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

1.   Definitions.  The terms  listed  below  shall have the  meanings  set forth
     herein:

     a)   1998  Notes:  1998  Marciano  Note  and  1998  Muraca  Note.

     b)   2000  Notes:  2000  Marciano  Note  and  2000  Muraca  Note.

     c)   Marciano  Notes:  1998 Marciano Note and 2000 Marciano Note.

     d)   Muraca  Notes:  1998  Muraca  Note  and  2000  Muraca  Note.

     e)   Notes:  1998 Marciano Note,  1998 Muraca Note,  2000 Marciano Note and
          2000 Muraca Note.

     f)   Outstanding  Installment Payments:  When used with respect to any Note
          or Notes,  the  remaining  quarterly  installment  payments to be made
          thereunder as of December 20, 2001.

     g)   Total  Obligation:  When used with  respect to any Note or Notes,  One
          Hundred  and  Fifteen  Percent  (115%)  of the sum of the  Outstanding
          Installment  Payments  of  said  Note or  Notes  plus  the  Additional
          Interest on the 1998 Notes.  The Total  Obligation as so determined is
          $3,613,325.50 .

2.   Payment in Shares of Common Stock. Muraca and Marcinao shall accept payment
     of the Notes in shares of the Common Stock of Fonar (the "Fonar Shares") in
     consideration   of  Fonar  paying  the  full  amount  of  the   Outstanding
     Installment Payments plus the Additional Interest plus a premium of fifteen
     percent of the Outstanding Installment Payments and the Additional Interest
     (the "Total  Obligation").  Subject to the  limitations  and conditions set
     forth in this  Agreement,  the  number of Fonar  Shares to be issued in the
     aggregate  under this Agreement  shall be such number as shall be necessary
     for Muraca and Marciano to realize "Net Proceeds" of the sale thereof equal
     to the Total  Obligation  under the Notes.  "Net  Proceeds" for the purpose
     hereof  shall  mean the  proceeds  from the sale of the  shares  after  the
     deduction of all commissions and other costs of the transaction.

3.   Issuance of Shares.  No later than January 14,  2002,  Fonar shall issue to
     each of Muraca and Marciano the lesser of 1,000,000 Fonar Shares (2,000,000
     Fonar  Shares in the  aggregate)  or the  number of Fonar  Shares  having a
     market value (as hereinafter  computed) as of the day prior to the issuance
     of the Fonar Shares equal to the Total  Obligation  on the Notes payable to
     him. If on July 1, 2002, and the first day of every quarter thereafter, the
     sum of the Net  Proceeds  from the Fonar  Shares  sold by each of Muraca or
     Marciano shall not have been equal to or greater that the Total  Obligation
     on the Notes  payable  to him,  then Fonar  shall  issue to him a number of
     Fonar Shares having a market value as of the day prior to issuance equal to
     the Total  Obligation on the Notes payable to him, less the Net Proceeds of
     the Fonar Shares previously sold by him, less the market value of the Fonar
     Shares  previously issued but unsold as of the day prior to the issuance of
     the  additional  Fonar  Shares.  Fonar  shall  have the  option of  issuing
     additional  shares at such time or any time  thereafter to cover  estimated
     commissions  and other  costs of sale or to take  account of any decline in
     the market price of Fonar's Common Stock. Fonar shall retain the option not
     to issue more than 2,500,000 Fonar Shares to each of Muraca and Marciano in
     the aggregate under this Agreement, but such limitation is extended only to
     allow Fonar to limit dilution of its  outstanding  stock and will not limit
     Fonar's  liability for any portion of the Total  Obligation of the Notes in
     the event the Net Proceeds from the sale of Fonar Shares is not  sufficient
     to satisfy the Total Obligations, as contemplated in Section 10 hereof.

4.   Market  Value.  The  market  value of Fonar  Shares as of any date shall be
     determined  by taking the average of the closing  prices  (bid  prices,  if
     prices are reported only as bid and ask prices) of Fonar's  Common Stock as
     reported  on  the  NASDAQ  System  for  the  30  trading  days  immediately
     proceeding the issue date of the shares.

5.   Registration of Fonar Shares. The initial Fonar Shares which will be issued
     to Muraca and Marciano will not be registered  under the  Securities Act of
     1933, as amended (the "Securities Act"), and as such will not be able to be
     resold until they are so registered or an exemption from such  registration
     is available.  By January 15, 2002, Fonar will file with the Securities and
     Exchange  Commission  a  registration   statement  or  an  amendment  to  a
     previously  filed  registration  statement  to cover the Fonar Shares which
     have been issued and which may be issued  hereafter to Muraca and Marciano.
     Fonar will use its best  efforts  to cause the  registration  statement  to
     become effective in as short a time period as possible.  Fonar Shares which
     may be issued  following  the  original  issuance  of Fonar  Shares will be
     registered or unregistered, depending on whether the registration statement
     covering said shares has become effective.

6.   Escrow.  All Fonar  shares to be issued to Muraca and  Maricano  under this
     Agreement  will beheld in escrow by a brokerage firm selected by Muraca and
     Marciano  and  acceptable  to Fonar.  The  shares in escrow  may be sold in
     accordance  with the  instructions  of Muraca and Marciano,  subject to the
     volume  limitations  set forth in Section 7 hereof.  The  escrow  agreement
     shall be  substantially  in the form of Exhibit A hereto.  If the brokerage
     firm does not consent to act as escrow agent, the shares may be held by the
     brokerage firm as a depository  subject to the direction of an escrow agent
     mutually  agreeable to HMCA, Muraca and Marciano,  pursuant to a depository
     agreement  substantially  in the form of Exhibit B hereto.  The requirement
     that Fonar Shares be held in escrow shall not be effective until the shares
     are registered  under the Securities Act and the  restrictive  legends have
     been removed from the certificates representing the shares.

7.   Volume Limitations.  Until June 30, 2002, each of Muraca and Marciano shall
     sell not more than 66,666 shares of the Fonar Common Stock received by them
     hereunder per month,  if the average  closing bid price of the Common Stock
     of Fonar for the prior  calendar  month is at least  $1.50 per share and no
     more than 52,083 shares per month,  if the average closing bid price of the
     Common Stock of Fonar for the prior  calendar  month is less than $1.50 per
     share. In addition, at all times, both before and after June 30, 2002, each
     of Muraca and Marciano, shall sell no more than the lesser of 10,000 shares
     of Fonar Common  Stock,  or 10% of the  preceding  business  day's  trading
     volume for Fonar Common Stock, on any day. These volume  limitations may be
     increased from time to time on the mutual  agreement of the parties,  which
     need not be in writing.

8.   Suspension of Note Payments and Accrual of Interest. During the period this
     Agreement  is in  effect,  Fonar  shall not be  required  to pay any of the
     originally  scheduled  installments  of principal  and  interest  under the
     Notes.  In   consideration   of  Fonar's   agreement  to  pay  the  premium
     incorporated  into the calculation of the Total Obligation on the Notes, no
     interest  will accrue on the Notes during the term of this  Agreement,  and
     upon payment in full of the Total  Obligation  of a Note said Note shall be
     fully satisfied and paid.

9.   Obligation to Use Best Efforts to Sell.  Subject to the volume  limitations
     in Section 7 of this  Agreement,  each of Muraca and Marciano shall use his
     best efforts to sell all the Fonar Shares  issued to him. If either  Muraca
     or Marciano shall have failed to sell all of his Fonar Shares within thirty
     (30)  days of the  time he could  have,  taking  into  account  the  volume
     limitations  contained herein,  then for the purpose of determining whether
     the Total Obligation  payable on the Notes payable to him has been paid, he
     shall be deemed to have  received Net  Proceeds  equal to the higher of the
     market value of said unsold Fonar Shares as of the date they were issued to
     him or the date they first could have been sold, as determined  pursuant to
     Section 4 hereof.  The foregoing will not apply in any case where Fonar has
     consented to Muraca and  Marciano  delaying  the sale of Fonar  Shares,  or
     where Fonar has requested them to delay selling Fonar Shares.

10.  Final Payment on the Notes;  Application  of Net Proceeds;  Termination  of
     Stock Payments.  In determining  whether the Total  Obligation on the Notes
     has been  satisfied,  the Net  Proceeds  realized  by  Muraca  and shall be
     applied  pro rata to the  Muraca  Notes and the Net  Proceeds  realized  by
     Marciano shall be applied pro rata to the Marciano Notes.

If the Total Obligation with respect to a Note is not paid by the time the final
payment on said Note under the  original  payment  schedule  would have been due
(December  20, 2002 in the case of the 1998 Notes and  September 20, 2002 in the
case of the  2000  Notes),  then  interest  at the  rate of 6% per  annum  shall
commence to accrue on the unpaid  balance of the Total  Obligation  of said Note
and be included as part of the Total  Obligation.  In such case the payee on the
Note shall have the option of continuing to receive payments in Fonar Shares, in
accordance with Sections 2 and 3 of this Agreement,  until the Total  Obligation
of the Note is fully satisfied,  or to terminate the stock payments and elect to
receive the balance of the Total  Obligation  of the Note in cash or by check or
wire  transfer.  The payee may exercise this option by giving notice at any time
commencing  thirty (30) days prior to the date final payment is due by giving at
least thirty (30) days prior written notice.

10A. Other Events Giving Rise to Termination  Option.  Muraca and Marciano shall
     also have the option to terminate the payments in Fonar Shares and elect to
     receive  the  balance  of the Total  Obligation  of the Notes in cash or by
     check or wire transfer in the event any one or more of the following  shall
     occur:

     a)   Trading  of  shares of the  common  stock of Fonar  shall  cease or be
          suspended for at least five consecutive trading days; or

     b)   Fonar  shall  cease  doing  business  as  a  going  concern,  make  an
          assignment for the benefit of creditors,  file a petition commencing a
          voluntary case under any chapter of Title 11 of the United States Code
          (the "Bankruptcy Code"), be adjudicated an insolvent,  file a petition
          seeking  for  itself  any  reorganization,  arrangement,  composition,
          readjustment,  liquidation,  dissolution or similar  arrangement under
          any present or future  statute,  law,  rule or  regulation  or file an
          answer admitting the material  allegations of a petition filed against
          it in any such proceeding, consent to the filing of such a petition or
          acquiesce in the  appointment of a trustee,  receiver or liquidator of
          it or of all or any  part of its  assets  or  properties,  or take any
          action looking to its dissolution or liquidation; or

     c)   An order for relief  against  Fonar shall have been entered  under any
          chapter of the Bankruptcy  Code or a decree or order by a court having
          jurisdiction  in the  premises  shall have been  entered  approving as
          properly  filed  a  petition  seeking   reorganization,   arrangement,
          readjustment, liquidation, dissolution or similar relief against Fonar
          under any present or future statute,  law, rule or regulation,  or any
          trustee,  receiver or liquidator of Fonar or of all or any part of its
          assets and  properties  shall be  appointed;  or if there is commenced
          against  Fonar  any   proceeding   seeking  any  such  relief  or  the
          appointment of any such trustee,  receiver or liquidator which remains
          undismissed for a period of sixty (60) days.

11.  Effect of  Termination of Stock  Payments.  In the event that either Muraca
     (or his assignees) or Marciano (or his  assignees)  elects to terminate the
     payments in Fonar  Shares prior to December 20, 2002 and receive the unpaid
     portion  of the  Total  Obligation  of a Note in cash or by  check  or wire
     transfer,  then the  provisions of the  Amendment to Employment  Agreements
     executed by Muraca, Marciano, Damadian MRI in Forest Hills, P.C. and others
     concurrently  herewith  shall  terminate.  HMCA  shall have sixty (60) days
     thereafter to make full payment.

12.  Reservation of Rights Under Notes and Other  Agreements.  In the event of a
     default  under  this  Agreement  in the  payment  of any part of the  Total
     Obligation  of any Note,  then Muraca or Marciano,  as the case may be, may
     elect to  exercise  his  rights  under the Note with  respect to any amount
     which  remains  unpaid  thereunder  in  addition  to  exercising  any other
     remedies he may have under this  Agreement  or at law.  Muraca and Marciano

     shall not be deemed to be the agent of either party hereto,  or to have any
     legal or  beneficial  interest in any of the escrowed  assets.  The parties
     agree that the  Escrow  Agent  shall not be liable for any act or  omission
     taken or suffered in good faith with respect to this Agreement, unless such

          protected  and incur no  liability  relative to any action or inaction

          Escrow  Agent  shall  have  no  responsibility   for  determining  the
          genuineness or validity of any certificate,  document, notice or other

          given to it by the parties hereto in accordance  with the terms hereof
          and reasonably believed by the Escrow Agent to have been signed by the
          proper representatives of such parties.

     (c)  The Escrow Agent shall not be required to institute legal  proceedings
          of any kind.  The Escrow  Agent  shall not be  required  to defend any
          legal proceedings  which may be instituted  against it with respect to
          this  Agreement  unless  requested  to do so in  writing by any of the
          parties  hereto,  and  unless  and  until  it is  indemnified  by  the
          requesting  party to the satisfaction of the Escrow Agent, in its sole
          discretion,  against the cost and expense of such  defense,  including
          without  limitation  the  reasonable  fees and  expenses  of its legal
          counsel.  If any  conflicting  demand  shall be made  upon the  Escrow
          Agent,  it shall not be  required  to  determine  the same or take any
          action  thereon  and  may  await  settlement  of  the  controversy  by
          appropriate and nonappealable legal proceedings. Upon the commencement
          of any action  against or  otherwise  involving  the Escrow Agent with
          respect to this Agreement,  or upon advice of counsel under subsection
          (b)  hereunder,  the Escrow Agent shall be entitled to interplead  the
          matter of this escrow into a court of  competent  jurisdiction  in the
          State of New York  and,  in such  event,  the  Escrow  Agent  shall be
          relieved  of  and  discharged   from  any  and  all   obligations  and
          liabilities under this Agreement. In any such action, the Escrow Agent
          shall be entitled to the indemnities provided in Section 8 below.

8.   Indemnification  of Escrow Agent.  Fonar, HMCA, Muraca and Marciano jointly
     and severally  shall hold  harmless and  indemnify  the Escrow  Agent,  its
     partners,   employees   and  agents  from  and  against  all   obligations,
     liabilities,  claims, suits, judgments,  losses, damages, costs or expenses
     of any kind or nature,  including without limitation  reasonable attorneys'
     fees,  which may be imposed on, incurred by, or asserted against the Escrow
     Agent,  under or by reason of this Agreement,  except when due to the gross
     negligence  or  willful  misconduct  of the  Escrow  Agent.  The  foregoing
     indemnities  shall  survive  the  resignation  of the  Escrow  Agent or the
     termination of this Agreement.

9.   Resignation  of Escrow Agent.  The Escrow Agent in its sole  discretion may
     resign at any time and be  discharged  of its  duties  hereunder  by giving
     ninety (90) days prior written notice to the parties  hereto,  which notice
     shall specify the date of such  resignation.  In the event the parties fail
     to appoint a successor  escrow agent and notify the Escrow Agent in writing
     of such  appointment  within such ninety (90) day period,  the Escrow Agent
     shall be deemed to be solely a custodian of the escrowed  property  without
     further  duties  hereunder,  and shall be  entitled  to petition a court of
     competent  jurisdiction  to  appoint a  successor  escrow  agent.  Upon the
     appointment of a successor escrow agent by the parties hereunder or by such
     court, the Escrow Agent's duties and liabilities under this Agreement shall
     terminate.

10.  Assignment.  Except to the extent  provided  herein,  no  assignment by any
     party hereunder of its rights  hereunder  shall be effective  without prior
     written  consent of the other  parties  hereto,  except  that HMCA shall be
     entitled to assign its rights to its parent,  Fonar  Corporation  or to any
     successor to HMCA or Fonar  Corporation  which  agrees to be bound  hereby.
     Notice  of any  permitted  assignment  shall  be given  in  writing  by the
     assigning party to the other parties hereto.  On any permitted  assignment,
     the assignee or assignees shall be vested with all the rights,  powers, and
     remedies of the  assigning  party  hereunder.  From and after the effective
     date of any such assignment,  the Escrow Agent shall be entitled to rely on
     any  written  instructions  received  from any such  assignee,  to the same
     extent as it  previously  was entitled to rely on any written  instructions
     received from the assignor.

     of New York and shall be governed by and construed in  accordance  with the
     law of the State of New York.  Whenever  possible,  each  provision of this

     provisions of this Agreement.

only party from whom the Depository shall accept any  instructions  with respect
to the sale, assignment,  transfer, release or other disposition or treatment of
the Fonar Common  Stock and any  dividends  or  distributions  which may be paid
thereon.  The initial employees of the Escrow Agent who shall issue instructions

in the authorization.  Such authorization  shall be subject to and in accordance

hereunder only if such new  appointment or change is made in a writing signed by
Fonar, HMCA, Muraca and Marciano.

     6.  Instructions  from Fonar,  HMCA,  Muraca and Marciano.  Notwithstanding
anything  contained herein to the contrary,  if Fonar, HMCA, Muraca and Marciano

     7. Limitation of Depository's Duties.

     (a) All  parties  hereto  acknowledge  that the  duties  of the  Depository
hereunder  are solely  ministerial  in nature and have been  requested for their
convenience.  The  Depository  shall  not be deemed to be the agent of any party
hereto,  or to have any  legal or  beneficial  interest  in any of the  escrowed
assets. The parties agree that the Depository shall not be liable for any act or
omission taken or suffered in good faith with respect to this Agreement,  unless
such act or omission is the result of the gross negligence or willful misconduct
of the Depository.

     (b) The  Depository  may  consult  with  legal  counsel  and shall be fully
protected  and incur no  liability  relative to any action or inaction  taken in
good faith in accordance with the advice of such counsel.  The Depository  shall
have no  responsibility  for  determining  the  genuineness  or  validity of any
certificate,  document,  notice  or other  instrument  or item  presented  to or
deposited with it, and shall be fully protected in acting in accordance with any
written  instruction  given to it by the parties  hereto in accordance  with the
terms hereof and  reasonably  believed by the  Depository to have been signed by
the proper representatives of such parties.

     (c) The Depository shall not be required to institute legal  proceedings of
any kind. The Depository  shall not be required to defend any legal  proceedings
which  may be  instituted  against  it with  respect  to this  Agreement  unless
requested to do so in writing by any of the parties hereto, and unless and until
it is indemnified by the requesting party to the satisfaction of the Depository,
in its sole discretion,  against the cost and expense of such defense, including
without limitation the reasonable fees and expenses of its legal counsel. If any
conflicting  demand shall be made upon the Depository,  it shall not be required
to determine the same or take any action thereon and may await settlement of the
controversy  by  appropriate  and  nonappealable  legal  proceedings.  Upon  the
commencement  of any action against or otherwise  involving the Depository  with
respect to this  Agreement,  or upon  advice of  counsel  under  subsection  (b)
hereunder,  the  Depository  shall be entitled to interplead  the matter of this
escrow into a court of competent  jurisdiction  in the State of New York and, in
such event,  the Depository shall be relieved of and discharged from any and all
obligations  and  liabilities  under this  Agreement.  In any such  action,  the
Depository shall be entitled to the indemnities provided in Section 8 below.

     8. Indemnification of Depository.  Fonar, HMCA, Muraca and Marciano jointly
and severally  shall hold harmless and indemnify the  Depository,  its partners,
employees  and agents  from and against all  obligations,  liabilities,  claims,
suits,  judgments,  losses,  damages,  costs or  expenses of any kind or nature,
including without  limitation  reasonable  attorneys' fees, which may be imposed
on, incurred by, or asserted against the Depository,  under or by reason of this
Agreement,  except when due to the gross negligence or willful misconduct of the
Depository.  The  foregoing  indemnities  shall survive the  resignation  of the
Depository or the termination of this Agreement.

     9.  Resignation  of Depository.  The Depository in its sole  discretion may
resign at any time and be  discharged  of its duties  hereunder by giving ninety
(90) days prior written notice to the parties hereto, which notice shall specify
the date of such  resignation.  In the  event  the  parties  fail to  appoint  a
successor  depository and notify the  Depository in writing of such  appointment
within such ninety (90) day period,  the Depository shall be deemed to be solely
a custodian without further duties hereunder,  and shall be entitled to petition
a court of competent  jurisdiction to appoint a successor  depository.  Upon the
appointment of a successor depository by the parties hereunder or by such court,
the Depository's duties and liabilities under this Agreement shall terminate.

     10. Assignment.  Except to the extent provided herein, no assignment by any
party hereunder of its rights hereunder shall be effective without prior written
consent of the other  parties  hereto,  except  that HMCA shall be  entitled  to
assign its rights to its parent,  Fonar  Corporation or to any successor to HMCA
or Fonar  Corporation  which  agrees  to be  bound  hereby.  Notice  of any such
permitted  assignment  shall be given in writing by the  assigning  party to the
other parties  hereto.  On any permitted  assignment,  the assignee or assignees
shall be vested with all the rights, powers, and remedies of the assigning party
hereunder.  From  and  after  the  effective  date of any such  assignment,  the
Depository shall be entitled to rely on any written  instructions  received from
any such  assignee,  to the same extent as it previously was entitled to rely on
any written instructions received from the assignor.

     11.  Applicable  Law. This Agreement has been executed and delivered in the
State of New York and shall be governed by and construed in accordance  with the
law of the  State  of New  York.  Whenever  possible,  each  provision  of  this
Agreement  shall be  interpreted  in such a manner as to be effective  and valid
under  applicable  law, but, if any provision of this Agreement shall be held to
be  prohibited  or  invalid  under  applicable  law,  such  provisions  shall be
ineffective  only to the  extent  of such  prohibition  or  invalidity,  without
invalidating  the remainder of such  provisions  or the remaining  provisions of
this Agreement.

     12. Notices. Any notices or other communications  required or desired to be
