                1998 STOCK OPTION PLAN FOR NONEMPLOYEE DIRECTORS
   (AS AMENDED BY THE BOARD OF DIRECTOR JUNE 7, 1999, AND DECEMBER 12, 2002)


         1. Purpose. The purpose of this Plan is to attract and retain qualified
individuals to serve as nonemployee members of the Board of Directors of HEI,
Inc. (the "Company") and to provide such persons with appropriate incentives.

the approval of the Company's stockholders, and unless extended by amendment in
accordance with the terms of the Plan, no Option Rights will be granted
hereunder after the tenth anniversary of such effective date. Upon the approval
of the adoption of the Plan by the Company's stockholders, the Plan will replace
and supersede the Company's prior Stock Option Plan for Nonemployee Directors
(the "1991 Plan").

granted under this Plan, any Common Shares that were covered by that award shall
again be available for issuance or transfer hereunder; and

                  (b) Upon the full or partial payment of any Option Price by

withholding obligations in connection with any such exercise or any other
payment made or benefit realized under this Plan by the transfer or
relinquishment of Common Shares, there shall be deemed to have been issued or

Option Rights to purchase 10,000 Common Shares, effective as of the date of such

<PAGE>


                  (b) Each grant shall specify an Option Price per Common Share,
which shall equal the Market Value per Share on the Date of Grant.

                  (c) Each grant shall specify the form of consideration to be
paid in satisfaction of the Option Price and the manner of payment of such
consideration, which may include (i) cash in the form of currency or check or
other cash equivalent acceptable to the Company, (ii) nonforfeitable,
unrestricted Common Shares, which are already owned by the Participant, (iii)
any other legal consideration that the Board may deem appropriate, on such basis
as the Board may determine in accordance with this Plan and (iv) any combination
of the foregoing.

                  (d) Any grant may, if there is then a public market for the
Common Shares, provide for deferred payment of the Option Price from the
proceeds of sale through a broker of some or all of the Common Shares to which
the exercise relates.

                  (e) Successive grants may be made to the same Participant
regardless of whether any Option Rights previously granted to the Participant
remain unexercised.

                  (f) Each grant shall specify that the Option Rights awarded
thereby shall become exercisable in full upon the earliest to occur of (i) the
seventh anniversary of the Date of Grant, (ii) the first date after the Date of
Grant on which the Market Value per Share of the Common Shares (as adjusted as
provided in Section 6 of this Plan) equals or exceeds $25.00, (iii) the date of
the Participant's death or Disability, and (iv) the effective date of a Change
in Control.

                  (g) Each grant shall specify whether the Participant must
remain in continuous service with the Company in order for the Option Rights
awarded thereby to become exercisable in full as set forth in Section 4(f)
above.

                  (h) Option Rights granted pursuant to this Section 4 shall be
nonqualified stock options.

                  (i) No Option Right granted pursuant to this Section 4 may be
exercised more than 10 years from the Date of Grant.

                  (j) Each grant shall be evidenced by an agreement, which shall
be executed on behalf of the Company by any designated officer thereof and
delivered to and accepted by the Participant and shall contain such terms and
provisions as the Board may determine consistent with this Plan.

         5. Transferability. No Option Right granted under this Plan may be
transferred by a Participant, except (i) by will or the laws of descent and
distribution, (ii) to one or more members of the Participant's immediate family,
or (iii) to a trust established for the benefit of the Participant and/or one or
more members of the Participant's immediate family. Option Rights granted under
this Plan may not be exercised during a Participant's lifetime except by (i) the
Participant, (ii) a transferee of the Participant described in the preceding
sentence, or (iii) in the event of the legal incapacity of the Participant or
any such transferee, by the guardian or legal representative of the Participant

thereof under state law and court supervision.

         6.       Adjustments.

                  (a) The Board may make or provide for such adjustments in the
number of Common Shares covered by outstanding Option Rights granted hereunder,
the Option Prices per Common Share applicable to any such Option Rights, and the
kind of shares (including shares of another issuer) covered thereby, as the
Board may in good faith determine to be equitably required in order to prevent
dilution or expansion of the rights of Participants that otherwise would result
from (i) any stock dividend, stock split, combination of shares,
recapitalization or similar change in the capital structure of the Company or
(ii) any merger, consolidation, spin-off, spin-out, split-off, split-up,
reorganization, partial or complete liquidation or other distribution of assets,
issuance of warrants or other rights to purchase securities or any other
corporate transaction or event having an effect similar to any of the foregoing.
In the event of any such transaction or event, the Board may provide in
substitution for any or all outstanding awards under this Plan such alternative
consideration as it may in good faith determine to be equitable under the
circumstances and may require in connection therewith the surrender of all
awards so replaced. Moreover, the Board may on or after the Date of Grant
provide in the agreement evidencing any award under this Plan that the holder of
the award may elect to receive an equivalent award in respect of securities of
the surviving entity of any merger, consolidation or other transaction or event
having a similar effect, or the Board may provide that the holder will
automatically be entitled to receive such an equivalent award. The Board may
also make or provide for such adjustments in the maximum numbers of Common
Shares specified in Section 3 of this Plan as the Board may in good faith
determine to be appropriate in order to reflect any transaction or event
described in this Section 6.

                  (b) If another corporation is merged into the Company or the
Company otherwise acquires another corporation, the Board may elect to assume
under this Plan any or all outstanding stock options or other awards granted by
such corporation under any stock option or other plan adopted by it prior to
such acquisition. Such assumptions shall be on such terms and conditions as the
Board may determine; provided, however, that the awards as so assumed do not
contain any terms, conditions or rights that are inconsistent with the terms of
this Plan. Unless otherwise determined by the Board, such awards shall not be
taken into account for purposes of the limitations contained in Section 3 of
this Plan.

         7.       Fractional Shares.  The Company shall not be required to issue
any fractional Common Shares pursuant to this Plan. The Board may provide for
the elimination of fractions or for the settlement thereof in cash.

         8.       Withholding Taxes. To the extent that the Company is required
to withhold federal, state, local or foreign taxes in connection with any
payment made or benefit realized by a Participant or other person under this
Plan, and the amounts available to the Company for the withholding are
insufficient, it shall be a condition to the receipt of any such payment or the
realization of any such benefit that the Participant or such other person make
arrangements satisfactory to the Company for payment of the balance of any taxes
required to be withheld. At the discretion of the Board, any such arrangements
may without limitation include voluntary or mandatory relinquishment of a
portion of any such payment or benefit or the surrender of outstanding Common
Shares. The Company and any Participant or such other person may also make
similar arrangements with respect to the payment of any taxes with respect to
which withholding is not required.


<PAGE>


         9.       Administration of the Plan.

                  (a) This Plan shall be administered by the Board. A majority
of the Board shall constitute a quorum, and the acts of the members of the Board
who are present at any meeting thereof at which a quorum is present, or acts
unanimously approved by the members of the Board in writing, shall be the acts
of the Board.

                  (b) The interpretation and construction by the Board of any
provision of this Plan or any agreement, notification or document evidencing the
grant of Option Rights, and any determination by the Board pursuant to any
provision of this Plan or any such agreement, notification or document, shall be
final and conclusive. No member of the Board shall be liable for any such action
taken or determination made in good faith.

         10.      Amendments and Other Matters.

                  (a) This Plan may be amended from time to time by the Board;
provided, however, that except as expressly authorized by this Plan, no such
amendment shall cause this Plan to cease to satisfy any applicable condition of
Rule 16b-3 without the further approval of the stockholders of the Company.

                  (b) With the concurrence of the affected Participant, the
Board may cancel any agreement evidencing Option Rights or any other award
granted under this Plan. In the event of any such cancellation, the Board may
authorize the granting of new Option Rights or other awards hereunder, which may
or may not cover the same number of Common Shares as had been covered by the
cancelled Option Rights or other award, at such Option Price, in such manner and
subject to such other terms, conditions and discretion as would have been
permitted under this Plan had the cancelled Option Rights or other award not
been granted.

                  (c) This Plan shall not confer upon any Participant any right
with respect to continuance of service with the Board, the Company or any
Subsidiary and shall not interfere in any way with any right that the Company,
its stockholders or any Subsidiary would otherwise have to terminate any
Participant's service at any time.

                  (d) Any award that may be made pursuant to an amendment to
this Plan that shall have been adopted without the approval of the stockholders
of the Company shall be null and void if it is subsequently determined that such
approval was required under the terms of the Plan or applicable law.

                  (e) Unless otherwise determined by the Board, this Plan is
intended to comply with Rule 16b-3 at all times that awards hereunder are
subject to such Rule.
