Registration Rights

2.1Requested Registration.

(a)Request for Registration. Subject to the conditions set forth in this Section 2.1, if the Company shall receive from Initiating Holders a written request signed by such Initiating Holders that the Company effect any registration with respect to all or a part of the Registrable Securities (such request shall state the number of shares of Registrable Securities to be disposed of and the intended methods of disposition of such shares by such Initiating Holders), the Company will:

(i)promptly give written notice of the proposed registration to all other Holders; and

(ii)as soon as practicable, file and use its commercially reasonable efforts to effect such registration (including, without limitation, filing post-effective amendments, appropriate qualifications under applicable blue sky or other state securities laws, and appropriate compliance with the Securities Act) and to 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 as are specified in a written request received by the Company within twenty (20) days after such written notice from the Company is mailed or delivered.

(b)Limitations on Requested Registration. The Company shall not be obligated to effect, or to take any action to effect, any such registration pursuant to this Section 2.1:

(i)Prior to the earlier of (a) the four (4) year anniversary of the date of the Prior Agreement or (b) one hundred and eighty (180) days following the effective date of the first registration statement filed by the Company covering an underwritten offering of any of its securities to

the general public (or the subsequent date on which all market stand-off agreements applicable to the offering have terminated);

(ii)If the Initiating Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration statement, propose to sell Registrable Securities and such other securities (if any) the aggregate proceeds of which (after deduction for underwriter’s discounts and expenses related to the issuance) are less than $5,000,000;

(iii)In any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, qualification, or compliance, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act;

(iv)After the Company has initiated two (2) such registrations pursuant to this Section 2.1 (counting for these purposes only (x) registrations which have been declared or ordered effective and pursuant to which securities have been sold, and (y) Withdrawn Registrations);

(v)During the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of filing of, and ending on a date one hundred eighty (180) days after the effective date of, a Company-initiated registration (or ending on the subsequent date on which all market stand-off agreements applicable to the offering have terminated); provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective; and

(vi)If the Initiating Holders propose to dispose of shares of Registrable Securities which may be immediately registered on Form S-3 pursuant to a request made under Section 2.3 hereof ; and

(c)Deferral. If (i) in the good faith judgment of the Board of Directors of the Company, the filing of a registration statement covering the Registrable Securities would be materially detrimental to the Company and the Board of Directors of the Company concludes, as a result, that it is in the best interests of the Company to defer the filing of such registration statement at such time, and (ii) the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be materially detrimental to the Company for such registration statement to be filed in the near future and that it is, therefore, in the best interests of the Company to defer the filing of such registration statement, then (in addition to the limitations set forth in Section 2.1(b) (v) above) the Company shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders, and, provided further, that the Company shall not defer its obligation in this manner more than two (2) times in any twelve-month period; provided further that the Company shall not register any securities for the account of itself or any other stockholder during such ninety (90) day period (other than a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating to a corporate reorganization or transaction under Rule 145 of the Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered).

(d)Other Shares. The registration statement filed pursuant to the request of the Initiating Holders may, subject to the provisions of Section 2.1(e), include Other Shares, and may include securities of the Company being sold for the account of the Company.

(e)Underwriting. If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 2.1 and the Company shall include such information in the written notice given pursuant to Section 2.1(a)(i). In such event, the right of any Holder to include all or any portion of its Registrable Securities in a registration pursuant to this Section 2.1 shall be conditioned upon such Holder’s participation in an underwriting and the inclusion of such Holder’s Registrable Securities to the extent provided herein. If the Company shall request inclusion in any registration pursuant to Section 2.1 of securities being sold for its own account, or if other persons shall request inclusion in any registration pursuant to Section 2.1, the Initiating Holders shall, on behalf of all Holders, offer to include such securities in the underwriting and such offer shall be conditioned upon the participation of the Company or such other persons in such underwriting and the inclusion of the Company’s and such person’s other securities of the Company and their acceptance of the further applicable provisions of this Section 2 (including Section 2.10). The Company shall (together with all Holders and other persons proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting by the Initiating Holders holding a majority of the Registrable Securities held by such Initiating Holders, which underwriters are reasonably acceptable to the Company.

Notwithstanding any other provision of this Section 2.1, if the underwriters advise the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, the number of Registrable Securities and Other Shares that may be so included shall be allocated as follows: (i) first, among all Holders requesting to include Registrable Securities in such registration statement based on the pro rata percentage of Registrable Securities held by such Holders, assuming conversion; and (ii) second, to the Company, which the Company may allocate, at its discretion, for its own account, or for the account of other holders or employees of the Company; provided, however, that such allocation shall not operate to reduce the aggregate number of Registrable Securities to be included in such registration, if any Holder does not request inclusion of the maximum number of shares of Registrable Securities allocated to it pursuant to its pro rata allocation, in which case the remaining portion of its allocation shall be reallocated among those requesting Holders whose allocations did not satisfy their initial requests, pro rata, on the basis of the number of shares of Registrable Securities held by such Holders on an as-converted to Common Stock basis, and this procedure shall be repeated until all of the shares of Registrable Securities which may be included in the registration on behalf of the Holders have been so allocated. In no event shall the number of Registrable Securities underwritten in such registration be limited unless and until all shares held by persons other than Holders, including the Company, are completely excluded from such offering.

If a person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such person shall be excluded therefrom by written notice from the Company, the underwriter or the Initiating Holders. The securities so excluded shall also be withdrawn from registration. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall also be withdrawn from such registration. If shares are so withdrawn from the registration and if the number of shares to be included in such registration was previously reduced as a result of marketing factors pursuant to this Section 2.1(e), then the Company shall then offer to all Holders who have retained rights to include securities in the registration the right to include additional Registrable Securities in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be allocated among such Holders requesting additional inclusion, as set forth above.

2.2Company Registration

(a)Company Registration. If the Company shall determine to register any of its securities either for its own account or the account of a security holder or holders, other than a registration pursuant to Section 2.1 or 2.3, a registration relating solely to employee benefit plans, a registration relating to the offer and sale of debt securities, a registration relating to a corporate reorganization or other Rule 145 transaction, or a registration on any registration form that does not permit secondary sales, the Company will:

(i)promptly give written notice of the proposed registration to all Holders; and

(ii)use its commercially reasonable efforts to include in such registration (and any related qualification under blue sky laws or other compliance), except as set forth in Section 2.2(b) below, and in any underwriting involved therein, all of such Registrable Securities as are specified in a written request or requests made by any Holder or Holders received by the Company within fifteen (15) days after such written notice from the Company is mailed or delivered. Such written request may specify all or a part of a Holder’s Registrable Securities.

(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 2.2(a) (i). In such event, the right of any Holder to registration pursuant to this Section 2.2 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company, the Other Selling Stockholders and other holders of securities of the Company with registration rights to participate therein distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by the Company.

(A)Notwithstanding any other provision of this Section 2.2, if the underwriters advise the Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the underwriters may (subject to the limitations set forth below) limit the number of Registrable Securities to be included in, the registration and underwriting. The Company shall so advise all holders of securities requesting registration, and the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated, as follows: (i) first, to the Company for securities being sold for its own account, (ii) second, to the Holders requesting to include Registrable Securities in such registration statement based on the pro rata percentage of Registrable Securities held by such Holders, on an as-converted to Common Stock basis and (iii) third, to the Other Selling Stockholders requesting to include Other Shares in such registration statement based on the pro rata percentage of Other Shares held by such Other Selling Stockholders, assuming conversion; provided, however, that such allocation shall not operate to reduce the aggregate number of Registrable Securities to be included in such registration, if any Holder does not request inclusion of the maximum number of shares of Registrable Securities allocated to it pursuant to its pro rata allocation, in which case the remaining portion of its allocation shall be reallocated among those requesting Holders whose allocations did not satisfy their initial requests, pro rata, on the basis of the number of shares of Registrable Securities held by such Holders assuming conversion, and this procedure shall be repeated until all of the shares of Registrable Securities which may be included in the registration on behalf of the Holders have been so allocated. In no event shall the number of Registrable Securities underwritten in such registration be limited unless and until all shares held by persons other than Holders (excluding shares registered for the

account of the Company) are completely excluded from such offering. Notwithstanding the foregoing, no such reduction shall reduce the value of the Registrable Securities of the Holders included in such registration below thirty percent (30%) of the total value of securities included in such registration, unless such offering is the Company’s Initial Public Offering and such registration does not include shares of any other selling stockholders (excluding shares registered for the account of the Company), in which event any or all of the Registrable Securities of the Holders may be excluded.

If a person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such person shall also be excluded therefrom by written notice from the Company or the underwriter. The Registrable Securities or other securities so excluded shall also be withdrawn from such registration. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration.

(c)Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration.

2.3Registration on Form S-3

(a)Request for Form S-3 Registration. After its Initial Public Offering, the Company shall use its commercially reasonable efforts to qualify for registration on Form S-3 or any comparable or successor form or forms. After the Company has qualified for the use of Form S-3 or any comparable or successor form or forms, in addition to the rights contained in the foregoing provisions of this Section 2 and subject to the conditions set forth in this Section 2.3, if the Company shall receive from a Holder or Holders of at least 10% of the Registrable Securities a written request that the Company effect any registration on Form S-3 or any similar short form registration statement with respect to all or part of the Registrable Securities (such request shall state the number of shares of Registrable Securities to be disposed of and the intended methods of disposition of such shares by such Holder or Holders), the Company will take all such action with respect to such Registrable Securities as required by Section 2.1(a)(i) and (ii).

(b)Limitations on Form S-3 Registration. The Company shall not be obligated to effect, or take any action to effect, any such registration pursuant to this Section 2.3:

(i)In the circumstances described in either Sections 2.1(b) (i), 2.1(b) (iii) or 2.1(b) (v);

(ii)If the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) on Form S-3 at an aggregate price to the public of less than $1,000,000; or

(iii)If, in a given twelve-month period, the Company has effected two (2) such registrations in such period.

(c)Deferral. The provisions of Section 2.1(c) shall apply to any registration pursuant to this Section 2.3.

(d)Underwriting. If the Holders of Registrable Securities requesting registration under this Section 2.3 intend to distribute the Registrable Securities covered by their request by means of an underwriting, the provisions of Section 2.1(e) shall apply to such registration. Notwithstanding anything contained herein to the contrary, registrations effected pursuant to this Section 2.3 shall not be counted as requests for registration or registrations effected pursuant to Section 2.1.

2.4Expenses of Registration. All Registration Expenses incurred in connection with registrations pursuant to Sections 2.1, 2.2 and 2.3 hereof shall be borne by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Sections 2.1 and 2.3 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered or because a sufficient number of Holders shall have withdrawn so that the minimum offering conditions set forth in Sections 2.1 and 2.3 are no longer satisfied (in which case all participating Holders shall bear such expenses pro rata among each other based on the number of Registrable Securities requested to be so registered), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to a demand registration pursuant to Section 2.1;

2.5Registration Procedures. In the case of each registration effected by the Company pursuant to Section 2, the Company will keep each Holder advised in writing as to the initiation of each registration and as to the completion thereof. At its expense, the Company will use its commercially reasonable efforts to:

(a)Keep such registration effective for a period of ending on the earlier of the date which is sixty (60) days from the effective date of the registration statement or such time as the Holder or Holders have completed the distribution described in the registration statement relating thereto;

(b)Prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in subsection (a) above;

(e)Notify each seller of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act 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 or incomplete in light of the circumstances then existing, and following such notification promptly prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or incomplete in light of the circumstances then existing;

(f)Provide a transfer agent and registrar for all Registrable Securities registered pursuant to such registration statement and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration;

(g)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

(h)In connection with any underwritten offering pursuant to a registration statement filed pursuant to Section 2.1 hereof, enter into an underwriting agreement in form reasonably necessary to effect the offer and sale of Common Stock, provided such underwriting agreement contains reasonable and customary provisions, and provided further, that each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement.

2.6Indemnification.

(a)To the extent permitted by law, the Company will indemnify and hold harmless each Holder, each of its officers, directors and partners, legal counsel and accountants and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance has been effected pursuant to this Section 2, and each underwriter, if any, and each person who controls within the meaning of Section 15 of the Securities Act any underwriter, against all expenses, claims, losses, damages and liabilities (or actions, proceedings or settlements in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact contained or incorporated by reference in any registration statement, any prospectus included in the registration statement, any issuer free writing prospectus (as defined in Rule 433 of the Securities Act), any issuer information (as defined in Rule 433 of the Securities Act) filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any other document incident to any such registration, qualification or compliance prepared by or on behalf of the Company or used or referred to by the Company, (ii) 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 (iii) any violation (or alleged violation) by the Company of the Securities Act, any state securities laws or any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any offering covered by such registration, qualification or compliance, and the Company will reimburse each such Holder, each of its officers, directors, partners, legal counsel and accountants and each person controlling such Holder, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending or settling 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 action arises out of or is based on any untrue statement or omission based upon written information furnished to the Company by such Holder, any of such Holder’s officers, directors, partners, legal counsel or accountants, any person controlling such Holder, such underwriter or any person who controls any such underwriter, and stated to be specifically for use therein; and provided, further that, the indemnity agreement contained in this Section 2.6(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld).

(b)To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification or compliance is being effected, indemnify and hold harmless the Company, each of its directors, officers, partners, legal counsel and accountants and each underwriter, if any, of the Company’s securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, each other such Holder, and each of their officers, directors and partners, and each person controlling each other such Holder, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact contained or incorporated by reference in any prospectus, offering circular or

(c)Each party entitled to indemnification under this Section 2.6 (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 such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld), and the Indemnified Party may participate in such defense at such party’s expense; and 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 Section 2.6, to the extent such failure is not prejudicial. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that 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. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom.

(d)If the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage, or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. No person or entity will be required under this Section 2.6 to contribute any amount in excess of the net proceeds from the offering received by such person or entity, except in the case of fraud or willful misconduct by such person or entity. No person or entity guilty of fraudulent misrepresentation (within

the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO (1) RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD IN THE EVENT OF AN INITIAL PUBLIC OFFERING, AS SET FORTH IN AN INVESTORS’ RIGHTS AGREEMENT, AND (2) VOTING RESTRICTIONS AS SET FORTH IN A VOTING AGREEMENT AMONG THE COMPANY AND THE ORIGINAL HOLDERS OF THESE SHARES, COPIES OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY.

The Holders consent to the Company making a notation on its records and giving instructions to any transfer agent of the Restricted Securities in order to implement the restrictions on transfer established in this Section 2.8.

(d)The first legend referring to federal and state securities laws identified in Section 2.8(c) hereof stamped on a certificate evidencing the Restricted Securities and the stock transfer instructions and record notations with respect to such Restricted Securities shall be removed and the Company shall issue a certificate without such legend to the holder of such Restricted Securities if (i) such securities are registered under the Securities Act, (ii) such holder provides the Company with an opinion of counsel reasonably acceptable to the Company to the effect that a public sale or transfer of such securities may be made without registration under the Securities Act, or (iii) such holder provides the Company with reasonable assurances, that such securities can be sold pursuant to Rule 144 under the Securities Act.

2.9Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Restricted Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to:

(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 at any time after it has become subject to such reporting requirements; and

(c)So long as a Holder owns any Restricted Securities, furnish to the Holder forthwith upon written request a written statement by the Company as to its compliance with the reporting requirements of Rule 144 (at any time from and after ninety (90) days following the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any such securities without registration.

2.10Market Stand-Off Agreement. If requested by the Company and an underwriter of Common Stock (or other securities) of the Company, each Holder shall not sell or otherwise transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any Common Stock (or other securities) of the Company held by such Holder (other than those included in the registration) during the one hundred and eighty (180) day period following the effective date of the registration statement for the Company’s Initial Public Offering filed under the Securities Act (or such other period as may be requested by the Company or an underwriter to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto, including without limitation any rules established by FINRA) (the “Lockup Period”); provided that each such Holder shall not be obligated to comply with the terms of this Section 2.10 unless and until all of the Company’s (i) officers, (ii) directors and (iii) stockholders holding greater than one percent (1%) of the outstanding capital stock agree in writing to also be bound by the terms of this Section 2.10. The obligations described in this Section 2.10 shall not apply to a registration relating solely to employee benefit plans on Form S-l or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future.

2.11Delay of Registration. No Holder shall have any right to take any action to restrain, enjoin, or otherwise delay any registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2.

2.13Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of any three of the four largest holders of the Company’s outstanding Preferred Stock on an as converted to Common Stock basis (aggregating for purposes of calculating the four largest holders any shares held by affiliated entities (including, without limitation, affiliated venture capital funds)) (any such group of three holders, a “Requisite Majority”), enter into any agreement with any holder or prospective holder of any securities of the Company giving such holder or prospective holder any registration rights the terms of which are pari passu with or senior to the registration rights granted to the Holders hereunder; provided, however, Affiliated Transfers shall not be subject to any minimum threshold requirements.

2.14Series D and D Prime Conversion Price Adjustment.

(a)In the event that an adjustment in the Series D IPO Conversion Ratio would be required pursuant to Section 4.4(h) of the Certificate of Incorporation in connection with a Qualified Public Offering, the Company may instead, in the sole discretion of a majority of the Company’s Board of Directors (not including any director appointed by the holders of the Series D Preferred Stock), elect to pay to the holders of Series D Preferred Stock, in respect of each share of Series D Preferred Stock that is converted into Common Stock in connection with such Qualified Public Offering, a per share amount in cash equal to the difference between (i) the Series D IPO Threshold, minus (ii) the IPO Price (such amount, the “Series D Cash Adjustment” and such election, a “Series D Company Election”)); provided, however, that if the Series D Cash Adjustment would exceed the Conversion Price of the Series D Preferred Stock, then the Series D Cash Adjustment will reduced to the Conversion Price of the Series D Preferred Stock, and the Company’s payment of such reduced amount will be in full satisfaction of the Series D Cash Adjustment and any adjusted to the Series D IPO Conversion Ratio.

(b)In the event that an adjustment in the Series D Prime IPO Conversion Ratio would be required pursuant to Section 4.4(h) of the Certificate of Incorporation in connection with a Qualified Public Offering, the Company may instead, in the sole discretion of a majority of the Company’s Board of Directors (not including any director appointed by the holders of the Series D Prime Preferred Stock), elect to pay to the holders of Series D Prime Preferred Stock, in respect of each share of Series D Prime Preferred Stock that is converted into Common Stock in connection with such Qualified Public Offering, a per share amount in cash equal to the difference between (i) the Series D Prime IPO Threshold, and (ii) the IPO Price (such amount, the “Series D Prime Cash Adjustment” and such election, a “Series D Prime Company Election” (and together with the Series D Company Election, a “Company Election”)); provided, however, that if the Series D Prime Cash Adjustment would exceed the Conversion Price of the Series D Prime Preferred Stock, then the Series D Prime Cash Adjustment will reduced to the Conversion Price of the Series D Prime Preferred Stock, and the Company’s payment of such reduced amount will be in full satisfaction of the Series D Prime Cash Adjustment and any adjustment to the Series D Prime IPO Conversion Ratio.

(c)A Company Election must be made no later than the day on which the Company’s registration statement for such Qualified Public Offering is declared effective, in which case the Company Election will be deemed to occur immediately prior to the conversion of the Series D Preferred Stock and Series D Prime Preferred Stock into Common Stock in accordance with the Certificate of Incorporation. If the Company makes a Company Election prior to the day on which the Company’s registration statement for such Qualified Public Offering is declared effective, then the Company may revoke such Company Election at any time prior to the Qualified Public Offering, in which case the adjustment in the Series D IPO Conversion Ratio and/or Series D Prime IPO Conversion Ratio will be made as otherwise required by Section 4.4(h) of the Certificate of Incorporation. If the Company makes a Company Election, and such Company Election is not revoked, then the Series D Cash

Adjustment and/or Series D Prime Cash Adjustment shall be paid in full no later than fifteen (15) business days following the effectiveness of the Company’s registration statement for such Qualified Public Offering.

(d)The Company may, in the sole discretion of a majority of the Company’s Board of Directors (not including any director appointed by the holders of the Series D Prime Preferred Stock), make a partial Company Election, in which case the Series D IPO Conversion Ratio and Series D Prime IPO Conversion Ratio will be satisfied partly in cash and partly in shares of Common Stock as set forth in this paragraph. When making a Company Election, the Company will specify the percentage of the Series D Company Election and/or Series D Prime Company Election that will be paid in cash (the “Election Percentage”) (the Election Percentage may be different for the Series D Company Election and the Series D Prime Company Election). As a result of a partial Company Election:

(i)the Company will pay an amount in cash equal to (A) the applicable Election Percentage times (B) the Series D Cash Adjustment and Series D Prime Cash Adjustment (as applicable), and

(ii)the Company will reduce the Series D IPO Conversion Ratio and Series D Prime IPO Conversion Ratio by an amount equal to (x) the applicable Election Percentage times (y) the Series D IPO Conversion Ratio and Series D Prime IPO Conversion Ratio (as applicable) minus 1.00.

For example, if the IPO Price is $9.00, then the Series D Cash Adjustment would be $1.1845 per share, the Series D Prime Cash Adjustment would be $3.0543 per share, the Series D IPO Conversion Ratio would be 1.13-to-1.00, and the Series D Prime IPO Conversion Ratio would be 1.34-to-1.00. If the Election Percentage is 40% (meaning that 40% will be satisfied in cash), then the Series D Cash Adjustment would be 40% of $1.1845 (which is $0.4738 per share), the Series D Prime Cash Adjustment would be 40% of $3.0543 (which is $1.2217 per share), the Series D IPO Conversion Ratio would be reduced by 40% of 0.13 (which is 0.05, which results in a ratio of 1.08-to-1.00), and the Series D Prime IPO Conversion Ratio would be reduced by 40% of 0.34 (which is 0.14, which results in a ratio of 1.20-to-1.00).

(e)As used in this Section 2.14, the terms “Conversion Price”, “IPO Price”, “Series D IPO Conversion Ratio”, “Series D Prime IPO Conversion Ratio”, “Series D IPO Threshold”, and “Series D Prime IPO Threshold” shall have the meanings ascribed to such terms in the Certificate of Incorporation.

2.15Termination of Registration Rights. The right of any Holder to request registration or inclusion in any registration pursuant to Sections 2.1, 2.2 or 2.3 shall terminate on the earlier of (i) such date, on or after the closing of the Company’s first registered public offering of Common Stock, on which all shares of Registrable Securities held or entitled to be held upon conversion by such Holder may immediately be sold under Rule 144 during any ninety (90) day period and (ii) five (5) years after the closing of the Company’s Initial Public Offering.

The Company hereby grants to each Holder who owns at least 1,000,000 Shares or Conversion Stock (as presently constituted and subject to subsequent adjustments for stock splits, stock dividends, reverse stock splits and the like) (the “Significant Holders”), the right of first refusal to purchase its pro rata share of New Securities (as defined in this Section 4.1(a)) which the Company may, from time to time, propose to sell and issue after the date of this Agreement. A Significant Holder’s pro rata share, for purposes of this right of first refusal, is equal to the ratio of (a) the number of shares of Common Stock owned by such Significant Holder immediately prior to the issuance of New Securities (assuming full conversion of the Shares and exercise of all outstanding convertible securities, rights, options and warrants, directly or indirectly, into

Common Stock held by said Significant Holder) to (b) the total number of shares of Common Stock outstanding immediately prior to the issuance of New Securities (assuming full conversion of the Shares and exercise of all outstanding convertible securities, rights, options and warrants, directly or indirectly). This right of first refusal shall be subject to the following provisions:

(a)“New Securities” shall mean any capital stock (including Common Stock and/or Preferred Stock) of the Company whether now authorized or not, and rights, convertible securities, options or warrants to purchase such capital stock, and securities of any type whatsoever that are, or may become, exercisable or convertible into capital stock; provided that the term “New Securities” does not include any shares of Common Stock that are excluded from the definition “Additional Shares of Common” in the Company’s current Eighth Amended and Restated Certificate of Incorporation, as may be amended (the “Certificate of Incorporation”).

(b)If the Company proposes to undertake an issuance of New Securities, it shall give each Significant Holder written notice of its intention, describing the type of New Securities, and their price and the general terms upon which the Company proposes to issue the same. Each Significant Holder shall have fifteen (15) days after receipt of any such notice to agree to purchase such Holder’s pro rata share of such New Securities for the price and upon the terms specified in the notice by giving written notice to the Company, in substantially the form attached hereto as Schedule 1, and stating therein the quantity of New Securities to be purchased. At the expiration of such fifteen (15) day period, the Company shall promptly, in writing, notify each Significant Holder that elects to purchase all the shares available to it (a “Fully-Exercising Holder”) of any other Significant Holder’s failure to do likewise. During the ten (10) calendar day period commencing after the Company has given such notice to the Fully-Exercising Holder, each Fully-Exercising Holder may elect to purchase that portion of the New Securities for which Significant Holders were entitled to subscribe, but which were not subscribed for by the Significant Holders.

(c)If the Significant Holders fail to exercise fully the right of first refusal pursuant to Section 4.1(b) above, the Company shall have thirty (30) 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) to sell that portion of the New Securities with respect to which the Significant Holders’ right of first refusal option set forth in this Section 4.1 was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice to Significant Holders delivered pursuant to Section 4.1(b). If the Company has not sold within such thirty (30) day period, or such sixty (60) day period following the date of said agreement, the Company shall not thereafter issue or sell any New Securities, without first again offering such securities to the Significant Holders in the manner provided in this Section 4.1.

(d)The right of first refusal granted under this Agreement shall expire upon, and shall not be applicable to the first to occur of (i) a Qualified Initial Public Offering, or (ii) five years from the date of the Prior Agreement.
