(e) Equity Plans. 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.

(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.

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

(i) 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.

(ii) Upon any removal or resignation described in Section 4(a)(i) above, the Executive shall be entitled to receive, subject to the effectiveness of the Release, the following:

(1) The Executive shall receive cash severance (the “Cash Severance”) equal to the sum of (a) two (2) years of the Executive’s Annual Base Salary at the rate in effect immediately prior to 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 maximum target bonus for that year 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.

a. If the Executive is not a “specified employee” under Section 409A of the Code as of the Date of Termination, the Company shall pay the Cash Severance as follows:

i. If the Separation from Service 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 two (2) year 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 effective date of the Release. On the first payroll pay day following the effective date of the Release, 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 of the Release, with the balance of the Cash Severance being paid as originally scheduled.

ii. If the Separation from Service 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 effective date of the Release 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. If the Executive is a “specified employee” under Section 409A of the Code as of the Date of Termination, the Company shall pay the Cash Severance as follows:

i. If the Separation from Service does not occur immediately prior to, on or within twelve (12) months after a Change in Control, the Company will pay the entire amount of the Cash Severance in substantially equal installments on the Company’s regular payroll schedule and subject to standard deductions and withholdings over the eighteen (18) month period commencing on the date that is six (6) months after the Date of Termination.

ii. If the Separation from Service occurs immediately prior to, or within twelve (12) months after a Change in Control, the Cash Severance will be paid in a single lump sum on the date that is six (6) months after the Separation from Service.

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.

(b) 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.

(c) Disability. In the event that the Executive’s employment is terminated due to Disability, the Executive shall be entitled to receive all of the benefits described in Section 4(a) above, on all of the same payment terms and conditions (including execution of an effective Release), except that each reference to twenty-four (24) months shall be changed to twelve (12) months, each reference to two (2) years shall be instead to one (1) year and therefore each reference to eighteen (18) months shall be instead to six (6) months.

(d) Death. If the Executive dies while employed by the Company, the Company pay the Executive’s executor, legal representative, administrator or designated beneficiary (the “Heir(s)”) any amounts earned but not yet paid under Section 3 above and any benefits accrued or earned under the Company’s benefit plans and programs. In addition, subject to the Heir(s)’s execution of the Release, the Company will pay to the Heir(s), the following:

(i) The Company will pay a lump sum amount within thirty (30) days after the effectiveness of the Release equal to the sum of (1) twelve (12) months of the Executive’s monthly Annual Base Salary at the rate in effect on the Executive’s Date of Termination; (2) the Pro-Rated Bonus and (3) a lump sum payment equal to one (1) year of non-health insurance premiums, calculated as the product of (i) the aggregate monthly cost of the premiums the Executive would have paid upon conversion to individual policies of the life and disability insurance coverage for his eligible dependents under the Company’s policies, as in effect immediately prior to the Date of Termination and (ii) twelve (12) months.

(ii) If the Executive’s dependents timely elect continuation health care coverage pursuant to COBRA, the Company will pay the applicable COBRA premiums for such coverage for up to twelve (12) months, or such earlier date as the dependents cease to be eligible for such continuation coverage.

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

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. 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:

MUTUAL RELEASE OF CLAIMS

(To be signed on or within 21 days after the employment termination date.)

Pursuant to the terms of the Amended and Restated Employment Agreement (the “Agreement”) by and amongst VOLCANO CORPORATION (the “Company”), and VINCENT BURGESS (the “Executive”) effective as of February 10, 2010, the Company and the Executive hereby enter into the following Mutual Release of Claims (the “Release”):

1. Executive’s Release of Claims:

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).

the Released Parties, or under applicable law; or (ii) any rights which are not waivable 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 Chief Financial 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 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.
