                              AMENDED AND RESTATED
                          HELIX TECHNOLOGY CORPORATION
                  STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS

1.       PURPOSE

         The purpose of the Helix Technology Corporation Stock Option Plan for
Non-Employee Directors (the "Plan") is to attract and retain the services of
experienced and knowledgeable Directors of Helix Technology Corporation (the
"Corporation") for the benefit of the Corporation and its stockholders and to
provide additional incentives for such Directors to continue to serve the best
interests of the Corporation and its stockholders through continuing ownership
of its common stock.

2.       SHARES SUBJECT TO THE PLAN

         The total number of shares of common stock, par value $1.00 per share
(the "Common Stock"), of the Corporation which may be issued pursuant to options
granted under the Plan (including options granted under the Plan prior to the
date of this amendment and restatement ("Prior Options")) shall not exceed
200,000 in the aggregate (the "Shares"), subject to adjustment in accordance
with Section 9 hereof. Shares for which options have been granted pursuant to
the Plan, but which options have lapsed or otherwise terminated or been canceled
to any extent prior to full exercise, shall become available for additional
options granted under the Plan.

3.       ADMINISTRATION OF PLAN

         The Plan shall be administered by the Human Resources and Compensation
Committee of the Board of Directors (the "Board") or such other committees as
the Board may appoint satisfying the requirements of requirements to qualify for
an exemption under Rule 16b-3 under the Securities Exchange Act of 1934 (the
"Committee"). The Committee shall appoint a person (the "Plan Administrator") to
keep records of all elections of Directors and the grant, vesting and exercise
of all options, and the sale or other disposition of all Shares acquired
pursuant to such exercise.

         Grants of stock options under the Plan shall be made by the Committee
as provided in Section 4. All questions of interpretation with respect to the
Plan and options granted under it shall be determined by the Committee, and such
determination shall be final and binding upon all persons having an interest in
the Plan.

         The Committee shall have the power to (i) make all determinations
necessary or advisable for administering the Plan, (ii) correct any defect or
supply any omission or reconcile any inconsistency in the Plan or in any stock
option grant in the manner and to the extent that the Committee shall deem
expedient to carry it into effect, and (iii) constitute and appoint a person or
persons to execute and deliver in the name and on behalf of the Corporation all
such grants, agreements, instruments and other documents. It is the intent of
this Plan that it operate in all events subject to approval of the Plan by the
stockholders of the Corporation and that the granting and vesting of such
options under it be within the authority of the Committee in accordance with the
terms of this Plan, subject to the authority, discretion or power of the
stockholders to fail to elect an

                                      1

<PAGE>

optionee to the Board of Directors of the Corporation, or to remove an optionee
from the Board of Directors of the Corporation, or to amend or terminate this
Plan.

4.       GRANT OF OPTIONS

         (a) ANNUAL OPTION GRANT. Upon the conclusion of each regular annual
meeting of the Corporation's stockholders held in the year 2002 or thereafter,
each Director of the Corporation who is not otherwise an employee of the
Corporation or any of its subsidiaries (a "Non-Employee Director") who will
continue serving as a member of the Board thereafter and who does not hold Prior
Options which have not yet vested, shall be granted an Option to acquire 2,000
shares under the Plan (the "Annual Option").

         (b) INITIAL OPTION GRANT. Any Non-Employee Director of the Corporation
who is elected for the first time otherwise than at an annual meeting after the
2002 meeting shall receive an initial Option to acquire 2,000 shares under the
Plan (the "Initial Option") which shall become exercisable as of the date of the
annual meeting following such Non-Employee Director's election. The Non-Employee
Director shall be eligible to receive Annual Options as described in Section
4(a).

         (c) EARLY GRANT OF ANNUAL OPTIONS. For a Non-Employee Director elected
as Director for the first time, the Committee may, in its discretion, grant the
Annual Option in a year prior to which the Annual Option is earned at the time
an Initial Option is granted, provided that any such Annual Option (the "Early
Annual Option") shall become vested according to the vesting schedule that would
have applied to the option had the option been granted on its regularly
scheduled grant date. The Committee may only grant Early Annual Options as far
as four years prior to the date on which the Annual Option would have been
granted had such option not been granted early.

5.       OPTION GRANT

         Each option granted under the Plan shall be a Non-Qualified Stock
Option and shall be evidenced by a Grant of Option duly executed on behalf of
the Corporation and shall comply with and be subject to the terms and conditions
of the Plan.

6.       OPTION EXERCISE PRICE

         The option exercise price for an option granted under the Plan shall be
the fair market value of the Shares covered by the option at the time the option
is granted. Fair market value shall be the mean between the high and low quoted
selling prices of the Common Stock on the date the option is granted as reported
on the Nasdaq National Market or, if not so quoted, on the principal national
securities exchange on which the Common Stock is then listed. The option
exercise price shall be subject to adjustment in accordance with Section 9
hereof.

7.       MANNER OF EXERCISE OF OPTIONS

         (a) TIME AND MANNER OF EXERCISE OF OPTIONS.

         Options granted under the Plan shall become exercisable in full on the
one year anniversary of the date of the grant, subject to the limitations
applicable to Early Annual Options set forth in Section 4(b). To the extent that
the right to exercise an option has accrued and is in effect, the option may be
exercised in full at one time or in part from time to time, by giving written
notice to the Corporation, signed by the person or persons exercising the
option, stating the number of Shares with respect to which the option is being
exercised, accompanied by payment in full for such Shares. Payment may be made
in whole or in part by (i) cash or cash equivalents, (ii) shares of Common Stock
of the Corporation already owned for a period of at least six months, or not
acquired directly or indirectly from the Corporation by the person exercising
the option, valued at fair market value as defined above on the business day
immediately prior to the date of exercise, (iii) delivery (on a form prescribed
by the Committee) of an irrevocable direction to a securities broker approved by
the Corporation to sell all or part of the shares of Common Stock being
purchased under the Plan and to deliver all or part of the sales proceeds to the
Corporation, or (iv) such other form of payment which the Committee determines
to be acceptable and consistent with applicable laws, regulations and rules.

         (b) TAXES.

         The optionee shall pay to the Corporation, or make provision
satisfactory to the Committee for payment of, any taxes required by law to be
withheld in respect of any option granted under the plan no later than the date
of the event creating the tax liability. In the Committee's discretion, the
minimum statutory withholding obligations, based on the minimum statutory
withholding rates for federal and state tax purposes, may be paid in whole or in
part in Shares of Common Stock retained from the exercise of the option, valued
at the fair market value of the Common Stock on the date of exercise.

         (c) TERM OF OPTIONS.

         The Expiration Date for each option shall be the earlier of (i) the
10th anniversary of the date of grant or, (ii) the date 12 months after the
termination of such Non-Employee Director's service as a director for any
reason.

8.       OPTIONS NOT TRANSFERABLE

         The right of an optionee to exercise an option granted to him or her
under the Plan and any interest therein or in the Shares received upon exercise
shall be assignable or transferable by such optionee in a respect other than by
will or the laws of descent and distribution only at the discretion of the
Board, and any such option shall be exercisable during the lifetime of such
optionee only by him or her except as expressly permitted by the Board. Any
option granted under the Plan shall become null and void and shall be without
further force or effect upon the bankruptcy of the optionee, or upon any
attempted assignment or transfer of such option or any interest therein (except
as provided in the preceding sentence), including, without limitation, any
purported assignment, whether voluntary or by operation of law, pledge,
hypothecation or other disposition, attachment,

                                      3

<PAGE>

trustee process or similar process, whether legal or equitable with respect to
such option or any interest therein.

9.       ADJUSTMENTS UPON CHANGES IN CAPITALIZATION

         In the event that the outstanding shares of the Common Stock of the
Corporation are changed into or exchanged for a different number or kind of
shares or other securities of the Corporation or of another corporation by
reason of any reorganization, merger, consolidation, recapitalization,
reclassification, stock split-up, combination of shares or dividends payable in
capital stock, appropriate adjustment shall be made in the number and kind of
Shares as to which outstanding options, or portions thereof then unexercised
shall be exercisable, to the end that the proportionate interest of the optionee
shall be maintained as before the occurrence of such event; such adjustment in
outstanding options shall be made without change in the total price applicable
to the unexercised portion of such options and with a corresponding adjustment
in the option price per Share.

10.      RESTRICTIONS ON ISSUANCE OF SHARES

         The Corporation may impose such conditions with respect to the exercise
of options, including conditions relating to applicable federal or state
securities laws, as it considers necessary or advisable.

11.      TERMINATION AND AMENDMENT OF PLAN

         Unless sooner terminated as herein provided, or extended with the
approval of the stockholders of the Corporation, the Plan shall terminate on
February 20, 2012, except as to options granted prior to that date. The Board
may at any time terminate the Plan or make such modifications or amendments
thereto as it deems advisable; provided, however, that except as provided in
Section 9 the Board may not, without the approval of the stockholders of the
Corporation, (i) increase materially the benefits accruing to participants
hereunder, (ii) increase the maximum aggregate number of shares for which
options may be granted under the Plan or the number of shares for which an
option may be granted to any optionee, (iii) modify the provisions of Section 4
regarding eligibility, (iv) extend the expiration date of the Plan, or (v)
modify the provisions of Section 6 regarding the exercise price. Termination or
any modification or amendment of the Plan shall not, without the consent of an
optionee, materially adversely affect his or her rights under an option
previously granted to him or her.

12.      SCOPE OF AMENDMENT AND RESTATEMENT

         This Plan is amended and restated as of April 24, 2002 and its terms
shall apply to options granted from and after such date. Prior Options shall
be governed by the terms and provisions of the Plan as in effect when such
options were granted.

                HELIX TECHNOLOGY CORPORATION DIRECTORS' DEFERRED
                                COMPENSATION PLAN

                                    ARTICLE I

                                     GENERAL

         1.1 ESTABLISHMENT OF PLAN. Helix Technology Corporation ("Helix")
hereby establishes the Helix Directors' Deferred Compensation Plan (the
"plan"), effective as of February 20, 2002, to allow each member of the Helix
Board of Directors who is not also an officer or employee of Helix to defer
receipt of all or a portion of the cash compensation payable to him or her as
a director of Helix until his or her termination of services as director or,
subject to requirements set forth in Section 3.1, such other date as may be
specified by him or her.

         1.2 NO RIGHT TO CORPORATE ASSETS. This plan is unfunded and Helix will
not be required to set aside, segregate or deposit any funds or assets of any
kind to meet its obligations hereunder. Nothing in this plan will give a
participant, a participant's beneficiary or any other person any equity or other
interest in the assets of Helix, or create a trust of any kind or a fiduciary
relationship of any kind between Helix and any such person. Any rights that a
participant, beneficiary or other person may have under this plan will be solely
those of a general unsecured creditor of Helix.

         1.3 LIMITATION ON RIGHTS CREATED BY PLAN. Nothing in this plan will
give a participant any right to continue as a director of Helix.

         1.4 NONALIENATION OF BENEFITS. The rights and benefits of a participant
in this plan are personal to the participant. No interest, right or claim under
this plan and no distribution therefrom will be assignable, transferable or
subject to sale, mortgage, pledge, hypothecation, anticipation, garnishment,
attachment, execution or levy, except by designation of beneficiaries as
provided in Section 3.5.

         1.5 BINDING EFFECT OF PLAN. This plan will be binding upon and inure to
the benefit of participants and designated beneficiaries and their heirs,
executors and administrators, and to the benefit of Helix and its assigns and
successors in interest.

         1.6 ADMINISTRATION. This plan will be administered by such person or
committee as the Chief Executive Officer of Helix shall designate (the
"Administrator").

         1.7 INTERPRETATION. This plan will be construed, enforced and
administered according to the laws of the State of Delaware.

                                   ARTICLE II

                            DEFERRAL OF COMPENSATION

         2.1 DEFERRAL AGREEMENT. Any member of the Board of Directors of Helix
who is not an officer or employee of Helix or its subsidiaries (an "outside
director") is eligible to participate in this plan. An outside director may
participate in the plan by executing an agreement before the first day of any
calendar quarter in which such agreement will take effect authorizing Helix to
defer all or a portion of his or her compensation as director (the "deferral
agreement"). A deferral agreement will remain in effect for each succeeding
calendar quarter unless the participant files a written revocation or
superseding deferral

<PAGE>

agreement with the Secretary of Helix. A deferral agreement for any particular
quarter is irrevocable after the last day of the immediately preceding calendar
quarter.

         2.2 AMOUNT OF DEFERRAL. Each participant may elect in his or her
deferral agreement to defer 25 percent, 50 percent, 75 percent or 100 percent of
the total cash compensation paid to the participant as an outside director of
Helix.

         2.3 DEFERRAL ACCOUNT. For bookkeeping purposes only, the Administrator
will establish and maintain an account (the "deferral account") for each
participant which documents the compensation deferred by the participant,
earnings credited to the account and payments from the account. The deferral
account will consist of a subaccount for amounts earning interest, which will be
denominated on a dollar basis (the "cash account"), and a subaccount for amounts
invested in hypothetical shares of Helix Common Stock, $1.00 par value ("Helix
Stock"), which will be denominated on a share basis (the "stock equivalent
account"). Each participant will indicate in his or her deferral agreement the
percentage of future deferrals to be invested in the cash account and the stock
equivalent account. Amounts may not be transferred between the cash account and
the stock equivalent account except pursuant to Section 3.2.

         2.4 CASH ACCOUNT. As of the first day of each calendar quarter, the
Administrator will credit to the participant's cash account an amount equal to
the amount of compensation otherwise payable to the participant in the preceding
calendar quarter which the participant has elected to defer and invest in the
cash account. As of the last day of each calendar quarter, the Administrator
will credit interest on the balance in the cash account on that date at the
prorata rate payable on 10-year Treasury notes hypothetically purchased on the
first day of such calendar quarter. For a participant receiving installment
payments, interest will be credited on the balance from time to time remaining
in the cash account until the account has been completely paid.

         2.5 STOCK EQUIVALENT ACCOUNT. As of the first day of each calendar
quarter, the Administrator will credit to the participant's stock equivalent
account a number of shares of Helix Stock equal to the amount of compensation
otherwise payable to the participant in the preceding calendar quarter which the
participant has elected to defer and invest in such Helix Stock divided by the
applicable stock price for such Helix Stock. The applicable stock price for such
Helix Stock shall mean the closing price of Helix Stock on the last trading day
during the applicable calendar quarter as reported by the Nasdaq National
Market. As of the date of payment of any cash dividend on Helix Stock, the
Administrator will credit to the stock equivalent account a number of shares of
Helix Stock upon which such dividend was declared equal to (i) the cash dividend
per share times the number of shares Helix Stock credited to the stock
equivalent account as of the dividend record date divided by (ii) the closing
price for such Helix Stock on the date of payment of the dividend. As of the
date of payment of any stock dividend on Helix Stock, the Administrator will
credit to the stock equivalent account a number of shares equal to the stock
dividend declared times the number of shares of Helix Stock credited to the
stock equivalent account as of the dividend record date. In the event of any
stock dividend, recapitalization, reorganization, merger, consolidation,
split-up, spin-off, exchange of shares or similar change affecting the Helix
Stock, appropriate adjustment will be made in the number and/or kind of shares
or other securities credited to the stock equivalent account. The stock
equivalent account is maintained for bookkeeping purposes only, and shares
credited to the stock equivalent account are not considered actual shares of
Helix Stock for any purpose and a participant will have no rights as a
stockholder with respect to such shares. Shares will include fractional shares
computed to three decimal places.

<PAGE>

                                   ARTICLE III

                        PAYMENT OF DEFERRED COMPENSATION

         3.1 COMMENCEMENT OF PAYMENT. Each participant will elect in his or her
deferral agreement to have payments commence in any calendar year as may be
specified; provided, however, that the earliest calendar year that a participant
may elect to have payments commence shall be the second calendar year following
the date of such election. For example, a deferral agreement executed in 2002
may not specify a payment commencement date earlier than 2004. Such election
will be irrevocable. Notwithstanding the foregoing, payments shall commence
earlier as described in Sections 3.3 and 3.4 below upon a participant's
termination of services as director.

         3.2 ELECTION OF FORM OF PAYMENT. Each participant will elect in his or
her deferral agreement to have his or her cash account paid in either a lump sum
or in annual installments for a period specified by the participant, which
period may not exceed five years. Each participant will elect in his or her
deferral agreement to have his or her stock equivalent account paid in a lump
sum or transferred to his or cash account if installment payments described in
Section 3.4 apply on the date a lump sum would be paid in an amount equal to the
number of shares of Helix Stock in his or her stock equivalent account times the
closing price for such Helix Stock as of the trading day preceding the date of
transfer.

         3.3 LUMP SUM PAYMENTS. A participant who elects to have his or her
deferral account paid in a lump sum will receive the lump sum payment on or
before March 1 of the year specified in the deferral agreement for commencement
of payment or, if the distribution event is due to his or her termination of
services as director, within ten (10) days following such termination of
services. The lump sum payment will consist of cash in the amount credited to
his or her cash account plus an amount equal to the number of shares of Helix
Stock in his or her stock equivalent account times the closing price for such
Helix Stock as of the trading day preceding the date of payment.

         3.4 INSTALLMENT PAYMENTS. A participant who elects to have his or her
deferral account paid in annual installments will receive an installment payment
on or before March 1 of each year that installments are due commencing with the
year specified in his or her deferral agreement or, if the distribution event is
due to his or her termination of services as director, on a date within 10 days
following such termination of services. Each installment payment will consist of
cash in the amount credited to his or her cash account, including any amounts
transferred from his or her stock equivalent account, on the date of payment
divided by the number of annual installments remaining to be paid.

         3.5 BENEFICIARIES. A participant may designate in his or her deferral
agreement a beneficiary or beneficiaries (which may be an entity other than a
natural person) to receive any payments to be made upon his or her death. A
participant may elect to have payments to beneficiaries paid in a lump sum or in
annual installments for a period not to exceed five years. At any time, and from
time to time, a participant may change or revoke his or her designation of
beneficiary or form of payment without the consent of any beneficiary. Any such
designation, change or revocation must be made in writing and filed with the
Secretary. If the participant designates more than one beneficiary, any payments
to beneficiaries will be made in equal percentages unless the participant
designates otherwise. Any portion of a participant's deferral account that is
not disposed of by designation of beneficiary upon the participant's death will
be paid to his or her estate.

         3.6 PAYMENTS ON DEATH. If a participant dies before full payment of his
or her deferral account, Helix will make payments to the participant's
designated beneficiary or beneficiaries, or to his or

                                       3
<PAGE>

her estate, as applicable, of the amount remaining in the deceased participant's
deferral account. Such payments will be in the form designated by the
participant and will commence on the first day of the calendar quarter following
the death of the participant (or as soon thereafter as practicable) and, in the
case of annual installments, will be paid on or before March 1 of each
succeeding year.

         3.7 HARDSHIP DISTRIBUTIONS FROM ACCOUNTS. The Administrator may, in its
discretion, distribute a portion or all of a participant's cash account in case
of an unforeseeable emergency. For purposes of this Section 3.7, an
unforeseeable emergency shall mean severe financial hardship to a participant
that arises from a sudden and unexpected illness or accident of the participant
or of a dependent of a participant, loss of the participant's property due to
casualty, or similar extraordinary and unforeseeable circumstances arising as a
result of events beyond the control of such participant. The Administrator will
determine the date of payment of the distribution. Hardship distributions are
not permitted from a participant's stock equivalent account.

                                   ARTICLE IV

                            AMENDMENT AND TERMINATION

         4.1 AMENDMENT. Helix may, without the consent of any participant,
beneficiary or other person, amend the plan at any time and from time to time;
provided, however, that no amendment will reduce the amount credited to the
deferral account of any participant.

         4.2 TERMINATION. Helix may terminate the plan at any time. Upon
termination of the plan, payments from a participant's deferral account shall be
made in the manner and at the time prescribed in Article III; provided, however,
that Helix may, in its discretion, distribute a participant's deferral account
in a lump sum as soon as practicable after the date the plan is terminated.

         Adopted by the Board of Directors on February 20, 2002.
