(2)           The Company has delivered to each Underwriter, without charge, as many copies of each Pricing Prospectus, Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as such Underwriter has reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act.  The Company will furnish to each Underwriter, without charge, for so long as the delivery of a Final Prospectus is required under the 1933 Act or 1934 Act, such number of copies of the Final Prospectus as such Underwriters may reasonably request.  The Final Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical, save for minor formatting differences, to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T of the Commission.

(d)           Modification of Disclosure Package.  If there occurs an event or development as a result of which the Disclosure Package would include an untrue statement of a material fact or would 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 Company will notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented.

(e)           Continued Compliance with Securities Laws.  The Company will comply

12

with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the rules and regulations of the Commission thereunder (the “1934 Act Regulations”), so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Disclosure Package and the Final Prospectus, except where the failure to comply will not adversely affect the distribution of the Securities.  If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary for the Company to amend the Registration Statement or amend or supplement the Final Prospectus in order that the Final Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time such Final Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the 1933 Act) is delivered to a purchaser, or if it shall be necessary at any such time to amend the Registration Statement or amend or supplement the Final Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Final Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f)            Rule 158.  The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its security holders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act and the 1933 Act Regulations relating thereto.

(g)           Use of Proceeds.  The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Pricing Prospectus and Final Prospectus under “Use of Proceeds.”

(h)           Limitation on Free Writing Prospectuses.  The Company agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the 1933 Act Regulations) required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the 1933 Act Regulations, other than the final term sheet prepared and filed pursuant to Section 3(b) hereof; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectus included in Schedule C hereto. Any such free writing prospectus consented to by the Representatives or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.”  The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the 1933 Act Regulations applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

13

(i)            Sale or Disposition of Debt Securities.  For the period beginning the date of this Agreement through and including the business day following the Closing Time, the Company will not, without the prior written consent of the Representatives, directly or indirectly, issue, sell, offer to sell, grant any option for the sale of or otherwise dispose of, any debt securities substantially similar to the Securities.

SECTION 4.         Payment of Expenses.

(b)           Termination of Agreement.  If this Agreement is terminated by the Representatives in accordance with the provisions of Section 5 or subsections (a)(i) and (a)(v) of Section 9 hereof, the Company shall reimburse the Underwriters for all reasonable out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Underwriters.

SECTION 6.         Indemnification.

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

(i)            against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in the Basic Prospectus, the Pricing Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus, the investor presentation dated December 8, 2017, or the information contained in the final term sheet required to be prepared and filed pursuant to Section 3(b) hereof, or in any amendment or supplement thereto, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the

16

circumstances under which they were made, not misleading;

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

(iii)          against any and all expense whatsoever, as incurred (including, subject to Section 6(c) hereof, the reasonable fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), or the Basic Prospectus, the Pricing Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus, the investor presentation dated December 8, 2017, or the information contained in the final term sheet required to be prepared and filed pursuant to Section 3(b) hereof, or in any amendment or supplement thereto; and provided, further, that the foregoing indemnity agreement by the Company shall not inure to the benefit of any Underwriter from whom the person asserting any losses, claims, damages or liabilities otherwise covered by this paragraph purchased Securities if the Company shall have furnished to the Underwriters prior to the Applicable Time a copy of a Free Writing Prospectus, if any, or Pricing Prospectus (as then amended and supplemented), and such document was not sent or given by or on behalf of such Underwriter to such person if required so to have been delivered, and if such Free Writing Prospectus, if any, or Pricing Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, expense, claim, damage or liability or such loss, expense, claim, damage or liability arises from the continued use by such Underwriter of the Disclosure Package following its receipt of notice of an event or occurrence pursuant to Section 3(d).

(b)           Indemnification of Company, Trustees, Partners and Officers.  Each Underwriter severally agrees to indemnify and hold harmless the Company, its partners, each of the officers of the Trust 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), the Pricing Prospectus or the Final Prospectus, the investor presentation dated December 8, 2017, or in any amendment or supplement thereto, in

17

reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), the Basic Prospectus, the Pricing Prospectus or the Final Prospectus, or in any amendment or supplement thereto.

(c)           Actions against Parties; Notification.  Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement.  In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company.  An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party.  In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.  Subject to Section 6(d), 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 in accordance with Section 6(a)(iii) hereof, 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, (iii) such indemnifying party, if it has not theretofore paid such reimbursement, is requested again to pay reimbursement at least five, but not more than ten, days prior to such settlement being entered into, and (iv) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

18

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 Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the 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 total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Final Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7.  The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

19

For purposes of this Section 7, each officer or director of each Underwriter and person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each partner and officer of the Company who signed the Registration Statement, each trustee of the Trust, each officer of the Trust 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.

SECTION 8.         Representations, Warranties and Agreements to Survive Delivery.  All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Trust or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Underwriters or any controlling person of an Underwriter, or by or on behalf of the Company or any officer or trustee of the Trust or partner or controlling person of the Company, and shall survive delivery of the Securities to the Underwriters.

SECTION 9.         Termination of Agreement.

(a)           Termination; General.  The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Disclosure Package and the Final Prospectus, any material adverse change in or affecting the condition, financial or otherwise, or the earnings or business affairs of the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States, or any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to commence or continue the offering of the Securities to the public or to enforce contracts for the sale of the Securities, 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 if trading generally on the New York Stock Exchange 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 such exchanges or by order of the Commission or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal or New York authorities, or (v) if, since the time of execution of this Agreement, there shall have been any downgrading in the rating of any of the Company’s debt securities by any “nationally recognized statistical rating organization” (as such term is defined in Section 3(a)(62) of the 1934 Act) or any notice given of any intended or potential downgrading in any such rating.

(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, 15 and 16 shall survive such termination and remain in full force and effect.

20

SECTION 10.       Default by One or More of the Underwriters.

(a)           Substitution of Defaulting Underwriters.  If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase under this Agreement, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Securities on such terms. In the event that, within the respective prescribed periods, the Representatives notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone the Closing Time for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement, the Disclosure Package or the Final Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement, the Disclosure Package or the Final Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in the Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement.

(b)           Purchase by Non-Defaulting Underwriters.  If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives or the Company, or both, as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-tenth of the aggregate principal amount of the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities which such Underwriter agreed to purchase under this Agreement and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase under this Agreement) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c)           Termination.  If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives or the Company, or both, as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-tenth of the aggregate principal amount of the Securities, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the party of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters provided in Section 4 hereof and the indemnity and contribution agreements in Sections 6 and 7 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

SECTION 11.       Notices.  All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard

21

form of telecommunication.  Notices to the Underwriters shall be directed to the Representatives as set forth in Schedule B; and notices to the Company shall be directed to it at 888 Seventh Avenue, New York, New York 10019, attention of the Chief Financial Officer.

SECTION 12.       No Fiduciary Duty.  The Company hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Company and (c) the Company’s engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company on related or other matters).  The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

SECTION 13.       Parties.  This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company and their respective successors.  Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company, and their respective successors and the controlling persons and officers, trustees and partners referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.  This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company and their respective successors, and said controlling persons and officers, trustees and partners and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.  No purchaser of the Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

22

SECTION 14.       Miscellaneous.  In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the underwriters to properly identify their respective clients.

SECTION 15.       Governing Law and Time.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 16.       Trial by Jury.  Each of the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its partners and affiliates) and the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby..

SECTION 17.       Effect of Headings.  The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

23

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement between the Underwriters and the Company in accordance with its terms.
