                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         Agreement dated as of March 5, 2003, between Computer Network
Technology Corporation, a Minnesota corporation, having a place of business at
6000 Nathan Lane North, Plymouth, MN 55442 (the "Company"), and Thomas G. Hudson
(the "Executive").

                                   WITNESSETH

         WHEREAS, the Executive has assumed duties of a responsible nature to
the benefit of the Company and to the satisfaction of the Board of Directors
(the "Board") of the Company and its Compensation Committee;

         WHEREAS, the Board and its Compensation Committee believes it to be in
the best interests of the Company to enter into this Agreement to assure
Executive's continuing services to the Company including, but not limited to,
under circumstances in which there is a Change of Control (as defined below);

         WHEREAS, the Board and its Compensation Committee believes it is
imperative to diminish the inevitable distraction of the Executive by virtue of
the personal uncertainties and risks created by a pending or threatened Change
of Control and to encourage the Executive's full attention and dedication to the
Company currently and in the event of any threatened or pending Change of
Control, and to provide the Executive with compensation and benefits
arrangements upon a Change of Control which ensure that the compensation and
benefits expectations of the Executive will be satisfied and which are
competitive with those of other corporations; and

         WHEREAS, in order to accomplish all the above objectives, the Board and
its Compensation Committee has authorized the Company to enter into this
Agreement;

         NOW, THEREFORE, in consideration of the mutual promises herein
contained, the Company and the Executive hereby agree as follows:

         1.       CERTAIN DEFINITIONS.

         a Change of Control (as defined in Section 2) occurs. Anything in this
         Agreement to the contrary notwithstanding, if a Change of Control
         occurs and if the Executive's employment with the Company is terminated
         or the Executive ceases to be Chief Executive Officer ("CEO") of the
         Company prior to the date on which the Change of Control occurs, and if
         it is reasonably demonstrated by the Executive that such termination of
         employment or cessation of status as CEO (i) was at the request of a
         third party who has taken steps reasonably calculated to effect the
         Change of Control or (ii) otherwise arose in connection with or
         anticipation of the Change of Control, then for all purposes of this
         Agreement the

                                       1

         automatically extended so as to terminate on the earlier of (x) three
         years from such Renewal Date or (y) the Executive's Normal Retirement
         Date, unless at least 90 days prior to the Renewal Date the Company
         shall give notice to the Executive that the Employment Period shall not
         be so extended; and provided, further, that upon the occurrence of a
         Change of Control Date, the Employment Period shall automatically be
         extended so as to terminate on the earlier to occur of (1) the third
         anniversary of such date or (2) the Executive's Normal Retirement Date.

         same proportions as their ownership, immediately prior to such
         reorganization, merger or consolidation of the Outstanding Company
         Common Stock and the Outstanding Company Voting Securities, as the case
         may be; or

         liquidation or dissolution of Company or (ii) the sale or other
         disposition of all or substantially all of the assets of the Company,

         Securities, as the case may be.

                           (i)      Base Salary. During the Employment Period,

<PAGE>

                  $350,000, and (y) from and after May 1, 2003, at an annual
                  rate of $367,500 and during each succeeding 12 month period
                  ending April 30, at a rate not less than his base salary in
                  effect on the last day of the preceding 12-month period ending

                  between the Compensation Committee of the Board of Directors
                  and Executive (in the event no agreement is reached, Base
                  Salary shall remain unchanged). Any increase in base salary
                  shall not serve to limit or reduce any other obligation to the
                  Executive under this Agreement. Base Salary shall not be
                  reduced after any such increase except in connection with
                  Company wide reductions applied to other senior executives of
                  the Company. Base salary under Section 4(b)(i) shall
                  hereinafter be referred to as the "Base Salary."

                           (ii)     Additional Compensation. In addition to Base
                  Salary, the Executive shall be participate in the Company's
                  Success Share Bonus Arrangement under terms and conditions
                  determined each year by the Compensation Committee of the
                  Board of Directors of the Company (which, currently is a 65%
                  incentive opportunity and beginning May 1, 2003, shall be a
                  100% incentive opportunity for the applicable year).

                           (iii)    Fringe Benefits. While Executive is employed
                  by the Company under this Agreement, the Company shall provide
                  Executive such insurance and other benefits as are provided
                  from time to time by the Company to its other executives, in
                  accordance with the Company's benefits practices then in
                  effect.

         5.       TERMINATION.

                  (a)      Death or Disability. This Agreement shall terminate
         automatically upon the Executive's death. If the Company determines in
         good faith that the Disability of the Executive has occurred (pursuant
         to the definition of "Disability" set forth below), it may give to the
         Executive written notice of its intention to terminate the Executive's
         employment hereunder. In such event, the Executive's employment with
         the Company shall terminate effective on the 90th day after receipt by
         the Executive of such notice given at any time after a period of six
         consecutive months of Disability and while such Disability is
         continuing (the "Disability Effective Date"), provided that, within the
         90 days after such receipt, the Executive shall not have returned to
         full-time performance of the Executive's duties. For purposes of this
         Agreement, "Disability" means disability which, at least six months
         after its commencement, is determined to be total and permanent by a
         physician selected by the Company or its insurers and acceptable to the
         Executive or the Executive's legal representative (such agreement as to
         acceptability not to be withheld unreasonably). During such six month
         period and until the Disability Effective Date, Executive shall be
         entitled to all compensation provided for under Section 4 hereof.

                  (b)      Cause. During the Employment Period, the Company may
         terminate the Executive's employment with the Company for "Cause." For
         purposes of this Agreement, "Cause" means (i) an act or acts of
         personal dishonesty taken by the Executive and intended to result in
         substantial personal enrichment of the Executive at the expense of the
         Company, (ii) repeated violations by the Executive of the Executive's
         obligations under Section 4(a) of this Agreement which are demonstrably
         willful and deliberate on the Executive's part and which are not
         remedied in a reasonable period of time after receipt of written notice
         from the Company or (iii) the conviction of the Executive of a felony.

                  (c)      Good Reason. During the Employment Period, the
         Executive's employment hereunder may be terminated by the Executive for
         Good Reason. For purposes of this Agreement, "Good Reason" means:

                           (i)      the assignment to the Executive of any
                  duties inconsistent in any respect with Executive's position
                  (including status, offices, titles and reporting
                  relationships), authority, duties or responsibilities as
                  contemplated by Section 4(a)(i) or (ii) of this Agreement
                  (including, without limitation, failure to nominate the
                  Executive to the Board or Executive ceasing to be the Chief
                  Executive Officer of the Company), or any other action by the
                  Company which results in a diminution in such position,
                  authority, duties or responsibilities;

                           (ii)     the failure by the Company to appoint the
                  Executive to the position of CEO or any other action by the
                  Company which results in the diminution of the Executive's
                  position, authority, duties, or responsibilities;

                           (iii)    (x) any failure by the Company to comply
                  with any of the provisions of Section 4(b) of this Agreement
                  or (y) after the Change of Control Date, any failure of the
                  Company to pay Base Salary in accordance with Section 4(b)(i)
                  or failure to pay Additional Compensation on a basis
                  comparable (with respect to targets and incentive opportunity)
                  to that applicable to the Executive with respect to the year
                  immediately preceding the year in which the Change in Control
                  occurs;

                           (iv)     the Company requiring the Executive to be
                  based at any office or location other than that described in
                  Sections 4(a)(i)(B) or 4(a)(ii)(B) hereof, except for travel
                  reasonably required in the performance of the Executive's
                  responsibilities;

                           (v)      any purported termination by the Company of
                  the Executive's employment otherwise than as expressly
                  permitted by this Agreement; or

                           (vi)     any failure by the Company to comply with
                  and satisfy Section 12(c) of this Agreement.

                  Prior to giving a Notice of Termination for Good Reason,
         Executive shall notify the Company within 30 days of action the Company
         has taken in such 30 day period, together with any other similar
         actions within the prior six months, which Executive believes
         constitutes Good Reason. The Company shall have 30 days to cure such
         circumstances, and if not cured to the reasonable satisfaction of the
         Executive, then Executive may give such Notice of Termination for Good
         Reason.

                  (d)      Notice of Termination. Any termination of the
         Executive's employment hereunder by the Company for Cause or by the
         Executive for Good Reason shall be communicated by Notice of
         Termination to such other party hereto given in accordance with Section
         14(b) of this Agreement. For purposes of this Agreement, a "Notice of
         Termination" means a written notice which (i) indicates the specific
         termination provision in this Agreement relied upon, (ii) sets forth in

         basis for termination of the Executive's employment under the provision
         so indicated and (iii) if the Date of Termination (as defined below) is
         other than the date of receipt of such notice, specifies the
         termination date (which date shall be not more than fifteen (15) days
         after the giving of such notice). Further, a Notice of Termination for
         Cause is required to include a copy of a resolution duly adopted by the
         affirmative vote of not less than three-quarters (3/4) of the entire
         membership of the Board (excluding the Executive) at a meeting of the
         Board which was called and held for the purpose of considering such
         termination (after reasonable notice to the Executive and an
         opportunity for the Executive, together with the Executive's counsel,
         to be heard before the Board) finding that, in the good faith opinion
         of the Board, the Executive was guilty of conduct set forth in the
         definition of Cause herein, and specifying the particulars thereof in
         detail.

                  (e)      Date of Termination. "Date of Termination" means the
         date of receipt of the Notice of Termination or any later date
         specified therein, as the case may be; provided, however, that (i) if
         the Executive's employment hereunder is terminated by the Company other
         than for Cause or Disability, the Date of Termination shall be the date
         on which the Company notifies the Executive of such termination and
         (ii) if the Executive's employment hereunder is terminated by reason of
         death or Disability, the Date of Termination shall be the date of death
         of the Executive or the Disability Effective Date, as the case may be.

         6.       OBLIGATIONS OF THE COMPANY UPON TERMINATION.

                  (a)      Death. If the Executive's employment hereunder is
         terminated by reason of the Executive's death, this Agreement shall
         terminate without further obligations to the Executive's legal
         representatives under this Agreement, other than those obligations
         accrued or earned and vested (if applicable) by the Executive as of the
         Date of Termination, including, for this purpose (i) the Executive's
         full Base Salary through the Date of Termination at the rate in effect
         on the Date of Termination, disregarding any reduction in Base Salary
         in violation of this Agreement (the "Highest Base Salary") and (ii) any
         compensation previously deferred by the Executive (together with any
         accrued

                                       7

         interest thereon) and not yet paid by the Company in accordance with
         the applicable plan (to the extent vested) and any accrued vacation pay
         not yet paid by the Company (such amounts specified in clauses (i) and
         (ii) are hereinafter referred to as "Accrued Obligations"). All such
         Accrued Obligations shall be paid to the Executive's estate or
         beneficiary, as applicable, in a lump sum in cash within 30 days of the
         Date of Termination. Anything in this Agreement to the contrary
         notwithstanding, the Executive's family shall be entitled to receive
         benefits at least equal to the most favorable benefits provided by the
         Company and any of its subsidiaries to surviving families of employees
         of the Company and such subsidiaries under such plans, programs,
         practices and policies relating to family death benefits, if any, in
         accordance with the most favorable plans, programs, practices and
         policies of the Company and its subsidiaries in effect on the date of
         the Executive's death with respect to other key employees of the
         Company and its subsidiaries and their families.

                  (b)      Disability. If the Executive's employment is
         terminated by reason of the Executive's Disability, this Agreement
         shall terminate without further obligations to the Executive, other
         than those obligations accrued or earned and vested (if applicable) by
         the Executive as of the Date of Termination, including for this
         purpose, all Accrued Obligations. All such Accrued Obligations shall be
         paid to the Executive in a lump sum in cash within 30 days of the Date
         of Termination. Anything in this Agreement to the contrary
         notwithstanding, the Executive shall be entitled after the Disability
         Effective Date to receive disability and other benefits at least equal
         to the most favorable of those provided by the Company and its
         subsidiaries to disabled employees and/or their families in accordance
         with such plans, programs, practices and policies relating to
         disability, if any, in accordance with the most favorable plans,
         programs, practices and policies of the Company and its subsidiaries in
         effect on or after the Effective Date or, if more favorable to the
         Executive and /or the Executive's family, as in effect at any time
         thereafter with respect to other key employees of the Company and its
         subsidiaries and their families.

                  (c)      Cause; Other than for Good Reason. If the Executive's
         employment shall be terminated for Cause, this Agreement shall
         terminate without further obligations to the Executive other than those
         obligations accrued or earned and vested (if applicable) by the
         Executive as of the Date of Termination, including for this purpose all
         Accrued Obligations. If the Executive terminates employment other than
         for Good Reason, this Agreement shall terminate without further
         obligations to the Executive, other than those obligations accrued or
         earned and vested (if applicable) by the Executive through the Date of
         Termination, including for this purpose, all Accrued Obligations. All
         such Accrued Obligations shall be paid to the Executive in a lump sum
         in cash within 30 days of the Date of Termination.

                  (d)      Good Reason; Other Than for Cause, Disability or
                           Death.

                           (1)      If, during the Employment Period and prior
                  to a Change of Control the Company shall terminate the
                  Executive's employment hereunder other than

                  terminate his employment hereunder for Good Reason:

                                    occurred; and

                                             C.     (I) in the case of

                                    the Executive with tax planning and
                                    financial counseling services for a period
                                    of three years following the Date of
                                    Termination on the same basis as such
                                    services were provided or made available to
                                    him immediately prior to the Date of
                                    Termination or the Change of Control Date,
                                    whichever is more favorable.

                  (e)      All of Executive's unvested options shall immediately
         vest upon completion of a Change of Control, if at the time of
         completion such options are not substituted or continued by the
         acquiror, regardless of whether Executive's employment is terminated.

         7.       NON-EXCLUSIVITY OF RIGHTS. Nothing in this Agreement shall
prevent or limit the Executive's continuing or future participation in any
benefit, bonus, incentive or other plans, programs, policies or practices,
provided by Company, the Company or any of their respective subsidiaries and for
which the Executive may qualify, nor shall anything herein limit or otherwise
affect such rights as the Executive may have under any stock option, restricted
stock or other agreements with Company, the Company or any of their respective
subsidiaries. Amounts which are vested benefits or which the Executive is
otherwise entitled to receive under any plan, policy, practice or program of
Company, the Company or any of their respective subsidiaries at or subsequent to
the Date of Termination shall be payable in accordance with such plan, policy
practice or program.

         8.       FULL SETTLEMENT. The Company's obligation to make the payments
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others. In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement. The Company
agrees to pay, to the full extent permitted by law, all legal fees and expenses,
as incurred by the Company, the Executive and others, which the Executive may
reasonably incur as a result of any contest (regardless of the

                                       11

<PAGE>

outcome thereof) by the Company or others of the validity or enforceability of,
or liability under, any provision of this Agreement or any guarantee of
performance thereof (including as a result of any contest by the Executive about
the amount of any payment pursuant to Section 9 of this Agreement), plus in each
case interest at the applicable Federal rate provided for in Section 7872(f)(2)
of the Internal Revenue Code of 1986, as amended (the "Code").

         9.       CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY.

                  (a)      Anything in this Agreement to the contrary
         notwithstanding, in the event it shall be determined that any payment
         or distribution by the Company, any individual or entity whose actions
         result in a Change of Control, or their respective subsidiaries or
         affiliates to or for the benefit of the Executive (whether paid or
         payable or distributed or distributable pursuant to the terms of this
         Agreement or otherwise, but determined without regard to any additional
         payments required under this Section 9, including, but not limited to,
         any amounts in respect of (i) options to acquire shares of Company
         common stock and (ii) restricted shares of Company common stock (a
         "Payment"), would be subject to the excise tax imposed by Section 4999
         of the Code or any interest or penalties with respect to such excise
         tax (such excise tax, together with any such interest and penalties,
         are hereinafter collectively referred to as the "Excise Tax"), then the
         Executive shall be entitled to receive an additional payment (a
         "Gross-Up Payment") from the Company in an amount such that after
         payment by the Executive of all taxes (including any interest or
         penalties imposed with respect to such taxes), including, without
         limitation, any income taxes, employment taxes (and any interest and
         penalties imposed with respect thereto) and Excise Tax, imposed upon
         the Gross-Up Payment, the Executive retains, after taking into account
         the phase out of itemized deductions and personal exemptions
         attributable to such Gross-Up Payment, an amount of the Gross-Up
         Payment equal to the Excise Tax imposed upon Payments.

                  (b)      Subject to the provisions of Section 9(c), all
         determinations required to be made under this Section 9, including
         whether a Gross-Up Payment is required and the amount of such Gross-Up
         Payment, shall be made by the firm of independent public accountants
         selected by the Company (which firm shall not audit the Company's
         financial statements) (the "Accounting Firm") which shall provide
         detailed supporting calculations both to the Company and the Executive
         within 30 business days of the Date of Termination, or such earlier
         time as is requested by the Company. In the event that the Accounting
         Firm is serving as accountant or auditor for the individual, entity or
         company effecting the Change of Control, the Executive shall appoint
         another nationally recognized accounting firm to make the
         determinations required hereunder (which accounting firm shall then be
         referred to as the Accounting Firm hereunder). All fees and expenses of
         the Accounting Firm shall be borne solely by the Company. Any Gross- Up
         Payment, as determined pursuant to this Section 9, shall be paid to the
         Executive upon the receipt of the Accounting Firm's determination. If
         the Accounting Firm determines that no Excise Tax is payable by the
         Executive, it shall furnish the Executive with a written opinion that
         failure to report the Excise Tax on the Executive's applicable federal
         income tax return would not result in the imposition of a negligence or
         a similar penalty. Any

                                       12

<PAGE>

         determination by the Accounting Firm shall be binding upon the Company
         and the Executive. As a result of the uncertainty in the application of
         Section 4999 of the Code at the time of the initial determination by
         the Accounting Firm hereunder, it is possible that Gross-up Payments
         which will not have been made by the Company should have been made
         ("Underpayment"), consistent with the calculations required to be made
         hereunder. In the event that the Company exhausts its remedies pursuant
         to Section 9(c) and the Executive thereafter is required to make a
         payment of any Excise Tax, the Accounting Firm shall determine the
         amount of the Underpayment that has occurred and any such Underpayment
         shall be promptly paid by the Company to or for the benefit of the
         Executive.

                  (c)      The Executive shall notify the Company in writing of
         any claim by the Internal Revenue Service that, if successful, would
         require the payment by the Company of the Gross- Up Payment. Such
         notification shall be given as soon as practicable but no later than
         ten business days after the Executive knows of such claim and shall
         apprise the Company of the nature of such claim and the date on which
         such claim is requested to be paid. The Executive shall not pay such
         claim prior to the expiration of the thirty-day period following the
         date on which it gives such notice to the Company (or such shorter
         period ending on the date that any payment of taxes with respect to
         such claim is due). If the Company notifies the Executive in writing
         prior to the expiration of such period that it desires to contest such
         claim, the Executive shall:

                           (i)      give the Company any information reasonably
                  requested by the Company relating to such claim,

                           (ii)     take such action in connection with
                  contesting such claim as the Company shall reasonably request
                  in writing from time to time, including, without limitation,
                  accepting legal representation with respect to such claim by
                  an attorney reasonably selected by the Company,

                           (iii)    cooperate with the Company in good faith in
                  order to effectively contest such claim,

                           (iv)     permit the Company to participate in any
                  proceedings relating to such claim; provided, however, that
                  the Company shall bear and pay directly all costs and expenses
                  (including additional interest and penalties) incurred in
                  connection with such contest and shall indemnify and hold the
                  Executive harmless, on an after-tax basis, for any Excise Tax
                  or income tax, including interest and penalties with respect
                  thereto, imposed as a result of such representation and
                  payment of costs and expenses.

                           Without limitation on the foregoing provisions of
                  this Section 9(c), the Company shall control all proceedings
                  taken in connection with such contest and, at its sole option,
                  may pursue or forgo any and all administrative appeals,
                  proceedings, hearings and conferences with the taxing
                  authority in respect of such

                                       13

<PAGE>

                  claim and may, at its sole option, pay such claim and direct
                  the Executive to sue for a refund or contest the claim in any
                  permissible manner, and the Executive agrees to prosecute such
                  contest to a determination before any administrative tribunal,
                  in a court of initial jurisdiction and in one or more
                  appellate courts, as the Company shall determine; provided,
                  however, that if the Company pays such claim and directs the
                  Executive to sue for a refund, the Company shall indemnify and
                  hold the Executive harmless, on an after-tax basis, from any
                  Excise Tax or income tax, including interest or penalties with
                  respect thereto, imposed with respect to such payment; and
                  further provided that any extension of the statute of
                  limitations relating to payment of taxes for the taxable year
                  of the Executive with respect to which such contested amount
                  is claimed to be due is limited solely to such contested
                  amount. Furthermore, the Company's control of the contest
                  shall be limited to issues with respect to which a Gross-Up
                  Payment would be payable hereunder and the Executive shall be
                  entitled to settle or contest, as the case may be, any other
                  issue raised by the Internal Revenue Service or any other
                  taxing authority.

                  (d)      If, after the receipt by the Executive of an amount
         paid by the Company pursuant to Section 9(c), the Executive becomes
         entitled to receive any refund with respect to such claim, the
         Executive shall (subject to the Company's complying with the
         requirements of Section 9(c)) promptly pay to the Company the amount of
         such refund (together with any interest paid or credited thereon after
         taxes applicable thereto). If, after the receipt by the Executive of an
         amount paid by the Company pursuant to Section 9(c), a determination is
         made that the Executive shall not be entitled to any refund with
         respect to such claim, and the Company does not notify the Executive in
         writing of its intent to contest such denial of refund prior to the
         expiration of thirty days after such determination, then Executive
         shall be under no obligation to repay such amount and the amount of
         such payment shall offset, to the extent thereof, the amount of
         Gross-Up Payment required to be paid.

         10.      CERTAIN COVENANTS OF EXECUTIVE.

                  (a)      As used in Section 10 and Section 11, the Company
         shall include the Company and each corporation, partnership, or other
         entity that controls the Company, is controlled by the Company, or is
         under common control with the Company (in each case "control" meaning
         the direct or indirect ownership of 50% or more of all outstanding
         equity interests).

                  (b)      While Executive is employed by the Company and,
         following the termination of the Executive 's employment for any
         reason, until the first anniversary of the Date of Termination,
         Executive will not, directly or indirectly:

                           (i)      employ or attempt to employ any director,
                  officer, or employee of the Company, or otherwise interfere
                  with or disrupt any employment relationship (contractual or
                  other) of the Company;

                                       14

<PAGE>

                           (ii)     solicit, request, advise, or induce any
                  present or potential customer, supplier, or other business
                  contact of the Company to cancel, curtail, or otherwise change
                  its relationship with the Company; or

                           (iii)    publicly criticize or disparage in any
                  manner or by any means the Company or its management,
                  policies, operations, products, services, practices, or
                  personnel.

                  (c)      Executive hereby acknowledges and agrees that all
         non-public information and data of the Company, including without
         limitation that related to product and service formulation, customers,
         pricing, sales, and financial results (collectively, "Trade Secrets")
         are of substantial value to the Company, provide it with a substantial
         competitive advantage in its business, and are and have been maintained
         in the strictest confidence as trade secrets. Except as permitted by
         the Board, or as appropriate in the performance of Executive's duties
         in the normal course of business, Executive shall not at any time
         disclose or make accessible to anyone any Trade Secrets.

                  (d)      Executive acknowledges and agrees that this Section
         10 and each provision hereof are reasonable and necessary to ensure
         that the Company receives the expected benefits of this Agreement and
         that violation of this Section 10 will harm the Company to such an
         extent that monetary damages alone would be an inadequate remedy.
         Consequently, in the event of any violation or threatened violation by
         Executive of any provision of this Section 10, the Company shall be
         entitled to an injunction (in addition to all other remedies it may
         have) restraining Executive from committing or continuing such
         violation. If any provision or application of this Section 10 is held
         unlawful or unenforceable in any respect, this Section 10 shall be
         revised or applied in a manner that renders it lawful and enforceable
         to the fullest extent possible.

                  (e)      Upon termination of Executive's employment for any
         reason, Executive covenants to resign from the Board effective no later
         than the Termination Date.

                  (f)      Prior to the payment of any amount pursuant to
         Sections 6(d)(1)(i)(B), 6(d)(2)(i)(B) and Section 9, Executive shall
         have executed the release in the form set forth as Exhibit A (with the
         blanks appropriately filled in) and the release shall have become
         irrevocable.

         11.      CREATIONS.

                  (a)      Executive hereby transfers and assigns to the Company
         (or its designee) all right, title, and interest of Executive in and to
         every idea, concept, invention, and improvement (whether patented or
         not) conceived by Executive and all copyrighted or copyrightable matter
         created by Executive that relates to the Company's business
         (collectively, "Creations"). Executive shall communicate promptly and
         disclose to the Company, in such form as the Company may request, all
         information, details, and data

                                       15

<PAGE>

         pertaining to each Creation. Every copyrightable Creation, regardless
         of whether copyright protection is sought or preserved by the Company,
         shall be "work for hire" as defined in 17 U.S.C. Section 101 and the
         Company shall own all rights in and to such matter throughout the
         world, without the payment of any royalty or other consideration to
         Executive or anyone claiming through Executive.

                  (b)      All right, title, and interest in and to any and all
         trademarks, trade names, service marks, and logos adopted, used, or
         considered for use by the Company during Executive's employment
         (whether or not developed by Executive) to identify the Company's
         products or services (collectively, the "Marks") and all other
         materials, ideas, or other property conceived, created, developed,
         adopted, or improved by Executive solely or jointly during Executive's
         employment by the Company and relating to its business, shall be owned
         exclusively by the Company. Executive shall not have, and will not
         claim to have, any right, title, or interest of any kind in or to the
         Marks or such other property.

                  (c)      Executive shall execute and deliver to the Company
         such formal transfers and assignments and such other documents as the
         Company may request to permit the Company (or its designee) to file and
         prosecute such registration applications and other documents it deems
         useful to protect its rights under this Agreement. Any idea,
         copyrightable matter, or other property relating to the Company's
         business and disclosed by Executive prior to the first anniversary of
         the Date of Termination shall be deemed to be governed hereby unless
         proved by Executive to have been first conceived and made after the
         Date of Termination.

                  (d)      Executive acknowledges and understands that this
         Agreement does not apply to any invention that qualifies fully under
         the provisions of Minnesota Statutes Annotated Sections 181.78(1) and
         (2), the text of which is attached as Exhibit B. Employee acknowledges
         this section shall serve as written notice to Employee as required by
         Minnesota Statutes Annotated Section 181.78(3).

         12.      SUCCESSORS.

                  (a)      This Agreement is personal to the Executive and
         without the prior written consent of the Company shall not be
         assignable by the Executive otherwise than by will or the laws of
         descent and distribution. This Agreement shall inure to the benefit of
         and be enforceable by the Executive's legal representatives.

                  (b)      This Agreement shall inure to the benefit of and be
         binding upon Company and the Company and their respective successors
         and assigns.

                  (c)      The Company will require any successor (whether
         direct or indirect, by purchase, merger, consolidation or otherwise) to
         all or substantially all of its business and/or assets to assume
         expressly and agree to perform this Agreement in the same manner and to
         the same extent that the Company would be required to perform it if no

                                       16

<PAGE>

         such succession had taken place. As used in this Agreement, "Company"
         shall mean as hereinbefore defined and any successor to its business
         and/or assets as aforesaid which assumes and agrees to perform this
         Agreement by operation of law, or otherwise.

         13.      ARBITRATION. Any controversy or claim arising out of or
relating to this Agreement, or the breach of this Agreement, other than claims
for specific performance or injunctive relief pursuant to Section 10, shall be
settled by arbitration conducted in Minneapolis, Minnesota in accordance with
the Center for Public Resources Rules for Non-Administered Arbitration of
Business Disputes by a sole arbitrator selected by the parties from the Center
for Public Resources Panels of Distinguished Neutrals. The arbitration shall be
governed by the United States Arbitration Act, 9 U.S.C. Sections 1-16 and
judgment upon any award rendered by the arbitrator may be entered in any
Minnesota state or United States federal court sitting in Minneapolis,
Minnesota. The arbitrator shall not award either damages in excess of actual
damages or attorneys' fees, but may award the prevailing party reasonable costs.
The parties to this Agreement irrevocably submit to the jurisdiction of said
arbitrator and court and agree that all such claims may be heard and determined
only by such arbitrator and that all judgments may be entered in only such
courts.

         14.      MISCELLANEOUS.

                  (a)      This Agreement shall be governed by and construed in
         accordance with the laws of the State of Minnesota, without reference
         to principles of conflict of laws. The captions of this Agreement are
         not part of the provisions hereof and shall have no force or effect.
         This Agreement may not be amended or modified otherwise than by a
         written agreement executed by the parties hereto or their respective
         successors and legal representatives.

                  (b)      All notices and other communications hereunder shall

         WHEREAS, the Company and Executive are parties to that certain Amended

Minnesota Statutes Annotated Section 181.78 provides as follows:

         Subdivision 1. Any provision in an employment agreement that provides
that an employee shall assign or offer to assign any of the employee's rights in
an invention to the employer shall not apply to an invention for which no
equipment, supplies, facility or trade secret information of the employer was
used and that was developed entirely on the employee's own time, and

         (1)      that does not relate (a) directly to the business of the
employer or (b) to the actual or demonstrably anticipated research or
development, or

         (2)      that does not result from any work performed by the employee
for the employer. Any provision that purports to apply to such an invention is
to that extent against the public policy of this state and is to that extent
unenforceable.

         Subdivision 2. No employer shall require a provision made void and
unenforceable by subdivision 1 as a condition of employment or continuing
employment.
