1997 Amended Long-Term Incentive and Stock Option Plan and related documents

 Exhibit 10.3 
 AMENDED AND RESTATED 
 1997 LONG-TERM INCENTIVE 

 AND 
 STOCK OPTION PLAN 
 1. Purpose of Plan. 
 The “Optical Solutions, Inc. 1997 LONG-TERM INCENTIVE AND STOCK OPTION PLAN” is hereby amended and restated as set forth herein
and, as so amended and restated, is hereinafter referred to as the “Plan”. The purpose of the Plan is to aid in maintaining and developing personnel capable of assuring the future success of Optical Solutions, Inc., a Delaware corporation
(the “Company”), to offer such personnel additional incentives to put forth maximum efforts for the success of the business, and to afford them an opportunity to acquire a proprietary interest in the Company through stock options and other
long-term incentive awards as provided herein. Options granted under this Plan may be either incentive stock options (“Incentive Stock Options”) within the meaning of Section 422 of the Internal Revenue Code of 1986 (the
“Code”), or options which do not qualify as Incentive Stock Options. Awards granted under this Plan shall be stock appreciation rights (“SARs”), restricted stock or performance awards as hereinafter described. Optical Solutions,
Inc., a Minnesota corporation, (“Optical Solutions—Minnesota”) was originally the sponsor of the Plan. Pursuant to that certain Agreement and Plan of Merger dated as of March __, 1999, Optical Solutions—Minnesota was merged with
and into the Company (the “Merger”) and, effective as of the consummation of the Merger, the Plan and all outstanding awards thereunder were assumed by the Company. 
 2. Stock Subject to Plan. 
 Subject to the provisions of
Section 14 hereof, the stock to be subject to options or other awards under the Plan shall be the Company’s authorized Common Stock, par value $.01 per share (the “Common Shares”). Such shares may be either authorized but
unissued shares, or issued shares which have been reacquired by the Company. Subject to adjustment as provided in Section 14 hereof, the maximum number of shares on which options may be exercised or other award issued under this Plan shall be
4,500,000 shares. If an option or award under the Plan expires, or for any reason is terminated or unexercised with respect to any shares, such shares shall again be available for options or awards thereafter granted during the term of the Plan. The
stock to be subject to options or other awards outstanding under the Plan from and after the consummation of the Merger shall be Common Shares of the Company. From and after the consummation of the Merger, no option or other award previously granted
hereunder shall be exercisable or have outstanding rights with respect to the common stock of Optical Solutions—Minnesota. 
 3.
Administration of Plan. 
 (a) Except as provided in Section 3(b) or Section 3(e) hereof, the Plan shall be
administered by the Board of Directors of the Company or a committee thereof. The members of any such committee shall be appointed by and serve at the pleasure of the Board of Directors. If no committee is appointed by the Board, the committee shall
be comprised of all of the members of the Board of Directors. (The group administering the Plan shall hereinafter be referred to as the “Committee”.) 

 (b) Notwithstanding Section 3(a) hereof, all option grants and awards under this Plan
to officers, directors and others who are subject to Section 16 under the Securities Exchange Act of 1934, as amended, and the rules of the Securities and Exchange Commission promulgated thereunder, shall be made exclusively by a committee (the
“Disinterested Committee”). The Disinterested Committee may be a subcommittee of the Committee and shall be comprised of at least two members of the Board of Directors who have not received any option or award under the Plan during the
preceding 12 months. Such persons shall not be eligible for option grants or awards while serving on the Disinterested Committee. All references hereinafter to the “Committee” shall mean the “Disinterested Committee” if the
action to be taken in administration of the Plan must be taken by the Disinterested Committee. 
 (c) The Committee shall have
plenary authority in its discretion, but subject to the express provisions of the Plan: (i) to determine the purchase price of the Common Stock covered by each option or award, (ii) to determine the employees to whom and the time or times
at which such options and awards shall be granted and the number of shares to be subject to each, (iii) to determine the form of payment to be made upon the exercise of an SAR or in connection with performance awards, either cash, Common Shares
of the Company or a combination thereof, (iv) to determine the terms of exercise of each option and award, (v) to accelerate the time at which all or any part of an option or award may be exercised, (vi) to amend or modify the terms
of any option or award with the consent of the optionee, (vii) to interpret the Plan, (viii) to prescribe, amend and rescind rules and regulations relating to the Plan, (ix) to determine the terms and provisions of each option and
award agreement under the Plan (which agreements need not be identical), including the designation of those options intended to be Incentive Stock Options, and (x) to make all other determinations necessary or advisable for the administration
of the Plan, subject to the exclusive authority of the Board of Directors under Section 15 herein to amend or terminate the Plan. The Committee’s determinations on the foregoing matters, unless otherwise disapproved by the Board of
Directors of the Company, shall be final and conclusive. 
 (d) The Committee may select one of its members as its Chairman and
shall holds its meetings at such times and places as it may determine. A majority of its members shall constitute a quorum. All determinations of the Committee shall be made by not less than a majority of its members. Any decision or determination
reduced to writing and signed by all of the members of the Committee shall be fully effective as if it had been made by a majority vote at a meeting duly called and held. The grant of an option or award shall be effective only if a written agreement
shall have been duly executed and delivered by and on behalf of the Company following such grant. The Committee may appoint a Secretary and may make such rules and regulations for the conduct of its business as it shall deem advisable. 

4. Eligibility. 
 Incentive Stock Options may only be granted under this Plan to any full or part-time employee (which term as used herein includes, but is not limited to, officers and directors who are also employees) of the Company and of its present and
future subsidiary corporations (herein called “subsidiaries”). Full or part-time employees, non-employee members of the Board of

  

 2 

 
Directors, and non-employee consultants, agents or independent contractors to the Company or one of its subsidiaries shall be eligible to receive options which do not qualify as Incentive Stock
Options and awards. Members of the Disinterested Committee shall not be eligible for any option grant or award under the Plan while serving on said Disinterested Committee. In determining the persons to whom options and awards shall be granted and
the number of shares subject to each, the Committee may take into account the nature of services rendered by the respective employees or consultants, their present and potential contributions to the success of the Company and such other factors as
the Committee in its discretion shall deem relevant. A person who has been granted an option or award under this Plan may be granted additional options or awards under the Plan if the Committee shall so determine; provided, however, that for
Incentive Stock Options, to the extent the aggregate fair market value (determined at the time the Incentive Stock Option is granted) of the Common Shares with respect to which all Incentive Stock Options are exercisable for the first time by an
employee during any calendar year (under all plans described in subsection (d) of Section 422 of the Code of his employer corporation and its parent and subsidiary corporations) exceeds $100,000, such options shall be treated as options
which do not qualify as Incentive Stock Options. Nothing in the Plan or in any agreement thereunder shall confer on any employee any right to continue in the employ of the Company or any of its subsidiaries or affect, in any way, the right of the
Company or any of its subsidiaries to terminate his or her employment at the time. 
 5. Price. 
 The option price for all Incentive Stock Options granted under the Plan shall be determined by the Committee but shall not be less than 100%
of the fair market value of the Common Shares at the date of grant of such option. The option price for options granted under the Plan which do not qualify as Incentive Stock Options and, if applicable, the price for all awards shall also be
determined by the Committee and may be other than 100% of the fair market value of the Common Shares. For purposes of the preceding sentence and for all other valuation purposes under the Plan, the fair market value of the Common Shares shall be as
reasonably determined by the Committee. If on the date of grant of any option or award hereunder the Common Shares are not traded on an established securities market, the Committee shall make a good faith attempt to satisfy the requirements of this
Section 5 and in connection therewith shall take such action as it deems necessary or advisable. The option price for all Incentive Stock Options and options which do not qualify as Incentive Stock Options granted under the Plan and outstanding
under the Plan immediately prior to the Merger, whether or not vested, shall be the same price as set forth in the option agreement immediately prior to the Merger. Notwithstanding the preceding sentence, the option price for each such Incentive
Stock Option shall in no event be less than the price which bears the same ratio to the option price immediately prior to the Merger as the fair market value of a Common Share immediately after the Merger bears to the fair market value of a share of
common stock of Optical Solutions—Minnesota immediately prior to the Merger. Subject to the foregoing, the number of shares subject to Incentive Stock Options shall be adjusted so that the aggregate option price for all such Incentive Stock
Options is the same immediately after the Merger as it was immediately prior to the Merger. 
  

 3 

 6. Term. 
 Each option and award and all rights and obligations thereunder shall expire on the date determined by the Committee and specified in the option or award agreement. The Committee shall be under no duty to
provide terms of like duration for options or awards granted under the Plan, but the term of an Incentive Stock Option may not extend more than ten (10) years from the date of grant of such option and the term of options granted under the Plan
which do not qualify as Incentive Stock Options may not extend more than fifteen (15) years from the date of granting of such option. 
 7. Exercise of Option or Award. 
 (a) The Committee shall have full and complete authority to determine
whether an option or award will be exercisable in full at any time or from time to time during the term thereof, or to provide for the exercise thereof in such installments, upon the occurrence of such events (such as termination of employment for
any reason) and at such times during the term of the option as the Committee may determine and specify in the option or award agreement. 
 (b) The exercise of any option or award granted hereunder shall only be effective at such time that the sale of Common Shares pursuant to such exercise will not violate any state or federal securities or
other laws. 
 (c) An optionee or grantee electing to exercise an option or award shall give written notice to the Company of
such election and of the number of shares subject to such exercise, The full purchase price of such shares shall be tendered with such notice of exercise. Payment shall be made to the Company in cash (including bank check, certified check, personal
check, or money order), or, at the discretion of the Committee and as specified by the Committee, (i) by delivering certificates for the Company’s Common Shares already owned by the optionee or grantee having a fair market value as of the
date of grant equal to the full purchase price of the shares, (ii) by delivering a combination of cash and such shares, or (iii) by delivering (including by fax) to the Company or its designated agent an executed irrevocable option
exercise form together with irrevocable instructions to a broker-dealer to sell or margin the Common Shares and deliver the sale or margin loan proceeds directly to the Company to the extent required to pay the option exercise price. 
 (d) The fair market value of the Common Shares which are tendered in payment of the exercise price shall be determined as provided in
Section 5 herein. 
 (e) Until such person has been issued the shares subject to such exercise, he or she shall possess no
rights as a shareholder with respect to such shares. 
 8. Additional Restrictions. 
 The Committee shall have full and complete authority to determine whether all or any part of the Common Shares of the Company acquired upon
exercise of any of the options or awards granted under the Plan shall be subject to restrictions on the transferability thereof or any other restrictions affecting in any manner the optionee’s or grantee’s rights with respect thereto, but
any such restriction shall be contained in the agreement relating to such options or awards. 
  

 4 

 9. Alternative Stock Appreciation Rights. 
 (a) Grant. At the time of grant of an option or award under the Plan (or at any other time), the Committee, in its discretion, may
grant a Stock Appreciation Right (“SAR”) evidenced by an agreement in such form as the Committee shall from time to time approve. Any such SAR may be subject to restrictions on the exercise thereof as may be set forth in the agreement
representing such SAR which agreement shall comply with and be subject to the following terms and conditions and any additional terms and conditions established by the Committee that are consistent with the terms of the Plan. 
 (b) Exercise. A SAR shall be exercised by the delivery to the Company of a written notice which shall state that the holder thereof
elects to exercise his or her SAR as to the number of shares specified in the notice and which shall further state what portion, if any, of the SAR exercise amount (hereinafter defined) the holder thereof requests be paid to in cash and what
portion, if any, is to be paid in Common Shares of the Company. The Committee promptly shall cause to be paid to such holder the SAR exercise amount either in cash, in Common Shares of the Company, or any combination of cash and shares as the
Committee may determine. Such determination may be either in accordance with the request made by the holder of the SAR or in the sole and absolute discretion of the Committee. The SAR exercise amount is the excess of the fair market value of one
share of the Company’s Common Shares on the date of exercise over the per share exercise price in respect of which the SAR was granted, multiplied by the number of shares as to which the SAR is exercised. For the purposes hereof, the fair
market value of the Company’s shares shall be determined as provided in Section 5 herein. 
 10. Ten Percent Shareholder
Rule. 
 Notwithstanding any other provision in the Plan, if at the time an option is granted pursuant to the Plan the
optionee owns directly or indirectly (within the meaning of Section 425(d) of the Code) Common Shares of the Company possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or its
parent or subsidiary corporations, if any (within the meaning of Section 422(b)(6) of the Code), then any Incentive Stock Option to be granted to such optionee pursuant to the Plan shall satisfy the requirements of Section 422(c)(6) of the
Code, and the option price shall be not less than 110% of the fair market value of the Common Shares of the Company determined as described herein, and such option by its terms shall not be exercisable after the expiration of five (5) years
from the date such option is granted. 
 11. Non-Transferability. 
 No option or award granted under the Plan shall be transferable by an optionee or grantee, otherwise than by will or the laws of descent or
distribution. Except as otherwise provided in an option or award agreement, during the lifetime of an optionee or grantee, the option shall be exercisable only by such optionee or grantee. 
 12. Restricted Stock Awards. 
 Awards of Common Shares subject to forfeiture and transfer restrictions may be granted by the Committee. Any restricted stock award shall be evidenced by an agreement in such form

  

 5 

 
as the Committee shall from time to time approve, which agreement shall comply with and be subject to the following terms and conditions and any additional terms and conditions established by the
Committee that are consistent with the terms of the Plan: 
 (a) Grant of Restricted Stock Awards. Each restricted stock
award made under the Plan shall be for such number of Common Shares as shall be determined by the Committee and set forth in the agreement containing the terms of such restricted stock award. Such agreement shall set forth a period of time during
which the grantee must remain in the continuous employment of the Company in order for the forfeiture and transfer restrictions to lapse. If the Committee so determines, the restrictions may lapse during such restricted period in installments with
respect to specified portions of the shares covered by the restricted stock award. The agreement may also, in the discretion of the Committee, set forth performance or other conditions that will subject the Common Shares to forfeiture and transfer
restrictions. The Committee may, at its discretion, waive all or any part of the restrictions applicable to any or all outstanding restricted stock awards. 
 (b) Delivery of Common Shares and Restrictions. At the time of a restricted stock award, a certificate representing the number of Common Shares awarded thereunder shall be registered in the name of
the grantee. Such certificate shall be held by the Company or any custodian appointed by the Company for the account of the grantee subject to the terms and conditions of the Plan, and shall bear such a legend setting forth the restrictions imposed
thereon as the Committee, in its discretion, may determine. The grantee shall have all rights of a shareholder with respect to the Common Shares, including the right to receive dividends and the right to vote such shares, subject to the following
restrictions: (i) the grantee shall not be entitled to delivery of the stock certificate until the expiration of the restricted period and the fulfillment of any other restrictive conditions set forth in the restricted stock agreement with
respect to such Common Shares; (ii) none of the Common Shares may be sold, assigned, transferred, pledged, hypothecated or otherwise encumbered or disposed of during such restricted period or until after the fulfillment of any such other
restrictive conditions; and (iii) except as otherwise determined by the Committee, all of the Common Shares shall be forfeited and all rights of the grantee to such Common Shares shall terminate, without further obligation on the part of the
Company, unless the grantee remains in the continuous employment of the Company for the entire restricted period in relation to which such Common Shares were granted and unless any other restrictive conditions relating to the restricted stock award
are met. Any Common Shares, any other securities of the Company and any other property (except for cash dividends) distributed with respect to the Common Shares subject to restricted stock awards shall be subject to the same restrictions, terms and
conditions as such restricted Common Shares. 
 (c) Termination of Restrictions. At the end of the restricted period and
provided that any other restrictive conditions of the restricted stock award are met, or at such earlier time as otherwise determined by the Committee, all restrictions set forth in the agreement relating to the restricted stock award or in the Plan
shall lapse as to the restricted Common Shares subject thereto, and a stock certificate for the appropriate number of Common Shares, free of the restrictions and the restricted stock legend, shall be delivered to the grantee or his beneficiary or
estate, as the case may be. 
  

 6 

 13. Performance Awards. 
 The Committee is further authorized to grant Performance awards. Subject to the terms of this Plan and any applicable award agreement, a
Performance award granted under the Plan (i) may be denominated or payable in cash, Common Shares (including, without limitation, restricted stock), other securities, other awards, or other property and (ii) shall confer on the holder
thereof rights valued as determined by the Committee, in its discretion, and payable to, or exercisable by, the holder of the Performance awards, in whole or in part, upon the achievement of such performance goals during such performance periods as
the Committee, in its discretion, shall establish. Subject to the terms of this Plan and any applicable award agreement, the performance goals to be achieved during any performance period, the length of any performance period, the amount of any
Performance award granted, and the amount of any payment or transfer to be made by the granter and by the Company under any Performance award shall be determined by the Committee. 
 14. Dilution or Other Adjustments. 
 If there shall be any change in
the Common Shares through merger, consolidation, reorganization, recapitalization, dividend in the form of stock (of whatever amount), stock split or other change in the corporate structure, appropriate adjustments in the Plan and outstanding
options and awards shall be made by the Committee. In the event of any such changes, adjustments shall include, where appropriate, changes in the aggregate number of shares subject to the Plan, the number of shares and the price per share subject to
outstanding options and awards and the amount payable upon exercise of outstanding awards, in order to prevent dilution or enlargement of option or award rights. 
 15. Amendment or Discontinuance of Plan. 
 The Board of Directors may
amend or discontinue the Plan at any time. Subject to the provisions of Section 14 no amendment of the Plan, however, shall without shareholder approval: (i) increase the maximum number of shares under the Plan as provided in
Section 2 herein, (ii) decrease the minimum price provided in Section 5 herein, (iii) extend the maximum term under Section 6, or (iv) modify the eligibility requirements for participation in the Plan. The Board of
Directors shall not alter or impair any option or award theretofore granted under the Plan without the consent of the holder of the option or award. 
 16. Time of Granting. 
 Nothing contained in the Plan or in any resolution adopted or to be adopted by
the Board of Directors or by the shareholders of the Company, and no action taken by the Committee or the Board of Directors (other than the execution and delivery of an option or award agreement), shall constitute the granting of an option or award
hereunder. 
 17. Income Tax-Withholding and Tax Bonuses. 
 (a) In order to comply with all applicable federal or state income tax laws or regulations, the Company may take such action as it deems
appropriate to ensure that all applicable federal or state payroll, withholding, income or other taxes, which are the sole and

  

 7 

 
absolute responsibility of an optionee or grantee under the Plan, are withheld or collected from such optionee or grantee. In order to assist an optionee or grantee in paying all federal and
state taxes to be withheld or collected upon exercise of an option or award which does not qualify as an Incentive Stock Option hereunder, the Committee, in its absolute discretion and subject to such additional terms and conditions as it may adopt,
shall permit the optionee or grantee to satisfy such tax obligation by (i) electing to have the Company withhold a portion of the shares otherwise to be delivered upon exercise of such option or award with a fair market value, determined in
accordance with Section 5 herein, equal to such taxes or (ii) delivering to the Company Common Shares other than the shares issuable upon exercise of such option or award with a fair market value, determined in accordance with
Section 5, equal to such taxes. 
 (b) The Committee shall have the authority, at the time of grant of an option under the
Plan or at any time thereafter, to approve tax bonuses to designated optionee or grantees to be paid upon their exercise of options or awards granted hereunder. The amount of any such payment shall be determined by the Committee. The Committee shall
have full authority in its absolute discretion to determine the amount of any such tax bonus and the terms and conditions affecting the vesting and payment thereafter. 
 18. Effective Date and Termination of Plan. 
 (a) The Plan was
initially approved by the Board of Directors on February 21, 1997 and by the shareholders of the Company on February 28, 1997, and the amendment and restatement of the Plan was approved by the Board of Directors on March 22, 1999 and
by the shareholders of the Company on April 7, 1999. 
 (b) Unless the Plan shall have been discontinued as provided in
Section 14 hereof, the Plan shall terminate on February 28, 2007. No option or award may be granted after such termination, but termination of the Plan shall not, without the consent of the optionee or grantee, alter or impair any rights
or obligations under any option or award theretofore granted. 
 Executed this      day of April,
1999.

1997 LONG-TERM INCENTIVE AND STOCK OPTION PLAN 
 Optical Solutions, Inc., a Delaware corporation (the
“Corporation”), by duly adopted resolution of its board of directors pursuant to Section 15 of the Amended and Restated 1997 Long-Term Incentive and Stock Option Plan, as amended (the “Plan”), hereby amends the Plan subject
to approval of the Corporation’s stockholders as follows: 
 I. 
 WHEREAS, the Board of Directors of the Corporation has approved the Corporation to issue and sell to certain private investors and/or
existing stockholders (collectively, “Investors”) an aggregate of up to 14,000,000 shares (the “Series III Shares”) of its Series III Preferred Stock, par value $.001 per share (“Series III Preferred”) in two or more
closings, at a purchase price of $.89 per share (the “Financing”); and 
 WHEREAS, in connection with the Financing,
each Investor who is an holder of, the Corporation’s existing Preferred Stock (which includes the Series A-1 Preferred, Series A-2 Preferred, Series B Preferred, Series C Preferred, Series D Preferred, Series E Preferred, Series F Preferred and
Series G Preferred, collectively, “Existing Preferred”) shall be entitled to exchange (the “Series II Exchange”) (i) shares of its Existing Preferred having an aggregate cost basis equal to five times the purchase price paid
by such Investor for shares of Series III Preferred in the initial closing of the Financing (“Closing”) into (ii) shares of its Series II Preferred Stock, par value $.001 per share (“Series II Preferred”), with a deemed
issuance price of $1.89 per share; and 
 WHEREAS, immediately after the Closing, all of the issued and outstanding shares of
the Corporation’s Existing Preferred that have not been exchanged for Series II Shares pursuant to the Series II Exchange, shall automatically convert into shares of the Corporation’s Series I Preferred Stock, par value $.001 per share
(“Series I Preferred Stock”), in accordance with the Amendment to the Certificate of Incorporation of the Corporation (“Charter Amendment”) in the form approved by the Board of Directors (the “Recapitalization”); and

 WHEREAS, the Charter Amendment, as approved by the Board of Directors of the Corporation: (i) effectuates the
Recapitalization; (ii) effectuates a one for one-one hundredth (.01) share reverse stock split (“Reverse Stock Split”) of the Corporation’s common stock, par value $.01 per share (“Common Stock”); and (iii) adjusts
the par value of the Corporation’s authorized Common Stock and Preferred Stock, in each case, to $.001 par value per share (collectively the “Related Transaction”); and 
 WHEREAS, currently, the maximum number of shares on which options may be exercised or other awards issued under the Plan is
“68,272,380” shares of Common Stock; and 
 WHEREAS, upon the filing of the Charter Amendment with the Secretary of
State of the State of Delaware, under Section 14 of the Plan, the maximum number of shares on which options may be exercised or other awards issued under the Plan shall be adjusted to “682,723” to reflect the Reverse Stock Split; and

 WHEREAS, the Board of Directors of the Corporation desires to amend the Plan to increase the
size of the stock pool available under the Plan to 7,525,040 shares, after giving effect to the Financing, the Series II Exchange and the Related Transactions (including the Reverse Stock Split). 
 NOW, THEREFORE, subject to approval of the Corporation’s stockholders, the Plan is amended as follows: 
 Section 2 of the Plan, “Stock Subject to Plan,” is hereby amended by deleting the number “68,272,380” in the third

Financing, the Series II Exchange and the Related Transactions (including the Reverse Stock Split). 
 The first sentence of
Section 2 of the Plan, “Stock Subject to Plan,” is deleted in its entirety and replaced with the following: 
 Subject to the provisions of Section 14 hereof, the stock to be subject to options or other awards under the Plan shall be the Company’s authorized Common Stock, $.001 par value per share (the “Common Shares”).

 INCENTIVE STOCK OPTION AGREEMENT 
 THIS AGREEMENT, made this      day of
            , by and between Optical Solutions, Inc., a Minnesota corporation (the “Company”), and
                     (“Optionee”). 
 WITNESSETH, THAT: 
 WHEREAS, the Company pursuant to its 1997 Long-Term Incentive
and Stock Option Plan wishes to grant this stock option to Optionee. 
 NOW, THEREFORE, in consideration of the premises and of
the mutual covenants herein contained, the parties hereto hereby agree as follows: 
  

	1.	Grant of Option. 

 The
Company hereby grants to Optionee, on the date set forth above, the right and option (hereinafter called “the Option”) to purchase all or any part of an aggregate of
             shares of Common Stock, no par value (the “Common Shares”), at the price of $            
per share on the terms and conditions set forth herein. This option is intended to be an incentive stock option within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). 
  

	2.	Duration and Exercisability. 

 (a) This option shall in all events terminate ten (10) years after the date of grant. Commencing immediately upon the date of grant and subject to the other terms and conditions set forth herein, this option may be exercised by
Optionee in cumulative installments as follows: 
  

			
	 On or after each of the
 following dates
	  	 Cumulative number of shares as
 to which option is exercisable

	  
 __________
	  	             Shares

 (b) During the lifetime of Optionee, the option shall be exercisable only by Optionee
and shall not be assignable or transferable by Optionee, other than by will or the laws of descent and distribution. 
  

	3.	Effect of Termination of Employment. 

 (a) In the event that Optionee shall cease to be employed by the Company or its subsidiaries, if any, for any reason other than Optionee’s serious misconduct or Optionee’s death or disability
(as such term is defined in Section 3(c) hereof), Optionee shall have the right to exercise the option at any time within one (1) month after such termination of employment to the extent of the full number of shares Optionee was entitled
to purchase under the option on the date of termination, subject to the condition that no option shall be exercisable after the expiration of the term of the option. 

 (b) In the event that Optionee shall cease to be employed by the Company or its
subsidiaries, if any, by reason of Optionee’s serious misconduct during the course of employment, including but not limited to wrongful appropriation of the Company’s funds, or in the event that Optionee violates the covenants set forth in
Section 5 hereof, the option shall be terminated as of the date of the misconduct. 
 (c) If Optionee shall die while in the
employ of the Company or a subsidiary, if any, or within one (1) month after termination of employment for any reason other than serious misconduct or if employment is terminated because Optionee has become disabled (within the meaning of Code
Section 22(e)(3)) while in the employ of the Company or a subsidiary, if any, and Optionee shall not have fully exercised the option, such option may be exercised at any time within twelve (12) months after Optionee’s death or date of
termination of employment for disability by Optionee, personal representatives or administrators, or guardians of Optionee, as applicable, or by any person or persons to whom the option is transferred by will or the applicable laws of descent and
distribution, to the extent of the full number of shares Optionee was entitled to purchase under the option on the date of death, termination of employment, if earlier, or date of termination for such disability and subject to the condition that no
option shall be exercisable after the expiration of the term of the option. 
  

	4.	Manner of Exercise. 

 (a)
The option can be exercised only by Optionee or other proper party by delivering within the option period written notice to the Company at its principal office. The notice shall state the number of shares as to which the option is being exercised
and be accompanied by payment in full of the option price for all shares designated in the notice. 
 (b) Optionee may pay the
option price in cash, by check (bank check, certified check or personal check) or by money order. 
  

	5.	Covenant Not to Compete. 

 Optionee hereby agrees to a covenant not to compete pursuant to the terms and conditions hereinafter set forth. The covenant not to compete shall have a term beginning on the date hereof and ending on the date that (a) is one
(1) year after the date that Optionee has exercised this option or (b) is one (1) year after the date of the termination of Optionee’s employment with the Company for any reason whatsoever, whichever is longer. The covenant not
to compete shall apply to the same geographical area in which Optionee worked on behalf of the Company at any time during the one-year period preceding Optionee’s termination of employment with the Company. 
 Optionee further agrees that during the term of said covenant he or she shall not, directly or indirectly, engage in any business activity
on his or her own behalf or as a partner, shareholder (except by ownership of less than five percent (5%) of the outstanding stock of a publicly held corporation), director, trustee, principal, agent, employee, consultant or otherwise of any
person or entity which is in any respect in competition with or competitive with the Company, or solicit, entice or induce any employee or representative of the Company to engage in any such activity.

  

 2 

 
Optionee also agrees that during the term of said covenant he or she shall not directly or indirectly solicit, entice or induce (or assist any other person or entity in soliciting, enticing or
inducing) any customer or potential customer (or agent, employee or consultant of any customer or potential customer) with whom Optionee had contact in the course of his or her employment with the Company to deal with a competitor of the Company.

 If any court of competent jurisdiction shall determine that the foregoing covenants are invalid in any respect, the parties
hereto agree that any court so holding may limit such covenant either or both in time, in area or in any other manner which the court determines such that the covenant shall be enforceable against Optionee. Optionee acknowledges that the remedy of
law for any breach of the foregoing covenants will be inadequate, and that the Company shall be entitled, in addition to any remedy of law, to preliminary and permanent injunctive relief. 
  

	6.	Miscellaneous. 

 This
option is issued pursuant to the Company’s 1997 Long Term Incentive and Stock Option Plan and is subject to its terms. The terms of the Plan are available for inspection during business hours at the principal offices of the Company. 

This Agreement shall not confer on Optionee any right with respect to continuance of employment by the Company or any of its
subsidiaries, nor will it interfere in any way with the right of the Company to terminate such employment at any time. Optionee shall have none of the rights of a shareholder with respect to shares subject to this option until such shares shall have
been issued to Optionee upon exercise of this option. 
 The exercise of all or any parts of this option shall only be effective
at such time that the sale of Common Shares pursuant to such exercise will not violate any state or federal securities or other laws. 
 If there shall be any change in the Common Shares of the Company through merger, consolidation, reorganization, recapitalization, dividend in the form of stock (of whatever amount), stock split or other change in the corporate structure of
the Company, and all or any portion of the option shall then be unexercised and not yet expired, then appropriate adjustments in the outstanding option shall be made by the Company, in order to prevent dilution or enlargement of option rights. Such
adjustments shall include, where appropriate, changes in the number of shares of Common Shares and the price per share subject to the outstanding option. 
 The Company shall at all times during the term of the option reserve and keep available such number of shares as will be sufficient to satisfy the requirements of this Agreement. 
 If Optionee shall dispose of any of the Common Shares of the Company acquired by Optionee pursuant to the exercise of the option within two
(2) years from the date this option was granted or within one (1) year after the transfer of any such shares to Optionee upon exercise of this option, then, in order to provide the Company with the opportunity to claim the benefit of any
income tax deduction which may be available to it under the circumstances, Optionee shall promptly notify the Company of the dates of acquisition and disposition of such shares, the number of shares so disposed of, and the consideration, if any,
received for such shares. In order to comply with all applicable federal or state income tax laws or regulations, the Company may

  

 3 

 
take such action as it deems appropriate to insure (i) notice to the Company of any disposition of the Common Shares of the Company within the time periods described above and
(ii) that, if necessary, all applicable federal or state payroll, withholding, income or other taxes are withheld or collected from Optionee. 
 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed on the day and year first above written.

under the Securities Act or under the securities or blue sky laws of any state or foreign jurisdiction; and that such securities must be held indefinitely unless they are subsequently registered under the Securities Act and any applicable state
securities or blue sky laws, or unless, in the opinion of counsel reasonably acceptable to the Company, an exemption from registration is available thereunder. Optionee acknowledges that all financial and other information pertaining to the

(ii) violate or cause the Company to violate the Securities Act, the rules and regulations promulgated thereunder or any other federal or state law. 
 4. Tax Consultation. Optionee understands that Optionee may suffer adverse tax consequences as a result of Optionee’s purchase or disposition of the Shares. Optionee represents that Optionee
has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares and that Optionee is not relying on the Company for any tax advice. 
 5. Interpretation. Any dispute regarding the interpretation of this Notice of Exercise shall be submitted by Optionee
or by the Company forthwith to the Company’s Board of Directors, which shall review such dispute. The resolution of such a dispute by the Board shall be final and binding on the Company and the Optionee. 
 6. Delivery of Payment. Optionee herewith delivers to the Company the full Option Price (as defined in the Stock
Option Agreement) for the Shares.

 2.1 Temporary Space. During the initial five months of the Lease Term, Landlord shall permit Tenant to use approximately 20,000 square feet of vacant space at 1039 North McDowell Boulevard for

square foot per month on the entire Temporary Space in addition to all Operating Expenses relating to the Temporary Space, all pro rated on a per diem basis. Landlord’s acceptance of such payments shall not limit Landlord’s other rights
and remedies with respect to recovering possession of the Temporary Space. 
 3. ACCEPTANCE OF PREMISES. Tenant hereby
acknowledges that the Premises are fully completed and are suitable for Tenant’s purposes, that the Building, the Common Areas, and the Premises are in good and satisfactory condition. Tenant is accepting the Premises in its current condition

 4. RENT. All amounts due hereunder from Tenant to Landlord (other than the Security
Deposit), whether designated as Base Rent, Additional Rent, Tenant Improvement Loan Repayment, late charges, interest or otherwise, shall be deemed “rent” hereunder. From the Commencement Date, Tenant will pay Landlord,
without prior notice, demand, offset or deduction (except as expressly provided herein), the following rent: 
 4.1 Base
Rent. Subject to the provisions of Paragraph 25.10, Tenant will pay the Base Rent (prorated for any partial month) in advance on the first day of each month during the term hereof. 
 4.2 Additional Rent. Tenant shall pay Tenant’s Share of Operating Expenses. The term “Operating
Expenses” is defined in Exhibit A. For partial years, Operating Expenses will be calculated on a calendar-year basis, and then prorated. Tenant shall pay monthly installments of Operating Expenses on the first day of each month, in
amounts specified in good faith and in reasonable detail by Landlord from time to time, which, by the end of each calendar year (or by the Expiration Date, if earlier), will total Landlord’s estimate of Operating Expenses paid for such year. As
soon as is reasonably practicable after the end of each calendar year during which Tenant paid Operating Expenses based on Landlord’s estimates as provided above, but in no case later than April 30 of the succeeding year, Landlord will
furnish Tenant a statement of Operating Expenses for such year showing in reasonable detail the components of Operating Expenses. Any amounts owing for that year shall, within thirty (30) days, be paid by Tenant to Landlord. Any amounts
overpaid shall, at Landlord’s option, be credited against the next installment(s) of estimated Operating Expenses due from Tenant, or be refunded to Tenant within 30 days after determination of such overpayment. The parties’ obligations
with respect to payment or refund of any deficiency or overpayment shall survive termination or expiration of this Lease. 
 4.3 Tenant’s Right to Audit Operating Expenses. Tenant shall have the right, to be exercised not more than once during any calendar year, by delivery of written notice to Landlord within one hundred eighty (180) days after
Landlord’s final statement of Operating Expenses, to audit Operating Expenses for the prior year, and to examine Landlord’s records relating to the same. Any such audit shall be conducted during the normal business hours of Landlord and at
Landlord’s office upon not less than thirty (30) days advance written notice. Such audit and examination shall be conducted by Tenant’s employees or an independent certified public accountant which shall not be compensated for such
audit and review on a contingency basis. No audit may be conducted at any time Tenant is in breach of its obligations under this Lease, after notice and expiration of any applicable cure period. Provided Landlord reasonably cooperates with
Tenant’s audit, any audit report must be delivered to Landlord within ninety (90) days after commencement of the audit. The costs of any such audit shall be borne by Tenant, provided, however, that in the event such audit reveals that the
amounts charged to Tenant were more than five percent (5%) greater than the amounts permitted by this Lease to be charged to Tenant, then Landlord shall pay the reasonable costs of that audit, and the reconciliation payment contemplated in
Paragraph 4.2 shall be made promptly thereafter. 
 5. SECURITY DEPOSIT. To secure its obligations under this Lease,
Tenant shall deliver to Landlord the Security Deposit. Landlord currently holds a Security Deposit of $200,000 under the Existing Lease. Landlord shall hold and apply such amount as the Security

  

 3 

 
Deposit hereunder. Tenant shall deliver the remainder of the Security Deposit to Landlord upon its execution and delivery of this Lease. If Tenant defaults on any provision of this Lease,
Landlord may, without prejudice to any other remedy it has, apply all or part of the Security Deposit to (a) any rent or other sum in default; (b) any amount that Landlord may spend or become obligated to spend in exercising
Landlord’s rights under Paragraph 18; and/or (c) any expense, loss, or damage that Landlord may suffer because of Tenant’s default. Tenant waives the provisions of California Civil Code section 1950.7, and all other provisions of law
now in force or that become in force after the date of execution of this Lease, that provide that Landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of Rent, to repair damage caused by
Tenant, or to clean the Premises. Landlord and Tenant agree that Landlord may, in addition, claim those sums reasonably necessary to compensate Landlord for any other foreseeable or unforeseeable loss or damage caused by the act or omission of
Tenant or Tenant’s officers, agents, employees, independent contractors, or invitees. If Landlord disposes of its interest in the Premises, Landlord shall deliver or credit the Security Deposit to Landlord’s successor in interest in the
Premises and thereupon be relieved of further responsibility with respect to the Security Deposit. Landlord may commingle the Security Deposit with other funds. Following any application of the Security Deposit, Tenant shall, within five
(5) days following Landlord’s demand, restore the Security Deposit to its full original amount, and Tenant’s failure to restore the Security Deposit shall be deemed an Event of Default under this Lease without further notice or cure
period. Subject to applicable bankruptcy law, in the event of bankruptcy or other insolvency proceedings filed by or against Tenant, the Security Deposit shall be deemed to be applied first to the payment of Rent and other charges due Landlord for
all periods prior to the effective date of such proceedings. If Tenant is not in default at the termination of this Lease, Landlord will return any remaining Security Deposit, without interest, within thirty (30) days after Tenant’s
vacation and surrender of the Premises, provided Landlord may withhold a reasonable portion of the Security Deposit to cover any remaining obligations of Tenant under Paragraph 4.2 above. Tenant shall not assign or encumber the Security Deposit or
attempt to do so, and Landlord shall not be bound by any such assignment or encumbrance. Regardless of any assignment, Landlord may return the Security Deposit to the original Tenant. Interest shall not accrue on the Security Deposit. 
 5.1 Letter of Credit. In lieu of $300,000 of the cash Security Deposit (the “Letter of Credit Amount”),
Tenant may deliver to Landlord a standby, irrevocable, unconditional Letter of Credit (the “Letter of Credit”) in the form set forth on Exhibit G hereto and containing the terms required herein, in the face amount equal to
the Letter of Credit Amount. The Letter of Credit shall secure and serve as collateral for the full performance by Tenant of all of its obligations under this Lease and for all losses and damages Landlord may suffer as a result of any Event of
Default by Tenant under this Lease, including, but not limited to, any post-lease termination damages under section 1951.2 of the California Civil Code. Landlord hereby approves of Silicon Valley Bank as issuer of the Letter of Credit. Tenant shall
cause the Letter of Credit to be continuously maintained in effect (whether through replacement, renewal or extension) in the Letter of Credit Amount through the date that is thirty (30) days after the scheduled expiration date of the Lease
Term (the “Final LC Expiration Date”). If the Letter of Credit held by Landlord expires earlier than the Final LC Expiration Date (whether by reason of a stated expiration date or a notice of termination or non-renewal given
by the issuing bank), Tenant shall deliver a new Letter of Credit or certificate of renewal or extension to Landlord not later than thirty (30) days prior to the expiration date of the Letter of Credit then

  

 4 

 
held by Landlord. Any renewal or replacement Letter of Credit shall comply with all of the provisions of this Paragraph 5, shall be irrevocable, transferable and shall remain in effect (or be
automatically renewable) through the Final LC Expiration Date upon the same terms as the expiring Letter of Credit or such other terms as may be acceptable to Landlord in its sole discretion. 
 5.2 Drawings under Letter of Credit. Landlord shall have the immediate right to draw upon the Letter of Credit, in whole or in part,
at any time and from time to time: (i) if an Event of Default occurs; or (ii) if the Letter of Credit held by Landlord expires earlier than the Final LC Expiration Date (whether by reason of a stated expiration date or a notice of
termination or non-renewal given by the issuing bank), and Tenant fails to deliver to Landlord, at least thirty (30) days prior to the expiration date of the Letter of Credit then held by Landlord, a renewal or substitute Letter of Credit that
is in effect and that complies with the provisions of this Paragraph 5. No condition or term of this Lease shall be deemed to render the Letter of Credit conditional to justify the issuer of the Letter of Credit in failing to honor a drawing upon
such Letter of Credit in a timely manner. Tenant hereby acknowledges and agrees that Landlord is entering into this Lease in material reliance upon the ability of Landlord to draw upon the Letter of Credit upon the occurrence of any Event of Default
by Tenant under this Lease or upon the occurrence of any of the other events described above in this Paragraph 5. 
 5.3 Use
of Proceeds by Landlord. The proceeds of the Letter of Credit shall constitute Landlord’s sole and separate property (and not Tenant’s property or the property of Tenant’s bankruptcy estate) and Landlord may immediately upon any
draw (and without notice to Tenant) apply or offset the proceeds of the Letter of Credit: (i) against any Rent payable by Tenant under this Lease that is not paid when due; (ii) against all costs (including reasonable attorneys’ fees
and costs), losses and damages that Landlord has suffered or that Landlord reasonably estimates that it may suffer as a result of any Event of Default by Tenant under this Lease, including any damages arising under section 1951.2 of the California
Civil Code following termination of the Lease; and (iii) against any other amount that Landlord may spend or become obligated to spend by reason of Tenant’s default. Provided Tenant has performed all of its obligations under this Lease,
Landlord agrees to pay to Tenant within thirty (30) days after the Final LC Expiration Date the amount of any proceeds of the Letter of Credit received by Landlord and not applied as allowed above; provided, that if prior to the Final LC
Expiration Date a voluntary petition is filed by Tenant or any Guarantor, or an involuntary petition is filed against Tenant or any Guarantor by any of Tenant’s or Guarantor’s creditors, under the Federal Bankruptcy Code, then Landlord
shall not be obligated to make such payment in the amount of the unused Letter of Credit proceeds until either all preference issues relating to payments under this Lease have been resolved in such bankruptcy or reorganization case or such
bankruptcy or reorganization case has been dismissed, in each case pursuant to a final court order not subject to appeal or any stay pending appeal. 
 5.4 Additional Covenants of Tenant. If, as result of any application or use by Landlord of all or any part of the Letter of Credit, the amount of the Letter of Credit shall be less than the Letter
of Credit Amount, Tenant shall, within ten (10) Business days thereafter, provide Landlord with cash or additional letter(s) of credit in an amount equal to the deficiency (or a replacement letter of credit in the total Letter of Credit
Amount), and any such additional (or replacement) letter of credit shall comply with all of the provisions of this Paragraph 5, and if

  

 5 

 
Tenant fails to comply with the foregoing, notwithstanding anything to the contrary contained in this Lease, the same shall constitute an uncurable Event of Default by Tenant. If Tenant deposits
cash to make up the deficiency, Tenant may at any time thereafter substitute Letter(s) of Credit complying with the provisions of this Paragraph 5 for such cash deposit, in which case Landlord shall promptly return such cash deposit to Tenant.
Tenant further covenants and warrants that it will neither assign nor encumber the Letter of Credit or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance, attempted assignment
or attempted encumbrance. 
 5.5 Transfer of Letter of Credit. Landlord may, at any time and without notice to Tenant and
without first obtaining Tenant’s consent thereto, transfer all or any portion of its interest in and to the Letter of Credit to the transferee of Landlord’s interest in the Building or Landlord’s mortgagee and/or to have the Letter of
Credit reissued in the name of Landlord’s mortgagee. If Landlord transfers its interest in the Building, Landlord shall transfer the Letter of Credit (and any proceeds thereof then held by Landlord) to the transferee, and Landlord shall,
without any further agreement between the parties hereto, thereupon be released by Tenant from all future liability with respect to the transferred Letter of Credit. The provisions hereof shall apply to every transfer or assignment of the Letter of
Credit to a new landlord. In connection with any such transfer of the Letter of Credit by Landlord, Tenant shall, at Tenant’s sole cost and expense, execute and submit to the issuer of the Letter of Credit such applications, documents and
instruments as may be necessary to effectuate such transfer. 
 5.6 Nature of Letter of Credit. Landlord and Tenant
(1) acknowledge and agree that in no event or circumstance shall the Letter of Credit or any renewal thereof or substitute therefor or any proceeds thereof be deemed to be or treated as a “security deposit” under any Law applicable to
security deposits in the commercial context including Section 1950.7 of the California Civil Code, as such section now exist or as may be hereafter amended or succeeded (“Security Deposit Laws”), (2) acknowledge and
agree that the Letter of Credit (including any renewal thereof or substitute therefor or any proceeds thereof) is not intended to serve as a security deposit, and the Security Deposit Laws shall have no applicability or relevancy thereto, and
(3) waive any and all rights, duties and obligations either party may now or, in the future, will have relating to or arising from the Security Deposit Laws. Tenant hereby waives the provisions of Section 1950.7 of the California Civil
Code and all other provisions of Law, now or hereafter in effect, which (i) establish the time frame by which Landlord must refund a security deposit under a lease, and/or (ii) provide that Landlord may claim from the Security Deposit only
those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by Tenant or to clean the Premises, it being agreed that Landlord may, in addition, claim those sums specified in this Paragraph 5.3 above.

 6. SERVICES AND UTILITIES. Tenant shall contract for, and pay for, janitorial services for the Premises using such
janitorial contractor as Landlord shall approve, which approval shall not be unreasonably withheld, conditioned, or delayed. Tenant shall pay prior to delinquency for all water, gas, light, heat, power, electricity, telephone, janitorial service,
trash pick-up, sewer charges, and all other services supplied to or consumed on the Premises, and all taxes and surcharges thereon. If such utilities or services are not separately metered or provided, Tenant shall pay Tenant’s Share of such
charges. Tenant shall pay to Landlord Tenant’s Share of the cost of all utilities supplied in connection with the operation of the Common Areas. 
  

 6 

 7. USE OF PREMISES. 
 7.1 Permitted Use. Tenant will use and occupy the Premises only for the purpose set forth in Paragraph 1.5 and no other, using and
maintaining the Premises in a careful, sanitary and proper manner. Subject to the waiver set forth in Paragraph 15, Tenant will pay for any damage to any part of the Premises or Building or Project caused by any negligence or willful act by Tenant
or Tenant’s employees, agents, contractors or invitees. Tenant will comply with the Project’s Rules and Regulations and the CC&Rs and will not cause anywhere in the Building or Project, or permit in the Premises, (i) any activity
or thing contrary to applicable law, ordinance, regulation, restrictive covenant, or insurance regulation whether now in force or hereafter in force; or which is in any way extra-hazardous or could jeopardize the coverage of normal insurance
policies or increase their cost; (ii) waste or nuisance, or any activity causing odors, noise or vibration perceptible outside the Premises; (iii) cooking or heating food, except for incidental use, solely for Tenant’s employees, of
microwave ovens and beverage-brewing devices, provided that the foregoing do not use a flame and are approved by Underwriters Laboratories for residential use; (iv) overloading the floors or the structural or mechanical systems of the
Building; or (v) obstruct or interfere with the rights of other tenants or users of the Building or the Project. Tenant shall not erect or place any item in or upon the Common Areas. Tenant shall store its waste either inside the Premises or in
its own dumpsters located within outside trash enclosures. Except as expressly permitted in the Addendum, Tenant shall not store, place or maintain any garbage, trash, rubbish, other refuse or Tenant’s personal property in any area of the
Common Area or exterior of the Premises at any time, without Landlord’s prior written consent. Tenant at its sole expense shall be responsible to maintain and keep the designated trash enclosures free of garbage, trash, rubbish, other refuse or
personal property. 
 7.2 Compliance with Laws. Tenant shall at Tenant’s sole cost and expense faithfully observe
and promptly comply with all local, state and federal laws, statutes, ordinances and governmental resolutions, orders, rules, regulations and requirements (including, by way of example, building codes, Title 24, and the Americans With Disabilities
Act of 1990) as amended and with the requirements of any board of fire underwriters (or other similar body now or hereafter constituted) whether now in force or which may hereafter be in force with respect to the use, occupancy, modification or
possession of the Premises and all business conducted in the Premises. Tenant shall also comply with the CC&Rs and any other covenant, condition or restriction affecting the Building or the Project. Without limiting the generality of the
provisions of this Paragraph 7, as between Landlord and Tenant, Tenant shall make all alterations to the Premises, whether major or minor, reasonably necessary to comply at any time with the requirements referred to in this Paragraph 7. 

8. BROKERS. Landlord and Tenant warrant that they have had no dealing with any finder, broker or agent other than the Brokers in
connection with this Lease. Tenant will indemnify, defend and hold Landlord harmless from and against any and all costs, expenses or liability for commissions or other compensation or charges claimed by any finder, broker or agent other than the
Brokers based on dealings with Tenant with respect to this Lease. Landlord will indemnify, defend and hold Tenant harmless from and against any and all costs, expenses or liability for commissions or other compensation or charges claimed by any
finder, broker or agent other than the Brokers based on dealings with Landlord with respect to this Lease.

  

 7 

 
Landlord will pay compensation, if any, owing to the Brokers or any other broker representing Landlord pursuant to a separate agreement. 
 9. TENANT’S TAXES. In addition to Tenant’s obligations to pay Real Property Taxes as set forth in Paragraph 4.2, Tenant
shall be liable for and shall pay, before delinquency, all fees, charges, taxes levied or assessed against or attributable to any personal property or trade fixtures in the Premises. If any such taxes or value are included in Landlord’s taxes,
Landlord shall immediately provide Tenant with notice of and an opportunity to investigate such inclusion. If, after such notice, Tenant fails to successfully protest or pay any such taxes included in Landlord’s taxes, Landlord may pay them
regardless of their validity (under proper protest, if requested by Tenant), and Tenant upon demand will reimburse Landlord. 
 10. ALTERATIONS, REPAIRS AND MAINTENANCE. 
 10.1 Repairs and Maintenance. 
 (a) Landlord shall at its expense and not as an Operating Expense, repair and maintain the foundation and structural
portions of the Building. Landlord shall, as an Operating Expense (except as excluded herein), repair and maintain the exterior roof, the nonstructural components of the exterior walls of the Building and the improvements within the Common Areas
including without limitation any sidewalks, landscaping (including but not limited to irrigation systems and backflow prevention devices), parking areas, fences and signs (other than Tenant’s signs). Subject to the waivers set forth in
Paragraph 15, to the extent any such maintenance and repairs are caused in part or in whole by the act, neglect or omission of any duty by Tenant or Tenant’s employees, agents, contractors or invitees, then Tenant shall pay to Landlord, as
Additional Rent, the entire cost of such maintenance and repairs. Landlord shall not, however, be obligated to paint the interior surface of exterior walls, ceiling or doors, nor shall Landlord be required to maintain, repair or replace interior
doors, interior glass, skylights (if any) or plate glass. Landlord shall have no obligation to make repairs under this Paragraph 10.1(a) until a reasonable time after receipt of written notice of the need for such repairs (or verbal notice in the
event of an emergency). Landlord shall maintain, repair or patch the roof membrane as an Operating Expense, and Tenant shall pay Tenant’s Share of the cost thereof, pursuant to Paragraph 4.2 above. Landlord shall have no obligation to alter,
remodel, improve, decorate or paint the Premises or any part thereof, except as expressly provide in Exhibit C. Subject to Paragraphs 13(b) and 25.19 and other express provisions of this Lease, there shall be no abatement of rent and no
liability of Landlord by reason of any injury to or interference with Tenant’s business arising from the making of any repairs, alterations or improvements in or to any portion of the Building, the Premises or parking areas or in or to
fixtures, appurtenances and equipment therein. Landlord shall use commercially reasonable efforts to coordinate such work with Tenant and perform such work in such a manner as to reasonably minimize the disruption of Tenant’s use of the
Premises. Tenant expressly waives the benefits of any statute (including, without limitation, the provisions of subsection 1 of Section 1932, Section 1941 and Section 1942 of the California Civil Code and any similar law, statute or
ordinance now or hereafter in effect) which would otherwise afford Tenant the right to make repairs at Landlord’s expense (or to deduct the cost of such repairs from rent due hereunder) or to terminate this Lease, except as expressly provided
in this Lease. Notwithstanding the foregoing, in the event Landlord materially defaults in its obligation to repair or maintain the Building or the Premises as required,

  

 8 

 
then Tenant may effect said repair or maintenance and deduct from rent an amount not to exceed the lesser of $75,000 or the reasonable and verifiable costs of said repair or maintenance,
provided that (A) not less than thirty (30) days (or such shorter time as reasonably required in the event of a repair or maintenance problem that materially impacts Tenant’s operations within the Premises) prior to effecting
such repair or maintenance, Tenant delivers to Landlord written notice of the need for such repair or maintenance and of Tenant’s intention to effect such repair or maintenance, and (B) within thirty (30) days following Tenant’s
notice (or such shorter time as reasonably required in the event of a repair or maintenance problem that materially impacts Tenant’s operations within the Premises), Landlord fails to effect such repair or maintenance or, if such repair or
maintenance requires longer than thirty (30) days to complete, Landlord has failed to take reasonable and diligent steps to effect such repair or maintenance and to proceed to pursue such repair or maintenance to completion. 
 (b) Except to the extent included within Landlord’s maintenance and repair obligations under Paragraph 10.1(a)
above, Tenant, at Tenant’s sole cost and expense, shall keep, maintain and preserve the Premises in good condition and repair (reasonable wear and tear excepted) and shall, promptly make all non-structural repairs and replacements to the
Premises and every part thereof, including but not limited to floors, ceilings, interior windows and doors, skylights (if any), interior walls, and the interior surfaces of the exterior walls, plumbing, heating, air conditioning and ventilating
equipment, telecommunications equipment and intrabuilding network cabling, and electrical and lighting facilities and equipment including circuit breakers. Tenant shall have access to the roof of the Building to perform its HVAC and related
maintenance obligations. In the event Tenant fails to perform Tenant’s obligations under this Paragraph, Landlord shall give Tenant notice to do such acts as Landlord deems are reasonably required to so maintain the Premises. If Tenant, within
ten (10) days after notice from Landlord, fails to commence to do the work and diligently prosecute it to completion, then Landlord shall have the right (but not the obligation) to do such acts and expend such funds at the expense of Tenant as
are reasonably required to perform such work. Any reasonable amount so expensed by Landlord shall be paid by Tenant promptly after demand as Additional Rent. Subject to Paragraphs 13(b) and 25.19 and other express provisions of this Lease, Landlord
shall have no liability to Tenant for any damage, inconvenience or interference with the use of the Premises by Tenant as a result of performing any such work. 
 10.2 Alterations. 
 (a) Tenant will not make or
permit alterations, improvements or additions (including fixtures) in or to the Premises (collectively “Alterations”) without Landlord’s prior, written consent, which shall not be unreasonably withheld, conditioned, or
delayed. Notwithstanding the foregoing, (i) minor alterations such as repainting and carpeting, or alterations with an aggregate cost of less than $25,000 per project, and (ii) which do not affect structural components or building systems,
shall not require Landlord’s consent hereunder, but all work in connection therewith shall be conducted and completed in a workmanlike manner and in such a manner as to not materially interfere with the use of the Common Areas or any other
portion of the Project by Landlord or its other tenants. Tenant’s request for such consent shall be in writing, accompanied by proposed detailed plans and specifications. Tenant may engage its own contractors to perform remodel work upon
written approval by Landlord, which shall not be unreasonably withheld, conditioned, or delayed. Landlord may charge Tenant for Landlord’s

  

 9 

 
reasonable out-of-pocket costs in reviewing and supervising such planning and, if Landlord is managing the construction work, a construction management fee not to exceed three percent
(3%) of Tenant’s planning and construction costs. Any and all plans must be submitted to Landlord for approval and building permits must be obtained prior to commencement of any construction remodeling. All Alterations constructed by
Tenant shall remain the property of Tenant during the Lease Term. Subject to Paragraph 23, at the expiration or sooner termination of the Lease Term, all Alterations shall be surrendered to Landlord as a part of the realty and shall then become
Landlord’s property. Tenant will promptly notify Landlord of the reasonably estimated value thereof for insurance and tax purposes, provided that Tenant shall not have any liability to Landlord for such estimate. 
 (b) Tenant shall give Landlord written notice not less than five (5) days notice prior to the commencement of any
work in the Premises by or on behalf of Tenant, and Landlord shall have the right to post notices of non-responsibility in or on the Premises or the Building as provided by law. All Alterations, repairs and replacements by Tenant shall be made,
constructed and installed in accordance with all applicable laws, rules and ordinances (and Tenant shall perform all work necessary to comply fully with all laws, ordinances and regulations necessitated by the Alterations, whether structural or
non-structural, within or without the Premises) and the requirements of any insurance carrier, and shall be of a quality and class at least equal to the original work, performed in a good and workmanlike manner with grades of materials approved by
Landlord (if applicable). Tenant shall ensure that all work is performed in a manner that does not obstruct access to or through the common areas and that does not interfere either with other tenants’ use of their premises or with any other
work being undertaken in the Building. All work which may involve noise, odors or vibrations which may be perceptible outside the Premises and disturbs other tenants of the Project shall be performed at times other than normal business hours. Tenant
shall take all measures necessary to ensure that labor peace is maintained at all times. Before construction begins, Tenant shall deliver to Landlord reasonable evidence that damage to, or destruction of, the Alterations and Premises during
construction will be covered either by the policies that Tenant is required to carry under Paragraph 14 or by a policy of builder’s all-risk insurance in an amount approved by Landlord. If Landlord requires Tenant to provide builder’s
all-risk insurance for the proposed Alterations, Tenant shall provide to Landlord a copy of the policy, any endorsements or an original certificate of insurance that complies with Paragraph 14. Tenant shall cause each contractor and subcontractor to
maintain all workers’ compensation insurance required by law and liability insurance (including property damage) in amounts reasonably required by Landlord. Tenant will give Landlord opportunity to supervise all work. Tenant shall provide
Landlord with permit drawings, as-built CAD drawings (if the Alterations require a building permit or Tenant is preparing same for its own account), job cards and temporary certificates of occupancy for all Alterations promptly upon their
completion. Should Tenant make any Alterations without Landlord’s prior written approval, or in violation of such approval or the requirements of this Paragraph 10.2, Landlord may, at any time during the Lease Term, either remove any part or
all of the same on Tenant’s behalf and at Tenant’s expense, or require that Tenant do so. 
 (c)
If during the Lease Term, any alteration, addition or change of any sort, whether structural or otherwise to all or any portion of the Premises or Building is required by law (including, but not limited to, alterations required by the Americans with
Disabilities Act of 1990 or any amendments thereto or any regulations prorogated thereunder (collectively the

  

 10 

 
“ADA”) because of (i) Tenant’s use or occupancy of the Premises or change of use or occupancy of the Premises, (ii) Tenant’s application for any permit
or governmental approval, (iii) Tenant’s construction or installation of any leasehold improvements or trade fixtures, (iv) any violation by Tenant of any Law (including any requirement of the ADA), (v) any special use of the
Premises or any part thereof by Tenant or any subtenant or assignee of Tenant (including, but not limited to any use for a facility which constitutes, or if open to the public would generally constitute a “place of public accommodation”
under the ADA requirements), or (vi) any special needs of the employees of Tenant or any assignee or subtenant of Tenant, then Tenant shall promptly make the same at its sole cost and expense. Within ten (10) days after receipt, Tenant
shall notify Landlord in writing and provide Landlord with copies of (i) any notices alleging any violation of any Law relating to the Premises or Tenant’s occupancy or use of the Premises, including any notices alleging violation of the
Project or the ADA to any portion of the Project or the Premises; (ii) any claims made or threatened in writing regarding non-compliance with the ADA or any Law relating to the Project or the Premises; or (iii) any governmental or
regulatory actions or investigations instituted or threatened regarding non-compliance with the ADA or any Law relating to any portion of the Project or the Premises. 
 (d) If during the Lease Term, any alteration, addition or change to any structural portion of the Building (excluding
leasehold improvements) or to the Common Areas is required by local governmental authorities (including, but not limited to, on account of the ADA) other than as set forth in Paragraph 10.2(c) above, then Landlord shall perform the same and the cost
thereof shall be included within Operating Expenses subject to the limitations and amortization provisions set forth in Exhibit A. 
 11. LIENS. Tenant shall not permit any lien on any part of the Premises, Building or the Project allegedly resulting from any work or materials furnished or obligations incurred by or for Tenant.
Tenant shall discharge any such lien of record (including by recording a release bond) within fifteen (15) Business days after demand by Landlord. Neither this Lease, nor any request or consent of Landlord to the labor, materials or
obligations, is a consent to such a lien. Landlord may keep posted on the Premises any notices it deems necessary for protection from such liens. If Tenant fails to remove any such lien within fifteen (15) Business days after demand, Landlord
may cause such liens to be released by any means it deems proper, including payment, at Tenant’s expense and without affecting Landlord’s rights. 
 12. ENTRY. Landlord may enter any part of the Premises at all reasonable hours following not less than two (2) business days notice (or in any emergency or suspected emergency, at any hour and
without prior notice), to (a) inspect, test, clean, or make repairs, alterations and additions to the Building or the Premises as Landlord believes appropriate, or (b) provide any service which Landlord is now or hereafter obligated to
furnish to tenants of the Building or the Project, or (c) show the Premises to prospective lenders, purchasers or to prospective tenants, provided that Landlord may only show the Premises to prospective tenants during the last six
(6) months of the Lease Term or at any time an Event of Default by Tenant is occurring hereunder. Landlord shall exercise commercially reasonable efforts to minimize any disruptions to Tenant’s use of the Premises. Subject to Paragraphs
13(b) and 25.19 and other express provisions of this Lease, Tenant hereby waives any claim for abatement of rent or for damages for any injury, inconvenience to or interference, loss of occupancy or quiet enjoyment

  

 11 

 
caused by Landlord’s entry. Landlord shall at all times have keys to all exterior doors to the Premises. 
 13. INDEMNIFICATION AND EXCULPATION. 
 (a) Subject to
Paragraph 15, Tenant will indemnify, defend and hold and save Landlord and its employees, officers, directors, shareholders, managers, members and agents (each, together with Landlord, a “Landlord Indemnitee”) harmless from
all fines, suits, losses, costs, expenses, liabilities, claims, demands, actions, damages and judgments (“Liabilities”) suffered by, recovered from or asserted against any Landlord Indemnitee, of every kind and character, to
the extent resulting from: 
 (i) the operation, condition, maintenance, use or occupancy of the Premises,
except to the extent arising due to the gross negligence, fraud or willful misconduct of any Landlord Indemnitee or any breach or default by Landlord of any obligation on Landlord’s part to be performed under this Lease, 
 (ii) any bodily injury, death or property damage occurring in the Premises, except to the extent arising due to the
gross negligence, fraud or willful misconduct of any Landlord Indemnitee, 
 (iii) any act, omission or
negligence of Tenant, its employees, contractors or agents, or 
 (iv) any breach or Event of Default in
the performance in a timely manner of any obligation on Tenant’s part to be performed under this Lease. 
 (b) Subject to the provisions of this Paragraph 13 and except to the extent arising due to the gross negligence, fraud or willful misconduct of any Landlord Indemnitee, Tenant, as a material part of the consideration to Landlord,
hereby assumes all risk of damage to property or injury to persons, in, upon or about the Premises arising from any cause, and Tenant hereby waives, to the fullest extent permitted by law, all claims against the Landlord and Landlord’s
Indemnitees for personal injury or death, loss of, damage or destruction of any tangible or intangible property, including economic losses and consequential and resulting damages. 
 (c) Subject to Paragraph 15, Landlord will indemnify, defend and hold and save Tenant and its employees, officers,
directors, shareholders, managers, members and agents (each, together with Tenant, a “Tenant Indemnitee”) harmless from and against all Liabilities suffered by, recovered from or asserted against any Tenant Indemnitee, of
every kind and character, resulting from any injury or damage to person or property (i) within the Premises but only to the extent caused by the gross negligence, fraud or intentional misconduct of any Landlord Indemnitee (ii) outside the
Premises but only to the extent caused by the negligence, fraud or intentional misconduct of any Landlord Indemnitee or (iii) the material breach or default in the performance in a timely manner of any obligation on Landlord’s part to be
performed under this Lease.

 (d) If any such proceeding is brought, the indemnifying party will
retain counsel reasonably satisfactory to the indemnified party to defend the indemnified party at the indemnifying party’s sole cost and expense. All such costs and expenses, including reasonable attorneys’ fees and court costs, shall be
a demand obligation owing by the indemnifying party to the indemnified party. The indemnifying party’s obligations under this Paragraph 13 shall survive the termination or expiration of this Lease for a period of one (1) year. The
indemnification provisions herein are independent of the parties’ insurance obligations herein, and neither party’s obligation to indemnify shall be limited or modified by such party’s insurance coverage or obligations herein.

 14. INSURANCE. Tenant, during the term and any other period of occupancy, will, at its expense, maintain insurance
reasonably satisfactory to Landlord, but in no event less than: 
 (a) Commercial General Liability
insurance with not less than $3,000,000.00 coverage per occurrence, for bodily injury or death, and property damage and personal and advertising injury occurring in or about or related to the use of the Premises and Tenant’s business
operations, conduct and assumed liabilities including coverage for Tenant’s indemnification obligations herein. Such policy shall be on a form no less broad than the current ISO CG 00 01 (or equivalent) Tenant may satisfy this requirement via a
combination of primary Commercial General Liability insurance and excess umbrella coverage equaling or exceeding the required coverage limits. 
 (b) “All Risk” or “Special form” insurance (including earthquake coverage) for the full replacement cost of all Tenant’s property on the Premises and all fixtures and
leasehold improvements in the Premises, with no co-insurance. Unless this Lease is terminated upon damage or destruction, the proceeds of such insurance will be used to restore the foregoing. 
 (c) Worker’s Compensation (as required by state law) and Employer’s Liability insurance in the amount of not
less than $1,000,000. 
 (d) Business Income and extra expense insurance covering loss of rental income of
not less than twelve (12) months. 
 All policies required hereunder will be issued by carriers rated A-VII or better by
Best’s Key Rating Guide or otherwise reasonably acceptable to Landlord and licensed to do business in the State of California. Tenant’s general liability policies shall name Landlord, Landlord’s partners, Landlord’s managing
agent, Landlord’s lender (if any) and any other person or entity that Landlord may reasonably designate in writing from time to time as additional insureds and Tenant’s property insurance shall name Landlord as loss payee as its interest
shall appear with respect to the leasehold improvements in the Premises, but not Tenant’s property. Tenant’s general liability policy shall be primary and non-contributing with respect to any insurance Landlord may carry. No coverage
required herein may be cancelled or materially changed except upon fifteen (15) days prior written notice to Landlord. Tenant’s general liability policies shall include a separation of insureds or severability of interests provision. Prior
to expiration of such policies, and promptly upon any other request by Landlord, Tenant shall furnish Landlord with copies of policies, or evidence of insurance, evidencing maintenance and renewal of the required coverage on

  

 13 

 
ACORD 27 or other form acceptable to Landlord in its sole discretion, and a copy of the endorsement to or provision of Tenant’s liability policy showing the additional insureds. In the event
Tenant does not maintain said insurance, and Tenant fails to provide proof of such insurance within five (5) Business days after receipt of notice from Landlord of such failure, Landlord may, in its sole discretion and without waiving any other
remedies hereunder, procure said insurance and Tenant shall pay to Landlord as rent the cost of said insurance plus a ten percent (10%) administrative fee. If Landlord’s lender, insurance advisor or counsel reasonably determines at any
time that the amount of such coverage is not adequate, Tenant shall, after receipt of written notice from Landlord, increase such coverage to such amount as Landlord’s lender, insurance advisor or counsel reasonably deems adequate.
Tenant’s suppliers, contractors and vendors may be required to present to Landlord certificates of insurance showing adequate general liability coverage, as reasonably determined by Landlord, and naming Landlord as an additional insured. The
limit of such insurance shall not limit the liability of Tenant. 
 During the Lease Term, Landlord shall insure the Building
(excluding any property which Tenant is obligated to insure and excluding foundations) against damage with All-Risk, broad form insurance (including earthquake insurance as commercially reasonable) and commercial general liability insurance, all in
such amounts and with such deductibles as Landlord reasonably considers appropriate. Landlord may, but shall not be obligated to, obtain and carry any other form or forms of insurance as it or its Mortgagees may determine advisable. Landlord’s
insurance shall be reasonably comparable to the types and limits of coverage carried by institutional landlords of comparable buildings in the vicinity of the Project. Except in the event Tenant elects to restore the Premises pursuant to Paragraph
16.1 below, Tenant has no right to receive any proceeds from any insurance policies carried by Landlord. Notwithstanding anything in the foregoing to the contrary, however, Landlord may self-insure as to a portion of the earthquake coverage.

 If the acts or omissions of Tenant or Tenant’s employees, agents, contractors or invitees, whether or not Landlord has
consented to the same, increase the cost of Landlord’s insurance, Tenant will pay the full cost of any such increase as Additional Rent. 
 15. MUTUAL RELEASE/WAIVER OF SUBROGATION. Notwithstanding anything to the contrary set forth in this Lease, Landlord and Tenant each hereby release the other from any and all liability or
responsibility for any loss or damage to property located within the Premises, the Building, the Project, the Common Areas or any portions thereof, or any contents caused by fire or any other casualty, or accident during the Term of this Lease or
any extensions thereof, even if such fire, casualty, or accident may have been caused by the negligence (but not the gross negligence or willful misconduct) of the other party or one for whom such party may be responsible; provided, however, that
the foregoing release shall be effective only to the extent that the releasing party is either compensated for its loss by insurance proceeds or such party would have been compensated for its loss by insurance proceeds had it complied with the
insurance requirements imposed under Article 14. Inasmuch as the above mutual waivers will preclude the assignment of any aforesaid claim by way of subrogation (or otherwise) to an insurance company (or any other person), each party hereto hereby
agrees, if required by said policies, to give to each insurance company which has issued to it policies of fire and extended coverage insurance, and other insurance, written notice of the terms of said mutual waivers, and to have said insurance
policies properly endorsed, if necessary, to prevent the invalidation of said

  

 14 

 
insurance coverage by reason of said waivers. To the extent either party is waiving its subrogation rights or is required to obtain waivers of subrogation rights with respect to its insurance
policies, any such waiver by either party is expressly conditioned on (1) such a waiver not invalidating such party’s insurance policies and (2) the availability of waiver of subrogation rights under such insurance policies.

 16. DAMAGE OR DESTRUCTION. If the Building or the Premises or any part thereof are damaged by fire, flood or other
casualty, Tenant will promptly notify Landlord. 
 16.1 Cancellation of Lease; Restoration of Building. If the Building,
Premises and/or the Parking Area are substantially damaged by fire, flood or other casualty, Landlord shall provide the Tenant a written estimate of the period required to substantially restore the Building and Premises (including the leasehold
improvements) and the Parking Area as provided herein (“Repair Estimate”). If such the estimated restoration period exceeds one hundred twenty (120) days after the date of the casualty and such damage materially
interferes with Tenant’s use of and access to the Premises, then either party may terminate this Lease by notifying the other party within fifteen (15) days after the date of the Repair Estimate. In the event Landlord elects to terminate
this Lease, Tenant shall have the right within ten (10) days of receipt of the termination notice from Landlord to elect to restore the Premises and Building in which event this Lease shall continue in full force and effect, all insurance
proceeds available from the property insurance carried by Landlord with respect to the Building and Premises shall be made available to Tenant to make repairs, and Tenant shall proceed to make such repairs as soon as reasonably possible (or Landlord
may elect, in its sole discretion, to require Tenant to pay to Landlord within ten (10) days following written request therefor, or furnish evidence reasonably satisfactory to Landlord of Tenant’s ability to fund, that portion of the cost
of such repair or restoration which is not covered by insurance proceeds, in which event Landlord shall proceed to make such repairs). If Tenant does not give such notice within the ten (10) day period, this Lease shall be cancelled and
terminated as of the date of the occurrence of such damage. If this Lease is terminated, all insurance proceeds available from the fire and property damage insurance carried by Landlord pursuant to Paragraph 14 shall be paid to and become the
property of Landlord. If this Lease is not terminated, then within thirty (30) days after the fire, flood or other casualty, or such greater period as may be reasonably necessary, Landlord will commence to repair and restore the Premises
(including leasehold improvements) and any portion of the Project required for access to the Premises, and will diligently complete the same, but Landlord is not required (a) to expend more for such repair of the Premises and such Parking Area
than the net insurance proceeds (after any payment required under any Mortgage) reasonably allocable to the Premises and such Parking Area, or (b) to rebuild, repair or replace any of Tenant’s furniture, furnishings, fixtures, personal
property or equipment removable by Tenant under the provisions of this Lease or (c) to rebuild, repair or replace any property which Tenant has insured or is required to insure under the provisions of this Lease unless Tenant assigns or
delivers the insurance proceeds paid on account of such property to Landlord. 
 16.2 Casualty Loss During Last Year of
Lease. Notwithstanding the provisions of Paragraph 16.1, if the Premises are damaged by fire, flood, or other casualty during the last twelve (12) months of the Term, and such damage will require more than thirty (30) days after the
date of the casualty to repair, either party may cancel this Lease as of the date of the fire, flood or other casualty by notice to the other party within thirty (30) days thereafter. 
  

 15 

 16.3 Abatement of Rent. Landlord will allow Tenant a fair diminution of Rent to the
extent the Premises are rendered unusable or inaccessible due to a fire, flood, or other casualty and are not used by Tenant and/or a substantial portion of Tenant’s parking allotment is not available to Tenant, but only to the extent Tenant is
not entitled to reimbursement under insurance policies carried by Tenant or required to be carried by Tenant hereunder. Notwithstanding the above, in the event the casualty is flooding of the Premises, then such rental abatement shall be provided to
Tenant regardless of any insurance reimbursement. Such abatement shall apply to undamaged portions of the Premises to the extent that Tenant cannot reasonably, and in fact does not, conduct business in undamaged portions of the Premises due to
damage to critical facilities (e.g., laboratory facilities, a server room, or HVAC equipment), disruption caused by Landlord’s repair and restoration of other portions of the Building, or lack of reasonable access to the Premises or parking.
Such abatement shall end on the earlier of (i) the date Landlord or Tenant substantially completes its restoration obligations under Paragraph 16.1, or (ii) the date Tenant resumes normal business operations in the Premises. Except as
expressly provided to the contrary in this Lease, this Lease will not terminate, and Tenant will not be entitled to damages or to any abatement of rent or other charges, as a result of a fire or other casualty, repair or restoration and Landlord and
Tenant hereby waive the provisions of California Civil Code Sections 1932(2) and 1933(4) which permit termination of a lease upon destruction of Premises, and any other present or future statute that may so permit. 
 17. CONDEMNATION. If all or substantially all of the Building, Premises or the Parking Area are taken for any public or quasi-public
use under any governmental law, ordinance or regulation or by right of eminent domain or is sold to the condemning authority in lieu of condemnation, then this Lease will terminate when physical possession is taken by the condemning authority. If a
lesser but material portion of the Building is thus taken or sold or if a material portion of such Parking Area is so taken or sold and reasonable substitute parking is not provided to Tenant, Landlord or Tenant may terminate this Lease by notice to
the other party within sixty (60) days after the taking or sale, in which event this Lease will terminate when physical possession of the applicable portion of the Building or the Premises is taken by the condemning authority. If this Lease is
not terminated, rent payable will be reduced by the amount allocable to any portion of the Premises so taken or sold, Tenant’s share shall be appropriately adjusted, and Landlord, at its sole expense, will diligently restore the affected
portion of the Building, the Premises, or such Parking Area to substantially its former condition as far as commercially feasible. However, Landlord need not spend more for such restoration of the Premises and such Parking Areas than the
Premises’ allocable share of the net compensation or damages received by Landlord for the part of the Project taken. Landlord shall be entitled to receive all of the compensation awarded upon a taking of any part or all of the Premises or such
Parking Areas, including any award for any unexpired term of this Lease; provided, however, that Tenant shall be entitled to its portion of the award, as set forth in the following sentence. Tenant may seek an award in separate proceedings for its
personal property, trade fixtures, moving expenses, and the unamortized cost of Alterations paid for by Tenant. 
 In the event
of such taking or sale of the Premises or any part thereof for temporary use of not more than six (6) months, this Lease shall remain unaffected and rent shall not abate, and Tenant shall be entitled to such portion or portions of any award
made for such use with respect to the period of the taking which is within the Lease Term, provided that, if such taking shall remain in force at the expiration or earlier termination of this Lease, Tenant shall then pay to

  

 16 

 
Landlord a sum equal to the reasonable cost of performing Tenant’s obligations with respect to surrender of the Premises. 
 To the extent that it is inconsistent with the provisions of this Paragraph 17, each party hereto hereby waives the provisions of
Section 1265.130 of the California Code of Civil Procedure allowing either party to petition a court to terminate this Lease in the event of a partial taking of the Premises. 
 18. DEFAULTS AND REMEDIES 
 18.1 Events of Default. The occurrence of one or more of the following events shall constitute an Event of Default hereunder by Tenant: 
 18.1.1 Tenant fails to make a payment as and when due hereunder and such failure continues for more than five
(5) days after written notice of delinquency from Landlord; or 
 18.1.2 Tenant fails to deliver any
subordination agreement or any estoppel certificate under Paragraphs 20 or 21 of this Lease within the applicable time period provided therein, and such failure continues for five (5) Business days after Landlord’s second written notice to
Tenant that such instruments have not been delivered in a timely manner. Landlord agrees that such second notice shall conspicuously state that Tenant’s failure to timely respond to the materials contained therein within five business days
shall constitute an Event of Default under this Lease; or 
 18.1.3 Tenant fails to comply with any other
obligation under this Lease and does not cure such failure as soon as reasonably practicable and in any event within twenty (20) days after written notice or, if such failure is not susceptible of cure within twenty (20) days, as soon as
reasonably practicable after such written notice, provided Tenant commences to cure within such twenty (20) day period and diligently prosecutes such cure to completion; or 
 18.1.4 Tenant attempts any Transfer (as defined in Paragraph 19) except as expressly permitted pursuant to Paragraph
19; or 
 18.1.5 To the extent permitted by law, in the event Tenant or any Guarantor becomes insolvent,
makes a transfer in fraud of creditors or an assignment for the benefit of creditors, admits in writing its inability to pay its debts as they become due, or files a petition under any Section or Chapter of the United States Bankruptcy Code or any
similar law or statute; or an order for relief is entered with respect to Tenant or any Guarantor in any bankruptcy, reorganization or insolvency proceedings; or a pleading seeking such an order is not discharged or denied within sixty
(60) days after its filing; or the taking of any action at the corporate or partnership level by Tenant to authorize any of the foregoing actions on behalf of Tenant; or a receiver or trustee is appointed for all or substantially all assets of
Tenant or any guarantor or of the Premises or any of Tenant’s property located thereon in any proceedings brought by Tenant or Guarantor, or any receiver or trustee is appointed in any proceeding brought against Tenant or Guarantor and not
discharged within sixty (60) days after appointment or Tenant or Guarantor does not contest such appointment; or any part of Tenant’s estate under this Lease is taken by process of law in any action against Tenant (but in the event that
any

  

 17 

 
provision of this Paragraph 18.1.4 is contrary to any applicable law, such provision shall be of no force or effect). 
 To the extent permitted by Laws, any notice specified above shall serve as, and not be in addition to, any notice required under California
Code of Civil Procedure Section 1161 or otherwise regarding unlawful detainer actions. 
 18.2 Remedies. On an Event
of Default, Landlord may terminate this Lease by notice to Tenant, or continue this Lease in full force and effect, and/or perform Tenant’s obligations on Tenant’s behalf and at Tenant’s expense. 
 18.2.1 If and when this Lease is so terminated, all rights of Tenant and those claiming under it will terminate and
Tenant will immediately surrender the Premises to Landlord. In such event, Landlord may immediately recover from Tenant: 
 (a) The worth at the time of award of any unpaid rent which had been earned at the time of such termination; plus 
 (b) The worth at the time of award of the amount by which the unpaid rent which would have been earned after
termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 
 (c) The worth at the time of award of the amount by which the unpaid rent for the balance of the term after the time of award exceeds the amount of such rental loss that Tenant proves could be
reasonably avoided; plus 
 (d) Any other amount necessary to compensate Landlord for all the detriment
proximately caused by Tenant’s failure to perform Tenant’s obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, including but not limited to the unamortized principal balance of Tenant
Allowance, Broker’s commission, legal and other professional fees and other costs incurred by Landlord in connection with the entering into of this Lease, using an amortization schedule equal to the initial term of this Lease, plus
(A) expenses for cleaning, repairing or restoring the Premises; (B) expenses for altering, remodeling or otherwise improving the Premises for the purpose of reletting, including installation of leasehold improvements; (C) real estate
broker’s fees (to the extent applicable to the Lease Term), advertising costs and other expenses of reletting the Premises; (D) costs of carrying the Premises such as taxes and insurance premiums thereon, utilities and security precautions
to the extent not recovered as part of rental damages; (E) expenses in retaking possession of the Premises; and (F) attorneys’ fees and court costs permitted under Paragraph 24 below; plus 
 (e) Any other amounts in addition to or in lieu thereof that may be permitted by law; plus 
 (f) The entire unamortized amount of any Tenant Improvement Loan. 
 As used in Subsections (a) and (b) above, the “worth at the time of award” is computed by allowing interest at the Prime
Rate, plus four percent (4%) per annum (or at the maximum

  

 18 

 
rate permitted by law, whichever is less). As used in Subsection (c) above, the “worth at the time of award” is computed by discounting such amount at the discount rate of the
Federal Reserve Bank of San Francisco at the time of award plus one percent (1%). Landlord’s failure to relet the Premises shall not constitute a failure to mitigate damages. 
 18.2.2 Landlord shall have the remedy described in California Civil Code Section 1951.4 (Landlord may continue
this Lease in effect after Tenant’s breach, and abandonment of the Premises, and recover rent as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations). 
 18.2.3 Upon an Event of Default or when Tenant is no longer entitled to possession, subject to applicable laws,
Landlord may enter the Premises and dispose of Tenant’s property as herein provided, and may perform Tenant’s obligations hereunder on Tenant’s behalf. Tenant will reimburse Landlord on demand for Landlord’s reasonable
attorneys’ fees and other reasonable expenses in doing so. This Paragraph 18.2.3 shall survive expiration or termination of this Lease. 
 18.3 Continuing Liability. Subject to applicable laws, no repossession, reentering or reletting of the Premises or any part thereof by Landlord shall relieve Tenant or any Guarantor of its
liabilities and obligations under this Lease. 
 18.4 Remedies Cumulative. All rights and remedies of Landlord under this
Lease will be non-exclusive of and in addition to any other remedies available to Landlord at law or in equity, provided that except as provided in Paragraph 23.2, in no event shall Tenant be liable for any consequential damages suffered by
Landlord. In addition, Tenant’s employees, officers, directors, shareholders, and agents shall not have any personal liability for a breach of this Lease by Tenant. 
 18.5 No Waiver. Landlord’s or Tenant’s failure to insist on strict compliance with any terms hereof or to exercise any right or remedy, does not waive the same. Waiver of any agreement
regarding any breach does not affect any subsequent or other breach, unless so stated. A receipt by Landlord of any rent with knowledge of the breach of any covenant or agreement contained in this Lease shall not be a waiver of the breach, and no
waiver by Landlord or Tenant of any violation or provision of this Lease shall be effective unless expressed in writing and signed by the waiving party. Payment by Tenant or receipt by Landlord of a lesser amount than due under this Lease may be
applied to such of Tenant’s obligations as Landlord elects. No endorsement or statement on any check, and no accompanying letter, shall make the same an accord and satisfaction, and Landlord or Tenant may accept any check or payment without
prejudice to such party’s right to recover the balance of the amount due or pursue any other remedy provided in this Lease. 
 18.6 Landlord Default. Except as expressly provided in Paragraph 25.19 below or as otherwise provided in this Lease, Tenant waives any right to terminate this Lease and to vacate the Premises on Landlord’s default under this
Lease. In all other events, Tenant’s sole remedy on Landlord’s default is an action for damages or injunctive or declaratory relief. 
  

 19 

 19. ENCUMBRANCES, ASSIGNMENT AND SUBLETTING. Except upon Landlord’s written
consent, which shall not be unreasonably withheld or delayed, or as otherwise permitted herein, Tenant may not voluntarily, involuntarily or by operation of law, assign, transfer, or encumber this Lease or any estate or interest herein, or permit
the same to occur, or sublet or grant any right of occupancy for any part of the Premises, or permit such occupancy by any other parties other than Tenant and Tenant’s employees, agents, and contractors, or modify or terminate any agreement
providing for any of the foregoing (the foregoing collectively referred to as “Transfer,” and the other party thereto the “Transferee”). Except as provided in Paragraph 19.4 below, the following
transactions shall also be deemed Transfers: (a) if Tenant is a partnership or limited liability company the transfer, within a twelve-month (12-month) period, of fifty percent (50%) or more of the partnership or membership interests or
the dissolution of the partnership or limited liability company without its immediate reconstitution or (b) if Tenant is a corporation the sale or other transfer, within a twelve-month (12-month) period, of more than an aggregate of fifty
percent (50%) of the voting shares of Tenant or the dissolution, merger, consolidation, or other reorganization of Tenant. With any request for Landlord’s consent to any Transfer, Tenant shall remit to Landlord a transfer review fee of
$1,000. Any prohibited Transfer is voidable by Landlord. 
 19.1 Conditions of Transfer. Landlord’s consent
to a Transfer may, without limitation, be reasonably withheld on Landlord’s reasonable determination that (a) the Transferee’s business is not consistent with the character of the Project and its occupants, or is not consistent with
any exclusives or other rights held by other occupants of the Project, (b) the Transferee is either a government agency or an instrumentality of one; (c) Transferee’s intended use of the Premises is inconsistent with the permitted Use
or will materially and adversely affect Building systems; or (d) Landlord reasonably determines that the intended Transferee does not have the financial strength to perform its obligations under the applicable assignment or sublease. Consent by
Landlord to any Transfer shall not be a waiver of Landlord’s rights as to any subsequent Transfers. Any approved Transfer shall be expressly subject to the terms and conditions of this Lease. Upon an Event of Default while a Transfer is in
effect, Landlord may collect directly from the Transferee all sums becoming due to Tenant under the Transfer and apply this amount against any sums due Landlord by Tenant, and Tenant authorizes and directs any Transferee to make payments directly to
Landlord upon notice from Landlord. No direct collection by Landlord from any Transferee shall constitute a novation or release of Tenant or any Guarantor, a consent to the Transfer or a waiver of the covenant prohibiting Transfers. At any time an
Event of Default is occurring hereunder, Landlord, as Tenant’s agent, may endorse any check, draft or other instrument payable to Tenant for sums due under a Transfer, and apply the proceeds in accordance with this Lease; this agency is coupled
with an interest and is irrevocable. 
 19.2 Request to Assign or Sublet; Cancellation. Tenant shall provide Landlord
with not less than thirty (30) days prior notice of a proposed Transfer. With any request for consent to a Transfer, Tenant will submit a copy of the proposed Transfer document to Landlord and notify Landlord of the proposed effective date of
the Transfer, the name of the proposed Transferee (accompanied by evidence of the nature, character, ownership, business, and financial condition of the Transferee and its business), a general description of any proposed alterations (if known) and
all terms and conditions (including rental) of or relating to the Transfer. Notwithstanding anything to the contrary in this Paragraph 19, within thirty (30) days following

  

 20 

 
(i) any request for Landlord’s consent to an assignment or a sublease of more than 60% of the Premises for all or substantially all the remaining Lease Term, or (ii) at any time,
if Tenant enters into any Transfer without obtaining the consent of Landlord as required herein, Landlord, by notice to Tenant, may terminate this Lease (and, in the case of a sublease of less than all of the Premises, Landlord may terminate this
Lease as all of the portion of the Premises proposed to be sublet), as of the proposed effective date of the Transfer as if that were the original Expiration Date or immediately, if Tenant enters into the Transfer without obtaining the consent of
Landlord. If Landlord so elects to terminate, Landlord shall have the right to relet the Premises (or the portion of the Premises as to which this Lease is terminated pursuant to Landlord’s election as a result of a partial sublease) or any
portion thereof to anyone (including the proposed Transferee) on any terms, and Tenant shall not be entitled to any portion of any profit Landlord may realize as a result of any such reletting. If this Lease is terminated as to a portion of the
Premises as a result of the foregoing, then Base Rent, Tenant’s Share of Operating Expenses, Tenant’s parking rights, and any other provisions hereof based upon the rentable area of the Premises shall be reduced by the amount allocable to
such portion of the Premises so terminated. If Landlord does not terminate the Lease as provided herein, then Landlord shall grant or deny its consent to the proposed Transfer within thirty (30) days following submission of Tenant’s
request accompanied by the information required herein and the transfer review fee. 
 19.3 Excess Rent. If the
consideration Tenant receives for any Transfer (including key money and bonus money and any payment in excess of fair market value for services or assets provided or transferred in connection with the Transfer) exceeds the rent payable under this
Lease for the same period and portion of the Premises after first deducting Tenant’s actual and reasonable costs of tenant improvements installed in connection with such Transfer, brokerage commissions and attorney’s fees incurred in
association with such Transfer, all amortized over the term of the sublease, if applicable, then 50% of the excess shall be due and payable by Tenant to Landlord as Additional Rent under this Lease within ten (10) days after receipt by Tenant.
Upon reasonable advance notice, during ordinary business hours, Tenant shall allow Landlord to review and audit Tenant’s book and records for the purpose of verifying Tenant’s calculation of excess rent payable to Landlord. 
 19.4 Permitted Transfers. Notwithstanding the provisions herein, Landlord’s consent shall not be required in connection with
(A) Tenant’s offering of stock on a public stock exchange or any issuance of additional equity interests in Tenant for reasonable consideration; or (B) any sublease or assignment of all or a portion of the Premises to any person,
corporation or partnership which (i) controls, is controlled by or is under common control with Tenant, (ii) merges with or enters into any similar business combination with Tenant, (iii) acquires control of Tenant or control of all
or substantially all of the stock or assets of Tenant at the Premises, or (iv) results from any corporate reorganization (each such Transfer a “Permitted Transfer”, and each such Transferee a “Permitted
Transferee”), provided that such Transfer is not a subterfuge to avoid Tenant’s obligations under this Lease, and in the event of a transaction described in items (B)(ii), (iii) or (iv) above the Transferee has a
financial condition at least equivalent to the financial condition of Tenant as of the date of this Lease. For purposes of this Paragraph 19.4, “control” shall mean ownership of at least 50% of all classes of stock of a
corporation, all memberships in a limited liability company or all classes of partners in a partnership. Tenant shall notify Landlord of any such Transfer promptly after its consummation. Such Transfer shall not release the original Tenant from any
obligation or liability hereunder. The termination

  

 21 

 
provisions and the rent sharing provisions of Paragraphs 19.2 and 19.3 shall not apply to a Permitted Transfer. 
 20. SUBORDINATION. Landlord represents and warrants to Tenant that as of the Commencement Date, there is no Mortgage or ground lease covering any part of the Building or the Project. This Lease and
all rights of Tenant under this Lease are subordinate to any of the following, and any modifications thereof, which may hereafter affect any portion of the Building: any Mortgage, or any ground or underlying lease covering any part of the Building,
provided that the Mortgage holder or ground lessor shall agree in a commercially reasonable form acceptable to Tenant, that Tenant’s peaceable possession of the Premises will not be disturbed on account of such subordination so long as
Tenant is not in default, after notice and expiration of applicable cure periods and performs all obligations hereunder. Subject to the provisions of this Paragraph 20, on sale by foreclosure of a Mortgage or sale in lieu of foreclosure, Tenant will
attorn to the purchaser if requested by such purchaser, and recognize the purchaser as the Landlord under this Lease. Within ten (10) Business days after demand from time to time, Tenant shall execute, acknowledge and deliver to Landlord any
commercially reasonable instruments necessary or proper to evidence such subordination and/or attornment or, if Landlord so elects, to render any of the foregoing subordinate to this Lease or to any or all rights of Tenant hereunder. Subject to the
provisions of this Paragraph 20, Tenant further waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the
obligations of Tenant hereunder in the event of any such foreclosure proceeding or sale, and agrees that this Lease shall not be affected in any way whatsoever by any such proceeding or sale unless the Mortgagee, or the purchaser, shall declare
otherwise. 
 21. ESTOPPEL CERTIFICATE. Upon Landlord’s written request from time to time, Tenant will execute and
deliver to Landlord, within ten (10) days after Tenant’s receipt of Landlord’s written request, certificates, an example of which is attached hereto as Exhibit E, certifying: (i) the date of commencement of this Lease;
(ii) the fact that this Lease is unmodified (except as the certificate specifies) and in full force and effect; (iii) the date to which the sums payable under this Lease have been paid; (iv) that to Tenant’s actual knowledge,
there are no current material defaults under this Lease by either Landlord or Tenant except as specified; and (v) such other factual matters as Landlord reasonably requests. This certification may be relied upon by any actual or prospective
Mortgagee or purchaser of all or part of the Building or any interest therein or in Landlord. Failure to so execute and deliver said certificate will be conclusive upon Tenant (i) that this Lease is in full force and effect, without
modification except as may be represented by Landlord, (ii) that there are no uncured defaults in Landlord’s performance, and (iii) that no more than one (1) month’s rental has been paid in advance; and Tenant irrevocably
authorizes Landlord, as Tenant’s attorney-in-fact and in Tenant’s name, to so execute and deliver said certificate. 
 22. SIGNS. Tenant shall be permitted to maintain its signage in place as of the Commencement Date. Landlord and Tenant shall use commercially reasonable efforts to obtain appropriate governmental approval for Tenant to install
additional signage visible to Highway 101. The costs of fabricating and installing such freeway signage shall be at Tenant’s expense. During the first six months of the Lease Term, Landlord shall, at its expense, install directional signage
approved by Tenant in the Common Areas to direct Tenant’s employees and guests to its

  

 22 

 
main entrance. Landlord shall obtain Tenant’s prior written approval of such directional signage, which consent shall not be unreasonably withheld, conditioned or delayed. Except as provided
above, Tenant shall not place, maintain, or permit on any exterior door, wall, or window of the Premises, or the Building, any other sign, awning, canopy, marquee, or other advertising without the prior written consent of Landlord in Landlord’s
reasonable discretion. If Landlord consents to any sign, awning, canopy, marquee, decoration, or advertising matter, Tenant shall maintain it in good appearance and repair at all times during this Lease. If at the end of the Term, any of the items
mentioned in this Paragraph are not removed from the Premises by Tenant, that item may, without damage or liability, be removed and disposed of by Landlord at Tenant’s reasonable expense. 
 23. SURRENDER OF PREMISES. As soon as its right to possession ends, Tenant will surrender the Premises to Landlord in good condition
and with the HVAC equipment maintained and serviced as provided in the Lease and all floors and carpets in good repair and condition, except for reasonable wear and tear, and for damage or destruction by fire, flood or other casualty. Tenant will
concurrently deliver to Landlord all keys to the Premises. If possession is not immediately surrendered by Tenant, the provisions of Paragraph 23.2 below shall apply. 
 23.1 Leasehold Improvements and Fixtures. At the expiration or termination of the Term, Landlord may require the removal of any or all personal property and equipment from the Premises (including
without limitation all cable trays and racks), and the restoration of the Premises to its condition as of the Commencement Date (together with the Tenant Improvements installed pursuant to Exhibit C), except for reasonable wear and tear, at
Tenant’s expense. Further and within ten (10) days following written request thereof by Landlord, Tenant, at its expense, in compliance with the National Electric Code or other applicable law, shall remove all communications, fiber, phone
and data cabling and related telecom equipment that is installed by or for Tenant. All other Alterations made to the Premises shall remain upon and be surrendered with the Premises at the expiration or termination of the Term. All removals by Tenant
will be accomplished in a good and workmanlike manner so as not to damage any portion of the Premises or Building, and Tenant will promptly repair and restore all damage done. If Tenant does not so remove any property which it has the right or duty
to remove, and such failure continues for more than ten (10) days after written notice from Landlord, Landlord may immediately either claim it as abandoned property, or remove, store and dispose of it in any manner Landlord may choose, at
Tenant’s cost and without liability to Tenant or any other party. 
 23.2 Holding Over. If Tenant does not surrender
the Premises as required and holds over after its right to possession ends, Tenant shall become a tenant at sufferance only, at a monthly rental rate equal to one hundred fifty percent (150%) of the Base Rent payable in the last prior full
month, or the then existing fair market rental, whichever is greater, plus 100% of Additional Rent, without renewal, extension or expansion rights, and otherwise subject to the terms, covenants and conditions herein specified, so far as applicable.
Nothing other than a fully executed written agreement of the parties creates any other relationship. Tenant is liable for Landlord’s loss, costs and damage from such holding over, including, without limitation, those from Landlord’s delay
in delivering possession to other parties. These provisions are in addition to other rights of Landlord hereunder and as provided by law. 
  

 23 

 24. PROFESSIONAL FEES. Either party shall be entitled to reasonable attorneys’
fees and all other costs and expenses incurred in the preparation and service of legitimate notices of default and consultations in connection therewith, whether or not a legal action is subsequently commenced in connection with such default. In any
dispute between the parties (whether or not litigated) arising hereunder or out of Tenant’s use or occupancy of the Premises, the prevailing party’s reasonable costs and expenses (including reasonable fees of attorneys and experts) will be
paid or reimbursed by the unsuccessful party. 
 25. GENERAL PROVISIONS. 
 25.1 Mortgagee Protection. Subject to the express terms of any non-disturbance agreement, Tenant shall not exercise any right to
terminate until (a) it gives written notice to any Mortgagee whose name and address have been furnished to Tenant, and (b) the same time period as is afforded Landlord for remedying the act or omission giving rise to such suit has elapsed
following the giving of the notice, without the same being remedied. During that time, subject to Paragraph 12, Landlord and/or any Mortgagee and/or their employees, agents or contractors may enter the Premises and do therein whatever may be
necessary to remedy the act or omission. 
 25.2 Transfer of Landlord’s Interest. Landlord may transfer, assign or
convey any or all of its interest in the Building or its rights under this Lease. Upon transfer of its rights under this Lease, Landlord is freed and relieved of all then future obligations under this Lease, provided that the transferee shall
have assumed in writing those obligations, and Tenant will look solely to the successor to Landlord for such future obligations. This Lease shall inure to the benefit of and bind all parties hereto and their respective successors and assigns.

 25.3 Waiver. Tenant waives any right it may now or hereafter have (i) to redeem the Premises or to have a
continuance of this Lease after termination of the Lease, Tenant’s right of occupancy or the Term, (ii) for exemption of property from liability for debt or for distress for rent, or (iii) relating to delay in levy of execution in
case of eviction for nonpayment of rent. 
 25.4 Identification of Tenant. If there is more than one party constituting
Tenant or any Guarantor, their obligations are joint and several, and Landlord may proceed against any one or more of them before proceeding against the others, nor shall any party constituting Tenant or Guarantor be released for any reason
whatsoever, including, without limitation, any amendment of this Lease, any forbearance by Landlord or waiver of any of Landlord’s rights, the failure to give any party constituting Tenant or Guarantor any notices, or the release of any party
liable for the payment of Tenant’s obligations. If there is more than one party constituting Tenant, any of them acts for all others in every regard with respect to this Lease (including but not limited to any renewal, extension, expiration,
termination or modification). 
 25.5 Interpretation of Lease. Tenant acquires no rights by implication from this Lease,
and is not a beneficiary of any past, current or future agreements between Landlord and third parties. Surrender or cancellation of this Lease shall not work a merger, and shall, at Landlord’s option, assign to it all subleases or subtenancies.
The delivery of keys to Landlord or Landlord’s managing agent is not a termination of this Lease or a surrender of the Premises. Headings in this Lease are for convenience only, and do not affect the meaning of the text.

Unless context indicates otherwise, words of any gender or grammatical number include all genders and numbers. Where context conflicts with the definition of any term, context will control, but
only for that use and related uses. If any provision of this Lease or any application thereof is invalid, void or illegal, no other provision or application shall be affected. Time is of the essence of every provision of this Lease. California law
governs this Lease. The parties agree to submit to jurisdiction in the state or federal courts of the City and County of San Francisco, California for resolution of any litigation related to this Lease. Neither party may record this Lease or a copy
or memorandum thereof. Submission of this Lease to Tenant is not an offer, and Tenant will have no rights hereunder until each party executes a counterpart and delivers it to the other party. 
 25.6 Limitation on Liability. Landlord’s rights hereunder are solely for Landlord’s benefit, and Landlord has no duty to
exercise them for the benefit of Tenant or others. Any liability of Landlord to Tenant for a breach of this Lease, or arising from the relationship under it, is limited to twenty percent (20%) of the value of the Building, and Landlord and
Landlord’s employees, officers, directors, shareholders, partners and agents shall not be personally liable for any deficiency; but this does not limit or deny any remedies which involve personal liability, and nothing in this Paragraph 25.6
shall be deemed to limit the liability of Landlord’s insurance carriers. Tenant shall not, however, name Landlord’s employees, officers, directors, shareholders, partners and agents as a defendant in any action seeking to impose personal
liability on any one or more of them for a breach of this Lease. If Tenant proposes any action which requires Landlord’s consent and such consent is impermissibly withheld, denied or delayed, Tenant may seek an injunction or specific
performance and/or damages, but Tenant shall not have the right to terminate this Lease on account thereof. Landlord’s interest in the Building shall include, without limitation, all rental and other income, and all sales, insurance and
condemnation proceeds derived from the ownership and operation of the Building. 
 25.7 Financial Statements. Tenant
represents, warrants and covenants that financial statements heretofore or hereafter furnished to Landlord, in connection with this Lease, are accurate and are not materially misleading. At any time during the Term, but in no event more than once in
any calendar year (or at any time there is a continuing monetary Event of Default) and subject to the execution by Landlord of a Confidentiality Agreement reasonably acceptable to both Landlord and Tenant, Tenant shall, upon ten (10) days prior
written notice, provide Landlord with a current financial statement and financial statements of the two (2) years prior to the current financial statement year, and prepared in accordance with generally accepted accounting principles and, if
such is Tenant’s normal practice, audited by an independent certified public accountant. 
 25.8 Quiet Enjoyment. If
Tenant pays all sums and performs all its other obligations under this Lease, Tenant shall and may peaceably and quietly have, hold and enjoy the Premises, subject to this Lease and to rights to which the Lease is subordinate. Tenant acknowledges
that it may be subject to inconveniences typical of similar projects, such as construction, maintenance and repair in other areas of the Project and Building. 
 25.9 Payments and Notices. Any notice or document shall be considered received when personally received (or upon refusal to accept delivery) by mail, messenger, overnight courier or otherwise to
the parties hereto at the respective addresses set forth on the

  

 25 

 
signature page of this Lease, or at such other address as they may specify from time to time by written notice delivered in accordance with this Paragraph 25.9. All payments required to be made
by Tenant to Landlord are to be paid, without prior demand except as may be specified and, except as expressly specified, without any setoff, deduction or counterclaim whatsoever, in legal tender of the United States of America at the address set
forth on the invoice or, if no invoice is submitted or no address is set forth, at the address for the Landlord set forth on this Lease or at any other address as Landlord may specify from time to time by written notice in accordance with this
Paragraph 25.9. 
 25.10 Late Payments. If any amounts due hereunder from Tenant are not received by Landlord within five
(5) days after said amounts are due, Tenant shall also pay to Landlord a late charge of five percent (5%) of all such past due amounts for which the parties agree is a fair and reasonable estimate of the extra costs (including, without
limitation, processing and accounting charges) Landlord will incur by reason of the late payment. Acceptance of any late charge shall not constitute a waiver of Tenant’s default with respect to such overdue amount, or prevent Landlord from
exercising any of its other rights and remedies. Any amounts overdue from Tenant hereunder shall accrue interest from the date due at the Prime Rate plus four percent (4%) per annum. 
 25.11 Rules and Regulations. Tenant shall comply with the Rules and Regulations (as reasonably changed from time to time as therein
provided) attached hereto as Exhibit F. In the event of any conflict between the terms of the Rules and Regulations and the provisions of the text of this Lease, the provisions of this Lease shall control and prevail. 
 25.12 Rights Reserved by Landlord. In addition to other rights retained or reserved, subject to the other provisions of this Lease,
Landlord reserves the following rights, exercisable without notice (except as expressly provided) and without liability to Tenant and without effecting an eviction, constructive or actual, or in any way diminishing Tenant’s obligations:
(a) to install and maintain, modify or remove any signs on the exterior and interior of the Project other than Tenant’s signage as permitted herein; (b) to designate and reasonably approve, prior to installation, all types of interior
and exterior window treatments; (c) the exclusive right to designate, limit, restrict and control any business and any service in or to the Project or its tenants, except as permitted or required under this Lease; (d) to keep, and to use
in appropriate instances, keys to all doors within and into the Premises; (e) to decorate and make repairs, alterations or additions, whether structural or otherwise, in and about any part of the Project and to enter the Premises for these
purposes and, during such work, to temporarily close doors, entryways, public space in the Project, to interrupt or temporarily suspend services and facilities and to change the arrangement of public parts of Project other than the Premises;
(f) to approve the weight, size and location of safes and other heavy equipment and articles in and about the Premises and the Building (movement of Tenant’s property is entirely at the risk and responsibility of Tenant, and Landlord
reserves the right to require permits before allowing any property to be moved into or out of the Building); (g) to have access to any mail receptacles located on the Project according to the rules of the United States Postal Service;
(h) to close any part of the Common Areas to the extent necessary in Landlord’s opinion to prevent the accrual of any prescriptive rights, to temporarily close any part of the Common Areas to repair and maintain them or for any other
reasonable purpose, or to change the nature of the Common Areas, including without limitation changes in the location, size, shape, and number of

  

 26 

 
driveways, entrances, parking spaces, parking areas, loading and unloading areas, ingress, egress, direction of traffic, landscaped areas, and walkways provided Tenant’s parking rights are
not materially affected by any such changes; and (i) to take all reasonable measures Landlord considers advisable for the security of the Project and its occupants. In exercising its rights hereunder, Landlord shall use commercially reasonably
efforts to minimize any interference with Tenant’s use of and access to the Premises and to provide Tenant with its entire parking allotment. 
 25.13 Responsibility for Others. Where either party waives rights against the other party, to the extent permitted by law, it also waives the same rights against the other party’s employees,
officers, directors, shareholders, partners, agents, contractors and invitees. The waiver shall be considered a waiver on behalf of the party making it, and to the extent permitted by law, of all that party’s employees, officers, directors,
shareholders, partners and agents, and of anyone claiming under any of them, including insurers and creditors. Wherever in this Lease Tenant agrees not to do a particular thing, Tenant also agrees not to permit its employees, agents, contractors or
invitees to do so. 
 25.14 Landlord’s Costs. Where Tenant is required to pay or reimburse Landlord for the costs of
any item, the cost shall be the reasonable and customary charge established by Landlord from time to time, including a reasonable allocation of Landlord’s overhead, administrative and related costs associated with the ownership and operation of
the Building. Failure to pay any reimbursable cost shall be treated as a failure to pay rent. In connection with any request by Tenant for the consent of Landlord to an Alteration or other action proposed by Tenant under this Lease, Tenant shall pay
Landlord’s reasonable costs and expenses incurred in connection therewith, including attorneys’, architects’, engineers’ and other consultants’ fees. 
 25.15 Invoices. Tenant will promptly notify Landlord of any dispute it may have regarding Landlord’s invoices, provided however
that the foregoing sentence shall not limit Tenant’s right to audit Operating Expenses as provided in Paragraph 4.3 above. 
 25.16 Force Majeure. When a period of time is herein prescribed for action to be taken by a party, other than the payment of Rent or other funds, that party shall not be liable or responsible for, and there is excluded from the
computation for any such period of time, any delays due to strikes, riots, acts of God, shortages of labor or materials, war, governmental laws, regulations or restrictions or any other cause of any kind whatsoever which are beyond the control of
the party. Subject to the preceding sentence, time is of the essence of every part of this Lease. 
 25.17 Lender
Modification. Tenant agrees to make such reasonable modifications to this Lease as may reasonably be required in connection with the obtaining of normal financing or refinancing of the Building. 
 25.18 Negotiated Transaction. The parties mutually acknowledge that this Lease has been negotiated at arm’s length. The
provisions of this Lease shall be deemed to have been drafted by all of the parties and this Lease shall not be interpreted or constructed against any party solely by virtue of the fact that such party or its counsel was responsible for its
preparation. 
  

 27 

 25.19 Adverse Condition. If at any time during the Lease Term, Tenant is prevented
from using all or any portion of the Premises, or Tenant is able to conduct its operations in all or any portion of the Premises only at a significantly reduced level or under materially adverse conditions due to (i) the negligence or willful
misconduct of Landlord or any of Landlord’s employees, contractors or agents (“Landlord Parties”) which interrupts the utilities or services provided to or reasonable access to the Premises or (ii) the presence or
threatened presence of hazardous substances or other situations that pose a material health risk to occupants of the Premises, or (iii) any condition constituting a constructive eviction arising due to the act, omission or negligence of
Landlord or any Landlord Party (each, an “Abatement Event”), for a period of ten (10) consecutive days after written notice from Tenant (“Abatement Period”), Rent shall abate to the extent of such
interference commencing immediately following expiration of the Abatement Period and continuing for the time period and to the extent that Tenant’s use of the Premises is adversely affected. 
 Landlord shall use diligent efforts to restore Tenant’s use of the Premises as soon as practicable. If an Abatement Event continues for
ninety (90) consecutive days after Tenant has notified Landlord of the existence of such Abatement Event, Tenant shall thereafter have the ongoing right, until such Abatement Event is eliminated, to terminate this Lease as to all or any portion
of the Premises. Tenant’s termination of this Lease pursuant to this Paragraph 25.19 shall not constitute an election of remedies and shall not waive any claims Tenant may otherwise have against Landlord under this Lease or at law or in equity.
The provisions of this Paragraph shall not apply to a casualty or an eminent domain taking. 
 25.20 Access. Tenant shall
have access to the Premises 24 hours per day, seven days per week, subject to the provisions of this Lease. 
 THIS LEASE
CONTAINS ALL AGREEMENTS OF THE PARTIES CONCERNING THIS SUBJECT MATTER, SUPERSEDING ANY SUCH PRIOR AGREEMENTS, REPRESENTATIONS OR WARRANTIES, AND MAY BE AMENDED OR MODIFIED ONLY BY A WRITTEN AGREEMENT SIGNED BY BOTH PARTIES.

 ADDENDUM 
 TO LEASE 
 This Addendum is made and entered into by and between RNM
Lakeville, LLC, a Delaware limited liability company, as Landlord, and Calix Networks, Inc., a Delaware corporation, as Tenant, and is dated as of the date set forth on the first page of the Lease between Landlord and Tenant to which this Addendum
is attached (the “Lease”). The promises, covenants, agreements and declarations made and set forth herein are intended to and shall have the same force and effect as if set forth at length in the body of the Lease. To the
extent that the provisions of this Addendum are inconsistent with the terms and conditions of the Lease, the terms of this Addendum shall control. 
 26. TENANT’S EXTENSION OPTION. 
 26.1 Grant of Option. Tenant
shall have the right and option (the “Extension Option”) to extend the Term of this Lease for two (2) additional periods of five (5) years each (each an “Extension Term”), commencing
immediately upon expiration of the then expiring Lease term (the “Adjustment Date”), upon and subject to the terms, conditions and provisions below. 
 26.2 Exercise of Extension Option. To exercise an Extension Option, Tenant must deliver written notice of Tenant’s irrevocable
and unconditional exercise of the Extension Option to Landlord not earlier than fifteen (15) months and not later than twelve (12) months prior to the applicable Adjustment Date. If Landlord does not receive such notice from Tenant by that
time, then Tenant’s Extension Option and any subsequent Extension Option shall forever lapse unexercised and be of no further force or effect whatsoever. 
 26.3 Effect of Exercise of Extension Option. If Tenant timely exercises Tenant’s Extension Option as provided herein, the Lease Term shall (by delivery of Tenant’s notice of exercise to
Landlord and without further action by Landlord or Tenant) be extended for the applicable Extension Term, upon and subject to all of the terms, conditions and provisions set forth in this Lease, except as provided below, and except that: the Base
Rent for the applicable Extension Term shall equal Market Rate (determined as provided below) as of the applicable Adjustment Date; Tenant shall have one fewer option to extend or renew; and the provisions of Exhibit C shall not apply to any
Extension Term. In addition, during each Extension Term, Landlord shall provide to Tenant a refurbishment allowance in the amount of $5.00 per square foot within the Premises to reimburse Tenant for repainting and re-carpeting the Premises.

 26.4 Definition of Market Rate. As used in this Lease, the “Market Rate” shall be the net
effective fair market rental rate (taking into account free rent, if any) as of the applicable Adjustment Date, for comparable space in the Project, Petaluma and southern Sonoma County, all based on the best information available at the time of
determination of the Market Rate. The Market Rate shall be based on prevailing rentals then being charged to new and renewal tenants for space of equivalent quality, size and location as the Premises (or adjusting the rental rate as appropriate for
differences therein), taking into such account the size, nature and stature of the tenant, the length of the Extension Option period during which such rate will apply, and differences in terms and provisions of the applicable leases, such as
pass-throughs of

  

 ADDENDUM, PAGE 1 

 
operating expenses and taxes. The Market Rate shall also take into account any differences in leasing commissions or tenant improvements or improvement allowances and all other relevant terms and
conditions. 
 26.5 Determination of Market Rate. 
 26.5.1 Agreement on Market Rate. If Tenant timely exercises Tenant’s Extension Option, as provided in Paragraph
26.2, then, during the sixty (60) day period following Landlord’s receipt of Tenant’s notice of exercise of Tenant’s Extension Option, Landlord and Tenant shall endeavor in good faith to agree upon the Market Rate. 
 26.5.2 Appointment of Appraisers. If Landlord and Tenant are unable to agree upon the Market Rate prior to the
expiration of the sixty (60) day period referred to in Paragraph 26.5.1, then Landlord and Tenant shall each appoint, by written notice delivered to the other prior to five (5) days after the expiration of such sixty (60) day period,
a real estate broker or appraiser who has significant current experience appraising rental rates for commercial real property in the Petaluma area to participate in the determination of the Market Rate. If either Landlord or Tenant fails timely to
appoint a qualified appraiser as proved above, and such failure continues for fifteen (15) days after the party which has appointed an appraiser gives notice to the other party of such appointment and makes demand for the appointment of a
qualified appraiser by the other party, then the determination of Market Rate to be made hereunder shall be made solely by such sole appraiser as may have theretofore been appointed, and such determination of the Market Rate by such sole appraiser
shall be binding upon both Landlord and Tenant. Otherwise the two appraisers appointed by Landlord and Tenant shall appoint, within twenty (20) days after they have been appointed, a third appraiser who is similarly qualified. If the two
appraisers appointed by Landlord and Tenant cannot agree on the appointment of a third appraiser within the time period provided, either Landlord or Tenant may seek the appointment of the same by the presiding judge for the Superior Court in the
County of Sonoma, California. The appraisers shall work together and share information in their efforts to determine and agree upon the Market Rate. The Market Rate shall be determined as provided below. 
 26.5.3 Determination of Market Rate by Appraisers. Landlord and Tenant shall each state in writing what it contends to
be the Market Rate, including whatever support for such contention it wishes to have considered by the appraisers. The third appraiser shall arrange for simultaneous exchange of such written contentions and for presentation of such additional
evidence, rebuttals, or other matters as the parties may wish to present and the appraisers may elect to hear or otherwise receive. The role of the appraisers shall be to select from the two contended Market Rates submitted by the parties the one
which is closest to the actual Market Rate as determined by the appraisers. The appraisers shall have no power to adopt a compromise or “middle ground” between the contended Market Rates submitted by the parties or to adopt any Market Rate
other than the contended Market Rate submitted by the party which is closest to the appraisers’ determinations as to actual Market Rate. If the appraisers do not agree upon the actual Market Rate, then each appraiser shall determine which of
the two contended Market Rates submitted by the parties is closest to the actual Market Rate determined by such appraiser and the contended Market Rate so selected by at least two of the appraisers shall be the Market Rate. The Market Rate as so
determined by the appraisers as provided herein shall be binding upon both Landlord and Tenant as the Market Rate. 
  

 ADDENDUM, PAGE 2 

 26.5.4 Payments Pending Determination; Costs. Landlord and Tenant
will use all reasonable diligence to cause the appraisers to perform in good faith and in a timely manner in order to make the determination for the Market Rate on or before the applicable Adjustment Date. If the appraisers do not make such
determination prior to the applicable Adjustment Date, the Lease shall nevertheless continue in full force and effect until such determination is made, and, commencing as of the date of a demand by Landlord for such payment. Tenant shall pay Base
Rent during such period based on the amount asserted by Landlord to be the Market Rate. Upon the determination by the appraisers of the Market Rate, the excess, if any, of the amount paid to Landlord by Tenant as provided above over the Market Rate
as so determined hereunder applicable to the period from the Adjustment Date to the date on which the Market Rate was so determined shall be credited by Landlord against the Base Rent next due from Tenant hereunder. The payment by Tenant of Base
Rent based on the Market Rate as so determined shall commence on the first day of the month following the date of such determination, and, in addition to such monthly installment of Base Rent, Tenant shall pay to Landlord the deficiency, if any, in
the amount earlier paid by Tenant as Base Rent based on Landlord’s asserted Market Rate in relation to the amount ultimately determined hereunder as the Market Rate. Landlord and Tenant shall each advance one half of any fees and expenses of
the appraisers required to be paid prior to the appraisers’ decision, but the party submitting the position adopted as the Market Rate in accordance with the procedure set forth above shall be entitled to reimbursement from the other party of
all such fees and expenses advanced by the prevailing party and the non-prevailing party shall pay (or reimburse the prevailing party for) all such fees and expenses within 30 days after demand; the reasonable attorneys’ fees and expenses of
counsel for the respective parties shall be paid and borne by the party engaging such counsel. 
 26.6 Limitations on
Extension Option. Time is of the essence as to the exercise of Tenant’s Extension Options. If Landlord does not timely receive delivery of Tenant’s notice of exercise of Tenant’s Extension Option, the option shall expire, lapse
unexercised and be of no further force or effect whatsoever, and Tenant shall have no further option to extend. Any election to exercise any Extension Option shall be null and void at the option of Landlord (A) if any Event of Default exists
hereunder at the time of such notice or at the Adjustment Date, or (B) if the named Tenant hereunder has assigned the Lease (other than to a Permitted Transferee) or subleased more than 80% of the Premises for all or substantially all of the
then remaining Lease Term at either the time of exercise of the Extension Option or the Adjustment Date (it being the intent of the parties to this Lease that such Extension Option is personal to the original Tenant hereunder, and shall not be
assignable to or exercisable by or for the benefit of any assignee, sublessee or other transferee of the original Tenant hereunder other than to Permitted Transferees). Transfer of all or any portion of Tenant’s rights under this Paragraph 26
(other than to Permitted Transferees) is absolutely prohibited. 
 27. RIGHT OF FIRST OFFER. Subject to the terms and
conditions set forth below and to the superior rights of tenants of the Project as of the date of this Lease, Tenant shall have an ongoing right of first offer (the “Right of First Offer”) with respect to any space within the
1039 North McDowell Boulevard building (“Offer Space”). Landlord shall provide written notice to Tenant (“Advice”) at such time as Landlord determines to offer to lease any or all of the Offer Space or
receives an offer from a third party to lease any Offer Space. The Advice shall state the location and approximate square footage of the Offer Space, and the proposed commencement date of lease of the Offer Space. Tenant may elect to lease all such
Offer Space, under the terms

  

 ADDENDUM, PAGE 3 

 
and provisions of this Lease as modified below, by providing Landlord with written notice of exercise (the “Notice of Exercise”) within ten (10) Business days after
the date of the Advice. If Tenant fails to exercise its Right of First Offer as to any Offer Space, then Tenant’s Right of First Offer with respect to such Offer Space shall lapse and be of no further force and effect until the earlier of six
months following the date of the Advice respecting such Offer Space or if such Offer Space is leased during said six-month period, then at such time as such Offer Space is subsequently vacated. This Right of First Offer is personal to the Tenant
named herein and Permitted Transferees and may not be assigned or transferred (other than to Permitted Transferees). Tenant must elect to lease all of the space subject to an Advice and may not elect to lease only a portion thereof. 
 27.1 Notwithstanding the above, Tenant shall have no Right of First Offer, and Landlord need not provide Tenant with an Advice, if

 (a) Tenant is in default under the Lease beyond any applicable cure periods at the time that Landlord would
otherwise deliver the Advice; or 
 (b) Tenant has assigned this Lease (other than to Permitted Transferees) or
subleased all or more than 80% of the Premises for all or substantially all the then remaining Lease Term on the date that Landlord would deliver the Advice: or 
 (c) The current tenant of the Offer Space is extending or otherwise remaining in the Offer Space beyond the term of its
original lease pursuant to an extension option or otherwise. 
 27.2 Lease Terms After Exercise. If Landlord timely
receives Tenant’s Notice of Exercise, then, commencing on the commencement date stated in the Advice, such Offer Space shall be considered a part of the Premises on the terms set forth in this Lease. Base Rent for the Offer Space shall be
calculated at the rate then in effect for the original Premises. For example, if the commencement date for the Offer Space is the first day of the twenty-fifth month of the Lease Term, then Base Rent on the Offer Space shall be calculated at a rate
of $1.35 per square foot per month and shall thereafter increase when the rental rate increases for the original Premises. The Tenant Allowance for the Offer Space shall be prorated to reflect the shorter lease term for the Offer Space. For example,
if the commencement date for the Offer Space is the first day of the twenty-fifth month of the Lease Term, the Tenant Allowance for such space would be equal to $9.00 per square foot ($15.00 x 36/60). If Landlord is delayed delivering possession of
such Offer Space due to the holdover or unlawful possession of such space by any party, Landlord shall use reasonable efforts to obtain possession of the space, and the commencement of the term for such Offer Space shall be postponed until the date
Landlord delivers possession of such Offer Space to Tenant free from occupancy by any party. If Landlord fails to deliver the Offer Space within 180 days after the scheduled commencement date, Tenant shall thereafter have the right to terminate its
lease of the applicable Offer Space until possession thereof is tendered to Tenant. 
 28. PARKING. Tenant shall be
entitled to the non-exclusive use of up to 3.2 unreserved and unassigned parking spaces per 1,000 square feet in the Premises in accordance with Landlord’s rules and regulations as may be reasonably amended from time to time. Tenant shall not
park any vehicle other than ordinary passenger vehicles, passenger vans, and small

 29.2 Tenant’s Indemnity. Tenant shall be liable to Landlord for and
indemnify and hold Landlord harmless against all damages (including investigation and remedial costs), liabilities, losses (including diminution of value of the Premises), fines, penalties, fees, and claims, demands, orders or enforcement actions
arising out of activities associated with Hazardous Materials which activities are conducted or permitted by Tenant within the Premises during the Lease Term or any other period during which Tenant, its agents, contractors, employees, sublessees,
assignees or licensees are occupying the Premises or are conducted or permitted by Tenant, Tenant, its agents, contractors, employees, sublessees, assignees or licensees (“Tenant Parties”) at the Project. In the event Tenant
and/or Tenant’s Parties’ activities are responsible for a Hazardous Materials condition at the Project, Tenant shall promptly commence investigation and remedial activities to remediate such condition as required by applicable laws. Any
such remediation activities shall be deemed an Alteration requiring Landlord’s consent hereunder. If appropriate or required by law, these activities shall be conducted in conjunction with Federal, state and local oversight and approvals. If
any action of any kind is required or requested to be taken by any governmental authority to clean-up, remove remediate or monitor any Hazardous Materials (the presence of which is the result of the acts or omissions of Tenant or its Agents) and
such action is not completed prior to the expiration or earlier termination of the Lease, Tenant shall be deemed to have impermissibly held over until such time as such required action is completed, and Landlord shall be entitled to all damages
directly or indirectly incurred in connection with such holding over, including, without limitation, damages occasioned by the inability to re-let the Premises or a reduction of the fair market and/or rental value of the Premises. 
 29.3 Assignment and Subletting. It shall not be unreasonable for Landlord to withhold its consent to any proposed assignment or
subletting if (i) the proposed assignee’s or subtenant’s anticipated use of the Premises involves the storage, generation, discharge, transport, use or disposal of any Hazardous Material in a greater intensity and scope than
Tenant’s then- existing use, or (ii) the proposed assignee or subtenant has been required by any prior landlord, lender or governmental authority to “clean-up” or remediate any Hazardous Material and has failed to do so, or
(iii) the proposed assignee or subtenant is subject to a criminal investigation or enforcement order or proceeding by any government authority in connection with the use, generation, discharge, transport, disposal or storage of any Hazardous
Material. 
 29.4 List of Hazardous Materials. In the event Tenant intends to use or store or uses or stores Hazardous
Materials in or about the Premises (other than office supplies and household cleaning products typically used in offices), then upon request of Landlord, Tenant shall provide Landlord with a list of such Hazardous Materials (and the quantities
thereof) which Tenant uses or stores (or intends to use or store) on the Premises and the following provisions shall apply: 
 (a) Prior to Tenant using, handling, transporting or storing any Hazardous Material at or about the Premises, Tenant shall submit to Landlord a Hazardous Materials Management Plan
(“HMMP”) for Landlord’s review and approval, which approval shall not be unreasonably withheld. The HMMP shall describe: (aa) the quantities of each material to be used, (bb) the purpose for which each material
is to be used, (cc) the method of storage of each material, (dd) the method of transporting each material to and from the Premises and within the Premises (ee) the methods Tenant will employ to monitor the use of the material

  

 ADDENDUM, PAGE 6 

 
and to detect any leaks or potential hazards, and (ff) any other information any department of any governmental entity (city, state or federal) requires prior to the issuance of any required
permit for the Premises or during Tenant’s occupancy of the Premises. Landlord may, but shall have no obligation to review and approve the foregoing information and HMMP, and such review and approval or failure to review and approve shall not
act as an estoppel or otherwise waive Landlord’s rights under this Lease or relieve Tenant of its obligations under this Lease. If Landlord determines in good faith by inspection of the Premises or review of the HMMP that the methods in use or
described by Tenant are not adequate in Landlord’s good faith judgment to prevent or eliminate the existence of environmental hazards, then Tenant shall not use, handle, transport, or store such Hazardous Materials at or about the Premises
unless and until such methods are approved by Landlord in good faith and added to an approved HMMP. Once approved by Landlord, Tenant shall strictly comply with the HMMP and shall not change its use, operations or procedures with respect to
Hazardous Materials without submitting an amended HMMP for Landlord’s review and approval as provided above. 
 (b) Tenant shall pay to Landlord when Tenant submits an HMMP (or amended HMMP) the amount reasonably determined by Landlord to cover all Landlord’s costs and expenses reasonably incurred in connection with Landlord’s review
of the HMMP which costs and expenses shall include, among other things, all reasonable out-of-pocket fees of attorneys, architects, or other consultants incurred by Landlord in connection with Landlord’s review of the HMMP. Landlord shall have
no obligation to consider a request for consent to a proposed HMMP unless and until Tenant has paid all such costs and expenses to Landlord irrespective of whether Landlord consent to such proposed HMMP. Tenant shall pay to Landlord on demand the
excess, if any, of such costs and expenses actually incurred by Landlord over the amount of such costs and expenses actually paid by Tenant over the amount such costs and expenses actually incurred by Landlord. Tenant shall immediately notify
Landlord or any inquiry, test, investigation, enforcement proceeding by or against Tenant or the Premises concerning any Hazardous Material. Any remediation plan prepared by or on behalf of Tenant must be submitted to Landlord prior to conducting
any work pursuant to such plan and prior to submittal to any applicable government authority and shall be subject to Landlord’s consent. Tenant acknowledges that Landlord, as the owner of the Property, at its election, shall have the sole right
to negotiate, defend, approve and appeal any action taken or order issued with regard to any Hazardous Material by any applicable governmental authority. Landlord shall have the right to appoint a consultant to conduct an investigation to determine
whether any Hazardous Material is being used, generated, discharged, transported to or from, stored or disposed of in, on, over, through, or about the Premises, in an appropriate and lawful manner and in compliance with the requirements of this
Lease. Tenant, at its expense, shall comply with all reasonable recommendations of the consultant required to conform Tenant’s use, storage or disposal of Hazardous Materials to the requirements of applicable Law or to fulfill the obligations
of Tenant hereunder. 
 29.5 Landlord Indemnity. Landlord shall be liable to Tenant for and indemnify and hold
Tenant harmless against all damages (including investigative and remedial costs), liabilities and claims arising out of Landlord’s or Landlord’s agents’ activities associated with Hazardous Materials, or arising out of any Hazardous
Materials existing on or under the Building or the Project as of the Commencement Date of the Existing Lease, including any costs and

storage shall be permitted only by the prior written consent of Landlord or Landlord’s designated agent, which consent may be revoked at any time. In the event that any unauthorized storage shall occur, the Landlord shall have the right,
without notice, in addition to such other rights and remedies that it may have, to remove the property and charge the cost to Tenant, which cost shall be payable by Tenant to Landlord within 30 days after demand by Landlord.

covenants, and restrictions of public record now or hereafter affecting the Premises and any amendment thereof, and to cause its employees, suppliers, shippers, customers and invitees to abide and conform, provided that such rules and restrictions
shall not increase Tenant’s costs or materially impair Tenant’s rights or materially increase Tenant’s obligations under this Lease. Landlord shall not be responsible to Tenant for the non-compliance with said rules and regulations by
other tenants or authorized users of the Project. Any failure by Tenant or its agents, employees or representatives to observe and comply with the rules and regulations established by Landlord with respect to the Common Areas, which failure
continues or persists after written notice by Landlord to Tenant of such failures, shall be a default by Tenant hereunder. 
 30.3 Subject to Tenant’s rights otherwise set forth in the Lease, Landlord shall have the right in Landlord’s reasonable discretion, from time to time: (i) to make changes to the Common Areas, including, without
limitation, changes in the location, size, shape and number of driveways entrances, parking spaces, parking areas, loading and unloading areas, ingress, egress, direction of traffic, landscaped areas and walkways; (ii) to close temporarily any

Lease, then Landlord may thereafter do so and restore the Common Areas to their original condition prior to the installation thereof, and Tenant shall, within thirty (30) days of demand, reimburse Landlord for all reasonable costs incurred by
Landlord in connection therewith. Any damage caused by the installation, maintenance or removal of the equipment shall be promptly repaired at the sole cost and expense of Tenant. 
 31.3 Tenant shall, at its sole cost and expense, maintain all fees, permits and government agency licenses necessary in connection
with the installation, maintenance and operation of Tenant’s equipment. Landlord shall reasonably cooperate with Tenant in connection with obtaining such permits and licenses; provided, however, that Landlord shall have no obligation for any

 31.5 Tenant agrees to indemnify,
defend and protect and hold harmless Landlord from and against any and all costs, claims or liabilities incurred by Landlord by reason of the equipment. Tenant acknowledges that the inability of Tenant to install or operate any of the equipment

engage the mutually agreed upon Space Planner to prepare, in consultation with Tenant, plans and specifications for the Tenant Improvements. Within ten (10) Business days after receiving any such plans and specifications, Tenant shall approve
such Space Planning Documents or shall provide comments. Landlord shall pay for the cost of the initial draft of the space planning documents. Any additional costs incurred in development of the plans and specifications for any Tenant Improvements
shall be included within the Cost of Improvements. Once approved by Landlord and Tenant, the plans and specifications shall be referred to herein as the Approved Plans. 
  

	3.	TENANT IMPROVEMENT CONSTRUCTION. 

 3.1 All Tenant Improvements to be constructed or installed in the Premises shall be performed by Devcon Incorporated (“Devcon”) and in accordance with the Approved Plans (subject to such changes as may be
required by any governmental agency). The fee payable to Devcon shall not exceed 3% of “hard” construction costs (those items listed in Paragraph 1 (v) and (vi) under Cost of Improvements). Devcon shall cause all major trades to
be competitively bid to at least two qualified subcontractors reasonably designated by Landlord, provided Tenant shall approve the major subcontractors bidding on the work, which approval shall not be unreasonably withheld, conditioned or delayed.
Tenant shall have the right to reasonable verification of the Cost of Improvements. Existing improvements in the Premises, if any, may be used or incorporated in the Tenant Improvements on a strictly AS IS and with all faults basis and without
warranty of any kind, express or implied. Landlord shall not be required to commence work until the Approved Plans are filed with the governmental agencies having jurisdiction thereof and all required building permits have been obtained. Landlord
may cause the Approved Plans to be changed as may be required by any governmental agency, or as may be required due to structural or unanticipated field conditions. Landlord shall notify Tenant concerning any such changes promptly after Landlord
becomes aware that they are required, and shall obtain Tenant’s approval before authorizing any material changes. 
  

 EXHIBIT C, PAGE 2 

 3.2 Tenant hereby acknowledges that Landlord will be constructing the Tenant
Improvements during Tenant’s occupancy of the Premises, and Tenant hereby waives any claim of disturbance, interference or any claim for abatement of rent arising from Landlord performing such work. Landlord shall make all reasonable efforts to
minimize any disturbance to Tenant as a result of such work. 
 3.3 If Tenant desires any change in the Approved Plans or
any work in addition to the Tenant Improvements in accordance with the Approved Plans to be performed in the Premises (“Additional Tenant Work”), such proposed work shall be presented to Landlord for incorporation into the
Approved Plans, and associated costs shall be included within the Cost of Improvements. All plans and specifications for Additional Tenant Work shall be subject to review and approval by Landlord (which shall not be unreasonably delayed or withheld)
to insure, among other things, that the work is compatible with all other construction and all electrical and mechanical systems within the Building. Upon such written request and approval of same by Landlord, which shall be granted or withheld
within five (5) Business days from the date of receipt, Landlord shall submit to Tenant, for approval, a field order describing the change, a cost proposal and a Tenant Improvement Construction Schedule Adjustment. Tenant shall approve or
disapprove the change order, in writing, within five (5) Business days following receipt thereof. Landlord may refuse to make any changes (and proceed with the work in accordance with the Approved Plans) until Tenant so approves in writing the
description of the change, the cost proposal and a Tenant Improvement Construction Schedule Adjustment. If Tenant does not approve the change order, then Landlord may elect to withdraw the change request on Tenant’s behalf. 
 3.4 So long as no Event of Default has occurred and is continuing under the Lease, Landlord shall contribute the Tenant Allowance
towards the Cost of Improvements. If an Event of Default shall exist on the date disbursements of the Tenant Allowance or Tenant Improvement Loan are otherwise payable, and without limiting Landlord’s rights and remedies under Paragraph 18 of
the Lease, Landlord shall be entitled to withhold payment thereof until such Event of Default is cured. The Tenant Allowance shall be applied only for designing and building improvements to the Premises, including architectural and engineering fees,
construction of interior improvements, finishes, upgrades to the security system, power and HVAC systems, construction of exterior improvements for a new main entrance for the Premises, permit fees and the Construction Fee, and not for furniture
costs or any other cost or expense. If the Cost of Improvements and related fees and costs exceeds the Tenant Allowance and the amount of the Tenant Improvement Loan requested by Tenant, then Tenant shall reimburse Landlord for such excess within
ten (10) Business days after demand. If Landlord completes the Tenant Improvements without spending the entire Tenant Allowance and Tenant Improvement Loan, Tenant may use any remaining Tenant Allowance and Tenant Improvement Loan within the
first twenty-four (24) months of the Lease Term. If Tenant does not use the entire Tenant Allowance during that period, then all of such savings shall be for Landlord’s benefit, and Tenant shall have no right to any rebate, credit or
reimbursement for any portion of such savings. 
 3.5 So long as no Event of Default has occurred and is continuing under
the Lease, Landlord shall advance to Tenant, at Tenant’s option, the Tenant Improvement Loan to cover the Cost of Improvements and the Construction Fee in excess of the Tenant Allowance. Any and all

  

 EXHIBIT C, PAGE 3 

 
amounts advanced to Tenant by Landlord as a Tenant Improvement Loan shall accrue interest at a rate of nine percent (9%) per annum from the date of the advance and shall be amortized in
equal payments (“Tenant Improvement Loan Repayments”), calculated as of the first day of the calendar month in which the Tenant Improvement Loan is advanced through the end of the initial Lease Term. Tenant shall remit Tenant
Improvement Loan Repayments together with monthly Base Rent for the remainder of the initial Lease Term. Any and all repayments shall be applied first to unpaid interest and thereafter to principal. If this Lease is terminated for any reason prior
to the expiration of the initial Term, then the remaining balance shall be payable in full on the last day of the Term. 
 3.6 The Tenant Allowance and Tenant Improvement Loan shall only be available with respect to any Tenant Improvements constructed by Landlord or Tenant prior to February 15, 2011, subject to force majeure and Landlord delays in
completion of construction. 
 3.7 Landlord shall cause the Tenant Improvements to be constructed in a good and
workmanlike manner, free of defects and in compliance with all laws. 
 4. GENERAL. 
 4.1 All drawings, space plans, plans and specifications for any improvements or installations in the Premises are expressly subject
to Landlord’s prior written approval, which shall not be unreasonably withheld, conditional or delayed. Any approval by Landlord or Landlord’s architects or engineers of any drawings, plans or specifications prepared on behalf of Tenant
shall not in any way bind Landlord or constitute a representation or warranty by Landlord as to the adequacy or sufficiency of such drawings, plans or specifications, or the improvement to which they relate, but such approval shall merely evidence
the consent of Landlord to Tenant’s drawings, plans or specifications. 
 4.2 Any failure by Tenant to pay any
amounts due hereunder shall have the same effect under the Lease as a failure to pay rent. Any such failure, or failure by Landlord or Tenant to perform any of its other obligations hereunder, after notice and expiration of applicable cure periods,
shall constitute an event of default under the Lease, entitling the other party to all of its remedies under the Lease, at law and in equity.
