If, at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(b) Opinions of Counsel. (i) At the Closing Time, the Representatives shall have received the favorable opinion, dated as of the Closing Time, of Hogan & Hartson L.L.P., counsel for the Company, in form and substance reasonably satisfactory to counsel to the Underwriters, together with signed or reproduced copies of such opinion for each of the other Underwriters, substantially to the effect set forth in Exhibit A hereto (the “Legal Opinion”).

In addition, Sidley Austin Brown & Wood LLP may rely, as to all matters governed by the laws of the State of Maryland, upon the opinion of Hogan & Hartson L.L.P.

(c) Officers’ Certificate. At the Closing Time, there shall not have been, since the respective dates as of which information is given in the Prospectus, any Material Adverse Effect, and the Representatives shall have received a certificate of the Chief Executive Officer, President or a Senior or Executive Vice President of the Company and of the chief financial or chief accounting officer of the Company, on behalf of the Company, dated as of the Closing Time, evidencing compliance with the provisions of this subsection (c), stating that (i) there has been no Material Adverse Effect, (ii) the representations and warranties of the

Company set forth in Section 1(a) hereof are accurate as though expressly made at and as of the Closing Time, (iii) the Company has performed, complied with or satisfied all conditions on its part to be performed, complied with or satisfied under this Section (other than those conditions expressly waived by the Underwriters) and (iv) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or, to such officer’s knowledge, are contemplated by the Commission.

(d) Accountant’s Comfort Letter. At the time of execution of this Agreement, the Representatives shall have received from PricewaterhouseCoopers LLP a letter dated such date, in form and substance reasonably satisfactory to the Representatives, together with signed or reproduced copies of such letters for each of the other Underwriters, to the effect that:

(i) they are an independent registered public accounting firm with respect to the Company and its subsidiaries within the meaning of the 1933 Act and the 1933 Act Regulations; (ii) it is their opinion that the consolidated financial statements and supporting schedules of the Company included or incorporated by reference in the Registration Statement and the Prospectus and covered by their opinions therein comply as to form in all material respects with the applicable accounting requirements of the 1933 Act and the 1934 Act, the 1933 Act Regulations and the 1934 Act Regulations; (iii) they have performed limited procedures, not constituting an audit, including a reading of the latest available unaudited interim consolidated financial statements of the Company and its subsidiaries, if any, a reading of the minute books of the Company and its subsidiaries, conducted inquiries of certain officials of the Company and its subsidiaries who have responsibility for financial and accounting matters and such other inquiries and procedures as may be specified in such letter, and on the basis of such limited review and procedures nothing came to their attention that caused them to believe that (A) the unaudited interim consolidated financial statements and financial statement schedules, if any, of the Company included or incorporated by reference in the Registration Statement and the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the 1934 Act and the related published rules and regulations thereunder or that any material modification should be made to the unaudited condensed interim financial statements included in or incorporated by reference in the Registration Statement and the Prospectus for them to be in conformity with generally accepted accounting principles, (B) the unaudited pro forma condensed financial statements included in or incorporated by reference in the Company’s Registration Statement, if any, do not comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X under the 1933 Act or that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of such statements or (C) at a specified date not more than three business days prior to the date of this Agreement, there has been any change in the capital stock of the Company or increase in the consolidated long term debt of the Company or any decrease in the net assets of the Company, as compared with the amounts shown in the most recent consolidated balance sheet included or incorporated by reference in the Registration Statement and the Prospectus or, during the period from the date of

the most recent consolidated statement of operations of the Company included or incorporated by reference in the Registration Statement and the Prospectus to a specified date not more than three business days prior to the date of this Agreement, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated revenues, or decrease in consolidated net income or consolidated net income per share of the Company, except in all instances for changes, increases or decreases which the Registration Statement and the Prospectus disclose have occurred or may occur; and (iv) in addition to the audit referred to in their opinions and the limited procedures referred to in clause (iii) above, they have carried out certain specified procedures, not constituting an audit, with respect to certain amounts, percentages and financial information which are included or incorporated by reference in the Registration Statement and the Prospectus and which are specified by you, and have found such amounts, percentages and financial information to be in agreement with the relevant accounting, financial and other records of the Company and its subsidiaries identified in such letter.

(e) Bring-down Comfort Letter. At the Closing Time, the Representatives shall have received from PricewaterhouseCoopers LLP a letter, dated as of the Closing Time, to the effect that they reaffirm the statements made in the letter furnished pursuant to subsection (d) of this Section 5, except that the “specified date” referred to shall be a date not more than three business days prior to the Closing Time.

(f) Additional Documents. At the Closing Time, counsel for the Underwriters shall have been furnished with such documents and opinions as they may reasonably require for the purpose of enabling them to pass upon the issuance of the Securities as herein contemplated, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company in connection with the issuance of the Securities as herein contemplated shall be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters.

(g) Rating of Securities. At or prior to the Closing Time, the Securities shall be rated at least Baa2 by Moody’s and BBB by S&P and the Company shall have delivered to the Representatives evidence reasonably satisfactory to the Representatives confirming that the Securities have such ratings; and since the date of this Agreement, there shall not have occurred a downgrading in or withdrawal of any such rating assigned to the Securities or any of the Company’s other debt securities by Moody’s or S&P, and neither Moody’s nor S&P shall have publicly announced that it has under surveillance or review, other than for possible positive implications, its rating of the Securities or any of the Company’s other debt securities.

(h) Termination of Agreement. If any condition specified in this Section 5 shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representatives by notice to the Company at any time at or prior to the Closing Time, and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Sections 6, 7, 8 and 13 shall survive any such termination and remain in full force and effect.

Section 6. Indemnification.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and any director, officer, employee or affiliate thereof, as follows:

(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), 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 the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever (including, without limitation, the reasonable 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 this 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 the Prospectus (or any amendment or supplement thereto).

(b) Indemnification of the Company, Directors, and Officers. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, 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, and any director, officer, employee or affiliate thereof, against any and all loss, liability, claim, damage and expense of the type described in the indemnity contained in subsection (a) of this Section 6, 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) or the Prospectus (or any amendment or supplement thereto) 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 the Prospectus (or any amendment or supplement thereto).

(c) Actions against Parties; Notification. Each indemnified party shall give 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 indemnifying 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 this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless (x) 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 and (y) the indemnifying party confirms in writing its indemnification obligations hereunder with respect to such settlement, compromise or judgment.

(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)(iii) 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.

Section 7. Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 6 hereof is for any reason unavailable or is insufficient to hold harmless a party indemnified thereunder, 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 issuance and sale 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 issuance and sale of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the issuance and sale 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.

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.

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.

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 purchased and sold by it to purchasers exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged omission in the Prospectus. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Securities set forth opposite their respective names in Schedule A and not joint.

For purposes of this Section 7, 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, subject in each case to the preceding two paragraphs.

Section 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company on behalf 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 or any controlling person, 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 the 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, any Material Adverse Effect, (ii) if there has occurred any material adverse change in the financial markets in the United States, any new outbreak of hostilities or any material escalation of existing hostilities, any acts of terrorism involving the United States 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 Representatives’ judgment, impracticable to market the Securities or to enforce contracts for the sale of the Securities, (iii) if trading in any of the Company’s securities has been suspended by the Commission or the New York Stock Exchange (the “NYSE”), or if trading generally on the NYSE has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by such exchange or by order of the Commission, the National Association of Securities Dealers, Inc., or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, (iv) if any downgrading or withdrawal shall have occurred with respect to the ratings assigned to the Securities or any of the Company’s other debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the 1933 Act) or if any such organization shall have publicly announced that it has under surveillance or review, other than for possible positive implications, its rating of the Securities or any of the Company’s other debt securities or (v) if a banking moratorium has been declared by either federal, New York or Maryland authorities.

(b) If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof and provided further that Sections 4, 6, 7, 8 and 13 hereof shall survive such termination and remain in full force and effect.

Section 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the 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:

(i) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased hereunder, 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

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

No action taken pursuant to this Section 10 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 (i) the Representatives or (ii) 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 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.

Section 11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to J.P.

Section 12. Parties. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their successors, heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto and their respective successors and said controlling persons and officers and directors and their successors,

heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

Section 13. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID STATE. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

Section 14. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall constitute a single instrument.

Section 15. Effect of Headings. The Article, Section and Sub-Section headings herein are for convenience only and shall not affect the construction hereof.
