Distribution, then the amounts payable directly by the Capital Trusts on the respective TruPS shall be paid on a pro rata basis. The holders of the common securities will be entitled to receive distributions upon any such Liquidation pro rata with the holders of the TruPS, except that if an Event of Default (as defined in the Declarations) has occurred and is continuing the TruPS shall have a preference over the common securities with regard to such distributions.

Notwithstanding the foregoing, the Capital Trust shall not, except with the consent of holders of 100% in liquidation amount of the TruPS, consolidate, amalgamate, merge with or into, or be replaced by any other entity or permit any other entity to consolidate, amalgamate, merge with or into, or replace it, if in the opinion of a nationally recognized independent tax counsel experienced in such matters, such consolidation, amalgamation, merger or replacement would cause the Capital Trust or the Successor Entity to be classified as other than a grantor trust for United States federal income tax purposes.

Beginning on December 18, 2025, we have the right to call the notes for mandatory redemption, in whole and not in part, on any redemption date and pay to holders 100% of the principal amount of the notes plus accrued and unpaid interest to but excluding the date of such redemption.

The 18th day of each March, June, September and December beginning in December 2025, provided that if any such day is not a Business Day, the applicable redemption date will be the next succeeding Business Day. No additional interest will accrue as a result of such delay in payment.

“Business Day” means any day that is not a Saturday or Sunday and that, in New York City, is not a day on which banking institutions are authorized or obligated by law or executive order to close.

Events of default are: (i) failure of CGMH or Citigroup to pay required interest on any debt security of such series for 30 days; (ii) failure of CGMH or Citigroup to pay principal, other than a scheduled installment payment to a sinking fund, on any debt security of such series when due; (iii) failure of CGMH or Citigroup to make any required scheduled installment payment to a sinking fund for 30 days on debt securities of such series; (iv) failure of CGMH to perform for 90 days after notice any other covenant in the Indenture applicable to it other than a covenant included in the Indenture solely for the benefit of a series of debt securities other than such series; and (v) certain events of bankruptcy or insolvency of CGMH, whether voluntary or not.

Events of bankruptcy or insolvency or resolution proceedings relating to Citigroup will not constitute an event of default with respect to any series of debt securities. Similarly, any breach of a covenant in the Indenture by Citigroup (other than payment default) will not constitute an event of default with respect to any series of debt securities. Furthermore, it will not constitute an event of default with respect to any series of debt securities if the guarantee of the debt security by Citigroup ceases to be in full force and effect for any reason. Therefore, events of bankruptcy or insolvency or resolution proceedings relating to Citigroup (in the absence of any such event occurring with respect to CGMH) will not permit any of the debt securities to be declared due and payable. In addition, a breach of a covenant by Citigroup (including, for example, a breach of Citigroup’s covenants with respect to mergers, the sale of all or substantially all its assets or limitations on liens), other than payment default, will not permit any of the debt securities to be declared due and payable.

If an event of default regarding debt securities of any series issued under the Indenture should occur and be continuing, either the Trustee or the holders of 25% in the principal amount of outstanding debt securities of such series may declare each debt security of that series due and payable. CGMH and Citigroup are required to file annually with the Trustee a statement of an officer as to the fulfillment by CGMH and Citigroup of its obligations under the Indenture during the preceding year.

No event of default regarding one series of debt securities issued under the Indenture is necessarily an event of default regarding any other series of debt securities. For purposes of this section, “series” refers to debt securities having identical terms, except as to issue date, principal amount and, if applicable, the date from which interest begins to accrue.

Holders of a majority in principal amount of the outstanding debt securities of any series will be entitled to control certain actions of the Trustee and to waive past defaults regarding such series. The Trustee generally will not be under any obligation to act at the request, order or direction of any of the holders of debt securities, unless one or more of such holders shall have offered to the Trustee reasonable security or indemnity satisfactory to it.

Before any holder of any series of debt securities may institute action for any remedy, except payment on such holder’s debt security when due, the holders of not less than 25% in principal amount of the debt securities of that series outstanding must request the Trustee to take action. Holders must also offer security and indemnity reasonably satisfactory to the Trustee against liabilities incurred by the Trustee for taking such action.

CGMH, Citigroup and the Trustee can enter into supplemental indentures to establish the form and terms of any series of debt securities without obtaining the consent of any holder of debt securities. CGMH, Citigroup and the Trustee may, with the consent of the holders of at least a majority in aggregate principal amount of the debt securities of a series that are affected by such modification, modify the Indenture or the rights of the holders of the securities of such series to be affected.

No such modification may, without the consent of the holder of each security so affected: (i) extend the fixed date on which the principal or any installment of interest on any such securities is due and payable; (ii) reduce the rate of interest on such securities; (iii) reduce the principal amount of such securities; (iv) reduce the principal amount of any securities issued originally at a discount that would be due and payable upon a declaration of the acceleration of the maturity thereof; (v) change the currency in which any such securities are payable; or (vi) impair the right to sue for the enforcement of any payment on or after the fixed date on which such payment is due and payable

In addition, no such modification may: (i) reduce the percentage of securities referred to above whose holders need to consent to the modification without the consent of such holders; or (ii) change the rights, duties or immunities of the Trustee unless the Trustee agrees to such change.
