          Item 5.   Other Events.
          _______   _____________

                    On February 21, 1996, Advanced NMR Systems, Inc.
          ("Advanced NMR") filed a Current Report on Form 8-K disclosing
          that a securities class action complaint (the "Original
          Complaint") was filed against it in the Court of Chancery of the
          State of Delaware in connection with a merger (the "Merger")
          between a wholly-owned subsidiary of Advanced NMR and Advanced
          Mammography Systems, Inc., a Delaware corporation ("AMS").

                    On February 28, 1996, a related complaint (Civil Action
          No. 14866) was filed in Delaware state court by Susan Kaufman
          (the "Kaufman Complaint") seeking substantially similar relief to
          that sought in the Original Complaint on substantially similar
          grounds.  The Kaufman Complaint names three additional defendants
          not named in the Original Complaint:  John A. Lynch, a director
          of Advanced NMR, and Joseph DeRose and Bernard Weiner, each a
          director of AMS.

                    According to both complaints, Advanced NMR and the
          named directors breached their fiduciary duties to the public
          stockholders of AMS in approving the Merger for inadequate
          consideration to such stockholders.  As with the Original
          Complaint, Advanced NMR believes there is no basis for the claims
          made by plaintiff, and the company intends to vigorously defend
          the action.

                    The Kaufman Complaint is included as Exhibit 99 hereto.

                    Section 1.  Annual Meeting.  The annual meeting of the

                                ______________

           stockholders of ADVANCED NMR SYSTEMS, INC. (hereinafter called

          the "Corporation") for the election of directors and for the

          transaction of such other proper business as may come before the

          meeting shall be held at such date, time and place, either within

          or without the State of Delaware, as shall be designated by the

          Board of Directors from time to time.

                    Section 2.  Special Meetings.  Special meetings of the

                                ________________

           stockholders for any purpose or purposes may be called at any

          time by the Board of Directors or the Chairman of the Board, but

          special meetings may not be called by any other person or

          persons.  The only business to be conducted at a special meeting

          of stockholders shall be as specified in the notice of such

          meeting.

                    Section 3.  Notice of Meetings; Adjournments.  Notice

                                ________________________________

           of the date, time and place of the holding of each annual and

          special meeting of stockholders and, in the case of a special

          meeting, the purpose or purposes thereof, shall be given

          personally or by mail in a postage prepaid envelope to each

          stockholder entitled to vote at such meeting, not less than ten

          nor more than sixty days before the date of such meeting, and, if

          mailed, it shall be directed to such stockholder at his address

          as it appears on the records of the Corporation, unless he shall

          have filed with the Secretary of the Corporation, a written

          request that notices to him be mailed to some other address, in

          which case it shall be directed to him at some other address.  If

          mailed such notice shall be deemed to be delivered when deposited

          in the United States mail so addressed with postage thereon

          prepaid.  Any meeting of stockholders, annual or special, may be

          adjourned from time to time to reconvene at the same or some

          other place, and notice need not be given of any such adjourned

          meeting if the time and place thereof are announced at the

          meeting at which the adjournment is taken.

                    Section 4.  Quorum.  Except as otherwise provided by

                                ______

           law, the Certificate of Incorporation or these By-laws, at each

          meeting of stockholders the presence in person or by proxy of the

          holders of shares of stock having a majority of the votes which

          could be cast by the holders of all outstanding shares of stock

          entitled to vote at the meeting shall be necessary and sufficient

          to constitute a quorum.  In the absence of a quorum the

          stockholders so present may, by majority vote, adjourn the

          meeting from time to time in the manner provided in Article I,

          Section 3 of these By-laws until a quorum shall attend.  Shares

          of its own stock belonging to the Corporation or to another

          corporation, if a majority of the shares entitled to vote in the

          election of directors of such other corporation is held, directly

          or indirectly, by the Corporation, shall neither be entitled to

          vote nor be counted for quorum purposes; provided, however, that

          the foregoing shall not limit the right of the Corporation to

          vote stock, including but not limited to its own stock, held by

          it in a fiduciary capacity.

                    Section 5.  Organization.  Meetings of stockholders

                                ____________

           shall be presided over by the Chairman of the Board, or in his

          absence by the Vice Chairman of the Board, or in his absence by

          the President, or in his absence by a Vice President, or in the

          absence of the foregoing persons by a chairman designated by the

          Board of Directors, or in the absence of such designation by a

          chairman chosen at the meeting.  The Secretary shall act as

          secretary of the meeting, but in his absence the chairman of the

          meeting may appoint any person to act as secretary of the

          meeting.  The Chairman of the meeting shall announce at the

          meeting of stockholders the date and time of the opening and

          closing of the polls for each matter upon which the stockholders

          will vote.

                    Section 6.  Voting; Proxies.  Except as otherwise

                                _______________

           provided by the Certificate of Incorporation, each stockholder

          entitled to vote at any meeting of stockholders shall be entitled

          to one vote for each share of stock held by him which has voting

          power upon the matter in question.  Each stockholder entitled to
          
          vote at a meeting of stockholders may authorize another person or

          persons to act for him by proxy, but no such proxy shall be voted

          or acted upon after three years from its date, unless the proxy

          provides for a longer period.  A proxy shall be irrevocable if it

          states that it is irrevocable and if, and only as long as, it is

          coupled with an interest sufficient in law to support an

          irrevocable power.  A stockholder may revoke any proxy which is

          not irrevocable by attending the meeting and voting in person or

          by filing an instrument in writing revoking the proxy or by

          delivering a proxy in accordance with applicable law bearing a

          later date to the Secretary of the Corporation.  Voting at

          meetings of stockholders other than the election of directors

          need not be by written ballot and, unless otherwise required by

          law, need not be conducted by inspectors of election unless so

          determined by the Board of Directors, the chairman of the meeting

          or by the holders of shares of stock having a majority of the

          votes which could be cast by the holders of all outstanding

          shares of stock entitled to vote thereon which are present in

          person or by proxy at such meeting.  At all meetings of

          stockholders for the election of directors a plurality of the

          votes cast of shares present in person or represented by proxy at

          the meeting and entitled to vote for the election of directors

          shall be sufficient to elect directors.  All other elections and

          questions shall, unless otherwise provided by law, the

          Certificate of Incorporation or these By-laws, be decided by the

          affirmative vote of the majority of shares of stock present in

          person or represented by proxy at the meeting and entitled to

          vote on the subject matter.

                    Section 7.  Fixing Date for Determination of

                                ________________________________

           Stockholders of Record.  In order that the Corporation may

           ______________________

           determine the stockholders entitled to notice of or to vote at

          any meeting of stockholders or any adjournment thereof, or

          entitled to receive payment of any dividend or other distribution

          or allotment of any rights, or entitled to exercise any rights in

          respect of any change, conversion or exchange of stock or for the

          purpose of any other lawful action, the Board of Directors may

          fix a record date.  The record date shall not precede the date

          upon which the resolution fixing the record date is adopted by

          the Board of Directors.  The record date:  (1) in the case of

          determination of stockholders entitled to vote at any meeting of

          stockholders or adjournment thereof, shall unless otherwise

          required by law not be more than sixty nor less than ten days

          before the date of such meeting; and (2) in the case of any other

          action, shall not be more than sixty days prior to such other

          action.  If no record date is fixed:  (1) the record date for

          determining stockholders entitled to notice of or to vote at a

          meeting of stockholders shall be at the close of business on the

          day next preceding the day on which notice is given, or if notice

          is waived, at the close of business on the day next preceding the

          day on which the meeting is held; and (2) the record date for

          determining stockholders for any other purpose shall be at the

          close of business on the day on which the Board of Directors

          adopts the resolution relating thereto.  A determination of

          stockholders of record entitled to notice of or to vote at a

          meeting of stockholders shall apply to any adjournment of the

          meeting; provided, however, that the Board of Directors may fix a

          new record date for the adjourned meeting.

                    Section 8.  List of Stockholders Entitled To Vote.  The

                                _____________________________________

           Secretary shall prepare and make, at least ten days before every

          meeting of stockholders, a complete list of the stockholders

          entitled to vote at the meeting, arranged in alphabetical order,

          and showing the address of each stockholder and the number of

          shares registered in the name of each stockholder.  Such list

          shall be open to the examination of any stockholder, for any

          purpose germane to the meeting, during ordinary business hours,

          for a period of at least ten days prior to the meeting, either at

          a place within the city where the meeting is to be held, which

          place shall be specified in the notice of the meeting, or if not

          so specified, at the place where the meeting is to be held.  The

          list shall also be produced and kept at the time and place of the

          meeting during the whole time thereof and may be inspected by a 

          stockholder who is present.  Upon the willful neglect or refusal

          of the directors to produce such a list at any meeting for the

          election of directors, they shall be ineligible for election to

          any office at such meeting.  The stock ledger shall be the only

          evidence as to who are the stockholders entitled to examine the

          stock ledger, the list of stockholders or the books of the

          Corporation, or to vote in person or by proxy at any meeting of

          stockholders.

                    Section 9.  Conduct of Meetings.  The Board of

                                ___________________

           Directors of the Corporation may adopt by resolution such rules

          and regulations for the conduct of the meeting of stockholders as

          it shall deem appropriate.  Except to the extent inconsistent

          with such rules and regulations as adopted by the Board of

          Directors, the chairman of any meeting of stockholders shall have

          the right and authority to prescribe such rules, regulations and

          procedures and to do all such acts, in the judgment of such

          chairman, as are appropriate for the proper conduct of the

          meeting.  Such rules, regulations or procedures, whether adopted

          by the Board of Directors or prescribed by the chairman of the

          meeting, may include, without limitation, the following:  (i) the

          establishment of an agenda or order of business for the meeting;

          (ii) rules and procedures for maintaining order at the meeting

          and the safety of those present; (iii) limitations on attendance

          at or participation in the meeting to stockholders of record of

          the Corporation, their duly authorized and constituted proxies or

          such other persons as the chairman of the meeting shall

                                 ______________________________________

           At an annual meeting of the stockholders, only such business

          shall be conducted as shall have been properly brought before the

          meeting.  To be properly brought before an annual meeting

          business must be:  (a) specified in the notice of meeting (or any

          supplement thereto) given by or at the direction of the Board of

          Directors, (b) otherwise properly brought before the meeting by

          or at the direction of the Board of Directors, or (c) otherwise

          properly brought before the meeting by a stockholder.  For

          business to be properly brought before an annual meeting by a

          stockholder, the stockholder must have given timely notice

          thereof in writing to the Secretary of the Corporation.  To be

          timely, a stockholder's notice must be delivered to or mailed and

          received at the principal executive offices of the Corporation,

          not less than 60 days nor more than 90 days prior to the meeting;

          provided, however, that in the event that less than 70 days'

          notice or prior public disclosure of the date of the meeting is

          given or made to stockholders, notice by the stockholder to be

          timely must be so received not later than the close of business

          on the 10th day following the day on which such notice of the

          date of the annual meeting was mailed or such public disclosure

          was made.  A stockholder's notice to the Secretary shall set

          forth as to each matter the stockholder proposes to bring before

          the annual meeting (a) a brief description of the business

          desired to be brought before the annual meeting and the reasons

          for conducting such business at the annual meeting, (b) the name

          and address, as they appear on the Corporation's books, of the

          stockholder proposing such business, (c) the class and number of

          shares of the Corporation which are beneficially owned by the

          stockholder, and (d) any material interest of the stockholder in

          such business.  Notwithstanding anything in the By-Laws to the

          contrary, no business shall be conducted at any annual meeting

          except in accordance with the procedures set forth in this

          Section 10.  The chairman of the annual meeting shall, if the

          facts warrant, determine and declare to the meeting that business

          was not properly brought before the meeting and in accordance

          with the provisions of this Section 10, and if he should so

          determine, he shall so declare to the meeting and any such

          business not properly brought before the meeting shall not be

          transacted.

          by any stockholder of the Corporation entitled to vote for the

          election of directors at the meeting who complies with the notice

          procedures set forth in this Section 15.  Such nominations, other

          than those made by or at the direction of the Board of Directors,

          shall be made pursuant to timely notice in writing to the

          Secretary of the Corporation.  To be timely, a stockholder's

          notice shall be delivered to or mailed and received at the

          principal executive offices of the Corporation not less than 60

          days or more than 90 days prior to the meeting; provided,

          however, that in the event that less than 70 days' notice or

          prior public disclosure of the date of the meeting is given or

          made to stockholders, notice by the stockholder to be timely must

          be so received not later than the close of business on the 10th

          day following the day on which such notice of the date of the

          meeting was mailed or such public disclosure was made.  Such

          the stockholder proposes to nominate for election or re-election

          as a director, (i) the name, age, business address and residence

          address of such person, (ii) the principal occupation or

          employment of such person, (iii) the class and number of shares

          of the Corporation which are beneficially owned by such person

          and (v) any other information relating to such person that is

          required to be disclosed in solicitations of proxies for election

          of directors, or is otherwise required, in each case pursuant to

          Regulation 14A under the Securities Exchange Act of 1934, as

          amended (including without limitation such persons' written

          consent to being named in the proxy statement as a nominee and to

          serving as a director if elected); and (b) as to the stockholder

          giving the notice (i) the name and address, as they appear on the

          Corporation's books, of such stockholder and (ii) the class and

          number of shares of the Corporation which are beneficially owned

          by such stockholder.  At the request of the Board of Directors

          any person nominated by the Board of Directors for election as a

          director shall furnish to the Secretary of the Corporation that

          information required to be set forth in a stockholder's notice of

          nomination which pertains to the nominee.  No person shall be

          eligible for election as a director of the Corporation unless

          nominated in accordance with the procedures set forth in this

          Section 15.  The chairman of the meeting shall, if the facts

          warrant, determine and declare to the meeting that a nomination

          was not made in accordance with the procedures prescribed by the

          By-Laws, and if he should so determine, he shall so declare to

          the meeting and the defective nomination shall be disregarded.

                                   _______________

                    Section 1.  Right to Indemnification.  The Corporation

                                ________________________

           shall indemnify any person who was or is a party or is

          threatened to be made a party to any threatened, pending or

          completed action, suit or proceeding, whether civil, criminal,

          administrative or investigative (other than an action by or in

          the right of the Corporation) by reason of the fact that he is or

          was a director of the Corporation, or is or was serving at the

          request of the Corporation as a director, officer, employee or

          agent of another corporation, partnership, joint venture, trust,

          or other enterprise, against expenses (including attorneys'

          fees), judgments, fines and amounts paid in settlement actually

          and reasonably incurred by him in connection with such action,

          suit or proceeding if he acted in good faith and in a manner he

          reasonably believed to be in or not opposed to the best interests

          of the Corporation, and, with respect to any criminal action or

          proceeding, had no reasonable cause to believe his conduct was

          unlawful.

           may, in its discretion, pay the expenses (including attorneys'

          fees) incurred in defending any proceeding in advance of its

          final disposition, provided, however, that the payment of

          expenses incurred by a director or officer in advance of the

          final disposition of the proceeding shall be made only upon

          receipt of an undertaking by the director or officer to repay all

          amounts advanced if it should be ultimately determined that the

          director or officer is not entitled to be indemnified under this

          Article or otherwise.  Such expenses (including attorneys' fees)

          incurred by other employees and agents may be so paid upon such

          terms and conditions, if any, as the Board of Directors deems

          appropriate.

                                ______

           payment of expenses under this Article is not paid in full

          within sixty days after a written claim therefor has been

          received by the Corporation, the claimant may file suit to

          recover the unpaid amount of such claim and, if successful in

          whole or in part, shall be entitled to be paid the expense of

          prosecuting such claim.  In any such action the Corporation shall

          have the burden of proving that the claimant was not entitled to

          the requested indemnification or payment of expenses under

          applicable law.  

                    Section 4.  Non-Exclusivity of Rights.  The rights

                                _________________________

           conferred on any person by this Article V shall not be exclusive

          of any other rights which such person may have or hereafter

          acquire under any statute, provision of the Certificate of

          Incorporation, these By-laws, agreement, vote of stockholders or

          disinterested directors or otherwise.

                                ________________________________

          was or is serving at its request as a director, officer, employee

          or agent of another corporation, partnership, joint venture,

          trust, or other enterprise shall be reduced by any amount such

          person may collect as indemnification from such other

          corporation, partnership, joint venture, trust, or other

          enterprise.  The Corporation may purchase and maintain insurance

          on behalf of any person who is or was a director, officer,

          employee or agent of the Corporation, or is or was serving at the

          request of the Corporation as a director, officer, employee or

          agent of another corporation, partnership, joint venture, trust,

          or other enterprise against any liability asserted against him in

          any such capacity, or arising out of his status as such, whether

          or not the Corporation would have the power to indemnify him

          against such liability under the provisions of law or this

          section.

                                ___________________

           modification of the foregoing provisions of this Article V shall

          not adversely affect any right or protection hereunder of any

          person in respect of any act or omission occurring prior to the

          time of such repeal or modification.

          shall allege to have been lost, stolen, or destroyed or which

          shall have been mutilated.  The Board may, in its discretion,

          require such owner or his legal representative to give the

          Corporation a bond in such sum, limited or unlimited, and in such

          form and with such surety or sureties as the Board in its

          absolute discretion shall determine, to indemnify the Corporation

          against any claim that may be made against it on account of the

          alleged lost, theft, or destruction of any such certificate, or

          the issuance of a new certificate.

                                CLASS ACTION COMPLAINT
                               ______________________

               Plaintiff, by and through her attorneys, alleges upon

          information and belief, except as to paragraph 2, which she

          alleges upon personal knowledge, as follows: 



                                 NATURE OF THE ACTION

                                 ____________________

               1.   This is a stockholders' class action on behalf of the

          public stockholders of Advanced Mammography Systems, Inc. ("AMS"

          or the "Company"), against certain officers and directors and the

          controlling shareholder of AMS to enjoin certain actions of the

          defendants related to the acquisition of the outstanding shares
          
          of AMS common stock by its majority controlling shareholder,

          defendant Advanced NMR Systems, Inc. ("NMR").

                                     THE PARTIES

                                     ___________

               2.   Plaintiff Susan Kaufman has been at all times relevant

          to the action,  and continues to be, an owner of 500 shares of

          AMS common stock.

               3.   Defendant AMS is a corporation duly organized and

          existing under the laws of the State of Delaware, with its

          principal executive offices located at 46 Jonspin Road,

          Wilmington, Massachusetts.  AMS is a development-stage company

          which was organized to acquire and develop proprietary technology

          from NMR in order to design, manufacture, and commercialize a

          dedicated magnetic resonance imaging ("MRI") system for breast

          imaging which can be used in the detection of breast tissue

          abnormalities and aid in the diagnosis of breast cancer.

               4.   Defendant NMR is also a Delaware corporation with its

          principal executive offices located at 46 Jonspin Road,

          Wilmington, Massachusetts.  NMR develops and manufactures

          ultrafast MRI technology for clinical applications and advanced

          research.  NMR owns 61% of the outstanding shares of AMS and, as

          controlling shareholder of AMS, owes fiduciary obligations of

          good faith, candor, loyalty  and fair dealing to the public

          minority shareholders of AMS.
               
               5.   Defendant Jack Nelson ("Nelson") is and has been at all

          relevant times the Chairman of AMS.  In addition, Nelson serves

          as the Chairman and Treasurer of NMR.

               6.   Defendant Robert Spira ("Spira") is and has been at all

          relevant times the Vice Chairman of AMS.  In addition, Spira is

          and has been at all relevant times the Vice Chairman and a

          director of NMR.

               7.   Defendants George Aaron, George A. Silver, Sol

          Triebwasser and John A. Lynch are and have been at all relevant

          times directors of AMS and NMR.  Defendants Gary A. Kittrell,

          Joseph DeRose and Bernard Weiner are and have been at all

          relevant times directors of AMS (collectively, with defendants

          Nelson and Spira, the "Individual Defendants").  

               8.   By virtue of their positions as directors and/or

          officers of AMS and/or their exercise of control and dominant

          ownership over the business and corporate affairs of AMS, each

          and every of the Individual Defendants and NMR have, and at all

          relevant times had, the power to control and influence, and did

          control and influence AMS and cause it to engage in the practices

          complained of herein.  Each Individual Defendant and NMR owed and

          owes AMS and its stockholders fiduciary obligations and were and

          are required to:  use their ability to control and manage AMS in

          a fair, just and equitable manner; act in furtherance of the best

          interests of AMS and its stockholders; refrain from abusing their

          positions of control; and refrain from favoring their own

          interests at the  expense of AMS and its stockholders.

               9.   As discussed in detail below, NMR and the Individual

          Defendants, who control the actions of AMS, have breached their

          fiduciary duties to AMS's public stockholders by attempting to

          acquire the publicly-held minority shares of AMS for unfair and

          inadequate consideration.

               10.  Each defendant herein is sued individually as a

          conspirator and aider and abettor, and in the case of the

          Individual Defendants, in their capacity as directors and/or

          officers of AMS.  The liability of each arises from the fact that

          they have engaged in all or part of the unlawful acts, plans,

          schemes, or transactions complained of herein.



                               CLASS ACTION ALLEGATIONS

                              ________________________

               11.  Plaintiff brings this action on behalf of herself and

          as a class action,  pursuant to Rule 23 of the Rules of the Court

          of Chancery, on behalf of all other public stockholders of AMS

          (excluding defendants herein and any person, firm, trust,

          corporation, or other entity related to or affiliated with any of

          them and their successors  in interest), who are or will be

          threatened with injury arising from defendants' actions as more

          fully described herein (the "Class"). 

               12.  This action is properly maintainable as a class action

          for the following reasons: 

                    (a)  The Class of stockholders for whose benefit this

          action is brought is  so numerous that joinder of all members is

          impracticable.  As of March 15, 1995, AMS had approximately 6.5

          million shares of common stock outstanding, collectively held by

          approximately 77 stockholders of record and many beneficial

          owners.  Members of the Class are scattered throughout the United

          States.

                    (b)  There are questions of law and fact which are

          common to the Class  and which predominate over questions

          affecting any individual Class member, including whether the

          defendants have breached the fiduciary duties owed by them to

          plaintiff and other members of the Class by reason of the acts

          described herein.

                    (c)  Plaintiff's claims are typical of the claims of

          the Class in that all members of the Class will be damaged by the

          defendants' actions.

                    (d)  Plaintiff is committed to the vigorous prosecution

          of this action and has retained competent counsel experienced in

          litigation of this nature.  Plaintiff is an adequate

          representative of the Class and anticipates that there will not

          be any difficulty in the management of this litigation as a class

          action.

                    (e)  The prosecution of separate actions by individual

          members of the  Class would create a risk of inconsistent or

          varying adjudications with respect to individual members of the

          Class which would establish incompatible standards of conduct for

          the party opposing the Class.

                    (f)  Defendants have acted and will continue to act on

          grounds generally  applicable to the Class, thereby making

          appropriate, inter alia, final injunctive or corresponding

                       _____ ____

           declaratory relief with respect to the Class as a whole.



                               SUBSTANTIVE ALLEGATIONS

                               _______________________

               13.  Except for skin cancer, which has a low mortality rate,

          breast cancer strikes women more frequently than any other form

          of cancer.  Breast cancer is second to lung cancer in the number

          of cancer deaths among women.

               14.  In the United States, National Cancer Institute

          guidelines recommend that women over 50 undergo an annual

          screening for breast cancer.  Screening exams which result in

          early detection of the disease lead to increased survival rates

          among breast cancer patients.  Approximately 25 million screening

          procedures were performed in 1995, generally utilizing

          conventional x-ray and ultrasound equipment.

               15.  However, screening x-ray mammography results in

          ambiguous or indeterminate findings in 15-20% of the patients

          tested.  

               16.  MRI imaging, a well-established technique, provides

          medical images for the diagnosis and detection of disease.  The

          systems use magnets, digital computers and controlled radio waves

          to derive cross-sectional (two-dimensional) and volume (three-

          dimensional) pictures of human anatomy, which can be displayed

          either on film or a video monitor.  MRI imaging provides

          information about the concentration and the  physical and

          chemical environment of atomic nuclei within the body, without

          the need for invasive surgery.  Furthermore, MRI does not use

          ionizing radiation, thus, it is relatively risk-free.

               17.  Current commercially available MRI systems are whole

          body scanners, which are very large and expensive for discrete

          uses such as breast imaging.  Accordingly, AMS was organized in

          July 1992 to design, manufacture, and commercialize a dedicated

          (or partial body) MRI system for breast imaging which can be used

          to detect and characterize breast tissue abnormalities.

               18.  In January 1993, AMS completed a public offering of

          1,483,500 shares of common stock at $6.00 per share.  The

          offering proceeds were used for the repayment of debt, for

          research and development and for working capital.

               19.  On April 15, 1994, defendant Nelson stated

          affirmatively:  "we believe that the market for MR mammography is

          already forming, and that Advanced Mammography Systems will be a

          premier provider of such systems."

               20.  On June 24, 1994, AMS announced at its annual meeting

          of shareholders that it had successfully obtained images with

          components used on its dedicated MRI mammography system.  William

          H. Voorheis, President and Chief Operating Officer, stated:

                    This is an epic milestone for the Company.  The
                    successful imaging of our dedicated MR mammography
                    system is the first step to delivering MR technology
                    for breast imaging at greatly reduced cost while
                    improving breast cancer detection.

               21.  In February 1995, AMS filed a 501(k) application with

          the U.S. Food and Drug Administration (the "FDA") seeking

          clearance for commercial sale and use of its Aurora dedicated MR

          Breast Imaging System.

               22.  On September 28, 1995, AMS announced that it had

          entered an agreement with the University of Texas Medical Branch

          at Galveston ("UTMB") for its first Aurora system installation -

          for clinical evaluation at UTMB's Breast Imaging Center.

               23.  In connection with the UTMB announcement, Peter B.

          Roemer, Ph.D., executive vice president of research and

          technology for AMS stated:

                    The Aurora system was designed for patient comfort and
                    user-friendly operation, as well as maximum image
                    resolution.  We are confident it will ultimately become
                    an important tool in more accurately diagnosing breast
                    disease for high risk women for whom conventional x-ray
                    mammography is insufficient.

          According to NMR's most recent 10-K, "the unit will be shipped to

          the University's Breast Imaging Clinic in February 1996." 

               24.  NMR's 1995 10-K also stated that:  "AMS is negotiating

          with several other breast imaging centers to establish additional

          beta test sites for this product and is engaged in pre-market

          activities to educate potential customers about the products

          capabilities."

               25.  AMS is thus poised for substantial future growth and

          profitability.  Reflecting its promising prospects, its stock

          traded as high as $15 per share as recently as June 1995.
               
               26.  In contrast, NMR, according to its most recent 10-K,

          realized a net loss  of $1,677,758 or $.07 per share for the nine

          months ended September 30, 1995.  

               27.  On February 5, 1996, AMS and NMR announced that they

          had entered into a definitive merger agreement (the "Agreement"). 

          Pursuant to the Agreement, the two companies would merge in a

          stock swap transaction and AMS shareholders would receive $2.625

          in NMR common stock for each AMS share, subject to certain

          conditions.

               28.  AMS and NMR further announced that the actual number of

          NMR shares to be issued for each AMS share will be determined by

          dividing $2.625 by the average closing price of NMR common stock

          over a 30 day trading period ending five days prior to the

          closing of the transaction, up to a limit of 1.297059 NMR shares

          for each share of AMS common stock.  Therefore, the number (and

          value) of NMR shares to be received is capped.

               29.  The Agreement is timed to take advantage of the

          Company's severely  depressed share price, which is currently

          well below its 52-week high of $15 1/4.  Moreover, the Company

          will soon realize the substantial benefits of its much-touted

          Aurora system, which has not yet been fully reflected in the

          price of AMS's stock.  NMR has breached its fiduciary duties by

          failing to offer consideration to the Company's minority

          shareholders which takes into account the future financial

          prospects of the Company's products as well as its important

          new-product developments.

               30.  Furthermore, in 1992, AMS was granted by NMR a

          perpetual, worldwide  exclusive, royalty-free license for all of

          NMR's proprietary technology if useful in connection with

          developing a dedicated MRI system for mammography (the "Field of

          Use").  Additionally, AMS has been granted a 50% interest in any

          entity which may be organized by NMR to develop dedicated use MRI

          scanners outside the Field of Use and a 50% interest in any net

          profits derived by NMR from the sale or license of dedicated use

          MRI systems based on information outside the Field of Use.  By

          virtue of the Agreement, NMR seeks effectively to rescind its

          licensing agreement and appropriate to its exclusive use AMS's

          lucrative corporate opportunity.

               31.  By reason of its position as a majority stockholder of

          AMS, NMR is in possession of non-public information concerning

          AMS, which it and the Individual Defendants have not disclosed to

          AMS's public stockholders.

               32.  The proposed merger offer to AMS's public stockholders

          does not represent the true value of the Company and is

          unconscionable, unfair and grossly inadequate and constitutes

          unfair dealing.

               33.  The proposed transaction will deny class members their

          right to share proportionately in the true value of AMS's

          valuable and profitable business, and future growth in profits

          and earnings, at a time when the Company is poised to

          dramatically increase its profitability.

               34.  Defendants' fiduciary obligations require them to:

                    (a)  act independently so that the interests of AMS's

          public stockholders will be protected;

                    (b)  adequately ensure that no conflicts of interest

          exist between defendants' own interests and their fiduciary

          obligation of entire fairness or, if such conflicts exist, to

          ensure that all the conflicts are resolved in the best interests

          of AMS's public stockholders; and 

                    (c)  provide AMS stockholders with independent

          representation in the negotiations with NMR.

               35.  Because NMR controls over 60% of AMS, no auction or

          market check can be effected to establish AMS's worth through

          arms-length bargaining.  Thus, NMR has the power and is

          exercising its power to acquire AMS's minority shares and dictate

          terms which are in NMR's best interest, without competing bids

          and regardless of the wishes or best interests of the Class

          members.

               36.  Defendants' purported review of the transaction by a

          special committee of AMS's "independent directors" which,

          according to defendants, has reviewed the agreement and found it

          to be fair to the Company's shareholders from a financial point

          of view, is insufficient.  As stated above, each of AMS's

          directors, with the exception of defendants Kittrell, DeRose and

          Weiner, is also a director and/or officer of NMR.  Defendants

          Kittrell, DeRose and Weiner are dependent upon the remaining

          directors and NMR for their positions as directors and the

          substantial benefits that result from that position.  In

          addition, all of the AMS directors have intermingled personal and

          business relationships.  Thus, each of the Individual Defendants

          suffers from disabling conflicts of interest in that their desire

          to remain entrenched in their positions at AMS and advance the

          interests of NMR are in conflict with their obligation to

          maximize shareholder value and secure fair value for AMS's

          minority shareholders.

               37.  The AMS Board, dominated and controlled by individuals

          and entities whose ownership interests predated the public

          offering, have agreed to the proposed transaction because their

          desire is to convert their AMS investment at this time, at a

          substantial premium over their cost, notwithstanding that class

                                   _____

           members will be receiving substantially less than they paid in

          the public offering and in the open market.  Moreover, the public

          minority was induced to purchase AMS stock based upon the

          long-term value of their investment as touted in the Prospectus.

               38.  By reason of the foregoing, defendants have violated

          the fiduciary duties which each of them owes to plaintiff and the

          other members of the Class.

               39.  Each of the defendants has rendered substantial

          assistance in the accomplishment of the wrongdoing complained of

          herein.  In taking the actions, as particularized herein, to aid

          and abet and substantially assist the wrongs complained of, all

          defendants acted with an awareness of the primary wrongdoing and

          realized that their  conduct would substantially assist the

          accomplishment of that wrongdoing and were aware of their overall

          contribution to the conspiracy, common scheme and course of

          wrongful conduct.

               40.  By reason of the foregoing, defendants have wrongfully

          participated in unfair dealing toward the members of the Class

          and have engaged in and have substantially assisted and aided and

          abetted each other in breaching fiduciary duties owed to

          plaintiff and other members of the Class.

               41.  By virtue of the acts and conduct alleged herein, NMR

          and the Individual Defendants are not complying with their

          fiduciary duties and are carrying out a preconceived plan and

          scheme to advance NMR's interests at the expense of AMS's public

          shareholders.

               42.  Unless enjoined by this Court, defendants will continue

          to breach their fiduciary duties owed to plaintiff and the other

          members of the Class, and may consummate the proposed

          transaction, which will exclude the Class from its fair

          proportionate share of AMS's valuable products and businesses,

          all to the irreparable harm of the Class, as aforesaid.

               43.  Plaintiff and the other Class members are immediately

          threatened by the acts and transactions complained of herein,

          which have caused and will cause them irreparable injury.

               44.  Plaintiff and the Class have no adequate remedy at law.
                
               WHEREFORE, plaintiff demands judgment and preliminary and

          permanent relief, including injunctive relief, in her favor and

          in favor of the Class and against defendants as follows:

                    A.   Declaring that this action is properly

          maintainable as a class action, and certifying plaintiff as a

          class representative;

                    B.   Declaring that the defendants and each of them

          have committed or participated in a gross abuse of trust and have

          breached their fiduciary duties to plaintiff and other members of

          the Class or aided and abetted such breaches;

                    C.   Enjoining the proposed transaction and, if the

          transaction is consummated, rescinding the transaction;

                    D.   Awarding plaintiff and the Class compensatory

          damages and/or rescissory damages;

                    E.   Awarding plaintiff the costs and disbursements of

          this action, including allowance for reasonable plaintiff's

          attorneys' and experts' fees; and 

                    F.   Granting such other, and further relief as this

          Court may deem to be just and proper.
