(i) against any and all loss, liability, claim, damage and expense whatsoever,

26

as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto (including, without limitation, the Rule 430B Information) or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing) or the omission or alleged omission therefrom of 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;

(iii) against any and all expense whatsoever, as incurred (including, subject to Section 6(c) hereof, the fees and disbursements of counsel chosen by the Representatives), reasonably incurred 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 statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided , however , that the foregoing indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission (1) made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or any Preliminary Prospectus any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), it being understood that such information is limited to the Underwriter Information (as defined below) or (2) in the Form T-1.

(b) Each Underwriter, severally and not jointly agrees to indemnify and hold harmless the Company and its directors, each of its officers who signed the Registration Statement and its employees, each Guarantor and its directors, each of its officers who signed the Registration Statement and its employees, and each person, if any, who controls the Company or any Guarantor within the meaning of Section 15 of the 1933 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement or any amendment thereto (including, without limitation, the Rule 430B Information) or any Preliminary Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing) in reliance upon and in conformity with

27

written information furnished to the Company by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or such Preliminary Prospectus, such Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing); provided that the Company acknowledges that the statements set forth under the caption “Underwriting” in the Statutory Prospectus and the Prospectus (i) in the table in the first paragraph and (ii) the eighth paragraph (such statements, the “ Underwriter Information ”) constitute the only such information furnished in writing by or on behalf of each Underwriter.

(c) 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 the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. An indemnifying party may participate at its own expense in the defense of any such action. In no event shall the indemnifying parties be liable for the fees and expenses of more than one counsel (in addition to any local counsel), separate from their own counsel (i) in the case of indemnity pursuant to Section 6(a), for the Underwriters, the directors and officers of any Underwriter, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act and (ii) in the case of indemnity pursuant to Section 6(b), for the Company and its directors, each of its officers who signed the Registration Statement, and its employees, each Guarantor and its directors, and each person, if any, who controls the Company or any Guarantor within the meaning of Section 15 of the 1933 Act, in each case 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 party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is a party and indemnity is provided hereunder, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (y) 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.

SECTION 7. Contribution . In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Sections 6(a) or (b) is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, the Company and the Guarantors, on the one hand, and the Underwriters, on the other hand, shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Company and the Guarantors and one or more of the Underwriters, as incurred, in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriters be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Underwriters hereunder. For purposes of this Section 7, the benefits received by the Company and the Guarantors shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total purchase discounts

28

and commissions; provided , however , that 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, each director, officer, employee, and respective affiliate and agent, in each case only for such affiliates and agents who have, or are alleged to have, participated in the distribution of Securities, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as such Underwriter, and each director of the Company or any Guarantor, each officer of the Company or any Guarantor who signed the Registration Statement, each employee of the Company or any Guarantor, and each person, if any, who controls the Company or any Guarantor within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as the Company or such Guarantor, as the case may be. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to aggregate principal amount of Securities set forth opposite their respective names in Schedule B hereto and not joint. The obligations of the Company and the Guarantors to contribute pursuant to this Section 7 are joint and several.

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 or any of the Guarantors or any of the Company’s other subsidiaries 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 or any of the Guarantors, and shall survive delivery of the Securities to the Underwriters.

SECTION 9. Termination of Agreement .

(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 Registration Statement, the General Disclosure Package or the Prospectus, 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, or (ii) if there has occurred any material adverse change in the financial markets in the United States or any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in the securities of the Company has been suspended or materially limited by the Commission or a national securities exchange, or if trading generally on the New York Stock Exchange or the Nasdaq Global Select Market has been suspended or materially limited, 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 order of the Commission or any other governmental authority, or if a banking moratorium has been declared by either federal, New York or California authorities, or (iv) if the rating assigned by any nationally recognized statistical rating organization to any debt securities of the Company or of any subsidiary of the Company shall have been lowered or if any such rating agency shall have publicly announced that it has placed any debt securities of the

29

Company or any trust preferred securities, capital securities or similar securities of any subsidiary of the Company on what is commonly termed a “watch list” for a possible downgrading. As used in this Section 9(a), the term “Registration Statement” means the Registration Statement excluding any amendments or supplements thereto after the date of this Agreement; the term “General Disclosure Package” means the General Disclosure Package excluding any amendments or supplements thereto after the Applicable Time; and “Prospectus” means the Prospectus excluding any amendments or supplements thereto subsequent to the date of this Agreement.

(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 the Defaulted Securities does not exceed 10% of the aggregate principal amount of Securities to be purchased at Closing Time, 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 the Defaulted Securities exceeds 10% of the aggregate principal amount of Securities to be purchased at Closing Time, 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 or the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the General Disclosure Package, the 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.

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto (including, without limitation, the Rule 430B Information) or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing) or the omission or alleged omission therefrom of 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;

25

(iii) against any and all expense whatsoever, as incurred (including, subject to Section 6(c) hereof, the fees and disbursements of counsel chosen by the Representatives), reasonably incurred 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 statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided , however , that the foregoing indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or any Preliminary Prospectus any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), it being understood that such information is limited to the Underwriter Information (as defined below).

(b) Each Underwriter, severally and not jointly agrees to indemnify and hold harmless the Company and its directors, each of its officers who signed the Registration Statement and its employees, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement or any amendment thereto (including, without limitation, the Rule 430B Information) or any Preliminary Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or such Preliminary Prospectus, such Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing); provided that the Company acknowledges that the statements set forth under the caption “Underwriting” in the Statutory Prospectus and the Prospectus (i) in the table in the first paragraph and (ii) the ninth paragraph (such statements, the “ Underwriter Information ”) constitute the only such information furnished in writing by or on behalf of each Underwriter.

(c) 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 the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above.

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 a party and indemnity is provided hereunder, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (y) 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.

SECTION 7. Contribution . In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Sections 6(a) or (b) is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, the Company, on the one hand, and the Underwriters, on the other hand, shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Company and one or more of the Underwriters, as incurred, in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriters be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Underwriters hereunder. For purposes of this Section 7, the benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total purchase discounts and commissions; provided , however , that 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, each director, officer, employee, and respective affiliate and agent, in each case only for such affiliates and agents who have, or are alleged to have, participated in the distribution of Securities, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 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, each employee of the Company, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as the Company, as the case may be. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to aggregate principal amount of Securities set forth opposite their respective names in Schedule B hereto and not joint.

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

27

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 of Agreement .

(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 Registration Statement, the General Disclosure Package or the Prospectus, 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, or (ii) if there has occurred any material adverse change in the financial markets in the United States or any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in the securities of the Company has been suspended or materially limited by the Commission or a national securities exchange, or if trading generally on the New York Stock Exchange or the Nasdaq Global Select Market has been suspended or materially limited, 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 order of the Commission or any other governmental authority, or if a banking moratorium has been declared by either federal, New York or California authorities, or (iv) if the rating assigned by any nationally recognized statistical rating organization to any debt securities of the Company or of any subsidiary of the Company shall have been lowered or if any such rating agency shall have publicly announced that it has placed any debt securities of the Company or any trust preferred securities, capital securities or similar securities of any subsidiary of the Company on what is commonly termed a “watch list” for a possible downgrading.

(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.

(a) if the aggregate amount of the Defaulted Securities does not exceed 10% of the aggregate amount of Securities to be purchased at Closing Time, 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 amount of the Defaulted Securities exceeds 10% of the aggregate amount of Securities to be purchased at Closing Time, 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 or the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the General Disclosure Package, the Prospectus or in any other documents or arrangements.
