added on the first day of the Company’s Fiscal Year for three years beginning in 2006 and ending after the 2008 annual increase equal to the least of (i) 3% of the outstanding Shares on such date or (ii) an amount determined by
the Board. The Shares may be authorized, but unissued, or reacquired Common Stock. 
 Any Shares subject to Options or SARs shall be counted
against the numerical limits of this Section 3 as one Share for every Share subject thereto. Any Shares of Restricted Stock or Shares subject to Performance Shares or Restricted Stock Units with a per share or unit purchase price 

  

 6 

 
lower than 100% of Fair Market Value on the date of grant shall be counted against the numerical limits of this Section 3 as two Shares for every one
Share subject thereto. To the extent that a Share that was subject to an Award that counted as two Shares against the Plan reserve pursuant to the preceding sentence is recycled back into the Plan under the next paragraph of this Section 3, the
Plan shall be credited with two Shares. 
 If an Award expires or becomes unexercisable without having been exercised in full or is
surrendered pursuant to an Exchange Program, or, with respect to Options, Restricted Stock, Performance Shares or Restricted Stock Units, is forfeited to or repurchased by the Company, the unpurchased Shares (or for Awards other than Options and
SARs, the forfeited or repurchased shares) which were subject thereto shall become available for future grant or sale under the Plan (unless the Plan has terminated). With respect to SARs, Shares actually issued pursuant to an SAR as well as the
Shares withheld to pay the exercise price shall cease to be available under the Plan. Shares that have actually been issued under the Plan under any Award shall not be returned to the Plan and shall not become available for future distribution under
the Plan; provided, however, that if Shares of Restricted Stock, Performance Shares or Restricted Stock Units are repurchased by the Company at their original purchase price or are forfeited to the Company, such Shares shall become available for
future grant under the Plan. Shares used to pay the exercise price of an Option or the purchase price of Restricted Stock shall not become available for future grant or sale under the Plan. Shares used to satisfy tax withholding obligations shall
not 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 stock, such cash payment shall not reduce the number of Shares available for issuance under the Plan. Any payout of
Dividend Equivalents, because they are payable only in cash, shall not reduce the number of Shares available for issuance under the Plan. Conversely, any forfeiture of Dividend Equivalents shall not increase the number of Shares available for
issuance under the Plan. 
 4.    Administration of the Plan. 
 (a)    Procedure. 
 (i)    Multiple Administrative Bodies. The Board or different Committees with respect to different groups of Service Providers may administer the Plan. 
 (ii)    Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards granted
hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, the Plan shall be administered by a Committee of two or more “outside directors” within the meaning of Section 162(m) of
the Code. 
 (iii)    Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under Rule
16b-3, the transactions contemplated hereunder shall be structured to satisfy the requirements for exemption under Rule 16b-3. 
 (iv)    Other Administration. Other than as provided above, the Plan shall be administered by (a) the Board or (b) a Committee, which committee shall be constituted to satisfy Applicable Laws.

  

 7 

 (b)    Powers of the Administrator. Subject to the provisions of the Plan, and
in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion: 
 (i)    to determine the Fair Market Value; 
 (ii)    to select the
Service Providers to whom Awards may be granted hereunder; 
 (iii)    to determine the number of shares of Common Stock
or equivalent units to be covered by each Award granted hereunder; 
 (iv)    to approve forms of Award Agreement for
use under the Plan; 
 (v)    to determine the terms and conditions, not inconsistent with the terms of the Plan, of any
Award granted hereunder. Such terms and conditions include, but are not limited to, the exercise price, the date of grant, the time or times when Awards may be exercised (or are earned) (which may be based on performance criteria), any vesting
acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator, in its sole discretion, shall determine; 
 (vi)    to institute an Exchange Program; however, the Administrator may not institute an Exchange Program without shareholder
approval. 
 (vii)    to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan;

 (viii)    to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations
relating to sub-plans established for the purpose of satisfying applicable foreign laws and/or qualifying for preferred tax treatment under foreign tax laws; 
 (ix)    to modify or amend each Award (subject to Section 19(c) of the Plan), including the discretionary authority to extend the post-termination exercisability period of Options and SARs
longer than is otherwise provided for in the Plan; 
 (x)    to allow Participants to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares or cash to be issued upon exercise of an Option, SAR or right to purchase Restricted Stock or upon vesting or payout of another Award, that number of Shares or cash having a Fair
Market Value equal to the minimum amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have
Shares or cash withheld for this purpose shall be made in such form and under such conditions as the Administrator may deem necessary or advisable; 
 (xi)    to determine whether Awards will be adjusted for Dividend Equivalents; 
  

 8 

 (xii)    to authorize any person to execute on behalf of the Company any instrument
required to effect the grant of an Award previously granted by the Administrator; and 
 (xiii)    to make all other
determinations deemed necessary or advisable for administering the Plan. 
 (c)    Effect of Administrator’s
Decision. The Administrator’s decisions, determinations and interpretations shall be final and binding on all Participants and any other holders of Awards. 
 5.    Eligibility. Awards may be granted to Service Providers; provided, however, that Incentive Stock Options may be granted only to Employees. 
 6.    No Employment Rights. Neither the Plan nor any Award shall confer upon a Participant any right with respect to
continuing the Participant’s relationship as an Employee or other Service Provider with the Company or its Subsidiaries, nor shall they interfere in any way with the Participant’s right or the Company’s or Subsidiary’s right, as
the case may be, to terminate such relationship at any time, with or without cause. 
 7.    Code Section 162(m)
Provisions. 
 (a)    Option and SAR Annual Share Limit. No Participant shall be granted, in any Fiscal Year,
Options and Stock Appreciation Rights to purchase more than 500,000 Shares; provided, however, that such limit shall be 250,000 Shares in the Participant’s first Fiscal Year of Company service. 
 (b)    Restricted Stock, Performance Share and Restricted Stock Unit Annual Limit. No Participant shall be granted, in any
Fiscal Year, more than 250,000 Shares in the aggregate of the following: (i) Restricted Stock, (ii) Performance Shares, or (iii) Restricted Stock Units; provided, however, that such limit shall be 125,000 Shares in the
Participant’s first Fiscal Year of Company service. 
 (c)    Section 162(m) Performance Restrictions.
For purposes of qualifying grants of Restricted Stock, Performance Shares or Restricted Stock Units as “performance-based compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may set restrictions based
upon the achievement of Performance Goals. The Performance Goals shall be set by the Administrator on or before the latest date permissible to enable the Restricted Stock, Performance Shares or Restricted Stock Units to qualify as
“performance-based compensation” under Section 162(m) of the Code. In granting Restricted Stock, Performance Shares or Restricted Stock Units which are intended to qualify under Section 162(m) of the Code, the Administrator shall
follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Award under Section 162(m) of the Code (e.g., in determining the Performance Goals). 
 (d)    Changes in Capitalization. The numerical limitations in Sections 7(a) and (b) shall be adjusted
proportionately in connection with any change in the Company’s capitalization as described in Section 17(a). 
  

 9 

 (e)    If an Award is cancelled in the same Fiscal Year in which it was granted
(other than in connection with a transaction described in Section 17 of the Plan), the cancelled Award will be counted against the limits set forth in subsections (a) and (b) above. For this purpose, if the exercise price of an Option
is reduced, the transaction will be treated as a cancellation of the Option and the grant of a new Option. 
 8.    Term of Plan. Subject to Section 23 of the Plan, the Plan will become effective upon its adoption by the Board. It will continue in effect for a term of ten (10) years unless terminated earlier
under Section 19 of the Plan. 
 9.    Stock Options. 
 (a)    Type of Option. Each Option shall be designated in the Award Agreement as either an Incentive Stock Option or a
Nonstatutory Stock Option. However, not withstanding 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 $100,000, such Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 9(a), Incentive Stock Options shall be taken into account in
the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted. 
 (b)    Term. The term of each Option shall be stated in the Award Agreement. In the case of an Incentive Stock Option, the term shall 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 shall 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 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 110% of the Fair Market Value per Share on the date of grant. 
 (2)    In the case of all other Options,
the per Share exercise price will be no less than 100% of the Fair Market Value per Share on the date of grant. 
  

 10 

 (3)    Notwithstanding the foregoing, Options may be granted with a per Share
exercise price of less than 100% of the Fair Market Value per Share on the date of grant pursuant to a merger or other corporate transaction. 
 (ii)    Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator shall fix the period within which the Option may be exercised and shall determine any conditions which must be
satisfied before the Option may be exercised. 
 (iii)    Form of Consideration. The Administrator shall
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 shall determine the acceptable form of consideration at the time of grant. Subject
to Applicable Laws, such consideration may consist entirely of: 
 (1)    cash; 
 (2)    check; 
 (3)    promissory note; 
 (4)    other Shares which have a Fair Market Value on the date
of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised and which meet the conditions established by the Administrator to avoid adverse accounting consequences (as determined by the Administrator);

 (5)    consideration received by the Company under a cashless exercise program implemented by the Company in
connection with the Plan; 
 (6)    a reduction in the amount of any Company liability to the Participant, including any
liability attributable to the Participant’s participation in any Company-sponsored deferred compensation program or arrangement; 
 (7)    any combination of the foregoing methods of payment; 
 (8)    such other
consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws; or 
 (9)    any combination of the foregoing methods of payment. 
 10.    Stock Appreciation
Rights. 
 (a)    Grant of SARs. Subject to the terms and conditions of the Plan, a SAR 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. 
  

 11 

 (b)    Number of Shares. The Administrator will have complete discretion to
determine the number of SARs granted to any Service Provider, subject to the limits set forth in Section 7. 
 (c)    Exercise Price and Other Terms. The Administrator, subject to the provisions of the Plan, will have complete discretion to determine the terms and conditions of SARs granted under the Plan. 
 (d)    Exercise of SARs. SARs will be exercisable on such terms and conditions as the Administrator, in its sole discretion,
will determine. 
 (e)    SAR Agreement. Each SAR grant will be evidenced by an Award Agreement that will specify
the exercise price, the term of the SAR, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 
 (f)    Expiration of SARs. An SAR granted under the Plan will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement; provided,
however, that no SAR will have a term of more than ten (10) years from the date of grant. 
 (g)    Payment of
SAR Amount. Upon exercise of an SAR, 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 SAR is exercised. 
 (h)    Form of Payment. The Company’s obligation arising upon the exercise of a SAR may be paid in Common Stock or in cash, or in any combination of Common Stock and cash, as the Administrator, in its sole
discretion, may determine. Shares issued upon the exercise of a SAR shall be valued at their Fair Market Value as of the date of exercise. 
 11.    Exercise of Option or SAR. 
 (a)    Procedure for Exercise; Rights as a
Shareholder. Any Option or SAR granted hereunder shall 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 or SAR shall be deemed exercised when the Company receives: (i) written or electronic
notice of exercise (in accordance with the terms of the Option or SAR) from the person entitled to exercise the Option or SAR, and (ii) full payment for the Shares with respect to which the Option is exercised. 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 or SAR shall 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 

  

 12 

 
agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Awarded Stock,
notwithstanding the exercise of the Option. The Company shall issue or cause to be issued (and which issuance may be in electronic entry form) 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 17 of the Plan.

an Option in any manner shall decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. Exercise of a SAR in any manner shall, to the
extent the SAR is exercised, result in a decrease in the number of Shares which thereafter shall be available for purposes of the Plan, and the SAR shall cease to be exercisable to the extent it has been exercised. 
 (b)    Termination of Continuous Status as a Service Provider. Upon termination of a Participant’s Continuous Status as a
Service Provider (other than termination by reason of the Participant’s death or Disability), the Participant may exercise his or her Option or SAR within such period of time as is specified in the Award Agreement to the extent that the Award
is vested on the date of termination (but in no event later than the expiration of the term of such Award as set forth in the Award Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for three
(3) months following the Participant’s termination. If the Option or SAR is not so exercised within the time specified herein, the Option or SAR shall terminate, and the Shares covered by such Option or SAR shall revert to the Plan. Unless
otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option or SAR, the Shares covered by the unvested portion of the Option or SAR will revert to the Plan on the date one
(1) month following the Participant’s termination. Notwithstanding the foregoing, in no event shall an Option or SAR be exercisable after the expiration of the term of the Award as provided in the Award Agreement. 
 (c)    Disability of Participant. If a Participant terminates his or her Continuous Status as a Service Provider as a result
of his or her Disability, the Participant may exercise his or her Option or SAR within such period of time as is specified in the Award Agreement to the extent the Option or SAR is vested on the date of termination (but in no event later than the
expiration of the term of such Option or SAR as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option or SAR shall remain exercisable for twelve (12) months following the Participant’s
termination. If, after termination, the Participant does not exercise his or her Option or SAR within the time specified herein, the Option or SAR shall terminate, and the Shares covered by such Option or SAR shall revert to the Plan. Unless
otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option or SAR, the Shares covered by the unvested portion of the Option or SAR will revert to the Plan on the date one
(1) month following the Participant’s termination. Notwithstanding the foregoing, in no event shall an Option or SAR be exercisable after the expiration of the term of the Award as provided in the Award Agreement. 
 (d)    Death of Participant. If a Participant dies while a Service Provider, the Option or SAR may be exercised following the
Participant’s death within such period of time as is specified in the Award Agreement (but in no event may the option be exercised later than the expiration of the 

  

 13 

 
term of such Option or SAR 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 or SAR 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 or SAR shall
remain exercisable for twelve (12) months following Participant’s death. If the Option or SAR is not so exercised within the time specified herein, the Option or SAR shall terminate, and the Shares covered by such Option or SAR shall
revert to the Plan. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option or SAR, the Shares covered by the unvested portion of the Option or SAR will revert to the
Plan on the date one (1) month following the Participant’s termination. Notwithstanding the foregoing, in no event shall an Option or SAR be exercisable after the expiration of the term of the Award as provided in the Award Agreement.

 12.    Restricted Stock. 
 (a)    Grant of Restricted Stock. Subject to the terms and provisions of the Plan (including the limits set forth in Section 7), 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, Shares of Restricted Stock will be held by the Company as escrow agent until the restrictions on such Shares have lapsed.

 (c)    Transferability. Unless determined otherwise by the Administrator, Shares of Restricted Stock 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 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. 
 (i)    General Restrictions. The Administrator may
set restrictions based upon the achievement of Company-wide, departmental, business unit, or individual goals (including, but not limited to, continued employment or service), applicable federal or state securities laws, or any other basis
determined by the Administrator in its discretion. 
 (ii)    Section 162(m) Performance Restrictions. For
purposes of qualifying grants of Restricted Stock as “performance-based compensation” under Section 162(m) of the Code, the Committee, in its discretion, may set restrictions based upon the achievement of Performance Goals. The
Performance Goals shall be set by the Committee on or before the latest date permissible to enable the Restricted Stock to qualify as “performance-based compensation” under 

  

 14 

 
Section 162(m) of the Code. In granting Restricted Stock which is intended to qualify under Section 162(m) of the Code, the Committee shall follow
any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Restricted Stock under Section 162(m) of the Code (e.g., in determining the Performance Goals). 
 (e)    Removal of Restrictions. Except as otherwise provided in this Section 12, 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. 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 entitled to receive all dividends and other distributions paid with respect
to such Shares unless otherwise provided in the Award Agreement. If any such dividends or distributions are paid in Shares, the Shares will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock
with respect to which they were paid. 
 (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. 
 13.    Restricted Stock Units. 
 (a)    Grant.
Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. Each Restricted Stock Unit grant shall be evidenced by an Award Agreement that shall specify such other terms and conditions as the
Administrator, in its sole discretion, shall determine, including all terms, conditions, and restrictions related to the grant, the number of Restricted Stock Units (subject to the limitations set forth in Section 7) and the form of payout,
which, subject to Section 13(d), may be left to the discretion of the Administrator. 
 (b)    Vesting Criteria
and Other Terms. The Administrator shall 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.

 (i)    General Restrictions. The Administrator may set vesting criteria based upon the achievement of
Company-wide, departmental, business unit, or individual goals (including, but not limited to, continued employment or service), applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion.

 (ii)    Section 162(m) Performance Restrictions. For purposes of qualifying grants of Restricted Stock
Units as “performance-based compensation” under Section 162(m) of the Code, the Committee, in its discretion, may set performance objectives based upon the achievement 

  

 15 

 
of Performance Goals. The Performance Goals shall be set by the Committee on or before the latest date permissible to enable the Restricted Stock Units to
qualify as “performance-based compensation” under Section 162(m) of the Code. In granting Restricted Stock Units that are intended to qualify under Section 162(m) of the Code, the Committee shall follow any procedures determined
by it from time to time to be necessary or appropriate to ensure qualification of the Restricted Stock Units under Section 162(m) of the Code (e.g., in determining the Performance Goals). 
 (c)    Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant shall be entitled to
receive a payout as specified in the Award Agreement. 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)    Form and Timing of Payment. Payment of earned Restricted Stock Units shall be made as
soon as practicable after the date(s) set forth in the Award Agreement. The Administrator, in its sole discretion, may pay earned Restricted Stock Units in cash, Shares, or a combination thereof. Shares represented by Restricted Stock Units that are
fully paid in cash again shall be available for grant under the Plan. 
 (e)    Cancellation. On the date set
forth in the Award Agreement, all unearned Restricted Stock Units shall be forfeited to the Company. 
 14.    Performance Shares. 
 (a)    Grant of Performance Shares. Subject to
the terms and conditions of the Plan, Performance Shares may be granted to Service Providers at any time as shall be determined by the Administrator, in its sole discretion. Subject to Section 7 hereof, the Administrator shall have complete
discretion to determine the number of Shares subject to a Performance Share Award granted to any Service Provider. 
 (b)    Value of Performance Shares. 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 objectives in its discretion which,
depending on the extent to which they are met, will determine the number or value of Performance Shares that will be paid out to the Service Providers. Each Award of Performance Shares will be evidenced by an Award Agreement that will specify the
performance period during which the applicable objectives must be met, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 
 (i)    General Restrictions. The Administrator may set performance objective based upon the achievement of Company-wide, departmental, business unit, or individual goals (including, but not
limited to, continued employment or service), applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion. 
  

 16 

 (ii)    Section 162(m) Performance Restrictions. For purposes of
qualifying grants of Performance Shares as “performance-based compensation” under Section 162(m) of the Code, the Committee, in its discretion, may set performance objectives based upon the achievement of Performance Goals. The
Performance Goals shall be set by the Committee on or before the latest date permissible to enable the Performance Shares to qualify as “performance-based compensation” under Section 162(m) of the Code. In granting Performance Shares
that are intended to qualify under Section 162(m) of the Code, the Committee shall follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Performance Shares under
Section 162(m) of the Code (e.g., in determining the Performance Goals). 
 (d)    Earning of Performance
Shares. After the applicable Performance Period has ended, the holder of Performance Shares will be entitled to receive a payout of the number of Performance Shares earned by the Participant over the Performance Period, to be determined as a
function of the extent to which the corresponding performance objectives have been achieved. After the grant of a Performance Share, the Administrator, in its sole discretion, may reduce or waive any performance objectives for such Performance
Share. 
 (e)    Form and Timing of Payment of Performance Shares. Payment of earned Performance Shares will be
made as soon as practicable after the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Performance Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to
the value of the earned Performance Shares at the close of the applicable performance period) or in a combination thereof. 
 (f)    Cancellation of Performance Shares. On the date set forth in the Award Agreement, all unearned or unvested Performance Shares will be forfeited to the Company, and again will be available for grant under
the Plan. 
 15.    Leaves of Absence. Unless the Administrator provides otherwise or except as otherwise required
by Applicable Laws, vesting of Awards granted hereunder shall cease commencing on the first day of any unpaid leave of absence and shall only recommence upon return to active service. 
 16.    Transferability of Awards. Unless determined otherwise by the Administrator or as otherwise provided in the Plan, 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 shall contain such additional terms and conditions as the Administrator deems appropriate. 
 17.    Adjustments Upon Changes in Capitalization, Dissolution, Merger or Change in Control. 
 (a)    Changes in Capitalization. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Award and the number of
shares of Common Stock which have been authorized for issuance under the Plan but 

  

 17 

 
as to which no Awards have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Award, as well as the price per
share, if any, of Common Stock covered by each such outstanding Award and the 162(m) fiscal year share issuance limits under Sections 7(a) and (b) hereof shall, shall be proportionately adjusted for any dividend or other distribution
(whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other
securities of the Company, or other change in the corporate structure of the Company affecting the Shares should the Committee (in its sole discretion) determine such an adjustment to be appropriate in order to prevent dilution or enlargement of the
benefits or potential benefits intended to be made available under the Plan. Such adjustment shall be made by the Board or the Committee, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided
herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common
Stock subject to an Award. 
 (b)    Dissolution or Liquidation. In the event of the proposed dissolution or
liquidation of the Company, all outstanding Awards will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Administrator. The Administrator in its discretion may provide for a Participant to
have the right to exercise his or her Option, SAR or right to purchase Restricted Stock until ten (10) days prior to such transaction as to all of the Awarded Stock covered thereby, including Shares as to which the Award would not otherwise be
exercisable. In addition, the Administrator may provide that any Company repurchase option or forfeiture rights applicable to any Award shall lapse 100%, and that any Award vesting shall accelerate 100%, provided the proposed dissolution or
liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously exercised (with respect to Options, SARs and right to purchase Restricted Stock) or vested (with respect to other Awards), an Award will
terminate immediately prior to the consummation of such proposed action. 
 (c)    Merger or Change in Control. In
the event of a merger or Change in Control, each outstanding Award shall be assumed or an equivalent award substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation
refuses to assume or substitute for the Award, the Participant shall (i) fully vest in and have the right to exercise the Option, SAR or right to purchase Restricted Stock as to all of the Awarded Stock, including Shares as to which it would
not otherwise be vested or exercisable, and (ii) fully earn and receive a payout with respect to other Awards. If an Award is not assumed or substituted for in the event of a merger or Change in Control, the Administrator shall notify the
Participant in writing or electronically that (i) the Option, SAR or right to purchase Restricted Stock shall be fully vested and exercisable for a period of fifteen (15) days from the date of such notice, and (ii) all outstanding
Options, SARs and rights to purchase Restricted Stock shall terminate upon the expiration of such period and (iii) all other outstanding Awards shall be paid out immediately prior to the merger or Change in Control. For the purposes of this
paragraph, the Award shall be considered assumed if, following the merger or Change in Control, the assumed Award confers the right to purchase or receive, for each Share of Awarded Stock subject to the Award immediately prior to the merger or
Change in Control, the consideration (whether stock, cash, or other securities or property) received in the merger or Change in Control by holders of Common Stock for each 

  

 18 

 
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 merger or 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 (or payout or vesting, as applicable) of the Award, for each Share of Awarded Stock subject to the 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 merger or Change in Control. 
 18.    Date of Grant. The date of grant of an Award shall 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 shall be provided to each Participant within a reasonable time after the date of such grant. 
 19.    Amendment and Termination of the Plan. 
 (a)    Amendment and
Termination. The Board may at any time amend, alter, suspend or terminate the Plan. 
 (b)    Shareholder
Approval. The Plan will be subject to approval by the shareholders of the Company within twelve (12) months after the date the Plan is adopted. Such shareholder approval will be obtained in the manner and to the degree required under
Applicable Laws. The Company shall obtain shareholder 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 shall impair the rights of any Participant, unless mutually agreed otherwise
between the Participant and the Administrator, which agreement must be in writing (or electronic format) and signed by the Participant and the Company. Termination of the Plan shall 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
shall not be issued pursuant to the exercise or payout, as applicable, of an Award unless the exercise or payout, as applicable, of such Award and the issuance and delivery of such Shares shall comply with Applicable Laws and shall 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 or payout, as applicable, of an Award, the Company may require the person exercising such Option, SAR or right to purchase Restricted Stock, or in the case of another Award, the person receiving
the payout, 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. 
  

 19 

 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 counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the
failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. 
 22.    Severability. Notwithstanding any contrary provision of the Plan or an Award to the contrary, if any one or more of the provisions (or any part thereof) of this Plan or the Awards shall be held invalid,
illegal or unenforceable in any respect, such provision shall be modified so as to make it valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions (or any part thereof) of the Plan or Award, as
applicable, shall not in any way be affected or impaired thereby. 
 23.    Shareholder Approval. Subject to
Section 19 of the Plan, the Plan will become effective upon its adoption by the Board. It will continue in effect for a term of five (5) years from the date of approval by the shareholders of the Company unless terminated earlier under
Section 19 of the Plan. 
 24.    Non-U.S. Employees. Notwithstanding anything in the Plan to the contrary,
with respect to any employee who is resident outside of the United States, the Administrator may, in its sole discretion, amend the terms of the Plan in order to conform such terms to the requirements of local law or to meet the objectives of the
Plan. The Administrator may, where appropriate, establish one or more sub-plans for this purpose. 
  

 20Loan and Security Agreement

 Exhibit 10.5 
 LOAN AND SECURITY AGREEMENT 

 This LOAN AND SECURITY AGREEMENT is entered into as of February 14, 2007, by and between Comerica
Bank (“Bank”), Nanometrics Incorporated (“Borrower”), Accent Optical Technologies Nanometrics, Inc. (“Accent”) and Nanometrics IVS Division, Inc., (“IVS”, and with Accent, each individually a
“Guarantor”, and together, collectively, jointly and severally “Guarantors”). 
 RECITALS 
 Borrower wishes to obtain credit from time to time from Bank, and Bank desires to extend credit to Borrower. This Agreement sets forth the terms on which
Bank will advance credit to Borrower, and Borrower will repay the amounts owing to Bank. 
 Each Guarantor is affiliated with Borrower and
will derive direct and indirect benefits from Bank’s extension of credit to Borrower. Each Guarantor, in order to induce Bank to extend credit to Borrower, and in order to secure such Guarantor’s obligations to Bank under the Loan
Documents, hereby agrees to enter into this Agreement. 
 AGREEMENT 
 The parties agree as follows: 
  

	 	1.	DEFINITIONS AND CONSTRUCTION. 

 1.1
Definitions. As used in this Agreement, all capitalized terms shall have the definitions set forth on Exhibit A. Any term used in the Code and not defined herein shall have the meaning given to the term in the Code. 
 1.2 Accounting Terms. Any accounting term not specifically defined on Exhibit A shall be construed in accordance with GAAP and all calculations
shall be made in accordance with GAAP. The term “financial statements” shall include the accompanying notes and schedules. 
  

	 	2.	LOAN AND TERMS OF PAYMENT. 

 2.1 Credit
Extensions. 
 (a) Promise to Pay. Borrower promises to pay to Bank, in lawful money of the United States of America, or such
Alternative Currency as may be applicable hereunder from time to time, the aggregate unpaid principal amount of all Credit Extensions made by Bank to Borrower, together with interest on the unpaid principal amount of such Credit Extensions at rates
in accordance with the terms hereof. 
 (b) Advances Under Revolving Line. 
 (i) Amount. Subject to and upon the terms and conditions of this Agreement (1) Borrower may request Advances so long as the Outstanding
Utilization does not exceed the lesser of (A) the Revolving Line, or (B) $7,500,000 plus the Borrowing Base, and (2) amounts borrowed pursuant to this Section 2.1(b) may be repaid and reborrowed at any time prior to the Revolving
Maturity Date, at which time all Advances under this Section 2.1(b) shall be immediately due and payable. Borrower may prepay any Advances without penalty or premium. 
 (ii) Form of Request. Whenever Borrower desires a U.S. Base Rate Advance, Borrower will notify Bank by facsimile transmission or telephone no
later than 3:00 p.m. Pacific time (1:00 p.m. Pacific time for wire transfers), on the Business Day that the Advance is to be made. Each such notification shall be promptly confirmed by a Payment/Advance Form in substantially the form of
Exhibit C. Requests for all Advances, other than U.S. Base Rate Advances, shall be made in accordance with the requirements of the Interest Rate Addendum and promptly confirmed by a Payment/Advance Form in substantially the form of

 
Exhibit C. Bank is authorized to make Advances under this Agreement, based upon instructions received from a Responsible Officer or a designee of
a Responsible Officer, or without instructions if in Bank’s discretion such Advances are necessary to meet Obligations which have become due and remain unpaid. Bank shall be entitled to rely on any telephonic notice given by a person who Bank
reasonably believes to be a Responsible Officer or a designee thereof, and Borrower shall indemnify and hold Bank harmless for any damages or loss suffered by Bank as a result of such reliance. Bank will credit the amount of Advances made under this
Section 2.1(b) to Borrower’s deposit account. 
 (iii) Letter of Credit Sublimit. Subject to the availability under the
Revolving Line, and in reliance on the representations and warranties of Borrower set forth herein, at any time and from time to time from the date hereof through the Business Day immediately prior to the Revolving Maturity Date, Bank shall issue
for the account of Borrower such Letters of Credit as Borrower may request by delivering to Bank a duly executed letter of credit application on Bank’s standard form; provided, however, that the outstanding and undrawn amounts
under all such Letters of Credit (i) shall not at any time exceed the Letter of Credit Sublimit, and (ii) shall be subtracted from the Revolving Line, or the Borrowing Base, as applicable, in the same manner as U.S. Dollar Advances.
If any term of in the letter of credit application on Bank’s standard form conflicts with this Agreement, this Agreement shall govern. Any drawn but unreimbursed amounts under any Letters of Credit shall be charged as U.S. Base Rate Advances
against the Revolving Line. All Letters of Credit shall be in form and substance acceptable to Bank in its sole discretion and shall be subject to the terms and conditions of Bank’s form application and letter of credit agreement. Borrower will
pay any standard issuance and other fees that Bank notifies Borrower it will charge for issuing and processing Letters of Credit. 
 (iv)
Credit Card Services Sublimit. Subject to the terms and conditions of this Agreement, Borrower may request corporate credit cards and standard and e-commerce merchant account services from Bank (collectively, the “Credit Card
Services”). The aggregate limit of the corporate credit cards and merchant credit card processing reserves shall not exceed the Credit Card Services Sublimit, provided that availability under the Revolving Line shall be reduced by the aggregate
limits of the corporate credit cards issued to Borrower and merchant credit card processing reserves. In addition, Bank may, in its sole discretion, charge as U.S. Base Rate Advances any amounts that become due or owing to Bank in connection with
the Credit Card Services. The terms and conditions (including repayment and fees) of such Credit Card Services shall be subject to the terms and conditions of the Bank’s standard forms of application and agreement for the Credit Card Services,
which Borrower hereby agrees to execute. 
 (v) Foreign Exchange Sublimit. Subject to and upon the terms and conditions of this
Agreement (including but not limited to availability under the Revolving Line) and any other agreement that Borrower may enter into with Bank in connection with foreign exchange transactions (“Foreign Exchange Contracts”), Borrower may
request Bank to enter into Foreign Exchange Contracts with Borrower due not later than the Revolving Maturity Date. Borrower shall pay any standard issuance and other fees that Bank notifies Borrower will be charged for issuing and processing
Foreign Exchange Contracts for Borrower. The “FX Amount” shall equal the amount determined by multiplying (i) the aggregate amount, in United States Dollars, of FX Contracts between Borrower and Bank remaining outstanding as of any
date of determination by (ii) the applicable Foreign Exchange Reserve Percentage as of such date. The Foreign Exchange Reserve Percentage shall be ten percent (10%). The aggregate FX Amount outstanding at any time may not exceed the Foreign
Exchange Sublimit. 
 (vi) Collateralization of Obligations Extending Beyond Maturity. If Borrower has not secured to Bank’s
satisfaction its obligations with respect to any Letters of Credit, Credit Card Services, or Foreign Exchange Contracts by the Revolving Maturity Date, then, effective as of such date, the balance in any deposit accounts held by Bank and the
certificates of deposit or time deposit accounts issued by Bank in Borrower’s name (and any interest paid thereon or proceeds thereof, including any amounts payable upon the maturity or liquidation of such certificates or accounts), shall
automatically secure such obligations to the extent of the then continuing or outstanding and undrawn Letters of Credit, Credit Card Services, or Foreign Exchange Contracts. Borrower authorizes Bank to hold such balances in pledge and to decline to
honor any drafts thereon or any requests by Borrower or any other Person to pay or otherwise transfer any part of such balances for so long as the Letters of Credit, Credit Card Services, or Foreign Exchange Contracts are outstanding or continue.

 2.2 Overadvances. If at any time the Outstanding Utilization exceeds the lesser of (A) the
Revolving Line, or (B) $7,500,000 plus the Borrowing Base, Borrower shall immediately pay to Bank, in cash, the amount of such excess. 
 2.3 Interest Rates, Payments, and Calculations. 
 (a) Interest Rates. 
 (i) Advances. Except as set forth in Section 2.3(b), the Advances shall bear interest, on the outstanding daily balance thereof, as set forth
in the Interest Rate Addendum. 
 (b) Default Rate. All Obligations shall bear interest, from and after the occurrence and during the
continuance of an Event of Default, at a rate equal to 3 percentage points above the interest rate applicable immediately prior to the occurrence of the Event of Default. 
 (c) Payments. Interest for U.S. Base Rate Advances hereunder shall be due and payable on the first Business Day of each month during the term
hereof. Interest for all other Advances shall be due and payable on the last day of the applicable interest period in the same currency such Advance was originally funded. Bank shall, at its option, charge such interest, all Bank Expenses, and all
Periodic Payments against any of Borrower’s deposit accounts or against the Revolving Line, in which case those amounts shall thereafter accrue interest at the rate then applicable hereunder. Any interest not paid when due shall be compounded
by becoming a part of the Obligations, and such interest shall thereafter accrue interest at the rate then applicable hereunder. In the event any charges related to Alternative Currency Advances, payable in an Alternative Currency, are made by Bank
against the Revolving Line at any time, such charges will be made in an amount equal to the U.S. Dollar Equivalent as of the date of such charges. 
 (d) Repayment. The principal amount of each Advance other than U.S. Base Rate Advances shall be due and payable at the end of the interest period applicable to such Advance pursuant to the Interest Rate
Addendum. Each Alternative Currency Advance shall be payable in the same currency such Advance was originally funded. 
 (e)
Computation. In the event the Prime Rate is changed from time to time hereafter, the applicable rate of interest hereunder shall be increased or decreased, effective as of the day the Prime Rate is changed, by an amount equal to such change
in the Prime Rate. All interest chargeable under the Loan Documents shall be computed on the basis of a 360 day year for the actual number of days elapsed. 
 (f) Time. All payments by Borrower of principal of, or interest, or of fees, shall be made without setoff or counterclaim on the date specified for payment under this Agreement not later than 1:00 p.m. (Eastern
Time) in immediately available funds to Bank. 
 2.4 Crediting Payments. Prior to the occurrence and while no Event of Default is
continuing, Bank shall credit a wire transfer of funds, check or other item of payment to such deposit account or Obligation as Borrower specifies. After the occurrence of an Event of Default and while it is continuing, Bank shall have the right, in
its sole discretion, to immediately apply any wire transfer of funds, check, or other item of payment Bank may receive to conditionally reduce Obligations, but such applications of funds shall not be considered a payment on account unless such
payment is of immediately available federal funds or unless and until such check or other item of payment is honored when presented for payment. Notwithstanding anything to the contrary contained herein, any wire transfer or payment received by Bank
after 12:00 noon Pacific time shall be deemed to have been received by Bank as of the opening of business on the immediately following Business Day. Except as provided in the Interest Rate Addendum, whenever any payment to Bank under the Loan
Documents would otherwise be due (except by reason of acceleration) on a date that is not a Business Day, such payment shall instead be due on the next Business Day, and additional fees or interest, as the case may be, shall accrue and be payable
for the period of such extension. 

 2.5 Fees. Borrower shall pay to Bank the following: 
 (a) Facility Fee. A fee equal to $10,000, which shall be nonrefundable and which Bank acknowledges receipt of prior to the Closing Date;

 (b) Unused Revolving Line Fee. On the first Business Day of each month commencing on the first Business Day of the month following
the Closing Date and until and on the Revolving Maturity Date, an unused revolving line commitment fee in an amount equal to 0.25% per annum times the result of (i) the Revolving Line, less (ii) the average daily outstanding
balance for the aggregate U.S. Dollar Advances and the U.S. Dollar Equivalent of all Alternative Currency Advances during the Measurement Period. “Measurement Period” means the period from the first day of the previous month (or
from the Closing Date if the Closing Date occurred in such previous month or from the first day of the month in which the Revolving Maturity Date occurs if they fee is being paid on the Revolving Maturity Date) through the last day of the previous
month (or through the Revolving Maturity Date if the fee is being paid on the Revolving Maturity Date). 
 (c) Bank Expenses. On the
Closing Date, all Bank Expenses incurred through the Closing Date, and, after the Closing Date, all Bank Expenses, as and when they become due. 
 2.6 Term. This Agreement shall become effective on the Closing Date and, subject to Section 13.7, shall continue in full force and effect for so long as any Obligations remain outstanding or Bank has any obligation to make
Credit Extensions under this Agreement. Notwithstanding the foregoing, Bank shall have the right to terminate its obligation to make Credit Extensions under this Agreement immediately and without notice upon the occurrence and during the continuance
of an Event of Default.

 (c) an

 (l) current Compliance Certificate in

 (m) such other documents or certificates, and completion of such other matters, as Bank may reasonably

true, correct and complete in all material respects as of such date). The making of each Credit Extension shall be deemed to be a representation and warranty by Borrower on the date of such Credit Extension as to the accuracy of the facts referred
to in this Section 3.2. 
  

	 	4.	CREATION OF SECURITY INTEREST. 

 4.1 Grant of
Security Interest. Borrower and each Guarantor grants and pledges to Bank a continuing security interest in the Collateral to secure prompt repayment of any and all Obligations and to secure prompt performance by Borrower and each Guarantor of
each of its respective covenants and duties under the Loan Documents (i.e., the Collateral of each Guarantor secures its Obligations under its Guaranty). Except as set forth in the Schedule and except for the Permitted Liens, such security interest
constitutes a valid, security interest in the presently existing Collateral, and will constitute a valid security interest in later-acquired Collateral (and shall constitute a first priority perfected security interest to the extent that a security
interest therein may be perfected by the filing of a financing statement with the Delaware Secretary of State). Notwithstanding any termination, Bank’s Lien on the Collateral shall remain in effect for so long as any Obligations are
outstanding. Notwithstanding anything to the contrary herein, the term “Collateral” shall not include any rights or interest in any personal property (including Equipment) to the extent that: (i) such personal property constitutes
collateral for Permitted Indebtedness and (ii) under the terms of the applicable loan agreement, lease, or other contract with respect thereto, the valid grant of a security interest or lien therein to Bank is prohibited under the terms of such
loan agreement, lease, or other contract (including where the violation of any such prohibition would result in the termination of the applicable contract) and such prohibition has not been or is not waived or the consent of the other party to such
loan agreement, lease, or other contract has not been obtained. Bank agrees to execute any UCC termination statements or other instruments necessary to release its security interest with respect to any such personal property or equipment financed by
a third party. 
 4.2 Perfection of Security Interest. Borrower and each Guarantor authorizes Bank to file at any time financing
statements, continuation statements, and amendments thereto that (i) either specifically describe the Collateral or describe the Collateral as all assets of Borrower or such Guarantor of the kind pledged hereunder, and (ii) contain any
other information required by the Code for the sufficiency of filing office acceptance of any financing statement, continuation statement, or amendment, including whether Borrower or such Guarantor is an organization, the type of organization and
any organizational identification number issued to Borrower or such Guarantor, if applicable. Any such financing statements may be signed by Bank on behalf of Borrower or any Guarantor, as provided in the Code, and may be filed at any time in any
jurisdiction whether or not Revised Article 9 of the Code is then in effect in that jurisdiction. Borrower and each Guarantor shall from time to time endorse and 

 
deliver to Bank, at the request of Bank, all Negotiable Collateral and other documents that Bank may reasonably request, in form satisfactory to Bank, to
perfect and continue perfected Bank’s security interests in the Collateral and in order to fully consummate all of the transactions contemplated under the Loan Documents. Borrower and each Guarantor shall have possession of the Collateral,
except where expressly otherwise provided in this Agreement or where Bank chooses to perfect its security interest by possession in addition to the filing of a financing statement. Where Collateral is in possession of a third party bailee, Borrower
or Guarantors shall take such steps as Bank reasonably requests for Bank to (i) obtain an acknowledgment, in form and substance satisfactory to Bank, of the bailee that the bailee holds such Collateral for the benefit of Bank, (ii) obtain
“control” of any Collateral consisting of investment property, deposit accounts, letter-of-credit rights or electronic chattel paper (as such items and the term “control” are defined in Revised Article 9 of the Code) by causing
the securities intermediary or depositary institution or issuing bank to execute a control agreement in form and substance satisfactory to Bank. Borrower and Guarantors will not create any chattel paper without placing a legend on the chattel paper
acceptable to Bank indicating that Bank has a security interest in the chattel paper. Borrower or Guarantors from time to time may deposit with Bank specific cash collateral to secure specific Obligations; Borrower and each Guarantor authorizes Bank
to hold such specific balances in pledge and to decline to honor any drafts thereon or any request by Borrower or such Guarantor or any other Person to pay or otherwise transfer any part of such balances for so long as the specific Obligations are
outstanding. 
 4.3 Right to Inspect. Bank (through any of its officers, employees, or agents) shall have the right, upon reasonable
prior notice, from time to time during Borrower’s or any Guarantor’s usual business hours but no more than twice a year (unless an Event of Default has occurred and is continuing), to inspect Borrower’s or such Guarantor’s Books
and to make copies thereof and to check, test, and appraise the Collateral in order to verify Borrower’s and Guarantors’ financial condition or the amount, condition of, or any other matter relating to, the Collateral. 
  

	 	5.	REPRESENTATIONS AND WARRANTIES. 

 Borrower
represents and warrants as follows: 
 5.1 Due Organization and Qualification. Borrower and each Subsidiary is a corporation duly
existing under the laws of the state in which it is incorporated and qualified and licensed to do business in any state in which the conduct of its business or its ownership of property requires that it be so qualified, except where the failure to
do so would not reasonably be expected to cause a Material Adverse Effect. 
 5.2 Due Authorization; No Conflict. The execution,
delivery, and performance of the Loan Documents are within Borrower’s powers, have been duly authorized, and are not in conflict with nor constitute a breach of any provision contained in Borrower’s Articles/Certificate of Incorporation or
Bylaws, nor will they constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement by which it is bound, except to the extent such default would not reasonably be expected to
cause a Material Adverse Effect. 
 5.3 Collateral. Borrower has rights in or the power to transfer the Collateral, and its title to
the Collateral is free and clear of Liens, adverse claims, and restrictions on transfer or pledge except for Permitted Liens. Except (i) as set forth in the Schedule, (ii) for inventory in transit or located at customer sites or contract

Certificate as an Eligible Account. All Inventory is in all material respects of good and merchantable quality, free from all material defects, except for Inventory for which adequate reserves have been made. Except as set forth in the Schedule and
as permitted by Section 6.7, none of the Collateral consisting of deposit accounts or investment property is maintained with a Person other than Bank or Bank’s Affiliates. 

 5.4 Intellectual Property. Borrower is the sole owner of the Intellectual Property, except for
(i) licenses granted by Borrower in the ordinary course of business, and (ii) jointly-developed Intellectual Property that is co-owned with other parties. To the best of Borrower’s knowledge, each of the Copyrights, Trademarks and
Patents is valid and enforceable, and no part of the Intellectual Property has been judged invalid or unenforceable, in whole or in part, and no claim has been made to Borrower that any part of the Intellectual Property violates the rights of any
third party except to the extent such claim would not reasonably be expected to cause a Material Adverse Effect. 
 5.5 Name; Location of
Chief Executive Office. Except as disclosed in the Schedule or as disclosed to Bank pursuant to Section 7.2, Borrower has not done business under any name other than that specified on the signature page hereof, and its exact legal name as

Section 10 hereof. 
 5.6 Litigation. Except as set forth in the Schedule and in Borrower’s filings with the
Securities and Exchange Commission, there are no actions or proceedings pending by or against Borrower or any Subsidiary before any court or administrative agency in which a likely adverse decision would reasonably be expected to have a Material
Adverse Effect. 
 5.7 No Material Adverse Change in Financial Statements. All consolidated and consolidating financial statements
related to Borrower and any Subsidiary that are delivered by Borrower to Bank fairly present in all material respects Borrower’s consolidated and consolidating financial condition as of the date thereof and Borrower’s consolidated and
consolidating results of operations for the period then ended. There has not been a material adverse change in the consolidated financial condition of Borrower since the date of the most recent of such financial statements submitted to Bank.

 5.8 Solvency, Payment of Debts. Borrower is able to pay its debts (including trade debts) as they mature; the fair saleable value
of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; and Borrower is not left with unreasonably small capital after the transactions contemplated by this Agreement. 
 5.9 Compliance with Laws and Regulations. Borrower and each Subsidiary have met the minimum funding requirements of ERISA with respect to any
employee benefit plans subject to ERISA. No event has occurred resulting from Borrower’s failure to comply with ERISA that is reasonably likely to result in Borrower’s incurring any liability that could have a Material Adverse Effect.
Borrower is not an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940. Borrower is not engaged principally, or as one of the important
activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulations T and U of the Board of Governors of the Federal Reserve System). Borrower has complied in all material
respects with all the provisions of the Federal Fair Labor Standards Act. Borrower is in compliance with all environmental laws, regulations and ordinances except where the failure to comply is not reasonably likely to have a Material Adverse
Effect. Borrower has not violated any statutes, laws, ordinances or rules applicable to it, the violation of which could reasonably be expected to have a Material Adverse Effect. Borrower and each Subsidiary have filed or caused to be filed all tax
returns required to be filed, and have paid, or have made adequate provision for the payment of, all taxes reflected therein except those being contested in good faith with adequate reserves under GAAP or where the failure to file such returns or
pay such taxes would not reasonably be expected to have a Material Adverse Effect. 
 5.10 Subsidiaries. Borrower does not own any
stock, partnership interest or other equity securities of any Person, except for Permitted Investments. 
 5.11 Government Consents.
Borrower and each Subsidiary have obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all governmental authorities that are necessary for the continued operation of Borrower’s
business as currently conducted, except where the failure to do so would not reasonably be expected to cause a Material Adverse Effect. 

 5.12 Inbound Licenses. Except as disclosed on the Schedule or where any prohibition or restriction
would not be effective to prevent the granting of a security interest under applicable law, Borrower is not a party to, nor is bound by, any license or other agreement that prohibits or otherwise restricts Borrower from granting a security interest
in Borrower’s interest in such license or agreement or any other property. 
 5.13 Full Disclosure. No representation, warranty
or other statement made by Borrower in any certificate or written statement furnished to Bank taken together with all such certificates and written statements furnished to Bank contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained in such certificates or statements not misleading, it being recognized by Bank that the projections and forecasts provided by Borrower in good faith and based upon reasonable
assumptions are not to be viewed as facts and that actual results during the period or periods covered by any such projections and forecasts may differ from the projected or forecasted results.

 6.1 Good Standing and Government Compliance. Borrower shall maintain its and each of its Subsidiaries’ corporate existence and good standing

 (a)
Borrower, at its expense, shall keep the Collateral insured against loss or damage by fire, theft, explosion, sprinklers, and all other hazards and risks, and in such amounts, as ordinarily insured against by other owners in similar businesses

employees of Borrower and its Subsidiaries entered into in the ordinary course of business. 
 7.9 Subordinated Debt. Make any payment
in respect of any Subordinated Debt, or permit any of its Subsidiaries to make any such payment, except in compliance with the terms of such Subordinated Debt, or amend any provision adversely affecting Bank’s rights contained in any
documentation relating to the Subordinated Debt without Bank’s prior written consent. 
 7.10 Inventory and Equipment. Except
with respect to inventory in transit, at a customer location or at a contract manufacturer, store the Inventory or the Equipment with a value in excess of $250,000, with a bailee, warehouseman, or similar third party located unless the third party
has been notified of Bank’s security interest and Bank (a) has received an acknowledgment from the third party that it is holding or will hold the Inventory or Equipment for Bank’s benefit or (b) is in possession of the warehouse
receipt, where negotiable, covering such Inventory or Equipment. Except for Inventory sold in the ordinary course of business or that is located at the locations specified in the previous sentence and except for such other locations as Bank may
approve in writing or locations outside the United States, Borrower shall keep the Inventory and Equipment only at the location set forth in Section 10 and such other locations of which Borrower gives Bank prior written notice.

Company Act of 1940, or become principally engaged in, or undertake as one of its important activities, the business of extending credit for the purpose of purchasing or carrying margin stock, or use the proceeds of any Credit Extension for such
purpose. 
  

	 	8.	EVENTS OF DEFAULT. 

 Any one or more of the
following events shall constitute an Event of Default by Borrower and Guarantors under this Agreement: 
 8.1 Payment Default. If
Borrower fails to pay any principal or interest within three days of when due or any other the Obligations within 30 days of receipt of an invoice therefor; 
 8.2 Covenant Default. 
 (a) If Borrower fails to perform any obligation under Section 6.2, 6.5,
6.6 or 6.7 or violates any of the covenants contained in Article 7 of this Agreement; or

observe any other material term, provision, condition, covenant contained in this Agreement, in any of the Loan Documents, or in any other present or future agreement between Borrower and Bank and as to any default under such other term, provision,
condition or covenant that can be cured, has failed to cure such default within 10 days after Borrower receives notice thereof or any officer of Borrower becomes aware thereof; provided, however, that if the default cannot by its nature be cured
within the 10 day period or cannot after diligent attempts by Borrower be cured within such 10 day period, and such 

 
default is likely to be cured within a reasonable time, then Borrower shall have an additional reasonable period (which shall not in any case exceed 30 days)
to attempt to cure such default, and within such reasonable time period the failure to have cured such default shall not be deemed an Event of Default but no Credit Extensions will be made; 
 8.3 Intentionally Omitted. 
 8.4
Material Adverse Change. If there is a material impairment in the prospect of repayment of any portion of the Obligations or a material impairment in the perfection, value or priority of Bank’s security interests in the Collateral;

is levied upon, or comes into the possession of any trustee, receiver or person acting in a similar capacity and such attachment, seizure, writ or distress warrant or levy has not been removed, discharged or rescinded within 10 days, or if Borrower
is enjoined, restrained, or in any way prevented by court order from continuing to conduct all or any material part of its business affairs and such court order has not been released within 10 days, or if a judgment or other claim becomes a lien or
encumbrance upon any material portion of Borrower’s assets and such lien or encumbrance has not been released within 10 days, or if a notice of lien, levy, or assessment is filed of record with respect to any of Borrower’s assets by the
United States Government, or any department, agency, or instrumentality thereof, or by any state, county, municipal, or governmental agency, and the same is not paid or disputed within ten days after Borrower receives notice thereof, provided that
none of the foregoing shall constitute an Event of Default where such action or event is stayed or an adequate bond has been posted pending a good faith contest by Borrower (provided that no Credit Extensions will be made during such cure period);

 8.6 Insolvency. If an Insolvency Proceeding is commenced by Borrower, or if an Insolvency Proceeding is commenced against Borrower
and is not dismissed or stayed within 45 days (provided that no Credit Extensions will be made prior to the dismissal of such Insolvency Proceeding); 
 8.7 Other Agreements. If there is a default or other failure to perform in any agreement to which Borrower is a party with a third party or parties resulting in a right by such third party or parties, whether
or not exercised, to accelerate the maturity of any Indebtedness in an amount in excess of $1,000,000; 
 8.8 Subordinated Debt. If

Guaranty ceases for any reason to be in full force and effect, or any Guarantor fails to perform any obligation under any Guaranty, the Stock Pledge Agreement or this Agreement (collectively, the “Guaranty Documents”), or any event of
default occurs under any Guaranty Document or any Guarantor revokes or purports to revoke a Guaranty, or any material misrepresentation or material misstatement exists now or hereafter in any warranty or representation set forth in any Guaranty
Document or in any certificate delivered to Bank in connection with any Guaranty Document, or if any of the circumstances described in Sections 8.2 through 8.10 occur with respect to any Guarantor, or if the representations and warranties made with
respect to Borrower in Article 5 are not true with respect to any Guarantor, or if any Guarantor fails to comply with Sections 6.1, 6.3 through 6.6, 6.8 through 6.10, and 7.1 through 7.11, to the fullest extent possible as if it were the Borrower
thereunder. 

	 	9.	BANK’S RIGHTS AND REMEDIES. 

 9.1 Rights and
Remedies. Upon the occurrence and during the continuance of an Event of Default, Bank may, at its election, without notice of its election and without demand, do any one or more of the following, all of which are authorized by Borrower:

 (a) Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in Section 8.6, all Obligations shall become immediately due and payable without any action by Bank); 
 (b) Demand that Borrower (i) deposit cash with Bank in an amount equal to the amount of any Letters of Credit remaining undrawn, as collateral
security for the repayment of any future drawings under such Letters of Credit, and (ii) pay in advance all Letter of Credit fees scheduled to be paid or payable over the remaining term of the Letters of Credit, and Borrower shall promptly
deposit and pay such amounts; 
 (c) Cease advancing money or extending credit to or for the benefit of Borrower under this Agreement or
under any other agreement between Borrower and Bank; 
 (d) Settle or adjust disputes and claims directly with account debtors for amounts,
upon terms and in whatever order that Bank reasonably considers advisable; 
 (e) Make such payments and do such acts as Bank considers
necessary or reasonable to protect its security interest in the Collateral. Borrower agrees to assemble the Collateral if Bank so requires, and to make the Collateral available to Bank as Bank may designate. Borrower authorizes Bank to enter the
premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any encumbrance, charge, or lien which in Bank’s determination appears to be prior or
superior to its security interest and to pay all expenses incurred in connection therewith. With respect to any of Borrower’s owned premises, Borrower hereby grants Bank a license to enter into possession of such premises and to occupy the
same, without charge, in order to exercise any of Bank’s rights or remedies provided herein, at law, in equity, or otherwise; 
 (f)
Set off and apply to the Obligations any and all (i) balances and deposits of Borrower held by Bank, and (ii) indebtedness at any time owing to or for the credit or the account of Borrower held by Bank; 
 (g) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the
Collateral. Bank is hereby granted a license or other right, solely pursuant to the provisions of this Section 9.1, to use, without charge, Borrower’s labels, patents, copyrights, rights of use of any name, trade secrets, trade
names, trademarks, service marks, and advertising matter, or any property of a similar nature, as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Bank’s
exercise of its rights under this Section 9.1, Borrower’s rights under all licenses and all franchise agreements shall inure to Bank’s benefit; 
 (h) Sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Borrower’s premises) as
Bank determines is commercially reasonable, and apply any proceeds to the Obligations in whatever manner or order Bank deems appropriate. Bank may sell the Collateral without giving any warranties as to the Collateral. Bank may specifically disclaim
any warranties of title or the like. This procedure will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral. If Bank sells any of the Collateral upon credit, Borrower will be credited only with payments
actually made by the purchaser, received by Bank, and applied to the indebtedness of the purchaser. If the purchaser fails to pay for the Collateral, Bank may resell the Collateral and Borrower shall be credited with the proceeds of the sale;

 (i) Bank may credit bid and purchase at any public sale; 
 (j) Apply for the appointment of a receiver, trustee, liquidator or conservator of the Collateral, without notice and without regard to the adequacy of
the security for the Obligations and without regard to the solvency of Borrower, any guarantor or any other Person liable for any of the Obligations; and 
 (k) Any deficiency that exists after disposition of the Collateral as provided above will be paid immediately by Borrower. 
 Bank may comply with any applicable state or federal law requirements in connection with a disposition of the Collateral and compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral.

 9.2 Power of Attorney. Effective only upon the occurrence and during the continuance of an Event of Default, Borrower hereby
irrevocably appoints Bank (and any of Bank’s designated officers, or employees) as Borrower’s true and lawful attorney to: (a) send requests for verification of Accounts or notify account debtors of Bank’s security interest in
the Accounts; (b) endorse Borrower’s name on any checks or other forms of payment or security that may come into Bank’s possession; (c) sign Borrower’s name on any invoice or bill of lading relating to any Account, drafts
against account debtors, schedules and assignments of Accounts, verifications of Accounts, and notices to account debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all claims under and decisions with respect to
Borrower’s policies of insurance; (f) settle and adjust disputes and claims respecting the accounts directly with account debtors, for amounts and upon terms which Bank determines to be reasonable; (g) to modify, in its sole
discretion, any intellectual property security agreement entered into between Borrower and Bank without first obtaining Borrower’s approval of or signature to such modification by amending Exhibits A, B, and C, thereof, as
appropriate, to include reference to any right, title or interest in any Copyrights, Patents or Trademarks acquired by Borrower after the execution hereof or to delete any reference to any right, title or interest in any Copyrights, Patents or
Trademarks in which Borrower no longer has or claims to have any right, title or interest; and (h) to file, in its sole discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral
without the signature of Borrower where permitted by law; provided Bank may exercise such power of attorney to sign the name of Borrower on any of the documents described in clauses (g) and (h) above, regardless of whether an Event of
Default has occurred. The appointment of Bank as Borrower’s attorney in fact, and each and every one of Bank’s rights and powers, being coupled with an interest, is irrevocable until all of the Obligations have been fully repaid and
performed and Bank’s obligation to provide advances hereunder is terminated. 
 9.3 Accounts Collection. At any time after the
occurrence and during the continuation of an Event of Default, Bank may notify any Person owing funds to Borrower of Bank’s security interest in such funds and verify the amount of such Account. Borrower shall collect all amounts owing to
Borrower for Bank, receive in trust all payments as Bank’s trustee, and immediately deliver such payments to Bank in their original form as received from the account debtor, with proper endorsements for deposit. 
 9.4 Bank Expenses. If Borrower fails to pay any amounts or furnish any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the following after reasonable notice to Borrower: (a) make payment of the same or any part thereof; (b) set up such reserves under the Revolving Line as Bank deems
necessary to protect Bank from the exposure created by such failure; or (c) obtain and maintain insurance policies of the type discussed in Section 6.5 of this Agreement, and take any action with respect to such policies as Bank
deems prudent. Any amounts so paid or deposited by Bank shall constitute Bank Expenses, shall be immediately due and payable, and shall bear interest at the then applicable rate hereinabove provided, and shall be secured by the Collateral. Any
payments made by Bank shall not constitute an agreement by Bank to make similar payments in the future or a waiver by Bank of any Event of Default under this Agreement. 

 9.5 Bank’s Liability for Collateral. Bank has no obligation to clean up or otherwise prepare
the Collateral for sale. All risk of loss, damage or destruction of the Collateral shall be borne by Borrower. 
 9.6 No Obligation to
Pursue Others. Bank has no obligation to attempt to satisfy the Obligations by collecting them from any other person liable for them and Bank may release, modify or waive any collateral provided by any other Person to secure any of the
Obligations, all without affecting Bank’s rights against Borrower. Borrower waives any right it may have to require Bank to pursue any other Person for any of the Obligations. 
 9.7 Remedies Cumulative. Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Bank of one right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on
Borrower’s part shall be deemed a continuing waiver. No delay by Bank shall constitute a waiver, election, or acquiescence by it. No waiver by Bank shall be effective unless made in a written document signed on behalf of Bank and then shall be
effective only in the specific instance and for the specific purpose for which it was given. Borrower expressly agrees that this Section 9.7 may not be waived or modified by Bank by course of performance, conduct, estoppel or otherwise.

 9.8 Demand; Protest. Except as otherwise provided in this Agreement, Borrower waives demand, protest, notice of protest, notice of
default or dishonor, notice of payment and nonpayment and any other notices relating to the Obligations.

	 	11.	CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER. 

 11.1
This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of California, without regard to principles of conflicts of law. Each party hereto hereby submits to the exclusive jurisdiction of the state and
Federal courts located in the County of Santa Clara, State of California. 
 11.2 JURY TRIAL WAIVER. THE UNDERSIGNED ACKNOWLEDGE THAT
THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED UNDER CERTAIN CIRCUMSTANCES. TO THE EXTENT PERMITTED BY LAW, EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS CHOICE, KNOWINGLY
AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY RELATED LOAN DOCUMENT OR ANY OTHER DOCUMENT, INSTRUMENT OR AGREEMENT BETWEEN
THE UNDERSIGNED PARTIES. 
 11.3 JUDICIAL REFERENCE PROVISION. 
 (a) In the event the Jury Trial Waiver set forth in Section 11.2 is not enforceable, the parties elect to proceed under this Judicial Reference
Provision. 
 (b) With the exception of the items specified in clause (c), below, any controversy, dispute or claim (each, a
“Claim”) between the parties arising out of or relating to this Agreement or other Loan Document or any other document, instrument or agreement between the undersigned parties (collectively in this Section, the “Comerica
Documents”), will be resolved by a reference proceeding in California in accordance with the provisions of Sections 638 et seq. of the California Code of Civil Procedure (“CCP”), or their successor sections, which shall constitute the
exclusive remedy for the resolution of any Claim, including whether the Claim is subject to the reference proceeding. Except as otherwise provided in the Comerica Documents, venue for the reference proceeding will be in the state or federal court in
the county or district where the real property involved in the action, if any, is located or in the state or federal court in the county or district where venue is otherwise appropriate under applicable law (the “Court”). 
 (c) The matters that shall not be subject to a reference are the following: (i) nonjudicial foreclosure of any security interests in real or
personal property, (ii) exercise of self-help remedies (including, without limitation, set-off), (iii) appointment of a receiver and (iv) temporary, provisional or ancillary remedies (including, without limitation, writs of
attachment, writs of possession, temporary restraining orders or preliminary injunctions). This reference provision does not limit the right of any party to exercise or oppose any of the rights and remedies described in clauses (i) and
(ii) or to seek or oppose from a court of competent jurisdiction any of the items described in clauses (iii) and (iv). The exercise of, or opposition to, any of those items does not waive the right of any party to a reference pursuant to
this reference provision as provided herein. 
 (d) The referee shall be a retired judge or justice selected by mutual written agreement of
the parties. If the parties do not agree within ten (10) days of a written request to do so by any party, then, upon request of any party, the referee shall be selected by the Presiding Judge of the Court (or his or her representative). A
request for appointment of a referee may be heard on an ex parte or expedited basis, and the parties agree that irreparable harm would result if ex parte relief is not granted. Pursuant to CCP § 170.6, each party shall have one peremptory
challenge to the referee selected by the Presiding Judge of the Court (or his or her representative). 
 (e) The parties agree that time is
of the essence in conducting the reference proceedings. Accordingly, the referee shall be requested, subject to change in the time periods specified herein for good cause shown, to (i) set the matter for a status and trial-setting conference
within fifteen (15) days after the date of selection of the referee, (ii) if practicable, try all issues of law or fact within one hundred twenty (120) days after the date of the conference and (iii) report a statement of
decision within twenty (20) days after the matter has been submitted for decision. 

 (f) The referee will have power to expand or limit the amount and duration of discovery. The referee may
set or extend discovery deadlines or cutoffs for good cause, including a party’s failure to provide requested discovery for any reason whatsoever. Unless otherwise ordered based upon good cause shown, no party shall be entitled to
“priority” in conducting discovery, depositions may be taken by either party upon seven (7) days written notice, and all other discovery shall be responded to within fifteen (15) days after service. All disputes relating to
discovery which cannot be resolved by the parties shall be submitted to the referee whose decision shall be final and binding. 
 (g) Except
as expressly set forth herein, the referee shall determine the manner in which the reference proceeding is conducted including the time and place of hearings, the order of presentation of evidence, and all other questions that arise with respect to
the course of the reference proceeding. All proceedings and hearings conducted before the referee, except for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing
conducted before the referee, and the referee will be provided a courtesy copy of the transcript. The party making such a request shall have the obligation to arrange for and pay the court reporter. Subject to the referee’s power to award costs
to the prevailing party, the parties will equally share the cost of the referee and the court reporter at trial. 
 (h) The referee shall be
required to determine all issues in accordance with existing case law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of California will be applicable to the reference
proceeding. The referee shall be empowered to enter equitable as well as legal relief, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a court proceeding, including without limitation
motions for summary judgment or summary adjudication. The referee shall issue a decision at the close of the reference proceeding which disposes of all claims of the parties that are the subject of the reference. Pursuant to CCP § 644, such
decision shall be entered by the Court as a judgment or an order in the same manner as if the action had been tried by the Court and any such decision will be final, binding and conclusive. The parties reserve the right to appeal from the final
judgment or order or from any appealable decision or order entered by the referee. The parties reserve the right to findings of fact, conclusions of laws, a written statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted, is also to be a reference proceeding under this provision. 
 (i) If the enabling legislation which
provides for appointment of a referee is repealed (and no successor statute is enacted), any dispute between the parties that would otherwise be determined by reference procedure will be resolved and determined by arbitration. The arbitration will
be conducted by a retired judge or justice, in accordance with the California Arbitration Act §1280 through §1294.2 of the CCP as amended from time to time. The limitations with respect to discovery set forth above shall apply to any such
arbitration proceeding. 
 (j) THE PARTIES RECOGNIZE AND AGREE THAT ALL CONTROVERSIES, DISPUTES AND CLAIMS RESOLVED UNDER THIS REFERENCE
PROVISION WILL BE DECIDED BY A REFEREE AND NOT BY A JURY. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS, HIS OR HER OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, AGREES
THAT THIS REFERENCE PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN OR AMONG THEM ARISING OUT OF OR IN ANY WAY RELATED TO, THIS AGREEMENT OR OTHER LOAN DOCUMENTS OR THE OTHER COMERICA DOCUMENTS. 
  

	 	12.	GENERAL PROVISIONS. 

 12.1 Successors and
Assigns. This Agreement shall bind and inure to the benefit of the respective successors and permitted assigns of each of the parties and shall bind all persons who become bound as a debtor to this Agreement; provided, however, that neither this
Agreement nor any rights hereunder may be assigned by Borrower or any Guarantor without Bank’s prior written consent, which consent may be granted or withheld in Bank’s sole discretion. Bank shall have the right without the consent of or
notice to Borrower or any Guarantor to sell, transfer, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights and benefits hereunder. 

 12.2 Indemnification. Borrower and each Guarantor shall defend, indemnify and hold harmless Bank
and its officers, employees, and agents against: (a) all obligations, demands, claims, and liabilities claimed or asserted by any other party in connection with the transactions contemplated by this Agreement except for obligations, demands,
claims, and liabilities caused by Bank’s gross negligence or willful misconduct as finally determined by a court of competent jurisdiction; and (b) all losses or Bank Expenses in any way suffered, incurred, or paid by Bank, its officers,
employees and agents as a result of or in any way arising out of, following, or consequential to transactions between Bank, Borrower and Guarantors whether under this Agreement, or otherwise (including without limitation reasonable attorneys fees
and expenses), except for losses or Bank Expenses caused by Bank’s gross negligence or willful misconduct as finally determined by a court of competent jurisdiction. 
 12.3 Time of Essence. Time is of the essence for the performance of all obligations set forth in this Agreement. 
 12.4 Severability of Provisions. Each provision of this Agreement shall be severable from every other provision of this Agreement for the purpose of determining the legal enforceability of any specific
provision. 
 12.5 Amendments in Writing, Integration. All amendments to or terminations of this Agreement or the other Loan Documents
must be in writing. All prior agreements, understandings, representations, warranties, and negotiations between the parties hereto with respect to the subject matter of this Agreement and the other Loan Documents, if any, are merged into this
Agreement and the Loan Documents. 
 12.6 Counterparts. This Agreement may be executed in any number of counterparts and by different
parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement. 
 12.7 Survival. All covenants, representations and warranties made in this Agreement shall continue in full force and effect so long as any
Obligations remain outstanding or Bank has any obligation to make any Credit Extension to Borrower. The obligations of Borrower and Guarantors to indemnify Bank with respect to the expenses, damages, losses, costs and liabilities described in this
Agreement shall survive until all applicable statute of limitations periods with respect to actions that may be brought against Bank have run. 
 12.8 Confidentiality. In handling any confidential information, Bank and all employees and agents of Bank shall exercise the same degree of care that Bank exercises with respect to its own proprietary information of the same types to
maintain the confidentiality of any non-public information thereby received or received pursuant to this Agreement except that disclosure of such information may be made (i) to the subsidiaries or Affiliates of Bank in connection with their
present or prospective business relations with Borrower or any Guarantor, (ii) to prospective transferees or purchasers of any interest in the Loans, provided that they have entered into a comparable confidentiality agreement in favor of
Borrower and Guarantors and have delivered a copy to Borrower and Guarantors, (iii) as required by law, regulations, rule or order, subpoena, judicial order or similar order, (iv) as may be required in connection with the examination,
audit or similar investigation of Bank and (v) as Bank may determine in connection with the enforcement of any remedies hereunder. Confidential information hereunder shall not include information that either: (a) is in the public domain or
in the knowledge or possession of Bank when disclosed to Bank, or becomes part of the public domain after disclosure to Bank through no fault of Bank; or (b) is disclosed to Bank by a third party, provided Bank does not have actual knowledge
that such third party is prohibited from disclosing such information. 

 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed as of the date first
above written.

 7. Selection/Conversion of Interest Rate
Options for U.S. Dollar Advances. At the time any U.S. Dollar Advance is requested under the Loan Agreement and/or Borrower wishes to select the U.S. LIBOR Rate for all or a portion of the outstanding principal balance of
U.S. Dollar Advances under the Loan Agreement, and at the end of each applicable Interest Period, Borrower shall give Bank a notice specifying (a) the interest rate option selected by Borrower; (b) the principal amount subject
thereto; and (c) if the U.S. LIBOR Rate is selected, the length of the applicable Interest Period. Any such notice may be given by telephone so long as, with respect to each U.S. LIBOR Advance requested by Borrower, (i) Bank receives
written confirmation from Borrower not later than three (3) Business Days after such telephone notice is given; and (ii) such notice is given to Bank prior to 10:00 a.m., California time, on the first day of the Interest Period. For each
U.S. LIBOR Rate requested hereunder, Bank will quote the fixed Applicable Interest Rate to Borrower at approximately 10:00 a.m., California time, on the first day of the Interest Period. If Borrower does not immediately accept the rate quoted by
Bank, any subsequent acceptance by Borrower shall be subject to a redetermination of the rate by Bank; provided, however, that if Borrower fails to accept any such quotation given, then the quoted rate shall expire and Bank shall have no obligation
to permit a U.S. LIBOR Advance to be selected on such day. If no specific designation of interest is made at the time any U.S. Dollar Advance is requested under the Loan Agreement or at the end of any Interest Period, Borrower shall be deemed
to have selected the U.S. Base Rate for such U.S. Dollar Advance or the principal amount to which such Interest Period applied. At any time the U.S. LIBOR Rate is in effect, Borrower may, at the end of the applicable Interest Period, convert to
the U.S. Base Rate. At any time the U.S. Base Rate is in effect, Borrower may convert to the U.S. LIBOR Rate, and shall designate an Interest Period.

 8. Selection of Interest Rate Options for Alternative Currency Advances. At the time any Alternative Currency
Advance is requested under the Loan Agreement, and at the end of each applicable Interest Period, Borrower shall give Bank a notice specifying (a) the interest rate option selected by Borrower, if such an option is available; (b) the
principal amount and type of Alternative Currency subject thereto; and (c) the length of the applicable Interest Period. Any such notice may be given by telephone so long as, with respect to each Alternative Currency Advance requested by
Borrower, (i) Bank receives written confirmation from Borrower not later than three (3) Business Days after such telephone notice is given; and (ii) such notice is given to Bank prior to 10:00 a.m., Eastern Time, two Business Days
prior to the first day of the Interest Period. For each Alternative Currency Advance requested by Borrower, Bank will quote the fixed Applicable Interest Rate to Borrower at approximately 10:00 a.m., Easter Time, two Business Days prior to the first
day of the Interest Period. If Borrower does not immediately accept the rate quoted by Bank, any subsequent acceptance by Borrower shall be subject to a redetermination of the rate by Bank; provided, however, that if Borrower fails to accept any
such quotation given, then the quoted rate shall expire and Bank shall have no obligation to permit such Alternative Currency Advance to be made within the next two Business Days. If no specific designation of interest is made at the end of any
Interest Period applicable to an Alternative Currency Advance, Borrower shall be deemed to have requested a U.S. Dollar Advance in the amount of the U.S. Dollar Equivalent of the principal amount of such Alternate Currency Advance plus any
accrued and unpaid interest due thereof, which U.S. Dollar Advance shall bear interest at the U.S. Base Rate plus three percent. 
 9.
Prepayment. If (i) any payment or prepayment of any outstanding principal balance of any Advance to which an Interest Period is applicable, shall occur on any day other than the last day of such Interest Period (whether voluntarily, by
acceleration, required payment, or otherwise), (ii) Borrower elects the U.S. LIBOR Advance or an Alternative Currency Advance in accordance with the terms and conditions hereof, and, subsequent to such election, but prior to the commencement of
the applicable Interest Period, Borrower revokes such election for any reason whatsoever, (iii) the applicable interest rate in respect of any outstanding U.S. Dollar Advances shall be changed, for any reason whatsoever, from the U.S.
LIBOR Rate to the U.S. Base Rate prior to the last day of the applicable Interest Period, or (iv) if Borrower shall fail to make any payment of principal or interest hereunder at any time with respect to any Advance, other than as U.S. Base
Rate Advance to which an Interest Period is applicable, Borrower shall reimburse Bank, on demand, for any resulting loss, cost or expense incurred by Bank as a result thereof, including, without limitation, any such loss, cost or expense incurred in
obtaining, liquidating, employing or redeploying deposits from third parties. Such amount payable by Borrower to Bank may include, without limitation, an amount equal to the excess, if any, of (a) the amount of interest which would have accrued
on the amount so prepaid, or not so borrowed, refunded or converted, for the period from the date of such prepayment or of such failure to borrow, refund or convert, through the last day of the relevant Interest Period, at the Applicable Interest
Rate for such outstanding principal balance under the Loan Agreement, as provided in this Addendum, over (b) the amount of interest (as reasonably determined by Bank) which would have accrued to Bank on such amount by placing such amount on
deposit for a comparable period with leading banks in the applicable interbank market. Calculation of any amounts payable to Bank under this paragraph shall be made as though Bank shall have actually funded or committed to fund the relevant
outstanding principal balance of the Loan Agreement hereunder through the purchase of an underlying deposit in an amount equal to the amount of such outstanding principal balance of the Loan Agreement and having a maturity comparable to the relevant
Interest Period; provided, however, that Bank may fund the outstanding principal balance of the Loan Agreement hereunder in any manner it deems fit and the foregoing assumptions shall be utilized only for the purpose of the calculation of amounts
payable under this paragraph. Upon the written request of Borrower, Bank shall deliver to Borrower a certificate setting forth the basis for determining such losses, costs and expenses, which certificate shall be conclusively presumed correct,
absent manifest error. Any prepayment hereunder shall also be accompanied by the payment of all accrued and unpaid interest on the amount so prepaid. The outstanding principal balance of any U.S. Base Rate Advance under the Loan Agreement may be
prepaid without penalty or premium. Partial prepayments hereunder shall be applied to the installments hereunder in the inverse order of their maturities.

 BY INITIALING BELOW, BORROWER ACKNOWLEDGE(S) AND AGREE(S) THAT: (A) THERE IS NO RIGHT TO PREPAY ANY ADVANCE, OTHER
THAN U.S. BASE RATE ADVANCES, IN WHOLE OR IN PART, WITHOUT PAYING THE PREPAYMENT AMOUNT SET FORTH HEREIN (“PREPAYMENT AMOUNT”), EXCEPT AS OTHERWISE REQUIRED UNDER APPLICABLE LAW; (B) BORROWER SHALL BE LIABLE FOR PAYMENT OF THE
PREPAYMENT AMOUNT IF BANK EXERCISES ITS RIGHT TO ACCELERATE PAYMENT OF ANY SUCH ADVANCE AS PART OR ALL OF THE OBLIGATIONS OWING UNDER THE LOAN AGREEMENT, INCLUDING WITHOUT LIMITATION, ACCELERATION UNDER A DUE-ON-SALE PROVISION; (C) BORROWER
WAIVES ANY RIGHTS UNDER SECTION 2954.10 OF THE CALIFORNIA CIVIL CODE OR ANY SUCCESSOR STATUTE; AND (D) BANK HAS MADE EACH SUCH ADVANCE PURSUANT TO THE LOAN AGREEMENT IN RELIANCE ON THESE AGREEMENTS. 
  

			
	  
	 	
	BORROWER’S INITIALS	 	

 10. Hold Harmless and Indemnification. Borrower agrees to indemnify Bank and to hold Bank harmless from,
and to reimburse Bank on demand for, all losses and expenses which Bank sustains or incurs as a result of (i) any payment of any Advance to which an Interest Period is applicable, prior to the last day of such Interest Period for any reason,
including, without limitation, termination of the Loan Agreement, whether pursuant to this Addendum or the occurrence of an Event of Default; (ii) any termination of an Interest Period prior to the date it would otherwise end in accordance with
this Addendum; or (iii) any failure by Borrower, for any reason, to borrow any portion of any requested Advance, other than a U.S. Base Rate Advance. 
 11. Funding Losses. The indemnification and hold harmless provisions set forth in this Addendum shall include, without limitation, all losses and expenses arising from interest and fees that Bank pays to lenders of funds it obtains
in order to fund the loans to Borrower on the basis of any Advance(s) (other than U.S. Base Rate Advances) and all losses incurred in liquidating or re-deploying deposits from which such funds were obtained and loss of profit for the period after
termination. A written statement by Bank to Borrower of such losses and expenses shall be conclusive and binding, absent manifest error, for all purposes. This obligation shall survive the termination of this Addendum and the payment of the Loan
Agreement. 
 12. Regulatory Developments Or Other Circumstances Relating To Illegality or Impracticality of Advances. If any Regulatory Development
or other circumstances relating to the interbank Euro-dollar markets, or any other applicable interbank markets, shall, at any time, in Bank’s reasonable determination, make it unlawful or impractical for Bank to fund or maintain, during any
Interest Period, to determine or charge interest rates based upon LIBOR, TIBOR or SIBOR, Bank shall give notice of such circumstances to Borrower and: 
  

	 	(i)	In the case of an Interest Period in progress, Borrower shall, if requested by Bank, promptly pay any interest which had accrued prior to such request and the date of such request
shall be deemed to be the last day of the term of such Interest Period; and 

  

	 	(ii)	No such Interest Period may be designated thereafter until Bank determines that such would be practical. 

 13. Additional Costs. Borrower shall pay to Bank from time to time, upon Bank’s request, such amounts as Bank determines are needed to compensate Bank for any costs it incurred which are attributable to
Bank having made or maintained a U.S. LIBOR Advance or Alternative Currency Advance or to Bank’s obligation to make such Advances, or any reduction in any amount receivable by Bank hereunder with respect to any such Advance or Applicable
Interest Rate or such obligation (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), resulting from any Regulatory Developments, which (i) change the basis of taxation of any amounts
payable to Bank hereunder with respect to taxation of any amounts payable to Bank hereunder with respect to any 

  

 7 

 
such Advance (other than taxes imposed on the overall net income of Bank for any such Advance by the jurisdiction where Bank is headquartered or the
jurisdiction where Bank extends such Advance); (ii) impose or modify any reserve, special deposit, or similar requirements relating to any extensions of credit or other assets of, or any deposits with or other liabilities of, Bank (including
any such Advance or any deposits referred to in the definitions of LIBOR, SIBOR and TIBOR); or (iii) impose any other condition affecting this Addendum (or any of such extension of credit or liabilities). Bank shall notify Borrower of any event
occurring after the date hereof which entitles Bank to compensation pursuant to this paragraph as promptly as practicable after it obtains knowledge thereof and determines to request such compensation. Determinations by Bank for purposes of this
paragraph, shall be conclusive, provided that such determinations are made on a reasonable basis. 
 14. Legal Effect. Except as specifically modified
hereby, all of the terms and conditions of the Loan Agreement remain in full force and effect.
