1997 STOCK OPTION/STOCK ISSUANCE PLAN

(As amended and restated October 1, 2003)

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

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 (3,312,600) 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

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.

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:

(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 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 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

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 grant and exercise of tandem stock appreciation rights:

(i) One or more Optionees may be granted the right, exercisable upon such terms as the Plan Administrator may establish, 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 Fair Market Value (on the option surrender date) of the number of shares in which the Optionee is at the time vested under the surrendered option (or surrendered portion thereof) over (b) the aggregate exercise price payable for such shares.

(ii) No such option surrender shall be effective unless it is approved by the Plan Administrator. If the surrender is so approved, then the distribution to which the Optionee shall be entitled 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.

(iii) If the surrender of an option is rejected by the Plan Administrator, then the Optionee shall retain whatever rights the Optionee had under the surrendered option (or surrendered portion thereof) on the option surrender date and may exercise such rights at any time prior to the later of (a) five (5) business days after the receipt of the rejection notice or (b) the last day on which the option is otherwise exercisable in accordance with the terms of the documents evidencing such option, but in no event may such rights be exercised more than ten (10) years after the option grant date.

C. The following terms shall govern the grant and exercise of limited stock appreciation rights:

(i) One or more Section 16 Insiders may be granted limited stock appreciation rights with respect to their outstanding options.

(ii) Upon the occurrence of a Hostile Take-Over, each such individual holding one or more options with such a limited stock appreciation right shall have the unconditional right (exercisable for a thirty (30)-day period following such Hostile Take-Over) to surrender each such option to the Corporation, to the extent the option is at the time exercisable for vested shares of Common Stock. In return for the surrendered option, the Optionee shall receive a cash distribution from the Corporation in an amount equal to the excess of (a) the Take-Over Price of the shares of Common Stock which are at the time vested under each surrendered option (or surrendered portion thereof) over (b) the aggregate exercise price payable for such shares. Such cash distribution shall be paid within five (5) days following the option surrender date.

(iii) Neither the approval of the Plan Administrator nor the consent of the Board shall be required in connection with such option surrender and cash distribution.

(iv) The balance of the option (if any) shall continue in full force and effect in accordance with the documents evidencing such option.

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 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 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.

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.

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.

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 period the shares were held in escrow, and such shares shall thereupon be automatically cancelled and cease to be outstanding.

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.

AMENDMENT 1

1997 STOCK INCENTIVE PLAN FOR FRENCH EMPLOYEES

1. Introduction

The Board of Directors of Micromuse Inc. (the “Company”) has established the Micromuse Inc. 1997 Stock Option/Stock Issuance Plan (the “U.S. Plan”) for the benefit of certain employees of the Company, its parent and subsidiary companies, including its French subsidiaries, (the “Subsidiary” or the “Subsidiaries”) of which the Company holds directly or indirectly at least 10% of the capital. Article I Section III of the U.S. Plan specifically authorizes the Plan Administrator to establish rules applicable to options granted under the U.S. Plan (including those in France) (the “ Board”) to adopt procedures and forms relating to the U.S. Plan as it deems advisable. The Plan Administrator has determined that it is advisable to establish a sub-plan of the U.S. Plan for France for the purpose of permitting such Options, to qualify for French favorable local tax and social security treatment. The Plan Administrator, therefore, intends to establish a sub-plan of the U.S. Plan for the purpose of granting options which qualify for the favorable tax and social security treatment in France applicable to Options granted under Sections L 225-177 to L 225-186 of the French Commercial Code to qualifying employees who are resident in France for French tax purposes (the “French Optionees”). The terms of the U.S. Plan, effective as of March 7, 1997, and as set out in Appendix 1 hereto, shall, subject to the modifications in the following rules, constitute the Micromuse Inc. 1997 Stock Incentive Plan for French Employees (the “French Plan”).

Under the French Plan, the qualifying employees will be granted only Stock Options as defined in Section 2 hereunder. The provisions of Article I Section II(ii), Article II Section V, and Article III of the U.S. Plan permitting the grant of stock appreciation rights or direct issuance of Common Stock are not applicable to grants made under the French Plan. In addition, in no case will grants under the French Plan include any other substitute awards, e.g., stock bonuses, cash awards or other similar awards.

2. Definitions

Capitalized terms used in the French Plan shall have the same meanings as set forth in the U.S. Plan.

In addition, the term “Option” shall have the following meaning:

Purchase Stock Options, that are rights to acquire Common Stock repurchased by the Company prior to the vesting of the Options; or

Subscription Stock Options, that are rights to subscribe newly issued Common Stock.

The term “Closed Period” means specific periods as set forth by section L. 225-177 of the French commercial code as amended during which French qualifying Options cannot be granted.

Notwithstanding any provisions in the U.S. Plan, the term “Grant Date” shall be the date on which the board both (a) designates the Optionee and (b) specifies the terms and conditions of the Option including the number of shares and the modalities to determine the Option Price.

Notwithstanding any provisions in the U.S. Plan to the contrary, for Options granted to French Optionees under the French Plan, no preferred stock in lieu of Common Stock may be issued.

The term “Effective Grant Date” shall be the date on which option is effectively granted, i.e. the date on which the condition precedent of the expiration of a Closed Period, if any, under which the option is granted, is satisfied. Such condition precedent shall be satisfied when the Committee or the body entitled thereto shall so determine, i.e. shall determine that the granting of options is no longer prevented under a Closed Period. If the Date of Grant does not occur within a Closed Period, the “Effective Grant Date” shall be the same day as the “Grant Date”.

The term “Vesting Date” shall mean the date on which an French Optionee’s right to all or a portion of an Option granted under the French Plan becomes non-forfeitable. The Vesting Date or Vesting Schedule shall be noted on the Stock Option Agreement entered into with each optionee.

The term “Exercise Date” shall mean the date on which a portion of Optionee’s Option becomes exercisable.

The term “Disposition Date” shall mean the first date on which the Optionee may make a Disposition of Shares.

The term “Disposition” shall mean a sale of Shares or transfer, assignment or any other similar event.

Under the French Plan, the Disposition Date shall be the fourth anniversary of the Effective Grant Date or, if different, on the date specified in Section 163 bis of the French Tax Code, as subsequently amended.

3. Entitlement to Participate

Any individual who is salaried employee or corporate Officer of a Subsidiary at the date of grant of the Option under the French Plan shall be eligible to receive Options under the French Plan provided that he or she also satisfies the eligibility conditions of Article I, section IV of the U.S. Plan. Options may not be issued under the French Plan to employees or officers owning more than ten percent (10%) of the Company’s share capital or to individuals other than employees and corporate officers of the Subsidiary. Options may not be issued to directors of the Subsidiary, other than managing directors (Président du Conseil d’Administration, Directeur Général, Directeur Général Délégué, Membre du Directoire, Gérant de sociétés par actions), unless they are employed by the Subsidiary.

4. Conditions and exercise of the Option / Option Price

Notwithstanding any provision in the U.S. Plan to the contrary, the conditions of the U.S. Plan, of the French Plan and of any Options granted thereunder (and as determined in the respective Stock Option Agreement) shall not be modified after the Effective Grant Date unless authorized by French law and subject to the prior written consent of the Optionee, and except that the Option price and number of shares may be modified as provided under Section 7 of the French plan. In this respect, the fact that French Optionees approve or would have approved such modification is irrelevant.

Notwithstanding any provision in the U.S. Plan to the contrary and since Common Stock of the Company are traded on a regulated securities market, no option may be granted to eligible optionees in France during specific Closed Periods as set forth by section L. 225-177 of the French commercial code as amended.

4.1. Vesting and exercisability

Vesting and exercisability of the option may be modified as provided in Section 5 of the French Plan.

The Options will vest and be exercisable pursuant to the terms and conditions set forth in the U.S Plan, the French Plan and under the respective Stock Option Agreement entered into with each Optionee.

I. The Vesting and exercisability of Options may be accelerated in accordance with the provisions of Section II, III A of the U.S. Plan. Notwithstanding any provisions of the U.S. Plan, the Disposition Date shall continue to be the fourth anniversary of the Effective Grant Date or, if different, on the date specified in Section 163 bis of the French Tax Code, as subsequently amended. The Vesting Date shall not be accelerated to any date that would result in the time period between the Disposition Date and the date of Vesting or exercisability which exceeds the maximum time allowed between such events under French law (i.e., under current law, restrictions on sale may continue for only three years from the date of exercise, so Vesting or exercisability shall be accelerated to a date no earlier than three years preceding the Disposition Date set forth above), except in the cases of dismissal, forced retirement, disability or death as defined by section 91-ter of Exhibit II to the French tax code and as construed by Tax Circulars and subject to the fulfilment of the related condition.

Specific provisions apply in the event of termination of employment/service and death as provided in Articles 6 and 8 below and as provided in the Stock Option Agreement entered into with each Optionee.

4.2. Option Price

II. The modalities of determination of the Option Price payable pursuant to Options issued hereunder shall be fixed by the Plan Administrator on the date the Option is granted. If Options are considered as granted on the Effective Date of Grant, Option Price will be determined in accordance with the modalities of the Option Price’s determination set forth by the Board on the Grant Date. In no event shall the Option price per share be less than the greater of:

with respect to Purchase Options over Common Stock, the higher of either 80% of the average quotation price of such Common Stock during the 20 days of quotation immediately preceding the Effective Grant Date or 80% of the average purchase price paid for such Common Stock by the Company;

with respect to Subscription Options over the Common Stock, 80% of the average quotation price of such Common Stock during the 20 days of quotation immediately preceding the Effective Grant Date; and

the minimum Option Price permitted under the U.S. Plan.

4.3. Exercise of an Option

The Options will become vested on the Vesting Date as defined under Section 2 above. However, notwithstanding the above, special provisions apply in the event of termination of employment due to death and disability (as defined hereunder) as follows:

In the event of the death of a French Optionee, outstanding Options shall be immediately vested and exercisable under the conditions set forth in Section 8 of the French Plan.

Notwithstanding any provisions in the U.S. Plan to the contrary, shares issued upon exercise of an Option shall be issued in the name of the French Optionee only, except in the event of death as referred to under Section 8 of the French Plan.

4.4. Payment of the Option Price

Notwithstanding any provisions in the U.S. Plan to the contrary, upon exercise of an Option, the full Option Price will be paid either in cash, by check or by credit transfer, exclusive of any other method of payment. Under a cashless exercise program, the French Optionee may give irrevocable instructions to a stockbroker to properly deliver the Option price to the Company. Notwithstanding any provisions in the U.S. Plan to the contrary, no delivery of prior owned shares having a fair market value on the date of delivery equal to the aggregate exercise price of the shares may be used as consideration for exercising the Options.

Furthermore, notwithstanding any provisions in the U.S. Plan to the contrary, shares owed to the French Optionee upon exercise may not be withheld in order to meet the tax

and/or social security contributions which might be due at the time of exercise or sale of the underlying Shares. However, upon sale of the underlying Shares, the Company and/or the Subsidiary shall have the right to withhold, or request any third party to withhold, from the proceeds to be paid to the French Optionee the sums corresponding to any social security contributions due at exercise or sale by the French Optionee. If such amounts are due and are not withheld, the French Optionee agrees to submit the amount due to the Subsidiary by means of check, cash or credit transfer.

The Shares acquired upon exercise of an Option will be recorded in an account in the name of the shareholder with a broker or in such other manner as the Company may otherwise determine in order to ensure compliance with applicable law, and any other applicable limitations or restrictions in the U.S. Plan, the French Plan, and the Stock Option Agreement, including limitations and restrictions on the Disposition or Disposition Date.

ARTICLE V 5. Non-transferability of Options

Notwithstanding any provision in the U.S. Plan to the contrary and except in the case of death, Options cannot be transferred to any third party. In addition, the Options are only exercisable by the French Optionee during the lifetime of the French Optionee.

ARTICLE VI 6. Termination of Employment/Service

If a termination of eligibility status is due to death, the Options shall be exercisable as set forth by Article 8 below.

In case of termination of eligibility status for other reasons than death, specific provisions regarding the exercise of the options by the Optionee are provided for in the Stock Option Agreement entered into with each Optionee.

ARTICLE VII 7. Changes In Capitalization

Notwithstanding any provisions of the U.S. Plan to the contrary, adjustments to the Option Price and/or the number of Shares subject to an Option issued hereunder shall be made to preclude the dilution or enlargement of benefits under the Option only in the event of one or more of the transactions listed below by the Company. Furthermore, even upon occurrence of one or more of the transactions listed below, no adjustment to the kind of shares to be granted shall be made (i.e., only shares of Common Stock shall be granted to French Optionees). The transactions are as follows:

an issuance of new shares for cash consideration reserved to the Company’s already existing shareholders;

an issuance of convertible or exchangeable bonds reserved to the Company’s existing shareholders;

a capitalization of retained earnings, profits, or issuance premiums;

a distribution of reserves by payment in cash or shares;

a cancellation of shares in order to absorb losses;

the repurchase of its own shares by a listed company at a price higher than the stock quotation price in the open market.

An increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company is not within the scope of the prohibition of the first paragraph of this Section 7.

ARTICLE VIII 8. Death

ARTICLE IX

ARTICLE X In the event of the death of a French Optionee, the Options shall become immediately vested, exercisable and available for Disposition. The French Optionee’s heirs may exercise the Option within six months following the death, even if the Option that was held by the deceased Optionee expires during this 6 month- period, but any Option which remains unexercised shall expire six months following the date of the Optionee’s death.

9. Term of the Option

The Term of the Option will be nine years and six months. This term can only be extended in the event of the death of the French Optionee.

ARTICLE XI 10. Interpretation

It is intended that Options granted under the French Plan shall qualify for the favorable tax and social security treatment applicable to stock options granted under Sections L225-177 to 225-186 of the French Commercial Code, as subsequently amended, and in accordance with the relevant provisions set forth by French tax law and the French tax administration. The terms of the French Plan shall be interpreted accordingly and in accordance with the relevant provisions set forth by French tax and social security laws, as well as the French tax and social security administrations.

In the event of any conflict between the provisions of the present French Plan and the U.S. Plan, the provisions of the French Plan shall control for any grants made thereunder to Optionees.

ARTICLE XII 11. Employment Rights

The adoption of this French sub-plan shall not confer upon the Participants any employment rights and shall not be construed as a part of the Participants employment contracts.

ARTICLE XIII 12. Adoption

The French Plan is effective as of July 1, 2001
