                                     PART I

Item 1.       BUSINESS

EMCON (referred to herein as "EMCON" and the "Company")  provides  comprehensive
environmental engineering, design, construction, operations and maintenance, and
equipment fabrication services to a variety of public and private clients. EMCON
is a leader in the design,  construction  and remediation of solid and hazardous
waste  transfer,  storage and disposal  facilities,  having  participated in the
design,  construction  and remediation of several hundred such facilities in the
United  States,  as well as  Argentina,  Canada,  Hong  Kong,  Mexico,  Peru and
Venezuela.   EMCON's  waste  facility   services   include  site  selection  and
evaluation,  facility design,  development of preprocessing and operating plans,
assistance in regulatory  compliance  and  permitting,  final  closure,  end-use
planning and design, construction, and operations and maintenance. The Company's
services also include the  development  of programs  dealing with  environmental
assessments and remediation of contaminated  sites, as well as services  related
to applied sciences such as fuel spill damage assessment, marine fate-and-effect
studies and natural resource damage assessment. The Company's professional staff
includes chemical, civil, geotechnical, mechanical, electrical and environmental
engineers; marine and terrestrial biologists;  oceanographers; plant ecologists;
chemists;   geologists;   hydrogeologists;   hydrologists   and   toxicologists.
References  to the  Company  and  EMCON in this  report  include  the  Company's
subsidiaries, unless the context indicates otherwise.

On February  29,  1996,  EMCON  acquired all the  outstanding  capital  stock of
Organic  Waste  Technologies,  Inc.  ("OWT"),  a  Cleveland-based  construction,
equipment and operations and maintenance  company with significant  expertise in
solid  waste  management.  OWT was  subsequently  integrated  into  and is now a
significant component of the Company's Operation and Construction  Division. The
Company  purchased OWT for  $13,859,000 in cash plus the issuance of convertible
notes and other contractual  obligations to pay certain senior OWT management in
the aggregate  principal amount of $1,747,000.  The notes and other  contractual
obligations  to pay bear  interest  payable at the rate of 8% per annum with all
principal due and payable in full on March 1, 2001. The above obligations may be
converted into shares of OWT common stock upon an  underwritten  public offering
of OWT's  common stock in an amount in excess of  $10,000,000.  In the event the
notes have not been converted into OWT shares they may instead be converted into
shares of EMCON  common  stock for a period of ninety  days after  November  30,
2001, at a conversion price of $6.50 per share.

The Company, through its wholly owned subsidiary,  Columbia Analytical Services,
Inc.  ("CAS"),  also operates a full-service,  integrated  network of analytical
laboratories in Alaska, Arizona,  California,  Florida, New York and Washington.
On December 31, 1996,  the Company  signed a Letter of Intent to sell CAS to the
CAS employees  for cash,  notes and other  consideration  valued,  in total,  at
approximately  $7.5  million.  The sale is expected to close prior to the end of
the first quarter of 1997. In anticipation  of the sale, the Company  recognized
an impairment in its investment in CAS of $3,327,000; including, a write-down in
the carrying value of goodwill associated with previous laboratory  acquisitions
of $1,426,000.

On December  31,  1996,  the  Company  completed  the sale of its Yolo  landfill
gas-to-energy  project in return for a one-time cash payment in January, 1997 of
$800,000. The Company incurred a loss in 1996 of $88,000 on the sale.






                                       4



On March  6,  1997,  the  Company  completed  the  sale of its  Marina  landfill
gas-to-energy  project for a net up front cash payment of $800,000.  The Company
is eligible to receive an additional $200,000 prior to December 31, 1997 subject
to certain post-closing  contingencies - specifically,  that no material adverse
changes are made to the provisions of Section 29 of the Internal Revenue Code of
1986, as amended, pertaining to the availability of unconventional fuel credits.

                                    Services

Following  the  sale of CAS,  the  Company  will be  comprised  of two  distinct
operating divisions:  the Professional  Services Division (formerly known as the
Consulting Division);  and the Operations and Construction Division.

                              Solid Waste Services

The Company's  Professional  Services  Division and Operations and  Construction
Division  offer a full range of services  to  operators  of solid and  hazardous
waste transfer,  storage,  recycling, and disposal facilities;  from the design,
permitting  and  construction  of the  facility,  to the  provision of necessary
equipment and components,  to post-closure,  operations and maintenance services
and end-use  planning.  Customers may utilize the full range or a portion of the
Company's services.

Through its  extensive  experience  in  disposal  site  design,  the Company has
developed expertise in three critical areas of waste disposal technology - liner
systems,  leachate  treatment,  and gas  control/recovery  systems.  To  protect
surrounding soil and water, natural and synthetic liners are used to collect and
contain  potentially  hazardous liquids  percolating through the waste that have
been  deposited  at the site  ("leachate").  Leachate is then  collected  on the
surface of the liner,  withdrawn  from the landfill and treated using  physical,
chemical,  evaporative  and/or  biological  methods.  Gas control  and  recovery
systems,  which may be  installed  on active  or closed  landfills,  are used to
control  the  methane  gas  produced  by  decomposing   organic  refuse.   Where
economical,  recovery  systems are designed to extract  methane to generate heat
and/or  electricity,  or in some cases to evaporate leachate using the Company's
patented leachate  evaporation system.  Federal regulation now requires that all
new land disposal  facilities  utilize liners and methane control  systems,  and
that these systems be required to meet increasingly stringent design standards.

EMCON's  services to its clients  often begin with the  evaluation  of potential
disposal  facility sites.  The  hydrogeological  and  geotechnical  staff of the
Professional  Services  Division  evaluate  soils,  groundwater  occurrence  and
quality,  seismic stability and potential flooding at possible locations,  while
other professionals analyze operational  considerations,  such as proximity of a
site  to  water  sources,  visibility  to the  public  and  estimated  operating
expenses. Once desirable sites are identified,  the Company assists in obtaining
regulatory  approvals  by  drafting  environmental  impact  reports  and  permit
applications, appearing at hearings and negotiating with government agencies.

EMCON performs detailed cost/benefit analyses of design alternatives,  using, if
possible,  natural  features of the site to reduce cost.  EMCON engineers design
the waste disposal facility, considering such factors as the volume and types of
material  to be  disposed  at the site,  land use and  public  policy,  physical
characteristics  of the site and regulatory  requirements.  EMCON identifies the
type of natural or synthetic  liners which are  appropriate  or required for the
site and designs  the  monitoring  systems,  landfill  gas  control  systems and
leachate  recovery and  treatment  systems.  EMCON also  monitors  statutory and
regulatory  developments,  and assists operators in implementing required design
or  operating  changes  and  preparing   additional   permit   applications  and
environmental reports.

                                       5


Throughout the construction process, the Professional Services Division performs
services  such  as  preparing  detailed  construction  documents,  assisting  in
contractor  selection,  scheduling and monitoring  work in progress,  performing
construction quality assurance review, review of contractor requests for payment
and assisting with regulatory compliance and permitting. The Company also trains
disposal facility personnel,  performs  environmental  monitoring services,  and
designs site maintenance programs and operating plans.

Where appropriate,  the Operations and Construction Division can perform a broad
range of related services,  including  construction of landfill cells,  landfill
remediation and collection systems, landfill gas flares and control systems, and
leachate  evaporation systems, as well as the capping,  closure,  development of
landfill gas recovery projects,  and long-term  operation and maintenance of old
landfills.

The Operations and  Construction  Division is complimented  by ET  Environmental
Corporation  ("ET"),  a  50/50  joint  venture  between  EMCON  and  The  Turner
Construction   Company   ("Turner").   ET's  charter  is  to  provide  primarily
above-ground  environmental,  remedial and  construction  services on a national
basis,  utilizing the regional  resources of EMCON and Turner. ET is a leader in
the development and construction of solid waste transfer  stations and materials
recovery facilities on a design build basis.

                            Site Restoration Services

EMCON's  environmental  expertise  incorporates  analytical and  risk-assessment
capabilities enabling remediation  specialists to design site-specific solutions
to environmental  compliance and  contamination  problems.  The Company is often
called upon to design and monitor  remediation  plans when corrective  action is
required  at solid or  hazardous  waste  storage or disposal  facilities  and at
commercial or industrial  plant sites.  Problems  which may require  remediation
include  leaching of  hazardous  chemicals  or wastes into  groundwater,  ground
instability  or erosion,  flooding and migration of landfill gas. Work generally
entails  site  reconnaissance,   drilling  exploratory  borings,  and  soil  and
groundwater sampling as part of the assessment program.  Using data collected in
the  assessment  phase of a project,  the  Company  then  defines the nature and
extent  of  the  problem,  develops  a  remediation  program  and  monitors  its
implementation.

The Company generally  approaches such projects by consulting with the client on
the nature and scope of the problem.  Historical  information about the site, if
available,  is reviewed to determine  the most likely  sources and  locations of
contamination.  Information  about the local  geology and  hydrogeology  is also
reviewed to determine potential migration pathways. A detailed work plan is then
prepared  that  describes  the  field  investigation  program  to be  conducted,
including  the number and location of samples to be  collected  and the specific
chemical  analyses to be  performed.  Trained  personnel  then conduct the field
investigation  program,  which may include  drilling  soil  borings,  installing
groundwater  monitoring  wells,  and  collecting  samples of soil,  groundwater,
surface water and/or industrial discharges.

Following laboratory analysis of the various samples collected,  the results are
evaluated by Company engineers and scientists to determine the nature and extent
of contamination at the site.  Depending on the complexity of the site, this may
require more than one round of sampling. Site cleanup levels are then determined
based on the media that have been impacted,  the  contaminants  of concern,  the
intended use of the property, and state and federal regulations. In consultation
with the  client,  various  remediation  alternatives  are then  identified  and
evaluated for  implementability,  effectiveness,  permanence and cost.  Remedial


                                       6


alternatives  at a site may include the excavation and removal of the sources of
contamination  and  contaminated  soil, the removal and treatment of groundwater
using physical and chemical  treatment  systems,  or the installation of surface
caps and vertical hydraulic barriers.  EMCON also applies in-situ  technologies,
such  as  vapor  extraction  or  bioremediation  as  appropriate,  to  remediate
contaminated  soils  and  ground-water  as a means to reduce  cost and  minimize
disturbance. To assure continued compliance during and after remediation,  EMCON
designs  and  provides   operations  and   maintenance   programs  for  affected
facilities.

Through its ET joint venture with Turner,  the Company is also able to provide a
complete turnkey package to clients,  combining  planning and  implementation of
facility/plant   decommissioning;    remediation   of   soil   and   groundwater
contamination, and lead based paint and asbestos abatement.

                                In-Plant Services

In the last several years the market has seen a significant  trend among many of
the larger  industrial  clients to outsourcing many of their  environmental  and
health and safety compliance requirements. EMCON offers responsive assistance to
the  regulated  community  in a broad  range  of  areas  including  air  quality
regulatory   compliance   through  provision  of  air  quality   assessment  and
engineering  services.  Company  personnel have direct experience in air quality
permitting  under  the  New  Source  Review  (NSR),  Prevention  of  Significant
Deterioration (PSD) and added requirements under the Clean Air Act Amendments of
1990,  preparing  emission  inventories (for criteria and toxic air pollutants),
performing  risk  assessment to evaluate  potential  human and ecological  risk,
evaluating  emission  control  technologies  (BACT/RACT/LAER/MACT),   dispersion
modeling,  ambient  air  quality  and  meteorological  measurements,   pollution
prevention and waste  minimization,  indoor air,  litigation  support and expert
testimony, and compliance audits. EMCON's air quality staff are fully integrated
with  staff  in  other  environmental  disciplines  to  provide  cost  effective
evaluations and compliance  solutions to situations which involve multiple media
contamination.  In addition,  EMCON provides OSHA required  environmental health
and safety training to its clients and other EMCON subsidiaries.

                         Analytical Laboratory Services

Columbia  Analytical  Services,  Inc.  (CAS),  EMCON's  wholly-owned  laboratory
subsidiary,  provides a broad spectrum of analytical services for its clients in
industry  and  government.   Industrial  accounts  include  aerospace,  defense,
electronics,  petroleum, pulp and paper, and waste disposal. CAS is comprised of
a network of analytical laboratories  headquartered in Kelso,  Washington,  with
branches  in  Anchorage,  Alaska;  Phoenix,  Arizona;  Canoga Park and San Jose,
California;  Jacksonville,  Florida; Tuxedo, New York, and Bothell,  Washington.
CAS also  operates  a number of  mobile  laboratories.  With a highly  qualified
staff, a rigorous quality assurance  program,  and  state-of-the-art  analytical
testing equipment,  CAS implements a rigorous quality assurance  program,  which
with  its   state-of-the-art   equipment,   permits  the   provision  of  timely
cost-effective  services  tailored  to the  individual  needs  of  its  clients.
Approximately  25% of CAS  revenues  have been  generated  from  within  EMCON's
Professional Services Division.

In addition to  participation  in the US EPA Water  Pollution  and Water  Supply
programs,  CAS  performs  work for the  Department  of  Defense  under  programs
sponsored by the U.S. Army Corps of Engineers and the U.S.  Navy.  CAS currently
holds  or  has  pending  certifications/accreditations  in a  number  of  states
including Alaska, Arizona, California, Florida, Idaho, Massachusetts,  New York,
Oregon,  Utah  and  Washington.   Other  accreditations   include  the  American
Association  of  Laboratory  Accreditations  (A2LA) and the American  Industrial
Hygiene Associations (AIHA).

                                       7


On December 31, 1996,  the Company  signed a Letter of Intent to sell CAS to the
CAS employees  for cash,  notes and other  consideration  valued,  in total,  at
approximately  $7.5  million.  The sale is expected to close prior to the end of
the first quarter of 1997. In anticipation  of the sale, the Company  recognized
an impairment in its investment in CAS of $3,327,000;  including a write-down in
the carrying value of goodwill associated with previous laboratory  acquisitions
of $1,426,000.

                              Clients and Marketing

EMCON's  principal clients are industrial  concerns,  predominantly in the waste
disposal,  petroleum, wood products, chemicals and manufacturing industries. The
Company also provides services to utilities, non-regulatory government entities,
and financial  institutions.  No single  client  accounts for 10% or more of the
Company's net revenue.  The Company often enters into master service  agreements
with major clients, which set forth the general terms and conditions under which
EMCON will perform services and which  facilitate  repeated use of the Company's
services.

EMCON focuses significant efforts on providing high quality services in a timely
manner and developing long-term relationships with its clients. EMCON assigns an
experienced project manager to each project to coordinate work undertaken by the
numerous  professionals  from  different  disciplines  within the Company.  This
approach  reduces the time and cost  required to complete a project and relieves
the client of the  responsibility  of  coordinating  the efforts of  independent
consultants.  Because  the  Company  provides a broad  range of  services,  work
performed  for a  client  in one  technical  area  often  leads to work in other
technical areas.

In the last  several  years,  an  increasing  amount  of work has been done on a
competitive  bid basis in response to client  requests for  proposals.  This has
required the dedication of significantly  greater  resources to proposal writing
and  general  business  development,  and the  implementation  of a more  formal
marketing program to share leads and coordinate resources nationwide.

To further  promote its  services,  the Company takes an active role in industry
trade associations to enhance its national  reputation for technical  expertise.
Similarly, EMCON provides services to a wide variety of local, state and federal
government  agencies and  contractors.  Participation  in such contracts  allows
EMCON to remain on the leading  edge of new  technological  developments  and to
publicize its expertise.

                                   Regulation

Public  concern over health,  safety and  preservation  of the  environment  has
resulted in the enactment of a broad range of environmental laws and regulations
by  local,  state  and  federal  lawmakers  and  agencies.  These  laws  and the
implementing  regulations affect nearly every industry,  as well as the agencies
of  federal,  state  and  local  governments  charged  with  their  enforcement.
Recently,   the  level  of  enforcement  has  waned  given  governmental  budget
constraints and a number of environmental laws set for renewal have been allowed
to lapse.  Nonetheless,  those laws and regulations still in force will continue
to  stimulate  demand  for the kinds of  services  offered  by EMCON.  They also
subject the Company to stringent regulation in the conduct of its operations.

                        Potential Liability and Insurance

The Company's work involves assisting clients in handling, storing and disposing
of  hazardous  materials,  toxic  wastes  and other  pollutants,  as well as the
remediation  of existing  contamination.  The Company  therefore is exposed to a
significant risk of professional liability for environmental damage and personal
injury.

                                       8


EMCON maintains health and safety and quality assurance/quality control programs
to  reduce  the  risk of  potential  damage  to  persons  and  property  and the
associated   potential  liability.   In  addition,   EMCON  currently  maintains
professional  liability  insurance  (covering  damages  resulting from negligent
acts,  errors,  mistakes  or  omissions  in  rendering  or failing to render its
professional  services)  as  well  as  commercial  general  liability  insurance
(covering bodily injury and property damage).

EMCON endeavors contractually to limit its potential liability to the amount and
terms of its  insurance  policies,  and to be  indemnified  by its clients  from
potential liability to third parties. However, the Company is not always able to
obtain such  limitations on liability or  indemnification,  and such provisions,
when  obtained,   may  not  adequately   shelter  the  Company  from  liability.
Consequently,  a partially or completely  uninsured  claim, if successful and of
sufficient  magnitude,  could have a material  adverse effect on the Company and
its financial condition and results of operations.

Although the  liabilities  arising out of  environmental  laws are more directly
applicable  to the Company's  clients,  such laws could,  under certain  factual
circumstances,  apply to some of the  activities  pursued by the  Company in the
course of business,  including failure to properly design a cleanup,  removal or
remedial  action  plan or failure  to  achieve  required  cleanup  standards  in
compliance  with  such laws and  standards.  Such  liabilities  can be joint and
several where other parties are involved. Because much of the Company's business
is  generated  either  directly or  indirectly  as a result of federal and state
governmental   programs  and  regulations,   changes  in  governmental  policies
affecting such programs, or regulations or administrative  actions affecting the
funding or sponsorship of such programs, could have a material adverse effect on
the Company's business. See Item 3 - Legal Proceedings.

                                   Competition

EMCON competes  directly with a wide variety of national and local  engineering,
consulting,  construction,  equipment,  and operations and maintenance companies
which offer services similar to those provided by the Company.  However, many of
these  competitors  are only engaged in certain  segments of the industry and do
not provide the broad range of services  provided by the  Company.  In addition,
the  Company  competes   indirectly  with  remediation   companies  which  offer
environmental  consulting and engineering  services,  as well as transportation,
storage or disposal  capabilities  generally not provided by EMCON.  The Company
believes  that the  principal  competitive  factors in its  industry  are price,
reputation, technical proficiency, management experience and breadth of services
offered. The industry has also experienced a significant amount of consolidation
activity.  Management  anticipates  that  these  trends  will  continue  for the
foreseeable future.

                                    Employees

As of December 31, 1996, the Company had a total of 1,057 employees,  including:
454 professionals;  279 technical personnel;  and 324 administrative and support
personnel.   The  Company's   professional  staff  includes   chemical,   civil,
geotechnical,  mechanical,  electrical and environmental  engineers;  marine and
terrestrial biologists;  oceanographers; plant ecologists; chemists; geologists;
hydrogeologists;  hydrologists  and  toxicologists.  The  Company's  ability  to
attract and retain qualified engineers, scientists and other professionals is an
important factor in determining its future success. EMCON's employees have never
been  represented  by a union,  and the Company  believes its relations with its
employees are good.

                                     Backlog

The Company  estimates  that at  December  31,  1996,  the backlog of future net
revenue from  contracts in existence and orders  believed to be firm  (excluding
CAS) was in excess  of $80  million,  all of which is  expected  to be  received
within the next twelve months,  compared to $55 million  backlog at December 31,
1995. However, there can be no assurance that this work will not be postponed or
canceled.  Furthermore, a substantial portion of the Company's work is performed
pursuant to agreements by which the Company is compensated for time and expenses
devoted to projects with indefinite lives.

Item 2.       PROPERTIES

The  Company's  corporate  office,  located in San Mateo,  California,  occupies
approximately  3,000 square feet and is leased through July, 2001. The Company's
accounting center,  located in Sacramento,  California,  occupies  approximately
4,000 square feet and is leased through December 31, 1997.

The  Company  owns a 25,000  square-foot  building  in  Kelso,  Washington.  The
facility  includes  office  and  warehouse  space and  currently  houses the CAS
corporate operations.

The Company  leases  office,  warehouse  and  laboratory  space in a total of 72
facilities  located  in  Alaska,  Arizona,  California,   Connecticut,  Florida,
Georgia, Illinois, Iowa, Maine, Massachusetts, Michigan, Nevada, New Jersey, New
York, Ohio,  Oregon,  Pennsylvania,  Puerto Rico, Texas,  Vermont,  Virginia and
Washington  under leases expiring at various times through  December 2002. These
facilities have a combined area of approximately 482,000 square feet.

Item 3.       LEGAL PROCEEDINGS

As a firm  engaged in  environmental-related  matters,  the  Company  encounters
potential liability,  including claims for significant  environmental damage, in
the normal course of business.  The Company is party to lawsuits and is aware of
potential  exposure related to certain claims. In the fourth quarter of 1996 the
Company agreed to settlement terms on a number of outstanding legal matters.  At
the same time the Company assessed the potential  exposure relative to all other
known pending matters.  Based on the foregoing,  the Company increased its legal
reserve by an additional $1,553,000. In the opinion of management the resolution
of all known  lawsuits/claims at amounts in excess of established  reserves will
not have a material adverse affect on the Company's financial position,  results
of operations or cash flows.

Item 4.       SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no matters  submitted  to a vote of the security  holders  during the
fourth quarter of the fiscal year ended December 31, 1996.

On February 28, 1997,  there were 579  shareholders  of record of the  Company's
common stock.

Although the Company does make annual distributions to a minority shareholder of
one of the OWT  subsidiaries,  the Company did not pay cash  dividends  to EMCON
shareholders  in 1996 or 1995 and does  not  plan to pay cash  dividends  to its
shareholders in the near future.  Furthermore,  the payment of cash dividends is
restricted  by the  Company's  bank  line of  credit  arrangement.  The  Company
presently intends to retain earnings for further development of its business.

Item 7.       MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
              AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

The following  table sets forth (i) certain items in the Company's  Consolidated
Statements of Operations as a percentage of net revenue and (ii) the  percentage
increase  (decrease)  in the  dollar  amount  of  those  items  for  the  period


                                       12


indicated.  Net  revenue  is  determined  by  subtracting  the costs of  outside
subcontractor services,  largely drilling contractors and specialized consultant
services,  from gross revenue. Since EMCON's use of subcontractors can vary from
period to period  and the costs of these  services  are passed  directly  to the
Company's  clients,  the Company  believes  that net revenue is a more  accurate
measure of the value of its services.

Net Revenue:

Net revenue for 1996 increased by 13.8% to  $117,705,000  from  $103,409,000  in
1995.  Excluding  net  revenue  of  $20,596,000  contributed  by  Organic  Waste
Technologies,  Inc. ("OWT"), following its acquisition on February 29, 1996, net
revenue in 1996 totaled $97,109,000, a 6.1% decrease from 1995. The decrease was
primarily   attributable  to  significant   underperformance  of  the  Company's
Professional  Services Division  (formerly known as the Consulting  Division) in
the Alaska,  Washington and Southeast markets,  combined with a general decrease
in revenue following recent reductions in work force throughout the Professional
Services  Division.  The decrease was, to a lesser extent,  also attributable to
particularly  difficult weather  conditions in the Northeast and Northwest areas
during the first quarter.

Net revenue for 1995  increased by 7.8% over net revenue of $95,926,000 in 1994.
The  increase  in net  revenue in 1995 was partly  attributable  to  significant
improvements  in the  Company's  consulting  division in its West and  Southeast
areas. The increase was also due in part to the inclusion of Wehran  Envirotech,
Inc.  ("Wehran")  for all of 1995 as  compared  to all but the first  quarter of
1994,  following its acquisition in April of 1994.  Although Wehran  contributed
net revenue of  $5,472,000  in the  quarter  ended  March 31,  1995,  due to the
underperformance  of  their  Northeast  and  Midwest  operations,   Wehran  only
contributed  an  additional  $3,730,000  in net  revenue in 1995 over 1994.  Net
revenue  was  also  positively  impacted  by the  expansion  of  the  laboratory
division's operations in Florida and Southern California.



                                       13


Direct Expenses:

Direct expenses in 1996 were  $52,608,000,  a 33.3% increase over $39,473,000 in
direct expenses in 1995.  Excluding  direct expenses of $14,744,000  incurred by
OWT,  direct  expenses in 1996 totaled  $37,864,000,  a 4.1% decrease from 1995.
Direct  expense  includes  compensation  for billable  hours for  technical  and
professional  staff and other project related expenses,  as well as direct labor
and  materials  for in-house  laboratory  testing and  construction  activities.
Excluding OWT, direct expenses,  as a percent of net revenue in 1996,  increased
to 39.0% from 38.2% in 1995;  due largely to relative  increases  in the cost of
labor and materials within the laboratory division.

Direct  expenses in 1995 were up 5.8% over direct  expenses  of  $37,307,000  in
1994.  The increase was due in part to higher  overall  salary costs,  increased
utilization of technical and professional staff, and the inclusion of Wehran for
all of 1995 versus only the last three quarters of 1994 (Wehran  incurred direct
expenses of $7,739,000 and $6,524,000 in 1995 and 1994, respectively). The ratio
of direct expenses to net revenue in 1995 decreased to 38.2% from 38.9% in 1994.

Indirect Expenses:

Indirect  expenses  totaled  $65,844,000  in 1996, an increase of 7.1% over 1995
indirect  expenses of  $61,498,000.  Excluding  indirect  expenses of $3,173,000
incurred by OWT, indirect expenses in 1996 totaled $62,671,000,  a 1.9% increase
over 1995.  Indirect expenses include salary  compensation for nonbillable hours
for professional and technical  staff, and general and  administrative  expenses
such  as  facility  rent,  bonuses,  benefits,  insurance,   depreciation,   and
legal/settlement expenses.  Excluding OWT, indirect expenses as a percent of net
revenue in 1996  increased to 64.5% from 59.4% in 1995; due in part to the above
noted decrease in net revenue, combined with the effect of significant severance
costs and expenses  related to the closing of several small  offices  during the
first nine months of 1996.  In addition,  during the fourth  quarter of 1996 the
Company  increased  reserves  relating  to  pending  litigation  matters  by  an
additional $1,553,000.

Indirect  expenses  in 1995  increased  by 3.7% over 1994  indirect  expenses of
$59,302,000.  The ratio of indirect expenses to net revenue decreased from 61.8%
in 1994  to  59.4%  in  1995,  due to  improved  utilization  of  technical  and
professional  staff as well as  selective  reductions  in force and  other  cost
containment and restructuring measures put in place during the fourth quarter of
1994 and throughout 1995.

Restructuring/Other Charges:

In the  fourth  quarter  of  1996,  senior  management  reviewed  the  Company's
operational and  administrative  functions for the purpose of further  improving
the Company's  competitiveness and overall profitability.  Based on this review,
the  Company's  Board of Directors  approved a strategic  restructuring  plan in
December,  1996 to reposition the Company to fully exploit its core strengths in
engineering,  design,  construction,  operations and maintenance. As a result of
these actions, the Company recognized pre-tax restructuring and other charges of
$1,237,000 and $6,960,000,  respectively.  Included in the restructuring  charge
were $604,000  relating to the closure or downsizing of several  underperforming
offices,  $628,000 related to employee severance and the write-off of employment
contracts for former employees no longer actively participating in the Company's
affairs,  and a $5,000 adjustment to the 1994  restructuring  plan.  Included in

other charges were $4,768,000 related to the write-down in the carrying value of
goodwill associated with the Company's  continuing operating units in accordance
with the Statement of Financial  Accounting  Standards No. 121,  "Accounting for
the  Impairment of Long-Lived  Assets and for  Long-Lived  Assets to Be Disposed
Of", $1,529,000 related to the write-off of idle or disposed of assets, $368,000
related to the write-down of the Company's  landfill gas  production  rights and
related  fixed assets, and $156,000  related to the buyout and  cancellation  of
outstanding  stock  options  to  purchase  approximately  743,000  shares of the
Company's common stock held by employees of the Company. Also, included in other
charges were $139,000 for various other operational costs.

Anticipated savings in 1997 from the restructuring charge alone are estimated to
exceed $1,500,000.  As of December 31, 1996,  $119,000 of the 1996 restructuring
adjustment   has  been  incurred  and   $1,113,000   remains  in  other  accrued
liabilities. All remaining actions are expected to be substantially completed by
the third quarter of 1997.

In October 1994, the Board of Directors  appointed  Eugene M. Herson to serve as
the Company's new President and Chief Executive Officer. Shortly thereafter,  in
December,  1994, the Company's Board of Directors  approved senior  management's
recommendation to implement a restructuring plan designed to improve operational
efficiencies.  Under the plan, the Company  eliminated  substantially all of its
regional  consulting  subsidiaries  in  favor  of  a  divisional  structure.  In
addition,  the Company  consolidated  and  streamlined  all  unnecessary  and/or
redundant  administrative  functions.  As a result  of the  actions  taken,  the
Company recognized a pre-tax  restructuring charge in the fourth quarter of 1994
of $1,181,000.  Of this amount,  $611,000 related to the write-off of employment
contracts for former employees no longer actively participating in the Company's
affairs,  $287,000 related to employee severance,  and $263,000 related to costs
associated with excess  facilities and equipment.  Anticipated  savings from the
1994  restructuring  plan were estimated to exceed $1,000,000 per year. To date,
$1,142,000 of  restructuring  costs have been incurred and adjustments of $5,000
and  ($17,000)  were made to  increase/(reduce)  the  reserve  in 1996 and 1995,
respectively,  to the required remaining balances. At December 31, 1996, $27,000
of accrued  restructuring  costs for write-off of  employment  contracts in 1994
were included in accrued  liabilities in the accompanying  consolidated  balance
sheet.  All remaining  actions are expected to be completed by the first quarter
of 1997.

During the fourth  quarter  of 1994,  the  Company  also  incurred  nonrecurring
charges of $777,000  related to the  write-down of the carrying value of certain
of the Company's  landfill gas  production  rights and of certain  related fixed
assets due to the  reevaluation  of future cash flows  expected to be  generated
from the related projects.

Impairment of Assets Held for Sale:

In December 1996, the Company executed a letter of intent to sell its laboratory
division,  Columbia Analytical  Services,  Inc. ("CAS"), to the employees of CAS
for  cash,  notes  and  other  consideration  valued  in total at  approximately
$7,500,000.  The transaction is expected to be completed by the first quarter of
1997. In anticipation  of the sale, the Company  recognized an impairment in its
investment in CAS of $3,327,000; including a write-down in the carrying value of
goodwill associated with previous laboratory acquisitions of $1,426,000.
For the year ended December 31, 1996, CAS had a loss before taxes of $142,000.

Interest Income:

The Company recorded interest income of $317,000 in 1996 compared to $369,000 in
1995 and $348,000 in 1994.



                                       15


Interest Expense:

The Company incurred interest expense of $1,112,000 in 1996 compared to $181,000
in 1995. The increase in interest expense in 1996 over 1995 was due primarily to
increases in long-term  debt of  $11,747,000  incurred for purposes of financing
the  acquisition  of OWT in  February  of 1996 and  $5,000,000  for  purposes of
financing the subsequent expansion of OWT's landfill gas-to-energy project.

The  increase  in  interest  expense in 1995 over 1994 was  primarily  due to an
imposition of interest on a one-time state tax assessment  with respect to prior
years.

Income Taxes Provision (Benefit):

The provision  (benefit) for income taxes in 1996 was  ($2,936,000)  compared to
$783,000 for 1995 and  ($500,000)  for 1994. The effective tax rate for 1996 was
(22.5%)  versus  30.5% in 1995 and  (20.7%)  for 1994.  The 1996 tax  benefit is
primarily  due to  the  alternative  minimum  tax  credits  generated  from  the
Company's landfill  gas-to-energy  project and from temporary timing differences
consisting of the restructuring charges,  impairment of assets held for sale and
the legal reserve.

Included in the  Company's  balance sheet at December 31, 1996 are total current
and long-term net deferred tax assets of  $6,455,000.  The full  utilization  of
such  assets is  dependent  upon a number of  factors  including  the  Company's
ability  to  generate  future  profits,  the  successful  implementation  of the
Company's  restructuring plan and the anticipated  reduction in the level of new
tax  credits  generated  from  the  Company's  existing  landfill  gas-to-energy
projects.  Based on these factors,  the Company  believes that it is more likely
than not that the full  benefit of the net  deferred tax assets will be realized
by the Company in due course.

SUBSEQUENT MATTERS

On March  6,  1997,  the  Company  completed  the  sale of its  Marina  landfill
gas-to-energy  project for a net up front cash payment of $800,000.  The Company
is eligible to receive an additional $200,000 prior to December 31, 1997 subject
to certain post-closing  contingencies - specifically,  that no material adverse
changes are made to the provisions of Section 29 of the Internal Revenue Code of
1986, as amended, pertaining to the availability of unconventional fuel credits.

LIQUIDITY AND CAPITAL RESOURCES

Working Capital:

Cash  provided  by  operating  activities  for  fiscal  1996,  1995 and 1994 was
$1,583,000,  $5,232,000,  and  $4,875,000,  respectively.  The  changes  in cash
provided  by  operating  activities  in  1996,  1995  and  1994  were  primarily
attributed to changes in the Company's net income  (loss),  accounts  receivable
and accounts payable and in 1996 and 1995, depreciation and amortization.  Cash,
cash equivalents, and marketable securities decreased to $5,331,000 in 1996 from
$9,952,000 in 1995.

In  conjunction  with  the  acquisition  of  OWT,  the  Company  entered  into a
$20,000,000   secured  credit  agreement  with  its  existing  commercial  bank,
replacing  its  previous  $10,000,000  unsecured  line of credit.  Under the new
agreement,  the  Company  borrowed  $10,000,000  on a term  loan  basis  with an
interest  at a managed  rate not to exceed the prime  rate.  Principal  is to be


                                       16


amortized  over seven years,  but with any unpaid amount finally due and payable
on June 30,  2001.  The  remaining  $10,000,000  under the Credit  Agreement  is
available  for  working  capital  purposes  (with up to  $5,000,000  also  being
available for non-working capital purposes). The line of credit component of the
Credit Agreement  expires on May 31, 1997. The Company expects to renew the line
of credit component of the Credit Agreement following its expiration. The Credit
Agreement  contains  provisions with respect to the payment of dividends and the
level of capital expenditures and requires the maintenance of specific levels of
working capital, tangible net worth and continued quarterly profitability.  As a
result  of  the  fourth  quarter  loss  in  1996,  the  impact  of  the  related
restructuring  actions  and the  payment of certain  profit  distributions  to a
minority  shareholder  in one of  OWT's  subsidiaries,  the  Company  was not in
compliance with these  covenants at year-end.  However,  the Company  obtained a
waiver from the bank for its non compliance and agreed to related  amendments of
the Credit Agreement  reducing the tangible net worth requirement and permitting
distribution to the minority shareholder in OWT's subsidiary.

Capital Expenditures:

The Company invested  $2,484,000 in 1996 in additions to property and equipment;
mainly computers,  field and laboratory equipment. The Company believes that its
cash on hand and cash  generated  from  operations,  together with its available
bank  financing  will be sufficient  to meet the Company's  capital needs for at
least the next twelve months.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation:

The accompanying  consolidated  financial statements include the accounts of the
Company and its wholly owned  subsidiaries  after elimination of all significant
intercompany  accounts and  transactions.  Certain  amounts in the 1995 and 1994
financial statements have been reclassified to conform to the 1996 presentation.

In 1994,  the Company  converted  to a  fifty-two/fifty-three  week fiscal year,
resulting in a fifty-three  week year in 1996 and a fifty-two week year in 1995.
The  Company's  year end  falls  on the  Friday  closest  to the last day of the
calendar  quarter.  The Company also  follows a  five-four-four  week  quarterly
cycle.  While the actual  period  ends for the  fiscal  years 1996 and 1995 were
January 3, 1997 and December 29, 1995, respectively,  for convenience,  the date
shown on accompanying  financial  statements is December 31, the last day of the
calendar periods.

Use of Estimates in the Preparation of Financial Statements:

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

Revenue Recognition and Expenses:

Revenue  from  engineering  service  contracts  is  recognized  as services  are
provided and revenue from construction projects is recognized on a percentage of
completion basis. The Company routinely subcontracts for outside services,  such
as drilling  and  specialized  laboratory  services.  These costs are  generally
passed through to the Company's customers. The Company believes net revenue is a
more accurate  measure of the value of its services than gross  revenue.  Direct
costs include  compensation  for billable hours for  professional  and technical
staff and other project expenses  reimbursed by clients.  Indirect costs include
compensation  for  non-billable  professional  and  technical  staff hours,  all
employee fringe benefits,  marketing,  and general and  administrative  expenses
such as rent, insurance and depreciation.

Cash and Cash Equivalents and Marketable Securities:

The Company considers all investment  instruments and marketable securities with
an original  maturity date of 90 days or less at the date of purchase to be cash
equivalents.  Management  determines  the  appropriate  classifications  of debt
securities at the time of purchase and reevaluates  such  designation as of each
balance  sheet  date.  Investments  consisting  primarily  of  high  grade  U.S.
government  and  corporate   marketable   debt   securities  are  classified  as
available-for-sale,  and are  carried  at fair  value,  based on  quoted  market
prices, with the unrealized gains and losses, net of tax, reported in a separate
component of shareholders'  equity.  The cost of debt securities is adjusted for
amortization  of premiums and  accretion  of  discounts  to  maturity,  which is


                                       23


included in interest  income.  Realized  gains and losses and  declines in value
judged to be other-than-temporary,  as well as any interest on these securities,
are included in interest  income.  The cost of  securities  sold is based on the
specific  identification method. There were no available-for-sale  securities as
of December 31, 1996.

The following is a summary of  available-for-sale  securities as of December 31,
1995:
- -------------------------------------------------------------------------------

U.S. Treasury Bills/Notes     $514,000     $ -         $13,000        $501,000
- -------------------------------------------------------------------------------

All  marketable  securities  held by the  Company as of  December  31, 1995 were
available for the Company's current working capital  requirements and matured in
less than one year.  Accordingly,  all such amounts were  classified  as current
assets in the accompanying consolidated balance sheets.

Supplemental Cash Flow Information:

Cash paid for income taxes was approximately $659,000,  $58,000 and $469,000 for
the years ended December 31, 1996,  1995 and 1994,  respectively.  Cash paid for
interest was  approximately  $951,000,  $181,000 and $66,000 for the years ended
December 31, 1996, 1995 and 1994, respectively.

In 1995,  the Company sold certain land and buildings in exchange for $1,100,000
in marketable trade credits which will be used to reduce cash payments of future
recurring  corporate  expenses.  No significant gain or loss was incurred on the
transaction. The trade credits expire in eight years, and the Company expects to
utilize such credits prior to  expiration.  The Company has  agreements  for the
utilization  of $625,000 of the trade  credits.  $225,000  and $400,000 of these
credits are  included on the  December 31, 1996  consolidated  balance  sheet in
other current  assets and other assets,  respectively.  To-date,  $55,000 of the
trade credits have been applied to payments.  The remaining  balance of $420,000
is included on the December 31, 1996 consolidated balance sheet in other assets.

Income (Loss) per Share:

Primary and fully diluted  earnings per share are  substantially  the same. Loss
per share in 1996 and 1994 were based on the weighted  average  number of common
shares  outstanding.  Income per share in 1995 was based on the weighted average
number of common and dilutive common  equivalent  shares  outstanding  using the
modified treasury stock method. Common equivalent shares are comprised of shares
issuable under the Company's stock option plans.

Business Segment and Concentration of Credit Risk:

The Company operates within one business segment,  which provides  comprehensive
environmental engineering, consulting,  construction,  facilities operations and
maintenance,  and laboratory  services to industrial,  private and  governmental
concerns,  predominantly  in  the  waste  disposal,  petroleum,  wood  products,
chemical and manufacturing industries;  as well as to utilities,  non-regulatory
government entities,  financial  institutions and real estate developers.  There
are no  significant  operations  or revenues  generated  from non United  States
locations.  Ongoing credit evaluations of its customers' financial condition are
performed by the Company, generally requiring no collateral.

3. RESTRUCTURING/OTHER CHARGES

In the  fourth  quarter  of  1996,  senior  management  reviewed  the  Company's
operational and  administrative  functions for the purpose of further  improving
the Company's  competitiveness and overall profitability.  Based on this review,
the  Company's  Board of Directors  approved a strategic  restructuring  plan in
December,  1996 to reposition the Company to fully exploit its core strengths in
engineering,  design,  construction,  operations and maintenance. As a result of
these actions, the Company recognized pre-tax restructuring and other charges of
$1,237,000 and $6,960,000,  respectively.  Included in the restructuring  charge
were $604,000  related to the closure or  downsizing of several  underperforming
offices,  $628,000 related to employee severance and the write-off of employment
contracts for former employees no longer actively participating in the Company's
affairs,  and a $5,000 adjustment to the 1994  restructuring  plan.  Included in


                                       25


other charges were $4,768,000 related to the write-down in the carrying value of
goodwill associated with the Company's  continuing operating units in accordance
with the Statement of Financial  Accounting  Standards No. 121,  "Accounting for
the  Impairment of Long-Lived  Assets and for  Long-Lived  Assets to Be Disposed
Of", $1,529,000 related to the write-off of idle or disposed of assets, $368,000
related to the write-down of the Company's  landfill gas  production  rights and
related  fixed assets, and $156,000  related to the buyout and  cancellation  of
outstanding  stock  options  to  purchase  approximately  743,000  shares of the
Company's common stock held by employees of the Company. Also, included in other
charges were $139,000 for various  other  operational  costs.  Fair value of the
goodwill associated with the Company's  continuing  operating units was based on
each operating unit's expected future discounted cash flows.

As of December 31, 1996, $119,000 of the 1996 restructuring  adjustment has been
incurred and  $1,113,000  remains in other  accrued  liabilities.  All remaining
actions are expected to be substantially completed by the third quarter of 1997.

In October 1994, the Board of Directors  appointed  Eugene M. Herson to serve as
the Company's new President and Chief Executive Officer. Shortly thereafter,  in
December,  1994, the Company's Board of Directors  approved senior  management's
recommendation to implement a restructuring plan designed to improve operational
efficiencies.  Under the plan, the Company  eliminated  substantially all of its
regional  consulting  subsidiaries  in  favor  of  a  divisional  structure.  In
addition,  the Company  consolidated  and  streamlined  all  unnecessary  and/or
redundant  administrative  functions.  As a result  of the  actions  taken,  the
Company recognized a pre-tax  restructuring charge in the fourth quarter of 1994
of $1,181,000.  Of this amount,  $611,000 related to the write-off of employment
contracts for former employees no longer actively participating in the Company's
affairs,  $287,000 related to employee severance,  and $263,000 related to costs
associated with excess  facilities and equipment.  Anticipated  savings from the
1994  restructuring  plan were estimated to exceed $1,000,000 per year. To date,
$1,142,000 of  restructuring  costs have been incurred and adjustments of $5,000
and  ($17,000)  were made to  increase/(reduce)  the  reserve  in 1996 and 1995,
respectively,  to the required remaining balances. At December 31, 1996, $27,000
of accrued  restructuring  costs for write-off of  employment  contracts in 1994
were included in accrued  liabilities in the accompanying  consolidated  balance
sheet.  All remaining  actions are expected to be completed by the first quarter
of 1997.

During the fourth  quarter  of 1994,  the  Company  also  incurred  nonrecurring
charges of $777,000  related to the  write-down of the carrying value of certain
of the Company's  landfill gas  production  rights and of certain  related fixed
assets due to the  reevaluation  of future cash flows  expected to be  generated
from the related projects.

4. IMPAIRMENT OF ASSETS HELD FOR SALE

In December 1996, the Company executed a Letter of Intent to sell its laboratory
division,  Columbia Analytical  Services,  Inc. ("CAS"), to the employees of CAS
for  cash,  notes  and  other  consideration  valued  in total at  approximately
$7,500,000.  The  transaction  is expected to be completed  the first quarter of
1997. In accordance  with Statement of Financial  Accounting  Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of", the Company  recognized an impairment in its  investment in CAS
of  $3,327,000;  including  a  write-down  in the  carrying  value  of  goodwill
associated with previous  laboratory  acquisitions  of $1,426,000.  For the year
ended December 31, 1996, CAS had a loss before taxes of $142,000.  The estimated
fair value of CAS is reflected in the accompanying  consolidated  balance sheets
as assets held for sale as of December 31, 1996.

5. ACQUISITIONS

Goodwill

On February  29,  1996,  EMCON  acquired all the  outstanding  capital  stock of
Organic  Waste  Technologies,  Inc.  ("OWT"),  a Cleveland  based  construction,
equipment and operations and maintenance  company with significant  expertise in
solid waste  management.  The Company purchased OWT for $13,859,000 in cash plus
the issuance of convertible  notes and other  contractual  indebtedness  held by
certain  senior  OWT  management  in the  principal  amount of  $1,747,000.  The
transaction was accounted for as a purchase.  The indebtedness bears interest at
the rate of 8% per annum with all  principal due and payable in full on March 1,
2001. The  indebtedness may be converted into shares of OWT common stock upon an
underwritten  public  offering of OWT's  common  stock in an amount in excess of
$10,000,000.  In the  event the  indebtedness  has not been  converted  into OWT
shares,  it may instead be  converted  into shares of EMCON  common  stock for a
period of ninety days after November 30, 2001 at a conversion price of $6.50 per
share. Goodwill of approximately  $11,129,000 resulting from this acquisition is
being  amortized  over thirty  years using the  straight  line  method.  Related
accumulated amortization at December 31, 1996, was approximately $310,000.

The following summarizes the unaudited pro forma net revenue, net income (loss),
and income  (loss) per share of the combined  company for the  unaudited  twelve
months  ended  December  31, 1996  compared to  unaudited  twelve  months  ended

The above pro forma  results of operations do not purport to reflect the actual
results of operations had the Company actually  acquired OWT as of the beginning
of 1996.

Effective April 1, 1994, the Company acquired all of the capital stock of Wehran
Envirotech,  Inc. ("Wehran"),  an environmental consulting company headquartered
in Middletown,  New York, in exchange for 410,000 shares of the Company's common
stock  valued at  $2,818,000  and  $439,000  in direct  acquisition  costs.  The
transaction was accounted for as a purchase. An additional 80,000 shares, valued
at $290,000, were issued to Wehran shareholders in December, 1994 as a result of
their attaining certain  predetermined  operating performance goals. Goodwill of
approximately $1,896,000 resulting from this acquisition is being amortized over
twenty years using the  straight  line method.  Accumulated  amortization  as of
December 31, 1996,  was  approximately  $253,000.  Subsequent to the purchase of
Wehran,  the Company issued an additional  425,000 shares of its common stock to
retire approximately  $5,000,000 of Wehran's convertible  subordinated notes. In
addition,  the Company  also paid  approximately  $6,100,000  in cash to satisfy
amounts  borrowed  against  Wehran's  revolving  credit  line  ($5,000,000)  and
obligations due to settlement of certain litigation ($1,100,000).

On May 31, 1996,  EMCON acquired the operations of Cascade Pacific  Engineering,
Inc.  ("Cascade").  The transaction was structured as an asset  acquisition with
EMCON  acquiring  substantially  all the assets of Cascade for  $546,000 in cash
plus the assumption of substantially all of Cascade's liabilities.  The tangible
net assets  were valued at $80,000.  The  $466,000  excess of cost over the fair


                                       27


value of net assets  acquired,  net of accumulated  amortization at December 31,
1996, of $93,000 was subsequently written-off in 1996 due to an evaluation based
on a discounted cash flow analysis.

Acquisitions  made in the  Southeast  and  Alaska  between  1990 and  1993  were
evaluated  based on a discounted cash flow basis and resulted in a write-down of
goodwill of  $4,394,000.  Remaining  goodwill and  accumulated  amortization  at
December 31, 1996 were approximately $1,734,000 and $1,480,000, respectively.

Other Intangible Assets:

Intangible assets include $879,000 and $2,476,000 at December 31, 1996 and 1995,
respectively,   representing   gross  costs  incurred  to  obtain  landfill  gas
production rights.  Amortization of these gas production rights is recognized as
the greater of either the  straight-line  or  units-of-production  method over a
term not  exceeding  the  period  of the gas  production  leases.  The  expected
amortization  periods  range  from one to ten  years.  The  related  accumulated
amortization was approximately  $798,000 and $1,338,000 at December 31, 1996 and
1995,  respectively.  In December,  1996 the Company  reduced the value of these
landfill gas production rights by $247,000 to their estimated fair value.

Other intangible assets at December 31, 1996 also include $888,000, representing
the gross cost to reacquire  certain patent rights associated with the Company's
proprietary leachate evaporation system technology.  Accumulated amortization at
December 31, 1996 was  approximately  $15,000 and the patent is being  amortized
over the 15 year life of such patents.

6. OTHER NONCURRENT OBLIGATIONS

Certain employees  participate in a salary  continuation plan which will provide
the employees with a 10-year  benefit from the Company.  Monthly  benefits range
from $600 to $4,500, and the employees vest in varying amounts from the fifth to
the tenth  anniversary  date of their  contracts.  Such  amounts will be paid in
addition to those payments due specifically as  consideration  for the employees
meeting the non-competition provisions of their contracts.

Included in other  noncurrent  obligations are the Company's  liabilities  under
salary  continuation  agreements and capital  leases.  Liabilities  under salary
continuation  agreements  were  $939,000  and  $802,000 at December 31, 1996 and
1995,  respectively.  Capital lease obligations are  collateralized by equipment
included in property and equipment with a cost and  accumulated  depreciation of
$324,000 and $80,000,  respectively,  at December 31, 1996,  and  $1,020,000 and
$863,000, respectively, at December 31, 1995.

7. RETIREMENT PLAN

The Company  sponsors a qualified  retirement plan,  generally  available to all
employees,  which is based on Section 401(k) of the Internal Revenue.  Employees
may elect to contribute up to 15% of their annual compensation to the plan up to
the Internal  Revenue  Service  annual  contribution  limit $9,500 for 1996. The
Company  voluntarily  matched the employee's  contribution to a maximum of 3% of
annual  compensation.  The Company's  contributions  to the retirement plan were
$1,146,000,  $1,177,000 and $674,000 for the years ended December 31, 1996, 1995
and 1994, respectively.

8. COMMITMENTS

The  Company  leases  its  office  facilities,  as well as office  and  computer
equipment,  under operating  leases in various  locations.  Until 1995,  certain
office  facilities were leased from  partnerships in which certain  officers and
shareholders of the Company had controlling  interests.  Lease arrangements with
the  partnerships  were  terminated in 1995.  The annual rents under leases from
partnerships  were  approximately  $473,000  and  $516,000  for 1995  and  1994,
respectively. The Company's minimum annual lease commitments under all operating
leases are approximately (in thousands):

Rent expense was  approximately  $5,263,000,  $4,429,000  and $3,964,000 for the
years ended December 31, 1996, 1995 and 1994, respectively.

Certain employees have signed non-competition agreements which will provide them
with  monthly  payments  from  $400 to $3,000  for a period of up to ten  years,
commencing on the tenth anniversary date of the agreements. (See note 6.)

9. LITIGATION

As a firm  engaged in  environmental-related  matters,  the  Company  encounters
potential liability,  including claims for significant  environmental damage, in
the normal course of business.  The Company is party to lawsuits and is aware of
potential  exposure related to certain claims. In the fourth quarter of 1996 the
Company agreed to settlement terms on a number of outstanding legal matters.  At
the same time the Company assessed the potential  exposure relative to all other
known pending matters.  Based on the foregoing,  the Company increased its legal
reserve by an additional $1,553,000. In the opinion of management the resolution
of all known  lawsuits/claims at amounts in excess of established  reserves will
not have a material adverse affect on the Company's financial position,  results
of operations or cash flows.

replacing  its  previous  $10,000,000  unsecured  line of credit.  Under the new
agreement,  the Company borrowed  $10,000,000 on a term loan basis with interest
at a managed  rate not to exceed the prime rate.  Principal  is to be  amortized
over seven years, but with any unpaid amount finally due and payable on June 30,
2001.  The  remaining  $10,000,000  under the Credit  Agreement is available for
working  capital  purposes  (with up to  $5,000,000  also  being  available  for
non-working  capital  purposes).  The line of  credit  component  of the  Credit
Agreement  expires on May 31,  1997.  The  Company  expects to renew the line of
credit  component of the Credit Agreement  following its expiration.  The Credit


                                       30


Agreement  contains  provisions with respect to the payment of dividends and the
level of capital expenditures and requires the maintenance of specific levels of
working capital, tangible net worth and continued quarterly profitability.  As a
result  of  the  fourth  quarter  loss  in  1996,  the  impact  of  the  related
restructuring  actions  and the  payment of certain  profit  distributions  to a
minority  shareholder  in one of  OWT's  subsidiaries,  the  Company  was not in
compliance with these  covenants at year-end.  However,  the Company  obtained a
waiver from the bank for its non compliance and agreed to related  amendments of
the Credit Agreement  reducing the tangible net worth requirement and permitting
distributions to the minority shareholders in OWT's subsidiary.

                                       31


Restricted Stock Plan:

The Company's  Restricted  Stock Plan was approved by its  shareholders  in May,
1991. A total of 225,000 shares of the Company's  Common Stock were reserved for
issuance under the Restricted Stock Plan.  Shares granted to employees under the
Restricted Stock Plan generally vest in equal annual  installments  over periods
ranging  from three to four years.  At December  31,  1996,  99,191  shares were
available for issuance.

Employee Stock Purchase Plan:

The  Employee  Stock  Purchase  Plan  (ESPP)  provides  that  substantially  all
employees may purchase the Company's common stock at a price equal to 85% of its
fair value on certain  specified dates via a payroll deduction plan. At December
31, 1996, 248,338 shares were available for issuance.  The Company  discontinued
the ESPP effective February 1, 1997.

Stock-Based Compensation:

As  permitted  under  FASB  Statement  No.  123,   "Accounting  for  Stock-Based
Compensation"   (FASB  123),  the  Company  has  elected  to  follow  Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB
25) in accounting for stock-based awards to employees. Under APB 25, the Company
generally recognizes no compensation expense with respect to such awards.

Pro Forma information  regarding net income (loss) and earnings (loss) per share
is required by FASB 123 for awards  granted  after  December 31, 1994, as if the
Company had accounted  for its  stock-based  awards to employees  under the fair
value method of FASB 123. For these  purposes,  the fair value of the  Company's
stock-based  awards to employees  was  estimated  using a  Black-Scholes  option
valuation model. The Black-Scholes  option valuation model was developed for use
in  estimating   the  fair  value  of  traded  options  which  have  no  vesting
restrictions and are fully  transferable.  In addition,  the Black-Scholes model
requires the input of highly subjective assumptions including the expected stock
price  volatility.  Because the Company's  stock-based  awards to employees have
characteristics  significantly  different  from  those of  traded  options,  and
because changes in the subjective  input  assumptions can materially  affect the
fair  value  estimate,  in  management's  opinion,  the  existing  models do not
necessarily  provide  a  reliable  single  measure  of  the  fair  value  of its
stock-based  awards to employees.  The fair value of the  Company's  stock-based
awards to  employees  was  estimated  assuming  no  expected  dividends  and the
following weighted-average assumptions.

- -------------------------------------------------------------------------------



                                       32


For pro forma  purposes,  the estimated fair value of the Company's  stock-based
awards to employees is amortized over the options'  vesting period (for options)
and the six-month  purchase  period (for stock  purchases  under the ESPP).  The
Company's pro forma information follows:

- ---------------------------------------------------------------------------------------------------------------


Because FASB 123 is applicable only to awards granted subsequent to December 31,
1994, its pro forma effect will not be fully reflected until approximately 1999.

The  weighted  average  fair value of options  granted  during 1996 and 1995 was
$2.14 and $2.30 per share, respectively.

At December 31, 1995,  1,562,833  shares were exercisable at an average exercise
price of $8.10 per share.

In December,  1996 employees  (other than officers and  directors)  with options
having  exercise  prices of $5.00 per share or  greater  were given the right to
either sell back their options to the Company, to exchange their options for new
options,  to retain their original  options or elect a combination of the three.
The rates at which the  outstanding  options  could be exchanged or sold back to
the Company varied depending on the original option exercise price. Participants
could  exchange  their  outstanding  stock options for newly granted  options at
rates  ranging  from one new share for every three old option  shares to one new
share for every five old option shares.  Alternatively,  participants could sell
back their options at prices ranging from $0.10 to $0.40 per option share.  This
resulted in options for 743,319 shares being  canceled for a cash  settlement of
approximately  $156,000,  and an additional  203,727 shares canceled in exchange
for the grant of new options  covering  47,247  shares  with an option  exercise
price of $3.68 per share.

The Board of Directors and Shareholders
EMCON

We have  audited the  accompanying  consolidated  balance  sheets of EMCON as of
December  31,  1996  and  1995,  and  the  related  consolidated  statements  of
operations,  shareholders' equity, and cash flows for each of the three years in
the period  ended  December  31, 1996.  Our audits also  included the  financial
statement schedule listed in the Index at Item 14(a). These financial statements
and  schedule  are  the   responsibility  of  the  Company's   management.   Our
responsibility  is to  express  an opinion  on these  financial  statements  and
schedule based on our audits.

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

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the consolidated financial position of EMCON at December
31, 1996 and 1995, and the  consolidated  results of its operations and its cash
flows for each of the three years in the period  ended  December  31,  1996,  in
conformity with generally accepted accounting principles.  Also, in our opinion,
the related  financial  statement  schedule,  when considered in relation to the
basic  financial  statements  taken as a whole,  present  fairly in all material
respects the information set forth therein.
