(1) the latest of (i) two years following the last date of original issuance of the Unit Securities, (ii) two years following the first date on which no Warrants are outstanding and (iii) if all of the Warrants expire unexercised, the expiration date of the Warrants; or

(2) such shorter period that will terminate when (x) all of the Holders of Transfer Restricted Securities are able to sell all Transfer Restricted Securities immediately without restriction pursuant to Rule 144(k) under the Securities Act or any successor rule thereto, (y) when all Transfer Restricted Securities have ceased to be outstanding (whether as a result of redemption, repurchase and cancellation, conversion or otherwise) or (z) all Transfer Restricted Securities of Holders that complete and deliver in a timely manner the Holder Questionnaire are registered under the Shelf Registration Statement and have been disposed of in accordance with the Shelf Registration Statement.

(b) No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in the Shelf Registration Statement pursuant to this Agreement unless such Holder furnishes to the Company in writing, such information as the Company may reasonably request for use in connection with the Shelf Registration Statement or Prospectus or preliminary Prospectus included therein and in any application to be filed with or under state securities laws (the form of which request is attached hereto as Exhibit A and is referred to herein as the "Holder Questionnaire").

(ii) the Shelf Registration Statement has not been declared effective by the Commission prior to or on the Effectiveness Target Date;

(iii) except as provided in Section 4(b)(i) hereof, the Shelf Registration Statement is filed and declared effective but, during the Effectiveness Period, shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded within five Business Days by a post-effective amendment to the Shelf Registration Statement or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act that cures such failure and, in the case of a post-effective amendment, is itself immediately declared effective; or

(iv) (A) prior to or on the 45^th or 75^th day, as the case may be, of any Suspension Period, such suspension has not been terminated or (B) Suspension Periods exceed an aggregate of 90 days in any 360 day period,

(each such event referred to in foregoing clauses (i) through (iv), a "Registration Default"), the Company hereby agrees to pay liquidated damages ("Liquidated Damages") with respect to the Transfer Restricted Securities from and including the day following the Registration Default to but excluding the day on which the Registration Default has been cured, accruing at a rate:

All obligations of the Issuers set forth in this Section 3 that are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such Transfer Restricted Security shall have been satisfied in full.

The Liquidated Damages set forth above shall be the exclusive monetary remedy available to the Holders of Transfer Restricted Securities for such Registration Default.

4. Registration Procedures.

(a) In connection with the Shelf Registration Statement, the Issuers shall comply with all the provisions of Section 4(b) hereof and shall use its best efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and pursuant thereto, shall as expeditiously as possible prepare and file with the Commission a Shelf Registration Statement relating to the registration on any appropriate form under the Securities Act.

(b) In connection with the Shelf Registration Statement and any Prospectus required by this Agreement to permit the sale or resale of Transfer Restricted Securities, the Issuers shall:

(i) Subject to any notice by the Company in accordance with this Section 4(b) of the existence of any fact or event of the kind described in Section 4(b)(iii)(D), use its reasonable best efforts to keep the Shelf Registration Statement continuously effective during the Effectiveness Period; upon the occurrence of any event that would cause the Shelf Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not be effective and usable for resale of Transfer Restricted Securities during the Effectiveness Period, the Issuers shall file promptly an appropriate amendment to the Shelf Registration Statement or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use its best efforts to cause such amendment to be declared effective and the Shelf Registration Statement and the related Prospectus to become usable for their intended purposes as soon as practicable thereafter. Notwithstanding the foregoing, the Company may suspend the effectiveness of the Shelf Registration Statement by written notice to the Holders for a period not to exceed an aggregate of 45 days in any 90-day period (each such period, a "Suspension Period") if:

(x) an event occurs and is continuing as a result of which the Shelf Registration Statement would, in the Company's reasonable judgment, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and

(y) the Company reasonably determines that the disclosure of such event at such time would have a material adverse effect on the business of the Company (and its subsidiaries, if any, taken as a whole);

provided that in the event the disclosure relates to a previously undisclosed proposed or pending material business transaction, the disclosure of which would impede the Company's ability to consummate such transaction, the Company may extend a Suspension Period from 45 days to 75 days; provided, however, that Suspension Periods shall not exceed an aggregate of 90 days in any 360-day period.

(ii) Prepare and file with the Commission such amendments and post-effective amendments to the Shelf Registration Statement as may be necessary to keep the Shelf Registration Statement effective during the Effectiveness Period; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in the Shelf Registration Statement or supplement to the Prospectus; provided that in no event will such method(s) of distribution take the form of an Underwritten Offering without the prior agreement of the Company, which agreement will not be unreasonably withheld.

(iii) Advise the underwriter(s), if any, and selling Holders promptly (but in any event within five Business Days) and, if requested by such Persons, to confirm such advice in writing:

(A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to the Shelf Registration Statement or any post-effective amendment thereto, when the same has become effective,

(B) of any request by the Commission for amendments to the Shelf Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto,

(C) of the issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, or

(D) of the existence of any fact or the happening of any event, during the Effectiveness Period, that makes any statement of a material fact made in the Shelf Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Shelf Registration Statement or the Prospectus in order to make the statements therein not misleading.

If at any time the Commission shall issue any stop order suspending the effectiveness of the Shelf Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or Blue Sky laws, the Issuers shall use their reasonable best efforts to obtain the withdrawal or lifting of such order at the earliest possible time and will provide to the Initial Purchaser and each Holder who is named in the Shelf Registration Statement prompt notice of the withdrawal of any such order.

alleged untrue statement or omission of a material fact contained in the Prospectus delivered by the Holder, so long as the Prospectus, as amended or supplemented, has been delivered to such Holder prior to such time. The foregoing indemnity agreement is in addition to any liability which the Company or the Trust may otherwise have to any Indemnified Holder.

(b) Each Holder, severally and not jointly, shall indemnify and hold harmless each Issuer, its officers and employees and each person, if any, who controls the Issuer within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Issuer or any such officer, employee or controlling person may become subject, insofar as any such loss, claim, damage or liability or action arises out of, or is based upon:

(i) any untrue statement or alleged untrue statement of any material fact contained in the Shelf Registration Statement or Prospectus or any amendment or supplement thereto or any Blue Sky Application; or

(ii) the omission or the alleged omission to state therein any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading,

but in each case only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to an Issuer by or on behalf of such Holder (or its related Indemnified Holder) specifically for use therein, and shall reimburse the Issuer and any such officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Issuer or any such officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which any Holder may otherwise have to either Issuer and any such officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 6 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 6, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 6 except to the extent it has been materially prejudiced by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 6. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 6 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Holders shall have the right to employ one separate firm to represent jointly the Holders and their officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Holders against the Company under this Section 6 if, in the reasonable judgment of the Holders seeking indemnification, it is advisable for the Holders and such officers, employees and controlling persons to be jointly represented by separate counsel, and in that event the fees and expenses of such separate counsel shall be paid by the Company. No indemnifying party shall:

(i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld) settle or compromise or consent to the entry of any judgment with respect

to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, or

(ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss of liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 6 shall for any reason be unavailable or insufficient to hold harmless an indemnified party under Section 6(a) or 6(b) in respect of any loss, claim, damage or liability (or action in respect thereof) referred to therein, each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability (or action in respect thereof):

(i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers from the offering and sale of the Transfer Restricted Securities on the one hand and a Holder with respect to the sale by such Holder of the Transfer Restricted Securities on the other, or

(ii) if the allocation provided by clause (6)(d)(i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 6(d)(i) but also the relative fault of the Issuers on the one hand and the Holders on the other in connection with the statements or omissions or alleged statements or alleged omissions that resulted in such loss, claim, damage or liability (or action in respect thereof), as well as any other relevant equitable considerations.

The relative benefits received by the Issuers on the one hand and a Holder on the other with respect to such offering and such sale shall be deemed to be in the same proportion as the total net proceeds from the offering of the Units purchased under the Purchase Agreement (before deducting expenses) received by the Trust, on the one hand, bear to the total net gain received by such Holder with respect to its sale of Transfer Restricted Securities on the other. The relative fault of the parties shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by an Issuer on the one hand or the Holders on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. Each Issuer and each Holder agree that it would not be just and equitable if the amount of contribution pursuant to this Section 6(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 6 shall be deemed to include, for purposes of this Section 6, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending or preparing to defend any such action or claim. Notwithstanding the provisions of this Section 6, no Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Transfer Restricted Securities purchased by it were resold exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of any 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders' obligations to contribute as provided in this Section 6(d) are several and not joint.

7. Rule 144. In the event either Issuer is not subject to Section 13 or 15(d) of the Exchange Act, the Company hereby agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding, to make available to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities from such Holder or beneficial owner, the information required by Rules 144 and 144A under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144 and Rule 144A, to the extent applicable.

8. Participation in Underwritten Registrations. No Holder may participate in any Underwritten Registration hereunder unless such Holder:

(i) agrees to sell such Holder's Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements; and

(ii) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements.

9. Selection of Underwriters. The Holders of Transfer Restricted Securities covered by the Shelf Registration Statement who desire to do so may sell such Transfer Restricted Securities in an Underwritten Offering if approved by the Company as provided in Section 4(b)(ii). In any such Underwritten Offering, the investment banker or investment bankers and manager or managers that will administer the offering will be selected by a Majority of Holders whose Transfer Restricted Securities are included in such offering; provided, that such investment bankers and managers must be reasonably satisfactory to the Company.

10. Miscellaneous.

(a) Remedies. Each Issuer acknowledges and agrees that any failure by such Issuer to comply with its obligations under Section 2 hereof may result in material irreparable injury to the Initial Purchaser or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchaser or any Holder may obtain such relief as may be required to specifically enforce the Issuers' respective obligations under Section 2 hereof. Each Issuer further agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.

(b) Intentionally omitted.

(c) No Inconsistent Agreements. Neither Issuer will, on or after the date of this Agreement, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. In addition, neither Issuer shall grant to any of its security holders (other than the Holders of Transfer Restricted Securities in such capacity) the right to include any of its securities in the Shelf Registration Statement provided for in this Agreement other than the Transfer Restricted Securities. Neither Issuer has previously entered into any agreement (which has not expired or been terminated) granting any registration rights with respect to its securities to any Person which rights conflict with the provisions hereof.

(d) Amendments and Waivers. This Agreement may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given, unless the Issuers have obtained the written consent of a Majority of Holders.

(e) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail (registered or certified, return receipt requested), telex, facsimile transmission, or air courier guaranteeing overnight delivery:

(i) if to a Holder, at the address set forth on the records of the registrar under the applicable Operative Documents or the transfer agent of the Warrant Stock, as the case may be; and

(ii) if to either Issuer:

WASHINGTON MUTUAL INC.

FORM OF SELLING SECURITYHOLDER NOTICE AND QUESTIONNAIRE

The undersigned beneficial holder of Trust Preferred Income Equity Redeemable Securities? (PIERS?) Units (the "Units") of Washington Mutual Capital Trust 2001 (the "Trust") and Washington Mutual Inc. (the "Company"; together with the Trust, the "Issuers"), preferred securities (liquidation preference $50 per security) of the Trust (each, a "Preferred Security"), warrants (each, a "Warrant") issued by the Company, to purchase shares of common stock of the Company (shares of common stock purchased upon exercise of a Warrant being referred to as "Warrant Stock") or subordinated debentures issued by the Company (the "Debentures"; the Units, Preferred Securities (including the guarantee by the Company of certain payments thereunder), Warrants, Warrant Stock and Debentures being collectively referred to as the "Transfer Restricted Securities") understands that the Issuers have filed, or intend to file, with the Securities and Exchange Commission (the "Commission") a registration statement (the "Shelf Registration Statement"), for the registration and resale under Rule 415 of the Securities Act of 1933, as amended (the "Securities Act"), of the Transfer Restricted Securities in accordance with the terms of the Resale Registration Rights Agreement, dated as of April 30, 2001 (the "Registration Rights Agreement") between the Issuers and ▇▇▇▇▇▇ Brothers Inc.

Each beneficial owner of Transfer Restricted Securities is entitled to the benefits of the Registration Rights Agreement. In order to sell or otherwise dispose of any Transfer Restricted Securities pursuant to the Shelf Registration Statement, a beneficial owner of Transfer Restricted Securities generally will be required to be named as a selling securityholder in the related Prospectus, deliver a Prospectus to purchasers of Transfer Restricted Securities and be bound by those provisions of the Registration Rights Agreement applicable to such beneficial owner (including certain indemnification provisions, as described below). Beneficial owners that do not complete this Notice and Questionnaire and deliver it to the Company as provided below will not be named as selling securityholders in the prospectus and therefore will not be permitted to sell any Transfer Restricted Securities pursuant to the Shelf Registration Statement.

Certain legal consequences arise from being named as a selling securityholder in the Shelf Registration Statement and the related Prospectus. Accordingly, holders and beneficial owners of Transfer Restricted Securities are advised to consult their own securities law counsel regarding the consequences of being named or not being named as a selling securityholder in the Shelf Registration Statement and the related Prospectus.
