 KOPPERS HOLDINGS INC. 

STOCK OPTION AGREEMENT 

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. Optionee is to render valuable services to the Corporation (or a Parent or
Subsidiary), and this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection with the Corporation’s grant of an option to Optionee. 

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

NOW, THEREFORE, it is hereby agreed as follows: 
 1. Grant of Option. The Corporation hereby grants to Optionee, as of the Grant Date, an option to purchase up to the number of Option Shares specified in the Grant Notice. The Option Shares shall
be purchasable from time to time during the option term specified in Paragraph 2 at the Exercise Price. 
 2. Option
Term. This option shall have a maximum term of ten (10) years measured from the Grant Date and shall accordingly expire at the close of business on the Expiration Date, unless sooner terminated in accordance with Paragraph 5, 6 or 11.

 3. Limited Transferability. 
 (a) This option shall be neither transferable nor assignable by Optionee other than by will or the laws of inheritance following Optionee’s death and may be exercised, during Optionee’s
lifetime, only by Optionee. However, Optionee may designate one or more persons as the beneficiary or beneficiaries of this option, and this option shall, in accordance with such designation, automatically be transferred to such beneficiary or
beneficiaries upon the Optionee’s death while holding this option. Such beneficiary or beneficiaries shall take the transferred option subject to all the terms and conditions of this Agreement, including (without limitation) the limited time
period during which this option may, pursuant to Paragraph 5, be exercised following Optionee’s death. 
 (b) If this
option is designated a Non-Statutory Option in the Grant Notice, then this option may be assigned in whole or in part during Optionee’s lifetime to one or more of the Optionee’s Family Members or to a trust established for the exclusive
benefit of Optionee and/or one or more such Family Members, to the extent such assignment is in connection with the Optionee’s estate plan or pursuant to a domestic relations order. The assigned portion shall be exercisable only by the person
or persons who acquire a proprietary interest in the option pursuant to such assignment. The terms applicable to the assigned portion shall be the same as those in effect for this option immediately prior to such assignment. 

  
 3 








 4. Dates of Vesting. This option shall become exercisable for the Option Shares in
one or more installments in accordance with the Vesting Schedule set forth in the Grant Notice. As the option becomes exercisable for such installments, those installments shall accumulate, and the option shall remain exercisable for the accumulated
installments until the Expiration Date or sooner termination of the option term under Paragraph 5, 6 or 11. 
 5. Cessation
of Service. The option term specified in Paragraph 2 shall terminate (and this option shall cease to be outstanding) prior to the Expiration Date should any of the following provisions become applicable: 

(a) Except as otherwise provided in subparagraphs (b), (c), (d), (e) and (h) of this Paragraph 5, should Optionee cease to
remain in Service for any reason while this option is outstanding, then Optionee (or any person or persons to whom this option is transferred pursuant to a permitted transfer under Paragraph 3) shall have a ninety (90)-day period during which to
exercise this option, measured from the date of such cessation of Service (or, if later, measured from the three (3)-year anniversary of the Vesting Commencement Date in the event that Optionee’s Service terminates by reason of his termination
of employment by the Corporation without Cause), but in no event shall this option be exercisable at any time after the Expiration Date. 
 (b) Should Optionee cease to remain in Service due to Optionee’s voluntary resignation while this option is outstanding, then Optionee (or any person or persons to whom this option is transferred
pursuant to a permitted transfer under Paragraph 3) shall have a thirty (30)-day period measured from the date of such cessation of Service during which to exercise this option, but in no event shall this option be exercisable at any time after the
Expiration Date. 
 (c) Should Optionee die while this option is outstanding, then this option may be exercised by (i) the
personal representative of Optionee’s estate or (ii) the person or persons to whom the option is transferred pursuant to Optionee’s will or the laws of inheritance following Optionee’s death or to whom the option is transferred
during Optionee’s lifetime pursuant to a permitted transfer under Paragraph 3, as the case may be. However, if Optionee dies while holding this option and has an effective beneficiary designation in effect for this option at the time of his
death, then the designated beneficiary or beneficiaries shall have the exclusive right to exercise this option following Optionee’s death. Any such right to exercise this option shall lapse, and this option shall cease to be outstanding, upon
the earlier of (i) the expiration of the twelve (12)-month period measured from the date of Optionee’s death or (ii) the Expiration Date. 
 (d) Should Optionee cease Service by reason of Permanent Disability while this option is outstanding, then Optionee (or any person or persons to whom this option is transferred pursuant to a permitted
transfer under Paragraph 3) shall have a twelve (12)-month period measured from the date of such cessation of Service during which to exercise this option. In no event shall this option be exercisable at any time after the Expiration Date.

 (e) Should Optionee cease Service by reason of Retirement while this option is outstanding, then Optionee (or any person or
persons to whom this option is transferred pursuant to a permitted transfer under Paragraph 3) shall have a five (5)-year period during which to exercise this option, measured from the date of Optionee’s Retirement (or, if later, measured from
the date on which he becomes fully vested in this Option under Section 

  
 4 








 
6(a) by reason of Retirement on or after December 31, 2014), but in no event shall this option be exercisable at any time after the Expiration Date. 

(f) The applicable period of post-Service exercisability in effect pursuant to the foregoing provisions of this Paragraph 5 shall
automatically be extended by an additional period of time equal in duration to any interval within such post-Service exercise period during which the exercise of this option or the immediate sale of the Option Shares acquired under this option
cannot be effected in compliance with applicable federal and state securities laws, but in no event shall such an extension result in the extension of this option beyond the Expiration Date. 

(g) During the limited period of post-Service exercisability, this option may not be exercised in the aggregate for more than the number
of Option Shares for which this option is, at the time of Optionee’s cessation of Service, vested and exercisable pursuant to the Exercise Schedule specified in the Grant Notice or the special vesting acceleration provisions of Paragraph 6.
This option shall not vest or become exercisable for any additional Option Shares, whether pursuant to the normal Exercise Schedule specified in the Grant Notice or the special vesting acceleration provisions of Paragraph 6, following the
Optionee’s cessation of Service, except to the extent (if any) specifically authorized by the Plan Administrator pursuant to an express written agreement with the Optionee. Upon the expiration of such limited exercise period or (if earlier)
upon the Expiration Date, this option shall terminate and cease to be outstanding for any exercisable Option Shares for which the option has not otherwise been exercised. 
 (h) Should Optionee’s Service be terminated for Cause or should Optionee otherwise engage in any Cause while this option is outstanding, then this option shall terminate immediately and cease to
remain outstanding. 
 6. Special Acceleration of Option. 

(a) Should Optionee’s Service terminate by reason of his termination of employment by the Corporation without Cause or his
Retirement on or after December 31, 2014, the Optionee shall continue to vest in his Option Shares to the same extent had the Optionee continued in the Corporation’s Service through the three (3) year anniversary of the Vesting
Commencement Date. Should Optionee’s Service terminate by reason of his death or Permanent Disability, then Optionee shall immediately vest in all then outstanding Option Shares. Should the Optionee’s Service terminate by reason of his
Retirement prior to December 31, 2014, then the Optionee shall immediately vest in the additional number of Option Shares (if any) in which the Optionee would have been vested at the time of such termination had the Option Shares vested in a
series of thirty-six (36) successive equal monthly installments over the duration of a three (3) year vesting schedule commencing on the Vesting Commencement Date. 
 (b) This option, to the extent outstanding at the time of a Change in Control but not otherwise fully exercisable, shall automatically accelerate so that this option shall, immediately prior to the
effective date of such Change in Control, become exercisable for all of the Option Shares at the time subject to this option and may be exercised for any or all of those Option Shares as fully vested shares of Common Stock. However, this option
shall not become exercisable on such an accelerated basis, if and to the extent: (i) this option is to be assumed by the successor corporation (or parent thereof) or is otherwise to be continued in full


  
 5 








 
force and effect pursuant to the terms of the Change in Control transaction or (ii) this option is to be replaced with a cash retention program of the successor corporation which preserves
the spread existing at the time of the Change in Control on any Option Shares for which this option is not otherwise at that time exercisable (the excess of the Fair Market Value of those Option Shares over the aggregate Exercise Price payable for
such shares) and provides for subsequent payout of that spread in accordance with the same Vesting Schedule for those Option Shares as set forth in the Grant Notice. 
 (c) Immediately following the Change in Control, this option shall terminate and cease to be outstanding, except to the extent assumed by the Successor Corporation (or parent thereof) or otherwise
continued in effect pursuant to the terms of the Change in Control transaction. 
 (d) If this option is assumed in connection
with a Change in Control or otherwise continued in effect, then this option shall be appropriately adjusted, immediately after such Change in Control, to apply to the number and class of securities into which the shares of Common Stock subject to
this option would have been converted in consummation of such Change in Control had those shares actually been outstanding at the time. Appropriate adjustments shall also be made to the Exercise Price, provided the aggregate Exercise Price shall
remain the same. To the extent the actual holders of the Corporation’s outstanding Common Stock receive cash consideration for their Common Stock in consummation of the Change in Control, the successor corporation may, in connection with the
assumption or continuation of this option, substitute one or more shares of its own common stock with a fair market value equivalent to the cash consideration paid per share of Common Stock in such Change in Control, provided such common stock is
readily tradable on an established U.S. securities exchange or market. 
 (e) In the event the Optionee’s Service is
involuntarily terminated for reasons other than Misconduct within twenty-four (24) months following a Change in Control transaction which does not result in the accelerated vesting of this option pursuant to the provisions of subparagraph
(b) of this Paragraph 6, then the option (as assumed or continued in effect) shall automatically vest in full on an accelerated basis so that such option shall immediately become exercisable for all the Option Shares as fully-vested shares and
may be exercised for any or all of those Option Shares as vested shares. 
 (f) 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. 

7. Adjustment in Option Shares. In the event of any of the following transactions affecting the outstanding 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 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 (i) the total number and/or class of securities subject to this option and (ii) the Exercise Price 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.

 8. Stockholder Rights. The holder of this option shall not have any stockholder
rights with respect to the Option Shares until such person shall have exercised the option, paid the Exercise Price and become a holder of record of the purchased shares. 
 9. Manner of Exercising Option. 
 (a) In order to exercise this option
with respect to all or any part of the Option Shares for which this option is at the time exercisable, Optionee (or any other person or persons exercising the option) must take the following actions: 

(i) Execute and deliver to the Corporation a Notice of Exercise for the Option Shares for which the option is exercised or comply with
such other procedures as the Corporation may establish for notifying the Corporation of the exercise of this option for one or more Option Shares. 
 (ii) Pay the aggregate Exercise Price for the purchased shares in one or more of the following forms: 
 (A) cash or check made payable to the Corporation; 
 (B) shares of Common Stock
valued at Fair Market Value on the Exercise Date and held by Optionee (or any other person or persons exercising the option) for any required period necessary to avoid a charge to the Corporation’s earnings for financial reporting purposes; or

 (C) through a special sale and remittance procedure pursuant to which Optionee (or any other person or persons exercising
the option) shall concurrently provide irrevocable instructions (i) to a brokerage firm (reasonably satisfactory to the Corporation for purposes of administering such procedure in accordance with the Corporation’s
pre-clearance/pre-notification policies) to effect the immediate sale of the purchased shares and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate Exercise Price payable for
the purchased shares plus all applicable income and employment taxes required to be withheld by the Corporation by reason of such exercise and (ii) to the Corporation to deliver the certificates (which may be in electronic form) for the
purchased shares directly to such brokerage firm on such settlement date in order to complete the sale. 
 Except to the extent
the sale and remittance procedure is utilized in connection with the option exercise, payment of the Exercise Price must accompany the Notice of Exercise (or other notification procedure) delivered to the Corporation in connection with the option
exercise. 
 (iii) Furnish to the Corporation appropriate documentation that the person or persons exercising the option (if
other than Optionee) have the right to exercise this option. 
 (iv) Make appropriate arrangements with the Corporation (or
Parent or Subsidiary employing or retaining Optionee) for the satisfaction of all applicable income and employment tax withholding requirements applicable to the option exercise. 

  
 7 








 (b) As soon as practical after the Exercise Date, the Corporation shall issue to or on
behalf of Optionee (or any other person or persons exercising this option) a certificate (which may be in electronic form) for the purchased Option Shares, with the appropriate legends affixed thereto. 

(c) In no event may this option be exercised for any fractional shares. 

10. Compliance with Laws and Regulations. 
 (a) The exercise of this option and the issuance of the Option Shares upon such exercise shall be subject to compliance by the Corporation and Optionee 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 exercise and issuance. 
 (b) The inability of the Corporation to obtain approval from any regulatory body having authority deemed by the Corporation to be necessary to the lawful issuance and sale of any Common Stock pursuant to
this option shall relieve the Corporation of any liability with respect to the non-issuance or sale of the Common Stock as to which such approval shall not have been obtained. The Corporation, however, shall use commercially reasonable efforts to
obtain all such approvals. 
 11. Additional Conditions. 

(a) The Corporation may cancel this option, and the Optionee shall thereupon cease to have any further right to acquire any shares of
Common Stock under such cancelled option, at any time the Optionee is not in compliance with this Agreement, the Plan and the following conditions: 
 (i) Participant shall not render services for any organization or engage, directly or indirectly, in any business which, in the judgment of the Plan Administrator or, if delegated by the Plan
Administrator to the Chief Executive Officer, in the judgment of such officer, is or becomes competitive with the Corporation or any Affiliate, or which is or becomes otherwise prejudicial to or in conflict with the interests of the Corporation or
any Affiliate. Such judgment shall be based on Participant’s positions and responsibilities while employed by the Corporation or an Affiliate, Participant’s post-Service responsibilities and position with the other organization or
business, the extent of past, current and potential competition or conflict between the Corporation or an Affiliate and the other organization or business, the effect on customers, suppliers and competitors of Participant’s assuming the
post-Service position and such other considerations as are deemed relevant given the applicable facts and circumstances. Participant shall be free, however, to purchase as an investment or otherwise, stock or other securities of such organization or
business so long as they are listed upon a recognized securities exchange or traded over the counter, and such investment does not represent a substantial investment to Participant or a greater than one percent (1%) equity interest in the
organization or business. 
 (ii) Participant shall not, without prior written authorization from the Corporation, disclose to
anyone outside the Corporation, or use in other than the Corporation’s business, any secret or confidential information, knowledge or data, relating to the 

  
 8 








 
business of the Corporation or an Affiliate in violation of his agreement with the Corporation or the Affiliate. 
 (iii) Participant shall disclose promptly and assign to the Corporation or the Affiliate all right, title and interest in any invention or idea, patentable or not, made or conceived by Participant during
employment by the Corporation or the Affiliate, relating in any manner to the actual or anticipated business, research or development work of the Corporation or the Affiliate and shall do anything reasonably necessary to enable the Corporation or
the Affiliate to secure a patent where appropriate in the United States and in foreign countries. 
 (iv) Participant shall not
in any way, directly or indirectly (a) induce or attempt to induce any employee of the Corporation to quit employment with the Corporation; (b) otherwise interfere with or disrupt the Corporation’s relationship with its employees;
(c) solicit, entice, or hire away any employee of the Corporation; or (d) hire or engage any employee of the Corporation or any former employee of the Corporation whose employment with the Corporation ceased less than one (1) year
before the date of such hiring or engagement. 
 (v) Participant will not divert or attempt to divert from the Corporation any
business the Corporation had enjoyed or solicited from its customers during the two (2) years prior to the diversion or attempted diversion of such business. 
 (vi) Participant shall not violate any covenants contained in the Employment Agreement between the Participant and the Corporation, effective January 1, 2013. 

(b) Notwithstanding any other provision of the Plan or this Agreement, the Plan Administrator in its sole discretion may cancel this
option at any time prior to the exercise thereof, if the employment of the Optionee shall be terminated, other than by reason of death, unless the conditions in this Section 11 are met. 

(c) Failure to comply with the conditions of this Section 11 prior to, or during the six months after, any exercise of this option
shall cause the exercise to be rescinded. The Corporation shall notify the Optionee in writing of any such rescission within two (2) years after such exercise and within ten (10) days after receiving such notice, the Optionee shall pay to
the Corporation the amount of any gain realized or payment received as a result of the exercise rescinded. Such payment shall be made either in cash or by returning to the Corporation the number of shares that the Optionee received in connection
with the rescinded exercise. 
 (d) Upon exercise of this option, the Plan Administrator may require the Optionee to certify on
a form acceptable to the Plan Administrator, that the Optionee is in compliance with the terms and conditions of the Plan and this Agreement. 
 (e) This option, and the right to receive and retain any Option Shares or cash payments covered by this option, shall be subject to rescission, cancellation or recoupment, in whole or part, if and to the
extent so provided under any “clawback” or similar policy of the Corporation in effect on the Grant Date or that may be established thereafter, including any modification or amendment thereto, or as required by the Sarbanes-Oxley Act of


  
 9 








 
2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or other applicable law. 
 12. Successors and Assigns. Except to the extent otherwise provided in Paragraphs 3 and 6, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Corporation and
its successors and assigns and Optionee, Optionee’s assigns, the legal representatives, heirs and legatees of Optionee’s estate and any beneficiaries of this option designated by Optionee. 

13. 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. Any notice required to be given or delivered to Optionee shall be in writing and addressed to Optionee at the address
indicated below Optionee’s signature line on the Grant Notice. All notices shall be deemed effective upon personal delivery or upon deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified. 

14. Construction. This Agreement and the option 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 this option.

 15. 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. 
 16. Excess Shares. If
the Option Shares covered by this Agreement exceed, as of the Grant Date, the number of shares of Common Stock which may without stockholder approval be issued under the Plan, then this option shall be void with respect to those excess shares,
unless stockholder approval of an amendment sufficiently increasing the number of shares of Common Stock issuable under the Plan is obtained in accordance with the provisions of the Plan. In no event shall the Option be exercisable with respect to
any of the excess Option Shares unless and until such stockholder approval is obtained. 
 17. Additional Terms Applicable to
an Incentive Option. In the event this option is designated an Incentive Option in the Grant Notice, the following terms and conditions shall also apply to the grant: 
 (a) This option shall cease to qualify for favorable tax treatment as an Incentive Option if (and to the extent) this option is exercised for one or more Option Shares: (A) more than three
(3) months after the date Optionee ceases to be an Employee for any reason other than death or Permanent Disability or (B) more than twelve (12) months after the date Optionee ceases to be an Employee by reason of Permanent
Disability. 
 (b) No installment under this option shall qualify for favorable tax treatment as an Incentive Option if (and to
the extent) the aggregate Fair Market Value (determined at the Grant Date) of the Common Stock for which such installment first becomes exercisable hereunder would, when added to the aggregate value (determined as of the respective date or dates of
grant) of the Common Stock or other securities for which this option 

  
 10 









 
or any other Incentive Options granted to Optionee prior to the Grant Date (whether under the Plan or any other option plan of the Corporation or any Parent or Subsidiary) first become
exercisable during the same calendar year, exceed One Hundred Thousand Dollars ($100,000) in the aggregate. Should such One Hundred Thousand Dollar ($100,000) limitation be exceeded in any calendar year, this option shall nevertheless become
exercisable for the excess shares in such calendar year as a Non-Statutory Option. 
 (c) Should the exercisability of this
option be accelerated upon a Change in Control, then this option shall qualify for favorable tax treatment as an Incentive Option only to the extent the aggregate Fair Market Value (determined at the Grant Date) of the Common Stock for which this
option first becomes exercisable in the calendar year in which the Change in Control transaction occurs does not, when added to the aggregate value (determined as of the respective date or dates of grant) of the Common Stock or other securities for
which this option or one or more other Incentive Options granted to Optionee prior to the Grant Date (whether under the Plan or any other option plan of the Corporation or any Parent or Subsidiary) first become exercisable during the same calendar
year, exceed One Hundred Thousand Dollars ($100,000) in the aggregate. Should the applicable One Hundred Thousand Dollar ($100,000) limitation be exceeded in the calendar year of such Change in Control, the option may nevertheless be exercised for
the excess shares in such calendar year as a Non-Statutory Option. 
 (d) Should Optionee hold, in addition to this option, one
or more other options to purchase Common Stock which become exercisable for the first time in the same calendar year as this option, then for purposes of the foregoing limitations on the exercisability of such options as Incentive Options, this
option and each of those other options shall be deemed to become first exercisable in that calendar year, on the basis of the chronological order in which such options were granted, except to the extent otherwise provided under applicable law or
regulation.
