 Exhibit 10.6 
 (For Use In the U.S.) 
 APPENDIX A 

TERMS AND CONDITIONS OF PERFORMANCE UNITS 
 1. Award. The Company hereby awards to the Employee under the Plan as a separate incentive in connection with his or her employment, and not in lieu of any salary or other compensation for his or
her services, an award of [NUMBER A] Performance Units on the date hereof, subject to all of the terms and conditions in this Agreement and the Plan. 
 2. Vesting. To the extent that the Performance Goals are achieved and Shares are earned (which may range from zero to [MAX NUMBER]), as determined and certified by the Committee in its sole
discretion, then the earned Shares shall be paid following the end of the Performance Period no later than
December 15th immediately following the end of the
Performance Period (the “Settlement Date”) provided that Employee shall have been continuously employed by the Company or by one of its Affiliates from the Grant Date through the last day of the Performance Period (the “Employment
Requirement”). For the avoidance of doubt, in the event that the Employment Requirement is waived pursuant to Paragraph 3, 4 or 6, except as set forth in Paragraph 7, payout of the Performance Units shall continue to depend on the extent to
which the Performance Goals are achieved and Shares are earned, as determined and certified by the Committee in its sole discretion. 
 3. Retirement If Employee was eligible for Retirement (defined as 55 years or more of age with 10 or more years of service with the Company or its Affiliates, or age 65 or older) on the Grant Date
and has a Termination of Service due to Retirement on or prior to the last day of the Performance Period, Employee shall be treated for purposes of this Agreement as having been continuously employed by the Company or by one of its Affiliates
through the last day of the Performance Period; provided, however, that if the Employee’s Termination of Service due to the Employee’s Retirement occurs within one (1) year following the Grant Date, then the threshold, target and
maximum number of Performance Units subject to this Agreement (and potential payouts in between) shall be adjusted proportionally by the time during such one (1) year period that the Employee remained an employee of the Company (based upon a
365 day year). For example, if the Employee is granted a target number of Performance Units equal to 6,000 and the Employee Terminated Service due to the Employee’s Retirement 30 days after the Grant Date, then the Employee’s target
number of Performance Units would be reduced from 6,000 shares to 493 shares (6,000 x 30/365) and the balance of the Performance Units would be cancelled. For the avoidance of doubt, except as set forth in Paragraph 7, the actual number of
Shares earned with respect to such adjusted number of Performance Units shall continue to depend on the extent to which the Performance Goals are achieved and Shares are earned, as determined and certified by the Committee in its sole discretion.

 If Employee was not eligible for Retirement (defined as 55 years or more of age with 10 or more years of service with
the Company or its Affiliates, or age 65 or older) on the Grant Date and has a Termination of Service due to Retirement on or prior to the last day of the Performance Period, Employee shall be treated for purposes of this Agreement as having been
continuously employed by the Company or by one of its Affiliates through the last day of the Performance Period; provided, however, that the threshold, target and maximum number of Performance Units subject to this Agreement (and potential payouts
in between) shall be adjusted proportionally by the time during the three (3) year Performance Period that the Employee remained an employee of the Company (based upon a 365 day year). For example, if the Employee is granted a target
number of Performance Units equal to 6,000 and the Employee Terminated Service due to the Employee’s Retirement 30 days after the Grant Date, then the 

  
 A-1

 
Employee’s target number of Performance Units would be reduced from 6,000 shares to 164 shares (6,000 x 30/1,095) and the balance of the Performance Units would be cancelled. For the
avoidance of doubt, except as set forth in Paragraph 7, the actual number of Shares earned with respect to such adjusted number of Performance Units shall continue to depend on the extent to which the Performance Goals are achieved and Shares are
earned, as determined and certified by the Committee in its sole discretion. 
 4. Committee Discretion. The Committee,
in its absolute discretion, may waive the Employment Requirement with respect to all or any portion of the Performance Units at any time. 
 5. Forfeiture. Except as provided in Paragraphs 3, 4, 6 or 7(b) and notwithstanding any contrary provision of this Agreement, in the event that Employee ceases to be continuously employed by the
Company or by one of its Affiliates through the last day of the Performance Period, the Performance Units shall thereupon be forfeited. 
 6. Death of Employee. In the event of the Employee’s death prior to Employee’s Termination of Service, Employee shall be treated for purposes of this Agreement as having been continuously
employed by the Company or by one of its Affiliates through the last day of the Performance Period. Any distribution or delivery to be made to the Employee under this Agreement shall, if the Employee is then deceased, be made to the Employee’s
designated beneficiary, or if either no beneficiary survives the Employee or the Committee does not permit beneficiary designations, to the administrator or executor of the Employee’s estate. Any designation of a beneficiary by the Employee
shall be effective only if such designation is made in a form and manner acceptable to the Committee. Any transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the
Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer. 
 7.
Change in Control. 
 (a) In the event of a Change in Control (defined below) in which the Performance Units are
assumed, the Performance Goals shall be deemed to be satisfied at target and the target number of Shares (as adjusted pursuant to Section 12 hereof) shall be paid to the Employee on the Settlement Date provided that Employee shall have been
continuously employed by the Company or by one of its Affiliates from the Grant Date through the last day of the original Performance Period (or shall have had an earlier Termination of Service due to Retirement or death or as described in the
second to last sentence of this Section 7(a)). In the event Employee shall have had an earlier Termination of Service due to Retirement, such target number of Shares shall be prorated in accordance with Paragraph 3 hereof. If Employee has
entered into a Change in Control Agreement (the “CIC Agreement”) with the Company on or prior to the date of the applicable Change in Control and the Employee’s employment terminates under the circumstances described in
Section 2(d) or 4(a) of the CIC Agreement, then Employee shall become vested in the target number of Shares (as adjusted pursuant to Section 12 hereof, if applicable) upon the Release Deadline (as defined in the CIC Agreement) provided
that Employee shall have executed and not revoked the Release (as defined in the CIC Agreement) by the Release Deadline and such Shares shall be paid to the Employee on the Settlement Date; provided, however, that if a Change in Control is not
consummated, Employee shall return to the Company any payments provided to the Employee in connection with an employment termination described in Section 2(d) of the CIC Agreement. In the event of any conflict between this Agreement and CIC
Agreement, this Agreement shall control. 

  
 A-2

 (b) Notwithstanding the foregoing or anything to the contrary set forth in the Plan or any
other agreement or arrangement, in the event that the Performance Units are not assumed in connection with a Change in Control, the Performance Goals shall be deemed satisfied at target and the target number of Shares shall be paid to the Employee
on the Settlement Date in the same form, and determined in accordance with the undiscounted value of, the consideration received by the holders of Shares in the Change in Control without the requirement that Employee shall have been continuously
employed by the Company or by one of its Affiliates from the Grant Date through the last day of the original Performance Period and without the requirement that any portion of such payment be subject to any escrow, earn-out or similar provision.

 For purposes of this Agreement, Change in Control shall mean the occurrence of any of the following: 

(i) Any individual or group constituting a “person”, as such term is used in Sections 13(d) and 14(d)(2) of the Securities
Exchange Act of 1934, as amended, (other than (A) the Company or any of its subsidiaries or (B) any trustee or other fiduciary holding securities under an employee benefit plan of the Company or of any of its subsidiaries), is or becomes
the beneficial owner, directly or indirectly, of securities of the Company representing thirty percent (30%) or more of the combined voting power of the Company’s outstanding securities then entitled ordinarily (and apart from rights
accruing under special circumstances) to vote for the election of directors; or 
 (ii) Continuing Directors (directors of the
Company in office on the date hereof and any successor to any such director who was nominated or selected by a majority of the Continuing Directors in office at the time of the director’s nomination or selection and who is not an
“affiliate” or “associate” (as defined in Regulation 12B under the Securities Exchange Act of 1934, as amended) of any person who is the beneficial owner, directly or indirectly, of securities representing ten percent
(10%) or more of the combined voting power of the Company’s outstanding securities then entitled ordinarily to vote for the election of directors) cease to constitute at least a majority of the Board; or 

(iii) there occurs a reorganization, merger, consolidation or other corporate transaction involving the Company (a
“Transaction”), in each case with respect to which the stockholders of the Company immediately prior to such Transaction do not, immediately after the Transaction, own more than 50% of the combined voting power of the Company or other
corporation resulting from such Transaction; or 
 (iv) all or substantially all of the assets of the Company are sold,
liquidated or distributed; 
 provided, however, that a “Change in Control” shall not be deemed to have occurred under this
Agreement if, prior to the occurrence of a specified event that would otherwise constitute a Change in Control hereunder, the disinterested Continuing Directors then in office, by a majority vote thereof, determine that the occurrence of such
specified event shall not be deemed to be a Change in Control with respect to Employee hereunder if the Change in Control results from actions or events in which Employee is a participant in a capacity other than solely as an officer, employee or
director of the Company.

 8. Settlement of Performance Units. 

(a) Status as a Creditor. Prior to settlement of any vested Performance Units, the Performance Units will represent an unfunded
and unsecured obligation of the Company, payable (if at all) only from the general assets of the Company. The Employee is an unsecured general creditor of the Company, and settlement of vested Performance Units is subject to the claims of the
Company’s creditors. 
 (b) Form and Timing of Settlement. Performance Units will automatically be settled in the
form of Shares on the Settlement Date to the extent earned in accordance with the terms hereof. Fractional Shares will not be issued with respect to Performance Units. Where a fractional Share would be owed to the Employee with respect to vested
Performance Units, a cash payment equivalent will be paid in place of any such fractional Share using the Fair Market Value on the relevant Settlement Date. 
 9. Tax Liability and Withholding. The Company or one if its Affiliates shall assess applicable tax liability and requirements in connection with the Employee’s participation in the Plan,
including, without limitation, tax liability associated with the grant or settlement of Performance Units or sale of the underlying Shares (the “Tax Liability”). These requirements may change from time to time as laws or interpretations
change. Regardless of the Company’s or the Affiliate’s actions in this regard, the Employee hereby acknowledges and agrees that the Tax Liability shall be the Employee’s responsibility and liability. The Employee acknowledges that the
Company’s obligation to issue or deliver Shares shall be subject to satisfaction of the Tax Liability. Unless otherwise determined by the Company, Tax Liability shall be satisfied by the Company’s withholding all or a portion of any Shares
that otherwise would be issued to the Employee upon settlement of the vested Performance Units; provided that amounts withheld shall not exceed the amount necessary to satisfy the Company’s tax withholding obligations (minimum tax withholding
obligations if necessary to avoid adverse accounting consequences). Such withheld Shares shall be valued based on the Fair Market Value as of the date the withholding obligations are satisfied. The Company or one if its Affiliates may, at their
discretion, use other methods to satisfy the Tax Liability. Furthermore, the Employee agrees to pay the Company or the Affiliate any Tax Liability that cannot be satisfied by the foregoing methods. 

10. Rights as Stockholder. Neither the Employee nor any person claiming under or through the Employee shall have any of the rights
or privileges of a stockholder of the Company in respect of any Performance Units (whether vested or unvested) unless and until such Performance Units are settled in Shares and certificates representing such Shares shall have been issued, recorded
on the records of the Company or its transfer agents or registrars, and delivered to the Employee. After such issuance, recordation and delivery, the Employee shall have all the rights of a stockholder of the Company with respect to voting such
Shares and receipt of dividends and distributions on such Shares. This Agreement does not provide for dividend equivalents. 

11. Acknowledgments. The Employee acknowledges and agrees to the following: 

 

	 	•	 	 The Plan is discretionary in nature and the Committee may amend, suspend, or terminate it at any time; 

 

	 	•	 	 The grant of the Performance Units is voluntary and occasional and does not create any contractual or other right to receive future grants of
Performance Units, or benefits in lieu of the Performance Units even if the Performance Units have been granted repeatedly in the past; 

  
 A-4

	 	•	 	 All determinations with respect to such future Performance Units, if any, including but not limited to, the times when the Performance Units
shall be granted or when the Performance Units shall vest, will be at the sole discretion of the Committee; 

  

	 	•	 	 The Employee’s participation in the Plan is voluntary; 

 

	 	•	 	 The value of the Performance Units is an extraordinary item of compensation, which is outside the scope of the Employee’s employment
contract (if any), except as may otherwise be explicitly provided in the Employee’s employment contract (if any); 

  

	 	•	 	 The Performance Units are not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculating
termination, severance, resignation, redundancy, end of service, or similar payments, or bonuses, long-service awards, pension or retirement benefits; 

  

	 	•	 	 The future value of the Shares is unknown and cannot be predicted with certainty; 

 

	 	•	 	 No claim or entitlement to compensation or damages arises from the termination of the Award or diminution in value of the Performance Units or
Shares, and the Employee irrevocably releases the Company and its Affiliates from any such claim that may arise; 

  

	 	•	 	 Neither the Plan nor the Performance Units shall be construed to create an employment relationship where any employment relationship did not otherwise
already exist; 

  

	 	•	 	 Nothing in this Agreement or the Plan shall confer upon the Employee any right to continue to be employed by the Company or any Affiliate or shall
interfere with or restrict in any way the rights of the Company or the Affiliate, which are hereby expressly reserved, to terminate the employment of the Employee under applicable law; 

 

	 	•	 	 The transfer of employment of the Employee between the Company and any one of its Affiliates (or between Affiliates) shall not be deemed a Termination
of Service; 

  

	 	•	 	 Nothing herein contained shall affect the Employee’s right to participate in and receive benefits under and in accordance with the then current
provisions of any pension, insurance or other employee welfare plan or program of the Company or any Affiliate. 

 12. Changes in Stock. In the event that as a result of a stock dividend, stock split, reclassification, recapitalization, combination of Shares or the adjustment in capital stock of the Company or
otherwise, or as a result of a merger, consolidation, spin-off or other reorganization, the Company’s common stock shall be increased, reduced or otherwise changed, the Performance Units shall, subject to Section 409A of the Code, be
properly adjusted. 
 13. Address for Notices. Any notice to be given to the Company under the terms of this Agreement
shall be addressed to the Company, in care of its Secretary, at 3100 Hansen Way, Palo Alto, California 94304, or at such other address as the Company may hereafter designate in writing. 

  
 A-5

 14. Restrictions on Transfer. Except as provided in Paragraph 6 above, this award and
the rights and privileges conferred hereby shall not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be subject to sale under execution, attachment or similar process. Upon any
attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this award, or of any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this award and the rights and
privileges conferred hereby immediately shall become null and void. Regardless of whether the transfer or issuance of the Shares to be issued pursuant to this Agreement has been registered under the Securities Act of 1933, as amended (the “1933
Act”) or has been registered or qualified under the securities laws of any state, the Company may impose additional restrictions upon the sale, pledge, or other transfer of the Shares (including the placement of appropriate legends on stock
certificates and the issuance of stop-transfer instructions to the Company’s transfer agent) if, in the judgment of the Company and the Company’s counsel, such restrictions are necessary in order to achieve compliance with the provisions
of the 1933 Act, the securities laws of any state, or any other law. Stock certificates evidencing the Shares issued pursuant to this Agreement, if any, may bear such restrictive legends as the Company and the Company’s counsel deem necessary
under applicable laws or pursuant to this Agreement. 
 15. Binding Agreement. Subject to the limitation on the
transferability of this award contained herein, this Agreement shall be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 

16. Conditions for Issuance of Certificates for Stock. The Shares deliverable to the Employee upon settlement of vested
Performance Units may be either previously authorized but unissued Shares or issued Shares which have been reacquired by the Company. The Company shall not be required to issue any certificate or certificates for Shares hereunder prior to
fulfillment of all the following conditions: (a) the admission of such Shares to listing on all stock exchanges on which such class of stock is then listed; (b) the completion of any registration or other qualification of such Shares under
any state or federal law or under the rulings or regulations of the Securities and Exchange Commission or any other governmental regulatory body, which the Committee shall, in its absolute discretion, deem necessary or advisable; (c) the
approval or other clearance from any state or federal governmental regulatory body, which the Committee shall, in its absolute discretion, determine to be necessary or advisable; and (d) the lapse of such reasonable period of time following the
Settlement Date as the Committee may establish from time to time for reasons of administrative convenience. 
 17. Plan
Governs. This Agreement is subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan, the provisions of the Plan shall govern. 

18. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California,
without reference to its principles of conflicts of law. 
 19. Committee Authority. The Committee shall have the power
to interpret the Plan and this Agreement, and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules. All actions taken and all interpretations and
determinations made by the Committee in good faith shall be final and binding upon the Employee, the Company and all other interested persons. No member of the Committee shall be personally liable for any action, determination or interpretation made
in good faith with respect to the Plan or this Agreement. In its absolute discretion, the Board may at any time and from time to time exercise any and all rights and duties of the Committee under the Plan and this Agreement.

 20. Captions. Captions provided herein are for convenience only and are not to serve
as a basis for interpretation or construction of this Agreement. 
 21. Severability. In the event that any provision in
this Agreement shall be held invalid or unenforceable, such provision shall be severable from, and such invalidity or unenforceability shall not be construed to have any effect on, the remaining provisions of this Agreement. 

22. Modifications to the Agreement. This Agreement constitutes the entire understanding of the parties on the subjects covered.
The Employee expressly warrants that he or she is not executing this Agreement in reliance on any promises, representations, or inducements other than those contained herein. Modifications to this Agreement or the Plan can be made only in an express
written contract executed by a duly authorized officer of the Company. 
 23. Amendment, Suspension or Termination of the
Plan. By accepting this award, the Employee expressly warrants that he or she has received a right to an equity based award under the Plan, and has received, read, and understood a description of the Plan. The Employee understands that the Plan
is discretionary in nature and may be modified, suspended, or terminated by the Company at any time. 
 24.
Authorization to Release and Transfer Necessary Personal Information. The Employee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of his or her personal data by and
among, as applicable, the Company and the Affiliates for the exclusive purpose of implementing, administering and managing the Employee’s participation in the Plan. The Employee understands that the Company and the Affiliates may hold certain
personal information about the Employee including, but not limited to, the Employee’s name, home address and telephone number, date of birth, social security number (or any other social or national identification number), salary, nationality,
job title, number of Shares held and the details of all Performance Units or any other entitlement to Shares awarded, cancelled, vested, unvested or outstanding for the purpose of implementing, administering and managing the Employee’s
participation in the Plan (the “Data”). The Employee understands that the Data may be transferred to the Company or any of the Affiliates, or to any third parties assisting in the implementation, administration and management of the Plan,
that these recipients may be located in the Employee’s country or elsewhere, and that the recipients’ country may have different data privacy laws and protections than the Employee’s country. The Employee understands that he or she
may request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. The Employee authorizes the recipients to receive, possess, use, retain and transfer the Data, in
electronic or other form, for the sole purpose of implementing, administering and managing his or her participation in the Plan, including any requisite transfer of such Data to a broker or other third party assisting with the administration of
Performance Units under the Plan or with whom Shares acquired pursuant to the Performance Units or cash from the sale of such Shares may be deposited. Furthermore, the Employee acknowledges and understands that the transfer of the Data to the
Company or the Affiliates or to any third parties is necessary for his or her participation in the Plan. The Employee understands that Data will be held only as long as is necessary to implement, administer and manage his or her participation in the
Plan. The Employee understands that he or she may, at any time, view the Data, request additional information about the storage and processing of the Data, require any necessary amendments to the Data or refuse or withdraw the consents herein by
contacting his or her local human resources representative in writing. The Employee further acknowledges that withdrawal 

  
 A-7

 
of consent may affect his or her ability to vest in or realize benefits from the Performance Units, and his or her ability to participate in the Plan. For more information on the consequences of
refusal to consent or withdrawal of consent, the Employee understands that he or she may contact his or her local human resources representative. 
 25. [Electronic Delivery: By executing this Agreement Employee consents to the electronic delivery of the Plan documents and this Agreement.]

 Exhibit 10.7 
 VARIAN MEDICAL SYSTEMS, INC. 
 Grant Agreement – Deferred Stock
Units 
 GRANT AGREEMENT made as of
                    , 20     (the “Grant Date”) between Varian Medical Systems, Inc., a Delaware corporation (the
“Company”), and                      (the “Director”). 
 1. Grant of Deferred Stock Deferred Stock Units. The Company hereby grants to the Director
                Deferred Stock Units. Each Deferred Stock Unit shall be deemed to be the equivalent of one Share. 

2. Subject to the Plan. The Agreement is subject to, and governed by, the provisions of the Varian Medical Systems, Inc.
Third Amended and Restated 2005 Omnibus Stock Plan (the “Plan”) and, unless the context requires otherwise, terms used herein shall have the same meaning as in the Plan. In the event of a conflict between the provisions of the Plan and
this Agreement, the Plan shall control. 
 3. Account. The Company shall credit to a bookkeeping account (the
“Account”) maintained by the Company for the Director’s benefit the Deferred Stock Units. On each date that cash dividends are paid on the Shares, the Company will credit the Account with a number of additional Deferred Stock Units
equal to the result of dividing (i) the product of the total number of Deferred Stock Units credited to the Account on the record date for such dividend and the per Share amount of such dividend by (ii) the Fair Market Value of one Share
on the date such dividend is paid by the Company to shareholders. The additional Deferred Stock Units shall be or become vested to the same extent as the Deferred Stock Units that resulted in the crediting of such additional Deferred Stock Units.

 4. Vesting. All of the Deferred Stock Units shall initially be unvested. During the 12-month period following
the Grant Date, 25% of the Deferred Stock Units shall become vested as of the end of each 3-month period following the Grant Date, provided the Director has continued on the Board until the end of such 3-month period. All of the Deferred
Stock Units credited to the Account shall become fully vested upon the occurrence of a Change in Control (as defined in Appendix A) or the Director’s death, provided the Director is then serving on the Board. 

5. Termination of Service. In the event of the Director’s Termination of Service, other than as a result of death,
Disability or Retirement, the Deferred Stock Units credited to the Account that were not vested on the date of such Termination of Service shall be immediately forfeited. In the event of the Director’s death, Disability or Retirement while
serving on the Board, all of the Deferred Stock Units credited to the Account shall become fully vested. For purposes of this Agreement, “Termination of Service” shall mean “separation from service” as that term is defined in
Section 409A of the Code and the applicable guidance issued by the Secretary of the Treasury thereunder. 

 6. Forfeiture upon Engaging in Detrimental Activities. If, at any time within
one (1) year after the Director’s Termination of Service for any reason, the Director engages in any activity in competition with any activity of the Company, or inimical, contrary or harmful to the interests of the Company, including, but
not limited to: (i) conduct related to the Director’s service on the Board for which either criminal or civil penalties against the Director may be sought, (ii) violation of the Company’s policies, or (iii) disclosure or
misuse of any confidential information or material concerning the Company, then (A) the Deferred Stock Units shall be forfeited effective as of the date on which the Director enters into such activity, and (B) the Director shall within ten
(10) days after written notice from the Company return to the Company the Shares paid by the Company to the Director with respect to the Deferred Stock Units and, if the Director has previously sold all or a portion of the Shares paid to the
Director by the Company, the Director shall pay the proceeds of such sale to the Company. 
 7. Payment of Deferred Stock
Units. The Company shall make a payment to the Director of the vested Deferred Stock Units credited to the Account as provided in Section 8 upon the earliest of (i) the Director’s Termination of Service for any reason,
(ii) the third anniversary of the Grant Date, (iii) a Change in Control, or (iv) the Director’s death (in accordance with the provisions of Section 9); provided that if payment is made pursuant to Section 7(i) and the
Director is deemed at the time of such Termination of Service to be a “specified” employee under Section 409A of the Code, then payment shall not be made or commence until the earliest of (i) the expiration of the six (6)-month
period measured from the date of Director’s Termination of Service; or (ii) the date of Director’s death following such Termination of Service; provided, however, that such deferral shall only be effected to the extent required to
avoid adverse tax treatment to Director, including (without limitation) the additional twenty percent (20%) tax for which Director would otherwise be liable under Section 409A(a)(1)(B) of the Code in the absence of such deferral.

 8. Form of Payment. Payments pursuant to Section 7 shall be made in Shares equal to the number of vested
Deferred Stock Units credited to the Account. Payment shall be made as soon as practicable after the applicable payment date, but in no event later than 30 days after the date established pursuant to Section 7. 

9. Beneficiary. In the event of the Director’s death prior to payment of the Deferred Stock Units credited to the
Account, payment shall be made to the last beneficiary designated in writing that is received by the Company prior to the Director’s death or, if no designated beneficiary survives the Director, such payment shall be made to the Director’s
estate. 
 10. Source of Payments. The Director’s right to receive payment under this Agreement shall be an
unfunded entitlement and shall be an unsecured claim against the general assets of the Company. The Director has only the status of a general unsecured creditor hereunder, and this Agreement constitutes only a promise by the Company to pay the value
of the Account on the payment date. 
 11. Nontransferability. Except as otherwise permitted under the Plan, this
Agreement shall not be assignable or transferable by the Director or by the Company (other than to successors of the Company) and no amounts payable under this Agreement, or any rights 

  
 - 2 -

 
therein, shall be subject in any manner to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, levy, lien, attachment, garnishment, debt or other charge or disposition
of any kind. 
 12. Notices. All notices required or permitted under this Agreement shall be in writing and

 APPENDIX A 
 “Change in Control” means and shall be deemed to have occurred as of the date of the first to occur of the following events: 

(a) Any Person or Group (other than a Person or Group who effectively controls the Company within the meaning of Treasury Regulation
Section 1.409A-3(i)(5)(vi)) acquires stock of the Company that, together with stock held by such Person or Group, constitutes more than 50% of the total fair market value or total voting power of the stock of the Company. However, if any Person
or Group is considered to own more than 50% of the total fair market value or total voting power of the stock of the Company, the acquisition of additional stock by the same Person or Group is not considered to cause a Change in Control. An increase
in the percentage of stock owned by any Person or Group as a result of a transaction in which the Company acquires its stock in exchange for property will be treated as an acquisition of stock for purposes of this subsection. This subsection applies
only when there is a transfer of stock of the Company (or issuance of stock of the Company) and stock in the Company remains outstanding after the transaction; 
 (b) Any Person or Group acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such Person or Group) ownership of stock of the Company possessing 35% or
more of the total voting power of the stock of the Company. However, if any Person or Group is considered to effectively control the Company within the meaning of Treasury Regulation Section 1.409A-3(i)(5)(vi), the acquisition of additional
stock by the same Person or Group is not considered to cause a Change in Control; 
 (c) A majority of members of the
Company’s Board is replaced during any 12-month period by Directors whose appointment or election is not endorsed by a majority of the members of the Company’s Board prior to the date of the appointment or election; or 

(d) Any Person or Group acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such
Person or Group) assets from the Company that have a total gross fair market value equal to or more than 40% of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions. For this
purpose, gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. However, no Change in Control shall be deemed to
occur under this subsection (d) as a result of a transfer to an entity that is controlled by the shareholders of the Company immediately after the transfer as follows: 

(i) A shareholder of the Company (immediately before the asset transfer) in exchange for or with respect to its stock;

 (ii) An entity, 50% or more of the total value or voting power of which is owned, directly or indirectly, by
the Company; 

 (iii) A Person or Group that owns, directly or indirectly, 50% or more of
the total value or voting power of all the outstanding stock of the Company; or 
 (iv) An entity, at least 50%
of the total value or voting power of which is owned, directly or indirectly, by a person described in clause (iii) above. 

For purposes of clauses (ii), (iii), and (iv) above, a Person’s or a Group’s status is determined immediately after the
transfer of assets. 
 For these purposes, the term “Person” shall mean an individual, Company, association, joint
stock company, business trust or other similar organization, partnership, limited liability company, joint venture, trust, unincorporated organization or government or agency, instrumentality or political subdivision thereof or any other person, in
each case, to the extent consistent with Treasury Regulation Section 1.409A-3(i)(5). The term “Group” shall have the meaning set forth in Treasury Regulation Section 1.409A-3(i)(5), or any successor thereto in effect at the time
a determination of whether a Change of Control has occurred is being made.
