KOPPERS INC.

SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN II

PREAMBLE

Koppers Inc. (the “Company”) recognizes that the Internal Revenue Service limitations on compensation that may be taken into account for purposes of determining retirement benefits under a retirement plan qualified under Section 401(a) of the Internal Revenue Code may prevent some key employees from realizing sufficient benefits from the Company’s qualified retirement plan. The purpose of the Koppers Inc. Supplemental Executive Retirement Plan II (formerly named the Koppers Industries, Inc. Supplemental Executive Retirement Plan II) is to acknowledge and reward certain key employees of the Company for their efforts on behalf of the Company by providing additional post employment income to such key employees in order to facilitate their attainment of adequate levels of retirement income.

ARTICLE I

GENERAL

Section 1.1Effective Date; Grandfathered Benefits. The original effective date of the Plan was December 1, 1997 and the Plan was subsequently amended and restated, effective as of January 1, 2009. The Plan as amended and restated as of such date applies only to a Participant’s Retirement Benefit that accrued on or after January 1, 2005, or Retirement Benefit that accrued prior to that date but was not fully vested on December 31, 2004. The Plan preceding such amendment and restatement applies to any Retirement Benefit that accrued and was vested prior to January 1, 2005 (“Grandfathered Benefits”); provided that any increase in the value of any subsidy with respect to Grandfathered Benefits payable upon retirement prior to the Retirement Plan’s Normal Retirement Date that accrues or increases as the result of service after December 31, 2004, shall not be treated as Grandfathered Benefits. The rights, if any, of any person whose status as an employee of an Employer has terminated shall be determined pursuant to the Plan as in effect on the date such employee terminated, unless a subsequently adopted provision of the Plan is made specifically applicable to such person. Notwithstanding the foregoing, the Plan is hereby restated to clarify the intended meaning of the Plan’s early retirement date definition and early retirement benefit provisions, with such clarification being effective as of the Plan’s original effective date.

Section 1.2Intent. The Plan is intended to be an unfunded plan maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees, as such group is described under Section 201(2), 301(a)(3), and 401(a)(1) of ERISA. Benefits provided under this Plan shall be funded solely from the general assets of the Employer and no participant or beneficiary hereunder shall have any interest or right to such assets.

4

opportunity to remedy such identified failure to perform, or (b) the willful engaging by the Participant in conduct which is demonstrably and materially injurious to the Employer, monetarily or otherwise. For purposes of this definition, no act or failure to act, shall be deemed “willful” unless done, or omitted to be done, not in good faith and without reasonable belief that such action or omission was in the best interest of the Employer.

Notwithstanding the foregoing, a Participant shall not be considered to have been terminated for cause unless there is delivered to the Participant a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters (3/4) of the entire membership of the Board at a meeting of the Board called and held for such purpose (after reasonable notice to the Participant and an opportunity for the Participant, with legal counsel, to be heard before the Board), finding that in the good faith opinion of the Board, the Participant was engaged in the type of conduct set forth above in this definition, which specifies particular details and examples of such conduct.

“Years of Service” means the total number of years of “credited service” (as defined in the Retirement Plan) credited to a Participant under the Retirement Plan. In no event shall more than thirty-five (35) years be credited to any Participant, regardless of his or her actual period of service with the Employer or the number of years of credited service accumulated by the Participant under the Retirement Plan. At the discretion of the Administrator, Participants may be granted additional Years of Service that relate to employment with another employer for purposes of determining Retirement Benefits under this Plan, upon such terms and conditions as the Administrator may require (which conditions may include, but not be limited to, completion of a period of future service with the Employer and reducing the Participant’s Retirement Benefit hereunder by the pension benefits provided by such other employer).

Section 9.6Severability.
