                                  Avitar, Inc.

               Warrant for the Purchase of Shares of Common Stock,
                            par value $0.01 per Share


No. W-G1                                                       4,666,666 Shares
Issuance Date:  August 13, 2003

     THIS CERTIFIES that, for value received,  Gryphon Master Fund,  L.P., whose
address is 500 Crescent Court, Suite 270, Dallas, Texas 75201 (the "Holder"), is
entitled to subscribe for and purchase from Avitar, Inc., a Delaware corporation
(the  "Company"),  upon the terms and  conditions  set forth  herein,  4,666,666
shares  of the  Company's  Common  Stock,  par value  $0.01  per share  ("Common
Stock"),  at a price of $0.01 per share (the "Exercise  Price").  As used herein
the term "this Warrant" shall mean and include this Warrant and any Common Stock
or Warrants  hereafter  issued as a  consequence  of the exercise or transfer of
this Warrant in whole or in part.

     The number of shares of Common Stock issuable upon exercise of the Warrants
(the  "Warrant  Shares") may be adjusted  from time to time as  hereinafter  set
forth.  The  Warrant  Shares are  entitled to the  benefits,  and subject to the
obligations,  set forth in the Registration Rights Agreement between the Company
and the Holder dated concurrently herewith.

     1. Exercise Period.  This Warrant may be exercised at any time or from time
to time during the period  commencing  on the  Issuance  Date and ending at 5:00
P.M. Eastern time on August 13, 2008 (the "Exercise Period").

     2. Procedure for Exercise; Effect of Exercise.

     (a) Cash Exercise.  This Warrant may be exercised,  in whole or in part, by
the Holder during normal  business hours on any business day during the Exercise
Period by (i) the  presentation  and surrender of this Warrant to the Company at
its principal  office along with a duly executed Notice of Exercise (in the form
attached  to this  Agreement)  specifying  the  number of  Warrant  Shares to be
purchased, and (ii) delivery of payment to the Company of the Exercise Price for
the number of Warrant Shares  specified in the Notice of Exercise by cash,  wire
transfer of  immediately  available  funds to a bank  account  specified  by the
Company, or by certified or bank cashier's check.

     (b)  Cashless  Exercise.  This  Warrant may also be exercised by the Holder
through a cashless exercise, as described in this Section 2(b). This Warrant may
be exercised, in whole or in part, by the Holder during normal business hours on
any business day during the Exercise Period by the presentation and surrender of
this Warrant to the Company at its  principal  office along with a duly executed
Notice of Exercise specifying the number of Warrant Shares to be applied to such
exercise.  The number of Warrant  Shares to be delivered  upon  exercise of this
Warrant  pursuant to this Section 2(b) shall equal the value of this Warrant (or
the portion thereof being canceled)  computed as of the date of delivery of this
Warrant to the Company using the following formula:

                  X =          Y(A-B)
                                 A

     Where:

     X = the number of shares of Common  Stock to be issued to Holder under this
Section 2(b);

     Y = the number of Warrant  Shares  identified  in the Notice of Exercise as
being applied to the subject exercise;

     A = the Current Market Price on such date; and

     B = the Exercise Price on such date

For  purposes of this Section  2(b),  the  "Current  Market  Price" per share of
Common Stock on any date shall be deemed to be the volume weighted average price
of a single  share of Common  Stock for the ten (10)  consecutive  trading  days
immediately  preceding  the date in question as reported on the  American  Stock
Exchange.  If on any such dates the Common  Stock is not listed or  admitted  to
trading on the American Stock Exchange or any other national securities exchange
and is not  quoted by NASDAQ or any  similar  organization,  the fair value of a
share of Common Stock on such date,  as determined in good faith by the board of
directors  of the  Company,  whose  determination  shall  be  conclusive  absent
manifest error, shall be used.

     The Company  acknowledges  and agrees  that this  Warrant was issued on the
Issuance Date.  Consequently,  the Company  acknowledges and agrees that, if the
Holder  conducts a cashless  exercise  pursuant to this Section 2(b), the period
during  which the  Holder  held  this  Warrant  may,  for  purposes  of Rule 144
promulgated under the Securities Act of 1933, as amended (the "Securities Act"),
be  "tacked" to the period  during  which the Holder  holds the  Warrant  Shares
received upon such cashless exercise.

     (c) Effect of  Exercise.  Upon receipt by the Company of this Warrant and a
Notice of  Exercise,  together  with proper  payment of the Exercise  Price,  as
provided in this Section 2, the Company agrees that such Warrant Shares shall be
deemed to be issued to the Holder as the record holder of such Warrant Shares as
of the close of business on the date on which this Warrant has been  surrendered
and  payment  has been  made for such  Warrant  Shares in  accordance  with this
Agreement  and the  Holder  shall be  deemed  to be the  holder of record of the
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.  A  stock  certificate  or
certificates for the Warrant Shares specified in the Notice of Exercise shall be
delivered  to the Holder as promptly  as  practicable,  and in any event  within
seven (7) business days, thereafter. The stock certificate(s) so delivered shall
be in any such denominations as may be reasonably specified by the Holder in the
Notice of  Exercise.  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 right of the Holder to purchase the balance
of the Warrant Shares subject to purchase hereunder.

     3. Registration of Warrants; Transfer of Warrants. Any Warrants issued upon
the transfer or exercise in part of this Warrant  shall be numbered and shall be
registered  in a Warrant  Register  as they are  issued.  The  Company  shall be
entitled to treat the registered  holder of any Warrant on the Warrant  Register
as the  owner  in fact  thereof  for all  purposes  and  shall  not be  bound to
recognize  any  equitable  or other claim to or interest in such  Warrant on the
part of any  other  person,  and shall not be  liable  for any  registration  or
transfer of Warrants  which are  registered or to be registered in the name of a
fiduciary  or the nominee of a fiduciary  unless made with the actual  knowledge
that a fiduciary or nominee is committing a breach of trust in  requesting  such
registration  or  transfer,  or with  the  knowledge  of  such  facts  that  its
participation  therein amounts to bad faith.  This Warrant shall be transferable
only on the books of the Company  upon  delivery  thereof  duly  endorsed by the
Holder or by its duly authorized  attorney or representative,  or accompanied by
proper  evidence of  succession,  assignment,  or authority to transfer.  In all
cases of transfer by an attorney,  executor,  administrator,  guardian, or other
legal representative,  duly authenticated evidence of his or its authority shall
be produced.  Upon any registration of transfer, the Company shall deliver a new
Warrant  or  Warrants  to the  person  entitled  thereto.  This  Warrant  may be
exchanged,  at the option of the Holder thereof,  for another Warrant,  or other
Warrants  of  different  denominations,  of like tenor and  representing  in the
aggregate the right to purchase a like number of Warrant Shares,  upon surrender
to the Company or its duly authorized agent.

     4.  Restrictions  on Transfer.  (a) The Holder,  as of the date of issuance
hereof, represents to the Company that such Holder is acquiring the Warrants for
its own account for investment  purposes and not with a view to the distribution
thereof or of the Warrant Shares.  Notwithstanding  any provisions  contained in
this Warrant to the contrary,  this Warrant and the related Warrant Shares shall
not be transferable  except  pursuant to the proviso  contained in the following
sentence or upon the  conditions  specified in this Section 4, which  conditions
are intended,  among other things,  to insure  compliance with the provisions of
the Securities  Act and applicable  state law in respect of the transfer of this
Warrant or such Warrant Shares.  The Holder by acceptance of this Warrant agrees
that the Holder will not  transfer  this Warrant or the related  Warrant  Shares
prior to delivery to the Company of an opinion of the Holder's  counsel (as such
opinion  and such  counsel  are  described  in  Section  4(b)  hereof)  or until
registration  of such  Warrant  Shares  under  the  Securities  Act  has  become
effective or after a sale of such Warrant or Warrant Shares has been consummated
pursuant to Rule 144 or Rule 144A under the Securities Act;  provided,  however,
that the Holder may freely transfer this Warrant or such Warrant Shares (without
delivery to the Company of an opinion of  Counsel)  (i) to one of its  nominees,
affiliates  or a nominee  thereof,  (ii) to a  pension  or  profit-sharing  fund
established  and  maintained  for  its  employees  or for the  employees  of any
affiliate,  (iii)  from  a  nominee  to any of  the  aforementioned  persons  as
beneficial owner of this Warrant or such Warrant Shares,  or (iv) to a qualified
institutional  buyer,  so long as such transfer is effected in  compliance  with
Rule 144A under the Securities Act.

     (b) The Holder, by its acceptance hereof, agrees that prior to any transfer
of this  Warrant or of the related  Warrant  Shares  (other than as permitted by
Section 4(a) hereof or pursuant to a registration under the Securities Act), the
Holder will give written  notice to the Company of its  intention to effect such
transfer,  together  with an opinion of such  counsel for the Holder as shall be
reasonably  acceptable to the Company,  to the effect that the proposed transfer
of this Warrant and/or such Warrant Shares may be effected without  registration
under the  Securities  Act.  Upon  delivery  of such  notice and  opinion to the
Company,  the Holder  shall be  entitled to transfer  this  Warrant  and/or such
Warrant Shares in accordance with the intended  method of disposition  specified
in the notice to the Company.

     (c) Each stock certificate representing Warrant Shares issued upon exercise
or exchange of this Warrant shall bear the  following  legend unless the opinion
of counsel referred to in Section 4(b) states such legend is not required:

"THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES  ACT OF 1933 AND MAY NOT BE  TRANSFERRED  EXCEPT UPON DELIVERY TO THE
CORPORATION  OF AN OPINION OF COUNSEL  SATISFACTORY  IN FORM AND SUBSTANCE TO IT
THAT SUCH TRANSFER WILL NOT VIOLATE THE SECURITIES ACT OF 1933, AS AMENDED."

The Holder understands that the Company may place, and may instruct any transfer
agent or depository for the Warrant Shares to place, a stop transfer notation in
the securities records in respect of the Warrant Shares.

     5.  Reservation  of  Shares.  The  Company  shall at all times  during  the
Exercise  Period  reserve and keep  available out of its authorized and unissued
Common Stock, solely for the purpose of providing for the exercise of the rights
to purchase all Warrant Shares granted pursuant to the Warrants,  such number of
shares of Common Stock as shall, from time to time, be sufficient therefor.  The
Company covenants that all shares of Common Stock issuable upon exercise of this
Warrant,  upon receipt by the Company of the full Exercise Price  therefor,  and
all shares of Common Stock  issuable upon  conversion of this Warrant,  shall be
validly issued, fully paid, non-assessable, and free of preemptive rights.

     6. Adjustments. The number of shares of Common Stock issuable upon exercise
of the Warrants shall be adjusted from time to time as follows:

     (a) (i) In the event that the  Company  shall (A) pay a dividend  or make a
distribution,  in shares of Common  Stock,  on any class of capital stock of the
Company or any  subsidiary  which is not directly or indirectly  wholly owned by
the Company,  (B) split or subdivide its outstanding Common Stock into a greater
number of shares,  or (C) combine its  outstanding  Common  Stock into a smaller
number of  shares,  then in each such case the  number of shares  issuable  upon
exercise  of this  Warrant  shall be  adjusted  so that the  Holder of a Warrant
thereafter  surrendered  for exercise shall be entitled to receive the number of
shares of Common Stock that such Holder  would have owned or have been  entitled
to receive after the  occurrence of any of the events  described  above had such
Warrant been exercised  immediately  prior to the  occurrence of such event.  An
adjustment  made  pursuant  to  this  Section  6(a)(i)  shall  become  effective
immediately  after the close of  business  on the  record  date in the case of a
dividend or  distribution  (except as provided in Section  6(e) below) and shall
become effective  immediately  after the close of business on the effective date
in the case of such subdivision, split or combination, as the case may be.

     (ii) In the  event  that,  at any time as a result  of an  adjustment  made
pursuant  to  Section  6(a)(i)  above,  the  Holder  of any  Warrant  thereafter
surrendered  for  exercise  shall  become  entitled to receive any shares of the
Company  other than shares of the Common  Stock,  thereafter  the number of such
other shares so receivable upon exercise of any such 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
Section 6(a)(i) above.

     (b) In case of any  reclassification  of the Common  Stock (other than in a
transaction to which Section 6(a)(i) applies),  any consolidation of the Company
with,  or merger of the Company into,  any other  entity,  any merger of another
entity  into the  Company  (other  than a merger  that  does not  result  in any
reclassification,  conversion, exchange or cancellation of outstanding shares of
Common Stock of the Company),  any sale or transfer of all or substantially  all
of the assets of the Company or any compulsory share exchange, pursuant to which
share  exchange  the Common Stock is converted  into other  securities,  cash or
other property, then lawful provision shall be made as part of the terms of such
transaction  whereby  the Holder of a Warrant  then  outstanding  shall have the
right  thereafter,  during the period  such  Warrant  shall be  exercisable,  to
exercise such Warrant only for the kind and amount of securities, cash and other
property  receivable upon the  reclassification,  consolidation,  merger,  sale,
transfer or share  exchange by a holder of the number of shares of Common  Stock
of the  Company  into  which a Warrant  might  have been  able to  exercise  for
immediately prior to the reclassification, consolidation, merger, sale, transfer
or share  exchange  assuming that such holder of Common Stock failed to exercise
rights of  election,  if any,  as to the kind or amount of  securities,  cash or
other property  receivable  upon  consummation  of such  transaction  subject to
adjustment as provided in Section 6(a) above  following the date of consummation
of such  transaction.  The provisions of this Section 6(b) shall similarly apply
to successive  reclassifications,  consolidations,  mergers, sales, transfers or
share exchanges.

(c)      If:

(i)  the  Company  shall  take any action  which  would  require  an  adjustment
     pursuant to Section 6(a); or

(ii) the Company shall authorize the granting to the holders of its Common Stock
     generally of rights,  warrants or options to subscribe  for or purchase any
     shares of any class or any other rights, warrants or options; or

(iii)there shall be any  reclassification  or change of the Common  Stock (other
     than a subdivision  or  combination  of its  outstanding  Common Stock or a
     change  in par  value) or any  consolidation,  merger  or  statutory  share
     exchange  to which the  Company  is a party and for which  approval  of any
     stockholders of the Company is required,  or the sale or transfer of all or
     substantially all of the assets of the Company; or

(iv) there shall be a  voluntary  or  involuntary  dissolution,  liquidation  or
     winding up of the Company;

then,  the  Company  shall  cause to be filed  with the  transfer  agent for the
Warrants and shall cause to be mailed to each Holder at such Holder's address as
shown on the  books of the  transfer  agent for the  Warrants,  as  promptly  as
possible,  but at  least  30  days  prior  to the  applicable  date  hereinafter
specified,  a notice  stating  (A) the date on which a record is to be taken for
the purpose of such dividend,  distribution  or granting of rights,  warrants or
options, 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,  distribution or rights,
warrants  or  options  are to be  determined,  or (B)  the  date on  which  such
reclassification, change, consolidation, merger, statutory share exchange, sale,
transfer, dissolution, liquidation or winding-up is expected to become effective
or occur,  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 or other property  deliverable  upon such  reclassification,  change,
consolidation,  merger, statutory share exchange,  sale, transfer,  dissolution,
liquidation  or winding up.  Failure to give such  notice or any defect  therein
shall not affect the legality or validity of the  proceedings  described in this
Section 6(c).

     (d) Whenever an  adjustment is made as herein  provided,  the Company shall
promptly  file with the  transfer  agent for the  Warrants a  certificate  of an
officer of the Company  setting forth the  adjustment  and setting forth a brief
statement of the facts requiring such adjustment and a computation  thereof. The
Company shall  promptly  cause a notice of such  adjustment to be mailed to each
Holder.

     (e) In any case in which Section 6(a)  provides  that an  adjustment  shall
become effective immediately after a record date for an event and the date fixed
for such  adjustment  pursuant to Section 6(a) occurs after such record date but
before the  occurrence  of such  event,  the  Company may defer until the actual
occurrence  of such event (i)  issuing to the Holder of any  Warrants  exercised
after such record date and before the  occurrence  of such event the  additional
shares of Common Stock issuable upon such conversion by reason of the adjustment
required  by such  event  over and above the  Common  Stock  issuable  upon such
exercise before giving effect to such adjustment, and (ii) paying to such holder
any amount in cash in lieu of any fraction pursuant to Section 6(f).

     (f) The  Company  shall not be  required  to issue  fractions  of shares of
Common  Stock or other  capital  stock of the Company  upon the exercise of this
Warrant.  If any  fraction of a share would be issuable on the  exercise of this
Warrant (or  specified  portions  thereof),  the  Company  shall  purchase  such
fraction for an amount in cash equal to the same fraction of the Current  Market
Price of such share of Common Stock on the date of exercise of this Warrant.

     7. Transfer Taxes.  The issuance of any shares or other securities upon the
exercise of this Warrant,  and the delivery of certificates or other instruments
representing  such shares or other  securities,  shall be made without charge to
the Holder for any tax or other charge in respect of such issuance.  The Company
shall not,  however,  be required to pay any tax which may be payable in respect
of any transfer  involved in the issue and delivery of any certificate in a name
other than that of the Holder and the Company  shall not be required to issue or
deliver any such certificate  unless and until the person or persons  requesting
the issue 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.

     8. Loss or Mutilation of Warrant.  Upon receipt of evidence satisfactory to
the Company of the loss, theft,  destruction,  or mutilation of any Warrant (and
upon  surrender  of any Warrant if  mutilated),  and upon  reimbursement  of the
Company's reasonable incidental expenses,  the Company shall execute and deliver
to the Holder thereof a new Warrant of like date, tenor, and denomination.

     9. No Rights as a  Stockholder.  The Holder of any Warrant  shall not have,
solely on account of such status,  any rights of a  stockholder  of the Company,
either at law or in equity,  or to any notice of meetings of  stockholders or of
any other proceedings of the Company, except as provided in this Warrant.

     10.  Governing Law. This Warrant shall be construed in accordance  with the
laws of the State of Delaware  applicable to contracts made and performed within
such State, without regard to principles of conflicts of law.

                                      * * *
