7. Reimbursement of Purchasers’ Expenses.

8. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Purchaser, the directors, officers, employees, affiliates and agents of each Purchaser and each person, if any, who controls any Purchaser within the meaning of the Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Circular, the Final Offering Circular or any Issuer Free Writing Communication, or in all cases any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Purchaser through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have to any Purchaser or to any officer, employee or controlling person of that Purchaser;

(b) Each Purchaser severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, its officers, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Purchaser, but only with reference to written information relating to such Purchaser furnished to the Company by or on behalf of such Purchaser through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Purchaser may otherwise have. The Company acknowledges that the statements set forth in the twelfth paragraph under the heading “Plan of Distribution” constitute the only information furnished in writing by or on behalf of the several Purchasers for inclusion in the Disclosure Package or the Final Offering Circular;

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent the indemnifying party did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided

in paragraph (a) or (b) above. The indemnifying party shall be entitled to assume the defense thereof and to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel, and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel (including local counsel) if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (x) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of an indemnified party; and

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Purchasers severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company and one or more of the Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Purchasers on the other from the offering of the Offered Securities; provided, however, that in no case shall any Purchaser (except as may be provided in any agreement among purchasers relating to the offering of the Offered Securities) be responsible for any amount in excess of the total price at which the Offered Securities sold and distributed by such Purchaser was offered to the qualified institutional buyers. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Purchasers severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Purchasers on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Purchasers shall be deemed to be equal to the total initial purchasers’ discounts and commissions received by the Purchasers with respect to the Offered Securities purchased under this Agreement. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Purchaser within the meaning of the Act and each director, officer, employee, affiliate and agent of an Purchaser shall have the same rights to contribution as such Purchaser, and each person who controls the Company within the meaning of the Act, each officer of the Company and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by a Purchaser. If on the Closing Date any one or more Purchasers shall fail to purchase and pay for any of the Firm Securities agreed to be purchased by such Purchaser or Purchasers hereunder and the aggregate principal amount of Firm Securities that such defaulting Purchaser or Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of Firm Securities that the Purchasers are obligated to purchase and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, then the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Purchasers, or any other purchasers, to purchase all, but not less than all of the unsold Firm 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 the non-defaulting Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Firm Securities set forth opposite their names in Schedule II hereto bears to the aggregate principal amount of Firm Securities set forth opposite the names of all the non-defaulting Purchasers) the Firm Securities which the defaulting Purchaser or Purchasers agreed but failed to purchase. If any Purchaser or Purchasers so default and the aggregate principal amount of Firm Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Firm Securities that the defaulting Purchaser is obligated to purchase on the Closing Date and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Purchaser or the Company, except as provided in Section 11. If, on the Additional Closing Date, any one or more Purchasers shall fail to purchase and pay for any of the Option Securities agreed to be purchased by such Purchaser or Purchasers hereunder and the aggregate principal amount of Option Securities that such defaulting Purchaser or Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of Option Securities that the Purchasers to be purchased on the Additional Closing Date, the non-defaulting Purchasers shall have the option to (a) terminate their obligation hereunder to purchase the Option Securities to be sold on the Additional Closing Date or (b) purchase not less than the principal amount of Option Securities that such non-defaulting Purchasers would have been obligated to purchase in the absence of such default. As used in this Agreement, the term “Purchaser” includes any person substituted for a Purchaser under this Section. Nothing contained in this Agreement shall relieve any defaulting Purchaser of its liability, if any, to the Company and any non-defaulting Purchaser for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Firm Securities, if at any time prior to such time, (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the NYSE, (ii) trading in securities generally on the NYSE or the Nasdaq Stock Market shall have been suspended or limited or minimum prices shall have been established on any of such exchanges, (iii) a banking moratorium shall have been declared either by authorities in the United States or New York state or there shall have occurred a material disruption in commercial banking or securities settlement or clearance services, (iv) there shall have occurred a change or development involving a prospective change in United States taxation affecting the Offered Securities or the transfer thereof or the imposition of exchange controls by the United States or (v) there shall have occurred any outbreak or escalation of hostilities, except as existing with similar severity on the date hereof involving the United States, declaration by the United States of a national emergency or war, or other calamity or crisis, except as existing with similar severity on the date hereof, the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Firm Securities as contemplated by the Disclosure Package and the Final Offering Circular.

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Purchaser or the Company or any of the officers, directors, employees, affiliates, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Offered Securities. The provisions of Sections 7, 8 and 16 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to Credit Suisse Securities (USA) LLC (fax no.:), Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: and Xxxxxxx Xxxxx & Co.

14. Representation of Purchasers. The Representatives will act for the several Purchasers in connection with this Agreement, and any action under this Agreement taken by the Representatives will be binding upon all the Purchasers.

15. No Advisory or Fiduciary Responsibility. The Company acknowledges and agrees that (i) the purchase and sale of the Offered Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Purchasers, on the other, (ii) in connection therewith and with the process leading to such transaction each Purchaser is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Purchaser has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Purchaser has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company has been advised that the Representatives and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Representatives have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship. The Company agrees that it will not claim that any Purchaser has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto. The Company waives, to the fullest extent permitted by law, any claims it may have against the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Representatives shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

Use of Proceeds:		The Issuer estimates that the net proceeds from the offering will be approximately $1.1 billion (or approximately $1.3 billion if the initial purchasers exercise their option to purchase additional Notes in full), after deducting fees and estimated expenses. The Issuer entered into capped call transactions with certain of the initial purchasers or affiliates thereof (the “option counterparties”). The Issuer intends to use approximately $98.3 million (or $113.1 million if the initial purchasers exercise their option to purchase additional notes in full) of the net proceeds from the offering to pay the cost of the capped call transactions. The cap price of the capped call transactions will initially be $156.2140 per share of common stock, which represents a premium of 85% over the last reported sale price per share of our common stock on the New York Stock Exchange of $84.44 per share on May 11, 2020.

		The Issuer expects to use approximately $50.0 million of the net proceeds from the offering to repurchase shares of the Issuer’s common stock from purchasers of Notes in the offering in privately negotiated transactions effected with or through one or more of the initial purchasers or their affiliates. The purchase price per share of the common stock repurchased in such transactions is equal to the closing sale price per share of the Issuer’s common stock on the date of the Preliminary Offering Circular, which was $84.44 per share. These repurchases could increase, or prevent a decrease in, the market price of our common stock or the notes concurrently with the pricing of the notes, and could result in a higher effective conversion price for the notes.

		The Issuer expects to use a portion of the net proceeds from the offering to fund all of the Issuer’s obligations under the Tender Offers, including fees and expenses incurred in connection therewith. The remaining proceeds will be used for general corporate purposes, which may include the repayment of outstanding borrowings under the Issuer’s credit facility and other outstanding indebtedness. See “Use of Proceeds” in the Preliminary Offering Circular.



		If the initial purchasers exercise their option to purchase additional Notes, the Issuer expects to use the net proceeds from the sale of the additional Notes to enter into additional capped call transactions with the option counterparties and any remaining proceeds will be used for general corporate purposes.

Increase in Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change or a Notice of Redemption:		If the effective date of a “make-whole fundamental change” (as defined in the Preliminary Offering Circular) occurs prior to the maturity date of the Notes or if the Issuer gives a notice of redemption with respect to any or all of the Notes, the Issuer will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Notes in connection with such a make-whole fundamental change or notice of redemption, as the case may be, as described under “Description of Notes—Conversion Rights—Increase in Conversion Rate upon Conversion upon a Make- Whole Fundamental Change or Notice of Redemption” in the Preliminary Offering Circular.

		The following table sets forth the number of additional shares by which the conversion rate will be increased per $1,000 principal amount of Notes for conversions in connection with a make-whole fundamental change or notice of redemption, as the case may be, for each “stock price” and “effective date” set forth below:

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

•

If the stock price is between two stock prices in the table above or the effective date is between two effective dates in the table above, the number of additional shares by which the conversion rate will be increased 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 $200.00 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above as described in the Preliminary Offering Circular), no additional shares will be added to the conversion rate.

•

If the stock price is less than $84.44 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above as described in the Preliminary Offering Circular), no additional shares will be added to the conversion rate.

Notwithstanding the foregoing, in no event will the conversion rate per $1,000 principal amount of Notes exceed 11.8427 shares of the Issuer’s common stock, subject to adjustment in the same manner as the conversion rate as set forth under “Description of Notes—Conversion Rights—Conversion Rate Adjustments” in the Preliminary Offering Circular.

The Preliminary Offering Circular is modified as follows:

The second paragraph under “Ranking” on page 4 and on page 23 is replaced with the following:

At March 31, 2020, we had $2.6 billion of indebtedness for borrowed money ranking equally in right of payment with the notes, and our subsidiaries had aggregate balance sheet liabilities of $2.6 billion, excluding intercompany liabilities, to which the notes would have been structurally subordinated.

The third sentence in the first paragraph under “The notes are effectively subordinated to any liabilities of our subsidiaries and to any secured debt we may incur in the future” on page 8 is replaced with the following:

At March 31, 2020, we had $2.6 billion of indebtedness for borrowed money ranking equally in right of payment with the notes, none of which was secured, and our subsidiaries had aggregate balance sheet liabilities of $2.6 billion, excluding intercompany liabilities.
