Registration Rights

2.1 Requested Registration.

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

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

(ii) as soon as practicable, file and use its best efforts to effect such registration (including, without limitation, filing post-effective amendments, appropriate qualifications under applicable blue sky or other state securities laws, and appropriate compliance with the Securities Act) and to permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within twenty (20) days after such written notice from the Company is mailed or delivered.

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

(i) prior to the earlier of (A) the fifth (5th) anniversary of the date of hereof or (B) one hundred eighty (180) days following the effective date of the Company’s Initial Public Offering;

(ii) if the Initiating Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration statement, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than $80,000,000;

-4-

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

(iv) if (A) the registration is initiated by Common Holders holding a sufficient number of Registrable Securities and the Company has effected two (2) such registrations pursuant to this Section 2.1 at the request of the Common Holders, or (B) the registration is initiated by the Investors holding a sufficient number of Registrable Securities and the Company has effect two (2) such registrations pursuant to this Section 2.1, at the request of the Investors; or

(v) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of filing of, and ending on a date one hundred eighty (180) days after the effective date of, a Initial Public Offering; provided that the Company is actively employing in good faith reasonable best efforts to cause such registration statement to become effective, and provided that the Company delivers notice to the Holders of Registrable Securities of its intent to file such registration statement within thirty (30) days of any request for registration by the Initiating Holders.

(c) Deferral. If: (i) in the good faith judgment of the Board, the filing of a registration statement covering the Registrable Securities would be seriously detrimental to the Company and the Board concludes, as a result, that it is essential to defer the filing of such registration statement at such time; and (ii) the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board, it would be detrimental to the Company or its stockholders for such registration statement to be filed in the near future and that it is, therefore, in the best interests of the Company to defer the filing of such registration statement, then (in addition to the limitations set forth in Section 2.1(b)(v) above) the Company shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders, and, provided further, that the Company shall not defer its obligation in this manner more than once in any twelve-month period.

(d) Underwriting. The right of any Holder to include all or any portion of its Registrable Securities in a registration pursuant to this Section 2.1 shall be conditioned upon such Holder’s participation in an underwriting and the inclusion of such Holder’s Registrable Securities to the extent provided herein. If the Company shall request inclusion in any registration pursuant to Section 2.1 of securities being sold for its own account, or if other Holders shall request inclusion in any registration pursuant to Section 2.1, the Initiating Holders shall, on behalf of all Holders, offer to include such securities in the underwriting and such offer shall be conditioned upon the participation of the Company or such other persons in such underwriting and the inclusion of the Company’s and such person’s other securities of the Company and their acceptance of the further applicable provisions of this Section 2 (including Section 2.10). The Company shall (together with all Holders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting by the Company, which underwriters are reasonably acceptable to a majority-ininterest of the Initiating Holders.

Notwithstanding any other provision of this Section 2.1, if the underwriters advise the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, the number of Registrable Securities that may be so included shall be apportioned pro rata among the selling Holders based on the number of Registrable Securities held by all selling Holders or in such other proportions as shall mutually be agreed to by all such selling Holders. In no event shall Registrable Securities held by Holders be excluded from such registration unless all other stockholders’ securities (including securities for the account of the Company) have been first excluded.

-5-

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

2.2 Company Registration.

(a) If the Company shall determine to register any of its securities either for its own account or the account of an Investor, other than a registration pursuant to Section 2.1 or 2.3, a registration relating solely to employee benefit plans, a registration relating to the offer and sale of debt securities, a registration relating to a corporate reorganization or other Rule 145 transaction, a registration on Form S-3 of securities to be offered on a delayed or continuous basis pursuant to Rule 415 of the Securities Act or a registration on any registration form that does not permit secondary sales, the Company will:

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

(ii) use its best efforts to include in such registration (and any related qualification under blue sky laws or other compliance), except as set forth in Section 2.2(b) below, and in any underwriting involved therein, all of such Registrable Securities as are specified in a written request or requests made by any Holder or Holders received by the Company within twenty (20) days after such written notice from the Company is mailed or delivered. Such written request may specify all or a part of a Holder’s Registrable Securities.

(b) Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 2.2(a)(i). In such event, the right of any Holder to registration pursuant to this Section 2.2 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other holders of securities of the Company with registration rights to participate therein distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by the Company.

Notwithstanding any other provision of this Section 2.2, if the underwriters advise the Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the underwriters may (subject to the limitations set forth below) limit the number of Registrable Securities to be included in the registration and underwriting. In no event shall any Registrable Securities be excluded from

-6-

such registration and underwriting unless all other stockholders’ securities have been first excluded. In the event that the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such registration and underwriting, then the Registrable Securities that are included in such registration and underwriting shall be apportioned pro rata among the selling Holders based on the number of Registrable Securities held by all selling Holders or in such other proportions as shall mutually be agreed to by all such selling Holders. Notwithstanding the foregoing, in no event shall the amount of securities of the selling Holders included in the registration and underwriting be reduced below thirty percent (30%) of the total amount of securities included in such registration and underwriting, unless such registration is the Company’s Initial Public Offering, in which case the selling Holders may be excluded entirely if the underwriters make the determination described above and no other stockholders’ securities are included in such registration and underwriting.

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

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

2.3 Registration on Form S-3.

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

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

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

(ii) if the Initiating Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) on Form S-3 at an aggregate price to the public of less than $10,000,000; or

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

-7-

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

2.4 Expenses of Registration. All Registration Expenses incurred in connection with registrations pursuant to Sections 2.1, 2.2 and 2.3 hereof shall be borne by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Sections 2.1 and 2.3 if the registration request is subsequently withdrawn at the request of (i) the Initiating Holders if the holders of Shares are the Initiating Holders, and (ii) the holders of a majority of the Registrable Securities to be registered or because a sufficient number of Holders shall have withdrawn so that the minimum offering conditions set forth in Sections 2.1 and 2.3 are no longer satisfied (in which case all participating Holders shall bear such expenses pro rata among each other based on the number of Registrable Securities requested to be so registered), unless the Holders of a majority of the Registrable Securities and the holders of [two-thirds] of the Shares agree to forfeit their right to a demand registration pursuant to Section 2.1; and provided, further, however, that if at the time of such withdrawal, the Holders have learned of a material adverse change in the condition, business, or prospects of the Company from that known to the Holders at the time of their request and have withdrawn the request with reasonable promptness following disclosure by the Company of such material adverse change, then the Holders shall not be required to pay any of such expenses and shall retain their rights pursuant to Section 2.1 or 2.3 (with such registration proceeding not being counted as a requested registration pursuant to Section 2.1 or 2.3). If the Holders bear the Registration Expenses for any registration proceeding begun pursuant to Section 2.1 and subsequently withdrawn by the Holders registering shares therein, such registration proceeding shall not be counted as a requested registration pursuant to Section 2.1. All Selling Expenses relating to securities registered on behalf of the selling Holders shall be borne pro rata by the selling Holders based on the number of Registrable Securities so registered.

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

(a) keep such registration effective for a period ending on the earlier of the date which is ninety (90) days from the effective date of the registration statement or such time as the Holder or Holders have completed the distribution described in the registration statement relating thereto; provided, however, that such 90-day period shall be extended for a period of time equal to the period the Holder refrains from selling any securities included in such registration at the request of an underwriter of common stock or other securities of the Company.

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

(c) furnish such number of prospectuses, including any preliminary prospectuses, and other documents incident thereto, including any amendment of or supplement to the prospectus, as a Holder from time to time may reasonably request;

-8-

(d) use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdiction as shall be reasonably requested by the Holders; provided, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions;

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

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

(g) cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities issued by the Company are then listed; and

(h) in connection with any underwritten offering pursuant to a registration statement filed pursuant to this Section 2, enter into an underwriting agreement in form reasonably necessary to effect the offer and sale of Common Stock, provided such underwriting agreement contains reasonable and customary provisions, and provided further, that each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement; and

(i) furnish, at the request of any Holder requesting registration of Registrable Securities pursuant to this Section 2, on the date that such Registrable Securities are delivered to the underwriters for sale in connection with a registration pursuant to this Section 2, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date that the registration statement with respect to such securities becomes effective, (i) an opinion, dated such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities and (ii) a letter, dated such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities (to the extent the then-applicable standards of professional conduct permit said letter to be addressed to the Holders).

(c) Each party entitled to indemnification under this Section 2.6 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld), and the Indemnified Party may participate in such defense at such party’s expense; provided, further, 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; and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 2.6, to the extent such failure is not prejudicial. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom.

(d) If the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage, or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations; provided, however, that no contribution by any Holder, when combined with any amounts paid by such Holder pursuant to Section 2.6(b), shall exceed the gross proceeds from the offering received by such Holder. 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. The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 2.6 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above.

(e) The indemnification and contribution provided for under this Agreement shall be in addition to any other rights to indemnification or contribution that any indemnified party may have pursuant to law or contract and shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the transfer of Registrable Securities and the termination or expiration of this Agreement.

-11-

(f) No indemnifying party shall, except with the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

2.7 Information by Holder. Each Holder of Registrable Securities shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification, or compliance referred to in this Section 2.

2.8 Restrictions on Transfer.

(a) The holder of each certificate representing Registrable Securities by acceptance thereof agrees to comply in all respects with the provisions of this Section 2.8. Each Holder agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the Restricted Securities, or any beneficial interest therein, unless and until:

(i) the transferee thereof has executed and delivered to the Company the Adoption Agreement, attached hereto as Exhibit C, agreeing in writing for the benefit of the Company and the other Holders to take and hold such Restricted Securities subject to, and to be bound by, the terms and conditions set forth in this Agreement, including, without limitation, Section 2.6, this Section 2.8 and Section 2.10, and such transferee’s name is added to Exhibit A or Exhibit B as the case may be;

(ii) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; and

(iii) such Holder shall have given prior written notice to the Company of such Holder’s intention to make such disposition and shall have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition, and, if requested by the Company, such Holder shall have furnished the Company, at such Holder’s expense, with (1) an opinion of counsel, reasonably satisfactory to the Company, to the effect that such disposition will not require registration of such Restricted Securities under the Securities Act or (2) a “no action” letter from the Commission to the effect that the transfer of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered by the Holder to the Company. It is agreed that the Company will not require opinions of counsel or “no action” letters for transactions made pursuant to Rule 144.

Notwithstanding the provisions of subsections (a)(ii) and (a)(iii) above, no such registration statement or opinion of counsel or “no action” letter shall be necessary for a transfer by a Holder to any of its Affiliates or by a Holder that is a partnership to a partner of such partnership or a retired partner of such partnership who retires after the date hereof, or to the estate of any such partner or retired partner or the transfer by gift, will or intestate succession of any partner to his or her spouse or to the siblings, lineal descendants or ancestors of such partner or his or her spouse, if the prospective transferee agrees in all such instances in writing to be subject to the terms hereof to the same extent as if he or she were an original Holder hereunder.

-12-

(b) Each certificate representing Registrable Securities shall (unless otherwise permitted by the provisions of this Agreement) be stamped or otherwise imprinted with a legend substantially similar to the following (in addition to any legend required under applicable state securities laws):

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS PURSUANT TO REGISTRATION OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO (1) RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD OF UP TO 180 DAYS IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN AN INVESTOR RIGHTS AGREEMENT, AND (2) VOTING RESTRICTIONS AS SET FORTH IN A VOTING AGREEMENT AMONG THE COMPANY AND THE ORIGINAL HOLDERS OF THESE SHARES, COPIES OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY.

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

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

-13-

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

(a) make and keep public information regarding the Company available as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the effective date that the Company becomes subject to the reporting requirements of the Securities Act or the Exchange Act;

(b) file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act at any time after it has become subject to such reporting requirements; and

(c) so long as a Holder owns any Restricted Securities, make available to the Holder forthwith upon written request a written statement by the Company as to its compliance with the reporting requirements of Rule 144 and of any other reporting requirements of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any such securities without registration.

2.10 Market Stand-Off Agreement. Each Holder hereby agrees that such Holder shall not sell or otherwise transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Common Stock (or other securities) of the Company held by such Holder (other than those included in the registration) during the one hundred eighty (180) day period following the effective date of the Company’s Initial Public Offering. The obligations described in this Section 2.10 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 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions and may stamp each such certificate with the second legend set forth in Section 2.8(b) hereof with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of such one hundred eighty (180) day period. Each Holder agrees to execute a market standoff agreement with said underwriters in customary form consistent with the provisions of this Section 2.10.

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

2.12 Transfer or Assignment of Registration Rights. The rights to cause the Company to register securities granted to a Holder by the Company under this Section 2 may be transferred or assigned by a Holder only to: (a) a transferee or assignee of not less than two percent (2%) of Registrable Securities (as presently constituted and subject to subsequent adjustments for stock splits, stock dividends, reverse stock splits, and the like); (b) an Affiliate of a Holder or a subsidiary, parent, partner, limited partner, retired partner, member or retired member of a Holder; or (c) for individual Holders, such Holder’s family member or trust for the benefit of an individual Holder or Holder’s family member; provided that (i) any such transfer or assignment of Registrable Securities is effected in accordance with the terms of Section 2.8 hereof, and applicable securities laws; (ii) the Company is given written notice prior to said transfer or assignment, stating the name and address of the transferee or assignee and identifying

-14-

the securities with respect to which such registration rights are intended to be transferred or assigned; and (iii) the transferee or assignee of such rights assumes in writing the obligations of such Holder under this Agreement pursuant to the execution and delivery to the Company of the Adoption Agreement, attached hereto as Exhibit C.

2.13 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of the Holders holding [two-thirds] of the outstanding shares of the Registrable Securities held the holders of Shares, or any shares of Common Stock issued upon conversion thereof, enter into any agreement with any holder or prospective holder of any securities of the Company granting such holder or prospective holder any registration rights.

2.14 Termination of Registration Rights. The right of any Holder to request registration or inclusion in any registration pursuant to Section 2.1, 2.2 or 2.3 shall terminate with respect to such Holder on the earlier of (a) such date, on or after the closing of the Company’s Initial Public Offering, on which all shares of Registrable Securities held or entitled to be held upon conversion by such Holder may immediately be sold under Rule 144 during any ninety (90)-day period; and (b) five (5) years after the closing of the Company’s Public Offering.

Section 3

Covenants of the Company

The Company hereby covenants and agrees, as follows:

(i) as soon as practicable after the end of each fiscal year of the Company, and in any event within ninety (90) days after the end of each fiscal year of the Company, an audited consolidated balance sheet of the Company and its subsidiaries as at the end of such fiscal year, and audited consolidated statements of income and cash flows of the Company and its subsidiaries, for such year, prepared in accordance with U.S. generally accepted accounting principles consistently applied, certified by independent public accountants of recognized national standing selected by the Company; and

(ii) as soon as practicable, and in any event within forty-five (45) days after the end of the first, second, and third quarterly accounting periods in each fiscal year of the Company, an unaudited consolidated balance sheet of the Company and its subsidiaries as of the end of each such quarterly period, and unaudited consolidated statements of income and cash flows of the Company and its subsidiaries, for such period, prepared in accordance with U.S. generally accepted accounting principles consistently applied, subject to changes resulting from normal yearend audit adjustments, with the exception that no notes need be attached to such statements and yearend audit adjustments may not have been made.

-15-

3.2 Operating Plan and Budget. The Company shall prepare an annual operating plan and budget (including projected balance sheets and profit and loss and cash flow statements) for this and each upcoming fiscal year presented in a manner consistent with the information provided pursuant to Section 3.1 hereof, and as soon as practicable upon approval or adoption by the Board, the Company will furnish each Significant Holder with the Company’s budget and operating plan for such fiscal year

3.3 Inspection Rights. The Company will afford to each Significant Holder reasonable access during normal business hours (i) to all of the Company’s properties, books and records. Significant Holders may exercise their rights under this Section 3.2 only for purposes reasonably related to their interests under this Agreement and related agreements (including the ability to make copies and take extracts therefrom), and (ii) to discuss the Company’s affairs, finances and accounts with its officers. The rights granted pursuant to this Section 3.2 may not be assigned or otherwise conveyed by any Significant Holder or by any subsequent transferee of any such rights without the prior written consent of the Company.

3.4 Confidentiality. An ything in this Agreement to the contrary notwithstanding, no Holder by reason of this Agreement shall have access to any trade secrets or classified information of the Company. The Company shall not be required to comply with any information rights or inspection rights of Section 3 in respect of any Holder whom the Board reasonably determines to be a competitor or an officer, employee, director or holder of more than ten percent (10%) of a competitor, nor shall the Company be obligated to disclose any information which the Board determines in good faith is attorney-client privileged and should not, therefore, be disclosed. The Company shall not be obligated to disclose details of contracts with, or work performed for, specific customers and other business partners where to do so would violate confidentiality obligations to those parties. Each Holder agrees that it will not use any information received by it pursuant to this Agreement in violation of the Exchange Act or reproduce, disclose or disseminate such information to any other person (other than its employees, agents or partners having a need to know the contents of such information, and its attorneys), except in connection with the exercise of rights under this Agreement, unless the Company has made such information available to the public generally.

3.5 Accounts and Records. 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 generally accepted accounting principles applied on a consistent basis.

3.6 Independent Accountants. The Company will retain independent public accountants of recognized national standing (i.e. PricewaterhouseCoopers, KMPG, Deloitte & Touche, Ernst & Young, or their successors, each a “Nationally Recognized Firm”) who shall certify the Company’s financial statements at the end of each fiscal year. In the event the services of the Nationally Recognized Firm so selected, or any Nationally Recognized Firm hereafter employed by the Company, are terminated, the Company will promptly notify the Significant Holders and will request the Nationally Recognized Firm whose services are terminated to deliver to the

-16-

Significant Holders a letter from such Nationally Recognized Firm setting forth the reasons for the termination of its services. In its notice to the Significant Holders, the Company shall state whether the change of accountants was recommended or approved by the Board or any committee thereof In the event of such termination, the Company will promptly thereafter engage another Nationally Recognized Firm.

3.7 Transactions with Affiliates. The Company shall not, without the approval of the disinterested members of the Board, engage in any loans, leases, contracts or other transactions with any officer, director, or key employee of the Company, or any member of any such person’s immediate family, including the parents, spouse, children, or other relatives of any such person, on terms less favorable than the Company would obtain in a transaction with an unrelated party, as determined in good faith by the Board, except pursuant to the Restated Certificate or the ROFR Agreement.

3.8 Restrictions on Transfer. Unless otherwise approved by the Board, all purchases of shares of Common Stock of the Company after the date of this Agreement shall be pursuant to a form of agreement which provides: (a) for a right of first refusal in favor of the Company (terminable upon the Company’s Initial Public Offering); (b) that any shares of unvested Common Stock may not be transferred by such holder (except for certain estate planning transactions); (c) that no shares of Common Stock may be transferred by such holder during the one hundred eighty (180) day period following the effective date of the Company’s Initial Public Offering; and (d) for no acceleration of vesting of shares of Common Stock unless both (i) control of the Company is transferred and (ii) any repurchase option that relates to the shares of Common Stock is not assumed by the acquiror in such change of control.

The existence, composition, and responsibilities of the Committee may not be changed without the consent of the then current members of the Committee.

Section 4

Right of First Refusal

4.1 Right of First Refusal to Significant Holders. The Company hereby grants to each Significant Holder the right of first refusal to purchase its pro rata share of New Securities (as defined in Section 4.1(a)) which the Company may, from time to time, propose to sell and issue after the date of this Agreement if (A) such New Securities are being offered to the Investors or any of their Affiliates or (B) such New Securities are being sold to one or more third parties not including the Investors or any of their Affiliates for cash at a pre-money equity valuation that values the common stock (on a fully-diluted basis) at less than $5.61178 (as adjusted for any stock split, combination of shares, reorganization, recapitalization, reclassification or other similar event). A Significant Holder’s pro rata share, for purposes of this right of first refusal, is equal to the ratio of: (x) the number of shares of Common Stock owned by such Significant Holder immediately prior to the issuance of New Securities (assuming full conversion of the Shares and exercise of all outstanding convertible securities, rights, options and warrants, directly or indirectly, into Common Stock held by said Significant Holder) to (y) the total number of shares of Common Stock outstanding immediately prior to the issuance of New Securities (assuming full conversion of the Shares and exercise of all outstanding convertible securities, rights, options and warrants, directly or indirectly). Each Significant Holder shall have a right of over-allotment such that if any Significant Holder fails to exercise its right hereunder to purchase its pro rata share of New Securities, the other Significant Holders who exercise their purchase rights hereunder may purchase the non-purchasing Significant Holder(s)’ portion on a pro rata basis (the “Over-Allotment Option”).

(a) “New Securities” shall mean any capital stock (including Common Stock and/or Preferred Stock) of the Company whether now authorized or not, and rights, convertible securities, options or warrants to purchase such capital stock, and securities of any type whatsoever that are, or may become, exercisable or convertible into capital stock; provided that, the term “New Securities” does not include:

(i) the Shares and the Conversion Stock;

(ii) securities issued or issuable to officers, directors, employees of, or consultants to, the Company pursuant to stock grants, option plans, purchase plans, agreements or other employee stock incentive programs or arrangements approved by the Board, or upon exercise of options or warrants granted to such parties pursuant to any such plan or arrangement;

(iii) securities issued upon the conversion or exercise of any outstanding convertible or exercisable securities as of this date of this Agreement;

(iv) securities issued or issuable as a dividend or distribution on Preferred Stock of the Company or pursuant to any event for which adjustment is made pursuant to paragraphs 4(e), 4(f) or 4(g) of the Certificate of Incorporation of the Company;

(v) securities issued pursuant to a registered public offering under the Securities Act;

(vi) securities issued or issuable pursuant to the bona fide acquisition of another corporation by the Company by merger, purchase of substantially all of the assets or other reorganization whereby the Company will own not less than a majority of the voting power of the surviving or successor corporation, which acquisition is approved by the Board;

-18-

(vii) (vii) securities issued or issuable to banks, equipment lessors, other financial institutions, landlords or other providers of goods or services to the Company pursuant to a debt financing, equipment lease, bank credit arrangement or commercial leasing transaction entered into for primarily non-equity financing purposes, or for a lease or other commercial arrangement, each as approved by the Board;

(viii) securities issued to entities in connection with joint ventures, development projects or other strategic transactions, if such issuance is approved by the Board;

(ix) securities of the Company which are otherwise excluded by the affirmative unanimous vote of the Board and are not offered to any existing stockholder of the Company;

(x) securities issued in connection with Section 3.8 hereto, and securities issued upon the exercise thereof; and

(xi) any right, option or warrant to acquire any security convertible into the securities excluded from the definition of New Securities pursuant to subsections (i) through (xi) above.

(b) In the event the Company proposes to undertake an issuance of New Securities, it shall give each Significant Holder written notice of its intention, describing the type of New Securities, and their price and the general terms upon which the Company proposes to issue the same. Each Significant Holder shall have twenty (20) days after any such notice is mailed or delivered to agree to purchase such Significant Holder’s pro rata share of such New Securities and to indicate whether such Significant Holder desires to exercise its Over-Allotment Option for the price and upon the terms specified in the notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased.

(c) In the event the Significant Holders fail to exercise fully the right of first refusal and Over-Allotment Option, if any, within said twenty (20) day period (the “Election Period”), the Company shall have ninety (90) days thereafter to sell or enter into an agreement (pursuant to which the sale of New Securities covered thereby shall be closed, if at all, within thirty (30) days from the date of said agreement) to sell that portion of the New Securities with respect to which the Significant Holders’ right of first refusal option set forth in this Section 4.1 was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice to Significant Holders delivered pursuant to Section 4.1(b). In the event the Company has not sold or entered into an agreement within such ninety (90) day period following the Election Period, or sold within such thirty (30)-day period following the date of said agreement, the Company shall not thereafter issue or sell any New Securities without first again offering such securities to the Significant Holders in the manner provided in this Section 4.1.

4.2 Termination of Right of First Refusal. The right of first refusal granted under this Agreement shall expire upon, and shall not be applicable to, the Company’s Public Offering.
