                                PROXY STATEMENT

     The enclosed proxy is solicited by the board of directors of Thermo
TerraTech Inc. (the "Corporation") for use at the 1998 Annual Meeting of the
Stockholders (the "Meeting") to be held on Tuesday, September 15, 1998, at 3:00
p.m. at the offices of Thermo Electron Corporation, 81 Wyman Street, Waltham,
Massachusetts, and any adjournment thereof. The mailing address of the executive
office of the Corporation is 81 Wyman Street, Waltham, Massachusetts 02454-9046.
This proxy statement and the enclosed proxy were first furnished to Stockholders
of the Corporation on or about July 27, 1998.


                               VOTING PROCEDURES

     The board of directors intends to present to the Meeting the election of
six directors, constituting the entire board of directors.

     The representation in person or by proxy of a majority of the outstanding
shares of common stock of the Corporation, $.10 par value (the "Common Stock"),
entitled to vote at the Meeting is necessary to provide a quorum for the
transaction of business at the Meeting. Shares can only be voted if the
Stockholder is present in person or is represented by returning a properly
signed proxy. Each Stockholder's vote is very important. Whether or not you plan
to attend the Meeting in person, please sign and promptly return the enclosed
proxy card, which requires no postage if mailed in the United States. All signed
and returned proxies will be counted towards establishing a quorum for the
Meeting, regardless of how the shares are voted.

     Shares represented by proxy will be voted in accordance with your
instructions. You may specify your choice by marking the appropriate box on the
proxy card. If your proxy card is signed and returned without specifying
choices, your shares will be voted FOR the management nominees for directors and
as the individuals named as proxy holders on the proxy deem advisable on all
other matters as may properly come before the Meeting.

     In order to be elected a director, a nominee must receive the affirmative
vote of a plurality of the shares of Common Stock present and entitled to vote
on the election.  Withholding authority to vote for a nominee for director will
be treated as shares present and entitled to vote and, for purposes of
determining the outcome of the vote, will have the same effect as a vote against
the nominee. With respect to the election of directors, broker "non-votes" will
not be treated as shares present and entitled to vote on a voting matter and
will have no effect on the outcome of the vote.  A broker "non-vote" occurs when
a nominee holding shares for a beneficial holder does not have discretionary
voting power and does not receive voting instructions from the beneficial owner.

     A Stockholder who returns a proxy may revoke it at any time before the
Stockholder's shares are voted at the Meeting by written notice to the Secretary
of the Corporation received prior to the Meeting, by executing and returning a
later-dated proxy or by voting by ballot at the Meeting.

     The outstanding stock of the Corporation entitled to vote (excluding shares
held in treasury by the Corporation) as of July 23, 1998, consisted of
19,513,824 shares of Common Stock. Only Stockholders of record at the close of
business on July 23, 1998, are entitled to vote at the Meeting. Each share is
entitled to one vote.

removal.

Committees of the Board of Directors and Meetings

     The board of directors has established an audit committee and a human
resources committee, each consisting solely of outside directors. The present
members of the audit committee are Mr. Vintiadis (Chairman) and Mr. Noble.  The
audit committee reviews the scope of the audit with the Corporation's
independent public accountants and meets with them for the purpose of reviewing
the results of the audit subsequent to its completion. The present members of
the human resources committee are Mr. Noble (Chairman) and Mr. Vintiadis. The
human resources committee reviews the performance of senior members of
management, recommends executive compensation and administers the Corporation's
stock option and other stock-based compensation plans. The Corporation does not
have a nominating committee of the board of directors. The board of directors
met six times, the audit committee met twice and the human resources committee
met five times during fiscal 1998. Each director attended at least 75% of all
meetings of the board of directors and committees on which he served held during
fiscal 1998.



Compensation of Directors


     Cash Compensation

     Directors who are not employees of the Corporation, of Thermo Electron or
of any other company affiliated with Thermo Electron (also referred to as
"outside directors"), receive an annual retainer of $4,000 and a fee of $1,000
per day for attending regular meetings of the board of directors and $500 per
day for participating in meetings of the board of directors held by means of
conference telephone and for participating in certain meetings of committees of
the board of directors.  Beginning in January 1997, the non-employee chairman of
the board receives an additional meeting fee for his service equal to $1,000 per
day for attending regular meetings of the Board of Directors and $500 per day
for participating in meetings of the board of directors held by means of
conference telephone.  Payment of outside directors' fees is made quarterly.
Dr. Appleton, Mr. Hatsopoulos, Mr. Holt and Mr. Rainville are all employees of
Thermo Electron or its subsidiaries and do not receive any cash compensation
from the Corporation for their services as directors.  Directors are also
reimbursed for out-of-pocket expenses incurred in attending such meetings.

                                       3
<PAGE>
 
     Deferred Compensation Plan for Directors

     Under the Corporation's deferred compensation plan for directors (the
"Deferred Compensation Plan"), a director has the right to defer receipt of his
cash fees until he ceases to serve as a director, dies or retires from his
principal occupation. In the event of a change in control or proposed change in
control of the Corporation that is not approved by the board of directors,
deferred amounts become payable immediately. Either of the following is deemed
to be a change of control:  (a) the acquisition, without the prior approval of
the board of directors, directly or indirectly, by any person of 50% or more of
the outstanding Common Stock or 25% or more of the outstanding common stock of
Thermo Electron; or (b) the failure of the persons serving on the board of
directors immediately prior to any contested election of directors or any
exchange offer or tender offer for the Common Stock or the common stock of
Thermo Electron to constitute a majority of the board of directors at any time
within two years following any such event.  Amounts deferred pursuant to the
Deferred Compensation Plan are valued at the end of each quarter as units of the
Corporation's Common Stock. When payable, amounts deferred may be disbursed
solely in shares of Common Stock accumulated under the Deferred Compensation
Plan. A total of 41,416 shares of Common Stock have been reserved for issuance
under the Deferred Compensation Plan.  As of April 4, 1998, deferred units equal
to 25,933 full shares of Common Stock were accumulated for current directors
under the Deferred Compensation Plan.


     Directors Stock Option Plan

     The Corporation's Directors Stock Option Plan (the "Directors Plan")
provides for the grant of stock options to purchase shares of Common Stock of
the Corporation and its majority-owned subsidiaries to outside directors as
additional compensation for their service as directors.  Under the Directors
Plan, outside directors are automatically granted options to purchase 1,000
shares of Common Stock annually and are also automatically granted every five
years options to purchase 1,500 shares of the common stock of a majority-owned
subsidiary of the Corporation that is "spun out" to outside investors.

     Pursuant to the Directors Plan, outside directors receive an annual grant
of options to purchase 1,000 shares of Common Stock pursuant to the Directors
Plan at the close of business on the date of each Annual Meeting of the
Stockholders of the Corporation.  Options evidencing annual grants may be
exercised at any time from and after the six-month anniversary of the grant date
of the option and prior to the expiration of the option.  Options granted under
this provision before 1995 expire after seven years; commencing in 1995, the
option term was shortened to three years.  Shares acquired upon exercise of the
options are subject to repurchase by the Corporation at the exercise price if
the recipient ceases to serve as a director of the Corporation or any other
Thermo Electron company prior to the first anniversary of the grant date.

     In addition, under the Directors Plan, outside directors are automatically
granted every five years options to purchase 1,500 shares of common stock of
each majority-owned subsidiary of the Corporation that is "spun out" to outside
investors.  The grant occurs on the close of business on the date of the first
Annual Meeting of the Stockholders next following the subsidiary's spinout,
which is the first to occur of either an initial public offering of the
subsidiary's common stock or a sale of such stock to third parties in an arms-
length transaction, and also as of the close of business on the date of every
fifth Annual Meeting of the Stockholders of the Corporation that occurs
thereafter during the duration of the Plan.  The options granted vest and become
exercisable on the fourth anniversary of the date of grant, unless prior to such
date the subsidiary's common stock is registered under Section 12 of the
Securities Exchange Act of 1934, as amended ("Section 12 Registration"). In
the event that the effective date of Section 12 Registration occurs before the
fourth anniversary of the grant date, the option will become immediately
exercisable and the shares acquired upon exercise will be subject to
restrictions on transfer and the right of the Corporation to repurchase such
shares at the exercise price in the event the director ceases to serve as a
director of the Corporation or any other Thermo Electron company.  In the event
of Section 12 Registration, the restrictions and repurchase rights shall lapse
or be deemed to lapse at the rate of 25% per year, starting with the first
anniversary of the grant date.  These options expire after five years.

     The exercise price for options granted under the Directors Plan is the
average of the closing prices of the Common Stock as reported on the American
Stock Exchange (or other principal market on which the Common Stock is then
traded) for the five trading days immediately preceding and including the date
of grant, or, if the shares

                                       4
<PAGE>
 
are not then traded, at the last price per share paid by third parties in an
arms-length transaction prior to the option grant. As of June 29, 1998, options
to purchase 24,700 shares of Common Stock had been granted under the Director's
Plan, of which 16,500 were outstanding, 2,400 had lapsed, and 5,800 had been
exercised; and options to purchase 52,700 shares of Common Stock were reserved
and available for grant under the Director's Plan as of June 29, 1998.


     Discretionary Grants of Stock Options to Directors

     In addition to stock options granted pursuant to the Directors Plan, the
Corporation may also make discretionary grants of stock options to directors.
Beginning in fiscal 1997, the non-employee chairman of the board has received
annually a discretionary grant of options to purchase an additional 1,000 shares
of Common Stock of the Corporation.  The exercise price for discretionary option
grants is calculated in the same manner as for options granted pursuant to the
Director's Plan, and the grant is awarded at the first regular meeting of the
board of directors following the Annual Meeting of the Stockholders in
conjunction with the chairman's annual appointment as chairman of the board.


Stock Ownership Policies for Directors

     During fiscal 1997, the Human Resources Committee of the board of directors
(the "Committee") established a stock holding policy for directors.  The stock
holding policy requires each director to hold a minimum of 1,000 shares of
Common Stock.  Directors were requested to achieve this ownership level by the
1998 Annual Meeting of Stockholders.  Directors who are also executive officers
of the Corporation are required to comply with a separate stock holding policy
established by the Committee in fiscal 1997, which is described in "Committee
Report on Executive Compensation - Stock Ownership Policies."

     In addition, the Committee adopted a policy requiring directors to hold
shares of the Corporation's Common Stock equal to one-half of their net option
exercises over a period of five years.  The net option exercise is determined by
calculating the number of shares acquired upon exercise of a stock option, after
deducting the number of shares that could have been traded to exercise the
option and the number of shares that could have been surrendered to satisfy tax
withholding obligations attributable to the exercise of the option.  This policy
is also applicable to executive officers and is described in "Committee Report
on Executive Compensation - Stock Ownership Policies."


                                STOCK OWNERSHIP

     The following table sets forth the beneficial ownership of Common Stock, as
well as the common stock of Thermo Electron, Thermo Remediation and Randers, as
of May 30, 1998, with respect to (i) each person who was known by the
Corporation to own beneficially more than 5% of the outstanding shares of Common
Stock, (ii) each director, (iii) each executive officer named in the summary
compensation table under the heading "Executive Compensation" and (iv) all
directors and current executive officers as a group.

     While certain directors or executive officers of the Corporation are also
directors and executive officers of Thermo Remediation, Randers, or Thermo
Electron, all such persons disclaim beneficial ownership of the shares of Common
Stock owned by Thermo Electron and the shares of the common stock of Thermo
Remediation and Randers owned by the Corporation.

     The following table summarizes compensation for services to the Corporation
in all capacities awarded to, earned by or paid to the Corporation's chief
executive officer and its two other most highly compensated executive officers
for the last three fiscal years.  No other executive officers of the Corporation

     The Corporation is required to appoint certain executive officers and full-
time employees of Thermo Electron as executive officers of the Corporation, in
accordance with the Thermo Electron Corporate Charter. The compensation for
these executive officers is determined and paid entirely by Thermo Electron. The
time and effort devoted by these individuals to the Corporation's affairs is
provided to the Corporation under the Corporate Services Agreement between the
Corporation and Thermo Electron. Accordingly, the compensation for these
individuals is not reported in the following table.

(4)  Dr. Appleton was appointed president and chief executive officer of the
     Corporation effective September 1, 1993.  Dr. Appleton is also a vice
     president of Thermo Electron and, until 1997, served as the chief executive
     officer of Thermo Remediation.  A portion of Dr. Appleton's annual cash
     compensation (salary and bonus) has been allocated to and paid by each of
     the Corporation, Thermo Remediation and Thermo Electron over each of the
     past three fiscal years as compensation for the services provided to these
     companies based on the time he devoted to his responsibilities to these
     companies.  The annual cash compensation reported in the table for Dr.
     Appleton represents the amount paid from all sources, including the
     Corporation, solely for Dr. Appleton's services as the president and chief
     executive officer of the Corporation.  For fiscal 1998, 1997 and 1996,
     approximately 70%, 70% and 70%, respectively, of Dr. Appleton's annual cash
     compensation was paid by all sources including the Corporation for his
     services as its president and chief executive officer.  For fiscal 1998,
     1997 and 1996, an additional 20%, 20% and 20%, respectively, of Dr.
     Appleton's annual cash compensation was allocated to Thermo Remediation for
     Dr. Appleton's service as its chief executive officer, and such amount is
     not included in the table.  Bonuses paid to Dr. Appleton in 1996 and 1997
     reflect compensation decisions based on calendar year performance, in
     accordance with Thermo Electron's compensation practices for its officers.
     Bonuses granted to Dr. Appleton for periods after 1998 will reflect
     compensation decisions based on fiscal year performance.  Dr. Appleton has
     served as an officer of Thermo Electron since 1975 and has been granted
     options to purchase shares of the common stock of Thermo Electron and
     certain of its subsidiaries other than the Corporation from time to time by
     Thermo Electron or such other subsidiaries.  These options are not reported
     here as they were granted as compensation for service to Thermo Electron
     companies in capacities other than in his capacity as the president and
     chief executive officer of the Corporation.
 
(5)  Mr. Herkert was appointed an executive officer of the Corporation on May 8,
     1996.

(1)  In addition to the grant of options to purchase Common Stock of the 
     Corporation (designated in the table as TTT), options have been granted
     during fiscal 1998 to the named executive officers to purchase the common
     stock of Thermo Electron (designated in the table as TMO), Metrika Systems
     Corporation (designated in the table as MKA), ONIX Systems Inc. (designated
     in the table as ONX), The Randers Group Incorporated (designated in the
     table as RGI), Thermedics Detection Inc. (designated in the table as TDX),
     Thermo Information Solutions Inc. (designated in the table as TISI), Thermo
     Trilogy Corporation (designated in the table as TRIL), Thermo Vision
     Corporation (designated in the table as VIZ) and Trex Communications
     Corporation (designated in the table as TRCC).  All of the options granted
     during the fiscal year are immediately exercisable at the date of grant,
     except options to purchase the common stock of Thermo Information Solutions
     Inc., Thermo Trilogy Corporation and Trex Communications Corporation, which
     are not exercisable until the earlier of (i) 90 days after the effective
     date of the registration of that company's common stock under Section 12 of
     the Securities and Exchange Act of 1934 and (ii) six years from the date of
     grant.  In all cases, the shares acquired upon exercise are subject to
     repurchase by the granting corporation at the exercise price if the
     optionee ceases to be employed by such corporation or any other Thermo
     Electron company. The granting corporation may exercise its repurchase
     rights within six months after the termination of the optionee's
     employment.  For publicly traded companies, the repurchase rights generally
     lapse ratably over a five- to ten-year period, depending on the option
     term, which may vary from seven to twelve years, provided that the optionee
     continues to be employed by the Corporation or another Thermo Electron
     company.  For companies whose shares are not publicly traded, the
     repurchase rights lapse in their entirety on the sixth anniversary of the
     date of grant.  Certain options have three-year terms and the repurchase
     rights lapse in their entirety on the second anniversary of the grant date.
     The granting corporation may permit the holders of options to exercise
     options and to satisfy tax withholding obligations by surrendering shares
     equal in fair market value to the exercise price or withholding obligation.
 
(2)  The amounts shown on this table represent hypothetical gains that could be
     achieved for the respective options if exercised at the end of the option
     term.  These gains are based on assumed rates of stock appreciation of 5%
     and 10% compounded annually from the date the respective options were
     granted to their expiration date.  The gains shown are net of the option
     exercise price, but do not include deductions for taxes or other expenses
     associated with the exercise.  Actual gains, if any, on stock option
     exercises will depend on the future performance of the common stock of the
     applicable corporation, the optionee's continued employment through the
     option period and the date on which the options are exercised.
 
(3)  These options were granted under stock option plans maintained by Thermo
     Electron or its subsidiaries other than the Corporation as part of Thermo
     Electron's compensation program and accordingly are reported as a
     percentage of total options granted to employees of Thermo Electron and its
     subsidiaries.

(1)  Amounts shown in this column do not necessarily represent actual value
     realized from the sale of the shares acquired upon exercise of the option
     because in many cases the shares are not sold on exercise but continue to
     be held by the executive officer exercising the option.  The amounts shown
     represent the difference between the option exercise price and the market
     price on the date of exercise, which is the amount that would have been
     realized if the shares had been sold immediately upon exercise.


(2)  All of the options reported outstanding at the end of the fiscal year are
     immediately exercisable as of fiscal year-end, except options to purchase
     the common stock of ThermoLyte Corporation, which are not exercisable until
     the earlier of (i) 90 days after the effective date of  the registration of
     that company's common stock under Section 12 of the Securities Exchange Act
     of 1934 and (ii) nine years from the grant date, and options to purchase
     the common stock of Thermo Information Solutions Inc., Thermo Trilogy
     Corporation and Trex Communications Corporation, which are not exercisable
     until the earlier of (i) 90 days after the effective date of the
     registration of that company's common stock under Section 12 of the
     Securities Exchange Act of 1934 and (ii) six years from the grant date.  In
     all cases, the shares acquired upon exercise are subject to repurchase by
     the granting corporation at the exercise price if the optionee ceases to be
     employed by such corporation or any other Thermo Electron company. The
     granting corporation may exercise its repurchase rights within six months
     after the termination of the optionee's employment.  For publicly traded
     companies, the repurchase rights generally lapse ratably over a five- to
     ten-year period, depending on the option term, which may vary from seven to
     twelve years, provided that the optionee continues to be employed by the
     Corporation or another Thermo Electron company.  Certain options have
     three-year terms and the repurchase rights lapse in their entirety on the
     second anniversary of the grant date.  For companies whose shares are not
     publicly traded, the repurchase rights lapse in their entirety on the ninth
     anniversary (in the case of ThermoLyte Corporation) or sixth anniversary
     (in the case of Thermo Information Solutions Inc., Thermo Trilogy
     Corporation, and Trex Communications Corporation) of the grant date.

(3)  Dr. Appleton has served as a vice president of Thermo Electron since 1975
     and has been granted options to purchase shares of the common stock of
     Thermo Electron and certain of its subsidiaries other than the Corporation
     from time to time by Thermo Electron or such other subsidiaries. These
     options are not reported here as they were granted as compensation for
     service to other Thermo Electron companies in capacities other than in his
     capacity as the chief executive officer of the Corporation.


(4)  In addition to the terms described in footnote (2) above, 60,000 of the
     shares subject to option are, if acquired through exercise, restricted from
     resale until Dr. Appleton's retirement.


(5)  Options to purchase 22,500 shares of the common stock of Thermo Electron
     granted to Mr. Powell are subject to the same terms as described in
     footnote (1), except that the repurchase rights of the granting corporation
     generally do not lapse until the tenth anniversary of the grant date.  In
     the event of the employee's death or involuntary termination prior to the
     tenth anniversary of the grant date, the repurchase rights of the granting
     corporation shall be deemed to lapse ratably over a five-year period
     commencing with the fifth anniversary of the grant date.


(6)  No public market existed for the shares underlying these options as of
     April 4, 1998. Accordingly, no value in excess of exercise price has been
     attributed to these options.


(7)  Options to purchase 22,500 shares of the common stock of Thermo Electron
     granted to Mr. Herkert are subject to the same terms as described in
     footnote (1), except that the repurchase rights of the granting corporation
     generally do not lapse until the tenth anniversary of the grant date. In
     fiscal 1997 and 1998, the human resources committee of the board of
     directors of Thermo Electron accelerated the vesting of 1,800 shares and
     1,350 shares, respectively.

Severance Agreements

     Thermo Electron has entered into severance agreements with several key
employees, including Dr. Appleton.  These agreements provide severance benefits
if there is a change in control of Thermo Electron that is not approved by the
board of directors of Thermo Electron and the employee's employment with Thermo
Electron or one of its majority-owned subsidiaries is terminated, for whatever
reason, within one year thereafter.  For purposes of the severance agreements, a
change of control exists upon (i) the acquisition of 50% or more of the
outstanding common stock of Thermo Electron by any person without the prior
approval of the board of directors of Thermo Electron, (ii) the failure of the
board of directors of Thermo Electron, within two years after any contested
election of directors or tender or exchange offer not approved by the board of
directors, to be constituted of a majority of directors holding office prior to
such event or (iii) any other event that the board of directors of Thermo
Electron determines constitutes an effective change in control of Thermo
Electron.  The benefit under these agreements is stated as an initial percentage
which was established by the board of directors of Thermo Electron in 1983 and
is generally based upon the employee's age and length of service with Thermo
Electron at the time of severance.  Benefits are to be paid over a five-year
period.  The benefit to be paid in the first year is determined by applying this
percentage to the employee's highest annual total remuneration in any 12-month
period during the preceding three years.  This benefit is reduced by 10% in each
of the succeeding four years in which benefits are paid.  The initial percentage
to be so applied to Dr. Appleton is 40.1%.  Assuming severance benefits would
have been payable under such agreements as of April 4, 1998, Dr. Appleton would
have received approximately $119,906 in the first year thereof from Thermo
Electron.


                   COMMITTEE REPORT ON EXECUTIVE COMPENSATION


Executive Compensation

     All decisions on compensation for the Corporation's executive officers are
made by the human resources committee of the board of directors (the
"Committee").  In reviewing and establishing total cash compensation and stock-
based compensation for executives, the Committee follows guidelines established
by the human resources committee of the board of directors of its parent
company, Thermo Electron. The executive compensation program presently consists
of annual base salary ("salary"), short-term incentives in the form of annual
cash bonuses, and long-term incentives in the form of stock options.

     The Committee believes that the compensation of executive officers should
reflect the scope of their responsibilities, the success of the Corporation, and
the contributions of each executive to that success.  In addition, the Committee
believes that base salaries should approximate the mid-point of competitive
salaries derived from market surveys and that short-term and long-term incentive
compensation should reflect the performance of the Corporation and the
contributions of each executive.

     External competitiveness is an important element of the Committee's
compensation policy.  The competitiveness of the Corporation's total
compensation for its executives is assessed by comparing it to market data
provided by compensation consultants and by participating in annual executive
compensation surveys, primarily "Project 777," an executive compensation survey
prepared by Management Compensation Services, a division of Hewitt Associates.
The majority of firms represented in the Project 777 survey are included in the
Standard & Poor's 500 Index, but do not necessarily correspond to the companies
included in the Corporation's peer group.

     Principles of internal equity are also central to the Committee's
compensation policies.  Total compensation considered for the Corporation's
officers, whether cash or stock-based incentives, is also evaluated by comparing
it to compensation of other executives within the Thermo Electron organization
with comparable levels of responsibility for comparably sized business units.

     The process for determining each of these elements for the Corporation's
executive officers is outlined below.  For its review of the compensation of
other officers of the Corporation, the Committee follows a substantially similar
process.

                                       12
<PAGE>
 
     Base Salary

     Base salaries are set to approximate the mid-point of competitive salaries
for similar organizations of comparable size and complexity to the Corporation.
Executive salaries are adjusted gradually over time and only as necessary to
meet this objective.  Increases in base salary may be moderated by other
considerations, such as geographic or regional market data, industry trends or
internal fairness within the Corporation and Thermo Electron.  It is the
Committee's intention that over time the base salaries for the chief executive
officer and the other named executive officers will approach the mid-point of
competitive data.  The salary increases in fiscal 1998 for the chief executive
officer and the other named executive officers generally reflect this practice
of gradual increases and moderation.


     Cash Bonus

     The Committee establishes a median potential bonus for each executive by
using the market data on total cash compensation from the same executive
compensation surveys as used to determine salaries.  Specifically, the median
potential bonus plus the salary of an executive officer is approximately equal
to the mid-point of competitive total cash compensation for a similar position
and level of responsibility in businesses having comparable sales and complexity
to the Corporation. The actual bonus awarded to an executive officer may range
from zero to three times the median potential bonus. The value within the range
(the bonus multiplier) is determined at the end of each year by the Committee in
its discretion. The Committee exercises its discretion by evaluating each
executive's performance using a methodology developed by its parent corporation,
Thermo Electron, and applied throughout the Thermo Electron organization.  The
methodology incorporates measures of operating returns which are designed to
measure profitability and contributions to shareholder value, and earnings
growth, and are measures of corporate and divisional performance that are
evaluated using graphs developed by Thermo Electron intended to reward
performance that is perceived as above average and to penalize performance that
is perceived as below average.  The measures of operating returns used in the
Committee's determinations in fiscal 1998 measured return on net assets, growth
in income, and return on sales, and the Committee's determinations also included
a subjective evaluation of the contributions of each executive that are not
captured by operating measures but are considered important to the creation of
long-term value for the Stockholders.  These measures of achievements are not
financial targets that are met, not met or exceeded.  The relative weighting of
the operating measures and subjective evaluation varies among the executives,
depending on their roles and responsibilities with the organization.

     The bonuses for named executive officers approved by the Committee with
respect to fiscal 1998 performance in each instance were below the median
potential bonus, except in the case of one executive officer, due to the
measures of operating returns used by the Committee in its determinations, as
described above.  However, each of the named executive officers elected to
forego his bonus for fiscal 1998 in light of the operating and stock price
performance of the Corporation and its subsidiaries.



     Stock Option Program

     The primary goal of the Corporation and its parent company is to excel in
the creation of long-term value for the Stockholders. The principal incentive
tool used to achieve this goal is the periodic award to key employees of options
to purchase common stock of the Corporation and other Thermo Electron companies.

     The Committee and management believe that awards of stock options to
purchase the shares of both the Corporation and other companies within the
Thermo Electron group of companies accomplish many objectives. The grant of
options to key employees encourages equity ownership in the Corporation, and
closely aligns management's interests to the interests of all the Stockholders.
The emphasis on stock options also results in management's compensation being
closely linked to stock performance. In addition, because they are subject to
vesting periods of varying durations and to forfeiture if the employee leaves
the Corporation prematurely, stock options are an incentive for key employees to
remain with the Corporation long-term. The Committee believes stock option
awards in its Thermo Remediation and Randers subsidiaries, its parent
corporation, Thermo Electron, and the other majority-owned subsidiaries of
Thermo Electron are important tools in providing incentives for performance
within the entire organization.

                                       13
<PAGE>
 
     In determining awards, the Committee considers for each officer the annual
value of all options to purchase shares of the Corporation and other companies
within the Thermo Electron organization that vest in the next year and compares
the individual's total compensation using this value to competitive data. The
Committee uses a modified Black-Scholes option pricing model to determine the
value of an option award.  In addition, the Committee considers the aggregate
amount of net awards to purchase shares of Common Stock granted to all employees
over the last five years to monitor the aggregate number of awards to all
employees.  In reviewing the aggregate number of awards, the Committee considers
such factors as the size of the company, its stage of development and its growth
strategy, as well as the aggregate awards and option practices of comparably
situated companies.

     The Committee periodically awards stock options based on its assessment of
the total compensation of each executive, the actual and anticipated
contributions of each executive (which includes a subjective assessment by the
Committee of the value of the executive's future potential within the
organization), as well as the value of previously awarded options as described
above.  The option awards made to named executive officers in fiscal 1998 with
respect to the common stock of certain of the Corporation's majority-owned
subsidiaries were determined by the human resources committee of the board of
directors of the granting company using a similar analysis.  The option awards
made to the named executive officers in fiscal 1998 with respect to the common
stock of Thermo Electron were made by the Thermo Electron human resources
committee under a program that awards options to certain eligible employees
annually based on the number of shares of common stock of Thermo Electron held
by the employee as an incentive to buy and hold Thermo Electron shares.  In
addition, the named executive officers received awards to purchase shares of the
common stock of certain majority-owned subsidiaries of Thermo Electron (other
than the Corporation and its subsidiaries) due to their positions as chief
executive officer of a majority-owned subsidiary of Thermo Electron.


Stock Ownership Policies

     The Corporation's compensation program is also designed to encourage
executives to own shares of the Corporation's Common Stock. The Committee
believes that encouraging executives to retain stock acquired through its stock
option program provides an additional incentive for executive officers to follow
strategies designed to maximize long-term value to Stockholders.

     The Committee established a stock holding policy for executive officers of
the Corporation in fiscal 1997 that required executive officers to own a
multiple of their compensation in shares of the Corporation's Common Stock.  For
the chief executive officer, the multiple was one times his base salary and
reference bonus for the calendar year.  For all other officers, the multiple was
one times the officer's base salary.  The Committee deemed it appropriate to
permit officers to achieve these ownership levels over a three-year period.  The
policy was amended in 1998 to apply only to the chief executive officer.

     In order to assist officers in complying with the policy, the Committee
also adopted in fiscal 1997 a stock holding assistance plan under which the
Corporation was authorized to make interest-free loans to officers to enable
them to purchase shares of the Common Stock in the open market.  The loans are
required to be repaid upon the earlier of demand or the fifth anniversary of the
grant date, unless otherwise authorized by the Committee.  During fiscal 1998
and 1999, Dr. Appleton, the Corporation's president and chief executive officer,
received loans in the principal amount of $137,607 under this plan, the entire
amount of which was outstanding as of June 29, 1998.  This plan was also amended
in 1998 to apply only to the chief executive officer.  See "Relationship with
Affiliates - Stock Holding Assistance Plan."

     The Committee also has adopted a policy requiring its executive officers to
hold shares of the Corporation's Common Stock acquired upon the exercise of
stock options granted by the Corporation.  Under this policy, executive officers
are required to hold one-half of their net option exercises over a period of
five years.  The net option exercise is determined by calculating the number of
shares acquired upon exercise of a stock option, after deducting the number of
shares that could have been traded to exercise the option and the number of
shares that could have been surrendered to satisfy tax withholding obligations
attributable to the exercise of the options.

                                       14
<PAGE>
 
Policy on Deductibility of Compensation

     The Committee has also considered the application of Section 162(m) of the
Internal Revenue Code to the Corporation's compensation practices.  Section
162(m) limits the tax deduction available to public companies for annual
compensation paid to senior executives in excess of $1 million, unless the
compensation qualifies as "performance based" or is otherwise exempt from
Section 162(m).  The annual cash compensation paid to individual executives does
not approach the $1 million threshold, and it is believed that the stock
incentive plans of the Corporation qualify as "performance based."  Therefore,
the Committee does not believe any further action is necessary in order to
comply with Section 162(m).  From time to time, the Committee will reexamine the
Corporation's compensation practices and the effect of Section 162(m).


CEO Compensation

     Cash compensation for Dr. Appleton is reviewed by both the Committee and
the human resources committee of the board of directors of Thermo Electron, due
to his responsibilities as both the Corporation's chief executive officer and as
a vice president of Thermo Electron, the Corporation's parent company.  Each
committee evaluates Dr. Appleton's performance and proposed compensation using a
process similar to that used for the other executive officers of the
Corporation.  At the Thermo Electron level, Dr. Appleton is evaluated on his
performance related to the Corporation as well as other operating units of
Thermo Electron for which he is responsible, weighted in accordance with the
amount of time and effort devoted to each operation.  The Corporation's
Committee then reviews the analysis and determinations of the Thermo Electron
committee, makes an independent assessment of Dr. Appleton's performance as it
relates to the Corporation using criteria similar to those used for the other
executive officers of the Corporation, and then agrees to an appropriate
allocation of Dr. Appleton's compensation to be paid by the Corporation.

     In February 1998, the Committee conducted its review of Dr. Appleton's
proposed salary for fiscal 1998 and bonus for fiscal 1998 performance.  The
Committee concurred in the recommendations made by the Thermo Electron committee
and agreed to an allocation of 70% of Dr. Appleton's total cash compensation for
calendar year 1997 and fiscal 1998 to the Corporation, based on his relative
responsibilities at the Corporation and Thermo Electron.  However, Dr. Appleton
elected to forego his bonus in light of the Corporation's operating and stock
price performance in fiscal 1998.

     The Committee awarded to Dr. Appleton options to purchase 60,000 shares of
Common Stock in fiscal 1998.  This discretionary award was determined in a
manner consistent with awards to other officers, as described above under the
caption "Stock Option Program."  Dr. Appleton was also awarded options to
purchase the common stock of the Corporation's majority-owned subsidiary, The
Randers Group Incorporated ("Randers").  This option award was granted in
connection with Dr. Appleton's position as a director of Randers by its human
resources committee and was determined in a manner consistent with the
methodology followed by the Corporation's human resources committee.


                         Mr. Donald E. Noble (Chairman)
                           Mr. Polyvios C. Vintiadis

                          RELATIONSHIP WITH AFFILIATES

     Thermo Electron has adopted a strategy of selling a minority interest in
subsidiary companies to outside investors as an important tool in its future
development. As part of this strategy, the Corporation has created Thermo
Remediation as a majority-owned publicly held subsidiary.  From time to time,
Thermo Electron and its subsidiaries will create other majority-owned
subsidiaries as part of its spinout strategy.  (The Corporation and the other
majority-owned Thermo Electron subsidiaries are hereinafter referred to as the
"Thermo Subsidiaries".)

     Thermo Electron and each of the Thermo Subsidiaries recognize that the
benefits and support that derive from their mutual affiliation are essential
elements of their individual performance. Accordingly, Thermo Electron and each
of the Thermo Subsidiaries have adopted the Thermo Electron Corporate Charter
(the "Charter") to define the relationships and delineate the nature of such
cooperation among themselves. The purpose of the Charter is to ensure that (1)
all of the companies and their stockholders are treated consistently and fairly,
(2) the scope and nature of the cooperation among the companies, and each
company's responsibilities, are adequately defined, (3) each company has access
to the combined resources and financial, managerial and technological strengths
of the others, and (4) Thermo Electron and the Thermo Subsidiaries, in the
aggregate, are able to obtain the most favorable terms from outside parties.

     To achieve these ends, the Charter identifies the general principles to be
followed by the companies, addresses the role and responsibilities of the
management of each company, provides for the sharing of group resources by the
companies and provides for centralized administrative, banking and credit
services to be performed by Thermo Electron. The services provided by Thermo
Electron include collecting and managing cash generated by members, coordinating
the access of Thermo Electron and the Thermo Subsidiaries (the "Thermo Group")
to external financing sources, ensuring compliance with external financial
covenants and internal financial policies, assisting in the formulation of long-
range planning and providing other banking and credit services. Pursuant to the
Charter, Thermo Electron may also provide guarantees of debt or other
obligations of the Thermo Subsidiaries or may obtain external financing at the
parent level for the benefit of the Thermo Subsidiaries. In certain instances,
the Thermo Subsidiaries may provide credit support to, or on behalf of, the
consolidated entity or may obtain financing directly from external financing
sources. Under the Charter, Thermo Electron is responsible for determining that
the Thermo Group remains in compliance with all covenants imposed by external
financing sources, including covenants related to borrowings of Thermo Electron
or other members of the Thermo Group, and for apportioning such constraints
within the Thermo Group. In addition, Thermo Electron establishes certain
internal policies and procedures applicable to members of the Thermo Group. The
cost of the services provided by Thermo Electron to the Thermo Subsidiaries is
covered under existing corporate services agreements between Thermo Electron and
each of the Thermo Subsidiaries.

     The Charter presently provides that it shall continue in effect so long as
Thermo Electron and at least one Thermo Subsidiary participate. The Charter may
be amended at any time by agreement of the participants. Any Thermo Subsidiary,
including the Corporation, can withdraw from participation in the Charter upon
30 days' prior notice. In addition, Thermo Electron may terminate a subsidiary's
participation in the Charter in the event the subsidiary ceases to be controlled
by Thermo Electron or ceases to comply with the Charter or the policies and
procedures applicable to the Thermo Group.  A withdrawal from the Charter
automatically terminates the corporate services agreement and tax allocation
agreement (if any) in effect between the withdrawing company and Thermo
Electron. The withdrawal from participation does not terminate outstanding
commitments to third parties made by the withdrawing company, or by Thermo
Electron or other members of the Thermo Group, prior to the withdrawal. However,
a withdrawing company is required to continue to comply with all policies and
procedures applicable to the Thermo Group and to provide certain administrative
functions mandated by Thermo Electron so long as the withdrawing company is
controlled by or affiliated with Thermo Electron.

     As provided in the Charter, the Corporation and Thermo Electron have
entered into a Corporate Services Agreement (the "Services Agreement") under
which Thermo Electron's corporate staff provides certain administrative
services, including certain legal advice and services, risk management, certain
employee benefit administration, tax advice and preparation of tax returns,
centralized cash management and financial and other services to the Corporation.
The Corporation was assessed an annual fee equal to 1.0% of the Corporation's

                                       17
<PAGE>
 
revenues for these services for calendar 1996 and 1997.  The annual fee has been
reduced to 0.8% of the Corporation's total revenues for calendar 1998.  The fee
is reviewed annually and may be changed by mutual agreement of the Corporation
and Thermo Electron.  During fiscal 1998, Thermo Electron assessed the
Corporation $2,845,000 in fees under the Services Agreement.  Management
believes that the charges under the Services Agreement are reasonable and that
the terms of the Services Agreement are fair to the Corporation.  For items such
as employee benefit plans, insurance coverage and other identifiable costs,
Thermo Electron charges the Corporation based on charges attributable to the
Corporation. The Services Agreement automatically renews for successive one-year
terms, unless canceled by the Corporation upon 30 days' prior notice.  In
addition, the Services Agreement terminates automatically in the event the
Corporation ceases to be a member of the Thermo Group or ceases to be a
participant in the Charter. In the event of a termination of the Services
Agreement, the Corporation will be required to pay a termination fee equal to
the fee that was paid by the Corporation for services under the Services
Agreement for the nine-month period prior to termination. Following termination,
Thermo Electron may provide certain administrative services on an as-requested
basis by the Corporation or as required in order to meet the Corporation's
obligations under Thermo Electron's policies and procedures.  Thermo Electron
will charge the Corporation a fee equal to the market rate for comparable
services if such services are provided to the Corporation following termination.

     As of April 4, 1998, $29,583,000 of the Corporation's cash equivalents were
invested in a repurchase agreement with Thermo Electron. Under this agreement,
the Corporation in effect lends excess cash to Thermo Electron, which Thermo
Electron collateralizes with investments principally consisting of corporate
notes, U.S. government agency securities, money market funds and other
marketable securities, in the amount of at least 103% of such obligation. The
Corporation's funds subject to the repurchase agreement are readily convertible
into cash by the Corporation. The repurchase agreement earns a rate based on the
90-day Commercial Paper Composite Rate plus 25 basis points, set at the
beginning of each quarter.

     The Corporation leases an office and operating facility from Thermo
Electron.  The total rental payments made to Thermo Electron during fiscal year
1998 under these agreements was $166,000.

     The Corporation and Thermo Electron entered into a development agreement
under which Thermo Electron agreed to fund up to $4,000,000 of the direct and
indirect costs of the Corporation's development of soil-remediation centers.  In
exchange for this funding, the Corporation granted Thermo Electron a royalty
equal to approximately 3% of net revenues from soil-remediation services
performed at the centers developed under this agreement.  The royalty payments
may cease if the amounts paid by the Corporation yield a certain internal rate
of return to Thermo Electron on the funds advanced to the Corporation under this
agreement.  The Corporation paid Thermo Electron royalties of $115,000 in fiscal
1998.

     From time to time, the Corporation may transact business with the other
companies in the Thermo Group.  In fiscal 1997, the Corporation's Thermo
Remediation Inc. subsidiary paid Thermo Coleman Corporation, a majority-owned
subsidiary of Thermo Electron, $86,000, for a Global Positioning System unit and
related services.  In fiscal 1998, Thermo Remediation Inc. paid Thermo Coleman
Corporation $85,000 for upgrades to that unit and related services.

     At April 4, 1998, the Corporation owed Thermo Electron and its other
subsidiaries an aggregate of $2,341,000 for amounts due under the Corporate
Services Agreement and related administrative charges, for other products and
services, and for miscellaneous items, net of amounts owed to the Corporation by
Thermo Electron and its other subsidiaries for miscellaneous items.  The largest
amount of net indebtedness owed by the Corporation to Thermo Electron and its
other subsidiaries since March 29, 1997 was $3,283,000.  These amounts do not
bear interest and are expected to be paid in the normal course of business.

     The Corporation's Thermo EuroTech N.V. subsidiary, along with certain other
Thermo Subsidiaries, participates in a notional pool arrangement with ABN AMRO,
which includes a $50 million credit facility.  Only European-based Thermo
Subsidiaries participate in this arrangement.  Under this arrangement the Bank
notionally combines the positive and negative cash balances held by the
participants to calculate the net interest yield/expense for the group.  The
benefit derived from this arrangement is then allocated based on balances
attributable to the

                                       18
<PAGE>
 
respective participants.  Thermo Electron guarantees all of the obligations of
each participant in this arrangement.  In addition, funds on deposit under this
arrangement provide credit support for overdraft obligations of other
participants.  As of April 4, 1998, Thermo EuroTech N.V. had a negative cash
balance of approximately $6,041,000 based on an exchange rate of $0.4797/NLG1.00
as of April 4, 1998.  For 1997, the average annual interest rate earned on NLG
deposits by participants in this credit arrangement was approximately 4.8% and
the average annual interest rate paid on NLG overdrafts was approximately 4.8%.


Stock Holding Assistance Plan

     In fiscal 1997, the Corporation adopted a stock holding policy which
requires its executive officers to acquire and hold a minimum number of shares
of Common Stock.  In order to assist the executive officers in complying with
the policy, the Corporation also adopted a stock holding assistance plan under
which it may make interest-free loans to certain key employees, including its
executive officers, to enable such employees to purchase the Common Stock in the
open market.  During fiscal 1998 and 1999, Dr. Appleton received loans in the
principal amount of $137,607 under this plan to purchase 20,000 shares, the
entire amount of which was outstanding as of June 29, 1998.  The loan is
repayable upon the earlier of demand or the fifth anniversary of the date of the
loan, unless otherwise authorized by the human resources committee of the
Corporation's board of directors.  This policy and plan were amended in 1998 to
apply only to the chief executive officer of the Corporation in the future.


                 APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

     The board of directors has appointed Arthur Andersen LLP as independent
public accountants for fiscal 1999. Arthur Andersen LLP has acted as independent
public accountants for the Corporation since its inception in 1986.
Representatives of that firm are expected to be present at the Meeting, will
have the opportunity to make a statement if they desire to do so and will be
available to respond to questions. The board of directors has established an
audit committee, presently consisting of two outside directors, the purpose of
which is to review the scope and results of the audit.


                                  OTHER ACTION

     Management is not aware at this time of any other matters that will be
presented for action at the Meeting. Should any such matters be presented, the
proxies grant power to the proxy holders to vote shares represented by the
proxies in the discretion of such proxy holders.


                             STOCKHOLDER PROPOSALS

     Proposals of Stockholders intended to be included in the proxy statement
and form of proxy relating to the 1999 Annual Meeting of the Stockholders of the
Corporation and to be presented at such meeting must be received by the
Corporation for inclusion in the proxy statement and form of proxy no later than
March 30, 1999.  Notices of Stockholder proposals submitted outside the
processes of Rule 14a-8 of the Securities Exchange Act of 1934, as amended
(relating to proposals to be presented at the meeting but not included in the
Corporation's proxy statement and form of proxy), will be considered untimely --
and thus the Corporation's proxy may confer discretionary voting authority on
the persons named in the proxy with regard to such proposals -- if received
after June 12, 1999.
