affecting the Issuer or any Subsidiary which involves the possibility of any judgment or liability against the Issuer or any Subsidiary not fully covered by insurance (except for normal deductibles), and which would have a Material Adverse Effect.

 Section 3.4. No Breach. Neither the execution and delivery of this Note, nor compliance with the terms and provisions hereof, will
conflict with or result in a breach of, or require any consent which has not been obtained as of the Closing Date under, the respective charter, limited partnership agreement, articles of organization or by-laws of the Issuer or any Subsidiary, or
any Governmental Requirement, or any agreement or instrument to which the Issuer or any Subsidiary is a party or by which it is bound or to which it or its Properties are subject, or constitute a default under any such agreement or instrument, or

regarding each Plan. 
 (b) Each Plan is, and has been, maintained in substantial compliance with ERISA and, where applicable,
the Code.

fiduciary duty liability damages under section 409 of ERISA. 
 (d) No contingent obligations remain due to the termination of

 (b) Any legal action

hereby accepts for itself and (to the extent permitted by Law) in respect of its Property, generally and unconditionally, the jurisdiction of the
aforesaid courts. The Issuer hereby irrevocably waives any objection, including, without limitation, any objection to the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter have to the
bringing of any such action or proceeding in such respective jurisdictions. This submission to jurisdiction is non-exclusive and does not preclude the Holder from obtaining jurisdiction over the Issuer in any court otherwise having jurisdiction.

 (c) The Issuer hereby designates CT Corporation System located at
111 Eighth Avenue, 13th Floor, New York, New York, 10011, or other agent acceptable to the Holder, as the designee, appointee and agent of the Issuer to
receive, for and on behalf of the Issuer, service of process in such respective jurisdictions in any legal action or proceeding with respect to this Note. It is understood that a copy of such process served on such agent will be promptly forwarded
by overnight courier to the Issuer at its address set forth under its signature below, but the failure of the Issuer to receive such copy shall not affect in any way the service of such process. The Issuer further irrevocably consents to the service
of process of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to the Issuer at its said address, such service to become effective thirty
(30) days after such mailing. 
 (d) Nothing herein shall
affect the right of the Holder to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against the Issuer in any other jurisdiction. 
 (e) The Issuer and the Holder hereby (i) irrevocably and unconditionally waive, to the fullest extent permitted by law, trial by
jury in any legal action or proceeding relating to this Note and for any counterclaim therein; (ii) irrevocably waive, to the maximum extent not prohibited by law, any right it may have to claim or recover in any such litigation any special,
exemplary, punitive or consequential damages, or damages other than, or in addition to, actual damages; (iii) certify that no party hereto or counsel for any party hereto has represented, expressly or otherwise, or implied that such party would
not, in the event of litigation, seek to enforce the foregoing waivers, and (iv) acknowledge that it has been induced to enter into this Note and the transactions contemplated hereby and thereby by, among other things, the mutual waivers and
certifications contained in this Section 8.13. 
 Section 8.15. Interest. It is the intention of the
parties hereto to conform strictly to applicable usury laws regarding the use, forbearance or detention of the indebtedness evidenced by this Note, whether such laws are now or hereafter in effect, including the laws of the United States of America
or any other jurisdiction whose laws are applicable, and including any subsequent revisions to or judicial interpretations of those laws, in each case to the extent they are applicable to this Note (the “Applicable Usury
Laws”). Accordingly, if any acceleration of the maturity of the Note or any payment by the Issuer or any other Person produces a rate in excess of the Highest Lawful Rate or otherwise results in the Issuer or such other Person being
deemed to have paid any interest in excess of the Maximum Amount, as hereinafter defined, or if the Holder shall for any reason receive any unearned interest in violation of any Applicable 








 
Usury Laws, or if any transaction contemplated hereby would otherwise be usurious under any Applicable Usury Laws, then, in that event, regardless of any
provision contained in this Note or other agreement or instrument executed or delivered in connection herewith, the provisions of this Section 8.15 shall govern and control, and neither the Issuer nor any other Person shall be
obligated to pay, or apply in any manner to, any amount that would be excessive interest. The Holder shall not ever be deemed to have contracted for or be entitled to receive, collect, charge, reserve or apply as interest on this Note (whether
termed interest therein or deemed to be interest by judicial determination or operation of law), any amount in excess of the Highest Lawful Rate, and, in the event that the Holder ever receives, collects, or applies as interest any such excess, such
amount which would be excessive interest shall be applied as a partial prepayment of principal and treated hereunder as such, and, if the principal amount of this Note is paid in full, any remaining excess shall forthwith be paid to the Issuer. In
determining whether or not the interest contracted for, received, collected, charged reserved, paid or payable, including under any specific contingency, exceeds the Highest Lawful Rate, the Issuer and the Holder shall, to the maximum extent
permitted under applicable law, (i) characterize any non-principal payment (other than payments which are expressly designated as interest payments hereunder) as an expense or fee rather than as interest, (ii) exclude voluntary
pre-payments and the effect thereof, and (iii) amortize and spread the total amount of interest throughout the entire stated term of the Note so that the interest rate is uniform throughout such term; provided that if the Note is paid in
full prior to the end of the full contemplated term hereof, and if the interest received for the actual period of existence thereof exceeds the Highest Lawful Rate, if any, then the Holder shall refund to the Issuer the amount of such excess, or
credit the amount of such excess against the aggregate unpaid principal balance of this Note. As used herein, the term “Maximum Amount” means the maximum nonusurious amount of interest which may be lawfully contracted for,
reserved, charged, collected or received by the Holder in connection with the indebtedness evidenced by this Agreement under all Applicable Usury Laws.
