ARTICLE 2

REGISTRATION RIGHTS

Section 2.1 Registration.

(a) Registration Statement. Subject to the terms and conditions of this Agreement, as soon as reasonably practicable after the date hereof, but in any event no later than the applicable Filing Deadline, the Company will prepare and file a registration statement on Form S-3 (or such other appropriate registration statement form of the SEC if a registration statement on Form S-3 is not then available to the Company) with the SEC for the resale of the Registrable Shares (the “Resale Shelf S-3”). The Company shall use its commercially reasonable efforts to (a) have the Resale Shelf S-3 declared effective on or prior to the applicable Effectiveness Deadline, including by filing an automatic shelf registration statement that becomes effective upon filing with the SEC in accordance with Rule 462(e) under the Securities Act to the extent the Company is then a WKSI, and (b) cause the Resale Shelf S-3 to continue to be effective until the expiration of the applicable Effectiveness Period. For avoidance of doubt, the Company’s obligations hereunder shall include the filing of all amendments, post-effective amendments and supplements to the Resale Shelf S-3 and the prospectus used therein as may be necessary to keep such Resale Shelf S-3 effective throughout the applicable Effectiveness Period and comply with the Securities Act with respect to the disposition of all Registrable Shares during such period, as required pursuant to Section 2.6(a).

(b) Liquidated Damages. If any Registration Statement (other than any Registration Statement with respect to an Underwritten Registration or a Piggyback Registration) (i) is not filed with the SEC on or prior to the applicable Filing Deadline, (ii) is not declared effective by the SEC (or otherwise does not become effective) for any reason on or prior to the applicable Effectiveness Deadline, or (iii) does not remain effective for the applicable Effectiveness Period for any reason (any such failure or breach in clauses (i) through (iii) above being referred to as an “Event,” and, the date on which such Event occurs being referred to as an

“Event Date”), then in addition to any other rights the Holders may have hereunder or under applicable law, from the Event Date, for each day that the Event continues, the Company shall pay the Holders with respect to such Event, as liquidated damages and not as a penalty, an amount in cash equal to 1.00% of the product of (x) the number of shares representing the Equity Purchase Price and (y) the Weighted Share Price, per calendar month or portion thereof prior to the cure of such Event (the “Liquidated Damages”). Notwithstanding the foregoing, the maximum payment of Liquidated Damages to any Holder associated with all Events in the aggregate shall not exceed 5.00% of the product of (x) the number of shares representing the Equity Purchase Price and (y) the Weighted Share Price. The Company’s obligation to pay Liquidated Damages other than partial Liquidated Damages owing but not yet paid shall terminate at such time as the registration rights granted by this Agreement terminate in accordance with Section 3.1.

(c) SEC Modification of Offering Size. If at any time the SEC takes the position that the offering of some or all of the Registrable Shares on the Resale Shelf S-3 is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the Securities Act or requires any Holder to be named as an “underwriter”, the Company shall use its commercially reasonable efforts to persuade the SEC that the offering contemplated by the Resale Shelf S-3 is a valid secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 and that none of the Holders is an “underwriter”. The Holders shall have the right to participate or have their counsel participate in any meetings or discussions with the SEC regarding the SEC’s position and to comment or have their counsel comment on any written submission made to the SEC with respect thereto. No such written submission shall be made to the SEC to which the Holders’ counsel reasonably objects. In the event that, despite the Company’s commercially reasonable efforts and compliance with the terms of this Section 2.1(c), the SEC refuses to alter its position, the Company shall (i) remove from the Resale Shelf S-3 such portion of the Registrable Shares objected to by the SEC (the “Cut Back Shares”) and/or (ii) agree to such restrictions and limitations on the registration and resale of the Registrable Shares as the SEC may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall not agree to name any Holder as an “underwriter” in such Resale Shelf S-3 without the prior written consent of such Holder. Any cut-back imposed on the Holders pursuant to this Section 2.1(c) shall be allocated among the Holders on a pro rata basis, unless the SEC Restrictions otherwise require or provide or the Holders otherwise agree. On or prior to the applicable Effectiveness Deadline, the Company shall have one or more registration statements on Form S-3 declared effective covering the resale of the Cut Back Shares (each an “Additional Registration Statement”). For the avoidance of doubt, the Liquidated Damages described above shall not begin to accrue with respect to such Cut Back Shares until after the applicable Effectiveness Deadline.

Section 2.2 Underwritten Registrations and Shelf Takedowns.

(a) Request for Underwritten Registration. At any time after the date of this Agreement, any Demanding Stockholder shall have the right to require the Company to file a registration statement on Form S-3 or any similar form or successor to such form under the Securities Act, or any other appropriate form under the Securities Act or the Exchange Act for an underwritten public offering of all or part of its Registrable Shares (an “Underwritten

Registration”), by delivering to the Company written notice stating that such right is being exercised, naming the Demanding Stockholder(s) whose Registrable Shares are to be included in such registration, specifying the aggregate number of the Demanding Stockholder’s Registrable Shares to be included in such registration and, subject to Section 2.2(e) hereof, describing the intended method of distribution thereof to the extent then known (a “Demand Request”).

(b) Required Filing Date. Subject to Section 2.2(h), the Company shall file the Registration Statement in respect of an Underwritten Registration as soon as practicable and, in any event, within sixty (60) days after receiving a Demand Request (the “Required Filing Date”) on any form for which the Company then qualifies, and which form shall be available for the sale of the Registrable Shares in accordance with the intended methods of distribution thereof, and shall use commercially reasonable efforts to cause the same to be declared effective by the SEC on or before the applicable Effectiveness Deadline; provided that the Company shall not be obligated to effect (i) more than two Underwritten Registrations or Shelf Takedowns pursuant to Section 2.2 in any 365-day period or (ii) more than four (4) additional Underwritten Registrations or Shelf Takedowns pursuant to Section 2.2 in the aggregate, in each case, during the term of this Agreement for Demand Requests made by Demanding Stockholders that, together with their Affiliates, beneficially own (as contemplated by Rule 13d-3 of the Exchange Act) 5,700,000 or less of Registrable Shares at the time of the Demand Request.

(c) Shelf Registration. With respect to any Underwritten Registration, subject to the availability of a registration statement on Form S-3 or any similar form or successor to such form under the Securities Act, including an “automatic” shelf registration statement to the extent available to the Company, the Company shall, upon written request from a Demanding Stockholder, agree to effect a registration of the Registrable Shares in a continuous offering pursuant to Rule 415 under the Securities Act (or any successor rule) (a “Shelf Registration”), and, thereafter, shall use commercially reasonable efforts to cause such Registration Statement to be declared effective under the Securities Act on or before the applicable Effectiveness Deadline.

(d) Request for Shelf Takedown.

(i) At any time that a Resale Shelf S-3 is effective, any Demanding Stockholder shall have the right to require the Company to facilitate the sale of all or a portion of its Registrable Shares included in the Resale Shelf S-3 in an underwritten public offering, including a bought or overnight offering (a “Shelf Takedown”), by delivering to the Company written notice stating that such right is being exercised, naming the Demanding Stockholder(s) whose Registrable Shares are to be included in such Shelf Takedown, specifying the aggregate number of the Demanding Stockholder’s Registrable Shares to be included in such Shelf Takedown and, subject to Section 2.2(e) hereof, describing the intended method of distribution thereof to the extent then known (a “Shelf Takedown Request”).

(ii) With respect to a Shelf Takedown, the Company shall commence the Shelf Takedown and prepare and file with the SEC, as soon as practicable after the date on which it received the Shelf Takedown Request, any amendments or supplements to the applicable Resale Shelf S-3 to enable the Registrable Shares included in the Shelf Takedown to be offered and sold.

(e) Selection of Underwriters. The offering of Registrable Shares pursuant to such Underwritten Registration or Shelf Takedown, including pursuant to a Shelf Registration, shall be in the form of a “firm commitment” underwritten offering. The Demanding Stockholders making such Demand Request or Shelf Takedown Request shall select (i) the investment banking firm or firms to manage the underwritten offering and (ii) counsel to the Requesting Holders; provided that, in the case of clause (i), such selection shall be subject to the consent of the Company, which consent shall not be unreasonably withheld or delayed. No Holder may participate in any Underwritten Registration or Shelf Takedown pursuant to Section 2.2(a) unless such Holder (x) agrees to sell such Holder’s Registrable Shares on the basis provided in any underwriting agreement agreed upon by the Company and accepts the underwriters selected in accordance with the procedures described in this Section 2.2(e), and (y) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting agreement; provided that no such Holder shall be required to make any representations or warranties in connection with any such registration other than representations and warranties as to (i) such Holder’s ownership of his, her or its Registrable Shares to be transferred free and clear of all liens, claims, and encumbrances created by such Holder, (ii) such Holder’s power and authority to effect such transfer, and (iii) such matters pertaining to such Holder’s compliance with securities laws with respect to the Registrable Shares as may be reasonably requested; provided, further that any obligation of such Holder to indemnify any Person pursuant to any such underwriting agreement shall be several, not joint and several, among such Holders selling Registrable Shares, and such liability shall be limited to the net amount received by such Holder from the sale of his, her or its Registrable Shares pursuant to such Underwritten Registration or Shelf Takedown (which amounts shall include the amount of cash or the fair market value of any assets, including Common Stock, received in exchange for the sale or exchange of such Registrable Shares or that are the subject of a distribution), and the relative liability of each such Holder shall be in proportion to such net amounts; provided, further that this Section 2.2(e) shall not require any Holder of Registrable Shares to agree to any lock up agreement, market standoff agreement or holdback agreement other than those permitted by Section 2.5 hereof.

(f) Rights of Nonrequesting Holders. Upon receipt of any Demand Request or Shelf Takedown Request, the Company shall promptly (but in any event within five (5) days, or two (2) days in the case of a Shelf Registration or Shelf Takedown that is a bought or overnight offering) give written notice of such proposed Underwritten Registration or Shelf Takedown to all other Holders of Registrable Shares, if any, who shall have the right, exercisable by written notice to the Company within five (5) days (or two (2) days in the case of a Shelf Registration or Shelf Takedown that is a bought or overnight offering) of their receipt of the Company’s notice, to elect to include in such Underwritten Registration or Shelf Takedown such portion of their Registrable Shares as they may request, so long as such Registrable Shares are proposed to be disposed of in accordance with the method or methods of disposition requested pursuant to this Section 2.2. All Holders requesting to have their Registrable Shares included in an Underwritten Registration or Shelf Takedown in accordance with the preceding sentence together with all Demanding Stockholders shall be deemed to be “Requesting Holders” for purposes herein.

(g) Priority. No securities to be sold for the account of any Person (including the Company), other than a Requesting Holder, shall be included in an Underwritten Registration or Shelf Takedown if the managing underwriters shall advise the Company and the Requesting Holders in writing that the aggregate amount of such securities requested to be included in any such Underwritten Registration or Shelf Takedown would have an Adverse Effect. Furthermore, if the managing underwriters shall advise the Company and the Requesting Holders that, even after exclusion of all securities of other Persons pursuant to the immediately preceding sentence, the amount of Registrable Shares proposed to be included in such Underwritten Registration or Shelf Takedown by Requesting Holders is sufficiently large to cause an Adverse Effect, the Registrable Shares of the Requesting Holders to be included in such Underwritten Registration or Shelf Takedown shall equal the number of shares which the Requesting Holders are so advised can be sold in such offering without an Adverse Effect and such shares shall be allocated pro rata among the Requesting Holders on the basis of the number of Registrable Shares requested to be included in such registration by each such Requesting Holder; provided, that if the number of Registrable Shares owned by the Demanding Stockholder to be included in the Underwritten Registration or Shelf Takedown, as the case may be, is less than 80% of the number requested to be so included by such Demanding Stockholder, the Demanding Stockholder may withdraw such Demand Request or Shelf Takedown Request, as the case may be, by giving notice to the Company; if withdrawn, the Demand Request or Shelf Takedown Request, as the case may be, shall be deemed not to have been made for all purposes of this Agreement and the Company shall pay all expenses of such withdrawn Underwritten Registration or Shelf Takedown, as the case may be, in accordance with Section 2.8 hereof. An Underwritten Registration or Shelf Takedown shall not count as an Underwritten Registration or Shelf Takedown until the Registration Statement in connection with such offering has become effective or the related underwritten public offering has commenced, respectively, and any Underwritten Registration or Shelf Takedown, as the case may be, shall not count as an Underwritten Registration or Shelf Takedown unless the Demanding Stockholder is able to register and sell at least 80% of the Registrable Shares requested to be included by such Demanding Stockholder in such Underwritten Registration or Shelf Takedown, as the case may be.

(h) Deferral of Filing. The Company may defer the filing (but not the preparation) of a Registration Statement required by this Section 2.2 until after the Required Filing Date (i) for a period not to exceed sixty (60) days, if, at the time the Company receives the Demand Request, there exists a Material Disclosure Event, or (ii) for a period not to exceed sixty (60) days, if at the time the Company receives the Demand Request, the Board determines in its reasonable judgment that such Underwritten Registration would (A) materially interfere with a material acquisition, corporate organization, financing, securities offering or other similar transaction involving the Company or (B) render the Company unable to comply with requirements under the Securities Act or Exchange Act. A deferral of the filing of a Registration Statement pursuant to this Section 2.2(h) shall be lifted, and the requested Registration Statement shall be filed forthwith, if, in the case of a deferral pursuant to clause (i) of the preceding sentence, the Material Disclosure Event is disclosed or terminated, or, in the case of a deferral pursuant to clause (ii)(A) of the preceding sentence, the acquisition, corporate organization, financing, securities offering or similar transaction is abandoned, or, in the cause of a deferral pursuant to clause (ii)(B) of the preceding sentence, such Underwritten Registration would no longer render the Company unable to comply with the requirements under the Securities Act or the Exchange Act. In order to defer the filing of a Registration Statement pursuant to this Section 2.2(h), the Company shall promptly (but in any event within ten (10) days), upon

determining to seek such deferral, deliver to each Requesting Holder a certificate signed by an executive officer of the Company stating that the Company is deferring such filing pursuant to this Section 2.2(h), a general statement of the reason for such deferral and an approximation of the anticipated delay. Within twenty (20) days after receiving such certificate, the Demanding Stockholder may withdraw such Demand Request by giving notice to the Company; if withdrawn, the Demand Request shall be deemed not to have been made for all purposes of this Agreement and the Company shall pay all expenses of such withdrawn Underwritten Registration in accordance with Section 2.8 hereof. The Company may defer the filing of a particular Registration Statement pursuant to this Section 2.2(h) only on two occasions in any consecutive twelve (12)-month period; provided that any deferral pursuant to this Section 2.2(h) shall be deemed to be a “Suspension Period” for purposes of Section 2.7 and shall be subject to the limitations and obligations during Suspension Periods set forth in Section 2.7. Each Holder agrees to keep confidential the fact that the Company has exercised its rights under this Section 2.2(h) and all facts and circumstances relating to such exercise until such information is made public by the Company.

(i) Withdrawal and Cancellation. Any Requesting Holder may withdraw its Registrable Shares from an Underwritten Registration or Shelf Takedown at any time prior to the effectiveness of the related Registration Statement or the commencement of the related underwritten public offering, respectively, and any Demanding Stockholder shall have the right to cancel a proposed Underwritten Registration or Shelf Takedown of Registrable Shares pursuant to this Section 2.2(i). Upon such cancellation, the Company shall cease all efforts to secure registration and such Underwritten Registration or Shelf Takedown, as the case may be, shall not be counted as an Underwritten Registration or Shelf Takedown, as the case may be, under this Agreement for any purpose so long as the Demanding Stockholder pays all expenses (including the expenses of the Company) of such cancelled Underwritten Registration or Shelf Takedown, as the case may be.

Section 2.3 Piggyback Registrations

(a) Right to Piggyback. Each time the Company proposes to register any shares of Common Stock (other than pursuant to Section 2.2 or pursuant to an Excluded Registration) for sale to the public (whether for the account of the Company or the account of any security holder of the Company) (a “Piggyback Registration”), the Company shall give prompt written notice to each Holder of Registrable Shares not less than fifteen (15) days prior to the anticipated filing date of the Company’s registration statement. Such notice shall offer each such Holder the opportunity to include any or all of its Registrable Shares in such registration statement, subject to the limitations contained in Section 2.3(b) hereof. Each Holder who desires to have its Registrable Shares included in such registration statement shall so advise the Company in writing (stating the number of shares desired to be registered) within fifteen (15) days after the receipt of such notice from the Company. In the event the registration statement is not declared effective within ninety (90) days following the initial filing of such registration statement, unless a road show for an underwritten offering pursuant to such registration statement is actually in progress at such time, the Company shall promptly provide a new written notice to all Holders of Registrable Shares giving them another opportunity to elect to include Registrable Shares in the pending registration statement. Each Holder receiving such new written notice shall have the same rights afforded above. Subject to Section 2.3(b) below, the

Company shall include in such registration statement all such Registrable Shares so requested to be included therein; provided that the Company may at any time withdraw or cease proceeding with any such registration if it shall at the same time withdraw or cease proceeding with the registration of all other equity securities originally proposed to be registered and shall provide each Requesting Holder with prompt written notice of such withdrawal or cessation; provided, further that any Holder shall have the right to withdraw such Holder’s request for inclusion of such Holder’s Registrable Shares in any registration statement pursuant to this Section 2.3(a) by giving written notice to the Company of such withdrawal at least fifteen (15) days prior to such registration statement becoming effective.

(b) Priority on Piggyback Registrations.

(i) If a Piggyback Registration is an underwritten offering and was initiated by the Company, and if the managing underwriters advise the Company that the inclusion of Registrable Shares or other securities requested to be included in the registration statement would cause an Adverse Effect, then the Company shall be required to include in such registration statement, to the extent of the amount of securities that the managing underwriters advise may be sold without causing such Adverse Effect, (A) first, the securities the Company proposes to sell; (B) second, the Registrable Shares requested to be included in such registration by any Holder thereof together with any other securities requested to be included by any other holders of piggyback registration rights in such registration, pro rata among such Holders and such other holder of piggyback registration rights on the basis of the number of Registrable Shares and such other securities requested to be registered by each such Holder or each such other holder of piggyback registration rights; and (C) third, any other securities requested to be included in such registration. If, as a result of the provisions of this Section 2.3(b)(i), any Holder shall not be entitled to include all Registrable Shares in a registration that such Holder has requested to be so included, such Holder may withdraw such Holder’s request to include Registrable Shares in such registration statement.

(ii) If a Piggyback Registration is an underwritten offering and was initiated by any of the other security holders of the Company (other than as set forth in Section 2.2) (the “Secondary Offering Securityholders”), and if the managing underwriters advise the Company that the inclusion of Registrable Shares and securities held by the Secondary Offering Securityholders and any other holders of piggyback registration rights requested to be included in the Registration Statement would cause an Adverse Effect, the Company shall include in such registration statement, to the extent of the amount of securities that the managing underwriters advise may be sold without causing such Adverse Effect, (A) first, the other securities requested to be included by the Secondary Offering Securityholders, pro rata among such Secondary Offering Securityholders on the basis of the number of such other securities requested to be registered by each such Secondary Offering Securityholder; (B) second, the Registrable Shares requested to be included in such registration by any Holder thereof together with any other securities requested to be included by any other holders of piggyback registration rights in such registration, pro rata among such Holders and such other holders of piggyback registration rights on the basis of the number of Registrable Shares and such other securities requested to be registered by each such Holder and each such other holder of piggyback registration rights; and (C) third, any other securities requested to be included in such registration (including securities to be sold for the account of the Company). If, as a result of the provisions of this Section 2.3(b)(ii), any Holder shall not be entitled to include all Registrable Shares in a registration that such Holder has requested to be so included, such Holder may withdraw such Holder’s request to include Registrable Shares in such registration statement.

(iii) Notwithstanding any of the foregoing, the provisions of Sections 2.3(b)(i) and (ii) shall not apply to a Piggyback Registration that is a Shelf Registration.

(iv) No Holder may participate in any registration statement in respect of a Piggyback Registration hereunder unless such Holder (x) agrees to sell such Holder’s Registrable Shares on the basis provided in any underwriting agreement approved by the Company and (y) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting agreements; provided that no such Holder shall be required to make any representations or warranties in connection with any such registration other than representations and warranties as to (i) such Holder’s ownership of his, her or its Registrable Shares to be transferred free and clear of all liens, claims, and encumbrances created by such Holder, (ii) such Holder’s power and authority to effect such transfer, and (iii) such matters pertaining to such Holder’s compliance with securities laws with respect to the Registrable Shares as may be reasonably requested; provided, further that any obligation of such Holder to indemnify any Person pursuant to any such underwriting agreements shall be several, not joint and several, among such Holders selling Registrable Shares, and such liability shall be limited to the net amount received by such Holder from the sale of his, her or its Registrable Shares pursuant to such Piggyback Registration (which amounts shall include the amount of cash or the fair market value of any assets, including Common Stock, received in exchange for the sale or exchange of such Registrable Shares or that are the subject of a distribution), and the relative liability of each such Holder shall be in proportion to such net amounts; provided, further that this Section 2.3(b)(iv) shall not require any Holder of Registrable Shares to agree to any lock up agreement, market standoff agreement or holdback agreement other than those permitted by Section 2.5 hereof.

(c) Selection of Underwriters and Counsel. Subject to Section 2.1(c), if any Piggyback Registration is an underwritten offering initiated by the Company or another security holder of the Company, the Company or such other securityholder shall select an investment banking firm or firms to manage the offering. The Holders of a majority of the Registrable Shares included in any Piggyback Registration shall have the right to select one (1) counsel for such Holders.

(d) Effect on Demand Registrations. No registration of the Registrable Shares effected under this Section 2.3 shall relieve the Company of its obligation to effect a registration of Registrable Shares pursuant to Section 2.1 or Section 2.2.

Section 2.4 SEC Registration Statements. All Registration Statements shall comply with applicable requirements of the Securities Act, and, together with each prospectus included, filed or otherwise furnished by the Company in connection therewith, shall not contain any untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

Section 2.5 Holdback Agreements.

(a) The Company agrees (i) not to effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, except pursuant to the Resale Shelf S-3, any Additional Registration Statement, a Piggyback Registration that is not an underwritten offering and Excluded Registrations, during the seven (7) days prior to the effective date of any Registration Statement and thereafter until the date on which all of the Registrable Shares subject to such Registration Statement have been sold (not to exceed ninety (90) days, as required by the underwriters managing the offering) and (ii) if requested by the managing underwriters, to use reasonable efforts to cause each director and executive officer to agree not to effect any public sale or distribution (including sales pursuant to Rule 144) of any such securities during such period (except as part of an Underwritten Registration, if otherwise permitted); provided that the foregoing described holdback shall not apply to the extent that the managing underwriters of such offering otherwise agree or, in the event a Registration Statement does not relate to an Underwritten Registration with respect to clause (i), if the holders of a majority of such Registrable Shares consent thereto.

(b) If any Holders of Registrable Shares notify the Company in writing that they intend to effect an Underwritten Registration registered pursuant to a Shelf Registration or a Shelf Takedown, the Company agrees (i) not to effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for its equity securities, except pursuant to Excluded Registrations, during the seven (7) days prior to and during the ninety (90)-day period beginning on the filing of the prospectus supplement with respect to such offering (not to exceed ninety (90) days, as required by the underwriters managing the offering); and (ii) if requested by the managing underwriters, to use reasonable efforts to cause each director and executive officer to agree not to effect any public sale or distribution (including sales pursuant to Rule 144) of any such securities during such period (except as part of such Underwritten Registration, if otherwise permitted); provided that the foregoing described holdback shall not apply to the extent that the managing underwriters of such offering otherwise agree.

(g) otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the SEC, including the Securities Act and the Exchange Act, and make generally available to the Company’s security holders an earnings statement satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder, as soon as reasonably practicable, but no later than thirty (30) days after the end of the twelve (12)-month period beginning with the first day of the Company’s first fiscal quarter commencing after the effective date of a Registration Statement, which earnings statement shall cover said twelve (12)-month period; provided that such requirement shall be deemed satisfied if the Company timely files complete and accurate information on Forms 10-Q, 10-K and 8-K under the Exchange Act as required thereby and otherwise complies with Rule 158 under the Securities Act;

The selling Holders shall be parties to any such underwriting agreement, and the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of such selling Holders;

(q) make every reasonable effort to prevent the entry of any order suspending the effectiveness of the Registration Statement and, in the event of the issuance of any such stop order, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any security included in such Registration Statement for sale in any jurisdiction, the Company shall use commercially reasonable efforts promptly to obtain the withdrawal of such order;

Section 2.7 Suspension of Dispositions. Each Holder agrees by acquisition of any Registrable Shares that, upon receipt of any notice (a “Suspension Notice”) from the Company of the happening of any Material Disclosure Event, such Holder shall promptly discontinue such Holder’s disposition of Registrable Shares pursuant to a Registration Statement covering such Registrable Shares until such Holder’s receipt of the copies of the supplemented or amended prospectus in connection with such Registration Statement, or until it is advised in writing by the Company (the “Advice”) that the use of the prospectus in connection with such Registration Statement may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the prospectus in connection with such Registration Statement, and, if so directed by the Company, such Holder shall deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the prospectus covering such Registrable Shares current at the time of receipt of such notice. In the event the Company shall give any Suspension Notice, the applicable Effectiveness Period relating to the disposition of such Registrable Shares shall be extended by the number of days during the period from and including the date of the giving of the Suspension Notice to and including the date

when each seller of Registrable Shares covered by such Registration Statement shall have received the copies of the supplemented or amended prospectus or the Advice (such period, a “Suspension Period”). The Company shall use commercially reasonable efforts and take such actions as are reasonably necessary to render the Advice as promptly as practicable and shall as promptly as practicable after the expiration of the Suspension Period prepare a post-effective amendment or supplement to the Registration Statement or the prospectus thereto or any document incorporated therein by reference, or file any required document so that, as thereafter delivered to purchasers of the Registrable Shares included therein, the prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Notwithstanding anything herein to the contrary, the Company shall not be entitled to more than two (2) Suspension Periods during any consecutive twelve (12)-month period, which Suspension Periods shall have durations of not more than one hundred twenty (120) days in the aggregate; provided that a Suspension Period shall automatically expire upon the public disclosure of the information to which the Material Disclosure Event relates. Notwithstanding anything to the contrary in this Agreement, each Holder shall be entitled by delivery of written notice to the Company (an “Opt-Out Notice”) to elect to forego its rights to resell any Registrable Securities using the Registration Statement, and following the delivery of any such Opt-Out Notice, until the applicable Holder delivers to the Company a written notice electing to continue its use of the Registration Statement, (A) such Holder shall cease the sale of any Registrable Securities pursuant to the Registration Statement and (B) the Company shall not deliver to such Holder any notice of a Suspension Notice pursuant to this Section 2.7.

(b) In connection with any Registration Statement or prospectus in which a seller of Registrable Shares is participating pursuant to this Article 2, each such seller shall furnish to the Company such written information and affidavits regarding such seller, the Registrable Shares and the intended distribution thereof as the Company reasonably requests for use in connection with any such Registration Statement or prospectus and as shall be reasonably required in connection with any registration, qualification or compliance required in connection with this Article 2 and, to the fullest extent permitted by applicable law, each such seller shall indemnify the Company, and its officers and directors and each other Person who controls the Company (within the meaning of the Securities Act or the Exchange Act) and any of its or their respective officers, directors, employees, agents, representatives, successors, members, stockholders and partners (the “Company Covered Persons”) against any and all losses, claims, damages, liabilities and expenses, joint or several (including reasonable attorneys’ fees and disbursements, other than to the extent limited by Section 2.9(c) and (d)), (x) based upon, arising out of, related to or resulting from any untrue or alleged untrue statement of a material fact contained in any Registration Statement or any amendment thereto, or any document incorporated by reference therein, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and (y) based upon, arising out of, related to or resulting from any untrue or alleged untrue statement of a material fact contained in any prospectus, preliminary prospectus, Disclosure Package or Issuer Free Writing Prospectus or any amendment or supplement thereto, or any document incorporated by reference therein, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, but, in the case of either (x) or (y), only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission is contained in any written information furnished by such seller or any Holder Covered Person specifically stating that it has been provided for inclusion in such Registration Statement, prospectus, preliminary prospectus, Disclosure Package or Issuer Free Writing Prospectus or amendment or supplement thereto, or document incorporated by reference therein; provided that the obligation to indemnify shall be several, not joint and several, among such sellers of Registrable Shares, and the liability of each such seller of Registrable Shares shall be in proportion to, and shall be limited to, the net amount of proceeds received by such seller from the sale of Registrable Shares pursuant to such Registration Statement.

(c) 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 the failure to give such notice shall not limit the rights of such Person or relieve the indemnifying party from any liability that it may have under subsection (a) and (b) above unless and only to the extent that failure to give such notice materially prejudices the indemnifying party; and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and any indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any Person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim at the expense of such indemnified person, unless (x) the indemnifying party has agreed to pay such fees or expenses or (y) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person. If such defense is not assumed by the indemnifying party when permitted hereunder, the indemnified party shall be entitled to assume and control such defense and to settle and agree to pay in full such claim without the consent of the indemnifying party without prejudice to the ability of the indemnified party to enforce its claim for indemnification against the indemnifying party hereunder.

(d) Except as otherwise provided in the preceding paragraph, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent, which consent shall not be unreasonably withheld or delayed. If such defense is assumed by the indemnifying party pursuant to the provisions hereof, such indemnifying party shall not settle or otherwise compromise the applicable claim (i) unless (A) such settlement or compromise contains a full and unconditional release of the indemnified party and (B) such settlement or compromise does not include any statement as to, or any admission of, fault, culpability or a failure to act by or on behalf of the indemnified party or (ii) if such settlement or compromise provides for injunctive or other non-monetary relief, in each case, unless the indemnified party otherwise consents in writing. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one (1) counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party, a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the reasonable fees and disbursements of such additional counsel or counsels.

(e) Each party hereto agrees that, if for any reason the indemnification provisions contemplated by Section 2.9(a) or Section 2.9(b) are unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses (or actions in respect thereof) (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party and the indemnified party from the offering of Registrable Shares (taking into account the portion of the proceeds of the offering realized by each such party), or (ii) if the allocation provided by clause (i) is not permitted by applicable law, or provides a lesser sum to the indemnified party than the amount hereinafter calculated in this clause (ii), in such proportion as is appropriate not only to reflect the relative benefits referred to in clause (i), but also the relative fault of the indemnifying party and the indemnified party, respectively, in connection with the actions or omissions that resulted in the losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact 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 statement or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.9(e) were determined by pro rata allocation (even if the Holders or any underwriters or all of them were treated as one (1) entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 2.9(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to above shall be deemed to include (subject to any limitation set forth thereon) any legal or other fees or

expenses reasonably incurred by such indemnified party in connection with investigating or, except as provided in Section 2.9(c) and (d), defending any such action, proceeding or claim. Notwithstanding the provisions of this Section 2.9(e), no Holder shall be required to contribute an amount greater than the dollar amount by which the net proceeds received by such Holder with respect to the sale of any Registrable Shares exceeds the amount of damages that such Holder has otherwise been required to pay by reason of any and all untrue or alleged untrue statements of material fact or omissions or alleged omissions of material fact made in any Registration Statement, prospectus or preliminary prospectus or any amendment or supplement thereto, or any document incorporated by reference therein, related to such sale of Registrable Shares. 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 Holders’ obligations in this Section 2.9(e) to contribute shall be several in proportion to the amount of Registrable Shares registered by them and not joint and several. If indemnification is available under this Section 2.9, the indemnifying parties shall indemnify each indemnified party to the fullest extent provided in Section 2.9(a) and Section 2.9(b) without regard to the relative fault of said indemnifying party or indemnified party or any other equitable consideration provided for in this Section 2.9(e) subject, in the case of the Holders, to the limits set forth in Section 2.9(b).

(f) The indemnification and contribution provided for under this Agreement shall 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 shall survive the transfer of securities and the termination of this Agreement. The provisions of this Section 2.9 shall be in addition to any other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise.

(g) As used in this Section 2.9, the terms “officers” and “directors” shall include the direct or indirect partners, members or managers of Holders of Registrable Shares that are partnerships or limited liability companies, as the case may be.

Section 2.10 Transfer of Registration Rights. Provided that the Company is given prompt written notice by the Holder of Registrable Shares of any transfer of Registrable Shares by such Holder of Registrable Shares stating the name and address of the transferee of such Registrable Shares and identifying the securities with respect to which the rights under this Article 2 are being assigned, the rights of such Holder of Registrable Shares under this Article 2 may be transferred in whole or in part at any time to any such transferee, so long as such transfer of securities is in accordance with all applicable state and federal securities laws and regulations, with this Agreement and the provisions of any other instruments executed by and among each of the parties hereto, and such transferee agrees in writing to be bound by the terms of this Agreement by executing and delivering a Joinder Agreement in the form of Exhibit A hereto (the “Joinder Agreement”). The Company shall be responsible for the expenses of registration in accordance with Section 2.8 of any transferee or assignee pursuant to this Section 2.10 to the same extent as the original transferor, and the Company will cooperate with the applicable Holder to register the applicable Registrable Shares in such denominations and such names as such transferring Holder may request.

Section 2.11 Rule 144. The Company shall timely file (taking into account all valid extensions) the reports required to be filed by it under the Securities Act and the Exchange Act (or, if the Company is not required to file such reports, shall, upon the request of the Holders, make publicly available information substantially similar to the type of information that would be required if the Company was subject to rules under the Securities Act and the Exchange Act) and shall use commercially reasonable efforts to take such further action as the Holders may reasonably request (including the removal of the Transfer Legend or any applicable other Securities Act transfer restrictions or notations), in each case to the extent required from time to time to enable the Holders to sell Common Stock without registration under the Securities Act within the limitation of the exemptions provided by Rule 144. Upon the reasonable request of any Holder, the Company shall deliver to such parties a written statement as to whether it has complied with such requirements, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as may be reasonably requested by any Holder in availing itself of any rule or regulation of the SEC permitting the selling of any the securities without registration and shall, at its expense, forthwith upon the request of any such Holder, deliver to such Holder a certificate, signed by the Company’s principal financial officer, stating (a) the Company’s name, address and telephone number (including area code), (b) the Company’s Internal Revenue Service identification number, (c) the Company’s SEC file number, (d) the number of shares of each class of capital stock outstanding as shown by the most recent report or statement published by the Company, and (e) whether the Company has filed the reports required to be filed under the Exchange Act for a period of at least ninety (90) days prior to the date of such certificate and has filed the most recent annual report required to be filed thereunder.

Section 2.12 Listing. So long as any Registrable Securities are outstanding, the Company shall use its commercially reasonable efforts to maintain the approval of the Common Stock for listing on the New York Stock Exchange or such other exchange or trading market as the Common Stock is then listed.

Section 2.13 Preservation of Rights.

(a) Notwithstanding anything herein to the contrary, the Company represents and warrants that the registration rights contemplated hereby are not more favorable in any material respect than or otherwise inconsistent with the respective registration rights granted to the respective “Holders” under the Company’s Registration Rights Agreements dated August 31, 2012 and July 14, 2016, and, except as otherwise provided for herein, such “Holders” shall be treated pari passu or with priority with respect to the Holders hereunder and have priority over the Holders hereunder.

(b) From and after the date of this Agreement, the Company shall not (a) enter into any agreement with any Holder or prospective holder of any securities of the Company providing for the granting to such Holder or prospective holder of registration rights that are more favorable in any material respect than or are otherwise inconsistent with the rights granted hereunder and which does not expressly provide that the Holders in this Agreement shall be treated pari passu or with priority with respect to such Holders and prospective holders and have priority over such prospective holders of securities of the Company in any subsequent registration statement or (b) with respect to its securities, enter into any agreement or

arrangement, take any action, or permit any change to occur that violates or subordinates the rights expressly granted to the Holders in this Agreement. Notwithstanding anything herein to the contrary, the Company further agrees that if any other registration rights agreement entered into after the date of this Agreement with respect to any of its securities contains terms which are more favorable to, or less restrictive on, the other party thereto than the terms and conditions contained in this Agreement are (insofar as they are applicable) to the holders of Registrable Shares, then the terms and conditions of this Agreement shall immediately be deemed to have been amended without further action by the Company or any of the holders of Registrable Shares so that such holders shall each be entitled to the benefit of any such more favorable or less restrictive terms or conditions.

Section 2.14 Applicability of Rights to Holders in the Event of an Acquisition. In the event the Company merges into, consolidates with, sells substantially all of its assets to or otherwise becomes an Affiliate of a Person pursuant to a transaction or series of related transactions in which Holders or the respective members, partners or stockholders, as applicable, of the Holders receive equity securities of such Person (or of any Affiliate of such Person) in exchange for shares of Common Stock held by such Holders, all of the rights of the Holders set forth in this Agreement shall continue in full force and effect and shall apply to the Person the equity securities of which are received by such Holders pursuant to such transaction or series of related transactions. The Company agrees that the Company shall not enter into any agreement that has the effect set forth in the first clause of the preceding sentence unless such Person agrees to be bound by the foregoing provision.

Section 2.15 Deemed Underwriters. To the extent that, in connection with a registration of any of the Registrable Shares under the Securities Act pursuant to Section 2.1, any selling Holder is deemed to be an underwriter of Registrable Shares pursuant to any SEC comments or policies, the Company agrees that (1) the indemnification and contribution provisions contained in Section 2.9 shall be applicable to the benefit of such selling Holder in its role as deemed underwriter in addition to its capacity as Holder and (2) such selling Holder shall be entitled to conduct the due diligence which it would normally conduct in connection with an offering of securities registered under the Securities Act, including receipt of customary opinions and comfort letters.

Section 2.16 Cooperation by Holders. Each selling Holder agrees to furnish to the Company a completed questionnaire (a “Selling Securityholder Questionnaire”) not later than three (3) Business Days following the date on which such Holder receives the form of Selling Securityholder Questionnaire with respect to any Registration Statement. A Holder shall provide to the Company all such information, including information regarding such Holder and the distribution proposed by such Holder, and all such materials, including a Selling Securityholder Questionnaire and updates thereto, as may be requested, and take all such action, in each case as may be required or reasonably requested in order to permit the Company to comply with all applicable requirements of the Securities Act, the Exchange Act and any applicable regulatory or self-regulatory authority and the obligations and requirements of this Agreement, such provision of information and materials to be a condition precedent to the obligations of the Company pursuant to this Agreement to register the Registrable Shares held by such Holder. The Company shall have no obligation to file a Registration Statement if a Holder has failed to timely furnish, after receipt of a written request from the Company, such information that the Company determines, after consultation with its counsel, is reasonably required in order for the registration statement to comply with the Securities Act until such information has been furnished.

ARTICLE 3

TERMINATION

Section 3.1 Termination. A particular Registrable Share shall cease to be a Registrable Share on the earlier of: (a) a registration statement covering such Registrable Share has been declared effective under the Securities Act by the SEC and such Registrable Share has been disposed of pursuant to such effective registration statement; (b) such Registrable Share is sold to the public pursuant to Rule 144; or (c) such Registrable Share ceases to be outstanding. This Agreement shall terminate automatically on the date on which the Holders, together with their Affiliates, beneficially own (as contemplated by Rule 13d-3 of the Exchange Act) less than 1,000,000 Registrable Shares. This Agreement may be terminated at any time by the written agreement of holders of at least a majority of all Registrable Shares then outstanding.

ARTICLE 4

MISCELLANEOUS

Section 4.1 Whole Agreement. This Agreement, together with the other Transaction Documents, constitute the entire agreement among the parties hereto and thereto with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter hereof and thereof (other than the non-disclosure and confidentiality agreements, if any, between the Company and the Holders signed in anticipation of an equity financing in the Company); provided, that in the event of any conflict or ambiguity between the terms of the Purchase Agreement and the terms of this Agreement, the terms of this Agreement shall control.

Section 4.2 Successors and Assigns. Except as otherwise provided herein, no party hereto may assign, directly or indirectly, by operation of law or otherwise, any of its respective rights or delegate any of its responsibilities, liabilities or obligations under this Agreement, without the prior written consent of each other party hereto.

Section 4.3 Amendment and Waiver. Except as otherwise provided herein and other than as a result of the execution and delivery of a Joinder Agreement, no amendment, alteration or modification of this Agreement or waiver of any provision of this Agreement shall be effective against the Company or the Holders unless such amendment, alteration, modification or waiver is approved in writing by the Company and the Holders of a majority of the Registrable Shares; provided, however, that no amendment, alteration, modification or waiver of the rights of any Holder may be made without such Holder’s prior written consent if such amendment, alteration, modification or waiver would have an Adverse Effect on such Holder’s rights under this Agreement. The failure of any party to enforce any provision of this Agreement shall not be construed as a waiver of such provision and shall not affect the right of such party thereafter to enforce each provision of this Agreement in accordance with its terms.

Section 4.4 Severability. If any provision of this Agreement, including any phrase, sentence, clause, Section or subsection, is inoperative or unenforceable for any reason, such circumstances shall not have the effect of rendering the provision in question inoperative or unenforceable in any other case or circumstance, or of rendering any other provision or provisions herein contained invalid, inoperative, or unenforceable to any extent whatsoever. If any provision of this Agreement shall be adjudged to be excessively broad as to duration, geographical scope, activity or subject, the parties hereto intend that such provision shall be deemed modified to the minimum degree necessary to make such provision valid and enforceable under applicable law and that such modified provision shall thereafter be enforced to the fullest extent possible.

Section 4.5 Remedies. The Parties agree that money damages or another remedy at law would not be a sufficient or adequate remedy for any breach or violation of, or a default under, this Agreement by them and that, in addition to all other remedies available to them, each of them shall be entitled to an injunction restraining such breach, violation or default or threatened breach, violation or default and to any other equitable relief including specific performance without bond or other security being required.

Section 4.6 No Third Party Beneficiaries. Nothing in this Agreement, express or implied, is intended or shall be construed to give any person other than the Parties (including any permitted transferees that hereafter become Parties in accordance with Section 2.10) to this Agreement, or any of their respective successors and permitted assigns any legal or equitable right, remedy or claim under or in respect of any agreement or provision contained herein.

Section 4.7 Counterparts. This Agreement may be executed in several counterparts (including by facsimile, .pdf or other electronic transmission), each of which shall be deemed an original and all of which shall together constitute one and the same instrument.
