promptly as practicable and at least 30 days prior to such Determination Date, the Company shall (A) give written notice thereof to all of the Holders and (B) if the Company is S-3 Shelf Eligible, file a Registration Statement on Form S-3 with respect to a Shelf Registration in accordance with Section 2.2(a) and use its commercially reasonable efforts to have such Registration Statement declared effective prior to the Determination Date. If the Company has filed an existing Automatic Shelf Registration Statement that is effective, and it is likely that such existing Automatic Shelf Registration Statement will no longer be effective pursuant to SEC Guidance as of a Determination Date, although the Company will remain a Well-Known Seasoned Issuer as of such Determination Date, the Company will use commercially reasonable efforts to file a new Automatic Shelf Registration Statement to replace such existing Automatic Shelf Registration Statement prior to such Determination Date and cause such Automatic Shelf Registration Statement to remain effective thereafter until the date set forth in Section 2.7(a)(ii).

2.3                               Piggyback Registration Rights.

(a)                                 At any time the Company proposes to file a Registration Statement to register Common Stock under the Securities Act (other than pursuant to Section 2.1 or 2.2), or to conduct an Underwritten Offering from an existing Shelf Registration Statement, whether or not for its own account (other than pursuant to a Registration Statement on Form S-4 or Form S-8 or any similar or successor form under the Securities Act) or for the account of any person (other than a Holder pursuant to Section 2.1 or 2.2), the Company shall give written notice thereof to each Holder at least 10 Business Days before such filing or the commencement of such Underwritten Offering, as applicable, offering each Holder the opportunity to register on such Registration Statement or including in such Underwritten Offering, as applicable, such number of Registrable Securities as such Holder may request in writing not later than five Business Days after receiving such notice in writing from the Company (a “Piggyback Registration”). Upon receipt by the Company of any such request, the Company shall use its commercially reasonable efforts to, or in the case of an Underwritten Offering, use its commercially reasonable efforts to cause the Underwriters to, include such Registrable Securities in such Registration Statement (or in a separate Registration Statement concurrently filed) and to cause such Registration Statement to become effective with respect to such Registrable Securities.  If no request for inclusion from a Holder is received by the Company within the deadlines specified above, such Holder shall have no further right to participate in such Piggyback Registration. Notwithstanding the foregoing, if at any time after giving written notice of a registration in accordance with the first sentence of this paragraph (a) and before the effectiveness of the Registration Statement described in such notice, the Company determines for any reason either not to effect such registration or to delay such registration, the Company may, at its election, by delivery of written notice to each Holder exercising its rights to Piggyback Registration, (i) in the case of a determination not to effect registration, relieve itself of its obligation to effect a Piggyback Registration of the Registrable Securities in connection with such registration or (ii) in the case of a determination to delay registration, delay the Piggyback Registration of such Registrable Securities of the Holders for the same period as the delay in the registration of such other Registrable Securities; provided, that in the case of any such termination, withdrawal or delay, all expenses incurred in connection

14

with such Piggyback Registration shall be borne entirely by the Company as set forth in Section 2.9.  If any Holder requests inclusion in a registration pursuant to this Section 2.3, he, she, or it may, at any time before the effective date of the Registration Statement relating to such registration, revoke such request by delivering written notice of such revocation to the Company (which notice shall be effective only upon receipt by the Company, notwithstanding the provisions of Article II); provided, however, that if the Company, in consultation with its financial and legal advisors, determines that such revocation would materially delay the registration or otherwise require a recirculation of the prospectus contained in the Registration Statement, then such Holder shall have no right to so revoke his, her, or its request. The Company shall keep the Holder reasonably informed as to the status or expected timing of the launch of any Public Offering registered pursuant to any such Piggyback Registration.  No registration of Registrable Securities effected under this Section 2.3 shall relieve the Company of its obligations to effect any Demand Registration pursuant to Section 2.1 or Shelf Registration pursuant to Section 2.2.  The rights of Holders with respect to a Piggyback Registration shall be subject to Suspension Periods, as provided in Section 2.5.  To the extent an Underwritten Offering is made under any such Registration Statement, all Holders exercising their right to Piggyback Registration must sell their Registrable Securities to the Underwriters selected as provided in Section 2.7(f) on the same terms and conditions as apply to the other securityholders selling in such Underwritten Offering.

(b)                                 If a Piggyback Registration involves an Underwritten Offering (other than any Demand Registration, in which case the provisions with respect to priority of inclusion in such offering set forth in Section 2.1(c) shall apply or a Shelf Public Offering, in which case the provisions with respect to priority of inclusion in such offering set forth in Section 2.2(c) shall apply) and the managing Underwriter advises the Company that, in its view, the number of Registrable Securities that the Holders and the Common Stock that the Company intend to include in such Underwritten Offering exceeds the Maximum Offering Size, the Company shall include in such Underwritten Offering the following securities, in the following priority, up to the Maximum Offering Size:

(i)                                     first, all Common Stock that is requested to be included by the Company in the Underwritten Offering for its own account;

(ii)                                  second, Registrable Securities that are requested to be included in the Underwritten Offering pursuant to this Section 2.3 by any Holder on a pro rata basis on the basis of the requesting Holders’ beneficial ownership of the Common Stock; provided that to the extent a reduction in Registrable Securities included in the Underwritten Offering is so required, the calculation of the beneficial ownership of Registrable Securities shall not include any unvested Earn-out Shares and, for the avoidance of doubt, shall not include any Common Stock underlying the Preferred Stock prior to the date such Preferred Stock is convertible in accordance with the Certificate of Incorporation; and

15

(iii)                               third, all other securities that are requested to be included in the Underwritten Offering for the account of any other Persons with such priorities among them as the Company shall determine.

2.4                               Underwritten Offering.  Notwithstanding anything herein to the contrary, no Holder may participate in any Underwritten Offering hereunder unless such Holder accurately completes and executes in a timely manner all questionnaires, powers of attorney, indemnities, custody agreements, underwriting agreements (as approved in accordance with the terms of this Agreement), and other documents reasonably requested under the terms of such underwriting arrangements; provided, that all Persons participating in such Underwritten Offering shall be required to complete and execute, on the same terms and conditions, such questionnaires, powers of attorney, indemnities, custody agreements, underwriting agreements, and other documents (if applicable). The right of a Holder to register and sell Registrable Securities in an Underwritten Offering shall also be subject to any restrictions, limitations or prohibitions on the sale of Registrable Securities (subject to the limitations in Section 2.6) as may be required by the Underwriters in the interests of the offering (and, without limiting the foregoing, each Holder shall in connection therewith agree to be bound by (and if requested, execute and deliver) a lock-up agreement with the Underwriter(s) of any such Underwritten Offering as provided in Section 2.6).

2.5                               Suspension.  Notwithstanding anything to the contrary contained in this Article II, but subject to the limitations set forth in this Section 2.5, the Company shall be entitled to suspend its obligation to (a)  file or submit (but not to prepare) any Registration Statement in connection with any Demand Registration or Shelf Registration, (b) file or submit any amendment to such a Registration Statement, (c) file, submit or furnish any supplement or amendment to a prospectus included in such a Registration Statement, (d) make any other filing with the SEC, (e) cause such a Registration Statement or other filing with the SEC to become or remain effective or (f) take any similar actions or actions related thereto (including entering into agreements and actions related to the marketing of securities) (collectively, “Registration Actions”) upon (i) the issuance by the SEC of a stop order suspending the effectiveness of any such Registration Statement or the initiation of proceedings with respect to such a Registration Statement under Section 8(d) or 8(e) of the Securities Act, (ii) the Board of Directors’ determination, in its good faith judgment, that any such Registration Action should not be taken because it would reasonably be expected to materially interfere with or require the public disclosure of any material corporate development or plan, including any material financing, securities offering, acquisition, disposition, corporate reorganization or merger or other transaction involving the Company or any of its Subsidiaries or (iii) the Company possessing material non-public information the disclosure of which the Board of Directors determines, in its good faith judgment, would reasonably be expected to not be in the best interests of the Company. Upon the occurrence of any of the conditions described in clause (i), (ii) or (iii) above in connection with undertaking a Registration Action, the Company shall give prompt notice of such suspension (and whether such action is being taken pursuant to clause (i), (ii) or (iii) above) (a “Suspension Notice”) to the Holders.  Upon the termination of such condition, the Company shall give prompt

16

notice thereof to the Holders and shall promptly proceed with all Registration Actions that were suspended pursuant to this paragraph.  The Company may only suspend Registration Actions pursuant to clause (ii) or (iii) above on two occasions during any period of 12 consecutive months 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) during such 12 consecutive month period (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 Holders and shall be deemed to end on the earlier to occur of (x) the date on which the Company gives the Holders a notice that the Suspension Period has terminated and (y) the date on which the number of days during which a Suspension Period has been in effect exceeds the 90-day limit during such 12 consecutive month period.  If the filing of any Demand Registration or Shelf Registration is suspended pursuant to this Section 2.5, once the Suspension Period ends the Holders requesting such registration may request a new Demand Registration or Shelf Registration (and any such request for a Demand Registration shall not be counted as an additional Demand Registration for purposes of Section 2.1(a)).  Notwithstanding anything to the contrary in this Article II, the Company shall not be in breach of, or have failed to comply with, any obligation under this Article II where the Company acts or omits to take any action in order to comply with applicable Law, any SEC Guidance or any Order.  Each Holder shall keep confidential the fact that a Suspension Period is in effect unless otherwise notified by the Company, except (a) for disclosure to the Registration Participants or Holders, as applicable, and their employees, agents and professional advisers who reasonably need to know such information for purposes of assisting such Registration Participants or Holders with respect to its investment in the Common Stock and agree to keep it confidential, (b) for disclosures to the extent required in order to comply with reporting obligations to its limited partners or other direct or indirect investors who are subject to confidentiality arrangements with such Holder, (c) if and to the extent such matters are publicly disclosed by the Company or any of its Subsidiaries or any other Person that, to the actual knowledge of such Holder, was not subject to an obligation or duty of confidentiality to the Company and its Subsidiaries, (d) as required by applicable Law (provided, that the Holder gives prior written notice to the Company of such requirement and the contents of the proposed disclosure to the extent it is permitted to do so under applicable Law), and (e) for disclosure to any other Holder who is subject to the foregoing confidentiality requirement.

2.6                               Lockup Agreements.

(a)                                 Each Holder owning Registrable Securities representing beneficial ownership of 1% or more of the outstanding Common Stock (calculation of the beneficial ownership of Registrable Securities shall not include any unvested Earn-out Shares and, for the avoidance of doubt, shall not include any Common Stock underlying the Preferred Stock prior to the date such Preferred Stock is convertible in accordance with the Certificate of Incorporation) hereby agrees that, in connection with an Underwritten Offering, except for sales in such Underwritten Offering:

17

(i)                                     it will not effect any public sale or distribution (including sales pursuant to Rule 144 and pursuant to derivative transactions) of Common Stock (1) in connection with an Underwritten Offering that is being made pursuant to a Demand Registration Statement, a Shelf Registration Statement or a Piggyback Registration, in each case in accordance with this Article II, during (A) the period commencing on the seventh day prior to the expected time of circulation of a preliminary prospectus with respect to such Underwritten Offering (or, if no preliminary prospectus is circulated, the commencement of any marketing efforts with respect to such Underwritten Offering) and ending on the 90th day following the date of the final prospectus covering such Registrable Securities in connection with such Underwritten Offering or (B) such shorter period as the Underwriters with respect to such Underwritten Offering may require; provided, that the duration of the restrictions described in this clause (i) shall be no longer than the duration of the shortest restriction generally imposed by the Underwriters on the chief executive officer and the chief financial officer of the Company (or Persons in substantially equivalent positions) in connection with such Underwritten Offering; and

(ii)                                  it will 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.

(b)                                 In connection with an Underwritten Offering, except for sales in such Underwritten Offering, the Company (and its directors and officers) agrees that it:

(i)                                     shall not effect any public sale or distribution of Common Stock or securities convertible into or exercisable for Common Stock (except pursuant to registrations on Form S-8 or Form S-4 or any similar or successor form under the Securities Act) during (A) the period commencing on the seventh day prior to the expected time of circulation of a preliminary prospectus with respect to such Underwritten Offering (or, if no preliminary prospectus is circulated, the commencement of any marketing efforts with respect to such Underwritten Offering) and ending on the 90th day following the date of the final prospectus covering such Registrable Securities in connection with such Underwritten Offering or (B) such shorter period as the Underwriters with respect to such Underwritten Offering may require; and

(ii)                                  to the extent requested by the Underwriters participating in such Underwritten Offering, it shall agree to include provisions in the relevant underwriting or other similar agreement giving effect to the restrictions described in clause (i) above, in form and substance reasonably acceptable to such Underwriters.

2.7                               Registration Procedures.  Whenever the Holders of Registrable Securities have requested that any Registrable Securities be registered pursuant to this Agreement, subject to Section 2.5, the Company shall use its commercially reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance

18

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 practicable, prepare and file with the SEC a Registration Statement on the form required by the Section of this Article II under which such Registration Statement is required to be filed, which form shall be available, pursuant to SEC Guidance, 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, to the extent permitted by SEC Guidance, for a period of (i) not less than 180 days (or, if sooner, until all Registrable Securities have been sold under such Registration Statement), which duration shall not count any Suspension Period, or (ii) in the 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 S-3 Shelf Eligible.

(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 Holder, 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 Holder, 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 Holder or Underwriter may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Holder; 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 (other than as provided in the Agreement of which this Article II forms a part). In addition, the Company shall, as expeditiously as practicable, keep the Holders advised in writing as to the initiation and progress of any registration under Sections 2.1, 2.2 or 2.3 and provide each Holder with copies of all correspondence (including any comment letter) with the SEC or any other Governmental Authority in connection with any such Registration Statement.  Each Holder shall have the right to request that the Company modify any information contained in such Registration Statement, amendment and supplement thereto pertaining to such Holder, 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 such modification the Company reasonably expects that so doing would cause the relevant document to contain an untrue statement of a material fact

19

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 and other SEC Guidance 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 Holder thereof set forth in such Registration Statement or supplement to such prospectus and (iii) promptly notify each Holder holding Registrable Securities covered by such Registration Statement and the Holders’ Counsel any stop order issued or threatened by the SEC or any state securities commission with respect thereto and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered.

(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 Holder holding such Registrable Securities reasonably (in light of such Holder’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 Holder 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 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 Holder to consummate the disposition of the Registrable Securities owned by such Holder; provided, that the Company shall not be required to (1) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 2.7(d), (2) subject itself to taxation in any such jurisdiction or (3) consent to general service of process in any such jurisdiction.

(e)                                  The Company shall as promptly as practicable notify each Holder 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 include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements in light of the circumstances under which they were made not misleading and the Company shall promptly prepare and make available to each Holder and file with the SEC any such supplement or amendment, (ii) if the Company becomes aware of any request by the SEC or any other Governmental Authority for amendments or supplements to a Registration Statement or related prospectus covering Registrable Securities or for additional information relating thereto, (iii) if the Company becomes aware of the issuance or threatened issuance by the

20

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 Holders holding a majority of the Registrable Securities to be included in a Demand Registration or intended to be sold pursuant to a Shelf Public Offering pursuant to a “take down” under a Shelf Registration shall have the right to select Underwriters in connection with any Underwritten Offering resulting from the exercise of a Demand Registration or a Shelf Registration (which Underwriters may include any Affiliate of any Holder so long as including such Affiliate would not require that the separate engagement of a qualified 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 Underwriters in connection with any other Underwritten Offering. In connection with any Underwritten 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 Underwritten Offering, including, if required, the engagement of a “qualified independent underwriter” in connection with the qualification of the underwriting arrangements with FINRA.

(g)                                  Subject to confidentiality arrangements or agreements in form and substance reasonably satisfactory to the Board of Directors, the Company shall make available for inspection (upon reasonable notice and during normal business hours) by any Holder and any Underwriter participating in any disposition pursuant to a Registration Statement being filed by the Company pursuant to this Section 2.7 and any attorney, accountant or other professional retained by any such Holder 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 officers and the employees of the Company 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 SEC Guidance, Law or legal or administrative 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 other than as a result of a violation of this Section 2.7(g) or any other agreement or duty of confidentiality, (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 Holder agrees that information obtained by it as a result of such inspections shall be deemed confidential

21

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 Holder further agrees that, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, it shall, to the extent permitted by applicable Law, 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 Holder and to each Underwriter, if any, a signed counterpart, addressed to such 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 covering such matters of the kind customarily covered by opinions or comfort letters, as the case may be, any Holder or the managing Underwriter therefor reasonably requests.

(i)                                     The Company shall otherwise comply with all applicable SEC Guidance and make available to its security holders, as soon as reasonably practicable, 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 Holder 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 Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.7(e), such Holder shall forthwith discontinue disposition of Registrable Securities pursuant to the Registration Statement (including any Shelf Registration) covering such Registrable Securities until such Holder’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) above, if so directed by the Company, such Holder shall deliver to the Company (or otherwise destroy and promptly certify in writing to such destruction) all copies, other than any file copies then in such Holder’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 2.7(a)) by the number of days during the period from and including the date of the giving of notice pursuant to Section 2.7(e) to the date when the Company shall (x) make available to such Holder a prospectus supplemented or amended to conform with the requirements of Section 2.7(e) or (y) deliver to such Holder the notice described in clause (ii) above.

(l)                                     The Company shall use its commercially reasonable efforts to maintain the listing of all Registrable Securities of any class or series covered by such Registration Statement on NASDAQ or another U.S. national securities exchange.

22

(m)                             The Company shall have appropriate officers (i) upon reasonable request and at reasonable times prepare and make presentations at any “road shows” in connection with Underwritten Offerings and (ii) otherwise use their commercially reasonable efforts to cooperate as requested by the Underwriters in the offering, marketing or selling of the Registrable Securities.

(n)                                 The Company shall as soon as possible following its actual knowledge thereof, notify each Holder: (i) 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; (ii) of any request by the SEC or any other 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 (iii) 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 Holder 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 SEC Guidance, 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 Article II (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 Underwriters reasonably request (which information may be provided by means of a prospectus supplement if permitted by SEC Guidance).

2.8                               Holder Obligations.

(a)                                 If Registrable Securities owned by any Holder are included in a Demand Registration Statement, a Shelf Registration Statement or a Piggyback Registration, such Holder shall furnish promptly to the Company such information regarding itself and the distribution of such Registrable Securities by such Holder as is required under SEC Guidance or as the Company may otherwise from time to time reasonably request in writing.

23

(b)                                 Each Holder that has requested inclusion of its Registrable Securities in any Registration Statement shall (i) furnish to the Company (as a condition precedent to such Holder’s participation in such registration) in writing such information with respect to such Holder, its ownership of Common Stock and the intended method of disposition of its Registrable Securities as the Company may reasonably request or as may be required by SEC Guidance for use in connection with any related Registration Statement or prospectus (or amendment or supplement thereto) and any Free Writing Prospectus related thereto and all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not cause such Registration Statement, prospectus or Free Writing Prospectus (A) to fail to comply with SEC Guidance or (B) contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading and (ii) comply with SEC Guidance and all applicable state securities laws and comply with all applicable regulations in connection with the registration and the disposition of Registrable Securities.

(c)                                  Each Holder shall, as promptly as practicable, to the extent it is a Registration Participant in a Registration Statement, following its actual knowledge thereof, notify the Company of the occurrence of any event that would reasonably be expected to cause a Registration Statement or prospectus in which its Registrable Securities or any related Free Writing Prospectus are included, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading.

(d)                                 Each Holder shall use commercially reasonable efforts to cooperate with the Company in preparing the applicable Registration Statement to the extent it is a Registration Participant and any related prospectus or Free Writing Prospectus.

(e)                                  Each Holder agrees that no Holder shall be entitled to sell any Registrable Securities pursuant to a Registration Statement or to receive a prospectus relating thereto unless such Holder has complied with its obligations under this Article II.

2.9                               Registration Expenses.  In connection with the Company performing its obligations under this Article II, the Registration Expenses of all Registrations shall be borne by the Company, regardless of whether the Registration Statement becomes effective or such offering or other transaction is completed. It is acknowledged by the Holders that the Holders shall bear incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, in proportion to the number of Registrable Securities sold by each such selling Holder.

2.10                        Indemnification.

(a)                                 The Company agrees to indemnify, to the fullest extent permitted by law, each Holder holding Registrable Securities covered by a Registration Statement, its Affiliates, stockholders, employees, agents, officers, partners, members,

and directors, and each Person who controls such Holder (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) (collectively the “Holder Parties”), for whom Registrable Securities are to be registered pursuant to this Article II against all losses, claims, damages, liabilities, and expenses (including reasonable expenses of investigation and reasonable attorneys’, accountants’ and experts’ fees and expenses) (“Damages”) caused by or relating to (A) any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, or any documents incorporated by reference therein, or any Free Writing Prospectus utilized in connection therewith; (B) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (C) any untrue statement or alleged untrue statement of a material fact in the information conveyed to any purchaser at the time of the sale to such purchaser, or the omission or alleged omission to state therein a material fact required to be stated therein, and will reimburse each such Holder Party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Damages or in related actions or proceedings, except, in each case, insofar as the same are caused by or contained in any information regarding such holder furnished in writing to the Company by such holder expressly for use therein.  The Company also agrees to indemnify and hold harmless any Underwriters of the Registrable Securities (including any Holders who is deemed to be an Underwriter within the meaning of Section 2(a)(11) of the Securities Act), 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 Holders provided in this Section 2.10.

(b)                                 In connection with any Registration Statement in which a Holder for whom Registrable Securities are to be registered pursuant to this Article II is participating, each such Holder shall, to the fullest extent permitted by law, indemnify (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 Holder participating in any offering of Registrable Securities and (iv) the respective partners, Affiliates, stockholders, members, officers, directors, employees and agents of each of the Persons specified in clauses (i) through (v), from and against all Damages to the same extent as the foregoing indemnity from the Company resulting from or relating to (A) any untrue or alleged untrue statement of material fact contained in the Registration Statement, prospectus, or preliminary prospectus or any amendment thereof or supplement thereto or any Free Writing Prospectus utilized in connection therewith; (B) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (C) any untrue statement or alleged untrue statement of a material fact in the information conveyed to any purchaser at the time of the sale to such purchaser, or the omission or alleged omission to state therein a material fact required to be stated therein, but only to the extent, in each such case, that such untrue statement or alleged untrue statement or omission or alleged omission is contained in any information or affidavit regarding such holder so furnished in writing by such Holder expressly for use therein; provided, that the obligation to indemnify shall be individual, not joint and several, for each Holder and shall be limited

25

to the net amount of proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. As a condition to including Registrable Securities in any Registration Statement filed in accordance with this Article II, the Company may require that it shall have received an undertaking reasonably satisfactory to it from any Underwriter to indemnify and hold it harmless to the extent customarily provided by Underwriters with respect to similar securities and offerings.  No Holder shall be liable under this Section 2.10 for any Damages in excess of the net proceeds realized by such Holder in the sale of Registrable Securities of such Holder to which such Damages relate.

(c)                                  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 2.10(a) or 2.10(b), 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 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 or (ii) in the reasonable judgment of such Indemnified Party (A) representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (B) there would be rights or defenses that would be available to such Indemnified Party that are not 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 an 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 each Indemnified Party from and against any Damages (to the extent obligated herein) by reason of such settlement or judgment.  Without the prior written consent of each affected Indemnified Party, no Indemnifying Party shall effect any settlement of any pending or threatened proceeding in respect of which such 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.

(d)                                 If the indemnification provided for in Section 2.10(a) or Section 2.10(b) is held by a court of competent jurisdiction to be unavailable to the

26

Indemnified Parties or is insufficient in respect of any Damages, then each 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 the Indemnified Parties and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. The parties agree that it would not be just and equitable if contribution pursuant to this Section 2.10(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above.  The amount paid or payable by a party as a result of the Damages referred to above shall be deemed to include, subject to the limitations set forth in Section 2.10(a) or Section 2.10(b), 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 2.10, no Holder shall be required to contribute any amount in excess of the net proceeds (after deducting the Underwriters’ discounts and commissions) received by such Holder 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 Holder’s obligation to contribute pursuant to this Section 2.10 is several in the proportion that the proceeds of the offering received by such Holder bears to the total proceeds of the offering received by all such Holders and not joint.  The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, or controlling Person of such indemnified party and shall survive the transfer of securities.  The Company also agrees to make such provisions, as are reasonably requested by any indemnified party, for contribution to such party in the event the Company’s indemnification is unavailable for any reason.

2.11                        Rule 144.  The Company shall use its commercially reasonable efforts  to file any reports required to be filed by it under the Securities Act and the Exchange Act, and it will use its commercially reasonable efforts to take such further action as any holder may reasonably request to make available adequate current public information with respect to the Company meeting the current public information requirements of Rule 144(c) under the Securities Act, to the extent required to enable such holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or (ii) any similar rule or regulation hereafter adopted by the SEC. Notwithstanding the foregoing, nothing in this Section 2.11 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act.

27

2.12                        Inconsistent Agreements.  The Company and its controlled Affiliates shall not, without the prior written consent of the Holders of at least a majority of the Registrable Securities at the time in question, enter into any agreement with respect to the registration and/or sale of its securities that is inconsistent with or senior to the rights granted under this Article II; provided, that the grant of rights no more favorable to those in Section 2.2 and Section 2.3 shall be deemed consistent with and not senior to the rights granted in this Article II.

3.5                               Third Parties.  Except as expressly set forth herein, nothing expressed or implied in this Agreement is intended or shall be construed to confer on any Person, other than the Company and the Holders, any legal or equitable right, remedy or claim under or with respect to this Agreement or any provision of this Agreement.

3.6                               Severability.  If any one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions hereof shall not be in any way impaired, unless the provisions held invalid, illegal or unenforceable shall substantially impair the benefits of the remaining provisions hereof.
