                                PROXY STATEMENT

            The enclosed proxy is solicited by the Board of Directors of
       Thermo Sentron Inc. (the "Corporation") for use at the 1997
       Annual Meeting of the Stockholders (the "Meeting") to be held on
       Monday, June 2, 1997, at 1:30 p.m. at The Hyatt Regency Hotel,
       Hilton Head, South Carolina, and any adjournment thereof. The
       mailing address of the executive office of the Corporation is 501
       90th Avenue, N.W., Minneapolis, Minnesota  55433.  This proxy
       statement and the enclosed proxy were first furnished to
       Stockholders of the Corporation on or about May 2, 1997.  
                               VOTING PROCEDURES

            The Board of Directors intends to present to the Meeting the
       election of five directors, constituting the entire Board of
       Directors, as well as one other matter:  a proposal to adopt an
       employees' stock purchase plan and to reserve 50,000 shares of
       common stock of the Corporation, $.01 par value ("Common Stock"),
       for issuance under the employees' stock purchase plan.

            The representation in person or by proxy of a majority of
       the outstanding shares of 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, for the
       management proposal 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 majority of the shares of Common Stock
       present and entitled to vote on the election. For the management
       proposal to adopt the employees' stock purchase plan, the
       affirmative vote of a majority of shares present in person or
       represented by proxy, and entitled to vote on the matter, is
       necessary for approval. Withholding authority to vote for a
       nominee for director or an instruction to abstain from voting on
       the proposal 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 or the
       proposal. With respect to the election of directors and the
       adoption of the employees' stock purchase plan, broker
                                        4

       "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
       April 7, 1997 consisted of 9,875,000 shares of Common Stock. Only
       Stockholders of record at the close of business on April 7, 1997
       are entitled to vote at the Meeting. Each share is entitled to
       one vote.

                               November 1995, and was a vice president
                               of Thermo Electron from September 1994
                               to November 1995.  Mr. Wood also has

                               officer of Thermedics since 1984.  Mr.

                               Corporation.

       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. Noble and Mr. Richman (Chairman).  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. Richman. 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 five times,
       the Audit Committee met once and the Human Resources Committee

       met four 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 $2,000 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
       directors' fees is made quarterly.  Messrs. Armstrong, Ribich and
       Wood 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.
            Deferred Compensation Plan
            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 Thermedics 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 Thermedics or
       25% or more of the outstanding 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 25,000 shares of Common Stock have been reserved for
       issuance under the Deferred Compensation Plan. As of March 1,
       1997, deferred units equal to 971.40 shares of Common Stock were
       accumulated 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 to outside directors as
       additional compensation for their service as directors.  The
                                        8

       Directors Plan provides for the grant of stock options upon a
       director's initial appointment and, beginning in 2000, awards
       options to purchase 1,000 shares annually to outside directors.
       A total of 100,000 shares of Common Stock have been reserved for
       issuance under the Directors Plan.

            Under the Directors Plan, each outside director who joined
       the Board of Directors prior to or during 1996 was granted an
       option to purchase 15,000 shares of Common Stock upon the
       effective date of the Corporation's initial public offering.  The
       size of awards to new directors appointed to the Board of
       Directors after 1996 is reduced by 3,750 shares in each
       subsequent year.  Outside directors who join the Board of
       Directors after 1999 would not receive an option grant upon their
       appointment or election to the Board of Directors, but would be
       eligible to participate in the annual option awards described
       below.  Options evidencing initial grants to directors are
       exercisable six months after the date of grant.  The shares
       acquired upon exercise are 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.
       The restrictions and repurchase rights lapse or are deemed to
       have lapsed in equal annual installments of 3,750 shares per
       year, starting with the first anniversary of the grant date,
       provided the director has continuously served as a director of
       the Corporation or any other Thermo Electron company since the
       grant date.  These options expire on the fifth 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.

            Outside directors will also receive an annual grant of
       options to purchase 1,000 shares of Common Stock, commencing with
       the Annual Meeting of the Stockholders to be held in 2000.  The
       annual grant is made at the close of business on the date of each
       Annual Meeting of the 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 would be
       subject to repurchase by the Corporation at the exercise price if
       the recipient ceased to serve as a director of the Corporation or
       any other Thermo Electron company prior to the first anniversary
       of the grant date.

            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 per share paid
       by third parties in an arms-length transaction prior to the
                                        9

       option grant.  As of March 1, 1997, options to purchase 30,000
       shares had been granted under the Directors Plan, no options had
       lapsed or been exercised, and options to purchase 70,000 shares
       of Common Stock were reserved and available for future grant
       under the Directors Plan as of March 1, 1997. 

       Stock Ownership Policies for Directors
            During 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
       1996, 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 Thermedics, the
       Corporation's parent company, and of Thermo Electron, Thermedics'
       parent company, as of March 1, 1997, 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 and executive officers of the
       Corporation are also directors and executive officers of
       Thermedics or its subsidiaries other than the Corporation, all
       such persons disclaim beneficial ownership of the shares of
       Common Stock owned by Thermedics.

       (5)  As of March 1, 1997, Thermedics beneficially owned

            Thermedics' address is 470 Wildwood Street, Woburn,
            Massachusetts 01888.  As of March 1, 1997, Thermedics had
            the power to elect all of the members of the Corporation's
            Board of Directors.  Thermedics is a majority-owned
            subsidiary of Thermo Electron and therefore, Thermo Electron
            may be deemed a beneficial owner of the shares of Common
            Stock beneficially owned by Thermedics.  Thermo Electron
            disclaims beneficial ownership of these shares.

       (6)  Information regarding the number of shares of the Common
            Stock beneficially owned by Investment Advisers, Inc. is
            based on the most recent Schedule 13G of Investment
            Advisers, Inc. received by the Corporation, which reported
            such ownership as of December 31, 1996.  The address of
            Investment Advisers, Inc. is 3700 First Bank Place, Box 357,
            Minneapolis, Minnesota 55440.  As of December 31, 1996,
            Investment Advisers, Inc. beneficially owned approximately
            5.07% of the outstanding Common Stock.

       Section 16(a) Beneficial Ownership Reporting Compliance
            Section 16(a) of the Securities Exchange Act of 1934
       requires the Corporation's directors and executive officers, and
       beneficial owners of more than 10% of the Common Stock, such as
       Thermedics and its parent company, Thermo Electron, to file with
       the Securities and Exchange Commission initial reports of
       ownership and periodic reports of changes in ownership of the
       Corporation's securities. Based upon a review of such filings,
       all Section 16(a) filing requirements applicable to such persons
       were complied with during 1996, except in the following
       instances.   Mr. Peter Richman, a director of the Corporation,
       filed one Form 4 late reporting one transaction consisting of an
       open market purchase of shares.  Thermo Electron filed six Forms
       4 late, reporting a total of 17 transactions, consisting of 13
       open market purchases of Common Stock , the exercise of two
       options to purchase Common Stock  granted to employees and the
       lapse and cancellation of two such options without exercise.

       executive officer for the last two fiscal years.  No other
       executive officer of the Corporation met the definition of
       "highly compensated" within the meaning of the Securities and
       Exchange Commission's executive compensation disclosure rules. 
        
            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.

       (1)  The options granted during the fiscal year are immediately
            exercisable as of the end of the fiscal year.  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.  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.  The options granted to Mr. Ribich were granted as
            a part of Thermo Electron's stock option program.  These
            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 holder
            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 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 companies and accordingly are
            reported as a percentage of total options granted to
            employees of Thermo Electron and its subsidiaries.

       (1)  All of the options reported outstanding at the end of the
            fiscal year were immediately exercisable as of the end of
            the fiscal year.  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
            any other Thermo Electron company. The granting corporation
            may exercise its repurchase rights within six months after
            the termination of the optionee's employment.  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 granted as a 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 holder 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. 

                   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 Committees of the Board of Directors of its
       parent corporations, Thermo Electron and Thermedics. 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

                                       15
PAGE
<PAGE>

                                                                         



       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 compensation for its executives is assessed by
       comparing it to market data provided by its compensation
       consultant 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 index, the Dow Jones
       Total Return Index for the Diversified Technology Industry Group.
        
            Principles of internal equity are also central to the
       Committee's compensation policies. 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. 
             Base Salary

            Base salaries are intended 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 1996 for the chief
       executive officer and the other named executive officer 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

                                       16
PAGE
<PAGE>

                                                                         



       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, designed
       to measure profitability and contributions to shareholder value,
       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 calendar 1996 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 within the organization. 
        
            The bonuses for named executive officers approved by the
       Committee with respect to 1996 performance in each instance
       exceeded the median potential bonus. 
            Stock Option Program

            The primary goal of the Corporation 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
       parent companies, Thermo Electron and Thermedics, and the other
       majority-owned subsidiaries of Thermo Electron and Thermedics,
       are an important tool in providing incentives for performance
       within the entire organization. 
        
            In determining awards, the Committee considers the average
                                       17

       annual value of all options to purchase shares of the Corporation
       and other companies within the Thermo Electron organization that
       vest in the next five years. (Values are established using a
       modified Black-Scholes option pricing model.) As a guideline, the
       Committee strives to maintain the aggregate amount of net awards
       to purchase shares of Common Stock to all employees over a
       five-year period below 12% of the Corporation's outstanding
       common stock, although other factors such as unusual transactions
       and acquisitions and standards for awards of comparably situated
       companies may affect the number of awards granted. 
        
            Awards are not made annually in conjunction with the annual
       review of cash compensation, but are made periodically. The
       Committee considers total compensation of executives, 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, in
       determining awards.   

       Stock Ownership Policies
            During 1996, the Committee established a stock holding
       policy for executive officers of the Corporation.  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 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 order to assist officers in complying with the policy,
       the Committee also adopted a stock holding assistance plan under
       which the Corporation is 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 1996, Mr.
       Ribich, the Corporation's chief executive officer, and Mr. Luman,
       the Corporation's vice president, finance and operations, each
       received a loan in the principal amount of $75,384 and
       $70,010.70, respectively, under this plan.  See "Relationship
       with Affiliates - Stock Holding Assistance Plan."

            The Committee also 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

                                       18

       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.

       Policy 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 under
       Section 162(m). The annual compensation paid to individual
       executives does not approach the $1 million threshold, and it is
       believed that 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). 

       1996 CEO Compensation

            The salary and bonus of Mr. Ribich are established using the
       same criteria as for the salaries and bonuses for the
       Corporation's other named executive officers.  In determining Mr.
       Ribich's compensation as reported,  the Committee considered,
       among other factors, his contributions and achievement in
       successfully completing an initial public offering of the
       Corporation's Common Stock in March 1996. 

            The Committee awarded to Mr. Ribich options to purchase
       60,000 shares of the Common Stock in fiscal 1996.  This award was
       determined in a manner consistent with awards to other officers,
       as described above.  In addition to stock option awards by the
       Committee, Mr. Ribich may receive awards to purchase shares of
       the common stock of Thermo Electron or Thermedics or any of their
       majority-owned subsidiaries from time to time as part of Thermo
       Electron's stock option program due to his position as a chief
       executive officer of a majority-owned subsidiary of Thermo
       Electron.  The stock option awards to Mr. Ribich in fiscal 1996
       with respect to shares of the common stock of Thermo Fibergen
       Inc. were awarded under this program.  The awards to purchase
       shares of common stock of Thermo Electron and Thermedics granted
       to Mr. Ribich in fiscal 1996 were made by the human resources
       committees of those companies under a program which awards
       options to certain eligible employees annually based on the
       number of shares of the common stock of Thermo Electron or
       Thermedics held by the employee, as an incentive to buy and hold
       such company's shares.

                         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 subsidiaries,
       including the Corporation, which was created by Thermedics Inc.
       From time to time, Thermo Electron and its subsidiaries will
       create other majority-owned subsidiaries as part of its spinout

                                       20

       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
       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
                                       21

       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, 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 revenues for these services for
       calendar 1996. The fee is reviewed annually and may be changed by
       mutual agreement of the Corporation and Thermo Electron.  During
       fiscal 1996, Thermo Electron assessed the Corporation $700,000 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.

            From time to time, the Corporation may transact business
       with other companies in the Thermo Group.  In fiscal 1996, these
       transactions included the following.

            The Corporation acts as a distributor in Europe for process
       measurement instruments manufactured by TN Technologies ("TN"), a
       subsidiary of Thermo Instrument Systems Inc. ("Thermo
       Instrument"), a publicly traded, majority-owned subsidiary of
       Thermo Electron.  In 1996, the Corporation purchased such
       products from TN for $563,000.  In 1996, the Corporation also
       sold meters to TN resulting in revenues of $114,000.

            In 1996, the Corporation received a ten percent (10%)
       commission totaling $69,670 from another subsidiary of Thermo
       Instrument, which the Corporation earned in connection with the
       sale by this subsidiary of one of its CrossBelt Analyzers to an
       Australian-based cement manufacturing company.

            As of December 28, 1996, $24,732,000 of the Corporation's
       cash equivalents were invested pursuant to 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, United States 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.

       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. Lewis J.
       Ribich, the Corporation's chief executive officer, and Mr. M.
       Preston Luman, the Corporation's vice president, each received
       loans in the respective principal amounts of $75,384 and
       $70,010.70 under this plan to purchase 5,200 and 5,800 shares,
       respectively.  These loans are 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.

                               -- PROPOSAL 2 --

              PROPOSAL TO ADOPT AN EMPLOYEES' STOCK PURCHASE PLAN

            The Board of Directors has approved an employees' stock
       purchase plan (the "Stock Purchase Plan") and reserved 50,000
       shares of the Corporation's Common Stock for issuance thereunder,
       subject to Stockholder approval.  The Board of Directors is
       recommending that the Stockholders approve the Stock Purchase
       Plan and the reservation of shares at this Meeting.  The purpose
       of the Stock Purchase Plan is to grant options to purchase shares
       of Common Stock of the Corporation to eligible employees of the
       Corporation.  The Board of Directors believes that the Stock
       Purchase Plan is an important incentive in attracting and
       retaining key personnel, and motivating individuals to contribute
       significantly to the Corporation's future growth and success, and
       in aligning the long-term interest of these individuals with
       those of the Corporation's Stockholders.  Accordingly, the Board
       of Directors acted to adopt the Stock Purchase Plan subject to
       Stockholder approval.
       Summary of the Stock Purchase Plan

            The full text of the Stock Purchase Plan is set forth in
       Attachment A to this proxy statement.  A description of the
       principal features of the Stock Purchase Plan follows, but it is
       qualified in its entirety by reference to the full text.
            Participation; Administration

            All full-time employees and part-time employees working at
       least 20 hours per week and who have been employed for at least
       six months by the Corporation are eligible to participate in the
       Stock Purchase Plan, unless they own more that 5% of the Common
       Stock of the Corporation.  For purposes of determining the term
       of employment, employees are credited with years of continuous
       employment with Thermo Electron or its other subsidiaries
       immediately prior to joining the Corporation.  Options to
       purchase shares of Common Stock of the Corporation may be granted
       from time to time at the discretion of the Board of Directors,
       which also determines the date upon which such options are
       exercisable.  The number of employees potentially eligible to
       participate in the Stock Purchase Plan is approximately 425
       persons.
            Contributions
            A participating employee may purchase stock only through
       payroll deductions. Eligible employees are also permitted to
       participate in the Thermo Electron employees' stock purchase
       plan, which has substantially the same terms as the Stock
       Purchase Plan.  The aggregate amount which may be contributed
       under the Thermo Electron employees' stock purchase plan and the
       Corporation's Stock Purchase Plan may not exceed 10% of the
       employee's gross salary or wages during the year.  The Board of
       Directors may fix the aggregate amount that may be contributed to
       the Stock Purchase Plan each year in its discretion within such

       limitation.  Employees are allowed to decrease,  but not
       increase, the percentage of wages contributed once during the
       Stock Purchase Plan year.  An employee may suspend his or her
       contributions, but then is not permitted to contribute again for
       the remainder of the Stock Purchase Plan year.
            Terms of Options

            The exercise price is fixed on the grant date and is 95% of
       the fair market value for the Common Stock on such date.  On the
       exercise date, participants may elect to use their accumulated
       payroll deductions to purchase shares at the exercise price.
       Participants must agree not to resell the shares so purchased for
       a period of six months following the exercise date.  The options
       are nontransferable, and except in the case of death of the
       employee, may not be exercised if the employee is not still
       employed by the Corporation at the exercise date.  If an employee
       dies, his or her beneficiary may withdraw the accumulated payroll
       deduction or use such deductions to purchase shares on the
       exercise date.  A participant may elect to discontinue
       participation at any time prior to the exercise date and to have
       his or her accumulated payroll deduction refunded together with
       interest on such amount as fixed by the Board of Directors from
       time to time.
            Shares Subject to the Stock Purchase Plan
            The number of shares that are reserved for issuance under
       the Stock Purchase Plan will be 50,000 shares of the
       Corporation's Common Stock, subject to adjustment for stock
       splits and similar events.  The proceeds received by the
       Corporation from exercise under the Stock Purchase Plan will be
       used for the general purposes of the Corporation.  Shares issued
       under the Stock Purchase Plan may be authorized but unissued or
       shares reacquired by the Corporation and held in its treasury.

            Amendment and Termination
            The Stock Purchase Plan shall remain in full force and
       effect until suspended or discontinued by the Board of Directors.
       The Board of Directors may at any time or times amend or review
       the Stock Purchase Plan for any purpose which may at any time be
       permitted by law, or may at any time terminate the Stock Purchase
       Plan, provided that no amendment that is not approved by the
       Stockholders shall be effective if it would cause the Stock
       Purchase Plan to fail to satisfy the requirements of Rule 16b-3
       (or any successor rule) of the Securities Exchange Act of 1934,
       as amended.  No amendment of the Stock Purchase Plan may
       adversely affect the rights of any recipient of any option
       previously granted without such recipient's consent.
            Effective Date of the Stock Purchase Plan
            The Stock Purchase Plan will become effective as of  
       November 1, 1997, provided that it is approved by the
       Stockholders at this Meeting.

       Federal Income Tax Aspects

            Federal income tax is not imposed upon an employee in the
                                       25

       year an option is granted or the year the shares are purchased
       pursuant to the exercise of the option granted under the Stock
       Purchase Plan.  Federal income tax generally is imposed upon an
       employee when he or she sells or otherwise disposes of the shares
       acquired pursuant to the Stock Purchase Plan.  When an employee
       sells or disposes of the shares, if such sale or disposition
       occurs more than two years from the grant date and more than one
       year from the exercise date, then Federal income tax assessed at
       ordinary rates will be imposed upon the amount by which the fair
       market value of the shares on the date of grant or disposition,
       whichever is less, exceeds the amount paid for the shares.  In
       addition, the difference between the amount received by the
       employee at the time of sale and the employee's tax basis in the
       shares, which is equal to the amount paid on exercise of the
       option plus the amount recognized as ordinary income, will be
       recognized as a capital gain or loss.  The Corporation will not
       be allowed a deduction under these circumstances for Federal  
       income tax purposes.  If the employee sells or disposes of the
       shares sooner than two years from the grant date or one year from
       the exercise date, then the employee's entire gain (the
       difference between the fair market value at disposition and the
       amount paid for the shares) will be taxed as ordinary income, and
       the Corporation would be entitled to a deduction equal to that
       amount.

            The closing price per share on the American Stock Exchange
       of the Common Stock on April 25, 1997 was $10.25.

       Recommendation
            The Board of Directors believes that adoption of the Stock
       Purchase Plan and the reservation of shares thereunder is
       important for the Corporation to attract and retain key employees
       and to be able to continue to offer them the opportunity to
       participate in the ownership and growth of the Corporation
       through an employees stock purchase plan.  In addition, the Board
       of Directors believes the Stock Purchase Plan is in the best
       interest of the Corporation and its Stockholders and recommends
       that the Stockholders vote FOR the approval of the Stock Purchase
       Plan and the reservation of 50,000 shares of Common Stock
       thereunder.  Thermedics, which owned of record approximately 70%
       of the outstanding voting stock of the Corporation on April 7,
       1997, has indicated its intention to vote for the proposal.
         
            The affirmative vote of a majority of the Common Stock
       present and entitled to vote on this proposal is required to
       approve the adoption of the Stock Purchase Plan and the
       reservation of 50,000 shares of Common Stock thereunder.  The
       Board of Directors believes that the adoption of the Stock
       Purchase Plan is in the best interest of the Corporation and its
       Stockholders and recommends that you vote FOR approval of the
       Stock Purchase Plan and the reservation of the shares.  If not
       otherwise specified, proxies will be voted FOR approval of this
       proposal.

                 APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

       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.

            Proposals of Stockholders intended to be presented at the
       1998 Annual Meeting of the Stockholders of the Corporation must
       be received by the Corporation for inclusion in the proxy
       statement and form of proxy relating to that meeting no later
       than January 2, 1998. 

                             SOLICITATION STATEMENT
            The cost of this solicitation of proxies will be borne by
       the Corporation. Solicitation will be made primarily by mail, but
       regular employees of the Corporation may solicit proxies
       personally, by telephone, facsimile transmission or telegram.
       Brokers, nominees, custodians and fiduciaries are requested to
       forward solicitation materials to obtain voting instructions from
       beneficial owners of stock registered in their names, and the
       Corporation will reimburse such parties for their reasonable

       no amendment, unless approved by the holders of a majority of the

       if it would cause the Plan to fail to satisfy the requirements of
       Rule 16b-3.  No termination of or amendment to the Plan may
       adversely affect the rights of a Participant with respect to any
       Option held by the Participant as of the date of such termination
       or amendment.

            6.   Shares of Stock Subject to the Plan.  No more than an
       aggregate of 50,000 shares of Company Stock may be issued or
       delivered pursuant to the exercise of Options granted under the
       Plan, subject to adjustments made in accordance with Section 9.8.
       Option Shares may be either shares of Company Stock which are
       authorized but unissued or shares of Company Stock held by the
       Company in its treasury.  If an Option expires or terminates for
       any reason without having been exercised in full, the unpurchased
       Option Shares shall become available for other Options granted
       under the Plan.  The Company shall, at all times during which
       Options are outstanding, reserve and keep available shares of
       Company Stock sufficient to satisfy such Options, and shall pay
       all fees and expenses incurred by the Company in connection
       therewith.  In the event of any capital change in the outstanding
       Company Stock as contemplated by Section 9.8, the number of
       shares of  Company Stock reserved and kept available by the
       Company shall be appropriately adjusted.

            7.   Persons Eligible to Receive Options.  Each employee of

            Corporation.  Employment shall include any leave of absence
            for military service, illness or other bona fide purpose
            which does not exceed the longer of 90 days or the period
            during which the absent employee's reemployment rights are
            guaranteed by statute or contract.

            (b)  The employee is customarily employed by the Company for
                                       30

            more than 20 hours per week and for more than five months
            per calendar year.

            (c)  The employee will not, after grant of the Option, own
            stock possessing five percent or more of the total combined
            voting power or value of all classes of stock of the Company
            or of any Related Corporation.  For purposes of this
            paragraph (c), the rules of Section 425(d) of the Code shall
            apply in determining the stock ownership of the employee,
            and stock which the employee may purchase under outstanding
            options shall be treated as stock owned by the employee.

            (d)  Upon grant of the Option, the employee's rights to
            purchase stock under all employee stock purchase plans (as
            defined in Section 423(b) of the Code) of the Company and
            its Related Corporations will not accrue at a rate which
            exceeds $25,000 of fair market value of the Stock
            (determined as of the Grant Date for such Option) for each
            calendar year in which such Option is outstanding at any
            time.  The accrual of rights to purchase Stock shall be
            determined in accordance with Section 423(b) (8) of the
            Code.

            8.   Dates for Granting Options.  Options shall be granted
       on each date designated by the Board as a Grant Date.

            9.   Terms and Conditions of Options.

            9.1. General.  All Options granted on a particular Grant
       Date shall comply with the terms and conditions set forth in
       Sections 9.3 through 9.12, and each Option shall be identical
       except as to the number of shares of Company Stock purchasable
       under the Option, which shall be determined in accordance with
       Section 9.2.

            9.2. Number of Shares.  The maximum number of shares of
       Company Stock which a Participant shall be permitted to purchase
       shall be equal to the amount of the Participant's Gross
       Compensation permitted to be withheld for purchasing Company
       Stock during the period running from the Grant Date to the
       Exercise Date, divided by the purchase price determined in
       accordance with Section 9.3.  The number of shares which a
       Participant is permitted to purchase may be further limited by
       the amount of payroll deductions actually withheld as of the
       Exercise Date.

            9.3. Purchase Price.  The purchase price of Option Shares
       shall be 95 percent of the Market Value of Company Stock as of
       the Grant Date.  If the Grant Date shall fall on a Saturday,
       Sunday or other legal holiday, the Market Value shall be
       determined as of the trading day immediately preceding the Grant
       Date.

            9.4. Restrictions on Transfer.  Options may not be
                                       31

       transferred otherwise than by will or under the laws of descent
       and distribution, or pursuant to a qualified domestic relations
       order.  An Option may not be exercised by anyone other than the
       Participant during the lifetime of the Participant.  Option
       Shares may not be sold or otherwise transferred by the
       Participant until at least six months after the Exercise Date.
       The Company shall have the right to place a legend on all stock
       certificates representing Option Shares setting forth the
       restriction on transferability of such shares.

            9.5. Expiration.  Each Option shall expire at the close of
       business on the Exercise Date or on such earlier date as may
       result from the operation of Section 9.6.

            9.6. Termination of Employment of Participant. If a
       Participant ceases for any reason, voluntary or involuntary
       (other than death or retirement), to be continuously employed by
       the Company or a Related Corporation, his or her Option shall
       immediately expire, and the Participant's accumulated payroll
       deductions shall be returned by the Company with interest
       pursuant to Section 9.12.  For purposes of this Section 9.6, a
       Participant shall be deemed to be employed throughout any leave
       of absence for military service, illness or other bona fide
       purpose which does not exceed the longer of ninety days or the
       period during which the Participant's reemployment rights are
       guaranteed by statute or by contract.  If the Participant does
       not return to active employment prior to the termination of such
       period, his or her employment shall be deemed to have ended on
       the 91st day of such leave of absence.

            9.7  Retirement or Death of Participant.  If a Participant
       retires or dies, the Participant or, in the case of death, his or
       her Beneficiary, shall be entitled to withdraw the Participant's
       accumulated payroll deductions with interest pursuant to Section
       9.12, or to purchase shares on the Exercise Date to the extent
       that the Participant would have been so entitled had he or she
       continued to be employed by the Company.  The number of shares
       purchasable shall be limited by the amount of the participant's
       accumulated payroll deductions as of the date of his or her
       retirement or death.  Accumulated payroll deductions shall be
       applied by the Company toward the purchase of shares unless the
       Participant or Beneficiary withdraws such funds prior to the
       Exercise Date.

            9.8  Capital Changes Affecting the Stock.  In the event
       that, between the Grant Date and the Exercise Date of an Option,
       a stock dividend is paid or becomes payable in respect of Company
       Stock or there occurs a split-up or contraction in the number of
       shares of  Company Stock, the number of shares for which the
       Option may thereafter be exercised and the price to be paid for
       each such share shall be proportionately adjusted.  In the event
       that, after the Grant Date, there occurs a reclassification or
       change of outstanding shares of Company Stock or a consolidation
       or merger of the Company with or into another corporation or a
                                       32

       sale or conveyance, substantially as a whole, of the property of
       the Company, the Participant shall be entitled on the Exercise
       Date to receive shares of stock or other securities equivalent in
       kind and value to the shares of stock he or she would have held
       if he or she had exercised the Option in full immediately prior
       to such reclassification, change, consolidation, merger, sale or
       conveyance and had continued to hold such shares (together with
       all other shares and securities thereafter issued in respect
       thereof) until the Exercise Date.  In the event that there is to
       occur a recapitalization involving an increase in the par value
       of Company Stock which would result in a par value exceeding the
       exercise price under an outstanding Option, the Company shall
       notify the Participant of such proposed recapitalization
       immediately upon its being recommended by the Board to the
       Company's shareholders, after which the Participant shall have
       the right to exercise his or her Option prior to such
       recapitalization; if the Participant fails to exercise the Option
       prior to recapitalization, the exercise price under the Option
       shall be appropriately adjusted.  In the event that, after the
       Grant Date, there occurs a dissolution or liquidation of the
       Company, except pursuant to a transaction to which Section 425(a)
       of the Code applies, each Option to purchase Company Stock shall
       terminate, but the Participant holding such Option shall have the
       right to exercise his or her Option prior to such dissolution or
       liquidation.

            9.9. Payroll Deductions.  Any Eligible Employee, who wishes
       to authorize payroll deductions for the purchase of Option Shares
       under the Plan, must complete and return to the human resources
       department of the Company prior to the Grant Date an Enrollment
       Agreement indicating the total percentage (which shall be a full
       integer between one and the maximum determined by the Board in
       accordance with Section 4 hereof) of his or her Gross
       Compensation which is to be withheld each pay period.  Prior to
       the Exercise Date, the Participant shall be permitted only once
       to (a) withdraw accumulated payroll deductions, (b) discontinue
       payroll deductions, or (c) decrease, but not increase, the
       percentages of Gross Compensation withheld.  The Participant may
       not recommence payroll deductions at any time prior to the
       Exercise Date.

            9.10.     Exercise of Options.  On the Exercise Date the
       Participant shall be deemed to have exercised his or her Option
       to purchase the maximum number of Option Shares purchasable by
       his or her accumulated payroll deductions, provided that:

            (a)  The number of Option Shares of Company Stock
       purchasable shall not exceed the number of shares the Participant
       is entitled to purchase pursuant to Section 9.2. 

            (b)  If the total number of Option Shares of Company Stock
       which all Participants elect to purchase, together with any
       Option Shares of Company Stock already purchased under the Plan,
       exceeds the total number of shares of Company Stock which may be
                                       33

       purchased under the Plan pursuant to Section 6, the number of
       shares of Company Stock which each Participant is permitted to
       purchase shall be decreased pro rata based on the Participant's
       accumulated payroll deductions with respect to Company Stock in
       relation to all accumulated payroll deductions currently being
       withheld under the Plan with respect to Company Stock.

            (c)  If the number of Option Shares purchasable includes a
       fraction, such number shall be adjusted to the next smaller whole
       number and the purchase price shall be adjusted accordingly.

            (d)  Notwithstanding the foregoing, a Participant may notify
       the Company's human resources department at least 30 days prior
       to an Exercise Date, by completing an Enrollment/Change
       Agreement, that he or she elects not to exercise his or her
       Option and desires to withdraw his or her accumulated payroll
       deductions withheld under the Plan, as provided in Section 9.9.

            9.11.     Delivery of Stock.  Within a reasonable time after
       the Exercise Date, the Company shall deliver or cause to be
       delivered to the Participant a certificate or certificates for
       the number of shares purchased by the Participant.  If any law or
       applicable regulation of the Securities and Exchange Commission
       or other body having jurisdiction in the premises shall require
       that the Company or the Participant take any action in connection
       with the shares being purchased under the Option, delivery of the
       certificate or certificates for such shares shall be postponed
       until the necessary action shall have been completed, which
       action shall be taken by the Company at its own expense, without
       unreasonable delay.  The Participant shall have no rights as a
       shareholder in respect of shares for which he or she has not
       received a certificate.

            9.12.     Return of Accumulated Payroll Deductions.  In the
       event that the Participant or the Beneficiary is entitled to the
       return of accumulated payroll deductions, whether by reason of
       voluntary withdrawal, termination of employment, retirement,
       death, or in the event that accumulated payroll deductions exceed
       the price of Option Shares purchased, such amount, together with
       interest thereon at the rate fixed by the Board of Directors
       (which rate for a particular plan year running from Grant Date to
       Exercise Date shall be fixed annually by the Board of Directors
       prior to the commencement of such period), shall be returned
       within a reasonable time by the Company to the Participant or the
       Beneficiary, as the case may be; provided, however,  that
       interest shall not be paid on any amount returned which is less
       than the purchase price of one Option Share of Company Stock for
       which such payroll deductions were withheld.
