OPTION AGREEMENT

Pursuant to your Option Grant Notice (“Grant Notice”) and this Option Agreement,
Hansen Medical, Inc. (the “Company”) has granted 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 pmi 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 delivety 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 extent 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 other 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 exercise, 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 patt 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;

--------------------------------------------------------------------------------

(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 be 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.

price pel’ share of the stock subject to this option. The Board or the
Compensation Committee shall make such adjustments, and such patty’s
determination shall be final, binding and conclusive.

shall terminate immediately prior to the completion of such dissolution or
liquidation, provided, however,

--------------------------------------------------------------------------------

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

the effective time of a Corporate Transaction.

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 or the
Compensation Committee shall determine (or, if the Board or Compensation

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

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.
