                                VOTING SECURITIES

     The Board has fixed the close of business on May 9, 2003 as the record date
(the "Record Date") for determination of stockholders entitled to receive notice
of  and  to  vote  at the  Annual  Meeting  or  any  adjournment  thereof.  Only
stockholders  of record  at the close of  business  on the  Record  Date will be

Preferred  Stock,  of which 7,228 were  shares of Series B  Preferred  Stock and

of Series D Preferred  Stock) and each share of Series B Preferred  Stock on the
election of members of the Board of Directors and other business as may properly
come before the meeting or any adjournments  thereof.  The holders of a majority
of the outstanding  voting shares  constitute a quorum.  Abstentions from voting
and broker  non-votes on a particular  Proposal  will be counted for purposes of
determining  the presence of a quorum but will not be counted as  affirmative or
negative votes on the Proposals.

     As of the Record Date, the directors and executive officers of Avitar as a
group held 5,623,522 voting shares, representing 7.7 % of the shares eligible to
vote at the Annual Meeting. (In addition, also as of the Record Date, beneficial

                         ACTION TO BE TAKEN UNDER PROXY

     All proxies for  stockholders  in the  accompanying  form that are properly
executed and returned will be voted at the Annual  Meeting and any  adjournments
thereof in accordance with any  specifications  thereon or, if no specifications

                                  SOLICITATION

     Avitar will bear the entire cost of the  solicitation  of proxies  from its
stockholders,  including  preparation,  assembly,  printing  and mailing of this
Proxy  Statement,  the proxy card and any  additional  information  furnished to
stockholders.  Copies of  solicitation  materials  will be  furnished  to banks,
brokerage  houses,  fiduciaries  and  custodians  holding in their names  shares
beneficially  owned by others to forward  to such  beneficial  owners.  Original
solicitation  of proxies by mail may be  supplemented  by telephone,  facsimile,
telegram or  personal  solicitation  by  directors,  officers  or other  regular
employees of Avitar. No additional compensation will be paid to such persons for
such   services.   Avitar  may  also  employ  the  services  of  a  professional
solicitation company to assist with solicitation of stockholders;  but as of May
23, 2003 Avitar has not determined to retain a solicitation  company.  If such a
company were subsequently retained, Avitar would bear the entire cost.

BOARD MEETINGS AND COMMITTEES

     The Board held 4 meetings during the fiscal year ended September 30, 2002.

     The  Board  has  two  standing  committees:  the  Audit  Committee  and the
Compensation Committee.  The Board does not have a standing nominating committee
or any committee performing the function of such a committee. During fiscal year
2002,  each  Board  member  attended  at least  75% of the  aggregate  number of
meetings of the Board and the Committee of the Board on which he served.

AUDIT COMMITTEE.

     The Audit  Committee  meets  with the  independent  auditors,  at a minimum
annually,  to review the results of the annual  audit and discuss the  financial
statements; recommends to the Board the independent auditors to be retained; and
receives and considers  the  accountants'  comments as to controls,  adequacy of
staff and management  performance  and  procedures in connection  with audit and
financial   records.   Management  has  primary   responsibility  for  financial
statements  and  the  reporting  process,  including  the  systems  of  internal
controls,  and  has  represented  to the  Audit  Committee  that  Avitar's  2002
consolidated  financial  statements are in accordance  with  generally  accepted
accounting principles.  The Audit Committee,  comprised of Mr. Gordon, Mr. Groth
and  Mr.  McCarthy,  held 2  telephone  meetings  concerning  fiscal  year  2002
(although  both  meetings  were held during the first  quarter after fiscal year
2002).  In addition,  the Audit  Committee  reviewed and approved the  financial
statements  that were included in each of the  quarterly  reports on Form 10-QSB
during the year ended September 30, 2002.

AUDIT COMMITTEE REPORT

     In connection with the fiscal 2002 audit, the Audit Committee has:

- -    reviewed  and  discussed  with  management  Avitar's  audited  consolidated
     financial  statements  included in our annual report on Form 10-KSB for the
     year ended September 30, 2002,

- -    discussed  with BDO  Seidman,  LLP the matters  required to be discussed by
     Statement of Auditing Standards No. 61,

- -    discussed with BDO Seidman,  LLP whether  various other services  performed
     for Avitar during 2002 were  compatible  with BDO Seidman,  LLP maintaining
     its independence, and

- -    received from and discussed with BDO Seidman,  LLP the written  disclosures
     and the letter from BDO Seidman, LLP required by the Independence Standards
     Board Standard No. 1 and discussed with BDO Seidman, LLP its independence.

     Based  on the  review  and  the  discussions  described  above,  the  Audit
Committee  recommended to the Board of Directors  that the audited  consolidated
financial  statements  be included  in our annual  report on Form 10-KSB for the
year ended  September  30,  2002 for filing  with the  Securities  and  Exchange
Commission.

     The Board of Directors has approved a written charter,  a copy of which was
attached to the 2001 Proxy  Statement.  Two members of the Audit  Committee have
been determined to be independent in accordance with the requirements of Section
121(A) of the American Stock Exchange listing standards.

     Fiscal  2002 Audit  Firm Fee  Summary.  During  fiscal  year  2002,  Avitar
retained its  principal  auditor,  BDO Seidman,  LLP to provide  services in the
following categories and amounts:

Audit Fees, including review of quarterly 10-QSB filings...............$106,290
All Other Fees..........................................................$18,100

     The Audit  Committee  has  considered  whether the  provision  of non-audit
services by the Company's  principal  auditor was  compatible  with  maintaining
auditor independence and has determined such services were not incompatible with
maintaining auditor independence.

                               THE AUDIT COMMITTEE
                                 Neil R. Gordon
                                   James Groth
                            Charles R. McCarthy, Jr.

     The Audit Committee Report shall not be deemed incorporated by reference by
any general  statement  incorporating by reference this Proxy Statement into any
filing under the Securities Act of 1933 or under the Securities  Exchange Act of
1934  (together,   the  "Acts"),   except  to  the  extent  Avitar  specifically
incorporates  this  information by reference,  and shall not otherwise be deemed
filed under such Acts.

COMPENSATION COMMITTEE.

     The Compensation  Committee makes  recommendations  to the Board concerning
salaries  and  incentive  compensation,  awards stock  options to employees  and
consultants and otherwise determines compensation levels and performs such other
functions  regarding  compensation as the Board may delegate.  The  Compensation
Committee, comprised of Mr. Gordon, Mr. Groth and Mr. McCarthy, held no meetings
in fiscal year 2002.


DIRECTOR COMPENSATION

     During Fiscal 2002,  in  accordance  with a plan approved by the Company on
September 25, 2001, the Company compensated its non-management  directors with a
$5,000 annual retainer, $1,000 for each board meeting attended and $500 for each
committee   meeting  attended.   In  addition,   this  plan  provides  for  each
non-management  director to be granted  options  covering  100,000 shares of the
Company's  common stock upon initial  election to the Board and 30,000 shares of
the  Company's  common stock for each year in which he/she was selected to serve
as a director.  Under the plan  approved by the Company on  September  25, 2001,
non-management  directors  received  option grants covering 90,000 shares of the
Company's  common stock on March 31, 2002.  These options have an exercise price
of $.76 per share, vest over three years and will expire in March 31, 2012.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities  Exchange Act of 1934 requires the officers
and directors, and persons who own more than 10% of a registered class of equity
securities  to file  reports of  ownership  and  changes in  ownership  with the
Securities and Exchange Commission ("SEC"). Officers, directors and greater than
10% stockholders are required by SEC regulation to furnish Avitar with copies of
all Section 16(a) forms they file.

     Based on its  review of the  copies  of such  forms  received  by it or its
written  representations  from certain reporting  persons,  the Company believes
that,  during Fiscal 2002, all filing  requirements  applicable to its officers,
directors  and  greater  than  ten-percent  shareholders  were  met  except  the
following failures to file timely reports by Section 16(a):

o    One report (Form 4) covering 1 transaction was filed late by Neil Gordon.

o    One  report  (Form 4)  covering  1  transaction  was filed  late by Charles
     McCarthy.

o    One report (Form 4) covering 1 transaction was filed late by James Groth.

o    One  report  (Form  4)  covering  1  transaction  was  filed  late by Peter
     Phildius.

o    One report (Form 4) covering 1 transaction was filed late by Douglas Scott.

o    One  report  (Form  4)  covering  1  transaction  was  filed  late  by  Jay
     Leatherman.



CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     PK&S, a 3.8 % beneficial owner of the Company, provided consulting services
to the Company from  September  1989 to May 1995.  On May 28, 1992,  the Company
entered into a written  consulting  agreement  with PK&S,  which  reflected  the
provisions  of a previous  oral  agreement  approved by the  Company's  Board of
Directors in October 1990.  Pursuant to its arrangement  with the Company,  PK&S
provided the  services of each of Messrs.  Phildius and Scott to the Company for
approximately 20 hours per week.

     On May 19, 1995, the Company's  Consulting Agreement ended and was replaced
by the Employment  Agreements with Messrs.  Phildius and Scott (See  "Employment
Agreements").  As  requested  by Messrs.  Phildius and Scott and approved by the
Company's  Board of  Directors,  the  salary  and  benefits  provided  under the
Employment  Agreements  will be paid  directly  to PK&S.  Under the terms of the
current  employment  agreements  with Peter Phildius and Douglas Scott described
above,  the Company pays their salaries and related  expenses  directly to PK&S.
The aggregate of salaries, fringe benefits and reimbursement of expenses paid to
PK&S by the  Company on behalf of Messrs.  Phildius  and Scott for fiscal  years
2002 and 2001 totaled $448,727 and $467,344 respectively.

     In October 1996, the Company entered into a consulting  agreement with N.R.
Gordon  &  Company,  Inc.  Neil  Gordon,  a  member  of the  Company's  Board of
Directors,  is the  President  of N.R.  Gordon  and  Company,  Inc.  Under  this
agreement,  N.R. Gordon & Company,  Inc. provided financial  consulting services
for which it received  50,000  warrants at an exercise  price of $0.93 per share
and was paid $100.00 per hour for all  services  performed.  In  addition,  N.R.
Gordon & Company,  Inc. was entitled to receive  commissions for certain capital
raising  services.  During Fiscal 1998, the Company canceled the 50,000 warrants
granted to N.R. Gordon & Company in 1996 and replaced them with 100,000 warrants
(of which 50,000 where exercised in October 2001 and the remaining 50,000 do not
expire until 2003) to purchase the Company's Common Stock for $.25 per share. No
services were provided to the Company  under this  Agreement  during Fiscal 1999
and Fiscal  2000.  In March 2001,  the  Company  entered  into a new  consulting
agreement with N.R. Gordon & Company,  Inc. for financial  consulting  services.
Under this new agreement,  N.R. Gordon and Company,  Inc.  received  warrants to
purchase  40,000  shares of the Company's  common stock at an exercise  price of
$.79 per share  until  February  2006 and it is to be paid  $100.00 per hour for
services  rendered to the Company.  Expenses incurred for N.R. Gordon & Company,
Inc. amounted to $4,082 in Fiscal 2002 and $3,617 in Fiscal 2001.

     Management believes each of the foregoing  transactions was entered into on
terms at least as favorable to the Company as could be obtained  from  unrelated
parties negotiating at arms-length.

     Messrs.  Phildius  and Scott are  covered  by  Employment  Agreements  (the
"Employment  Agreements")  that  commenced  on May  19,  1995.  Pursuant  to the
Employment Agreements,  if Messrs.  Phildius and/or Scott are terminated without
"Cause" (as such term is defined in the Employment Agreements) by the Company or
if Messrs.  Phildius and/or Scott  terminate  their  employment as a result of a

entitled  to receive  his annual  base salary  ($200,000  for Mr.  Phildius  and
$180,000  for  Mr.  Scott)  for a  period  of up to  18  months  following  such
termination.  In addition,  if there is a "Change of Control" of the Company (as
such  term is  defined  in the  Employment  Agreements)  and,  within  two years
following  such  "Change of  Control",  either of Messrs.  Phildius  or Scott is
terminated without cause by the Company or terminates his employment as a result
of a breach by the Company,  such executive will be entitled to certain payments
and benefits,  including the payment, in a lump sum, of an amount equal to up to
two  times  the sum of (i) the  executive's  annual  base  salary  and  (ii) the
executive's  most recent  annual bonus (if any).  In  addition,  pursuant to the
Employment  Agreements,  which have a three-year  term  (subject to  extension),
Messrs.  Phildius and Scott are each entitled to annual bonus  payments of up to

                                   ITEM NO. 2

APPROVAL OF THE ISSUANCE OF THE MAXIMUM NUMBER OF SHARES OF THE COMPANY'S COMMON
STOCK ISSUED OR ISSUABLE IN CONNECTION WITH THE PRIVATE  PLACEMENT  COMMENCED IN
FEBRUARY  2003,   INCLUDING  SHARES  ISSUABLE  UPON  CONVERSION  OF  OUTSTANDING
SUBORDINATED NOTES.

The Board of  Directors  has  unanimously  approved,  and is  hereby  soliciting
stockholder  approval of, the issuance and  reservation of the maximum number of
shares of common  stock  issued and  issuable  in  connection  with the  private
placement described below.

BACKGROUND

     In February  2003,  the Company  through a  placement  agent,  Brenner/HCFP
Securities,  LLC.  ("HCFP")  commenced  a  private  placement,  which was a best
efforts  offering  with a minimum of $850,000 and a maximum of  $1,850,000  (the
"Private  Placement").  During that month, the Company entered into Subscription
Agreements with accredited investors  (collectively,  the "Purchasers")  raising
gross proceeds of $955,000 and the Private Placement  terminated without further
subscriptions  on April 15, 2003.  The  Purchasers  acquired units (or fractions
thereof) at a price per unit of $50,000.  Each "Unit" consisted of (a) a $50,000
15% Senior Subordinated  Promissory Note  ("Subordinated  Note") and (b) 300,000
shares of common  stock.  The Company  sold and issued an  aggregate of $955,000
Subordinated  Notes and 5,730,000  shares of common stock. The net proceeds were
used to make scheduled  principal  repayments on  outstanding  debt, to pay debt
interest  when due, to pay accounts  payable and  otherwise  to provide  working
capital.

REASONS FOR THIS PROPOSAL

     In the  Private  Placement,  and to  comply  with  applicable  rules of The
American Stock Exchange  (AMEX),  the Company agreed to seek the approval of its
shareholders  for both (a) the issuance and  reservation of all shares of common
stock issued or issuable in  connection  with the Private  Placement and (b) the
increase in its authorized  shares of common stock from  100,000,000 to at least
125,000,000 and the Board of Directors has determined to increase the authorized
shares of common stock to 150,000,000  ("Shareholder  Approval").  (The proposed
increase of authorized shares is discussed in Item No.3 below.)

     The  Company's  common  stock  trades on AMEX.  According  to AMEX  Listing
Standard Section 713, the Company is required to obtain stockholder  approval of
the sale,  issuance or potential  issuance of the  Company's  common  stock,  or
securities  convertible into the Company's common stock, if the aggregate number
of  shares  to be issued  or could be  issued  in the  transaction  and  related
transactions  equals or exceeds 20% of the Company's then outstanding  shares of
common stock on the date of issuance (the "Share  Limit") and the purchase price
for such  securities  is less than the greater of the book value or market value
of the common stock on the date of issuance (the "Value Limit").

     As of the  commencement and initial closing of the Private  Placement,  the
aggregate  number of shares of common  stock that may be issuable in the Private
Placement,  including upon conversion of the  Subordinated  Notes,  exceeded the
Share Limit and the purchase price was less than the Value Limit.  Therefore, in
accordance  with AMEX  Listing  Standard  Section 713, the Company is asking its
stockholders  to approve the issuance and  reservation  of the maximum number of
shares of Common Stock issuable in the Private Placement.

KEY TERMS OF THE PRIVATE PLACEMENT AND SUBORDINATED NOTES

     Registration of Shares of Common Stock.  The Company has agreed to register
the shares of common  stock  issued or issuable in  connection  with the Private
Placement,  including shares issuable upon conversion of the Subordinated Notes.
As part of its compensation,  the Placement Agent received (a) 10% of the shares
of common  stock  issued and (b)  Warrants to purchase  10% of the common  stock
issuable on conversion of the Subordinated Notes,  exercisable at the conversion
price of the  Subordinated  Notes, and all of these shares are to be registered.
If the  Company  failed  to file its  Registration  Statement  on time or if the
Registration  Statement  did not  become  effective  by 90 days  after the final
closing of the Private  Placement,  the Company will be obligated  under certain
circumstances  to  issue  additional  shares  as  liquidated  damages  ("Penalty
Shares").  If Shareholder  Approval is not obtained,  with Penalty Shares, it is
possible that the Company may exceed the Share Limit and therefore be subject to
delisting.

     Optional Conversion of Subordinated Notes. Subject to Shareholder Approval,
the  Subordinated  Notes,  including  accrued  but  unpaid  interest,   will  be
convertible, at the option of the holders, into shares of common stock initially
at  $0.207  per  share.  The  conversion  price  will  be  subject  to  standard
adjustments and, in addition, if shares (or derivative securities) are issued at
a price (or with exercise or conversion  prices) less than the conversion price,
the conversion price will be  automatically  reduced to that lower price. If all
the  Subordinated  Notes were  converted and in view of  anticipated  additional
issuances  to date of shares  at  prices  less  than the  conversion  price,  an
estimated  10.6 million  shares would be issued for the principal  amount alone.
While the Subordinated Notes bear 15% per annum, 10% is payable quarterly and 5%
accrues until maturity.

     Subordination.  The  Subordinated  Notes are subordinate only to the senior
indebtedness in the amount of approximately $1.5 million outstanding at the time
of issuance, but senior to all other debt of the Company.

     Holders of  Subordinated  Notes Right to Demand  Prepayment if  Shareholder
Approval is Not Obtained.  If Shareholder Approval is not obtained,  the holders
of the  Subordinated  Notes  will have the right to  demand  pre-payment  of the
Subordinated  Notes.  There can be no assurance that the Company will be able to
repay upon such demand.

REQUIRED VOTE

     Approval of the issuance and reservation of the maximum number of shares of
common  stock  issued or  issuable  in  connection  with the  Private  Placement
requires the affirmative  vote of the holders of a majority of the Avitar Common
Stock and Series B and D  Preferred  Stock  present in person or by proxy at the
Avitar Annual  Meeting  (assuming a quorum exists) and entitled to vote thereon.
(The holders of the 6,303,000  shares of Common Stock  previously  issued in the
Private Placement,  if present in person or by proxy at the duly convened Annual
Meeting,  will be entitled to vote on all matters that  properly come before the
meeting, including this Item No. 2.)

BOARD RECOMMENDATION

The Board of Directors of Avitar  unanimously  recommends a vote FOR approval of
the issuance and  reservation of the maximum number of shares issued or issuable
in connection with the Private Placement.



                                   ITEM NO. 3

APPROVAL OF AMENDMENT OF CERTIFICATE OF  INCORPORATION  TO EFFECT AN INCREASE OF
AUTHORIZED SHARES OF COMMON STOCK FROM 100,000,000 TO 150,000,000

     The Board of Directors has unanimously  approved,  and is hereby soliciting
stockholder  approval of, an amendment to the Certificate of Incorporation  (the
"Amendment"), effecting an increase in the number of authorized shares of Common
Stock from 100,000,000 to 150,000,000.

     The Certificate of  Incorporation  now provides for 100,000,000  authorized
shares of Common  Stock,  par value $.01 per  share,  of which  72,108,143  were
issued and outstanding as of the Record Date; and 5,000,000  shares of Preferred
Stock,  par value $.01, of which 136,202 were issued and  outstanding  as of the
Record Date.  The Amendment  would  increase the number of authorized  shares of
Common Stock to 150,000,000.

REASONS FOR THE INCREASE

     In the  Private  Placement,  and to  comply  with  applicable  rules of The
American Stock Exchange  (AMEX),  the Company agreed to seek the approval of its
shareholders  for both (a) the issuance and  reservation of all shares of common
stock issued or issuable in  connection  with the Private  Placement and (b) the
increase in its authorized shares of common stock, as determined by the Board of
Directors, from 100,000,000 to 150,000,000 ("Shareholder Approval").

     Subject to Shareholder Approval and in view of anticipated adjustments, the
outstanding  Subordinated  Notes  will  be  convertible  in the  aggregate  into
approximately  10.6  million  shares of common  stock for the  principal  amount
alone. In addition, outstanding shares of Preferred Stock are now convertible in
the aggregate  into  approximately  2,446,000  shares of Common Stock.  Further,
holders of  outstanding  warrants  are  entitled  to purchase  approximately  14
million  shares of Common Stock at prices  ranging from $.01to  $3.83.  Finally,
there are  outstanding  employee  stock  options  (approximately  45% vested) to
purchase  approximately  10.5 million  shares of Common Stock at prices  ranging
primarily  from $.20 to $3.11 and an  additional  1.5  million  shares have been
reserved  for future  employee  stock  options and an  additional  approximately
950,000 shares of Common Stock are reserved for the 2001 Employee Stock Purchase
Plan.  Therefore,   on  a  fully  diluted  basis  and  in  view  of  anticipated
adjustments, the Company requires 112 million shares.

     The majority of the proposed  increase to 150,000,000  authorized shares of
Common  Stock will be shares  reserved  for the  conversion  of the  outstanding
Subordinated Notes, conversions of Preferred Stock, exercises of the outstanding
warrants and options,  future  financings to grow the business and completion of
acquisitions as described below.

     Proceeds  from any  exercises  of  outstanding  warrants  and  options  are
anticipated  to be used  primarily to provide the necessary  working  capital to
operate Avitar. For the balance of fiscal year 2003,  Avitar's cash requirements
are expected to include primarily the funding of operating  losses,  the payment
of outstanding  accounts payable and the repayment of certain notes payable and,
to the extent available, the funding of operating capital to grow Avitar's rapid
diagnostic testing and other lines of business.

     The Board of Directors  determined to increase the authorized  Common Stock
to 150,000,000  shares as required  pursuant to the  Subscription  Agreements to
ensure that  sufficient  shares of Common Stock were authorized and available to
cover the  outstanding  convertible  Subordinated  Notes  ($955,000 in principal
amount),  Preferred  Stock,  warrants and options and any  additional  shares of
Common or  Preferred  Stock and  warrants or options  which it may  determine to
issue or grant in the future.  Avitar is actively seeking additional funding and
additional shares are expected to be required in such financings.

     Further,  Avitar may explore  possible  acquisitions,  which  would  likely
involve  the  issuance  of some or all of the  additional  authorized  shares of
Common Stock as all or a portion of the purchase  prices of any  acquisitions of
companies,  businesses  and/or  assets it may effect in the  future.  In such an
event,  Avitar's  stockholders  would not need to be solicited  for any specific
acquisitions  if  they  approve  the  current  proposal  to  increase   Avitar's
authorized Common Stock. Accordingly, Avitar's stockholders' only opportunity to
specifically  vote on and approve any such  acquisitions  could be their vote on
the current proposal to increase  Avitar's  authorized  Common Stock.  Except as
disclosed  above,  Avitar does not believe that the  increase in its  authorized
Common Stock will have any  significant  effects on the  stockholders of Avitar,
nor does it believe that such increase will have any significant benefits to the
officers, directors or affiliates of Avitar.

     In order to effect  the  increase,  the  stockholders  are  being  asked to
approve the Amendment.  The Board of Directors  believes that the increase is in
the best  interests of Avitar and has  unanimously  approved the  increase.  The
Board of Directors may make any and all changes to the  Amendment  that it deems
necessary in order to file the  Amendment  with the Delaware  Secretary of State
and give effect to the increase.

NO DISSENTERS' RIGHTS

     Dissenting  stockholders  have no appraisal  rights  under  Delaware law or
under the Company's  Certificate of  Incorporation  or Bylaws in connection with
the increase.

REQUIRED VOTE

     Pursuant to the  Delaware  General  Corporation  Law,  the  approval of the
Amendment to Avitar's  Certificate of  Incorporation to provide for the increase
in number of authorized  shares of Common Stock requires the affirmative vote of
the holders of a majority of the  outstanding  shares of Avitar Common Stock and
Series B and D Preferred Stock.

BOARD RECOMMENDATION

     The Board of  Directors  of Avitar  unanimously  recommends  a vote FOR the
Amendment to the Company's  Certificate of  Incorporation to increase the number
of authorized shares of Common Stock from 100,000,000 to 150,000,000.


                                   ITEM NO. 4
                RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

     The Board of Directors of Avitar selected BDO Seidman,  LLP as auditors for
the fiscal year ending  September 30, 2003,  subject to stockholder  approval by
ratification.  BDO  Seidman,  LLP has been the  independent  auditors for Avitar
since  December  1992. A  representative  of BDO Seidman,  LLP is expected to be
present  at the Annual  Meeting,  at which  time he or she will be  afforded  an
opportunity to make a statement, and will be available to respond to questions.

     The Board of Directors of Avitar may, in its discretion, direct appointment
of new  independent  auditors  at any time  during the fiscal  year if the Board
believes  such  change  would  be in  the  best  interests  of  Avitar  and  its
stockholders. No such change is anticipated.

REQUIRED VOTE

     Approval of ratification of BDO Seidman,  LLP requires the affirmative vote
of the  holders of a  majority  of the  Avitar  Common  Stock and Series B and D
Preferred  Stock  present  in person or by proxy at the  Avitar  Annual  Meeting
(assuming a quorum exists) and entitled to vote thereon.

BOARD RECOMMENDATION

     The Board of  Directors  of Avitar  unanimously  recommends  a vote FOR the
ratification  of BDO  Seidman,  LLP as  auditors  for  the  fiscal  year  ending
September 30, 2003.


                              SHAREHOLDER PROPOSAL
                             ITEM NO. 5 ON PROXY CARD

The  shareholder  named below has told us that it intends to have the  following
proposal presented at the Annual Meeting.  Approval of the shareholder  proposal
requires the  affirmative  vote of a majority of eligible  shares present at the
Annual Meeting,  in person or by proxy,  and voting on the matter.  The Board of
Directors  has  concluded  that it cannot  support this proposal for the reasons
given.

Item 5 on Proxy Card

GIN99, LLC, 668 North Coast Highway, #225, Laguna Beach, CA 92651, owner of
6,462,515 shares of the Company's common stock, proposes the following:

"Proposal


     RESOLVED:  In an effort  to  address  the  serious  concerns  raised by the
Sarbanes-Oxley  Act of  2002  (the  "Act")  and  the  corporate  governance  and
compliance issues attendant thereto, the shareholders have determined that:

     The  positions  of Chief  Executive  Officer  and  Chairman of the Board be
segregated  so that  these  positions  are from  this time  forward  held by two
different individuals."


BOARD OF DIRECTORS' POSITION:

The Board of  Directors  believes  that the  establishment  of a Chairman of the
Board different from the Chief Executive  Officer will create another  personnel
requirement  without  sufficient  corresponding  benefit to the Company.  In the
Board's  opinion,  the  segregation  of the  positions  of  Chairman  and  Chief
Executive  Officer is impractical  and  excessively  expensive for Avitar or any
company similar in size and nature to Avitar.

The Board of Directors  believes that segregation of the Chairman and CEO is not
in the best interests of Avitar and its shareholders.

The Board of Directors recommends a vote AGAINST this proposal.




                                 OTHER BUSINESS

     The proxy  confers  discretionary  authority on the proxies with respect to
any other  business , which may come  before the  Annual  Meeting.  The Board of
Directors  of Avitar  knows of no other  matters to be  presented  at the Annual
Meeting. The persons named in the proxy will vote the shares for which they hold
proxies  according  to their best  judgment if any matters not  included in this
Proxy Statement properly come before the meeting.

                              STOCKHOLDER PROPOSALS

     Any stockholder  proposal to be included in the proxy statement and form of
proxy  relating  to the 2004  Annual  Meeting  of  Avitar  Stockholders  must be
received  by the close of  business  on  February 1, 2004 and must comply in all
other  respects with the rules and  regulations  of the  Securities and Exchange
