Exhibit 4.3



                           APPLIED DNA SCIENCES, INC.

          WARRANT AGREEMENT,  dated _________,  2005 (the  "Agreement"),  by and
between Applied DNA Sciences,  Inc., a Nevada  corporation (the "Company"),  and
__________________  the holder of one (1) unit of the Company sold in connection
with the Company's Private Placement (as defined below) (individually a "Holder"
and collectively with the holders of other Units, the "Holders").

          WHEREAS, the Company has proposed to offer,  pursuant to the Company's
private placement offering (the "Private Placement"),  a maximum of 120 units of
the Company  (the  "Units"),  each Unit  consisting  of (i) a $50,000  principal
amount Secured  Convertible  10% Promissory  Note, and (ii) warrants to purchase
100,000 shares of the Company's  common stock,  exercisable for a period of five
years at a price of $0.75 per share;

          WHEREAS, purchasers of the Units have been issued Warrant Certificates
evidencing the Warrants; and

          WHEREAS, the Warrant  Certificates  incorporate by reference the terms
of this Warrant Agreement.

          NOW,  THEREFORE,  in  consideration  of the  premises  and the  mutual
covenants contained herein, the Company and the Holder hereby agree as follows:

          1. Exercise of Warrant. This warrant (the "Warrant") shall entitle the
Holder  thereof to purchase an aggregate of 100,000 shares of Common Stock at an
exercise  price of $0.75 (the "Exercise  Price") per share.  The Warrants may be
exercised in whole or in part at any time or from time to time during the period
commencing on 2005 and expiring at 5:00 p.m., New York City time, on , 2010 (the
"Exercise Term"),  or if 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, by presentation  and surrender of the Warrant
Certificate  evidencing  the  Warrant  to be  exercised  to the  Company  at its
principal  office or at the office of its stock transfer agent, if any, with the
Exercise  Form annexed  hereto duly executed and  accompanied  by payment of the
Exercise Price for the number of shares specified in such form. . If any Warrant
should be  exercised  in part only,  the Company  shall,  upon  surrender of the
Warrant  Certificates  for  cancellation  and  presentment of the Exercise Form,
execute and deliver new a Warrant  Certificate or Certificates,  as the case may
be,  evidencing  the rights of the Holder thereof to purchase the balance of the
shares  purchasable  thereunder.  Upon  receipt  by  the  Company  of a  Warrant
Certificate at its office,  or by the stock transfer agent of the Company at its
office,  in proper form for exercise and accompanied by the appropriate  payment
for the shares of Common Stock  underlying the Warrants (the "Warrant  Shares"),
the Holder  shall be deemed to be the holder of record of such  Warrant  Shares,
notwithstanding  that the stock  transfer  books of the  Company  shall  then be
closed or that  certificates  representing such Warrant Shares shall not then be
actually  delivered to the Holder.  Certificates for the Warrant Shares shall be
delivered to the Holder within a reasonable  time  following the exercise of the
Warrants in accordance with the foregoing.


          2. Alternative Exercise  Provisions.  Anything contained herein to the
contrary notwithstanding,  provided that the shares underlying this Warrant have
been registered,  the Holder, at his option, may exercise the Warrants, in whole
or in part, during the Exercise Term by delivering to the Company a confirmation
slip issued by a brokerage firm that is a member of the National  Association of
Securities  Dealers,  Inc.  with  respect to the sale of those number of Warrant
Shares for which the  Warrants  are being  exercised,  and,  in such  case,  the
Company  shall  deliver   certificates   representing  such  Warrant  Shares  on
settlement  date at the office of the  Company's  stock  transfer  agent against
payment for such Warrant Shares by such  brokerage firm or its clearing  broker,
made  payable  to the  Company  or made  payable  to the order of the Holder and
endorsed by the Holder to the Company.

          3.  Reservation and Listing of Shares.  The Company hereby agrees that
at all times there shall be reserved for issuance and delivery  upon exercise of
the Warrants, such number of shares of its Common Stock as shall be required for
issuance and delivery  upon  exercise of the  Warrants.  As long as the Warrants
shall be outstanding, the Company shall use its best efforts to cause all shares
of Common Stock  issuable  upon the exercise of the Warrants to be listed on the
Over The Counter Bulletin Board or on Nasdaq or a national securities  exchange,
if such shares of Common Stock, as a class, are theretofore so listed.

          4.  Fractional  Shares.  No  tractional  shares or scrip  representing
fractional  shares  shall be  issued  upon the  exercise  of the  Warrants.  Any
fraction of a share called for upon any exercise  hereof shall be canceled.  The
Holder,  by his  acceptance  hereof,  expressly  waives any right to receive any
fractional share of stock or fractional Warrant upon exercise of the Warrants.

          5. Exchange. Transfer. Assignment or Loss of Warrant. The Warrants are
exchangeable,  without expense,  at the option of the Holder,  upon presentation
and  surrender  of the  Warrant  Certificates  evidencing  such  Warrants to the
Company at its office or at the office of its stock transfer  agent, if any, for
other  Warrants  of  different  denominations  entitling  the Holder  thereof to
purchase  in the  aggregate  the same  number of  shares of Common  Stock as are
purchasable thereunder at the same respective Exercise Price. Subject to Section
10 hereof,  upon  surrender  of the Warrant  Certificates  to the Company at its
principal  office or at the office of its stock transfer  agent,  if any, with a
duly executed  Assignment  Form which is annexed hereto and funds  sufficient to
pay the  applicable  transfer tax, if any, the Company  shall,  without  charge,
execute and deliver new Warrant  Certificates  in the name of the assignee named
in such  instrument of assignment  and the original  Warrant  Certificate  shall
promptly  be  canceled.  The  Warrants  may be  divided or  combined  with other
Warrants  which  carry  the  same  rights  upon   presentation  of  the  Warrant
Certificate  evidencing  such  Warrants  at the office of the  Company or at the
office of its stock  transfer  agent,  if any,  together  with a written  notice
signed by the Holder hereof  specifying the names and denominations in which new
Warrant  Certificates are to be issued.  Upon receipt by the Company of evidence
satisfactory  to it of  the  loss,  theft,  destruction  or  mutilation  of  the
Warrants,  and,  in the  case of  loss,  theft  or  destruction,  of  reasonably
satisfactory  indemnification,  and  upon  surrender  and  cancellation  of  the
Warrants,  if  mutilated,  the  Company  will  execute  and  deliver new Warrant
Certificates  of like tenor and date.  Any such new Warrant  Certificates,  when
executed and delivered, shall constitute an additional contractual obligation on
the  part of the  Company,  whether  or not the  Warrant  Certificates  so lost,
stolen, destroyed, or mutilated shall be at any time enforceable by anyone

                                       2

          6. Rights of the Holder.  The Holder shall not, by virtue  hereof,  be
entitled to any rights of a  shareholder  of the Company  until  exercise of any
Warrants.

          7. Adjustments of Purchase Price and Number of Shares.

          (a) Subdivision and Combination. In case the Company shall at any time
subdivide  or combine  the  outstanding  shares of Common  Stock by way of stock
split,  reverse stock split or the like, the Exercise  Prices shall forthwith be
proportionately increased or decreased.

          (b)  Adjustment  in Number of  Shares.  Upon  each  adjustment  of the
Exercise  Price  pursuant  to the  provisions  of this  Section 7, the number of
Shares  issuable  upon the  exercise  of each  Warrant  shall be adjusted to the
nearest full Share by multiplying a number equal to the Exercise Price in effect
immediately  prior to such  adjustment  by the  number of Shares  issuable  upon
exercise of the Warrants  immediately  prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.

          (c)  Reclassification.  Consolidation.  Merger.  etc.  In  case of any
reclassification or change of the outstanding shares of Common Stock (other than
a change in par value to no par value,  or from no par value to par value, or as
a result of a subdivision or combination),  or in the case of any  consolidation
of the Company with, or merger of the Company into,  another  corporation (other
than a consolidation or merger in which the Company is the surviving corporation
and which does not result in any  reclassification  or change of the outstanding
shares  of  Common  Stock,  except a  change  as a result  of a  subdivision  or
combination of such shares or a change in par value,  as  aforesaid),  or in the
case of a sale or conveyance to another corporation of all or a substantial part
of the property of the Company,  the Holder shall  thereafter  have the right to
purchase  the kind and  number  of shares  of stock  and  other  securities  and
property receivable upon such reclassification,  change, consolidation,  merger,
sale or conveyance as if the Holder were the owner of the shares of Common Stock
underlying the Warrants immediately prior to any such events at a price equal to
the product of (x) the number of shares  issuable  upon exercise of the Warrants
and (y) the Exercise  Price in effect  immediately  prior to the record date for
such reclassification,  change, consolidation,  merger, sale or conveyance as if
such Holder had exercised the Warrants.

          (d)  Dividends  and Other  Distributions  with Respect to  Outstanding
Securities.  In the  event  that the  Company  shall  at any  time  prior to the
exercise of all Warrants  declare a dividend  (other than a dividend  consisting
solely of shares of Common Stock or a cash dividend or distribution  payable out
of current or retained earnings) or otherwise distribute to its shareholders any
monies, assets, property,  rights, evidences of indebtedness,  securities (other
than shares of Common Stock), whether issued by the Company or by another person
or entity,  or any other thing of value, the Holder of the unexercised  Warrants
shall thereafter be entitled, in addition to the shares of Common Stock or other
securities  receivable upon the exercise thereof, to receive,  upon the exercise
of such  Warrants,  the same  monies,  property,  assets,  rights,  evidences of
indebtedness,  securities  or any other thing of value that they would have been
entitled to receive at the time of such dividend or distribution. At the time of
any such dividend or distribution,  the Company shall make appropriate  reserves
to ensure the timely performance of the provisions of this Subsection 7(d).

                                       3

          (e) Warrant  Certificate After Adjustment.  Irrespective of any change
pursuant to this Section 7 in the Exercise Price or in the number, kind or class
of shares or other securities or other property  obtainable upon exercise of the
Warrants,  the Warrants may continue to express as the Exercise Price and as the
number of shares  obtainable upon exercise,  the same price and number of shares
as are stated herein.

          (f)  Statement of  Calculation.  Whenever the Exercise  Price shall be
adjusted  pursuant  to the  provisions  of this  Section  7, the  Company  shall
forthwith  file at its  principal  office,  a statement  signed by an  executive
officer of the Company  specifying  the adjusted  Exercise  Price  determined as
above provided in such section.  Such statement shall show in reasonable  detail
the  method  of  calculation  of such  adjustment  and the facts  requiring  the
adjustment and upon which the calculation is based.  The Company shall forthwith
cause a notice setting forth the adjusted Exercise Price to be sent by certified
mail, return receipt requested, postage prepaid, to the Holder.

          8. Call Rights of Company. Upon 10 days written notice the Company may
call the Warrant for  redemption by the Company at any time after the underlying
Common Stock (i) has been  registered  for public sale and (ii) has traded at or
above $1.25 per share on 20  consecutive  trading  days and  providing  that the
underlying Registration has and is effective during such time period.

          9. Definition of "Common Stock." For the purpose of the Warrants,  the
term "Common Stock" shall mean, in addition to the class of stock  designated as
the Common Stock,  $.001 par value, of the Company on the date hereof, any class
of stock resulting from successive  changes or  reclassifications  of the Common
Stock  consisting  solely of changes  in par value,  or from par value to no par
value,  or from no par value to par  value.  If at any  time,  as a result of an
adjustment  made pursuant to one or more of the  provisions of Section 7 hereof,
the shares of stock or other securities or property  obtainable upon exercise of
the Warrants shall include securities of the Company other than shares of Common
Stock or securities of another  corporation,  then thereafter the amount of such
other  securities so obtainable shall be subject to adjustment from time to time
in a manner and upon terms as nearly equivalent as practicable to the provisions
with  respect  to Common  Stock  contained  in  Section  7 hereof  and all other
provisions  of the  Warrants  with  respect to Common  Stock shall apply on like
terms to any such other shares or other securities.

          10.  Registration Under the Securities Act of 1933. The Warrant Shares
issuable upon exercise of the Warrants are subject to the Company's registration
obligations  as set  forth  in a  Registration  Rights  Agreement  of even  date
herewith,  the terms of which are  incorporated  by reference  into this Warrant
Agreement as if such terms are set forth at length herein.

          11. Transfer to Comply with the Act.  Neither Warrants nor the Warrant
Shares nor any other  security  issued or issuable upon exercise of the Warrants
may be sold or otherwise disposed of except as follows:

                                       4

          (a) to a person who, in the opinion of counsel for the  Company,  is a
person to whom the Warrants or Warrant Shares 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 a letter from such person in
which such person represents that he is acquiring the Warrants or Warrant Shares
for his own account for investment  purposes and not with a view to distribution
and provides any other information and representations  required by the Company,
and in which such person agrees to comply with the provisions of this Section 10
with respect to any resale or other disposition of such securities; or

          (b) 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.

          12. Notices to Warrant  Holders.  Nothing  contained in this Agreement
shall be construed as conferring upon the Holder or Holders the right to vote or
to consent or to receive  notice as a shareholder  in respect of any meetings of
shareholders for the election of directors or any other matter, or as having any
rights  whatsoever as a shareholder  of the Company.  If,  however,  at any time
prior to the expiration of the Warrants and their exercise, any of the following
events shall occur:

          (a) The  Company  shall take a record of the  holders of its shares of
Common  Stock  for the  purpose  of  entitling  them to  receive a  dividend  or
distribution  payable otherwise than in cash, or a cash dividend or distribution
payable otherwise than out of current or retained earnings,  as indicated by the
accounting  treatment  of such  dividend  or  distribution  on the  books of the
Company; or

          (b) The Company shall offer to all the holders of its Common Stock any
additional shares of capital stock of the Company or securities convertible into
or  exchangeable  for shares of capital  stock of the  Company,  or any warrant,
right or option to subscribe therefor; or

          (c) A  dissolution,  liquidation  or winding up of the Company  (other
than  in  connection  with  a  consolidation  or  merger)  or a  sale  of all or
substantially all of its property, assets and business shall be proposed; or

          (d) There shall be any capital  reorganization or  reclassification of
the capital stock of the Company, or consolidation or merger of the Company with
another entity,  then, in anyone or more of said events,  the Company shall give
written  notice of such event at least fifteen (15) days prior to the date fixed
as a record date or the date of closing the transfer books for the determination
of the  shareholders  entitled to such  dividend,  distribution,  convertible or
exchangeable securities or subscription rights, warrants or options, or entitled
to vote on such  proposed  dissolution,  liquidation,  winding up or sale.  Such
notice shall specify such record date or the date of closing the transfer books,
as the case may be.  Failure to give such notice or any defect therein shall not
affect the validity of any action taken in connection  with the  declaration  or
payment of any such dividend or distribution, or the issuance of any convertible
or exchangeable  securities or subscription rights,  warrants or options, or any
proposed dissolution, liquidation, winding up or sale.
