                           CHANGE IN CONTROL AGREEMENT
                           ---------------------------

This Change In Control Agreement ("Agreement") is dated as of October 6th 1997,
and is entered into by and between HENRY MASON ("Executive") and Haskel Energy
Systems Limited (CRN 1278832 whose registered office is at North Hylton Road,
Sunderland, SR5 3JD, England.


RECITALS
- --------

Haskel considers it to be in the best interest of Haskel, Haskel International
Inc. ("HII") and HII's shareholders that the Executive be encouraged to continue
his employment with Haskel and continue to devote full attention to Haskel's
business notwithstanding the possibility, threat or occurrence of an
acquisition, merger, or change of control involving HII. Haskel also believes
that it is in the best interest of Haskel, HII and its shareholders to minimise
potential conflicts of interest and to diminish inevitable distractions arising
from the possibility of an acquisition, merger or change of control.


Accordingly, in order to secure these benefits for Haskel, and to induce the
Executive to remain in the employ of Haskel, and for other good and valuable
consideration, the Board of Directors of Haskel has caused Haskel to enter into
this Agreement.

                a majority thereof, unless the election, or the nomination for
                election by HII's shareholders, of each new Board member was
                approved by a vote of at least three quarters of the Board

                "Subsidiary" shall mean any corporation or other entity of which
                more than 50% of the outstanding voting stock or voting power is
                beneficially owned directly or indirectly by HII. If the
                approval of the shareholders of HII for any of the occurrences
                set forth in sub Clauses (a) to (d) above is obtained prior to
                such occurrence, then such shareholder approval shall constitute
                the Event.


4.      EFFECTIVE PERIOD

For the purpose of this Agreement, the "Effective Date" is the period commencing
on the Event Date and ending on the earlier of the Expiration Date or the third

5.      TERMINATION OF EMPLOYMENT
        -------------------------


        (a)     General. The Executive shall be entitled to the payments and
                benefits described in Clause 6 (a) of this Agreement in the
                event the Executive's employment is terminated (i) by Haskel
                during the Effective Period for any reason, other than as a
                result of Executive's death or for Disability or Cause in
                accordance with the terms of this Clause 5, or (ii) by the
                Executive for Good Reason pursuant to a Notice of Termination
                delivered during the Effective Period.

                (i)     Death. The Executive's employment shall terminate
                        automatically upon his death.



   3



                (ii)    Disability. If the Disability of the Executive occurs
                        during the Effective Period (pursuant to the definition
                        of Disability set forth below), Haskel may give
                        Executive written notice in accordance with Clause 15 of
                        this Agreement of its intention to terminate the
                        Executive's employment. In such event, the Executive's
                        employment with Haskel shall terminate effective on the
                        30th day after receipt of such notice by the Executive
                        (the "Disability Effective Date"), provided that, within
                        the 30 days after such receipt, the Executive shall not
                        have returned to full-time performance of the
                        Executive's duties. For the purposes of this Agreement,
                        "Disability" shall mean the absence of the Executive
                        from his duties with Haskel on a full-time basis for 180
                        consecutive business days or such shorter period as a
                        result of incapacity due to mental or physical illness
                        which is both (i) determined to be total and permanent
                        by a physician selected by Haskel or its insurers and
                        acceptable to the Executive or his legal representative,
                        and (ii) entitles the Executive to the payment of
                        long-term disability benefits from Haskel's long-term
                        disability plan commencing immediately upon the
                        Disability Effective Date.

                (iii)   Cause. Haskel may terminate the Executive's employment
                        during the Effective Period for Cause. For the purposes
                        of this Agreement, "Cause" shall be limited to:

                        (a)     The conviction of the Executive for commission
                                of an indictable offence, or

                        (b)     The wilful engaging by Executive in gross
                                misconduct which materially and demonstrably
                                injures Haskel. For the purposes of this sub
                                Clause, no act or failure to act on the part of
                                the Executive shall be considered "wilful"
                                unless done, or omitted to be done, by the
                                Executive not in good faith and without
                                reasonable belief that his action or omission
                                was in the best interest of Haskel.

                        (c)     The issuance of an order, judgment or decree of
                                any court of competent jurisdiction permanently
                                enjoining the Executive from violating any
                                provision of the U.S. legislation known as the
                                Securities Act 1933, the Securities Exchange Act
                                1934 and applicable securities law of a state.

                        (d)     A final judgment of a court holding Executive
                                liable in a civil action based upon conduct
                                showing that Execution breached a fiduciary duty
                                to Haskel.

                (iv)    Good Reason. The Executive's employment may be
                        terminated by the Executive for Good Reason. For
                        purposes of this Agreement, "Good Reason" shall mean:

                        (a)     The assignment to the Executive of any duties
                                inconsistent in any material respect with his
                                position (including status, offices, titles and
                                reporting requirements), authority, duties or
                                responsibilities as in effect on the Event Date,
                                or any other action by Haskel which results in a
                                diminution in such position, authority, duties
                                or responsibilities, excluding for this purpose
                                an isolated, insubstantial and inadvertent
                                action not taken in bad faith and






   4



                                which is remedied by Haskel promptly after
                                receipt of notice thereof given by the
                                Executive;

                        (b)     Any failure by Haskel to reappoint the Executive
                                to a position held by him on the Event date,
                                except as result of the termination of
                                Executive's employment by Haskel for Cause or
                                Disability, the death of the Executive, or the
                                termination of the Executive's employment by the
                                Executive other than for Good Reason;

                        (c)     Reduction by Haskel in the Executive's basic
                                salary as in effect on the date hereof or as the
                                same may be increased from time-to-time;

                        (d)     The taking of any action by Haskel (including
                                the elimination of medical and life insurance
                                plans without providing substitutes therefore or
                                the reduction of the Executive's benefits
                                thereunder) that would substantially diminish
                                the aggregate value of the Executive's bonus
                                awards and other fringe benefits including
                                executive benefits and perquisites from the
                                levels in effect prior to the Event Date;

                        (e)     Haskel requiring the Executive to be based at
                                any office or location which increases the
                                distance from his home to the office or location
                                by more than 35 miles above the number of miles
                                the Executive drives to the office as of the
                                Event Date;

                        (f)     Any purported termination by Haskel of the
                                Executive's employment otherwise than pursuant
                                to a Notice of Termination; or

                        (g)     Any failure by Haskel to comply with and satisfy
                                Clause 10 (c) of this Agreement.

                For purposes of this Clause, any good faith determination of
                "Good Reason" made by Executive shall be conclusive.

                (b)     Notice of Termination. Any termination of the
                        Executive's employment by Haskel during the Effective
                        Period for any reason, or by the Executive for Good
                        Reason, shall be communicated by Notice of Termination
                        to the other party hereto given in accordance with
                        Clause 15 of this Agreement. For the purposes of this
                        Agreement, a "Notice of Termination" means a written
                        notice which (i) indicates the specific termination
                        provision in this Agreement relied upon, (ii) to the
                        extent applicable, sets forth in reasonable detail the
                        facts and circumstances claimed to provide a basis for
                        termination of the Executive's employment under the
                        provision so indicated and (iii) if the Date of
                        Termination (as defined below) is other than the date of
                        receipt of such notice, specifies the terminate date
                        (which date shall not be more than thirty days after the
                        giving of such notice). The facts and circumstances set
                        forth in any Notice of Termination given by Haskel
                        pursuant to a purported termination of the Executive for
                        Cause shall constitute the exclusive set of facts and
                        circumstances upon which Haskel may rely to attempt to
                        demonstrate that Cause for such termination existed. The
                        failure by the






   5


                        Executive to set forth in the Notice of Termination any
                        fact or circumstance which contributes to a showing of
                        Good Reason shall not waive any right of the Executive
                        hereunder or preclude him from asserting such fact or
                        circumstance in enforcing his rights hereunder.

                (c)     Date of Termination. "Date of termination" means (i) if
                        the Executive's employment is terminated by Haskel for
                        Cause, or by the Executive for Good Reason, the date of
                        receipt of the Notice of Termination or a later date
                        (within the limit set forth in subsection (b)) specified
                        therein, as the case may be, (ii) if the Executive's
                        employment is terminated by Haskel other than for Cause
                        or Disability, the Date of Termination shall be the date
                        on which Haskel notifies Executive of such termination
                        and (iii) if the Executive's employment is terminated by
                        reason of death or Disability, the Date of Termination
                        shall be the date of death of the Executive or the
                        Disability Effective Date, as the case may be.

6.      OBLIGATIONS OF HASKEL UPON TERMINATION
        --------------------------------------

(a)     Good Reason, Other Than for Cause, Death or Disability.
        -------------------------------------------------------

        If Haskel shall terminate the Executive's employment other than for
        Cause or Disability during the Effective Period, or the Executive shall
        terminate employment for Good Reason pursuant to a Notice of Termination
        delivered during the Effective Period, Haskel agrees to make the
        payments and provide the benefits described below. Haskel shall not be
        obligated to make such payments and provide such benefits if the
        Executive's employment with Haskel terminates as a result of his death.

        (i)     Haskel shall pay to the Executive in a lump sum in cash within
                10 days after the Date of Termination an amount equal to the
                product of (1) and (2), where (1) is "2" and (2) is the sum of
                (x) the Executive's highest rate of annual basic salary in
                effect at any time in the two years preceding the Date of
                Termination and (y) the highest annual amount of any bonus paid
                in respect of the most recent three fiscal years ending before
                the Date of termination; provided, however, that if any bonus
                otherwise payable under Haskel's bonus scheme in respect of the
                fiscal year preceding the fiscal year in which the Date of
                termination occurs has not been paid in full on or before the
                Date of Termination, in this clause (y) shall be replaced by "[
                ]". (The amount in this Clause (y) is referred to hereinafter as
                the "Incentive Compensation Payment.")

        (ii)    (A) Haskel shall pay Executive his or full basic salary through
                the Date of Termination at the rate in effect at the time the
                Notice of Termination is given plus a pro-rata share of the
                Incentive Compensation Payment. Such pro-rata share shall equal
                the fraction of Haskel's fiscal year which preceded the Date of
                Termination. (B) In addition, if the bonus otherwise payable
                under Haskel's bonus scheme in respect of the fiscal year,
                preceding the fiscal year in which the Date of Termination
                occurs has not been paid in full on or before the Date of
                Termination, Haskel shall pay the Executive an amount equal to
                the difference between the Incentive Compensation Payment and
                the portion (if any) which was actually paid to the Executive of
                such bonus in respect of the fiscal year preceding the fiscal
                year in which the Date of Termination occurs.

        (iii)   For two years after the Executive's Date of Termination, Haskel
                shall continue to provide medical and life insurance benefits
                and fringe benefits and other



   6



                perquisites to the Executive and his family at least equal to
                those which would have been provided to them if the Executive's
                employment had not been terminated in accordance with the most
                favourable plans, practices, programs or policies of Haskel and
                its affiliated companies applicable generally to other peer
                executives and their families immediately preceding the Date of
                Termination; provided, however, that if the Executive becomes
                re-employed with another employer, the medical, life insurance
                and other benefits described herein shall cease and terminate
                thirty (30) days after the effective date of the Executive's
                reemployment. In connection with the foregoing, the Executive
                agrees to notify Haskel in writing of his employment within Ten
                days (10) of such reemployment. For purposes of determining
                eligibility (but not the time of commencement of benefits) of
                the Executive for retirement benefits pursuant to such plans,
                practices, programs and policies, Executive shall be considered
                to have remained employed until three years after the Date of
                Termination and to have retired on the last day of such period.
                In the event that the Executive's participation in any of the
                plans, programs, practices or policies of Haskel referred to in
                this subsection is barred by the terms of such plans, programs,
                practices or policies, Haskel shall provide the Executive with
                benefits substantially similar to those which the Executive
                would be entitled as a participant in such plans, programs,
                practices or policies. At the end of the period of coverage, the
                Executive shall have the option to have assigned to him, at no
                cost and with no apportionment of prepaid premiums, any
                assignable insurance policy owned by Haskel and relating
                specifically to the Executive.

        (iv)    Haskel shall enable the Executive to purchaser the car, if any,
                that Haskel was providing for him at the time notice of
                Termination was given at the market value of such car at such
                time, as shown in the current addition of Glass Guide. The
                obligations set forth in this Section 6(a) (iv) are hereinafter
                referred to as the "Special Conditions".

        (v)     Any bonus previously deferred by the Executive (together with
                any accrued earnings or interest thereon) and any accrued
                vacation pay, in each case to the extent not theretofore paid
                (the amount referred to in this clause (v) and clause (ii) above
                being referred to as "Accrued Obligations").

        (vi)    To the extent not theretofore paid or provided, Haskel shall
                promptly pay or provide the Executive any other amounts or
                benefits required to be paid or provided or which the Executive
                is eligible to receive under any plan, program, policy,
                practice, contract or agreement of Haskel and its affiliated
                companies, including but not limited to any benefits payable to
                the Executive under a plan, policy, practice, etc., referred to
                in Section 7 below, (such other amounts and benefits being
                hereinafter referred to as "Other Benefits") in accordance with
                the terms of such plan, program, policy, practice, contract or
                agreement.

        (vii)   Upon a Change of Control, any and all options, warrants and
                grants to purchase Class A Common Stock of HII shall become
                immediately vested and exercisable by Executive.

(b)     Death. If the Executive's employment is terminated by reason of the
        Executive's death during the Effective Period, this Agreement shall
        terminate without further obligations to the Executive's legal
        representatives under this Agreement, other than for timely performance
        of the Special Obligations, payment of Accrued Obligations and payment
        or provision of the Other Benefits. Accrued Obligations shall be paid to
        the Executive's



   7

        estate or beneficiary, as applicable, in a lump sum in cash within 10
        days of the Date of Termination.

(c)     Disability. If the Executive's employment is terminated by reason of the
        Executive's Disability during the Effective Period, this Agreement shall
        terminate without further obligations to the Executive, other than for
        timely performance of the Special Obligations, payment of Accrued
        Obligations and payment or provision of Other Benefits. Accrued
        Obligations shall be paid to the Executive in a lump sum in cash within
        30 days of the Date of Termination.

(d)     Cause. If the Executive's employment shall be terminated for Cause
        during the Effective Period, this Agreement shall terminate without
        further obligations to the Executive (other than the obligation to pay
        to the Executive his basic salary earned through the Date of Termination
        and payment or provision of other Benefits).

(e)     The provisions of this Paragraph 6 supersede and replace any other
        agreement between Haskel and the Executive relating to the payment of
        any benefits as a result of the Termination of his employment by Haskel
        or the Executive's voluntary termination for any reason.

(f)     Other than for Good Reason

        (i)     If the Executive shall voluntarily terminate his employment,
                excluding a termination for Good Reason, within the six month
                period following the Event Date, this Agreement shall terminate
                without further obligations to Executive, except that Haskel
                shall pay to the Executive his basic salary earned through the
                Date of Termination and pay or provide the Other Benefits.

        (ii)    If the Executive shall voluntarily terminate his employment,
                excluding a termination for Good Reason, within the Effective
                Period, but after the six month period following the Event Date,
                this Agreement shall terminate without further obligations to
                Executive, except that Haskel shall (i) pay to the Executive his
                basic salary earned through the Date of Termination and pay or
                provide the Other Benefits, and (ii) timely perform the Special
                Obligations.

7.      Non-Exclusivity of Rights.
        --------------------------

Nothing in this Agreement shall prevent or limit the Executive's continuing or
future participation in any plan, program, policy or practice provided by Haskel
or any of its affiliated companies and for which the Executive may qualify, nor,
subject to Clause 19, shall anything herein limit or otherwise affect such
rights as the Executive may have under any contract or agreement with Haskel or
any of its affiliated companies. Amounts which are vested benefits or which
Executive is otherwise entitled to receive under any plan, policy, practice or
program of or any contract or agreement with Haskel or any of its affiliated
companies at or subsequent to the Date of Termination shall be payable in
accordance with such plan, policy, practice or program or contract or agreement
except as explicitly modified by this Agreement.

8.      Full Settlement
        ---------------

Haskel's obligation to make the payments provided for in this Agreement and
otherwise to perform its obligations hereunder shall not be affected by any
set-off, counterclaim, recoupment, defence to other claims, right or action
which Haskel may have against the Executive or others.






   8



In no event shall the Executive be obligated to seek other employment or take
any other action by way of mitigation of the amounts payable to him under any
one or more provisions of this Agreement and, except as provided in Clause
6(a)(iii), such amounts shall not be reduced whether or not Executive obtains
other employment. Haskel agrees to pay, to the full extent permitted by law, all
legal fees and expenses which the Executive may reasonably incur as a result of
any contest (regardless of the outcome thereof) by Haskel, the Executive or
others of the validity or enforceability of, or liability under, any provision
of this Agreement or any guarantee of performance thereof (including as a result
of any contest by the Executive about the amount of any payment pursuant to this
Agreement), plus in each case interest on any delayed payment at the applicable
Judgment Rate, the Executive shall be entitled to payment of such legal fees and
expenses on a monthly basis during the pendency of any contest. Accordingly,
Haskel shall, on the tenth business day of each month following the Executive's
Date of Termination, pay the Executive any legal fees and expenses incurred by
him as a result of a dispute hereunder for which the Executive presented
invoices to Haskel on or before the last business day of the preceding month.
Notwithstanding the foregoing, Haskel shall be entitled to reimbursement by the
Executive (1) for any legal fees or expenses of Executive in any contest by
Executive about the amount of any payment under this Agreement if it is
determined that Haskel did not breach this Agreement and Executive's claim was
not made in good faith, and (2) to the extent it is determined that the amount
of such legal fees and expenses was not reasonable.

9.      Certain Additional Payments by Haskel
        -------------------------------------

(a)     In the event that any payment or distribution by Haskel to or for the
        benefit of Executive (whether paid or payable or distributed or
        distributable pursuant to the terms of this Agreement or otherwise, but
        determined without regard to any additional payments required under this
        Clause 9 (a)) ("Payments") is determined to be subject to (1) the tax
        imposed by or any taxation authority (2) any interest or penalties are
        incurred by the Executive with respect to such tax, then Haskel shall
        pay to Executive an additional payment (a "Gross-Up Payment") in an
        amount such that after payment by Executive of all taxes (including any
        interest or penalties imposed with respect to such taxes), including,
        without limitation, any income taxes (and any interest and penalties
        imposed with respect thereto) imposed upon the Gross-Up Payment,
        Executive retains an amount of the Gross-Up Payment equal to the Tax
        imposed upon the Payments.

(b)     Subject to the provisions of Clause 9 (c), all determinations required
        to be made under this Clause 9, including whether and when a Gross-Up
        Payment is required and amount of such Gross-Up Payment and the
        assumptions to be utilised in arriving at such determination, shall be
        made by such firm of chartered accountants as may be designated by the
        Executive and which is reasonably satisfactory to Haskel (the
        "Accounting Firm"), which shall provide detailed supporting calculations
        both to Haskel and Executive within 15 business days of the receipt of
        request from Executive to Haskel. All fees and expenses of the
        Accounting Firm shall be borne solely by Haskel. Any Gross-Up Payment,
        as determined pursuant to this Clause 9 (b), shall be paid by Haskel to
        Executive within five days of the receipt of the Accounting Firm's
        determination.

(c)     The Executive shall notify Haskel in writing of any written claim
        actually received by the Executive from the relevant taxation authority
        requesting the payment by the Executive of any tax in respect of
        Payments. Such notification shall be given as soon as practicable (which
        shall be deemed to have occurred if it is given within 20 business days)
        after the Executive actually receives such claim and shall apprise
        Haskel of the nature of such claim, and the date on which such claim is
        requested to be paid. The Executive shall not pay such claim prior to
        the expiration of the 30 day period following the date on which it





   9


        gives such notice to Haskel (or such shorter period ending on the date
        that any payment of taxes with respect to such claim is due). If Haskel
        notifies the Executive in writing prior to the expiration of such period
        that it desires to contest such claim, the Executive shall:

        (i)     Give Haskel any information reasonably requested by Haskel
                relating to such claim;

        (ii)    Take such action in connection with contesting such claim as
                Haskel shall reasonably request in writing from time to time,
                including, without limitation, accepting legal representation
                with respect to such claim by a legal adviser reasonably
                selected by Haskel;

        (iii)   Co-operate with Haskel in good faith in order to context such
                claim effectively, and

        (iv)    Permit Haskel to participate in any proceedings relating to such
                claim;

        provided, however that Haskel shall bear and pay directly all costs and
        expenses (including additional interest and penalties) incurred in
        connection with such contest and shall indemnify and hold the Executive
        harmless, on an after tax basis, for any tax (including interest and
        penalties with respect thereto) imposed as a result of such
        representation and payment of costs and expenses. Without limitation on
        the foregoing provisions of this Clause 9 (c), Haskel shall control all
        proceedings taken in connection with such contest and, at its sole
        option, may pursue or forego any and all administrative appeals,
        proceedings, hearings and conferences with the taxing authority in
        respect of such claim and may, at its sole option, either direct the
        Executive to pay the tax claimed and sue for a refund or contest the
        claim in any permissible manner, and the Executive agrees to prosecute
        such contest to a determination before any administrative tribunal, in a
        court of initial jurisdiction and in one or more appellate courts, as
        Haskel shall determine; provided, however, that if Haskel directs the
        Executive to pay such claim and sue for a refund, Haskel shall advance
        the amount of such payment to the Executive on an interest free basis
        and shall indemnify and hold the Executive harmless, on an after tax
        basis, from any tax (including interest or penalties with respect
        thereto) imposed with respect to such advance or with respect to any
        imputed income with respect to such advance; and further provided that
        any extension of the statute of limitations relating to payment of taxes
        for the taxable year of Executive with respect to which such contested
        amount is claimed to be due is limited solely to such contested amount.
        Furthermore, Haskel's control of the contest shall be limited to issues
        with respect to which Gross Up Payment would be payable hereunder and
        the Executive shall be entitled to settle or contest, as the case may
        be, any other issue raised by the Inland Revenue or any other taxing
        authority.

(d)     If, after the receipt of the Executive of an amount advanced by Haskel
        pursuant to Clause 9 (c), the Executive becomes entitled to receive any
        refund with respect to such claim, the Executive shall (subject to
        Haskel's complying with the requirements of Clause 9 (c)) promptly pay
        to Haskel the amount of such refund (together with any interest paid or
        credited therein after taxes applicable thereto). If, after the receipt
        by the Executive of an amount advanced by Haskel pursuant to Clause 9
        (c) determination is made that the Executive shall not be entitled to
        any refund with respect to such claim and Haskel does not notify the
        Executive in writing or its intent to contest such denial of refund
        prior to the expiration of 30 days after such determination, then such
        advance shall be forgiven



   10



        and shall not be required to be repaid and the amount of such advance
        shall offset, to the extent thereof, the amount of Gross Up Payment
        required to be paid.

10.     Successors
        ----------

(a)     This Agreement is personal to the Executive and without the prior
        written consent of Haskel shall not be assignable by the Executive
        otherwise than by will or the laws of descent and distribution. This
        Agreement shall inure to the benefit of and be enforceable by the
        Executive's legal representatives.

(b)     This Agreement shall inure to the benefit of and be binding upon Haskel
        and its successors and assigns.

(c)     Haskel will require any successor (whether direct or indirect, by
        purchase, merger, consolidation or otherwise) to all or substantially
        all of the business and/or assets of Haskel to assume expressly and
        agree to perform this Agreement in the same manner and to the same
        extent that Haskel would be required to perform it if no such succession
        had taken place. As used in this Agreement, "Haskel" shall mean Haskel
        as hereinbefore defined and any successor it its business and/or assets
        as aforesaid which assumes and agrees to perform this Agreement by
        operation of law, or otherwise.

11.     Arbitration
        -----------

(a)     Because it is agreed that time will be of the essence in determining
        whether any payments are due to the Executive under this Agreement, he
        may, if he desires, submit any claim for payment under this Agreement or
        dispute regarding the interpretation of this Agreement to arbitration in
        accordance with the Arbitration Acts. This right to select arbitration
        shall be solely that of the Executive, and he may decide whether or not
        to arbitrate in his discretion. The "right to select arbitration" is not
        mandatory on the Executive, and he may choose in lieu thereof to bring
        an action in an appropriate civil court. Once an arbitration is
        commenced, however, it may not be discontinued without the mutual
        consent of both parties to the arbitration. During the lifetime of the
        Executive only he can use the arbitration procedure set forth in this
        Clause.

(b)     In the event the arbitrator finds that Haskel has breached this
        Agreement, Haskel shall immediately take the necessary steps to remedy
        the breach. The award of the arbitrator shall be final and binding upon
        the parties. The award may be enforced in any appropriate court as soon
        as possible after its rendition. If an action is brought to confirm the
        award, both Haskel and Executive agree that no appeal shall be taken by
        either party from any decision rendered in such action.

12.     Governing Law
        -------------

The laws of England shall govern the validity and interpretation of this
Agreement, with regard to conflicts of laws.

13.     Headings
        --------

The headings of this Agreement are not part of the provisions hereof and shall
have no force or effect.

14.     Amendment

or to such other address as either party shall have furnished to the other in
writing in accordance herewith. Notices and communications shall be effective
when actually received by the addressee. Neither the failure of the Executive to
give any notice required by this Agreement (including but not limited to the
notice specified in Clause 9 (c) hereof), nor defects or errors in any notice
given by the Executive, shall relieve Haskel of any corresponding obligation
under this Agreement unless, and only to the extent that, Haskel is actually and
materially prejudiced thereby.

16.     Severability
        ------------

The invalidity or unenforceability of any provision of this Agreement shall not
effect the validity or enforceability of any other provision of this Agreement.

17.     Withholding Taxes
        -----------------



   12



Haskel may withhold from any amounts payable under this Agreement such taxes as
shall be required to be withheld pursuant to any applicable law or regulation.





18.     No Waiver
        ---------

The Executive's or Haskel's failure to insist upon strict compliance with any
provision hereof or any other provision of this Agreement or the failure to
assert any right the Executive or Haskel may have hereunder, including, without
limitation, the right of Executive to terminate employment for Good Reason shall
not be deemed to be a waiver of such provision or right or any other provision
or right of this Agreement.

19.     Counterparts
        ------------

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

executed and delivered as of the day and year first written above.
