Non-Statutory Stock Option Agreement

(Under the 2003 Stock Option Plan - Director)

This is a Non-Statutory Stock Option Agreement (the “Agreement”) between Tactile Systems Technology, Inc., a Minnesota corporation (the “Company”), and the optionee identified above (the “Optionee”) effective as of the date of grant specified above.

BACKGROUND

A.                                    The Company maintains the Tactile Systems Technology, Inc. 2003 Stock Option Plan (the “Plan”).

B.                                    Under the Plan, the Board of Directors of the Company (the “Board”) or a committee of two or more directors of the Company (the “Committee”) appointed by the Board administers the Plan and has the authority to determine the awards to be granted under the Plan (if the Board has not appointed a committee to administer the Plan, then the Board shall constitute the Committee).

C.                                    The Committee has determined that the Optionee is eligible to receive an award under the Plan in the form of a non-statutory stock option (the “Option”).

D.                                    The Company hereby grants the Option to the Optionee under the terms and conditions as follows.

TERMS AND CONDITIONS*

1.                                      Grant.  The Optionee is granted the Option to purchase the number of Shares specified at the beginning of this Agreement.

*                                         Unless the context indicates otherwise, terms that are not defined in this Agreement shall have the meaning set forth in the Plan as it currently exists or as it is amended in the future.

2.                                      Exercise Price.  The price to the Optionee of each Share subject to the Option will be the exercise price specified at the beginning of this Agreement.

3.                                      Non-Statutory Stock Option.  The Option is not intended to be an “incentive stock option” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”).

4.                                      Exercise Schedule.  The Option will vest and become exercisable as to the number of Shares and on the dates specified in the exercise schedule at the beginning of this Agreement, in each case only if the Optionee was providing Services to the Company (as defined in Section 7 of this Agreement) on such date.  The exercise schedule will be cumulative; thus, to the extent the Option has not already been exercised and has not expired, terminated or been cancelled, the Optionee or the person otherwise entitled to exercise the Option as provided herein may at any time, and from time to time, purchase all or any portion of the Shares then purchasable under the exercise schedule.

The Option may also be exercised in full (notwithstanding the exercise schedule) under the circumstances described in Section 7 of this Agreement if it has not expired prior thereto.

5.                                      Expiration.  The Option will expire at 5:00 p.m. Central Time on the earliest of:

(a)                                 The expiration date specified at the beginning of this Agreement;

(b)                                 The expiration of the period after the termination of Service of the Optionee to the Company within which the Option can be exercised (as specified in Section 7 of this Agreement);

(c)                                  At the election of the Company, upon termination of the Optionee’s Service to the Company for Cause or if it is determined by the Company within ten days after termination of the Optionee’s Service to the Optionee, such as Optionee’s resignation, that Cause existed for termination by the Company; or

(d)                                 The date (if any) fixed for cancellation pursuant to paragraph 11(c) or 12 of the Plan.

In no event may anyone exercise the Option, in whole or in part, after it has expired, notwithstanding any other provision of this Agreement.

6.                                      Procedure to Exercise Option.

Notice of Exercise.  The Option may be exercised by delivering written notice of exercise to the Company at the principal executive office of the Company, to the attention of the Company’s Secretary, in the form attached to this Agreement.  The notice shall state the number of Shares to be purchased, and shall be signed by the person exercising the Option.  If the person exercising the Option is not the Optionee, he/she also must submit appropriate proof of his/her right to exercise the Option.

Tender of Payment.  Upon giving notice of any exercise hereunder, the Optionee shall provide for payment of the purchase price of the Shares being purchased through one or a combination of the following methods:

(a)                                 Cash (including check, bank draft or money order);

(b)                                 Cancellation of indebtedness owed to the Optionee by the Company or any parent or subsidiary thereof;

(c)                                  To the extent permitted by law, through a broker-assisted cashless exercise in which the Optionee simultaneously exercises the Option and sells all or a portion of the Shares thereby acquired pursuant to a brokerage or similar relationship and uses the proceeds from such sale to pay the purchase price of such Shares;

2

(d)                                 By delivery to the Company of unencumbered Shares having an aggregate Fair Market Value on the date of exercise equal to the purchase price of such Shares; or

(e)                                  By authorizing the Company to retain, from the total number of Shares as to which the Option is exercised, that number of Shares having a Fair Market Value on the date of exercise equal to the purchase price for the total number of Shares as to which the Option is exercised.

Notwithstanding the foregoing, the Optionee shall not be permitted to pay any portion of the purchase price with Shares, or by authorizing the Company to retain Shares upon exercise of the Option, if the Committee, in its sole discretion, determines that payment in such manner is undesirable nor may the Company permit the Optionee, if he or she is an executive officer or director of the Company, to pay for the Shares by delivery of a promissory note from an after such time, if any, that the Company (i) has a class of securities registered under Section 12 of the Exchange Act, (ii) is required to file reports under Section 15(d) of the Exchange Act or (iii) that has filed a registration statement that has not yet become effective under the Securities Act.

Delivery of Certificates.  As soon as practicable after the Company receives the notice and purchase price provided for above, it shall deliver to the person exercising the Option, in the name of such person, a certificate or certificates representing the Shares being purchased.  The Company shall pay any original issue or transfer taxes with respect to the issue or transfer of the Shares and all fees and expenses incurred by it in connection therewith.  All Shares so issued shall be fully paid and nonassessable.  Notwithstanding anything to the contrary in this Agreement, no certificate for Shares distributable under the Plan shall be issued and delivered unless the issuance of such certificate complies with all applicable legal requirements including, without limitation, compliance with the provisions of applicable state securities laws, the Securities Act and the Exchange Act.

7.                                      Service Requirement.  The Option may be exercised only while the Optionee provides services to the Company as a member of its Board of Directors (such director services are referred to collectively in this Agreement as “Service” or “Services”) and only if the Optionee has been continuously providing such Services since the date the Option was granted; provided that:

(a)                                 The Option may be exercised for three months after termination of the Optionee’s Service with the Company if such cessation of the Optionee’s Service is for a reason other than death or disability, but only to the extent that it was exercisable immediately prior to termination of Service to the Company, provided that if termination of the Optionee’s Service shall have been for Cause, the Option shall expire, and all rights to purchase Shares hereunder shall terminate, immediately upon such termination.

(b)                                 The Option may be exercised for one year after termination of the Optionee’s Service if such termination of Service is because of death or disability of the Optionee.

(c)                                  If the Optionee’s Service terminates after a declaration made pursuant to paragraph 12 of the Plan in connection with an Event, the Option may be exercised at any time permitted by such declaration.

Notwithstanding the above, the Option may not be exercised after it has expired.

8.                                      Acceleration of Vesting.

Death or Disability.  In the event of the death or disability of the Optionee, any portion of the Option that was not previously exercisable shall become immediately exercisable in full if the Optionee shall have been continuously providing Services to the Company or a parent or subsidiary thereof between the date the Option was granted and the date of such death or disability.

3

Change in Control.  If a Change in Control of the Company shall or is to occur, then, at the discretion of the Committee, the Option, if not already exercised in full or otherwise terminated, expired or cancelled, may become immediately exercisable in full and/or remain exercisable during the remaining term of the Option.

Event.  In the event of an Event, at the time of any declaration pursuant to clause (ii) of the first sentence of paragraph 12 of the Plan, the Option, if not already exercised in full or otherwise terminated, expired or cancelled, may, at the discretion of the Committee, become immediately exercisable in full and/or remain exercisable during the period preceding the time of cancellation of the Option pursuant to such declaration.

Discretionary Acceleration.  Notwithstanding any other provisions of this Agreement to the contrary, the Committee may, in its sole discretion, declare at any time that the Option shall be immediately exercisable.

9.                                      Limitation on Transfer.  During the lifetime of the Optionee, only the Optionee or his/her guardian or legal representative may exercise the Option.  The Option may not be assigned or transferred by the Optionee otherwise than by will or the laws of descent and distribution or pursuant to a qualified domestic relations order as defined by the Code or Title I of the Employee Retirement Income Security Act, or the rules thereunder; provided, however, that the Optionee may transfer the Option to a member or members of his/her immediate family (i.e., his/her children, grandchildren and spouse) or to one or more trusts for the benefit of such family members or partnerships in which such family members are the only partners, if the Optionee does not receive any consideration for the transfer.  The Option held by any such transferee shall continue to be subject to the same terms and conditions that were applicable to the Option immediately prior to its transfer and may be exercised by such transferee as and to the extent that the Option has become exercisable and has not terminated in accordance with the provisions of the Plan and this Agreement.

10.                               No Shareholder Rights Before Exercise.  No person shall have any of the rights of a shareholder of the Company with respect to any Share subject to the Option until the Share actually is issued to him/her upon exercise of the Option.

11.                               Discretionary Adjustment.  In the event of any reorganization, merger, consolidation, recapitalization, liquidation, reclassification, stock dividend, stock split, combination of shares, rights offering, or extraordinary dividend or divestiture (including a spin-off), or any other change in the corporate structure or Shares of the Company, the Committee (or if the Company does not survive any such transaction, a comparable committee of the Board of Directors of the surviving corporation) may, without the consent of the Optionee, make such adjustment as it determines in its discretion to be appropriate as to the number and kind of securities subject to and reserved under the Plan and, in order to prevent dilution or enlargement of rights of the Optionee, the number and kind of securities issuable upon exercise of the Option and the exercise price hereof.

12.                               Tax Withholding.  Delivery of Shares upon exercise of the Option shall be subject to any required withholding taxes.  As a condition precedent to receiving Shares upon exercise of the Option, the Optionee may be required to pay to the Company, in accordance with the provisions of paragraph 9 of the Plan, an amount equal to the amount of any required withholdings.  In lieu of all or any part of such a cash payment, a person exercising the Option may cover all or any part of the required withholdings, and any additional withholdings up to the amount needed to cover the individual’s full FICA and federal, state and local income tax liability with respect to income arising from the exercise of the Option, through the delivery to the Company of unencumbered Shares, through a reduction in the number of Shares delivered to the person exercising the Option or through a subsequent return to the Company of Shares delivered to the person exercising the Option (in each case, such Shares having an aggregate Fair Market Value on the date of exercise equal to the amount of the withholding taxes being paid through such delivery, reduction or

4

subsequent return of Shares).  Notwithstanding the foregoing, no person shall be permitted to pay any such withholdings with Shares, or through a reduction in the number of Shares to be delivered upon exercise of the Option, if the Committee, in its sole discretion, determines that payment in such manner is undesirable.

13.                               Interpretation of This Agreement.  All decisions and interpretations made by the Committee with regard to any question arising hereunder or under the Plan shall be binding and conclusive upon the Company and the Optionee.  If there is any inconsistency between the provisions of this Agreement and the Plan, the provisions of the Plan shall govern.

14.                               Option Subject to Plan, Articles of Incorporation and By-Laws.  The Optionee acknowledges that the Option and the exercise thereof is subject to the Plan, the Articles of Incorporation, as amended from time to time, and the By-Laws, as amended from time to time, of the Company, and any applicable federal or state laws, rules or regulations.

15.                               Obligation to Reserve Sufficient Shares.  The Company shall at all times during the term of the Option reserve and keep available a sufficient number of Shares to satisfy this Agreement.

16.                               Binding Effect.  This Agreement shall be binding in all respects on the heirs, representatives, successors and assigns of the Optionee.

17.                               Choice of Law.  This Agreement is entered into under the laws of the State of Minnesota and shall be construed and interpreted thereunder (without regard to its conflict of law principles).

18.                               Tax Consequences.

(a)                                 The Optionee may incur tax liability as a result of the Optionee’s purchase or disposition of the Shares.  THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES.

(b)                                 Notwithstanding the Company’s good faith determination of the Fair Market Value of the Company’s common stock for purposes of determining the exercise price per Share of the Option, the taxing authorities may assert that the fair market value of the Company’s common stock on the date of grant was greater than the exercise price per Share.  Under Section 409A of the Code, if the exercise price per Share of the Option is less than the fair market value of the Company’s common stock on the date of grant, the Option may be treated as a form of deferred compensation and the Optionee may be subject to an additional 20% tax, plus interest and possible penalties.  The Optionee is encouraged to consult a tax adviser regarding the potential impact of Section 409A of the Code.

19.                               Amendment to Meet the Requirements of Section 409A.  The Optionee acknowledges that the Company, in the exercise of its sole discretion and without the consent of the Optionee, may amend or modify this Agreement in any manner and delay the payment of any amounts payable pursuant to this Agreement to the minimum extent necessary to meet the requirements of Section 409A of the Code as amplified by any Internal Revenue Service or U.S. Treasury Department regulations or guidance as the Company deems appropriate or advisable.
