RESTRICTED STOCK AWARD AGREEMENT

Pursuant to the Restricted Stock Award Grant Notice (“Grant Notice”) and this Restricted Stock Award Agreement (collectively, the “Award”) and in consideration of your future services, Ariosa Diagnostics, Inc. (the “Company”) has awarded you a stock award under its 2014 Equity Incentive Plan (the “Plan”) for the number of shares of the Company’s Common Stock subject to the Award as indicated in the Grant Notice. Defined terms not explicitly defined in this Restricted Stock Award Agreement but defined in the Plan shall have the same definitions as in the Plan.

The details of your Award are as follows:

1. VESTING. Subject to the limitations contained herein, your Award will vest as provided in the Grant Notice.

2. NUMBER OF SHARES. The number of shares subject to your Award may be adjusted from time to time for Capitalization Adjustments, as provided in the Plan.

3. SECURITIES LAW COMPLIANCE. You may not be issued any shares under your Award unless the shares are either (i) then registered under the Securities Act or (ii) the Company has determined that such issuance would be exempt from the registration requirements of the Securities Act. Your Award must also comply with other applicable laws and regulations governing the Award, and you will not receive such shares if the Company determines that such receipt would not be in material compliance with such laws and regulations.

4. MARKET STAND-OFF AGREEMENT. By acquiring shares of Common Stock under your Award, 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, prior to [            ], 2014, which is the date immediately following the one hundred eighty (180) days following the effective date of the registration statement of the Company that was filed under the Securities Act, or for such longer period as necessary to permit compliance with NASD Rule 2711 and similar or successor regulatory rules and regulations (the “Lock-Up Period”); provided, however, that nothing contained in this Section 4 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 Section 4 and shall have the right, power and authority to enforce the provision hereof as though they were a party hereto.

5. RIGHT OF REACQUISITION OF UNVESTED SHARES.

(a) The Company shall have a right to reacquire all or any part of the shares received pursuant to your Award (a “Reacquisition Right”) that have not as yet vested in accordance with the Vesting Schedule specified in your Grant Notice (“Unvested Shares”) on the following terms and conditions:

1.

(i) The Company shall simultaneously with termination of your Continuous Service (as defined in the Plan) automatically reacquire for no consideration all of the Unvested Shares, unless the Company agrees to waive its Reacquisition Right as to some or all of the Unvested Shares. Any such waiver shall be exercised by the Company by written notice to you or your representative (with a copy to the escrow agent party to the Joint Escrow Instructions attached to the Grant Notice (the “Escrow Agent”)) within ninety (90) days after the termination of your Continuous Service, and the Escrow Agent may then release to you the number of Unvested Shares not being reacquired by the Company. If the Company does not waive its Reacquisition Right as to all of the Unvested Shares, then upon such termination of your Continuous Service, the Escrow Agent shall transfer to the Company the number of Unvested Shares the Company is reacquiring.

(ii) The shares issued under your Award shall be held in escrow pursuant to the terms of the Joint Escrow Instructions attached to the Grant Notice as Attachment III. You agree to execute two (2) Assignment Separate From Certificate forms (with date and number of shares blank) substantially in the form attached to the Grant Notice as Attachment IV and deliver the same, along with the certificate or certificates evidencing the shares, for use by the escrow agent pursuant to the terms of the Joint Escrow Instructions.

(iii) Subject to the provisions of your Award, you shall, during the term of your Award, exercise all rights and privileges of a shareholder of the Company with respect to the shares deposited in escrow. You shall be deemed to be the holder of the shares for purposes of receiving any dividends which may be paid with respect to such shares and for purposes of exercising any voting rights relating to such shares, even if some or all of such shares have not yet vested and been released from the Company’s Reacquisition Right.

(iv) If, from time to time, there is any stock dividend, stock split or other change in the character or amount of any of the outstanding stock of the corporation the stock of which is subject to the provisions of your Award, then in such event any and all new, substituted or additional securities to which you is entitled by reason of your ownership of the shares acquired under your Award shall be immediately subject to the Reacquisition Right with the same force and effect as the shares subject to this Reacquisition Right immediately before such event.

6. RESTRICTIVE LEGENDS. The shares issued under your Award shall be endorsed with appropriate legends, if any, as determined by the Company.

7. AWARD NOT A SERVICE CONTRACT. Your Award is not an employment or service contract, and nothing in your Award 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 on the part of the Company or an Affiliate to continue your employment. In addition, nothing in your Award shall obligate the Company or an Affiliate, their respective shareholders, 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.

8. WITHHOLDING OBLIGATIONS.

(a) At the time your Award is made, 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 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 your Award.

2.

(b) Unless the tax withholding obligations of the Company and/or any Affiliate are satisfied, the Company shall have no obligation to issue a certificate for such shares or release such shares from any escrow provided for herein.

9. TAX CONSEQUENCES. The acquisition and vesting of the shares may have adverse tax consequences to you that may be avoided or mitigated by filing an election under Section 83(b) of the Internal Revenue Code, as amended (the “Code”). Such election must be filed within thirty (30) days after the date of your Award. YOU ACKNOWLEDGE THAT IT IS YOUR OWN RESPONSIBILITY, AND NOT THE COMPANY’S, TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(B), EVEN IF YOU REQUEST THE COMPANY TO MAKE THE FILING ON YOUR BEHALF.

10. NOTICES. Any notices provided for in your Award or the Plan shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered 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.

11. MISCELLANEOUS.

(a) The rights and obligations of the Company under your Award shall be transferable to any one or more persons or entities, and all covenants and agreements hereunder shall inure to the benefit of, and be enforceable by the Company’s successors and assigns. Your rights and obligations under your Award may only be assigned with the prior written consent of the Company.

(b) You agree upon request to execute any further documents or instruments necessary or desirable in the sole determination of the Company to carry out the purposes or intent of your Award.

(c) You acknowledge and agree that you have reviewed your Award in its entirety, have had an opportunity to obtain the advice of counsel prior to executing and accepting your Award and fully understand all provisions of your Award.

12. GOVERNING PLAN DOCUMENT. Your Award is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your Award, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of your Award and those of the Plan, the provisions of the Plan shall control.
