3.1 Demand Registration.

(a) Request for Demand Registration.

(i) At any time and from time to time beginning 180 days after the effective date of the IPO, subject to Section 3.4, any Holder shall have the right, for itself or together with one or more other Holders, to make a written request from time to time (a “Demand Registration Request”) to the Company for Registration of all or part of the Registrable Securities held by such Holder (a “Demand Registration”).

(ii) Each Demand Registration Request shall specify (x) the aggregate amount of Registrable Securities proposed to be registered, (y) the intended method or methods of disposition thereof and (z) whether the Demand Registration Request is for an Underwritten Offering or a Shelf Registration (a “Shelf Registration Request”).

(iii) If a Demand Registration Request is for a Shelf Registration, and the Company is eligible to file a Registration Statement on Form S-3, the Company shall promptly file (and in any event within 45 days after the date of such Demand Registration Request) with the SEC a Shelf Registration Statement on Form S-3 pursuant to Rule 415 under the Securities Act relating to the offer and sale of Registrable Securities by the initiating Holders from time to time in accordance with the methods of distribution elected by such Holders, subject to all applicable provisions of this Agreement.

(iv) If the Demand Registration Request is for a Shelf Registration and the Company is not eligible to file a Registration Statement on Form S-3, the Company shall promptly file (and in any event within 60 days after the date of such Demand Registration Request) with the SEC a Shelf Registration Statement on Form S-1 or any other form that the Company is then permitted to use pursuant to Rule 415 under the Securities Act (or such other Registration Statement as the Board of Directors may determine to be appropriate) relating to the offer and sale of Registrable Securities by the initiating Holders from time to time in accordance with the methods of distribution elected by such Holders.

(v) If on the date of the Shelf Registration Request the Company is a WKSI, then any Shelf Registration Statement may (if the Board of Directors determines it to be appropriate to do so) include an unspecified amount of Registrable Securities to be sold by unspecified Holders; if on the date of the Shelf Registration Request the Company is not a WKSI, then the Shelf Registration Request shall specify the aggregate amount of Registrable Securities to be registered.

(b) Limitation on Registrations. The Company shall not be obligated to take any action to effect any Demand Registration if:

(i) a Demand Registration or Piggyback Registration was declared effective or an Underwritten Offering was consummated by either the Company or the Holders within the preceding 90 days;

(ii) the Company has filed another Registration Statement (other than on Form S-8 or Form S-4 or any successor thereto) that has not yet become effective;

(iii) the value of the Registrable Securities proposed to be sold by the initiating Holders is not reasonably expected (in the good faith judgment of the Board of Directors) to yield net proceeds of at least $25 million, in the case of a Shelf Registration on Form S-1, or in the case of an Underwritten Offering, of at least $50 million; or

(iv) if such registration covers Registrable Securities that are issuable upon Exchange under and pursuant to the terms of the A&R LLCA, if the A&R LLCA would not, on the date of the written request for registration, then permit such Exchange, except with the approval of the Board of Directors;

provided that, for the purposes of clauses (i) and (ii), any Registration Statement withdrawn pursuant to Section 3.1(d) shall not affect the Company’s obligation to effect any Demand Registration.

(c) Demand Notice. Promptly upon receipt of a Demand Registration Request pursuant to Section 3.1(a) (but in no event more than 10 Business Days thereafter), the Company shall deliver a written notice of the Demand Registration Request to all other Holders offering each such Holder the opportunity to include in the Demand Registration that number of Registrable Securities as the Holder may request in writing (the “Demand Notice”). Subject to Sections 3.1(g) and 3.1(h), the Company shall include in the Demand Registration all such Registrable Securities with respect to which the Company has received written requests for inclusion therein within ten Business Days after the date that the Demand Notice was delivered.

(d) Demand Withdrawal. Each Holder that has requested the inclusion of Registrable Securities in a Registration (other than a Registration in connection with a Public Offering) pursuant to Sections 3.1(a) or 3.1(c) may withdraw all or any portion of its Registrable Securities from that registration at any time prior to the effectiveness of the applicable Registration Statement by delivering written notice to the Company. Upon receipt of a notice or notices withdrawing (i) all of the Registrable Securities included in that Registration Statement by the initiating Holder(s) or (ii) a number of such Registrable Securities so as to cause the expected net proceeds to fall below the applicable threshold set forth in Section 3.1(b), the Company shall cease all efforts to secure effectiveness of the applicable Registration Statement.

(e) Effectiveness.

(i) The Company shall use commercially reasonable efforts to cause any Registration Statement filed by it pursuant to this Agreement to become effective as promptly as practicable, subject to all applicable provisions of this Agreement.

(ii) The Company shall use commercially reasonable efforts to keep any Shelf Registration Statement filed on Form S-3 continuously effective under the Securities Act to permit the Prospectus forming a part of it to be usable by Holders until the earlier of: (A) the date as of which all Registrable Securities have been sold pursuant to that 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); (B) the date as of which no Holder whose Registrable Securities are registered on such Form S-3 holds Registrable Securities; (C) any date reasonably determined by the Board of Directors to be appropriate, excluding any date that is fewer than 180 days after the effectiveness of the Registration Statement; and (D) the third anniversary of the effectiveness of the Registration Statement.

(iii) If the Registration Statement filed is a Shelf Registration Statement on any form other than Form S-3 and such Registration Statement was not filed in connection with an Underwritten Offering, the Company shall use commercially reasonable efforts to keep the Registration Statement continuously effective under the Securities Act until such time as the Company is eligible to file a Shelf Registration Statement on Form S-3 covering the Registrable Securities thereon or such shorter period during which all Registrable Securities included in the Registration Statement have actually been sold.

(iv) If the Registration Statement filed is a Shelf Registration Statement on any form other than Form S-3 and such Registration Statement was filed in connection with an Underwritten Offering, the Company shall use commercially reasonable efforts to keep the Registration Statement continuously effective under the Securities Act, for a period of at least 180 days after the effective date thereof or such longer period as the underwriters for any Underwritten Offering may determine to be appropriate, or such shorter period during which all Registrable Securities included in the Registration Statement have actually been sold; provided that such period shall be extended for a period of time equal to the period the Holders of Registrable Securities may be required to refrain from selling any securities included in the Registration Statement at either the request of the Company or an underwriter of the Company pursuant to the provisions of this Agreement.

(f) Delay in Filing; Suspension of Registration. If the filing, initial effectiveness or continued use of a 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, delay the filing or initial effectiveness of, or suspend use of, the Registration Statement (a “Suspension”); provided, however, that a Suspension shall not exceed (i) a period of 60 days on any one occasion or (ii) an aggregate of 90 days in any 12-month period. In the case of a 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 Suspension. The Company shall, if necessary, amend or supplement the Prospectus 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 Registration Statement, if required by the registration form used by the Company for the 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 Registration Statement. The Company shall not register any securities for its own account or that of any other member or stockholder (as applicable) during any Suspension, other than an Excluded Registration.

(g) Priority of Securities in Underwritten Offerings. If the managing underwriter or underwriters of any proposed Underwritten Offering advise the Company in writing that, in its or their opinion, the number of securities requested to be included in the proposed offering exceeds the number that can be sold in that offering 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 shall be (i) first, allocated to each Holder that has requested to participate in such Underwritten Offering an amount equal to the lesser of (x) the number of such Registrable Securities requested to be registered or sold by such Holder, and (y) a number of such shares equal to such Holder’s Pro Rata Portion, and (ii) second, and only if all securities referred to in clause (i) have been included, the number of other securities that, in the opinion of such managing underwriter or underwriters, can be sold without having such adverse effect.

(h) Participation in Underwritten Offerings. No Person may participate in any Underwritten Offering hereunder unless that ▇▇▇▇▇▇ agrees to sell the Registrable Securities it desires to have covered by the applicable Registration Statement on the basis provided in any underwriting arrangements in customary form and completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, and other documents required under the terms of the underwriting arrangements; provided that no Person shall be required to make representations and warranties other than those related to title and ownership of their shares and as to the accuracy and completeness of statements made in a Registration Statement, prospectus, offering circular, or other document in reliance upon and conformity with written information furnished to the Company or the managing underwriter by such Person.

(i) Resale Rights. In the event that a Holder that is a partnership, limited liability company, trust or similar entity requests to participate in a Registration pursuant to this Section 3.1 in connection with a distribution of Registrable Securities to its partners, members or beneficiaries, the Registration shall provide for resale by such partners, members or beneficiaries.

3.2 Shelf Takedowns.

(a) At any time the Company has an effective Shelf Registration Statement with respect to Registrable Securities, a Holder, by notice to the Company specifying the intended method or methods of disposition thereof, may make a written request (a “Shelf Takedown Request”) that the Company effect an Underwritten Shelf Takedown of all or a portion of such Holder’s Registrable Securities that are registered on such Shelf Registration Statement, and as soon as practicable thereafter, the Company shall amend or supplement the Shelf Registration Statement as necessary for such purpose, subject to all applicable provisions of this Agreement.

(b) Promptly upon receipt of a Shelf Takedown Request (but in no event more than two Business Days thereafter (or such shorter period as may be reasonably requested in connection with an underwritten “block trade”)) for any Underwritten Shelf Takedown, the Company shall deliver a notice (a “Shelf Takedown Notice”) to each other Holder with Registrable Securities covered by the applicable Registration Statement, or to all other Holders if such Registration Statement is undesignated (each a “Potential Takedown Participant”). The Shelf Takedown Notice shall offer each such Potential Takedown Participant the opportunity to include in any Underwritten Shelf Takedown such number of Registrable Securities as each such Potential Takedown Participant may request in writing. The Company shall include in the Underwritten Shelf Takedown all such Registrable Securities with respect to which the Company has received written requests for inclusion therein within three Business Days (or such shorter period as may be reasonably requested in connection with an underwritten “block trade”) after the date that the Shelf Takedown Notice has been delivered. Notwithstanding the delivery of any Shelf Takedown Notice, all determinations as to whether to complete any Underwritten Shelf Takedown and as to the timing, manner, price and other terms of any Underwritten Shelf Takedown contemplated by this Section 3.2 shall be determined by the initiating Holders.

3.3 Piggyback Registration.

(a) Participation. If the Company at any time proposes to file a Registration Statement under the Securities Act or to conduct a Public Offering with respect to any offering of its equity securities for its own account or for the account of any other Persons (other than (i) a Registration under Sections 3.1 or 3.2, (ii) a Registration on Form S-4 or Form S-8 or any successor form to such forms, (iii) a Registration of securities solely relating to an offering and sale to employees or directors of the Company or its subsidiaries pursuant to any employee stock plan, employee stock purchase plan, or other employee benefit plan arrangement, (iv) a Registration solely for the registration of securities issuable upon the conversion, exchange or exercise of any then-outstanding security of the Company or (v) a Registration relating to a dividend reinvestment plan), then as soon as practicable (but in no event less than 10 Business Days prior to the proposed date of filing of such Registration Statement or, in the case of a Public Offering under a Shelf Registration Statement, the anticipated pricing or trade date), the Company shall give written notice (a “Piggyback Notice”) of such proposed filing or Public Offering to all Holders, and such Piggyback Notice shall offer the Holders the opportunity to register under such Registration Statement, or to sell in such Public Offering, such number of Registrable Securities as each such Holder may request in writing (a “Piggyback Registration”). The Company shall not be required to provide a Piggyback Notice to Holders of any Registrable Securities that are already registered pursuant to an effective Registration Statement unless the Company is proposing to conduct a Public Offering that is an Underwritten Offering. Subject to Section 3.1(b), the Company shall include in such Registration Statement or in such Public Offering as applicable, all such Registrable Securities that are requested to be included therein within ten Business Days (the “Piggyback Notice Period”) after the receipt by such Holder of

any such notice; provided, however, that if the length of the notice period under the A&R LLCA for converting Class B Units in connection with a “Block Trade” as defined in the A&R LLCA is not at least five days longer than the Piggyback Notice Period, or if an exchange of Class B Units cannot otherwise be effected such that Registrable Securities cannot be included in such Piggyback Registration, then the Company shall use net proceeds from such Public Offering to repurchase a number of Class A Common Stock and Class B Units underlying Registrable Securities that such Holder had requested to be included in such Piggyback Registration within the Piggyback Notice Period; provided, further, that if at any time after giving written notice of its intention to register or sell any securities and prior to the effective date of the Registration Statement filed in connection with such Registration, or the pricing or trade date of a Public Offering under a Shelf Registration Statement, the Company determines for any reason not to register or sell or to delay Registration or the sale of such securities, the Company shall give written notice of such determination to each Holder and, thereupon, (1) in the case of a determination not to register or sell, shall be relieved of its obligation to register or sell any Registrable Securities in connection with such Registration or Public Offering (but not from its obligation to pay the Registration Expenses in connection therewith), without prejudice, however, to the rights of any Holders entitled to request that such Registration or sale be effected as a Demand Registration under Section 3.1 or an Underwritten Shelf Takedown, as the case may be, and (2) in the case of a determination to delay Registration or sale, in the absence of a request for a Demand Registration or an Underwritten Shelf Takedown, as the case may be, shall also be permitted to delay registering or selling any Registrable Securities. Any Holder shall have the right to withdraw all or part of its request for inclusion of its Registrable Securities in a Piggyback Registration by giving written notice to the Company of its request to withdraw prior to such Registration the securities being registered in such Piggyback Registration. In addition, in the IPO and any subsequent Underwritten Offering in which some or all net proceeds to the Company from such offering are intended to be used to repurchase Class B Units or Common Stock (the amount of such net proceeds, the “Repurchase Amount”), no persons shall receive any portion of the Repurchase Amount unless any EIP Holder is given the right to receive a Pro Rata Portion of the Repurchase Amount with respect to the repurchase of such EIP Holder’s Class B Units or Registrable Securities. In addition, except as otherwise agreed in writing by the EIP Holders, the EIP Holders shall receive all of the Repurchase Amount in the IPO.

In connection with each Registration or sale of Registrable Securities pursuant to Sections 3.1 or 3.3 conducted as an Underwritten Offering, in each case, in which the Company alone is offering to sell its equity securities or the Holders had the right to participate under the terms of this Agreement, each Holder agrees to execute and deliver a lock-up agreement with the underwriter(s) of such Public Offering restricting such Holder’s right to, (a) Transfer, directly or indirectly, any equity securities of the Company held by such Holder, or (b) enter into any swap or other arrangement that transfers to another any of the economic consequences of ownership of such securities during the period commencing on the date of the final Prospectus relating to such Public Offering and ending on the date specified by the underwriters (such period not to exceed 180 days, in the case of the IPO, and 90 days, in the case of subsequent Public Offerings subject to this section), in each case, excluding transfers pursuant to any carve-outs in the applicable lock-up agreement; provided, however, that each director and executive officer of the Company and each other Holder of Registrable Securities shall have entered into a lock-up agreement on terms no more favorable than those entered into by such Holder. The terms of such lock-up agreements shall be negotiated among the Holders, the Company and the underwriters and shall include customary carve-outs from the restrictions on Transfer set forth therein.

The Company may require each seller of Registrable Securities as to which any Registration or sale is being effected to furnish to the Company such information regarding the distribution of such securities and such other information relating to such Holder and its ownership of Registrable Securities as the Company may from time to time reasonably request in writing and the Company may exclude from such Registration or sale the Registrable Securities of any such Holder who unreasonably fails to furnish such information within a reasonable time after receiving such request.

3.6 Underwritten Offerings.

(a) Shelf and Demand Registrations. If requested by the underwriters for any Underwritten Offering, pursuant to a Registration or sale under Section 3.1, the Company shall enter into an underwriting agreement with such underwriters, such agreement to be reasonably satisfactory in substance and form to each of the Company, the participating Holders and the underwriters, and to contain such representations and warranties by the Company and such other terms as are generally prevailing in agreements of that type, including indemnities no less favorable to the recipient thereof than those provided in Section 3.9. The Holders of the Registrable Securities proposed to be distributed by such underwriters shall cooperate with the Company in the negotiation of the underwriting agreement and shall give consideration to the reasonable suggestions of the Company regarding the form thereof, and such Holders shall

complete and execute all questionnaires, powers of attorney and other documents reasonably requested by the underwriters and required under the terms of such underwriting arrangements. Any such Holder shall not be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Holder, such Holder’s title to the Registrable Securities, such Holder’s intended method of distribution and any other representations to be made by the Holder as are generally prevailing in agreements of that type, and the aggregate amount of the liability of such Holder under such agreement shall not exceed such Holder’s proceeds from the sale of its Registrable Securities in the offering, net of underwriting discounts and commissions but before expenses.

(b) Piggyback Registrations. If the Company proposes to register or sell any of its securities under the Securities Act as contemplated by Section 3.3 and such securities are to be distributed through one or more underwriters, the Company shall, if requested by any Holder pursuant to Section 3.3, and subject to the provisions of Section 3.3(b), arrange for such underwriters to include on the same terms and conditions that apply to the other sellers in such Registration or sale all the Registrable Securities to be offered and sold by such Holder among the securities of the Company to be distributed by such underwriters in such Registration or sale. The Holders of Registrable Securities to be distributed by such underwriters shall be parties to the underwriting agreement between the Company and such underwriters and shall complete and execute all questionnaires, powers of attorney and other documents reasonably requested by the underwriters and required under the terms of such underwriting arrangements. Any such Holder shall not be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Holder, such Holder’s title to the Registrable Securities, such Holder’s intended method of distribution and any other representations to be made by the Holder as are generally prevailing in agreements of that type, and the aggregate amount of the liability of such Holder shall not exceed such Holder’s proceeds from the sale of its Registrable Securities in the offering, net of underwriting discounts and commissions but before expenses.

(c) Selection of Underwriters. In the case of an Underwritten Offering under Sections 3.1 or 3.2, the managing underwriter or underwriters to administer the offering shall be determined by the Holders holding a majority of the Registrable Securities being sold; provided that such underwriter or underwriters shall be reasonably acceptable to the Company.

3.7 No Inconsistent Agreements. Neither the Company nor any of its subsidiaries shall hereafter enter into, and neither the Company nor any of its subsidiaries is currently a party to, any agreement with respect to its securities that is inconsistent with the rights granted to the Holders by this Agreement.

3.8 Registration Expenses. All expenses incident to the Company’s performance of or compliance with this Agreement shall be paid by the Company, including (i) all registration and filing fees, and any other fees and expenses associated with filings required to be made with the SEC or FINRA, (ii) all fees and expenses in connection with compliance with any securities or “Blue Sky” laws (including reasonable fees and disbursements of counsel for the underwriters in connection with Blue Sky qualifications of the Registrable Securities), (iii) all printing, duplicating, word processing, messenger, telephone, facsimile and delivery expenses (including

expenses of printing certificates for the Registrable Securities in a form eligible for deposit with The Depository Trust Company and of printing prospectuses), (iv) all fees and disbursements of counsel for the Company and of all independent certified public accountants or independent auditors of the Company and any subsidiaries of the Company (including the expenses of any special audit and comfort letters required by or incident to such performance), (v) all fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange or quotation of the Registrable Securities on any inter-dealer quotation system, (vi) all fees and expenses of any special experts or other Persons retained by the Company in connection with any Registration or sale, (vii) all of the Company’s internal expenses (including all salaries and expenses of its officers and employees performing legal or accounting duties) (viii) all expenses related to the “road show” for any Underwritten Offering (including the reasonable out-of-pocket expenses of the Holders and underwriters, if so requested) and (ix) the reasonable fees and disbursements, not to exceed US$50,000 per registration, of one counsel for the selling Holders (excluding, for the avoidance of doubt, any counsel retained by or on behalf of the Piggyback Holders). All such expenses are referred to herein as “Registration Expenses.” The Company shall not be required to pay any fees and disbursements to underwriters not customarily paid by the issuers of securities in an offering similar to the applicable offering, including underwriting discounts and commissions and transfer taxes, if any, attributable to the sale of Registrable Securities.

3.9 Indemnification.

(a) Indemnification by the Company. The Company shall indemnify and hold harmless, to the full extent permitted by law, each Holder, each shareholder, member, limited or general partner of such Holder, each shareholder, member, limited or general partner of each such shareholder, member, limited or general partner, each of their respective Affiliates, officers, directors, shareholders, employees, advisors, and agents and each Person who controls (within the meaning of the Securities Act or the Exchange Act) such Persons and each of their respective Representatives from and against any and all losses, penalties, judgments, suits, costs, claims, damages, liabilities and expenses, joint or several (including reasonable costs of investigation and legal expenses) (each, a “Loss” and collectively “Losses”) arising out of or based upon (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Securities are registered or sold under the Securities Act (including any final, preliminary or summary Prospectus contained therein or any amendment thereof or supplement thereto or any documents incorporated by reference therein), (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus or preliminary Prospectus, in light of the circumstances under which they were made) not misleading; provided that no selling Holder shall be entitled to indemnification pursuant to this Section 3.9(a) in respect of any untrue statement or omission contained in any information relating to such selling Holder furnished in writing by such selling Holder to the Company specifically for inclusion in a Registration Statement and used by the Company in conformity therewith (such information, “Selling Stockholder Information”), or (iii) any violation by the Company (as finally determined by a court of competent jurisdiction) of the Securities Act or any other similar federal or state securities laws or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance; provided that the indemnification required by this clause (iii) shall

not apply to any loss or liability to the extent arising from such ▇▇▇▇▇▇’s Selling Stockholder Information. This indemnity shall be in addition to any liability the Company may otherwise have. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Holder or any indemnified party and shall survive the Transfer of such securities by such Holder and regardless of any indemnity agreed to in the underwriting agreement that is less favorable to the Holders. The Company shall also indemnify underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the distribution, their officers and directors and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above (with appropriate modification) with respect to the indemnification of the indemnified parties.

(b) Indemnification by the Selling Holders. Each selling Holder agrees (severally and not jointly) to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers and each Person who controls the Company (within the meaning of the Securities Act or the Exchange Act) from and against any Losses resulting from (i) any untrue statement of a material fact in any Registration Statement under which such Registrable Securities were registered or sold under the Securities Act (including any final, preliminary or summary Prospectus contained therein or any amendment thereof or supplement thereto or any documents incorporated by reference therein) or (ii) any omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus or preliminary Prospectus, in light of the circumstances under which they were made) not misleading, in each case to the extent, but only to the extent, that such untrue statement or omission is contained in such selling Holder’s Selling Stockholder Information. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the proceeds from the sale of its Registrable Securities in the offering giving rise to such indemnification obligation, net of underwriting discounts and commissions but before expenses, less any amounts paid by such Holder pursuant to Section 3.9(d) and any amounts paid by such Holder as a result of liabilities incurred under the underwriting agreement, if any, related to such sale.

(c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that any delay or failure to so notify the indemnifying party shall relieve the indemnifying party of its obligations hereunder only to the extent, if at all, that it is actually and materially prejudiced by reason of such delay or failure) and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any Person entitled to indemnification hereunder shall have the right to select and employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Person unless (w) the indemnifying party has agreed in writing to pay such fees or expenses, (x) the indemnifying party shall have failed to assume the defense of such claim within a reasonable time after receipt of notice of such claim from the Person entitled to indemnification hereunder and employ counsel reasonably satisfactory to such Person, (y) the indemnified party has reasonably concluded (based upon advice of its counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, or (z) in the reasonable judgment of any such Person (based upon advice of its counsel) a conflict of interest may exist between such Person and the

indemnifying party with respect to such claims (in which case, if the Person notifies the indemnifying party in writing that such Person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such Person). If the indemnifying party assumes the defense, then no indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (1) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (2) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party. If such defense is not assumed by the indemnifying party, the indemnifying party shall not be subject to any liability for any settlement made without its prior written consent, but such consent may not be unreasonably withheld. It is understood that the indemnifying party or parties shall not, except as specifically set forth in this Section 3.9(c), in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements or other charges of more than one separate firm admitted to practice in such jurisdiction at any one time unless (A) the employment of more than one counsel has been authorized in writing by the indemnifying party or parties, (B) an indemnified party has reasonably concluded (based on the advice of counsel) that there may be legal defenses available to it that are different from or in addition to those available to the other indemnified parties or (C) a conflict or potential conflict exists or may exist (based upon advice of counsel to an indemnified party) between such indemnified party and the other indemnified parties, in each of which cases the indemnifying party shall be obligated to pay the reasonable fees and expenses of such additional counsel or counsels.

(d) Contribution. If for any reason the indemnification provided for in Sections 3.9(a) and (b) is unavailable to an indemnified party or insufficient in respect of any Losses referred to therein (other than as a result of exceptions or limitations on indemnification contained in Sections 3.9(a) and (b)), then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party or parties on the other hand in connection with the acts, statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. In connection with any Registration Statement filed with the SEC by the Company, the relative fault of the indemnifying party on the one hand and the indemnified party on the other hand shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just or equitable if contribution pursuant to this Section 3.9(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 3.9(d). 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. The amount paid or payable by an indemnified party as a result of the Losses referred to in Sections 3.9(a) and (b) 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 3.9(d), in connection with any Registration Statement filed by the Company, a selling Holder shall not be required to contribute any amount in excess of the dollar amount of the proceeds from the sale of its Registrable Securities in the offering giving rise to such contribution obligation, net of underwriting discounts and commissions but before expenses, less any amounts paid by such Holder pursuant to Section 3.9(b) and any amounts paid by such Holder as a result of liabilities incurred under the underwriting agreement, if any, related to such sale. If indemnification is available under this Section 3.9, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Sections 3.9(a) and (b) hereof without regard to the provisions of this Section 3.9(d). The remedies provided for in this Section 3.9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

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

3.10 Rules 144 and 144A and Regulation S. The Company shall file the reports 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 shall, upon the request of any Holder, make publicly available such necessary information for so long as necessary to permit sales that would otherwise be permitted by this Agreement pursuant to Rule 144, Rule 144A or Regulation S under the Securities Act, as such rules may be amended from time to time or any similar rule or regulation hereafter adopted by the SEC), and it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without Registration under the Securities Act in transactions that would otherwise be permitted by this Agreement and within the limitation of the exemptions provided by (i) Rule 144, Rule 144A or Regulation S under the Securities Act, as such rules may be amended from time to time, or (ii) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements and, if not, the specifics thereof.

3.11 Existing Registration Statements. Notwithstanding anything herein to the contrary and subject to applicable law and regulation, the Company may satisfy any obligation hereunder to file a Registration Statement or to have a Registration Statement become effective by a specified date by designating, by notice to the Holders, a Registration Statement that previously has been filed with the SEC or become effective, as the case may be, as the relevant Registration Statement for purposes of satisfying such obligation, and all references to any such obligation shall be construed accordingly; provided that such previously filed Registration Statement may be, and is, amended or, subject to applicable securities laws, supplemented to add the number of Registrable Securities, and, to the extent necessary, to identify as selling stockholders those Holders demanding the filing of a Registration Statement pursuant to the terms of this

Agreement. To the extent this Agreement refers to the filing or effectiveness of other Registration Statements, by or at a specified time and the Company has, in lieu of then filing such Registration Statements or having such Registration Statements become effective, designated a previously filed or effective Registration Statement as the relevant Registration Statement for such purposes, in accordance with the preceding sentence, such references shall be construed to refer to such designated Registration Statement, as amended or supplemented in the manner contemplated by the immediately preceding sentence.

3.12 ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Policy. From and after the effectiveness of this Agreement, the Company shall maintain an ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ policy that (i) permits directors, officers, employees, and other persons subject to such policy to adopt, amend, and terminate trading plans that comply with Rule 10b5-1 under the Exchange Act and (ii) does not impose conditions or restrictions that would unreasonably impede any such person from adopting such a plan.

If to a Holder, to the address on file in the Company’s records.

Notice to the holder of record of any Registrable Securities shall be deemed to be notice to the Holder of such securities for all purposes hereof.

Unless otherwise specified herein, such notices or other communications shall be deemed effective (i) on the date received, if personally delivered, (ii) on the date received if delivered by facsimile or e-mail on a Business Day, or if not delivered on a Business Day, on the first Business Day thereafter and (iii) two Business Days after being sent by overnight courier. Each of the parties hereto shall be entitled to specify a different address by giving notice as aforesaid to each of the other parties hereto.

4.3 Termination and Effect of Termination. This Agreement shall terminate upon the date on which no Holder holds any Registrable Securities, except for the provisions of Sections 3.9 and 3.10, which shall survive any such termination. No termination under this Agreement shall relieve any Person of liability for breach or Registration Expenses incurred prior to termination. In the event this Agreement is terminated, each Person entitled to indemnification rights pursuant to Section 3.9 hereof shall retain such indemnification rights with respect to any matter that (i) may be an indemnified liability thereunder and (ii) occurred prior to such termination.

4.4 Permitted Transferees. The rights of a Holder hereunder may be assigned (but only with all related obligations as set forth below) in connection with a Transfer of Registrable Securities to a Permitted Transferee of that Holder. Without prejudice to any other or similar conditions imposed hereunder with respect to any such Transfer, no assignment permitted under the terms of this Section 4.4 shall be effective unless the Permitted Transferee to which the assignment is being made, if not a Holder, has delivered to the Company a written acknowledgment and agreement in form and substance reasonably satisfactory to the Company that the Permitted Transferee shall be bound by, and shall be a party to, this Agreement. A Permitted Transferee to whom rights are transferred pursuant to this Section 4.4 may not again transfer those rights to any other Permitted Transferee, other than as provided in this Section 4.4. For the avoidance of doubt, any Permitted Transferee of a Piggyback Holder to whom rights are transferred pursuant to this Section 4.4 shall succeed only to the piggyback registration rights of such Piggyback Holder under Section 3.3, and shall not acquire any rights under Sections 3.1 or 3.2 of this Agreement.

4.5 Remedies. The parties to this Agreement shall have all remedies available at law, in equity or otherwise in the event of any breach or violation of this Agreement or any default hereunder. The parties acknowledge and agree that in the event of any breach of this Agreement, in addition to any other remedies that may be available, each of the parties hereto shall be entitled to specific performance of the obligations of the other parties hereto and, in addition, to such other equitable remedies (including preliminary or temporary relief) as may be appropriate

in the circumstances. No delay of or omission in the exercise of any right, power or remedy accruing to any party as a result of any breach or default by any other party under this Agreement 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.

4.6 Amendments. This Agreement may not be orally amended, modified, extended or terminated, nor shall any oral waiver of any of its terms be effective. This Agreement may be amended, modified, extended or terminated, and the provisions hereof may be waived, only by an agreement in writing signed by the Company and the Holders of a majority of the Registrable Securities held by EIP Holders under this Agreement; provided, however, that any amendment, modification, extension or termination that disproportionately and adversely affects the EIP Holders shall require the prior written consent of the EIP Holders; and provided, further, that any amendment, modification, extension or termination that disproportionately and adversely affects the Piggyback Holders shall require the prior written consent of the Piggyback Holders. Each such amendment, modification, extension or termination shall be binding upon each party hereto. In addition, each party hereto may waive any right hereunder by an instrument in writing signed by such party.

4.7 Governing Law. 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 domestic substantive 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 domestic substantive laws of any other jurisdiction.

4.8 Consent to Jurisdiction. Each party to this Agreement, by its execution hereof, (i) hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the State of Delaware and the County of New Castle 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, (ii) 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 courts, that its property is exempt or immune from attachment or execution, that any such proceeding brought in one of the above-named courts is improper, or that this Agreement or the subject matter hereof or thereof may not be enforced in or by such court and (iii) 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 one of the above-named courts 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 one of the above-named courts whether on the grounds of inconvenient forum or otherwise. Notwithstanding the foregoing, to the extent that any party hereto 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 (i) above. Notwithstanding the foregoing, any party to this Agreement may

commence and maintain an action to enforce a judgment of any of the above-named courts 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 4.2 hereof is reasonably calculated to give actual notice.

4.9 WAIVER OF JURY TRIAL. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH PARTY HERETO HEREBY WAIVES AND COVENANTS THAT IT SHALL 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 4.9 CONSTITUTES A MATERIAL INDUCEMENT UPON WHICH THEY ARE RELYING AND SHALL RELY IN ENTERING INTO THIS AGREEMENT. ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 4.9 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.

4.10 ▇▇▇▇▇▇; Binding Effect, Etc. This Agreement constitutes the entire agreement of the parties with respect to its subject matter, supersedes all prior or contemporaneous oral or written agreements or discussions with respect to such subject matter, and shall be binding upon and inure to the benefit of the parties hereto and thereto and their respective heirs, representatives, successors and permitted assigns. Except as otherwise expressly provided herein, no Holder or other party hereto may assign any of its respective rights or delegate any of its respective obligations under this Agreement without the prior written consent of the other parties hereto, and any attempted assignment or delegation in violation of the foregoing shall be null and void.

4.11 Counterparts. This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic transmission shall be effective as delivery of a manually executed counterpart thereof. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Agreement or any document to be signed in connection with this Agreement shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.

4.12 Severability. In the event that any provision hereof would, under applicable law, be invalid or unenforceable in any respect, such provision shall be construed by modifying or limiting it so as to be valid and enforceable to the maximum extent compatible with, and possible under, applicable law. The provisions hereof are severable, and in the event any provision hereof should be held invalid or unenforceable in any respect, it shall not invalidate, render unenforceable or otherwise affect any other provision hereof.
