(a) The Company hereby grants registration rights to the Series Preferred Shareholders upon the terms and conditions set forth in this Agreement.

7

(b) For the purposes of this Agreement, Registrable Securities will cease to be Registrable Securities when (i) a registration statement covering such Registrable Securities has been declared effective under the Act by the SEC and such Registrable Securities have been disposed of pursuant to such effective registration statement, (ii) the entire amount of Registrable Securities proposed to be sold by a Holder in a single sale, in the opinion of counsel satisfactory to the Company and the Holder, each in their reasonable judgment, may be distributed to the public without any limitation as to volume pursuant to Rule 144 (or any successor provision then in effect) under the Act, (iii) the Registrable Securities are proposed to be sold or distributed by a Person not entitled to the registration rights granted by this Agreement or (iv) three (3) years have elapsed since the IPO Effectiveness Date.

(c) A Person is deemed to be a Holder whenever such Person owns of record Registrable Securities, or holds an option to purchase, or a security convertible into or exercisable or exchangeable for, Registrable Securities whether or not such acquisition or conversion has actually been effected and disregarding any legal restrictions upon the exercise of such rights. If the Company receives conflicting instructions, notices or elections from two (2) or more Persons with respect to the same Registrable Securities, the Company may act upon the basis of the instructions, notice or election received from the registered owner of such Registrable Securities.

Section 2.2 Demand Registration.

(a) If the Company shall receive at any time after the earlier of (i) three (3) years after the date hereof or (ii) the IPO Effectiveness Date a written request from greater than seventy-five percent (75%) in interest of the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders, voting together as a single class, that the Company register, under the Act (other than pursuant to a registration statement on Form S-4 or S-8 or any successor thereto) and under the securities or “blue sky” laws of any jurisdiction designated by such Holder or Holders (a “Demand Registration”), the number of Registrable Securities held by such Holders and any Affiliate thereof stated in such request, then the Company shall (i) within ten (10) days of receipt thereof, give written notice of such request to all Series E Shareholders and Series D Shareholders who own more than twenty percent (20%) of the outstanding shares of such respective Series as well as to (x) the Series F Shareholders, other than any Series F Shareholder who has sent a prior written notice to the Company that such Series F Shareholder does not want to receive any such notice of a Demand Registration, and (y) the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders not participating in the request for a Demand Registration (collectively, the “Non-Demanding Shareholders”) and (ii) take such steps as are

8

necessary to prepare for the registration of the Registrable Securities and file as soon as practicable, and in any event within forty-five (45) days of the receipt of such request, a registration statement under the Act covering all Registrable Securities that the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders request to be registered, including any shares held by Affiliates of such Holders and any shares requested to be included in such registration by the Non-Demanding Shareholders within ten (10) days of receipt of written notice of such registration by such Holders, subject to the limitations contained herein. Notwithstanding the foregoing, the Company shall not be obligated to effect more than two (2) Demand Registrations pursuant to this Section 2.2. If at the time of any request to register Registrable Securities pursuant to this Section 2.2, the Company (i) is engaged in, or has fixed plans to engage in within one hundred eighty (180) days of the time of such request, a Qualified IPO, (ii) delivers notice to the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders requesting such registration within thirty (30) days of such registration request of its intent to file a registration statement for a Qualified IPO within ninety (90) days, or (iii) is engaged in any other activity that, in the good faith determination of the Board, would be adversely affected by the requested registration and cause material detriment to the Company, then the Company may, at its option, direct that such request be delayed for a reasonable period not in excess of one hundred twenty (120) days from the date of such request, such right to delay a request to be exercised by the Company not more than once in any twelve (12) month period. In addition, the Company shall not be required to effect any registration within ninety (90) days after the effective date of any other registration statement of the Company (other than a registration statement on Form S-4 or S-8 or any successor thereto). Each request for a Demand Registration shall state the amount of the Registrable Securities proposed to be sold and the intended method of disposition thereof.

(b) If the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders initiating the registration request 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 Section 2.2(a). The underwriter or underwriters shall be selected by the Company and shall be reasonably acceptable to greater than seventy-five percent (75%) in interest of the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders, voting together as a single class. The Non-Demanding Shareholders and the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders proposing to distribute their securities through such underwriting shall (together with the Company as provided in Section 2.6(e)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting.

9

Notwithstanding any other provision of this Section 2.2, if the underwriter advises the Non-Demanding Shareholders and the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders in writing that market factors require a limitation of the number of shares to be underwritten, then the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders initiating such registration shall so advise all holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among the Non-Demanding Shareholders and the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders initiating such registration in proportion to the amount of Shares owned by each such Holder and their respective Affiliates; provided, however, that the number of shares of Registrable Securities to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting. If any Non-Demanding Shareholder that has requested inclusion in such registration in accordance with the terms hereof does not agree to the terms of any such underwriting agreed to by the Company, the underwriter and the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders initiating the registration, such Non-Demanding Holder shall be excluded therefrom by written notice from the Company, the underwriter or the Holders initiating the registration. The Registrable Securities so excluded also shall be withdrawn from 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 2.2(b), then the Company shall offer to all Holders who have retained the right to include Registrable Securities in the registration the right to include additional securities in the registration in an amount equal to the number of shares so withdrawn, with such shares to be allocated in proportion to the amount of Registrable Securities owned by each Holder.

(c) The Company shall use its best efforts to cause any such Demand Registration to become and remain effective as soon as practicable, but in any event not later than ninety (90) days after it receives a request under Section 2.2(a) hereof. A registration shall not constitute a Demand Registration until it has become effective and remains continuously effective for the lesser of (i) the period during which all Registrable Securities registered in the Demand Registration are sold and (ii) one hundred eighty (180) days; provided, however, that a registration shall not constitute a Demand Registration if (x) after such Demand Registration has become effective, such registration or the related offer, sale or distribution of Registrable Securities thereunder is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court for any reason not attributable to the Series

10

C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders and such interference is not thereafter eliminated in a reasonable period of time, (y) the conditions to closing specified in the underwriting agreement, if any, entered into in connection with such Demand Registration are not satisfied or waived, other than by reason of a failure by the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders or the Series C Shareholders or (z) if the request for such Demand Registration is withdrawn by the requesting Holders and such Holders reimburse the Company for any expenses incurred in relation thereto.

Section 2.3 Company Registration.

If (but without any obligation to do so) the Company proposes to register any of its Common under the Act in connection with an underwritten offering of such Common for its own account (other than a registration statement on Form S-4 or S-8 or any successor thereto), then the Company shall give written notice of such proposed filing to the Holders at least thirty (30) days before the anticipated filing date, and such notice shall describe the proposed registration and distribution and offer such Holders the opportunity to register the number of Registrable Securities as the Holders may request. Upon the written request of any Holder given within twenty (20) days after mailing of such notice by the Company in accordance with Section 8.5, the Company shall, subject to the provisions of Section 2.6, cause to be registered under the Act all of the Registrable Securities that the Holders requested to be registered.

Section 2.4 Form S-3 Registration.

(a) In case the Company shall receive from any Holder or Holders a written request or requests that the Company effect a registration on Form S-3 and any related “blue sky” law qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holders (which amount of Registrable Securities shall have a fair market value of at least $500,000 in the aggregate, based upon the last sales price of the Common on a national exchange or over-the-counter market, as applicable, on the day immediately preceding the date of such request), the Company will (i) promptly give notice of the proposed registration, and any related “blue sky” law qualification or compliance, to all other Holders and (ii) as soon as practicable, but in any event not more than thirty (30) days after its receipt of such request, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, “blue

11

sky” law qualification or compliance, pursuant to this Section 2.4: (w) if Form S-3 is not available for such offering by the Holders; (x) 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) at an aggregate price to the public (after deduction of any underwriters’ discounts or commissions) of less than $500,000; (y) if the Company has, within the twelve (12) month period preceding the date of such request, already effected one (1) such registration on Form S-3 for the Holders pursuant to this Section 2.4; or (z) if the Company shall furnish to the initiating Holders a certificate signed by the Chief Executive Officer or President of the Company stating that in the good faith judgment of the Board, it would be materially detrimental to the Company and its shareholders for such Form S-3 Registration to be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than sixty (60) days after receipt of the request of the Holders under this Section 2.4.

(b) Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the Holders.

(c) No registration requested by any Holder pursuant to this Section 2.4 shall be deemed a Demand Registration pursuant to Section 2.2.

(a) Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its reasonable best efforts to cause such registration statement to become effective, and, upon the request of the

12

Holders of a majority of the votes then represented by the Registrable Securities held by the Holders registered thereunder, keep such registration statement effective for a period of up to one hundred eighty (180) days or until the distribution contemplated in the registration statement has been completed (the “Effectiveness Period”); provided, however, that (i) the Effectiveness Period shall be extended for a period of time equal to the period the Holders refrain from selling any securities included in such registration at the request of an underwriter of Common (or other securities) of the Company; and (ii) in the case of any registration of Registrable Securities on Form S-3 that are intended to be offered on a continuous or delayed basis, the Effectiveness Period shall be extended, if necessary, to keep the registration statement effective until all such Registrable Securities are sold, provided that Rule 415, or any successor rule under the Act, permits an offering on a continuous or delayed basis, and provided further that applicable rules under the Act governing the obligation to file a post-effective amendment permit, in lieu of filing a post-effective amendment that (x) includes any prospectus required by Section 10(a)(3) of the Act or (y) reflects facts or events representing a material or fundamental change in the information set forth in the registration statement, the incorporation by reference of information required to be included in (x) and (y) above to be contained in periodic reports filed pursuant to Section 13 or 15(d) of the 1934 Act in the registration statement. In the event that, in the good faith and reasonable judgment of the Company, it is advisable to suspend use of the prospectus relating to such registration statement for a discrete period of time (a “Deferral Period”) due to pending material corporate developments or similar material events that have not yet been publicly disclosed and as to which the Company believes public disclosure will be prejudicial to the Company, the Company shall deliver a certified resolution of the Board, signed by a duly authorized officer of the Company, to each Holder of Registrable Securities covered by such registration statement, to the effect of the foregoing and, upon receipt of such certificate, such Holders agree not to dispose of such Holders’ Registrable Securities covered by such registration or prospectus (other than in transactions exempt from the registration requirements under the Act); provided, however, that such Deferral Period shall be no longer than forty-five (45) days and that there may be only one Deferral Period during any twelve (12) month period.

(e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering; provided that each Holder participating in such underwriting shall also enter into and perform its obligations under such underwriting agreement.

(f) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the 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, in the light of the circumstances under which they were made, not misleading, and at the request of any such Holder prepare and furnish to such Holder a reasonable number of copies of a supplement or an amendment to such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, 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 in the light of the circumstances then existing.

(j) Make available for inspection by any seller of Registrable Securities, any managing underwriter participating in any disposition pursuant to such registration statement, Holders’ counsel and any attorney, accountant or other agent retained by any such seller or any managing underwriter (each, an “Inspector” and collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”) as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees, and the independent public accountants of the Company, to supply all information reasonably requested by any such Inspector in connection with such registration statement. Records that the Company determines, in good faith, to be confidential and of which it notifies the Inspectors are confidential shall not be disclosed by the Inspectors unless (x) the disclosure of such Records is necessary to avoid or correct a material misstatement or omission in the registration statement, (y) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction or (z) the information in such Records was known to the Inspectors on a non-confidential basis prior to its disclosure by the Company or has been made generally available to the public.

(l) Use its reasonable best efforts to furnish, at the request of any seller of Registrable Securities on the date such securities are delivered to the underwriters for sale pursuant to such registration or, if such securities are not being sold through underwriters, on the date the registration statement with respect to such securities becomes effective, an opinion, dated such date, of counsel representing the Company for the purposes of such registration, addressed to the underwriters, if any, and to the seller making such request, covering such legal matters with respect to the registration in respect of which such opinion is being given as such underwriters, if any, and such seller may reasonably request and are customarily included in such opinions and are reasonably acceptable to counsel representing the Company.

(m) Otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable but no later than fifteen (15) months after the effective date of the registration statement, an earnings statement covering a period of twelve (12) months beginning after the effective date of the registration statement, in a manner which satisfies the provisions of Section 11(a) of the Act and Rule 158 thereunder.

(n) Cooperate with each seller of Registrable Securities and each underwriter participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with the Financial Industry Regulatory Authority, Inc.

16

Section 2.8 Expenses of Registration.

(a) Except as set forth in Section 2.8(b), the Company shall bear and pay all expenses incurred in connection with any registration, filing or qualification of Registrable Securities with respect to two (2) registrations pursuant to Section 2.2, any registrations pursuant to Section 2.3 and any registrations pursuant to Section 2.4 hereof, including (without limitation) all registration, filing and qualification fees, printers’ and accounting fees, “blue sky” fees and expenses, including fees and disbursements of counsel (up to $20,000) related to all “blue sky” matters, fees and expenses of listing any Registrable Securities on any securities exchange or automated quotation system on which shares of Common are then listed, fees and disbursements of counsel for the Company, but excluding stock transfer taxes that may be payable by the selling Holders, the fees and expenses of any counsel pursuant to Section 2.6(i), the fees and expenses of any Inspectors pursuant to Section 2.6(j) and underwriting discounts and commissions relating to Registrable Securities covered by such registration, which shall be borne pro rata by the Holders. Expenses for any and all registrations not specifically payable by the Company pursuant to this Section 2.8(a) shall be borne pro rata by the selling shareholders based on the number of shares of Registrable Securities sold by each such selling shareholder in the offering.

(b) Notwithstanding Section 2.8(a), the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 2.2 if the registration request is subsequently withdrawn at the request of the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders holding a majority of the votes represented by Shares to be registered (in which case all participating holders shall bear such expenses), unless the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders holding a majority of the votes represented by the Shares to be registered agree to forfeit their right to one of the demand registrations to which they are entitled pursuant to Section 2.2; provided, however, that if such withdrawal occurs prior to the date the registration statement shall have become effective and at the time of such withdrawal, the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders have learned of a material adverse change in the financial condition, business, prospects, properties or results of operations of the Company from that known to such Holders at the time of their request and have withdrawn the request with reasonable promptness following disclosure by the Company of such material adverse change, then the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders shall retain their respective rights pursuant to Section 2.2 and the selling Holders shall not be required to pay any of such expenses.

17

Section 2.9 Underwriting Requirements.

In connection with any offering involving an underwriting of shares of Common being issued by the Company, the Company shall be required under Section 2.3 to include any Registrable Securities held by the Holders in such underwriting on the same terms and conditions as the securities of the Company included therein, but only in such quantity as the underwriters determine in their good faith judgment and written opinion will not jeopardize the success of the offering by the Company. If such written opinion states that the registration of all or part of the Registrable Securities that the Holders have requested to be included would materially adversely affect such offering, then the Company shall be required to include in such registration, to the extent of the amount that the underwriters believe may be sold without jeopardizing the success of the offering, first, all of the securities to be offered for the account of the Company; second, the Registrable Securities to be offered for the account of the Series F Shareholders, Series E Shareholders, the Series D Shareholders and Series C-3 Shareholders, pro rata, on an as-if-converted basis, based upon the amount recommended by the underwriters; third, the Registrable Securities to be offered for the account of the Series C-2 Shareholders, pro rata based upon the amount recommended by the underwriters; fourth, the Registrable Securities to be offered for the account of the Series C-1 Shareholders, pro rata based upon the amount recommended by the underwriters; fifth, the Registrable Securities to be offered for the account of the Series C Shareholders, pro rata based upon the amount recommended by the underwriters; sixth, the Registrable Securities to be offered for the account of the Series B-1 Shareholders, pro rata based upon the amount recommended by the underwriters; seventh, the Registrable Securities to be offered for the account of the Series B Shareholders, pro rata based upon the amount recommended by the underwriters; eighth, the Registrable Securities to be offered for the account of the Series A Shareholders, pro rata based upon the amount recommended by the Underwriters; and ninth, any other shares of Common required to be included in such underwriting and so requested to be included, pro rata based upon the amount recommended by the underwriters; provided, however, that the aggregate value of the Registrable Securities to be included in such registration by the Holders may not be so reduced to less than twenty-five percent (25%) of the total value of all securities included in such registration, unless such offering is a Qualified IPO of the Company’s securities, in which case the selling Holders may be excluded if the underwriters make the determination described above and no other shareholders’ securities are included. For purposes of the preceding sentence concerning apportionment, for any selling shareholder that is a Holder of Registrable Securities that is a partnership, limited liability company or corporation, the partners, retired partners, members and shareholders of such Holder, or the estates and family members of any such partners and retired partners or members and any trusts for the benefit of any of the foregoing persons and Affiliates of such Holder shall be deemed to be a single “selling shareholder,” and any pro rata reduction with respect to such “selling shareholder” shall be based upon the aggregate amount of Registrable Securities owned by all entities and individuals included in such “selling shareholder,” as defined in this sentence.

18

Section 2.10 Indemnification.

In the event any Registrable Securities are included in a registration statement under this Article II:

(a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder and their respective officers, directors, trustees, partners, employees, advisors and agents, any underwriter (as defined in the Act) for such Holder and each Person or entity, if any, who controls such Holder or underwriter within the meaning of the Act or the 1934 Act, against any losses, claims, damages, expenses or liabilities (joint or several) to which they may become subject under the Act or the 1934 Act, insofar as such losses, claims, damages, expenses or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively, a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the 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 Act, the 1934 Act, or any rule or regulation promulgated under the Act or the 1934 Act; and the Company will reimburse, as incurred, the Holders and any officer, director, partner, underwriter or controlling person of the Holders, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 2.10(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, delayed or conditioned), nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder or any officer, director, partner, employee, advisor, agent, underwriter or controlling person of such Holder.

(b) To the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each Person, if any, who controls the Company within the meaning of the Act and any underwriter against any losses, claims, damages, expenses or liabilities (joint or several) to which any of the foregoing Persons may become subject, under the Act or the 1934 Act insofar as such losses, claims, damages, expenses or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such

19

registration; and each such Holder will reimburse, as incurred, any legal or other expenses reasonably incurred by any Person intended to be indemnified pursuant to this Section 2.10(b), in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 2.10(b) 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 Holder (which consent shall not be unreasonably withheld, delayed or conditioned); provided further, that, in no event shall the aggregate indemnity payments under this Section 2.10(b) exceed the aggregate proceeds (net of underwriting discounts and commissions) from the sale of the Registrable Securities received by such Holder from the shares sold by such Holder in the offering in question.

(c) Promptly after receipt by an indemnified party under this Section 2.10 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.10, deliver to the indemnifying party a written notice of the commencement thereof; provided, however, that the failure to so notify the indemnifying party shall not relieve the indemnifying party of any liability that it may have to the indemnified party hereunder. The indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. An indemnifying party shall not, without the prior written consent of the indemnified parties, settle, compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder by such indemnified parties (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes a release of such indemnified party reasonably acceptable to such indemnified party from all liability arising out of such claim, action, suit or proceeding or unless the indemnifying party shall confirm in a written agreement reasonably acceptable to such indemnified party, that notwithstanding any federal, state or common law, such settlement, compromise or consent shall not adversely affect the right of any indemnified party to indemnification as provided in this Section 2.10.

20

(d) If the indemnification provided for in this Section 2.10 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 therein, 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. Notwithstanding the foregoing, the liability of each Holder under this Section 2.10(d) shall be limited to an amount equal to the aggregate proceeds (net of underwriting discounts and commissions) from the sale of the Registrable Securities received by such Holder from the shares sold by such Holder in the offering in question.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into by the Company and one or more Holders in connection with a Qualified IPO are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control with respect to the Company and such Holders.

(f) The obligations of the Company and the Holders under this Section 2.10 shall survive the completion of any offering of Registrable Securities in a registration statement under this Article II, and otherwise.

Section 2.11 Assignment of Registration Rights.

The rights to cause the Company to register Registrable Securities pursuant to this Article II may be assigned (but only with all related obligations) by (a) a Holder to a transferee or assignee of such securities who, after such assignment or transfer, holds (together with its Affiliates) at least ten percent (10%) the shares of Registrable Securities originally purchased from the Company by the transferring Holder (subject to appropriate adjustment for stock splits, stock dividends, combinations and other recapitalizations and including for purposes of such calculation the shares of Common then issuable upon conversion of any securities of the Company), (b) a Holder to its partners, members, former partners or former members (or their estates) or Affiliates or (c) a Holder to any family member or trust for the benefit of the Holder; provided: (i) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and

21

address of such transferee or assignee and the Registrable Securities with respect to which such registration rights are being assigned; (ii) such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Agreement; and (iii) such assignment shall be effective only if immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Act.

Section 2.12 Limitations on Subsequent Registration Rights.

From and after the date of this Agreement, the Company shall not, without the prior written consent of greater than seventy-five percent (75%) in interest of the Series C-3 Shareholders, the Series C-2 Shareholders, the Series C-1 Shareholders and the Series C Shareholders, voting together as a single class, enter into any agreement with any holder or prospective holder of any securities of the Company (other than Series E Shareholders who become party to this Agreement) that would allow such holder or prospective holder (a) to include such securities in any registration filed under Section 2.2, Section 2.3 or Section 2.4 hereof, unless under the terms of such agreement, such holder or prospective Holder may include such securities in any such registration only to the extent that the inclusion of such Holder’s securities will not reduce the amount of the Registrable Securities of the Series C-3 Shareholder, the Series C-2 Shareholders, the Series C-1 Shareholders or the Series C Shareholders that are included or (b) to effect a registration that could result in such registration statement being declared effective prior to the earlier of either of the dates set forth in Section 2.2(a) or within 180 days of the effective date of any registration effected pursuant to Section 2.2, Section 2.3 or Section 2.4.

Section 2.13 Termination of Registration Rights.

No Holder shall be entitled to exercise any right provided for in this Article II after the earlier of (i) five (5) years following the IPO Effectiveness Date (the “Registration Date”) and (ii) the date after the IPO Effectiveness Date on which a Holder can sell all shares of Registrable Securities issued to it pursuant to Rule 144(b) under the Act, provided, however, that notwithstanding clause (ii) above, a Holder shall be entitled to exercise its rights under this Article II so long as (x) five (5) years have not elapsed since the Registration Date and (y) such Holder (together with its Affiliates) owns more than one percent (1%) of the outstanding capital stock of the Company.

Section 2.14 “Market Stand-Off” Agreement.

Each Holder hereby agrees that, during the period of duration specified by the Company and an underwriter of Common or other securities of the Company, following the IPO Effectiveness Date, it shall not, to the extent requested in writing by the Company and such underwriter, directly or indirectly sell, offer to sell, contract to sell or dispose of (other than to donees who agree to be similarly bound) any securities of the Company held by it at any time during such period except Common included in such registration; provided, however, that:

(a) such agreement shall be applicable only to the first registration statement of the Company which covers securities to be sold on its behalf in a Qualified IPO;

22

(b) all officers and directors of the Company and all holders of at least one percent (1%) of the Company’s outstanding Common are also subject to such a market stand-off period; and

(c) such market stand-off time period shall not exceed one hundred eighty (180) days.

In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the securities of the Company held by each Holder (and the shares or securities of every person subject to the foregoing restriction) until the end of such period.

Notwithstanding the foregoing, the obligations described in this Section 2.14 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Rule 145 transaction under the Act.

Section 3.4 Right of First Offer.

Subject to the terms and conditions specified in this Section 3.4, the Company hereby grants to each of the Series Preferred Shareholders a right of first offer with respect to future sales by the Company of its Shares.

Except as provided in Section 3.4(d) hereof, each time the Company proposes to offer any Shares, the Company shall first make an offering of such Shares to the Series Preferred Shareholders in accordance with the following provisions:

(a) The Company shall deliver a notice by certified mail (“Notice”) to the Series Preferred Shareholders stating (i) its bona fide intention to offer such Shares, (ii) the number of such Shares to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such Shares.

(b) By written notification to be received by the Company within twenty (20) calendar days after delivery of the Notice, the Series Preferred Shareholders may elect to purchase or obtain, at the price and on the terms specified in the Notice, up to that portion of such Shares that equals the proportion that the number of Shares of Common then held by such shareholder bears to the total number of Shares of Common then outstanding (assuming full conversion and exercise of all convertible or exercisable securities). The Company shall promptly, in writing, inform each shareholder that purchases all Shares available to it (“Fully-Exercising Investor”) of any other shareholder’s failure to do likewise. During the ten (10) day period commencing after such information is given, each Fully-Exercising Investor shall be entitled to obtain that portion of the Shares not subscribed for by the Series Preferred Shareholders that is equal to the proportion that the number of shares of Common then issued and held by such Fully-Exercising Investor bears to the total number of shares of Common issued and held by all Fully-Exercising Investors who wish to purchase their pro rata portion of the unsubscribed Shares (assuming full conversion and exercise of all convertible or exercisable securities).

(c) If all Shares referred to in the Notice that the Series Preferred Shareholders are entitled to obtain pursuant to Section 3.4(b) are not elected to be obtained as provided in Section 3.4(b) hereof, the Company may, during the thirty (30) day period following the expiration of the period provided in Section 3.4(b) hereof, offer the remaining unsubscribed portion of such Shares to any Person or Persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Notice. If the Company does not enter into an agreement for the sale of the Shares within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right of first offer provided under this Section 3.4 shall be deemed to be revived and such Shares shall not be offered unless first offered to the Series Preferred Shareholders in accordance with this Section 3.4. The right of first offer in this Section 3.4 shall not be applicable (i) to the issuance or sale of

25

Common (or options therefor) to employees, directors, consultants or advisors of the Company, for the primary purpose of soliciting or retaining their employment or services, approved by the Board, (ii) to the consummation of a Qualified IPO, (iii) to the issuance of Shares pursuant to the conversion or exercise of convertible or exercisable securities, (iv) to the issuance of Shares solely in connection with a bona fide business acquisition by the Company, whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise, approved by the Board, (v) to Shares issued solely in connection with the establishment of credit facilities, including equipment financings, approved by the Board, (vi) to Shares issued as dividends or distributions on the Preferred, or (vii) to Shares (or derivatives thereof) issued to strategic partners approved by the Board.

The Company agrees as follows:

(a) The Company will promptly pay and discharge, or cause to be paid and discharged, when due and payable, all lawful taxes, assessments, and governmental charges or levies imposed upon the income, profits, property or business of the Company; provided, however, that any such tax, assessment, charge or levy need not be paid if the validity thereof shall currently be contested in good faith by appropriate proceedings and if the Company shall have set aside on its books adequate reserves with respect thereof, and provided further, that the Company will pay all such taxes, assessments, charges or levies forthwith upon the commencement of proceedings to foreclose any lien that may have attached as security therefor. The Company will promptly pay or cause to be paid when due, or in conformance with customary trade terms, all other indebtedness incident to the operations of the Company where the failure to pay any such indebtedness could reasonably be expected to have a Material Adverse Effect on the Company;

(b) The Company will keep its material properties in good repair, working order and condition, reasonable wear and tear excepted, and from time to time make all needful and proper repairs, renewals, replacements, additions and improvements thereto; and the Company will at all times comply with the provisions of all material leases to which it is a party or under which it occupies property so as to prevent any loss or forfeiture thereof or thereunder;

26

(c) Except as otherwise decided in accordance with policies adopted by the Board, the Company will keep its assets that are of an insurable character insured by nationally-recognized insurers against loss or damage by fire, extended coverage and explosion insurance in amounts customary for companies in similar businesses similarly situated; and the Company will maintain, with nationally-recognized insurers, insurance against other hazards, risks and liabilities to persons and property to the extent and in the manner customary for companies in similar businesses similarly situated;

(d) The Company will keep true records and books of account in which full, true and correct entries will be made of all dealings or transactions in relation to its business and affairs in accordance with U.S. GAAP applied on a consistent basis;

(f) The Company shall maintain in full force and effect its corporate existence, rights and franchises and all licenses and other rights to use patents, processes, licenses, trademarks, trade names or copyrights owned or possessed by it and deemed by the Company to be material and necessary to the conduct of its business;

(g) The Company will retain an independent registered public accounting firm acceptable to the holders of a majority of the shares of Series C-3 Preferred who shall certify the Company’s Financial Statements at the end of each fiscal year. In the event the services of the independent registered public accounting firm so selected, or any firm hereafter employed by the Company are terminated, the Company will promptly thereafter notify each of the Major Holders and will request the independent registered public accounting firm whose services are terminated to deliver to each of the Major Holders a letter from such firm setting forth the reasons for the termination of its services. In the event of such termination, the Company will promptly thereafter engage another independent registered public accounting firm acceptable to the holders of a majority of the shares of Series C-3 Preferred. In its notice to the Major Holders, the Company shall state whether the change of accountants was recommended or approved by the Board or any committee thereof;

(h) The Company will cause each person now or hereafter employed by it not considered an executive of the Company and not bound by an employment agreement to enter into a proprietary information and inventions agreement substantially in a form approved by the Company’s legal counsel;

27

(i) The Company shall file the Securities Filings in the time periods required for such filings; and

(j) The Company shall at all times reserve and keep available out of its authorized shares of Common, solely for the purpose of issue or delivery upon conversion or exercise of the Preferred or other securities as provided in the Articles of Incorporation, the maximum number of shares of Common that may be issuable or deliverable upon such conversion or exercise, as the case may be. Such shares of Common are duly authorized and, when issued or delivered in accordance with the Articles of Incorporation, shall be validly issued, fully paid and non-assessable. The Company shall issue such shares of Common in accordance with the terms of the Articles of Incorporation, and otherwise comply with the terms hereof and thereof.

If any Holder proposes to sell or transfer any Shares they hold (“Holder Stock”), then such selling Holder shall promptly give written notice (the “Sale Notice”) to the Company at least thirty-five (35) days prior to the proposed closing of such sale or transfer. The Company shall provide a copy of such Sale Notice to the Series Preferred Shareholders within five (5) days of its receipt thereof. The Sale Notice shall describe in reasonable detail the proposed sale or transfer including, without limitation, the number of shares of Holder Stock to be sold or transferred, the nature of such sale or transfer, the consideration to be paid, and the name and address of each prospective purchaser or transferee. In the event that the sale or transfer is exempted from this Article IV pursuant to the provisions of Section 4.7(a), the Sale Notice shall so state the basis for such exemption.

Section 4.2 Right to Participate.

The Series Preferred Shareholders shall have the right, exercisable upon written notice to such selling Holder within fifteen (15) days after receipt of the Sale Notice from the Company, to participate in such sale of Holder Stock on the same terms and conditions (the “Tag Along Right”). To the extent any of the Series Preferred Shareholders exercises such right of participation in accordance with the terms and conditions set forth in this Article IV, the number of shares of Holder

28

Stock that the selling Holder may sell or transfer in the transaction shall be correspondingly reduced. Any Series Preferred Shareholders may sell all or any part of that number of shares of Common equal to the product obtained by multiplying (i) the aggregate number of shares of Holder Stock covered by the Sale Notice by (ii) a fraction, the numerator of which is the number of shares of Common (on an as-if-converted basis) owned by the shareholder at the time of the sale or transfer and the denominator of which is the total number of shares of Common (on an as-if-converted basis) owned by the selling Holder and the Series Preferred Shareholders participating in such sale or transfer at the time of the sale or transfer (such product being referred to herein as a shareholder’s “Pro Rata Share”).

Section 4.3 Notice.

If any Series Preferred Shareholders elects to participate by selling all or a portion of its Shares in the selling Holder’s sale pursuant to this Article IV, the selling Holder shall provide written notice to the participating shareholders (the “Participants”) confirming the terms of the transfer of shares held by both the Holder and the Participants, including the number of shares calculated to be each shareholder’s Pro Rata Share to be sold by each of the Holder and the Participants.

Section 4.4 Transfer of Shares.

The Participant shall effect its participation in the sale by promptly delivering to the selling Holder for transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, that represent:

(a) the number of shares of Common that such Participant elects to sell; or

(b) that number of shares of Preferred that is at such time convertible into the number of shares of Common that the Participant elects to sell; provided, however, that if the prospective purchaser objects to the delivery of Preferred, such Participant shall convert such Preferred into Common and deliver Common as provided in Section 4.4(a). The Company agrees to make any such conversion concurrent with the actual transfer of such Shares of the purchaser.

Section 4.5 Effecting the Transfer; Refusal of Shares.

The stock certificate or certificates that the Participant delivers to the selling Holder pursuant to Section 4.4 shall be transferred to the prospective purchaser upon consummation of the sale of the Shares pursuant to the terms and conditions specified in the Sale Notice, and the selling Holder shall concurrently therewith remit to the Participant that portion of the sale proceeds to which the Participant 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 from a Participant exercising its Tag Along Right

29

herein, the selling Holder shall not sell to such prospective purchaser or purchasers any Holder Stock unless and until, simultaneously with such sale, the selling Holder shall purchase such Shares from the Participant.

Section 4.6 Future Participation.

The exercise or non-exercise of the rights of the Series Preferred Shareholders hereunder to participate in one or more sales of Holder Stock made by any selling Holder shall not adversely affect their rights to participate in subsequent sales of Holder Stock subject to this Article IV.

Section 4.7 Exempt Transfers.

(a) Holders’ Rights. Notwithstanding the foregoing, the Tag Along Right shall not apply to (i) any pledge of Holder Stock by a Holder made pursuant to a bona fide loan transaction that creates a mere security interest, (ii) any transfer or bona fide gift to such Holder’s ancestors, descendants (including adopted children) or spouse or to trusts for the benefit of such persons, or (iii) any transfer by a Holder to its partners, members, former partners or former members (or their estates) or Affiliates; provided that (x) such Holder shall inform the Company of such pledge, transfer or gift prior to effecting it, (y) the pledgee, transferee or donee shall furnish the Company with a written agreement to be bound by and comply with all provisions of this Agreement applicable to the Holder, and (z) as a result of such pledge, transfer or gift, the Company would not, in the opinion of counsel to the Company, be rendered subject to the reporting requirements of the 1934 Act. Such pledgee, transferee or donee shall be treated as a “Holder” for purposes of this Agreement, with corresponding rights and obligations.

(b) Holders. Notwithstanding the foregoing, the provisions of Article IV shall not apply to the sale of any Holder Stock to the public pursuant to a registration statement filed with, and declared effective by, the SEC under the Act.

Section 4.8 Prohibited Transfers.

(a) Remedies. In the event a Holder should sell any Holder Stock in contravention of the Tag Along Right under this Agreement (a “Prohibited Transfer”), the Participants, in addition to such other remedies as may be available at law, in equity or hereunder, shall have the put option provided in Section 4.8(b) below, and the Holder shall be bound by the applicable provisions of such option.

(b) Sale by the Participants. In the event of a Prohibited Transfer, the Participants shall have the right to sell to such Holder the number of shares of Common equal to the number of shares of Common the Participants would have been entitled to transfer to the purchaser had the

30

Prohibited Transfer been effected pursuant to and in compliance with the terms of this Article IV. Such sale shall be made on the following terms and conditions:

(i) Price. The price per share at which the shares are to be sold to such Holder shall be equal to the price per share paid by the purchaser to the Holder in the Prohibited Transfer (subject to adjustment for conversion to Common, as applicable). The Holder shall also reimburse the Participants for any and all fees and expenses, including legal fees and expenses, incurred pursuant to the exercise or the attempted exercise of the Participant’s rights under this Article IV.

(ii) Delivery. Within ninety (90) days after the earlier of the dates on which the Participants (i) received notice of the Prohibited Transfer or (ii) otherwise became aware of the Prohibited Transfer, the Participants shall, if exercising the option created by this Section 4.8(b), deliver to such Holder the certificate or certificates representing the shares of Common to be sold, each certificate to be properly endorsed for transfer.

(iii) Payment. The Holder shall, upon receipt of the certificate or certificates for the Shares to be sold by the Participants pursuant to this Section 4.8(b), pay the aggregate purchase price therefor and the amount of reimbursable fees and expenses, as specified in Section 4.8(b)(i), in cash or by other means acceptable to the Participants.

(iv) Void Transfers. Notwithstanding the foregoing, any attempt by a Holder to transfer Holder Stock in violation of Article IV hereof shall be void and the Company agrees it will not effect such a transfer nor will it treat any alleged transferee as the holder of such Shares without the written consent of a majority of the votes represented by outstanding Registrable Securities held by the Series Preferred Shareholders.

Section 4.9 Legend.

(a) Each certificate representing shares of Holder Stock now or hereafter owned by the Holder or issued to any person in connection with a transfer pursuant to Article IV hereof shall be endorsed with the following legend:

“THE SALE, PLEDGE, HYPOTHECATION, TRANSFER AND VOTING OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE RESTRICTED BY THE TERMS AND CONDITIONS OF A CERTAIN INVESTORS’ RIGHTS AGREEMENT BY

31

AND AMONG THE SHAREHOLDERS AND THE CORPORATION. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE CORPORATION. THE CORPORATION WILL NOT REGISTER THE TRANSFER OF SUCH SECURITIES ON THE BOOKS OF THE CORPORATION UNLESS AND UNTIL THE TRANSFER HAS BEEN MADE IN COMPLIANCE WITH THE TERMS OF SUCH AGREEMENT.”

(b) Each Holder agrees that the Company may instruct its transfer agent to impose transfer restrictions on the Shares represented by certificates bearing the legend referred to in Section 4.9(a) to enforce the provisions of this Agreement and the Company agrees to promptly do so. The legend shall be removed upon termination of this Agreement or this Article IV.

Section 4.10 Termination of Rights and Obligations.

The rights and obligations set forth in this Article IV shall terminate automatically in the event of a Qualified IPO.

ARTICLE V

RIGHT OF FIRST OPPORTUNITY

Section 5.1 General.

Subject to the terms and conditions of this Article V, each Holder proposing to offer any Shares for sale (a “Selling Holder”) hereby grants to the parties set forth in this Article V a right of first opportunity with respect to future sales by such Selling Holder of shares of Holder Stock.

Section 5.2 Initial Notice by Selling Holders.

Each time a Selling Holder proposes to offer any Holder Stock, such Selling Holder shall promptly provide a Sale Notice to the Company at least sixty-five (65) days prior to the proposed closing of such sale or transfer. The Company shall provide a copy of such Sale Notice to the Series Preferred Shareholders within five (5) days of its receipt thereof. The Sale Notice shall describe in reasonable detail the proposed sale or transfer including, without limitation, the number of shares of Holder Stock to be sold or transferred, the nature of such sale or transfer, the consideration to be paid, and the name and address of each prospective purchaser or transferee. In the event the sale or transfer is exempted from this Article V pursuant to the provisions of Section 5.5, the Sale Notice shall so state the basis for such exemption.

32

Section 5.3 Participation.

(a) The Company and the Series Preferred Shareholders shall have the right, exercisable upon written notice to such Selling Holder within sixty (60) days after receipt of such Sale Notice by the Series Preferred Shareholders, to elect to purchase or obtain such Holder Stock on the same terms and conditions as set forth in such Sale Notice (the “Right of Opportunity”), subject to the provisions of this Article V. Any party electing to exercise its Right of Opportunity shall state in its written notice whether it intends to purchase (i) the maximum number of shares to which it is entitled under this Section 5.3 or (ii) such lesser number of shares, in which case such party shall state the maximum number of shares it is willing to purchase pursuant to the exercise of its Right of Opportunity. Notwithstanding the foregoing, any Series Preferred Shareholders electing to exercise its right to sell Shares pursuant to Article IV above shall not be eligible to participate in the Right of Opportunity under this Article V and shall waive such Right of Opportunity with respect to the sale of Holder Stock in question. Should no response be received by the Selling Holder from the Company or the Series Preferred Shareholders within sixty (60) days after receipt of the Sale Notice by the Series Preferred Shareholders, any such party failing to provide such notice shall forfeit such Right of Opportunity for the respective sale.

(b) Should the Company make the election not to exercise its Right of Opportunity or should the Company make the election not to purchase the total number of shares of Holder Stock offered by the Selling Holder (such shares not being purchased being referred to herein as the “Unpurchased Shares”), the eligible Series Preferred Shareholders may elect to purchase or obtain, at the price and on the terms specified in such Sale Notice, up to that portion of the Unpurchased Shares that equals the proportion that the number of shares of Common (on an as-if-converted basis) issued and held by the applicable Holder bears to the total number of shares of Common (on as as-if-converted basis) held by all eligible Series Preferred Shareholders electing to exercise their Right of Opportunity.

(c) If all of the Shares referred to in the Sale Notice are not elected to be purchased as provided in this Section 5.3, the Selling Holder may, during the one hundred twenty (120) day period following the expiration of the sixty (60) day period set forth in Section 5.3(a), offer the remaining Unpurchased Shares to a third party at a price not less than and upon terms no more favorable to the offeree than those specified in the Sale Notice. If the Selling Holder does not enter into an agreement with respect to the sale of the remaining Unpurchased Shares within such one hundred twenty (120) day period, or if such agreement in not consummated within thirty (30) days of the execution thereof, the Right of Opportunity shall be deemed to be revived and such Unpurchased Shares shall not be offered unless first reoffered in accordance with this Article V.

33

Section 5.4 Future Participation.

The exercise or non-exercise of the Right of Opportunity hereunder to participate in one or more sales of Holder Stock made by any Selling Holder shall not adversely affect the rights of the Series Preferred Shareholders to participate in subsequent sales of Holder Stock subject to Section 5.1.

Section 5.5 Exempt Transfers.

(a) Holders’ Rights. Notwithstanding the foregoing, the Right of Opportunity shall not apply to (i) any pledge of Holder Stock by a Selling Holder made pursuant to a bona fide loan transaction that creates a mere security interest, (ii) any transfer or bona fide gift to such Selling Holder’s ancestors, descendants (including adopted children) or spouse or to trusts for the benefit of such persons, or (iii) any transfer by a Holder to its partners, members, former partners or former members (or their estates) or Affiliates; provided that (x) such Selling Holder shall inform the Company of such pledge, transfer or gift prior to effecting it, (y) the pledgee, transferee or donee shall furnish the Company with a written agreement to be bound by and comply with all provisions of this Agreement applicable to the Selling Holder, and (z) as a result of such pledge, transfer or gift, the Company would not, in the opinion of counsel to the Company, be rendered subject to the reporting requirements of the 1934 Act. Such pledgee, transferee or donee shall be treated as a “Holder” for purposes of this Agreement, with corresponding rights and obligations.

(b) Holders. Notwithstanding the foregoing, the provisions of Article V shall not apply to the sale of any Holder Stock to the public pursuant to a registration statement filed with, and declared effective by, the SEC under the Act.

Section 5.6 Termination of Rights and Obligations.

The rights and obligations set forth in this Article V shall terminate automatically in the event of a Qualified IPO.

ARTICLE VI

DRAG-ALONG RIGHT

In addition, in the event that a majority in interest of the Series C-3 Shareholders and a majority in interest of the Series C-2 Shareholders enter into an agreement to sell their Shares to a third party in a transaction resulting in a Change in Control, the Holders each agree to sell their Shares to such third party on the same terms and conditions. The provisions of this Article VI shall constitute a shareholders agreement within the meaning of Section 13.1-671.1 of the Virginia Stock Corporation Act and shall be noted conspicuously on the front or back of each certificate for outstanding Shares.
