The Company shall file the Resale Registration Statement on such form as the Company may then utilize under the rules of the SEC and use its best efforts to have the Resale Registration Statement declared effective under the Securities Act as soon as practicable, but in no event more than the earlier of: (A) 120 days following the Closing Date, and (B) five trading days after the date the Company receives written notification from the SEC that the Resale Registration Statement will not be reviewed.

2.2 Provisions Relating to Registration.

(a) Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause (i) the Resale Registration Statement (as of the effective date of the Resale Registration Statement), any amendment thereof (as of the effective date thereof) or supplement thereto (as of its date), (A) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the SEC, and (B) not to contain any 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) any related prospectus, preliminary prospectus and any amendment thereof or supplement thereto, as of its date, (A) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the SEC, and (B) not to contain any 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, in the light of the circumstances under which they were made, not misleading; provided, however, the Company shall have no such obligations or liabilities with respect to any written information pertaining to a Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein.

(b) The Company shall notify the Holders: (i) when the Resale Registration Statement or any amendment thereto has been filed with the SEC and when the Resale Registration Statement or any post-effective amendment thereto has become effective; (ii) of any request by the SEC for amendments or supplements to the Resale Registration Statement or the prospectus included therein or for additional information; (iii) of the issuance by the SEC of any stop order suspending the effectiveness of the Resale Registration Statement or the initiation of any proceedings for that purpose and of any other action, event or failure to act that would cause the Resale Registration Statement not to remain effective; and (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 of any proceeding for such purpose.

(c) As promptly as practicable after becoming aware of such event, the Company shall notify the Holders of the happening of any event (a “Suspension Event”), of which the Company has knowledge, as a result of which the prospectus included in the Resale Registration Statement as then in effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and use its best efforts promptly to prepare a supplement or amendment to the Resale Registration Statement to correct such untrue statement or omission, and deliver such number of copies of such supplement or amendment to the Holders as the Holders may reasonably request; provided, however, that, for not more than 45 consecutive trading days (or a total of not more than 120 trading days in any 12 month period), the Company may delay, to the extent permitted by and in a manner not in violation of applicable securities laws, the disclosure of material non-public information concerning the Company (as well as prospectus or Resale Registration Statement updating), the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests of the Company; provided, further, that, if the Resale Registration Statement was not filed on Form S-3, such number of days shall not include the 15 calendar days following the filing of any Current Report on Form 8-K, Quarterly Report on Form 10-Q or Annual Report on Form 10-K, or other comparable form, for purposes of filing a post-effective amendment to the Resale Registration Statement.

(d) Upon a Suspension Event, the Company shall give written notice (a “Suspension Notice”) to the Holders to suspend sales of the affected Registrable Securities, and such notice shall state that such suspension shall continue only for so long as the Suspension Event or its effect is continuing and the Company is pursuing with reasonable diligence the completion of the matter giving rise to the Suspension Event or otherwise taking all reasonable steps to terminate suspension of the effectiveness or use of the Resale Registration Statement. In no event shall the Company, without the prior written consent of the Holders, disclose to the Holders any of the facts or circumstances giving rise to the Suspension Event. The Holders shall not effect any sales of the Registrable Securities pursuant to the Resale Registration Statement (or such filings), at any time after they have received a Suspension Notice and prior to receipt of an End of Suspension Notice. The Holders may resume effecting sales of the Registrable Securities under the Resale Registration Statement (or such filings), following further notice to such effect (an “End of Suspension Notice”) from the Company. This End of Suspension Notice shall be given by the Company to the Holders in the manner described above promptly following the conclusion of any Suspension Event and its effect. For the avoidance of doubt, a Suspension Notice shall not affect or otherwise limit sales of affected Registrable Securities under Rule 144 or otherwise outside of the Resale Registration Statement.

(e) Notwithstanding any provision herein to the contrary, if the Company gives a Suspension Notice pursuant to this Section 2.2 with respect to the Resale Registration Statement, the Company shall extend the period during which the Resale Registration Statement shall be maintained effective under this Agreement by the number of days during the period from the date of the giving of the Suspension Notice to and including the date when the Holders shall have received the End of Suspension Notice and copies of the supplemented or amended prospectus necessary to resume sales.

(f) The Company shall bear all Registration Expenses incurred by the Company in connection with the registration of the Registrable Securities pursuant to this Agreement.

(g) Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be required to include Registrable Securities in the Resale Registration Statement unless the Holder owning the Registrable Securities to be registered on the Resale Registration Statement, following reasonable advance written request by the Company, furnishes to the Company, at least 10 Business Days prior to the scheduled filing date of the Resale Registration Statement, an executed stockholder questionnaire in the form attached hereto as Exhibit A.

2.3 Indemnification.

(a) In the event of the offer and sale of the Registrable Securities held by the Holders under the Securities Act, the Company agrees to indemnify and hold harmless each Holder and its directors, officers, employees, Affiliates and agents and each Person who controls such Holder within the meaning of the Securities Act or the Exchange Act (collectively, the “Holder Indemnified Parties”) from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof to which each Holder Indemnified Party may become subject under the Securities Act or the Exchange Act, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Resale Registration Statement or in any amendment thereof, in each case at the time such became effective under the Securities Act, or in the preliminary prospectus or other information that is deemed, under Rule 159 promulgated under the Securities Act to have been conveyed to purchasers of securities at the time of sale of such securities (“Disclosure Package”), in the prospectus or in any amendment thereof or supplement thereto, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Disclosure Package or any prospectus, in the light of the circumstances under which they were made) not misleading, and shall reimburse, as incurred, the Holder Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or omission made in the Resale Registration Statement, the Disclosure Package, any prospectus or in any amendment thereof or supplement thereto in reliance upon and in conformity with written information pertaining to a Holder and furnished to the Company by or on behalf of such Holder Indemnified Party specifically for inclusion therein; provided further, however, that the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in the Disclosure Package, where (A) such statement or omission had been eliminated or remedied in any subsequently filed amended prospectus or prospectus supplement (the Disclosure Package, together with such updated documents, the “Updated Disclosure Package”), the filing of which such Holder had been notified in accordance with the terms of this Agreement, (B) such Updated Disclosure Package was available at the time such Holder sold Registrable Securities under the Resale Registration Statement, (C) such Updated Disclosure Package was not furnished by such Holder to the Entity asserting the loss, liability, claim, damage or liability, or an underwriter involved in the distribution of such Registrable Securities, at or prior to the time such furnishing is required by the Securities Act, and (D) the Updated Disclosure Package would have cured the defect giving rise to such loss, liability, claim, damage or action; and provided further, however, that this indemnity agreement will be in addition to any liability that the Company may otherwise have to such Holder Indemnified Party. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any Holder Indemnified Parties and shall survive the transfer of the Registrable Securities by any Holder.

(b) As a condition to including any Registrable Securities to be offered by a Holder in any registration statement filed pursuant to this Agreement, such Holder agrees to severally and not jointly indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Resale Registration Statement, as well as any officers, employees, Affiliates and agents of the Company, and each Person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act (a “Company Indemnified Party”) from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which a Company Indemnified Party may become subject under the Securities Act or the Exchange Act, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Resale Registration Statement or in any amendment thereof, in each case at the time such became effective under the Securities Act, or in any Disclosure Package, prospectus or in any amendment thereof or supplement thereto, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Disclosure Package or any prospectus, in the light of the circumstances under which they were made) not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation immediately preceding this clause, shall reimburse, as incurred, the Company Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Holder, or any such director, officer, employees, Affiliates and agents and shall survive the transfer of such Registrable Securities by such Holder, and such Holder shall reimburse the Company, and each such director, officer, employees, Affiliates and agents for any legal or other expenses reasonably incurred by them in connection with investigating, defending, or settling and such loss, claim, damage, liability, action, or proceeding; provided, however, that the indemnity amount contained in this Section 2.3(b) shall in no event exceed the gross proceeds from the offering received by such Holder. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer, employees, Affiliates and agents and shall survive the transfer by a Holder of such Registrable Securities.

(c) Promptly after receipt by a Holder Indemnified Party or a Company Indemnified Party (each, an “Indemnified Party”) of notice of the commencement of any action or proceeding (including a governmental investigation), such Indemnified Party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 2.3, notify the indemnifying party of the commencement thereof; but the omission to so notify the indemnifying party will not relieve the indemnifying party from liability under Sections 2.3(a) or 2.3(b) unless and to the extent it did not otherwise learn of such action and the indemnifying party has been materially prejudiced by such failure. In case any such action is brought against any Indemnified Party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party (who shall not, except with the consent of the Indemnified Party, be counsel to the indemnifying party), and after notice from the indemnifying party to such Indemnified Party of its election so to assume the defense thereof the indemnifying party will not be liable to such Indemnified Party under this Section 2.3 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such Indemnified Party in connection with the defense thereof; provided, however, if such Indemnified Party shall have been advised by counsel that there are one or more defenses available to it that are in conflict with those available to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the Indemnified Party), the reasonable fees and expenses of such Indemnified Party’s counsel shall be borne by the indemnifying party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (together with appropriate local counsel) at any time for any Indemnified Party in connection with any one action or separate but substantially similar or related actions arising in the same jurisdiction out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the Indemnified Party (not to be unreasonably withheld or delayed), effect any settlement of any pending or threatened action in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party unless such settlement (i) includes an unconditional release of such Indemnified Party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party. If the indemnification provided for in this Section 2.3 is unavailable or insufficient to hold harmless an Indemnified Party under Sections 2.3(a) or 2.3(b), then each indemnifying party shall contribute to the amount paid or payable by such Indemnified Party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in Sections 2.3(a) or 2.3(b) in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and the Indemnified Party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or a Holder or Holder Indemnified Party, as the case may be, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid by an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 2.3 shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any action or claim that is the subject of this Section 2.3(c). The parties agree that it would not be just and equitable if contributions were determined by pro rata allocation (even if a Holder was treated as one Entity for such purpose) or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding any other provision of this Section 2.3(c), no Holder shall be required to contribute any amount in excess of the amount by which the net proceeds received by such Holder from the sale of the Registrable Securities pursuant to the Resale Registration Statement exceeds the amount of damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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.

(d) The agreements contained in this Section 2.3 shall survive the sale of the Registrable Securities pursuant to the Resale Registration Statement and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any Indemnified Party.

INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

This legend shall be removed by the Company from any certificate or book-entry security entitlement evidencing the Registrable Securities upon delivery by the holder thereof to the Company of a written request to that effect if at the time of such written request (i) a registration statement under the Securities Act is at that time in effect with respect to the legended security, or (ii) the legended security can be transferred in a transaction in compliance with Rule 144 under the Securities Act, and, in the case of (ii), upon the request and in the reasonable discretion of the Company’s transfer agent, the holder of such Registrable Securities executes and delivers a representation letter that includes customary representations regarding the holding requirements and whether such holder is an “affiliate” for purposes of Rule 144 under the Securities Act.
