                                  THE COMPANY

    ATC  is  a  national  environmental  consulting  and  engineering  firm that
provides specialized technical and project management products and services to a
large,  diverse  client  base  of  businesses  and  federal,  state  and   local
governments.   Since  entering  the  environmental  consulting  and  engineering
business in  1982,  ATC has  completed  several acquisitions  and  expanded  its
internal  operations, enabling  it to  increase its  market penetration  and the
variety of products  and services it  offers. The Company  currently operates  a
network  of  over  30  branch  offices  located  throughout  the  United States,
supported by in-house testing laboratories.

    The public's concern regarding exposure to contaminants stimulated the  push
for  environmental  regulations  in the  1970s  and 1980s.  Today,  the public's
continuing demand for responsible action  regarding human health and safety  and
the  potential adverse impact of environmental  liabilities drive the market for
environmental  consulting   and  engineering   services.  Independent   industry
estimates of the consulting and engineering services sector of the environmental
market  for 1994 ranged from $13 to $15 billion, with annual growth projected at
5% to 8% through the next three to four years.

    ATC has  focused on  five areas  of specialization:  (i) industrial  hygiene
consulting,  including  asbestos  management, classical  industrial  hygiene and
indoor air  quality;  (ii)  environmental  management,  including  environmental
audits,  site assessments,  remedial action  planning and  design, and  soil and
groundwater remediation management; (iii) lead-based paint risk management; (iv)
health and safety  consulting, including health  and safety training,  hazardous
materials  site  safety  planning  and  industrial  safety  consulting;  and (v)
management information systems for  comprehensive environmental risk  assessment
and  management. These  areas of  specialization contributed  approximately 65%,
19%, 10%, 5% and 1%, respectively, of the Company's revenues in fiscal 1995.

    The Company believes  that certain sectors  of the environmental  consulting
and  engineering market will experience significant growth over the next several
years with  demand for  products and  services growing  even in  the absence  of
increased  governmental regulations. Independent industry sources project annual
growth rates  of  10%,  13%,  15%  and  20%  for  lead-based  paint  management,
occupational   safety  and  industrial  hygiene  services,  indoor  air  quality
consulting and environmental software, respectively.

    The Company has experienced substantial increases in revenues and net income
over the past three fiscal  years. ATC's revenues were $16,539,254,  $26,664,385
and  $36,271,557,  respectively,  in  its  1993,  1994  and  1995  fiscal years,
representing a  compounded  annual  growth  rate of  48.1%  over  such  periods.
Furthermore,   ATC's  net  income  was   $353,144,  $1,867,048  and  $3,256,520,
respectively, in such fiscal years, representing a compounded annual growth rate
of 203.7% over  such periods. For  the Company's first  fiscal quarter of  1996,
revenues  increased 32.4%  to $10,814,953 over  the comparable  period of fiscal
1995, while net income increased 29.8%, to $895,128.

    ATC attributes these positive operating  results to its integrated  strategy
which  includes: (i) an  aggressive, but disciplined,  acquisition program; (ii)
the enhancement of  operations through  the integration  of acquired  businesses
with  the Company's existing operations; (iii)  a focus on certain higher growth
sectors of the  environmental consulting  and engineering  services market,  and
certain  higher margin services such as policy development and decision support;
(iv)  an  emphasis  on  basic  business  management  issues,  such  as  employee
utilization,  credit  and  collections management,  and  regional  profit center
accountability; and

                                       3

(v) the development of  a national presence  in a market  typified by local  and
regional  firms. Upon  the completion of  this offering, the  Company intends to
employ this strategy as it seeks to  further penetrate the markets for its  core
services  and to  expand its  range of  products and  services through strategic
acquisitions and internal growth.

    The Company's principal executive office is located at 104 East 25th Street,

                                  RISK FACTORS

    In  evaluating  an  investment in  the  Common Stock  being  offered hereby,
investors should  consider carefully,  among other  things, the  following  risk
factors,  as well as the other information  contained in this Prospectus and the
documents incorporated herein by reference.

GROWTH AND ACQUISITION RISKS

    One of the Company's primary strategies is to increase its revenues and  the
markets  it  serves through  the acquisition  of  other companies.  Although the
Company has  successfully  completed  several  acquisitions,  there  can  be  no
assurance  that  the Company  will be  able to  identify, acquire  or profitably
manage additional companies or successfully integrate such additional  companies
into  ATC's operations without  substantial costs, delays  or other problems. In
addition, there  can  be  no  assurance that  any  companies  acquired  will  be
profitable  at  the  time  of  their  acquisition  or  will  achieve  sales  and
profitability that justify  the investment therein.  Acquisitions may involve  a
number  of special  risks, including adverse  effects on  the Company's reported
operating results, diversion of management's attention, dependence on  retention
and  hiring of  key personnel, risks  associated with  unanticipated problems or
legal liabilities and amortization of acquired intangible assets, some or all of
which could  have a  material adverse  effect on  the Company's  operations  and
financial  performance.  The  expansion  of  the  Company's  operations, whether
through acquisitions or internal  growth, may place  substantial burdens on  the
Company's  management resources  and financial  controls. There  is no assurance
that the increasing burdens on the Company's management resources and  financial
controls  will not have an adverse effect  on the Company's operations. See "Use
of Proceeds" and "Business -- Strategy."

POTENTIAL LIABILITY AND INSURANCE

    The Company is engaged in a wide range of advisory services, from lead-based
paint risk  management and  industrial  hygiene to  health and  safety  training
programs.  Due to  the nature  of the  Company's services,  ATC is  exposed to a
significant risk of  professional liability for  environmental damage,  property
damage,  personal injury  and economic loss  which may  substantially exceed the
fees derived  from  such  services.  ATC currently  maintains  a  "claims  made"
professional   liability  insurance  policy,  including  contractor's  pollution
liability coverage, for claims  with a limit of  $2,000,000 and a deductible  of
$150,000, although increased limits have been obtained on a specific endorsement
basis to meet the needs of particular clients or contracts. The Company's policy
covers  both errors and  omissions. A "claims made"  policy only insures against
claims filed during the period  in which the policy  is in effect. Although  the
Company  believes that  its current level  of insurance coverage  is adequate to
protect it from the type and level of liability exposure that it can  reasonably
expect  to encounter during its ordinary  course of business, the coverage would
most likely be inadequate if a catastrophic event occurred for which the Company
was found to be  liable. The relatively  low dollar amount  of the policy  limit
currently maintained, the possible future unavailability or modification of this
insurance  or any significant increase in  insurance rates could have a material
adverse effect on ATC's  operations. Further, because  clients may require  that
ATC  maintain liability  insurance, the  possible future  unavailability of such
insurance could adversely affect  ATC's ability to  compete effectively. In  the
event  the Company expands  its services into  new markets, no  assurance can be
given that  the Company  will be  able  to obtain  insurance coverage  for  such
activities  or,  if  insurance  is  obtained,  that  the  dollar  amount  of any
liabilities incurred in connection  with the performance  of such services  will
not exceed policy limits. See "Business -- Insurance."

CHANGING REGULATORY ENVIRONMENT

    The growth of the environmental consulting and engineering services industry
has  been largely attributed to the increase in environmental regulation and the
response of governmental and commercial  entities and financial institutions  to
public  concern  with environmentally  contaminated  facilities. The  demand for
environmental consulting and engineering services has been, in part, the  result
of  facility owners  or operators attempting  to comply with  or avoid liability
under environmental regulations at the  federal, state or local levels.  Because
of  the burden imposed with respect  to complying with such regulations, various
groups have sought to relax or repeal certain forms of environmental regulation.
There can be no assurance that such

                                       6
<PAGE>
regulation will not be curtailed in the future. While the Company believes  that
the  demand  for  its  services  is  also  attributable  to  factors  other than
regulatory compliance, there can be  no assurance that changes in  environmental
laws  and regulations would not have a  material adverse effect on the Company's
business. See "Business -- The Environmental Consulting and Engineering Services
Industry" and "-- Environmental Regulation."

POTENTIAL ENVIRONMENTAL LIABILITY

    The Company's operations include advising  clients on the handling,  storage
and  disposal of hazardous  material, toxic wastes and  other pollutants and the
remediation of contamination. These services may expose the Company's  employees
and  others to  dangerous elements  and may  involve a  significant risk  to the
Company for liability for environmental damage, personal injury, property damage
and fines  and costs  imposed by  regulatory agencies.  Claims may  be  asserted
against  the Company  under federal and  state statutes  and regulations, common
law, contractual  indemnification  agreements  or otherwise.  There  can  be  no
assurance  that the Company will not be subject to claims which could materially
and  adversely  affect  the  operations   of  the  Company.  See  "Business   --
Environmental Regulation."

COMPETITION

    The environmental consulting and engineering services industry is fragmented
and  subject to intense  competition. In addition to  several thousand local and
regional consulting  firms, ATC  competes  with several  national  environmental
consulting  and  engineering  firms such  as  Law Engineering,  Inc.,  The Earth
Technology Corporation (USA), Professional Service Industries, Inc. and Dames  &
Moore,  Inc.  Many of  ATC's  present and  future  competitors may  have greater
financial, technical and personnel resources than ATC. Historically, competition
in the environmental consulting and engineering services industry has been based
primarily on  the quality,  timeliness  and costs  of services.  Competition  is
likely  to increase  as the  industry continues  to mature  and consolidate. See
"Business -- Competition."

FLUCTUATIONS IN OPERATING RESULTS

    The Company's operating  results may  vary from period  to period  due to  a
variety  of factors, including the size and timing of the Company's projects and
the impact of acquisitions.

                                USE OF PROCEEDS

   
    The net proceeds to  the Company from  the sale of  the 1,700,000 shares  of
Common  Stock being  offered by  the Company  are estimated  to be approximately
$22,945,000  after  deducting  underwriting  discounts  and  estimated  offering
expenses  payable  by the  Company.  The Company  will  not receive  any  of the
proceeds from the sale of the shares offered by the Selling Stockholders.
    

   
    The Company plans to utilize a portion of the net proceeds of this  offering
to  repay the debt outstanding under its credit facilities. At October 10, 1995,
$5,500,000 was outstanding under these credit facilities. It is anticipated that
a substantial portion  of the remaining  net proceeds of  this offering will  be
utilized  to expand the  Company's operations through  strategic acquisitions of
companies with  complementary services,  products or  technologies, as  well  as
through  internal expansion. In addition, the net proceeds of this offering will
be available for general working capital purposes.
    

    The Company is actively exploring acquisition opportunities, has  identified
a  number of companies which it might wish to acquire and has engaged in certain
preliminary due diligence activities. These activities have not resulted in  any
contract, understanding or arrangement for an acquisition as of the date of this
Prospectus.  Because a significant portion of the net proceeds will be available
for acquisitions, internal expansion and  general working capital purposes,  the
Company's  Board of  Directors will  have broad  discretion with  respect to the
application of  such  proceeds.  The  Company may  not  be  able  to  consummate
acquisitions   or  identify  and   obtain  projects  that   meet  the  Company's
requirements.

    Pending the application of such proceeds, the Company intends to invest  the
net  proceeds of this offering in bank deposits and short-term, investment grade
securities, including government obligations and money market instruments.

                              RECENT DEVELOPMENTS

MERGER OF AURORA INTO ATC

    Effective June  29,  1995, ATC  and  Aurora were  merged,  with ATC  as  the
surviving  corporation. Prior to the Aurora Merger, Aurora was a holding company
which owned  approximately  57%  of  ATC's  outstanding  Common  Stock  and  had
substantially  no other assets. In connection  with the merger, each outstanding
share of Aurora common stock was exchanged for .545 shares of Common Stock.  ATC
issued  3,341,452 shares  of Common  Stock in  exchange for  6,131,104 shares of
Aurora's common stock,  and issued  options and warrants  entitling the  holders
thereof  to  purchase up  to 604,950  shares  of Common  Stock upon  exercise in
replacement of previously outstanding options and warrants to purchase  Aurora's
common  stock. As a result of the Aurora Merger, ATC anticipates that it will be
able to  utilize  Aurora's  net operating  loss  carryforward  of  approximately
$970,000 at May 31, 1995. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."

ACQUISITION OF ASSETS OF CON-TEST

   
    Effective  October 1, 1994, ATC purchased certain assets and assumed certain
liabilities of  Con-Test,  a Massachusetts-based  environmental  consulting  and
engineering  company with branch offices in Massachusetts, Connecticut, Vermont,
Rhode Island, New  York and Pennsylvania.  Con-Test's primary services  included
industrial   hygiene,  environmental  and  industrial  health  and  safety,  and
lead-based paint management. It also maintained an analytical laboratory and had
developed a line of environmental facilities management software used by several
industrial firms and  federal government agencies.  The total consideration  for
this acquisition was approximately $7,760,000, consisting of $2,100,000 in cash,
restricted  shares of Common Stock valued  at $493,000, $535,000 in a three-year
promissory note, $4,500,000 of assumed liabilities and $132,000 for  acquisition
costs.   Certain  of  this  consideration   is  contingent  upon  collection  of
outstanding receivables acquired by ATC.  Immediately upon acquiring the  assets
of  Con-Test, the Company instituted several cost-saving measures, including the
elimination  of  certain  employees   and  facilities,  to  improve   Con-Test's
operations  and integrate it  with the existing operations  of the Company. (See
Pro Forma Unaudited Combined Financial Data and notes thereto included elsewhere
in this Prospectus.) On September 28, 1995, the Company served the seller with a
notice of set-off pursuant to the purchase agreement. Under this set-off, ATC is
entitled to recover shares of its  Common Stock orginally issued to the  seller,
valued  at the closing price of the stock at the date of the claim, equal to the
net uncollected  receivables  acquired  in the  purchase.  The  net  uncollected
receivables  were approximately $460,000 and  accordingly the Company expects to
recover approximately 32,000 shares of its Common Stock previously issued in the
acquisition. The effect  of this transaction  on the financial  position of  ATC
will  be to reduce the recorded net accounts receivable, reduce Common Stock and
additional paid in capital  and to increase goodwill.  This transaction will  be
recorded in the Company's third quarter.
    

OTHER RECENT ACQUISITIONS

    On January 4, 1995, ATC agreed to assume the service performance obligations
under  certain contracts of Microbial  Environmental Services, Inc. ("MES"). MES
was engaged  in the  business of  remediation of  contaminated soils  and  water
utilizing  enhanced  naturally  occurring  biological  processes.  The  services
provided by MES also included  assessment of contaminated properties, design  of
bio-remediation  systems, management of  bio-remediation projects and monitoring
of compliance with clean up standards.

    On January  13,  1995,  ATC  acquired certain  assets  and  assumed  certain
specified  liabilities of R.E.  Blattert and Associates  ("R.E. Blattert"). R.E.
Blattert's main area of expertise was in groundwater resource management.

EXERCISE OF CLASS B WARRANTS

    Between August 1, 1994  and September 30, 1994,  the Company received  gross
proceeds  of $2,278,424 from the  exercise of 284,803 of  the 285,817 issued and
outstanding Class B Common Stock  Purchase Warrants ("Class B Warrants"),  which
were  exercised at  an exercise  price of $8.00  per share.  Upon exercise, each
Class B  Warrant holder  received one  share of  Common Stock  and one  Class  C
Warrant.  The Class B Warrants  that were not exercised  expired as of September
30, 1994. The Class B Warrants were issued by the Company in 1990 in  connection
with  an  exchange  offer  pursuant  to  which  holders  of  the  Company's then
outstanding Common Stock Purchase Warrants received Class B Warrants in addition
to other consideration. See "Description of Capital Stock."

                            SELECTED FINANCIAL DATA
                     (IN THOUSANDS, EXCEPT PER SHARE DATA)

    The  following table sets forth, for the periods and at the dates indicated,
selected historical and pro  forma consolidated financial  data of the  Company.
The unaudited consolidated financial statements of the Company as of and for the
six  months ended August 31, 1994 and  1995 reflect all adjustments necessary in
the opinion of  the Company's  management (consisting only  of normal  recurring
adjustments),  for  a fair  presentation of  such  financial data.  The selected
consolidated historical financial  data has  been derived from  the audited  and
unaudited  historical consolidated financial  statements of the  Company, and in
the case of  fiscal years ended  February 28, 1993,  1994 and 1995  and the  six
months  ended August 31, 1994  and 1995 should be  read in conjunction with such
financial  statements  and  the  notes   thereto  included  elsewhere  in   this
Prospectus.

    The  pro forma unaudited  combined financial data has  been derived from the
audited and unaudited financial statements of the Company, Aurora and  Con-Test,
and  should  be  read  in  conjunction with  the  pro  forma  unaudited combined
financial data and notes thereto included elsewhere in this Prospectus. The  pro
forma  results of operations for the fiscal year ended February 28, 1995 and the
six months ended August 31, 1995  are not necessarily indicative of the  results
of  operations  that would  have been  achieved  had the  transactions reflected
therein been consummated prior to the  periods in which they were completed,  or
that might be attained in the future.

  SIX MONTHS ENDED AUGUST 31, 1995 COMPARED WITH SIX MONTHS ENDED AUGUST 31,
1994
    

   
    Revenues  in  the  six  months  ended August  31,  1995  increased  33.0% to
$22,464,431 compared with $16,889,112 in the  six months ended August 31,  1994.
This  increase was primarily attributable to the positive effect of acquisitions
completed during the  second half of  fiscal 1995. During  the six months  ended
August 31, 1995, increased revenues from certain existing operations were offset
by  lower revenues  from a  significant customer  due to  delays in  funding for
certain projects  and the  completion of  certain work  for another  significant
customer.
    

   
    Revenues  in the six months ended August  31, 1995 from ATC's branch offices
having comparable operations in the six  months ended August 31, 1994  increased
1.2%  to $17,092,786, compared  with $16,889,112 in the  six months ended August
31, 1994. If revenues from certain large projects for two significant  customers
discussed  below are  eliminated in  each period,  ATC's revenues  from existing
branch offices  having  comparable  operations would  have  increased  17.7%  to
$14,919,939  in the six months ended  August 31, 1995, compared with $12,673,323
in   the   six   months   ended   August   31,   1994.   In   the   six   months
    

                                       15

ended  August  31, 1995,  ATC continued  to penetrate  its existing  markets and
benefitted from the  acquisitions of certain  assets of Con-Test,  MES and  R.E.
Blattert.  Revenues attributable to operations resulting from these acquisitions
totaled $5,371,645, or 23.9%  of revenues, for the  six months ended August  31,
1995.
    

   
    Revenues  in the six months  ended August 31, 1995  earned directly from the
New York  City  School  Construction Authority  ("NYCSCA")  decreased  21.9%  to
$1,416,786, compared with $1,814,420 in the six months ended August 31, 1994. As
a  percentage of revenues, revenues from the NYCSCA decreased to 6.3% in the six
months ended August 31, 1995, compared with 10.7% in the six months ended August
31, 1994. During the first quarter of fiscal 1996, delays in the approval of the
NYCSCA's program  budget and  funding  requests for  the  New York  City  school
construction  and maintenance program  resulted in diminished  service levels in
asbestos management  consulting and  testing services  and, consequently,  lower
revenues  to ATC under  this program. The  NYCSCA's construction and maintenance
program is ongoing  and is  expected to  continue over  a period  of years.  ATC
believes it has established a strong relationship with the NYCSCA and expects to
continue to provide asbestos and other industrial hygiene services to the NYCSCA
over  the next several  years; however, no  assurance can be  made regarding the
amount of revenues, if any, that ATC will receive from the NYCSCA in the  future
once  current projects are completed. ATC's revenues under programs such as this
one are not  predictable and will  be dependent  upon many factors  such as  the
scope  of  work necessary  at particular  sites,  budgeting constraints  and the
timing of projects.
    

   
    Revenues in the  six months ended  August 31,  1995 from the  Army Corps  of
Engineers (the "Corps") decreased 68.5% to $756,061, compared with $2,401,369 in
the six months ended August 31, 1994. As a percentage of revenues, revenues from
the  Corps decreased to 3.4%  in the six months  ended August 31, 1995, compared
with 14.2% in the six months ended August 31, 1994. The Company's revenues  from
the  Corps relates to certain asbestos  management services and decreased due to
the completion of the larger phases of  the project during the six months  ended
August  31, 1994. Revenues  from the Corps  are expected to  continue at current
levels for the remainder of fiscal 1996 and work on this project is expected  to
continue  through  1999 as  part  of the  federal  Base Realignment  and Closure
project. However, no assurance can be made as to the amount of revenues, if any,
that ATC will receive  from the Corps  in the future  once current projects  are
completed.
    

   
    Gross  profit in  the six  months ended August  31, 1995  increased 29.2% to
$10,798,958, compared with $8,355,345 in the  six months ended August 31,  1994.
Gross  margin  decreased to  48.1%  in the  six  months ended  August  31, 1995,
compared with 49.5% in the six months ended August 31, 1994. ATC's gross  margin
decreased  due to  higher field  labor cost  and higher  subcontract and project
costs. The gross margin for the six months ended August 31, 1994 was higher  due
to the profitability level of several high margin projects.
    

   
    Operating  expenses in the six months  ended August 31, 1995 increased 29.9%
to $7,186,019 compared with $5,531,807 in the six months ended August 31,  1994.
Operating  expenses decreased as  a percentage of  revenues to 32.0%  in the six
months ended August 31, 1995, compared with 32.8% in the six months ended August
31, 1994. The decrease in operating expenses  as a percentage of revenue is  the
result  of ATC's ability to service greater revenue levels without corresponding
increases in fixed and administrative  costs. Employee costs increased 26.7%  to
$3,630,992,  or  16.2% of  revenues, in  the  six months  ended August  31, 1995
compared with $2,866,910, or 17.0% of  revenues, in the six months ended  August
31,  1994. These  increases in  employee costs  were due  to employees  hired in
connection with the expansion of ATC's operations. Other increases in  operating
expenses  resulted from  higher facility costs,  equipment and  supply costs and
administrative expenses resulting  from the growth  in operations and  increased
employee  levels.  Additionally,  in  the  six  months  ended  August  31, 1995,
amortization of goodwill  and intangibles increased  to $194,037, compared  with
$81,779  in  the six  months ended  August 31,  1994, reflecting  the additional
goodwill amortization resulting from acquisitions.
    

   
    Operating income in the six months ended August 31, 1995 increased 28.0%  to
$3,612,939,  compared with $2,823,538  in the six months  ended August 31, 1994.
Operating income  decreased as  a percentage  of revenues  to 16.1%  in the  six
months ended August 31, 1995, compared with 16.7% in the six months ended August
31, 1994.

    Nonoperating  expenses in  the six  months ended  August 31,  1995 increased
113.7% to $228,694  compared with $107,016  in the six  months ended August  31,
1994.  The increase in nonoperating expenses is primarily attributable to higher
interest expenses due to increased borrowings.
    

   
    Income tax expense  in the six  months ended August  31, 1995 was  $970,000,
compared with $1,046,000 in the six months ended August 31, 1994. The income tax
expense  reflects a  one-time benefit of  $350,000 resulting from  the merger of
Aurora into ATC  which will  allow ATC to  utilize Aurora's  net operating  loss
carryforwards  as offsets  to its future  taxable income. During  the six months
ended August 31, 1995, after adjusting for the one-time tax benefit, and the six
months ended August 31, 1994, the  Company's effective tax rates were 39.0%  and
38.5%, respectively.
    

   
    As  a result of the foregoing, net income in the six months ended August 31,
1995 increased 44.5% to $2,414,245, or $.38 per share on a fully diluted  basis,
compared  with $1,670,522 or $.30 per share on a fully diluted basis, in the six
months ended August 31, 1994. Excluding  the impact of the one-time tax  benefit
of  $350,000, net income  and fully diluted  earnings per share  would have been
$2,064,245 and $.33, respectively, for the six months ended August 31, 1995. The
fully diluted weighted  average number of  shares outstanding increased  796,230
shares  to 6,332,657 shares primarily due to  an increase in shares, options and
warrants outstanding as a result of  the Aurora Merger effective June 29,  1995,
the  exercise of the Class  B warrants and the  issuance of shares in connection
with the acquisition  of Con-Test. Net  income as a  percentage of revenues  was
10.7%  in the six  months ended August 31,  1995, compared with  9.9% in the six
months ended August 31, 1994.
    

  YEAR ENDED FEBRUARY 28, 1995 COMPARED WITH YEAR ENDED FEBRUARY 28, 1994

    Revenues in  fiscal  1995  increased 36.0%  to  $36,271,557,  compared  with
$26,664,385 in fiscal 1994. This increase was attributable to increased revenues
in ATC's existing branches and the positive effect of acquisitions.

    Revenues  in  fiscal  1995  from  ATC's  branch  offices  having  comparable
operations  in  fiscal  1994  increased  13.2%  to  $20,340,764,  compared  with
$17,965,654 in fiscal 1994.

    Revenues  in fiscal 1995  from operations resulting  from the acquisition of
assets of BSE Management, Inc. ("BSE") effective as of April 30, 1993  increased
42.8%  to $11,754,623, compared with $8,230,000 in fiscal 1994. Of these revenue
amounts,  $3,213,000  and   $1,560,000  for   fiscal  1995   and  fiscal   1994,
respectively,  were from the Corps for  asbestos management services. The fiscal
1995 data reflects 12 months of operations  from BSE while the fiscal 1994  data
reflects only 10 months of such operations.

    Revenues  from  operations  resulting  from the  acquisitions  of  assets of
Con-Test, MES,  and R.E.  Blattert, contributed  $4,176,170 in  fiscal 1995.  In
fiscal 1994, revenues of $468,731 and a net loss of $109,846 were contributed by
former  branch offices of Bio/West, Inc.  ("Bio/West"). The Company entered into
an agreement to  acquire Bio/West  on June  10, 1992;  however, the  acquisition
transaction was rescinded effective as of May 31, 1993.

   
    During  fiscal  1995,  ATC's revenues  benefitted  from  asbestos management
consulting and testing services provided to the  NYCSCA as part of its New  York
City  school construction and maintenance program.  Revenues in fiscal 1995 from
the NYCSCA increased  14.2% to  $3,859,595, compared with  $3,379,100 in  fiscal
1994.  As a percentage of revenues, revenues  from the NYCSCA decreased to 10.6%
in fiscal 1995, compared with 12.7% in fiscal 1994.
    

    Gross profit in fiscal  1995 increased 45.7%  to $17,916,064, compared  with
$12,294,424 in fiscal 1994. Similarly, gross margin increased to 49.4% in fiscal
1995,  compared with  46.1% in  fiscal 1994.  During fiscal  1995, ATC's margins
improved due to labor force efficiencies which were due in part to the  Con-Test
acquisition,  the acquisition  of certain assets  of BSE and  the integration of
certain of their operations with ATC's existing operations.

    Operating expenses in fiscal 1995  increased 35.5% to $12,291,465,  compared
with $9,067,881 in fiscal 1994. Operating expenses remained almost constant as a
percentage  of revenues at 33.9%  and 34.0% during fiscal  1995 and fiscal 1994,
respectively.  Employee  costs  increased  36.6%  to  $6,284,627,  or  17.3%  of

                                       17
<PAGE>
revenues,  in fiscal  1995, compared with  $4,599,951, or 17.3%  of revenues, in
fiscal  1994.  Other  increases  in  operating  expenses  resulted  from  higher
depreciation,  equipment and supply costs and travel expenses resulting from the
growth in operations and  increased employee levels. Additionally,  amortization
of goodwill and intangibles increased to $212,320 in fiscal 1995 from $37,716 in
fiscal  1994,  reflecting the  additional  goodwill amortization  resulting from
acquisitions. Facility costs  as a percentage  of revenues in  fiscal 1995  were
5.0%, compared with 6.0% in fiscal 1994.

    Operating income in fiscal 1995 increased 74.3% to $5,624,599, compared with
$3,226,543  in  fiscal  1994.  Operating income  increased  as  a  percentage of
revenues to 15.5% in fiscal 1995, compared with 12.1% in fiscal 1994.

    Nonoperating expenses in fiscal 1995 increased 116.8% to $324,079,  compared
with $149,495 in fiscal 1994. The increase in nonoperating expenses is primarily
attributable  to  higher  interest  expenses  due  to  increased  borrowings and
expenses of approximately $83,000 related to the Aurora Merger.

    Income tax expense in fiscal  1995 was $2,044,000, compared with  $1,210,000
in fiscal 1994. The Company's effective tax rates in fiscal 1995 and fiscal 1994
were 38.6% and 39.3%, respectively.

    As  a result of the foregoing, net  income in fiscal 1995 was $3,256,520, or
$.56 per share on a fully diluted  basis, compared with $1,867,048, or $.35  per
share  on a  fully diluted  basis, in  fiscal 1994.  The fully  diluted weighted
average number  of  shares outstanding  increased  453,860 shares  to  5,850,233
shares  primarily due  to the exercise  of the  Class B Warrants.  Net income in
fiscal 1995 increased as a percentage of revenues to 9.0%, compared with 7.0% in
fiscal 1994.

  YEAR ENDED FEBRUARY 28, 1994 COMPARED WITH FEBRUARY 28, 1993

    Revenues in  fiscal  1994  increased 61.2%  to  $26,664,385,  compared  with
$16,539,254 in fiscal 1993. This increase was attributable to the acquisition of
assets  of BSE and  the strong performance  of ATC's existing  branches, and was
partially offset by the rescission of the Bio/West purchase agreement.

    Revenues  in  fiscal  1994  from  ATC's  branch  offices  having  comparable
operations  in  fiscal  1993  increased  32.0%  to  $17,965,654,  compared  with
$13,614,964 in fiscal 1993. During fiscal 1994, ATC's revenues began to  benefit
from  its asbestos  management consulting and  testing services  provided to the
NYCSCA as part of its New York City school construction and maintenance program.
Revenues in  fiscal 1994  from the  NYCSCA  were $3,379,100  or 12.7%  of  total
revenues.

    Revenues  in fiscal 1994  from operations resulting  from the acquisition of
assets of BSE, contributed  $8,230,000. Of this  revenue amount, $1,560,000,  or
5.9%, was from the Corps for certain asbestos management services.

    Revenues  in fiscal 1994 from former  Bio/West branch offices were $468,731,
compared with $2,924,290 in fiscal 1993.

    Gross profit in fiscal  1994 increased 84.9%  to $12,294,424, compared  with
$6,649,642  in fiscal 1993. Similarly, gross margin increased to 46.1% in fiscal
1994, compared with  40.2% in  fiscal 1993.  During fiscal  1994, ATC's  margins
improved  primarily  due  to  labor  force  efficiencies  achieved  through  the
integration of  acquired  companies  and  the  rescission  of  its  purchase  of
Bio/West,  which historically operated at a lower gross profit margin than ATC's
other operations.

    Operating expenses in  fiscal 1994 increased  53.1% to $9,067,881,  compared
with  $5,922,120 in fiscal 1993. Operating expenses decreased as a percentage of
revenues in  fiscal 1994  to 34.0%,  compared with  35.8% in  fiscal 1993.  This
decrease  was achieved by integrating certain BSE operations with ATC's existing
branch operations.

    Operating income in  fiscal 1994  increased 343.5%  to $3,226,543,  compared
with  $727,522 in  fiscal 1993.  Operating income  increased as  a percentage of
revenues to 12.1% in fiscal 1994, compared with 4.4% in fiscal 1993.

                                       18
<PAGE>
    Nonoperating expenses in fiscal 1994 increased 101.0% to $149,495,  compared
with $74,378 in fiscal 1993. The increase in nonoperating expenses was primarily
attributable to higher interest expenses due to increased borrowings.

    Income  tax expense in fiscal 1994 was $1,210,000, compared with $300,000 in
fiscal 1993. The Company's  effective tax rates in  fiscal 1994 and fiscal  1993
were  39.3%  and 45.9%,  respectively. The  fiscal 1993  effective tax  rate was
higher than the fiscal 1994 rate because  the Company could not utilize the  tax
benefits  of the net operating losses of  Bio/West as a result of the rescission
of such transaction.

    As a result of the foregoing, net  income in fiscal 1994 was $1,867,048,  or
$.35  per share on  a fully diluted  basis, compared with  $353,144, or $.07 per
share on  a fully  diluted basis,  in fiscal  1993. The  fully diluted  weighted
average   number  of  shares  outstanding   increased  nominally  to  5,396,373.
Similarly, net income  in fiscal  1994 increased  as percentage  of revenues  to
7.0%, compared with 2.1% in fiscal 1993.

SEASONALITY

    ATC  typically experiences  a slow  down in  business activities  during the
winter months and an increase in  business activities during the summer  months.
This is due to seasonal fluctuations in construction and remediation activities.
Thus, operating results may vary from quarter to quarter.

   
LIQUIDITY AND CAPITAL RESOURCES
    

   
    At  August 31, 1995,  working capital was  $11,233,641 compared with working
capital of $8,113,738  at February  28, 1995,  an increase  of $3,119,903.  This
increase  in  working capital  is primarily  a result  of ATC's  acquisitions of
current assets  of R.E.  Blattert  and MES,  increases  in billed  and  unbilled
receivables  and the reduction of current liabilities using long-term borrowings
under the Company's revolving credit facility with the Atlantic Bank of New York
("Atlantic"). At February 28, 1995 working capital was $8,113,738 compared  with
working  capital of $6,049,013 at February  28, 1994, an increase of $2,064,725.
This increase in working capital is, in  part, a result of ATC's acquisition  of
certain assets of MES and Con-Test.
    

   
    During  the  six  months ended  August  31,  1995, net  cash  flows  used in
operating activities were $1,727,473, primarily due to an increase in billed and
unbilled receivables. Net cash flows used in investing activities were $896,436,
resulting  from  the  Con-Test   and  R.E.  Blattert  acquisitions,   additional
contingent  purchase  obligations in  connection  with the  BSE  acquisition and
purchases of  property  and equipment.  Net  cash flows  provided  by  financing
activities  were $1,710,207, primarily representing  proceeds from an $2,175,000
increase  in  outstanding  debt  under  the  Company's  credit  facilities  with
Atlantic, less payments made on long-term debt and notes payable of $499,159.
    

   
    During  the six  months ended  August 31, 1994,  net cash  flows provided by
operating  activities  were  $1,673,844.  Net  cash  flows  used  in   investing
activities  were  $888,476  consisting  of the  payment  of  contingent purchase
obligations related to the acquisition of  BSE and the purchase of property  and
equipment.  Also during this period, net cash flows used in financing activities
were $1,547,907, primarily for  principal payments on  long-term debt and  notes
payable  of $2,100,448  which were  offset by  proceeds from  issuance of common
stock of $617,285.
    

   
    During fiscal 1995,  net cash  flows provided by  operating activities  were
$3,030,703.  Net  cash  flows  used  in  investing  activities  were $4,099,812,
consisting primarily of the purchase of certain assets of BSE, Con-Test and MES,
and property and equipment. Also during this period, net cash flows provided  by
financing activities were $1,052,082, primarily from the exercise of ATC's Class
B  Warrants and  borrowing under  the Company's  revolving credit  facility with
Atlantic. These  sources of  cash  were reduced  by principal  debt  repayments,
including payments of $1,961,000 with respect to bank debt assumed in connection
with the Con-Test and R.E. Blattert acquisitions.
    

   
    During  fiscal  1994,  net  cash flows  used  in  operating  activities were
$28,653. Net cash flows used in investing activities were $1,476,300,  primarily
to purchase certain assets of BSE and property and equipment. These uses of cash
were partially offset by cash received related to the rescission of the Bio/West
    

                                       19
<PAGE>
   
purchase  agreement.  Net  cash  flows  provided  by  financing  activities were
$1,835,002, resulting from  the proceeds  of notes payable  and long-term  debt,
partially  offset by the principal payments on long-term debt, including capital
lease obligations of $1,174,756.
    

   
    During fiscal 1993,  net cash  flows provided by  operating activities  were
$602,583.  Net cash flows used in  investing activities were $291,656, resulting
from the purchase of certain assets of Bio/West and property and equipment,  and
the partial offset by proceeds from maturity of investments. Net cash flows used
in  financing activities were $157,250, as a result of the principal payments on
long-term debt including capitalized lease obligations of $400,292.
    

   
    In fiscal 1995, ATC increased its revolving credit facility with Atlantic to
$5,000,000. The note underlying  ATC's credit facility  with Atlantic, which  is
currently  due September  30, 1996 (the  "Note"), provides that  Atlantic is not
obligated to make loans to ATC if doing so would cause the aggregate outstanding
principal amount  of all  loans under  the  Note to  exceed the  borrowing  base
prescribed  in the Note. The  Note contains certain representations, warranties,
affirmative covenants,  negative covenants  and financial  covenants. Events  of
default  under the Note include, but are not  limited to, a change in control of
ATC or any  guarantor. As  of the  date hereof, ATC  is in  compliance with  all
covenants under the Note, with advances of $5,000,000 outstanding at October 10,
1995.  Although the  Company intends to  use a  portion of the  proceeds of this
offering to repay in full the outstanding debt under its credit facilities,  the
Company intends to maintain a revolving credit facility following this offering.
    

   
    During  the second  quarter of fiscal  1996 the Company  extended its credit
facility with Atlantic to provide an  additional $500,000 in borrowings, all  of
which was outstanding at September 30, 1995. These additional borrowings are due
October 31, 1995.
    

   
    The Company's working capital and liquidity will increase substantially upon
receipt  of  the  net  proceeds from  this  offering.  Management  believes that
following this offering ATC's working capital, available credit and  anticipated
funds  generated internally from operations and this offering will be sufficient
to finance ATC's anticipated growth through acquisitions and internal expansion,
to make payments as they  come due on ATC's  completed acquisitions and to  meet
ATC's short-term and long-term liquidity requirements.
    

   
    ATC  may open  additional offices  in the  future at  presently undetermined
sites based upon potential sales growth  and upon a determination of whether  or
not  an office can  meet Management's profitability  objective. In addition, ATC
has added regional offices in the recent  past as a result of the completion  of
certain  acquisitions and may add additional offices through acquisitions in the
future. As of the date of this Prospectus, ATC has no definitive agreements  for
new office expansion or any material acquisition.
    

   
    On  March  1, 1996,  the  Company intends  to  adopt Statement  of Financial
Accounting  Standards  ("SFAS")  No.  121,  ACCOUNTING  FOR  THE  IMPAIRMENT  OF
LONG-LIVED  ASSETS  AND  FOR LONG-LIVED  ASSETS  TO BE  DISPOSED  OF. Management
anticipates the adoption of SFAS No. 121 will not have a material effect on  the
Company's financial statements.

OVERVIEW

    ATC  is  a  national  environmental  consulting  and  engineering  firm that
provides specialized technical and project management products and services to a
large,  diverse  client  base  of  businesses  and  federal,  state  and   local
governments.   Since  entering  the  environmental  consulting  and  engineering
business in  1982,  ATC has  completed  several acquisitions  and  expanded  its
internal  operations, enabling  it to  increase its  market penetration  and the
variety of products  and services it  offers. The Company  currently operates  a
network  of  over  30  branch  offices  located  throughout  the  United States,
supported by in-house testing laboratories.

    The public's concern regarding exposure to contaminants stimulated the  push
for  environmental  regulations  in the  1970s  and 1980s.  Today,  the public's
continuing demand for responsible action  regarding human health and safety  and
the  potential adverse impact of environmental  liabilities drive the market for
environmental  consulting   and  engineering   services.  Independent   industry
estimates of the consulting and engineering services sector of the environmental
market  for 1994 ranged from $13 to $15 billion, with annual growth projected at
5% to 8% through the next three to four years.

    ATC has  focused on  five areas  of specialization:  (i) industrial  hygiene
consulting,  including  asbestos  management, classical  industrial  hygiene and
indoor air  quality;  (ii)  environmental  management,  including  environmental
audits,  site assessments,  remedial action  planning and  design, and  soil and
groundwater remediation management; (iii) lead-based paint risk management; (iv)
health and safety  consulting, including health  and safety training,  hazardous
materials  site  safety  planning  and  industrial  safety  consulting;  and (v)
management information systems for  comprehensive environmental risk  assessment
and  management. These  areas of  specialization contributed  approximately 65%,
19%, 10%, 5% and 1%, respectively, of the Company's revenues in fiscal 1995.

    The Company believes  that certain sectors  of the environmental  consulting
and  engineering market will experience significant growth over the next several
years with  demand for  products and  services growing  even in  the absence  of
increased  governmental regulations. Independent industry sources project annual
growth rates  of  10%,  13%,  15%  and  20%  for  lead-based  paint  management,
occupational   safety  and  industrial  hygiene  services,  indoor  air  quality
consulting and environmental software, respectively.

    The Company has experienced substantial increases in revenues and net income
over the past three fiscal  years. ATC's revenues were $16,539,254,  $26,664,385
and  $36,271,557,  respectively,  in  its  1993,  1994  and  1995  fiscal years,
representing a  compounded  annual  growth  rate of  48.1%  over  such  periods.
Furthermore,   ATC's  net  income  was   $353,144,  $1,867,048  and  $3,256,520,
respectively, in such fiscal years, representing a compounded annual growth rate
of 203.7% over  such periods. For  the Company's first  fiscal quarter of  1996,
revenues  increased 32.4%  to $10,814,953 over  the comparable  period of fiscal
1995, while net income increased 29.8% to $895,128.

    ATC attributes these positive operating  results to its integrated  strategy
which  includes: (i) an  aggressive, but disciplined,  acquisition program; (ii)
the enhancement of  operations through  the integration  of acquired  businesses
with  the Company's existing operations; (iii)  a focus on certain higher growth
sectors of the  environmental consulting  and engineering  services market,  and
certain  higher margin services such as policy development and decision support;
(iv)  an  emphasis  on  basic  business  management  issues,  such  as  employee
utilization,  credit  and  collections management,  and  regional  profit center
accountability; and  (v) the  development of  a national  presence in  a  market
typified  by local and regional firms. Upon the completion of this offering, the
Company intends to  employ this strategy  as it seeks  to further penetrate  the
markets  for its core services and to  expand its range of products and services
through strategic acquisitions and internal growth.

THE ENVIRONMENTAL CONSULTING AND ENGINEERING SERVICES INDUSTRY

    During the 1980s,  the market for  environmental consulting and  engineering
services grew significantly, due in part to a high level of federal expenditures
and stringent regulations mandating actions to identify and

                                       21
<PAGE>
mitigate  asbestos hazards,  hazardous waste  sites, industrial  emissions and a
host of other concerns. The industry's growth  slowed in the early 1990s as  the
industry was adversely effected by a down turn in the national economy.

    Presently,  the  industry is  viewed  as having  stabilized,  with declining
demand in  some sectors  being offset  by  growth in  others. According  to  two
independent  market  evaluations,  one  by  THE  ENVIRONMENTAL  BUSINESS JOURNAL
("EBJ") and the other by the independent  marketing firm of Richard K. Miller  &
Associates,  Inc.  ("RKM&A"),  the  size  of  the  environmental  consulting and
engineering services  market for  1994  was estimated  at  between $13  and  $15
billion, with annual growth projected at 5% to 8% through the next three to four
years.

    Although estimated growth rates for the industry over the next few years are
well  below  the growth  rates experienced  in  the industry  in the  1980s, the
Company believes  that for  the next  few years  growth in  demand from  private
sector  clients and in certain service areas will exceed the average growth rate
of the overall industry. These service areas include lead-based paint management
and indoor air quality  consulting services, which  RKM&A estimates to  increase
10%  and 15%,  respectively. RKM&A  estimates that  the occupational  safety and
industrial hygiene sectors of the market will grow at an average annual rate  of
13%  and that  environmental software services  will increase  20% annually. The
Company believes risk analysis services will also emerge in response to a desire
for closer matching of limited  clean up funds with  the problems that are  most
serious.

    Industry  observers believe that the asbestos market will show little growth
and the hazardous  waste services  market will  experience some  decline in  the
coming years. The current sizes of these markets, however, are $3 billion and $6
billion, respectively, and the Company believes that based on the sizes of these
markets  and current clean  up rates, these markets  will remain significant for
the  next  several  years.  Furthermore,  while  governmental  expenditures  are
expected to evidence slower growth in the coming years as a result of changes in
political  priorities,  private  sector spending  on  environmental  services is
expected to increase, particularly in certain sectors.

    Notwithstanding the recent  public discourse  concerning regulatory  reform,
new regulations have been promulgated which the Company believes will create new
business  opportunities in certain  sectors of the  environmental consulting and
engineering services industry. In February 1994, the United States Department of
Labor promulgated new asbestos regulations  for the construction industry  which
are  more stringent than  the previous regulations.  Lead-based paint is another
area of increasing regulatory activity, partially in response to the  provisions
of  Title X of the Housing and  Community Development Act of 1992, and partially
as a result  of increasing concern  arising from evidence  of the severe  health
effects of childhood lead poisoning.

    While  the  historical growth  in  environmental consulting  and engineering
services has  been stimulated  by regulatory  compliance concerns,  the  Company
believes  that  future  growth  will,  in  large  part,  be  driven  by  private
litigation, asset  preservation and  productivity considerations.  As  companies
have  become  increasingly sensitive  to the  potential adverse  consequences of
environmental problems and  the potential impact  of environmental  liabilities,
they  have taken an active approach  to managing environmental health and safety
risks and liabilities, whether or not the subject of regulations. This trend  is
currently  being observed in such areas  as steel structure repainting projects,
real estate transactional assessments and indoor air quality initiatives.

    Bridge and tunnel  authorities undertaking the  removal of lead-based  paint
from  large  steel structures  are seeking  to  establish monitoring  systems to
prevent the dispersion of lead dust  into the environment. The Company  believes
that  such  actions  are  motivated  in large  part  by  concerns  regarding the
potential liabilities associated  with lead  contamination. Similarly,  concerns
over  environmental  risks  have  made  environmental  assessments  an  integral
component of the  due diligence process  for commercial transactions.  Financial
institutions   frequently  require  environmental   assessments  prior  to  loan
originations and foreclosure activities, while insurance companies  increasingly
require   environmental  assessments  before   issuing  environmental  insurance
liability policies. Another industry segment that is experiencing growth even in
the absence of

                                       22
<PAGE>
extensive regulation is indoor air quality.  Indoor air quality is viewed as  an
important   environmental   concern  which   may  significantly   impact  worker
productivity. Published estimates  of productivity  losses as a  result of  poor
indoor air quality range from $40 to $50 billion per year in the United States.

    Many governmental agencies and businesses are looking at risk-based analysis
as the new model for decision-making instead of rote application of rigid rules.
This  trend presents new service  opportunities for the environmental consulting
and engineering services  industry in several  areas from which  the Company  is
positioned  to benefit. The  absence of adequate  funding to immediately address
the full  cost of  clean ups  requires  the employment  of risk  assessment  and
planning  techniques  that direct  funding  toward the  problems  presenting the
highest levels of risk. In addition, RKM&A sees a trend toward "outsourcing"  of
environmental   functions   by   corporations.   Under   outsourcing  contracts,
environmental consulting  firms function  as  the environmental  departments  of
large   corporations.  The  Company   views  outsourcing  as   a  future  growth
opportunity.

STRATEGY

    The Company's  integrated strategy  focuses on  increasing revenues  through
acquisitions  and internal growth by promoting its core services and introducing
new and  innovative  services  while  continuing  to  achieve  profitability  in
existing   and  acquired  operations  through  the  implementation  of  rigorous
financial and operational controls. Through strategic acquisitions, the  Company
has  been able to increase the variety of  services that it offers and develop a
nationwide network  of  offices and  facilities  capable of  servicing  national
accounts.

    ATC's acquisition strategy includes identifying target companies in specific
geographical  areas  in which  ATC does  not  have a  strong presence  or target
companies with new, transferable technologies or exploitable areas of expertise.
The environmental consulting and engineering services market is fragmented, with
over 3,600  environmental consulting  and engineering  companies in  the  United
States,  of which only 31 have over $100 million in annual sales. There are many
specific  service  specialties,  many  small-sized  companies  and  thus,   many
potential  acquisition  candidates.  Acquisitions  can  lead  to  bi-directional
technology transfers  with  the acquired  company's  services offered  to  ATC's
existing  client base and ATC's core services offered to clients of the acquired
company. Furthermore,  when  acquisitions  are located  close  to  existing  ATC
branches, economic consolidations are frequently possible.

    In  recent  years, the  Company has,  through  the acquisitions  of Dennison
Environmental, Inc.  ("Dennison")  and  Con-Test, entered  two  of  the  fastest
growing  sectors  of  the  environmental  consulting  and  engineering  services
industry, lead-based paint  risk management and  management information  systems
and  services.  The  Company believes  that  in  many cases,  like  Dennison and
Con-Test, opportunities exist  to improve  the historical  operating results  of
acquired  companies by:  (i) reducing  general and  administrative costs through
consolidating facilities,  reducing  administrative personnel  costs,  improving
purchasing power and taking advantage of other economies of scale; (ii) reducing
costs  of sales  by decreasing reliance  on subcontractors;  and (iii) improving
financial and operational control systems.

    The Company believes that its positive operating results in recent years are
due, at least in part,  to its disciplined approach  to the management of  basic
business  fundamentals.  ATC's  professional administrative  staff  monitors and
oversees the financial and administrative functions of the business. ATC strives
to manage  profit  center accountability  through  a combination  of  goals  and
incentives and performance monitoring.

SERVICES AND PRODUCTS

    The  Company provides  a range  of specialized  environmental consulting and
engineering  services,  including  asbestos  management,  classical   industrial
hygiene,   lead-based  paint  risk  management,   health  and  safety  training,
environmental audits,  remedial  action  planning, design  and  management,  and
comprehensive  environmental  risk  assessment  and  management.  The  Company's
services are offered  individually or  together as  part of  the Company's  full
service approach to environmental consulting. During the first fiscal quarter of
1995,  ATC  provided services  to  over 1,000  clients  ranging from  small site
investigations to  large  comprehensive assessment  and  remediation  management
projects.

                                       23

  INDUSTRIAL HYGIENE

    The  Company offers a  variety of industrial  hygiene services which include
asbestos management, classical industrial  hygiene investigations and  analyses,
indoor air quality services and laboratory services.

    ASBESTOS  MANAGEMENT.    ATC  provides  comprehensive  asbestos  testing and
consulting services. These  services may begin  with a survey  of facilities  to
determine  the  condition,  type,  quantity  and  location  of  asbestos.  After
gathering field samples, the Company utilizes polarized light microscopy,  phase
contrast  microscopy and  transmission electron  microscopy to  analyze asbestos
fibers. Other services include risk assessment, remediation design for  asbestos
abatement,  industrial hygiene  services before,  during and  after the asbestos
removal process, development of operations and maintenance training programs for
facilities personnel,  development of  operations and  maintenance programs  for
custodial  and maintenance personnel, and  providing asbestos awareness seminars
for client personnel.

    ATC's services  are designed  to  enable building  owners and  operators  to
comply  with  federal,  state and  local  regulations for  asbestos  control, by
providing a comprehensive approach for  controlling or removing asbestos.  ATC's
technical  personnel  include  registered  architects,  professional  engineers,
certified industrial  hygienists, certified  safety professionals  and  asbestos
specialists,  with  extensive  experience  managing  hazardous  materials.  Such
personnel are licensed and certified by federal, state and local agencies.

    CLASSICAL INDUSTRIAL HYGIENE.   ATC  evaluates potential  health hazards  in
occupational  settings,  including  physical hazards  and  hazards  arising from
exposure  to  chemical  or  biological  substances.  Potential  hazards  include
solvents,  corrosive chemicals,  gases, toxic  dusts, radiation,  lasers, noise,
lighting, heat, bacteria and molds. Evaluations determine the extent of exposure
to  potentially  hazardous  substances  and  methods  to  control  and  minimize
associated  risks. Field measurements are evaluated to determine compliance with
governmental regulations  and other  standards.  After corrective  measures  are
designed  and implemented, ATC provides  follow-up monitoring designed to ensure
that workplace exposures have been minimized.

    INDOOR AIR  QUALITY.    Healthy  indoor air  quality  is  recognized  as  an
essential  factor in promoting comfort  and welfare. ATC provides investigations
designed to  identify:  (i) sources  of  indoor  air pollution;  (ii)  route  of
exposure  to individuals; (iii) route of entry  into the body; and (iv) possible
effects on occupants. The investigatory process typically includes interviews of
occupants and  air monitoring  of  indoor and  outdoor ambient  environments  to
evaluate   exposures,  symptoms   and  concerns.  A   thorough  building  system
investigation evaluates  mechanical and  ventilation  systems which  may  impact
habitable  space. An inventory of chemicals, air contaminants, office equipment,
plants,  water  sources  and  other  potentially  harmful  substances,   process
equipment  and maintenance practices  may also be part  of the evaluation. After
completing a facility evaluation, ATC  recommends solutions that are  customized
to the specific facility and problem.

    LABORATORY  SERVICES.   ATC maintains analytical  testing laboratories which
provide  analyses  of  a  wide   spectrum  of  materials,  including   suspected
asbestos-containing materials, suspected lead-based paint substances, industrial
and  municipal waste water, air and certain hazardous wastes. These laboratories
support ATC's consulting and remediation  management services, and also  operate
independently.   ATC's  operations  incorporate   chain-of-custody  and  quality
assurance procedures and professionally recognized laboratory practices.

  ENVIRONMENTAL MANAGEMENT

    ATC's  environmental   management   services  range   from   real   property
investigations  for environmental contamination,  to turn-key remediation. These
services can include soil and ground water analysis, installation of  monitoring
wells,  recovery system design, regulatory  permitting, contractor selection and
remediation oversight.  Financial  institutions,  as  well  as  certain  states,
mandate  pre-purchase or pre-loan real  property environmental assessments prior
to property transfer, closure or sale. An environmental audit by ATC can help to
detect the presence  of pollutants and,  in some cases,  to determine costs  for
clean up.

    GROUNDWATER  ASSESSMENTS.  At  sites where the quality  of groundwater is in
question, due  to  a  confirmed  or suspected  spill  or  release  of  hazardous
substances,  ATC performs  assessments to  identify the  depth to  static water,
define pressure zones  or confining  conditions, determine  gradient and  sample
groundwater.

                                       24
<PAGE>
Once   analytical  results  are  known   and  soil  and  groundwater  conditions
established, ATC's  hydrologists,  geologists  and engineers  analyze  the  data
through  the use of predictive tools such as groundwater models to determine the
movement and ultimate destination of the contaminants.

    SITE   ASSESSMENTS   AND   CHARACTERIZATIONS.       Site   assessment    and
characterization  investigations  involve  defining the  important  physical and
chemical parameters  of  a  contaminated  site. A  site  assessment  provides  a
baseline  for understanding  subsurface conditions  and is  necessary before any
clean up can be designed or implemented.

    GROUNDWATER AND SOIL  REMEDIATION MANAGEMENT.   ATC's  services include  the
management  and oversight of clean  up projects through the  use of a variety of
diverse traditional and innovative  technologies including bioremediation,  land
farming,  soil  venting, air  sparging, pump  and  treat, and  thermal oxidation
systems.  ATC's   management   services   can   include   testing,   scheduling,
coordination,  documentation and approval of  progress payments, and interaction
with regulatory agencies throughout the life of the project.

  LEAD RISK MANAGEMENT

    Lead in paint,  drinking water  and soil  is a  major environmental  problem
facing  the United States. Lead  has no known useful  function in the human body
and is known to be toxic to virtually all organs in the body, even at relatively
low doses. In children,  excessive exposure to lead  can result in brain  damage
leading  to  learning  disabilities  and,  in  some  cases,  retardation.  Adult
exposures to excessive amounts of lead can cause reproductive, hematological and
nervous system disorders.

    As the first state-accredited lead risk management training institute in the
nation, ATC  was  one of  the  first companies  to  provide national  lead  risk
management   services.  Furthermore,  ATC  co-authored   and  edited  the  first
comprehensive textbook  on lead  risk management.  ATC is  a co-founder  of  the
National  Lead  Abatement  Council, the  first  trade  organization representing
contractors, inspectors,  vendors, attorneys  and  public officials  engaged  in
managing  lead risks. ATC maintains a  high degree of visibility and credibility
in the lead services arena  through participation in professional and  consensus
standard   setting  organizations  and  through  publishing  articles  in  trade
publications.

    Until recently,  lead  risk management  services  were sought  primarily  to
establish  compliance with  lead poisoning prevention  regulations. However, the
market is now expanding  as clients increasingly  seek voluntary risk  reduction
programs and defend against a proliferation of lead poisoning lawsuits.

   
    Federal  law requires  lead paint testing  of all  federally assisted public
housing authority  projects nationwide,  and the  full lead  paint abatement  of
these  projects.  ATC  has provided  lead  paint testing  and  abatement project
management services to numerous public housing authorities throughout the United
States. As this work proceeds, ATC is also pursuing opportunities created by two
new federally funded  programs. The first  program authorized approximately  $25
million  of federal grants to public  housing authorities to conduct specialized
lead hazard  risk  assessments  and  develop  property  management  programs  to
maintain  "lead-safe" dwellings until  such time that lead  paint can be abated.
The second program authorized  approximately $279 million  of federal grants  to
state  and local regulatory agencies to conduct innovative lead paint inspection
and abatement.  ATC has  identified and  is aggressively  marketing the  grantee
agencies.
    

    Additional  opportunities are presented by federal regulations under Title X
of the Housing and Community Development Act of 1992 which, among other  things:
(i)  established a  national requirement for  training and  certification of all
lead contractor  workers and  supervisors, inspectors,  risk assessors,  project
designers  and other  individuals involved  in lead  paint activities;  and (ii)
established new disclosure requirements applicable to all property  transactions
affecting residential properties built prior to 1978.

    ATC's  lead management  services are  broadly categorized  as: (i) corporate
lead risk management  services; (ii) steel  structure and industrial  compliance
services;  and  (iii)  residential  lead paint  testing  and  project management
services.

                                       25
<PAGE>
    CORPORATE LEAD RISK MANAGEMENT SERVICES.   ATC provides corporate lead  risk
management programs, primarily to insurance companies, lending institutions, law
firms  and large  real estate  managers. ATC's  services enable  corporations to
effectively address lead-related liabilities  by advising these institutions  in
their  development  and  implementation  of lead  risk  management  policies and
procedures.

    Policy development  typically  entails an  examination  of a  client's  real
estate  with  respect  to  potential  lead  liabilities.  Working  closely  with
corporate legal and technical divisions, ATC recommends policies and  procedures
to ensure lead-safe management of properties and compliance with applicable lead
poisoning  prevention  regulations.  ATC  also  designs  and  implements special
studies or demonstration programs to  provide empirical data for validating  the
efficacy   of  property  management  guidelines.  ATC's  policy  recommendations
therefore include  provisions  for clients  to  anticipate, guard  against,  and
effectively  respond  to lead  poisoning  complaints, regulatory  violations and
lawsuits.

    The Company's corporate lead risk management services include designing  and
implementing compliance training seminars and workshops tailored to the needs of
the  different  program  participants.  ATC's  corporate  training  programs are
periodically revised to reflect changes in accepted work practices.

    ATC offers lead paint litigation support services exclusively in support  of
property  owners, managers,  lending institutions  and insurers.  These services
include case consultation, regulatory analysis, document and deposition  review,
expert testimony, as well as site investigation and testing services.

    STEEL STRUCTURE AND INDUSTRIAL COMPLIANCE SERVICES.  Nationwide, hundreds of
thousands  of petroleum storage  tanks, water tanks,  transportation bridges and
other major structures are  made of steel and  painted with coats of  lead-based
paints  and  leaded  primers.  These  structures  require  periodic maintenance,
including full removal of the leaded  paints and primers followed by  re-priming
and re-painting to prevent them from corroding.

    ATC  provides comprehensive environmental  monitoring of surface preparation
activities that include the removal of  lead and associated coatings from  steel
structures.  ATC  employs trained  engineers and  has  the expertise  to prepare
abatement specifications and guide  agencies, engineers and contractors  through
lead  removal  activities  in  accordance  with  all  federal,  state  and local
regulations. ATC prepares  and has submitted  numerous environmental  monitoring
and sampling protocols to assist in protecting the public community, workers and
the  environment  from  potential  contamination  resulting  from  lead  removal
activities.

    RESIDENTIAL SERVICES.  ATC provides residential property owners and managers
with services for the analysis of lead  in paint, soil, air and drinking  water.
Consultation  services include surveys to identify lead problems, to design safe
and responsible procedures  for the removal  of lead paint  and to control  lead
dust  and contaminated  debris while reducing  clean up costs.  ATC provides the
necessary detailed specifications  where exterior and  internal surfaces  coated
with  lead paint must be abated. ATC also designs worker health and safety plans
for lead  removal  activities,  and provides  construction  monitoring  of  lead
projects to prevent occupant, worker and third-party exposure to lead dust.

  HEALTH AND SAFETY

    The  Company has established several health and safety training and advisory
programs.

    EDUCATION AND TRAINING.   ATC operates training schools  under the name  The
Environmental  Institute, as  well as under  ATC Environmental  Inc. The Company
develops and presents public  and private training courses  each year for  those
involved  in environmental, asbestos,  lead, hazardous materials  and safety and
health issues.  "Right-to-Know"  programs in  accordance  with mandates  by  the
federal  Occupational  Safety and  Health  Administration ("OSHA"),  the federal
Environmental Protection Agency ("EPA") and some state regulations are  designed
to  communicate information  regarding the hazards  of chemicals  to workers and
communities. Instructors present practical, comprehensive courses, many of which
feature "hands-on" training. ATC routinely  customizes courses to meet  specific
client needs.

    HEALTH AND SAFETY CONSULTING.  ATC's occupational health and safety programs
enable  employers  and  property  owners  to  meet  or  exceed  the requirements
established by federal, state or local regulations,

                                       26
<PAGE>
particularly OSHA regulations.  A review  of work  practices can  result in  the
recognition,  evaluation and design of proper  safe work policies and procedures
to minimize or eliminate work-related injuries and illnesses.

    SITE SAFETY, HEALTH AND EMERGENCY RESPONSE PLAN.  ATC offers a full range of
technical support services for site-specific safety and health programs required
for hazardous waste operations. Employers that are subject to OSHA standards for
hazardous waste operations utilize ATC to provide assistance in many areas.

  MANAGEMENT INFORMATION SYSTEMS AND RISK MANAGEMENT

    The assessment of environmental liability involves the identification of the
liability, the development of an optimal response and the quantification of  the
cost  of the response.  An environmental hazard situation  usually does not have
only one possible response  alternative, but rather  a variety of  alternatives.
ATC  offers a variety of  products and services to  assist in the performance of
these functions.

    COMPREHENSIVE ENVIRONMENTAL MANAGEMENT  SYSTEM.  ATC  has developed  various
environmental facilities management software modules. These modules are marketed
to  current and prospective clients and are also used in ATC's branch locations.
The modules are designed to function  as the prime environmental database for  a
company's  facilities.  This software  can be  used to  keep track  of scheduled
environmental responses  and  to  maintain training  for  personnel  whose  jobs
involve environmental response or exposure to environmental hazards. The modules
can  also  be  used to  establish  audit  trails of  environmental  responses to
emergencies for  regulatory  agencies  and  ease  the  burden  of  environmental
compliance reporting and manage the client's exposure to liabilities.

    There  are seven different  modules that are  currently available: asbestos,
lead   paint,   storage   tanks,    hazardous   materials,   hazardous    waste,
training/certification  and environmental  compliance. Each of  these modules is
presently available for MS DOS-TM-  operating systems and several are  currently
available for use under MS Windows-TM- or MS Windows 95-TM- environments.

    RISK   MODELING/RISK  ASSESSMENT.     ATC   provides  decision   support  by
quantitatively analyzing  the risk  associated with  the outcomes  of  differing
environmental  responses. ATC can also provide computerized modeling to simulate
complex, uncertain decision scenarios by combining experience in proven risk and
economic risk analysis with its core expertise in a wide range of  environmental
hazard areas.

    CUSTOM  SYSTEM DESIGN AND IMPLEMENTATION.   ATC offers customized design and
implementation services in conjunction with object based development tools in  a
client/server architecture to develop custom computer systems.

CLIENTS AND MARKETING

    The Company provides its services to Fortune 500 companies, small companies,
real  estate property  managers and  federal, state  and local  governments. The
Company relies on  referrals from  existing and former  clients, architects  and
engineers  for a  large portion  of its contract  leads. The  Company performs a
substantial amount of repeat business for certain large companies and government
entities. The  Company's contracts  are obtained  by the  Company's sales  force
through a bidding process and other forms of engagement.

    Consistent  with trends towards  focusing on litigation,  liability and cost
control management, there is  an increasing tendency for  companies to obtain  a
greater  share of their environmental consulting and engineering services from a
smaller number of larger providers. This trend is evidenced by findings reported
in EBJ that  revenues for  the largest  environmental consulting  firms grew  at
almost  twice the industry  average during 1994. RKM&A  attributes this trend to
such issues  as the  greater insurance  protection and  indemnity coverage  that
larger  firms  can provide.  The  Company believes  that  this trend  presents a
significant opportunity for  firms, such  as ATC,  that have  the technical  and
financial  resources to both perform the  services and provide the insurance and
indemnity protection demanded by large corporate and government clients.

    To take  advantage of  this trend,  ATC's overall  marketing strategy  is  a
combined national and regional approach. National efforts are directed by senior
professionals of the Company, while regional efforts are

                                       27
<PAGE>
   
typically  directed either by  a regional or  branch manager, or  by a sales and
marketing professional. ATC currently has 24 individuals devoted exclusively  to
sales  and marketing  activities in  its offices  across the  United States. The
Company's regional  sales  and  marketing departments  generate  leads,  act  as
proposal  administrators, perform  technical writing  and generally  support the
Company's sales efforts.
    

    ATC presently markets its environmental consulting and engineering  services
through  its network of branch offices located in 22 states. The Company intends
to establish additional  offices within  the continental  United States.  Direct
marketing  is  accomplished by  technical  sales representatives,  technical and
management personnel  who  call  on  prospective clients.  ATC  also  relies  on
telemarketing,   direct  mail  solicitation,   national  trade  advertising  and
submission of competitive  bids for  potential governmental  projects listed  in
industry  publications.  In  addition,  ATC  markets  its  services  through its
environmental seminars and training courses for existing and potential clients.

COMPETITION

    The environmental consulting and engineering services industry is subject to
intense competition.  In  addition to  the  thousands of  small  consulting  and
testing   firms  operating  nationally,  ATC   competes  with  several  national
environmental engineering and  consulting firms such  as Law Engineering,  Inc.,
The  Earth Technology  Corporation (USA), Dames  & Moore,  Inc. and Professional
Service Industries, Inc. Many of ATC's  present and future competitors may  have
greater  financial,  technical  and  personnel resources  than  ATC.  It  is not
possible to predict the  extent of competition which  ATC will encounter in  the
near  future as the  environmental consulting and  engineering services industry
continues to mature  and consolidate. Historically,  competition has been  based
primarily  on the quality, timeliness and costs  of services. The ability of ATC
to compete successfully will depend upon  its marketing efforts, its ability  to
accurately  estimate costs, the quality of the  work it performs, its ability to
hire and train qualified personnel and the availability of insurance.

ENVIRONMENTAL REGULATION

    Most environmental  laws and  regulations are  promulgated by  Congress  and
departments  and  agencies  of  the  federal  government.  Many  of  the federal
regulations contemplate enforcement by state agencies and adoption by the states
of similar  regulations which  must meet  the minimum  federal requirements.  In
areas  of environmental law  where federal regulation is  silent, the states may
adopt their  own environmental  laws.  Local governments  such as  counties  and
municipalities  may also enact and enforce environmental laws that address local
concerns.

    Additionally, in  its  operations, ATC  and  its employees  are  subject  to
various regulatory, certification and licensing requirements.

    Those  federal agencies whose regulations,  guidelines or standards have the
greatest potential impact on ATC are:

    THE UNITED  STATES  DEPARTMENT  OF  LABOR--OCCUPATIONAL  SAFETY  AND  HEALTH
ADMINISTRATION, which requires particular work practices, sets limits for worker
exposure  on  the job,  requires employers  to  provide employees  with personal
protective devices  such  as respirators,  and  requires employers  to  maintain
records for periods of up to 30 years;

    THE  UNITED  STATES  ENVIRONMENTAL  PROTECTION  AGENCY,  which,  through its
National Emissions Standards for Hazardous Air Pollutants, regulations  requires
that  it be  notified of asbestos  removal or disturbance  during renovation and
demolition projects and requires specific  work practices at such projects,  and
which  through other statutes and regulations regulates a very broad spectrum of
industrial and commercial activities, including the disposal of hazardous waste;

    THE UNITED STATES DEPARTMENT OF HOUSING AND URBAN DEVELOPMENT ("HUD"), which
sets the  standards for  the  testing and  remediation  of lead-based  paint  in
publicly  funded housing, and which  provides funding for housing rehabilitation
including lead-based paint remediation; and

                                       28
<PAGE>
    THE UNITED STATES  DEPARTMENT OF TRANSPORTATION,  which regulates  packaging
and  transportation  of  hazardous  waste  by all  who  transport  or  cause the
transport of hazardous waste.

    The EPA, OSHA  and HUD  have each  published regulations  and guidelines  to
safeguard  employees and public occupants  from certain environmental exposures.
Federal regulations  specify work  practices for  removal of  asbestos and  lead
containing  materials  from  buildings.  Federal  law  also  presently  requires
employers to  inform workers,  and in  some places  the general  public, of  the
dangers   connected   with   hazardous  chemicals   in   the   workplace.  These
"Right-to-Know" laws usually require employers  to list all hazardous  chemicals
in  the workplace, to instruct  workers about safe work  practices, and to train
workers on how to respond in the case of exposure to or release of the hazardous
chemical. OSHA's Hazard Communication Standard requires all employers to provide
information and training regarding hazardous chemicals in the workplace.

    Most states and local governments  have adopted licensing and  certification
requirements  for workers engaged  in the environmental  industry, which require
workers to attend training classes. ATC is currently accredited by the  National
Voluntary  Laboratory  Program and  expects to  continue  to participate  in all
future National Institute of Standards and Technology programs. In addition, ATC
maintains various licenses and certifications pertaining to its laboratories and
certain  field  testing  equipment.  ATC  has  not  experienced,  and  does  not
contemplate,   any  material  difficulties  in  complying  with  regulatory  and
licensing provisions applicable to its business. ATC has received citations from
governmental authorities, none of  which have had a  material adverse effect  on
the Company's business operations.

INSURANCE

    ATC  has secured  a "claims  made" professional  liability insurance policy,
including contractor's pollution liability coverage, for claims with a limit  of
$2,000,000  and a  deductible of $150,000,  although increased  limits have been
obtained on a specific endorsement basis to meet the needs of particular clients
or contracts. A "claims  made" policy only insures  against claims filed  during
the  period in which the policy is in effect. This policy covers both errors and
omissions. ATC's policy has been renewed in each of the last several years  that
the  policy has been in  effect. The relatively low  dollar amount of the policy
limit currently offered, the possible  future unavailability or modification  of
this  insurance  or any  significant increase  in insurance  rates could  have a
materially adverse effect  on ATC's operations.  Further, because customers  may
require   that   ATC   maintain  liability   insurance,   the   possible  future
unavailability of such insurance could adversely affect ATC's ability to compete
effectively.

    ATC has in the  past filed two  notices of claims  which, in the  aggregate,
amounted  to $5,540,000 in  amount claimed. Although both  of these matters were
dismissed in  the Company's  favor, in  each  case without  the payment  of  any
damages, no assurances can be given that future claims will not be filed against
the  Company or that  the Company will  continue to be  able to obtain insurance
coverage on terms satisfactory to the Company.

PERSONNEL

   
    As of August 1,  1995, ATC employed 641  employees, including 497  full-time
employees.  The Company's  employees consist  of 475  technical and professional
personnel, 24  sales  and marketing  persons  and 142  administrative  employees
inclusive  of  executive  officers.  The  backgrounds  of  ATC's  technical  and
professional staff include, among other disciplines, environmental  engineering,
industrial  hygiene and hydrogeology,  chemistry, biology and  geology. ATC from
time to time hires additional personnel on a temporary basis.
    

    ATC believes that it has been able  to establish and maintain a stable  work
force  of experienced  personnel by  paying competitive  wages and  by providing
standard benefits. ATC also  pays the costs  as they arise  to have its  workers
certified  for its asbestos and environmental requirements, including tuition at
a certified training program and fees for certification, testing and  licensing.
ATC  believes that its own training school has helped to ensure the availability
of a trained work force.

                                       29

FACILITIES

    ATC leases office space, laboratory facilities, temporary housing facilities
and storage space under 36 operating  lease agreements, which expire at  varying
dates.  Although ATC's  utilization of these  leased facilities  is near maximum
capacity at  all locations,  there is  no  location at  which ATC  foresees  any
material difficulty in leasing adequate supplementary sites, if necessary, under
terms similar to those enjoyed under current leases.

    In  its  business,  ATC  utilizes  various  laboratory,  field  and computer
equipment  which  are  owned   or  leased.  ATC  also   rents  equipment  on   a
project-by-project basis.

                               LEGAL PROCEEDINGS

    ATC  is not presently a  party to any material  litigation; nor are any such
proceedings pending or threatened.

exercise of warrants. The exercise price of the Class C Warrants and the  number
of  shares  issuable  upon exercise  of  the  Class C  Warrants  are  subject to
anti-dilution adjustment  to  protect  against stock  dividends,  stock  splits,
mergers  and  recapitalizations. In  accordance with  the terms  of the  Class C
Warrants, ATC is required  to maintain a current  and effective registration  of
the securities issuable upon exercise of the Class C Warrants.

DELAWARE LAW

    Section   203  of   the  Delaware   General  Corporation   Law  prohibits  a
publicly-held Delaware corporation from engaging in "business combination"  with
an  "interested stockholder" for a  period of three years  after the date of the
transaction in which  the person  became an interested  stockholder, unless  the
business   combination  is  approved   in  a  prescribed   manner.  A  "business
combination" includes mergers, asset sales and other transactions resulting in a
financial benefit to the  stockholder. An "interested  stockholder" is a  person
who,  together with affiliates and associates,  owns (or within three years, did
own) 15% or more of the corporation's voting stock.

INDEMNIFICATION

    As permitted by the Delaware  General Corporation Law, ATC's Certificate  of
Incorporation  provides that a director of ATC  will not be personally liable to
ATC or its Stockholders for monetary damages for breach of the fiduciary duty of
care as a director, except under  certain circumstances including breach of  the
director's  duty of loyalty to  ATC or its Stockholders  or any transaction from
which the director derived an improper personal benefit.

    ATC's  By-Laws  provide  for  the  indemnification  of  ATC's  officers  and
directors  to the fullest extent permitted by Delaware law. In this respect, ATC
entered into indemnification agreements with its officers and directors to  hold
them  harmless and to indemnify each person  from and against all fines, amounts
paid in settlements and expenses, including attorneys' fees incurred as a result
of or in connection  with any threatened, pending  or completed action, suit  or
proceeding,  whether  civil,  criminal or  administrative  or  investigative, by
reason of the fact that  the person was a director  or officer of ATC or  served
any  other corporation in any capacity at the  request of ATC, in the manner and
to the extent permitted by law.

    ATC has been advised that it is  the opinion of the Commission that  insofar
as  the foregoing  provisions may be  invoked to disclaim  liability for damages
arising under  the federal  securities laws,  that such  provisions are  against
public   policy  as  expressed  in  such   securities  laws  and  are  therefore
unenforceable.

TRANSFER AGENT AND EXCHANGE AGENT

    American Stock Transfer &  Trust Company, New York,  New York, is acting  as
transfer agent and warrant agent for ATC's securities.

    The Underwriting  Agreement provides  that the  obligations of  the  several
Underwriters  thereunder are  subject to  approval of  certain legal  matters by
counsel and to  various other  considerations. The nature  of the  Underwriters'
obligations  is such that the Underwriters are committed to purchase and pay for
all of the above shares of Common Stock if any are purchased.

    The Underwriters, through the Representatives, have advised the Company that
they propose to offer  the Common Stock initially  at the public offering  price
set  forth on the cover page of this Prospectus, that the Underwriters may allow
to selected dealers a concession of $       per share, and that such dealers may
reallow a concession of $        per  share to certain other dealers. After  the
public  offering, the offering price  and other selling terms  may be changed by
the Underwriters.  The Common  Stock is  included for  quotation on  the  Nasdaq
National Market.

    The  Company has granted to the  Underwriters a 30-day over-allotment option
to purchase up  to an aggregate  of 360,000 additional  shares of Common  Stock,
exercisable  at the public offering price less the underwriting discount. If the
Underwriters exercise such over-allotment option, then each of the  Underwriters
will  have  a  firm  commitment,  subject  to  certain  conditions,  to purchase
approximately the same  percentage thereof  as the  number of  shares of  Common
Stock to be purchased by it, as shown in the above table, bears to the 2,400,000
shares of Common Stock offered hereby. The Underwriters may exercise such option
only  to cover over-allotments made in connection with the sale of the shares of
Common Stock offered hereby.

    The Underwriting  Agreement  provides  that  for a  period  of  three  years
following  the consummation of this offering, Rodman  has the right to appoint a
member to  the Company's  Board of  Directors. Rodman  has designated  Julia  S.
Heckman  as its  initial designee  to the  Board of  Directors. The  Company has
agreed to indemnify Rodman's designee to the fullest extent permitted by law.

   
    The officers and directors of the Company and the Selling Stockholders  have
agreed  that they will not sell or dispose  of any shares of Common Stock of the
Company for a  period of  180 days  after the  later of  the date  on which  the
Registration Statement is declared effective by the Commission or the first date
on  which the  shares are  bona fide  offered to  the public,  without the prior
written consent of the Representatives.
    

    The Company  has  agreed  to  indemnify  the  Underwriters  against  certain
liabilities, losses and expenses, including liabilities under the Securities Act
of  1933, as amended (the  "Securities Act"), or to  contribute to payments that
the Underwriters may be required to make in respect thereof.

                                       35

    In connection  with  the  offering made  hereby,  certain  Underwriters  and
selling  group members (if any) or their respective affiliates who are qualified
registered market makers  on the Nasdaq  National Market may  engage in  passive
market  making transactions in the Common Stock on the Nasdaq National Market in
accordance with Rule 10b-6A under the Exchange Act, during the two business  day
period  before commencement of offers or sales  of the Common Stock. The passive
market making transactions must comply  with applicable volume and price  limits
and  be identified as such.  In general, a passive  market maker may display its
bid at a price not in excess  of the highest independent bid for such  security;
if  all  independent bids  are  lowered below  the  passive market  maker's bid,
however, such  bid  must  then  be lowered  when  certain  purchase  limits  are
exceeded.

                                 LEGAL MATTERS

    The  validity of the issuance of the  shares of Common Stock offered by this
Prospectus will be passed upon for the Company by Lester Morse P.C., Great Neck,

                  PRO FORMA UNAUDITED COMBINED FINANCIAL DATA

    The following Pro Forma Unaudited Combined Financial Data for ATC and Aurora
have been prepared based upon the historical financial results of the companies,
adjusted  to give effect to  the Aurora Merger and  the Company's acquisition of
Con-Test. The Pro  Forma Combined Unaudited  Financial Data give  effect to  the
merger  of ATC and Aurora  under a method of accounting  similar to a pooling of
interests and the acquisition of Con-Test  by ATC, under the purchase method  of
accounting,  based upon the assumptions set forth  in the notes to the pro forma
unaudited combined financial data.

    The pro forma  combined statements of  operations for the  six months  ended
August  31, 1995 and for the year ended February 28, 1995, reflect the merger of
ATC and Aurora and the  acquisition of Con-Test as if  each had occurred at  the
beginning of the period presented.

    The   Pro  Forma  Unaudited  Combined  Financial  Data  should  be  read  in
conjunction with the audited and unaudited consolidated financial statements  of
the Company, Aurora and Con-Test appearing elsewhere in this Prospectus.

    The  pro forma combined  results are intended  for information purposes only
and are not necessarily indicative of the results which would have been attained
if the  merger and  acquisition had  been consummated  at the  beginning of  the
period presented or which may be attained in the future.

NOTE 1 -- GENERAL

MERGER OF AURORA INTO ATC

    Effective  June  29, 1995,  ATC  and Aurora  were  merged, with  ATC  as the
surviving corporation. Prior to the Aurora Merger, Aurora was a holding  company
which  owned  approximately  57%  of  ATC's  outstanding  Common  Stock  and had
substantially no other assets. In  connection with the merger, each  outstanding
share  of Aurora common stock was exchanged for .545 shares of Common Stock. ATC
issued 3,341,452 shares  of Common  Stock in  exchange for  6,131,104 shares  of
Aurora's  common stock,  and issued options  and warrants  entitling the holders
thereof to  purchase up  to 604,950  shares  of Common  Stock upon  exercise  in
replacement  of previously outstanding options and warrants to purchase Aurora's
common stock. The merger was accounted for  in a manner similar to a pooling  of
interests.  Under this method of accounting,  recorded assets and liabilities of
Aurora are combined with ATC and the results of operations of ATC and Aurora are
combined as of the effective date of the merger.

ACQUISITION OF ASSETS OF CON-TEST

    Effective October 1, 1994, ATC purchased certain assets and assumed  certain
liabilities  of  Con-Test,  a Massachusetts-based  environmental  consulting and
engineering company with branch offices in Massachusetts, Connecticut,  Vermont,
Rhode  Island, New York and Pennsylvania. The acquisition was accounted for as a
purchase.  The  total  consideration  for  this  acquisition  was  approximately
$7,760,000,  consisting of $2,100,000 in cash, restricted shares of Common Stock
valued at  $493,000, $535,000  in a  three-year promissory  note, $4,500,000  of
assumed   liabilities  and  $132,000  of  acquisition  costs.  Certain  of  this
consideration is contingent upon collection of outstanding receivables  acquired
by  ATC.  Immediately  upon  acquiring  the  assets  of  Con-Test,  the  Company
instituted several cost-saving  measures, including the  elimination of  certain
employees and facilities, to improve Con-Test's operations and integrate it with
the existing operations of the Company.

    The  pro  forma combined  balance sheet  sets forth  the combination  of the
financial positions of ATC and Aurora as of May 31, 1995.

    The pro forma combined statements of  operations for the three months  ended
May 31, 1995 and for the year ended February 28, 1995, reflect the merger of ATC
and  Aurora  and the  acquisition of  Con-Test as  if each  had occurred  at the
beginning of the period presented.

Stockholders and Board of Directors
ATC Environmental Inc. and Subsidiaries

    We  have  audited  the  accompanying  consolidated  balance  sheets  of  ATC
Environmental Inc. and subsidiaries  as of February 28,  1995 and 1994, and  the
related  consolidated statements  of operations,  stockholders' equity  and cash
flows for each of the three years  in the period ended February 28, 1995.  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, such  consolidated financial statements  present fairly, in
all material  respects, the  financial position  of ATC  Environmental Inc.  and
subsidiaries  as  of  February  28,  1995 and  1994  and  the  results  of their
operations and their cash flows for each of the three years in the period  ended

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  YEARS ENDED FEBRUARY 28, 1993, 1994 AND 1995

NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

    The   consolidated  financial   statements  include  the   accounts  of  ATC
Environmental Inc. and its wholly-owned subsidiaries ATC New England Corp.,  ATC
Blattert Inc., Hygeia Proscience Laboratories, Inc. and ATC Management, Inc. All
significant intercompany accounts and transactions have been eliminated.

NATURE OF BUSINESS

    ATC  Environmental Inc.  and its subsidiaries  ("ATC" or  the "Company") are
environmental  consulting  firms  providing  assessment,  monitoring,  training,
analytical  and management  services for environmental  projects. These services
are provided nation-wide  through a network  of regional offices.  ATC is a  57%
owned  subsidiary of Aurora  Environmental Inc. ("Aurora").  Because the Company
conducts its  operations  in  a  single industry,  segment  information  is  not
presented.

REVENUE RECOGNITION

    The  Company generally contracts for services to customers on the basis of a
fixed fee per procedure or services performed. Revenue is recognized as services
are performed in accordance with the terms of the contract.

COSTS IN EXCESS OF BILLINGS ON UNCOMPLETED CONTRACTS

    Costs in  excess of  billings on  uncompleted contracts  represent  unbilled
services and reimbursable expenses associated with ongoing projects

SIGNIFICANT CUSTOMER

    In  fiscal 1995, revenues from a single customer comprised approximately 11%
of total  revenues.  In  fiscal  1994  revenues  from  this  customer  comprised
approximately 12% of total revenues.

PROPERTY AND EQUIPMENT

    Property  and equipment  are carried  at cost.  Depreciation is  computed on
either the straight-line or declining  balance method over the estimated  useful
lives of the assets, as follows:

<TABLE>
<S>                                                                 <C>
Office equipment..................................................         5 years
Transportation equipment..........................................       4-5 years
Laboratory and field equipment....................................       5-7 years
                                                                       life of the
Leasehold improvements............................................           lease
</TABLE>

AMORTIZATION OF INTANGIBLE ASSETS

    Goodwill  associated with acquisitions is being amortized on a straight-line
basis over  a  10  to  30  year  period.  The  carrying  value  of  goodwill  is
periodically  evaluated  on  the  basis  of  management's  estimates  of  future
undiscounted operating income  associated with the  acquired business. When  the
carrying  amount of goodwill is determined  not to be recoverable by management,
the associated asset is  written off. At February  28, 1995, no such  impairment
existed.  The covenants not to compete are being amortized over the terms of the
agreements, which are 3 to 5 year periods.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                  YEARS ENDED FEBRUARY 28, 1993, 1994 AND 1995

NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INCOME TAXES

    The liability method is used to measure deferred tax assets and  liabilities
in  accordance  with  Statement  of  Financial  Accounting  Standards  No.  109,
ACCOUNTING FOR INCOME  TAXES, based on  temporary differences between  financial
and  taxable income existing at each balance sheet date using enacted tax rates.
ATC and its wholly-owned subsidiaries file a consolidated income tax return.

CONTINUING REGISTRATION COSTS

    Costs associated with the  registration and issuance  of equity are  charged
against  additional paid-in capital  as incurred. These  costs generally include
legal  and  accounting  fees,  printing  costs  and  other  direct  expenses  of
registration statement filings.

CREDIT RISK AND FINANCIAL INSTRUMENTS

    Financial   instruments   which   potentially   subject   the   Company   to
concentrations of  credit risk  are primarily  cash, temporary  investments  and
accounts  receivable.  The Company  places its  temporary investments  in highly
rated financial institutions and  investment grade short-term debt  instruments.
Concentrations  of credit risk  with respect to  accounts receivable are limited
due to  the  large number  of  customers,  the proportion  of  receivables  from
governmental  entities,  generally  short payment  terms  and  dispersion across
geographic areas.

EARNINGS PER COMMON SHARE AND DILUTIVE COMMON EQUIVALENT SHARE

    Earnings per common  share and  dilutive common equivalent  share have  been
computed  by using the weighted average  number of shares outstanding during the
year. Outstanding dilutive stock warrants and stock options are included in  the
computation of weighted average number of shares.

CASH AND CASH EQUIVALENTS

    For  purposes of reporting cash flows,  the Company considers all commercial
paper, money market funds and certificates of deposit purchased with a  maturity

BIO/WEST, INC.

    On June 10, 1992, ATC signed a purchase agreement for 100% of the issued and
outstanding  common  stock  of  Bio/West, Inc.  ("Bio/West"),  a  privately held
environmental  consulting  firm   specializing  in   ecological  services.   The
acquisition was accounted for as a purchase.

    On  October 14, 1993, because of  certain disputes which arose subsequent to
the purchase, the Company and the  former stockholders of Bio/West entered  into
an agreement for restitution following rescission, which provided for an orderly
rescission  of the  purchase. The  agreement effected  a refund  of the purchase
price by the  former Bio/West stockholders  to ATC  and a return  to the  former
stockholders  of all ownership and stock  of Bio/West. Under this agreement, the
former stockholders of Bio/West  refunded the cash payment  to ATC, forgave  the
notes  payable, forgave all amounts payable  under the profit contingent portion
of the original purchase agreement and  reimbursed ATC for expenses incurred  by
it  on behalf of Bio/West.  In order to provide  sufficient funds for the former
shareholders of Bio/West to  make full restitution  provided in the  rescission,
ATC  loaned these  former stockholders  $375,000 supported  by promissory notes.
These notes were paid in full as of  February 28, 1995. ATC also entered into  a
separate  non-compete agreement  with Bio/West requiring  ATC to pay  a total of
$137,000 to Bio/West over three years.

    The accompanying consolidated statements of operations reflect the  revenues
and  expenses  of the  Company and  its subsidiaries,  including the  results of
Bio/West's  operations  through  May  31,  1993,  the  effective  date  of   the
rescission.  The results of operations of  Bio/West included in the consolidated
financial statements were  revenues of  $2,924,290 and $468,731  and net  income
(loss) of $29,657 and $(109,846) in fiscal 1993 and 1994, respectively.

prices which cannot be less than the fair market value at the time of the grant.
Options  become exercisable  20% per year  for certain participants  and 50% per
year for other participants and expire within five years of the date of grant.

    Additionally, in January 1988, the Company granted options for the  purchase
of  342,000 shares  of common  stock at  a price  of $.15  per share  in part to
related parties. The Company determined that the option price approximated  fair
market value at the date of grant and, accordingly, no compensation was recorded
pursuant  to these options. These options have all been exercised as of February
28, 1993.

    On July 16, 1993, the Board of Directors approved an additional stock option
plan providing for the granting of 200,000 options to employees for purchase  of
common  stock at prices which cannot be less  than fair market value at the time

NOTE L -- SUBSEQUENT EVENT -- MERGER AGREEMENT (UNAUDITED)

    ATC and Aurora have entered into an  agreement to merge, with ATC to be  the
surviving  corporation. The agreement is subject to certain conditions including
the approval of  both ATC's and  Aurora's stockholders. Approval  of the  merger
will  require a majority  vote of each  of the corporations.  Under the proposed
agreement, ATC would exchange  .545 of a  share of ATC stock  for each share  of
Aurora  stock. ATC common shares held by Aurora, 3,258,000 at February 28, 1995,
would be cancelled. The merger would be  accounted for in a manner similar to  a
pooling  of  interests. Under  this method  of  accounting, recorded  assets and
liabilities of Aurora would be combined  with ATC and the results of  operations
of  ATC  and  Aurora  would also  be  combined  on the  date  the  merger became
effective. After the merger, ATC would be able to utilize Aurora's net operating
loss carryforward, which is  $970,000 at February 28,  1995. In addition,  ATC's
liability to Aurora would be cancelled at the merger date.

ATC ENVIRONMENTAL INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

NOTE A -- GENERAL

PRINCIPLES OF CONSOLIDATION

    The   consolidated  financial   statements  include  the   accounts  of  ATC
Environmental Inc. and its wholly-owned subsidiaries ("ATC" or the "Company").

    In the  opinion  of the  Company,  the accompanying  unaudited  consolidated
financial   statements  contain  all  adjustments  (consisting  only  of  normal
recurring accruals) necessary to present  fairly, in all material respects,  the
financial  position as of August 31, 1995, and the results of operations and the
cash flows for  the periods ended  August 31,  1994 and 1995.  These results  of
operations  are not necessarily indicative of the results to be expected for the
full year due to certain seasonality factors and the effects and timing of large
service projects.

   
    Certain information and footnote disclosures normally included in  financial
statements  prepared in accordance with generally accepted accounting principles
have been  omitted.  These condensed  financial  statements should  be  read  in
conjunction with the consolidated financial statements and the notes included in
the  Company's financial statements for the fiscal year ended February 28, 1995,
which are included elsewhere in this Prospectus.
    

NATURE OF BUSINESS

    ATC is a  national environmental consulting  and engineering firm  providing
assessment,   monitoring,  training,  analytical  and  management  services  for
environmental projects.  These  services  are  provided  nation-wide  through  a
network  of regional offices.  Because the Company conducts  its operations in a
single industry, segment information is not presented.

SIGNIFICANT CUSTOMERS

    Revenues from two customers comprised  approximately 9.7% of total  revenues
during  the six months  ended August 31, 1995  as compared to  25.0% for the six
months ended August 31, 1994.

CREDIT FACILITIES

    During the quarter ended  August 31, 1995, the  Company extended its  credit
facilities  with Atlantic Bank of New York by a total of $500,000. At August 31,
1995, the Company had borrowed the additional $500,000, which is due October 31,
1995.

STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 121

    On March  1, 1996,  the  Company intends  to  adopt Statement  of  Financial
Accounting  Standards  ("SFAS")  No.  121,  "Accounting  for  the  Impairment of
Long-Lived Assets to be Disposed  Of." Management anticipates that the  adoption
of  SFAS No.  121 will  not have  a material  effect on  the Company's financial
statements.

EARNINGS PER SHARE DATA

    Earnings per common  share and  dilutive common equivalent  share have  been
computed  by using the weighted average number of shares outstanding during each
period. Outstanding  dilutive stock  warrants and  options are  included in  the
computation of weighted average number of shares.

RECLASSIFICATIONS

    Certain  reclassifications have  been made  to the  prior period's financial
statements to conform to the current years presentation.

NOTE B -- BUSINESS ACQUISITIONS

    The following  acquisitions  have  been  accounted  for  as  purchases.  The
acquired  company's  assets and  liabilities  are included  in  the accompanying
consolidated balance sheet at fair value  at the date of purchase. The  acquired
company's  operations subsequent to acquisition are included in the accompanying
consolidated statement of operations.

CON-TEST, INC.

    On October  1,  1994, ATC  acquired  substantially  all of  the  assets  and
liabilities  of Con-Test, Inc. ("Con-Test"), a Massachusetts based environmental
consulting and  engineering company  having branch  offices in  the New  England
states, New York and Pennsylvania. The seller has guaranteed the net receivables
purchased.

    On  September  28, 1995,  the Company  served  the seller  with a  notice of
set-off pursuant to the purchase agreement. Under this set-off, ATC is  entitled
to recover shares of its Common Stock originally issued to the seller, valued at
the  closing price  of the  stock at  the date  of the  claim, equal  to the net
uncollected  receivables  acquired   in  the  purchase.   The  net   uncollected
receivables  were approximately $460,000 and  accordingly the Company expects to
recover approximately 32,000 shares of its Common Stock previously issued in the
acquisition.

    The effect of this transaction on the  financial position of ATC will be  to
reduce  the recorded net accounts receivable, reduce Common Stock and additional
paid in capital and to increase  goodwill. This transaction will be recorded  in
the Company's third quarter.

R.E. BLATTERT & ASSOCIATES

    On  January  13, 1995,  ATC  acquired substantially  all  of the  assets and
liabilities  of  R.E.  Blattert  &  Associates  ("Blattert"),  an  environmental
consulting  firm having  geologic, environmental engineering  and water resource
expertise with offices in  Indiana and Iowa. The  seller has guaranteed the  net
receivables  purchased.  In addition,  the purchase  agreement provides  for the
seller to receive additional purchase consideration up to a maximum of  $850,000
over  a four-year period based on  achieving agreed upon earnings targets. These
contingent payments  will be  recorded as  goodwill if  subsequently earned.  At
August 31, 1995, no additional purchase consideration had been earned.

MICROBIAL ENVIRONMENTAL SERVICES, INC.

    On   January  4,  1995,   ATC  acquired  certain   operations  of  Microbial
Environmental Services, Inc. ("MES"). ATC  agreed to assume service  performance
obligations   under  certain  contracts  and  a  lease  obligation  of  MES.  In
consideration,  MES  assigned  accounts  receivable  to  ATC.  ATC  additionally
purchased  certain field and  laboratory equipment from MES  and paid a finder's
fee to an unrelated party.

NOTE D -- MERGER OF ATC AND AURORA

    ATC and  its  parent,  Aurora  Environmental  Inc.  ("Aurora")  were  merged
pursuant  to an  agreement (the  "Merger Agreement")  approved by  a majority of
shareholders of each  company on  June 29, 1995,  with ATC  being the  surviving
corporation.  Under the Merger Agreement,  ATC exchanged .545 of  a share of ATC
Common Stock for each of Aurora's  6,131,104 shares of stock outstanding.  ATC's
common  shares held by Aurora of  3,258,000 were cancelled. Actual common shares
outstanding increased by 83,452  shares and the  fully diluted weighted  average
shares outstanding increased by 408,566 and 204,283 for the three and six months
ended  August 31,  1995, respectively, representing  the dilutive  effect of the
converted Aurora shares, options and warrants. The merger has been accounted for
in a manner similar to a pooling of interests. Under this method of  accounting,
recorded  assets and liabilities of  Aurora were combined with  those of ATC and
the results of operations of  ATC and Aurora were  combined as of the  effective
date of the merger. In addition, the intercompany balance between ATC and Aurora
was forgiven.

NOTE E -- UTILIZATION OF AURORA NET OPERATING LOSS CARRYFORWARD
    As  a  result  of the  merger,  ATC will  be  able to  utilize  Aurora's net
operating loss carryforward, which  resulted in a  one-time reduction of  income
tax expense of approximately $350,000 ($0.05 per share) that is reflected in the
second quarter's operating results.

NOTE G -- SUBSEQUENT EVENT -- COMMON STOCK OFFERING
    On  September 8, 1995,  the Company filed a  Registration Statement with the
Securities and Exchange Commission  for the sale of  2,400,000 shares of  Common
Stock  of which 1,700,000 are to  be sold by ATC, while  the remaining are to be
sold by an officer/director of ATC.

    The Company plans to utilize a portion  of the net proceeds of the  proposed
public  offering to repay  the debt outstanding under  its credit facilities. At
September 30, 1995, $5,500,000 was outstanding under these credit facilities. It
is anticipated that a substantial portion  of the remaining net proceeds of  the
offering  will be utilized to expand  the Company's operations through strategic
acquisitions of companies with complementary services, products or technologies,
as well as  through internal  expansion. In addition,  the net  proceeds of  the
offering will be available for general working capital purposes.

    We  have  audited the  accompanying  consolidated balance  sheets  of Aurora
Environmental Inc. and  subsidiary as  of February 28,  1995 and  1994, and  the
related  consolidated statements  of operations,  stockholders' equity  and cash

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, such  consolidated financial statements  present fairly, in
all material respects, the financial  position of Aurora Environmental Inc.  and

                    AURORA ENVIRONMENTAL INC. AND SUBSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

    The  consolidated  financial  statements  include  the  accounts  of  Aurora
Environmental  Inc.   ("Aurora")   and   its   majority-owned   subsidiary   ATC
Environmental  Inc. ("ATC" or the "Company"). ATC's financial statements include
the accounts  of  its  wholly-owned  subsidiaries ATC  New  England  Corp.,  ATC
Blattert Inc., Hygeia Proscience Laboratories, Inc. and ATC Management, Inc. All
significant intercompany accounts and transactions have been eliminated.

NATURE OF BUSINESS

    Aurora  operates solely as  a holding company for  ATC. Substantially all of
the assets, liabilities and results of operations reflected in the  accompanying
financial  statements are those of ATC. ATC is a 57% owned subsidiary of Aurora.
ATC is  an  environmental  consulting  firm  providing  assessment,  monitoring,
training,  analytical and management services  for environmental projects. These
services are provided nation-wide through a network of regional offices. Because
the Company conducts its operations in a single industry, segment information is
not presented.

REVENUE RECOGNITION

    The Company generally contracts for services to customers on the basis of  a
fixed fee per procedure or services performed. Revenue is recognized as services
are performed in accordance with the terms of the contract.

COSTS IN EXCESS OF BILLINGS ON UNCOMPLETED CONTRACTS

    Costs  in  excess of  billings on  uncompleted contracts  represent unbilled
services and reimbursable expenses associated with ongoing projects.

SIGNIFICANT CUSTOMER

    In fiscal 1995, revenues from a single customer comprised approximately  11%
of  total  revenues.  In  fiscal 1994,  revenues  from  this  customer comprised
approximately 12% of total revenues.

PROPERTY AND EQUIPMENT

    Property and  equipment are  carried at  cost. Depreciation  is computed  on
either  the straight-line or declining balance  method over the estimated useful
lives of the assets, as follows:

Office Equipment..................................................         5 years
Transportation equipment..........................................       4-5 years
Laboratory and field equipment....................................       5-7 years
                                                                       life of the
Leasehold improvements............................................           lease
</TABLE>

AMORTIZATION OF INTANGIBLE ASSETS

    Goodwill associated with acquisitions is being amortized on a  straight-line
basis  over  a  10  to  30  year  period.  The  carrying  value  of  goodwill is
periodically  evaluated  on  the  basis  of  management's  estimates  of  future
undiscounted  operating income associated  with the acquired  business. When the
carrying amount of goodwill is determined  not to be recoverable by  management,
the  associated asset is written  off. At February 28,  1995, no such impairment
existed. The covenants not to compete are being amortized over the terms of  the
agreements, which are 3 to 5 year periods.

                    AURORA ENVIRONMENTAL INC. AND SUBSIDIARY
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INCOME TAXES

    The  liability method is used to measure deferred tax assets and liabilities
in  accordance  with  Statement  of  Financial  Accounting  Standards  No.  109,
ACCOUNTING  FOR INCOME TAXES,  based on temporary  differences between financial
and taxable income existing at each balance sheet date using enacted tax  rates.
Aurora  files  a separate  income  tax return;  while  ATC and  its wholly-owned
subsidiaries file a consolidated income tax return.

CONTINUING REGISTRATION COSTS

    Costs associated with the  registration and issuance  of equity are  charged
against  additional paid-in capital  as incurred. These  costs generally include
legal  and  accounting  fees,  printing  costs  and  other  direct  expenses  of
registration statement filings.

CREDIT RISK AND FINANCIAL INSTRUMENTS

    Financial   instruments   which   potentially   subject   the   Company   to
concentrations of  credit risk  are primarily  cash, temporary  investments  and
accounts  receivable.  The Company  places its  temporary investments  in highly
rated financial institutions and  investment grade short-term debt  instruments.
Concentrations  of credit risk  with respect to  accounts receivable are limited
due to  the  large number  of  customers,  the proportion  of  receivables  from
governmental  entities,  generally  short payment  terms  and  dispersion across
geographic areas.

EARNINGS PER COMMON SHARE AND DILUTIVE COMMON EQUIVALENT SHARE

    Earnings per common  share and  dilutive common equivalent  share have  been
computed  by using the weighted average  number of shares outstanding during the
year. Outstanding dilutive stock warrants and stock options are included in  the
computation of weighted average number of shares.

CASH AND CASH EQUIVALENTS

    For  purposes of reporting cash flows,  the Company considers all commercial
paper, money market funds and certificates of deposit purchased with a  maturity
of three months or less at acquisition to be cash equivalents.

RECLASSIFICATIONS

    Certain  reclassifications  have been  made  to the  prior  years' financial
statements to conform to the current year's presentation.

BIO/WEST, INC.

    On June 10, 1992, ATC signed a purchase agreement for 100% of the issued and
outstanding  common  stock  of  Bio/West, Inc.  ("Bio/West"),  a  privately held
environmental  consulting  firm   specializing  in   ecological  services.   The
acquisition was accounted for as a purchase.

    On  October 14, 1993, because of  certain disputes which arose subsequent to
the purchase, the Company and the  former stockholders of Bio/West entered  into
an agreement for restitution following rescission, which provided for an orderly
rescission  of the  purchase. The  agreement effected  a refund  of the purchase
price by the  former Bio/West stockholders  to ATC  and a return  to the  former
stockholders  of all ownership and stock  of Bio/West. Under this agreement, the
former stockholders of Bio/West  refunded the cash payment  to ATC, forgave  the
notes  payable, forgave all amounts payable  under the profit contingent portion
of the original purchase agreement and  reimbursed ATC for expenses incurred  by
it  on behalf of Bio/West.  In order to provide  sufficient funds for the former
shareholders of Bio/West to make full restitution provided in the recission, ATC
loaned these former stockholders $375,000  supported by promissory notes.  These
notes  were  paid in  full as  of February  28,  1995. ATC  also entered  into a
separate non-compete agreement  with Bio/West requiring  ATC to pay  a total  of
$137,000 to Bio/West over three years.

    The  accompanying consolidated statements of operations reflect the revenues
and expenses  of the  Company and  its subsidiaries,  including the  results  of
Bio/West's   operations  through  May  31,  1993,  the  effective  date  of  the
rescission. The results of operations  of Bio/West included in the  consolidated
financial  statements were  revenues of $2,924,290  and $468,731  and net income
(loss) of $29,657 and $(109,846) in fiscal 1993 and 1994, respectively.

    A  stock option  plan, approved by  the Board  of Directors of  ATC in 1988,
provides for the granting of 200,000 options to employees for purchase of common
stock at prices which cannot be less than  the fair market value at the time  of
the  grant. Options become exercisable 20% per year for certain participants and
50% per year for other participants and expire within five years of the date  of
the grant.

    Additionally,  in  January 1988,  ATC granted  options  for the  purchase of
342,000 shares of common stock at a price  of $.15 per share in part to  related
parties.  ATC determined that the option price approximated fair market value at
the date of  grant and, accordingly,  no compensation was  recorded pursuant  to
these options. These options have all been exercised as of February 28, 1993.

    On July 16, 1993, the Board of Directors of ATC approved an additional stock
option  plan  providing for  the granting  of 200,000  options to  employees for
purchase of common stock at prices which  cannot be less than fair market  value
at  the time of grant. Options become exercisable 20% per year and expire within
five years of the date of grant.

    At February 28, 1995, ATC had granted options under the 1988 and 1993  plans
for  291,400 shares, of which  options for 19,980 shares  had been exercised and
options for 127,000 shares were  exercisable. Additionally, in fiscal 1995,  the
Board  of  Directors approved  the granting  of 20,000  options to  an unrelated
consultant for purchase of common stock at $9.50 per share (fair market value at
date of grant). The option shares are subject to changes in capitalization.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE H -- INCOME TAXES (CONTINUED)
    The current portion of net deferred  tax assets of $152,600 and $132,700  at
February  28, 1994 and 1995  is classified in the  consolidated balance sheet in
current assets. The noncurrent portion is classified in noncurrent liabilities.

    Aurora and  ATC file  separate income  tax returns.  At February  28,  1995,
Aurora  has net  operating loss  (NOL) carryforwards  of approximately $970,000,
which expire through 2010. The  valuation allowance provided for deferred  taxes
relates entirely to the Aurora NOL. This valuation allowance will be recorded as
a  reduction of income  tax expense in  future periods if  realization of future
deductions becomes more likely than not.

    During fiscal 1993, ATC recorded  in additional paid-in capital $344,000  of
tax  benefit  from the  exercise of  common stock  warrants and  options. During
fiscal 1994, ATC adjusted its tax benefit recorded in additional paid-in capital
downward by $40,927 to reflect the  actual tax benefit realized. Aurora's  share
of  these transactions  is recorded within  stockholders' equity as  part of the
adjustments resulting from capital transactions of its subsidiary.

NOTE I -- EMPLOYEE BENEFIT PLANS
    The Company  has  an  employee  savings  plan  which  allows  for  voluntary
contributions  into  designated  investment  funds  by  eligible  employees. The
Company may,  at the  discretion  of its  Board  of Directors,  make  additional
contributions  on behalf  of the  Plan's participants.  No Company contributions
were made in fiscal years 1993, 1994 and 1995.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE K -- SUBSEQUENT EVENT -- MERGER AGREEMENT (UNAUDITED)
    ATC and Aurora have entered into an  agreement to merge, with ATC to be  the
surviving  corporation. The agreement is subject to certain conditions including
the approval of  both ATC's and  Aurora's stockholders. Approval  of the  merger
will  require a majority  vote of each  of the corporations.  Under the proposed
agreement, ATC would exchange  .545 of a  share of ATC stock  for each share  of
Aurora  stock. ATC common shares held by Aurora, 3,258,000 at February 28, 1995,
would be cancelled. The merger would be  accounted for in a manner similar to  a
pooling  of  interests. Under  this method  of  accounting, recorded  assets and
liabilities of Aurora would be combined  with ATC and the results of  operations
of  ATC  and  Aurora  would also  be  combined  on the  date  the  merger became
effective. After the merger, ATC would be able to utilize Aurora's net operating
loss carryforward, which is  $970,000 at February 28,  1995. In addition,  ATC's
liability to Aurora would be cancelled at the merger date.

PRO FORMA FINANCIAL INFORMATION (UNAUDITED)

    The  following unaudited  pro forma  information sets  forth the  results of
operations of ATC and Aurora as if the merger and ATC's acquisitions of BSE  and
Con-Test and rescission of Bio/West had occurred on March 1, 1993:

                    AURORA ENVIRONMENTAL INC. AND SUBSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

NOTE A -- GENERAL

PRINCIPLES OF CONSOLIDATION

    The  consolidated  financial  statements  include  the  accounts  of  Aurora
Environmental Inc.
("Aurora" or the "Company") and its subsidiary, ATC Environmental Inc.  ("ATC").
ATC is a 57% owned subsidiary of Aurora.

    In  the  opinion of  the  Company, the  accompanying  unaudited consolidated
financial  statements  contain  all  adjustments  (consisting  only  of   normal
recurring  accruals) necessary to present fairly,  in all material respects, the
financial position as of  May 31, 1995,  and the results  of operations and  the
cash  flows for the three  months ended May 31, 1994  and 1995. These results of
operations are not necessarily indicative of the results to be expected for  the
full year due to certain seasonality factors and the effects and timing of large
service projects.

    Certain  information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting  principles
have  been  omitted.  These condensed  financial  statements should  be  read in
conjunction with the consolidated financial statements and the notes included in
the Company's financial statements for the fiscal year ended February 28,  1995,
which are included elsewhere in this Prospectus.

NATURE OF BUSINESS

    Aurora  Environmental Inc.  and its subsidiary  are environmental consulting
firms providing  assessment,  monitoring, training,  analytical  and  management
services  for environmental  projects. These  services are  provided nation-wide
through a  network  of  regional  offices.  Because  the  Company  conducts  its
operations in a single industry, segment information is not presented.

RECLASSIFICATIONS

    Certain  reclassifications have  been made  to the  prior period's financial
statements to conform to the current years presentation.

NOTE B -- MERGER OF ATC AND AURORA
    Aurora and ATC were merged pursuant to an agreement ("the Merger Agreement")
approved by a majority of  shareholders of each company  on June 29, 1995,  with
ATC  being the surviving corporation. Under  the Merger Agreement, ATC exchanged
 .545 of a  share of ATC  stock for each  of Aurora's 6,131,104  shares of  stock
outstanding. ATC's common shares held by Aurora of 3,258,000 were cancelled. The
merger  will be  accounted for in  a manner  similar to a  pooling of interests.
Under this method of accounting, recorded assets and liabilities of Aurora  will
be  combined with ATC and the results of  operations of ATC and Aurora will also
be combined as of the effective date  of the merger. After the merger, ATC  will
be   able  to  utilize  Aurora's  net  operating  loss  carryforward,  which  is
approximately $970,000 at May  31, 1995. In  addition, the intercompany  balance
between ATC and Aurora was forgiven.

                          INDEPENDENT AUDITOR'S REPORT

    To the Board of Directors and
Shareholders of Con-Test, Inc.
East Longmeadow, Massachusetts

    I  have  audited the  accompanying balance  sheets of  Con-Test, Inc.  as of
December 31,  1993  and 1992,  and  the  related statements  of  operations  and
retained  earnings  and cash  flows for  the years  then ended.  These financial
statements are the responsibility of the Company's management. My responsibility
is to express an opinion on these financial statements based on my audits.

    I conducted  my  audits  in  accordance  with  generally  accepted  auditing
standards.  Those standards require that I 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.
I believe that my audits provide a reasonable basis for my opinion.

    In my opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Company as of December  31,
1993  and 1992,  and the results  of its operations  and its cash  flows for the
years then ended in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ACCOUNTING POLICIES

    A.  METHOD OF ACCOUNTING AND INCOME TAXES

           The financial statements have been  prepared using the accrual  basis
       of accounting. The Company files its income tax returns on the cash basis
       whereby  revenue  associated  with  trade  accounts  receivable  will  be
       recognized when payments are received and various operating payables will
       be deducted  when  payments  are  made. In  addition,  there  are  timing
       differences in the treatment of depreciation and bad debt expense.

           The  Company has elected to be taxed as a Subchapter S Corporation in
       accordance with the appropriate provisions of the IRS Code.  Accordingly,
       for  federal tax purposes, earnings and/or losses will be included in the
       personal returns of  the stockholders. Thus,  the Company will  generally
       not  incur tax obligations at the  federal level. For state purposes, the
       tax treatment  will vary  depending on  the tax  laws of  the states  the
       Company  does business in.  The provision for  state taxes reflects those
       taxes the Company has liability to pay at the corporate level.

    B.  REVENUE

           Revenue is recognized  as services are  rendered, in accordance  with
       generally accepted accounting principles.

    C.  WORK IN PROCESS

           Work   in  process  represents   management's  estimate  of  services
       performed and unbilled at year end.

    D.  PROPERTY AND EQUIPMENT

           Property  and  equipment  are   carried  at  cost  less   accumulated
       depreciation and amortization. Depreciation and amortization are computed
       primarily  using the straight-line method over the estimated useful lives
       of the assets as follows:

<TABLE>
<S>                                         <C>
                                            8-10
Equipment.................................  years
Furniture and fixtures....................  5-7 years
Motor vehicles............................  5 years
Leasehold improvements....................  15 years
</TABLE>

           Maintenance and  repairs  are  charged  to  operations  as  incurred.
       Additions  and betterments  are capitalized. The  cost of  assets sold or
       retired  and  the  related   amounts  of  accumulated  depreciation   are
       eliminated  from  the accounts  in the  year of  sale or  retirement. Any
       resulting profit or loss is reflected currently in the income statement.

           Furniture, fixtures and equipment have  been pledged as security  for
       debt.

NOTE 2 -- FURNITURE, FIXTURES AND EQUIPMENT

        The major categories of assets are as follows:

ITEM 15:  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The  Company's Certificate of  Incorporation contains a  provision which, in
substance, eliminates the personal liability of the directors to the Company and
its stockholders for monetary damages for breaches of their fiduciary duties  as
directors  to the fullest  extent permitted by  Delaware law. By  virtue of this
provision, under current  Delaware law  a director of  the Company  will not  be
personally  liable for monetary damages for breach of his fiduciary duty, except
for liability for (a)  breach of his duty  of loyalty to the  Company or to  its
stockholders,  (b)  acts  or  omissions  not  in  good  faith  or  that  involve
intentional misconduct or  a knowing violation  of law, (c)  dividends or  stock
repurchases  or redemptions  that are unlawful  under Delaware laws  and (d) any
transaction from which he receives an improper personal benefit. This  provision
pertains only to breaches of duty by directors as directors and not in any other
corporate  capacity, such as officers, and limits liability only for breaches of
fiduciary duties under Delaware  corporate law and not  for violations of  other
laws  such as the federal securities laws. As  a result of the inclusion of such
provision, stockholders  may  be  unable to  recover  monetary  damages  against
directors  for  actions  taken  by  them  that  constitute  negligence  or gross
negligence or that are in violation  of their fiduciary duties, although it  may
be  possible to obtain injunctive or other equitable relief with respect to such
actions. The  inclusion  of  this  provision in  the  Company's  Certificate  of
Incorporation  may  have the  effect of  reducing  the likelihood  of derivative
litigation against  directors,  and  may discourage  or  deter  stockholders  or
Management from bringing a lawsuit against directors for breach of their duty of
care, even though such an action, if successful, might otherwise have benefitted
the Company and its stockholders.

    The   General  Corporation  Law  of   Delaware  provides  generally  that  a
corporation may indemnify any person who was  or is a party to or is  threatened
to  be made  a party  to any  threatened, pending  or completed  action, suit or
proceeding, whether civil, criminal, administrative, or investigative in  nature
to  procure a judgment in its  favor, by reason of the fact  that he is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of  the corporation  as a director,  officer, employee  or agent  of
another  corporation,  partnership, joint  venture,  trust or  other enterprise,
against expenses (including attorneys' fees) and,  in a proceeding not by or  in
the  right of the corporation, judgments,  fines and amounts paid in settlement,
actually and  reasonably  incurred  by  him in  connection  with  such  suit  or
proceeding,  if he acted in good faith and in  a manner believed to be in or not
opposed to the best interests of the corporation,

                                      II-1
<PAGE>
and, with respect to any criminal action or proceeding, had no reason to believe
his conduct was unlawful. Delaware law further provides that a corporation  will
not  indemnify any person against expenses incurred in connection with an action
by or in the right of the corporation if such person shall have been adjudged to
be liable for negligence  or misconduct in  the performance of  his duty to  the
corporation unless and only to the extent that the court in which such action or
suit was brought shall determine that, despite the adjudication of liability but
in  view  of  all the  circumstances  of the  case,  such person  is  fairly and
reasonably entitled to indemnity  for the expenses which  such court shall  deem
proper.

    The  indemnification  and advancement  of expenses  provided by,  or granted
pursuant to Delaware  Corporation Law is  not be deemed  exclusive of any  other
rights  to which  those seeking  indemnification or  advance of  expenses may be
entitled under  any  bylaw, agreement,  vote  of stockholders  of  disinterested
directors  or otherwise, both  as to action  in his official  capacity and as to
action in another capacity while holding such office.

    Article IX of the Company's By-Laws provides that the officers and directors
of the  Company shall  be  entitled to  indemnification  to the  maximum  extent
permitted by Delaware law.

    The  Company has entered  into indemnification agreements  with officers and
directors of the  Company and  its subsidiaries (the  "Indemnitee") wherein  the
Company  has agreed to hold such officer  and director harmless and to indemnify
each person  from and  against any  and all  judgments, fines,  amounts paid  in
settlements  and expenses, including attorneys' fees, incurred as a result of or
in connection  with  any  threatened,  pending  or  completed  action,  suit  or
proceeding,  whether civil,  criminal, administrative  or investigative  or as a
result of or in connection with any appeal therein, whether or not such  action,
suit  proceeding is by or in  the right of any other  corporation of any type or
kind, domestic or foreign,  or any partnership,  joint venture, trust,  employee
benefit  plan or other enterprise which the Indemnitee serves in any capacity at
the request of the Company, to which Indemnitee is, was or at any time becomes a
party, or is threatened to be made a party or as a result of or by reason of the
fact that Indemnitee is, was or at any time becomes a director or officer of the
Company, or is or was  serving or at any  time services such other  corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise, in
any  capacity, whether arising out of any breach of Indemnitee's fiduciary duty,
under any state  or federal law  or otherwise as  a director or  officer of  the
Company  or as a director, officer, employee or agent of such other corporation,
partnership, joint venture,  trust, employee benefit  plan or other  enterprise;
provided,  however, that no indemnity pursuant to the indemnification agreements
shall be paid by the Company (1) except to the extent the aggregate of losses to
be indemnified  exceeds  the amount  of  such  losses for  which  Indemnitee  is
actually  paid pursuant to any insurance purchased and maintained by the Company
for the  benefit of  Indemnitee; (2)  if judgment  or other  final  adjudication
established  that the Indemnitee's acts were committed  in bad faith or were the
result of dishonesty  so adjudicated,  or that Indemnitee  personally gained  in
fact  a financial profit or other advantage  to which Indemnitee was not legally
entitled; or (3)  if a  final judgment  by a  court having  jurisdiction in  the
matter  or the Court of Chancery shall determine that Indemnitee is not entitled
to such  indemnification. Insofar  as  indemnification for  liabilities  arising
under the Act may be permitted to directors, officers or persons controlling the
Company pursuant to the foregoing provisions, the Company has been informed that
in  the opinion of the Securities  and Exchange Commission, such indemnification
is against public policy as expressed in the Securities Act of 1933, as amended,
(the "Act") and is therefore unenforceable.

On behalf of the Several
Underwriters named in
Schedule I attached hereto.

Ladies and Gentlemen:

    ATC  Environmental Inc., a Delaware  corporation (the "Company") and certain
Stockholders of  the Company  set  forth on  Schedule  II attached  hereto  (the
"Selling Stockholders"), propose to sell to you and the other underwriters named
in  Schedule I attached hereto (the "Underwriters"),  for whom you are acting as
the Representatives, an aggregate of 2,400,000 shares (the "Firm Shares") of the
Company's Common Stock, $.01 par value  per share (the "Common Stock") of  which
1,700,000 shares (the "Company Shares") are to be issued and sold by the Company
and  700,000 shares  (the "Selling  Stockholder Shares") are  to be  sold by the
Selling Stockholders. The obligation  of each Selling  Stockholder to sell  Firm
Shares  shall be as set forth opposite  his name on Schedule II attached hereto.
In addition, the  Company proposes  to grant to  the Underwriters  an option  to
purchase  up to  an additional 360,000  shares (the "Option  Shares"), of Common
Stock for the purpose of covering over-allotments in connection with the sale of
the Firm Shares. The Firm Shares and  the Option Shares are together called  the
"Shares."

    1.   SALE AND PURCHASE OF THE SHARES.   On the basis of the representations,
warranties and agreements contained in, and subject to the terms and  conditions
of, this Agreement:

        (a)  The Company  agrees to  issue and sell  the Company  Shares and the
    Selling Stockholders, severally and not jointly, agrees to sell the  Selling
    Stockholder Shares to the several Underwriters, and each of the Underwriters
    agrees,  severally and  not jointly, to  purchase at the  purchase price per
    share of Common Stock of $      (the "Initial Price"), the aggregate  number
    of  Firm Shares  set forth  opposite such  Underwriter's name  in Schedule I
    attached hereto. The  Underwriters agree  to offer  the Firm  Shares to  the
    public as set forth in the Prospectus.

        (b) The Company grants to the several Underwriters an option to purchase
    all  or any  part of  the 360,000  Option Shares  at the  Initial Price. The
    number of Option  Shares to be  purchased by each  Underwriter shall be  the
    same  percentage (adjusted by the  Representative to eliminate fractions) of
    the total number  of Option Shares  to be purchased  by the Underwriters  as
    such  Underwriter  is purchasing  of  the Firm  Shares.  Such option  may be
    exercised only to cover over-allotments in  the sales of the Firm Shares  by
    the  Underwriters and may be exercised in whole or in part at any time on or
    before 12:00 noon, New York City time,  on the business day before the  Firm
    Shares  Closing Date  (as defined below),  and from time  to time thereafter
    within 30 days after the date of this Agreement, upon written or telegraphic
    notice, or verbal or telephonic  notice confirmed by written or  telegraphic
    notice,  by the Representative to the Company  no later than 12:00 noon, New
    York City time, on the business day  before the Firm Shares Closing Date  or
    at least two business days before any Option Shares Closing Date (as defined
    below),  as the case may be, setting forth the number of Option Shares to be
    purchased and the time and date (if other than the Firm Shares Closing Date)
    of such purchase.
<PAGE>
    2.   DELIVERY  AND  PAYMENT.    Delivery by  the  Company  and  the  Selling
Stockholders  of  the  Firm Shares  to  the Representatives  for  the respective
accounts of the Underwriters, and payment of the purchase price by certified  or
official  bank check  or checks  payable in New  York Clearing  House (next day)
funds to  the Company  and the  Selling Stockholders,  shall take  place at  the
offices of Rodman & Renshaw, Inc., at One Liberty Plaza, 165 Broadway, New York,
New  York, 10006, at 10:00  a.m., New York City time,  on the third business day
following the date on which the public offering of the Shares commences  (unless
such  date is postponed in accordance with  the provisions of Section 10(b)), or
at such time and place on such other date, not later than 10 business days after
the date of this Agreement, as shall be agreed upon by the Company, the  Selling
Stockholders and the Representatives (such time and date of delivery and payment
are  called the "Firm Shares  Closing Date"). The public  offering of the Shares
shall be deemed to have commenced at the  time, which is the earlier of (a)  the
time,  after the Registration Statement (as  defined in Section 4 below) becomes
effective, of  the  release  by  you for  publication  of  the  first  newspaper
advertisement  which is subsequently published relating to the Shares or (b) the
time, after the Registration  Statement becomes effective,  when the Shares  are
first  released by you for offering by  the Underwriters or dealers by letter or
telegram.

    In the event  the option  with respect to  the Option  Shares is  exercised,
delivery  by the  Company of  the Option Shares  to the  Representatives for the
respective accounts of  the Underwriters and  payment of the  purchase price  by
certified  or official bank check  or checks payable in  New York Clearing House
(next day) funds  to the Company  shall take place  at the offices  of Rodman  &
Renshaw, Inc. specified above at the time and on the date (which may be the same
date  as, but in no  event shall be earlier than,  the Firm Shares Closing Date)
specified in the  notice referred  to in  Section 1(b)  (such time  and date  of
delivery  and  payment is  called the  "Option Shares  Closing Date").  The Firm
Shares  Closing  Date  and   the  Option  Shares   Closing  Dates  are   called,
individually, a "Closing Date" and, together, the "Closing Dates."

    Certificates  evidencing the  Shares shall be  registered in  such names and
shall be in such denominations as the Representatives shall request at least two
full business days  before the  Firm Shares Closing  Date or  the Option  Shares
Closing  Date,  as  the  case  may  be,  and  shall  be  made  available  to the
Representatives for checking and  packaging, at such place  as is designated  by
the  Representatives, on  the full business  day before the  Firm Shares Closing
Date or the Option Shares Closing Date, as the case may be.

    3.  PUBLIC OFFERING.   The Company and  the Selling Stockholders  understand
that  the Underwriters propose to  make a public offering  of the Shares, as set
forth in and pursuant to the Prospectus (as defined in Section 4 below), as soon
after the effective  date of  the Registration Statement  and the  date of  this
Agreement  as the  Representatives deem advisable.  The Company  and the Selling
Stockholders  hereby  confirm  that  the  Underwriters  and  dealers  have  been
authorized  to distribute or cause to be distributed each preliminary prospectus
and are authorized to distribute the Prospectus (as from time to time amended or
supplemented if the Company furnishes  amendments or supplements thereto to  the
Underwriters).

    4.     REPRESENTATIONS  AND  WARRANTIES  OF  THE  COMPANY  AND  THE  SELLING
STOCKHOLDERS.

        (a) The Company represents and warrants to, and agrees with, the several
    Underwriters that:

           (i) The Company has filed with the Securities and Exchange Commission
       (the "Commission") a registration  statement, and may  have filed one  or
       more  amendments  thereto,  on  Form  S-2  (Registration  No.  33-61921),
       including in  such  registration  statement and  each  such  amendment  a
       related  preliminary  prospectus  (a "Preliminary  Prospectus"),  for the
       registration of the Shares and the Option Shares, in conformity with  the
       requirements  of the Securities  Act of 1933, as  amended (the "Act"). In
       addition, the Company has filed or will promptly file a further amendment
       to such registration statement, in the form heretofore delivered to  you.
       As  used in this Agreement, the  term "Registration Statement" means such
       registration statement, as amended,  on file with  the Commission at  the
       time   such  registration  statement  becomes  effective  (including  the
       prospectus, financial statements, exhibits, and all other documents filed
       as a part  thereof or  incorporated by reference  directly or  indirectly
       therein   (such   incorporated   documents   being   herein  collectively
       "Incorporated Documents")), provided that such Registration Statement, at
       the time it becomes effective, may omit such information as is  permitted
       to be omitted from the Registration Statement

                                       2
<PAGE>
       when  it becomes effective pursuant to Rule 430A of the General Rules and
       Regulations  promulgated  under  the   Act  (the  "Regulations"),   which
       information  ("Rule 430 Information")  shall be deemed  to be included in
       such Registration Statement  when a  final prospectus is  filed with  the
       Commission  in accordance  with Rules  430A and  424(b)(1) or  (4) of the
       Regulations; the  term  "Preliminary Prospectus"  means  each  prospectus
       included in the Registration Statement, or any amendments thereto, before
       it  becomes effective under the Act, the form of prospectus omitting Rule
       430A Information included in the  Registration Statement when it  becomes
       effective, if applicable (the "Rule 430A Prospectus"), and any prospectus
       filed  by the Company  with your consent  pursuant to Rule  424(a) of the
       Regulations;  and  the  term  "Prospectus"  means  the  final  prospectus
       included  as  part  of the  Registration  Statement, except  that  if the
       prospectus  relating  to  the  securities  covered  by  the  Registration
       Statement  in the  form first  filed on  behalf of  the Company  with the
       Commission pursuant to Rule 424(b)  of the Regulations shall differ  from
       such final prospectus, the term "Prospectus" shall mean the prospectus as
       filed  pursuant to Rule 424(b) from and  after the date on which it shall
       have first been used.

           (ii) When the  Registration Statement becomes  effective, and at  all
       times  subsequent thereto to and including  the Closing Dates, and during
       such longer period as the Prospectus  may be required to be delivered  in
       connection  with sales by the Underwriters  or a dealer, the Registration
       Statement (and any post-effective  amendment thereto) and the  Prospectus
       (as  amended or as supplemented if the  Company shall have filed with the
       Commission any amendment or supplement  to the Registration Statement  or
       the  Prospectus) will  contain all  statements which  are required  to be
       stated therein  in accordance  with  the Act  and the  Regulations,  will
       comply  with the Act and the Regulations, and will not contain any untrue
       statement of a material fact or omit to state any material fact  required
       to  be stated  therein or  necessary to  make the  statements therein not
       misleading, and no event  will have occurred which  should have been  set
       forth  in an amendment or supplement to the Registration Statement or the
       Prospectus which has  not then  been set forth  in such  an amendment  or
       supplement;  if a  Rule 430A Prospectus  is included  in the Registration
       Statement at the time it becomes effective, the Prospectus filed pursuant
       to  Rules  430A  and  424(b)(1)  or  (4)  will  contain  all  Rule   430A
       Information;  and each Preliminary Prospectus, as  of the date filed with
       the Commission, did not include any  untrue statement of a material  fact
       or  omit to  state any  material fact  required to  be stated  therein or
       necessary to make the statements  therein not misleading; except that  no
       representation  or warranty is made in this Section 4(a)(ii) with respect
       to statements or omissions made in  reliance upon and in conformity  with
       written  information furnished to  the Company as  stated in Section 7(b)
       with respect  to any  Underwriter by  or on  behalf of  such  Underwriter
       through  the Representatives  expressly for inclusion  in any Preliminary
       Prospectus,  the  Registration  Statement,  or  the  Prospectus,  or  any
       amendment  or  supplement  thereto. Each  of  the  Incorporated Documents
       complies in all material respects with the requirements of the Securities
       Exchange Act of 1934, as amended (the "Exchange Act"), and the rules  and
       regulations thereunder.

          (iii)  Neither  the  Commission  nor  the  "blue  sky"  or  securities
       authority of  any  jurisdiction has  issued  an order  (a  "Stop  Order")
       suspending the effectiveness of the Registration Statement, preventing or
       suspending  the use  of any  Preliminary Prospectus,  the Prospectus, the
       Registration Statement, or any amendment or supplement thereto,  refusing
       to  permit the effectiveness of the Registration Statement, or suspending
       the registration or qualification of the Firm Shares or the Option Shares
       nor has any of such authorities instituted or threatened to institute any
       proceedings with respect to a Stop Order.

           (iv) Any contract, agreement, instrument, lease, or license  required
       to  be described in the Registration Statement or the Prospectus has been
       properly described therein. Any contract agreement, instrument, lease, or
       license required to be filed as an exhibit to the Registration  Statement
       has  been  filed  with  the  Commission as  an  exhibit  to  or  has been
       incorporated as an exhibit by reference into the Registration Statement.

                                       3

           (v) The  Company  has no  subsidiary  or subsidiaries  and  does  not
       control,  directly  or  indirectly, any  corporation,  partnership, joint
       venture, association  or other  business organization,  except for  those
       permitted  to be excluded pursuant to  Item 601, Exhibit 21 of Regulation
       S-K or those disclosed  under Exhibit 21 to  the Company's Form 10-K  for
       the  fiscal year ended  February 28, 1995  on page 56  thereof (each such
       corporation singly a "Subsidiary"  and collectively the  "Subsidiaries").
       Each  of the Company and each Subsidiary is a corporation duly organized,
       validly existing, and in good standing under the laws of the state of its
       incorporation, with full corporate power and authority, and all necessary
       consents, authorizations, approvals, orders, licenses, certificates,  and
       permits  of and  from, and  declarations and  filings with,  all federal,
       state, local, and other governmental authorities and all courts and other
       tribunals, to own, lease, license, and use its properties and assets  and
       to  carry  on its  business  as now  being  conducted and  in  the manner
       described in the Prospectus. Each of the Company and each Subsidiary  has
       been  duly  qualified to  do business  and  is in  good standing  in each
       jurisdiction in which  its respective ownership,  leasing, licensing,  or
       character,  location or use of property and  assets or the conduct of its
       respective business  makes  such  qualification  necessary.  Neither  the
       Company  nor  any Subsidiary  owns, leases  or  licenses any  property or
       conducts any business outside the United States of America.

           (vi)  The  authorized  capital  stock  of  the  Company  consists  of
       20,000,000  shares  of  Common  Stock, of  which  [5,857,390]  shares are
       outstanding. Each outstanding  share of  Common Stock has  been duly  and
       validly  authorized and  issued, fully paid,  and non-assessable, without
       any personal liability  attaching to  the ownership thereof  and has  not
       been  issued and  is not  owned or  held in  violation of  any preemptive
       rights of stockholders.  The Company owns  all of the  shares of  capital
       stock  of the Subsidiaries, free and clear of all liens, claims, security
       interests, restrictions, stockholders' agreements, voting trusts and  any
       other  encumbrances whatsoever. There is  no commitment, plan, preemptive
       right or arrangement  to issue,  and no outstanding  option, warrant,  or
       other  right calling for the issuance of,  shares of capital stock of the
       Company or any of  the Subsidiaries or any  security or other  instrument
       which  by its terms is convertible into, exercisable for, or exchangeable
       for capital stock of  the Company or any  of the Subsidiaries, except  as
       may  be properly  described in  the Prospectus.  There is  outstanding no
       security or other instrument  which by its terms  is convertible into  or
       exchangeable for capital stock of the Company or any of the Subsidiaries,
       except as may be properly described in the Prospectus.

          (vii) The consolidated financial statements of the Company included in
       the Registration Statement and the Prospectus fairly present with respect
       to the Company the financial position, the results of operations, and the
       other  information purported to be shown  therein at the respective dates
       and for  the  respective periods  to  which they  apply.  Such  financial
       statements  have  been  prepared in  accordance  with  generally accepted
       accounting  principles  (except  to  the  extent  that  certain  footnote
       disclosures regarding any stub period may have been omitted in accordance
       with  the  applicable rules  of the  Commission  under the  Exchange Act)
       consistently applied  throughout the  periods involved,  are correct  and
       complete,  and  are  in accordance  with  the  books and  records  of the
       Company. The accountants whose report on the audited financial statements
       is filed with the Commission as a part of the Registration Statement are,
       and during  the  periods  covered  by their  report(s)  included  in  the
       Registration  Statement  and the  Prospectus were,  independent certified
       public accountants with respect to the Company within the meaning of  the
       Act  and the Regulations.  No other financial  statements are required by
       Form S-2 or otherwise to be included in the Registration Statement or the
       Prospectus. There has at  no time been a  material adverse change in  the
       financial condition, results of operations, business, properties, assets,
       liabilities,   or  future  prospects  of  the   Company  or  any  of  the
       Subsidiaries from the  latest information set  forth in the  Registration
       Statement  or the Prospectus, except as  may be properly described in the
       Prospectus.

         (viii) There  is no  litigation,  arbitration, claim,  governmental  or
       other  proceeding (formal or informal), or investigation before any court
       or before any public  body or board pending,  threatened, or in  prospect
       (or  any  basis therefor)  with  respect to  the  Company or  any  of the
       Subsidiaries, or any of their respective operations, business, properties
       or assets, except as may be

                                       4
<PAGE>
       properly described in the  Prospectus or such as  individually or in  the
       aggregate  do not  now have and  will not  in the future  have a material
       adverse effect  upon  the  operations, business,  properties,  assets  or
       financial  condition  of the  Company and  the Subsidiaries.  Neither the
       Company nor any of the Subsidiaries is involved in any labor dispute, nor
       is such dispute threatened, which  dispute would have a material  adverse
       effect  upon the  operations, business,  properties, assets  or financial
       condition of the Company. Neither the Company nor any of the Subsidiaries
       is in  violation  of, or  in  default with  respect  to, any  law,  rule,
       regulation,  order, judgment, or decree; nor is the Company or any of the
       Subsidiaries required  to take  any action  in order  to avoid  any  such
       violation or default.

           (ix) The Company and each of the Subsidiaries has good and marketable
       title in fee simple absolute to all real properties and good title to all
       other  properties and assets which the  Prospectus indicates are owned by
       it, and has  valid and enforceable  leasehold interests in  each of  such
       items, free and clear of all liens, security interests, pledges, charges,
       encumbrances,  and mortgages (except as may  be properly described in the
       Prospectus). No  real property  owned, leased,  licensed or  used by  the
       Company  or any of the  Subsidiaries lies in an area  which is, or to the
       knowledge of the Company will be, subject to zoning, use or building code
       restrictions which would prohibit, and no state of facts relating to  the
       actions  or inaction of another person or entity or his or its ownership,
       leasing, licensing or use of any real or personal property exists or will
       exist which would  prevent, the continued  effective ownership,  leasing,
       licensing  or use of such real property in the business of the Company or
       any of  the Subsidiaries  as  presently conducted  or as  the  Prospectus
       indicates it contemplates conducting (except as may be properly described
       in the Prospectus).

           (x) The Company and each of the Subsidiaries, and to the knowledge of
       the  Company,  any other  party, is  not now  or is  not expected  by the
       Company to be in violation or breach  of, or in default with respect  to,
       complying  with  any  term,  obligation  or  provision  of  any contract,
       agreement, instrument,  lease,  license,  indenture,  mortgage,  deed  of
       trust,  note,  arrangement  or  understanding which  is  material  to the
       Company or any of the Subsidiaries or  by which any of its properties  or
       business  may be bound or affected, and  no event has occurred which with
       notice or lapse of time or both would constitute such a default, and each
       such  contract,   agreement,  instrument,   lease,  license,   indenture,
       mortgage,  deed of trust,  note, arrangement or  understanding is in full
       force and  is the  legal, valid  and binding  obligation of  the  parties
       thereto  and is enforceable as to them  in accordance with its terms. The
       Company and  each  of the  Subsidiaries  enjoy peaceful  and  undisturbed
       possession  under all  leases and licenses  under which  it is operating.
       Neither the Company nor any of the Subsidiaries is a party to or bound by
       any contract, agreement, instrument, lease, license, indenture, mortgage,
       deed of  trust, note,  arrangement or  understanding, or  subject to  any
       charter  or other restriction, which has had  or may in the future have a
       material  adverse  effect   on  the  financial   condition,  results   of
       operations, business, properties, assets, liabilities or future prospects
       of  the Company and the Subsidiaries. Neither  the Company nor any of the
       Subsidiaries is in violation or breach of, or in default with respect to,
       any term of its certificate of incorporation (or other charter  document)
       or by-laws or of any franchise, license, permit, judgment, decree, order,
       statute, rule or regulation.

           (xi)  The Company and the Subsidiaries have filed all federal, state,
       local and foreign tax returns which are required to be filed through  the
       date hereof, or have received extensions thereof, and have paid all taxes
       shown  on such returns and  all assessments received by  it to the extent
       that the same are material and have become due.

          (xii)  Any   patents,  patent   applications,  trademarks,   trademark
       applications,   trade   names,  service   marks,   copyrights,  copyright
       applications, franchises,  and  other intangible  properties  and  assets
       listed  in  the  Registration  Statement  (all  of  the  foregoing  being
       collectively herein  called  "Intangibles")  that  the  Company  and  the
       Subsidiaries  own,  possess  or have  pending,  or under  which  they are
       licensed, are in good standing and  uncontested. There is no right  under
       any  Intangible  necessary  to  the  business  of  the  Company  and  the
       Subsidiaries as presently  conducted or as  the Prospectus indicates  the
       Company  contemplates conducting  (except as may  be so  described in the
       Prospectus).  Neither  the  Company  nor  any  of  the  Subsidiaries  has
       infringed, is infringing, or

                                       5

       has  received  any  notice  of  infringement  with  respect  to  asserted
       Intangibles of  others. To  the knowledge  of the  Company, there  is  no
       infringement by others of Intangibles of the Company. To the knowledge of
       the Company, there is no Intangible of others which has had or may in the
       future  have  a materially  adverse  effect on  the  financial condition,
       results of  operations,  business,  properties,  assets,  liabilities  or
       future prospects of the Company and the Subsidiaries.

         (xiii)  Neither the Company nor  any Subsidiary, any director, officer,
       agent, employee or other  person associated with or  acting on behalf  of
       the  Company and the  Subsidiaries has, directly  or indirectly: used any
       corporate funds  for  unlawful contributions,  gifts,  entertainment,  or
       other unlawful expenses relating to political activity; made any unlawful
       payment  to foreign or  domestic government officials  or employees or to
       foreign or domestic political parties or campaigns from corporate  funds;
       violated  any provision of the Foreign  Corrupt Practices Act of 1977, as
       amended; or made any bribe, rebate, payoff, influence payment,  kickback,
       or  other unlawful payment. No transaction  has occurred between or among
       the Company, the Subsidiaries, or the Selling Stockholders and any of its
       or their officers  or directors or  any affiliates or  affiliates of  any
       such officer or director, except as described in the Prospectus.

          (xiv)  The Company has  all requisite power  and authority to execute,
       deliver and perform this  Agreement. All necessary corporate  proceedings
       of  the Company have been duly taken to authorize the execution, delivery
       and  performance  of  this  Agreement.  This  Agreement  has  been   duly
       authorized,  executed, and delivered by the  Company, is the legal, valid
       and binding  obligation of  the Company,  and is  enforceable as  to  the
       Company   in  accordance  with  its  terms.  No  consent,  authorization,
       approval,  order,  license,  certificate  or   permit  of  or  from,   or
       declaration   or  filing  with,  any   federal,  state,  local  or  other
       governmental authority or any court or other tribunal is required by  the
       Company or the Subsidiaries for the execution, delivery or performance by
       the  Company of this  Agreement (except filings under  the Act which have
       been or will be made before the applicable Closing Date and such consents
       consisting only of  consents under  "blue sky" or  securities laws  which
       have been obtained at or prior to the date of this Agreement). No consent
       of  any  party to  any contract,  agreement, instrument,  lease, license,
       indenture, mortgage, deed of trust, note, arrangement or understanding to
       which the Company or the Subsidiaries are a party, or to which any of its
       respective  properties  or  assets  are  subject,  is  required  for  the
       execution,  delivery or performance of this Agreement, and the execution,
       delivery and performance of this Agreement, will not violate, result in a
       breach of, conflict with, accelerate the due date of any payments  under,

       trust,  note, arrangement  or understanding,  or violate  or result  in a
       breach of any term of the certificate of incorporation (or other  charter
       document)  or by-laws of the Company, or  violate, result in a breach of,
       or conflict with  any law,  rule, regulation, order,  judgment or  decree
       binding  on the  Company or any  of the  Subsidiaries or to  which any of
       their operations, business, properties or assets are subject.

       The  Firm  Shares,  when issued  and  delivered in  accordance  with this
       Agreement, and the Option Shares, when delivered in accordance with  this
       Agreement,  will  be  duly  and  validly  issued,  fully  paid,  and non-
       assessable, without  any personal  liability attaching  to the  ownership
       thereof,  and will not be issued in violation of any preemptive rights of
       stockholders, optionholders, warrantholders and any other persons and the
       Underwriters will receive  good title  to the Company  Shares and  Option
       Shares  purchased by  them, respectively,  free and  clear of  all liens,
       security  interests,   pledges,  charges,   encumbrances,   stockholders'
       agreements and voting trusts.

       to  all  statements  relating  thereto  contained  in  the   Registration
       Statement or the Prospectus.

       given in the Registration Statement and the Prospectus, and except as may
       otherwise be properly described therein, there has not been any  material
       adverse  change  in  the assets  or  properties, business  or  results of

                                       6
<PAGE>
       operations or financial  condition of  the Company  or the  Subsidiaries,
       whether  or  not  arising from  transactions  in the  ordinary  course of
       business; neither  the Company  nor the  Subsidiaries has  sustained  any
       material  loss or interference with its business or properties from fire,
       explosion, earthquake, flood or other calamity, whether or not covered by
       insurance; since the  date of the  latest balance sheet  included in  the
       Registration  Statement and the Prospectus,  except as reflected therein,

       obligation,  direct or contingent, except  for liabilities or obligations
       undertaken in the ordinary  course of business;  and neither the  Company
       nor  the  Subsidiaries  has (A)  issued  any securities  or  incurred any

       (C) declared or paid any dividend or made any distribution on any of  its
       capital  stock or redeemed, purchased or  otherwise acquired or agreed to
       redeem, purchase or otherwise acquire any shares of its capital stock.

         (xviii) Neither  the Company  nor  any of  its officers,  directors  or
       affiliates  (as  defined in  the Regulations),  has  taken or  will take,
       directly or  indirectly, prior  to the  termination of  the  underwriting
       syndicate   contemplated  by  this  Agreement,  any  action  designed  to
       stabilize or manipulate  the price  of any  security of  the Company,  or
       which  has caused or resulted in, or which might in the future reasonably
       be expected to cause or result  in, stabilization or manipulation of  the
       price of any security of the Company, to facilitate the sale or resale of
       any of the Firm Shares or the Option Shares.

          (xix) The Company has obtained from each of its executive officers and
       directors   and  the   Selling  Stockholders,   his  enforceable  written
       agreement,  in  form  and  substance  satisfactory  to  counsel  for  the
       Underwriters,  that for a period  of 180 days from  the date on which the
       public offering of the Shares commences they will not, without your prior
       written consent, offer, pledge, sell, contract to sell, grant any  option
       for  the sale  of, or otherwise  dispose of, directly  or indirectly, any
       shares of  Common  Stock or  other  securities  of the  Company  (or  any
       security  or other  instrument which  by its  terms is  convertible into,
       exercisable for,  or exchangeable  for shares  of Common  Stock or  other
       securities  of the Company, including,  without limitation, any shares of
       Common Stock  issuable under  any employee  stock options),  beneficially
       owned  by them,  except with respect  to Shares being  sold in connection
       herewith or their being a beneficial owner of any such Shares.

          (xx) The Company is not, and  does not intend to conduct its  business
       in  a manner in which it would  be, an "investment company" as defined in
       Section 3(a)  of the  Investment  Company Act  of 1940  (the  "Investment
       Company Act").

          (xxi)  No person  or entity has  the right to  require registration of
       shares of Common Stock or other securities of the Company because of  the
       filing or effectiveness of the Registration Statement, except such person
       or  entities from whom written waivers  of such rights have been received
       prior to the date hereof.

         (xxii) Except as may  be set forth in  the Prospectus, the Company  has
       not incurred any liability for a fee, commission or other compensation on
       account  of the employment of  a broker or finder  in connection with the
       transactions contemplated by this Agreement.

       affiliates is presently  doing business  with the government  of Cuba  or
       with  any person or affiliate located in  Cuba. If, at any time after the
       date that  the  Registration Statement  is  declared effective  with  the
       Commission  or with  the Florida Department  of Banking  and Finance (the

       the  period referred to  in the first clause  of Section 4(a)(ii) hereof,

       business  in Cuba, and during the  period referred to in Section 4(a)(ii)
       hereof will inform the  Florida Department within  ninety days after  any

       Stockholder.  No  consent  of  any  party  to  any  contract,  agreement,
       instrument,  lease, license,  indenture, mortgage,  deed of  trust, note,

       party, or to which any of such Selling Stockholder's properties or assets
       are  subject, is required  for the execution,  delivery or performance of
       this Agreement;  and  the execution,  delivery  and performance  of  this
       Agreement  will not  violate, result  in a  breach of,  conflict with, or

       charges,  encumbrances,  stockholders' agreements  and voting  trusts and
       when delivered in accordance with  this Agreement, the Underwriters  will
       receive  good title to such Selling Stockholder Shares purchased by them,
       respectively, from such Selling Stockholder, free and clear of all liens,
       security  interests,   pledges,  charges,   encumbrances,   stockholders'
       agreements and voting trusts.

       Stockholder's affiliates (as  defined in  the Regulations)  has taken  or
       will  take,  directly  or indirectly,  prior  to the  termination  of the
       underwriting  syndicate  contemplated  by  this  Agreement,  any   action
       designed  to stabilize  or manipulate  the price  of any  security of the
       Company, or which has caused or resulted in, or which might in the future
       reasonably  be  expected  to  cause   or  result  in,  stabilization   or
       manipulation  of the price of any  security of the Company, to facilitate
       the sale or resale of any of such Selling Stockholder Shares.

           (v) All information furnished or to be furnished to the Company by or
       on behalf of  such Selling  Stockholder for  use in  connection with  the
       preparation  of the Registration Statement and  the Prospectus is true in
       all respects and does not and will not include any untrue statement of  a
       material  fact or omit to  state any material fact  required to be stated
       therein or necessary to make the statements therein not misleading.

<PAGE>
    respectively, the date of this Agreement and each such Closing Date, in form
    and  scope reasonably  satisfactory to the  Representatives, with reproduced
    copies  or  signed  counterparts  thereof  for  each  of  the   Underwriters
    confirming  that they are independent accountants  within the meaning of the
    Act and the Regulations,  that the response to  Item 10 of the  Registration
    Statement  is correct in so far as it  relates to them and stating in effect
    that:

           (i) in their opinion the  audited financial statements and  financial
       statement   schedules  included  or  incorporated  by  reference  in  the
       Registration Statement and the Prospectus and reported on by them  comply
       as  to  form  in all  material  respects with  the  applicable accounting
       requirements of the Act, the Exchange Act and the related published rules
       and regulations thereunder;

           (ii) on  the  basis of  a  reading of  the  amounts included  in  the
       Registration  Statement and  the Prospectus  under the  headings "Summary
       Financial  Data"  and   "Selected  Financial  Data,"   which  would   not
       necessarily  reveal matters of significance  with respect to the comments
       set forth in such letter, a reading of the minutes of the meetings of the
       stockholders and  directors  of the  Company,  and inquiries  of  certain
       officials  of  the  Company  who have  responsibility  for  financial and
       accounting  matters  of  the  Company  as  to  transactions  and   events
       subsequent to the date of the latest audited financial statements, except
       as  disclosed in the  Registration Statement and  the Prospectus, nothing
       came to their attention which caused them to believe that:

               (A) the  amounts  in  "Summary  Financial  Data,"  and  "Selected
           Financial   Data"  included  or  incorporated  by  reference  in  the
           Registration Statement  and  the Prospectus  do  not agree  with  the
           corresponding  amounts in the audited financial statements from which
           such amounts were derived; or

               (B) with respect to the Company, there were, at a specified  date
           not more than five business days prior to the date of the letter, any
           decreases  in net sales, income before income taxes and net income or
           any increases in long-term  debt of the Company  or any decreases  in
           the capital stock, working capital or the stockholders' equity in the
           Company,  as compared with the amounts shown on the Company's audited
           Balance Sheet for the fiscal year ended February 28, 1995 included in
           the Registration Statement  or the audited  Statement of  Operations,
           for such year; and

          (iii)  they have  performed certain  other procedures  as a  result of
       which they determined  that information  of an  accounting, financial  or
       statistical   nature  (which  is  limited  to  accounting,  financial  or
       statistical information derived  from the general  accounting records  of
       the  Company) set forth in the  Registration Statement and the Prospectus
       and reasonably specified by the Representative agrees with the accounting

paragraph  (e) are to such documents as  amended and supplemented at the date of

        (f) The Representatives shall  have received on  each Closing Date  from
    Lester  Morse P.C.,  counsel for the  Company, an opinion,  addressed to the
    Representatives  and  dated  such  Closing  Date,  and  in  form  and  scope
    satisfactory  to  counsel for  the Underwriters,  with reproduced  copies or
    signed counterparts  thereof for  each of  the Underwriters,  to the  effect
    that:

           (i)  The  Company  has no  subsidiary  or subsidiaries  and  does not
       control, directly  or  indirectly, any  corporation,  partnership,  joint
       venture,  association or  other business  organization, except  for those
       permitted to be excluded pursuant to  Item 601, Exhibit 21 or  Regulation
       S-K.  Each  of the  Company  and each  Subsidiary  is a  corporation duly
       organized, validly existing, and in good  standing under the laws of  the
       State of Delaware, with full corporate power and authority to own, lease,
       license  and use its properties and assets and to conduct its business in
       the manner described in the Prospectus. To the knowledge of such counsel,
       the  Company  has  all  necessary  consents,  authorizations,  approvals,
       orders,  certificates  and  permits  of and  from,  and  declarations and
       filings  with,  all   federal,  state,  local   and  other   governmental
       authorities  and all courts  and other tribunals,  to own, lease, license
       and use its  properties and  assets and to  conduct its  business in  the
       manner

                                       10
<PAGE>
       described  in the Prospectus. Each of  the Company and each Subsidiary is
       duly qualified to  do business  and is in  good standing,  in each  state
       where the failure to be so qualified could have a material adverse effect
       on  the operating condition (financial and  otherwise) or business of the
       Company. Neither the Company nor any Subsidiary owns, leases or  licenses
       any  property  or  conducts any  business  outside the  United  States of
       America. Except as  set forth in  or incorporated by  reference into  the
       Registration Statement, the Company has no subsidiary or subsidiaries and
       does  not control, directly or  indirectly, any corporation, partnership,
       joint venture,  association or  other business  organization, other  than
       those  permitted  to be  excluded  pursuant to  Item  601, Exhibit  21 or
       Regulation S-K.

           (ii) The Company has authorized, issued and outstanding capital stock
       as set forth under  the caption "Capitalization"  in the Prospectus.  The
       certificates evidencing the shares are in due and proper legal form. Each
       outstanding  share of Common  Stock has been  duly and validly authorized
       and  issued,  fully  paid,  and  non-assessable,  without  any   personal
       liability attaching to the ownership thereof, and has not been issued and
       is   not  owned  or  held  in   violation  of  any  preemptive  right  of
       stockholders. The Company owns all of the shares of capital stock of  the
       Subsidiaries,  free and clear  of all lines,  claims, security interests,
       restrictions, stockholders'  agreements,  voting  trusts  and  any  other
       encumbrances  whatsoever. To the  knowledge of such  counsel, there is no
       commitment, plan, or  arrangement to  issue, and  no outstanding  option,
       warrant, or other right calling for the issuance of, any share of capital
       stock  of the Company or any of the Subsidiaries or any security or other
       instrument which by its  terms is convertible  into, exercisable for,  or
       exchangeable for capital stock of the Company or any of the Subsidiaries,
       except  as may be properly described  in the Prospectus. To the knowledge
       of such counsel,  there is  outstanding no security  or other  instrument
       which  by its terms is convertible  into, exercisable for or exchangeable
       for capital stock of  the Company or any  of the Subsidiaries, except  as
       may be properly described in the Prospectus.

          (iii)  To  the  knowledge of  such  counsel, there  is  no litigation,
       arbitration,  claim,  governmental   or  other   proceeding  (formal   or
       informal), or investigation before any court or before any public body or
       board  pending, threatened, or  in prospect (or  any basis therefor) with
       respect to the  Company or any  of the Subsidiaries,  any of the  Selling
       Stockholders   or  any   of  their   respective  operations,  businesses,
       properties, assets,  or financial  condition except  as may  be  properly
       described  in the Prospectus or such  as individually or in the aggregate
       do not now have and are not in the future reasonably forseeable to have a
       material  adverse  effect  upon  the  operations,  business,  properties,
       assets,  or financial condition  of the Company  and the Subsidiaries. To
       the knowledge of such counsel, neither the Company nor any of the Selling
       Stockholders is  involved  in any  labor  dispute, nor  is  such  dispute
       threatened,  which dispute would have a  material adverse effect upon the
       operations, business, properties,  assets or financial  condition of  the
       Company   and  the  Subsidiaries.   Neither  the  Company,   any  of  the
       Subsidiaries nor any of the Selling  Stockholders is in violation of,  or
       in  default with respect to, any  law, rule, regulation, order, judgment,
       or decree, except as may be properly described in the Prospectus or  such
       as  in the aggregate  do not now have  and will not in  the future have a
       material  adverse  effect  upon  the  operations,  business,  properties,
       assets,  or financial condition  of the Company  and of the Subsidiaries;
       nor is  the Company,  any of  the  Subsidiaries nor  any of  the  Selling
       Stockholders  required  to take  any action  in order  to avoid  any such
       violation or default.

           (iv) To the knowledge  of such counsel, neither  the Company, any  of
       the Subsidiaries nor any other party is now or is expected by the Company
       or any of the Selling Stockholders to be in violation or breach of, or in
       default with respect to, complying with any term, obligation or provision
       of  any  contract,  agreement,  instrument,  lease,  license,  indenture,
       mortgage, deed  of trust,  note, arrangement  or understanding  which  is
       material  to the Company  or any of  the Subsidiaries or  by which any of
       their respective properties or businesses may be bound or affected and no
       event has  occurred which  with notice  or lapse  of time  or both  would
       constitute such a default.

                                       11
<PAGE>
           (v)  Neither the Company nor any  of the Subsidiaries is in violation
       or breach of, or in default with respect to, any term of its  certificate
       of incorporation (or other charter document) or by-laws.

           (vi)   Each  of  the  Company,   the  Subsidiaries  and  the  Selling
       Stockholders has all  requisite power and  authority to execute,  deliver
       and  perform  this  Agreement  and  to issue  and  sell  the  Shares. All
       necessary corporate proceedings of the Company and the Subsidiaries  have
       been  taken to authorize  the execution, delivery  and performance by the
       Company of  this  Agreement. This  Agreement  has been  duly  authorized,
       executed   and  delivered  by  each  of   the  Company  and  the  Selling
       Stockholders, is the legal, valid and  binding obligation of each of  the
       Company  and each of the Selling  Stockholders and (subject to applicable
       bankruptcy, insolvency, and  other laws affecting  the enforceability  of
       creditors'  rights  generally)  is  enforceable  as  to  the  Company  in
       accordance with its  terms. No consent,  authorization, approval,  order,
       license, certificate or permit of or from, or declaration or filing with,
       any  federal state, local or other governmental authority or any court or
       other tribunal is required by the Company, the Subsidiaries or any of the
       Selling Stockholders, for the execution,  delivery or performance by  the
       Company  or any  of the  Selling Stockholders  of this  Agreement (except
       filings under the Act which have been made prior to the Closing Date  and
       consents  consisting  only of  consents  under "blue  sky"  or securities
       laws). To the knowledge of such counsel,  no consent of any party to  any
       contract,  agreement,  instrument, lease,  license,  indenture, mortgage,
       deed of trust, note, arrangement  or understanding to which the  Company,
       the  Subsidiaries or any of  the Selling Stockholders are  a party, or to
       which any  of  their respective  properties  or assets  are  subject,  is
       required  for the execution,  delivery or performance  of this Agreement;
       and the execution, delivery  and performance of  this Agreement will  not
       violate,  result in a breach  of, conflict with, or  (with or without the
       giving of notice or  the passage of  time or both)  entitle any party  to
       terminate   or  call  a  default  under  any  such  contract,  agreement,
       instrument, lease,  license, indenture,  mortgage, deed  of trust,  note,
       arrangement  or understanding,  in each  case known  to such  counsel, or
       violate or  result  in  a  breach  of any  term  of  the  certificate  of
       incorporation  (or other charter document) or  by-laws of the Company, or
       violate, result  in  a  breach  of,  or  conflict  with  any  law,  rule,
       regulation, order, judgment, or decree binding on the Company, any of the
       Subsidiaries  or any of the Selling Stockholders or to which any of their
       respective operations, businesses, properties or assets are subject.

          (vii) The  Firm Shares  and the  Option Shares  are duly  and  validly
       authorized.  Such opinion  delivered at each  of the  Closing Dates shall
       state that each Share, as the case  may be, to be delivered on that  date
       is  duly  and validly  issued, fully  paid,  and non-assessable,  with no
       personal liability attaching to the ownership thereof, and is not  issued
       in   violation  of  any  preemptive   rights  of  stockholders,  and  the
       Underwriters have received good  title to the  Shares purchased by  them,
       respectively,  from the Company and each  of the Selling Stockholders, as
       applicable, for the consideration contemplated  herein and in good  faith
       and without notice of any adverse claim within the meaning of the Uniform
       Commercial  Code,  free  and  clear  of  any  liens,  security interests,
       pledges, charges, encumbrances,  stockholders' agreements, voting  trusts
       and other claims. The Common Stock, the Firm Shares and the Option Shares
       conform  to all statements relating thereto contained in the Registration
       Statement or the Prospectus.

         (viii) To  the  knowledge of  such  counsel, any  contract,  agreement,
       instrument, lease or license required to be described in the Registration
       Statement  or the Prospectus has been  properly described therein. To the
       knowledge of such counsel, any contract, agreement, instrument, lease  or
       license  required to be filed as an exhibit to the Registration Statement
       has been  filed  with  the  Commission  as an  exhibit  to  or  has  been
       incorporated as an exhibit by reference into the Registration Statement.

           (ix) Insofar as statements in the Prospectus purport to summarize the
       status  of  litigation or  the  provisions of  laws,  rules, regulations,
       orders, judgments, decrees, contracts, agreements, instruments, leases or
       licenses, such statements have been prepared or reviewed by such  counsel
       and  to the knowledge  of such counsel, accurately  reflect the status of
       such litigation and provisions purported to be summarized and are correct
       in all material respects.

                                       12
<PAGE>
           (x) The Company is not an "investment company" as defined in  Section
       3(a)  of  the Investment  Company Act  and, if  the Company  conducts its
       business as set forth in the  Prospectus, will not become an  "investment
       company"  and will not be required  to be registered under the Investment
       Company Act.

           (xi) To the knowledge  of such counsel, no  person or entity has  the
       right  to  require  registration  of  shares  of  Common  Stock  or other
       securities of the Company because of  the filing or effectiveness of  the
       Registration  Statement except such persons or entities from whom written
       waivers of such rights have been received prior to the Closing Date.

          (xii) The Registration Statement has  become effective under the  Act.
       No  Stop Order has  been issued and  no proceedings for  that purpose has
       been  instituted  or  are  threatened,  pending,  or  to  such  counsel's
       knowledge, contemplated.

         (xiii)  The Registration Statement,  any Rule 430A  Prospectus, and the
       Prospectus, and any amendment or supplement thereto (other than financial
       statements and other financial data and schedules which are or should  be
       contained  in  any thereof,  as  to which  such  counsel need  express no
       opinion),  comply  as  to  form   in  all  material  respects  with   the
       requirements  of the  Act and the  Regulations. To the  knowledge of such
       counsel, the conditions for the use of Form S-2 have been satisfied  with
       respect to the Registration Statement.

          (xiv)  Such  counsel  has  no  reason  to  believe  that  any  of  the
       Registration Statement, any Rule 430A  Prospectus, or the Prospectus,  or
       any  amendment or supplement thereto (other than financial statements and
       other financial data and  schedules which are or  should be contained  in
       any  thereof, as to which such counsel need express no opinion), contains
       any untrue statement of a material fact or omits to state a material fact
       required to be stated therein or necessary to make the statements therein
       not misleading.

          (xv) To the knowledge of such counsel, since the effective date of the
       Registration Statement, no event has occurred which should have been  set
       forth  in an amendment or supplement to the Registration Statement or the
       Prospectus which  has  not  been  set  forth  in  such  an  amendment  or
       supplement.

          (xvi)  The agreement of  each officer and director  of the Company and
       each Selling Stockholder, stating that for a period of 180 days from  the
       date  on which  the public offering  of the Shares  commences, such party
       will not,  without the  Representatives'  prior written  consent,  offer,
       pledge,  sell, contract  to sell,  grant any option  for the  sale of, or
       otherwise dispose of, directly or indirectly, any shares of Common  Stock
       (or  any  other  securities  of  the Company  or  any  security  or other
       instrument which by its  terms is convertible  into, exercisable for,  or
       exchangeable  for  shares  of Common  Stock  or other  securities  of the
       Company, including,  without  limitation,  any  shares  of  Common  Stock
       issuable  under any employee  stock options), beneficially  owned by such
       party, has been duly  and validly authorized,  executed and delivered  by
       such  party and  constitutes the legal,  valid and  binding obligation of
       such party enforceable against such party in accordance with its terms.

    In addition, such counsel shall state that such counsel has participated  in
the  preparation  of  the  Registration  Statement  and  the  Prospectus  and in
conferences  with   officers   and   other  representative   of   the   Company,
representative  of  the Representatives  and  representative of  the independent
accountants  of  the  Company,  at   which  conferences  the  contents  of   the
Registration  Statement and  the Prospectus  and related  matters were discussed
and, although such  counsel has not  independently verified and  is not  passing
upon  and does not  assume any responsibility for  the accuracy, completeness or
fairness of  the statements  contained  in the  Registration Statement  and  the
Prospectus  (except as specified in the foregoing  opinion), on the basis of the
foregoing and relying as  to materiality upon  the representations of  executive
officers  of the Company after conferring with such executive officers, no facts
have come to the attention  of such counsel which  lead such counsel to  believe
that  the Registration Statement  at the time it  became effective contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated

                                       13
<PAGE>
therein or necessary to make the statements therein not misleading, or that  the
Prospectus,  except  for  the  financial  statements  and  other  financial  and
statistical data included therein as to  which counsel need express no  opinion,
as amended or supplemented on the date thereof contained any untrue statement of
a  material fact or omitted to state a  material fact necessary in order to make
the statements therein, in the light of the circumstances under which they  were
made, not misleading.

    In rendering their opinion as aforesaid, counsel may rely upon an opinion or
opinions,  each dated the Closing Date, of other counsel retained by the Company
as to laws of any jurisdiction other than the Federal laws of the United States,
the laws of the State of New York  or the General Corporate Law of the State  of
Delaware,  provided that (1) each such local counsel is reasonably acceptable to
the Representatives  and  (2) such  reliance  is expressly  authorized  by  each
opinion  so relied  upon and  a copy of  each such  opinion is  addressed to the
Representatives and is in form and substance reasonably satisfactory to them and
their counsel. In addition, such counsel may rely, as to matters of fact, to the
extent such counsel deems proper, on certificates of responsible officers of the
Company, provided that executed copies of such certificates are provided to  the
Representatives.

        (g)  The Representatives shall have received  on the Firm Shares Closing
    Date from  Lester  Morse, P.C.,  counsel  to the  Selling  Stockholders,  an
    opinion,  addressed to the Representatives, and  dated such Closing Date, to
    the effect that:

           (i) The Selling Stockholders have  all requisite power and  authority

       Shares. This Agreement has been  duly authorized, executed and  delivered
       by  each of  the Selling  Stockholders, is  the legal,  valid and binding
       obligation of each of the Selling Stockholders and (subject to applicable
       bankruptcy, insolvency, and  other laws affecting  the enforceability  of
       creditors'  rights generally)  is enforceable as  to each  of the Selling
       Stockholders in  accordance with  its terms.  No consent,  authorization,
       approval,   order,  license,  certificate  or   permit  of  or  from,  or
       declaration  or  filing   with,  any  federal   state,  local  or   other
       governmental  authority or any court or other tribunal is required by any
       of the Selling Stockholders, for  the execution, delivery or  performance
       by  the Selling Stockholders of this  Agreement (except filings under the
       Act which  have  been  made  prior  to  the  Closing  Date  and  consents
       consisting  only of consents under "blue sky" or securities laws). To the
       knowledge of  such counsel,  no consent  of any  party to  any  contract,
       agreement,  instrument,  lease,  license,  indenture,  mortgage,  deed of
       trust, note, arrangement  or understanding  to which any  of the  Selling
       Stockholders  is a party, or to  which any of their respective properties
       or assets  are  subject,  is  required for  the  execution,  delivery  or
       performance   of  this   Agreement;  and  the   execution,  delivery  and
       performance of this Agreement  will not violate, result  in a breach  of,
       conflict with, or (with or without the giving of notice or the passage of
       time  or both) entitle any party to terminate or call a default under any
       such  contract,   agreement,  instrument,   lease,  license,   indenture,
       mortgage, deed of trust, note, arrangement or understanding, in each case
       known  to such counsel,  or violate, result  in a breach  of, or conflict
       with any law, rule, regulation, order, judgment, or decree binding on any
       of the Selling Stockholders.

           (ii) Such opinion  delivered on  the Firm Shares  Closing Date  shall
       state  that each Share, to be delivered  on that date is duly and validly
       issued, fully  paid,  and  non-assessable,  with  no  personal  liability
       attaching to the ownership thereof, and is not issued in violation of any
       preemptive  rights of  stockholders, and  the Underwriters  have received
       good title  to  the Shares  purchased  by them,  respectively,  from  the
       Selling  Stockholders, as applicable,  for the consideration contemplated
       herein and in good faith and  without notice of any adverse claim  within
       the  meaning of the Uniform Commercial Code, free and clear of any liens,
       security  interests,   pledges,  charges,   encumbrances,   stockholders'
       agreements, voting trusts and other claims.

        (h) All proceedings taken in connection with the sale of the Firm Shares
    and  the Option Shares as herein  contemplated shall be satisfactory in form
    and substance to the Representatives and their counsel, and the Underwriters
    shall have received  from Squadron,  Ellenoff, Plesent &  Sheinfeld, LLP,  a
    favorable  opinion, addressed to the  Representatives and dated such Closing
    Date, with respect to the

                                       14
<PAGE>
    Shares, the  Registration  Statement  and the  Prospectus,  and  such  other
    related  matters,  as the  Representatives may  reasonably request,  and the
    Company and  the  Selling Stockholders  shall  have furnished  to  Squadron,
    Ellenoff,  Plesent & Sheinfeld,  LLP, such documents  as they may reasonably
    request for the purpose of enabling them to pass upon such matters.

    6.  COVENANTS OF THE COMPANY AND THE SELLING STOCKHOLDERS.

    (a) The Company covenants and agrees as follows:

        (i) The Company  shall use its  best efforts to  cause the  Registration
    Statement  to become effective as promptly  as possible. If the Registration
    Statement has become or becomes effective with a form of prospectus omitting
    Rule 430A information,  or filing  of the Prospectus  is otherwise  required
    under Rule 424(b), the Company will file the Prospectus, properly completed,
    pursuant  to Rule 424(b) within the  time period prescribed and will provide
    evidence satisfactory to you of such timely filing. The Company shall notify
    you  immediately,  and  confirm  such  notice  in  writing,  (A)  when   the
    Registration  Statement  and  any  post-effective  amendment  thereto become
    effective, (B) of  the receipt of  any comments from  the Commission or  the
    "blue  sky"  or  securities  authority  of  any  jurisdiction  regarding the
    Registration  Statement,   any   post-effective   amendment   thereto,   the
    Prospectus,  or any amendment or supplement  thereto, and (C) of the receipt
    of any notification with respect to a Stop Order. The Company shall not file
    any amendment to the Registration Statement or supplement to the  Prospectus
    unless the Company has furnished the Representatives a copy for their review
    prior to filing and shall not file any such proposed amendment or supplement
    to  which the Representatives  reasonably object. The  Company shall use its
    best efforts to prevent the  issuance of any Stop  Order and, if issued,  to
    obtain as soon as possible the withdrawal thereof.

        (ii)  During  the  time when  a  prospectus  relating to  the  Shares is
    required to be  delivered hereunder  or under  the Act  or the  Regulations,
    comply  so far as  it is able with  all requirements imposed  upon it by the
    Act, as now existing  and as hereafter amended,  and by the Regulations,  as
    from time to time in force, so far as necessary to permit the continuance of
    sales  of or dealings in the Shares in accordance with the provisions hereof
    and the Prospectus. If, at any time when a prospectus relating to the Shares
    is required to be delivered under the Act and the Regulations, any event  as
    a  result  of which  the Prospectus  as then  amended or  supplemented would
    include any  untrue  statement of  a  material fact  or  omit to  state  any
    material  fact necessary to make the statements  therein in the light of the
    circumstances under which they were made  not misleading, or if it shall  be
    necessary  to amend or supplement  the Prospectus to comply  with the Act or
    the Regulations,  the  Company promptly  shall  prepare and  file  with  the
    Commission,  subject to the third sentence  of paragraph (i) of this Section
    6(a), an  amendment or  supplement  which shall  correct such  statement  or
    omission or an amendment which shall effect such compliance.

       (iii)  The Company shall make generally available to its security holders
    and to the  Representatives as soon  as practicable, but  not later than  45
    days after the end of the 12-month period beginning at the end of the fiscal
    quarter  of the Company during which the  Effective Date (or 90 days if such
    12-month period  coincides  with the  Company's  fiscal year),  an  earnings
    statement (which need not be audited) of the Company, covering such 12-month
    period,  which shall satisfy the  provisions of Section 11(a)  of the Act or
    Rule 158 of the Regulations.

        (iv) The Company shall  furnish to the  Representatives and counsel  for
    the   Underwriters,  without  charge,  signed  copies  of  the  Registration
    Statement  (including  all  exhibits  thereto,  Incorporated  Documents  and
    amendments thereto) and to each other Underwriter a copy of the Registration
    Statement  (without  exhibits  thereto or  Incorporated  Documents)  and all
    amendments  thereof  and,  so  long  as  delivery  of  a  prospectus  by  an
    Underwriter or dealer may be required by the Act or the Regulations, as many
    copies  of any preliminary prospectus and  the Prospectus and any amendments
    thereof and  supplements  thereto  as  the  Representatives  may  reasonably
    request.

        (v)  The  Company shall  cooperate  with the  Representatives  and their
    counsel in endeavoring to  qualify the Shares for  offer and sale under  the
    laws of such jurisdictions as the Representatives may

                                       15
<PAGE>
    designate  and  shall  maintain such  qualifications  in effect  so  long as
    required for the  distribution of  the Shares; provided,  however, that  the
    Company  shall  not  be required  in  connection therewith,  as  a condition
    thereof, to qualify as a foreign corporation or to execute a general consent
    to service of process in any  jurisdiction or subject itself to taxation  as
    doing business in any jurisdiction.

        (vi)  For a period of  five years after the  date of this Agreement, the
    Company shall  supply to  each of  the Representatives,  and to  each  other
    Underwriter  who  may  so  request  in  writing,  copies  of  such financial
    statements and other periodic  and special reports as  the Company may  from
    time to time distribute generally to the holders of any class of its capital
    stock and to furnish to each of the Representatives a copy of each annual or
    other report it shall be required to file with the Commission.

       (vii)  Without the  prior written consent  of the  Representatives, for a
    period of 180 days from  the date on which a  public offering of the  Shares
    commences, the Company shall not issue, sell or register with the Commission
    or  otherwise  dispose of,  directly or  indirectly,  any securities  of the
    Company (or any securities convertible  into or exercisable or  exchangeable
    for  securities  of the  Company),  except for  the  issuance of  the Shares
    pursuant to the Registration Statement.

      (viii) On or before  completion of this offering,  the Company shall  make
    all  filings required  under applicable  securities laws  and by  the NASDAQ
    National Market.

        (ix) Until the expiration of three years from the Closing Date, or  such
    later  date as the Company and Rodman & Renshaw, Inc. may agree, if Rodman &
    Renshaw, Inc., individually and not as a Representative of the Underwriters,
    shall so indicate in writing to the Company, the Company shall use its  best
    efforts  to  cause an  individual selected  from  time to  time by  Rodman &
    Renshaw, Inc. to  be elected  as a director  of the  Company. Such  director
    shall  be  entitled  to  receive reimbursement  for  expenses  and  shall be
    compensated in the same manner as the other directors of the Company. Rodman
    & Renshaw, Inc. and such director shall be indemnified to the same extent as
    the other directors of the Company.

        (x) Prior to each Closing Date and  for a period of 25 days  thereafter,
    you  shall be given reasonable written prior  notice of any press release or
    other direct  or indirect  communication and  of any  press conference  with
    respect  to the  Company, the  financial conditions,  results of operations,
    business, properties, assets, liabilities of the Company, or this offering.

    (b) The Company agrees to pay, or reimburse if paid by the  Representatives,
whether  or not  the transactions  contemplated hereby  are consummated  or this
Agreement is terminated, all costs and expenses relating to the registration and
public offering of the Shares including those relating to: (i) the  preparation,
printing,  filing and distribution  of the Registration  Statement including all
exhibits thereto, each  preliminary prospectus, the  Prospectus, all  amendments
and  supplements  to  the Registration  Statement  and the  Prospectus,  and any
documents required  to  be delivered  with  any Preliminary  Prospectus  or  the
Prospectus,  and the  printing, filing and  distribution of  the Agreement Among
Underwriters, this Agreement  and related  documents; (ii)  the preparation  and
delivery  of  certificates  for  the  Shares  to  the  Underwriters;  (iii)  the
registration or  qualification  of the  Shares  for  offer and  sale  under  the
securities  or Blue Sky laws of the various jurisdictions referred to in Section
6(a)(v), including the fees and disbursements of counsel for the Underwriters in
connection  with  such  registration  and  qualification  and  the  preparation,
printing,  distribution and shipment  of preliminary and  supplementary Blue Sky
memoranda; (iv) the furnishing (including costs of shipping and mailing) to  the
Representatives   and  to  the  Underwriters   of  copies  of  each  preliminary
prospectus, the Prospectus and all amendments or supplements to the  Prospectus,
and of the several documents required by this Section to be so furnished, as may
be  reasonably requested for use in connection with the offering and sale of the
Shares by the Underwriters  or by dealers  to whom Shares may  be sold; (v)  the
filing  fees  of  the  National  Association  of  Securities  Dealers,  Inc.  in
connection with  its  review of  the  terms of  the  public offering;  (vi)  the
furnishing  (including costs of shipping and mailing) to the Representatives and
to the Underwriters of copies of all reports and information required by Section
6(a)(vi); (vii) inclusion  of the Shares  for quotation on  the NASDAQ  National
Market  System; and (viii) all transfer taxes,  if any, with respect to the sale
and delivery of the  Shares by the  Company and the  Selling Stockholder to  the
Underwriters.  Except  as  otherwise  contemplated  by  Section  9  hereof,  the
Underwriters will pay  their own  counsel fees and  expenses to  the extent  not
otherwise   covered  by   clause  (iii)   above,  and   their  own   travel  and

                                       16
<PAGE>
travel-related expenses  in  connection with  the  distribution of  the  Shares.
Without  limiting  the  Company's  obligations  set  forth  above,  the  Selling
Stockholders agree to pay all  of the other costs  and expenses incident to  the
performance  of its obligations under this Agreement  and the sale of the Shares
by them hereunder.

    7.  INDEMNIFICATION.

    (a) The Company agrees to indemnify  and hold harmless each Underwriter  and
each  person, if any, who controls any Underwriter within the meaning of Section
15 of the  Act or Section  20 of the  Exchange Act against  any and all  losses,
claims,  damages  and liabilities,  joint or  several (including  any reasonable
investigation, legal and  other expenses  incurred in connection  with, and  any
amount  paid  in settlement  of, any  action,  suit or  proceeding or  any claim
asserted), to which they, or any of them, may become subject under the Act,  the
Exchange  Act or  other Federal  or state  law or  regulation, at  common law or
otherwise, insofar as such losses, claims,  damages or liabilities arise out  of
or  are based  upon (i) any  untrue statement  or alleged untrue  statement of a
material  fact  contained  in  any  preliminary  prospectus,  the   Registration
Statement  or the Prospectus or any  amendment thereof or supplement thereto, or
arise out of or are based upon any omission or alleged omission to state therein
such fact required  to be stated  therein or necessary  to make such  statements
therein not misleading, or (ii) the merger of Aurora Environmental Inc. with and
into  the Company, including for such  purposes, any untrue statement or alleged
untrue statement  of  a  material  fact contained  in  any  proxy  statement  or
registration  statement  related to  such merger,  or  any amendment  thereof as
supplement thereto, or arise out  of or are based  upon any omission or  alleged
omission  to state therein such fact required  to be stated therein or necessary
to make such statements therein not misleading. The Selling Stockholders  agree,
jointly  and not  severally, to indemnify  each Underwriter and  each person, if
any, who controls any Underwriter within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, against any and all losses, claims, damages  and
liabilities, joint or several (including any reasonable investigation, legal and
other  expenses incurred in  connection with, and any  amount paid in settlement
of, any action, suit or proceeding or any claim asserted), to which they, or any
of them, may become subject under the Act, the Exchange Act or other Federal  or
state  law or regulation,  at common law  or otherwise, insofar  as such losses,
claims, damages  or  liabilities arise  out  of or  are  based upon  any  untrue
statement  or alleged untrue statement  of a material fact  with respect to such
Selling Stockholders contained in  any preliminary prospectus, the  Registration
Statement  or  the Prospectus  or any  amendment  thereof or  supplement thereto
(which amendments or supplements are furnished to such Selling Stockholders), or
which arise out of or are based  upon any omission or alleged omission to  state
therein  such  fact required  to be  stated  therein or  necessary to  make such
statements therein  not  misleading,  but only  with  reference  to  information
relating  to such Selling Stockholders furnished in writing to the Company by or
on behalf of such Selling Stockholders expressly for use in connection with  the
preparation  of  the  Registration  Statement and  Prospectus  or  any amendment
thereof or supplement thereto. Such indemnity shall not inure to the benefit  of
any  Underwriter (or any person controlling  such Underwriter) on account of any
losses, claims, damages or  liabilities arising from the  sale of the Shares  to
any  person by such Underwriter if such  untrue statement or omission or alleged
untrue statement  or  omission was  made  in such  preliminary  prospectus,  the
Registration  Statement or the  Prospectus, or such  amendment or supplement, in
reliance upon and  in conformity with  information furnished in  writing to  the
Company by the Representatives on behalf of any Underwriter specifically for use
therein.  The obligations of the Selling  Stockholders, pursuant to this Section
7(a) and Section 8, shall be limited  to an amount not exceeding the product  of
the  Per Share Price to Public  of the Shares as set  forth on the cover page of
the Prospectus and the number of Shares being sold by each of them. In no  event
shall  the indemnification agreement contained in this Section 7(a) inure to the
benefit  of  any  Underwriter  on  account  of  any  losses,  claims,   damages,
liabilities  or actions  arising from  the sale  of the  Shares upon  the public
offering to any  person by  such Underwriter  if such  losses, claims,  damages,
liabilities  or actions arise out of, or are based upon, a statement or omission
or alleged  omission in  a preliminary  prospectus and  if, in  respect to  such
statement,  omission or alleged  omission, the Prospectus  differs in a material
respect from such preliminary  prospectus and a copy  of the Prospectus has  not
been  sent or given to such person at  or prior to the confirmation of such sale
to such person. This  indemnity agreement will be  in addition to any  liability
which the Company and the Selling Stockholders may otherwise have.

                                       17
<PAGE>
    (b)  Each Underwriter  agrees, severally and  not jointly,  to indemnify and
hold harmless the Company, each person, if any, who controls the Company  within
the  meaning of Section  15 of the Act  or Section 20 of  the Exchange Act, each
director of  the  Company,  and  each  officer of  the  Company  who  signs  the
Registration  Statement and the Selling Stockholders,  to the same extent as the
foregoing indemnity  from  the Company  and  the Selling  Stockholders  to  each
Underwriter,  but only  insofar as such  losses, claims,  damages or liabilities
arise out of  or are  based upon  any untrue  statement or  omission or  alleged
untrue  statement or omission which was  made in any Preliminary Prospectus, any
Rule 430A  Prospectus, the  Registration  Statement or  the Prospectus,  or  any
amendment thereof or supplement thereto, which were made in reliance upon and in
conformity  with  information  furnished  in  writing  to  the  Company  by  the
Representatives on behalf of any Underwriter for specific use therein; provided,
however, that  the  obligation of  each  Underwriter to  indemnify  the  Company
(including  any controlling person, director or officer thereof) and the Selling
Stockholders shall be limited  to the net proceeds  received by the Company  and
the  Selling Stockholders, respectively, from such Underwriter. For all purposes
of this Agreement,  the amounts of  the selling concession  and reallowance  set
forth  in the Prospectus constitute the only information furnished in writing by
or on  behalf of  any Underwriter  expressly for  inclusion in  any  Preliminary
Prospectus,  any  Rule  430A  Prospectus,  the  Registration  Statement  or  the
Prospectus or any amendment or supplement thereto.

    (c) Any party that proposes to assert the right to be indemnified under this
Section will, promptly after  receipt of notice of  commencement of any  action,
suit  or proceeding against such party in respect of which a claim is to be made
against an indemnifying party  or parties under this  Section, notify each  such
indemnifying  party  of the  commencement of  such  action, suit  or proceeding,
enclosing a  copy of  all  papers served.  No  indemnification provided  for  in
Section  7(a) or  7(b) shall be  available to any  party who shall  fail to give
notice as provided  in this Section  7(c) if the  party to whom  notice was  not
given  was unaware of the proceeding to which such notice would have related and
was prejudiced by the failure to give such notice but the omission so to  notify
such indemnifying party of any such action, suit or proceeding shall not relieve
it from any liability that it may have to any indemnified party for contribution
or  otherwise  than  under  this  Section. In  case  any  such  action,  suit or
proceeding shall be brought  against any indemnified party  and it shall  notify
the indemnifying party of the commencement thereof, the indemnifying party shall
be  entitled to participate in,  and, to the extent  that it shall wish, jointly
with any  other indemnifying  party similarly  notified, to  assume the  defense
thereof,  with counsel  reasonably satisfactory  to such  indemnified party, and
after notice  from the  indemnifying  party to  such  indemnified party  of  its
election  so to assume the  defense thereof and the  approval by the indemnified
party of  such counsel,  the indemnifying  party  shall not  be liable  to  such
indemnified  party for any legal or other expenses, except as provided below and
except for the reasonable costs  of investigation subsequently incurred by  such
indemnified  party in connection with the defense thereof. The indemnified party
shall have the right to employ its counsel in any such action, but the fees  and
expenses  of such  counsel shall  be at  the expense  of such  indemnified party
unless (i)  the  employment  of  counsel by  such  indemnified  party  has  been
authorized  in writing by  the indemnifying parties,  (ii) the indemnified party
shall have reasonably concluded that there may be a conflict of interest between
the indemnifying parties and the indemnified party in the conduct of the defense
of such action (in which case the indemnifying parties shall not have the  right
to  direct the defense  of such action  on behalf of  the indemnified party), or
(iii) the indemnifying  parties shall not  have employed counsel  to assume  the
defense of such action within a reasonable time after notice of the commencement
thereof,  in each  of which  cases the reasonable  fees and  expenses of counsel
shall be at the expense of the indemnifying parties. An indemnifying party shall
not be  liable for  any settlement  of  any action,  suit, proceeding  or  claim
effected without its written consent.

    8.   CONTRIBUTION.  In order to  provide for just and equitable contribution
in circumstances in which the indemnification provided for in Sections 7(a)  and
(b)  is  due in  accordance with  its terms  but for  any reason  is held  to be
unavailable from the Company, the Selling Stockholders or the Underwriters,  the
Company,  the Selling Stockholders and the  Underwriters shall contribute to the
aggregate losses, claims, damages and liabilities (including any  investigation,
legal  and other expenses reasonably incurred in connection with, and any amount
paid in settlement of,  any action, suit or  proceeding or any claims  asserted,
but  after deducting any contribution received by the Company from persons other
than the Underwriters, such as the Selling Stockholders, persons who control the
Company  within  the  meaning   of  the  Act,  officers   of  the  Company   who

                                       18
<PAGE>
signed  the Registration Statement and directors of the Company, who may also be
liable for contribution) to which the  Company and the Selling Stockholders  and
one  or  more  of the  Underwriters  may be  subject  in such  proportion  as is
appropriate to reflect  the relative benefits  received by the  Company and  the
Selling  Stockholders on the one hand and the Underwriters on the other from the
offering of the Shares or, if such allocation is not permitted by applicable law
or indemnification is not  available as a result  of the indemnifying party  not
having received notice as provided in Section 7 hereof, in such proportion as is
appropriate to reflect not only the relative benefits referred to above but also
the  relative fault of the Company and  the Selling Stockholders on the one hand
and the Underwriters on the other in connection with the statements or omissions
which resulted in such losses, claims, damages, liabilities or expenses, as well
as any other relevant equitable  considerations. The relative benefits  received
by the Company, the Selling Stockholders and the Underwriters shall be deemed to
be  in the same proportion  as (x) the total proceeds  from the Offering (net of
underwriting discounts but before deducting expenses) received by the Company or
the Selling Stockholders from the sale of the Shares, as set forth in the  table
on  the cover page of the Prospectus (but not taking into account the use of the
proceeds of such sale of  Shares by the Company),  bear to (y) the  underwriting
discount  received by the Underwriters,  as set forth in  the table on the cover
page of  the  Prospectus.  The  relative  fault  of  the  Company,  the  Selling
Stockholders  and the  Underwriters shall be  determined by  reference to, among
other things, whether the untrue or alleged untrue statement of a material  fact
related  to information supplied by the Company, the Selling Stockholders or the
Underwriters and the parties' relative intent, knowledge, access to  information
and  opportunity to correct or prevent  such statement or omission. The Company,
the Selling Stockholders and  the Underwriters agree that  it would not be  just
and  equitable if contribution pursuant to this Section 8 were determined by pro
rata allocation (even if  the Underwriters were treated  as one entity for  such
purpose) or by any other method of allocation which does not take account of the
equitable  considerations referred  to above. Notwithstanding  the provisions of
this Section 8, (i) in no case shall any Underwriter (except as may be  provided
in  the Agreement Among Underwriters) be liable or responsible for any amount in
excess of the underwriting discount applicable  to the Shares purchased by  such
Underwriter  hereunder, (ii) in no case shall any of the Selling Stockholders be
liable or responsible for any amount in  excess of the product of the Per  Share
Price  to Public of the Shares as set  forth on the cover page of the Prospectus
and the number of Shares  being sold by each of  them subject to the  limitation
expressed in Section 7(a), and (iii) the Company shall be liable and responsible
for any amount in excess of the underwriting discount and the amount referred to
in  clause  (ii); provided,  however  (i) that  no  person guilty  of fraudulent
misrepresentation (within the  meaning of  Section 11(f)  of the  Act) shall  be
entitled  to contribution from any person who  was not guilty of such fraudulent
misrepresentation. For purposes  of this  Section 8,  each person,  if any,  who
controls  an Underwriter within the meaning of  Section 15 of the Act or Section
20(a) of the Exchange  Act shall have  the same rights  to contribution as  such
Underwriter,  and  each person,  if  any, who  controls  the Company  within the
meaning of the Section 15 of the Act or Section 20(a) of the Exchange Act,  each
officer of the Company who shall have signed the Registration Statement and each
director  of  the Company  shall have  the  same rights  to contribution  as the
Company, subject in each case to clauses (i), (ii) and (iii) in the  immediately
preceding  sentence of this Section 8.  Any party entitled to contribution will,
promptly after  receipt  of  notice  of commencement  of  any  action,  suit  or
proceeding  against such party in respect of  which a claim for contribution may
be made against another party or  parties under this Section, notify such  party
or  parties from whom contribution may be  sought, but the omission so to notify
such party or parties from whom contribution may be sought shall not relieve the
party or parties from whom contribution may be sought from any other  obligation
it  or they may  have hereunder or  otherwise than under  this Section. No party
shall be liable for contribution with respect to any action, suit, proceeding or
claim settled  without its  written consent.  The Underwriters'  obligations  to
contribute  pursuant  to  this Section  8  are  several in  proportion  to their
respective underwriting commitments and not joint.

    9.   TERMINATION.   This Agreement  may be  terminated with  respect to  the
Shares  to be purchased on any Closing  Date by the Representatives by notifying
the Company at any time prior to the purchase of the Shares:

        (a) in the absolute discretion of  the Representatives at or before  any
    Closing Date: (i) if on or prior to such date, any domestic or international
    event  or act or occurrence  has materially disrupted, or  in the opinion of
    the Representatives will  in the future  materially disrupt, the  securities
    markets; (ii) if

                                       19
<PAGE>
    there has occurred any new outbreak or material escalation of hostilities or
    other calamity or crisis the effect of which on the financial markets of the
    United States is such as to make it, in the judgment of the Representatives,
    inadvisable  to proceed with  the Offering; (iii)  if there shall  be such a
    material  adverse  change  in  general  financial,  political  or   economic
    conditions  or  the  effect  of international  conditions  on  the financial
    markets in the  United States such  as to make  it, in the  judgment of  the
    Representatives,  inadvisable or impracticable to market the Shares; (iv) if
    trading in  the Shares  has  been suspended  by  the Commission  or  trading
    generally on the New York Stock Exchange, Inc., the American Stock Exchange,
    Inc. or the NASDAQ National Market has been suspended or limited, or minimum
    or  maximum  ranges for  prices  for securities  shall  have been  fixed, or
    maximum ranges  for  prices  for  securities have  been  required,  by  said
    exchanges  or  by  order  of the  Commission,  the  National  Association of
    Securities Dealers, Inc., or any other governmental or regulatory authority;
    or (v) if a  banking moratorium has  been declared by  any state or  federal
    authority, or

        (b) at or before any Closing Date, if any of the conditions specified in
    Section  5  shall not  have  been fulfilled  when  and as  required  by this
    Agreement.

    If this Agreement is terminated pursuant  to any of its provisions,  neither
the  Company nor the  Selling Stockholders shall  be under any  liability to any
Underwriter, and no Underwriter shall be  under any liability to the Company  or
the Selling Stockholders, except that (y) if this Agreement is terminated by the
Representatives or the Underwriters because of any failure, refusal or inability
on  the part of the Company or the Selling Stockholders or all of them to comply
with the  terms or  to fulfill  any of  the conditions  of this  Agreement,  the
Company  and the  Selling Stockholders will  reimburse the  Underwriters for all
out-of-pocket expenses (including the fees  and disbursements of their  counsel)
incurred by them in connection with the proposed purchase and sale of the Shares
or  in  contemplation  of  performing their  obligations  hereunder  and  (z) no
Underwriter who shall have failed or refused to purchase the Shares agreed to be
purchased by it under this  Agreement, without some reason sufficient  hereunder
to  justify cancellation or termination of its obligations under this Agreement,
shall be relieved of liability to the Company and the Selling Stockholders or to
the other Underwriters for damages occasioned by its failure or refusal.

    10.  SUBSTITUTION OF UNDERWRITERS.  If one or more of the Underwriters shall
fail (other  than  for  a  reason sufficient  to  justify  the  cancellation  or
termination  of this Agreement under Section 9)  to purchase on any Closing Date
the Shares agreed to be  purchased on such Closing  Date by such Underwriter  or
Underwriters,  the Representatives may find  one or more substitute underwriters
to purchase such Shares or make  such other arrangements as the  Representatives
may  deem advisable or  one or more  of the remaining  Underwriters may agree to
purchase  such  Shares  in   such  proportions  as  may   be  approved  by   the
Representatives,  in each case upon the terms set forth in this Agreement. If no
such arrangements have been made  by the close of  business on the business  day
following such Closing Date:

        (a)  if  the  number  of  Shares  to  be  purchased  by  the  defaulting
    Underwriters on such Closing  Date shall not exceed  10% of the Shares  that
    all  the Underwriters are  obligated to purchase on  such Closing Date, then
    each of the nondefaulting Underwriters  shall be obligated to purchase  such
    Shares  on  the terms  herein set  forth in  proportion to  their respective
    obligations hereunder; provided, that in  no event shall the maximum  number
    of  Shares that any Underwriter has agreed to purchase pursuant to Section 1
    be increased pursuant  to this  Section 10 by  more than  one-ninth of  such
    number of Shares without the written consent of such Underwriter, or

        (b)  if  the  number  of  Shares  to  be  purchased  by  the  defaulting
    Underwriters on such Closing  Date shall exceed 10%  of the Shares that  all
    the  Underwriters are obligated  to purchase on such  Closing Date, then the
    Company shall be entitled to an additional business day within which it may,
    but is not obligated to, find one or more substitute underwriters reasonably
    satisfactory to the Representatives to  purchase such Shares upon the  terms
    set forth in this Agreement.

    In  any such case, either the Representatives  or the Company shall have the
right to postpone the applicable Closing Date for a period of not more than five
business days in order  that necessary changes  and arrangements (including  any
necessary amendments or supplements to the Registration Statement or Prospectus)
