 3. Stock Subject to the Plan. 

(a) Stock Subject to the Plan. Subject to the provisions of Section 13 of the Plan, the maximum aggregate number of Shares that may
be issued under the Plan is 8,800,000, which represents the initial reserve of Shares of 5,500,000 Shares, which was subsequently increased by 3,300,000 Shares pursuant to the automatic share increase provision included in the Plan prior to the
effective date of the amendment and restatement of the Plan. The Shares may be authorized, but unissued, or reacquired Common Stock. Notwithstanding the foregoing and, subject to adjustment as provided in Section 13, the maximum number of
Shares that may be issued upon the exercise of Incentive Stock Options will equal the aggregate Share number stated in this Section 3(a), plus, to the extent allowable under Section 422 of the Code and the Treasury Regulations promulgated
thereunder, any Shares that become available for issuance under the Plan pursuant to Sections 3(b) and 3(c). 
 (b) Lapsed Awards. To
the extent an Award expires, is surrendered pursuant to an Exchange Program or becomes unexercisable without having been exercised or, with respect to Restricted Stock, Restricted Stock Units, Performance Units or Performance Shares, is forfeited to
or repurchased by the Company due to failure to vest, the unpurchased Shares (or for Awards other than Options or Stock Appreciation Rights the forfeited or repurchased Shares), which were subject thereto will become available for future grant or
sale under the Plan (unless the Plan has terminated). Notwithstanding the foregoing (and except with respect to Shares of Restricted Stock that are forfeited rather than vesting), Shares that have actually been issued under the Plan under any Award
will not be returned to the Plan and will not become available for future distribution under the Plan; provided, however, that if Shares issued pursuant to Awards of Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units
are repurchased by the Company or are forfeited to the Company, such Shares will become available for future grant under the Plan. Shares used to pay the exercise price of an Award or to satisfy the tax withholding obligations related to an Award
will become available for future grant or sale under the Plan. To the extent an Award under the Plan is paid out in cash rather than Shares, such cash payment will not result in reducing the number of Shares available for issuance under the Plan.

Code.

vote at any annual or special meeting of Company’s shareholders. 
 (e) Delegation by the Committee. The Committee, in its sole
discretion and on such terms and conditions as it may provide, may delegate all or any part of its authority and powers under the Plan to one or more Directors or officers of the Company; provided, however, that the Committee may not delegate its
authority and powers (a) with respect to an Officer or (b) in any way which would jeopardize the Plan’s qualification under Code Section 162(m) or Rule 16b-3. 

5. Award Eligibility and Limitations. 

(a) Award Eligibility. Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Performance
Shares and Performance Units may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 
 (b) Award
Limitations. The following limits shall apply to the grant of any Award if, at the time of grant, the Company is a “publicly held corporation” within the meaning of Section 162(m) of the Code: 

(i) Options and Stock Appreciation Rights. Subject to adjustment as provided in Section 13, no Employee shall be granted within
any fiscal year of the Company one or more Options or Stock Appreciation Rights, which in the aggregate cover more than 500,000 Shares reserved for issuance under the Plan; provided, however, that in connection with an Employee’s initial
service as an Employee, an Employee may be granted Options or Stock Appreciation Rights, which in the aggregate cover up to an additional 1,000,000 Shares reserved for issuance under the Plan. 

  
 - 8 - 

 (ii) Restricted Stock and Restricted Stock Units. Subject to adjustment as provided in
Section 13, no Employee shall be granted within any fiscal year of the Company one or more awards of Restricted Stock or Restricted Stock Units, which in the aggregate cover more than 500,000 Shares reserved for issuance under the Plan;
provided, however, that in connection with an Employee’s initial service as an Employee, an Employee may be granted Restricted Stock or Restricted Stock Units, which in the aggregate cover up to an additional 1,000,000 Shares reserved for
issuance under the Plan. 
 (iii) Performance Units and Performance Shares. Subject to adjustment as provided in Section 13, no
Employee shall receive Performance Units or Performance Shares having a grant date value (assuming maximum payout) greater than two million dollars ($2 million) or covering more than 500,000 Shares, whichever is greater; provided, however, that in
connection with an Employee’s initial service as an Employee, an Employee may receive Performance Units or Performance Shares having a grant date value (assuming maximum payout) of up to an additional amount equal five million dollars ($5
million) or covering up to 1,000,000 Shares, whichever is greater. No Participant may be granted more than one award of Performance Units or Performance Shares for the same Performance Period. 

(c) Limitation on Grants to Non-Employee Directors. The maximum number of shares of Common
Stock subject to Awards granted under the Plan during any one fiscal year to any Outside Director, taken together with any cash fees paid by the Company to such Outside Director during such fiscal year for service as an Outside Director, will not
exceed $500,000 in total value (calculating the value of any such Awards based on the grant date fair value of such Awards for financial reporting purposes), including for this purpose, the value of any Awards that are received in lieu of all or a
portion of any annual committee cash retainers or other similar cash based payments. 
 6. Stock Options. 

(a) Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock
Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options will be taken into
account in the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted. With respect to the Committee’s authority in Section 4(b)(viii), if,
at the time of any such extension, the exercise price per Share of the Option is less than the Fair Market Value of a Share, the extension shall, unless otherwise determined by the Committee, be limited to the earlier of (1) the maximum term of
the Option as set by its original terms, or (2) ten (10) years from the grant date. Unless otherwise determined by the Committee, any extension of the term of an Option pursuant to this Section 4(b) (viii) shall comply with Code
Section 409A to the extent necessary to avoid taxation thereunder. 

  
 - 9 - 

 (b) Term of Option. The term of each Option will be stated in the Award Agreement. In the
case of an Incentive Stock Option, the term will be ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the
time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be
five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement. 
 (c) Option Exercise Price
and Consideration. 
 (i) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an
Option will be determined by the Administrator, subject to the following: 
 (1) In the case of an Incentive Stock Option 

(A) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant. 

(B) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise price will be no
less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (2) In the case of a Nonstatutory Stock
Option, the per Share exercise price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(3) Notwithstanding the foregoing, Options may be granted with a per Share exercise price of less than one hundred percent (100%) of the Fair
Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code. 

(ii) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the
Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised. 
 (iii) Form of
Consideration. The Administrator will determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of
consideration at the time of grant. Such consideration for both types of Options may consist 

  
 - 10 - 

 
entirely of: (1) cash; (2) check; (3) promissory note, to the extent permitted by Applicable Laws, (4) other Shares, provided that such Shares have a Fair Market Value on the date
of surrender equal to the aggregate exercise price of the Shares as to which such Option will be exercised and provided that accepting such Shares will not result in any adverse accounting consequences to the Company, as the Administrator determines
in its sole discretion; (5) consideration received by the Company under a broker-assisted (or other) cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with the Plan; (6) by net
exercise; (7) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws; or (8) any combination of the foregoing methods of payment. 

(d) Exercise of Option. 

(i) Procedure for Exercise: Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of the
Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 

An Option will be deemed exercised when the Company receives: (i) a notice of exercise (in such form as the Administrator may specify
from time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding taxes). Full payment may consist of any consideration
and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the
Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a
stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a
dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the Plan. 

(ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the
Participant’s termination as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent that the Option is vested on
the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for three
(3) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of
the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

  
 - 11 - 

 (iii) Disability of Participant. If a Participant ceases to be a Service Provider as a
result of the Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the Participant’s termination.
Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the
Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised following the
Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the Option be exercised later than the expiration of the term of such Option
as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the Administrator. If no such beneficiary has been
designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the
laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. Unless otherwise provided by the Administrator, if at the
time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will
terminate, and the Shares covered by such Option will revert to the Plan. 
 7. Restricted Stock. 

(a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time,
may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine. 

(b) Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the Period of
Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of Restricted
Stock until the restrictions on such Shares have lapsed. 
 (c) Transferability. Except as provided in this Section 7 or the
Award Agreement, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction. 

(d) Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock as
it may deem advisable or appropriate. 

  
 - 12 - 

 (e) Removal of Restrictions. Except as otherwise provided in this Section 7, Shares
of Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may determine. The
Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed. 
 (f) Voting Rights.
During the Period of Restriction, Service Providers holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. 

(g) Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock will be
credited with all dividends and other distributions that are paid by the Company on an equivalent number of Shares that are not subject to such restrictions. Any such dividends and other distributions shall be distributed to a Service Provider (with
or without interest or other earnings, as provided at the discretion of the Administrator) only if, when and to the extent the related Shares of Restricted Stock vest. Dividends and other distributions credited with respect to any Shares of
Restricted Stock that do not vest shall be forfeited. 
 (h) Return of Restricted Stock to Company. On the date set forth in the
Award Agreement, the Restricted Stock for which restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan. 

8. Restricted Stock Units. 

(a) Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. After the
Administrator determines that it will grant Restricted Stock Units under the Plan, it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions (if any) related to the grant, including the number of Restricted
Stock Units. 
 (b) Vesting Criteria and Other Terms. The Administrator will set vesting criteria in its discretion, which, depending
on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of Company-wide, business unit, or
individual goals (including, but not limited to, continued employment), or any other basis (including the passage of time) determined by the Administrator in its discretion. 

(c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will be entitled to receive a payout
as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a payout. 

(d) Dividend Equivalents. The Administrator may, in its sole discretion, provide that dividend equivalents will be credited in
connection with the grant of Restricted 

  
 - 13 - 

 
Stock Units that may be settled in cash, in Shares of equivalent value, or in some combination thereof. Any dividend equivalents credited with respect to Restricted Stock Units shall be equal in
value to the dividends and other distributions that are paid by the Company on an equivalent number of Shares and shall be settled in cash or Shares to the Participant (with or without interest or other earnings, as provided at the discretion of the
Administrator) only if, when and to the extent the related Restricted Stock Units vest. Dividend equivalents credited with respect to any Restricted Stock Unit that does not vest shall be forfeited. 

(e) Form and Timing of Payment. Payment of earned Restricted Stock Units will be made upon the date(s) determined by the Administrator
and set forth in the Award Agreement. The Administrator, in its sole discretion, may only settle earned Restricted Stock Units in cash, Shares, or a combination of both. 

(f) Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units will be forfeited to the Company.

 9. Stock Appreciation Rights. 

(a) Grant of Stock Appreciation Rights. Subject to the terms and conditions of the Plan, a Stock Appreciation Right may be granted to
Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion. 
 (b) Number of
Shares. The Administrator will have complete discretion to determine the number of Stock Appreciation Rights granted to any Service Provider. 

(c) Exercise Price and Other Terms. The per share exercise price for the Shares to be issued pursuant to exercise of a Stock
Appreciation Right will be determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, the Administrator, subject to the provisions of the Plan, will have
complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under the Plan. 
 (d) Stock Appreciation
Right Agreement. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms and conditions as the
Administrator, in its sole discretion, will determine. 
 (e) Expiration of Stock Appreciation Rights. A Stock Appreciation Right
granted under the Plan will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(b) relating to the maximum term and
Section 6(d) relating to exercise also will apply to Stock Appreciation Rights. 

  
 - 14 - 

 (f) Payment of Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation
Right, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying: 
 (i) The difference
between the Fair Market Value of a Share on the date of exercise over the exercise price; times 
 (ii) The number of Shares with respect
to which the Stock Appreciation Right is exercised. 
 At the discretion of the Administrator, the payment upon Stock Appreciation Right
exercise may be in cash, in Shares of equivalent value, or in some combination thereof. 
 10. Performance Units and Performance
Shares. 
 (a) Grant of Performance Units/Shares. Performance Units and Performance Shares may be granted to Service Providers at
any time and from time to time, as will be determined by the Administrator, in its sole discretion. The Administrator will have complete discretion in determining the number of Performance Units and Performance Shares granted to each Participant.

 (b) Value of Performance Units/Shares. Each Performance Unit will have an initial value that is established by the Administrator
on or before the date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant. 

(c) Performance Objectives and Other Terms. The Administrator will set Performance Goals or other vesting provisions (including,
without limitation, continued status as a Service Provider) in its discretion which, depending on the extent to which they are met, will determine the number or value of Performance Units/Shares that will be paid out to the Service Providers. The
time period during which the performance objectives or other vesting provisions must be met will be called the “Performance Period.” Each Award of Performance Units/Shares will be evidenced by an Award Agreement that will specify the
Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, or individual goals,
applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion. 
 (d) Measurement of
Performance Goals. Performance Goals shall be established by the Committee on the basis of targets to be attained (“Performance Targets”) with respect to one or more measures of business or financial performance (each, a
“Performance Measure”), subject to the following: 
 (i) Performance Measures. For each Performance Period, the
Committee shall establish and set forth in writing the Performance Measures, if any, and any particulars, components and adjustments relating thereto, applicable to each Participant. The Performance Measures, if any, will be objectively measurable
and will be based upon the achievement of a specified percentage or level in one or more objectively defined and non-discretionary factors pre-established by the
Committee. Performance Measures may be one or more of the following, as determined by the Committee: (i) pre-tax income or after-tax income;

  
 - 15 - 

 
(ii) income or earnings including operating income, earnings before or after taxes, interest, stock-based compensation expense, depreciation and/or amortization; (iii) net income excluding
amortization of intangible assets, depreciation and impairment of goodwill and intangible assets and/or excluding charges attributable to the adoption of new accounting pronouncements; (iv) earnings or book value per share (basic or diluted);
(v) return on assets (gross or net), return on investment, return on capital, or return on equity; (vi) return on revenues; (vii) cash flow, free cash flow, cash flow return on investment (discounted or otherwise), net cash provided by
operations, or cash flow in excess of cost of capital; (viii) economic value created; (ix) operating margin or profit margin; (x) stock price or total stockholder return; (xi) income or earnings from continuing operations;
(xii) capital expenditures, cost targets, reductions and savings and expense management; and (xiii) strategic business criteria, consisting of one or more objectives based on meeting specified market penetration or market share, geographic
or product specialty expansion, recruitment and retention goals, or objective customer or agent satisfaction , and objective goals relating to divestitures, joint ventures, mergers, acquisitions and similar transactions, each with respect to the
Company and/or one or more of its affiliates or operating units. 
 (ii) Committee Discretion on Performance Measures. As determined
in the discretion of the Committee, the Performance Measures for any Performance Period may (a) differ from Participant to Participant, Performance Period to Performance Period and from Award to Award, (b) be based on the performance of
the Company as a whole, the performance of a specific Participant or against any affiliate(s), a particular segment(s), a business unit(s) or a product(s) of the Company or individual project company, (c) be measured on a per share, share per
capita basis, and/or other objective basis, (d) be measured on a pre-tax or after-tax basis, and (e) be measured on an absolute basis or in relative terms
(including, but not limited to, any increase (or decrease) over the passage of time and/or any measurement against other companies or financial or business or stock index metrics particular to the Company), (f) be measured using an actual foreign
exchange rate or on a foreign exchange neutral basis. Without limiting the foregoing, the Committee shall adjust any performance criteria, Performance Measures or other feature of an Award that relates to or is wholly or partially based on the
number of, or the value of, any stock of the Company, to reflect any stock dividend or split, repurchase, recapitalization, combination, or exchange of shares or other similar changes in such stock. Awards issued to Participants who are not subject
to the limitations of Code Section 162(m) or Awards to Participants that are not intended to comply with the requirements of Code Section 162(m) may, in either case, take into account other factors (including subjective factors). 

(e) Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of Performance Units/Shares will
be entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding Performance Goals or other vesting provisions
have been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any Performance Goals or other vesting provisions for such Performance Unit/Share. 

(f) Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance Units/Shares will be made upon the time set
forth in the applicable Award 

  
 - 16 - 

 
Agreement. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the
earned Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof. 
 (g) Cancellation of
Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or unvested Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan. 

11. Leaves of Absence/Transfer Between Locations. Unless the Administrator provides otherwise, vesting of Awards granted hereunder will
be suspended during any unpaid leave of absence unless contrary to Applicable Law. A Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Participant’s employer or (ii) transfers between
locations of the Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed three (3) months, unless reemployment upon expiration of such leave is guaranteed by statute or
contract. If reemployment upon expiration of a leave of absence approved by the Participant’s employer is not so guaranteed, then six (6) months following the first (1st) day of such leave any Incentive Stock Option held by the Participant
will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option. 
 12.
Transferability of Awards. Unless determined otherwise by the Administrator, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and
may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator makes an Award transferable, such Award will contain such additional terms and conditions as the Administrator deems appropriate. 

13. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 

(a) Adjustments. In the event of a stock split, reverse stock split, stock dividend, combination, consolidation, recapitalization
(including a recapitalization through a large nonrecurring cash dividend) or reclassification of the Shares, subdivision of the Shares, a rights offering, a reorganization, merger, spin-off, split-up, repurchase, or exchange of Common Stock or other securities of the Company or other significant corporate transaction, or other change affecting the Common Stock occurs, the Administrator, in order to
prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number, kind and class of securities that may be delivered under the Plan
and/or the number, class, kind and price of securities covered by each outstanding Award, the numerical Share limits in Section 3 of the Plan. Notwithstanding the forgoing, all adjustments under this Section 13 shall be made in a manner
that does not result in taxation under Code Section 409A. 
 (b) Dissolution or Liquidation. In the event of the proposed
winding up, dissolution or liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will
terminate immediately prior to the consummation of such proposed action. 

  
 - 17 - 

 (c) Change in Control. In the event of a merger or Change in Control, each outstanding
Award will be treated as the Administrator determines, including, without limitation, that each Award be assumed, cancelled or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor
corporation. The Administrator will not be required to treat all Awards similarly in the transaction. 
 Except as set forth in an Award
Agreement, in the event that the successor corporation does not assume or substitute for the Award, the Participant will fully vest in and have the right to exercise all of his or her outstanding Options and Stock Appreciation Rights, including
Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all Performance Goals or other
vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not assumed or substituted in the event of a Change in Control,
the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock
Appreciation Right will terminate upon the expiration of such period. 
 For the purposes of this subsection (c), an Award will be
considered assumed if, following the Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities
or property) received in the Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); provided, however, that if such consideration received in the Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor
corporation, provide for the consideration to be received upon the exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, Performance Unit or Performance Share, for each Share subject to such Award, to be
solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the Change in Control. 

Notwithstanding anything in this Section 13(c) to the contrary, an Award that vests, is earned or
paid-out upon the satisfaction of one or more Performance Goals will not be considered assumed if the Company or its successor modifies any of such Performance Goals without the Participant’s consent;
provided, however, a modification to such Performance Goals only to reflect the successor corporation’s post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption. 

  
 - 18 - 

 14. Tax. 

(a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof) or prior to any
time the Award or Shares are subject to taxation, the Company and/or the Participant’s employer will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal,
state, local, foreign or other taxes (including the Participant’s FICA obligation or social insurance contributions) required to be withheld with respect to such Award (or exercise thereof). 

(b) Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to
time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (a) paying cash, (b) electing to have the Company withhold otherwise deliverable cash or Shares having a Fair Market
Value equal to the minimum statutory amount required to be withheld, or (c) delivering to the Company already-owned Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld or Shares having a Fair Market
Value in excess of such amount that have been held for such period. Except as otherwise determined by the Administrator, the Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to
be withheld. 
 (c) Compliance With Code Section 409A. Awards will be designed and operated in such a manner that
they are either exempt from the application of, or comply with, the requirements of Code Section 409A such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code
Section 409A. The Plan and each Award Agreement under the Plan is intended to meet the requirements of Code Section 409A (or an exemption therefrom) and will be construed and interpreted in accordance with such intent, except as otherwise
determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Code Section 409A the Award will be granted, paid, settled or deferred in a manner that will
meet the requirements of Code Section 409A (or an exemption therefrom), such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A. In no event will the
Company be responsible for or reimburse a Participant for any taxes or other penalties incurred as a result of applicable of Code Section 409A. 

15. Clawback. In the event of a restatement of incorrect financial results, the Administrator shall review all Awards held by Officers
that (i) were earned based on performance or vested during the course of the financial period subject to such restatement or (ii) were granted during or within one year following such financial period. If any Award would have been lower or
would not have been earned, vested or granted based on such restated financial results, the Administrator shall, if it determines appropriate in its sole discretion and to the extent permitted by Applicable Law, (a) cancel such Award, in whole
or in part, whether or not earned, vested or payable or (b) require the Participant to repay to the Company an amount equal to all or any portion of the value of any gains from the grant, vesting or payment of the Award that would not have been
realized had the restatement not occurred. Notwithstanding the foregoing, to the extent required to comply with Applicable Law, the Company may unilaterally amend this Section 15. 

  
 - 19 - 

 16. No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a
Participant any right with respect to continuing the Participant’s relationship as a Service Provider with the Company, or (if different) the Participant’s employer, nor will they interfere in any way with the Participant’s right or
the Participant’s employer’s right to terminate such relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 

17. Date of Grant. The date of grant of an Award will be, for all purposes, the date on which the Administrator makes the determination
granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant within a reasonable time after the date of such grant. 

18. Term of Plan. The Plan initially became effective October 7, 2013 (the “Initial Effective Date”). The
Plan will continue in effect for a term of ten (10) years from the Initial Effective Date, unless terminated earlier under Section 18 of the Plan. The provisions of the Plan, as amended and restated herein, shall be effective as of the
date approved by the Committee, subject to Section 22 below. 
 19. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Committee may at any time amend, alter, suspend or terminate the Plan. 

(b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary and desirable to
comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the
Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of the Plan will not affect
the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

20. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance
and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance. 

(b) Investment Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award to
represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation
is required. 
 21. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having
jurisdiction, which authority is deemed by the Company’s 

  
 - 20 - 

 
counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such
requisite authority will not have been obtained. 
 22. Stockholder Approval. The amendment and restatement of the Plan will be
subject to approval by the stockholders of the Company at the annual meeting of stockholders that will be held in 2017. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws. 

23. Governing Law. The Plan and all Awards hereunder shall be construed in accordance with and governed by the laws of the State of
California, but without regard to its conflict of law provisions.

	$60,000,000.00	  	 Woodland Hills, California

October 16, 2017

 FOR VALUE RECEIVED, the undersigned MARCUS & MILLICHAP, INC. (“Borrower”) promises to pay
to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION (“Bank”) at its office at MAC E2155-011, 21255 Burbank Blvd., Suite 110, Woodland Hills, California 91367, or at such other place as the holder

the Credit Agreement, as defined herein, with interest thereon, to be computed on each advance from the date of its disbursement as set forth herein. 

DEFINITIONS: 
 As used herein, the following
terms shall have the meanings set forth after each, and any other term defined in this Note shall have the meaning set forth at the place defined: 

(a) “Base Rate” means, for any day, a fluctuating rate equal to the highest of: (i) the Prime Rate in effect on such day,
(ii) a rate determined by Bank to be one and one-half percent (1.50%) above Daily One Month LIBOR in effect on such day, and (iii) the Federal Funds Rate plus one and
one-half percent (1.50%). 
 (b) “Daily One Month LIBOR” means, for any day, the rate of
interest equal to LIBOR then in effect for delivery for a one (1) month period . 
 (c) “Federal Funds Rate” means, for any
day, the rate per annum equal to the weighted average of the rates on overnight Federal funds transactions with members of the Federal Reserve System arranged by Federal funds brokers for the immediately preceding day, as published by the Federal
Reserve Bank of New York; provided that if no such rate is so published on any day, then the Federal Funds Rate for such day shall be the rate most recently published, and further provided that if the Fed Funds Rate determined as provided above
would be less than zero percent (0.0%), then the Fed Funds Rate shall be deemed to be zero percent (0.0%). 
 (d) “LIBOR” means
(i) for the purpose of calculating effective rates of interest for loans making reference to LIBOR Periods, the rate of interest per annum determined by Bank based on the rate for United States dollar deposits for delivery on the first day of
each LIBOR Period for a period approximately equal to such LIBOR Period as published by the ICE Benchmark Administration Limited, a United Kingdom company, at approximately 11:00 a.m., London time, two London Business Days prior to the first day of
such LIBOR Period (or if not so published, then as determined by Bank from another recognized source or interbank quotation), or (ii) for the purpose of calculating effective rates of interest for loans making reference to Daily One Month
LIBOR, the rate of interest per annum determined by Bank based on the rate for United States dollar deposits for delivery of funds for one (1) month as published by the ICE Benchmark Administration Limited, a United Kingdom company, at
approximately 11 :00 a.m., London time, or, for any day not a London Business Day, the immediately preceding London Business Day (or if not so published, then as determined by Bank from another recognized source or interbank quotation); provided,
however, that if LIBOR determined as provided above would be less than zero percent (0.0%), then LIBOR shall be deemed to be zero percent (0.0%). 

  

					
		  	-1-	  	

 (e) “LIBOR Period” means a period commencing on a New York Business Day and continuing
for one (1 ), two (2), three (3), six (6) or twelve (12) months, as designated by Borrower, during which all or a portion of the outstanding principal balance of this Note bears interest determined in relation to LIBOR; provided however,
that (i) no LIBOR Period may be selected for a principal amount less than One Million Dollars ($1 ,000,000.00), (ii) if the day after the end of any LIBOR Period is not a New York Business Day (so that a new LIBOR Period could not be selected
by Borrower to start on such day), then such LIBOR Period shall continue up to, but shall not include, the next New York Business Day after the end of such LIBOR Period, unless the result of such extension would be to cause any immediately following
LIBOR Period to begin in the next calendar month in which event the LIBOR Period shall continue up to, but shall not include, the New York Business Day immediately preceding the last day of such LIBOR Period, and (iii) no LIBOR Period shall
extend beyond the scheduled maturity date hereof. 
 (f) “London Business Day” means any day that is a day for trading by and
between banks in dollar deposits in the London interbank market. 
 (g) “New York Business Day” means any day except a Saturday,
Sunday or any other day on which commercial banks in New York are authorized or required by law to close. 
 (h) “Prime Rate”
means at any time the rate of interest most recently announced within Bank at its principal office as its Prime Rate, with the understanding that the Prime Rate is one of Bank’s base rates and serves as the basis upon which effective rates of
interest are calculated for those loans making reference thereto, and is evidenced by the recording thereof after its announcement in such internal publication or publications as Bank may designate. If the rate of interest announced by Bank as its
Prime Rate at any time is less than zero percent (0.0%), then for purposes of this Note the Prime Rate shall be deemed to be zero percent (0.0%). 

(i) “State Business Day” means any day except a Saturday, Sunday or any other day on which commercial banks in the jurisdiction
described in “Governing Law” herein are authorized or required by law to close. 
 INTEREST: 

(a) Interest. The outstanding principal balance of this Note shall bear interest (computed on the basis of a 360-day year, actual days elapsed) either (i) at a fluctuating rate per annum equal to the Base Rate in effect from time to time, or (ii) at a fixed rate per annum determined by Bank to be eight hundred
seventy five one thousandths of one percent (0.875%) above LIBOR in effect on the first day of the applicable LIBOR Period. When interest is determined in relation to the Base Rate, each change in the rate of interest hereunder shall become
effective on the date each Base Rate change is announced within Bank. With respect to each LIBOR selection hereunder, Bank is hereby authorized to note the date, principal amount, interest rate and LIBOR Period applicable thereto and any payments
made thereon on Bank’s books and records (either manually or by electronic entry) and/or on any schedule attached to this Note, which notations shall be prima facie evidence of the accuracy of the information noted. 

  

					
		  	-2-	  	

 (b) Selection of Interest Rate Options. Subject to the provisions herein regarding LIBOR
Periods and the prior notice required for the selection of a LIBOR interest rate, (i) at any time any portion of this Note bears interest determined in relation to LIBOR for a LIBOR Period, it may be continued by Borrower at the end the LIBOR
Period applicable thereto so that all or a portion thereof bears interest determined in relation to the Base Rate or to LIBOR for a new LIBOR Period designated by Borrower, (ii) at any time any portion of this Note bears interest determined in
relation to the Base Rate, Borrower may convert all or a portion thereof so that it bears interest determined in relation to LIBOR for a LIBOR Period designated by Borrower, and (iii) at the time this Note is disbursed, Borrower may choose to
have all or a portion thereof bear interest determined in relation to the Base Rate or to LIBOR for a LIBOR Period designated by Borrower. 
 To select an
interest rate option hereunder determined in relation to LIBOR for a LIBOR Period, Borrower shall give Bank notice thereof that is received by Bank prior to 11:00 a.m. in the jurisdiction described in “Governing Law” herein on a State
Business Day at least two State Business Days prior to the first day of the LIBOR Period, or at a later time during such State Business Day if Bank, at its sole discretion, accepts Borrower’s notice and quotes a fixed rate to Borrower. Such
notice shall specify: (A) the interest rate option selected by Borrower, (B) the principal amount subject thereto, and (C) for each LIBOR selection, the length of the applicable LIBOR Period. If Bank has not received such notice in
accordance with the foregoing before principal is disbursed hereunder or before the end of any LIBOR Period, Borrower shall be deemed to have made a Base Rate interest selection for such disbursement or the principal amount to which such LIBOR
Period applied. Any such notice may be given by telephone (or such other electronic method as Bank may permit) so long as it is given in accordance with the foregoing and, with respect to each LIBOR selection, if requested by Bank, Borrower provides
to Bank written confirmation thereof not later than three State Business Days after such notice is given. Borrower shall reimburse Bank immediately upon demand for any loss or expense (including any loss or expense incurred by reason of the
liquidation or redeployment of funds obtained to fund or maintain a LIBOR borrowing) incurred by Bank as a result of the failure of Borrower to accept or complete a LIBOR borrowing hereunder after making a request therefor. Any reasonable
determination of such amounts by Bank shall be conclusive and binding upon Borrower. Should more than one person or entity sign this Note as a Borrower, any notice required above may be given by any one Borrower acting alone, which notice shall be
binding on all other Borrowers. 
 (c) Taxes and Regulatory Costs. Borrower shall pay to Bank immediately upon demand, in addition to
any other amounts due or to become due hereunder, any and all (i) withholdings, interest equalization taxes, stamp taxes or other taxes (except income and franchise taxes) imposed by any domestic or foreign governmental authority and related in
any manner to LIBOR, and (ii) costs, expenses and liabilities arising from or in connection with reserve percentages prescribed by the Board of Governors of the Federal Reserve System (or any successor) for “Eurocurrency Liabilities”
(as defined in Regulation D of the Federal Reserve Board, as amended), assessment rates imposed by the Federal Deposit Insurance Corporation, or similar requirements or costs imposed by any domestic or foreign governmental authority or resulting
from compliance by Bank with any request or directive (whether or not having the force of law) from any central bank or other governmental authority and related in any manner to LIBOR. In determining which of the foregoing are attributable to any
LIBOR option available to Borrower hereunder, any reasonable allocation made by Bank among its operations shall be conclusive and binding upon Borrower.

 (d) Default Interest. From and after the maturity date of this Note, or such earlier date
as all principal owing hereunder becomes due and payable by acceleration or otherwise, or upon the occurrence and during the continuance of an Event of Default, then at the option of Bank, in its sole and absolute discretion, the outstanding
principal balance of this Note shall bear interest at an increased rate per annum (computed on the basis of a 360-day year, actual days elapsed) equal to four percent (4%) above the rate of interest from time
to time applicable to this Note. 
 INTEREST RATE ADJUSTMENTS: 

(a) Initial LIBOR Margin. The initial LIBOR margin applicable to this Note shall be as set forth in the Interest paragraph
herein. 
 (b) LIBOR Rate Adjustments. Bank shall adjust the LIBOR margin used to determine the rate of interest applicable to LIBOR
options selected by Borrower under this Note on a quarterly basis, commencing with Borrower’s fiscal quarter ending December 31, 2017, if required to reflect a change in Borrower’s ratio of Total Funded Debt to EBITDA (as defined in
the Credit Agreement referenced herein), in accordance with the following grid: 
  

					
	 Total Funded Debt to EBITDA
	  	Applicable
LIBOR
Margin	 
	 0.0:1.0 to 1.0:1.0
	  	 	0.875	% 
		
	 1.01:1.0 to 1.50:1.0
	  	 	1.000	% 
		
	 1.51:1.0 to 2.0:1.0
	  	 	1.125	% 

 Each such adjustment shall be effective on the first business day of Borrower’s fiscal quarter following the quarter
during which Bank receives and reviews Borrower’s most current fiscal quarter-end financial statements in accordance with any requirements established by Bank for the preparation and delivery thereof. 

BORROWING AND REPAYMENT: 
 (a) Borrowing and
Repayment of Principal. Borrower may from time to time during the term of this Note borrow, partially or wholly repay its outstanding borrowings, and reborrow, subject to all of the limitations, terms and conditions of this Note and of any
document executed in connection with or governing this Note; provided however, that the total outstanding borrowings under this Note shall not at any time exceed the principal amount stated above. The unpaid principal balance of this obligation at
any time shall be the total amounts advanced hereunder by the holder hereof less the amount of principal payments made hereon by or for Borrower, which balance may be endorsed hereon from time to time by the holder. The outstanding principal balance
of this Note shall be due and payable in full on June 1, 2020. 
 (b) Payment of Interest. Interest accrued on this Note shall
be payable on the first day of each month, commencing November 1, 2017, and on the maturity date set forth above. 
 (c)
Advances. Advances hereunder, to the total amount of the principal sum stated above, may be made by the holder at the oral or written request of (i) Borrower’s Chief 

  

					
		  	-4-	  	

 
Executive Officer, Chief Financial Officer or Chief Accounting Officer, any one acting alone, who are authorized to request advances and direct the disposition of any advances until written
notice of the revocation of such authority is received by the holder at the office designated above, or (ii) any person, with respect to advances deposited to the credit of any deposit account of Borrower, which advances, when so deposited,
shall be conclusively presumed to have been made to or for the benefit of Borrower regardless of the fact that persons other than those authorized to request advances may have authority to draw against such account. The holder shall have no
obligation to determine whether any person requesting an advance is or has been authorized by Borrower. 
 (d) Application of
Payments. Each payment made on this Note shall be credited first, to any interest then due and second, to the outstanding principal balance hereof. All payments credited to principal shall be applied first, to the outstanding principal balance
of this Note which bears interest determined in relation to the Base Rate, if any, and second, to the outstanding principal balance of this Note which bears interest determined in relation to LIBOR, with such payments applied to the oldest LIBOR
Period first. 
 PREPAYMENT: 
 (a) Base
Rate. Borrower may prepay principal on any portion of this Note which bears interest determined in relation to the Base Rate at any time, in any amount and without penalty. 

(b) LIBOR. Borrower may prepay principal on any portion of this Note which bears interest determined in relation to LIBOR at any time
and in the minimum amount of One Million Dollars ($1,000,000.00); provided however, that if the outstanding principal balance of such portion of this Note is less than said amount, the minimum prepayment amount shall be the entire outstanding
principal balance thereof. In consideration of Bank providing this prepayment option to Borrower, or if any such portion of this Note shall become due and payable at any time prior to the last day of the LIBOR Period applicable thereto by
acceleration or otherwise, Borrower shall pay to Bank immediately upon demand a fee which is the sum of the discounted monthly differences for each month from the month of prepayment through the month in which such LIBOR Period matures, calculated
as follows for each such month: 
  

	 	(i)	Determine the amount of interest which would have accrued each month on the amount prepaid at the interest rate applicable to such amount had it remained outstanding until the last day of the LIBOR Period
applicable thereto. 

  

	 	(ii)	Subtract from the amount determined in (i) above the amount of interest which would have accrued for the same month on the amount prepaid for the remaining term of such LIBOR Period at LIBOR in effect on the
date of prepayment for new loans made for such term and in a principal amount equal to the amount prepaid. 

  

	 	(iii)	If the result obtained in (ii) for any month is greater than zero, discount that difference by LIBOR used in (ii) above. 

Borrower acknowledges that prepayment of such amount may result in Bank incurring additional costs, expenses and/or liabilities, and that it is difficult to
ascertain the full extent of such costs, expenses and/or liabilities. Borrower, therefore, agrees to pay the above-described prepayment fee and agrees that said amount represents a reasonable estimate of the prepayment costs, expenses and/or
liabilities of Bank. If Borrower fails to pay any prepayment fee when due, the 

  

					
		  	-5-	  	

 
amount of such prepayment fee shall thereafter bear interest until paid at a rate per annum zero percent (0.00%) above the Prime Rate in effect from time to time (computed on the basis of a 360-day year, actual days elapsed). 
 (c) Application of Prepayments. If principal under this Note
is payable in more than one installment, then any prepayments of principal shall be applied to the most remote principal installment or installments then unpaid. 

EVENTS OF DEFAULT: 
 This Note is made pursuant
to and is subject to the terms and conditions of that certain Credit Agreement between Borrower and Bank dated as of June 1, 2014, as amended from time to time (the “Credit Agreement”). Any default in the payment or performance of any
obligation under this Note, or any defined event of default under the Credit Agreement, shall constitute an “Event of Default” under this Note. 

MISCELLANEOUS: 
 (a) Remedies. Upon the
sale, transfer, hypothecation, assignment or other encumbrance, whether voluntary, involuntary or by operation of law, of all or any interest in any real property securing this Note, if any, or upon the occurrence of any Event of Default, the holder
of this Note, at the holder’s option, may declare all sums of principal and interest outstanding hereunder to be immediately due and payable without presentment, demand, notice of nonperformance, notice of protest, protest or notice of
dishonor, all of which are expressly waived by Borrower, and the obligation, if any, of the holder to extend any further credit hereunder shall immediately cease and terminate. Borrower shall pay to the holder immediately upon demand the full amount
of all payments, advances, charges, costs and expenses, including reasonable attorneys’ fees (to include outside counsel fees and all allocated costs of the holder’s in-house counsel) , expended or
incurred by the holder in connection with the enforcement of the holder’s rights and/or the collection of any amounts which become due to the holder under this Note whether or not suit is brought, and the prosecution or defense of any action in
any way related to this Note, including without limitation, any action for declaratory relief, whether incurred at the trial or appellate level, in an arbitration proceeding or otherwise, and including any of the foregoing incurred in connection
with any bankruptcy proceeding (including without limitation, any adversary proceeding, contested matter or motion brought by Bank or any other person) relating to Borrower or any other person or entity. 

(b) Obligations Joint and Several. Should more than one person or entity sign this Note as a Borrower, the obligations of each such
Borrower shall be joint and several. 
 (c) Governing Law. This Note shall be governed by and construed in accordance with the laws
of California, but giving effect to federal laws applicable to national banks, without reference to the conflicts of law or choice of law principles thereof.
