     Unless contrary instructions are indicated on the proxy, all valid proxies
received pursuant to this solicitation (and not revoked before they are voted)

stockholder specifies a different choice on the proxy, such stockholder's shares
of Common Stock will be voted in accordance with such specifications.

     Any person giving a proxy in the form accompanying this Proxy Statement has
the power to revoke it at any time before its exercise.  A proxy may be revoked
by filing with the Clerk of the Company an instrument revoking it, by presenting
an executed proxy bearing a later date at the Annual Meeting, or by attending
the Annual Meeting and voting in person.

     The cost of soliciting proxies will be borne by the Company.  Solicitations
may be made by mail, personal interview, telephone and/or telegram by Directors,

                               VOTING SECURITIES
                                        
     The total number of authorized shares of capital stock of the Company is
22,500,000, of which 15,000,000 are shares of common stock, $.01 par value (the
"Common Stock"), and 7,500,000 are shares of preferred stock, $.01 par value

7,368,751 were issued and outstanding at April 14, 1998.  Of the shares of
Preferred Stock authorized for issuance, no shares were issued and outstanding
at April 14, 1998.

     Only stockholders of record at the close of business on Tuesday, April 14,
1998 have the right to receive notice of and to vote at the Annual Meeting and
any adjournments thereof.  Each share of Common Stock entitles the holder
thereof to one vote.  Under the Massachusetts Business Corporation Law, the
presence, in person or by proxy, of stockholders holding a majority in interest
of the issued and outstanding shares of Common Stock entitled to vote at the
Annual Meeting is necessary to constitute a quorum.  Abstentions and broker non-
votes are each included for purposes of determining the presence or absence of a
sufficient number of shares to constitute a quorum for the transaction of
business.  With respect to the approval of any particular proposal, abstentions
and broker non-votes are not counted in determining the number of votes cast.


PROPOSAL I.  ELECTION OF DIRECTORS

          It is intended that, unless otherwise indicated thereon, the proxies
received will be voted in favor of the election of the four persons named below
to serve as Directors until the next Annual Meeting of Stockholders and until
their successors shall be elected and shall qualify.  Although it is expected
that each of the nominees will be available for election, if a nominee is not a
candidate at the time the election occurs, it is intended that such proxies will
be voted for the election of a substitute nominee selected by the Board of
Directors, unless the Board chooses to reduce the number of Directors to the
number of nominees then available for election.  In this event, the proxies
would be voted for the reduced number of nominees.  Unless otherwise indicated
on the enclosed Proxy Card, the votes represented by any proxy may be voted at
the discretion of the person or persons voting the proxy.  The four nominees
receiving a plurality of the votes cast by the stockholders represented at the
meeting, in person or by proxy, will be elected as Directors of the Company.

          The following table sets forth the name and age (as of the date of the
Annual Meeting) of the Directors, their principal occupations at present, the
positions and offices, if any, held by each Director with the Company in
addition to the position as a Director, and the period during which each has
served as a Director of the Company.

                        GENERAL INFORMATION RELATING TO
                             THE BOARD OF DIRECTORS
                                        
The Board of Directors

          The business and affairs of the Company are managed by the Board of
Directors. The Board of Directors held four meetings in the fiscal year ended
January 3, 1998.

          It is anticipated that immediately following the Annual Meeting, the
Board of Directors will hold its Annual Meeting of the Board of Directors. At
such meeting, it is anticipated that the current officers of the Company will be
re-elected to serve in their present capacities until the next annual meeting of
the Board of Directors or until their successors are duly elected and qualified.

Committees of the Board of Directors

          The Company had no nominating or compensation committees of the Board
of Directors or committees performing similar functions during the year ended
January 3, 1998.

          The Board of Directors has an Audit Committee, which has general
responsibility for supervision of financial controls as well as accounting and
audit activities of the Company. The Audit Committee has the responsibility to
review annually the qualifications of the Company's independent certified public
accountants, make recommendations to the Board of Directors concerning the
selection of the accountants and review the planning, fees and results of the
accountants' audit. The current members of the Audit Committee are Messrs.
Hatsopoulos and Wellington. The Audit Committee held one meeting during the
fiscal year ended January 3, 1998.

expenses), a fee of $500 per each such meeting participated in by means of

no compensation as members of the Board of Directors.

                                      -4-

 
Indemnification of Officers and Directors

          The Articles provide that no Director of the Company shall be liable
to the Company or its stockholders for monetary damages for any breach of
fiduciary duty, except to the extent such exculpation from liability is not
permitted under Massachusetts law. This provision does not prevent stockholders
from obtaining injunctive or other equitable relief against Directors nor does
it shield Directors from liability under federal or state securities laws. The
By-Laws provide that the Company shall indemnify its Directors and officers to
the full extent permitted by law.

          The Articles provide that a majority vote of each class of stock
entitled to vote will be required for amendments to the Articles or a merger or
consolidation of the Company.

          Under the rules of the Securities and Exchange Commission (the "SEC"),
a person who directly or indirectly has or shares voting power and/or investment
power with respect to a security is considered to be a beneficial owner of the
security. Shares as to which voting power and/or investment power may be
acquired within 60 days are also considered to be beneficially owned under these
rules.

          The following table sets forth certain information regarding the
beneficial ownership of the Company's Common Stock as of March 20, 1998 by (i)
each person (including any "group" as that term is used in Section 13(d)(3) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act")) known by
the Company to be the beneficial owner of more than 5% of the Company's Common
Stock (assuming conversion of all outstanding warrants and convertible debt),
(ii) each current Director and nominee for election as Director, (iii) each
executive officer who received salary and bonus in excess of $100,000 for all
services rendered during the fiscal year ended January 3, 1998 and (iv) all
current Directors and executive officers of the Company as a group. Except as
otherwise provided in the footnotes to this table, the Company believes that the
persons named in this table have voting and investment power with respect to all
the shares of Common Stock indicated.

            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
                                        
          Section 16(a) of the Exchange Act requires the Company's Directors and
executive officers and holders of more than 10% of the Company's Common Stock to
file with the SEC and NASDAQ initial reports of ownership and reports of changes
in ownership of Common Stock and other equity securities of the Company.
Directors, executive officers and holders of more than 10% of the Company's
Common Stock are required by SEC regulations to furnish the Company with copies
of all Section 16(a) forms they file. Based solely on a review of copies of

                          BOARD OF DIRECTORS REPORT ON
                             EXECUTIVE COMPENSATION
                                        
          Decisions regarding cash compensation paid and stock options granted
to the Company's executive officers were made by the full Board of Directors.

EXECUTIVE COMPENSATION POLICY

          The Company's compensation program is designed to attract, motivate,
reward and retain executive personnel capable of making significant
contributions to the long-term success of the Company. During fiscal 1997, the
Company's compensation program consisted of base salary and incentive bonuses.
Base salary provides the foundation for the Company's executive pay; its purpose
is to compensate the executive for performing his or her basic duties.

          Base Salary. Base salaries for the Company's executive officers are
set annually. During fiscal 1997, the Company did not employ a formula approach
that links cash compensation to corporate performance nor did it utilize any
formal survey or other compilation of empirical data on executive compensation
paid by other companies. Instead, executive compensation was determined based on
a number of subjective factors, including individual responsibilities,
performance, contribution and experience, the Company's financial performance as
compared with the prior year; and general economic factors.

          Stock Options. The Company's compensation program also utilizes stock
option awards, which are intended to provide additional incentive to increase
shareholder value. However, no stock options were granted to the executive
officers of the Company during fiscal 1997.


                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
                                        
          The Company utilizes certain administrative resources of Thermo
Electron on an as-needed basis without a formal contract and is charged at
actual cost for such services. The Company paid $3,253 in 1997 for these
services. George N. Hatsopoulos, Ph.D., a Director of the Company, is Chairman
of the Board and Chief Executive Officer of Thermo Electron. Roger D. Wellington
is also a director of Thermo Electron.

          The Company is provided with certain services by Thermo Power
Corporation, a majority-owned subsidiary of Thermo Electron. These services
include data processing services, administrative services and machine shop
services, which are charged to the Company at actual cost. The Company paid
$113,582 in 1997 for these services. As of January 3, 1998, $15,599 was payable
to Thermo Power Corporation and was included in accounts payable in the
accompanying consolidated balance sheets.

          The Company entered into a Convertible Note and Warrant Purchase
Agreement dated as of May 13, 1992, as amended (the "1992 Debt Agreement"),
pursuant to which the Company sold a 4,500,000 8% Convertible Demand Note (the
"1992 Note") to Peter M. Nomikos, Chairman of the Board, President, Chief
Executive Officer and Treasurer of the Company. As of March 29, 1997, the
Company entered into a letter agreement with respect to the forbearance by Mr.
Nomikos of the right to conversion of the principal and accrued interest under
the 1992 Note until May 13, 1999. The principal amount of the 1992 Note is
convertible into Common Stock at 

                                      -10-

 
$3.00 per share. Currently, the aggregate principal amount outstanding under the
1992 Note is $705,000.

          The Company entered into the Amended and Restated Convertible Note
Purchase Agreement (originally dated July 11, 1991) dated as of August 8, 1996,
pursuant to which the Company sold a $500,000 8% Subordinated Convertible Note
(the "1991 Note") due 1998 to Peter M. Nomikos, Chairman of the Board,
President, Chief Executive Officer and Treasurer of the Company. As of March 29,
1997, the Company entered into a letter agreement providing that accrued
interest on such note is convertible on July 31, 1998. The principal amount of
the 1991 Note is convertible into Common Stock at $3.00 per share. Currently,
the aggregate principal amount outstanding under the 1991 Note is $500,000.

          The warrant purchase rights under the 1992 Debt Agreement entitle Mr.
Nomikos to acquire warrants for $0.20, pursuant to which he may purchase shares
of Common Stock at $3.00 per share. Mr. Nomikos (or his assignee) acquired
warrants to purchase 1,417,334 shares of Common Stock in 1996. At December 28,
1996, warrants to purchase an aggregate of 1,417,334 shares of Common Stock were
outstanding. All warrants issued to date are now held by PYC Corporation.

          On February 4, 1997, the Company completed an initial public offering
of 2,000,000 shares of its Common Stock at a price of $8.50 per share. Pursuant
to an option to purchase additional shares of Common Stock to cover over-
allotments, Needham and Company, Inc. and Dain Bosworth Incorporated purchased
an additional 275,000 shares of Common Stock on March 4, 1997. The shares were
registered with the Securities and Exchange Commission pursuant to a
registration statement on Form S-1 (No. 333-14541), which was declared effective
on January 23,1997. The public offering was underwritten by a syndicate of
underwriters led by Needham and Company, Inc. and Dain Bosworth Incorporated.
After deducting underwriting discounts and commissions of $1,353,625 and
expenses of $1,165,021, the Company received net proceeds of $16,818,854.

          Pursuant to a promissory note dated February 21, 1997 (the "Note"),
the Company loaned $80,211.26 to Peter E. Oettinger, Ph.D., Vice President,
Chief Operating Officer and Director of the Company at an interest rate of 5%
per annum. Such promissory note was secured by a pledge of 25,000 shares of the
Company's Common Stock owned by Mr. Oettinger, pursuant to a Pledge Agreement
with the Company dated as of February 21, 1997 (the "Pledge Agreement"). On
February 21, 1998, the Note was renewed for a period of one year at an interest
rate of 6% per annum.


PROPOSAL II.  AMENDMENT OF EQUITY INCENTIVE PLAN

          The Board of Directors has adopted an amendment to the Equity
Incentive Plan (the "Equity Incentive Plan"), subject to approval by the
stockholders, to increase the number of shares of Common Stock covered by the
Equity Incentive Plan to an aggregate of 541,775 shares. The following is a
summary of the material provisions of the Plan.

          On July 17, 1996, the Board of Directors of the Company adopted the
Equity Incentive Plan for employees, officers, Directors and consultants of the
Company and its subsidiaries, and recommended approval of the plan by the
stockholders. The Equity Incentive Plan provides for

                                      -11-

 
grants of incentive stock options to employees (including officers) of the
Company, and for grants of non-qualified stock options to such employees as well
as to Directors and consultants of the Company and its subsidiaries. In
addition, persons eligible to receive non-qualified stock options can be awarded
shares of Common Stock and given the opportunity to purchase shares of Common
Stock. A total of 266,775 shares of Common Stock may be issued under the current
Equity Incentive Plan. As of January 3, 1998, 151,167 stock options have been
granted under the Equity Incentive Plan.

          The Equity Incentive Plan is administered by the Board of Directors of
the Company, which may delegate any or all of its responsibilities to a
Committee of two or more Board members who, if the Company registers any class
of any equity security pursuant to Section 12 of the Exchange Act, must qualify
as non-employee directors within the meaning of Rule 16b-3 adopted pursuant to
the Exchange Act. The plan administrator determines the recipients and terms of
all stock rights granted under the plan, including in the case of all options,
the option price. Except in the case of some incentive stock options, as
described below, the term of all options granted under the plan may not exceed
ten years.

          Special rules apply to incentive stock options. The exercise price of
all incentive stock options granted under the Equity Incentive Plan must be at
least equal to the fair market value of the Common Stock of the Company on the
date of grant. If an incentive stock option is granted to an optionee who owns
stock representing more than 10% of the voting power of the Company's
outstanding capital stock, the exercise price of the option must equal at least
110% of the fair market value of the Common Stock on the date of grant and the
maximum term of the option cannot exceed five years. No incentive stock option
may be transferred by the optionee other than by will or the laws of descent and
distribution, and should the holder of an incentive stock option cease to be
employed by the Company and any of its subsidiaries, he or she (or his or her
estate, personal representative or beneficiary in the event of death) will no
longer be able to exercise the option to the extent of the shares not
exercisable upon termination of employment, and will have a limited period of
time after termination of employment within which to exercise the option (in
general, three months in the case of termination other than by reason of
disability or death, one year in the event of disability, and 180 days in the
event of death, unless the option expires earlier by its terms).

          At the request of an optionee, the plan administrator can take
whatever action is necessary to convert such optionee's incentive stock options
into non-qualified options. Also, an optionee's rights with respect to options
and other rights granted under the Equity Incentive Plan are to be appropriately
adjusted when certain events occur, such as a stock dividend or split, a
recapitalization, or a merger or sale of assets.

          The Board of Directors of the Company has the authority to amend or
terminate the Equity Incentive Plan provided that, in general, no amendment may
alter or impair the rights of a grantee under any option previously granted
without the grantee's consent and stockholder approval must be obtained within
12 months before or after the Board adopts a resolution authorizing certain
actions, including the extension of the expiration date of the Equity Incentive
Plan or the increase in the number of shares reserved for issuance under the
Equity Incentive Plan. Unless sooner terminated, the Equity Incentive Plan will
terminate on July 16, 2006.

                                      -12-

 
          The Company has filed with the Securities and Exchange Commission a
Registration Statement on Form S-8 covering the shares of Common Stock
underlying options granted under the Equity Incentive Plan.

          The Board of Directors believes it is in the interest of the Company
and its stockholders to adopt the proposed amendment to the Equity Incentive
Plan. The increase in shares available for issuance under the Equity Incentive
Plan will assist the Company to continue to attract and retain key personnel and
to strengthen the identity of such personnel's interest with those of the
Company's stockholders. A majority of the votes cast by the stockholders
represented at the meeting, in person or by proxy, is required to approve this
proposal.

          THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE AMENDMENT OF THE
EQUITY INCENTIVE PLAN.


PROPOSAL III.  RATIFICATION OF SELECTION OF AUDITORS

          The Board of Directors has selected the firm of Arthur Andersen LLP,
independent certified public accountants, to serve as auditors for the fiscal
year ending January 2, 1999. Arthur Andersen LLP served as the Company's
auditors for fiscal year 1998. A majority of the votes cast by the stockholders
represented at the meeting, in person or by proxy, is required to approve this
proposal. Representatives of Arthur Andersen LLP will be present at the meeting
to respond to appropriate questions, and they will have an opportunity, if they
desire, to make a statement.

          THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE RATIFICATION OF THE
SELECTION OF ARTHUR ANDERSEN LLP AS AUDITORS.
