CONSULTING AND ENGINEERING

       The Company's consulting and engineering services involve the
identification and characterization of a client's problems; the evaluation of
alternative solutions; and the selection, design, and development of a
technologically feasible, cost-effective, and politically acceptable solution.
These services use professionals from many different scientific and
technological disciplines to assess the long-term effects and the risks
associated with the ultimate environmental impact of clients' activities and
products.  In performing environmental impact and risk assessments, the
Company's professionals examine the relative effectiveness of various
technological approaches for achieving permanent solutions and ensuring that
additional environmental concerns are not created in the course of solving the
primary problem.

       The Company applies its skills to all phases of environmental matters,
including those relating to hazardous and toxic substances; major program
management; sustainable development services; solid waste management;
management of wastewater, groundwater, and air resources; indoor air quality;
health and safety; and energy conservation.

       HAZARDOUS AND TOXIC SUBSTANCES.  Services relating to hazardous and
toxic substances include the assessment of potentially hazardous waste and
toxic materials; the reduction or elimination of sources of hazardous and toxic
materials; the undertaking of remedial investigation and engineering
feasibility studies; the operation of hazardous waste treatment systems; and
consulting to obtain government environmental permits. A majority of the
Company's operations is related to hazardous and toxic substances. The Company
provides engineering for the destruction or detoxification and stabilization of
hazardous waste.

       MAJOR PROGRAM MANAGEMENT.  Major program management involves all phases
of large-scale environmental and health and safety problems of industry and
government.  The Company has the ability to accept overall responsibility for
siting, evaluating, designing, implementing, and managing environmental
programs, and to apply its diversified services, as appropriate, in an
integrated systems approach.  The Company provides the management systems and
the direct involvement of its most senior management to deal with the
complexities of the underlying environmental problems, as well as the
commitment of large numbers of personnel at geographically dispersed sites for
extended timeframes.  The Company typically bids for contracts as the prime
contractor and forms subcontractor teams in those instances where
subcontractors provide expertise and staffing that will substantially enhance
the Company's ability to obtain and perform contracts.  Subcontractors may
include certain competitors of the Company.  Although the Company believes that
major program management will be increasingly used by industry as environmental
issues become more challenging, the primary market for major program management
services is the federal government.

       SUSTAINABLE DEVELOPMENT.  The Company provides advice and counsel to
government and industry to help clients assess and reduce the total
environmental impact of their processes, products, and packaging by looking at
the full product life cycle from raw materials acquisition, through design,
manufacturing, distribution, use and reuse/recycling or disposal. The Company
also provides services to integrate environmental, economic, and social
considerations in its clients' businesses and operations, intended to improve
environmental and financial performance.

       SOLID WASTE MANAGEMENT.  Solid waste services include planning, decision
making, and project implementation for recycling, composting, materials
processing, source reduction, waste-to-energy and landfill programs and
facilities.  The Company provides total solid waste management services,
including permitting, siting, procurement, design, construction, testing, and
operation of solid waste facilities, as well as expertise in addressing public
awareness and acceptance issues that affect the success of solid waste programs
and facilities.

       MANAGEMENT OF WASTEWATER, GROUNDWATER, AND AIR RESOURCES.  Wastewater
management services include industrial and municipal feasibility studies,
engineering, economic evaluations, and design and consultation regarding the
operation of wastewater treatment facilities.  Wastewater treatment facilities
are required by certain industries for the treatment of polluted water
generated by various manufacturing processes and by municipalities for the
treatment of sewage.  The Company provides groundwater and surface water
resource management services, including water quality monitoring and
assessment, studies of the impact of surface and subsurface activities on
aquifer systems, development of water supplies, and development of resource
management programs.  Air resources management services include siting and
obtaining permits for air pollution control facilities, sampling and monitoring
emissions, regulatory compliance, and designing and monitoring of facility
construction and other systems for the removal of particulate matter,  acid
gases, and other pollutants.  Regulatory compliance services include reviews of
clients' facilities to determine current and future degrees of compliance with
pollution standards.  Site assessment reviews involve the inspection of a
facility to identify the environmental risks and potential environmental
effects of discharges of toxic emissions.

       INDOOR AIR QUALITY.  The Company integrates many of its engineering
services to define and solve indoor air quality problems, including asbestos,
radon, toxic air pollutants and "sick-building syndrome."  Assessment
techniques are aided by state-of-the-art electron and optical microscopy and
chemical analysis.  Industrial hygiene professionals work closely with design
engineers in solving indoor air quality problems.

       HEALTH AND SAFETY.  Health and safety specialists coordinate industrial
hygiene, safety, training, and medical surveillance programs; conduct
inspections; and prescribe protection and compliance procedures to be used when
working with hazardous materials or in hazardous environments.  "Right-to-know"
legislation has increased the demand for services that promote improved
employee safety in the workplace.

       ENERGY CONSERVATION.  The Company has conducted major energy
conservation engineering and management projects for industry and government,
including energy audits, coal conversion studies, alternative energy studies,
and cogeneration system studies for energy producers.

ANALYTICAL LABORATORY SERVICES

       The Company offers services for the detection and measurement of
hazardous materials, toxic wastes, and other chemicals and substances found in
air, soil, and water, and in industrial wastes and emissions.  Services
provided by the Company include source sampling and characterization of organic
pollutants such as pesticides, herbicides, volatile solvents, dioxins, and
PCBs, and inorganic pollutants such as asbestos, trace metals, and sulfur.  The
Company monitors pollutants to assist clients in





                                       4
<PAGE>   6
complying with environmental regulations and to evaluate the ongoing
environmental effects of clients' activities. The Company uses state-of-the-art
computer-assisted equipment, such as gas chromatograph/mass spectrometers, to
measure trace concentrations of pollutants.  A modern microscopy laboratory
provides complete optical scanning microscopic measurements for asbestos
analysis.  The Company also uses a sophisticated data management system to
track the status and results of analyses, to perform quality assurance checks,
to provide sample management and to produce data reports.

       Analytical services are performed in the Company's two laboratories
located in Lionville, Pennsylvania, and University Park, Illinois.  The Company
maintains a sales service center in Stockton, California.  The Company is
currently certified or approved by 38 states to provide environmental analyses
and is also licensed by the Nuclear Regulatory Commission (NRC) to handle and
analyze "mixed wastes" that contain radioactive as well as chemical and
biological materials.  Additionally, the Company has a laboratory in Auburn,
Alabama, certified by the American Industrial Hygiene Association (AIHA).

CONSTRUCTION AND REMEDIATION

       Consistent with the Company's strategy of providing complete solutions
to its clients' problems, the Company provides remediation and construction
services which can implement the solutions designed by its consulting and
engineering group, or designed by others.  The Company also provides hazardous
waste cleanup; landfill design and construction; water management systems;
wastewater system construction and operation; decommissioning and demolition of
facilities and process systems; storage tank management; and on-site thermal
treatment systems.

       The Company has designed and constructed a patented mobile
low-temperature thermal desorption system (LT(3)(r)). The LT(3) is designed for
stripping volatile organic compounds (VOCs) from soil. The contaminated soils
are heated to vaporize moisture and VOCs. The resultant clean soil is then
suitable for use as on-site backfill.  The Company also has designed and
constructed two high-temperature transportable thermal processing systems, the
"TIS-5" and the "TIS-20."  These systems treat contaminated soils by a thermal
process and the clean soil is then suitable for use as on-site backfill.  The
TIS-5 is permitted by the U. S. Environmental Protection Agency (EPA) under
applicable Toxic Substance Control Act of 1976 (TSCA) regulations to burn
certain hazardous materials and is operated in accordance with those permit
requirements.  Additional operating approvals are occasionally required and
obtained from state and local authorities.

       Transportable thermal incineration technology has recently come under
the same legislative and regulatory pressures as fixed unit incineration
technology.  In May 1994, EPA issued a new policy which required additional
studies to be conducted before thermal incineration technology could be
selected as the remedy at a Superfund site.  This policy was applied
retroactively to sites where thermal incineration technologies were already
selected.  The impact on the Company's thermal business is expected to be
significant in the United States.   The Company has been exploring alternative
uses for its thermal units in the international markets should regulatory and
legislative action prevent their use at domestic remediation sites.  During
1994 and 1995, the Company was scheduled to incinerate soils at two remediation
sites, but both  contracts wereas  terminated.  At one site, and additional
studies are ongoing to determine an appropriate technology, which may include
incineration.

                            CUSTOMERS AND MARKETING

       The Company's marketing strategy emphasizes its ability to offer a broad
range of specialized services designed to meet the needs of its clients in a
timely and cost-efficient manner.  The Company has the capability to undertake
not only small tasks requiring a few professionals, but also the management,
staffing, design, and implementation of major projects that last for several
years and involve many employees in several geographic locations.

       The Company's marketing efforts are directed from regional offices
nationwide to three client sectors: private industry; state and local
governments; and the federal government.  Most new contracts are acquired by
senior technical and management professionals.  These senior professionals are
responsible for directing contract projects, monitoring quality assurance, and
integrating the delivery of the Company's services.  They also develop and
maintain long-term working relationships with clients' management.  The Company
participates in industrial trade shows and technical conferences concerning
environmental and health and safety issues, and sponsors related technical
seminars.

FEDERAL

       In the federal sector, the Company performs contracts for the Department
of Energy (DOE), the Environmental Protection Agency (EPA) and the Department
of Defense (DOD), as well as for other federal agencies. The Company develops
comprehensive waste management and remediation programs at many priority sites
throughout the country.

       The Company derived 54%, 54%, and 57% of its consolidated gross revenues

</TABLE>

       The Company is a major provider of services to the federal government
and thus is subject to audit with respect to costs and fees charged to the
federal government.  Revenues associated with federal overhead rates under
government cost reimbursable contracts are adjusted when variances are
determined on at least an annual basis.  Provisions for losses on contracts are
recorded when they are identified.  As a major government contractor, the
Company is required to comply with numerous, complex laws and regulations; the
failure to comply with which can give rise to sanctions or liabilities.  The
Company is involved in U.S. government investigations and audits from time to
time in connection with the services it provides to the federal government and
to ascertain compliance with government contracting





                                       6

requirements. Loss or reduction in business with the federal government could
have a materially adverse affect on the Company's operations.

INDUSTRIAL

       The Company provides a full range of services for industrial clients.
In addition to complying with regulatory requirements, companies are
recognizing that the environmental impact must be considered from the inception
of a product, throughout its use and final disposal.  Corporate clients, which
range from small business concerns to Fortune 500 companies, are offered a wide
range of consulting and engineering, analytical, and construction and
remediation services.  Market segments served include automotive; chemicals and
allied products; waste management; petroleum; forest products; utilities;
electronics; and legal and financial.

STATE AND LOCAL GOVERNMENT

       The Company renders environmental consulting and infrastructure-related
activities to many state and local governments and agencies.  A growing number
of cities, regional authorities, and state governments are instituting
long-range programs to update essential facilities.  Because these projects
require comprehensive environmental planning and engineering, they will
continue to be an important business component.  Typical projects include the
design of water supply and wastewater systems; solid waste management; asbestos
management; computer-based geographic mapping; and landfill design.

                                  COMPETITION

       The environmental and health and safety markets are very competitive and
require highly skilled, experienced technical and management personnel, and
sophisticated technological equipment requiring substantial capital investment.
Competition is based on, among other items, reputation, quality of service,
price, expertise, and local presence.  In each of its specific service areas,
the Company competes with many engineering and consulting firms that are both
larger and smaller than the Company, although no firm currently dominates any
significant portion of those service areas.  Some of these competitors have
greater financial resources than the Company.  The Company believes it is one
of only a few companies that offer a full range of services for solving complex
environmental and health and safety concerns.

                             PATENTS AND TECHNOLOGY

       The Company owns six patents on remediation technologies and has filed
additional patent applications.  The Company also claims copyright and trade
secret protection on certain of its computer software, publications, and
technologies. The company does not believe that such patents and copyrights are
a material factor in its business.

                                    BACKLOG

       The Company's net contract backlog (excluding estimated project expenses
that are directly passed through to customers) was approximately $112.7 million
and $109.7 million at December 31, 1994 and 1995, respectively.  Additionally,
the Company derives revenues from open order contracts and from





                                       7
<PAGE>   9
activities related to emergency responses.  As work assignments are approved
and funded, the Company includes these amounts in the net contract backlog.  As
is customary in the industry, contracts are subject to cancellation by the
customer, changes in scope of work, and delays in project startup.   The
Company anticipates that the majority of its backlog will be realized in the
current fiscal year.

                       POTENTIAL LIABILITY AND INSURANCE

       A substantial portion of the Company's gross revenues is derived from
work involving hazardous materials, toxic wastes, and other pollutants.  Such
efforts frequently entail significant risks of liability to the Company for
environmental damage, personal injury, and fines and costs imposed by
regulatory agencies.  In addition, a substantial number of the Company's
contracts require indemnification of a client for performance claims, damages
or losses incurred during the performance of the Company's operations.

       The Company has attempted to insure against liabilities it may incur in
connection with the conduct of it's business. The Company has obtained coverage
with commercial carriers to insure against pollution liability claims.
Although this insurance covers many of the Company's environmental exposures,
there are instances where project- specific pollution insurance policies are
necessary.  The Company will continue to evaluate exposures associated with
each project to determine if additional coverage is necessary.  The Company
continues to be partially self-insured through its subsidiary, Cardinal
Indemnity Company of North America (Cardinal), a wholly-owned insurance
company.  Cardinal provides professional liability and pollution coverage for
deductible amounts of the commercial insurance coverage.

       The insurance carried by the Company may not be sufficient to cover all
claims that may arise, and while insurance carriers may not continue to make
coverage available to the Company, management believes it has provided an
adequate level of insurance.

       The Company has also attempted to contractually protect itself through
agreements with its clients to limit its liability and indemnify the Company,
although the Company has not always been successful in obtaining such
agreements.  Most of the Company's contracts with EPA involving Superfund
monies, the contract with the DOE's Office of Civilian Radioactive Waste
Management (OCRWM), and some state contracts that employ federal Superfund
dollars contain provisions whereby the respective governmental agency agrees to
indemnify the Company for third-party claims to the extent that such claims are
not covered by insurance and appropriated funds are available, although the
Company does not receive any assurance that any such appropriated funds will be
made available.  EPA has issued Final Response Action Contractor
Indemnification Guidance (the Indemnification Guidance) applicable to contracts
signed on or after October 16, 1986, the terms of which limit EPA's contractor
indemnification under certain Superfund contracts retroactively to 1986 and
prospectively, under certain circumstances.  The Indemnification Guidance
states that future contracts will not provide for indemnification unless EPA is
unable to obtain responsible, competitive proposals without such an
indemnification.

       The Company has also developed and implemented a quality assurance
program and a health and safety program.  These programs establish certain
minimum requirements for all project work and require the development of
project quality assurance plans and health and safety plans.  The objective of
the quality assurance program is to provide additional assurance that project
performance is of appropriate quality for the project requirements.  The
objective of the health and safety program is to protect project





                                       8
<PAGE>   10
personnel from exposure to hazardous substances and situations.  The scope of
both programs includes the establishment of policy and procedures, staff
training and operational review and audit.

       The Company and its employees are subject to various state, local, and
federal licenses, laws and regulations, and believes that it is in substantial
compliance with those requirements.

                                   PERSONNEL

       As of December 31, 1995, the Company employed approximately 2,650
employees, many of whom had advanced degrees in a variety of technical
disciplines.  Of these, 65 employees held doctorates, 465 held master's
degrees, 188 were registered professional engineers, and 27 were diplomates of
the American Academy of Environmental Engineers.  The Company's ability to
remain competitive will depend on its ability to attract and retain qualified
personnel.

                                   REGULATION

       Demand for the Company's services is principally driven by laws and
regulations, the reauthorization, modification or elimination of which could
significantly affect the Company's business.  The reauthorization of several
major federal environmental laws that have a significant impact on the work of
the Company remains on the agenda of the 104th Congress.  These include the
statutes that:

         - Protect the chemical, physical and biological integrity of water in
           the United States (the Clean Water Act of 1977 and associated laws);

         - Regulate the handling of hazardous waste and mandate state oversight
           of solid waste (the Resource Conservation and Recovery Act of 1976);
           and,

         - Regulate the identification, remediation and accountability for
           hazardous waste sites (the Superfund Amendments and Reauthorization
           Act of 1986).

       In addition, administrative regulations mandated by the 1990 amendments
to the Clean Air Act are likely to play a significant role in the Company's
services to its industrial clients in the areas of emission and ambient air
monitoring, air quality modeling and permitting, and assistance with compliance
certification.

       The principal federal laws that affect the Company's business are:

       THE COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION, AND LIABILITY
ACT OF 1980 (CERCLA OR SUPERFUND) AND SUPERFUND AMENDMENTS AND REAUTHORIZATION
ACT (SARA) OF 1986:  CERCLA addresses past waste disposal practices by
providing means for identifying and remediating hazardous waste sites.  The law
authorizes EPA to compel responsible parties to remediate abandoned sites.
Where initial enforcement actions would result in lengthy delays, or where
responsible parties cannot readily be identified, CERCLA authorizes funds for
cleanups.  Congress enacted SARA in 1986 to amend CERCLA and reauthorize
Superfund.  SARA strengthens EPA's authority to conduct short- and long-term
enforcement, and expands state involvement in the cleanup process.  SARA also
expands EPA's commitment to research and development, training, health
assessments and public participation.





                                       9
<PAGE>   11
Sites considered to be most in need of remediation are ranked on EPA's National
Priorities List (NPL).  By January 1996, some 1,230 federal and nonfederal
sites were listed or proposed for the NPL, and some 13,000 other hazardous
waste sites remained on the CERCLA inventory of potential trouble spots.

       THE CLEAN WATER ACT (CWA):  Amended in February 1987, the CWA authorized
$18 billion in federal revolving loan funds through 1994 for construction
grants and startup money to build wastewater treatment plants. Additional funds
were appropriated for fiscal years 1995 and 1996.  The Company believes that
the CWA is accelerating the market for the municipal wastewater treatment plant
design and construction services provided by the Company.  Controls imposed by
the CWA on toxic effluents also are stimulating industrial expenditures.

       THE RESOURCE CONSERVATION AND RECOVERY ACT OF 1976 (RCRA):  RCRA
controls the present and future management of newly generated hazardous wastes
by mandating that private industry - generators, transporters and disposers -
monitor and regulate their disposal of such wastes.  As a result of the growing
emphasis on the minimization of industrial process wastes, the increasing
shortage of hazardous waste management facilities, and the considerable costs
associated with disposal, RCRA will continue to be a key regulatory program.
The Company believes that responding to the needs of industry under RCRA will
continue to comprise a growing part of its business.

       THE CLEAN AIR ACT (CAA) AND CLEAN AIR ACT AMENDMENTS (CAAA):  The CAAA
of 1990 charged EPA with promulgating more than 400 regulations and developing
guidelines and procedures in the ensuing 10 years.   The sweeping provisions of
the CAAA are designed to diminish three major threats to the environment:  acid
rain, urban air pollution, and air toxic emissions.  The revisions also
establish a national permit program and a stronger enforcement program to make
the CAA easier to monitor and ensure compliance.  The CAA and the CAAA should
continue to increase the Company's activities in emission and ambient air
monitoring, air quality modeling and permitting assistance to its industrial
clients.  Compliance certification, including the development and
implementation of data management and reporting systems, should expand the
Company's services to industry.

       The Company believes that in addition to services required by CERCLA,
RCRA, CWA, and CAA, other federal laws will affect demand for the Company's
services in the private and public sectors.  These include the Safe Drinking
Water Act, the National Environmental Policy Act, the Nuclear Waste Policy Act,
the Toxic Substances Control Act, the Occupational Safety and Health Act, the
Intermodal Surface Transportation and Efficiency Act, the Federal Facilities
Compliance Act and the Energy Policy Act.

ITEM 2.    PROPERTIES

       The Company's principal offices are located on a 53-acre tract in West
Whiteland Township, Chester County, Pennsylvania, in the suburbs of
Philadelphia, and include five major buildings providing a total of
approximately 150,000 square feet of space.

       The Company also leases an aggregate of approximately 670,000 square
feet of office and laboratory space in offices located in 26 states and the
District of Columbia.  Aggregate lease payments in 1995 were $18.5 million, of
which $8.2 million were subject to direct reimbursement from projects.  These
leases for office and laboratory facilities are generally for 5 years or less.

ITEM 3.    LEGAL PROCEEDINGS

       ATLANTIC RICHFIELD CO. (ARCO) VS. TORGER L. OAAS; MONTANA POLE AND
TREATING CO.; BANK OF MONTANA; RIEDEL ENVIRONMENTAL SERVICES, INC.; ROY F.
WESTON, INC.;  AND BURLINGTON NORTHERN RAILROAD, U.S. DISTRICT COURT FOR THE
DISTRICT OF MONTANA, C.A. NO. CV-90-75-BU-PGH.

       In October 1991, ARCO filed a Complaint in the Montana District Court
against the Company and others alleging that the Company, who worked at the
Montana Pole and Treating site for EPA under the Technical Assistance Team
(TAT) contract in 1985, negligently performed its oversight and other duties
and caused additional environmental damage at the site.  ARCO further alleges
that the Company's activities at the site constitute those of an "operator" of
a "facility" under CERCLA and related state statutes and, therefore, the
Company is jointly, severally, and strictly liable for its share of current and
future costs of evaluation and site cleanup.

       The Company believes that it executed its responsibilities properly at
this site and that it otherwise has good and meritorious defenses to these
allegations and is vigorously defending the action.  EPA has honored its
indemnification obligation under the TAT contract, as to both the Company's
cost to defend and as to any liability.  This indemnification obligation is not
adversely affected by the Indemnification Guidance, because it is based upon a
pre-1986 contract.  (See Item 1. Business - Potential Liability and Insurance.)

       In November 1995, the Company and all other parties to the litigation
reached agreement on the terms of a Consent Decree resolving, among other
things, all claims asserted against the Company in the litigation.  There was
no finding of liability against the Company.  The Consent Decree will be filed
with the Court and then published for comment by the public. After reviewing
the comments, EPA is expected to file the Decree with Court for approval.  If
approved, the action against the Company would terminate without further costs
or obligation.

       The Company is subject to certain claims and lawsuits in connection with
work performed in the ordinary course of its business.  In the opinion of
management, all claims currently pending are either adequately covered by
insurance or will not result in a material adverse effect on the financial
position of the Company.

                              ARTICLE II - SEAL

3.       The presence, in person or by proxy, of shareholders entitled to cast
         at least a majority of the votes which all shareholders are entitled
         to cast on a particular matter(s) being considered at a meeting shall
         constitute a quorum at all meetings of the shareholders except as
         otherwise provided by law, by Articles of Incorporation or these

         time is expressly provided therein, but in no event shall a proxy,
         unless coupled with an interest, be voted on after three years from
         the date of its execution.  Shareholders shall not have the right to
         vote cumulatively in the election of directors.  Upon demand made by a
         shareholder at any election for directors before the voting begins,
         the election shall be by ballot.  No share shall be voted at any
         meeting upon which any installment is due and unpaid.  The original
         share ledger or transfer book, or a duplicate thereof kept in this
         Commonwealth, shall be prima facie evidence of the right of the person
         named therein to vote thereon.

5.       Written notice of the annual meeting shall be mailed to each
         shareholder entitled to vote thereat, at such address as appears on
         the books of the Company, at least ten days prior to the meeting.

6.       In advance of any meeting of shareholders, the Board of Directors may
         appoint judges of election, who need not be shareholders, to act at
         such meeting or any adjournment thereof.  If judges of election be not
         so appointed, the chairman of any such meeting may, and on the request
         of any shareholder or his proxy shall, make such appointment at the
         meeting.  The number of judges shall be one or three.  If





                                       2
<PAGE>   3
         appointed at a meeting on the request of one or more shareholders or
         proxies, the majority of shares present and entitled to vote shall
         determine whether one or three judges are to be appointed.  On request
         of the chairman of the meeting, or of any shareholder or his proxy,
         the judges shall make a report in writing of any challenge or question
         or matter determined by them, and execute a certificate of any fact
         found by them.  No person who is a candidate for office shall act as a
         judge.

7.       Special meetings of the shareholders may be called at any time by the
         Chairman of the Board, or the Board of Directors, or the holders of
         not less than one-fifth of all the shares outstanding and entitled to
         vote.  At any time, upon written request of any person entitled to
         call a special meeting, it shall be the duty of the Secretary to call
         a special meeting of the shareholders, to be held at such time as the
         Secretary may fix, not less than ten nor more than sixty days after
         receipt of the request.

8.       Business transacted at all special meetings shall be confined to the
         objects stated in the call and matters germane thereto.

9.       Written notice of a special meeting of shareholders stating the time
         and place and object thereof, shall be mailed, postage prepaid, to
         each shareholder entitled to vote thereat at such address as appears
         on the books of the Company, at least ten days before such meeting,
         unless a greater period of notice is required by statute in a
         particular case.

10.      The officer or agent having charge of the transfer books shall make,
         at least five days before each meeting of shareholders, a complete
         list of the shareholders entitled to vote at the meeting, arranged in
         alphabetical order, with the address of and the number of shares held
         by each, which list shall be subject to inspection by any shareholder
         at any time during usual business hours.  Such list shall also be
         produced and kept open at the time and place of the meeting, and shall
         be subject to the inspection of any shareholder during the whole time
         of the meeting. The original share ledger or transfer book, or a
         duplicate thereof kept in this Commonwealth, shall be prima facie
         evidence as to who are the shareholders entitled to examine such list
         or share ledger or transfer book, or to vote in person or by proxy, at
         any meeting or shareholders.

         who need not be residents of the Commonwealth of Pennsylvania or
         shareholders of the Company.  Subject to the preceding sentence and
         the provisions of applicable law, the Board of Directors shall have
         the authority to (i) determine the number of directors to constitute
         the Board and (ii) if such number is increased between annual meetings
         of the shareholders, fill the vacancy or vacancies thereby created.
         Except as otherwise hereinbefore provided with respect to interim
         vacancies, directors shall be elected by plurality vote at the annual
         meeting of shareholders, and each director shall be elected for a term
         extending until the next following annual meeting of shareholders and,
         except in the event of death, resignation or removal, shall serve
         until such director's successor shall be elected and shall qualify.

2.       In addition to the powers and authorities by these By-Laws expressly
         conferred upon them, the Board may exercise all such powers of the
         Company and do all such lawful acts and things as are not by statute
         or by the Articles or by these By-Laws directed or required to be
         exercised or done by the shareholders.

3.       The meetings of the Board of Directors may be held at such place
         within this Commonwealth, or elsewhere, as a majority of the directors
         may from time to time appoint, or as may be designated in the notice
         calling the meeting.

4.       Each newly-elected Board may meet at such place and time as shall be
         fixed by the shareholders at the meeting at which such directors are
         elected, and no notice shall be necessary to the newly elected
         directors in order to legally constitute the meeting, or they may meet
         at such place an time as may be fixed by the consent in writing of all
         the directors.

5.       Regular meetings of the Board may be held without notice at such time
         and place as shall be determined by the Board.

6.       Special meetings of the Board may be called by the Chairman of the
         Board on one day's notice to each director, either personally or by
         mail or by telegram; special meetings shall be called by the President
         or Secretary in like manner on like notice on the written request of
         two directors.

7.       A majority of the directors in office shall be necessary to constitute
         a quorum for the transaction of business, and the acts of a majority
         of the directors present at a meeting at which a quorum is present
         shall be the acts of the Board of Directors.  If all the directors
         shall severally or collectively consent in writing to any action to be
         taken by the Company, such action shall be as valid corporate action
         as though it had been authorized at a meeting of the Board of
         Directors.

8.       Directors as such shall not receive any stated salary for their
         services, but by resolution of the Board, a fixed sum and expenses of
         attendance, if any, may be allowed for attendance at each regular or
         special meeting of the Board, or committees of the Board if such
         Committee meetings are held on days other than Regular or Special
         Board meetings, PROVIDED that nothing herein contained shall be
         construed to preclude any director from serving the Company in any
         other capacity and receiving compensation therefor.

9.       The Board of Directors may elect an Executive Committee consisting of
         the Chairman of the Board and such additional directors as may from
         time to time be designated as members thereof by resolution of the
         Board of Directors, which Committee shall have, between meetings of
         the Board, all of the powers of the Board except such as may not be
         lawfully delegated to a committee.

         In addition, the Board of Directors may form other committees of
         service of the Board.  Each committee member shall be a member of the
         Board, and nominated by the Chairman.

10.      One or more directors may participate in a meeting of the Board or of
         a committee of the Board by means of conference telephone or similar
         communications equipment by means of which all persons participating
         in the meeting can hear each other, and any director so participating
         in a meeting shall be deemed to be present at the meeting for all
         purposes.

                            ARTICLE V - OFFICERS

         of Directors may also choose one or more Vice Chairmen and Vice
         Presidents and such other officers and agents as it deems necessary,
         who shall hold their offices for such terms and shall have such
         authority and shall perform such duties as from time to time shall be

         same person, except the combination of the Offices of President and
         Secretary.  It shall not be necessary for the officers to be
         directors.

2.       The salaries of all officers and agents of the Company shall be fixed
         by the Board of Directors.

         Directors whenever, in their judgement, the best interests of the
         Company will be served thereby.

4.       The Chairman of the Board shall preside at all meetings of the
         shareholders and directors.  The Vice Chairman (or, if more than one,

         kept for that purpose; and shall perform like duties for all
         committees of the Board of Directors when required.  He shall give, or
         cause to be given, notice of all meetings of the shareholders and of
         the Board of Directors, and shall perform such other duties as may be

                                       6
<PAGE>   7
         liability.  He shall analyze financial records to forecast the future

         President of the Company, shall be appointed by the Board, and shall
         have general and active management of the business of the Company and
         shall see that all orders and resolutions of the Board are carried
         into effect, subject however to the right of the directors to delegate
         any specific powers to any other officer or officers of the Company.
         He shall be an ex-officio member of all committees, and shall have the
         general powers and duties of supervision and management usually vested
         in the Chief Executive Officer of a Company.

         Officer or the Board of Directors.

11.      The Chief Financial Officer shall exercise such responsibilities as
         may from time to time be assigned to him by the Chief Executive
         Officer or the Board of Directors, including the preparation of
         reports which outline the Company's financial position in areas of
         income, expenses, and earnings, based on past, present and future

         the Board of Directors, shall direct the payment of dividends on the
         stock of the Company.

                                       7
<PAGE>   8
         any reason, the Board of Directors may choose a successor or
         successors, who shall hold office for the unexpired term in respect of
         which such vacancy occurred.

2.       Vacancies in the Board of Directors shall be filled by a majority of
         the remaining members of the Board though less than a quorum, and each
         person so elected shall be a director until his successor is elected
         by the shareholders, who may make such election at the next annual
         meeting of the shareholders or at any special meeting duly called for
         that purpose and held prior thereto.

                       ARTICLE VII - CORPORATE RECORDS

         original or duplicate record of the proceedings of the shareholders
         and of the directors, and the original or a copy of its By-Laws,
         including all amendments or alterations thereto to date, certified by
         the Secretary of the Company.  An original or duplicate share register
         shall also be kept at the registered office, or at the office of a
         transfer agent or registrar within the Commonwealth, giving the names
         of the shareholders in alphabetical order, and showing their
         respective addresses, the number and classes of shares held by each,
         the number and date of certificates issued for the shares, and the
         number and date of cancellation of every certificate surrendered for
         cancellation.

2.       Every shareholder shall have a right to examine, in person or by agent
         or attorney, at any reasonable time or times, for any reasonable
         purpose, the share register, books or records of account, and records
         of the proceedings of the shareholders and directors, and make
         extracts therefrom.

                        ARTICLE VIII - CAPITAL STOCK

1.       The share certificates of the Company shall be numbered and registered
         in the share ledger and transfer books of the Company, as they are
         issued.  They shall be signed by the Chairman of the Board or
         President and the Secretary or an Assistant Secretary and shall bear
         the corporate seal.

2.       Transfers of shares shall be made on the books of the Company upon
         surrender of the certificates therefor, endorsed by the person named
         in the certificate or by attorney, lawfully constituted in writing.

         8 of the Uniform Commercial Code, approved the sixth day of April, One

         Thousand Nine Hundred Fifty-Three (Act No. 1), and its amendments and
         supplements.





                                       9
<PAGE>   10
3.       The Board of Directors may fix a time, not more than seventy days,
         prior to the date of any meeting of shareholders, or the date fixed
         for the payment of any dividend or distribution, or the date for the
         allotment of rights, or the date when any change or conversion or
         exchange of shares will be made or go into effect, as a record date
         for the determination of the shareholders entitled to notice of, and
         to vote at, any such meeting, or entitled to receive payment of any
         such dividend or distributions, or to receive any such allotment of
         rights, or to exercise the rights in respect to any such change,
         conversion, or exchange of shares.  In such case, only such
         shareholders as shall be shareholders of record on the date so fixed
         shall be entitled to notice of, and to vote at, such meeting, or to
         receive payment of such dividend, or to receive such allotment of
         rights, or to exercise such rights as the case may be, notwithstanding
         any transfer of any shares on the books of the Company after any
         record date fixed as aforesaid.  The Board of Directors may close the
         books of the Company against transfers of shares during the whole or
         any part of such period, and in such case, written or printed notice
         thereof shall be mailed at least ten days before the closing thereof
         to each shareholder of record at the address appearing on the records
         of the Company or supplied by him to the Company for the purpose of
         notice.  While the stock transfer books of the Company are closed, no
         transfer of shares will be made thereon.  If no record date if fixed
         for the determination of shareholders entitled to receive notice of,
         or vote at, a shareholders meeting, transfers of shares which are
         transferred on the books of the Company within ten days next preceding
         the date of such meeting shall not be entitled to notice of, or vote
         at, such meeting.

4.       Any person claiming a share certificate to be lost or destroyed shall
         make an affidavit or affirmation of that fact and advertise the same
         in such manner as the Board of Directors may require, and shall give
         the Company a bond of indemnity with sufficient surety to protect the
         Company or any person injured by the issue of a new certificate from
         any liability or expense which it or they may incur by reason of the
         original certificate remaining outstanding, whereupon a new
         certificate may be issued by the same tenor and for the same number of
         shares as the one alleged to be lost or destroyed, but always subject
         to the approval of the Board of Directors.

5.       Subject to the provisions of the statutes, the Board of Directors may
         declare any pay dividends upon the outstanding shares of the Company
         out of its surplus from time to time and to such extent as they may
         deem advisable, in cash, in property, or in shares of the Company.





                                       10
<PAGE>   11
6.       Before payment of any dividend there may be set aside out of the net
         profits of the Company such sums as the directors, from time to time,
         in their absolute discretion, think proper as a reserve fund to meet
         contingencies, or for equalizing dividends, or for repairing or
         maintaining any property of the Company, or for such other purpose as
         the directors shall think conducive to the interest of the Company,
         and the directors may abolish any such reserve in the manner in which
         it was created.

                    ARTICLE IX - MISCELLANEOUS PROVISIONS

1.       All checks or demands for money and notes of the Company shall be
         signed by such officer or officers as the Board of Directors may from
         time to time designate.

2.       The fiscal year shall begin the 1st day of January each year.

3.       Whenever written notice is required to be given to any person, it may
         be given to such person, either personally or by sending a copy
         thereof through the mail, or by telegram, charges prepaid, to his
         address appearing on the books of the Company, or supplied by him to
         the Company for the purpose of notice.  If the notice is sent by mail
         or by telegraph, it shall be deemed to have been given to the person
         entitled thereto when deposited in the United States mail or with a
         telegraph office for transmission to such person.  Such notice shall
         specify the place, day, and hour of the meeting and, in the case of a
         special meeting, the general nature of the business to be transacted.

4.       Whenever any written notice is required by statute, or by the Articles
         or By-Laws of this Company, a waiver thereof in writing, signed by the
         person or persons entitled to such notice, whether before or after the
         time stated therein, shall be deemed equivalent to the giving of such
         notice.  Except in the case of a special meeting, neither the business
         to be transacted at, nor the purpose of the meeting need be specified
         in the waiver of notice of such meeting.  Attendance of a person,
         either in person or by proxy, at any meeting shall constitute a waiver
         of notice of such meeting, except where a person attends a meeting for
         the express purpose of objecting to the transaction of any business
         because the meeting was not lawfully called or convened.

5.       The Company shall indemnify its directors, officers, employees, and
         agents to the full extent permitted by Section 410 of the Business
         Corporation Law.

                        ARTICLE X - ANNUAL STATEMENT

1.       The Chairman of the Board and Board of Directors shall present at each
         annual meeting a full and complete statement of the business and
         affairs of the Company for the preceding year.  Such statement shall
         be prepared and presented in whatever manner the Board of Directors
         shall deem advisable and need not be verified by a certified public
         accountant.

                           ARTICLE XI - AMENDMENTS

1.       These By-Laws may be altered, amended, or repealed by the affirmative
         vote of a majority of the shares issued and outstanding and entitled

                       ARTICLE XIII - INDEMNIFICATION

1.       The Company shall indemnify to the extent not prohibited by applicable
         law, any person who was or is a party or is threatened to be made a
         party to any threatened, pending or completed action, suit or
         proceeding, whether civil, criminal, administrative or investigative,
         by reason of the fact that he is or was a director, officer, employee
         or agent of the Company or is or was serving at the request of the
         Company as a director, officer, employee or agent of another
         corporation, partnership, joint venture, trust or other enterprise,
         including an employee benefit plan, against expenses (including
         attorneys' fees), judgments, fines and amounts paid in settlement
         actually and reasonable incurred by him in connection with such
         action, suit or proceeding, whether or not the indemnified liability
         arises or arose from any threatened, pending or completed action by or
         in the right of the Company.  The Board of Directors may, and on
         request of any such person shall be required to, determine in each
         case whether the applicable standards in the Pennsylvania Directors'
         Liability Act or any other applicable statute have been met, or such
         determination shall be made by independent legal counsel if the Board
         so directs or if the Board is not empowered by law to make such
         determination.  If there has been a change in control of the Company
         between (1) the time of the action or failure to act giving rise to
         the claim for indemnification and (2) the time such claim is made at
         the option of the person seeking indemnification the permissibility of
         indemnification shall be determined by special legal counsel selected
         jointly by the Company and the person seeking indemnification.  The
         fees and expenses of such counsel shall be paid by the Company.  The
         obligations of the Company to indemnify a director, officer, employee
         or agent under this Article XIII, including the duty to advance
         expenses, shall be a contract between the Company and such person, and
         no modification or repeal of any provision of this Article XIII shall
         affect, to the detriment of the Director, officer, employee or agent
         such obligations of the Company in connection with a claim based on
         any act or failure to act occurring before such modification or
         repeal.

2.       Expenses incurred by an officer, director, employee or agent of the
         Company in defending a civil or criminal action, suit or proceeding
         shall be paid by the Company in advance of the final disposition of
         such action, suit or proceeding upon receipt of an undertaking by or
         on behalf of the director, officer, employee or agent to repay such
         amount if it shall ultimately be determined that he is not entitled to
         be indemnified by the Company.

3.       The indemnification and advancement of expenses provided by this
         Article XIII shall not be deemed exclusive of any other right to which
         one indemnified may be entitled under any agreement, vote of
         shareholders or otherwise, both as to action in his official capacity
         and as to action in another capacity while holding such office, and
         shall inure to the benefit of the heirs, executors and administrators
         of any such person.

4.       The Board of Directors shall have the power to (a) authorize the
         Company to purchase and maintain, at the Company's expense, insurance
         on behalf of the Company and others to the extent that power to do so
         has been or may be granted by statute, (b) create any fund of any
         nature, whether or not under the control of a trustee, or otherwise
         secure any of its indemnification obligations and (c) give other
         indemnification to the extent not prohibited by statute.

                                                                   EXHIBIT 10.10

                              ROY F. WESTON, INC.


                              SEVERANCE AGREEMENT

         Severance Agreement ("Agreement") made effective March 1, 1996 between
Roy F. Weston, Inc., a Pennsylvania corporation, ("Weston") and A. Frederick
Thompson, Jr. ("Thompson").

                                   BACKGROUND

         Thompson currently is an employee of Weston.  He resigned as Chairman
of Weston's Board of Directors effective March 1, 1996.

         Weston and Thompson have a written agreement with respect to
Thompson's employment ("Employment Agreement"), which is attached hereto as
Exhibit A.

         Weston and Thompson have entered into a separate Supplemental
Retirement Agreement ("Retirement Agreement") made as of December 31, 1989,
which is attached hereto as Exhibit B.

         Weston and Thompson agree that it would serve the best interests of
each to provide Thompson with certain additional benefits in consideration of
Thompson's agreement to terminate his employment with Weston and in
consideration of his resignation as the Chairman of Weston's Board of
Directors.

                                   AGREEMENT

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained herein and intending to be legally bound
hereby, the parties hereto agree as follows:

                 1.       Resignation Date.  Effective April 1, 1996, Thompson
shall resign and no longer be a Weston employee.
<PAGE>   2
                 2.       Severance Benefits and Payment Conditions.  In
consideration of Thompson's resignation and Thompson's agreements  and
undertakings under Section 3 hereof, Thompson shall receive the severance
benefits set forth herein provided Thompson satisfies each of the requirements
of Section 3 hereof.  Thompson's entitlements under the Retirement Agreement
and any employee benefit plan, including Weston's vacation plan, applicable to
a class of Weston employees which includes Thompson shall be as provided for
therein without regard to this Agreement, except as expressly provided in this
Section.  The severance benefits under this Agreement are as set forth below:

                          (a)  Salary Continuation.  Weston shall pay  Thompson
$23,715 per month for 24 months, commencing with April of 1996 and ending with
March of 1998.  If Thompson dies before the last monthly payment, the remaining
payments shall be paid to his estate.

                          (b)     Salary-At-Risk.  Weston shall pay Thompson
the amount he earned under its Salary-At-Risk Program for the calendar quarter
ended March 31, 1996.  Weston shall make the payment on or about the date
Weston makes Salary-At-Risk payments to participating employees.

                          (c)     Retirement Agreement.  For purposes of the
Retirement Agreement, Thompson shall be treated as having a vested interest in
his retirement benefit as if he remained a Weston employee through his 65th
birthday, which is $91,000 per year for 15 years, payable in monthly
installments of $7,583.33

                                      2
<PAGE>   3
for 180 months beginning with the first month following Thompson's 65th
birthday.  If Thompson dies after benefits commence, the remainder of the
payments shall be made in accordance with the Retirement Agreement.  If
Thompson dies before benefits commence, his designated beneficiary shall be
paid the death benefit provided for in the Retirement Agreement according to
its terms.   Thompson shall have the right to elect that payments under the
Retirement Agreement begin with any month following his 60th birthday, in which
case the benefit amount payable for the 180 month period shall be reduced as
provided under the Retirement Agreement.  All other terms of the Retirement
Agreement shall remain effective, except as modified in this Severance
Agreement.

                          (d)     Medical Benefits.  Weston shall provide
medical, dental and prescription plan benefits for Thompson on the same basis
as in effect for active employees for 24 months or until he sooner elects that
such coverages cease.  After such 24-month period, Thompson may elect
continuation coverage completely at his own expense as provided by law.

                          (e)     Outplacement.  Weston shall provide Thompson
outplacement services at Weston's expense at the level presently in effect for
executive employees.

                 3.       Thompson's Agreements and Undertakings.

                          (a)     Cooperation Requirement.  Thompson shall
provide Weston such information pertaining to his employment with Weston as he
may have and assist Weston to transfer his duties to





                                       3
<PAGE>   4
such successor or successors as Weston may designate.  Weston shall reimburse
Thompson for all reasonable expenses he incurs in fulfilling his obligations
under the preceding sentence.

                          (b)     Non-Competition Requirement.  Weston's
obligation to make payments or provide benefits under Section 2, including all
payments under the Retirement Agreement, shall terminate and Weston shall have
the right to restitution of payments made or the cost of benefits provided if
Thompson, without Weston's prior written approval, either directly or
indirectly, for his own account or for the account of another person or entity,
for a period of two years from and after the date his employment terminates:

                                  (i)      acquires or holds a significant
financial interest in any competitor of Weston or any "Weston affiliate" (as
defined below);

                                  (ii)     competes with Weston or any "Weston
affiliate" in soliciting any business from any person or entity that was at any
time during the two years immediately preceding April 1, 1996 a client of
Weston or any "Weston affiliate" or potential client as to whom Weston or any
"Weston affiliate" had rendered a significant volume of service or had a
significant amount of direct business contact for the purpose of soliciting
future business; or

                                  (iii) renders services to any competitor of
Weston or any "Weston affiliate", if such services are (A) similar in nature
(in whole or in part) to services Thompson





                                       4
<PAGE>   5
rendered to Weston or any "Weston affiliate" at any time during the two years
immediately preceding April 1, 1996.

For purposes of this Section, the term "Weston affiliate" shall mean any
business in which Weston owns directly or indirectly at least 50% of the equity
interests or 50% of the profit interests. This Section supersedes the
non-competition and non-solicitation provisions of the Employment Agreement.
This Section replaces the Non-Competition Provision of the Retirement Agreement
until April 1, 1998, at which time such provision becomes effective to and
including March 31, 1999 with respect to benefits provided under the Retirement
Agreement as modified by this Agreement.

                          (c)     Release.  Thompson shall deliver a release 
to Weston in the form attached hereto as Exhibit C.

                 4.       Acceleration Election.  Weston may, at its option, at
any time or from time to time, in its absolute and sole discretion, accelerate
the time and the manner of making any one or more payments required by this
Agreement.

                 5.       Non-Alienation.  None of the rights or payments
contemplated under this Agreement may be sold, given away, assigned,
transferred, pledged, mortgaged, alienated, hypothecated or in any way
encumbered or disposed of by Thompson, or any executor, administrator, heir,
legatee, distributee, relative or any other person or entity, whether or not in
being, claiming under Thompson by virtue of this Agreement, and none of the
rights or benefits contemplated by this Agreement shall be





                                       5
<PAGE>   6
subject to execution, attachment or similar process.  Any sale, gift,
assignment, transfer, pledge, mortgage, alienation, hypothecation or
encumbrance, or other disposition of this Agreement or of such rights or
benefits contrary to the foregoing provisions, or the levy or any attachment or
similar process thereon, shall be null and void and without effect.

                 6.       Taxes.  Weston shall withhold from payments to
Thompson and remit to the appropriate government agencies such payroll taxes
and income withholding as Weston determines is or may be necessary under
applicable law with respect to amounts paid under this Agreement.

                 7.       General Obligation.  The rights and benefits of
Thompson hereunder shall be solely those of an unsecured creditor of Weston.

                 8.       Waiver of Breach.  Weston's failure to insist upon
strict compliance with any of the terms, covenants or conditions hereof shall
not be deemed a waiver of such term, covenant or condition, nor shall Weston's
waiver or relinquishment of any right or power hereunder at any one or more
times be deemed a waiver or relinquishment of such right or power at any other
time or times.

                 9.       Modification.  This Agreement shall not be modified
or amended except by written instrument duly executed by Weston and Thompson.

                 10.      Severability.  If any clause, sentence, paragraph,
section, or part of this Agreement shall be held by any court of competent
jurisdiction to be invalid, such judgment shall not affect, impair or
invalidate any of the other parts hereof.

                 11.      Notices.  Any notice required or permitted to be
given under this Agreement shall be sufficient if in writing and either
hand-delivered to the addressee or sent by registered or certified mail, if to
Thompson, to Thompson's address as shown on Weston's books, and if to Weston,
addressed to the Chairman of Weston's Board of Directors at Weston's principal
business office located at One Weston Way, West Chester, Pennsylvania
19380-1499 or such other address as Weston or Thompson may designate in
writing.

                 12.      Arbitration.  Any controversy or claim arising out of
or relating to this Agreement or the breach thereof shall be settled by
arbitration in the City of Philadelphia in accordance with the rules of the
American Arbitration Association then in effect.  The decision of the
arbitrator shall be final and binding upon the parties, and judgment upon the
decision rendered in such arbitration may be entered in any court having
jurisdiction.

                 13.      Captions.  The captions of the various provisions
shall not be deemed a part of this Agreement and shall not be construed in any
way to limit the contents hereof but are inserted herein only for reference and
for convenience of the parties.

</TABLE>


         The Company incurs a substantial amount of direct project costs, which
are passed through to the Company's clients, resulting principally from the use
of subcontractors on projects. Consequently, the Company measures its operating
performance on the basis of net revenues, which are determined by deducting
such direct project costs from gross revenues. Direct project costs were 33%,
31% and 32% of gross revenues in 1995, 1994 and 1993, respectively.

RESULTS OF OPERATIONS

1995 COMPARED TO 1994

         Net revenues increased 3% to $206,273,000 from $200,304,000 in 1994.
Net revenues from remediation and consulting projects increased 36% and 4%,
respectively.  Partially offsetting these gains was a 19% decline in analytical
services net revenues due to downward pricing pressures which have impacted the
analytical services industry. Net revenues from federal program management
services, which are large government projects with dedicated work forces,
declined 6%, as federal agencies reduced funding on certain projects. Federal
budget reductions affecting environmental regulations will likely further
diminish federal program management net revenues.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                           OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS

         The Company had income from operations of $2,623,000 in 1995, compared
to a $730,000 loss from operations in 1994.  The improved operating results
were primarily due to higher net revenues from remediation projects, partially
offset by significantly lower margins for analytical services.  During 1995,
the Company adopted a plan to close one of its laboratory facilities and
recorded a provision of $1,300,000, consisting principally of lease termination
costs and the writedown of leasehold improvements and equipment. The Company
believes efficiencies gained by concentrating its analytical laboratory
services in its remaining two laboratories will reduce fixed costs; however,
the outlook for the analytical services industry continues to be difficult.
Operating results from consulting projects increased slightly in 1995 as a
result of higher personnel utilization.  Margins for consulting work improved
in most areas, but declined in the Western United States.  Operating results
from federal program management services declined from 1994 in an amount
similar to the 1995 revenue shortfall, principally due to reduced program
personnel requirements and utilization.

         The smaller of the Company's two transportable thermal treatment
systems has been idle since mid-1994. The system had been committed to a
contract that was cancelled in late 1994. The Company recorded net revenues of
approximately $1,800,000 in 1995 and $1,520,000 in 1994 in connection with the
settlement of the termination claim. The Company is seeking additional projects
that will use this equipment, but anticipates 1996 treatment system
profitability to be lower than 1995.

         Overall spending for 1995 general and administrative expenses remained
similar to that of the prior year. The Company increased its spending on
quality assurance and strategic planning, while realizing cost savings from
business process efficiencies. The Company is continuing to allocate
significant resources to business development activities.

         Other expenses decreased 76% to $258,000 in 1995 from $1,056,000 in
1994.  Other expenses were reduced by gains of $376,000 and $51,000 realized on
redemption of the Company's 7% Convertible Subordinated Debentures in 1995 and
1994, respectively.  Investment income increased $193,000 in 1995 due primarily
to higher interest rates.  Interest expense decreased $259,000 from 1994 due
primarily to the repurchase of 7% Convertible Subordinated Debentures and
scheduled repayments of its five-year term loan.

1994 COMPARED TO 1993

         Net revenues declined 7% to $200,304,000 from $214,869,000 in 1993.
The Company's consulting projects produced 8% lower net revenues in 1994.  Net
revenues in 1994 from federal program management services declined 5% due to a
decrease in direct labor.  Analytical laboratory services net revenues were 7%
lower than those in 1993 primarily due to continuing downward pricing
pressures.  Net revenues from remediation projects were similar to those in
1993.

         The Company experienced a $730,000 loss from operations in 1994,
compared to operating income of $6,248,000 in 1993.  Operating income in 1993
was reduced by a $2,000,000 charge related to an adverse court decision.  The
decline in operating results was primarily due to decreased net revenues.
Direct salaries and other operating costs declined 4%, primarily due to
selective operating work force reductions.  General and administrative expenses
increased less than 2% in 1994.  Margins for

consulting work were generally lower, except in the Midwestern United States.
Contribution from remediation projects was improved from 1993, which included a
sizable loss on one project.

         Other expenses decreased 52% to $1,056,000 in 1994 from $2,179,000 in
1993.  Other expenses were reduced by gains of $51,000 and $94,000 realized on
redemption of the Company's 7% Convertible Subordinated Debentures in 1994 and
1993, respectively.  Investment income increased $707,000 due to higher average
amounts invested and higher interest rates.  Interest expense decreased
$546,000 from 1993 due primarily to the repurchase of 7% Convertible
Subordinated Debentures and scheduled repayments of a five-year term loan.

         As discussed in Note 9 to the Consolidated Financial Statements, the
Company decreased the discount rate used for its defined benefit pension plans
to 7.25% at December 31, 1995 from 8.50% at December 31, 1994. This discount
rate change is expected to increase the net periodic pension cost charged to
income in 1996 by approximately $500,000 as compared to the 1995 expense of
$2,409,000.

         The Financial Accounting Standards Board has issued Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation," effective for fiscal years beginning after December 15, 1995.
Statement No. 123 allows the recognition of compensation expense for grants  of
stock, stock options and other equity instruments to employees based on fair
value, or, permits continued application of existing accounting rules. The
Company plans to continue to apply existing rules and will disclose the
required proforma net income and earnings per share data. The adoption of
Statement No. 123 will not have an impact on the Company's financial position
or results of operations.

         Management believes that inflationary increases in its operating costs
and expenses can generally be absorbed by increased rates the Company can bill
for its services. To date, inflationary effects have had little impact on the
Company.

LIQUIDITY AND CAPITAL RESOURCES

         Cash and cash equivalents increased $7,235,000 in 1995 to $12,980,000
from $5,745,000 at December 31, 1994. Marketable securities  decreased
$10,179,000 in 1995 to $2,813,000 from $12,992,000 at December 31, 1994.

         Operating activities provided cash of $12,789,000 in 1995 and
$1,121,000 in 1994.  The Company used a portion of its cash flow from
operations to liquidate $5,436,000 and $3,648,000 of short-term and long-term
debt in 1995 and 1994, respectively.

         Net cash investments in property and equipment and other assets were
$9,988,000 in 1995 and $4,858,000 in 1994.  Investments in 1995 included
$2,000,000 for a minority interest in a bioremediation and infrastructure
engineering company, building improvements, computers and other equipment.
Investments in 1994 consisted principally of computers and other equipment. The
Company's capital expenditures are financed primarily through operating cash
flow.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                           OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS

         The Company has a five-year term loan at a 5.85% interest rate, which
is repayable in quarterly installments of $500,000 plus interest through
January 1, 1998.  The Company is required to make annual redemptions of 10% of
its 7% Convertible Subordinated Debentures in the principal amount of
$3,140,000.  The 1996 requirement has been satisfied through repurchases of the
debentures during 1994 and 1995.

         The Company received $1,359,000 in 1995 and $1,623,000 in 1994 from
shares of Series A common stock issued through its Employee Stock Purchase
Plan.  During 1995 and 1994, the Company repurchased 298,400 and 214,705
shares, respectively, of Series A common stock for $1,512,000 and $1,297,000,
respectively. There are no current plans to issue additional stock other than
through the Employee Stock Purchase Plan and the Stock-Based Incentive
Compensation Plan.

                       REPORT OF INDEPENDENT ACCOUNTANTS

Board of Directors and Stockholders
Roy F. Weston, Inc.

         We have audited the accompanying consolidated balance sheets of Roy F.
Weston, Inc. and Subsidiaries as of December 31, 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 December 31, 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, the financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Roy F.
Weston, Inc. and Subsidiaries as of December 31, 1995 and 1994, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1995 in conformity with generally
accepted accounting principles.

                             NOTES TO CONSOLIDATED
                              FINANCIAL STATEMENTS

NOTE 1 - NATURE OF OPERATIONS

         The Company provides environmental services to industry, the federal
government, and state and local government units.  Environmental services
provided include consulting, construction and remediation, analytical
laboratory services and federal program management.  The Company's services are
provided primarily in the United States, although it does undertake projects in
foreign nations.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

         The consolidated financial statements include the accounts of the
Company and its subsidiaries.  All material intercompany accounts and
transactions have been eliminated in consolidation. 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 revenues and expenses during the reporting period.  Actual results
could differ from those estimates.

Cash Equivalents and Investments

         The Company considers all highly liquid investments with a remaining
maturity of three months or less at the time of purchase to be cash
equivalents.  Cash and cash equivalents consist of cash on hand, demand deposit
accounts, and investments in corporate commercial paper and U.S. Government
securities.  Marketable securities are stated at fair value.  Realized gains
and losses are computed based on specific identification.

         Marketable equity and debt securities available for current operations
include investments in corporate commercial paper and U.S. Government debt
securities and are classified as current assets in the accompanying
consolidated balance sheets.  Investments held by the Company's wholly-owned
captive insurance subsidiary include equity and bond mutual funds and are
classified as noncurrent assets in the accompanying consolidated balance
sheets.

Property and Equipment

         Property and equipment are carried at cost.  Depreciation is provided
primarily on the straight-line method over the assets' estimated useful lives
of 10 to 40 years for buildings and improvements and 3 to 10 years for
furniture and equipment.  Leasehold improvements are amortized over the shorter
of the lease period or estimated useful life on the straight-line method.
Property and equipment leased under capital leases are recorded at the lower of
fair market value or the present value of future lease payments.  Property and
equipment under these leases are amortized on a straight-line basis, generally
over the assets' estimated useful lives. When property or equipment is sold or
retired, the cost of the asset and related accumulated depreciation are removed
from the balance sheet and any gain or loss is included in results of
operations.

Goodwill

         Goodwill arising from the excess of purchase price over the underlying
fair value of net assets of acquired companies is amortized on the
straight-line method over a 40-year period.  The Company annually evaluates
whether changes have occurred that would require revision of the remaining
estimated useful life of goodwill.  If such circumstances arise, the Company
uses an estimate of the related operation's income contribution to determine
whether the goodwill is recoverable.

Long-Lived Asset Impairment

         Effective January 1, 1995, the Company adopted 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 provisions of
Statement No. 121 require the Company to review its long-lived assets for
impairment on an exception basis whenever events or changes in circumstances
indicate that the carrying amount of the assets may not be recoverable through
future cash flows. If it is determined that

                      ROY F. WESTON, INC. AND SUBSIDIARIES


an impairment loss has occurred, the loss is recognized in the consolidated
statement of operations. The adoption of Statement No.  121 was not material to
the financial position or results of operations as of and for the year ended
December 31, 1995.

Income Taxes

         The Company provides deferred income taxes on all temporary
differences between the tax and financial reporting bases of its assets and
liabilities.

Contract Revenue Recognition

         The Company's principal business is providing professional engineering
and consulting services under cost-plus-fee, time and materials, and
fixed-price contracts.  Revenues from contracts are recorded on the
percentage-of-completion method of accounting, determined by relating contract
costs incurred to date to total estimated contract costs at completion.
Estimated award fees on certain long-term federal contracts are included in
revenues at the time the amounts can be reasonably determined.  Revenues
associated with U.S. Government indirect rates are adjusted when variances are
determined on at least an annual basis.  Provisions for estimated contract
losses are recorded when identified.

Net Income (Loss) Per Share

         Net income (loss) per share is computed by dividing net income (loss)
by the weighted average number of common shares and Series A common shares
outstanding during the period, including applicable common stock equivalents.
The conversion of subordinated debentures has not been assumed because the
result is anti-dilutive.

NOTE 3 - INVESTMENTS

         Effective January 1, 1994, the Company adopted Statement of Financial
Accounting Standards No. 115, "Accounting for Certain Investments in Debt and
Equity Securities."  Under this statement, the Company's investments are
classified as available-for-sale securities and recorded at current market
value with an offsetting adjustment included in stockholders' equity.

Investments in debt and equity securities at December 31 consisted of the
following:

         The Company does not believe there is any undue credit risk in
connection with its accounts receivable.

         Unbilled costs and estimated earnings can be invoiced upon attaining
certain milestones under fixed-price contracts, completion of federal
government indirect rate audits, final approval of design  plans for
engineering services and completion of construction on certain projects. Billed
and unbilled retentions of $2,484,000 at December 31, 1995 include $443,000,
which is expected to be collected during 1997 and thereafter.


NOTE 5 - LINE-OF-CREDIT AGREEMENT

         The Company has a $45,000,000 unsecured credit facility with a group
of banks to provide cash borrowings and letters of credit that expires in 1997.
Under the terms of the agreement, cash borrowings, which may not exceed
$25,000,000, bear interest at the prime rate or, at the Company's option, other
variable rates.  The Company is subject to a 1/4% annual charge on the unused
portion of the facility.  The agreement requires the Company to maintain
covenants including liquidity, debt to equity, interest coverage, minimum net
worth and fixed charge coverage.  At December 31, 1995, the unused portion of
the unsecured credit facility was $40,098,000.

         The 7% Convertible Subordinated Debentures (the Debentures) were
issued in 1987.  The Debentures are due April 15, 2002 and are convertible into
the Company's Series A common stock at a conversion price of $21.13 per share.
The Company has the option to redeem the Debentures at a redemption price of
100%.

         The Company is required to redeem annually 10% of the principal amount
of the Debentures, so as to retire 80% of the Debentures prior to maturity.
During 1995 and 1994, the Company repurchased $3,000,000 and $1,000,000
principal amount of Debentures, respectively, thus satisfying the 1995 and 1996
redemption requirements.  The gains on redemption of $376,000 and $51,000 in
1995 and 1994, respectively,  have been included in other income in the
consolidated statements of operations.  The Debentures are unsecured and
subordinated to all senior indebtedness.  The costs of issuing the Debentures
have been deferred and are being amortized over the life of the debt.

         The Debenture Indenture limits the amount of dividends the Company may
declare and limits the funds the Company and its subsidiaries may use to
purchase, redeem or retire the Company's capital stock.  The Indenture also
provides that the Company must maintain a minimum tangible net worth or offer
to purchase 10% of the principal amount of the Debentures issued at their
principal amount plus accrued interest.

         The fair value of the Debentures based on quoted market price at
December 31, 1995 and 1994 was $17,547,000 and $17,878,000, respectively.

         The bank term loan requires the Company to maintain covenants
including liquidity, debt to equity, interest coverage and minimum net worth.
The fair value of the bank term loan, based on rates currently available with
similar terms and maturities, at December 31, 1995 and 1994 was $4,277,000 and
$5,763,000, respectively.

         Maturities of long-term debt are as follows:

NOTE 8 - COMMON STOCK

         The Company's common stock and Series A common stock are equivalent
except that each share of common stock has one vote per share and each share of
Series A common stock has one-tenth of one vote per share.  Subject to certain
restrictions, shares of common stock are convertible on a one-for-one basis
into Series A common stock.

         The Company has a Stock-Based Incentive Compensation Plan (Option
Plan) that provides for the grant to employees of nonqualified stock options
and options designed to qualify as "incentive stock options" under the Internal
Revenue Code.  An option gives the participant the right to purchase from the
Company a specified number of shares of Series A common stock for a specified
price during a specified period not exceeding 10 years.  A total of 1,075,000
shares of Series A common stock have been reserved for issuance under the
Option Plan pursuant to the exercise of options.  All options must have an
exercise price of not less than fair market value of the underlying shares on
the date of grant.  Payment by option holders upon exercise of an option may be
made in cash, or by delivering previously owned shares of common stock, Series
A common stock or any combination thereof.

         Option activity under the Option Plan is summarized as follows:

NOTE 9 - EMPLOYEE BENEFIT PLANS

         The Company has a defined benefit pension plan (Retirement Plan)
covering substantially all of its employees.  The benefits are based on a
career average formula, which provides credit for each year based on that
year's compensation and hours of service.  The Company's funding policy is to
contribute annually not less than the minimum required by applicable law and
regulation nor more than the maximum amount that can be deducted for federal
income tax purposes.  Retirement Plan assets consist of investments in both
fixed income and equity instruments.

         The following table sets forth the Retirement Plan's funded status and

         The projected benefit obligation was determined using an assumed rate
of compensation increase of 5% at December 31, 1995 and December 31, 1994 and
weighted average discount rates of 7.25% at December 31, 1995 and 8.50% at
December 31, 1994.  The change in the weighted average discount rate had the
effect of increasing the projected benefit obligation by $6,712,000 at December
31, 1995.  The expected long-term rate of return on assets was 9.25% at
December 31, 1995 and December 31, 1994.

         The Company has an Employees' Savings Plan which provides that the
Company will supplement an employee's contribution (which may not exceed 12% of
compensation). The Company has agreed to contribute to the Plan an amount equal
to 50% of the first 6% of an employee's contributions. Company contributions
resulted in charges to earnings of $2,453,000, $2,581,000 and $2,527,000 for
the years ended December 31, 1995, 1994 and 1993, respectively.

         The Company has three nonqualified supplementary retirement plans. The
Pension Restoration Plan provides additional retirement benefits to those
executives whose compensation exceeds that includable under the Retirement
Plan. The Company's Executive Supplemental Benefit Plan provides certain
executive officers supplemental retirement benefits upon their retirement from
the Company or preretirement death benefits.  The amount of these benefits is

determined by the Company.  The Company's Supplemental Split Dollar Life
Insurance Plan provides certain other officers and key employees with a lump
sum retirement benefit, upon retirement from the Company, of $5,000 plus an
additional $5,000 for each year of participation in excess of 10 years, or a
preretirement death benefit of $200,000.  The Company has purchased life
insurance contracts on the lives of the participants. The Company owns the
contracts and is the beneficiary of contracts on the lives of the Executive
Supplemental Benefit Plan participants.  The amount of coverage is designed to
provide sufficient proceeds to recover the costs of the plan.  The cash value
of the life insurance contracts, included in other assets in the accompanying
consolidated balance sheets, was $4,345,000 and $3,589,000 at December 31, 1995
and 1994, respectively.  Premiums for the years ended December 31, 1995, 1994
and 1993 for these plans were $682,000, $674,000 and $684,000, respectively.

         The following table sets forth the supplemental plans' funded status
and amounts recognized in the Company's financial statements at December 31:

         The projected benefit obligation was determined using weighted average
discount rates of 7.25% at December 31, 1995 and 8.50% at December 31, 1994.
The change in the weighted average discount rate had the effect of increasing
the projected benefit obligation by $300,000 at December 31, 1995.

         The Company maintains medical and dental plans for its eligible
employees on a primarily self-funded basis.  Claims in excess of specified
individual and aggregate amounts are covered by insurance.  Costs and premiums
in the financial statements for the years ended December 31, 1995, 1994 and
1993 for these plans were $3,978,000, $3,998,000 and $4,579,000, respectively.

         The Company provides health care benefits to retirees based on the
cost of such benefits in the year of retirement.  The benefits are funded on a
cash basis.  Effective January 1, 1993, the Company implemented Statement of
Financial Accounting Standards No. 106, "Employers' Accounting for
Postretirement Benefits Other than Pensions" to account for these medical
benefits.

</TABLE>

         The accumulated postretirement benefit obligation was determined using
weighted average discount rates of 7.25% at December 31, 1995 and 8.50% at
December 31, 1994.  A cost increase of 12% for covered health care benefits was
assumed for 1995.  The rate was assumed to decrease ratably to 5.5% after 8
years and remain at that level thereafter.  The effect of a one percentage
point increase in the assumed health care cost trend rate for each future year
would increase the aggregate of service cost and interest cost by approximately
1% and the accumulated postretirement benefit obligation by approximately 5%.

NOTE 10 - CONTINGENCIES

         As collateral for performance on contracts, the Company is
contingently liable at December 31, 1995 in the amount of $4,902,000, under
standby letters of credit.

         A substantial portion of the Company's gross revenues is derived from
work involving hazardous materials, toxic wastes and other pollutants. Such
efforts frequently entail significant risks of liability for environmental
damage, personal injury, and fines and costs imposed by regulatory agencies.  A
substantial number of the Company's contracts require indemnification of a
client for performance claims, damages or losses unless such injury or damage
is solely the result of the client's negligence or willful acts.  The Company
has been able to insure against most liabilities it may incur in this regard.

         The Company has obtained coverage with commercial carriers to insure
against pollution liability claims.  Although this insurance covers many of the
Company's environmental exposures, there are instances where project-specific
pollution insurance policies are necessary.  The Company will continue to
evaluate exposures associated with each project to determine if additional
coverage is necessary.  The Company continues to be partially self-insured
through its subsidiary, Cardinal Indemnity Company of North America, a captive
insurance company.  Cardinal provides professional liability and pollution
coverage for deductible amounts of the commercial insurance coverage.

                              FINANCIAL STATEMENTS

         While the insurance carried by the Company may not be sufficient to
cover all claims that may arise, and while insurance carriers may not continue
to make coverage available to the Company, management believes it has provided
an adequate level of insurance coverage.

         During 1993, a trial court issued summary judgment against the Company
and awarded damages of $3,200,000 in connection with litigation of a contract
dispute. In response to this adverse decision, the Company recorded a charge of
$2,000,000 in the year ended December 31, 1993 to increase its provision for
the ultimate outcome, pending resolution of its appeal. In 1994 the Appeals
Court denied the Company's appeal of the trial court decision. Subsequent
payment of the damage award had no impact on the Company's results of
operations.

         Performance of a 1993 remediation contract was subject to several
delays and in 1994 was partially terminated for convenience by the client. The
Company submitted a claim for its costs incurred as  a result of the delays and
termination. The Company recorded net revenues aggregating approximately
$1,520,000 in the year ended December 31, 1994 as an estimate of the amount to
be received in settlement of its claim and an additional $1,800,000 in  the
year ended December 31, 1995 when negotiation of the claim was completed.

         The Company is subject to certain claims and lawsuits in connection
with work performed in the ordinary course of its business.  In the opinion of
management, such claims and lawsuits will not have a material effect on the
financial position or results of operations of the Company.

relating to state income tax benefits since it is more likely than not that
these assets will not be realized.
