Subsidiaries, nor is the Company or any of its Subsidiaries bound by or a party to any options, licenses or agreements of any kind with respect to the patents, trademarks, service marks, trade names, copyrights, trade secrets, licenses, information,
proprietary rights and processes of any other person or entity, other than such licenses or agreements arising from the purchase of “off the shelf” or standard products. Except as set forth in the Disclosure Schedule, neither the Company
nor any of its Subsidiaries has received any communications alleging, nor is the Company aware of any basis for such allegation, that the Company or any of its Subsidiaries has violated or, by conducting its business as proposed, would violate any
of the patents, trademarks, service marks, trade names, copyrights or trade secrets or other proprietary rights of any other person or entity. The Company is not aware that any of the employees of the Company or any of its Subsidiaries are obligated
under any contract (including licenses, covenants or commitments of any nature) or other agreement, or subject to any judgment, decree or order of any court or administrative agency, that would interfere with the use of such employee’s best
efforts to promote the interests of the Company and its Subsidiaries that would conflict with the business of the Company and its Subsidiaries as proposed to be conducted. Neither the execution nor delivery of the Transaction Documents, nor the
carrying on of the Company’s or its Subsidiaries’ business by the employees of the Company or the Subsidiaries, nor the conduct of the Company or the Subsidiaries’ business as now conducted and as proposed to be conducted, will, to
the Company’s knowledge, conflict with or result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract, covenant or instrument under which any of such employees is now obligated. The Company does not
believe it is or will be necessary to use any inventions of any of the Company’s or its Subsidiaries’ employees (or persons they currently intend to hire) made prior to their employment by the Company or its Subsidiaries, except for
inventions, trade secrets or proprietary information that have been assigned to the Company or its Subsidiaries. The Company has taken reasonable measures to protect its material patents, trademarks, service marks, trade names, copyrights, trade

performance of the Company’s and each of its Subsidiaries’ contracts with its independent contractors, will not result in any such violation. Neither the Company nor any of its Subsidiaries has received any notice alleging that any such

Transaction Documents and the issuance and sale of the Shares pursuant hereto, will not, with or without the passage of time or giving of notice, result in any such violation, or be in conflict with or constitute a default under any such term, or
result in the creation of any mortgage, pledge, lien, encumbrance or charge upon any of the properties or assets of the Company or any of its Subsidiaries or the suspension, revocation, impairment, forfeiture or
non-renewal of any permit, license, authorization or approval applicable to the Company or any of its Subsidiaries, its business or operations or any of its assets or properties.

that the Purchasers have requested for deciding whether to acquire the Shares and all information that the Company believes is reasonably necessary to enable the Purchasers to make such a decision, including certain of the Company’s projections
describing its proposed business (collectively, the “Information”). To the Company’s knowledge, none of the representations or warranties of the Company contained in this Agreement, as modified by the Disclosure Schedule, or
any certificate furnished or to be furnished to the Purchasers at the Closing (when read together) contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained herein or

 3.31
Data Privacy. In connection with the Company’s collection, storage, transfer (including any transfer across national borders) and/or use of any personally identifiable information from any individuals, including any customers,

laws relating to data loss, theft and breach of security notification obligations. 

 3.32 Scope of Liability for the Company. Liability for the Company for any breach of
the representations and warranties that are qualified by “knowledge” contained in this ARTICLE 3 shall be limited to only those situations in which the Company has knowledge that the representation and warranty in question was false as of
the applicable Closing Date. All references to any “knowledge” of the Company and/or the Subsidiaries in this ARTICLE 3 shall mean to the knowledge of each of Bob Plaschke, Jim Walker, Jeff Pon, Joe Hooks, Peter Liu, Bengt Jonassen and
Chuck Becher and the knowledge that each of the foregoing would reasonably be expected to have obtained in the reasonable and diligent performance of their Company duties. 

3.33 No Directed Selling Efforts or General Solicitation. Neither the Company nor, to the Company’s Knowledge, any Person acting on
its behalf has conducted any general solicitation or general advertising (as those terms are used in Regulation D) in connection with the offer or sale of any of the Shares.

Person will have, as a result of the transactions contemplated by the Transaction Documents, any valid right, interest or claim against the Company or upon any other Purchaser for any commission, fee or other compensation pursuant to any agreement,

The Company shall pay, and hold the Purchasers harmless against, any liability, loss or expense (including, without limitation, reasonable attorney’s fees and out-of-pocket expenses) arising in connection with any such claim for fees pursuant to any such agreement, arrangement or understanding entered into by or on behalf of the
Company.     
 ARTICLE 4 

REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS 

Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants, as of the date of each Closing in which such Purchaser
purchases Shares, to the Company and to the Placement Agent as follows (unless as of a specific date therein): 
 4.1 Organization;
Authority. Such Purchaser is either an individual or an entity duly incorporated or formed, validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership,
limited liability company or similar power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of
the Transaction Documents and performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary corporate, partnership, limited liability company or similar action, as applicable,
on the part of such Purchaser. Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding
obligation of such Purchaser, enforceable against it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application
affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution
provisions may be limited by applicable law. 
 4.2 Purchaser Status. At the time such Purchaser was offered the Shares, it was, and
as of the date hereof it is, an “accredited investor” as defined in Rule 501 under the Securities Act. Such Purchaser is not a broker-dealer registered under Section 15 of the Exchange Act. Such Purchaser is acting alone in its
determination as to whether to invest in the Shares. Such Purchaser is not a party to any voting agreements or similar arrangements 

 with respect to the Shares. Except as expressly disclosed in a Schedule 13D or Schedule 13G (or amendments
thereto) filed by such Purchaser with the Commission with respect to the beneficial ownership of the Company’s Common Stock, such Purchaser is not a member of a partnership, limited partnership, syndicate, or other group for the purpose of
acquiring, holding, voting or disposing of the Shares. 
 4.3 Certain Transactions and Confidentiality. Other than consummating the
transactions contemplated hereunder, such Purchaser has not, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly executed any purchases or sales, including Short Sales, of the
securities of the Company during the period commencing as of the time that such Purchaser was first contacted by the Company, the Placement Agent or any other Person regarding the transactions contemplated hereby and ending immediately prior to the
date hereof. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct
knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager
that made the investment decision to purchase the Shares covered by this Agreement. Such Purchaser, its Affiliates and authorized representatives and advisors who are aware of the transactions contemplated by the Transaction Documents, maintained
the confidentiality of all disclosures made to it in connection with such transactions (including the existence and terms of such transactions). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a
representation or warranty, or preclude any actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future.    

 4.4 General Solicitation; Pre-Existing Relationship. Such Purchaser is not purchasing the
Shares as a result of any advertisement, article, notice or other communication regarding the Shares published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general
solicitation or general advertisement. Such Purchaser also represents that such Purchaser was contacted regarding the sale of the Shares by the Company or the Placement Agent (or an authorized agent or representative of the Company or the Placement
Agent) with which such Purchaser had a substantial pre-existing relationship. 
 4.5
Purchase Entirely for Own Account. The Shares to be received by such Purchaser hereunder will be acquired for such Purchaser’s own account, not as nominee or agent, and not with a view to the resale or distribution of any
part thereof in violation of the Securities Act, and such Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same in violation of the Securities Act without prejudice, however, to such
Purchaser’s right at all times to sell or otherwise dispose of all or any part of such Shares in compliance with applicable federal and state securities laws. Nothing contained herein shall be deemed a representation or warranty by such
Purchaser to hold the Shares for any period of time. 
 4.6 Experience of Such Purchaser. Such Purchaser, either alone or together
with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Shares, and has so evaluated the merits and
risks of such investment. Such Purchaser is able to bear the economic risk of an investment in the Shares and, at the present time, is able to afford a complete loss of such investment. 

4.7 Disclosure of Information. Such Purchaser has had an opportunity to receive all information related to the Company requested by it
and to ask questions of and receive answers from the Company and the Placement Agent regarding the Company, its business and the terms and conditions of the offering of the Shares. Neither such inquiries nor any other due diligence investigation
conducted by such Purchaser shall modify, limit or otherwise affect such Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement. 

4.8 Placement Agent. Such Purchaser hereby acknowledges and agrees that it has independently evaluated the merits of its decision to
purchase the Shares, and that (i) Placement Agent is acting solely as placement agent in connection with the execution, delivery and performance of the Transaction Documents and is not acting as an underwriter or in any other capacity and is
not and shall not be construed as a fiduciary for such Purchaser, the Company or any other Person in connection with the execution, delivery and performance of the Transaction Documents, and (ii) such Purchaser has not relied on the Placement
Agent or its officers, directors, employees, attorneys or Affiliates with respect to the negotiation, execution or performance of the Transaction Documents or any representation or warranty made in, in connection with, or as an inducement to the
Transaction Documents.     

 4.9 Interested Stockholders. Each Purchaser that is an “Interested
Stockholder” (as such term is defined in Section 203 of the General Corporation Law of the State of Delaware) represents and warrants that either (a) it has been an Interested Stockholder for at least three years prior to the date
hereof or (b) the transaction that resulted in such Purchaser becoming an Interested Stockholder was approved by the Board of Directors or a duly authorized committee thereof. 

4.10 Restricted Securities. Such Purchaser understands that the Shares are “restricted securities” and have not been
registered under the Securities Act and may not be offered, resold, pledged or otherwise transferred except (i) pursuant to an exemption from registration under the Securities Act or pursuant to an effective registration statement in compliance
with Section 5 under the Securities Act and (ii) in accordance with all applicable securities laws of the states of the United States and other jurisdictions. 

4.11 No Rule 506 Disqualifying Activities. Such Purchaser has not taken any of the actions set forth in, and is not subject to, the
disqualification provisions of Rule 506(d)(1) of the Securities Act. 
 4.12 Compliance. No part of the funds being used by such
Purchaser to acquire the Shares has been, or shall be, directly or indirectly derived from, or related to, any activity that may contravene United States federal or state or non-United States laws or
regulations. 
 4.13 Residency. Such Purchaser is a resident of or an entity organized under the jurisdiction specified below its
address on Exhibit A hereto. 
 4.14 ERISA. If such Purchaser is (1) an employee benefit plan subject to Title I of ERISA,
(2) a plan or account subject to Section 4975 of the Code or (3) an entity deemed to hold “plan assets” of any such plan or account, such Purchaser hereby represents and warrants, solely for purposes of assisting the
Placement Agent in relying on the exception from fiduciary status under U.S. Department of Labor Regulations set forth in Section 29 CFR 2510.3-21(c)(1), that a fiduciary acting on its behalf is causing
such Purchaser to enter into the Transaction Documents and the transactions contemplated hereby and thereby and that such fiduciary: 
 (a)
is an entity specified in Section 29 CFR 2510.3-21(c)(1)(i)(A)-(E); 
 (b) is independent (for
purposes of Section 29 CFR 2510.3-21(c)(1)) of each Placement Agent; 
 (c) is capable of
evaluating investment risks independently, both in general and with regard to particular transactions and investment strategies, including such Purchaser’s transactions under the Transaction Documents; 

(d) has been advised that, with respect to each Placement Agent, neither such Placement Agent nor any of its respective affiliates has
undertaken or will undertake to provide impartial investment advice, or has given or will give advice in a fiduciary capacity, in connection with such Purchaser’s transactions contemplated by the Transaction Documents; 

(e) is a “fiduciary” under Section 3(21)(a) of ERISA or Section 4975(e)(3) of the Code, or both, as applicable, with
respect to, and is responsible for exercising independent judgment in evaluating, such Purchaser’s transactions contemplated hereby; and 

(f) understands and acknowledges that no fees, compensation arrangements or financial interests provided for in connection with the
transactions contemplated hereby is a fee or other compensation for the provision of investment advice, and that neither the Placement Agent nor any of its affiliates, nor any of their respective directors, officers, members, partners, employees,
principals or agents, has received or will receive a fee or other compensation from such Purchaser or such fiduciary for the provision of investment advice in connection with such Purchaser’s transactions contemplated by the Transaction
Documents. 

 4.15 Securities Laws Representations and Covenants of the Foreign Purchasers. 

(a) If the Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended, or
if the Purchaser is a US subsidiary or affiliate of a foreign parent company, the “Foreign Purchaser”), the Foreign Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction
in connection with any invitation to subscribe for the Shares or any use of this Agreement or the other Transaction Documents, including (i) the legal requirements within its jurisdiction for the purchase of the Shares, (ii) any foreign
exchange restrictions applicable to such purchase, (iii) any government or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption,
sale or transfer of the Shares. The Foreign Investor further represents that either (x) it does not now, nor will it after the Closing, hold ten percent (10%) or greater, directly or indirectly, of the voting interest in the Company or
(y) if it does or will, the Foreign Purchaser shall provide such information as the Company may request to comply with state, federal, or local regulations. The Company’s offer and sale and the Foreign Purchaser’s subscription and
payment for and continued beneficial ownership of the Shares will not violate any applicable securities or other laws of the Foreign Purchaser’s jurisdiction. 

(b) Each Foreign Purchaser represents and warrants to the Company as follows: 

(i) The Foreign Purchaser is not a “U.S. Person” (as defined under Regulation S of the Securities Act) and that the Shares to be
purchased by the Foreign Purchaser will be acquired for investment for the Investor’s own account, not as a nominee or agent, and not for the account or benefit of, a U.S. Person, and not with a view to the resale or distribution of any part
thereof in the United States and that the Foreign Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same. 

(ii) The Foreign Purchaser represents that it does not have any contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person in the United States or to a U.S. Person, or any hedging transaction with any third person in the United States or to a United States resident, with respect to any of the Shares.

 (iii) The Foreign Purchaser understands that the Shares are not registered under the Securities Act on the ground that the sale to the
Foreign Purchaser as provided for in this Agreement and the issuance of Shares to such Foreign Purchaser hereunder is exempt from registration under the Securities Act pursuant to Regulation S thereof, and that the Company’s reliance on such
exemption is predicated on the Foreign Purchaser’s representations set forth herein. The Foreign Purchaser hereby agrees to resell the Shares only in accordance with the provisions of Regulation S, pursuant to registration under the Securities
Act, or pursuant to an exemption from registration. The Foreign Purchaser further agrees not to engage in hedging transactions with regard to such Shares unless in compliance with the Securities Act. 

(c) The Foreign Purchaser has been informed, and it understands and agrees that a legend substantially similar to the one set forth below will
be placed on the certificates for the Shares and stop transfer instructions will be placed with the transfer agent of the Shares: 

“THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”),
OR UNDER THE SECURITIES LAWS OF ANY STATES IN THE UNITED STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES
LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT
AND ANY APPLICABLE STATE SECURITIES LAWS. FURTHER, THESE SECURITIES MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO 

 OR FOR THE ACCOUNT OR BENEFIT OF U.S. PERSONS (AS DEFINED IN REGULATION S UNDER THE
ACT) (I) AS PART OF THEIR DISTRIBUTION AT ANYTIME OR (II) OTHERWISE UNTIL THE EXPIRATION OF THE APPLICABLE RESTRICTED PERIOD AS DETERMINED IN ACCORDANCE WITH REGULATION S, EXCEPT IN EITHER CASE IN ACCORDANCE WITH REGULATIONS UNDER THE ACT.
IN ADDITION, NO HEDGING TRANSACTION MAY BE CONDUCTED WITH RESPECT TO THESE SHARES UNLESS SUCH TRANSACTIONS ARE IN COMPLIANCE WITH THE ACT.” 

4.16 Commissions. No Person will have, as a result of the transactions contemplated by the Transaction Documents, any valid right,
interest or claim against such Purchaser or upon the Company or any other Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of such Purchaser. Such Purchaser
shall pay, and hold the Company and other Purchasers harmless against, any liability, loss or expense (including, without limitation, reasonable attorney’s fees and
out-of-pocket expenses) arising in connection with any such claim for fees pursuant to any such agreement, arrangement or understanding entered into by or on behalf of
such Purchaser.     
 The Company acknowledges and agrees that the representations contained in ARTICLE 4 shall
not modify, amend or affect such Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any other Transaction Document or any other document
or instrument executed and/or delivered in connection with this Agreement or the consummation of the transaction contemplated hereby. 

ARTICLE 5 
 REGISTRATION
RIGHTS 
 5.1 Registration Statement.     

(a) On or prior to the Initial Filing Deadline, the Company shall prepare and file with the Commission a Registration Statement covering the
resale of all Registrable Securities for an offering to be made on a continuous basis pursuant to Rule 415. The Registration Statement shall be on Form S-1 (or, if applicable, on another appropriate form in
accordance with the Securities Act) and shall contain (except if otherwise required pursuant to written comments received from the Commission upon a review of such Registration Statement) the “Plan of Distribution” in substantially the
form attached hereto as Exhibit F. Notwithstanding any other provision of this ARTICLE 5, if the staff of the Commission does not permit all of the Registrable Securities to be registered on the initial Registration Statement filed
pursuant to this Section 5.1(a) (the “Initial Registration Statement”) or requires any Purchaser to be named as an “underwriter”, then the Company shall use commercially reasonable efforts to persuade the staff of the
Commission that the offering contemplated by the Registration Statement is a valid secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 and that none of the Purchasers is an
“underwriter”; provided, however, that in no event shall the Company be required to continue discussions with the staff of the Commission if the Company reasonably determines that doing so is reasonably likely to cause
the Company to incur liquidated damages pursuant to Section 5.1(d) because of a failure to have the Initial Registration Statement declared effective prior to the Initial Effectiveness Deadline. In the event that, despite the
Company’s commercially reasonable efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with the SEC Guidance, including without limitation, Securities Act Rules Compliance and
Disclosure Interpretation 612.09 and compliance with the terms of this Section 5.1(a), the staff of the Commission refuses to alter its position, the Company shall (i) remove from the Registration Statement such portion of the
Registrable Securities (the “Cut Back Shares”) as determined below and/or (ii) agree to such restrictions and limitations on the registration and resale of the Registrable Securities as the staff of the Commission may require
to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall not agree to name any Purchaser as an
“underwriter” in such Registration Statement without the prior written consent of such Purchaser; provided, further, that if any such Purchaser refuses to be named as an underwriter as required by the SEC Restrictions,
such Purchaser’s Registrable Securities shall be removed from the Initial Registration Statement and such Registrable Securities shall be deemed to constitute Cut Back Shares and the provisions of this Section 5.1(a) shall apply to
such Cut Back Shares. Except as provided in the immediately preceding sentence, any cut-back imposed pursuant to this Section 5.1(a) shall be allocated among the Purchasers on a pro rata basis by
removing Registrable Securities on a pro rata basis based on 

 the total number of unregistered Registrable Securities held by such Purchasers, in each case unless the SEC
Restrictions otherwise require or provide or the Purchasers otherwise agree. In the event of a cutback hereunder, the Company shall give each Purchaser at least three (3) Trading Days’ prior written notice along with the calculations as to
such Purchaser’s allotment. In furtherance of the foregoing, each Purchaser shall promptly notify the Company when it has sold substantially all of its Registrable Securities covered by the Initial Registration Statement (or any
Additional Registration Statement (as defined below)) so as to enable the Company to determine whether it can file one or more additional registration statements covering the Cut Back Shares and the Company agrees that it shall file one or more
additional Registration Statements (each, an “Additional Registration Statement”) as promptly as possible, and in any event on or prior to the applicable Additional Filing Deadline, successively using its commercially reasonable
efforts to register on each such Additional Registration Statement the maximum number of remaining Cut Back Shares that continue to constitute Registrable Securities until all of the Cut Back Shares that continue to constitute Registrable Securities
have been registered with the Commission. 
 (b) The Company shall use its commercially reasonable efforts to cause each Registration
Statement to be declared effective by the Commission as promptly as possible after the filing thereof, but in any event prior to the applicable Effectiveness Deadline, and shall use commercially reasonable efforts to keep the Registration Statement
continuously effective under the Securities Act until the earlier of (i) the date that all Registrable Securities covered by such Registration Statement have been sold or can be sold publicly without restriction or limitation under Rule 144
(including, without limitation, the requirement to be in compliance with Rule 144(c)(1)) or (ii) the date that is two (2) years following the Closing Date (the “Effectiveness Period”). Not later than two Trading Days after
a Registration Statement is declared effective, the Company shall file a prospectus supplement for any Registration Statement to the extent required pursuant to Rule 424. 

(c) The Company shall notify the Purchasers in writing promptly (and in any event within two Trading Days) after receiving notification from
the Commission that a Registration Statement has been declared effective. 
 (d) Should an Event (as defined below) occur, then upon the
occurrence of such Event and on every monthly anniversary thereof until the applicable Event is cured, the Company shall pay to each Purchaser an amount in cash, as liquidated damages and not as a penalty, equal to one percent (1.0%) of the
aggregate Share Purchase Price of the Registrable Securities then held by the Purchaser, subject to adjustment as provided below (which remedy shall be exclusive of any other remedies available under this Agreement or under applicable law);
provided, however, that the total amount of payments pursuant to this Section 5.1(d) shall not exceed, when aggregated with all such payments paid to the applicable Purchaser, five percent (5%) of the aggregate Share
Purchase Price hereunder. The payments to which a Purchaser shall be entitled pursuant to this Section 5.1(d) are referred to herein as “Event Payments.” Any Event Payments payable pursuant to the terms hereof shall
apply on a pro rated basis for any portion of a month prior to the cure of an Event. In the event the Company fails to make Event Payments in a timely manner, such Event Payments shall bear interest at the rate of one percent (1.0%) per month
(prorated for partial months) until paid in full. All pro rated calculations made pursuant to this paragraph shall be based upon the actual number of days in such pro rated month. The parties agree that the Company will not be liable for any Event
Payments under this Section 5.1(d) arising with respect to any period after the expiration of the Effectiveness Period. The parties further agree that Company will not be liable for any Event Payments under this Section 5.1(d) with
respect to any Cut Back Shares that are removed from a Registration Statement pursuant to Section 5.1(a); accordingly, any Event Payments shall be calculated, as to each Purchaser, to apply only to the percentage of such Purchaser’s
Registrable Securities that are both (x) then issued and outstanding and (y) permitted in accordance with SEC Guidance to be included in such Registration Statement. Notwithstanding the foregoing, the applicable Filing Deadline or
Effectiveness Deadline for a Registration Statement shall be extended without Event Payments hereunder in the event that the Company’s failure to file or obtain the effectiveness of such Registration Statement on a timely basis results from
(i) the failure of any Purchaser, other than a Purchaser that is also a director or officer of the Company, to timely provide the Company with information reasonably requested by the Company and necessary to complete the Registration Statement
in accordance with the requirements of the Securities Act or (ii) events or circumstances that are not in any way attributable to the Company’s actions or inactions, including, but not limited to, the failure of any Purchaser, other than a
Purchaser that is also a director or officer of the Company, to promptly notify the Company when it has sold substantially all of its Registrable Securities covered by the Initial Registration Statement or any Additional Registration Statement or to
otherwise comply with the terms of this Agreement, and in any event, no Purchaser causing the failure described in (i) or (ii), above shall be entitled to Event Payments relating to the failure caused by such Purchaser. 

 For such purposes, each of the following shall constitute an “Event”: 

(x) a Registration Statement is not filed on or prior to its Filing Deadline or is not declared effective on or prior to its Effectiveness
Deadline; and 
 (y) except as provided for in Section 5.1(e) (the “Excluded Events”), after the Effective Date of a
Registration Statement and through the end of the Effectiveness Period, a Purchaser is not permitted to sell the applicable Registrable Securities subject to such Registration Statement. 

(e) Notwithstanding anything in this Agreement to the contrary, the Company may, by written notice to the Purchasers, suspend sales under a
Registration Statement after the Effective Date thereof and/or require that the Purchasers immediately cease the sale of shares of Common Stock pursuant thereto and/or defer the filing of any Additional Registration Statement if the Company is
engaged in a material merger, acquisition or sale or any other pending development that the Company believes may be material, and the Board of Directors determines in good faith, by appropriate resolutions, that, as a result of such activity,
(A) it would be materially detrimental to the Company (other than as relating solely to the price of the Common Stock) to maintain a Registration Statement at such time or (B) it is in the best interests of the Company to suspend sales
under such registration at such time. Upon receipt of such notice, each Purchaser agrees to immediately discontinue any sales of Registrable Securities pursuant to such Registration Statement until such Purchaser is advised in writing by the Company
that the current Prospectus or amended Prospectus, as applicable, may be used. In no event, however, shall this right be exercised to suspend sales beyond the period during which (in the good faith determination of the Board of Directors) the
failure to require such suspension would be materially detrimental to the Company. The Company’s rights under this Section 5.1(e) may be exercised for a period of no more than 20 Trading Days at a time with a subsequent permitted
trading window of at least 90 Trading Days, and not more than two times in any twelve-month period. Immediately after the end of any suspension period under this Section 5.1(e), the Company shall take all necessary actions (including
filing any required supplemental prospectus) to restore the effectiveness of the applicable Registration Statement and the ability of the Purchasers to publicly resell their Registrable Securities pursuant to such effective Registration Statement.

 5.2 Registration Procedures. In connection with the Company’s registration obligations hereunder, the Company shall: 

(a) Not less than five Trading Days prior to the filing of a Registration Statement or any related Prospectus or any amendment or supplement
thereto, furnish via email to those Purchasers or their counsels who have supplied the Company with email addresses copies of all such documents proposed to be filed, which documents (other than any document that is incorporated or deemed to be
incorporated by reference therein) will be subject to the review of such Purchasers. The Company shall reflect in each such document when so filed with the Commission such comments regarding the Purchasers and the plan of distribution as the
Purchasers may reasonably and promptly propose no later than two Trading Days after the Purchasers have been so furnished with copies of such documents as aforesaid. 

(b) (i) Subject to Section 5.1(e), prepare and file with the Commission such amendments, including post-effective amendments,
to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep the Registration Statement continuously effective, as to the applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424; and (iii) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the applicable period in accordance with the intended methods of disposition by the Purchasers thereof set forth in the Registration Statement as so amended or in such Prospectus as
so supplemented. 

 (c) Notify the Purchasers as promptly as reasonably possible, and if requested by the
Purchasers, confirm such notice in writing no later than two Trading Days thereafter, of any of the following events: (i) the Commission notifies the Company whether there will be a “review” of any Registration Statement or the
receipt of any comments or correspondence from the Commission; (ii) any Registration Statement or any post-effective amendment is declared effective; (iii) the Commission issues any stop order suspending the effectiveness of any
Registration Statement or initiates any Proceedings for that purpose; (iv) the Company receives notice of any suspension of the qualification or exemption from qualification of any Registrable Securities for sale in any jurisdiction, or the
initiation or threat of any Proceeding for such purpose; (v) the financial statements included in any Registration Statement become ineligible for inclusion therein; or (vi) the Company becomes aware that any Registration Statement or
Prospectus or other document contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made,
not misleading. 
 (d) Use reasonable best efforts to avoid the issuance of or, if issued, obtain the withdrawal of (i) any order
suspending the effectiveness of any Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as soon as possible. 

(e) If requested by a Purchaser, provide such Purchaser, without charge, at least one conformed copy of each Registration Statement and each
amendment thereto, including financial statements and schedules, and all exhibits to the extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the
Commission; provided, that the Company shall have no obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system. 

(f) Promptly deliver to each Purchaser, without charge, as many copies of the Prospectus or Prospectuses (including each form of prospectus)
and each amendment or supplement thereto as such Persons may reasonably request. The Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Purchasers in connection with the offering and
sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto to the extent permitted by federal and state securities laws and regulations. 

(g) Prior to any resale of Registrable Securities by a Purchaser, use commercially reasonable best efforts to register or qualify or cooperate
with the selling Purchasers in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions
within the United States as any Purchaser requests in writing, to keep each such registration or qualification (or exemption therefrom) effective for so long as required, but not to exceed the duration of the Effectiveness Period, and to do any and
all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by a Registration Statement; provided, however, that the Company shall not be obligated to
file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction
in which it is not otherwise so subject. 
 (h) Use reasonable best efforts to cause all Registrable Securities covered by a Registration
Statement to be listed or quoted on the Trading Market; 
 (i) If requested by the Purchasers, cooperate with the Purchasers to facilitate
the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by this Agreement and under law,
of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Purchasers may reasonably request. 

(j) Upon the occurrence of any event described in Section 5.2(c)(iii)-(vi), as promptly as reasonably practicable, prepare a
supplement or amendment, including a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be 

 incorporated therein by reference, and file any other required document so that, as thereafter delivered,
neither the Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading. 
 (k) It shall be a condition precedent to the obligations of the Company to complete the
registration pursuant to this Agreement with respect to the Registrable Securities of any particular Purchaser that such Purchaser furnish to the Company a completed Selling Stockholder Questionnaire in the form proffered by the Company (the
“Selling Stockholder Questionnaire”) and such other information regarding itself, the Registrable Securities and other shares of Common Stock held by it and the intended method of disposition of the Registrable Securities held by it
(if different from the Plan of Distribution set forth on Exhibit F hereto) as shall be reasonably required to effect the registration of such Registrable Securities and shall complete and execute such documents in connection with such registration
as the Company may reasonably request.     
 (l) The Company shall comply with all applicable rules and regulations of
the Commission under the Securities Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final Prospectus, including any supplement or amendment thereof, with the Commission pursuant to Rule 424 under
the Securities Act, promptly inform the Purchasers in writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified in Rule 172 and, as a result thereof, the Purchasers are required to make available
a Prospectus in connection with any disposition of Registrable Securities and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder. 

(m) Not identify any Purchaser as an underwriter without its prior written consent in any public disclosure or filing with the Commission or
any Trading Market and any Purchaser being deemed an underwriter by the Commission shall not relieve the Company of any obligations it has under this Agreement; provided, however, that the foregoing shall not prohibit the Company from
including the disclosure found in the “Plan of Distribution” section attached hereto as Exhibit F in the Registration Statement. In addition, and notwithstanding anything to the contrary contained herein, if the Company has received
a comment by the Commission requiring a Purchaser to be named as an underwriter in the Registration Statement (which notwithstanding the reasonable best efforts of the Company is not withdrawn by the Commission) and such Purchaser refuses to be
named as an underwriter in the Registration Statement, such Purchaser’s Registrable Securities shall be removed from the Registration Statement, such Registrable Securities shall be deemed to constitute Cut Back Shares and the Purchaser shall
not be entitled to any Event Payments with respect to such Registration Statement. 
 5.3 Registration Expenses. The Company shall pay
all fees and expenses incident to the performance of or compliance with ARTICLE 5 of this Agreement by the Company, including without limitation (a) all registration and filing fees and expenses, including without limitation those
related to filings with the Commission, any Trading Market, and in connection with applicable state securities or Blue Sky laws, (b) printing expenses (including without limitation expenses of printing certificates for Registrable Securities),
(c) messenger, telephone and delivery expenses, (d) fees and disbursements of counsel for the Company, (e) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated
by this Agreement, (f) all listing fees to be paid by the Company to the Trading Market and (g) reasonable and reasonably-documented fees and disbursements, not to exceed $10,000 in the aggregate, of one counsel for the Purchasers. In no
event shall the Company be responsible for any underwriting, broker or similar fees or commissions of any Purchaser or, except to the extent provided for above or in the Transaction Documents, any legal fees or other costs of the Purchasers. 

5.4 Indemnification. 
 (a)
Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Purchaser, the officers, directors, partners, members, agents and employees of each of them, each Person
who controls any such Purchaser (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, agents and employees of each such controlling Person, to the fullest
extent permitted by applicable law, from and against any and all Losses, as incurred, arising out of or relating to any violation or alleged violation by the Company of the 

 Securities Act, the Exchange Act, any other law, including, without limitation, any state securities law, or
any rule or regulation thereunder relating to the offer or sale of the Registrable Securities, any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Prospectus or in any amendment or supplement
thereto, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in
the light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that (A) such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon
information regarding such Purchaser furnished in writing to the Company by such Purchaser expressly for use therein, or to the extent that such information relates to such Purchaser or such Purchaser’s proposed method of distribution of
Registrable Securities and was reviewed and expressly approved in writing by such Purchaser expressly for use in the Registration Statement, or (B) with respect to any Prospectus, if the untrue statement or omission of material fact contained
in such Prospectus was corrected on a timely basis in the Prospectus, as then amended or supplemented, if such corrected prospectus was timely made available by the Company to the Purchaser, and the Purchaser seeking indemnity hereunder was advised
in writing not to use the incorrect prospectus prior to the use giving rise to Losses. 
 (b) Indemnification by Purchasers. Each
Purchaser shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20
of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses (as determined by a court of competent jurisdiction in a final
judgment not subject to appeal or review) arising solely out of any untrue statement of a material fact contained in the Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto, or arising out of
or relating to any omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they
were made) not misleading, but only to the extent that such untrue statement or omission is contained in any information so furnished by such Purchaser in writing to the Company specifically for inclusion in such Registration Statement or such
Prospectus or to the extent that such untrue statements or omissions are based solely upon information regarding such Purchaser furnished to the Company by such Purchaser in writing expressly for use in the Registration Statement or Prospectus, or
to the extent that such information relates to such Purchaser or such Purchaser’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Purchaser expressly for use in the
Registration Statement (it being understood that the information provided by the Purchaser to the Company in the Questionnaire and the Plan of Distribution set forth on Exhibit F, as the same may be modified by such Purchaser constitutes information
reviewed and expressly approved by such Purchaser in writing expressly for use in the Registration Statement), such Prospectus or such form of Prospectus or in any amendment or supplement thereto. In no event shall the liability of any selling
Purchaser hereunder be greater in amount than the dollar amount of the net proceeds received by such Purchaser upon the sale of the Registrable Securities giving rise to such indemnification obligation. 

(c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity
hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall assume the defense
thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such
notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party. 

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (ii) the Indemnifying Party shall have failed within
15 days of receiving notification of a Proceeding from an Indemnified Party to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; (iii) any counsel engaged by
the applicable Indemnifying Party shall fail to timely commence or diligently conduct the defense of any such claim and such failure has materially prejudiced 

 (or, in the reasonable judgment of the Indemnified Party, is in danger of materially prejudicing) the
outcome of the applicable claim; or (iv) such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to or may exist between the applicable Indemnifying Party and Indemnified Party or that there may be one or
more different or additional defenses, claims, counterclaims or causes of action available to such Indemnified Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable fees and expenses of separate counsel shall be at the expense of the Indemnifying Party). It being understood,
however, that the Indemnifying Party shall not, in connection with any one such Proceeding (including separate Proceedings that have been or will be consolidated before a single judge) be liable for the fees and expenses of more than one separate
firm of attorneys at any time for all Indemnified Parties, which firm shall be appointed by a majority of the Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written
consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party,
unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding. 

All reasonable fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within 20 Trading Days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent
it is finally judicially determined (not subject to appeal) that such Indemnified Party is not entitled to indemnification hereunder). 
 (d)
Contribution. If a claim for indemnification under Section 5.4(a) or (b) is unavailable to an Indemnified Party (by reason of public policy or otherwise), then each Indemnifying Party, in lieu of indemnifying
such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in
connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among
other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying
Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be
deemed to include, subject to the limitations set forth in Section 5.4(c), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have
been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms. 

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5.4(d) were determined
by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 5.4(d), no
Purchaser shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such Purchaser from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any
damages that such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 
 The indemnity
and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties, including pursuant to Section 6.6 hereof. 

5.5 Dispositions. Each Purchaser agrees that it will comply with the prospectus delivery requirements of the Securities Act as
applicable to it in connection with sales of Registrable Securities pursuant to the Registration Statement and shall sell its Registrable Securities that it sells pursuant to the Registration Statement in accordance 

 with the Plan of Distribution set forth in the Prospectus. Each Purchaser further agrees that, upon receipt
of a notice from the Company of the occurrence of any event of the kind described in Section 5.2(c)(iii)-(vi), such Purchaser will discontinue disposition of such Registrable Securities under the Registration Statement until such
Purchaser is advised in writing by the Company that the use of the Prospectus, or amended Prospectus, as applicable, may be used. The Company may provide appropriate stop orders to enforce the provisions of this paragraph. Each Purchaser, severally
and not jointly with the other Purchasers, agrees that the removal of the restrictive legend from certificated or uncertificated Shares as set forth in Section 6.1 is predicated upon the Company’s reliance that the Purchaser will
comply with the provisions of this subsection. 
 5.6 No Piggyback on Registrations. Neither the Company nor any of its security
holders (other than the Purchasers in such capacity pursuant hereto) may include securities of the Company in the Registration Statement other than the Registrable Securities.    The Company shall not file any other registration
statements, other than any registration statements on Form S-4 or Form S-8 (each as promulgated under the Securities Act), prior to the Effective Date of the Initial
Registration Statement, provided that this Section 5.6 shall not prohibit the Company from filing amendments to registration statements filed prior to the date of this Agreement. 

5.7 Amendments; Waivers. Notwithstanding anything in this Agreement to the contrary, the provisions of this ARTICLE 5 may be
amended or waived (either generally or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely), with the written consent of (i) the Company and (ii) the Purchaser or
Purchasers holding at least a majority of the then outstanding Registrable Securities. Notwithstanding the foregoing, a waiver or consent to depart from the provisions of this ARTICLE 5 with respect to a matter that relates exclusively to the
rights of Purchasers and that does not directly or indirectly affect the rights of other Purchasers may be given by Purchasers of all of the Registrable Securities to which such waiver or consent relates; provided, however, that the
provisions of this sentence may not be amended, modified or supplemented except in accordance with the provisions of the immediately preceding sentence. 

ARTICLE 6 
 OTHER
AGREEMENTS OF THE PARTIES 
 6.1 Transfer Restrictions. 

(a) The Shares may only be disposed of in compliance with state and federal securities laws, and each Purchaser agrees that it will sell,
transfer or otherwise dispose of the Shares only in compliance with all applicable state and federal securities laws, and, as applicable, in accordance with the requirements of Section 5.5 hereof. In connection with any transfer of
Shares other than pursuant to an effective registration statement under the Securities Act or Rule 144, to the Company or to an Affiliate of a Purchaser, the Company may require the transferor thereof to provide to the Company an opinion of counsel
selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Shares
under the Securities Act. 
 (b) The Purchasers agree to the imprinting, so long as is required by this Section 6.1, of a legend
on any of the Shares, whether in certificated or uncertificated form, in substantially the following forms, as applicable: 

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE
OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT EXCEPT PURSUANT TO A TRANSACTION EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE ACT 

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER IN FAVOR OF THE CORPORATION AND/OR ITS
ASSIGNEE(S), AS PROVIDED IN THE BYLAWS OF THE CORPORATION. 

 In addition, if any Purchaser is an Affiliate of the Company, the Shares issued to such
Purchaser shall bear a customary “affiliates” legend. 
 (c) Instruments, whether certificated or uncertificated, evidencing the
Shares shall not contain any legend (including the legends set forth in Section 6.1(b) hereof), (i) while a registration statement (including the Registration Statement) covering the resale of such Shares is effective under the
Securities Act, (ii) if such Shares are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such Shares and without volume or manner-of-sale restrictions, (iii) following any sale of such Shares pursuant to Rule 144 or (iv) if such legend is not required under applicable requirements of the
Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) or otherwise. Upon request by any Purchaser, following such time as a legend is no longer required under this Section 6.1(c),
the Company shall cause its counsel to issue a legal opinion to the Transfer Agent (if required by the Transfer Agent) to effect the removal of the legend hereunder from any Shares. The Company agrees that following such time as a legend is no
longer required under this Section 6.1(c), no later than three Trading Days following the delivery by a Purchaser to the Company of all of (i) an instrument, whether certificated or uncertificated, representing the Shares issued
with a restrictive legend, (ii) a written request addressed to the Company that such restrictive legend be removed, and (iii) customary broker and representation letters in form and substance reasonably satisfactory to the Company (the
date that all of such foregoing information and documentation is delivered to the Company by a Purchaser, the “Removal Request Date” and such third Trading Day thereafter, the “Legend Removal Date”), the Company
will deliver or cause to be delivered to such Purchaser an instrument, certificated or uncertificated as directed by such Purchaser, representing such Shares that is free from all restrictive and other legends. The Company may not make any notation
on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 6.1(c). Shares subject to legend removal hereunder shall, unless otherwise directed by a Purchaser, be
transmitted by the Transfer Agent to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser. 

(d) In addition to a Purchaser’s other available remedies, if the Company shall fail for any reason (other than failure of such Purchaser
to comply with the provisions set forth in Section 6.1) to deliver any Shares without a restrictive legend by the Legend Removal Date, and if on or after the Legend Removal Date such Purchaser purchases (in an open market transaction or
otherwise) shares of Common Stock to deliver in satisfaction of a sale by such Purchaser of any portion of such Shares that such Purchaser anticipated receiving without legend by the Legend Removal Date (a
“Buy-In”), then the Company shall, within two (2) Trading Days after such Purchaser’s request and in such Purchaser’s discretion, either: (i) pay cash to such Purchaser in
an amount equal to such Purchaser’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased by such Purchaser (the “Buy-In Price”), at
which point the Company’s obligation to deliver such unlegended Shares shall terminate, or (ii) promptly honor its obligation to deliver to such Purchaser such unlegended Shares as provided above and pay cash to such Purchaser in an amount
equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Shares, times (B) the Fair Market Value of one share of Common Stock as of the Removal Request Date. 

6.2 Furnishing of Information; Public Information. In order to enable the Purchasers to sell Shares under Rule 144, for a period of one
year from the effective date of the Company’s Initial Registration Statement, the Company covenants to use commercially reasonable efforts to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all
reports that would be required to be filed by the Company after the effective date of the Company’s Initial Registration Statement pursuant to Section 13(a) or 15(d) of the Exchange Act. During such one year period, if the Company is not
required to file reports pursuant to Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the Holders and make publicly available in accordance with Rule 144(c) promulgated under the Securities Act annual and quarterly
financial statements, together with a discussion and analysis of such financial statements in form and substance substantially similar to those that would otherwise be required to be included in reports required by Section 13(a) or 15(d) of the
Exchange Act, as well as any other information required thereby, in the time period that such filings would have been required to have been made under the Exchange Act. 

6.3 Use of Proceeds. The Company shall use the net proceeds from the sale of the Shares hereunder for funding research and development
and its other operations, or for working capital and other general corporate purposes, and shall not use any such proceeds in violation of FCPA or OFAC regulations. For clarity, the net proceeds will not be used to repurchase existing stockholder
shares or to pay down non-revolving debt. 
  

 6.4 Indemnification of Purchasers. Subject to the provisions of this
Section 6.4, the Company will indemnify and hold each Purchaser and its directors, officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles
notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders,
agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling Persons (each, a “Purchaser
Party”) harmless from any and all Losses that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this
Agreement or in the other Transaction Documents or (b) any action instituted against the Purchaser Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such
Purchaser Parties, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is found by a court of competent jurisdiction in a final, non-appealable decision to be
based upon a breach of such Purchaser Party’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser Parties may have with any such stockholder or any violations by such
Purchaser Parties of state or federal securities laws or any conduct by such Purchaser Parties which constitutes fraud, gross negligence, willful misconduct or malfeasance of such Purchaser Party). If any action shall be brought against any
Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own
choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense
of such Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ
counsel reasonably acceptable to such Purchaser Party or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser
Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement by a
Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is found by a court of
competent jurisdiction in a final, non-appealable decision to be attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser
Party in this Agreement or in the other Transaction Documents. No Purchaser shall be liable for the indemnification obligations of any other Purchaser and no Purchaser’s liability shall exceed the purchase price paid for the Shares pursuant to
this Agreement. The indemnification required by this Section 6.4 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity
agreements contained herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others and any liabilities the Company may be subject to pursuant to law. 

6.5 Reservation of Common Stock. The Company has reserved and the Company shall continue to reserve and keep available at all times,
free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue the Shares pursuant to this Agreement (the “Required Minimum”). If, on any date, the number of authorized but
unissued (and otherwise unreserved) shares of Common Stock is less than the Required Minimum on such date, then, not later than the Company’s next annual meeting of stockholders occurring on or after the 60th day following such date, the Board
of Directors shall use commercially reasonable efforts to amend the Company’s certificate of incorporation to increase the number of authorized but unissued shares of Common Stock to at least the Required Minimum at such time. 

6.6 Listing of Common Stock; Uplisting to The NASDAQ Capital Market. The Company will use its commercially reasonable efforts to effect
the quotation of its Common Stock on the OTC and will comply in all material respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the applicable OTC trading market, and will use its commercially
reasonable efforts to effect an uplisting to NASDAQ as soon as reasonably practicable. In addition, the Purchasers and the Company agree to cooperate in good faith, if 

 necessary, to restructure the transactions contemplated by the Transaction Documents such that they do not
contravene the rules and regulations of the Principal Trading Market; provided, however, that such restructuring does not impact the economic interests of the Purchasers contemplated by the Transaction Documents. Each Purchaser agrees
to provide information reasonably requested by the Company to comply with this Section 6.6. The provisions of this Section 6.6 shall terminate and be of no further force and effect upon the expiration of the Effectiveness
Period. 
 6.7 Equal Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall be
offered or paid to any Person to amend or consent to a waiver or modification of any provision of this Agreement unless the same consideration is also offered to all of the parties to this Agreement. For clarification purposes, this provision
constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in
concert or as a group with respect to the purchase, disposition or voting of Shares or otherwise. 
 6.8 Form D; Blue Sky Filings. The
Company agrees to timely file a Form D with respect to the Shares as required under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall reasonably determine is
necessary in order to obtain an exemption for, or to qualify the Shares for, sale to the Purchasers at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such
actions promptly upon request of any Purchaser. Each Purchaser shall provide any information reasonably requested by the Company to comply with this Section 6.18. 

6.9 Acknowledgment Regarding Purchaser’s Trading Activity. Anything in this Agreement or elsewhere herein to the contrary
notwithstanding (except for Section 4.3), it is understood and acknowledged by the Company that: (i) none of the Purchasers has been asked by the Company to agree, nor has any Purchaser agreed, to desist from purchasing or selling, long
and/or short, securities of the Company, or “derivative” securities based on securities issued by the Company or to hold the Shares for any specified term, (ii) past or future open market or other transactions by any Purchaser,
specifically including, without limitation, Short Sales or “derivative” transactions, before or after the closing of this or future private placement transactions, may negatively impact the market price of the Company’s
publicly-traded securities, (iii) any Purchaser, and counter-parties in “derivative” transactions to which any such Purchaser is a party, directly or indirectly, may presently have a “short” position in the Common Stock and
(iv) each Purchaser shall not be deemed to have any affiliation with or control over any arm’s length counter-party in any “derivative” transaction. The Company further understands and acknowledges that (y) one or more
Purchasers may engage in hedging activities at various times during the period that the Shares are outstanding, and (z) such hedging activities (if any) could reduce the value of the existing stockholders’ equity interests in the Company
at and after the time that the hedging activities are being conducted. Except as contemplated by Section 4.3 hereof, Company acknowledges that such aforementioned hedging activities do not constitute a breach of any of the Transaction
Documents. 
 6.10 Other Actions. Except as otherwise set forth in this Agreement, from the date of this Agreement until the earlier
to occur of the Closing or the termination of this Agreement in accordance with the terms hereof, the Company and the Purchasers shall not, and shall not permit any of their respective Affiliates to, take, or agree or commit to take, any action that
would reasonably be expected to, individually or in the aggregate, prevent, materially delay or materially impede the consummation of the transactions contemplated by this Agreement. 

ARTICLE 7 
 MISCELLANEOUS

 7.1 Fees and Expenses. Except as set forth in Section 5.3, the parties hereto shall pay their own costs and expenses in
connection herewith, including all attorneys’ fees.     
 7.2 Entire Agreement. The Transaction Documents,
together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, oral or written, with respect to such
matters, which the parties acknowledge have been merged into such documents, exhibits and schedules; provided, however, that any nondisclosure or 

 confidentiality agreement previously entered into between the Company and any Purchaser(s) shall remain in
full force and effect. At or after the Closing, and without further consideration, the Company will execute and deliver to the Purchasers, and the Purchasers will execute and deliver to the Company, such further documents as may be reasonably
requested in order to give practical effect to the intention of the parties under the Transaction Documents.     
 7.3
Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of: (a) the date of transmission, if such
notice or communication is delivered via facsimile at the facsimile number or by electronic mail at the email address set forth on the signature pages attached hereto at or prior to 5:30 p.m. (New York City time) on a Trading Day, (b) the next
Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number or by electronic mail at the email address set forth on Exhibit A attached hereto on a day that is not a Trading
Day or later than 5:30 p.m. (New York City time) on any Trading Day, (c) the second (2nd) Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier service or (d) upon actual receipt by the party to

 (i) if to the Company, to
Sonim Technologies, Inc., 1875 South Grant Street, Suite 750, San Mateo, California, Attention: Chief Executive Officer, (facsimile: (650) 378-8109), with a copy to Cooley LLP, 3175 Hanover Street, Palo Alto,
California 94304 (facsimile: (650) 849-7400), Attention: Jon E. Gavenman; and 
 (ii) if to the
Purchasers, to their respective addresses as set forth on Exhibit A attached hereto. 
 7.4 Amendments; Waivers. Subject to the
provisions of Section 5.7, no provision of this Agreement may be waived, modified, supplemented or amended except in a written instrument signed, in the case of an amendment, by the Company and the Principal Purchasers or, in the case of
a waiver, by the party against whom enforcement of any such waived provision is sought, provided, however, that any proposed amendment or waiver that disproportionately, materially and adversely affects the rights and obligations of
any Purchaser relative to the comparable rights and obligations of the other Purchasers shall require the prior written consent of such adversely affected Purchaser. No waiver of any default with respect to any provision, condition or requirement of
this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right
hereunder in any manner impair the exercise of any such right. Any amendment effected in accordance with accordance with this Section 7.4 shall be binding upon each Purchaser and the Company. 

7.5 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit
or affect any of the provisions hereof. 
 7.6 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit
of the parties and their successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of each Purchaser. With the consent of the Company which will not be
unreasonably withheld, any Purchaser may assign any or all of its rights under this Agreement to any Person to whom such Purchaser assigns or transfers any Shares, provided, that a Purchaser may assign any or all rights under this Agreement
to an Affiliate of such Purchaser without the consent of the Company, and provided, further: (i) such transferor agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to
the Company after such assignment; (ii) the Company is furnished with written notice of (x) the name and address of such transferee or assignee and (y) if the transferor is assigning any registration rights under ARTICLE 5
hereof, the Registrable Securities with respect to which such registration rights are being transferred or assigned; (iii) following such transfer or assignment, the further disposition of such securities by the transferee or assignee is
restricted under the Securities Act and applicable state securities laws, unless such disposition was made pursuant to an effective registration statement or an exemption under Rule 144 under the Securities Act; (iv) such transferee agrees in
writing to be bound, with respect to the transferred Shares, by the provisions of the Transaction Documents that apply to the “Purchasers” including, without limitation, all of representations, warranties and agreements set forth in
ARTICLE 4 hereof; and (v) such transfer shall have been made in accordance with the applicable requirements of this Agreement and with all laws applicable thereto. 

 7.7 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the
parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Sections 5.4 and 6.4 and this
Section 7.7. In addition, the Placement Agent shall be an intended third party beneficiary of (i) the Company’s representations and warranties set forth in ARTICLE 3 hereof and (ii) each Purchaser’s
representations, warranties and agreements set forth in ARTICLE 4 hereof, including Section 4.8 hereof. 
 7.8
Governing Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York without regard to the choice of law principles thereof. Each of the parties hereto irrevocably
submits to the exclusive jurisdiction of the state and federal courts located in the State of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby.
Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the parties hereto
irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or
proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. If any party hereto shall commence an Action or Proceeding to enforce
any provisions of the Transaction Documents, then, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing party for its reasonable attorneys’ fees and other costs and
expenses incurred with the investigation, preparation and prosecution of such Action or Proceeding. 
 7.9 WAIVER OF JURY
TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY,
UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY. 
 7.10 Survival. The representations and warranties
contained herein shall survive the Closing and the delivery of the Shares. 
 7.11 Execution. This Agreement may be executed in two or
more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being understood that the parties
need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. 

7.12 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall
use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be
the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 

7.13 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions
of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then
such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights. 

 7.14 Replacement of Shares. If any certificate or instrument evidencing any Shares is
mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument,
but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including
customary indemnity) associated with the issuance of such replacement Shares. 
 7.15 Remedies. In addition to being entitled to
exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be
adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a
remedy at law would be adequate. 
 7.16 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each
Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the
obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereof or thereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction
Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any
other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Documents. The Company has elected to
provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by any of the Purchasers.     

7.17 Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision, dividend or distribution payable in shares
of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date hereof, each
reference in any Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such event. 

7.18 Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the
Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such
partial liquidated damages or other amounts are due and payable shall have been canceled. 
 7.19 Waiver of Conflicts. Each party to
this Agreement acknowledges that Cooley LLP (“Cooley”), outside general counsel to the Company, has in the past performed and is or may now or in the future represent one or more Purchasers or their affiliates in matters unrelated
to the transactions contemplated by this Agreement (the “Offering”), including representation of such Purchasers or their affiliates in matters of a similar nature to the Offering. The applicable rules of professional conduct
require that Cooley inform the parties hereunder of this representation and obtain their consent. Cooley has served as outside general counsel to the Company and has negotiated the terms of the Offering solely on behalf of the Company. The Company
and each Purchaser hereby (a) acknowledge that they have had an opportunity to ask for and have obtained information relevant to such representation, including disclosure of the reasonably foreseeable adverse consequences of such
representation; (b) acknowledge that with respect to the Offering, Cooley has represented solely the Company, and not any Purchaser or any stockholder, director or employee of the Company or any Purchaser; and (c) gives its informed
consent to Cooley’s representation of the Company in the Offering.

 EXHIBIT F 

PLAN OF DISTRIBUTION 
 We
are registering the shares of common stock issued to the selling stockholders to permit the resale of these shares of common stock by the selling stockholders from time to time from after the date of this prospectus. We will not receive any of the
proceeds from the sale by the selling stockholders of the shares of common stock. We will bear all fees and expenses incident to our obligation to register the shares of common stock. 

Each selling stockholder may, from time to time, sell any or all of their shares of common stock covered hereby on The NASDAQ Global Market or
any other stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of
sale, or privately negotiated prices. A selling stockholder may use any one or more of the following methods when selling shares: 
  

	 	•	 	 ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

  

	 	•	 	 block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a
portion of the block as principal to facilitate the transaction; 

  

	 	•	 	 purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 

 

	 	•	 	 an exchange distribution in accordance with the rules of the applicable exchange; 

 

	 	•	 	 privately negotiated transactions; 

 

	 	•	 	 settlement of short sales, to the extent permitted by law; 

 

	 	•	 	 in transactions through broker-dealers that agree with the selling stockholders to sell a specified number of
such shares at a stipulated price per share; 

  

	 	•	 	 through the writing or settlement of options or other hedging transactions, whether through an options exchange
or otherwise; 

  

	 	•	 	 a combination of any such methods of sale; or 

 

	 	•	 	 any other method permitted pursuant to applicable law. 

The selling stockholders may also sell the shares of common stock under Rule 144 under the Securities Act, if available, rather than under
this prospectus. 
 Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales.
Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this
prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440-1. 
 In connection with the sale of the shares of common
stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares of common stock in the course of hedging the
positions they assume. The selling stockholders may also sell the shares of common stock short and deliver these securities to close out their short positions or to return borrowed shares in connection with such short sales, or loan or pledge the
shares of common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative
securities which require the delivery to such broker-dealer or other financial institution of shares of common stock offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus
(as supplemented or amended to reflect such transaction). 

 The selling stockholders and any broker-dealers or agents that are involved in selling the
shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such selling stockholders, broker-dealers or agents and any profit
on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act
will be subject to the prospectus delivery requirements of the Securities Act and may be subject to certain statutory liabilities of, including but not limited to, Sections 11, 12 and 17 of the Securities Act and Rule
10b-5 under the Exchange Act. Each selling stockholder has informed us that it is not a registered broker-dealer or an affiliate of a registered broker-dealer. In no event shall any broker-dealer receive fees,
commissions and markups which, in the aggregate, would exceed eight percent (8%). 
 We are required to pay certain fees and expenses
incurred by us incident to the registration of the shares. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act, and the selling stockholders may
be entitled to contribution. We may be indemnified by the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act that may arise from any written information furnished to us by the
selling stockholders specifically for use in this prospectus, or we may be entitled to contribution. 
 The selling stockholders will be
subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder unless an exemption therefrom is available. 

We agreed to cause the registration statement of which this prospectus is a part to remain effective until the earlier to occur of [•] or
the date on which all of the shares registered hereby are either sold pursuant to the registration statement or sold or available for resale without restriction under Rule 144 under the Securities Act. The shares of common stock will be sold only
through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the shares of common stock covered hereby may not be sold unless they have been registered or qualified for sale in
the applicable state or an exemption from the registration or qualification requirement is available and is complied with. 
 Under
applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the shares of common stock may not simultaneously engage in market making activities with respect to the shares of common stock for the applicable
restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including
Regulation M, which may limit the timing of purchases and sales of shares of common stock by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the
need to deliver a copy of this prospectus at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act). 

There can be no assurance that any selling stockholder will sell any or all of the shares of common stock we registered on behalf of the
selling stockholders pursuant to the registration statement of which this prospectus forms a part. 
 Once sold under the registration
statement of which this prospectus forms a part, the shares of common stock will be freely tradable in the hands of persons other than our affiliates.EX-10.1

Awards, (v) Restricted Stock Unit Awards and (vi) Other Stock Awards. 
 (c) Purpose. The Plan, through the granting

the eligible recipients may benefit from increases in value of the Common Stock. 
 2. ADMINISTRATION. 

(a) Administration by Board. The Board will administer the Plan. The Board may delegate administration of the Plan to a Committee or
Committees, as provided in Section 2(c). 
 (b) Powers of Board. The Board will have the power, subject to, and within the
limitations of, the express provisions of the Plan: 
 (i) To determine (A) who will be granted Stock Awards; (B) when and
how each Stock Award will be granted; (C) what type of Stock Award will be granted; (D) the provisions of each Stock Award (which need not be identical), including when a person will be permitted to exercise or otherwise receive cash or
Common Stock under the Stock Award; (E) the number of shares of Common Stock subject to a Stock Award; and (F) the Fair Market Value applicable to a Stock Award. 

(ii) To construe and interpret the Plan and Stock Awards granted under it, and to establish, amend and revoke rules and regulations for
administration of the Plan and Stock Awards. The Board, in the exercise of these powers, may correct any defect, omission or inconsistency in the Plan or in any Stock Award Agreement, in a manner and to the extent it will deem necessary or expedient
to make the Plan or Stock Award fully effective. 

  
 1. 

 (iii) To settle all controversies regarding the Plan and Stock Awards granted under
it. 
 (iv) To accelerate, in whole or in part, the time at which a Stock Award may be exercised or vest (or at which cash or shares
of Common Stock may be issued). 
 (v) To suspend or terminate the Plan at any time. Except as otherwise provided in the Plan or a
Stock Award Agreement, suspension or termination of the Plan will not impair a Participant’s rights under his or her then-outstanding Stock Award without his or her written consent except as provided in subsection (viii) below. 

(vi) To amend the Plan in any respect the Board deems necessary or advisable, including, without limitation, by adopting amendments
relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or to make the Plan or Stock Awards granted under the Plan compliant with the requirements for Incentive Stock Options or
exempt from or compliant with the requirements for nonqualified deferred compensation under Section 409A of the Code, subject to the limitations, if any, of applicable law. However, if required by applicable law, and except as provided in
Section 9(a) relating to Capitalization Adjustments, the Company will seek stockholder approval of any amendment of the Plan that (A) materially increases the number of shares of Common Stock available for issuance under the Plan,
(B) materially expands the class of individuals eligible to receive Stock Awards under the Plan, (C) materially increases the benefits accruing to Participants under the Plan, (D) materially reduces the price at which shares of Common
Stock may be issued or purchased under the Plan, (E) materially extends the term of the Plan, or (F) materially expands the types of Stock Awards available for issuance under the Plan. Except as provided in the Plan (including subsection
(viii) below) or a Stock Award Agreement, no amendment of the Plan will impair a Participant’s rights under an outstanding Stock Award unless (1) the Company requests the consent of the affected Participant, and (2) such
Participant consents in writing. 
 (vii) To submit any amendment to the Plan for stockholder approval, including, but not limited to,
amendments to the Plan intended to satisfy the requirements of Section 422 of the Code regarding Incentive Stock Options. 
 (viii)
To approve forms of Stock Award Agreements for use under the Plan and to amend the terms of any one or more Stock Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in
the Stock Award Agreement, subject to any specified limits in the Plan that are not subject to Board discretion; provided however, that a Participant’s rights under any Stock Award will not be impaired by any such amendment unless
(A) the Company requests the consent of the affected Participant, and (B) such Participant consents in writing. Notwithstanding the foregoing, (1) a Participant’s rights will not be deemed to have been impaired by any such
amendment if the Board, in its sole discretion, determines that the amendment, taken as a whole, does not materially impair the Participant’s rights, and (2) subject to the limitations of applicable law, if any, the Board may amend the
terms of any one or more Stock Awards without the affected Participant’s consent (A) to maintain the qualified status of the Stock Award as an Incentive Stock Option under Section 422 of the Code; (B) to change the terms of an
Incentive Stock Option, if such change 

  
 2. 

 
results in impairment of the Award solely because it impairs the qualified status of the Award as an Incentive Stock Option under Section 422 of the Code; (C) to clarify the manner of
exemption from, or to bring the Stock Award into compliance with, Section 409A of the Code; or (D) to comply with other applicable laws. 

(ix) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests
of the Company and that are not in conflict with the provisions of the Plan or Stock Awards. 
 (x) To adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Employees, Directors or Consultants who are foreign nationals or employed outside the United States (provided that Board approval will
not be necessary for immaterial modifications to the Plan or any Stock Award Agreement that are required for compliance with the laws of the relevant foreign jurisdiction). 

(xi) To effect, with the consent of any adversely affected Participant, (A) the reduction of the exercise, purchase or strike price
of any outstanding Stock Award; (B) the cancellation of any outstanding Stock Award and the grant in substitution therefor of a new (1) Option or SAR, (2) Restricted Stock Award, (3) Restricted Stock Unit Award, (4) Other
Stock Award, (5) cash and/or (6) other valuable consideration determined by the Board, in its sole discretion, with any such substituted award (x) covering the same or a different number of shares of Common Stock as the cancelled
Stock Award and (y) granted under the Plan or another equity or compensatory plan of the Company; or (C) any other action that is treated as a repricing under generally accepted accounting principles. 

(c) Delegation to Committee. The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If
administration of the Plan is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to
delegate to a subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee). Any delegation of administrative
powers will be reflected in resolutions, not inconsistent with the provisions of the Plan, adopted from time to time by the Board or Committee (as applicable). The Committee may, at any time, abolish the subcommittee and/or revest in the Committee
any powers delegated to the subcommittee. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously delegated. 

(d) Delegation to an Officer. The Board may delegate to one (1) or more Officers the authority to do one or both of the
following: (i) designate Employees who are not Officers to be recipients of Options and SARs (and, to the extent permitted by applicable law, other Stock Awards) and, to the extent permitted by applicable law, the terms of such Stock Awards,
and (ii) determine the number of shares of Common Stock to be subject to such Stock Awards granted to such Employees; provided, however, that the Board resolutions regarding such delegation will specify the total number of shares of Common
Stock that may be subject to the Stock Awards granted by such Officer and that such Officer may not grant a Stock Award to himself or herself. 

  
 3. 

 
Any such Stock Awards will be granted on the form of Stock Award Agreement most recently approved for use by the Committee or the Board, unless otherwise provided in the resolutions approving the
delegation authority. The Board may not delegate authority to an Officer who is acting solely in the capacity of an Officer (and not also as a Director) to determine the Fair Market Value pursuant to Section 13(t) below.  

(e) Effect of Board’s Decision. All determinations, interpretations and constructions made by the Board in
good faith will not be subject to review by any person and will be final, binding and conclusive on all persons. 
 3. Shares Subject to the Plan.

 (a) Share Reserve. 

(i) Subject to Section 9(a) relating to Capitalization Adjustments, the aggregate number of shares of Common Stock that may be
issued pursuant to Stock Awards from and after the Effective Date will not exceed Twenty-Seven Million Forty Thousand (27,040,000) shares (the “Share Reserve”). 

(ii) For clarity, the Share Reserve in this Section 3(a) is a limitation on the number of shares of Common Stock that may be issued
pursuant to the Plan. Accordingly, this Section 3(a) does not limit the granting of Stock Awards except as provided in Section 7(a). 

(b) Reversion of Shares to the Share Reserve. If a Stock Award or any portion thereof (i) expires or otherwise terminates without
all of the shares covered by such Stock Award having been issued or (ii) is settled in cash (i.e., the Participant receives cash rather than stock), such expiration, termination or settlement will not reduce (or otherwise offset) the
number of shares of Common Stock that may be available for issuance under the Plan. If any shares of Common Stock issued pursuant to a Stock Award are forfeited back to or repurchased by the Company because of the failure to meet a contingency or
condition required to vest such shares in the Participant, then the shares that are forfeited or repurchased will revert to and again become available for issuance under the Plan. Any shares reacquired by the Company in satisfaction of tax
withholding obligations on a Stock Award or as consideration for the exercise or purchase price of a Stock Award will again become available for issuance under the Plan. 

(c) Incentive Stock Option Limit. Subject to the Share Reserve and Section 9(a) relating to Capitalization Adjustments, the
aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options will be equal to two (2) times the Share Reserve set forth in Section 3(a)(i) above. 

(d) Source of Shares. The stock issuable under the Plan will be shares of authorized but unissued or reacquired Common Stock, including
shares repurchased by the Company on the open market or otherwise. 

  
 4. 

 4. ELIGIBILITY. 

(a) Eligibility for Specific Stock Awards. Incentive Stock Options may be granted only to employees of the Company or a “parent
corporation” or “subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and 424(f) of the Code). Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants;
provided, however, that Stock Awards may not be granted to Employees, Directors and Consultants who are providing Continuous Service only to any “parent” of the Company, as such term is defined in Rule 405, unless (i) the
stock underlying such Stock Awards is treated as “service recipient stock” under Section 409A of the Code (for example, because the Stock Awards are granted pursuant to a corporate transaction such as a spin off transaction), or
(ii) the Company, in consultation with its legal counsel, has determined that such Stock Awards are otherwise exempt from or alternatively comply with the distribution requirements of Section 409A of the Code. 

(b) Ten Percent Stockholders. A Ten Percent Stockholder will not be granted an Incentive Stock Option unless the exercise price of such
Option is at least one hundred ten percent (110%) of the Fair Market Value on the date of grant and the Option is not exercisable after the expiration of five (5) years from the date of grant. 

(c) Consultants. A Consultant will not be eligible for the grant of a Stock Award if, at the time of grant, either the offer or sale of
the Company’s securities to such Consultant is not exempt under Rule 701 because of the nature of the services that the Consultant is providing to the Company, because the Consultant is not a natural person, or because of any other
provision of Rule 701, unless the Company determines that such grant need not comply with the requirements of Rule 701 and will satisfy another exemption under the Securities Act as well as comply with the securities laws of all other
relevant jurisdictions. 
 5. PROVISIONS RELATING TO OPTIONS AND
STOCK APPRECIATION RIGHTS. 
 Each Option or SAR will be in such form and will contain such
terms and conditions as the Board deems appropriate. All Options will be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates will
be issued for shares of Common Stock purchased on exercise of each type of Option. If an Option is not specifically designated as an Incentive Stock Option, or if an Option is designated as an Incentive Stock Option but some portion or all of the
Option fails to qualify as an Incentive Stock Option under the applicable rules, then the Option (or portion thereof) will be a Nonstatutory Stock Option. The provisions of separate Options or SARs need not be identical; provided, however,
that each Stock Award Agreement will conform to (through incorporation of provisions hereof by reference in the applicable Stock Award Agreement or otherwise) the substance of each of the following provisions: 

(a) Term. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, no Option or SAR will be exercisable after
the expiration of ten (10) years from the date of its grant or such shorter period specified in the Stock Award Agreement. 

  
 5. 

 (b) Exercise Price. Subject to the provisions of Section 4(b) regarding Ten
Percent Stockholders, the exercise or strike price of each Option or SAR will be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Stock Award is granted.
Notwithstanding the foregoing, an Option or SAR may be granted with an exercise or strike price lower than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Stock Award if such Stock Award is granted
pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Corporate Transaction and in a manner consistent with the provisions of Section 409A of the Code and, if applicable, Section 424(a)
of the Code. Each SAR will be denominated in shares of Common Stock equivalents. 
 (c) Purchase Price for Options. The purchase price
of Common Stock acquired pursuant to the exercise of an Option may be paid, to the extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board will
have the authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to use a particular method of
payment. The permitted methods of payment are as follows: 
 (i) by cash, check, bank draft or money order payable to the Company;

 (ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the
issuance of the stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds; 

(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock; 

(iv) if an Option is a Nonstatutory Stock Option, by a “net exercise” arrangement pursuant to which the Company will reduce
the number of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company will accept a cash or other payment
from the Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued. Shares of Common Stock will no longer be subject to an Option and will not be
exercisable thereafter to the extent that (A) shares issuable upon exercise are used to pay the exercise price pursuant to the “net exercise,” (B) shares are delivered to the Participant as a result of such exercise, and
(C) shares are withheld to satisfy tax withholding obligations; 
 (v) according to a deferred payment or similar arrangement
with the Optionholder; provided, however, that interest will compound at least annually and will be charged at the minimum rate of interest necessary to avoid (A) the imputation of interest income to the Company and compensation income
to the Optionholder under any applicable provisions of the Code, and (B) the classification of the Option as a liability for financial accounting purposes; or 

  
 6. 

 (vi) in any other form of legal consideration that may be acceptable to the Board and
specified in the applicable Stock Award Agreement. 
 (d) Exercise and Payment of a SAR. To exercise any outstanding SAR, the
Participant must provide written notice of exercise to the Company in compliance with the provisions of the Stock Award Agreement evidencing such SAR. The appreciation distribution payable on the exercise of a SAR will be not greater than an amount
equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the SAR) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested under such SAR, and
with respect to which the Participant is exercising the SAR on such date, over (B) the aggregate strike price of the number of Common Stock equivalents with respect to which the Participant is exercising the SAR on such date. The appreciation
distribution may be paid in Common Stock, in cash, in any combination of the two or in any other form of consideration, as determined by the Board and contained in the Stock Award Agreement evidencing such SAR. 

(e) Transferability of Options and SARs. The Board may, in its sole discretion, impose such limitations on the transferability of
Options and SARs as the Board will determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and SARs will apply: 

(i) Restrictions on Transfer. An Option or SAR will not be transferable except by will or by the laws of descent and distribution (and
pursuant to subsections (ii) and (iii) below), and will be exercisable during the lifetime of the Participant only by the Participant. The Board may permit transfer of the Option or SAR in a manner that is not prohibited by applicable tax and
securities laws. Except as explicitly provided herein, neither an Option nor a SAR may be transferred for consideration. 
 (ii) Domestic
Relations Orders. Subject to the approval of the Board or a duly authorized Officer, an Option or SAR may be transferred pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation
instrument as permitted by Treasury Regulation 1.421-1(b)(2). If an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option as a result of such transfer. 

(iii) Beneficiary Designation. Subject to the approval of the Board or a duly authorized Officer, a Participant may, by delivering
written notice to the Company, in a form approved by the Company (or the designated broker), designate a third party who, upon the death of the Participant, will thereafter be entitled to exercise the Option or SAR and receive the Common Stock or
other consideration resulting from such exercise. In the absence of such a designation, upon the death of the Participant, the executor or administrator of the Participant’s estate will be entitled to exercise the Option or SAR and receive the
Common Stock or other consideration resulting from such exercise. However, the Company may prohibit designation of a beneficiary at any time, including due to any conclusion by the Company that such designation would be inconsistent with the
provisions of applicable laws. 

  
 7. 

 (f) Vesting Generally. The total number of shares of Common Stock subject to an
Option or SAR may vest and become exercisable in periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may not be exercised (which may be based on
the satisfaction of performance goals or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options or SARs may vary. The provisions of this Section 5(f) are subject to any Option or SAR provisions governing
the minimum number of shares of Common Stock as to which an Option or SAR may be exercised. 
 (g) Termination of Continuous Service.
Except as otherwise provided in the applicable Stock Award Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates (other than for Cause and other than upon the Participant’s
death or Disability), the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Stock Award as of the date of termination of Continuous Service) within the period of time ending on the
earlier of (i) the date three (3) months following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the applicable Stock Award Agreement, which period will not be less than
thirty (30) days if necessary to comply with applicable laws unless such termination is for Cause) and (ii) the expiration of the term of the Option or SAR as set forth in the Stock Award Agreement. If, after termination of Continuous
Service, the Participant does not exercise his or her Option or SAR within the applicable time frame, the Option or SAR (as applicable) will terminate. 

(h) Extension of Termination Date. Except as otherwise provided in the applicable Stock Award Agreement or other agreement
between the Participant and the Company, if the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause and other than upon the Participant’s death or Disability) would be
prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option or SAR will terminate on the earlier of (i) the expiration of a total period of
time (that need not be consecutive) equal to the applicable post termination exercise period after the termination of the Participant’s Continuous Service during which the exercise of the Option or SAR would not be in violation of such
registration requirements, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Stock Award Agreement. In addition, unless otherwise provided in a Participant’s Stock Award Agreement, if the sale of any
Common Stock received upon exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause) would violate the Company’s insider trading policy, then the Option or SAR will terminate on
the earlier of (i) the expiration of a period of time (that need not be consecutive) equal to the applicable post-termination exercise period after the termination of the Participant’s Continuous Service during which the sale of the Common
Stock received upon exercise of the Option or SAR would not be in violation of the Company’s insider trading policy, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Stock Award Agreement. 

  
 8. 

 (i) Disability of Participant. Except as otherwise provided in the applicable Stock
Award Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise his or her Option or SAR (to the extent
that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of (i) the date twelve (12) months following such
termination of Continuous Service (or such longer or shorter period specified in the Stock Award Agreement, which period will not be less than six (6) months if necessary to comply with applicable laws), and (ii) the expiration of the
term of the Option or SAR as set forth in the Stock Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the applicable time frame, the Option or SAR (as applicable) will
terminate. 
 (j) Death of Participant. Except as otherwise provided in the applicable Stock Award Agreement or other agreement
between the Participant and the Company, if (i) a Participant’s Continuous Service terminates as a result of the Participant’s death, or (ii) the Participant dies within the period (if any) specified in the Stock Award Agreement
for exercisability after the termination of the Participant’s Continuous Service (for a reason other than death), then the Option or SAR may be exercised (to the extent the Participant was entitled to exercise such Option or SAR as of the date
of death) by the Participant’s estate, by a person who acquired the right to exercise the Option or SAR by bequest or inheritance or by a person designated to exercise the Option or SAR upon the Participant’s death, but only within the
period ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the Stock Award Agreement, which period will not be less than six (6) months if
necessary to comply with applicable laws), and (ii) the expiration of the term of such Option or SAR as set forth in the Stock Award Agreement. If, after the Participant’s death, the Option or SAR is not exercised within the applicable
time frame, the Option or SAR (as applicable) will terminate. 
 (k) Termination for Cause. Except as explicitly provided
otherwise in a Participant’s Stock Award Agreement or other individual written agreement between the Company or any Affiliate and the Participant, if a Participant’s Continuous Service is terminated for Cause, the Option or SAR will
terminate immediately upon such Participant’s termination of Continuous Service, and the Participant will be prohibited from exercising his or her Option or SAR from and after the time of such termination of Continuous Service. 

(l) Non-Exempt Employees. If an Option or SAR is granted to an Employee who is a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, the Option or SAR will not be first exercisable for any shares of Common Stock until at least six (6) months following the
date of grant of the Option or SAR (although the Stock Award may vest prior to such date). Consistent with the provisions of the Worker Economic Opportunity Act, (i) if such non-exempt Employee dies or
suffers a Disability, (ii) upon a Corporate Transaction in which such Option or SAR is not assumed, continued, or substituted, (iii) upon a Change in Control, or (iv) upon the Participant’s retirement (as such term may be defined
in the Participant’s Stock Award Agreement, in another agreement between the Participant and the Company, or, if no such definition, in accordance with the Company’s then current employment policies and guidelines), the vested portion of
any Options and SARs may be exercised earlier 

  
 9. 

 
than six (6) months following the date of grant. The foregoing provision is intended to operate so that any income derived by a non-exempt employee in
connection with the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay. To the extent permitted and/or required for compliance with the Worker Economic Opportunity Act to ensure that any income derived by a non-exempt employee in connection with the exercise, vesting or issuance of any shares under any other Stock Award will be exempt from the employee’s regular rate of pay, the provisions of this
Section 5(l) will apply to all Stock Awards and are hereby incorporated by reference into such Stock Award Agreements. 
 (m) Early
Exercise of Options. An Option may, but need not, include a provision whereby the Optionholder may elect at any time before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the shares of
Common Stock subject to the Option prior to the full vesting of the Option. Subject to the “Repurchase Limitation” in Section 8(m), any unvested shares of Common Stock so purchased may be subject to a repurchase right in favor of
the Company or to any other restriction the Board determines to be appropriate. Provided that the “Repurchase Limitation” in Section 8(m) is not violated, the Company will not be required to exercise its repurchase right until at
least six (6) months (or such longer or shorter period of time required to avoid classification of the Option as a liability for financial accounting purposes) have elapsed following exercise of the Option unless the Board otherwise
specifically provides in the Option Agreement. 
 (n) Right of Repurchase. Subject to the “Repurchase Limitation” in
Section 8(m), the Option or SAR may include a provision whereby the Company may elect to repurchase all or any part of the vested shares of Common Stock acquired by the Participant pursuant to the exercise of the Option or SAR. 

(o) Right of First Refusal. The Option or SAR may include a provision whereby the Company may elect to exercise a right of first refusal
following receipt of notice from the Participant of the intent to transfer all or any part of the shares of Common Stock received upon the exercise of the Option or SAR. Such right of first refusal will be subject to the
“Repurchase Limitation” in Section 8(m). Except as expressly provided in this Section 5(o) or in the Stock Award Agreement, such right of first refusal will otherwise comply with any applicable provisions of the bylaws of
the Company. 
 6. PROVISIONS OF STOCK AWARDS OTHER THAN
OPTIONS AND SARS. 
 (a) Restricted Stock Awards. Each Restricted Stock Award
Agreement will be in such form and will contain such terms and conditions as the Board deems appropriate. To the extent consistent with the Company’s bylaws, at the Board’s election, shares of Common Stock underlying a Restricted Stock
Award may be (i) held in book entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (ii) evidenced by a certificate, which certificate will be held in such form and
manner as determined by the Board. The terms and conditions of Restricted Stock Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award Agreements need not be identical. Each Restricted Stock
Award Agreement will conform to (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 

  
 10. 

 (i) Consideration. A Restricted Stock Award may be awarded in consideration for
(A) cash, check, bank draft or money order payable to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of legal consideration (including future services) that may be acceptable to the Board,
in its sole discretion, and permissible under applicable law. 
 (ii) Vesting. Subject to the “Repurchase Limitation”
in Section 8(m), shares of Common Stock awarded under the Restricted Stock Award Agreement may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 

(iii) Termination of Participant’s Continuous Service. If a Participant’s Continuous Service terminates, the Company may
receive through a forfeiture condition or a repurchase right, any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination of Continuous Service under the terms of the Restricted Stock Award
Agreement. 
 (iv) Transferability. Rights to acquire shares of Common Stock under the Restricted Stock Award Agreement will be
transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board will determine in its sole discretion, so long as Common Stock awarded under the Restricted Stock Award
Agreement remains subject to the terms of the Restricted Stock Award Agreement. 
 (v) Dividends. A Restricted Stock Award Agreement
may provide that any dividends paid on Restricted Stock will be subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate. 

(b) Restricted Stock Unit Awards. Each Restricted Stock Unit Award Agreement will be in such form and will contain such terms and
conditions as the Board deems appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Unit Award Agreements need not be identical. Each
Restricted Stock Unit Award Agreement will conform to (through incorporation of the provisions hereof by reference in the Agreement or otherwise) the substance of each of the following provisions: 

(i) Consideration. At the time of grant of a Restricted Stock Unit Award, the Board will determine the consideration, if any, to
be paid by the Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant for each share of Common Stock subject to a Restricted Stock Unit Award may
be paid in any form of legal consideration that may be acceptable to the Board, in its sole discretion, and permissible under applicable law. 

(ii) Vesting. At the time of the grant of a Restricted Stock Unit Award, the Board may impose such restrictions on or conditions
to the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 
 (iii) Payment. A
Restricted Stock Unit Award may be settled by the delivery of shares of Common Stock, their cash equivalent, any combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award
Agreement. 

  
 11. 

 (iv) Additional Restrictions. At the time of the grant of a Restricted Stock
Unit Award, the Board, as it deems appropriate, may impose such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such
Restricted Stock Unit Award. 
 (v) Dividend Equivalents. Dividend equivalents may be credited in respect of shares of Common
Stock covered by a Restricted Stock Unit Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be converted into additional shares of Common
Stock covered by the Restricted Stock Unit Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all of the same terms and
conditions of the underlying Restricted Stock Unit Award Agreement to which they relate. 
 (vi) Termination of
Participant’s Continuous Service. Except as otherwise provided in the applicable Restricted Stock Unit Award Agreement, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the
Participant’s termination of Continuous Service.  
 (vii) Compliance with Section 409A of the Code.
Notwithstanding anything to the contrary set forth herein, any Restricted Stock Unit Award granted under the Plan that is not exempt from the requirements of Section 409A of the Code shall contain such provisions so that such Restricted Stock
Unit Award will comply with the requirements of Section 409A of the Code. Such restrictions, if any, shall be determined by the Board and contained in the Restricted Stock Unit Award Agreement evidencing such Restricted Stock Unit Award. For
example, such restrictions may include, without limitation, a requirement that any Common Stock that is to be issued in a year following the year in which the Restricted Stock Unit Award vests must be issued in accordance with a fixed pre-determined schedule. 
 (c) Other Stock Awards. Other forms of Stock Awards valued in
whole or in part by reference to, or otherwise based on, Common Stock, including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than one hundred percent (100%) of the Fair Market Value of
the Common Stock at the time of grant) may be granted either alone or in addition to Stock Awards provided for under Section 5 and the preceding provisions of this Section 6. Subject to the provisions of the Plan, the Board will have sole
and complete authority to determine the persons to whom and the time or times at which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to such Other Stock Awards
and all other terms and conditions of such Other Stock Awards. 

  
 12. 

 7. COVENANTS OF THE COMPANY. 

(a) Availability of Shares. The Company will keep available at all times the number of shares of Common Stock reasonably required to
satisfy then-outstanding Stock Awards. 
 (b) Securities Law Compliance. The Company will seek to obtain from each regulatory
commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided, however, that this undertaking will not
require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts and at a reasonable cost, the Company is unable to obtain from
any such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company will be relieved from any liability for failure to issue and sell Common
Stock upon exercise of such Stock Awards unless and until such authority is obtained. A Participant will not be eligible for the grant of a Stock Award or the subsequent issuance of cash or Common Stock pursuant to the Stock Award if such grant or
issuance would be in violation of any applicable securities law. 
 (c) No Obligation to Notify or Minimize Taxes. The Company will
have no duty or obligation to any Participant to advise such holder as to the time or manner of exercising such Stock Award. Furthermore, the Company will have no duty or obligation to warn or otherwise advise such holder of a pending termination or
expiration of a Stock Award or a possible period in which the Stock Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of a Stock Award to the holder of such Stock Award. 

8. MISCELLANEOUS. 
 (a)
Use of Proceeds from Sales of Common Stock. Proceeds from the sale of shares of Common Stock pursuant to Stock Awards will constitute general funds of the Company. 

(b) Corporate Action Constituting Grant of Stock Awards. Corporate action constituting a grant by the Company of a Stock Award to any
Participant will be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or letter evidencing the Stock Award is communicated to, or actually received or
accepted by, the Participant. In the event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the corporate action constituting the grant contain terms (e.g., exercise price, vesting schedule or number of shares)
that are inconsistent with those in the Stock Award Agreement as a result of a clerical error in the papering of the Stock Award Agreement, the corporate records will control and the Participant will have no legally binding right to the incorrect
term in the Stock Award Agreement. 
 (c) Stockholder Rights. No Participant will be deemed to be the holder of, or to have any of the
rights of a holder with respect to, any shares of Common Stock subject to a Stock Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of shares of Common Stock under, the Stock Award
pursuant to its terms, and (ii) the issuance of the Common Stock subject to the Stock Award has been entered into the books and records of the Company. 

  
 13. 

 (d) No Employment or Other Service Rights. Nothing in the Plan, any Stock Award
Agreement or any other instrument executed thereunder or in connection with any Stock Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time
the Stock Award was granted or will affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of
such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or
the Affiliate is incorporated, as the case may be. 
 (e) Change in Time Commitment. In the event a Participant’s regular level
of time commitment in the performance of his or her services for the Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a change in status from a
full-time Employee to a part-time Employee) after the date of grant of any Stock Award to the Participant, the Board has the right in its sole discretion to (x) make a corresponding reduction in the number of shares subject to any portion of
such Stock Award that is scheduled to vest or become payable after the date of such change in time commitment, and (y) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such Stock Award. In
the event of any such reduction, the Participant will have no right with respect to any portion of the Stock Award that is so reduced or extended. 

(f) Incentive Stock Option Limitations. To the extent that the aggregate Fair Market Value (determined at the time of grant) of Common
Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and any Affiliates) exceeds one hundred thousand dollars ($100,000) (or such
other limit established in the Code) or otherwise does not comply with the rules governing Incentive Stock Options, the Options or portions thereof that exceed such limit (according to the order in which they were granted) or otherwise do not comply
with such rules will be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s). 

(g) Investment Assurances. The Company may require a Participant, as a condition of exercising or acquiring Common Stock under any Stock
Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Stock Award; and (ii) to give written
assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account and not with any present intention of selling or otherwise distributing

  
 14. 

 
the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, will be inoperative if (A) the issuance of the shares upon the exercise or acquisition
of Common Stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act, or (B) as to any particular requirement, a determination is made by counsel for the Company that such
requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. 

(h) Withholding Obligations. Unless prohibited by the terms of a Stock Award Agreement, the Company may, in its sole discretion,
satisfy any federal, state or local tax withholding obligation relating to a Stock Award by any of the following means or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of
Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Stock Award; provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax
required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Stock Award as a liability for financial accounting purposes); (iii) withholding cash from a Stock Award settled in cash;
(iv) withholding payment from any amounts otherwise payable to the Participant; or (v) by such other method as may be set forth in the Stock Award Agreement. 

(i) Electronic Delivery. Any reference herein to a “written” agreement or document will include any agreement or document
delivered electronically or posted on the Company’s intranet (or other shared electronic medium controlled by the Company to which the Participant has access). 

(j) Deferrals. To the extent permitted by applicable law, the Board, in its sole discretion, may determine that the delivery of Common
Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Stock Award may be deferred and may establish programs and procedures for deferral elections to be made by Participants. Deferrals by Participants will
be made in accordance with Section 409A of the Code. Consistent with Section 409A of the Code, the Board may provide for distributions while a Participant is still an employee or otherwise providing services to the Company. The Board is
authorized to make deferrals of Stock Awards and determine when, and in what annual percentages, Participants may receive payments, including lump sum payments, following the Participant’s termination of Continuous Service, and implement such
other terms and conditions consistent with the provisions of the Plan and in accordance with applicable law. 
 (k) Compliance with
Section 409A of the Code. To the extent that the Board determines that any Stock Award granted hereunder is subject to Section 409A of the Code, the Stock Award Agreement evidencing such Stock Award shall incorporate the
terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code. To the extent applicable, the Plan and Stock Award Agreements shall be interpreted in accordance with Section 409A of the Code. 

  
 15. 

 (l) Compliance with Exemption Provided by Rule
12h-1(f). If at the end of the Company’s most recently completed fiscal year: (i) the aggregate of the number of persons who hold outstanding compensatory employee stock options to purchase
shares of Common Stock granted pursuant to the Plan or otherwise (such persons, “Holders of Options”) equals or exceeds five hundred (500), and (ii) the Company’s assets exceed $10 million, then the following
restrictions will apply during any period during which the Company does not have a class of its securities registered under Section 12 of the Exchange Act and is not required to file reports under Section 15(d) of the Exchange Act:
(A) the Options and, prior to exercise, the shares of Common Stock to be issued on exercise of the Options may not be transferred until the Company is no longer relying on the exemption provided by Rule
12h-1(f) promulgated under the Exchange Act (“Rule 12h-1(f)”), except: (1) as permitted by Rule 701(c) promulgated under the
Securities Act, (2) to a guardian upon the disability of the Holder of Options, or (3) to an executor upon the death of the Holder of Options (collectively, the “Permitted Transferees”); provided, however, the
following transfers are permitted: (i) transfers by Holders of Options to the Company, and (ii) transfers in connection with a change of control or other acquisition involving the Company, if following such transaction, the Options no
longer remain outstanding and the Company is no longer relying on the exemption provided by Rule 12h-1(f); provided further, that any Permitted Transferees may not further transfer the Options; (B) except
as otherwise provided in (A) above, the Options and shares of Common Stock issuable on exercise of the Options are restricted as to any pledge, hypothecation, or other transfer, including any short position, any “put equivalent
position” as defined by Rule 16a-1(h) promulgated under the Exchange Act, or any “call equivalent position” as defined by Rule 16a-1(b) promulgated under
the Exchange Act by Holders of Options prior to exercise of an Option until the Company is no longer relying on the exemption provided by Rule 12h-1(f); and (C) at any time that the Company is relying on
the exemption provided by Rule 12h-1(f), the Company will deliver to Holders of Options (whether by physical or electronic delivery or written notice of the availability of the information on an internet site)
the information required by Rule 701(e)(3), (4), and (5) promulgated under the Securities Act every six (6) months, including financial statements that are not more than one hundred eighty (180) days old; provided, however, that the
Company may condition the delivery of such information upon the Holder of Options’ agreement to maintain its confidentiality. 
 (m)
Repurchase Limitation. The terms of any repurchase right will be specified in the Stock Award Agreement. The repurchase price for vested shares of Common Stock will be the Fair Market Value of the shares of Common Stock on the date of
repurchase. The repurchase price for unvested shares of Common Stock will be the lower of (i) the Fair Market Value of the shares of Common Stock on the date of repurchase or (ii) their original purchase price. However, the Company will
not exercise its repurchase right until at least six (6) months (or such longer or shorter period of time necessary to avoid classification of the Stock Award as a liability for financial accounting purposes) have elapsed following
delivery of shares of Common Stock subject to the Stock Award, unless otherwise specifically provided by the Board. 
 9. ADJUSTMENTS
UPON CHANGES IN COMMON STOCK; OTHER CORPORATE EVENTS. 

(a) Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board will appropriately and proportionately adjust:
(i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities that may be issued pursuant to the exercise of Incentive Stock Options pursuant to
Section 3(c), and (iii) the class(es) and number of securities and price per share of stock subject to outstanding Stock Awards. The Board will make such adjustments, and its determination will be final, binding and conclusive. 

  
 16. 

 (b) Dissolution or Liquidation. Except as otherwise provided in the Stock Award
Agreement, in the event of a dissolution or liquidation of the Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s
right of repurchase) will terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be repurchased or
reacquired by the Company notwithstanding the fact that the holder of such Stock Award is providing Continuous Service, provided, however, that the Board may, in its sole discretion, cause some or all Stock Awards to become fully vested,
exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Stock Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion. 

(c) Corporate Transaction. The following provisions will apply to Stock Awards in the event of a Corporate Transaction unless otherwise
provided in the Stock Award Agreement or any other written agreement between the Company or any Affiliate and the Participant or unless otherwise expressly provided by the Board at the time of grant of a Stock Award. In the event of a Corporate
Transaction, then, notwithstanding any other provision of the Plan, the Board may take one or more of the following actions with respect to Stock Awards, contingent upon the closing or completion of the Corporate Transaction: 

(i) arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to
assume or continue the Stock Award or to substitute a similar stock award for the Stock Award (including, but not limited to, an award to acquire the same consideration paid to the stockholders of the Company pursuant to the Corporate Transaction);

 (ii) arrange for the assignment of any reacquisition or repurchase rights held by the Company in respect of Common Stock issued
pursuant to the Stock Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company); 

(iii) accelerate the vesting, in whole or in part, of the Stock Award (and, if applicable, the time at which the Stock Award may be
exercised) to a date prior to the effective time of such Corporate Transaction as the Board determines (or, if the Board does not determine such a date, to the date that is five (5) days prior to the effective date of the Corporate
Transaction), with such Stock Award terminating if not exercised (if applicable) at or prior to the effective time of the Corporate Transaction; provided, however, that the Board may require Participants to complete and deliver to the Company a
notice of exercise before the effective date of a Corporate Transaction, which exercise is contingent upon the effectiveness of such Corporate Transaction; 

  
 17. 

 (iv) arrange for the lapse, in whole or in part, of any reacquisition or repurchase
rights held by the Company with respect to the Stock Award; 
 (v) cancel or arrange for the cancellation of the Stock Award, to the
extent not vested or not exercised prior to the effective time of the Corporate Transaction, in exchange for such cash consideration, if any, as the Board, in its sole discretion, may consider appropriate; and 

(vi) make a payment, in such form as may be determined by the Board equal to the excess, if any, of (A) the value of the property
the Participant would have received upon the exercise of the Stock Award immediately prior to the effective time of the Corporate Transaction, over (B) any exercise price payable by such holder in connection with such exercise. For clarity,
this payment may be zero ($0) if the value of the property is equal to or less than the exercise price. Payments under this provision may be delayed to the same extent that payment of consideration to the holders of the Company’s Common Stock
in connection with the Corporate Transaction is delayed as a result of escrows, earn outs, holdbacks or any other contingencies. 
 The Board need not take
the same action or actions with respect to all Stock Awards or portions thereof or with respect to all Participants. The Board may take different actions with respect to the vested and unvested portions of a Stock Award.  

(d) Change in Control. A Stock Award may be subject to additional acceleration of vesting and exercisability upon or after a Change in
Control as may be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such acceleration
will occur. 
 10. PLAN TERM; EARLIER TERMINATION OR SUSPENSION
OF THE PLAN. 
 (a) Plan Term. The Board may suspend or terminate the Plan at any
time. Unless terminated sooner by the Board, the Plan will automatically terminate on the day before the tenth (10th) anniversary of the earlier of (i) the date the Plan is adopted by the Board, or (ii) the date the Plan is approved
by the stockholders of the Company. No Stock Awards may be granted under the Plan while the Plan is suspended or after it is terminated. 

(b) No Impairment of Rights. Suspension or termination of the Plan will not impair rights and obligations under any Stock Award granted
while the Plan is in effect except with the written consent of the affected Participant or as otherwise permitted in the Plan. 
 11.
EFFECTIVE DATE OF PLAN. 
 This Plan will become effective on the Effective
Date.

apply to the capitalized terms indicated below: 
 (a) “Affiliate” means, at the time of determination, any

subsidiary” status is determined within the foregoing definition. 
 (b) “Board” means the Board of
Directors of the Company. 
 (c) “Capitalization Adjustment” means any change that is made in, or other events

reincorporation, stock dividend, dividend in property other than cash, large nonrecurring cash dividend, stock split, reverse stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure, or any similar
equity restructuring transaction, as that term is used in Statement of Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto). Notwithstanding the foregoing, the conversion of any convertible
securities of the Company will not be treated as a Capitalization Adjustment. 
 (d) “Cause”
will have the meaning ascribed to such term in any written agreement between the Participant and the Company defining such term and, in the absence of such agreement, such term means, with respect to a Participant, the occurrence of any of
the following events: (i) such Participant’s commission of any felony or any crime involving fraud, dishonesty or moral turpitude under the laws of the United States or any state thereof; (ii) such Participant’s attempted
commission of, or participation in, a fraud or act of dishonesty against the Company; (iii) such Participant’s intentional, material violation of any contract or agreement between the Participant and the Company or of any statutory duty
owed to the Company; (iv) such Participant’s unauthorized use or disclosure of the Company’s confidential information or trade secrets; or (v) such Participant’s gross misconduct. The determination that a termination of the
Participant’s Continuous Service is either for Cause or without Cause will be made by the Company, in its sole discretion. Any determination by the Company that the Continuous Service of a Participant was terminated with or without Cause for
the purposes of outstanding Stock Awards held by such Participant will have no effect upon any determination of the rights or obligations of the Company or such Participant for any other purpose. 

(e) “Change in Control” means the occurrence, in a single transaction or in a series of related transactions,
of any one or more of the following events: 
 (i) any Exchange Act Person becomes the Owner, directly or indirectly, of securities
of the Company representing more than fifty percent (50%) of the combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the foregoing,
a Change in Control will not be deemed to occur (A) on account of the acquisition of securities of the Company directly from the Company, (B) on account of the acquisition of securities of the Company by an investor, any affiliate thereof

  
 19. 

 
or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company
through the issuance of equity securities or (C) solely because the level of Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold
of the outstanding voting securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this
sentence) as a result of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not
occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control will be deemed to occur;  

(ii) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and, immediately
after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing more than
fifty percent (50%) of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than fifty percent (50%) of the combined outstanding voting power of the
parent of the surviving Entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction;

 (iii) the stockholders of the Company approve or the Board approves a plan of complete dissolution or liquidation of the Company,
or a complete dissolution or liquidation of the Company will otherwise occur, except for a liquidation into a parent corporation; or 

(iv) there is consummated a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets
of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries to an Entity, more than fifty percent (50%) of the
combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such sale, lease,
license or other disposition. 
 Notwithstanding the foregoing definition or any other provision of this Plan, (A) the term Change in Control will not
include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, and (B) the definition of Change in Control (or any analogous term) in an individual written agreement between
the Company or any Affiliate and the Participant will supersede the foregoing definition with respect to Stock Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is set forth
in such an individual written agreement, the foregoing definition will apply. 
 (f) “Code” means the Internal
Revenue Code of 1986, as amended, including any applicable regulations and guidance thereunder.

(k) “Continuous Service” means that the Participant’s service with the Company or an Affiliate, whether as
an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate as an Employee, Director or Consultant or a change in the Entity for which the
Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, will not terminate a Participant’s Continuous Service; provided, however, that if
the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board in its sole discretion, such Participant’s Continuous Service will be considered to have terminated on the date such Entity
ceases to qualify as an Affiliate. For example, a change in status from an Employee of the Company to a Consultant of an Affiliate or to a Director will not constitute an interruption of Continuous Service. To the extent permitted by law, the Board
or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service will be considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive
officer, including sick leave, military leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, a leave of absence will be treated as Continuous Service for
purposes of vesting in a Stock Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms of any leave of absence agreement or policy applicable to the Participant, or as otherwise required by
law. 
 (l) “Corporate Transaction” means the consummation, in a single transaction or in a series of related

the Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and are deemed to constitute “restricted securities” under Rule 701 and Rule 144 promulgated under the
Securities Act. I warrant and represent to the Company that I have no present intention of distributing or selling said Shares, except as permitted under the Securities Act and any applicable state securities laws. 

I further acknowledge that I will not be able to resell the Shares for at least ninety (90) days after the stock of the Company becomes
publicly traded (i.e., subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934) under Rule 701 and that more restrictive conditions apply to affiliates of the Company under Rule 144. 

I further acknowledge that all certificates representing any of the Shares subject to the provisions of the Option shall have endorsed thereon
appropriate legends reflecting the foregoing limitations, as well as any legends reflecting restrictions pursuant to the Company’s Articles of Incorporation, Bylaws and/or applicable securities laws. 

I further agree that, if required by the Company (or a representative of the underwriters) in connection with the first underwritten
registration of the offering of any securities of the Company under the Securities Act, I will not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the
same economic effect as a sale with respect to any shares of Common Stock or other securities of the Company for a period of one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the
Securities Act (or such longer period as the underwriters or the Company shall request to facilitate compliance with FINRA Rule 2711 or NYSE Member Rule 472 or any successor or similar rule or regulation) (the “Lock-Up Period”). I further agree to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriters that are consistent with the foregoing or that are
necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until
the end of such period. 
  

			
	Very truly yours,

 SONIM TECHNOLOGIES, INC. 

2012 EQUITY INCENTIVE PLAN 

OPTION AGREEMENT 

(INCENTIVE STOCK OPTION OR NONSTATUTORY STOCK
OPTION) 
 Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Option Agreement,
Sonim Technologies, Inc. (the “Company”) has granted you an option under its 2012 Equity Incentive Plan (the “Plan”) to purchase the number of shares of the Company’s Common Stock indicated in
your Grant Notice at the exercise price indicated in your Grant Notice. The option is granted to you effective as of the date of grant set forth in the Grant Notice (the “Date of Grant”). If there is any conflict between the
terms in this Option Agreement and the Plan, the terms of the Plan will control. Capitalized terms not explicitly defined in this Option Agreement or in the Grant Notice but defined in the Plan will have the same definitions as in the Plan. 

The details of your option, in addition to those set forth in the Grant Notice and the Plan, are as follows: 

1. VESTING. Your option will vest as provided in your Grant Notice. Vesting will cease upon the termination of
your Continuous Service. 
 2. NUMBER OF SHARES AND
EXERCISE PRICE. The number of shares of Common Stock subject to your option and your exercise price per share in your Grant Notice will be adjusted for Capitalization Adjustments. 

3. EXERCISE RESTRICTION FOR
NON-EXEMPT EMPLOYEES. If you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (that is, a “Non-Exempt Employee”), and except as otherwise provided in the Plan, you may not exercise your option until you have completed at least six (6) months of Continuous Service measured from the Date
of Grant, even if you have already been an employee for more than six (6) months. Consistent with the provisions of the Worker Economic Opportunity Act, you may exercise your option as to any vested portion prior to such six (6) month
anniversary in the case of (i) your death or disability, (ii) a Corporate Transaction in which your option is not assumed, continued or substituted, (iii) a Change in Control or (iv) your termination of Continuous Service on your
“retirement” (as defined in the Company’s benefit plans). 
 4. EXERCISE PRIOR
TO VESTING (“EARLY EXERCISE”). If permitted in your Grant Notice (i.e., the “Exercise Schedule” indicates “Early Exercise Permitted”) and subject to
the provisions of your option, you may elect at any time that is both (i) during the period of your Continuous Service and (ii) during the term of your option, to exercise all or part of your option, including the unvested portion of your
option; provided, however, that: 
 (a) a partial exercise of your option will be deemed to cover first vested shares of Common
Stock and then the earliest vesting installment of unvested shares of Common Stock; 

  
 1. 

 (b) any shares of Common Stock so purchased from installments that have not vested as
of the date of exercise will be subject to the purchase option in favor of the Company as described in the Company’s form of Early Exercise Stock Purchase Agreement; 

(c) you will enter into the Company’s form of Early Exercise Stock Purchase Agreement with a vesting schedule that will result in
the same vesting as if no early exercise had occurred; and 
 (d) if your option is an Incentive Stock Option, then, to the extent
that the aggregate Fair Market Value (determined at the Date of Grant) of the shares of Common Stock with respect to which your option plus all other Incentive Stock Options you hold are exercisable for the first time by you during any calendar year
(under all plans of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000), your option(s) or portions thereof that exceed such limit (according to the order in which they were granted) will be treated as Nonstatutory Stock
Options. 
 5. METHOD OF PAYMENT. You must pay the full amount of the exercise
price for the shares you wish to exercise. You may pay the exercise price in cash or by check, bank draft or money order payable to the Company or in any other manner permitted by your Grant Notice, which may include one or more of the
following: 
 (a) Provided that at the time of exercise the Common Stock is publicly traded, pursuant to a program developed under
Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to
the Company from the sales proceeds. This manner of payment is also known as a “broker-assisted exercise”, “same day sale”, or “sell to cover”. 

(b) Provided that at the time of exercise the Common Stock is publicly traded, by delivery to the Company (either by actual delivery or
attestation) of already-owned shares of Common Stock that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date of exercise. “Delivery” for these purposes,
in the sole discretion of the Company at the time you exercise your option, will include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by the Company. You may not exercise your option by
delivery to the Company of Common Stock if doing so would violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. 

6. WHOLE SHARES. You may exercise your option only for whole shares of Common Stock. 

7. SECURITIES LAW COMPLIANCE. In no event may you exercise your option unless the
shares of Common Stock issuable upon exercise are then registered under the Securities Act or, if not registered, the Company has determined that your exercise and the issuance of the shares would be exempt from the registration requirements of the
Securities Act. The exercise of your option also must comply with all other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would not be in material compliance
with such laws and regulations (including any restrictions on exercise required for compliance with Treas. Reg. 1.401(k)-1(d)(3), if applicable). 

  
 2. 

 8. TERM. You may not exercise your option before the Date of
Grant or after the expiration of the option’s term. The term of your option expires, subject to the provisions of Section 5(h) of the Plan, upon the earliest of the following: 

(a) immediately upon the termination of your Continuous Service for Cause; 

(b) three (3) months after the termination of your Continuous Service for any reason other than Cause, your Disability or
your death (except as otherwise provided in Section 8(d) below); provided, however, that if during any part of such three (3) month period your option is not exercisable solely because of the condition set forth in the section above
relating to “Securities Law Compliance,” your option will not expire until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of three (3) months after the termination of your Continuous
Service; provided further, [if during any part of such three (3) month period, the sale of any Common Stock received upon exercise of your option would violate the Company’s insider trading policy, then your option will not expire
until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service during which the sale of the Common Stock received upon exercise of your
option would not be in violation of the Company’s insider trading policy; 
 (c) twelve (12) months after the termination of
your Continuous Service due to your Disability (except as otherwise provided in Section 8(d)) below; 
 (d) eighteen
(18) months after your death if you die either during your Continuous Service or within three (3) months after your Continuous Service terminates for any reason other than Cause; 

(e) the Expiration Date indicated in your Grant Notice; or 

(f) the day before the tenth (10th) anniversary of the Date of Grant. 

If your option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock Option,
the Code requires that at all times beginning on the Date of Grant and ending on the day three (3) months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in the event of your death
or your Disability. The Company has provided for extended exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you continue to
provide services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment with the Company or an Affiliate
terminates. 

  
 3. 

 9. EXERCISE. 

(a) You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during
its term by (i) delivering a Notice of Exercise (in a form designated by the Company) or completing such other documents and/or procedures designated by the Company for exercise and (ii) paying the exercise price and any applicable
withholding taxes to the Company’s Secretary, stock plan administrator, or such other person as the Company may designate, together with such additional documents as the Company may then require. 

(b) By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter into
an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (i) the exercise of your option, (ii) the lapse of any substantial risk of forfeiture to which the shares
of Common Stock are subject at the time of exercise, or (iii) the disposition of shares of Common Stock acquired upon such exercise. 

(c) If your option is an Incentive Stock Option, by exercising your option you agree that you will notify the Company in writing within
fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the Date of Grant or within one (1) year after such shares of
Common Stock are transferred upon exercise of your option. 
 (d) By exercising your option you agree that you will not sell, dispose
of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale with respect to any shares of Common Stock or other securities of the Company held
by you, for a period of one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act or such longer period as the underwriters or the Company will request to facilitate
compliance with FINRA Rule 2711 or NYSE Member Rule 472 or any successor or similar rules or regulation (the “Lock-Up Period”); provided, however, that nothing contained in this
section will prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-Up Period. You further agree to execute and deliver such other agreements as may be reasonably
requested by the Company or the underwriters that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to
your shares of Common Stock until the end of such period. You also agree that any transferee of any shares of Common Stock (or other securities) of the Company held by you will be bound by this Section 9(d). The underwriters of the
Company’s stock are intended third party beneficiaries of this Section 9(d) and will have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 

10. TRANSFERABILITY. Except as otherwise provided in this Section 10, your option is not transferable, except
by will or by the laws of descent and distribution, and is exercisable during your life only by you. 
 (a) Certain Trusts.
Upon receiving written permission from the Board or its duly authorized designee, you may transfer your option to a trust if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law)
while the option is held in the trust. You and the trustee must enter into transfer and other agreements required by the Company. 

  
 4. 

 (b) Domestic Relations Orders. Upon receiving written permission from the
Board or its duly authorized designee, and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your option pursuant to the terms of a domestic relations order, official
marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulation 1.421-1(b)(2) that contains the information required by the Company to effectuate the transfer. You
are encouraged to discuss the proposed terms of any division of this option with the Company prior to finalizing the domestic relations order or marital settlement agreement to help ensure the required information is contained within the domestic
relations order or marital settlement agreement. If this option is an Incentive Stock Option, this option may be deemed to be a Nonstatutory Stock Option as a result of such transfer. 

(c) Beneficiary Designation. Upon receiving written permission from the Board or its duly authorized designee, you may, by
delivering written notice to the Company, in a form approved by the Company and any broker designated by the Company to handle option exercises, designate a third party who, on your death, will thereafter be entitled to exercise this option and
receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, your executor or administrator of your estate will be entitled to exercise this option and receive, on behalf of your estate, the
Common Stock or other consideration resulting from such exercise. 
 11. RIGHT OF
FIRST REFUSAL. Shares of Common Stock that you acquire upon exercise of your option are subject to any right of first refusal that may be described in the Company’s bylaws in effect at such time the Company
elects to exercise its right. The Company’s right of first refusal will expire on the first date upon which any security of the Company is listed (or approved for listing) upon notice of issuance on a national securities exchange or quotation
system. 
 12. RIGHT OF REPURCHASE. To the extent provided in the Company’s
bylaws in effect at such time the Company elects to exercise its right, the Company will have the right to repurchase all or any part of the shares of Common Stock you acquire pursuant to the exercise of your option. 

13. OPTION NOT A SERVICE CONTRACT. Your option is not
an employment or service contract, and nothing in your option will be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your
employment. In addition, nothing in your option will obligate the Company or an Affiliate, their respective stockholders, boards of directors, officers or employees to continue any relationship that you might have as a Director or Consultant for the
Company or an Affiliate. 
 14. WITHHOLDING OBLIGATIONS. 

(a) At the time you exercise your option, in whole or in part, and at any time thereafter as requested by the Company, you hereby
authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “same day sale” pursuant to a program developed under Regulation T as promulgated by the
Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise of your
option. 

  
 5. 

 (b) If this option is a Nonstatutory Stock Option, then upon your request and subject
to approval by the Company, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of
Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of your option
as a liability for financial accounting purposes). If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your option, share withholding pursuant to the preceding sentence shall not be
permitted unless you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise deferred, to
accelerate the determination of such tax withholding obligation to the date of exercise of your option. Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined
as of the date of exercise of your option that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. 

(c) You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied.
Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company will have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any
escrow provided for herein, if applicable, unless such obligations are satisfied. 
 15. TAX
CONSEQUENCES. You hereby agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You will not make any claim
against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the
Code only if the exercise price per share specified in the Grant Notice is at least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated
with the option. Because the Common Stock is not traded on an established securities market, the Fair Market Value is determined by the Board, perhaps in consultation with an independent valuation firm retained by the Company. You acknowledge that
there is no guarantee that the Internal Revenue Service will agree with the valuation as determined by the Board, and you will not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates in the event that the
Internal Revenue Service asserts that the valuation determined by the Board is less than the “fair market value” as subsequently determined by the Internal Revenue Service. 

16. NOTICES. Any notices provided for in your option or the Plan will be given in writing (including
electronically) and will be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address
you provided to the Company. 

  
 6. 

 
The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this option by electronic means or to request your consent to participate in the
Plan by electronic means. By accepting this option, you consent to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and
maintained by the Company or another third party designated by the Company. 
 17. GOVERNING PLAN
DOCUMENT. Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations, which may from
time to time be promulgated and adopted pursuant to the Plan. If there is any conflict between the provisions of your option and those of the Plan, the provisions of the Plan will control. 

18. EFFECT ON OTHER EMPLOYEE BENEFIT
PLANS. The value of this option will not be included as compensation, earnings, salaries, or other similar terms used when calculating your benefits under any employee benefit plan sponsored by the Company or any
Affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Affiliate’s employee benefit plans. 

19. VOTING RIGHTS. You will not have voting or any other rights as a stockholder of
the Company with respect to the shares to be issued pursuant to this option until such shares are issued to you. Upon such issuance, you will obtain full voting and other rights as a stockholder of the Company. Nothing contained in this option, and
no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person. 

20. SEVERABILITY. If all or any part of this Option Agreement or the Plan is declared by any court
or governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Option Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Option Agreement (or part of such a
Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

21. MISCELLANEOUS. 

(a) The rights and obligations of the Company under your option will be transferable to any one or more persons or entities, and all
covenants and agreements hereunder will inure to the benefit of, and be enforceable by the Company’s successors and assigns. 
 (b)
You agree upon request to execute any further documents or instruments necessary or desirable in the sole determination of the Company to carry out the purposes or intent of your option. 

(c) You acknowledge and agree that you have reviewed your option in its entirety, have had an opportunity to obtain the advice of
counsel prior to executing and accepting your option, and fully understand all provisions of your option. 

  
 7. 

 (d) This Option Agreement will be subject to all applicable laws, rules, and
regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. 
 (e) All
obligations of the Company under the Plan and this Option Agreement will be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all
or substantially all of the business and/or assets of the Company. 
 * * * 

This Option Agreement will be deemed to be signed by you upon the signing by you of the Stock Option Grant Notice to which it is attached.
