Period. Such Performance Share Units are referred to as “Earned Shares”. The Compensation Committee shall have the authority to exercise its discretion to reduce or increase the level of deemed achievement of the Performance Measures;
provided, that, in respect of any Performance Share Unit Award granted to any Participant who is, or is determined by the Compensation Committee to be likely to become, a “covered employee” within the meaning of Section 162(m) of the
Code (or any successor provision), only “negative discretion” (as such term is used in Treasury Regulation section 1.162-27(e)(2)(iii) or any successor provision) may be exercised if such adjustment would result in the loss of an otherwise
available deduction. 
 (ii) Performance levels.

performance below which the number of Performance Share Units actually covered by the Target Award shall be adjusted downward to zero.

Performance, the number of Earned Shares shall be interpolated on a straight-line basis between Threshold Performance and Target Performance amounts;

between Target Performance and Maximum Performance amounts;

above the Maximum Performance, the number of Earned Shares shall be 200% of the number of Performance Share Units granted under the Target Award. 
 3.5 Vesting and Forfeiture. To the extent not sooner vested or forfeited, Earned Shares shall vest on March 30, 2013. Any and all Performance Share Units that are not Earned Shares as of March 30, 2013 shall not vest and

 4.1 Forfeiture. Participant’s rights, payments, gains and
benefits with respect to an Award shall be subject to, in the sole and good faith judgment of the Compensation Committee or the Board, reduction, cancellation, forfeiture or recoupment upon termination of employment for cause, violation of material

 (b) all unvested Restricted Stock Unit Awards shall cease to vest and shall be forfeited; 
 (c) as to Performance Share Unit Awards, Participant shall be entitled to receive either (I) if no Change in Control occurs during the Performance Period, a pro-rata portion of the number of Performance Share Units that would have

the Performance Period) or (II) if a Change in Control occurs during the Performance Period and after Participant’s termination of employment with the Company, a pro-rata portion of the number of Performance Share Units granted under the Target
Award computed based on the ratio of the number of full months Participant is an employee of the Company during the Performance Period over 36 (the total number of months in the Performance Period), in each case, such Earned Shares to be deliverable

an employee. 
 (iv) For an illustration of these provisions under Section 5.2, see Exhibit B.

vesting and exercise, Shares purchased upon exercise of Options shall be promptly (but in any event within 3 business days), and upon vesting, Shares represented by vested Restricted Stock Unit Awards and vested Earned Shares shall be promptly (but
in any event within 30 days following vesting), be delivered to Participant by deposit in Participant’s Account, in book entry form, by direct registration with GrafTech’s transfer agent, or by delivery of a stock certificate; provided,
that, in connection with any transaction that constitutes or would, upon occurrence, constitute a Change in Control, GrafTech shall make delivery so that Participant shall have the ability to participate therein as the owner of the Shares so to be

 5.4 Transferability. 
 (i) Awards shall not be Transferable except by will or by the laws of descent and distribution.

 (ii) Shares delivered to Participant pursuant to this Agreement become non-forfeitable and transferable at the time they vest; provided, that

procedures. 
  

 6 

 5.5 Withholding Taxes. 
 (i) The Company shall withhold or deduct from any or all payments or amounts due to or held for Participant, whether due from the Company or held in Participant’s Account, an amount (the
“Withholding Amount”) equal to all taxes (including social security, unemployment, Medicare, and other governmental charges of any kind) required to be withheld or deducted with respect to any and all taxable income and other amounts
attributable to Awards (the “Withholding Requirement”). Alternatively, Participant may elect to pay the Withholding Amount in cash upon such terms and conditions as are acceptable to the Company. 
 (ii) The Withholding Amount shall be determined by the Company. The timing of withholding or deduction shall be determined by the Company; provided,
however, that, if such taxes are required to be paid to a tax or other governmental authority before such withholding or deduction is made, then the Company shall pay such taxes when due as agent for Participant and shall be entitled to
reimbursement therefor from such payments or amounts, or otherwise. 
 (iii) Unless Participant has made or makes a timely election pursuant to
Section 83(b) of the Code or has paid the Withholding Amount in cash as provided above, Participant authorizes GrafTech and any broker designated by it to sell, on his or her behalf and for his or her account, such number of Shares otherwise
deliverable pursuant to an Award as GrafTech or the broker may deem appropriate to satisfy each Withholding Requirement or to reimburse the Company in respect thereof, so that the net proceeds from such sale equal or exceed the applicable
Withholding Amount, and to use the net proceeds to satisfy such Withholding Requirement (with any excess net proceeds to be paid to or deposited in an account of Participant). 
 (iv) If Participant has made or makes an election pursuant to Section 83(b) of the Code, he or she shall immediately file a copy thereof with the Company and upon demand by the Company make a cash
payment to the Company equal to any Withholding Amount in respect thereof. 
 (v) In connection with any sale of Shares pursuant to this
Section 5.5, Participant agrees that: (a) such sale may be aggregated with sales of Shares other securities granted to other participants under the Plan or other plans of the Company; (b) such aggregated sales may be made from time to
time in one or more installments at any time and over time as GrafTech or the broker may deem necessary or appropriate with a view toward avoidance or minimization of disruption of the market for the Common Stock, administrative convenience,
minimization of costs and expenses or other factors; and (c) the net proceeds from such aggregated sales and the sale prices of the Shares sold may be allocated among such Shares and other securities and Participant and such other participants
as GrafTech or the broker may deem reasonable. 
 (vi) Participant understands that: (a) different Withholding Requirements may arise at
different times based on time of delivery or vesting of Awards, tax elections or other factors; (b) different Withholding Requirements may be based on different values attributable to Awards at such times or otherwise based on applicable tax
laws, changes in the financial condition of the Company, changes in market or economic conditions or other factors; (c) it may not be practicable or permissible to sell Shares to satisfy each Withholding Requirement at the time due because of
rules and requirements of the broker or the Company, potential liability for short-swing profits, applicable laws, applicable rules of any securities exchange or market, or other factors; and (d) as a result, Shares may be sold at times and
values that differ

  

 7 

 
from those applicable to such Withholding Requirement and that such differences can result in gains or losses relative to those values and capital gains and losses for tax purposes in addition to
the taxes described in Section 5.5(i). 
 (vii) Participant hereby appoints the Corporate Director of Human Resources and each officer of
GrafTech to be Participant’s true and lawful attorney-in-fact, with full power of substitution and re-substitution, to take, cause to be taken and authorize the taking of any and all actions which any such attorney-in-fact may deem necessary,
appropriate, convenient or expedient to sell Shares issuable pursuant to the Awards to generate net proceeds to satisfy any and all Withholding Requirements and to use net proceeds in satisfaction thereof. This power of attorney shall not be
affected in any manner by reason of the execution, at any time, of other powers of attorney and shall not be affected by the subsequent death, disability or incompetence of Participant. This power of attorney is irrevocable and coupled with an
interest and shall remain in effect until all Withholding Requirements have been fully and unconditionally satisfied. 
 (viii) Participant
acknowledges and agrees that neither the Company nor the broker, nor any of their respective affiliates, control persons, directors, officers, employees, representatives or agents, shall have any liability or obligation for any losses, damages,
costs or expenses of any kind or under any theory arising out of or in connection with any action or omission under this Section 5.5 (including the determination of any Withholding Amount or the time when any Withholding Requirement is required
to be satisfied or any sale of or delay in selling or failure to sell or the price, terms or conditions of sale of any Shares), including any liability for any claim that Participant could have made more or lost less in connection therewith or for
any capital gain or loss due to the difference in time between the triggering of a Withholding Requirement and the resale of Shares in respect thereof or for violations of insider trading or other laws or for incurrence of liability for short-swing
profits under Section 16(b) of the Exchange Act, except to the extent that a court of competent jurisdiction determines by final and non-appealable judgment that any such losses, damages, costs or expenses resulted from actions taken or omitted
in bad faith or due to gross negligence or willful misconduct. References in this Section 5.5 to “selling” and correlative terms include all activities related thereto, including placement and execution of sell orders, selection of
brokers and dealers, delivery of Shares, receipt of proceeds and payment of fees and commissions. 
 (ix) The provisions hereof regarding sale
of Shares to satisfy Withholding Requirements are also intended to constitute a trading plan within the meaning of Rule 10b5-1 under the Securities Act. 
 5.6 Notices. Notices to GrafTech under this Agreement shall be addressed to GrafTech International Ltd., 12900 Snow Road, Parma, Ohio 44130, Attention: Corporate Director of Human Resources, with a
copy to GrafTech’s General Counsel at the same address. Notices to Participant shall be addressed to the most recent address provided by Participant to GrafTech. Either party may designate in writing another address for notices. 
 5.7 Internal Revenue Code Section 409A. To the extent there are any ambiguities in this Agreement or the Plan, any such ambiguities shall be
construed in a manner that complies with Code Section 409A. 
 5.8 Amendments and Conflicting Agreements. This Agreement may be
amended by a written instrument executed by the parties which specifically states that it is amending this Agreement or by a written instrument executed by GrafTech which so states if such amendment is not adverse to Participant or relates to
administrative matters. 
  

 8 

 5.9 Interpretation. Unless otherwise expressly specified herein, all determinations, consents,
elections and other decisions by the Company, the Board, the Compensation Committee or the broker may be made, withheld or delayed in its sole and absolute discretion. 
 5.10 Disclosure and Use of Information. By signing and returning this Agreement, and as a condition of the grant of Awards, Participant hereby expressly consents to the collection, use, and
transfer of personal data by the Company and by any agent of the Company (“Data Recipients”) for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. Participant understands that
Data Recipients are or may be located in his or her country of residence or elsewhere. Further, Participant understands that he or she may, at any time, oppose the processing and transfer of his or her personal data, review the data, request that
any necessary amendments be made to it, or withdraw his or her consent by notifying the Company in writing. Participant further understands that withdrawing consent may affect his or her ability to participate in the Plan. 
 5.11 Effect on Employment Rights. Nothing in this Agreement shall be construed to confer upon Participant the right to be employed by the Company or
to interfere in any way with the right and authority of the Company either to increase or decrease the compensation of Participant at any time, or to terminate any employment or other relationship between Participant and the Company at any time and
for any reason or no reason.

 EXHIBIT A 
 RESTRICTED ACTIVITIES 
 From the effective date of this Agreement and
continuing for a period of two (2) years following (a) voluntary termination of Participant’s employment with the Company or (b) involuntary termination of Participant’s employment with the Company for cause, violation of
material policies, breach of noncompetition, confidentiality or other restrictive covenants, or engagement in Detrimental Conduct, Participant agrees to the following: 
 (i) Participant shall not, without the Company’s prior written consent, directly or indirectly, either for himself or herself or on behalf of any other corporation, partnership, company, person,
group, or entity, engage in (a) the business of manufacturing, distributing, selling or providing carbon or graphite products, services, material or equipment of the kind or type which are the same as or similar to those manufactured,
distributed, sold or provided by the Company now or at any time while Participant is an employee of the Company, or (b) any other business in which the Company directly or indirectly engages now or at any time while Participant is an employee
of the Company. For purposes of this Exhibit A, Participant shall be deemed to “engage in business” if he or she, directly or indirectly, engages or invests in, owns, manages, operates, controls or participates in the ownership,
management, operation or control of, is employed by, associated or connected in any manner with, or renders services or advice to, any corporation, partnership, company, person, group or entity engaged in the activities identified above; provided,
however, that Participant may invest in the securities of any enterprise (but without otherwise participating in the activities of such enterprise) if (x) such securities are listed on any international, national or regional securities exchange
or market or have been registered under Section 12(g) of the Securities Exchange Act of 1934 and (y) Participant does not beneficially own (as defined under Rule 13d-3 promulgated under the Securities Exchange Act of 1934) in excess
of 5% of the outstanding equity thereof (provided, that Participant shall be deemed not to beneficially own any securities owned by a registered or unregistered investment company with more than $50 million under management). 
 (ii) The provisions set forth in Section 1(i) above shall apply only to the reasonable and limited geographic area consisting of
(a) any state, country, possession, or territory in which the Company directly or indirectly has offices, operations, or customers, or otherwise conducts business and (b) during Participant’s period of employment, any state, country,
possession, or territory in which the Company plans to conduct business. 
 (iii) Participant shall not, directly or indirectly,
call on, solicit or take away any of the customers or potential customers of the Company on whom Participant called or with whom Participant became acquainted or of which Participant learned during employment with the Company. 
 (iv) Participant shall not, directly or indirectly, solicit for employment any employee of the Company or encourage, induce, attempt to
induce, or assist another to induce or attempt to induce any employee of the Company to terminate his or her employment with the Company. 
 (v) Participant shall not interfere, in any manner, with the business, trade, goodwill, sources of supply, or customers of the Company. Participant shall refrain from making any statements or

  

 10 

 
comments of a defamatory or disparaging nature to any third party regarding the Company or any of the Company’s officers, directors, policies or products, other than to comply with any law
or court, regulatory or governmental investigatory order or request. 
 (vi) If a court of competent jurisdiction determines
that the length of time, geographic scope or other restrictions, or any portion thereof, set forth in this Exhibit A is overly restrictive and unenforceable, the court may reduce or modify the same to the maximum limitations permitted by law, and as
so reduced or modified, the restrictions herein shall remain in full force and effect. If a court of competent jurisdiction determines that any provision of this Exhibit A is invalid or against public policy, the remaining provisions shall not be
affected thereby and shall remain in full force and effect. 
 (vii) The business of the Company is international in scope and
that the restrictions imposed by this Agreement are legitimate, reasonable and necessary to protect the Company’s investment in its businesses and the goodwill thereof. The scope and duration of the restrictions contained herein are reasonable
in light of the time that Participant has been engaged in the business of the Company, Participant’s reputation in the markets for the Company, and Participant’s relationship with the suppliers and customers of the Company. The
restrictions contained herein are not burdensome to Participant in light of the grant of Awards hereunder. Moreover, Participant has other means available to him or her for the pursuit of his or her livelihood. Except as otherwise provided herein,
this Exhibit A shall survive termination of the Agreement. 
 (viii) In the event of any violation by Participant of the
provisions set forth in this Exhibit A, the Company will sustain serious, irreparable and substantial harm to its business, the extent of which will be difficult to determine and impossible to fully remedy by an action at law for money damages.
Accordingly, in the event of such violation or threatened violation by Participant, the Company shall be entitled to an injunction before trial by any court of competent jurisdiction as a matter of course, in addition to all such other legal and
