EXHIBIT 10.27


                         EXECUTIVE EMPLOYMENT AGREEMENT


This Agreement is made as of October 29, 2002 (the "Effective Date") between
CNS, INC. a Delaware corporation ("CNS") and Linda Kollofski ("Employee").

WHEREAS, CNS considers the establishment and maintenance of a sound and vital
management to be essential to protecting and enhancing the best interests of CNS
and its shareholders; and

WHEREAS, Employee has made and is expected to continue to make, due to his
experience and knowledge, a significant contribution to the profitability,
growth and financial strength of CNS; and

WHEREAS, CNS, as a publicly held corporation, recognizes that the possibility of
a change in control may exist and that such possibility and the uncertainty and
questions which it may raise among management may result in the departure or
distraction of the performance of Employee's duties to the detriment of CNS and
its shareholders; and

WHEREAS, Employee is willing to continue his employment with CNS upon the
understanding that CNS will provide income security if Employee's employment is
terminated under certain terms and conditions;

WHEREAS, it is in the best interests of CNS and its stockholders to employ
Employee and to reinforce and encourage his continued attention and dedication
to his assigned duties without distraction and to ensure his continued
availability to CNS in the event of a Change in Control; and

WHEREAS, it is further in CNS's best interests to receive certain assurances
from Employee regarding CNS's confidentiality, competition and other proprietary
business concerns;

THEREFORE, in consideration of the foregoing and of this agreement, certain
change in control protection, continued employment and other benefits hereunder,
as well as other mutual covenants and obligations hereinafter set forth, CNS and
Employee agree as follows:

1.   Employment. CNS agrees to continue to employ Employee as its Vice
     President, New Business Development under the terms, conditions and
     benefits set forth herein and Employee accepts continued employment with
     CNS on said terms, conditions and benefits.

2.   Term. The term of Employee's employment shall continue until terminated
     pursuant to paragraph 6, 7, or 8 herein.

3.   Duties. In his position as Vice President, New Business Development,
     Employee will continue to faithfully and diligently perform such executive
     management responsibilities as may be assigned to him from time to time by
     the Chief Executive Officer, President or Chairman of the Board of
     Directors of CNS (the "Board"); devote his full time, energy and skill to
     CNS's business, as is reasonably necessary to execute fully his duties
     hereunder, except for vacations, absences made necessary because of
     illness, and service on other corporate, civic, or charitable boards or
     committees not significantly interfering with his duties hereunder; and
     promote CNS's best interests. The principal place of employment and the
     location of Employee's principal office and normal place of work shall be
     in the Minneapolis, Minnesota metropolitan area. Employee will be expected
     to travel to other locations, as necessary, in the performance of his
     duties during the term of this Agreement. Employee shall notify the
     President of any other paid position which he is considering accepting,
     including but not limited to a board of directors position, a position as
     an employee or an independent consultant, or any position, whether or not
     for pay, which could constitute a conflict of interest with CNS. The
     Employee agrees not to accept any such position without the President of
     CNS's prior approval.

4.   Compensation. For all services rendered by Employee, CNS shall pay Employee
     the compensation described in Exhibit A, payable at such times as salaried
     employees of CNS are customarily paid. The President of CNS shall, from
     time to time during Employee's employment, review his annual salary in
     connection with possible increases, giving consideration to inflation
     factors, performance of Employee and CNS, salaries paid for positions of
     similar responsibility for other companies, and other relevant factors, and
     shall provide for such increases when deemed appropriate. Employee shall in
     addition be eligible to participate in the annual management incentive
     bonus program, as approved by the Board of Directors. In the event of
     termination of this Agreement by CNS without Good Cause, as defined in
     paragraph 7 herein, the Board may, in good faith and in its sole
     discretion, determine and cause to be paid a partial bonus based on
     Employee's performance through the date of termination, and such
     determination shall be final and binding.

5.   Benefits. Employee shall be entitled to Paid Time Off consistent with CNS
     policy and such insurance, 401(k) program and other benefits available to
     all salaried employees of CNS, subject to any limitations on such benefits
     to officers, directors or highly paid employees in order that such benefit
     programs qualify under federal or state law for favored tax or other
     treatment. Such benefit programs may be changed from time to time by the
     Board. Employee shall also be entitled to reimbursement of his reasonable
     and necessary expenses incurred in connection with the performance of his
     duties hereunder.

6.   Termination by Employee. Employee may resign his employment with CNS
     effective upon 30 days' advance written notice to the President. If
     Employee resigns under this paragraph, the President retains the right to
     terminate his employment, effective upon written notice to Employee, at any
     time during the 30-day notice period, provided, however, that base salary
     and the employer portion of his health insurance premiums will continue to
     be paid by CNS for the duration of the 30-day notice period. In connection






EXECUTIVE EMPLOYMENT AGREEMENT
PAGE 3


     with his termination, Employee will receive any accrued unused Paid Time
     Off to which he is entitled.

7.   Termination by CNS. CNS shall have the right to terminate Employee's
     employment in any of the following ways:

     a.   CNS may, by written notice to Employee, terminate his employment
          without Good Cause, in which event Employee will be paid his base
          salary up to the date of termination. Employee is also entitled to
          receive Salary Continuation for one year from his termination date.
          "Salary Continuation" shall mean payment by CNS of the Employee's base
          salary as of his termination date, payable to Employee on the same
          schedule and in the same amount as the payment of base salary prior to
          termination of his employment, until such time as the full Salary
          Continuation obligation shall be discharged, as provided in this
          paragraph 7. During the period when Salary Continuation is payable to
          Employee, CNS will also continue to provide to Employee all group
          medical, dental and life plan benefits provided to its other senior
          executives. Employee shall also receive any accrued unused Paid Time
          Off to which he is entitled. Receipt of Salary Continuation is subject
          to Employee's compliance with his obligations under paragraphs 9, 10,
          11 and 12 of this Agreement and his execution of a standard release
          agreement which includes, in addition to release of claims against CNS
          and related releasees, an obligation not to speak negatively about or
          harm CNS, confidentiality with respect to the termination process, and
          cooperation with the transition of responsibilities. Payment of the
          employer portion of Employee's group medical, dental and life plan
          premiums under this paragraph and under paragraphs 6 and 8 herein
          shall cease as of the date on which Employee is covered under other
          such group plans if such coverage occurs prior to termination of any
          salary continuation periods set forth in said paragraphs.

     b.   CNS, by written notice to Employee, may terminate his employment for
          Good Cause, as defined below. In the event of termination under this
          subparagraph 7.b., Employee shall be paid his base salary up to the
          date of termination. "Good Cause" for the purpose of this Agreement
          shall mean one or more of the following: (i) willful and premeditated
          failure or refusal of Employee to render services to CNS in accordance
          with his obligations under paragraph 3; (ii) the commission by
          Employee of an act of fraud or embezzlement against CNS; (iii) the
          commission by Employee of any other willful or reckless act which
          injures CNS in a substantial or material way (it being understood that
          mere negligence in performance of duties is not Good Cause under this
          Agreement); (iv) the breach by Employee of any provision of this
          Agreement; or (v) the commission of a substantial act of moral
          turpitude by Employee which is deemed by CNS's Board to have a
          material adverse effect on CNS; or (vi) unsatisfactory performance
          after specific notice of performance deficiencies, description of
          expectations and opportunity to cure.

     c.   CNS, by written notice to Employee, may terminate Employee's
          employment under this Agreement if he becomes physically or mentally
          disabled during the term so that he has not been able to substantially
          perform, for a period of 120 consecutive days, with reasonable
          accommodation, the usual duties assigned to him hereunder
          ("Disability"). Upon such determination, CNS shall pay to Employee his
          base salary up to the date of such termination to the extent not
          covered by any disability plan.

     d.   This Agreement shall terminate upon the Employee's death during its
          term, except that CNS shall pay to the legal representative of
          Employee's estate all base salary due him up to the date of his death.

8.   Termination Following a Change in Control.

DEFINITION.

     a.   For purposes of this Agreement, "Change in Control" shall mean the
          occurrence of one of the following events:

          i.   ACQUISITION OF 25% OF STOCK IN CNS
               any "person" [as such term is used in Section 13(d) and 4(d) of
               the Securities Exchange Act of 1934, as amended ("Exchange
               Act")], other than a trustee or other fiduciary holding
               securities under an employee benefit plan of CNS is or becomes
               the "beneficial owner" (as defined in Rule 13d-3 under the
               Exchange Act), directly or indirectly of securities representing
               25% or more of the combined voting power of CNS's then
               outstanding securities;

          ii.  CHANGE IN 50% OF BOARD DIRECTORS WHO WERE NOT APPROVED BY BOARD
               during any period of two consecutive years (not including any
               period ending prior to the effective date of this Agreement),
               individuals who at the beginning of such period constitute the
               Board of Directors of CNS, and any new director [other than a
               director designated by a person who has entered into agreement
               with CNS to effect a transaction permitted by Section 6(a)(I),
               (iii) or (iv)] whose election by the Board of Directors of CNS or
               nomination for election by CNS's stockholders was approved by
               vote of at least two-thirds of the directors then still in office
               who either were directors at the beginning of the period or whose
               election or nomination for election was previously so approved
               ("Continuing Directors"), cease for any reason to constitute at
               least a majority of the Board of Directors of CNS;

          iii. MERGER OR CONSOLIDATION WHERE CNS SHAREHOLDERS OWN LESS THAN 50%
               OF SURVIVING COMPANY'S STOCK
               the stockholders of CNS approve a merger or consolidation of CNS
               with






EXECUTIVE EMPLOYMENT AGREEMENT
PAGE 3


               any other corporation, other than (A) a merger or consolidation
               which would result in the voting securities of CNS outstanding
               immediately prior thereto continuing to represent (either by
               remaining outstanding or by being converted into voting
               securities of the merged or consolidated entity) 50% or more of
               the combined voting power of the voting securities of CNS or such
               merged or consolidated entity outstanding immediately after such
               merger or consolidation, or (B) a merger or consolidation
               effected to implement a recapitalization of CNS or similar
               transaction in which no "person" acquires more than 25% of the
               combined voting power of CNS's then outstanding securities;

          iv.  SALE OF CNS ASSETS FOR VALUE TOTALING 50% OR MORE OF CNS STOCK
               MARKET VALUE
               the stockholders of CNS approve a plan of complete liquidation or
               a sale or disposition by CNS of all or substantially all of CNS's
               assets. "The sale or disposition by CNS of all or substantially
               all of CNS's assets" shall mean a sale or other disposition
               transaction or series of related transactions involving assets of
               CNS or of any direct or indirect subsidiary of CNS (including the
               stock of any direct or indirect subsidiary of CNS) in which the
               value of the assets or stock being sold or otherwise disposed of
               (as measured by the purchase price being paid therefor or by such
               other method as the Board of Directors of CNS determines is
               appropriate in a case where there is no readily ascertainable
               purchase price) constitutes more than 50% of the fair market
               value of CNS. For purposes of the preceding sentence, the "fair
               market value of CNS" shall be the aggregate market value of CNS's
               outstanding common stock (on a fully diluted basis) plus the
               aggregate market value of CNS's other outstanding equity
               securities. The aggregate market value of CNS's common stock
               shall be determined by multiplying the number of shares of CNS
               common stock (on a fully diluted basis) outstanding on the date
               of the execution and delivery of a definitive agreement
               ("Transaction Date") with respect to the sale or disposition by
               CNS of all or substantially all of CNS's assets by the average
               closing price for CNS's common stock for the ten trading days
               immediately preceding the Transaction Date. The aggregate market
               value of any other equity securities of CNS shall be determined
               in a manner similar to that prescribed in the immediately
               preceding sentence for determining the aggregate market value of
               CNS's common stock or by such other method as the Board of
               Directors of CNS shall determine is appropriate; and

          Employee agrees that, subject to the terms and conditions of this
          Agreement, in the event of a Change in Control of CNS occurring after
          the date hereof, Employee will remain in the employ of CNS for a
          period of 30 days from the occurrence of such Change in Control.






EXECUTIVE EMPLOYMENT AGREEMENT

     b.   Applicability. In the event of a Change in Control, the terms of this
          subparagraph 8.b shall be effective for a period of 24 months
          following the Change in Control. At the expiration of such 24 month
          period this Agreement in its entirety shall be terminated and be of no
          further effect. Employee shall be entitled to receive the benefits set
          forth in subparagraph 8.f if, within 24 months of such Change in
          Control, his employment is terminated by CNS or its successor without
          Good Cause (as defined in paragraph 7.a above), or by Employee for
          Good Reason (as defined in subparagraph 8.b.i, below). Employee shall,
          in return for the benefits provided under subparagraph 8.f., sign a
          standard release agreement with CNS, in which he agrees to release any
          and all claims and causes of action which he might have against CNS
          and in which he affirms and acknowledges his obligations under
          paragraphs 9, 10, 11 and 12 of this Agreement.

          i.   Termination for Good Reason shall be effective immediately upon
               written notice from the Employee to the President. Good Reason
               shall exist if CNS has materially breached any of the terms of
               this Agreement; Employee is assigned duties which are materially
               inconsistent with his position, duties, responsibilities and
               status as Vice President, New Business Development; his
               compensation, including any incentive compensation or bonus plan,
               is reduced; or relocation of CNS would require him to relocate
               his principal residence outside reasonable commuting distance of
               the Twin Cities Metropolitan area.

          ii.  Termination without Good Cause shall be effective upon 30 days'
               advance notice by CNS to the Employee. For purposes of this
               paragraph 8, Good Cause shall be defined as in subparagraph 7.b.

     c.   Notice of Termination. Any purported termination of employment under
          this paragraph 8 and also under paragraphs 6 and 7 shall be
          communicated by written Notice of Termination to the other party
          hereto in accordance with paragraph 20 hereunder. For purposes of this
          Agreement, a "Notice of Termination" shall mean a notice which
          indicates the specific termination provision in this Agreement relied
          upon and which sets forth the facts and circumstances claimed to
          provide a basis for termination of Employee's employment.

     d.   Date of Termination. For purposes of this paragraph 8 and also
          paragraphs 6 and 7 of this Agreement, "Date of Termination" shall
          mean:

          i.   if Employee's employment is terminated for Disability, as defined
               in paragraph 7.c. hereunder, 30 days after Notice of Termination
               is given (provided that Employee shall not have returned to the
               full-time performance of Employee's duties during such 30 day
               period); and






EXECUTIVE EMPLOYMENT AGREEMENT
PAGE 7


          ii.  if Employee's employment is terminated pursuant to a provision
               contained in paragraph 6, 7 or 8 herein or for any other reason
               (other than Disability), the date specified in the Notice of
               Termination, consistent with the provisions in said paragraphs.

     e.   Dispute of Termination. If, within ten days after any Notice of
          Termination is given under this paragraph 8, the party receiving such
          Notice of Termination notifies the other party that a dispute exists
          concerning the termination, the Date of Termination shall be the date
          on which the dispute is finally determined, either by mutual written
          agreement of the parties, or by a final judgment, order or decree of a
          court of competent jurisdiction (which is not appealable or the time
          for appeal therefrom having expired and no appeal having been
          perfected); provided, that the Date of Termination shall be extended
          by a notice of dispute only if such notice is given in good faith and
          the party giving such notice pursues the resolution of such dispute
          with reasonable diligence. Notwithstanding the pendency of any such
          dispute, CNS shall continue to pay Employee full compensation in
          effect when the notice giving rise to the dispute was given
          (including, but not limited to, base salary) and continue Employee as
          a participant in all compensation, benefit and insurance plans in
          which Employee was participating when the notice giving rise to the
          dispute was given, to the extent permissible under the terms of the
          applicable group plans and state and federal law, until the dispute is
          finally resolved in accordance with this subparagraph. Amounts paid
          under this subsection are in addition to all other amounts due under
          this Agreement and shall not be offset against or reduce any other
          amounts under this Agreement.

     f.   Compensation Upon Termination. Following a Change in Control, as
          defined in subparagraph 8.a. above, to the extent provided in
          subparagraph 8.b. above, Employee shall be entitled to the following
          benefits in lieu of any benefits which would otherwise be available to
          him upon termination under paragraphs 6 or 7 hereunder:

          i.   CNS shall pay Employee through the Date of Termination Employee's
               base salary at the rate in effect at the time the Notice of
               Termination is given and any other form or type of other
               compensation otherwise payable for such period, including any
               applicable incentive bonus, commensurate with his performance and
               the performance of CNS.

          ii.  In lieu of any further salary payments for periods subsequent to
               the Date of Termination, CNS shall pay a severance payment (the
               "Severance Payment") equal to 24 months of Employee's
               Compensation as defined below based on the average monthly
               Compensation paid to Employee during the 24 month period ending
               immediately prior to the Date of Termination (without giving
               effect to any reduction in such Compensation which would
               constitute a breach of this Agreement). If the Employee has not
               been employed by CNS for 24 months as of the Date of Termination,






EXECUTIVE EMPLOYMENT AGREEMENT
PAGE 8


               average monthly Compensation shall be the Employee's average
               monthly Compensation for the number of months during which the
               Employee has been employed at CNS. For purposes of this
               subparagraph, Compensation shall mean and include every type and
               form of compensation paid to Employee by CNS (or any corporation
               ("Affiliate") affiliated with CNS within the meaning of Section
               1504 of the Internal Revenue Code of 1986, as may be amended from
               time to time (the "Code")) and included in Employee's gross
               income for federal income tax purposes, but excluding
               compensation income arising from (1) hiring bonuses and (2)
               compensation income recognized as a result of the exercise of
               stock options or sale of the stock so acquired. All of Employee's
               contributions to any qualified plan pursuant to Section 401(k) of
               the Code or any flexible benefit plan pursuant to Section 125 of
               the Code shall be deemed to be included in gross income for
               federal tax purposes for purposes of this subparagraph. The
               Severance Payment shall be made in a single lump sum within 60
               days after the Date of Termination.

          iii. For 18 months following the Employee's Date of Termination, CNS
               shall arrange to provide, at its sole expense, Employee with
               group medical, dental and life plan benefits substantially
               similar to those which Employee was receiving or entitled to
               receive immediately prior to the Notice of Termination. The cost
               of providing such benefits shall be in addition to (and shall not
               reduce) the Severance Payment. Benefits otherwise receivable by
               Employee pursuant to this paragraph (iii) shall be reduced to the
               extent comparable benefits are actually received by Employee
               during such period from any third party, and any such benefits
               actually received by Employee shall be reported to CNS.

          iv.  CNS shall also pay to Employee all legal fees and expenses
               incurred by Employee as a result of such termination (including
               all such fees and expenses, if any, incurred in contesting or
               disputing any such termination or in seeking to obtain or enforce
               any right or benefit provided by this paragraph).

          v.   The Severance Payment shall be reduced and offset by the amount
               of any other payment received or to be received by Employee in
               connection with his termination of employment pursuant to any
               policies of CNS.

          vi.  If a determination is made by legislation, regulations, rulings
               directed to CNS or Employee, or court decision that the aggregate
               amount of any payment made to Employee hereunder, or pursuant to
               any plan, program or policy of CNS in connection with, on account
               of, or as a result of, a Change of Control constitutes an "excess
               parachute payment" as defined in Section 280G of the Code subject
               to the excise tax provisions of Section 4999 of the Code, or any
               successor sections thereof, Employee shall be






EXECUTIVE EMPLOYMENT AGREEMENT
PAGE 9


               entitled to receive from CNS, in addition to any other amounts
               payable hereunder, an amount which shall be equal to such excise
               tax, plus, on a net after-tax basis, an amount equal to the
               aggregate amount of any interest, penalties, fines or additions
               to any tax, including income tax, which are imposed in connection
               with the imposition of such excise tax. Such amount shall be
               payable to Employee as soon as may be practicable after such
               final determination is made. Employee and CNS shall mutually and
               reasonably determine whether or not such determination has
               occurred or whether any appeal to such determination should be
               made.

          vii. Employee shall be entitled to receive all benefits payable to
               Employee under the CNS, Inc. Profit Sharing Plan and Trust or any
               successor of such Plan and Trust and any other plan or agreement
               relating to retirement benefits, and, in addition, if Employee is
               not fully vested in his account balance under such Plan, a single
               lump sum payment in cash from CNS representing the nonvested
               portion of his account, which shall be in addition to, and not
               reduced by, any other amounts payable to Employee under this
               paragraph 8.

         viii. Employee shall not be required to mitigate the amount of any
               payment provided for in this paragraph 8 by seeking other
               employment or otherwise, nor shall the amount of any payment or
               benefit provided for in this paragraph 8 be reduced by any
               compensation earned by Employee as the result of employment by
               another employer or by retirement benefits after the Date of
               Termination, or otherwise except as specifically provided in this
               paragraph 8.

          ix.  In order to assure the performance of CNS or its successor of its
               obligations under this paragraph, CNS may deposit in trust an
               amount equal to the maximum payment that will be due Employee
               under the terms hereof. Under a written trust instrument, the
               Trustee shall be instructed to pay to Employee (or Employee's
               legal representative, as the case may be) the amount to which
               Employee shall be entitled under the terms hereof, and the
               balance, if any, of the trust not so paid or reserved for payment
               shall be repaid to CNS. If CNS deposits funds in trust, payment
               shall be made no later than the occurrence of a Change in
               Control. If and to the extent there are not amounts in trust
               sufficient to pay Employee under this Agreement, CNS shall remain
               liable for any and all payments due to Employee. In accordance
               with the terms of such trust, at all times during the term of
               this Agreement, Employee shall have no rights, other than as an
               unsecured general creditor of CNS, to any amounts held in trust
               and all trust assets shall be general assets of CNS and subject
               to the claims of creditors of CNS. Failure of CNS to establish or
               fully fund such trust shall not be deemed a revocation or
               termination of this Agreement by CNS.

          x.   As a condition of receiving the Severance Payment and other
               benefits provided in this subparagraph 8.f and in subparagraph
               8.g, Employee shall be required to sign a standard release
               agreement with CNS in which he agrees to release any and all
               claims and causes of action which he might have against CNS and
               in which he affirms and acknowledges his obligations under
               paragraphs 9, 10, 11 and 12 of this Agreement.

     g.   Stock Options. Employee shall, immediately upon a Change in Control,
          vest in all stock options which have been granted to him and he shall
          be entitled to exercise all rights and to receive all benefits
          accruing to him under any and all CNS stock purchase and stock option
          plans or programs, including the CNS, Inc. 1994 Amended Stock Plan, or
          any successor to any such plan or program, which shall be in addition
          to and not reduced by any other amounts payable to Employee under this
          paragraph 8.

9.   Confidential Information. All knowledge and information not already
     available to the public which Employee may acquire or has acquired with
     respect to product development, improvements, modifications, discoveries,
     designs, methods, systems, computer software, programs, codes and
     documentation, research, designs, formulas, instructions, methods,
     inventions, trade secrets, services or other private or confidential
     matters of CNS (such as those concerning sales, costs, profits,
     organizations, customer lists, pricing methods, etc.), or of any third
     party which CNS is obligated to keep confidential, shall be regarded by
     Employee as strictly confidential and shall not be used by Employee
     directly or indirectly or disclosed to any persons, corporations or firms.
     All of the foregoing knowledge and information are collectively termed
     "Confidential Information" herein. Employee's obligations under this
     paragraph will not apply to any information which (a) is or becomes known
     to the general public under circumstances involving no breach by Employee
     of the terms of this paragraph, (b) is generally disclosed to third parties
     by CNS as a continuing practice without restriction on such third parties,
     (c) is approved for release by written authorization of CNS's Board, or (d)
     Employee is obligated by law to disclose.

10.  Disclosure and Transfer of Product Developments, etc.

     a.   Employee will make full and prompt disclosure to CNS or all product
          developments, improvements, modifications, discoveries, computer
          software, programs, codes and documentation, research, designs,
          formulas, configurations, instructions, methods and inventions (all of
          which are collectively termed "Developments" herein), whether
          patentable or not, made, discovered, conceived or first reduced to
          practice by Employee or under his direction during his employment,
          alone or with others, whether or not made or conceived during normal
          working hours or on the premises of CNS which relate in any material
          way to the business or to research or development work of CNS.
          Employee confirms by his acceptance of this Agreement that CNS owns
          and shall own all of the Developments.






EXECUTIVE EMPLOYMENT AGREEMENT
PAGE 11


     b.   Employee also agrees on behalf of himself and his heirs and legal
          representatives that he will promptly communicate, disclose and
          transfer to CNS, free of encumbrances and restrictions, all of his
          right, title and interest in the Developments covered by subparagraph
          10.a. and any patents or patent applications covering such
          Developments and to execute and deliver such assignments, patents and
          applications, and any other documents as CNS may direct, and to
          cooperate fully with CNS to enable it to secure any patents or
          otherwise protect such Developments in any and all countries. Employee
          shall assign to CNS any and all copyrights and reproduction rights to
          all material prepared by Employee in connection with his employment.

     c.   Notwithstanding subparagraphs 10.a. and b., however, this paragraph 10
          shall not apply to Developments for which no equipment, supplies,
          facility or trade secret information of CNS was used and which was
          developed entirely on the Employee's own time, and (1) which do not
          relate (a) directly to the business of CNS or (b) to CNS's actual or
          demonstrably anticipated research or development, or (2) which does
          not result from any work performed by Employee for CNS.

     This will confirm that Employee's obligations to CNS under paragraphs 9, 10
     and 11 will continue after the termination of Employee's employment.

11.  Non-Competition. During the term of Employee's employment by CNS and for
     twelve (12) months thereafter, Employee shall not directly or indirectly
     engage in, enter into or participate in the business of CNS or in any
     business or commercial activity which does or is reasonably likely to
     compete with or adversely affect the Business or products of CNS, either as
     an individual for Employee's own account, as a partner or a joint venturer,
     or as an officer, director, consultant or holder of more than five percent
     (5%) of the entity interest in, any other person, firm, partnership or
     corporation, or an employee, agent or salesman for any person. In addition,
     during such period Employee shall not: avail himself of any advantages or
     acquaintances he has made with any person who has, within the twelve (12)
     month period ended on the date of termination of his employment, been a
     customer of CNS or its affiliates, and which would, directly or indirectly,
     materially divert business from or materially and adversely affect the
     Business of CNS; interfere with the contractual relations between CNS and
     any of its employees; or employ or cause to be employed in any capacity or
     retain or cause to be retained as a consultant any person who was employed
     in any capacity by CNS during the twelve (12) month period ended on the
     date of termination of Employee's employment.

     For purposes of this Agreement, the "Business of CNS" or "Business" means
     and includes the business of the manufacture, production, sale, marketing
     and distribution of the Breathe Right strip and any other products
     currently offered or currently under development by CNS or offered or
     currently under development by CNS during one (1) year prior to the date of
     termination of Employee's employment.






EXECUTIVE EMPLOYMENT AGREEMENT
PAGE 12


     Inasmuch as the activities of CNS are conducted on an international basis,
     the restrictions of this paragraph 11 shall apply throughout the United
     States, Canada, Japan and Europe.

12.  Non-Solicitation. During the term of Employee's employment by CNS and for
     twelve (12) months thereafter, Employee shall not directly or indirectly
     solicit any current or prospective CNS customer, broker, vendor or
     distributor for the purpose of providing products or services for or on
     behalf of said customer, broker, vendor or distributor which are
     competitive with the products or services being provided by CNS, which are
     in the development stages of being competitive with the products or
     services being provided by CNS, or which would in any way cause said
     customer, broker, vendor or distributor to discontinue or reduce its
     business relationship with CNS. Current CNS customers, brokers, vendors or
     distributors include those customer, brokers, vendors or distributors with
     whom CNS has had a business relationship at any time within one year
     immediately preceding Employee's termination date. Prospective CNS
     customers, brokers, vendors and distributors include those with whom (a) a
     CNS representative has been in direct personal contact and (b) CNS has a
     reasonable opportunity of entering into a business relationship within six
     months following Employee's termination date. Employee also agrees that
     during his employment in the one year period following his employment, he
     will not directly or indirectly solicit any CNS employees to terminate his
     or her employment with CNS. This Employee non-solicitation obligation
     applies to Employees of CNS during Employee's employment and as of his
     termination date.

13.  Remedies. Employee acknowledges that the restrictions set forth in
     paragraphs 9, 10, 11 and 12 hereof are reasonably necessary to protect
     legitimate business interests of CNS. It is understood that if Employee
     violates his obligations under any of these paragraphs, CNS would suffer
     irreparable harm for which a recovery of money damages would be an
     incomplete and inadequate remedy. It is therefore agreed that CNS, in
     addition to any remedies at law, shall be entitled, as a matter of right,
     in any court of competent jurisdiction, to a mandatory injunction
     restraining Employee pending litigation, as well as upon final
     determination thereof, from violating this Agreement. In addition, CNS will
     discontinue payment to Employee of any Severance or Salary Continuation
     Payments, benefits or bonus which he may be entitled to receive or is
     receiving under paragraphs 6, 7 or 8 hereunder or otherwise, in the event
     of his violation of any of his obligations under this Agreement. In the
     event of cessation of payments and benefits, Employee's release of his
     claims against CNS shall remain valid and fully enforceable in
     consideration of the benefits which Employee received prior to set breach.

14.  Severability. The parties intend that the covenants and agreements
     contained herein shall be deemed to be a series of separate covenants and
     agreements, one for each and every state of the United States and political
     subdivision outside the United States where the business described is
     conducted. If, in any judicial proceeding, a court shall refuse to enforce
     any of the separate covenants deemed included in such action, then such
     unenforceable covenants shall be deemed eliminated from the provisions of
     this Agreement for the purpose of such proceeding to the extent necessary
     to permit the remaining covenants to be enforced in such proceeding.
     Further, in the event that any






EXECUTIVE EMPLOYMENT AGREEMENT
PAGE 13


     provision is held to be overbroad as written, such provision shall be
     deemed amended to narrow its application to the extent necessary to make
     the provision enforceable according to applicable law and enforced as
     amended

15.  Binding Effect.

     a.   CNS will require any successor (whether direct or indirect, by
          purchase, merger, consolidation or otherwise) to all or substantially
          all of the business and/or assets as defined in subparagraph 8.a of
          CNS to expressly assume and agree to perform this Agreement in the
          same manner and to the same extent that CNS would be required to
          perform it if no such succession had taken place, in which case, the
          term "CNS" as used in this Agreement shall instead refer to CNS'
          successor. Failure of CNS to obtain such assumption and agreement
          prior to the effectiveness of any such succession shall be a breach of
          this Agreement and shall entitle Employee to compensation from CNS in
          the same amount and on the same terms as he would be entitled
          hereunder if he terminated his employment for Good Reason following a
          Change in Control, except that for purposes of implementing the
          foregoing, the date on which any such succession becomes effective
          shall be deemed the Date of Termination.

     b.   This Agreement shall inure to the benefit of and be enforceable by
          Employee's personal or legal representatives, successors, heirs, and
          designated beneficiaries. If Employee should die while any amount
          would still be payable to Employee hereunder if Employee had continued
          to live, all such amounts, unless otherwise provided herein, shall be
          paid in accordance with the terms of this Agreement to Employee's
          designated beneficiaries, or, if there is no such designated
          beneficiary, to Employee's estate.

16.  Entire Agreement. From and after the date of this Agreement the terms and
     provisions of this Agreement constitute the entire agreement between the
     parties and this Agreement supersedes any previous oral or written
     communications, representations, or agreements with respect to any subject,
     including the subject matter of compensation, bonus, participation and
     profit sharing and termination compensation.

17.  Waiver and Interpretation. The waiver by either party of a breach of any
     provision of this Agreement by the other party shall not operate or be
     construed as a waiver of any subsequent breach by the breaching party. No
     waiver shall be valid unless in writing and signed by the party providing
     such waiver. If any provision of this Agreement is held by any court to be
     unenforceable, then such provision shall be deemed to be eliminated from
     the Agreement to permit enforceability of the remaining provisions. If any
     provision is held to be overbroad, such provision shall be amended to
     narrow its application to the extent necessary for enforceability. For
     purposes of the release agreement which Employee shall be required to
     execute as a condition of receiving any payments and benefits hereunder,
     "CNS", as referred to in this Agreement, shall include CNS and all its






EXECUTIVE EMPLOYMENT AGREEMENT
PAGE 14


     affiliates, shareholders, officers, directors, employees, agents,
     attorneys, insurers and indemnitors.

18.  Applicable Law. All questions pertaining to the validity, construction,
     execution and performance of this Agreement shall be construed and governed
     in accordance with the laws of the State of Minnesota. The parties consent
     to the personal jurisdiction of the State of Minnesota, waive any argument
     that such a forum is not convenient, and agree that any litigation relating
     to this Agreement shall be venued in Minneapolis, Minnesota.

19.  Tax Withholding. CNS may withhold from any payment of benefits under this
     Agreement (and forward to the appropriate taxing authority) any taxes
     required to be withheld under applicable law.

20.  Notice. Any notice required or desired to be given under this Agreement
     shall be deemed given if in writing sent by certified mail to his residence
     in the case of Employee, or to its principal office in the case of CNS.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and
year first set forth above.
