8.                                       Restrictive Covenants.  (a) During the “Restriction Period” (as defined below), Executive will not, anywhere the Company conducts business (i) directly or indirectly, engage or participate in, or render services to (whether as officer, director, agent, owner, operator, member, shareholder, manager, consultant, strategic partner, employee or otherwise) any business that is directly or indirectly engaged in or that is competitive with the business of Company or any of its affiliates (a “Competing Business”).  For purposes of the foregoing, Executive will not be in breach of this Section 8(a) by reason of his ownership, directly or indirectly, of two percent or less of a Competing Business’ voting capital stock if (i) such Competing Business is publicly traded and (ii) Executive does not, directly or indirectly, control the operation or management of such Competing Business.  For purposes of this Agreement, the “Restriction Period” shall mean the period commencing on the date hereof and ending at the completion of: (i) in the case of Executive’s voluntary resignation of employment with the Company without Good Reason whether before or after a Change of Control, a period of up to twelve (12) months after Executive’s termination of employment, as specified by the Company within thirty (30) days of Executive’s termination of employment, provided that the Company agrees to continue to pay, and continues to pay, Executive his base salary during the period so specified in accordance with the Company’s normal payroll practice; or (ii) in the case of the termination of Executive’s employment with the Company for any other reason whether before or after a Change of Control, the Severance Period;

(b)                                 During the Restriction Period, Executive agrees that he will not, directly or indirectly, (i) solicit for employment, recruit or hire, either as an employee, a consultant or an independent contractor, any person who is or was during the preceding twelve (12) months an employee of the Company or any of its affiliates, (ii) induce or attempt to induce any person who is or was during the preceding twelve (12) months an employee of the Company or any of its affiliates to terminate his or her employment with the Company or its affiliates, (iii) solicit, interfere with, divert or take away or attempt to interfere with, divert or take away, any transaction, agreement, business opportunity or business relationship in which the Company or any of its affiliates is or was during the preceding twelve (12) months involved, or (iv) otherwise engage or participate in any effort or act to induce any person to discontinue a relationship with the Company or any of its affiliates.

(c)                                  From and after the date of this Agreement, Executive shall maintain the confidentiality of, and shall not use for the benefit of himself or others, any Confidential Information (as hereinafter defined) regarding the business, operations, properties or personnel of the Company and its affiliates; provided, however, that this Section 8(c) shall not restrict any disclosure by Executive of any Confidential Information that is required by applicable law (but only such portion of the Confidential Information that he is legally required to disclose) and only if Executive shall give the Company notice and a reasonable opportunity to contest such disclosure or seek an appropriate protective order.  “Confidential Information” means, but is not limited to, information, not generally known, about the Company’s and its affiliates’ processes, formulas, devices, products, potential products, specifications, computer programs, contract negotiations, terms of agreements, materials sources, supplier contacts, business developments, customer lists, financial information, research, development, manufacturing, purchasing, accounting, engineering, marketing, merchandising, selling, trade relations and technical services.

10

(d)                                 With respect to any Inventions (as hereinafter defined) and any Works of Authorship (as hereinafter defined) made or conceived by Executive, either solely or jointly with others, (1) during Executive’s past, present or future employment by the Company or its affiliates or (2) within one year after termination of his employment if based on Confidential Information, Executive agrees:

(i)                                     To promptly and fully inform the Company in writing of such Inventions or Works of Authorship.

(ii)                                  To assign (and Executive does hereby irrevocably assign) to the Company all of Executive’s rights to such Works of Authorship or Inventions, and to Applications for Letters Patent and to Letters Patent granted upon such Inventions.

(iii)                               To acknowledge and deliver promptly to the Company (without charge to the Company but at the expense of the Company) such written instruments and to do such other acts as may be necessary in the opinion of the Company to obtain copyrights and maintain Letters Patent and to vest the entire right and title thereto in the Company.

“Inventions” means discoveries, improvements and ideas (whether patentable or not) relating to any activities of the Company or its affiliates.  “Works of Authorship” means any original work or authorship within the purview of the copyright laws of the United States, and it is intended that all Works of Authorship created in the course of Executive’s employment with the Company or its affiliates will be works made for hire within the meaning of such copyright laws.

Except as listed on Schedule A to this Agreement, Executive will not assert any rights under any Inventions or Works of Authorship that relate to any past, present or possible future business of the Company or its affiliates as having been made or acquired by Executive prior to being employed by the Company.

(e)                                  Executive acknowledges and agrees that the restrictions contained in this Section 8 are reasonable and necessary protection of the immediate interests of the Company, and any violation of these restrictions would cause substantial injury to the Company and that the Company would not have entered into this Agreement without receiving the protective covenants contained in this Section 8.  In the event of a breach or a threatened breach by Executive of these restrictions, the Company will be entitled to an injunction restraining Executive from such breach or threatened breach (without the necessity of proving the inadequacy as a remedy of money damages or the posting of bond); provided, however, that the right to injunctive relief will not be construed as prohibiting the Company from pursuing any other available remedies, whether at law or in equity, for such breach or threatened breach.

(f)                                    Immediately upon termination of the Executive’s employment, the Executive shall return to the Company all documents (including all copies), material, and property belonging to the Company and its affiliates, including, but not limited to, manuals, policies, financial records, legal documents, customer lists, prospective customer lists, training materials and marketing materials.

11

9.                                       Definitions.  As used in this Agreement, the following terms shall have the following meanings:

(a)                                  “Cause” means:

(i)                                     the Executive’s willful and continued failure to substantially perform his duties (other than any such failure resulting from incapacity due to physical or mental illness), after written notice from the Company requesting such substantial performance is delivered to Executive, which notice identifies in reasonable detail the manner in which the Company believes the Executive has not substantially performed his duties and provides a reasonable period in which to cure such failure, or

(ii)                                  any act of fraud, embezzlement or theft on the Executive’s part against the Company or its affiliates.

(b)                                 “Good Reason” means:

(i)                                     a reduction in Executive’s duties or responsibilities;

(ii)                                  a reduction in Executive’s compensation or Target Bonus opportunity or a material reduction in employment benefits;

(iii)                               a material breach by the Company of this Agreement; or

(iv)                              a change of the Company’s headquarters or of Executive’s principal place of employment of more than 35 miles;

provided, however, that such event will not constitute Good Reason unless Executive has provided the Company notice of the existence of a Good Reason condition no more than 90 days after its initial existence and the Company has failed to remedy the condition within 30 days after such notice.

(c)                                  “Change in Control” means the earliest date at which:

(i)                                     any Person (which term shall mean any individual, corporation, partnership, group, association or other “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended, other than the Company or any employee benefit plans sponsored by the Company) is or becomes the “beneficial owner” (as defined in Rule 13d-3 under such Act), directly or indirectly, of securities of the Company representing 30% or more of the combined voting power of the Company’s outstanding Voting Securities (which term shall mean securities which under ordinary circumstances are entitled to vote for the election of directors) other than through the purchase of Voting Securities directly from the Company through a private placement;

(ii)                                  individuals who constitute the Board on the date hereof (the “Incumbent Board”) cease for any reason to constitute at least a majority thereof, provided that any person becoming a director subsequent to the date hereof whose election, or nomination for election by the Company’s shareholders, was approved by a

12

vote of at least a majority of the directors comprising the Incumbent Board shall from and after such election be deemed to be a member of the Incumbent Board;

(iii)                               a merger or consolidation involving the Company or its stock or an acquisition by the Company, directly or indirectly or through one or more subsidiaries, of another entity or its stock or assets in exchange for the stock of the Company is consummated, unless, immediately following such transaction, 70% or more of the then outstanding Voting Securities of the surviving or resulting corporation or entity will be (or is) then beneficially owned, directly or indirectly, by the individuals and entities who were the beneficial owners of the Company’s outstanding Voting Securities immediately prior to such transaction (treating, for purposes of determining whether the 70% continuity test is met, any ownership of the Voting Securities of the surviving or resulting corporation or entity that results from a stockholder’s ownership of the stock of, or other ownership interest in, the corporation or other entity with which the Company is merged or consolidated as not owned by persons who were beneficial owners of the Company’s outstanding Voting Securities immediately prior to the transaction); or

(iv)                              all or substantially all of the assets of the Company are sold or transferred to a Person as to which (A) the Incumbent Board does not have authority (whether by law or contract) to directly control the use or further disposition of such assets and (B) the financial results of the Company and such Person are not consolidated for financial reporting purposes.

10.                                 Gross-Up.  (a) If any benefit or payment by the Company or a successor (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, including any acceleration of vesting or payment) (a “Payment”) is determined to be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties are incurred by Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, being herein collectively referred to as the “Excise Tax”), then Executive shall be entitled to receive an additional payment (the “Gross-Up Payment”) in an amount such that the net amount of such additional payment retained by Executive, after payment of all federal, state and local income and employment taxes (including, without limitation, any federal, state and local income and employment taxes and Excise Tax imposed on the Gross-Up Payment), shall be equal to the Excise Tax imposed on the Payment.

(b)                                 Subject to the provisions of Section 10(c), all determinations required to be made under this Section 10, including whether and when a Gross-Up Payment is required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by an independent accounting firm of nationally recognized standing selected by the Company and which is not serving as accountant or auditor for the Company or the individual, entity or group effecting the Change in Control (the “Accounting Firm”).  The Accounting Firm shall provide detailed supporting calculations both to the Company and Executive within 15 business days of the receipt of the notice from Executive that there has been a Payment or such earlier time as is requested by the Company.  Any Gross-Up Payment shall be paid by the Company to Executive within ten business days of the receipt of the Accounting Firm’s determination.  Any determination by the Accounting Firm shall be binding upon the Company and Executive.  As a result of the uncertainty in the application of

13

Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments will not have been made by the Company which should have been made (“Underpayment”), consistent with the calculations required to be made hereunder.  In the event that the Company exhausts its remedies pursuant to Section 10(c), and Executive is thereafter required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred, and the amount of the Underpayment shall be promptly paid by the Company to or for Executive’s benefit.

(c)                                  Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of a Gross-Up Payment.  Such notification shall be given as soon as practicable but no later than ten business days after Executive is informed in writing of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid.  Executive shall not pay such claim prior to the expiration of the 30-day period following the date on which Executive gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due).  If the Company notifies Executive in writing prior to the expiration of such period that it desires to contest such claim, Executive shall:

(i)                                     give the Company any information reasonably requested by the Company relating to such claim;

(ii)                                  take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including without limitation accepting legal representation with respect to such claim by an attorney reasonably selected by the Company;

(iii)                               cooperate with the Company in good faith in order effectively to contest such claim; and

(iv)                              permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company 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 Executive harmless, on an after-tax basis, for any Excise Tax or federal, state and local income and employment 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 Section 10(c), the Company 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 Executive to pay the tax claimed and sue for a refund or to contest the claim in any permissible manner, and 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 the Company shall determine; provided, however, that if the Company directs Executive to pay such claim and sue for a refund, the Company shall pay and assume all responsibility for the tax; and further provided that any extension of the statute of limitations relating to payment of taxes for

14

Executive’s taxable year with respect to which such contested amount is claimed to be due is limited solely to such contested amount.  The Company’s control of the contest, however, shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder, and Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.

(d)                                 If, after the Company’s payment of tax pursuant to Section 10(c), Executive becomes entitled to receive any refund with respect to such claim, Executive shall (subject to the Company’s complying with the requirements of Section 10(c)) promptly pay over to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto).  If, after the Company’s payment of tax pursuant to Section 10(c), a determination is made that Executive shall not be entitled to any refund with respect to such claim and the Company does not notify Executive in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such payment shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid.

(e)                                  In the event that the Excise Tax is subsequently determined to be less than initially determined by the Accounting Firm, Executive shall pay to the Company at the time that the amount of such reduction in Excise Tax is determined (but, if previously paid to the taxing authorities, not prior to the time the amount of such reduction is refunded to Executive or otherwise realized as a benefit by Executive) the portion of the Gross-Up Payment that would not have been paid if the Excise Tax as subsequently determined had been applied in initially calculating the Gross-Up Payment, with the amount of such repayment determined by the Accounting Firm.

11.                                 Arbitration.  Any dispute or controversy arising under, related to or in connection with this Agreement shall be settled exclusively by arbitration before a single arbitrator in New York, New York, in accordance with the Commercial Arbitration Rules of the American Arbitration Association.  The arbitrator’s award shall be final and binding on all parties to this Agreement.  Judgment may be entered on an arbitrator’s award in any court having competent jurisdiction.

12.                                 Assignment.  This Agreement is personal to Executive and shall not be assignable by Executive.  This Agreement shall inure to the benefit of and be enforceable by Executive and Executive’s legal representatives and heirs.  This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns.  The Company shall require any successor (by merger or otherwise) to expressly assume this Agreement.

13.                                 Mitigation/Set Off.  The Company’s obligation to pay Executive the amounts provided and to make the arrangements provided hereunder shall not be subject to set-off, counterclaim or recoupment of amounts owed by Executive to the Company or its affiliates except, to the extent permitted by Section 409A, for any specific, stated amounts owed by the Executive to the Company.  In the event of any termination of employment hereunder, the Executive shall be under no obligation to seek other employment and there shall be no offset against any amounts due Executive under this Agreement on account of any remuneration attributable to any subsequent employment that Executive may obtain.

15

14.                                 Severability.  A determination that any provision of this Agreement is invalid or unenforceable shall not affect the validity or enforceability of any other provision hereof.  Any provision of this Agreement which is rendered or held invalid, illegal or unenforceable in any respect in any jurisdiction shall be ineffective, but such ineffectiveness shall be limited as follows: (a) if such provision is rendered or held invalid, illegal or unenforceable in such jurisdiction only as to a particular person or persons or under any particular circumstance or circumstances, such provision shall be ineffective, but only in such jurisdiction and only with respect to such particular person or persons or under such particular circumstance or circumstances, as the case may be; (b) without limitation of clause (a), such provision shall in any event be ineffective only as to such jurisdiction and only to the extent of such invalidity, illegality or unenforceability, and such invalidity, illegality or unenforceability in such jurisdiction shall not render invalid, illegal or unenforceable such provision in any other jurisdiction; and (c) without limitation of clause (a) or (b), such ineffectiveness shall not render invalid, illegal or unenforceable this Agreement or any of the remaining provisions hereof.

15.                                 Withholding.  The Company may withhold from any amounts payable under this Agreement such federal, state, local or foreign taxes as shall be required to be withheld pursuant to any applicable law or regulation.

16.                                 Governing Law.  This Agreement shall be governed by and construed in accordance with the law of the State of New York without reference to principles of conflicts of law.

17.                                 Entire Agreement.  This Agreement constitutes the entire Agreement between the parties with respect to the subject matter hereof and supersedes in its entirety any and all prior agreements, understandings, or representations relating to the subject matter hereof, including the Agreement between Rockwood Specialties Inc. (“RSI”) and the Executive dated March 21, 2001, as amended by the Letter Agreement between RSI and the Executive dated October 19, 2004.  No modification of this Agreement shall be valid unless made in writing and signed by the parties hereto.

18.                                 Interpretation.  All parties have participated jointly in the negotiation and drafting of this Agreement.  In the event any ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Company and Executive and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed and delivered as of the day and year first above set forth.
