          ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

                    As of March 27, 1998, American Electromedics Corp.
          ("Registrant") and ESI Acquisition Corporation ("ESI"), a
          California corporation and wholly-owned subsidiary of the
          Registrant, entered into an Agreement and Plan of Merger with
          Equidyne Systems, Inc. ("Equidyne"), a California corporation
          with offices located in San Diego, California,  whereby, ESI will
          merge with and into Equidyne and Equidyne will become a wholly-
          owned subsidiary of the Registrant (the "Merger"). Upon the
          Merger, Equidyne shareholders will receive an aggregate of
          600,000 shares of Common Stock of the Registrant, subject to
          adjustment. Equidyne is a development company which holds patents
          and has obtained FDA market clearance for a needle-free drug
          injection product which the Registrant intends to incorporate
          into its line of medical products. It is anticipated that the
          Merger will take place during the first week of May 1998, subject
          to obtaining necessary approvals and customary closing
          conditions.

          SYSTEMS, INC., a California corporation ("ESI").


                                W I T N E S S E T H :
                                - - - - - - - - - -  


                     WHEREAS, Acquisition Corp. is a newly-formed wholly-
          owned subsidiary of AEC;

                     WHEREAS, AEC desires to acquire all of the issued and
          outstanding shares of ESI Common Stock, no par value (the "ESI
          Common Stock"), through the merger of Acquisition Corp. with and
          into ESI, pursuant to the terms hereinafter set forth (the
          "Merger");

                     WHEREAS, the respective Boards of Directors of AEC and
          Acquisition Corp. deem it advisable and in the best interests of
          AEC and Acquisition Corp. that Acquisition Corp. be merged with
          and into ESI upon the terms and conditions hereinafter specified;

                     WHEREAS, the Board of Directors of ESI deems it
          advisable and in the best interests of ESI that Acquisition Corp.
          be merged with and into ESI upon the terms and conditions
          hereinafter specified;

                     NOW, THEREFORE, in consideration of the mutual
          covenants and agreements hereinafter contained, the parties
          hereto, intending to be legally bound hereby, agree as follows:


                                      ARTICLE I

                       ADOPTION OF AGREEMENT AND PLAN OF MERGER

                     1.1 The Merger.  At the Effective Time (as defined in
                         ----------
          Section 1.2 hereof), in accordance with this Agreement and the 
          -----------
          relevant provisions of the California General Corporation Law
          (the "CGCL"), Acquisition Corp. shall be merged with and into
          ESI.  ESI shall be the surviving corporation of the Merger and
          ESI shall continue, and be deemed to continue, for all purposes
          after the Merger, and the existence of Acquisition Corp. shall
          cease at the Effective Time.

                     1.2 Effective Date of the Merger.  This Agreement 
                         --------------
          shall be submitted to the stockholders of ESI as provided in
          Section 5.4 hereof, and to the sole stockholder of Acquisition 
          -----------
          Corp., as provided in Section 5.4 hereof, for approval as soon as
                                -----------
          practicable after the execution of this Agreement.  Subject to
          the terms and conditions hereof and the authorization, approval
          and adoption hereof by the affirmative vote of AEC, in its
          capacity as the sole stockholder of Acquisition Corp., and of the
          holders of ESI Common Stock entitled to vote thereon holding at
          least a majority of the issued and outstanding shares of ESI
          Common Stock as provided by the CGCL.  A copy of the Agreement
          together with officer's certificates of AEC, Acquisition Corp.
          and ESI meeting the requirements of Section 1103 of the CGCL
          shall be delivered to the Secretary of State of California for
          filing (the time of such filing being the "Effective Time" and
          the date of such filing being the "Effective Date").

                     1.3 Surviving Corporation; Articles of Incorporation 
                         ------------------------------------------------
          of Surviving Corporation.  Following the Merger, ESI shall 
          ------------------------
          continue to exist under, and be governed by, the laws of the
          State of California, and AEC will own all of the issued and
          outstanding ESI Common Stock.  The Articles of Incorporation and
          By-Laws of ESI, as in effect as of the Effective Time, shall
          continue in full force and effect as the Articles of
          Incorporation and By-Laws of ESI.

                     1.4 Firm Shares; Conversion of ESI Common Stock; 
                         --------------------------------------------
          Cancellation of Acquisition Corp. Common Stock.  (a)  At the 
          ----------------------------------------------
          Effective Time, by virtue of the Merger and without any action on
          the part of Acquisition Corp., ESI or the holders of ESI Common
          Stock, the holders of ESI Common Stock (an "ESI Holder")
          immediately prior to the Effective Time shall receive 600,000
          shares of common stock, $.10 par value per share, of AEC ("AEC
          Common Stock"), which shall be the "Firm Shares" subject to
          adjustment as provided in this Section 1.4 and subject to the 
                                         -----------
          Escrow Agreement, as described in Section 6.7 hereof.  Each ESI 
                                            -----------
          Holder as of the Effective Date shall be entitled to receive a
          number of shares of AEC Common Stock equal to the product of
          (x) a fraction, the numerator of which being the number of shares
          of ESI Common Stock owned of record by the ESI Holder on the
          Effective Date and the denominator of which shall be the total
          issued and outstanding shares of ESI Common Stock on the
          Effective Date, multiplied by (y) the number of Firm Shares, or
          an additional Firm Shares pursuant to Subsection (c) or (d)
          below.  Until surrendered in accordance with the provisions of
          Section 1.5 hereof, each certificate of ESI Common Stock shall 
          -----------
          represent, for all purposes, only the right to receive the Firm
          Shares or appraisal rights under Section 1.9 hereof.
                                           -----------

                     (b) No adjustment shall be made to the number of Firm
          Shares if at any time during the ninety (90) day period
          immediately preceding and the six (6) month period immediately
          after the Effective Time (the "Measuring Period"), the closing
          price of AEC Common Stock on the OTC Electronic Bulletin Board or
          such other quotation system on which the AEC Common Stock is then
          traded (the "Closing Price") is equal to or greater than Three
          Dollars ($3.00) per share on any seven (7) trading days in any
          thirty (30) day period during the Measuring Period,
          notwithstanding the absence of trading or trading activity in AEC
          Common Stock on any number of days during any month in the
          Measuring Period.

                     (c) An adjustment of an additional 1,600,000 shares of
          AEC Common Stock shall be made to the number of Firm Shares if
          the Closing Price of AEC Common Stock fails to exceed One Dollar
          ($1.00) per share at any time during the Measuring Period.

                     (d) Should the average high Closing Price of AEC
          Common Stock (the "Average High Price") equal or exceed One
          Dollar ($1.00) per share for any five (5) consecutive trading
          days during the Measuring Period, but never attained the price as
          set forth in Subsection (b) above, then, an adjustment shall be
          made to the number of Firm Shares by adding a number of shares of
          AEC Common Stock equal to resultant of (x) a fraction, the
          numerator of which being (A) 3 minus (B) the Average High Price
          and the denominator of which being 2, multiplied by (Y)
          1,200,000, up to a maximum adjustment of 1,200,000 shares.  

                     (e) If between the date of this Agreement and the
          Effective Time the outstanding shares of AEC Common Stock shall
          have been changed into a different number of shares or a
          different class by reason of a stock dividend, subdivision,
          reclassification, recapitalization, split-up or combination, the
          number of Firm Shares shall be appropriately adjusted.

                     (f) At the Effective Time, (i) all shares of ESI
          Common Stock which are owned by ESI as treasury stock shall be
          canceled and retired and cease to exist, and (ii) all outstanding
          shares of ESI Preferred Stock shall be converted into ESI Common
          Stock pursuant to their respective terms.

                     (g) At the Effective Time, each share of Acquisition
          Corp. Common Stock issued and outstanding immediately prior to
          the Effective Time shall, by virtue of the Merger and without any
          action on the part of AEC, be canceled and cease to exist.

                     1.5 Exchange of Certificates.  (a) Prior to the 
                         ------------------------
          Effective Time, AEC shall select an exchange agent (the "Exchange
          Agent") reasonably acceptable to ESI to effectuate the delivery
          of the Firm Shares provided for in Section 1.4 hereof to holders
                                             -----------
          of ESI Common Stock upon surrender of certificates which
          immediately prior to the Effective Time represented outstanding
          shares of ESI Common Stock ("Certificates").

                     (b) As of the Effective Time, AEC shall provide, or
          shall take all steps necessary to provide, to the Exchange Agent,
          the maximum aggregate number of shares of AEC Common Stock
          representing the Firm Shares.  The Exchange Agent shall, pursuant
          to irrevocable instructions, make the deliveries of the Firm
          Shares required in respect of the Merger.

                     (c) Promptly after the Effective Time, the Exchange
          Agent shall mail to each record ESI Holder of an outstanding
          Certificate, determined as of the Effective Date, a form letter
          of transmittal (which shall specify that delivery shall be
          effected, and risk of loss and title to Certificates shall pass,
          only upon proper delivery of the Certificates to the Exchange
          Agent), advising such ESI Holder of the terms of the exchange
          effected by the Merger and the procedure for surrendering to the
          Exchange Agent such Certificate in exchange such Holder's share
          of the Firm Shares.

                     (d) Upon surrender of a Certificate to the Exchange
          Agent, together with such letter of transmittal, duly executed,
          the ESI Holder of such Certificate shall be entitled to receive
          in exchange therefor such Holder's unadjusted portion of Firm
          Shares, less ten (10%) percent of such ESI Holders' shares of AEC
          Common Stock that shall be delivered to the Escrow Agent to be
          held under the Escrow Agreement pursuant to Section 6.7 hereof, 
                                                      -----------
          and held for no more than five (5) months thereunder, subject to
          the terms and conditions of such Escrow Agreement, and the
          Certificate so surrendered shall forthwith be canceled.  Shares
          of AEC Common Stock shall be delivered to each ESI Holder as
          promptly as practicable and (except as hereinafter provided) in
          no event later than twenty (20) days after proper delivery of the
          applicable Certificates and letters of transmittal to the
          Exchange Agent. In the event of any adjustment in the Firm Shares
          by reason of Section 1.4(c) and (d) hereof, the additional Firm
          Shares shall be delivered to the ESI Holders following the
          procedures in this Section.

                     (e) All shares of AEC Common Stock issued upon
          exchange of the shares of ESI Common Stock in accordance with the
          terms hereof shall be deemed to have been issued in full
          satisfaction of all rights pertaining to such shares of ESI
          Common Stock.

                     (f) Neither Acquisition Corp., AEC nor ESI shall be
          liable to any ESI Holder for any such shares of AEC Common Stock
          delivered to a public official pursuant to any abandoned
          property, escheat or similar law.  Until surrendered in
          accordance with the provisions of this Section 1.5, each 
                                                 -----------
          Certificate shall represent, for all purposes, only the right to
          receive the Firm Shares or appraisal rights under Section 1.9 
                                                            -----------
          hereof.

                     (g) Any shares of AEC Common Stock which remain
          undistributed to ESI Holders for six (6) months after the
          Effective Time shall, except as provided by Section 1.5(d), be 
                                                      --------------
          delivered to AEC, upon demand, and any ESI Holder who has not
          theretofore complied with this Section 1.5 shall thereafter look
                                         -----------
          to AEC for the number of Firm Shares to which he is entitled.

                     1.6 No Fractional Shares.  No certificates or scrip 
                         --------------------
          for fractional shares of AEC Common Stock will be issued.  In
          lieu of issuing any such fractional shares to which and ESI
          Holder would otherwise be entitled to receive, the Exchange Agent
          shall round up or down to the nearest whole share of AEC Common
          Stock.

                     1.7 Certificates in Other Names.  If any certificate 
                         ---------------------------
          evidencing shares of AEC Common Stock is to be issued in a name
          other than that in which the Certificate surrendered in exchange
          therefore is registered, it shall be a condition of the issuance
          thereof that the Certificate so surrendered shall be properly
          endorsed and otherwise in proper form for transfer and that the
          person requesting such exchange pay to the Exchange Agent or to
          AEC acting solely in its corporate capacity, as the case may be,
          any transfer or other taxes required by reason of the issuance of
          a certificate for shares of AEC Common Stock in any name other
          than that of the registered holder of the Certificate surrendered
          or otherwise required or establish to the satisfaction of the
          Exchange Agent or of AEC acting solely in its corporate capacity,
          as the case may be, that such tax has been paid or is not
          payable.

                     1.8 Treatment of Options. At the Effective Time, all 
                         --------------------
          outstanding warrants, options or other rights to purchase ESI
          Common Stock ("ESI Warrants") as set forth on Schedule 3.4, shall
                                                        ------------
          be canceled.

                     1.9 Appraisal Rights. (a) Notwithstanding Sections 1.4
                         ----------------                      ------------
          and 1.5 hereof, shares of ESI Common Stock which are held by an 
          -------
          ESI Holder who has properly preserved and perfected appraisal
          rights with respect to such shares pursuant to the applicable
          provisions of the CGCL ("Dissenting Stockholder") shall not be
          converted into Firm Shares pursuant to Section 1.4 hereof, and 
                                                 -----------
          instead shall be treated in accordance with those provisions of
          the CGCL, as the case may be, unless and until the right of such
          Dissenting Stockholder under the applicable provisions of the
          CGCL to payment for his shares of ESI Common Stock shall cease.

                     (b) If any Dissenting Stockholder shall effectively
          withdraw or lose (through failure to perfect or otherwise) such
          Dissenting Stockholder's right to payment for any of such
          Dissenting Stockholder's shares of ESI Common Stock, such shares
          shall be automatically converted into the right to receive Firm
          Shares in accordance with Section 1.4 hereof.
                                    -----------

          Laws affecting creditors' rights and remedies generally and
          subject as to enforceability to general principles of equity,
          including principles of commercial reasonableness, good faith and
          fair dealing) and is in full force and effect.  Except as set
          forth on Schedule 3.10 (i) neither ESI nor, to ESI's knowledge,

          any such agreement, (ii) no event, occurrence or condition exists
          (including the transactions contemplated under this Agreement)
          which, with the lapse of time or the giving of notice or both,

                                          -------------
          Agreement or the Merger.

                     (c)  Schedule 3.10 sets forth a correct and complete 
                          -------------
          list of the ten largest customers of ESI in terms of net revenues
          during each of the 1997 and 1996 fiscal years and the first two
          months of fiscal 1998, showing the approximately total net
          revenue received in each such period from each such customer. 
          Except to the extent set forth on Schedule 3.10, since December 
                                            -------------
          31, 1997, there has not been any adverse change in the business
          relationship between ESI and any customer listed on such
          Schedule.

                     3.11  Property.  Schedule 3.12 is a complete and 
                           --------   -------------
          correct list of all personal property of ESI (other than
          inventory) not reflected on any other Schedule hereto and having
          a book value exceeding $5,000.  Except as set forth on Schedule 
                                                                 --------
          3.12, ESI now has and on the Closing Date will have good and 
          ----
          marketable title to all personal property purported to be owned
          by it, free and clear of all Liens.  The material, tangible
          assets of ESI taken as a whole, including all machinery and
          equipment, are, in all material respects, in good condition and
          repair, reasonable wear and tear excepted and have been well
          maintained.  ESI does not own, nor have any right to acquire, any
          real property.

                     3.12  Employees.  Schedule 3.12 contains a complete 
                           ---------   -------------
          and correct list of (i) all full-time and part-time employees of
          ESI, including their respective salaries, dates of hire,
          positions and last salary adjustment and (ii) all bonus, deferred
          compensation, severance or termination pay, insurance, medical,
          dental, drug, profit sharing, pension, retirement, stock option,
          stock purchase, hospitalization insurance or other material plans
          or arrangements providing employee benefits to any current or
          former director, officer, employee or consultant of ESI and all
          relevant vacation policies.  ESI is not a party to any union,
          collective bargaining or similar agreement, and there are no
          controversies pending or, to ESI's knowledge, threatened between
          ESI and any current or former employee or any labor or other
          collective bargaining unit representing any current or former
          employee of ESI that could reasonably be expected to result in a
          material labor strike, dispute, slow-down or work stoppage or
          otherwise have a material adverse effect on the financial
          condition of ESI.  ESI is not aware of any organizational effort
          presently being made or threatened by or on behalf of any labor
          union with respect to employees of ESI.  ESI has paid or accrued
          in full all wages, salaries, commissions, bonuses and other
          compensation (including severance pay and vacation benefits) for
          all services performed by its employees and former employees, and
          has withheld such amounts as were required to be withheld
          therefrom and has paid the withheld amounts to the proper tax and
          other receiving officers within the time required under
          applicable law. ESI does not have any benefit plan subject to the
          reporting requirements of the Employee Retirement Income Security
          Act of 1974, as amended ("ERISA"), the Code and other applicable
          Laws, nor has had such a plan since January 1, 1996.

                     3.13  Insurance.  Schedule 3.13 contains a complete 
                           ---------   -------------
          and correct schedule of coverage and list of all policies of
          insurance owned by ESI under which ESI assets, properties,
          operations or employees are insured (including amount of
          coverage, type of insurance, amount of deductible, if any, the
          policy number and expiration date), and all claims made under any
          of such policies or prior policies since December 31, 1996. 
          Since December 31, 1996, ESI has given due and timely notice of
          any claim and of any occurrence known to ESI which may be covered
          by any of such policies or prior policies.  All scheduled
          policies are in full force and effect and are in amounts and
          coverage sufficient for compliance by ESI with all applicable
          requirements of Law and all agreements to which ESI is a party or
          subject and customary in its industry.  All premiums in
          connection with such policies are fully paid.  No event has
          occurred which, with notice or lapse of time, would constitute a
          breach or default thereunder or permit termination, modification
          or acceleration of any policy, and no party to any policy has
          repudiated any provisions thereof.

                     3.14  Inventories. The amounts at which the 
                           -----------
          inventories are carried on the ESI Interim Balance Sheet and on
          the books of ESI reflect the normal valuation policy of ESI in
          accordance with GAAP.  The amount of repair parts and supplies
          maintained by ESI is consistent with its prior practices.  The
          reserves estimated for obsolescence as of the Closing Date will
          be adequate to cover the diminution in value of inventories due
          to obsolescence.

                     3.15  Accounts Receivable.  Schedule 3.15 sets forth a
                           -------------------   -------------

          receivable of ESI as set forth on the ESI Interim Balance Sheet,
          including the degree of completion for each project and the
          amounts expended thereon.  All accounts receivable which have
          arisen subsequent to the ESI Interim Balance Sheet represent
          sales or work performed made in the ordinary course of business,
          are current and collectible and, to ESI's knowledge, the same
          will be collected in full (net of reserve for bad debts) in the
          ordinary course of business and are not subject to any claims,
          offsets, allowances or adjustments.

                     3.16  Intellectual Property.  Schedule 3.16 is a

          registrations of or pending applications for any of the
          foregoing), know-how, databases, trade secrets and
          confidentiality information (collectively, "Intellectual
          Property") used by ESI in the conduct of its business.  Except as
          disclosed on Schedule 3.16:
                       -------------

          ESI free and clear of all liens, and is not subject to any
          license, royalty or other agreement;

                     (b)   none of such Intellectual Property has been or
          is the subject of any pending or, to the best of ESI's knowledge,
          threatened litigation or claim of infringement;

                     (c)   no license or royalty agreement to which ESI is
          a party is in breach or default by any party thereto except where
          such breach or default would not have an ESI Material Adverse
          Effect or is the subject of any notice of termination given or,
          to ESI's knowledge, threatened;

                     (d)   to ESI's knowledge, ESI is not breaching or
          infringing any Intellectual Property of third parties; and

                     (e)   the Intellectual Property is sufficient for the
          conduct of the business of ESI as presently conducted.

                     3.17  Environmental Matters.  The business and 
                           ---------------------

          remedial action is required to respond to a release or threatened

          business is conducted.  ESI has performed its services for

          Environmental Laws.

          and correct minutes of all meetings of its directors committees
          and stockholders.  The ESI Articles of Incorporation and By-laws
          previously delivered to AEC are current and complete.  At the
          Closing Date, all of those books and records will be in the
          possession of ESI.  Schedule 3.18 sets forth a complete and

          employment agreements included on another ESI Schedule to this
          Agreement and benefits given to all employees of ESI).  All
          transactions and agreements listed on Schedule 3.19 were on terms

                              ACQUISITION CORP. AND AEC

                     Acquisition Corp. and AEC, jointly and severally,

          respectively, with all requisite power and authority to own,
          lease and operate its properties and to carry on its business as
          now being conducted.  AEC is qualified to do business and is in
          good standing as a foreign corporation in each jurisdiction where
          the nature of the properties owned, leased or operated by it and
          the business transacted by it require such qualification, except
          where the failure to be so qualified could not have an AEC
          Material Adverse Effect (as defined in Section 4.7 herein).
                                                 -----------

                     4.2   Due Authorization.  Each of AEC and Acquisition

          proceedings on the part of Acquisition Corp. or its stockholder
          are necessary to authorize this Agreement.  Each of AEC and
          Acquisition Corp. has duly and validly executed and delivered
          this Agreement.  This Agreement constitutes the legal, valid and
          binding obligations of each of AEC and Acquisition Corp.,
          enforceable in accordance with its terms, except as such
          enforceability may be limited by applicable bankruptcy,
          insolvency, fraudulent transfer, moratorium, reorganization or
          other laws from time to time in effect which affect creditors'
          rights generally and by general principles of equity (regardless
          of whether such enforceability is considered in a proceeding in
          equity or at law).

                     4.3   Non-Contravention; Consents and Approvals.

          conflict with, result in a violation or breach of, constitute
          (with or without notice or lapse of time or both) a default
          under, result in or give to any person any right of payment or
          reimbursement, termination, cancellation, modification or
          acceleration of, or result in the creation or imposition of any
          lien upon any of the assets or properties of any of the AEC

             authorities.

                     4.5   Financial Statements; Undisclosed Liabilities; 
                           ---------------------------------------------- 
          Other Documents.  (a)  For purposes of this Agreement, "AEC 
          ---------------
          Financial Statements" shall mean (x) the audited consolidated
          financial statements of AEC as of July 31, 1997 and July 27, 1996
          and for the fiscal years then ended (including all notes thereto)
          and (y) the unaudited consolidated financial statements of AEC as
          of January 31, 1998 and January 25, 1997 and for the six months
          then ended consisting of the consolidated balance sheets at such
          dates and the related consolidated statements of operations,
          stockholders' equity and cash flows for the periods then ended
          which are included in the AEC SEC Documents (as defined in
          Section 4.6).  The AEC Financial Statements have been prepared in
          -----------
          accordance with GAAP consistently applied, present fairly the
          financial position, of AEC as at the dates thereof and the
          results of operations and cash flows of AEC for the periods
          covered thereby (subject, in the case of any unaudited interim
          financial statements, to normal year-end adjustments), and are
          substantially in accordance with the financial books and records
          of AEC.

                           (b)     AEC does not have any liabilities or
          obligations of any nature, whether accrued, contingent, absolute
          or otherwise, which individually or in the aggregate could be
          reasonably expected to have an AEC Material Adverse Effect (as
          defined below) except (i) as set forth in the January 31, 1998
          balance sheet (the "AEC Interim Balance Sheet") or (ii)
          liabilities or obligations incurred since January 31, 1998 in the
          ordinary and usual course of its business.

                     4.6   Securities Law Filings.  AEC is a subject to the
                           ----------------------
          reporting requirements of Section 12 of the Securities Exchange
          Act of 1934, as amended (the "Exchange Act"), and has filed all
          required forms, reports and other documents with the U.S.
          Securities and Exchange Commission (the "SEC") since July 28,
          1996, all of which complied when filed, in all material respects,
          with all applicable requirements of the Exchange Act.  AEC has
          heretofore delivered to ESI complete and correct copies of (i)
          its Annual Report on Form 10-KSB for the year ended July 31,
          1997, (ii) its Form 10-QSB for the quarter ended January 31,
          1998, and (iii) all other reports, forms and other documents
          filed by AEC with the SEC since July 27, 1996 (together, the "AEC
          SEC Documents").

                     4.7   No Material Adverse Effects or Changes.  Except
                           --------------------------------------
          as listed on Schedule 4.7, or as disclosed in or reflected in the
                       ------------
          AEC Financial Statements included in the AEC SEC Documents, or as
          contemplated by this Agreement, since January 31, 1998, neither
          AEC nor any of its wholly-owned subsidiaries (AEC and such
          subsidiaries sometimes collectively, the "AEC Companies") has
          suffered any damage, destruction or Loss to any of its assets or
          properties (whether or not covered by insurance) which is having
          or could be expected to have an AEC Material Adverse Effect.  An
          "AEC Material Adverse Effect" shall mean an effect on or
          circumstances involving the business, operations, assets,
          liabilities, results of operations, cash flows or condition
          (financial or otherwise) which is materially adverse to the AEC
          Companies, taken as a whole.

                     4.8   Insurance.  The AEC Companies are insured with 
                           ---------
          reputable insurers against all risks and in such amounts normally
          insured against by companies of the same type and in the same
          line of business as the AEC Companies.

                    4.9  Labor Matters.  Each of the AEC Companies has 
                         -------------
          conducted and currently is conducting, its respective business in
          full compliance with all laws relating to employment and
          employment practices, terms and conditions of employment, wages
          and hours and nondiscrimination in employment except where such
          failure to be in compliance would not have an AEC Material
          Adverse Effect.  The relationship of the AEC Companies with their
          respective employees is generally satisfactory, and there is, and
          during the past three years there has been, no labor strike,
          dispute, slow-down, work stoppage or other labor difficulty
          pending or, to AEC's knowledge, threatened against or involving
          the AEC Companies.  None of the employees of the AEC Companies
          are covered by any collective bargaining agreement, no collective
          bargaining agreement is currently being negotiated by the AEC
          Companies and to AEC's knowledge, no attempt is currently being
          made or during the past three years has been made to organize any
          employees of the AEC Companies to form or enter a labor union or
          similar organization.

                    4.10 Tax Returns and Audits.  Except as set forth on 
                         ----------------------
          Schedule 4.10, each of the AEC Companies has duly filed all 
          -------------
          United States, state, local and foreign Tax Returns required to
          be filed by it, except where the failure to so file would not
          have an AEC Material Adverse Effect.  AEC has duly paid (except
          for Taxes being contested in good faith) or made adequate
          provisions on its books in accordance with GAAP for the payment
          of all Taxes which have been incurred or are due and payable, by
          the AEC Companies, and AEC will on or before the Effective Time
          of the Merger make adequate provision on its books in accordance
          with GAAP for all Taxes payable for any period through the
          Effective Time of the Merger for which no return is required to
          be filed prior to the Effective Time.  Since July 31, 1996, the
          Tax Returns of the AEC Companies have not been examined by the
          IRS or other taxing authority, nor has any of the AEC Companies
          granted or given any extensions or waivers of the statute of
          limitations with respect to any such federal and state income tax
          returns since July 31, 1996.  AEC is not aware of any basis for
          the assertion of any deficiency against any of the AEC Companies
          for Taxes, which, if adversely determined, would have an AEC
          Material Adverse Effect.

                    4.11 Litigation.  (a)  There are no actions, suits, 
                         ----------
          arbitrations, regulatory proceedings or other litigation,
          proceedings or governmental investigations pending or, to AEC's
          knowledge, threatened against or affecting any of the AEC
          Companies or any of their respective officers or directors in
          their capacity as such, or any of their respective properties or
          businesses which could reasonably be expected to have an AEC
          Material Adverse Effect.  No AEC Company is subject to any order,
          judgment, decree, injunction, stipulation or consent order of or
          with any court or other Governmental Entity, other than orders of
          general applicability.

                    (b)  There are no claims, actions, suits, proceedings,
          or investigations pending or, to AEC's knowledge, threatened by
          or against any of the AEC Companies with respect to this
          Agreement, or in connection with the transactions contemplated
          hereby or thereby.

                    4.12 Compliance with Applicable Laws.  Each of the AEC
                         -------------------------------
          Companies holds all permits, licenses, variances, exemptions,
          orders and approvals of all Governmental Entities which are
          required in the operation of its respective business (the "AEC
          Permits") except for those the failure of which to hold would not
          have an AEC Material Adverse Effect.  The AEC Companies are in
          compliance with the terms of the AEC Permits, except where the
          failure so to comply would not have an AEC Material Adverse
          Effect.  None of the AEC Companies is in violation of any law,
          ordinance or regulation of any Governmental Authority, including
          environmental laws and regulations, except for possible
          violations which individually and in the aggregate do not, and,
          insofar as reasonably can be foreseen by AEC, will not in the
          future have an AEC Material Adverse Effect.

                    4.13 Contracts; No Defaults.  Neither any AEC Company 
                         ----------------------
          nor to AEC's knowledge any other party thereto, is in breach or
          violation of, or in default in the performance or observance of
          any term or provision of, and no event has occurred or by reason
          of this Agreement or the Merger would occur which, with notice or
          lapse of time or both, could be reasonably expected to result in
          a default under, any contract, agreement or commitment to which
          any AEC Company is a party or by which any AEC Company or any of
          its assets or properties is bound, except for breaches,
          violations and defaults which are not having and could not be
          reasonably expected to have an AEC Material Adverse Effect.  None
          of the AEC Companies is required to give any notice to any person
          regarding this Agreement or the transactions contemplated hereby
          or thereby.

                    4.14 Fees of Brokers, Finders and Investment Bankers. 
                         -----------------------------------------------
          Neither AEC nor any officer, director, or employee of AEC has
          employed any brokers, finder or investment banker or incurred any
          liability for any brokerage or investment banking fees,
          commissions or finders' fees in connection with the transactions
          contemplated by this Agreement.

                    4.15 General Representation and Warranty.  Neither this
                         -----------------------------------
          Agreement nor any schedule attached hereto or other documents and
          written information furnished by or on behalf of AEC, its
          attorneys, auditors or insurance agents to ESI in connection with
          this Agreement contains any untrue statement of material fact or
          omits to state any material fact necessary to make the statements
          contained herein or therein not misleading.

          Confidentiality.  (a)  From and after the date of this Agreement,
          ---------------
          ESI shall give AEC and Acquisition Corp. and their
          representatives access during normal business hours and upon
          reasonable notice to all of the facilities, properties, books,
          contracts, commitments and records of ESI and shall make the
          officers and employees of ESI available to AEC and Acquisition
          Corp. and their representatives as AEC or Acquisition Corp. or
          their representatives shall from time to time reasonably request. 
          AEC and Acquisition Corp. and their representatives will be
          furnished with any and all information concerning ESI which AEC
          or Acquisition Corp. or their representatives reasonably request. 
          The obligations set forth in this Section 5.2 shall also apply to

                                     ------- --------
          by and knowledge of ESI or AEC and the furnishing of information
          to each other shall not affect the right of such party to rely on

          other party hereto.

                    (b)  Each of ESI, on one hand, and AEC and Acquisition
          Corp., on the other hand, agrees for itself, and its respective
          representatives, to keep confidential all information furnished

          is public or which is disclosed other than by a person subject to
          this Section 5.2(b).

                    5.3  Preservation of Business.  (a) From the date of 
                         ------------------------
          this Agreement until the Closing Date, each of ESI and AEC,
          (including the ESI Companies and the other AEC Companies,
          respectively) shall operate only in the ordinary and usual course
          of business consistent with past practice, and shall use
          reasonable commercial efforts to (i) preserve intact its business
          organization, (ii) preserve the good will and advantageous
          relationships with customers, suppliers, independent contractors,
          employees and other persons material to the operation of its
          business, and (iii) not permit any action or omission which would
          cause any of the representations or warranties contained herein

          any material respect.

                    (b)  ESI further covenants that prior to the Closing
          Date ESI shall not, nor permit any of the ESI Companies to,

                    (i)  take any action, incur any obligation or enter
          into or authorize any contract or transaction other than in the

          in writing upon becoming aware of any fact or condition which
          would constitute a breach or non-compliance of this covenant.

                    5.4  ESI Stockholder Approval.  As soon as practicable
                         ------------------------
          after the date hereof, ESI shall prepare a proxy statement for a
          stockholders meeting (the "ESI Stockholders Meeting") at which
          irrevocable approval of this Agreement and the Merger will be
          voted upon.  ESI will convene the ESI Stockholders Meeting as

          Subject to fiduciary obligations of the ESI Board of Directors,
          the ESI Board of Directors shall recommend approval to its

          shall furnish to ESI such information regarding AEC and
          Acquisition Corp. as may reasonably be necessary for inclusion in
          the proxy statement.  ESI agrees to provide AEC with drafts of
          the proxy statement at least two business days prior to
          distribution of the final proxy statement to ESI stockholders.

                    5.5  Consents and Approvals.  Subject to the terms and
                         ----------------------
          conditions provided herein, each of the parties hereto shall use
          reasonable commercial efforts to obtain all consents, approvals,
          certificates and other documents required in connection with the
          performance by it of this Agreement and the consummation of the
          transactions contemplated hereby, in addition to the approval of
          ESI Stockholders.  As soon as practicable after the date hereof,
          each of the parties hereto shall make all filings, applications,
          statements and reports to all Governmental Authorities and other
          Persons which are required to be made prior to the Closing Date
          pursuant to any applicable law or contract in connection with
          this Agreement and the transactions contemplated hereby.

          announcement or statement with respect to the transactions
          contemplated hereby and prior to making any filing with any
          federal or state governmental or regulatory agency with respect
          thereto, AEC and ESI will, subject to their respective legal
          obligations, consult with each other and will allow each other to
          review the contents of any such public announcement or statement
          and any such filing.  Subject to the preceding sentence, AEC and
          ESI each agree to furnish to the other copies of all other public
          announcements they may make concerning their respective business
          and operations promptly after such public announcements are made.

                    5.8  No Negotiation.  ESI agrees that it shall not, 
                         --------------
          after the date hereof and prior to the Effective Time, seek,
          directly or through agents, representatives or affiliates (as
          defined in the Exchange Act), or permit any of its officers or
          directors to seek (whether in their capacities as officers or
          directors or in their individual capacities) any person or
          persons, (other than AEC), to acquire or purchase all or
          substantially all of its assets or to purchase or exchange for
          any of its capital stock, or ESI to acquire or purchase in one or
          more related transactions the capital stock or related assets of
          persons (other than AEC or its affiliates) or to effect a
          consolidation or merger (other than the Merger) or other business
          combination or recapitalization, or to enter into any agreements
          with respect to any of the foregoing transactions, and shall
          cease any such discussions held with third parties (other than
          AEC) as of the date hereof.

                         ------------------
          necessary state securities law or "blue sky" permits and
          approvals required to carry out the transactions contemplated by
          this Agreement and the Merger.

                    5.11 Status of ESI Stockholders as Accredited 
                         ----------------------------------------
          Investors.  Each holder of ESI Common Stock immediately prior to
          ---------
          the Closing Date shall represent to AEC, by means of an
          acknowledged questionnaire or other means acceptable to AEC, that
          as of the Effective Time such holder is or is not an "accredited
          investor" as such term is defined in Rule 501 of Regulation D
          promulgated under the Securities Act of 1933, as amended (the
          "Securities Act"), and the other representations as set forth on
          Exhibit B annexed hereto.

                    5.12 Registration Rights.  (a) Registration.  AEC will
                         -------------------       ------------
          use its best efforts, within six (6) months from the Effective
          Date, to file a registration statement (the "Registration
          Statement") on Form SB-2 or such other applicable form under the
          Securities Act with the Securities and Exchange Commission (the
          "Commission") to register the Firm Shares including any
          additional shares pursuant to Section 1.4(c) or (d) hereof (the 
                                        ---------------------
          "Registered Shares"), for sale and use its best efforts to cause
          the Registration Statement to be declared effective and to
          maintain the Registration Statement under the Securities Act from
          its effective date until the earlier of (A) one (1) year after
          the Effective Date or (B) all Registered Shares included therein
          have been sold.  AEC may include the Registered Shares in a
          registration statement being filed by AEC with respect to other
          securities of AEC.  AEC shall give written notice to each ESI
          Holder at least twenty (20) days prior to filing the Registration
          Statement asking such Holder how many of his shares of AEC Common
          Stock he wants to include in the Registration Statement.  If an
          ESI Holder fails to timely advise AEC in writing of the number of
          shares of AEC Common Stock he wants to include in the
          Registration Statement, he shall have no further rights to have
          his shares of AEC Common Stock included therein.  The obligation
          of AEC under this provision shall be limited to one Registration
          Statement which becomes effective under the Securities Act.

                    (b)  Registration Procedures. (i)  AEC shall pay all 
                         -----------------------
          expenses of the Registration Statement filed pursuant to this
          Section, including, without limitation, all registration, filing
          and qualification fees, printing expenses, fees and disbursements
          of counsel for AEC, accounting fees incidental to or required by
          such registration; provided, however, that each ESI Holder shall
                             --------  -------
          pay all underwriting discounts and commissions applicable to his
          Registered Shares and fees and disbursements of his own attorney. 
          AEC shall furnish the ESI Holders such number of copies of a
          prospectus, including a preliminary prospectus, to the
          Registration Statement as the ESI Holders may reasonably request.

                    (ii) In connection with any Registration Statement
          filed pursuant to this Section, AEC shall file any post-effective
          amendment or amendments to the Registration Statement which may
          be required under the Securities Act during the period reasonably
          required to effect the distribution contemplated thereby.

                    (iii)  Each ESI Holder who desires to include his
          shares of AEC Common Stock in the Registration Statement must
          enter into a Selling Stockholders Agreement with AEC regarding
          the relative rights and duties of the Selling Stockholders and
          AEC, including customary indemnification provisions.

                    (iv) AEC shall not be required to include in any
          Registration Statement any Registered Shares if in the opinion of
          counsel to AEC, registration of the Registered  Shares proposed
          to be included is not required under the Securities Act if such
          Registered Shares may then be publicly sold in accordance with
          Section 4(1) thereof and Rule 144 thereunder.

                    (c)  State Securities Laws.  In connection with the 
                         ---------------------
          offering of any Registered Common Stock pursuant to this Section,
          AEC shall use its best efforts to qualify or register the
          Registered Shares under the securities or "Blue Sky" laws of such
          jurisdictions as may be reasonably requested by the Holders.

          deficiencies, costs and expenses (including without limitation,
          all reasonable legal and other professional fees and
          disbursements, interest, penalties and amounts paid in
          settlement) (collectively, "Claims") arising out of, based upon
          or by reason of (A) any breach of any representation or warranty
          of ESI contained in this Agreement or in any Schedule or
          certificate delivered pursuant to this Agreement or (B) any
          breach or non-fulfillment of, or failure to perform, any of the
          covenants, agreements or understandings of ESI which are
          contained in or made pursuant to this Agreement.

                    (b)  Notwithstanding anything to the contrary herein,
          any claim by AEC against the ESI Holders under this Section 9.1 
                                                              -----------
          shall be payable by the ESI Holders only to the extent that AEC's
          damages (the "Damages") shall exceed in the aggregate $25,000
          (the "Threshold Amount").  At such time as the aggregate amount
          of AEC Damages exceed the Threshold Amount, the ESI Stockholders
          shall be liable on a dollar-for-dollar basis for the full amount
          of all AEC Damages, including the Threshold Amount.  Any payments
          to be made by the ESI Stockholders under this Section 9.1 shall 
                                                        -----------
          be from shares of AEC Common Stock and/or funds held under the
          Escrow Agreement, and shall be pro-rata based upon their 
                                         --------
          respective ownership of ESI Common stock as of immediately prior
          to the Effective Time.  In no event shall the aggregate liability
          of the ESI Holders under this Section 9.1 exceed the amount of 
                                        -----------               
          funds and/or shares of AEC Common Stock and/or funds ($360,000)
          held under the Escrow Agreement.

                    9.2  Indemnification by AEC
                         ----------------------
                    (a)  AEC shall indemnify and hold harmless the ESI
          Holders (the "Indemnified Stockholders") from and against any
          claims, demands, debts, suits, actions, obligations, proceedings,
          losses, damages, liabilities, deficiencies, costs and expenses
          (including without limitation, all reasonable legal and other
          professional fees and disbursements, interest, penalties and
          amounts paid in settlement) (collectively, "Claims") arising out
          of, based upon or by reason of (A) any breach by AEC of any
          representation or warranty by AEC contained in this Agreement or
          (B) any breach or non-fulfillment of, or failure to perform, any
          of the covenants, agreements or undertakings of AEC which are
          contained in or made pursuant to this Agreement.  It is
          acknowledged that the person who is acting as the agent of the
          Indemnified Stockholders pursuant to the Escrow Agreement shall
          also act as agent on behalf of the Indemnified Stockholders
          pursuant to this Section 9.2 (the "Stockholders' Agent").
                           -----------

                    (b)  Notwithstanding anything to the contrary herein,
          any claim by the Indemnified Stockholders against AEC under this
          Section 9.2 shall be payable by AEC only to the extent that the 
          -----------
          Indemnified Stockholders damages ("Damages") shall exceed the
          Threshold Amount.  At such time as the aggregate amount of the
          Indemnified Stockholders Damages exceed the Threshold Amount, AEC
          shall thereafter be liable on a dollar-for-dollar basis for the
          full amount of all Indemnified  Stockholders Damages, including
          the Threshold Amount.  AEC may make payments of amounts payable
          under this Section 9.2 in U.S. currency and/or shares of AEC
          Common Stock, which shares be valued at the Average Closing Price
          per share for the five trading days immediately prior to the
          payment date, as provided in the Escrow Agreement.  In no event
          shall the aggregate liability of AEC under this Section 9.2
          exceed $360,000.

                    9.3  Procedure.  (a) Any Claim brought by AEC or the 
                         ---------
          ESI Stockholders under this ARTICLE IX must be in writing,
          specifying the nature of the Claim and the estimated amount of
          damages, and be received by the party against whom
          indemnification is being sought within one year after the
          Effective Date (the "Indemnity Termination Date").

                    (b)  In the event that subsequent to the Effective
          Time, and prior to the Indemnity Termination Date, AEC receives
          written notice of the assertion of a claim or the commencement of
          any action or proceeding by any person who is not a party to this
          Agreement (including any Governmental Entity) (a "Third Party
          Claim"), against AEC, ESI or one of their affiliates against
          which AEC may be entitled to indemnification hereunder, AEC shall
          give written notice of the Third Party Claim to the Stockholders'
          Agent.  AEC shall have the right to conduct the defense of the
          Third Party Claim, and the cost of such defense shall be part of
          AEC Damages.  If an offer is made to settle a Third Party Claim
          and AEC desires to accept such offer, AEC shall give written
          notice of the offer of settlement to the Stockholders' Agent who
          shall have fifteen (15) days from receipt thereof to accept or
          reject the offer, which rejection must be on a reasonable basis. 
          The failure of the Stockholders Agent to respond to a desired
          offer of settlement shall be deemed acceptance thereof.

                    9.4  Remedies.  Each of AEC and Acquisition Corp, on 
                         --------
          one hand, and ESI (until the Effective Time) and the ESI
          Stockholders (after the Effective Time), on the other hand, shall
          not be liable or responsible in any manner whatsoever to the
          other, whether for indemnification or otherwise, with respect to
          any matter arising out of the representations, warranties or
          covenants of this Agreement or any Schedule hereto or any
          certificate delivered in connection herewith except for (i)
          equitable relief, (ii) pursuant to remedies expressly provided
          for elsewhere in this Agreement and (iii) indemnity as expressly
          provided in this ARTICLE IX, all of which provide the exclusive
          remedy of the parties hereto.

          American Electromedics Signs Merger Agreement with Equidyne
          Systems Inc., Developer of New "Needle-Free Injector" Delivery
          Technology


          April 1, 1998 03:30 PM

          AMHERST, N.H.--(BUSINESS WIRE)--April 1, 1998--



          Patented, FDA Approved Technology Addresses Estimated $2 Billion
          Annual Market
                                                                          

          American Electromedics Corporation ('AMER') and its President,
          Michael Pieniazek, announced today that it has signed a merger
          agreement to acquire Equidyne Systems Inc., a developer of
          medical products based in San Diego, Calif. Upon completion of
          the merger, AMER will issue approximately 600,000 shares of its
          common stock to the shareholders of Equidyne. The merger is
          expected to be completed during the second calendar quarter of
          1998 and the closing is contingent upon the completion of due
          diligence, and obtaining all necessary consents and other
          customary closing conditions. 

          Equidyne Systems Inc. is a development company that owns a
          patented product for needle-free drug  injection which features a
          lightweight, portable injector pen with a disposable medication
          ampule. The product is designed to replace a standard needle
          syringe. Equidyne has received FDA 510(k) market clearance
          approval. This new and innovative technology is designed to
          provide an effective, economical, safe and essentially pain-free
          injection method. Equidyne expects to be able to deliver
          commercial quantities of the product by late 1998. All key
          managers are expected to sign long-term employment
          agreements with AMER.

          Michael Pieniazek, president of AMER stated, "This merger will
          give AMER a patented, new technology to add to its portfolio of
          medically related product offerings. The "needleless needle"
          addresses an enormous market opportunity in a time when
          infectious disease and inadvertent contamination are major
          issues."

          Equidyne's core technology can be used for many different drug
          delivery regiments and allows for needle-free injection into
          either the subcutaneous or intra-muscular tissue. There are many
          uses for this product including the physician's office, hospital
          and clinics, vaccine inoculations and self administered
          injections by people with diabetes, allergies and other ailments.

          AMER currently develops, manufactures and markets intraoral
          dental camera systems and other diagnostic audiometric medical
          devices in the United States and worldwide. The company is
          committed to brining to the medical community products and
          superiority.

           This press release contains forward looking formation based upon
          current expectations that include a number of business risks and
          uncertainties. The factors that could cause results to differ
          materially include the following: delays in closing the merger or
          termination of the Merger Agreement, lack of market acceptance of
