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) (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

 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.

successors, assigns, heirs, executors and administrators of the parties to this Agreement.

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
