SECTION 6. Indemnification.

(a) Indemnification of Initial Purchasers. The Company and each of the Guarantors, jointly and severally, agree to indemnify and hold harmless each Initial Purchaser, its directors, its officers, its affiliates, as such term is defined in Rule 501(b) under the 1933 Act (each, an “Affiliate”) and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the General Disclosure Package, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto) or the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

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

(iii) against any and all fees and other expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the ▇.▇. ▇▇▇▇▇▇ Securities),

reasonably incurred in investigating, preparing or defending against any litigation, suit, action or proceeding or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information relating to any Initial Purchaser furnished to the Company by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, the General Disclosure Package, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto).

(b) Indemnification of the Company and the Guarantors. Each Initial Purchaser severally agrees to indemnify and hold harmless the Company, the Guarantors, each of their respective directors and officers and each person, if any, who controls the Company or any of the Guarantors 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)(i) of this Section 6, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Preliminary Offering Memorandum, the General Disclosure Package, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, the General Disclosure Package, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto), it being understood and agreed upon that the only such information furnished by any Initial Purchaser consists of the following information in the Preliminary Offering Memorandum and the Offering Memorandum furnished on behalf of each Initial Purchaser: under the caption “Plan of distribution,” the third paragraph, the fourth and fifth sentences of the seventh paragraph, and the ninth paragraph.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by ▇.▇. ▇▇▇▇▇▇ Securities, 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. In addition, the indemnifying party shall be entitled, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense of any claim or action brought against an indemnified party with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 6 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that ▇.▇. ▇▇▇▇▇▇ Securities shall

have the right to employ one counsel (in addition to local counsel) to represent them and those other Initial Purchasers and their respective officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Initial Purchasers against the indemnifying party under this Section 6 if, in the reasonable judgment of ▇.▇. ▇▇▇▇▇▇ Securities, either (i) there is an actual or potential conflict between the position of the indemnifying party on the one hand and the Initial Purchasers on the other hand or (ii) there may be defenses available to it or them that are different from or additional to those available to the indemnifying party (in any of which events the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified parties), in any of which events such reasonable fees and expenses shall be borne by the indemnifying party. 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, in form and substance reasonably satisfactory to such indemnified party, from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or any 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.

SECTION 7. Contribution.

(a) 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, in lieu of indemnifying such indemnified party thereunder, shall contribute to the aggregate amount paid or payable by such indemnified party as a result 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 and the Guarantors on the one hand and the Initial Purchasers on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors on the one hand and of the Initial Purchasers 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.

(b) The relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the Guarantors and the total discounts and commissions received by the Initial Purchasers in connection therewith as provided in this Agreement, bear to the aggregate offering price of the Securities as set forth on the cover of the Offering Memorandum.

(c) The relative fault of the Company and the Guarantors on the one hand and the Initial Purchasers 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 any such omission or alleged omission to state a material fact relates to information supplied by the Company or any Guarantor or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(d) The Company, the Guarantors and the Initial Purchasers 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 Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages and expenses incurred by such indemnified party and referred to above in this Section 7 shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, suit, action or proceeding 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.

(e) Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities purchased by it exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

(f) No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(g) For purposes of this Section 7, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Initial Purchaser’s officers, Affiliates and selling agents shall have the same rights to contribution as such Initial Purchaser, and each director and officer of the Company or a Guarantor and each person, if any, who controls the Company or a Guarantor 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 and the Guarantors. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the aggregate principal amount of Notes set forth opposite their respective names in Schedule A hereto and not joint.

(h) The remedies provided for in Section 6 and this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity.

SECTION 8. Representations, Warranties and Agreements of the Initial Purchasers.

(a) Each Initial Purchaser, severally and not jointly, represents, warrants and agrees that:

(i) it is a qualified institutional buyer within the meaning of Rule 144A under the 1933 Act (a “QIB”) and an accredited investor within the meaning of Rule 501(a) of Regulation D;

(ii) it has not solicited offers for, or offered or sold, and will not solicit offers for, or offer or sell, the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(a)(2) of the 1933 Act; and

(iii) it has not solicited offers for, or offered or sold, and will not solicit offers for, or offer or sell, the Securities as part of their initial offering except:

(b) Each Initial Purchaser acknowledges and agrees that the Company and, for purposes of the “no registration” opinions to be delivered to the Initial Purchasers pursuant to Sections 5(c) and 5(e), counsel for the Company and counsel for the Initial Purchasers, respectively, may rely upon the accuracy of the representations and warranties of the Initial Purchasers, and compliance by the Initial Purchasers with their agreements, contained in paragraph (a) above (including Annex A hereto), and each Initial Purchaser hereby consents to such reliance.

(c) Each Initial Purchaser hereby represents and agrees that it has not and will not use, authorize use of, refer to, or participate in the planning for use of, any written communication that constitutes an offer to sell or the solicitation of an offer to buy the Securities other than (i) the Preliminary Offering Memorandum and the Offering Memorandum, (ii) any written communication that contains either (a) no “issuer information” (as defined in Rule 433(h)(2) under the ▇▇▇▇ ▇▇▇) or (b) “issuer information” that was included (including through incorporation by reference) in the General Disclosure Package or the Offering Memorandum, (iii) any written communication listed on Schedule C or prepared pursuant to Section 3(a) (including any electronic road show) above, (iv) any written communication prepared by such Initial Purchaser and approved by the Company and the Representative in advance in writing or (v) any written communication relating to or that contains the preliminary or final terms of the Securities or their offering and/or other information that was included (including through incorporation by reference) in the General Disclosure Package or the Offering Memorandum.

(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 and 9 shall survive such termination and remain in full force and effect.

SECTION 11. Default by One or More of the Initial Purchasers.

(a) If any Initial Purchaser shall fail at the Closing Time to purchase the Securities which it has agreed to purchase under this Agreement (the “Defaulted Securities”), the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Defaulted Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Defaulted Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Defaulted Securities on such terms.

(b) If, after giving effect to any arrangements for the purchase of the Defaulted Securities by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of all the Securities to be purchased on such date, then the Company shall have the right to require each of the non-defaulting Initial Purchasers, severally and not jointly, to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder plus such Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the Defaulted Securities for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Defaulted Securities by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of all the Securities to be purchased on such date, or if the Company shall not exercise the right describe in paragraph (b) above, then this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser. Any termination of this Agreement pursuant to this Section 11 shall be without liability on the part of the Company or the Guarantors, except that the Company and each of the Guarantors will continue to be liable for the payment of expenses as set forth in Section 4 hereof and except that the provisions of Section 6 hereof shall not terminate and shall remain in effect.

As used herein, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule A hereto that was substituted for an Initial Purchaser pursuant to this Section 11.

This pricing term sheet is qualified in its entirety by reference to the Preliminary Offering Memorandum, dated December 12, 2017 (the “Preliminary Offering Memorandum”).

Accordingly, the Notes are being offered only to (1) persons reasonably believed to be “qualified institutional buyers” as defined in Rule 144A under the Securities Act and (2) outside the United States to non-U.S. persons in compliance with Regulation S under the Securities Act.
