                    The principal officers of Cardiotronics are as
                    follows:

                    President                Ronald R. Bromfield
                                             1809 Sienna Canyon Drive
                                             Encinitas, CA  92024

                    Vice President,          Tim J. Way
                    Quality Assurance        2066 Fairhope Loop
                    And Secretary            Vista, CA  92083

                    Vice President,          Scott P. Youngstrom
                    Finance and Admin.,      208 East Glaucus
                    and Treasurer            Leucadia, CA  92024
                                        
          Item 2.   Ballard Acquisition Corporation ("BAC") is a
                    Colorado corporation.  It was incorporated
                    December 2, 1996.  Its principal business and
                    office address is as follows:

                         Ballard Acquisition Corporation
                         12050 Lone Peak Parkway
                         Draper, Utah  84020

                    BAC is a wholly-owned subsidiary of Ballard  
                    Medical Products, a Utah corporation ("BMP").

                    During the last five years, neither BAC nor BMP
                    has been convicted in any criminal proceeding.

                    During the last five years, neither BAC nor BMP
                    has been a party to any civil proceeding of a
                    judicial or administrative body of competent
                    jurisdiction where as a result of such proceeding
                    either entity became subject to a judgment, decree
                    or final order enjoining future violations of, or
                    prohibiting or mandating activities subject to,
                    federal or state securities laws or finding any
                    violation with respect to such laws. 

          Item 3.   Effective December 10, 1996, BAC entered into
                    Stock Purchase Agreements for the purchase of the
                    shares of capital stock of Cardiotronics shown in
                    the cover page of this Schedule 13D.  The
                    effective purchase price is $3.75 per share of
                    Common Stock or equivalent thereof.

                    The source of funds used and to be used in making
                    the purchases is a capital contribution to BAC by
                    BMP, from BMP's cash reserves.

          Item 4.   The purpose of the acquisition of Cardiotronics'
                    shares by BAC is to acquire eventually 100% of all
                    classes of outstanding shares of Cardiotronics. 
                    BAC intends to convert a sufficient portion of the
                    Cardiotronics convertible preferred stock into
                    common stock, to enable BAC to effect a merger of
                    BAC into Cardiotronics, with Cardiotronics as the
                    surviving corporation pursuant to Section
                    7-111-104 of the Colorado Business Corporation Act
                    (the "Act").  That law allows a parent corporation
                    owning at least 90% of the outstanding shares of
                    each class of a subsidiary corporation to effect
                    such a merger without seeking the approval of the
                    shareholders of the subsidiary corporation (here,
                    Cardiotronics).

                    Also effective December 10, 1996, Cardiotronics
                    entered into a Merger Agreement with BMP and BAC,
                    pursuant to which BAC intends to effect this
                    "short-form" merger within the next 60 days.  This
                    will include the giving to remaining shareholders
                    of Cardiotronics the right to dissent, pursuant to
                    Section 7-113-101, et. seq. of the Act.

                    Immediately following the execution and closing
                    under the Stock Purchase Agreements, certain
                    directors and executive officers of Cardiotronics
                    resigned their positions.  The following directors  
                    resigned:

                         Ronald R. Bromfield
                         Bruno T. Bisceglia, Jr.
                         Richard B. Emmitt
                         Elizabeth H. Weatherman
                         David L. Schlotterbeck

                    BMP and BAC intend to ask the remaining directors,
                    Robert S. Grimes and Tim J. Way to appoint the
                    following replacement directors, to fill the
                    vacancies created by the above-mentioned
                    resignations:

                         Dale H. Ballard
                         Harold R. ("Butch") Wolcott
                         E. Martin Chamberlain, Jr.
                         Kenneth R. Sorenson
                         Paul W. Hess

                    All of these replacement directors are executive
                    officers of BMP.

                    Upon consummation of the merger, it is intended
                    that the  securities of Cardiotronics will be
                    delisted from NASDAQ and that registration of
                    Cardiotronics stock will be terminated.

          Item 5.   BAC owns, beneficially and of record, all of the
                    shares of capital stock of Cardiotronics listed in
                    box 7 of the cover page to this Schedule 13D.  All
                    of said shares were acquired on December 10, 1996. 
                    BMP owns directly no shares of Cardiotronics. 

          Item 6.   BMP and BAC are both parties to the Merger
                    Agreement with Cardiotronics.

          Item 7.   The following exhibits are filed herewith:

                    Exhibit 1           Stock Purchase Agreement

                    Exhibit 2           Stock Purchase Agreement with 
                                        SO-CAL Partners

                    Exhibit 3           Merger Agreement

                                          SIGNATURES

          After reasonable inquiry and to the best of my knowledge and
          belief, I certify that the information set forth in this
          state is true, complete and correct.

                                   STOCK PURCHASE AGREEMENT

               This Stock Purchase Agreement (this "Agreement") is
          made and entered into as of the time on December 10, 1996
          which all parties hereto have executed and delivered this

          selling stockholders (individually, "Seller" or
          collectively, "Sellers"), Ballard Acquisition Corporation, a
          Colorado corporation, all of whose capital stock is owned
          directly by Ballard Medical Products ("Buyer"), and Ballard
          Medical Products, a Utah corporation ("Ballard Medical"),
          with respect to the following facts:

               A.   Sellers own shares of the outstanding common stock

          Buyer is willing to purchase the Shares from each Seller,
          all upon the terms and conditions contained herein.

               NOW, THEREFORE, in consideration of the foregoing

          on Exhibit A, at an effective price of Three Dollars and
          Seventy-Five Cents ($3.75) per share of Common Stock
          (assuming conversion of all shares of Preferred Stock), as

          Price").  The Purchase Price shall be paid to each Seller by
          cashier's check or wire transfer in accordance with the
          schedule set forth on Exhibit A.  Concurrently herewith,
          each Seller shall deliver to Buyer the certificate
          representing the Shares together with a duly executed
          irrevocable stock power with signature guaranteed. 
          Execution of this Agreement by Sellers, Buyer and Ballard

               2.   REPRESENTATIONS AND WARRANTIES OF SELLER.  Each
          Seller, severally and not jointly, hereby represents and
          warrants to Company, Buyer and Ballard Medical that:

                    2.2  The execution and delivery of this Agreement 
          and the performance by Seller of his or its obligations
          hereunder will not conflict with, violate or constitute a

          certificate or articles of incorporation, bylaws or similar

          franchise or permit, order, judgment, writ or decree, which conflict,
          violation or default will, in the case of this clause, have
          a material adverse effect on Company's business, the
          transactions contemplated by the Merger Agreement by and
          among Company, Buyer and Ballard Medical ("Merger
          Agreement") or Seller's ability to perform
          his or its obligations hereunder.

                    2.3  No consent or approval by, notice to or
          registration with, any governmental or administrative
          authority or board or third party is required on the part of
          Seller in connection with the execution and delivery by Seller of 
          this Agreement or the performance by Seller of his or its 
          obligations hereunder, except for consents, approvals, notices or
          registrations that will not individually, or in the 
          aggregate, have a material adverse effect on Company's business, 
          the transactions contemplated by the Merger Agreement or Seller's 
          ability to perform his or its obligations hereunder.

                    2.4  As of the Closing Time, Seller's only
          ownership of, or interest in, Company common stock or
          preferred stock or any other equity securities of Company
          consists solely of the interests described in Exhibit A hereto 
          (the "Securities").  The undersigned has good title to the 
          Securities, and such Securities are owned by the undersigned 
          free and clear of any lien, claim, charge, encumbrance, security 
          interest, title defect or other restriction (other than 
          restrictions on transfer imposed by federal or state securities 
          laws).

                    2.5  To the knowledge of Seller, the Securities
          acquired by Seller from Company were issued and sold to  
          Seller in compliance with the registration requirements of
          the Securities Act of 1933, as amended ("Securities Act"), 
          and applicable state securities laws.  The Securities are
          not subject to any voting trust or voting agreement.

                    2.6  Seller has discussed the tax consequences of
          this Agreement with his or its counsel or tax advisor to the
          extent Seller deemed necessary. 

               3.   REPRESENTATIONS AND WARRANTIES OF BUYER AND
          BALLARD MEDICAL.  Buyer and Ballard Medical hereby represent
          and warrant to each Seller as follows:

                    3.1  Corporate Organization; Due Authorization and
          Validity of Agreement.  Buyer is a corporation duly
          organized, validly existing and in good standing under the
          laws of Colorado, and Ballard Medical is a corporation duly
          organized, validly existing and in good standing under the
          laws of Utah.  Both Buyer and Ballard Medical have all
          requisite corporate power and authority to enter into this
          Agreement and the Merger Agreement and to carry out its
          obligations under this Agreement and the Merger Agreement. 
          The execution and delivery of this Agreement by Buyer and
          Ballard Medical and the performance of the obligations of
          Buyer and Ballard Medical hereunder have been duly
          authorized by all necessary corporate action by the
          respective Board of Directors of Buyer and Ballard Medical,
          and no other corporate proceedings on the part of Buyer or 
          Ballard Medical are necessary to authorize such execution, 
          delivery and performance.  This Agreement has been duly 
          executed by Buyer and Ballard Medical and constitutes their 
          legal, valid and binding obligation, enforceable against Buyer 
          and Ballard Medical in accordance with its terms. 

                    3.2  No Conflict or Violation.  The execution,
          delivery and performance by Buyer and Ballard Medical of
          this Agreement do not and will not violate or conflict with
          any provision of the charter documents or by-laws of Buyer
          or Ballard Medical and do not and will not violate any
          provision of law, or any order, judgment or decree of any
          court or other governmental or regulatory authority, nor
          violate nor will result in a breach of or constitute (with
          due notice or lapse of time or both) a default under any
          contract, lease, loan agreement, mortgage, security
          agreement, trust indenture or other agreement or instrument
          to which Buyer or Ballard Medical is a party or by which 
          it is bound or to which any of its properties or assets is 
          subject, which conflict, violation or default will, in the 
          case of this clause, have a material adverse effect on Buyer's 
          or Ballard Medical's business, the transactions contemplated by the
          Merger Agreement or Buyer's or Ballard Medical's ability to  
          perform their respective obligations hereunder.

                    3.3  Investment Intent.  The Shares will be
          acquired hereunder solely for the account of Buyer for
          investment purposes only and not with a view to or for sale
          in connection with any distribution of the securities of the
          Company and will not be sold or transferred by Buyer except
          in compliance with the Securities Act and applicable state
          law.

               4.   RESIGNATION OF DIRECTORS.  As of the Closing Time,
          each Seller who is a director of the Company shall submit
          his resignation from the board of directors of Company;
          provided, however, that Robert S. Grimes and Tim J. Way shall not
          submit their resignations and shall remain on the board of
          directors.

               5.   FURTHER ASSURANCES.  Each of the parties hereto
          agrees to use its best efforts at its own expense to take,
          or cause to be taken, all action and to do, or cause to be
          done, all things necessary, proper or advisable under applicable 
          laws and regulations to consummate and make effective the
          transactions contemplated by this Agreement. 

               6.   INDEMNIFICATION.  The parties shall indemnify each
          other as set forth below:

                    6.1  Indemnification by Seller.  Each Seller,
          severally and not jointly, shall indemnify, defend and hold
          harmless Buyer, the Company, and Ballard Medical from and
          against all claims, losses, damages, liabilities and
          expenses (including without limitation attorneys' fees,
          settlement costs and any legal or other expenses for
          investigation or defending any actions or threatened
          actions) asserted against, imposed upon or incurred by
          Buyer, the Company, or Ballard Medical in connection with,
          on account of, or as a result of (i) any misrepresentations
          or breach of any of the representations and warranties made
          by such Seller herein, or (ii) the breach of any agreement
          or obligation of such Seller contained herein.

                    6.2  Indemnification by Buyer and Ballard Medical. 
          Buyer and Ballard Medical, jointly and severally, shall
          indemnify, defend and hold harmless each Seller from and
          against all claims, losses, damages, liabilities and
          expenses (including without limitation attorneys' fees,
          settlement costs and any legal or other expenses for
          investigation or defending any actions or threatened
          actions) asserted against, imposed upon or incurred by such
          Seller in connection with, on account of, or as a result of
          (i) any misrepresentations or breach of any of the  
          representations and warranties made by Buyer or Ballard Medical 
          herein, or (ii) the breach of any covenant, agreement or 
          obligation of Buyer or Ballard Medical contained herein.

               7.   LOANS, EMPLOYMENT AND INTERESTS.

                    7.1  Except for the loans set forth on Exhibit B
          hereto ("Loans") and the employment agreements set forth on
          Exhibit C hereto ("Employment Agreement"), neither the
          Company nor any of its subsidiaries is indebted to any
          Seller, and, except for the Loans (and interest accrued in
          respect thereof) and Employment Agreement, no Seller shall
          make any claim against the Company or any of its
          subsidiaries for any other indebtedness or obligation.  The
          principal and accrued interest owed under the Loans as of
          the date hereof by the Company to each Seller are as set
          forth on Exhibit B.  Except for its rights pursuant to the
          terms of the Loans and Employment Agreements and any rights
          which each Seller has pursuant to the terms of the
          Securities, each Seller acknowledges that it owns no rights
          or interest in any of the assets of the Company or any of
          its subsidiaries.

                    7.2  Effective upon the Closing Time, each Seller,
          severally and not jointly, irrevocably, unconditionally and
          completely releases and forever discharges Company, Buyer and
          Ballard Medical, and their officers and directors, from any
          claim, controversy, demand, right, obligation, liability,
          and cause of action of every kind and nature (collectively,
          a "Claim") arising out of or relating to Seller's ownership 
          interest in Company; provided, however, that this release shall not
          relate to (i) any Claim of Seller arising out of or relating
          to a breach of this Agreement, (ii) any Claim of Seller
          under any Loans not paid in full in cash on the Closing
          Time, (iii) any Claim of Seller under any Employment
          Agreements, or (iv) if Seller is an officer or director of
          Company or any subsidiary of Company, any Claim to
          indemnification under (1) any agreement between Seller and
          Company or any such subsidiary, (2) Company's or such
          subsidiary's certificate of incorporation or bylaws, or (3)
          any insurance policy maintained by or on behalf of Company
          or any such subsidiary.

          covenants or undertakings with respect to the transactions

          be entitled to recover its costs and attorneys' fees.

                    8.6  HEADINGS.  The section headings herein are
          for convenience of reference only, do not constitute part of

          shall not be affected thereby.  To the extent permitted by

          renders any provision of this Agreement invalid, illegal or 
          unenforceable in any respect.

          original.

          representations, warranties, covenants and agreements of
          each of the parties to this Agreement shall survive the

          contemplated by this Agreement.

          affiliates to, issue or cause the publication of any press
          release or other announcement with respect to this Agreement
          or the transactions contemplated hereby without the consent
          of the other parties, which consent shall not be
          unreasonably withheld.  
 
                    Notwithstanding the foregoing, in the event any such press
          release or announcement is required by law or stock exchange
          regulation to be made by the party proposing to issue the
          same, consent shall not be required but such party shall use

          parties prior to the issuance of any such press release or
          announcement.

                            STOCK PURCHASE AGREEMENT

               This Stock Purchase Agreement (this "Agreement") is
          made and entered into as of the time on December 10, 1996
          which all parties hereto have executed and delivered this
          Agreement  ("Closing Time"), by and among SO-CAL PARTNERS,
          L.P., a Georgia limited partnership  ("Seller"), Ballard
          Acquisition Corporation, a Colorado corporation, all of
          whose capital stock is owned directly by Ballard Medical
          Products ("Buyer"), and Ballard Medical Products, a Utah
          corporation ("Ballard"), with respect to the following
          facts:

               A.   Seller owns 123,428 shares of the outstanding
          Common Stock of Cardiotronics Systems, Inc., a Colorado
          corporation (the "Company").

               B.   Seller desires to sell all of its shares of Common
          Stock of the Company (the "Shares") to Buyer, and Buyer is
          willing to purchase the Shares from Seller, all upon the
          terms and conditions contained herein.

               NOW, THEREFORE, in consideration of the foregoing
          premises and the mutual covenants contained herein, the
          parties hereto agree as follows:

               1.   PURCHASE AND SALE OF STOCK.  At the Closing Time,
          Seller hereby sells to Buyer, and Buyer hereby purchases
          from Seller, all of its Shares at an effective price of
          Three Dollars and Seventy-Five Cents ($3.75) per share
          ("Purchase Price").  The Purchase Price shall be paid to
          Seller by cashier's check in the amount of One Thousand
          Dollars ($1,000.00) and execution and delivery of a
          promissory note in favor of Seller in the amount of
          $461,855.00, with terms and conditions satisfactory to Buyer
          and Seller ("Promissory Note").  Concurrently herewith,
          Seller shall deliver to Buyer the certificate representing
          the Shares together with a duly executed irrevocable stock
          power with signature guaranteed.  Execution of this
          Agreement by Seller, Buyer and Ballard Medical hereby
          acknowledges receipt of the Promissory Note, certificate and
          irrevocable stock power. 

               2.   REPRESENTATIONS AND WARRANTIES OF SELLER.  Seller
          hereby represents and warrants to Company, Buyer and Ballard
          Medical that:

                    2.1  Seller has full power and authority to
          execute and deliver this Agreement and to perform its
          obligations hereunder.  This Agreement has been duly
          executed and delivered by Seller and constitutes the valid
          and binding obligation of Seller, enforceable against Seller
          in accordance with its terms.  

                    2.2  The execution and delivery of this Agreement 
          and the performance by Seller of its obligations hereunder
          will not conflict with, violate or constitute a default
          (with or without the giving of notice, lapse of time or
          both) under its partnership agreement or similar
          organizational documents or any note, mortgage, lease
          agreement, bond, indenture, instrument, license, franchise
          or permit, order, judgment, writ or decree, which conflict,
          violation or default will, in the case of this clause, have
          a material adverse effect on Company's business, the
          transactions contemplated by the Merger Agreement by and
          among Company, Buyer and Ballard Medical ("Merger
          Agreement") or Seller's ability to perform its obligations
          hereunder.

                    2.3  No consent or approval by, notice to or
          registration with, any governmental or administrative
          authority or board or third party is required on the part of
          Seller in connection with the execution and delivery by
          Seller of this Agreement or the performance by Seller of its
          obligations hereunder, except for consents, approvals,
          notices or registrations that will not individually, or in
          the aggregate, have a material adverse effect on Company's
          business, the transactions contemplated by the Merger
          Agreement or Seller's ability to perform its obligations
          hereunder.

                    2.4  As of the Closing Time, Seller's only
          ownership of, or interest in, Company  common stock or
          preferred stock or any other equity securities of Company
          consists solely of 123,428 Shares of Common Stock (the
          "Securities").  The undersigned has good title to the
          Securities, and such Securities are owned by the undersigned
          free and clear of any lien, claim, charge, encumbrance,
          security interest, title defect or other restriction (other
          than restrictions on transfer imposed by federal or state
          securities laws).

                    2.5  To the knowledge of Seller, the Securities
          acquired by Seller from Company were issued and sold to
          Seller in compliance with the registration requirements of
          the Securities Act of 1933, as amended ("Securities Act"), 
          and applicable state securities laws.  The Securities are
          not subject to any voting trust or voting agreement.

                    2.6  Seller has discussed the tax consequences of
          this Agreement with his or its counsel or tax advisor to the
          extent Seller deemed necessary. 

               3.   REPRESENTATIONS AND WARRANTIES OF BUYER AND
          BALLARD MEDICAL.  Buyer and Ballard Medical hereby represent
          and warrant to Seller as follows:

                    3.1  CORPORATE ORGANIZATION; DUE AUTHORIZATION AND  
          VALIDITY OF AGREEMENT.  Buyer is a corporation duly
          organized, validly existing and in good standing under the
          laws of Colorado, and Ballard Medical is a corporation duly
          organized, validly existing and in good standing under the
          laws of Utah.  Both Buyer and Ballard Medical have all
          requisite corporate power and authority to enter into this
          Agreement and the Merger Agreement and to carry out its
          obligations under this Agreement and the Merger Agreement. 
          The execution and delivery of this Agreement by Buyer and
          Ballard Medical and the performance of the obligations of
          Buyer and Ballard Medical hereunder have been duly
          authorized by all necessary corporate action by the
          respective Board of Directors of Buyer and Ballard Medical,
          and no other corporate proceedings on the part of Buyer or
          Ballard Medical are necessary to authorize such execution,
          delivery and performance.  This Agreement has been duly
          executed by Buyer and Ballard Medical and constitutes their
          legal, valid and binding obligation, enforceable against
          Buyer and Ballard Medical in accordance with its terms. 

                    3.2  NO CONFLICT OR VIOLATION.  The execution,
          delivery and performance by Buyer and Ballard Medical of
          this Agreement do not and will not violate or conflict with
          any provision of the charter documents or by-laws of Buyer
          or Ballard Medical and do not and will not violate any
          provision of law, or any order, judgment or decree of any
          court or other governmental or regulatory authority, nor
          violate nor will result in a breach of or constitute (with
          due notice or lapse of time or both) a default under any
          contract, lease, loan agreement, mortgage, security
          agreement, trust indenture or other agreement or instrument
          to which Buyer or Ballard Medical is a party or by which it
          is bound or to which any of its properties or assets is
          subject, which conflict, violation or default will, in the
          case of this clause, have a material adverse effect on
          Buyer's or Ballard Medical's business, the transactions
          contemplated by the Merger Agreement or Buyer's or Ballard
          Medical's ability to perform their respective obligations
          hereunder.

                    3.3  INVESTMENT INTENT.  The Shares will be
          acquired hereunder solely for the account of Buyer for
          investment purposes only and not with a view to or for sale
          in connection with any distribution of the securities of the
          Company and will not be sold or transferred by Buyer except
          in compliance with the Securities Act and applicable state
          law.

               4.   RESIGNATION OF  DIRECTORS.  As of the Closing
          Time, Richard B. Emmitt shall submit his resignation from
          the board of directors of Company.

                    8.4  ENTIRE AGREEMENT. This Agreement together
          with the other agreements referred to herein embodies the
          entire agreement and understanding of the parties with
          respect to the transactions contemplated hereby and
          supersedes all prior written or oral commitments,

          are no restrictions, agreements, promises, warranties,
          covenants or undertakings with respect to the transactions
          contemplated hereby other than those expressly set forth
          herein.

          shall not be affected thereby.  To the extent permitted by
          applicable law, each party waives any provision of law which

          or the transactions contemplated hereby without the consent
          of the other parties, which consent shall not be
          unreasonably withheld.  Notwithstanding the foregoing, in
          the event any such press release or announcement is required
          by law or stock exchange regulation to be made by the party
          proposing to issue the same, consent shall not be required
          but such party shall use its best efforts to consult in good
          faith with the other parties prior to the issuance of any

                                        CORPORATION

                                        By:  Dale H. Ballard,
                                             President  


                                MERGER AGREEMENT

               This   Merger Agreement   (hereinafter  called  this  
          "Agreement"),  dated as of the 10th day of  December,  1996
          ("Closing Date") by and among  Ballard Medical Products,  a
          Utah corporation  ("Ballard"),   Ballard Acquisition 
          Corporation, a Colorado corporation, all of whose capital
          stock is owned directly by  Ballard  ("Merger Sub"), and 
          Cardiotronics Systems, Incorporated, aka Cardiotronics
          Systems, Inc.,  a Colorado corporation  ("Cardiotronics"). 

                Stock  Purchase  Agreements   have  been executed by
          and among  Ballard,  Merger Sub, and certain stockholders of 
          Cardiotronics,  whereby Merger Sub has purchased  over 
          ninety percent (90%) of the outstanding shares of 
          Cardiotronics  ("Stock Purchase Agreement").

               The Boards of Directors of  Ballard,  Merger Sub and 
          Cardiotronics  deem it advisable for the mutual benefit of 
          Ballard,  Merger Sub and  Cardiotronics,  and their
          respective shareholders, that  Ballard  acquire 
          Cardiotronics  by the merger of  Merger Sub into
          Cardiotronics   under  the terms and conditions hereinafter
          set forth (the "Merger"), and have adopted resolutions
          authorizing the transactions contemplated by this Agreement.

                Ballard,  the sole shareholder of Merger Sub, deems it
          advisable and in its best interest for  Ballard  to acquire 
          Cardiotronics  by the Merger, and has adopted resolutions
          authorizing the transactions contemplated by this Agreement.

               In consideration of the premises and of the mutual
          agreements, representations, warranties and covenants
          contained herein, the parties hereto, intending to be
          legally bound, hereby agree as follows:

                                    ARTICLE I

                                   THE MERGER

               Section 1.1  ACTIONS TO BE TAKEN.  Subject to the terms
          and conditions of this Agreement, including the fulfillment
          (or waiver) of all conditions to the obligations of the
          parties contained herein, at the Effective Time (as
          hereinafter defined) and pursuant to Title 7 of the Colorado
          Revised Statutes (the "Colorado Statutes"), the following
          shall occur:

                    (a)   Merger Sub shall  be merged with and into 
          Cardiotronics,  which shall be the surviving corporation
          (the "Surviving Corporation").  The separate existence and
          corporate organization of  Merger Sub shall  cease at the
          Effective Time, and thereupon  Cardiotronics and   Merger
          Sub shall  be a single corporation, the name of which shall  
          be  "Cardiotronics." 

                    (b)  At the Effective Time, the effect of the
          Merger shall be as provided in the applicable provisions of
          the Colorado Statutes.  Without limiting the generality of
          the foregoing, at the Effective Time, all the property,
          right, privileges, powers and franchises of   Cardiotronics 
          and Merger Sub shall vest in the Surviving Corporation and
          all debts, liabilities, obligations, restrictions,
          disabilities and duties of  Cardiotronics  and Merger Sub
          shall become the debts, liabilities, obligations,
          restrictions, disabilities and duties of the Surviving
          Corporation. 

                    (c)  The Articles of Incorporation of 
          Cardiotronics shall  be and remain the articles of
          incorporation of the Surviving Corporation until amended as
          provided by law. 

                    (d)  The By-Laws of  Cardiotronics shall  be and
          remain the by-laws of the Surviving Corporation until
          amended, as provided by law or by the articles of
          incorporation or the by- laws of the Surviving Corporation.

                    (e)  The directors of Merger Sub immediately prior
          to the Effective Time shall be the initial directors for the
          Surviving Corporation, each to hold office in accordance
          with the Articles of Incorporation and By-laws of the
          Surviving Corporation, and the officers of  Cardiotronics
          immediately  prior to the Effective Time shall be the
          initial officers of the Surviving Corporation, in each case
          until their respective successors are duly elected or
          appointed and qualified.

          As soon as practicable after the execution of this
          Agreement, Articles of  Merger or such other documents as
          are necessary,  properly approved and executed in accordance
          with the Colorado Statutes (the "Articles of Merger"), shall
          be filed with the Secretary of State of the State of
          Colorado.  The Merger shall become effective when the
          Articles of Merger are so filed.  (The date and time when
          the Merger becomes effective is referred to in this
          Agreement as the "Effective  Time".)

               Section 1.2  COMMON STOCK OF SURVIVING CORPORATION.  At
          the Effective Time, each issued and outstanding share of
          common stock of Merger Sub shall be converted into one
          validly issued, fully paid and nonassessable share of common
          stock of the Surviving Corporation. 

               Section 1.3  CONVERSION OR CANCELLATION OF 
          CARDIOTRONICS  COMMON STOCK AND  CARDIOTRONICS  PREFERRED
          STOCK.  As of the Effective Time, by virtue of the Merger

          par value $0.012 per share  ("Cardiotronics  Common Stock"),

          per share (collectively, the  "Cardiotronics  Preferred
          Stock"),  (Cardiotronics  Common Stock and  Cardiotronics 
          Preferred Stock being sometimes collectively referred to
          herein as  "Cardiotronics  Capital Stock") then held in the
          treasury of  Cardiotronics  shall be canceled and retired.

                    (b)  Any shares of  Cardiotronics  Preferred Stock
          issued and outstanding immediately prior to the Effective
          Time (other than any shares of  Cardiotronics  Preferred
          Stock to be canceled pursuant to Section  1.3(a))  shall be
          converted into the number of shares of  Cardiotronics 
          Common Stock into which they are convertible according to
          their rights and preferences under the Articles of
          Incorporation of  Cardiotronics.   There are outstanding no
          shares of  Cardiotronics  Class B Preferred Stock, 2,764,622
          shares of Class C Convertible Preferred Stock, 2,119,828

          shares of  Cardiotronics  Common Stock for a total of
          2,891,155 shares of  Cardiotronics  Common Stock.

                    (c)  Any shares of  Cardiotronics  Common Stock
          issued and outstanding immediately prior to the Effective
          Time, 

                    INCLUDING shares of  Cardiotronics  Common Stock
          resulting from the conversion of  Cardiotronics  Preferred
          Stock pursuant to Section  1.3(b)  above;

                    BUT EXCLUDING any shares of  Cardiotronics  Common
          Stock to be canceled pursuant to Section  1.3(a)  above;

                    AND EXCLUDING any shares with respect to which the
          statutory right of dissent has been perfected, as provided
          in Section  1.4  below;

          shall be exchanged for Three Dollars and Seventy-Five Cents
          ($3.75) per share ("Purchase Price").

               Section 1.4  DISSENTING SHARES.  Each holder of shares
          of  Cardiotronics  Capital Stock  who has complied with all
          requirements for perfecting shareholders rights of dissent,
          as set forth in Article 113 of the Colorado Statutes, shall
          be entitled to such dissenters' rights under the Colorado
          Statutes with respect to such shares (the "Dissenting
          Shares").  

               Section 1.5   CARDIOTRONICS  OPTIONS.  At the Closing
          Date, each then outstanding option  ("Cardiotronics 
          Option") granted under the  Cardiotronics  1993 Stock Option
          Plan, 1994 Stock Option Plan and 1995 Stock Option Plan
          (collectively, the  "Cardiotronics  Stock Option Plans"),
          which has an exercise price, regardless whether such option
          has vested or is exercisable, of less than the Purchase
          Price shall be converted into the right to receive from
          Merger Sub an amount equal to the difference between the
          Purchase Price and the exercise price for such option;
          provided that such optionholder agrees to cancel in writing
          any remaining options.  All remaining outstanding 
          Cardiotronics  Options granted under the  Cardiotronics 
          Stock Option Plans will remain outstanding.

               Section 1.6  EXCHANGE OF CERTIFICATES. 

                    (a)  EXCHANGE AGENT.  As of the Effective Time, 
          Ballard  shall deposit, or shall cause to be deposited, with
          Corporate Stock Transfer or such other bank or trust company
          as may be designated by  Ballard  and is reasonably
          satisfactory to  Cardiotronics  (the "Exchange Agent"), for
          the benefit of the holders of shares of  Cardiotronics 
          Capital Stock, for exchange in accordance with this Article
          I through the Exchange Agent, cash sufficient to purchase
          all outstanding shares of  Cardiotronics  Capital Stock
          purchasable pursuant to Section  1.3. 

                    (b)  EXCHANGE PROCEDURES.  As promptly as
          practicable after the Effective Time,  Ballard  shall cause
          the Exchange Agent to mail to each holder of a certificate
          or certificates which immediately prior to the Effective
          Time represented outstanding shares of  Cardiotronics 
          Capital Stock (the "Certificates") (i) a letter of
          transmittal (which shall specify that delivery shall be
          effected, and risk of loss and title to the Certificates
          shall pass, only upon proper delivery of the Certificates to
          the Exchange Agent, and shall be in customary form) and (ii)
          instructions for use in effecting the surrender of the
          Certificates in exchange for cash.  Upon surrender to the
          Exchange Agent of a Certificate for cancellation, together
          with such letter of transmittal, duly executed, and such
          other documents as may be required pursuant to such
          instructions, the holder of such Certificate shall be
          entitled to receive in exchange therefor cash equal to that
          number of shares of  Cardiotronics  Common Stock formerly
          represented by such Certificate (after taking into account
          all shares of  Cardiotronics  Common Stock then held by such
          holder) multiplied by the Purchase Price.  In the event of 
          transfer of ownership of shares of  Cardiotronics  Capital
          Stock which transfer is not registered in the transfer
          records of  Cardiotronics,  cash equal to that number of
          shares of  Cardiotronics  Common Stock multiplied by the
          Purchase Price may be paid to a transferee if the  
          Certificate representing such shares of  Cardiotronics 
          Capital Stock is presented to the Exchange Agent,
          accompanied by all documents required to evidence and effect
          such transfer and by evidence that any applicable stock
          transfer taxes have been paid.  Until surrendered as
          contemplated by this Section  1.6,  each Certificate shall
          be deemed at any time after the Effective Time to represent
          only the right to receive cash upon such surrender.

                    (c)  LOST CERTIFICATES.  Notwithstanding the
          requirements of any provision of this Section  1.6  that
          Certificates be deposited with or surrendered to the
          Exchange Agent, in  the event Certificates have become
          destroyed, lost or stolen, in lieu of such deposit or
          surrender registered holders of such Certificates shall
          furnish to the Exchange Agent, evidence satisfactory to the
          Exchange Agent, in its discretion, of the ownership of and
          the destruction, loss or theft of such Certificates, and
          shall furnish to the Exchange Agent, an indemnity
          satisfactory to it and to  Ballard,  in their discretion,
          and shall comply with such other reasonable regulations as
          the Exchange Agent may prescribe.

               Section 1.7  ARTICLES OF MERGER; OTHER NECESSARY
          DOCUMENTS.   The  Board of Directors of  Cardiotronics 
          shall  take such actions as are necessary, as set forth in
          Colorado Business Corporation Act Section 7-111-104, to
          effectuate the Merger; including, but not limited to,
          causing the Articles of Merger to be filed with the
          Secretary of State of the State of Colorado and taking such
          other and further actions as may be required by the Colorado
          Statutes in connection with such filing and in order to
          consummate the Merger.

                                   ARTICLE II

            REPRESENTATIONS AND WARRANTIES OF BALLARD AND MERGER SUB

               Ballard and Merger Sub represent, warrant to, and agree
          with, Cardiotronics as follows:

               Section 2.1  CORPORATE ORGANIZATION.  Ballard is a
          corporation duly organized, validly existing and in good
          standing under the laws of the State of Utah, Merger Sub is
          a corporation duly organized, validly existing and in good
          standing under the laws of the State of Colorado and each
          has all requisite corporate power and authority to own,
          operate and lease its properties and to conduct its business
          as it is now being conducted.  Each of Ballard's significant
          subsidiaries (the term "significant subsidiary" being
          defined for purposes of this Agreement in Section 8.7) is a
          corporation duly organized, validly existing and in good
          standing under the laws of its respective jurisdiction of
          incorporation, and Ballard and each of its significant  
          subsidiaries is duly qualified or licensed as a foreign
          corporation in each other jurisdiction where it owns or
          leases substantial properties, except where the failure to
          be so qualified or licensed would not have a material
          adverse effect on the financial condition, properties or
          businesses of Ballard and its subsidiaries taken as a whole. 
          Ballard has previously delivered to Cardiotronics a true and
          complete copy of its Articles of Incorporation and By-Laws.

               Section 2.2 AUTHORIZATION, EXECUTION AND DELIVERY. 
          Ballard and Merger Sub each has the corporate power and
          authority to enter into this Agreement and to carry out its
          obligations hereunder.  The execution and delivery of this
          Agreement and the other agreements and documents referred to
          herein to which Ballard or Merger Sub is or will be a party
          or a signatory (the "Ballard Ancillary Agreements") by
          Ballard and Merger Sub and the consummation of the
          transactions contemplated hereby have been duly authorized
          by the respective Board of Directors of Ballard and Merger
          Sub and no other corporate proceedings on the part of
          Ballard are necessary to authorize the execution and
          delivery Agreement and the transactions contemplated hereby
          or thereby.  This Agreement has been duly and validly
          executed and delivered by Ballard and Merger Sub and
          constitutes, and upon execution and delivery thereof as
          contemplated by this Agreement, the Ballard Ancillary
          Agreements will constitute, the legal, valid and binding
          agreements of Ballard and Merger Sub, enforceable against
          Ballard and Merger Sub in accordance with its and their
          respective terms, except to the extent that enforceability
          thereof may be limited by applicable bankruptcy, insolvency,
          reorganization or other similar laws affecting the
          enforcement of creditors' rights generally and by principles
          of equity regarding the availability of remedies
          ("Enforceability Exceptions").  Neither Ballard nor Merger
          Sub is subject to or obligated under any charter, by-law or
          contract provision or any note, mortgage, lease, agreement,
          bond, indenture, instrument, license, franchise or permit,
          or subject to any order, judgment, injunction, writ or
          decree, which would be breached or violated by its executing
          or carrying out of this Agreement, except for breaches or
          violations, if any, which individually or in the aggregate
          would not have a material adverse effect on the financial
          condition, properties or businesses of Ballard and its
          subsidiaries taken as a whole.  Other than in connection
          with or in compliance with the provisions and requirements
          of  the Colorado Statutes, the Securities Act of 1933, as
          amended (the "Securities Act"), the Securities Exchange Act
          of 1934, as amended (the "Exchange Act"), the NYSE and the
          securities or blue sky laws of the various states, no
          authorization, consent or approval of, or filing with, any
          public body or governmental authority is necessary for the
          consummation by Ballard or Merger Sub of the transactions
          contemplated by this Agreement, except for such  
          authorizations, consents, approvals or filings, the failure
          to obtain or make which would not have a material adverse
          effect on the financial condition, properties or businesses
          of Ballard and its subsidiaries taken as a whole.

               Section 2.3  REPORTS; ACCURACY OF INFORMATION.  Ballard
          has previously furnished to Cardiotronics true and complete
          copies of its Annual Reports on Form 10-K (including all
          amendments thereto) filed with the SEC for each of its
          fiscal years ended September 30, 1993 through September 30,
          1996, inclusive, and a true and complete copy of its
          Quarterly Reports (including all amendments thereto) on Form
          10-Q filed with the SEC for each of the fiscal quarters
          ended December 31, 1995, March 31, 1996 and June 30, 1996
          (the "Ballard Reports").  Each of the balance sheets
          included in the Ballard Reports, as finally amended
          (including any related notes and schedules), fairly presents
          the consolidated financial position of Ballard as of its
          date and the other financial statements included in the
          Ballard Reports, as finally amended (including any related
          notes and schedules), fairly present the consolidated
          results of operations or other information included therein
          of Ballard for the periods or as of the dates therein set
          forth, subject, where appropriate, to normal year-end
          adjustments, in each case in accordance with generally
          accepted accounting principles consistently applied during
          the periods involved (except as otherwise stated therein). 
          Ballard also has previously furnished to Cardiotronics a
          true and complete copy of (i) each final prospectus and
          definitive proxy statement filed by Ballard with the SEC
          since September 30, 1996 and (ii) each report other than the
          Ballard Reports filed by Ballard with the SEC since
          September 30, 1996.  None of the documents referred to in
          this Section 2.3 contained, as of its date, any untrue
          statement of a material fact or any omission to state a
          material fact required to be stated therein or necessary in
          order to make the statements therein, in light of the
          circumstances under which they were made, not misleading.

               Section 2.4  ABSENCE OF CHANGES.  Except as described
          in any document referred to in Section 2.3, since September
          30, 1996, there has not been any material adverse change in
          the financial condition, properties or businesses of Ballard
          and its subsidiaries taken as a whole.

               Section 2.5  COMPLIANCE WITH LAWS.  The businesses of
          Ballard and its subsidiaries are not being conducted in
          violation of any applicable law, ordinance, regulation,
          decree or order of any governmental entity ( Laws ), except
          for violations which either singly or in the aggregate do
          not and are not expected to have a material adverse effect
          on the financial condition, properties or businesses of
          Ballard and its subsidiaries taken as a whole.

          referred to in any of the documents referred to in Section

          federal, state, municipal or other governmental department,
          commission, board, bureau, agency or instrumentality, which
          either singly or in the aggregate is likely to result in any
          material adverse change in the financial condition,
          properties or businesses of Ballard and its subsidiaries
          taken as a whole.

               Except as set forth in the Disclosure Memorandum to the
          Merger Agreement, dated as of the Closing Date
          ("Cardiotronics Disclosure Memorandum"), Cardiotronics
          represents, warrants to, and agrees with, Ballard and Merger
          Sub as follows:

               Section 3.1  CORPORATE ORGANIZATION.  Cardiotronics is
          a corporation duly organized, validly existing and in good
          standing under the laws of the State of Colorado and is duly
          qualified or licensed as a foreign corporation in each other
          jurisdiction where it owns or leases substantial properties,
          except where the failure to be so qualified or licensed
          would not have a material adverse effect on the financial
          condition, properties or businesses of Cardiotronics and its
          subsidiaries taken as a whole ("Cardiotronics' Business"). 
          Cardiotronics has one subsidiary, R2 Medical Systems, Inc. (R2"),
          which is a corporation duly organized, validly
          existing and in good standing under the laws of its
          jurisdiction of incorporation and is duly qualified or
          licensed as a foreign corporation in each other jurisdiction
          where it owns or leases substantial properties, except where
          the failure to be so qualified or licensed would not have a
          material adverse effect on the financial condition,
          properties or businesses of Cardiotronics and its subsidiary
          taken as a whole.  Cardiotronics has no subsidiaries other
          than R2.  Cardiotronics has no interest, direct or indirect,
          and has no commitment to purchase any interest, direct or
          indirect, in any other corporation (except R2) or in any
          partnership, joint venture or other business enterprise or
          entity.  Cardiotronics and its subsidiary have the requisite
          corporate power and authority to carry on their respective
          business as it is now being conducted.  Cardiotronics has
          previously delivered to Ballard a true and complete copy of  
          its Certificate of Incorporation and By-Laws.

               Section 3.2  CAPITALIZATION.  The authorized capital
          stock of Cardiotronics consists of 100,000,000 shares of

          issuable pursuant to the foregoing being included in the
          aggregate number of shares reserved for issuance as of
          November 27, 1996, as set forth above), Cardiotronics does
          not have any outstanding subscriptions, options, warrants,
          rights or other agreements or commitments obligating

          is no authorized or outstanding security of any kind
          convertible into or exchangeable for any Cardiotronics

          Cardiotronics' subsidiary, R2, have been validly issued, are
          fully paid and nonassessable and are owned free and clear of  
          all liens, charges, claims and encumbrances.

               Section 3.3  AUTHORIZATION, EXECUTION AND DELIVERY. 
          Cardiotronics has the corporate power and authority to enter
          into this Agreement and to carry out its obligations
          hereunder.  The execution and delivery of this Agreement and
          the other agreements and documents referred to herein to
          which Cardiotronics is or will be a party or a signatory
          (the "Cardiotronics Ancillary Agreements") and the
          consummation of the transactions contemplated hereby have
          been duly authorized by its Board of Directors and, no other
          corporate proceedings on the part of Cardiotronics are
          necessary to authorize this Agreement and the transactions
          contemplated hereby or thereby.  This Agreement has been
          duly and validly executed and delivered by Cardiotronics and
          constitutes, and upon execution and delivery thereof as
          contemplated by this Agreement, the Cardiotronics Ancillary
          Agreements will constitute, the legal, valid and binding
          agreements of Cardiotronics, enforceable against
          Cardiotronics in accordance with its and their respective
          terms, subject to the Enforceability Exceptions. 
          Cardiotronics is not subject to or obligated under any
          charter, by- law or contract provision or any note,
          mortgage, lease, agreement, bond, indenture, instrument,
          license, franchise or permit, or subject to any order,
          judgment, injunction, writ or decree, which would be
          breached or violated by its executing or carrying out this
          Agreement except for breaches or violations, if any, which
          individually and in the aggregate would not have a material
          adverse effect on Cardiotronics' Business.  Other than in
          connection with or in compliance with the provisions and
          requirements of the Colorado Statutes, the Securities Act,
          the Exchange Act, the Nasdaq SmallCap Market and the
          securities or blue sky laws of the various states, no
          authorization, consent or approval of, or filing with, any
          public body or governmental authority is necessary for the
          consummation by Cardiotronics of the transactions
          contemplated by this Agreement, except for such
          authorizations, consents, approvals or filings, the failure
          to obtain or make which would not have a material adverse
          effect on Cardiotronics' Business.

               Section 3.4  REPORT, ACCURACY OF INFORMATION. 
          Cardiotronics has previously furnished to Ballard true and
          complete copies of its Annual Reports on Form 10-K
          (including all amendments thereto) filed with the SEC for
          each of its fiscal years ended December 31, 1993 through
          December 31, 1995, inclusive, and a true and complete copy
          of its Quarterly Reports (including all amendments thereto)
          on Form 10-Q filed with the SEC for each of the fiscal
          quarters ended March 31, 1996, June 30, 1996, and September
          30, 1996 (the "Cardiotronics Reports").  Each of the balance
          sheets included in the Cardiotronics Reports, as finally
          amended (including any related notes and schedules), fairly  
          presents the consolidated financial position of
          Cardiotronics as of its date and the other financial
          statements included in the Cardiotronics Reports, as finally
          amended (including any related notes and schedules), fairly
          present the consolidated results of operations or other
          information included therein of Cardiotronics for the
          periods or as of the dates therein set forth, subject, where
          appropriate, to normal year-end adjustments, in each case in
          accordance with generally accepted accounting principles
          consistently applied during the periods involved (except as
          otherwise stated therein).  Cardiotronics has also
          previously furnished to Ballard a true and complete copy of
          (i) each final prospectus and definitive proxy statement
          filed by Cardiotronics or any of its significant
          subsidiaries with the SEC since December 31, 1995, and (ii)
          each report other than the Cardiotronics Reports filed by
          Cardiotronics with the SEC since December 31, 1995.  None of
          the documents referred to in this Section 3.4 contained, as
          of its date, any untrue statement of a material fact or any
          omission to state a material fact required to be stated
          therein or necessary in order to make the statements
          therein, in light of the circumstances under which they were
          made, not misleading.

          reflected or reserved against in accordance with generally
          accepted accounting principles in the September 30, 1996
          Balance Sheet included in Cardiotronics' Form 10-Q for the

          December 31, 1995.

                    (c)  All of Cardiotronics' liabilities and
          obligations of any nature whatsoever (whether absolute,
          accrued, contingent, or otherwise and whether due or to
          become due), arising after September 30, 1996 and in excess

               Section 3.8  TITLE TO ASSETS AND PROPERTIES; CONDITION. 

                    (a)  Cardiotronics owns or leases or otherwise has
          the right to use all of its assets and properties, which are
          presently being used in or are reasonably necessary to carry
          on its business and operations as presently conducted, and
          such assets, properties and agreements are all of the
          assets, properties and agreements which are used in or are
          reasonably necessary to carry on its business and operations
          as presently conducted.  All assets and properties leased or
          owned are located in Cardiotronics' offices in Carlsbad,
          California. 

                    (b)  Each lease or agreement under which
          Cardiotronics is a lessee of any property, real or personal,
          owned by a third party is a valid and continuing agreement
          without any default of Cardiotronics thereunder or, to the
          best knowledge of Cardiotronics, of the other party thereto,
          and this Agreement and the consummation of the transactions
          contemplated hereby will not cause any default under any
          such lease or agreement.

                    (c)  Cardiotronics has good and marketable title
          to all property and assets which it owns, free and clear of
          all mortgages, liens, pledges, charges, claims, encumbrances
          or restrictions of any kind whatsoever (whether accrued,
          absolute, contingent, or otherwise), except liens for
          current property taxes not yet due and payable and liens
          that do not materially interfere with the ability of
          Cardiotronics to conduct its business or qualify as 
          material  liens.

                    (d)  Cardiotronics has not received any notice of
          violation of any regulation, ordinance, law, order or other
          requirement relating to the property, real or personal, or
          Cardiotronics' Business.  Cardiotronics is unaware of any
          changes in any such regulation, ordinance, law, order or
          other requirement affecting any such property or any
          condemnation proceeding, pending or threatened, which might  
          prohibit Cardiotronics from continuing its present use of
          such property or from using such property for the purpose
          for which it was acquired, or which might curtail or
          interfere with the present or proposed use of such property.

                    (e)  The furniture, fixtures, leaseholds,
          equipment and other personal property of Cardiotronics are
          in good operating condition and repair.

          Disclosure Memorandum contains an accurate and complete list

          All receivables of Cardiotronics (including accounts
          receivable, loans receivable, and advances) have arisen from
          and represent arms- length, bona fide transactions made in
          the ordinary course of business.  The receivables of
          Cardiotronics are good and collectible (net of applicable
          reserve for bad debts). 

               Section 3.10  TAXES.  Cardiotronics has filed all
          federal Tax returns and all state and foreign tax returns
          required to be filed, and has paid, or has made adequate
          provision or set up an adequate accrual or reserve for the
          payment of, all Taxes required to be paid in respect of all
          periods for which returns have been made or are due, and has
          established an adequate accrual or reserve for the payment
          of all Taxes payable in respect of the period subsequent to
          the last of said periods required to be so accrued or
          reserved (except in either case in an amount not material),
          and in its opinion it has no material liability for Taxes in
          excess of the amount so paid or accruals or reserves so
          established.  Cardiotronics is not delinquent in the payment
          of any material Tax and is not delinquent in the filing of
          any Tax returns, and no material deficiencies for any Tax
          have been threatened, claimed, proposed or assessed.  The
          Cardiotronics U.S., state and foreign income tax returns,
          respectively, have never been audited by the Internal
          Revenue Service or comparable state or foreign agencies. 
          For the purposes of this Agreement (except for purposes of
          the preceding sentence), the term "Tax" shall include all
          federal, state, local, foreign, income, gains, franchise,
          excise, property, sales, use, license, payroll, occupation,

          charges, fees, levies or assessments (whether payable
          directly or by withholding), and includes, with respect to
          such taxes, any estimated tax, interest and penalties or
          additions to tax and interest on such penalties and
          additions to tax.

          of Hazardous Substances, and there are no Hazardous
          Substances in the buildings or soil on, or in the ground
          water under, any properties which are owned or leased by
          Cardiotronics which could result in an obligation of
          Cardiotronics to remedy the condition.  There is no other
          liability of Cardiotronics under any Federal, state or local
          law or regulation relating to the environment.

          and Change in Control Agreements which relate to a Change in
          Control, including, but not limited to, the accelerated

                                MUTUAL COVENANTS

               Section 6.1  CONFIDENTIALITY.  Ballard, Merger Sub and
          Cardiotronics will use their best efforts to keep
          confidential any and all information furnished to one of
          them by the other or such other's subsidiaries or
          independent public accountants in connection with the
          transactions contemplated by this Agreement, and the
          business and financial review and investigation referred to
          in Section 4.2, except to the extent any such information
          may be generally available to the public, and Ballard,
          Merger Sub and Cardiotronics have instructed their
          respective officers, employees and other representatives
          having access to such information to comply with the
          obligation of confidentiality. 

               Section 6.2  EXPENSES.  Whether or not the Merger is

          Agreement.

               Section 6.3  PUBLIC ANNOUNCEMENTS.  Cardiotronics and
          Ballard agree that, recognizing that each has independent
          obligations with respect to the dissemination of material

                            MISCELLANEOUS PROVISIONS

               Section 8.1  AMENDMENT AND MODIFICATION.  This
          Agreement may not be amended, modified and supplemented with
          respect to any of the terms contained herein; provided,
          however, that this Agreement may be amended, pursuant to an
          amendment approved in writing by all of the parties to this
          Agreement and Robert S. Grimes or any subsequent independent
          director of Cardiotronics, with respect to any of the terms
          contained herein.

               Section 8.2  ASSIGNMENT; BINDING UPON SUCCESSORS AND
          ASSIGNS.  Neither party hereto may assign any of its rights
          or obligations hereunder without the prior written consent
          of the other party hereto.  This Agreement will be binding
          upon and inure to the benefit of the parties hereto and
          their respective successors and permitted assigns.

               Section 8.3  SURVIVAL OF PROVISIONS.  The respective
          representations, warranties, covenants and agreements of
          each of the parties to this Agreement shall survive the
          Closing Date and the consummation of the transactions
          contemplated by this Agreement.

               Section 8.4  INDEMNIFICATION.  After the Effective
          Time, Ballard and Merger Sub shall indemnify and hold
          harmless any person who was a director or officer of
          Cardiotronics at any time prior to the Effective Time and
          the heirs, executors and administrators of any such person,
          to the extent authorized or permitted by Cardiotronics'
          certificate of incorporation or by-laws or provided pursuant
          to the Colorado Revised Statutes in effect immediately prior
          to the Effective Time, against any liabilities, costs or
          expenses (including attorneys' fees) imposed upon or
          reasonably incurred by him or her in his or her capacity as,
          or arising out of his or her status as, or because of his or
          her having been a director or officer of Cardiotronics or
          any of its subsidiaries at any time prior to the Effective
          Time, provided that in each such case, such director or
          officer reasonably believed that he or she acted in the
          interest of Cardiotronics and did not violate his or her
          fiduciary duty to Cardiotronics.  Such obligations shall
          apply to any action, suit or proceeding commenced or
          threatened before or after the Effective Time.  To the
          extent available, Ballard agrees to cause the Surviving
          Corporation to maintain in effect for not less than three
          years after the Closing Date policies of directors' and
          officers' liability insurance comparable to those maintained
          by Cardiotronics with carriers comparable to Cardiotronics'
          existing carriers and containing terms and conditions which
          are no less advantageous in any material respect to the
          officers, directors and employees of Cardiotronics;
          provided, however, that the Surviving Corporation shall not
          be required to pay an annual premium for such insurance in  
          excess of two times the last annual premium paid prior to
          the date hereof, but in such case shall purchase as much
          coverage as possible for such amount.  Notwithstanding the
          above, neither Ballard nor Merger Sub will have any
          indemnity liability under this Section 8.4 with respect to
          any claim, lawsuit or proceeding brought or commenced by or
          on behalf of any "affiliates" of Cardiotronics within the
          meaning of Rule 145 promulgated by the SEC under the
          Securities Act, including, but not limited to, all officers
          and directors of Cardiotronics.

               Section 8.5  COUNTERPARTS; FACSIMILE SIGNATURE.  This
          Agreement may be executed in one or more counterparts, any
          of which counterparts may be executed by facsimile
          signatures, all of which shall be considered one and the
          same agreement, and shall become effective when one or more

          subsidiaries" shall refer to subsidiaries (as defined above)
          which constitute "significant subsidiaries" under Rule 405
