REGISTRATION RIGHTS AGREEMENT

This Registration Rights Agreement (this “Agreement”) is made as of July 10, 2023 (the “Effective Date”) by and among:

RECITALS

1. As of the date hereof, the Sellers acquired shares of the Company pursuant to the consummation of the transactions contemplated by that certain Equity Purchase Agreement, dated July 1, 2022, as amended from time to time (the “Purchase Agreement”). This Agreement is being entered into in connection therewith.

2. Unless otherwise noted herein, capitalized terms used herein shall have the meanings set forth in Section 5 of this Agreement.

3. This Agreement shall become effective as of the Effective Date.

AGREEMENT

NOW, THEREFORE, the Parties hereby agree as follows:

1.1. Requests for Registration. At any time after the consummation of the Initial Public Offering, each of NIM and Acceleratio may initiate up to one (1) registration of all or part of the respective holder’s Registrable Securities on Form S-1, Form S-2 or any similar or successor long-form registration statement (“Long-Form Registrations”) and, if available, no more than two (2) registrations of all or part of the respective holder’s Registrable Securities on Form S-3 or any similar or successor short-form registration statement (“Short-Form Registrations”); provided,

-1-

that, prior to the first anniversary of the consummation of the Initial Public Offering, NIM and Acceleratio shall not be permitted to initiate a Long-Form Registration unless at such time an Advent Holder (or group thereof) has previously exercised its right to initiate a Long-Form Registration under this Agreement or the Other Registration Rights Agreement (as defined below) at least once, unless otherwise consented to by Advent Holdco.

1.2. Demand Notice. All requests for Demand Registrations shall be made by giving written notice to the Company (a “Demand Notice”). Each Demand Notice shall specify the approximate number of Registrable Securities requested to be registered. Except in connection with an Initial Public Offering, within ten (10) days after receipt of any such Demand Notice, the Company will give written notice of such requested registration to all other Holders and, subject to Section 1.5, will include in such registration (and in all related registrations and qualifications under blue sky laws or in compliance with other registration requirements and in any related underwriting, if any) all Registrable Securities held by any Holder with respect to which the Company has received written requests for inclusion therein within ten (10) Business Days after the delivery of the Company’s notice. In connection with an Initial Public Offering in which Advent or any Advent Holder is participating as a selling stockholder, no later than the date of public filing of a registration statement related to the Initial Public Offering, the Company will give written notice of such requested registration to all other Holders and, subject to Section 1.5, will include in such registration (and in all related registrations and qualifications under blue sky laws or in compliance with other registration requirements and in any related underwriting, if any) all Registrable Securities held by any Holder with respect to which the Company has received written requests for inclusion therein within ten (10) Business Days after the delivery of the Company’s notice.

1.3. Demand Registration Expenses. The Company will pay all Registration Expenses in connection with any registration initiated as a Demand Registration, whether or not it has become effective.

1.4. Short-Form Registrations. Demand Registrations will be Short-Form Registrations whenever the Company is permitted to use any applicable short-form registration statement (unless the managing underwriter(s) of such offering reasonably requests the Company to use a Long-Form Registration in order to sell all of the Registrable Securities requested to be sold). After the Company has become eligible to use a Short-Form Registration, the Company will use its reasonable best efforts to make Short-Form Registrations available for the sale of Registrable Securities. Each of NIM and Acceleratio may require the Company to file any Demand Registration with the SEC in accordance with and pursuant to Rule 415 under the Securities Act (or any successor rule then in effect) (a “Shelf Registration”).

1.5. Priority on Demand Registrations. If a Demand Registration is an underwritten offering and the managing underwriter(s) advises the Company in writing that in its opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering exceeds the number of Registrable Securities and other securities, if any, which can be sold therein without adversely affecting the marketability of the offering, then the Company shall include in such registration, prior to the inclusion of any securities that are not Registrable Securities, the number of Registrable Securities requested by the Holders to be included in such offering that, in the opinion of such underwriter(s), can be sold without adversely

-2-

affecting the marketability of the offering, pro rata among the respective Holders on the basis of the number of Registrable Securities owned by each such Holder, and, in the event that the number of Registrable Securities requested by the Holders is less than the number of securities which can be sold in such offering without adversely affecting the marketability of the offering, only then securities that are not Registrable Securities may be included, pro rata among the respective Holders thereof on the basis of the number of securities owned by each such Holder; provided, that, Advent Holdco agrees that if any Other Holder (other than any Advent Holder) has the contractual right to, and elects to, participate in such offering in an amount in excess of such Other Holder’s pro rata portion as determined hereunder, the number of securities of such Other Holder to be included in such offering will reduce the number of securities permitted to be sold by the Advent Holders (collectively, but allocated among them as determined by Advent Holdco or Advent) in such offering; provided, further, that if such underwriter(s) provide written notice advising in good faith that participation in the offering by any Holder who is, or is an Affiliate of, any employee of the Company or any of its Subsidiaries would materially and adversely affect the marketability of such offering, then Registrable Securities held by one or more such Holders may be excluded (in whole or in part) from such offering, even if such exclusion would not allow such Holders to participate on a pro rata basis with such other Holders.

1.6. Selection of Underwriters.

(a) In the event that Acceleratio or NIM initiates an underwritten offering in connection with a Demand Registration, such initiating Holder may (after consultation with Advent, and if any Advent Holder is participating in such underwritten offering, after consultation with and consent from Advent, such consent not to be unreasonably withheld or delayed) select the underwriter or underwriters to administer such underwritten offering; and

(b) In the event that any Advent Holder (or group thereof) initiates an underwritten offering in connection with a Demand Registration, such Advent Holder (or group thereof) will have the right (after consultation with Acceleratio and NIM) to select the underwriters or underwriters to administer such underwritten offering.

1.7. Other Registration Rights. The Company represents and warrants that it is not a party to, or otherwise subject to, any other agreement granting registration rights to any other Person with respect to any securities of the Company, other than this Agreement and the Registration Rights Agreement by and among the Company and the other parties thereto dated as of March 5, 2021 (as may be amended from time to time in accordance with its terms and this Agreement, the “Other Registration Rights Agreement”). Advent Holdco will not permit the Other Registration Rights Agreement to be amended in any way which would adversely affect the rights of Acceleratio or NIM under this Agreement or under the Other Registration Rights Agreement, and Advent Holdco will not permit any amendment to this Agreement that would adversely affect the rights of Acceleratio or NIM without the prior written consent of Acceleratio and/or NIM, as the case may be. In the event any provision of the Other Registration Rights Agreement with respect to the rights of Acceleratio or NIM is inconsistent with the corresponding provision of this Agreement, this Agreement shall control.

-3-

1.8. Limitation on Demand Registrations. Notwithstanding anything to the contrary contained herein, the Company shall not be obligated to take any action to effect any Demand Registration if a Demand Registration or Piggyback Registration was declared effective or an Underwritten Shelf Takedown was consummated, or any similar such registration or shelf takedown pursuant to the Other Registration Rights Agreement was declared effective or consummated, as applicable, within the preceding ninety (90) days (unless otherwise consented to by the Company).

1.9. Delay in Filing; Suspension of Registration. Notwithstanding anything to the contrary contained herein, if the filing, initial effectiveness or continued use of a Demand Registration at any time would require the Company to make an Adverse Disclosure, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, the Demand Registration (a “Demand Suspension”); provided, however, that the Company shall not be permitted to exercise a Demand Suspension more than once during any twelve (12)-month period for a period not to exceed sixty (60) days. In the case of a Demand Suspension, the Holders agree to suspend use of the applicable Prospectus in connection with any sale or purchase, or offer to sell or purchase, Registrable Securities, upon receipt of the notice referred to above. The Company shall immediately notify the Holders in writing upon the termination of any Demand Suspension, amend or supplement the Prospectus, if necessary, so it does not contain any untrue statement or omission and furnish to the Holders such numbers of copies of the Prospectus as so amended or supplemented as the Holders may reasonably request. The Company shall, if necessary, supplement or amend the Demand Registration, if required by the registration form used by the Company for the Demand Registration or by the instructions applicable to such registration form or by the Securities Act or the rules or regulations promulgated thereunder or as may reasonably be requested by the Holders of a majority of the Registrable Securities that are included in such Demand Registration.

2.1. Right to Piggyback. Whenever the Company proposes to register any of its equity securities under the Securities Act (except (a) with respect to an Initial Public Offering in which neither Advent nor any Advent Holder is participating as a selling stockholder or (b) in connection with a registration on Form S-4 or Form S-8 or any successor or similar form) (a “Piggyback Registration”), the Company will give prompt written notice to the Holders of its intention to effect such a registration and, subject to Sections 2.2 and 2.3 below, will include in such registration all Registrable Securities held by any Holder with respect to which the Company has received written requests for inclusion therein within ten (10) days after the delivery of the Company’s notice. Each such Company notice shall specify the approximate number of Company equity securities to be registered.

2.2. Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company and the managing underwriter(s) advises the Company in writing (with a copy to each applicable party hereto requesting registration of Registrable Securities) that in its opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering in an orderly manner and without adversely affecting the marketability of such offering, the Company will include in such registration: (a) first, the securities the Company proposes to sell, (b) second, the Registrable Securities requested to be included in such registration, pro rata among the respective Holders on the basis of the number of Registrable Securities owned by each such Holder, and (c) third, other

-4-

securities requested to be included in such registration; provided, that, Advent Holdco agrees that if any Other Holder (other than any Advent Holder) has the contractual right to, and elects to, participate in such offering in an amount in excess of such Other Holder’s pro rata portion as determined hereunder, the number of securities of such Other Holder to be included in such offering will reduce the number of securities permitted to be sold by the Advent Holders (collectively, but allocated among them as determined by Advent Holdco or Advent) in such offering; provided, further, that if such underwriter(s) provide written notice advising in good faith that participation in the offering by any Holder who is, or is an Affiliate of, any employee of the Company or any of its Subsidiaries would materially and adversely affect the marketability of such offering, then Registrable Securities held by one or more such Holders may be excluded (in whole or in part) from such offering, even if such exclusion would not allow such Holders to participate on a pro rata basis with such other Holders.

2.3. Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of Company securities (other than the Holders), and the managing underwriter(s) advises the Company in writing that in its opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability of the offering, the Company will include in such registration: (a) first, the securities requested to be included therein by the applicable Holders requesting registration and the Registrable Securities requested to be included in such registration, pro rata among the Holders on the basis of the number of Registrable Securities owned by each such Holder, and (b) second, other such securities requested to be included in such registration; provided, that, Advent Holdco agrees that if any Other Holder (other than any Advent Holder) has the contractual right to, and elects to, participate in such offering in an amount in excess of such Other Holder’s pro rata portion as determined hereunder, the number of securities of such Other Holder to be included in such offering will reduce the number of securities permitted to be sold by the Advent Holders (collectively, but allocated among them as determined by Advent Holdco or Advent) in such offering; provided, further, that if such underwriter(s) provide written notice advising in good faith that participation in the offering by any Holder who is, or is an Affiliate of, any employee of the Company or any of its Subsidiaries would materially and adversely affect the marketability of such offering, then Registrable Securities held by one or more such Holders may be excluded (in whole or in part) from such offering, even if such exclusion would not allow such Holders to participate on a pro rata basis with such other Holders.

3.1. Registration Procedures. Whenever the parties hereto have requested that any Registrable Securities be registered pursuant to this Agreement, the Company will use its best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof and pursuant thereto the Company will as expeditiously as reasonably practicable:

(a) prepare and (within sixty (60) days after the end of the period within which requests for inclusion in such registration may be given to the Company) file with the SEC a Registration Statement with respect to such Registrable Securities and thereafter use its best efforts to cause such Registration Statement to become effective (provided that before filing a Registration

-5-

Statement or Prospectus or any amendments or supplements thereto, the Company will furnish to counsel to the Holders of the Registrable Securities to be included in such registration copies of all such documents proposed to be filed (not to exceed one counsel selected by NIM and one counsel selected by Acceleratio), which documents will be subject to review by such counsel(s));

(b) prepare and file with the SEC such amendments and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary (i) to keep such Registration Statement effective (A) for at least one hundred eighty (180) days (subject to extension pursuant to Section 3.3(b)) or until the Holder or Holders have completed the distribution described in the Registration Statement relating to such distribution, whichever occurs first or, if such Registration Statement relates to an underwritten offering, such longer period as in the opinion of counsel for the underwriters a Prospectus is required by law to be delivered in connection with sales of Registrable Securities by an underwriter or dealer, or (B) in the case of a Shelf Registration, until the earlier of (I) the date on which all Registrable Securities have been sold under the Shelf Registration or otherwise no longer qualify as Registrable Securities, (II) when all such Registrable Securities can be sold without limitation in any ninety (90)-day period under Rule 144, and (III) the latest date allowed by applicable law, and (ii) to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement until such time as all of such securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such Registration Statement;

(c) furnish to each seller of Registrable Securities such number of copies of such Registration Statement, each amendment and supplement thereto, the Prospectus included in such Registration Statement (including each preliminary Prospectus) and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller or as required under applicable securities laws in the relevant jurisdiction;

(d) use its best efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided, that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subsection, (ii) subject itself to taxation in respect of doing business in any such jurisdiction, or (iii) consent to general service of process in any such jurisdiction);

(e) promptly notify each seller of such Registrable Securities, at any time when a Prospectus relating thereto is required to be delivered under the Securities Act, upon discovery that, or upon the discovery of the happening of any event as a result of which, the Prospectus included in such Registration Statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading in the light of the circumstances under which they were made, and, at the request of any such seller, the Company will prepare and furnish to such seller a reasonable number of copies of a supplement or amendment to such Prospectus so that, as thereafter delivered to the prospective purchasers of such Registrable Securities, such Prospectus will not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading in the light of the circumstances under which they were made;

-6-

(f) cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed;

(g) provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such Registration Statement;

(h) enter into such customary agreements (including underwriting agreements in customary form) and perform the Company’s obligations thereunder and take all such other actions as the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities (which might include effecting a stock split or a combination of shares);

(i) make available for inspection by any seller of Registrable Securities, any underwriter participating in any disposition pursuant to such Registration Statement 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, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such Registration Statement, and to cooperate and participate as reasonably requested by any such seller in road show presentations, in the preparation of the Registration Statement, each amendment and supplement thereto, the Prospectus included therein, and other activities as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller; provided, however, that any Person granted access to information regarding the Company pursuant to this Section 3.1(i) shall agree to hold in strict confidence and shall not make any disclosure or use any information regarding the Company that the Company determines in good faith to be confidential, and of which determination such Person is notified, unless (i) the release of such information is requested or required by a governmental, regulatory or self-regulatory authority or is otherwise required by law (including in connection with the sale of Registrable Securities), (ii) such information is or becomes publicly known other than through a breach of this Agreement by such Person (or any other agreement to which such Person has knowledge), (iii) such information is or becomes available to such Person on a non-confidential basis from a source other than the Company or (iv) such information is independently developed by such Person;

(j) otherwise use its best efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, but not later than eighteen (18) months after the effective date of the Registration Statement, an earnings statement covering the period of at least twelve (12) months beginning with the first (1^st) day of the Company’s first full calendar quarter after the effective date of the Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

-7-

(k) in the event of the issuance of any stop order suspending the effectiveness of a Registration Statement, or of any order suspending or preventing the use of any related Prospectus or suspending the qualification of any securities included in such Registration Statement for sale in any jurisdiction, the Company will use its best efforts promptly to obtain the withdrawal of such order;

(l) obtain one or more comfort letters, dated the date of the Prospectus or Prospectus supplement for such offering (and, if such registration includes an underwritten Public Offering, dated the date of the closing under the underwriting agreement), signed by the Company’s independent public accountants in the then-current customary form and covering such matters of the type customarily covered from time to time by comfort letters;

(m) provide a legal opinion of the Company’s outside counsel, dated the date of the closing of the offering (and, if such registration includes an underwritten Public Offering, dated the date of the closing under the underwriting agreement and addressed to the underwriters), with respect to the Registration Statement, each amendment and supplement thereto, the Prospectus included therein (including the preliminary Prospectus) and such other documents relating thereto in the then-current customary form and covering such matters of the type customarily covered from time to time by legal opinions of such nature;

(n) cooperate with the sellers of Registrable Securities covered by the Registration Statement and the managing underwriter(s), if any, to facilitate the timely preparation and delivery, if applicable, of certificates (not bearing any restrictive legends) representing securities to be sold under the Registration Statement, and enable such securities to be in such denominations and registered in such names as the managing underwriter(s), if any, or such holders may request;

-8-

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

3.3. Participation in Underwritten Offerings.

(a) No Person may participate in any registration hereunder that is underwritten unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements (including, without limitation, pursuant to the terms of any over-allotment or “green shoe” option requested by the managing underwriter(s), provided, that no Holder will be required to sell more than the number of Registrable Securities that such Holder has requested the Company to include in any registration) and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, and other documents reasonably required under the terms of such underwriting arrangements.

(b) Each Person that is participating in any registration hereunder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3.1(e) above, such Person will forthwith discontinue the disposition of its Registrable Securities pursuant to the Registration Statement until such Person’s receipt of the copies of a supplemented or amended Prospectus as contemplated by such Section 3.1(e). In the event the Company shall give any such notice, the applicable time period mentioned in Section 3.1(b) during which a Registration Statement is to remain effective shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to this paragraph to and including the date when each seller of a Registrable Security covered by such Registration Statement shall have received the copies of the supplemented or amended Prospectus contemplated by Section 3.1(e).

3.4. Company Holdback. The Company shall not effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during (a) with respect to the Initial Public Offering, the one hundred eighty (180)-day period beginning on the effective date of such Initial Public Offering (except for the exercise of any over-allotment or “green shoe” option requested by the managing underwriter(s)), (b) with respect to any other underwritten Demand Registration or any underwritten Piggyback Registration in which Registrable Securities are included, the seven (7) days prior to and the ninety (90)-day period beginning on the effective date of such registration (or such shorter period as may be agreed to by the managing underwriter(s)), and (c) upon notice from a Holder that it intends to effect an underwritten distribution of Registrable Securities pursuant to a shelf registration (upon receipt of which, the Company will promptly notify all other Holders of the date of the commencement of such distribution), the seven (7) days prior to and the ninety (90)-day period beginning on the date of the Prospectus or Prospectus supplement for such offering (or such shorter period as may be agreed to by the managing underwriter(s)), in each case except as part of such underwritten registration or pursuant to registrations on Form S-4 or Form S-8, and in each case unless the managing underwriter(s) otherwise agrees. In addition, if during the last seventeen (17) days of the applicable restricted period described above, the Company issues an earnings release or material news or a material event relating to the Company occurs, or if, before the applicable restricted period expires, the Company announces that the Company will release earnings results during the sixteen (16)-day time period beginning on such restricted period’s last day, unless otherwise waived by the managing underwriter(s), then the foregoing restrictions will continue to apply until the expiration of the eighteen (18)-day time period beginning on the earnings release issuance or on the occurrence of the material news or material event.

3.5. Current Public Information. At all times after the Company has filed a Registration Statement with the SEC that has been declared effective, the Company will use its reasonable best efforts to timely file all reports and other documents required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder (or, if the Company is not required to file such reports, it will make publicly available such necessary information to permit sales pursuant to Rule 144 under the Securities Act), and will take such further action as any holder or holders of Registrable Securities may reasonably request, all to the extent required to enable such holders to sell Registrable Securities pursuant to Rule 144.

-10-

3.6. Shelf Registration.

(a) Shelf Registration. As promptly as practicable following the consummation of an Initial Public Offering, and in any event no later than twelve (12) months after such consummation, the Company shall file with the SEC a shelf Registration Statement pursuant to Rule 415 under the Securities Act (“Shelf Registration Statement”) relating to the offer and sale of Registrable Securities by the then Holders thereof in accordance with the methods of distribution elected by such Holders, and the Company shall use its reasonable best efforts to cause such Shelf Registration Statement to be declared effective under the Securities Act as soon as practicable after the filing thereof.

(b) Continued Effectiveness. The Company shall use its reasonable best efforts to keep such Shelf Registration Statement continuously effective under the Securities Act in order to permit the Prospectus forming part of the Shelf Registration Statement to be usable by Holders until the earlier of: (i) the date as of which all Registrable Securities have been sold pursuant to the Shelf Registration Statement or another Registration Statement filed under the Securities Act (but in no event prior to the applicable period referred to in Section 4(a)(3) of the Securities Act and Rule 174 thereunder); and (ii) the date as of which no Holder holds Registrable Securities (such period of effectiveness, the “Shelf Period”). Subject to Section 3.6(c), the Company shall be deemed not to have used its reasonable best efforts to keep the Shelf Registration Statement effective during the Shelf Period if the Company voluntarily takes any action or omits to take any action that would result in Holders of the Registrable Securities covered thereby not being able to offer and sell any Registrable Securities pursuant to such Shelf Registration Statement during the Shelf Period, unless such action or omission is required by applicable law.

(c) Suspension of Registration. If the continued use of such Shelf Registration Statement at any time would require the Company to make an Adverse Disclosure, the Company may, upon giving prompt written notice of such action to the Holders, suspend use of the Shelf Registration Statement (a “Shelf Suspension”); provided, however, that the Company shall not be permitted to exercise a Shelf Suspension more than one time during any twelve (12)-month period for a period not to exceed sixty (60) days. In the case of a Shelf Suspension, the Holders agree to suspend use of the applicable Prospectus in connection with any sale or purchase of, or offer to sell or purchase, Registrable Securities, upon receipt of the notice referred to above. The Company shall immediately notify the Holders in writing upon the termination of any Shelf Suspension, amend or supplement the Prospectus, if necessary, so it does not contain any untrue statement or omission and furnish to the Holders such numbers of copies of the Prospectus as so amended or supplemented as the Holders may reasonably request. The Company shall, if necessary, supplement or amend the Shelf Registration Statement, if required by the registration form used by the Company for the Shelf Registration Statement or by the instructions applicable to such registration form or by the Securities Act or the rules or regulations promulgated thereunder or as may reasonably be requested by the Holders of a majority of Registrable Securities that are included in such Shelf Registration Statement.

-11-

(d) Shelf Takedown.

-12-

(e) Priority of Securities Sold Pursuant to Shelf Takedowns. If the managing underwriter or underwriters of a proposed Underwritten Shelf Takedown pursuant to Section 3.6(d) advise the Company in writing that, in its or their opinion, the number of securities requested to be included in the proposed Underwritten Shelf Takedown exceeds the number that can be sold in such Underwritten Shelf Takedown without being likely to have an adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, the number of Registrable Securities to be included in such offering shall be (x) first, allocated to each Holder that has requested to participate in such Underwritten Shelf Takedown an amount equal to the

3.9. No Inconsistent Agreements; Additional Rights. The Company hereby represents and warrants that, as of the date hereof, no registration or similar rights have been granted to any other Person other than pursuant to this Agreement and the Other Registration Rights Agreement. Neither the Company nor any of its Subsidiaries shall enter into any agreement after the date hereof granting registration or similar rights to any holder or prospective holder of any securities of the Company which would allow such holder or prospective holder to include such securities in any registration filed by the Company unless, under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of such securities will not reduce the amount of the Registrable Securities of the Holders party to this Agreement which is included.

4.1. Indemnification by the Company. The Company agrees to indemnify and hold harmless, to the fullest extent permitted by law, each Holder party hereto and, as applicable, (i) its officers, directors, trustees, employees, stockholders, holders of beneficial interests, members, and general and limited partners and (ii) each of their respective Affiliates, officers, directors, trustees, employees, advisors, and agents and each Person who controls (within the meaning of the Securities Act or the Exchange Act) such persons (collectively, such Holder’s “Indemnitees”) against any and all losses, claims, damages, liabilities, joint or several, to which such Holder or any such Indemnitee may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages, or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) (“Losses”) arise out of or are based upon (a) 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, together with any documents incorporated therein by reference or (b) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and the Company will reimburse such Holder and each of its Indemnitees for any legal or any other expenses, including any amounts paid in any settlement effected with the consent of the Company, which consent will not be unreasonably withheld or delayed, incurred by them in connection with investigating or defending any such Losses; provided, that the Company shall not be liable in any such case to the extent that any such Losses arise out of or are based upon an untrue statement or alleged untrue statement, or omission or alleged omission, made in such Registration Statement, any such Prospectus, or preliminary Prospectus or any amendment or supplement thereto, or in any application, in reliance upon, and in conformity with, written information prepared and furnished to the Company by such Holder expressly for use therein. In connection with an underwritten offering, the Company will indemnify such underwriters, their officers, and directors and each Person who controls such underwriters (within the meaning of the Securities Act) in customary form pursuant to the underwriting agreement entered into with such underwriters. It is the intent that with respect to all advancement and indemnification obligations under this Section 4.1, the Company shall be the

-15-

primary source of advancement, reimbursement, and indemnification relative to any direct or indirect shareholder of the Company (or any Affiliate of such shareholder, other than the Company or any of its Subsidiaries), irrespective of any right of recovery the Indemnitee may have from any corporation, limited liability company, partnership, joint venture, trust, employee benefit plan, or other enterprise from whom an Indemnitee may be entitled to indemnification with respect to which, in whole or in part, the Company or any of its Subsidiaries may also have an indemnification obligation, or insurance coverage the Indemnitee may have from any insurer providing insurance coverage to any source (other than the Company or any of its Subsidiaries or the insurer under and pursuant to an insurance policy of the Company or any of its Subsidiaries). The Company shall have no right to seek contribution, indemnity, or other reimbursement for any of its obligations under this Section 4.1 from any such direct or indirect shareholder of the Company (or any Affiliate of such shareholder, other than the Company or any of its Subsidiaries).

4.2. Indemnification by Holders. In connection with any Registration Statement in which a Holder party hereto is participating, each such Holder will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, will (severally and not jointly) indemnify and hold harmless the Company and its Indemnitees, to the fullest extent permitted by the law, against any Losses arising out of or based upon (a) 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 in any application, together with any documents incorporated therein by reference or (b) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, but only to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such Registration Statement, any such Prospectus or preliminary Prospectus or any amendment or supplement thereto, or in any application, in reliance upon and in conformity with written information prepared and furnished to the Company by such Holder expressly for use therein, and such Holder will reimburse the Company and each such Indemnitee for any reasonable and documented out-of-pocket legal or any other expenses, including any amounts paid in any settlement effected with the consent of such Holder, which consent will not be unreasonably withheld or delayed, reasonably incurred by them in connection with investigating or defending any such Losses; provided, however, that the obligation to indemnify will be several, but not joint, and will be limited to the net amount of proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement (after giving effect to any underwriters’ discounts and commissions), less any other amounts paid by such Holder in respect of such untrue statement, alleged untrue statement, omission or alleged omission.

4.3. Procedure. Any Person entitled to indemnification hereunder (the “Indemnified Party”) will (a) give prompt written notice to the indemnifying party (the “Indemnifying Party”) of any claim with respect to which it seeks indemnification (provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent that the Indemnifying Party is actually and materially prejudiced by such failure to give such notice), and (b) unless, in such Indemnified Party’s reasonable judgment, a conflict of interest between such Indemnified Party and Indemnifying Party may exist with respect to such claim, permit such Indemnifying Party to assume the defense of such claim with counsel reasonably satisfactory to the Indemnified Party. If such defense is assumed, the

-16-

Indemnifying Party will not be subject to any liability for any settlement made by the Indemnified Party without its consent (but such consent will not be unreasonably withheld). An Indemnifying Party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such Indemnifying Party with respect to such claim, unless, in the reasonable judgment of any Indemnified Party, a conflict of interest may exist between such Indemnified Party and any other Indemnified Party with respect to such claim.

4.4. Entry of Judgment; Settlement. The Indemnifying Party shall not, except with the approval 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 each Indemnified Party of a release from all liability in respect to such claim or litigation without any payment or consideration provided by such Indemnified Party.

4.5. Contribution. If the indemnification provided for in this Section 4 is, other than expressly pursuant to its terms unavailable to or is insufficient to hold harmless an Indemnified Party under the provisions above in respect of any Losses, then each Indemnifying Party shall, in lieu of indemnifying such Indemnified Party hereunder, contribute to the amount paid or payable by such Indemnified Party as a result of such Losses (a) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the sellers of Registrable Securities and any other sellers participating in the Registration Statement on the other hand from the sale of Registrable Securities pursuant to the registered offering of securities as to which indemnity is sought or (b) only if the allocation provided by clause (a) above is not permitted by applicable law, in such proportion as is appropriate to reflect the relative benefits referred to in clause (a) above but also the relative fault of the Indemnifying Party on the one hand and of the Indemnified Parties on the other hand in connection with the statement or omissions (or alleged statements or omissions) which resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement or omission or alleged omission to state a material fact relates to information supplied by the Company or by the sellers of Registrable Securities or other sellers participating in the Registration Statement and the Parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.

The Company and the sellers of Registrable Securities agree that it would not be just and equitable if contribution pursuant to this Section 4 were determined by pro rata allocation (even if the sellers of Registrable Securities were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the Losses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4, no seller of Registrable Securities shall be required to contribute any amount in excess of the net proceeds (after giving effect to any underwriters discounts and commissions) received by such seller from the sale of Registrable Securities covered by the Registration Statement filed pursuant hereto, less any other amounts paid by such Holder in respect of such untrue statement, alleged untrue statement, omission, or alleged omission. 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 guilty of such fraudulent misrepresentation.

-17-

4.6. Other Rights. The indemnification and contribution by any such party provided for under this Agreement shall be in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract and will remain in full force and effect regardless of any investigation made or omitted by or on behalf of the indemnified party or any officer, director, or controlling Person of such indemnified party and will survive the transfer of securities.

This Agreement and all claims arising out of or based upon this Agreement or relating to the subject matter hereof shall be governed by and construed in accordance with the laws of the State of Delaware without giving effect to any choice or conflict of laws provision or rule that would cause the application of the laws of any other jurisdiction.

6.13. Consent to Jurisdiction. Each party hereto (a) hereby irrevocably submits to the exclusive jurisdiction of the Court of Chancery of the State of Delaware located in Wilmington, Delaware for the purpose of any action, claim, cause of action or suit (in contract, tort or otherwise), inquiry, proceeding or investigation arising out of or based upon this Agreement or relating to the subject matter hereof, (b) hereby waives to the extent not prohibited by applicable law, and agrees not to assert, and agrees not to allow any of its Subsidiaries to assert, by way of motion, as a defense or otherwise, in any such action, any claim that it is not subject personally to the jurisdiction of the above-named court, that its property is exempt or immune from attachment or execution, that any such proceeding brought in the above named court is improper, or that this Agreement or the subject matter hereof or thereof may not be enforced in or by such court, and (c) hereby agrees not to commence or maintain any action, claim, cause of action or suit (in contract, tort or otherwise), inquiry, proceeding or investigation arising out of or based upon this Agreement or relating to the subject matter hereof or thereof other than before the above-named court nor to make any motion or take any other action seeking or intending to cause the transfer or removal of any such action, claim, cause of action or suit (in contract, tort or otherwise), inquiry, proceeding or investigation to any court other than the above-named court whether on the grounds of inconvenient forum or otherwise. Notwithstanding the foregoing, to the extent that any party is or becomes a party in any litigation in connection with which it may assert indemnification rights set forth in this Agreement, the court in which such litigation is being heard shall be deemed to be included in clause (a) above. Notwithstanding the foregoing, any party hereto may commence and maintain an action to enforce a judgment of the above-named court in any court of competent jurisdiction. Each party hereto hereby consents to service of process in any such proceeding in any manner permitted by Delaware law, and agrees that service of process by registered or certified mail, return receipt requested, at its address specified pursuant to Section 6.10 hereof is reasonably calculated to give actual notice.

6.14. WAIVER OF JURY TRIAL. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH PARTY HERETO HEREBY WAIVES AND COVENANTS THAT HE, SHE OR IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE) ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ISSUE OR ACTION, CLAIM, CAUSE OF ACTION OR SUIT (IN CONTRACT, TORT OR OTHERWISE), INQUIRY, PROCEEDING OR INVESTIGATION ARISING OUT OF OR BASED UPON THIS AGREEMENT OR THE SUBJECT MATTER HEREOF OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE TRANSACTIONS CONTEMPLATED HEREBY, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING. EACH PARTY HERETO ACKNOWLEDGES THAT IT HAS BEEN INFORMED BY THE OTHER PARTIES HERETO THAT THIS SECTION 6.14 CONSTITUTES A MATERIAL INDUCEMENT UPON WHICH THEY ARE RELYING AND WILL RELY IN ENTERING INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY HERETO FURTHER AGREES TO IRREVOCABLY WAIVE HIS, HER OR ITS RIGHT TO A TRIAL BY JURY IN ANY PROCEEDING AND ANY SUCH PROCEEDING SHALL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

6.15. Exercise of Rights and Remedies. No delay of or omission in the exercise of any right, power or remedy accruing to any party hereto as a result of any breach or default by any other party hereto shall impair any such right, power or remedy, nor shall it be construed as a waiver of or acquiescence in any such breach or default, or of any similar breach or default occurring later; nor shall any such delay, omission nor waiver of any single breach or default be deemed a waiver of any other breach or default occurring before or after that waiver.

6.16. Aggregation of Registrable Securities. All Registrable Securities held by a Holder party hereto, its Affiliates, and other Person(s) included within the definition of such Holder party hereto shall be aggregated together for purposes of determining the availability of any rights or incurrence of any obligations under this Agreement. The Holders party hereto may allocate to any Person included within the definition of such Holder the ability to exercise any rights and/or the incurrence of any obligations under this Agreement in any manner that such Holder sees fit, provided, that, to the extent applicable, no Person included within the definition of such Holder may exercise any right granted hereunder without the approval of such Person(s) holding at least a majority of the Registrable Securities deemed to be held by such Holder as of the date on which such action is to be taken or such right is to be exercised. For the avoidance of doubt, the control by any Person of any Registrable Security deemed to be held by a Holder party hereto confers no right hereunder other than those granted to such Holder.

6.17. No Recourse. Notwithstanding anything that may be expressed or implied in this Agreement, the Company and each party hereto covenant, agree and acknowledge that no recourse under this Agreement or any documents or instruments delivered in connection with this Agreement shall be had against any current or future director, officer, employee, general or limited partner or member of any party hereto or of any Affiliate or assignee thereof, as such, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any current or future officer, agent or employee of any party hereto or any current or future member of any party hereto or any current or future director, officer, employee, partner or member of any party hereto or of any Affiliate or assignee thereof, as such, for any obligation of any party hereto under this Agreement or any documents or instruments delivered in connection with this Agreement for any claim based on, in respect of or by reason of such obligations or their creation.

6.18. Authority; Effect. Each party hereto represents and warrants to and agrees with each other party hereto that (a) the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized on behalf of such party and do not violate any agreement or other instrument applicable to such party or by which its assets are bound and (b) this Agreement constitutes a legal, valid and binding obligation of such party, enforceable against such party in accordance with its terms, except to the extent that the enforcement of the rights and remedies created hereby is subject to (i) bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting the rights and remedies of creditors generally and (ii) general principles of equity. This Agreement does not, and shall not be construed to, give rise to the creation of a partnership among any of the Parties, or to constitute a joint venture or other association among the Parties.
