NEITHER THIS WARRANT NOR THE SHARES OF COMMON STOCK  ISSUABLE  UPON  EXERCISE OF
THIS WARRANT HAVE BEEN REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
AND NEITHER  THIS WARRANT NOR SUCH SHARES MAY BE SOLD,  ENCUMBERED  OR OTHERWISE
TRANSFERRED  EXCEPT PURSUANT TO AN EFFECTIVE  REGISTRATION  STATEMENT UNDER SUCH

AS DEFINED IN THE WARRANT

                          COMMON STOCK PURCHASE WARRANT
                                       OF
                         NATIONAL SCIENTIFIC CORPORATION


     This is to  certify  that,  FOR VALUE  RECEIVED,  ________________  with an
address  at   ______________________________   (and  or  its  assign(s)   and/or
transferee(s)) (hereinafter, each a "Holder" and collectively the "Holders"), is
entitled to purchase,  subject to the provisions of this Warrant,  from National
Scientific  Corporation,  a Texas  corporation  (the  "Company"),  at an initial
exercise  price equal to $.10 per  share__________________(________)  fully paid
and  non-assessable  shares of Common Stock,  par value $.01 per share  ("Common
Stock").  The shares of Common  Stock  deliverable  upon such  exercise,  and as
adjusted  from  time-to-time  as  provided  in  this  Warrant,  are  hereinafter
sometimes  referred  to as  "Warrant  Stock,"  and the  exercise  price  for the
purchase of a share of Common  Stock  pursuant to this  Warrant in effect at any
time and as adjusted from time-to-time is hereinafter  sometimes  referred to as
the "Exercise Price." The aggregate purchase price payable for the Warrant Stock
purchasable  hereunder  is referred to as the  "Aggregate  Purchase  Price." The
Aggregate  Purchase  Price is not  subject  to  adjustment.  In the  event of an
adjustment to the Exercise Price, as provided in Section 6 herein, the number of
shares of Warrant  Stock  deliverable  upon  exercise of this  Warrant  shall be
adjusted by dividing  the  Aggregate  Purchase  Price by the  Exercise  Price in
effect immediately after such adjustment.

     This  warrant and  additional  warrants of like tenor,  including  warrants
issued in exchange and/or substitution  thereof  (collectively,  the "Warrants")
were originally  issued in connection with a the execution of a Letter of Intent
between the Company and Casimir Capital L.P., dated February 9, 2004, ("Letter")
with respect to a proposed offering of securities by the Company ("Offering").

     1.   DEFINITIONS. The following terms have the meanings set forth below:

          "Current  Market Value" of a share of Warrant Stock as of a particular
date (the "Determination Date") shall mean:

          a.   If the Common Stock is listed on a national  securities  exchange
     or admitted to unlisted  trading  privileges on such exchange or listed for
     trading on the NASDAQ  National  Market,  the current market value shall be
     the last reported sale price of the Common Stock on such exchange or market
     on the last  business  day prior to the date of exercise of this Warrant or
     if no such  sale is made on such day,  the  average  closing  bid and asked
     prices for such day on such exchange or market; or

          b.   If the  Common  Stock is not so listed or  admitted  to  unlisted
     trading  privileges,  but is  traded on the  NASDAQ  SmallCap  Market,  the
     current  market  value  shall be the  average of the  closing bid and asked
     prices  for  such  day on such  market  and if the  Common  Stock is not so
     traded,  the current  market  value shall be the mean of the last  reported
     bid-and asked prices reported by the National Quotation Bureau, Inc. on the
     last business day prior to the date of the exercise of this Warrant; or

          c.   If the  Common  Stock is not so listed or  admitted  to  unlisted
     trading  privileges  and bid and  asked  prices  are not so  reported,  the
     current  market value shall be an amount,  not less than book value thereof
     as at the end of the most recent fiscal year of the Company ending prior to
     the date of the  exercise of the  Warrant,  determined  in such  reasonable
     manner as may be prescribed by the Board of Directors of the Company.

          "Convertible Securities" shall mean evidences of indebtedness,  shares
of stock or other securities,  including but not limited to options, warrants or
purchase, subscription or other rights, which are convertible into, exchangeable
or exercisable  for, or represent the right to receive,  with or without payment
of  additional  consideration  in cash or  property,  shares of Common Stock (or
other Convertible  Securities),  either  immediately or upon the occurrence of a
specified date or a specified event.

          "Exercise  Period" shall mean the period commencing on the date hereof
and ending at 5 p.m., eastern time on the day preceding the seventh  anniversary
of the date hereof.

          "Permitted  Issuances"  shall mean (i) Common Stock issuable or issued
to employees,  consultants or directors of the Company  pursuant to a stock plan
or other  compensation  arrangement  approved by the Board of  Directors  of the
Company,  but in no event, more than Eight Million shares in the aggregate,  and
(ii) Common  Stock  issued or issuable  upon  conversion  of the Warrants or any
other securities  exercisable or exchangeable for, or convertible into shares of
Common Stock outstanding as of February 9, 2004.

     2.   EXERCISE OF WARRANT.

          (a)  This  Warrant may be exercised in whole or in part at any time or
     from time to time  commencing on the date hereof and until February 9, 2011
     (the "Exercise Period"),  provided,  however,  that if either such day is a
     day on which banking  institutions  in the State of New York are authorized
     by law to close,  then on the next succeeding day which shall not be such a
     day. This Warrant may be exercised by presentation  and surrender hereof to

                                       2
<PAGE>

     the Company at its principal office, or at the office of its stock transfer
     agent,  if any,  with the Purchase  Form annexed  hereto duly  executed and
     accompanied  by payment of the  Exercise  Price for the number of shares of
     Warrant  Stock  specified in such form. As soon as  practicable  after each
     such exercise of this Warrant,  but not later than seven days from the date
     of such  exercise,  the  Company  shall  issue and  deliver to the Holder a
     certificate or  certificates  for the shares of Warrant Stock issuable upon
     such  exercise,  registered in the name of the Holder or its  designee.  If
     this  Warrant  should be exercised in part only,  the Company  shall,  upon
     surrender  of this  Warrant  for  cancellation,  execute  and deliver a new
     Warrant evidencing the rights of the Holder thereof to purchase the balance
     of the shares of Warrant Stock purchasable thereunder.  Upon receipt by the
     Company of this Warrant at its office,  or by the stock  transfer  agent of
     the Company at its office, in proper form for exercise, the Holder shall be
     deemed to be the  holder of record of the shares of Common  Stock  issuable
     upon such  exercise,  notwithstanding  that the stock transfer books of the
     Company shall then be closed or that certificates  representing such shares
     of Common Stock shall not then be physically delivered to the Holder.

          (b)  In lieu of the payment method set forth in Section (a) above,  at
     any time  during the  Exercise  Period,  the  Holder  may,  at its  option,
     exchange this Warrant, in whole or in part (a "Warrant Exchange"),  without
     the payment by the Holder of any additional  consideration  into the number
     of shares of Warrant Stock  determined in accordance with this Section (b),
     by surrendering  this Warrant at the principal  office of the Company or at
     the office of its stock  transfer  agent,  accompanied  by a notice stating
     such  Holder's  intent to effect  such  exchange,  the  number of shares of
     Warrant  Stock to be  exchanged  and the date on which the Holder  requests
     that such Warrant  Exchange occur (the "Notice of  Exchange").  The Warrant
     Exchange  shall take place on the date  specified in the Notice of Exchange
     or, if later,  the date the Notice of  Exchange  is received by the Company
     (the  "Exchange  Date").  Certificates  for the shares  issuable  upon such
     Warrant Exchange and, if applicable, a new warrant of like tenor evidencing
     the  balance of the shares  remaining  subject  to this  Warrant,  shall be
     issued as of the Exchange  Date and  delivered  to the Holder  within seven
     days following the Exchange Date. In connection with any Warrant  Exchange,
     this Warrant  shall  represent  the right to subscribe  for and acquire the
     number of shares of Warrant  Stock  (rounded to the next  highest  integer)
     equal to (i) the number of shares of Warrant Stock  specified by the Holder
     in its Notice of  Exchange  (the  "Total  Number")  less (ii) the number of
     shares of Warrant Stock equal to the quotient  obtained by dividing (A) the
     product of the Total  Number  and the  existing  Exercise  Price by (B) the
     Current Market Value of a share of Common Stock. Current Market Value shall
     have the meaning set forth in Section (1) above,  except that for  purposes
     hereof,  the date of exercise,  as used in such Section (1), shall mean the
     Exchange Date.

     3.   RESERVATION  OF  SHARES/FRACTIONAL  SHARES.  The Company hereby agrees
that at all times there shall be reserved  for  issuance  and/or  delivery  upon
exercise  of this  Warrant  such  number of  shares of Common  Stock as shall be
required for issuance and delivery upon exercise of this Warrant. If the Company
hereafter lists its Common Stock on any national securities exchange, the Nasdaq
National Market or the Nasdaq SmallCap Market,  it shall use its best efforts to
keep the Warrant  Stock  authorized  for listing on such exchange upon notice of
issuance. No fractional shares or script representing fractional shares shall be
issued upon the  exercise of this  Warrant.  With  respect to any  fraction of a

                                       3
<PAGE>

share,  called for upon exercise hereof,  the Company shall pay to the Holder an
amount in cash equal to such fraction  multiplied by the Current Market Value of
a share of Warrant Stock.

     4.   EXCHANGE,  TRANSFER,  ASSIGNMENT OR LOSS OF WARRANT. This Warrant (and
all rights  hereunder) is exchangeable,  without  expense,  at the option of the
Holder,  upon  presentation and surrender hereof to the Company or at the office
of  its  stock  transfer   agent,  if  any,  for  other  Warrants  of  different
denominations  entitling the holder or any assignee and/or transferee thereof to
purchase in the aggregate the same number of shares of Common Stock  purchasable
hereunder. Upon surrender of this Warrant to the Company or at the office of its
stock  transfer  agent,  if any, with the  Assignment  Form annexed  hereto duly
executed  and funds  sufficient  to pay any  transfer  tax,  the Company  shall,
without  charge,  execute and deliver a new Warrant in the name of the  assignee
and/or  transferee named in such instrument of assignment and this Warrant shall
promptly  be  canceled.  This  Warrant  may be  divided or  combined  with other
Warrants which carry the same rights upon  presentation  hereof at the office of
the Company or at the office of its stock transfer agent, if any,  together with
a written notice  specifying the names and  denominations  in which new Warrants
are to be issued and signed by the Holder  hereof.  The term  "Warrant"  as used
herein  includes  any  Warrants  into  which  this  Warrant  may be  divided  or
exchanged.  Upon  receipt by the Company of evidence  satisfactory  to it of the
loss,  theft,  destruction  or mutilation  of this Warrant,  and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and upon
surrender  and  cancellation  of this Warrant,  if  mutilated,  the Company will
execute and deliver a new Warrant of like tenor.  Any such new Warrant  executed
and delivered shall constitute an additional  contractual obligation on the part
of the  Company,  whether or not this  Warrant so lost,  stolen,  destroyed,  or
mutilated shall be at any time enforceable by anyone.

     5.   RIGHTS OF THE HOLDER. The Holder shall not, by virtue of this Warrant,
be  entitled to any rights of a  stockholder  in the  Company,  either at law or
equity,  and the  rights of the Holder are  limited  to those  expressed  in the
Warrant and are not  enforceable  against  the Company  except to the extent set
forth herein.  In addition,  no provision  hereof, in the absence of affirmative
action by Holder to purchase shares of Common Stock,  and no enumeration  herein
of the rights or privileges of Holder  hereof,  shall give rise to any liability
of such Holder for the purchase price of any Common Stock or as a stockholder of
Company,  whether  such  liability  is  asserted by Company or by  creditors  of
Company.

     6.   ANTI-DILUTION PROVISIONS. The Exercise Price in effect at any time and
the number and kind of  securities  purchasable  upon  exercise of each  Warrant
shall be subject to adjustment as follows and the Company shall give each Holder
notice of any event  described  below which  requires an adjustment  pursuant to
this Section 6 at the time of such event:

          (a)  STOCK DIVIDENDS,  SUBDIVISIONS AND COMBINATIONS.  If, at any time
     or from time to time after the date of this Warrant,  the Company shall (i)
     pay a dividend or make a distribution to any holder of its capital stock in
     shares of Common Stock,  (ii)  subdivide its  outstanding  shares of Common
     Stock into a greater number of shares, (iii) combine its outstanding shares
     of  Common  Stock  into a  smaller  number  of  shares  or  (iv)  issue  by
     reclassification  of its Common  Stock any  shares of capital  stock of the
     Company,  the  Exercise  Price shall be adjusted to be equal to a fraction,
     the  numerator  of which  shall be the  Aggregate  Purchase  Price  and the

                                       4
<PAGE>

     denominator of which shall be the number of shares of Common Stock or other
     capital  stock of the Company that the Holder would have owned  immediately
     following  such action had such Warrant been  exercised  immediately  prior
     thereto.  An adjustment  made pursuant to this  Subsection (a) shall become
     effective  immediately  after the record  date in the case of a dividend or
     distribution,  and shall become effective  immediately  after the effective
     date in the case of a  subdivision,  combination or  reclassification,  and
     shall  result  in a  corresponding  adjustment  to the  number of shares of
     Warrant Stock issuable upon exercise of this Warrant.

          (b)  CERTAIN OTHER  DISTRIBUTIONS AND ADJUSTMENTS.  If, at any time or
     from time to time after the date of this  Warrant,  the Company shall issue
     or  distribute  to any  holder of shares of Common  Stock  evidence  of its
     indebtedness,  any other securities of the Company or any cash, property or
     other assets (excluding a subdivision, combination or reclassification,  or
     dividend or distribution payable in shares of Common Stock,  referred to in
     Subsection  (a), and also excluding  cash  dividends or cash  distributions
     paid out of net  profits  legally  available  therefor  in the full  amount
     thereof  (any  such  non-excluded  event  being  herein  called a  "Special
     Dividend")),  the  Exercise  Price  shall be adjusted  by  multiplying  the
     Exercise  Price then in effect by a fraction,  the numerator of which shall
     be the then  Current  Market  Value in  effect on the  record  date of such
     issuance or  distribution  less the fair  market  value (as  determined  in
     accordance  with  paragraph  B. of this  Section 6 (g)) of the  evidence of
     indebtedness,  cash,  securities  or property,  or other  assets  issued or
     distributed  in such  Special  Dividend  applicable  to one share of Common
     Stock and the  denominator  of which shall be the then Current Market Value
     in  effect  on the  record  date  of  such  issuance  or  distribution.  An
     adjustment  made  pursuant to this  Subsection  (b) shall become  effective
     immediately  after the record date of any such  Special  Dividend and shall
     result in a  corresponding  adjustment  to the  number of shares of Warrant
     Stock issuable upon exercise of this Warrant.

          (c)  ISSUANCE OF  ADDITIONAL  SHARES OF COMMON  STOCK AND  CONVERTIBLE
     SECURITIES.

               (i)  If at any time the Company shall issue or sell any shares of
          Common  Stock  or  Convertible  Securities  (whether  directly  or  by
          assumption in a merger in which Company is the surviving corporation),
          in exchange for  consideration  in an amount per share of Common Stock
          (determined  by dividing  (i) the total  amount,  if any,  received or
          receivable by the Company in  consideration of the issuance or sale of
          such securities plus the total  consideration,  if any, payable to the
          Company  upon  exercise,   conversion  or  exchange   thereof  ("Total
          Consideration")  by (ii) the  number  of  additional  shares of Common
          Stock  issued,  sold or  issuable  upon the  exercise,  conversion  or
          exchange  of such  securities)  that is less than the  Exercise  Price
          (excluding Permitted Issuances),  then (A) the Exercise Price shall be
          adjusted so that it shall equal the price  determined  by  multiplying
          such Exercise Price by a fraction, the numerator of which shall be the
          number of shares of Common Stock  outstanding  on the date of issuance
          or sale  (calculated  on a fully  diluted  basis as if all  securities
          exercisable, convertible or exchangeable for Common Stock have been so
          exercised, converted or exchanged) plus the number of shares of Common
          Stock which the aggregate offering price would purchase based upon the
          Exercise  Price and the  denominator  of which  shall be the number of

                                       5
<PAGE>

          shares of Common  Stock  outstanding  on the date of  issuance or sale
          (calculated on a fully diluted basis as if all securities exercisable,
          convertible or  exchangeable  for Common Stock have been so exercised,
          converted or exchanged)  plus the maximum number of additional  shares
          of Common  Stock  issued,  sold or  issuable in  connection  with such
          offering or transaction,  and (B) the number of shares of Common Stock
          for which this Warrant is  exercisable  shall be adjusted to equal the
          product   obtained  by  multiplying   the  Exercise  Price  in  effect
          immediately  prior to such  issue or sale by the  number  of shares of
          Common Stock for which this Warrant is exercisable  immediately  prior
          to such issue or sale and dividing the product thereof by the Exercise
          Price resulting from the adjustment made pursuant to clause (A) above.

               (ii) The  provisions  of paragraph (i) of this Section 6(c) shall
          not apply to any  issuance  of  shares  of  Common  Stock for which an
          adjustment  is provided  under  Section 6(a) or 6(b). No adjustment of
          the number of shares of Common Stock for which this  Warrant  shall be
          exercisable  shall be made under  paragraph  (i) of this  Section 6(c)
          upon the  issuance  of any  shares of Common  Stock  which are  issued
          pursuant to the  exercise of any  warrants  or other  subscription  or
          purchase  rights or pursuant  to the  exercise  of any  conversion  or
          exchange rights in any Convertible Securities,  if any such adjustment
          shall  previously have been made upon the issuance of such warrants or
          other rights or upon the issuance of such Convertible Securities.

          (d)  No adjustment in the Exercise Price shall be required unless such
     adjustment  would  require an  increase  or  decrease  of at least one cent
     ($0.01) in such price;  provided,  however,  that any adjustments  which by
     reason of this  Section  6(d) are not  required to be made shall be carried
     forward  and taken into  account in any  subsequent  adjustment;  provided,
     further,  however that adjustments shall be required and made in accordance
     with the  provisions  of this  Section 6 not later than such time as may be
     required in order to preserve the tax-free  nature of a distribution to the
     Holder of this Warrant or Common Stock  issuable upon the exercise  hereof.
     All calculations  under this Section 6(d) shall be made to the nearest cent
     or to the nearest one-hundredth of a share, as the case may be.

          (e)  The Company may retain a firm of independent  public  accountants
     of  recognized  standing  selected  by the  Board  (who may be the  regular
     accountants  employed by the Company) to make any  computation  required by
     this Section 6.

          (f)  In the event that at any time, as a result of an adjustment  made
     pursuant to Section  6(a),  (b) or (c) of this  Warrant,  the Holder of any
     Warrant  thereafter  shall  become  entitled  to receive  any shares of the
     Company,  other  than  Common  Stock,  thereafter  the number of such other
     shares so  receivable  upon  exercise  of any  Warrant  shall be subject to
     adjustment from time to time in a manner and on terms as nearly  equivalent
     as practicable to the provisions with respect to the Common Stock contained
     in Sections 6(a) through (h), inclusive, of this Warrant.

          (g)  For purposes of any computation respecting consideration received
     pursuant to this Section 6, the following shall apply:

               A.   in the case of the  issuance  of shares of Common  Stock for
          cash,  the  consideration  shall be the amount of such cash,  provided

                                       6
<PAGE>

          that in no case  shall  any  deduction  be made  for any  commissions,
          discounts  or  other   expenses   incurred  by  the  Company  for  any
          underwriting of the issue or otherwise in connection therewith;

               B.   in the case of the  issuance of shares of Common Stock for a
          consideration  in whole or in part other than cash, the  consideration
          other than cash shall be deemed to be the fair market value thereof as
          determined  in good  faith by the Board of  Directors  of the  Company
          (irrespective   of   the   accounting   treatment   thereof),    whose
          determination shall be conclusive; and

               C.   in the  case  of the  issuance  of  securities  convertible,
          exchangeable or exercisable for shares of Common Stock,  the aggregate
          consideration   received   therefor   shall  be   deemed   to  be  the
          consideration  received  by the  Company  for  the  issuance  of  such
          securities plus the additional  minimum  consideration,  if any, to be
          received by the Company upon the  conversion or exchange  thereof (the
          consideration  in each  case to be  determined  in the same  manner as
          provided in clauses (A) and (B) of this Subsection).

          (h)  Notwithstanding  the foregoing,  no adjustment  shall be effected
     due to, or as a result of, any Permitted Issuances.

     7.   REGISTRATION  RIGHTS.  The  Warrant  Stock  shall be  entitled  to the
registration  rights  described in Section 8 of the Letter and subsequent to the
first closing,  in Section 5(b) the Placement Agent Agreement to be entered into
by Casimir L.P. and the Company.

     8.   OFFICER'S  CERTIFICATE.   Whenever  the  Exercise  Price(s)  shall  be
adjusted as required by the provisions of Section 6 of this Warrant, the Company
shall  forthwith file in the custody of its Secretary or an Assistant  Secretary
at its principal  office and with its stock transfer agent, if any, an officer's
certificate  showing the adjusted  Exercise  Price(s) and the adjusted number of
shares of Common Stock  issuable upon  exercise of each  Warrant,  determined as
herein  provided,  setting forth in reasonable  detail the facts  requiring such
adjustment,  including a statement of the number of additional  shares of Common
Stock, if any, and such other facts as shall be necessary to show the reason for
and the manner of computing such  adjustment.  Each such  officer's  certificate
shall be forwarded by certified mail to Holder as provided in Section 13

     9.   NOTICES  TO  WARRANT  HOLDERS.  So  long  as  this  Warrant  shall  be
outstanding,  (1) if the Company shall pay any dividend or make any distribution
upon Common  Stock,  or (2) if the Company  shall offer to the holders of Common
Stock for  subscription  or purchase by them any share of any class or any other
rights, or (3) if any capital reorganization of the Company, reclassification of
the capital stock of the Company, consolidation or merger of the Company with or
into another entity,  tender offer  transaction for the Company's  Common Stock,
sale, lease or transfer of all or  substantially  all of the property and assets
of the Company, or voluntary or involuntary dissolution,  liquidation or winding
up of the  Company  shall  be  effected,  or (4) if  the  Company  shall  file a
registration statement under the Securities Act of 1933, as amended (the "Act"),
on any form other  than on Form S-4 or S-8 or any  successor  form,  then in any
such case, the Company shall cause to be mailed by certified mail to the Holder,
at least  fifteen days prior to the date  specified in clauses (1),  (2), (3) or
(4),  as the  case  may be,  of  this  Section  9 a  notice  containing  a brief
description of the proposed action and stating the date on which (i) a record is

                                       7
<PAGE>

to be taken for the purpose of such dividend,  distribution  or rights,  or (ii)
such  reclassification,  reorganization,  consolidation,  merger,  tender  offer
transaction,  conveyance,  lease,  dissolution,  liquidation or winding up is to
take  place and the  date,  if any is to be fixed,  as of which the  holders  of
Common  Stock  or  other   securities  shall  receive  cash  or  other  property
deliverable upon such reclassification,  reorganization,  consolidation, merger,
conveyance,  dissolution,  liquidation or winding up, or (iii) such registration
statement is to be filed with the Securities and Exchange Commission.

     10.  RECLASSIFICATION,   REORGANIZATION   OR   MERGER.   In   case  of  any
reclassification,  capital  reorganization or other change of outstanding shares
of Common Stock of the Company, or in case of any consolidation or merger of the
Company with or into another  corporation (other than a merger with a subsidiary
in which merger the Company is the continuing or surviving corporation and which
does not result in any reclassification,  capital reorganization or other change
of  outstanding  shares of Common Stock of the class  issuable  upon exercise of
this  Warrant)  or  in  case  of  any  sale,  lease  or  conveyance  of  all  or
substantially all of the assets of the Company,  or in the case of any statutory
exchange of securities with another corporation (including any exchange effected
in  connection  with a merger  of a third  corporation  into the  Company),  the
Company shall,  as a condition  precedent to such  transaction,  cause effective
provisions to be made so that (i) the Holder shall have the right  thereafter by
exercising this Warrant,  to purchase the kind and amount of shares of stock and
other  securities and property  receivable upon such  reclassification,  capital
reorganization  and other change,  consolidation,  merger,  sale,  conveyance or
statutory  exchange  by a holder of the number of shares of Common  Stock  which
could have been  purchased  upon exercise of this Warrant  immediately  prior to
such  reclassification,  change,  consolidation,  merger, sale,  conveyance,  or
statutory  exchange and (ii) the successor or acquiring  entity shall  expressly
assume  the  due and  punctual  observance  and  performance  of each  covenant,
agreement, obligation and condition of this Warrant to be performed and observed
by Company and all  obligations  and  liabilities  hereunder  (including but not
limited to the  provisions  of Section 6 regarding the increase in the number of
shares of Warrant Stock  potentially  issuable  hereunder).  Any such  provision
shall include  provision for adjustments  which shall be as nearly equivalent as
possible  to  the  adjustments  provided  for in  this  Warrant.  The  foregoing
provisions   of  this   Section   10  shall   similarly   apply  to   successive
reclassifications, capital reorganizations and changes of shares of Common Stock
and to successive  consolidations,  mergers, sales or conveyances.  In the event
that in connection  with any such capital  reorganization  or  reclassification,
consolidation, merger, sale, conveyance or statutory exchange, additional shares
of Common  Stock  shall be  issued  in  exchange,  conversion,  substitution  or
payment,  in whole in part,  for a security  of the  Company  other than  Common
Stock, any such issue shall be treated as an issuance of Common Stock covered by
the  provisions of Section 6 of this Warrant.  Notice of any such event shall be
mailed by certified mail to the Holders of the Warrants no less than thirty (30)
days prior to such event.  A sale of all or  substantially  all of the Company's
assets for a consideration  consisting primarily of securities shall be deemed a
consolidation or merger for the foregoing purposes.

     11.  TRANSFER TO COMPLY WITH THE  SECURITIES  ACT OF 1933.  This Warrant or
the Warrant Stock or any other security issued or issuable upon exercise of this
Warrant may not be sold or otherwise disposed of except as follows:

          (i)  to a person who, in the  opinion of counsel for the  Company,  or
     counsel for the Holder who is reasonably  acceptable  to the Company,  is a

     person to whom this  Warrant or Warrant  Stock may  legally be  transferred
     without registration and without the delivery of a current prospectus under
     the Act with respect  thereto and then only against receipt of an agreement
     of such  person to  comply  with the  provisions  of this  Section  11 with
     respect  to any  resale  or  other  disposition  of such  securities  which
     agreement  shall be  satisfactory  in form and substance to the Company and
     its counsel; or

          (ii) To any person upon  delivery  of a  prospectus  then  meeting the
     requirements  of the Act  relating  to  such  securities  and the  offering
     thereof for such sale or disposition.

          (iii) Notwithstanding (i) and (ii)  above,  The Company  approves  the
     transfer of this Warrant to affiliates of the Holders.

          (iv) The  registration  rights  contained in Section 7 of this Warrant
     may be assigned in full by a Holder in connection with the transfer of this
     Warrant or any other Warrant stock.
