Stockholders  at which  they are  elected  or until  their  successors  are duly

BOARD MEETINGS AND COMMITTEES

     The Board held 4 meetings during the fiscal year ended September 30, 2000.

     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
2000, each Board member attended 100% 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,
usually  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  2000
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 in fiscal year 2000.





  AUDIT COMMITTEE REPORT

       In connection with the fiscal 2000 audit, the Audit Committee has:

     -    reviewed and discussed with management  Avitar's audited  consolidated
          financial  statements  to be  included  in our  annual  report on Form
          10-KSB for the year ended September 30, 2000,

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

     -    discussed  with  BDO  Seidman,  LLP  whether  various  other  services
          performed  for  Avitar  during  2000,  primarily  internal  audit  and
          consulting services, 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
          Independence  Standards  Board  Standard No. 1 and discussed  with BDO
          Seidman, LLP 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,  2000 for filing  with the  Securities  and  Exchange
Commission.

     The Board of Directors has approved a written  charter,  a copy of which is
attached to the Proxy  Statement as Annex A. 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  2000 Audit  Firm Fee  Summary.  During  fiscal  year  2000,  Avitar
retained its  principal  auditor,  BDO Seidman,  LLP to provide  services in the
following categories and amounts:





  Audit Fees..........................................................  $73,662
  Financial Information System Design and
         Implementation Fees..........................................  $22,154
  All Other Fees........................................................$30,510



          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 1 meeting in fiscal year 2000.










DIRECTOR COMPENSATION

     The Company presently pays its non-management directors $500 for each Board
and Committee meeting which they attend plus a travel fee of $250 if they travel
from  outside of the area to attend the  meeting.  Since Avitar does not pay its
non-management  directors an annual  retainer,  Avitar adopted a directors' plan
(the "Directors' Plan"), which was approved by the Stockholders on May 18, 1995.
Under the  Directors'  Plan,  each  non-management  director is granted  options
covering 5,000 shares of the Common Stock  initially upon election of the Board,
and each year in which he/she is selected to serve as a director. In March 1997,
each non-management director received a grant of 5,000 options for calendar year
1997 with an  exercise  price of $0.83 per share,  representing  the fair market
value of the Common  Stock on the date of such grant.  During  fiscal year 1998,
all options described above were canceled and replaced with options that have an
exercise price of $0.25 per share with no change in the expiration  dates.  Also
during fiscal year 1998, the non-management  directors were each granted options
to purchase  70,000 shares of the Common Stock at an exercise price of $0.25 per
share until February 4, 2008. These new options vested and became exercisable on
the basis of 50% on February 4, 1999 and 50% on February 4, 2000. In March 2000,
the non-management  directors were granted options covering 45,000 shares of the
Common  Stock at an  average  exercise  price of $1.57 per  share.  Such  grants
represent  options  owed to these  Directors  for 1998,  1999 and 2000 under the
Directors Plan. In March 2001, the non-management directors were granted options
to purchase  15,000 shares of the Common Stock at an exercise price of $1.08 per
share.  This grant represented the options due to these Directors for 2001 under
the Directors Plan.


     For   information   on   compensation   to   management   directors,    see
"Management-Executive Compensation" below.



SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

     The  following  table sets  forth the number of shares of the Common  Stock
beneficially  owned as of May 15, 2001 by (i) each person  believed by Avitar to
be the beneficial owner of more than 5% of the Common Stock; (ii) each director;
(iii) the Chief Executive Officer and its four most highly compensated executive
officers (other than the Chief Executive Officer) who earn over $100,000 a year;
and (iv) all directors and executive officers as a group.  Beneficial  ownership
by the stockholders has been determined in accordance with the rules promulgated
under Section  13(d) of the  Securities  Exchange Act of 1934,  as amended.  All
shares of the Common  Stock are owned both of record  and  beneficially,  unless
otherwise indicated.

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 written
representations from certain reporting persons that no Forms 5 were required for
those  persons,  Avitar  believes  that,  during  fiscal  year 2000,  all filing
requirements  applicable  to its  officers,  directors  and  greater  than  10 %
stockholders  were complied  with except the  following  failures to file timely
reports  required by Section 16(a):  One report (Form 4) covering 3 transactions
was filed late by James Groth.  One report (Form 4) covering 3 transactions  was
filed late by Charles McCarthy.  One report (Form 4) covering 4 transactions was
filed late by Neil Gordon.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     PK&S, a 3.4% beneficial owner of Avitar,  provided  consulting  services to
predecessors  of Avitar from September  1989 to May 1995. On May 28, 1992,  PK&S
entered into a written consulting  agreement pursuant to which PK&S provided the
services of each of Messrs.  Phildius and Scott for  approximately  20 hours per
week. Under the terms of the current  employment  agreements with Peter Phildius
and  Douglas  Scott  described  below,  Avitar pays their  salaries  and related
expenses  directly to PK&S. The aggregate of consulting fees,  salaries,  fringe
benefits and  reimbursement  of expenses paid to PK&S by Avitar for fiscal years
2000, 1999 and 1998 totaled $460,053, $387,310 and $335,137 respectively.

     In connection with its consulting  arrangement  with the Company,  PK&S was
granted  options to purchase an aggregate  of 1.6 million  shares of the Company
Common  Stock prior to the one for 54.9 stock  split  effected by the Company in
November 1991 (the "Stock Split"). In December 1991,  following the Stock Split,
the Company's Board of Directors  canceled these previously  granted options and
replaced them with five-year  options covering an aggregate of 120,000 shares of
the  Company  Common  Stock,  of  which  options  covering  60,000  shares  were
exercisable at $0.80 per share and options covering an additional  60,000 shares
were  exercisable  at $2.00 per  share.  Such  options  were  granted to PK&S as
compensation  for  services  rendered  to the  Company.  The number of shares of
Company Common Stock covered by such options was approximately  91,000 more than
those which PK&S would have received  pursuant to the Stock Split alone, and the
exercise  prices and other terms of such options were more  favorable than those
of the options that they  replaced.  On June 16, 1994,  the  Company's  Board of
Directors  canceled the options covering 60,000 shares with an exercise price of
$2.00 per share and replaced them with options covering a like number of shares,
at $0.59 per share, the fair market value of the Company Common Stock as of June
16, 1994.  The options  covering  60,000  shares of common stock at the exercise
price of $0.80 per share expired in December 1996.  The remaining  60,000 shares
of Company  Common Stock  covered by such options are subject to certain  demand
registration rights granted to PK&S. Pursuant to these registration rights, PK&S
has the right,  which  commenced on September  18, 1993, to cause the Company to
register the shares of the Company Common Stock underlying these options.

     In connection  with bridge loans totaling  $375,000 made by PK&S to Avitar,
PK&S, on September 30, 1995,  exchanged  its bridge note,  and accrued  interest
thereon, for 388,856 shares of Series A Convertible  Preferred Stock. Each share
of Series A Convertible  Preferred Stock entitled PK&S to convert it at any time
into three  shares of Common  Stock and receive  dividends in an amount equal to
110% of any  dividends  paid on the  Common  Stock  into  which  each  share  is
convertible. These shares of Series A Convertible Preferred Stock were converted
into 1,166,568 shares of Common Stock in February 1997.

     On May 19, 1995, the PK&S  Consulting  Agreement  ended and was replaced by
the   Employment    Agreements   with   Messrs.    Phildius   and   Scott   (See
"Management-Employment  Agreements" below). As requested by Messrs. Phildius and
Scott and approved by the Board of Directors,  the salary and benefits  provided
under the Employment Agreements are paid directly to PK&S.

     From  April-to-October  1997,  officers and  affiliates of the Company made
loans to Avitar  totaling  $428,723 with interest  payable at 10% per annum.  Of
these loans,  $368,723 was due on or before  September 30, 1997 with the balance
of $60,000 due on or before  January 31, 1998.  In November  1997,  loans in the
total  amount of $60,000  (plus the accrued  interest  thereon) due on or before
January 31,  1998 were  repaid.  In March 1998,  the  remaining  loans  totaling
$368,723 plus accrued interest  thereon of approximately  $31,000 were repaid by
Avitar with  1,818,020  shares of Common Stock and warrants to purchase  400,000
shares of Common Stock for $.28 per share until March 2003.

     During March 1999,  the  Chairman of the Board and the  President of Avitar
converted  notes payable  (including the accrued  interest  thereon) and accrued
salaries totaling approximately $200,000 into 24,570 shares of Avitar's Series B
Preferred Stock (which are convertible  into 245,700 shares of the Common Stock)
and warrants  exercisable for one year to purchase  400,000 shares of the Common
Stock at $1.22 per share. In March 2000,  warrants to purchase 268,000 shares of
the Common Stock were exercised.

     In October  1996,  Avitar  entered  into a consulting  agreement  with N.R.
Gordon & Company,  Inc. Neil Gordon, a member of the Board of Directors,  is the
President of N.R.  Gordon & 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 fees for certain  capital  raising  services.  During fiscal
year 1998,  Avitar amended its consulting  agreement with N.R. Gordon & Company,
Inc. to eliminate any fees associated with raising capital.  As compensation for
this amendment,  Avitar  canceled the 50,000  warrants  granted to N.R. Gordon &
Company in 1996 and replaced them with 100,000 warrants to purchase Common Stock
for $.25 per share until October 2001. In March 2001, the Company entered into a
new consulting  agreement with N.R. Gordon & Company,  Inc.  whereby N.R. Gordon
and Company,  Inc. provides financial  consulting services to Avitar. Under this
agreement,  N.R.  Gordon & Company,  Inc.  received  warrants to purchase 40,000
shares of Common  Stock for $.79 per share until  February  28, 2006 and is paid
$100.00 per hour for all services performed.

     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.

     EMPLOYMENT  AGREEMENTS.  In 1993,  Messrs.  Phildius and Scott entered into
Employment  Agreements (the  "Employment  Agreements")  with the Company.  These
Employment Agreements commenced May 19, 1995. Under these Employment Agreements,
Messrs. Phildius and Scott each receive an annual salary of $150,000 (subject to
cost of living  increases).  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  breach  by the  Company  of its
obligations  under such  Agreements,  he will be  entitled to receive his annual
base salary (currently $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 he
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 $150,000 if the  Company  achieves  certain  levels of
Pre-tax Income (as such term is defined in such Agreements).

REQUIRED VOTE

     Election of each of the five nominees for director requires, under Avitar's
Bylaws,  the affirmative  vote of the holders of a majority of the Avitar Common
Stock and Series B, C 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 Avitar Board of Directors unanimously recommends a vote FOR election of
all of the five nominees for director.

                                 PROPOSAL NO. 2


APPROVAL OF AMENDMENT OF CERTIFICATE OF  INCORPORATION  TO EFFECT AN INCREASE OF
AUTHORIZED SHARES OF COMMON STOCK FROM 75,000,000 TO 100,000,000

     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 75,000,000 to 100,000,000.

     The  Certificate of  Incorporation  now provides for 75,000,000  authorized
shares of Common  Stock,  par value $.01 per  share,  of which  34,665,840  were
issued and outstanding as of the Record Date; and 5,000,000  shares of Preferred
Stock,  par value $.01, of which 2,162,036 were issued and outstanding as of the
Record Date.  The Amendment  would  increase the number of authorized  shares of
Common Stock to 100,000,000.

REASONS FOR THE INCREASE

     The outstanding  shares of Preferred Stock are convertible in the aggregate
into  approximately  18 million shares of Common Stock. In addition,  holders of
outstanding warrants are entitled to purchase  approximately 9 million shares of
Common Stock at prices ranging from $0.225 to $6.05.  Further,  approximately  3
million  shares  will be  reserved  for  stocks  and  warrants  to be issued for
financial  consulting  services.  Finally,  there are outstanding employee stock
options  (approximately 25% vested) to purchase  approximately 10 million shares
of  Common  Stock at  prices  ranging  primarily  from  $0.20 to  $0.345  and an
additional 3 million shares have been reserved for future employee stock options
and an  additional  1 million  shares of Common Stock are to be reserved for the
proposed 2001 Employee Stock Purchase Plan.

     The majority of the proposed  increase to 100,000,000  authorized shares of
Common  Stock will be shares  reserved  for the  conversion  of the  outstanding
Preferred  Stock,  exercises of the  outstanding  warrants  and options,  future
financings  to grow the business and  completion  of  acquisitions  as described
below.

     Proceeds from the recently completed private placements of Common Stock and
Series D  Preferred  Stock ($4  million)  and  proceeds  from any  exercises  of
outstanding warrants and options are anticipated to be used primarily to provide
the necessary  working capital and capital  equipment  funding to operate Avitar
and expand its  business.  For the  balance of fiscal year 2001,  Avitar's  cash
requirements are expected to include  primarily the funding of operating capital
to grow  Avitar's  rapid  diagnostic  testing and other lines of  business,  the
funding of operating losses, the payment of outstanding accounts payable and the
repayment of certain notes payable.

     The Board of Directors  determined to increase the authorized  Common Stock
to  100,000,000  shares to ensure that  sufficient  shares of Common  Stock were
authorized and available to cover then outstanding  convertible 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 exploring 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, C 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 75,000,000 to 100,000,000.


                                 PROPOSAL NO. 3

APPROVAL OF THE BOARD OF DIRECTORS  PROPOSAL TO ESTABLISH AND IMPLEMENT THE 2001
EMPLOYEE STOCK PURCHASE PLAN.

     At the  meeting,  the  shareholders  will be  requested to approve the 2001
Employee  Stock  Purchase  Plan (the  "Purchase  Plan").  The  Board  recommends
approval  of the  Purchase  Plan in order  to allow  the  Company  to offer  its
employees the ability to invest in the  Company's  common stock at an attractive
price. A copy of the Purchase Plan may be obtained upon request to the Company's
Investor Relations Department at the address listed on the cover.

DESCRIPTION OF THE PLAN

     The  Purchase  Plan,  if  approved  by the  shareholders,  will  allow  all
employees  working more than 20 hours a week and more than five months a year to
authorize payroll deductions at any  non-fractional  percentage rate between and
including 1% and 10% of base pay  (including  overtime or bonuses) to be applied
toward the  purchase  of the  Company's  common  stock.  There will be 1 million
shares of common  stock  reserved for issuance  under the Purchase  Plan.  As of
April 30, 2001, there were  approximately 100 employees  eligible to participate
in the Purchase  Plan.  The Purchase Plan,  which is to be  administered  by the
Board,  will  terminate on June 30, 2007,  or earlier at the  discretion  of the
Board or in the event all shares reserved under the plan have been purchased.

     Separate six-month offerings commence on January 1 and July 1 of each year.
No  employee  may  purchase  more than 8,000  shares of stock  during any single
offering.

     An  employee  must  authorize  a payroll  deduction  before the start of an
offering in order to participate  in that offering.  On the last business day of
the  offering,  the  employee  will be deemed to have  exercised  the  option to
purchase as many shares as the employee's  payroll  deduction will allow, at the
option price. The option price is 85% of the lesser of (i) the fair market value
of the stock on the first business day of the offering,  or (ii) the fair market
value of the stock on the last business day of the  offering.  The closing price
of the Company's  common stock as reported on the American Stock Exchange on May
9, 2001 was $0.89.

     An employee may withdraw from an offering at any time. Upon withdrawal, the
amount in the employee's account will be refunded. An employee who has withdrawn
from an offering may not again  participate  in the Purchase Plan until the next
offering commences.

     No employee  shall be  permitted  to purchase any shares under the Purchase
Plan if such employee,  immediately after such purchase,  owns shares possessing
five percent or more of the total combined  voting power or value of all classes
of stock of the  Company.  The fair market  value of all shares  purchased by an
employee  under the  Purchase  Plan  during  any  calendar  year may not  exceed
$25,000.

     Because the  purchase of shares under the  Purchase  Plan is  discretionary
with all eligible  employees,  it would not be meaningful to include information
as to the amount of shares  which would have been  distributable  during  fiscal
2000 to all employees,  or to groups of employees, or to any particular employee
of the Company had the Purchase Plan been in effect during the year.

     The Board of  Directors  may at any time amend or  terminate  the  Purchase
Plan,  provided that no employee's  existing  rights under any offering  already
commenced  may be adversely  affected  thereby.  No amendment may be made to the
Purchase Plan without prior approval of the  shareholders of the Company if such
amendment  would increase the number of shares reserved  thereunder,  materially
modify the eligibility  requirements,  or materially  increase the benefits that
may accrue to participants.

FEDERAL INCOME TAX CONSEQUENCES RELATING TO THE PURCHASE PLAN

     The federal income tax  consequences  of an employee's  purchases under the
Purchase  Plan will  vary.  The  following  discussion  is only a summary of the
general  federal  income tax rules  applicable to the Purchase  Plan.  Employees
should  consult their own tax advisors since a taxpayer's  particular  situation
may be such that some variation of the rules described below will apply.

     The  Purchase  Plan  and  the  right  of  participants  to  make  purchases
thereunder  are intended to qualify under the  provisions of Section 421 and 423
of the Code. Under those provisions,  no income will be taxable to a participant
at the time of grant of the option or purchase of shares. However, a participant
may  become  liable  for tax upon  dispositions  of  shares  acquired  under the
Purchase  Plan  (or  if he or  she  dies  holding  such  shares),  and  the  tax
consequences  will depend on how long a participant has held the shares prior to
disposition.

     If the shares are  disposed of (a) at least two years after the date of the
beginning  of the  offering  period and (b) at least one year after the stock is
purchased in  accordance  with the Purchase  Plan (or if the employee dies while
holding the shares), the following tax consequences will apply.

     In this  event,  the lesser of (a) the excess of fair  market  value of the
shares at the time of such  disposition  over the  purchase  price of the shares
(the "option  price"),  or (b) the excess of the fair market value of the shares
at the time the option was granted  over the option  price  (which  option price
will be computed as of the offering date) will be treated as ordinary  income to
the participant.  Any further gain upon  disposition  generally will be taxed at
long-term capital gain rates. If the shares are sold and the sales price is less
than the option price,  there is no ordinary  income and the  participant  has a
long-term capital loss equal to the difference.  If an employee holds the shares
for this period,  no deduction in respect of the disposition of such shares will
be allowed to the Company.

     If the shares are sold or disposed of (including by way of gift) before the
expiration  of either  the two year or the one year  holding  periods  described
above, the following tax consequences will apply.

     In this event,  the amount by which the fair market  value of the shares on
the date the option is exercised (which is the last business day of the offering
period and which is hereafter referred to as the "termination date") exceeds the
option price will be treated as ordinary income to the participant.  This excess
will constitute ordinary income in the year of sale or other disposition even if
no gain is realized on the sale or a gratuitous  transfer of the shares is made.
The  balance of any gain will be treated as capital  gain and will  qualify  for
long-term  capital gain treatment if the shares have been held for more than one
year following the exercise of the option.  Even if the shares are sold for less
than  their  fair  market  value on the  termination  date,  the same  amount of
ordinary  income is attributed  to a  participant  and a capital loss is allowed
equal to the difference  between the sales price and the value of such shares on
such termination date. The Company,  in the event of an early disposition,  will
be allowed a deduction  for federal  income tax  purposes  equal to the ordinary
income realized by the disposing employee.


REQUIRED VOTE

     Approval of the Board of Directors' proposal to establish and implement the
Purchase Plan requires the affirmative  vote of the holders of a majority of the
Avitar  Common Stock and Series B, C and D Preferred  Stock present in person or

vote thereon.


BOARD RECOMMENDATION

     The Board of Directors of Avitar unanimously recommends a vote FOR approval
of the 2001 Employee Stock Purchase Plan.



                                 PROPOSAL NO. 4
                RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

     The Board of Directors of Avitar may, in its discretion, direct appointment

believes  such  change  would  be in  the  best  interests  of  Avitar  and  its
stockholders. No such change is anticipated.

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

                                  APPENDIX A

                                  AVITAR, INC.
                             AUDIT COMMITTEE CHARTER

Organization

There  shall be a  committee  of the  board  of  directors  known  as the  audit
committee.  The audit committee shall be comprised of directors, the majority of
whom  are  independent  (as  defined  in the  American  Stock  Exchange  Listing
Standards) of the management of the corporation and are free of any relationship
that,  in the  opinion of the board of  directors,  would  interfere  with their
exercise of independent judgment as a committee member.

Statement of Policy

The audit  committee  shall provide  assistance  to the  corporate  directors in
fulfilling their  responsibilities to the shareholders,  potential  shareholders
and investment community relating to corporate  accounting,  reporting practices
of the  corporation,  and the quality and integrity of the financial  reports of
the corporation. In so doing, it is the responsibility of the audit committee to
maintain  free and open  means  of  communication  between  the  directors,  the
independent auditors and the financial management of the corporation.

Responsibilities

The audit committee believes its policies and procedures should remain flexible,
in order to best react to changing  conditions  and ensure to the  directors and
shareholders that the accounting and reporting  practices of the corporation are
in accordance with all requirements and are of the highest quality.

In carrying out its responsibilities, the audit committee will:

o    Review and make a recommendation to the directors regarding the independent
     auditors  to  be  selected  to  audit  the  financial   statements  of  the
     corporation and its subsidiaries.

o    Meet  with  the  independent  auditors  and  financial  management  of  the
     corporation  to review the scope of the proposed audit for the current year
     and the audit  procedures  to be utilized,  and at the  conclusion  thereof
     review  such  audit,  including  any  comment  or  recommendations  of  the
     independent auditors.

o    Review  with  the  independent  auditors  and  the  corporation's  internal
     financial and accounting  personnel the adequacy and  effectiveness  of the
     accounting and financial controls procedures of the corporation, and elicit
     any recommendations for the improvement of such internal control procedures
     or particular  areas where new or more detailed  controls or procedures are
     desirable.  Particular  emphasis  should be given to the  adequacy  of such
     internal  controls to expose any payments,  transactions or procedures that
     might be deemed illegal or otherwise improper.

o    Review the audited financial statements to be included in the annual report
     to  shareholders  and the annual report filed with  Securities and Exchange
     Commission  ("SEC")  on Form  10KSB  with  management  and the  independent
     auditors to determine that the independent  auditors are satisfied with the
     disclosure  and content of the financial  statements to be presented to the
     shareholders and filed with the SEC. Make a recommendation  to the board of
     directors  regarding the inclusion of the audited  financial  statements in
     such  annual  reports.  Any  changes  in  accounting  principles  should be
     reviewed.

o    Review the financial  information  included in the corporations'  Quarterly
     Reports on Form 10QSB prior to the  corporation  filing such  reports  with
     Securities and Exchange Commission.

o    Provide  sufficient  opportunity for the independent  auditors to meet with
     members of the audit committee without members of management present. Among
     the items to be discussed in these meetings are the  independent  auditors'
     evaluation of the corporation's financial and accounting personnel, and the
     cooperation that the independent auditors received during the course of the
     audit.

o    Review the matters  discussed at each  committee  meeting with the board of
     directors.

o    Investigate  any matter  brought to its  attention  within the scope of its
     duties,  with the power to retain  outside  counsel for this purpose if, in
     its judgment, that is appropriate.
