CARDIODYNAMICS INTERNATIONAL CORPORATION

2004 STOCK INCENTIVE PLAN

RESTRICTED STOCK AGREEMENT

SECTION 1. PAYMENT FOR SHARES.

No
payment is required for the shares that you are receiving.

SECTION 2. GOVERNING PLAN.

The shares that you are receiving are granted pursuant and subject in all respects to the applicable provisions of the CardioDynamics International
Corporation 2004 Stock Incentive Plan (the Plan), which is incorporated herein by reference. Terms not otherwise defined in this Agreement have meanings ascribed to them in the Plan.

SECTION 3. VESTING.

The shares that
you are receiving will vest in installments, as shown in the Notice of Restricted Stock Award.

No additional shares vest after your
common-law employment with the Company or a Subsidiary has terminated for any reason.

SECTION 4. SHARES RESTRICTED.

Unvested shares will be considered Restricted Shares. You may not sell, transfer, pledge or otherwise dispose of Restricted Shares without the
written consent of the Company. If permitted by the Company, you may transfer Restricted Shares to your spouse, children or grandchildren or to a trust established by you for the benefit of yourself or your spouse, children or grandchildren.
However, a transferee of Restricted Shares must agree in writing on a form prescribed by the Company to be bound by all provisions of this Agreement.

SECTION 5. FORFEITURE.

If your Service terminates for any reason, then your shares will be forfeited to the
extent that they have not vested before the termination date and do not vest as a result of termination. This means that the Restricted Shares will immediately revert to the Company. You receive no payment for Restricted Shares that are forfeited.
The Company determines when your Service terminates for this purpose.

SECTION 6. LEAVES OF ABSENCE AND PART-TIME WORK.

For purposes of this award, your Service does not terminate when you go on a military leave of absence, a sick leave of absence or another bona fide leave
of absence, if the leave of absence was approved by the Company in writing and if continued crediting of Service is required by the terms of the leave or by applicable law. Your Service will terminate when the approved leave of absence ends unless
you immediately return to active work.

SECTION 7. STOCK CERTIFICATES.

The certificates for Restricted Shares have stamped on them a special legend referring to the forfeiture restrictions. In addition to or in lieu of
imposing the legend, the Company may hold the certificates in escrow. As your vested percentage increases, you may request (at reasonable intervals) that the Company release to you a non-legended certificate for your vested shares.

SECTION 8. SHAREHOLDER RIGHTS.

During the period of time between the date of grant and the date the shares become vested, you shall have all the rights of a shareholder with respect to the shares except for the right to transfer the shares, as set forth in
Section 4. Accordingly, you shall have the right to vote the shares and to receive any cash dividends paid with respect to the shares.

SECTION
9. WITHHOLDING TAXES.

No stock certificates will be distributed to you unless any withholding taxes that may be due as a
result of this award or the vesting of the shares have been paid. By signing this Agreement, you authorize the Company or your actual employer to withhold all applicable withholding taxes legally payable by you. The Company, in its sole discretion,
will withhold shares of Common Stock that otherwise would be distributed to you when they vest to satisfy the withholding obligation, but not in excess of the amount of shares necessary to satisfy the minimum withholding amount. The Fair Market
Value of these shares, determined as of the date when taxes otherwise would have been withheld in cash, will be applied to the withholding taxes. You also authorize the Company, or your actual employer, to satisfy all withholding obligations of the
Company or your actual employer from your wages or other cash compensation payable to you by the Company or your actual employer.

SECTION 10.
RESTRICTIONS ON RESALE.

You agree not to sell any shares at a time when applicable laws, Company policies or an agreement
between the Company and its underwriters prohibit a sale. This restriction will apply as long as your Service continues and for such period of time after the termination of your Service as the Company may specify.

SECTION 11. NO RETENTION RIGHTS.

Your
award or this Agreement does not give you the right to be employed or retained by the Company or a subsidiary of the Company in any capacity. The Company and its subsidiaries reserve the right to terminate your Service at any time, with or without
cause.

SECTION 13. APPLICABLE LAW.

This Agreement will be interpreted and enforced under the
laws of the State of California (without regard to choice-of-law provisions).

SECTION 14. THE PLAN AND OTHER AGREEMENTS.

the Company regarding this award. Any prior agreements, commitments or negotiations concerning this award are superseded. This Agreement may be amended only by another written agreement between the parties.

SECTION 15. SUCCESSORS AND ASSIGNS.

of the Company.
