                                        PART I

ITEM 1.  DESCRIPTION OF BUSINESS

(a)  BUSINESS DEVELOPMENT
     HEI, Inc., a Minnesota corporation, was incorporated as Hybrid Electronics
     Inc. in 1968 and changed its name to HEI, Inc. in 1969.

(b)  BUSINESS OF THE COMPANY

     PRINCIPAL PRODUCTS AND SERVICES - HEI, Inc. is a designer and manufacturer
     of ultraminiature microelectronic devices and high technology products
     incorporating these devices.  HEI's custom-built microelectronics are
     employed in medical, industrial and computer markets.  The optical switch
     product line and light pen product line, which represented minor parts of 
     the Company's sales, were sold in August 1997 and August 1996, 
     respectively.

     DISTRIBUTION METHODS - HEI sells through its Company-employed sales force
     based at corporate headquarters.

     SOURCES AND AVAILABILITY OF RAW MATERIALS - There are many sources of raw
     material supplies available nationally and internationally for Company
     operations.  The manufacture of Company products involves assembly of
     components purchased from a wide variety of vendors.  The Company's 
     business is not dependent on any single supplier.

     DEPENDENCE ON SINGLE OR FEW CUSTOMERS - Following is the approximate
     percentage of the Company's sales to major customers which accounted for 
     more than 10% of total sales in fiscal years 1997, 1996 and 1995.


     Customer            1997           1996           1995
     --------            ----           ----           ----
     Customer A          55%            16%
     Customer B          27%            38%            12%
     Customer C                         10%
     Customer D                                        30%
     Customer E                                        27%


                                         -2-
<PAGE>

     COMPETITION - In each of its product lines, the Company has significant
     competition, including users who may produce their own alternative devices.
     The Company obtains new business by identifying customer needs and
     engineering its products to meet those needs.  It competes on the basis of
     engineering expertise, quality, service and price to obtain new and repeat
     orders.

     RESEARCH AND DEVELOPMENT - The estimated amount spent on Company-sponsored
     research and development activities was approximately $843,000 and $849,000
     for the years ended August 31, 1997 and 1996.

     EMPLOYEES - At August 31, 1997, the Company employed approximately 120
     persons of which 2 were part-time.


ITEM 2.  DESCRIPTION OF PROPERTY

The Company owns a 48,000 square foot facility for administration and 
production in Victoria, Minnesota, which was completed in August 1981.  The 
facility was expanded during fiscal 1996 from the original 25,000 square feet 
with an addition of 23,000 square feet to increase production capacity.  Due 
to the sale of the optical switch business in August 1997, the Company no 
longer leases a facility in Sauk Centre, Minnesota.

There are no legal proceedings pending against the Company or its properties.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY-HOLDERS

directors to constitute the Board of Directors (subject to the authority of the
Board of Directors thereafter to increase or decrease the number of directors as
permitted by law), shall elect qualified successors for directors who serve for
an indefinite term or whose terms have expired or are due to expire within six
months after the date of the meeting, and shall transact such other business as
may properly come before them.

    Section 2.03   SPECIAL MEETINGS.  Special meetings of the shareholders may
be held at any time and for any purpose and may be called by the Chief Executive
Officer, Chief Financial Officer, any two directors, or by a shareholder or
shareholders holding 10% or more of the shares entitled to vote (except that a
special meeting for the purpose of considering any action to directly or
indirectly effect a business combination, including any action to change or
otherwise affect the composition of the Board of Directors for that purpose,
must be called by shareholders holding not less than 25% of all shares of the
corporation entitled to vote), who shall demand such special

meeting by written notice given to the Chief Executive Officer or the Chief
Financial Officer of the corporation specifying the purposes of such meeting.

    Section 2.04.  QUORUM, ADJOURNED MEETINGS.  The holders of a majority of
the shares entitled to vote shall constitute a quorum for the transaction of
business at any regular or special meeting.  In case a quorum shall not be
present at a meeting, those present may adjourn to such day as they shall, by
majority vote, agree upon.  If a quorum is present, a meeting may be adjourned
from time to time without notice other than announcement at the meeting.  At
adjourned meetings at which a quorum is present, any business may be transacted
which might have been transacted at the meeting as originally noticed.  If a
quorum is present at the beginning of the meeting, the shareholders may continue
to transact business until adjournment notwithstanding the withdrawal of enough
shareholders to leave less than a quorum.

    Section 2.05.  VOTING.  At each meeting of the shareholders every
shareholder having the right to vote shall be entitled to vote either in person
or by proxy.  Each shareholder, unless the Articles of Incorporation or statute
provide otherwise, shall have one vote for each share having voting power
registered in such shareholder's name on the books of the corporation.  Jointly
owned shares may be voted by any joint owner unless the corporation receives
written notice from any one of them denying the authority of that person to vote
those shares.  Upon the demand of any shareholder, the vote upon any question
before the meeting shall be by ballot.  All questions shall be decided by a
majority vote of the number of shares entitled to vote and represented at the
meeting at the time of the vote except if otherwise required by statute, the
Articles of Incorporation, or these Bylaws.

    Section 2.06.  CLOSING OF BOOKS.  The Board of Directors may fix a time,
not exceeding 60 days preceding the date of any meeting of shareholders, as a
record date for the determination of the shareholders entitled to notice of, and
to vote at, such meeting, notwithstanding any transfer of shares on the books of
the corporation after any record date so fixed.  The Board of Directors may
close the books of the corporation against the transfer of shares during the
whole or any part of such period.  If the Board of Directors fails to fix a
record date for determination of the shareholders entitled to notice of, and to
vote at, any meeting of shareholders, the record date shall be the 20th day
preceding the date of such meeting.

    Section 2.07.  NOTICE OF MEETINGS.  Notice of each shareholders' meeting
shall be mailed to each shareholder, shown by the books of the corporation to be
a holder of record of voting shares, at his address as shown by the books of the
corporation, setting out the time and place of the meeting, except where the
meeting is an adjourned meeting and the date, time and place of the meeting were
announced at the time of adjournment, except that notice of a meeting at which
an agreement of merger or exchange is to be considered shall be mailed to all
shareholders of record, whether entitled to vote or not, at least fourteen days
prior thereto.  Every notice of any special meeting called pursuant to Section
2.03 hereof shall state the purpose or purposes for which the meeting has been
called, and the business transacted at all special meetings shall be confined to
the purpose stated in the notice.

    Section 2.08.  WAIVER OF NOTICE.  Notice of any regular or special meeting
may be waived by any shareholder either before, at or after such meeting orally
or in a writing signed by such


                                          2
<PAGE>

shareholder or a representative entitled to vote the shares of such shareholder.
A shareholder, by his attendance at any meeting of shareholders, shall be deemed
to have waived notice of such meeting, except where the shareholder objects at
the beginning of the meeting to the transaction of business because the item may
not lawfully be considered at the meeting and does not participate in the
consideration of the item at that meeting.

    Section 2.09.  WRITTEN ACTION.  Any action which might be taken at a
meeting of the shareholders may be taken without a meeting if done in writing
and signed by all of the shareholders entitled to vote on that action.

    Section 2.10.  ADVANCE NOTICE REQUIREMENTS.  Only persons who are nominated
in accordance with the procedures set forth in this Section 2.10 shall be
eligible for election as directors.  Nominations of persons for election to the
Board of Directors of the corporation may be made at a meeting of shareholders
(a) by or at the direction of the Board of Directors or (b) by any shareholder
of the corporation entitled to vote for the election of directors at the meeting
who complies with the notice procedures set forth in this Section 2.10.
Nominations by shareholders shall be made pursuant to timely notice in writing
to the Secretary of the corporation.  To be timely, a shareholder's notice must
be delivered to or mailed and received at the principal executive offices of the
corporation not less than 50 days prior to the meeting; provided, however, that
in the event that less than 60 days' notice or prior public disclosure of the
date of the meeting is given or made to shareholders, notice by the shareholder
to be timely must be so received not later than the close of business on the
10th day following the first day on which such notice of the date of the meeting
was mailed or such public disclosure was made.  Such shareholder's notice shall
set forth (x) as to each person whom the shareholder proposes to nominate for
election or re-election as a director, (i) such person's name and (ii) all
information relating to such person that is required to be disclosed in
solicitations of proxies for election of directors, or is otherwise required,
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended
(including such person's written consent to being named in the proxy statement
as a nominee and to serving as a director if elected); and (y) as to the
shareholder giving the notice, (i) the name and address, as they appear on the
corporation's books, of such shareholder and (ii) the class and number of shares
of the corporation which are beneficially owned by such shareholder.  At the
request of the Board of Directors, any person nominated by the Board of
Directors for election as a director shall furnish to the Secretary of the
corporation that information required to be set forth in a shareholder's notice
of nomination which pertains to a nominee.  Notwithstanding anything in these
Bylaws to the contrary, no person shall be eligible for election as a director
of the corporation unless nominated in accordance with the procedures set forth
in this Section 2.10.  The Chairman of the meeting shall, if the facts warrant,
determine and declare to the meeting that a nomination was not made in
accordance with the procedures prescribed in this Section 2.10 and, if the
Chairman should so determine, the Chairman shall so declare to the meeting and
the defective nomination shall be disregarded.

    At any regular or special meeting of shareholders, only such business shall
be conducted as shall have been brought before the meeting (a) by or at the
direction of the Board of Directors or (b) by any shareholder of the corporation
who complies with the notice procedures set forth in this Section 2.10.  For
business to be properly brought before any regular or special meeting by a
shareholder, the shareholder must have given timely notice thereof in writing to
the Secretary of


                                          3
<PAGE>
the corporation.  To be timely, a shareholder's notice must be delivered to or
mailed and received at the principal executive offices of the corporation not
less than 50 days prior to the meeting, provided, however, that in the event
that less than 60 days' notice or prior public disclosure of the date of the
meeting is given or made to shareholders, notice by the shareholder to be timely
must be received not later than the close of business on the 10th day following
the first day on which either such notice of the date of the regular or special
meeting was mailed or such public disclosure was made.  A shareholder's notice
to the Secretary shall set forth as to each matter the shareholder proposes to
bring before the regular or special meeting (w) a brief description of the
business desired to be brought before the meeting and the reasons for conducting
such business at the meeting, (x) the name and address, as they appear on the
corporation's books, of the shareholder proposing such business, (y) the class
and number of shares of the corporation which are beneficially owned by the
shareholder and (z) any material interest of the shareholder in such business.
Notwithstanding anything in these Bylaws to the contrary, no business shall be
conducted at any regular or special meeting except in accordance with the
procedures set forth in this Section 2.10 and, as an additional limitation, the
business transacted at any special meeting shall be limited to the purposes
stated in the notice of the special meeting.  The Chairman of the meeting shall,
if the facts warrant, determine and declare to the meeting that business was not
properly brought before the meeting in accordance with the provisions of this
Section 2.10 and, if the Chairman should so determine, the Chairman shall so
declare to the meeting and any such business not properly brought before the
meeting shall not be transacted.

shall be managed by or under the direction of the Board of Directors, except as
otherwise permitted by statute.

    Section 3.02.  NUMBER, QUALIFICATION AND TERM OF OFFICE.  Until the first
meeting of shareholders, the number of directors shall be the number named in
the Articles of Incorporation or, if no such number is named therein, the number
elected by the incorporator.  Thereafter, the number of directors shall be
established by resolution of the shareholders (subject to the authority of the
Board of Directors to increase or decrease the number of directors as permitted
by law).  In the absence of such shareholder resolution, the number of directors
shall be the number last fixed by the shareholders, the Board of Directors, the
incorporator or the Articles of Incorporation.  Directors need not be
shareholders.  Each of the directors shall hold office until the regular meeting
of shareholders next held after such director's election and until such
director's successor shall have been elected and shall qualify, or until the
earlier death, resignation, removal, or disqualification of such director;
provided, however, that no director shall be elected to a term in excess of five
years.

    Section 3.03.  BOARD MEETINGS.  Meetings of the Board of Directors may be
held from time to time at such time and place within or without the State of
Minnesota as may be designated in the notice of such meeting.

twenty-four hours' notice, or by any other director by giving at least five
days' notice, of the date, time and place thereof to each director by mail,
telephone, telegram or in person.

    Section 3.05.  WAIVER OF NOTICE.  Notice of any meeting of the Board of
Directors may be waived by any director either before, at, or after such meeting
orally or in a writing signed by such director.  A director, by his attendance
at any meeting of the Board of Directors, shall be deemed to have waived notice

meeting to the transaction of business because the meeting is not lawfully
called or convened and does not participate thereafter in the meeting.

    Section 3.06.  QUORUM.  A majority of the directors holding office
immediately prior to a meeting of the Board of Directors shall constitute a
quorum for the transaction of business at such meeting.

    Section 3.07.  ABSENT DIRECTORS.  A director may give advance written
consent or opposition to a proposal to be acted on at a meeting of the Board of
Directors.  If such director is not present at the meeting, consent or
opposition to a proposal does not constitute presence for purposes of
determining the existence of a quorum, but consent or opposition shall be
counted as a vote in favor of or against the proposal and shall be entered in
the minutes or other record of action at the meeting, if the proposal acted on
at the meeting is substantially the same or has substantially the same effect as
the proposal to which the director has consented or objected.

    Section 3.08.  CONFERENCE COMMUNICATIONS.  Any or all directors may
participate in any meeting of the Board of Directors, or of any duly constituted
committee thereof, by any means of communication through which the directors may
simultaneously hear each other during such meeting.  For the purposes of
establishing a quorum and taking any action at the meeting, such directors
participating pursuant to this Section 3.08 shall be deemed present in person at
the meeting, and the place of the meeting shall be the place of origination of
the conference communication.

by a majority of the remaining directors of the Board although less than a
quorum; newly created directorships resulting from an increase in the authorized
number of directors by action of the Board of Directors as permitted by Section
3.02 may be filled by a two-thirds vote of the directors serving at the time of
such increase; and each director elected pursuant to this Section 3.09 shall be
a director until such director's successor is elected by the shareholders at
their next regular or special meeting.

    Section 3.10.  REMOVAL.  Any or all of the directors may be removed from
office at any time, with or without cause, by the affirmative vote of the
shareholders holding a majority of the shares entitled to vote at an election of
directors, except as otherwise provided by Minnesota Statutes Section 302A.223,
as amended, when the shareholders have the right to cumulate their votes.  A
director named by the Board of Directors to fill a vacancy may be removed from
office


                                          5
<PAGE>
at any time, with or without cause, by the affirmative vote of the remaining
directors if the shareholders have not elected directors in the interim between
the time of the appointment to fill such vacancy and the time of the removal.
In the event that the entire Board or any one or more directors be so removed,
new directors shall be elected at the same meeting.

    Section 3.11.  COMMITTEES.  A resolution approved by the affirmative vote
of a majority of the Board of Directors may establish committees having the
authority of the board in the management of the business of the corporation to
the extent provided in the resolution.  A committee shall consist of one or more
persons, who need not be directors appointed by affirmative vote of a majority
of the directors present.  Committees are subject to the direction and control
of, and vacancies in the membership thereof shall be filled by, the Board of
Directors, except as provided by Minnesota Statutes Section 302A.243.

    A majority of the members of the committee present at a meeting is a quorum
for the transaction of business.

    Section 3.12.  WRITTEN ACTION.  Any action which might be taken at a
meeting of the Board of Directors, or any duly constituted committee thereof,
may be taken without a meeting if done in writing and signed by all of the
directors or committee members, unless the Articles provided otherwise and the
action need not be approved by the shareholders.

    Section 3.13.  COMPENSATION.  Directors who are not salaried officers of
this corporation shall receive such fixed sum per meeting attended or such fixed
annual sum as shall be determined, from time to time, by resolution of the Board
of Directors.  The Board of Directors may, by resolution, provide that all
directors shall receive their expenses, if any, of attendance at meetings of the
Board of Directors or any committee thereof.  Nothing herein contained shall be
construed to preclude any director from serving this corporation in any other
capacity and receiving proper compensation therefor.

                                      ARTICLE IV

Directors shall elect or appoint by resolution approved by the affirmative vote
of a majority of the directors present, from within or without their number, the
Chief Executive Officer, Chief Financial Officer, and such other officers as may
be deemed advisable, each of whom shall have the powers, rights, duties,
responsibilities, and terms in office provided for in these Bylaws or a

qualification of their successors, notwithstanding an earlier termination of
their directorship.

    Section 4.03.  REMOVAL AND VACANCIES.  Any officer may be removed from his
office by the Board of Directors at any time, with or without cause.  Such

shall be certificated shares.  Every owner of shares of the corporation shall be
entitled to a certificate, to be in such form as shall be prescribed by the
Board of Directors, certifying the number of shares of the corporation owned by
such shareholder.  The certificates for such shares shall be numbered in the
order in which they shall be issued and shall be signed, in the name of the

suit or proceeding, whether civil, criminal, administrative or investigative,
including a proceeding by or in the right of the corporation (hereinafter a
"proceeding"), by reason of the fact that he or she, or a person for whom he or
she is the legal representative, is or was a director or officer of the
corporation or, while a director or officer of the corporation, is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, where the
basis of such proceeding is alleged action in an official capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the corporation to the fullest extent authorized by the Minnesota Business
Corporation Act, as the same exists or may hereafter be amended (but in the case
of any such amendment, only to the extent that such amendment permits the
corporation to provide broader indemnification rights than said law permitted
the corporation to provide prior to such amendment), by common law or by
administrative or judicial interpretation, against all expense, liability and
loss (including attorneys' fees, expert witness fees, bonds prospective or
retroactive, insurance premiums or costs, out-of-pocket expenses related to a
proceeding, judgments, fines, including without limitation, excise taxes or
penalties assessed against such person with respect to any employee benefit
plan, or amounts paid or to be paid in settlement, including any interest
payable thereon) reasonably incurred or suffered by such person in connection
therewith.  Such indemnification shall continue as to a person who has ceased to
be a director or officer and shall inure to the benefit of his or her heirs,
executors and administrators; provided, however, that except as provided in
Section 9.02 hereof, the corporation shall indemnify any such person seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such person only if such proceeding (or part thereof) was authorized by the
Board of Directors of the corporation.  The right to indemnification conferred
in this Section shall be a contract right and shall include the right to be paid
by the corporation the expenses incurred in defending any such proceeding in
advance of its final disposition; provided, however, that payment of such
expenses in advance of the final disposition of a proceeding shall be made only
upon (i) delivery to the corporation of a written affirmation, by the person
seeking such payment in advance, of a good faith belief that the criteria for
indemnification set forth in the Minnesota Business Corporation Act have been
satisfied, (ii) a determination that the facts then known to those making the
determination would not preclude indemnification under the Minnesota Business
Corporation Act or these Bylaws, and (iii) delivery to the corporation of an
undertaking, by or on behalf of such person, to repay all amounts so advanced if
it shall ultimately be determined that such person is not entitled to be
indemnified under this Section or otherwise.  Such written undertaking to repay
shall be a general obligation of the person making it, shall not be secured, and
shall be accepted without reference to financial ability to make the repayment.
The corporation may, by action of its Board of Directors, provide
indemnification to other classes of employees and agents of the corporation with
the same scope and effect as the foregoing indemnification of directors and
officers.

    Section 9.02.  RIGHT OF CLAIMANT TO BRING SUIT.  If a claim under Section
9.01 of this Article is not paid in full by the corporation within sixty days
after a written claim has been received by the corporation the claimant may at
any time thereafter bring suit against the corporation to recover the unpaid
amount of the claim and, whether or not the claimant is successful in whole or
in part, the claimant shall be entitled to be paid also the expense of


                                          11
<PAGE>
prosecuting such claim.  It shall be a defense to any such action (other than an
action brought to enforce a claim for expenses incurred in defending any
proceeding in advance of its normal disposition where the required undertaking,
if any is required, has been tendered to the corporation) that the claimant has
not met the standards of conduct which make it permissible under the Minnesota
Business Corporation Act for the corporation to indemnify the claimant for the
amount claimed, but the burden of proving such defense shall be on the
corporation.  Neither the failure of the corporation (including its Board of
Directors, Committee for the Board of Directors, special legal counsel, or its
shareholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because claimant met the applicable standard of conduct set forth in the
Minnesota Business Corporation Act, nor an act or determination by the
corporation (including its Board of Directors, Committee of the Board of
Directors, special legal counsel, or its shareholders) that the claimant has not
met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.

    Section 9.03.  NON-EXCLUSIVITY OF RIGHTS.  The right to indemnification and
payment of expenses incurred in defending a proceeding in advance of its final
disposition conferred in this Article IX shall not be exclusive of any other
right which any person may have or hereafter acquire under any statute, common
law or administrative or judicial interpretation, provisions of the Articles of
Incorporation, Bylaws, agreement, vote of shareholders or disinterested
directors, or otherwise.

    Section 9.04.  INSURANCE.  The corporation may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
corporation or another corporation, partnership, joint venture, trust or other
enterprise against any such expense, liability or loss, whether or not the
corporation would have the power to indemnify such person against such expense,
liability or loss under the Minnesota Business Corporation Act.

    Section 9.05.  INDEMNIFICATION AGREEMENTS.  The corporation shall enter
into agreements with its directors further providing the terms and conditions of
their indemnification.

    Section 9.06.  AMENDMENTS LIMITED.  Any amendment to this Article IX shall
only apply prospectively and shall in no way affect the corporation's
obligations to indemnify and make advances pursuant to the Minnesota Business
Corporation Act, this Article IX, or any contract of the corporation for actions
or events which occurred before such amendment.

                                      AMENDMENTS

    Section 10.01.  These Bylaws may be amended or altered by a vote of the
majority of the whole Board of Directors at any meeting, provided that notice of
such proposed amendment shall have been given in the notice given to the
Directors of such meeting.  Such authority in the Board of Directors is subject
to the power of the shareholders to change or repeal such Bylaws by a majority
vote of the shareholders present or represented at any regular or special
meeting of shareholders called for such purpose, and the Board of Directors
shall not make or alter any Bylaws fixing a quorum for meetings of shareholders,
prescribing procedures for removing Directors or filling vacancies in the Board
of Directors, or fixing the number of directors or their classifications,
qualifications, or terms of office, except that the Board of Directors may adopt
or amend any Bylaw to increase its number.

behalf of this corporation.  At such meeting, the President shall possess and
may exercise any and all rights and powers incident to the ownership of such
securities that the corporation possesses.  The Board of Directors may, from
time to time, grant such power and authority to one or more other persons and
may remove such power and authority from the Chief Executive Officer or any
other person.

by the Board of Directors, the Chief Executive Officer shall have full power and
authority on behalf of the corporation to purchase, sell, transfer or encumber

of the Company, and to attract, reward and retain them as directors of the

options to purchase Common Stock of the Company.

defined as set forth below:

     five business days of the closing bid prices of the Stock as reported on

     3.   ADMINISTRATION.  The Plan shall be administered by the Board, which,

more directors appointed by the Board.  The members of any such committee shall
qualify as required under Rule 16b-3 of the Exchange Act, as it may be amended
from time to time.  Grants of Options under the Plan shall be made automatically
as provided in Section 5. However, the Board shall have full authority to
interpret the Plan, to promulgate such rules and regulations with respect to the
Plan as it deems desirable and to make all other determinations necessary or
appropriate for the administration of the Plan, and such determinations shall be
final and binding upon all persons having an interest in the Plan.

     4.   ELIGIBILITY.  Options will be granted only to persons who at the time
of the grant are directors of the Company and who are not otherwise employees of
the Company or any affiliate of the Company ("Nonemployee Director" or
"Nonemployee Directors").

     5.   OPTIONS.

          (a)  ANNUAL GRANT.  Each year, on the first business day following the
     annual meeting of the Company's shareholders (but in no event later than
     April 1 or the first business day thereafter), each person serving on such
     date as a Nonemployee Director of the Company shall be granted an Option to
     purchase Ten Thousand (10,000) shares of Stock.  Except as otherwise may be
     provided herein, each Option (a) shall be subject to all terms of the Plan,
     (b) shall be granted for a term of ten years, and (c) shall vest and become
     fully exercisable on the earlier of the date of the next annual meeting of
     the shareholders or the date one year from the date of grant; provided, in
     each instance, that the Participant has continuously served as a
     Nonemployee Director of the Company during such period or until the
     election of directors next following the date of grant, whichever shall
     first occur (and, if not, said Option shall be forfeited in its entirety).

          (b)  EXERCISE PRICE.  The exercise price per share of  Stock
     purchasable under an Option shall be not less than 100% of the Fair Market
     Value of the Stock on the date of grant.

          (c)  METHOD OF EXERCISE.  Stock Options may be exercised in whole or
     in part at any time during the term of the Option.  Payment of the exercise
     price shall be made by (i) cash or certified bank check, (ii) delivery of
     shares of Stock already owned by the Participant, or (iii) any combination
     of the foregoing.  For purposes of this paragraph, shares of Stock that are
     delivered in payment of the exercise price shall be valued at their

                                        2

<PAGE>

     Fair Market Value as of the date of the exercise of the Option.  The
     Company's obligation to deliver shares upon the exercise of Options shall
     be subject to applicable federal, state, and local tax withholding
     requirements.  Unless otherwise determined by the Board, withholding
     obligations may be settled with Stock, including Stock received as part of
     the exercise giving rise to the withholding requirement.

          (d)  RESTRICTIONS ON TRANSFER OF OPTION.  Unless otherwise provided in
     the related Option Agreement and approved in advance by the Board, each
     Option granted under this Plan shall be transferable only by will or the
     laws of descent and distribution or pursuant to a qualified domestic
     relations order as defined by the Code or Title I of the Employee
     Retirement Income Security Act ("ERISA"), or the rules thereunder.  Except
     as permitted by the preceding sentence, no Option granted under the Plan or
     any of the rights and privileges thereby conferred shall be transferred,
     assigned, pledged, or hypothecated in any way (whether by operation of law
     or otherwise), and no such Option, right, or privilege shall be subject to
     execution, attachment, or similar process. Unless otherwise provided in the
     related Option Agreement and approved in advance by the Board, an Option
     may be exercised during the Participant's lifetime only by the Participant
     or his or her guardian or legal representative.

          (e)  PRIOR GRANTS.  Effective November 19, 1997, all Options then
     outstanding held by currently serving Nonemployee Directors shall be
     extended for an additional five years and shall expire ten years from the
     original date of grant.

     6.   SHARES OF STOCK SUBJECT TO THE PLAN.  There shall be reserved and
available for issuance upon the exercise of Options granted from time to time
under the Plan an aggregate of 400,000 shares of Stock.  Such shares may
consist, in whole or in part, of authorized but unissued shares of Stock or
issued shares that have been reacquired by the Company.  If any shares subject
to an Option are not issued because the Option is not exercised, such shares
shall again be available for distribution in connection with future Options.

     In the event of any merger, reorganization, consolidation,
recapitalization, Stock dividend, Stock split, or other change in corporate
structure affecting the Stock, such substitution or adjustment shall be made in
the aggregate number of shares reserved for issuance under the Plan and in the
number and option price of shares subject to outstanding Options granted under
the Plan as may be determined to be appropriate by the Board, in its sole
discretion, provided that the number of shares subject to any Option shall
always be a whole number.

7.   DEATH OR DISABILITY OF PARTICIPANT.

          (a)  TERMINATION BY DEATH.  If a Participant's service to the Company
     terminates by reason of death, any Stock Option held by such Participant
     will immediately become fully exercisable and may thereafter be exercised
     by the legal representative of the Participant's estate or by any person
     who acquired the Option by will or the laws of descent and distribution for
     a period of one year from the date of such death or until the expiration of
     the stated term of such Stock Option, whichever period is the shorter.

                                        3

<PAGE>

           (b) TERMINATION BY REASON OF DISABILITY.  If a Participant's service
     to the Company terminates by reason of Disability, any Stock Option held by
     such Participant shall immediately become fully exercisable and may
     thereafter be exercised by the Participant until the expiration of the
     stated term of such Stock Option; provided, however, that, if the
     Participant dies prior to the expiration of the Option, any unexercised
     Stock Option held by such Participant shall thereafter be exercisable to
     the extent to which it was exercisable at the time of death for a period of
     one year from the date of such death or until the expiration of the stated
     term of such Stock Option, whichever period is the shorter.

     8.   RESTRICTIONS ON TRANSFER OF STOCK.  Unless a registration statement
under the Securities Act of 1933 is in effect with respect to Stock to be
purchased upon exercise of Options to be granted under the Plan, the Company may
require that the Participant represent to and agree with the Company in writing
that he or she is acquiring such shares of Stock for the purpose of investment
and with no present intention to transfer, sell, or otherwise dispose of such
shares of Stock.  Further, in the absence of such registration, no shares of
Stock acquired pursuant to exercise of an option may be transferred unless, in
the opinion of counsel to the Company, such transfer is in compliance with
applicable securities laws, and each certificate representing any shares of
Stock issued to a Participant hereunder shall have endorsed thereon an
appropriate legend referring to the restrictions against transfer.

     9.   AMENDMENT OF THE PLAN.  The Board of Directors may suspend or
terminate the Plan or any portion thereof at any time, and the Board of
Directors may amend the Plan from time to time as may be deemed to be in the
best interests of the Company; provided, however, that no such amendment,
alteration or discontinuation shall be made (a) that would impair the rights of
a Nonemployee Director with respect to Options theretofore awarded, without such
person's consent, or (b) without the approval of the stockholders (i) if such
approval is necessary to comply with any legal, tax, or regulatory requirement,
including any approval requirement that is a prerequisite for exemptive relief
from Section 16(b) of the Exchange Act; or (ii) to increase the maximum number
of shares of Stock subject to this Plan, increase the maximum number of shares
issuable to any Nonemployee Director under this Plan, or change the definition
of persons eligible to receive Options under this Plan.

     10.  APPLICABILITY OF PLAN TO OUTSTANDING STOCK OPTIONS.  This Plan shall
not affect the terms and conditions of any stock options currently outstanding
to any director of the Company, nor shall it affect any of the rights of any
director to whom such a stock option was granted.

     11.  EFFECTIVE DATE OF PLAN.  This Plan shall become effective upon the
date of its adoption by the Board of Directors of the Company, subject to
approval of the shareholders of the Company at the 1992 annual meeting.

     12.  CHANGE IN CONTROL PROVISIONS.

          (a)  IMPACT OF EVENT. In the event of a "Change in Control" as
     defined in Section 12(b), the following provisions shall apply:

               (i)    All Options granted hereunder shall become fully 
          exercisable and vested.

               (ii)   At the option of the holder thereof, the value of any
          outstanding Option shall be cashed out on the basis of the "Change in
          Control Price" as defined in Section 12(c) as of the date such Change
          in Control is determined to have occurred or such other date as the
          Committee may determine prior to the Change in Control.

          (b)  DEFINITION OF "CHANGE IN CONTROL."  For purposes of Section
     12(a), a "Change in Control" means the happening of any of the following:

               (i)    When any "person" as defined in Section 3(a)(9) of the
          Exchange Act and as used in Sections 13(d) and 14(d) thereof,
          including a "group" as defined in Section 13(d) of the Exchange Act,
          but excluding the Company or any subsidiary or parent or any employee
          benefit plan sponsored or maintained by the Company or any subsidiary
          or parent (including any trustee of such plan acting as trustee),
          directly or indirectly, becomes the "beneficial owner" (as defined in
          Rule 13d-3 under the Exchange Act, as amended from time to time), of
          securities of the Company representing 20 percent or more of the
          combined voting power of the Company's then outstanding securities;

               (ii)   When, during any period of 24 consecutive months during 
          the existence of the Plan, the individuals who, at the beginning of 
          such period, constitute the Board (the "Incumbent Directors") cease 
          for any reason other than death to constitute at least a majority 
          thereof; provided, however, that a director who was not a director 
          at the beginning of such 24-month period shall be deemed to have 
          satisfied such 24-month requirement (and be an Incumbent Director) 
          if such director was elected by, or on the recommendation of, or 
          with the approval of, at least 60% of the directors who then 
          qualified as Incumbent Directors either actually (because they were 
          directors at the beginning of such 24-month period) or by prior 
          operation of this Section 12(b)(ii); or

               (iii)  The approval by the shareholders of an acquisition of
          the Company by an entity other than the Company or a subsidiary or
          parent through purchase of assets, or by merger, or otherwise.

                                        5

<PAGE>

          (c)  CHANGE IN CONTROL PRICE.  For purposes of this Section 12,
     "Change in Control Price" means the highest price per share paid in any
     transaction reported on any market on which the Company's Stock is traded
     or paid or offered in any bona fide transaction related to the Change in
     Control of the Company at any time during the 60-day period immediately
     preceding the occurrence of the Change in Control.

     13.  NONEXCLUSIVITY OF THE PLAN.  The adoption of this Plan shall not be
construed as limiting the power of the Board of Directors to adopt such other
incentive arrangements as it may deem desirable, including, without limitation,
the granting of stock options otherwise than under this Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.

     14.  MISCELLANEOUS.

          (a)  GOVERNING LAW.  This Plan shall be governed by and construed in
     accordance with the laws of the State of Minnesota, and all terms shall be
     interpreted and construed so that there shall not be committed any
     violation of applicable state or federal securities laws.

          (b)  NO ADDITIONAL RIGHTS OF SERVICE.  Participation in or eligibility
     for participation in the Plan does not grant any person any right of
     service as a director, and the Company retains the right to terminate
     service of any director pursuant to the Company's Articles, Bylaws, and
     applicable law.

          Company's outstanding stock; or

               (v)    during any period of two consecutive years, individuals
          who at the beginning of such period constitute the entire Board of

          shareholders, of each new director was approved by a vote of at least

          limit the time periods during which Executive and others shall not

          increase Executive's base salary (within 12 months of Executive's last
          increase in base salary) after a Change in Control of the Company in

          enjoyed by Executive at the time of a Change in Control of the
          Company;

          Company (or any other plans or arrangements providing him with
          substantially similar benefits) (hereinafter referred to as "Incentive
          Plans") or the taking of any action by the Company which would
          adversely affect Executive's participation in any

                                        4

<PAGE>

          such Incentive Plan, expressed as a percentage of his base salary, by
          more than ten percentage points in any fiscal year as compared to the
          immediately preceding fiscal year;

               (v)    Any failure by the Company to continue in effect, or to
          provide a comparable substitute for, any plan or arrangement to
          receive securities of the Company (including, without limitation, any
          stock option plan or any other plan or arrangement to receive and
          exercise stock options, stock appreciation rights, restricted stock,
          or grants thereof) in which Executive is participating, or is eligible
          to participate, at the time of a Change in Control of the Company (or
          plans or arrangements providing him with substantially similar
          benefits) (hereinafter referred to as "Securities Plans") or the
          taking of any action by the Company which would adversely affect
          Executive's participation in or materially reduce Executive's benefits
          under any such Securities Plan;

               (vi)   If at the time of a Change in Control of the Company
          Executive is employed at the Company's principal executive offices, a
          relocation of such principal executive offices to a location more than
          fifty miles outside of the Minneapolis-St. Paul Metropolitan Area or,
          if Executive is not employed at the Company's principal executive
          offices, Executive's relocation to any place other than the location
          at which the Executive performed Executive's duties prior to a Change
          in Control of the Company, except for required travel by Executive on
          the Company's business to an extent substantially consistent with
          Executive's business travel obligations at the time of a Change in
          Control of the Company;

               (vii)  Any failure by the Company to provide Executive with at
          least the number of paid vacation days to which the Executive is
          entitled at the time of a Change in Control of the Company;

               (viii) Any material breach by the Company of any provision of
          this Agreement;

               (ix)   Any failure by the Company to obtain the assumption of
          this Agreement by any successor or assign of the Company; or

               (x)    Any purported termination of Executive's employment which
          is not effected pursuant to a Notice of Termination satisfying the
          requirements of Section 1(g) hereof.

     (g)  "Notice of Termination" shall mean a written notice which shall
          indicate those specific termination provisions in this Agreement
          relied upon and which sets forth in reasonable detail the facts and
          circumstances claiming to provide a basis for termination of the
          Executive's employment under the

                                        5

<PAGE>

          provisions so indicated.  Any termination by the Company pursuant to
          this Agreement shall be communicated by Notice of Termination.  For
          purposes of this Agreement, no such purported termination by the
          Company shall be effective without such Notice of Termination.

     2.   TERM.  This Agreement shall become effective immediately upon
execution and shall be in effect until August 31, 1998, and shall be renewed
automatically for each subsequent one-year period unless either the Executive or
the Company gives written notice to the other party on or before the June 1st
immediately preceding the expiration date, or, if a Change in Control has
occurred, this Agreement shall be in effect for a period of two (2) years
following the date of the Change in Control.

     3.   SEPARATE EMPLOYMENT ARRANGEMENTS.  Executive is, and shall be,
employed by the Company solely upon the existing arrangements which are separate
from this Agreement, as those employment arrangements hereafter may be amended
by the parties.  The parties expressly acknowledge and agree that this Agreement
is not intended to be an employment agreement.

     4.   PARTICIPATION IN OTHER EXECUTIVE BENEFIT PLANS.  Nothing in this
Agreement shall in any manner modify, impair, or affect the existing or future
rights or interests of Executive (a) to receive any employee benefits from the
Company to which he would otherwise be entitled or (b) as a participant in any
incentive, profit-sharing or bonus plan, stock option plan or pension plan of
the Company.  The rights and interests of Executive to any employee benefits or
as a participant or beneficiary in or under any or all such plans shall continue
in full force and effect.  Executive shall have the right at any future time to
become a participant or beneficiary under or pursuant to any and all such plans.
Any compensation payable under this Agreement shall not be deemed salary or
other compensation to Executive for purposes of any retirement plans maintained
by the Company or for purposes of any other fringe benefit obligations of the
Company.

     5.   NONASSIGNABILITY OF BENEFITS.  Executive shall not transfer, assign,
encumber, or otherwise dispose of his right to receive payments hereunder and,
in the event of any attempted transfer or assignment, the Company shall have no
further liability to Executive under this Agreement.

     6.   PAYMENTS AND BENEFITS UPON A CHANGE IN CONTROL.  If Executive is
employed by the Company upon the occurrence of a Change in Control, the
following provisions shall govern:

               (a)    The Executive shall continue to be employed for twenty-
          four (24) months with substantially the same duties, compensation, and
          benefits in the same geographic location as existed just prior to the
          Change in Control.

                                        6

<PAGE>

               (b)    The Executive may terminate his employment during the
          twenty-four (24) months following the Change in Control for Good
          Reason as defined herein, and, upon such termination, shall receive
          from the Company in a lump sum, in cash, on the fifth (5th) day
          following the Date of Termination, an amount equal to two (2) times
          the Executive's "annualized includable compensation for the base
          period" (as defined in Section 280G(d) of the Internal Revenue Code of
          1986, as amended (the "Code")), but, in any event, the Executive shall
          not engage in Competitive Activities for two years following the Date
          of Termination and shall not divulge at any time Confidential
          Information about the Company.

               (c)    If the Company terminates the Executive's employment other
          than for Cause as defined herein, the Executive shall receive as
          severance pay in a lump sum, in cash, on the fifth (5th) day following
          the Date of Termination, an amount equal to two (2) times the
          Executive's "annualized includable compensation for the base period"
          (as defined in Section 280G(d) of the Code), but, in any event, the
          Executive shall not engage in Competitive Activities for two years
          following the Date of Termination and shall not divulge at any time
          Confidential Information about the Company.

               (d)    The Executive may terminate his employment upon at least
          three months' notice at the end of the first twelve (12) months of
          employment after the Change in Control for other than Good Reason,
          thereby waiving any further benefits hereunder except a severance
          benefit of three months salary and a prorated portion of annual bonus,
          provided that the Executive then agrees not to hire or attempt to hire
          any employee of the Company during the twelve (12) month period
          following the termination of employment, but, in any event, the
          Executive shall not divulge at any time any Confidential Information
          about the Company.

               (e)    If the Executive terminates his employment during the 24-
          month period following the change in Control otherwise than under any
          of paragraphs (b) or (d) of this Section 6, the Executive shall not be
          entitled to any payments for any period after the end of the
          employment, shall not receive any severance benefit, and shall not
          engage in any Competitive Activities during the balance of the twenty-
          four (24) month period, but, in any event, the Executive shall not
          divulge at any time any Confidential Information about the Company.

               (f)    If the Executive holds any options to purchase stock of
          the Company after a Change in Control, such options shall become
          immediately exercisable in full and the Executive shall be entitled to
          exercise such options until the expiration date provided for in the
          related stock option agreement.

                                        7

<PAGE>

               (g)    If the lump sum severance payment provided for under this
          Section 6, calculated as set forth above, either alone or together
          with other payments which the Executive has the right to receive from
          the Company, would constitute an "excess parachute payment" (as
          defined in Section 280G of the Code), such lump sum severance payment
          shall be reduced to the largest amount as will result in no portion of
          the lump sum severance payment under this Section 6 being subject to
          the excise tax imposed by Section 4999 of the Code.  The determination
          of any reduction in the lump sum severance payment under this Section
          6(g) pursuant to the foregoing sentence shall be made by the Executive
          in good faith, and such determination shall be conclusive and binding
          on the Company.

               (h)    In the event of termination of Executive's employment
          under paragraph (b), (c), or (d) of this Section 6, Executive shall be
          entitled to continue to participate in the Company's group medical,
          dental, life and disability plans on the same basis as Executive
          participated immediately prior to the Notice of Termination for a
          period of two (2) years following the Date of Termination.  Executive
          shall be responsible for payment of premiums to the same extent as
          prior to the Notice of Termination.  In the event that Executive
          becomes eligible for or obtains substantially equivalent coverage from
          another source, the Company's obligation under this paragraph 6(h)
          shall terminate.

     7.   ENTIRE AGREEMENT; HEADINGS.  This Agreement is the entire Agreement
between the parties on its subject matter and shall be deemed to supersede any
other agreements allegedly made between the parties regarding the subject
matter.  The parties represent that no other such agreements or understandings
exist.  Headings shall not be utilized in any interpretation of this Agreement.

     8.   RESOLUTION OF DISPUTES.  Any dispute or claim arising out of this
Agreement, or breach thereof, shall be decided by arbitration, under the
commercial arbitration rules of the American Arbitration Association ("AAA"),
and shall be conducted in the Minneapolis, Minnesota, metropolitan area.  This
agreement to arbitrate shall be specifically enforceable.  Any decision rendered
by the arbitrator shall be final and binding, and judgment may be entered upon
it by any court having jurisdiction.  Nothing herein contained shall bar either
party from seeking equitable remedies in a court of appropriate jurisdiction.

     9.   NOTICES.  Any notice or other communication provided for herein or
given hereunder shall be in writing and shall be delivered in person or, in the
case of the Company, to the Board of Directors, or mailed by first class
registered or certified mail, postage prepaid, addressed to the Company at its
registered office in the State of Minnesota and addressed to the Executive or
any other person at the last known address of such person appearing on the books
of the Company.

     10.  AMENDMENT.  This Agreement may not be changed, modified or amended
except in writing signed by both parties.

     11.  WAIVER OF BREACH.  The waiver by either party of the breach of any
provision of this Agreement shall not operate or be construed as a waiver of any
subsequent breach by either party.

     12.  INVALIDITY OF ANY PROVISION.  The provisions of this Agreement are
severable, it being the intention of the parties hereto that should any
provisions hereof be invalid or unenforceable, such invalidity or
unenforceability of any provision shall not affect the remaining provisions
hereof, but the same shall remain in full force and effect as if such invalid or
unenforceable provision or provisions were omitted.

     13.  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon, and
inure to the benefit of, the Company, its successors and assigns, and Executive,
his heirs, legal representatives and assigns.

     14.  GOVERNING LAW.  This Agreement is being delivered and is intended to
be performed in the State of Minnesota and shall be construed and enforced in
accordance with the laws of such state.

     15.  COUNTERPARTS.  This Agreement may be executed simultaneously in two or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute but one and the same instrument.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.

TO OUR SHAREHOLDERS


Fiscal year 1997 was a year of growth for HEI.  We achieved record annual
revenue and net income results, and ended the year with an even stronger balance
sheet.  Revenue for fiscal year 1997 was $30,962,000, compared to $20,680,000
for fiscal 1996.  Net income for fiscal 1997 was $2,550,000, or $.60 per share,
compared to net income of $2,113,000, or $.52 per share, for 1996.  Revenue for
the fourth quarter of fiscal 1997 was $6,440,000, compared to revenue of
$6,397,000 for the fourth quarter of the previous year, but down from revenue of
$9,067,000 for the third quarter of fiscal 1997.  Net income for the fourth
quarter just ended was $410,000, or $.10 per share, compared to net income for
the fourth quarter of fiscal 1996 of $1,329,000, or $.32 per share, including a
one-time favorable deferred tax adjustment of $.07.

     Also during the fourth quarter of this past year, we completed the sale of
HEI's optoelectronic switch assembly business and related assets located at Sauk
Centre, Minnesota, thereby closing out activities at this site.  The net gain
after tax on this sale contributed approximately $.03 per share to fourth
quarter earnings.  Since the revenue from this segment was less than 5% of HEI's
total for the 1997 fiscal year, we expect the sale to have minimal impact on
future earnings.

     As has been characteristic of our custom design and manufacturing business,
growth may be interrupted periodically by a hiatus either to effect expansion or
to concentrate on the replacement of phased-out programs.  The ramp-down of a
large program in the fourth quarter of fiscal 1995 resulted in a downturn in
revenue and profit for that period and the ensuing three quarters of fiscal
1996.  Similarly, in the fourth quarter of fiscal 1997 we experienced a phase-
out of the high volume disk drive program that represented about 55% of our
fiscal 1997 revenue.  As stated previously, we anticipate significantly
decreased fiscal 1998 quarterly revenue and operating income compared to 1997
quarterly results until equivalent replacement business is secured.  We have
placed a high priority on gaining new business, and are confident that our
current marketing activities will lead to significant new growth opportunities.

     HEI's financial strength and stability continues to grow, enhancing our
ability to weather the storms of adverse business circumstances, and enabling
the Company to take advantage of a broader range of expansion opportunities as
they may arise.  Fiscal 1997 closed with a record Shareholders' Equity of
$16,995,000, and a Current Ratio of 6.7:1.

1998 PLANS

     In addition to our continuing efforts to replace business and resume
growth, we will strive to increase stability in operations and performance
through a broadening of markets served and/or through expansion of technologies
and process capabilities.  We intend to advance our depth of knowledge and
experience in the diverse materials, substrates and interconnect techniques that
can contribute to our competence and reputation as a state-of-the-art
ultraminiature microelectronics packaging specialist.  We anticipate that
continuing trends favoring miniaturization, and outsourcing will create
increased potential for small-scale implementations such as flip chip, ball grid
array and chip scale packages. Further, we believe that applications in medical
instrumentation--including implantables--and telecommunications represent
emerging growth opportunities for HEI.

     During the past year we installed and initiated operation of a flexible
high volume, continuous flow manufacturing capability, thereby enhancing our
productivity on large volume contracts.  It is our goal to take advantage of
this capability and expanded capacity to develop an improved balance of large
and medium volume manufacturing activities.

     We have been fortunate to serve exceptional customers who have allowed us
to do our best work.  The entire team at HEI offers sincere thanks to our
customers, employees, shareholders and friends for your ongoing support.

ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

FINANCIAL CONDITION

The Company's net cash flow provided by operating activities for the year ended
August 31, 1997, was $4,869,000.  The significant components of this operating
net cash flow were positive cash flow of $3,883,000 from operations before
changes in current operating items and a $1,701,000 decrease in accounts
receivable.  The decrease in accounts receivable is attributable primarily to
lower shipment volumes in the last month of the current fiscal year versus the
same period of last fiscal year.

     Accounts receivable average days outstanding were 36 days as of August 31,
1997 compared to 41 days for the same period a year ago.  Inventory turns were
10.9 turns and 7.7 turns as of August 31, 1997 and 1996, respectively.

     The Company increased short-term investments, primarily in commercial
paper, to $9,175,000, up $3,687,000 from a year ago.  The current ratio at the
end of 1997 was 6.7:1 as compared to 4.4:1 at the end of last year.  The
improved current ratio is principally due to increased cash and cash equivalents
and short-term investments partially offset by decreased accounts receivable.

     In April 1996, the Company completed a new financing agreement which
provides for a $3,000,000 revolving line of credit.  As of August 31, 1997,
there were no borrowings under the line.  Borrowings under this agreement would
be collateralized by accounts receivable.  The agreement contains certain
restrictive covenants including limitations on other borrowings and maintenance
of specified financial levels and ratios for net income, tangible net worth and
debt to tangible net worth.  Borrowings would be limited to the lesser of
$3,000,000 or the borrowing base, which is 80% of eligible accounts receivable.
Interest on the borrowings is based, at the Company's option, on the lender's
prime rate of interest or 2% above the lender's LIBOR rate.

     During fiscal 1997, the Company purchased $1,605,000 of property and
equipment to increase manufacturing capacity to meet anticipated requirements.
These expenditures were funded primarily from the proceeds of the Industrial
Development Revenue Bonds issued in April 1996.  Restricted cash of $389,000 at
August 31, 1997 represents the unexpended funds from the bonds which are
available to the Company for qualifying capital expenditures during the next two
years.

     During fiscal 1998, the Company intends to expend approximately $1.4
million for manufacturing facility improvements and capital equipment.  These
additions will increase manufacturing capacity to meet anticipated requirements
for continued revenue growth.  It is expected that these expenditures will be
funded primarily from internally generated funds and the remaining funds
available from the Industrial Development Revenue Bonds.

- --------------------------------------------------------------------------------

SALES.  1997 VS. 1996:  Sales in 1997 increased $10,282,000, or 50%, over fiscal
1996.  This increase was due to shipments in the high density disk drive
business, primarily to one customer. Shipments to this customer constituted
55% of sales during fiscal year 1997.

     Because the Company's sales to the computer disk drive market are generally
tied to the customers' projected sales and production of the related product,
the Company's sales levels are subject to fluctuations outside the Company's
control.  To the extent that sales to any one customer represent a significant
portion of the Company's sales, any change in the level of sales to that
customer can have a significant impact on the Company's total revenues.  In
addition,

<PAGE>

production for one customer may conclude while production for a new customer has
not yet begun or is not yet at full volume.  These factors may result in
significant fluctuations in sales from quarter to quarter.

     In April 1997, the Company announced that it had received notice from its
then largest current customer to begin phasing out production of a
microelectronic assembly used in high density disk drives.  Phase out of this
program commenced late in the third quarter of this year and was complete by the
end of the fourth quarter.  The phase out is expected to result in significantly
decreased revenues and operating income in fiscal 1998 compared to fiscal 1997
until equivalent replacement business is secured.

     1996 VS. 1995:  Sales in 1996 decreased $2,743,000, or 12%, from fiscal
1995.  Sales of microelectronic circuits, which include the optoelectronic
switch assembly business, decreased 12% from $21.2 million to $18.5 million.
This decrease was primarily due to reduced shipments to the high density disk
drive market as two large programs were completed in late 1995 and early 1996
and was partially offset by the ramp up in the late second half of fiscal 1996
of shipments to another computer disk drive manufacturer.  Shipments to the
hearing aid and other medical markets more than doubled over fiscal year 1995 as
a result of increased demand by current customers and shipments to new accounts.

     Shipments of peripheral products, primarily light pens, decreased 4% from
fiscal 1995.  The light pen product line was sold to FTG Data Systems in August
1996.

- --------------------------------------------------------------------------------

GROSS PROFIT.  1997 VS. 1996:  The Company's gross profit as a percentage of
sales was 21% in 1997, compared to 28% in 1996.  The reduced gross profit rate
was primarily the result of volume pricing to a customer resulting in lower
gross margin rates for sales on a high density disk drive program.

     1996 VS. 1995:  The Company's gross profit as a percentage of sales was 28%
in 1996, compared to 26% in 1995.  The increased gross profit rate reflects
primarily the impact of a higher number of products built utilizing customer
supplied materials.

OPERATING EXPENSES.  1997 VS. 1996:  Selling, general and administrative
expenses decreased 3% in fiscal year 1997 from the prior fiscal year primarily
due to the sale of the light pen product line at the end of fiscal year 1996 and
the leveraging effects of a significantly higher sales level.  Research,
development and engineering expenses remained fairly constant in fiscal year
1997 versus fiscal year 1996.

     Gain on sale of product line of $215,000 in fiscal year 1997 represents the
gain on the sale of the optoelectronic switch assembly business in August 1997.
The $45,000 net gain on sale of product line in 1996 represents the gain on the
sale of the light pen product line, which was completed in August 1996,
partially offset by costs to close down the light pen product line (see Note 3
of Notes to Financial Statements).

     1996 VS. 1995:  Fiscal year 1996 selling, general and administrative
expenses decreased 2% from 1995 and research, development and engineering
expenses increased 13%.  The decrease in selling, general and administrative
expense was primarily due to a reduction in bad debt expense in 1996.  The
increase in research, development and engineering was primarily in support of
increased product development for new disk drive, hearing aid and medical
products.  As a percentage of sales, selling, general and administrative
expenses for fiscal 1996 increased to 11% versus 10% for fiscal 1995, reflecting
decreased sales.

<PAGE>

OTHER, PRINCIPALLY INTEREST INCOME.  1997 VS. 1996:  Other income increased
$191,000 or 75% from fiscal year 1996 primarily due to increased interest income
from significantly higher short-term investment balances, partially offset by
higher interest expense on the Industrial Development Revenue Bonds.

     1996 VS. 1995:  Other income increased $11,000 over fiscal year 1995
primarily due to increased interest income from higher short-term investment
balances, partially offset by interest expense on the Industrial Development
Revenue Bonds.

NET INCOME.  1997 VS. 1996:  The Company had net income of $2,550,000 for 1997
compared to net income of $2,113,000 for 1996.  Operating income of $3,533,000
was up $956,000 from 1996 reflecting the significant 1997 sales increase.  The
effective tax rate for fiscal year 1997 was 36% versus 25% in fiscal year 1996.
The reduced rate in fiscal year 1996 was due to the elimination of a deferred
tax asset valuation allowance.

     1996 VS. 1995:  The Company had net income of $2,113,000 for 1996 compared
to net income of $2,040,000 for 1995. Operating income of $2,577,000 was down
$428,000 from 1995, reflecting the decrease in sales of $2,743,000.  The
increase in net income was primarily due to lower income tax expense.  The
valuation allowance for the deferred tax asset of $274,000 was eliminated in the
fourth quarter of 1996 as a result of the sale and disposal of the light pen
inventory and the determination that the deferred tax assets related to the
remaining inventory allowance will most likely be recoverable.  The elimination
of the remaining deferred tax asset valuation allowance resulted in a reduced
effective tax rate in fiscal 1996.  The effective tax rate for fiscal 1996 was
25% versus 37% for 1995.

ISSUES AND UNCERTAINTIES

This Annual Report contains forward-looking statements that are based on the
Company's current expectations and involve a number of risks and uncertainties.
Factors that may materially affect revenues, expenses and operating results
include, without limitation, adverse business or market conditions, the ability
of the Company to secure and satisfy customers, the availability and cost of
materials from suppliers, adverse competitive developments, and change in or
cancellation of customer requirements.

     The forward-looking statements included herein are based on current
assumptions that the Company will continue to develop, market, manufacture and
ship products on a timely basis, that competitive conditions within the
Company's markets will not change materially or adversely, that the Company will
continue to identify and satisfy customer needs for products and services, that
the Company will be able to retain and hire key personnel, that its equipment,
process, capabilities and resources will remain competitive and compatible with
the current state of technology, that risks due to shifts in customer demand
will be minimized, and that there will be no material adverse change in the
Company's operations or business.  Assumptions relating to the foregoing involve
judgments that are based on incomplete information and are subject to many
factors that can materially affect results.  The Company operates in a volatile
segment of high technology markets and applications that are subject to rapid
change and technical obsolescence.

     Because of these and other factors affecting the Company's operating
results, past financial performance should not be considered an indicator of
future performance, and investors should not use historical trends to anticipate
results or trends in future periods.  The following factors also may materially
affect results and therefore should be considered.

SUBSTANTIAL FLUCTUATIONS IN FUTURE OPERATING RESULTS:  The Company has
experienced substantial fluctuations in its annual and quarterly operating
results, and such fluctuations are expected to continue in future periods.  The
Company's operating results are affected by a number of factors, many of which
are beyond the Company's control.  All products manufactured by the Company are
custom designed and assembled for a specific customer's requirement in
anticipation of the receipt of volume production orders from that customer,
which may not always materialize to the degree anticipated, if at all.  The
Company typically incurs significant start-up costs in the production of a
particular product, which costs are expensed as incurred and for which the
Company attempts to seek reimbursement from the customer.  Accordingly, the

<PAGE>

Company's level of experience in manufacturing a particular product and its
efficiency in minimizing start-up costs will affect the Company's operating
results during the periods in which production begins and ramp-up occurs.  The
efficiencies of the Company in managing inventories and fixed assets, shortages
of components or labor, the degree of automation used in the assembly process,
fluctuations in material costs and the mix of materials, labor, manufacturing,
and overhead costs are also significant factors affecting annual and quarterly
operating results.  Other factors contributing to fluctuations in the Company's
operating results include unforeseen design or manufacturing problems, price
competition, functional competition (other means of accomplishing the same or
similar packaging end result), the inability to pass on cost overruns, the
timing of expenditures in anticipation of increased sales, customer product
delivery requirements, and the range of services provided.  In addition, the
amount and timing of orders placed by a customer may vary due to a number of
factors, including inventory balancing, changes in manufacturing strategy, and
variation in product demand attributable to, among other things, product life
cycles, competitive factors, and general economic conditions.  Any one of these
factors, or a combination thereof, could adversely affect the Company's annual
and quarterly results of operations.

     The Company's customers generally require short delivery cycles, and a
substantial portion of the Company's backlog is typically scheduled for delivery
within 90 days.  Quarterly sales and operating results therefore depend in large
part on the volume and timing of bookings received during or immediately prior
to the quarter, which are difficult to forecast in advance of that time.  The
short lead time for the Company's backlog also affects its ability to accurately
plan production and inventory levels.  In addition, a significant portion of the
Company's operating expenses are relatively fixed in nature and planned
expenditures are based in part on anticipated orders.  Any inability to adjust
spending quickly enough to compensate for any revenue shortfall may magnify the
adverse impact of such revenue shortfall on the Company's results of operations.

DEPENDENCE ON SINGLE INDUSTRY:  During the past several years, the Company's
principal market has been the hard disk drive ("HDD") industry.  In addition,
the Company has made significant sales in the medical products industry, with
emphasis on hearing instrument manufacturers, and is expanding its sales efforts
to include industrial and telecommunications applications.  Each of these
industries is characterized by intense competition, relatively short product
life cycles, rapid technological change, significant fluctuations in product
demand, and significant pressure on vendors to reduce or minimize cost.
Although the Company is attempting to reduce its dependence on any single
industry, the Company does not expect this historic dependence to change
dramatically or quickly.  Accordingly, the Company will likely be affected by
trends in the industries it serves.

CUSTOMER CONCENTRATION:  The Company's customer base is highly concentrated.  In
fiscal 1997 and 1996, the Company's two largest customers accounted for 82% and
54%, respectively, of net sales.  Although the Company is attempting to reduce
its dependence on a limited number of customers, the Company expects that sales
to a relatively small number of original equipment manufacturers ("OEMs") will
continue to account for a substantial portion of net revenues for the
foreseeable future, and the loss of, or a decline in orders from, one of the
Company's key customers would have a material adverse effect on the Company's
financial and operating results.

COMPETITION:  The Company operates in a highly competitive industry and competes
against several domestic and foreign providers of similar microelectronics
design and/or manufacturing services.  The Company also faces competition from
the internal operations of its current and potential OEM customers, which the
Company believes will continue to evaluate the merits of manufacturing
components internally versus outsourcing, and from offshore contract
manufacturers, which, because of their lower labor rates and other related
factors, enjoy a comparative advantage over the Company with respect to high-
volume production.  The Company expects to encounter future competition from
other electronics manufacturers that currently provide or may begin to provide
contract design and manufacturing services.  A

<PAGE>

number of the Company's competitors may have substantially greater
manufacturing, financial, technical, marketing, and other resources than does
the Company, and may offer a broader scope and presence of operations on a
worldwide basis.

     Significant competitive factors in the high density HDD assembly market,
for example, include price, quality, responsiveness, testing capabilities, the
ability to manufacture in very high volumes and proximity to the customers final
assembly facilities.  While the Company has competed favorably in the recent
past with respect to these factors, this is a particularly fast changing market,
and there can be no assurance that the Company will continue to do so in the
future.  The trends toward increasingly shorter product cycles and to off-shore
production are expected to result in more intense competition as each new
customer program is generally open to bidding by the Company and its
competitors, increasingly including those with off-shore facilities and
capabilities.  Further, the Company is often only one of two or more suppliers
on any particular customer requirement and is therefore subject to continuing
competition on existing programs.  In order to remain competitive in any of its
markets, the Company must continually provide timely and technologically
advanced design capabilities and manufacturing services, ensure the quality of
its products, and compete favorably with respect to turnaround and price.  If
the Company were to fail to compete favorably with respect to the principal
competitive factors in its markets served, the Company's business and operating
results would be adversely affected.

COMPONENT SUPPLY AND SOURCES:  Substantially all of the Company's manufacturing
services are provided on a turnkey basis in which the Company, in addition to
providing design, assembly and testing services, is responsible for the
procurement of the components that are assembled by the Company for its
customers.  Although the Company attempts to minimize margin erosion as a result
of component price increases, in certain circumstances it is required to bear
some or all of the risk of such price fluctuations, which could adversely affect
the Company's profits.  To date, the Company has generally been able to
negotiate contracts that allow it to shift much of the impact of price
fluctuations to the customer; however, there can be no assurance that the
Company will be able to do so in all cases.  In addition, in order to assure an
adequate supply of certain key components that have long procurement lead times,
such as integrated circuits, the Company occasionally must order such components
prior to receiving formal customer purchase orders for the assemblies that
require such components.  Failure to accurately anticipate the volume or timing
of customer orders can result in component shortages or excess component
inventory, which in either case could adversely affect the Company's financial
and operating results.

     Some of the assemblies manufactured by the Company require one or more
components that are ordered from, or which may be available from, only one
source or a limited number of sources.  Delivery problems relating to components
purchased from any of the Company's key suppliers could have a material adverse
impact on the financial performance of the Company.  From time to time, the
Company's suppliers allocate components among their customers in response to
supply shortages.  In some cases, supply shortages will substantially curtail
production of all assemblies using a particular component.  In addition, at
various times there have been industry-wide shortages of electronic components.
While the Company has not experienced sustained periods of shortages of
components in the recent past, there can be no assurance that substantial
component shortages will not occur in the future.  Any such shortages could have
a material adverse effect on the Company's operating results.

VARIABILITY OF CUSTOMER REQUIREMENTS AND CUSTOMER FINANCING:  The level and
timing of orders placed by customers vary due to the customers' attempts to
balance their inventory, changes in customers' manufacturing strategies, and
variations and demand for the customers' products.  Due in part to these
factors, most of the Company's customers do not commit to firm production
schedules for more than several weeks in advance of requirements.  The Company's
inability to forecast the level of customers' orders with certainty makes it
difficult to schedule production and optimize utilization of manufacturing
capacity.  In the past, the Company has been required to increase staffing and
incur other expenses in order to meet the anticipated demands of its customers.
From time to time, anticipated orders from some of the Company's

<PAGE>

customers have failed to materialize and delivery schedules have been deferred
as a result of changes in a customer's business needs, both of which have
adversely affected the Company's operating results.  On other occasions,
customers have required rapid increases in production that have placed an
excessive burden on the Company's resources.  There can be no assurance that the
Company will not experience similar fluctuations in customer demand in the
future.  In addition, the Company may carry significant accounts receivable in
connection with providing manufacturing services to its customers.  Although the
Company has not encountered significant problems in collecting on such accounts
receivable on a timely basis, if one or more of the Company's principal
customers were to become insolvent, or otherwise fail to pay for the services
and materials provided by the Company, the Company's operating results and
financial condition would be adversely affected.

RAPID TECHNOLOGICAL CHANGE:  The Company's customers compete in markets that are
characterized by rapid technological change and short product life cycles.  In
particular, the HDD, medical and telecommunications markets are prone to rapid
product obsolescence by new technologies.  The microelectronics industry could
experience future competition from new or emerging technologies that render
existing technology less competitive or obsolete.  The inability of the Company
to develop technologies or acquire capability to meet the evolving market
requirements of its customers could have a material adverse effect on the
Company's business, financial condition and results of operations, including the
Company's ability to maintain its revenue base.

MANAGEMENT OF GROWTH:  The Company has a recent history of growth, sometimes
followed by significant decreases in revenues as customer demands for the
Company's products decrease.  The Company's future operating results will depend
on management's ability to manage periods of both growth and downturn, to be
able to hire, train and retain the appropriate number of qualified employees,
and to forecast revenues and control expenses.  Unexpected declines in revenues,
without corresponding and timely reductions in expenses, could have a material
adverse effect on the Company's business, results of operations, or financial
condition.

HIRING AND RETENTION OF EMPLOYEES:  The Company's continued growth and 
success depend to a significant extent on the continued service of senior 
management and other key employees and the hiring of new qualified employees. 
Competition for skilled business, product development, technical and other 
personnel is intense. There can be no assurance that the Company will be 
successful in recruiting new personnel and retaining existing personnel.  
None of the Company's employees are subject to a long-term employment 
agreement, although several key employees are subject to noncompetition 
agreements.  The loss of one or more key employees could have a material 
adverse effect on the growth of the Company.

POSSIBLE VOLATILITY OF STOCK PRICE:  The market price of the Company's Common
Stock has experienced significant fluctuations and may continue to fluctuate in
the future.  The market price of the Common Stock may be significantly affected
by factors such as changes in requirements or demands for the Company's
services, the announcement of new products or product enhancements by the
Company or its competitors, technological innovations by the Company or its
competitors, quarterly variations in the Company's or its competitors' results
of operations, changes in prices of the Company's or its competitors' products
and services, changes in revenue and revenue growth rates of the Company,
changes in earnings estimates by market analysts, speculation in the press or
analyst community, and general market conditions or market conditions specific
to particular industries.  The stock prices for many companies in the technology
sector have experienced wide fluctuations that often have been unrelated to
their operating performance.  Such fluctuations may adversely affect the market
price of the Company's Common Stock.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
HEI, Inc. (the Company) specializes in the design and manufacture of
ultraminiature microelectronic devices and high technology products
incorporating those devices.

CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS.  The Company considers its
investments in all highly liquid debt instruments with original maturities of
three months or less at date of purchase to be cash equivalents.  The carrying
amount approximates fair value because of the short maturity of those
instruments.  Short-term investments consist mainly of U.S. Treasury bills and
high quality commercial paper with maturities of less than one year.  The short-
term investments are carried at amortized cost which approximates fair value.

     The Company had $3,094,000 and $1,282,000 of cash and cash equivalents at
August 31, 1997 and 1996, respectively, invested with an affiliate of a single
banking institution.

INVENTORIES.  Inventories are stated at the lower of cost or market and include
materials, labor and overhead costs.  The first-in, first-out cost method is
used to value inventories.

     The allowance for excess or obsolete stock is determined based on the
Company's continuing analysis of inventory levels in excess of current
requirements or considered to be obsolete.  The Company has established an
allowance to record such inventories at estimated net realizable value.

PROPERTY AND EQUIPMENT.  Property and equipment are stated at cost.
Depreciation and amortization are provided on the straight-line method over the
estimated useful lives of the property and equipment.

     Maintenance and repairs are charged to expense as incurred.  Major
improvements and tooling costs are capitalized and depreciated over their
estimated useful lives.  The cost and accumulated depreciation of property and
equipment retired or otherwise disposed of are removed from the related
accounts, and any resulting gain or loss charged or credited to operations.

INCOME TAXES.  Deferred income tax assets and liabilities are recognized for the
expected future tax consequences of events that have been included in the
financial statements or tax returns.  Deferred income tax assets and liabilities
are determined based on the differences between the financial statement and tax
bases of assets and liabilities using currently enacted tax rates in effect for
the year in which the differences are expected to reverse.  Valuation allowances
are established when necessary to reduce deferred tax assets to the amount
expected to be realized.  Income tax expense is the tax payable for the periods
and the change during the period in deferred income tax assets and liabilities.

REVENUE RECOGNITION.  Revenue is recognized at the time of shipment.

NET INCOME PER COMMON SHARE.  Net income per common share is based on the
weighted average number of common and common equivalent shares outstanding,
assuming the exercise of stock options, when dilutive.

     In February 1997, Statement of Financial Accounting Standards No. 128 (SFAS
No. 128), Earnings per Share (EPS) was issued by the Financial Accounting
Standards Board.  This standard, which the Company must adopt effective with its
second quarter of fiscal 1998, requires dual presentation of basic and diluted
EPS on the face of the statement of operations.  Net income per common share
currently presented by the Company is comparable to the diluted EPS required
under SFAS No. 128.  Basic EPS for the Company would be calculated based on only
weighted average common shares outstanding without considering the dilutive
effects of common stock equivalents.

<PAGE>

USE OF ESTIMATES.  The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of expenses during the reporting period.
Actual results could differ from those estimates.

     The Company generally sells its products to original equipment
manufacturers in the United States and abroad in accordance with supply
contracts specific to certain manufacturer product programs.  The Company
performs ongoing credit evaluations of its customers' financial conditions and,
generally, does not require collateral from its customers.  The Company's
continued sales to these customers is often dependent upon the continuance of
the customers' product programs.  Customer A's product program was completed
during the fourth quarter of fiscal 1997.  The Company's ten largest customers
accounted for approximately 95% of net sales in 1997, 88% in 1996, and 89% in
1995 and approximately 87% and 90% of accounts receivable at August 31, 1997 and
1996, respectively.

     The Company had net sales of $14,970,000 to Thailand in 1997, $6,647,000
and $5,924,000 to Singapore in 1997 and 1996, respectively, and $2,493,000 to
Hong Kong in 1995.  Net export sales were $22,604,000, $7,278,000 and $4,995,000
in 1997, 1996 and 1995, respectively.  The majority of the international sales
were to multinational companies who instructed HEI to ship products to their
off-shore assembly facilities.

SALE OF PRODUCT LINES.  In August 1997 and 1996, the Company sold its
optoelectronic switch assembly and light pen product lines, respectively.
Through these transactions, the buyers acquired certain assets including
manufacturing equipment and related inventory, product licenses and assumed all
warranties.  In connection with these sales, the Company received cash payments
for the assets and an agreement for additional amounts to be paid monthly over
the subsequent two years.  At August 31, 1996, as a result of the sale of the
light pen product line, costs associated with the close down of this product
line were accrued and were included in the $45,000 net gain from the sale of
product line.  The Company anticipates no substantial effect of the sale of
these product lines on future operating results.

NOTE 4
- --------------------------------------------------------------------------------
FINANCING ARRANGEMENTS

In April 1996, the Company received proceeds of $5,625,000 from the issuance of
Industrial Development Revenue Bonds.  Of these funds, approximately $1,500,000
was used for the construction of the new addition to the Company's manufacturing
facility, and the remainder will be or has been used for equipment purchases.
The bonds related to the facility expansion require annual principal payments of
$90,000 in the first year and $95,000 on April 1 of each year thereafter through
2011.  The bonds related to the purchased equipment require payments over seven
years from the date of purchase of the equipment through no later than April 1,
2006.  In April 1997 the Company repaid $440,000 of the construction and
equipment bonds.  The bonds bear interest at a rate which varies weekly, based
on comparable tax exempt issues, and is limited to a maximum rate of 10%.  The
interest rate at August 31, 1997 was 3.75%.  The bonds are collateralized by two
irrevocable letters of credit and essentially all property and equipment.  A
commitment fee is paid annually to the bank at a rate of 1% of the letters of
credit.  The letter of credit reimbursement agreement contains certain
restrictive covenants including limitations on other borrowings and maintenance
of specified financial levels and ratios for net income, tangible net worth,
debt to tangible net worth, cash flow and indebtedness.  Restricted cash on the
balance sheet represents cash advanced under the bonds which is held by the bond
trustee in an interest bearing account and will be released to the Company over
the next two years for equipment purchases.  To the extent such funds are not
expended, they will revert back to the bond holders.

     Also in fiscal 1996, the Company extended the due date of its $3,000,000
revolving line of credit to April 1998.  At August 31, 1997 and 1996, there were
no borrowings under the line of credit.  Any borrowings under this agreement
would be collateralized by accounts receivable.  The agreement contains certain
restrictive covenants including limitations on other borrowings and maintenance
of specified financial levels and ratios for net income, tangible net worth and
debt to tangible net worth and cash flow.  The agreement also includes a
covenant which limits the sale of assets not in the ordinary course of business.
In accordance with the agreement, the Company received waivers for the sale of
each product line.  Borrowings are limited to the lesser of $3,000,000 or the
borrowing base, which is 80% of eligible accounts receivable.  Interest on the
borrowings is based, at the Company's option, on the lender's prime rate of
interest or at 2% above the lender's LIBOR rate.

     Principal maturities of long-term debt, excluding the unexpended funds
classified as restricted cash, at August 31, 1997 are as follows (in thousands):

     In fiscal 1996, the Company eliminated the valuation allowance of $274,000
for the deferred tax asset related to the allowance established for excess or
obsolete inventories due to the sale and disposal of light pen inventories
during the fourth quarter of fiscal 1996 and the determination that the deferred
tax asset related to the remaining inventory allowance will most likely be
recoverable.

STOCK BENEFIT PLANS

<PAGE>
1989 PLAN.  Under the Company's 1989 Omnibus Stock Compensation Plan (the "1989
Plan"), a maximum of 1,200,000 shares of common stock may be issued pursuant to
qualified and nonqualified stock options, stock purchase rights and other stock-
based awards.

     Stock options granted become exercisable in varying increments and
generally expire five years after date of grant.  The exercise price for options
granted is equal to the average closing market price of the common stock for the
five days preceding the date of grant.

     Under the 1989 Plan, substantially all regular full-time employees are
given the opportunity to designate up to 10% of their annual compensation to be
withheld, through payroll deductions, for the purchase of common stock at 85% of
the lower of (i) the market price at the beginning of the plan year, or (ii) the
market price at the end of the plan year.  During fiscal 1997, 1996 and 1995,
12,049, 26,330 and 22,077 shares at prices of $5.08, $3.96 and $3.95,
respectively, were purchased under the 1989 Plan.

DIRECTORS' PLAN.  Under the directors' plan, 400,000 shares are authorized for
issuance, with an annual grant of 10,000 shares to each non-employee director.
These grants are effective on the first business day following the annual
shareholders' meeting at an exercise price equal to the average closing market
price of the common stock for the five days preceding the date of grant.  The
options become exercisable one year after the grant date and expire five years
after the grant date.  Options to purchase 40,000 shares were granted each year
to the four non-employee directors at $11.325 per share, $6.00 per share and
$4.71 per share in 1997, 1996 and 1995, respectively.  At August 31, 1997,
options for 155,000 shares remain outstanding and 160,000 shares are available
for grant.

ACCOUNTING FOR STOCK-BASED COMPENSATION.  In October 1995, the Financial
Accounting Standards Board issued Statement of Financial Accounting Standards
No. 123, a new standard of accounting and reporting for stock-based compensation
plans.  The Company has adopted the disclosure provisions of the new standard in
fiscal 1997.  The Company has continued to measure compensation cost, if any,
for its stock option plans using the intrinsic value based method of accounting
it has historically used and, therefore, the new standard has no effect on the
Company's operating results.

     Had the Company used the fair-value-based method of accounting for its
stock option plans beginning in fiscal year 1996 and charged compensation cost
against income over the vesting period, net income for fiscal years 1997 and
1996 would have been reduced to the following pro forma amounts:

- --------------------------------------------------------------------------------
                                                     1997           1996
- --------------------------------------------------------------------------------
Net income                                        $2,384,000     $2,023,000

Net income per share                                 $.56           $.49
- --------------------------------------------------------------------------------

     The weighted-average grant-date fair value of options granted during 1997
and 1996 was $5.59 and $2.92, respectively.  The weighted average grant-date
fair value of options was determined separately for each grant under the
Company's various plans by using the fair value of each option grant on the date
of grant, utilizing the Black-Scholes option-pricing model and the following key
assumptions:

- --------------------------------------------------------------------------------
                                                    1997            1996
- --------------------------------------------------------------------------------
Risk-free interest rates                       6.00% TO 6.35%  5.22% to 6.31%
Expected life                                   .5 TO 5 YEARS   .5 to 5 years
Expected volatility                                  62%             58%
Expected dividends                                  NONE            None
- --------------------------------------------------------------------------------

RIGHTS PLAN.  The Company's shareholder rights plan provides for a dividend
distribution of one right for each share of common stock to shareholders of
record at the close of business on June 10, 1988.  With certain exceptions, the
rights will become exercisable only in the event that an acquiring party
accumulates 20% or more of the Company's voting stock or a party announces an
offer to acquire 30% or more of the voting stock.  The rights will expire on
June 10, 1998, if not previously redeemed or exercised.  Each right will entitle
the holder to purchase one-fourth of one common share at a price of $6.00 per
share, subject to adjustment under certain circumstances.  In addition, upon the
occurrence of certain events, holders of the rights will be entitled to purchase
a defined number of shares of an acquiring entity or the Company's common stock
at half its then current market value.   The Company will generally be entitled
to redeem the rights at $.05 per right at any time until the tenth day following
the acquisition of 20% or more or an offer to acquire 30% or more of the
Company's voting stock.

EMPLOYEE BENEFIT PLANS

The Company has a 401(k) plan covering all eligible employees.  Employees can
make voluntary contributions to the plan of up to 20% of their compensation, not
to exceed the maximum specified by the Internal Revenue Code.  The plan also
provides for a discretionary

<PAGE>

contribution by the Company.  During fiscal years 1997, 1996 and 1995, the
Company contributed $100,000, $96,000 and $75,000, respectively, to the plan.



REPORT OF INDEPENDENT ACCOUNTANTS

TO THE SHAREHOLDERS OF HEI, INC.:
We have audited the accompanying balance sheet of HEI, Inc. as of August 31,
1997 and 1996, and the related statements of operations, changes in
shareholders' equity, and cash flows for the years ended August 31, 1997, 1996
and 1995.  These financial statements are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation.  We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of HEI, Inc. as of August 31, 1997
and 1996, and the results of its operations and its cash flows for the years
ended August 31, 1997, 1996 and 1995, in conformity with generally accepted
accounting principles.

<PAGE>

The Company maintains a system of internal accounting controls designed to
provide reasonable assurance that the Company's assets are protected and that

benefit derived.

the independent accounting firm to be retained for the coming year.  The Audit
Committee meets periodically and privately with the independent accountants, as
well as with management, to review accounting, auditing, and financial reporting
matters.
