(hh) Compliance with Environmental Laws. The Parent and each of its subsidiaries (i) is in compliance with any and all applicable foreign, federal, state and local laws, orders, rules, regulations, directives, decrees and judgments relating to the use, treatment, storage and disposal of hazardous or toxic substances or waste and protection of human health and safety or the environment which are applicable to their businesses (“Environmental Laws”); (ii) has received and is in compliance with all permits, licenses or other approvals required of it under applicable Environmental Laws to conduct its business; and (iii) is in compliance with all terms and conditions of any such permit, license or approval, except, with respect to clauses (i), (ii), and (iii) where such noncompliance with Environmental Laws, failure to receive required permits,

There are no costs or liabilities associated with Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties) which would, individually or in the aggregate, result in a Material Adverse Effect.

All such insurance is fully in force on the date hereof and will be fully in force as of the Closing. The Parent has no reason to believe that it and its subsidiaries will not be able to renew their existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect. Neither the Parent nor any of its subsidiaries has been denied any material insurance policy or coverage for which it has applied. Neither the Parent nor any of its subsidiaries insures risk of loss through any captive insurance, risk retention group, reciprocal group or by means of any fund or pool of assets specifically set aside for contingent liabilities other than as described in the Disclosure Package.

The Parent is not aware of any fraud, whether or not material, that involves

management or other employees who have a role in the Parent’s internal controls; and since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

Any such free writing prospectus consented to by the Company, the Parent and the Underwriter is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company and the Parent represent that they have treated and agree that they will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and have complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

Any such final term sheet is an Issuer Free Writing Prospectus and a Permitted Free Writing Prospectus for purposes of this Agreement. The Company and the Parent also consent to the use by the Underwriter of a free writing prospectus that contains only (i) (x) information describing the preliminary terms of the Securities or their offering, (y) information permitted by Rule 134, or

(z) information that describes the final terms of the Securities or their offering and that is included in the final term sheet of the Company contemplated in the first sentence of this subsection or (ii) other information that is not “issuer information,” as defined in Rule 433, it being understood that any such free writing prospectus referred to in clause (i) or (ii) above shall not be an Issuer Free Writing Prospectus for purposes of this Agreement.

7. Conditions of the Obligations of the Underwriter. The obligations of the Underwriter hereunder will be subject to the accuracy of the representations and warranties of the Company and the Parent herein (as though made on the Closing), to the accuracy of the statements of Company and Parent officers made pursuant to the provisions hereof, to the performance by the Company and the Parent of their respective obligations hereunder and to the following additional conditions precedent:

On or prior to the Closing, the Registration Statement or any amendment thereof or supplement thereto shall not contain an untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and neither the Disclosure Package, nor any Issuer Free Writing Prospectus nor the Prospectus nor any amendment thereof or supplement thereto shall contain any 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 light of the circumstances in which they were made, not misleading.

(f) Representations and Warranties. Each of the representations and warranties of the Company and the Parent contained herein shall be true and correct when made and on and as of the Closing, as if made on such date (except that those representations and warranties that address matters only as of a particular date shall remain true and correct as of such date), and all covenants and agreements herein contained to be performed on the part of the Company and the Parent and all conditions herein contained to be fulfilled or complied with by the Company and the Parent at or prior to the Closing shall have been duly performed, fulfilled or complied with in all material respects.

8. Indemnification and Contribution.

(a) Indemnification of Underwriter and Selected Dealers. The Company and the Parent will jointly and severally indemnify and hold harmless the Underwriter, Selected Dealers and their partners, members, directors, officers, employees, agents, and any “affiliate” (within the meaning of Rule 405 of the Securities Act) of such Underwriter, and each person, if any, who controls the Underwriter or Selected Dealers within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Securities Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and in the case of the Statutory Prospectus, the Prospectus or any Issuer Free Writing Prospectus, in light of the circumstances in which they were made, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company and the Parent will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company and the Parent by the Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by the Underwriter consists of the information described as such in subsection (b) below.

(b) Indemnification of Company and the Parent. The Underwriter will indemnify and hold harmless the Company and the Parent and their respective directors and officers who sign a Registration Statement and each person, if any, who controls the Company and the Parent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”), against any losses, claims, damages or liabilities to which the Underwriter Indemnified Party may become subject, under the Securities Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the

Registration Statement at any time, any Statutory Prospectus as of any time, the Prospectus, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and in the case of the Statutory Prospectus, the Prospectus or any Issuer Free Writing Prospectus, in light of the circumstances in which they were made, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company and the Parent by or on behalf of the Underwriter or their representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not the Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by or on behalf of the Underwriter or their representatives consists of the following information (the “Underwriter’s Information”) in the Prospectus furnished on behalf of each Underwriter: Paragraphs 9 and 10 under the caption “Underwriting.”

(c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section 8(c) of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. 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 selected by the indemnifying party and reasonably satisfactory to such indemnified 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 8(c) for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses

available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party; provided, however, the indemnifying party shall not be responsible for paying the fees, costs and expenses for more than one separate counsel for all indemnified parties in any one jurisdiction. No indemnifying party shall, without the prior written consent of the indemnified party, 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 an indemnified party.

(d) Contribution. If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, 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 referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company or the Parent on the one hand and the Underwriter on the other 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 or the Parent on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses but after deducting underwriting discounts and commissions) received by the Company bear to the total underwriting discounts and commissions received by the Underwriter. The relative fault 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 or the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue 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 subsection (d) 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 which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total underlying discounts and commissions received by the Underwriter with respect to the Offering exceeds the amount of any damages which such Underwriter 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. The Company, the Parent and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 8(d) was 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 Section 8(d).

9. Termination.

(a) The Underwriter shall have the right to terminate this Agreement by giving notice to the Company as hereinafter specified at any time in writing at or prior to the Closing, without liability on the part of the Underwriter to the Company, if (i) since the time of execution of this Agreement or since the date as of which information is given in the Prospectus (A) there has been any Material Adverse Effect, (B) trading in securities generally shall have been suspended on or by the New York Stock Exchange, the NYSE Amex, the NASDAQ Global Market or in the over the counter market (each, a “Trading Market”), (C) trading in any of the securities of the Company or the Parent shall have been suspended on any Trading Market or by the Commission, (D) a general moratorium on commercial banking activities shall have been declared by federal or New York state authorities or a material disruption shall have occurred in commercial banking or securities settlement or clearance services in the United States, (E) there shall have occurred any outbreak or material escalation of hostilities or acts of terrorism involving the United States or there shall have been a declaration by the United States of a national emergency or war, (F) there shall have occurred any other calamity or crisis or any material change in general economic, political or financial conditions in the United States, if the effect of any such event specified in clause (E) or (F), in the sole judgment of the Underwriter, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for such Securities at the Closing on the terms and in the manner contemplated by this Agreement, the Disclosure Package and the Prospectus, (ii) the Company or the Parent shall have failed, refused or been unable to comply with the terms of or perform any agreement or obligation under this Agreement in any material respect, other than by reason of a default by the Underwriter, or (iv) any condition to the Underwriter’s obligations hereunder is not fulfilled in any material respect. If the Underwriter elects to terminate this Agreement as provided in this Section 9(a), the Underwriter shall provide the required notice as specified in Section 11 (Notices).

(b) If this Agreement is terminated in accordance with Section 9(a) or the purchase of the Securities pursuant to the terms of this Agreement is not consummated for any reason, the Company will reimburse the Underwriter for all reasonable documented out-of-pocket expenses (including reasonable fees and disbursements of counsel) incurred by them in connection with the offering of the Securities, up to a maximum of $125,000, and the Company will have no further obligation or liability hereunder except as set forth in Sections 5(h), 8, and 9 hereof and the Underwriter will have no further obligation or liability hereunder except as set forth in Section 8 hereof.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Parent or their respective officers and of the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriter, the Company, the Parent or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Securities.
