          Item 5.   Other Events.
          ------    ------------

                    As of May 15, 1996, Advanced Mammography Systems, Inc.
          (the "Registrant") closed a private placement (the "Placement")
          of $3 million principal amount of 4% Convertible Debentures of
          the Registrant (the "Debentures") due December 1, 1998 (the
          "Maturity Date").

                    The Debentures accrue interest at the rate of 4% per
          annum from the date of issuance to the Maturity Date, or earlier
          either upon conversion or prepayment.  Upon conversion, the
          Registrant has the option to pay the accrued interest on the
          Debentures being converted in shares of its Common Stock at the
          then conversion rate.

                    A Debentureholder may, at his election, convert at all
          or part of his Debentures at any time (a) commencing 45 days
          after the closing as to one-half (1/2) of the principal amount of
          his Debentures, and (b) commencing 60 days after the closing as
          to the balance of his Debentures into shares of the Registrant's
          Common Stock at a conversion price equal to the lesser of (i)
                                                          ------
          125% of the Market Price on the closing, or (ii) 75% of the
          Market Price on the date of conversion, subject to customary
          anti-dilution provisions.  The Market Price is defined as the
          average closing bid price of the Common Stock for the three
          trading days immediately preceding the closing or conversion
          date, as may be applicable, as reported on the NASDAQ system (or
          the closing bid price for the applicable day if the Common Stock
          is traded on the over-the-counter market or on an exchange).  In
          the event that during the period commencing June 1, 1997, the per
          share price of the Common Stock exceeds $4.00 for five trading
          days during any ten day period, the Registrant may, upon three
          days written notice, elect to convert the Debentures into shares
          of Common Stock at the applicable conversion rate as of the date
          of notice.

                     Assuming a conversion price based on the average
          closing bid price of the Registrant's Common Stock on the NASDAQ
          System for the three trading days immediately preceding May 15,
          1996, and the conversion of all of the Debentures, the Registrant
          would issue 1,442,308 shares of its Common Stock.

                    The Placement was offered and sold outside the United
          States to non-U.S. persons pursuant to an exemption from the
          registration requirements of the Securities Act of 1933 available
          under Regulation S promulgated thereunder.  The Debentures will
          not be registered and may not be offered or sold in the United
          States absent such registration or an applicable exemption from
          the registration requirements of the Securities Act.

                    The net proceeds of the Placement of approximately
          $2,750,000, after payment of fees and related expenses, will be
          used for completion of product development of the Registrant's
          dedicated MR breast imaging "Aurora" system, the
          commercialization and marketing of the Aurora system and working
          capital.  Management believes that the net proceeds should be
          sufficient to meet the Company's operating needs for the next 12
          months.  

                    The Placement was effected pursuant to Offshore
          Securities Subscription Agreements (the "Subscription Agreement")
          entered into between the Registrant and each of the subscribers. 
          A form of Subscription Agreement (without exhibits) is included
          as an Exhibit hereto.

                    In connection with the Placement, the Registrant issued
          to the placement agents for the Debentures warrants for the
          purchase of 197,500 shares of the Registrant's Common Stock at an
          exercise price of $2.20 per share for a period of eighteen (18)
          months and warrants for an additional 197,500 shares of the
          Common Stock at an exercise price of $2.50 per share for a period
          of five years.   

                    Upon the closing of the placement, the Registrant and
          Advanced NMR Systems, Inc. ("ANMR") which owns 61% of the
          outstanding Common Stock of the Registrant, terminated a
          previously announced Agreement and Plan of Merger, dated as of
          February 4, 1996, providing for the merger (the "Merger") of AMS
          Merger Corporation, a wholly-owned subsidiary of ANMR, with and
          into the Registrant.  

                    On May 16, 1996, the Registrant issued a press release
          announcing the closing of the Placement and the termination of
          the Merger Agreement.  A copy of such press release is included
          as an exhibit hereto.

                    4% CONVERTIBLE DEBENTURE DUE December 1, 1998


              THIS DEBENTURE is one of a duly authorized issue of
          $3,000,000 in Debentures of ADVANCED MAMMOGRAPHY SYSTEMS, INC., a
          corporation duly organized and existing under the laws of the
          State of Delaware (the "Company") designated as its 4%

               FOR  VALUE   RECEIVED,  the  Company  promises   to  pay  to
          ___________________________,  the  registered holder  hereof (the
          "Holder"),  the principal  sum of  __________________________ (US
          $____________) on December  1, 1998 (the "Maturity  Date") and to
          pay interest on the  principal sum outstanding from time  to time
          in  arrears on  December 1,  1998, at  the rate  of 4%  per annum
          accruing  from the date of initial issuance.  Accrual of interest
          shall commence on the first such business day to occur after  the
          date hereof until payment in  full of the principal sum  has been
          made or  duly provided for.  All interest so payable will be paid
          to  the person  in  whose name  this Debenture  (or  one or  more
          predecessor  Debentures)  is registered  on  the  records of  the
          Company  regarding registration  and transfers of  the Debentures
          (the "Debenture Register") on the tenth day prior to the Maturity
          Date,  provided,  however, that  the  Company's  obligation to  a
          transferee of this  Debenture arises only if such  transfer, sale
          or other disposition  is made  in accordance with  the terms  and
          conditions of the Regulation S Subscription Agreement executed by
          the original Holder.  Subject to the provisions of  4 below,  the
          principal of, and interest on, this Debenture are payable in such
          coin or currency  of the United States of America  as at the time
          of  payment is  legal tender  for payment  of public  and private
          debts, at the address last appearing on the Debenture Register of
          the Company  as designated in writing by  the Holder from time to
          time.   The Company will  pay the principal  of and interest upon
          this Debenture on the Maturity Date, less any amounts required by
          law to be deducted, to the registered holder of this Debenture as
          of the tenth day prior to the Maturity Date and addressed to such
          holder as  the last address appearing on  the Debenture Register.
          The  forwarding  of  such check  shall  constitute  a  payment of
          interest hereunder and shall  satisfy and discharge the liability
          for principal and interest on this Debenture to the extent of the
          sum represented by such check plus any amounts so deducted.

               This  Debenture  is  subject  to  the  following  additional
               provisions:

               1.   The Debentures  are issuable in denominations  of Fifty
          Thousand Dollars  (US$ 50,000)  and  integral multiples  thereof.
          The Debentures are exchangeable  for an equal aggregate principal
          amount of  Debentures of  different authorized denominations,  as
          requested  by the  Holders  surrendering the  same.   No  service
          charge  will  be  made  for  such  registration  or  transfer  or
          exchange.

               2.   The Company shall be entitled to withhold from all
          payments of principal of, and interest on, this Debenture any
          amounts required to be withheld under the applicable provisions
          of the United States income tax laws or other applicable laws at
          the time of such payments, and Holder shall execute and deliver
          all required documentation in connection therewith.

               3.   This  Debenture has  been issued subject  to investment
          representations  of  the original  purchaser  hereof  and may  be
          transferred or  exchanged only in compliance  with the Securities
          Act of 1933, as  amended (the "Act"), and other  applicable state
          and  foreign securities  laws.   In  the  event of  any  proposed
          transfer of  this Debenture,  the Company  may require,  prior to
          issuance of  a new Debenture  in the  name of such  other person,
          that  it  receive  reasonable  transfer  documentation  including
          opinions  that the issuance of  the Debenture in  such other name
          does  not  and will  not  cause a  violation  of the  Act  or any
          applicable  state  or foreign  securities  laws.   Prior  to  due
          presentment for transfer of this  Debenture, the Company and  any
          agent of  the Company  may treat  the person  in whose  name this
          Debenture is duly registered  on the Company's Debenture Register
          as  the  owner hereof  for the  purpose  of receiving  payment as
          herein provided and for  all other purposes, whether or  not this
          Debenture  be overdue, and neither the Company nor any such agent
          shall be affected by notice to the contrary.

               4.   The  Holder  of  this  Debenture is  entitled,  at  its
          option,  to convert at  any time  (a) commencing  forty-five (45)
          days  after the  closing  of  the  sale  of  the  Debenture  (the
          "Closing"),  one-half  (1/2)  of  the principal  amount  of  this
          Debenture, and (b) commencing sixty  (60) days after the Closing,
          the balance of the  principal amount of this  Debenture, provided
          that the principal  amount is at  least US $50,000 (unless  if at
          the  time of  such election  to  convert the  aggregate principal
          amount  of all Debentures registered  to the Holder  is less than
          Fifty  Thousand  Dollars  (US  $50,000), then  the  whole  amount
          thereof),  into  shares  of Common  Stock  of  the  Company at  a
          conversion  price for  each share  of Common  Stock equal  to the
          lesser of  (a) 125% of  the Market Price  on the Closing,  or (b)
          seventy-five (75%) percent of the  Market Price on the Conversion
          Date.  For purposes of this Section 4, the Market  Price shall be
          the  average closing bid  price of the Common  Stock on the three
          (3) trading days immediately  preceding the Closing or Conversion
          Date,  as  may   be  applicable,  as  reported  by  the  National
          Association  of  Securities  Dealers Automated  Quotation  System
          ("NASDAQ"),  or the   closing bid  price on  the over-the-counter
          market  on such date or, in the  event the Common Stock is listed
          on a stock exchange, the Market Price shall be the  closing price
          on  the exchange on  such dates, as  reported in the  Wall Street
          Journal.   Conversion  shall be  effectuated by  surrendering the
          Debentures  to be  converted  to the  Company  with the  form  of
          conversion notice attached  hereto as Exhibit A, executed  by the
          Holder  of the  Debenture evidencing  such Holder's  intention to
          convert this Debenture or a specified portion (as above provided)
          hereof,  and accompanied, if  required by the  Company, by proper
          assignment hereof in  blank.  Interest  accrued or accruing  from
          the date  of issuance  to the  date of  conversion shall,  at the
          option  of  the Company,  be paid  in kind  upon conversion.   No
          fraction of Shares or scrip representing fractions of shares will
          be  issued on conversion, but the number of shares issuable shall
          be rounded  to the nearest whole share.  The date on which notice
          of conversion is given (the "Conversion Date") shall be deemed to
          be the date  on which  the Holder has  delivered this  Debenture,
          with the conversion notice  duly executed, to the Company  or, if
          earlier, the  date set forth in such  notice of conversion if the
          Debenture is  received by the  Company within three  (3) business
          days  therefrom.   Facsimile  delivery of  the conversion  notice
          shall be accepted by  the Company at telephone number  (201) 592-
          0393.   Certificates representing  Common  Stock upon  conversion
          will  be delivered within three  (3) business days  from the date
          the notice of conversion  and this Debenture is delivered  to the
          Company.

               5.   No provision  of this  Debenture shall alter  or impair
          the   obligation  of   the   Company,  which   is  absolute   and
          unconditional, to  pay the  principal of,  and interest  on, this
          Debenture  at the  time,  place, and  rate,  and in  the  coin or
          currency,  herein  proscribed.    This Debenture  and  all  other
          Debentures  now or hereafter  issued of similar  terms are direct
          obligations of the  Company.  This  Debenture ranks equally  with
          all  other Debentures,  excluding conventional,  institutional or
          secured debt.

               6.   No  recourse shall  be  had  for  the  payment  of  the
          principal  of, or  the interest  on, this  Debenture, or  for any
          claim based hereon, or  otherwise in respect hereof,  against any
          incorporator, shareholder,  officer or  director, as  such, past,
          present or future,  of the Company or any  successor corporation,
          whether by virtue of any constitution, statute or rule of law, or
          by the enforcement of any assessment or penalty or otherwise, all
          such liability being, by the acceptance hereof and as part of the
          consideration  for   the  issue  hereof,  expressly   waived  and
          released.

               7.   The number  of Shares  issuable upon the  conversion of
          the Debenture (the "Exercise Rate") is subject to adjustment from
          time to time as set forth in this Section 7.

                    (a)  Adjustment for Change in Capital Stock.  If the

                         (i)    subdivides its outstanding shares of Common
          Stock into a greater number of shares;

                         (ii)    combines its outstanding  shares of Common
          Stock into a smaller number of shares; or

                         (iii)    issues by reclassification  of its Common
          Stock  any shares  of its  Capital Stock  (as defined  in Section
          (e));

          then the Exercise Rate in effect immediately prior to such action
          shall  be adjusted so that the registered Holder of the Debenture
          thereafter exercised may  receive the number of shares  of Common
          Stock or Capital  Stock of  the Company which  such Holder  would
          have owned immediately  following such action if  such Holder had
          converted  the Debenture immediately  prior to such  action.  The
          adjustment shall become effective immediately after the effective
          date of any subdivision, combination or reclassification.

                    (b)  Notice of Adjustment.  Whenever the Exercise Rate
                         --------------------
          is  adjusted, the  Issuer shall  mail to  the Debenture  holder a
          notice of such event.

                    (c)  No Other Adjustment for Dividends.  Except as
                         ---------------------------------
          provided  in this  Section  7, no  adjustment  will be  made  for
          dividends on any Common Stock.

                    (d)  Multiple Adjustments.  After an adjustment to the
                         --------------------
          Exercise  Rate  under  this   Section  7,  any  subsequent  event
          requiring  an adjustment  under  this Section  7  shall cause  an
          adjustment to the Exercise Rate as so adjusted.

                    (e)  Definitions.
                         -----------

                         "Capital Stock" means, with respect to any
                         ---------------
          corporation, any  and all shares, interests,  rights to purchase,
          warrants, options,  participation's or  other  equivalents of  or
          interests   (however  designated)   in  stock   issued  by   that
          corporation.

               8.   If  the  Company merges  or  consolidates with  another
          corporation or sells or transfers all or substantially all of its
          assets to another person and the holders of the Common  Stock are
          entitled  to receive stock, securities  or property in respect of
          or  in exchange  for Common  Stock, then  as a condition  of such
          merger, consolidation, sale or transfer, the Company and any such
          successor, purchaser or transferee  shall amend this Debenture to
          provide  that it  may thereafter  be converted  on the  terms and
          subject  to  the conditions  set forth  above  into the  kind and
          amount  of stock,  securities  or property  receivable upon  such
          merger, consolidation, sale or transfer by a holder of the number
          of  shares of Common Stock  into which this  Debenture might have
          been  converted  immediately before  such  merger, consolidation,
          sale or transfer, subject to adjustments which shall be as nearly
          equivalent as may be  practicable.  In the event  of any proposed
          merger, consolidation or sale or transfer of all or substantially
          all of  the assets of the  Company (a "Sale"), the  Holder hereof
          shall  have  the  right to  convert  by  delivering  a Notice  of
          Conversion  to the Company within fifteen (15) days of receipt of
          notice of  such Sale from the  Company.  In the  event the Holder
          hereof shall elect  not to  convert, the Company  may prepay  all
          outstanding principal  and accrued  interest  on this  Debenture,
          less  all  amounts required  by law  to  be deducted,  upon which
          tender of payment following such notice, the  right of conversion
          shall terminate.

               9.   The  Holder of  the  Debenture, by  acceptance  hereof,
          agrees that this Debenture  is being acquired for  investment and
          that such Holder  will not  offer, sell or  otherwise dispose  of
          this  Debenture  or the  Shares  of  Common  Stock issuable  upon
          conversion  thereof  except  under circumstances  which  will not
          result in a violation of the Act or any applicable state Blue Sky
          or  foreign  laws  or  similar  laws  relating  to  the  sale  of
          securities.

               10.      (a)   In the event that during the period
          commencing June 1, 1997 the Market Price as previously defined
          exceeds $4.00 for five (5) trading days during any ten (10) day
          period, the Company may, upon three (3) day written notice, elect
          to convert the Debentures into Shares of Common Stock at an
          Exercise Rate computed in accordance with the provisions of 
          pargraph 4 hereof, as of the date of such notice.

                    (b)  In the event that there shall not be available any
          shares to effect the conversions of this Debenture, the Company
          shall immediately notify all Holders as listed in the Debenture
          Register. If upon conversion of this Debenture a sufficient
          amount of Common Stock is not available to satisfy all
          conversions in full, the Company shall use the available Common
          Stock to satisfy the conversions in part and the balance of the
          Debentures sought to be converted shall be redeemed for an amount
          equal to the sum of (x) 133% of the principal sum of such
          unconverted Debentures, and (y) all accrued interest, provided,
                                                                --------
          however, that nothing contained herein shall be deemed to require
          -------
          the payment of interest, at a rate in excess of the maximum rate
          permitted by applicable law.

               11.  The following shall constitute an "Event of Default":

                    a.   The Company shall default in the payment of
                         principal or interest on this Debenture for in
                         excess of ten (10) days after the due date; or

                    b.   Any of the representations or warranties made by
                         the Company herein, in the Subscription Agreement,
                         or in any certificate or financial or other
                         written statements heretofore or hereafter
                         furnished by or on behalf of the Company in
                         connection with the execution and delivery of this
                         Debenture or the Subscription Agreement shall be
                         false or misleading in any material respect at the
                         time made; or

                    c.   The Company shall fail to perform or observe, in
                         any material respect, any other covenant, term,
                         provision, condition, agreement or obligation of
                         the Company under this Debenture and such failure
                         shall continue uncured for a period of thirty (30)
                         days after notice from the Holder of such failure;
                         or

                    d.   The Company shall (1)  admit in writing its
                         inability to pay its debts generally as they
                         mature; (2) make an assignment for the benefit of
                         creditors or commence proceedings for its
                         dissolution; or (3) apply for or consent to the
                         appointment of a trustee, liquidator or receiver
                         for its or for a substantial part of its property
                         or business; or

                    e.   A trustee, liquidator or receiver shall be
                         appointed for the Company or for a substantial
                         part of its property or business without its
                         consent and shall not be discharged within ninety
                         (90) days after such appointment; or

                    f.   Any governmental agency or any court of competent
                         jurisdiction at the instance of any governmental
                         agency shall assume custody or control of the
                         whole or any substantial portion of the properties
                         or assets of the Company and shall not be
                         dismissed within ninety (90) days thereafter; or

                    g.   Any money judgment, writ or warrant of attachment,
                         or similar process in excess of Two Hundred
                         Thousand ($200,000) Dollars in the aggregate shall
                         be entered or filed against the Company or any of
                         its properties or other assets and shall remain
                         unpaid, unvacated, unbonded or unstayed for a
                         period of sixty(60) days or in any event later
                         than five (5) days prior to the date of any
                         proposed sale thereunder; or

                    h.   Bankruptcy, reorganization, insolvency or
                         liquidation proceedings or other proceedings for
                         relief under any bankruptcy law or any law for the
                         relief of debtors shall be instituted by or
                         against the Company and, if instituted against the
                         Company, shall not be dismissed within ninety (90)
                         days after such institution or the Company shall

                         acquiesce in any such proceedings or admit the

          Then, or at any time thereafter, and in each and every such case,
          unless such Event of Default shall have been waived in writing by
          the Holder (which waiver shall not be deemed to be a waiver of
          any subsequent default) at the option of the Holder and in the
          Holder's sole discretion, the Holder may consider this Debenture
          immediately due and payable, without presentment, demand, protest
          or notice of any kinds, all of which are hereby expressly waived,

          rights or remedies afforded by law.

               12.  Nothing contained in this Debenture shall be construed
          as conferring upon the Holder the right to vote or to receive
          dividends or to consent or receive notice as a shareholder in
          respect of any meeting of shareholders or any rights whatsoever
          as a shareholder of the Company, unless and to the extent 
          converted in accordance with the terms hereof.

               13.  This Debenture shall be governed and construed in
          accordance with the laws of the State of New York.

                        (ii)  PURCHASER is outside the United States as of
                              the date of the execution and delivery of
                              this Agreement.

                       (iii)  PURCHASER is purchasing the Debentures for
                              its own account and not on behalf of any U.S.
                              Person, and PURCHASER is the sole beneficial
                              owner of the Debentures, and has not pre-
                              arranged any sale with any purchaser or
                              purchasers in the United States.

                        (iv)  PURCHASER represents and warrants and hereby
                              agrees that all offers and sales of the
                              Debentures prior to the expiration of a
                              period commencing on the date of the receipt
                              of funds by the COMPANY and ending 40 days
                              thereafter (the "Restricted Period") shall
                              only be made in compliance with the safe
                              harbor contained in Regulation S, pursuant to
                              the registration provisions under the 1933
                              Act or pursuant to an exemption from
                              registration, and all offers and sales after
                              the expiration of the 40-day period shall be
                              made only pursuant to such registration or to
                              an exemption from registration.

                         (v)  PURCHASER acknowledges that the purchase of
                              the Debentures involves a high degree of
                              risk, is aware of the risks and further
                              acknowledges that it can bear the economic
                              risk of the purchase of the Debentures,
                              including the total loss of its investment.

                        (vi)  PURCHASER understands that the Debentures are
                              being offered and sold to it in reliance on
                              specific exemptions from the registration
                              requirements of U.S. securities laws and that
                              the COMPANY is relying upon the truth and
                              accuracy of the representations, warranties,
                              agreements, acknowledgements and
                              understandings of PURCHASER set forth herein
                              in order to determine the applicability of
                              such exemptions and the suitability of
                              PURCHASER to acquire the Debentures, and the
                              Shares issuable upon conversion thereof. 
                              PURCHASER represents and warrants that the
                              information contained herein is complete and
                              accurate.  PURCHASER further represents and
                              warrants that it will notify the COMPANY
                              immediately upon the occurrence of any
                              material change therein occurring prior to
                              the issuance of Shares upon conversion of the
                              Debenture.

                       (vii)  PURCHASER is sufficiently experienced in
                              financial and business matters to be capable
                              of evaluating the merits and risks of its
                              investments, and to make an informed decision
                              relating thereto.

                      (viii)  In evaluating its investment, PURCHASER has
                              consulted its own investment and/or legal
                              and/or tax advisors.  PURCHASER is not
                              relying on the COMPANY respecting the tax and
                              other economic considerations of an
                              investment in the Debentures.   

                        (ix)  PURCHASER understands that in the view of the
                              SEC the statutory basis for the exemption
                              claimed for this transaction would not be
                              present if the offering of Debentures, and
                              the Shares issuable  upon conversion thereof,
                              although in technical compliance with
                              Regulation S, is part of a plan or scheme to
                              evade the registration provisions of the 1933
                              Act.  PURCHASER is acquiring the Debentures
                              for investment purposes and has no present
                              intention to sell the Debentures, or the
                              Shares issuable upon conversion thereof, in
                              the United States or to a U.S. Person or for
                              the account or benefit of a U.S. Person
                              either now or after the expiration of the
                              Restricted Period.  

                         (x)  PURCHASER is not an underwriter of, or dealer
                              in, the Securities, and PURCHASER is not
                              participating, pursuant to a contractual
                              agreement, in the distribution of the
                              Securities.

                        (xi)  Neither PURCHASER or any of its affiliates
                              presently have or will, directly or
                              indirectly, maintain any short position in
                              securities of the COMPANY during the
                              Restricted Period.

                       (xii)  During the period  commencing on the Closing
                              Date (as defined herein) and ending on the
                              45th day following such date, PURCHASER will
                              not sell, commit or agree to sell or pledge
                              any shares of Common Stock of the COMPANY or
                              any other securities convertible into or
                              exercisable for shares of Common Stock of the
                              COMPANY.

                      (xiii)  PURCHASER has taken no action which would
                              give rise to any claim by any person for
                              brokerage commission, finders' fees or the
                              like relating to this Agreement or the
                              transactions contemplated hereby. 

                    b.   CURRENT PUBLIC INFORMATION.  PURCHASER
                         acknowledges that PURCHASER has been furnished
                         with or has acquired copies of the COMPANY's most
                         recent Annual Report on the Form 10-K filed with
                         the SEC, Forms 10-Q and 8-K filed thereafter
                         (collectively the "SEC Filings").  PURCHASER is
                         not relying upon any representations or other
                         information (whether oral or written) other than
                         as set forth in the SEC filings or in Annex IV.

                    c.   INDEPENDENT INVESTIGATION; ACCESS.  PURCHASER
                         acknowledges that PURCHASER, in making the
                         decision to purchase the Debentures subscribed
                         for, has relied upon independent investigations
                         made by it and its representatives, if any, and
                         PURCHASER and such representatives, if any, have,
                         prior to any sale to it, been given access and the
                         opportunity to examine all material publicly
                         available, books and records of the COMPANY, all

                         and to receive answers from the COMPANY or any
                         person acting on its behalf concerning the terms
                         and conditions of this offering.  PURCHASER and
                         its advisors, if any, have been furnished with
                         access to all publicly available materials

                         have received complete and satisfactory answers to
                         any such inquiries.

                    d.   NO GOVERNMENT RECOMMENDATION OR APPROVAL. 
                         PURCHASER understands that no federal or state
                         agency has passed on or made any recommendation or
                         endorsement of the Securities.

                    e.   ENTITY PURCHASERS.  If PURCHASER is a partnership,
                         corporation or trust, the person executing this
                         Agreement on its behalf represents and warrants
                         that:

                         (i)  He or she has made due inquiry to determine
                              the truthfulness of the representations and
                              warranties made pursuant to this Agreement.

                         (ii) He or she is duly authorized (if the
                              undersigned is a trust, by the trust
                              agreement) to make this investment and to
                              enter into and execute this Agreement on
                              behalf of such entity.

                    f.   Individual Purchasers.  PURCHASER, if an
                         individual, represents that he or she has reached
                         the age of 21 and has adequate means for providing
                         for his or her current and anticipated financial
                         needs and possible contingencies for emergencies
                         and has no need for liquidity in the proposed
                         investment.

                    g.   Binding Commitment.  This Agreement constitutes a
                         legal, valid and binding obligation of the
                         PURCHASER.  The PURCHASER has full power, right
                         and authority to enter into and perform this
                         Agreement.  The execution and delivery and
                         performance of this Agreement will not violate or
                         be in conflict with any order, judgment,
                         injunction, agreement or controlling document to
                         which the PURCHASER is a party or by which it is
                         bound.  If the PURCHASER is an entity, it was not
                         formed for the specific purpose of acquiring the
                         Debenture.

                    h.   Compliance.  PURCHASER hereby covenants that it
                         will comply with all laws and regulations in each
                         foreign jurisdiction in which it purchases,
                         offers, sells or deliver the Securities, or has in
                         its possession or distributes any offering
                         material.  PURCHASER undertakes and agrees to make
                         all necessary filings in connection with the
                         purchase of the Debentures as required by United
                         States laws and regulations or any domestic
                         securities exchange or trading market.

               3.   COMPANY REPRESENTATIONS.

                    a.   REPORTING COMPANY STATUS.  The COMPANY is a

                         Agreement and the issuance of the Debentures have
                         been duly and validly authorized by all necessary

                         against it in accordance with its terms, except as
                         enforceability may be limited by general equitable

                         conveyance, reorganization, moratorium or other

                    f.   NON-CONTRAVENTION.  The execution and delivery of
                         this Agreement and the consummation of the
                         issuance of the Debentures, and the consummation
                         of the transactions contemplated by this Agreement
                         by the COMPANY do not and will not conflict with
                         or result in a breach by the COMPANY of any of the
                         terms or provisions of, or constitute a default
                         under, the Certificate of Incorporation or by-laws
                         of the COMPANY, or any material indenture,
                         mortgage, deed of trust, or other material
                         agreement or instrument to which the COMPANY is a
                         party or by which it or any of its properties or
                         assets are bound or (assuming that the
                         representations and warranties of the PURCHASER in
                         Section 2 hereof, and the representations and
                         warranties of the distributor to the COMPANY, are
                         true and correct), any existing applicable U.S.
                         law, rule, or regulation or any applicable
                         decrees, judgment or order of any U.S. court,
                         federal or state regulatory body, administrative
                         agency or other U.S. governmental body having
                         jurisdiction over the COMPANY or any of its
                         properties or assets, the conflict, breach,
                         violation or default of or under which would have
                         a material adverse effect on the COMPANY's
                         business or financial condition.

                    g.   FILINGS.  The COMPANY undertakes and agrees to
                         make all necessary filings in connection with the
                         sale of the Debentures as required by United
                         States laws and regulations or any domestic
                         securities exchange or trading market.

                    h.   ABSENCE OF CERTAIN CHANGES.  Since December 31,
                         1995, there has been no material adverse
                         development in the assets, liabilities, business,
                         properties, operations, financial condition or
                         results of operations of the COMPANY, except as
                         disclosed in the SEC Filings or in Annex IV.

               4.   TRANSFER AGENT INSTRUCTIONS.  

                    a.   Debentures.  Upon the conversion of the
                         Debentures, the PURCHASER thereof shall submit
                         such Debenture to COMPANY, and COMPANY shall,
                         within five (5) business days of receipt of such
                         Debenture, instruct COMPANY's transfer agent to
                         issue one or more certificates representing that
                         number of shares of Common Stock into which the
                         Debenture or Debentures are convertible in
                         accordance with the provisions regarding
                         conversion set forth in ANNEX I hereto.  The
                         COMPANY shall act as Debenture Registrar and shall
                         maintain an appropriate ledger containing the
                         necessary information with respect to each
                         Debenture.

                    b.   Subject to the completeness and accuracy of the
                         PURCHASER's representations and warranties herein,
                         upon the conversion of any Debenture by a person
                         who is a non-U.S. Person, COMPANY shall instruct
                         the COMPANY's  transfer agent to issue stock
                         certificates without restrictive legend in the
                         name of PURCHASER (or its nominee (being a non-
                         U.S. Person) or such non-U.S. Persons as may be
                         designated by PURCHASER) and in such denominations
                         to be specified at conversion representing the
                         number of shares of Common Stock issuable upon
                         such conversion, as applicable; provided, however,
                         that if the nominee or other non-U.S. Person in
                         whose name a certificate or certificates for
                         shares are requested to be registered is other
                         than PURCHASER, or if there has been a regulatory
                         development including, but not limited to, an
                         amendment or proposed amendment of Regulation S,
                         or any "no-action" or interpretive guidance
                         whether oral or written from the Securities and
                         Exchange Commission, which call into question the
                         ability of COMPANY to issue to PURCHASER the
                         Securities without registration under the United
                         States Securities Act of 1933, COMPANY may require
                         prior to issuance of a certificate in the name of
                         PURCHASER or such other person, that it receive
                         reasonable transfer documentation including
                         opinions of counsel acceptable to COMPANY that the
                         issuance of certificates without restrictive
                         legend and/or in such other name does not and will
                         not cause a violation of the Act or any applicable
                         state or foreign securities laws.  The COMPANY
                         warrants that no instructions other than these
                         instructions and instructions to impose a "stop
                         transfer" instruction with respect to the
                         Debenture until the end of the Restricted Period
                         have been or will be given to the transfer agent
                         and that the Shares will not be subject to any
                         transfer limitations other than those imposed by
                         applicable securities laws.  Nothing in this
                         Section 4, however, shall affect in any way
                         PURCHASER's or such nominee's obligations and
                         agreement to comply with all applicable securities
                         laws upon resale of the Securities.

                    c.   If upon conversion of the Debentures effected by
                         the PURCHASER pursuant to the terms of this
                         Agreement and the Form of Debenture following the
                         expiration of the Restricted Period, the COMPANY
                         fails to issue certificates for Shares issuable
                         upon such conversion to the PURCHASER bearing no
                         restrictive legend for any reason other than the
                         COMPANY's reasonable good faith belief that the
                         representations and warranties made by the
                         PURCHASER in this Agreement were untrue when made,
                         the COMPANY shall pay to the PURCHASER by wire
                         transfer, as liquidated damages for such failure
                         and not as a penalty, an amount in cash equal to
                         $50,000; provided, however, that the payment of
                         such liquidated damages shall not relieve the
                         COMPANY from its obligations to register the
                         Shares pursuant to Section 9.

               5.   EXEMPTION; RELIANCE ON REPRESENTATION.  PURCHASER
          understands that the 
          offer and sale of the Debentures, and the Shares issuable upon
          conversion thereof, is not being registered under the 1933 Act. 
          The COMPANY is relying on the rules governing offers and sales
          made outside the United States pursuant to Regulation S.  Rules
          901 through 904 of Regulation S govern this transaction.

               6.   CLOSING DATE AND ESCROW AGENT.  The date of the
          issuance of the Debentures and the sale of the Debentures as
          evidenced by receipt by the COMPANY from the Escrow Agent or the
          total purchase funds (the "Closing Date") shall be no later than
          ten (10) business days after execution hereof by all parties or
          such other mutually agreed to time.  Debentures will be delivered
          to the Escrow Agent at the instructions of the COMPANY. 
          PURCHASER agrees that the Escrow Agent has no liability as a
          result of any fraudulent or unlawful conduct of any other party,
          and agrees to hold the Escrow Agent harmless.

               7.   CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL. 
          PURCHASER understands that COMPANY's obligation to sell the
          Debentures is conditioned upon:

                    a.   Acceptance by PURCHASER of an Agreement for the
                         sale of Debentures;

                    b.   Delivery to the Escrow Agent by each PURCHASER of
                         good funds as payment in full for the purchase of
                         the Debentures; and

                    c.   The accuracy on the Closing Date of the
                         representations and warranties of PURCHASER
                         contained in this Agreement and the performance by
                         PURCHASER on or before the Closing Date of all
                         covenants and agreements of PURCHASER required to
                         be performed on or before the Closing Date.

                    d.   There shall not be in effect any law, rule or
                         regulation prohibiting or restricting the
                         transactions contemplated hereby, or requiring any
                         consent or approval which shall not have been
                         obtained.

                8.  CONDITIONS TO PURCHASER'S OBLIGATION TO PURCHASE.  The
          COMPANY understands that PURCHASER's obligation to purchase the
          Debentures is conditioned upon:

                    a.   The receipt and acceptance by the COMPANY of this
                         Agreement as evidenced by execution of this
                         Agreement by the Chairman of the Board, President
                         or any Vice President of the COMPANY.  The
                         acceptance of funds by the COMPANY shall be deemed
                         to be constructive acceptance of this Agreement; 

                    b.   Delivery of Debentures to Escrow Agent as herein
                         set forth;

                    c.   The accuracy on the Closing Date of the
                         representations and warranties of the COMPANY
                         contained in this Agreement and the performance by
                         the COMPANY on or before the Closing Date of all
                         covenants and agreements of the COMPANY required
                         to be performed on or before the Closing Date; and

                    d.   Delivery to the Escrow Agent of an opinion of
                         counsel for the COMPANY, dated the Closing Date
                         and addressed to PURCHASER, in the form attached
                         hereto as ANNEX III.

               9.   REGISTRATION OF THE SECURITIES.  COMPANY hereby agrees
          that, upon demand of a majority in interest of holders of the
          Securities as a result of a regulatory development including, but
          not limited to, an amendment or proposed amendment of Regulation
          S, or any "no-action" or interpretive guidance whether oral or
          written from the Securities and Exchange Commission, which call
          into question the ability of PURCHASER to resell the Securities
          without registration, COMPANY will file, and use its reasonable
          best efforts to cause to become effective a registration
          statement on Form S-3 under the 1933  Act covering the resale of
          the Shares issuable upon conversion of the Debentures.  Any such
          registration statement shall remain effective for up to twelve
          (12) months, or until all of the Securities are sold, whichever
          is earlier.  The COMPANY shall provide the PURCHASER with such
          number of copies of the prospectus as shall be reasonably
          requested to facilitate the sale of the Shares issuable upon
          conversion of the Debentures.  The COMPANY shall bear and pay all
          expenses incurred in connection with any such registration,
          excluding discounts and commissions.

               10.  FURTHER OFFERINGS.  COMPANY agrees that, for a period
          of 180 days from the Closing Date, it will not offer for sale or
          sell any securities other than the Shares issuable upon
          conversion of the Debentures issued to the PURCHASER and to other
          purchasers contemporaneously herewith, unless, in the opinion of
          COMPANY's counsel, such offer or sale does not jeopardize the
          availability of exemptions from the registration and
          qualification requirements under all applicable securities laws
          with respect to the Shares.  COMPANY hereby warrants that it has
          not engaged in any such offering during the six months prior to
          the Closing Date, except as disclosed in ANNEX V hereof.

               11.  GOVERNING LAW.  This Agreement shall be governed by and
          construed under the laws of the State of New York without giving
          effect to principles governing the conflicts of laws.  A
          facsimile transmission of this signed Agreement shall be legal
          and binding on all parties hereto.

               12.  NOTICES.  Any notice required or permitted hereunder
          shall be given in writing (unless otherwise specified herein) and
          shall be deemed effectively given upon personal delivery or three
          business days after deposit in the United States Postal Service,
          by registered or certified mail with postage and fees prepaid,

                                                           Exhibit 99


              ADVANCED MAMMOGRAPHY SYSTEMS, INC. ANNOUNCED IT HAS ISSUED
             $3 MILLION IN CONVERTIBLE DEBENTURES IN A PRIVATE PLACEMENT;
                     IT WILL REMAIN AN INDEPENDENT PUBLIC COMPANY

                    Wilmington, MA, May 16, 1996 --- Advanced Mammography
          Systems, Inc. (NASDAQ: MAMO) announced it has completed a private
          placement of $3,000,000 principal amount of 4% Convertible
          Debentures due December 1, 1998.  The placement was exempt from
          the registration requirements of the Securities Act of 1933, as
          amended, pursuant to Regulation S promulgated thereunder.  The
          securities issued by the Company in the placement were not
          registered or exempted from registration requirements.

                    Advanced Mammography also announced its Board of
          Directors, given the completion of the financing, has terminated
          a previously-announced Agreement and Plan of Merger with Advanced
          NMR Systems, Inc.

                    The net proceeds of the financing will be used to
          accelerate the completion of product development for the
          company's dedicated MR Breast Imaging system and to fund a
          worldwide product launch of the system which received FDA
          clearance on February 26, 1996.

                    Jack Nelson, Chairman and Chief Executive Officer of
          Advanced Mammography Systems and Advanced NMR Systems commented: 
          "This financing will enable AMS to accomplish several objectives
          which, we believe, will accelerate the acceptance of our "Aurora"
          system in clinical markets, including: rapid deployment of a
          biopsy guidance capability and other options that will maximize
          the capabilities designed into our system, collection and
          dissemination of clinical data to demonstrate its efficacy and an
          appropriate dedication of marketing resources to accomplish
          market penetration worldwide."

                    This release contains forward-looking statements 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 product
          development, lack of market acceptance of the technology and
          changes in health care regulations, including reimbursement
          programs.

                    Advanced Mammography Systems, Inc., a majority-owned
          subsidiary of Advanced NMR Systems, Inc. (NASDAQ: ANMR), had
          developed the only dedicated Breast Imaging system based on
          magnetic resonance imaging technology.  The Company received U.S.
          Food and Drug Administration (FDA) clearance to begin commercial
          marketing activities for the product in February 1996.
