|INTERPRETATION |  | 
|-------------- |  |

|-- |  | ------------------




AFFILIATE means any company, partnership or other entity which directly or indirectly controls, is controlled by or is under common control of either Hickson or the Pensioner.


|
|

HICKSON PENSION SCHEME means the Hickson UK Group Pension Scheme and/or the Hickson UK Senior
Executives Pension Scheme and any scheme that has taken on the liability to provide Pensioner or Mrs. Markham with benefits in respect of Pensioners Hickson service.


|
|




|2. |  | NON COMPETE
|-- |  | -----------




| | 2.1 |  | Due to the commercial and sensitive nature of Pensioners past services to Hickson the Pensioner agrees that he will not, during the time he is receiving
payments under this Agreement, provide services to or carry out work for any third party which involves specific products, or specific chemical processes which the Pensioner has been involved with whilst employed by Hickson or any of its Affiliates
or providing Services to or carrying out work for Hickson or any of its Affiliates in the areas or fields of expertise previously provided. The obligations in this Section 2.1 are in addition to, and not in lieu of, any other obligations Pensioner
may have in this regard. Without prejudice to any other remedy that may be available to Hickson for a violation of this Section 2.1, the parties acknowledge that Hicksons obligation to make any payments under Section 3 below is conditional
upon Pensioners compliance with this Section 2.1.
| | --- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




|3. |  | SUPPLEMENTAL PENSION PAYMENTS
|-- |  | -----------------------------




| | 3.1 |  | Effective May 1, 2002 and for each calendar month thereafter until the earliest of (1) the end of the calendar month in which Pensioner reaches age 60, (2) the
date Pensioner is approved for benefits under any Hickson Pension Scheme, (3) the month in which Pensioner dies, and (4) the date on which the Pensioner begins to carry out any work or
| | --- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------






---




provide any services in breach of Section 2.1 above, Pensioner will be paid by
Hickson GBP 1,407.66 per month. Such payment shall be made on or before the 17 th of each month by cheque
and shall be increased periodically for inflation to the same extent and on the same basis as a pension then being received by a pensioner under the Hickson UK Group Pension Scheme (such payment plus such periodic increase(s) shall be the
Monthly Supplemental Payment).





| | 3.2 |  | Within thirty days of the date which is the earlier of (1) the end of the calendar month in which Pensioner reaches age 60 and (2) the date Pensioner is
approved for retirement benefits under any Hickson Pension Scheme, Hickson will begin to pay on a monthly basis an amount equal to the difference (if any) between the monthly aggregate pension payable to Pensioner under all Hickson Pension Schemes
and the Monthly Supplemental Payment as in effect immediately prior to the earlier of such dates (Final Supplemental Figure); provided and for so long as such Final Supplemental Figure is greater than such monthly pension. If, however,
the Final Supplemental Figure is less than the initial full months instalment of aggregate pension payable from the Hickson Pension Schemes, the Pensioner shall begin to pay to Hickson on a monthly basis an amount equal to the difference
between the Final Supplemental Figure and the monthly aggregate pension payable under the Hickson Pension Schemes. As the pension payment from the Hickson Pension Schemes is increased annually, the foregoing figures shall be recalculated using such
increased pension payment figure and the Final Supplemental Figure used in the calculation shall also be increased by the same overall percentage as is used from time to time to increase for inflation the pension payment to Pensioner from the
Hickson Pension Schemes. Payments made under this Section 3.2 shall be made on or before the 17thof each
month by cheque. The payments under this Section 3.2 shall be made up to and including the month in which Pensioner dies.
| | --- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




| | 3.3 |  | Beginning with the next calendar month following the death of Pensioner, if payments were being made to Pensioner under Section 3.1 or 3.2 above, such payments
shall be recomputed and reduced and shall be made to the surviving spouse of Pensioner to the same extent as if such payments were being made from the Hickson Pension Schemes as if Pensioner had taken an early retirement pension on 1 May 2002 and
subsequently died leaving a surviving spouse. Payments to his surviving spouse under this Section 3.3 shall continue until the earlier of (1) the month in which his surviving spouse dies and (2) the termination of the Hickson UK Senior Executives
Pension Scheme or the Hickson UK Group Pension Scheme. If Pensioner was making payments to Hickson under Section 3.2, Mrs. Markham agrees to make the same monthly payments to Hickson (as recalculated from time to time in accordance with Section 3.2
following the death of the Pensioner) to take account of increases to the pension in payment) for the rest of her life reduced by 50%.
| | --- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




| | 3.4 |  | Payments made to Pensioner and Pensioners surviving spouse under this Section 3 shall be reduced by applicable taxes and similar withholdings as required
by law or benefit plan.
| | --- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




| | 3.5 |  | If Pensioner applies for a transfer out of any Hickson Pension Scheme at any time, he must immediately pay Hickson by cheque an amount equal to the total of all
payments made by Hickson under Section 3.1 and 3.2, and Hicksons obligation to make any further payments under this agreement will cease.
| | --- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




| | 3.6 |  | At any time Hickson may terminate its obligations to make the payments under this Section 3 upon payment of a lump sum to Pensioner (or his surviving spouse as
the case may be) in an amount equal to the actuarially determined present value of the aggregate payments still to be made by Hickson under Section 3 (and after taking into account payments to be made under the Hickson Pension Schemes), with all
calculations being carried out by an actuary appointed by Hickson.
| | --- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---




| | 3.7 |  | All references to the pension payable to the Pensioner under the Hickson Pension Schemes in this Section 3 shall be interpreted as references to the pension the
Pensioner would have received from the Hickson Pension Schemes had he not exercised any options which were available to him under any Hickson Pension Scheme whereby the pension payable to him would be reduced (including, without limitation, any
surrender of pension to provide a Dependants pension) other than any option to commute pension for lump sum.
| | --- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




| | 3.8 |  | Nothing in this Pension Supplement Agreement will operate to prejudice Pensioners entitlements or accrued rights under any Hickson Pension Scheme. In
particular this Pension Supplement Agreement will not create any charge, lien or right of set off against such entitlements or accrued rights, nor operate as an assignment, commutation or surrender of such entitlements or accrued rights.

|-- |  | -----------

spouse shall fail (1) to apply at least annually and within 14 days of the written request of Hickson for early retirement benefits under the Hickson Pension Schemes or (2) to comply with Section 5.1 below.
| | --- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




|5. |  | CONFIDENTIALITY

| | 5.1 |  | Pensioner and any surviving wife (including Mrs. Markham) shall keep the contents and arrangements made in this Agreement secret and strictly confidential

| | 6.1 |  | Any notice required by this Agreement to be given by either party to the other shall be in writing and shall be served by sending the same by registered post or
recorded delivery to the last known address of the other party and any receipt issued by the postal authorities shall be conclusive evidence of the fact and date of posting of any such notice.

PROMISSORY NOTE





GBP 46,778


1 May 2002





FOR VALUE RECEIVED, John H. Markham, who resides at Rob Royd House, Hound Hill Lane, Worsbrough, Barnsley S706TU, United Kingdom (the
Borrower), hereby promises to pay on Maturity Date (as defined below) to the order of Arch Chemicals, Inc., a Virginia corporation (the Lender), at 501 Merritt 7, Norwalk, Connecticut, USA, in lawful money of the United
Kingdom and in immediately available funds, the principal sum of FORTY-SIX THOUSAND SEVEN HUNDRED SEVENTY-EIGHT BRITISH POUNDS STERLING (GBP 46,778.00), or, if less, the aggregate unpaid principal amount of the loan made hereunder by the Lender to
the Borrower, and to pay interest on the unpaid balance of said principal sum from time to time outstanding as set forth below from the Maturity Date or the date of an Event of Default (as defined below) until paid in full, in like money, at said
office, at the dates and the rates per annum as set forth below.





This Note has been executed and delivered
subject to the following term and conditions:





(1)Loan.    Borrower
acknowledges that the Lender has advanced Forty-Six Thousand Seven Hundred Seventy-Eight British Pounds Sterling (GBP 46,778.00) on the date hereof (the Loan) represented by this Note. Borrower expressly authorizes the Lender to endorse
on Schedule 1 hereto, an appropriate notation evidencing repayment on account of the principal thereof, and the amount of interest paid; and the Borrower agrees that the amount shown on said Schedule 1 from time to time shall constitute the
principal amount owing to the Lender pursuant this Note, absent manifest error. Failure to make any such notation shall not limit or otherwise affect the obligations of Borrower hereunder. In the event the amount shown on Schedule 1 conflicts with
the amount noted as due pursuant to the books and records of the Lender, the books and records of the Lender shall control the disposition of the conflict. If during the term of this Promissory Note the United Kingdom adopts the euro as its
currency, the Lender may determine the equivalent amount of euros which are repayable, being the equivalent to the sterling amount then outstanding.





(2)Repayment of Loans.    The Borrower or his personal representative, as the case may be, shall repay the aggregate unpaid principal amount of the Loan
outstanding at the earliest of (a) the thirty (30) day following the date the Borrower is approved for an early retirement pension under the Hickson UK Group Pension Scheme and/or the Hickson UK Senior Executive Pension Scheme, (including any
successor scheme of either such Schemes) (the Hickson Pension Scheme), (b) the thirty (30) day following the date the Borrower reaches age 60, (c) the thirty (30) day following the date the Borrower transfers his accrued rights from the
Hickson Pension Scheme; (d) the thirty (30) day following the date the Borrower otherwise receives benefits from the Hickson Pension Scheme on its winding up and (e) the date of receipt by Borrower of any lump sum cash payment in respect of pension
benefits from the Hickson Pension Scheme (the earliest of (a), (b), (c), (d) and (e) being the Maturity Date); provided that if Borrower timely applies for the maximum lump sum payment in commutation of pension benefits under the Hickson
Pension Scheme (and has not exercised any options available to him which might reduce the amount of that lump sum) and to the extent that lump sum payment is insufficient to pay the outstanding balance of this Note in full, the outstanding principal
amount of this Note shall be forgiven to the extent and only to the extent of such insufficiency.





(3)Interest Rate; Additional Charges.
