13

(b)   Filing of Amendments.  During the Prospectus Delivery Period, the Company will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement or any amendment or supplement to the Prospectus (including any revised prospectus which the Company proposes for use by the Underwriters in connection with the offering of the Securities that differs from the prospectus filed with the Commission pursuant to Rule 424(b) of the 1933 Act Regulations, whether or not such revised prospectus is required to be filed pursuant to Rule 424(b) of the 1933 Act Regulations), will furnish the Representatives with copies of any such amendment or supplement a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file any such amendment or supplement or use any such prospec tus to which the Representatives or counsel for the Underwriters shall reasonably object.

(c)   Actions Against Parties; Notification.  Each indemnified party shall give written notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement.  In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company.  An i ndemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party.  In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.  No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under Section&nbs p;6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim 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.

23

(d)   Settlement without Consent if Failure to Reimburse.  If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(e)   EDGAR.  For purposes of this Section 6, all references to the Registration Statement, any Pre-Pricing Prospectus, Issuer Free Writing Prospectus or the Prospectus, or any amendment or supplement to any of the foregoing, shall be deemed to include, without limitation, any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR.

Section 7.  Contribution.  If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions that the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus Supplement, bear to the aggregate public offering price of the Securities as set forth on such cover.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7.  The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

24

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it were offered exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each agent of an Underwriter, and each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company.

Section 8.  Representations, Warranties and Agreements to Survive Delivery.  All representations, warranties and agreements contained in this Agreement, or contained in certificates of officers of the Company submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or any controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities to the Underwriters.

Section 9.  Termination.

(a)   The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been since the date of this Agreement or since the respective dates as of which information is given in the Prospectus or the Time of Sale Information, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, (ii) if there has occurred any material adverse change in the financial markets in the United States, any outbreak of hostilities or other calamity or crisis or change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which on the financial mark ets of the United States is such as to make it, in the judgment of the Representatives, impracticable to market the Securities or enforce contracts for the sale of the Securities, (iii) if trading in any securities of the Company has been suspended by the Commission or a national securities exchange, or if trading generally on either the American Stock Exchange or the New York Stock Exchange or in the NASDAQ Global Market has been suspended, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by either of said exchanges or by the NASDAQ Global Market or by order of the Commission, the Financial Industry Regulatory Authority or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (iv) if a banking moratorium has been declared by either federal, New York, Maryland or California authorities.  As used in this Section& nbsp;9(a), the term “Prospectus” means the Prospectus in the form first used to confirm sales of the Securities.

25

(b)   If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof.  Notwithstanding any such termination, the provisions of Sections 4, 6, 7 and 8 shall remain in effect.

Section 10.  Default by One or More of the Underwriters.  If one or more of the Underwriters shall fail at Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24 hour period, then:

(a)           if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b)           if the aggregate principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representatives, on the one hand, or the Company, on the other hand, shall have the right to postpone Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements.  As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

26

Section 11.  Certain Agreements of the Underwriters.  Each Underwriter hereby represents and agrees that:

(a)   It has not and will not use, authorize use of, refer to, or participate in the plan for use of, any “free writing prospectus,” as defined in Rule 405 of the 1933 Act Regulations other than (i) a free writing prospectus that, solely as a result of use by the Underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433 of the 1933 Act Regulations, (ii) any Issuer Free Writing Prospectus listed on Exhibit B or prepared pursuant to Section 1(a)(iii) or Section 3(c) above (including any electronic road show), or (iii) any free writing prospectus prepared by such Underwriter and approved in writing by the Company in advance of the use of such free writing prospectus.  Notwithstanding the foregoing, the Underwriters may use a term sheet substantially in th e form of Exhibit C hereto without the consent of the Company.

(b)   It is not subject to any pending proceeding under Section 8A of the 1933 Act with respect to the offering (and will promptly notify the Company if any such proceeding against it is initiated during the Prospectus Delivery Period).
