Registration Rights

Section 3.01 Demand Registrations.

(a) Requests for Registration. At any time after the date of this Agreement, subject to the conditions set forth herein, each Investor shall be entitled to make, on its own behalf or on behalf of any of its Affiliates, a written request of the Company (a “Demand”) for registration under the Securities Act of all or any portion of the Registrable Securities owned by such Investor (or such Investor’s Affiliates) (a “Demand Registration”). The Investor making such Demand (the “Demanding Investor”) shall give written notice (a “Demand Notice”) to the Company and to the other Investor specifying: (i) the Demanding

Investor’s intent to exercise a Demand; (ii) the aggregate number of Registrable Securities requested to be registered, provided that such Registrable Securities must have an aggregate Fair Market Value of at least $10,000,000; and (iii) the intended method of distribution in connection with such Demand Registration to the extent then known. Within ten (10) business days of receipt of a Demand Notice, the other Investor, should it wish to participate in the Demand Registration, shall give written notice (a “Demand Participation Notice”) to the Company and the Demanding Investor specifying the aggregate number of Registrable Securities that such Investor, on its own behalf or on behalf of any of its Affiliates, wishes to be included in the Demand Registration. Participation by such Investor in such Demand Registration pursuant to a Demand Participation Notice shall not be counted as a Demand of such Investor. Subject to Section 3.01(f), the Company shall include in the Demand Registration all Registrable Securities requested to be included in such Demand Registration by the Demanding Investor and the other Investor, as set forth in the Demand Participation Notice.

(b) Number of Demands. Each Investor shall be entitled to four (4) Demand Registrations.

(c) Satisfaction of Obligations. Subject to the provisions of Section 3.03, a registration shall not be treated as a permitted Demand for a Demand Registration until (i) the applicable registration statement under the Securities Act has been filed with the Commission with respect to such Demand Registration (which shall include any registration statement that is not withdrawn by holders of Registrable Securities in the circumstances contemplated by Section 3.03); and (ii) such registration statement shall have been maintained continuously effective for a period of at least one hundred eighty (180) days or, in the case of a registration statement registering securities pursuant to Rule 415 under the Securities Act, until all securities registered under such registration statement are sold.

(d) Availability of Short Form Registrations. The Company shall use its commercially reasonable efforts to comply with the requirements for use of short form registration for the sale of Registrable Securities under the Securities Act.

(e) Restrictions on Demand Registrations. The Company shall not be obligated (i) in the case of a Demand Registration, to maintain the effectiveness of a registration statement under the Securities Act for a period of at least 180 days or, in the case of a registration statement registering securities pursuant to Rule 415 under the Securities Act, until all securities registered under such Demand Registration are sold; or (ii) to effect any Demand Registration requested by an Investor within one hundred eighty (180) days of the effective date of (A) a registration in which such Investor, on its own behalf or on behalf of any of its Affiliates, exercised “piggyback” rights pursuant to Section 3.02 hereof (provided that, with respect to such a registration in which such piggyback rights were exercised, such Investor was permitted to include in such registration at least twenty-five percent (25%) of the Registrable Securities that such Investor and its Affiliates sought to include therein) or (B) any other Demand Registration. In addition, the Company shall be entitled to postpone (upon written notice to each Investor) for up to ninety (90) days the filing or the effectiveness of a registration statement in respect of a Demand (but no more than once in any period of twelve (12) consecutive months) if the Board determines in good faith and in its reasonable judgment that effecting the Demand Registration in respect of such Demand would have a material adverse effect on any proposal or plan by the

Company to engage in any debt or equity offering, material acquisition, or disposition of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer, or other similar transaction or otherwise would be materially detrimental to the Company. In the event of a postponement by the Company of the filing or effectiveness of a registration statement in respect of a Demand, the Demanding Investor shall have the right to withdraw such Demand in accordance with Section 3.03 hereof.

(f) Participation in Demand Registrations. Except with the prior written consent of the Demanding Investor, the Company may not include any securities to be sold for the Company’s account or for the account of other Persons that are not holders of Registrable Securities, other than the other Investor and its Affiliates, in a Demand Registration. If, in connection with a Demand Registration, any managing underwriter advises the Company and the Demanding Investor that, in its opinion, the inclusion of all the Registrable Securities and, if authorized pursuant to this Article III, other securities of the Company, in each case, sought to be registered in connection with such Demand Registration would adversely affect the marketability of the Registrable Securities sought to be sold pursuant thereto, then the Company shall include in the registration statement applicable to such Demand Registration only such securities as the Company, the Demanding Investor, and the other Investor are advised by such underwriter can be sold without such an effect (the “Maximum Demand Number”), as follows and in the following order of priority:

(i) first, the number of Registrable Securities sought to be registered by the Demanding Investor, on its own behalf or on behalf of any of its Affiliates, pursuant to such Demand and the number of Registrable Securities, if any, sought to be registered by the other Investor, on its own behalf or on behalf of any of its Affiliates, pursuant to a Demand Participation Notice; provided, however, that, in the event that the aggregate number of Registrable Securities to be sold pursuant to this clause (i) exceeds the Maximum Demand Number, then the number of Registrable Securities to be registered by each of the Demanding Investor and the other Investor shall be reduced pro rata in proportion to the number of Registrable Securities sought to be registered by each such Investor such that the total number of Registrable Securities to be registered equals the Maximum Demand Number; and

(ii) second, and only if the number of Registrable Securities to be included under clause (i) above is less than the Maximum Demand Number, the number of securities sought to be included by the Company, which in the aggregate, when added to the number of securities to be included pursuant to clause (i) above, equals the Maximum Demand Number; and

(iii) third, and only if the number of Registrable Securities to be included under clauses (i) and (ii) above is less than the Maximum Demand Number, the number of securities sought to be sold for the account of other Persons that the Company is obligated to register pursuant to written contractual arrangements with such Persons, pro rata in proportion to the number of securities sought to be sold by such Persons, which in the aggregate, when added

to the number of securities to be included pursuant to clauses (i) and (ii) above, equals the Maximum Demand Number.

(g) Selection of Underwriters. If the Demanding Investor requests that such Demand Registration be an underwritten offering, then the Demanding Investor shall select a nationally recognized underwriter or underwriters to manage and administer such offering, such underwriter or underwriters, as the case may be, to be subject to the approval of the Company and the other Investor (to the extent such other Investor has delivered a Demand Participation Notice), which approval shall not be unreasonably withheld or delayed.

(h) Other Registrations. If the Company has received a Demand and if the applicable registration statement in respect of such Demand has not been withdrawn or abandoned, the Company shall not file or cause to be effected any other registration of any of its equity securities or securities convertible or exchangeable into or exercisable for its equity securities under the Securities Act (other than a registration relating to the Company’s employee benefit plans, exchange offers by the Company, or a merger or acquisition of a business or assets by the Company, including, without limitation, a registration on Form S-4 or Form S-8 or any successor form), whether on its own behalf or at the request of any holder or holders of such securities, until a period of at least ninety (90) days has elapsed from the effective date of any Demand Registration, unless a shorter period of time is approved by the Demanding Investor. Notwithstanding the foregoing, the Company shall be entitled to postpone any such Demand Registration and may file or cause to be effected such other registration in accordance with the terms of Section 3.01(e) hereof.

Section 3.02 Piggyback Registrations.

(a) Right to Piggyback. Whenever the Company proposes to register any shares of its Common Stock or Common Stock held by any stockholders of the Company under the Securities Act (other than a registration under Regulation A or relating to the Company’s employee benefit plans, exchange offers by the Company, or a merger or acquisition of a business or assets by the Company, including, without limitation, a registration on Form S-4 or Form S-8 or any successor form) (a “Piggyback Registration”), the Company shall give each of the Investors prompt written notice thereof (but not less than ten (10) business days prior to the filing by the Company with the Commission of any registration statement with respect thereto). Such notice (a “Piggyback Notice”) shall specify the number of securities proposed to be registered, the proposed date of filing of such registration statement with the Commission, the proposed means of distribution, the proposed managing underwriter or underwriters (if any and if known), and a good faith estimate by the Company of the proposed minimum offering price of such securities. Upon the written request of an Investor, on its own behalf or on behalf of any of its Affiliates, given to the Secretary of the Company within ten (10) business days of the receipt by such Investor of the Piggyback Notice requesting that the Company include in such registration Registrable Securities owned by such Investor or its Affiliates in an amount equal to or greater than the Requisite Amount (which written request shall specify the number of Registrable Securities intended to be disposed of by such Investor and its Affiliates and the intended method of distribution thereof), the Company shall include in such registration all Registrable Securities with respect to which the Company has received such written requests for inclusion, in accordance with the terms hereof.

(b) Priority on Piggyback Registrations. If, in connection with a Piggyback Registration, any managing underwriter (or, if such Piggyback Registration is not an underwritten offering, a nationally recognized independent underwriter selected by the Company) advises the Company and the holders of the Registrable Securities to be included in such Piggyback Registration, that, in its opinion, the inclusion of all the securities sought to be included in such Piggyback Registration by the Company, by any Persons other than the Investors who have sought to have shares registered thereunder pursuant to rights to demand (other than pursuant to so-called “piggyback” or other incidental or participation registration rights) such registration (such demand rights, being “Other Demand Rights” and such other Persons, being “Other Demanding Sellers”), by any holders of securities (including the Investors) seeking to sell such securities in such Piggyback Registration (“Piggyback Sellers”), in each case, if any would materially adversely affect the marketability of the securities sought to be sold pursuant thereto, then the Company shall include in the registration statement applicable to such Piggyback Registration only such securities as the Company, the Other Demanding Sellers, and the Piggyback Sellers are so advised by such underwriter can be sold without such an effect (the “Maximum Piggyback Number”), as follows and in the following order of priority:

(i) if the Piggyback Registration is an offering on behalf of the Company and not a Demanding Investor pursuant to Section 3.01 hereof or any Person exercising Other Demand Rights (whether or not other Persons seek to include securities therein pursuant to so-called “piggyback” or other incidental or participatory registration rights) (a “Primary Offering”), then (A) first, such number of securities to be sold by the Company as the Company, in its reasonable judgment and acting in good faith and in accordance with sound financial practice, shall have determined; and (B) second, if the number of securities to be included under clause (A) above is less than the Maximum Piggyback Number, pro rata in proportion to the securities sought to be registered by all the Piggyback Sellers which in the aggregate, when added to the number of securities to be registered under clause (A) above, equals the Maximum Piggyback Number; and

(ii) if the Piggyback Registration is an offering other than pursuant to a Primary Offering or a Demand Registration, then (A) first, such number of securities sought to be registered by each Other Demanding Seller, pro rata in proportion to the number of securities sought to be registered by all such Other Demanding Sellers; and (B) second, if the number of securities to be included under clause (A) above is less than the Maximum Piggyback Number, the number of securities sought to be registered by each Piggyback Seller, pro rata in proportion to the securities sought to be registered by all the Piggyback Sellers, which in the aggregate, when added to the number of securities to be registered under clause (A) above, equals the Maximum Piggyback Number; and (C) third, if the number of securities to be included under clauses (A) and (B) above is less than the Maximum Piggyback Number, the number of securities to be sold by the Company for its own account, which in the aggregate, when added to the number of securities to be registered under clauses (A) and (B) above, equals the Maximum Piggyback Number.

(c) Withdrawal by the Company. If, at any time after giving written notice of its intention to register any of its securities as set forth in this Section 3.02 and prior to the time the registration statement filed in connection with such registration is declared effective, the Company shall determine not to go forward with a Primary Offering, the Company may, at its election, give written notice of such determination to each Investor and thereupon shall be relieved of its obligation to register any Registrable Securities in connection with such particular withdrawn or abandoned registration (but not from its obligation to pay the Registration Expenses in connection therewith as provided herein).

Section 3.03 Withdrawal Rights. Any Investor that has, on its own behalf or on behalf of any of its Affiliates, notified or directed the Company to include any Registrable Securities in a registration statement under the Securities Act shall have the right to withdraw any such notice or direction with respect to any or all of the Registrable Securities designated for registration thereby by giving written notice to such effect to the Company prior to the effective date of such registration statement. In the event of any such withdrawal, the Company shall not include such Registrable Securities in the applicable registration, and such Registrable Securities shall continue to be Registrable Securities hereunder. No such withdrawal shall affect the obligations of the Company with respect to the Registrable Securities not so withdrawn; provided that in the case of a Demand Registration, if such withdrawal shall reduce the number of Registrable Securities sought to be included in such registration below $10,000,000 of aggregate Fair Market Value as of such date, then the Company shall as promptly as practicable give each holder of Registrable Securities sought to be registered notice to such effect, referring to this Agreement and summarizing this Section 3.03, and within five (5) business days of the effectiveness of such notice either the Company or the holders of a majority of the Registrable Securities sought to be registered may, by written notices made to each holder of Registrable Securities sought to be registered and the Company, elect that such registration statement not be filed or, if theretofore filed, be withdrawn. During such period of five (5) business days, the Company shall not file such registration statement if not theretofore filed, or, if such registration statement has been theretofore filed, the Company shall not seek, and shall use its best efforts to prevent, the effectiveness thereof. Any Demand Registration withdrawn in accordance with an election by the Demanding Investor subsequent to the effectiveness of the applicable Demand Registration Statement shall be counted as a Demand Registration unless such Demanding Investor reimburses the Company for its reasonable out-of-pocket expenses related to the preparation and filing of such registration statement (in which event such registration statement shall not be counted as a Demand Registration hereunder).

Section 3.04 Holdback Agreements. Each Investor agrees not to effect any public sale or distribution (including sales pursuant to Rule 144 (or any successor provision) promulgated under the Securities Act) of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, during the twenty (20) day period prior to the date on which the Company intends to commence a Public Offering (provided the Investors are notified in writing of such commencement date) through the ninety (90) day period immediately following the effective date of any such Public Offering (except as part of such registration), or, if later, the ninety (90) day period immediately following the execution date of any underwriting agreement with respect thereto.

Section 3.05 Registration Procedures.

(a) Whenever the Investors have, on their own behalf or on the behalf of any of their respective Affiliates, requested that any Registrable Securities be registered pursuant to this Agreement, the Company (subject to its right to withdraw such registration as contemplated by Section 3.02(c)) shall use commercially reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and, in connection therewith, the Company shall:

(i) use commercially reasonable efforts to (A) register the Registrable Securities on Form S-3 or another available short form registration statement, to the extent permitted under the Securities Act and the rules and regulations thereunder, (B) cause the registration statement to remain effective for a continuous period of not less than 180 days (or, if earlier, until all of the Registrable Securities included in such registration statement have been sold thereunder), subject to Section 3.05(c), and (C) obtain the withdrawal of any order suspending the registration or qualification (or the effectiveness thereof) or suspending or preventing the use of any related prospectus in any jurisdiction with respect thereto;

(ii) promptly notify each seller of Registrable Securities of each of (A) the filing and effectiveness of the registration statement and prospectus and any amendment or supplements thereto, (B) the receipt of any comments from the Commission or any state securities law authorities or any other governmental authorities with respect to any such registration statement or prospectus or any amendments or supplements thereto, and (C) any oral or written stop order with respect to such registration, any suspension of the registration or qualification of the sale of such Registrable Securities in any jurisdiction, or any initiation or threatening of any proceedings with respect to any of the foregoing;

(iii) furnish to each seller of Registrable Securities, the underwriters, and the sales or placement agent, if any, and counsel for each of the foregoing, a conformed copy of such registration statement and each amendment and supplement thereto (in each case, including all exhibits thereto and documents incorporated by reference therein) and such additional number of copies of such registration statement, each amendment, and supplement thereto (in such case without such exhibits and documents), the prospectus (including each preliminary prospectus) included in such registration statement, and prospectus supplements and all exhibits thereto and documents incorporated by reference therein, and such other documents as such seller, underwriter, agent, or counsel may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

(iv) use commercially reasonable efforts to register or qualify such Registrable Securities under such securities or “blue sky” laws of such jurisdictions as the holders of Registrable Securities reasonably request and do any and all other acts and things that may be reasonably necessary or advisable to enable the holders of Registrable Securities to consummate the disposition in such jurisdictions of the Registrable Securities owned by such holders and keep such

registration or qualification in effect for so long as the registration statement remains effective under the Securities Act (provided that the Company shall not be required to (x) qualify generally to do business in any jurisdiction in which it would not otherwise be required to qualify but for this paragraph, (y) subject itself to taxation in any such jurisdiction in which it would not otherwise be subject to taxation but for this paragraph, or (z) consent to the general service of process in any jurisdiction in which it would not otherwise be subject to general service of process but for this paragraph);

(v) notify each seller of such Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act and the rules and regulations thereunder, upon the discovery that, or of the happening of any event as a result of which, the registration statement covering such Registrable Securities, as then in effect, contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or any fact necessary to make the statements therein not misleading, and promptly prepare and furnish to each such seller a supplement or amendment to the prospectus contained in such registration statement so that such Registration Statement shall not, and such prospectus as thereafter delivered to the purchasers of such Registrable Securities shall not, contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or any fact necessary to make the statements therein not misleading;

(vi) use commercially reasonable efforts to cause all such Registrable Securities to be listed on any national securities exchange or established over-the-counter market on which or through which similar securities of the Company are then listed or traded and, if not so listed or traded, to use commercially reasonable efforts to cause such Registrable Securities to be listed on The Nasdaq Stock Market or to be listed on an automated quotation system and to secure designation of all such Registrable Securities covered by such registration statement as an “NMS Security” within the meaning of Regulation NMS under the Exchange Act;

(vii) provide and cause to be maintained a transfer agent and registrar for all such Registrable Securities covered by such registration statement not later than the effective date of such registration statement;

(viii) make available for inspection by any seller of Registrable Securities and any attorney, accountant, or other agent retained by any such seller or underwriter all financial and other records, pertinent corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees, attorneys, and independent accountants to supply all information reasonably requested by any such sellers, attorneys, accountants, or agents in connection with such registration statement. Information that the Company determines, in good faith, to be confidential shall not be disclosed by such Persons unless (x) the disclosure of such information is necessary to avoid or correct a misstatement or omission in such registration statement, or (y) the

release of such information is ordered pursuant to a subpoena or other order from a court of competent jurisdiction. Each seller of Registrable Securities agrees, on its own behalf and on behalf of all its accountants, attorneys, and agents, that the information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Company unless and until such is made generally available to the public. Each seller of Registrable Securities further agrees, on its own behalf and on behalf of all its accountants, attorneys, and agents, that it will, upon learning that disclosure of such information is sought in a court of competent jurisdiction, give notice to the Company and allow the Company, at the Company’s expense, to undertake appropriate action to prevent disclosure of the information deemed confidential;

(ix) use commercially reasonable efforts to comply with all applicable laws related to such registration statement and offering and sale of securities and all applicable rules and regulations of governmental authorities in connection therewith (including, without limitation, the Securities Act and the Exchange Act) and make generally available to its security holders as soon as practicable (but in any event not later than fifteen (15) months after the effectiveness of such registration statement) an earnings statement of the Company and its subsidiaries complying with Section 11(a) of the Securities Act;

(x) permit any Investor, which Investor, in its sole and exclusive judgment, might be deemed to be an underwriter or controlling Person of the Company, to participate in the preparation of such registration statement and to require the insertion therein of material, furnished to the Company in writing, that in the reasonable judgment of such holder and such holder’s counsel should be included; and

(xi) use commercially reasonable efforts to furnish to each seller of Registrable Securities a signed counterpart of (x) an opinion of counsel for the Company and (y) a “comfort” letter signed by the independent public accountants who have certified the Company’s financial statements included or incorporated by reference in such registration statement, covering such matters with respect to such registration statement and, in the case of the accountants’ comfort letter, with respect to events subsequent to the date of such financial statements, as are customarily covered in opinions of issuer’s counsel and in accountants’ comfort letters delivered to the underwriters in underwritten public offerings of securities for the account of, or on behalf of, an issuer of common stock, such opinion and comfort letters to be dated the date of such opinions and comfort letters are customarily dated in such transactions, and covering in the case of such legal opinion, such other legal matters and, in the case of such comfort letter, such other financial matters, as the holders of a majority of the Registrable Securities being sold may reasonably request.

(b) Underwriting. Without limiting any of the foregoing, in the event that the offering of Registrable Securities is to be made by or through an underwriter, the

Company shall enter into an underwriting agreement with a managing underwriter or underwriters containing representations, warranties, indemnities, and agreements customarily included (but not inconsistent with the agreements contained herein) by an issuer of common stock in underwriting agreements with respect to offerings of common stock for the account of, or on behalf of, such an issuer. In connection with the sale of Registrable Securities hereunder, any seller of such Registrable Securities may, at its option, require that any and all representations and warranties by, and indemnities and agreements of, the Company to or for the benefit of such underwriter or underwriters (or which would be made to or for the benefit of such an underwriter or underwriters if such sale of Registrable Securities were pursuant to a customary underwritten offering) be made to and for the benefit of such seller and that any or all of the conditions precedent to the obligations of such underwriter or underwriters (or which would be so for the benefit of such underwriter or underwriters under a customary underwriting agreement) be conditions precedent to the obligations of such seller in connection with the disposition of its securities pursuant to the terms hereof. In connection with any offering of Registrable Securities registered pursuant to this Agreement, the Company shall (x) furnish to the underwriter, if any (or, if no underwriter, the sellers of such Registrable Securities), unlegended certificates representing ownership of the Registrable Securities being sold, in such denominations as requested and (y) instruct any transfer agent and registrar of the Registrable Securities to release any stop transfer order with respect thereto.

(c) Return of Prospectuses. Each seller of Registrable Securities hereunder agrees that upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3.05(a)(v), such seller shall forthwith discontinue such seller’s disposition of Registrable Securities pursuant to the applicable registration statement and prospectus relating thereto until such seller’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 3.05(a)(v) and, if so directed by the Company, deliver to the Company all copies, other than permanent file copies, then in such seller’s possession of the prospectus current at the time of receipt of such notice relating to such Registrable Securities. In the event the Company shall give such notice, the one hundred and eighty (180) day period during which such registration statement must remain effective pursuant to Section 3.05(a)(i) of this Agreement (or such shorter period as permitted by Section 3.05(a)(i)) shall be extended by the number of days during the period from the date of giving of a notice regarding the happening of an event of the kind described in Section 3.05(a)(v) to the date when all such sellers shall receive such a supplemented or amended prospectus and such prospectus shall have been filed with the Commission.

Section 3.06 Registration Expenses. All expenses incident to the Company’s performance of, or compliance with, its obligations under this Agreement, including, without limitation, all registration and filing fees, all fees and expenses of compliance with securities and “blue sky” laws (including, without limitation, the fees and expenses of counsel for underwriters or placement or sales agents in connection therewith), all printing and copying expenses, all messenger and delivery expenses, all fees and expenses of underwriters and sales and placement agents in connection therewith (excluding discounts and commissions of such underwriters or placement agents), all fees and expenses of the Company’s independent certified public accountants and counsel (including, without limitation, with respect to “comfort” letters and opinions) (collectively, the “Registration Expenses”) shall be borne by the Company. Notwithstanding the foregoing, all underwriting discounts and commissions allocable to each

Investor selling, or effecting the sale of, Registrable Securities on its own behalf or on behalf of any of its Affiliates shall be borne by such Investor. The Company shall not be responsible for the fees and expenses of any additional counsel, or any of the accountants, agents, or experts retained by the Investors in connection with the sale of Registrable Securities. The Company will pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties, the expense of any annual audit, and the expense of any liability insurance) and the expenses and fees for listing the securities to be registered on each securities exchange and included in each established over-the-counter market on which similar securities issued by the Company are then listed or traded or for listing on any other exchange or automated quotation system.

Section 3.07 Indemnification.

(a) By the Company. The Company agrees to indemnify, to the fullest extent permitted by law, each holder of Registrable Securities being sold, its directors, officers, employees, members, managers, partners, agents, and each other Person, if any, who controls (within the meaning of the Securities Act and the rules and regulations thereunder) such holder against all losses, claims, damages, liabilities, and expenses (including legal fees and expenses and all costs incident to investigation or preparation with respect to such losses, claims, damages, liabilities, and expenses and to reimburse such indemnified Person for such costs as incurred) (collectively, the “Losses”) caused by, resulting from, or relating to any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus, or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or a fact necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished to the Company by or on behalf of such holder in writing expressly for use therein or by such holder’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such holder with a sufficient number of copies of the same and notified such holder of such obligation. In connection with an underwritten offering and without limiting any of the Company’s other obligations under this Agreement, the Company shall indemnify such underwriters, their officers, directors, employees, and agents and each Person who controls (within the meaning of the Securities Act and the rules and regulations thereunder) such underwriters or such an other indemnified Person to the same extent as provided above with respect to the indemnification of the holders of Registrable Securities being sold.

(b) By the Investors. In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder will, if requested, furnish to the Company in writing information regarding such holder’s ownership of Registrable Securities and, to the extent permitted by law, shall indemnify the Company, its directors, and each Person who controls (within the meaning of the Securities Act and the rules and regulations thereunder) the Company against all Losses caused by, resulting from, or relating to any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus, or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is caused by and contained in such information so furnished to the Company in writing by or on

behalf of such holder; provided, however, that each holder’s obligation to indemnify the Company hereunder shall be apportioned between each holder based upon the net amount received by each holder from the sale of Registrable Securities, as compared to the total net amount received by all of the holders of Registrable Securities sold pursuant to such registration statement, no such holder being liable to the Company in excess of such apportionment.

(c) Notice. Any Person entitled to indemnification hereunder shall give prompt written notice to the indemnifying party of any claim with respect to which its seeks indemnification; provided, however, that the failure to give such notice shall not release the indemnifying party from its obligation, except to the extent that the indemnifying party has been materially prejudiced by such failure to provide such notice.

(d) Defense of Actions. In any case in which any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not (so long as it shall continue to have the right to defend, contest, litigate, and settle the matter in question in accordance with this paragraph) be liable to such indemnified party hereunder for any legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation, supervision, and monitoring (unless such indemnified party reasonably objects to such assumption on the grounds that there may be defenses available to it that are different from or in addition to the defenses available to such indemnifying party, in which event the indemnified party shall be reimbursed by the indemnifying party for the expenses incurred in connection with retaining separate legal counsel). An indemnifying party shall not be liable for any settlement of an action or claim effected without its consent. The indemnifying party shall lose its right to defend, contest, litigate, and settle a matter if it shall fail diligently to contest such matter (except to the extent settled in accordance with the next following sentence). No matter shall be settled by an indemnifying party without the consent of the indemnified party (which consent shall not be unreasonably withheld).

(e) Survival. The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified Person and will survive the transfer of the Registrable Securities and the termination of this Agreement.

(f) Contribution. If recovery is not available under the foregoing indemnification provisions for any reason or reasons other than as specified therein, any Person who would otherwise be entitled to indemnification by the terms thereof shall nevertheless be entitled to contribution with respect to any Losses with respect to which such Person would be entitled to such indemnification but for such reason or reasons. In determining the amount of contribution to which the respective Persons are entitled, there shall be considered the Persons’ relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and other equitable considerations appropriate under the circumstances. It is hereby agreed that it would

not necessarily be equitable if the amount of such contribution were determined by pro rata or per capita allocation. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not found guilty of such fraudulent misrepresentation. Notwithstanding the foregoing, no Investor (and no Affiliate of such Investor) shall be required to make a contribution in excess of the net amount received by such Investor (or its Affiliate) from the sale of Registrable Securities.
