          E. The Corporation acknowledges that reliance by each Covered Debtholder upon the covenants in this Replacement Capital Covenant is reasonable and foreseeable by the Corporation and that, were the Corporation to disregard its covenants in this Replacement Capital Covenant, each Covered Debtholder would have sustained an injury as a result of its reliance on such covenants.

     (D) if the Corporation has no outstanding series of long-term indebtedness for money borrowed that is Eligible Debt, but Washington Mutual Bank is a Subsidiary of the Corporation and Washington Mutual Bank has only one outstanding series of long-term indebtedness for money borrowed that is Eligible Debt, such series shall become the Covered Debt commencing on the related Redesignation Date;

          SECTION 4. Notice. In order to give effect to the intent of the Corporation described in Recital D, the Corporation covenants that:

     (a) simultaneously with the execution of this Replacement Capital Covenant or as soon as practicable after the date hereof, the Corporation shall give notice to the Holders of the Initial Covered Debt, in the manner provided in the indenture relating to the Initial Covered Debt, of this Replacement Capital Covenant and the rights granted to such Holders hereunder;

     (c) if a series of the Corporation’s or Washington Mutual Bank’s long-term indebtedness for money borrowed (i) becomes Covered Debt or (ii) ceases to be Covered Debt, the Corporation shall give notice of such occurrence within 30 days to the holders of such long-term indebtedness for money borrowed in the manner provided for in the indenture, fiscal agency agreement or other instrument under which such long-term indebtedness for money borrowed was issued and report such change in the Corporation’s next quarterly report on Form 10-Q or annual report on Form 10-K, as applicable;

     (d) if, and only if, the Corporation ceases to be a reporting company under the Securities Exchange Act, the Corporation shall post on its website the information otherwise required to be included in Securities Exchange Act filings pursuant to clauses (b) and (c) above; and

     (e) (e) promptly upon request by any Holder of Covered Debt, the Corporation shall provide such Holder with an executed copy of this Replacement Capital Covenant.

          SECTION 5. Term. (a) The Covenants in Section 2 shall remain in full force and effect until the earliest date (the “Termination Date”) to occur of (i) the date, if any, on which the Holders of at least 51% by principal amount of the then effective Covered Debt consent or agree in writing to the elimination of such covenants as covenants in favor of such Holders, (ii) the date on which neither the Corporation nor Washington Mutual Bank has any series of outstanding Eligible Senior Debt or Eligible Subordinated Debt (in each case without giving effect to the rating requirement in clause (ii) of the definition of each such term), and (iii) the first date as of which all of the Securities either have been redeemed or repurchased and are beneficially owned by the Corporation or its Subsidiaries.

          SECTION 6. Miscellaneous. (a) This Replacement Capital Covenant shall be governed by and construed in accordance with the laws of the State of New York without regard to choice of law principles.

          (b) This Replacement Capital Covenant shall be binding upon the Corporation and its successors and assigns and shall inure to the benefit of the Covered Debtholders as they exist from time-to-time (it being understood and agreed by the Corporation that any Person who is a Covered Debtholder at the time such Person acquires or sells Covered Debt shall retain its status as a Covered Debtholder for so long as the series of long-term indebtedness for borrowed money owned by such Person is Covered Debt and, if such Person initiates a claim or proceeding to enforce its rights under this Replacement Capital Covenant after the Corporation has violated its covenants in Section 2 and before the series of long-term indebtedness for money borrowed held by such Person is no longer Covered Debt, such Person’s rights under this Replacement Capital Covenant shall not terminate by reason of such series of long-term indebtedness for money borrowed no longer being Covered Debt).

          (c) The Corporation acknowledges that reliance by each Covered Debtholder upon the covenants in this Replacement Capital Covenant is reasonable and foreseeable by the Corporation and that, were the Corporation to disregard its covenants in this Replacement Capital Covenant, each Covered Debtholder would have sustained an injury as a result of its reliance on such covenants.
