KOPPERS HOLDINGS INC.

RESTRICTED STOCK UNIT ISSUANCE AGREEMENT

NON-EMPLOYEE DIRECTOR—TIME VESTING

RECITALS

A. The Board has adopted the Plan for the purpose of retaining the services of selected employees, non-employee members of the Board (or the board of directors of any Parent or Subsidiary) and consultants and other independent advisors who provide services to the Corporation (or any Parent or Subsidiary).

B. Participant is to render valuable services to the Corporation, and this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection with the Corporation’s issuance of shares of Common Stock to Participant under the Plan.

C. All capitalized terms in this Agreement shall have the meaning assigned to them in this Agreement or the attached Appendix A.

NOW, THEREFORE, it is hereby agreed as follows:

1. Grant of Restricted Stock Units. The Corporation hereby awards Restricted Stock Units to the Participant under the Plan. The number of shares of Common Stock subject to the awarded Restricted Stock Units, the vesting provisions for those shares, the date on which the vested shares shall become issuable to Participant and the remaining terms and conditions governing the Award shall be as set forth in this Agreement.

AWARD SUMMARY

2. Limited Transferability. Prior to the actual issuance of the Shares which vest hereunder, Participant may not transfer any interest in the Award or the underlying Shares; provided, however, any Shares which vest hereunder but which otherwise remain unissued at the time of Participant’s death may be transferred pursuant to the provisions of Participant’s will or the laws of inheritance or to Participant’s designated beneficiary or beneficiaries of this Award. Participant may make a beneficiary designation for this Award at any time by filing the appropriate form with the Plan Administrator or its designee.

3. Stockholder Rights and Dividend Equivalents

(a) The holder of this Award shall not have any stockholder rights, including voting or dividend rights, with respect to the Shares subject to the Award until Participant becomes the record holder of those Shares following their actual issuance.

(b) Notwithstanding the foregoing, should any stock dividend, whether regular or extraordinary, be declared and paid on the outstanding Common Stock while one or more Shares remain subject to this Award (i.e., those Shares are not otherwise issued and outstanding for purposes of entitlement to the dividend or distribution), then Participant shall automatically be credited with an additional number of Restricted Stock Units equal to the number of shares of Common Stock which would have been paid on the Shares (plus the number of additional shares previously credited to Participant pursuant to the dividend equivalent right provisions of this Paragraph 3) at the time subject to this Award had those Shares been actually issued and outstanding and entitled to that dividend. The additional Restricted Stock Units so credited shall vest at the same time as the Shares to which they relate and shall be distributed to Participant concurrently with the issuance of those Shares on the applicable Issue Date.

(c) Notwithstanding the foregoing, should any cash dividend, whether regular or extraordinary, be declared and paid on the outstanding Common Stock while one or more Shares remain subject to this Award (i.e., those Shares are not otherwise issued and outstanding for purposes of entitlement to the dividend or distribution), then a special book account shall be established for Participant and credited with a dollar amount equal to the amount of that dividend paid per share multiplied by the number of Restricted Stock Units at the time subject to this Award (plus the number of additional shares previously credited to Participant pursuant to the dividend equivalent right provisions of this Paragraph 3) as of the record date for the dividend. As of the fifteenth business day in April each year, the cash dividend amounts credited to the special book account since the Award Date shall be converted into a book entry of an additional number of Restricted Stock Units determined by dividing (i) those cash dividend equivalent amounts by (ii) the average of the Fair Market Value per share of Common Stock on each of the dates since the Award Date on which those dividends on the outstanding Common Stock were paid. The additional Restricted Stock Units so credited shall vest at the same time as the Shares to which they relate and shall be distributed to Participant concurrently with the issuance of those Shares on the applicable Issue Date.

4. Special Vesting/Change in Control.

(a) Should Participant’s Service terminate for any reason prior to the Vesting Date, then, on the date of such termination, Participant shall vest in a number of Shares equal to the number of Shares in which Participant would have been vested on the Vesting Date had Participant continued in the Corporation’s Service through the Vesting Date multiplied by a fraction, the numerator of which is the number of days of Service Participant completed between the Award Date and the termination of Participant’s Service, and the denominator of which is three hundred sixty-five (365).

2

(b) Immediately prior to the closing of a Change in Control, Participant shall vest in a number of Shares equal to the number of Shares in which Participant would have vested on the Vesting Date. The Shares that vest under this subparagraph (b) will be issued on the Issue Date triggered by the Change in Control (or otherwise converted into the right to receive the same consideration per share of Common Stock payable to the other stockholders of the Corporation in consummation of that Change in Control and distributed at the same time as such stockholder payments). For purposes of this Section 4(b), the Issue Date shall be the effective date of the Change in Control so long as it qualifies as a “change in the ownership or effective control” of the Corporation within the meaning of Section 409A(a)(2)(A)(v) of the Code and regulations thereunder. If it does not so qualify, the Issue Date shall be the Vesting Date.

(c) This Agreement shall not in any way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

5. Adjustment in Shares. In the event of any of the following transactions affecting the outstanding shares of Common Stock as a class without the Corporation’s receipt of consideration: any stock split, stock dividend, spin-off transaction, extraordinary distribution (whether in cash, securities or other property), recapitalization, combination of shares, exchange of shares or other similar transaction affecting the outstanding Common Stock as a class without the Corporation’s receipt of consideration or in the event of a substantial reduction to the value of the outstanding shares of Common Stock by reason of a spin-off transaction or extraordinary distribution, then equitable adjustments shall be made to the total number and/or class of securities issuable pursuant to this Award in such manner as the Plan Administrator deems appropriate in order to reflect such change and thereby prevent the dilution or enlargement of benefits hereunder. In determining such adjustments, the Plan Administrator shall take into account any amounts credited to Participant pursuant to the dividend equivalent right provisions of Paragraph 3 in connection with such transaction, and the determination of the Plan Administrator shall be final, binding and conclusive.

6. Compliance with Laws and Regulations. The issuance of shares of Common Stock pursuant to the Award shall be subject to compliance by the Corporation and Participant with all applicable requirements of law relating thereto and with all applicable regulations of any stock exchange on which the Common Stock may be listed for trading at the time of such issuance.

7. Notices. Any notice required to be given or delivered to the Secretary of the Corporation under the terms of this Agreement shall be in writing and addressed to the Corporation at its principal corporate office at 436 Seventh Avenue, Pittsburgh, PA 15219. Except to the extent electronic notice is expressly authorized hereunder, any notice required to be given or delivered to Participant shall be in writing and addressed to Participant at the address indicated below Participant’s signature line on this Agreement. All notices shall be deemed effective upon personal delivery (or electronic delivery to the extent authorized hereunder) or upon deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified.

8. Successors and Assigns. Except to the extent otherwise provided in this Agreement, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Corporation and its successors and assigns and Participant, Participant’s assigns, the legal representatives, heirs and legatees of Participant’s estate and any beneficiaries of the Award designated by Participant.

9. Construction. This Agreement and the Award evidenced hereby are made and granted pursuant to the Plan and are in all respects limited by and subject to the terms of the Plan. All decisions of the Plan Administrator with respect to any question or issue arising under the Plan or this Agreement shall be conclusive and binding on all persons having an interest in the Award.

10. Governing Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the Commonwealth of Pennsylvania without resort to Pennsylvania’s conflict-of-laws rules.

11. Service at Will. Nothing in this Agreement or in the Plan shall confer upon Participant any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Corporation (or any Parent or Subsidiary employing or retaining Participant) or of Participant, which rights are hereby expressly reserved by each, to terminate Participant’s Service at any time for any reason, with or without cause, unless such rights are otherwise limited pursuant to a separate agreement between the Corporation (or any Parent or Subsidiary) and Participant.

IN WITNESS WHEREOF, the parties have executed this Agreement on the day and year first indicated above.
