                             KENSEY NASH CORPORATION
                   TERMINATION AND CHANGE IN CONTROL AGREEMENT

      This TERMINATION AND CHANGE IN CONTROL AGREEMENT (the "Agreement") is
entered into effective as of the 1st day of June 2004, by and between Kensey
Nash Corporation (the "Company") and Douglas G. Evans, P.E. (the "Executive").

      WHEREAS, the Executive is employed by the Company and the Executive has
made valuable contributions to the strategic planning, business operations and
financial strength of the Company; and

      WHEREAS, the Company has determined that the Executive and the
availability of his future services are critical to the future success of the
Company; and

      WHEREAS, the Company desires to provide fair and reasonable protections to
the Executive on the terms and conditions set forth in this Agreement.

      NOW, THEREFORE, in consideration of the foregoing, and the continued
employment of the Executive, the Company and the Executive, each intending to be
legally bound hereby, covenant and agree as follows:

1.    The Company shall employ the Executive and Executive shall serve as the
      Company's Chief Operating Officer with the attendant responsibilities
      thereto. The Executive shall receive base compensation in the amount in
      effect as of the date of this Agreement, or Executive's most recent per
      annum base salary, whichever is greater, and be covered by and receive the
      benefits of those plans and programs providing other non-regular cash
      compensation and benefits under the terms and conditions in effect as of
      the date of this agreement. Nothing in this Agreement shall be deemed to
      supersede or otherwise limit the rights of the Executive to any amounts to
      which the Executive is entitled under any other agreement, plan, fund or
      program covering the Executive.

2.    In the event, following a Change in Control, the Company terminates the
      Executive's employment for a reason other than "Cause" (as defined herein)
      or the Executive quits his employment with the Company for "Good Reason"
      (as defined herein), the Executive shall be entitled to receive severance
      pay (the "Severance") equal to his regular base salary, or most recent per
      annum base salary whichever is greater, for a period of twenty-four (24)
      months (the "Payment Period"). Such Severance shall be in addition to any
      other compensation or benefits to which the Executive may be entitled
      under any other plan, program or payroll practice of the Company.

      Severance shall be paid in accordance with the Company's regular payroll
      practices as in effect at the time of payment and shall be subject to
      regular tax and other withholdings in effect with respect to the
      Executive's compensation prior to the Payment Period.

      The Company shall continue to provide Executive, during the Payment
      Period, with benefits no less favorable than those provided by the Company
      to senior executives of the Company during the six month period prior to
      the Change in Control. In addition, the Executive shall be entitled to
      receive a payment in an amount equal to two (2) times the average of his
      or her last two annual bonus payments earned, and such payment shall be
      issued no later than 60 days after Executive's Termination Date (as
      defined herein).

      The Company, however, shall not be required to provide additional accruals
      or contributions under any retirement plan qualified under Section 401(a)
      of the Internal Revenue Code.

      Severance shall terminate upon the death of Executive during the Payment
      Period.

3.    Upon a Change in Control, vesting of all unvested options granted to
      Executive shall accelerate such that Executive shall be immediately one
      hundred percent (100%) vested in all options awarded. Following a Change
      in Control, in the event of Executive's termination without cause or
      Executive's resignation for "Good Reason," options to purchase shares of
      common stock shall remain exercisable for a period of one (1) year from
      the date of such termination. The Company shall also pay the Executive any
      "Gross-Up Payments" as required under the Executive's employment agreement
      with the Company.

4.    All Benefits specified above are conditioned upon the Executive refraining
      from "Competition" with the Company and its affiliates during the twelve
      months after Executive ceases to be employed by the Company. If at any
      time

                                       86
<PAGE>

      prior to the end of such twelve month period, the Company determines that
      the Executive is engaging in Competition, the Company shall have the right
      to immediately suspend further payments hereunder.

      If the Executive engages in Competition at any time during the twelve
      month period, the Executive shall return all Benefits paid hereunder, and
      the Company shall be entitled to enforce the return of any Benefits
      previously paid.

      The Executive shall have the right to appeal any benefit suspension or
      request for return of benefits to the Board of Directors of the Company
      and, if it is determined that the Executive has not engaged in
      Competition, payment of all amounts due and unpaid shall be made as soon
      as reasonably practicable after such determination.

5.    The Benefits under this Agreement shall be unfunded, and the Company's
      obligation under this Agreement shall constitute an unsecured promise of
      severance pay.

6.    This Agreement shall be governed by the laws of Pennsylvania. If under
      governing law, any portion of this Agreement is deemed to be invalid, the
      invalidity of such portion shall not affect the force, effect and validity
      of any remaining portion of this Agreement.

7.    For purposes of this Agreement, the following definitions shall apply:

      "Cause" means any circumstance in which the Executive has been (i)
      convicted of a felony; or any circumstance in which the Company reasonably
      concludes that Executive's conduct with regard to the Company constitutes

      duty involving personal profit, or (iv) a material and continuing failure
      to perform stated duties.

            Act (other than shareholders holding more than 20% of the Company's
            voting securities as of the Effective Date), is or becomes the
            "beneficial owner" (as defined in Rule 13d-3 of the General Rules
            and Regulations under the Exchange Act), directly or indirectly, of
            securities of the Company representing 50% or more of the combined
            voting power of the company's then outstanding securities entitled
            to vote in the election of directors of the Company; or

      (b)   during any period of two consecutive years (not including any period
            prior to the Effective Date of this Plan) individuals who at the
            beginning of such period constituted the Board of Directors and any
            new directors, whose election by the Board of Directors or
            nomination for election by the stockholders of the Company was
            approved by a vote of at least three quarters of the directors then
            still in office who either were directors at the beginning of the
            period or whose election or nomination was previously so approved,
            cease for any reason to constitute at least a majority thereof; or

      (c)   all or substantially all of the assets of the Company are liquidated

      available to assist the Company or any affiliate in, or testify on behalf
      of the Company or any affiliate in any action, suit, or proceeding,
      whether civil, criminal or administrative.

      majority of the Company's stock or assets (iv) a relocation of the
      Executive's location of employment more than 50 miles from the location as

8.    Executive agrees, as a condition to the receipt of Severance provided for
      in this Agreement, that he will execute a release agreement, in a form
      satisfactory to the Company, releasing any and all claims arising out of
      Executive's employment, except for any claims pursuant to such other
      agreements, plans, funds or programs as referenced in Section 1 of this
      Agreement.

9.    Neither the terms of this Agreement nor the rights and obligations which

      assign this Agreement and the Company's rights and obligations as
      described herein, and shall assign this Agreement to any successor which,
      by operation of law or otherwise, continues to carry on substantially the
      business of the Company.

      agreement, plan, program or payroll practice, this Agreement constitutes
