be subject to approval of the Corporations stockholders to the extent required by 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 are 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 grants or 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

of all approvals and permits required by regulatory authorities having jurisdiction over the Plan, the options and stock appreciation rights granted under it and the shares of Common Stock issued pursuant to it.

which Common Stock is then listed for trading.



VII. 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.



VIII. FINANCIAL REPORTS
