Foreword

The Cytec Surface Specialties Supplemental Pension Plan is a group insurance plan in addition to the regular Cytec Group Insurance Plan. It is intended to provide employees with a Belgian employment
agreement, who are subject to Belgian social security contributions and graded G20 and higher, with a comfortable standard of living when they retire.

In this handbook you will find the necessary information about this supplemental pension plan. Note that this new supplemental plan will be in force as from 1 March 2008 onwards and replaces any
existing AXA supplemental plans.

We are sure this supplemental plan will contribute to your satisfaction as an employee of
Cytec.

|How can I position employee benefits in my own financial plan? |  | We all know that only few financial instruments allow an employer to deliver income to its employees on a tax efficient basis. One of those vehicles is a supplemental group
insurance which defers current employment income, taxable at marginal income rates and subject to full employee and employer social security contributions, to retirement income which is taxable at much lower tax rates (currently 16.66%) and subject
to limited social taxes (currently between 3.55% and 5.55% depending on the amount).

|Who is a member?                   |  | All employees with a Belgian employment agreement (whether fixed term or open-ended), who are subject to Belgian social security contributions and graded G20 and higher,
automatically become members of this supplemental pension plan. Membership is immediate from the date of hire (if taking a job graded G20 and higher) or at the date of promotion to a job graded G20 and higher.

|                                   |  | You continue your participation in this supplemental plan as long as you work for Cytec and are graded G20 or higher. This plan is interrupted in case of suspension of the
employment agreement (for example: termination, career interruption, full-time time credit).

|                                   | 
|When does the group insurance end? |  | Membership to the group insurance will cease as soon as you stop working for Cytec and, more precisely, in the following cases:

|                                   |  | Membership to this pension plan will also cease in case of demotion to a grade below G20. Note that in this case, no new contributions will be paid into this plan but you will
remain entitled to the already accrued reserves which will continue to earn interest (currently 3.25% plus profit sharing interest) until one of the three above listed situations occurs.

|                                    |  | As soon as you become a member of this supplemental plan, you start accruing additional retirement benefits.

|How is the pension benefit defined? |  | The additional retirement benefit you will receive when you retire (normal retirement age is 65), depends on the invested contributions and the return granted by the
insurance company.

|                                    |  | The contributions are fixed as follows:

| |  | The ICP budget is determined by Cytecs Executive Leadership Team in accordance with Cytec Industries Incentive Compensation Plan and relates to the prior
year of performance.                                                                          
| | 
| |  | The contribution is calculated and paid once a year, on March 1 of every year. The payment to the insurance company occurs within 8 working days.                                                                                                         
| | 
| |  | The contribution can never be lower than 250. In case of an incomplete year, a proportionate minimum amount will be paid (based on the effective number of full
affiliation months).                                                                     
| | 
| |  | The contribution can on the other hand not exceed the authorised tax deductible level. Indeed the sum of your legal/state pension and your extra-legal pensions cannot
exceed 80% of your last normal gross salary and this for a full career of 40 years.
| | 
| |  | AXA grants a guaranteed/fixed interest (of currently 3.25%) as well as a profit sharing interest on these contributions.

charges (currently 8.86%) related to these contributions.

applicable as for your regular group insurance plan (i.e. the accrued amount will be reduced with 3.55% up to 5.55% as social security charge and the remaining amount will be taxed at currently 16.66% in case of early retirement or 10.09% if you
continue working up to age 65).

accrued.                                                              
|                                                               | As from the January 1, 2010 the retirement benefit will no
longer be payable before age 60.

retirement benefit. On January 1, 2008, those amounted to about 3.55% to 5.55% social security contribution (depending on the level of the capital to be paid) plus 16.66% taxes, increased with communal taxes.

|                        |  | Until end 2009 you still have a last option which consists in having the accrued amount deposited in your bank account ( = surrender). Be careful, this option does have negative
consequences as the taxes are high.

|                        |  | (*) If you have worked less than one year at Cytec, the accrued rights consist in the reserves accrued with the personal contributions. If you leave the company with at least one
year seniority in the plan, then the accrued rights consist in the reserves accrued with the personal contributions and the employer contributions.
