                             ABOUT FONAR CORPORATION

     At Fonar we design, manufacture and market magnetic resonance imaging (MRI)
scanners.  MRI scanners use magnetic fields to generate images of organs,  bones
and tissue  inside the human body.  The MRI scanner uses a magnetic  field which
causes  the  hydrogen  atoms in  tissue  to align.  When the  magnetic  force is
withdrawn,  the atoms fall out of alignment  emitting  radio signals as they do.
The speed at which the atoms fall out of  alignment,  or  "relaxation  time" and
radio signals vary  depending on the type of tissue and whether any pathology is
present.  The radio signals provide the data from which the scanner's  computers
generate an image of the body part being scanned.

                                     Page 2


     Fonar offers the  following  MRI scanners:  the  Stand-Up(TM),  also called
Indomitable(TM) , QUAD(TM),  Fonar-360(TM)  and Echo(TM).  The QUAD-S(TM) MRI, a
work-in-progress, also has received FDA clearance to market.

     The  Stand-Up  allows  patients to be scanned  while  standing,  sitting or
reclining.  This means that an  abnormality  or injury,  such as a slipped disc,
will be able to be scanned under full weight-bearing  conditions, or, more often
than not, in the  position in which the patient  experiences  pain.  An elevator
built into the floor brings the patient to the desired height in the scanner. An
adjustable bed allows the patients to stand, sit or lie on their backs, sides or
stomachs,  at any angle. In the future,  the Stand-Up may also be useful for MRI
directed surgical procedures.

     The Fonar 360 is an enlarged room sized magnet in which the floor,  ceiling
and walls of the room are part of the magnet frame.  Consequently,  this scanner
allows 360 degree access to the patient.  The Fonar 360 is presently marketed as
a diagnostic scanner and is sometimes referred to as the Open Sky MRI.

     In the future,  we may also further develop the Fonar 360 to function as an
operating room. We sometimes refer to this contemplated version of the Fonar 360
as the OR-360.

     The QUAD  scanner is  supported  by four  posts and is open on four  sides,
thereby allowing access to the scanning area from four sides.

     The QUAD-S is a superconductive version of our open iron frame magnet.

     Fonar also offers a low cost, low field open MRI scanner, the Echo.

     In addition to manufacturing MRI scanning  systems,  we formed a subsidiary
in 1997, Health Management Corporation of America, which we sometimes call HMCA,
to engage in the  business  of  managing  MRI  imaging  facilities  and  medical
practices.  HMCA  provides and  supervises  the  non-medical  personnel  for the
clients at their sites. At HMCA we also provide our clients centralized billing,
collection, marketing,  advertising,  accounting and financial services. We also
provide office equipment and furnishing,  consumable  supplies and in some cases
the office space used by our clients.  Almost all of HMCA's client  professional
corporations are owned by Fonar's founder,  President and Chairman of the Board,
Dr. Raymond V. Damadian.

     HMCA  currently  manages  11  MRI  facilities,  six  physical  therapy  and
rehabilitation  practices and four primary care medical practices.  For the 2002
fiscal  year,  the  revenues  HMCA  recognized  from  the  MRI  facilities  were
$15,514,294,   the   revenues   recognized   from  the   physical   therapy  and
rehabilitation  practices were $11,493,680 and the revenues  recognized from the
primary  care medical  practices  were  $1,517,465.  For the first six months of
fiscal 2003, the revenues  recognized from the MRI facilities  were  $7,062,653,
the revenues  recognized from the physical therapy and rehabilitation  practices
were  $4,860,000  and the  revenues  recognized  from the primary  care  medical
practices were $774,805.

     Approximately  64% of our  consolidated  revenues for the fiscal year ended
June 30,  2002 and 75% for the fiscal  year ended June 30, 2001 were from HMCA's
management services.  Approximately 43% of our consolidated revenues for the six
months ended December 31, 2002 were from HMCA's management services.

     Approximately  99% of HMCA's revenues and 68% of our consolidated  revenues
for the fiscal  year ended June 30, 2002 and 98% of HMCA's  revenues  and 76% of
our  consolidated  revenues for the fiscal year ended June 30, 2001 were derived
from professional  corporations owned by Dr. Raymond V. Damadian.  Approximately
99.9% of HMCA's revenues and 53% of our consolidated revenues for the six months
ended December 31, 2002 were derived from professional corporations owned by Dr.
Raymond V. Damadian.  The  consolidated  revenues include revenues from sales by
Fonar to such professional  corporations:  $3.1 million for the first six months
of fiscal 2003, $2.5 million for fiscal 2002 and $1.1 million for fiscal 2001.

                                  RISK FACTORS

     An investment in Fonar is highly  speculative  and subject to a high degree
of risk. Therefore,  you should carefully consider the risks discussed below and
other  information  contained in this  prospectus  before  deciding to invest in
shares of our common stock.

1.   We have and continue to experience significant losses.

     For the fiscal years ended June 30, 2002 and June 30, 2001, we  experienced
net losses of $22.9  million and $15.2  million  respectively  and net operating
losses of $19.7  million  and  $16.2  million,  respectively.  For the first six
months of fiscal 2003,  ended  December 31, 2002,  we  experienced a net loss of
$5.6 million and a net operating loss of $5.4 million, as compared to a net loss
of $8.6  million  and a net  operating  loss of $7.4  million for the six months
ended  December 31, 2001.  We have been able to fund our losses to date from the
$7,125,000 in funding  received  from The Tail Wind Fund Ltd.  between May, 2001
and  August,  2002 and the $128.7  million  judgment,  net $77.2  million  after
attorney's  fees,  received  from  General  Electric  Company in 1997 for patent
infringement   and  the  settlement   proceeds  from  other  patent   litigation
settlements with other competitors. The terms of these settlement agreements are
required to be kept  confidential.  As of June 30,  2002,  however,  our balance
sheet reflected approximately $7.5 million in cash and cash equivalents and $5.6
million in marketable securities out of total current assets of $41.5 million as
compared to  approximately  $14.0 million in cash or cash  equivalents  and $6.1
million in marketable securities out of total current assets of $40.9 million as
at June 30, 2001.  As of December 31, 2002,  our balance  sheet  reflected  $4.9
million in cash and cash  equivalents and $5.7 million in marketable  securities
out of total current assets of $38.1 million. We believe that we will be able to
reverse our operating losses with the  introduction  into the marketplace of our
new MRI scanners,  particularly our  Stand-Up(TM)  MRI scanners.  HMCA operating
income has declined  however  from $2.5 million in fiscal 2000,  to $1.0 million
for fiscal 2001 and to an operating  loss of $4.3  million for fiscal 2002.

                                     Page 4


     For the first six months of fiscal 2003,  ended  December  31,  2002,  HMCA
experienced  an operating  loss of $719,000 as compared to  operating  income of
$559,000  for  the  six  months  ended  December  31,  2001.  Of  the  HMCA  and
consolidated  operating  losses for fiscal 2002,  $4.7 million was an impairment
loss taken with respect to  management  agreements  for the primary care medical
practices as a result of losses  recognized by that division of HMCA's business.
Contributing to the net loss for fiscal 2002 was an additional  non-cash expense
of $2.4 million in financing  costs  incurred in  connection  with the discounts
received on the stock issued to The Tail Wind Fund.  There can be no  assurance,
however, that we can reverse our operating losses.

2.   Fonar is dependant on the success of its new products to become profitable.

     Our ability to generate future operating profits will depend on our ability
to market and sell our new lines of MRI products.  The Stand-Up  MRI,  Fonar 360
and Echo scanners have all been recently introduced into the market. Although we
are optimistic that these scanners'  features will make them competitive,  there
can be no  assurance  as to the degree or timing of market  acceptance  of these
products.  Nevertheless,  we  received  orders for 19 Stand-Up  MRI  scanners in
fiscal 2002 and orders for 8 Stand-Up  MRI  Scanners for the first six months of
fiscal 2003.  Revenues from the sales of QUAD scanners,  introduced in 1995, had
not been sufficient to date to generate  operating  profits.  The product we now
are  currently  promoting  most  vigorously  is the Stand-Up MRI. We believe the
Stand-Up MRI is the most  promising  because it enables scans to be performed on
patients in weight bearing positions,  such as sitting,  standing or lying at an
angle.  The  market for the  Stand-Up  MRI shows  strong  initial  promise.  The
following chart shows the revenues attributable to each model during fiscal year
2001, fiscal year 2002 and the first six months of fiscal year 2003. Please note
that we recognize  the revenue on scanner  sales on a percentage  of  completion
basis. This means we book revenue not as cash is received or sales are made, but
as the scanner is built.  Consequently,  the revenues for a fiscal period do not
necessarily relate to the orders placed in that period.

                               Revenues Recognized
                               -------------------

3.   We must compete in a highly  competitive  market against  competitors  with
     greater financial resources than we have.

                                     Page 5


     The medical equipment  industry is highly  competitive and characterized by
rapidly changing  technology and extensive research and development.  The market
demand for a continuing  supply of new and improved products requires that we be
engaged  continuously  in research and  development.  New products  also require
continuous retooling or at least modifications to our manufacturing  facilities,
and our sales and marketing force must  continuously  adjust to new products and
product  features.  This is highly  expensive and companies  with  substantially
greater  financial  resources  than we have engage in the  marketing of magnetic
resonance   imaging   scanners  which  compete  with  the  Company's   scanners.
Competitors include large,  multinational  companies or their affiliates such as
General Electric Company,  Siemens A.G.,  Marconi  International,  Philips N.V.,
Toshiba  Corporation  and Hitachi  Corporation.  There can be no assurance  that
Fonar's  products  will be able to  successfully  compete  with  products of its
competitors.

4.   The  success of some of the  businesses  purchased  by HMCA  depends on the
     continued employment of the former owners of those businesses.

     The businesses acquired by HMCA are essentially service organizations whose
continued  success  depends  on  retaining  and  developing   existing  business
relationships.  These  relationships are often heavily dependent on the personal
efforts of key persons in the acquired company or medical  practices  managed by
the  acquired  company.  HMCA has retained  certain of these key people  through
employment agreements which include both noncompetition  covenants and financial
incentives.  Nevertheless,  there can be no assurance that these key people will
remain as employees or produce results sufficient to make the acquired companies
profitable.

5.   The decline in profitability of the primary care medical  practices managed
     by HMCA resulted in an impairment loss of $4.7 million in fiscal 2002.

     HMCA manages 11 MRI  facilities,  six physical  therapy and  rehabilitation
practices and four primary care medical practices.  During 2002 fiscal year, the
primary care medical  practices,  which are managed by the Company's  subsidiary
A&A Services,  Inc.  experienced a significant overall decline in patient volume
and  related  operating  cash flows  which led to the  inability  of the medical
practices  to fully and timely pay  management  fees.  The  business of managing
these  practices  had been  acquired by HMCA in fiscal 1998.  As a result of the
continued  negative  trend,  HMCA incurred an impairment loss of $4.7 million in
fiscal 2002 related to those  management  agreements  which reduced the carrying
value of such  agreements to  approximately  $3.5 million at June 30, 2002.  The
revenues  and  operating  losses for the four  primary  care  medical  practices
deteriorated  from $3.1 million and ($362,000)  respectively,  in fiscal 2001 to
$1.5 million and ($5.3)  million,  respectively,  in fiscal  2002.  Revenues and
operating losses for the four primary care practices in the six months of fiscal
2003 were $775,000 and ($222,000) respectively,  as compared to $1.0 million and
($53,000) respectively for the first six months of fiscal 2002.

6.   HMCA'S profitability depends on its ability to successfully perform billing
     and  collection  services  for  its  clients.

     HMCA performs billing and collection services for the medical practices and
MRI facilities it manages.  The viability of HMCA's clients and their ability to
remit  management fees to HMCA depends on HMCA's ability to collect the clients'
receivables.  Collectibility of these  receivables can be adversely  affected by
the  longer  payment  cycles and  rigorous  informational  requirements  of some
insurance  companies  or  other  third  party  payors.  Proper   authorizations,

                                     Page 6


referrals  and  confirmation  of  coverage  for  patients,  as well as issues of
medical  necessity,  need to be addressed  prior to the  rendering of service to
assure prompt payment of claims. HMCA believes it is properly addressing billing
and collection  requirements  and issues for its clients and that its collection
rates are good.  Nevertheless,  the regulations and  requirements  applicable to
medical billing and collections could change in the future and result in reduced
or  delayed  collections.  Approximately  99%  of  the  receivables  billed  and
collected  by HMCA are  from  professional  corporations  owned  by  Raymond  V.
Damadian.

7.   Capitated  insurance  programs  could  adversely  affect HMCA's  clients by
     shifting a part of the  financial  responsibility  for patient  care to the
     medical providers.

     Certain HMO's and insurers have instituted  managed care programs where the
physician or physician  group is paid on a capitated  basis.  Under these plans,
the  physician is not paid  according to the  services  provided,  but is paid a
fixed  monthly fee per patient,  which in HMCA's  experience is based on age and
gender.  In fiscal 2002 and fiscal 2001,  respectively,  1.9% and 2.0% of HMCA's
clients' revenues were from capitated  programs.  All of these were attributable
to primary medical care practices  managed by A&A Services,  Inc.,  representing
33% and 30% of their revenues in fiscal 2002 and fiscal 2001, respectively.  For
the first six months of fiscal 2003, 1.4% of HMCA's clients'  revenues and 14.9%
of the revenues of the primary  medical care practices  managed by A&A Services,
Inc. were from capitated  programs.  Under  capitated  insurance  programs,  the
physician or physician  practice in effect bears some of the risk in the event a
patient requires  extensive  treatment.  In the event that HMCA's client primary
care  practices  experience a shortfall  between the capitated  payments and the
cost of  providing  services,  the ability of those  practices to pay for HMCA's
services may be impaired.

8.   The profitability of HMCA could be adversely  affected if medical insurance
     reimbursement rates change.

     HMCA receives  substantially  all of its revenue from medical practices and
providers of MRI services.  Consequently,  HMCA would be indirectly  affected by
changes in medical  insurance  reimbursement  policies,  HMO policies,  referral
patterns,  no-fault  and  workers  compensation  reimbursement  levels and other
factors affecting the  profitability of a medical practice or MRI facility.  The
types of medical  providers  served by HMCA are (a) MRI facilities,  (b) primary
care practices and (c) physical therapy and rehabilitation practices.  There are
11 MRI facilities served by HMCA located in New York,  Florida and Georgia.  The
primary  care  practices  served by HMCA consist of four offices in New York and
the physical therapy and rehabilitation practices consist of six offices located
in New York.  Approximately  52% of HMCA's  clients'  revenues in fiscal 2002 as
compared to  approximately  56% of HMCA's clients'  revenues in fiscal 2001 were
generated from the no-fault and personal injury protection claims. For the first
six months of fiscal 2003,  approximately  58% of HMCA's  clients  revenues were
generated from the no-fault and personal injury protection  claims.  Although we
do not  know  of any  pending  adverse  development  affecting  these  types  of
facilities,  future changes in the  reimbursement  levels for MRI, primary care,
workers  compensation  or no fault  reimbursement,  or  changes  in  utilization
policies for MRI or physical  rehabilitation  therapy could adversely affect the
ability of HMCA's  clients to pay HMCA's fees. In addition,  HMCA depends on the
ability of the medical  practices and providers to attract and retain physicians
and other professional staff.

                                     Page 7


9.   The  amortization  of the  management  agreements on our balance sheet will
     reduce future profits.

     HMCA acquired  businesses  which were  essentially  service  businesses for
purchase prices based on earnings  multiples rather than net tangible assets. As
the fair value of the tangible  assets was small relative to the purchase price,
the  consolidated  balance  sheet  of Fonar  and its  subsidiaries  reflects  an
allocation  of the  purchase  price in excess of the fair value of the  tangible
assets  exclusively  to management  agreements,  an intangible  asset with a net
carrying value of approximately $20.4 million at June 30, 2001, $14.5 million as
at June 30, 2002 and $14.0 million as at December 31, 2002.  The initial  amount
allocated  to  management  agreements  attributable  to  the  acquisitions,  was
approximately  $24.4  million.  Prior  to the  write  down of the  value  of the
management  agreements for the primary care medical practices of $4.7 million in
fiscal 2002,  amortization of management  agreements,  which is over a period of
twenty (20) years,  reduced net profits by approximately  $1.2 million annually.
This is a non-cash  expense.  It is expected that the amortization of management
agreements  after  the  write-down  for the  impairment  loss  will be  $983,700
annually.

10.  Professional  liability  claims  against  HMCA or its  clients  may  exceed
     insurance coverage levels.

     Although  HMCA does not provide  medical  services,  it is possible  that a
patient suing one of HMCA's client  medical  practices or MRI  facilities  would
also sue HMCA.  With the  exception  of one MRI  facility,  neither HMCA nor its
clients carry professional  liability  insurance.  Physicians working for HMCA's
clients  or  for  HMCA's   subsidiaries,   however,  are  required  to  maintain
professional liability insurance in the minimum amount of $1,000,000/$3,000,000.
Such  insurance  would  not  cover  HMCA or a client  professional  corporation,
however, in the event a claim were made which was not covered by the physician's
insurance.  Claims  in  excess  of  insurance  coverage  might  also  have to be
satisfied by HMCA or its clients if they were named as defendants.

11.  We do not carry  product  liability  insurance  and  would  have to pay any
     claims from our revenues and capital resources.

     Fonar  does not carry  product  liability  insurance  but is  self-insured.
Consequently,  Fonar would have to pay from its own resources any valid products
liability claim. To date, Fonar has not had to pay any such claims.

12.  We are dependent upon the services of Dr. Damadian.

     Our success is greatly  dependent upon the continued  participation  of Dr.
Raymond V. Damadian,  Fonar's founder,  Chairman of the Board and President. Dr.
Damadian  has acted as our CEO  since  1978 and will  continue  to do so for the
foreseeable  future. In addition to providing general supervision and direction,
he provides active direction, supervision and management of our sales, marketing
and research and  development  efforts.  In  connection  with the  physician and
diagnostic  management  services  business  conducted by HMCA, Dr. Damadian owns
most of the professional corporations which are HMCA clients. With the exception
of four  professional  corporations  which provided  management  fees to HMCA of

                                     Page 8


approximately  $422,500  in the  aggregate  for  fiscal  2002 and  approximately
$108,000 in the  aggregate  for the first six months of fiscal 2003,  all of the
professional corporations are owned by Dr. Damadian. Loss of the services of Dr.
Damadian would have a material adverse effect on our business. We do not have an
employment or  noncompetition  agreement with Dr. Damadian.  We do not currently
carry "key man" life insurance on Dr. Damadian.

13.  Dr. Raymond V. Damadian has voting control of Fonar; the management  cannot
     be changed or the company sold without his agreement.

     Dr. Raymond V. Damadian, the President, Chairman of the Board and principal
stockholder  of Fonar is and will  continue  to be in  control of Fonar and in a
position to elect all of the directors of Fonar. As of February 10, 2003,  there
were outstanding  76,680,706 shares of common stock,  having one vote per share,
4,153 shares of Class B common  stock,  having ten votes per share and 9,562,824
shares of Class C common stock,  having 25 votes per share.  Of these totals Dr.
Damadian owns 2,488,274  shares of common stock and 9,561,174  shares of Class C
common stock,  giving him over 75% of the voting power of Fonar's  voting stock.
This  means that the  holders  of the  common  stock will not be able to control
decisions  concerning any merger or sale of Fonar,  the election of directors or
the determination of business and management policy.

14.  The provisions of our warrants provide for reductions in the exercise price
     if we issue  common  stock at prices  below  market  or below  the  warrant
     exercise prices.

     In connection with the issuance of 4% convertible  debentures issued to The
Tail Wind Fund Ltd, we issued warrants. Presently, there are outstanding:

     -    purchase  warrants to purchase an aggregate  of 959,501  shares of our
          common  stock at an  exercise  price of $1.801 per  share,  subject to
          adjustment; and

     -    callable  warrants to purchase an aggregate of 2,000,000 shares of our
          common stock at a fluctuating exercise price which will vary depending
          on the market price for our common stock.

     Of the purchase  warrants,  659,501 were issued to The Tail Wind Fund, Ltd.
and  300,000  were  issued to  designees  of the  placement  agent,  Roan/Meyers
Associates,  L.P. None of the purchase  warrants have been  exercised and all of
the  purchase  warrants  are still  outstanding.  The  exercise  period  for the
purchase warrants extends to May 24, 2006.

     The callable  warrants  cover  2,000,000  shares of common stock and have a
variable  exercise  price.  Subject to a maximum  price of $6.00 per share and a
minimum price of $2.00 per share, which is subject to adjustment pursuant to the
terms of the warrants, the exercise price is to be calculated to be equal to the
average  closing bid price of Fonar's  common stock for the full calendar  month
preceding the date of exercise.  The callable warrants will be exercisable until
August 30, 2005.  These  callable  warrants  were issued to replace the original
callable warrants, which were exercised in full.

                                     Page 9


     We do have  the  option,  however,  of  redeeming  up to  200,000  callable
warrants  per month at a price of $0.01 per  underlying  warrant  share,  if the
average  closing bid price of Fonar's  common  stock is greater than 115% of the
warrant price in effect for five consecutive trading days in any calendar month.
We also have the  option of  reducing  the  exercise  price  under the  callable
warrants to any lower exercise  price that was  previously in effect.  .........
Both the  purchase  warrants  and callable  warrants  provide for  proportionate
adjustments  in the event of stock  splits,  stock  dividends  and reverse stock
splits. In addition, the exercise prices will be reduced, with certain specified
exceptions,  if we issue shares at lower prices than the warrant exercise prices
or the then current market price for our common stock.

                           FORWARD-LOOKING STATEMENTS

     We make  statements in this  prospectus and the documents  incorporated  by
reference that are considered  forward-looking  statements within the meaning of
the Securities Act of 1933 and the Securities  Exchange Act of 1934. The Private
Securities  Litigation  Reform Act of 1995  contains the safe harbor  provisions
that cover these forward-looking statements. We are including this statement for
purposes  of  complying  with  these  safe  harbor  provisions.  We  base  these
forward-looking  statements on our current  expectations  and projections  about
future  events.  These  forward-looking  statements are not guarantees of future
performance and are subject to risks,  uncertainties and assumptions  including,
among other things:

     continued losses and cash flow deficits;

     the continued availability of financing in the amounts, at the times and on
     the terms required to support our future business;

     uncertain market acceptance of our products; and

     reliance on key personnel.

     Words  such  as  "expect,"   "anticipate,"   "intend,"  "plan,"  "believe,"
"estimate" and variations of such words and similar  expressions are intended to
identify such forward-looking statements. We undertake no obligation to publicly
update or revise  any  forward-looking  statements,  whether  as a result of new
information,  future events or otherwise.  Because of these risks, uncertainties

                                USE OF PROCEEEDS

     We cannot  guarantee  that we will receive any proceeds in connection  with
this offering.  We intend to use the net proceeds of this offering,  if any, for
general  corporate  purposes,   including  working  capital  to  fund  operating
expenses, accounts payable and capital expenditures. Accordingly, our management
will have broad  discretion  in the  application  of any net proceeds  received.
Pending  such uses,  we intend to invest  the net  proceeds,  if any,  from this
offering in short-term, interest-bearing, investment grade securities.

                              PLAN OF DISTRIBUTION

     We may sell the shares being offered by us in this prospectus:

     -    through dealers, brokers or agents;

     -    through underwriters;

     -    directly  to  purchasers;  or  through a  combination  of any of these
          methods of sale.

     -    We and our agents and  underwriters  may sell the shares being offered
          by  us  in  this   prospectus  from  time  to  time  in  one  or  more
          transactions:

     -    at market prices prevailing at the time of sale;

     -    at prices related to such prevailing market prices;

     -    at a fixed price or prices, which may be changed; or

     -    at negotiated prices.

     In addition to any underwriters we may use, any brokers,  dealers or agents
who  participate  in  the  distribution  of  the  shares  may  be  deemed  to be
underwriters,  and any profits on the sale of shares by them and any  discounts,
commissions  or  concessions  received by any  broker,  dealer or agent might be
deemed to be underwriting discounts and commissions under the Securities Act. In
any such case, any such  underwriters  may be subject to statutory  liabilities,
including,  but not limited to, Sections 11, 12 and 17 of the Securities Act and
Rule 10b-5 under the Securities Exchange Act. These provisions of the securities
laws provide,  in general  terms,  for liability  for fraud,  untrue  statements
contained  in a  prospectus  or otherwise  made in  connection  with the sale of
securities,  and the  failure  to  disclose  significant  information  which  is
necessary to prevent information disclosed from being misleading.

     We may solicit  directly offers to purchase  shares.  We may also designate
agents from time to time to solicit offers to purchase shares. Any agent that we
designate,  may then resell  such  shares to the public at varying  prices to be
determined by such agent at the time of resale.

     We may engage in at the market  offerings of our common  stock.  An "at the
market"  offering is an offering of our common stock at other than a fixed price
to or through a market maker.  Under Rule 415(a)(4) of the  Securities  Act, the
total value of at the market offerings made under this prospectus may not exceed
10% of the aggregate market value of our common stock held by non-affiliates.

     If we use  underwriters to sell shares,  we will enter into an underwriting
agreement  with the  underwriters  at the time of the sale to them. The names of
the  underwriters  will be set forth in the prospectus  supplement which will be
used by them  together  with this  prospectus to make sales of the shares to the
public. Details of our arrangement with the underwriter,  including commissions,
underwriting  discounts or fees paid by us and whether the underwriter is acting
as  principal  or  agent,  would  be  described  in the  prospectus  supplement.
Underwriters may also receive commissions from purchasers of the shares.

                                    Page 11


     Underwriters may use dealers to sell shares.  If this happens,  the dealers
may receive  compensation  in the form of discounts,  concessions or commissions
from the underwriters  and/or  commissions from the purchasers for whom they may
act as agents.

     Any  underwriters  to whom we sell shares for public  offering and sale may
make a market in the shares that they purchase, but the underwriters will not be
obligated  to do so and may  discontinue  any market  making at any time without
notice. Underwriters and agents also may engage in transactions with, or perform
services for, us in the ordinary course of business.

     Regardless of the method used to sell the common  stock,  we will provide a
prospectus supplement that will disclose:

     -    the identity of any  underwriters,  dealers or agents who purchase the
          common stock;

     -    the material terms of the distribution, including the number of shares
          sold and the consideration paid;

     -    the  amount  of  any  compensation,  discounts  or  commissions  to be
          received by the underwriters, dealers or agents;

     -    the terms of any indemnification provisions, including indemnification
          from liabilities under the federal securities laws; and

     -    the  nature  of any  transaction  by an  underwriter,  dealer or agent
          during the  offering  that is intended to  stabilize  or maintain  the
          market price of the common stock.

     In order to comply with certain state securities  laws, if applicable,  the
shares may be sold in such  jurisdictions  only through  registered  or licensed
brokers or  dealers.  In certain  states,  the shares may not be sold unless the
shares have been  registered or qualified for sale in such state or an exemption
from  regulation or  qualification  is available and is complied with.  Sales of
shares must also be made by us in  compliance  with all other  applicable  state
securities laws and regulations.

     MANNER OF SALES.  The  shares may be sold  according  to one or more of the
following methods.

     -    A block trade in which the broker or dealer so engaged will attempt to
          sell the shares as agent but may  position and resell a portion of the
          block as principal to facilitate the transaction.

     -    Purchases by a broker or dealer as principal  and resale by the broker
          or dealer for its account.

                                    Page 12


     -    Ordinary  brokerage  transactions and transactions in which the broker
          solicits purchasers.

     -    Pledges of shares to a broker-dealer or other person,  who may, in the
          event of default, purchase or sell the pledged shares.

     -    An exchange distribution under the rules of the exchange.

     -    In private transactions without a broker-dealer.

     -    By writing options.

     -    Any  combination  of the  foregoing,  or  any  other  available  means
          allowable under law.

     EXPENSES  ASSOCIATED  WITH  REGISTRATION.  We  will  pay  the  expenses  of
registering  the shares under the Securities  Act,  including  registration  and
filing  fees,  printing  expenses,   administrative  expenses,  legal  fees  and
accounting fees. If the shares are sold through  underwriters or broker-dealers,
we will be responsible for underwriting discounts,  underwriting commissions and
agent commissions.

     INDEMNIFICATION AND CONTRIBUTION.  Underwriters,  dealers, agents and other
persons may be entitled,  under  agreements that may be entered into with us, to
indemnification by us against certain civil liabilities,  including  liabilities
under the  Securities Act of 1933, or to  contribution  with respect to payments
which they may be required to make in respect of such liabilities.

     SUSPENSION OF THIS OFFERING.  We may suspend the use of this  prospectus if
we learn of any event that causes this prospectus to include an untrue statement
of material  fact or omit to state a material  fact required to be stated in the
prospectus or necessary to make the  statements in the prospectus not misleading
in light of the  circumstances  then existing.  If this type of event occurs,  a
prospectus  supplement  or  post-effective   amendment,  if  required,  will  be
distributed.

     Computershare  Trust Company,  Inc.,  formerly called  American  Securities
Transfer  & Trust,  Inc.,  located at 350  Indiana  Street,  Suite 800,  Golden,
Colorado, 80401 is the transfer agent and registrar for our common stock.

                                  LEGAL MATTERS

     Certain  legal  matters  with  respect to the  validity of the shares being
offered by the  prospectus  will be passed  upon by Henry T.  Meyer,  Esq.,  110
Marcus Drive, Melville, New York 11747. Mr. Meyer is Fonar's General Counsel.

                                     Experts

     The consolidated  financial statements and supplemental financial schedules
contained  in  Fonar's  latest  annual  report  on Form  10-K,  incorporated  by
reference into this prospectus,  have been audited by Marcum & Kliegman, LLP, to
the extent set forth in their report. Such consolidated financial statements and
schedules were included  therein in reliance upon their reports,  given on their
authority as experts in accounting and auditing.

                                 INDEMNIFICATION

     The Delaware  General  Corporation  Law and Fonar's by-laws provide for the
indemnification  of an officer or director under certain  circumstances  against
reasonable  expenses  incurred  in  connection  with the  defense  of any action
brought  against him by reason of his being a director  or  officer.  Insofar as
indemnification  for  liabilities  arising  under  the  Securities  Act  may  be
permitted to directors,  officers or other persons under Fonar's  by-laws or the
Delaware General Corporation Law, Fonar has been informed that in the opinion of
the Securities and Exchange  Commission such  indemnification  is against public
policy as expressed in the Securities Act and is therefore unenforceable.
