OPTION AGREEMENT

HANSEN MEDICAL, INC.

NON-PLAN

OPTION AGREEMENT

(NONSTATUTORY STOCK OPTION)

Pursuant to your Option Grant Notice (Grant Notice) and this Option Agreement, Hansen Medical, Inc. (the
Company) has grantcd you a stock option to purchase the number of shares of the Companys Common Stock indicated in your Grant Notice at the exercise price indicated in your Grant Notice. Capitalized terms are defined in
Section 17 of this Option Agreement.

The details of your option are as follows:

1. Vesting. Subject to the limitations contained herein, your option will vest as provided in your Grant Notice, provided that
vesting will cease upon the termination of your Continuous Service. Upon termination of your Continuous Service, this option will expire immediately with respect to any unvested option shares.

2. Number of Shares and Exercise Price. The number of shares of Common Stock subject to your option and your exercise price per
share referenced in your Grant Notice may be adjusted from time to time for Capitalization Adjustments.

3. Exercise
Restriction for Non-Exempt Employees. In the event that you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (i.e., a Non-Exempt Employee), you may not exercise
your option until you have completed at least six (6) months of Continuous Service measured from the Date of Grant specified in your Grant Notice, notwithstanding any other provision of your option.

4. Method of Payment. Payment of the exercise price is due in full upon exercise of all or any part of your option. You may elect
to make payment of the exercise price in cash or by check, bank draft or money order payable to the Company or in any other manner permitted by your Grant Notice, which may include one or more of the following:

(a) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal,
pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to
pay the aggregate exercise price to the Company from the sales proceeds.

(b) Provided that at the time of exercise the Common
Stock is publicly traded and quoted regularly in The Wall Street Journal, by delivery to the Company (either by actual delivery or attestation) of already-owned shares of Common Stock either that you have held for the period required to avoid
classification of your option as a liability for financial accounting purposes (generally six (6) months) or that you did not acquire, directly or indirectly from the



---

Company, that are owned free and clear of any liens, claims, encumbrances or security
interests, and that are valued at Fair Market Value on the date of exercise. Delivery for these purposes, in the sole discretion of the Company at the time you exercise your option, shall include delivery to the Company of your
attestation of ownership of such shares of Common Stock in a form approved by the Company. Notwithstanding the foregoing, you may not exercise your option by tender to the Company of Common Stock to the cxtent such tender would violate the
provisions of any law, regulation or agreement restricting the redemption of the Companys stock.

(c) Provided that at
the time of exercise the Company has adopted FAS 123, as revised, by a net exercise arrangement pursuant to which the Company will reduce the number of shares of Common Stock issued upon exercise of your option by the largest whole
number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company shall accept a cash or othcr payment from you to the extent of any remaining balance of the aggregate exercise price not
satisfied by such reduction in the number of whole shares to be issued; provided further, however, that shares of Common Stock will no longer be outstanding under your option and will not be exercisable thereafter to the extent that
(1) shares are used to pay the exercise price pursuant to the net exercise, (2) shares are delivered to you as a result of such exercisc, and (3) shares are withheld to satisfy tax withholding obligations.

5. Whole Shares. You may exercise your option only for whole shares of Common Stock.

6. Securities Law Compliance. Notwithstanding anything to the contrary contained herein, you may not exercise your option unless
the shares of Common Stock issuable upon such exercise are then registered under the Securities Act or, if such shares of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt from the
registration requirements of the Securities Act. The exercise of your option also must comply with other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would
not be in material compliance with such laws and regulations. The Company may, upon advice of counsel to the Company, place legends on stock certificates the shares of Common Stock issued under this option as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock.

7. Term. You may not exercise your option before the commencement or after the expiration of its term. The term of your option
commences on the Date of Grant and expires upon the earliest of the following:

(a) three (3) months after the
termination of your Continuous Service for any reason other than your Disability or death; provided, however, that if during any part of such three (3) month period your option is not exercisable solely because of the condition set forth
in Section 6, your option shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service;



5



---

(b) twelve (12) months after the termination of your Continuous Service due to your
Disability;

(c) eighteen (18) months after your death if you die either during your Continuous Service or within three
(3) months after your Continuous Service terminates;

(d) the Expiration Date indicated in your Grant Notice; or

(e) the day before the tenth (10th) anniversary of the Date of Grant.

8. Exercise.

(a) You may exercise the vested portion of your option during its term by delivering a Notice of Exercise (in a form designated by the
Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then require.

(b) By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter into an
arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (i) the exercise of your option, or (ii) the disposition of shares of Common Stock acquired upon such
exercise.

(c) By exercising your option, you agree that you shall not sell, dispose of, transfer, make any short sale of,
grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any shares of Common Stock or other securities of the Company held by you, for a period of time specified by the managing
underwriter(s) (not to exceed one hundred eighty (180) days) following the effective date of a registration statement of the Company filed under the Securities Act, other than a Form S-8 registration statement, (the Lock Up
Period); provided, however, that nothing contained in this section shall prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock Up Period. You further agree to execute and deliver such other
agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to your shares of Common Stock until the end of such period. The underwriters of the Companys stock are intended third party beneficiaries of this paragraph (c) and shall have the right, power and
authority to enforce the provisions hereof as though they were a party hereto.

9. Transferability. Your option is not
transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may
designate a third party who, in the event of your death, shall thereafter be entitled to exercise your option. In addition, you may transfer your option to a trust if you are considered to be the sole beneficial owner (determined under
Section 671 of the Code and applicable state law) while the option is held in the trust, provided that you and the trustee enter into transfer and other agreements required by the Company.

---

10. Option not a Service Contract. Your option is not an employment or service
contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your employment. In addition,
nothing in your option shall obligate the Company or an Affiliate, their respective stockholders, Boards of Directors, Officers or Employees to continue any relationship that you might have as a Director or Consultant for the Company or an
Affiliate.

11. Withholding Obligations.

(a) At the time you exercise your option, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize
withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a cashless exercise pursuant to a program developed under Regulation T as promulgated by the Federal
Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise of your option.

(b) Upon your request and subject to approval by the Company, in its sole discretion, and compliance with any applicable
legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock having a Fair Market Value, determined by the
Company as of the date of exercise, not in excess of the minimum amount required to be withheld by law (or such lower amount as may bc necessary to avoid classification of your option as a liability for financial accounting purposes). Any adverse
consequences to you arising in connection with such share withholding procedure shall be your sole responsibility.

(c) You
may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied. Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall
have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any escrow provided for herein unless such obligations are satisfied.

12. Adjustments Upon Changes in Common Stock; Other Corporate Events.

(a) In the event of a Capitalization Adjustment, the Board shall equitably adjust the class and number of securities and exercise price
per share of the stock subject to this option. The Board shall make such adjustments, and its determination shall be final, binding and conclusive.

(b) In the event of a dissolution or liquidation of the Company, this option shall terminate immediately prior to the completion of such
dissolution or liquidation, provided, however, that the Board may, in its sole discretion, cause some or all of the shares subject to this option to become vested and exercisable before the dissolution or liquidation is completed but contingent on
its completion.

(c) The following provisions shall apply if this option remains outstanding at the effective
time of a Corporate Transaction.

(i) In the event of a Corporate Transaction, any surviving corporation or acquiring
corporation (or the surviving or acquiring corporations parent company) may assume or continue this option or may substitute a similar stock award for this option (including, but not limited to, an award to acquire the same consideration paid
to the stockholders of the Company pursuant to the Corporate Transaction). A surviving corporation or acquiring corporation (or its parent) may choose to assume or continue only a portion of this option or substitute a similar award for only a
portion of this option. The terms of any assumption, continuation or substitution shall be set by the Board;

(ii) In the
event of a Corporate Transaction which occurs prior to the termination of your Continuous Service and in which the surviving corporation or acquiring corporation (or its parent company) does not assume or continue this option or substitute a similar
stock award for this option, then, with respect to the portion of this option that is not assumed, continued or substituted, the vesting and exercisability of this option shall (contingent upon the effectiveness of the Corporate Transaction) be
accelerated in full to a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five (5) days prior to the effective time of the
Corporate Transaction), and this option shall terminate if not exercised at or prior to the effective time of the Corporate Transaction.

(iii) In the event of a Corporate Transaction which occurs after the termination of your Continuous Service and in which the surviving
corporation or acquiring corporation (or its parent company) does not assume or continue this option or substitute a similar stock award for this option, then, with respect to the portion of this option that is not assumed, continued or substituted,
the vesting and exercisability of this option shall not be accelerated and this option shall terminate if not exercised prior to the effective time of the Corporate Transaction.

(iv) In the event this option will terminate if not exercised prior to the effective time of a Corporate Transaction, the Board may
provide, in its sole discretion, that if this option is not exercised prior to such effective time you will receive a payment, in such form as may be determined by the Board, equal to the excess, if any, of (A) the value of the property you
would have received upon exercise of the option over (B) any exercise price payable by you in connection with such exercise.

13. Administration. The Board shall administer this option and shall have the power:

(c) To accelerate the time at which the option will vest and become exercisable;

(d) To effect, at any time and from time to time, with your consent if you would be adversely affected, (l) the reduction of the

and/or (D) other valuable consideration (as determined by the Board in its sole discretion) or (3) any other action that would be treated as a repricing under generally accepted accounting principles. All determinations, interpretations
and constructions made by the Board in good faith shall not be subject to review by any person and shall be final, binding and conclusive on all persons.

14. Stockholder Rights. You shall not have any rights as a stockholder with respect to any shares subject to this option unless
and until you have exercised this option pursuant to its terms. You shall not be deemed to be a stockholder of record until the issuance of the shares pursuant to such exercise has been entered into the books and records of the Company.

15. Notices. Any notices provided for in your option shall be given in writing and shall be deemed effectively given upon receipt
or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company.

16. Choice of Law. The law of the State of California shall govern all questions concerning the construction, validity and
interpretation of this Option Agreement, without regard to such states conflict of law rules.

17. Definitions.

split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the

Employee or Consultant or a change in the entity for which the Optionholder renders such service, provided that there is no interruption or termination of the Optionholders service with the Company or an Affiliate, shall not terminate the
Optionholders Continuous Service. For example, a change in status from an employee of the Company to a consultant to an Affiliate shall not constitute an interruption of Continuous Service. To the extent permitted by law, the Board, in its
sole discretion, may determine whether Continuous Service shall be considered interrupted in the case of any leave of absence approved by that party, including sick leave, military leave or any other personal leave. Notwithstanding the foregoing, a
leave of absence shall be treated as Continuous Service for purposes of vesting of this option only to such extent as may be provided in the Companys leave of absence policy, in the written terms of any leave of absence agreement or policy
applicable to the Optionholder, or as otherwise required by law. Service solely as a Director, or payment of a fee for such service, shall not constitute Continuous Service for purposes of this option; and

409A(a)(2)(c)(i) of the Code.
