If the Company files a Form S-3 Shelf and thereafter the Company becomes ineligible to use Form S-3 for secondary sales, the Company shall use its reasonable best efforts to file a Form S-1 Shelf as promptly as reasonably practicable to replace the shelf registration statement that is a Form S-3 Shelf and have the Form S-1 Shelf declared effective as promptly as reasonably practicable and to cause such Form S-1 Shelf to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another Registration Statement is available, for the resale of all the Registrable Securities held by the Holders until all such Registrable Securities have ceased to be Registrable Securities.

2.3.3Shelf Takedown. At any time and from time to time following the effectiveness of the shelf registration statement required by subsection 2.3.1 or 2.3.2, any Holder may request to sell all or a portion of their Registrable Securities in an underwritten offering that is registered pursuant to such shelf registration statement, including a Block Trade (a “Underwritten Shelf Takedown”), provided, that such Holder(s) (a) reasonably expect aggregate gross proceeds in excess of $35,000,000 from such Underwritten Shelf Takedown or (b) reasonably expects to sell all of the Registrable Securities held by such Holder in such Underwritten Shelf Takedown but in no event less than $10,000,000 in aggregate gross proceeds (the “Shelf Threshold”). All requests for an Underwritten Shelf Takedown shall be made by giving written notice to the Company (the “Shelf Takedown Notice”). Each Shelf Takedown Notice shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown and the expected price range (net of underwriting discounts and commissions) of such Underwritten Shelf Takedown. Within five (5) business days after receipt of any Shelf Takedown Notice, the Company shall give written notice of such requested Underwritten Shelf Takedown to all other Holders of Registrable Securities (the “Company Shelf Takedown Notice”) and, subject to reductions consistent with the Pro Rata calculations in subsection 2.2.4, shall include in such Underwritten Shelf Takedown all Registrable Securities with respect to which the Company has received written requests for inclusion therein, within five (5) days after sending the Company Shelf Takedown Notice, or, in the case of a Block Trade, as provided in Section 2.5. The Company shall enter into an underwriting agreement in a form as is customary in Underwritten Offerings of securities by the Company with the managing Underwriter or Underwriters selected by the initiating Holders and shall take all such other reasonable actions as are requested by the managing Underwriter or Underwriters in order to expedite or facilitate the disposition of such Registrable Securities. In connection with any Underwritten Shelf Takedown contemplated by this subsection 2.1.3, subject to Section 3.3 and Article IV, the underwriting agreement into which each Holder and the Company shall enter shall contain such representations, covenants, indemnities and other rights and obligations of the Company and the selling stockholders as are customary in underwritten offerings of securities.

2.4Restrictions on Registration Rights. If (A) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration, and provided, that the Company has delivered written notice to the Holders prior to receipt of a Demand Registration

pursuant to subsection 2.1.1, and it continues to actively employ, in good faith, all reasonable best efforts to cause the applicable Registration Statement to become effective; (B) the Holders have requested an Underwritten Registration and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the Board such Registration would be seriously detrimental to the Company and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to defer the filing of such Registration Statement. In such event, the Company shall have the right to defer such filing for a period of not more than thirty (30) days; provided, however, that the Company shall not defer its obligation in this manner more than twice in any 12-month period.

2.5Block Trades. Notwithstanding any other provision of Article II, but subject to Sections 2.4 and 3.4, if the Holders desire to effect a Block Trade, the Holders shall provide written notice to the Company at least five (5) business days prior to the date such Block Trade will commence. As promptly as reasonably practicable, the Company shall use its reasonable best efforts to facilitate such Block Trade. The Holders shall use reasonable best efforts to work with the Company and the Underwriter(s) (including by disclosing the maximum number of Registrable Securities proposed to be the subject of such Block Trade) in order to facilitate preparation of the Registration Statement, Prospectus and other offering documentation related to the Block Trade and any related due diligence and comfort procedures.

2.6Required Holder Information. At least ten (10) business days prior to the first anticipated filing date of a Registration Statement pursuant to this Article II, the Company shall use reasonable best efforts to notify each Holder in writing (which may be by email) of the information reasonably necessary about the Holder to include such Holder’s Registrable Securities in such Registration Statement. Notwithstanding anything else in this Agreement, the Company shall not be obligated to include such Holder’s Registrable Securities to the extent the Company has not received such information, and received any other reasonably requested agreements or certificates, on or prior to the fifth business day prior to the first anticipated filing date of a Registration Statement pursuant to this Article II.

3.1.9notify the Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.4 hereof;

3.1.10permit a representative of the Holders (such representative to be selected by a majority of the participating Holders), the Underwriters, if any, and any attorney or accountant retained by such Holders or Underwriter to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that any such representatives or Underwriters enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information; and provided further, the Company may not include the name of any Holder or Underwriter or any information regarding any Holder or Underwriter in any Registration Statement or Prospectus, any amendment or supplement to such Registration Statement or Prospectus, any document that is to be incorporated by reference into such Registration Statement or Prospectus, or any response to any comment letter, without the prior written consent of such Holder or Underwriter and providing each such Holder or Underwriter a reasonable amount of time to review and comment on such applicable document, which comments the Company shall include unless contrary to applicable law;

3.3Requirements for Participation in Underwritten Offerings.

3.4Suspension of Sales; Adverse Disclosure.

If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose.

The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission, to the extent that such rule or such successor rule is available to the Company), including providing any customary legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

ARTICLE 4

INDEMNIFICATION AND CONTRIBUTION

4.1Indemnification.

4.1.1In connection with any Registration Statement in which a Holder of Registrable Securities is participating, the Company agrees to indemnify, to the extent permitted by law, each such Holder of Registrable Securities, its officers and directors and each Person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) caused by 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 omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each Person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder. Notwithstanding the foregoing, the indemnity agreement contained in this Subsection 4.1.1 shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, conditioned, or delayed.

4.1.2In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each Person who controls the Company (within the meaning of the Securities Act) and any other Holders of Registrable Securities participating in the Registration, against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each Person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3Any Person entitled to indemnification herein 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 prompt notice shall not impair any Person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party’s ability to defend such action) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and 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. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). 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 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. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4The 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 and each Holder of Registrable Securities participating in an offering 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 or such Holder’s indemnification is unavailable for any reason.

4.1.5If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party 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 omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this subsection 4.1.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability except in the case of fraud or willful misconduct by such Holder. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined by Pro Rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this subsection 4.1.5. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this subsection 4.1.5 from any Person who was not guilty of such fraudulent misrepresentation.
