be unable to reinstate a Dissolved  Corporation  within  eighteen  months of the
Closing,  HMCA shall be under no further  obligation to do so and such Dissolved
Corporation  shall not be included as part of the  transactions  contemplated by
this Agreement.  Neither HMCA,  Damadian MRI nor RVD shall have any liability to
the Buyers in such case for failure to  reinstate  and  transfer  the  Dissolved
Corporation  and the Buyers will not have the right to offset any amounts due by
them hereunder or to any damages.

such  allocations  as they shall  agree upon  relating  to  salaries,  benefits,
insurance,  utilities  and the like (the  "Allocation  Schedule")  and make such
payments as shall be necessary in accordance therewith.

     8.  Representations and Warranties by HCMA. HMCA represents and warrants to
the Buyers as follows,  provided however,  that in making such  representations,
HMCA  is  relying  upon  the  truth  and  accuracy  of the  representations  and
warranties of the Buyers contained in the Original Stock Purchase Agreement, and
that to the  extent any  representation  or  warranty  made by HMCA is untrue or
inaccurate  with respect to any state of facts,  condition,  action or omission,
existing at or arising  prior to March 20, 1998 which was not  disclosed  by the
Buyers  in the  Original  Stock  Purchase  Agreement,  it shall  not be deemed a
misrepresentation by HMCA. Except for the representations and warranties of HMCA

Corporations by RVD shall be "AS-IS" without any representations or warranties.

duly  organized,  validly  existing and in good  standing  under the laws of the
State of New York, and has all requisite  power and authority to enter into this
Agreement and to carry out the  transactions  contemplated  hereby.  Each of the
Dissolved  Corporations  was duly  organized  under the laws of the State of New
York but was  dissolved  for failure to file returns and remit  payments for New
York  franchise  taxes.  Neither  HMCA nor RVD has sold,  assigned,  pledged  or
otherwise transferred or encumbered any of the shares of A&A or the Professional
Corporations  they  acquired from the Buyers or caused  additional  shares to be
issued.  Neither HMCA nor RVD is a party to or bound by any commitment,  plan or
arrangement  to issue or sell any capital stock or any other equity  interest in
A&A or a Professional Corporation and there are no outstanding options, warrants
or other  commitments  or obligations  exercisable or convertible  into any such
security or interest in A&A or a Professional Corporation, except the obligation
to transfer and pledge the shares of the Dissolved  Corporations as set forth in
this Agreement.  Neither A&A nor any Professional  Corporation is required to be
qualified  licensed or  domesticated  as a foreign  corporation  in any State or
other  jurisdiction on the basis of its properties owned or business  transacted
as of the date hereof. (b) Authorization,  Et Cetera. The execution and delivery
of this Agreement and the sale and all other  transactions  contemplated  hereby
have been duly authorized by HMCA,  Damadian MRI and RVD. No consent,  approval,
authorization  or  order  of,  or  registration,   qualification,   designation,
declaration  or filing  with,  any  governmental  authority on the part of HMCA,
Damadian MRI or RVD is required in connection with the execution and delivery of
this Agreement or the carrying out of any transactions  contemplated hereby. (c)
Subsidiaries.  Neither A&A nor any  Professional  Corporation  owns any stock or
other equity interest in any corporation, limited liability company, partnership
or other entity.

     (ii) an income  statement for A&A showing the revenues and expenses by each
of the sites and expenses which cannot be allocated by site. Also included is an

eight month period ended February 28, 2003.

     (iii) a schedule  of  accounts  payable as at April 7, 2003 for A&A.  As of
said date there was no accounts payable for the Professional Corporations or any
other  known   indebtedness   and  obligations  of  A&A  and  the   Professional
Corporations except as disclosed in this Agreement.

     All financial  statements and schedules,  referred to above are, or will be
when  delivered,  complete  and  correct in all  material  respects  prepared in
accordance with generally accepted accounting  principles  consistently  applied
throughout the periods  indicated,  fairly present or will when delivered fairly
present,  in all  material  respects,  the  financial  position  of A&A  and the
Professional  Corporations  as at the dates  indicated  and the results of their
operations for the periods indicated, and disclose all known liabilities,  as at
said dates,  except to the extent those  liabilities are disclosed  elsewhere in
this Agreement or a schedule or exhibit hereto.

     (e) Absence of Certain  Changes.  Since  February 28,  2003,  there has not
been:

     (i) any changes in the business, condition (financial or otherwise), assets
or liabilities of A&A or any Professional Corporation, whether or not covered by
insurance and whether or not arising from transactions in the ordinary course of
business, which, individually or in the aggregate, have been materially adverse,
except that revenues and patient billings have materially  declined and expenses
have become past due because of insufficient revenues. In addition, the landlord
for the premises located at 86-18 Jamaica Avenue has sent a letter,  dated March
7, 2003,  claiming  certain  breaches of the terms of the lease.  Except for the
obligation  to pay  monthly  rent which may be due prior to the date of Closing,
HMCA shall have no obligation to take any action to cure or otherwise  deal with
the alleged breaches. A copy of this letter has been provided to the Buyers.

     (ii) any damage, destruction or other casualty loss (whether or not covered
by insurance)  materially  and adversely  affecting the business or prospects of
any of A&A or the Professional  Corporations or any of the assets and properties
of A&A or the Professional Corporations; and

     (iii)  the  operations  and  business  of each of A&A and the  Professional
Corporations  has been conducted in all respects only in the ordinary course and
substantially  in the manner in which they have been  conducted  since they were
acquired  by HMCA & RVD,  except  that  the  Dissolved  Corporations  have  been
inactive.

     (f) Tax  Returns and  Payments.  All tax returns and reports of each of A&A
and the  Professional  Corporations  required by law to be filed for all periods
from March 20, 1998 up to the Closing Date have been duly filed,  and all taxes,
assessments,  fees and other governmental  charges upon any properties,  assets,
income or franchises of A&A or any Professional  Corporation or for which any of
them is otherwise  liable,  which are due and payable for all periods from March
20,  1998 up to the Closing  Date have been paid except for (a) Corona,  Liberty
and  Ridgewood,  which have been inactive and have not filed any returns or paid
taxes,  including  franchise taxes (b) tax returns have not been filed and taxes
have not been paid for  Physicians  for 2001 and 2002 (2002 is on extension) and
(c) taxes which are presently payable without penalty or interest.  The charges,
accruals and reserves on the books of A&A and the Professional Corporations with
respect to taxes for all fiscal  periods are  adequate and HMCA does not know of
any actual or  proposed  tax  assessment  for any fiscal  period or of any basis
therefor  other than as so  reflected  on their  respective  books and  records,
except for such taxes, interest and penalties which may be due for the Dissolved

any  extensions  thereof for real property  which are in their  possession or of

them harmless from and against any rents not paid prior to the Closing, with the

by A&A or Physicians except as set forth Exhibit L hereto. A&A or Physicians has
good and marketable title to each of said items of personal property and assets,
in each case subject to no mortgage,  pledge, lien,  conditional sale agreement,
encumbrance or charge, except as set forth in Exhibit L attached hereto. None of
said personal  properties or assets is held by A&A or Physicians as lessee under
or subject to any lease or as conditional  vendee under any conditional  sale or
other title retention agreement, except as set forth in Exhibit L. All inventory

received any notice or other communication, whether formal or informal, from any
supplier of gas, oil or electric power or of supplies or other materials used in
its business or operations to the effect that any such energy  source,  supplies
or  material  will  become  unavailable  to an extent  which  might  impair  the
continued conduct of its business or operations at their current levels.

     (k)  Insurance.  All property and  operations  of A&A and the  Professional
Corporations are adequately insured with responsible  insurers against all risks
normally  insured  against by  companies in similar  lines of business.  Each of
these insurance policies is fully paid for periods extending in all cases beyond
the Closing Date,  but will be  terminated  by HMCA  effective as of the Closing
except as may be otherwise agreed upon by HMCA and the Buyers at the Closing and
appropriately  referenced  in the  Allocation  Schedule to be agreed upon at the
Closing. A schedule of such insurance is set forth in Exhibit P.

     (l) Disclosure.  Neither this Agreement nor any certificate,  list or other
instrument  purporting to disclose facts germane to the businesses of A&A or the
Professional  Corporations  delivered  or to be delivered to the Buyers by or on
behalf  of  HMCA  pursuant  hereto  or  in  connection  with  the   transactions
contemplated  hereby contains or will contain any untrue statement of a material
fact.  To the best of HMCA's  knowledge,  there is no fact  directly  related to
A&A's and Physicians'  businesses  known to HMCA which  materially and adversely
affects the business, properties,  operations, condition or prospects, financial
or otherwise, of A&A and the Professional  Corporations,  which has not been set
forth in this Agreement or in the other  documents,  certificates and statements
already  furnished to the Buyers by or on behalf of HMCA in connection  with the
transactions contemplated hereby.

     (m) Contracts. With the exception of those contracts and commitments listed
or referred to in Exhibit M, neither A&A nor any  Professional  Corporation is a
party to or bound by any written contract or commitment, other than:

     (i) orders and commitments for the purchase of supplies or services entered
into in the ordinary  course of  business,  other than those which may have been
made by or at the direction of the Buyers and the responsibility for which shall
be as reflected in the Accounts Payable Schedule or Allocation Schedule.

     (ii)  requests  for medical  services or medical or  diagnostic  procedures
scheduled  by  patients  or  referring  physicians,  independently  of any other
agreement or contract.

     (iii) maintenance, service and other contracts for A&A and the Professional
Corporation's  equipment,  made in the  ordinary  course of business  other than
those  which may have been made by or at the  direction  of the  Buyers  and the
responsibility  for which shall be as reflected in the Accounts Payable Schedule
or the Allocation Schedule; or

     (iv)  employment   relationships  not  under  written  agreement  with  the

this Agreement or an Exhibit hereto,  to the best of HMCA's  knowledge,  A&A and
the  Professional  Corporations  are in  full  compliance  with  all  applicable
statutes, regulations, decrees, orders, restrictions,  guidelines and standards,
imposed by the United  States of America,  any state,  county,  municipality  or
agency of any thereof,  or any other  governmental,  regulatory or  professional
authority,  except  that the  Dissolved  Corporations  have  failed  to file tax
returns or make required tax payments and to the best knowledge of HMCA, neither
A&A nor a Professional  Corporation has received any written  notification  from
the United States of America, any state,  county,  municipality or agency of any
thereof or any other governmental,  regulatory or professional authority that it
is not in such full compliance, except as aforesaid.

     (o) Employees.  Attached hereto as Exhibit N is a true and complete list of
all persons employed by A&A and the Professional Corporations,  specifying their
rates of  compensation,  benefits plans in which they  participate and time they
have taken off for sickness,  vacation and personal reasons from January 1, 2003
through March 21, 2003.  The Buyers are included on the list because even though
they are employees of Damadian  MRI,  they are actually  paid by Physicians  and
following  the Closing will not be  employees of Damadian  MRI. The salaries are
shown at their current hourly rates, except for Absar Haaris, Jodie Keating, the
Buyers,  Francesco Passarelli and Augustos Zevallos, whose salaries are shown at
their current annual rates.  The  percentages  in the 401k column  represent the
percentage  withheld  from the  employee's  salary  until the maximum  allowable
amount is  reached.  There is no  employer  contribution  to the 401k Plan.  The
columns for  Medical and Dental show which,  if any, of those plans in which the
employee participates.  The chart does not include bonuses or other benefits not
listed  (e.g.  cell  phones)  which  they  may  be  entitled  to  under  written
agreements.

     (p)  Labor  Contracts,   Et  Cetera.   Neither  A&A  nor  any  Professional
Corporation  is a party  to any  collective  bargaining  or  other  labor  union
contract  applicable to any persons employed by such corporation.  HMCA does not
know of any  activities or  proceedings  of any labor union (or  representatives
thereof) to organize any employees of A&A or any Professional Corporation, or of
any  threats  of  strikes  or  work  stoppages  by any  employees  of A&A or any
Professional Corporation.

     (q)  Litigation,  Et Cetera.  To the best of HMCA's  knowledge  there is no
litigation,  arbitration,  proceeding or  investigation  pending or  threatened,
which might, either individually or collectively, result in any material adverse
change in the  business or  condition  (financial  or  otherwise)  of A&A or any
Professional Corporation or in any of its respective properties or assets, or in
any material liability on the part of A&A or any Professional Corporation, or in
any material change in the methods of doing business of A&A or any  Professional
Corporation  except  as  set  forth  in  Exhibit  O.  There  is  no  litigation,
arbitration,  proceeding or  investigation  pending or threatened  against HMCA,
Damadian  MRI, RVD, A&A or the  Professional  Corporations  which  questions the
validity of this  Agreement or of any action taken or to be taken pursuant to or
in connection with the provisions of this Agreement.

     (r) Broker.  Neither  HMCA,  Damadian MRI nor RVD have employed any finder,
broker,  agent or other  intermediary  in  connection  with the  negotiation  or
consummation of this Agreement or any of the transactions  contemplated  hereby,
and HMCA and  Damadian  MRI will  indemnify  the Buyers  and hold them  harmless
against all liabilities,  expenses,  costs,  losses and claims,  if any, arising
from the  employment  by, or services  rendered to it (or any  allegation of any
such employment by, or services rendered to it) of any finder,  broker, agent or
other intermediary in such connection.

     (c) Compliance with Other  Instruments.  Neither the execution and delivery
of this Agreement nor the carrying out of the transactions  contemplated  hereby

decree,  order,  statute,  rule or  regulation  by which either of the Buyers is
bound. (d) Broker. Neither Buyer has employed any finder, broker, agent or other

compliance with their obligations under this Agreement,  neither HMCA,  Damadian
MRI,  their  shareholders,  affiliates  nor any other  entity  now  existing  or
hereafter  formed which any of them may own,  control or manage (the "Restricted

at any one time do not exceed one percent (1%) of the total shares of such class
outstanding  and provided  further that such party exercises no control over and
performs no executive,  management or other services for such competitor. To the
extent that the foregoing  covenant shall be held to be invalid or unenforceable
by a court  of  competent  jurisdiction,  such  court  may  impose  such  lesser
restrictions  as such court  shall deem  necessary  or  appropriate  to properly
protect A&A and the Professional Corporations,  but any such determination as to
the  invalidity  or  unenforceability  of this  covenant  shall not  affect  the

not prohibit  Physician from providing  medical  services in connection with any
charitable  activity or any research  conducted for  charitable,  educational or
other non-profit  entities  provided that the Buyer receives no compensation for
said  activities.  In addition,  nothing  contained herein shall prohibit either
Buyer from  purchasing  and holding  shares of stock of a competitor of HMCA, or

one time do not  exceed  one  percent  (1%) of the total  shares  of such  class
outstanding and provided  further that he exercises no control over and performs
no executive,  management or other services for such  competitor.  To the extent

court of  competent  jurisdiction,  each Buyer agrees that such court may impose
such lesser  restrictions  as such court shall deem  necessary or appropriate to
properly protect, HMCA, its subsidiaries,  affiliates and HMCA Managed Entities,
but any such  determination  as to the  invalidity or  unenforceability  of this
covenant shall not affect the validity or enforceability  hereof in any State or

(including  reasonable  attorneys'  fees) arising after the Closing from events,
acts or omissions,  occurring  after the Closing and to the extent  reflected in

which are  incurred  or  suffered  by, or  asserted  or claimed  against,  HMCA,
Damadian  MRI or  RVD  relating  to or  arising  out of A&A or any  Professional

                                    GUARANTY

This  Guaranty  dated as of April 8, 2003 is made and delivered by A&A Services,
Inc., Dr. Giovanni Marciano & Dr. Glenn Muraca, Physicians, P.C., Corona Medical
Offices,  P.C.,  Liberty Medical Offices,  P.C. and Ridgewood Medical Care, P.C.
(the "Corporations") to Health Management Corporation of America ("HMCA").

In consideration of HMCA entering into a certain Stock Repurchase and Settlement
Agreement   (the   "Repurchase   Agreement")   dated  April  8,  2003  with  the
Corporations,  Dr. Glenn Muraca ("Muraca"),  Dr. Giovanni Marciano ("Marciano"),
Damadian MRI in Forest  Hills,  P.C.  and Fonar  Corporation,  the  Corporations
hereby  irrevocably  and  unconditionally  guarantee  to HMCA,  the  payment and
performance  when due,  whether  at  maturity,  or earlier  by  acceleration  or
otherwise,  or later in the case of one or more extensions of time of payment or
renewal,  in whole or in part of the  Repurchase  Promissory  Note  executed  by
Muraca  and  Marciano  under  the  Repurchase  Agreement  and any and all  other
obligations  of  Muraca  and  Marciano  under   Repurchase   Agreement  and  the
agreements,  instruments and documents issued thereunder (the  "Obligations") in
accordance  with and  subject  to the terms  and  conditions  of the  Repurchase
Agreement.

The  Corporations  waive  (i)  notice  of  acceptance  of  this  Guaranty,  (ii)
presentment,  demand of payment,  protest,  notice of dishonor or non-payment of
any  Obligations  and  (iii)  any  other  notice  to  any  party  liable  on the
Obligations.

HMCA may at any time and from time to time  without  the  consent  of, or notice
(except as shall be required by applicable statute and cannot be waived) to, the
Corporations,  without incurring  responsibility  to the  Corporations,  without
impairing or releasing the obligations of the  Corporations  hereunder,  upon or
without any terms or  conditions  and in whole or in part:  (1) change or extend
the manner,  place,  terms or time of payment or otherwise alter any Obligation,
and the  Guaranty  herein  made shall  apply to the  Obligations  as so changed,
extended or altered; (2) sell,  exchange,  release,  surrender,  realize upon or
otherwise deal with in any manner and in any order any property by whomsoever at
any time pledged or mortgaged to secure the Obligations hereby  guaranteed;  (3)
exercise or refrain from  exercising  any rights  against Muraca and Marciano or
others; (4) settle or compromise any liability hereby  guaranteed,  any security
therefor  and may  subordinate  the  payment  of all or any part  thereof to the
payment of any  liability  of Muraca and  Marciano  to  creditors  of Muraca and
Marciano other than HMCA; or (5) apply any sums by whomsoever  paid or howsoever
realized to any liability or  liabilities of Muraca and Marciano on whose behalf
such payment is made to HMCA  regardless  of what  liability or  liabilities  of
Muraca and Marciano remain unpaid.

The Corporations further guarantee that all payments made by Muraca and Marciano
to HMCA on any Obligation  hereby guaranteed will, when made, be final. If claim
is ever  made upon HMCA for  repayment  or  recovery  of any  amount or  amounts
received  by HMCA in payment or on account of any of the  liabilities  of Muraca
and  Marciano,  and HMCA  repays all or part of said amount by reason of (a) any
judgment,   decree  or  order  of  any  court  or  administrative   body  having
jurisdiction,  or (b) any settlement or compromise of any such claim effected by
HMCA with any such claimant (including Muraca and Marciano),  or (c) as a result
of any order,  settlement or rule entered in or  applicable  in any  bankruptcy,
insolvency or similar  proceeding  instituted by or against Muraca and Marciano,
then and in any such event the  Corporations  agree that such judgment,  decree,
order,  settlement,  compromise or rule shall be binding upon the  Corporations,
notwithstanding  any  revocation  hereof  or the  cancellation  of any  note  or
instrument  evidencing any liability of the  Corporations,  and the Corporations
shall be and  remain  liable  to HMCA  hereunder  for the  amount  so  repaid or
recovered  to the same  extent  as if such  amount  had  never  originally  been
received by HMCA.

Any acknowledgement or new promises, whether by payment of principal or interest
or  otherwise,  and  whether by Muraca and  Marciano  or others,  including  the
Corporations,  with respect to any of the liabilities of Muraca and Marciano, if
the statute of  limitations  in favor of Muraca and Marciano  against HMCA shall
have  commenced to run,  shall toll the running of such statute of  limitations,
and, if the period of such statute of  limitations  shall have expired,  prevent
the operation of such statute of limitations.

No delay on the part of HMCA in exercising any of its options, powers or rights,
or partial or single exercise  thereof,  shall  constitute a waiver thereof.  No
waiver of any of its rights hereunder,  and no modification or amendment of this
Guaranty,  shall  be  deemed  to be made by HMCA  unless  the  same  shall be in
writing,  duly signed on behalf of HMCA,  and each such  waiver,  if any,  shall
apply only with respect to the specific instance  involved,  and shall in no way
impair the rights of HMCA or the obligations of the  Corporations to HMCA in any
other respect at any other time.  This Guaranty may not be modified orally or by
course of conduct.

The  Corporations  represent and warrant to HMCA that the  Corporations  are not
insolvent  and will not be rendered  insolvent by the  execution and delivery of
this Guaranty. The Corporations  acknowledge and confirm to HMCA that, except as
otherwise  set forth in a writing,  the  Corporations  have not been  induced to
execute and deliver this Guaranty as a result of, and are not relying upon,  any
representations,  warranties,  agreements  or  conditions,  whether  express  or
implied or written or oral, by any other  person.  HMCA shall not be required to
reserve its rights against the  Corporations  in connection with any settlement,
compromise  or  release  of any  liability  hereby  guaranteed  or any  security
therefor.  For purposes of this paragraph  "insolvent" shall mean "unable to pay
debts as they mature".

This  Guaranty  shall inure to the benefit of any assignee of HMCA of all or any
part of the Obligations.

The  Corporations  hereby consent to the  jurisdiction of any court of record of
New York State or of the United  States  District  Courts for the  Southern  and
Eastern Districts of New York over the Corporations.

This Guaranty shall be governed in accordance  with the laws of the State of New
York.

This Guaranty is a guaranty of payment and not one of  collection,  and it shall
be  binding  upon  the  Corporations   and  their  respective   representatives,
successors and assigns in favor HMCA and its successors and assigns.

This Guaranty shall not be binding upon Corona Medical  Offices,  P.C.,  Liberty
Medical  Offices,  P.C. or Ridgewood  Medical Care,  P.C. until such time as the
Corporation is reinstated and all of the issued and  outstanding  shares of said
Corporation  are  transferred  to  Muraca  and/or  Marciano  or their  permitted
assignees.

Dr.  Giovanni  Marciano & Dr. Glenn Muraca,  Physicians,  P.C.,  Corona  Medical

(hereinafter  sometimes referred to as the "Corporations") and Health Management
Corporation of America (the "Secured Party").

                                   WITNESSETH:

     WHEREAS,  all of the issued and  outstanding  stock of the  Corporations is
being sold to Dr. Glenn Muraca and Dr. Giovanni Marciano (the "Buyers") pursuant
to a Stock  Repurchase  and  Settlement  Agreement  dated  April  8,  2003  (the
"Repurchase Agreement") and in connection therewith and in partial consideration
for said  stock,  the Buyers  have  agreed to pay the  Secured  Party the sum of
$2,500,000  pursuant to a promissory note dated the date hereof (the "Repurchase
Promissory Note") pursuant to the Repurchase Agreement; and

     WHEREAS,  in order to induce the Secured Party to enter into the Repurchase
Agreement  and  to  accept  the  Repurchase  Promissory  Note  as  part  of  the
consideration  payable to the Secured Party  thereunder,  the Corporations  have
agreed to grant the  Secured  Party a security  interest in all of assets of the
Corporations,  whether owned immediately prior to the closing (the "Closing") of
the purchase and sale of the stock of the  Corporations  or thereafter  acquired
(the "Collateral") to secure the payment the Repurchase  Promissory Note and the
other  obligations  of the  Buyers  and the  Corporations  arising  under  or in
connection with the Repurchase Agreement;

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

1. Security  Interest.  To secure the payment and  performance of the Repurchase
Promissory  Note and any other  obligations  of the Buyers and the  Corporations
under the Repurchase  Agreement and any agreement,  instrument or other document
executed  pursuant  to  the  Repurchase  Agreement  (the   "Obligations"),   the
Corporations  hereby grant and assign to the Secured Party a continuing security
interest in their  respective  interests in the  Collateral.  As used herein the
term "Collateral" shall mean all of the assets of the Corporations,  whether now
owned or hereafter  acquired,  whether real,  personal,  tangible or intangible,
including, without limitation, all accounts receivable, claims, contract rights,
corporate names, intellectual property,  furniture,  fixtures, office equipment,
office supplies,  medical equipment,  medical  instruments and medical supplies,
all substitutes and accessories  thereto, the proceeds thereof and all books and
records of the Corporations.

2.  Representations,  Warranties  and  Covenants.  The  Corporations  represent,
warrant and covenant as follows:

     a.  One or more  of the  Corporations  is the  owner  of  each  item of the
Collateral, free and clear of any liens, security interests,  mortgages, pledges
or other  encumbrances  except  for  "Permitted  Encumbrances"  (as  hereinafter
defined), and the Corporations, jointly and severally, shall keep the Collateral
free and clear of any liens,  security  interests,  mortgages,  pledges or other
encumbrances other than Permitted  Encumbrances or those in favor of the Secured
Party. For the purposes hereof,  the term Permitted  Encumbrances shall mean (i)
any lien, security interest,  mortgage,  pledge or other encumbrance existing at
the time of the  Closing,  (ii) any  agreement  between any of the  Corporations
pursuant to which any of the Collateral is leased by one Corporation to another,
or the use of the Collateral is provided by one  Corporation  to another,  (iii)
liens for taxes or other governmental assessments which are not yet due or which
are being  contested in good faith by  appropriate  proceedings,  (iv) workmen's
liens,  materialmen's liens and the like which may arise by statute or operation
of law, provided that the Corporations shall pay any obligations secured thereby
when due, or contest the same by appropriate proceedings and (v) liens, security
interests, conditional sales or title retention agreements securing the purchase
price of any items of Collateral acquired after the Closing.

     b.  The  principal   executive  offices  and  places  of  business  of  the
Corporations are located and the books and records of the Corporations including
those relating to the  Collateral are located in Queens County,  New York at the
locations specified in Exhibit B to the Repurchase Agreement.

     c. The  Corporations  will not move any tangible assets included as part of
the Collateral  without the written consent of the Secured Party or any of books
and records of the  Corporations  without first  notifying the Secured Party and
executing and delivering to the Secured Party such  financing  statements as are
necessary in order to enable to Secured  Party to perfect its security  interest
hereunder at the location where any such Collateral is to be moved.

     d.  The  Corporations  will  not use the  Collateral  in  violation  of any
applicable law, ordinance or regulation.

     e. The  Corporations  will  promptly pay any taxes and  assessments  levied
against  the  Collateral,   unless   contested  in  good  faith  by  appropriate
proceedings.

     f. The  Corporations  will  execute and  deliver to the Secured  Party such
financing  statements and other  instruments  and documents as the Secured Party
may from time to time  request  which in the  opinion of the  Secured  Party are
necessary or  desirable  to confirm or to perfect the  security  interest of the
Secured Party granted hereby.

     g. Nothing contained herein shall prevent the Corporations from liquidating
any  accounts  receivable  included  in the  Collateral  and using the  proceeds
thereof or any cash on hand in the ordinary  course of business,  subject to the
provisions of the  Repurchase  Agreement  and any  agreements,  instruments  and
documents executed pursuant to the Repurchase Agreement,  as long as no Event of
Default as hereinafter described, has occurred and remains uncured.

     h.  Unless  expressly  permitted  under  the terms of this  Agreement,  the
Corporations shall not sell, assign, transfer or otherwise dispose of any of the
Collateral without the consent of the Secured Party.

     i. The  Corporations  shall  insure the  tangible  assets  included  in the
Collateral  against fire, theft and other casualty and obtain general  liability
insurance  in such  amounts and to such  extent as the Secured  Party shall from
time to time deem reasonable and appropriate.  Such  policy(ies)  shall name the
Secured Party as an additional  insured,  as its interests may appear, and shall
provide for thirty (30) days prior  written  notice to the Secured  Party of any
cancellation.  In addition, each of the professional corporations included among
the Corporations shall maintain professional malpractice insurance in amounts as
the Secured Party shall deem  reasonable and  appropriate,  which policies shall
provide for thirty (30) days prior written  notice to the Secured Party prior to
any  cancellation.  The  Corporation  shall  provide  the Secured  Parties  with
certificates  evidencing  all of the  foregoing  insurance  or  copies  of  such
insurance policies upon request.

     3. Sale or Transfer of Collateral.  A Corporation shall not assign, sell or
otherwise  transfer  or  convey  all or any part of the  Collateral  to  another
Corporation  without the consent of the Secured Party;  in the event the Secured
Party  shall  consent  to any such  transfer,  any  transferee  shall  take such
Collateral subject to the security interest of the Secured Party provided herein
and shall assume the obligations of the transferor hereunder with respect to the
Collateral  acquired by such  transferee and such  transferee  shall execute and
deliver to the Secured Party such financing statements and other instruments and
documents as the Secured  Party may require to preserve  its  security  interest
granted hereunder in such Collateral.  Nothing contained herein,  however, shall
permit the movement of any tangible  assets  included as part of the  Collateral
other than in accordance with the provisions of Section 2(c) hereof.

4. Default Under Security Agreement.  The Corporations shall be in default under
this Security  Agreement if any Corporation  shall default in the performance of
any of its  obligations  hereunder and such default is not cured within  fifteen
days of the  giving  of  written  notice  thereof  by the  Secured  Party to the
Corporation  or if any  Corporation  or either of the Buyers shall be in default
under the  Repurchase  Agreement,  the Repurchase  Promissory  Note or any other
agreement,  instrument or document executed pursuant to the Repurchase Agreement
and such  default  is not  cured  within  any  applicable  grace or cure  period
provided (any of the foregoing being  sometimes  referred to herein as an "Event
of Default")

5. Rights and Remedies.  If any Event of Default  shall occur,  then the Secured
Party shall have and may  exercise  the rights and  remedies of secured  parties
provided under the Uniform Commercial Code or under the Repurchase  Agreement or
any agreement, instrument or document executed under the Repurchase Agreement.

6. Power of Attorney.  Each of the Corporations hereby appoints HMCA as its true
and  lawful  agent and  attorney-in-fact,  with full power of  substitution,  to
execute or file any financing  statements or other  instruments  or documents in
the name of the  Corporation  as may be necessary or  appropriate  to,  perfect,

the  Collateral  hereunder  and to exercise the rights and remedies  provided or
referred to in Section 5 hereof in the name of the Corporation or in the name of
the Secured Party,  as the Secured Party shall deem  necessary or expedient,  in
its sole  discretion,  and to executed any further  instruments and documents in
connection  therewith as the Secured Party shall deem  necessary or expedient in
connection therewith,  in the name of the Corporation or the name of the Secured
Party.

with the laws of the State of New York.

          attorney granted to HMCA by Physicians pursuant to this Agreement. The
          special and limited power of attorney  granted herein shall be coupled
          with an interest and shall be irrevocable.  The irrevocable  powers of
          attorney  shall expire  following the  termination  of this  Agreement
          after all  Receivables  have been collected or written off by HMCA and
          the Receivables Account is closed.

2. THE RECEIVABLES ACCOUNT

stated herein. The Receivables  Account shall be account number  865500604165 at
Chase Manhattan Bank or such other account as may be mutually agreed upon by the

shall apply to that account).  Physicians shall ensure that Raymond V. Damadian,
or one of HMCA's officers, as designated by HMCA, shall be the sole signatory on
the Receivables Account.

3. DISBURSMENT OF RECEIVABLES

execute and deliver all further instruments and documents,  and take all further
action that may be necessary,  or that HMCA may reasonably  request, in order to
evidence or confirm the  assignment of the  Receivables  to HMCA,  the ownership
thereof by HMCA and the right of HMCA to bill for and collect the Receivables.

     Physicians  irrevocably  authorizes HMCA to notify patients and third-party
payors to make  payment  directly to HMCA of any  Receivables,  and agree that a
copy of this Agreement shall  constitute  sufficient  authorization  to any such
payors to make payment to HMCA.  Physicians  expressly  waives any right to seek

lawsuits,  judgments,  costs and expenses (including  reasonable  attorneys fees
incurred in respect of any such claims or liability) arising from any billing or
collection practices of HMCA used in connection with the Receivables ("Claims").
In the event of any Claim with respect to which an Indemnified  Party intends to
seek  indemnification  hereunder,  the Indemnified  Party shall give HMCA prompt
written notice of such Claim and HMCA shall have the right to assume the defense
of the Claim  with  counsel of its own  choosing  reasonably  acceptable  to the
Indemnified  Party  provided that such defense is conducted  with  diligence and
continuity and provided  further the  Indemnified  Party shall have the right to
participate  in the  defense of such Claim with  counsel of its  choosing at its
expense.  The  parties  shall  cooperate  in the  defense  of any such Claim and
neither HMCA nor the Indemnified Party shall have the right to settle or pay any
such  Claim  without  the  consent  of the  other,  unless  the party or parties
settling the Loss secure the release of the other parties from any liability for
the Claim.

8. RELATIONSHIP OF THE PARTIES

     The relationship of the HMCA to A&A and Physicians  hereunder shall be that
of  independent  contractors.  HMCA is not and  shall not hold  itself  out as a

                                    EXHIBIT I

                                PLEDGE AGREEMENT

     PLEDGE  AGREEMENT  dated as of April  8,  2003  between  Dr.  Glenn  Muraca
("Muraca") and Dr.  Giovanni  Marciano  ("Marciano"),  having an office at 86-16
Jamaica Avenue,  Woodhaven,  New York 11421 and Health Management Corporation of
America (the  "Secured  Party"),  a Delaware  corporation  having its  principal
office at 6 Corporate Center Drive, Melville, New York 11747.

                                   WITNESSETH:

     WHEREAS,  Muraca and  Marciano  are  indebted to the  Secured  Party in the
principal  amount  of  $2,500,000,  as  evidenced  by  a  promissory  note  (the
"Repurchase Promissory Note") dated the date hereof;

     WHEREAS,  the Repurchase  Promissory Note was executed and delivered to the
Secured Party as partial  consideration  by the Buyers under a Stock  Repurchase
and  Settlement  Agreement  dated  April 8,  2003 (the  "Repurchase  Agreement")
pursuant to which the shares of A&A Services,  Inc., Dr. Giovanni Marciano & Dr.
Glenn Muraca,  Physicians,  P.C., Corona Medical Offices,  P.C., Liberty Medical
Offices, P.C. and Ridgewood Medical Care, P.C. (the "Corporations") were sold to
Muraca and Marciano;

     WHEREAS, Muraca and Marciano are the sole stockholders of the Corporations;

     WHEREAS,  in order to induce the  Secured  Party to accept  the  Repurchase
Promissory Note and to secure the payment of the Repurchase  Promissory Note and
any  obligations  arising  thereunder  or  otherwise  by Muraca and  Marciano to
Secured Party under the Repurchase  Agreement and any  agreement,  instrument or
document   executed  and  delivered   under  the   Repurchase   Agreement   (the
"Indebtedness"),  Muraca and Marciano  have agreed to grant the Secured  Party a
security  interest in all of the shares of the issued and  outstanding  stock of
the Corporations (the "Pledged Shares").

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

1. Pledge and  Security  Interest.  To secure the  payment of the  Indebtedness,
Muraca and Marciano hereby pledge the Pledged Shares and grant and assign to the
Secured  Party a continuing  security  interest in the Pledged  Shares.  As used
herein,  the term  Pledged  Shares  shall  include  the  Pledged  Shares and the
proceeds thereof. Simultaneously herewith, Muraca and Marciano are delivering to
the Secured Party the certificates  representing the Pledged Shares,  with stock
powers duly executed in blank.  Any dividends or distributions in cash, stock or
other  property paid on the Pledged  Shares,  as well as any  different  type or
number of shares of stock into which the Pledged Shares may be changed, shall be
delivered to the Secured Party to be held hereunder to secure the payment of the
Indebtedness  and shall be included within the definition of Pledged Shares.  2.
Representations,  Warranties  and  Covenants.  Muraca and  Marciano  represents,
warrants and covenants as follows:

     a.  Muraca and  Marciano  or either of them are the  owners of the  Pledged
Shares, free and clear of any pledges,  liens, security interests,  mortgages or
other  encumbrances,  and Muraca and Marciano shall keep the Pledged Shares free
and  clear  of any  pledges,  liens,  security  interests,  mortgages  or  other
encumbrances.  The Pledged Shares  constitute all of the issued and  outstanding
shares of the Corporations.

     b. Muraca and Marciano will promptly pay any taxes and  assessments  levied
against  the  Pledged  Shares,  unless  contested  in good faith by  appropriate
proceedings.

     c. Muraca and Marciano  shall ensure that the  Corporations  will not issue
any additional shares of capital stock or other securities, warrants or options,
or enter into any agreements to do so.

     d. Muraca and Marciano shall ensure that the Corporations will not merge or
consolidate with any other entity, liquidate or dissolve, amend their respective
certificates of incorporation or declare or make any dividend or distribution of
any kind with respect to their outstanding shares of stock.

     e. Muraca and Marciano shall ensure that the Corporations  will not sell or
otherwise  transfer or dispose of any of their assets  other than in  accordance
with the applicable  provisions of any agreements  between the  Corporations and
Secured Party.

     f. Muraca and Marciano  will execute and deliver to the Secured  Party such
financing  statements and other  instruments  and documents as the Secured Party
may from time to time  request  which may be  necessary  to perfect the security
interest of the Secured Party granted hereby.

3.  Events of  Default.  The  happening  of any of the  following  events  shall
constitute an event of default hereunder ("Event of Default"): the occurrence of
an event of default or a default  under the  Repurchase  Promissory  Note or any
other  obligation  of  Muraca  and  Marciano  to the  Secured  Party  under  the
Repurchase  Agreement,  this  Stock  Pledge  Agreement  or any other  agreement,
instrument or document executed pursuant to the Repurchase Agreement.

4.  Remedies.  Upon the  occurrence of any such Event of Default and at any time
thereafter,  the  Secured  Party may,  without  notice to Muraca  and  Marciano,
declare all of the Indebtedness or any part thereof  immediately due and payable
and shall have the remedies of a secured party under the Uniform Commercial Code
or other  applicable  law.  The  Secured  Party will give  Muraca  and  Marciano
reasonable notice of the time and place of any public sale of the Pledged Shares
or of the time after which any private sale or any other intended disposition of
the Pledged  Shares is to be made.  The Secured  Party or any one or more of its
affiliates,  if legally  qualified,  may purchase the Pledged Shares at any such
public or private sale. The  requirements  of reasonable  notice shall be met if
such  notice is mailed  postage  prepaid to the  address of Muraca and  Marciano
shown at the beginning of this  Agreement at least five (5) days before the time
of sale or  disposition.  Expenses of sale shall  include  the  Secured  Party's
reasonable  attorney's fees and legal expenses.  The Secured Party may apply the
proceeds from any sale of the Pledged Shares to any Indebtedness secured thereby
in such order and such amounts as the Secured Party in its sole  discretion  may
elect.  Muraca and Marciano shall be liable for any deficiency  remaining  after
sale of the Pledged Shares and  application of the proceeds to the  Indebtedness
and to the expenses allowed hereunder and by applicable law.

5.  Alternative  Remedy.  Alternatively,  upon  the  occurrence  of an  Event of
Default,  the Secured  Party may transfer all or any part of the Pledged  Shares
into its name or the name of its assignee and  thereafter  the Secured  Party or
any such assignee may exercise all of the rights of the sole  stockholder of the
Corporations  of which it holds the  shares,  including  but not  limited to the
election and removal of directors or the sale of the assets of the Corporations.
Upon the  taking  of  control  of the  Corporations,  the  Secured  Party or its
assignee may enter upon the premises and take  possession  of and use the assets
of the  Corporations  to operate  and  conduct  the  business  conducted  by the
Corporations  on said  premises in the name of the Secured Party or its assignee
or in the name of the  Corporations,  as the Secured  Party or its  assignee may
elect.  In such case,  the net proceeds  collected  by the Secured  Party or its
assignee,  after the deduction of expenses, may be retained by the Secured Party
or its assignee and applied to any outstanding  Indebtedness.  In the event that
Secured Party shall elect to exercise the remedy  provided in this  Paragraph 5,
nothing contained herein shall obligate the Secured Party or its assignee to pay
or  perform  any debts or  obligations  of the  Corporations  to third  parties,
although the Secured Party or its assignee may elect to do so for the account of
the Corporations.  In such case, the Secured Party or its assignee shall have no
liability to the  Corporations or the  Corporations  for payment of any expenses
incurred  in  connection  with  operating  the  business  or for  payment of any
obligations  or claims  believed  by the Secured  Party or its  assignee in good
faith to be  obligations of the  Corporations.  The election by Secured Party of
the remedy  provided in this  Paragraph 5 shall not preclude  the Secured  Party
from subsequently electing to pursue other remedies provided herein or otherwise
under other agreements or by law.

6. Power of  Attorney.  To enable the Secured  Party to exercise  its rights and
remedies hereunder,  each of Muraca and Marciano hereby appoints and constitutes
the  Secured  Party,  with full  power of  substitution,  as his true and lawful
attorney  to  exercise  all rights and  privileges  with  respect to the Pledged
Shares and to receive all benefits  therefrom,  to the same extent as Muraca and
Marciano would be entitled.

     And each of Muraca and  Marciano  does  hereby  ratify and confirm all that
said  attorneys  shall  lawfully  do,  or  cause to be done,  in and  about  the
premises, by virtue hereof.

     This power of attorney is coupled with an interest and shall be irrevocable
until such time as the  Indebtedness  secured by this Stock Pledge  Agreement is
paid in full.

7. Governing Law and Jurisdiction. The Agreement shall be construed and enforced
in accordance with the laws of the State of New York. The Courts of the State of
New York for New York County and Suffolk  County and the Federal  Courts for the
Eastern and  Southern  Districts  of the State of New York shall have  exclusive
jurisdiction in any litigation relating to or arising from this Agreement.

8. Miscellaneous.  This Agreement shall be binding upon and inure to the benefit
of the parties hereto and their  respective  successors  and permitted  assigns.
This Agreement shall not be assignable by Muraca and Marciano  without the prior
written  consent of the Secured  Party.  The Secured Party may assign its rights
and benefits under this  Agreement to any assignee,  including the assignment of
its rights and interests in any Pledged Shares of a professional  corporation to
a physician  licensed under the laws of the State of New York. Any  termination,
waiver or modification  of the terms and provisions  hereof shall be in writing.
Any notice  required or permitted  hereunder shall be deemed given if in writing
and  delivered  personally  or sent by certified  or  registered  mail,  postage
prepaid,  addressed  to the party to which it is given at the  address  for such
party specified at the outset hereof.

9. Effectiveness. This Pledge Agreement shall not be applicable to the shares of
Corona Medical Offices, P.C., Liberty Medical Offices, P.C. or Ridgewood Medical
Care,  P.C.  until such time as the  corporation  is  reinstated  and all of the
issued and  outstanding  shares of said  corporation  are  transferred to Muraca
and/or Marciano or their permitted assignees.

     IN WITNESS  WHEREOF,  the parties  hereto have executed and delivered  this
Agreement  in the manner  legally  binding  upon them as of the date first above
written.
