Item 1. Business

(a)  General Development of Business

     The Randers Group Incorporated (Randers) provides comprehensive engineering
and outsourcing services in such areas as water and wastewater treatment,
highway and bridge projects, process engineering, construction management, and
operational services.

     In May 1997, Thermo TerraTech Inc. purchased a controlling interest in
Randers. Subsequently, Thermo TerraTech entered into a definitive agreement to
transfer The Killam Group Inc. to Randers in exchange for additional shares of
Randers' common stock. As a result of these transactions, The Killam Group is
deemed to be the "accounting acquiror," and historical results for Randers have
been restated to solely reflect the financial information of The Killam Group
for periods prior to May 12, 1997, and to reflect the combined results of The
Killam Group and Randers (collectively, the Company or the Registrant) from May
12, 1997, the date on which Thermo TerraTech became the majority owner of
Randers. See Note 2 of Notes to Consolidated Financial Statements.

     The Company's Killam Associates, Inc. subsidiary provides environmental
consulting and engineering services and specializes in wastewater treatment and
water resources management. The Company's BACKillam subsidiary provides both
private- and public-sector clients with a range of consulting services that
address transportation planning and design. The Company's Randers subsidiary
provides design engineering, project management, and construction services for
industrial clients in the manufacturing, pharmaceutical, and chemical-processing
industries. In November 1996, Thermo TerraTech acquired Carlan Consulting Group,
Inc. a provider of transportation and environmental consulting and professional
engineering and architectural services, and subsequently transferred it to the
Company.

     The Company was originally organized as a partnership in January 1974, and
was incorporated in January 1976. Following the completion of the transactions
described above, Thermo TerraTech will own 120,551,051 shares of the common
stock of the Company, representing 95% of such stock outstanding. A publicly
traded subsidiary of Thermo Electron Corporation, Thermo TerraTech provides
industrial outsourcing services and manufacturing support encompassing a broad
range of specializations, including infrastructure engineering, design and
construction, environmental compliance, laboratory-testing and metal treating.

     As of April 4, 1998, Thermo Electron owned 1,255,000 shares of the
Company's common stock, representing 1.0% of the Company's stock outstanding
following the completion of the transactions described above. Thermo Electron is
a world leader in environmental-monitoring and analysis instruments, papermaking
and recycling equipment, biomedical products such as heart-assist devices and
mammography systems, biomass electric power generation, and other specialized
products and technologies. Thermo Electron also provides a range of services
related to environmental quality and personal care.

                           Forward-looking Statements

     Forward-looking statements, within the meaning of Section 21E of the
Securities Exchange Act of 1934, are made throughout this Annual Report on Form
10-K. For this purpose, any statements contained herein that are not statements
of historical fact may be deemed to be forward-looking statements. Without
limiting the foregoing, the words "believes," "anticipates," "plans," "expects,"
"seeks," "estimates," and similar expressions are intended to identify
forward-looking statements. There are a number of important factors that could
cause the results of the Company to differ materially from those indicated by
such forward-looking statements, including those detailed under the heading
"Forward-looking Statements" in the Registrant's Fiscal 1998 Annual Report to
Shareholders, which statements are incorporated herein by reference.

(b)  Financial Information About Industry Segments

     The Company conducts business in one segment: environmental services. The
Company provides comprehensive engineering and outsourcing services in such
areas as water and wastewater treatment, highway and bridge projects, process
engineering, construction management, inspection, and operational services.

(c)  Description of Business

     (i) Principal Services and Products

     The Company provides comprehensive environmental consulting and
professional engineering services to private- and public-sector clients. These
services include the design and resident observation of water supply and
wastewater treatment facilities; investigations of different methods to clean up
hazardous-waste sites; assistance in obtaining government permits;
transportation-related and similar types of infrastructure engineering, survey,
and land-use planning; and support services including mechanical, electrical,
and structural engineering. In addition, the Company provides natural resource
management services including environmental-impact studies.

     Through its Killam Associates subsidiary, the Company specializes in the
design, planning, and construction observation of municipal and privately owned
water-treatment plants, waste treatment plants, and hazardous-wastewater
facilities. The Company provides full-service contract operations to plant
owners in the public and private sectors. These services facilitate regulatory
compliance; optimize day-to-day plant operations; reduce costs; provide
competent, experienced personnel; and promote good community relations.

     Through its BACKillam subsidiary, the Company provides a broad range of
bridge and highway engineering services. Projects include bridge inspection,
rating and rehabilitation; new bridge design; highway corridor planning studies
for new route alignment of major state highways; design of the reconstruction
and widening of existing major roads; and construction inspection on both
highway and bridge projects.

<PAGE>

     Results from May 1997, include the results of Randers, a provider of design
engineering, project management, and construction services for industrial
clients in the manufacturing, pharmaceutical, and chemical-processing
industries, principally in Michigan, Ohio, Illinois, Massachusetts, and West
Virginia.

     Through its Carlan subsidiary, the Company provides transportation and
environmental consulting and professional engineering and architectural
services.

     A substantial portion of the Company's sales are made to existing customers
on a repeat basis. The Company's services are often performed as multi-year
studies. In addition to federal, state, and local governments, customers include
public utilities, waste management companies, oil refineries, mining companies,
chemical manufacturers, architectural and engineering firms, and a variety of
service companies involved with real estate transactions.

     (ii) New Products

     The Company has made no commitments to new products that would require the
investment of a material amount of the Company's assets.

     (iii) Raw Materials

     Since the Company's business is service oriented, it does not involve the
processing of raw materials and is not dependent on fluctuations in the supply
or price of raw materials. To date, the Company has not experienced any
difficulty in obtaining any of the materials or components used in its
operations and does not foresee any such difficulty in the future. The Company
has multiple sources for all of its significant raw material needs.

     (iv) Patents, Licenses and Trademarks

     The Company does not own or license any patents, trademarks, licenses,
franchises or concessions which are material to the Company's business. The
Company believes that its business depends primarily upon the technical and
marketing expertise of its personnel.

     (v) Seasonal Influences

     A majority of the Company's businesses experience seasonal fluctuations.
Site investigation work and certain environmental testing services may decline
in winter months as a result of severe weather conditions.

     (vi) Working Capital Requirements

     In general, there are no special inventory requirements or credit terms
extended to customers that would have a material adverse effect on the Company's
working capital.


                                       4
<PAGE>

    (vii) Dependency on a Single Customer

     No single customer accounted for more than 10% of the Company's total
revenues in any of the past three years.

     (viii) Backlog

     The Company's backlog of firm orders was $53,669,000 and $49,397,000 as of
April 4, 1998, and March 29, 1997, respectively. Included in the Company's
backlog at fiscal year-end 1998 and 1997 is the incomplete portion of contracts
that are accounted for using the percentage-of-completion method. Certain of
these contracts are subject to cancellation by the customer upon payment of a
cancellation charge. Of the fiscal 1998 backlog amount, substantially all orders
are expected to be filled within fiscal 1999.

     (ix) Government Contracts

     Not applicable.

     (x) Competition

     The Company's businesses are engaged in highly competitive markets in all
of its service areas. These markets tend to be regional. In its geographic
service area, competition consists of small, one- to three-person firms offering
a limited scope of services, as well as much larger firms that may be regional,
national, or international in the scope of services they offer. The principal
competitive factors for the Company are: reputation; experience; price; breadth
and quality of services offered; and technical, managerial, and business
proficiency.

     (xi) Environmental Protection Regulations

     The Company believes that compliance by the Company with federal, state,
and local environmental protection regulations will not have a material adverse
effect on its capital expenditures, earnings, or competitive position.

     (xii) Number of Employees

     As of April 4, 1998, the Company employed 711 people. None of the Company's
employees is represented by a union. The Company believes that relations with
its employees are good.

     Foreign Operations

operations.
