The determination of such date shall be made in good faith by the Board based on the applicable facts and circumstances.

(o)    “Severance Commencement Date” shall mean the date on or following the Date of Termination and on which the Release becomes effective and irrevocable in accordance with its terms; provided, however, that if the Date of Termination occurs within sixty (60) days prior to the end of a calendar year, the Severance Commencement Date will be the later of (i) the date on which the Release becomes effective and irrevocable in accordance with its terms, or (ii) the first day of the calendar year immediately following the Date of Termination.

(a)    Position and Duties. The Company shall employ the Executive to the position of President and Chief Executive Officer of the Company. During the Term, the Executive will devote substantially all of the Executive’s business efforts and time to the Company. The Executive agrees not to actively engage in any other employment, occupation or consulting activity for any direct or indirect remuneration without the prior approval of the Board, provided, however, that the Executive may engage in the following as long as such activities do not materially interfere with the Executive’s duties and responsibilities with the Company: (i) serve on the board of one (1) unaffiliated corporation; (ii) serve on the boards of trade associations or charitable organizations or otherwise engage in charitable activities and community affairs; or (iii) manage the Executive’s personal investments and affairs; provided, however, that Executive may serve on the Board of more than one unaffiliated corporation subject to the reasonable prior approval of the Board, which shall not be unreasonably withheld or delayed.

The Annual Base Salary amount shall be reviewed not less frequently than annually by the Board and, in the sole discretion of the Board, may be adjusted upward with such adjustments effective January 1 of the year in which any such adjustment is approved by the Board. Notwithstanding the preceding

sentence, the Executive’s annual salary may be reduced if such reduction is pro rata among substantially all of the Company’s senior level executives as a group.

(c)    Bonus. The Executive’s target bonus opportunity shall be one hundred percent (100%) of the Executive’s Annual Base Salary (the “Target Bonus”). This target percentage shall be reviewed not less frequently than annually by the Board and, in its sole discretion, may be adjusted upward. The Executive’s actual bonus earned shall be determined based on the Executive’s performance and achievement of target objectives and such other terms agreed to in good faith by the Company and the Executive.

(d)    Pension and Welfare Plans. During the Term, the Executive and the Executive’s dependents, if applicable, shall be entitled to participate in all incentive, savings and retirement plans, health and welfare benefit plans, practices, policies and programs (including, without limitation, medical, prescription, dental, disability, employee life, group life, accidental death and travel accident insurance plans and programs) sponsored by the Company or its affiliates on the same terms and conditions generally applicable to executives of the Company generally.

(e)    Equity Plans.

(i)    The Executive shall be entitled to participate in any stock option, restricted stock, stock appreciation rights, or any other equity compensation plan or program sponsored by the Company or its affiliates on the same terms and conditions generally applicable to executives of the Company. Notwithstanding the foregoing, except as expressly otherwise provided herein, the Executive shall not be entitled to awards under such plans at any time or in any particular amount. Any equity interests or rights to purchase equity interests in the Company held by the Executive and issued pursuant to the Volcano Corporation 2005 Equity Compensation Plan or any successor plan (the “Equity Plan”) shall be administered and subject to the terms of the Equity Plan and any amendments thereto, including, without limitation, the Equity Plan’s provisions relevant to a Change in Control.

(ii)    With respect to any stock option grants or other forms of exercisable equity awards that are awarded to Executive on or after the date of this Agreement, in the event of Executive’s termination of employment for any reason other than for Cause (as defined below), such equity awards shall, to the extent vested as of the Date of Termination, remain exercisable until the earlier of: (i) twelve (12) months following Executive’s Date of Termination, (ii) the expiration of such awards’ original maximum term, or (iii) termination of such equity awards under the terms of the Equity Plan in connection with a dissolution or liquidation of the Company, Corporate Transaction or Change in Control (as such terms are defined in the Equity Plan).

(f)    Designation as Qualified Performance-Based Compensation. The Company may determine that any bonus or equity awards issued under Sections 3(c) or 3(e) of this Agreement (“Awards”) shall be considered “qualified performance-based compensation” under Section 162(m) of the Code. Any Awards shall be administered by the Committee in accordance with this Section 3(f).

(g)    Fringe Benefits and Prerequisites. The Executive shall be entitled to fringe benefits and prerequisites available to executives in accordance with the plans, practices, programs and policies of the Company from time to time.

(h)    Expenses. The Executive shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by the Executive in accordance with the applicable policy of the Company and its affiliated companies.

(i)    Paid Time Off. The Executive shall be entitled to accrue such number of days per year of paid time off in accordance with the general policy of the Company.

4.    Termination. The Term and Executive’s employment shall terminate upon the occurrence of any of the following events:

(a)    Termination Without Cause; Resignation for Good Reason; Death; Disability.

(v)    The Company may remove the Executive at any time without Cause from the position in which the Executive is employed hereunder upon not less than thirty (30) days’ prior written notice of termination to the Executive; provided, however, that, in the event that such notice is given, the Executive shall be allowed reasonable time away from the office to seek other employment. In addition, the Executive may initiate termination of employment by resigning under this Section 4(a) for Good Reason. The Executive shall give the Company not less than thirty (30) days’ prior written notice of termination of such resignation for Good Reason.

(vi)    Upon any removal without Cause or resignation for Good Reason described in Section 4(a)(i) above or in the event of Executive’s death or termination of employment as a result of Disability (each a “Qualifying Termination”), the Executive shall be entitled to receive, subject to the effectiveness and irrevocability of the Release, the following severance benefits:

(1)    The Executive shall receive cash severance (the “Cash Severance”) equal to the sum of: (a) the greater of (i) four hundred percent (400%) of the Executive’s Annual Base Salary at the rate in effect immediately prior to the Date of Termination, or (ii) two hundred percent (200%) of the sum of (A) the Executive’s Annual Base Salary at the rate in effect immediately prior to the Date of Termination, plus (B) the largest amount of annual cash bonus actually paid to Executive within the two-year period preceding the date of termination; (b) a pro-rated bonus (the “Pro-Rated Bonus”) for the year in which the Date of Termination occurs, calculated as the product of (i) the bonus for that year which is actually earned and would otherwise be payable to the Executive based upon the level of attainment of the target objectives and other Target Bonus criteria as provided under Section 3(c) and (ii) a fraction, the numerator of which is the number of days during which the Executive was employed by the Company in the year in which the Date of Termination occurs, and the denominator of which is three hundred sixty five (365); and (c) two (2) years of non-health insurance premiums, calculated as the product of (i) the aggregate monthly cost of the premiums the Executive would pay upon conversion to individual policies of his life and disability insurance coverage under the Company’s policies, as in effect immediately prior to the Date of Termination and (ii) twenty-four (24) months,

(2)    If the Executive timely elects continuation health care coverage pursuant to COBRA for himself and/or his eligible dependents, the Company will pay the applicable COBRA premiums for such coverage for up to twenty-four (24) months, or such earlier time as the Executive ceases to be eligible for such continuation coverage; and

(3)    Executive’s outstanding equity awards that are subject to vesting solely upon the passage of time and Executive’s continued employment with the Company shall accelerate vesting in accordance with their applicable schedules as if Executive had remained in employment for an additional twenty-four (24) months as of the Date of Termination.

(vii)    Any Cash Severance Benefits will be paid to Executive as follows:

(1)    Subject to any delay in payment required by Section 4(d), if the Date of Termination does not occur immediately prior to, on or within twelve (12) months after a Change in Control, the Company will pay (1) the Cash Severance, less the Pro-Rated Bonus, in substantially equal installments on the Company’s regular payroll schedule and subject to standard deductions and withholdings over the twenty-four (24) month period immediately following the Date of Termination and (2) the Pro-Rated Bonus in a lump sum on the date that the Company would otherwise pay the annual bonus for that year to other executives whose employment has not terminated (but in no event later than March 15 of the year following the year in which the annual bonus would have otherwise been earned). However, no payments of the Cash Severance will be made prior to the Severance Commencement Date. On the first payroll pay day following the Severance Commencement Date, the Company will pay the Executive in a lump sum the Cash Severance the Executive would otherwise have received on or prior to such date but for the delay in payment related to the effectiveness and irrevocability of the Release, with the balance of the Cash Severance being paid as originally scheduled.

(2)    Subject to any delay in payment required by Section 4(d), if the Date of Termination occurs immediately prior to, on or within twelve (12) months after a Change in Control, (1) the Cash Severance, less the Pro-Rated Bonus, will be paid in a single lump sum on the first regular payroll pay day following the Severance Commencement Date and (2) the Pro-Rated Bonus will be paid in a lump sum on the date that the Company would otherwise pay the annual bonus for that year to other executives whose employment has not terminated (but in no event later than March 15 of the year following the year in which the annual bonus would have otherwise been earned).

(b)    Qualifying Termination in Connection with a Change in Control. If Executive’s employment terminates due to a Qualifying Termination that occurs during the period commencing ninety (90) days prior to the effective date of a Change in Control and ending twelve (12) months following the effective date a Change in Control, then subject to Executive’s timely provision of an effective and irrevocable Release, and effective as of the later of the Severance Commencement Date or the effective date of the Change in Control, Executive’s equity awards will accelerate vesting in full; provided, however, that in order to give effect to the intent of the foregoing provision, to the extent the Severance Commencement Date is later than the effective date of a Change in Control where the Executive’s equity award is not assumed, substituted or continued by the acquiring or surviving entity, the vesting of Executive’s equity awards will be contingent upon

Executive’s timely provision of an effective and irrevocable Release, but will be deemed to have been effective immediately prior to the Change in Control. For purposes of determining the number of shares that will vest pursuant to the foregoing provision with respect to any performance based vesting equity award that has multiple vesting levels depending upon the level of performance, vesting acceleration shall occur with respect to the number of shares subject to the equity award as if the applicable performance criteria had been attained at a 100% level. In order to give effect to the intent of the foregoing provision, notwithstanding anything to the contrary set forth in Executive’s equity award agreements or the Equity Plan under which such equity award was granted that provides that any then unvested portion of the equity award will immediately expire upon the Executive’s termination of service, no unvested portion of the Executive’s equity award shall generally terminate any earlier than ninety (90) days following any Qualifying Termination of the Executive’s employment that occurs prior to the effective date of a Change in Control; provided, however that after giving effect to the vesting acceleration provisions set forth above, the Executive’s equity awards shall remain subject to earlier termination in connection with a Corporate Transaction (as defined in the Equity Plan) in which the Executive’s equity award is not assumed, substituted or continued by the acquiring or surviving entity as provided in the Equity Plan or substantially equivalent provisions applicable to the Executive’s equity award.

(c)    Termination for Cause; Voluntary Resignation Without Good Reason. In the event that the Executive voluntarily terminates his employment for any reason other than Good Reason or in the event that Company terminates the Executive for Cause no further payments shall be due under this Agreement, except that the Executive shall be entitled to any amounts earned, accrued or owing but not yet paid under Section 3 above and any benefits accrued or earned under the Company’s benefit plans and programs or to which Executive is otherwise entitled under applicable law.

(d)    Compliance with Section 409A of the Code.

(iii)    It is intended that each installment of the payments provided for in this Section 4 is a separate “payment” for purposes of Treasury Regulations Section 1.409A-2(b)(2)(i). For the avoidance of doubt, it is intended that payments of the amounts set forth in this Section 4 satisfy, to the greatest extent possible, the exemptions from the application of Section 409A provided under Treasury Regulation 1.409A-1(b)(4) and 1.409A-1(b)(9)(v).

(iv)    Any provision of this Agreement to the contrary notwithstanding if at the time of the Executive’s Date of Termination Executive is a "specified employee," within the meaning of Section 409A of the Code, then to the extent any payment or benefit that the Executive becomes entitled to under this Agreement on account of his Separation from Service would be considered nonqualified deferred compensation under Section 409A of the Code, such payment or benefit shall be paid or provided at the date which is the earlier of (i) six (6) months and one day after the Date of Termination and (ii) the date of the Executive’s death (the "Delay Period"). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section 4(d) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or provided to the Executive in a lump-sum, and any remaining payments

and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

(v)    Any reimbursements provided under this Agreement that constitute deferred compensation within the meaning of Section 409A of the Code shall be made or provided in accordance with the requirements of Section 409A of the Code, including, without limitation, that (i) in no event shall any fees, expenses or other amounts eligible to be reimbursed by the Company under this Agreement be paid later than the last day of the calendar year next following the calendar year in which the applicable fees, expenses or other amounts were incurred; (ii) the amount of expenses eligible for reimbursement in any given calendar year shall not affect the expenses that the Company is obligated to reimburse in any other calendar year, provided that the foregoing clause (ii) shall not be violated with regard to expenses reimbursed under any arrangement covered by Code Section 105(b) solely because such expenses are subject to a limit related to the period the arrangement is in effect; (iii) the Executive’s right to have the Company pay or provide such reimbursements may not be liquidated or exchanged for any other benefit; and (iv) in no event shall the Company's obligations to make such reimbursements apply later than the Executive’s remaining lifetime.

5.    Non-Disclosure; Proprietary Information and Inventions, etc. The Executive agrees to continue to be bound and abide by the Information and Inventions Agreement. Executive also acknowledges that nothing in this Agreement relieves the Executive of his obligations under the Patent, Copyright and Nondisclosure Agreement.

6.    Limitation on Payments; Section 280G. In the event the severance and other benefits provided for in this Agreement or otherwise payable to Executive (i) are "parachute payments" within the meaning of Section 280G of the Internal Revenue Code (the "Code") and (ii) but for this Section 6, would be subject to the "golden parachute" excise tax imposed by Section 4999 of the Code, then Executive's severance benefits will be either:

(a)delivered in full, or

(a)    delivered as to such lesser extent which would result in no portion of such severance benefits being subject to the excise tax under Section 4999 of the Code,

whichever of (a) or (b), taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, results in the receipt by Executive on an after-tax basis, of the greatest amount of severance benefits. If a reduction in the severance and other benefits constituting "parachute payments" is necessary so that no portion of such severance benefits is subject to excise tax under Section 4999 of the Code, the reduction shall occur in the following order: (1) reduction of the cash severance payments; (2) cancellation of accelerated vesting of equity awards; and (3) reduction of continued employee benefits. In the event that acceleration of vesting of equity award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of Executive's equity awards. Unless the Company and Executive otherwise agree in writing, any determination required under this Section 6 will be made by the Company’s independent accounting firm, whose determination will be conclusive and binding upon Executive and the Company for all purposes.

7.    Miscellaneous.

(a)    Legal Costs. The Company shall reimburse the Executive for reasonable legal fees and expenses incurred if the Executive prevails on any issue which is the subject of such of a lawsuit or arbitration brought by the Executive or the Company as a result of any dispute with any party (including, but not limited to, the Company and/or any affiliate of the Company) regarding the provisions of this Agreement. Otherwise, the Executive and the Company shall be responsible for its own legal fees and expenses in connection with such action. The Company will reimburse the Executive for reasonable legal fees and expenses directly relating to the negotiation of this Agreement.

(b)    Arbitration. In the event of any dispute under the provisions of this Agreement, other than a dispute in which the primary relief sought is an equitable remedy such as an injunction, the parties shall be required to have the dispute, controversy or claim settled by arbitration in San Diego, California in accordance with the National Rules for the Resolution of Employment Disputes then in effect of the American Arbitration Association, before a panel of three arbitrators, two of whom shall be selected by the Company and the Executive, respectively, and the third of whom shall be selected by the other two arbitrators. Any award entered by the arbitrators shall be final, binding and nonappealable and judgment may be entered thereon by either party in accordance with applicable law in any court of competent jurisdiction. This arbitration provision shall be specifically enforceable. The arbitrators shall have no authority to modify any provision of this Agreement or to award a remedy for a dispute involving this Agreement other than a benefit specifically provided under or by virtue of the Agreement.

(c)    No Mitigation. The Company agrees that, if the Executive’s employment is terminated during the Term, the Executive is not required to seek other employment or to attempt in any way to reduce any amounts payable to the Executive by the Company pursuant to this Agreement. Further, the amount of any payment or benefit provided for in Section 4 of this Agreement shall not be reduced by any compensation earned by the Executive as the result of employment by another employer, by retirement benefits, or offset against any amount claimed to be owed by the Executive to the Company or any of their respective subsidiaries. However, the severance benefits provided under this Agreement are intended to satisfy, to the greatest extent possible, any and all statutory obligations that may arise out of the Executive’s termination of employment including, without limitation, the Worker Adjustment and Retraining Notification Act.

(d)    Successors. In addition to any obligations imposed by law upon any successor to the Company, the Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place.

(e)    Binding Agreement. This Agreement shall inure to the benefit of and be enforceable by the Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Executive shall die while any amount would still be payable to the Executive hereunder (other than amounts which, by their terms,

terminate upon the death of the Executive) if the Executive had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the executors, personal representatives or administrators of the Executive’s estate.

(f)    Notices. For the purpose of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by United States certified mail, return receipt requested, postage prepaid, addressed to the respective addresses set forth below, or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notice of change of address shall be effective only upon actual receipt:

Executive understands that, on the last date of his employment with the Company, the Company will pay him any accrued salary and accrued and unused vacation to which he is entitled by law, regardless of whether he signs this Release, but he is not entitled to the severance benefits provided in the Agreement unless he signs and returns this Release to the Company and allows it to become effective.

In exchange for payment of benefits set forth in Section 4 of the Agreement, Executive hereby generally and completely releases the Company and its directors, officers, employees, shareholders, partners, agents, attorneys, predecessors, successors, parent and subsidiary entities, insurers, affiliates, and assigns (collectively the “Released Parties”) of and from any and all claims, liabilities and obligations, both known and unknown, arising out of or in any way related to events, acts, conduct, or omissions occurring at any time prior to or at the time that Executive signs this Release (the “Executive Released Claims”). This general release includes, but is not limited to: (1) all claims arising out of or in any way related to Executive’s employment with the Company or the termination of that employment; (2) all claims related to Executive’s compensation or benefits from the Company, including salary, bonuses, commissions, vacation pay, expense reimbursements, severance pay, fringe benefits, stock, stock options, or any other ownership or equity interests in the Company; (3) all claims for breach of contract, wrongful termination, and breach of the implied covenant of good faith and fair dealing (including claims based on or arising under the Agreement); (4) all tort claims, including claims for fraud, defamation, emotional distress, and discharge in violation of public policy; and (5) all federal, state, and local statutory claims, including claims for discrimination, harassment, retaliation, attorneys’ fees, or other claims arising under the federal Civil Rights Act of 1964 (as amended), the federal Americans with Disabilities Act of 1990, the federal Age Discrimination in Employment Act (as amended) (“ADEA”), the federal Family and Medical Leave Act, the California Labor Code (as amended), the California Family Rights Act, and the California Fair Employment and Housing Act (as amended).

Executive understands that notwithstanding the foregoing, the following are not included in the Executive Released Claims (the “Executive Excluded Claims”): (i) any rights or claims for indemnification Executive may have pursuant to any written indemnification agreement to which he is a party, the charter, bylaws, or operating agreements of any of the Released Parties, or under applicable law; (ii) any rights or claims pursuant to any directors and officers liability insurance policy of which Executive is a direct or indirect beneficiary; (iii) any rights or claims to compensation or benefits to which Executive has a vested or non-forfeitable right as of his termination of employment with the Company; (iii) any rights or claims to enforce any provisions of the Agreement or (iv) any rights which cannot be waived as a matter of law. In addition, Executive understands that nothing in this Release prevents him from filing, cooperating with, or participating in any proceeding before the Equal Employment Opportunity Commission, the Department of Labor, or the California Department of Fair Employment and Housing, except that Executive acknowledges and agrees that he shall not recover any monetary benefits in connection with any such claim, charge or proceeding with regard to any claim released herein. Executive hereby represents and warrants that, other than the Executive Excluded Claims, Executive is not aware of any claims he has or might have against any of the Released Parties that are not included in the Executive Released Claims.

Executive acknowledges that he is knowingly and voluntarily waiving and releasing any rights he may have under the ADEA, and that the consideration given for the waiver and release in the preceding paragraph is in addition to anything of value to which he is already entitled. Executive further acknowledges that he has been advised by this writing that: (1) his waiver and release do not apply to any rights or claims that may arise after the date he signs this Release; (2) he should consult with an attorney prior to signing this Release (although he may choose voluntarily not to do so); (3) he has twenty-one (21) days to consider this Release (although he may choose voluntarily to sign it earlier); (4) he has seven (7) days following the date he signs this Release to revoke it by providing written notice of revocation to the Chairman of the Company’s Board of Directors; and (5) this Release will not be effective until the date upon which the revocation period has expired, which will be the eighth calendar day after the date Executive signs it provided that he does not revoke it and that the Company has signed this Release by such date (the “Effective Date”).

Executive hereby represents that he has been paid all compensation owed and for all hours worked, he has received all the leave and leave benefits and protections for which he is eligible, pursuant to the Family and Medical Leave Act, the California Family Rights Act, or otherwise, and he has not suffered any on-the-job injury for which he has not already filed a workers’ compensation claim.

2.    Company’s Release of Claims:

The Company hereby generally and completely releases Executive of and from any and all claims, liabilities, and obligations, both known and unknown, arising out of or in any way related to events, acts, conduct or omissions occurring at any time prior to or at the time the Company signs this Release (the “Company Released Claims”); provided, however, that this Release shall not extend to: (1) any claims that may arise out of any events, acts, conduct or omissions occurring after this Release is executed, including without limitation, any claims for breach of the Agreement; (2) any claims arising at any time out of Executive’s obligations to protect the Company’s proprietary information, including without limitation, any claims arising from Executive’s obligations under his Information and Inventions Agreement and his Patent, Copyright and Nondisclosure Agreement, claims arising under the California Uniform Trade Secrets Act, or common law claims arising from these obligations; or (3) any claims arising from any actions by Executive which were intentional or amount to gross negligence during his employment with the Company which were outside of his authority as President and Chief Executive Officer or outside of the course and scope of his employment (the “Company Excluded Claims”).

The Company hereby represents and warrants that, other than the Company Excluded Claims, it is not aware of any claims it has or might have against Executive that are not included in the Company Released Claims.

3.    Section 1542 Waiver:

THE PARTIES UNDERSTAND THAT THIS AGREEMENT INCLUDES A RELEASE OF ALL KNOWN AND UNKNOWN CLAIMS. The parties acknowledge that each has read and understands Section 1542 of the California Civil Code which reads as follows: “A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.” The parties hereby expressly waive and relinquish all rights and benefits under that section and any law or legal principle of similar effect in any jurisdiction with respect to their respective release of claims herein, including but not limited to their releases of unknown and unsuspected claims.

4.    Additional Agreements:

The parties hereby further agree as follows: (1) Executive agrees not to disparage the Company, its parent, or its or their officers, directors, employees, shareholders, affiliates and agents, in any manner likely to be harmful to its or their business, business reputation, or personal reputation, and the Company agrees not to, and agrees to instruct its executives, representatives and members of its Board of Directors not to, disparage Executive in any manner likely to be harmful to his business reputation or personal reputation (although the parties may respond accurately and fully to any question, inquiry or request for information as required by legal process); (2) not to voluntarily (except in response to legal compulsion) assist any third party in bringing or pursuing any proposed or pending litigation, arbitration, administrative claim or other formal proceeding against the other party, or against the Released Parties; and (3) to reasonably cooperate with the other party, by voluntarily (without legal compulsion) providing accurate and complete information, in connection with such other party’s actual or contemplated defense, prosecution, or investigation of any claims or demands by or against third parties, or other matters, arising from events, acts, or failures to act that occurred during the period of Executive’s employment by the Company.
