Exhibit 10.4


 


EXECUTION VERSION


 


CHANGE IN CONTROL AGREEMENT


 


THIS CHANGE IN CONTROL AGREEMENT (this “Agreement”)
is entered into effective as of August 1, 2020, by and between VARIAN MEDICAL SYSTEMS, INC., a Delaware corporation (the “Company”)1,
and Christopher Toth, an employee of the Company or one of its subsidiaries (“Employee”).


 


The Company’s Board of Directors (the
“Board”) has determined that it is in the best interest of the Company and its stockholders for the Company to agree
to pay Employee termination compensation in the event Employee should leave the employ of the Company under the circumstances described
below. The Board recognizes that the possibility of a proposal from a third person, whether or not solicited by the Company, concerning
a possible “Change in Control” of the Company (as such language is defined in Section 3(c)) will be unsettling to Employee.
Therefore, the arrangements set forth in this Agreement are being made to help assure a continuing dedication by Employee to Employee’s
duties to the Company notwithstanding the proposal or occurrence of a Change in Control. The Board believes it imperative, should
the Company receive any proposal from a third party, that Employee, without being influenced by the uncertainties of Employee’s
own situation, be able to assess and advise the Board whether such proposals are in the best interest of the Company and its stockholders,
and to enable Employee to take action regarding such proposals as the Board might determine to be appropriate. The Board also wishes
to demonstrate to key personnel that the Company desires to enhance management relations and its ability to retain and, if needed,
to attract new management, and intends to ensure that loyal and dedicated management personnel are treated fairly.


 


In view of the foregoing, the Company and
Employee agree as follows:


 


		1.	EFFECTIVE DATE AND TERM OF AGREEMENT.



 


This Agreement is effective and binding
on the Company and Employee as of the date hereof; provided, however, that, subject to Section 2(d), the provisions of Sections
3 and 4 shall become operative only upon the Change in Control Date (as defined below).


 





 






1 “Company” shall
include the Company, any successor to the Company’s business and/or assets, and any party which executes and delivers the
agreement required by Section 6(e) or which otherwise becomes bound by the terms and conditions of this Agreement by operation
of law or otherwise.


 






     


     


    

 


		2.	EMPLOYMENT OF EMPLOYEE.



 


(a)       Except
as provided in Sections 2(b), 2(c) and 2(d), nothing in this Agreement shall affect any right which Employee may otherwise have
to terminate Employee’s employment, nor shall anything in this Agreement affect any right which the Company may have to terminate
Employee’s employment at any time in any lawful manner.


 


(b)       In
the event of a Potential Change in Control (as defined below), to be eligible to receive the benefits provided by this Agreement,
Employee will not voluntarily leave the employ of the Company, and will continue to perform Employee’s regular duties and
the services specified in the recitals of this Agreement until the Change in Control Date. Should Employee voluntarily terminate
employment prior to the Change in Control Date, this Agreement shall lapse upon such termination and be of no further force or
effect.


 


(c)       If
Employee’s employment terminates on or after the Change in Control Date as provided under Sections 3 and 4, the Company will
provide to Employee the payments and benefits as provided in Sections 3 and 4.


 


(d)       If
Employee’s employment is terminated by the Company without Cause within sixty (60) days prior to and including the Change
in Control Date but on or after a Potential Change in Control Date, subject to Section 4(d), then the Company will provide to Employee
the payments and benefits described in Sections 3 and 4 unless the Company reasonably demonstrates that Employee’s termination
of employment neither (i) was at the request of a third party who has taken steps reasonably calculated to effect a Change in Control
nor (ii) arose in connection with or in anticipation of a Change in Control. Such payments and benefits will be paid within five
(5) business days following the 60th day after Employee’s Separation from Service except that the stock option and restricted
stock acceleration benefits described in Section 4(a)(iii) shall be provided on the Change in Control Date and accelerated restricted
stock units outstanding on March 1, 2019, shall be settled on their originally scheduled vesting dates (with all other restricted
stock units settled within five (5) business days following the 60th day after the Employee’s Separation from Service). In
the event that a Change in Control is not consummated, Employee shall not be entitled to any payments or benefits on account of
Employee’s termination described in this Section 2(d).


 


		3.	TERMINATION FOLLOWING CHANGE IN CONTROL.



 


(a)       If
a Change in Control shall have occurred, Employee shall be entitled to the benefits provided in Section 4 upon the subsequent termination
of Employee’s employment within the applicable period set forth in Section 4 unless such termination (i) is due to Employee’s
death or Disability or is for Cause or (ii) is effected by Employee other than for Good Reason (as such terms are defined in Section
3(c)).


 






     


     


    

 


(b)       If
Employee’s employment shall be terminated by the Company for Cause or by Employee other than for Good Reason during the term
of this Agreement, the Company shall pay Employee’s base salary through the date of termination at the rate in effect at
the time notice of termination is given, and the Company shall have no further obligations to Employee under this Agreement.


 


(c)       For
purposes of this Agreement:


 


“Base Salary” shall mean the
annual base salary paid to Employee immediately prior to a Change in Control, provided that such amount shall in no event
be less than the annual base salary paid to Employee during the one (1) year period immediately prior to the Change in Control.

be deemed to have occurred if:


 


(i)       Any
individual or group constituting a “person”, as such term is used in Sections 13(d) and 14(d)(2) of the Exchange Act
(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 cease to constitute at least a majority of the Board; or

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.

in reasonable detail) and a reasonable opportunity to be heard and cure such failure are given to Employee by the Board or a committee
thereof; or


 


(ii)       The
willful commission by Employee of a wrongful act that caused or was reasonably likely to cause substantial damage to the Company,
or an act of fraud in the performance of Employee’s duties on behalf of the Company that caused or was reasonably likely
to cause substantial damage to the Company; or


 


(iii)       The
conviction of, or plea of nolo contendere by, Employee for commission of a felony in connection with the performance of
Employee’s duties on behalf of the Company; or

mean the 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 Exchange Act) 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.


 


“Disability” shall mean Employee’s
incapacity due to physical or mental illness such that Employee shall have become qualified to receive benefits under the Company’s
long-term disability plan as in effect on the date of the Change in Control.

action that results in a material diminution in the title, status (including reporting relationships), authority, duties, or responsibilities
of Employee when compared to the highest level of title, status (including reporting relationships), authority, duties or responsibilities,
respectively, applicable to Employee at any time during the six (6) month period prior to the Change in Control Date; or


 


(ii)       A
material reduction in any of Employee’s Base Salary, annual bonus opportunity, or annual long-term incentive award opportunity
(in each case, as the same may have been increased from time to time after the Change in Control Date) other than a reduction implemented
with the consent of Employee; or


 


(iii)       The
relocation of the office of the Company where Employee is providing Employee’s services to the Company immediately prior
to the Change in Control Date (the “CIC Location”) to a location which is more than 35 miles away from the CIC Location
or the Company’s requiring Employee to be based more than 35 miles away from the CIC Location (except for required travel
on the Company’s business to an extent substantially consistent with Employee’s customary business travel obligations
in the ordinary course of business prior to the Change in Control Date);


 


(iv)       The
failure of the Company to obtain promptly upon any Change in Control the express written assumption of an agreement to perform
this Agreement by any successor as contemplated in Section 6(e) unless such assumption occurs by operation of law; or


 


(v)       A
material breach of this Agreement by the Company or any successor.


 


Notwithstanding anything in this Agreement to the contrary,
a termination for “Good Reason" shall not occur unless the Employee has provided written notice to the Company of the
Employee's intention to terminate employment and the specific reason(s) for such “Good Reason”. Following receipt of
such written notice, the Company shall have the right, within fifteen (15) days of receiving such notice, to cure the circumstances
giving rise to such “Good Reason”.

described in which would result in a Change in Control, (b) the approval by the Board of a transaction or series of transactions,
the consummation of which would result in a Change in Control, or (c) the public announcement of a tender offer for the Company’s
voting stock, the completion of which would result in a Change in Control; provided, that no such event shall be a “Potential
Change in Control” unless (i) in the case of any agreement or letter of intent described in clause (a), the transaction described
therein is subsequently consummated by the Company and the other party or parties to such agreement or letter of intent and thereupon
constitutes a "Change in Control", (ii) in the case of any Board-approved transaction described in clause (b), the transaction
so approved is subsequently consummated and thereupon constitutes a "Change in Control" or (iii) in the case of any tender
offer described in clause (c), such tender offer is subsequently completed and such completion thereupon constitutes a "Change
in Control".


 






     


     


    

 


“Potential Change in Control Date”
shall mean the date on which a Potential Change in Control occurs.


 


“Separation from Service” shall
have the meaning set forth in Section 409A of the Code.


 


(d)       Any
termination of employment by the Company or by Employee shall be communicated by written notice, specify the date of termination,
state the specific basis for termination and set forth in reasonable detail the facts and circumstances of the termination in order
to provide a basis for determining the entitlement to any payments under this Agreement.


 


(e)       If
within thirty (30) days after notice of termination is given, the party to whom the notice was given notifies the other party that
a Dispute exists, the parties will promptly pursue resolution of such Dispute with reasonable diligence; provided, however,
that pending resolution of any such Dispute, the Company shall pay 75% of any amounts which would otherwise be due Employee pursuant
to Section 4 if such Dispute did not exist into escrow pending resolution of such Dispute and pay 25% of such amounts to Employee.
Employee agrees to return to the Company any such amounts to which it is ultimately determined that he is not entitled. If, following
a final, nonappealable determination that Employee is not entitled to retain all or any portion of this amount, Employee fails
to return such excess amount, then Employee shall be required to pay the full costs of recovering such amount. Any escrowed amounts
that are released shall otherwise be paid as required under this Agreement and, in no case, later than the end of the calendar
year in which the Company and Employee enter into a legally binding settlement of such dispute, the Company concedes the amount
is payable, or the Company is required to make such payment pursuant to a final and nonappealable judgment or other binding decision.


 


		4.	PAYMENTS AND BENEFITS UPON TERMINATION.



 


(a)       If
within twenty-four (24) months after a Change in Control, the Company terminates Employee’s employment other than by reason
of Employee’s death, Disability, or for Cause, or if Employee terminates Employee’s employment for Good Reason, then
the Employee shall be entitled to the following payments and benefits following Employee’s Separation from Service:


 


(i)       The
Company shall pay to Employee as compensation for services rendered, no later than five (5) business days following the Release
Deadline, a lump sum severance payment equal to two (2) multiplied by the sum of: (A) Employee’s Base Salary; and (B) the
greater of (x) the Employee's most recently established target annual bonus under the Company's annual bonus plan (or, if higher,
the Employee’s target annual bonus as of immediately prior to the Change in Control) or (y) the average annual bonus that
was paid to Employee in the three (3) fiscal years ending prior to the date of termination. Notwithstanding the foregoing, if Employee
has not completed at least three (3) full fiscal years of service with the Company prior to Employee’s termination date,
then the amount determined in (y) above, shall be based on the average annual bonus for the number of full fiscal years Employee
has completed.


 






     


     


    

 


(ii)       The
Company shall pay to Employee as compensation for services rendered, no later than five (5) business days following the Release
Deadline, a lump sum payment equal to a pro rata portion (based on the number of days elapsed during the fiscal year and/or other
bonus performance period in which the termination occurs) of Employee’s target bonus under the Company’s annual bonus
plan for the fiscal year in which the termination occurs (or, if higher, the Employee’s target annual bonus as of immediately
prior to the Change in Control) and under any other applicable Company bonus plan for any other partially completed bonus performance
period in which the termination occurs.


 


(iii)       All
waiting periods for the exercise of any stock options granted to Employee and all conditions or restrictions of any restricted
stock granted to Employee shall terminate, and all such awards shall be fully vested and, if applicable, exercisable in full according
to their terms. Any such awards that are subject to performance conditions shall fully vest (and, if applicable, be fully exercisable)
in each case with respect to the target number of shares covered by the applicable award. In addition, all restricted stock units
granted to Employee shall fully vest, and the stock underlying such units shall be transferred to Employee (x) except in the case
of a Separation from Service that occurs during the period between the 18-month and 24-month anniversaries of the Change in Control,
within five (5) business days following the Release Deadline with respect to awards granted after March 1, 2019 or (y) on the originally
scheduled vesting dates, in the case of (1) a Separation from Service that occurs during the period between the 18-month and 24-month
anniversaries of the Change in Control or (2) awards outstanding as of March 1, 2019. Any performance-based restricted stock units
held by Employee shall be governed by the terms of the applicable grant agreement. In the event that an award subject to performance
conditions is not assumed or substituted in connection with a Change in Control, and the plan or agreement under which the award
is granted provides for full vesting of such award in the event of such non-assumption or non-substitution, such awards will vest
with respect to the target number of shares covered by the applicable award.


 


(iv)       If
Employee properly elects and maintains COBRA coverage, the Company shall provide payment of Employee’s COBRA premiums for
up to eighteen (18) months in a method as determined by the Company that is exempt from Section 409A of the Code. This payment
may be taxable income to the Employee and subject to tax withholding.


 


(v)       Employee
may elect within 90 days after his or her Separation from Service to purchase any automobile then in the possession of Employee
and subject to a lease of which the Company is the lessor by payment to the Company of the residual value set forth in the lease,
without any increase for remaining lease payments during the term or other lease breakage costs.


 


(vi)       All
payments and benefits provided under this Agreement shall be subject to applicable tax withholding.


 






     


     


    

 


(b)       Following
Employee’s termination of employment for any reason, the Company shall have the unconditional right to reduce any payments
owed to Employee hereunder by the amount of any due and unpaid principal and interest on any loans by the Company to Employee and
Employee hereby agrees and consents to such right on the part of the Company. Any loan offset made under this Section 4(b) shall
be made at the same time the payments reduced hereunder would have otherwise been made and otherwise in a manner that would not
result in the imposition of taxes to Employee under Section 409A of the Code. If it is not possible to make such offset without
the imposition of taxes to Employee under Section 409A of the Code, such offset shall not be made.


 


(c)       In
the event this Agreement or any compensation or benefit paid to Employee hereunder is deemed to be subject to Section 409A of the
Code, Employee and the Company agree to negotiate in good faith to adopt such amendments that are necessary to comply with Section
409A of the Code or to exempt such compensation or benefits from Section 409A. In addition, to the extent (i) any compensation
or benefits to which Employee becomes entitled under this agreement, or any agreement or plan referenced herein, in connection
with Employee's termination of employment with the Company constitute deferred compensation subject to Section 409A of the Code
and (ii) Employee is deemed at the time of such termination of employment to be a “specified” employee under Section
409A of the Code, then such compensation or benefits shall not be made or commence until the earliest of (i) the expiration of
the six (6)-month period measured from the date of Employee's “separation from service” (as such term is at the time
defined in Treasury Regulations under Section 409A of the Code) with the Company; or (ii) the date of Employee's death following
such separation from service; provided, however, that such deferral shall only be effected to the extent required
to avoid adverse tax treatment to Employee, including (without limitation) the additional twenty percent (20%) tax for which Employee
would otherwise be liable under Section 409A(a)(1)(B) of the Code in the absence of such deferral. During any period compensation
or benefits to Employee are deferred pursuant to the foregoing, Employee shall be entitled to interest on such deferral at a per
annum rate equal to the highest rate of interest applicable to six (6)-month money market accounts offered by the following institutions:
Citibank N.A., Wells Fargo Bank, N.A. or Bank of America, on the date of such “separation from service.” Upon the expiration
of the applicable deferral period, any compensation or benefits which would have otherwise been paid during that period (whether
in a single sum or in installments) in the absence of this paragraph shall be paid to Employee or Employee's beneficiary in one
lump sum.


 






     


     


    

 


(d)       Any
payment pursuant to this Section 4 shall be conditioned upon the Employee signing and not revoking a release in the form attached
as Exhibit A (the “Release”) not later than 60 days after the Employee’s Separation from Service (such
60th day, the “Release Deadline”). The Employee shall not be entitled to such payment, and no payment shall be made
to the Employee, until after the Release Deadline and subject to the Release having become effective on or prior to the Release
Deadline. The Company shall furnish such Release to the Employee in connection with the Employee’s Separation from Service.
If the Employee has signed the Release prior to the time the Company so furnishes such Release to the Employee, the Employee will
be required to again sign and not revoke the Release in connection with the Employee’s Separation from Service in order to
receive payments hereunder (as described above), and the prior signed Release shall be null and void.


 


		5.	TAX REIMBURSEMENT.



 


(a)         
Except as set forth below, in the event it shall be determined that any Payment (as defined below) would be subject to the
Excise Tax (as defined below), then the Employee shall be entitled to receive from the Company an additional payment (the “Gross-Up
Payment”) in an amount such that after payment by the Employee of all taxes (including any interest or penalties imposed
with respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect
thereto) and Excise Tax imposed upon the Gross-Up Payment, the Employee retains an amount of the Gross-Up Payment equal to the
Excise Tax imposed upon the Payments. Notwithstanding the foregoing provisions of this Section 5(a), if it shall be determined
that the Employee is entitled to the Gross-Up Payment, but that the Parachute Value (as defined below) of all Payments does not
exceed 110% of the Safe Harbor Amount (as defined below), then no Gross-Up Payment shall be made to the Employee and the amounts
payable under this Agreement shall be reduced so that the Parachute Value of all Payments, in the aggregate, equals the Safe Harbor
Amount. The reduction of the amounts payable hereunder, if applicable, shall be made by reducing the payments and benefits in the
following order: (i) cash payments that may not be valued under Treas. Reg. § 1.280G-1, Q&A-24(c) (“24(c)”),
(ii) equity-based payments that may not be valued under 24(c), (iii) cash payments that may be valued under 24(c), (iv) equity-based
payments that may be valued under 24(c) and (v) other types of benefits. With respect to each category of the foregoing, such reduction
shall occur first with respect to amounts that are not “deferred compensation” within the meaning of Section 409A of
the Code and next with respect to payments that are deferred compensation, in each case, beginning with payments or benefits that
are to be paid the latest in time. For purposes of reducing the Payments to the Safe Harbor Amount, only amounts payable under
this Agreement (and no other Payments) shall be reduced. If the reduction of the amounts payable under this Agreement would not
result in a reduction of the Parachute Value of all Payments to the Safe Harbor Amount, no amounts payable under this Agreement
shall be reduced pursuant to this Section 5(a) and the Employee shall be entitled to the Gross-Up Payment. The Company’s
obligation to make Gross-Up Payments under this Section 5 shall not be conditioned upon the Employee’s termination of employment.


 






     


     


    

 


(b)         
Subject to the provisions of Section 5(c), all determinations required to be made under this Section 5, including whether
and when a Gross-Up Payment is required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving
at such determination, shall be made by the Accounting Firm (as defined below). The Accounting Firm shall provide detailed supporting
calculations both to the Company and the Employee within 15 business days of the receipt of notice from the Employee that there
has been a Payment, or such earlier time as is requested by the Company. In the event that the Accounting Firm is serving as accountant
or auditor for the individual, entity or group effecting the Change in Control, the Employee may appoint another nationally recognized
accounting firm to make the determinations required under this Section 5 (which accounting firm shall then constitute the Accounting
Firm under this Section 5). All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any determination
by the Accounting Firm shall be binding upon the Company and the Employee. As a result of the uncertainty in the application of
Section 4999 of the Code , it is possible that Gross-Up Payments that will not have been made by the Company should have been made
(the “Underpayment”). In the event that the Company exhausts its remedies pursuant to Section 5(c) and the Employee
thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment
that has occurred and any such Underpayment shall be promptly paid by the Company to or for the Employee’s benefit.


 


(c)         
The Employee shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would
require the payment by the Company of the Gross-Up Payment. Such notification shall be given as soon as practicable but no later
than ten business days after the Employee is informed in writing of such claim. The Employee shall apprise the Company of the nature
of such claim and the date on which such claim is requested to be paid. The Employee shall not pay such claim prior to the expiration
of the 30-day period following the date on which the Employee gives such notice to the Company (or such shorter period ending on
the date that any payment of taxes with respect to such claim is due). If the Company notifies the Employee in writing prior to
the expiration of such period that the Company desires to contest such claim, the Employee shall:


 


(i)           
give the Company any information reasonably requested by the Company relating to such claim,


 


(ii)         
take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to
time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected
by the Company,


 






     


     


    

 


(iii)        
cooperate with the Company in good faith in order effectively to contest such claim, and


 


(iv)        
permit the Company to participate in any proceedings relating to such claim;


 


provided, however,
that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Employee harmless, on an after-tax basis, for any Excise Tax or income tax (including
interest and penalties) imposed as a result of such representation and payment of costs and expenses. Without limitation on the
foregoing provisions of this Section 5(c), the Company shall control all proceedings taken in connection with such contest and,
at its sole discretion, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the
applicable taxing authority in respect of such claim and may, at its sole discretion, either (x) pay the tax claimed to the appropriate
taxing authority on the Employee’s behalf and direct the Employee to sue for a refund or (y) contest the claim in any permissible
manner, and the Employee agrees to prosecute such contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company
pays such claim and directs the Employee to sue for a refund, the Company shall indemnify and hold the Employee harmless, on an
after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect
to such payment or with respect to any imputed income in connection with such payment; and further provided that any extension
of the statute of limitations relating to payment of taxes for the Employee’s taxable year with respect to which such contested
amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company’s control of the contest
shall be limited to issues with respect to which the Gross-Up Payment would be payable hereunder and the Employee shall be entitled
to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.


 


(d)         
If, after the Employee’s receipt of a Gross-Up Payment or payment by the Company of an amount on the Employee’s
behalf pursuant to Section 5(c), the Employee becomes entitled to receive any refund with respect to the Excise Tax to which such
Gross-Up Payment relates or with respect to such claim, the Employee shall (subject to the Company’s complying with the requirements
of Section 5(c) to the extent applicable) promptly pay to the Company the amount of such refund (together with any interest paid
or credited thereon after taxes applicable thereto). If, after payment by the Company of an amount on the Employee’s behalf
pursuant to Section 5(c), a determination is made that the Employee shall not be entitled to any refund with respect to such claim
and the Company does not notify the Employee in writing of its intent to contest such denial of refund prior to the expiration
of 30 days after such determination, then the amount of such payment shall offset, to the extent thereof, the amount of any Gross-Up
Payment required to be paid.


 






     


     


    

 


(e)         
Any Gross-Up Payment, as determined pursuant to this Section 5, shall be paid by the Company to the Employee within five
days of the receipt of the Accounting Firm’s determination; provided that, the Gross-Up Payment shall in all events be paid
no later than the end of the Employee’s taxable year next following the Employee’s taxable year in which the Excise
Tax (and any income or other related taxes or interest or penalties thereon) on a Payment are remitted to the Internal Revenue
Service or any other applicable taxing authority or, in the case of amounts relating to a claim described in Section 5(c) that
does not result in the remittance of any federal, state, local and foreign income, excise, social security and other taxes, the
calendar year in which the claim is finally settled or otherwise resolved. Notwithstanding any other provision of this Section
5, the Company may, in its sole discretion, withhold and pay over to the Internal Revenue Service or any other applicable taxing
authority, for the Employee’s benefit, all or any portion of the Gross-Up Payment, and the Employee hereby consents to such
withholding.

GENERAL RELEASE


 


This General Release of Claims (this “Agreement”)
is entered into on [●], 20[●], by and between a Varian Medical Systems, Inc. (“Varian” or the “Company”)

and all claims for violation of any federal, state, or municipal statute, including, but not limited to, Title VII of the
Civil Rights Act of 1964; the Civil Rights Act of 1991; the Rehabilitation Act of 1973; the Americans with Disabilities Act of
1990; the Fair Credit Reporting Act; the Age Discrimination in Employment Act of 1967 (the “ADEA”); the Older Workers

out of any dispute over the non-withholding or other tax treatment of any of the proceeds received by Employee as a result of this
Agreement; and any and all claims for attorneys’ fees and costs.


 


Employee enters into this Agreement on
Employee’s own behalf and on behalf of Employee’s heirs, beneficiaries, successors, representatives, trustees, administrators
and assigns. Employee represents that Employee has made no assignment or transfer of any right, claim, complaint, charge, duty,
obligation, demand, cause of action, or other matter waived or released by this General Release and Waiver of Claims section. Employee
agrees that the release set forth in this section shall be and will remain in effect in all respects a complete general release
as to the matters released. This release does not extend to any payments owed or obligations incurred under the CIC Agreement.


 






     


     


    

 


Nothing in this Agreement is intended to
waive claims (i) for unemployment or workers’ compensation benefits, (ii) for vested rights under the CIC Agreement and/or
employee benefit plans as applicable on the date Employee signs this Agreement, (iii) that may arise after Employee signs this
Agreement, (iv) for reimbursement of expenses under the Company’s expense reimbursement policies and California Labor Code
section 2802, (v) for rights, if any, to indemnification under any indemnification agreement between Employee and Varian (or any
of its affiliates) or under Varian’s or any affiliate’s certificate of incorporation or bylaws, including coverage
under applicable insurance policies such as director & officer insurance and comprehensive liability insurance that may apply
to Employee, each as amended or (vi) which cannot be released by private agreement.


 


Nothing in this Agreement (i) waives Employee’s
right to testify in an administrative, legislative, or judicial proceeding concerning alleged criminal conduct or alleged sexual
harassment on the part of the Company, or on the part of the agents or employees of the Company, when Employee has been required
or requested to attend such a proceeding pursuant to a court order, subpoena, or written request from an administrative agency
or the legislature, (ii) limits or affects Employee’s right to challenge the validity of this Agreement under the ADEA or
the OWBPA, (iii) prevents Employee from communicating with, filing a charge or complaint with or from participating in an investigation
or proceeding conducted by the Equal Employment Opportunity Commission, National Labor Relations Board, the Securities and Exchange
Commission, or any other any federal, state or local agency charged with the enforcement of any laws (each, a “Government
Agency”), including providing documents or any other information to any such Government Agency, (iv) limits or affects Employee’s
right to receive monetary rewards for providing information to any Government Agency under applicable whistleblower provisions,
or (v) limits Employee from exercising rights under Section 7 of the National Labor Relations Act to engage in protected, concerted
activity with other employees. By signing this Agreement, Employee is waiving rights to individual relief (including backpay, frontpay,
reinstatement or other legal or equitable relief) in any charge, complaint, or lawsuit or other proceeding brought by Employee
or on Employee’s behalf by any third party, except for any right Employee may have to receive a payment or award from a government
agency (and not the Company) for information provided to the government agency or otherwise where prohibited.


 


2.           
Release of Unknown Claims. Employee acknowledges that Employee is familiar with the provisions of California Code
Civil Section 1542, or comparable applicable state statute, which provides as follows:


 


A GENERAL RELEASE DOES NOT EXTEND TO
CLAIMS THAT THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE
RELEASE AND THAT, IF KNOWN BY HIM OR HER, WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY.

on the part of the Company.


 


7.           
Governing Law and Venue. All matters affecting this Agreement, including the validity thereof, are to be governed
by, and interpreted and construed in accordance with, the laws of the State of California applicable to contracts executed in and

AGREEMENT AND THE RELEASE PROVIDED FOR HEREIN VOLUNTARILY AND OF EMPLOYEE’S OWN FREE WILL.
