A Requesting Stockholder may require any Demand Registration that involves a Public Offering of at least $25,000,000 to be conducted as an underwritten offering.

(b) Promptly after the expiration of the 10 Business Day period referred to in Section 2.01(a)(ii) , the Company will notify all Registering Stockholders of the identities of the other Registering Stockholders and the number of shares of Registrable Securities requested to be included in the Demand Registration.

(c) The Company shall be liable for and pay all Registration Expenses in connection with any Demand Registration, regardless of whether such Demand Registration becomes effective; provided, however, that if the Requesting Stockholder revokes its request in whole pursuant to Section 2.01(b) , the Requesting Stockholder shall reimburse the Company for and/or pay directly one-half (100%, in the case of a Requesting Stockholder other than a KPS Stockholder) of the Registration Expenses incurred relating to such Demand Registration.

(d) A Demand Registration shall not be deemed to have occurred or have been completed for purposes of Section 2.01(a) :

(i) unless the Registration Statement relating thereto (A) has become effective under the Securities Act and (B) has remained continuously effective for a period of at least (x) 180 days (or such shorter period in which all Registrable Securities of the Registering Stockholders included in such registration have actually been sold thereunder) or (y) with respect to a Shelf Registration, until the date set forth in Section 2.04(a) ; provided that such Registration Statement shall not be considered a Demand Registration if, after such Registration Statement becomes effective, (1) such Registration Statement is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court and (2) less than 75% of the Registrable Securities included in such Registration Statement have been sold thereunder; or

(ii) if the Maximum Offering Size is reduced in accordance with Section 2.01(e) such that less than 66 ² / ₃ % of the Registrable Securities of the Requesting Stockholder sought to be included in such registration are included.

(e) If a Demand Registration involves a Public Offering and the lead managing underwriter advises the Company and the Requesting Stockholder that, in its view, the number of shares of Registrable Securities requested to be included in such registration (including any securities that the Company proposes to be included that are not Registrable Securities) exceeds the largest number of shares that can be sold without having a material and adverse effect on such offering, including the price at which such shares can be sold (the “ Maximum Offering Size ”), the Company shall include in such registration, in the priority listed below, up to the Maximum Offering Size:

(i) first, all Registrable Securities requested to be registered by the Requesting Stockholder and all other Registering Stockholders (allocated, if necessary for the offering not to exceed the Maximum Offering Size, to give first priority to the inclusion of the Registrable Securities of the Requesting Stockholder and, thereafter, pro rata among the remaining Registering Stockholders on the basis of the relative number of shares of Registrable Securities so requested to be included in such registration by each such Registering Stockholder);

(ii) second, any securities proposed to be registered by the Company; and

(iii) third, any securities proposed to be registered for the account of any other Persons, with such priorities among them as the Company shall determine.

Upon the occurrence of any of the conditions described in (i), (ii) or (iii) above, the Company shall give prompt notice of such suspension (and whether such action is

9

being taken pursuant to (i), (ii) or (iii) above) (a “ Suspension Notice ”) to the Stockholders. Upon the termination of such condition, the Company shall give prompt notice thereof to the Stockholders and shall promptly proceed with all Registration Actions that were suspended pursuant to this paragraph.

The Company may only suspend Registration Actions pursuant to the preceding paragraph on two occasions during any one-year period for a reasonable time specified in the Suspension Notice but not exceeding an aggregate of 90 days (which period may not be extended or renewed) (each such occasion, a “ Suspension Period ”). Each Suspension Period shall be deemed to begin on the date the relevant Suspension Notice is given to the Stockholders and shall be deemed to end on the earlier to occur of (i) the date on which the Company gives the Stockholders a notice that the Suspension Period has terminated and (ii) the date on which the number of days during which a Suspension Period has been in effect exceeds the 90-day period. If the filing of any Demand Registration is suspended pursuant to this Section 2.01(f) , once the Suspension Period ends the Requesting Stockholder may request a new Demand Registration. Notwithstanding anything to the contrary in this Agreement, the Company shall not be in breach of, or failed to comply with, any obligation under this Agreement where the Company acts or omits to take any action in order to comply with applicable law, any interpretation of the staff of the SEC or any order or decree of any court or governmental agency.

Section 2.02. Shelf and Piggyback Registration . (a) At any time when (i) the Company is eligible for use of Form S-3 in connection with a secondary public offering of its equity securities and (ii) a Shelf Registration on a Form S-3 registering Registrable Securities for resale is not then effective (subject to any applicable Suspension Period), upon the written request of any Stockholder, the Company shall use its commercially reasonable efforts to register, under the Securities Act on Form S-3 for an offering on a delayed or continuous basis pursuant to Rule 415 promulgated under the Securities Act (a “ Shelf Registration ”), the offer and sale of all or a portion of the Registrable Securities owned by such Requesting Stockholder. Upon the receipt of such written request, the Company shall promptly give notice (via facsimile or electronic transmission) of such requested Shelf Registration at least 10 Business Days prior to the anticipated filing date of such Shelf Registration to the other Stockholders, and such notice shall describe the proposed Shelf Registration, the intended method of disposition of such Registrable Securities and any other information that at the time would be appropriate to include in such notice, and offer such Stockholders the opportunity to register the number of Registrable Securities as each such Stockholder may request in writing to the Company, given within 10 Business Days after such Stockholders receive the Company’s notice of the Shelf Registration. The “Plan of Distribution” section of such Shelf Registration shall permit all lawful means of disposition of Registrable Securities, including firm-commitment underwritten public offerings, block trades, agented transactions, sales directly into the market, purchases or sales by brokers and sales not involving a public offering. With respect to each Shelf Registration, the Company shall, subject to any Suspension Period, (i) as promptly as practicable after the written request of the Requesting Stockholder, file a Registration Statement and (ii) use its commercially reasonable efforts to cause such Registration Statement to be declared effective as promptly as practicable, and remain effective until the date set forth in Section 2.04(a)(ii) . No Stockholder shall be entitled to include any of its Registrable Securities in a Shelf Registration unless such

10

Stockholder has complied with Section 2.15 . The Company shall not be required to amend a Shelf Registration (or the related prospectus) to add or change the disclosure regarding selling securityholders during any Suspension Period. The obligations set forth in this Section 2.02(a) shall not apply if the Company has a currently effective Automatic Shelf Registration Statement covering all Registrable Securities in accordance with Section 2.02(f) and has otherwise complied with its obligations pursuant to this Agreement.

(b) Upon written request by a Requesting Stockholder holding Shelf Registered Securities (such Stockholder, the “ Shelf Public Offering Requesting Stockholder ”), which request (the “ Shelf Public Offering Request ”) shall specify the class or series and amount of such Shelf Public Offering Requesting Stockholder’s Shelf Registered Securities to be sold (the “ Requested Shelf Registered Securities ”), the Company shall (subject to any Suspension Period) perform its obligations hereunder with respect to the sale of such Requested Shelf Registered Securities in the form of a firm commitment underwritten public offering (unless otherwise consented to by the Shelf Public Offering Requesting Stockholder) (a “ Shelf Public Offering ”) if the aggregate proceeds expected to be received from the sale of the Requested Shelf Registrable Securities equals or exceeds $25,000,000. Promptly upon receipt of a Shelf Public Offering Request, the Company shall provide notice (the “ Shelf Public Offering Notice ”) of such proposed Shelf Public Offering (which notice shall state the material terms of such proposed Shelf Public Offering, to the extent known, as well as the identity of the Shelf Public Offering Requesting Stockholder) to the other Stockholders holding Shelf Registered Securities. Such other Stockholders may, by written request to the Company and the Shelf Public Offering Requesting Stockholder, within two Business Days after receipt of such Shelf Public Offering Notice, include up to all of their Shelf Registered Securities of the same class or series as the Requested Shelf Registration Securities in such proposed Shelf Public Offering; provided , that any such Shelf Registered Securities shall be sold subject to the same terms as are applicable to the Shelf Registered Securities of the Shelf Public Offering Requesting Stockholder. No Stockholder shall be entitled to include any of its Registrable Securities in a Shelf Public Offering unless such Stockholder has complied with Section 2.15 . The lead managing underwriter or underwriters selected for such Shelf Public Offering shall be selected in accordance with Section 2.04(f)(i) .

(c) In a Shelf Public Offering, if the lead managing underwriter advises the Company and the Shelf Public Offering Requesting Stockholder that, in its view, the number of shares of Registrable Securities requested to be included in such Shelf Public Offering (including any securities that the Company proposes to be included that are not Registrable Securities) exceeds the Maximum Offering Size, the Company shall include in such Shelf Public Offering, in the priority listed below, up to the Maximum Offering Size:

(i) first, all Shelf Registered Securities requested to be included in the Shelf Public Offering by the Shelf Public Offering Requesting Stockholder and all other Stockholders, pro rata on the basis of the relative number of shares of Shelf Registered Securities so requested to be included in the Shelf Public Offering by each such Stockholder;

11

(ii) second, any securities proposed to be included in the Shelf Public Offering by the Company; and

(iii) third, any securities proposed to be included in the Shelf Public Offering for the account of any other Persons, with such priorities among them as the Company shall determine.

(d) The Company shall use its commercially reasonable efforts to cooperate in a timely manner with any request of the Stockholders in respect of any block trade, hedging transaction or other transaction that is registered pursuant to a Shelf Registration that is not a firm commitment underwritten offering (each, an “ Alternative Transaction ”), including, without limitation, entering into customary agreements with respect to such Alternative Transactions (and providing customary representations, warranties, covenants and indemnities in such agreements) as well as providing other reasonable assistance in respect of such Alternative Transactions of the type applicable to a Public Offering subject to Section 2.04 , to the extent customary for such transactions. The Company shall bear all Registration Expenses in connection with any Shelf Registration, any Shelf Public Offering or any other transaction (including any Alternative Transaction) registered under a Shelf Registration pursuant to this Section 2.02 , whether or not such Shelf Registration becomes effective or such Shelf Public Offering or other transactions is completed; provided, however, that if the Shelf Public Offering Requesting Stockholder revokes its request in whole with respect to a Shelf Public Offering, then the Shelf Public Offering Requesting Stockholder shall reimburse the Company for and/or pay directly all Registration Expenses incurred relating to such Shelf Public Offering.

(e) After the Registration Statement with respect to a Shelf Registration is declared effective but subject to the Suspension Period, upon written request by one or more Stockholders (which written request shall specify the amount of such Stockholders’ Registrable Securities to be registered), the Company shall, as promptly as practicable after receiving such request, (i) if it is a Seasoned Issuer or Well-Known Seasoned Issuer, or if such Registration Statement is an Automatic Shelf Registration Statement, file a prospectus supplement to include such Stockholders as selling stockholders in such Registration Statement or (ii) if it is not a Seasoned Issuer or Well-Known Seasoned Issuer, and the Registrable Securities requested to be registered represent more than 5% of the outstanding Registrable Securities and the aggregate proceeds expected to be received from the sale thereof is at least $10,000,000, file a post-effective amendment to the Registration Statement to include such Stockholders in such Shelf Registration and use commercially reasonable efforts to have such post-effective amendment declared effective.

(f) Upon the Company becoming aware that it is a Well-Known Seasoned Issuer, (i) the Company shall give written notice to all of the Stockholders as promptly as practicable but in no event later than 20 Business Days thereafter, and such notice shall describe, in reasonable detail, the basis on which the Company has become a Well-Known Seasoned Issuer, and (ii) the Company shall, as promptly as practicable and subject to any Suspension Period, register, under an Automatic Shelf Registration Statement, the sale of all of the Registrable Securities in accordance with the terms of this Agreement. The Company shall use its commercially

12

reasonable efforts to file such Automatic Shelf Registration Statement as promptly as practicable, but in no event later than fifteen (15) Business Days after it becomes a Well-Known Seasoned Issuer, and to cause such Automatic Shelf Registration Statement to remain effective thereafter until the date set forth in Section 2.04(a)(ii) . The Company shall give written notice of filing such Registration Statement to all of the Stockholders as promptly as practicable thereafter. The Company shall not be required to include any Stockholder as a Selling Stockholder in any Registration Statement or prospectus unless such Stockholder has complied with Section 2.15 . At any time after the filing of an Automatic Shelf Registration Statement by the Company, if it is reasonably likely that it will no longer be a Well-Known Seasoned Issuer as of a future determination date (the “ Determination Date ”), at least 30 days prior to such Determination Date, the Company shall (A) give written notice thereof to all of the Stockholders as promptly as practicable but in no event later than ten (10) Business Days prior to such Determination Date and (B) if the Company is eligible to file a Registration Statement on Form S-3 with respect to a secondary public offering of its equity securities, file a Registration Statement on Form S-3 with respect to a Shelf Registration in accordance with Section 2.02(a) , treating all selling stockholders identified as such in the Automatic Shelf Registration Statement (and amendments or supplements thereto) as Requesting Stockholders and use all commercially reasonable efforts to have such Registration Statement declared effective prior to the Determination Date.

the extent requisite to permit the disposition of the Registrable Securities so to be registered in accordance with the plan of distribution intended by the Company for such registration statement; provided that (i) if such registration involves a Public Offering, all such Registering Stockholders requesting to be included in the Company’s registration must sell their Registrable Securities to the underwriters selected as provided in Section 2.04(f)(i) on the same terms and conditions as apply to the Company and (ii) if, at any time after giving notice of its intention to register any Company Securities pursuant to this Section 2.02(h) and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register such securities, the Company shall give notice to all Registering Stockholders and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration. No registration effected under this Section 2.02 shall relieve the Company of its obligations to effect a Demand Registration or Shelf Registration to the extent required by Section 2.01 . The Company shall pay all Registration Expenses in connection with each Piggyback Registration.

(ii) If a Piggyback Registration involves a Public Offering (other than any Demand Registration, in which case the provisions with respect to priority of inclusion in such offering set forth in Section 2.01(e) shall apply) and the lead managing underwriter advises the Company that, in its view, the number of Registrable Securities that the Company and such Registering Stockholders intend to include in such registration exceeds the Maximum Offering Size, the Company shall include in such registration, in the following priority, up to the Maximum Offering Size:

(A) first, so much of the Registrable Securities proposed to be registered for the account of the Company as would not cause the offering to exceed the Maximum Offering Size;

(B) second, all Registrable Securities requested to be included in such registration by any Registering Stockholders pursuant to this Section 2.02 (allocated, if necessary for the offering not to exceed the Maximum Offering Size, pro rata among such Stockholders on the basis of the relative number of shares of Registrable Securities so requested to be included in such registration by each such Stockholder); and

(C) third, any securities proposed to be registered for the account of any other Persons with such priorities among them as the Company shall determine.

(i) Hedging Transactions .

(i) The Company agrees that, in connection with any proposed Hedging Transaction, if, in the reasonable judgment of Holders’ Counsel, it is necessary or desirable to register under the Securities Act such Hedging Transaction or sales or transfers (whether short or long) of Registrable Class Securities in connection therewith,

14

then the Company shall use its commercially reasonable efforts to take such actions (which may include, among other things, the filing of a post-effective amendment to a Registration Statement to include additional or changed information that is material or is otherwise required to be disclosed, including a description of such Hedging Transaction, the name of the Hedging Counterparty, identification of the Hedging Counterparty or its Affiliates as underwriters or potential underwriters, if applicable, or any change to the plan of distribution) as may reasonably be required to register such Hedging Transaction or sales or transfers of Registrable Class Securities in connection therewith under the Securities Act in a manner consistent with the rights and obligations of the Company hereunder with respect to the registration of Registrable Securities. Any information provided by the Stockholders regarding the Hedging Transaction that is included in a Registration Statement, Prospectus or Free Writing Prospectus pursuant to this Section 2.02(h) shall be deemed to be information provided by the Registering Stockholders pursuant to such Registration Statement for purposes of Section 2.14 .

(ii) All Registration Statements in which Stockholders may include Registrable Securities under this Agreement shall be subject to the provisions of this Section 2.02(h) , and the registration of Registrable Class Securities thereunder pursuant to this Section 2.02(h) shall be subject to the provisions of this Agreement applicable to any such Registration Statements; provided , however , that the selection of any Hedging Counterparty shall not be subject to Section 2.04(f) , but the Hedging Counterparty shall be selected by the holders of a majority of the Registrable Class Securities subject to the Hedging Transaction that are proposed to be included in such Registration Statement.

(iii) If in connection with a Hedging Transaction, a Hedging Counterparty or any Affiliate thereof is (or may be considered) an underwriter or selling stockholder, then it shall be required to provide customary indemnities to the Company regarding the plan of distribution and like matters.

(iv) The Company further agrees to include, under the caption “Plan of Distribution” (or the equivalent caption), in each Registration Statement, and any related Prospectus (to the extent such inclusion is permitted under applicable Commission regulations and is consistent with comments received from the Commission during any Commission review of the Registration Statement), language substantially in the form of Schedule 2 hereto and to include in each Prospectus supplement filed in connection with any proposed Hedging Transaction language mutually agreed upon by the Company, the relevant Stockholders and the Hedging Counterparty describing such Hedging Transaction.

Section 2.03. Lock-Up Agreements. (a) Each Stockholder hereby agrees that it will not effect any public sale or distribution (including sales pursuant to Rule 144) of Registrable Securities, (i) during (A) the 10 days prior to and the 90-day period beginning on the effective date of the registration of such Registrable Securities in connection with a Public Offering (which period following the effective date may, in each case, be extended to the extent required by applicable law, rule or regulation) or (B) such shorter period as the underwriters participating

15

in such Public Offering may require, and (ii) upon notice from the Company of the commencement of a Public Offering in connection with any Shelf Registration, during (A) 10 days prior to and the 90-day period beginning on the date of commencement of such Public Offering or (B) such shorter period as the underwriters participating in such Public Offering may require, in each case except as part of such Public Offering. Each Stockholder agrees to execute a lock-up agreement in favor of the underwriters in form and substance reasonably acceptable to the Company and the underwriters to such effect and, in any event, that the underwriters in any relevant offering shall be third party beneficiaries of this Section 2.03(a) . The lock-up agreement to be executed by each Stockholder pursuant to this Section 2.03(a) shall be no less favorable to such Stockholder than the lock-up agreements (or provisions in any underwriting agreement) executed by the Company or any of the executive officers or directors of the Company pursuant to Section 2.03(b) .

(b) The Company shall not effect any public sale or distribution of Registrable Securities (except pursuant to registrations on Form S-8 or Form S-4), (i) with respect to any Public Offering pursuant to a Demand Registration or any Piggyback Registration in which the holders of Registrable Securities are participating, during (A) the 10 days prior to and the 90-day period beginning on the effective date of such registration (which period following the effective date may, in each case, be extended to the extent required by applicable law, rule or regulation) or (B) such shorter period as the underwriters participating in such Public Offering may require, and (ii) upon notice from any holder(s) of Registrable Securities subject to a Shelf Registration that such holder(s) intend to effect a Public Offering of Registrable Securities pursuant to such Shelf Registration (upon receipt of which, the Company will promptly notify all other Stockholders of the date of commencement of such Public Offering), during (A) the 10 days prior to and the 90-day period beginning on the date of commencement of such Public Offering and (B) such shorter period as the underwriters participating in such Public Offering may require), in each case except as part of such Public Offering. To the extent required by any underwriter participating in such Public Offering, the Company shall use commercially reasonable efforts to cause its executive officers and directors to execute customary lock-up agreements in connection with such Public Offering, which lock-up agreements shall not have a duration shorter than that of the lock-up agreement or provisions applicable to the Company.

Section 2.04. Registration Procedures . Whenever a Stockholder requests that any Registrable Securities be registered pursuant to Section 2.01 or 2.02 , subject to the provisions of such Sections, the Company shall use its commercially reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof as soon as reasonably practicable, and, in connection with any such request:

(a) The Company shall as soon as reasonably practicable prepare and file with the SEC a Registration Statement on any form for which the Company then qualifies or that counsel for the Company shall deem appropriate and which form shall be available for the sale of the Registrable Securities to be registered thereunder in accordance with the intended method of distribution thereof, and use its commercially reasonable efforts to cause such filed Registration Statement to become and remain effective for a period of (i) not less than 180 days (or, if sooner, until all Registrable Securities have been sold under such Registration Statement), or (ii) in the

16

case of a Shelf Registration, until the earlier of the date (x) on which all of the securities covered by such Shelf Registration are no longer Registrable Securities and (y) on which the Company cannot extend the effectiveness of such Shelf Registration because it is no longer eligible for use of Form S-3; subject in each case to any Suspension Period.

(b) Prior to filing a Registration Statement or related prospectus or any amendment or supplement thereto (including any documents incorporated by reference therein), or before using any Free Writing Prospectus, the Company shall provide to each Registering Stockholder, the Holders’ Counsel and each underwriter, if any, with an adequate and appropriate opportunity to review and comment on such Registration Statement, each Prospectus included therein (and each amendment or supplement thereto) and each Free Writing Prospectus proposed to be filed with the SEC, and thereafter the Company shall furnish to such Registering Stockholder, the Holders’ Counsel and underwriter, if any, such number of copies of such Registration Statement, each amendment and supplement thereto filed with the SEC (in each case including all exhibits thereto and documents incorporated by reference therein), the prospectus included in such Registration Statement (including each preliminary prospectus and any summary prospectus) and any other prospectus filed under Rule 424, Rule 430A, Rule 430B or Rule 430C under the Securities Act and such other documents as such Registering Stockholder or underwriter may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Registering Stockholder; provided , however , that in no event shall the Company be required to provide to any Person any materials, information or document required to be filed by the Company pursuant to the Exchange Act prior to its filing other than in connection with a Public Offering. In addition, the Company shall, as expeditiously as practicable, keep Holders’ Counsel advised in writing as to the initiation and progress of any registration under Sections 2.01 and 2.02 and provide Holders’ Counsel with copies of all correspondence (including any comment letter) with the SEC, any self regulatory organization or other governmental agency in connection with any such Registration Statement. Each Registering Stockholder shall have the right to request that the Company modify any information contained in such Registration Statement, amendment and supplement thereto pertaining to such Registering Stockholder and the Company shall use its commercially reasonable efforts to comply with such request; provided, however , that the Company shall not have any obligation so to modify any information if the Company reasonably expects that so doing would cause the prospectus to contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading.

(c) After the filing of the Registration Statement, the Company shall (i) cause the related prospectus to be supplemented by any required prospectus supplement, and, as so supplemented, to be filed pursuant to Rule 424 under the Securities Act, (ii) comply with the provisions of the Securities Act applicable to the Company with respect to the disposition of all Registrable Securities covered by such Registration Statement during the applicable period in accordance with the intended methods of disposition by the Registering Stockholder thereof set forth in such Registration Statement or supplement to such prospectus and (iii) promptly notify each Registering Stockholder holding Registrable Securities covered by such Registration Statement and the Holders’ Counsel of any stop order issued or threatened by the SEC or any state securities commission and take all commercially reasonable actions required to prevent the entry of such stop order or to remove it if entered.

17

(d) The Company shall use its commercially reasonable efforts to (i) register or qualify the Registrable Securities covered by such Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as any Registering Stockholder holding such Registrable Securities reasonably (in light of such Registering Stockholder’s intended plan of distribution) requests, and continue such registration or qualification in effect in such jurisdiction for the shortest of (A) as long as permissible pursuant to the laws of such jurisdiction, (B) as long as any such Registering Stockholder requests or (C) until all such Registrable Securities are sold and (ii) cause such Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be reasonably necessary or advisable to enable such Registering Stockholder to consummate the disposition of the Registrable Securities owned by such Registering Stockholder; provided that the Company shall not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 2.04(d) , (B) subject itself to taxation in any such jurisdiction or (C) consent to general service of process in any such jurisdiction.

(e) The Company shall promptly notify each Registering Stockholder holding such Registrable Securities covered by such Registration Statement (i) at any time when a prospectus relating thereto is required to be delivered under the Securities Act, upon the discovery that, or upon the occurrence of an event as a result of which, the preparation of a supplement or amendment to such prospectus is required so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and the Company shall promptly (subject to any applicable Suspension Period) prepare and make available to each Registering Stockholder and file with the SEC any such supplement or amendment, (ii) as soon as the Company becomes aware of any request by the SEC or any Federal or state governmental authority for amendments or supplements to a Registration Statement or related prospectus covering Registrable Securities or for additional information relating thereto, (iii) as soon as the Company becomes aware of the issuance or threatened issuance by the SEC of any stop order suspending or threatening to suspend the effectiveness of a Registration Statement covering the Registrable Securities or (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose.

(f) (i) The Registering Stockholders holding a majority of the Registrable Securities to be included in a Demand Registration or intended to be sold pursuant to a Public Offering pursuant to a “take down” under a Shelf Registration shall have the right to select an underwriter or underwriters in connection with such Public Offering or “take down” (as the case may be) (which underwriter or underwriters may include any Affiliate of any Registering Stockholder so long as including such Affiliate would not require the separate engagement of a qualified

18

independent underwriter with respect to such offering), subject to the Company’s approval (which shall not be unreasonably withheld, conditioned or delayed) and (ii) the Company shall select an underwriter or underwriters in connection with any other Public Offering. In connection with any Public Offering, the Company shall enter into customary agreements (including an underwriting agreement in customary form) and take all other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities in any such Public Offering, including, if required, the engagement of a “qualified independent underwriter” in connection with the qualification of the underwriting arrangements with the FINRA.

(g) Upon the implementation of confidentiality arrangements in form and substance reasonably satisfactory to the Board, the Company shall make available for inspection by any Registering Stockholder and any underwriter participating in any disposition pursuant to a Registration Statement being filed by the Company pursuant to this Section 2.04 and any attorney, accountant or other professional retained by any such Stockholder or underwriter (collectively, the “ Inspectors ”), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “ Records ”) as shall be reasonably necessary or desirable to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any Inspectors in connection with such Registration Statement. Records that the Company determines, in good faith, to be confidential and that it notifies the Inspectors are confidential shall not be disclosed by the Inspectors unless (i) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in such Registration Statement, (ii) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction, (iii) disclosure of such Records is necessary to comply with federal or state securities laws or the rules of any securities exchange or trading market on which the Common Stock is listed or traded or is otherwise required by law, rule, regulation or legal process, (iv) the information in such Records was known to the Inspectors on a non-confidential basis prior to its disclosure by the Company or has been made generally available to the public, (v) the information in such Records is or becomes available to the public other than as a result of disclosure by any Inspector in violation the confidentiality agreements or (vi) is or was independently developed by any Inspector without the benefit of the information in such Records. Each Registering Stockholder agrees that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it or its Affiliates for any other purpose, including as the basis for any market transactions in any securities of the Company, unless and until such information is made generally available to the public. Each Registering Stockholder further agrees that, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, it shall give notice to the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential.

(h) The Company shall furnish to each Registering Stockholder and to each such underwriter, if any, a signed counterpart, addressed to such Registering Stockholder or underwriter, of (i) an opinion or opinions of counsel to the Company and (ii) a comfort letter or comfort letters from the Company’s independent public accountants, each in customary form and

19

covering such matters of the kind customarily covered by opinions or comfort letters, as the case may be, any Registering Stockholder or the lead managing underwriter therefor reasonably requests.

(i) The Company shall otherwise comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably available, an earnings statement or such other document that shall satisfy the provisions of Section 11(a) of the Securities Act and the requirements of Rule 158 thereunder.

(j) The Company may require each Registering Stockholder promptly to furnish in writing to the Company such information regarding the distribution of the Registrable Securities as the Company may from time to time reasonably request and such other information as may be reasonably required in connection with such registration.

(k) Each Registering Stockholder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.04(e) , such Stockholder shall forthwith discontinue disposition of Registrable Securities pursuant to the Registration Statement (including any Shelf Registration) covering such Registrable Securities until such Stockholder’s receipt of (i) copies of the supplemented or amended prospectus from the Company or (ii) further notice from the Company that distribution can proceed without an amended or supplemented prospectus, and, in the circumstances described in clause (i) , if so directed by the Company, such Stockholder shall deliver to the Company all copies, other than any permanent file copies then in such Stockholder’s possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice. If the Company shall give such notice, the Company shall extend the period during which such registration statement shall be maintained effective (including the period referred to in Section 2.04(a)) by the number of days during the period from and including the date of the giving of notice pursuant to Section 2.04(e) to the date when the Company shall (x) make available to such Stockholder a prospectus supplemented or amended to conform with the requirements of Section 2.04(e) or (y) deliver to such Stockholder the notice described in clause (ii) .

(l) The Company shall use its commercially reasonable efforts to list all Registrable Securities of any class or series covered by such Registration Statement on any national securities exchange on which any of the Registrable Securities of such class or series are then listed or traded.

(m) With respect to not more than five offerings of Registrable Securities, upon written request (which notice shall be given with reasonable advance notice) to the Company by Registering Stockholders holding a majority of the Registrable Securities being sold in such offering, the Company shall have appropriate officers of the Company (i) upon reasonable request and at reasonable times prepare and make presentations at any “road shows” and before analysts and rating agencies, as the case may be, (ii) take other actions to obtain ratings for any Registrable Securities and (iii) otherwise use its commercially reasonable efforts to cooperate as requested by the underwriters in the offering, marketing or selling of the Registrable Securities.

20

(n) The Company shall as soon as possible following its actual knowledge thereof, notify each Registering Stockholder: (A) when a prospectus, any prospectus supplement, a Registration Statement or a post-effective amendment to a Registration Statement has been filed with the SEC, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective; (B) of any request by the SEC or any other federal or state governmental authority for amendments or supplements to a Registration Statement, a related prospectus (including a Free Writing Prospectus) or for any other additional information; or (C) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceedings for such purpose.

(o) The Company shall reasonably cooperate with each Registering Stockholder and each underwriter participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made by FINRA.

(p) The Company shall take all other steps reasonably necessary to effect the registration of such Registrable Securities and reasonably cooperate with the holders of such Registrable Securities to facilitate the disposition of such Registrable Securities.

(q) The Company shall, within the deadlines specified by the Securities Act, make all required filings of all prospectuses (including any Free Writing Prospectus) with the SEC and make all required filing fee payments in respect of any Registration Statement or related prospectus used under this Agreement (and any offering covered hereby).

(r) The Company shall, if such registration is pursuant to a Registration Statement on Form S-3 or any similar short-form registration, include in such Registration Statement such additional information for marketing purposes as the managing underwriter with respect to an underwritten public offering reasonably requests.

Section 2.05. Indemnification by the Company . The Company agrees to indemnify and hold harmless each Registering Stockholder holding Registrable Securities covered by a Registration Statement, its partners, Affiliates, stockholders, members, officers, directors, employees, partners and agents, and each Person, if any, who controls such Registering Stockholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively, “ Stockholder Parties ”) from and against any and all losses, claims, damages, liabilities and expenses (including reasonable expenses of investigation and reasonable attorneys’ fees and expenses) (“ Damages ”) caused by or relating to any untrue statement or allegedly untrue statement of a material fact contained in any Registration Statement or prospectus relating to the Registrable Securities (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus or Free Writing Prospectus relating to the Registrable Securities (including any information that has been deemed to be a part of any prospectus under Rule 159 under the Securities Act), or caused by or relating to any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however , that the Company shall not be liable to any Stockholder Party for any Damages that are caused

21

by or related to any such untrue statement or omission or alleged untrue statement or omission so made based upon information furnished in writing to the Company by or on behalf of such Registering Stockholder expressly for use therein. The Company also agrees to indemnify and hold harmless any underwriters of the Registrable Securities, their respective officers and directors and each Person who controls any underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act on substantially the same basis as that of the indemnification of the Registering Stockholders provided in this Section 2.05 .

Section 2.06. Indemnification by Registering Stockholders . Each Registering Stockholder holding Registrable Securities included in any Registration Statement agrees, severally but not jointly, to indemnify and hold harmless (i) the Company, (ii) each Person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, (iii) each other Registering Stockholder participating in any offering of Registrable Securities and (iv) the respective partners, Affiliates, stockholders, members, officers, directors, employees, partners and agents of each of the Persons specified in clauses (i)  through (iii)  from and against all Damages to the same extent as the foregoing indemnity from the Company to such Registering Stockholder, but only with respect to information furnished in writing by or on behalf of such Registering Stockholder expressly for use in any Registration Statement or prospectus relating to the Registrable Securities, or any amendment or supplement thereto, or any preliminary prospectus or Free Writing Prospectus relating to the Registrable Securities (including any information that has been deemed to be a part of any prospectus under Rule 159 under the Securities Act). Each Registering Stockholder also agrees to indemnify and hold harmless any underwriters of the Registrable Securities, their respective officers and directors and each Person who controls any underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act on substantially the same basis as that of the indemnification of the Company and the other Registering Stockholders provided in this Section 2.06 . As a condition to including Registrable Securities in any Registration Statement filed in accordance with Article 2 , the Company may require that it shall have received an undertaking reasonably satisfactory to it from any underwriter to indemnify and hold the Company harmless to the extent customarily provided by underwriters with respect to similar securities and offerings. No Registering Stockholder shall be liable under this Section 2.06 for any Damages in excess of the net proceeds (after deducting the underwriters’ discounts and commissions) realized by such Registering Stockholder in the sale of Registrable Securities of such Registering Stockholder to which such Damages relate.

Section 2.07. Conduct of Indemnification Proceedings . If any proceeding (including any investigation by any governmental authority) shall be instituted involving any Person in respect of which indemnity may be sought pursuant to Section 2.05 or 2.06 , such Person (an “ Indemnified Party ”) shall promptly notify the Person against whom such indemnity may be sought (the “ Indemnifying Party ”) in writing and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all reasonable fees and expenses; provided that the failure of any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Party

22

shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel; (ii) in the reasonable judgment of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them; or (iii) the Indemnified Party shall have 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 Indemnifying Party. It is understood that, in connection with any proceeding or related proceedings in the same jurisdiction, the Indemnifying Party shall not be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties, and that all such fees and expenses shall be reimbursed promptly after receipt of a invoice setting forth such fees and expenses in reasonable detail. In the case of any such separate firm for the Indemnified Parties, such firm shall be designated in writing by the Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent, or if there be a final judgment for the plaintiff, the Indemnifying Party shall indemnify and hold harmless such Indemnified Parties from and against any Damages (to the extent obligated herein) by reason of such settlement or judgment. Without the prior written consent of the Indemnified Party, no Indemnifying Party shall effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such proceeding.

Section 2.08. Contribution . If the indemnification provided for in Section 2.05 or 2.06 is unavailable to the Indemnified Parties or insufficient in respect of any Damages caused by or relating to any untrue statement or allegedly untrue statement of a material fact contained in any Registration Statement or prospectus relating to the Registrable Securities (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus or Free Writing Prospectus relating to the Registrable Securities (including any information that has been deemed to be a part of any prospectus under Rule 159 under the Securities Act), or caused by or relating to any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Damages in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and the Indemnified Parties in connection with such actions which resulted in such Damages, as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and the Indemnified Parties shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action.

23

The parties agree that it would not be just and equitable if contribution pursuant to this Section 2.08 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 the immediately preceding paragraph. The amount paid or payable by a party as a result of the Damages referred to in the preceding paragraph shall be deemed to include, subject to the limitations set forth in Sections 2.05 and 2.06, any legal or other expenses reasonably incurred by a party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 2.08 , no Registering Stockholder shall be required to contribute any amount in excess of the net proceeds (after deducting the underwriters’ discounts and commissions) received by such Registering Stockholder in the offering. 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. Each Registering Stockholder’s obligation to contribute pursuant to this Section 2.08 is several in the proportion that the net proceeds of the offering received by such Registering Stockholder bears to the net total proceeds of the offering received by all such Registering Stockholders and not joint.

Section 2.09. Participation in Public Offering . No Stockholder may participate in any Public Offering hereunder unless such Stockholder (i) agrees to sell such Stockholder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements 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 and the provisions of this Agreement in respect of registration rights.

Section 2.10. Other Indemnification . Indemnification similar to that specified herein (with appropriate modifications) shall be given by the Company and each Registering Stockholder participating therein with respect to any required registration or other qualification of securities under any federal or state law or regulation or governmental authority other than the Securities Act.

Section 2.11. Cooperation by the Company . At any time following the Initial Public Offering, if any Stockholder shall transfer, assign, sell, convey or otherwise dispose of any Registrable Securities pursuant to Rule 144, the Company shall reasonably cooperate (subject to the terms and conditions of the Certificate of Incorporation) with such Stockholder, provide to such Stockholder such information as such Stockholder shall reasonably request and make publicly available information necessary to permit sales pursuant to Rule 144 for so long as necessary.

Section 2.12. Transfer of Registration Rights . The rights of a Stockholder under this Article II may be transferred or assigned in connection with a transfer of Registrable Securities provided that all of the following additional conditions are satisfied: (x) such transfer or assignment is effected in accordance with applicable securities laws and (y) the Company is given written notice by such transferor of such transfer or assignment, stating the name and address of the transferee or assignee and identifying the amount of Registrable Securities with respect to which such rights are being transferred or assigned and (z) such transferee or assignee executes and delivers to the Company an agreement to be bound by this Agreement in the form of Exhibit A.

24

Section 2.13. Limitations on Subsequent Registration Rights . The Company agrees that it shall not enter into any agreement with any holder or prospective holder of any securities of the Company (i) that would allow such holder or prospective holder to include such securities in any Demand Registration, Piggyback Registration or Shelf Registration 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 their inclusion would not be on terms more favorable in the aggregate to such holder or prospective holder than this Agreement.
