**Item 1.01. Entry Into a Material Definitive Agreement**

**Issuance of METC Senior Secured Notes**

On January 14, 2026, Michigan Electric Transmission Company, LLC ("METC"), an indirect wholly-owned subsidiary of ITC Holdings Corp. (the "Company"), issued $125,000,000 aggregate principal amount of its 5.08% Series A Senior Secured Notes due 2036 (the "Series A METC Notes") and $125,000,000 aggregate principal amount of its 5.71% Series B Senior Secured Notes due 2046 (the "Series B METC Notes" and together with the Series A METC Notes, the "METC Notes") in a private placement in reliance on an exemption from registration under the Securities Act of 1933, as amended (the "Securities Act"). The METC Notes were sold by METC to institutional accredited investors (as defined by Rule 501(a) of the Securities Act) pursuant to a Purchase Agreement dated January 14, 2026 (the "Purchase Agreement"). METC agreed to sell the METC Notes subject to the satisfaction of certain terms and conditions provided in the Purchase Agreement. METC will apply the net proceeds of the sale of the METC Notes to repay existing indebtedness under its Revolving Credit Agreement, dated as of April 14, 2023 (as amended by that Amendment No. 1 to Revolving Credit Agreement, dated as of December 16, 2024 and as further amended, modified, supplemented, restated and replaced from time to time), repay indebtedness under its intercompany loan agreement with ITC Holdings Corp., to partially fund capital expenditures, and for general corporate purposes.

The METC Notes were issued under METC's first mortgage indenture (the "Mortgage Indenture"), dated as of December 10, 2003, between The Bank of New York Mellon Trust Company, N.A., as successor to JPMorgan Chase Bank, as trustee (the "Trustee"), as supplemented by the thirteenth supplemental indenture thereto, dated as of December 16, 2025, between METC and the Trustee (the "Thirteenth Supplemental Indenture" and, together with the Mortgage Indenture, the "METC Indenture"). The METC Notes are secured by a first mortgage lien on substantially all of METC's real and tangible personal property equally with all other securities theretofore or thereafter issued under the Mortgage Indenture, with such exceptions as described in, and such releases as permitted by, the METC Indenture.

Interest on the Series A METC Notes is payable semi-annually on January 14 and July 14 of each year, commencing on July 14, 2026, at a fixed rate of 5.08% per annum. Interest on the Series B METC Notes is payable semi-annually on January 14 and July 14 of each year, commencing on July 14, 2026, at a fixed rate of 5.71% per annum. METC may redeem the METC Notes, in whole or in part, in an amount not less than $5,000,000 in aggregate principal amount in the case of a partial redemption, at any time or from time to time with not less than 10 days and not more than 60 days' prior notice at a redemption price equal to the sum of (a) 100% of the principal amount of such METC Notes, (b) accrued and unpaid interest thereon to the redemption date and (c) a make-whole amount, if any, determined using a discount rate of treasuries plus 90 basis points. METC may also redeem the Series A METC Notes in whole on or after October 14, 2035 at a redemption price equal to the principal amount of the Series A METC Notes plus accrued and unpaid interest thereon to the redemption date. METC may also redeem the Series B METC Notes in whole on or after July 14, 2045 at a redemption price equal to the principal amount of the Series B METC Notes plus accrued and unpaid interest thereon to the redemption date. The principal amount of the Series A METC Notes is payable on January 14, 2036 and the principal amount of the Series B METC Notes is payable on January 14, 2046.

The METC Notes and the METC Indenture contain events of default customary for such a transaction, including, without limitation, failure to pay interest on any Security (as defined in the METC Indenture) for five days after becoming due; failure to pay principal on any Security when due; failure to comply with material covenants contained in the METC Indenture, subject to a 30-day cure period; failure to comply with other covenants contained in the METC Indenture and the other financing agreements relating to the offering of the METC Notes, subject to a 60-day cure period; material breaches of representations and warranties; defaults in respect of obligations relating to certain debt; certain unsatisfied judgments; and certain events relating to reorganization, bankruptcy and insolvency of METC. If an "Event of Default" (as defined in the METC Indenture) occurs, any holder of the Securities may accelerate its Securities (rather than all the Securities) pursuant to any payment Event of Default; the trustee or holders of 25% (in the case of a payment default) or a majority (in the case of any other default) of the outstanding principal amount of the Securities may accelerate all the Securities pursuant to any Event of Default; and all amounts are automatically accelerated pursuant to any reorganization, bankruptcy or insolvency Event of Default.

The above description of the METC Indenture does not purport to be a complete statement of the parties' rights and obligations thereunder. Such description is qualified in its entirety by reference to the Thirteenth Supplemental Indenture, a copy of which is attached to this Current Report on Form 8-K as Exhibit 4.2, and the Mortgage Indenture, a copy of which was attached to the Company's [Quarterly Report on Form 10-Q for the quarter ended September 30, 2006](https://www.sec.gov/Archives/edgar/data/1317630/000095012406006388/k09554e10vq.htm) as Exhibit 4.1, each of which is incorporated herein by reference.

The Company shall be responsible for ensuring that only authorized officers transmit such Instructions to the Trustee and that the Company and all authorized officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee's reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

"Electronic Means" shall mean the following communications methods: e-mail, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the Trustee as available for use in connection with its services hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) For the purposes of the Notes, Section 907 is hereby supplemented by the addition of the following paragraph immediately following the last paragraph of Section 907:

The Trustee shall have a lien prior to the Securities as to all property and funds held by it hereunder for any amount owing it or any predecessor Trustee pursuant to this Section 907, except with respect to funds held in trust for the benefit of the Holders of particular Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) The following sentence shall be added immediately following the last sentence of Section 1004:

Delivery of such information, documents and other reports to the Trustee is for informational purposes only and the Trustee's receipt of such shall not constitute actual or constructive knowledge or 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 Officer's Certificates).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) For all purposes under this Agreement in connection with any division or plan of division under Delaware law (or any comparable event under a different jurisdiction's laws), (a) if any obligation or liability of any Person becomes the asset, right, obligation or liability of a different Person, then it shall be deemed to have been transferred from the original Person to the subsequent Person, and (b) if any new Person comes into existence, such new Person shall be deemed to have been organized on the first date of its existence by the holders of its Capital Stock at such time.

Section 2.02. <u>Payment on the Notes</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Subject to Section 2.02(b) hereof, payments of principal, Make-Whole Amount, if any, and interest becoming due and payable on the Notes shall be made at the Place of Payment designated in Section 2.01(f) hereof or such place as the Company may at any time, by notice, specify to each Noteholder, so long as such Place of Payment shall be either the principal office of the Company or the principal office of a bank or trust company in New York, New York.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) So long as any Initial Noteholder or its nominee shall be a Noteholder, and notwithstanding anything contained in the Mortgage Indenture, Section 2.02(a) hereof or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, and interest by the method and at the address specified for such purpose below such Initial Noteholder's name in Schedule A to the Note Agreement, or by such other method or at such other address as such Initial Noteholder shall have from time to time specified to the Company and the Trustee in writing for such purpose in accordance with the Note Agreement, without the presentation or surrender of such Note or the making of any notation thereon, except that concurrently with or reasonably promptly after payment or redemption in full of any Note, such Initial Noteholder shall surrender such Note for cancellation to the Company at its principal office or at the Place of Payment most recently designated by the Company pursuant to Section 2.02(a) hereof. Prior to any sale or other disposition of any Note held by such Initial Noteholder or its nominee such Initial Noteholder will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 305 of the Indenture; provided, that a transfer by endorsement shall not constitute a registration of transfer for purposes of the Indenture and the Trustee and any agent of the Trustee shall be entitled to the protections of Section 308 of the Indenture with respect to any Note, the transfer of which has not been so registered. The Company will afford the benefits of this Section 2.02(b) to any Institutional Investor that is the direct or indirect transferee of any Note purchased by such Initial Noteholder under the Indenture. The Company agrees and acknowledges that the Trustee shall not be liable for any Noteholder's failure to perform its obligations under this Section 2.02(b).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Notwithstanding anything to the contrary in Section 113 of the Mortgage Indenture, if the Stated Maturity or any Redemption Date of the Notes shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of the Mortgage Indenture or this Thirteenth Supplemental Indenture) payment of interest on or principal (and premium, if any) of the Notes due at the Stated Maturity or on any Redemption Date thereof need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Stated Maturity or on any Redemption Date thereof, provided that interest shall accrue on the outstanding principal amount of the Notes due at the Stated Maturity or on any Redemption Date thereof at the rate set forth in the Notes until the date of actual payment.

Section 2.03. <u>Mandatory Redemption of the Notes</u>.

In addition to the mandatory redemption required by Section 501(a) of the Mortgage Indenture, which Section 501(a) shall apply to the Notes, in the event that any one or more Dispositions during any consecutive 12-month period (except, subject to compliance with Section 610 of the Mortgage Indenture, Dispositions in the ordinary course of business of obsolete or worn out Property and real estate interests not needed by the Company for its Transmission System or for the conduct of its business and Dispositions of assets that would be permitted under Article Eleven of the Mortgage Indenture) yield Net Proceeds in excess of $10,000,000, in the aggregate, the Net Proceeds of such Disposition or Dispositions shall be used for the mandatory redemption of the Notes, and/or the redemption or prepayment of other Senior Secured Debt in accordance with its terms, on a date which is no more than nine months following a Disposition that, when aggregated with any other Dispositions, requires compliance with this Section 2.03 unless (x) during the nine-month period immediately preceding the date of such Disposition, the Company Invested in any Rate Base Assets in which case an amount of such Net Proceeds equal to the excess, if any, of (A) the total aggregate amount of all such Investments made during such preceding nine-month period (excluding, however, the amount of any Investments made pursuant to clause (b) of the definition of "Investment" that were not expended for Rate Base Assets during such nine-month period) over (B) the aggregate amount of Debt incurred by the Company (which, with respect to any Debt incurred under any permitted credit facility of a revolving nature, shall be calculated on a net basis after taking into account any borrowings, prepayments, repayments, reborrowings or other extensions of credit made by or in favor of the Company thereunder), in each case, during such preceding nine-month period, need not be applied to such redemption or prepayment, as the case may be, or (y) during the nine-month period following the date of such Disposition, the Company shall Invest in Rate Base Assets, in which case an amount of such Net Proceeds so Invested during such following nine-month period need not be applied to such redemption or prepayment, as the case may be; *provided, however*, that in the event that any such amounts referred to in this clause (y) Invested pursuant to clause (b) of the definition of "Investment" are not expended for Rate Base Assets within a period of six months from the end of such following nine-month period, any such amounts not so expended shall be used for the mandatory redemption of the Notes, and/or the redemption or prepayment of other Senior Secured Debt in accordance with its terms, on a date not later than the last day of such six month period. Any redemption of the Notes pursuant to this Section 2.03 shall be made (i) at a redemption price equal to the principal amount of the Notes being redeemed and shall be accompanied by payment of accrued and unpaid interest on the principal amount of the Notes so redeemed to the redemption date and a Make-Whole Amount and (ii) in accordance with the procedures for optional redemption set forth in Section 2.04(c) hereof. Notwithstanding anything to the contrary in this Section 2.03, any amounts utilized pursuant to clauses (x) or (y) above to reduce the amount of Net Proceeds required to be applied to redemption of the Notes and/or redemption or prepayment of other Senior Secured Debt in accordance with its terms may be utilized no more than once with respect to the Net Proceeds of any one or more Dispositions occurring in any consecutive twelve month period.

Section 2.04. <u>Optional Redemption</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Pursuant to Section 501(b) of the Mortgage Indenture, (i) the Series A Notes may be redeemed at the option of the Company, in whole, on or after October 14, 2035 and (ii) the Series B Notes may be redeemed at the option of the Company, in whole, on or after July 14, 2045, each at a redemption price equal to the principal amount of such Notes plus accrued and unpaid interest thereon to the redemption date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Notwithstanding anything to the contrary in Article Five of the Mortgage Indenture, the redemption of the Notes shall take place in accordance with the procedures and requirements set forth in this Section 2.04(c), without prejudice to the requirements of Section 502 of the Mortgage Indenture (which shall for purposes of this Thirteenth Supplemental Indenture also be applicable to a redemption under Section 2.03 hereof) and Sections 505 through 507 of the Mortgage Indenture. The Company (or the Trustee, if so requested pursuant to Section 504 of the Mortgage Indenture) shall give each Noteholder written notice of each optional redemption under this Section 2.04, or a mandatory redemption under Section 2.03 hereof, as the case may be, not less than ten (10) days and not more than sixty (60) days prior to the date fixed for such redemption. Each such notice shall specify such date, the aggregate principal amount of the Notes to be redeemed on such date, the principal amount of each Note held by such Noteholder to be redeemed (determined in accordance with Section 2.04(d) hereof) and the interest to be paid on the redemption date with respect to such principal amount being redeemed, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount, if applicable, due in connection with such redemption (calculated as if the date of such notice were the date of the redemption), setting forth the details of such computation. Two (2) Business Days prior to such redemption, the Company shall deliver to each Noteholder and the Trustee a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount, if applicable, as of the specified redemption date. The Trustee shall have no responsibility for such calculation. From and after the date of such redemption, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Notwithstanding anything to the contrary in Article Five of the Mortgage Indenture, in the case of each partial redemption of the Notes pursuant to Section 2.04(c) hereof, the Company shall redeem the same percentage of the unpaid principal amount of each of the Notes of each series, and the principal amount of each of the Notes of each series to be so redeemed shall be allocated by the Trustee among all of the Notes of such series at the time Outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts of each of the Notes not theretofor called for redemption.

Section 2.05. <u>Purchase of Notes</u>.

Except as may be agreed to by a Noteholder or Noteholders in connection with an offer made to all Noteholders on the same terms and conditions, the Company shall not and shall not permit any Affiliate to purchase, redeem or otherwise acquire, directly or indirectly, any of the Outstanding Notes, except upon the payment or redemption of the Notes in accordance with the terms of the Indenture. The Company will promptly cause the Trustee to cancel all Notes acquired by it or any Affiliate pursuant to any payment, redemption or purchase of Notes pursuant to any provision of the Indenture and no Notes may be issued in substitution or exchange for any such Notes.

Section 2.06. <u>Payment upon Event of Default</u>.

Upon any Notes becoming due and payable under Section 802 of the Indenture, whether automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including, without limitation, interest accrued thereon at the applicable rate for overdue payments) and (y) the Make-Whole Amount determined in respect of such principal amount, shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes have become due and payable under Section 802 of the Indenture, whether automatically or by declaration, as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

Section 2.07. <u>Transfers</u>.

In registering the transfer of any Note in accordance with Section 305 of the Mortgage Indenture, the Security Registrar and the Trustee shall have no responsibility to monitor securities law compliance in connection with any such transfer.

The parties agree to electronic contracting and signatures with respect to this Thirteenth Supplemental Indenture and the documents related hereto (other than the Notes). Delivery of an electronic signature to, or a signed copy of, this Thirteenth Supplemental Indenture and such other documents (other than the Notes) by email or other electronic transmission shall be fully binding on the parties to the same extent as the delivery of the signed originals and shall be admissible into evidence for all purposes.

All terms of an accounting or financial nature used herein or in the Mortgage Indenture shall be construed, and all computations of amounts and ratios referred to herein shall be made without giving effect to Accounting Standards Codification 842 (or any other Accounting Standards Codification or Financial Accounting Standard having a similar effect or result) (and related interpretations) (collectively, "<u>ASC 842</u>") to the extent the effect of which would be to cause leases which would be treated as operating leases under GAAP immediately prior to the effectiveness of ASC 842 to be recorded as a liability/debt on the Company's statement of financial position under GAAP.

Section 5.11. <u>Sanctions Representations</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Company covenants and represents that neither it nor any of its affiliates, subsidiaries, directors or officers are the target or subject of any sanctions enforced by the US Government, (including, without limitation, the Office of Foreign Assets Control of the US Department of the Treasury ("<u>OFAC</u>") or the US Department of State), the United Nations Security Council, the European Union, HM Treasury, or other relevant sanctions authority (collectively "<u>Sanctions</u>");

Section 5.12. <u>FATCA.</u>

The Company agrees, subject to applicable law, (i) to provide the Trustee, upon written request, with such reasonable tax information as it has obtained in the ordinary course and has readily available in its possession to enable the Trustee to determine whether any payments pursuant to the Indenture and the Notes are subject to the withholding requirements imposed pursuant to Sections 1471 through 1474 of the United States Internal Revenue Code of 1986, as amended (the "<u>Code</u>"), and any regulations or agreements thereunder or official interpretations thereof ("<u>FATCA</u>") and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments under the Indenture and the Notes to the extent necessary to comply with FATCA.

All capitalized terms used herein and not otherwise defined herein shall have the meanings attributed to them in the Thirteenth Supplemental Indenture, dated as of December 16, 2025 (as in effect on the date hereof, the "<u>Supplemental Indenture</u>"), between the Company and The Bank of New York Mellon Trust Company, N.A. (as successor to JPMorgan Chase Bank, N.A.), as trustee (the "<u>Trustee</u>").

The term "<u>Senior Debt Obligations</u>", as used herein, shall include all, loans, advances, debts, liabilities and obligations, howsoever arising (whether or not evidenced by any note or instrument and whether or not for the payment of money), direct or indirect, absolute or contingent, due or to become due, now existing or hereafter arising (collectively, as used herein, "<u>Obligations</u>") of the Company now or hereafter existing in respect of Senior Debt (as defined herein) and any amendments, modifications, deferrals, renewals or extensions of any such Senior Debt, or of any notes or evidences of indebtedness heretofore or hereafter issued in evidence of or in exchange for any such Obligation, whether for principal, interest (including interest payable in respect of any such Obligations subsequent to the commencement of any proceeding against or with respect to the Company under any chapter of the Bankruptcy Code, 11 U.S.C. § 101 *et seq.* (the "<u>Bankruptcy Code</u>"), or any provision of corresponding bankruptcy, insolvency or commercial reorganization legislation of any other jurisdiction, whether or not such interest is an allowed claim enforceable against the debtor, and whether or not the holder of such obligation would be otherwise entitled to receive dividends or payments with respect to any such interest or any such proceeding), premium (including Make-Whole Amount), if any, fees, expenses or otherwise.

The term "<u>Senior Debt</u>", as used herein, shall mean (i) all Senior Secured Debt and (ii) all unsecured Debt of the Company permitted to be incurred by the Company pursuant to the Mortgage Indenture or the Supplemental Indenture which is not subject to any subordination terms whether or not similar to those set forth in this instrument.

The term "<u>Subordinated Debt</u>", as used herein, shall mean all Obligations of the Company evidenced by this instrument owing to any Person now or hereafter existing hereunder (whether created directly or acquired by assignment or otherwise), whether for principal, interest (including, without limitation, interest accruing after the filing of a petition initiating any bankruptcy proceeding described in the definition of Senior Debt Obligations, whether or not such interest accrues after the filing of such petition for purposes of the Bankruptcy Code or is an allowed claim in such proceeding), fees, expenses or otherwise.

On and after the Closing Date, no payment on account of principal, interest, fees, premium, expenses or otherwise on this Subordinated Debt shall be made by the Company in cash or otherwise unless (a) full payment of all amounts then due and payable on all Senior Debt Obligations has been made, (b) such payment would be permitted by the Indenture and any Senior Debt Document (as defined below) and (c) immediately after giving effect to such payment, there shall not exist any Default or Event of Default. Any such payment permitted pursuant to this paragraph is hereinafter referred to as a "Permitted Payment". For the purposes of these provisions, no Senior Debt Obligations shall be deemed to have been paid in full until the obligee of such Senior Debt Obligations shall have received payment in full in cash.

Ex. B-1

Upon any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding up or total or partial liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, then and in any such event all principal, premium and interest and all other amounts due or to become due upon all Senior Debt Obligations shall first be paid in full before the holders of the Subordinated Debt shall be entitled to retain any assets so paid or distributed in respect of the Subordinated Debt (whether for principal, premium, interest or otherwise), and upon any such dissolution or winding up or liquidation or reorganization, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the holders of the Subordinated Debt would be entitled, except as otherwise provided herein, shall be paid *pro rata* among the holders of Senior Debt Obligations by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the holders of the Subordinated Debt if received by them. So long as any Senior Debt Obligations are outstanding, the holder of this instrument shall not commence, or join with any creditor other than the Trustee or the Senior Debt Parties (as hereinafter defined) in commencing, or directly or indirectly causing the Company to commence, or assist the Company in commencing, any proceeding referred to in the preceding sentence.

The holder of this instrument hereby irrevocably authorizes and empowers (without imposing any obligation on) each Person (each such Person a "<u>Senior Debt Party</u>" and collectively, the "<u>Senior Debt Parties</u>") that has entered into an agreement, instrument, or other document evidencing or relating to any Senior Debt Obligation (each such agreement, instrument or other document, a "<u>Senior Debt Document</u>") as a lender or creditor and such Senior Debt Party's representatives, under the circumstances set forth in the immediately preceding paragraph, to demand, sue for, collect and receive every such payment or distribution described therein and give acquittance therefor, to file claims and proofs of claims in any statutory or nonstatutory proceeding, to vote such Senior Debt Party's ratable share of the full amount of the Subordinated Debt evidenced by this instrument in its sole discretion in connection with any resolution, arrangement, plan of reorganization, compromise, settlement or extension and to take all such other action (including, without limitation, the right to participate in any composition of creditors and the right to vote such Senior Debt Party's ratable share of the full amount of the Subordinated Debt at creditors' meetings for the election of trustees, acceptances of plans and otherwise), in the name of the holder of the Subordinated Debt evidenced by this instrument or otherwise, as such Senior Debt Party's representatives may deem necessary or desirable for the enforcement of the subordination provisions of this instrument. The holder of this instrument shall execute and deliver to each Senior Debt Party and such holder's representatives all such further instruments confirming the foregoing authorization, and all such powers of attorney, proofs of claim, assignments of claim and other instruments, and shall take all such other action as may be reasonably requested by such holder or such holder's representatives in order to enable such holder to enforce all claims upon or in respect of such holder's ratable share of the Subordinated Debt evidenced by this instrument.

The holder of this instrument shall not, without the prior written consent of the Senior Debt Parties, have any right to accelerate payment of, or institute any proceeding to enforce, the Subordinated Debt so long as any Senior Debt Obligations are outstanding, unless and until all Senior Debt Parties have accelerated payment thereof and commenced proceedings to enforce such Senior Debt Obligations.

After the payment in full of all amounts due in respect of Senior Debt Obligations, the holder or holders of the Subordinated Debt shall be subrogated to the rights of the Senior Debt Parties to receive payments or distributions of cash, property or securities of the Company applicable to Senior Debt Obligations until the principal of, premium on, interest on and all other amounts due or to become due with respect to the Subordinated Debt shall be paid in full subject to the terms and conditions of the Subordinated Debt or of any agreement among the holders of the Subordinated Debt and other Subordinated Debt of the Company.

Ex. B-2

If any payment (other than a Permitted Payment) or distribution of assets of the Company of any kind or character, whether in cash, property or securities, shall be received by the holder of the Subordinated Debt in such capacity before all Senior Debt Obligations are paid in full, such payment or distribution will be held in trust for the benefit of, and shall be immediately paid over *pro rata* among the Senior Debt Parties, for application to the payment in full of Senior Debt Obligations, until all Senior Debt Obligations shall have been paid in full.

Nothing contained in this instrument is intended to or shall impair as between the Company, its creditors (other than the Senior Debt Parties) and the holders of the Subordinated Debt, the obligations of the Company to pay to the holders of the Subordinated Debt, as and when the same shall become due and payable in accordance with their terms, or to affect the relative rights of the holders of the Subordinated Debt and creditors of the Company (other than the Senior Debt Parties).

The Senior Debt Parties shall not be prejudiced in their rights to enforce the subordination contained herein in accordance with the terms hereof by any act or failure to act on the part of the Company.

The holder of this instrument agrees to execute and deliver such further documents and to do such other acts and things as the Senior Debt Parties may reasonably request in order fully to effect the purposes of these subordination provisions. Each holder of this instrument by its acceptance hereof authorizes and directs the trustee or other representative, if any, of the Subordinated Debt represented by this instrument on its behalf to take such further action as may be necessary to effectuate the subordination as provided herein and appoints such trustee or other representative, if any, as its attorney-in-fact for any and all such purposes.

The subordination effected by these provisions, and the rights of the Senior Debt Parties, shall not be affected by (i) any amendment of, or addition or supplement to, the Financing Agreements, any other Senior Debt Document, or any other document evidencing or securing Senior Debt Obligations, (ii) any exercise or non-exercise of any right, power or remedy under or in respect to the Financing Agreements, any other Senior Debt Document, or any other document evidencing or securing Senior Debt Obligations or (iii) any waiver, consent, release, indulgence, extension, renewal, modification, delay, or other action, inaction or omission, in respect of the Financing Agreements, any other Senior Debt Document, or any other document evidencing or securing Senior Debt Obligations; whether or not any holder of any Subordinated Debt shall have had notice or knowledge of any of the foregoing.

No failure on the part of any Senior Debt Party to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor all any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by Law.

The holder of this instrument and the Company each hereby waive promptness, diligence, notice of acceptance and any other notice with respect to any of the Senior Debt Obligations and these terms of subordination and any requirement that the Trustee or any Senior Debt Party protect, secure, perfect or insure any Lien or any property subject thereto or exhaust any right to take any action against the Company or any other Person or any Mortgaged Property.

These terms of subordination shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Senior Debt Obligations is rescinded or must otherwise be returned by the Trustee or any Senior Debt Party upon the insolvency, bankruptcy or reorganization of the Company or otherwise, all as though such payment had not been made.

Ex. B-3

The provisions of these terms of subordination constitute a continuing agreement and shall (i) remain in full force and effect until the indefeasible payment in full of the Senior Debt Obligations and the termination or expiration of all obligations to extend credit under the Senior Debt Documents, (ii) be binding upon the holder of this instrument, the Company and its successors, transferees and assignees and (iii) inure to the benefit of, and be enforceable by, the Trustee and each Senior Debt Party. Without limiting the generality of the foregoing clause (iii), each Senior Debt Party may assign or otherwise transfer all or any portion of its rights and obligations under all or any of the Senior Debt Documents to any other Person (to the extent permitted by the Senior Debt Documents), and such other Person shall thereupon become vested with all the rights in respect thereof granted to such Senior Debt Party herein or otherwise.

This instrument shall be governed by and construed in accordance with, the laws of the State of New York.

Ex. B-4
