Item 1.01

Entry into a Material Definitive Agreement.

Underwriting Agreement

On August 16, 2017, Hannon Armstrong Sustainable Infrastructure Capital, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Deutsche Bank Securities Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC, as representatives of the several underwriters named in Schedule A thereto (the “Underwriters”), in connection with the offer and sale by the Company to the Underwriters of $135,000,000 aggregate principal amount of its 4.125% Convertible Senior Notes due 2022 (the “Notes”). The Underwriters have the option to purchase within 30 days of August 16, 2017 up to an additional $15,000,000 aggregate principal amount of Notes from the Company, solely to cover over-allotments. The Underwriting Agreement contains customary representations, warranties and agreements of the Company, conditions to closing, indemnification rights and obligations of the parties and termination provisions.

The public offering generated net proceeds of approximately $130.9 million, after deducting the underwriting discount and estimated offering expenses. The Company intends to contribute the net proceeds to Hannon Armstrong Sustainable Infrastructure, L.P. (the “Operating Partnership”), its operating partnership subsidiary, in exchange for the issuance by the Operating Partnership of a senior unsecured note (the “Mirror Note”) with terms that are substantially equivalent to the terms of the Notes. The Operating Partnership intends to use the net proceeds to repay outstanding borrowings under one or both of a senior secured revolving credit facility and a recourse credit facility or for general corporate purposes.

The Notes were issued under an indenture (the “Base Indenture”), dated as of August 22, 2017, between the Company and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by a supplemental indenture, dated as of August 22, 2017, between the Company and the Trustee (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”).

The Notes bear interest at a rate of 4.125% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2018. The Notes will mature on September 1, 2022 (the “Maturity Date”), unless earlier repurchased, redeemed or converted.

If the Company undergoes a “fundamental change” (as defined in the Indenture) involving the Company, subject to certain conditions, holders of the Notes may require the Company to repurchase for cash all or parts of such holders’ Notes. The fundamental change repurchase price for the Notes generally will be equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. Holders of the Notes may convert any of their Notes into shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), at the applicable conversion rate at any time prior to the close of business on the second scheduled trading day immediately preceding the Maturity Date, unless the Notes have been previously redeemed or repurchased by the Company. Following the occurrence of a make-whole fundamental change, the Company will, in certain circumstances, increase the conversion rate for a holder that converts its Notes in connection with such make-whole fundamental change.

Any conversion of Notes into shares of Common Stock will be subject to certain ownership limitations (as more fully described in the Indenture). The initial conversion rate for each $1,000 aggregate principal amount of the Notes is 36.7107 shares of Common Stock, equivalent to a conversion price of approximately $27.24 per share of Common Stock, which is approximately a 20% premium to the closing price of the Common Stock on August 16, 2017. The conversion rate is subject to adjustment in certain circumstances.

The Company may redeem the Notes prior to September 1, 2022, to the extent the Company’s board of directors determines such redemption is reasonably necessary to preserve its qualification as a real estate investment trust (“REIT”) for U.S. federal income tax purposes. If the Company determines that redeeming the Notes is necessary to preserve its qualification as a REIT, then it may at any time prior to maturity redeem all or part (in a principal amount that is integral multiple of $1,000) of the Notes at a cash redemption price equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, if any, but excluding, the redemption date.

On or after March 1, 2022, the Company may redeem the Notes for cash, in whole or from time to time in part, at its option, at a redemption price equal to the sum of (i) 100% of the principal amount of the Notes to be redeemed, (ii) accrued and unpaid interest (including additional interest, if any) thereon to, but excluding, the redemption date and (iii) the make-whole premium. The Company will give notice of any redemption not less than 15 nor more than 30 calendar days before the redemption date to holders of the Notes.

-2-

Except as described in the Indenture, if an event of default with respect to the Notes occurs, holders of the Notes may, upon satisfaction of certain conditions, accelerate the principal amount of the Notes plus accrued and unpaid interest. In addition, the principal amount of the Notes plus accrued and unpaid interest will automatically become due and payable in the case of certain types of bankruptcy or insolvency or events of default involving the Company.

The Notes are the senior unsecured obligations of the Company and rank (i) senior in right of payment to any future indebtedness the Company may have that is expressly subordinated in right of payment to the Notes; (ii) equal in right of payment to the Company’s future unsecured indebtedness that is not so subordinated; (iii) effectively junior in right of payment to any of the Company’s existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness; and (iv) structurally subordinated to all existing and future indebtedness (including trade payables) and any future preferred equity interests of the Company’s subsidiaries as well as to any of the Company’s existing or future indebtedness that may be guaranteed by any of the Company’s subsidiaries (to the extent of any such guarantee), except for the future unsecured and unsubordinated indebtedness of the Operating Partnership with which the Notes will rank equal in right of payment, including but not limited to the Mirror Note.

The preceding description is qualified in its entirety by reference to the Underwriting Agreement, the Base Indenture and the Supplemental Indenture, copies of which are attached as Exhibits 1.1, 4.1 and 4.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.

Ladies and Gentlemen:

(“Deutsche Bank”), Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill Lynch”) and J.P. Morgan Securities LLC (“J.P. Morgan”) and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Deutsche Bank, Merrill Lynch and J.P. Morgan are acting as representatives (in such capacity, the “Representatives”), with respect to (i) the sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amount of 4.125% Convertible Senior Notes due 2022 (the “Firm Notes”) set forth in Schedule A hereto and (ii) the grant by the Company to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase up to an additional $15,000,000 aggregate principal amount of 4.125% Convertible Senior Notes due 2022 (the “Additional Notes”). The Firm Notes and all or any part of the Additional Notes subject to the option described in Section 2(b) hereof are herein called, collectively, the “Notes.”

The Notes will be issued under an indenture to be dated as of August 22, 2017 (the “Base Indenture”) between the Company and U.S. Bank, National Association, as Trustee (the “Trustee”), as supplemented by a supplemental indenture (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”). The Notes will be issued to Cede & Co., as nominee of The Depository Trust Company (“DTC”) pursuant to a blanket letter of representations, to be dated as of August 15, 2017 (the “DTC Agreement”), between the Company and DTC. The Notes will be convertible into shares (the “Underlying Securities”) of common stock of the Company, par value $0.01 per share (the “Common Stock”).

The Company understands that the Underwriters propose to make a public offering of the Notes as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (No. 333-215229), covering the public offering and sale of certain securities, including the Notes, under the Securities Act of 1933, as amended (the “1933 Act”), and the rules and regulations promulgated thereunder (the “1933 Act Regulations”), which shelf registration statement has become effective under Rule 462(e) under the 1933 Act Regulations (“Rule 462(e)”). Such registration statement, as of any time, means such registration statement as amended by any post-effective amendments thereto to such time, including the exhibits and any schedules thereto at such time, the documents incorporated or deemed to be incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the 1933 Act and the documents otherwise deemed to be a part thereof as of such time pursuant to Rule 430B under the 1933 Act Regulations (“Rule 430B”), is referred to herein as the “Registration Statement;” provided, however, that the “Registration Statement” without reference to a time means such registration statement as amended by any post-effective amendments thereto as of the time of the first contract of sale for the Notes, which time shall be considered the “new effective date” of such registration statement with respect to the Notes within the meaning of paragraph (f)(2) of Rule 430B, including the exhibits and schedules thereto as of such time, the documents incorporated or deemed to be incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the 1933 Act and the documents otherwise deemed to be a part thereof as of such time pursuant to Rule 430B. Each preliminary prospectus used in connection with the offering of the Notes, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, are collectively referred to herein as a “preliminary prospectus.” Promptly after execution and delivery of this Agreement, the Company will prepare and file a final prospectus relating to the Notes in accordance with the provisions of Rule 424(b) under the 1933 Act Regulations (“Rule 424(b)”). The final prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Notes, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under

the 1933 Act, are collectively referred to herein as the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”).

SECTION 1. Representations and Warranties .

(a) Representations and Warranties by the Company. The Company represents and warrants to each Underwriter as of the date hereof, the Applicable Time, the Closing Time (as defined below) and any Date of Delivery (as defined below), and agrees with each Underwriter, as follows:

(i) Registration Statement and Prospectuses . The Company meets the requirements for use of Form S-3 under the 1933 Act. The Registration Statement is an “automatic shelf registration statement” (as defined in Rule 405) and the Notes have been and remain eligible for registration by the Company on such automatic shelf registration statement. Each of the Registration Statement and any post-effective amendment thereto has become effective under the 1933 Act. No stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto has been issued under the 1933 Act, no order preventing or suspending the use of any preliminary prospectus or the Prospectus has been issued and no proceedings for any of those purposes have been instituted or, to the Company’s knowledge, are pending or contemplated by the Commission. The Company has complied with each request (if any) from the Commission for additional information.

Each of the Registration Statement and any post-effective amendment thereto, at the time of its deemed effectiveness and at each effective date with respect to the Underwriters pursuant to Rule 430B(f)(2) under the 1933 Act Regulations, complied in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations. Each preliminary prospectus, the Prospectus and any amendment or supplement thereto, at the time each was filed with the Commission, complied in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and each preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

The documents incorporated or deemed to be incorporated by reference in the Registration Statement and the Prospectus, when they became effective or at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act and the rules and regulations of the Commission under the 1934 Act (the “1934 Act Regulations”).

Page 4

(ii) Accurate Disclosure . Neither the Registration Statement nor any amendment thereto, at its effective time, at the Closing Time or at any Date of Delivery, contained, contains or will contain an untrue statement of a material fact or omitted, omits or will omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As of the Applicable Time, neither of (A) the General Disclosure Package and (B) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Neither the Prospectus nor any amendment or supplement thereto (including any prospectus wrapper), as of its issue date, at the time of any filing with the Commission pursuant to Rule 424(b), at the Closing Time or at any Date of Delivery, will include an untrue statement of a material fact or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus, at the time the Registration Statement became effective or when such documents incorporated by reference were filed with the Commission, as the case may be, when read together with the other information in the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, did not and will not include an 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 not misleading.

The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement (or any post-effective amendment thereto), the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein. For purposes of this Agreement, the only information so furnished shall be the information in the first and second paragraphs under the heading “Underwriting-Price Stabilization, Short Positions and Penalty Bids,” in the third and fourth sentences in the paragraph under the heading “Underwriting-No Prior Market” and the information under the heading “Underwriting-Electronic Distribution” in each case contained in the Prospectus (collectively, the “Underwriter Information”).

(iii) Issuer Free Writing Prospectuses . No Issuer Free Writing Prospectus conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein, and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified. Any offer that is a written communication relating to the Notes made prior to the initial filing of the

Page 5

Registration Statement by the Company or any person acting on its behalf (within the meaning, for this paragraph only, of Rule 163(c) of the 1933 Act Regulations) has been filed with the Commission in accordance with the exemption provided by Rule 163 under the 1933 Act Regulations (“Rule 163”) and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the 1933 Act provided by Rule 163.

(iv) Well-Known Seasoned Issuer .

(v) Company Not Ineligible Issuer . At the time of filing the Registration Statement and any post-effective amendment thereto, at the earliest time thereafter that the Company made a bona fide offer (within the meaning of Rule 164(h)(2) of the 1933 Act Regulations) of the Notes and at the date hereof, the Company was not and is not an “ineligible issuer,” as defined in Rule 405, without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an ineligible issuer.

Page 17

The option hereby granted may be exercised for 30 days after the date hereof and may be exercised in whole or in part at any time from time to time upon notice by the Representatives to the Company setting forth the principal amount of Additional Notes as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Additional Notes. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representatives, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time. If the option is exercised as to all or any portion of the Additional Notes, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the principal amount of Additional Notes then being purchased which the principal amount of Firm Notes set forth in Schedule A opposite the name of such Underwriter bears to the aggregate principal amount of Firm Notes.

(c) Payment. Payment of the purchase price for the Firm Notes shall be made at the offices of Freshfields Bruckhaus Deringer US LLP, or at such other place as shall be agreed upon by the Representatives and the Company, at 9:00 A.M.

(New York City time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Company (such time and date of payment and delivery being herein called “Closing Time”).

In addition, in the event that any or all of the Additional Notes are purchased by the Underwriters, payment of the purchase price for such Additional Notes shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representatives and the Company, on each Date of Delivery as specified in the notice from the Representatives to the Company.

Payment shall be made to the Company by wire transfer of immediately available funds to bank accounts designated by the Company, against delivery to the Representatives for the respective accounts of the Underwriters of electronic book entries for the Notes to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Firm Notes and the Additional Notes, if any, which it has agreed to purchase. The Representatives, individually and not as representatives of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Firm Notes or the Additional Notes, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(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 any information deemed to be a part thereof pursuant to Rule 430B, 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 included (A) in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto), or (B) in any roadshow or investor presentations made to investors by the Company (whether in person or electronically), or the omission or alleged omission in any preliminary prospectus, Issuer Free Writing Prospectus, Prospectus or in any roadshow or investor presentations made to investors by the Company (whether in person or electronically) 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;

Page 27

(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;

(iii) against any and all expense whatsoever, as incurred (including 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 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 the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(b) Indemnification of Company and Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers 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 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 any information deemed to be a part thereof pursuant to Rule 430B, the General Disclosure Package, any preliminary prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(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

Page 28

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 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.

(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.

Page 29

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 Notes 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 Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate principal amount of the Notes 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 (even if the Underwriters were treated as one entity for such purpose) 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.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Notes underwritten by it and distributed to the public.

Page 30

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 person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates and selling agents 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. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Firm Notes set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive . All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors or any person controlling the Company and (ii) delivery of and payment for the Notes.

SECTION 9. Termination of Agreement .

(a) Termination. 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, in the judgment of the Representatives, since the time of execution 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 Effect, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, 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 or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Notes, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or (iv) if trading generally on the New York Stock Exchange or in the Nasdaq Global Market 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 any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (vi) if a banking moratorium has been declared by either Federal or New York authorities.

Page 31

(b) Liabilities. 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, and provided further that Sections 1, 6, 7, 8, 14, 15 and 16 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 or a Date of Delivery to purchase the Notes 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 number of Defaulted Securities does not exceed 10% of the principal amount of Notes to be purchased on such date, 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 number of Defaulted Securities exceeds 10% of the principal amount of Notes to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase, and the Company to sell, the Additional Notes to be purchased and sold on such Date of Delivery 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 or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Additional Notes, as the case may be, either the (i) Representatives or (ii) the Company shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or 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.

The exact stock prices and effective dates may not be set forth in the table above, in which case:

•

if the stock price is between two stock prices in the table or the effective date is between two effective dates in the table, the number of additional shares will be determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day year;

•

if the stock price is greater than $40.00 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), no additional shares will be added to the conversion rate; or

•

if the stock price is less than $22.70 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), no additional shares will be added to the conversion rate.

Notwithstanding the foregoing, in no event will the conversion rate be increased on account of a make-whole fundamental change to exceed 44.0528 shares of our common stock per $1,000 principal amount of Notes, subject to adjustment in the same manner as the conversion rate is required to be adjusted as set forth under “Description of the Notes—Conversion Rights—Conversion Rate Adjustments” in the Preliminary Prospectus Supplement.

An explanation of the significance of a rating may be obtained from the rating agency. Generally, rating agencies base their ratings on such materials and information, and such of their own investigations, studies and assumptions, as they deem appropriate. The rating of the Notes should be evaluated independently from similar ratings of other securities. A credit rating of a security is not a recommendation to buy, sell or hold securities and may be subject to review, revision, suspension, reduction or withdrawal at any time by the assigning rating agency.

(b) The Trustee’s certificate of authentication will be substantially in the form of Exhibit A.

Section 2.02. Amount Unlimited; Issuable in Series . The aggregate principal amount of the Securities which may be authenticated and delivered under this Indenture is unlimited.

The Securities may be issued in one or more series. Prior to the issuance of Securities of a series, the Company and the Trustee will execute a Supplemental Indenture which will set forth as to the Securities of that series, to the extent applicable:

(a) the title of the Securities;

(b) any limit upon the aggregate principal amount of Securities which may be issued;

(d) the rate or rates (which may be fixed or variable) at which the Securities will bear interest, if any, the dates from which interest will accrue, the dates on which interest will be payable and the record date for the interest payable on any interest payment date;

(e) the currency or currencies in which principal, premium, if any, and interest, if any, will be payable;

(f) the place or places where principal of, premium, if any, and interest, if any, on the Securities will be payable;

- 4 -

(g) any provisions regarding the right of the Company to redeem Securities or of holders to require the Company to redeem Securities;

(h) the right, if any, of holders of the Securities to convert them into stock or other securities of the Company, including any provisions intended to prevent dilution of those conversion rights;

(i) any provisions by which the Company will be required or permitted to make payments to a sinking fund which will be used to redeem Securities or a purchase fund which will be used to purchase Securities;

(j) the percentage of the principal amount of the Securities which is payable if maturity of the Securities is accelerated because of a default; and

(k) any other terms of the Securities.

Section 2.03. Denominations . Unless otherwise provided in the Supplemental Indenture relating to a series of Securities, the Securities of each series will be issuable in registered form without coupons, in denominations of $1,000 and any integral multiple thereof unless otherwise specified as to any series in the applicable Supplemental Indenture.

Section 2.04. Execution and Authentication . Two Officers will sign the Securities of each series for the Company by manual or facsimile signature. If an Officer whose signature is on a Security no longer holds office at the time the Trustee authenticates the Security, the Security will be valid nonetheless.

A Security will not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature will be conclusive evidence that the Security has been authenticated under this Indenture.

Section 2.05. Registrar and Paying Agent . The Company will maintain an office or agency where Securities of each series may be presented for conversion, registration of transfer or for exchange (the “ Registrar ”) and an office or agency where Securities of each series may be presented for payment (“ Paying Agent ”). The Registrar will keep a register of the Securities of each series and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent.

The Company will enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture which will incorporate the terms of the TIA. The agreement will implement the provisions of this Indenture that relate to that agent. The Company will notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee will act as such. The Company or any Subsidiary may act as Paying Agent, Registrar, co-registrar or transfer agent.

The Company initially appoints the Trustee to act as Registrar and Paying Agent in connection with the Securities of each series, except in instances in which the Supplemental Indenture relating to a series of Securities appoints a different Registrar or Paying Agent. In acting hereunder and in connection with the Securities, the Paying Agent and Registrar shall act solely as agents of the Company, and will not thereby assume any obligations towards or relationship of agency or trust for or with any Holder of any Series of Securities.

- 5 -

Section 2.06. Paying Agent to Hold Money in Trust . Prior to each due date of the principal of, premium, if any, or interest, if any, on any Security, the Company will deposit with the Paying Agent a sum sufficient to pay that principal, premium or interest when due. The Paying Agent will hold in trust for the benefit of the Holders of the Securities of a series, and if the Paying Agent is not the Trustee, in trust for the benefit of the Trustee, all sums held by the Paying Agent for the payment of principal, premium or interest on the Securities of that series and, in the case of a Paying Agent other than the Trustee, the Paying Agent will give the Trustee notice of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it will segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent will have no further liability for the money.

Section 2.07. Securityholder Lists . The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of the Holders of the Securities of each series. If the Trustee is not the Registrar, the Company will furnish to the Trustee in writing (a) at least five Business Days before each Interest Payment Date and (b) at such other times as the Trustee may request in writing, all information in the possession or control of the Company or its Paying Agent as to the names and addresses of Holders of the Securities of a series; provided , however , that if the provisions of (a) and (b) do not provide for the furnishing of such information at stated intervals of not more than six months, at least as frequently as semiannually.

Section 2.08. Transfer and Exchange . Unless otherwise provided in the Supplemental Indenture relating to Securities of a series, Securities which are issued in registered form will be transferred only upon the surrender of the Securities for registration of transfer. When a Security is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar will register the transfer as requested if the requirements of Article VIII of the New York Uniform Commercial Code are met. When Securities are presented to the Registrar or a co-registrar with a request to exchange them for an equal principal amount of Securities of the same series of other denominations, the Registrar will make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the Company will execute and, upon receipt of written direction from the Company, the Trustee will authenticate Securities at the Registrar’s or co-registrar’s request. The Company will not charge a fee for transfers or exchanges.

The Company will not be required to make, and the Registrar need not register, transfers or exchanges of (i) Securities selected for redemption (except, in the case of Securities to be redeemed in part, transfers or exchanges of the portion of the Securities not to be redeemed) or (ii) any Securities of a series for a period of 15 days before the first mailing of a notice of the Securities of that series which are to be redeemed.

- 6 -

Prior to the due presentation for registration or transfer of any Security which was issued in registered form, the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar may deem and treat the person in whose name the Security is registered as the absolute owner of the Security for all purposes, and none of the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar will be affected by notice to the contrary.

Neither the Trustee nor any Agent shall have any responsibility or liability for any actions taken or not taken by the depository. The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in the Depositary or any other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption or repurchase) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders of the Securities and all payments to be made to Holders under the Securities shall be given or made only to the registered Holders of the Securities (which shall be the Depositary or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among participants in the Depositary or beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.09. Replacement Securities . If a mutilated Security which had been issued in registered form is surrendered to the Registrar or if the Holder presents evidence to the satisfaction of the Company and the Trustee that a Security which had been issued in registered form has been lost or destroyed, the Company will issue and, upon receipt of written direction from the Company, the Trustee will authenticate a replacement Security of the same series if the requirements of Section 8-405 of the New York Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. The replacement Security will not be issued until the Holder furnishes an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent and the Registrar or any co-registrar from any loss which any of them may suffer if the Security is replaced. The Company may charge the Holder for its expenses in replacing a Security.

Every replacement Security will be an obligation of the Company, even if the replaced Security is subsequently found.

- 7 -

Section 2.10. Outstanding Securities . The Securities outstanding at any time will be all the Securities authenticated by the Trustee, except those cancelled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Security does not cease to be outstanding because the Company or its affiliate holds the Security.

If a Security is replaced pursuant to Section 2.09, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser (in which case the replaced Security will be treated as outstanding to the extent permitted by Section 8-210 of the New York Uniform Commercial Code).

If the Paying Agent (other than the Company or a Subsidiary) segregates and holds in trust, in accordance with this Indenture, on a redemption date or Maturity Date money sufficient to pay all principal, premium, if any, and interest, if any, payable on that date with respect to the Securities to be redeemed or maturing, as the case may be, then on that date those Securities will cease to be outstanding and interest on them will cease to accrue.

Section 2.11. Temporary Securities . Until definitive Securities of a series are ready for delivery, the Company may prepare and, upon receipt of written direction from the Company, the Trustee will authenticate temporary Securities of that series. Temporary Securities will be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company will prepare and, upon receipt of written direction from the Company, the Trustee will authenticate definitive Securities and deliver them in exchange for temporary Securities.

Section 2.12. Cancellation . The Company at any time may deliver Securities of a series to the Trustee for cancellation and the Trustee will reduce accordingly the aggregate amount of the Securities of that series which are outstanding. The Registrar and the Paying Agent will forward to the Trustee any Securities surrendered to them for registration of transfer, exchange, payment, or conversion. The Trustee and no one else will cancel and dispose of (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment, conversion or cancellation and deliver evidence of such disposal to the Company. Subject to Section 2.09, the Company may not issue new Securities of a series to replace Securities of the series it has redeemed, paid, converted or delivered to the Trustee for cancellation.

Section 2.13. Defaulted Interest . If the Company defaults in a payment of interest on the Securities of a series, it will pay defaulted interest (plus interest on such defaulted interest to the extent lawful) to the persons who are Holders of the Securities of that series on a subsequent special record date, which date will be at least five Business Days prior to the payment date. The Company will fix the special record date and payment date, and, at least 15 days before the special record date, the Company will mail to each Holder of Securities of that series a notice that states the special record date, the payment date and the amount of defaulted interest and any interest on that defaulted interest which is to be paid. Notwithstanding the foregoing, the Company may pay defaulted interest in any other lawful manner.

- 8 -

Section 2.14. CUSIP Numbers . The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that the Trustee shall have no liability for any defect in the “CUSIP” numbers as they appear on the any Security, notice or elsewhere, and, provided further that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

ARTICLE III

REDEMPTION

Section 3.01. Company’s Option to Redeem . The Company will have the option to redeem Securities of a series only to the extent, if any, and only on the terms, set forth in the Supplemental Indenture relating to the Securities of that series. If the Company has the option to redeem Securities of a series, unless otherwise provided in the Supplemental Indenture relating to the series, the terms of the redemption will include those set forth in Sections 3.02 through 3.06.

Section 3.02. Notices to Trustee . If the Company elects to redeem Securities of a series, it will notify the Trustee of the redemption date and the principal amount and series of Securities to be redeemed. The Company will give each notice provided for in this Section at least 15 days before the redemption date. If fewer than all the Securities of a series are to be redeemed, the record date for determining which Securities of the series are to be redeemed will be selected by the Company, which will give notice of the record date to the Trustee at least 5 days before the record date.

Section 3.03. Selection of Securities to be Redeemed . If fewer than all the Securities of a series are to be redeemed at the Company’s option, the Trustee will select the Securities of that series to be redeemed by lot or, in its sole discretion, pro-rata or in accordance with the customary procedures of the depository. The Trustee will make the selection from outstanding Securities of that series not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than the minimum denomination in which Securities of the applicable series may be issued. Securities and portions of Securities the Trustee selects will be in amounts equal to the minimum denomination in which Securities of the applicable series may be issued and multiples of that amount. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee will notify the Company promptly of the Securities or portions of Securities to be redeemed.

Section 3.04. Notice of Redemption at the Company’s Option . At least 10 days and not more than 60 days before a date set for redemption at the Company’s option, the Company will mail a notice of redemption by first-class mail to each Holder of Securities to be redeemed in whole or in part.

- 9 -

The notice will identify the principal amount and series of each Security (including the CUSIP number) to be redeemed and will state:

(a) the redemption date;

(b) the redemption price plus accrued interest, if any;

(d) that Securities called for redemption in whole or in part must be surrendered to the Paying Agent to collect the redemption price plus accrued interest, if any;

(e) any conditions precedent to such redemption;

(f) that (subject to any applicable conditions precedent), unless the Company defaults in making the redemption payment, interest on Securities (or portions of Securities) called for redemption will cease to accrue on the redemption date and, if applicable, that those Securities (or the portions of then called for redemption) will cease on the redemption date (or such other date as is provided in the Supplemental Indenture relating to the Securities) to be convertible into, or exchangeable for, other securities or assets;

(g) if applicable, the current conversion or exchange price; and

(h) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Securities.

At the Company’s request, pursuant to an Officers’ Certificate delivered to the Trustee at least 15 days prior to the redemption date, the Trustee will give the notice of redemption in the Company’s name and at the Company’s expense. In such event, the Company will provide the Trustee with the information required by clauses (a) through (c), (e) and (g).

Section 3.05. Effect of Notice of Redemption . Once notice of redemption is mailed, Securities, or portions of Securities called for redemption will become due and payable on the redemption date and at the redemption price. Notice of redemption may, at the Company’s option and discretion, be subject to one or more conditions precedent. Subject to any such conditions precedent, (i) upon surrender to the Paying Agent, those Securities will be paid at the redemption price, plus accrued and unpaid interest to the redemption date, and (ii) on and after the date fixed for redemption (unless the Company defaults in the payment of the redemption price, together with interest accrued to the redemption date) interest on the Securities, or portions of them, which are redeemed will cease to accrue and any right to convert those Securities into, or exchange them for, other securities or assets will terminate and those Securities will cease to be convertible or exchangeable. Failure to give notice or any defect in the notice to any Holder will not affect the validity of the notice to any other Holder.

Section 3.06. Deposit of Redemption Price . No later than 10:00 a.m. Eastern Time on the redemption date specified in a notice of redemption, the Company will deposit with the Paying Agent (or, if the Company or a Subsidiary is the Paying Agent, segregate and hold in trust) money sufficient to redeem on the redemption date all the Securities called for redemption

- 10 -

on that redemption date at the appropriate redemption price, together with accrued interest to the redemption date, other than Securities or portions of Securities called for redemption which have been delivered by the Company to the Trustee for cancellation or Securities which have been surrendered for conversion or exchange. If any Securities called for redemption are converted or exchanged, any money deposited with the Paying Agent for redemption of those Securities will be paid to the Company upon its request, or, if the money is held in trust by the Company or a Subsidiary as Paying Agent, the money will be discharged from the trust.

Section 3.07. Holder’s Right to Require Redemption . Holders of Securities of a series will have the right to require the Company to redeem those Securities only to the extent, and only on the terms, set forth in the Supplemental Indenture relating to the Securities of that series. If Holders of Securities of a series have the right to require the Company to redeem those Securities, unless otherwise provided in the Supplemental Indenture relating to the Securities of that series, the terms of the redemption will include those set forth in Section 3.08.

Section 3.08 Procedure for Requiring Redemption . If a Holder has the right to require the Company to redeem Securities, to exercise that right, the Holder must deliver the Securities to the Paying Agent, endorsed for transfer and with the form on the reverse side entitled “Option to Require Redemption” completed. Delivery of Securities to the Paying Agent as provided in this Section will constitute an irrevocable election to cause the specified principal amount of Securities to be redeemed. When Securities are delivered to the Paying Agent as provided in this Section, unless the Company fails to make the payments due as a result of the redemption within 20 days after the Securities are delivered to the Paying Agent as provided in this Section interest on the Securities will cease to accrue and, if the Securities are convertible or exchangeable, the Holder’s right to convert or exchange the Securities will terminate.

The Company’s determination of all questions regarding the validity, eligibility (including time of receipt) and acceptance of any Security for redemption will be final and binding.

Section 3.09. Securities Redeemed in Part . Upon surrender of a Security that is redeemed in part, the Company will execute and the Trustee will authenticate and deliver to the Holder (at the Company’s expense) a new Security equal of the same series in principal amount equal to the unredeemed portion of the Security which was surrendered.

Delivery of such reports, information and documents to the Trustee as may be required under this Section 4.02 is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 4.03. Corporate Existence . Subject to Article V, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, rights (charter and statutory) and franchises; provided , however , that the Company will not be required to preserve any such right or franchise if the Board of Directors determines that the preservation of the right or franchise is no longer desirable in the conduct of the business of the Company and that its loss will not be disadvantageous in any material respect to the Holders of Securities of any series.

DEFAULTS AND REMEDIES

Section 6.01. Events of Default . An “ Event of Default ” occurs if:

(a) The Company defaults in the payment of interest on any Security of any series when it becomes due and payable and the default continues for a period of 30 days (or such other period, which may be no period) as is specified in the Supplemental Indenture relating to the series;

(b) The Company defaults in the payment of the principal of, or premium, if any, on any Security of any series as and when it becomes due and payable at its stated maturity or upon redemption, acceleration or otherwise and, if provided in the Supplemental Indenture relating to a series, the default continues for a period specified in the Supplemental Indenture;

- 13 -

(c) The Company fails to comply with any of its other covenants or agreements with regard to Securities of a series or this Indenture (other than a covenant or agreement, a default in whose performance or whose breach is dealt with specifically elsewhere in this Section) and that failure continues for a period of 60 days after the date of the notice specified below;

(d) the Company, pursuant to any Bankruptcy Law applicable to the Company:

(i) commences a voluntary case;

(ii) consents to the entry of an order for relief against it in an involuntary case;

(iii) consents to the appointment of a Custodian of it or for any substantial part of its property; or

(iv) makes a general assignment for the benefit of its creditors; or

(e) a court of competent jurisdiction enters an order or decree under any applicable Bankruptcy Law:

(i) for relief in an involuntary case;

(ii) appointing a Custodian of the Company or for any substantial part of its property; or

(iii) ordering its winding up or liquidation; and the order or decree remains unstayed and in effect for 90 days.

Each of the occurrences described in clauses (a) through (e) will constitute an Event of Default whatever the reason for the occurrence and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

The term “ Bankruptcy Law ” means Title 11 of the United States Code or any similar United States Federal or State law for the relief of debtors. The term “ Custodian ” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

A Default under clause (c) of this Section is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities of a series with regard to which the Company has failed to comply with a covenant or agreement notify the Company and the Trustee, of the Default and the Company does not cure the Default within 60 days after the giving of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a “ Notice of Default .”

- 14 -

A Default under clause (a), (b) or (c) with regard to Securities of a series will not constitute a Default with regard to Securities of any other series except to the extent, if any, provided in the Supplemental Indenture relating to the other series.

The Company will deliver to the Trustee, within 20 days after it occurs, written notice in the form of an Officers’ Certificate of any event of which the Company is aware which with the giving of notice and the lapse of time would become an Event of Default under clause (c), its status and what action the Company is taking or proposes to take with respect to it.

Section 6.02. Acceleration . If an Event of Default as to the Securities of a series occurs and is continuing, unless the principal of all of the Securities of the series has already become due and payable, the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities of the series then outstanding by notice to the Company and the Trustee, may declare the principal of and accrued interest, if any, on all the Securities of the series to be due and payable. Upon such a declaration, that principal and interest will be due and payable immediately. If an Event of Default specified in Section 6.01(d) or (e) occurs, the principal of, premium, if any, and accrued interest, if any, on all the Securities will automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders. The Holders of a majority in principal amount of the Securities of a series then outstanding, on behalf of the Holders of all the Securities of the series, by written notice to the Trustee may rescind an acceleration and its consequences if all existing Events of Default have been cured or waived except nonpayment of principal, premium, if any, or interest, if any, that has become due solely because of acceleration, and if the rescission would not conflict with any judgment or decree. No such rescission will affect any subsequent default or impair any consequent right.

Section 6.03. Other Remedies . If an Event of Default as to a series occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium, if any, and interest, if any, on the Securities of the series or to enforce the performance of any provision under this Indenture or any applicable Supplemental Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default will not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 6.04. Waiver of Existing Defaults . The Holders of a majority in aggregate principal amount of the Securities of a series then outstanding, on behalf of the Holders of all the Securities of that series, by written notice to the Trustee may consent to the waiver of any past Default with regard to Securities of the series and its consequences except (i) a default in the payment of interest or premium, if any, on, or the principal of, Securities of the series, or (ii) a default in respect of a covenant or a provision that under Section 9.02 cannot be modified or amended without the consent of the Holders of all Securities of the series then outstanding. The defaults described in clauses (i) and (ii) in the previous sentence may be waived with the consent of the Holders of all Securities of the series then outstanding. When a Default or Event of Default is waived, it is deemed cured and not continuing, but no waiver will extend to any subsequent or other Default or impair any consequent right.

- 15 -

Section 6.05. Control by Majority . The Holders of a majority in principal amount of the Securities of a series then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee with regard to the Securities of that series or of exercising any trust or power conferred on the Trustee with regard to the Securities of that series. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of other Securityholders (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such Holders) or that would involve the Trustee in personal liability; provided , however , that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.

Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

Section 7.04. Trustee’s Disclaimer .

Section 7.05. Notice of Defaults . The Trustee will give to the Holders of the Securities of a series notice of any Default with regard to the Securities of that series actually known to a Trust Officer, within 90 days after receipt of such knowledge and in the manner and to the extent provided in TIA Section 313(c), and otherwise as provided in Section 12.03 of this Indenture;

- 21 -

provided , however , that , except in the case of a Default in the payment of the principal of, or premium, if any, or interest on any Security, the Trustee will be protected in withholding notice of the Default if and so long as it in good faith determines that the withholding of the notice is in the interests of the Holders of the Securities of the series.

Section 7.06. Reports by Trustee . Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, the Trustee will mail to each Securityholder, if any, at the name and address which appears on the registration books of the Company, and to each Securityholder who has, within the two years preceding the mailing, filed that person’s name and address with the Trustee for that purpose and each Securityholder whose name and address have been furnished to the Trustee pursuant to Section 2.07, a brief report dated as of that May 15 which complies with TIA Section 313(a). Reports to Securityholders pursuant to this Section 7.06 shall be transmitted in the manner and to the extent provided in TIA Section 313(c). The Trustee also will comply with TIA Section 313(b).

A copy of each report will at the time of its mailing to Securityholders as required be filed with each stock exchange on which Securities are listed, if any, and also with the SEC. The Company will promptly notify the Trustee in writing when the Securities of any series are listed on any stock exchange and of any delisting of Securities of any series.

Section 7.07. Compensation and Indemnity . The Company will pay to the Trustee from time to time such compensation for its services as mutually agreed to in writing. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust.

The Trustee will notify the Company promptly of any claim for which it may seek indemnity.

The Company will defend the claim, with counsel reasonably satisfactory to the Trustee, and the Trustee may have separate counsel and the Company will pay the fees and expenses of such counsel. The Company need not pay for any settlement made without its consent. The Company need not reimburse any expense or indemnify against any loss, expense or liability incurred by the Trustee to the extent it is due to the Trustee’s own willful misconduct or gross negligence (as finally adjudicated by a court of competent jurisdiction).

To secure the Company’s obligation to make payments to the Trustee under this Section 7.07, the Trustee will have a lien prior to the Securities on all money or property held or collected by the Trustee, other than money or property held in trust to pay principal or interest on particular Securities. Those obligations of the Company will survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee.

When the Trustee incurs expenses or renders services after an Event of Default specified in clause (d) or (e) of Section 6.01 occurs, the expenses and the compensation for the services of the Trustee are intended to constitute expenses of administration under any Bankruptcy Law.

For purposes of this Section 7.07, “Trustee” will include any predecessor Trustee, but the willful misconduct or gross negligence or bad faith of any Trustee will not affect the rights of any other Trustee under this Section 7.07.

Section 7.08. Replacement of Trustee . The Trustee may resign at any time by so notifying the Company. The Holders of a majority in aggregate principal amount of the Securities of all series then outstanding may remove the Trustee by so notifying the Trustee and the Company and may appoint a successor Trustee. The Company may remove the Trustee if:

(a) the Trustee fails to comply with Section 7.10;

(b) the Trustee is adjudged bankrupt or insolvent or an order for relief is entered with respect to the Trustee under any bankruptcy law;

(d) the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of Securities of all series then outstanding may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

No removal or appointment of a Trustee will be valid if that removal or appointment would conflict with any law applicable to the Company.

A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee will, subject to the lien provided for in Section 7.07, transfer all property held by it as a Trustee to the successor Trustee, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture and all Supplemental Indentures. A successor Trustee will mail notice of its succession to each Securityholder.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the resigning Trustee, Company or the Holders of a majority in aggregate principal amount of Securities of all series then outstanding may petition any court of competent jurisdiction, at the expense of the Company, for the appointment of a successor Trustee.

- 23 -

If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 will continue for the benefit of the retiring Trustee.

Section 7.09. Successor Trustee by Merger, Etc . If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust assets to, another Person, the resulting, surviving or transferee Person will, without any further act, be the successor Trustee.

If at the time a successor by merger, conversion or consolidation to the Trustee succeeds to the trusts created by this Indenture any of the Securities have been authenticated but not delivered, the successor to the Trustee may adopt the certificate of authentication of the predecessor Trustee, and deliver the Securities which were authenticated by the predecessor Trustee; and if at that time any of the Securities have not been authenticated, the successor to the Trustee may authenticate those Securities in its own name as the successor to the Trustee; and in either case the certificates of authentication will have the full force provided in this Indenture for certificates of authentication.

Section 7.10. Eligibility; Disqualification . The Trustee will at all times satisfy the requirements of TIA Section 310(a). The Trustee will at all times have (or shall be a member of a bank holding company system whose parent corporation has) a combined capital and surplus of at least $50,000,000 as set forth in its most recently published annual report of condition, which will be deemed for this paragraph to be its combined capital and surplus. The Trustee will comply with TIA Section 310(b).

Section 7.11. Preferential Collection of Claims . The Trustee will comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed will be subject to TIA Section 311(a) to the extent indicated.

(3) the last date on which a Holder of Securities may exercise the purchase right pursuant to this Article 3;

(4) the Fundamental Change Purchase Price;

(5) the Fundamental Change Purchase Date;

(6) the name and address of the Paying Agent and the Conversion Agent, if applicable;

(7) the applicable Conversion Rate and any adjustments to the applicable Conversion Rate;

(8) that the Securities with respect to which a Fundamental Change Purchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with the Indenture;

(9) that the Holder shall have the right to withdraw any Securities surrendered for purchase prior to the Fundamental Change Expiration Time; and

(10) the procedures that Holders must follow to require the Company to purchase their Securities.

No failure of the Company to give the foregoing notices and no defect therein shall limit the purchase rights of the Holders of Securities or affect the validity of the proceedings for the purchase of the Securities pursuant to this Section 3.02.

(c) Notwithstanding the foregoing, there shall be no purchase of any Securities pursuant to this Section 3.02 if the principal amount of the Securities has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date (except in the case of an acceleration resulting from a Default by the Company

in the payment of the Fundamental Change Purchase Price with respect to such Securities). The Paying Agent will promptly return to the respective Holders thereof any Physical Securities held by it during the acceleration of the Securities (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Securities) and shall deem to be cancelled any instructions for book-entry transfer of the Securities in compliance with the procedures of the Depository, in which case, upon such return or cancellation, as the case may be, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

(d) Notwithstanding the other provisions of this Article 3, the Company will not be required to make an offer to purchase the Securities upon a Fundamental Change if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements in the Indenture and such third party purchases all Securities properly tendered and not validly withdrawn under its offer.

Section 3.03 Effect of Fundamental Change Purchase Notice. Upon receipt by the Paying Agent of a Fundamental Change Purchase Notice specified in Section 3.02, the Holder of the Security in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.04) thereafter be entitled to receive solely the Fundamental Change Purchase Price in cash with respect to such Security (and any previously accrued and unpaid interest on such Security). Such Fundamental Change Purchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on the later of (x) the applicable Fundamental Change Purchase Date (provided the conditions in Section 3.02 have been satisfied) and (y) the time of delivery or book-entry transfer of such Security to the Paying Agent by the Holder thereof in the manner required by Section 3.02, subject in each case to extensions to comply with applicable law.

Section 3.04 Withdrawal of Fundamental Change Purchase Notice. A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the Fundamental Change Expiration Time, specifying:

(1) the principal amount of the Securities with respect to which such notice of withdrawal is being submitted;

(2) if Physical Securities have been issued, the certificate numbers of the withdrawn Securities; and

(3) the principal amount, if any, of each Security that remains subject to the Fundamental Change Purchase Notice, which must be such that the principal amount not to be purchased equals $1,000 or an integral multiple of $1,000 in excess thereof;

provided , however , that if the Securities are Global Securities, the notice must comply with Applicable Procedures of the Depository.

The Paying Agent will promptly return to the respective Holders thereof any Physical Securities with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with the provisions of this Section 3.04.

Section 3.05 Deposit of Fundamental Change Purchase Price. Prior to 10:00 a.m., New York City time, on the Fundamental Change Purchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the Securities or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. If the Paying Agent holds cash sufficient to pay the Fundamental Change Purchase Price of the Securities for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with the Indenture on the Fundamental Change Purchase Date, then as of such Fundamental Change Purchase Date, (a) such Securities will cease to be Outstanding and interest will cease to accrue thereon (whether or not book-entry transfer of such Securities is made or such Securities have been delivered to the Paying Agent) and (b) all other rights of the Holders in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery or book-entry transfer of such Securities).

Section 3.06 Securities Purchased in Whole or in Part. Any Security that is to be purchased, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires in the case of Physical Securities, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased.

Section 3.07 Covenant To Comply with Applicable Laws upon Purchase of Securities. In connection with any offer to purchase Securities under Section 3.02, the Company shall, in each case if required by law, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or any other required schedule under the Exchange Act and (iii) otherwise comply with all federal and state securities laws applicable to the Company in connection with such purchase offer, in each case, so as to permit the rights and obligations under Section 3.02 to be exercised in the time and in the manner specified in Section 3.02.

Section 3.08 Repayment to the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.05 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof that the Company is obligated to purchase as of the Fundamental Change Purchase Date, then, following the Fundamental Change Purchase Date, the Paying Agent shall promptly return any such excess to the Company.

ARTICLE 4

CONVERSION

Section 4.01 Right To Convert. (a) Upon compliance with the provisions of the Indenture, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date, unless such securities have been redeemed in accordance with Sections 3.02, 11.01(a) or 11.01(b), or repurchased by the Company, the Holder of any Securities not previously repurchased or redeemed shall have the right, at such

Holder’s option, to convert its Securities, or any portion thereof which is a multiple of $1,000, into Common Stock, as provided in Section 4.03, by surrender of such Securities so to be converted in whole or in part, together with any required funds, under the circumstances and in the manner described in this Article 4.

(b) Notwithstanding any other provision of the Securities or the Indenture, no Holder of Securities will be entitled to receive Common Stock following conversion of such Securities to the extent that receipt of such Common Stock would cause such Holder (either directly or after application of certain constructive ownership rules) to exceed the ownership limits contained in the Company’s charter. Any purported delivery of shares of Common Stock upon conversion of Securities shall be void and have no effect to the extent (but only to the extent) that such delivery would result in the converting holder violating the restrictions on ownership and transfer of the Common Stock contained in the Company’s charter. Any attempted conversion of Securities that would result in the issuance of shares of Common Stock in violation of these charter restrictions shall be void to the extent of the number of shares of Common Stock that would cause such violation, and the related Securities, or portions, thereof shall be returned to the Holder as promptly as practical. The Company shall not have any further obligation to the Holder with respect to such voided conversion and such Securities shall be treated as if they had not been submitted for conversion.

(c) A Security in respect of which a Holder has delivered a Fundamental Change Purchase Notice exercising such Holder’s right to require the Company to purchase such Security pursuant to Section 3.02 may be converted only if such Fundamental Change Purchase Notice is properly withdrawn in accordance with, and within the time periods set forth in, Section 3.04.

(d) If the Company delivers a Redemption Notice, (a) a Holder may convert all or any portion of its Securities called for REIT Redemption or Optional Redemption, as applicable, on or after the date of such Redemption Notice at any time prior to the Close of Business on the Business Day immediately preceding the Redemption Date and (b) in the event of an Optional Redemption, if the Conversion Date falls prior to the Regular Record Date immediately preceding the Maturity Date, such Holder shall receive, in addition to the Conversion Price due upon conversion of such Securities and accrued and unpaid interest to (but excluding) the Conversion Date, the Make-Whole Premium.

Section 4.02 Conversion Procedures.

(a) Each Security shall be convertible at the office of the Conversion Agent and, if applicable, in accordance with the Applicable Procedures of the Depository.

(b) To exercise the conversion privilege with respect to a beneficial interest in a Global Security, the Holder must complete the appropriate instruction form for conversion pursuant to the Depository’s book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or the Conversion Agent, and pay the funds, if any, required by Section 4.02(f) and any taxes or duties if required pursuant to Section 4.02(h), and the Conversion Agent must be informed of the conversion in accordance with the customary practice of the Depository.

To exercise the conversion privilege with respect to any Physical Securities, the Holder of such Physical Securities shall:

(1) complete and manually sign a conversion notice in the form set forth in the Form of Notice of Conversion (the “ Conversion Notice ”) or a facsimile of the Conversion Notice;

(2) deliver the Conversion Notice, which is irrevocable, and the Security to the Conversion Agent;

(3) if required, furnish appropriate endorsements and transfer documents,

(4) if required, make any payment required under Section 4.02(f); and

(5) if required, pay all transfer or similar taxes as set forth in Section 4.02(g).

If, upon conversion of a Security, any shares of Common Stock are to be issued to a person other than the Holder of such Security, the related Conversion Notice shall include such other person’s name and address.

If a Security is subject to a Fundamental Change Purchase Notice, such Security may not be converted unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.04 hereof prior to the relevant Fundamental Change Expiration Time.

For any Security, the first Business Day on which the Holder of such Security satisfies all of the applicable requirements set forth above with respect to such Security and on which conversion of such Security is not otherwise prohibited under the Indenture shall be the “ Conversion Date ” with respect to such Security.

Each conversion shall be deemed to have been effected as to any such Securities (or portion thereof) surrendered for conversion at the Close of Business on the applicable Conversion Date, and the person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the Close of Business on such Conversion Date.

(c) Endorsement . Any Securities surrendered for conversion shall, unless shares of Common Stock issuable on conversion are to be issued in the same name as the registration of such Securities, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or its duly authorized attorney.

(d) Physical Securities . If any Securities in a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Securities so surrendered, without charge, new Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities.

(e) Global Securities . Upon the conversion of a beneficial interest in Global Securities, the Conversion Agent shall make a notation in its records as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Securities effected through any Conversion Agent other than the Trustee.

(f) Interest Due Upon Conversion . If a Holder converts a Security after the Close of Business on a Regular Record Date but prior to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, such Holder must accompany such Security with an amount of cash equal to the amount of interest that will payable on such Security on the corresponding Interest Payment Date; provided, however , that a Holder need not make such payment (1) if the Conversion Date follows the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Redemption Date that occurs following a Regular Record Date but occurs on or prior to the corresponding Interest Payment Date; (3) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date and the Holder converts its Security after the Close of Business on such Regular Record Date and on or prior to the Open of Business on such Interest Payment Date; or (4) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Security.

(g) If a Holder surrenders Securities for conversion following a Redemption Notice and prior to the related Redemption Date, interest shall continue to accrue until the date on which the Company delivers the consideration due in respect of such Securities, and will be payable to the Holder together with the consideration due (without duplication of any interest such Holder is otherwise entitled to by virtue of being the Holder of Securities on an applicable Regular Record Date).

(h) Taxes Due Upon Conversion . If a Holder converts a Security, the Company will pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of the Common Stock upon the conversion, unless the tax is due because the Holder requests that any shares be issued in a name other than the Holder’s name, in which case the Holder will pay that tax.

(i) Cash Payments in Lieu of Fractional Shares . No fractional shares of Common Stock or scrip certificates representing fractional shares shall be issued upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of Common Stock would be issuable upon the conversion of any Security or Securities, the Company shall make a payment therefor in cash to the Holder of Securities equal to the product of (i) such fraction of a share and (ii) the Last Reported Sale Price of the Common Stock on the relevant Scheduled Trading Day (or, if the Scheduled Trading Day is not a Trading Day, the next following Trading Day).

Section 4.03 Settlement Upon Conversion.

(a) Upon conversion of any Securities, subject to Sections 4.01, 4.02 and this Section 4.03, the Company shall satisfy its obligation upon conversion (the “ Conversion Obligation ”) by delivery of the shares (and, if applicable, payment of the cash) described under Section 4.03(b) below.

(b) Upon conversion of Securities, the Company shall deliver, in respect of each $1,000 principal amount of Securities tendered for conversion in accordance with their terms:

(1) a number of shares of Common Stock equal to (a) (i) the aggregate principal amount of Securities to be converted divided by (ii) $1,000, multiplied by (b) the applicable Conversion Rate on the date the converting Holder is treated as a record owner of the Common Stock pursuant to the last paragraph of Section 4.02(b); and

(2) an amount in cash in lieu of any fractional shares of Common Stock as provided in Section 4.02(i).

(c) Delivery of the shares of Common Stock (and, if applicable, payment of the cash) pursuant to Section 4.03(b) shall be made by the Company on or prior to the third Business Day immediately following the Conversion Date to the holder of a Security surrendered for conversion, or such holder’s nominee or nominees, and the Company shall deliver to the Conversion Agent or to such holder, or such holder’s nominee or nominees, certificates or a book-entry transfer through the Depository for the number of full shares of Common Stock to which such holder shall be entitled as part of such Conversion Obligation. Notwithstanding the foregoing, delivery of the shares of Common Stock (and, if applicable, payment of the cash) pursuant to Section 4.03(b) with respect to any Conversion Date that occurs on or after the Regular Record Date immediately preceding the Maturity Date shall be made by the Company on the Maturity Date.

(d) Settlement of Accrued Interest and Deemed Payment of Principal . If a Holder converts a Security, the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Security, and the Company’s delivery of shares of Common Stock (and cash in lieu of fractional shares, if any) into which a Security is convertible will be deemed to satisfy and discharge in full the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Security to, but excluding, the Conversion Date; provided, however , that if a Holder converts a Security after a Regular Record Date and prior to the Open of Business on the corresponding Interest Payment Date, the Company will still be obligated to pay the interest due on such Interest Payment Date to the Holder of such Security on such Regular Record Date (provided the Holder makes the interest payment upon conversion if so required by Section 4.02(f)).

As a result, except as otherwise provided in the proviso to the immediately preceding sentence, any accrued and unpaid interest with respect to a converted Security will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In no event will a Holder be entitled to receive any dividend or other distribution with respect to any Common Stock issued on conversion of such Holder’s Securities if the applicable Conversion Date is after the Regular Record Date for such dividend or distribution.

(e) Notices . Whenever a Conversion Date occurs with respect to a Security, the Conversion Agent will, as promptly as possible, and in no event later than the Business Day immediately following such Conversion Date, deliver to the Company and the Trustee, if it is not then the Conversion Agent, notice that a Conversion Date has occurred, which notice will state such Conversion Date, the principal amount of Securities converted on such Conversion Date and the names of the Holders that converted Securities on such Conversion Date.

Section 4.04 Adjustment of Conversion Rate.

The Conversion Rate will be adjusted as described in this Section 4.04, except that the Company shall not make any adjustment to the Conversion Rate if Holders participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and as a result of holding the Securities, in any of the transactions described below without

having to convert their Securities, as if they held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Securities held by such Holder.

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on all or substantially all outstanding shares of the Common Stock, or if the Company effects a share split or share combination, the Conversion Rate will be adjusted based on the following formula:


CR ₁	=	CR ₀	x	OS ₁
				OS ₀

where,


CR ₀	=	the Conversion Rate in effect immediately prior to the Close of Business on the record date of such dividend or distribution, or immediately prior to the Open of Business on the effective date of such share split or share combination, as applicable;

CR ₁	=	the Conversion Rate in effect immediately after the Close of Business on such record date or immediately after the Open of Business on such effective date;

OS ₀	=	the number of shares of Common Stock outstanding immediately prior to the Close of Business on such record date or immediately prior to the Open of Business on such effective date, as applicable, before giving effect to such dividend, distribution, share split or share combination; and

OS ₁	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination, as applicable.

Any adjustment made pursuant to this Section 4.04(a) shall become effective immediately after the Close of Business on the record date for such dividend or distribution, or immediately after the Open of Business on the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 4.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company issues to all or substantially all holders of the outstanding Common Stock any rights, options or warrants entitling them, for a period of not more than forty-five (45) calendar days after the record date of such issuance, to subscribe for or purchase shares of the Common Stock, at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate will be increased based on the following formula:


CR ₁	=	CR ₀	x	OS ₀ + X
				OS ₀ + Y

where,


CR ₀	=	the Conversion Rate in effect immediately prior to the Close of Business on the record date for such issuance;

CR ₁	=	the Conversion Rate in effect immediately after the Close of Business on such record date;

OS ₀	=	the number of shares of Common Stock outstanding immediately prior to the Close of Business on such record date;

X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and

Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

Any increase made under this Section 4.04(b) will be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the Open of Business on the record date for such issuance. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of Common Stock are not delivered upon the expiration of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, or if such rights, options or warrants are not exercised prior to their expiration, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such record date for such issuance had not occurred.

For purposes of this Section 4.04(b), in determining whether any rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of the Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the outstanding Common Stock, excluding:

(1) dividends or distributions, rights options or warrants as to which an adjustment was effected pursuant to Section 4.04(a) hereof or Section 4.04(b) hereof;

(2) dividends or distributions paid exclusively in cash; and

(3) Spin-Offs described in Section 4.04(c);

then the Conversion Rate shall be increased based on the following formula:


CR ₁	=	CR ₀	x	SP ₀
				SP ₀ – FMV

where,


CR ₀	=	the Conversion Rate in effect immediately prior to the Close of Business on the record date for such distribution;

CR ₁	=	the Conversion Rate in effect immediately after the Close of Business on such record date;

SP ₀	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV	=	the fair market value (as determined by the Board of Directors) of the shares of the Company’s Capital Stock, evidences the Company’s indebtedness, other assets, or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities distributed with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

provided that if “FMV” (as defined above) is equal to or greater than “SP ₀ ” (as defined above), then in lieu of the foregoing increase, each Holder of a Security shall receive, in respect of each $1,000 principal amount of a Security it holds, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of the Company’s Capital Stock, evidences of the Company’s indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities that such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the record date for the distribution.

Any increase made under this portion of this Section 4.04(c) will become effective immediately after the Close of Business on the record date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

With respect to an adjustment pursuant to this Section 4.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary of the Company or other business unit of the Company, and such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon the consummation of the distribution) on a United States national securities exchange (a “ Spin-Off ”), the Conversion Rate will be increased based on the following formula:


CR ₁	=	CR ₀	x	FMV ₀ + MP ₀
				MP ₀

where,


CR ₀	=	the Conversion Rate in effect immediately prior to the Close of Business on the record date for such Spin-Off;

CR ₁	=	the Conversion Rate in effect immediately after the Close of Business on the record date for such Spin-Off;

FMV ₀	=	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of outstanding Common Stock applicable to one share of Common Stock over the first ten consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “ Valuation Period ”); and

MP ₀	=	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.

The adjustment to the applicable Conversion Rate under the preceding paragraph of this Section 4.04(c) will be made immediately after the Open of Business on the day after the last Trading Day of the Valuation Period, but will be given effect as of the Open of Business on the record date for the Spin-Off. For purposes of determining the applicable Conversion Rate, in respect of any conversion during the ten Trading Days commencing on the Ex-Dividend Date for any Spin-Off, references within the portion of this Section 4.04(c) related to “Spin-Offs” to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the relevant Conversion Date.

For purposes of the second adjustment set forth in this Section 4.04(c), (i) the Last Reported Sale Price of any Capital Stock or similar equity interest shall be calculated in a manner analogous to that used to calculate the Last Reported Sale Price of the Common Stock in the definition of “Last Reported Sale Price” set forth in Section 1.01 hereof, (ii) whether a day is a Trading Day (and whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for such Capital Stock or similar equity interest shall be determined in a manner analogous to that used to determine whether a day is a Trading Day (or whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for the Common Stock, and (iii) whether a day is a Trading Day to be included in a Valuation Period will be determined based on whether a day is a Trading Day for both the Common Stock and such Capital Stock or similar equity interest.

Subject to Section 4.04(f), for the purposes of this Section 4.04(c), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (a “ Trigger Event ”): (1) are deemed to be transferred with such shares of Common Stock; (2) are not exercisable; and (3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.04(c), (and no adjustment to the Conversion Rate under this Section 4.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or

warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 4.04(c). If any such right, option or warrant, distributed prior to the Issue Date is subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date of such deemed distribution (in which case the original rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 4.04(c) was made, (1) in the case of any such rights, options or warrants which shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by holders of Common Stock with respect to such rights, options or warrants (assuming each such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

For purposes of Section 4.04(a) hereof, Section 4.04(b) hereof and this Section 4.04(c), if any dividend or distribution to which this Section 4.04(c) applies includes one or both of:

(1) a dividend or distribution of shares of Common Stock to which Section 4.04(a) hereof also applies (the “ Clause A Distribution ”); or

(2) a dividend or distribution of rights, options or warrants to which Section 4.04(b) hereof also applies (the “ Clause B Distribution ”),

then (i) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 4.04(c) applies (the “ Clause C Distribution ”) and any Conversion Rate adjustment required to be made under this Section 4.04(c) with respect to such Clause C Distribution shall be made, (ii) the Clause B Distribution, if any, shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 4.04(b) hereof with respect thereto shall then be made, except that, if determined by the Company, (A) the “record date” of the Clause B Distribution and the Clause A Distribution, if any, shall be deemed to be the record date of the Clause C Distribution and (B) any shares of Common Stock included in the Clause A Distribution or the Clause B Distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such record date” within the meaning of Section 4.04(b) hereof, and (iii) the Clause A Distribution, if any, shall be deemed to immediately follow the Clause C Distribution or the Clause B Distribution, as the case may be, except that, if determined by the Company, (A) the “record date” of the Clause A Distribution and the Clause B Distribution, if any, shall be deemed to be the record date of the Clause C Distribution, and (B) any shares of Common Stock included in the Clause A distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such record date or such effective date” within the meaning of Section 4.04(a) hereof.

(d) If any cash dividend or distribution is made to all or substantially all holders of the outstanding Common Stock to the extent that the aggregate of all such cash dividends or distributions paid in any quarter exceeds the dividends threshold amount (the “ DTA ”) for such quarter, the Conversion Rate shall be adjusted based on the following formula:


CR ₁	=	CR ₀	x	SP ₀ - DTA
				SP ₀ - C

where,


CR ₀	=	the Conversion Rate in effect immediately prior to the Close of Business on the record date for such dividend or distribution;

CR ₁	=	the Conversion Rate in effect immediately after the Close of Business on the record date for such dividend or distribution;

SP ₀	=	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;

DTA	=	the dividend threshold amount, which shall initially be $0.33 per quarter provided, however , that the DTA with respect to any date shall be reduced by the aggregate per share cash dividends or distributions that were paid to all or substantially all holders of the outstanding Common Stock during the applicable dividend period prior to such payment and provided further that if the result of such reduction is a negative number, the DTA shall be deemed to be zero; and

C	=	the amount in cash per share that the Company distributes to holders of the outstanding Common Stock.

The DTA is subject to adjustment on an inversely proportional basis whenever the Conversion Rate is adjusted, other than adjustments made pursuant to this Section 4.04(d).

If “C” (as defined above) is equal to or greater than “SP ₀ ” (as defined above), in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Securities it holds, at the same time and upon the same terms as holders of shares of the outstanding Common Stock, the amount of cash that such Holder would have received if such Holder had owned a number of shares of Common Stock equal to the Conversion Rate on the record date for such cash dividend or distribution. Such increase shall become effective immediately after the Close of Business on the record date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender offer or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the

Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “ Offer Expiration Date ”), the Conversion Rate shall be increased based on the following formula:


CR ₁	=	CR ₀	x	AC + (SP ₁ x OS ₁ )
				OS ₀ x SP ₁

where,


CR ₀	=	the Conversion Rate in effect immediately prior to the Close of Business on the Offer Expiration Date;

CR ₁	=	the Conversion Rate in effect immediately after the Close of Business on the Offer Expiration Date;

AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender offer or exchange offer;

OS ₀	=	the number of shares of Common Stock outstanding immediately prior to the expiration time of the tender or exchange offer on the Offer Expiration Date (prior to giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer);

OS ₁	=	the number of shares of Common Stock outstanding immediately after the expiration time of the tender or exchange offer on the Offer Expiration Date (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer); and

SP ₁	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Offer Expiration Date.

The adjustment to the applicable Conversion Rate under the preceding paragraph of this Section 4.04(e) will be given effect at the Open of Business on the Trading Day next succeeding the Offer Expiration Date. For purposes of determining the applicable Conversion Rate, in respect of any conversion during the ten Trading Days commencing on the Trading Day next succeeding the Offer Expiration Date, references within this Section 4.04(e) to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, and including, the relevant Conversion Date.

(f) Poison Pill . Whenever a Holder converts a Security, to the extent that the Company has a rights plan in effect, the Holder converting such Security will receive, in addition to any shares of Common Stock otherwise received in connection with such conversion, the rights under the rights plan unless, prior to conversion the rights have expired, terminated or been redeemed or unless the rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted at the time of separation (and not at the time of the issuance of the rights) as if the Company distributed to all holders of the Common Stock, shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants as described in Section 4.04(c) hereof, subject to readjustment in the event of the expiration, termination or redemption of such rights.

(g) Limitation on Adjustments . Except as stated in this Section 4.04, the Company will not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. If, however, the application of the formulas in Sections 4.04(a) through (e) hereof would result in a decrease in the Conversion Rate, then, except to the extent of any readjustment to the Conversion Rate, no adjustment to the Conversion Rate will be made (other than as a result of a reverse share split, share combination or readjustment).

In addition, notwithstanding anything to the contrary herein, the Conversion Rate will not be adjusted:

(1) on account of stock repurchases that are not tender offers referred to in Section 4.04(e) hereof, including structured or derivative transactions, or transactions pursuant to a stock repurchase program approved by the Board of Directors or otherwise;

(2) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(3) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan, program or agreement (including issuances to the personnel of the Company’s external manager pursuant to any such plan, program or agreement) of or assumed by the Company or any of its Subsidiaries;

(4) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in the preceding clause (3) and outstanding as of the date the Securities were first issued;

(5) for a change in the par value of the Common Stock;

(6) for accrued and unpaid interest on the Securities, if any; or

(7) for an event otherwise requiring an adjustment under the Indenture if such event is not consummated.

(h) For purposes of this Section 4.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

(i) Withholding on Adjustments . If, in connection with any adjustment to the Conversion Rate as set forth in this Section 4.04 a Holder shall be deemed for U.S. federal tax purposes to have received a distribution, the Company may set off any withholding tax it reasonably believes it is required to collect with respect to any such deemed distribution

against cash payments of interest in accordance with the provisions of Section 2.04 hereof or from cash and Common Stock, if any, otherwise deliverable to a Holder upon a conversion of Securities in accordance with the provisions of Section 4.03 hereof, a repurchase of a Security in accordance with the provisions of Article 3 hereof or a redemption of a Security in accordance with the provisions of Article 11 hereof.

Section 4.05 Adjustments of Prices and Voluntary Adjustments.

(a) Adjustments of Prices . Whenever any provision of the Indenture requires the Company to calculate the Last Reported Sale Prices or any function thereof over a span of multiple days, the Company will make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Effective Date, Record Date or Offer Expiration Date of the event occurs, at any time during the period when such Last Reported Sale Prices or function thereof is to be calculated.

(b) Voluntary Adjustments . To the extent permitted by applicable law and the rules of the New York Stock Exchange or any other securities exchange or market on which the Common Stock is then listed, the Company is permitted to increase the Conversion Rate of the Securities by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. The Company may also (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event.

Section 4.06 Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change.

(a) Increase in the Conversion Rate . If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Securities in connection with such Make-Whole Fundamental Change, the Company shall, under certain circumstances, increase the Conversion Rate for the Securities so surrendered for conversion by a number of additional shares of Common Stock (the “ Additional Shares ”), as described in this Section 4.06. A conversion of Securities shall be deemed for these purposes to be “in connection with” a Make-Whole Fundamental Change if the relevant Conversion Notice is received by the Conversion Agent during the period from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Close of Business on the Business Day immediately prior to the related Fundamental Change Purchase Date or, if such Make-Whole Fundamental Change is not a Fundamental Change, the 35th Business Day immediately following the Effective Date for such Make-Whole Fundamental Change.

(b) Determining the Number of Additional Shares . The number of Additional Shares, if any, by which the Conversion Rate will be increased for a Holder that converts its Securities in connection with a Make-Whole Fundamental Change shall be determined by reference to the table attached as Schedule A hereto, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “ Effective Date ”) and the price (the “ Stock Price ”) paid (or deemed paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

(c) Interpolation and Limits . The exact Stock Prices and Effective Dates may not be set forth in the table in Schedule A, in which case:

(1) If the Stock Price is between two Stock Prices in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year.

(2) If the Stock Price is greater than $40.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to Section 4.06(d)(4) hereof), the Conversion Rate shall not be increased.

(3) If the Stock Price is less than $22.70 per share (subject to adjustments in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to Section 4.06(d)(4) hereof), the Conversion Rate shall not be increased.

Notwithstanding the foregoing, in no event will the Conversion Rate be increased on account of a Make-Whole Fundamental Change to exceed 45.0528 shares of Common Stock per $1,000 principal amount of Securities, subject to adjustments in the same manner as the Conversion Rate is required to be adjusted as set forth in Section 4.04 hereof.

(4) The Stock Prices set forth in the column headings of the table in Schedule A hereto shall be adjusted as of any date on which the Conversion Rate of the Securities is otherwise required to be adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in such table shall be adjusted in the same manner and at the same time as the Conversion Rate is required to be adjusted as set forth in Section 4.04.

(d) Notices . The Company shall notify the Trustee and the Holders of the Effective Date of any Make Whole Fundamental Change announcing such Effective Date no later than five Business Days after such Effective Date. Such notice shall be sent by first class mail or, in the case of any Global Securities, in accordance with the procedures of the Depository for providing notices. Simultaneously with providing such notice, the Company shall publish this information in a newspaper of general circulation in The City of New York or publish the information on the Company’s website or through such other public medium as the Company may use at that time.

Section 4.07 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale.

(a) Merger Events . In the case of:

(1) any recapitalization, reclassification or change of the outstanding Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a split, subdivision or combination for which an adjustment was made pursuant to Section 4.04(a) hereof);

(2) any consolidation, merger or combination involving the Company;

(3) any sale, lease or other transfer to a third party of the consolidated assets of the Company and its Subsidiaries substantially as an entirety; or

(4) any statutory share exchange;

and, in each case, as a result of which the outstanding Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “ Merger Event ,” any such stock, other securities, other property or assets, “ Reference Property ,” and the amount of kind of Reference Property that a holder of one share of Common Stock (i) is entitled to receive in the applicable Merger Event or (ii) if as a result of the applicable Merger Event, each share of Common Stock is converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the per-share of Common Stock weighted average of the types and amounts of Reference Property received by the holders of Common Stock that affirmatively make such an election, a “ Unit of Reference Property ”) then, at the effective time of such Merger Event, the right to convert each $1,000 principal amount of Securities into a number of shares of the Common Stock equal to the applicable Conversion Rate will, without the consent of the Holders, be changed into a right to convert each $1,000 principal amount of Securities into a number of Units of Reference Property equal to the applicable Conversion Rate and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture) providing for such change in the right to convert each $1,000 principal amount of Securities. With respect to any such Reference Property, the Last Reported Sale Price will, to the extent reasonably possible, be calculated based on the value of a Unit of Reference Property and the definitions of Trading Day and Market Disruption Event shall be determined by reference to the components of a Unit of Reference Property.

If the Merger Event causes the outstanding Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election) as contemplated by the preceding paragraph such that a Unit of Reference Property is comprised of the per-share of Common Stock weighted average of the types and amounts of consideration received by the holders of the Common Stock in the Merger Event that affirmatively make such an election, the Company shall notify Holders of the weighted average as soon as practicable after such determination is made.

The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 4.07. Such supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments which shall be as nearly equivalent to the adjustments provided for in this Article 4 in the judgment of the Board of Directors or the board of directors of the successor Person. If, in the case of any such Merger Event, the Reference Property receivable thereupon by a holder of Common Stock includes

shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing Person, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary.

(b) Notice of Supplemental Indentures . The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Securities maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section 4.07 shall similarly apply to successive Merger Events and the provisions of this Section 4.07 and Article IX of the Base Indenture (as modified by Article 8 of this Supplemental Indenture) shall apply to any such successive Merger Events.

Section 4.08 Stock Issued Upon Conversion.

(a) Reservation of Shares . To the extent necessary to satisfy its obligations under the Indenture, prior to issuing any shares of Common Stock, the Company will reserve out of its authorized but unissued shares of Common Stock a sufficient number of shares of Common Stock to permit the conversion of the Securities.

(b) Certain other Covenants . The Company covenants that all shares of Common Stock that may be issued upon conversion of Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge (other than those created by the Holder or due to a change in registered owner).

(c) Stock Transfer Agent . American Stock Transfer & Trust Company is, as of the date of the this Supplemental Indenture, the Stock Transfer Agent for the Common Stock and the Company shall notify the Trustee if the Stock Transfer Agent for the Common Stock is changed. The Company and the Trustee (as Conversion Agent) agree to cooperate with the Stock Transfer Agent for the Common Stock in connection with any conversions of the Securities.

The Company shall list or cause to have quoted any shares of Common Stock to be issued upon conversion of Securities on each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted.

Section 4.09 Responsibility of Trustee. The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine or calculate the Conversion Rate (or any adjustments thereto), to determine whether any facts exist which may require any adjustment of the Conversion Rate, or to confirm the accuracy of any such adjustment when made or the appropriateness of the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock or of any other securities or property that may at any time be issued or delivered upon the conversion of any Securities; and the Trustee and the Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Securities for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this

Article 4. The rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation its right to be compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its capacity as Conversion Agent.

Section 4.10 Notice to Holders.

(a) Notice to Holders Prior to Certain Actions . The Company shall deliver notices of the events specified below at the times specified below and containing the information specified below unless, in each case, (i) pursuant to the Indenture, the Company is already required to deliver notice of such event containing at least the information specified below at an earlier time or, (ii) the Company, at the time it is required to deliver a notice, does not have knowledge of all of the information required to be included in such notice, in which case, the Company shall (A) deliver notice at such time containing only the information that it has knowledge of at such time (if it has knowledge of any such information at such time), and (B) promptly upon obtaining knowledge of any such information not already included in a notice delivered by the Company, deliver notice to each Holder containing such information. In each case, the failure by the Company to give such notice, or any defect therein, shall not affect the legality or validity of such event. Any notices sent to Holders shall also be sent to the Trustee.

(b) Issuances, Distributions, and Dividends and Distributions . If the Company (A) announces any issuance of any rights, options or warrants that would require an adjustment in the Conversion Rate pursuant to Section 4.04(b) hereof; (B) authorizes any distribution that would require an adjustment in the Conversion Rate pursuant to Section 4.04(c) hereof (including any separation of rights from the Common Stock described in Section 4.04(g) hereof); or (C) announces any dividend or distribution that would require an adjustment in the Conversion Rate pursuant to Section 4.04(d) hereof, then the Company shall deliver to the Holders, as promptly as possible, but in any event at least 15 calendar days prior to the applicable record date, notice describing such issuance, distribution, dividend or distribution, as the case may be, and stating the expected Ex-Dividend Date and record date for such issuance, distribution, dividend or distribution, as the case may be. In addition, the Company shall deliver to the Holders notice if the consideration included in such issuance, distribution, dividend or distribution, or the Ex-Dividend Date or record date of such issuance, distribution, dividend or distribution, as the case may be, changes.

(c) Voluntary Increases . If the Company increases the Conversion Rate pursuant to Section 4.05(b), the Company shall deliver notice to the Holders at least 15 calendar days prior to the date on which such increase will become effective, which notice shall state the date on which such increase will become effective and the amount by which the Conversion Rate will be increased.

(d) Dissolutions, Liquidations and Winding-Ups . If there is a voluntary or involuntary dissolution, liquidation or winding-up of the Company, the Company shall deliver notice to the Holders at promptly as possible, but in any event at least 15 calendar days prior to the earlier of (i) the date on which such dissolution, liquidation or winding-up, as the case may be, is expected to become effective or occur, and (ii) the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such dissolution, liquidation or winding-up, as the case may be, which notice shall state the expected effective date and record date for such event, as applicable, and the amount and kind of property that a holder of

one share of the Common Stock is expected to be entitled, or may elect, to receive in such event. The Company shall deliver an additional notice to Holders, as promptly as practicable, whenever the expected effective date or record date, as applicable, or the amount and kind of property that a holder of one share of the Common Stock is expect to be entitled to receive in such event, changes.

(e) Notices After Certain Actions and Events . Whenever an adjustment to the Conversion Rate becomes effective pursuant to Sections 4.04, 4.05 or 4.06 hereof, the Company will (i) file with the Trustee an Officers’ Certificate stating that such adjustment has become effective, the Conversion Rate, and the manner in which the adjustment was computed and (ii) deliver notice to the Holders stating that such adjustment has become effective and the Conversion Rate or conversion privilege as adjusted. Failure to give any such notice, or any defect therein, shall not affect the validity of any such adjustment.

(g) failure by the Company to pay beyond any applicable grace period, or the acceleration of, indebtedness (other than Non-Recourse Indebtedness) of the Company or any of the Company’s Subsidiaries in an aggregate principal amount with respect to which the default has occurred is greater than $10,000,000 (or its foreign currency equivalent at the time);

(h) the Company or any Significant Subsidiary of the Company shall commence a voluntary case or other proceeding seeking the liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant Subsidiary of the Company or any substantial part of the Company’s or such Significant Subsidiary of the Company’s property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or

Section 6.03 Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.02(h) or Section 6.02(i)), unless the principal of all of the Securities shall have already become due and payable, either the Trustee or the holders of at least 25% in aggregate principal amount of the Securities then Outstanding, by notice in writing to the Company (and to the Trustee if given by the Holders), may declare 100% of the principal of, and accrued and unpaid interest, if any, on all the Securities to be due and payable immediately. If an Event of Default specified in Section 6.02(h) or Section 6.02(i) occurs and is continuing, the principal of, and accrued and unpaid interest, if any, on all Securities shall be immediately due and payable.

Section 6.04 Supplementary Interest.

(a) Notwithstanding any provisions of the Indenture to the contrary, if the Company so elects, the sole remedy for an Event of Default relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the TIA any documents or

reports that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, or (ii) the Company’s failure to comply with Section 5.06 hereof (a “ Reporting Event of Default ”), will consist exclusively of the right to receive additional interest on the Securities (the “ Supplementary Interest ”) at a rate per year equal to 0.50% per annum of the Outstanding principal amount of the Securities for each day during such 180-day period as long as such Event of Default is continuing (and neither waived nor cured). If the Company so elects, such Supplementary Interest will be payable in the same manner and on the same dates as the stated interest payable on the Securities. On the 181st day after such Event of Default (if the Reporting Event of Default is not cured or waived prior to such 181st day), the Securities will be subject to acceleration pursuant to Section 6.03. The provisions of this Section 6.04 will not affect the rights of Holders of Securities in the event of the occurrence of any Event of Default that is not a Reporting Event of Default. In the event the Company does not elect to pay the Supplementary Interest following an Event of Default in accordance with this Section 6.04 or the Company elects to make such payment but does not pay the Supplementary Interest when due, the Securities will be immediately subject to acceleration as provided in Section 6.03.

(b) In order to elect to pay the Supplementary Interest as the sole remedy during the first 180 days after the occurrence of a Reporting Event of Default, the Company must notify all Holders of Securities, the Trustee and the Paying Agent of such election prior to the beginning of such 180-day period. Upon the Company’s failure to timely give such notice, the Securities will be immediately subject to acceleration as provided in Section 6.03.

Section 6.05 Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Securities then Outstanding, by written notice to the Company and to the Trustee, may waive (including by way of consents obtained in connection with a repurchase of, or tender or exchange offer for, the Securities) all past Defaults or Events of Default with respect to the Securities (other than a Default or an Event of Default resulting from nonpayment of principal or interest, a failure to deliver consideration due upon conversion or any other provisions that requires the consent of each affected Holder to amend) and rescind any such acceleration with respect to the Securities and its consequences if (i) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default, other than the nonpayment of the principal of, and interest on, the Securities that have become due solely by such declaration of acceleration have been cured or waived.

Section 6.06 Control by Majority. At anytime, the Holders of a majority of the aggregate principal amount of the then Outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or for exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture or, subject to the Trustee’s duties under Article VII of the Base Indenture and the TIA, that the Trustee determines to be unduly prejudicial (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial) to the rights of a Holder or to the Trustee, or that would potentially involve the Trustee in personal liability unless the Trustee is offered indemnity and/or security satisfactory to it against any loss, liability or expense to the Trustee that may result from the Trustee’s instituting such proceeding as the Trustee. Prior to taking any action hereunder, the Trustee will be entitled to indemnification and/or security satisfactory to it against all losses and expenses caused by taking or not taking such action.

Section 6.07 Limitation on Suits. Subject to Section 6.08 hereof, no Holder may pursue a remedy with respect to the Indenture or the Securities unless:

(a) such Holder has previously delivered to the Trustee written notice that an Event of Default is continuing;

(b) the Holders of at least 25% of the aggregate principal amount of the then Outstanding Securities request that the Trustee pursue a remedy with respect to such Event of Default;

(c) such Holder or Holders have offered and, if requested, provided to the Trustee indemnity and/or security satisfactory to the Trustee against any loss, liability or other expense of compliance with such written request;

(d) the Trustee has not complied with such request within 60 days after receipt of such written request and offer of security or indemnity; and

(e) during such 60-day period, the Holders of a majority of the aggregate principal amount of the then Outstanding Securities did not deliver to the Trustee a direction inconsistent with such request.

Section 6.08 Rights of Holders to Receive Payment and to Convert. Notwithstanding anything to the contrary elsewhere in the Indenture, the right of any Holder to receive payment of the principal of, interest on, Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, its Securities, on or after the respective due date, and to convert its Securities and receive payment or delivery of the consideration due with respect to such Securities in accordance with Article 4 hereof, or to bring suit for the enforcement of any such payment or conversion rights, will not be impaired or affected without the consent of such Holder and will not be subject to the requirements of Section 6.07 hereof.

Section 6.09 Collection of Indebtedness; Suit for Enforcement by Trustee. If an Event of Default specified in Section 6.02(a), 6.02(b) or 6.02(c) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, interest on, Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, and the consideration due upon the conversion of, the Securities, as the case may be, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, as well as any other amounts that may be due under Section 7.07 of the Base Indenture.

Section 6.10 Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under the Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered.

Section 6.11 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, will be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and, in the event that the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under the Base Indenture (including Section 7.07 of the Base Indenture) and this Supplemental Indenture. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 of the Base Indenture out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a lien on, and is paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained will be deemed to authorize the Trustee to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.12 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under the Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 6.13 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 2.09 of the Base Indenture, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.14 Delay or Omission Not a Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time and as often as may be deemed expedient by the Trustee (subject to the limitations contained in the Indenture) or by the Holders, as the case may be.

Section 6.15 Priorities. If the Trustee collects any money pursuant to this Article 6, it will pay out the money in the following order:

FIRST: to the Trustee, its agents and attorneys for amounts due under Section 7.07 of the Base Indenture and this Supplemental Indenture, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

SECOND: to the Holders, for any amounts due and unpaid on the principal of, accrued and unpaid interest on, Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, and any cash due upon conversion of, any Security, without preference or priority of any kind, according to such amounts due and payable on all of the Securities; and

THIRD: the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs.

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.15. If the Trustee so fixes a record date and a payment date, at least 15 days prior to such record date, the Company will deliver to each Holder and the Trustee a written notice, which notice will state such record date, such payment date and the amount of such payment.

Section 6.16 Undertaking for Costs. All parties to the Indenture agree, and each Holder, by such Holder’s acceptance of a Security, shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under the Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, however , that the provisions of this Section 6.16 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the Securities then Outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal of, accrued and unpaid interest, if any, on, or Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, any Security on or after the due date expressed or provided for in the Indenture or to any suit for the enforcement of the right to convert any Security in accordance with the provisions of Article 4 hereof.

Section 6.17 Waiver of Stay, Extension and Usury Laws. The Company covenants that, to the extent that it may lawfully do so, it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of the Indenture; and the Company, to the extent that it may lawfully do so, hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will instead suffer and permit the execution of every such power as though no such law has been enacted.

Section 6.18 Notices from the Trustee. Notwithstanding anything to the contrary in the Base Indenture, whenever a Default occurs and is continuing and a Responsible Officer of the Trustee has received written notice of such Default, the Trustee must deliver notice of such Default to the Holders within 90 days after the date on which such Default first occurred. Except in the case of a Default in the payment of the principal of, interest on, or Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, any Security or of a Default in the payment or delivery, as the case may be, of the consideration due upon conversion of a Security, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders.

Ladies and Gentlemen:

We have acted as counsel to Hannon Armstrong Sustainable Infrastructure Capital Inc. (the “ Company ”) in connection with the registration statement on Form S-3, as amended by Post-Effective Amendment No. 1 (File No. 333-215229) (the “ Registration Statement ”) under the Securities Act of 1933, as amended (the “ Securities Act ”). We are furnishing this letter to you in connection with the offer and sale by the Company of $135,000,000 aggregate principal amount of its 4.125% Convertible Senior Notes due 2022 (the “ Notes ”), for issuance pursuant to the Underwriting Agreement, dated August 16, 2017 (the “ Underwriting Agreement ”), by and between the Company, and Deutsche Bank Securities Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC, as representatives of the several underwriters named therein, and an Indenture, dated as of August 22, 2017, as supplemented by a First Supplemental Indenture, dated as of August 22, 2017 (together, the “ Indenture ”), each by and between the Company and U.S. Bank National Association, as trustee.

In rendering the opinions expressed below, we have examined and relied upon originals or copies, certified or otherwise identified to our satisfaction, of the Registration Statement, the Indenture, the Notes and certain resolutions of the board of directors of the Company (the “ Board of Directors ”) and of a pricing committee of the Board of Directors (the “ Pricing Committee ”), relating to the transactions contemplated by the Underwriting Agreement and other related matters.

Based on, and subject to, the foregoing, the qualifications and assumptions set forth herein and such other examination of law as we have deemed necessary, we are of the opinion that (i) following the (a) issuance of the Notes pursuant to the terms of the Underwriting Agreement and (b) receipt by the Company of the consideration for the Notes specified in the resolutions of the Board of Directors and of the Pricing Committee:

The Notes will be the valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting enforcement of creditors’ rights generally, or by general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law); and

The issuance of the shares of the Company’s common stock, par value $0.01 per share, into which the Notes are convertible (the “ Conversion Shares ”) upon conversion of the Notes pursuant to the terms of the Notes and the Indenture have been duly authorized by all necessary corporate action on the part of the Company and, if and when issued and delivered by the Company pursuant to the terms of the Notes and the Indenture upon conversion of the Notes, the Conversion Shares will be legally issued, fully paid and nonassessable.

Re: REIT Qualification of Hannon Armstrong Sustainable Infrastructure Capital, Inc.

Ladies and Gentlemen:

We have acted as counsel to Hannon Armstrong Sustainable Infrastructure Capital, Inc., a Maryland corporation (the “Company”), in connection with the offer and sale by the Company of $135,000,000 aggregate principal amount of its 4.125% Convertible Senior Notes due 2022 pursuant to the Company’s Post-Effective Amendment No. 1 to the Company’s shelf registration statement on Form S-3 (No. 333- 215229) (such Post-Effective Amendment, the “Registration Statement”) filed on August 4, 2017, and the related prospectus supplement filed on August 17, 2017 (together with any amendments thereto, the “Prospectus Supplement,” and together with the Registration Statement, the “Registration Statements”) by the Company with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended. Except as otherwise indicated, capitalized terms used in this opinion letter have the meanings given to them in the Registration Statement.

In rendering the opinions expressed herein, we have examined and, with your permission, relied on the following items:

1. the Articles of Amendment and Restatement of the Company;

2. the bylaws of the Company;

3. a Certificate of Representations, (the “Certificate of Representations”) dated as of the date hereof, provided to us by the Company;

4. the Registration Statements;

5. the private letter ruling issued by the Internal Revenue Service (the “IRS”) to the Company dated July 30, 2012 and released on June 7, 2013 (the “Ruling”); and

6. such other documents, records and instruments as we have deemed necessary in order to enable us to render the opinions referred to in this letter.

				CLIFFORD CHANCE US LLP

In our examination of the foregoing documents, we have assumed, with your consent, that (i) all documents reviewed by us are original documents, or true and accurate copies of original documents and have not been subsequently amended, (ii) the signatures of each original document are genuine, (iii) all factual representations and statements set forth in such documents are true and correct, (iv) all obligations imposed by any such documents on the parties thereto have been performed or satisfied in accordance with their terms, and (v) the Company at all times will operate in accordance with the method of operation described in its organizational documents, the Registration Statements and the Certificate of Representations. As of the date hereof, we are not aware of any facts inconsistent with the statements in the organizational documents, the Registration Statements or the Certificate of Representations.

For purposes of rendering the opinions stated below, we have assumed, with your consent, the accuracy of the factual representations contained in the Certificate of Representations provided to us by the Company, and that each such representation contained in such Certificate of Representations to the best of the Company’s knowledge or belief is accurate and complete without regard to such qualification as to the best of such entity’s knowledge or belief. These representations generally relate to the organization and proposed method of operation of the Company.

Based upon, subject to, and limited by the assumptions and qualifications set forth herein, including, without limitation, the discussion in the paragraphs below, we are of the opinion that:

1. Commencing with its taxable year ended December 31, 2013, the Company has been organized and operated in conformity with the requirements for qualification and taxation as a real estate investment trust (a “REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”), and its current and proposed method of operation as described in the Registration Statements and as set forth in the Certificate of Representations will enable the Company to continue to meet the requirements for qualification and taxation as a REIT under the Code; and

2. The statements in the Registration Statement under the caption “U.S. Federal Income Tax Considerations,” as modified and supplemented by the statements in the Prospectus Supplement under the caption “Additional U.S. Federal Income Tax Considerations,” to the extent they purport to summarize or describe matters of law and legal conclusions, are correct in all material respects.

The opinions set forth in this letter are based on relevant provisions of the Code, Treasury Regulations promulgated thereunder, interpretations of the foregoing as expressed in court decisions, legislative history, and existing administrative rulings and practices of the IRS (including its practices and policies in issuing private letter rulings, which are not binding on the IRS except with respect to a taxpayer that receives such a ruling), all as of the date hereof. These provisions and interpretations are subject to change, which may or may not be retroactive in effect, and which may result in modifications of our opinions. Our opinions do not foreclose the possibility of a contrary determination by the IRS or a court of competent jurisdiction, or of a contrary determination by the IRS or the Treasury Department in regulations or rulings issued in the future. In this regard, an opinion of counsel with respect to an issue represents counsel’s best professional judgment with respect to the outcome on the merits with respect to such issue, if such issue were to be litigated, but an opinion is not binding on the IRS or the courts and is not a guarantee that the IRS will not assert a contrary position with respect to such issue or that a court will not sustain such a position asserted by the IRS.

In connection with such opinions, we note that a significant portion of the Company’s assets consist of financing receivables that are secured by liens on structural improvements installed in buildings, and a significant portion of the Company’s taxable income is interest income earned with respect to such financing receivables. On August 30, 2016, the Treasury Department and the IRS issued final regulations defining “real property” for purposes of the REIT asset tests (the “Real Property Regulations”). The Real Property Regulations apply to the Company with respect to its taxable years beginning after December 31, 2016. Among other things, the Real Property Regulations provide that an obligation secured by a structural component of a building or other inherently permanent structure qualifies as a real estate asset for REIT qualification purposes only if such obligation is also secured by a real property interest in the inherently permanent structure served by the structural component. The structural improvements securing the Company’s financing receivables generally qualify as “fixtures” under local real property law, as well as under the Uniform Commercial Code (the “UCC”), which governs rights and obligations of parties in secured transactions. Although not controlling for REIT purposes, the general rule in the United States is that once improvements are permanently installed in real properties, such improvements become fixtures and thus take on the character of and are considered to be real property for certain state and local law purposes. In general, in the United States, laws governing fixtures, including the UCC and real property law, afford lenders who have secured their financings with security interests in fixtures with rights that extend not just to the fixtures that secure their financings, but also to the real properties in which such fixtures have been installed. By way of example only, Section 9-604(b) of the UCC, which has been adopted in all but two states in the United States, permits a lender secured by fixtures, upon a default, to enforce its rights under the UCC or under applicable real property laws. Although there is limited authority directly on point, given the nature of, and the extent to which the structural improvements securing the Company’s financing receivables are integrated into and serve the related buildings, our opinion is based on our conclusion that the better view is that the nature and scope of the Company’s rights in such buildings that inure to the Company as a result of the Company’s financing receivables are sufficient to satisfy the requirements of the Real Property Regulations described above. In this regard, it should be noted that the Real Property Regulations do not define what is required for an obligation secured by a lien on a structural component to also be secured by a real property interest in the building served by such structural component. However, the initial proposed version of the Real Property Regulations, which never became effective, included a requirement that the interest in the real property held by a REIT be “equivalent” to the interest in a structural component held by the REIT in order for the structural component to be treated as a real estate asset. This requirement was ultimately not included in the final Real Property Regulations, in part in response to comments that such requirement may negatively affect investment in energy efficient and renewable energy assets. We believe the deletion of this requirement implies that under the final Real Property Regulations, the Company’s rights in the building need not be equivalent to the Company’s rights in the structural components serving the building. Furthermore, real property law is typically relegated to the states and the specific rights available to any lien or mortgage holder, including the Company’s rights as a fixture lien holder described above, may vary between

jurisdictions as a result of a range of factors, including the specific local real property law requirements and judicial and regulatory interpretations of such laws, and the competing rights of mortgage and other lenders. While a number of cases have addressed the rights of fixture lien holders generally, there are limited judicial interpretations in only a few jurisdictions that directly address the rights and remedies available to a fixture lien holder in the real property in which the fixtures have been installed. Such rights have been addressed in some cases which support our conclusion and, in factual circumstances distinguishable from the Company’s own, in some cases where the courts have found these rights to be more limited. The resolution of these issues in many jurisdictions therefore remains uncertain. As a result of the foregoing, no assurance can be given that the IRS will not challenge our conclusion that the Company’s financing receivables meet the requirements of the Real Property Regulations or that, if challenged, such position would be sustained, in which case the Company would be required to pay a significant penalty tax or would fail to qualify as a REIT.

Prior to the issuance of the Real Property Regulations, the IRS issued to the Company the Ruling, which, based on the representations and assumptions contained therein, held that the Company’s financing receivables qualify as real estate assets and the income from such financing receivables qualify as income from mortgages on real property for purposes of the REIT requirements. The preamble to the Real Property Regulations provides that, to the extent a private letter ruling issued prior to the issuance of the Real Property Regulations is inconsistent with the Real Property Regulations, the private letter ruling is revoked prospectively from the applicability date of the Real Property Regulations. We do not believe that the Ruling is inconsistent with the Real Property Regulations because we believe the analysis in the Ruling was based on similar principles as the relevant portions of the Real Property Regulations, and accordingly we do not believe that the Real Property Regulations impact the Company’s ability to rely on the Ruling. However, no assurance can be given that the IRS could not successfully assert that the Company is not permitted to rely on the Ruling because the Ruling has been revoked by the Real Property Regulations.

The opinions set forth above represent our conclusions based upon the documents, facts, representations and assumptions referred to above. Any material amendments to such documents, changes in any significant facts or inaccuracy of such representations or assumptions could affect the opinions referred to herein. Moreover, the Company’s qualification as a REIT depends upon the ability of the Company to meet for each taxable year, through actual annual operating results, requirements under the Code regarding gross income, assets, distributions and diversity of stock ownership. We have not undertaken to review the Company’s compliance with these requirements on a continuing basis. Accordingly, no assurance can be given that the actual results of the Company’s operations for any single taxable year will satisfy the tests necessary to qualify as or be taxed as a REIT under the Code. In addition, the opinion set forth above does not foreclose the possibility that the Company may have to pay an excise or penalty tax, which could be significant in amount, in order to maintain its REIT qualification. Although we have made such inquiries and performed such investigations as we have deemed necessary to fulfill our professional responsibilities as counsel, we have not undertaken an independent investigation of all of the facts referred to in this letter or the Certificate of Representations.
