If this Agreement is terminated by the Placement Agent pursuant to Section 7 or Section 8, or if the sale to the Investors of the Securities at the time of purchase is not consummated because of any refusal, inability or failure on the part of the Company to perform any agreement herein or to comply with any provision hereof, the Company shall reimburse the Placement Agent for all of its out-of-pocket expenses in accordance with the Engagement Letter, including the fees and disbursements of its counsel.

Under such circumstances, the Engagement Letter shall remain in full force and effect in accordance with its terms.

9. Indemnity and Contribution.

(a) The Company agrees to indemnify, defend and hold harmless the Placement Agent, its partners, directors and officers, and any person who controls the Placement Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which the Placement Agent or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim (or actions in respect thereof as contemplated below) arises out of or is based (i) upon any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, the Disclosure Package, the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or in a Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement, Issuer Free Writing Prospectus, Disclosure Package or Prospectus or necessary to make such information not misleading, or (ii) in whole or in part upon the inaccuracy in the representations and warranties of the Company contained herein, or (iii) in whole or in part upon any failure of the Company to perform its obligations hereunder or under law, or (iv) any act or failure to act or alleged act or failure to act by the Placement Agent in reliance upon (i), (ii) or (iii), and in connection with, or relating in any manner to the Securities or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon any matter covered by clause (i) (ii) or (iii) above; provided that the Company shall not be liable under this clause (iv) to the extent that a court of competent jurisdiction shall have determined by a

final judgment that such loss, claim, damage, liability or action resulted primarily from any such acts or failures to act undertaken or omitted to be taken by the Placement Agent through its bad faith or willful misconduct; provided further, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Placement Agent expressly for use in the Registration Statement or in a Prospectus or an Issuer Free Writing Prospectus. The indemnity in this Section 9(a) shall be in addition to any liability that the Company may otherwise have.

If any action, suit or proceeding (each, a “Proceeding”) is brought against the Placement Agent or any such person in respect of which indemnity may be sought against the Company pursuant to the foregoing paragraph, the Placement Agent or such person shall promptly notify the Company in writing of the institution of such Proceeding and the Company may assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses incurred in connection with defense thereof; provided, however, that the omission to so notify the Company shall not relieve the Company from any liability which the Company may have to the Placement Agent or any such person or otherwise pursuant to this Agreement, except to the extent that the Company was prejudiced thereby. The Placement Agent or such person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Placement Agent or of such person unless the employment of such counsel shall have been authorized in writing by the Company in connection with the defense of such Proceeding or the Company shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have been advised by counsel in writing that there may be defenses available to it or them which are different from, additional to or in conflict with those available to the Company (in which case the Company shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties, but the Company may employ counsel and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of the Company), in any of which events such fees and expenses shall be borne by the Company and paid as incurred (it being understood, however, that the Company shall not be liable for the expenses of more than one separate firm of attorneys (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The Company shall not be liable for any settlement of any Proceeding effected without

its written consent, but if settled with the written consent of the Company, the Company agrees to indemnify and hold harmless the Placement Agent and any such person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 30 business days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding 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 includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(b) The Placement Agent agrees to indemnify, defend and hold harmless the Company, its directors and officers, and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Company or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information concerning the Placement Agent furnished in writing by or on behalf of the Placement Agent to the Company expressly for use in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company), the Disclosure Package or a Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement, Disclosure Package or Prospectus or necessary to make such information not misleading. The indemnity in this Section 9(b) shall be in addition to any liability the Placement Agent may otherwise have.

If any Proceeding is brought against the Company or any such person in respect of which indemnity may be sought against the Placement Agent pursuant to the foregoing paragraph, the Company or such person

shall promptly notify the Placement Agent in writing of the institution of such Proceeding and the Placement Agent may assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses incurred in connection with defense thereof; provided, however, that the omission to so notify the Placement Agent shall not relieve the Placement Agent from any liability which the Placement Agent may have to the Company or any such person or otherwise pursuant to this Agreement, except to the extent that the Placement Agent was prejudiced thereby. The Company or such person shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Company or such person unless the employment of such counsel shall have been authorized in writing by the Placement Agent in connection with the defense of such Proceeding or the Placement Agent shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or such indemnified party or parties shall have been advised by counsel in writing that there may be defenses available to it or them which are different from or additional to or in conflict with those available to the Placement Agent (in which case the Placement Agent shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties, but the Placement Agent may employ counsel and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of the Placement Agent), in any of which events such fees and expenses shall be borne by the Placement Agent and paid as incurred (it being understood, however, that the Placement Agent shall not be liable for the expenses of more than one separate firm of attorneys (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The Placement Agent shall not be liable for any settlement of any such Proceeding effected without the written consent of the Placement Agent, but if settled with the written consent of the Placement Agent, the Placement Agent agrees to indemnify and hold harmless the Company and any such person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 30 business days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened

Proceeding 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 includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(c) If the indemnification provided for in this Section 9 is unavailable to an indemnified party under subsection (a) of this Section 9 or insufficient to hold harmless any such indemnified party in respect of any losses, damages, expenses, liabilities or claims referred to therein (except to the extent limited by such subsection (a)), then the Company shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Placement Agent on the other hand from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Placement Agent on the other in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. If the indemnification provided for in this Section 9 is unavailable to an indemnified party under subsection (b) of this Section 9 or insufficient to hold harmless any such indemnified party in respect of any losses, damages, expenses, liabilities or claims referred to therein (except to the extent limited by such subsection (b)), then the Placement Agent shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Placement Agent on the other hand from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Placement Agent on the other in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Placement Agent on the other shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of placement fees but before deducting expenses) received by the Company and the total placement fees received by the Placement Agent, bear to the aggregate public offering price of the Securities. The relative fault of the Company on the one hand and of the Placement Agent on the other shall be

determined by reference to, among other things, whether any action in question, including any untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or by the Placement Agent and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any reasonable legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(d) The Company and the Placement Agent agree that it would not be just and equitable if contribution pursuant to this Section 9 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 subsection (c) above. Notwithstanding the provisions of this Section 9, the Placement Agent shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities placed by the Placement Agent and distributed to the public were offered to the public exceeds the amount of any damage which the Placement Agent has otherwise been required to pay by reason of such untrue statement or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The indemnity and contribution agreements contained in this Section 9 and the covenants, warranties and representations of the Company contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Placement Agent, its partners, directors or officers or any person (including each partner, officer or director of such person) who controls the Placement Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of the Company, its directors or officers or any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Securities. The Company and the Placement Agent agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Company, against any of the Company’s officers or directors in connection with the issuance and sale of the Securities, or in connection with the Registration Statement or the Prospectus.

10. Relationship of Parties. The Company acknowledges and agrees that: (i) the placement of the Securities pursuant to this Agreement, including the determination of commissions, is an arm’s-length commercial transaction

between the Company, on the one hand, and the Placement Agent, on the other hand, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by the Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction the Placement Agent is and has been acting solely as a principal and is not the financial advisor or fiduciary of the Company or its affiliates, stockholders, creditors or employees or any other party; (iii) the Placement Agent has not assumed nor will it assume an advisory or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether the Placement Agent has advised or is currently advising the Company on other matters) and the Placement Agent has no obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement and the Engagement Letter; (iv) the Placement Agent and its affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and that the Placement Agent has no obligation to disclose any such interests by virtue of any advisory or fiduciary relationship; and (v) the Placement Agent has not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Placement Agent with respect to the subject matter hereof, other than the Engagement Letter. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Placement Agent with respect to any breach or alleged breach of fiduciary duty.

11. Information Furnished by the Placement Agent.
