ARTICLE III.

Registration

Section 3.1 Required Registration

(a) At any time after July 23, 2008, the holders of a majority of the Conversion Shares, may request the Company to register some or all of their Registrable Securities under the Securities Act if the anticipated aggregate price to the public is not less than $8,000,000. Any request for registration (“Registration Request”) shall specify (A) the approximate number of shares of Registrable Securities requested to be registered and (B) the intended method of distribution of such shares.

(b) Within ten days after the receipt of a Registration Request, the Company shall immediately notify all holders of Registrable Securities (other than Registrable Securities held by Key Management and Principal Stockholders) from whom notice has not been received and shall, subject to the limitations of this Section 3.1, effect, as expeditiously as is reasonably possible the registration under the Securities Act, for public sale in accordance with the method of disposition specified in such notice from requesting holders, the number of shares of Registrable Securities specified in such notice (and in all notices received by the Company from other holders within 15 days after the giving of such notice by the Company). In the event that any registration pursuant to this Section 3.1 shall be, in whole or in part, an underwritten public offering of Common Stock, and the managing underwriters advise the Company in their opinion that the number of securities to be included in such registration exceeds the number that can be sold in an orderly manner in such offering within the price range acceptable to the Company, then the number of Registrable Securities included in such offering may be reduced, prorate among the Registrable Securities requested to be included in such offering.

(c) The Company will have the right to select one or more underwriters to manage the offering, subject to the reasonable satisfaction of a majority in interest of the holders of the Conversion Shares initially requesting registration, which approval, if any be required, shall not be unreasonably withheld or delayed; provided, that if the managing underwriter or underwriters shall be the firm or firms that managed the Company’s most recently completed underwritten public offering of Common Stock, such firms shall be deemed acceptable unless a majority in interest of the holders the Conversion Shares initially requesting such registration shall object to such firm or firms for reasons related to the ability of such firm or firms to effectively manage the offering.

(d) The Company shall be obligated to effect a registration pursuant to this Section 3.1 on two occasions only, and shall not be required to effect a registration if the Company delivers notice in writing to the holders of Registrable Securities within 30 days of any Registration Request of the Company’s intent to file a registration statement within 90 days.

(e) The Company shall be entitled to include in any registration statement referred to in this Section 3.1, for sale in accordance with the method of disposition specified by requesting holders, shares of Common Stock to be sold by the Company for its own account but only to the extent that such inclusion will not adversely affect the offering for the account of the holders of Registrable Securities. Except for registration statements on Form X-0, X-0 or any successors thereto, the Company will not file with the Commission any other registration statement with respect to its Common Stock, whether for its own account or that of other stockholders, from the date of receipt of a notice from requesting holders pursuant to this Section 3.1 until the completion of the period of distribution of the registration contemplated thereby.

Section 3.2 Company Registration.

If the Company at any time proposes to register any of its securities under the Securities Act for sale to the public, whether for its own account or for the account of other security holders or both (except with respect to registration statements on Forms X-0, X-0 or another form not available for registering the Registrable Securities for sale to the public), each such time it will give written notice to all holders of outstanding Registrable Securities of its intention so to do. Upon the written request

of any such holder, received by the Company within 15 days after the giving of any such notice by the Company, to register any of its Registrable Securities, the Company will use reasonable best efforts to cause such Registrable Securities to be included in the registration statement proposed to be filed by the Company. In the event that any registration pursuant to this Section 3.2 shall be, in whole or in part, an underwritten public offering of Common Stock, and the managing underwriters advise the Company in their opinion that the number of securities to be included in such registration exceeds the number that can be sold in an orderly manner in such offering within the price range acceptable to the Company, then the number of Registrable Securities included in such offering may be reduced, pro rata among the Registrable Securities requested to be included in such offering; provided, however, that in the case of any underwritten public offering, the number of shares of Conversion Shares included in such offering shall not be reduced below an amount equal to 25% of the total number of shares to be included. Notwithstanding the foregoing provisions, the Company may withdraw any registration statement referred to in this Section 3.2 without thereby incurring any liability to the holders of Registrable Securities.

Section 3.3 Registration on Form S-3. If at any time (i) a holder or holders of Conversion Shares request that the Company file a registration statement on Form S-3 or any successor thereto for a public offering of all or any portion of their Conversion Shares, the reasonably anticipated aggregate price to the public of which would exceed $2,000,000, and (ii) the Company is a registrant entitled to use Form S-3 or any successor thereto to register such shares, then the Company shall, as soon as practicable, use reasonable best efforts to effect and maintain such registration under the Securities Act on Form S-3 or any successor thereto, for public sale in accordance with the method of disposition specified in such notice, the Conversion Shares specified in such notice. The method of disposition may include the registration of such shares “for the shelf” to be offered on a delayed or continuous basis as provided in Rule 415 under the Securities Act. Whenever the Company is required by this Section 3.3 to use reasonable best efforts to effect the registration on behalf of a holder or holders of Conversion Shares, the Company shall notify all other holders of Registrable Securities and provide them with the opportunity to participate in the offering in accordance with Section 3.2 hereof (with any exclusion by underwriters to be pro rata on the basis of the number of shares of Registrable Securities, as defined this Section 3.3 only, requested to be included), and the provisions of paragraphs (c) and (e) of Section 3.1 shall apply to such registration. The Company shall not be required to effect more than two such registrations pursuant to this Section 3.3 in any 12-month period. Registrations effected pursuant to this Section 3.3 shall not be counted as demand registrations effected pursuant to Section 3.1.

Section 3.4 Registration Procedures. If and whenever the Company is required by the provisions of Section 3.1, 3.2 or 3.3 to use reasonable best efforts to effect the registration of any Registrable Securities under the Securities Act, the Company will, as expeditiously as possible:

(a) prepare and file with the Commission a registration statement (which, in the case of an underwritten public offering pursuant to Section 3.1, shall be on Form S-1 or other form of general applicability satisfactory to the managing underwriter selected as therein provided) with respect to such securities and use reasonable best efforts to cause such registration statement to become and remain effective for the period of the distribution

contemplated thereby (determined as hereinafter provided); provided, however, that the Company’s obligation to file a registration statement, or cause such registration statement to become and remain effective, shall be suspended for a period not to exceed 90 days in any 12-month period if in the reasonable good faith judgment of the Company’s Board of Directors it would be seriously detrimental to the Company to effect a registration at such time;

(b) prepare and file with the Commission such amendments and supplements to such registration statement and the related prospectus as may be necessary to keep such registration statement effective for the period specified in paragraph (a) above and comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such registration statement in accordance with the sellers’ intended method of disposition set forth in such registration statement for such period;

(c) furnish to each seller of Registrable Securities and to each underwriter such number of copies of the registration statement and the prospectus forming a part thereof (including each preliminary prospectus) as such persons reasonably may request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such registration statement;

(d) use reasonable best efforts to register or qualify the Registrable Securities covered by such registration statement under the securities or “blue sky” laws of such jurisdictions as the sellers of Registrable Securities or, in the case of an underwritten public offering, the managing underwriter reasonably shall request; provided, however, that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction;

(e) list the Registrable Securities covered by such registration statement with any securities exchange (or quotation system) on which the Common Stock of the Company is then listed (or qualified for inclusion);

(f) immediately (i) notify each seller of Registrable Securities and each underwriter under 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 of which the Company has knowledge as a result of which the prospectus forming a part of 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 in light of the circumstances then existing and (ii) use commercially reasonable efforts to amend or supplement such prospectus in order to cause such prospectus not to include any 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 light of the circumstances then existing;

(g) notify each seller of Registrable Securities, promptly after it shall receive notice thereof, of the time when a registration statement covering such Registrable Securities has become effective or a prospectus forming a part of the registration statement or supplement thereto has been filed;

(h) if the offering is underwritten and at the request of any seller of Registrable Securities, use reasonable best efforts to furnish on the date that Registrable Securities are delivered to the underwriters for sale pursuant to such registration: (i) an opinion dated such date of counsel representing the Company for the purposes of such registration, addressed to the underwriters and to such seller, in form and substance as is customarily given in an underwritten public offering; and (ii) a letter dated such date from the independent public accountants retained by the Company, addressed to the underwriters and to such seller, in form and substance as is customarily given in an underwritten public offering; and

(i) make available for inspection by each seller of Registrable Securities, any underwriter participating in any distribution pursuant to such registration statement, and any attorney or accountant retained by such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such seller, underwriter, attorney or accountant in connection with such registration statement.

(j) For purposes of Section 3.4(a) and 3.4(b), the period of distribution of Registrable Securities in a firm commitment underwritten public offering shall be deemed to extend until each underwriter has completed the distribution of all securities purchased by it, and the period of distribution of Registrable Securities in any other registration shall be deemed to extend until the earlier of the sale of all Registrable Securities covered thereby and 120 days after the effective date thereof.

(k) It shall be a condition precedent to the obligations of the Company to take any action in connection with each registration pursuant to Sections 3.1, 3.2 or 3.3 hereof, that the sellers of Registrable Securities furnish to the Company in writing such information with respect to themselves and the proposed distribution by them as reasonably shall be necessary in order to assure compliance with federal and applicable state securities laws.

(l) In connection with each registration pursuant to Sections 3.1, 3.2 or 3.3 covering an underwritten public offering, the Company shall not be required to include any Registrable Securities in such underwriting unless the holders of such Registrable Securities accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by it (or by other persons entitled to select the underwriters), provided that, such terms shall not provide for indemnification or contribution obligations on the part of the holders of the Registrable Securities materially greater than the obligations of such holders pursuant to Section 3.6(b) hereof.

Section 3.5 Expenses. All expenses incurred by the Company in complying with Sections 3.1, 3.2 and 3.3, including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel and independent public accountants for the Company, fees and expenses (including counsel fees) incurred in connection with complying with state securities or “blue sky” laws, fees of the National Association of Securities Dealers, Inc., transfer taxes, fees of transfer agents and registrars and the reasonable fees and disbursements of one counsel for the sellers of Registrable Securities not to exceed $25,000, but excluding any Selling Expenses, are called “Registration Expenses”. All underwriting discounts

and selling commissions applicable to the sale of Registrable Securities are called “Selling Expenses”. The Company will pay all Registration Expenses in connection with each registration statement under Section 3.1, 3.2 or 3.3; provided, however, that the Company shall not be required to pay for any Registration Expenses of any registration proceeding begun pursuant to Section 3.1 if the registration request is subsequently withdrawn on the written request of the holders of a majority of the Conversion Shares to be registered (in which case all participating holders of Conversion Shares shall bear such expenses pro rata), unless the holders of a majority of the Conversion Shares agree to forfeit their right to one demand registration pursuant to Section 3.1; provided, further that if at the time of such withdrawal, such holders of Conversion Shares have learned of a material adverse change in the Company from that known to such holders at the time of the request and have withdrawn the request with reasonable promptness following disclosure by the Company of or such holders’ otherwise having learned of such material adverse change, then the Company shall pay the Registration Expenses of such holders, and such holders shall not be required to pay any of such expenses and shall not forfeit their right to a demand registration pursuant to Section 3.1. All Selling Expenses in connection with each such registration statement shall be borne by the participating sellers.

Section 3.6 Indemnification and Contribution

(a) In the event of a registration of any of the Registrable Securities under the Securities Act pursuant to Section 3.1, 3.2 or 3.3, the Company will indemnify and hold harmless each seller of such Registrable Securities thereunder, each underwriter of such Registrable Securities thereunder and each other person, if any, who controls such seller or underwriter within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such seller, underwriter or controlling person may become subject under the Securities Act, the Exchange Act, any state securities laws or any rule or regulation promulgated under the Securities Act, Exchange Act or any state securities laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Registrable Securities were registered under the Securities Act, any preliminary prospectus, final prospectus or “free writing prospectus” (as defined pursuant to Rule 405 of the Securities Act) relating thereto, or the Time of Sale Information, each as amended or supplemented, if applicable, (ii) arise out of or are based upon 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) arise out of or are based on any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities laws or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities laws, and will reimburse each such seller, each such underwriter and each such controlling person 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 Company will not be liable to any such indemnitee (i) for any 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, conditioned or delayed), provided that, any settlement effected without the consent of the Company shall not relieve the Company from any liability which it may have to such indemnified party for such damage other than under this Section 3.6, (ii) if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or

alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such indemnitee in writing specifically for use in such registration statement or prospectus, or (iii) if and to the extent that, in the case of a sale directly by such holder of Registrable Securities (including a sale of such Registrable Securities through any underwriter retained by such holder of Registrable Securities to engage in a distribution solely on behalf of such holder of Registrable Securities), such untrue statement or alleged untrue statement or omission or alleged omission was contained in a preliminary prospectus and corrected in a final or amended prospectus, and such holder of Registrable Securities failed to deliver a copy of the final or amended prospectus at or prior to the confirmation of the sale of the Registrable Securities to the Person asserting any such loss, claim, damage or liability in any case where such delivery is required by the Securities Act or any state securities laws, provided that, notice of the filing of such final or amended prospectus was properly delivered by the Company pursuant to Section 3.4(g).

(b) In the event of a registration of any of the Registrable Securities under the Securities Act pursuant to Section 3.1, 3.2 or 3.3, each seller of such Registrable Securities thereunder, severally and not jointly, will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of the Securities Act, each officer of the Company who signs the registration statement, each director of the Company, each underwriter and each person who controls any underwriter within the meaning of the Securities Act, against all losses, claims, damages or liabilities, joint or several, to which the Company or such officer, director, underwriter or controlling person may become subject under the Securities Act, the Exchange Act, any state securities laws or any rule or regulation promulgated under the Securities Act or any state securities laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement under which such Registrable Securities were registered under the Securities Act, any preliminary prospectus, final prospectus or “free writing prospectus” (as defined pursuant to Rule 405 of the Securities Act) relating thereto, or the Time of Sale Information, each as amended or supplemented, if applicable, or arise out of or are based upon 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, and will reimburse the Company and each such officer, director, underwriter and controlling person 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 such seller will be liable hereunder in any such case if and only to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such seller, as such, furnished in writing to the Company by such seller specifically for use in such registration statement or prospectus; and provided, further, however, that the liability of each seller hereunder shall be limited to the proportion of any such loss, claim, damage, liability or expense which is equal to the proportion that the public offering price of the shares sold by such seller under such registration statement bears to the total public offering price of all securities sold thereunder, but not in any event to exceed the net proceeds (after deduction of underwriting discounts and other Selling Expenses) to such seller from the sale of Registrable Securities covered by such registration statement.

(c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 3.6 and shall only relieve it from any liability which it may have to such indemnified party under this Section 3.6 if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel mutually satisfactory to the parties, and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 3.6 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred. 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 which 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 of such claim or litigation. The indemnifying party also shall be responsible for the expenses of such defense if the indemnifying party does not elect to assume such defense.

(d) In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any holder of Registrable Securities exercising rights under this Agreement, or any controlling person of any such holder, makes a claim for indemnification pursuant to this Section 3.6 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 3.6 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any such selling holder or any such controlling person in circumstances for which indemnification is provided under this Section 3.6; then, and in each such case, the Company and such holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) 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, as well as any other relevant equitable considerations. The relative fault of the parties 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; provided, however, that, in any such case, (A) no such holder will be required to contribute, when added to any amounts paid pursuant to Section 3.6(c), an amount in excess of the net proceeds (after deduction of underwriting discounts and other selling expenses) to such seller from the sale of Registrable Securities covered by such registration statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

(e) Any reference in this Section 3.6 to a registration statement shall be deemed to mean the registration statement, as amended at the time of such registration statement’s effectiveness for purposes of Section 11 of the Securities Act (the “Effective Time”), including (i) all documents filed as a part thereof or incorporated or deemed incorporated by reference therein, (ii) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act, to the extent such information is deemed, pursuant to Rule 430B or Rule 430C under the Act, to be part of the registration statement at the Effective Time, and (iii) any registration statement filed to register the offering and sale of securities thereunder pursuant to Rule 462(b) under the Securities Act. Any reference in this Section 3.6 to a prospectus or the Time of Sale Information shall be deemed to refer to and include the documents, if any, incorporated by reference, or deemed to be incorporated by reference, therein, including, unless the context otherwise requires, the documents, if any, filed as exhibits to such incorporated documents. Any reference in this Section 3.6 to the terms “amend,” “amendment,” or “supplement” (or any derivations thereof) with respect to a registration statement, prospectus or the Time of Sale Information shall be deemed to refer to and include the filing of any document under the Exchange Act on or after the date of a registration statement, or the date of a prospectus or such Time of Sale Information, as the case may be, and deemed to be incorporated therein by reference.

(f) The rights and obligations of the parties hereto under this Section 3.6 shall survive the termination of this Agreement.

Section 3.7 Changes in Common Stock. If, and as often as, there is any change in the Common Stock by way of a stock split, stock dividend, combination or reclassification, or through a merger, consolidation, reorganization or recapitalization, or by any other means, appropriate adjustment shall be made in the provisions hereof so that the rights and privileges granted hereby shall continue with respect to the Common Stock as so changed.

Section 3.8 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Registrable Securities to the public without registration, the Company agrees to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities 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; and

(c) furnish to each holder of Registrable Securities forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of such Rule 144 and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as such holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such holder to sell any Registrable Securities without registration.

Section 3.9 Future Registration Rights. In addition to any other restrictions imposed hereby, the Company shall not, except with the consent of the holders of a majority of the Conversion Shares, enter into any agreement with any holder or prospective holder (each, an “Other Holder”) of any securities of the Company that would grant such Other Holder registration rights that would (i) reduce the amount of Conversion Shares that may be registered pursuant to Section 3.1, 3.2 or 3.3 hereof, or (ii) otherwise provide any Other Holder the right to register any securities. In addition, except with the consent of the holders of a majority of the Registrable Securities held by the Acquisition Stockholders, the Company shall not enter into any agreement with any Other Holder that would grant such Other Holder registration rights that are superior to the registration rights of the Acquisition Stockholders hereunder; provided, however, that the foregoing consent of the Acquisition Stockholders shall not be required if Registrable Securities held by the Acquisition Stockholders are treated pari passu with the registrable securities of such Other Holder(s) on a pro rata basis.

Section 3.10 Market Stand Off.

(a) In order to provide for an orderly market for the sale of Common Stock in offerings to which this Agreement relates and to enable the parties hereto to benefit from such an orderly market, each Investor, Principal Stockholder, Acquisition Stockholder and Key Manager hereby agrees that in the event the Company notifies the holders in writing that it intends to file a registration statement for an underwritten public offering of its Common Stock (other than a registration statement described in Section 3.10(f)) with the SEC (a “Filing Notice”), each Investor, Principal Stockholder, Acquisition Stockholder and Key Manager shall not, directly or indirectly sell, offer to sell, contract to sell (including, without limitation, any short sale), grant any option to purchase or otherwise transfer or dispose of any securities of the Company held by it at any time, excluding shares of Common Stock included in such registration, during the period of time commencing on the date of receipt of the Filing Notice (calculated in accordance with the notice provisions hereof) and ending on:

(i) the 31^st day following the date of receipt of the Filing Notice, in the event the Company has not filed a registration statement with the SEC during such time period; or

(ii) in the event the Company files a registration statement with the SEC within the period of time set forth in clause (i) above, then the earlier of (A) the 91^st day following the first filing of such registration statement or (B) the first day on which a lock-up agreement referenced in Section 3.10(b) becomes effective.

The Filing Notice shall include a statement that the anticipated offering price for the Registrable Securities to be included in such offering is not less that $100 million in the aggregate.

(b) In addition to the provisions of Section 3.10(a), each Investor, Principal Stockholder, Acquisition Stockholder and Key Manager also hereby agrees that, during the period of time requested by the managing underwriter(s) in the applicable offering (not to exceed 90 days) following the date of the final prospectus related to a registration statement of the Company filed under the Securities Act, it shall not, to the extent requested by the Company and such underwriter, directly or indirectly sell, offer to sell, contract to sell (including, without limitation, any short sale), grant any option to purchase or otherwise transfer or dispose of any securities of the Company held by it at any time during such period except Common Stock included in such registration.

(c) Notwithstanding the foregoing, an Investor, Principal Stockholder, Acquisition Stockholder or Key Manager shall be allowed to pledge shares of Common Stock pursuant to a bona fide pledge; provided, and only if, (i) the pledgee with respect to such shares executes an agreement substantially in the form attached hereto as Exhibit A and (ii) the shares of Common Stock subject to the pledge are released to the applicable Investor, Principal Stockholder, Acquisition Stockholder or Key Manager no later than the third business day following the closing of the offering to which this Section 3.10 applies.

(d) In order to enforce the covenants set forth in this Section 3.10, the Company may impose stop transfer instructions with respect to the Registrable Securities of each (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period.

(e) Each holder of Conversion Shares hereby agrees that in the event such holder, directly or indirectly, sells, offers to sell, contracts to sell (including, without limitation, any short sale), grants any option to purchase or otherwise transfers or disposes of Registrable Securities, such shares shall be deemed to be Conversion Shares unless such holder delivers to the Company within 10 days after such sale, offer, grant, transfer or disposition a written notice indicating that such shares are not Conversion Shares and shall indicate the manner in which the Registrable Securities proposed to be sold, offered, granted, transferred or disposed of were previously acquired by such holder.

(f) The obligations described in this Section 3.10 shall not apply to a registration (i) relating solely to employee benefit plans on Form S-l or Form S-8 or similar forms which may be promulgated in the future, (ii) relating solely to an SEC Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future or (iii) in which the anticipated offering price to the public for the Registrable Securities to be included in the offering is less than $100 million in the aggregate.

(g) The obligations of each Investor, Principal Stockholder, Acquisition Stockholder and Key Manager under this Section 3.10 shall terminate upon the termination of the Company’s obligations to register Registrable Securities held by such party pursuant to Section 3.11.

(h) The provisions of this Section 3.10 shall apply only to the next offering following the effectiveness of this Amended and Restated Registration Rights Agreement (the “Next Offering”); provided, however, upon written notice signed by the Company and the holders of at least 60% of the then-outstanding Conversion Shares, the provisions of this Section 3.10 may be made applicable to future registrations (other than registrations described in Section 3.10(f)) of the Company.

(i) For purposes of the Next Offering, the parties hereto agree that (i) the form of Lock-up Agreement attached as Exhibit B hereto shall serve as the requested lock-up agreement for purposes of Section 3.10(b) and (ii) the initial lock-up period that is the subject of the lock-up agreement set forth in the foregoing clause (i) for the Next Offering shall not extend beyond March 31, 2008.

(j) Notwithstanding the foregoing, (i) with respect to Section 3.10(a), the Company shall have the authority to allow such exceptions to Section 3.10(a) (and the other provisions of this Section 3.10 applicable thereto, excluding Section 3.10(b)) as it deems advisable; provided that such granting of an exception must be in writing; and provided further that in the event of any release of any securities from the restrictions set forth in Section 3.10(a) the other parties hereto then subject to the restrictions set forth in this Section 3.10(a) shall be released from such restrictions on a pro rata basis; provided, however, there shall be no such pro rata release if it is determined by a majority of the members of the Company’s Board of Directors then in office that there shall be no pro rata release and (ii) with respect to Section 3.10(b), the Company and the managing underwriter(s) in such offering shall have the authority to allow such exceptions to Section 3.10(b) (and the other provisions of this Section 3.10 applicable thereto, excluding Section 3.10(a)) as they together deem advisable; provided that such granting of an exception must be in writing; and provided further that in the event of any release of any securities from the restrictions set forth in Section 3.10(b) the other parties hereto then subject to the restrictions set forth in this Section 3.10(b) shall be released from such restrictions on a pro rata basis; provided, however, there shall be no such pro rata release if it is determined by both the managing underwriter(s) for such offering and a majority of the members of the Company’s Board of Directors then in office that there shall be no pro rata release.

(k) The Company hereby agrees that it will not enter into an underwriting agreement for an offering to which this Section 3.10 applies unless such underwriting agreement contains provisions requiring that the underwriters in such offering abide, to the extent applicable, by the provisions of this Section 3.10.

Section 3.11 Termination of Registration Rights. The obligations of the Company to register Registrable Securities under Section 3.1, 3.2 or 3.3 for a holder of Registrable Securities shall terminate on the earliest to occur of (i) the fifth anniversary of the IPO Date (April 18, 2012) and (ii) the date on which such holder can, in the reasonable opinion of counsel to the Company, sell all shares of his Registrable Securities in a three-month period without registration under the Securities Act pursuant to Rule 144 under the Securities Act; provided, however, that the obligation of the Company to register Registrable Securities under Section 3.1, 3.2 or 3.3 shall continue with respect to any holder while such holder owns more than 1% of the Company’s outstanding Common Stock (as calculated for purposes of paragraph (e) of Rule 144).

Section 6.4 Amendments. This Agreement may not be amended or modified, and no provision hereof may be waived, without the written consent of the Company and the holders of at least 60% of the Conversion Shares held by the Investors; provided, however, that (i) in the event such amendment or waiver adversely affects the rights and/or obligations of the Principal Stockholders, Acquisition Stockholders or Key Management in a different manner than the Investors, such amendment or waiver shall also require the written consent of the holders of a majority of the Common Stock then held by the Principal Stockholders, the Acquisition Stockholders or the holders of a majority of the Common Stock then held by Key Management who are then providing services to the Company as an employee, officer or director, as the case may be, (ii) any amendment or waiver that affects one holder of Conversion Shares in a disproportionately adverse manner as compared to other holders of Conversion Shares must be approved by the disproportionately affected holder of Conversion Shares and (iii) in the event such amendment or waiver adversely affects the registration rights of the Acquisition Stockholders under Article III or the rights of the Acquisition Stockholders under this Section 6.4, such amendment or waiver shall also require the written consent of the holders of a majority of the Registrable Securities then held by the Acquisition Stockholders; and provided further that the Board of Directors shall have the right (a) to amend or modify the list of Key Management on Schedule C hereto from time to time to add or remove certain individuals who become or are no longer employees, officers or directors of the Company; provided, however, that, subject to Section 6.10, the Board shall not remove any individual from Schedule C without the consent of such member of Key Management and (b) to amend or modify the list of Acquisition Stockholders on Schedule D hereto from time to time to add certain entities or individuals that may become stockholders of the Company from time to time in connection with a bona fide business acquisition in which the Company or any subsidiary of the Company is the acquiror. In the event of any addition of a member of Key Management or Acquisition Stockholder who shall have been approved by the Board of Directors, such member of Key Management or Acquisition Stockholder shall become a party to this Agreement upon receipt from such new member of Key Management or Acquisition Stockholder of a fully executed adoption agreement in the form attached as Exhibit C hereto.

Section 6.6 Severability. If any provision of this Agreement shall be held to be illegal, invalid or unenforceable, such illegality, invalidity or unenforceability shall attach only to such provision and shall not in any manner affect or render illegal, invalid or unenforceable any other provision of this Agreement, and this Agreement shall be carried out as if any such illegal, invalid or unenforceable provision were not contained herein.

Section 6.7 Joint Product. This Agreement is the joint product of the Company and the other parties hereto and each provision hereof and thereof has been subject to

the mutual consultation, negotiation and agreement of the Company and the other parties hereto and shall not be construed against any party hereto.

Section 6.8 Termination of Prior Agreement. The parties hereto agree that the Prior Agreement is hereby amended and restated and shall be of no further force or effect.

Section 6.10 Removal of Key Management. As set forth in Section 6.4, as a general matter Key Manager may not be removed from this Agreement without the written consent of such Key Manager. Notwithstanding the foregoing, a Key Manager may be removed from this Agreement by the affirmative consent of a majority of the Company’s Board of Directors then in office in the event such Key Manager’s service with the Company is terminated (i) by the Company for “Cause” as such term is defined in the employment agreement between the Company and such Key Manager or, if there shall be no such employment agreement or if such employment agreement does not contain such defined term, then as such term is defined in the Company’s 2006 Long-term Incentive Plan or (ii) by the Key Manager other than for “Good Reason” as such term is defined in the employment agreement between the Company and such Key Manager or, if there shall be no such employment agreement or if such employment agreement does not contain such defined term, then as such term is defined in the Company’s 2006 Long-term Incentive Plan; provided, however, if at the time of the proposed removal of a Key Manager by the Company’s Board of Directors pursuant to this Section 6.10, such Key Manager is subject to the transfer restrictions set forth in Section 3.10(b), then the Key Manager shall remain a party to this Agreement and such removal shall not be effective until the earlier of (a) the release of such Key Manager from such transfer restrictions or (b) the termination of such period in accordance with the agreement between the managing underwriters and the Key Manager.
