SECTION 2 — SEPARATION PAY AND CONSULTING PERIOD

For purposes of this Agreement, the period from June 11, 2003 through August 3, 2005 will hereinafter be referred to as the “Separation Pay and Consulting Period.”

A. Payment: During the Separation Pay and Consulting Period (i.e., from June 11, 2003 through August 3, 2005), Koppers agrees to provide to ▇▇. ▇▇▇▇▇, and ▇▇. ▇▇▇▇▇ agrees to accept from Koppers, the following items:

(1) During the Separation Pay and Consulting Period, ▇▇. ▇▇▇▇▇ shall continue to receive from Koppers his regular monthly salary of Twenty Thousand One Hundred Twenty-Five Dollars ($20,125.00), less deductions required by law, payable on the regular Koppers pay dates. ▇▇. ▇▇▇▇▇ expressly acknowledges (a) that a portion of the continuation of his salary during the Separation Pay and Consulting Period, to-wit 24 weeks and 4 days, constitutes the equivalent of benefits to which he is entitled under the Severance Pay Program and is being paid to him in installments during the Separation Pay and Consulting Period at his election and request and in lieu of payment to him by Koppers on or after August 3, 2005; (b) that a portion of the continuation of his salary

2

during the Separation Pay and Consulting Period, to-wit 8 weeks, constitutes the equivalent of his accrued and unused vacation benefits to which he is entitled and is being paid to him in installments during the Separation Pay and Consulting Period at his election and request and in lieu of a lump sum payment to him by Koppers; and (c) that the remaining portion of the continuation of his salary during the Separation Pay and Consulting Period, to-wit 79 weeks and 3 days, relates to Koppers employment of ▇▇. ▇▇▇▇▇ as a consultant and is in excess of that to which he is eligible under the aforesaid Separation Pay Program and, further, is in addition to anything of value to which ▇▇. ▇▇▇▇▇ is entitled under Koppers’ policies and procedures.

(2) During the Separation Pay and Consulting Period or until ▇▇. ▇▇▇▇▇ is covered under another employer’s program of insurance benefits, whichever shall first occur, and as long as ▇▇. ▇▇▇▇▇ elects to continue coverage and pays the employee share of premiums, where applicable, ▇▇. ▇▇▇▇▇ and his eligible dependents will continue to be covered under the following insurance plans of Koppers: (a) Comprehensive Medical Benefits Plan of Koppers Inc. for Salaried Employees; (b) Dental Expense Plan for Salaried Employees of Koppers Inc.; (c) Group Life Insurance Plan of Koppers Inc. for Salaried Employees; (d) Personal and Family Accident Insurance Plan of Koppers Inc. for Salaried Employees; and (e) Koppers Inc. Survivor Benefit Plan.

(3) During the Separation Pay and Consulting Period, ▇▇. ▇▇▇▇▇ will continue to receive service credit for purposes of determining the benefits to which ▇▇. ▇▇▇▇▇ may be entitled under the Retirement Plan of Koppers Industries, Inc. and Subsidiaries for Salaried Employees (the “Pension Plan”); provided, however, that if the Pension Plan is terminated, frozen or otherwise amended prior to August 3, 2005, then ▇▇. ▇▇▇▇▇ shall have no greater right to benefits or benefit accruals under the Pension Plan than the other participants in the Pension Plan.

(4) During the Separation Pay and Consulting Period, ▇▇. ▇▇▇▇▇ will continue to be eligible to participate in the Employee Savings Plan of Koppers Industries, Inc. and Subsidiaries (the “401(k) Plan”).

(5) During the Separation Pay and Consulting Period, ▇▇. ▇▇▇▇▇ will continue to receive service and compensation credit through August 3, 2005 under the two non-qualified supplemental executive retirement (“SERP”) plans sponsored by Koppers in which ▇▇. ▇▇▇▇▇ currently participates, and the amount, form and timing of the commencement of pension benefits thereunder following the termination of ▇▇. ▇▇▇▇▇’▇ employment shall be as set forth under the terms of such plans; provided, however, that if either or both of the SERP Plans are terminated, frozen or otherwise amended prior to August 3, 2005, then ▇▇. ▇▇▇▇▇ shall have no greater right to benefits or benefit accruals under the SERP Plans than the other participants in such plans.

(6) During the Separation Pay and Consulting Period, ▇▇. ▇▇▇▇▇ will remain eligible to participate in the Salary Continuation Plan of Koppers Inc. and in the Long Term Disability Plan of Koppers Inc. for Salaried Employees (the “LTD Plan”). At Koppers’ sole discretion, should ▇▇. ▇▇▇▇▇ receive any benefits during said Separation Pay and Consulting Period under either Plan, Koppers will be entitled to offset the benefits received, dollar for dollar, against all amounts to be paid pursuant to subparagraph (1) above.

All severance and vacation pay due will be completed by the “Pay-Through-Date” of August 3, 2005, at which time ▇▇. ▇▇▇▇▇’▇ benefits as a severed employee will end.

3

B. Other Employment/Non-Competition: If ▇▇. ▇▇▇▇▇ finds other employment prior to August 3, 2005 he may accept such other employment, without any impairment or offset of the payments set forth in Section 2, paragraph A provided that he does not, in the course of or in connection with such employment, breach any of the covenants set forth in this Agreement and provided further that he does not (during the Separation Pay and Consulting Period) engage, directly or indirectly, whether as principal or as agent, officer, director, employee, consultant, or shareholder, alone or in association with any other person, corporation or other entity, in any Competing Business. For purposes of this Agreement, the term “Competing Business” shall mean any person, corporation or other entity engaged anywhere in the world in the same business as Koppers, which is a global integrated producer of carbon compounds and treated wood products for use in a variety of markets including the railroad, aluminum, chemical, and steel industries. ▇▇. ▇▇▇▇▇ recognizes and acknowledges that Koppers conducts business on a national and international basis, and therefore, ▇▇. ▇▇▇▇▇ agrees that this restriction is reasonable and necessary to protect Koppers’ business. ▇▇. ▇▇▇▇▇ also covenants and agrees that, during the Separation Pay and Consulting Period, he shall not, directly or indirectly, solicit or induce, or attempt to solicit or induce, any employee of Koppers to leave Koppers for any reason whatsoever, or hire any employee of Koppers; and he shall not, directly or indirectly, solicit the business of, or do business with, any customer or prospective customer or supplier of Koppers for any business purpose other than for the benefit of Koppers.

C. Sufficiency of Consideration: ▇▇. ▇▇▇▇▇ expressly acknowledges that, during the Separation Pay and Consulting Period and otherwise, he shall not receive any payments or benefits from Koppers other than those specified above and that Koppers shall not be required to make any further payment or provide any further benefit to him or on his behalf, for any reason whatsoever, either during the Separation Pay and Consulting Period or thereafter. ▇▇. ▇▇▇▇▇ acknowledges and agrees that Koppers’ entry into a consulting arrangement with him as described in Section 1; Koppers’ agreement to pay him his regular salary for a period of 79 weeks and 3 days, as described in paragraph A above; the continuation of certain pension service credit accrual; and the outplacement services as described in paragraph D below, are significantly and substantially in addition to those benefits to which ▇▇. ▇▇▇▇▇ was or is otherwise entitled and ▇▇. ▇▇▇▇▇ acknowledges that these undertakings by Koppers are adequate consideration for all terms and covenants contained in this Agreement.

D. Outplacement: Koppers will assist ▇▇. ▇▇▇▇▇ in finding employment with an employer other than Koppers (or its related companies or subsidiaries) by making available to ▇▇. ▇▇▇▇▇, at Koppers’ expense up to Fifteen Thousand Dollars ($15,000.00), the outplacement services of Drake Beam. The cost of said services will be paid by Koppers directly to Drake Beam, and ▇▇. ▇▇▇▇▇ must commence utilizing the services by July 15, 2003 or they will not be available to him. If ▇▇. ▇▇▇▇▇ desires to utilize these services, he should contact ▇▇▇▇▇▇ ▇▇▇▇ at (▇▇▇) ▇▇▇-▇▇▇▇.

C. Claims Released: ▇▇. ▇▇▇▇▇ understands and agrees that he is releasing all known and unknown claims, promises, causes of action, or similar rights of any type that he may have (the “Claims”) against any Released Party arising out of or in any way related to his employment with Koppers, the terms and conditions of his employment with Koppers, the end of ▇▇. ▇▇▇▇▇’▇ employment as the Vice President & Chief Financial Officer of Koppers and a member of Koppers’ Senior Management, the final termination of his employment with Koppers on August 3, 2005, and the continuing effects thereof. ▇▇. ▇▇▇▇▇ further understands that the Claims he is releasing may arise under many different laws and under any possible legal, equitable, statutory, contractual or tort theory, including, but by no means limited to:

(1) Anti-discrimination statutes, such as the Age Discrimination in Employment Act and Executive Order 11141, which prohibit age discrimination in employment; Title VII of the Civil Rights Act of 1964, Section 1981 of the Civil Rights Act of 1866, and Executive Order 11246, which prohibit discrimination or harassment based on race, color, national origin, religion, or sex; the Equal Pay Act, which prohibits paying men and women unequal pay for equal work; the Americans With Disabilities Act and Sections 503 and 504 of the Rehabilitation Act of 1973, which prohibit discrimination based on disability; the Pennsylvania Human Relations Act, which prohibits discrimination based on age, race, sex, non-job related handicap or disability; and any other federal, state, or local laws prohibiting employment or wage discrimination.

(4) Tort and Contract Claims, such as Claims for wrongful or constructive discharge, physical or personal injury, emotional distress, fraud, fraud in the inducement, negligent misrepresentation, defamation, invasion of privacy, interference with contract or with prospective economic advantage, breach of express or implied contract, breach of covenants of good faith and fair dealing, and similar or related claims.

▇▇. ▇▇▇▇▇ understands that he is releasing Claims that he may not know about. That is ▇▇. ▇▇▇▇▇’▇ knowing and voluntary intent, even though ▇▇. ▇▇▇▇▇ recognizes that someday he might learn that some or all of the facts that he currently believes to be true are untrue and even though he might then regret having signed this Agreement. Nevertheless, ▇▇. ▇▇▇▇▇ is assuming that risk and he agrees that this Agreement shall remain effective in all respects in any such case.

5

That is his knowing and voluntary intent. ▇▇. ▇▇▇▇▇ also covenants that, to his knowledge, he has not sustained any work-related injury during his employment at Koppers.

C. No Limitation: Except for vested rights, ▇▇. ▇▇▇▇▇ acknowledges and agrees that no provision of this Agreement referencing his participation in any Koppers employee benefit plan, program, or policy shall be deemed to limit any rights Koppers may have to amend or terminate such plan, program, or policy in accordance with its terms and applicable laws.

D. Taxes: ▇▇. ▇▇▇▇▇ agrees that he is solely responsible for any tax liabilities and consequences which may result from his receipt of money under this Agreement, and ▇▇. ▇▇▇▇▇ agrees that Koppers shall bear absolutely no responsibility for any such tax liabilities or consequences. ▇▇. ▇▇▇▇▇ shall indemnify and hold Koppers harmless from any liability for tax payments, tax withholdings, penalties, additions to tax and/or interest which may result from any payment under this Agreement. Further, ▇▇. ▇▇▇▇▇ agrees that Koppers shall not be required to pay any further sum to him, or to any other person or entity, for any reason as part of this

6

settlement even if the tax liabilities and consequences to ▇▇. ▇▇▇▇▇ are ultimately assessed in a fashion which he does not presently anticipate.

E. Indemnification: ▇▇. ▇▇▇▇▇ hereby releases, indemnifies and holds the Released Parties harmless of and from any and all claims or causes of action for the fees, costs and expenses of any and all attorneys who have at any time or are now representing ▇▇. ▇▇▇▇▇ in connection with the underlying dispute or with the matters which are the subject of this Agreement.

F. Ownership of Claims: ▇▇. ▇▇▇▇▇ has not assigned or transferred any Claim he is releasing, nor has he purported to do so.

G.

Further, ▇▇. ▇▇▇▇▇ agrees that Koppers entry into this Agreement is not to be construed as, and is not, an admission that Koppers violated any of its duties or obligations to him or treated him improperly, unlawfully or unfairly in any manner whatsoever.

H. Implementation: ▇▇. ▇▇▇▇▇ agrees to sign any documents and do anything else that is necessary in the future to implement this Agreement.

I. Confidential Information: ▇▇. ▇▇▇▇▇ hereby acknowledges that during the course of his employment he gained knowledge or information of a confidential nature in which Koppers has a proprietary interest. ▇▇. ▇▇▇▇▇ agrees not to disclose to any person or any entity, without the express written authorization and consent of Koppers, any confidential, proprietary or competitive information belonging to Koppers or its subsidiaries or affiliates, including without limitation confidential manufacturing processes, inventions, devices, cost data, marketing information, capital spending or other business plans or strategies, pricing information, customer lists, forecasts, personnel or employment information, legal plans or strategies or any other information not disclosed to the public or otherwise generally available to the public or known by Koppers’ competitors.

J. This Agreement To Be Kept Confidential: ▇▇. ▇▇▇▇▇ agrees not to disclose the terms or amount of this Agreement to anyone other than members of his immediate family, his attorney, and other professional advisors and, even as to such persons, only if they agree to honor this confidentiality requirement. Such a person’s violation of this confidentiality requirement will be treated as a violation of this Agreement by ▇▇. ▇▇▇▇▇. This subsection does not prohibit the disclosure of the terms or amount of this Agreement to the extent necessary legally to enforce this Agreement, nor does it prohibit disclosures to the extent otherwise legally required. ▇▇. ▇▇▇▇▇ acknowledges that Koppers would be irreparably harmed if this subsection were violated.

K. Consequence of Violating Any Promises: ▇▇. ▇▇▇▇▇ agrees to pay the reasonable attorneys’ fees and any damages any Released Party may incur as a result of ▇▇. ▇▇▇▇▇ breaching a promise he made in this Agreement (such as suing a Released Party over a released Claim that is later determined by a Court to have been waived and released under this Agreement) or if any representation he made in this Agreement was false when made or by violating the confidentiality provisions of this Section 4. ▇▇. ▇▇▇▇▇ further agrees that Koppers would be irreparably harmed by any actual or threatened violation of Section 4 that involves disclosure of

7

the terms or amount payable under this Agreement, and that Koppers (in addition to the remedies in subsection J above) will be entitled to an injunction prohibiting him from committing any such violation.
