promptly notify the Holder and, if requested by the Holder, confirm such advice in writing, when any Registration Statement, any Prospectus, or any amendment or supplement thereto has been filed (other than documents that are incorporated by reference), when a Registration Statement has become effective, and when any post-effective amendments and supplements thereto become effective if such Registration Statement or post-effective amendment is not automatically effective upon filing pursuant to Rule 462 under the Securities Act;

promptly notify the Holder and if requested by the Holder, confirm such advice in writing, if at any time a Prospectus relating to the Registrable Securities is required to be delivered (or required to be delivered but for Rule 172 under the Securities Act) under the Securities Act, (i) the representations and warranties of the Company contained in any underwriting agreement in connection with an underwritten offering of Registrable Securities under a Registration Statement cease to be true and correct in all material respects, or (ii) the Company becomes aware of the happening of any event as a result of which the applicable Registration Statement or the Prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances then existing, not misleading, and, subject to Section 5, at the request of the Holder, promptly prepare and file, and furnish to the Holder a reasonable number of copies of, a supplement to or an amendment of such Registration Statement or such Prospectus as may be necessary so that such Registration Statement or, as thereafter delivered to the purchasers of such securities, such Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances then existing, not misleading;

as promptly as practicable after the filing of the Prospectus Supplement, cooperate with the Holder to facilitate removal of restrictive legends relating to registration under the Securities Act to permit sales pursuant to the Existing Registration Statement, including instructing its transfer agent to accept requisite representation letters of the Holder and opinions of counsel to the Holder regarding the Registrable Securities, in each case that are in customary form and substance reasonably acceptable to the Company and the transfer agent;

notify the Holder, promptly after it shall receive notice thereof, of the time when such Registration Statement, or any post-effective amendments to such Registration Statement, shall have become effective, or a supplement to any Prospectus forming part of such Registration Statement has been filed or when any document is filed with the SEC which would be incorporated by reference into the Prospectus;

advise the Holder and if requested by the Holder, confirm in writing, promptly after it shall receive notice or obtain knowledge thereof, of (i) the issuance of any stop order, injunction or other order or requirement by the SEC suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and use its reasonable best efforts to prevent the issuance of any stop order, injunction or other order or requirement, (ii) any request by the SEC or any other federal or state governmental authority for amendments or supplements to a Registration Statement or related Prospectus or for additional information, (iii) the issuance by any state securities or other regulatory authority of any order suspending the qualification or exemption from qualification of any of the Registrable Securities under state securities or “blue sky” laws or the initiation or threat of initiation of any proceedings for that purpose and use its reasonable best efforts to prevent the issuance of any such order and (iv) the removal of any such stop order, injunction or other order or requirement or proceeding or the lifting of any such suspension; and

use its reasonable best efforts to obtain as soon as practicable the lifting of any stop order, injunction, or other order or requirement by the SEC or any state securities or other regulatory authority that is issued suspending the effectiveness of such Registration Statement or suspending the qualification or exemption from qualification under state securities or “blue sky” laws.

Indemnification by the Company. To the fullest extent permitted by law, the Company agrees to indemnify the Holder and each of its officers and directors and each Person, if any, that controls (within the meaning of the Securities Act) the Holder (each, a “Holder Indemnitee”), against any and all losses, claims, damages, actions, liabilities, costs and expenses (including reasonable fees, expenses and disbursements of attorneys and other professionals), joint or several, as incurred, arising out of or based upon:

any untrue or alleged untrue statement of material fact contained in any Registration Statement, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

any untrue or alleged untrue statement of material fact contained in any Prospectus, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading:

Indemnification by Holder. The Holder, to the fullest extent permitted by law, agrees to indemnify the Company, each of its officers and directors and each Person, if any, who controls the Company (within the meaning of the Securities Act) (each, a “Company Indemnitee” and together with the Holder Indemnitees, each an “Indemnitee”) against any and all losses, claims, damages, actions, liabilities, costs and expenses arising out of or based upon (i) any untrue statement or alleged untrue statement of material fact contained in a Registration Statement, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in the light of the circumstances under which they were made, if and to the extent that such statement or omission occurs from reliance upon and in conformity with written information regarding the Holder, or the Holder’s plan of distribution or ownership interest, that was furnished to the Company by the Holder for use therein, or (ii) any untrue statement or alleged untrue statement of material fact contained in the Prospectus, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, if and to the extent that such statement or omission occurs from reliance upon and in conformity with written information regarding the Holder or its plan of distribution or its ownership interests, that was furnished to the Company by the Holder specifically for use therein; provided, however, that the obligations of the Holder hereunder shall be limited to an amount equal to the net proceeds received by the Holder upon the sale of the Registrable Securities (less the aggregate amount of any damages which the Holder has otherwise been required to pay in respect of such losses, claims, damages, actions, liabilities, costs and expenses or any substantially similar loss, claim, damage, action, liability, cost and expense arising from the sale of such Registrable Securities).

Indemnification Procedures. Any party entitled to indemnification under this Agreement shall notify promptly the indemnifying party in writing of the commencement of any action or proceeding with respect to which a claim for indemnification may be made hereunder, but the failure of any Indemnitee to provide such notice shall not relieve the indemnifying party of its obligations hereunder, except to the extent the indemnifying party is materially prejudiced thereby and shall not relieve the indemnifying party from any liability which it may have to any Indemnitee otherwise than hereunder. In case any action or proceeding is brought against an Indemnitee and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, unless in the reasonable opinion of outside counsel to the Indemnitee a conflict of interest between such Indemnitee and the indemnifying party may exist in respect of such claim, to assume the defense thereof (alone or jointly with any other indemnifying party similarly notified), to the extent that it chooses, with counsel reasonably satisfactory to such Indemnitee, and after notice from the indemnifying party to such Indemnitee that it so chooses, the indemnifying party shall not be liable to such Indemnitee for any legal or other expenses subsequently incurred by such Indemnitee in connection with the defense thereof; provided, however, that (i) if such Indemnitee who is a defendant in any action or proceeding that is also brought against the indemnifying party shall have reasonably concluded, based on the advice of counsel, that there may be one or more legal defenses available to such Indemnitee which are not available to the indemnifying party, or (ii) if representation of both parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct, then, in any such case, the Indemnitee shall have the right to assume or continue its own defense as set forth above (but with no more than one firm of counsel for all Indemnitees in each jurisdiction, except to the extent any Indemnitee or Indemnitees reasonably shall have concluded, based on the opinion of counsel, that there may be legal defenses available to such party or parties that are not available to the other Indemnitees or to the extent representation of all Indemnitees by the same counsel is otherwise inappropriate under applicable standards of professional conduct) and the indemnifying party shall be liable for any expenses therefor. No

Contribution. If the indemnification provided for in this Section 4 is held by a court of competent jurisdiction to be unavailable to an Indemnitee with respect to any losses, claims, damages, actions, liabilities, costs or expenses referred to therein or is insufficient to hold the Indemnitee harmless as contemplated therein, then the indemnifying party, in lieu of indemnifying such Indemnitee, shall contribute to the amount paid or payable by such Indemnitee as a result of such losses, claims, damages, actions, liabilities, costs or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the Indemnitee, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, actions, liabilities, costs or expenses as well as any other relevant equitable considerations. The relative fault of the indemnifying party, on the one hand, and of the Indemnitee, on the other hand, shall be determined by reference to, among other factors, whether the untrue or alleged untrue statement of a material fact or omission to state a material fact relates to information supplied by the indemnifying party or by the Indemnitee and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, however, that in no event shall the obligation of any indemnifying party to contribute under this Section 4(d) exceed the amount that such indemnifying party would have been obligated to pay by way of indemnification if the indemnification provided for under Section 4 had been available under the circumstances. The Company and the Holder agree that it would not be just and equitable if contribution pursuant to this Section 4 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. In addition, no Person shall be obligated to contribute hereunder for any amounts in payment for any settlement of any action or claim, effected without such Person’s written consent, which consent shall not be unreasonably withheld, delayed or conditioned.

For purposes of this Section 4, no Indemnitee guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any indemnifying party who was not guilty of such fraudulent misrepresentation. The indemnification provided by this Section 4 shall be a continuing right to indemnification and shall survive the registration and sale of any securities by any Person entitled to indemnification hereunder and the expiration or termination of this Agreement.

Notwithstanding anything to the contrary contained in this Agreement, the Company shall have the right to defer the filing, or suspend the use by the Holder, of a Registration Statement or Prospectus for a reasonable period of time (each, a “Suspension Period”) if the Company furnishes the Holder with prompt notice of a Suspension Period as a result of the Company’s good faith judgment that it would be detrimental to the Company and its stockholders not to defer the filing, or suspend the use by the Holder, of a Registration Statement or Prospectus because such filing or use would: (i) interfere with a material pending financing, acquisition, disposition, corporate reorganization, merger, or other

The Holder agrees that, following the effectiveness of any Registration Statement relating to Registrable Securities of the Holder, it will not effect any dispositions of any of the Registrable Securities pursuant to such Registration Statement or any filings under any state securities laws at any time after the Holder has received notice from the Company to suspend dispositions as a result of the occurrence of any Suspension Period. The Holder will maintain the confidentiality of any notice of a Suspension Period delivered by the Company unless otherwise required by law or subpoena. The Holder may recommence effecting dispositions of the Registrable Securities pursuant to the Registration Statement or such filings, and all other obligations which are suspended as a result of a Suspension Period shall no longer be so suspended, following further notice to such effect from the Company, which notice shall be given by the Company promptly (but it no event more than one Business Day) after the conclusion of any such Suspension Period.

Amendments and Waivers. The provisions of this Agreement may not be amended, modified, or supplemented or waived without the prior written consent of the Company and Holder.
