                          CERTIFICATE OF DESIGNATION OF
                     SERIES B CONVERTIBLE PREFERRED STOCK OF
                                VASOMEDICAL, INC.



     The  undersigned,  Anthony Viscusi and Joseph A. Giacalone,  hereby certify
that:

          I.   They are the duly elected and acting President and Secretary,
respectively, of Vasomedical, Inc., a Delaware corporation (the "Company").

          II.  The  Certificate  of  Incorporation  of  the  Company  authorizes
1,000,000 shares of preferred stock, par value $.01 per share, (of which 500,000
shares have been  designated as Class  Preferred  Stock,  Series A), of which no
shares are issued and outstanding.

          III.  The  following is a true and correct  copy of  resolutions  duly
adopted by the Board of Directors of the Company (the "Board of Directors") at a
meeting duly held June 6, 1997,  which  constituted all requisite  action on the
part of the Company for adoption of such resolutions.

                                   RESOLUTIONS

          WHEREAS,  the Board of  Directors  is  authorized  to provide  for the
issuance of shares of  preferred  stock from time to time in one or more series,
and by  filing a  certificate  pursuant  to the  applicable  law of the State of
Delaware,  to establish from time to time the number of shares to be included in
each  such  series,  and to fix or alter the  dividend  rights,  dividend  rate,
conversion  rights,  voting  rights,  rights  and terms of  redemption  (and any
sinking  fund  provisions),  redemption  price or  prices,  and the  liquidation
preferences of any wholly unissued series of preferred stock.

          WHEREAS, the Board of Directors desires,  pursuant to its authority as
aforesaid,  to  designate  a new series of  preferred  stock,  set the number of
shares constituting such series and fix the rights, preferences,  privileges and
restrictions of such series.

          NOW,  THEREFORE,  BE IT RESOLVED,  that the Board of Directors  hereby
designates a new series of preferred stock and the number of shares constituting
such  series and fixes the  rights,  preferences,  privileges  and  restrictions
relating to such series as follows:

<PAGE>

          Section 1. Designation,  Amount and Par Value. The series of preferred
stock  shall be  designated  as the Series B  Convertible  Preferred  Stock (the
"Preferred  Stock"),  and the  number of shares so  designated  shall be 150,000
(which  shall not be subject to  increase  without  the  consent of the  holders
thereof). Each share of Preferred Stock shall have a par value of $.01 per share
and a stated value of $20 per share (the "Stated Value").

          Section 2.     Dividends.

          (a) Holders of Preferred Stock shall be entitled to receive,  when and
as declared by the Board of Directors out of funds legally  available  therefor,
and the  Company  shall pay,  cumulative  dividends  at the rate per share (as a
percentage  of the Stated  Value per share) equal to 5% per annum,  payable,  in
cash or shares of Common Stock (in accordance  with the delivery terms hereof as
defined in Section 7) at the option of the Company, quarterly in arrears, but in
no event later than the Conversion Date (as hereinafter  defined)  applicable to
such share of Preferred  Stock in  accordance  with the delivery  terms  hereof.
Dividends on the  Preferred  Stock shall accrue  daily  commencing  the Original
Issue Date (as defined in Section 7), and shall be deemed to accrue on such date
whether or not earned or declared and whether or not there are profits,  surplus
or other funds of the Company legally available for the payment of dividends. If
dividends are to be paid in shares of Common  Stock,  the number of shares to be
issued shall equal the cash sum of the dividends divided by the Conversion Price
(as defined in Section  5(c)(i))  as of the date paid.  The party that holds the
Preferred Stock of record on an applicable  record date for any dividend payment
will be  entitled to receive  such  dividend  payment and any other  accrued and
unpaid  dividends  which accrued prior to such  dividend  payment date,  without
regard to any sale or  disposition  of such  Preferred  Stock  subsequent to the
applicable record date but prior to the applicable dividend payment date. Except
as  otherwise  provided  herein,  if at any time the Company  pays less than the
total amount of dividends then accrued on account of the Preferred  Stock,  such
payment shall be  distributed  ratably among the holders of the Preferred  Stock
based upon the number of shares held by each holder. Payment of dividends on the
Preferred  Stock is  further  subject  to the  provisions  of  Section  5(c)(i).
Notwithstanding  anything to the contrary contained herein, the Company may not,
without the written consent of the holders of a majority of the then outstanding
Preferred  Stock,  pay dividends in cash on the Preferred  Stock unless both the
payment  thereof and the retention of such paid cash by the holders is consented
to in writing free of any  subordination  prior  thereto by all lenders and debt
holders of the  Company  or by all  holders  of any class of  securities  of the
Company who by agreement have the right to consent to or force the subordination
of such payment.

          (b)  Notwithstanding  anything to the contrary  contained herein,  the
Company may not issue shares of Common  Stock in payment of dividends  (and must

<PAGE>

deliver cash in respect thereof) on the Preferred Stock if:

               (i) the number of shares of Common Stock at the time  authorized,
unissued  and  unreserved  for  all  purposes,  or held as  treasury  stock,  is
insufficient to issue such dividends to be paid in shares of Common Stock;

               (ii) such  shares are not  registered  for resale  pursuant to an
effective  registration statement that names the recipient of such dividend as a
selling  stockholder  thereunder or may not be sold without volume  restrictions
pursuant to Rule 144  promulgated  under the  Securities Act of 1933, as amended
(the  "Securities  Act"), as determined by counsel to the Company  pursuant to a
written  opinion  letter,  addressed  to  the  holder,  in  form  and  substance
acceptable to such holder;

               (iii) such  shares are not listed on the Nasdaq  SmallCap  Market
(or the American Stock  Exchange,  Nasdaq  National Market or The New York Stock
Exchange) and any other  exchange or quotation  system on which the Common Stock
is then listed for trading; or

               (iv) the issuance of such shares  would  result in the  recipient
thereof beneficially owning, in accordance with Rule 13d-3 promulgated under the
Securities  Exchange Act of 1934,  as amended (the  "Exchange  Act"),  more than
4.99% of the issued and outstanding shares of Common Stock.

          (c)  Notwithstanding   anything  to  the  contrary  contained  herein,
dividends  in  respect  of the  Preferred  Stock will cease to accrue if the Per
Share Market Value for any  consecutive 10 Trading Day period  commencing  after
the date that an Underlying Shares Registration Statement (as defined in Section
5) is  declared  effective  by  the  Securities  and  Exchange  Commission  (the
"Commission")  exceeds  the Initial  Conversion  Price by more than 50%. In such
event, dividends accrued through such date shall be due and payable.

          (d) So long as any Preferred Stock shall remain  outstanding,  neither
the Company nor any  subsidiary  thereof  shall  redeem,  purchase or  otherwise
acquire directly or indirectly any Junior  Securities (as defined in Section 7),
nor shall the Company directly or indirectly pay or declare any dividend or make
any distribution (other than a dividend or distribution  described in Section 5)
upon, nor shall any  distribution be made in respect of, any Junior  Securities,
nor shall any monies be set aside for or applied to the  purchase or  redemption
(through  a sinking  fund or  otherwise)  of any  Junior  Securities  unless all
accrued  and  unpaid  dividends  on the  Preferred  Stock for all past  dividend
periods shall have been paid.

          Section 3. Voting Rights.  Except as otherwise  provided herein and as
otherwise  required by law,  the  Preferred  Stock shall have no voting  rights.
However,  so long as any shares of Preferred Stock are outstanding,  the Company
shall not,  without  the  affirmative  vote of the  holders of a majority of the
shares of the Preferred Stock then  outstanding,  (a) alter or change  adversely
the powers,  preferences  or rights given to the Preferred  Stock,  (b) alter or
amend this  Certificate  of  Designation or (c) authorize or create any class of
stock ranking as to dividends or  distribution  of assets upon a Liquidation (as
defined in Section 4) senior to the Preferred Stock.

<PAGE>

          Section  4.   Liquidation.   Upon  any  liquidation,   dissolution  or
winding-up of the Company,  whether voluntary or involuntary (a  "Liquidation"),
the holders of Preferred Stock shall be entitled to receive out of the assets of
the  Company,  whether  such assets are  capital or  surplus,  for each share of
Preferred  Stock an amount equal to the Stated Value plus all accrued but unpaid
dividends per share, whether declared or not, before any distribution or payment
shall be made to the holders of any Junior Securities,  and if the assets of the
Company  shall be  insufficient  to pay in full such  amounts,  then the  entire
assets to be distributed to the holders of Preferred  Stock shall be distributed
among the holders of Preferred  Stock ratably in accordance  with the respective
amounts that would be payable on such shares if all amounts payable thereon were
paid in full. A sale,  conveyance or disposition of all or substantially  all of
the assets of the Company or the effectuation by the Company of a transaction or
series of related transactions in which more than 33% of the voting power of the
Company is disposed of, or a consolidation or merger of the Company with or into
any other  company  or  companies  shall not be treated  as a  Liquidation,  but
instead shall be subject to the  provisions of Section 5. The Company shall mail
written  notice  of any such  Liquidation,  not less  than 45 days  prior to the
payment date stated therein, to each record holder of Preferred Stock.

          Section 5.     Conversion.

          (a)(i)(A)  Each share of  Preferred  Stock shall be  convertible  into
shares of Common Stock (subject to reduction  pursuant to Section 5(a)(ii) below
and Section  4.10 of the  Purchase  Agreement  (as defined in Section 7)) at the
Conversion  Ratio (as defined in Section 7) at the option of the holder in whole
or in part at any time after the  earlier to occur of (A) the 90th day after the
Original Issue Date or (B) the date the Commission  declares effective under the
Securities Act, a registration statement contemplated by the Registration Rights
Agreement  (as  defined  in  Section  7) (the  "Underlying  Shares  Registration
Statement"). The holder shall effect conversions by surrendering the certificate
or  certificates  representing  the shares of Preferred Stock to be converted to
the Company,  duly endorsed or  accompanied  by a validly  executed stock power,
together with the form of conversion  notice  attached  hereto as Exhibit A (the
"Holder  Conversion  Notice").  Each Holder  Conversion Notice shall specify the
number of shares of Preferred  Stock to be converted  and the date on which such
conversion is to be effected, which date may not be prior to the date the Holder
Conversion Notice is deemed delivered  hereunder (the "Holder Conversion Date").
If no Holder  Conversion Date is specified in a Holder  Conversion  Notice,  the
Holder  Conversion  Date shall be the date that the Conversion  Notice  (defined
below) is deemed  delivered  pursuant to Section 5(h).  Subject to Sections 5(b)
and  5(a)(ii)  hereof and Section 4.10 of the  Purchase  Agreement,  each Holder
Conversion Notice, once given, shall be irrevocable. If the holder is converting
less than all  shares of  Preferred  Stock  represented  by the  certificate  or
certificates  tendered by the holder with the Holder Conversion  Notice, or if a
conversion  hereunder  cannot be effected  in full for any  reason,  the Company
shall  promptly  deliver  to such  holder (in the manner and within the time set
forth in Section  5(b)) a  certificate  for such  number of shares of  Preferred
Stock as have not been converted.

<PAGE>

               (B) After the third anniversary of the date the Underlying Shares
Registration Statement is declared effective by the Commission, which date shall
be extended by any days the Holder is unable to sell Underlying Shares under the
Underlying Shares  Registration  Statement as a result of (1) the failure of the
Underlying Shares Registration  Statement being effective and not subject to any
suspension  or  blackout,  (2) any action  taken by the Company to prevent  such
ability to sell  Underlying  Shares  under the  Underlying  Shares  Registration
Statement or (3) a delisting or suspension  of trading of the Common Stock,  the
Company may require the conversion of all or any portion of the then outstanding
and unconverted  shares of Preferred  Stock at the Conversion  Ratio (subject to
reduction  pursuant to Section  5(a)(ii)  below and Section 4.10 of the Purchase
Agreement) by  delivering  to the Holder of such shares to be converted  written
notice (the "Company Conversion Notice"),  provided, that, no such conversion is
permitted unless at the time of delivery of the Company Conversion Notice and on
the Company  Conversion Date (as defined  below),  (a) no less than 10 days have
passed  since  the  issuance  of any press  release  or other  public  statement
relating to such conversion,  (b) an Underlying  Shares  Registration  Statement
covering the resale of the shares of Common Stock issuable upon such  conversion
is effective and (c) the shares of Common Stock  issuable  upon such  conversion
are listed for trading on the Nasdaq  SmallCap  Market and any other exchange or
quotation  system on which the Common  Stock is then  listed for  trading.  Each
Company  Conversion Notice shall specify the number of shares of Preferred Stock
to be converted and the date on which such  conversion is to be effected,  which
date  may not be  prior to the day  after  the  Company  delivers  such  Company
Conversion  Notice by facsimile (the "Company  Conversion  Date"). If no Company
Conversion  Date is  specified  in a  Company  Conversion  Notice,  the  Company
Conversion Date shall be the date that the Conversion Notice is deemed delivered
pursuant to Section 5(h). A Holder Conversion Date and a Company Conversion Date
are  sometimes  referred  to  herein  as  the  "Conversion  Date"  and a  Holder
Conversion Notice and a Company Conversion Notice are sometimes referred to as a
"Conversion Notice." Any conversion pursuant to this Section 5(a)(i)(B) shall be
subject to Section 5(b) with respect to consequences of the Company's failure to
deliver shares of Common Stock in respect of a conversion under this Section. If
the Company is converting less than all shares of Preferred Stock represented by
the certificate or certificates  tendered by the Holder in response to a Company
Conversion  Notice, or if a conversion  hereunder cannot be effected in full for
any reason,  the Company shall promptly deliver to such tendering Holder (in the
manner and within the time set forth in  Section  5(b)) a  certificate  for such
number of shares as have not been converted.

               (ii)  Certain  Regulatory  Approval.  If on the  Conversion  Date
applicable to any  conversion  under this Section 5(a),  (A) the Common Stock is
then  listed for trading on the Nasdaq  National  Market or the  American  Stock
Exchange or if the rules of the Nasdaq  Stock  Market are  hereafter  amended to
extend  Rule  4460(i)  promulgated  thereby  (or any  successor  or  replacement
provision  thereof) to the Nasdaq  SmallCap  Market and the Common Stock is then

<PAGE>

listed for trading on such market,  (B) the  Conversion  Price then in effect is
such that the  aggregate  number of shares of Common  Stock  that  would then be
issuable upon conversion of all outstanding shares of Preferred Stock,  together
with any shares of Common Stock  previously  issued upon conversion of Preferred
Stock and in respect of payment of  dividends  hereunder,  would equal or exceed
20% of the number of shares of Common Stock  outstanding  on the Original  Issue
Date (the "Issuable  Maximum"),  and (C) the Company has not previously obtained
Shareholder  Approval (as defined  below),  then the Company  shall issue to the
converting  holder of the Preferred Stock the Issuable Maximum and, with respect
to any shares of Common Stock that  otherwise  would have been  issuable to such
holder in respect of the Conversion  Notice at issue or in respect of payment of
dividends hereunder in excess of the Issuable Maximum, the holder shall have the
option to require the Company to either (1) as promptly as  possible,  but in no
event later than 60 days after such  Conversion  Date,  convene a meeting of the
holders of the Common Stock and use its best  efforts to obtain the  Shareholder
Approval or (2) redeem,  from funds  legally  available  therefor at the time of
such  redemption,  the balance of the Preferred Stock subject to such Conversion
Notice at a price per share  equal to the  product  of (i) the Per Share  Market
Value for the Trading Day  immediately  preceding (1) the Conversion Date or (2)
the date of payment in full by the Company of the redemption price, whichever is
greater,  and (ii) the  Conversion  Ratio  calculated  on the  Conversion  Date;
provided,  however,  that if the holder has  requested  that the Company  obtain
Shareholder  Approval  under  paragraph  (1) above and the Company fails for any
reason to obtain such  Shareholder  Approval within the time period set forth in
(1) above,  the Company  shall be  obligated to redeem the  Preferred  Stock not
converted as a result of the  provisions of this Section in accordance  with the
provisions of paragraph (2) above, and in such case the interest contemplated by
the  immediately  succeeding  sentence  shall  be  deemed  to  accrue  from  the
Conversion  Date. If the holder has requested  that the Company redeem shares of
Preferred Stock pursuant to this Section and the Company fails for any reason to
pay the redemption  price under (2) above within seven days after the Conversion
Date,  the Company will pay interest on such  redemption  price at a rate of 15%
per  annum to the  converting  holder  of  Preferred  Stock,  accruing  from the
Conversion Date until the redemption  price plus any accrued interest thereon is
paid in full. The entire redemption price,  including interest thereon, shall be
paid in cash. Unless a greater vote is required by applicable law,  "Shareholder
Approval"  means the  approval  by a  majority  of the total  votes  cast on the
proposal, in person or by proxy, at a meeting of the shareholders of the Company
held in accordance with the Company's  Certificate of Incorporation and by-laws,
of the issuance by the Company of shares of Common Stock  exceeding the Issuable
Maximum as a consequence of the conversion of Preferred  Stock into Common Stock
at a price  less than the  greater of the book or market  value on the  Original
Issue Date as and to the extent required  pursuant to Rule 4460(i) of the Nasdaq
Stock Market or Rule 713 of the  American  Stock  Exchange (or any  successor or
replacement provision thereof), as applicable.

          (b) Not later than three Trading Days after the  Conversion  Date, the
Company will deliver to the converting  holder (i) a certificate or certificates
which shall be free of restrictive legends and trading  restrictions (other than
those required by Section  4.1(b) of the Purchase  Agreement)  representing  the
number of shares of Common Stock being acquired upon the conversion of shares of

<PAGE>

Preferred Stock (subject to reduction  pursuant to Section 5(a)(iii) and Section
4.10 of the Purchase  Agreement) and (ii) one or more certificates  representing
the number of shares of Preferred Stock not converted;  provided,  however, that
the Company shall not be obligated to issue  certificates  evidencing the shares
of Common Stock issuable upon  conversion of any shares of Preferred Stock until
certificates  evidencing such shares of Preferred Stock are either delivered for
conversion  to the  Company or any  transfer  agent for the  Preferred  Stock or
Common Stock duly endorsed or accompanied by a validly  executed stock power, or
the holder of such Preferred  Stock notifies the Company that such  certificates
have been lost,  stolen or  destroyed  and  provides  a bond (or other  adequate
security)  reasonably  satisfactory to the Company to indemnify the Company from
any  loss  incurred  by it in  connection  therewith.  If in  the  case  of  any
Conversion  Notice such  certificate  or  certificates,  including  for purposes
hereof,  any  shares of Common  Stock to be  issued  on the  Conversion  Date on
account of accrued but unpaid  dividends  hereunder,  are not delivered to or as
directed by the applicable  holder by the third Trading Day after the Conversion
Date,  the holder shall be entitled by written notice to the Company at any time
on or before its receipt of such  certificate  or  certificates  thereafter,  to
rescind such conversion, in which event the Company shall immediately return the
certificates representing the shares of Preferred Stock tendered for conversion.
If the Company fails to deliver to the holder such  certificate or  certificates
pursuant to this Section,  including for purposes  hereof,  any shares of Common
Stock to be issued on the  Conversion  Date on  account  of  accrued  but unpaid
dividends hereunder, prior to the expiration of the fourth Trading Day after the
Conversion  Date,  the Company shall pay to such holder,  in cash, as liquidated
damages and not as a penalty,  $1,500 for each day after such fourth Trading Day
until such  certificates  are delivered.  If the Company fails to deliver to the
holder such  certificate or  certificates  pursuant to this Section prior to the
20th day after the Conversion  Date, the Company shall,  at the holder's  option
(i)  redeem,  from  funds  legally  available  therefor  at  the  time  of  such
redemption,  such number of shares of Preferred  Stock then held by such holder,
as requested by such  holder,  and (ii) pay all accrued but unpaid  dividends on
account of the Preferred  Stock for which the Company shall have failed to issue
Common Stock  certificates  hereunder,  in cash. The redemption  price per share
shall be equal to the product of (A) the average Per Share  Market Value for the
five (5) Trading Days  immediately  preceding (1) the Conversion Date or (2) the
date of payment in full by the Company of such  redemption  price,  whichever is
greater, and (ii) the Conversion Ratio calculated on the Conversion Date. If the
holder has requested that the Company redeem shares of Preferred  Stock pursuant
to this Section and the Company fails for any reason to pay the redemption price
under (2) above within seven days after such notice is deemed delivered pursuant
to Section 5(h), the Company will pay interest on the redemption price at a rate
of 15% per annum,  in cash to such holder,  accruing from such seventh day until
the redemption price and any accrued interest thereon is paid in full.

          (c) (i) The  conversion  price for each share of Preferred  Stock (the
"Conversion  Price") in effect on any Conversion Date shall be the lesser of (a)
$2.18 (the  "Initial  Conversion  Price")  or (b) 85% of the  average of the Per
Share  Market  Value for the five (5) Trading  Days  immediately  preceding  the
Conversion  Date;  provided  that,  (a) if the  Underlying  Shares  Registration

<PAGE>

Statement  is not  filed on or prior to the 45th day after  the  Original  Issue
Date,  or (b) the  Company  fails to file  with the  Commission  a  request  for
acceleration in accordance with Rule 12d1-2  promulgated  under the Exchange Act
within  five (5) days of the date that the  Company  is  notified  (orally or in
writing,  whichever  is earlier) by the  Commission  that an  Underlying  Shares
Registration  Statement  will not be  "reviewed"  or is not  subject  to further
review  or  comment  by  the  Commission,   or  (c)  if  the  Underlying  Shares
Registration  Statement is not declared  effective by the Commission on or prior
to the 90th day after the Original Issue Date, or (d) if such Underlying  Shares
Registration  Statement is filed with and declared  effective by the  Commission
but thereafter ceases to be effective as to all Registrable  Securities (as such
term is defined in the Registration  Rights  Agreement) at any time prior to the
expiration  of the  "Effectiveness  Period"  (as  such  term as  defined  in the
Registration Rights Agreement),  without being succeeded within 10 Business Days
by a subsequent Underlying Shares Registration Statement filed with and declared
effective  by the  Commission,  or (e) if trading in the Common  Stock  shall be
suspended  for any  reason  for more  than  three  Trading  Days,  or (f) if the
conversion  rights of the holders of Preferred Stock hereunder are suspended for
any reason,  or (g) after an Underlying Shares  Registration  Statement has been
declared  effective by the Commission,  if holders of Preferred Stock are unable
to  utilize  an  Underlying  Shares  Registration  Statement  for the  resale of
Registrable Securities for an aggregate of ten (10) Trading Days in any 360 days
after the Original Issue Date (any such failure being referred to as an "Event,"
and for  purposes  of  clauses  (a),  (c) and (f) the date on which  such  Event
occurs,  or for purposes of clause (g) the Business Day after such Event occurs,
or for purposes of clause (b) the date on which such five
(5) days  period is  exceeded,  or for  purposes of clause (d) the date on which
such 10 Business Day-period is exceeded,  or for purposes of clause (e) the date
on which such three Trading Day period is exceeded,  being referred to as "Event
Date"),  the Conversion Price shall be decreased by 2.5% each month (i.e., 82.5%
as of the Event Date and 80% as of the one month  anniversary of the Event Date)
until the earlier to occur of the second month  anniversary after the Event Date
and such time as the  applicable  Event is cured.  Commencing  the second  month
anniversary  after the Event Date,  the Company  shall pay to the holders of the
Preferred Stock 2.5% of the  outstanding  amount of Preferred Stock (each holder
being  entitled  to receive  such  portion of such amount as equals its pro rata
portion of the Preferred Stock then outstanding) in cash as liquidated  damages,
and not as a penalty on the first day of each monthly  anniversary  of the Event
Date until such time as the  applicable  Event,  is cured.  Any  decrease in the
Conversion  Price  pursuant to this Section shall continue  notwithstanding  the
fact that the Event  causing such  decrease  has been  subsequently  cured.  The
provisions  of this  Section  are not  exclusive  and  shall in no way limit the
Company's  obligations under the Registration Rights Agreement.  Notwithstanding
anything to the  contrary  set forth  herein,  the Company may not,  without the
prior written consent of the holders,  pay liquidated  damages hereunder in cash
unless it shall have  received the prior  written  consent of all lenders of the
Company  or its  Affiliates  that have the right to require  such  consent or to
subordinate any such cash payment,  which consent shall provide that the payment
by the Company of any such  liquidated  damages  hereunder (and the retention of
such sum by the receiving holder) is not subject to any applicable subordination
rights of such lender.

               (ii) If the  Company,  at any time while any shares of  Preferred
Stock are  outstanding,  (a)  shall pay a stock  dividend  or  otherwise  make a
distribution  or  distributions  on shares of its Junior  Securities  payable in
shares of Common Stock, (b) subdivide  outstanding shares of Common Stock into a
larger number of shares,  (c) combine  outstanding shares of Common Stock into a

<PAGE>

smaller number of shares, or (d) issue by reclassification of shares (other than
a stock  split or  reverse  stock  split) of Common  Stock any shares of capital
stock of the Company,  the Initial  Conversion  Price shall be  multiplied  by a
fraction of which the  numerator  shall be the number of shares of Common  Stock
(excluding  treasury shares, if any) outstanding  before such event and of which
the denominator  shall be the number of shares of Common Stock outstanding after
such event.  Any adjustment made pursuant to this Section  5(c)(ii) shall become
effective   immediately   after  the  record  date  for  the   determination  of
stockholders  entitled to receive such dividend or distribution and shall become
effective  immediately  after the effective  date in the case of a  subdivision,
combination or re-classification.

               (iii) If the  Company,  at any time while any shares of Preferred
Stock are  outstanding,  shall issue rights or warrants to all holders of Common
Stock  entitling  them to subscribe for or purchase  shares of Common Stock at a
price per share  less than the Per  Share  Market  Value of Common  Stock at the
record date mentioned below, the Initial Conversion Price shall be multiplied by
a  fraction,  of which the  denominator  shall be the number of shares of Common
Stock (excluding treasury shares, if any) outstanding on the date of issuance of
such rights or warrants  plus the number of  additional  shares of Common  Stock
offered for  subscription  or purchase,  and of which the numerator shall be the
number of shares of Common Stock (excluding treasury shares, if any) outstanding
on the date of issuance  of such  rights or  warrants  plus the number of shares
which the  aggregate  offering  price of the total  number of shares so  offered
would  purchase at such Per Share Market Value.  Such  adjustment  shall be made
whenever  such  rights  or  warrants  are  issued,  and shall  become  effective
immediately after the record date for the determination of stockholders entitled
to receive such rights or warrants. However, upon the expiration of any right or
warrant to purchase Common Stock the issuance of which resulted in an adjustment
in the Initial Conversion Price pursuant to this Section 5(c)(iii),  if any such
right or warrant  shall  expire and shall not have been  exercised,  the Initial
Conversion  Price shall  immediately  upon such  expiration  be  recomputed  and
effective  immediately  upon such  expiration be increased to the price which it
would have been (but reflecting any other adjustments in the Initial  Conversion
Price made  pursuant to the  provisions  of this Section 5 after the issuance of
such rights or warrants) had the adjustment of the Initial Conversion Price made
upon the issuance of such rights or warrants  been made on the basis of offering
for subscription or purchase only that number of shares of Common Stock actually
purchased upon the exercise of such rights or warrants actually exercised.

               (iv) If the Company,  at any time while shares of Preferred Stock
are  outstanding,  shall  distribute  to all holders of Common Stock (and not to
holders of Preferred Stock) evidences of its indebtedness or assets or rights or
warrants to subscribe for or purchase any security  (excluding those referred to
in  Sections  5(c)(ii)  and (iii)  above),  then in each  such case the  Initial
Conversion  Price at which each share of  Preferred  Stock shall  thereafter  be

<PAGE>

convertible  shall be determined by multiplying the Initial  Conversion Price in
effect  immediately  prior  to  the  record  date  fixed  for  determination  of
stockholders  entitled to receive such  distribution  by a fraction of which the
denominator shall be the Per Share Market Value of Common Stock determined as of
the record date mentioned  above,  and of which the numerator  shall be such Per
Share  Market  Value of the Common  Stock on such record date less the then fair
market  value at such  record  date of the portion of such assets or evidence of
indebtedness so distributed  applicable to one outstanding share of Common Stock
as determined by the Board of Directors in good faith;  provided,  however, that
in the event of a distribution  exceeding ten percent (10%) of the net assets of
the  Company,  such  fair  market  value  shall be  determined  by a  nationally
recognized  or major  regional  investment  banking firm or firm of  independent
certified public accountants of recognized  standing (which may be the firm that
regularly  examines the financial  statements  of the Company) (an  "Appraiser")
selected in good faith by the holders of a majority in interest of the shares of
Preferred Stock then outstanding; and provided, further, that the Company, after
receipt of the determination by such Appraiser shall have the right to select an
additional  Appraiser,  in good faith, in which case the fair market value shall
be equal to the average of the determinations by each such Appraiser.  In either
case the adjustments  shall be described in a statement  provided to the holders
of  Preferred  Stock of the portion of assets or evidences  of  indebtedness  so
distributed or such subscription rights applicable to one share of Common Stock.
Such adjustment  shall be made whenever any such  distribution is made and shall
become effective immediately after the record date mentioned above.

               (v) All  calculations  under this  Section 5 shall be made to the
nearest cent or the nearest 1/100th of a share, as the case may be.

               (vi) Whenever the Initial  Conversion Price is adjusted  pursuant
to Section  5(c)(ii),(iii)  or (iv),  the Company  shall  promptly  mail to each
holder of Preferred  Stock, a notice setting forth the Initial  Conversion Price
after such adjustment and setting forth a brief statement of the facts requiring
such adjustment.

               (vii) In case of any  reclassification  (which,  for  purposes of
this Section  5(c)(vii),  does not include a stock split or reverse stock split)
of the Common  Stock,  any  consolidation  or merger of the Company with or into
another person  pursuant to which the Company will not be the surviving  entity,
the sale or transfer of all or substantially all of the assets of the Company or
any compulsory  share  exchange  pursuant to which the Common Stock is converted
into other securities, cash or property, the holders of the Preferred Stock then
outstanding  shall have the right  thereafter  to, at their option,  (A) convert
such  shares  only  into the  shares of stock  and  other  securities,  cash and
property  receivable  upon or  deemed  to be held by  holders  of  Common  Stock
following such reclassification,  consolidation, merger, sale, transfer or share
exchange,  and the holders of the  Preferred  Stock shall be entitled  upon such
event to receive  such amount of  securities,  cash or property as the shares of
the Common Stock of the Company into which such shares of Preferred  Stock could
have been converted immediately prior to such  reclassification,  consolidation,
merger, sale, transfer or share exchange would have been entitled or (B) require
the Company to redeem, from funds legally available therefor at the time of such

<PAGE>

redemption,  its  shares of  Preferred  Stock at a price per share  equal to the
product of (i) the average Per Share  Market Value for the five (5) Trading Days
immediately  preceding (1) the effective date or the date of the closing, as the
case may be, of the reclassification,  consolidation,  merger, sale, transfer or
share exchange the triggering such  redemption  right or (2) the date of payment
in full by the Company of the redemption price hereunder,  whichever is greater,
and (ii) the  Conversion  Ratio  calculated  on the date of the  closing  or the
effective  date,  as the case may be,  of the  reclassification,  consolidation,
merger,  sale,  transfer or share exchange  triggering such redemption right, as
the case may be.  The entire  redemption  price  shall be paid in cash,  and the
terms of payment of such redemption price shall be subject to the provisions set
forth in Section 6. The terms of any such consolidation,  merger, sale, transfer
or share  exchange  shall  include  such terms so as to  continue to give to the
holder of Preferred Stock the right to receive the securities,  cash or property
set forth in this Section 5(c)(vii) upon any conversion or redemption  following
such consolidation,  merger,  sale,  transfer or share exchange.  This provision
shall similarly apply to successive reclassifications,  consolidations, mergers,
sales, transfers or share exchanges.

               (viii)   If:

                    A.  the Company shall declare a dividend (or any other
                        distribution) on its Common Stock; or

                    B.  the Company shall declare a special nonrecurring cash
                        dividend on or a redemption of its Common Stock; or

                    C.  the Company shall authorize the granting to all holders 
                        of the Common Stock rights or warrants to subscribe for 
                        or purchase any shares of capital stock of any class or 
                        of any rights; or

                    D.  the approval of any stockholders of the Company shall be
                        required in connection with any  reclassification of the
                        Common Stock of the Company, any consolidation or merger
                        to which the Company is a party, any sale or transfer of
                        all or  substantially  all of the assets of the Company,
                        of any compulsory  share of exchange  whereby the Common
                        Stock  is  converted  into  other  securities,  cash  or
                        property; or

                    E.  the Company shall authorize the voluntary or involuntary
                        dissolution, liquidation or winding up of the affairs 
                        of the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of  conversion of Preferred  Stock,  and shall cause to be mailed to
the holders of Preferred Stock at their last addresses as they shall appear upon
the  stock  books  of the  Company,  at  least  30  calendar  days  prior to the

<PAGE>

applicable record or effective date hereinafter  specified, a notice stating (x)
the date on which a record  is to be taken  for the  purpose  of such  dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the  holders of Common  Stock of record to be  entitled  to
such  dividend,  distributions,   redemption,  rights  or  warrants  are  to  be
determined  or (y)  the  date on  which  such  reclassification,  consolidation,
merger,  sale,  transfer or share  exchange is expected to become  effective  or
close,  and the date as of which it is expected  that holders of Common Stock of
record  shall  be  entitled  to  exchange  their  shares  of  Common  Stock  for
securities,  cash or other  property  deliverable  upon  such  reclassification,
consolidation, merger, sale, transfer or share exchange; provided, however, that
the failure to mail such notice or any defect therein or in the mailing  thereof
shall not affect the validity of the corporate  action  required to be specified
in such notice. Holders are entitled to convert shares of Preferred Stock during
the 30-day period  commencing  the date of such notice to the effective  date of
the event triggering such notice.

          (d) The Company  covenants  that it will at all times reserve and keep
available out of its authorized and unissued Common Stock solely for the purpose
of issuance  upon  conversion  of  Preferred  Stock and payment of  dividends on
Preferred  Stock,  each as herein provided,  free from preemptive  rights or any
other actual  contingent  purchase  rights of persons  other than the holders of
Preferred  Stock,  not less than such number of shares of Common  Stock as shall
(subject to any additional requirements of the Company as to reservation of such
shares set forth in the Purchase Agreement) be issuable (taking into account the
adjustments  and  restrictions  of  Section  5(c))  upon the  conversion  of all
outstanding  shares of Preferred Stock and payment of dividends  hereunder.  The
Company  covenants  that all shares of Common  Stock  that shall be so  issuable
shall,  upon  issue,  be duly and  validly  authorized,  issued and fully  paid,
nonassessable and freely tradeable.

          (e) Upon a conversion  hereunder  the Company shall not be required to
issue stock certificates  representing  fractions of shares of Common Stock, but
may if otherwise permitted, make a cash payment in respect of any final fraction
of a share  based on the Per Share  Market  Value at such time.  If the  Company
elects not, or is unable, to make such a cash payment,  the holder of a share of
Preferred Stock shall be entitled to receive, in lieu of the final fraction of a
share, one whole share of Common Stock.

          (f) The  issuance  of  certificates  for  shares  of  Common  Stock on
conversion  of  Preferred  Stock  shall be made  without  charge to the  holders
thereof  for any  documentary  stamp or  similar  taxes  that may be  payable in
respect of the issue or delivery of such certificate,  provided that the Company
shall not be  required  to pay any tax that may be  payable  in  respect  of any
transfer  involved in the  issuance and  delivery of any such  certificate  upon
conversion  in a name other than that of the holder of such shares of  Preferred
Stock so converted.

          (g) Shares of  Preferred  Stock  converted  into Common Stock shall be
canceled  and  shall  have the  status  of  authorized  but  unissued  shares of
undesignated stock.

          (h) Any and all notices or other  communications  or  deliveries to be
provided by the holders of the Preferred  Stock  hereunder,  including,  without
limitation, any Conversion Notice, shall be in writing and delivered personally,

<PAGE>

by facsimile,  sent by a nationally recognized overnight courier service or sent
by certified or registered mail, postage prepaid,  addressed to the attention of
the Chief Executive Officer of the Company at the facsimile  telephone number or
address of the  principal  place of  business of the Company as set forth in the
Purchase Agreement. Any and all notices or other communications or deliveries to
be  provided  by  the  Company  hereunder  shall  be in  writing  and  delivered
personally,  by facsimile,  sent by a nationally  recognized  overnight  courier
service or sent by certified or registered mail,  postage prepaid,  addressed to
each holder of Preferred Stock at the facsimile  telephone  number or address of
such  holder  appearing  on the books of the  Company,  or if no such  facsimile
telephone number or address  appears,  at the principal place of business of the
holder.  Any notice or other  communication  or  deliveries  hereunder  shall be
deemed given and effective on the earliest of (i) the date of  transmission,  if
such  notice or  communication  is  delivered  via  facsimile  at the  facsimile
telephone  number  specified in this Section prior to 4:30 p.m.  (Eastern Time),
(ii) the date after the date of transmission, if such notice or communication is
delivered  via  facsimile at the facsimile  telephone  number  specified in this
Section later than 4:30 p.m.  (Eastern  Time) on any date and earlier than 11:59
p.m.  (Eastern  Time) on such date,  (iii) four days after deposit in the United
States mails,  (iv) the Business Day  following the date of mailing,  if send by
nationally  recognized  overnight courier service, or (v) upon actual receipt by
the party to whom such notice is required to be given.

          Section 6.    Redemption.

          The  Company  shall  have the right,  exercisable  at any time upon 20
Trading  Days  notice to the  holders of the  Preferred  Stock given at any time
after the Original Issue Date to redeem,  from funds legally available  therefor
at the time of such  redemption,  all or any portion of the shares of  Preferred
Stock which have not previously been converted or redeemed, at a price per share
equal to the product of (i) the average Per Share  Market Value for the five (5)
Trading  Days  immediately  preceding  (1)  the  date of the  redemption  notice
referenced  above  or (2) the  date of  payment  in full by the  Company  of the
redemption price hereunder,  whichever is greater, and (ii) the Conversion Ratio
calculated on the date of such redemption  notice.  The entire  redemption price
shall be paid in cash.  Holders of  Preferred  Stock may  convert  any shares of
Preferred  Stock,  including  shares subject to a redemption  notice given under
this Section,  during the period from the date of such redemption notice through
the 19th Trading Day thereafter.

          If any portion of the redemption price under this Section shall not be
paid by the Company within seven (7) calendar days after the date due,  interest
shall  accrue  thereon at the rate of 15% per annum until the  redemption  price
plus all such interest is paid in full (which amount shall be paid as liquidated
damages and not as a penalty).  In addition,  if any portion of such  redemption
price  remains  unpaid  for more than 7 calendar  days  after the date due,  the
holder of the Preferred  Stock subject to such  redemption may elect, by written
notice to the  Company  given  within 30 days after the date due,  to either (i)

<PAGE>

demand conversion in accordance with the formula and the time frame therefor set
forth in  Section 5 of all of the  shares  of  Preferred  Stock  for which  such
redemption price, plus accrued liquidated damages thereof,  has not been paid in
full (the "Unpaid Redemption Shares"), in which event the Per Share Market Price
for such shares shall be the lower of the Per Share Market Price  calculated  on
the date such redemption price was originally due and the Per Share Market Price
as of the holder's  written demand for conversion,  or (ii) invalidate ab initio
such redemption,  notwithstanding  anything herein contained to the contrary. If
the holder elects  option (i) above,  the Company shall within three (3) Trading
Days of its receipt of such election  deliver to the holder the shares of Common
Stock issuable upon conversion of the Unpaid  Redemption  Shares subject to such
holder conversion  demand and otherwise  perform its obligations  hereunder with
respect  thereto;  or, if the Holder elects option (ii) above, the Company shall
promptly, and in any event not later than three (3) Trading Days from receipt of
holder's  notice  of such  election,  return  to the  holder  all of the  Unpaid
Redemption  Shares.  Notwithstanding  anything to the contrary contained herein,
the Company may not, without the written consent of the holder, redeem shares of
Preferred  Stock unless both the payment  thereof and the retention of such paid
cash by the holder is consented to in writing  free of any  subordination  prior
thereto by all lenders of the Company who by agreement have the right to consent
to or force the subordination of such payment.

         Section 3.1. Representations and Warranties of the Company. The Company
hereby represents and warrants to the Purchaser as follows:

<PAGE>

         (a) Organization and Qualification.  The Company is a corporation, duly
incorporated,  validly  existing  and in good  standing  under  the  laws of the
jurisdiction  of its  incorporation,  with the  requisite  corporate  power  and
authority to own and use its  properties and assets and to carry on its business
as currently conducted.  The Company has no subsidiaries other than as set forth
in the SEC Documents or in Schedule 3.1(a)  (collectively,  the "Subsidiaries").
Each of the Subsidiaries is a corporation,  duly incorporated,  validly existing
and in good standing under the laws of the  jurisdiction  of its  incorporation,
with the requisite  corporate  power and authority to own and use its properties
and assets and to carry on its  business  as  currently  conducted.  Each of the
Company and the  Subsidiaries  is duly  qualified  to do business and is in good
standing as a foreign  corporation in each  jurisdiction  in which the nature of
the  business  conducted  or  property  owned  by it  makes  such  qualification
necessary,  except where the failure to be so qualified or in good standing,  as
the case may be, could not,  individually  or in the  aggregate,  (x)  adversely
affect  the  legality,   validity  or  enforceability  of  this  Agreement,  the
Certificate of Designation,  the Warrant,  the Registration  Rights Agreement or
the  Side  Letter,  (collectively,  the  "Transaction  Documents"),  (y)  have a
material  adverse effect on the results of  operations,  assets,  prospects,  or
financial condition of the Company and the Subsidiaries, taken as a whole or (z)
adversely impair in any material  respect with the Company's  ability to perform
fully on a timely basis its obligations  under the Transaction  Documents or the
Securities (a "Material Adverse Effect").

         (b) Authorization; Enforcement. The Company has the requisite corporate
power  and  authority  to  enter  into  and  to  consummate   the   transactions
contemplated  by the  Transaction  Documents  and to  otherwise  carry  out  its
obligations under the Transaction Documents.  The execution and delivery of each
of the  Transaction  Documents by the Company and the  consummation by it of the
transactions  contemplated  thereby have been duly  authorized  by all necessary
action  on the part of the  Company,  including,  without  limitation,  approval
thereof by the Company's Board of Directors.  Each of the Transaction  Documents
has been duly executed and delivered by the Company and  constitutes  the legal,
valid and binding obligation of the Company  enforceable  against the Company in
accordance  with its  terms,  except as such  enforceability  may be  limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium, liquidation or
similar laws relating to, or affecting  generally the enforcement of, creditors'
rights and remedies or by other  equitable  principles  of general  application.
Neither the Company nor any  Subsidiary is in violation of any of the provisions
of  its  respective  certificate  of  incorporation,  bylaws  or  other  charter
documents,  which could  adversely  affect the  execution,  delivery  and timely
performance of the Transaction Documents.

         (c)  Capitalization.  The authorized,  issued and  outstanding  capital
stock of the  Company  and each of the  Subsidiaries  is set  forth in  Schedule
3.1(c).  No shares of Common Stock are entitled to preemptive or similar rights.
Except as specifically  disclosed in Schedule  3.1(c),  there are no outstanding

<PAGE>

options,  warrants,  script rights to subscribe to, calls or  commitments of any
character  whatsoever  relating  to, or,  except as a result of the purchase and
sale of the Shares and the Warrant hereunder,  securities, rights or obligations
convertible  into or  exchangeable  for,  or  giving  any  Person  any  right to
subscribe for or acquire any shares of Common Stock, or contracts,  commitments,
understandings, or arrangements by which the Company or any Subsidiary is or may
become bound to issue additional shares of Common Stock, or securities or rights
convertible or exchangeable into shares of Common Stock. To the knowledge of the
Company without independent  investigation,  except as specifically disclosed in
the SEC Documents or Schedule 3.1(c), no Person beneficially owns (as determined
pursuant to Rule 13d-3  promulgated  under the Exchange Act) or has the right to
acquire by agreement with or by obligation  binding upon the Company  beneficial
ownership of in excess of 5% of the Common Stock.

         (d) Issuance of Shares,  Warrant and Underlying  Shares. The Shares and
the Warrant have been duly  authorized and, when paid for in accordance with the
terms hereof,  shall be validly issued,  fully paid and nonassessable,  free and
clear of any Liens. The Company has and at all times while any Shares are or the
Warrant is  outstanding  will  maintain  a reserve of shares of Common  Stock to
enable it to perform its conversion and other  obligations under this Agreement,
the Certificate of Designation and Warrant,  which reserve shall be no less than
6,683,464  shares of Common Stock (such sum, the "Initial  Reserve").  If at any
time  the sum of the  number  of  shares  of  Common  Stock  issuable  (a)  upon
conversion  in  full of the  then  outstanding  Shares,  (b) as the  payment  of
dividends on account of the Shares and (c) upon  exercise in full of the Warrant
exceeds  the Initial  Reserve,  then the Company  shall duly  reserve  twice the
number  of  shares  of  Common  Stock  equal  to such  excess  to  fulfill  such
obligations. When issued in accordance with the terms hereof, the Certificate of
Designation  and the Warrant (as the case may be),  the  Underlying  Shares will
have been duly authorized,  validly issued,  fully paid and  nonassessable,  and
free and clear of any Liens.

         (e) No  Conflicts.  The  execution,  delivery  and  performance  of the
Transaction  Documents by the Company and the consummation by the Company of the
transactions  contemplated  thereby  do not and  will not (i)  conflict  with or
violate any provision of its  certificate  of  incorporation  or bylaws (each as
amended  through the date hereof) or (ii) conflict with, or constitute a default
(or an event which with notice or lapse of time or both would  become a default)
under, or give to others any rights of termination,  amendment,  acceleration or
cancellation  of, any agreement,  indenture,  loans or credit agreement or other
instrument  to which the Company is a party,  or (iii)  result in a violation of
any  law,  rule,  regulation,  order,  judgment,  injunction,  decree  or  other
restriction  of any court or United States  governmental  authority to which the
Company  is  subject   (including   Federal  and  state   securities   laws  and
regulations),  or by which  any  property  or asset of the  Company  is bound or
affected,  except in the case of each of clauses (ii) and (iii), such conflicts,
defaults, terminations, amendments, accelerations,  cancellations and violations
as would not,  individually or in the aggregate,  have or reasonably be expected
to result in a Material Adverse Effect. The business of the Company is not being
conducted in violation of any law,  ordinance or regulation of any  governmental
authority,  except for possible  violations which either  individually or in the
aggregate  would not have or  reasonably  be  expected  to result in a  Material
Adverse Effect.

<PAGE>

         (f) Consents and  Approvals.  Neither the Company nor any Subsidiary is
required to obtain any consent,  waiver,  authorization or order of, or make any
filing or registration  with, any court or other Federal,  state, local or other
governmental  authority  or other  Person  in  connection  with  the  execution,
delivery and performance by the Company of the Transaction Documents, except for
(i) the filing of the Certificate of Designation with respect to the Shares with
the  Secretary of State of Delaware,  which filing shall be effected on or prior
to the Closing Date, (ii) the filing of the registration  statement covering the
Underlying  Shares (the  "Underlying  Shares  Registration  Statement") with the
Commission  and the  making  of the  applicable  blue-sky  filings  under  state
securities laws, each as contemplated by the Registration Rights Agreement,  and
(iii) other than, in all other cases,  where the failure to obtain such consent,
waiver,  authorization or order, or to give or make such notice or filing, would
not,  individually or in the aggregate,  have or would reasonably be expected to
result in a Material Adverse Effect (the "Required Approvals").

         (g) Litigation;  Proceedings. Except as set forth in the SEC Documents,
there is no action,  suit,  notice of  violation,  proceeding  or  investigation
pending  or,  to the  best  knowledge  of the  Company,  threatened  against  or
affecting  the  Company or any of its  Subsidiaries  or any of their  respective
properties  before or by any court,  governmental  or  administrative  agency or
regulatory authority (Federal, state, county, local or foreign) which relates to
or  challenges  the  legality,  validity or  enforceability  of the  Transaction
Documents or the  Securities or which would,  individually  or in the aggregate,
have or reasonably be expected to result in a Material Adverse Effect.

         (h) No Default or Violation. Neither the Company nor any Subsidiary (i)
is in default under or in violation  (or has received  notice of a claim that it
is in default under or in violation) of any indenture,  loan or credit agreement
or any other  agreement or  instrument  to which it is a party or by which it or
any of its properties is bound,  (ii) is in violation of any order of any court,
arbitrator or governmental  body, or (iii) is in violation of any statute,  rule
or regulation of any governmental authority, except as would not, in any case of
(i) and (iii) above,  individually  or in the  aggregate,  have or reasonably be
expected to result in a Material Adverse Effect.

         (i) Certain Fees.  Except for fees payable to Wharton Capital Partners,
Ltd.  no fees or  commissions  will be  payable by the  Company  to any  broker,
financial  advisor,  finder,  investment  banker,  or bank with  respect  to the
transactions  contemplated  by  this  Agreement.  The  Purchaser  shall  have no
obligation with respect to such fees or with respect to any claims made by or on
behalf of other Persons for fees of a type contemplated in this Section that may
be due in connection with the transactions  contemplated by this Agreement.  The
Company  shall  indemnify  and  hold  harmless  the  Purchaser,  its  employees,
officers,  directors,  agents, and partners, and their respective Affiliates (as
such term is defined under Rule 405 promulgated  under the Securities Act), from
and  against  all  claims,  losses,  damages,  costs  (including  the  costs  of
preparation  and attorney's  fees) and expenses  suffered in respect of any such
claimed or existing fees, except to the extent such fees or claims result from a
written agreement executed by the Purchaser and such claimant in connection with
the transactions contemplated hereby.

misleading.

         (k) Private Offering.  Neither the Company nor any Person acting on its
behalf has taken or will take any action  (including,  without  limitation,  any
offering of securities of the Company  under  circumstances  which would require
the  integration  of such  offering  with  the  offering  of the  Shares  or the
Underlying  Shares under the  Securities  Act) which might subject the offering,
issuance  or sale of the  Shares or the  Underlying  Shares to the  registration

being collectively referred to herein as the "SEC Documents") on a timely basis,
or has  received a valid  extension of such time of filing (in which case it has
made all such  filings  in the time  required  by such  extension).  As of their
respective  filing dates,  the SEC Documents  complied in all material  respects
with the requirements of the Securities Act or the Exchange Act, as the case may
be,  and the  published  rules and  regulations  of the  Commission  promulgated
thereunder,  and none of the SEC  Documents,  when filed,  contained  any untrue

thereto or, in the case of unaudited interim statements,  to the extent they may
include footnotes or may be condensed as summary statements,  and fairly present
in all  material  respects  the  financial  position  of  the  Company  and  its
consolidated  subsidiaries  as of and for the dates  thereof  and the results of
operations  and cash flows for the periods then ended,  subject,  in the case of
unaudited  statements,  to normal year-end audit  adjustments.  The Company last
filed audited  financial  statements with the Commission on August 29, 1996, and
the Company has not received any comments from the Commission in respect of such
audited  financial  statements.  Since  the  date  of the  financial  statements

event, occurrence or development that has had, would have or could reasonably be
expected  to result  in a  Material  Adverse  Effect  which is not  specifically
disclosed in the Disclosure Materials.

market.

         (r)  Use of Proceeds.  The Company shall use all of the proceeds from 
the placement of the securities offered hereby for working capital purposes

application,  the Company will invest such proceeds in interest bearing accounts
and short-term, interest bearing securities.

existing  infringement  by another  Person of any of the  Intellectual  Property
Rights which are necessary for use in connection with its business.

         Section 3.2.  Representations  and  Warranties  of the  Purchaser.  The
Purchaser hereby represents and warrants to the Company as follows:

         (a)  Organization;  Authority.  The Purchaser is a corporation duly and
validly  existing and in good standing under the laws of the jurisdiction of its
incorporation.  The Purchaser has the requisite corporate power and authority to
enter into and to consummate  the  transactions  contemplated  hereby and by the
Registration  Rights  Agreement,  the  Escrow  Agreement  and  the  Warrant  and
otherwise to carry out its obligations hereunder and thereunder. The purchase of

<PAGE>

the  Securities  by the  Purchaser  hereunder  has been duly  authorized  by all
necessary  action  on the part of the  Purchaser.  Each of this  Agreement,  the
Registration  Rights  Agreement and the Escrow  Agreement has been duly executed
and  delivered by or on behalf of the Purchaser  and  constitutes  the valid and
legally  binding  obligation  of  the  Purchaser,   enforceable  against  it  in
accordance  with  its  terms,  subject  to  bankruptcy,  insolvency,  fraudulent
transfer,  reorganization,  moratorium and similar laws of general applicability
relating to or affecting  creditors' rights generally and to general  principles
of equity.

         (b)  Investment  Intent.  The Purchaser is acquiring the Securities for
its own account (and/or on behalf of managed accounts who are purchasing  solely
for their own accounts for investment) for investment purposes only and not with
a view to or for distributing or reselling the Securities or any part thereof or
interest therein, without prejudice,  however, to the Purchaser's right, subject
to the  provisions  of the  Transaction  Documents,  at all  times  to  sell  or
otherwise  dispose  of all or any  part of the  Securities  under  an  effective
registration   statement  under  the  Securities  Act  and  in  compliance  with
applicable  State  securities  laws or under an exemption or exclusion from such
registration.

         (c) Purchaser  Status.  At the time the Purchaser  (and any account for
which it is  purchasing)  was  offered the Shares and the  Warrant,  it (and any
managed account for which it is purchasing) was, and at the date hereof, it (and
any managed  account for which it is purchasing) is, and at the Closing Date, it
(and any managed  account for which it is  purchasing)  will be, an  "accredited
investor" as defined in Rule 501(a) under the Securities Act.

         (d) Experience of Purchaser.  The  Purchaser,  either alone or together
with its representatives,  has such knowledge,  sophistication and experience in
business and financial  matters so as to be capable of evaluating the merits and
risks of the prospective investment in the Securities,  and has so evaluated the
merits and risks of such investment.

         (e) Ability of Purchaser to Bear Risk of  Investment.  The Purchaser is
able to bear the economic risk of an investment  in the  Securities  and, at the
present time, is able to afford a complete loss of such investment.

         (f) Access to Information.  The Purchaser  acknowledges  receipt of the
Disclosure Materials and further acknowledges that it or its representatives has
been  afforded  (i) the  opportunity  to ask  such  questions  as it has  deemed
necessary  of, and to  receive  answers  from,  representatives  of the  Company
concerning  the terms and  conditions of the offering of the  Securities and the
merits and risks of an investment therein;  (ii) access to information about the
Company and the Company's financial condition, results of operations,  business,
properties and management  sufficient to enable it to evaluate such  investment;
and (iii)  the  opportunity  to obtain  such  additional  information  which the
Company possesses or can acquire without  unreasonable effort or expense that is
necessary  to  make  an  informed   investment  decision  with  respect  to  the
Securities.

<PAGE>

         (g)  Manner  of  Sale.  At no  time  was  Purchaser  presented  with or
solicited  by or through any leaflet,  public  promotional  meeting,  television
advertisement  or any other  form of  general  solicitation  or  advertising  in
connection with its purchase of the Shares or the Warrant.

         (h) Reliance.  The Purchaser  understands and acknowledges that (i) the
Shares and the Warrant are being offered and sold, and the Underlying Shares are
being offered, to it without  registration under the Securities Act in a private
placement that is exempt from the registration  provisions of the Securities Act
and (ii) the  availability  of such  exemption  depends in part on, and that the
Company  will  rely  upon  the  accuracy  and  truthfulness  of,  the  foregoing
representations and the Purchaser hereby consents to such reliance.

         The  Company  acknowledges  and  agrees  that  the  Purchaser  makes no
representation or warranty with respect to the transactions  contemplated hereby
other than those specifically set forth in this Section 3.2.


                                   ARTICLE IV

                         OTHER AGREEMENTS OF THE PARTIES

         Section 4.1. Transfer Restrictions.  (a) If the Purchaser should decide
to  dispose  of any of the  Shares  or any  portion  of the  Warrant  (and  upon
conversion or exercise thereof, as the case may be, any Underlying Shares),  the
Purchaser understands and agrees that it may do so only pursuant to an effective
registration  statement  under the Securities Act, to the Company or pursuant to
an available exemption from the registration requirements thereof. In connection
with any transfer of any of the  Securities  other than pursuant to an effective
registration statement or to the Company, the Company may require the transferor
of such  Securities to provide to the Company an opinion of counsel  experienced
in the area of United States  securities  laws selected by the  transferor,  the
form and  substance of which opinion  shall be  reasonably  satisfactory  to the
Company, to the effect that such transfer does not require  registration of such
Securities under the Securities Act.

              (b) The Purchaser agrees to the imprinting, so long as is required
by this Section 4.1(b), of the following legend on certificates representing the
Securities:

         [NEITHER  THESE   SECURITIES  NOR  THE  SECURITIES   INTO  WHICH  THESE
    SECURITIES ARE  [CONVERTIBLE]  [EXERCISABLE]]  [THE  SECURITIES  REPRESENTED
    HEREBY]  HAVE  [NOT]  BEEN  REGISTERED  WITH  THE  SECURITIES  AND  EXCHANGE
    COMMISSION  OR THE  SECURITIES  COMMISSION  OF ANY STATE IN RELIANCE UPON AN
    EXEMPTION  FROM  REGISTRATION  UNDER THE  SECURITIES ACT OF 1933, AS AMENDED
    (THE "SECURITIES ACT"), AND, ACCORDINGLY,  MAY NOT BE OFFERED OR SOLD EXCEPT
    PURSUANT TO AN EFFECTIVE  REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR
    PURSUANT TO AN AVAILABLE  EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO
    THE REGISTRATION  REQUIREMENTS  THEREUNDER AND IN COMPLIANCE WITH APPLICABLE
    STATE SECURITIES OR BLUE SKY LAWS.

<PAGE>

         [FOR  SHARES  ONLY] THE  SHARES  REPRESENTED  BY THIS  CERTIFICATE  ARE
    SUBJECT TO CERTAIN  RESTRICTIONS  ON TRANSFER AND  CONVERSION SET FORTH IN A
    CONVERTIBLE  PREFERRED STOCK PURCHASE AGREEMENT,  DATED AS OF JUNE 25, 1997,
    BETWEEN VASOMEDICAL,  INC. (THE "COMPANY") AND THE ORIGINAL HOLDER HEREOF. A
    COPY OF THAT AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.

         The Underlying Shares issuable upon conversion of Shares or exercise of
the Warrant, as the case may be, shall not contain the legend set forth above if
the  conversion of Shares or exercise of the Warrant occurs at any time while an
Underlying Shares Registration  Statement is effective under the Securities Act,
or in the  event  there  is  not an  effective  Underlying  Shares  Registration
Statement at such time, if in the opinion of counsel to the Company  experienced
in the area of United States  securities  laws such legend is not required under
applicable    requirements   of   the   Securities   Act   (including   judicial
interpretations and pronouncements  issued by the staff of the Commission).  The
Company  agrees  that  it will  provide  the  Purchaser,  upon  request,  with a
certificate  or  certificates  representing  Underlying  Shares,  free from such
legend at such time as such legend is no longer required hereunder.

         Section 4.2.  Stop Transfer  Instruction.  The Company may not make any
notation  on its  records  or give  instructions  to any  transfer  agent of the
Company which enlarge the  restrictions  of transfer set forth in Section 4.1(b)
above.

         Section 4.3.  Furnishing of  Information.  For so long as the Purchaser
owns  Shares or  Underlying  Shares,  the Company  covenants  to timely file (or
obtain valid  extensions in respect thereof) all reports required to be filed by
the  Company  after the date hereof  pursuant  to Section  13(a) or 15(d) of the
Exchange Act and, if requested,  to promptly furnish the Purchaser with true and
complete  copies of all such filings.  Until such time as all Underlying  Shares
may be resold under Rule 144(k)  promulgated  under the  Securities  Act, if the
Company is not at the time required to file reports  pursuant to such  sections,
it will  prepare and furnish to the  Purchaser  annual and  quarterly  financial
statements, together with a discussion and analysis of such financial statements
in form and  substance  substantially  similar to those that would  otherwise be
required  to be included  in reports  required by Section  13(a) or 15(d) of the
Exchange  Act in the time period that such filings  would have been  required to
have been made under the Exchange Act.

         Section 4.4. Use of Disclosure  Materials.  The Company consents to the
use of the SEC Documents,  and any amendments and  supplements  thereto,  by the
Purchaser in  connection  with resales of  Securities  other than pursuant to an
effective registration statement.

<PAGE>

         Section 4.5.  Increase in  Authorized  Shares.  At any such time as the
Company  would be, if (with  respect to the  Shares) a notice of  conversion  or
(with  respect to the Warrant) form of election to purchase were to be delivered
on such date,  precluded  from  converting  at least 135% of the full  number of
Shares that remain  unconverted  or from  exercising  the entire Warrant at such
date (the "Overflow  Date"),  as the case may be, due to the  unavailability  of
authorized  but unissued or  re-acquired  Common Stock the Board of Directors of
the Company  shall  promptly  (and in any case within 14 Business Days from such
date) cause to be prepared and filed with the SEC and mailed to the shareholders
of the Company  within seven (7) Business Days after  clearance by the SEC or 15
days after  filing with the SEC in the event the SEC has not  commented  on such
filing,  proxy  materials  requesting   authorization  to  amend  the  Company's
certificate  of  incorporation  to increase the number of shares of Common Stock
which the Company is authorized to issue to at least  100,000,000 or to promptly
effect a reverse stock split so that it can satisfy its  conversion and exercise
obligations  in accordance  with the  Certificate  of  Designation  and Warrant,
provided, that if the Overflow Date occurs prior to the Company's annual meeting
of  shareholders  scheduled  to be held on or prior to November  30,  1997,  the
Company  shall make all requests and take all actions at such annual  meeting in
order to increase its  authorized  shares of Common Stock,  as set forth in this
Section 4.5. In connection  with an increase in the number of Shares,  the Board
of Directors shall (a) adopt proper resolutions  authorizing such increase,  (b)
recommend  to and  otherwise  use its best  efforts to promptly  and duly obtain
stockholder  approval to carry out such  resolutions (and hold a special meeting
of the  shareholders  no later  than the 40th day  after  mailing  of the  proxy
materials  relating to such meeting) and (c) within 5 Business Days of obtaining
such shareholder  authorization,  file an appropriate amendment to the Company's
certificate of incorporation to evidence such increase.

         Section 4.6. Blue Sky Laws. In accordance with the Registration  Rights
Agreement,  the Company shall qualify the Underlying Shares under the securities
or Blue Sky laws of such  jurisdictions as the Purchaser may reasonably  request
and continue such  qualification  at all times until the Purchaser  notifies the
Company in writing  that it no longer owns  Shares,  the  Warrant or  Underlying
Shares;  provided,  however, that neither the Company nor its Subsidiaries shall
be required in connection  therewith to qualify as a foreign  corporation  where
they are not now so qualified.

         Section 4.7. Integration.  The Company shall not and shall use its best
efforts to ensure that no Affiliate shall sell, offer for sale or solicit offers
to buy or otherwise  negotiate in respect of any security (as defined in Section
2 of the Securities  Act) that would be integrated with the offer or sale of the
Shares,  the Warrant or the Underlying Shares in a manner that would require the
registration  under the Securities Act of the sale of the Shares, the Warrant or
Underlying Shares to the Purchaser.

         Section  4.8.  Solicitation  Materials.   The  Company  shall  not  (i)
distribute  any offering  materials in connection  with the offering and sale of
the Shares, the Warrant or Underlying Shares other than the Disclosure Materials
and any amendments and supplements  thereto  prepared in compliance  herewith or
(ii)  solicit  any offer to buy or sell the Shares,  the  Warrant or  Underlying
Shares by means of any form of general solicitation or advertising.

<PAGE>

         Section 4.9. Right of First Refusal; Subsequent Registrations;  Certain
Corporate  Actions.  (a) The Company shall not, directly or indirectly,  without
the prior written  consent of the Purchaser,  offer,  sell,  grant any option to
purchase, or otherwise dispose (or announce any offer, sale, grant or any option
to  purchase or other  disposition)  of any of its or its  Affiliates  equity or
equity-equivalent  securities at a price which is on the face thereof or implied
therein,  less  than  either  the  market  price or fair  market  value for such
securities  (a  "Subsequent  Financing")  for a period of 180 days after Closing
Date, except (i) the granting of options or warrants to employees,  officers and
directors,  and the issuance of shares upon exercise of options  granted,  under
any stock option plan  heretofore  or  hereinafter  duly adopted by the Company,
(ii) shares issued upon exercise of any currently  outstanding warrants and upon
conversion of any currently outstanding convertible preferred stock in each case
disclosed  in  Schedule  3.1(c),  (iii)  shares  of  Common  Stock  issued  upon
conversion  of  Shares  in  accordance  with  the  terms of the  Certificate  of
Designation  and (iv)  sales of  Company  securities  not  exceeding  $1,000,000
(provided,  however, the Company may not sell such securities unless there are a
number of authorized and unreserved shares of Common Stock to permit the Company
to  legally  issue  200% of the  number of shares of Common  Stock that would be
issuable  in  respect of such  sale),  unless (A) the  Company  delivers  to the
Purchaser a written notice (the "Subsequent  Financing Notice") of its intention
to effect such Subsequent  Financing,  which  Subsequent  Financing Notice shall
describe in reasonable  detail the proposed terms of such Subsequent  Financing,
the amount of proceeds  intended to be raised  thereunder,  the Person with whom
such  Subsequent  Financing  shall be  affected,  and a term  sheet  or  similar
document relating thereto shall be attached to such Subsequent  Financing Notice
and (B) the Purchaser shall not have notified the Company by 5:00 p.m.  (Eastern
Time) on the fifth  Business Day after its receipt of the  Subsequent  Financing
Notice of its willingness to provide (or to cause its sole designee to provide),
subject to completion  of mutually  acceptable  documentation,  financing to the
Company on substantially the terms set forth in the Subsequent Financing Notice.
If the Purchaser shall fail to notify the Company of its intention to enter into
such negotiations within such time period, the Company may effect the Subsequent
Financing substantially upon the terms and to the Persons (or Affiliates of such
Persons)  set  forth in the  Subsequent  Financing  Notice;  provided,  that the
Company shall provide the Purchaser with a second  Subsequent  Financing Notice,
and the Purchaser shall again have the right of first refusal set forth above in
this  paragraph  (a),  if  the  Subsequent  Financing  subject  to  the  initial
Subsequent  Financing  Notice shall not have been  consummated for any reason on
the terms set forth in such Subsequent  Financing Notice within 60 Business Days
after the date of the initial Subsequent Financing Notice with the Person (or an
Affiliate of such Person) identified in the Subsequent Financing Notice.

         (b) Except  Underlying  Shares and other  "Registrable  Securities" (as
such term is defined in the Registration  Rights  Agreement) to be registered in
accordance with the Registration Rights Agreement, other than Company securities

<PAGE>

to be registered  under post  effective  amendments  of the  Company's  existing
registration  statements on Forms S-3, S-4 or S-8 (each as promulgated under the
Act) and other than Company securities to be registered for resale in connection
with financings permitted pursuant to Section 4.9(a)(i) through 4.9(a)(iv),  the
Company shall not, without the prior written consent of the Purchaser,  (i)issue
or  sell  any of its or any  of  its  Affiliates'  equity  or  equity-equivalent
securities  pursuant to Regulation S promulgated  under the  Securities  Act, or
(ii) register for resale any  securities of the Company for a period of not less
than 90 Trading  Days  after the date that the  Underlying  Shares  Registration
Statement is declared  effective by the Commission.  Any days that the Purchaser
is unable to sell  Underlying  Shares under the Underlying  Shares  Registration
Statement  shall be added to such 90 Trading Day period for the  purposes of (i)
and (ii) above.

         (c) As long as there are Shares outstanding,  the Company shall not and
shall cause the  Subsidiaries  not to, without the consent of the holders of the
Preferred  Stock,  (i) amend its certificate of  incorporation,  bylaws or other
charter documents so as to adversely affect any rights of the Purchaser,  except
the Company is permitted to increase authorized stock and/or engage in a reverse
stock split; (ii) repay,  repurchase or offer to repay,  repurchase or otherwise
acquire shares of its Common Stock other than as to the Underlying Shares except
under Company  option plans;  or (iii) enter into any agreement  with respect to
any of the foregoing.

         Section 4.10.  Purchaser  Ownership of Common Stock.  The Purchaser may
not use its  ability  to  convert  Shares  hereunder  or under  the terms of the
Certificate of Designation  to the extent that such  conversion  would result in
the Purchaser beneficially owning (for purposes of Rule 13d-3 under the Exchange
Act) more than 4.99% of the  outstanding  shares of the Common Stock;  provided,
however, that if ten days shall have elapsed since the Purchaser has declared an
event of default  under any  Transaction  Document and such event shall not have
been  cured to the  Purchaser's  satisfaction  prior to the  expiration  of such
ten-day  period,  the  provisions of this Section 4.10 shall be null and void ab
initio.

         Section 4.11.  Listing of Underlying  Shares. The Company shall (a) not
later than the tenth  Business Day following the Closing Date,  prepare and file
with The Nasdaq Sock Market,  Inc. (and each other national  securities exchange
or market on which the Common Stock is then listed) an additional shares listing
application  covering at least 6,683,464  Underlying  Shares, (b) take all steps
necessary to cause such shares to be approved for listing on such  exchanges and
markets  as soon  as  possible  thereafter,  and (c)  provide  to the  Purchaser
evidence of such filing and listing,  and the Company shall maintain the listing
of its Common Stock on such exchange.

         Section 4.12.  Certain  Redemption Events. (a) In the event that at any
time within the five-year period after the Closing Date trading in the shares of
the  Common  Stock is  suspended  on the  Nasdaq  SmallCap  Market  or any other
principal  market or  exchange  for such  shares  (other than as a result of the
suspension  of trading in  securities  on such market or exchange  generally  or
temporary suspensions pending the release of material information) for more than
three  Trading  Days  or  delisted  from  the  Nasdaq  SmallCap  Market,  unless

<PAGE>

immediately  therewith  the Common  Stock is listed for  trading on the New York
Stock Exchange,  the American Stock Exchange or the Nasdaq National  Market,  at
the  Purchaser's  option  exercisable  by five Business Days prior notice to the
Company,  the Company shall redeem all Shares and Underlying Shares then held by
the Purchaser, at an aggregate purchase price equal to the sum of (I) the number
of Shares then held by the  Purchaser  multiplied  by the product of (A) the Per
Share Market Value for the Trading Day immediately preceding (1) the day of such
notice or (2) the date of payment  in full of the  redemption  price  calculated
under this Section 4.12, whichever is greater,  multiplied by (B) the Conversion
Ratio on the date of such notice, (II) the number of Underlying Shares then held
by the  Purchaser  multiplied  by the Per Share Market Value for the Trading Day
immediately  preceding  (A) the date of the notice or (B) the date of payment in
full by the Company of the redemption  price calculated under this Section 4.12,
whichever is greater,  (III) the  aggregate of all accrued but unpaid  dividends
and other  amounts than due and payable on account of all Shares to be redeemed,
and (IV)  interest on the amounts set forth in I - III above  accruing  from the
5th day after such notice until the redemption  price under this Section 4.12 is
paid in full at the rate of 15% per annum (the "Redemption Price").

         (b) In the event the Underlying Shares Registration Statement shall not
have been  declared  effective  by the  Commission  on or prior to the 180th day
after the Closing Date,  then, at the  Purchaser's  option,  exercisable by five
Business  Days prior notice to the Company,  the Company shall redeem all Shares
and  Underlying  Shares  then  held by the  Purchaser  at a price  equal  to the
Redemption Price.

         (c) In the event  that any  conversion  of Shares  or  exercise  of the
Warrant  would,  if honored in full,  result in the  triggering of the Company's
Shareholder  Rights Plan as then in effect,  the Company  shall (i) timely honor
such conversion and/or exercise (as the case may be) and issue Underlying Shares
up to the maximum number,  and (ii) redeem all other Underlying  Shares that are
not delivered in respect of such  conversion or exercise at a price equal to the
Redemption  Price.  This  provision  shall apply to any  subsequent  conversions
and/or exercises.

         Section  4.13.  No Violation of  Applicable  Law.  Notwithstanding  any
provision of this  Agreement to the  contrary,  if any  redemption of Securities
otherwise  required under the  Transaction  Documents would be prohibited by the
relevant  provisions of the Delaware  General  Corporation  Law, such redemption
shall be effected as soon as it is permitted under such law; provided,  however,
that,  interest payable by the Company with respect to any such redemption shall
continue to accrue in accordance with Section 4.12 during any such period.

         Section 4.14. Redemption Restrictions. Notwithstanding any provision of
this  Agreement to the  contrary,  if any  redemption  of  Securities  otherwise
required under this Agreement would be prohibited in the absence of consent from
any lender of the Company or of any  Subsidiary,  or by the holders of any class
of securities  of the Company,  the Company shall use its best efforts to obtain

<PAGE>

such  consent as promptly  as  practicable  after the  redemption  is  required.
Interest  payable  by the  Company  with  respect to any such  redemption  shall
continue  to accrue in  accordance  with  Section  4.12  until  such  consent is
obtained.  Nothing  contained in this Section  shall be construed as a waiver by
the  Purchaser  of any  rights  it may  have  by  virtue  of any  breach  of any
representation  or  warranty  of the  Company  herein as to the  absence  of any
requirement to obtain any such consent.

         Section 4.15. Notice of Breaches. Each of the Company and the Purchaser
shall  give  prompt   written   notice  to  the  other  of  any  breach  of  any
representation,  warranty  or  other  agreement  contained  in  the  Transaction
Documents,  as well as any events or  occurrences  arising after the date hereof
and prior to the Closing  Date,  which could  reasonably  be likely to cause any
representation or warranty or other agreement of such party, as the case may be,
contained therein to be incorrect or breached as of such Closing Date.  However,
no disclosure  by either party  pursuant to this Section shall be deemed to cure
any breach of any such representation,  warranty or other agreement. Neither the
Company, any Subsidiary nor the Purchaser will take, or agree to commit to take,
any action  that is  intended  to make any  representation  or  warranty  of the
Company  or the  Purchaser,  as the case may be,  contained  in the  Transaction
Documents, inaccurate in any respect at the Closing Date.

         Notwithstanding  the  generality  of the  foregoing,  the Company shall
promptly  notify the Purchaser of any notice or claim  (written or oral) that it
receives from any lender of the Company to the effect that the  consummation  of
the transactions  contemplated by any of the Transaction  Documents  violates or
would violate any written agreement or understanding between such lender and the
Company,  and the Company shall promptly  furnish by facsimile to the holders of
the Shares a copy of any  written  statement  in support of or  relating to such
claim or notice.

         Section 4.16.  Conversion  Procedures.  Exhibit F attached  hereto sets
forth the procedures with respect to the conversion of the Shares, including the
forms of conversion  notice to be provided upon  conversion,  instructions as to
the procedures for  conversion,  the form of legal opinion,  if necessary,  that
shall  be  rendered  to the  Transfer  Agent  and  such  other  information  and
instructions as may be reasonably  necessary to enable the Purchaser to exercise
its right of conversion smoothly and expeditiously.

         Section 4.17.  Conversion and Exercise  Obligations of the Company. The
Company  covenants to honor  conversions of Shares and to honor  exercises under
the Warrant (as the case may be) to deliver Underlying Shares in accordance with
the terms and conditions  and time periods set forth in each of the  Certificate
of Designation and the Warrant.

         Section  4.18.  Transfer of  Intellectual  Property  Rights.  Except in
connection  with  the  sale of all or  substantially  all of the  assets  of the
Company that are covered under Section 5 of the Certificate of Designation,  the
Company  shall not  transfer,  sell or  otherwise  dispose of, any  Intellectual
Property Rights, or allow the Intellectual  Property Rights to become subject to
any Liens, without the prior written consent of the Purchaser.

Rights  Agreement and except that the Company  shall  reimburse the Purchaser at
the Closing $12,000 for its legal fees and  disbursements,  each party shall pay
the fees and expenses of its advisers,  counsel,  accountants and other experts,
if  any,  and  all  other  expenses  incurred  by  such  party  incident  to the

Shares) pursuant hereto.

with the Exhibits and Schedules  hereto,  the  Certificate of  Designation,  the
Warrant,  the  Registration  Rights Agreement and the Side Letter (together with
the respective Exhibits and Schedules thereto) contain the entire  understanding
of the parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, oral or written, with respect to such matters.

         Section 5.3.  Notices.  Any and all notices or other  communications or
deliveries  required or permitted to be provided  hereunder  shall be in writing

         Section 5.4. Amendments; Waivers. No provision of this Agreement may be
waived  or  amended  except in a written  instrument  signed,  in the case of an
amendment,  by both the Company and the Purchaser,  or, in the case of a waiver,
by the party against whom enforcement of any such waiver is sought. No waiver of
any default with respect to any  provision,  condition  or  requirement  of this
Agreement shall be deemed to be a continuing waiver in the future or a waiver of
any other  provision,  condition or requirement  hereof,  nor shall any delay or
omission of either  party to exercise any right  hereunder in any manner  impair
the exercise of any such right accruing to it thereafter.

        Section 5.5. Headings. The headings herein are for convenience only, do 
not constitute a part of this  Agreement  and shall not be deemed to limit or 
affect any of the provisions hereof.

         Section 5.6.  Successors and Assigns.  This Agreement  shall be binding
upon and inure to the benefit of the parties and their  successors and permitted

<PAGE>

assigns.  Neither the Company nor the Purchaser may assign this Agreement or any
rights or obligations  hereunder without the prior written consent of the other,
except that the Purchaser may assign its rights  hereunder and under the Warrant
and the  Registration  Rights  Agreement  without  the  consent of the  Company,
provided,  that the Company shall have the right to require any such assignee to
execute a counterpart of this Agreement and any other  Transaction  Documents to
which the assignor was a party as a condition to such holders claim to any right
hereunder or  thereunder.  The  assignment  by a party of this  Agreement or any
rights  hereunder  shall not affect  the  obligations  of such party  under this
Agreement.

         Section 5.7. No Third-Party  Beneficiaries.  This Agreement is intended
for the benefit of the parties hereto and their respective  permitted successors
and assigns and,  other than with respect to permitted  assignees  under Section
5.6, is not for the benefit of, nor may any provision hereof be enforced by, any
other person.

         Section 5.8.  Governing  Law. This  Agreement  shall be governed by and
construed and enforced in accordance  with the internal laws of the State of New
York without regard to the principles of conflicts of law thereof.

         Section  5.9.  Survival.  The  representations  and  warranties  of the
Company  and the  Purchaser  contained  in Article  III and the  agreements  and
covenants  of the  parties  contained  in  Article  IV and this  Article V shall
survive  the  Closing (or any earlier  termination  of this  Agreement)  and any
conversion of Shares and exercise of the Warrant.

         Section 5.10. Counterpart Signatures. This Agreement may be executed in
two or more  counterparts,  all of which when taken together shall be considered
one and the same  agreement and shall become  effective when  counterparts  have
been signed by each party and delivered to the other party, it being  understood
that both  parties  need not sign the same  counterpart.  In the event  that any
signature is delivered by facsimile transmission,  such signature shall create a
valid and binding  obligation  of the party  executing  (or on whose behalf such
signature  is  executed)  the same  with the same  force  and  effect as if such
facsimile signature page were an original thereof.

         Section 5.11.  Publicity.  The Company and the Purchaser  shall consult
with each  other in  issuing  any press  releases  or  otherwise  making  public
statements  with  respect to the  transactions  contemplated  hereby and neither
party  shall  issue any such press  release or  otherwise  make any such  public
statement  without the prior written  consent of the other,  which consent shall
not be unreasonably  withheld or delayed,  except that no prior consent shall be
required  if such  disclosure  is  required  by law,  in  which  such  case  the
disclosing  party shall provide the other party with prior notice of such public
statement.

         Section 5.12.  Severability.  In case any one or more of the provisions
of this Agreement shall be invalid or unenforceable in any respect, the validity
and enforceability of the remaining terms and provisions of this Agreement shall
not in any way be affecting or impaired  thereby and the parties will attempt to
agree  upon a valid  and  enforceable  provision  which  shall  be a  reasonable
substitute  therefor,  and upon so agreeing,  shall  incorporate such substitute
provision in this Agreement.

<PAGE>

         Section 5.13.  Remedies.  In addition to being entitled to exercise all
rights provided  herein or granted by law,  including  recovery of damages,  the
Purchaser  will be entitled to specific  performance  of the  obligations of the
Company  under this  Agreement  and the  Company  will be  entitled  to specific
performance of the  obligations  of the Purchaser  hereunder with respect to the
subsequent transfer of Shares and the Underlying Shares. Each of the Company and
the Purchaser  agrees that monetary  damages would not be adequate  compensation
for any loss  incurred by reason of any breach of its  obligations  described in
the  foregoing  sentence  and hereby  agrees to waive in any action for specific
performance  of any such  obligation  the defense  that a remedy at law would be
adequate.

                          REGISTRATION RIGHTS AGREEMENT

substantially the same effect as such Rule.

          "Rule 158" means Rule 158  promulgated by the  Commission  pursuant to
the  Securities  Act,  as such Rule may be  amended  from  time to time,  or any
similar  rule  or  regulation   hereafter   adopted  by  the  Commission  having
substantially the same effect as such Rule.

          "Rule 415" means Rule 415  promulgated by the  Commission  pursuant to
the  Securities  Act,  as such Rule may be  amended  from  time to time,  or any
similar  rule  or  regulation   hereafter   adopted  by  the  Commission  having

     2.   Shelf Registration

          (a) On or prior to the Filing Date, the Company shall prepare and file
with the Commission a "Shelf"  Registration  Statement  covering all Registrable
Securities  for an offering to be made on a  continuous  basis  pursuant to Rule
415.  The  Registration  Statement  shall be on Form S-3  (except  if  otherwise
directed  by the Holders in  accordance  herewith).  The  Company  shall (i) not
permit any securities  other than the  Registrable  Securities to be included in
the Registration  Statement  (except as permitted  pursuant to Section 7(c)) and
(ii) use its best  efforts to cause the  Registration  Statement  to be declared
effective  under the  Securities  Act as promptly  as possible  after the filing
thereof,  but in any event  prior to the  Effectiveness  Date,  and to keep such
Registration Statement continuously effective under the Securities Act until the
date which is three years  after the date that such  Registration  Statement  is
declared  effective by the Commission or such earlier date when all  Registrable
Securities covered by such Registration  Statement have been sold or may be sold
without volume restrictions pursuant to Rule 144 as determined by the counsel to
the Company  pursuant to a written opinion letter  reasonably  acceptable to the
Holders  and  addressed  to the  Holders  to  such  effect  (the  "Effectiveness
Period");  provided,  however, that the Company shall not be deemed to have used
its best  efforts  to keep  the  Registration  Statement  effective  during  the
Effectiveness Period if it voluntarily takes any action that would result in the
Holders  not  being  able to sell the  Registrable  Securities  covered  by such
Registration  Statement during the Effectiveness  Period,  unless such action is
required under  applicable law or the Company promptly files after such action a
post-effective  amendment to the  Registration  Statement and the Commission has
not declared it effective.

          (b) If the  Holders of a majority  of the  Registrable  Securities  so
elect,  an  offering of  Registrable  Securities  pursuant  to the  Registration
Statement  may be  effected  in the form of an  Underwritten  Offering.  In such
event, and if the managing  underwriters  advise the Company and such Holders in
writing that in their opinion the amount of Registrable  Securities  proposed to
be sold  in  such  Underwritten  Offering  exceeds  the  amount  of  Registrable
Securities  which  can be sold in such  Underwritten  Offering,  there  shall be
included in such Underwritten Offering the amount of such Registrable Securities
which in the opinion of such managing  underwriters can be sold, and such amount
shall be  allocated  pro rata among the Holders  proposing  to sell  Registrable
Securities in such Underwritten Offering.

          (c) If  any  of  the  Registrable  Securities  are  to be  sold  in an
Underwritten  Offering,  the investment banker or investment bankers and manager
or managers that will  administer the offering will be reputable firms that will
be selected by the Holders of a majority of the Registrable  Securities included
in such offering  upon  consultation  with (but not consent of) the Company.  No
Holder may participate in any Underwritten Offering hereunder unless such Person
(i)  agrees to sell its  Registrable  Securities  on the basis  provided  in any
underwriting  agreements  approved by the Persons entitled  hereunder to approve
such arrangements and (ii) completes and executes all questionnaires,  powers of
attorney,  indemnities,  underwriting  agreements and other  documents  required
under the terms of such arrangements.

     3.   Registration Procedures

          In connection with the Company's  registration  obligations hereunder,
the Company shall:

          (a)  Prepare  and file with the  Commission  on or prior to the Filing
Date a  Registration  Statement  on Form S-3 in  accordance  with the  method or
methods of distribution thereof as specified by the Holders (except if otherwise
directed  by the  Holders),  and  cause  the  Registration  Statement  to become
effective and remain effective as provided herein;  provided,  however, that not
less than  three  (3)  Business  Days  prior to the  filing of the  Registration
Statement  or any related  Prospectus  or any  amendment or  supplement  thereto
(including any document that would be  incorporated or deemed to be incorporated
therein by  reference),  the  Company  shall (i) furnish to the  Holders,  their
Special  Counsel and any  managing  underwriters,  copies of all such  documents
proposed to be filed,  which documents (other than those  incorporated or deemed
to be  incorporated by reference) will be subject to the review of such Holders,
their  Special  Counsel  and such  managing  underwriters,  and (ii)  cause  its
officers and directors,  counsel and independent certified public accountants to
respond to such  inquiries as shall be  necessary,  in the opinion of respective
counsel  to  such  Holders  and  such  underwriters,  to  conduct  a  reasonable
investigation  within the meaning of the  Securities  Act. The Company shall not
file the  Registration  Statement or any such  Prospectus  or any  amendments or
supplements  thereto  to which the  Holders  of a  majority  of the  Registrable
Securities,   their  Special  Counsel,  or  any  managing  underwriters,   shall
reasonably object on a timely basis.

          (b)  (i)  Prepare  and  file  with  the  Commission  such  amendments,
including  post-effective  amendments,  to the Registration  Statement as may be
necessary to keep the Registration  Statement  continuously  effective as to all
Registrable  Securities for the applicable time period and prepare and file with
the Commission such additional  Registration Statements in order to register for
resale under the Securities Act all of the  Registrable  Securities;  (ii) cause
the related Prospectus to be amended or supplemented by any required  Prospectus
supplement,  and as so  supplemented or amended to be filed pursuant to Rule 424
(or any similar  provisions then in force) promulgated under the Securities Act;
(iii)  respond as promptly as  practicable  to any  comments  received  from the
Commission with respect to the Registration  Statement or any amendment  thereto
and promptly provide the Holders true and complete copies of all  correspondence
from and to the  Commission  relating to the  Registration  Statement;  and (iv)
comply with the  provisions  of the  Securities  Act and the  Exchange  Act with
respect  to  the  disposition  of  all  Registrable  Securities  covered  by the
Registration  Statement  during the  applicable  period in  accordance  with the
intended  methods  of  disposition  by the  Holders  thereof  set  forth  in the
Registration Statement as so amended or in such Prospectus as so supplemented.

          (c) Notify the Holders of  Registrable  Securities  to be sold,  their
Special Counsel and any managing  underwriters  immediately (and, in the case of
(i)(A)  below,  not less  than  three  (3) days  prior to such  filing)  and (if
requested by any such  Person)  confirm such notice in writing no later than one
(1) Business Day following  the day (i)(A) when a Prospectus  or any  Prospectus
supplement or post-effective amendment to the Registration Statement is proposed
to be filed; (B) when the Commission  notifies the Company whether there will be
a "review" of such Registration  Statement and whenever the Commission  comments
in writing on such  Registration  Statement  (the Company shall provide true and
complete  copies  thereof to each of the Holders upon request  therefor) and (C)
with respect to the Registration Statement or any post-effective amendment, when

<PAGE>

the same has become  effective;  (ii) of any  request by the  Commission  or any
other Federal or state  governmental  authority for amendments or supplements to
the Registration Statement or Prospectus or for additional information; (iii) of
the issuance by the Commission of any stop order suspending the effectiveness of
the Registration  Statement covering any or all of the Registrable Securities or
the initiation of any Proceedings  for that purpose;  (iv) if at any time any of
the  representations  and  warranties of the Company  contained in any agreement
(including any underwriting agreement) contemplated hereby ceases to be true and
correct in all  material  respects;  (v) of the  receipt  by the  Company of any
notification  with respect to the suspension of the  qualification  or exemption
from  qualification  of  any of  the  Registrable  Securities  for  sale  in any
jurisdiction,  or the  initiation  or  threatening  of any  Proceeding  for such
purpose;  and (vi) of the  occurrence of any event that makes any statement made
in the  Registration  Statement or  Prospectus or any document  incorporated  or
deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration  Statement,  Prospectus or other
documents so that, in the case of the Registration  Statement or the Prospectus,
as the case may be, it will not contain any untrue  statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

          (d) Use its best  efforts  to avoid the  issuance  of,  or, if issued,
obtain the  withdrawal  of (i) any order  suspending  the  effectiveness  of the
Registration Statement or (ii) any suspension of the qualification (or exemption
from  qualification)  of any of  the  Registrable  Securities  for  sale  in any
jurisdiction, at the earliest practicable moment.

          (e) If  requested  by any  managing  underwriter  or the  Holders of a
majority  of the  Registrable  Securities  to be  sold  in  connection  with  an
Underwritten  Offering,  (i) promptly incorporate in a Prospectus  supplement or
post-effective  amendment to the Registration Statement such information as such
managing  underwriters  and such  Holders  reasonably  agree  should be included

<PAGE>

therein and (ii) make all required filings of such Prospectus supplement or such
post-effective  amendment as soon as practicable  after the Company has received
notification of the matters to be incorporated in such Prospectus  supplement or
post-effective  amendment;  provided,  however,  that the  Company  shall not be
required to take any action  pursuant to this  Section  3(e) that would,  in the
opinion of counsel for the Company, violate applicable law.

          (f) Furnish to each  Holder,  their  Special  Counsel and any managing
underwriters,  without charge,  at least one conformed copy of each Registration
Statement  and  each  amendment  thereto,  including  financial  statements  and
schedules,  all documents  incorporated or deemed to be incorporated  therein by
reference,  and all exhibits to the extent  requested by such Person  (including
those  previously  furnished or  incorporated  by reference)  promptly after the
filing of such documents with the Commission.

          (g) Promptly deliver to each Holder,  their Special  Counsel,  and any
underwriters,  without charge,  as many copies of the Prospectus or Prospectuses
(including each form of prospectus) and each amendment or supplement  thereto as
such Persons may reasonably request;  and the Company hereby consents to the use
of such  Prospectus  and each  amendment  or  supplement  thereto by each of the
selling Holders and any underwriters in connection with the offering and sale of
the  Registrable  Securities  covered by such  Prospectus  and any  amendment or
supplement thereto.

          (h) Prior to any public  offering of Registrable  Securities,  use its
best efforts to register or qualify or cooperate with the selling  Holders,  any
underwriters and their respective counsel in connection with the registration or
qualification  (or exemption from such  registration or  qualification)  of such
Registrable  Securities for offer and sale under the securities or Blue Sky laws
of such  jurisdictions  within  the United  States as any Holder or  underwriter
reasonably  requests in writing, to keep each such registration or qualification
(or exemption therefrom) effective during the Effectiveness Period and to do any
and all other acts or things necessary or advisable to enable the disposition in
such  jurisdictions  of the  Registrable  Securities  covered by a  Registration
Statement;  provided, however, that the Company shall not be required to qualify
generally to do business in any  jurisdiction  where it is not then so qualified
or to take any action that would subject it to general service of process in any
such jurisdiction  where it is not then so subject or subject the Company to any
material tax in any such jurisdiction where it is not then so subject.

          (i)  Cooperate  with the  Holders  and any  managing  underwriters  to
facilitate  the timely  preparation  and delivery of  certificates  representing
Registrable  Securities  to be  sold,  which  certificates  shall be free of all
restrictive  legends,  and to enable such  Registrable  Securities to be in such
denominations and registered in such names as any such managing  underwriters or
Holders may request at least two Business Days prior to any sale of  Registrable
Securities.
<PAGE>

          (j) Upon the occurrence of any event contemplated by Section 3(c)(vi),
as promptly as  practicable,  prepare a  supplement  or  amendment,  including a
post-effective  amendment,  to the Registration Statement or a supplement to the
related  Prospectus or any document  incorporated  or deemed to be  incorporated
therein  by  reference,  and file  any  other  required  document  so  that,  as
thereafter  delivered,  neither the  Registration  Statement nor such Prospectus
will contain an untrue  statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements  therein,
in light of the circumstances under which they were made, not misleading.

          (k) Use its best efforts to cause all Registrable  Securities relating
to such  Registration  Statement to be listed on the Nasdaq  SmallCap Market and
any other securities  exchange,  quotation  system,  market or  over-the-counter
bulletin  board, if any, on which similar  securities  issued by the Company are
then listed.

          (l) Enter into such agreements (including an underwriting agreement in
form,  scope and substance as is customary in  Underwritten  Offerings) and take
all such other  actions in  connection  therewith  (including  those  reasonably
requested  by any  managing  underwriters  and the  Holders of a majority of the
Registrable  Securities  being  sold) in order to  expedite  or  facilitate  the
disposition of such Registrable  Securities,  and whether or not an underwriting
agreement is entered into, (i) make such  representations and warranties to such
Holders and such underwriters as are customarily made by issuers to underwriters
in underwritten  public  offerings,  and confirm the same if and when requested;
(ii)  obtain  and  deliver  copies  thereof  to each  Holder  and  the  managing
underwriters,  if any, of opinions of counsel to the Company and updates thereof
addressed to each selling Holder and each such  underwriter,  in form, scope and
substance reasonably  satisfactory to any such managing underwriters and Special
Counsel to the  selling  Holders  covering  the matters  customarily  covered in
opinions  requested in  Underwritten  Offerings and such other matters as may be
reasonably requested by such Special Counsel and underwriters; (iii) immediately
prior to the effectiveness of the Registration Statement, and, in the case of an
Underwritten  Offering,  at the time of delivery of any  Registrable  Securities
sold pursuant thereto, obtain and deliver copies to the Holders and the managing
underwriters,  if any, of "cold  comfort"  letters and updates  thereof from the
independent certified public accountants of the Company (and, if necessary,  any
other independent  certified public accountants of any subsidiary of the Company
or of any business  acquired by the Company for which  financial  statements and
financial  data  is,  or  is  required  to  be,  included  in  the  Registration
Statement),  addressed to each selling Holder and each of the  underwriters,  if
any, in form and  substance as are  customary in  connection  with  Underwritten
Offerings;  (iv) if an  underwriting  agreement is entered into,  the same shall
contain  indemnification  provisions  and  procedures  no less  favorable to the
selling Holders and the underwriters,  if any, than those set forth in Section 6
(or  such  other   provisions   and   procedures   acceptable  to  the  managing
underwriters,  if any,  and  holders of a  majority  of  Registrable  Securities
participating in such Underwritten  Offering; and (v) deliver such documents and
certificates as may be reasonably  requested by the Holders of a majority of the
Registrable  Securities  being sold,  their  Special  Counsel  and any  managing
underwriters  to evidence  the  continued  validity of the  representations  and
warranties made pursuant to clause 3(l)(i) above and to evidence compliance with
any  customary  conditions  contained  in the  underwriting  agreement  or other
agreement entered into by the Company.

<PAGE>

          (m)  Make  available  for  inspection  by  the  selling  Holders,  any
representative of such Holders, any underwriter participating in any disposition
of  Registrable  Securities,  and any  attorney or  accountant  retained by such
selling  Holders or  underwriters,  at the offices where normally  kept,  during
reasonable business hours, all financial and other records,  pertinent corporate
documents  and  properties  of the Company and its  subsidiaries,  and cause the
officers, directors, agents and employees of the Company and its subsidiaries to
supply  all   information   in  each  case   requested   by  any  such   Holder,
representative,  underwriter,  attorney or  accountant  in  connection  with the
Registration  Statement  as shall be  reasonably  necessary  to  enable  them to
exercise  their  due  diligence  responsibility;  provided,  however,  that  any
information  that is determined in good faith by the Company in writing to be of
a confidential  nature at the time of delivery of such information shall be kept
confidential  by such  Persons,  unless (i)  disclosure of such  information  is
required  by court  or  administrative  order  or is  necessary  to  respond  to
inquiries of regulatory authorities; (ii) disclosure of such information, in the
opinion of counsel to such Person,  is required by law;  (iii) such  information
becomes generally available to the public other than as a result of a disclosure
or  failure  to  safeguard  by such  Person;  or (iv) such  information  becomes
available to such Person from a source other than the Company and such source is
not known by such  Person to be bound by a  confidentiality  agreement  with the
Company.

          (n) Comply with all applicable rules and regulations of the Commission
and  make  generally  available  to  its  security  holders  earning  statements
satisfying  the  provisions of Section 11(a) of the  Securities Act and Rule 158
not later  than 45 days after the end of any  12-month  period (or 90 days after
the end of any 12-month  period if such period is a fiscal year) (i)  commencing
at the end of any fiscal  quarter in which  Registrable  Securities  are sold to
underwriters in a firm commitment or best efforts Underwritten Offering and (ii)
if not sold to underwriters in such an offering,  commencing on the first day of
the  first  fiscal  quarter  of the  Company  after  the  effective  date of the
Registration Statement, which statement shall cover said 12-month period, or end
shorter periods as is consistent with the requirements of Rule 158.

          The Company may require each selling  Holder to furnish to the Company
such information regarding the distribution of such Registrable Securities as is
required by law to be disclosed in the  Registration  Statement  and the Company
may exclude from such registration the Registrable Securities of any such Holder
who  unreasonably  fails to furnish such  information  within a reasonable  time
after receiving such request.

          If  the  Registration  Statement  refers  to any  Holder  by  name  or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (i) the  inclusion  therein of  language,  in form and

<PAGE>

substance  reasonably  satisfactory  to such  Holder,  to the  effect  that  the
ownership  by  such  Holder  of  such  securities  is not to be  construed  as a
recommendation  by  such  Holder  of the  investment  quality  of the  Company's
securities  covered  thereby  and that such  ownership  does not imply that such
Holder will assist in meeting any future financial  requirements of the Company,
or (ii) if such reference to such Holder by name or otherwise is not required by
the Securities Act or any similar Federal statute then in force, the deletion of
the reference to such Holder in any amendment or supplement to the  Registration
Statement filed or prepared subsequent to the time that such reference ceases to
be required.

          Each Purchaser covenants and agrees that (i) it will not offer or sell
any  Registrable  Securities  under  the  Registration  Statement  until  it has
received   copies  of  the  Prospectus  as  then  amended  or   supplemented  as
contemplated in Section 3(g) and notice from the Company that such  Registration
Statement and any  post-effective  amendments  thereto have become  effective as
contemplated by Section 3(c) and (ii) the Purchaser and its officers,  directors
or Affiliates,  if any, will comply with the prospectus delivery requirements of
the Securities Act as applicable to them in connection with sales of Registrable
Securities pursuant to the Registration Statement.

          Each Holder agrees by its acquisition of such  Registrable  Securities
that,  upon receipt of a notice from the Company of the  occurrence of any event
of the kind  described  in Section  3(c)(ii),  3(c)(iii),  3(c)(iv),  3(c)(v) or
3(c)(vi), such Holder will forthwith discontinue disposition of such Registrable
Securities  until  such  Holder's  receipt  of the  copies  of the  supplemented
Prospectus and/or amended Registration  Statement  contemplated by Section 3(j),
or until it is advised in writing (the  "Advice") by the Company that the use of
the  applicable  Prospectus  may be resumed,  and, in either case,  has received
copies of any additional or supplemental filings that are incorporated or deemed
to be incorporated by reference in such Prospectus or Registration Statement.

          4.   Registration Expenses

          (a) All fees and expenses incident to the performance of or compliance
with this Agreement by the Company shall be borne by the Company  whether or not
the Registration  Statement is filed or becomes effective and whether or not any
Registrable Securities are sold pursuant to the Registration Statement. The fees
and  expenses  referred to in the  foregoing  sentence  shall  include,  without
limitation, (i) all registration and filing fees (including, without limitation,
fees and  expenses  (A) with  respect  to filings  required  to be made with the
National  Association  of Securities  Dealers,  Inc. and (B) in compliance  with
state  securities  or Blue Sky laws  (including,  without  limitation,  fees and

<PAGE>

disbursements of counsel for the underwriters or Holders in connection with Blue
Sky  qualifications  of the  Registrable  Securities  and  determination  of the
eligibility of the Registrable  Securities for investment under the laws of such
jurisdictions as the managing underwriters,  if any, or Holders of a majority of
Registrable  Securities  may  designate)),  (ii) printing  expenses  (including,
without limitation, expenses of printing certificates for Registrable Securities
and of printing prospectuses if the printing of prospectuses is requested by the
managing  underwriters,  if  any,  or  by  the  holders  of a  majority  of  the
Registrable Securities included in the Registration Statement), (iii) messenger,
telephone and delivery expenses,  (iv) fees and disbursements of counsel for the
Company,  (v)  fees  and  disbursements  of  all  independent  certified  public
accountants referred to in Section 3(1)(iii) (including, without limitation, the
expenses of any special audit and "cold comfort" letters required by or incident
to such performance), (vi) Securities Act liability insurance, if the Company so
desires  such  insurance,  and (vii)  fees and  expenses  of all  other  Persons
retained by the Company in connection with the  consummation of the transactions
contemplated  by this Agreement.  In addition,  the Company shall be responsible
for all of its internal expenses incurred in connection with the consummation of
the transactions contemplated by this Agreement (including,  without limitation,
all salaries and expenses of its  officers  and  employees  performing  legal or
accounting  duties),  the  expense of any annual  audit,  the fees and  expenses
incurred in  connection  with the listing of the  Registrable  Securities on any
securities  exchange on which similar  securities issued by the Company are then
listed.

          (b) If the Holders  require an Underwritten  Offering  pursuant to the
terms hereof,  the Company shall be responsible for all costs, fees and expenses
in  connection  therewith,   except  for  the  fees  and  disbursements  of  the
Underwriters  (including any  underwriting  commissions and discounts) and their
legal counsel and accountants (which shall be borne by the Holders).  Therefore,
in such  circumstances  the  Holder  shall  bear  the  expenses  of the fees and
disbursements   of  any  legal  counsel  or  accounting  firm  retained  by  the
underwriters in connection with such Underwritten  Offering and the costs of any
determination  (but not filing) by the  underwriters  of the  eligibility of the
Registrable  Securities for investment  under the  applicable  state  securities
laws.  By way of  illustration  which is not  intended  to  diminish  any of the
provisions  hereof,  the Holders shall not be  responsible  for, and the Company
shall be  required  to pay the fees or  disbursements  incurred  by the  Company
(including  by its legal  counsel  and  accountants)  in  connection  with,  the
preparation  and filing of a Registration  Statement and related  Prospectus for
such offering, the maintenance of such Registration Statement in accordance with
the terms hereof,  the listing of the Registrable  Securities in accordance with
the  requirements  hereof,  and  printing  expenses  incurred to comply with the
requirements hereof.


     5.1  Indemnification

          (a) Indemnification by the Company. The Company shall, notwithstanding
any termination of this Agreement and without  limitation as to time,  indemnify
and hold harmless each Holder,  the officers,  directors,  agents (including any
underwriters  retained by such Holder in  connection  with the offer and sale of
Registrable   Securities),   brokers  (including  brokers  who  offer  and  sell
Registrable  Securities  as  principal as a result of a pledge or any failure to

<PAGE>

perform under a margin call of Common Stock),  investment advisors and employees
of each of them, each Person who controls any such Holder (within the meaning of
Section 15 of the  Securities  Act or Section  20 of the  Exchange  Act) and the
officers,  directors,  agents and employees of each such controlling  Person, to
the fullest  extent  permitted by  applicable  law, from and against any and all
losses,  claims,  damages,  liabilities,  costs (including,  without limitation,
reasonable  costs of preparation  and reasonable  attorneys'  fees) and expenses
(collectively,  "Losses"), as incurred, arising out of or relating to any untrue
or alleged  untrue  statement of a material fact  contained in the  Registration
Statement,  any  Prospectus  or any form of  prospectus  or in any  amendment or
supplement  thereto  or in any  preliminary  prospectus,  or  arising  out of or
relating to any omission or alleged  omission of a material  fact required to be
stated therein or necessary to make the  statements  therein (in the case of any
Prospectus  or form  of  prospectus  or  supplement  thereto,  in  light  of the
circumstances under which they were made) not misleading,  except to the extent,
but only to the  extent,  that such untrue  statements  or  omissions  are based
solely  upon  information  regarding  such  Holder  furnished  in writing to the
Company  by or on  behalf  of  such  Holder  expressly  for use  therein,  which
information  was  reasonably  relied on by the Company for use therein or to the
extent that such  information  relates to such Holder or such Holder's  proposed
method of distribution of Registrable  Securities and was reviewed and expressly
approved  in  writing  by such  Holder  expressly  for  use in the  Registration
Statement,  such  Prospectus  or such form of  Prospectus or in any amendment or
supplement  thereto.  The  Company  shall  notify the  Holders  promptly  of the
institution, threat or assertion of any Proceeding of which the Company is aware
in connection with the transactions contemplated by this Agreement.

          (b) Indemnification by Holders.  Each Holder shall,  severally and not
jointly,  indemnify and hold harmless the Company,  their  directors,  officers,
agents and employees,  each Person who controls the Company  (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors,  officers,  agents or employees of such controlling  Persons,  to the
fullest  extent  permitted by  applicable  law,  from and against all Losses (as
determined by a court of competent  jurisdiction in a final judgment not subject
to appeal or  review)  arising  solely  out of or based  solely  upon any untrue
statement  of a material  fact  contained  in the  Registration  Statement,  any
Prospectus,  or any form of prospectus, or arising solely out of or based solely
upon any omission of a material fact required to be stated  therein or necessary
to make the  statements  therein not  misleading to the extent,  but only to the
extent,  that such untrue  statement or omission is contained in any information
so furnished in writing by such Holder to the Company specifically for inclusion
in the  Registration  Statement or such Prospectus and that such information was
reasonably  relied upon by the Company  for use in the  Registration  Statement,
such  Prospectus  or  such  form  of  prospectus  or to  the  extent  that  such
information  relates  to  such  Holder  or  such  Holder's  proposed  method  of
distribution of Registrable  Securities and was reviewed and expressly  approved
in writing by such Holder expressly for use in the Registration Statement,  such
Prospectus  or such form of  Prospectus.  In no event shall the liability of any
selling Holder  hereunder be greater in amount than the dollar amount of the net
proceeds  received by such Holder  upon the sale of the  Registrable  Securities
giving rise to such indemnification obligation.

<PAGE>

          (c) Conduct of Indemnification Proceedings. If any Proceeding shall be
brought or asserted  against  any Person  entitled to  indemnity  hereunder  (an
"Indemnified  Party"),  such Indemnified  Party promptly shall notify the Person
from whom  indemnity is sought (the  "Indemnifying  Party") in writing,  and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably  satisfactory to the Indemnified Party and the payment of all
fees and expenses  incurred in connection with defense thereof;  provided,  that
the failure of any  Indemnified  Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally  determined  by a court
of  competent  jurisdiction  (which  determination  is not  subject to appeal or
further  review)  that  such  failure  shall  have  proximately  and  materially
adversely prejudiced the Indemnifying Party.

          An Indemnified  Party shall have the right to employ separate  counsel
in any such Proceeding and to participate in the defense  thereof,  but the fees
and expenses of such counsel shall be at the expense of such  Indemnified  Party
or Parties unless:  (1) the  Indemnifying  Party has agreed to pay such fees and
expenses; or (2) the Indemnifying Party shall have failed promptly to assume the
defense of such Proceeding and to employ counsel reasonably satisfactory to such
Indemnified  Party in any such Proceeding;  or (3) the named parties to any such
Proceeding (including any impleaded parties) include both such Indemnified Party
and the Indemnifying  Party, and such Indemnified  Party shall have been advised
by counsel  that a conflict of  interest is likely to exist if the same  counsel
were to represent such Indemnified  Party and the  Indemnifying  Party (in which
case, if such Indemnified Party notifies the Indemnifying  Party in writing that
it elects to employ separate counsel at the expense of the  Indemnifying  Party,
the  Indemnifying  Party shall not have the right to assume the defense  thereof
and such  counsel  shall  be at the  expense  of the  Indemnifying  Party).  The
Indemnifying Party shall not be liable for any settlement of any such Proceeding
effected  without its written  consent,  which consent shall not be unreasonably
withheld.  No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any settlement of any pending Proceeding in respect of
which any  Indemnified  Party is a party,  unless  such  settlement  includes an
unconditional  release of such  Indemnified  Party from all  liability on claims
that are the subject matter of such Proceeding.

          All fees and expenses of the Indemnified  Party (including  reasonable
fees and expenses to the extent  incurred in connection  with  investigating  or
preparing  to defend  such  Proceeding  in a manner not  inconsistent  with this
Section) shall be paid to the Indemnified Party, as incurred, within 10 Business
Days of written notice thereof to the Indemnifying  Party (regardless of whether
it is  ultimately  determined  that an  Indemnified  Party  is not  entitled  to
indemnification  hereunder;  provided,  that the Indemnifying  Party may require
such  Indemnified  Party to undertake to reimburse all such fees and expenses to
the extent it is finally  judicially  determined that such Indemnified  Party is
not entitled to indemnification hereunder).

<PAGE>

          (d) Contribution. If a claim for indemnification under Section 5(a) or
5(b) is  unavailable  to an Indemnified  Party or is  insufficient  to hold such
Indemnified Party harmless for any Losses in respect of which this Section would
apply  by its  terms  (other  than by  reason  of  exceptions  provided  in this
Section), then each Indemnifying Party, in lieu of indemnifying such Indemnified
Party,  shall contribute to the amount paid or payable by such Indemnified Party
as a result of such Losses,  in such proportion as is appropriate to reflect the
relative fault of the  Indemnifying  Party and  Indemnified  Party in connection
with the actions,  statements or omissions  that resulted in such Losses as well
as any other  relevant  equitable  considerations.  The  relative  fault of such
Indemnifying  Party and  Indemnified  Party shall be determined by reference to,
among other  things,  whether any action in  question,  including  any untrue or
alleged untrue statement of a material fact or omission or alleged omission of a
material fact, has been taken or made by, or relates to information supplied by,
such Indemnifying  Party or Indemnified Party, and the parties' relative intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include,  subject to the  limitations set forth
in Section 5(c), any attorneys' or other fees or expenses incurred by such party
in  connection  with any  Proceeding  to the extent  such party  would have been
indemnified  for such fees or expenses if the  indemnification  provided  for in
this Section was available to such party.

          The parties  hereto  agree that it would not be just and  equitable if
contribution  pursuant  to  this  Section  5(d)  were  determined  by  pro  rata
allocation or by any other method of allocation  that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding  the provisions of this Section 5(d), the Purchaser shall not be
required to contribute,  in the aggregate, any amount in excess of the amount by
which the  proceeds  actually  received  by the  Purchaser  from the sale of the
Registrable  Securities  subject  to the  Proceeding  exceeds  the amount of any
damages that the Purchaser has otherwise  been required to pay by reason of such
untrue or alleged untrue  statement or omission or alleged  omission.  No Person
guilty of fraudulent  misrepresentation  (within the meaning of Section 11(f) of
the Securities  Act) shall be entitled to  contribution  from any Person who was
not guilty of such fraudulent misrepresentation.

          The indemnity and  contribution  agreements  contained in this Section
are in addition to any liability that the  Indemnifying  Parties may have to the
Indemnified Parties.

     6.   Rule 144

          The Company  shall file the  reports  required to be filed by it under
the  Securities  Act and the Exchange Act in a timely manner and, if at any time
the Company is not required to file such reports, they will, upon the request of
any Holder,  make publicly  available other  information so long as necessary to
permit  sales of its  securities  pursuant  to Rule  144.  The  Company  further

<PAGE>

covenants  that it will take such  further  action as any Holder may  reasonably
request,  all to the extent  required from time to time to enable such Holder to
sell Registrable Securities without registration under the Securities Act within
the limitation of the  exemptions  provided by Rule 144. Upon the request of any
Holder,  the Company shall deliver to such Holder a written  certification  of a
duly authorized officer as to whether it has complied with such requirements.

     7.   Miscellaneous

          (a) Remedies.  In the event of a breach by the Company or by a Holder,
of any of their obligations under this Agreement, each Holder or the Company, as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific  performance of its rights under this  Agreement.  The Company and each
Holder agree that monetary damages would not provide  adequate  compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement  and  hereby  further  agrees  that,  in the event of any  action  for
specific  performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

          (b) No  Inconsistent  Agreements.  Neither  the Company nor any of its
subsidiaries  has,  as of the date  hereof,  nor shall the Company or any of its
subsidiaries,  on or after the date of this Agreement,  enter into any agreement
with respect to its securities that is  inconsistent  with the rights granted to
the Holders in this Agreement or otherwise conflicts with the provisions hereof.
Neither the Company nor any of its subsidiaries has previously  entered into any
agreement granting any registration rights with respect to any of its securities
to any Person except under the Company's registration statements on Form S-3 and
S-8 currently on file with the  Commission and except as set forth under Section
7(c) below.  Without  limiting  the  generality  of the  foregoing,  without the
written consent of the Holders of a majority of the then outstanding Registrable
Securities,  the Company  shall not grant to any Person the right to request the
Company to register  any  securities  of the Company  under the  Securities  Act
unless the rights so granted are subject in all  respects to the prior rights in
full of the  Holders  set forth  herein,  and are not  otherwise  in conflict or
inconsistent with the provisions of this Agreement.

          (c) No Piggyback on  Registrations.  Except for shares of Common Stock
issuable in  connection  with (i) up to  $1,000,000  of  financings as permitted
pursuant to Section 4.9(a)(iv) of the Purchase Agreement and (ii) 100,000 shares
of Common  Stock  issuable by the Company  upon the  exercise of a common  stock
purchase  warrant  issued  to P.F.  Cohn,  neither  the  Company  nor any of its
security  holders (other than the Holders in such capacity  pursuant hereto) may
include  securities of the Company in the Registration  Statement other than the
Common Stock to be issued under the Purchase  Agreement,  and the Company  shall
not  enter  into  any  agreement   providing  any  such  right  to  any  of  its
securityholders.

<PAGE>

          (d)  Piggy-Back  Registrations.  If at  any  time  the  Company  shall
determine  to prepare  and file with the  Commission  a  registration  statement
relating to an offering  for its own account or the account of others  under the
Securities  Act of any of its  equity  securities  at any time when there is not
then an effective Registration Statement,  other than registration statements on
Form S-4 or Form S-8 (each as  promulgated  under the  Securities  Act) or their
then equivalents relating to equity securities to be issued solely in connection
with any acquisition of any entity or business or equity securities  issuable in
connection with stock option or other employee  benefit plans, the Company shall
send  to  each  holder  of  Registrable   Securities   written  notice  of  such
determination  and, if within twenty (20) days after receipt of such notice, any
such holder  shall so request in  writing,  the  Company  shall  include in such
registration statement all or any part of the Registrable Securities such holder
requests to be registered,  except that if, in connection with any  Underwritten
Offering  for the  account of the Company the  managing  underwriter(s)  thereof
shall impose a  limitation  on the number of shares of Common Stock which may be
included  in  the  registration   statement  because,  in  such  underwriter(s)'
judgment,  such limitation is necessary to effect an orderly public distribution
of securities covered thereby, then the Company shall be obligated to include in
such  registration  statement  only  such  limited  portion  of the  Registrable
Securities  for to which such  holder has  requested  inclusion  hereunder.  Any
exclusion  of  Registrable  Securities  shall be made pro rata among the holders
seeking  to  include  Registrable  Securities,  in  proportion  to the number of
Registrable Securities sought to be included by such holders; provided, however,
that the Company shall not exclude any Registrable Securities unless the Company
has first  excluded  all  outstanding  securities  the  holders of which are not
entitled by right to inclusion of securities in such registration statement; and
provided,  further,  however,  that,  after  giving  effet  to  the  immediately
preceding  proviso,  any exclusion of Registrable  Securities  shall be made pro
rata  with  holders  of  other  securities  having  the  right to  include  such
securities  in  such  registration   statement.  No  right  to  registration  of
Registrable  Securities  under  this  Section  shall be  construed  to limit any
registration otherwise required hereunder.

          (e)  Amendments  and  Waivers.   The  provisions  of  this  Agreement,
including  the  provisions  of this  sentence,  may not be amended,  modified or
supplemented,  and waivers or consents to departures from the provisions  hereof
may not be given,  unless the same shall be in writing and signed by the Company
and the  Holders  of at least a  majority  of the then  outstanding  Registrable
Securities;  provided,  however,  that,  for  the  purposes  of  this  sentence,
Registrable  Securities that are owned, directly or indirectly,  by the Company,
or an Affiliate of the Company are not deemed  outstanding.  Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect
to a matter that relates  exclusively to the rights of Holders and that does not
directly  or  indirectly  affect  the  rights of other  Holders  may be given by
Holders  of at least a  majority  of the  Registrable  Securities  to which such
waiver or  consent  relates;  provided,  however,  that the  provisions  of this
sentence may not be amended, modified, or supplemented except in accordance with
the provisions of the immediately preceding sentence.

          (f) Notices. Any and all notices or other communications or deliveries
required or permitted to be provided  hereunder shall be in writing and shall be

     If to any other Person who is then the registered Holder:

                    To the address of such Holder as it appears in the stock
                    transfer books of the Company

or such other  address as may be designated  in writing  hereafter,  in the same
manner, by such Person.

          (g) Successors and Assigns.  This Agreement shall inure to the benefit
of and be  binding  upon the  successors  and  permitted  assigns of each of the
parties  and shall  inure to the  benefit of each  Holder.  The  Company may not
assign its rights or obligations  hereunder without the prior written consent of
each  Holder.  The Holders may assign its rights  hereunder in the manner and to
the Persons as permitted under the Purchase Agreement.

          (h)  Assignment  of  Registration  Rights.  The rights of the  Holders
hereunder,  including  the  right  to  have  the  Company  register  for  resale
Registrable Securities in accordance with the terms of this Agreement,  shall be
automatically  assignable by the Holders to any assignee or transferee of all or
a portion of the shares of  Preferred  Stock,  the  Warrants or the  Registrable
Securities  if: (i) the Holders agree in writing with the transferee or assignee
to assign such rights,  and a copy of such agreement is furnished to the Company
within a reasonable  time after such  assignment,  (ii) the Company is, within a
reasonable time after such transfer or assignment, furnished with written notice
of (a)  the  name  and  address  of such  transferee  or  assignee,  and (b) the
securities  with respect to such  registration  rights are being  transferred or
assigned, (iii) following such transfer or assignment the further disposition of
such securities by the transferee or assignees  restricted  under the Securities
Act and applicable state securities laws, (iv) at or before the time the Company
receives the written  notice  contemplated  by clause (ii) of this Section,  the
transferee or assignee  agrees in writing with the Company to be bound by all of
the provisions of this Agreement,  and (v) such transfer shall have been made in
accordance  with the  applicable  requirements  of the Purchase  Agreement.  The
rights to assignment shall apply to the Holders' (and to subsequent)  successors
and assigns.

          (i)  Counterparts.  This  Agreement  may be  executed in any number of
counterparts,  each of which when so executed  shall be deemed to be an original
and, all of which taken together shall constitute one and the same Agreement. In

<PAGE>

the event that any  signature  is  delivered  by  facsimile  transmission,  such
signature shall create a valid binding  obligation of the party executing (or on
whose behalf such signature is executed) the same with the same force and effect
as if such facsimile signature were the original thereof.

          (j) Governing Law;  Submission to Jurisdiction;.  This Agreement shall
be governed by and  construed  in  accordance  with the laws of the State of New
York,  without  regard to  principles  of conflicts  of law. The Company  hereby
irrevocably  submits to the  jurisdiction of any New York state court sitting in
the Borough of Manhattan in the City of New York or any federal court sitting in
the Borough of Manhattan in the City of New York (collectively,  the "New York")
in respect of any Proceeding  arising out of or relating to this Agreement,  and
irrevocably  accepts for itself and in respect of its  property,  generally  and
unconditionally,  jurisdiction of the New York Courts.  The Company  irrevocably
waives to the fullest extent it may  effectively do so under  applicable law any
objection  that it may now or  hereafter  have to the laying of the venue of any
such  Proceeding  brought  in any New York  Court  and any  claim  that any such
Proceeding  brought  in any New York Court has been  brought in an  inconvenient
forum.  Nothing  herein shall affect the right of any Holder to serve process in
any manner  permitted  by law or to  commence  legal  proceedings  or  otherwise
proceed against the company in any other jurisdiction.

          (k)  Cumulative Remedies.  The remedies provided herein are cumulative
and not exclusive of any remedies provided by law.

          (l) Severability.  If any term, provision,  covenant or restriction of
this  Agreement  is held by a court of  competent  jurisdiction  to be  invalid,
illegal,  void  or  unenforceable,  the  remainder  of  the  terms,  provisions,
covenants  and  restrictions  set forth  herein  shall  remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto  shall use their  reasonable  efforts to find and  employ an  alternative
means to achieve the same or substantially  the same result as that contemplated
by such term,  provision,  covenant or restriction.  It is hereby stipulated and
declared to be the  intention of the parties  that they would have  executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.

          (m) Headings.  The headings in this  Agreement are for  convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          (n)  Shares  Held by The  Company  and its  Affiliates.  Whenever  the
consent  or  approval  of  Holders  of a  specified  percentage  of  Registrable
Securities is required hereunder,  Registrable Securities held by the Company or
its Affiliates (other than the Purchaser or transferees or successors or assigns
thereof if such  Persons are deemed to be  Affiliates  solely by reason of their
holdings of such  Registrable  Securities)  shall not be counted in  determining
whether  such  consent or  approval  was given by the  Holders of such  required
percentage.

                                VASOMEDICAL, INC.

                                     WARRANT

                               Dated June 25, 1997


     Vasomedical, Inc., a Delaware corporation (the "Company"), hereby certifies
that, for value received,  ________________________, or its registered  assigns
("Holder"), is entitled,  subject to the terms set forth below, to purchase from
the Company up to a total of _______shares of Common Stock, $.001 par value per
share (the "Common  Stock"),  of the Company (each such share, a "Warrant Share"
and all such shares,  the "Warrant  Shares") at an exercise price equal to $2.18
per share (as adjusted from time to time as provided in Section 8, the "Exercise
Price"),  at any time and from time to time from and after the date  hereof  and
through and including June 25, 2002 (the "Expiration  Date"), and subject to the
following terms and conditions:

          1.  Registration of Warrant.  The Company shall register this Warrant,
upon records to be  maintained  by the Company for that  purpose  (the  "Warrant
Register"),  in the name of the  record  Holder  hereof  from time to time.  The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise  hereof or any  distribution to the
Holder,  and for all other  purposes,  and the Company  shall not be affected by
notice to the contrary.

          2.   Registration of Transfers and Exchanges.

               (a) The Company  shall  register  the  transfer of any portion of
this Warrant in the Warrant Register,  upon surrender of this Warrant,  with the

<PAGE>

Form of Assignment  attached  hereto duly completed and signed,  to the Transfer
Agent or to the Company at the office  specified in or pursuant to Section 3(b),
provided, however that the Holder shall not make any transfers to any transferee
pursuant  to this  Section  for the right to acquire  less than  25,000  Warrant
Shares (or the balance of the  Warrant  Shares to which this  Warrant  relates).
Upon any such registration or transfer,  a new warrant to purchase Common Stock,
in  substantially  the  form of this  Warrant  (any  such  new  warrant,  a "New
Warrant"), evidencing the portion of this Warrant so transferred shall be issued
to the  transferee and a New Warrant  evidencing  the remaining  portion of this
Warrant not so transferred,  if any, shall be issued to the transferring Holder.
The acceptance of the New Warrant by the transferee  thereof shall be deemed the
acceptance of such  transferee of all of the rights and  obligations of a holder
of a Warrant.

               (b) This Warrant is  exchangeable,  upon the surrender  hereof by
the Holder to the office of the Company specified in or pursuant to Section 3(b)
for one or more New Warrants,  evidencing in the aggregate the right to purchase
the number of Warrant Shares which may then be purchased hereunder. Any such New
Warrant will be dated the date of such exchange.

          3.   Duration and Exercise of Warrants.

               (a) This Warrant shall be exercisable by the registered Holder on
any business day before 5:30 P.M.,  Eastern  time,  at any time and from time to
time on or after the date hereof to and including the  Expiration  Date. At 5:30
P.M.,  Eastern  time on the  Expiration  Date,  the portion of this  Warrant not
exercised  prior thereto shall be and become void and of no value.  Prior to the
Expiration  Date,  the Company  may not call or  otherwise  redeem this  Warrant
without the prior written consent of the Holder.

               (b) Subject to Sections  2(b),  6 and 10, upon  surrender of this
Warrant,  with the Form of Election to Purchase  attached  hereto duly completed
and signed,  to the Company at its office at 180 Linden  Avenue,  Westbury,  New
York 11590, Attention:  Chief Financial Officer, or at such other address as the
Company may specify in writing to the then registered  Holder,  and upon payment
of the Exercise Price multiplied by the number of Warrant Shares that the Holder
intends to purchase hereunder,  in lawful money of the United States of America,
in cash or by  certified or official  bank check or checks,  all as specified by
the Holder in the Form of Election to Purchase,  the Company shall promptly (but
in no event  later than 3 business  days  after the Date of  Exercise)  issue or
cause to be issued and cause to be delivered to or upon the written order of the
Holder and in such name or names as the Holder may designate,  a certificate for
the Warrant  Shares  issuable upon such exercise,  free of  restrictive  legends
other than as required by applicable law. Any person so designated by the Holder
to receive  Warrant  Shares  shall be deemed to have become  holder of record of
such Warrant Shares as of the Date of Exercise of this Warrant.

<PAGE>

               A "Date of  Exercise"  means the date on which the Company  shall
have  received (i) this Warrant (or any New Warrant,  as  applicable),  with the
Form of Election to Purchase  attached  hereto (or attached to such New Warrant)
appropriately  completed and duly signed, and (ii) payment of the Exercise Price
for the  number  of  Warrant  Shares so  indicated  by the  holder  hereof to be
purchased.

               (c) This Warrant shall be exercisable, either in its entirety or,
from time to time, for a portion of the number of Warrant  Shares.  If less than
all of the  Warrant  Shares  which  may be  purchased  under  this  Warrant  are
exercised  at any time,  the Company  shall issue or cause to be issued,  at its
expense,  a New Warrant evidencing the right to purchase the remaining number of
Warrant Shares for which no exercise has been evidenced by this Warrant.

          4. Piggyback  Registration Rights. During the term of this Warrant the
Company may not file any registration statement with the Securities and Exchange
Commission  (other than  registration  statements  of the Company filed or to be
filed on Form S-8 or Form S-4 including supplements thereto, each as promulgated
under the Securities  Act of 1933, as amended,  pursuant to which the Company is
registering  securities  pursuant to a Company employee benefit plan or pursuant
to a merger,  acquisition or similar  transaction)  unless the Company  provides
each of the Holder and Robinson Silverman Peace Aronsohn & Berman LLP, attention
Eric L. Cohen with not less than four  business  days notice of its intention to
file such  registration  statement  and  provides  the  Purchaser  the option to
include any or all of the  applicable  Warrant  Shares  therein.  The  piggyback
registration  rights  granted  to the  Holder  pursuant  to this  Section  shall
continue  until all of the Holder's  Warrant Shares have been sold in accordance
with an effective registration statement or upon the expiration of this Warrant.
The Company will pay all of its registration expenses in connection therewith.

          5.  Demand  Registration  Rights.  At any time during the term of this
Warrant  when the Warrant  Shares are not  registered  pursuant to an  effective
registration  statement,   the  Holder  may  make  a  written  request  for  the
registration   under  the   Securities  Act  of  1933,  as  amended  (a  "Demand
Registration"), of all of the Warrant Shares (the "Registrable Securities"), and
the Company  shall use its best  efforts to effect such Demand  Registration  as
promptly as possible, but in any case within 90 days thereafter. Any request for
a  Demand  Registration  shall  specify  the  aggregate  number  of  Registrable
Securities  proposed to be sold and shall also  specify the  intended  method of
disposition  thereof.  The  right to  cause a  registration  of the  Registrable
Securities  under this Section 5 shall be limited to one such  registration.  In
any registration initiated as a Demand Registration, the Company will pay all of
its registration expenses in connection  therewith.  A Demand Registration shall
not be counted as a Demand Registration hereunder until such Demand Registration
has been  declared  effective  by the  Securities  and Exchange  Commission  and
maintained  continuously  effective  for a period  of at least  360 days or such
shorter period when all Registrable  Securities  included therein have been sold
in accordance with such Demand Registration,  provided, however that any days on
which such registration statement is not effective or on which the Holder is not

<PAGE>

permitted by the Company or any  governmental  authority to sell Warrant  Shares
under such registration statement shall not count towards such 360 day period.

          6. Payment of Taxes. The Company will pay all documentary  stamp taxes
attributable  to the  issuance  of  Warrant  Shares  upon the  exercise  of this
Warrant;  provided,  however,  that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the registration
of any  certificates for Warrant Shares or Warrants in a name other than that of
the Holder, and the Company shall not be required to issue or cause to be issued
or deliver or cause to be delivered the  certificates  for Warrant Shares unless
or until the person or persons  requesting the issuance  thereof shall have paid
to the  Company  the  amount  of  such  tax or  shall  have  established  to the
satisfaction  of the Company  that such tax has been paid.  The Holder  shall be
responsible for all other tax liability that may arise as a result of holding or
transferring this Warrant or receiving Warrant Shares upon exercise hereof.

          7. Replacement of Warrant. If this Warrant is mutilated,  lost, stolen
or destroyed,  the Company may in its discretion  issue or cause to be issued in
exchange and substitution for and upon  cancellation  hereof,  or in lieu of and
substitution for this Warrant, a New Warrant,  but only upon receipt of evidence
reasonably  satisfactory  to the Company of such loss,  theft or destruction and
indemnity, if requested,  satisfactory to it. Applicants for a New Warrant under
such circumstances shall also comply with such other reasonable  regulations and
procedures and pay such other reasonable charges as the Company may prescribe.

          8. Reservation of Warrant Shares.  The Company  covenants that it will
at all times reserve and keep  available out of the aggregate of its  authorized
but  unissued  Common  Stock,  solely for the  purpose of  enabling  it to issue
Warrant Shares upon exercise of this Warrant as herein  provided,  the number of
Warrant Shares which are then issuable and deliverable upon the exercise of this
entire  Warrant,  free from  preemptive  rights or any other  actual  contingent
purchase  rights of persons  other than the  Holders  (taking  into  account the
adjustments  and  restrictions  of Section  9). The Company  covenants  that all
Warrant Shares that shall be so issuable and  deliverable  shall,  upon issuance
and the payment of the applicable  Exercise  Price in accordance  with the terms
hereof, be duly and validly authorized, issued and fully paid and nonassessable.

          9.  Certain  Adjustments.  The  Exercise  Price and  number of Warrant
Shares  issuable upon  exercise of this Warrant are subject to  adjustment  from
time to time as set forth in this  Section 9. Upon each such  adjustment  of the
Exercise Price pursuant to this Section 9, the Holder shall  thereafter prior to
the Expiration  Date be entitled to purchase,  at the Exercise  Price  resulting
from such  adjustment,  the number of Warrant Shares obtained by multiplying the
Exercise Price in effect  immediately  prior to such adjustment by the number of
Warrant Shares issuable upon exercise of this Warrant  immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

<PAGE>

               (a)  If  the   Company,   at  any  time  while  this  Warrant  is
outstanding,  (i) shall pay a stock dividend (except scheduled dividends paid on
outstanding preferred stock as of the date hereof which contain a stated divided
rate) or otherwise make a distribution or  distributions on shares of its Common
Stock (as  defined  below) or on any other  class of  capital  stock and not the
Common Stock)  payable in shares of Common  Stock,  (ii)  subdivide  outstanding
shares  of  Common  Stock  into a larger  number  of  shares,  or (iii)  combine
outstanding shares of Common Stock into a smaller number of shares, the Exercise
Price  shall be  multiplied  by a fraction of which the  numerator  shall be the
number of shares of Common Stock (excluding treasury shares, if any) outstanding
before such event and of which the denominator  shall be the number of shares of
Common Stock (excluding  treasury shares,  if any) outstanding after such event.
Any adjustment made pursuant to this Section shall become effective  immediately
after the record date for the determination of stockholders  entitled to receive
such dividend or distribution and shall become effective  immediately  after the
effective date in the case of a subdivision or  combination,  and shall apply to
successive subdivisions and combinations.

               (b) In case of any  reclassification  of the  Common  Stock,  any
consolidation or merger of the Company with or into another person,  the sale or
transfer  of  all or  substantially  all of the  assets  of the  Company  or any
compulsory  share exchange  pursuant to which the Common Stock is converted into
other  securities,  cash or  property,  then the  Holder  shall  have the  right
thereafter  to  exercise  this  Warrant  only into the shares of stock and other
securities  and  property  receivable  upon or deemed to be held by  holders  of
Common Stock  following  such  reclassification,  consolidation,  merger,  sale,
transfer or share exchange,  and the Holder shall be entitled upon such event to
receive  such amount of  securities  or property  equal to the amount of Warrant
Shares such Holder would have been  entitled to had such Holder  exercised  this
Warrant immediately prior to such reclassification, consolidation, merger, sale,
transfer or share exchange.  The terms of any such consolidation,  merger, sale,
transfer or share exchange shall include such terms so as to continue to give to
the Holder the right to receive the  securities  or  property  set forth in this
Section   9(b)  upon  any   exercise   following   any  such   reclassification,
consolidation, merger, sale, transfer or share exchange.

               (c)  If  the   Company,   at  any  time  while  this  Warrant  is
outstanding, shall distribute to all holders of Common Stock (and not to holders
of this Warrant)  evidences of its  indebtedness or assets or rights or warrants
to  subscribe  for or purchase  any  security  (excluding  those  referred to in
Sections 9(a), (b) and (d)),  then in each such case the Exercise Price shall be
determined by multiplying the Exercise Price in effect  immediately prior to the
record date fixed for  determination  of  stockholders  entitled to receive such
distribution by a fraction of which the denominator  shall be the Exercise Price
determined  as of the record date  mentioned  above,  and of which the numerator
shall be such Exercise Price on such record date less the then fair market value
at such record date of the portion of such assets or evidence of indebtedness so
distributed applicable to one outstanding share of Common Stock as determined by
the Company's  independent  certified public accountants that regularly examines
the financial statements of the Company (an "Appraiser").

<PAGE>

               (d) If,  at any time  while  this  Warrant  is  outstanding,  the
Company  shall  issue or cause to be issued  rights or  warrants  to  acquire or
otherwise  sell or  distribute  shares of Common  Stock to all holders of Common
Stock for a consideration per share less than the Exercise Price then in effect,
then,  forthwith upon such issue or sale, the Exercise Price shall be reduced to
the price  (calculated to the nearest cent) determined by dividing (i) an amount
equal  to the sum of (A) the  number  of  shares  of  Common  Stock  outstanding
immediately  prior to such issue or sale multiplied by the Exercise  Price,  and
(B) the  consideration,  if any, received or receivable by the Company upon such
issue or sale by (ii) the total  number of  shares of Common  Stock  outstanding
immediately after such issue or sale.

               (e) For the  purposes of this  Section 9, the  following  clauses
shall also be applicable:

                    (i) Record Date.  In case the Company shall take a record of
the holders of its Common Stock for the purpose of entitling them (A) to receive
a  dividend  or other  distribution  payable in Common  Stock or in  Convertible
Securities,  or (B) to subscribe  for or purchase  Common  Stock or  Convertible
Securities, then such record date shall be deemed to be the date of the issue or
sale of the shares of Common  Stock  deemed to have been issued or sold upon the
declaration  of such  dividend or the making of such other  distribution  or the
date of the granting of such right of subscription or purchase,  as the case may
be.

                    (ii) Treasury  Shares.  The number of shares of Common Stock
outstanding  at any given time shall not include  shares owned or held by or for
the account of the  Company,  and the  disposition  of any such shares  shall be
considered an issue or sale of Common Stock.

               (f) All  calculations  under this  Section 8 shall be made to the
nearest cent or the nearest 1/100th of a share, as the case may be.

               (g) Whenever the Exercise  Price is adjusted  pursuant to Section
9(c) above,  the Holder,  after receipt of the  determination  by the Appraiser,
shall  have the  right to  select  an  additional  appraiser  (which  shall be a
nationally  recognized  accounting  firm), in which case the adjustment shall be
equal to the average of the adjustments recommended by each of the Appraiser and
such  appraiser.  The Holder  shall  promptly  mail or cause to be mailed to the
Company,  a notice  setting forth the Exercise  Price after such  adjustment and
setting forth a brief  statement of the facts  requiring such  adjustment.  Such
adjustment  shall become effective  immediately  after the record date mentioned
above.

               (h)  If:

                               (i) the Company shall declare a dividend (or any 
                                   other distribution) on its Common Stock; or
<PAGE>

                              (ii) the Company shall declare a special 
                                   nonrecurring cash dividend on or a 
                                   redemption of its Common Stock; or

                             (iii) the Company  shall  authorize the granting to
                                   all  holders  of the Common  Stock  rights or
                                   warrants to  subscribe  for or  purchase  any
                                   shares  of  capital  stock of any class or of
                                   any rights; or

                              (iv) the  approval  of  any  stockholders  of  the
                                   Company shall be required in connection  with
                                   any  reclassification  of the Common Stock of
                                   the Company,  any  consolidation or merger to
                                   which  the  Company  is a party,  any sale or
                                   transfer of all or  substantially  all of the
                                   assets  of the  Company,  or  any  compulsory
                                   share  exchange  whereby the Common  Stock is
                                   converted  into  other  securities,  cash  or
                                   property; or

                               (v) the Company shall authorize the voluntary
                                   dissolution, liquidation or winding up of
                                   the affairs of the Company,

stating  (x) the date on which a record is to be taken for the  purpose  of such
dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken,  the date as of which  the  holders  of  Common  Stock of record to be
entitled to such dividend, distributions,  redemption, rights or warrants are to
be  determined  or (y) the date on which such  reclassification,  consolidation,
merger,  sale,  transfer or share  exchange is expected to become  effective  or
close,  and the date as of which it is expected  that holders of Common Stock of
record  shall  be  entitled  to  exchange  their  shares  of  Common  Stock  for
securities,  cash or other  property  deliverable  upon  such  reclassification,
consolidation,  merger, sale, transfer, share exchange, dissolution, liquidation
or winding up;  provided,  however,  that the failure to mail such notice or any
defect  therein or in the mailing  thereof  shall not affect the validity of the
corporate action required to be specified in such notice.

cause to be issued  fractional  Warrant  Shares on the exercise of this Warrant.
The number of full Warrant  Shares which shall be issuable  upon the exercise of

                    VASOMEDICAL, INC. ANNOUNCES $3.0 MILLION
                                PRIVATE PLACEMENT

     Westbury,  New  York,  June 30,  1997 --  Vasomedical,  Inc.  (NASDAQ:VASO;
http://vasomedical.com)  announced  that it has  executed an  agreement  with an
investment  fund  for a  private  placement  of  $3.0  million  of 5%  Series  B
Convertible  Preferred  Shares pursuant to Regulation D of the Securities Act of
1933.  The  transaction  was  facilitated by Wharton  Capital,  a New York based
financial consulting firm.

     Proceeds from the offering  will fund working  capital  needs,  such as for
stepped-up  marketing  efforts and R&D focused on developing the next generation
model of EECP and  conducting  clinical  studies to expand  EECP 's  therapeutic
indications and take advantage of its current labeling for acute conditions.  In
addition,  the  Company  will  engage in a  communication  campaign  designed to
broadly disseminate the results of its now completed  MUST-EECP trial,  expected
to  be  announced  in  the  fall  of  1997.  MUST-EECP  is  a  company-sponsored
randomized,  controlled and  double-blinded  study in which  teaching  hospitals
affiliated with the medical  schools of Columbia,  Harvard,  Loyola  University,
UCSF, University of Pittsburgh and Yale and Grant/Riverside  Methodist Hospitals
have participated.

     Anthony Viscusi, President and CEO of Vasomedical, stated that "the Company
is increasingly  confident about the future of EECP as a mainstream treatment of
coronary artery disease throughout the therapeutic continuum.  We are entering a
new  evolutionary  stage,  and this capital infusion will enable us to move more
rapidly in the  establishment of new  indications,  among which congestive heart
failure  and  peripheral  vascular  disease  are  priorities,  and thus  further
capitalize on the full intrinsic value of our EECP technology for the benefit of
patients, the medical profession and our shareholders."

     Vasomedical is a medical  technology  company  devoted to the  development,
manufacture   and    commercialization    of   innovative   and   cost-effective
cardiovascular products and processes.
