NOW THEREFORE, for good and valuable consideration; the receipt and adequacy of which is hereby acknowledged by the parties, the parties agree as follows:

1. Certain Defined Terms. As used in this Agreement, the following terms shall have the following respective meanings:

(a) “Affiliate” shall have the meaning assigned to it under Rule 405 of the Securities Act.

(b) “Board” shall mean the Board of Directors of the Company.

(c) “Common Stock” shall mean the common stock, $0.001 par value, of the Company, and any other shares of capital stock issued or issuable with respect thereto (whether by way of a stock dividend or stock split or in exchange for or in replacement of or upon conversion of such shares or otherwise in connection with a combination of shares, recapitalization, merger, consolidation or other corporate reorganization).

(d) “Major Investor” means any Investor that, individually or together with such Investor’s Affiliates, holds at least 373,000 shares of Preferred Stock (subject to adjustment for stock splits, combinations and the like).

(e) “Preferred Stock” shall mean the Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock.

(f) “Securities Act” shall mean the Securities Act of 1933, as amended.

(g) “Series A Preferred Stock” shall mean those shares of Preferred Stock designated as Series A Convertible Preferred Stock of the Company, $0.001 par value, and any other shares of capital stock issued or issuable with respect thereto (whether by way of a stock dividend or stock split or in exchange for or in replacement of or upon conversion of such shares or otherwise in connection with a combination of shares, recapitalization, merger, consolidation or other corporate reorganization).

2. Number of Shares of Stock. Whenever any provision of this Agreement calls for any calculation based on a number of shares of Common Stock held by any Stockholder, the number of shares deemed to be held by such Stockholder shall be the total number of shares of Common Stock then owned by such Stockholder, plus the total number of shares of Common Stock issuable upon conversion of any convertible securities (including Preferred Stock) or exercise of any vested options, warrants or subscription rights then owned by such Stockholder.

3. Restrictions on Transfer of Shares. Except as otherwise provided in this Agreement, no Key Holder will sell, assign, transfer, pledge, hypothecate, or otherwise encumber or dispose of in any way, all or any part of, any interest in the Stock now or hereafter owned or held by such Stockholder (each, a “Transfer”). Any Transfer of Stock by a Key Holder not made in conformance with this Agreement will be null and void, will not be recorded on the books of the Company and will not be recognized by the Company.

4. Rights of First Refusal.

(a) Transfer Notice. If at any time a Key Holder (a “Transferring Holder”) proposes or agrees to Transfer all, any part of, or any interest in Common Stock to one or more third parties pursuant to an understanding with such third parties, then such Transferring Holder must give the Company and each Major Investor written notice of the intention of the Transferring Holder to make the Transfer (the “Transfer Notice”), which Transfer Notice must include: (i) the quantity and a description of the Stock to be transferred (the “Offered Shares”); (ii) the identity of the prospective transferee(s); and (iii) the consideration and the material terms and conditions upon which the proposed Transfer is to be made (which must be stated in cash). The Transfer Notice must certify that the Transferring 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 must also include a copy of any written proposal, term sheet or letter of intent or other agreement relating to the proposed Transfer.

(b) Company’s Option. The Company will have an option for a period of 60 days from receipt 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, thereby, purchase all, or any portion of, the Offered Shares by notifying the Transferring Holder in writing before expiration of such 60-day period as to the number of such shares which the Company wishes to purchase. If the Company gives the Transferring Holder notice that the Company desires to purchase such shares, then the Company must pay for the Offered Shares by check, wire transfer or any combination thereof against delivery of the Offered Shares to be purchased at a place agreed upon between the parties and at the time of the scheduled closing therefor, which must be no later than 120 days after the Company receives the Transfer Notice, unless the Transfer Notice contemplated a later closing with the prospective third party transferee(s). If the Company fails to purchase all of the Offered Shares by exercising the option granted in this Section 4(b) within the period provided, the Remaining Shares (as defined below) will be subject to the options granted to the Major Investors under this Agreement.

(c) Additional Transfer Notice. Subject to the Company’s right set forth in Section 4(b), if at any time any Transferring Holder proposes a Transfer, then, after the Company has declined to purchase all, or a portion of, the Offered Shares, the Transferring Holder must give each Major Investor an additional transfer notice (the “Additional Transfer Notice”), which must include all of the information and certifications required in a Transfer Notice and must additionally identify the Offered Shares that the Company has declined to purchase (the “Remaining Shares”) and briefly describe the Major Investors’ rights of first refusal and co-sale rights with respect to the proposed Transfer.

(d) Non-Transferring Holders’ Option. The Major Investors will have an option for a period of 60 days from the Transferring Holder’s delivery of the Additional Transfer Notice to the Major Investors to elect to purchase their respective pro rata shares 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 Major Investor may exercise such purchase option and thereby purchase all or any portion of its pro rata share (with any reallotments as provided below) of the Remaining Shares, by notifying the Transferring Holder and the Company in writing, before expiration of the 60-day period as to the number of such shares which such Major Investor wishes to purchase (including any reallotment). Each Major Investor’s pro rata share of the Remaining Shares will be equal to a fraction of the Remaining Shares, of which the number of shares of Common Stock (including shares of Common Stock issuable upon conversion of Preferred Stock) owned by such Major Investor on the date of the Transfer Notice will be the numerator and the total number of shares of Common Stock (including shares of Common Stock issuable upon conversion of Preferred Stock) held by all Major Investors on the date of the Transfer Notice will be the denominator. Each Major Investor will have a right of reallotment such that, if any other Major Investor fails to exercise the right to purchase its full pro rata share of the Remaining Shares, the other participating Major Investors may exercise an additional right to purchase, on a pro rata basis, the Remaining Shares not previously purchased. Each Major Investor will be entitled to apportion Remaining Shares to be purchased among its partners, members and Affiliates, provided that such Major Investor notifies the Transferring Holder and the Company of such allocation. If a Major Investor gives the Transferring Holder notice that such Non-Transferring Holder desires to purchase its pro rata share of the Remaining Shares and, as the case may be, its reallotment, then payment for the Remaining Shares must be by check, wire transfer or any combination thereof against delivery of the Remaining Shares to be purchased at a place agreed upon among the parties and at the time of the scheduled closing therefor, which must be no later than 60 days after the Major Investor’s receipt of the Additional Transfer Notice, unless the Additional Transfer Notice contemplated a later closing with the prospective third party transferee(s).

5. Right of Co-Sale.

(a) To the extent that the Company and the Major Investors have not exercised their rights to purchase the Offered Shares or the Remaining Shares, as applicable, within the time periods specified in Section 4, the Transferring Holder will, subject to the rights of co-sale set forth in this Section 5, have a period of 60 days from the expiration of such rights in which to sell the Remaining Shares not purchased by the Major Investors to the third-party purchaser(s) identified in the Transfer Notice upon the terms and conditions (including the purchase price) no more favorable than those specified in the Transfer Notice. If the Transferring Holder does not consummate the Transfer of Remaining Shares not purchased by the Major Investors within such 60-day period, the Company’s first refusal rights and the Major Investors’ first refusal rights and rights of co-sale will again be applicable to any subsequent proposed disposition of the such shares of Common Stock by the Transferring Holder until such rights lapse in accordance with this Agreement.

(b) Each Major Investor that notifies the Transferring Holder in writing within 90 days after receipt of the Additional Transfer Notice referred to in Section 4(c) (a “Co-Selling Holder” for purposes of this Section 5) will have the right to participate in the Transfer of any

Remaining Shares pursuant to Section 5(a) on the same terms and conditions as specified in the Transfer Notice. Such Co-Selling Holder’s notice to the Transferring Holder must indicate the number of shares of Stock the Co-Selling Holder wishes to Transfer under its right to participate. To the extent one or more of the Co-Selling Holders exercise such right of participation in accordance with the terms and conditions set forth below, the number of shares of Stock that the Transferring Holder may Transfer pursuant to Section 5(a) will be correspondingly reduced.

(c) Each Co-Selling Holder may Transfer all or any part of that number of shares of Common Stock equal to the product obtained by multiplying (i) (A) the aggregate number of shares of Common Stock covered by the Transfer Notice minus (B) the aggregate number of shares of Common Stock purchased by the Company and/or the Major Investors pursuant to Section 4, by (ii) a fraction, (X) the numerator of which is the number of shares of Common Stock (including shares of Common Stock issuable upon conversion of Preferred Stock) owned by such Co-Selling Holder on the date of the Additional Transfer Notice and (Y) the denominator of which is the total number of shares of Common Stock (including shares of Common Stock issuable upon conversion of Preferred Stock) owned by the Transferring Holder and all of the Major Investors on the date of the Additional Transfer Notice.

(d) Each Co-Selling Holder must effect its participation in the Transfer by promptly delivering to the Transferring 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 Co-Selling Holder elects to sell; or

(ii) the type and number of shares of Preferred Stock that are at such time convertible into the number of shares of Common Stock which such Co-Selling Holder elects to sell; provided, however, that if the prospective third-party purchaser objects to the delivery of such type of Preferred Stock in lieu of Common Stock, such Co-Selling Holder must convert such Preferred Stock into Common Stock and deliver Common Stock as provided in this Section 5. The Company agrees to make any such conversion concurrent with the actual Transfer of such shares to such third-party purchaser and contingent on such Transfer.

(e) The stock certificates that the Co-Selling Holder delivers to the Transferring Holder pursuant to this Section 5(e) will be delivered to the prospective purchaser in consummation of the Transfer of the Stock pursuant to the terms and conditions specified in the Additional Transfer Notice, and the Transferring Holder will concurrently therewith remit to such Co-Selling Holder that portion of the sale proceeds to which such Co-Selling Holder is entitled by reason of its participation in such sale. To the extent that any prospective third-party purchaser(s) prohibits such assignment or otherwise refuses to purchase Stock from a Co-Selling Holder exercising its rights of co-sale hereunder, the Transferring Holder shall not Transfer to such third-party purchaser(s) any Common Stock owned by the Transferring Holder unless and until, simultaneously with such sale, the Transferring Holder purchases such Stock from such Co-Selling Holder for the same consideration and on the same terms and conditions as the proposed Transfer described in the Transfer Notice.

6. Non-Exercise of Rights. The exercise or non-exercise of the rights of the Company and the Major Investors under Sections 4 or 5 will not adversely affect such rights of the Company and the Major Investors to make subsequent purchases of Stock from the Transferring Holders or to subsequently participate in Stock Transfers by a Transferring Holder in accordance with this Agreement.

7. Permitted Transferees; No Third-Party Beneficiaries.

(a) The provisions of Sections 4 and 5 of this Agreement shall not apply:

(i) to Transfers by a Key Holder of his, her or its Common Stock to such Key Holder’s Affiliate(s), or among such Key Holder’s Family Group (in each case, a “Key Holder Permitted Transferee”), including pursuant to applicable laws of descent and distribution, by will or as a bona fide gift;

(ii) to a repurchase of Stock from a Key Holder by the Company at a price no greater than that originally paid by such Key Holder for such Stock and pursuant to an agreement containing vesting and/or repurchase provisions approved by at least a majority of the Company’s Board of Directors; or

(iii) any transfer pursuant to a merger, consolidation or winding up and dissolution of the Company or a public offering of the Company’s shares;

provided, that the restrictions contained in Sections 4 and 5 shall continue to be applicable to the Stock after any such Transfer; and provided further, that any Key Holder Permitted Transferee shall have agreed in writing to be bound by the provisions of this Agreement affecting the Common Stock so Transferred, including, without limitation, Sections 4 and 5. For purposes of this Agreement, “Family Group” means a Key Holder’s ancestors, brother, sister, spouse and descendants (whether natural or adopted), or any other relative approved by the Board of Directors and any trust solely for the benefit of such Stockholder, and/or such party’s spouse, and/or such party’s descendants.

(b) Each Key Holder agrees, as a condition to any Transfer of his, her or its shares of Stock, to cause the transferee to agree to all of the provisions of this Agreement, whereupon such Transfer the transferee shall be subject to the provisions hereof. This Agreement and the rights and obligations of the parties hereunder shall inure to the benefit of, and be binding upon, their respective successors, assigns and legal representatives, but shall not otherwise be for the benefit of any third party.

8. Other Transfers. Prior to any proposed Transfer of any Stock (other than under the circumstances described in Sections 4 or 5), the Stockholder proposing such Transfer shall give written notice to the Company of its intention to effect such transfer. Each such notice shall describe the manner of the proposed Transfer and must be accompanied by a written agreement signed by the proposed transferee and dated as of the date of such proposed Transfer, and, if requested by the Company, shall be accompanied by an opinion of counsel in form and substance satisfactory to the Company to the effect that the proposed Transfer may be effected without registration under the Securities Act and any applicable state securities laws, whereupon the Stockholder shall be entitled to Transfer such Stock in accordance with the terms of its notice;

provided, however, that no such opinion of counsel shall be required for a Transfer (i) by a Key Holder to a Key Holder Permitted Transferee, (ii) by an Investor to one or more partners or members of the transferor (in the case of a transferor that is a partnership or a limited liability company, respectively), to an Affiliate or to one or more shareholders (in the case of a transferor that is a corporation), or (iii) with respect to any Investor, to any Affiliate of such Investor or any entity or investment vehicle, including a partnership, in which such Investor and/or its Affiliates has a majority economic interest or which is managed by such Investor or any of its Affiliates (each of (ii) and (iii) a “Permitted Transferee”). In addition, unless consented to by the holders of sixty percent (60%) of the Preferred Stock then outstanding (voting as a separate class on an as-converted to Common Stock basis), no Stockholder shall transfer Common Stock and/or Preferred Stock representing twenty percent (20%) or more of the aggregate voting power of the Company during any consecutive twelve (12)-month period (whether in a single transaction or a series of related transactions and including any transfers by such Stockholder’s affiliates) to any party other than the Company; provided that this Section 8 shall not apply to transfers by any Stockholder to any affiliated partnership or entity or Family Group of such Stockholder or transfers permitted by any stock plan or agreement adopted by the Board.

9. Prohibited Transfers. If any Stockholder Transfers any Stock in contravention of the terms of this Agreement, including, without limitation, the right of first refusal and co-sale rights under Sections 4 or 5 (a “Prohibited Transfer”), the parties agree that such Prohibited Transfer will be null and void, and the Company agrees it will not effect such a Prohibited Transfer nor will it treat any alleged transferee(s) as the holder of such Stock.

10. Right of First Offer.

(a) Subject to the terms and conditions specified in this Section 10, each Major Investor shall have a right of first offer with respect to future proposed offers, sales or issuances by the Company of Equity Securities. A Major Investor shall be entitled to apportion the right of first offer hereby granted among its Affiliates in such proportions as it deems appropriate. For purposes of this Agreement, “Equity Securities” shall mean, (i) any Common Stock, Preferred Stock or other capital stock of the Company; (ii) any security convertible into or exercisable or exchangeable for, with or without consideration, any Common Stock, Preferred Stock or other capital stock of the Company (including any option to purchase such a convertible security), (iii) any security carrying any warrant or right to subscribe to or purchase any Common Stock, Preferred Stock or other capital stock of the Company or (iv) any such warrant or right.

(b) Each time the Company proposes to offer, sell or issue any Equity Securities, the Company shall first make an offering of such Stock to each Major Investor in accordance with the following provisions:

(i) The Company shall deliver a notice to each Major Investor stating (1) the Company’s bona fide intention to offer such Equity Securities, (2) the amount and form of Equity Securities to be offered, and (3) the price and terms, if any, upon which it proposes to offer such Equity Securities (the “ROFO Notice”).

(ii) By written notification received by the Company, within 20 days after receipt of the ROFO Notice, each Major Investor may elect to purchase or obtain, at the price and on the terms specified in the ROFO Notice, up to that portion of such Equity Securities which equals the proportion that the number of shares of Common Stock (assuming full conversion and exercise of all convertible or exercisable securities of the Company) issued and held by such Major Investor bears to the total number of shares of Common Stock of the Company then outstanding (assuming full conversion and exercise of all convertible or exercisable securities). The Company shall promptly, in writing, inform each Major Investor which elects to purchase all the Equity Securities available to it (the “Fully-Exercising Investor”) of any other Major Investor’s failure to do likewise. During the 10-day period commencing after such information is given, each Fully-Exercising Investor shall be entitled to obtain that portion of the Equity Securities for which Major Investors were entitled to subscribe, but which were not subscribed for by the Major Investors, which is equal to the proportion that the number of shares of Common Stock then held (assuming full conversion and exercise of all convertible or exercisable securities) by such Fully-Exercising Investor bears to the total number of shares of Common Stock then held (assuming full conversion and exercise of all convertible or exercisable securities) by all Fully-Exercising Investors who wish to purchase any of the unsubscribed shares.

(c) If all shares of Stock referred to in the ROFO Notice, which Major Investors are entitled to obtain pursuant to Section 10(b)(ii), are not elected to be obtained as provided in Section 10(b)(ii) hereof, the Company may, during the 90-day period following the expiration of the 10-day period provided in Section 10(b)(ii), offer the remaining unsubscribed portion of such Equity Securities to any person or persons at a price not less than, and upon terms no more favorable to the offeree than, the price and terms specified in the ROFO Notice. If the Company does not enter into an agreement for the sale of the Equity Securities within such 90-day period, or if such agreement is entered into within such 90-day period but not consummated within 30 days after the execution thereof, the right provided hereunder shall be deemed to be revived and such Equity Securities shall not be offered unless first reoffered to the Major Investors in accordance herewith.

(d) The right of first offer in this Section 10 shall not be applicable to Excluded Stock as that term is defined Article 4(A), Section 6(b) of the Company’s Certificate of Incorporation.

(e) The right of first offer set forth in this Section 10 may not be assigned or transferred, except that such right is assignable by each Major Investor to any Major Investor Permitted Transferee or any transferee acquiring not less than 500,000 shares of Preferred Stock or Common Stock issuable upon conversion of Preferred Stock (or a combination thereof) (subject to adjustment for stock splits, combinations and the like). Any transferee to whom rights under Section 10 of this Agreement are transferred shall as a condition to such transfer, deliver to the Company a written instrument by which such transferee agrees to be bound by the obligations imposed upon a Major Investor under this Agreement to the same extent as if such transferee were a Major Investor under this Agreement.

(f) The rights of first refusal established by this Section 10 shall not apply to, and shall terminate on the earliest to occur of (a) a QPO or (b) a Liquidation Event or a Deemed

Liquidation Event, other than an Asset Sale (each, as defined in the Company’s Certificate of Incorporation). Notwithstanding Section 21 hereof, the rights of first refusal established by this Section 10 may be amended, or any provision waived with and only with the written consent of the Company and the Major Investors holding not less than sixty percent (60%) of the Common Stock then held (assuming full conversion and exercise of all convertible or exercisable securities) held by all Major Investors, or as permitted by Section 21, provided, however, that if any Major Investor waives the rights of first refusal established by this Section 10 pursuant to this Section 10(f) and purchases the Equity Securities that are the subject of such waiver (a “Waiving Participant”), each Major Investor shall have the right to purchase that portion of its pro rata share of such Equity Securities equal to the greatest portion of any Waiving Participant’s pro rata share as calculated in Section 10(b)(ii) actually purchased by any Waiving Participant.

11. Drag-Along Rights.

(a) Applicability to Drag-Along Sale. In the event that the Board, the holders of at least sixty percent (60%) of the Preferred Stock then outstanding (voting as a separate class on an as-converted to Common Stock basis) (the “Proposing Holders”) and, in the case of a Deemed Liquidation Event (as defined in the Company’s then-existing Certificate of Incorporation) only, the Series A Director and the Series B Director (each as defined below), approve a Deemed Liquidation Event (as defined in the Company’s then-existing Certificate of Incorporation) (such event referred to herein as the “Drag-Along Sale”) or a Financing Transaction (as defined below), then (i) (A) if the Drag-Along Sale is structured as a merger or consolidation of the Company, or a sale of all or substantially all of the Company’s assets, each Stockholder agrees to be present, in person or by proxy, at all meetings for the vote thereon, to vote all shares of capital stock held by such person for and raise no objections to such Drag-Along Sale, and waive and refrain from exercising any dissenters rights, appraisal rights or similar rights in connection with such merger, consolidation or asset sale, or (B) if the Drag-Along Sale is structured as a sale of the stock of the Company, each Stockholder shall each agree to sell their Stock on the terms and conditions approved by the Proposing Holders; provided in each case that such terms do not provide that such Stockholder would receive as a result of such Drag-Along Sale less than the amount that would be distributed to such Stockholder in the event the proceeds of such Drag-Along Sale of the Company were distributed in accordance with the liquidation preferences set forth in Company’s then-existing Certificate of Incorporation; and (ii) the Stockholders shall each take all necessary and desirable actions approved by the Proposing Holders in connection with the consummation of the Drag-Along Sale or Financing Transaction, as applicable, including (A) executing such agreements and such instruments and other actions reasonably necessary to provide the representations, warranties, indemnities, covenants, conditions, non-compete agreements, escrow agreements and other provisions and agreements relating to such Drag-Along Sale or Financing Transaction, as applicable, and effectuate the allocation and distribution of the aggregate consideration upon the Drag-Along Sale; (B) not depositing, and causing their Affiliates not to deposit, except as provided in this Agreement, any shares of Stock owned by such party or Affiliate in a voting trust or subject any shares of Stock to any arrangement or agreement with respect to the voting of such shares of Stock, unless specifically requested to do so by the acquiror in connection with the Drag-Along Sale or Financing Transaction, as applicable; and (C) refraining from exercising any dissenter’s rights or rights of appraisal under applicable law at any time with respect to such Drag-Along Sale. A

“Financing Transaction” means any transaction or series of related transactions resulting in the issuance of debt or equity securities of the Company principally for bona fide equity financing purposes in which cash is received by the Company or any successor or indebtedness of the Company is cancelled or converted or a combination thereof occurs.

(b) Proxy Rights. In connection with the pursuit and consummation of any Drag-Along Sale or Financing Transaction, each Stockholder hereby: (i) grants the Secretary of the Company, or other duly authorized officer, an irrevocable proxy (which shall be and shall be deemed to be coupled with an interest) to vote (by actual vote or by written consent) the shares held by such Stockholder or its successors and permitted assigns and transferees in favor of any Drag-Along Sale or Financing Transaction pursued in connection with this Section 11 in the event that such Stockholder or its successors and permitted assigns and transferees fail to consent in writing or vote for any such Drag-Along Sale or Financing Transaction; and (ii) agrees to promptly execute and deliver (without unreasonable condition or delay) any transaction agreement(s) and documentation (including, without limitation, stockholder agreements, waivers and releases, and affiliate letters) deemed necessary, appropriate or advisable by the Proposing Holders in connection with the Drag-Along Sale or Financing Transaction. The proxy, so long as any party hereto is an individual, will survive the death, incompetency and disability of such party or any other individual holder of capital stock of the Company, and, so long as any party hereto is an entity, will survive the merger or reorganization of such party or any other entity holding any capital stock of the Company. In addition to any other rights and remedies available to it at law or in equity, the Proposing Holders or the Company will be entitled to specifically enforce the terms of this Agreement with respect to or related to any Drag-Along Sale or Financing Transaction. Notwithstanding any other provision in this Agreement, each Stockholder shall maintain its right, if applicable, to exercise any rights pursuant to Section Article 4(A), Section 7(b), Article 4(A), Section 8, Article 4(A), Section 9 and Article 4(A), Section 10.

25. Captions. Captions are for convenience only and are not deemed to be part of this Agreement.

Any signature page delivered electronically or by facsimile (including without limitation transmission by .pdf or other fixed image form) shall be binding to the same extent as an original signature page.

28. Entire Agreement. This Agreement (including all schedules and exhibits attached hereto, if any) constitutes the full and entire understanding and agreement among the parties with respect to the subject matter hereof and hereby supersedes all other agreements of the parties to the extent such agreements relate to the subject matter hereof.
