2.Agreements Among the Company, the Holders and the Common Holders.

2.1Rights of Refusal.

(a)Transfer Notice. If at any time a Common Holder proposes to Transfer Equity Securities (a “Selling Common Holder”), then the Selling Common Holder shall promptly give the Company and each Holder written notice of the Selling Common Holder’s

2

intention to make the Transfer (the “Transfer Notice”). The Transfer Notice shall include (i) a description of the Equity Securities to be Transferred (the “Offered Shares”), (ii) the name(s) and address(es) of the prospective transferee(s), (iii) the purchase price and form of consideration proposed to be paid for the Offered Shares and (iv) the other material terms and conditions upon which the proposed Transfer is to be made. The Transfer Notice shall certify that the Selling Common Holder has received a firm offer from the prospective transferee(s) and in good faith believes a binding agreement for the Transfer is obtainable on the terms set forth in the Transfer Notice. The Transfer Notice shall also include a copy of any written proposal, term sheet or letter of intent or other agreement relating to the proposed Transfer. In the event that the transfer is being made pursuant to the provisions of Section 2.4, the Transfer Notice shall state under which specific clause of Section 2.4 the Transfer is being made.

(b)Company’s Right of First Refusal. The Company shall have an option for a period of [***] from Delivery of the Transfer Notice to elect to purchase the Offered Shares at the same price and subject to the same material terms and conditions as described in the Transfer Notice. The Company may exercise such purchase option and purchase all or any portion of the Offered Shares by notifying the Selling Common Holder in writing before expiration of such [ten (10) day] period as to the number of such shares that it wishes to purchase. If the Company gives the Selling Common Holder notice that it desires to purchase such shares, then payment for the Offered Shares shall be made by check or wire transfer against delivery of the Offered Shares to be purchased at a time and place agreed upon between the parties, which time shall be no later than [***] after Delivery to the Company of the Transfer Notice, unless the Transfer Notice contemplated a later closing with the prospective third-party transferee(s) or unless the value of the consideration to be paid for the Offered Shares has not yet been established pursuant to Section 2.1(e)(ii). If the Company fails to purchase any or all of the Offered Shares by exercising the option granted in this Section 2.1(b) within the period provided, the remaining Offered Shares shall be subject to the options granted to the Holders pursuant to Section 2.1(c)-(d).

(c)Additional Transfer Notice. Subject to the Company’s option set forth in Section 2.1(b), if at any time the Selling Common Holder proposes a Transfer, then, within [***] after the Company has declined to purchase all, or a portion, of the Offered Shares or the Company’s option to so purchase the Offered Shares has expired, the Selling Common Holder shall give each Holder an “Additional Transfer Notice” that shall include all of the information and certifications required in a Transfer Notice and shall additionally identify the Offered Shares that the Company has declined to purchase (the “Remaining Shares”) and reference the Holders’ rights of first refusal and co-sale rights with respect to the proposed Transfer contained in this Agreement.

(d)Holders’ Right of First Refusal.

(i)Each Holder shall have an option for a period of [***] from the Delivery of the Additional Transfer Notice from the Selling Common Holder set forth in Section 2.1(c) to elect to purchase its respective pro rata share of the Remaining Shares at the same price and subject to the same material terms and conditions as described in the Additional Transfer Notice. Each Holder may exercise such purchase option and purchase all or any portion of its pro rata share of the Remaining Shares (a “Participating Holder” for the purposes of this Section 2.1(d) and Section 2.1(e)), by notifying the Selling Common Holder and the Company in writing, before expiration of the [***] period as to the number of such shares that it wishes to purchase (the “Participating Holder Notice”). Each Holder’s pro rata share of the Remaining Shares shall be a fraction of the Remaining Shares, the numerator of which shall be the number of shares of Common Stock (including shares of Common Stock issuable upon conversion of Preferred Shares) owned by such Holder on the date of the Transfer Notice and denominator of which shall be the total number of shares of Common Stock (including shares of Common Stock

3

issuable upon conversion of Preferred Shares) held by all Holders on the date of the Transfer Notice.

(ii)In the event any Holder elects not to purchase its pro rata share of the Remaining Shares available pursuant to its option under Section 2.1(d)(i) within the time period set forth therein, then the Selling Common Holder shall promptly give written notice (the “Overallotment Notice”) to each Participating Holder that has elected to purchase all of its pro rata share of the Remaining Shares (each a “Fully Participating Holder”), which notice shall set forth the number of Remaining Shares not purchased by the other Holders (“Unsubscribed Shares”), and shall offer the Fully Participating Holders the right to acquire the Unsubscribed Shares. Each Fully Participating Holder shall have [***] after Delivery of the Overallotment Notice to deliver a written notice to the Selling Common Holder (the “Participating Holders Overallotment Notice”) of its election to purchase its pro rata share of the Unsubscribed Shares on the same terms and conditions as set forth in the Additional Transfer Notice, which such Participating Holders Overallotment Notice shall also indicate the maximum number of the Unsubscribed Shares that such Fully Participating Holder will purchase in the event that any other Fully Participating Holder elects not to purchase its pro rata share of the Unsubscribed Shares. For the purposes of determining a Fully Participating Holder’s pro rata share of the Unsubscribed Shares under this Section 2.1(d)(ii), the numerator shall be the same as that used in Section 2.1(d)(i) above and the denominator shall be the total number of shares of Common Stock (including shares of Common Stock issuable upon conversion of Preferred Shares) owned by all Fully Participating Holders on the date of the Transfer Notice.

(iii)Each Participating Holder shall be entitled to apportion Remaining Shares to be purchased among its partners and Affiliates, provided that such Participating Holder notifies the Selling Common Holder of such allocation.

(e)Payment.

(i)The Participating Holders shall effect the purchase of the Remaining Shares with payment by check or wire transfer against delivery of the Remaining Shares to be purchased at a time and place agreed upon between the parties, which time shall be no later than [***] after Delivery to the Company of the Transfer Notice, unless the Transfer Notice contemplated a later closing with the prospective third-party transferee(s) or unless the value of the consideration to be paid for the Offered Shares has not yet been established pursuant to Section 2.1(e)(ii).

(ii)Should the purchase price specified in the Transfer Notice or Additional Transfer Notice be payable in a form of consideration other than cash or evidences of indebtedness, the Company (and the Participating Holders) shall have the right to pay such purchase price in an amount of cash equal to the fair market value of such consideration. If the Selling Common Holder and the Company (or the Participating Holders) cannot agree on such fair market value within [***] after Delivery to the Company of the Transfer Notice (or the Delivery of the Additional Transfer Notice to the Holders), the valuation shall be made by an appraiser of recognized standing selected by the Selling Common Holder and the Company (or [***] of the Participating Holders) or, if they cannot agree on an appraiser within [***] after Delivery to the Company of the Transfer Notice (or the Delivery of the Additional Transfer Notice to the Holders), each shall select an appraiser of recognized standing and those appraisers shall designate a third appraiser of recognized standing, whose appraisal shall be determinative of such value. The cost of such appraisal shall be shared equally by the Selling Common Holder, on the one hand, and the Company (and, to the extent there are any, the Participating Holders, on the other hand, with that half of the cost to be borne by the Company and the Participating Holders to be apportioned on a pro rata basis based on the number of shares each such party has expressed an interest in purchasing pursuant to this Section 2). If the time for the closing of the

4

Company’s purchase or the Participating Holders’ purchase has expired but the determination of the value of the purchase price offered by the prospective transferee(s) has not been finalized, then such closing shall be held on or prior to the [***] after such valuation shall have been made pursuant to this Section 2.1(e)(ii).

2.2Right of Co-Sale.

(a)To the extent the Company and the Holders do not exercise their respective rights of refusal as to all of the Offered Shares pursuant to Section 2.1, then each Holder (a “Selling Holder” for purposes of this Section 2.2 and Section 2.6) that notifies the Selling Common Holder in writing within [***] after Delivery of the Additional Transfer Notice referred to in Section 2.1(c) shall have the right to participate in such sale of Equity Securities on the same terms and conditions as specified in the Transfer Notice. Such Selling Holder’s notice to the Selling Common Holder shall indicate the number of shares of capital stock of the Company that the Selling Holder desires to sell. To the extent one or more Selling Holders exercise such right of participation in accordance with the terms and conditions of this Section 2.2, the number of shares of Equity Securities that the Selling Common Holder may sell in the Transfer shall be correspondingly reduced.

(b)Each Selling Holder may sell all or any part of that number of shares of Common Stock (or capital stock of the Company convertible into such number of shares of Common Stock) equal in the aggregate to the product obtained by multiplying (i) the aggregate number of shares of Equity Securities covered by the Transfer Notice that have not been subscribed for pursuant to Section 2.1 by (ii) a fraction, the numerator of which is the number of shares of Common Stock (including shares of Common Stock issuable upon conversion of Preferred Shares) owned by such Selling Holder on the date of the Transfer Notice and the denominator of which is the total number of shares of Common Stock (including shares of Common Stock issuable upon conversion of Preferred Shares) owned by the Selling Common Holder and all of the Selling Holders on the date of the Transfer Notice.

(c)Each Selling Holder shall effect its participation in the sale by promptly delivering to the Selling Common Holder for transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, which represent:

(i)the number of shares of Common Stock that such Selling Holder elects to sell; or

(ii)that number of shares of capital stock of the Company that are at such time convertible into the number of shares of Common Stock that such Selling Holder elects to sell; provided, however, that if the prospective third-party purchaser objects to the delivery of shares of capital stock of the Company other than Common Stock, such Selling Holder shall convert such shares of capital stock of the Company into Common Stock and deliver Common Stock as provided in this Section 2.2. The Company agrees to make any such conversion concurrent with the actual transfer of such shares to the purchaser and contingent on such transfer.

(d)The stock certificate or certificates that each Selling Holder delivers to the Selling Common Holder pursuant to Section 2.2(c) shall be transferred to the prospective purchaser in consummation of the sale of the Equity Securities pursuant to the terms and conditions specified in the Transfer Notice, and such Selling Common Holder shall concurrently therewith remit to such Selling Holder that portion of the sale proceeds to which such Selling Holder is entitled by reason of its participation in such sale. To the extent that any prospective purchaser or purchasers prohibits such assignment or otherwise refuses to purchase shares or other securities from a Selling Holder exercising its rights of co-sale hereunder, the

5

Selling Common Holder shall not sell to such prospective purchaser or purchasers any Equity Securities unless and until, simultaneously with such sale, the Selling Common Holder shall purchase such shares or other securities from such Selling Holder for the same consideration and on the same terms and conditions as the proposed transfer described in the Transfer Notice.

2.3Non-Exercise of Rights. To the extent that the Company and the Holders have not exercised their rights to purchase the Offered Shares or the Remaining Shares within the time periods specified in Section 2.1 and the Holders have not exercised their rights to participate in the sale of the Remaining Shares within the time periods specified in Section 2.2, the Selling Common Holder shall have a period of [***] from the expiration of such rights in which to sell the Offered Shares or the Remaining Shares, as the case may be, upon terms and conditions (including the purchase price) no more favorable than those specified in the Transfer Notice, to the third-party transferee(s) identified in the Transfer Notice. The Company’s first refusal rights and the Holders’ first refusal rights and co-sale rights shall continue to be applicable to any subsequent disposition of the Offered Shares or the Remaining Shares acquired by the third-party transferee(s) until such rights lapse in accordance with the terms of this Agreement. In the event the Selling Common Holder does not consummate the sale or disposition of the Offered Shares and Remaining Shares within the [***] period from the expiration of these rights, the Company’s first refusal rights and the Holders’ first refusal rights and co-sale rights shall continue to be applicable to any subsequent disposition of the Offered Shares or the Remaining Shares by the Selling Common Holder until such rights lapse in accordance with the terms of this Agreement. Furthermore, the exercise or non-exercise of the rights of the Company and the Holders under this Section 2 to purchase Equity Securities from the Selling Common Holder or participate in sales of Equity Securities by the Selling Common Holder shall not adversely affect their rights to make subsequent purchases from the Selling Common Holder of Equity Securities or subsequently participate in sales of Equity Securities by the Selling Common Holder.

2.4Limitations to Rights of Refusal and Co-Sale. Notwithstanding the provisions of Sections 2.1 and 2.2 of this Agreement, the first refusal rights of the Company and first refusal and co-sale rights of the Holders shall not apply to (i) the Transfer of Equity Securities by a Common Holder for estate planning purposes, either during such Common Holder’s lifetime or on death by will or intestacy to such Common Holder’s spouse or other member of a Common Holder’s immediate family, or to a custodian, trustee (including a trustee of a voting trust), executor or other fiduciary for the account of the Common Holder’s spouse or members of the Common Holder’s immediate family, or to a trust for the Common Holder’s own self, or a charitable remainder trust, (ii) a repurchase of Equity Securities from a Common Holder by the Company at cost and pursuant to an agreement containing vesting and/or repurchase provisions, (iii) any sale of Equity Securities pursuant to the exercise of the bring-along right set forth in Section 4.6 of that certain Second Amended and Restated Investors’ Rights Agreement of even date herewith by and among the Company and the other parties thereto, as may be amended from time to time, (iv) any sale of Equity Securities to the public pursuant to a registration statement filed with, and declared effective by, the Securities and Exchange Commission under the Securities Act of 1933, as amended, (v) any pledge of Equity Securities held by a Common Holder made pursuant to a bona fide loan transaction that creates a mere security interest or (vi) any bona fide gift to any charitable organization described in Section 501(c)(3) of the Internal Revenue Code; provided, however, that in the event of any transfer made pursuant to one of the exemptions provided by clause(s) (i) or (vi), (A) the Common Holder shall inform the Holders of such Transfer prior to effecting it and (B) each such transferee or assignee, prior to the completion of the Transfer, shall have executed documents assuming the obligations of Common Holder under this Agreement with respect to the transferred Equity Securities. Such transferred Equity Securities shall remain “Equity Securities” hereunder, and such pledgee, transferee or donee shall be treated as a “Common Holder” for purposes of this Agreement.

(c)In the event of a Prohibited Transfer, each Holder shall have the right to sell to the Common Holder making such Prohibited Transfer the type and number of shares of Equity Securities equal to the number of shares each Holder would have been entitled to transfer to the third-party transferee(s) under Section 2.2 hereof had the Prohibited Transfer been effected pursuant to and in compliance with the terms hereof. Such sale shall be made on the following terms and conditions:

(i)The price per share at which the shares are to be sold to the Common Holder shall be equal to the price per share paid by the third-party transferee(s) to the Common Holder in the Prohibited Transfer. The Common Holder shall also reimburse each Holder for any and all fees and expenses, including legal fees and expenses, incurred pursuant to the exercise or the attempted exercise of the Holder’s rights under Section 2.2.

(ii)Within [***] after the later of (A) the date on which the Holder receives notice of the Prohibited Transfer and (B) the date on which the Holder otherwise becomes aware of the Prohibited Transfer, each Holder shall, if exercising the option created hereby, deliver to the Common Holder the certificate or certificates representing shares to be sold, each certificate to be properly endorsed for transfer.

(iii)The Common Holder shall, upon receipt of the certificate or certificates for the shares to be sold by a Holder pursuant to this Section 2.5, pay the aggregate purchase price therefor and the amount of fees and expenses reimbursable under Section 2.5(c)(i) in cash or by other means acceptable to the Holder.

If any Common Holder becomes obligated to sell any Equity Securities to the Company or any Holder under this Agreement and fails to deliver such Equity Securities in accordance with the terms of this Agreement, the Company and/or such Holder may, at its option, in addition to all other remedies it may have, send to such Common Holder the purchase price for such Equity Securities as is herein specified and transfer to the name of the Company or such Holder (or request that the Company effect such transfer in the name of a Holder) on the Company’s books the certificate or certificates representing the Equity Securities to be sold.

2.7Status of Shares. Holders that have exercised their rights to purchase the Offered Shares and/or the Remaining Shares pursuant to Section 2.1 shall acquire the Offered Shares and/or the Remaining Shares free and clear of subsequent rights of first refusal and co-sale rights under this Agreement.

5.Effect of Change in Company’s Capital Structure. If, from time to time, the Company pays a stock dividend or effects a stock split or other change in the character or amount of any of the outstanding stock of the Company, then in such event any and all new, substituted or additional securities to which a Common Holder is entitled by reason of such Common Holder’s ownership of Equity Securities shall be immediately subject to the rights and obligations set forth in this Agreement with the same force and effect as the stock subject to such rights immediately before such event.

[***].

11.Severability.

Each Common Holder has entered into a stock purchase agreement or stock restriction agreement with the Company on the Company’s standard form (together with any additional stock purchase agreements, stock restriction agreements or option agreements that a Common Holder may enter into with the Company, the “Purchase Agreements”), which agreement contains a right of first refusal provision in favor of the Company. For so long as this Agreement remains in existence, the right of first refusal provisions contained in this Agreement shall supersede the right of first refusal

provisions contained in the Common Holder’s Purchase Agreements; provided, however, that the other provisions of the Common Holder’s Purchase Agreements shall remain in full force and effect.

Notwithstanding Section 10 of this Agreement, no consent shall be necessary to add such additional Common Holders as signatories to this Agreement and update Schedule A accordingly.
