Dear Mr. Jahnke:

Agreement"). As a result of the Merger, Medical Graphics will become a wholly
owned subsidiary of the Company. In connection with the Merger each of us
desires to enter into a new employment agreement with the Company that would

<PAGE>


          (i) By your resignation upon 30 days prior written notice to the
     Company.

          (ii) By the Company for Cause (as defined in this Agreement)
     immediately upon written notice to you.

          (iii) By the Company for any reason and at any time upon 30 days prior

          (iv) By the Company at any time in the event of your Disability (as

In the event of your termination of employment for any of the foregoing reasons,
you shall immediately resign as a director of the Company and any of its

     (c) DEATH. This Agreement will automatically terminate upon your death.

7.   CONSEQUENCES OF TERMINATION.

     (a) TERMINATION FOR CAUSE; RESIGNATION PRIOR TO CHANGE IN CONTROL OR
         MORE THAN 24 MONTHS AFTER CHANGE IN CONTROL. If your employment is
         terminated at any time by the Company for Cause or if you resign
         prior to a Change in Control (as defined in the separate
         Change-in-Control Agreement attached hereto (the "Change-in-Control
         Agreement")) or more than 24 months after a Change in Control, then
         you will be paid your base salary to the date of termination and the
         unpaid portion of any bonus or incentive amount earned by you for
         the fiscal year ending prior to the termination of your employment
         which you are entitled to receive under the terms of the annual
         incentive plan. You will not be entitled to receive any base salary
         or fringe benefits for any period after the date of termination,
         except for the right to receive benefits which have become vested
         under any benefit plan or to which you are entitled as a matter of
         law.

     (b) TERMINATION WITHOUT CAUSE PRIOR TO CHANGE IN CONTROL OR MORE THAN 24
         MONTHS AFTER CHANGE IN CONTROL. If the Company terminates your
         employment without Cause prior to a Change in Control or more than 24
         months after a Change in Control, then:

         (i)   The Company will pay you a lump sum equal to 18 months of your
               current base salary, less applicable tax withholdings; and

         (ii)  The Company will pay the unpaid portion of any bonus or
               incentive amount earned by you for the fiscal year


<PAGE>

               ending prior to the termination of your employment which you are
               entitled to receive under the terms of the applicable incentive
               plan; and

         (iii) You will be entitled to continued participation in the health
               care coverage, and life insurance benefit plans of the
               Company, as in effect on the date of your termination as
               permitted by law. The Company will continue to pay its share
               of the health care and life insurance premiums for this
               coverage for a period of up to 18 months, and YOU SHALL PAY
               YOUR SHARE OF THE COST ASSOCIATED WITH THAT coverage as if
               you were still actively employed by the Company. If you
               cannot be covered under any of the Company's group plans or
               policies, the Company will reimburse you for your full cost
               of obtaining comparable alternative or individual coverage
               elsewhere, less any contribution that you would have been
               required to make under the Company's group plans or policies.
               If, during the aforesaid 18-month period, you are employed by
               a third party and become eligible for any health care and/or
               life insurance coverage provided by that third party, the
               Company will not, thereafter, be obligated to provide you
               with the insurance benefits described in this paragraph
               (b)(iii). This 18-month coverage shall run concurrently with
               COBRA and thereafter you shall be responsible for the full
               cost of any coverage thereafter.

     (c) TERMINATION IN THE EVENT OF DEATH OR DISABILITY. If your employment
         terminates due to your death or if the Company terminates your
         employment due to a Disability, then

         (i)  The Company will continue to pay your base salary to your estate
              or to you for the remainder of the month in which your death
              occurs or in which your employment is terminated due to
              Disability, together with the unpaid portion of any bonus or
              incentive amount earned by you for the fiscal year ending prior
              to the termination of your employment which you are entitled to
              receive under the terms of the applicable incentive plan; and in
              the event of termination due to Disability, you will continue to
              receive, during that month, all of the fringe benefits then being
              paid or provided to you;

         (ii) You will be entitled to receive all Disability and other
              benefits, such as continued health coverage or life


<PAGE>


              insurance proceeds, provided in accordance with the terms and
              conditions of the health care coverage, life insurance,
              disability, or other employee benefit plans of the Company and
              applicable law.

     (d) TERMINATION WITHIN 24 MONTHS AFTER CHANGE IN CONTROL. If, within 24
         months after a Change in Control, your employment terminates, your
         rights shall be governed by the Change-in-Control Agreement attached
         hereto and executed concurrently herewith.

     (e) The benefits provided you under this Section 7 or in the
         Change-in-Control Agreement are in lieu of any benefits that would
         otherwise be provided to you under any severance pay or other policies
         of the Company.

     8.  NO MITIGATION. Following termination of your employment for any reason
you will be under no obligation to mitigate your damages by seeking other
employment, and there will be no offset against the amounts due you under
Section 7, except as specifically provided in Section 7(b)(iii) or for any
claims which the Company may have against you.

     9.  PROPERTY RIGHTS, CONFIDENTIALITY, NON-SOLICIT AND NON-COMPETE
PROVISIONS.

     (a) COMPANY'S PROPERTY.

         (i) You shall promptly disclose to the Company in writing all
     inventions, discoveries, and works of authorship, whether or not patentable
     or copyrightable, which are conceived, made, discovered, written, or
     created by you alone or jointly with another person, group, or entity,
     whether during the normal hours of employment at the Company or on your own
     time, during the term of this Agreement. You agree to assign all rights to
     all such inventions and works of authorship to the Company. You further
     agree to give the Company any of the assistance it reasonably requires in
     order for the Company to perfect, protect and use its rights to inventions
     and works of authorship.

         This provision shall not apply to an invention, discovery, or work of
     authorship for which no equipment, supplies, facility, or trade secret
     information of the Company was used and which was developed entirely on
     your own time and which does not relate to the business of the Company, to
     the Company's anticipated research or developments, or does not result from
     any work performed by you for the Company.

         (ii) You shall not remove any records, documents, or any other
     tangible items (excluding your personal property) from the premises of the


<PAGE>


     Company in either original or duplicate form, except as is needed in the
     ordinary course of conducting business for the Company.

          (iii) You shall immediately deliver to the Company, upon termination
     of employment with the Company, or at any other time upon the Company's
     request, any property, records, documents, and other tangible items
     (excluding your personal property) in your possession or control, including
     data incorporated in word processing, computer, and other data storage
     media, and all copies of such records, documents, and information,
     including all Confidential Information, as defined below.

     (b) CONFIDENTIAL INFORMATION. During the course of your employment you will
develop, become aware of, and accumulate expertise, knowledge, and information
regarding the Company's and its subsidiaries' organization strategies, business,
and operations and their past, current, or potential customers, and suppliers.
The Company considers such expertise, knowledge, and information to be valuable,
confidential, and proprietary, and it shall be considered Confidential
Information for purposes of this Agreement. During this Agreement and at all
times thereafter you will agree not to use such Confidential Information or
disclose it to other persons or entities except as is necessary for the
performance of your duties for the Company or as has been expressly permitted in
writing by the Company. Provided, however, that the foregoing covenant shall not
apply to any information possessed by you prior to your employment by the
Company, or to any information which is in or has entered the pubic domain or
has been disclosed with any industry segment in which the Company or any
subsidiary or affiliated company of the Company operates by or pursuant to the
authority of the Company or any subsidiary or affiliated company of the Company.

     (c)  NON-SOLICITATION. During (i) the term of this Agreement, and (ii) the
greater of (A) any period for which you are receiving payments under Section 7
of this Agreement, or (B) one year after the termination of this Agreement or
the date on which you are no longer employed by the Company in any capacity,
whichever shall last occur, you shall not directly or indirectly attempt to hire
away any then-current employee of the Company or any subsidiary or to persuade
any such employee to leave employment with the Company or any subsidiary.

     (d)  NON-COMPETITION. During (i) the term of this Agreement and (ii) the
greater of (A) any period for which you are receiving payments under Section 7
of this Agreement, or (B) one year after termination of this Agreement or the
date on which you are no longer employed by the Company in any capacity,
whichever shall last occur, you shall not engage or participate, either
individually or as an employee, consultant, or principal, partner, agent,
trustee, officer, or director of a corporation, partnership, or other business
entity, in any business in which the Company or any subsidiary of the Company
has a more than 20 percent equity interest, was engaged prior to the termination
of this Agreement. Provided, however, that mere ownership of not more than 5% of
the outstanding common stock of a company the securities of which are publicly
traded shall not constitute competition for purposes of this Section 9(d).


<PAGE>


         The provisions of this Section 9 shall survive the termination of this
Agreement.

     10.  ARBITRATION. Any disputes arising under or in connection with this
Agreement (including without limitation the making of this Agreement) shall be
resolved by final and binding arbitration to be held in Minneapolis, Minnesota
in accordance with the rules and procedures of the American Arbitration
Association. The parties shall select a mutually agreeable single arbitrator to
resolve the dispute or if they fail or are unable to do so, each side shall
within the following ten (10) business days select a single arbitrator and the
two so selected shall select a third arbitrator within the following ten (10)
business days. The arbitration award or other resolution may be entered as a
judgment at the request of the prevailing party by any court of competent
jurisdiction in Minnesota or elsewhere. The arbitrator shall have no power to
award any punitive or exemplary damages. The arbitrator may construe or
interpret, but shall not ignore or vary the terms of this Agreement, and shall
be bound by controlling law. You acknowledge that your failure to comply with
the terms of the Agreement regarding Confidential Information, Inventions, and
Non-Competition could cause immediate and irreparable injury to the Company and
that therefore, the arbitrators, or a court of competent jurisdiction, if an
arbitration panel cannot immediately be convened, will be empowered to provide
injunctive relief, including temporary or preliminary relief, to restrain any
such failure to comply. Each party shall bear its own costs and attorneys' fees
in connection with the arbitration.

     11.  DEFINITIONS. For purposes of this Agreement, the following terms will
have the meanings set forth below:

     (a)  CAUSE. "Cause" has the meaning given to it in the Change-in-Control
Agreement.

     (b)  DISABILITY. "Disability" means that you are deemed to be disabled
under the terms of the Company's long term disability plan and have satisfied
the qualifying period for entitlement to benefits under such plan.

     12.  GENERAL PROVISIONS.

     (a)  This Agreement may not be amended or modified except by a written
          agreement signed by both of us.

     (b)  In the event that any provision or portion of this agreement is
          determined to be invalid or unenforceable for any reason, the
          remaining provisions of this Agreement will remain in full force and
          effect to the fullest extent permitted by law.

     (c)  This Agreement shall bind and benefit the parties hereto and their
          respective successors and assigns, but none of your rights or
          obligations hereunder may be assigned by either party hereto without
          the written consent of the other, except by operation of law upon your
          death.

<PAGE>


     (d)  This Agreement has been made in and shall be governed and construed in
          accordance with the laws of the State of Minnesota without giving
          effect to the principles of conflict of laws of any jurisdiction.

     (e)  No failure on the part of either party to exercise, and no delay in
          exercising, any right or remedy under this Agreement will operate as a
          waiver; nor will any single or partial exercise of any right or remedy
          preclude any other or further exercise of any right or remedy.

     (f)  Any notice or other communication under this Agreement must be in
          writing and will be deemed given when delivered in person, by
          overnight courier (with receipt confirmed), by facsimile transmission
          (with receipt confirmed by telephone or by automatic transmission
          report), or upon receipt if sent by certified mail, return receipt
          requested, as follows (or to such other persons and/or addresses as
          may be specified by written notice to the other party):

                           If to Angeion Corporation.:

                           Angeion Corporation
                           Attention:  Chairman of the Board of Directors
                           350 Oak Grove Parkway
                           St. Paul, MN 55127

     (g)  This Agreement, the Change-in-Control Agreement and the stock awards
          and stock option agreements ancillary hereto, contains our entire
          understanding and agreement with respect to these matters and
          supersedes all previous agreements, discussions, or understandings,
          whether written or oral, between or on the same subjects.

     (h)  In the event any provision of this Agreement is held unenforceable,
          that provision will be severed and shall not affect the validity or
          enforceability of the remaining provisions. In the event any provision
          is held to be overbroad, that provision shall be deemed amended to
          narrow its application to the extent necessary to render the provision
          enforceable according to applicable law.

     (i)  All terms of this Agreement intended to be observed and performed
          after the termination of this Agreement will survive such termination
          and will continue in full force and effect thereafter, including
          without limitation, Sections 7, 8, 9, 10, 11 and 12.
