Re:    Separation Agreement and Release

Dear Dave:

As we discussed with you, your employment with Cardiovascular Systems, Inc. (“CSI”) will end effective at the close of business on February 26, 2016. The purpose of this Separation Agreement and Release letter (“Agreement”) is to set forth the specific separation pay and benefits CSI will provide to you in keeping with the CSI Amended and Restated Executive Officer Severance Plan dated February 27, 2015 (the “Severance Plan”) in exchange for your agreement to the terms and conditions of this Agreement.

 

By your signature below, you agree to the following terms and conditions:

1.    End of Employment.    Your employment with CSI will end effective at the close of business on February 26, 2016 (the “Separation Date”). Except as set forth herein, upon your receipt of your final paycheck for services through the Separation Date, you will have received all wages, commissions and compensation owed to you by virtue of your employment with CSI or termination thereof. With your final paycheck, you will also receive payment from CSI for accrued but unused Paid Time Off (PTO) at your regular rate. Any deferred compensation benefits payable to you will be paid pursuant to the terms of the Cardiovascular Systems, Inc. Deferred Compensation Plan (the “Deferred Compensation Plan”).

You and your eligible family members will be eligible for early retiree medical benefits pursuant to the terms and conditions of CSI’s group health plan, as may be amended from time to time. This early retiree medical coverage is in lieu of any payment of COBRA premiums by CSI as described in the Severance Plan. When your early retiree medical coverage ends, you and your eligible family members may be entitled to COBRA at your expense if and as applicable under federal and state law.

Page 2

By signing below, you agree that as of the Separation Date, you will be deemed to have automatically resigned from all positions with CSI including, without limitation, from CSI’s Board of Directors and all other governing bodies of CSI and its subsidiaries, if and as applicable. In addition, concurrently with your execution of this Agreement, you agree to provide written notice to CSI’s Corporate Secretary of your resignation as required by CSI’s Amended and Restated Bylaws, in the form attached hereto as Exhibit A.

    

You are not eligible for any other payments or benefits by virtue of your employment with CSI or termination thereof except for those expressly described in this Agreement. You will not receive the pay and benefits described in Section 2 of this Agreement if you (i) do not sign this Agreement and return it to CSI by the Offer Expiration, (ii) rescind this Agreement after signing it, or (iii) violate any of the terms and conditions set forth in this Agreement, Section 8 - 14 of your Employment Agreement, the Severance Plan, or any other written agreement in effect between you and CSI containing post-employment obligations. In addition, the pay and benefits described in Section 2 of this Agreement shall be subject to reduction, cancellation, forfeiture, offset or recoupment as and to the extent required by the applicable provisions of any law (including without limitation Section 10D of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder), government regulation or stock exchange listing requirement, or clawback policy or provision implemented by CSI pursuant to such law, regulation or listing requirement.

2.    Separation Pay and Benefits.      Specifically in consideration of your signing this Agreement and subject to the limitations, obligations, and other provisions contained in this Agreement, CSI agrees to the following as set forth in and subject to the Severance Plan:

a.To pay you, or your estate in accordance with section 13 below, twenty-four (24) months of Salary Continuation Benefits based on your ending Base Salary, in the gross amount of One Million Two Hundred Sixty Thousand and 00/100 ($1,260,000.00), less applicable deductions and withholding. Your Salary Continuation Benefits will be paid to you as follows: (i) you will receive $44,166.67 per month, beginning with the payroll date coinciding with or immediately following the 60^th day after the Separation Date, if the rescission periods described in Section 5 have expired without rescission prior to the 60^th day, and (ii) you will receive $52,500 per month, beginning with the payroll date coinciding with or immediately following the first day of the seventh (7^th) month following the Separation Date; however, the first monthly payment shall include a lump sum payment of $50,000 for the additional amount that otherwise would have been paid to you during the six-month period following your Separation Date.

b.To pay you, or your estate in accordance with section 13 below, a pro rata bonus under the Fiscal Year 2016 bonus plan in which you participated, prorated for your period of employment during such bonus period (July 1, 2015 through the Separation Date). Bonuses under such plan will be calculated following the close of Fiscal Year 2016 and, if any bonus is owing to you hereunder, such bonus will be paid to you by October 15, 2016.

c.To accelerate the vesting of 27,140 of your time vested shares of restricted stock that were previously granted to you that would have vested within the 12 month period following the Separation Date had you remained employed by CSI during such period, such that they are deemed fully vested as of the expiration of the rescission periods described in Section 5 below without rescission by you;

d.To provide for the vesting of up to 112,072 of your performance based shares of restricted stock that were previously granted to you that would have otherwise become vested during the 12 month period following the Separation Date had you remained employed by CSI during such period, provided the performance criteria for such vesting are met as determined by CSI in accordance with the terms for such shares of restricted stock (in or around August or September 2016) such that, if and to the extent applicable, such shares will vest as of such determination; and

e.Permit any of your outstanding stock options as of the Separation Date to remain exercisable through the award expiration date, as set forth on Exhibit B attached hereto.

3.    Release of Claims. Specifically in consideration of the pay and benefits described in Section 2, to which you would not otherwise be entitled, by signing this Agreement you, for yourself and anyone who has or obtains legal rights or claims through you, agree to the following:
