     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. Collins (Chairman), Mr. Crisp and Mr.

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. Crisp (Chairman), Mr. Collins
and Dr. Zervas. The Human Resources Committee reviews the performance of senior
members of management, recommends executive compensation and administers the
Corporation's stock-based compensation plans. The Corporation does not have a
nominating committee of the Board of Directors. The Board of Directors met
eleven times, the Audit Committee met three times and the Human Resources
Committee met five times during fiscal 1996. Each Director attended at least 75%
of all meetings of the Board of Directors and Committees on which he served held
during fiscal 1996.

COMPENSATION OF DIRECTORS

     CASH COMPENSATION

     Directors who are not employees of the Corporation, of Thermo Electron or
of any other companies 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.  Payment of outside Directors' fees is made quarterly.
Dr. G. Hatsopoulos, Mr. J. Hatsopoulos and Mr. Weinstein are all employees of
Thermo Electron 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 meetings.

     DEFERRED COMPENSATION PLAN FOR DIRECTORS

     Under the 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 occurrence, without the prior approval of the Board of
Directors, of the acquisition, directly or indirectly, by any person of 50% or
more of the outstanding Common Stock or 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 22,500 shares of Common Stock have been reserved for issuance
under the Deferred Compensation Plan. As of  December 28, 1996, deferred units
equal to 4,252.72  shares of Common Stock were accumulated under the Deferred
Compensation Plan.

     DIRECTORS STOCK OPTION PLAN

     In 1991, the Corporation adopted a directors stock option plan (the
"Directors Plan"), which was amended in 1995. The Directors Plan provides for
the grant of stock options to purchase shares of Common Stock 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.   In addition, the Directors Plan
provides for the automatic grant every five years of 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.

     Prior to January 1, 1996, the Directors Plan provided for the grant of
stock options upon a Director's initial appointment.  Outside Directors
appointed before the amendment of the plan received an option to purchase 21,600
shares of Common Stock upon their initial appointment or election.  Options
granted prior to 1996 are currently exercisable, subject to restrictions upon
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 another Thermo Electron company.  Such repurchase rights lapse
ratably over a five-year period, commencing with the first anniversary of the
grant date.  These options expire on the seventh anniversary of the grant date,
unless the Director dies or otherwise ceases to serve as a Director of the
Corporation or any other Thermo Electron company prior to that date.  The grant
of options upon a Director's appointment was discontinued on December 31, 1995,
pursuant to the terms of the plan, as amended.


     Pursuant to the amended Directors Plan, outside Directors receive an annual
grant of options to purchase 1,000 shares of Common Stock  at the close of
business on the date of each Annual Meeting of Stockholders of the Corporation
to each outside Director then holding office.  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 on the third
anniversary of the grant date.  Shares acquired upon exercise of the options are
subject to

                                      A-3

<PAGE>
 
repurchase by the Corporation at the exercise price if the recipient ceases to
serve as a Director of the Corporation or another Thermo Electron company prior
to the first anniversary of the grant date.

     In addition, under the amended Directors Plan, outside Directors are
automatically granted options to purchase 1,500 shares of common stock of each
majority-owned subsidiary that is "spun out" to outside investors.  The grant
occurs on the close of business on the date of the first Annual Meeting of
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.  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
exercisable 90 days after the effective date 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 another 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 preceding and including the date of grant, or,
if the shares are not then traded, at the last price paid per share by third
parties in an arms-length transaction prior to the option grant.  An aggregate
of 225,000 shares of Common Stock has been reserved for issuance under the
Directors Plan.

STOCK OWNERSHIP POLICIES FOR DIRECTORS

     During fiscal 1996, 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 are 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 1996. The stock holding policy specifies
an appropriate level of ownership of the Corporation's Common Stock as a
multiple of the officer's compensation. For the chief executive officer, the
multiple is one times his base salary and reference bonus for the calendar year.
For all other executive officers, the multiple is 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.


     In addition, the Committee adopted a policy requiring Directors to hold a
certain number of shares of the Corporation's Common Stock acquired upon the
exercise of stock options. Under this policy, Directors are required to hold
shares of 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. Under this policy, the executive officers are
required to hold shares of 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.


                                STOCK OWNERSHIP

     The following table sets forth the beneficial ownership of Common Stock, as
well as the common stock of Thermo Electron, and ThermoLase Corporation
("ThermoLase") and Trex Medical Corporation ("Trex Medical"), each a majority-
owned subsidiary of the Corporation, as of December 28, 1996, 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 and nominee for
Director, (iii) each executive officer named in the summary compensation table
under the heading "Executive Compensation" and (iv) all Directors and executive
officers as a group.

     While certain Directors and executive officers of the Corporation are also
Directors and executive officers of Thermo Electron or its subsidiaries other
than the Corporation, all such persons disclaim beneficial ownership of the
shares of Common Stock owned by Thermo Electron.

<PAGE>
 
(1)  Annual compensation for executive officers is reviewed and determined on a
     calendar year basis, even though the Corporation's fiscal year ends in
     September. The Corporation changed its fiscal year-end to September from
     December in 1995, and as a consequence, the salary data for fiscal 1995
     reflects salary paid during the nine-month period from January 1, 1995 to
     September 30, 1995. Salary data for subsequent fiscal years represents
     salary paid during the Corporation's full fiscal year.

(2)  The bonus amount presented for fiscal 1995 represents the bonus paid for
     performance during calendar 1995.  Bonuses have not yet been determined for
     calendar 1996; therefore, the bonus amounts shown for fiscal 1996 are
     estimates.

(3)  Options to purchase Common Stock of the Corporation awarded to the named
     executive officers are followed by the designation "TKN."  Mr. Weinstein
     and Mr. Rufeh have been granted certain options to purchase common stock of
     Thermo Electron and certain of its subsidiaries other than the Corporation
     and its subsidiaries, ThermoLase (designated in the table as "TLZ") and
     Trex Medical (designated in the table as "TXM"), from time to time by
     Thermo Electron or its other subsidiaries.  These options are not reported
     here as they were granted as compensation for service to the other Thermo
     Electron companies in capacities other than in their capacities as officers
     of the Corporation.  The named executive officers of the Corporation have
     been granted options to purchase common stock of Thermo Electron and
     certain its other subsidiaries as part of Thermo Electron's stock option
     program in their capacities as officers of the Corporation.  Options have
     been granted during the period covered by the table to the named executive
     officers in the following Thermo Electron companies:  Thermo Electron
     (designated in the table as TMO), Thermo BioAnalysis Corporation
     (designated in the table as TBA), Thermo Fibergen Inc. (designated in the
     table as TFG), ThermoLyte Corporation (designated in the table as TLT),
     Thermo Optek Corporation (designated in the table as TOC), ThermoQuest
     Corporation (designated in the table as TMQ) and Thermo Sentron Inc.
     (designated in the table as TSR).   The shares of common stock of Thermo
     Electron reported in the table reflect a three-for-two stock split
     distributed in June 1996 in the form of a 50% stock dividend.

(4)  Represents the amount of matching contributions made by the individual's
     employer on behalf of executive officers participating in the Thermo
     Electron 401(k) plan or, as to Mr. Pellegrino and Mr. Kirshner for fiscal
     1993, the LORAD 401(k) plan.

(5)  Mr. Weinstein was appointed the Corporation's Chief Executive Officer
     effective as of February 26, 1996.  He was also appointed a vice president
     of Thermo Electron effective as of February 26, 1996, and a portion of his
     annual cash compensation (salary and bonus) has been allocated to and paid
     by Thermo Electron since the commencement of his employment for the time he
     devoted to his responsibilities in that capacity.  The annual cash
     compensation (salary and bonus) reported in the table for Mr. Weinstein
     represents the amount paid by the Corporation and all other sources for Mr.
     Weinstein's services as its chief executive officer.  For fiscal 1996,
     approximately 50% of Mr. Weinstein's aggregate salary and bonus earned in
     all capacities throughout the Thermo Electron organization was paid by the
     Corporation for his services as chief executive officer.

(6)  Represents the amount of compensation attributable to an interest-free loan
     provided to Mr. Weinstein pursuant to the Corporation's Stock Holding
     Assistance Plan.  See "Relationship with Affiliates - Stock Holding
     Assistance Plan."

(7)  Prior to February 1997, Mr. Rufeh served as a vice president of Thermo
     Electron, as well as the president of the Corporation.  He also served as
     the chief executive officer of the Corporation until February 1996. A
     portion of Mr. Rufeh's annual cash compensation (salary and bonus) has been
     allocated to and paid by Thermo Electron for the time he devoted to his
     responsibilities as a vice president of Thermo Electron. The annual cash
     compensation (salary and bonus) reported in the table for Mr. Rufeh
     represents the amount paid by the Corporation and all other sources for Mr.
     Rufeh's services to the Corporation and its subsidiaries.

                                      A-9

<PAGE>
 
     For 1996, 1995, 1994 and 1993, 90%, 90%, 90% and 81%, respectively, of Mr.
     Rufeh's aggregate salary and bonus earned in all capacities throughout the
     Thermo Electron organization was paid by the Corporation for his services
     in all capacities to the Corporation and its subsidiaries.

(8)  Mr. Pellegrino and Mr. Kirshner were first appointed executive officers of
     the Corporation in November 1992 in connection with the acquisition of
     LORAD Corporation by the Corporation.  The salary and bonus for each of Mr.
     Pellegrino and Mr. Kirshner are determined by employment agreements entered
     into with the Corporation at the time LORAD Corporation was acquired.  Mr.
     Pellegrino also serves as a Director of ThermoQuest Corporation, a majority
     owned subsidiary of Thermo Electron.  Options granted to Mr. Pellegrino in
     his capacity as a Director of ThermoQuest are not included in the table as
     they were granted for service in a capacity other than in his capacity as
     an officer of the Corporation.

(9)  In addition to the matching contribution referred to in footnote (4), such
     amount includes $4,614, representing the market value of 115 shares of
     Thermo Electron common stock received by Mr. Kirshner in May 1996 at Thermo
     Electron's Annual Management Conference in recognition of his managerial
     achievements.

STOCK OPTIONS GRANTED DURING FISCAL 1996

     Mr. Weinstein and Mr. Rufeh have been granted options to purchase common
stock of Thermo Electron and certain of its subsidiaries from time to time as
compensation for service to other Thermo Electron companies in capacities other
than in his capacity as chief executive officer of the Corporation.
Accordingly, options granted by Thermo Electron companies other than the
Corporation and its subsidiaries have not been reported here. It has not been
the Corporation's policy in the past to grant stock appreciation rights, and no
such rights were granted during fiscal 1996.

</TABLE>

(1)  The shares of common stock of Thermo Electron shown in the table reflect a
     three-for-two stock split distributed in June 1996 in the form of a 50%
     stock dividend.  All of the options granted during the fiscal year are
     immediately exercisable, except options to purchase ThermoLyte Corporation
     (designated in the table as TLT), 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 (the "Exchange Act") and (ii) nine years after 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 the Corporation or another 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 that are not
     publicly traded, the repurchase rights lapse in their entirety on the ninth
     anniversary of the grant date.  As to the options to purchase shares of the
     common stock of Trex Medical Corporation granted to Mr. Rufeh, Mr.
     Pellegrino, Mr. Kirshner and Dr. Tang, the repurchase rights are deemed to
     lapse 20% per year commencing on the sixth anniversary of the grant date.
     Certain options granted as part of Thermo Electron's stock option program
     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 such 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
     granting 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 and accordingly are reported as a percentage to total options
     granted to employees of Thermo Electron and its public subsidiaries.

 </TABLE>

(1)  The shares of the common stock shown in the table have been adjusted to
     reflect three-for-two stock splits, each in the form of a 50% stock
     dividend, distributed by Thermo Electron in June 1996 and Thermo Fibertek
     Inc. in June 1996.  All of the options reported outstanding at the end of
     the fiscal year are immediately exercisable as of fiscal year-end, except
     ThermoLyte Corporation (designated in the table as TLT), 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
     Exchange Act and (ii) nine years after the grant date.  In all cases, the
     shares acquired upon exercise of the options reported in the table are
     subject to repurchase by the granting corporation at the exercise price if
     the optionee ceases to be employed by such corporation or another 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 that are not publicly traded, the repurchase rights
     lapse in their entirety on the ninth anniversary of the grant date.  As to
     the options to purchase shares of the common stock of Trex Medical
     Corporation granted to Mr. Rufeh, Mr. Pellegrino, Mr. Kirshner and Dr.
     Tang, the repurchase rights are deemed to lapse 20% per year commencing on
     the sixth anniversary of the grant date.  Certain options granted as part
     of Thermo Electron's stock option program have three-year terms, and the
     repurchase rights lapse in their entirety on the second anniversary of the
     grant date.

(2)  As officers of Thermo Electron, Mr. Weinstein and Mr. Rufeh also hold
     unexercised options to purchase common stock of Thermo Electron and its
     subsidiaries other than the Corporation. These options are not reported in
     the table as they were granted as compensation for service to other Thermo
     Electron companies in capacities other than in  their  capacities as
     officers of the Corporation.

(3)  Options to purchase 22,500 shares of the common stock of Thermo Electron
     granted to each of Mr. Kirshner and Mr. Pellegrino are subject to the same
     terms 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 have
     lapsed ratably over a five-year period commencing with the fifth
     anniversary of the grant date.

(4)  No public market existed for the shares as of December 28, 1996.
     Accordingly, no value in excess of the exercise price has attributed to
     these options.

EMPLOYMENT AGREEMENTS

     In connection with the acquisition of the LORAD Corporation ("LORAD") in
November 1992, the Corporation entered into an employment agreement with each of
Mr. Anthony J. Pellegrino and Mr. Hal Kirshner.  Mr. Pellegrino's agreement
calls for Mr. Pellegrino to serve as Chairman of the Board and Chief Executive
Officer  of LORAD until December 31, 1995, at a base salary of $250,000 per year
plus bonus.  Mr. Kirshner's agreement 

                                     A-13

<PAGE>
 
calls for Mr. Kirshner to serve as President and Chief Operating Officer of
LORAD until December 31, 1995, at a base salary of $200,000 per year plus bonus.
These agreements expired on December 31, 1995.

SEVERANCE AGREEMENTS

     In 1988, Thermo Electron entered into severance agreements with several of
its key employees, including key employees of the Corporation and other
majority-owned subsidiaries. These agreements provide severance benefits if
there is a change of 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 the majority-owned subsidiary is terminated, for whatever reason,
within one year thereafter.  For purposes of the agreement, 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 of control of Thermo Electron.   Each of the
recipients of these agreements would receive a lump-sum benefit at the time of a
qualifying severance (as defined below) equal to the highest total cash
compensation paid to the employee by Thermo Electron or the majority-owned
subsidiary in any 12-month period during the three years preceding the
qualifying severance. A qualifying severance exists (i) if the employment of the
executive officer is terminated for any reason within one year after a change in
control of Thermo Electron or (ii) a group of directors of Thermo Electron
consisting of directors of Thermo Electron on the date of the severance
agreement or, if an election contest or tender or exchange offer for Thermo
Electron's common stock has occurred, the directors of Thermo Electron
immediately prior to such election contest or tender or exchange offer, and any
future directors who are nominated or elected by such directors, determines that
any other termination of the executive officer's employment should be treated as
a qualifying severance. The benefits to be provided are limited so that the
payments would not constitute so-called "excess parachute payments" under
applicable provisions of the Internal Revenue Code of 1986. Assuming that
severance benefits would have been payable under these agreements as of
September 28, 1996, Mr. Rufeh would have received approximately $335,000.

                         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, Thermo Electron and certain of its
subsidiaries have created several privately and publicly held majority-owned
subsidiaries. The Corporation has created ThermoLase Corporation ("ThermoLase")
and Trex Medical Corporation ("Trex Medical") as publicly held, majority-owned
subsidiaries. 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 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 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

                                     A-15

<PAGE>
 
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. Thermo Electron assessed the Corporation an annual fee equal to
1.2% and 1.25% of the Corporation's revenues for these services in calendar 1995
and for periods prior to calendar 1995, respectively. Effective January 1, 1996,
the fee was reduced to 1.0% of the Corporation's revenues. The fee may be
changed by mutual agreement of the Corporation and Thermo Electron. During
fiscal 1996, Thermo Electron assessed the Corporation $1,906,000 in fees under
the Services Agreement. Management believes that the charges under the Services
Agreement are reasonable and that such fees are representative of the expense
the Corporation would have incurred on a stand-alone basis. For additional items
such as employee benefit plans, insurance coverage and other identifiable costs,
Thermo Electron charges the Corporation based on costs 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.

     From time to time, the Corporation may transact business with other
companies in the Thermo Group. In fiscal 1996, such transactions included the
following. A majority-owned subsidiary of Thermo Electron provides contract
administration and data processing services to the Corporation. The Corporation
was charged $90,000 for such services for fiscal 1996.

     The Corporation leased two office and research facilities from Thermo
Electron under an agreement that was terminated in June 1996. The rental
payments made to Thermo Electron during fiscal 1996 were $89,000.  In connection
with the Corporation's decision to close its Waltham facilities and because
Thermo Electron desires to sell these facilities, the Corporation vacated these
facilities in June 1996.

     Trex Medical has an arrangement with the Tecomet division of Thermo
Electron for the manufacture of Trex Medical's proprietary HTC grid. Under this
arrangement Tecomet manufactures the grid for Trex Medical pursuant to written
purchase orders. During fiscal 1996, Trex Medical purchased 331 grids for an
aggregate purchase price of $397,000 under this arrangement. In addition, Trex
Medical paid Tecomet $250,000 during fiscal 1996 for research and development
provided by Tecomet in connection with this project. Trex Medical owns the
intellectual property rights to the grid.

     Under an arrangement with Thermedics Detection Inc., a subsidiary of
Thermedics Inc., a majority-owned subsidiary of Thermo Electron, Trex Medical
manufactures an X-ray source that is used as a component to a fill-measuring
device produced by Thermedics Detection. Trex Medical manufactures these X-ray
sources for Thermedics Detection pursuant to written purchase orders. During
fiscal 1996, Thermedics Detection purchased 100 units from Trex Medical for an
aggregate purchase price of $361,000 under this arrangement.

     In September 1995, the Corporation borrowed $8,000,000 from Thermo Electron
pursuant to a promissory note, due September 1996, and bearing interest at the
90-day Commercial Paper Composite Rate plus 25 basis points. This note was
repaid in September 1996. In September 1996, the Corporation borrowed $2,000,000
from Thermo Electron pursuant to a promissory note, due April 1997, and bearing
interest at the 90-day Commercial Paper Composite Rate plus 25 basis points.

     The Corporation sold its thermo electrics and thermionics businesses to two
subsidiaries of Thermo Electron, for approximately $860,000, which represents
the net book value of the net assets transferred.

Thermo Electron, which Thermo Electron collateralizes with investments
principally consisting of corporate notes, U.S. government agency securities,
money market funds, commercial paper 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.

     Thermo Electron owned approximately 51% of the Corporation's outstanding
Common Stock on December 28, 1996. Thermo Electron intends for the foreseeable
future to maintain at least 50% ownership of the Corporation. This may require
the purchase by Thermo Electron of additional shares of the Corporation's Common
Stock from time to time as the number of outstanding shares issued by the
Corporation increases. These and other purchases may be made either in the open
market or directly from the Corporation.

     In November 1995, Mr. Crisp and Mr. Rufeh, Directors of the Corporation,
and Mr. Kirshner, Mr. Pellegrino and Dr. Spivey, executive officers of the
Corporation, purchased from Trex Medical 10,000, 19,600, 100,000, 20,000 and
9,800 shares of Trex Medical common stock, respectively, for an aggregate
purchase price of $102,500, $200,900, $1,025,000, $205,000 and $100,450,
respectively, in a private placement of 1,852,000 shares of common stock by Trex
Medical at $10.25 per share.

STOCK HOLDING ASSISTANCE PLAN

     In 1996, 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 1996, Mr. Weinstein received a loan in the principal amount of
$375,003.85 under this plan to purchase 10,000 shares. The loan to Mr. Weinstein
is payable on demand and requires that 20% of the principal amount of the loan
be repaid from the bonus payable to Mr. Weinstein in each of the next five
years, commencing with the bonus payment in 1997 for calendar 1996 performance,
until the loan is repaid in full.
