Independent Auditors' Report



To the Board of Directors of
United States Drug Testing Laboratories, Inc.
Des Plaines, IL


We have audited the  accompanying  balance  sheets of United States Drug Testing
Laboratories,  Inc. as of December 31, 1998 and 1997 and the related  statements
of  operations  and  deficit  and cash  flows for the years  then  ended.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the  financial  position of United  States Drug Testing
Laboratories,  Inc.  as of December  31,  1998 and 1997,  and the results of its
operations  and its cash  flows  for the years  then  ended in  conformity  with
generally accepted accounting principles.

     specialized   laboratory  testing  Operations   including  substance  abuse

2.   Summary of Accounting Policies

     Property  and  Equipment

          Property and  equipment are stated at cost.  Depreciation  is computed
     using the  Equipment  straight-line  method  over the  following  estimated
     useful lives:

                                                                           Years

          License  fees are being  amortized  on a  straight-line  basis  over 5
     years.

     Income Taxes

          The absence of a  provision  for  federal  income  taxes is due to the
     election by the  corporation,  and consent by its  shareholders  to include
     their  respective  shares of  taxable  income of the  corporation  in their
     individual  tax returns.  As a result,  no federal income tax is imposed on
     the corporation.

     Cash Equivalents

          The Company considers all highly liquid investments  purchased with an
     original maturity of three months or less to be cash equivalents.

     Estimates and Assumptions.

          The  preparation of financial  statements in conformity with generally
     accepted   accounting   principles  requires  Company  management  to  make
     estimates and  assumptions  that affect the reported  amounts of assets and
     liabilities and disclosure of contingent assets and liabilities at the date
     of the  financial  statements  and the  reported  amounts  of  revenue  and
     expenses during the reported period. Actual results could differ from those
     estimates and assumptions.

     Research and Development

          Research and development costs are expensed as incurred.

8.   Commitments and
     Contingencies
     (Continued)

     Year 2000 Issues (Unaudited)

          Like other companies,  United States Drug Testing  Laboratories,  Inc.
     could be  adversely  affected  if the  computer  systems the  Company,  its
     suppliers  or  customers   use  do  not  properly   process  and  calculate
     date-related  information  and  data  during  the  period  surrounding  and
     including January 1, 2000. This is commonly known as the "Year 2000" issue.
     Additionally, this issue could impact non-computer systems and devices such
     as  production  equipment,  elevators,  etc.  At this time,  because of the
     complexities  involved in the issue,  management cannot provide  assurances
     that  the  Year  2000  issue  will  not  have an  impact  on the  Company's
     operations.

     shares of Avitar's common stock.

Pro Forma Condensed Combined Financial Statements


Introduction:

On July 9, 1999 the  Registrant  acquired all the  outstanding  capital stock of
United  States  Drug  Testing  Laboratories,  Inc.  ("USDTL")  in  exchange  for
approximately 2 million restricted shares of common stock of the Registrant. The
amount of consideration was determined by arm's length  negotiation  between the
Registrant  and the  majority  stockholders  of USDTL,  taking into  account the
revenues and  prospects  for USDTL.  The  Registrant  acquired  the  outstanding
capital stock of USDTL from its shareholders  Veronica Lewis,  Douglas Lewis and
Christine  Moore.  In connection  with the  Registrant's  acquisition  of USDTL,
Douglas Lewis and Christine Moore have entered into Employment Agreements.

The  unaudited  pro forma  condensed  combined  balance  sheet of  Avitar,  Inc.
("Avitar") as of June 30, 1999 assumes the acquisition of USDTL occurred on that
date.

The unaudited pro forma condensed combined statements of operations for the year
ended  September  30, 1998 and the nine months  ended June 30, 1999  present the
results of operations as if the USDTL  acquisition  had been  consummated  as of
October 1, 1997. The operating results for USDTL for the year ended December 31,
1998 were used to prepare the unaudited pro forma condensed  combined  statement
of operations for Avitar's  fiscal year ended  September 30, 1998.  Accordingly,
the unaudited  operating  results for USDTL for the three months ended  December
31, 1998, which included revenue of $389,186 and net income of $71,126 have been
included in both periods presented.

The  unaudited  pro forma  condensed  combined  financial  statements  have been
prepared by Avitar and all  calculations  have been made based upon  assumptions
deemed  appropriate.  The  unaudited  pro  forma  condensed  combined  financial
statements were prepared  utilizing the accounting  policies of Avitar.  The pro
forma  adjustments  reflect the acquisition being recorded as a purchase and the
preliminary  allocation of the purchase price and  accordingly may be subject to
certain  adjustments  as the Company  finalizes  the  allocation of the purchase
price in accordance with generally accepted accounting principles.  The purchase
price has been  allocated  based upon the estimated fair value of the assets and
liabilities acquired.

The unaudited pro forma financial  information does not purport to be indicative
of the results of operations or the financial position which would have actually
been obtained if the acquisition had been consummated on the dates indicated. In
addition,  the unaudited pro forma financial  information does not purport to be
indicative of results of operations or financial  position which may be achieved
in the future.

The unaudited pro forma financial information should be read in conjunction with
Avitar's  historical   consolidated   financial  statements  and  notes  thereto
contained in the 1998 Annual Report on form 10-KSB and the  Quarterly  Report on
Form 10-QSB for the quarter ended June 30, 1999, and the financial statements of
USDTL presented herein.
