 2. Information Rights.

as-converted to common stock basis, as adjusted for recapitalizations, stock combinations, stock dividends, stock splits and the like) (a “Major Purchaser”), the Company will provide to such Major Purchasers the following
information: 
 (a) as soon as practicable, but in any event within ninety (90) days after the end of each fiscal year of
the Company, a balance sheet, statements of operations and cash flow for such fiscal year and an operating budget for the next fiscal year. The year-end financial reports shall be in reasonable detail, shall be prepared in accordance with generally
accepted accounting principles (“GAAP”), and shall be audited and certified by independent public accountants of national standing selected by the Company; 
 (b) as soon as practicable, but in any event thirty (30) days prior to the end of each fiscal year, a budget and any business plan for
the next fiscal year, prepared on a monthly basis; 
 (c) within forty-five (45) days after the end of each of the first
three (3) quarters of each fiscal year, an unaudited statement of operations, cash flows and balance sheet for and as of the end of such quarter, in reasonable detail and prepared in accordance with GAAP (but excluding financial statement
footnotes otherwise required by GAAP), subject to year end audit adjustments; and 
 (d) with respect to the financial
statements called for in subsections (b) and (c) of this Section 2.1, an instrument executed by the Chief Financial Officer or President of the Company certifying that such financials were prepared in accordance with GAAP (with the
exception that such financial statements do not include footnotes otherwise required by GAAP) consistently applied with prior periods and fairly present the financial condition of the Company and its results of operations for the period specified,
subject to year-end audit adjustments. 
 2.2 Inspection. The Company shall permit each Major Purchaser, at such
individual’s expense, to visit and inspect the Company’s properties, examine its books and records and to discuss the Company’s affairs, finances and accounts with its officers, at all such reasonable times as may be requested by such
individual; provided, however, that the Company shall not be required to comply with this Section 2.2 in respect to any Major Purchaser whom the Company reasonably determines to be a competitor of the Company, or an officer,
employee, director or stockholder of such competitor; provided, further, that the Company shall not be obligated pursuant to this Section 2.2 to provide access to any information that it reasonably

  

 4 

 
considers to be a trade secret or similar confidential information. For purposes of this Section 2.2 and Section 2.4, below only, neither Motorola, Inc. nor its affiliates shall be
deemed to be a competitor of the Company, unless a majority of the Board of Directors of the Company (the “Board”) reasonably determines in good faith, based on acquisition, new product development, or similar event that
occurs after the effective date of this Agreement (other than an event pursuant to agreements or arrangements between the Company and Motorola), that Motorola or its affiliates has become a direct competitor of the Company with respect to a material
portion of the Company’s business. 
 2.3 Assignment of Rights to Financial Information. The rights to receive
information pursuant to Sections 2.1 and 2.2 may be assigned or otherwise conveyed by any Major Purchaser or subsequent transferee of shares of Preferred Stock or Conversion Stock only to an affiliate or to a transferee who acquires at least 12,800
shares of Preferred Stock, Conversion Stock or a combination thereof (each, on an as-converted to common stock basis, as adjusted for recapitalizations, stock combinations, stock dividends, stock splits and the like); provided,
however, that the transferee of such rights is not deemed by a majority of the Board, in its reasonable judgment and sole discretion, to be a direct competitor of the Company. Upon request of a Major Purchaser, the Board will promptly (in no
event later than five (5) business days after such request) inform such Major Purchaser if it deems a potential assignee to be a competitor of the Company. 
 2.4 Confidential Information. Each Purchaser and any successor or assign of such Purchaser who receives from the Company or its agents, directly or indirectly, any information that the Company has
not made generally available to the public, pursuant to the preparation and execution of this Agreement or disclosure in connection therewith or pursuant to the provisions of this Section 2, acknowledges and agrees that such information is
confidential and for its use only in connection with evaluating its investment in the Company, and further agrees that it will not use or disseminate such information to any person other than its accountant, investment advisor, general or limited
partners, members of limited liability companies controlled by them or attorney and that such dissemination shall be only for purposes of evaluating its investment. The Company shall not be required to comply with any provision of Sections 2.1(c),
or 2.2 in respect to any Purchaser (subject to the last sentence of Section 2.2) whom a majority of the Board reasonably determines to be a direct competitor of the Company, or an officer, employee, director or stockholder of such competitor.

 2.5 Termination of Covenants. The rights set forth in Sections 2.1 and 2.2 shall terminate and be of no further force
or effect upon the earlier of (a) the closing of the Initial Public Offering, or on the date the Company otherwise becomes subject to the reporting requirements under Section 13 or 15(d) of the Exchange Act, or (b) the closing of a
Change of Control Transaction. 
 3. Registration Rights. 
 3.1 Requested Registration. 
 (a) If at any time after the earlier of (i) three (3) years after the date of the Agreement or (ii) one (1) year after the consummation of the Initial Public Offering, the Company
shall receive a written request from Initiating Holders that the Company effect any registration with respect to shares of Registrable Securities, the Company will: 
 (i) promptly give written notice of the proposed registration to all other Holders; and 
  

 5 

 (ii) as soon as practicable, use commercially reasonable efforts to effect such
registration as part of a firm commitment underwritten public offering (including, without limitation, appropriate qualification under applicable state securities laws and appropriate compliance with applicable regulations issued under the
Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request by delivering a written notice to such effect to the Company within twenty (20) days after the date of delivery of such written
notice by the Company pursuant to subsection (i) above. 
 Notwithstanding the foregoing, the Company shall not be obligated to take any
action to effect or complete any such registration pursuant to this Section 3.1: 
 (A) if the Registrable
Securities proposed to be registered may be registered immediately on Form S-3 pursuant to Section 3.3 below; 
 (B) unless the requested registration would have an aggregate offering price of all Registrable Securities sought to be registered by all Holders, net of underwriting discounts and commissions, exceeding $10,000,000; 
 (C) during the period that begins sixty (60) days before the Company’s good faith estimate of the filing of, and
that ends one hundred eighty (180) days immediately following the effective date of, any registration statement pertaining to any securities of the Company (other than a registration of securities in a Rule 145 transaction or with respect to an
employee benefit plan); provided, however, that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective; 
 (D) after the Company has effected two (2) registrations pursuant to this Section 3.1(a) and such registrations
have been declared or ordered effective; 
 (E) within twelve (12) months after the Company has effected
such a registration pursuant to this Section 3.1(a), and such registration has been declared or ordered effective; or 
 (F) if the Company furnishes to the Initiating Holders a certificate signed by the President or Chief Executive Officer of the Company (i) giving notice of its bona fide intention to effect within
sixty (60) days, the filing of a registration statement (other than a registration of securities pursuant to Form S-4 or Form S-8 or otherwise with respect to an employee benefit plan) (provided that the Company is actively employing in good
faith all reasonable efforts to cause such registration statement to become effective) including for the Company’s first registered public offering of its Common Stock with the Commission whereupon such requested registration shall be
accomplished pursuant to Section 3.2 hereof, or (ii) stating that in the good faith judgment of the Board it would be seriously detrimental to the Company or its

  

 6 

 
stockholders for a registration statement to be filed in the near future and that it is, therefore, essential to defer the filing of such registration statement. In such case, the Company’s
obligation to use its commercially reasonable efforts to register, qualify or comply under this Section 3.1(a) shall be deferred one or more times each for a period not to exceed 180 days from the receipt of the request to file such
registration by such Initiating Holder or Holders, provided that the Company may not exercise this deferral right more than once per twelve-month period. 
 Subject to the foregoing clauses (A) through (F), the Company shall file a registration statement covering the Registrable Securities so requested to be registered as soon as practicable after
receipt of the request or requests of the Initiating Holders. 
 (b) Underwriting. In the event of a registration
pursuant to Section 3.1, the Company shall advise the Holders as part of the notice given pursuant to Section 3.1(a)(i) that the right of any Holder to participate in such registration pursuant to Section 3.1 shall be conditioned upon
such Holder’s participation in the underwriting arrangements required by this Section 3.1, and the inclusion of such Holder’s Registrable Securities in the underwriting, subject to the limitations set forth below. The Company shall,
together with all Holders proposing to distribute their securities through such underwriting, enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by a majority of the Initiating Holders
and reasonably acceptable to the Company. Notwithstanding any other provision of this Section 3.1, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing
underwriter may limit the Registrable Securities to be included in such registration and the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated in the following priority:

 (i) first, among all Holders of Registrable Securities (pro rata among such selling Holders on the basis of the respective
amounts of Registrable Securities held by all such selling Holders); provided, however, the aggregate number of Registrable Securities that may be included in such registration may be limited by such managing underwriter; (A) in
the case of the Initial Public Offering, only to an amount no less than thirty-three percent (33%) of the total number of shares included in such registration and pro rata among Holders of Registrable Securities on the basis of Registrable
Securities held by all such Holders, and (B) in the case of any other offering, only to an amount no less than sixty-six percent (66%) of the total number of shares included in such registration and pro rata among Holders of Registrable
Securities on the basis of Registrable Securities held by all such Holders. For purposes of the preceding parenthetical concerning apportionment, for any Holder of Registrable Securities that is a partnership or corporation, the partners, retired
partners and stockholders of such Holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “selling
Holder,” and any pro rata reduction with respect to such “selling Holder” shall be based upon the relative amount of Registrable Securities owned by such related entities and individuals; 
 (ii) second, any securities which the Company desires to sell for its own account; and 
  

 7 

 (iii) third, among all other stockholders of the Company having registration rights (other
than a Holder); provided, however, that no securities held by such stockholders shall be included in the registration to the extent that the number of Registrable Securities requested by the Holders to be included in such registration
are limited pursuant to Section 3.1(b)(i) above. 
 The Company shall so advise all Holders requesting to be included in the registration
and underwriting of the number of shares of Registrable Securities that may be included in the registration and the underwriting shall be allocated among all Holders requesting to be included in the registration and underwriting in proportion, as
nearly as practicable, to the respective amounts of Registrable Securities held by them at the time of filing the registration statement. No Registrable Securities excluded from the underwriting by reason of the underwriter’s marketing
limitation shall be included in such registration. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares. If
any Holder of Registrable Securities disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company and the shares of Registrable Securities included in the registration and underwriting
shall be reallocated among the remaining Holders of Registrable Securities requesting to be included in the registration and underwriting. 
 3.2 Company Registration. 
 (a) Notice of Registration. If at any
time or from time to time the Company shall determine to register any of its equity securities, either for its own account or the account of stockholders other than the Holders, other than (I) a registration relating solely to employee benefit
plans, (II) a registration relating solely to a Rule 145 transaction, or (III) a registration in which the only equity security being registered is Common Stock issuable upon conversion of convertible debt securities which are also being registered,
the Company will: 
 (i) promptly give written notice thereof to each Holder; and 
 (ii) include in such registration (and any related qualifications including compliance with blue sky laws), and in any underwriting
involved therein, all the Registrable Securities specified in a written request or requests by any Holder, made within twenty (20) calendar days after the date of delivery of such written notice by the Company pursuant to subsection
(i) above. 
 (b) Underwriting. If the registration of which the Company gives notice is for a registered public
offering involving an underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 3.2(a)(i). In such event, the right of any Holder to participate in such registration pursuant to this
Section 3.2 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of the Holder’s Registrable Securities in the underwriting subject to the limitations set forth below. All Holders proposing to
distribute their securities through such underwriting shall (together with the Company and the other Holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the managing
underwriter selected for such underwriting by the Company. Notwithstanding any other provision of this Section 3.2, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten,
the managing underwriter may limit the Registrable Securities to be included in such registration and underwriting shall be allocated in the following priority: 
 (i) first, to the Company; 
  

 8 

 (ii) second, among all Holders of Registrable Securities (pro rata among such selling
Holders on the basis of the respective amounts of Registrable Securities held by all such selling Holders); provided, however, that if such registration is the Initial Public Offering, the managing underwriter may exclude any portion,
and up to all, of the Registrable Securities from such registration; provided, further, that if such registration is other than the Initial Public Offering and notwithstanding Section 3.2(b)(i), the managing underwriter may limit
the number of Registrable Securities to be included to not less than thirty-three percent (33%) of the total shares included in such registration and underwriting. For purposes of the preceding parenthetical concerning apportionment, for any
Holder of Registrable Securities that is a partnership or corporation, the partners, retired partners and stockholders of such Holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any
of the foregoing persons shall be deemed to be a single “selling Holder,” and any pro rata reduction with respect to such “selling Holder” shall be based upon the relative amount of Registrable
Securities owned by such related entities and individuals; and 
 (iii) third, among all other holders of securities of the
Company having registration rights (other than a Holder); provided, however, that no securities held by such stockholders shall be included in the registration to the extent that the number of Registrable Securities requested by the
Holders to be included in such registration are limited pursuant to Section 3.2(b)(ii) above. 
 The Company shall so advise all Holders
requesting to be included in the registration and underwriting of the number of shares of Registrable Securities that may be included in the registration and the underwriting shall be allocated among all the Holders requesting to be included in the
registration and underwriting in accordance with the foregoing allocation method. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder
to the nearest 100 shares. If any Holder disapproves of the terms of any such underwriting, such person may elect to withdraw therefrom by written notice to the Company and the shares of Registrable Securities included in the registration and the
underwriting shall be reallocated among the remaining Holders’ Registrable Securities requested to be included in the registration and underwriting. 
 (c) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 3.2 prior to the effectiveness of such
registration whether or not any Holder has elected to include securities in such registration. 
 3.3 Registration on Form
S-3. 
 (a) Request for Registration. In case the Company shall receive from Holders a written request that the
Company file a registration statement on Form S-3 (or any successor form to Form S-3) for a public offering of shares of the Registrable Securities the aggregate price to the public of which, net of underwriting discounts and commissions, would
exceed $5,000,000, and the Company is a registrant entitled to use Form S-3 to register the Registrable Securities for such an offering, the Company shall (i) promptly advise all Holders of the proposed registration Form S-3, and (ii) use
commercially reasonable efforts to cause such Registrable Securities to be registered for the offering on such form and to cause such

  

 9 

 
Registrable Securities to be qualified in such jurisdictions as such Holder or Holders may reasonably request; provided, however, that the Company shall not be required to effect
more than one registration pursuant to this Section 3.3 in any twelve-month period. If such offer is to be an underwritten offer, the Holders of a majority of the Registrable Securities requested to be registered shall select the managing
underwriter subject to the reasonable approval of the Company. 
 (b) Notwithstanding the foregoing, the Company shall not be
obligated to take any action pursuant to this Section 3.3: 
 (i) during the period that begins sixty (60) days
before the Company’s good faith estimate of the filing of, and that ends one hundred eighty (180) days immediately following the effective date of, any registration statement pertaining to securities of the Company (other than a
registration of securities in a Rule 145 transaction or with respect to an employee benefit plan), provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become
effective; or 
 (ii) If the Company shall furnish to the Holders a certificate signed by the President or Chief Executive
Officer of the Company (A) giving notice of its bona fide intention to effect the filing of a registration statement with the Commission (providing that the Company is actively employing in good faith all reasonable efforts to cause such
registration statement to become effective), or (B) stating that, in the good faith judgment of the Board, it would be seriously detrimental to the Company or its stockholders for a registration statement to be filed in the near future and that
it is, therefore, essentially to defer the filing of such registration statement. In such case, the Company’s obligation to use its commercially reasonable efforts to file a registration statement shall be deferred one or more times each for a
period not to exceed 180 days from the receipt of the request to file such registration by such Holder or Holders, provided that the Company may not exercise this deferral right more than once per twelve-month period. 
 (c) Underwriting. In the event such registration on Form S-3 is to be underwritten as determined by a majority in interest of the
Holders requesting such registration, the right of any Holder to participate in such registration pursuant to this Section 3.3 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of the
Holder’s Registrable Securities in the underwriting subject to the limitations set forth below. All Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other Holders distributing
their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by a majority in interest of the Holders requesting such registration. Notwithstanding
any other provision of this Section 3.3, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter may limit the Registrable Securities to be included
in such registration and the underwriting shall be allocated in the following priority: 
 (i) first, among all Holders of
Registrable Securities (pro rata among such selling Holders on the basis of the respective amounts of Registrable Securities held by all such selling Holders); provided, however, that the aggregate number of Registrable Securities that
may be included in such registration may be limited by such managing underwriter to an amount no less than sixty-six percent (66%) of the total number of shares to be included in such registration and pro rata among Holders of Registrable
Securities on the basis of the Registrable Securities held by all such Holders; 
  

 10 

 (ii) second, any securities which the Company desires to sell for its own account; and

 (iii) third, among all other stockholders of the Company having registration rights (other than a Holder); provided,
however, that no securities held by such stockholders shall be included in the registration to the extent that the number of Registrable Securities requested by the Holders to be included in such registration are limited pursuant to
Section 3.3(c)(i) above. 
 The Company shall so advise all Holders requesting to be included in the registration and
underwriting of the number of shares of Registrable Securities that may be included in the registration and the underwriting shall be allocated among all the Holders requesting to be included in the registration and underwriting in proportion, as
nearly as practicable, to the respective amounts of Registrable Securities held by them at the time of filing the registration statement. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters
may round the number of shares allocated to any Holder to the nearest 100 shares. If any Holder disapproves of the terms of any such underwriting, such person may elect to withdraw therefrom by written notice to the Company and the shares of
Registrable Securities included in the registration and the underwriting shall be reallocated among the remaining Holders’ Registrable Securities requested to be included in the registration and underwriting. 
 3.4 Subsequent Registration Rights. 
 (a) Without the consent of any holder of Registrable Securities hereunder, the Company may grant to any holder of securities of the Company registration rights subordinate to those granted hereunder.

 (b) The Company shall not enter into any agreement granting any holder or prospective holder of any securities of the
Company registration rights superior to, or on a pari passu basis with, the rights granted the Purchasers hereunder without the written consent of the holders of at least a majority in interest of the Purchasers (together on an as-converted
basis). Notwithstanding the foregoing, the Company may, without obtaining any further consent of the holders of Registrable Securities other than as required pursuant to Section 10.1, amend this Agreement to the extent necessary to grant rights
and obligations, on a pari passu basis with the rights and obligations of the Purchasers, to investors in any subsequent round of financing with respect to the securities purchased by such investors in such financing. 
 3.5 Expenses of Registration. All Registration Expenses incurred in connection with (a) two (2) registrations pursuant to
Section 3.1, (b) all registrations pursuant to Section 3.2, and (c) two (2) registrations pursuant to Section 3.3, shall be borne by the Company. Notwithstanding the foregoing, in the event that Initiating Holders cause
the Company to begin a registration pursuant to Section 3.1, and the request for such registration is subsequently withdrawn by the Initiating Holders or such registration is not completed due to failure to meet the net proceeds requirement set
forth in such section or is otherwise not successfully completed due to no fault of the Company, all Holders shall be deemed to have forfeited their right to one

(1) registration under Section 3.1 unless the Initiating Holders pay for, or reimburse the Company for, all of the Registration Expenses incurred in connection with such withdrawn or
incomplete registration; provided, however, that if at the time of such withdrawal, the Holders have learned of a material adverse change in the condition, business, or prospects of the Company from that known to the Holders at the
time of their request and have withdrawn the request with reasonable promptness following disclosure by the Company of such material adverse change, then the Holders shall not be required to pay any of such expenses and shall retain their rights
pursuant to Section 3.1 or 3.3. Unless otherwise stated, all Selling Expenses relating to securities registered on behalf of the Holders shall be borne by the Holders of such securities pro rata on the basis of the number of shares so
registered or proposed to be so registered. 
 3.6 Registration Procedures. In the case of each registration effected by
the Company pursuant to this Agreement, the Company will keep each Holder advised in writing as to the initiation of such registration and as to the completion thereof. The Company will: 
 (a) prepare and file with the Commission a registration statement and such amendments and supplements as may be necessary and use
commercially reasonable efforts to cause such registration statement to become and remain effective for at least ninety (90) days or until the distribution described in the registration statement has been completed, whichever first occurs (such
period to be extended for so long as the underwriters request that the Holders refrain from sales thereunder); 
 (b) furnish
to the Holders participating in such registration and to the underwriters of the securities being registered such reasonable number of copies of the registration statement, preliminary prospectus, final prospectus and such other documents as such
underwriters may reasonably request in order to facilitate the public offering of such securities; 
 (c) use all commercially
reasonable efforts to register and qualify the securities converted by such registration statement under such other securities or blue sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall
not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions; 
 (d) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering; 
 (e) notify each Holder of Registrable Securities covered by
such registration statement of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to
be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; 
 (f) cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities issued by the Company are then listed; and 
  

 12 

 (g) provide a transfer agent and registrar for all Registrable Securities registered
pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration. 
 3.7 Indemnification. 
 (a) The Company will indemnify each Holder, each of
its officers and directors, members and partners, and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which registration has been effected pursuant to this Agreement, against all
expenses, claims, losses, damages or liabilities (or actions in respect thereof), legal fees and disbursements, as incurred, including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on
any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, or based on
any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation by the Company of
the Securities Act, the Exchange Act, state securities laws or any rule or regulation promulgated under such laws applicable to the Company in connection with any such registration, and the Company will reimburse each such Holder, each of its
officers and directors and partners, and each person controlling such Holder, for any legal and any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue
statement or omission, made in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder or controlling person, and stated to be specifically for use in the registration.

 (b) To the extent permitted by law, each Holder will severally and not jointly, if Registrable Securities held by such
Holder are included in the securities as to which such registration is being effected, indemnify the Company, each of its directors and officers, other holders of the Company’s securities covered by such registration statement, each person who
controls the Company within the meaning of Section 15 of the Securities Act, and each other such Holder, each of such Holder’s officers and directors and partners and each person controlling such Holder within the meaning of
Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such
registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any
violation by the Holder of the Securities Act, the Exchange Act, state securities laws or any rule or regulation promulgated under such laws applicable to the Holder, and will reimburse the Company, such other Holders, such directors, officers,
persons, underwriters or control persons for any legal or any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating or defending any such claim, loss, damage, liability or action, but in the case of the
Company or the other Holders or their officers, directors or controlling persons, only to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus,
offering circular or other document in reliance upon and in conformity

  

 13 

 
with information furnished in writing to the Company by such Holder specifically for use in the registration statement. Notwithstanding the foregoing, the liability of each Holder under this
Subsection 3.7(b) shall be limited to the net proceeds resulting from shares sold by such Holder. 
 (c) Each party
entitled to indemnification under this Section 3.7 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after
such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, however,
that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party’s expense; provided, further, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement unless the failure to
give such notice is materially prejudicial to an Indemnifying Party’s ability to defend such action and provided further, that the Indemnifying Party shall not assume the defense for matters as to which there is a conflict of interest or there
are separate and different defenses. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party (whose consent shall not be unreasonably withheld), consent to entry of any judgment
or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. 
 (d) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained on the underwriting
agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. 
 3.8 Information by Holder. The Holder or Holders of Registrable Securities included in any registration shall furnish to the Company
such information regarding such Holder or Holders, the Registrable Securities held by them and the distribution proposed by such Holder or Holders as the Company may reasonably request in writing and as shall be required in connection with any
registration referred to in this Agreement. 
 3.9 Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the Securities Act and any other rule or regulation of the Commission that may at any time permit a Holder to sell securities of the Company to the public without registration or
pursuant to a registration on Form S-3, the Company agrees to: 
 (a) make and keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act, at all times beginning ninety (90) days after the effective date of the Initial Public Offering; 
 (b) file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the
Exchange Act; and 
  

 14 

 (c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith
upon request (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by the Company),
the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies),
(ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or
regulation of the Commission that permits the selling of any such securities without registration or pursuant to such form. 
 3.10 Termination of Registration Rights. The rights granted pursuant to Sections 3.1, 3.2 and 3.3 of this Agreement shall terminate as to any Holder upon the earlier of (a) the date four (4) years after the effective date
of the Initial Public Offering, or (b) the date such Holder is able immediately to sell all shares of Registrable Securities held (or entitled to be held upon conversion) by such Holder under Rule 144 during any 90-day period. 
 4. Standoff Agreement. Each Purchaser, and his or her assignees, agrees in connection with the Initial Public Offering not to sell,
make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any of the Company’s securities (other than those included in the registration or to affiliates) without the prior written consent of the Company or
such underwriters, as the case may be, for such period of time not to exceed one hundred eighty (180) days from the effective date of such registration as may be requested by the underwriters; provided, however, that all officers, directors and
holders of greater than five percent (5%) of the then outstanding capital stock of the Company (calculated on a fully diluted basis) also enter into similar agreements; provided, further, that, if during the last 17 days of the restricted
period the Company issues an earnings release or material news or a material event relating to the Company occurs, or prior to the expiration of the restricted period the Company announces that it will release earnings results during the 16-day
period beginning on the last day of the restricted period, and if the Company’s securities are listed on the Nasdaq Stock Market and Rule 2711 of thereof applies, then the restrictions imposed by this Section 4 shall continue to
apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. In no event will the restricted period extend beyond two hundred fifteen (215) days
after the effective date of the registration statement. Each Purchaser, and his or her assignees, further agrees to enter into a separate agreement providing for the foregoing, as may be required by the underwriters. The Company may impose
stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such period. Notwithstanding the foregoing, such market standoff restrictions shall not apply to the Company’s public securities
acquired during or after such Initial Public Offering. In the event that any person or entity that is bound by restrictions similar to those set forth herein shall be released from such restrictions prior to the end of the period of such
restrictions, then each Purchaser shall similarly be released from the obligations hereunder on a pro rata basis (based on the number of shares held by each such person or entity) to the same extent as such person or entity. 
 5. Right of First Refusal. The Company hereby grants to each Major Purchaser a right of first refusal to purchase its pro rata share
of “New Securities” (as defined in Section 5(a) below) that the Company may, from time to time, after the date hereof propose to sell and issue. Such pro rata share, for purposes of this right of first refusal, is the
ratio of (X) shares of Common Stock issuable or issued upon conversion of the Preferred Stock held by such Major Purchaser, to (Y) the total number of shares of Common Stock then outstanding immediately

  

 15 

 
prior to the issuances of New Securities, after assuming the conversion of all outstanding convertible securities (including the Preferred Stock) into Common Stock and the exercise of all
outstanding options and warrants and including all shares reserved for issuance pursuant to the Company’s 2007 Equity Incentive Plan and regardless of whether such shares are subject to outstanding options. 
 (a) “New Securities” shall mean any Common Stock or Preferred Stock whether or not authorized on the date hereof,
and rights, options, or warrants to purchase any capital stock (including Common Stock or Preferred Stock) and securities of any type whatsoever that are, or may become, convertible into any capital stock (including Common Stock or Preferred Stock);
provided, however, that “New Securities” does not include the following: 
 (i) shares of
Common Stock, or options to purchase or restricted stock units to acquire shares of Common Stock (including all options granted by the Company prior to the date of this Agreement), issued or granted to officers, directors and employees of, or
consultants to, the Company pursuant to a stock grant, employee restricted stock purchase agreement, stock option plan or stock purchase plan or other stock incentive program approved by the Board (collectively, the “Plans”);

 (ii) shares of Common Stock issuable upon conversion of the Preferred Stock; 
 (iii) securities of the Company offered to the public pursuant to the Initial Public Offering; 
 (iv) securities of the Company issued pursuant to the acquisition of another corporation or entity by the Company whether by merger,
purchase of all or substantially all of the assets of, or other reorganization whereby the Company will own more than fifty percent (50%) of the voting stock of such other corporation or entity after the acquisition; 
 (v) securities of the Company issued in connection with equipment lease financing transactions, real estate leases or bank financing
transactions, the principal purpose of which is not to raise equity funding; 
 (vi) securities issued to strategic corporate
partners or in connection with other strategic alliances on terms approved by a majority of the Board; 
 (vii) securities of
the Company issued in connection with any stock split, stock dividend or, except as described in (ix) below, a recapitalization by the Company; 
 (viii) securities pursuant to other plans or arrangements approved by the Board, the principal purpose of which is not to raise equity financing; 
 (ix) up to $30 million of shares of Series B Preferred (and shares of Common Stock issued upon conversion thereof) issued in one or more
related transactions at a price per share of not less than $120.93; and 
  

 16 

 (x) shares of Series A-1 Preferred (and shares of Common Stock issued upon conversion
thereof) and warrants to purchase shares of Series A-1 Preferred (and shares of Series A-1 Preferred issued upon exercise thereof, and shares of Common Stock issued upon conversion of such shares of Series A-1 Preferred) issued in connection with
the Exchange (as defined in the Purchase Agreement). 
 (b) In the event that the Company proposes to undertake an issuance of
New Securities, it shall give each Major Purchaser written notice of its intention, describing the type of New Securities, the price, and the general terms upon which the Company proposes to issue the same. Each Major Purchaser shall have thirty
(30) days after receipt of such notice to agree to purchase all or a portion of its pro rata share, as calculated pursuant to this Section 5, of such New Securities at the price and upon the terms specified in the notice by giving written
notice to the Company and stating therein the quantity of New Securities to be purchased. 
 (c) After giving the notice set
forth in Section 5(b) above, the Company shall have one hundred twenty (120) days thereafter to sell (or enter into an agreement pursuant to which the sale of New Securities covered thereby shall be closed, if at all, within sixty
(60) days from the date of said agreement) the New Securities not elected or eligible to be purchased by the Major Purchasers, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice. In
the event the Company has not sold the New Securities within such one hundred twenty (120) day period (or sold and issued New Securities in accordance with the foregoing within sixty (60) days from the date of such agreement) the Company
shall not thereafter issue or sell any of the New Securities, without again first offering such New Securities to the Major Purchasers in the manner provided above. 
 (d) The right of first refusal granted under this Section 5 shall expire upon the earlier of the closing of (a) the Initial Public Offering, or (b) a Change of Control Transaction.

 6. Transfer of Rights. The rights granted under Sections 2, 3, and 5 of this Agreement may be assigned to any
transferee or assignee, other than a competitor of the Company (as determined in good faith by the Board) in connection with any transfer or assignment of Registrable Securities by the Holder, provided that: (a) such transfer is otherwise
effected in accordance with applicable securities laws and the terms of this Agreement; (b) such assignee or transferee acquires at least 12,800 shares (each, on an as-converted to common stock basis, as adjusted for stock splits, stock
dividends, stock combinations and the like) of Registrable Securities (including Preferred Stock convertible into Registrable Securities), (c) written notice is promptly given to the Company; and (d) such transferee or assignee agrees to
be bound by the provisions of this Agreement. Notwithstanding the foregoing, the rights granted to the Holders hereunder may be assigned without compliance with item (b) above to any limited partner, retired partner, constituent partner or
member of a Holder which is a partnership or limited liability company, to any subsidiary, parent or shareholder of a Holder which is a corporation, or to an affiliate (as such term is defined in Rule 405 of the Securities Act) of a Holder which is
a corporation, partnership or limited liability company or to a Holder’s family members or trust for the benefit of an individual Holder and his or her family members. 
 7. Right of First Refusal on Proposed Sales by the Founder and Purchasers. In addition to the Co-Sale Rights on proposed sales or
transfers by the Founder contained in Section 8 below, the following shall also apply. 
  

 17 

 7.1 First Refusal Notice. If the Founder or any Purchaser proposes to sell or
transfer (other than transfers that are exempt under Section 7.5 below) any capital stock of the Company held by the Founder or such Purchaser in one or more related transactions, the Founder or such Purchaser (a “Proposed
Seller”) shall promptly give written notice (the “First Refusal Notice”) to the Company and each Major Purchaser at least thirty-five (35) calendar days prior to the closing of such sale or transfer. The
First Refusal Notice shall describe in reasonable detail (a) the number and class of shares to be sold by the Proposed Seller, (b) the date or proposed date of such transfer and the name and address of the transferee (the
“Acquiror”) and (c) the principal terms of such proposed sale or transfer, including the cash or other property or consideration to be received upon such transfer. The Company and the Major Purchasers agree to keep the
information contained in the First Refusal Notice confidential if so requested by the Proposed Seller. 
 7.2 Company’s
Option. The Company shall have the option, but not the obligation, to purchase all but not less than all of the shares offered by the Proposed Seller on the same terms as specified in the First Refusal Notice. Within ten (10) calendar days
after the date the First Refusal Notice is deemed delivered, the Company shall give written notice to the Proposed Seller and to the Major Purchasers stating its intention to exercise such option, and a date and time for consummation of the purchase
not less than ten (10) calendar days nor more than twenty (20) calendar days after the date the First Refusal Notice is deemed delivered. Failure by the Company to give such notice within such time period shall be deemed an election by it
not to exercise its option; provided, however, that the exercise or non-exercise of the rights of the Company hereunder to participate in one or more sales of the Proposed Seller’s shares made by the Proposed Seller shall not
adversely affect the Company’s rights to participate in subsequent sales of the Proposed Seller’s shares subject to this Section 7. 
 7.3 Major Purchasers’ Exercise of Right of First Refusal. 
 (a) If the
Company fails to exercise its option contained in Section 7.2 above in full, each Major Purchaser shall have the option, but not the obligation, to purchase its respective Pro Rata Share (as defined below) on the same terms as specified in the
First Refusal Notice. After the expiration of the 10-day period in Section 7.2 above, but within thirty (30) calendar days after the date the First Refusal Notice is deemed delivered, any electing Major Purchaser shall give written notice
to the Proposed Seller and the Company stating that it elects to exercise its right of first option and a date and time for consummation of the purchase not more than forty (40) calendar days after the date the First Refusal Notice is deemed
delivered. Failure by a Major Purchaser to give such notice within such time period shall be deemed an election by it not to exercise its option; provided, however, that the exercise or non-exercise of the rights of each Major
Purchaser hereunder to participate in one or more sales of the Proposed Seller’s shares made by the Proposed Seller shall not adversely affect their rights to participate in subsequent sales of the Proposed Seller’s shares subject to this
Section 7. 
 (b) “Pro Rata Share” of each Major Purchaser for the purposes of this Section 7
shall be calculated as of the date of the First Refusal Notice and shall be determined by multiplying the number of shares proposed to be sold by the Founder as set forth in the First Refusal Notice (less any shares purchased by the Company pursuant
to Section 7.2 above) by the quotient obtained by dividing: 
 (i) the number of shares of Common Stock issuable or
issued upon conversion of all shares of outstanding Preferred Stock then held by such Major Purchaser, by 
  

 18 

 (ii) the number of shares of Common Stock issuable or issued upon conversion in full of all
outstanding shares of Preferred Stock then held by all such Major Purchasers. 
 7.4 Sale of Proposed Seller’s Shares to
Third Party. To the extent that the Major Purchasers do not elect to participate in the sale of the Proposed Seller’s shares subject to the First Refusal Notice, the Proposed Seller may, not later than sixty (60) calendar days after
the date the First Refusal Notice is deemed delivered (subject to the Co-Sale Rights of the Major Purchasers contained in Section 8, below), enter into an agreement providing for the closing and transfer of the balance of the Proposed
Seller’s shares covered by the First Refusal Notice on terms and conditions no more favorable to the Acquiror than those described in the First Refusal Notice. Any proposed transfer on terms and conditions more favorable than those described in
the First Refusal Notice, as well as any subsequent proposed transfer of any of the balance of the Proposed Seller’s shares by such Proposed Seller, shall again be subject to the rights of first refusal (and Co-Sale Rights) of the Major
Purchasers, and shall require compliance by the Proposed Seller with the procedures described in this Section 7 and Section 8 below. 
 7.5 Exempt Transfers. 
 (a) Notwithstanding the foregoing, the provisions
of this Section 7 shall not apply to the following: (i) any Permitted Transfer (as defined below); (ii) all sales, transfers or other dispositions by the Proposed Seller of shares of capital stock held by such Proposed Seller up to an
aggregate for all such sales, transfers or dispositions of 500 shares (as adjusted for stock splits, stock dividends, combinations, recapitalizations, and the like); (iii) any repurchase of the Founder’s shares by the Company pursuant to
such Founder’s stock purchase agreement; or (iv) any bona fide gift or pledge; provided that (A) the Proposed Seller shall inform the Major Purchasers of such pledge, Permitted Transfer or gift prior to effecting it, and (B) the
pledgee, Permitted Transferee or donee shall agree in writing to be bound by and comply with all provisions of this Agreement and any and all other stock restrictions that the Company may reasonably request. Such transferred Proposed Seller’s
shares shall remain subject to the provisions of this Section 7, and such pledgee, Permitted Transferee or donee shall be treated as a “Founder or Purchaser” for purposes of this Agreement. For the purposes hereof,
“Permitted Transfer” shall mean any sale, transfer or other disposition of the Company’s securities to any spouse (or ex-spouse), parents, brothers, sisters, children (natural or adopted), stepchildren or grandchildren,
a trust exclusively for any of their benefit or for the benefit of the transferor, a transfer by a Purchaser to any person or entity that is an affiliate of such Purchaser by virtue of controlling, being controlled by or under common control with
such Purchaser, or any other transfer not involving a change in the beneficial ownership of the Company’s securities (each, a “Permitted Transferee”); provided, however, that, prior to such transfer, such
Permitted Transferee shall agree in writing to be bound by the terms and conditions of this Agreement. For purposes of this Section 7.5, LLCs shall be considered partnerships and members of LLCs shall be considered partners. 
  

 19 

 (b) Notwithstanding the foregoing, the provisions of this Section 7 shall not apply to
the sale of any of the Proposed Seller’s shares (i) to the public pursuant to a registration statement filed with, and declared effective by, the Commission under the Securities Act, (ii) to the Company, (iii) to any corporate or
other affiliates of the Proposed Seller, or (iv) if the Proposed Seller is a partnership, to an affiliated partnership, a partner of such partnership or a retired partner of such partnership who retires after the date hereof, or to the estate
of any such partner or retired partner or the transfer by gift, will or intestate succession of any partner to his or her spouse or to the siblings, lineal descendants or ancestors of such partner or his or her spouse. 
 7.6 Prohibited Transfers. Any attempted transfer in violation of the terms of this Section 7 shall be ineffective to vest in any
transferee any interest held by the Proposed Seller in the shares. Without limiting the foregoing, any purported transfer in violation hereof shall be ineffective as against the Company, and the Company and the Major Purchasers shall have a
continuing right and option (but not an obligation), until the restrictions contained in this Section 7 terminate, to purchase the securities purported to be transferred by the Proposed Seller in violation of this Section 7 for a price and
on terms the same as those at which the purported transfer was effected. The Company may impose stop-transfer restrictions with respect to the shares subject to the foregoing right of first refusal consistent with the provisions of this
Section 7. 
 7.7 Restrictive Legends. All certificates representing the Founder’s and each Purchaser’s
shares that are subject to the provisions of this Section 7, including any other securities issued in respect of such shares upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall (unless otherwise
permitted or unless the securities evidenced by such certificate are no longer subject to this Section 7) be stamped or otherwise imprinted with a legend substantially in the following form: 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RIGHTS OF FIRST REFUSAL AND CO-SALE RIGHTS AS SET FORTH IN THAT CERTAIN
INVESTORS’ RIGHTS AGREEMENT, AND ANY AMENDMENT THERETO OR RESTATEMENTS THEREOF, BY AND AMONG THE COMPANY, THE FOUNDER AND CERTAIN OTHER SIGNATORIES THERETO, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICE OF THE COMPANY. BY
ACCEPTING AN INTEREST IN SUCH SECURITIES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE WITH AND MAY BE BOUND BY THE PROVISIONS OF SUCH AGREEMENT. 
 Upon request of a holder of such a certificate, the Company shall remove the foregoing legend from the certificate or issue to such holder a new certificate therefor free of such restrictive legend, if
with such request, the Company shall have received an opinion of counsel, reasonably acceptable to the Company, to the effect that such shares are no longer subject to the provisions of this Section 7 and Section 8, below. 
 7.8 Transfer or Assignment of Right of First Refusal. This Right of First Refusal may be transferred or assigned by any Major
Purchaser to a transferee or assignee of at least 12,800 shares of Preferred Stock, Conversion Stock or a combination thereof (each, on an as-converted to common stock basis, as adjusted for stock splits, stock dividends, combinations,

  

 20 

 
recapitalizations, and the like); provided, however, that (a) the Company is given written notice by such Major Purchaser within two (2) business days prior to such
transfer or assignment of such Preferred Stock, stating the name and address of said transferee or assignee and identifying the securities with respect to which such rights are being transferred or assigned; (b) the transferee or assignee of
such rights is not deemed by the Board, in its reasonable judgment, to be a competitor of the Company; and (c) the transferee or assignee of such rights assumes in writing the obligations of such Major Purchaser under this Agreement.

 7.9 Termination of Right of First Refusal. The rights, obligations and limitations set forth under this Section 7
will terminate immediately prior to the earlier to occur of (a) the closing of the Initial Public Offering, (b) the date on which this Agreement is terminated by a writing executed by the parties hereto, (c) the dissolution of the
Company, or (d) the closing of a Change of Control Transaction. 
 7.10 Waiver. Subject to Section 10.2, the
rights granted to the Major Purchasers in Section 7.3 as to any proposed sales by a Proposed Seller may be waived as to all Major Purchasers upon the written consent of the holders of at least fifty percent (50%) of the Preferred Stock
held by such Major Purchasers, voting together as a single class on an as-converted basis. 
 8. Co-Sale Right. Subject
to the prior exercise of and in addition to the Right of First Refusal on proposed sales or transfers by the Founder contained in Section 7 above, the following shall also apply: 
 8.1 Co-Sale Notice. The First Refusal Notice delivered pursuant to Section 7.1 above, shall be deemed notice for purposes of the
co-sale rights contained in this Section 8. 
 8.2 Exercise of Co-Sale Rights. If the Company fails to exercise its
option contained in Section 7.2 above, and one or all of the Major Purchasers fails to give written notice of the exercise of its option to purchase its respective Pro Rata Share within thirty (30) calendar days after the First Refusal
Notice is given as provided in Section 7.3 above, thereby waiving their respective Rights of First Refusal, the remaining shares proposed to be sold by the Founder as set forth in the First Refusal Notice shall be subject to the following
Co-Sale Rights exercisable by the Major Purchasers, regardless of whether such Major Purchasers had or had not exercised their respective rights of first refusal contained in Section 7 above. 
 8.3 Mechanics of Co-Sale. Each Major Purchaser electing to participate (the “Participants”) will effect its
participation in the sale by promptly delivering to the Founder, and no later that thirty-five (35) calendar days after the delivery of First Refusal Notice, for transfer to the Acquiror one or more certificates, properly endorsed for transfer,
which represent: 
 (a) the type and number of shares of Common Stock which such Participant elects to sell up to the
Participants’ Pro Rata Share, which, for purposes of this Section 8, shall be calculated as of the date of the First Refusal Notice and shall be determined by multiplying the number of shares proposed to be sold by the Founder as set forth
in the First Refusal Notice (less any shares purchased by the Company and/or the Major Purchasers pursuant to Section 7 above) by the quotient obtained by dividing (X) the number of shares of Common Stock issuable or issued upon conversion
of all shares of outstanding Preferred Stock then held by such Participant, by (Y) the number of shares of Common Stock issuable or issued upon conversion in full of all outstanding shares of capital stock then held by the Founder and all
Participants; or 
  

 21 

 (b) that number of shares of Preferred Stock which is at such time convertible into the
number of shares of Common Stock which such Participant elects to sell up to the Participants’ Pro Rata Share (as determined pursuant to Section 8.3(a) above); provided, however, that if the Acquiror objects to the delivery
of Preferred Stock in lieu of Common Stock, such Participant shall convert such Preferred Stock into Common Stock and deliver Common Stock as provided in this Section 8.3. The Company agrees to make any such conversion that is otherwise
permitted concurrent with the actual transfer of such shares to the Acquiror. 
 The stock certificate or certificates that the Participant
delivers to the Founder shall be transferred to the Acquiror in consummation of the sale of the Founder’s shares pursuant to the terms and conditions specified in the First Refusal Notice, and the Founder shall concurrently therewith remit to
such Participant that portion of the sale proceeds to which such Participant is entitled by reason of its participation in such sale. To the extent that any Acquiror prohibits such assignment or otherwise refuses to purchase shares or other
securities from a Participant exercising its rights of co-sale hereunder, the Founder shall not sell to such Acquiror any of the Founder’s shares unless and until, simultaneously with such sale, the Founder shall purchase such
Participant’s Pro Rata Share as determined pursuant to Section 8.3(a) above from such Participant at the price and on the terms specified in the Founder’s First Refusal Notice. 
 8.4 Sale of Founder’s Shares to Third Party. Subject to Section 7 of this Agreement regarding rights of first refusal of
the Company and the Major Purchasers, if none of the Major Purchasers elects to exercise their co-sale rights to sell their respective Pro Rata Share (as determined pursuant to Section 8.3(a)) above pursuant to this Section 8, the Founder
may, not later than sixty (60) calendar days after the date the First Refusal Notice is deemed delivered, enter into an agreement providing for the closing and transfer of the balance of the Founder’s shares covered by the First Refusal
Notice on terms and conditions no more favorable to the Acquiror or the Founder than those described in the First Refusal Notice. Any proposed transfer on terms and conditions more favorable than those described in the First Refusal Notice, as well
as any subsequent proposed transfer of any of the balance of the Founder’s shares by the Founder, shall again be subject to the co-sale rights (and right of first refusal) of the Major Purchasers, and shall require compliance by the Founder
with the procedures described in Section 7, above, and this Section 8. 
 8.5 Transfers Void. If the Founder
sells any of such Founder’s shares in contravention of this Section 8 (a “Prohibited Transfer”), each of the Major Purchasers, in addition to such other remedies as may be available at law, in equity or hereunder,
shall have the option to sell to the Founder such parties’ Pro Rata Share (as determined pursuant to Section 8.3(a) above) and the Founder shall be obligated to purchase such parties’ Pro Rata Share (as determined pursuant to
Section 8.3(a) above) at the price per share equal to the price per share paid by the Acquiror to the Founder in the Prohibited Transfer. The Founder shall also reimburse such Major Purchasers, for any and all reasonable fees and expenses,
including legal fees and expenses, incurred pursuant to the exercise or the attempted exercise of such parties’ rights under this Section 8. Within ninety (90) days after the later of the dates on which such Major Purchasers
(a) received notice of the Prohibited Transfer or (b) otherwise became aware of the Prohibited Transfer, each of such Major Purchasers shall, if exercising the option created hereby, deliver to the Founder the certificate or certificates
representing shares to be sold, each

  

 22 

 
certificate to be properly endorsed for transfer. The Founder shall, upon receipt of the certificate or certificates for the shares to be sold by a Major Purchaser, pursuant to this
Section 8.5, pay the aggregate purchase price therefor and the amount of reimbursable fees and expenses, as specified in cash or by other means acceptable to such Major Purchaser. Notwithstanding the foregoing, any attempt by the Founder to
transfer the Founder’s shares in violation of this Section 8 shall be voidable and the Company agrees it will not effect such a transfer nor will it treat any alleged transferee as the holder of such shares without the written consent of a
majority of the Major Purchasers (as determined on the basis of number of shares held on an as-converted basis), voting together as a single class on an as-converted basis. 
 8.6 Exempt Transfers. Notwithstanding the foregoing, the exempt transfers provided in Section 7.5 above shall also be exempt
from the co-sale rights contained in this Section 8. 
 8.7 Transfer or Assignment of Co-Sale Rights. The Co-Sale
Rights contained in this Section 8 may be transferred or assigned by any Major Purchaser to a transferee or assignee of at least 12,800 shares of Preferred Stock, Conversion Stock or a combination thereof (each, on an as-converted to common
stock basis, as adjusted for stock splits, stock dividends, combinations, recapitalizations and the like); provided, however, that (a) the Company is given written notice by such Purchaser within two (2) business days prior
to such transfer or assignment of such Preferred Stock, stating the name and address of said transferee or assignee and identifying the securities with respect to which such rights are being transferred or assigned; (b) the transferee or
assignee of such rights is not deemed by the Board, in its reasonable judgment, to be a competitor of the Company; and (c) the transferee or assignee of such rights assumes in writing the obligations of such Major Purchaser under this
Agreement. 
 8.8 Termination of Restrictions. The rights and obligations under this Section 8 will terminate
immediately prior to the earlier to occur of (a) the closing of the Initial Public Offering, (b) the date on which this Agreement is terminated by a writing executed by the parties hereto, (c) the dissolution of the Company or
(d) the closing of a Change of Control Transaction. 
 8.9 Waiver. Subject to Section 10.2, the rights granted
to the Major Purchasers in Section 8.2 as to any proposed sales by a Purchaser may be waived as to all Major Purchasers upon the written consent of the holders of at least fifty percent (50%) of the Preferred Stock held by such Major
Purchasers, voting together as a single class on an as-converted basis. 
 9. Restrictions on Transferability.

 9.1 Restrictions on Transferability. Except upon the conditions specified in this Agreement, including Section 9.3
below, which conditions are intended to insure compliance with the provisions of the Securities Act and further subject to Section 4 hereof, each Purchaser agrees not to make any disposition of all or any portion of the Registrable Securities
unless and until the transferee agrees in writing for the benefit of the Company to take and hold those securities subject to the provisions and upon the conditions specified in this Agreement and until such transferee has executed a counterpart
signature page to this Agreement. 
 9.2 Restrictive Legends. All certificates representing any securities of the Company
that are subject to this Agreement, including (a) the shares of the Company’s capital stock owned by the Founder, (b) the Preferred Stock, (c) the shares of the Company’s Common

  

 23 

 
Stock issued upon conversion of the Preferred Stock or the exercise of warrants by Purchasers, SVB, or AEI, and (d) any other securities issued in respect of the Founder’s shares,
Preferred Stock, or the Common Stock issued upon conversion of the Preferred Stock upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall (unless otherwise permitted or unless the securities evidenced
by such certificate shall have been registered under the Securities Act) be stamped or otherwise imprinted with a legend substantially in the following form (in addition to any legend required under applicable state securities laws): 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED, (THE “ACT’) OR REGISTERED OR QUALIFIED UNDER ANY STATE SECURITIES LAWS. SUCH SHARES MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF SUCH REGISTRATION OR QUALIFICATION OR AN OPINION OF COUNSEL
REASONABLY SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION OR QUALIFICATION IS NOT REQUIRED UNDER THE ACT OR ANY APPLICABLE STATE SECURITIES LAWS. COPIES OF THE AGREEMENTS COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING
THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF FORCE10 NETWORKS, INC. AT THE PRINCIPAL EXECUTIVE OFFICE OF THE COMPANY. 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE CONDITIONS SPECIFIED IN THE AMENDED AND RESTATED INVESTORS’ RIGHTS
AGREEMENT AND ANY AMENDMENT THERETO OR RESTATEMENTS THEREOF (SUCH AGREEMENT INCLUDING ANY SUCH AMENDMENTS OR RESTATEMENTS, THE “AGREEMENT’) BY AND AMONG FORCE10 NETWORKS, INC. AND CERTAIN OTHER SIGNATORIES THERETO, AND BY
ACCEPTING ANY INTEREST IN SUCH SECURITIES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE AND SHALL BECOME BOUND BY ALL THE PROVISIONS, INCLUDING THE VOTING PROVISIONS, OF SAID AGREEMENT. A COPY OF THE AGREEMENT MAY BE OBTAINED AT NO
COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF FORCE10 NETWORKS, INC. 
 Upon request of a holder
of such a certificate, the Company shall remove the foregoing legend from the certificate or issue to such holder a new certificate therefor free of any transfer legend, if with such request, the Company shall have received either the opinion
referred to in Section 9.3(a) or the “no-action” letter referred to in Section 9.3(b) to the effect that any transfer

  

 24 

 
by such holder of the securities evidenced by such certificate will not violate the Securities Act and applicable state securities laws, unless any such transfer request is made after the Initial
Public Offering or unless any such transfer legend may be removed pursuant to Rule 144(k), in which case no such opinion or “no-action” letter shall be required; provided, however, that the Company shall
not be obligated to remove any such legends prior to the date of the initial Public Offering. 
 9.3 Notice of Proposed
Transfers. The holder of each certificate representing securities by acceptance thereof agrees to comply in all respects with the provisions of this Section 9.3. Prior to any proposed transfer of any securities (other than pursuant to an
effective registration statement under the Securities Act), the holder thereof shall give written notice to the Company of such holder’s intention to effect such transfer. Each such notice shall describe the manner and circumstances of the
proposed transfer in sufficient detail, and shall be accompanied by either: 
 (a) a written opinion of legal counsel to the
holder who shall be reasonably satisfactory to the Company, addressed to the Company and reasonably satisfactory in form and substance to the Company’s counsel, to the effect that the proposed transfer of the Registrable Securities may be
effected without registration under the Securities Act, provided, however, that the Company will not require opinions of counsel for transactions made after the Initial Public Offering or for transactions pursuant to Rule 144 and the Company may
waive this requirement at the Company’s discretion, or 
 (b) a “no-action” letter from the
Commission to the effect that the distribution of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such securities shall be
entitled to transfer such securities in accordance with the terms of the notice delivered by such holder to the Company. 
 10.
Miscellaneous. 
 10.1 Arbitration. Any claims arising under this Agreement shall be resolved in binding
arbitration with a duly authorized representative of the American Arbitration Association (“AAA”) in accordance with the provisions hereof and thereof. Either the Company or any Purchaser may submit the matter to binding
arbitration before the AAA in Santa Clara County, California, which arbitration shall be final and binding on the parties and the exclusive method, absent agreement between the Company and the Purchasers, for purposes of determining the ability of
the Company to satisfy such claim. All claims shall be settled by a single arbitrator appointed in accordance with the Commercial Arbitration Rules then in effect of the AAA (the “AAA Rules”). The arbitrator shall render a
final decision pursuant to the AAA Rules within thirty (30) days after filing of the claim. The final decision of the arbitrator shall be furnished to the Investors and the Company in writing and shall constitute the conclusive determination of
the issue in question binding upon the Investors and the Company, and shall not be contested by any of them except as provided by law. Such decision may be used in a court of law only for the purpose of seeking enforcement of the arbitrator’s
decision. The prevailing party shall be entitled to reasonable attorney’s fees, costs and necessary disbursements in addition to any other relief that such party may be entitled. For purposes of this Agreement, the prevailing party shall be
that party in whose favor final judgment is rendered or who substantially prevails, if both parties are awarded judgment. 
  

 25 

 10.2 Waivers and Amendments. Except as provided elsewhere in this Agreement, with the
written consent of the Company and Purchasers, and, if and as specifically set forth below, SVB and AEI, holding more than fifty percent (50%) of the then-outstanding shares of Registrable Securities and Preferred Stock (on an as-converted
basis) held by all Purchasers, and, if an as specifically set forth below, SVB and AEI, the obligations of the Company and the rights of the Purchasers, SVB and AEI under this Agreement may be waived (either generally or in a particular instance,
either retroactively or prospectively and either for a specified period of time or indefinitely), and with the same consent, the Company, when authorized by resolution of the Board, may amend this Agreement or enter into a supplementary agreement
for the purpose of adding any provisions to this Agreement; provided, however, that no obligation of any Holder may be increased and no new obligation may be added without the written consent of such Holder; provided,
further, that Sections 7 and 8 of this Agreement may only be amended, waived, or otherwise changed with the prior written consent of (1) the Founder, (2) the Company and (3) Purchasers, and, if and as specifically set forth
below, SVB and AEI, holding more than fifty percent (50%) of the then-outstanding shares of Registrable Securities and Preferred Stock (on an as-converted basis) held by all Purchasers, and, if and as specifically set forth below, SVB and AEI.
Notwithstanding anything to the contrary set forth in this Section, the shares of the Company’s capital stock issuable to SVB or AEI upon exercise of their respective warrants will not be counted or included as shares entitled to participate in
any vote, agreement or consent approving same unless and until such warrants have been exercised with respect to such shares and, in such case, those shares held by SVB will only be counted or included as shares entitled to participate in any vote,
agreement or consent, with respect to Sections 3.2 through 3.10, 4, 6, 9 and 10 of the Agreement (or their successor provisions), as the same may be amended or restated from time to time. Neither this Agreement nor any provisions hereof may be
changed, waived, discharged or terminated orally, but only by a signed statement in writing. Any amendment, waiver or supplementary agreement effected in accordance with this paragraph shall be binding upon each Purchaser of any Registrable
Securities then outstanding, each future holder of such Registrable Securities and the Company. 
 10.3 Notices. All
notices and other communications required or permitted hereunder shall be in writing and shall be sent by facsimile, overnight courier service, mailed by first-class mail, postage pre-paid, or delivered either by hand or by messenger, addressed

Company, at its address and facsimile number set forth below the signature of the authorized officer of the Company, below, or at such other address and facsimile number as such the Company shall have furnished to the Purchasers, and each such other
holder in writing; in addition, if to the Company, a copy of such notice and other communications shall be sent to Fenwick & West LLP, Silicon Valley Center, 801 California Street, Mountain View, California 94041, Attn: Mark Leahy
(facsimile number: (650) 938-5200). 
 10.4 Descriptive Headings. The descriptive headings herein have been inserted
for convenience only and shall not be deemed to limit or otherwise affect the construction of any provisions hereof.

 26

including counterparts transmitted by facsimile, each of which shall for all purposes be deemed to be an original and all of which shall constitute the same instrument.

parties to this Agreement.

agreement between the parties with regard to the subject matter of this Agreement and shall supersede any prior agreement, understanding or representation with respect to the subject matter hereof including, without limitation, the Investors’
Rights Agreement. 
 10.9 Separability: Severability. Unless expressly provided in this Agreement, the rights of each
Purchaser under this Agreement are several rights, not rights jointly held with any other Purchaser. Any invalidity, illegality or limitation on the enforceability of this Agreement with respect to any Purchaser shall not affect the validity,
legality or enforceability of this Agreement with respect to the other Purchaser. If any provision of this Agreement is judicially determined to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining
provisions shall not be affected or impaired. 
 10.10 Stock Splits. All references to numbers of shares in this
Agreement shall be appropriately adjusted to reflect any stock dividend, split, combination or other recapitalization of shares by the Company occurring after the date of this Agreement. 
 10.11 New Purchasers. Any person or entity who received Series A Preferred pursuant to the Merger Agreement, or subsequent purchaser
of Series B Preferred Stock pursuant to Section 2.2 of the Purchase Agreement (each, a “Subsequent Purchaser”), may become a party to this Agreement after the date hereof without the consent of any of the other parties
hereto by executing a counterpart signature page to this Agreement; provided, however, that, in the case of the persons and entities who received Series A Preferred pursuant to the Merger Agreement, such executed counterpart signature
page to this Agreement must be received by the Company on or before July 1, 2009. As a condition to becoming a party to this Agreement, each Subsequent Purchaser hereby agrees that it shall be deemed to be a “Purchaser”
for all purposes under this Agreement, subject to and bound by all of the terms and conditions applicable to a “Purchaser” under this Agreement. 
 10.12 Aggregation of Stock. All shares of Registrable Securities held or acquired by affiliated entities or persons shall be aggregated together for the purpose of determining the availability of
any rights under this agreement.

 Exhibit 10.1 
 INDEMNIFICATION AGREEMENT 
 This Indemnification
Agreement (“Agreement”) is effective as of             , 2009, by and between Force10 Networks, Inc., a Delaware corporation (the “Company” or
“Force10”), and                      (Name) (“Indemnitee”). 
 WHEREAS, in order to induce Indemnitee to provide, or continue to provide, services to the Company, the Company wishes to provide for the
indemnification of, and advancement of expenses to, Indemnitee to the maximum extent permitted by law; 
 WHEREAS, Indemnitee
does not regard the current protection available as adequate under the present circumstances, and the Indemnitee and other directors, officers, employees, agents and fiduciaries of the Company may not be willing to continue to serve in such
capacities without additional protection; 
 WHEREAS, the Company and Indemnitee recognize the continued difficulty in obtaining
liability insurance for the Company’s directors, officers, employees, agents and fiduciaries, the significant increases in the cost of such insurance and the general reductions in the coverage of such insurance; 
 WHEREAS, the Company and Indemnitee further recognize the substantial increase in corporate litigation in general, subjecting directors,
officers, employees, agents and fiduciaries to expensive litigation risks at the same time as the availability and coverage of liability insurance has been severely limited; and 
 WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on
behalf of, Indemnitee to the fullest extent permitted by applicable law so that Indemnitee will serve or continue to serve the Company free from undue concern that he or she will not be so indemnified. 
 NOW, THEREFORE, in consideration of the foregoing and Indemnitee’s agreement to provide, or continue to provide, services to the
Company, the Company and Indemnitee hereby agree as set forth below. 
 1. Certain Definitions. 
 (a) “Change in Control” shall mean, and shall be deemed to have occurred if, on or after the date of this
Agreement, (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other than a trustee or other fiduciary holding securities under an employee benefit plan of the
Company acting in such capacity or a corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company, becomes the “beneficial owner” (as defined
in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing more than 20% of the total voting power represented by the Company’s then outstanding Voting Securities, (ii) during any period of two
consecutive years, individuals who at the beginning of such period constitute the Board of Directors of the Company and any new director whose

 
election by the Board of Directors or nomination for election by the Company’s stockholders was approved by a vote of at least two thirds (2/3) of the directors then still in office who
either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof, or (iii) the stockholders of the Company approve a merger or
consolidation of the Company with any other corporation other than a merger or consolidation which would result in the Voting Securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or
by being converted into Voting Securities of the surviving entity) at least 80% of the total voting power represented by the Voting Securities of the Company or such surviving entity outstanding immediately after such merger or consolidation, or the
stockholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of (in one transaction or a series of related transactions) all or substantially all of the Company’s
assets. 
 (b) “Claim” shall mean any threatened, pending or completed action, suit, proceeding or
alternative dispute resolution mechanism, or any hearing, inquiry or investigation that Indemnitee in good faith believes might lead to the institution of any such action, suit, proceeding or alternative dispute resolution mechanism, whether civil,
criminal, administrative, whether formal or informal, investigative or other. 
 (c) References to the
“Company” shall include, in addition to Force10, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger to which Force10 (or any of its wholly owned subsidiaries) is a party which, if
its separate existence had continued, would have had power and authority to indemnify its directors, officers, employees, agents or fiduciaries, so that if Indemnitee is or was a director, officer, employee, agent or fiduciary of such constituent
corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, employee benefit plan, trust or other enterprise, Indemnitee
shall stand in the same position under the provisions of this Agreement with respect to the resulting or surviving corporation as Indemnitee would have with respect to such constituent corporation if its separate existence had continued. 

(d) “Expenses” shall mean any and all expenses (including attorneys’ fees and all other costs, expenses and
obligations incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to defend, to be a witness in or to participate in, any action, suit, proceeding, alternative dispute
resolution mechanism, hearing, inquiry or investigation, whether formal or informal), judgments, fines, penalties and amounts paid in settlement (if such settlement is approved in advance by the Company, which approval shall not be unreasonably
withheld) of any Claim regarding any Indemnifiable Event and any federal, state, local or foreign taxes imposed on the Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement. 
 (e) “Expense Advance” shall mean an advance payment of Expenses to Indemnitee pursuant to Section 3(a).

  

 2 

 (f) “Indemnifiable Event” shall mean any event or occurrence
related to the fact that Indemnitee is or was a director, officer, employee, agent or fiduciary of the Company, or any subsidiary of the Company, or is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary
of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action or inaction on the part of Indemnitee while serving in such capacity. 
 (g) “Independent Legal Counsel” shall mean an attorney or firm of attorneys, selected in accordance with the
provisions of Section 2(b) hereof, who shall not have otherwise performed services for the Company or Indemnitee within the last three years (other than with respect to matters concerning the rights of Indemnitee under this Agreement, or of
other indemnitees under similar indemnity agreements). 
 (h) References to “other enterprises” shall
include employee benefit plans; references to “fines” shall include any excise taxes assessed on Indemnitee with respect to an employee benefit plan; and references to “serving at the request of the Company” shall include any
service as a director, officer, employee, agent or fiduciary of the Company which imposes duties on, or involves services by, such director, officer, employee, agent or fiduciary with respect to an employee benefit plan, its participants or its
beneficiaries; and if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan, Indemnitee shall be deemed to have acted in a manner
“not opposed to the best interests of the Company” as referred to in this Agreement. 
 (i)
“Voting Securities” shall mean any securities of the Company that vote generally in the election of directors. 
 2.
Indemnification. 
 (a) Indemnification of Expenses. The Company shall indemnify Indemnitee to the fullest extent
permitted by law if Indemnitee was or is or becomes a party to or witness or other participant in, or is threatened to be made a party to or witness or other participant in, any Claim by reason of (or arising in part out of) any Indemnifiable Event
against Expenses, including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses. Such payment of Expenses shall be made by the Company as soon as practicable but in any event no later than
five (5) business days after written demand by Indemnitee therefor is presented to the Company. 
 (b)
Change in Control. The Company agrees that if there is a Change in Control of the Company (other than a Change in Control which has been approved by a majority of the Company’s Board of Directors who were directors immediately prior to such
Change in Control), then with respect to all matters thereafter arising concerning the rights of Indemnitee to payments of Expenses and Expense Advances under this Agreement or any other agreement or under the Company’s Certificate of
Incorporation or Bylaws as now or hereafter in effect, Independent Legal Counsel, if desired by Indemnitee, shall be selected by Indemnitee and approved by the Company (which approval shall not be unreasonably withheld). Such counsel, among other
things, shall

  

 3 

 
render its written opinion to the Company and Indemnitee as to whether and to what extent Indemnitee would be permitted to be indemnified under applicable law and the Company agrees to abide by
such opinion. The Company agrees to pay the reasonable fees of the Independent Legal Counsel referred to above and to indemnify fully such counsel against any and all Expenses (including attorneys’ fees), claims, liabilities and damages arising
out of or relating to this Agreement or its engagement pursuant hereto. Notwithstanding any other provision of this Agreement, the Company shall not be required to pay Expenses of more than one Independent Legal Counsel in connection with all
matters concerning a single Indemnitee, and such Independent Legal Counsel shall be the Independent Legal Counsel for any or all other Indemnitees unless (i) the Company otherwise determines or (ii) any Indemnitee shall provide a written
statement setting forth in detail a reasonable objection to such Independent Legal Counsel representing other Indemnitees. 
 (c) Mandatory Payment of Expenses. Notwithstanding any other provision of this Agreement other than Section 9 hereof, to the extent that Indemnitee has been successful on the merits or otherwise,
including, without limitation, the dismissal of an action without prejudice, in defense of any Claim regarding any Indemnifiable Event, Indemnitee shall be indemnified against all Expenses incurred by Indemnitee in connection therewith. 

3. Expenses; Indemnification Procedure. 
 (a) Advancement of Expenses. The Company shall advance all Expenses incurred by Indemnitee. The advances to be made hereunder shall be paid by the Company to Indemnitee as soon as practicable but in any
event no later than 30 days after written demand by Indemnitee therefor to the Company. Indemnitee hereby agrees to repay to the Company all amounts advanced to Indemnitee hereunder if it is ultimately determined that Indemnitee is not entitled to
indemnification hereunder. The Company’s obligation to advance Expenses shall terminate with respect to any Claim as to which the Indemnitee shall have entered a plea of guilty or nolo contendere, or an equivalent plea acknowledging guilt.

 (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a condition precedent to Indemnitee’s right to
be indemnified under this Agreement, give the Company notice in writing as soon as practicable of any Claim made against Indemnitee for which indemnification will or could be sought under this Agreement; provided however that the failure to so
provide notice to the Company shall not relieve the Company from any liability that it may have to Indemnitee hereunder unless the Company’s ability to participate in the defense of such claim was materially and adversely affected by such
failure. Notice to the Company shall be directed to the Chief Executive Officer of the Company at the address shown on the signature page of this Agreement (or such other address as the Company shall designate in writing to Indemnitee). In addition,
Indemnitee shall give the Company such information and cooperation as it may reasonably require and as shall be within Indemnitee’s power, to the extent that doing so is consistent with the exercise of the Indemnitee’s rights under the
federal and state Constitutions. Company shall provide Indemnitee with such information and cooperation as Indemnitee may reasonably require, to the extent that doing so is consistent with the Company’s obligation to cooperate with regulatory
or law enforcement agencies. 
  

 4 

 (c) No Presumptions; Burden of Proof. For purposes of this Agreement, the
termination of any Claim by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that Indemnitee did not meet any particular standard
of conduct or have any particular belief or that a court has determined that indemnification is not permitted by applicable law. 
 (d) Notice to Insurers. If, at the time of the receipt by the Company of a notice of a Claim pursuant to Section 3(b) hereof, the Company has liability insurance in effect which may cover such Claim,
the Company shall give prompt notice of the commencement of such Claim to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers
to pay, on behalf of the Indemnitee, all amounts payable as a result of such Claim in accordance with the terms of such policies. The Company shall keep Indemnitee reasonably informed as to the status of all relevant insurance matters. 

(e) Selection of Counsel. In the event the Company shall be obligated hereunder to pay the Expenses of any Claim the
Company, if appropriate, shall be entitled to assume the defense of such Claim with counsel approved by Indemnitee (not to be unreasonably withheld) upon the delivery to Indemnitee of written notice of the Company’s election so to do. After
delivery of such notice, approval of such counsel by Indemnitee and the retention of such counsel by the Company, the Company will not be liable to Indemnitee under this Agreement for any fees of counsel subsequently incurred by Indemnitee with
respect to the same Claim; provided that, (i) Indemnitee shall have the right to employ Indemnitee’s separate counsel in any such Claim at Indemnitee’s Expense and (ii) if (A) the employment of separate counsel by Indemnitee
has been previously authorized by the Company, (B) Indemnitee shall have reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in the conduct of any such defense, or (C) the Company shall not
continue to retain such counsel to defend such Claim, then the fees and Expenses of Indemnitee’s separate counsel shall be at the Expense of the Company. 
 4. Additional Indemnification Rights; Nonexclusivity; Primacy of Indemnification. 
 (a) Scope. The Company hereby agrees to indemnify the Indemnitee to the fullest extent permitted by law, notwithstanding that such indemnification is not specifically authorized by the other provisions of
this Agreement, the Company’s Certificate of Incorporation, the Company’s Bylaws (as now or hereafter in effect) or by statute. In the event of any change after the date of this Agreement in any applicable law, statute or rule which
expands the right of a Delaware corporation to indemnify a member of its board of directors or an officer, employee, agent or fiduciary, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits
afforded by such change. In the event of any change in any applicable law, statute or rule which narrows

  

 5 

 
the right of a Delaware corporation to indemnify a member of its board of directors or an officer, employee, agent or fiduciary, such change, to the extent not otherwise required by such law,
statute or rule to be applied to this Agreement, shall have no effect on this Agreement or the parties’ rights and obligations hereunder except as set forth in Section 9(a) hereof. 
 (b) Nonexclusivity. The indemnification provided by this Agreement shall be in addition to any rights to which Indemnitee may
be entitled under the Company’s Certificate of Incorporation, its Bylaws (as now hereafter in effect), any other agreement, any vote of stockholders or disinterested directors, the General Corporation Law of the State of Delaware, or otherwise.
The indemnification provided under this Agreement shall continue as to Indemnitee for any action taken or not taken while serving in an indemnified capacity even though Indemnitee may have ceased to serve in such capacity. 
 (c) Primacy of Indemnification. The Company hereby acknowledges that Indemnitee has certain rights to indemnification,
advancement of expenses and/or insurance provided by [Name of Fund/Sponsor] and certain of its affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its
obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to
advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this
Agreement and the Certificate of Incorporation or Bylaws of the Company (or any other agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors, and, (iii) that it irrevocably
waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment
by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to
the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 4(c).

 5. No Duplication of Payments. Except as provided above in Section 4(c), the Company shall not be liable under this
Agreement to make any payment in connection with any Claim made against Indemnitee to the extent Indemnitee has otherwise actually received payment (under any insurance policy, provision of the Company’s Certificate of Incorporation, Bylaw (as
now or hereafter in effect) or otherwise) of the amounts otherwise indemnifiable hereunder. 
 6. Partial Indemnification. If
Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of Expenses incurred in connection with any Claim, but not, however, for all of the total amount thereof, the Company shall
nevertheless indemnify Indemnitee for the portion of such Expenses to which Indemnitee is entitled. 
  

 6 

 7. No Imputation. The knowledge or actions, or failure to act, of any director, officer,
agent or employee of the Company or the Company itself shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 
 8. Liability Insurance. For the duration of Indemnitee’s service as a director or officer or other agent of the Company, and thereafter for so long as Indemnitee shall be subject to any pending or
possible Claim by reason of any Indemnifiable Event, the Company shall use commercially reasonable efforts (taking into account the scope and amount of coverage available relative to the cost thereof) to cause to be maintained in effect policies of
liability insurance providing coverage for directors and officers of the Company that are at least substantially comparable in scope and amount to that provided by the Company’s current policies of directors’ and officers’ liability
insurance. To the extent the Company maintains liability insurance applicable to directors, officers, employees, agents or fiduciaries, Indemnitee shall be covered by such policies in such a manner as to provide Indemnitee the same rights and
benefits as are provided to the most favorably insured of the Company’s directors, if Indemnitee is a director; or of the Company’s officers, if Indemnitee is not a director of the Company but is an officer; or of the Company’s key
employees, agents or fiduciaries, if Indemnitee is not an officer or director but is a key employee, agent or fiduciary. 
 9.
Exceptions. Notwithstanding any other provision of this Agreement, the Company shall not be obligated pursuant to the terms of this Agreement: 
 (a) Excluded Action or Omissions. To indemnify Indemnitee for acts, omissions or transactions if a final decision by a court having jurisdiction in the matter shall determine that such indemnification is
prohibited by applicable law. 
 (b) Claims Initiated by Indemnitee. To indemnify or advance Expenses to
Indemnitee with respect to Claims initiated or brought voluntarily by Indemnitee and not by way of defense, except (i) with respect to actions or proceedings brought to establish or enforce a right to indemnification under this Agreement or any
other agreement or insurance policy or under the Company’s Certificate of Incorporation or Bylaws now or hereafter in effect relating to Claims for Indemnifiable Events, (ii) in specific cases if the Board of Directors has approved the
initiation or bringing of such Claim, or (iii) as otherwise required under Section 145 of the Delaware General Corporation Law, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advance
Expense payment or insurance recovery, as the case may be. 
 (c) Lack of Good Faith. To indemnify Indemnitee for
any Expenses incurred by the Indemnitee with respect to any proceeding instituted by Indemnitee to enforce or interpret this Agreement, if a court of competent jurisdiction determines that each of the material assertions made by the Indemnitee in
such proceeding was not made in good faith or was frivolous. 
  

 7 

 (d) Claims Under Section 16(b). To indemnify Indemnitee for expenses
and the payment of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 16(b) of the Securities Exchange Act of 1934, as amended, or any similar successor statute; provided that the Company shall
advance expenses in connection with Indemnitee’s defense of a claim under Section 16(b), which advances shall be repaid to the Company if it is ultimately determined that Indemnitee is not entitled to indemnification of such expenses.

 10. Period of Limitations. No legal action shall be brought and no cause of action shall be asserted by or in the right of
the Company against Indemnitee, Indemnitee’s estate, spouse, heirs, executors or personal or legal representatives after the expiration of two years from the date of accrual of such cause of action, and any claim or cause of action of the
Company shall be extinguished and deemed released unless asserted by the timely filing of a legal action within such two-year period; provided, however, that if any shorter period of limitations is otherwise applicable to any such cause of action,
such shorter period shall govern. 
 11. Counterparts. This Agreement may be executed in one or more counterparts, each of which
shall constitute an original. 
 12. Binding Effect; Successors and Assigns. This Agreement shall be binding upon and inure to
the benefit of and be enforceable by the parties hereto and their respective successors, assigns (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the
Company), spouses, heirs and personal and legal representatives. The Company shall require and cause any successor (whether direct or indirect, and whether by purchase, merger, consolidation or otherwise) to all, substantially all, or a substantial
part, of the business or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be
required to perform if no such succession had taken place. This Agreement shall continue in effect regardless of whether Indemnitee continues to serve as a director, officer, employee, agent or fiduciary (as applicable) of the Company or of any
other enterprise at the Company’s request. 
 13. Attorneys’ Fees. In the event that any action is instituted by
Indemnitee under this Agreement or under any liability insurance policies maintained by the Company to enforce or interpret any of the terms hereof or thereof, Indemnitee shall be entitled to be paid all Expenses incurred by Indemnitee with respect
to such action, regardless of whether Indemnitee is ultimately successful in such action, and shall be entitled to the advancement of Expenses with respect to such action, unless as a part of such action a court of competent jurisdiction over such
action determines that each of the material assertions made by Indemnitee as a basis for such action was not made in good faith or was frivolous. In the event of an action instituted by or in the name of the Company under this Agreement to enforce
or interpret any of the terms of this Agreement, Indemnitee shall be entitled to be paid all Expenses incurred by Indemnitee in defense of such action (including costs and Expenses incurred with respect to Indemnitee’s counterclaims and
cross-claims made in such action), and shall be entitled to the advancement of Expenses with respect to such action. 
  

 8 

 14. Notice. All notices, requests, demands and other communications under this Agreement
shall be in writing and shall be deemed duly given (i) if delivered by hand and signed for by the party addressed, on the date of such delivery, or (ii) if mailed by domestic certified or registered mail with postage prepaid, on the third
business day after the date postmarked. Addresses for notice to either party are as shown on the signature page of this Agreement, or as subsequently modified by written notice. 
 15. Consent to Jurisdiction. The Company and Indemnitee each hereby irrevocably consent to the jurisdiction of the courts of the State of
Delaware for all purposes in connection with any action or proceeding which arises out of or relates to this Agreement and agree that any action instituted under this Agreement shall be commenced, prosecuted and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be the exclusive and only proper forum for adjudicating such a claim. 
 16. Severability. The provisions of this Agreement shall be severable in the event that any of the provisions hereof (including any provision within a single section, paragraph or sentence) are held by a
court of competent jurisdiction to be invalid, void or otherwise unenforceable, and the remaining provisions shall remain enforceable to the fullest extent permitted by law. Furthermore, to the fullest extent possible, the provisions of this
Agreement (including, without limitations, each portion of this Agreement containing any provision held to be invalid, void or otherwise unenforceable, that is not itself invalid, void or unenforceable) shall be construed so as to give effect to the
intent manifested by the provision held invalid, illegal or unenforceable. 
 17. Choice of Law. This Agreement shall be
governed by and its provisions construed and enforced in accordance with the laws of the State of Delaware as applied to contracts between Delaware residents entered into and to be performed entirely within the State of Delaware. 
 18. Subrogation. In the event of payment under this Agreement, except as provided in Section 4(c) above, the Company shall be
subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all documents required and shall do all acts that may be necessary to secure such rights and to enable the Company effectively to bring suit
to enforce such rights. 
 19. Amendment and Termination. Due to the uncertain application of any statutes of limitations that
may govern any Claim, this Agreement shall be of indefinite duration. No amendment, modification, termination or cancellation of this Agreement shall be effective unless it is in writing signed by both the parties hereto. No waiver of any of the
provisions of this Agreement shall be deemed to be or shall constitute a waiver of any other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver. 
 20. Integration and Entire Agreement. This Agreement sets forth the entire understanding between the parties hereto and supersedes and
merges all previous written and oral negotiations, commitments, understandings and agreements relating to the subject matter hereof between the parties hereto. If the Company and Indemnitee have previously entered into an Indemnification Agreement
providing for indemnification of Indemnitee by the Company, the

  

 9 

 
parties’ entry into this Indemnification Agreement shall be deemed to amend and restate such Indemnification Agreement to read in its entirety as, and to be superseded by, this
Indemnification Agreement. 
 21. No Construction as Employment Agreement. Nothing contained in this Agreement shall be
construed as giving Indemnitee any right to be retained in the employ of the Company or any of its subsidiaries or affiliated entities. 
  

 10 

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